 to the *notification* families, which need a subscriber and a module in the
 guest.
 
+### Workbench and generated rows
+
+A hand-written `*-corpus.exp` row costs a VM rebuild and a ~500 s cold boot
+per attempt, so the corpus grew by dozens of rows when it needs thousands. The
+`nlcap-workbench` flavor removes both costs. It is a VM you keep up and drive
+over ssh, and the rows it runs are data (JSON Lines), not Tcl:
+
+```sh
+nix run .#nlcap-ws -- up                        # boot, wait for ssh
+nix run .#nlcap-ws -- run --slug t/fq -- tc qdisc add dev lo root fq
+nix run .#nlcap-ws -- batch nix/microvms/workbench/selftest.rows.jsonl -j 8
+nix run .#nlcap-ws -- down                      # power off, delete the key
+```
+
+- **Nothing in the repo rebuilds it.** The guest has no `xtcp2AllPackage`. The
+  capture helper (`netlink-capture.nix`) and the batch runner
+  (`workbench/nlcap_batch.py`) run by store path through the guest's 9p
+  `/nix/store`, so a new build of either is picked up by the next call, with
+  no reboot. Measured: after a Go test file and its testdata were staged, the
+  rebuilt CLI pointed at the same VM runner and helper store paths. Only the
+  batch runner changed, because its own source had been edited.
+- **Ephemeral ssh key.** `up` makes an ed25519 pair under
+  `$XDG_STATE_HOME/xtcp2-nlcap-ws/`. qemu hands the public half to the guest
+  over `-fw_cfg`, and a oneshot installs it before sshd starts. sshd listens
+  on `127.0.0.1:12061` only, and `down` deletes the key. The workbench owns
+  ports 12059–12061 (`constants.nix` `nlcapWs`), so it can stay up while
+  other sessions boot their VMs on 12055/12056.
+- **Parallel rows.** Netlink taps are per network namespace, so each row gets
+  a fresh netns (`ws<slot>`) with its own `nlmon0`, and `-j N` rows run at
+  once without seeing each other's messages. A row marked `serial` runs alone.
+- **`cache=loose` on the 9p store** is what makes this fast. With microvm.nix's
+  default (no cache), every exec from `/nix/store` took ~0.4 s and one row took
+  27 s. With `cache=loose`:
+
+  | measure | value |
+  |---|---|
+  | cold `up` to ssh | 28 s (98 s without `cache=loose`) |
+  | `ip -V` in the guest | 0.06 s |
+  | one row, alone | ~2.5 s |
+  | 40 rows, `-j 8` on 6 vCPUs | 23.5 s, 0.59 s a row (~38 s at `-j 4`) |
+  | the 6 selftest rows, `-j 8` | 7 s |
+
+**A row** is one JSON object per line: `id` (also the output directory under
+`testdata/<kver>/ws/`), `desc` (starts with `positive:`, `negative:`,
+`boundary:` or `corner:`), `cmd`, and optionally `pre` (setup outside the
+capture window, each step a command or `[command, rc]`), `readback` (named
+dumps captured after the command), `proto`, `floor`, `modules`, `serial`,
+`axes` and `source`, plus `expect`:
+
+| `expect` field | checked by `TestWsCorpusRows` against the pcap |
+|---|---|
+| `rc` | the command's exit status |
+| `sent` | how many requests the command sent |
+| `errno`, `extack` | the kernel's `NLMSG_ERROR` and its extack message |
+| `refused_by` | `none`, `kernel`, `iproute2` (rc ≠ 0 and **zero** requests sent) or `ack-then-fail` |
+| `match` | `{readback, pattern, count}`: the RE2 pattern matches `count` times in the readback's stdout (tdc's verify check) |
+
+Each run writes `cmd.json` beside the pcaps: the row, the guest's kernel and
+iproute2 versions, and the result. `pkg/xtcpnl/xtcpnl_ws_corpus_test.go` turns
+every `cmd.json` into a subtest, and `TestWsRowProblem` checks the oracle
+itself on hand-built observations, including the ones that must fail.
+
+**What the selftest rows already showed.** Three of the six expectations
+first written down were wrong, and the oracle caught each one:
+
+- `ip link add <16-byte name> type dummy` is **not** refused by iproute2. The
+  positional name is checked against `ALTIFNAMSIZ` (iproute2 `afd67550`, "allow
+  to use alternative names as handle"), so the request reaches the kernel.
+  There it fails `IFLA_IFNAME`'s `NLA_STRING` policy (`len = IFNAMSIZ - 1`,
+  `net/core/rtnetlink.c`), with **`ERANGE`**, not `EINVAL`: `validate_nla`
+  starts from `err = -ERANGE` (`lib/nlattr.c`), and the extack reads "Attribute
+  failed policy validation". This is a behavior, not a bug.
+- `ip -6 route add … dev d0 table 4294967295` sends **two** requests: an
+  `RTM_GETLINK` to resolve `d0`, then the `RTM_NEWROUTE`.
+- That request carries `rtm_table = RT_TABLE_UNSPEC` (0) plus `RTA_TABLE`
+  (`iproute_modify`, `ip/iproute.c`). The dump answers with
+  `RT_TABLE_COMPAT` (252) plus `RTA_TABLE` (`rt6_fill_node`,
+  `net/ipv6/route.c`). `TestWsSelftestTableMax` pins both.
+
+The two fresh-boot replays of the selftest batch matched row for row: the
+same status, rc and packet count.
+
+#### tc from tdc (W1)
+
+tdc (`tools/testing/selftests/tc-testing`) is the kernel's own tc suite:
+1334 cases, each a setup list, one command under test with its expected exit
+status, and a verify command whose output must match a pattern a given
+number of times. `nlcapgen tdc` (`tools/nlcapgen`) converts them into
+`nix/microvms/workbench/tdc.rows.jsonl`:
+
+```sh
+go run ./tools/nlcapgen tdc -src ~/Downloads/linux/tools/testing/selftests/tc-testing/tc-tests \
+  -out nix/microvms/workbench/tdc.rows.jsonl -skipped nix/microvms/workbench/tdc.skipped.jsonl \
+  -rev "$(git -C ~/Downloads/linux rev-parse --short=12 HEAD)"
+nix run .#nlcap-ws -- batch nix/microvms/workbench/tdc.rows.jsonl -j 8
+```
+
+- **The mapping.** `$TC`, `$IP` and tdc's device names keep their names
+  (`DEV0`/`DEV1` → the veth pair `v0p0`/`v0p1`, `DUMMY` → `dummy1`, `IFB` →
+  `ifbtdc0`), so the many patterns that name a device still match. The setup
+  becomes `pre`; the verify command becomes the `verify` readback, with
+  `matchPattern`/`matchCount` as `expect.match`; the teardown is dropped,
+  since the namespace is. A row loads its file's module (`sch_`, `cls_` or
+  `act_` plus the file name).
+- **Devices only for nsPlugin cases.** tdc makes the veth, dummy and ifb only
+  for a case that requires `nsPlugin` (1303 of 1334). The other 31 make their
+  own devices (`teql.json` adds `$DUMMY` itself), and tdc runs them alone, so
+  their rows get no devices and are `serial`. A `$ETH` case uses netdevsim,
+  whose device ids are global: it runs `serial`, after removing the device an
+  earlier row left behind.
+- **Patterns keep tdc's flags.** tdc compiles every pattern with
+  `re.DOTALL | re.MULTILINE` (`tdc.py`, verify), so the converter writes
+  `(?sm)` in front of each. Without it, 150 rows failed: their `.*` must
+  cross lines. A pattern RE2 cannot compile, a `matchJSON` check and a
+  pattern that counts scapy traffic are left unchecked, each with its reason
+  in `source.unchecked` (63 `matchJSON`, 17 scapy).
+- **24 cases have no row**, each with its reason in `tdc.skipped.jsonl`: 12
+  run tdc's helper scripts (`./tdc_*`, `./scripts/*`), 4 need a compiled eBPF
+  object, 4 a second physical device, 2 use gact's `random`, which needs
+  `CONFIG_GACT_PROB` (the workbench kernel has it off, so one case failed and
+  the other passed for the wrong reason). One's command under test is
+  `/bin/true` (it tests its setup, which the capture does not see). One,
+  `filters/u32/1234`, sends 4096 requests in one `tc -b` burst, and nlmon
+  dropped 3337 of 4858 datagrams even with the row alone.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_tc_test.go`), on top of
+`TestWsCorpusRows`:
+
+| # | test | holds |
+|---|---|---|
+| O6 | `TestWsTcCorpus` | every tc message in every capture parses (`ParseTcMsg`, `ParseTcAction`, `xtcpnl_tcmsg.go`) and carries no attribute past `TCA_MAX`, `TCA_ROOT_MAX` or `TCA_ACT_MAX` |
+| O3 | `TestWsTcCorpus` | a `tc qdisc`/`class`/`filter` add, change, replace or delete sends what its command line says: kind, handle, parent, prio, protocol, chain and shared blocks. `tcWantFromCmd` reads the line as `tc_qdisc_modify`, `tc_class_modify` and `tc_filter_modify` do, with `get_qdisc_handle`, `get_tc_classid` and `ll_proto_a2n` |
+| O4 | `TestWsTcCorpus` | a qdisc the kernel accepted is in the verify dump: same device and kind, and the same parent and handle where the request named them |
+| O7 | `FuzzParseTcMsg`, `FuzzParseTcAction` | seeded with up to 400 distinct corpus messages each: no panic, and the byte fields a parse returns are copies |
+| — | `TestWsSizeBudget` | each kernel's `ws/` stays under 64 MB of file bytes (20 MB until W4b) |
+
+O3 reads 546 requests and O4 checks 254 round trips. Commands outside the
+model (pipelines, quoted arguments, `tc -b`, actions, chains) are counted
+out rather than guessed at. Each oracle and the model have hand-built rows
+that must fail; 17 of 18 mutants of them were killed, and the survivor was
+equivalent (it removed a type mask the attribute walker already applies).
+
+**What the tdc rows showed:**
+
+- **Action dumps are numbered from 0.** `ParseTcAction` first refused nests
+  outside 1–32, which is how tc numbers a request. The kernel's dump
+  numbers from 0, and past 32 when the dump sets
+  `TCA_ACT_FLAG_LARGE_DUMP_ON` (`tcf_dump_walker`,
+  `net/sched/act_api.c`). A flush's reply is one nest 0 holding
+  `TCA_ACT_KIND` and `TCA_FCNT`, whose value 7 reads as `TCA_ACT_FLAGS`
+  (`tcf_del_walker`). The parser now refuses no order: 233 dumps failed O6
+  until it did.
+- **tc looks the device up before refusing an argument.** For a bad ematch
+  or an out-of-range index, tc exits 1 or 255 after one acknowledged
+  `RTM_GETLINK` and no tc request: "ack-then-fail" by the W0 rule. A row
+  that expects that rc has said it knew, so `wsRowProblem` accepts it then
+  (61 tdc rows), and still refuses it with any other rc.
+- **`actions/batch-delete/8135` predates its fix.** It tests f67b3ed1308d
+  ("net/sched: act_api: reject duplicate actions in a batch", 7.4 merge
+  window). On 7.3.0 the delete still fails (rc 255), but the first action is
+  already gone, so tdc's pattern (the action survives) cannot match. The row
+  stays, so its capture records 7.3's behavior; its pattern is unchecked,
+  with that reason.
+- **Determinism.** Three batches, the last two on fresh boots, gave every
+  row the same status, rc, message types and request count (dumps of shared
+  state are compared as type sets). A batch of 1310 rows takes ~12 minutes at
+  `-j 8`. The corpus is 4.1 MB of file bytes in ~9,200 files (34 MB of disk
+  blocks, which is not what git stores).
+
+#### Grammar matrix (W2)
+
+W2 is four commits, each verified on its own:
+
+- **W2a:** the generator and `ip route` for IPv4 and IPv6, with O3 and O4.
+  This section covers it first.
+- **W2b:** `ip rule` and `ip nexthop`, in [its own part below](#w2b-ip-rule-and-ip-nexthop).
+- **W2c:** O5, the goip differential over W2a's and W2b's rows, in
+  [its own part below](#w2c-o5-the-goip-differential).
+- **W2d:** rows mined from the fib selftests, with O5 applied to them.
+
+`nlcapgen matrix` (`tools/nlcapgen/matrix.go`) builds rows from a table of
+axes for each command. Each axis lists values, marked boundary or corner
+where they are. `matrix_route.go` has two spaces:
+
+- **route4**, 10 axes: verb, destination, type, table, metric, protocol,
+  scope, MTU/advmss, source and nexthop.
+- **route6**, 11 axes: the same, without scope, plus pref and expires.
+
+```sh
+go run ./tools/nlcapgen matrix -family route -seed 1 -random 40 \
+  -out nix/microvms/workbench/route.rows.jsonl
+nix run .#nlcap-ws -- batch nix/microvms/workbench/route.rows.jsonl -j 8
+```
+
+- **Strategies.** The generator writes these row groups:
+  - each-choice (`ec-`): every value appears at least once;
+  - pairwise (`pw-`): every pair of values from two axes appears in some
+    row, built greedily (AETG style);
+  - boundary (`bd-`): row n takes the n-th boundary value of every axis;
+  - seeded random (`rn<seed>-`): a SplitMix64 generator, so a seed always
+    gives the same rows, and a new seed gives new ones.
+
+  A repeated assignment is dropped, and the same seed gives the same file
+  byte for byte.
+- **Negatives.** These come from four sources:
+  - an *exclusion* (a pair of values the kernel or iproute2 refuses) keeps
+    the pair out of every positive row and writes one row expecting the
+    refusal;
+  - a *bad value* changes one axis of a positive row;
+  - `Judge` predicts refusals that depend on three axes or more, such as
+    IPv4 scope, which turns on type, scope and nexthop together. A judged
+    row stays in the matrix as a negative;
+  - `deriveRoute` adds repeated adds (EEXIST) and deletes of routes never
+    added (ESRCH).
+
+  Each negative records the errno it expects, and `TestWsCorpusRows`
+  checks it.
+- **Rows.** 343 rows: 228 the kernel accepts (13 positive, 78 boundary,
+  137 corner) and 115 negatives:
+
+  | outcome | rows |
+  |---|---|
+  | EINVAL | 55 |
+  | ESRCH | 19 |
+  | EEXIST | 10 |
+  | ENODEV | 10 |

+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_route_test.go`), on top of
+`TestWsCorpusRows`:
+
+| # | test | holds |
+|---|---|---|
+| O3 | `TestWsRouteCorpus` | an accepted row sends one request, built from its axes the way `iproute_modify` builds it. The test checks the verb's flags, the `rtmsg` (protocol, type, scope and table, plus the table rule: under 256 in the header, otherwise `RT_TABLE_UNSPEC` there and `RTA_TABLE` u32), the exact set of attributes and their widths, the values, `rtnh_hops` = weight − 1, and `RTA_METRICS` |
+| O4 | `TestWsRouteCorpus` | after an accepted write, the `ip route show table all` dump has the route: same family, prefix, table, type and metric (IPv6 stores metric 0 as 1024). After an accepted delete, the route is gone |
+
+O3 checks 329 requests and O4 checks 228 round trips. The model and the oracles have
+unit tables (`TestRouteWantFromAxes`, `TestRouteRequestProblem`,
+`TestRouteDumpHas`, `TestRouteJudge`, `TestBuildRouteOrder`,
+`TestMatrixJudge`). 17 of 17 mutants of the oracles, the model and the
+generator were killed, each by a failing test.
+
+**What the route rows showed** (kernel 7.3.0, iproute2 7.2.0):
+
+- **An IPv4 reject route accepts `nhid`, and its scope is never checked.**
+  `fib_create_info` refuses a gateway, device or multipath on a
+  blackhole, unreachable, prohibit or throw route. It does not refuse a
+  nexthop id, and it then jumps to `link_it`, past every nexthop and scope
+  check (`net/ipv4/fib_semantics.c:1478-1484`). So
+  `ip route add blackhole 0.0.0.0/0 scope host nhid 10` succeeds.
+- **An IPv6 multipath reject route fails with EEXIST.**
+  `fib6_nh_init` puts a reject route's nexthop on lo before it stores a
+  gateway (`net/ipv6/route.c:3623-3640`), so every nexthop is identical.
+  The second is then a duplicate of the first (`rt6_duplicate_nexthop`,
+  `net/ipv6/ip6_fib.c:1136-1142`). The same happens for add, append,
+  prepend and replace, and no extended-ack text explains it.
+- **An IPv6 reject route can't be deleted with the arguments it was added
+  with.** The add accepts `dev d0` or `via …` and drops them, for the same
+  reason. A delete naming them then matches nothing in `ip6_route_del`
+  and fails with ESRCH (6 rows). Deleting by prefix, or by nhid, works.
+- **A gateway at IPv4 link scope fails with ENETUNREACH, not EINVAL.**
+  `fib_check_nh_v4_gw` looks the gateway up at scope host, where only
+  local routes live, and returns the lookup's own error with the
+  extended-ack text "Nexthop has invalid gateway"
+  (`fib_semantics.c:1211-1242`). Onlink at that scope is EINVAL
+  ("Nexthop has invalid scope", `:1183-1186`). Broadcast and multicast
+  routes get link scope from iproute2 when no scope is given, so they
+  hit this too. An IPv6 gateway (RFC 5549) and an nhid without onlink
+  pass. At host scope, any gateway or second nexthop is EINVAL
+  (`:1510-1519`, `net/ipv4/nexthop.c:1626-1641`).
+- **Every non-reject IPv6 type needs a device** (ENODEV), including
+  local and anycast.
+- **`default` sends an all-zero `RTA_DST`.** With `-4` or `-6`,
+  `get_addr_1` sizes `default` to the family (`lib/utils.c:579-586`), so
+  it sends the same request as `0.0.0.0/0` or `::/0`. The O3 model first
+  assumed no `RTA_DST`, so O3 failed every accepted `default` row (28)
+  until the model was corrected.
+- **`to` goes before the type.** `iproute_modify` takes `to` only ahead
+  of the type (`ip/iproute.c:1558-1566`), as `ip-route(8)` writes it
+  (`to TYPE PREFIX`). `ip route add unreachable to …` exits 1. The first
+  batch had 14 rows written that way, which was a generator bug. A
+  negative row keeps the wrong order.
+- **A bad nexthop weight is refused after the device lookup.**
+  `parse_one_nh` resolves `dev` (one acknowledged `RTM_GETLINK`) before it
+  reads `weight`, so weight 0 or 257 is "ack-then-fail" with rc 255, as
+  tc's bad arguments are in W1.
+- **Determinism.** The same 343 rows ran three times, the second on a
+  fresh boot, and wscmp found every row with the same status, rc and
+  message types each time. A batch takes ~90 s at `-j 8`, and a cold
+  `nlcap-ws up` takes 21 s. The corpus is 1.0 MB of file bytes in 2401
+  files.
+
+##### W2b: `ip rule` and `ip nexthop`
+
+The same generator, with two more families:
+
+```sh
+go run ./tools/nlcapgen matrix -family rule -seed 1 -random 40 \
+  -out nix/microvms/workbench/rule.rows.jsonl
+go run ./tools/nlcapgen matrix -family nexthop -seed 1 -random 40 \
+  -out nix/microvms/workbench/nexthop.rows.jsonl
+```
+
+- **`matrix_rule.go`:** rule4 and rule6, 17 axes each: verb, `not`,
+  from, to, pref, fwmark, iif, oif, the DS field (tos, dsfield or dscp
+  with its mask), ipproto, sport, dport, uidrange, suppress, protocol,
+  an extra (tun_id, realms or, for IPv6, flowlabel) and the action
+  (lookup, goto, nop, the reject types, l3mdev).
+- **`matrix_nexthop.go`:** nh4 and nh6 (verb, id, kind, protocol), and
+  nhgrp (verb, fam, id, members, type, fdb, hw_stats, protocol). A group
+  row first adds its members, ids 21 to 32, so the id axis (1 and 100)
+  never takes one of theirs.
+- **Judges.** `ruleJudge` refuses a bare `ip rule add` or `del` (iproute2,
+  rc 1) and a goto at or below its own preference ("Backward goto not
+  supported"). `nhJudge` refuses a replace or delete without an id.
+- **Repeats and deletes.** `deriveDupGone` (shared with route) adds a
+  repeated add (EEXIST) and a delete of something never added (ENOENT).
+  It only repeats a row that names a preference or an id: without one,
+  the kernel picks a new preference or id, so the second add makes a
+  second object instead of failing.
+- **Rows.**
+
+  | family | rows | accepted | negative |
+  |---|---|---|---|
+  | rule (rule4 203, rule6 203) | 406 | 351 (14 positive, 78 boundary, 259 corner) | 55 |

+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_rule_test.go`,
+`xtcpnl_ws_nexthop_test.go`):
+
+| # | test | holds |
+|---|---|---|
+| O3 | `TestWsRuleCorpus` | the verb's flags; the `fib_rule_hdr` (family, prefix lengths, tos, action and the table rule: under 256 in the header, otherwise `FRA_TABLE` u32); the exact set of `FRA_*` attributes, each width (an interface name with its NUL, a zero-width `FRA_SRC` for `from all`) and value |
+| O4 | `TestWsRuleCorpus` | the `ip rule show` dump has the rule, with the same selectors, preference, action, table and ranges; after a delete it is gone |
+| O3 | `TestWsNexthopCorpus` | the verb's flags; the `nhmsg` (family, protocol, onlink); the attribute set and widths; `NHA_GROUP` as weight − 1 split over `weight` and `weight_high`; `NHA_GROUP_TYPE`; the `NHA_RES_GROUP` nest and what it holds |
+| O4 | `TestWsNexthopCorpus` | the dump has the nexthop by id, with its family, protocol, gateway, device, blackhole, fdb, members and weights (only when the dump fills in `weight_high` or no weight passes 256) and the resilient values named; after a delete the id is gone |
+
+O3 checks 386 rule and 267 nexthop requests; O4 checks 351 and 178 round
+trips. Unit tables: `TestRuleWantFromAxes`, `TestRuleRequestProblem`,
+`TestRuleDumpMatches`, `TestNhWantFromAxes`, `TestNhWantForCmd`,
+`TestNhRequestProblem`, `TestNhDumpMatches`, and in the generator
+`TestRuleJudge`, `TestBuildRule`, `TestNhJudge`, `TestBuildNexthop` and
+`TestMatrixFibRows`, `TestFibPredicates` and `TestNhMembers`. 26 of 26
+mutants of the oracles, the judges, the builders and the generator were
+killed, each by a failing test. The last two tables were added for three
+that first survived: a repeat predicate that always holds, a negative base
+of any kind, and members back at id 1.
+
+**What the rule and nexthop rows showed** (kernel 7.3.0, iproute2 7.2.0):
+
+- **iproute2 7.2.0 can't send a nexthop `dst_port`.** `NHA_DST_PORT`
+  (18) is parsed only from iproute2 commit ad2b2d95 on, after 7.2.0. So
+  `dev d0 dst_port 4789` is ack-then-fail: one `RTM_GETLINK` for `d0`,
+  then rc 255. It is a negative row until the flake moves past it.
+- **`type resilient` sends an empty `NHA_RES_GROUP` when anything
+  follows it.** `parse_nh_group_type_res` opens the nest whenever there
+  is a next argument, even one that isn't a resilient option (`type
+  resilient fdb`). When `type resilient` ends the line, no nest is sent.
+  O3 models both.
+- **A new resilient group needs `buckets`.** Without them the kernel
+  refuses it with EINVAL ("Number of buckets not specified for nexthop
+  group insertion", `net/ipv4/nexthop.c:2692`).
+- **A nexthop on an unknown device fails in the kernel, not in ip.**
+  `ll_name_to_index` asks with an `RTM_GETLINK`, the kernel answers
+  ENODEV, and ip exits 255 ("Device does not exist") without sending the
+  `RTM_NEWNEXTHOP`.
+- **iproute2 takes weight 65536, the kernel doesn't.** `nhgrp_set_weight`
+  stores 65535 across `weight` and `weight_high`; the kernel refuses it
+  with EINVAL. 65535 is the largest it accepts.
+- **A DSCP of 64 is ERANGE.** iproute2 sends `FRA_DSCP` 64 as given, and
+  `fib_rule_policy`'s `NLA_POLICY_MAX` refuses it ("Error parsing msg")
+  with ERANGE, not EINVAL.
+- **A rule port range must end below 65535.** `sport 65535` passes
+  iproute2 and the kernel refuses it ("Invalid sport range"); 65534 is
+  accepted. An IPv4 `tos 0xb8` (past `IPTOS_TOS_MASK`) is EINVAL too.
+- **`from all` sends a zero-length `FRA_SRC`.** The first O3 model sent
+  the family's width of zeros, which is what `from 0.0.0.0/0` sends.
+- **A repeated rule without a preference isn't EEXIST.**
+  `fib_default_rule_pref` gives the second add a new preference, so it
+  succeeds as a second rule.
+- **Determinism.** Both rows files ran twice, the second on a fresh
+  boot, and wscmp found every row with the same status, rc and message
+  types. The two families' corpus is 1.5 MB in 4802 files.
+
+##### W2c: O5, the goip differential
+
+`TestWsGoipDifferential` (`internal/goip/ws_differential_test.go`) runs
+every route, rule and nexthop row through goip offline, against the row's
+own `ip.pcap`:
+
+- goip's `RTM_GETLINK` lookups are answered from the capture, so `d0`
+  resolves to the ifindex the kernel gave ip;
+- goip's write goes to `GOIP_WRITE_OUT` and is never sent;
+- ip's requests are split into its leading `RTM_GETLINK` lookups and the
+  rest. The lookups and the write are compared separately, so a lookup
+  difference can't hide whether the write matches.
+
+Each row's write gets one outcome:
+
+| outcome | means |
+|---|---|
+| same | the same write byte for byte (seq and pid zeroed), or both refuse at a check goip implements |
+| refuses | goip refuses a command ip sent, or goip and ip both refuse but goip's reason is "not implemented" |
+| sends | goip writes a request ip refused to send |
+| differs | both write, and the writes differ; the report names the nlmsg flags, the family header or the attribute types |
+
+Every row whose outcome isn't "same", and every row whose lookups differ
+other than in the known way, is listed in
+`internal/goip/testdata/ws-differential.txt`. A new divergence and a fixed
+one both fail the test until the file is regenerated with `-update-ws-o5`.
+
+| space | same | refuses | sends | differs | lookups differ |
+|---|---|---|---|---|---|
+| route4 | 132 | 58 | 0 | 0 | 88 |
+| route6 | 55 | 98 | 0 | 0 | 37 |
+| rule4 | 173 | 30 | 0 | 0 | 0 |
+| rule6 | 203 | 0 | 0 | 0 | 0 |
+| nh4 | 78 | 2 | 0 | 0 | 38 |
+| nh6 | 78 | 2 | 0 | 0 | 36 |
+| nhgrp | 81 | 39 | 0 | 0 | 0 |
+
+**What O5 showed:**
+
+- **goip's writes match ip's on every row goip implements.** No row
+  differs.
+- **goip took a `protocol` past 255, and ip doesn't.** `rtnl_rtprot_a2n`
+  refuses a number over 255 (`lib/rt_names.c:293`, in every iproute2
+  release since well before 7.1). goip's rule, nexthop and neigh parsers
+  allowed a u32 and sent its low byte, so `protocol 256` was a write where
+  ip sends nothing (4 "sends" rows). They now refuse it. The nexthop test
+  that expected `protocol 0x1ff` to send 0xff now expects 255 to be the
+  largest it takes, and 256 to be refused.
+- **All 199 lookup differences are `IFLA_EXT_MASK`.** iproute2 7.2.0's
+  `ll_link_get` adds `RTEXT_FILTER_NAME_ONLY` (1<<8, `lib/ll_map.c:276`),
+  so ip asks with 0x109 where goip, which models 7.1, asks with 0x9. goip
+  stays on 7.1 until its parity target moves; the report counts these rows
+  in its header and doesn't list them one by one.
+- **What goip refuses:**
+  - route: 156 rows on keywords goip hasn't implemented (`pref` 68, `nhid`
+    49, `nexthop` 29, `expires` 10);
+  - nexthop: 43 rows on `hw_stats` (41) and `dst_port` (2), which no
+    capture showed before;
+  - rule: 30 rows on `realms`. iproute2 reads realm names from
+    `rt_realms`, and goip reads no config files.
+- **Both refusing isn't always agreement.** goip doesn't implement
+  multipath `nexthop`. On `nexthop via … dev d0 weight 257`, ip resolves
+  `d0` and then refuses the weight, while goip stops at `nexthop`. O5 first
+  counted these 3 rows as "same". A goip "not implemented" now makes the
+  row "refuses", whatever ip did.
+- **Tests:** `TestWsO5Compare`, `TestWsO5Lookups`, `TestWsO5Split`,
+  `TestWsO5Argv` and `TestWsO5GoldenDiff` are table tests on hand-built
+  inputs. They cover the
+  branches the corpus doesn't reach yet: every "differs" detail, a lookup
+  that differs in more than its mask, and a lookup after the write.
+- **Mutation:** 20 of 20 mutants killed, each by a relevant test (outcome
+  classification, the lookup split and comparison, the diff detail, the
+  golden comparison, `-6` parsing, and the three protocol limits). Two
+  needed a second try:
+  - "a rule's header length is wrong" first used `RtMsgSizeCst`, which is
+    equivalent, since `rtmsg` and `fib_rule_hdr` are both 12 bytes;
+  - "the golden file isn't compared" first survived, because a correct
+    report matches it. The comparison is now `wsO5GoldenDiff`, with its own
+    table test. That test found that a reordered or repeated line passed,
+    and the helper now reports it.
+
+##### W2d: rows mined from the fib selftests
+
+`nlcapgen kselftest` (`tools/nlcapgen/kselftest.go`) reads
+`fib_tests.sh`, `fib_nexthops.sh` and `fib_rule_tests.sh` from
+`tools/testing/selftests/net` in `~/Downloads/linux` (6b4b543fa187). It
+writes `nix/microvms/workbench/fib.rows.jsonl` and lists every line it
+skips, with the reason, in `fib.skipped.jsonl`.
+
+The miner is a static walker, not a shell:
+
+- **Groups:** each test the script's main loop runs (`$TESTS` or
+  `$ALL_TESTS`, through its `case` arms) is one group, with the script's
+  per-test prelude (`setup`) walked first.
+- **What it follows:** top-level and `local` assignments, `$1`–`${9}` in
+  inlined functions, `for` over a literal list or `$(seq [A] B)`, an
+  `if`'s then branch, `set -e`/`set +e`, `run_cmd "…"` and
+  `log_test $? N "msg"`.
+- **What it skips, and says so:** command substitutions, compound
+  commands, unresolved variables, other namespaces, `ip netns` (the
+  workbench gives every row its own), `else` branches, a then branch that
+  returns (a failure check), and a then branch whose condition reads an
+  earlier rc (`if [ $rc -eq 0 ]`).
+- **Rows:** each route, rule or nexthop command becomes a row. Its pre
+  steps are lib.sh's `rp_filter` sysctls, then every step of its group
+  before it. A step the selftest doesn't require to succeed is a
+  tolerated pre step.
+- **rc:** `log_test $? N` after the command gives the row rc N
+  (positive: for 0, negative: otherwise); `set -e` gives rc 0. Anything
+  else is a corner: row with no rc, which the corpus test still holds to
+  "an iproute2 or kernel refusal, never ack-then-fail".
+- **Namespaces:** `-netns` naming the test's own namespace is dropped.
+  `ip link … netns X` keeps the device here, and a later
+  `ip -netns X link set D up|down` for that device is kept too, since
+  some tests check what a peer's link state does to a nexthop.
+
+| space | rows | positive | negative | corner |
+|---|---|---|---|---|
+| fibt | 373 | 129 | 32 | 212 |
+| fibnh | 452 | 71 | 62 | 319 |
+| fibrule | 160 | 4 | 0 | 156 |
+
+Of the corner rows, 148 are commands whose output the selftest reads
+(`ip route get … | grep`), 188 follow a write the miner skipped, and 10
+use `dst_port`. 296 lines are skipped: 87 in other namespaces, 81 under a
+test of an earlier rc, 47 `ip netns`, 24 compound commands, 22 unresolved
+variables, and 35 others.
+
+**What recording showed (two fresh runs, 985 of 985 OK, the same message
+types and rcs in both):**
+
+- **The first run had 367 rows fail,** every one a miner bug. Each now has
+  a test row:
+  - `for i in 10 20 … 70;` with `do` on the next line kept the `;`
+    (`dummy_70;`);
+  - `$(seq 6)` (one argument) wasn't expanded, so `dummy4` never existed;
+  - `${1}` didn't expand, so `create_ns $me`'s sysctls were skipped as
+    another namespace. Among them is `keep_addr_on_down=1`, without which
+    `ip link set veth1 down` drops `2001:db8:91::1` for good, and the next
+    `nexthop … via 2001:db8:91::2` fails with "No route to host";
+  - `$NS_EXEC sysctl …` wasn't recognised as ip at all;
+  - `cmd 2>/dev/null || true` under `set -e` was taken as required;
+  - `if [ $rc -eq 0 ]; then ip rule del …` was walked after an add the
+    selftest expects to fail (276 rows).
+- **A step after a skipped write loses its rc.** `fib_rule_tests.sh`
+  deletes its rules by `pref $pref`, where `$pref` comes from
+  `$(ip rule show … | cut)`. The miner can't know it, so the rule stays,
+  and what the selftest states about later steps no longer holds. Those
+  188 rows are corner: rows, marked "follows line N, which the miner
+  skipped".
+- **The selftests are newer than the workbench's iproute2.** iproute2
+  7.2.0 predates `nexthop … dst_port` (ad2b2d95, after 7.2.0), so ip
+  refuses it before sending (rc 255) where the selftest expects the
+  kernel's rc 2. `ksNewer` lists such keywords with the commit; their rows
+  state no rc, and their pre steps are tolerated.
+
+**O5 over the mined rows.** O5 compares only write verbs (add, change,
+replace, prepend, append, del, delete), and resolves abbreviated objects
+(`ro`, `nex`) as goip does. Get, show, flush and bucket rows are counted
+as "not a write".
+
+| space | same | refuses | sends | differs | lookups differ | not a write |
+|---|---|---|---|---|---|---|
+| fibt | 127 | 103 | 0 | 0 | 44 | 143 |
+| fibnh | 316 | 86 | 0 | 0 | 151 | 50 |
+| fibrule | 72 | 0 | 0 | 0 | 4 | 88 |
+
+- **goip's writes match ip's on every mined row goip implements.** Every
+  lookup difference is the known `IFLA_EXT_MASK`.
+- **ip sends a byte of stack after a `congctl` name.** `ip route add …
+  congctl lock foo` first showed as 2 "differs" rows, differing in one
+  byte of `RTA_METRICS`: the pad after `RTAX_CC_ALGO "foo"` was 0xc4 and
+  0xe9 from ip, and 0 from goip. iproute2 builds the metrics in an
+  uninitialized `char mxbuf[256]` (`ip/iproute.c:1172`), and
+  `rta_addattr_l` doesn't clear the alignment padding
+  (`lib/libnetlink.c:1500-1505`). The kernel ignores padding, so nothing
+  breaks, but the byte changes from run to run. O5 now zeroes the padding
+  of `RTA_METRICS` sub-attributes before comparing, and counts the rows
+  where it wasn't zero (4).
+- **What goip refuses in the mined rows:** route `nhid` (73), multipath
+  `nexthop` (57), `expires` (25), `vrf` (15) and `dsfield` (5); nexthop
+  `dst_port` (10) and `encap` (4).
+- **Tests:** `TestMineScript` (43 rows), `TestMineScriptRowFields`,
+  `TestMineScriptPrelude`, `TestKsGroups`, `TestShLines`, `TestShWords`,
+  `TestIPObject` and `TestMineKselftests` cover the miner on small
+  scripts. `TestWsO5Applies`, the new `TestWsO5Argv` rows and
+  `TestWsO5ZeroMetricsPad` cover O5's side. `TestParseNexthopBucketCorpus`
+  now decodes 9 `RTM_GETNEXTHOPBUCKET` requests, up from 2: the mined rows
+  add three gets and four dumps.
+- **The miner leaves out iproute2's British-spelled alias for `neighbor`,**
+  which lint and the kernel-citation audit reject outside kernel paths. No
+  prefix of `neighbor` reaches it, and no mined selftest types it, so the
+  rows don't change.
+- **Mutation:** 29 of 29 miner mutants and 5 of 5 O5 mutants killed, each
+  by a relevant test. The first pass left four survivors, each fixed by
+  adding a test or removing dead code:
+  - a pipe reader that stays required, and a module taken from any word
+    rather than the one after `type`, each needed a test row;
+  - skip deduplication across groups needed `TestMineScriptPrelude`;
+  - `logTest`'s check for a step after a skipped write was dead code (such
+    a step never becomes the one `log_test` reads), so it was removed.
+- **Size:** the rows file is 2.2 MB, because each row repeats its group's
+  steps as pre steps (up to 124). The recorded rows add 6.6 MB of file
+  bytes to `ws/`, which then holds 13.4 MB, under the 20 MB budget. A run
+  of 985 rows takes about nine minutes at `-j 8`.
+
+#### Grammar matrix for addresses, neighbors and links (W3)
+
+W3 applies W2's method to `ip address`, `ip neigh` and `ip link`, one
+commit each: W3a addresses, W3b neighbors, W3c links.
+
+##### W3a: `ip address`
+
+`nlcapgen matrix -family addr -seed 1 -random 40` writes
+`nix/microvms/workbench/addr.rows.jsonl` from two spaces in
+`tools/nlcapgen/matrix_addr.go`. Each row runs in a fresh namespace
+holding one dummy device, `d0`, up with no address, so the address under
+test is the only one on it. A `change` or `del` first adds the address it
+works on.
+

+| addr4 | verb, local, peer, brd, label, scope, metric, lft, flags, proto | 132 | 1 | 12 | 87 | 32 |
+| addr6 | the same; brd, label and scope have only the values IPv6 ignores | 128 | 1 | 10 | 56 | 61 |
+
+Nearly every row takes at least one unusual spelling (`priority` for
+`metric`, `bro` for `broadcast`, `local` before the address), which makes
+it `corner:`.
+
+**What the kernel and iproute2 do** (each is a row, or a judged
+negative):
+
+- **ip exits 1, not 255, when `ipaddr_modify` returns -1.** `do_cmd`
+  negates the return value (`ip/ip.c:131`), so the checks after the device
+  lookup (`autojoin needs multicast address`, `valid_lft is zero`,
+  `preferred_lft is greater than valid_lft`) exit 1, as does IPv6's
+  `brd +`. Only `invarg()` exits 255.
+- **IPv4 `autojoin` with a peer is EINVAL.** `ip_mc_autojoin_config` joins
+  `ifa_address`, which a peer replaces, and `__ip_mc_join_group` refuses a
+  unicast group (`net/ipv4/igmp.c:2363`). A plain exclusion keeps the
+  pair out of positive rows; `Derive` writes the negative, since every
+  negative base row is unicast.
+- **Adding `0.0.0.0` succeeds and stores nothing.** `inet_rtm_newaddr`
+  returns 0 for a zero `IFA_LOCAL` (`net/ipv4/devinet.c:961`). O4 checks
+  that the dump doesn't hold it, and a delete of it is EADDRNOTAVAIL.
+- **IPv6 refuses a multicast address without `autojoin`, and the
+  unspecified one** (`ipv6_add_addr`, EADDRNOTAVAIL). `mngtmpaddr` needs a
+  prefix length of 64, and it is the peer's length that counts when there
+  is one (EINVAL, checked first).
+- **`nodad optimistic` is not refused while optimistic DAD is off.** The
+  kernel clears `IFA_F_OPTIMISTIC` before it checks the pair.
+- **IPv6 ignores `label`, `scope` and `broadcast`.** iproute2 sends them;
+  O4 compares them for IPv4 only. IPv6-only flags on an IPv4 address draw
+  a warning and aren't sent.
+- **An IPv4 delete without a prefix length is a wildcard deletion.**
+  ipaddr_modify leaves `IFA_ADDRESS` out, and the kernel matches on the
+  local address alone.
+
+The first run's 41 failures were all predictions of the first two kinds
+(rc 255 where ip exits 1, and `autojoin` with a peer). There were no
+command or capture bugs.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_addr_test.go`):
+
+- **O3** rebuilds the `AddrInfo` the request should parse to from the
+  row's axes, and checks the attribute set, each width and the header's
+  `ifa_flags`. The model covers: `brd +`/`-` computed from the peer or the
+  local address (none past /30, none on a delete), the wildcard deletion,
+  `default_scope`'s host scope for 127/8, and flags past 0xff moving to
+  `IFA_FLAGS` with the header 0. The index must be the one the kernel gave
+  `d0` in its answer to ip's lookup. O3 checked 213 requests.
+- **O4** looks for the address in `ip address show dev d0`'s dump after
+  each accepted write (167 rows): its addresses, prefix length, metric,
+  protocol and flags, plus the label, scope and broadcast address for
+  IPv4. After a delete, or a zero address, the dump must not hold it.
+- **O5:** goip sends the same request as ip on all 260 rows (addr4 132,
+  addr6 128). The only lookup difference is the known `IFLA_EXT_MASK`.
+- **Determinism:** a second run of all 260 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:** `TestAddrJudge` (16 rows), `TestBuildAddr`, `TestSpaceAssign`,
+`TestAddrCanDup`, `TestAddr4Exclusions` and `TestMatrixAddrRows` cover the
+generator. `TestAddrComputedBroadcast`, `TestAddrWantFromAxes`,
+`TestAddrRequestProblem` and `TestAddrDumpMatches` cover the oracles, and
+`TestWsO5HdrLen` covers O5's header lengths.
+
+**Mutation:** 27 of 27 mutants killed, each by a relevant test. The first
+pass left four survivors, each fixed by adding a test:
+
+- `addrCanDup` and the `autojoin`-with-a-peer negative weren't reached by
+  any row check, so each got a direct test;
+- an exclusion swapped for another wasn't visible in the rows, since no
+  positive row happened to take the pair. `TestAddr4Exclusions` now checks
+  the compiled space;
+- O5's header length for addresses was used only to describe a
+  difference, and no row differs. `TestWsO5HdrLen` checks it directly.
+
+**Size:** the rows add 771 KB of file bytes to `ws/`, 14.2 MB in all.
+
+##### W3b: `ip neigh`
+
+`nlcapgen matrix -family neigh -seed 1 -random 40` writes
+`nix/microvms/workbench/neigh.rows.jsonl` from two spaces in
+`tools/nlcapgen/matrix_neigh.go`. Each row runs in a fresh namespace
+holding a veth pair, `d0` and `d1`, both up, with 192.0.2.10/24 and
+2001:db8:1::10/64 on `d0`. A dummy device won't do here, since it is NOARP
+and resolves nothing. A `change` or `del` first adds the entry it works
+on, and a proxy row reads back `ip neigh show proxy`, since the plain dump
+leaves proxy entries out.
+
+| space | axes | rows | corner | negative |
+|---|---|---|---|---|
+| neigh4 | verb, dst (incl. broadcast, multicast, proxy), lladdr, nud, flags, protocol | 138 | 87 | 51 |
+| neigh6 | the same, with a link-local destination in place of broadcast | 137 | 82 | 55 |
+
+No row is plain `positive:`. The all-plain row (`add 192.0.2.1 dev d0`)
+has no link-layer address, so it is a judged negative, and every other row
+takes at least one corner value.
+
+**What the kernel does** (`net/core/neighbour.c` `neigh_add` and
+`__neigh_update`, each a row or a judged negative). All 275 rows passed
+on the first run.
+
+- **A new entry in a valid state needs a link-layer address**, or the
+  kernel refuses it with EINVAL ("No link layer address given"). That
+  includes the default state, NUD_PERMANENT, so `ip neigh add 192.0.2.1
+  dev d0` fails.
+- **Not for a multicast or broadcast destination.** `arp_constructor` and
+  `ndisc_constructor` start such an entry NUD_NOARP, which is valid, so
+  the kernel keeps the address it already has.
+- **`none`, `incomplete` and `failed` need no address.** They aren't
+  NUD_VALID, so `__neigh_update` stores the state and returns.
+- **`use` and `managed` return before that check.** `managed` also sets
+  the state to NUD_NONE, and it wins over a `nud` before it on the line.
+- **`extern_valid` needs a valid state** on a new entry (EINVAL, "Cannot
+  create externally validated neighbor with an invalid state").
+- **A proxy entry refuses `managed` and `extern_valid`** ("Invalid NTF_*
+  flag combination") and takes anything else. Added twice, it is found
+  rather than refused, so the duplicate-add negatives skip proxy rows.
+- **`change` of an absent entry is ENOENT.** change sends NLM_F_REPLACE
+  without NLM_F_CREATE. `Derive` writes three such rows (`chgone-*`).
+- **`router` is stored only with a valid state.** `__neigh_update` leaves
+  for an invalid state, `use` or `managed` before it updates
+  `NTF_ROUTER` (`net/core/neighbour.c:1460`), while `extern_learn` is set
+  earlier, by `neigh_update_flags`. O4 first expected the router flag on
+  8 such rows.
+
+**A parser gap closed.** `ParseNeigh` skipped `NDA_PROTOCOL`, which ip sends
+for `protocol` and the kernel dumps back. `NeighInfo` now has `Protocol`
+and `HasProtocol`, with table rows and `NdaProtocol` pinned at 12 next to
+`NdaFlagsExt`.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_neigh_test.go`):
+
+- **O3** rebuilds the `NeighInfo` the request should parse to: the state
+  (NUD_PERMANENT unless named), `NTF_PROXY`, `NDA_FLAGS_EXT` only when an
+  extended flag is set, and `NDA_PROTOCOL` only when named. The index must
+  be `d0`'s, found by name in the link dump ip reads first (`ll_init_map`),
+  where `lo` comes first. O3 checked 262 requests.
+- **O4** finds the entry in the dump after each accepted write (169 rows).
+  It checks the flags asked for, the extended flags and the protocol, plus
+  the state and link-layer address for a permanent or noarp entry, unless
+  `use` or `managed` handed the entry to the kernel to resolve. A
+  reachable entry may have gone stale by the readback, so other states
+  aren't compared.
+- **O5:** goip sends the same request as ip on all 275 rows (neigh4 138,
+  neigh6 137). ip neigh dumps every link before its write, and O5 used to
+  count that dump as a lookup goip skipped. `wsO5Split` now sets ip's
+  leading `NLM_F_DUMP` link requests apart and compares them with goip's
+  dumps byte for byte. They differ only in `IFLA_EXT_MASK`: 0x109 from ip,
+  0x1 from goip. iproute2 7.2.0's de91e928 added
+  `RTEXT_FILTER_SKIP_STATS | RTEXT_FILTER_NAME_ONLY` to `ll_init_map`'s
+  dump as well as to `ll_link_get`, and goip models 7.1. The report's mask
+  notes now say whether they come from a lookup or a dump.
+- **Determinism:** a second run of all 275 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:** `TestNeighJudge` (17 rows), `TestBuildNeigh`, `TestNeighCanDup`,
+`TestDeriveNeighChangeGone` and `TestMatrixNeighRows` cover the generator.
+`TestNeighWantFromAxes`, `TestNeighRequestProblem` and
+`TestNeighDumpMatches` cover the oracles. `TestWsO5Split`, `TestWsO5Lookups`
+and `TestWsO5MaskOnly` cover O5's dump handling.
+
+**Mutation:** 33 of 33 mutants killed, each by a relevant test. The first
+pass ran 35 and left three survivors:
+
+- the derive test didn't check that a proxy change was skipped, since
+  its proxy and plain sources had the same command. It now checks the
+  derived row's axes;
+- `managed` setting the state to NUD_NONE in the judge was dead code.
+  `flags` is one axis, so `managed` never meets `extern_valid`, and it was
+  removed;
+- judging a change's setup add as an add was equivalent to judging the
+  change itself, since the judge refuses one exactly when it refuses the
+  other. The line was removed. Neither removal changed the rows.
+
+**Size:** the rows add 707 KB of file bytes to `ws/`, 14.9 MB in all.
+
+##### W3c: `ip link set`
+
+`nlcapgen matrix -family link -seed 1 -random 40` writes
+`nix/microvms/workbench/link.rows.jsonl` from one space, `linkset`, in
+`tools/nlcapgen/matrix_link.go`. Each row runs in a fresh namespace
+holding one dummy device, `d0`, down, and runs `ip link set dev d0 …`. The
+readback dumps every link (`ip -d link show`), so a rename is still found.
+`ip link add`, kind by kind, is W3d.
+
+| axis | values (boundary values in bold) |
+|---|---|
+| updown | absent, up, down |
+| mtu | absent, 1400, **0**, **65535** |
+| txqlen | absent, 500, **0**, **32767** (`qlen`), `txq 100` |
+| group | absent, 5, `default`, **2147483647** |
+| alias | absent, `hello`, **255 characters** |
+| address | absent, a MAC, `addr` abbreviated, `broadcast` |
+| flag | absent, multicast on and off, promisc, allmulticast, arp off, dynamic, trailers off |
+| gso | absent, gso_max_size, gso_max_segs (**65535**), gro_max_size (**524280**), gso_ipv4_max_size, gro_ipv4_max_size |
+| mode | absent, `mode dormant`, `mode default`, `state dormant` |
+| name | absent, `name d9` |
+
+130 rows: 8 positive, 7 boundary, 105 corner and 10 negative. All 130
+passed on their first run, so every prediction about a dummy device held:
+
+- **A dummy has no MTU limits.** It sets `min_mtu` and `max_mtu` to 0
+  (`drivers/net/dummy.c:126`), so `mtu 0` and `mtu 65535` are taken.
+  `mtu -1` passes `get_integer` and the kernel refuses it as negative
+  (EINVAL, "mtu less than device minimum").
+- **`txqueuelen 32768` is ERANGE.** `ifla_policy` bounds `IFLA_TXQLEN` at
+  S16_MAX (`txqlen_range`), before `netif_change_tx_queue_len`'s own check.
+- **`gro_max_size 524281` is EINVAL** (past `GRO_MAX_SIZE`, 8 × 65535, in
+  `validate_linkmsg`). `gso_max_segs 65536` never reaches the kernel:
+  iplink_parse refuses it against `GSO_MAX_SEGS`.
+- **A multicast MAC is EADDRNOTAVAIL** (`eth_mac_addr`). A 2-byte address
+  is refused by iproute2 after it has looked d0's address length up
+  (`nl_get_ll_addr_len`), so it exits 1 with an acknowledged lookup.
+- **An alias of 256 characters is refused by iproute2** (`alias too long`,
+  IFALIASZ), and a name of 16 by `check_ifname`.
+
+**A parser gap closed.** `ParseNewLink` skipped `IFLA_IFALIAS`, ip's
+`alias` line. `LinkInfo` now has `IfAlias`. The kernel dumps it
+NUL-terminated and iproute2 sends it without the NUL; both decode alike.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_link_test.go`):
+
+- **O3** rebuilds every attribute's bytes from the axes and compares them,
+  in any order, with none missing, extra or repeated. It also checks the
+  `ifinfomsg`: AF_UNSPEC, d0's index, and `ifi_flags`/`ifi_change` from
+  up, down and the on/off flag (`arp off` and `trailers off` set
+  `IFF_NOARP` and `IFF_NOTRAILERS`). No `NLM_F_CREATE`. O3 checked 124
+  requests.
+- **O4** finds `d0` by index in the dump after each accepted write (120
+  rows), and checks its name, the flags under the change mask, MTU,
+  txqueuelen, group, the GSO and GRO limits, link mode, address,
+  broadcast and alias. The operational state isn't compared: a down
+  device's stays down whatever `state` asked for.
+- **O5:** `set` is now one of O5's write verbs, run through goip's `link`
+  object. goip sends the same request as ip on only 8 of the 130 rows.
+  The other 122 stop at a keyword goip recognizes but hasn't implemented,
+  counted by the first one each row reaches: `group` 61, `gso_max_segs`
+  16, `gro_max_size` 15, `gro_ipv4_max_size` 7, `gso_ipv4_max_size` 6,
+  `broadcast` 6, `gso_max_size` 5, `mode` 3, `state` 1, and the
+  address-length lookup 2. That is goip's to-do list for `ip link set`.
+  Implementing it is outside W3.
+- **Determinism:** a second run of all 130 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:** `TestBuildLinkSet` and `TestMatrixLinkRows` cover the
+generator. `TestLinkSetWantFromAxes`, `TestLinkSetRequestProblem` and
+`TestLinkDumpProblem` cover the oracles, and three `TestParseNewLink` rows
+cover `IfAlias`.
+
+**Mutation:** 25 of 25 mutants killed, each by a relevant test. One
+survived the first pass: the longest-alias test compared the command with
+the constant that built it, so shortening the constant changed both. It
+now spells out 255 characters itself.
+
+**Size:** the rows add 737 KB of file bytes to `ws/`, 15.6 MB in all. They
+are larger than W3a's and W3b's because every readback dumps both links
+with `-d`, and 1 in 5 rows carries the 255-character alias.
+
+##### W3d: `ip link add`
+
+The second space in `link.rows.jsonl`, `linkadd`
+(`tools/nlcapgen/matrix_linkadd.go`). The `linkset` rows come first and
+keep their ids, so W3c's captures are unchanged. Each row runs in a fresh
+namespace holding `d0`, a dummy that is up, as the lower device a vlan or
+macvlan names, and adds `n0`. The readback shows `n0` alone.
+
+| axis | values (boundary values in bold) |
+|---|---|
+| name | `n0`, `dev n0`, `name n0` |
+| up | absent, up |
+| mtu | absent, 1400, **1500**, 9000 |
+| txqlen | absent, 100, **0** |
+| address | absent, a MAC |
+| queues | absent, `numtxqueues 4`, `numrxqueues 4`, both |
+| kind | dummy; ifb; veth (`peer name p0`, and with the peer's mtu); vlan (`id 10`, **`id 4094`**, `protocol 802.1ad`); macvlan (`mode bridge`, `private`, `passthru`); bridge (and `stp_state 1`) |
+
+111 rows: 10 positive, 8 boundary, 74 corner and 19 negative. Three were
+wrong on the first run:
+
+- **A bare name of 16 characters is refused by the kernel.** A bare name is
+  iplink_parse's `dev`, which `check_altifname` allows up to ALTIFNAMSIZ,
+  so ip sends it and `ifla_policy` refuses `IFLA_IFNAME` (ERANGE). The
+  `name` keyword goes through `check_ifname`, which refuses it in ip
+  (W3c).
+- **`vlan id 65536` is refused after a lookup.** `vlan_parse_opt` runs after
+  iplink_parse has looked `d0` up, so ip exits 255 with an acknowledged
+  `RTM_GETLINK`.
+- **An unknown kind is ENOTSUP.** The kernel returns EOPNOTSUPP ("Unknown
+  device type"), which Linux numbers the same as ENOTSUP, and that is the
+  name `unix.ErrnoName` gives it.
+
+The rest held:
+
+- **A vlan's or macvlan's MTU may not pass its lower device's** (1500 on
+  `d0`, EINVAL). A veth, bridge, dummy or ifb takes 9000.
+- **VLAN id 4095 is ERANGE**, and 4094 is the largest taken.
+- **A vlan with no lower device is EINVAL.**
+- **Adding `n0` twice is EEXIST** (three `dup-*` rows).
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_link_test.go`):
+
+- **O3** checks the top-level attributes by bytes, with `IFLA_LINK` as
+  `d0`'s index, plus the `IFLA_LINKINFO` nest byte for byte:
+  `IFLA_INFO_KIND` with its NUL, then the kind's `IFLA_INFO_DATA`. The
+  model covers:
+  - a veth peer: a zeroed `ifinfomsg`, with the peer's `IFLA_MTU` before
+    its `IFLA_IFNAME`, as the peer's iplink_parse adds them;
+  - a vlan protocol in network order before a host-order id;
+  - a macvlan mode as a u32;
+  - a bridge option.
+
+  It also checks `NLM_F_CREATE|NLM_F_EXCL` and index 0. O3 checked 109
+  requests.
+- **O4** finds `n0` in the dump (92 rows) and checks its kind, up, lower
+  device, MTU, txqueuelen, queue counts and address. It also checks the
+  decoded kind data: a vlan's id and protocol (802.1Q when none is named),
+  a macvlan's mode and a bridge's STP state.
+- **Two findings from O4:**
+  - `ip link show dev n0` first resolves the name, and iproute2 7.2.0
+    asks with `RTEXT_FILTER_NAME_ONLY`, so the first reply about `n0`
+    holds its name alone. The full reply comes second, and O4 takes the
+    last.
+  - A passthru macvlan takes its lower device's address whatever was
+    asked (`eth_hw_addr_inherit`, `drivers/net/macvlan.c:1552`), so its
+    address isn't compared.
+- **O5:** goip sends the same request as ip on 43 rows, across all six
+  kinds. The other 68 stop at `numtxqueues` (47) or `numrxqueues` (21),
+  which goip hasn't implemented. Every lookup difference is the known
+  `IFLA_EXT_MASK`.
+- **Determinism:** a second run of all 111 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:** `TestLinkAddJudge`, `TestBuildLinkAdd`, `TestDeriveLinkAddDup`
+and `TestMatrixLinkAddRows` cover the generator. `TestLinkAddInfoData`,
+`TestLinkAddRequestProblem` and `TestLinkAddDumpProblem` cover the
+oracles.
+
+**Mutation:** 23 of 23 mutants killed, each by a relevant test. Two
+mutants were rewritten before they counted, neither a survivor:
+
+- "queue counts unchecked in the dump" first panicked on rows with no
+  queue count. It now drops the check, and `TestLinkAddDumpProblem` gained
+  a tx-queue row to kill it;
+- "a passthru address compared" first didn't build.
+
+**Size:** the rows add 321 KB of file bytes to `ws/`, 16.0 MB in all,
+against the 20 MB budget.
+
+#### Netlink coverage report (W4)
+
+`nlcapgen coverage -linux DIR -ws DIR -out FILE` (`tools/nlcapgen/coverage.go`)
+writes [`ws-coverage.txt`](ws-coverage.txt). For each message family the
+rows write, it lists which attributes of the kernel's policy table some
+request in the workbench corpus sent. That is every row's `ip.pcap`: 4106
+captures. The never-sent list is the to-do list for the next axis values.
+
+- **The policy** is the set of designators in the `nla_policy` table, read
+  from the Linux tree: `rtm_ipv4_policy`, `rtm_ipv6_policy`,
+  `fib_rule_policy`, `rtm_nh_policy_new`, `ifa_ipv4_policy`,
+  `ifa_ipv6_policy`, `nda_policy` and `ifla_policy`. The UNSPEC entry
+  holds only `strict_start_type`, so it isn't counted.
+- **Attribute numbers** come from the uapi enum: its place in the enum, or
+  an explicit value.
+- **The requests counted** are every type whose kernel handler parses with
+  that table. The route, address, link and neighbor tables also judge
+  their family's gets and dumps (`inet_rtm_getroute`, the address dump
+  checks, `rtnl_getlink`, the neighbor get and dump checks). The rule and
+  new-nexthop tables judge only writes.
+- Route and address requests are split by family, so an `AF_UNSPEC`
+  address dump counts for neither.
+
+| family | sent / policy | requests | never sent, though ip has a keyword for it | never sent, and no iproute2 code sends it |
+|---|---|---|---|---|
+| route4 | 12 / 19 | 494 | `RTA_FLOW` (realms), `RTA_ENCAP`/`_TYPE` (encap), `RTA_UID`, `RTA_IP_PROTO`, `RTA_SPORT`, `RTA_DPORT` (route get) | — |
+| route6 | 12 / 19 | 461 | `RTA_ENCAP`/`_TYPE`, `RTA_UID`, `RTA_IP_PROTO`, `RTA_SPORT`, `RTA_DPORT`, `RTA_FLOWLABEL` (route get) | — |
+| rule | 23 / 23 | 464 | — | — |
+| nexthop | 11 / 12 | 494 | `NHA_DST_PORT`, which iproute2 7.2.0 predates (W2d) | — |
+| addr4, addr6 | 8 / 9, 6 / 7 | 110, 103 | — | `IFA_TARGET_NETNSID` |
+| neigh | 4 / 13 | 262 | `NDA_IFINDEX`, `NDA_MASTER` (neigh dump filters); `NDA_VLAN`, `NDA_PORT`, `NDA_VNI`, `NDA_NH_ID`, `NDA_FDB_EXT_ATTRS` (`bridge fdb`, W5) | `NDA_CACHEINFO`, `NDA_PROBES` |
+| link | 19 / 56 | 2548 | `IFLA_MASTER`, `IFLA_AF_SPEC` (addrgenmode), `IFLA_NET_NS_FD`, `IFLA_CARRIER`, `IFLA_LINK_NETNSID`, `IFLA_PROTO_DOWN` and `_REASON`, `IFLA_XDP`, `IFLA_TARGET_NETNSID`, `IFLA_NEW_IFINDEX`, `IFLA_PROP_LIST`/`IFLA_ALT_IFNAME` (altname), `IFLA_PARENT_DEV_NAME`, `IFLA_VFINFO_LIST` | 23, mostly ones the kernel only reports (`IFLA_PROMISCUITY`, the carrier counters, `IFLA_MIN_MTU`/`MAX_MTU`, `IFLA_PERM_ADDRESS`, `IFLA_TSO_MAX_*`, …), plus `IFLA_MAP`, `IFLA_WEIGHT`, `IFLA_NET_NS_PID`, `IFLA_VF_PORTS`, `IFLA_PORT_SELF` and `IFLA_PACING_OFFLOAD`, which the kernel takes and iproute2 7.2.0 has no keyword for |
+
+Whether ip has a keyword was checked by searching iproute2's `ip/`, `lib/`
+and `bridge/` for each name where an attribute is added. A plain
+line-by-line search for `addattr…(…NAME` missed four that are added over
+two lines or through a helper: `RTA_ENCAP` (via `rta_nest`),
+`IFLA_PROP_LIST`, `IFLA_PROTO_DOWN_REASON` and `IFLA_VFINFO_LIST`.
+
+**What the report showed besides the gaps** ("sent outside the policy",
+each checked against the kernel source):
+
+- **`rtm_ipv4_policy` has no `RTA_VIA`**, and `rtm_ipv6_policy` no `RTA_DST`
+  or `RTA_SRC`. The kernel reads them without policy validation
+  (`fib_gw_from_via`; `rtm_to_fib6_config` copies the prefixes itself).
+- **`fib_rule_policy` has no `FRA_DST` or `FRA_SRC`.** Each family's
+  `configure` hook checks them.
+- **ip sends `IFA_LABEL` and `IFA_BROADCAST` on IPv6**, which
+  `ifa_ipv6_policy` doesn't name and the kernel ignores (W3a).
+- **IPv6 requests carry `RTA_CACHEINFO`.** These are `ip -6 route flush`'s
+  deletes, which echo back the dumped routes' attributes, cache info
+  included (18 mined fib rows).
+
+**Tests:** `TestUapiEnum`, `TestPolicyNames`, `TestFindPolicy`,
+`TestLoadPolicies`, `TestCovTally` and `TestWriteCoverage`, on fixture
+trees and hand-built messages, since the Linux tree isn't available to the
+hermetic tests.
+
+**Mutation:** 16 of 16 mutants killed, each by a relevant test. One
+survived the first pass: every test attribute was 8 bytes long, so
+dropping the walk's alignment to four bytes changed nothing.
+`TestCovTally` now has an odd-length attribute followed by another.
+
+Next is W4b: rows for the keywords in the table's fourth column.
+
+##### W4b: `ip route get`, for the route attributes no write sends
+
+Four of route4's seven gaps and five of route6's seven are lookup
+attributes. `nlcapgen matrix -family routeget -seed 1 -random 40` writes
+`nix/microvms/workbench/routeget.rows.jsonl` from two spaces in
+`tools/nlcapgen/matrix_routeget.go`. Each row runs `routeSetup`'s namespace
+plus a default route per family, so every destination resolves. There is
+no readback: the answer is in ip's own capture.
+
+| axis | values (boundary values in bold) |
+|---|---|
+| dst | connected, via the default route, **/32** or **/128**, `to` |
+| from | absent, d0's address |
+| dev | absent, `oif d0`, `dev d0` |
+| mark | absent, 0x10, **0** (ip sends no `RTA_MARK`), **4294967295** |
+| uid | absent, 1000, **0** |
+| ipproto | absent, tcp, udp, the family's ICMP |
+| ports | absent, sport, dport, both, **dport 65535** |
+| tos (v4) / flowlabel (v6) | absent, 0x10 or `dsfield 0x08` / 0x12345, **0xfffff** |
+| flags | absent, fibmatch, notify (v4) |
+
+161 rows (routeget4 81, routeget6 80): 7 positive, 42 boundary, 101 corner
+and 11 negative. The first run's 55 failures were two kernel rules the
+spaces hadn't modeled:
+
+- **Only TCP, UDP and the family's own ICMP are taken.**
+  `rtm_getroute_parse_ip_proto` (`net/ipv4/netlink.c`) refuses anything
+  else with EOPNOTSUPP ("Unsupported ip proto"), including ICMP in an IPv6
+  lookup and ICMPv6 in an IPv4 one. These are now bad values.
+- **An IPv6 lookup takes `RTM_F_FIB_MATCH` alone.**
+  `inet6_rtm_valid_getroute_req` refuses `notify` (EINVAL, "Invalid flags
+  for get route request"). That is the strict check, so ip enables strict
+  checking for gets. A device ip can't resolve is refused in its
+  `RTM_GETLINK` (ENODEV), before any lookup is sent.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_routeget_test.go`):
+
+- **O3** rebuilds the lookup: the `rtmsg`, with dst and src lengths at
+  full width, `RTM_F_LOOKUP_TABLE` on IPv4, plus fibmatch and notify. Then
+  every attribute's bytes. The ports and flow label are network order
+  (`get_be16`/`get_be32`), the mark and uid host order, `RTA_MARK` absent
+  for mark 0, and `RTA_OIF` as d0's index. `x/sys/unix` has no
+  `RTA_FLOWLABEL`, so the test names it as `RtaNhID + 1`. O3 checked 154
+  lookups.
+- **O4** holds the kernel's answer (150 rows). It must leave through
+  `d0`. Without fibmatch it is the destination at full length; with it,
+  the FIB entry that matched, which is shorter and holds the destination,
+  or the default route with no `RTA_DST`.
+- **O5 doesn't apply:** a lookup isn't a write.
+- **Coverage:** route4 rises from 12/19 to 16/19 and route6 from 12/19 to
+  17/19. What remains is `RTA_FLOW` (realms) and `RTA_ENCAP`/`_TYPE`,
+  which belong in the route write spaces. Adding values there regenerates
+  every route row, so it is left for its own step.
+- **Determinism:** a second run of all 161 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:** `TestBuildRouteGet` and `TestMatrixRouteGetRows` cover the
+generator. `TestRouteGetWantFromAxes`, `TestRouteGetRequestProblem`,
+`TestRouteGetReplyProblem` and `TestPrefixHolds` cover the oracles.
+
+**Mutation:** 17 of 17 mutants killed, each by a relevant test. Two
+survived the first pass:
+
+- the setup test compared the setup with the constant that built it, so
+  dropping the default routes went unseen. It now names them;
+- no prefix test cut through a byte where the byte and the bits disagree.
+  `TestPrefixHolds` now has a /20 holding 192.0.31.9.
+
+**Size:** the rows add 267 KB of file bytes to `ws/`, 16.2 MB in all.
+
+**Budget raised to 64 MB (2026-11-01):** at 16.2 MB of 20 MB, the corpus
+had room for about one more W3-sized family, and W5 adds five. The budget
+in `TestWsSizeBudget` is now 64 MB per kernel version. Each version has its
+own `ws/`, so W7's replays don't count against it. Packing a family into
+one pcapng stays the fallback if a version nears the new limit.
+
+##### W4c: the link keywords no row sent
+
+The link family's fourth-column gaps. `nlcapgen matrix -family linkattr
+-seed 1 -random 20` writes `nix/microvms/workbench/linkattr.rows.jsonl`
+from three spaces in `tools/nlcapgen/matrix_linkattr.go`:
+
+| space | device | axes (boundary values in bold) |
+|---|---|---|
+| linkattr | `d0`, with a bridge `br0` and a VRF `v0` | master: `master br0`, `vrf v0`, `nomaster`; addrgenmode: eui64, none, random; carrier on/off; netns: `netns $$`, `netns $$ index 100`; xdp: `xdp off`, `xdpgeneric none`, `xdpdrv off` (always last) |
+| linkpd | a macvlan `m0` (a dummy has no `change_proto_down`) | protodown on/off; `protodown_reason` 0 on, 0 off, **31 on**; up |
+| linkprop | `d0` | `ip link property add`/`del`, and `ip link show` by altname; altname: short, 16 characters, **127 characters**, two at once, one with a slash; `dev d0` or bare `d0` |
+
+100 rows (linkattr 52, linkprop 28, linkpd 20): 18 positive, 5 boundary,
+59 corner and 18 negative. Two are derived:
+
+- `linkattr/xdp-not-last` has `xdp off carrier on`;
+- `linkattr/parentdev` is `ip link set dev d0 parentdev br0`. iplink_parse sends
+  `IFLA_PARENT_DEV_NAME` on a set too, and the kernel only ever dumps it
+  (`rtnl_fill_ifinfo`), so the set succeeds and changes nothing.
+
+`linkprop/del-absent` (ENOENT) and `linkprop/dup-1` (EEXIST) are derived
+too.
+
+The first runs' failures were all iproute2 parsing rules the spaces
+hadn't modeled:
+
+- **`xdp off` must be the last argument.** Otherwise `xdp_parse` hands
+  `off` to `bpf_parse_and_load_common` as a program mode (`What mode is
+  "off"?`).
+- **`carrier`/`protodown` with a bad value exit 22.** That is
+  `parse_on_off`'s -EINVAL, not the usual 255.
+- **`index` needs `netns`** (rc 255, "index can be used only when creating
+  devices or when moving device to another netns").
+- **The kernel decides the rest:**
+  - `xdpdrv off` on a dummy succeeds;
+  - a slash in an altname is taken (`netdev_name_node_alt_create`);
+  - `master nosuch` is ip's lookup refused with ENODEV;
+  - `protodown on` on a dummy gives EOPNOTSUPP;
+  - `protodown off` with a reason on gives EBUSY (`do_set_proto_down`,
+    "Cannot clear protodown, active reasons").
+
+**Two iproute2 print bugs** turned up in `ip -d link show` (`print_proto_down`,
+`ip/ipaddress.c`). Both are recorded here only:
+
+- **The reason is read with `rta_getattr_u8`**, though
+  `IFLA_PROTO_DOWN_REASON_VALUE` is a u32. Reasons 8–31 never print: the
+  `31 on` rows show no `protodown_reason`, while O4 finds 0x80000000 in
+  the kernel's dump.
+- **No space precedes `protodown_reason <…>`**, so it runs into the
+  address before it (`brd ff:ff:ff:ff:ff:ffprotodown_reason <0>`).
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_linkattr_test.go`):
+
+- **O3 for linkattr and linkpd** extends the W3c set model with:
+  - `IFLA_MASTER` as the looked-up index, 0 for `nomaster`;
+  - `IFLA_CARRIER` and `IFLA_PROTO_DOWN` as u8;
+  - `IFLA_NEW_IFINDEX`, `IFLA_LINK_NETNSID` and the
+    `IFLA_PARENT_DEV_NAME` string;
+  - the nests: addrgenmode in `IFLA_AF_SPEC`'s `AF_INET6`, `IFLA_XDP`'s fd
+    −1 and flags, and the reason's mask and value;
+  - the namespace fd `netns $$` opened, taken from the request (any
+    descriptor past stderr).
+
+  It checked 63 requests.
+- **O4 for linkattr and linkpd** holds the dumped device's master,
+  addrgenmode and carrier, and its protodown and reason, which are 0 when
+  not asked for. `ip link show dev m0` first looks m0 up and gets a
+  name-only answer, so the last reply about the device is the one read.
+  It checked 57 round trips.
+- **O3 for linkprop:**
+  - an add carries `NLM_F_EXCL|NLM_F_CREATE|NLM_F_APPEND`;
+  - the names are NUL-terminated `IFLA_ALT_IFNAME`s in `IFLA_PROP_LIST`;
+  - a show sends two `RTM_GETLINK`s naming the device by `IFLA_IFNAME`,
+    or by `IFLA_ALT_IFNAME` when `check_ifname` refuses the name (16 or
+    more characters, a slash or space, `.` or `..`). The second one has
+    `AF_PACKET` and no index.
+
+  It checked 27 requests.
+- **O4 for linkprop:** after an add or show, d0 holds every name; after a
+  del, none. It checked 24 round trips.
+- **O5:**
+  - linkattr has 2 same and 50 refused;
+  - linkpd has 1 same and 19 refused. goip has none of these keywords,
+    which adds addrgenmode, vrf, protodown and its reason, carrier, xdp,
+    netns, index, link-netnsid and parentdev to its list;
+  - linkprop has 19 same: goip's altname writes match ip's, and the 9
+    shows aren't writes.
+- **Coverage:** link rises from 19/56 to 31/56 (`ws-coverage.txt`). The
+  tally now counts `RTM_NEWLINKPROP` and `RTM_DELLINKPROP` as link
+  requests, since `rtnl_linkprop` parses them with `ifla_policy`. Of the
+  25 left, iproute2 7.2.0 sends only two:
+  - `IFLA_TARGET_NETNSID`, from `link-netnsid` with `link`, which needs a
+    peer namespace with an nsid;
+  - `IFLA_VFINFO_LIST` (`vf`, W5's netdevsim).
+
+  It never sends `IFLA_NET_NS_PID`: `netns_get_fd` turns a pid into
+  `/proc/PID/ns/net` and sends the fd.
+- **Determinism:** a second run of all 100 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:**
+
+- The generator: `TestBuildLinkAttr`, `TestDeriveLinkAttrCorners`,
+  `TestLinkAttrSetups`, `TestLinkPDJudge`, `TestBuildLinkPD`,
+  `TestBuildLinkProp`, `TestDeriveLinkPropAbsent` and
+  `TestMatrixLinkAttrRows`.
+- The oracles: `TestLinkAttrWantFromAxes`, `TestLinkNetnsFD`,
+  `TestLinkProtoDown`, `TestLinkAttrDumpProblem`, `TestLinkPropAlts`,
+  `TestLinkPropRequestProblem`, `TestLinkShowNameAttr`,
+  `TestLinkShowProblem` and `TestLinkPropDumpProblem`.
+
+**Mutation:** 30 of 30 mutants killed, each by a relevant test. Four
+survived the first pass, and each now has a row:
+
+- no generator test looked at reason 31's mask;
+- no O4 row had a carrier that was present but wrong;
+- no show row had three requests;
+- `TestWsO5HdrLen` lacked the property types. Their bodies match byte for
+  byte, so comparing them whole hid the missing header length.
+
+**Size:** the rows add 644 KB to `ws/`, 16.9 MB of 64 MB in all.
+
+##### W5a: `bridge fdb`
+
+W4's report counted no `AF_BRIDGE` neighbor writes: `ip neigh` never
+sends `NDA_VLAN`, `NDA_PORT`, `NDA_VNI`, `NDA_IFINDEX`, `NDA_SRC_VNI`,
+`NDA_NH_ID` or `NDA_FDB_EXT_ATTRS`, and `bridge fdb` sends all of them.
+`nlcapgen matrix -family fdb -seed 1 -random 40` writes
+`nix/microvms/workbench/fdb.rows.jsonl` from two spaces in
+`tools/nlcapgen/matrix_fdb.go`:
+
+| space | devices | axes (boundary values in bold) |
+|---|---|---|
+| fdbbr | a VLAN-filtering bridge `br0` with a dummy port `d0`, VLAN 10 on both | verb: add, append, replace, del; MAC: unicast, unicast after `to`, multicast, zero; dev: port or bridge; `self`, `master`, both or neither; state: none, permanent, static, dynamic, local, temp; sticky, extern_learn, use, router; vlan: none, 1, 10, **4094**, 65535; `activity_notify`, `norefresh`, `activity_notify inactive`, `inactive` alone |
+| fdbvx | a VXLAN `vx0` (VNI 100, port 4789, nolearning) over `d1`, with nexthops 1 (fdb), 10 (an fdb group of 1) and 2 (not fdb) | remote: `dst` v4 or v6, `nhid` 10, 1, 2 or 99, none; port: none, 4790, **0**, **65535**, `0x12b6`; vni: none, 200, **0**, **16777215**; src_vni: none, 100, 300; `via d1`; state |
+
+199 rows (fdbbr 99, fdbvx 100): 3 positive, 6 boundary, 34 corner and
+156 negative. A del's pre step is its own add, when that add would be
+accepted. Derived rows add a duplicate add (EEXIST), a delete of
+something absent (ENOENT) and the two `twice-*` rows below.
+
+**bridge, unlike ip:**
+
+- **It exits 255 on a kernel refusal**, since `fdb_modify` returns -1.
+- **Every command dumps links first** (`ll_init_map`, `bridge/fdb.c:948`),
+  so a refused argument is `ack-then-fail`, never zero messages. An
+  unknown `dev` or `via` is the kernel's ENODEV to `ll_link_get`.
+- **`fdb_modify`'s defaults:**
+  - with neither `self` nor `master` it sets `NTF_SELF`;
+  - the state starts at `NUD_NOARP`, so no keyword means permanent (192),
+    `static` is 66 and `dynamic` is 2;
+  - `vlan` is `atoi` into a short and is sent only if not negative, so
+    `vlan 65535` sends nothing and `vlan ten` sends VLAN 0;
+  - `port 0` isn't sent;
+  - `nhid` is checked against `dst`, `port` and `vni` only, so `via` with
+    `nhid` reaches the kernel (EINVAL).
+
+**The kernel:** `rtnl_fdb_add` and `rtnl_fdb_del` parse with a NULL
+policy (`net/core/rtnetlink.c:4822` and `4936`). They refuse VLAN 0 and
+4095 (EINVAL). With neither path taken the answer is EOPNOTSUPP, which
+Go names ENOTSUP, as the rows do. The paths are:
+
+- `master` on a bridge port, which is `br_fdb_add`. It refuses (EINVAL)
+  the zero MAC, a VLAN the port lacks, `use` or a non-permanent entry
+  towards the bridge, sticky with permanent, and `inactive` without
+  `activity_notify`;
+- `self` on the dummy, which is `ndo_dflt_fdb_add`. It takes only
+  permanent entries and no VLAN;
+- the VXLAN's `vxlan_fdb_add`. It refuses (EINVAL):
+  - no `dst` and no `nhid`;
+  - `nhid` with anything else;
+  - a dynamic `nhid`;
+  - an `nhid` that is missing, not fdb or not a group.
+
+  An IPv6 `dst` on the IPv4 VXLAN is EAFNOSUPPORT, and a replace of a
+  multicast or zero MAC is EOPNOTSUPP.
+
+**A kernel quirk** (recorded here only):
+
+- `vxlan_fdb_alloc` keys an entry by its `src_vni`, but on a VXLAN
+  without `external` (`VXLAN_F_COLLECT_METADATA`), `vxlan_find_mac_rcu`
+  always looks up under the device's own VNI
+  (`drivers/net/vxlan/vxlan_core.c`).
+- So an entry added with a foreign `src_vni 300` can't be found:
+  - its delete is ENOENT (the del rows with `src_vni 300` expect that);
+  - a second identical replace finds nothing, inserts the same key
+    again, and the hash refuses it with EEXIST (`fdbvx/twice-other`). The
+    same pair under the device's own VNI succeeds (`fdbvx/twice-own`);
+  - the dump still lists the entry, without its `src_vni`.
+
+**Oracles** (`pkg/xtcpnl/xtcpnl_ws_fdb_test.go`):
+
+- **ParseNeigh** now decodes `NDA_PORT` (big-endian), `NDA_VNI`,
+  `NDA_SRC_VNI`, `NDA_IFINDEX`, `NDA_NH_ID` and `NDA_FDB_EXT_ATTRS`'s
+  `NFEA_ACTIVITY_NOTIFY` and `NFEA_DONT_REFRESH`. A short attribute is
+  skipped, and so is a nest that overruns. A repeated attribute's last
+  copy wins.
+- **O3:**
+  - the request has `AF_BRIDGE`, the looked-up index, the state and
+    flags;
+  - its attributes are in `fdb_modify`'s order, at their widths;
+  - the decoded values equal the axes.
+
+  An `ack-then-fail` row must send no fdb request. O3 checked 190
+  requests.
+- **O4:** after an accepted add, the device's dump has the entry
+  (MAC, VLAN and, on vx0, the dst, nhid, port, VNI and via); after a
+  del, it is gone. A port of 4789 or VNI of 100 is the device's own,
+  which the dump leaves out. O4 checked 43 round trips.
+- **O5 doesn't apply:** goip implements `ip`, not `bridge`.
+- **Coverage:** no policy judges these writes, so `nlcapgen coverage`
+  counts them on a line of their own (190 requests) rather than as
+  neigh, which stays at 4/13. The `NDA_*` attributes above are sent
+  only by these writes.
+- **Determinism:** a second run of all 199 rows, on the same workbench
+  boot, gave the same status, rc and message types on every row.
+
+**Tests:**
+
+- The generator: `TestFdbBrJudge`, `TestFdbVxJudge`, `TestBuildFdb`,
+  `TestFdbVxTwice`, `TestDeriveFdbDupGone`, `TestMatrixFdbRows`, and new
+  `TestCovTally` and `TestWriteCoverage` rows.
+- The oracles: `TestFdbWantFromAxes`, `TestFdbRequestProblem`,
+  `TestFdbDumpHas`, `TestFdbAckFailProblem`, `TestFdbRoundTripProblem`,
+  and seven new `TestParseNeigh` rows.
+
+**Mutation:** 29 of 29 mutants killed, each by a relevant test. Three
+survived the first pass:
+
+- **ParseNeigh kept the first `NFEA_ACTIVITY_NOTIFY`**, where
+  `nla_parse` and `parse_rtattr` keep the last. It now keeps the last,
+  and a row repeats the attribute.
+- **No hand-built row broke two oracle checks:** the `ack-then-fail`
+  check, and O4's presence check. Each is now a function with its own
+  table (`TestFdbAckFailProblem`, `TestFdbRoundTripProblem`).
+
+Two mutants that didn't compile were rewritten and rerun.
+
+**Size:** the rows add 563 KB to `ws/`, 17 MB of 64 MB in all.
+
+##### W5b: `bridge mdb`
+
+W4's report covered no MDB writes. `bridge mdb` is the only iproute2
+command that sends `RTM_NEWMDB` or `RTM_DELMDB`, and the only one that
+dumps with `RTM_GETMDB`. `nlcapgen matrix -family mdb -seed 1 -random 40`
+writes `nix/microvms/workbench/mdb.rows.jsonl` from two spaces in
+`tools/nlcapgen/matrix_mdb.go`:
+
+| space | devices | axes (boundary values in bold) |
+|---|---|---|
+| mdbbr | a VLAN-filtering bridge `br0` with a dummy port `d0`, VLAN 10 on both; a lone dummy `d9`; a second bridge `br1` with port `d2` | verb: add, replace, del; port: `d0` or `br0` (a host join); group: IPv4, IPv6, L2; state: none, permanent, temp; vid: none, 1, 10, **4094**; src: none, IPv4, IPv6; filter_mode: none, exclude, include; source_list: none, one, two; proto: none, static, bgp, 200 |
+| mdbvx | a VXLAN `vx0` (VNI 100, port 4789, nolearning) over `d1` (192.0.2.10/24) | verb; group: IPv4, 0.0.0.0, IPv6, `::`; state: permanent or none; dst: IPv4, IPv6, none; dst_port: none, 4790, **0**, **65535**; vni: none, 200, **0**, **16777215**; src_vni: none, 100, 300; `via d1`; src; filter_mode; source_list; proto |
+
+177 rows (mdbbr 90, mdbvx 87): 5 positive, 6 boundary, 18 corner and
+148 negative. As in W5a, a del's pre step is its own add, when that add
+would be accepted. Derived rows add a duplicate add (EEXIST), a delete of
+something absent (EINVAL on the bridge, ENOENT on the VXLAN) and
+`mdbbr/del-all-vlans` (below).
+
+**bridge's side** (`bridge/mdb.c` `mdb_modify`):
+
+- add is `NLM_F_CREATE|NLM_F_EXCL`, replace `NLM_F_CREATE|NLM_F_REPLACE`,
+  and del is `RTM_DELMDB` with no flags.
+- `MDBA_SET_ENTRY` is a 28-byte `struct br_mdb_entry` after an 8-byte
+  `struct br_port_msg`. `permanent` reaches the state only on
+  `RTM_NEWMDB`. The VLAN is `atoi` into a short and always sent, so
+  `vid 65535` is sent as 65535.
+- `MDBA_SET_ENTRY_ATTRS` is sent iff any of src, filter_mode,
+  source_list, proto, dst, dst_port, vni, src_vni or via is given. Its
+  attributes come in that order. `dst_port` is a host-order u16, and
+  `dst_port 0` is sent. The VNI isn't range-checked, so `vni 16777216`
+  reaches the kernel, which answers ERANGE.
+- As in `bridge fdb`, the links are dumped first (`ll_init_map`), so a
+  refused argument is `ack-then-fail` and exits 255.
+
+**The kernel:**
+
+- `rtnl_validate_mdb_entry` (`net/core/rtnetlink.c`, policy
+  `mdba_policy`) refuses (EINVAL):
+  - a zero port index;
+  - an IPv4 group that is neither multicast nor 0.0.0.0, or that is local
+    multicast;
+  - `ff02::1`;
+  - an L2 group that isn't multicast;
+  - a state other than 0 or 1;
+  - VLAN 4095 or more.
+
+  A device without `ndo_mdb_add`, such as a dummy, is EOPNOTSUPP.
+  `proto kernel` is under the policy's minimum (ERANGE).
+- **The bridge** (`net/bridge/br_mdb.c`, `br_mdb_config_init` and
+  `br_mdb_config_attrs_init`) refuses (EINVAL):
+  - a port that isn't one of its own;
+  - the 0.0.0.0 group;
+  - a source of the wrong family, or on an L2 group;
+  - a filter mode or source list on a host group or on an entry that is
+    no (*, G);
+  - a source list without a filter mode;
+  - INCLUDE with an empty list;
+  - a protocol on a host group.
+
+  `br_mdb_add` then refuses flags on a host group, a host join with a
+  source, and an L2 entry that isn't permanent. A VLAN the port lacks
+  (4094) is taken as given.
+- **The VXLAN** (`drivers/net/vxlan/vxlan_mdb.c`) refuses (EINVAL):
+  - a port other than itself;
+  - an add or replace that isn't permanent;
+  - a VLAN;
+  - a missing `dst`;
+  - a source on the all-zeros group;
+  - a filter mode or source list on an (S, G) entry;
+  - a source list without a mode;
+  - INCLUDE with an empty list.
+
+  It takes the 0.0.0.0 and `::` groups, its catch-all. A delete that
+  finds nothing is ENOENT; a duplicate add is EEXIST.
+
+**A kernel quirk** (recorded here only): on a VLAN-filtering bridge, a
+delete without a VLAN loops over the port's VLANs, and `br_mdb_del`
+returns the last one's result. After an add in VLAN 1 only, a delete
+with no VLAN removes that entry but reports VLAN 10's EINVAL
+(`mdbbr/del-all-vlans`).
+
+**Dumps differ by device:**
+
+- The bridge answers a dump with `RTM_GETMDB`
+  (`net/bridge/br_mdb.c:391`), and the VXLAN with `RTM_NEWMDB`
+  (`drivers/net/vxlan/vxlan_mdb.c:292`).
+- The bridge dumps an entry's filter mode and source list only under
+  IGMPv3 or MLDv2; `br0` runs the defaults (IGMPv2, MLDv1). Its dump
+  also holds the kernel's own MLD host joins (`ff02::6a` and the
+  solicited-node groups).
+- The VXLAN leaves out a port of 0 or its own 4789, a VNI that is its
+  own (100), and the source VNI unless it is `external`.
+- The dump's attribute numbers (`MDBA_MDB_EATTR_*`) differ from the
+  request's (`MDBE_ATTR_*`).
+
+**Oracles:**
+
+- **`pkg/xtcpnl/xtcpnl_mdb.go`:** `ParseMdbEntry`, `ParseMdbRequest` and
+  `ParseMdbDump`, which decode both attribute numberings.
+- **O3** (`pkg/xtcpnl/xtcpnl_ws_mdb_test.go`):
+  - the request is rebuilt from the row's axes alone: the type, the
+    flags, the entry with the looked-up indexes, and the nest in
+    `mdb_modify`'s order;
+  - the decoded request must equal it.
+
+  O3 checked 166 requests. An `ack-then-fail` row must send none.
+- **O4:**
+  - After an accepted add, the device's dump has the entry: in each of
+    VLANs 1 and 10 when none was given, with the state, protocol and, on
+    `vx0`, the dst, mode, source list, port, VNI and via.
+  - After a del, it is gone. Extra entries are ignored.
+
+  O4 checked 28 round trips.
+- **O5 doesn't apply**, as in W5a.
+- **Coverage:** `nlcapgen coverage` gains an `mdb` family
+  (`mdba_policy`, 2/2) and an `mdbe` family for the nest
+  (`vxlan_mdbe_attrs_pol`, 9/9). A family can now judge a nested
+  attribute's payload, and one request can count towards two families.
+- **Universe:** `RTM_GETMDB` is captured, so its exclusion in
+  `xtcpnl_universe_test.go` is gone (four exclusions remain).
+- **Determinism:** a second run of all 177 rows, on the same workbench
+  boot, matched on every row.
+
+**Tests:**
+
+- The parsers: `TestParseMdbEntry`, `TestParseMdbRequest` and
+  `TestParseMdbDump`.
+- The generator: `TestMdbBrJudge`, `TestMdbVxJudge`, `TestBuildMdb`,
+  `TestMdbBrAllVlans`, `TestDeriveBridgeDupGone`, `TestMatrixMdbRows`, and
+  five new `TestCovTally` rows.
+- The oracles: `TestMdbWantFromAxes`, `TestMdbRequestProblem`,
+  `TestMdbRoundTripProblem` and `TestWsMdbDump`.
+
+**Mutation:** 40 of 40 mutants killed, each by a relevant test. Three
+survived the first pass, and one didn't compile (it was rewritten and
+rerun):
+
+- **No test pinned the VXLAN's gone-row errno** (ENOENT, where the
+  bridge's is EINVAL). `TestMatrixMdbRows` now checks both.
+- **No hand-built row broke two O4 checks on the VXLAN:** its source list,
+  and an (S, G) entry dumping as INCLUDE. `TestMdbRoundTripProblem` has a
+  row for each.
+
+**Size:** the rows add 561 KB to `ws/`, 18 MB of 64 MB in all.
+
+##### W5c: `ss`
+
+`ss` is iproute2's one sock_diag client. It reads each inet table with
+`SOCK_DIAG_BY_FAMILY` on `NETLINK_SOCK_DIAG`. Its filter (`sport ge :1024`,
+`src 127.0.0.0/8`, `autobound` and so on) is compiled to bytecode that the
+kernel audits and runs per socket. No earlier row captured this protocol.
+The workbench now captures it: `xtcp2-nlcap` takes `--proto sock_diag`,
+whose stop sentinel is `ip link show dev lo` (filtered to protocol 0),
+because the default `ss -x` sentinel is itself sock_diag.
+
+`nlcapgen matrix -family ss -seed 1 -random 40` writes
+`nix/microvms/workbench/ss.rows.jsonl` from one space in
+`tools/nlcapgen/matrix_ss.go`:
+
+| axis | values (boundary values in bold) |
+|---|---|
+| proto | `-t`, `-u`, `-w`, `-M` (MPTCP), `-S` (SCTP) |
+| family | both, `-4`, `-6` |
+| ext | none, `-m`, `-i`, `--tos`, `-mi` |
+| state | default, `-a`, `-l`, `state established`, `exclude time-wait`, `state connected`, two `state` words, **`-B`** |
+| filter | none; each port operator in word and symbol form, with **`:0`**, **`:65535`**, `:65536` and `:-1`; IPv4 and IPv6 hosts and prefixes, **`/0`**, with and without a port; or, and, not, implicit and, parentheses; `autobound`; `fwmark` with and without a mask; `cgroup`; `dev lo`; `src localhost` |
+
+383 rows: 59 positive, 38 boundary, 268 corner and 18 negative. Every row's
+namespace holds the same sockets, opened by a pre step (`ssHolder`):
+- TCP listeners on 127.0.0.1:22, [::1]:80, 127.0.0.1:8080, [::]:443
+  (dual-stack) and 127.0.0.1:9000 (`SO_MARK` 0x10);
+- two established pairs, one of them v4-mapped through the dual-stack
+  listener;
+- UDP sockets on 127.0.0.1:53 and [::1]:5353, plus a connected one;
+- a raw ICMP socket.
+
+The namespace's port range is one port wide, so both autobound connects
+take 45000. A forked child holds the sockets for 10 s.
+
+**ss's side** (`misc/ss.c`):
+
+- `inet_show_netlink` sends one dump per family, AF_INET then AF_INET6
+  (only one with `-4` or `-6`).
+- `sockdiag_send` writes `idiag_states` in host order.
+  - The collector's own requests store a byte-swapped constant
+    (`pkg/xtcp/init.go`) that they write big-endian. That is why
+    `DeserializeInetDiagReqV2` reads the field big-endian;
+    `ParseInetDiagRequest` reads it the kernel's way.
+  - With no state option, the mask is the tables' defaults ORed
+    together: SS_CONN for tcp, mptcp and sctp, but only SS_ESTABLISHED
+    for udp and raw (`ss.c:276`, `280`). `-4` and `-6` OR in SS_CONN too
+    (`filter_af_set`).
+- `-m`, `-i` and `--tos` set ext bits 0x41, 0x0e and 0x30.
+- MPTCP's protocol, 262, is stored truncated in the u8 (6) and sent
+  again in `INET_DIAG_REQ_PROTOCOL`.
+- `-4` and `-6` also set the family addresses are parsed in, so an
+  address of the other family is refused (rc 1).
+- `dev` compiles to nothing (`ss.c:2059`). Any `and` or `or` holding it
+  sends no bytecode, and ss filters the replies itself.
+- A `cgroup` term makes ss probe kernel support first
+  (`ssfilter_check.c`): AF_INET, TCP, no states, `CGROUP_COND` 0.
+
+**iproute2 bugs** (recorded here only; the rows assert they are still
+there through a `bug` fact):
+
+- **`src localhost` tests only the first address.**
+  `ssfilter_bytecompile` builds every address of a name from the first
+  one (`a->addr`, not `b->addr`, `ss.c:1945`). The request carries two
+  `S_COND`s for 127.0.0.1, and `[::1]:80` is never listed. With `-4` or
+  `-6` the name resolves to one address, and the rows expect no bug.
+- **`sport ge :65536` passes every socket.** A port comparison's operand
+  is the u16 `no` field (`ss.c:1987`), so 65536 wraps to 0.
+  `sport = :65536` is a hostcond with an int port, which correctly
+  matches nothing.
+- **`sport = :-1` passes every socket.** `get_long` takes -1, which a
+  hostcond reads as any port.
+- **Bytecode padding leaks heap.** The bytecode buffer is `malloc`ed and
+  never cleared, so a hostcond's 2 padding bytes carry heap contents into
+  the request (seen as `87 e2`). The oracles never compare them.
+- **The cgroup probe runs for every `cgroup` term.**
+  `ssfilter_is_supported` caches the result in a copy of the table entry,
+  so `cgroup A or cgroup A` sends two probes (the `cgroup2` rows).
+- **`cgroup /` doesn't name the cgroup2 root.** `get_cgroup2_id` tries
+  the path as given first (`lib/fs.c:145`). In the guest `/` has no file
+  handle, so ss refuses it; on a host whose root has one, it would take
+  that id. The rows use `cgroup /sys/fs/cgroup`. `ip netns exec` mounts a
+  fresh sysfs without cgroup2, so a cgroup row mounts it first, in the
+  exec's private mount namespace.
+- **A prefix outside the brackets is refused.** `[2001:db8::]/32` reads
+  `/32` as the port (rc 1, the `v6slash` row); the prefix goes inside,
+  `[2001:db8::/32]`.
+
+**The kernel** (`net/ipv4/inet_diag.c` unless noted):
+
+- `inet_diag_bc_audit` (`:728`) checks:
+  - each op's yes and no: at least its length, at most 4 past the end,
+    a multiple of 4;
+  - every jump target is an op boundary (`valid_cc`);
+  - a hostcond's family and prefix length;
+  - `MARK_COND` needs CAP_NET_ADMIN (EPERM).
+
+  Every bytecode ss sent passes it.
+- `inet_diag_bc_run` (`:465`) matches an AF_INET condition against a
+  v4-mapped AF_INET6 socket, so `src 127.0.0.1` lists the mapped
+  `[::ffff:127.0.0.1]:443`.
+- An accepted socket keeps its listener's userlocks minus
+  `SOCK_BINDPORT_LOCK` (`net/core/sock.c:2570`), so `autobound` lists
+  both ends of an established pair.
+- `raw_diag`'s dump ignores `idiag_states`; ss drops the states it didn't
+  ask for itself (`ss.c:4330`).
+- `INET_DIAG_MARK` is sent only to a CAP_NET_ADMIN reader (`:128`).
+
+**Oracles:**
+
+- **`pkg/xtcpnl/xtcpnl_inet_diag_bc.go`:**
+  - `ParseInetDiagRequest` decodes the request;
+  - `InetDiagBcAudit` and `InetDiagBcRun` port the kernel's audit and
+    run.
+- **O3a** (`pkg/xtcpnl/xtcpnl_ws_ss_test.go`): each request matches the
+  row's facts. It checks the family order, the protocol (and its u8),
+  the protocol attribute, the states, the ext bits, and whether there is
+  bytecode. Any bytecode must pass the audit. Cgroup probes come first
+  and must match the probe's shape.
+- **O3b:** the bytecode is run over 143 probe sockets:
+  - the holder's sockets;
+  - a grid of ports, addresses, v4-mapped addresses, locks, marks,
+    devices and cgroups.
+
+  Each verdict must equal the filter the user meant: the row's `pred`
+  fact, a prefix notation the test evaluates on its own. On a `bug` row
+  they must disagree somewhere.
+
+  O3a and O3b checked 639 requests.
+- **O4:** each reply lists a holder socket in a requested state that
+  passes the filter, with its mark. Every holder socket that passes
+  is listed. The filter is the pred, or on a bug row the bytecode as
+  sent; on a row with no bytecode it is no filter. O4 checked 607 round
+  trips. The 32 cgroup requests are skipped, because the holder's cgroup
+  id is unknown to the model.
+- **O5 doesn't apply:** goip has no sock_diag.
+- **Coverage:** inet_diag requests have no nla policy, so `nlcapgen
+  coverage` counts their bytecode ops on a line of their own: 10 of 14
+  (667 requests). ss never sends `NOP`, `DEV_COND`, `S_EQ` or `D_EQ`:
+  `dev` compiles to nothing, and `sport = :N` is a hostcond, not an
+  `S_EQ`.
+- **Determinism:** a second run of all 383 rows, on the same workbench
+  boot, matched on every row.
+
+**Tests:**
+
+- The parser: `TestParseInetDiagRequest`, `TestInetDiagBcAudit`,
+  `TestInetDiagBcRun` and `TestBitstringMatch`.
+- The generator: `TestBuildSs`, `TestSsFamilyExcl`,
+  `TestRowValidateProto`, `TestMatrixSsRows`, `TestCovAddDiag`,
+  `TestTallyCorpusSockDiag`, and two new `TestWriteCoverage` rows.
+- The oracles: `TestSsParsePred`, `TestSsPredPasses`,
+  `TestSsWantFromAxes`, `TestSsRequestProblem`,
+  `TestSsCgroupProbeProblem`, `TestSsRoundTripProblem`,
+  `TestSsExchangeProblems` and `TestWsSsExchanges`.
+
+**Mutation:** 47 of 47 mutants killed, each by a relevant test. Six
+survived the first pass:
+
+- **A PROTOCOL attribute longer than 4 bytes wasn't tested.**
+  `TestParseInetDiagRequest` now has an 8-byte row.
+- **Four oracle paths were exercised only by the corpus:** the family
+  order, an O3b disagreement, a bug that is gone, and the cgroup probe's
+  shape. A clean corpus never trips them. They moved into
+  `ssExchangeProblems`, and `TestSsExchangeProblems` holds hand-built
+  rows that break each one.
+- **Nothing read a real sock_diag capture through the coverage tally.**
+  `TestTallyCorpusSockDiag` does.
+
+**Size:** the rows add 1.5 MB to `ws/`, 18 MB of 64 MB in all.
+
+##### W5d: `ethtool`
+
+`ethtool` 7.1 talks to the kernel's `ethtool` generic netlink family. It is
+the first workbench client on `NETLINK_GENERIC`. Every row loads
+`netdevsim` and makes a fresh device, `eth0`, in its own namespace (the
+pre step `ethSetup`; the device id is 900 plus the namespace's number, so
+parallel rows never share one). Rows capture with `--proto generic`.
+
+`nlcapgen matrix -family ethtool -seed 1 -random 20` writes
+`nix/microvms/workbench/ethtool.rows.jsonl` from six spaces in
+`tools/nlcapgen/matrix_ethtool.go`:
+
+| space | command | axes (boundary values in bold) |
+|---|---|---|
+| `ethring` | `-G` (RINGS_SET 16) | each absent or: rx 1, 1024, **4096** (netdevsim's max); tx 1, 256, **4096**; rx-mini **0**, **4096**; rx-jumbo 100; tcp-data-split on, off, auto; hds-thresh **0**, **1024** |
+| `ethchan` | `-L` (CHANNELS_SET 18) | combined 1, 2, **4** (the device's queues); rx, tx, other **0** |
+| `ethpause` | `-A` (PAUSE_SET 22) | autoneg off; rx, tx on/off |
+| `ethfec` | `--set-fec` (FEC_SET 30) | off, auto, rs, baser, llrs, and the corners two modes, auto plus a mode, off plus a mode, mixed case |
+| `ethcoal` | `-C` (COALESCE_SET 20) | adaptive-rx/tx, the usecs and frames (plain, irq, low, high), pkt-rate-low/high, sample-interval, cqe-mode-rx/tx, tx-aggr-*, rx-cqe-* |
+| `ethshow` | `-g -l -a -c --show-fec -T -k` (their GETs) | none, `--json`, `-I`; `eth0` or `lo` |
+
+244 rows: 73 positive, 37 boundary, 81 corner and 53 negative. The
+negatives are out-of-range values (`4097`, 2^32, 2^32+1, `-1`), a
+repeated argument, a missing value, parameters netdevsim doesn't support,
+`nosuch0` (ENODEV) and `lo` (EOPNOTSUPP). Each row that sets something
+reads it back with the matching show command. `ethShowJSON` adds a
+`--json` row of `eth0` for each JSON command the pairwise rows missed.
+
+**`ethtool`'s side** (`ethtool-7.1/`):
+
+- Every command looks the family up (`CTRL_CMD_GETFAMILY`). A show
+  command also dumps the GET operation's policy (`CTRL_CMD_GETPOLICY`,
+  `netlink/netlink.c:259`) to learn which header flags it takes. `-I`
+  sets `ETHTOOL_FLAG_STATS` only when that policy allows it
+  (`netlink.c:289`): PAUSE_GET, FEC_GET and TSINFO_GET. On `-g`, `-l` and
+  `-c` the flag is silently dropped. These are the corpus's first
+  `CTRL_CMD_GETPOLICY` captures, so `TestNetlinkUniverse` no longer
+  excludes it.
+- `--set-fec encoding off` sends the link mode name `None`
+  (`netlink/fec.c:356`). Any other word is upper-cased, so `none`
+  becomes `NONE`, which names no link mode. The kernel answers
+  EOPNOTSUPP, "bit name not found" (`net/ethtool/bitset.c:415`).
+- `--json` with `-T` is refused before any request (`ethtool.c:6743`).
+
+**`ethtool` bugs** (recorded here only):
+
+- **A bare `hds-thresh` reads past argv.** Its parser entry has
+  `min_argc = 0` (`netlink/rings.c:205`); every other ring parameter
+  has 1. `ethtool -G eth0 hds-thresh` hands the u32 parser a NULL and
+  prints `invalid value '(null)' for parameter 'hds-thresh'`. It still
+  exits 1 before sending anything (the `ethring/ng-017` row).
+- **Four coalescing JSON keys differ from their parameters.** The
+  printer names `rx-frames-low` `rx-frame-low` (`netlink/coalesce.c:72`),
+  and likewise `tx-frame-low`, `rx-frame-high` and `tx-frame-high`
+  (`:76`, `:81`, `:85`). So `ethtool --json -c` output can't be fed back
+  as `-C` arguments by name. The JSON oracle's key table follows the
+  printer.
+
+**The kernel and netdevsim:**
+
+- `tcp-data-split auto` is stored as UNKNOWN, which netdevsim reports as
+  ENABLED (`drivers/net/netdevsim/ethtool.c:77-78`). The row reads back
+  on (`rt.tcp-data-split=2`).
+- A channel count of 0 for a type whose max is 0 is left out of the
+  reply (`net/ethtool/channels.c:64-83`). The rows expect it absent.
+- netdevsim's `set_coalesce` copies only `struct ethtool_coalesce`
+  (`netdevsim/ethtool.c:56-63`). Every `kernel_ethtool_coalesce` field
+  (cqe-mode-rx/tx, tx-aggr-*, rx-cqe-*) is accepted and reads back 0.
+  Those rows carry `rt.<arg>=0`.
+- `autoneg on` for pause is EINVAL (`netdevsim/ethtool.c:37`), so
+  ethtool exits 76.
+- `lo` has no ring, channel, pause, coalescing or FEC operation, so
+  each of those GETs is EOPNOTSUPP. `-T` and `-k` work on it.
+
+**Oracles:**
+
+- **The parser** (`pkg/xtcpnl/xtcpnl_ethtool.go`): `ParseEthtool` now
+  decodes coalescing (`EthtoolCoalesce`, every u32 and u8 attribute;
+  the two profile nests stay raw).
+- **O3** (`pkg/xtcpnl/xtcpnl_ws_ethtool_test.go`): the one SET request
+  carries the row's device in its header and exactly the attributes its
+  facts name, each with its value. For FEC, the mode names (as a
+  no-mask bitset) and auto. A show row's GET has the command, the
+  device, and the STATS flag exactly when `-I` asks and the policy
+  allows. A refusal before sending (`ack-then-fail`) sends no SET.
+- **O4:** the readback's GET reply holds each attribute set, as set or
+  as its `rt.` fact, and leaves out the `absent` ones. For FEC, the
+  configured link-mode bits, auto and the active mode.
+- **JSON:** each `--json` key of rings, channels, pause and coalescing
+  names a reply attribute, and its value equals the reply's.
+- O3 checked 231 requests, O4 170 round trips and 47 JSON values.
+- **O5 doesn't apply:** goip has no ethtool.
+- **Coverage:** `nlcapgen coverage` now reads generic netlink. It names
+  the family ids from each capture's `CTRL_CMD_NEWFAMILY` replies and
+  holds each SET to its kernel policy (`ethnl_*_set_policy`). Rings
+  12/12, channels 5/5, coalescing 30/32, pause 4/5, FEC 3/3. Never sent:
+  `RX_PROFILE` and `TX_PROFILE` (ethtool 7.1 has no parameter for them)
+  and pause `STATS_SRC` (`NLA_REJECT` in a SET). The YNL-generated
+  header's `X_MAX = (__X_CNT - 1)` entries now evaluate.
+- **Determinism:** a second run of all 244 rows, on the same workbench
+  boot, matched on every row.
+
+**Tests:**
+
+- The parser: `TestEthtoolCoalesce`.
+- The generator: `TestEthBuild`, `TestEthShowJudge`, `TestEthShowJSON`,
+  `TestMatrixEthtoolRows`, `TestCovGenlIDs`, `TestCovAddGenl`,
+  `TestTallyCorpusGenl`, four new `TestUapiEnum` rows and two new
+  `TestCheckRows` rows (a readback's protocol).
+- The oracles: `TestEthWantFromAxes`, `TestEthRequestProblem`,
+  `TestEthRoundTripProblem`, `TestEthFecProblems`, `TestEthBitIndexes`,
+  `TestEthShowProblem`, `TestEthJSONProblem`, `TestEthJSONValue` and
+  `TestEthGenlID`.
+- The new captures moved two benchmarks' picks. `ParseGenericNetlinkFamily`
+  now picks only NEWFAMILY replies (the smallest nlctrl message became a
+  policy dump). `ParseEthtool` picks only the replies and notifications
+  it classifies (the largest became a reply it doesn't decode).
+
+**Mutation:** 45 of 45 mutants killed, each by a relevant test. One
+survived the first pass:
+
+- **`covGenlIDs` would have taken a family id from a request.** Nothing
+  sent a request carrying `CTRL_CMD_NEWFAMILY`'s command.
+  `TestCovGenlIDs` now has that row.
+
+Two mutants didn't compile the first time and were rewritten. While
+writing the driver, one more gap turned up before the run: nothing
+checked a readback's protocol, so `TestCheckRows` gained its two rows.
+
+**Size:** the rows add 1.1 MB to `ws/`, 20 MB of 64 MB in all.
+
+### Captures an outside consumer needs: BIRD's netlink parser
+
+Counted from the tree on 2026-10-31. The BIRD routing daemon's kernel protocol
+(`sysdep/linux/netlink.c` in [BIRD](https://gitlab.nic.cz/labs/bird)) is
+being unit-tested and fuzzed with messages taken from these captures, so that
+its parser sees real kernel output rather than hand-built bytes. Across every
+`.pcap` under `pkg/xtcpnl/testdata/`, de-duplicated by message bytes, there
+are 504 `RTM_NEWROUTE`, 46 `RTM_DELROUTE`, 86,585 `RTM_NEWADDR` and 10,210
+`RTM_NEWLINK` (40 link kinds), and 17 routes carry `RTA_MULTIPATH` (10
+`AF_INET`, 6 `AF_INET6`, 1 `RTNL_FAMILY_IPMR`). Seven kernel refusals of a
+route request, and 153 refusals carrying extack TLVs, cover BIRD's error-reply
+path. Three things BIRD parses are in **no** capture:
+
+| Missing | What BIRD parses | Capture needed | Guest needs |
+|---|---|---|---|
+| bridge FDB entries | `RTM_NEWNEIGH`/`RTM_DELNEIGH` with `ndm_family = AF_BRIDGE` (`nl_parse_fdb`); all 414 neighbour messages in the tree are `AF_INET`/`AF_INET6` | `bridge fdb show` on a bridge with static and learned entries, and `bridge fdb add`/`del` under `ip monitor all` | the `bridge` module, the same gap as the **3 bridge / VLAN** row above |
+| bridge VLANs | `RTM_NEWVLAN`/`RTM_DELVLAN` (`nl_parse_vlan`); none in the tree | `bridge vlan show` and `bridge vlan add`/`del` on a `vlan_filtering 1` bridge | as above |
+| MPLS routes | `rtm_family = AF_MPLS` routes, `RTA_NEWDST` label stacks, and `RTA_ENCAP` with `LWTUNNEL_ENCAP_MPLS` on IP routes, single path and inside `RTA_MULTIPATH`; the tree has no `AF_MPLS` route and no `RTA_ENCAP` at all | `ip -f mpls route show`, `ip -f mpls route add 100 as 200/300 via inet 192.0.2.10 dev X`, `ip route add 198.18.20.0/24 encap mpls 100/200 via 192.0.2.10 dev X`, and a multipath route with a per-nexthop `encap mpls` | `mpls_router` and `mpls_iptunnel` modules, `net.mpls.platform_labels` above the labels used, and `net.mpls.conf.<dev>.input=1` |
+
+Routes BIRD installed itself (`rtm_protocol = RTPROT_BIRD`, 12) need no new
+capture: the BIRD test rewrites that byte in a captured route.
+
+#### Plan: B1–B3, the captures, their parsers and the completeness test
+
+The work order is the usual one: captures, then parsers with table tests and
+benchmarks, then a test that every capture is there.
+
+**B1, captures.** `nix/microvms/scripts/brmpls-write-corpus.exp` holds 36 rows,
+run by the link-write capture (`nix run .#microvm-x86_64-link-write-capture`,
+or these rows alone with `nix run .#microvm-x86_64-link-write-capture-brmpls`)
+into `link-write/brmpls/<slug>/`. They run last, after
+`xtcp2-nlcap modules brmpls mpls_router mpls_iptunnel`: `mpls_router` gives
+every device an `AF_MPLS` netconf and stats entry, which no earlier row may
+see. Each row rebuilds its namespace:
+
+- **FDB** (8 rows): `br0` with `vlan_filtering 1`, the veth port `v0`, and
+  `v0`'s peer `v0p` outside the bridge with a fixed MAC. The learned entry
+  comes from `v0p`'s DAD neighbor solicitation, and a `wait-learned` pre
+  step polls `bridge fdb show dev v0` for it, under `timeout 20`. With a
+  `dev` filter, `bridge` leaves `dev v0` out of its lines, so the poll
+  matches the MAC alone. Rows: show (static, VLAN and learned
+  entries), add static, add in a VLAN, add existing, replace, del, del
+  missing, and an `ip monitor all` event row.
+- **VLAN** (10 rows): show (RTM_GETVLAN's dump, plus the old `RTM_GETLINK`
+  `RTEXT_FILTER_BRVLAN` dump, its compressed form, and `vlan global`), add,
+  add a range, add the PVID untagged, add on the bridge itself (`self`), add
+  the reserved VID 4095, del, del a range, `set ... state`, and an event
+  row. `ip monitor` never joins `RTNLGRP_BRVLAN`, so the event row runs
+  `bridge monitor vlan` under the new `xtcp2-nl-brmon` helper
+  (`nix/microvms/netlink-capture.nix`), whose canary is a VLAN it adds
+  until the monitor prints it.
+- **MPLS** (18 rows): `platform_labels 1000` and `d0` with
+  `net.mpls.conf.d0.input 1`. `AF_MPLS` swap (`100 as 200/300`), pop,
+  multipath, a `via inet6`; refusals for an existing label, the reserved
+  label 3 and label 2000 (past the table); show, get, del, del missing
+  (accepted), del past the table. Then `encap mpls` on IPv4 and IPv6 routes,
+  with `ttl`, inside `RTA_MULTIPATH`, a show of all three, and an
+  `ip monitor route` event row.

+
+#### Delivered: B1–B3 (2026-10-31)
+
+- **Captures.** `pkg/xtcpnl/testdata/7_3_0/link-write/brmpls/`, 36 rows, from
+  the brmpls section alone. The full link-write run took hours on a loaded
+  host and timed out twice before it reached these rows, last of all. So
+  the runner now takes `--only <sections>`
+  (`nix/microvms/scripts/link-write-sections.exp`: lacp, addr, write, rtnl,
+  genl, xfrm, kinds, brmpls), and each section has its own app,
+  `microvm-x86_64-link-write-capture-<section>`. A section run writes the
+  same bytes as a full run would: every row rebuilds its namespace, and
+  late setup runs whenever a section after it is picked.
+  `link-write-sections-test.exp` (34 rows, in `checks.vm-lib-exp`) pins the
+  names, their order, and the driver refusing a bad list before it boots
+  anything.
+- **The first section run found a dead poll.** `wait-learned` grepped for
+  `^<mac> dev v0 `, a form `bridge fdb show dev v0` never prints, and its
+  loop could outlast `pre_step`'s 30 s and still be running when the next
+  row's command was typed. The pattern is now `learned_re`, tested against
+  the line a real `bridge` printed, and the loop is under `timeout 20`.
+- **Parsers.** `ParseNeigh`'s `NDA_MASTER` and `NDA_VLAN`, `ParseBrVlan`,
+  and the MPLS label, `RTA_NEWDST` and `RTA_ENCAP` decoding, as planned, with
+  hand-built tables (`TestParseNeigh`, `TestParseBrVlan`,
+  `xtcpnl_mpls_test.go`) and three `parseBenchCases` rows run against the
+  brmpls corpus.
+- **Corpus tests** (`xtcpnl_brmpls_corpus_test.go`):
+  - `TestBrMplsCorpusComplete`: B3's rows, plus a corner row that the
+    corpus has no directory the table does not name.
+  - `TestBrMplsCorpusWrites`: each row's write, decoded with the parsers
+    under test, and the kernel's answer (26 rows).
+  - `TestBrMplsCorpusReplies`: the dumps, readbacks and event rows'
+    notifications, decoded in the kernel's order (17 rows).
+- **What the bytes showed, against the plan's table:**
+  - `bridge vlan add` and `del` still use the old API: an `RTM_SETLINK` or
+    `RTM_DELLINK` with `IFLA_AF_SPEC`. Only `bridge vlan set` sends
+    `RTM_NEWVLAN`, with `BRIDGE_VLAN_INFO_ONLY_OPTS` (64). So B2's
+    `RTM_NEWVLAN` rows are checked against each row's `getvlan` readback,
+    and the VLAN event row's notifications, not its write.
+  - `bridge vlan show dev v0` dumps every port and filters in userspace
+    (`bridge/vlan.c`, `filter_index`), so every readback holds br0's entry
+    too.
+  - Deleting a missing label in range is acked; label 3 is refused by
+    `nla_get_labels`'s implicit-null check, not by the reserved-range check.
+  - `RTM_GETVLAN` was one of `TestNetlinkUniverse`'s exclusions ("bridge
+    only"). The test flagged the exclusion as stale once the corpus held
+    it, and it is removed: five exclusions remain.
+
+#### Still missing for BIRD: B4, each namespace's links and addresses (2026-10-31)
+
+BIRD's tests now use the brmpls MPLS rows: `mpls_route_show`,
+`mpls_route_add_via6`'s readback, `route_encap_show` (both families) and
+`mpls_event`. Every captured route parses to what `ip` printed. The bridge
+rows can't be used yet. **No brmpls row records the links or the addresses
+of its namespace**, and BIRD needs both before it accepts anything else
+from that namespace:
+
+- **Links.** Every `RTM_NEWLINK` in a brmpls `ip.pcap` or readback is a reply
+  to the name lookup `ip`/`bridge` makes before printing. It is 40 bytes, and
+  `IFLA_IFNAME` is its only attribute. BIRD's `nl_parse_link` needs
+  `IFLA_MTU` and rejects these ("KIF: Malformed message received"), so the
+  interface stays unknown. Every route on it is then dropped ("unknown
+  ifindex"). The one exception is `fdb_event`, whose `ip monitor all` saw full
+  br0 and v0 messages, but in a namespace with the canary interface.
+- **Addresses.** BIRD keeps a route only if its gateway is on a connected
+  subnet of the interface (`neigh_find`). No brmpls row has an
+  `RTM_NEWADDR` dump. 192.0.2.1/24 on d0 is visible only in `topology`.
+- **The bridge itself.** `nl_parse_vlan` takes a VLAN only from a bridge it
+  knows has VLAN filtering on. It learns that from br0's full link message:
+  `IFLA_LINKINFO` kind `bridge`, `IFLA_INFO_DATA` → `IFLA_BR_VLAN_FILTERING`.
+  `nl_parse_fdb` likewise needs br0's index and v0 as a known port.
+
+Correction to the **bridge VLANs** row above: BIRD's `nl_parse_vlan` reads
+the old form, `RTM_NEWLINK` with `ifi_family = AF_BRIDGE` and
+`IFLA_AF_SPEC` → `IFLA_BRIDGE_VLAN_INFO`, not `RTM_NEWVLAN`. Its own writes
+are `RTM_SETLINK`/`RTM_DELLINK`, the same as `bridge vlan add`/`del`. So
+`vlan_show`'s `netlink_route_getlink_brvlan.pcap` is the right reply. Its two
+`AF_BRIDGE` messages, for br0 and v0, are full. What it lacks is the
+`AF_UNSPEC` links next to them, which are name lookups again.
+
+**Workaround in BIRD until then.** The MPLS tests take goip0's full link and
+address messages from `7_3_0/dumps/` and rename them to d0 with the index
+changed: 3, or 4 in `mpls_event`, where the canary `c0` takes 3. This works
+only because the brmpls `topology` gives d0 goip0's addresses. There is no
+captured bridge link to start from, so the FDB and VLAN tests wait for B4.
+
+**B4, the fix.** Add two readbacks to the brmpls rows BIRD reads, taken
+after the row's command, with the same `{slug floor {command}}` shape as
+`ROUTE_RB`:
+
+```
+variable LINK_RB {{getlink 2 {ip -d link show}}}
+variable ADDR_RB {{getaddr 2 {ip addr show}}}
+```
+
+- `ip -d link show` and `ip addr show` with no `dev` filter, so the reply is
+  a full `NLM_F_DUMP` (every attribute, `IFLA_LINKINFO` included) rather
+  than a name lookup.
+- Rows: `fdb_show`, `fdb_event`, `vlan_show`, `vlan_event`,
+  `mpls_route_show`, `mpls_route_add_via6`, `route_encap_show` and
+  `mpls_event`, each appending `$LINK_RB $ADDR_RB` to its readbacks. For
+  the event rows, read back after the trigger: their links stay up, and
+  BIRD loads the links before replaying the events.
+- Optional: drop the canary from `mpls_event`, or keep it and record in the
+  row that d0 is index 4. Either way, the readback makes the index explicit.
+
+B4's tests extend `TestBrMplsCorpusComplete`:
+
+| description | input | expected |
+|---|---|---|
+| positive: every BIRD row has a link and an address readback | the 8 slugs above | `netlink_route_getlink.pcap` and `netlink_route_getaddr.pcap` in each |
+| positive: a link readback is a full dump | each `getlink` pcap | every `RTM_NEWLINK` has `IFLA_MTU` and `IFLA_LINKINFO` (lo has no `IFLA_LINKINFO`, so skip it) |
+| negative: a name-lookup reply is not a link readback | a 40-byte `RTM_NEWLINK` holding only `IFLA_IFNAME` (today's `ip.pcap`) | the test names the row |
+| positive: br0's link says VLAN filtering is on | `vlan_show`'s `getlink` | kind `bridge`, `IFLA_BR_VLAN_FILTERING` = 1 |
+| positive: d0 has the addresses of `topology` | each MPLS row's `getaddr` | 192.0.2.1/24 and 2001:db8::1/64 on d0 |
+| corner: the event rows' indexes | `mpls_event`'s `getlink` | c0 at 3, d0 at 4, as the routes' `RTA_OIF` say |
+| boundary: an address dump of a namespace without addresses | a row whose `topology` adds none | an empty dump (`NLMSG_DONE` only), not a missing file |
+
+Once these land, BIRD's FDB and VLAN tests use them directly. The MPLS tests
+then drop the renamed goip0 messages and load d0 from its own namespace.
+
+#### Delivered: B4 (2026-10-31)
+
+- **Captures.** `brmpls-write-corpus.exp` has `LINK_RB` and `ADDR_RB` as
+  above, appended (as `NS_RB`) to the eight rows' readbacks, after each
+  row's own. `nix run .#microvm-x86_64-link-write-capture-brmpls` rewrote the
+  whole `link-write/brmpls/` directory from one run. c0's and v0's MACs are
+  random on every run, br0 takes v0's, and the FDB rows' events carry them.
+  So a row's readbacks must come from the same run as its `ip.pcap`.
+  `brmpls-write-corpus-test.exp` pins which rows read back links and
+  addresses (those eight, and no others) and that neither dump has a `dev`
+  filter.
+- **Tests** (`xtcpnl_brmpls_corpus_test.go`): `TestBrMplsCorpusComplete`
+  expects both pcaps in the eight rows. `TestBrMplsCorpusLinkReadbacks`,
+  `…FullLinkProblem`, `…BridgeForBird`, `…AddrReadbacks` and
+  `…EventIndexes` hold the table's rows, with three changes the bytes forced.
+  `fullLinkProblem` is `nl_parse_link`'s test (`sysdep/linux/netlink.c:1088`
+  in BIRD): `IFLA_MTU` on every link, and `IFLA_LINKINFO` on every link but
+  lo. Three mutants of it are each caught by a row.
+- **What the bytes showed, against the table above:**
+  - Index 2 in every namespace is `nlmon0`, the capture device, so the
+    indexes are lo 1, nlmon0 2, then the row's devices. In `mpls_event`, c0
+    is 3 and d0 is 4, as the routes' `RTA_OIF` say; in the other MPLS rows
+    d0 is 3. The canary stays.
+  - lo is up in every row's namespace, with 127.0.0.1/8 and ::1/128. No
+    address dump is empty, so the boundary row is now "a namespace whose
+    devices have no address dumps only lo's" (`vlan_show`, `vlan_event`).
+  - `bridge`'s name lookups are not single lookups: `bridge` dumps every
+    link, names only (24-byte bodies), lo first. The negative row names lo.
+  - In the old-API VLAN dump BIRD reads, br0's own `AF_BRIDGE` entry
+    carries `IFLA_MASTER` = br0. `nl_parse_vlan` requires `IFLA_MASTER`, but
+    br0's entry has it, so BIRD takes br0's VLANs as well as v0's.
+  - BIRD dumps addresses per family (`AF_INET`, then `AF_INET6`); `ip addr
+    show` makes one `AF_UNSPEC` dump, which holds the same messages. Its
+    pcap also has the link dump `ip` makes first.
+

+# goip ↔ `ip` link kinds: implementation status
+
+**Last updated:** 2026-11-02
+
+**Summary:**
+- The design and the task plan are in [goip-link-kinds.md](goip-link-kinds.md). This document tracks progress against them.
+- The plan is written (DOC001).
+- KC0 is done (KC0-T01): the capture drivers load the kind modules late, after every existing row, with no fallback tunnel devices in the namespaces made afterwards, and a `kinds` sidecar records what the guest kernel creates. It creates 31 of the 32 probed kinds. gtp is refused, and KC4 decides why.
+- KC1 is done (KC1-T01): 18 `ip link set dev d0 inet …` rows, 11 the kernel answers and 7 `ip` refuses before netlink, are in the rtnl corpus. They are KP0's and KG0's source.
+- KC2 is done (KC2-T01, KC2-T02): a kind corpus (`kind-write-corpus.exp`) the link-write driver runs into `link-write/kinds/`, with 60 bridge rows and 42 bridge_slave rows, 80 the kernel accepts, 12 it refuses and 10 `ip` refuses before netlink. They are KP1's and KG1's source.
+- KC3 is done (KC3-T01, KC3-T02, KC3-T03): 28 vlan, 34 macvlan, 6 macvtap, 18 ipvlan and 4 ipvtap rows in the kind corpus, stacked on a dummy `d0`; of the 90, 54 the kernel accepts, 14 it refuses and 22 `ip` refuses before netlink. They are KP2's and KG2's source.
+- KC4 is done (KC4-T01, KC4-T02, KC4-T03, KC4-T04): KC4-T01 adds 73 vxlan rows, 46 the kernel accepts, 12 it refuses and 15 `ip` refuses before netlink; KC4-T02 adds 49 geneve rows, 22 accepted, 13 refused by the kernel and 14 by `ip`; KC4-T03 adds 16 bareudp and 20 amt rows, 11 accepted, 12 refused by the kernel and 13 by `ip`; KC4-T04 adds 19 gtp rows, 7 accepted, 4 refused by the kernel and 8 by `ip`. They are KP3's and KG3's source.
+- KC5 is done (KC5-T01, KC5-T02, KC5-T03, KC5-T04, KC5-T05; planned in DOC006): KC5-T01 adds 45 gre, 11 gretap and 25 erspan rows, 44 the kernel accepts, 16 it refuses and 21 `ip` refuses before netlink; KC5-T02 adds 36 ip6gre, 9 ip6gretap and 19 ip6erspan rows, 36 accepted, 14 refused by the kernel and 14 by `ip`; KC5-T03 adds 47 ipip and 37 sit rows, 46 accepted, 14 refused by the kernel and 24 by `ip` (`6rd-reset` has no row: it segfaults `ip`); KC5-T04 adds 49 ip6tnl rows, 29 accepted, 7 refused by the kernel and 13 by `ip`; KC5-T05 adds 23 vti, 12 vti6 and 23 xfrm rows, 27 accepted, 15 refused by the kernel and 16 by `ip`. They are KP4's and KG4's source.
+- KC6 is done (KC6-T01, KC6-T02, KC6-T03, KC6-T04; planned in DOC007): KC6-T01 adds 29 hsr rows, 10 accepted, 10 refused by the kernel and 9 by `ip`; KC6-T02 adds 43 netkit rows, 19 accepted, 8 refused by the kernel and 16 by `ip`; KC6-T03 adds 18 vrf, 10 vrf_slave and 18 vxcan rows, 18 accepted, 10 refused by the kernel and 18 by `ip`; KC6-T04 adds 17 batadv, 9 ifb, 6 nlmon, 13 vcan, 14 team and 4 team_slave rows, 29 accepted, 18 refused by the kernel and 16 by `ip`. They are KP5's and KG5's source.
+- KC7 is done (KC7-T01, KC7-T02; planned in DOC008): KC7-T01 commits the 7.3.0 link-write corpus, `testdata/7_3_0/link-write`, 10558 files from one run of the runner at the 7.2.0 pin, every kind row with its status, request and readbacks. KC7-T02 is the gate, `TestLinkKindUniverse`: of the 46 kinds 7.2.0's `iplink_*.c` and `link_*.c` name, 39 are captured with an accepted row and a `-d -j` readback, and 7 are excluded with a reason.
+- The KC tier is done.
+- KP0 is done (KP0-T01; planned in DOC009): `pkg/xtcpnl/xtcpnl_inet_devconf.go` encodes the `inet` write's `IFLA_AF_SPEC` byte for byte as `ip` does for the 11 KC1 rows the kernel answered, decodes it back, and decodes the dump's 33-value devconf array. KP1 is planned (DOC010).
+- KP1 is done (KP1-T01, KP1-T02; planned in DOC010): `pkg/xtcpnl/xtcpnl_bridge.go` is the bridge's 53-row option table and `xtcpnl_bridge_slave.go` the port's 44-row one. Each has a decoder that renders every accepted row's dump exactly as its `-d -j` readback prints it (50 bridge rows, 30 port rows), and an encoder that rebuilds the data nest of every row that sent a request byte for byte (55 and 37). `LinkInfo` carries `Bridge` and `BridgeSlave`. KP2 is planned (DOC011).
+- KP2 is done (KP2-T01, KP2-T02, KP2-T03; planned in DOC011): `pkg/xtcpnl/xtcpnl_vlan.go` decodes the vlan kind into `LinkInfo.Vlan`, rendering all 15 accepted rows' dumps as their `-d -j` readbacks print them, and encodes the `IFLA_INFO_DATA` of the 21 rows that sent a request byte for byte. `xtcpnl_macvlan.go` does the same for macvlan and macvtap into `LinkInfo.Macvlan` (25 accepted rows, 30 requests), and `xtcpnl_ipvlan.go` for ipvlan and ipvtap into `LinkInfo.Ipvlan` (14 and 17). KP3 is planned (DOC012).
+- KP3 is done (KP3-T01, KP3-T02, KP3-T03, KP3-T04; planned in DOC012): `pkg/xtcpnl/xtcpnl_vxlan.go` decodes the vxlan kind into `LinkInfo.Vxlan`, rendering all 46 accepted rows' dumps as their `-d -j` readbacks print them, and encodes the `IFLA_INFO_DATA` of the 58 rows that sent a request byte for byte, adds and sets alike. `xtcpnl_geneve.go` does the same for geneve into `LinkInfo.Geneve` (22 accepted rows, 35 requests), `xtcpnl_bareudp.go` for bareudp into `LinkInfo.Bareudp` (6 and 10), `xtcpnl_amt.go` for amt into `LinkInfo.Amt` (5 and 13) and `xtcpnl_gtp.go` for gtp into `LinkInfo.Gtp` (7 and 11); they share `xtcpnl_kind_wire.go`. KP4 is planned (DOC013).
+- KP4 is done (KP4-T01, KP4-T02, KP4-T03, KP4-T04, KP4-T05; planned in DOC013): `pkg/xtcpnl/xtcpnl_gre.go` decodes the six gre kinds into `LinkInfo.Gre`, rendering all 44 accepted gre, gretap and erspan rows' dumps as their `-d -j` readbacks print them, and encodes the `IFLA_INFO_DATA` of the 60 rows that sent a request byte for byte, sets seeded from their prefetch. `xtcpnl_gre6.go` does the same for ip6gre, ip6gretap and ip6erspan (36 accepted rows, 50 requests), and `xtcpnl_iptun.go` for ipip and sit into `LinkInfo.Iptun` (46 and 60), which ip6tnl's dump also fills; `xtcpnl_ip6tnl.go` encodes ip6tnl (29 accepted rows, 36 requests). `xtcpnl_vti.go` does the same for vti and vti6 into `LinkInfo.Vti` (18 and 25), and `xtcpnl_xfrm_link.go` for xfrm into `LinkInfo.Xfrm` (9 and 17). The shared `TunnelEncap` block lives in `xtcpnl_kind_wire.go`. KP5 is planned (DOC014).
+- KP5 is done (KP5-T01, KP5-T02, KP5-T03, KP5-T04; planned in DOC014): `pkg/xtcpnl/xtcpnl_hsr.go` decodes hsr into `LinkInfo.Hsr`, rendering all 10 accepted rows' dumps as their `-d -j` readbacks print them, and encodes the `IFLA_INFO_DATA` of the 20 rows that sent a request byte for byte. `xtcpnl_netkit.go` does the same for netkit into `LinkInfo.Netkit` (19 accepted rows, 27 requests), its `PEER_INFO` nest shared with `EncodeVethPeer` through `putPeerNest`. `xtcpnl_vrf.go` encodes vrf's 12 requests (the 8 accepted rows' dumps and the 3 enslaved vrf_slave rows' render through the existing `vrfTableAttr`), and `xtcpnl_vxcan.go` vxcan's 9 through `putPeerNest`; no vrf_slave request carries `INFO_SLAVE_DATA`. `xtcpnl_batadv.go` encodes batadv's 12 requests; batadv has no `fill_info`, and ifb, nlmon, vcan, team and team_slave send and dump no kind data at all, which `TestKindsWithoutData` holds for all 46 of their requests.
+- The KP tier is done. KG0 is planned (DOC015): KG0-T01 puts `inet` in goip's keyword chain, with `ip`'s exit statuses, and KG0-T02 gates its 11 matrix rows.
+- KG0 is done (KG0-T01, KG0-T02; planned in DOC015): goip builds `ip link set … inet …` byte for byte as `ip` does for the 11 KC1 rows the kernel answered, and refuses the 7 `ip` refuses with `ip`'s texts and statuses. `parseLinkArgs`' `exit(-1)` refusals now exit 255 through `ErrLinkUsage`. The 11 `link_inet_*` matrix rows are gated, on a clean full run and a clean `--section link` run (V135, V136), the first rows gated with a section run. KG1 is planned (DOC016).
+- KG1 is done (KG1-T01, KG1-T02, KG1-T03, KG1-T04, KG1-T05; planned in DOC016): goip builds `ip link add|set … type bridge …` byte for byte as `ip` does for KC2's 55 bridge rows that sent a request, and `ip link set … type bridge_slave …` for its 37 bridge_slave rows, lookups included, and refuses the 10 `ip` refuses with `ip`'s texts and statuses. `-d link show` renders a bridge as `ip` does for all 50 accepted rows, text and JSON, and a bridge port for all 30 of its accepted rows, with `ip`'s gets. The 92 write rows and 4 `-d` read rows are in the matrix and gated, on two clean `--section link` runs (V154, V155). KG2 is planned (DOC017).
+- KG2 is done (KG2-T01, KG2-T02, KG2-T03, KG2-T04, KG2-T05; planned in DOC017): goip takes `iplink_parse`'s `link` keyword, resolving the lower device before `IFLA_IFNAME` on a create, and builds `ip link add|set … type vlan|macvlan|macvtap …` byte for byte as `ip` does for KC3's 21 vlan, 25 macvlan and 5 macvtap rows that sent a request, lookups included, and refuses the 17 `ip` refuses with `ip`'s texts and statuses. KG2-T03 adds `type ipvlan|ipvtap …`: KC3's 14 ipvlan and 3 ipvtap rows that sent a request, and the 5 refusals. KG2-T04 renders `-d link show` of the five kinds as `ip` does for all 54 accepted rows, text and JSON, with `ip`'s gets. The 68 write rows and 10 `-d` read rows are in the matrix and gated, on two clean `--section link` runs (V169, V170). KG3 is planned (DOC018).
+- KG3 is done (KG3-T01, KG3-T02, KG3-T03, KG3-T04, KG3-T05; planned in DOC018): goip builds `ip link add|set … type vxlan …` byte for byte as `ip` does for KC4's 58 vxlan rows that sent a request, lookups included, prints `ip`'s dstport warning, refuses the 15 `ip` refuses with `ip`'s texts and statuses, and sends `ip -4`'s and `-6`'s default group. KG3-T02 adds `type geneve …`: KC4's 35 geneve rows that sent a request, and the 14 refusals. KG3-T03 adds `type bareudp|amt|gtp …`: KC4's 10, 13 and 11 rows that sent a request, and the 21 refusals. KG3-T04 renders `-d link show` and `-d -j link show` of the five kinds as `ip`'s print_opts do, for all 86 accepted KC4 rows with `ip`'s gets, and vxlan's `-d -d`. The 127 write rows and 11 `-d` read rows are in the matrix and gated, on two clean `--section link` runs (V186, V187). KG4 is planned (DOC019).
+- KG4 is done (KG4-T01 to KG4-T09; planned in DOC019). KG4-T01 has goip-parity set `fb_tunnels_only_for_init_net=2` before its first row, so a `--section link` run makes no fallback tunnels (V194). KG4-T02 adds the set prefetch every tunnel parser but xfrm's shares: `Service.LinkInfoDataByIndex`'s 32-byte `RTM_GETLINK` with no `IFLA_EXT_MASK`, sent without `NLM_F_CREATE` (so on `set`, `change` and `delete`) when a word follows the kind, with `ip`'s `Failed to get existing tunnel info.` checks. On it, goip builds `ip link add|set|delete … type gre|gretap|erspan …` byte for byte as `ip` does for KC5-T01's 31 gre, 10 gretap and 19 erspan rows that sent a request, lookups and prefetch included, and refuses the 21 `ip` refuses with `ip`'s texts and statuses (V195–V197). KG4-T03 adds `type ip6gre|ip6gretap|ip6erspan …` on the same prefetch: KC5-T02's 26, 9 and 15 rows that sent a request, and the 14 `ip` refuses (V198–V200). KG4-T04 adds `type ipip|sit …`: KC5-T03's 34 ipip and 26 sit rows that sent a request, and the 24 `ip` refuses; `6rd-reset`, which crashes `ip` 7.2.0, and a 6rd prefix of `any`, `all` or `default`, which `ip` parses but doesn't send, are `ErrNotImplemented` (V201–V203). KG4-T05 adds `type ip6tnl …`: KC5-T04's 36 rows that sent a request, and the 13 `ip` refuses; an encaplimit that is neither a u8 nor `none`, for which `ip` sends an uninitialized byte, is `ErrNotImplemented` (V204–V206). KG4-T06 adds `type vti|vti6|xfrm …`: KC5-T05's 16 vti, 9 vti6 and 17 xfrm rows that sent a request, and the 16 `ip` refuses; vti and vti6 share the prefetch, and xfrm has none (V207–V209). KG4-T07 renders the six gre kinds' `-d` output, matching every one of KC5-T01's and KC5-T02's 80 accepted rows' `-d` and `-d -j` readbacks; the decoder now keeps each endpoint's length, which `tnl_print_endpoint` reads as the family (V210–V212). KG4-T08 renders ipip's, sit's, ip6tnl's, vti's, vti6's and xfrm's, matching all 102 of KC5-T03's to KC5-T05's accepted rows; with it the 7_1_4 tunnel topology's `-d link show` and `-d addr show` render, matching their sidecars, and the refusal's test moves to hsr and netkit (V213–V215). KG4-T09 puts the 248 write rows and 24 `-d` read rows in the matrix, each write row's floor its capture's record count, the prefetch counted, and gates them on two clean `--section link` runs (V216–V221). KG5 is planned (DOC020).
+- KG5 is done (KG5-T01 to KG5-T07; planned in DOC020), and with it the plan. KG5-T01 sends ifb, nlmon, vcan, team, team_slave and vrf_slave through dummy's else arm (`Garbage instead of arguments`, 1; `help` not implemented), and adds `iplink_parse`'s `vrf NAME` (the resolver, then `Service.IsVRF`, `Not a valid VRF name` at 255, `IFLA_MASTER`) and `numtxqueues`/`numrxqueues` (`intAttr`, as `mtu`). goip builds all 42 of the six kinds' rows that sent a request byte for byte, lookups included, and refuses the 12 `ip` refuses with its texts and statuses; the workbench differential's `linkadd` rows go from 43 to 111 the same as `ip` (V223–V225). KG5-T02 adds `type hsr …`: KC6's 20 hsr rows that sent a request, byte for byte with the slaves' gets, and the 9 `ip` refuses; `version` and `proto` send any u8, as `ip`'s check does (V226–V228). KG5-T03 adds `type netkit …`: KC6's 27 netkit rows that sent a request, the peer's `PEER_INFO` parsed as veth's is, and the 15 `ip` refuses, `duparg`'s `(null)` included; `help` in the peer is `ErrNotImplemented` (V229–V231). KG5-T04 adds `type vrf|vxcan|batadv …`: KC6's 12, 9 and 12 rows that sent a request and the 19 `ip` refuses; vxcan is `vethData` with its own usage and `VXCAN_INFO_PEER`, and veth's peer `type` now exits 255 as `duparg` does, where it exited 1 (V232–V234). KG5-T05 moves the bond parsers' `invarg`s and incomplete line to 255, as `ip`'s are, keeps the rest at 1, and gives the address errors `ip`'s `Error: ` prefix; `link_bond_args.go` and `link_write.go` lose their six `//nolint:gosec` for bounded conversions (`s32Bits`, `u32AsS32`, `cIntBits`, `low32`), and an ifindex `ip` tests only for 0 goes out as its 32 bits (V235–V237). KG5-T06 renders hsr's and netkit's `-d` output, matching all 29 of KC6's accepted hsr and netkit rows' `-d` and `-d -j` readbacks, the slaves' gets included; every kind KC captured now renders, so the refusal's test moves to built links (V238–V240). KG5-T07 adds the eleven kinds' 122 write rows and 22 `-d` read rows to goip-parity's table, now 1246 rows, and gates all 144 after two clean `--section link` runs of 776 rows each (V241–V245).
+
+**Next action:** none in this plan; KC0 to KG5 are done. The full run before the next push is clean at 3a8bc8e3 (V246). The next goip parity work, the write keywords the workbench differential shows goip refusing, is planned in [goip-write-keywords.md](goip-write-keywords.md) and tracked in [its status doc](goip-write-keywords-status.md). The 474 G115 narrowing conversions are a separate TODO ([static-analysis.md](../static-analysis.md#todo-g115-the-narrowing-conversions-the-exclusion-hides)).

+## Update rules
+
+- States are `not started`, `in progress`, `blocked`, `done` or `deferred`. There are no percentages.
+- A task is `done` only when its "Done when" has passed and the evidence is in the [ledger](#verification-ledger).
+- Evidence IDs (`V###` for code and VM runs, `DOC###` for docs) are immutable and append-only.
+- Task IDs (`KCn-Tmm`, `KPn-Tmm`, `KGn-Tmm`) are never renumbered.
+- Every task's commit flips its own checklist row and appends its `V###` rows.
+- A phase's last task also closes the phase, following [Closing a phase](goip-link-kinds.md#closing-a-phase).
+- A statement elsewhere in `docs/netlink/` that a task makes false is amended in that task's commit.

+## Decision log
+
+**2026-10-24:**
+- **Kinds that need hardware or another creation path are out.** can, ipoib, dsa, rmnet, wwan and virt_wifi each need a lower device or hardware the VM doesn't have; netdevsim is created through sysfs, not rtnetlink. vcan, which is in, takes none of `iplink_can.c`'s options.
+- **XDP is class F.** `iplink_xdp.c`'s `-d` output makes a `bpf()` syscall per program, which nlmon can't see. `iplink_xstats.c` isn't a kind; `link xstats` is a G1 read already.
+- **maddress stays class F at the 7.2.0 pin.** `RTM_GETMULTICAST` reached `ip/ipmaddr.c` in `b8cdda55`, after the tag. [goip-parity-gaps.md](goip-parity-gaps.md#f-not-netlink-outside-pcap-parity) said "the 7.2 checkout" and is corrected. It is revisited at the next pin bump.
+- **No fallback tunnels after late setup.** `late_setup` sets `net.core.fb_tunnels_only_for_init_net=2` before it loads the tunnel modules, so the namespaces the link-write driver builds afterwards get no `tunl0`, `gre0`, `sit0`, `ip6tnl0` or the like, and no later fixture's ifindexes move. The dump driver's tunnel set keeps its fallback devices: it loads its modules before `late_setup`, and they are half its coverage.
+- **Kind modules load in `late_setup`,** not on demand through `rtnl-link-<kind>`, so the load happens at one known point after every existing row.
+- **The guest kernel is 7.3.0** (`linuxPackages_latest`). The 7.3.0 dump corpus (`testdata/7_3_0/dumps`) is the reference for the dump driver's comparisons; the link-write driver is compared with a run of the code before the task, since its committed blobs are older.
+- **gtp is refused by the guest kernel** (`late/kinds`: `RTNETLINK answers: Invalid argument`). `ip` 7.2.0 always asks for `IFLA_GTP_CREATE_SOCKETS`; KC4 finds the attribute the kernel wants, or moves gtp out of scope with the reason.
+- **`genl/mptcp_limits_set_over` fails on kernel 7.3, before this plan.** Kernel `c8646664fbf1` ("mptcp: pm: in-kernel: increase all limits to 64") raised the limit from 8 to 64, so `ip mptcp limits set subflows 9` is accepted. The link-write driver at `34724ad7`, before KC0, fails on the same row, so it is not KC0's. It is fixed outside this plan, in the corpus row, its hermetic check and the goip and goipparity rows that copy the limit; until then the link-write driver's `NLCAP_DRIVER_FAIL` on that one row is expected.
+- **An `ip` refusal before netlink exits with 1 or 255.** `invarg`, `incomplete_command` and `duparg2` call `exit(-1)`, so 255; a parse error returned up the stack instead (`parse_on_off`'s) reaches `do_cmd`, which exits with the negated return, so 1. KC1-T01's plan assumed 255 for both, and its first VM run corrected `inet_bad_on_off` to 1. Every corpus now admits both, and KG0 matches the status as well as the text.
+- **bridge's `ip` refusals exit 1 where `bridge_parse_opt` returns,** as the KC1 entry above has it: an abbreviated `strcmp` keyword (`stp_m`) is an unknown word, and `parse_one_of` returns on a name it doesn't know (`stp_mode bogus`). KC2-T01's plan said 255 for both; its first run (V012) corrected them.
+- **bridge's JSON keys aren't all its keywords.** `group_address` prints as `group_addr`, the `*_count` options as `*_cnt` and the `*_interval` ones as `*_intvl`; `group_fwd_mask` prints in hex. KG1's renderer follows the readbacks, not the keyword table.
+- **A port's `state` reads back what the bridge makes of it.** With STP off, `br_set_port_state` sets the state sent and then runs `br_port_state_selection`, which moves an enabled port to forwarding, so `set_state`'s `state 4` reads back `forwarding`. The request pins the 4; KG1 renders what the kernel reports, as `ip` does.
+- **An `ip` refusal can still send datagrams.** `backup_port` resolves its name with an `RTM_GETLINK` before `invarg` exits, so `set_backup_port_missing` has 4 datagrams at floor 0. A floor is a minimum, and the row's evidence is its `ip.err`.
+- **The VM namespace's rp_filter is 2,** not the kernel's 0, so `inet_rp_filter_max` writes the value it reads back. The row still pins the request; `inet_several` (`rp_filter 1`) shows a change.
+- **gtp is in scope; KC0's probe sent no option.** With nothing after `type gtp`, `iplink_parse` doesn't call `gtp_parse_opt`, no `INFO_DATA` goes out, and `gtp_validate` refuses `!data`. `role ggsn` is enough: `ip` then sends `IFLA_GTP_CREATE_SOCKETS`, and the kernel opens its own sockets. KC4-T04 has the rows; the KC0 entry above is answered.
+- **7.2.0's geneve option is `local`, not `local` and `local6`.** The plan named both; `iplink_geneve.c` has one `strcmp` keyword that sends `IFLA_GENEVE_LOCAL` or `IFLA_GENEVE_LOCAL6` by the address's family, and `local6`, like `remote6`, is only an output key. KC4-T02 has a row for each family and one for the word `local6`, which `ip` refuses.
+- **`get_addr` exits 1.** A bad or wrong-family address calls `exit(1)`, not `exit(-1)`, so an address `ip` can't parse reads like a returned error. KC4's tables use it; KC3's rows had no address.
+- **KC5's encap rows: fou is loaded, fou6 isn't.** `late_modules` already loads `fou` for its genl family, and it registers the IPv4 FOU and GUE encap ops, so gre's, ipip's and sit's encap rows are accepted. `fou6` isn't loaded, so the ip6 kinds' `encap fou`/`gue` rows are kernel refusals (`-EINVAL`). Their requests still carry every `ENCAP_*` attribute, which is what KP and KG need; loading `fou6` would add readbacks, not request coverage.
+- **The guest kernel has no `CONFIG_IPV6_SIT_6RD`.** sit's 6rd words are sent and ignored, so its 6rd rows are accepted and read back nothing; `sit/add_6rd_overlong` (48 + 24 bits, which a 6rd kernel refuses) is the canary if the config changes.
+- **KC5 is five tasks, one per iproute2 parser or pair.** The drafts were argued from `link_gre.c`, `link_gre6.c`, `link_iptnl.c`, `link_ip6tnl.c`, `link_vti.c`, `link_vti6.c` and `link_xfrm.c` at `v7.2.0` and the 7.3 kernel's checks. Two findings shape every task: a bare `type <kind>` is accepted, and every parser but xfrm's fetches the device before a set and resends its current values.
+- **sit's `6rd-reset` has no row: it segfaults `ip` 7.2.0.** `link_iptnl.c:288` passes the string literal `"2002::/16"` to `get_prefix`, whose `get_prefix_1` writes a NUL over the `/` (`lib/utils.c:693-695`), so `ip` faults on read-only memory before it sends anything. KC5-T03's first VM run found it (V046). KG5 decides whether goip refuses the word or sends what it was meant to, `2002::/16` with no relay prefix; parity can't compare a crash. Nothing is sent upstream.
+- **A set on sit's wildcard exits 255 before netlink.** The kernel gives a sit made with no `INFO_DATA` `ttl 64` and no DF (`ipip6_netlink_parms`), the set's prefetch seeds both, and `link_iptnl.c` refuses `ttl` nonzero with `nopmtudisc`. ipip's wildcard has `ttl` 0, so its sets reach the kernel. KC5-T03 keeps the two 255 rows and reaches the kernel's point-to-point check through a `ttl inherit` wildcard.
+- **KC6 is four tasks:** hsr; netkit; vrf, vrf_slave and vxcan; batadv with the five kinds `ip` has no parser for. The drafts were argued from `iplink_hsr.c`, `iplink_netkit.c`, `iplink_vrf.c`, `iplink_vxcan.c`, `iplink_batadv.c`, `iplink_ifb.c`, `iplink_nlmon.c`, `iplink_vcan.c` and `iplink_team.c` at `v7.2.0` and the 7.3 kernel's checks. Three findings shape every task:
+  - `iplink.c`'s `nodev` returns rather than exits, so a set on a missing device is 1. The tunnel parsers' `exit(nodev(…))` was 255.
+  - A set of only `type K` sends no `INFO_DATA` and reaches no kind code, so it is 0 for any kind.
+  - A kind with no `parse_opt` takes no word after `type`. Each word is Garbage (1), or `usage()` (255) for a prefix of `help`.
+- **hsr's `version` and `proto` checks in `ip` 7.2.0 test `get_u8`'s return, not the value** (`iplink_hsr.c:64-66`, `:71-73`). Any u8 passes, and the kernel refuses 2 and above. KC6-T01 pins it with `add_version_2` and `add_proto_2`; KG5 decides whether goip copies the check as written. Nothing is sent upstream.
+- **netkit's rows never run under `ip -batch`.** `netkit_parse_opt` keeps its state in statics, so a second row in one batch would inherit the first's.
+- **vxcan's usage goes to stdout.** `iplink_vxcan.c`'s `print_usage` ignores its `FILE *`, so `add_unknown`'s usage is in `ip.out`, not `ip.err`.
+- **batadv has one attribute, not two.** The inventory said 2; `IFLA_BATADV_ALGO_NAME` is the only member after `UNSPEC`.
+- **KC7 commits a 7.3.0 link-write corpus.** The kind captures lived only in the scratch runs the V### rows compared, and the committed link-write corpus is 7.1.4's, older than the kind corpus and the guest kernel. KC7-T01 commits one run's output at the runner's default, `testdata/7_3_0/link-write`, and leaves `7_1_4/` and the tests that name it alone. `genl/mptcp_limits_set_over` lands there with the kernel's 0 (V004).
+- **`corpusAll` skips the 7.3.0 link-write set.** The 17 corpus tests that tally every message under `testdata` count one capture of each row; the 7.3.0 set recaptures the 7.1.4 set's rows, so reading both doubles them. The kind tests read `tdLinkWrite_7_3_0` directly, and `TestCorpusAllSkipsLinkWrite730` pins the skip.
+- **7.2.0 names 46 link kinds, not 48.** The plan's count was wrong: `ip/iplink_*.c` and `ip/link_*.c` at `v7.2.0` hold 46 `link_util` ids. `macsec` (`ipmacsec.c`) and `tun` (`iptuntap.c`) are `link_util`s outside those files and outside the plan. With the 7 exclusions, 39 kinds are in scope.
+- **bond, bond_slave, dummy and veth are captured through shared readbacks.** Their `write/` rows predate `link-write-readback.exp` and have no readbacks of their own. The gate pairs each kind's accepted `write/` rows with a `-d -j` dump in the same corpus that shows a device of the kind: `lacp_converged/ip_link_n_json` for bond, bond_slave and veth, and `kinds/vrf_slave/set_master/ip_getlink_detail_json`'s `d0` for dummy.
+- **The `inet` request and dump don't share a shape.** The request's `IFLA_INET_CONF` carries `NLA_F_NESTED` and holds u32 attributes typed by devconf id; the dump's is a raw array of `IPV4_DEVCONF_MAX` u32s with no flag. KP0's codec keeps two decoders. The encoder refuses an empty list, since `ip` never sends one, and ids outside 1 to 33, but not `mc_forwarding` (2): the kernel's policy refuses that.
+- **The bridge's `vlan_protocol` is big-endian on the wire.** `ll_proto_a2n` returns the protocol byte-swapped and `addattr16` copies it, so KP1's parser reads it in network order.
+- **The bridge's keyword `ageing_time` is one constant.** misspell reads string literals and upper-case tokens, and the keyword must stay the kernel's spelling. `BridgeKeywordAgeingTime` assembles it from two halves and `IflaBrAgeingTime` is the enum's 4, so no lint exclusion is needed; goip reads both from `xtcpnl`.
+- **A kind's readback agreement uses the JSON readback's own pcap.** The text and JSON readbacks are two `ip` runs, and timers move between them (`gc_timer` 148.48 against 148.49). KP1-T02 and every later KP task compares a `-d -j` readback with the dump in `netlink_route_getlink_detail_json.pcap`.
+- **A new `LinkInfo` field regenerates `pkg/linkmonitor`'s replay goldens.** Their digest hashes the decoded links as JSON, so `Bridge` (and each later kind's field) changes it on every link. The value counts are the check that nothing else moved.
+- **Port attributes `ip` never prints still decode.** The kernel dumps the MRP and EHT counters and `mcast_n_groups`/`mcast_max_groups` on every port; `BridgeSlaveOptions` holds them as read-only rows with no keyword, so `Unknown` lists only ids past 45.
+- **Option keywords shared across tables are package constants.** goconst counts across `pkg/xtcpnl`, so a keyword two kinds' tables spell (bridge and bridge_slave's `priority`, `group_fwd_mask`, `mcast_router`; the port's and devconf's `proxy_arp`) is one constant rather than a lint exclusion. Later kinds reuse them.
+- **The plan's vlan flag mask was wrong.** `gvrp on mvrp on` is flags and mask 0xa, not 0x6: `VLAN_FLAG_MVRP` is 0x8 and `LOOSE_BINDING` 0x4, and `vlan_print_flags` prints MVRP first. `VlanFlags` keeps the print order.
+- **The plan's macvlan macaddr ops were wrong.** `enum macvlan_macaddr_mode` is add 0, del 1, flush 2, set 3; the plan had flush and set swapped. The codec uses the kernel's values.
+- **vxlan's `ageing` is one constant too.** As with the bridge's `ageing_time`, `VxlanKeywordAgeing` assembles the keyword and JSON key, `IflaVxlanAgeing` is the enum's value (8), and the Go field is `Aging`.
+- **The kernel never dumps `IFLA_VXLAN_MC_ROUTE`, and dumps `VNIFILTER` only when on.** `add_mcroute` is accepted, but its readback has no `mcroute`; only `add_vnifilter`'s has `vnifilter`. The parser decodes both when sent, and the readback test compares what the dump carries.
+- **vxlan's `tos` value is hex.** `rtnl_dsfield_a2n` reads it with `strtoul(…, 16)`, so `tos 10` is 0x10, as `add_tos`'s readback prints it.
+- **The vxlan encoder refuses what `vxlan_parse_opt` refuses.** `ErrKindSettingConflict` covers group and remote together, a local of the other family, vnifilter without external, external with an id, no id on an add, and a group without dev; `ErrKindSettingRange` covers a value out of range and a group, remote or local of the wrong cast. The default group `ip -4` and `-6` send when no address is given is not modeled; no row uses it.
+- **The plan's group/remote mutant moved to the encoder.** The parser keeps one `Group` address and makes no choice; the group-or-remote key is the render's (KG3), so the mutant inverted the encoder's multicast check instead.
+- **The plan's geneve order was wrong for two attributes.** `geneve_parse_opt` sends `TTL_INHERIT` and `DF` inside its loop, in argument order, ahead of `ID`; only the rest waits for the loop to end. `ttl inherit` also marks the ttl given, so a set with it sends `TTL` 0 after the loop. A corner row pins it.
+- **The kernel dumps geneve attributes `ip` never prints.** `geneve_fill_info` sends `PORT_RANGE` on every device and `GRO_HINT` when on; the parser decodes both, and the readback test compares only what `ip` prints.
+- **The kinds' wire helpers are shared.** The tolerant reads, range-checked writes, the 24-bit VNI and flow-label bounds, and `ErrKindSettingConflict` (vxlan's conflict error, renamed when geneve needed the same) live in `xtcpnl_kind_wire.go`.
+- **The plan's bareudp order was wrong.** `bareudp_parse_opt` sends nothing inside its loop: after it, `PORT` and `ETHERTYPE` always, `SRCPORT_MIN` when given and `MULTIPROTO_MODE` when on, whatever order the words came in. The plan said argument order; a corner row pins the real one.
+- **A missing word has its own error.** `ErrKindSettingMissing` is a required word not given (vxlan's and geneve's id, geneve's remote on an add, bareudp's dstport and ethertype); `ErrKindSettingConflict` keeps the words that clash. vxlan's and geneve's missing-id cases moved to it, so KG3 can map each to `ip`'s own text (`missarg` against a conflict message).
+- **amt's kernel checks stay the kernel's.** A link, a mode and a local on an add, and a discovery for a gateway, are `amt_validate`'s refusals, not `ip`'s, so `EncodeAmtInfoData` sends what it's given, as `add_no_link` and `add_gateway_no_discovery` do. It refuses what `amt_parse_opt` does: a second `local` or `discovery`, a mode with no name, and a port too wide.
+- **The plan's amt lower mutant moved to the parser.** Printing the lower as a number is the KG render's; the KP3-T03 mutant drops `LINK`'s ifindex instead.
+- **gtp prints `unknown` for a role past sgsn.** The plan said the render has no name; `gtp_role_to_string` returns `unknown`. The parser also skips `LOCAL` and `LOCAL6` with the request-only `FD0`, `FD1` and `CREATE_SOCKETS`; the kernel dumps none of them.
+- **"Where goip stands" lagged.** KP1's and KP2's closes didn't add their kinds to it; KP3's close adds all three phases' rows.
+- **The tunnel encoders take the device, not a bool.** A set's request is the prefetch's values plus the words, so `Encode<Kind>InfoData` takes the decoded `cur`, nil on an add, and the tests decode it from the reply in `ip.pcap`.
+- **The prefetch's two `ip` bugs are copied, not fixed.** gre, gre6, iptnl and ip6tnl re-send an unnamed encap port byte-swapped (`ip6gre/set_encap_sport_swap`); vti and vti6 seed `LINK` with `rta_getattr_u8`, keeping only the low byte of the ifindex. The encoders match `ip` byte for byte, and goip copies them too (DOC019; KG4-T02's swapped-port prefetch row holds gre's). Nothing is sent upstream.
+- **One gre encoder covers gre, gretap and erspan.** `link_gre.c` parses all three; `EncodeGreInfoData` takes an `erspan` bool for the erspan-only words and the `ERSPAN_VER` default, as `gre_parse_opt` keys them on the kind name.
+- **KP4-T01's encode table gains a row.** No corpus row gives an index at version 2, so the plan's third mutant survived its table; `corner: an index at version 2 is not sent` is built to kill it.
+- **A malformed endpoint is dropped, not marked.** `tnl_print_endpoint` prints `unknown` for a `LOCAL` or `REMOTE` that isn't 4 or 16 bytes; `ParseGreInfoData` keeps the zero address, which renders `any`, so KP4-T01's short-remote row expects `any`. The kernel always sends 4 or 16 bytes. A 16-byte address on gre, or a 4-byte one on an ip6 kind, still renders `unknown`.
+- **The ip6 gre kinds share gre's setting type.** `EncodeGre6InfoData` takes `GreSetting`, with `EncapLimit`, `TClass`, `FlowLabel` and `TnlFlag` added; each encoder refuses the other's options with `ErrKindSettingOption`. It takes no kind: `link_gre6.c` parses the erspan words and sends `ERSPAN_VER` for all three kinds.
+- **KP4-T02's tables grew.** Two built corner rows stand beside the corpus rows the plan named (the swapped sport, the `CAP` bits), so each check names its bytes. Four rows were added: an IPv4 remote, gre's pmtudisc, `external`, and `fwmark inherit`.
+- **ipip's default proto is any.** `iptunnel_parse_opt` sends `PROTO` 0 unless a mode word is given, and `ipip_tunnel_validate` keeps it, so a plain ipip reads back `"proto": "any"`; the plan's first parse row said `ipip`.
+- **isatap on ipip is an option error.** `ip` falls through to its help for `isatap` on ipip (rc 1); `EncodeIptunInfoData` refuses it with `ErrKindSettingOption`, as `EncodeGreInfoData` refuses erspan words on gre. `mode ip6ip` on ipip is `invarg`'s range error, `ErrKindSettingRange`.
+- **`IptunInfo` is shared with ip6tnl.** It carries ip6tnl's `ENCAP_LIMIT` and `FLOWINFO`, and reads `FLAGS` at the width the kernel sent: 2 bytes for sit, 4 for ip6tnl. KP4-T04 adds ip6tnl's encoder.
+- **ip6tnl doesn't seed the encap.** The entry above that lists ip6tnl among the prefetch's byte-swapped ports is wrong for it: `ip6tunnel_parse_opt` reads no `ENCAP_*` from the prefetch, so a set resets the encap to type 0, `CSUM6` and ports 0, and there is no port to swap. gre, gre6 and iptnl still swap one.
+- **The ip6 tunnels share their flag state.** The encap limit, flow info, `IP6_TNL_F_*` flags and fwmark, and the words that tie them together (`encaplimit none`, the `inherit` forms), are `ip6Tnl`, embedded by `EncodeGre6InfoData`'s and `EncodeIp6tnlInfoData`'s encoders; `EncodeIp6tnlInfoData` takes `IptunSetting`, with the four ip6 options added, and refuses ipip's and sit's tos, pmtudisc, isatap and 6rd words with `ErrKindSettingOption`.
+- **KP4-T04's tables grew.** The inherit-flags parse row is three rows, one per flag; the encode table adds the mplsip mode and sit's isatap as negatives and `no settings` as a boundary, and its set-resets-the-encap row is built (a `cur` with a fou encap) so the reset is visible in the bytes.
+- **The xfrm interface's names carry `Link`.** `xtcpnl_xfrm.go` and `XfrmInfo` are the NETLINK_XFRM family's (an SAD info message), so the kind's decoder is `XfrmLinkInfo` and `ParseXfrmLinkInfoData` in `xtcpnl_xfrm_link.go`, with `EncodeXfrmLinkInfoData`. `LinkInfo.Xfrm` keeps the short name.
+- **The vti encoder takes the family.** `vti_parse_opt` and `vti6_parse_opt` differ only in it, and an endpoint of the other family is `ip`'s refusal, so `EncodeVtiInfoData` takes a `v6` bool, as `EncodeIptunInfoData` takes `sit`. The plan's signature had none.
+- **An xfrm if_id of 0 is a range error.** `xfrm_parse_opt` refuses it with `invarg` inside the loop, so `EncodeXfrmLinkInfoData` returns `ErrKindSettingRange` for it; `ErrKindSettingMissing` is kept for no `if_id` at all.
+- **KP4-T05's tables match the built rows.** The plan's `vti/add_default` row said local `any`; that row names a local, so it expects 10.0.0.2 and `add_ikey_okey` carries the `any`. The parse table is two tables, one per decoder; each encode table gains `no settings`, vti's an IPv6 remote, a key past 32 bits and `remote any`, xfrm's a dev with `external`, an if_id of 0 and the link's place. The last-key-wins row is built from its words, so its bytes are named.
+- **KP5 is four tasks:** hsr; netkit; vrf, vrf_slave and vxcan; batadv with the five kinds `ip` has no parser for. No KP5 parser prefetches, so the encoders take settings alone; netkit's and vxcan's peer halves share `EncodeVethPeer`'s nest. vxcan and batadv have no `fill_info` and the parser-less kinds no `INFO_DATA`, so their tasks test that nothing is there rather than decode it.
+- **KP5-T01's word-order row is built out of id order.** `add_abbrev`'s words (`sl d0 slave2 d1 s 7 v 1 p 0`) already come in attribute-id order, so a mutant sorting the attributes by id passed it; the row is built from `s 7 sl d0 p 0 v 1 slave2 d1` instead. The `LinkInfo` negative is an ifb, since no corpus row dumps a dummy as its own device.
+- **netkit's peer nest is `putPeerNest`.** `EncodeVethPeer`'s nest body moved into `putPeerNest(ab, atype, peer)`, which netkit calls with `IFLA_NETKIT_PEER_INFO` and KP5-T03's vxcan will with `VXCAN_INFO_PEER`; veth's bytes are unchanged.
+- **netkit's empty `INFO_DATA` is not none.** `peer` alone makes `ip` open and close `IFLA_INFO_DATA` with nothing in it, so `EncodeNetkitInfoData` returns an empty, non-nil slice for it and `nil` only for no settings; the test tells the two apart.
+- **KP5-T02's tables match the built rows.** The encode table gains a policy with no name (`ErrKindSettingRange`), a peer half with no `peer` word (`ErrKindSettingMissing`), and a built `PEER_INFO`-order row, since the PEER_INFO-first mutant survived every corpus row; the peer-flags, `peer` alone and peer-mode rows are built rather than read from the corpus. The `LinkInfo` negative is a vxcan, since a veth carries no `INFO_DATA` to misdecode.
+- **vrf keeps its decoder where it is.** `vrfTableAttr` and the `LinkInfo.VrfTable`/`VrfPortTable` fields stay beside `setLinkInfoNest`; `xtcpnl_vrf.go` holds only the encoder, and the benchmark times `vrfTableAttr`. The `LinkInfo` and `setLinkInfoNest` comments that said only vrf and bond are decoded now point at the per-kind fields.
+- **vxcan's encoder takes the peer alone.** `vxcan_parse_opt` refuses any first word but `peer` and hands the rest to `iplink_parse`, so `EncodeVxcanInfoData(peer *VethPeer)` has no settings; a nil peer is no option words, which `ip` sends with no `INFO_DATA` (`iplink.c` calls `parse_opt` only when words remain) (`add_no_option`, `add_up`).
+- **KP5-T03's tables match the built rows.** The vrf two-tables row is built out of order (`table 20 table 10`) so an encoder that sorted or kept only the last would fail; `add_table_twice` stays a corpus row. vxcan gains `no option words`, and its bare-word and flags rows are built. `TestKindSlaveDataAbsent` checks `set_type`'s readback beside `set_master`'s.
+- **batadv's encoder takes names, not a table.** `batadv_parse_opt` sends each `ra` word unchecked, so `BatadvSetting` holds the name; a NUL inside one is `ErrKindSettingRange`, since no argv word can carry it. There's no decoder: batadv has no `fill_info`, so `LinkInfo` gains nothing.
+- **KP5-T04's tables match the built rows.** The two-names row is built out of order (`ra BATMAN_V ra BATMAN_IV`), and the case row is built; `add_ra_twice` and `add_ra_lowercase` stay corpus rows. `TestKindsWithoutData` gains a vcan dump, and its negative row is one subtest per request (46).
+- **KG0 is planned now, and each later KG phase when the one before it closes.** The KG phases run in group order, KG0 to KG5. KG0 is two tasks, since its matrix rows need two consecutive clean VM runs before they're gated and the parser doesn't.
+- **KG0's exit statuses follow `ip` through a link-only sentinel.** The earlier decision says KG0 matches the status as well as the text. goip exits 1 on every `ErrInvalidArgument`, and `invargErr`, `dupargErr` and `incompleteErr` are shared by most of goip's other objects, so KG0-T01 adds `ErrLinkUsage` (exit 255) and wraps only `parseLinkArgs`' `exit(-1)` refusals. The existing link refusals move from 1 to 255 with it. The bond parser keeps 1 until KG5 reaches the kind parsers' statuses.
+- **The `ip`-refused `inet` rows aren't matrix rows.** A write row needs goip to exit 0, so the 7 refusals are held offline by `TestLinkSetInetRefusals`, as `nodev` is by `TestRouteWriteNodevCorpus`. The two the kernel refuses are matrix rows, compared on the request.
+- **The `inet` replay uses 7.2.0's lookup mask.** The 7.3.0 corpus was captured with `ip` 7.2.0, whose `ll_link_get` sends `IFLA_EXT_MASK` 0x109 (`RTEXT_FILTER_NAME_ONLY`, `de91e928`). `main_test.go` sets `req.LLMapNameOnly` false for the 7.1.4 fixtures, so the KG0-T01 tests set it true for their run, as `corpus_7_3_0_test.go` does. The goip binary already defaults to 7.2.0's mask.
+- **KG0-T01's tables match the built rows.** The replay table names each of the 11 rows, `inet_medium_id_neg2` beside `inet_rp_filter_over` as a kernel refusal built anyway. `TestErrLinkUsageExitCode` is added to pin `exitCodeOf`'s arm order, since `ErrLinkUsage`'s refusals also wrap `ErrInvalidArgument`.
+
+**2026-10-25:**
+- **A section run gates a row; a full run comes before a push.** `goip-parity --section link,addr` (`commands` and `compare` both take `-section`, the runner `--section`) captures and compares only those ip objects' rows, a row's section being the first word of its argv that isn't an option. Two consecutive clean runs of a row's own section gate it. One clean full run comes before any push or PR, since goip's code is shared across sections. A filtered report prints `GOIP_PARITY_SECTION <list> (<n> of <total> rows)` and the runner's verdict says it isn't the full gate, so the two can't be mistaken for each other. Capture is about 5 s a row, so `link`'s 48 rows take minutes where the table's 518 take about 45.
+
+- **The inet rows keep their own slug prefix.** They're `link_inet_*`, not in the `link_write_*` cohort, so `TestInetMatrixRows` can find them by prefix and `--section link` still holds them, the section being the argv's object and not the slug.
+- **`compare_write_test.go` maps the inet rows to the 7.3.0 rtnl corpus.** Their fixtures are KC1's `7_3_0/link-write/rtnl/inet_*`, so `corpusWriteRow` reads a `link_inet_<x>` row from `inet_<x>` there (`tdRtnl730`), not from the 7.1.4 `rtnl` directory the other rtnl write rows use.
+- **KG0-T02's rows are the first gated by a section run.** The full table ran first (V135) and `--section link` second (V136), so they meet the earlier rule (two consecutive clean runs) and the new one (a section run, then a full run before a push) both. `TestInetMatrixRows` gains `positive: every row is gated`, since nothing in the plan's table failed if the allowlist lost a row.
+- **KG1 is five tasks.** The words and the renders split by kind, since bridge_slave adds a resolver to each (`backup_port`'s get when parsing, its name when rendering), and the matrix rows are their own task for the two VM runs.
+- **The bridge parsers match `ip`'s statuses now.** `invarg` and `incomplete_command` exit 255 through `ErrLinkUsage`, returned refusals 1, as KG0's link refusals do; the bond parsers wait for KG5.
+- **goip prints a refusal's first line, not `ip`'s usage.** `unknown command` is followed by `explain()`'s usage in `ip`; goip prints the first line only, as for bond, and the refusal tables compare that line.
+- **The bridge `-d` text is held offline.** The matrix compares stdout through its facets, not the kind text, and the timers move between any two runs, so the sidecar tests, each against its own pcap, are the text and JSON oracle; the read rows check the device's other lines and that `-d` no longer refuses.
+- **`kindData` and `buildLinkWrite` take `errOut`.** `parse_one_of`'s prefix warning goes to stderr and the parse goes on, so the kind parsers need the command's stderr; `linkWrite` passes `c.errOut`, the tests `io.Discard` or a buffer.
+- **goip has `ll_proto_a2n`.** `internal/goip/ll_proto.go` is `lib/ll_proto.c`'s table in its order, for `vlan_protocol` now and the vlan kind's `protocol` in KG2; names compare without case, as `proto_a2n`'s `strcasecmp` does.
+- **The bridge argv table is checked against the corpus.** The KC2 rows record no argv, so `bridgeCorpusArgv` writes each row's out from `kind-write-corpus.exp`, and `TestBridgeCorpusArgv` fails if a corpus row has no argv or an argv no row.
+- **`nobackup_port` is tried after the bridge_slave chain.** It has no `BridgeSlaveOptions` row, so `bridgeChain` can't find it; tried after the chain it picks the same words as in its place, since no keyword before it matches a prefix of it longer than `n`, and `n` is `neigh_suppress`'s. `TestBridgeSlaveParseChain`'s `no` row holds that.
+- **The bridge_slave refusals send p0's get.** `iplink_parse` resolves `dev p0` before `bridge_slave_parse_opt` runs, so each refusal row expects its capture's lookups, p0's and, for `backup_port nosuch`, nosuch's, and no write.
+- **The slave kinds have their own `-d` gate.** `IFLA_INFO_SLAVE_KIND` names the master's kind, so a bridge port's is `bridge`, but its print_opt is `bridge_slave_print_opt`; `renderableSlaveInfoData` kept ports refused until KG1-T04 while `renderableInfoData` admitted the bridge.
+- **The `ll_proto` table lives in `pkg/xtcpnl`.** The renderer needs `ll_proto_n2a` and can't import goip, so `LLProtoNames` and `LLProtoN2A` move to `xtcpnl_ll_proto.go`; goip's `llProtoA2N` reads the same table.
+- **The `show dev` replays pair each get with its reply.** `ip link show dev br0` sends `ll_name_to_index`'s get on a socket of its own and then `iplink_get`'s, both by name, and a dump replay matches both replies. KG1-T03 held the replay to the main socket with `GOIP_REPLAY_PORTID`; KG1-T04 replaced that with `runKindShow`, whose `linkReplay` answers each get with the reply that followed it in the capture and records the gets, so a test can hold them to the capture's requests.
+- **The 7.1 mesh sidecar lacks `stp_mode`.** goip's `-d -4 addr show` of the mesh namespace differs from `mesh/ip_addr_v4_n` in `gc_timer`, which moved, and `stp_mode`, which 7.2.0 prints and the 7.1 `ip` that wrote the sidecar doesn't. goip follows the pin; the row checks the status and the sidecar's tokens.
+- **`mcast_fast_leave` is a text-only call.** bridge_slave_print_opt prints `IFLA_BRPORT_FAST_LEAVE` twice, the second time with `print_string(PRINT_FP, …)`; `KindData.addText` records a call with no JSON key, which `MarshalJSON` skips, rather than a special case in the renderer.
+- **A bridge port with no slave data is `"info_slave_data":{}`.** print_linktype opens the object whenever the slave kind has a print_opt, before print_opt's `if (!tb) return;`, so goip's empty `KindData` marshals as `{}`, as the veth/bridge row of `TestLinkDetailJSONKeys` now expects.
+- **The mesh rows render now.** With both bridge print_opts in, `-d link show` and `-d addr show` of the mesh topology exit 0; the link row checks the status and the sidecar's tokens, not the whole text, since gc_timer, stp_mode and nlmon0's promiscuity differ from the 7.1 sidecar.
+- **Two bridge rows are respelled for the allowlist.** A command's `Name` is its allowlist key and its argv, so two corpus rows whose argv another row already has, `set_stp_mode_busy` and `set_not_enslaved`, are `link set dev br0 type bridge stp_mode user` and `link set p0 type bridge_slave cost 10`. `dev` is `iplink_parse`'s optional word, so each sends the same request as its corpus row, which `TestCompareWriteRow` holds.
+- **The bridge rows read the 7.3.0 kind corpus.** `corpusWriteRow` maps a `link_bridge_<x>` or `link_bridge_slave_<x>` row to `7_3_0/link-write/kinds/<kind>/<x>` (`tdKinds730`), trying the slave prefix first, since a bridge_slave slug has both.
+- **KG1 closes on section runs alone.** Its 96 rows were gated on two `--section link` runs; the full run the rule asks for comes before the next push, not before the gate.
+- **KG2 starts with the `link` keyword.** Every KC3 row is stacked on d0 with `link d0`, which goip refused as unimplemented, so KG2-T01 adds it with the vlan words. The vlan corpus is its oracle, and hand-built dummy rows cover what no capture reaches.
+- **KG2 is five tasks, one per parser.** macvtap and ipvtap share macvlan's and ipvlan's parsers and print_opts, so they're never tasks of their own. The three renders are small enough to be one task, and the matrix rows are their own task for the two VM runs.
+- **macvlan's bad op prints its usage line.** goip prints a refusal's first line and no usage, but `macaddr bogus`'s only text is the usage, so goip prints that line, with the kind's name in it.
+- **`ll_addr_a2n`'s warnings are output.** `macaddr set` reads addresses until one fails, and the failing word's warning reaches stderr even when the command succeeds. goip's `llAddrA2N` reports only success, so KG2-T02 adds a variant that names the part `ll_addr_a2n` printed, or none when it failed silently on a length.
+- **The plan's vlan flag-order mutant moved.** "The flags in argument order" is `EncodeVlanInfoData`'s, which KP2 held; `parseVlanArgs` only reads values, so KG2-T01's mutant reads `on` as off instead. KG2-T02's "the mode in argument order" is the same, so its mutant tries `nodst` before `nopromisc`.
+- **A `macaddr set` re-reads its last word cut.** `ll_addr_a2n` writes a NUL over the first `:` in place, so the word a set stops on goes back to the chain cut there, as `parse_mapping`'s does for vlan. goip copies the cut (`llAddrCut`) rather than refusing the word, so `mode:x` after a set is a `mode`, and seven parts leave `02`, an unknown option.
+- **A silent `ll_addr_a2n` refusal gets a goip text.** `ip` exits 1 with nothing on stderr for an add or del address of the wrong length; goip prints `"<word>" is not a 6-byte lladdr`, since its refusals are never empty, and the refusal row holds it apart from `ip`'s `invalid lladdr`.
+- **A short protocol or flags attribute prints past.** `vlan_print_opt` reads `IFLA_VLAN_PROTOCOL` and `IFLA_VLAN_FLAGS` without a length check; KP2's decoder drops either when it is short, so goip prints `802.1q` or no flags where `ip` would read past the attribute. The kernel never sends a short one.
+- **The kind rows share one slug table.** `kindRowKind` maps a `link_<kind>_<x>` slug to `7_3_0/link-write/kinds/<kind>/<x>` for bridge, bridge_slave and the five VLAN family kinds, trying bridge_slave before bridge; `bridgeRowKind` is that table cut to KG1's two kinds, so `TestBridgeMatrixRows` is unchanged.
+- **`add_on_busy_lower` is respelled.** It shares `add_default`'s argv, so its row is `link add link d0 dev i0 type ipvlan`; `dev` is `iplink_parse`'s optional word, and the row sends the same request, which `TestCompareWriteRow` holds.
+- **KG2 closes on section runs alone,** as KG1 did. The full run comes before the next push.
+- **KG3 is five tasks.** vxlan and geneve are large enough to be a task each; bareudp, amt and gtp are small enough to share one. The five renders are one task, and the matrix rows are their own task for the two VM runs.
+- **goip makes `ip`'s checks itself.** The KP3 encoders refuse with three errors where `ip` has a text per case, so each parser runs `ip`'s checks in `ip`'s order and returns `ip`'s text. The encoders' refusals stay as a backstop that no goip argv reaches.
+- **`ip -4` and `-6`'s default vxlan group is implemented.** With no address given, `ip` sends `IFLA_VXLAN_GROUP` 0.0.0.0 or `GROUP6` `::` for a preferred family. KP3 left it out of the encoder, so KG3-T01 adds `VxlanOptionDefaultGroup`, which the encoder places, rather than refusing `-4`. No capture has it; hand-built rows hold it.
+- **A kind's `dev` exits 255.** vxlan's and amt's `dev` is `exit(nodev)`, 255, where `iplink_parse`'s `link` returns `nodev`, 1, so KG3-T01 adds `nodevExitErr` beside `nodevErr`.
+- **vxlan's dstport warning goes to stderr.** An add with neither `dstport` nor `gpe` prints four lines and still succeeds. goip prints them and exits 0; the matrix doesn't compare stderr, and the replay row holds the text.
+- **amt's bad mode prints its usage line,** as macvlan's bad op does: the usage is its only text.
+- **`-d -d` is not `-d` for vxlan.** `vxlan_print_opt` shows its bool options at their defaults when `show_details > 1`, the one such site at `v7.2.0`, so `options.go`'s note that no site tests the count was wrong once vxlan renders. KG3-T04 carries the count to the renderer, and a `-d -d link show dev vx0` read row gates it.
+- **amt's mode past relay prints `unknown`.** `ip` indexes past its two-name table. `amt_validate` refuses such a mode, so no device has one, and goip prints gtp's word for a role past its table.
+- **Two geneve rows are respelled.** `add_duplicate` and `add_after_external` share an argv, as do `set_local_same` and `set_local_new`, so `add_after_external` and `set_local_new` take `iplink_parse`'s optional `dev`, as KG1's and KG2's respellings did.
+- **vxlan's multicast test reads the bytes.** `set_address_type` tests `IN_MULTICAST` and `IN6_IS_ADDR_MULTICAST` on the address as given, so a v4-mapped `::ffff:239.1.1.1` is a unicast remote. netip's `IsMulticast` unmaps it, so the encoder's group and group-without-dev checks now use `vxlanMulticast`.
+- **An empty vxlan address is refused.** `any` or `all` after an address of the other family has a family and no bytes, and `ip` sends the attribute empty. A `VxlanSetting` can't hold that, so goip refuses it as not implemented; no capture has it.
+- **An `if<n>` dev past INT_MAX is nodev.** `ll_name_to_index` returns it negative and `ip` sends it; goip refuses it with `exit(nodev)`'s text.
+- **The not-implemented example is ipoib.** `TestBuildLinkWrite`'s row for a kind goip doesn't build was vxlan; ipoib is out of scope, so it holds the row from now on.
+- **`set_op` is an RTM_NEWLINK without NLM_F_CREATE,** as `ip` computes it, so a kind's checks see a `link delete … type vxlan` as an add.
+- **The UDP overlays share their words.** `link_kind_args.go` holds what vxlan and geneve spell alike: the keywords, `check_duparg`'s bitmask, `set_address_type`'s address types, and the id, ttl, tos, df and flowlabel readers, whose invarg texts are the same in both files. Each kind keeps its own chain and checks. `overlayData` keeps `kindData` under funlen.
+- **geneve's encoder reads multicast from the bytes too.** It refused a v4-mapped multicast remote that `ip` sends as `REMOTE6`, as vxlan's did, so both now use `kindMulticast`.
+- **amt's `any` after a discovery is not implemented.** With a discovery's family set, `get_addr` gives `any` or `all` an empty address, which `ip` sends as an empty attribute; an `xtcpnl.AmtSetting` can't hold one, so goip refuses it as not implemented.
+- **amt's `dev` is vxlan's.** A name that doesn't resolve, or an `if<n>` past INT_MAX, is `exit(nodev)`, 255, through `nodevExitErr`.
+- **The small overlays' refusal rows are named by kind.** KC4's corpus reuses row names across bareudp, amt and gtp, so the test names each `<kind>/<row>`.
+- **missarg has one helper.** bareudp's missing dstport and ethertype go through `missargErr`, `ip`'s `Error: argument "<key>" is required` at 255.
+- **goip's typed show path refuses `-d -d`.** Run carries the `-d` count to the link render, but a `ShowRequest` holds `-d` as a bool, so `ResolveShow` refuses a count above one, as it refuses `-s -s`, rather than answer `-d -d` with `-d`'s render.
+- **vxlan's and amt's `dev` is a get.** `ll_index_to_name` on the lower device sends `RTM_GETLINK` for an index not cached, so `resolveLinkRefs` resolves it after bond's indexes and before bridge_slave's `backup_port`, in `print_linktype`'s order.
+- **amt's mode past relay prints `unknown`.** `ip` indexes past `modename`; goip prints gtp's word, and `amt_validate` refuses such a mode, so no device carries one.
+- **The VLAN family test names its kinds.** With the UDP overlays in `kindRowKinds`, `TestVlanFamilyMatrixRows` keeps the rows whose kind is one of its five, where it had dropped bridge's two.
+- **Each kernel-refused row says why.** A rc 2 row's comment is the last line of its `ip.err`, the kernel's extack or `RTNETLINK answers` text.
+- **KG3 closes on section runs alone,** as KG1 and KG2 did. The full run comes before the next push.
+- **vxlan's `ageing` rows split the keyword.** misspell holds string literals to US spelling, so the three rows that carry it build their names and slugs from `vxlanAgeingCst`, and the earned list splits it, as KG1's bridge rows do for `ageing_time`.
+- **KG4 is nine tasks.** The fallback-device fix comes first, since every tunnel row needs it. The words split by `ip`'s parser files: gre, gre6, iptnl, ip6tnl, and vti with xfrm. The renders split into the gre kinds and the rest, and the matrix rows are their own task for the two VM runs.
+- **goip-parity sets the fallback sysctl before its first row.** `late_setup` set it only at the first row that isn't `route`, which a `--section link` run never reaches and a full run reaches after every link row. So the first row of each tunnel kind would load its module, and give every later namespace an any/any fallback device. The sysctl step moves into `nltopo::no_fallback_tunnels`, which the driver calls before the loop and `late_setup` still calls first.
+- **The prefetch is built once.** Every tunnel parser but xfrm's reads the device back on a set. KG4-T02 adds the 32-byte get with no `IFLA_EXT_MASK` and the `get_failed` checks, and the later tasks reuse them.
+- **The prefetch runs without `NLM_F_CREATE`.** That is `ip`'s test, so `ip link delete … type gre <words>` prefetches too, and goip keys it on `!verb.create()`, not `setOp()`.
+- **The prefetch reads raw `IFLA_INFO_DATA`.** `ip` reads the reply by its own parser's ids whatever the reply's kind, and fails on an endpoint of the wrong length or family. goip checks the raw endpoint lengths as `get_addr_rta` does. A reply outside the parser's kinds that passes them is not implemented, since `ip` would seed from another kind's attributes.
+- **The prefetch's two `ip` bugs are copied.** The byte-swapped encap port and vti's low-byte `LINK` go back as `ip` sends them, as the KP4 encoders already do.
+- **A tunnel's `help` is its usage line.** No tunnel parser has a `help` word, so `ip` prints the usage for it as for any unknown word, exit 1. goip prints the usage's first line, where KG3's kinds, which do have a `help` word, refuse it as not implemented.
+- **Five tunnel cases are not implemented:** sit's `6rd-reset`, which segfaults `ip` 7.2.0; ip6tnl's `encaplimit` with a value that isn't a u8, which sends an uninitialized byte; sit's `6rd-prefix any` and `6rd-relay_prefix any`, which send an empty address no `IptunSetting` holds; and a prefetch reply of a kind outside the parser's.
+- **gre's and iptnl's parsers take `cur`.** gre's broadcast check and iptnl's ttl check read the seeded endpoints and values, before `external`, so the parser makes them with `ip`'s text and the encoders' refusals stay a backstop.
+- **Three tunnel rows are respelled.** `ip6gretap/add_beside_ip6gre`, `ip6tnl/set_collide` and `xfrm/set_drop_dev` share an argv with another row, so each takes `iplink_parse`'s optional `dev`.
+
+**2026-11-01:**
+- **gre's chain spells three words as constants.** goconst counts a literal across the package, so `seq`, `nopmtudisc` and `pmtudisc`, which l2tp's and xfrm state's words also use, are `greSeq`, `greNopmtudisc` and `grePmtudisc` in `link_gre_args.go`.
+- **The prefetch's tests add two rows.** `TestTunnelPrefetch` holds a reply with `IFLA_LINKINFO` but no `IFLA_INFO_DATA` beside the plan's no-`IFLA_LINKINFO` row, since `ip` fails on each separately, and the plan's seeded-multicast refusal moved there from `TestLinkGreRefusals`, as it needs a built reply. `TestParseGreArgs` adds `d d0`, the `dev` abbreviation resolving.
+- **KG4-T03: gre and gre6 share their chain's head.** `greCommonChain` holds the key, seq and csum words, the endpoints, dev and ttl's and tos's aliases. gre's `[no]pmtudisc` moves from before `remote` to after `dsfield`. That is the same chain, since none of the words between starts with `n` or `p`. The tos aliases are gre6's tclass, read in hex; `fl` is strcmp, so `f` is a usage error (the row V199's `fl` mutant needed).
+- **KG4-T04: a 6rd prefix's length is bound-checked, not suppressed.** `get_prefix`'s bitlen is an `int`; goip refuses one below 0 or past the address's width before the `uint64` conversion, so gosec needs no exclusion. A 6rd prefix of `any`, `all` or `default` (bitlen -2) is `ErrNotImplemented`: `ip` parses it and sends nothing, a case with no capture.
+- **KG4-T07: the decoder keeps each endpoint's length.** `tnl_print_endpoint` reads the attribute's length as the family (4, 16, else `unknown`), and a `netip.Addr` can't say what arrived, so `GreInfo` gains `LocalLen` and `RemoteLen` (the last attribute's) and `HasLocal` and `HasRemote`. KG4-T08 adds the same to `IptunInfo` and `VtiInfo`.
+- **KG4-T08: gre6 and ip6tnl share their flow words.** `tnl6Flow` (encaplimit, tclass, flowlabel and dscp) and `tnlFwmark` move to `link_tunnel.go`, so the two print_opts' identical blocks are one. xfrm's link is decoded but never printed, as `xfrm_print_opt` has it.
+- **KG4-T08: the `-d` refusal is tested on hsr and netkit.** Its old corpus, the 7_1_4 tunnel topology, renders in full now. hsr's and netkit's readbacks are single gets, which `GOIP_REPLAY` can't replay, so the new test drives `runLink` through `linkReplay` as the kind tests do.
+- **KG4-T09: the prefetch's volatile fields are control noise, not failures.** The 32-byte prefetch's reply is a whole `RTM_NEWLINK`, so its IPv6 cacheinfo timestamps and gretap's random MAC differ between `ip`'s two control legs. The comparator already suppresses what the control legs disagree on, so `CONTROL_NOISY` rises from 4 to 84 and every row still passes; no per-kind suppression is added.
+- **KG5 is seven tasks.** The kinds with no parser need only dummy's else arm and two link keywords, so they come first. The words split by `ip`'s parser files: hsr, netkit, then vrf, vxcan and batadv. The bond statuses KG0 left are a task of their own, the two renders another, and the matrix rows are their own task for the two VM runs.
+- **54 of KC6's 122 requests already match goip.** A throwaway replay found them: every kind with no words, a set of only `type K`, and the `master`, `nomaster` and `mtu` rows. Each task's table still lists every row of its kinds, so a regression in a matching row is caught.
+- **hsr's `version` and `proto` are copied as written.** goip sends any u8, as `ip` 7.2.0 does, and `version 2` is the kernel's refusal (`hsr/add_version_2`, rc 2). KP5's encoder already takes any u8.
+- **sit's `6rd-reset` stays `ErrNotImplemented`.** KG4-T04 refuses it; `ip` 7.2.0 crashes on it, so there is no behavior to match.
+- **Four help rows stay `ErrNotImplemented`.** `ifb/add_help_abbrev`, `team/add_help`, `netkit/add_peer_help` and `vxcan/add_peer_help` print `ip link`'s whole usage and exit 255, which goip refuses for dummy and `ip link help` too.
+- **vxcan's usage goes to stderr in goip.** `ip` prints it to stdout; goip prints every refusal as `goip: <text>` on stderr. The status, 1, matches, and the three rows' tables check the text against `ip.out`.
+- **Six KG5 rows are respelled.** `batadv/add_duplicate`, `vrf/add_shared_table`, `team/set_enslave_again`, `vrf_slave/set_nomaster`, `team_slave/set_unenslaved` and `vcan/set_mtu_up` share an argv with another row, so each takes `iplink_parse`'s optional `dev`.
+- **KG5-T01 adds two tables beside the plan's.** The help rows and the queue counts' accepted values are `buildLinkWrite` calls rather than replays (`TestLinkNoParserHelp`, `TestLinkQueueCounts`), since no capture holds them; the no-parser kinds are a case list in `kindData`'s switch, not a named set. Its built refusal `numtxqueues type ifb` records that `ip` reads `type` as the count.
+- **KG5-T03's mutants are what goip's structure allows.** goip parses the peer into its own `linkParsed`, so "the device's flags not saved" and "the peer's flags left on the device" from the plan become the device's flags copied into the peer and the peer's flags dropped; both are killed.
+- **KG5-T04 differs from its plan in three places.** `rtnlNameA2N` over `routeTableNames` was already a helper (`route_write.go`), so nothing was factored out of `routeParseState.table`. vrf's and batadv's parsers share `link_vrf_args.go` rather than a `link_batadv_args.go`. And veth's peer `type`, which goip refused at 1, is `duparg`'s 255 in `ip`; vxcan shares the code, so both now exit 255, with a row for each.
+- **KG5-T05 sends a negative ifindex rather than refusing it.** The plan's corner row had a resolver's -1 refused. `ip` tests `primary`'s, `active_slave`'s, `master`'s, `vrf`'s and hsr's ifindex only for 0 and copies the int into the u32, and `ll_idx_a2n`'s `if%u` can return one past `INT32_MAX`, so goip sends the bits (`TestLinkIfindexBits`); KG5-T01's `vrf` and KG5-T02's hsr words, which refused one, now do the same. Six `//nolint:gosec` went, not two: the master arm, `intAttr`, the bond resolver, `ll_idx_a2n`'s two and the bond s32.
+- **KG5-T06 needed the slaves' gets.** `hsr_print_opt`'s `ll_index_to_name` sends a get for each slave and the interlink, so `resolveLinkRefs` sends them, in print order, unless a short attribute makes the print_opt return first. The decoder already kept `Short`, so it gained no raw lengths. The two netkit and hsr files are one, `render/link_hsr.go`.
+- **KG5-T07 differs from its plan in three places.** team_slave's read rows are `-d link show d0` and `-d -j link show d0`, without `dev`, since vrf_slave's read rows already spell `dev d0`. The plan's corner row checked one floor that counts a lookup, `vrf_slave/set_vrf`'s 8; the row covers the other two, `hsr/add_interlink` (8: the slaves' and the interlink's gets) and `netkit/set_peer_name` (6). And no module went into `nltopo::late_modules`: each kind's first row, which loads its module, passed on all three legs in both runs (V241, V242).

+# goip ↔ `ip` parity: link kinds and iproute2 7.2.0's `link set inet`
+
+## Status
+
+**Last updated:** 2026-11-02
+
+**Summary:**
+- [goip-parity-gaps.md](goip-parity-gaps.md) is finished. C0 to G7 are on `main` (#280, `31bff973`), and the parity VM passes 507 of 507 rows against `ip` 7.2.0.
+- That plan's inventory counted objects and verbs, not link kinds:
+  - iproute2 7.2.0 has 39 `ip/iplink_*.c` and `ip/link_*.c` files.
+  - goip covered a handful of the kinds they define when this plan was written; it now covers every in-scope kind in [the inventory](#the-kind-inventory) (see [Where goip stands](#where-goip-stands)).
+  - Every other kind is refused rather than wrongly answered.
+- This document plans the rest:
+  - every link kind a VM can create with only a module;
+  - the one new write the 7.2.0 pin brings, `ip link set dev X inet …`.
+- The tiers are the same as before, in the same order: captures (KC), then parsers with table tests and benchmarks (KP), then goip and the matrix (KG).
+- **Done (2026-11-02):** KC0 to KG5 are closed, and goip-parity's table is 1246 rows. [Where goip stands](#where-goip-stands) lists what each kind landed with.
+
+**Progress** is tracked in [goip-link-kinds-status.md](goip-link-kinds-status.md): the next action, the phase states, the task checklist, the verification ledger and the decision log. This document changes only when a task refines its own plan, or when a phase close updates the [inventory](#the-kind-inventory).

+## Reference sources
+
+These are the trees [goip-parity-gaps.md](goip-parity-gaps.md#reference-sources) uses, and they are read-only in the same way. Two things differ:
+- **The `ip` pin is 7.2.0** (`nix/upstream-pins.json`). Read it with `git -C ~/Downloads/iproute2 show v7.2.0:ip/<file>`. Line numbers here are from `v7.2.0`. The checkout is a few commits past the tag (`v7.2.0-34`), so the tag, not the working tree, is the source of truth.
+- **Kernel line numbers** are from the local 7.3.0-rc6 tree, as before. The guest kernel is `linuxPackages_latest` (`nix/microvms/mkVm.nix`), 7.3.0 at KC0.
+
+## Where goip stands
+
+Since KG5 closed, goip parses the words of every kind in the inventory and renders the `-d` output of every kind KC captured, matched against `ip` 7.2.0 on KC's corpus and in goip-parity's VM rows.
+
+| kind | decode (`pkg/xtcpnl`) | encode | goip args | `-d` render |
+|---|---|---|---|---|
+| bond, bond_slave | `xtcpnl_bond.go` | `encodeBondSettings` (`xtcpnl_link_write.go`) | `link_bond_args.go`; `ip`'s exit statuses since KG5-T05 | `render/link_bond.go` |
+| vrf, vrf_slave | the table id | `EncodeVrfInfoData` (KP5) | `link_vrf_args.go` (KG5-T04); `iplink_parse`'s `vrf NAME` (KG5-T01) | `render/vrf.go` |
+| dummy, veth | no `INFO_DATA` | veth's peer | `link add` with no options; veth's peer through `vethData` | no `INFO_DATA` to render |
+| bridge, bridge_slave (KP1) | `xtcpnl_bridge.go`, `xtcpnl_bridge_slave.go` | `EncodeBridgeInfoData`, `EncodeBridgeSlaveData` | `link_bridge_args.go`, `link_bridge_slave_args.go` (KG1) | `render/link_bridge.go`, `render/link_bridge_slave.go` (KG1) |
+| vlan, macvlan, macvtap, ipvlan, ipvtap (KP2) | `xtcpnl_vlan.go`, `xtcpnl_macvlan.go`, `xtcpnl_ipvlan.go` | `EncodeVlanInfoData`, `EncodeMacvlanInfoData`, `EncodeIpvlanInfoData` | `link_vlan_args.go`, `link_macvlan_args.go`, `link_ipvlan_args.go` (KG2) | `render/link_vlan.go`, `render/link_macvlan.go`, `render/link_ipvlan.go` (KG2) |
+| vxlan, geneve, bareudp, amt, gtp (KP3) | `xtcpnl_vxlan.go`, `xtcpnl_geneve.go`, `xtcpnl_bareudp.go`, `xtcpnl_amt.go`, `xtcpnl_gtp.go` | `Encode<Kind>InfoData` for each | `link_<kind>_args.go` for each (KG3) | `render/link_<kind>.go` for each (KG3) |
+| gre, gretap, erspan, ip6gre, ip6gretap, ip6erspan, ipip, sit, ip6tnl, vti, vti6, xfrm (KP4) | `xtcpnl_gre.go`, `xtcpnl_iptun.go`, `xtcpnl_vti.go`, `xtcpnl_xfrm_link.go` | `EncodeGreInfoData`, `EncodeGre6InfoData`, `EncodeIptunInfoData`, `EncodeIp6tnlInfoData`, `EncodeVtiInfoData`, `EncodeXfrmLinkInfoData` | `link_gre_args.go`, `link_gre6_args.go`, `link_iptnl_args.go`, `link_ip6tnl_args.go`, `link_vti_args.go`, `link_xfrm_args.go`, with the set prefetch in `link_tunnel_args.go` (KG4); sit's `6rd-reset` refused | `render/link_gre.go`, `render/link_iptun.go`, `render/link_vti.go`, `render/link_tunnel.go` (KG4) |
+| hsr, netkit, vxcan, batadv (KP5) | `xtcpnl_hsr.go`, `xtcpnl_netkit.go`; vxcan and batadv send no `INFO_DATA` | `EncodeHsrInfoData`, `EncodeNetkitInfoData`, `EncodeVxcanInfoData`, `EncodeBatadvInfoData` | `link_hsr_args.go`, `link_netkit_args.go`, vxcan through `vethData`, batadv in `link_vrf_args.go` (KG5) | `render/link_hsr.go`, hsr's and netkit's (KG5-T06); vxcan and batadv have no `print_opt` |
+| ifb, nlmon, vcan, team, team_slave | no `INFO_DATA` (KP5-T04 tests it) | no options | `link add` with no options; a word after the type is dummy's `Garbage instead of arguments` (KG5-T01) | no `INFO_DATA` to render |
+| every other kind | no | no | refused | refused |
+
+The two refusals left:
+- **`link add … type X <options>`:** `kindData` (`internal/goip/link_write.go:694`) returns `ErrNotImplemented` for a kind it has no case for (`:778`), which is now only the [out of scope](#out-of-scope) kinds. Four help rows, which print `ip link`'s whole usage, stay `ErrNotImplemented` too.
+- **`-d link show`:** `checkDetailSupported` (`internal/goip/obj_link.go:372`) refuses a device carrying `IFLA_INFO_DATA` that `renderableInfoData` (`:400`) doesn't accept, which is now only a kind outside the inventory.
+
+`ip link set dev X inet …` is in goip's keyword chain since KG0-T01 (`linkParseKeywords`, `(*linkParseState).inet`), over KP0's codec (`xtcpnl_inet_devconf.go`: `LinkAttrInetDevconf`, `ParseInetDevconfRequest`, `ParseInetDevconfValues` and the `InetDevconfParams` table). Its matrix rows are KG0-T02's.
+
+## The kind inventory
+
+One row per iproute2 file, at `v7.2.0`:
+- **ids:** the `link_util` ids the file registers.
+- **print:** the lines in its `print_opt`. "—" means it has none.
+- **attrs:** the members of the kernel's `IFLA_<KIND>_*` enum after `UNSPEC`, counting `PAD`.
+- **module:** what `modprobe` loads.
+- **hazards:** the `ll_index_to_name` calls (an ifindex printed as a name) and the `format_host` calls (an address printed through the resolver, which reverse-resolves only with `-r`).
+
+| group | file | ids | print | attrs | module | hazards |

+`ll_index_to_name` is the hazard that matters: a link, lower or port index printed as a name. goip's renderer already takes a `NameTab` for this (`render.kindData`), and each such field needs a row whose index names a device in the namespace and a row whose index names none.
+
+## What 7.2.0 adds
+
+**`ip link set dev X inet <param> <value> …`** (`ip/iplink.c:572-860`, the keyword at `:946-947`). It is the only new write on the pin.
+- **Layout:** `IFLA_AF_SPEC` → `AF_INET` → `IFLA_INET_CONF` → one u32 per `IPV4_DEVCONF_*`, keyed by the devconf id. Only the `IFLA_INET_CONF` nest carries `NLA_F_NESTED`.
+- **Keywords** are matched with `strcmp`, not `matches`, so there are no abbreviations.
+- **23 on/off params**, read with `parse_on_off`: forwarding, proxy_arp, accept_redirects, secure_redirects, send_redirects, shared_media, accept_source_route, bootp_relay, log_martians, arp_filter (`ARPFILTER`), disable_xfrm (`NOXFRM`), disable_policy (`NOPOLICY`), promote_secondaries, arp_notify, accept_local, src_vmark, proxy_arp_pvlan, route_localnet, bc_forwarding, ignore_routes_with_linkdown, drop_unicast_in_l2_multicast, drop_gratuitous_arp, arp_evict_nocarrier.
+- **9 numeric params**, read with `get_integer` in base 0 (so `0x` and leading-`0` octal are accepted): rp_filter, tag, medium_id, force_igmp_version, arp_announce, arp_ignore, arp_accept, igmpv2_unsolicited_report_interval, igmpv3_unsolicited_report_interval.
+- **The end of the list:** the first word that is no param is pushed back (`PREV_ARG`), and `iplink_parse` carries on with it.
+- **Errors:** a bad numeric value is `Invalid "<param>" value`. A missing value, or `inet` with no known param after it, is `incomplete_command`.
+
+**Kind options new in 7.2.0:**
+- bridge `stp_mode` (`IFLA_BR_STP_MODE`);
+- bridge_slave `neigh_forward_grat`;
+- geneve `local`, one keyword that sends `IFLA_GENEVE_LOCAL` or `IFLA_GENEVE_LOCAL6` by the address's family.
+
+They are rows in K1 and K3 like any other option.
+
+**maddress is not one of them.** `ip maddress` moved to `RTM_GETMULTICAST` in iproute2 `b8cdda55`, which is after the tag (`v7.2.0-34`). At the 7.2.0 pin, `ip/ipmaddr.c` still reads `/proc/net/dev_mcast`, `igmp` and `igmp6` (`:95`, `:136`, `:179`), so it stays class F until the next pin bump. [goip-parity-gaps.md](goip-parity-gaps.md#f-not-netlink-outside-pcap-parity) is corrected to match.
+
+## Out of scope
+
+Each exclusion is recorded in the [decision log](goip-link-kinds-status.md#decision-log).
+- **Kinds that need hardware or another creation path:**
+  - can (vcan takes none of its options, and a real CAN device is hardware);
+  - ipoib, dsa, rmnet, wwan, virt_wifi, which each need a lower device the VM doesn't have;
+  - netdevsim, which is created through sysfs, not rtnetlink.
+- **XDP:** `iplink_xdp.c`'s `-d` output makes a `bpf()` syscall per program, which nlmon can't see. It is class F.
+- **xstats:** it isn't a kind. `link xstats` is already a goip read (G1).
+- **maddress:** class F at the pin, as above.
+- **Applying goip-built writes:** goip's writes stay dry runs, as in every earlier write design.
+
+## The per-kind pipeline
+
+Bond is the template. A kind is done when each step below has landed and its matrix rows are gated:
+1. **Captures** (KC): `link add` with the defaults, `link add` with each option `ip` parses, `link set … type X <option>` where the kernel allows a change, and `link del`. Each is a row in `capture-link-writes.exp` or `rtnl-write-corpus.exp`, with readbacks through `link-write-readback.exp`: `ip -d link show`, `ip -d -j -p link show` and `ip link show`.
+2. **Option table** (KP): one row per option, `BondOptionSpec`'s shape (`pkg/xtcpnl/xtcpnl_bond.go`). The table drives the decoder, the encoder and goip's argument parser.
+3. **Decode** (KP): `Parse<Kind>InfoData`, and `…SlaveData` for a slave kind, plus a `LinkInfo` field and a branch in `setLinkInfoNest` (`pkg/xtcpnl/xtcpnl_ifinfomsg.go:952`).
+4. **Encode** (KP): `Encode<Kind>InfoData`, following `putBondSetting` (`pkg/xtcpnl/xtcpnl_link_write.go:233`), and the kind in `LinkKindDataType` (`:109`).
+5. **Parser tests** (KP): a table-driven test whose positive rows are the step 1 captures and whose negative, boundary and corner rows are built by hand; a `BenchmarkParse<Kind>` row in `parseBenchCases`.
+6. **goip args** (KG): a `kindData` case and a `parse<Kind>Args` file, following `internal/goip/link_bond_args.go`.
+7. **Render** (KG): `<kind>Data` in `internal/goip/render`, a case in `kindData` or `slaveKindData` (`render/link_detail.go:161`, `:172`), and the kind in `renderableInfoData`.
+8. **goip tests** (KG): replay rows in `TestLinkWriteMatchesIpBytes`, and a `-d` sidecar test following `TestLinkShowDetailBondMatchesSidecar`.
+9. **Matrix** (KG): read rows (`-d link show dev X`, `-d -j …`) and the write rows, gated after two consecutive clean `goip-parity` runs of the row's section (`--section link`).
+
+## Gates every task inherits
+
+These are [goip-parity-gaps.md's gates](goip-parity-gaps.md#gates-every-task-inherits), unchanged:
+- **Unit tests:** `go test -count=1` over the packages the task touches (not `./...`, which fails at link), `-race` for goip and goipparity, and `go vet`.
+- **Mutation checks** in a scratch worktree. Each mutant's `go test` runs in `systemd-run --scope -p MemoryMax=6G -p MemorySwapMax=0` with `-timeout=180s`.
+- **Nix checks, one per call:** lint-baseline, netlink-audit, vm-lib-exp, nix-fmt, statix and deadnix.
+- **VMs, one at a time,** after checking that ports 12055 and 12056 are free:
+  - the capture runners for KC tasks;
+  - `nix run .#microvm-x86_64-goip-parity -- --timeout 12000 --section link` for KG tasks: two consecutive clean runs of the row's section before a row is gated, one regression run otherwise. The section run captures only those rows (`link`'s 48 of 518 in a few minutes, against about 45 for the table).
+  - One clean full run, without `--section`, before any push or PR, since goip's code is shared across sections.
+- **Docs:** the task's checklist row and its `V###` rows land in the task's commit.
+
+## Phases and tasks
+
+The tiers run in this order:
+1. Captures (KC).
+2. Parsers, table tests and benchmarks (KP).
+3. goip and the matrix (KG).
+
+The groups are K0 (the `inet` write) and K1 to K5 ([The kind inventory](#the-kind-inventory)). Each group has one phase per tier: KC*n*+1, KP*n* and KG*n* for group K*n*.
+
+```text
+KC0 ──┬──> KC1 ──> KP0 ──> KG0
+      ├──> KC2 ──> KP1 ──> KG1
+      ├──> KC3 ──> KP2 ──> KG2
+      ├──> KC4 ──> KP3 ──> KG3
+      ├──> KC5 ──> KP4 ──> KG4
+      └──> KC6 ──> KP5 ──> KG5
+KC1 … KC6 ──> KC7
+```
+
+A KP phase needs only its own group's captures, so the groups can move at different speeds. The order is still captures first: KC1 to KC7 close before KP1 starts.
+
+Every task's tests are tables: description | input | expected, with positive, negative, boundary and corner rows. KC0-T01 is planned in full below. Every other phase is broken into tasks, each with its tables, when the phase before it closes.
+
+### Closing a phase
+
+As in [goip-parity-gaps.md](goip-parity-gaps.md#closing-a-phase). In the commit of a phase's last task:
+1. **Status:** every task in the phase is `done` with its `V###` IDs, the phase is `done` in **Phase states**, and **Last updated**, the summary and **Next action** are updated.
+2. **Inventory:** the [kind inventory](#the-kind-inventory) and [Where goip stands](#where-goip-stands) are updated for what the phase landed, and a `DOC###` ledger row names the commit.
+3. **Expand the next phase:** its checklist range row becomes one row per task, each with its test tables here. IDs already listed never change.
+4. **Decisions:** every exclusion, divergence or scope change goes in the decision log.
+5. **Cross-docs:** any statement in [coverage-status.md](coverage-status.md), the README counts or elsewhere in `docs/netlink/` that the phase made false is amended.
+6. **Checks:** task IDs are one to one between this document and the checklist, the graph is acyclic, links and anchors resolve, and spelling is US.
+
+### KC0 — Kind harness
+
+#### KC0-T01 Late kind modules, no fallback tunnels, and a kind probe
+
+**Late modules.** `nltopo::late_modules` (`nix/microvms/scripts/netlink-topology.exp`) gains the kind modules: 8021q, macvlan, macvtap, ipvlan, ipvtap, vxlan, geneve, bareudp, amt, gtp, ip_gre, ip6_gre, ipip, sit, ip6_tunnel, ip_vti, ip6_vti, xfrm_interface, hsr, ifb, vcan, vxcan, batman_adv and team. bridge, nlmon, veth, dummy and bonding are already loaded where they are needed. `late_setup` runs after every existing row in both capture drivers, so the late load moves no committed ifindex (the C0-T02 mechanism).
+- The names are module names, so `batman_adv`, not `batman-adv`: `xtcp2-nlcap modules` refuses a name with a hyphen.
+- Loading the modules here, rather than letting the first `ip link add` load them through `rtnl-link-<kind>`, keeps the load at one known point.
+
+**No fallback tunnels.** `late_setup` sets `net.core.fb_tunnels_only_for_init_net=2`, through the existing `sysctl` subcommand, before its `modules` call.
+- **Why:** ipip, ip_gre, sit, ip6_tunnel and ip6_gre create a fallback device (`tunl0`, `gre0`, `gretap0`, `erspan0`, `sit0`, `ip6tnl0`, `ip6gre0`) in every namespace, including each one created afterwards. The link-write driver rebuilds its namespace for every genl and XFRM row after `late_setup`, so without the sysctl every one of those namespaces would grow seven devices, and every genl and XFRM fixture's ifindexes would move. `mkVm.nix:4034-4050` records the same hazard at boot.
+- **Why value 2 works late:** the kernel checks the sysctl when a namespace is created (`net_has_fallback_tunnels`, `include/linux/netdevice.h:741`). At 2 no namespace gets the devices, init_net included.
+- **The dump driver's tunnel set is unchanged.** It loads ipip, ip_gre, sit, ip6_tunnel and ip6_gre itself before `late_setup`, because the fallback devices are half that set's coverage, and its reads namespace needs them for `ip tunnel show`. Those namespaces exist before the sysctl is set, and the dump driver captures nothing after `late_setup`.
+
+**A kind probe.** A new `xtcp2-nlcap kinds <subdir> <kind>…` subcommand (`nix/microvms/netlink-capture.nix`). For each kind, in argument order, it:
+- makes a scratch namespace holding three dummies, `kl`, `ka` and `kb`, as lower devices;
+- runs `ip link add` for `k0` with the fewest options the kernel accepts (`kind_args`): `kl` as the lower for vlan, macvlan, macvtap, ipvlan, ipvtap and amt; `ka` and `kb` as hsr's slaves; a nonzero `remote` for the tunnels (`ipgre_tap_validate` refuses a zero one); `seq key 1 erspan_ver 1` for the ERSPAN kinds (`erspan_validate`); a table for vrf; a remote for geneve; a port and an ethertype for bareudp. vxcan and netkit name their own peer;
+- runs `ip link del k0`, then deletes the namespace;
+- appends `<kind> ok` or `<kind> refused <ip's stderr>` to `<subdir>/kinds`.
+
+It is never fatal: a refused kind is evidence, not a failure. `late_setup` calls it once, with every K1 to K5 kind, so the `kinds` sidecar records what the guest kernel can create, netkit and gtp included.
+
+**Tests.** The sandbox rows are ccheck rows in `nix/microvms/scripts/addr-topology-test.exp`, run by `checks.vm-lib-exp`. `ip link add` can't succeed in the build sandbox, so they test the argument handling and the sidecar format, and the VM rows test the rest.
+
+| description | input | expected |
+|---|---|---|
+| negative: no kind named | `xtcp2-nlcap kinds k1` | rc 2, `NLCAP_ERR usage: kinds` |
+| negative: no arguments at all | `xtcp2-nlcap kinds` | rc 2, `NLCAP_ERR usage: kinds` |
+| negative: a name that is no kind name | `xtcp2-nlcap kinds k2 dummy Bad-Kind` | rc 2, `NLCAP_ERR kinds: bad kind name: Bad-Kind`, before any probe; no sidecar |
+| boundary: one kind, refused in the sandbox | `xtcp2-nlcap kinds k3 xtcp2nosuchkind` | rc 0, `NLCAP_KINDS_OK k3/kinds n=1`; the sidecar is exactly one line, `xtcp2nosuchkind refused …` |
+| corner: a refused kind doesn't stop the next | `xtcp2-nlcap kinds k4 xtcp2nosuchkind dummy` | rc 0; two sidecar lines, in argument order |
+| positive: `late_setup` sets the sysctl before it loads a module | the recorder's trace | `sysctl - late net.core.fb_tunnels_only_for_init_net 2` comes before `modules late …` |
+| negative: a refused fallback sysctl | the recorder refusing it | the first problem is `sysctl net.core.fb_tunnels_only_for_init_net=2: REFUSED` |
+| positive: a fresh namespace holding `lo` and `nlmon0` | the read answered with those two | no `fallback:` problem, and the `no fallback devices in a new namespace` note |
+| negative: a fallback device in the fresh namespace | the read answered with `gre0@NONE` as well | `fallback: a new namespace holds {lo nlmon0 gre0}, not {lo nlmon0}`, and no note |
+| corner: the fresh namespace is deleted after it is read | the recorder's trace | the read comes before `ns-del nlcapfb` |
+| boundary: `link_names` drops the `@<lower>` suffix | `3: gre0@NONE: …` and `4: erspan0@NONE: …` | `gre0 erspan0` |
+| corner: an empty read, as when the namespace wasn't made | `""` | a `fallback:` problem naming `{}` |
+| boundary: `lo` alone | `{lo}` | a problem, since `ns-add` makes `nlmon0` |
+| positive: `late_setup` probes every in-scope kind | the recorder's calls | one `kinds late …` call naming the 32 creatable kinds; no slave kind |
+| corner: the module list | `nltopo::late_modules` | ip_gre, ip6_tunnel and batman_adv present, every kind module after every genl and XFRM module, no name with a dash |
+
+The fresh namespace is made with `xtcp2-nlcap ns-add`, which adds the `nlmon0` capture device, so `lo nlmon0` is what every row's namespace starts with. The existing "corner: late_setup loads the l2tp, macsec and xfrm modules and no tunnel module" row asserted the opposite of the last row, and is replaced by it.
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: every in-scope kind is created | `late/kinds` from both drivers | every kind `ok`, or `refused` with a decision-log entry |
+| positive: no fallback devices in a namespace made after `late_setup` | `late/topology` | the `no fallback devices in a new namespace` note, and no `NLCAP_LATE_FAILED` |
+| corner: the fixtures captured before `late_setup` don't move | every pcap, against the committed corpus, by record count, protocol, `(type, len)` sequence and masked bytes (V005's and V013's method) | the same as `main`'s run of the same comparison |
+
+**Mutation check** (scratch worktree, through `vm-lib-exp`; each mutant must be killed by a named row):
+- the sysctl call dropped;
+- the sysctl moved after the `modules` call;
+- a refused kind made fatal (rc 1);
+- the sidecar written in reverse order.
+
+**Done when:** the table rows pass in `vm-lib-exp`; lint-baseline, nix-fmt, statix and deadnix pass; `microvm-x86_64-link-write-capture` and `microvm-x86_64-netlink-dump-capture` each print `NLCAP_DRIVER_PASS`, with the VM rows above checked against their blobs.
+
+### KC1 — `inet` devconf captures
+
+One task. Its rows are the source KP0's decoder and KG0's parser are tested against: every request shape `iplink_parse_inet` builds, the kernel's range checks on them, and every way `ip` refuses the words before it sends anything.
+
+#### KC1-T01 `inet` devconf write rows
+
+**Rows.** A block appended to `rtnlcorpus::rows` (`nix/microvms/scripts/rtnl-write-corpus.exp`), after C1-T04's rows, so it runs after every existing rtnl row and before `late_setup`. Every row's pre is `PRE_D0`, so the device is d0 at ifindex 3.
+- **Readbacks,** on every row the kernel answers: `{getnetconf 4 {ip netconf show dev d0}}` and `{getlink_detail 2 {ip -d link show dev d0}}`. `ip netconf` prints only forwarding, rp_filter, mc_forwarding, proxy_neigh and ignore_routes_with_linkdown, but the `RTM_NEWLINK` answer to the second carries the whole `IFLA_INET_CONF` array, so every param's value is in a pcap.
+- **The write's floor** is 4: d0's name lookup and the `RTM_NEWLINK` with its ACK or refusal.
+- **A row `ip` refuses before netlink** has floor 0 and no readbacks. Its status is 255 when `ip` calls `exit(-1)` (`invarg`, `incomplete_command`, `duparg2`), and 1 when the parse error is returned instead: `do_cmd` (`ip/ip.c:131`) exits with the negated return, and a failed `parse_on_off` returns -1 up the stack. The first VM run found the 1; the plan had assumed 255. Its `ip.err` is the evidence: KG0 matches those texts and statuses. `rc_values` and `bad_floors` in the hermetic check learn this third kind of row.
+
+| slug | command (`ip link set dev d0 …`) | rc | what it pins |
+|---|---|---|---|
+| `inet_forwarding_on` | `inet forwarding on` | 0 | one on/off param |
+| `inet_rp_filter_max` | `inet rp_filter 2` | 0 | a numeric param at the top of the kernel's range |
+| `inet_rp_filter_over` | `inet rp_filter 3` | 2 | `inet_devconf_policy`'s range, one past it (`EINVAL`) |
+| `inet_tag_hex` | `inet tag 0x10` | 0 | base 0: hex |
+| `inet_arp_ignore_octal` | `inet arp_ignore 010` | 0 | base 0: a leading 0 is octal, so 8, the top of `ARP_IGNORE`'s range |
+| `inet_medium_id_neg1` | `inet medium_id -1` | 0 | the one signed param (`NLA_POLICY_MIN(NLA_S32, -1)`), sent as `0xffffffff` |
+| `inet_medium_id_neg2` | `inet medium_id -2` | 2 | one under its minimum |
+| `inet_several` | `inet forwarding on proxy_arp on rp_filter 1 arp_ignore 2` | 0 | several params in one nest, in argument order |
+| `inet_every_param` | all 32 params, on/off ones `on`, numeric ones in range | 0 | every keyword and its devconf id |
+| `inet_repeated` | `inet forwarding on forwarding off` | 0 | both attributes sent; the kernel applies the last |
+| `inet_then_mtu` | `inet forwarding on mtu 1400` | 0 | the push-back: `mtu` returns to `iplink_parse`, and one request carries `IFLA_MTU` and `IFLA_AF_SPEC` |
+| `inet_then_garbage` | `inet forwarding on bogus` | 255 | the pushed-back word reaches `iplink_parse` as a second device name (`duparg2`) |
+| `inet_bad_on_off` | `inet forwarding maybe` | 1 | `parse_on_off`'s error, returned rather than exited on |
+| `inet_bad_number` | `inet rp_filter x` | 255 | `Invalid "rp_filter" value` |
+| `inet_no_param` | `inet` | 255 | `incomplete_command`: nothing after `inet` |
+| `inet_unknown_param` | `inet bogus on` | 255 | `incomplete_command`: the first word is no param |
+| `inet_abbreviated` | `inet forw on` | 255 | `strcmp`, not `matches`: no abbreviation |
+| `inet_no_value` | `inet forwarding` | 255 | `incomplete_command` from `NEXT_ARG` |
+
+**Tests.** Hermetic rows in `nix/microvms/scripts/rtnl-write-corpus-test.exp`, run by `checks.vm-lib-exp`:
+
+| description | input | expected |
+|---|---|---|

+| positive: the accepted rows reach the device | `getlink_detail` of `inet_every_param` | each of the 32 devconf ids holds the value sent |
+| corner: the last of a repeated param wins | `getnetconf` of `inet_repeated` | `forwarding off` |
+| corner: a refused row changes nothing | `getlink_detail` of `inet_rp_filter_over` | rp_filter as before the row (the namespace default) |
+| negative: `ip` refuses without a datagram | the 7 `ip`-refused rows' `ip.pcap` | no datagram; `ip.err` holds the text named in the table |
+| corner: the rows before move nothing | every other pcap against V004's run, as V004 compares | the same shape apart from the reorderings V004 lists |
+
+**Mutation check** (scratch worktree, through `vm-lib-exp`; each mutant killed by a named row):
+- `bad_rc` back to `{0 2}`;
+- the `ip`-refused exemption in `bad_floors` dropped;
+- `inet_rp_filter_over` given rc 0;
+- two `inet` rows swapped.
+
+**Done when:** the hermetic rows pass in `vm-lib-exp`; nix-fmt, statix and deadnix pass; `microvm-x86_64-link-write-capture` captures the 18 rows with the statuses above, and its only failure is `genl/mptcp_limits_set_over` (see the [decision log](goip-link-kinds-status.md#decision-log)); the VM rows hold.
+
+### KC2 — Bridge captures
+
+bridge and bridge_slave, with 7.2.0's `stp_mode` and `neigh_forward_grat`. Two tasks: KC2-T01 builds the kind corpus every later KC phase adds rows to, with bridge as its first kind; KC2-T02 adds bridge_slave.
+
+**Keyword matching differs inside one file.** `iplink_bridge.c` matches most of its 41 keywords with `matches` (so `forward_d` is `forward_delay`) and a few with `strcmp` (`stp_mode`, `mst_enabled`, `mdb_offload_fail_notification`, `fdb_local_vlan_0` among them). KP1's option table records which, and KC2-T01 has a row for each kind of match.
+
+#### KC2-T01 The kind corpus, and bridge
+
+**The corpus.** A new `nix/microvms/scripts/kind-write-corpus.exp`, data plus small procs like `rtnl-write-corpus.exp`, sourced by `capture-link-writes.exp`. Its rows run **after `late_setup`**, as the genl rows do, because the kind modules load there.
+- **A row** is `{slug floor pre command readbacks rc}`, `rtnlcorpus`'s shape, captured into `link-write/kinds/<kind>/<slug>/` by a `kind_row` proc in the driver (`rtnl_row`'s body, with the subdir).
+- **Readbacks**, on every row the kernel answers: `{getlink_detail 2 {ip -d link show dev <dev>}}`, `{getlink_detail_json 2 {ip -d -j -p link show dev <dev>}}` and `{getlink 2 {ip link show dev <dev>}}`.
+- **Statuses** are KC1-T01's: 0, 2, or 1 or 255 for a row `ip` refuses before netlink (floor 0, no readback).
+- **The hermetic check** is a new `nix/microvms/scripts/kind-write-corpus-test.exp`, added to `checks.vm-lib-exp`.
+
+**Bridge rows**, under `kinds/bridge/`. The device is `br0`. A row's expected status is the kernel's answer as argued from `br_changelink` and `br_policy` (`net/bridge/br_netlink.c`); the first VM run confirms each one, and any it contradicts is corrected in the plan with the reason, as KC1-T01's rc 1 was.
+
+| slugs | command | rc | what it pins |
+|---|---|---|---|
+| `add_default` | `ip link add br0 type bridge` | 0 | no `INFO_DATA` sent; the readback is every attribute's default |
+| `add_<option>`, one per value-taking option but `stp_mode` (39) | `ip link add br0 type bridge <option> <value>`, a value the kernel accepts and that differs from the default | 0 | each keyword's attribute, width and encoding |
+| `add_fdb_flush` | `… type bridge fdb_flush` | 0 | the one flag with no value (`IFLA_BR_FDB_FLUSH`, empty) |
+| `add_stp_mode_<mode>` | `stp_mode auto`, `user`, `kernel` | 0 | 7.2.0's `IFLA_BR_STP_MODE`, each name |
+| `add_boolopts` | `mst_enabled 1 mdb_offload_fail_notification 1 fdb_local_vlan_0 1` | 0 | the three boolopts folded into one `IFLA_BR_MULTI_BOOLOPT` |
+| `add_several` | `stp_state 1 priority 100 vlan_filtering 1 mcast_snooping 0` | 0 | several attributes in one request, in argument order |
+| `set_<option>` for `ageing_time`, `vlan_filtering`, `stp_mode` | `ip link set br0 type bridge <option> <value>` on an existing `br0` | 0 | the change path (`br_changelink`), with no `IFLA_INFO_KIND` change |
+| `add_abbrev` | `forward_d 400` | 0 | a `matches` keyword taking an abbreviation |
+| `add_stp_mode_abbrev` | `stp_m user` | 1 | a `strcmp` keyword refusing one: `bridge_parse_opt` returns "unknown command" |
+| `add_group_address_bad` | `group_address 01:80:c2:00:00:01` | 2 | `br_changelink`: not a usable link-local group |
+| `add_group_fwd_mask_bad` | `group_fwd_mask 1` | 2 | a restricted bit |
+| `add_igmp_version_bad` | `mcast_igmp_version 4` | 2 | outside 2 to 3 |
+| `add_mcast_vlan_snooping_no_vlan` | `mcast_vlan_snooping 1` | 2 | needs `vlan_filtering` (so `add_mcast_vlan_snooping` sends `vlan_filtering 1` first) |
+| `set_stp_mode_busy` | `ip link set br0 type bridge stp_mode user` on a `br0` with STP on | 2 | `EBUSY`: the mode can't change while STP runs |
+| `add_stp_mode_bad` | `stp_mode bogus` | 1 | `parse_one_of`'s error, returned |
+| `add_vlan_protocol_bad` | `vlan_protocol 802.1x` | 255 | `ll_proto_a2n` |
+| `add_priority_bad` | `priority x` | 255 | `get_u16` |
+| `add_no_value` | `forward_delay` | 255 | `NEXT_ARG` |
+
+**Tests.** Hermetic rows in `kind-write-corpus-test.exp`:
+
+| description | input | expected |
+|---|---|---|
+| positive: the rows are the plan's, in run order | `slugs $R` | the table's slugs, `add_default` first |
+| positive: one `add_` row per value-taking option | the bridge option keywords in the rows | the 39 keywords `iplink_bridge.c` parses with a value, `stp_mode` aside, each once |
+| negative: every row is `{slug floor pre command readbacks rc}` | a five-field row | listed |
+| negative: no slug names two rows | a duplicated slug | listed |
+| boundary: every status is 0, 1, 2 or 255 | `bad_rc` | `{}`; a row at 3 is listed |
+| boundary: an `ip`-refused row's floor is 0 and it has no readback | `bad_floors` | `{}`; one with floor 2 or a readback is listed |
+| boundary: a kernel-answered row's floor is 2 for an add, 4 for a set (the name lookup) | `bad_floors` | `{}`; a set at 2 is listed |
+| positive: every kernel-answered row reads back three ways | `readback_names` | `getlink_detail getlink_detail_json getlink` |
+| corner: no command holds a single quote | `quoted` | `{}` |
+| corner: every `set_` row's pre makes `br0` | `field <slug> 2` | `{link add br0 type bridge}` |
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: each row's status | `kinds/bridge/*/ip.rc` | the table's rc |
+| positive: each `add_<option>` reaches the device | `getlink_detail_json` | the option's value, as `ip -d -j` prints it: under its attribute's name (`group_addr`, `…_cnt`, `…_intvl`), `group_fwd_mask` in hex, and `mcast_hash_elasticity` at 16 whatever is sent |
+| corner: a refused add leaves no device | the row's `getlink` readback | empty text, and the pcap's answer is `NLMSG_ERROR` `-ENODEV` |
+| corner: the corpus runs after every existing row | every other pcap, against KC1-T01's run | no new shape difference |
+
+**Mutation check:** `bad_rc` narrowed, the `ip`-refused floor exemption dropped, an `add_` row dropped (the per-option row), two rows swapped.
+
+**Done when:** `vm-lib-exp`, nix-fmt, statix and deadnix pass; `microvm-x86_64-link-write-capture` captures every row with its status, and its only failure is `genl/mptcp_limits_set_over`.
+
+#### KC2-T02 bridge_slave
+
+Rows under `kinds/bridge_slave/`, in `kind-write-corpus.exp`, after bridge's. The pre is `br0` with dummies `p0` and `p1` enslaved; the command is `ip link set dev p0 type bridge_slave …`, floor 4, and each readback reads `p0`.
+
+| slugs | command | rc | what it pins |
+|---|---|---|---|
+| `set_<option>`, one per value-taking option but `neigh_forward_grat` and `backup_port`, which have rows of their own (24), each with a value off the port's default | `type bridge_slave <option> <value>` | 0 | each keyword's `IFLA_BRPORT_*`. `set_state`'s pre brings `p0` up (with `addrgenmode none`), as `br_set_port_state` refuses a down port; `set_mab` sets `locked on` first |
+| `set_fdb_flush`, `set_nobackup_port` | the two flags with no value | 0 | empty `IFLA_BRPORT_FLUSH`, and `IFLA_BRPORT_BACKUP_PORT` 0 (its pre sets `backup_port p1`, so it is a change) |
+| `set_neigh_forward_grat` | `neigh_forward_grat on` | 0 | 7.2.0's option |
+| `set_backup_port` | `backup_port p1` | 0 | an ifindex the readback prints as a name (the `ll_index_to_name` hazard) |
+| `set_several` | `cost 10 priority 7 learning off` | 0 | several attributes in one request |
+| `set_abbrev` | `co 10` | 0 | `matches` takes an abbreviation |
+| `set_strcmp_abbrev` | `neigh_forward_g on` | 1 | a `strcmp` keyword's abbreviation is an unknown word, which returns |
+| `set_state_bad` | `state 5` | 2 | past `BR_STATE_BLOCKING` |
+| `set_priority_over` | `priority 64` | 2 | one past `BR_MAX_PORT_PRIORITY` (63) |
+| `set_cost_zero` | `cost 0` | 2 | one under `BR_MIN_PATH_COST` |
+| `set_group_fwd_mask_bad` | `group_fwd_mask 2` | 2 | `BR_GROUPFWD_MACPAUSE` |
+| `set_mab_unlocked` | `mab on` | 2 | MAB on an unlocked port |
+| `set_backup_port_self` | `backup_port p0` | 2 | a port can't back itself up |
+| `set_not_enslaved` | `cost 10`, on a dummy with no master | 2 | the kernel's refusal of slave data on a non-port (`-EOPNOTSUPP`) |
+| `set_backup_port_missing` | `backup_port nosuch` | 255 | `ip`'s name lookup, then `invarg`; the lookup is on the wire, so the row has datagrams despite its floor of 0 |
+| `set_cost_bad` | `cost x` | 255 | `get_u32` |
+| `set_on_off_bad` | `learning maybe` | 1 | `bridge_slave_parse_on_off`'s `exit(1)` |
+| `set_no_value` | `cost` | 255 | `incomplete_command` |
+
+Its tests are KC2-T01's tables over the 102 rows, plus:
+
+| description | input | expected |
+|---|---|---|
+| positive: one `set_` row per value-taking option, then `neigh_forward_grat`'s and `backup_port`'s | the `set_<option>` rows | the 24 keywords in `iplink_bridge_slave.c`'s order, then the two |
+| boundary: bridge's rows come first | the slug list | the first `bridge_slave/` row is the 61st |
+| positive: a port row's pre and readbacks | `set_cost` | br0 with p0 and p1 enslaved; three reads of `p0` |
+| corner: `state` brings the port up; its refusal doesn't need to | `set_state`, `set_state_bad` | `addrgenmode none` and `up` last; the bare pre |
+| corner: `mab` locks first; alone, it is refused | `set_mab`, `set_mab_unlocked` | `locked on mab on` at 0; `mab on` at 2 |
+| boundary: the kernel's priority and cost ranges | `set_priority_over`, `set_cost_zero` | 64 and 0, each at 2 |
+| corner: a bad on/off exits 1, a missing value 255 | `set_on_off_bad`, `set_no_value` | 1, 255 |
+| negative: the non-port | `set_not_enslaved` | a lone dummy `p0`, at 2 |
+| positive (VM): the values read back | each row's `-d -j` readback | the value sent; `backup_port` as `p1` |
+
+**Mutation check:** `mab` dropped from the option list, `mab`'s row without `locked on`, `state`'s row without `p0` up, `set_on_off_bad` at 255, `set_not_enslaved` on an enslaved `p0`.
+
+**Done when:** as KC2-T01. It closes KC2.
+
+### KC3 — VLAN family captures
+
+vlan, macvlan, macvtap, ipvlan and ipvtap: kinds stacked on a lower device. Three tasks, one per parser file: KC3-T01 vlan, KC3-T02 macvlan and macvtap (one parser, two kinds), KC3-T03 ipvlan and ipvtap (likewise), which closes KC3.
+
+**Shared shape.** Rows go in `kind-write-corpus.exp` after bridge_slave's, under `kinds/<kind>/`. Every row's pre makes a dummy `d0`, the lower device; an add is `ip link add link d0 name <dev> type <kind> …`, a set `ip link set <dev> type <kind> …` on a device the pre made. Floors, readbacks and statuses are KC2's. Each kind's kernel checks are argued from its `validate`, `newlink` and `changelink` (`net/8021q/vlan_netlink.c`, `drivers/net/macvlan.c`, `drivers/net/ipvlan/ipvlan_main.c`), and the first VM run confirms them.
+
+**`ip` refusals in these files return,** so they exit 1, except where a value goes through `invarg` or `NEXT_ARG`, which exit 255: vlan's `on_off`, macvlan's `mode_arg`, `flag_arg`, `bc_queue_len_arg` and `bclim_arg`, and ipvlan's mode error all return -1.
+
+#### KC3-T01 vlan
+
+The device is `v0`; `id` is required, so every add but `add_no_id` sends one.
+
+| slugs | command (after `type vlan`) | rc | what it pins |
+|---|---|---|---|
+| `add_default` | `id 10` | 0 | `IFLA_VLAN_ID` alone; `reorder_hdr` reads back on, the kernel's default |
+| `add_protocol` | `id 10 protocol 802.1ad` | 0 | `IFLA_VLAN_PROTOCOL`, big-endian |
+| `add_<flag>` for `reorder_hdr off`, `gvrp on`, `mvrp on`, `loose_binding on`, `bridge_binding on` (5) | `id 10 <flag> <value>` | 0 | `IFLA_VLAN_FLAGS`'s `{flags, mask}` pair, one bit each |
+| `add_ingress_qos_map`, `add_egress_qos_map` | `id 10 ingress-qos-map 1:2 3:4`, `id 10 egress-qos-map 2:1 4:3` | 0 | the nested `IFLA_VLAN_QOS_MAPPING` lists |
+| `add_several` | `id 10 protocol 802.1ad gvrp on mvrp on` | 0 | one flags attribute for two flags |
+| `add_id_max` | `id 4094` | 0 | the highest id |
+| `add_abbrev` | `i 10` | 0 | `matches` |
+| `set_flags` | `loose_binding on`, on `v0` | 0 | the change path |
+| `set_egress_qos_map` | `egress-qos-map 1:5`, on `v0` | 0 | a mapping added by a change |
+| `set_id` | `id 20`, on `v0` (id 10) | 0 | `vlan_changelink` ignores the id: the readback still says 10 |
+| `add_no_id` | (no option) | 2 | "VLAN properties not specified" |
+| `add_no_link` | `ip link add name v0 type vlan id 10` | 2 | "link not specified" |
+| `add_id_over` | `id 4095` | 2 | `id >= VLAN_VID_MASK` |
+| `add_protocol_unsupported` | `id 10 protocol ip` | 2 | a protocol `ip` knows and the kernel refuses (`-EPROTONOSUPPORT`) |
+| `add_duplicate_id` | `v1`, `id 10`, on a `d0` that `v0` already uses with id 10 | 2 | `-EEXIST` |
+| `add_on_loopback` | `link lo` | 2 | `lo` is VLAN-challenged |
+| `add_on_off_bad` | `id 10 gvrp maybe` | 1 | vlan's `on_off`, returned |
+| `add_unknown` | `id 10 bogus` | 1 | "unknown command" |
+| `add_qos_no_colon` | `id 10 egress-qos-map 5` | 1 | `parse_mapping` stops at a word with no colon, which is then an unknown command |
+| `add_id_bad` | `id x` | 255 | `get_u16` |
+| `add_protocol_bad` | `protocol 802.1x` | 255 | `ll_proto_a2n` |
+| `add_qos_bad` | `id 10 ingress-qos-map 1:x` | 255 | `invarg` after `parse_qos_mapping` |
+| `add_no_value` | `id` | 255 | `NEXT_ARG` |
+
+**Tests**, in `kind-write-corpus-test.exp`, over the vlan rows:
+
+| description | input | expected |
+|---|---|---|
+| positive: the rows are the plan's, after bridge_slave's | the slug list | the table's slugs, in order |
+| positive: one `add_<flag>` row per flag keyword | the vlan flag rows | `reorder_hdr gvrp mvrp loose_binding bridge_binding`, each once |
+| negative: exactly the refusal rows expect a non-zero status | `refused_rows` | the table's 2s, 1s and 255s |
+| boundary: the id range | `add_id_max`, `add_id_over` | 4094 at 0, 4095 at 2 |
+| corner: `set_id` sends a new id on an existing `v0` | its pre and command | `v0` made with `id 10`; `id 20` |
+| corner: the duplicate's pre holds `v0` | `add_duplicate_id`'s pre and readback device | `v0` with id 10; the readbacks read `v1` |
+| negative: the no-link row names no lower | `add_no_link`'s command | no `link` word |
+| positive: every vlan row's pre makes `d0` | the pres | `{link add d0 type dummy}` first |
+| positive (VM): each status, and the values read back | `ip.rc`; `-d -j` readbacks | the table's rc; `id`, `protocol`, the flags and the maps as sent, `set_id`'s id 10 |
+
+**Mutation check:** a flag row dropped, `add_id_over` at 4094, `set_id`'s pre without `v0`, `add_qos_no_colon` at 255.
+
+**Done when:** as KC2-T01.
+
+#### KC3-T02 macvlan and macvtap
+
+The device is `m0`. macvlan gets the full set; macvtap, which shares `macvlan_parse_opt`, gets the rows that show it is the same parser on another kind.
+
+| slugs | command (after `type macvlan`) | rc | what it pins |
+|---|---|---|---|
+| `add_default` | (no option) | 0 | no `INFO_DATA`; the mode reads back `vepa` |

+| `add_flag_nodst`, `add_nodst`, `add_flag_null` | `mode bridge flag nodst`, `mode bridge nodst`, `mode bridge flag null` | 0 | `IFLA_MACVLAN_FLAGS` both ways, and a flags attribute of 0 |
+| `add_passthru_nopromisc` | `mode passthru nopromisc` | 0 | the flag passthru alone takes |

+| `set_bcqueuelen` | `bcqueuelen 500`, on `m0` | 0 | a shared port setting changed |
+| `set_passthru` | `mode passthru`, on a bridge-mode `m0` | 2 | passthru can't be set dynamically |
+| `add_macaddr_not_source` | `mode bridge macaddr add 02:00:00:00:00:01` | 2 | source addresses need source mode |
+| `add_macaddr_multicast` | `mode source macaddr add 01:00:5e:00:00:01` | 2 | `-EADDRNOTAVAIL` |
+| `add_second_passthru` | `m1`, `mode passthru`, on a `d0` that a passthru `m0` holds | 2 | one passthru per lower |

+macvtap, under `kinds/macvtap/` with the device `t0`: `add_default`, `add_mode_bridge`, `add_mode_passthru`, `add_bcqueuelen` and `set_mode` at 0, `add_mode_bad` at 1.
+
+**Tests:**
+
+| description | input | expected |
+|---|---|---|
+| positive: the rows are the plan's, after vlan's | the slug list | the two tables' slugs, macvlan's then macvtap's |
+| positive: one `add_mode_` row per mode | the mode rows | the five, each once |
+| negative: exactly the refusal rows expect a non-zero status | `refused_rows` | the table's |
+| corner: the source rows' pres | `set_macaddr_del`'s pre | `m0` in source mode holding the address deleted |
+| corner: the second passthru's pre | `add_second_passthru`'s pre | a passthru `m0`; the readbacks read `m1` |

+| corner: macvtap rows say `type macvtap` | every `kinds/macvtap/` command | `type macvtap`, the device `t0` |
+| positive (VM): each status, and the values read back | `ip.rc`; `-d -j` readbacks | the table's rc; mode, flags, `bcqueuelen`, `bclim` and the source list as sent |
+
+**Mutation check:** a mode row dropped, `add_bclim_abbrev` at 0, `set_macaddr_del`'s pre without the address, a macvtap row's kind made macvlan.
+
+**Done when:** as KC2-T01.
+
+#### KC3-T03 ipvlan and ipvtap
+
+The device is `i0`. Once any option follows `type ipvlan`, `ip` sends `IFLA_IPVLAN_FLAGS`, 0 when no flag word is given, so a `set` of the mode alone clears the flags too. With no option at all, `iplink_parse` doesn't call `parse_opt`, and no `INFO_DATA` is sent.
+
+| slugs | command (after `type ipvlan`) | rc | what it pins |
+|---|---|---|---|
+| `add_default` | (no option) | 0 | no `INFO_DATA`; the mode reads back `l3` |
+| `add_mode_<mode>` for `l2`, `l3`, `l3s` (3) | `mode <mode>` | 0 | `IFLA_IPVLAN_MODE`'s values |
+| `add_<flag>` for `private`, `vepa`, `bridge` (3) | `<flag>` | 0 | the flag bits, `bridge` as 0 |
+| `add_mode_and_flag` | `mode l2 vepa` | 0 | both attributes |
+| `add_abbrev` | `mo l2` | 0 | `matches` |
+| `set_mode` | `mode l2`, on an `i0` made `private` | 0 | the change path; the readback shows `private` cleared |
+| `set_flag` | `vepa`, on `i0` | 0 | a flag changed |
+| `add_no_link` | `ip link add name i0 type ipvlan` | 2 | no lower |
+| `add_on_loopback` | `link lo` | 2 | not an Ethernet lower |

+
+### KC4 — UDP overlay captures
+
+vxlan, geneve (with 7.2.0's `local`), bareudp, amt and gtp: kinds with no lower device of their own, each a UDP socket in the namespace. Four tasks: KC4-T01 vxlan, KC4-T02 geneve, KC4-T03 bareudp and amt, KC4-T04 gtp, which closes KC4.
+
+**Shared shape.** Rows go in `kind-write-corpus.exp` after ipvtap's, under `kinds/<kind>/`. An add is `ip link add <dev> type <kind> …` with no lower; a row that names a lower (`dev d0`) has `link add d0 type dummy` in its pre. A set is `ip link set <dev> type <kind> …` on a device the pre made. Floors, readbacks and statuses are KC2's. Each kind's kernel checks are argued from its `validate`, `newlink` and `changelink` (`drivers/net/vxlan/vxlan_core.c`, `drivers/net/geneve.c`, `drivers/net/bareudp.c`, `drivers/net/amt.c`, `drivers/net/gtp.c`), and the first VM run confirms them.
+
+**Statuses these files add to KC3's rule:**
+- **`get_addr` exits 1, not 255.** A bad or wrong-family address calls `exit(1)` (`lib/utils.c`), so it reads like a returned error. `exit(nodev(…))` and `missarg` exit 255.
+- **The kernel validates a set as well as an add.** `rtnl_newlink` calls the kind's `validate` before it splits create from change, so a set with no option (no `INFO_DATA`) is refused like an add with none. A set that passes `validate` on a kind with no `changelink` (bareudp, amt, gtp) is `-EOPNOTSUPP`.
+- **Each kind refuses a bare `type <kind>`.** With no option `parse_opt` isn't called and no `INFO_DATA` is sent; all five `validate`s refuse `!data`. This is why KC0's gtp probe was refused.
+
+#### KC4-T01 vxlan
+
+The device is `vx0`. `ip` requires `id` (or `external`), and warns on stderr when no `dstport` is given; `ip`'s own checks pre-empt the kernel's id range, local multicast, group without `dev`, the family mismatch on add, and `vnifilter` without `external`. Rows but `add_default` send `dstport 4789`, so stderr holds only errors. "base" is `id 42 dstport 4789`.
+
+| slugs | command (after `type vxlan`) | rc | what it pins |

+
+#### KC4-T02 geneve
+
+The device is `gn0`. On an add `ip` requires `id` and `remote` unless `external` is given, and always sends `ID`, `LABEL`, `TTL` and `TOS`; on a set it requires `id` only. 7.2.0's one new keyword is `local` (`strcmp`), which sends `IFLA_GENEVE_LOCAL` or `IFLA_GENEVE_LOCAL6` by the address's family; `local6`, like `remote6`, is an output key, not a keyword. "base" is `id 1 remote 10.0.0.1`.
+
+| slugs | command (after `type geneve`) | rc | what it pins |
+|---|---|---|---|
+| `add_default` | base | 0 | `ID`, `REMOTE`, and the zeros `ip` always sends |

+
+**Done when:** as KC2-T01.
+
+#### KC4-T03 bareudp and amt
+
+Two small kinds, neither with a `changelink`. bareudp (`b0`) needs `dstport` and `ethertype`, which `ip` enforces with `missarg` (255); every keyword is `matches`. amt (`a0`) needs a lower, a mode and a local address, which only the kernel enforces; every keyword is `strcmp`, and only `local` and `discovery` are checked for repeats. amt's rows put `d0` in the pre; "relay" is `mode relay dev d0 local 10.0.0.1`.
+
+| slugs | command | rc | what it pins |

+
+#### KC4-T04 gtp
+
+The device is `g0`. Once any option follows `type gtp`, `ip` sends `IFLA_GTP_CREATE_SOCKETS`, so the kernel opens its own UDP sockets (ports 3386 and 2152, any address) in the namespace; `role` is required (returned, 1), `hsize` defaults to 1024, and an unknown word is skipped silently. There is no `changelink`. KC0's probe was refused because it sent no option (see the shared shape); `role ggsn` is enough.
+
+| slugs | command (after `type gtp`) | rc | what it pins |
+|---|---|---|---|
+| `add_ggsn`, `add_sgsn` | `role ggsn`; `role sgsn` | 0 | `CREATE_SOCKETS`, `ROLE`, `PDP_HASHSIZE` 1024 |

+
+### KC5 — IP tunnel captures
+
+gre, gretap, erspan, ip6gre, ip6gretap, ip6erspan, ipip, sit, ip6tnl, vti, vti6 and xfrm: point-to-point and Ethernet tunnels over IPv4 and IPv6, each optionally bound to a lower with `dev`. Five tasks, one per iproute2 parser or pair: KC5-T01 gre, gretap and erspan (`link_gre.c`); KC5-T02 ip6gre, ip6gretap and ip6erspan (`link_gre6.c`); KC5-T03 ipip and sit (`link_iptnl.c`); KC5-T04 ip6tnl (`link_ip6tnl.c`); KC5-T05 vti, vti6 and xfrm (`link_vti.c`, `link_vti6.c`, `link_xfrm.c`), which closes KC5.
+
+**Shared shape.** Rows go in `kind-write-corpus.exp` after gtp's, under `kinds/<kind>/`, with KC4's shape: an add names no lower unless the row is about `dev d0`, which puts `link add d0 type dummy` in the pre, and a set acts on a device the pre made. The fallback names (`gre0`, `gretap0`, `erspan0`, `ip6gre0`, `tunl0`, `sit0`, `ip6tnl0`, `ip_vti0`, `ip6_vti0`) are never used, and KC0's `fb_tunnels_only_for_init_net=2` keeps every row's namespace free of them. Each kind's kernel checks are argued from its `validate`, `newlink` and `changelink` (`net/ipv4/ip_gre.c`, `net/ipv4/ip_tunnel.c`, `net/ipv6/ip6_gre.c`, `net/ipv4/ipip.c`, `net/ipv6/sit.c`, `net/ipv6/ip6_tunnel.c`, `net/ipv4/ip_vti.c`, `net/ipv6/ip6_vti.c`, `net/xfrm/xfrm_interface_core.c`), and the first VM run confirms them.
+
+**What these files add to KC4's rules:**
+- **A bare `type <kind>` is accepted.** Unlike KC4's kinds, no tunnel `validate` refuses `!data` (xfrm's `newlink` does, for its `if_id`). The device gets the kernel's defaults, which can differ from the ones `ip` sends once any word is given.
+- **A set fetches before it sends.** The gre, gre6, iptnl, ip6tnl, vti and vti6 parsers, on a set (no `NLM_F_CREATE`), first send an `RTM_GETLINK` for the device and prefill every attribute it reports, so a set's request carries the device's current values plus the changed words. A set on a device with no `INFO_DATA` fails in `ip` ("Failed to get existing tunnel info.", 1). xfrm has no prefetch.
+- **A bare set changes nothing.** With no words no `INFO_DATA` is sent, and `rtnl_changelink` calls `changelink` only when it is present, so the set is 0.
+- **No duplicate checks.** These parsers have no `check_duparg`; a repeated word overwrites the earlier one, so there are no `duparg` rows.
+- **fou is loaded, fou6 isn't.** `late_modules` loads `fou` for its genl family, and it registers the IPv4 FOU and GUE encap ops, so gre's, ipip's and sit's `encap fou`/`gue` rows are accepted. Nothing loads `fou6`, so on ip6gre, ip6gretap and ip6tnl `ip6_encap_hlen` finds no ops and the kernel refuses the encap (`-EINVAL`, 2); the request still carries every `ENCAP_*` attribute, which is what the parsers need.
+- **The guest has no `CONFIG_IPV6_SIT_6RD`.** sit's 6rd words are sent and ignored.
+
+#### KC5-T01 gre, gretap and erspan
+
+All three kinds use one parser in `ip/link_gre.c`, `gre_parse_opt`, and one kernel file, `net/ipv4/ip_gre.c`, on top of `net/ipv4/ip_tunnel.c`. The devices are `gr0` (gre), `gt0` (gretap) and `es0` (erspan), with `gr1`/`gt1` as the second device. `gre0`, `gretap0` and `erspan0` are the fallback names, so they are avoided; the harness's `fb_tunnels_only_for_init_net=2` means no row's namespace has a fallback device. `ip` requires no option. Once any word follows `type <kind>`, `ip` sends `IKEY`, `OKEY`, `IFLAGS`, `OFLAGS`, `PMTUDISC` (1 by default), `TOS`, `TTL`, `FWMARK` and the four `ENCAP_*`. It sends `LOCAL`/`REMOTE` only when the address is neither `any` nor 0.0.0.0, `LINK` only for `dev`, and `IGNORE_DF` only when `ignore-df` or `noignore-df` is given. erspan also always sends `ERSPAN_VER` (default 1), plus `ERSPAN_INDEX` when the version is 1 and the index is nonzero, or `ERSPAN_DIR` and `ERSPAN_HWID` when the version is 2. `external` sends `COLLECT_METADATA` **alone** and drops every other word. The parser has no `noexternal`, and the help text's `[no]encap-csum6` is not a keyword (the parser expects `encap-udp6-csum`).
+
+- **Keyword matching.** `matches` (abbreviations accepted, first match wins) covers the key, seq and csum families with their `no`/`i`/`o` forms, `[no]pmtudisc`, `remote`, `local`, `dev`, `ttl`/`hoplimit`/`hlim` and `tos`/`tclass`/`dsfield`. So `no` means `nokey`, `s` means `seq` and `c` means `csum`. `strcmp` covers `noencap`, `encap` and its values, `encap-sport`/`-dport`, `[no]encap-csum`, `[no]encap-udp6-csum`, `[no]encap-remcsum`, `external`, `[no]ignore-df`, `fwmark` and the four erspan words (`erspan`, `erspan_ver`, `erspan_dir`, `erspan_hwid`). The erspan words exist only for erspan; on gre and gretap they get the usage text, rc 1. `erspan_dir`'s value itself is parsed with `matches`.
+- **No duplicate checks.** A repeated word overwrites the earlier one.
+- **ip's own checks.** `ip` refuses a multicast `remote` with no `local` ("A broadcast tunnel requires a source address", returned, 1), and in that case fills in the keys from the group address. It checks `erspan` (1..2^20-1), `erspan_ver` (≤2), `ttl` (u8, base 0), `tos` (hex, ≤ff) and `fwmark`/`encap-*` with `invarg` (255).
+- **Set prefetch.** On a set (no `NLM_F_CREATE`), `gre_parse_opt` first sends an `RTM_GETLINK` for the device and prefills every `IFLA_GRE_*` the kernel reports, so a set sends the device's current values plus the changed words. This matters because the kernel rebuilds the parameters from the message on every change (`ipgre_netlink_parms` starts with a `memset`). It has three consequences:
+  - A set on a device with no `INFO_DATA` (`d0`) fails in `ip` ("Failed to get existing tunnel info.", 1).
+  - A set on an `external` device prefills `metadata`, so only `COLLECT_METADATA` is sent and the other words are silently dropped.
+  - `remote any` on a set really clears the remote.
+- **Kernel validate.** It runs on adds and sets.
+  - All three `validate`s accept `data == NULL`, so `add_no_option` creates a tunnel (remote and local any, ttl inherit, and `nopmtudisc`, because `ipgre_netlink_parms` returns before it sets DF).
+  - gre refuses only `GRE_VERSION`/`GRE_ROUTING` flags (which `ip` can't send) and metadata with an encap (which `ip` can't send either: `external` drops the encap).
+  - gretap adds the `IFLA_ADDRESS` check (6 bytes, a valid unicast MAC) and a nonzero-remote check. `ip` can't reach the remote check, because it never sends a zero `REMOTE`.
+  - erspan adds, unless the version is 0 or `external` is given, that the OR of `IFLAGS` and `OFLAGS` is exactly `seq|key`, and that each key fits in 10 bits.
+- **Kernel newlink and changelink.**
+  - `erspan_netlink_parms` refuses a hwid over 6 bits; `ip` can't send a bad direction or index.
+  - `ipgre_netlink_parms` refuses `pmtudisc` on a device that has `ignore-df`, checking the device's **old** `ignore_df` before it reads the new one, and refuses `ignore-df` with `pmtudisc`.
+  - `ip_tunnel_newlink` returns `-EEXIST` for a second tunnel with the same local, remote, link and key, or for a second metadata tunnel.
+  - `ipgre_changelink` refuses turning on `external` (`-EOPNOTSUPP`, with extack).
+  - `ip_tunnel_changelink` returns `-EEXIST` when the new parameters match another tunnel. For gre only (not Ethernet), it also returns `-EINVAL` when the point-to-point state would change, for example a remote going to any.
+  - `rtnl_changelink` calls `changelink` only when `INFO_DATA` is present, so a bare set is rc 0 and changes nothing. A set naming another kind is `-EOPNOTSUPP`.

+#### KC5-T02 ip6gre, ip6gretap and ip6erspan
+
+One `ip` parser serves all three kinds: `gre_parse_opt` in `ip/link_gre6.c`, with one `link_util` per kind. The kernel side is `net/ipv6/ip6_gre.c`. ip6gre and ip6gretap share `ip6gre_newlink` and `ip6gre_changelink`; ip6erspan has its own newlink and changelink, built on the same common code. The devices are `g6` (ip6gre), `gt6` (ip6gretap) and `es6` (ip6erspan), with `g7` and `gt7` as second devices. None of them is the fallback name `ip6gre0`, which a row's namespace doesn't have anyway. "base" is `remote 2001:db8::1` for ip6gre and ip6gretap, and `remote 2001:db8::1 key 10 seq` for ip6erspan.
+
+`ip` requires no word on any of the three kinds. Once any word follows `type <kind>`, `ip` sends `IKEY`, `OKEY`, `IFLAGS`, `OFLAGS`, `TTL` (64), `ENCAP_LIMIT` (4), `FLOWINFO`, `FLAGS`, `FWMARK`, `ERSPAN_VER` (1) and the four `ENCAP_*` attributes, with `ENCAP_FLAGS` set to `CSUM6`. It sends `LOCAL`, `REMOTE` and `LINK` only when they are set; `::` and `any` count as unset. With `external`, `ip` sends `COLLECT_METADATA` and nothing else. With no word, `parse_opt` isn't called and no `INFO_DATA` is sent. All three `validate`s accept `data == NULL`, so `add_no_option` creates a device (rc 0). `ip6gre_netlink_parms` then zeroes everything, so the device reads back `hoplimit inherit` (JSON `ttl` 0) and `encaplimit 0`, not 64 and 4. An ip6erspan made this way has `erspan_ver` 0 and reads back no `erspan_*` key.
+
+**Keywords.** `matches` (abbreviations accepted, first match wins): `key`, `nokey`, `ikey`, `noikey`, `okey`, `nookey`, `seq`, `noseq`, `iseq`, `noiseq`, `oseq`, `nooseq`, `csum`, `nocsum`, `icsum`, `noicsum`, `ocsum`, `noocsum`, `remote`, `local`, `dev`, `ttl`/`hoplimit`/`hlim` and `tos`/`tclass`/`dsfield`. So `k` is `key`, `no` is `nokey`, `d` is `dev`, `h` is `hoplimit` and `tc` is `tclass`. Everything else is `strcmp`: `flowlabel`/`fl`, `dscp`, `noencap`, `encap`, `encap-sport`, `encap-dport`, `[no]encap-csum`, `[no]encap-udp6-csum`, `[no]encap-remcsum`, `external`, `fwmark`, `[no]allow-localremote`, `encaplimit`, `erspan`, `erspan_ver`, `erspan_dir` and `erspan_hwid`. Inside `erspan_dir`, the values `ingress` and `egress` are `matches`. Only these keywords take a "no" form; `noexternal` doesn't exist. No keyword in the file checks for repeats (no `duparg`), so a repeated word is accepted and the last one wins.
+
+**Value parsing.**
+- `tclass` is parsed as hex, so `20` is 0x20.
+- `flowlabel` is parsed as hex and must be at most 0xfffff.
+- `hoplimit`, `encaplimit`, `fwmark` and the ports take any base.
+- `tclass`, `flowlabel` and `fwmark` also accept `inherit`; `encaplimit` accepts `none`; `encap-sport` accepts `auto`.
+- A key containing a dot is parsed by `get_addr32`, whose failure is `exit(1)`. Any other key goes through `get_unsigned`, whose failure is `exit(-1)`, so 255.
+- `remote` and `local` are parsed with `AF_INET6`, so an IPv4 address is `get_addr`'s `exit(1)`.
+
+**A set fetches first.** When there is no `NLM_F_CREATE`, `gre_parse_opt` sends an `RTM_GETLINK` for the device before it parses any word, and fills its variables from every `IFLA_GRE_*` the answer carries. The capture shows that request and answer before the `RTM_NEWLINK`. A set therefore sends the device's whole configuration plus the changed words. Two side effects follow:
+- `FLAGS` carries the `IP6_TNL_F_CAP_*` bits the kernel computed.
+- `ENCAP_SPORT` and `ENCAP_DPORT` come back byte-swapped. The answer's big-endian value is read with `rta_getattr_u16` and then passed through `htons` again, so on the x86_64 guest port 4660 becomes 13330.
+
+Two more cases:
+- A set with no word fetches nothing and sends no `INFO_DATA`. `rtnl_changelink` then skips `changelink`, so the set is rc 0.
+- A set on a device whose answer has no `INFO_DATA` (a dummy) fails with "Failed to get existing tunnel info.", and `parse_opt` returns -1, so rc 1.
+
+**What the kernel checks.**
+- **ip6gre's `validate`** refuses only `GRE_VERSION` and `GRE_ROUTING`, which `ip` can't send. It accepts and ignores every `ERSPAN_*` attribute, so `erspan_ver 0` is rc 0 on ip6gre.
+- **ip6gretap's `validate`** also refuses a `REMOTE` of `::`. `ip` never sends one, because it omits an unspecified address on an add, and on a set too, since `get_addr_rta` marks a fetched `::` as unspec. So `remote ::` is rc 0 on ip6gretap.
+- **ip6erspan's `validate`** works on the union of `IFLAGS` and `OFLAGS`, which must be exactly `GRE_SEQ|GRE_KEY` unless `COLLECT_METADATA` is present. Keys must fit `ID_MASK` (0x3ff). `ERSPAN_VER`, when present, must be 1 or 2. For version 2, `hwid` must fit 6 bits (0x3f). `ip`'s own checks (an index of 1 to 0xfffff, a version of at most 2, `ingress`/`egress`) pre-empt the kernel's index and direction checks.
+- **`newlink`** refuses a second device whose local, remote, `i_key`, link and `dev->type` all match an existing one (`-EEXIST`). It also refuses a second `external` device: ip6gre and ip6gretap share one `collect_md_tun` slot, so an `external` ip6gretap is refused beside an `external` ip6gre, while ip6erspan has a slot of its own.
+- **`changelink`** returns `-EEXIST` when the new parameters belong to another device. `ip6gre_tunnel_locate` always searches with `ARPHRD_IP6GRE`, so an ip6gretap set that collides goes through (rc 0). `changelink` never copies `collect_md`, so a set of `external` is accepted but leaves the device not external, with its other parameters zeroed.
+- **A set naming another kind** is `-EOPNOTSUPP`, from `rtnl_changelink`.
+- **`encap fou` and `encap gue`** need `fou6`'s `ip6_tnl_encap_ops`. `fou6` isn't in `late_modules`, and nothing loads it on demand, so `ip6_encap_hlen` returns `-EINVAL` (rc 2). This is unlike gre, whose IPv4 ops come with `fou`.
+
+**Read-back forms.**
+- Keys print through `inet_ntop`, so `key 42` reads back `ikey 0.0.0.42 okey 0.0.0.42`.
+- `tclass` prints as `0x%02x`, `flowlabel` as `0x%05x` and `fwmark` as `%#x`.
+- `encaplimit none`, `tclass inherit`, `flowlabel inherit`, `fwmark inherit`, `dscp inherit` and `allow-localremote` are JSON booleans named `ip6_tnl_f_*`.
+- An `encap` of none isn't printed, so `ENCAP_*` values sent with it show only in the capture.
+- An ip6erspan device always reports `okey`, because `fill_info` sets `GRE_KEY` in `o_flags` for versions 1 and 2. At version 1 it reports `erspan_index`, even when the index is 0.

+
+#### KC5-T03 ipip and sit
+
+One parser, two kinds: `ip/link_iptnl.c` serves both, and checks `lu->id` for sit's extras. The devices are `ip0` (ipip) and `st0` (sit), with `ip1` and `st1` as the second device in the conflict rows; none is a fallback name (`tunl0`, `sit0`), and the row's namespace has no fallback device anyway. Neither kind needs a word. With none, `parse_opt` isn't called and no `INFO_DATA` is sent, and both `validate`s accept `!data` (`net/ipv4/ipip.c:441`, `net/ipv6/sit.c:1482`). So `add_no_option` is rc 0: a wildcard tunnel (remote any, local any) with the kernel's own defaults. For ipip that is mode `ipip`, `ttl inherit`, `nopmtudisc`; for sit it is mode `ip6ip`, `ttl 64`, `nopmtudisc`. Once any word is given, `ip` always sends `PROTO` (0, read back as `any`, unless `mode` is given), `PMTUDISC` 1, `TOS`, `TTL` 0, `LINK`, `FWMARK` and the four `ENCAP_*`; for sit it also sends `FLAGS` and the 6rd prefixes, and for ipip neither. So `add_default` reads back `any … ttl inherit pmtudisc` on both kinds. `dev` and `dsfield` are `matches`. Every other keyword is `strcmp`: `mode` and its values, `remote`, `local`, `ttl`/`hoplimit`/`hlim`, `tos`/`tclass`/`tc`, `[no]pmtudisc`, `isatap` (sit only), `noencap`, `encap fou|gue|none`, `encap-sport` (`auto` or a number), `encap-dport`, `[no]encap-csum`, `[no]encap-udp6-csum`, `[no]encap-remcsum`, `external`, `6rd-prefix`, `6rd-relay_prefix`, `6rd-reset` and `fwmark`. The help text's `[no]encap-csum6` is no keyword; the parser's word is `encap-udp6-csum`. There's no `noexternal`. No keyword is checked for repeats; the last value wins. `tos` is hex (`rtnl_dsfield_a2n`), `ttl`, `fwmark` and the ports are base 0, and `ttl` nonzero with `nopmtudisc` is `ip`'s `exit(-1)`. `mode ip6ip` and `isatap` are sit's words. On ipip, `mode ip6ip` is `invarg` and `isatap` is "unknown". The 6rd words are parsed for both kinds and sent for sit alone, so on ipip they are accepted and dropped. A bad 6rd prefix is `get_prefix`'s `exit(1)`, so the status is 1, not the `invarg` written after it.
+
+**What the first VM run changed.** Two things the draft missed. `6rd-reset` segfaults `ip`: `link_iptnl.c:288` passes the literal `"2002::/16"` to `get_prefix`, and `get_prefix_1` writes a NUL over its `/`, so the write lands in read-only memory. No capture can come of it, so the row is gone. And sit's wildcard can't be set: with no `INFO_DATA`, `ipip6_netlink_parms` gives it `ttl 64` with no DF, a set's prefetch seeds those, and `ip` refuses its own combination before netlink. So `set_external_wildcard` and `set_remote_on_wildcard` are 255. `set_remote_on_inherit` keeps the kernel's point-to-point refusal on a wildcard made with `ttl inherit`, which sends `PMTUDISC` 1.
+
+**The set prefetch.** On a set (no `NLM_F_CREATE`), `parse_opt` first sends an `RTM_GETLINK` for the device and seeds every variable from the reply: local, remote, the 6rd prefixes, ttl, pmtudisc, tos, flags, link, proto, the four encap values, metadata and fwmark (`link_iptnl.c:101-182`). It then applies the words, so a set sends what the device already has plus the change. Three consequences are pinned. A `nopmtudisc` set is refused by `ip` on a device made with a ttl, and accepted on one without. `remote any` sends no `REMOTE`, so the kernel reads it as 0. Any set on an `external` device carries `COLLECT_METADATA` again.
+
+**What the kernel checks.** On an add: `-EEXIST` when a tunnel with the same local, remote and link exists, or a second `external` ipip (`ip_tunnel_newlink`, `ipip6_newlink`). Both `validate`s refuse a protocol other than ipip/mpls/any (sit: ipv6 too), but `ip` can't send one, so no row reaches them. On a set: ipip refuses `external` (`-EINVAL`). Both kinds refuse to add or drop a remote (the device's `IFF_POINTOPOINT` must agree with the new remote), and refuse a remote that collides with another tunnel (`-EEXIST`). ipip also refuses a change to a multicast remote (`IFF_BROADCAST`). Neither `ip_tunnel_update` nor `ipip6_tunnel_update` copies the protocol or sit's `i_flags`, so a set of `mode` or `isatap` is accepted and changes nothing. sit ignores `COLLECT_METADATA` (it isn't in `ipip6_policy`), so `external` makes an ordinary sit device. The guest kernel (7.3, `# CONFIG_IPV6_SIT_6RD is not set`) leaves the 6rd attributes out of the policy and ignores them. The 6rd rows are accepted, none reads back, and the over-long prefix the 6RD code would refuse is accepted: `sit/add_6rd_overlong` is the config's canary. `fou` is in `late_modules`, so `encap fou` and `encap gue` find their ops. "base" is `remote 10.0.0.1`.

+
+#### KC5-T04 ip6tnl
+
+The device is `t6`, with `t7` as the second device in the conflict rows. `ip6tnl0` is the fallback name, and no row's namespace has it. `ip/link_ip6tnl.c` requires no word. With none, `ip6_tnl_validate` accepts `!data` and `ip6_tnl_netlink_parms` zeroes everything, so `add_no_option` is rc 0 and reads back `any remote any local any hoplimit inherit encaplimit 0`. Once any word is given, `ip` always sends `PROTO` (0, `any`, unless `mode` is given), `TTL` 64, `ENCAP_LIMIT` 4, `FLOWINFO`, `FLAGS`, `LINK`, `FWMARK` and the encap four, with `ENCAP_FLAGS` defaulting to `CSUM6`. So `add_default` reads `any remote 2001:db8::1 local any hoplimit 64 encaplimit 4 tclass 0x00 flowlabel 0x00000`. `dev` and `dsfield` are `matches`. `dev` is tested first, so `d` is `dev`; `dscp` doesn't match `dsfield`, so it reaches its own branch. Everything else is `strcmp`: `mode ip6ip6|ipip6|any` with the aliases `ipv6/ipv6`, `ip/ipv6`, `ipv4/ipv6`, `ip4ip6`, `any/ipv6`; `remote`, `local`, `ttl`/`hoplimit`/`hlim`, `encaplimit`, `tos`/`tclass`/`tc`, `flowlabel`/`fl`, `dscp inherit`, `fwmark` (a number or `inherit`), `[no]allow-localremote`, the encap words as in `link_iptnl.c`, and `external`. No keyword is checked for repeats; the last value wins. `tclass` and `flowlabel` are hex (base 16), and `hoplimit` and `fwmark` base 0. `encaplimit`'s value is never refused: `get_u8(…) < -1` can't be true, and a bad value leaves `encap_limit` to an uninitialized `__u8` (`link_ip6tnl.c:196-200`). That reads back as garbage, so no row sends one. `encap` takes a type, so `encap 4` is `invarg` and `encapl 4` is "unknown".
+
+**The set prefetch.** Like `link_iptnl.c`, a set first fetches the device and seeds local, remote, hoplimit, encaplimit, flowinfo, flags, link, proto, metadata and fwmark (`link_ip6tnl.c:97-153`). It does **not** read the encap attributes, so every non-`external` set sends encap none/`CSUM6`/ports 0 and resets any encap the device had. No row can show it: no encapped ip6tnl can be made (below). A set on an `external` device carries `COLLECT_METADATA` again.
+
+**What the kernel checks.** On an add, `-EEXIST` for a second tunnel with the same local, remote and link (two wildcards included) or a second `external` one (`ip6_tnl_newlink`). The encap ops come from `fou6`, which `late_modules` doesn't load and nothing pulls in: `fou6` depends on `ip6_tunnel`, not the reverse. So `encap fou` is `ip6_encap_hlen`'s `-EINVAL`, and `encap none` passes. On a set, `ip6_tnl_changelink` refuses `external` (`-EINVAL`) and a collision with another tunnel (`-EEXIST`), and has no point-to-point check. `ip6_tnl_change` copies the protocol, unlike ipip's and sit's updates, so `set_mode` reads back the new mode. "base" is `remote 2001:db8::1`.

+
+#### KC5-T05 vti, vti6 and xfrm
+
+Three IPsec kinds; the devices are `vt0` (vti), `v6` (vti6) and `xf0` (xfrm), so no row uses the fallback names `ip_vti0` or `ip6_vti0`, and a second device is `vt1`, `v7` or `xf1`. **vti and vti6** share one parser shape (`ip/link_vti.c`, `ip/link_vti6.c`): `key`, `ikey`, `okey`, `remote`, `local` and `dev` are `matches`, in that order, so `k`, `i`, `o`, `r`, `l` and `d` each pick their keyword; `fwmark` is `strcmp`. No word takes a `no` form, and nothing is required. Once any word follows `type`, `ip` always sends `IKEY`, `OKEY` and `FWMARK` (0 when not given), `LOCAL`/`REMOTE` only for a real address (`any` sends neither), and `LINK` only when nonzero. `key` sets both keys, and a later `ikey`/`okey` overrides its half. A key with a dot goes through `get_addr32` (bad: `exit(1)`), and any other key through `get_unsigned` (bad: `exit(-1)`, 255). **On a set**, both files first send a `GETLINK` for the device and prefill every value it already has (`link_vti.c:65-110`), so a set sends what the device has plus the changed words; a device without vti's `INFO_DATA`, such as a dummy, fails the prefetch: "Failed to get existing tunnel info.", status 1. Neither kernel `validate` checks anything (`return 0`), so `add_no_option` creates a tunnel with remote any and local any (status 0), and a bare `set` sends no `INFO_DATA` and reaches no `changelink` (status 0). vti's kernel side is `ip_tunnel`'s: `ip_tunnel_find` matches on local, remote, lower and type, but ignores the keys (a vti tunnel never sets `TUNNEL_KEY`, so `ip_bucket` hashes key 0 and `ip_tunnel_key_match` passes), so a second tunnel that differs only by key is `-EEXIST`; `ip_tunnel_changelink` also refuses (`-EINVAL`) a change that would add or remove the remote, because `IFF_POINTOPOINT` would flip. vti6's `vti6_locate` matches on local and remote only (a different lower doesn't separate two tunnels), and `vti6_changelink` has no point-to-point check. **xfrm** (`ip/link_xfrm.c`) has no prefetch. `dev` and `if_id` are `matches`, `external` is `strcmp`. `ip` requires `if_id` (`missarg`, 255) unless `external` is given, refuses `if_id 0` with `invarg` (255), and refuses `external` with `if_id` or `dev` (returned, 1). The kernel (`net/xfrm/xfrm_interface_core.c`) refuses a missing `if_id` ("if_id must be non zero") on add and set, an `if_id` already in use and a second `external` device (`-EEXIST`), a set that adds, removes or changes the `collect_md` flag, and a set whose lower differs from the device's (`-EINVAL`, in `xfrmi_change`). Because there's no prefetch, a set on an `xf0` made with `dev d0` must name `dev d0` again. Readbacks: vti and vti6 print `remote`/`local` (`any` when 0), `dev`, and `ikey`/`okey` as dotted quads (for vti6 too) and `fwmark` as hex, each only when nonzero; xfrm prints `if_id` as hex, or just `external`.

+
+### KC6 — The remaining kinds' captures
+
+hsr, netkit, vrf and vrf_slave, vxcan, batadv, and the option-less ifb, nlmon, vcan, team and team_slave. The KC0 probe created every one of them (`late/kinds`). Four tasks: KC6-T01 hsr (`iplink_hsr.c`); KC6-T02 netkit (`iplink_netkit.c`); KC6-T03 vrf, vrf_slave and vxcan (`iplink_vrf.c`, `iplink_vxcan.c`); KC6-T04 batadv and the five kinds `ip` has no parser for (`iplink_batadv.c`, `iplink_ifb.c`, `iplink_nlmon.c`, `iplink_vcan.c`, `iplink_team.c`), which closes KC6.
+
+**Shared shape.** Rows go in `kind-write-corpus.exp` after xfrm's, under `kinds/<kind>/`, with KC5's shape. A row whose words must come before `type` (`mtu`, `address`, `up`, `numtxqueues`, `master`) is written with `row` and its whole command. The devices are `hs0` (hsr, slaves `d0` and `d1`, interlink `d2`), `nt0` (netkit), `vr0` (vrf), `vc0` (vxcan), `bat0` (batadv), `ib0` (ifb), `nm0` (nlmon), `vn0` (vcan) and `tm0` (team); a second device is `hs1`, `nt1`, `vr1` and so on. No name starts with `if` and a digit, which `ll_name_to_index` would read as an ifindex.
+
+**What these files add to KC5's rules:**
+- **`ip` hands a kind only the words after `type`.** `iplink_parse` stops at `type K` (`ip/iplink.c:1090-1094`), and `iplink_modify` nests `INFO_DATA` (`INFO_SLAVE_DATA` for a `_slave` kind) only when the kind has a `parse_opt` and words follow (`:1457`). So a bare `type K` sends no `INFO_DATA` for any kind, and a generic word written after `type K` belongs to the kind.
+- **A kind with no `parse_opt` takes no words.** ifb, nlmon, vcan, team, team_slave and vrf_slave have only `print_help`. A word after their `type` is "Garbage instead of arguments", status 1 (`:1469-1472`), unless it is a prefix of `help`, which is `usage()`, `exit(-1)`, 255 (`:1467-1468`).
+- **`nodev` returns; it doesn't exit.** `nodev()` prints and returns -1 (`lib/utils.c:844-848`), so a set on a missing device is status 1 (`iplink.c:1374`). The tunnel parsers' `exit(nodev(…))` was 255; `iplink.c`'s is 1. `master nosuch` and `vrf nosuch` are `invarg`s, 255 (`:1059-1061`).
+- **A set of only `type K` reaches no kind code.** It sends `IFLA_INFO_KIND` alone, and `rtnl_changelink` checks the kind and `changelink` only when `INFO_DATA` is present (`net/core/rtnetlink.c:3866-3868`), so it is 0 even for a mismatched kind. With `INFO_DATA`, a kind without `changelink` (hsr, vrf, vxcan, batadv) is `-EOPNOTSUPP`.
+- **`validate` runs before the create or change split** (`rtnetlink.c:4174`), so a value `validate` refuses on a set is that refusal, not `-EOPNOTSUPP`.
+- **A name lookup costs datagrams.** `ll_name_to_index` (hsr's slaves and interlink, `master`, `vrf`, a set's device) asks with its own `RTM_GETLINK`. Floors are minimums, so the rows keep KC5's floors.
+
+#### KC6-T01 hsr
+
+`ip/iplink_hsr.c` (`hsr_parse_opt`, lines 47-106) and `net/hsr/hsr_netlink.c`. `supervision`, `version`, `proto`, `slave1` and `slave2` are `matches`, in that order, so `s` is `supervision`, `sl` is `slave1` and `v`/`p` are `version`/`proto`; `interlink` is `strcmp`, and `help` is `matches`, returning 1. The numbers are `get_u8` base 0 (`invarg`, 255, when bad or over 255), and the devices are `ll_name_to_index` (`invarg` "No such interface", 255). Nothing is sent unless named, and nothing is checked for repeats. **`ip`'s version and proto checks test `get_u8`'s return, not the value** (`:64-66`, `:71-73`): `get_u8(…) == 0 || get_u8(…) == 1` is true for any u8, so `version 2` and `proto 2` reach the kernel, which refuses them. The kernel has no `validate` and no `changelink`; `hsr_newlink` refuses with `-EINVAL` and an extack: no `INFO_DATA` or no `slave1` ("No slave devices specified"), no `slave2`, the same slave twice, an interlink equal to a slave, `proto` ≥ 2, `version` with PRP, and `version` > 1. `hsr_check_dev_ok` refuses loopback and non-Ethernet slaves. Readbacks: `slave1`, `slave2`, `interlink` when set, `supervision 01:15:4e:00:01:XX`, `sequence`, `version` (not for PRP) and `proto`. `base` is `slave1 d0 slave2 d1`, and every row's pre makes `d0` and `d1` (and `d2` for the interlink rows).

+#### KC6-T02 netkit
+
+`ip/iplink_netkit.c` (`netkit_parse_opt`, lines 46-150) and `drivers/net/netkit.c`. Every keyword is `strcmp`. On a set, the words after `peer` go through `iplink_parse` without `NLM_F_CREATE`, which looks the name up (`iplink.c:1365-1376`), so a set naming the peer names one the pre made (`nt1`), and an unknown name is `nodev`'s 1. `mode l3|l2` sends `MODE` (anything else returns 1, a second `mode` is `duparg`, 255); `forward`/`blackhole` send `POLICY` before `peer` and `PEER_POLICY` after; `scrub none|default` sends `SCRUB` before `peer` and `PEER_SCRUB` after (anything else returns 1); a second `peer` is `duparg`. After `peer`, the first word that isn't one of these opens `PEER_INFO` and `iplink_parse` takes every word left, so `peer name nt1 blackhole` reads `blackhole` as a device and exits "both name and dev" (255), and `peer black` names the peer `black`. An unknown word before `peer` returns 1. 7.2.0 has no `headroom`, `tailroom` or `pairing`. The parser keeps state in statics, so its rows never run under `ip -batch`. The kernel's policy caps `MODE`, `SCRUB` and `PEER_SCRUB` at 1; the defaults are l3, forward and scrub default on both ends, with the peer named by the kernel. `netkit_new_link` refuses an address in l3 mode (`-EOPNOTSUPP`), registers the peer first (so a peer named like the device is `-EEXIST`), and ignores the peer's flags. **netkit has a `changelink`**, which changes only `POLICY` and `PEER_POLICY`: `MODE`, `SCRUB`, `PEER_SCRUB` or `PEER_INFO` is `-EACCES`, even unchanged, and so is any change made through the peer.

+
+**vrf** (`ip/iplink_vrf.c`, `drivers/net/vrf.c`). One keyword, `table`, `matches` (so `t`), through `rtnl_rttable_a2n`: `default`, `main` and `local` by name, else `strtoul` base 0 to `0xffffffff`; a bad or missing value is 255; no repeat check; `help` or an unknown word returns 1. The kernel requires a nonzero `TABLE` (`-EINVAL`, `vrf.c:1645`, `:1650`), allows a shared table (`strict_mode` is 0), and has no `changelink`. **vrf_slave** has no parser. A device enslaved with `master vr0` or `vrf vr0` reads back `vrf_slave table N`. The kernel refuses loopback (`-EOPNOTSUPP`) and a vrf inside a vrf (`-EINVAL`), and `add … type vrf_slave` is "Unknown device type". `vrf X` checks that X is a vrf (`invarg`, 255). **vxcan** (`ip/iplink_vxcan.c`, `drivers/net/can/vxcan.c`). The first word must be `peer` (`strcmp`); anything else prints the usage to stdout and returns 1. `peer` hands the rest to `iplink_parse` inside `VXCAN_INFO_PEER`. The kernel registers the peer first (default name `vxcan0`, so a peer named like the device is `-EEXIST`), has no `validate`, `changelink` or `fill_info`, and applies the peer's flags before the pair is linked, so `peer up` should be `-ENOTCONN`. That one is read from the code, and the VM decides it. As with netkit, a set's words after `peer` go through `iplink_parse` without `NLM_F_CREATE`, which looks the name up, so the set rows run on a `vc0` whose peer is `vc1` and name `vc1`.

+
+**Done when:** as KC2-T01.
+
+#### KC6-T04 batadv, ifb, nlmon, vcan, team and team_slave
+
+**batadv** (`ip/iplink_batadv.c`, `net/batman-adv/mesh-interface.c`). One keyword, `ra`, `matches` (so `r`), sent verbatim as the NUL-terminated `IFLA_BATADV_ALGO_NAME`, with no check and no repeat check; `help` and an unknown word return 1. It is the kernel's only `IFLA_BATADV_*` attribute. `validate` looks the name up case-sensitively among `BATMAN_IV` and `BATMAN_V` (`-EINVAL`, no extack); the default is `BATMAN_IV`; there's no `changelink` and no `fill_info`, so nothing reads back. **ifb, nlmon, vcan, team, team_slave** have no parser. Their rows are the generic words before `type`, the refusals their drivers make, and Garbage after `type`. ifb's `validate` refuses a multicast address (`-EADDRNOTAVAIL`); nlmon's refuses any address (`-EINVAL`), and its minimum MTU is 16. vcan's `ndo_change_mtu` takes 16, 72 and 76 to 2060, and refuses a change while up (`-EBUSY`). A create's MTU is checked only against the device's min and max, which vcan leaves at 0, so `mtu 100` at create should be accepted; that one is read from the code. team enslaves without teamd: `team_port_add` refuses loopback, the team itself and a port that is up, each with an extack, and `ip link add d0 up master tm0 type dummy` brings `d0` up before it sets the master, so it is refused too. A set `mtu` on vcan and the enslave rows have no `type`, so they are written whole with `row`.

+
+**Done when:** as KC2-T01. It closes KC6.
+
+### KC7 — Kind completeness gate
+
+The kind captures so far live in the scratch runs that V055, V058 and the rest compared; the committed link-write corpus is 7.1.4's (`testdata/7_1_4/link-write`), older than the kind corpus and the guest kernel. So KC7 is two tasks: KC7-T01 commits a 7.3.0 link-write corpus, and KC7-T02 is the gate that reads it.
+
+#### KC7-T01 The 7.3.0 link-write corpus
+
+One run of `nix run .#microvm-x86_64-link-write-capture -- --timeout 7200` with the default `--out`, `pkg/xtcpnl/testdata/7_3_0/link-write`, after KC6-T04. Every file it writes is committed; nothing in `7_1_4/` changes, and the tests that name `7_1_4/link-write` keep reading it. `genl/mptcp_limits_set_over` lands with the kernel's status, 0 (V004); the decision log records it. The tests that walk every pcap under `pkg/` (`TestNetlinkUniverse`, `TestAttrCoverageFloors`, `TestCaptureAttrSetIsHonest`) and the provenance tests see the new tree; whatever they report is fixed in this task, and an exclusion the corpus makes stale is removed and logged. The tests that tally every message under `testdata` through `corpusAll` (17 of them: xfrm, nsid, tcp_metrics, mptcp, seg6 and the rest) count one capture of each row, and the 7.3.0 set is a second capture of the 7.1.4 set's rows, so `corpusAll` skips `7_3_0/link-write`; the kind tests read it directly.
+
+| description | input | expected |
+|---|---|---|
+| positive: the corpus was taken in the capture VM on 7.3.0 | `7_3_0/link-write/uname` | `Linux xtcp2-vm-x8664 7.3.0 …` |
+| positive: the corpus's `ip` is the pin | `7_3_0/link-write/ip_version` | iproute2 7.2.0 |
+| negative: no exclusion is stale | `TestNetlinkUniverse` over the larger corpus | no "the exclusion is stale" problem |
+| boundary: the 7.1.4 corpus is untouched | `git diff --stat main -- pkg/xtcpnl/testdata/7_1_4` | empty |
+| positive: every kind row has its status, its request, and its readbacks exactly when the kernel saw it | `TestKindRowsComplete` over `7_3_0/link-write/kinds` | no problem |
+| negative: a row with no status, or no request | a row without `ip.rc`; one without `ip.pcap` | `no ip.rc`; `no ip.pcap` |
+| boundary: a kernel refusal is read back, an `ip` refusal isn't | rc 2 with the three readbacks; rc 255 with none | no problem |
+| corner: a readback missing, or one too many | rc 0 without the `-d -j` pcap; rc 1 with `netlink_route_getlink.pcap` | `rc 0 and no …`; `rc 1 and a …` |
+| corner: a status the corpus never plans | rc 3 | `ip.rc is 3` |
+| positive: `corpusAll` reads the 7.1.4 link-write set | `TestCorpusAllSkipsLinkWrite730` | messages under `7_1_4/link-write` |
+| negative: `corpusAll` doesn't read the 7.3.0 set | the same | none under `7_3_0/link-write` |
+| boundary: the 7.3.0 dump set beside it is still read | the same | messages under `7_3_0/dumps` |
+| corner: the kind corpus inside the skipped set isn't read either | the same | none under `7_3_0/link-write/kinds` |
+
+**Mutation check:** the rc 2 case moved to the no-readback side (the kernel-refusal boundary), the extra-readback case dropped (the one-too-many corner), and `corpusAll`'s skip dropped (the 17 tallies and the negative row).
+
+#### KC7-T02 The gate
+
+`TestLinkKindUniverse` (`pkg/xtcpnl/xtcpnl_kind_universe_test.go`), in `TestNetlinkUniverse`'s shape:
+- `linkKindUniverse`: the 46 `id`s of 7.2.0's `ip/iplink_*.c` and `ip/link_*.c`, each with the file that names it. The plan said 48; the files name 46. `macsec` and `tun` are `link_util`s too, but in `ipmacsec.c` and `iptuntap.c`, outside the plan's scope;
+- `linkKindExclusions`: can, dsa, ipoib, netdevsim, rmnet, virt_wifi and wwan, each with the decision log's reason, so 39 kinds are in scope;
+- `linkKindSources`: where a kind's rows are when they aren't `kinds/<kind>/*`. bond, bond_slave, dummy and veth have `write/` rows that predate the kind corpus and have no readbacks of their own, so each names the corpus's `-d -j` dump that shows a device of that kind: `lacp_converged/ip_link_n_json` (the converged bond, its veth ports and their `info_slave_kind` bond) for bond, bond_slave and veth, and `kinds/vrf_slave/set_master/ip_getlink_detail_json` (the enslaved dummy `d0`) for dummy;
+- `linkKindProblems(universe, excl, seen)`, a pure function the table drives, and `linkKindWalk`, which reads the 7.3.0 corpus. A kind counts as captured when one of its rows has `ip.rc` 0, an `ip.pcap`, and a `-d -j` readback whose `linkinfo` names it (`info_kind`, or `info_slave_kind` for a `_slave` kind). The walk also tries every `kinds/<kind>` directory, so a captured kind 7.2.0 doesn't name is seen.
+
+`TestLinkKindUniverse` drives `linkKindProblems`:
+
+| description | input | expected |
+|---|---|---|
+| positive: the committed corpus passes | `linkKindWalk` of `7_3_0/link-write` | no problem; 39 of 46 captured, 7 excluded |
+| negative: an in-scope kind with no row | the walk without `netkit` | `netkit: no accepted row with a -d readback` |
+| negative: an exclusion with no reason | `can` excluded with `""` | `can: excluded with no reason` |
+| boundary: a kind citing no source | `vrf` with no file | `vrf: cites no iproute2 source` |
+| corner: an exclusion the corpus contradicts | `can` excluded and captured | `can: captured and excluded; the exclusion is stale` |
+| corner: a captured kind 7.2.0 doesn't name | `foo` captured | `foo: captured but not a 7.2.0 kind` |
+| corner: an exclusion of a kind 7.2.0 doesn't name | `foo` excluded | `foo: excluded but not a 7.2.0 kind` |
+| corner: a kind listed twice | `vrf` twice | `vrf: listed twice` |
+
+`TestLinkKindCaptured` drives the capture rule over built rows:
+
+| description | input | expected |
+|---|---|---|
+| positive: an accepted row whose readback names its kind | `kinds/vxcan/add` at 0, `info_kind` vxcan | captured |
+| negative: an accepted row with no readback | the same without `ip_getlink_detail_json` | not captured |
+| negative: an accepted row with no request | the same without `ip.pcap` | not captured |
+| boundary: one accepted row is enough | one row at 0 beside rows at 2 and 255 | captured |
+| boundary: refused rows alone are not | rows at 2 and 255 whose readbacks name vxcan | not captured |
+| corner: the readback names another kind | `kinds/vxcan/add` whose readback says `vrf` | not captured |
+| corner: a slave kind matches its slave kind | `bridge_slave`'s readback, `info_slave_kind` bridge | captured |
+| corner: a slave kind's master device is not its capture | `bridge_slave`'s readback, `info_kind` bridge only | not captured |
+| corner: a readback that isn't JSON | `ip`'s text output | not captured |
+| corner: a `write/` kind reads its shared readback | `write/add_veth` at 0, `lacp_converged/ip_link_n_json` naming veth | captured |
+
+**Mutation check:** the stale-exclusion case dropped (the stale corner), the `_slave` match dropped (the four slave kinds fail the positive row), the `ip.rc` filter dropped (the refused boundary).
+
+### KP0 — `inet` devconf codec
+
+An encoder and decoder for `IFLA_AF_SPEC` → `AF_INET` → `IFLA_INET_CONF`. One task. The two directions don't share a shape, and the codec keeps them apart:
+- **The request** (`iplink_parse_inet`, `ip/iplink.c:572-860` at `v7.2.0`): `IFLA_AF_SPEC` and `AF_INET` are plain `addattr_nest`s, and `IFLA_INET_CONF` carries `NLA_F_NESTED` (type `0x8001`). Inside are u32 attributes typed by devconf id (`IPV4_DEVCONF_*`, `include/uapi/linux/ip.h`), in argument order, repeats kept: `inet_repeated` sends `forwarding` twice. The kernel parses them with `inet_devconf_policy` (`net/ipv4/devinet.c`).
+- **The dump** (`inet_fill_link_af`): `IFLA_INET_CONF` without `NLA_F_NESTED`, a raw array of `IPV4_DEVCONF_MAX` u32s, 132 bytes on 7.3.0. Entry `i` is devconf id `i + 1`. This is the 140-byte `AF_INET` entry `setAddrGenMode` skips.
+
+#### KP0-T01 The `inet` devconf codec
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_inet_devconf.go`:
+- `InetDevconfParams`: the 32 params `ip` writes, in `iplink_parse_inet`'s order, each `{ID, Name, OnOff}`. Names are `ip`'s keywords (`disable_xfrm` is `IPV4_DEVCONF_NOXFRM`, `arp_filter` is `IPV4_DEVCONF_ARPFILTER`). `mc_forwarding` (2) has no keyword, and the policy makes it `NLA_REJECT`. 23 params are on/off and 9 numeric: rp_filter, tag, medium_id, force_igmp_version, arp_announce, arp_ignore, arp_accept and the two unsolicited report intervals. KG0's keyword chain reads this table.
+- `InetDevconfSetting{ID uint16; Value uint32}`. medium_id's -1 is `0xffffffff`, as `addattr32` sends it.
+- `LinkAttrInetDevconf(settings []InetDevconfSetting) (LinkAttr, error)`: the whole `IFLA_AF_SPEC` attribute, so the caller places it in `LinkWrite.Attrs` in argument order. `inet_then_mtu` sends it before `IFLA_MTU`. Errors:
+  - `ErrInetDevconfEmpty` for no settings, because `ip` never sends an empty nest: a bare `inet` is `incomplete_command`.
+  - `ErrInetDevconfID` for id 0 or above `IPV4_DEVCONF_MAX` (33). The codec doesn't refuse 2; the kernel does.
+- `ParseInetDevconfRequest(afSpec []byte) ([]InetDevconfSetting, error)`: the request direction. Settings come back in wire order. A family other than `AF_INET` is skipped. An inner attribute shorter than 4 bytes is an error, which is the kernel's `NLA_U32` check.
+- `ParseInetDevconfValues(afSpec []byte) ([]uint32, bool, error)`: the dump direction, `len/4` values. A kernel with more ids sends more, and they're kept. `false` means no `AF_INET` entry or no `IFLA_INET_CONF` in it. A length that isn't a multiple of 4 is an error.
+
+**Sources.** The KC1 rows are in `tdLinkWrite_7_3_0 + "/rtnl/inet_*"`, read directly, since `corpusAll` skips the 7.3.0 link-write set (KC7-T01). The requests: the `RTM_NEWLINK` with `NLM_F_REQUEST` in each row's `ip.pcap`. The dumps: the `RTM_NEWLINK` answer in each row's `netlink_route_getlink_detail.pcap`.
+
+`TestInetDevconfEncode`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each kernel-answered KC1 row's request | the 11 rows at 0 or 2, their settings as the table in [KC1-T01](#kc1-t01-inet-devconf-write-rows) sends them | `IFLA_AF_SPEC` byte-identical to the one in the row's `ip.pcap` |
+| positive: several params, in argument order | `inet_several`'s four | ids 1, 3, 8, 19 in that order, `IFLA_INET_CONF` length 36 |
+| negative: no settings | `nil` | `ErrInetDevconfEmpty` |

+| corner: a repeated id is kept | `inet_repeated`'s two settings | both attributes, `forwarding` 1 then 0 |
+| corner: medium_id -1 | `{14, 0xffffffff}` | the bytes of `inet_medium_id_neg1`'s request |
+
+`TestInetDevconfRequestParse`:
+
+| description | input | expected |
+|---|---|---|
+| positive: every KC1 request decodes to what was sent | the 11 rows' `IFLA_AF_SPEC` | each row's settings |
+| positive: round trip | `ParseInetDevconfRequest(LinkAttrInetDevconf(s).Payload)` over the encode table's settings | `s` |
+| negative: a 3-byte inner attribute | built | an error |

+
+`TestInetDevconfValues`:
+
+| description | input | expected |
+|---|---|---|
+| positive: every devconf id reads back what `inet_every_param` sent | that row's `getlink_detail` answer for `d0` | 33 values; each of the 32 ids holds `INET_EVERY`'s value; id 2 (mc_forwarding) is 0 |
+| positive: the last of a repeated param wins | `inet_repeated`'s answer | id 1 is 0 |
+| negative: a refused row changes nothing | `inet_rp_filter_over`'s answer | id 8 (rp_filter) is the namespace default it had before |
+| negative: a 131-byte array | built | an error |

+| corner: medium_id -1 reads back as `0xffffffff` | `inet_medium_id_neg1`'s answer | id 14 is `0xffffffff` |
+
+**Benchmarks:** `BenchmarkParseInetDevconf`, with sub-benchmarks `request` (`inet_every_param`'s `IFLA_AF_SPEC`) and `values` (that row's dump entry), run with `-benchmem`; the allocations per op go in the ledger row.
+
+**Mutation check:** the `NLA_F_NESTED` bit dropped (the nest-flag corner and the byte-identical row); repeats deduplicated (the repeated corner); `ParseInetDevconfValues` reading id `i` at index `i` (the every-param row).
+
+**Done when:** the tables pass with `go test -count=1 -race ./pkg/xtcpnl/`, `go vet` passes, the mutants are killed, and lint-baseline and netlink-audit pass.
+
+### KP1 — Bridge parsers
+
+Two tasks, one per kind, each following `pkg/xtcpnl/xtcpnl_bond.go`: an option table, a decoder from `setLinkInfoNest`'s blob into a `LinkInfo` field, and an encoder through `putBondSetting`'s pattern. The source is the KC2 rows in `tdLinkWrite_7_3_0 + "/kinds/bridge"` and `"/kinds/bridge_slave"`, read directly (`corpusAll` skips the set). A row's request is the `RTM_NEWLINK` in its `ip.pcap`, and its dump is the `RTM_NEWLINK` answer that carries `IFLA_LINKINFO`, not the name lookup's. The `-d -j` readback is the oracle for every value, compared with the dump in its own pcap, `netlink_route_getlink_detail_json.pcap`: the text and JSON readbacks are two `ip` runs, and the bridge's `gc_timer` moves between them (148.48 against 148.49 in `set_ageing_time`).
+
+#### KP1-T01 The bridge parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_bridge.go`:
+- **`BridgeOptions`:** `BridgeOptionSpec{Keyword, JSON, ID, Wire, Bit, Names, Match, ReadOnly}` rows in `bridge_print_opt`'s order (`ip/iplink_bridge.c` at `v7.2.0`). It covers the 48 attributes it prints, `IFLA_BR_MULTI_BOOLOPT` as one row per bit, plus `fdb_flush`, which is write-only: 53 rows. `JSON` is the `-j` key where it differs from the keyword (`root_id`, `group_addr`, the `*_cnt` and `*_intvl` keys). `Match` reuses `BondMatch`. `Match` is `matches` or `strcmp`, per `bridge_parse_opt`: `stp_mode`, `no_linklocal_learn`, `mst_enabled`, `fdb_max_learned`, `mcast_vlan_snooping`, `mdb_offload_fail_notification` and `fdb_local_vlan_0` are `strcmp`; the rest are `matches`. KG1 reads `Match`.
+- **The wires:**
+  - u8, u16, u32 and u64;
+  - `vlan_protocol`, a u16 in network order: `ll_proto_a2n` returns it byte-swapped, and `addattr16` copies it, so 802.1Q is `81 00` on the wire;
+  - the flag `fdb_flush`, with no payload;
+  - `group_address`, 6 bytes;
+  - `bridge_id` and `root_id`, `struct ifla_bridge_id`: 2 priority bytes, then 6 address bytes;
+  - the four timers, u64 in centiseconds;
+  - `IFLA_BR_MULTI_BOOLOPT`, `struct br_boolopt_multi`, `optval` then `optmask`, u32 each, which carries `no_linklocal_learn`, `mcast_vlan_snooping`, `mst_enabled`, `mdb_offload_fail_notification` and `fdb_local_vlan_0` as bits;
+  - `IFLA_BR_MCAST_QUERIER_STATE`, a read-only nest of `BRIDGE_QUERIER_*`.
+- **`IflaBrStpMode`** = 50. x/sys/unix v0.49 stops at `IFLA_BR_FDB_MAX_LEARNED` (49). `stp_mode`'s names are `auto`, `user` and `kernel`.
+- **The British spelling.** misspell reads string literals and upper-case tokens, so the keyword is the one constant `BridgeKeywordAgeingTime`, assembled from two halves, and the id is `IflaBrAgeingTime` = 4 rather than x/sys/unix's name. No lint exclusion is added.
+- **The decoder:** `BridgeInfo` (`Value(id)`, plus `BridgeID`, `RootID`, `GroupAddr`, `BoolOpts` and `QuerierState`), `ParseBridgeInfoData(nest []byte) *BridgeInfo`, a `LinkInfo.Bridge` field, and a `setLinkInfoNest` branch. The values are an array indexed by id, not bond's map. The new field changes the JSON digests of `pkg/linkmonitor`'s replay goldens, which are regenerated as `1ca4c9bd` did for `HasLinkInfo`.
+- **The encoder:** `EncodeBridgeInfoData(settings []BridgeSetting) ([]byte, error)`. Settings go in argument order, and `IFLA_BR_MULTI_BOOLOPT` goes last whatever its words' positions: `bridge_parse_opt` adds it after the loop, once, and only when `optmask` is set.
+- **The benchmark:** a `BenchmarkParseBridgeInfoData` over `add_default`'s blob.
+
+`TestParseBridgeInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: a bare bridge's dump | `add_default`'s answer for `br0` | forward_delay 1500, hello_time 200, max_age 2000, ageing_time 30000, priority 32768, stp_mode auto, vlan_protocol 0x8100, group_address `01:80:c2:00:00:00`, mcast_hash_max 4096, every value the `-d -j` readback's |
+| positive: every accepted row's dump agrees with its `-d -j` readback (`TestBridgeDumpMatchesReadback`, a subtest per row) | the 50 `kinds/bridge` rows at 0 | the decoded dump, rendered as `-j` prints it, equals the readback's `info_data`: every key, no extra |
+| positive: several options | `add_several` | stp_state 1, priority 100, vlan_filtering 1, mcast_snooping 0; `bridge_id` priority `0064` |
+| positive: the boolopts | `add_boolopts` | `BoolOpts` with mst_enabled, mdb_offload_fail_notification and fdb_local_vlan_0 set |
+| positive: 802.1ad | `add_vlan_protocol` | vlan_protocol 0x88a8 |
+| negative: a nil nest | `nil` | `nil`, as `ParseBondInfoData` does |
+| negative: a u32 attribute of 2 bytes | built `IFLA_BR_FORWARD_DELAY` | absent, not a short read |
+| boundary: an empty nest | `[]byte{}` | a `BridgeInfo` with nothing present |
+| boundary: the highest id | built `IFLA_BR_STP_MODE` 2 | stp_mode kernel |
+| corner: vlan_protocol is big-endian | built `81 00` | 0x8100, not 0x0081 |
+| corner: an id past `IFLA_BR_STP_MODE` | built type 51, then `IFLA_BR_STP_STATE` | `Unknown` is [51], stp_state 1 |
+| corner: a truncated nest keeps what came before the cut | the first 50 bytes of `add_default`'s blob: four 12-byte timers, then half of `forward_delay` | the timers present, forward_delay absent |
+| corner: a querier state nest | `add_mcast_querier`'s dump | addresses `0.0.0.0` and `::`, no port, as the readback prints them |
+
+`TestEncodeBridgeInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | the settings of the 55 rows that sent one (50 at 0, 5 the kernel refused), from the table in [KC2-T01](#kc2-t01-the-kind-corpus-and-bridge); a row that sent one and is not listed, or the reverse, fails | `IFLA_INFO_DATA` byte-identical to the one in the row's `ip.pcap`; `add_default`'s is empty, as its request has no data nest |
+| positive: a bare `type bridge` | no settings | no attributes (goip leaves `LinkWrite.HasData` false) |
+| negative: a setting with no option row | a nil `Spec` | `ErrBridgeSettingWire` |
+| negative: a read-only option | `bridge_id` | `ErrBridgeSettingWire` |
+| negative: a value too wide for its wire | priority 65536 | `ErrBridgeSettingRange` |
+| boundary: `fdb_flush` | the flag | a 4-byte attribute, no payload |
+| boundary: a u64 takes its full width | `mcast_query_interval` 2^63 | 8 bytes, no range error |
+| corner: the boolopt goes last | `mst_enabled 1 priority 100` | `IFLA_BR_PRIORITY`, then `IFLA_BR_MULTI_BOOLOPT` |
+| corner: a later boolopt word wins | `mst_enabled 1 mst_enabled 0` | optval 0, optmask 4 |
+| corner: vlan_protocol in network order | 0x88a8 | payload `88 a8` |
+
+**Mutation check:** vlan_protocol read little-endian (the 802.1ad row), the boolopt placed in argument order (its corner), `stp_mode` dropped from `BridgeOptions` (the every-row row).
+
+#### KP1-T02 The bridge_slave parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_bridge_slave.go`, in KP1-T01's shape, reusing `BridgeOptionSpec`, `BridgeValue` and `putBridgeSetting`:
+- **`BridgeSlaveOptions`:** 44 rows. 36 are the `IFLA_BRPORT_*` attributes `bridge_slave_print_opt` prints, in its order (`ip/iplink_bridge_slave.c`). Then come `mcast_fast_leave` (a second keyword for `IFLA_BRPORT_FAST_LEAVE`, with no `-j` key: `fastleave` prints it), `fdb_flush` (write-only), and six read-only rows with no keyword for the attributes the kernel dumps and `ip` never prints (the MRP and EHT counters, `mcast_n_groups`, `mcast_max_groups`), so they decode rather than land in `Unknown`. `neigh_vlan_suppress`, `neigh_forward_grat`, `mab` and `backup_nhid` are `strcmp`; the rest are `matches`.
+- **The wires:** T01's u8, u16, u32, flag, `ifla_bridge_id` and timer wires, plus two new ones, both added to T01's switches:
+  - `BridgeWireOnOff`: the 19 on/off words, a u8 each through `bridge_slave_parse_on_off`, printed as a bool by `-j`. `root_block` is `IFLA_BRPORT_PROTECT`, `fastleave` and `mcast_fast_leave` are `IFLA_BRPORT_FAST_LEAVE`, and `flood` is `IFLA_BRPORT_UNICAST_FLOOD`.
+  - `BridgeWireIfindex`: `backup_port`, a u32 ifindex that `ip` prints as a name; `nobackup_port` sends 0.
+  - `BridgeOptionSpec.Hex` marks the two `group_fwd_mask`s, which print in hex.
+- **`IflaBrportNeighForwardGrat`** = 45. x/sys/unix v0.49 stops at `IFLA_BRPORT_BACKUP_NHID` (44). `BridgePortStates` are `state`'s names; past `blocking` (4), `-j` prints `state_index` instead.
+- **The decoder:** `BridgeSlaveInfo` (an array indexed by id, `BridgeID`, `RootID`, `Unknown`), `ParseBridgeSlaveData(nest []byte) *BridgeSlaveInfo`, a `LinkInfo.BridgeSlave` field, and a `setLinkInfoNest` branch on `SlaveKind`. The field moves the replay goldens' digests again, regenerated as in T01.
+- **The encoder:** `EncodeBridgeSlaveData(settings []BridgeSetting) ([]byte, error)`, settings in argument order.
+- **The benchmark:** a `BenchmarkParseBridgeSlaveData` over `set_several`'s blob.
+- **The test harness:** T01's helpers become `kindRows{kind, nest, key, opts}`, shared by both kinds: a row's request, dump, name lookups (an ifindex resolved through the readback's own answers), `-d -j` object and argument parsing.
+
+The corpus is 42 rows: 30 at rc 0, 7 the kernel refused (rc 2, a request sent), and 5 `ip` refused before sending (rc 255 or 1: `set_backup_port_missing`, `set_cost_bad`, `set_no_value`, `set_on_off_bad`, `set_strcmp_abbrev`), which have no encoder row; KG1 replays them.
+
+`TestBridgeSlaveDumpMatchesReadback`: a subtest per rc 0 row (30), the decoded dump in `netlink_route_getlink_detail_json.pcap`, rendered as `-j` prints it, equals the readback's `info_slave_data`: every key, no extra.
+
+`TestParseBridgeSlaveData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: a port's dump | `set_several`'s answer for `p0` | cost 10, priority 7, learning false, flood true, the `-d -j` readback's values |
+| positive: the 7.2.0 attribute | `set_neigh_forward_grat` | neigh_forward_grat true |
+| positive: a backup port is p1's ifindex | `set_backup_port`, no names | backup_port 5 |
+| positive: a backup port resolves to p1 | `set_backup_port`, with the readback's name lookups | backup_port `p1` |
+| negative: a nil nest | `nil` | `nil` |
+| negative: a u8 attribute of no bytes | built `IFLA_BRPORT_STATE`, empty | neither state nor state_index |
+| boundary: an empty nest | `[]byte{}` | a `BridgeSlaveInfo` with nothing present |
+| boundary: the highest id | built `IFLA_BRPORT_NEIGH_FORWARD_GRAT` 1 | neigh_forward_grat true |
+| corner: the port id and number | `set_several`'s `IFLA_BRPORT_ID` and `IFLA_BRPORT_NO` | `0x1c01` and `0x1` |
+| corner: an id past `IFLA_BRPORT_NEIGH_FORWARD_GRAT` is listed and the rest decoded | built type 46, then `IFLA_BRPORT_GUARD` 1 | `Unknown` is [46], guard true |
+| corner: a truncated nest keeps what came before the cut | `set_several`'s first 10 bytes: state's 8, then half of priority | state disabled, priority absent |
+| corner: a state past blocking is its index | built `IFLA_BRPORT_STATE` 5 | state absent, state_index 5 |
+
+`TestEncodeBridgeSlaveData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | the settings of the 37 rows that sent one (30 at 0, 7 the kernel refused), from SLAVE_OPTIONS in `kind-write-corpus.exp`; a row that sent one and is not listed, or the reverse, fails | `IFLA_INFO_SLAVE_DATA` byte-identical to the one in the row's `ip.pcap` |
+| positive: several in argument order | `cost 10 priority 7 learning off` | `IFLA_BRPORT_COST`, `IFLA_BRPORT_PRIORITY`, `IFLA_BRPORT_LEARNING` in that order |
+| negative: a value too wide for its wire | state 256 | `ErrBridgeSettingRange` |
+| negative: a read-only option | `port_id` | `ErrBridgeSettingWire` |
+| negative: a bridge boolopt in a port write | the bridge's `mst_enabled 1` | `ErrBridgeSettingWire` |
+| boundary: nobackup_port is backup_port 0 | backup_port 0 | a u32 0 |
+| boundary: fdb_flush is a bare header | the flag | `04 00 18 00`, no payload |
+| corner: two keywords, one attribute | `fastleave on mcast_fast_leave off` | two `IFLA_BRPORT_FAST_LEAVE` attributes, 1 then 0 |
+
+`TestLinkInfoBridgeKinds`, whole answers through `ParseNewLink`, so each branch is keyed on the right kind:
+
+| description | input | expected |
+|---|---|---|
+| positive: a port decodes BridgeSlave | `bridge_slave/set_several`'s `-d` readback | `BridgeSlave` cost 10, `Bridge` nil |
+| positive: a bridge decodes Bridge | `bridge/add_default`'s | `Bridge` forward_delay 1500, `BridgeSlave` nil |
+| negative: a dummy that is no port decodes neither | `bridge_slave/set_not_enslaved`'s | both nil |
+| corner: a vrf port's slave data is not a bridge port's | `vrf_slave/set_master`'s | both nil |
+
+**Mutation check:** `flood` mapped to `IFLA_BRPORT_MCAST_FLOOD` (the every-row rows and the port's dump), `IflaBrportNeighForwardGrat` off by one (every row whose dump carries it), the `SlaveKind` branch keyed on `Kind` (`TestLinkInfoBridgeKinds`' port row and `TestParseNewLinkRealFixture`).
+
+### KP2 — VLAN family parsers
+
+Three tasks, one per parser file, matching KC3's: KP2-T01 vlan, KP2-T02 macvlan and macvtap (one codec, two kinds), KP2-T03 ipvlan and ipvtap (likewise), which closes KP2. The source is the KC3 rows in `tdLinkWrite_7_3_0 + "/kinds/<kind>"`, read through KP1-T02's `kindRows` harness. Readback agreement is against `netlink_route_getlink_detail_json.pcap`, as in KP1.
+
+**Shape.** These kinds have 2 to 15 attributes, an enum mode and a flags word, so each gets a typed `<Kind>Info` struct rather than a `BridgeOptionSpec` table, and an encoder over `<Kind>Setting`s in argument order. Each `iplink_*.c` adds some attributes inside its argument loop and some after it; the encoder reproduces that split, and a corner row pins it. Each kind adds a `LinkInfo` field and a `setLinkInfoNest` branch on `Kind`, regenerating the replay goldens' digests (the decision log). A macvtap or ipvtap device decodes into the same field as its sibling, since the kernel dumps the same attributes.
+
+**Counts.** A row that sent a request is one at rc 0 or rc 2; `ip`'s refusals (rc 1 and 255) send none and have no encoder row.
+
+| kind | rows | rc 0 | rc 2 | `ip` refused |
+|---|---|---|---|---|
+| vlan | 28 | 15 | 6 | 7 |
+| macvlan | 34 | 20 | 5 | 9 |
+| macvtap | 6 | 5 | 0 | 1 |
+| ipvlan | 18 | 11 | 3 | 4 |
+| ipvtap | 4 | 3 | 0 | 1 |
+
+#### KP2-T01 The vlan parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_vlan.go`:
+- **`VlanInfo`:** `ID` (u16), `Protocol` (u16, big-endian on the wire, as the bridge's `vlan_protocol`), `Flags` and `Mask` (`struct ifla_vlan_flags`, u32 each), and `Ingress`, `Egress []VlanQosMapping` (`struct ifla_vlan_qos_mapping`, `from` and `to` u32, under `IFLA_VLAN_QOS_MAPPING` in the two nests). Present bits for each.
+- **`ParseVlanInfoData(nest []byte) *VlanInfo`**, `LinkInfo.Vlan`, and the branch.
+- **`EncodeVlanInfoData(settings []VlanSetting) ([]byte, error)`:** `protocol`, `id` and the two qos maps go in argument order (`vlan_parse_opt` adds them in its loop); the five flag words fold into one `IFLA_VLAN_FLAGS`, added after the loop only when the mask is set, so it goes last. A qos map opens its nest before its first pair, as `vlan_parse_qos_map` does. The errors, `ErrKindSettingOption` and `ErrKindSettingRange`, are shared with KP2's later kinds.
+- **`VlanFlags`:** keyword, printed name and bit, in `vlan_print_flags`' order, which is not bit order: `MVRP` (0x8) prints before `LOOSE_BINDING` (0x4).
+- **The render oracle:** `vlan_print_opt` prints `protocol` through `ll_proto_n2a` (`802.1Q`, `802.1ad`), `id`, `flags` as the names of `Flags`' set bits (`REORDER_HDR` … `BRIDGE_BINDING`, then any leftover in hex), and `ingress_qos`/`egress_qos` as `{from, to}` lists. It prints nothing when `IFLA_VLAN_ID` is missing or short.
+- **The benchmark:** `BenchmarkParseVlanInfoData` over `add_ingress_qos_map`'s blob.
+
+`TestVlanDumpMatchesReadback`: a subtest per rc 0 row (15); the decoded dump, rendered as `-j` prints it, equals the readback's `info_data`, every key and no extra.
+
+`TestParseVlanInfoData`:

+| negative: an id too wide | 65536 | `ErrKindSettingRange` |
+| negative: a setting with no option | the zero option | `ErrKindSettingOption` |

+#### KP2-T02 The macvlan and macvtap parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_macvlan.go`:
+- **`MacvlanInfo`:** `Mode` (u32: private 1, vepa 2, bridge 4, passthru 8, source 16), `Flags` (u16: nopromisc 1, nodst 2), `BcQueueLen` and `BcQueueLenUsed` (u32), `BcCutoff` (s32), `MacaddrCount` (u32), `Macaddrs` (the 6-byte `IFLA_MACVLAN_MACADDR`s under `IFLA_MACVLAN_MACADDR_DATA`, in dump order), with present bits.
+- **`ParseMacvlanInfoData`**, `LinkInfo.Macvlan`, a branch for `macvlan` and `macvtap`.
+- **`EncodeMacvlanInfoData`:** `macaddr` (its `MACADDR_MODE`: add 0, del 1, flush 2, set 3; then a `MACADDR` for add and del, or a `MACADDR_DATA` nest for set), `bcqueuelen` and `bclim` in argument order; then `IFLA_MACVLAN_MODE` if a mode was given (the last wins), then `IFLA_MACVLAN_FLAGS` if any flag word was (a `flag null` sends 0). nopromisc outside passthru is `ErrMacvlanNopromisc`, `ip`'s own refusal. The kernel never dumps `MACADDR_MODE` or a top-level `MACADDR`; the decoder skips them without listing them as unknown.
+- **The render oracle:** `macvlan_print_opt` prints nothing without a mode; `nopromisc` and `nodst` as `true` when set; `bcqueuelen`, `usedbcqueuelen` and `bclim`; and, in source mode only, `macaddr_count` and `macaddr_data`.

+- **`ParseIpvlanInfoData`**, `LinkInfo.Ipvlan`, a branch for `ipvlan` and `ipvtap`.

+
+### KP3 — UDP overlay parsers
+
+Four tasks, one per KC4 task: KP3-T01 vxlan, KP3-T02 geneve, KP3-T03 bareudp and amt, KP3-T04 gtp, which closes KP3. KP2's shape carries over: a typed `<Kind>Info` with present bits, a `LinkInfo` field and a `setLinkInfoNest` branch on `Kind`, the replay goldens regenerated, a `<Kind>Setting` encoder, and the `kindRows` harness against `netlink_route_getlink_detail_json.pcap`.
+
+**What these kinds add to KP2's shape:**
+- **The encoder needs the operation.** vxlan and geneve send some attributes only on an add (vxlan's `LEARNING`; geneve's `LABEL`, `TTL` and `TOS`), and gtp always sends `CREATE_SOCKETS`. Their encoders take `Encode<Kind>InfoData(settings []<Kind>Setting, set bool)`, and the corpus rows' slugs (`set_*`) say which.
+- **Several attributes go after the loop in a fixed order,** whatever the words' order: vxlan's `ID`, `LOCAL`/`LOCAL6`, `GROUP`/`GROUP6`, `LEARNING`, `PORT`; geneve's `ID`, `REMOTE`/`REMOTE6`, `LOCAL`/`LOCAL6`, `LABEL`, `TTL`, `TOS`, `PORT`, `COLLECT_METADATA`, `INNER_PROTO_INHERIT` and the checksum flags. Each task's corner rows pin the split.
+- **Big-endian fields:** the UDP ports (vxlan `PORT` and `PORT_RANGE`, geneve `PORT`, bareudp `PORT` and `ETHERTYPE`, amt's two ports), the labels (`htonl`), vxlan's `RESERVED_BITS` (a `__be64`), and every IPv4 address. `srcportmin` is host order.
+- **Name lookups:** vxlan's and amt's `LINK` print through `ll_index_to_name`, resolved from the readback's own answers as bridge_slave's `backup_port` is.
+- **Flag attributes:** vxlan's `GBP` and `GPE`, geneve's `COLLECT_METADATA` and `INNER_PROTO_INHERIT`, and bareudp's `MULTIPROTO_MODE` have no payload (gtp's `CREATE_SOCKETS` is a u8 1); vxlan's `TTL_INHERIT` is likewise empty on the request and a u8 in the dump.
+
+**Counts.**
+

+| amt | 20 | 5 | 8 | 7 | 13 |
+| gtp | 19 | 7 | 4 | 8 | 11 |
+
+#### KP3-T01 The vxlan parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_vxlan.go`:
+- **`VxlanInfo`:** the id; `Group`, `Local` as `netip.Addr` (`GROUP` or, when it is absent, `GROUP6`, as `vxlan_print_opt` reads them; likewise `LOCAL`/`LOCAL6`); the lower's ifindex; `TTL`, `TTLInherit`, `TOS`, `DF`, `Label` (host order), `Aging`, `Limit`, and the unprinted `LabelPolicy`; the source port range (two big-endian u16s) and the destination port; `ReservedBits` (big-endian u64); the 14 u8 booleans of `vxlan_print_opt`'s `vxlan_opts` table, by index; and the flags `GBP`, `GPE` and `RemcsumNopartial`. Each value has a present bit. `IFLA_VXLAN_AGEING`, `RESERVED_BITS` and `MC_ROUTE` are package constants (`IflaVxlanAgeing`, `IflaVxlanReservedBits`, `IflaVxlanMcRoute`): x/sys v0.49.0 lacks the last two, and misspell reads the first.
+- **`VxlanBoolOptions`:** the table, in print order (`external`, `vnifilter`, `learning`, `proxy`, `rsc`, `l2miss`, `l3miss`, `udp_csum`, `udp_zero_csum6_tx`, `udp_zero_csum6_rx`, `remcsum_tx`, `remcsum_rx`, `localbypass`, `mcroute`), with their ids.
+- **`EncodeVxlanInfoData(settings, set)`:** `LINK`, `TTL`/`TTL_INHERIT`, `TOS`, `DF`, `LABEL`, `AGEING`, `LIMIT`, `PORT_RANGE` (only when either end is nonzero), the u8 flags, `RESERVED_BITS`, `COLLECT_METADATA`, `GBP`, `GPE`, `VNIFILTER` and `MC_ROUTE` in argument order; then `ID` if given, the local, the group or remote, `LEARNING` (on an add always, 0 after `external` or `nolearning`; on a set only when a learning word was given), and `PORT` when nonzero (4790 for `gpe` without `dstport`). No settings encode to nothing, as for ipvlan. It refuses what `vxlan_parse_opt` refuses with `ErrKindSettingConflict` (group and remote, a local of the other family, vnifilter without external, external with an id, no id on an add, a group without dev) and a value out of range, or an address of the wrong cast, with `ErrKindSettingRange`.
+- **The render oracle:** `vxlan_print_opt`: `group` or `remote` by whether the address is multicast, `local`, `link` by name, `port_range` as `{low, high}`, `port`, `tos` (hex, absent at 0), `ttl` (absent under `ttl_inherit`; JSON prints 0), `df` (`unset` is JSON-only), `label` (hex, absent at 0), `ageing`, `limit` (absent at 0), `reserved_bits` (hex), `gbp` and `gpe` as JSON null, and each bool option the dump carries.

+
+#### KP3-T02 The geneve parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_geneve.go`:
+- **`GeneveInfo`:** the id; `Remote` and `Local` as `netip.Addr` (`REMOTE` over `REMOTE6`, `LOCAL` over `LOCAL6`, as `geneve_print_opt` reads them); `TTL`, `TTLInherit`, `TOS`, `DF`, `Label` (host order), the port; the unprinted `PORT_RANGE` the kernel dumps on every device; `CollectMetadata`, `InnerProtoInherit` and `GroHint` (flags); the three checksum u8s; present bits. `PORT_RANGE`, `GRO_HINT`, `LOCAL` and `LOCAL6` (15 to 18) are package constants, absent from x/sys v0.49.0.
+- **`EncodeGeneveInfoData(settings, set)`:** `TTL_INHERIT` (from `ttl inherit`) and `DF` go in argument order, inside the loop. The rest goes after it, in `geneve_parse_opt`'s order: `ID` always (0 for `external`), the remote, the local (7.2.0's `local`, `LOCAL` or `LOCAL6` by family), `LABEL`, `TTL` and `TOS` on an add or when given (`ttl inherit` and `ttl auto` give `TTL` 0), `PORT` when nonzero, `COLLECT_METADATA`, `INNER_PROTO_INHERIT`, then each checksum word given. A later checksum word overrides an earlier one (`ip` refuses the pair as a duplicate first). It refuses external with an id with `ErrKindSettingConflict`, and no id without external or an add with no remote and no external with `ErrKindSettingMissing`.
+- **Shared with vxlan:** the tolerant reads and range-checked writes (`kindU32`, `kindPutAddr`, `kindBE` and the rest) and `ErrKindSettingConflict` and `ErrKindSettingMissing` live in `xtcpnl_kind_wire.go`, for KP3-T03 and KP3-T04 too.
+- **The render oracle:** `geneve_print_opt`: `external` as true when the flag is present, `id`, `remote`/`remote6` and `local`/`local6` by family, `ttl` (absent under `ttl_inherit`), `tos` and `label` in hex, `df`, `port`, the checksum bools (JSON always prints them), and `inner_proto_inherit`.

A word given twice (`multiproto` and `nomultiproto` count as one) is `ErrKindSettingConflict`; no `dstport` or `ethertype` is `ErrKindSettingMissing`. The render prints `ethertype` through `ll_proto_n2a` (`mpls_uc`, `ip`, or the number in brackets, `[4660]`), and `multiproto` as true or false.
+- **amt:** `AmtInfo` (mode u32, `gateway` 0 or `relay` 1; the two ports, big-endian; local, remote and discovery IPv4 addresses; the lower's ifindex; `max_tunnels`); `EncodeAmtInfoData` in argument order, a repeated `mode` sent twice, a second `local` or `discovery` `ErrKindSettingConflict`. The render prints the lower by name. The IDs (1 to 8) are package constants, absent from x/sys v0.49.0.

+
+#### KP3-T04 The gtp parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_gtp.go`: `GtpInfo` (role u32, `ggsn` 0 or `sgsn` 1; `PDP_HASHSIZE` u32; `RESTART_COUNT` u8; the request-only `FD0`, `FD1`, `CREATE_SOCKETS`, `LOCAL` and `LOCAL6` skipped without being listed), and `EncodeGtpInfoData(settings)`: `CREATE_SOCKETS` (a u8 1) first whenever there is a setting, then the words in argument order, then `PDP_HASHSIZE` 1024 when no `hsize` was given. An unknown word is the caller's to skip, as `ip` skips it. A word given twice is `ErrKindSettingConflict` and no role `ErrKindSettingMissing`, as `check_duparg` and the missing-role check refuse them. The benchmark parses `add_restart_count`'s blob.
+
+`TestGtpDumpMatchesReadback` (7 rows), then:
+
+| description | input | expected |
+|---|---|---|
+| positive: a ggsn's dump | `add_ggsn` | role `ggsn`, hsize 1024 |

+
+**Mutation check:** the default hash size dropped (`add_ggsn`'s request), the roles swapped (`add_sgsn`), `CREATE_SOCKETS` omitted (every request). It closes KP3.
+
+### KP4 — IP tunnel parsers
+
+Five tasks, one per KC5 task and iproute2 parser: KP4-T01 gre, gretap and erspan (`link_gre.c`); KP4-T02 ip6gre, ip6gretap and ip6erspan (`link_gre6.c`); KP4-T03 ipip and sit (`link_iptnl.c`); KP4-T04 ip6tnl (`link_ip6tnl.c`); KP4-T05 vti, vti6 and xfrm (`link_vti.c`, `link_vti6.c`, `link_xfrm.c`), which closes KP4. KP3's shape carries over: a typed `<Kind>Info` with present bits, a `LinkInfo` field and a `setLinkInfoNest` branch, the replay goldens regenerated, a `<Kind>Setting` encoder, and the `kindRows` harness.
+
+**What these kinds add to KP3's shape:**
+- **A set's request starts from the device.** Every parser here but xfrm's sends an `RTM_GETLINK` on a set and seeds its variables from the reply's `INFO_DATA` before it reads the words, then sends the full attribute set. So the encoders take the device's decoded state instead of a bool: `Encode<Kind>InfoData(settings []<Kind>Setting, cur *<Kind>Info)`, with `cur` nil on an add. The corpus has the reply: a set row's `ip.pcap` holds the prefetch's `RTM_NEWLINK` answer ahead of the request, so the tests decode it with the task's own parser and pass it in.
+- **The prefetch's port bug.** gre, gre6, iptnl and ip6tnl read `ENCAP_SPORT`/`ENCAP_DPORT` with `rta_getattr_u16` and send them back through `htons`, so on a little-endian host a port the set didn't name is re-sent byte-swapped. ip6tnl doesn't seed the encap at all and resets it. The encoders copy each behavior; `ip6gre/set_encap_sport_swap` pins the first.
+- **Two shared attribute spaces.** `IFLA_GRE_*` serves both gre files and `IFLA_IPTUN_*` serves iptnl and ip6tnl, with 4- or 16-byte addresses. One `GreInfo` and one `IptunInfo` decode each space for every kind that uses it, with `Local` and `Remote` as `netip.Addr`; each file gets its own encoder and its own render oracle in the test.
+- **The encap block** (`ENCAP_TYPE`, `ENCAP_FLAGS`, and the big-endian `ENCAP_SPORT` and `ENCAP_DPORT`) is common to gre, gre6, iptnl and ip6tnl at different ids, and `tnl_print_encap` prints it the same way: no `encap` key for type 0, a `type` of `fou`, `gue` or null. A `TunnelEncap` struct and its helpers live in `xtcpnl_kind_wire.go`, and KP4-T01 adds them.
+- **Keys print dotted.** `IKEY`/`OKEY` are big-endian u32s that `ip` prints through `inet_ntop(AF_INET)` (`0.0.0.42`), only when the matching `GRE_KEY` flag is set (gre) or the key is nonzero (vti). The `GRE_*` flags are big-endian u16 bits: `CSUM` 0x8000, `KEY` 0x2000, `SEQ` 0x1000.
+- **Endpoints always print.** `tnl_print_endpoint` prints `remote` and `local` on every device: `any` for an absent or zero address, `unknown` for the wrong length.
+- **The kernel adds bits `ip` never sent.** ip6gre's and ip6tnl's `FLAGS` carry `IP6_TNL_F_CAP_*` (0x10000 to 0x40000), which a set's prefetch sends back; erspan's dumped `OFLAGS` gains `KEY`. The decoders keep the values whole.
+
+**Counts.**
+
+| kind | rows | rc 0 | rc 2 | `ip` refused | requests |
+|---|---|---|---|---|---|
+| gre | 45 | 24 | 7 | 14 | 31 |

+| xfrm | 23 | 9 | 8 | 6 | 17 |
+
+"requests" counts the rows at rc 0 or 2; a bare `type <kind>` sends no `INFO_DATA`, and its row expects none.
+
+#### KP4-T01 The gre, gretap and erspan parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_gre.go`, plus the `TunnelEncap` helpers in `xtcpnl_kind_wire.go`:
+- **`GreInfo`:** every `IFLA_GRE_*` (1 to 24): `Link`, `IFlags`/`OFlags` (host-order values of the big-endian bits), `IKey`/`OKey` (the wire's four bytes as a big-endian u32), `Local`/`Remote` (4 or 16 bytes), `TTL`, `TOS`, `PMTUDisc`, the IPv6-only `EncapLimit`, `FlowInfo` and `Flags`, the `TunnelEncap`, `CollectMetadata`, `IgnoreDF`, `FwMark`, and the four erspan attributes; present bits. `LinkInfo.Gre` is set for all six gre kinds.
+- **`EncodeGreInfoData(settings, cur)`:** `gre_parse_opt` for gre, gretap and erspan (an erspan flag in the call says which). A multicast remote fills a zero `IKEY`/`OKEY` with the group and sets `KEY`, and needs a local. `external` sends `COLLECT_METADATA` alone. Otherwise, in order: `IKEY`, `OKEY`, `IFLAGS`, `OFLAGS`, `LOCAL` and `REMOTE` when nonzero, `PMTUDISC` (1 by default), `IGNORE_DF` when given (`noignore-df` sends 0), `TOS`, `LINK` when nonzero, `TTL`, `FWMARK`; for erspan `ERSPAN_VER` (1 by default), then `ERSPAN_INDEX` (version 1, nonzero index) or `ERSPAN_DIR` and `ERSPAN_HWID` (version 2); then the four `ENCAP_*`. `cur` seeds every value first, ports byte-swapped, `IGNORE_DF` as `!!`, and its `COLLECT_METADATA` forces the metadata path. A repeated word overwrites. Refusals: the multicast remote without a local (`ErrKindSettingMissing`), an erspan index outside 1 to 2^20-1, a version past 2, a tos past 0xff (`ErrKindSettingRange`).
+- **The render oracle:** `gre_print_opt`: `external`; `remote`/`local` always; `link` by name; `ttl` always; `tos` as `%#llx` when nonzero; `pmtudisc` as a bool; `ignore_df` when on; `ikey`/`okey` dotted under the `KEY` flag; `iseq`, `oseq`, `icsum`, `ocsum`; `fwmark` when nonzero; `erspan_index`, `erspan_ver`, `erspan_dir` (`ingress`/`egress`), `erspan_hwid` (`%#llx`, so 0 is `"0"`); and the `encap` object.
+- **The benchmark:** `BenchmarkParseGreInfoData` over `erspan/add_ver2`'s blob.
+
+`TestGreDumpMatchesReadback`: a subtest per rc 0 row of gre, gretap and erspan (44).

+
+`TestLinkInfoGreKinds`: gre, gretap and erspan decode `Gre` (positive ×2, corner: erspan); a vti does not (negative).
+
+**Mutation check:** the `GRE_KEY` bit read little-endian (`add_key`); the prefetched port not swapped (the built corner row: gre has no corpus row for it); erspan's index sent at version 2 (`add_ver2`).
+
+#### KP4-T02 The ip6gre, ip6gretap and ip6erspan parser
+
+**Code.** `xtcpnl_gre6.go`, on KP4-T01's `GreInfo`:
+- **`EncodeGre6InfoData(settings, cur)`:** `link_gre6.c`'s `gre_parse_opt`, on KP4-T01's `GreSetting` with four more options (`EncapLimit`, `TClass`, `FlowLabel`, and `TnlFlag` for the `IP6_TNL_F_*` words); gre's `pmtudisc`, `ignore-df` and `tos` settings are refused (`ErrKindSettingOption`), as is an IPv4 address (`ErrKindSettingRange`). `external` sends `COLLECT_METADATA` alone. Otherwise, in order: `IKEY`, `OKEY`, `IFLAGS`, `OFLAGS`, `LOCAL` and `REMOTE` when set and not `::`, `LINK` when nonzero, `TTL` (64 by default), `ENCAP_LIMIT` (4), `FLOWINFO`, `FLAGS`, `FWMARK`, `ERSPAN_VER` (1, sent for all three kinds), `ERSPAN_INDEX` or `ERSPAN_DIR` and `ERSPAN_HWID` as gre's, then the four `ENCAP_*` (`ENCAP_FLAGS` `CSUM6` by default). The `IP6_TNL_F_*` words: `encaplimit none` (0x1, the limit still sent), `tclass inherit` (0x2), `flowlabel inherit` (0x4), `dscp inherit` (0x10), `fwmark inherit` (0x20, fwmark 0), `[no]allow-localremote` (0x40). `tclass` (hex) and `flowlabel` (hex, ≤0xfffff) clear their bits in `FLOWINFO` and set them. `cur` seeds every value, `FLAGS` with its `CAP` bits and the ports swapped.
+- **The render oracle:** `link_gre6.c`'s `gre_print_opt`: `external`, `remote`, `local`, `link`, `ttl`, `ip6_tnl_f_ign_encap_limit` or `encap_limit`, `ip6_tnl_f_use_orig_tclass` or `tclass` (`0x%02x`), `ip6_tnl_f_use_orig_flowlabel` or `flowlabel` (`0x%05x`), `ip6_tnl_f_rcv_dscp_copy`, the keys and seq/csum flags, `ip6_tnl_f_allow_local_remote`, `ip6_tnl_f_use_orig_fwmark` or `fwmark`, the erspan keys, `encap`.
+- **The benchmark:** `BenchmarkParseGre6InfoData` over `ip6erspan/add_v2`'s blob.
+

+
+`TestParseGre6InfoData`:

+
+#### KP4-T03 The ipip and sit parser
+
+**Code.** A new `pkg/xtcpnl/xtcpnl_iptun.go`:
+- **`IptunInfo`:** every `IFLA_IPTUN_*` (1 to 20): `Link`, `Local`/`Remote` (4 or 16 bytes), `TTL`, `TOS`, `EncapLimit`, `FlowInfo`, `Flags` (u16 for sit's `ISATAP`, u32 for ip6tnl's), `Proto`, `PMTUDisc`, the four 6rd attributes, the `TunnelEncap`, `CollectMetadata`, `FwMark`; present bits. `LinkInfo.Iptun` is set for ipip, sit and ip6tnl.
+- **`EncodeIptunInfoData(settings, cur, sit bool)`:** `iptunnel_parse_opt`. It refuses `ttl` nonzero with `nopmtudisc`, seeded values included (`ErrKindSettingConflict`). `PROTO` goes first (0 by default for both kinds); `external` then sends `COLLECT_METADATA` alone. Otherwise: `LOCAL` and `REMOTE` when nonzero, `PMTUDISC` (1), `TOS`, `TTL`, `LINK`, `FWMARK`, the four `ENCAP_*`; for sit `FLAGS`, then `6RD_PREFIX` and `6RD_PREFIXLEN` when a prefix is set, and `6RD_RELAY_PREFIX` and `6RD_RELAY_PREFIXLEN` likewise. ipip parses the 6rd words and sends nothing for them. Mode words: `ip6ip` (41) is sit's only. `isatap` is sit's. `cur` seeds every value, sit's 6rd attributes and `ISATAP` included, the ports swapped. `6rd-reset` has no setting: it crashes `ip` 7.2.0 (decision log), and KG5 decides what goip does.
+- **The render oracle:** `iptunnel_print_opt`: `external`, `proto` (`ipip`, `ip6ip`, `mplsip`, `any`), `remote`, `local`, `link`, `ttl`, `tos` (`%#llx`, nonzero), `pmtudisc` always, `isatap`, `prefix`/`prefixlen`/`relay_prefix`/`relay_prefixlen` when the prefix length is nonzero, `fwmark`, `encap`.

Otherwise: `LOCAL` and `REMOTE` when set, `TTL` (64), `ENCAP_LIMIT` (4), `FLOWINFO`, `FLAGS`, `LINK`, `FWMARK`, then the four `ENCAP_*`. The flag words as KP4-T02's. `cur` seeds the endpoints, ttl, encap limit, flow info, `FLAGS` with its `CAP` bits, link, proto, metadata and fwmark, but **not** the encap: a set resets it to type 0, `CSUM6`, ports 0. Mode words: `ip6ip6` 41, `ipip6` 4, `any` 0.
+- **The render oracle:** `ip6tunnel_print_opt`: `external`, `proto` (`ip6ip6`, `ipip6`, `any`), `remote`, `local`, `link`, `ttl`, the encap-limit, tclass, flowlabel, dscp, mip6, allow-local-remote and fwmark pairs as KP4-T02's, `encap`.

+
+#### KP4-T05 The vti, vti6 and xfrm parsers
+
+**Code.** `xtcpnl_vti.go` and `xtcpnl_xfrm_link.go` (`xtcpnl_xfrm.go` is the NETLINK_XFRM family's, so the interface kind's names carry `Link`):
+- **`VtiInfo`:** `Link`, `IKey`/`OKey` (big-endian), `Local`/`Remote` (4 or 16 bytes), `FwMark`. `LinkInfo.Vti` for vti and vti6.
+- **`EncodeVtiInfoData(settings, cur, v6)`:** vti's and vti6's `parse_opt`, the same apart from the family, which `v6` names: `IKEY`, `OKEY` always, `LOCAL` and `REMOTE` when set and nonzero, `FWMARK` always, `LINK` when nonzero. `cur` seeds the endpoints, keys and fwmark, and the link through `rta_getattr_u8`: only its low byte, so a lower at ifindex 256 is re-sent as 0, and not at all. The encoder copies it; a decision-log entry records it, and nothing goes upstream. An endpoint of the other family is `ErrKindSettingRange`.
+- **`XfrmLinkInfo`:** `Link`, `IfID`, `External`. `LinkInfo.Xfrm`.
+- **`EncodeXfrmLinkInfoData(settings)`:** no prefetch. `IF_ID` goes inside the loop, once per `if_id` word, and an `if_id` of 0 is `ErrKindSettingRange`; after it, `external` sends `COLLECT_METADATA` and refuses an earlier `if_id` or `dev` (`ErrKindSettingConflict`), and otherwise no `if_id` is `ErrKindSettingMissing` and `LINK` follows when nonzero.
+- **The render oracles:** vti and vti6: `remote`, `local`, `link`, `ikey`/`okey` dotted when nonzero, `fwmark` when nonzero. xfrm: `external` true and nothing else, or `if_id` as `%#llx`; `link` is never printed.

+
+`TestLinkInfoTunnelKinds`: vti and vti6 decode `Vti`, xfrm `Xfrm`; a gre decodes neither.
+
+**Mutation check:** the vti `LINK` seeded whole (the low-byte corner row); xfrm's `IF_ID` held to after the loop (`add_if_id_twice`); vti's `REMOTE` sent when unset or zero (the `remote any` rows). It closes KP4.
+
+### KP5 — The remaining kinds' parsers
+
+Four tasks, one per KC6 task: KP5-T01 hsr (`iplink_hsr.c`); KP5-T02 netkit (`iplink_netkit.c`); KP5-T03 vrf, vrf_slave and vxcan (`iplink_vrf.c`, `iplink_vxcan.c`); KP5-T04 batadv and the five kinds `ip` has no parser for (`iplink_batadv.c`, `iplink_ifb.c`, `iplink_nlmon.c`, `iplink_vcan.c`, `iplink_team.c`), which closes KP5. KP3's shape carries over: a typed `<Kind>Info` with present bits, a `LinkInfo` field and a `setLinkInfoNest` branch, the replay goldens regenerated, a `<Kind>Setting` encoder, and the `kindRows` harness.
+
+**What these kinds add to KP4's shape:**
+- **No prefetch.** None of these parsers reads the device before a set, so the encoders take only the settings, as KP3's do.
+- **Attributes in word order.** hsr, netkit's own words, vrf and batadv send each attribute as its word is read, with no repeat check, so two `supervision`s, `table`s or `ra`s send two attributes. The encoders keep the order and the repeats.
+- **A peer half.** netkit's words after `peer` (when one isn't netkit's) and every vxcan word go through `iplink_parse` into `IFLA_NETKIT_PEER_INFO` or `VXCAN_INFO_PEER`: a 16-byte `ifinfomsg` holding the peer's flags, then its attributes, as `EncodeVethPeer` builds for veth. The two encoders share it rather than copy it.
+- **Nothing to decode for most.** vxcan and batadv have no `fill_info`, team none and team_slave no `fill_slave_info`, and ifb, nlmon and vcan no `IFLA_INFO_DATA` at all; their readbacks carry only `info_kind` (and `info_slave_kind`). vrf's and vrf_slave's table is decoded already (`LinkInfo.VrfTable`, `VrfPortTable`).
+- **`ll_index_to_name` again.** hsr prints `slave1`, `slave2` and `interlink` as names, and an absent slave as JSON `null`.
+
+**Counts.**
+
+| kind | rows | rc 0 | rc 2 | `ip` refused | requests |
+|---|---|---|---|---|---|
+| hsr | 29 | 10 | 10 | 9 | 20 |
+| netkit | 43 | 19 | 8 | 16 | 27 |
+| vrf | 18 | 8 | 4 | 6 | 12 |

+
+"requests" counts the rows at rc 0 or 2; a bare `type <kind>`, and every row of a kind with no parser, sends no `INFO_DATA`, and its row expects none.
+
+#### KP5-T01 The hsr parser
+
+**Code.** `xtcpnl_hsr.go`:
+- **`HsrInfo`:** `Slave1`, `Slave2`, `Interlink` (ifindexes), `SupervisionAddr` (6 bytes), `SeqNr` (u16), `Version`, `Protocol` (u8s), each with its present bit, and the short-attribute bit `hsr_print_opt` checks. `LinkInfo.Hsr`.
+- **`EncodeHsrInfoData(settings)`:** `hsr_parse_opt`: `MULTICAST_SPEC`, `VERSION` and `PROTOCOL` as u8s, `SLAVE1`, `SLAVE2` and `INTERLINK` as u32 ifindexes, each when its word is read. `ip`'s version and proto checks test `get_u8`'s return, so any u8 passes; an ifindex of 0 (`ll_name_to_index`'s miss) or a value past its width is `ErrKindSettingRange`.
+- **The render oracle:** `hsr_print_opt`: nothing at all when `SLAVE1`, `SLAVE2` or `INTERLINK` is under 4 bytes, `SEQ_NR` under 2 or `SUPERVISION_ADDR` under 6; otherwise `slave1` and `slave2` (names, `null` when absent), `interlink` when present, `seq_nr`, `supervision_addr`, `proto` and `version`. The kernel sends no `VERSION` for PRP.
+- **The benchmark:** `BenchmarkParseHsrInfoData` over `add_interlink`'s blob.
+
+`TestHsrDumpMatchesReadback`: a subtest per rc 0 row (10).

+| corner: version 2 passes `ip` | `add_version_2` | its request, `VERSION` 2 |
+| corner: the words' order is the attributes' | `s 7 sl d0 p 0 v 1 slave2 d1` | `MULTICAST_SPEC`, `SLAVE1`, `PROTOCOL`, `VERSION`, `SLAVE2` |
+
+`TestLinkInfoHsrKinds`: an hsr decodes `Hsr` (positive ×2: `add_default`, `add_proto_prp`); an ifb does not; an hsr with an interlink does (corner).
+
+**Mutation check:** the version refused above 1 (`add_version_2`); the short-attribute check dropped (the short-`SLAVE1` row); the attributes sent in id order (the word-order row, `add_prp_version`).
+
+#### KP5-T02 The netkit parser
+
+**Code.** `xtcpnl_netkit.go`:
+- **`NetkitInfo`:** `Primary` (u8), `Policy`, `PeerPolicy`, `Mode`, `Scrub`, `PeerScrub`, `Pairing` (u32s), `Headroom`, `Tailroom` (u16s), each with its present bit. `LinkInfo.Netkit`.
+- **`EncodeNetkitInfoData(settings, peer)`:** `netkit_parse_opt`: `MODE` (`l2` 0, `l3` 1), `POLICY` or, after `peer`, `PEER_POLICY` (`forward` 0, `blackhole` 2), `SCRUB` or `PEER_SCRUB` (`none` 0, `default` 1), each as its word is read; then, when the peer has words of its own, `PEER_INFO` holding the peer's `ifinfomsg` and attributes, shared with `EncodeVethPeer`. A second `mode` or `peer` is `ErrKindSettingConflict` (`duparg`), and a mode, policy or scrub outside its names `ErrKindSettingRange`. `peer` alone sends an empty `INFO_DATA`, which is not none.
+- **The render oracle:** `netkit_print_opt`: `mode` (`l2`, `l3`, else `UNKNOWN`), `type` (`primary` or `peer`), `policy` and `peer_policy` (`forward`, `blackhole`, else `UNKNOWN`), `scrub` and `peer_scrub` (`none`, `default`, else `UNKNOWN`), each when sent. Headroom, tailroom and pairing aren't printed.
+- **The benchmark:** `BenchmarkParseNetkitInfoData` over `add_peer_blackhole`'s blob.
+
+`TestNetkitDumpMatchesReadback`: a subtest per rc 0 row (19).
+
+`TestParseNetkitInfoData`:
+

+| boundary: an empty nest | `[]byte{}` | an empty view |
+| corner: the peer's own dump | `set_on_peer` | type `peer` |
+| corner: no scrub on a single device | built without `SCRUB` | no `scrub` key |
+
+`TestEncodeNetkitInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | the 27 rows that sent one | byte-identical to `ip.pcap`'s |
+| negative: a second mode | `mode l3 mode l2` | `ErrKindSettingConflict` |
+| negative: a second peer | `peer peer` | `ErrKindSettingConflict` |
+| negative: a policy with no name | built `POLICY` 1 | `ErrKindSettingRange` |
+| negative: a peer half with no peer word | a `VethPeer` and no `peer` setting | `ErrKindSettingMissing` |
+| negative: a setting with no option | the zero option | `ErrKindSettingOption` |
+| boundary: no settings | `nil` | `nil` |
+| boundary: `peer` alone | `peer` | an empty, non-nil `INFO_DATA` |
+| corner: `peer` splits the policy words | `forward peer blackhole` | `POLICY` 0, then `PEER_POLICY` 2 |
+| corner: the peer's header carries its flags | `peer`, the peer `IFF_UP` | `PEER_INFO`'s `ifinfomsg` with `IFF_UP` |
+| corner: `PEER_INFO` follows netkit's words | `blackhole peer name nt1` | `POLICY` 2, then `PEER_INFO` holding `IFNAME` `nt1` |
+| corner: a netkit word after `peer` stays netkit's | `peer mode l2` | `MODE` 0, no `PEER_INFO` |
+
+`TestLinkInfoNetkitKinds`: a netkit decodes `Netkit` (positive ×2: the primary and, through `set_on_peer`, the peer); a vxcan does not (negative, `vxcan/add_peer`); an l2 netkit does (corner).
+
+**Mutation check:** a policy after `peer` sent as `POLICY` (`add_peer_blackhole`); `PEER_INFO` placed before the netkit words (`corner: PEER_INFO follows netkit's words`); a second `mode` accepted (the second-mode row).
+
+#### KP5-T03 The vrf, vrf_slave and vxcan parsers
+
+**Code.** `xtcpnl_vrf.go` and `xtcpnl_vxcan.go`:
+- **vrf decodes as it does today:** `LinkInfo.VrfTable` and `VrfPortTable` are unchanged, and the task adds what was missing: the corpus tests and the encoder. The `LinkInfo` comments that say only vrf and bond are decoded are brought up to date.
+- **`EncodeVrfInfoData(settings)`:** `vrf_parse_opt`: one `TABLE` u32 per `table` word, in order, the name already resolved (`main` is 254); a value past 32 bits is `ErrKindSettingRange`. The kernel's nonzero check stays the kernel's (`add_table_zero` is its refusal).
+- **vrf_slave has no parser:** a test that every vrf_slave request carries no `INFO_SLAVE_DATA`, and that an enslaved device's `VrfPortTable` renders as its readback's `table`.
+- **`EncodeVxcanInfoData(peer)`:** `vxcan_parse_opt`: always one `VXCAN_INFO_PEER` holding the peer's `ifinfomsg` and attributes, `peer` alone included, through the helper `EncodeVethPeer` and `EncodeNetkitInfoData` share.
+- **The render oracles:** vrf: `table`. vrf_slave: `table` under `info_slave_data`. vxcan: nothing, since the kernel sends no `INFO_DATA`.
+- **The benchmark:** `BenchmarkParseVrfInfoData` over `vrf/add_table`'s blob, timing `vrfTableAttr`.
+
+`TestVrfDumpMatchesReadback`: a subtest per rc 0 vrf row (8) and per vrf_slave row whose readback has a slave kind (3).
+
+`TestEncodeVrfInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | vrf's 12 rows that sent one | byte-identical to `ip.pcap`'s |
+| negative: a table past 32 bits | `1 << 32` | `ErrKindSettingRange` |
+| negative: a setting with no option | the zero option | `ErrKindSettingOption` |
+| boundary: no settings | `nil` | no bytes |
+| boundary: the highest table | `table 4294967295` | `TABLE` 0xffffffff |
+| corner: two tables send two attributes, in order | `table 20 table 10` | `TABLE` 20, then `TABLE` 10 |
+| corner: table 0 is sent | `table 0` | `TABLE` 0: the kernel refuses it (`add_table_zero`) |
+
+`TestEncodeVxcanInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | vxcan's 9 rows that sent one | byte-identical to `ip.pcap`'s |
+| negative: a peer attribute too long for the buffer | a peer `IFLA_IFALIAS` of the buffer's size | an error, no bytes |
+| boundary: no option words | a nil peer | `nil` |
+| boundary: `peer` alone | `peer` | one `VXCAN_INFO_PEER` holding a zero `ifinfomsg` |
+| corner: a bare word names the peer | `peer vc1` | the peer's `IFNAME` `vc1`, as `add_peer_name` sends |
+| corner: the peer's flags | `peer up` | `IFF_UP` in the peer's `ifinfomsg` |
+
+`TestKindSlaveDataAbsent` (vrf_slave's half): every vrf_slave request has no `INFO_SLAVE_DATA` (negative, a subtest per row: 10); `set_master`'s and `set_type`'s readbacks decode `VrfPortTable` 10 (positive ×2); `set_nomaster`'s has no slave kind (corner).
+
+**Mutation check:** the repeated table dropped (`add_table_twice`); vxcan's peer nest skipped for `peer` alone (`add_peer`); the peer's flags left in the outer header (`add_peer_up`, vxcan's and netkit's).
+
+#### KP5-T04 The batadv parser and the kinds with no parser
+
+**Code.** `xtcpnl_batadv.go`:
+- **`EncodeBatadvInfoData(settings)`:** `batadv_parse_opt`: one NUL-terminated `IFLA_BATADV_ALGO_NAME` per `ra` word, in order, unchecked. The kernel's name check stays the kernel's.
+- **No decoder:** batadv has no `fill_info`, so `LinkInfo` gains nothing, and a dump's `INFO_DATA` is never there to decode.
+- **The kinds with no parser:** ifb, nlmon, vcan, team and team_slave. A test that none of their requests carries `INFO_DATA` or `INFO_SLAVE_DATA`, that their dumps carry none, and that `ParseNewLink` leaves every kind field nil for them.
+- **The benchmark:** `BenchmarkEncodeBatadvInfoData` over `ra BATMAN_V`, since there's nothing to parse.
+
+`TestEncodeBatadvInfoData`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row's request | the 12 rows that sent one | byte-identical to `ip.pcap`'s |
+| negative: a name with a NUL | built | `ErrKindSettingRange` |
+| negative: a setting with no option | the zero option | `ErrKindSettingOption` |
+| boundary: no settings | `nil` | no bytes |
+| boundary: an empty name | built `ra ""` | one attribute holding the NUL alone |
+| corner: two names send two attributes, in order | `ra BATMAN_V ra BATMAN_IV` | `BATMAN_V`, then `BATMAN_IV` |
+| corner: the case is kept | `ra batman_v` | `batman_v`, as `add_ra_lowercase` sends it |
+

+**Mutation check:** the NUL dropped from `ALGO_NAME` (every batadv request); the repeated name dropped (`add_ra_twice`); a parser-less kind's dump given a decoder that returns non-nil on a nil nest (the ifb row). It closes KP5.
+
+### KG0 — goip `link set inet`
+
+Two tasks: KG0-T01 puts `inet` in goip's `iplink_parse` keyword chain and replays the KC1 rows offline; KG0-T02 adds the matrix rows and gates them, which closes KG0. The codec is KP0's (`pkg/xtcpnl/xtcpnl_inet_devconf.go`), so KG0 is argument parsing, exit statuses and the matrix.
+
+**What `ip` does** (`ip/iplink.c` at `v7.2.0`):
+- **The keyword.** `strcmp(*argv, "inet")` (`:946`) sits after `mtu` and before the xdp keywords. It is `strcmp`, so `ine` falls through to the device-name arm. goip's chain (`linkParseKeywords`) has no `inet` today, so `ip link set dev d0 inet …` reads `inet` as a second device name and refuses with `duparg2`'s text: a wrong refusal, not a wrong request.
+- **The loop** (`iplink_parse_inet`, `:572-860`). It opens `IFLA_AF_SPEC`, `AF_INET` and `IFLA_INET_CONF | NLA_F_NESTED`, then, while a word follows, compares it with `strcmp` against the 32 params in `InetDevconfParams`' order:
+  - An on/off param's value goes through `parse_on_off`, which takes exactly `on` or `off`. Anything else prints `Error: argument of "<param>" must be one of "off", "on", not "<value>"` and returns the error, so `ip` exits 1.
+  - A numeric param's value goes through `get_integer` base 0 into a C `int`, sent through `addattr32`, so `-1` is `0xffffffff`. A bad value is `invarg("Invalid \"<param>\" value\n")`, exit 255.
+  - A param with no value is `NEXT_ARG`'s `incomplete_command`, exit 255.
+  - The first word that isn't a param is pushed back (`PREV_ARG`), and the loop ends. If no param was read, it's `incomplete_command`, so a bare `inet` and `inet bogus on` both exit 255.
+- **The pushed-back word** returns to `iplink_parse`'s loop as the next keyword or device name, so `inet forwarding on mtu 1400` sends `IFLA_AF_SPEC` and then `IFLA_MTU` in one request, and `inet forwarding on bogus` is `duparg2` on `bogus` (`dev d0` already named the device).
+- **No repeat check.** A param twice sends two attributes, and `inet` twice sends two `IFLA_AF_SPEC` attributes.
+
+**Exit statuses.** `ip` exits 255 on `invarg`, `duparg`, `duparg2` and `incomplete_command`, and 1 on a returned parse error. goip exits 1 on every argument error today (`exitCodeOf`'s `ErrInvalidArgument` arm). The decision log already says KG0 matches the status as well as the text. KG0-T01 adds `ErrLinkUsage`, which `exitCodeOf` maps to `ExitMinusOne`, and wraps every refusal `parseLinkArgs` returns where `ip` calls `exit(-1)`. The shared helpers (`invargErr`, `dupargErr`, `incompleteErr`) stay as they are, since most of goip's other objects use them. The kind parsers (`parseBondArgs`) keep 1 until their KG phase.
+
+#### KG0-T01 `inet` in goip's keyword chain
+
+**Code.** In `internal/goip/link_write.go`:
+- **`{keyword: "inet", arm: linkArmInet}`** goes in `linkParseKeywords` between `mtu` and `xdpgeneric`, with no prefix.
+- **`(*linkParseState).inet(args, i) (int, error)`** reads params from `args[i+1:]` against `xtcpnl.InetDevconfParams`, builds `[]xtcpnl.InetDevconfSetting`, and appends `xtcpnl.LinkAttrInetDevconf`'s attribute to `st.out.attrs` where the word fell. It returns the index of the last word it consumed, so the loop's `i++` lands on the pushed-back word.
+- **Values:** on/off is `on` 1 and `off` 0, refused with `parse_on_off`'s text above, wrapped in `ErrInvalidArgument` (exit 1). Numeric values go through `getInteger(v, 0)`, the value taken as the C `int`'s 32 bits without a narrowing conversion that gosec flags. A bad value is the `invarg` text, wrapped in `ErrLinkUsage`.
+- **`ErrLinkUsage`** in `goip.go`, with an `exitCodeOf` arm mapping it to `ExitMinusOne`, ahead of the `ErrInvalidArgument` arm. `parseLinkArgs` wraps its `exit(-1)` refusals in it: `incomplete_command`, `duparg`, `duparg2`, and the name and alias `invarg`s. The existing link tests that expect 1 for those move to 255.
+
+`TestLinkSetInetMatchesIp`, which replays `pkg/xtcpnl/testdata/7_3_0/link-write/rtnl/inet_*` through `newLinkReplay`: goip sends `ip`'s d0 lookup and writes `ip`'s request, byte for byte with seq and pid zeroed, and exits 0 with nothing printed.
+
+| description | input | expected |
+|---|---|---|
+| positive: one on/off param | `inet_forwarding_on` | one lookup, then its request |
+| positive: several params, in argument order | `inet_several` | its request: ids 1, 3, 8 and 19 in that order |
+| positive: every param | `inet_every_param` | its request: 32 attributes |
+| positive: a numeric param at the top of the kernel's range | `inet_rp_filter_max` | its request |
+| negative: a request the kernel refuses is built anyway | `inet_rp_filter_over`, `inet_medium_id_neg2` | their requests; the `EINVAL` is the kernel's |
+| boundary: base 0 | `inet_tag_hex`, `inet_arp_ignore_octal` | `TAG` 16; `ARP_IGNORE` 8 |
+| boundary: the one signed param | `inet_medium_id_neg1` | `MEDIUM_ID` `0xffffffff` |
+| corner: the pushed-back word is the next keyword | `inet_then_mtu` | `IFLA_AF_SPEC`, then `IFLA_MTU` |
+| corner: a repeated param | `inet_repeated` | both attributes, 1 then 0 |
+
+`TestLinkSetInetRefusals`: goip's status and stderr for a refusal. Nothing is sent: `ip` refuses inside its loop, before the d0 lookup.
+
+| description | input (`link set dev d0 …`) | expected |
+|---|---|---|
+| negative: each `ip`-refused KC1 row | the 7 rows at rc 1 or 255 | the row's `ip.rc`, and its `ip.err` text on stderr |
+| negative: an on/off param given a number | `inet forwarding 1` | rc 1, `must be one of "off", "on", not "1"` |
+| negative: a numeric param given `on` | `inet rp_filter on` | rc 255, `Invalid "rp_filter" value` |
+| boundary: a value past a C `int` | `inet tag 2147483648` | rc 255, `Invalid "tag" value` |
+| boundary: `inet` as the last word | `inet` | rc 255, `Command line is not complete` |
+| corner: `ine` is a device name | `ine forwarding on` | rc 255, `either "dev" is duplicate, or "ine" is garbage` |
+| corner: a param word outside `inet` | `forwarding on` | rc 255, the same text for `forwarding` |
+| corner: an existing refusal moves to 255 | `mtu 1400 mtu 1500` | rc 255, `duplicate "mtu"` |
+
+`TestLinkSetInetBuilt`: requests no row captured, built with `xtcpnl.LinkAttrInetDevconf` as the expectation.
+
+| description | input (`link set dev d0 …`) | expected |
+|---|---|---|
+| positive: one numeric param | `inet arp_announce 2` | one `IFLA_AF_SPEC` holding `ARP_ANNOUNCE` 2 |
+| corner: `inet` twice | `inet forwarding on inet proxy_arp on` | two `IFLA_AF_SPEC` attributes, in order |
+| corner: a generic keyword before `inet` | `mtu 1400 inet forwarding on` | `IFLA_MTU`, then `IFLA_AF_SPEC` |
+| boundary: the highest id | `inet arp_evict_nocarrier off` | `ARP_EVICT_NOCARRIER` (33) 0 |
+
+`TestErrLinkUsageExitCode`: `exitCodeOf`'s arm order.
+
+| description | input | expected |
+|---|---|---|
+| positive: a link usage refusal | `linkUsage(incompleteErr())` | 255 |
+| negative: a plain argument error | `incompleteErr()` | 1 |
+| corner: wrapped again | `errors.Join(linkUsage(…))` | 255 |
+
+The replay tests set `req.LLMapNameOnly`, since the 7.3.0 corpus's d0 lookups carry 7.2.0's `IFLA_EXT_MASK` (0x109) and `main_test.go` defaults to 7.1.0's.
+
+**Mutation check:** the params matched by prefix (`inet_abbreviated`); the pushed-back word consumed (`inet_then_mtu`); values read base 10 (`inet_tag_hex`); `ErrLinkUsage` mapped to 1 (the `ip`-refused rows); `inet` given `prefix: true` (the `ine` corner).
+
+**Done when:** the tables pass with `go test -count=1 -race ./internal/goip/`, `go vet` passes, the mutants are killed, and lint-baseline and netlink-audit pass.
+
+#### KG0-T02 The `inet` matrix rows
+
+**Rows.** In `internal/goipparity/commands.go`, after the link write rows: one write row per kernel-answered KC1 row, 11 in all, in KC1-T01's order. Each is `link set dev d0 inet …` as KC1 ran it, with `Setup: linkWriteSetupDummy`, `Floor: 4` (d0's lookup, the write and its answer), and `Implemented: true, Write: true`. The `ip`-refused rows aren't matrix rows, since a write row needs goip to exit 0. `TestLinkSetInetRefusals` holds them offline, as `TestRouteWriteNodevCorpus` holds `nodev`.
+
+`TestInetMatrixRows` (in `internal/goipparity`):
+
+| description | input | expected |
+|---|---|---|
+| positive: the rows are KC1's kernel-answered rows, in order | the `link_inet_*` slugs | `inet_forwarding_on` … `inet_then_mtu`, 11 |
+| negative: no `ip`-refused row is a matrix row | the 7 refused slugs | absent |
+| boundary: each row's floor | `Floor` | 4 |
+| corner: every row sets up d0 alone | `Setup` | `linkWriteSetupDummy` |
+| positive: every row is gated | `nlparity.EmbeddedAllowlist().IsGated` | true for all 11 |
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: two consecutive clean runs | `nix run .#microvm-x86_64-goip-parity -- --timeout 12000` (the full table), then the same with `--section link` | the 11 rows `PASS` on both, and every gated row the run holds still `PASS` |
+| corner: the refused rows compare on the request | `inet_rp_filter_over`, `inet_medium_id_neg2` | `PASS`: `ip` exits 2 on both sides, goip 0 |
+
+Then the 11 rows go in `gated_commands` (`pkg/nlparity/goip-parity-allowlist.json`).
+
+**Mutation check:** a row's floor at 2 (the floor row); a refused row added (the negative row); a row dropped from `gated_commands` (the gated row).
+
+**Done when:** the offline tables pass; the two VM runs are clean; the rows are gated; lint-baseline passes. It closes KG0.
+
+### KG1 — goip bridge
+
+Five tasks: KG1-T01 and KG1-T02 parse `type bridge` and `type bridge_slave` words into KP1's encoders and replay KC2's requests; KG1-T03 and KG1-T04 render the two kinds' `-d` and `-d -j` output; KG1-T05 adds the matrix rows and gates them, which closes KG1. The codec is KP1's (`pkg/xtcpnl/xtcpnl_bridge.go`, `xtcpnl_bridge_slave.go`), which decodes into `LinkInfo.Bridge` and `LinkInfo.BridgeSlave` but renders nothing, so KG1 is argument parsing, exit statuses, the renderer and the matrix.
+
+**The rows** (`pkg/xtcpnl/testdata/7_3_0/link-write/kinds/`, argv in `kind-write-corpus.exp`):
+
+| kind | rows | rc 0 | rc 2 (kernel) | rc 1 / 255 (`ip`, before the write) | requests |
+|---|---|---|---|---|---|
+| bridge | 60 | 50 | 5 | 2 / 3 | 55 |
+| bridge_slave | 42 | 30 | 7 | 2 / 3 | 37 |
+
+**What `ip` does** (`ip/iplink_bridge.c`, `iplink_bridge_slave.c` at `v7.2.0`):
+- **Keywords.** `bridge_parse_opt` is a `matches`/`strcmp` chain in its own order, which isn't `bridge_print_opt`'s; `BridgeOptionSpec.Match` says which (KP1-T01). `bridge_slave_parse_opt` likewise, with `nobackup_port` (no row in `BridgeSlaveOptions`: it sends `backup_port` 0) and `fdb_flush`.
+- **Statuses.** An unknown word returns from `parse_opt`, so `ip` prints `bridge: unknown command "<w>"?` (`bridge_slave: unknown option "<w>"?`) and its usage, and exits 1. A bad `stp_mode` returns too (1), as does `bridge_slave_parse_on_off`'s `exit(1)`. `invarg` and `incomplete_command` exit 255.
+- **Lookups.** `ip link set dev p0 type bridge_slave …` looks p0 up before the kind's words are read, so even a slave refusal sends p0's get. `backup_port` resolves its name with `ll_name_to_index`, a get, before `invarg("Device does not exist")`. A bridge `add` refusal sends nothing.
+- **Rendering.** `_bridge_print_timer` prints jiffies as `"%s %4i.%.2i "` (`gc_timer    0.00`) and, in JSON, a raw number (`0.00`). `br_dump_bridge_id` prints `%.2x%.2x.` and `ether_ntoa_r`'s unpadded address (`8000.0:0:0:0:0:0`). `vlan_protocol` goes through `ll_proto_n2a` (`802.1Q`), `group_fwd_mask` through `%#llx` (`0` for zero), the querier state through `lib/bridge.c`'s `bridge_print_mcast_querier_state`. A port prints `port_id`/`port_no` as hex (JSON `id`, `no`), its state by name, `group_fwd_mask_str`, and `backup_port` through `ll_index_to_name`.
+
+**Exit statuses.** KG0's decision holds: goip matches `ip`'s status. The bridge parsers wrap `invarg` and `incomplete_command` in `ErrLinkUsage` (255) and return the rest as `ErrInvalidArgument` (1). The bond parsers are unchanged until KG5.
+
+#### KG1-T01 The bridge words
+
+**Code.** `internal/goip/link_bridge_args.go`, following `link_bond_args.go`: `parseBridgeArgs(errOut io.Writer, args []string) ([]xtcpnl.BridgeSetting, error)`, its chain in `bridge_parse_opt`'s order, each arm pointing at its `xtcpnl.BridgeOptions` row by keyword and matched by its `Match`. Values by `Wire`: unsigned through `get_u*`'s bases (a boolopt word is a `get_u8`), `group_address` as a MAC, `vlan_protocol` through `ll_proto_a2n` (`internal/goip/ll_proto.go`), `stp_mode` by name through `parse_one_of`, whose prefix warning goes to `errOut`. `xtcpnl.EncodeBridgeInfoData` collects the five boolopts into one `MULTI_BOOLOPT`. A `kindBridgeCst` case in `kindData` calls it.
+
+`TestLinkBridgeWriteMatchesIp`, replaying `kinds/bridge/*` through `newLinkReplay` with `useLLMap720`: goip sends `ip`'s lookups and writes `ip`'s request, byte for byte with seq and pid zeroed, and exits 0.
+
+| description | input | expected |
+|---|---|---|
+| positive: each row that sent a request | the 55 rows | its lookups, then its request |
+| positive: the defaults | `add_default` | `IFLA_INFO_KIND` bridge, no `INFO_DATA` |
+| negative: a request the kernel refuses is built anyway | the 5 rc 2 rows | their requests |
+| boundary: the boolopts in one attribute | `add_boolopts` | one `MULTI_BOOLOPT`, last |
+| corner: a `matches` keyword abbreviated | `add_abbrev` (`forward_d 400`) | `FORWARD_DELAY` |
+| corner: a set prefetches br0 | `set_ageing_time` | br0's get, then the set |
+
+`TestBridgeCorpusArgv` holds the argv table to the corpus: one argv per `kinds/bridge/` row, 60. `TestBridgeParseChain` holds the chain: every keyword finds its row, every settable row is in the chain, 41 arms, and `mcast_q` is `mcast_query_use_ifaddr`. `TestParseBridgeArgs` holds the values no capture covers: `vlan_protocol` by number and by a name in another case, a u64 interval at its top, and `stp_mode k`, which warns and goes on.
+
+`TestLinkBridgeRefusals`: status and stderr's first line (goip prints no usage, as for bond).
+
+| description | input | expected |
+|---|---|---|
+| negative: each `ip`-refused row | `add_stp_mode_abbrev`, `add_stp_mode_bad` (1); `add_no_value`, `add_priority_bad`, `add_vlan_protocol_bad` (255) | the row's `ip.rc`, its `ip.err` first line, nothing sent |
+| negative: an unknown word | `type bridge bogus 1` | 1, `bridge: unknown command "bogus"?` |
+| negative: a bad group address | `group_address zz` | 1, `"zz" is invalid lladdr` |
+| boundary: a u16 one past its range | `priority 65536` | 255, `argument "65536" is wrong: invalid priority` |
+| boundary: a boolopt word is a u8 | `mst_enabled 256` | 255, invalid `mst_enabled` |
+| corner: a `strcmp` keyword abbreviated | `mst_en 1` | 1, unknown command |
+| corner: help is not goip's | `help` | 1, not implemented |
+
+**Mutation check:** every keyword matched by prefix (`add_stp_mode_abbrev`, `mst_en 1`); a boolopt read as a u32 (`mst_enabled 256`); `invarg` mapped to 1 (the 255 rows); `mcast_querier` tried first (the chain's corner row); `ll_proto_a2n` with case (the name in another case). `MULTI_BOOLOPT` per word is the encoder's, which KP1 held.
+
+**Done when:** the tables pass with `go test -count=1 -race ./internal/goip/`, `go vet` passes, the mutants are killed, and lint-baseline and netlink-audit pass.
+
+#### KG1-T02 The bridge_slave words
+
+**Code.** `internal/goip/link_bridge_slave_args.go`: `parseBridgeSlaveArgs(args []string, resolve linkResolver) ([]xtcpnl.BridgeSetting, error)`, `bridge_slave_parse_opt`'s chain (`nobackup_port`, which has no row, tried after it, which is the same as its place in it). `state` is a `get_u8` number (the names are print-only), on/off words go through `bridge_slave_parse_on_off`'s text, `backup_port` resolves through the resolver (a get) and `nobackup_port` sends 0. A `kindBridgeSlaveCst` case in `kindData` calls `xtcpnl.EncodeBridgeSlaveData`.
+
+`TestLinkBridgeSlaveWriteMatchesIp`, as KG1-T01's over `kinds/bridge_slave/*`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each row that sent a request | the 37 rows | p0's get (and p1's for `backup_port p1`), then its request |
+| positive: the backup port by name | `set_backup_port` | p1's get, `BACKUP_PORT` p1's index |
+| negative: a request the kernel refuses is built anyway | the 7 rc 2 rows | their requests |
+| boundary: no backup port | `set_nobackup_port` | `BACKUP_PORT` 0, no get |
+| corner: an abbreviation | `set_abbrev` (`co 10`) | `COST` 10 |
+| corner: a port that isn't enslaved | `set_not_enslaved` | the request; the `EOPNOTSUPP` is the kernel's |
+
+`TestLinkBridgeSlaveRefusals`:
+
+| description | input | expected |
+|---|---|---|
+| negative: each `ip`-refused row | `set_strcmp_abbrev`, `set_on_off_bad` (1); `set_backup_port_missing`, `set_cost_bad`, `set_no_value` (255) | the row's `ip.rc` and `ip.err` first line; p0's get sent, and nosuch's for `set_backup_port_missing`; no write |
+| negative: an unknown word | `bogus on` | 1, `bridge_slave: unknown option "bogus"?` |
+| boundary: a state past a u8 | `state 256` | 255, `argument "256" is wrong: state is invalid`, after p0's get |
+| negative: a state by name | `state forwarding` | 255, `state is invalid` (the names are print-only) |
+| corner: `nobackup_port` with a value after it | `nobackup_port p1` | 1, unknown option `p1` |
+| corner: an on/off value by prefix | `learning of` | 1, `must be one of "off", "on", not "of"` (`parse_on_off` is a strcmp) |
+| corner: help is not goip's | `help` | 1, not implemented |
+
+`TestBridgeSlaveCorpusArgv` holds the argv table to the 42 corpus rows. `TestBridgeSlaveParseChain` holds the arms: `co` is `cost`, `neigh_forward_g` nothing, `mab` itself, `n` `neigh_suppress`, `mcast_f` `mcast_flood`, `proxy_arp_wifi` itself, `no` past the chain; 27 rows for 27 keywords, every settable row among them. `TestParseBridgeSlaveArgs` holds the values: a state by number, a hex mask, on as 1, a port by name, `nobackup_port` and `nob` as `backup_port` 0, a cost at its top, a resolver failure returned as it is and an unknown port as invarg.
+
+**Mutation check:** `nobackup_port` dropped (`set_nobackup_port`); the backup port's get skipped (`set_backup_port_missing`); `neigh_forward_grat` matched by prefix, in `xtcpnl.BridgeSlaveOptions` (`set_strcmp_abbrev`); an on/off value by prefix (`learning of`); the two invarg texts swapped (`set_cost_bad`, the state rows); an unknown port sent (`set_backup_port_missing`); `mcast_fast_leave` tried before `mcast_flood` (the chain's `mcast_f` row).
+
+**Done when:** as KG1-T01.
+
+#### KG1-T03 The bridge's `-d` output
+
+**Code.** `internal/goip/render/link_bridge.go`: `bridgeData(*xtcpnl.BridgeInfo) *KindData`, walking `xtcpnl.BridgeOptions` in print order with each row's JSON key (KP1's decision: the JSON keys aren't the keywords). Timers go into `KindData` as `json.RawMessage`, since a float can't print `0.00`. `bridge_id`, `designated_root` and `group_address` get their own formatters, the querier state its nested objects, `vlan_protocol` `xtcpnl.LLProtoN2A` (the `ll_proto` table moves to `pkg/xtcpnl/xtcpnl_ll_proto.go`, which goip's `llProtoA2N` reads too). A `BridgeKindCst` case in `render.kindData`, and `bridge` in `renderableInfoData`; the slave kinds get their own `renderableSlaveInfoData`, since a bridge port's slave kind is also `bridge` and its print_opt is KG1-T04's.
+
+`TestLinkShowDetailBridgeMatchesSidecar`, following `TestLinkShowDetailBondMatchesSidecar`: each readback replays the row's own `netlink_route_getlink_detail.pcap` (`_json.pcap` for JSON), since the timers move between the two readbacks, through `runKindShow`, whose `linkReplay` answers each get with the reply that followed it, since `show dev` sends two gets of one name. (KG1-T03 first held the replay to the main socket with `GOIP_REPLAY_PORTID`; KG1-T04 replaced that with `linkReplay`, which also records the gets.)

+
+**Mutation check:** the address padded (every row); a timer as a float (the JSON corner); an option out of print order (every row); `%#x` of 0 as `0x0` (every row); the slave gate opened to `bridge` (the mesh rows); `sprint_time64`'s second threshold off by one (its boundary); the boolopt mask ignored (`TestBridgeDataRender`); the JSON key as the keyword (every `-j` row).

+**Code.** `render/link_bridge_slave.go`: `bridgeSlaveData(*xtcpnl.BridgeSlaveInfo, NameTab) *KindData`. `slaveKindData` takes the `NameTab`, and `resolveLinkRefs` (`obj_link.go`) sends the `backup_port` get under `-d`, as it does for a bond's `active_slave`. `bridge` in `renderableSlaveInfoData`, `checkDetailSupported`'s slave arm. `mcast_fast_leave` prints `IFLA_BRPORT_FAST_LEAVE` a second time to the terminal only, so `KindData` gets `addText`, a call with no JSON key that `MarshalJSON` skips.
+
+`TestLinkShowDetailBridgeSlaveMatchesSidecar` runs `ip [-d] [-j] link show dev p0` through `runKindShow` and holds every row's gets to its capture's requests, byte for byte (`assertKindShowGets`): p0's two, br0's as its master, and p1's for a backup port.
+

+
+The two mesh rows in `TestDetailRefusedForPerKindData` turn positive: `-d link show` and `-d addr show` of the mesh topology render, br0 and its ports alike.
+
+**Mutation check:** `backup_port` by index (`set_backup_port`, the render rows); the state's boundary off by one (blocking); `group_fwd_mask_str` dropped (every row); `mcast_fast_leave` with a JSON key (every `-j` row); `addText`'s calls in the JSON (every `-j` row); the `backup_port` get dropped (`set_backup_port`); a mask name on the wrong bit (the mask corner); the unkeyed attributes printed (every row).
+
+**Done when:** as KG1-T01.
+
+#### KG1-T05 The bridge matrix rows
+
+**Rows.** In `internal/goipparity/commands.go`, after the inet rows:
+- **Write rows**, slug `link_bridge_<slug>` and `link_bridge_slave_<slug>`, one per KC2 row that sent a request (55 and 37), argv as KC2 ran it, in `kind-write-corpus.exp`'s order. `Floor` is the row's `ip.pcap` record count: 2 for an add, 4 for a set, 6 for the backup-port set. `Setup` is the row's `topology`: none for an add, `bridgeWriteSetupBr0` (`link add br0 type bridge`) for a set, `bridgeWriteSetupBr0Stp` for `set_stp_mode_busy`, `bridgeWriteSetupPorts` (br0, p0 and p1 dummies, both enslaved) for a port row, `bridgeWriteSetupPortsUp` and `bridgeWriteSetupPortsBackup` for `state`'s and `nobackup_port`'s extra steps, and `bridgeWriteSetupP0` for `set_not_enslaved`'s p0 alone. `Name` is the allowlist key, so two rows that share an argv with another row are spelled another way that sends the same request: `set_stp_mode_busy` as `link set dev br0 …` and `set_not_enslaved` as `link set p0 …`.
+- **Read rows**: `-d link show dev br0`, `-d -j link show dev br0` (floor 4), `-d link show dev p0` and `-d -j link show dev p0` (floor 6, the master's get added), on `bridgeReadSetup`, the ports' topology.
+
+The stdout comparison is the facets (`stdout.go`'s `keywords`), not the kind text, so the read rows hold the device's other lines and the timers move freely; the sidecar tests above are the text and JSON oracle.
+
+`TestBridgeMatrixRows` (`internal/goipparity/commands_bridge_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: one write row per request row | the `link_bridge_*` slugs | the corpus's 55 and 37 rows with `ip.rc` 0 or 2, 92 in all |
+| negative: no `ip`-refused row | the 10 rows with `ip.rc` 1 or 255 | absent |
+| boundary: each floor | `Floor` | the row's `ip.pcap` record count |
+| corner: each setup | `Setup` | the row's `topology` file, step for step |
+| positive: the four read rows share the ports' setup | the read rows | not writes; floors 4, 4, 6, 6; `bridgeWriteSetupPorts` |
+| positive: every row is gated | the 92 write rows' and 4 read rows' names | each `IsGated` in the embedded allowlist |
+
+`TestCompareWriteRow`'s every-write-row case runs the 92 on their own corpus captures, and `TestAllowlistCommitted` and `TestUngatedSurfaceIsNotVacuous` hold the 96 gated. The two `ageing_time` names are split in `TestAllowlistCommitted`'s list, as in the table, for misspell's US mode.
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: two consecutive clean section runs | `goip-parity -- --timeout 12000 --section link`, twice | the 96 rows `PASS` on both, and every gated `link` row still `PASS` |
+| corner: the kernel-refused rows compare on the request | the 12 rc 2 rows | `PASS` |
+
+Then the 96 rows go in `gated_commands`. A full run comes before the next push.
+
+**Mutation check:** a floor short by 2 (the floor row); a setup step dropped (the setup row); a row dropped from the table (the request-row row); an `ip`-refused row added (the negative row); a read row's floor short by 2 (the read row); a setup on an add (the setup row); a row dropped from `gated_commands` (`TestUngatedSurfaceIsNotVacuous`, the gated row); a row dropped from `TestAllowlistCommitted`'s list only (its `nothing is gated that no measured run earned` row).
+
+**Done when:** the offline tables pass; the two VM runs are clean; the rows are gated; lint-baseline passes. It closes KG1.
+
+### KG2 — goip VLAN family
+
+Five tasks. KG2-T01 adds `iplink_parse`'s `link` keyword, which every stacked kind needs, together with the vlan words. KG2-T02 adds the macvlan and macvtap words, and KG2-T03 the ipvlan and ipvtap words. KG2-T04 renders the three print_opts' `-d` and `-d -j` output. KG2-T05 adds the matrix rows and gates them, which closes KG2. The codec is KP2's (`pkg/xtcpnl/xtcpnl_vlan.go`, `xtcpnl_macvlan.go`, `xtcpnl_ipvlan.go`), which decodes into `LinkInfo.Vlan`, `LinkInfo.Macvlan` and `LinkInfo.Ipvlan` and encodes every row's `IFLA_INFO_DATA`. So KG2 is the lower device, argument parsing, exit statuses, the renderer and the matrix.
+
+**The rows** (`pkg/xtcpnl/testdata/7_3_0/link-write/kinds/`, argv in `kind-write-corpus.exp`). Each is stacked on a dummy `d0`, and a set row's topology also makes the device it sets:
+
+| kind | rows | rc 0 | rc 2 (kernel) | rc 1 / 255 (`ip`, before the write) | requests |
+|---|---|---|---|---|---|
+| vlan | 28 | 15 | 6 | 3 / 4 | 21 |
+| macvlan | 34 | 20 | 5 | 8 / 1 | 25 |
+| macvtap | 6 | 5 | 0 | 1 / 0 | 5 |
+| ipvlan | 18 | 11 | 3 | 3 / 1 | 14 |
+| ipvtap | 4 | 3 | 0 | 1 / 0 | 3 |
+
+**What `ip` does** (`ip/iplink.c`, `iplink_vlan.c`, `iplink_macvlan.c` and `iplink_ipvlan.c` at `v7.2.0`):
+- **The lower device.** `link` is a `matches` keyword in `iplink_parse` (so `l` is `link`), and it only stores the name. On a create, the end of `iplink_parse` resolves it with `ll_name_to_index`, which sends a get, and adds `IFLA_LINK` before `IFLA_IFNAME`. A name that doesn't resolve is `nodev`: `Cannot find device "<name>"`, returned (1). This happens before `parse_opt` runs, so every refused stacked add sends d0's get (its `ip.pcap` holds 2 records). On a set, `link` is read and dropped, and nothing is resolved.
+- **vlan.** Every keyword is `matches`, in the order `protocol`, `id`, the five flags, `ingress-qos-map`, `egress-qos-map`. `id` is a `get_u16` and `protocol` goes through `ll_proto_a2n`; a failure in either is `invarg` (255). A flag's value is a `strcmp` on/off, and anything else is `on_off`'s text, returned (1). The flags fold into one `IFLA_VLAN_FLAGS`, sent last when any flag word was given. A qos map is `parse_mapping`: it reads `FROM:TO` words until one has no colon, which the loop then reads as a keyword. So `egress-qos-map 5` sends an empty map and then refuses `5` as an unknown command (1). A bad number is `invarg` naming the word after `parse_mapping` has cut it at its colon, so `1:x` prints as `"1"`.
+- **macvlan and macvtap.** One parser for both. `mode`, `flag`, `macaddr`, `nopromisc`, `nodst` and `bcqueuelen` are `matches` keywords; `bclim` is a `strcmp` (so `bcl` is an unknown option). Modes, flags and the macaddr ops are `strcmp` words. Every refusal returns (1), and only `NEXT_ARG` exits 255. The macaddr ops are added in the loop and the mode and flags after it. The `nopromisc` check runs after the loop against the last mode, so `nopromisc mode passthru` is accepted. A bad macaddr op prints only the usage, so `ip.err`'s first line is the usage line, with the kind's own name in it. `ll_addr_a2n` prints `"<part>" is invalid lladdr.` for a part that isn't hex and nothing for a wrong length; `macaddr add|del` then returns (1). `macaddr set` reads addresses until one fails and leaves that word to the loop, after `ll_addr_a2n` has printed whatever it prints.
+- **ipvlan and ipvtap.** One parser for both. `mode` is followed by an `strcmp` mode, and each mode word adds its own `IFLA_IPVLAN_MODE`. `private`, `vepa` and `bridge` are `matches` and are taken once only, so a second flag word is an unknown option (1). `IFLA_IPVLAN_FLAGS` is always sent once any option follows the kind, and with no option there's no `INFO_DATA` at all (`iplink_modify` calls `parse_opt` only when `argc`).
+- **Rendering.** vlan prints `protocol` through `ll_proto_n2a` (or `802.1q` when the attribute is missing), then `id`, then the flags as `<A,B>` (a JSON `flags` array; leftover bits through `print_hex`). Each qos map starts with `print_nl()` and then prints `      ingress-qos-map { 1:2 3:4 } `; in JSON it's an array of `{from, to}`. vlan prints nothing without a full-width `IFLA_VLAN_ID`. macvlan prints `mode` by name (`unknown` past source), `nopromisc` and `nodst` as booleans, `bcqueuelen` and `usedbcqueuelen` as `%lu` and `bclim` as `%d`; only in source mode does it add `remotes (%d)` and the addresses. ipvlan prints `" mode %s "` with a leading space, so its line reads `ipvlan  mode l3 bridge`, then exactly one of `private`, `vepa` and `bridge` as a boolean.
+
+**Exit statuses.** KG0's decision holds: `invarg`, `incomplete_command` and `NEXT_ARG` wrap `ErrLinkUsage` (255), and the returned refusals are `ErrInvalidArgument` (1). goip prints a refusal's first line and no usage, as for bridge. macvlan's bad op is the exception: its first line is the usage line, so goip prints that line.
+
+#### KG2-T01 The `link` keyword and the vlan words
+
+**Code.**
+- **The keyword.** `link_write.go`'s `link` entry gets its own arm, `linkArmLink`. It stores the name in `linkParseState.link`, last one winning. `finish`'s create branch resolves the name through `st.resolve` before `IFLA_IFNAME` and appends `IFLA_LINK`, or returns `nodevErr` for a name that doesn't resolve. The set branch ignores it.
+- **The vlan words.** `internal/goip/link_vlan_args.go`: `parseVlanArgs(args []string) ([]xtcpnl.VlanSetting, error)`, `vlan_parse_opt`'s chain in its order, with `ll_proto_a2n` from `ll_proto.go`. The qos maps go through `parseQosMapping`, `parse_mapping`'s loop, which returns the argv from the word that stopped it on, and names the word cut at its colon in `invarg`. The loop walks a shrinking sub-slice rather than indexing `args[i+1]`, which gosec's G602 flags. A `kindVlanCst` case in `kindData` calls `xtcpnl.EncodeVlanInfoData`.
+
+`TestLinkVlanWriteMatchesIp` replays `kinds/vlan/*` through `newLinkReplay` with `useLLMap720`. goip must send `ip`'s lookups and write `ip`'s request, byte for byte with seq and pid zeroed, and exit 0.

+| negative: no value | `add name x0 link` | 255, `Command line is not complete` |

+
+`TestVlanCorpusArgv` checks the argv table against the corpus: one argv per `kinds/vlan/` row, 28 in all. `TestParseVlanArgs` checks the values no capture covers:
+- `protocol 0x88a8` by number;
+- a map stopped by a keyword (`egress-qos-map 1:2 gvrp on` gives the map, then the flag);
+- `reorder_hdr on reorder_hdr off` (the mask set, the flag cleared);
+- a map key in hex (`0x1:2`).
+
+**Mutation check:**
+- `IFLA_LINK` after `IFLA_IFNAME` (the lower-device row);
+- `link` resolved on a set (`set d0 l x`);
+- `nodev` as 255 (the missing-lower row);
+- the qos `invarg` naming the whole word (`add_qos_bad`);
+- `on` read as off (the flag rows; the plan's "the flags in argument order" is the encoder's, which KP2 held);
+- `id` matched by `strcmp` (`add_abbrev`).
+
+**Done when:** the tables pass with `go test -count=1 -race ./internal/goip/`, `go vet` passes, the mutants are killed, and lint-baseline and netlink-audit pass.
+
+#### KG2-T02 The macvlan and macvtap words
+
+**Code.** `internal/goip/link_macvlan_args.go`: `parseMacvlanArgs(errOut io.Writer, kind string, args []string) ([]xtcpnl.MacvlanSetting, error)`. It is `macvlan_parse_opt`'s chain, with the kind's name in the usage line and in the `nopromisc` text.
+- **The addresses.** `ll_addr_a2n`'s warnings go to `errOut`, so `cparse.go` gains `llAddrA2NPart(arg, maxLen) ([]byte, int, string)`: the bytes, `ll_addr_a2n`'s return (`maxLen+1` past the buffer, the rest unread; -1 for a refusal), and the part it printed, `""` when it failed silently on a length. `llAddrA2N` is now a wrapper over it.
+- **The word a set stops on.** `ll_addr_a2n` writes a NUL over the word's first `:` before it reads a part, so after `PREV_ARG` the chain re-reads the word cut there: `macaddr set <mac> mode:x source` is a mode. `llAddrCut` is that cut; an IPv4 address is left whole.
+- **The `nopromisc` refusal.** `xtcpnl.ErrMacvlanNopromisc` maps to `<kind>: nopromisc flag only valid in passthru mode`.
+- **The kind cases.** `kindMacvlanCst` and `kindMacvtapCst` cases in `kindData` call `xtcpnl.EncodeMacvlanInfoData`.

+
+#### KG2-T04 The VLAN family's `-d` output
+
+**Code.**
+- `internal/goip/render/link_vlan.go`: `vlanData(*xtcpnl.VlanInfo) *KindData`. The flags are `vlan_print_flags`, in `xtcpnl.VlanFlags`' order. Each qos map is a text call of `"\n"` (`print_nl`) and then its tokens, with its JSON array as one keyed call.
+- `render/link_macvlan.go`: `macvlanData(*xtcpnl.MacvlanInfo) *KindData`, macvtap's too.
+- `render/link_ipvlan.go`: `ipvlanData(*xtcpnl.IpvlanInfo) *KindData`, ipvtap's too.
+- `render.kindData` gets the five kinds' cases, and `renderableInfoData` gets the five kinds.
+
+`TestLinkShowDetailVlanFamilyMatchesSidecar` runs `ip [-d] [-j] link show dev <row's device>` through `runKindShow` for every accepted row of the five kinds. It holds the gets to the capture's requests with `assertKindShowGets`: the device's two, and d0's by index for `@d0`.

+
+**Done when:** as KG2-T01.
+
+#### KG2-T05 The VLAN family matrix rows
+
+**Rows.** In `internal/goipparity/commands.go`, after the bridge rows:
+- **Write rows**, slug `link_<kind>_<slug>`, one per corpus row that sent a request: 21 vlan, 25 macvlan, 5 macvtap, 14 ipvlan and 3 ipvtap, 68 in all.
+  - Argv is as the corpus ran it. `Floor` is the row's `ip.pcap` record count, and `Setup` is its `topology`.
+  - `Name` is the allowlist key, so a row that shares an argv with another row is spelled another way that sends the same request. `ipvlan/add_on_busy_lower` shares `add_default`'s argv, and becomes `link add link d0 dev i0 type ipvlan`.
+  - `corpusWriteRow`'s bridge mapping becomes a table of slug prefixes and kinds, so the five kinds read their fixtures from `7_3_0/link-write/kinds/<kind>/`.
+- **Read rows**: `-d link show dev <dev>` and `-d -j link show dev <dev>` for v0, m0, t0, i0 and j0, floor 6, each on d0 plus its device's add, 10 in all.
+
+`TestVlanFamilyMatrixRows` (`internal/goipparity/commands_vlan_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: one write row per request row | the five kinds' slugs | the corpus's rows with `ip.rc` 0 or 2: 21, 25, 5, 14, 3 |
+| negative: no `ip`-refused row | the 22 rows with `ip.rc` 1 or 255 | absent |
+| boundary: each floor | `Floor` | the row's `ip.pcap` record count |
+| corner: each setup | `Setup` | the row's `topology` file, step for step |
+| corner: each name is unique | the 68 `Name`s | no two alike; `add_on_busy_lower` respelled |
+| positive: the ten read rows | the read rows | not writes; floor 6; d0 and the device |
+| positive: every row is gated | the 78 rows' names | each `IsGated` in the embedded allowlist |
+
+`TestCompareWriteRow`'s every-write-row case runs the 68 on their own corpus captures, and `TestAllowlistCommitted` and `TestUngatedSurfaceIsNotVacuous` hold the 78 gated, so the 78 go in `TestAllowlistCommitted`'s earned list too.
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: two consecutive clean section runs | `goip-parity -- --timeout 12000 --section link`, twice | the 78 rows `PASS` on both, and every gated `link` row still `PASS` |
+| corner: the kernel-refused rows compare on the request | the 14 rc 2 rows | `PASS` |
+
+Then the 78 rows go in `gated_commands`. A full run comes before the next push.
+
+**Mutation check:**
+- a floor short by 2 (the floor row);
+- a setup step dropped (the setup row);
+- a row dropped (the request-row row);
+- an `ip`-refused row added (the negative row);
+- `add_on_busy_lower` back to its corpus spelling (the unique row);
+- a read row's floor short by 2 (the read row);
+- a row dropped from `gated_commands` (the gated row and `TestUngatedSurfaceIsNotVacuous`).
+
+**Done when:** the offline tables pass; the two VM runs are clean; the rows are gated; lint-baseline passes. It closes KG2.
+
+### KG3 — goip UDP overlays
+
+Five tasks. KG3-T01 adds the vxlan words, KG3-T02 the geneve words, and KG3-T03 the bareudp, amt and gtp words. KG3-T04 renders the five print_opts' `-d` and `-d -j` output, and vxlan's `-d -d`. KG3-T05 adds the matrix rows and gates them, which closes KG3. The codec is KP3's (`pkg/xtcpnl/xtcpnl_vxlan.go`, `xtcpnl_geneve.go`, `xtcpnl_bareudp.go`, `xtcpnl_amt.go`, `xtcpnl_gtp.go`), which decodes into `LinkInfo` and encodes every row's `IFLA_INFO_DATA` in `ip`'s attribute order. So KG3 is the words, the in-loop lookups, `ip`'s checks and texts, the renderer and the matrix.
+
+**The rows** (`pkg/xtcpnl/testdata/7_3_0/link-write/kinds/`, argv in `kind-write-corpus.exp`). vxlan's `dev d0` rows and every amt row run on a dummy `d0`, and a set row's topology also makes the device it sets:
+
+| kind | rows | rc 0 | rc 2 (kernel) | rc 1 / 255 (`ip`, before the write) | requests |
+|---|---|---|---|---|---|
+| vxlan | 73 | 46 | 12 | 8 / 7 | 58 |
+| geneve | 49 | 22 | 13 | 7 / 7 | 35 |
+| bareudp | 16 | 6 | 4 | 1 / 5 | 10 |
+| amt | 20 | 5 | 8 | 3 / 4 | 13 |
+| gtp | 19 | 7 | 4 | 3 / 5 | 11 |
+
+**What `ip` does** (`ip/iplink_vxlan.c`, `iplink_geneve.c`, `iplink_bareudp.c`, `iplink_amt.c`, `iplink_gtp.c` and `lib/utils.c` at `v7.2.0`):
+- **vxlan.** Its keywords are `matches`, except `localbypass`, `nolocalbypass`, `reserved_bits`, `vnifilter`, `novnifilter`, `mcroute` and `nomcroute`, which are `strcmp`. The chain's order decides each abbreviation: `d` is `dev`, `l` is `local`, `p` is `port` (the source range, not `dstport`), `n` is `nolearning`.
+  - Each value word is `check_duparg`ed on its attribute. `group` and `remote` share `IFLA_VXLAN_GROUP`, a learning word and its `no` form share one, and `reserved_bits` passes its value as the key, so a second one names the value twice.
+  - `group` and `remote` refuse the other before `NEXT_ARG`, so `remote` with no value after a group is the conflict (1), not an incomplete command.
+  - Addresses go through `get_addr` with the other address's family: a remote's for the local, the local's for a group or remote. A failure is `exit(1)`, `Error: <family> address is expected rather than "<word>".`. `any` parses as no family and fails the `is_addrtype_inet_not_multi` check (`invarg`), while `0.0.0.0` passes and is sent.
+  - `dev` resolves inside the loop through `ll_name_to_index`, which sends a get, and a name that doesn't resolve is `exit(nodev)`: 255, unlike `iplink_parse`'s `link` (1).
+  - After the loop, in this order: vnifilter without external, external with an id, no id on an add, a group without `dev` (each 1); then the four-line dstport warning on stderr for an add with neither `dstport` nor `gpe`. Then the held-back attributes, which `EncodeVxlanInfoData` already orders.
+  - With no address given, `ip -4` and `ip -6` send a default `IFLA_VXLAN_GROUP` 0.0.0.0 or `IFLA_VXLAN_GROUP6` `::`, after the local's place. The encoder doesn't model it (KP3's decision log).
+- **geneve.** Its keywords are `matches`, except 7.2.0's `local` and `innerprotoinherit` (`strcmp`); `l` is `label`, and `d` is `dsfield`, which is `tos`. Both addresses go through `get_addr` with no family, so a local of the remote's other family reaches the kernel. `ttl inherit` adds `IFLA_GENEVE_TTL_INHERIT` in the loop; everything else is held. After the loop: external with an id, then (without external) no id, then no remote on an add (each 1). ID always follows, then LABEL, TTL and TOS on an add or when given.
+- **bareudp.** Every keyword is `matches`; `multiproto` and `nomultiproto` share a duparg. After the loop, a missing `dstport`, then a missing `ethertype`, is `missarg` (255, `Error: argument "<word>" is required`).
+- **amt.** Every keyword is `strcmp`, and only `local` and `discovery` are dupargs, so a second `mode` is sent twice. A bad mode prints only the usage (1), whose first line is `Usage: ... amt`. `dev` resolves in the loop with `exit(nodev)`, as vxlan's. `local` reads its family from the discovery address, and an address is sent when `is_addrtype_inet`: `0.0.0.0` and multicast go out, and `any` is skipped.
+- **gtp.** `IFLA_GTP_CREATE_SOCKETS` goes first once any word follows the kind. Every keyword is `strcmp`, and any other word is skipped silently, so `rol ggsn` is two skipped words. `restart_count` is `get_u8` in base 10, so `0x1` is `invarg`. No role is returned (1). `PDP_HASHSIZE` 1024 is added when no `hsize` was given.
+- **Rendering.** vxlan prints its bool options through `print_bool_opt`, `no<key>` in text, using the JSON key (`noudp_csum`), shown only when the value isn't its default, or always at `-d -d`; JSON always has them. vxlan hides a zero v4 group or local; geneve prints its v4 local even at `0.0.0.0` and hides a multicast `remote6`. Both print `ttl auto` and `tos inherit` in text and the number in JSON, and `df unset` in JSON alone. vxlan's and amt's `dev` is `ll_index_to_name`, which sends a get. bareudp prints its ethertype through `ll_proto_n2a` (`[4660]` for an unnamed one), and gtp prints its role by name (`unknown` past sgsn). amt prints its mode from a two-name table, and reads past it for a mode above relay.
+
+**Exit statuses.** KG0's decision holds: `invarg`, `duparg`, `missarg`, `incomplete_command` and `NEXT_ARG` wrap `ErrLinkUsage` (255), and the returned refusals are `ErrInvalidArgument` (1). The two that are neither are `get_addr`'s `exit(1)` (1) and a kind's `dev` `exit(nodev)` (255), which is a new `nodevExitErr`. goip prints a refusal's first line and no usage. amt's bad mode is the exception, as macvlan's bad op was: its first line is the usage line, so goip prints that line.
+
+**goip makes `ip`'s checks itself.** The KP3 encoders refuse the same cases with three errors (`ErrKindSettingConflict`, `ErrKindSettingMissing`, `ErrKindSettingRange`), while `ip` has a text for each. So each parser runs `ip`'s after-loop checks in `ip`'s order and returns `ip`'s text, and the encoder's refusals are a backstop that no goip argv reaches.
+
+#### KG3-T01 The vxlan words
+
+**Code.**
+- **The words.** `internal/goip/link_vxlan_args.go`: `parseVxlanArgs(errOut io.Writer, family uint8, set bool, args []string, resolve linkResolver) ([]xtcpnl.VxlanSetting, error)`, `vxlan_parse_opt`'s chain in its order. It keeps the duparg mask, the two addresses' families for `get_addr` (`routeGetAddr`), and the in-loop checks. `dev` resolves through `resolve` as the word is read. The after-loop checks run in `ip`'s order and the warning goes to `errOut`. The loop walks a shrinking sub-slice, as `parseVlanArgs` does.
+- **The default group.** `xtcpnl.VxlanOptionDefaultGroup`, whose Value is `AF_INET` or `AF_INET6`. `EncodeVxlanInfoData` sends it in the group's place when no local, group or remote was given, and drops it otherwise. `parseVxlanArgs` appends it for `-4` or `-6`. `kindData` gains the `family` `buildLinkWrite` already has.
+- **The helpers.** `nodevExitErr` (255) next to `nodevErr`, and `kindUnknownErr(kind, word)` for `<kind>: unknown command "<word>"?`, which KG3-T02 and KG3-T03 share. A `kindVxlanCst` case in `kindData`.
+
+`TestLinkVxlanWriteMatchesIp` replays `kinds/vxlan/*` through `newLinkReplay` with `useLLMap720`. goip must send `ip`'s lookups and write `ip`'s request, byte for byte with seq and pid zeroed, and exit 0.

+
+### KG4 — goip IP tunnels
+
+Nine tasks:
+- KG4-T01 has the goip-parity driver set `fb_tunnels_only_for_init_net=2` before its first row.
+- KG4-T02 adds the set prefetch every tunnel parser but xfrm's shares, and the gre, gretap and erspan words.
+- KG4-T03 adds the ip6gre family's words, KG4-T04 ipip's and sit's, KG4-T05 ip6tnl's, and KG4-T06 vti's, vti6's and xfrm's.
+- KG4-T07 renders the six gre kinds' `-d` output, and KG4-T08 the other six's.
+- KG4-T09 adds the matrix rows and gates them, which closes KG4.
+
+The codec is KP4's (`pkg/xtcpnl/xtcpnl_gre.go`, `xtcpnl_gre6.go`, `xtcpnl_iptun.go`, `xtcpnl_ip6tnl.go`, `xtcpnl_vti.go`, `xtcpnl_xfrm_link.go`). It decodes into `LinkInfo` and encodes every row's `IFLA_INFO_DATA` in `ip`'s attribute order, from a `cur` the prefetch fills. So KG4 is the prefetch, the words, `ip`'s checks and texts, the renderers and the matrix.
+
+**The rows** (`pkg/xtcpnl/testdata/7_3_0/link-write/kinds/`, argv in `kind-write-corpus.exp`). A set row's topology also makes the device it sets, and the `dev d0` rows run on a dummy `d0`:
+
+| kind | rows | rc 0 | rc 2 (kernel) | rc 1 / 255 (`ip`, before the write) | requests |
+|---|---|---|---|---|---|
+| gre | 45 | 24 | 7 | 8 / 6 | 31 |
+| gretap | 11 | 6 | 4 | 1 / 0 | 10 |
+| erspan | 25 | 14 | 5 | 1 / 5 | 19 |

+| ip6gretap | 9 | 6 | 3 | 0 / 0 | 9 |
+| ip6erspan | 19 | 9 | 6 | 1 / 3 | 15 |
+| ipip | 47 | 26 | 8 | 5 / 8 | 34 |
+| sit | 37 | 20 | 6 | 5 / 6 | 26 |
+| ip6tnl | 49 | 29 | 7 | 3 / 10 | 36 |
+| vti | 23 | 11 | 5 | 3 / 4 | 16 |
+| vti6 | 12 | 7 | 2 | 2 / 1 | 9 |
+| xfrm | 23 | 9 | 8 | 2 / 4 | 17 |
+
+**What `ip` does** (`ip/link_gre.c`, `link_gre6.c`, `link_iptnl.c`, `link_ip6tnl.c`, `link_vti.c`, `link_vti6.c`, `link_xfrm.c`, `ip/tunnel.c` and `lib/utils.c` at `v7.2.0`):
+- **The prefetch.** Every parser but xfrm's starts a set by reading the device back.
+  - **When:** with no `NLM_F_CREATE`, so on `set`, `change` and `delete` but not on `add` or `replace`. It runs only when a word follows the kind, since `iplink_modify` calls `parse_opt` only then. It comes after `iplink_parse`'s get of the device by name and before any word is read, so a set whose words `ip` refuses still costs it.
+  - **The request:** `RTM_GETLINK`, `NLM_F_REQUEST` alone, `ifi_family` the preferred family, the device's index, and no attribute. That is 32 bytes, which `xtcpnl.BuildGetLinkByIndexRequest(family, index, 0, seq)` builds; `Service.LinkByIndex`'s 40-byte get with `IFLA_EXT_MASK` is not it.
+  - **What it seeds:** the reply's `IFLA_INFO_DATA`, read by the parser's own attribute ids whatever the reply's kind. It fills the parser's variables, which the KP4 encoders take as `cur`.
+  - **When it fails:** `Failed to get existing tunnel info.`, exit 1, when there is no reply, no `IFLA_LINKINFO` or no `IFLA_INFO_DATA`, or when an endpoint attribute fails `get_addr_rta`. That means a length other than 4 or 16, or 4 or 16 against the parser's family.
+  - **Two `ip` bugs it carries:** gre's, gre6's and iptnl's prefetch sends a named encap port back byte-swapped, and vti's and vti6's keeps only the low byte of `LINK` (`rta_getattr_u8`). The encoders copy both.
+- **Keywords.** No tunnel parser has a `check_duparg`: a repeated word overwrites, and a flag word accumulates.
+  - **gre:** a word is `matches` through `ttl`/`tos`'s aliases, `strcmp` from `noencap` on; its erspan words are erspan's alone.
+  - **gre6:** the first 27 are `matches`, and its erspan words are every gre6 kind's.
+  - **iptnl and ip6tnl:** only `dev` and `dsfield` are `matches`.
+  - **vti:** all are `matches` but `fwmark`.
+  - **xfrm:** `dev` and `if_id` are `matches`, `external` is `strcmp`.
+  - The chain's order decides an abbreviation: `t` is ttl in every chain that has `tos`, and `d` is `dev` before `dsfield`.
+- **Keys** go through `tnl_parse_key`:
+  - A value with a `.` is `get_addr32`'s address, and a failure is `exit(1)` with `Error: an IP address is expected rather than "<v>"`, which has no period.
+  - Any other value is `get_unsigned` in base 0, and a failure is `exit(-1)`, 255, with `invalid value for "<key>": "<v>"; it should be an unsigned integer`, naming the canonical keyword (`i foo` names `ikey`).
+- **Addresses** go through `get_addr` with the kind's fixed family, whatever `-4` or `-6` says. A failure is `exit(1)` with `Error: <family> address is expected rather than "<v>".`
+  - `any`, `all`, `default` and the zero address are not sent, and they overwrite a seeded endpoint.
+  - A multicast address is sent: this is `is_addrtype_inet_not_unspec`, not vxlan's `is_addrtype_inet_not_multi`.
+- **`dev`** resolves in the loop through `ll_name_to_index`, and a name that doesn't resolve is `exit(nodev)`, 255.
+- **An unknown word**, `help` and `""` among them, prints the kind's usage to stderr and returns -1, exit 1. None of these parsers has a `help` word. The usage's first line pads the kind with `%-9s` in gre and gre6 (`Usage: ... gre      \t[ remote ADDR ]`), `%-6s` in iptnl and ip6tnl and `%-4s` in vti, then a tab. xfrm's is `Usage: ... xfrm dev [ PHYS_DEV ] [ if_id IF-ID ]`.
+- **After the loop:**
+  - gre fills a zero `ikey` or `okey` from a multicast remote and refuses a multicast remote with no local (`A broadcast tunnel requires a source address.`, 1). It does this before `external`, on the seeded endpoints.
+  - iptnl refuses a nonzero ttl with `nopmtudisc` (`ttl != 0 and nopmtudisc are incompatible`, 255, no `Error:`), also on the seeded values, before `external`.
+  - xfrm refuses `external` with an `if_id` or `dev` (1), then a missing `if_id` (`missarg`, 255).
+  - gre6, ip6tnl and vti check nothing.
+- **What is sent.** `external` sends `COLLECT_METADATA` alone (iptnl and ip6tnl put `PROTO` first). Otherwise every parser sends its full set from defaults, the seed and the words. Endpoints go only when not unspec, and `LINK` only when nonzero. xfrm sends each `IF_ID` in the loop, `LINK` after it, and nothing it wasn't given.
+- **Rendering.**
+  - **Endpoints:** `remote` and `local` always print through `tnl_print_endpoint`: `any` when absent or zero, and `unknown` for a wrong length or family.
+  - **Lower device:** `dev` prints when `LINK` is nonzero, through `ll_index_to_name`. The `@d0` lookup has already cached the name, so it costs no get.
+  - **Keys:** each prints dotted, under its `KEY` flag in gre and gre6 and when nonzero in vti.
+  - **ttl, tos and the other inherits:** the ttl is `ttl inherit` (`hoplimit inherit` in gre6 and ip6tnl) in text and 0 in JSON, whose key is always `ttl`. The tos is `tos inherit` in text and `"0x1"` in JSON. gre6 and ip6tnl print their inherit flags by name in text and as `ip6_tnl_f_*` bools in JSON.
+  - **Encap:** `tnl_print_encap` prints the encap words, `encap-csum6` included, which is not a word the parsers take.
+  - **xfrm:** prints `external` and stops, or `if_id`; never its `link`.
+
+**Exit statuses.** KG3's mapping holds:
+- `invarg`, `missarg`, `NEXT_ARG`, `exit(nodev)` and `tnl_parse_key`'s numeric failure wrap `ErrLinkUsage` (255).
+- The returned refusals (the usage line, the prefetch's failure, gre's broadcast check and xfrm's conflict) and `get_addr`'s and `get_addr32`'s `exit(1)` are `ErrInvalidArgument` (1).
+- goip prints a refusal's first line. An unknown word's first line is the usage line, as amt's bad mode was, so `help` prints it too: unlike KG3's kinds, these have no `help` word to refuse as not implemented.
+
+**goip makes `ip`'s checks itself,** as in KG3, and the seeded checks need `cur`, so gre's and iptnl's parsers take it. Five cases are not implemented:
+- sit's `6rd-reset`, on which `ip` 7.2.0 segfaults;
+- ip6tnl's `encaplimit` with a value that isn't a u8, on which `ip` sends an uninitialized byte;
+- sit's `6rd-prefix any` and `6rd-relay_prefix any`, which `ip` sends as an empty address that no `IptunSetting` holds;
+- a prefetch whose reply passes the endpoint checks but is outside the parser's kinds, which `ip` reads by the wrong ids.
+
+#### KG4-T01 No fallback tunnels in goip-parity
+
+**The gap.** `nltopo::late_setup` sets `net.core.fb_tunnels_only_for_init_net=2` and loads the late modules, but goip-parity calls it only at the first row that isn't `route`.
+- **In a section run:** in `--section link` no such row runs, so the sysctl is never set.
+- **In a full run:** it runs at `tcp_metrics`, after every link row.
+- **The effect:** the first row of each tunnel kind autoloads its module, and every namespace made after that holds the fallbacks: gre0, gretap0, erspan0, tunl0, sit0, ip6tnl0, ip6gre0, ip_vti0 and ip6_vti0.
+  - Ifindexes shift between legs on the loading row.
+  - The fallback is an any/any tunnel, so `vti/add_no_option` and the bare-tunnel setups get `-EEXIST`.
+
+**Code.**
+- `netlink-topology.exp`: `nltopo::no_fallback_tunnels subdir`, the sysctl step moved out of `late_setup`, which now calls it first. It returns its problems as `late_setup` does.
+- `goip-parity.exp` calls it after `nltopo::build_clean` and before `foreach row $table`, outside any section test. Its problems are reported at the end as `GOIP_PARITY_EARLY_SETUP_PROBLEMS`, beside `late_problems`, and are never fatal.
+- No current row loads a module that makes a fallback, and the sysctl acts only when a namespace is made, so no committed capture changes.

+
+#### KG4-T02 The prefetch, and the gre, gretap and erspan words
+
+**Code.**
+- **The prefetch.** `internal/goip/link_tunnel_args.go`:
+  - `Service.LinkInfoDataByIndex(family uint8, index int32)` sends `BuildGetLinkByIndexRequest(family, index, 0, seq)` through `singleGet` and returns the reply's kind and its raw `IFLA_INFO_DATA`, with whether `IFLA_LINKINFO` and `IFLA_INFO_DATA` were there.
+  - `tunnelPrefetch(kinds, family, endpoint ids)` refuses each `get_failed` case with `Failed to get existing tunnel info.` (1), checking each endpoint attribute's raw length as `get_addr_rta` does. A reply whose kind is outside `kinds` is refused as not implemented once the endpoints pass.
+  - `kindData` takes a `kindEnv` (errOut, verb, family, the set's index, the resolver and the fetcher) in place of its loose parameters. A tunnel case prefetches when `!verb.create()`, before its words, so `delete` prefetches too.
+- **The shared words:**
+  - `tnlParseKey(name, v)`, with its two statuses;
+  - `tunnelUsageErr(line)`, the usage line at 1;
+  - the encap words and their invarg texts;
+  - `tunnelU8(v, text)` for the ttls, whose texts differ by file.
+
+  `kindTTL`, `kindLabel` and `kindAttrs`' duparg mask are not reused.
+- **The words.** `link_gre_args.go`: `parseGreArgs(kind string, cur *xtcpnl.GreInfo, args []string, resolve linkResolver) ([]xtcpnl.GreSetting, error)`, `gre_parse_opt`'s chain in its order. It holds the erspan words for erspan alone, and gre's multicast check runs on `cur` and the words. `kindGreCst`, `kindGretapCst` and `kindErspanCst` cases call `EncodeGreInfoData(settings, cur, kind == kindErspanCst)`.

+  - 16 vti, 9 vti6 and 17 xfrm.
+
+  Argv is as the corpus ran it. `Floor` is the row's `ip.pcap` record count, which counts the prefetch (6 for a set with words, 8 for `gre/set_dev` and `ipip/set_dev`), and `Setup` is its `topology`. A rc 2 row's comment is its `ip.err`'s last line.
+- **Respellings:** three pairs share an argv, so one of each takes `iplink_parse`'s optional `dev`:
+  - `ip6gretap/add_beside_ip6gre` becomes `link add dev gt6 type ip6gretap remote 2001:db8::1`;
+  - `ip6tnl/set_collide` becomes `link set dev t6 type ip6tnl remote 2001:db8::2`;

+
+### KG5 — goip, the remaining kinds
+
+Seven tasks:
+- KG5-T01 sends the kinds `ip` has no parser for (ifb, nlmon, vcan, team, team_slave, vrf_slave) through dummy's else arm, and adds `iplink_parse`'s `vrf` and `numtxqueues`/`numrxqueues` keywords.
+- KG5-T02 adds the hsr words, KG5-T03 netkit's, and KG5-T04 vrf's, vxcan's and batadv's.
+- KG5-T05 moves the bond parsers' `invarg` and `NEXT_ARG` refusals to 255, which KG0 left for KG5.
+- KG5-T06 renders hsr's and netkit's `-d` output.
+- KG5-T07 adds the matrix rows and gates them, which closes KG5 and the plan's goip phases.
+
+The codec is KP5's (`pkg/xtcpnl/xtcpnl_hsr.go`, `xtcpnl_netkit.go`, `xtcpnl_vrf.go`, `xtcpnl_vxcan.go`, `xtcpnl_batadv.go`). Each encoder takes its words in `ip`'s order and refuses what `ip` can't send. So KG5 is the words, `ip`'s checks and texts, two link keywords, two renderers and the matrix.
+
+**Where goip stands.** A replay of every KC6 row that sent a request through `replayKindRow` with `useLLMap720` (a throwaway test, not committed) finds:
+- 54 of the 122 already match, lookups included: every row of a kind with no words, a set of only `type K`, and the `master`/`nomaster`/`mtu` rows.
+- The other 68 stop at `kindData`'s default arm, or at the `vrf` and `numtxqueues` keywords (`linkArmUnsupported`).
+- Of the 59 rows `ip` refuses, 3 already match: the two missing-master rows and `batadv/set_nodev`.
+
+**The rows** (`pkg/xtcpnl/testdata/7_3_0/link-write/kinds/`, argv in `kind-write-corpus.exp`). A set row's topology also makes the device it sets:
+
+| kind | rows | rc 0 | rc 2 (kernel) | rc 1 / 255 (`ip`, before the write) | requests | already match |
+|---|---|---|---|---|---|---|
+| hsr | 29 | 10 | 10 | 4 / 5 | 20 | 2 |

+**What `ip` does** (`ip/iplink_hsr.c`, `iplink_netkit.c`, `iplink_vrf.c`, `iplink_vxcan.c`, `iplink_batadv.c`, `iplink.c` and `iplink_vrf.c`'s `name_is_vrf` at `v7.2.0`):
+- **No parser.** ifb, nlmon, vcan, team, team_slave and vrf_slave have a `link_util` with no `parse_opt`. A word after `type K` takes `iplink_modify`'s else arm:
+  - a prefix of `help` calls `usage()`, which exits 255 after the whole `ip link` usage;
+  - any other word is `Garbage instead of arguments "<w> ...". Try "ip link help".`, exit 1.
+
+  So `type ifb mtu 1400` is refused: `iplink_parse` stops at `type`.
+- **`vrf NAME`** (`iplink_parse`, `strcmp`) runs `ll_name_to_index` (`ll_link_get`, the 7.2.0 mask with `RTEXT_FILTER_NAME_ONLY`), then `name_is_vrf`, a get by name with no `IFLA_EXT_MASK` whose `IFLA_INFO_KIND` must be `vrf`. Either failing is `invarg("Not a valid VRF name\n")`, 255. It sends `IFLA_MASTER`, as `master` does. goip's nexthop code already has the second get (`Service.IsVRF`).
+- **`numtxqueues N` and `numrxqueues N`** (`matches`): `get_integer` in base 0, so a negative number passes and goes out as its u32. A bad value is `invarg("Invalid \"numtxqueues\" value\n")`, 255, and a second one is `duparg`, 255. They send `IFLA_NUM_TX_QUEUES` (31) and `IFLA_NUM_RX_QUEUES` (32), u32, in word order.
+- **hsr.**
+  - `supervision`, `version`, `proto`, `slave1` and `slave2` are `matches` in that order, so `s` is supervision and `sl` is slave1; `interlink` is `strcmp`; `help` is `matches`, after the others.
+  - Each word sends its attribute as it is read, so a repeat sends twice.
+  - `supervision` is `get_u8` in base 0 (`ADDR-BYTE is invalid`). `version` and `proto` test `get_u8`'s return rather than the value, so any u8 passes (`version is invalid`, `protocol is invalid`). These are `invarg`s, 255.
+  - `slave1`, `slave2` and `interlink` resolve through `ll_name_to_index` in the loop: a get each, then `invarg("No such interface")`, 255.
+  - `help` prints the usage and an unknown word prints `hsr: what is "<w>"?` and the usage; both exit 1.
+- **netkit.**
+  - Every word is `strcmp`. `mode` takes `l3` or `l2`; another value is `Error: argument of "mode" must be either "l3" or "l2"`, 1, and a second `mode` is `duparg`, 255.
+  - `forward` and `blackhole` send `POLICY`, or `PEER_POLICY` after `peer`.
+  - `scrub` takes `none` or `default` (`Error: scrub must be either "none" or "default"`, 1) and sends `SCRUB`, or `PEER_SCRUB` after `peer`.
+  - A second `peer` is `duparg("peer", *(argv + 1))`, which prints `(null)` at the end of the line.
+  - After `peer`, any other word starts `iplink_parse` into `PEER_INFO`, over the rest of the line. `ip` first saves the device's `ifi_flags`, `ifi_change` and `ifi_index` and zeroes them, then copies what `iplink_parse` left there into the peer's header and restores its own. A `type` in the peer is `duparg("type", argv[err])`, which prints `(null)`.
+  - So `peer black` makes a peer named `black`, and `peer name nt1 blackhole` is `iplink_parse`'s `both "name" and "dev" cannot be used when creating devices.`, 255.
+  - Before `peer`, an unknown word, `help` among them, is `netkit: unknown option "<w>"?` and the usage, 1.
+- **vrf.** `table` (`matches`) goes through `rtnl_rttable_a2n`: a name from `rt_tables` or `get_u32` in base 0. A failure is `invarg("invalid table ID\n")`, 255. `help` prints `Usage: ... vrf table TABLEID`, and an unknown word prints `vrf: unknown option "<w>"?` and the usage; both 1. Each `table` sends `IFLA_VRF_TABLE`, repeats included.
+- **vxcan** is veth's parser with `VXCAN_INFO_PEER`:
+  - the first word must be `peer` (`strcmp`), else the usage goes to stdout, not stderr, and `ip` exits 1;
+  - `iplink_parse` reads the rest into the peer, with veth's header swap;
+  - a `type` in the peer is `duparg("type", argv[err])`, whose index is one short, so it prints the peer's kind value (`"vxcan"`).
+- **batadv.** `ra` (`matches`, so `r` is `ra`) sends its value as `IFLA_BATADV_ALGO_NAME` with its NUL (`addattrstrz`), unchecked, repeats included. `help` and an unknown word (`batadv: unknown command "<w>"?`) print the usage, 1.
+- **Rendering.** vrf, vrf_slave, vxcan, batadv and the no-parser kinds already render: a throwaway replay of every accepted row's `-d` and `-d -j` matches its readbacks.
+  - **hsr** returns before printing anything if `SLAVE1`, `SLAVE2` or `INTERLINK` is under 4 bytes, `SEQ_NR` under 2 or `SUPERVISION_ADDR` under 6. Otherwise:
+    - `slave1 <name> ` and `slave2 <name> ` through `ll_index_to_name`, or `<none>` (JSON `null`) when absent;
+    - `interlink <name> `;
+    - `sequence %d ` (JSON `seq_nr`);
+    - `supervision <mac> ` (JSON `supervision_addr`);
+    - `proto %hhu ` and `version %hhu `.
+  - **netkit** prints `mode`, then `type primary` or `type peer` from `PRIMARY`, then `policy`, `peer policy`, `scrub` and `peer scrub` (JSON `peer_policy`, `peer_scrub`). A value outside its table is `UNKNOWN`.
+
+**Exit statuses.** KG3's mapping holds:
+- `invarg`, `duparg`, `NEXT_ARG`'s `incomplete_command`, and `usage()` for a no-parser kind's `help` would wrap `ErrLinkUsage` (255).
+- A parser's returned -1 is `ErrInvalidArgument` (1). That covers its unknown word, its own `help`, netkit's mode and scrub texts, vxcan's missing `peer`, and the Garbage line.
+
+**Decisions this phase makes** (the decision log gets each):
+- **hsr's `version` and `proto`: goip copies the check as written.** Any u8 is sent, and `version 2` is the kernel's refusal, not goip's. KP5's encoder already takes any u8.
+- **sit's `6rd-reset` stays `ErrNotImplemented`** (KG4-T04). `ip` crashes on it, so there is no `ip` behavior to match.
+- **The help rows that print `ip link`'s whole usage stay `ErrNotImplemented`,** as dummy's `help` and `ip link help` are. Four rows: `ifb/add_help_abbrev`, `team/add_help`, `netkit/add_peer_help` and `vxcan/add_peer_help`.
+- **vxcan's usage goes to stderr in goip.** goip prints every refusal as `goip: <text>` on stderr, and the status (1) matches. `vxcan/add_abbrev`, `add_help` and `add_unknown` have an empty `ip.err`, so their table rows check the text against `ip.out`.
+
+#### KG5-T01 The kinds with no parser, and the vrf and queue keywords
+
+**Code.**
+- `internal/goip/link_write.go`:
+  - `kindData`'s dummy case becomes `kindNoParserCst`'s set: dummy, ifb, nlmon, vcan, team, team_slave and vrf_slave. The text and status don't change.
+  - The `kind*Cst` names go with the others.
+- `internal/goip/link_args.go`:
+  - `vrf` gets an arm. It resolves the name through the resolver, then calls a `vrfCheck` that `buildLinkWrite` takes beside `resolve`, `Service.IsVRF` in `linkWrite`. Either failing is `Error: argument "<v>" is wrong: Not a valid VRF name`, 255. The arm sends `IFLA_MASTER`.
+  - `numtxqueues` and `numrxqueues` get an arm each: `matches`, `strconv.ParseInt(v, 0, 32)`, and a negative value sent as its u32. A failure is `invarg`, 255; a second use is `duparg`, 255.
+

+
+**Mutation check:**
+- vrf_slave left out of the set (`vrf_slave/set_type_word`);

+#### KG5-T02 The hsr words
+
+**Code.** `internal/goip/link_hsr_args.go`:
+- `parseHsrArgs(args []string, resolve linkResolver) ([]xtcpnl.HsrSetting, error)` is `hsr_parse_opt`'s chain in its order, each slave resolved as it is read.
+- The `kindHsrCst` case calls `EncodeHsrInfoData`. The usage line is `Usage:\tip link add name NAME type hsr slave1 SLAVE1-IF slave2 SLAVE2-IF`, with its tab.
+
+`TestLinkHsrWriteMatchesIp` replays the 20 request rows:

+
+**Done when:** as KG5-T01.
+
+#### KG5-T03 The netkit words
+
+**Code.** `internal/goip/link_netkit_args.go`:
+- `netkitData(env, rest)` is `netkit_parse_opt`. It builds `[]xtcpnl.NetkitSetting` and, after `peer` and a word that isn't netkit's, runs `parseLinkArgs(rest[i:], verb.create(), resolve)` for the peer, as `vethData` does.
+- It refuses the peer's `type` with `duparg("type", "(null)")` and a second `peer` with `duparg("peer", next)`, where `next` is `(null)` at the end of the line.
+- It then calls `EncodeNetkitInfoData(settings, peer)`, the peer nil when no word followed `peer`.
+
+`TestLinkNetkitWriteMatchesIp` replays the 27 request rows:

+
+#### KG5-T04 The vrf, vxcan and batadv words
+
+**Code.**
+- `internal/goip/link_vrf_args.go`: `parseVrfArgs(args)` is `vrf_parse_opt`. `table` goes through goip's `rtnl_rttable_a2n`, `routeTableNames` and then `get_u32`, factored out of `routeParseState.table` (`route_write.go:434`). The case calls `EncodeVrfInfoData`.
+- `link_write.go`: the `kindVxcanCst` case is `vethData` with a kind argument. That gives vxcan `ip`'s usage line, `Usage: ip link <options> type vxcan [peer <options>]`, and `EncodeVxcanInfoData`. veth keeps its own text.
+- `internal/goip/link_batadv_args.go`: `parseBatadvArgs(args)` is `batadv_parse_opt`, and the case calls `EncodeBatadvInfoData`.

+
+**The gap.** `ip`'s `bond_parse_opt` and `bond_slave_parse_opt` exit 255 on `invarg` and on `NEXT_ARG`'s incomplete line. goip's bond parsers return `ErrInvalidArgument`, 1, because KG0-T01 left them for KG5. The rest stay 1, as in `ip`:
+- the unknown word;
+- `nodev` for `primary` and `active_slave`;

+- `parse_on_off`;
+- `get_addr32`'s and `get_addr`'s `exit(1)`.

+
+**Code.**
+- `internal/goip/render/link_hsr.go`: `hsrData(h *xtcpnl.HsrInfo, names NameTab)`, which is `hsr_print_opt`. The decoder keeps each attribute's raw length, so the short-payload return can be checked.
+- `link_netkit.go`: `netkitData(n *xtcpnl.NetkitInfo)`.

+
+**Done when:** as KG5-T01.
+
+#### KG5-T07 The remaining kinds' matrix rows
+
+**Rows.** In `internal/goipparity/commands.go`, after the IP tunnel rows:
+- **Write rows**, slug `link_<kind>_<slug>`, one per corpus row that sent a request, 122 in all: 20 hsr, 27 netkit, 12 vrf, 7 vrf_slave, 9 vxcan, 12 batadv, 5 ifb, 5 nlmon, 11 vcan, 11 team and 3 team_slave.
+  - Argv is as the corpus ran it. `Floor` is the row's `ip.pcap` record count, and `Setup` is its `topology`. A rc 2 row's comment is its `ip.err`'s last line.
+- **Respellings:** six pairs share an argv, so one of each takes `iplink_parse`'s optional `dev`:
+  - `batadv/add_duplicate` becomes `link add dev bat0 type batadv`;
+  - `vrf/add_shared_table` becomes `link add dev vr0 type vrf table 10`;
+  - `team/set_enslave_again` becomes `link set dev d0 master tm0`;
+  - `vrf_slave/set_nomaster` becomes `link set dev d0 nomaster`;
+  - `team_slave/set_unenslaved` becomes `link set dev d0 type team_slave`;
+  - `vcan/set_mtu_up` becomes `link set dev vn0 mtu 72`.
+- `kindRowKinds` gets the eleven kinds.
+- **Read rows:** `-d link show dev <dev>` and `-d -j …` for each kind, 22 in all. Each device's setup and command come from one accepted corpus row of its kind, and its floor is that row's `netlink_route_getlink_detail.pcap` record count.
+- **Modules.** Each kind's first row autoloads its module, as KC6's capture did.
+  - If a module's first load makes a leg differ, as ifb's two default devices or a fallback could, the module goes into `nltopo::late_modules`.
+  - The first VM run decides, and the decision log records it.
+
+`TestRemainingKindsMatrixRows` (`internal/goipparity/commands_kinds_test.go`):
+
+| description | input | expected |

+| positive: one write row per request row | the eleven kinds' slugs | the corpus's rows with `ip.rc` 0 or 2: 122 |
+| negative: no `ip`-refused row | the 59 rows with `ip.rc` 1 or 255 | absent |

+
+`TestCompareWriteRow`'s every-write-row case runs the 122 on their own corpus captures, and the 144 go in `TestAllowlistCommitted`'s earned list.
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: two consecutive clean section runs | `goip-parity -- --timeout 12000 --section link`, twice | the 144 rows `PASS` on both, and every gated `link` row still `PASS` |
+| corner: the kernel-refused rows compare on the request | the 46 rc 2 rows | `PASS` |
+| corner: a module's first load | the first ifb, team, hsr and batadv rows | `PASS` on all three legs |
+
+Then the 144 rows go in `gated_commands`. A full run comes before the next push.
+
+**Mutation check:**
+- `vrf_slave/set_vrf`'s floor as 6 (its corner row);
+- a setup step dropped (the setup row);
+- a row dropped (the request-row row);
+- an `ip`-refused row added (the negative row);
+- `vcan/set_mtu_up` back to its corpus spelling (the unique row);
+- a read row's floor short by 2 (the read row);
+- a row dropped from `gated_commands` (the gated row and `TestUngatedSurfaceIsNotVacuous`).
+
+**Done when:** the offline tables pass; the two VM runs are clean; the rows are gated; lint-baseline passes. It closes KG5.

+# goip ↔ `ip` live forms: implementation status
+
+**Last updated:** 2026-11-03
+
+**Summary:**
+- The design and the task plan are in [goip-live-forms.md](goip-live-forms.md). This document tracks progress against them.
+- The plan is written (DOC001). It follows [goip-write-keywords.md](goip-write-keywords.md), whose GW1 to GW5 are done ([its status](goip-write-keywords-status.md), DOC006). The 22 forms GW5 left with no live row get a `kwlive` workbench family of 27 rows with an `ip`-only setup, then goip-parity rows and a VM gate.
+
+- LF1-T01 is done: `nlcapgen matrix -family kwlive` writes 36 rows, the 27 forms (23 rc 0, 4 rc 2) and 9 duplicate adds, to `nix/microvms/workbench/kwlive.rows.jsonl` (V001–V003).
+- **LF1 is closed.**
+
+- LF2-T01 is done: two fresh-boot batches give 36 of 36 rows `OK` each, with every rc as the generator wrote it and the same rc and message types row for row; the first batch's captures are in `ws/kw*/`, and `TestWsCorpusRows` passes over them (V004–V006).
+- LF2-T02 is done: `TestWsKwliveCorpus` checks each of the 36 rows' one request against its axes (`kwliveProblem`), and every form sends what the forms table says. `TestKwliveProblem`'s 34 hand-built rows hold each check, and its negative rows fail (V007–V009).
+- LF2-T03 is done: O5 reads the five `kwlive` spaces, and all 36 rows are `same`. Four `kwnh` rows first differed: `ip` sends stack bytes in a nexthop's MPLS encap padding, which O5 now zeroes before comparing, as it does `RTA_METRICS`' (V010–V012).
+- **LF2 is closed.**
+
+- LF3-T01 is done: 23 `gw_kw*` goip-parity write rows, one per form and ip rc, picked by the GW5 tables from the `kwlive` rows; every form GW5 left with no row has one at rc 0, and `tos`, `dsfield`, `pref`, `index` and single-nexthop `hw_stats off` one at rc 2 as well. They stay ungated until LF3-T02 (V013–V015).
+- LF3-T02 is done. The first `--section route,link,nexthop,rule` run passed 926 of 927 rows; `gw_kwnh_ec_003` diverged on the three pad bytes after `MPLS_IPTUNNEL_TTL` that `ip` takes from its stack (V016). nlparity now compares an `NLA_F_NESTED` attribute past its inner padding, as it already did a top-level attribute (V017, V018). On that, the section run passes 927 of 927 and the full run, with the 23 rows gated, 1304 of 1304 (V019, V020); the rows are in `gated_commands` (V021).
+- **LF3 is closed, and with it the plan.**
+
+**Next action:** none in this plan. The ip→goip work continues in [goip-lwt-encap.md](goip-lwt-encap.md) ([its status](goip-lwt-encap-status.md)). The next push needs the whole-repo `test-go-race` check, a clean full VM run and an explicit OK.

+- States are `not started`, `in progress`, `blocked`, `done` or `deferred`. There are no percentages.
+- A task is `done` only when its "Done when" has passed and the evidence is in the [ledger](#verification-ledger).
+- Evidence IDs (`V###` for code and VM runs, `DOC###` for docs) are immutable and append-only.
+- Task IDs (`LFn-Tmm`) are never renumbered.

With `wsO5ZeroEncapPad` the golden gains the five spaces (13, 9, 5, 8 and 1 `same`, 0 otherwise) and `# encap padding: 4 rows`; every other space's line is unchanged, and the lookup notes are the known `IFLA_EXT_MASK` alone | 1332e184 |

The three forms tables read the `kwlive` spaces too: the 20 forms with no row now pick 23 `kwlive` rows (13 route, 4 link, 5 nexthop, 1 rule); the two-hop form's rc 0 moves from `route4/pw-004` to `kwroute4/ec-007`, and `pw-004` stays as the weights form's.

+
+## Decision log
+
+- **New rows rather than a wider setup rule.** The selftest rows' `sysctl` steps don't change the forms' requests, but goip-parity runs Setup through `ip` on each side, so a `sysctl` step can't be a Setup step. Rows of our own with an `ip`-only setup reach the same forms without a second tool in the comparison.
+- **`xdpoffload off` is rc 0 and an `index` in use `EEXIST`, not the plan's rc 2 and `EBUSY`.** `dev_xdp_attach` calls the driver only when the program changes, and a detach with none attached doesn't; `rtnl_newlink` finds `lo` by index 1 and the add's `NLM_F_EXCL` refuses it. The plan's forms table is corrected; LF2-T01's capture is the check.
+- **Up to three duplicates per space, not one per add.** `deriveDupGone`'s limit, as the other spaces; GW5's selection passes duplicates over anyway, so more would add capture time and nothing to the matrix.
+- **`xdpoffload off`'s flags are the axis and `XDP_FLAGS_UPDATE_IF_NOEXIST`.** The row's `xdp_flags` 8 is the mode; `xdp_parse` adds `UPDATE_IF_NOEXIST` unless `-force`, so the request sends 9 and O3 expects it.
+- **O5 zeroes `ip`'s encap padding rather than calling the rows `differs`.** `ipnexthop_modify` hands `lwt_parse_encap` an uninitialized `char buf[1024]` (`ip/ipnexthop.c:1102`) and copies it with `addraw_l`; `rta_addattr_l` doesn't clear alignment padding, so the bytes are whatever was on the stack. The kernel ignores padding, so they aren't part of the request's meaning; goip writes zeros. It is the `RTA_METRICS` case again (`wsO5ZeroMetricsPad`), and gets its own count line so neither hides the other. Not reported upstream from here.
+- **The `kwlive` rows are the last route rows.** The first `encap mpls` request autoloads `mpls_router` and `mpls_iptunnel` (`lwtunnel_valid_encap_type`'s `request_module`), and `mpls_router` adds AF_MPLS to an AF_UNSPEC `netconf show` and to `afstats`. Every row after the block is generic netlink or XFRM, so no row reads a reply the modules changed.
+- **The vrf forms name their VRF.** Both vrf rows' setup makes `vrf0` (table 100) and `vrf1` (table 1111), so a pre pattern on the table alone matched both; each form now matches `vrf vrfN` in the cmd and `vrfN type vrf table` in the pre.
+- **The one-label MPLS form excludes `ttl`.** `\bencap mpls \d+ ` matched the ttl row's duplicate at rc 2, whose argv then barred `kwnh/ec-003` from the ttl form; the form is now `\bencap mpls \d+ via `.
+- **`kwroute6/dup-2` is the `pref` form's rc 2 row.** GW5's rule passes a duplicate over only where a pick has its argv; `pref 2`'s add isn't a pick, so its duplicate is a row, as `route6/gone-3` was.
+- **nlparity compares a nest past its padding, rather than holding `gw_kwnh_ec_003` back.** V016 is the watched divergence: `ip`'s three bytes after `MPLS_IPTUNNEL_TTL` are its stack's. A top-level attribute's value already stops at `nla_len`, so its padding never reached a comparison; inside an `NLA_F_NESTED` attribute the payload was one value, padding and all. `samePastPadding` makes the two agree: two nested payloads that parse to the end into the same attributes, in the same order, with the same types and values (descending into inner nests), are the same. Anything else is still the one value finding it was. Only flagged nests: `IFLA_AF_SPEC` and the other unflagged nests stay compared whole. An allowlist entry would instead have suppressed any value difference in `NHA_ENCAP`.
+- **Watch `kwnh/ec-003` in the VM.** nlparity compared `NHA_ENCAP` as one value, padding inside it included, and the workbench's `ip` put `7f 00 00` after `MPLS_IPTUNNEL_TTL`. The VM's did too (V016); the decision above settles it.
+- **A separate family.** Adding the forms as axis values to `route`, `link`, `nexthop` or `rule` would change those spaces' pairwise rows and force a recapture of every row in them. `kwlive` leaves them byte for byte.

+# goip ↔ `ip` parity: live rows for the keyword forms only O5 checks
+
+## Status
+
+**Last updated:** 2026-11-03
+
+**Summary:**
+- [goip-write-keywords.md](goip-write-keywords.md) is finished. Its GW5 put a goip-parity row in the VM matrix for each keyword form GW1 to GW4 built, taking the first workbench row whose setup is `ip` alone.
+- 22 forms got no such row. The O5 differential and the unit tables still check them offline, but nothing runs them through `ip` and goip side by side on a live kernel. These are the forms GW5's ledger lists (goip-write-keywords-status.md V049, V052, V055):
+  - **every corpus row's setup also runs `sysctl`:** route `pref` by number, `dsfield`, both `vrf` table forms; nexthop `encap mpls` (one label, an IPv6 gateway);
+  - **no corpus row at all:** route `tos`, `realms` `TO` and `FROM/TO`, a hop's `onlink`, a hop `via inet6` on IPv4, a hop's `realms`; link set by `group` alone, `xdpoffload`, `index` on a create; nexthop `encap mpls` with two labels or a `ttl`, `hw_stats off` on a single nexthop; rule `realms` `FROM/TO`.
+- The `sysctl` steps those selftest rows run (`rp_filter`, forwarding, `accept_dad`) change nothing in the requests the forms send. So this plan doesn't widen the matrix's setup rule. It adds workbench rows, with an `ip`-only setup, for exactly these forms. GW5's selection then picks them like any other row.
+
+**Progress** is tracked in [goip-live-forms-status.md](goip-live-forms-status.md).

+
+## Reference sources
+
+- **`ip` is 7.2.0** and the guest kernel 7.3.0, as in [goip-write-keywords.md](goip-write-keywords.md#reference-sources).
+- **The generator** is `tools/nlcapgen` (`nlcapgen matrix -family F`), whose spaces write `nix/microvms/workbench/F.rows.jsonl`. **The workbench** (`nix run .#nlcap-ws -- up`, then `batch`) captures them into `pkg/xtcpnl/testdata/7_3_0/ws/<space>/<id>/`.
+- **The oracles** are O1/O2 in `pkg/xtcpnl/xtcpnl_ws_corpus_test.go`, a family's O3 in its `xtcpnl_ws_*_test.go`, and O5 in `internal/goip/ws_differential_test.go`.
+- **The selection** is `internal/goipparity/commands_gw_test.go`'s `gwSelect` and its three forms tables.
+
+## The forms
+
+One new family, `kwlive`, in a new `tools/nlcapgen/matrix_kwlive.go`. Each space has two axes, the verb (`add` alone) and the form. Pairwise over two axes gives one positive row per form, and the space's `Derive` adds up to three duplicate adds (rc 2, `EEXIST`) in `kwroute4`, `kwroute6` and `kwnh`, as `deriveDupGone` does for the other spaces. A form the kernel refuses is a bad value on the form axis, so its row is an `ng` row. "rc" is the expectation the generator writes; LF2-T01's first capture confirms or corrects each one, and a correction goes in the decision log.
+
+**The setup.** `kwroute4`, `kwroute6` and `kwnh` take GW5's `d0` setup (the dummy, `addrgenmode none`, up, `192.0.2.10/24`, `2001:db8:1::10/64 nodad`). The route spaces add `vrf0` (table 100) and `vrf1` (table 1111), both up. `kwlink` takes `d0` and `d1` in group 5. `kwrule` needs none. Every step is `ip`.
+
+| space | form | cmd (after `ip`) | rc | sends |

+
+The `kwnh` rows list `mpls_router` and `mpls_iptunnel` in `modules`, which the guest runner loads before the batch.
+
+## Out of scope
+
+- **Widening the matrix's setup rule.** GW5's rule, that a row's setup is `ip` alone, stays. The goip-parity driver runs Setup through `ip` on each side, and a `sysctl` step would be a second tool in the comparison.
+- **New goip code.** Every form is built already. A row that turns out `differs` or `sends` in O5 is a goip bug, fixed in the task that finds it and recorded.
+- **Moving the existing families.** `route`, `link`, `nexthop` and `rule` keep their rows and captures byte for byte; the new rows are a separate family so that no existing row is regenerated.
+
+## Gates every task inherits
+
+[goip-write-keywords.md's gates](goip-write-keywords.md#gates-every-task-inherits), with these for the generator and the workbench:
+- **The rows file is deterministic:** `nlcapgen matrix -family kwlive` writes the committed bytes again.
+- **Capture:** a family is committed only after a second fresh-boot `batch` gives the same rc and message types for every row.
+- **O5:** the new spaces are in `wsO5Spaces`, every new row is `same`, and no existing row's outcome changes.
+
+## Phases and tasks
+
+```text
+LF1 ──> LF2 ──> LF3
+```
+
+Every task's tests are tables: description | input | expected, with positive, negative, boundary and corner rows.
+
+### LF1 — the rows
+
+#### LF1-T01 the `kwlive` family
+
+`tools/nlcapgen/matrix_kwlive.go`: the five spaces, registered in `main.go` as the family `kwlive`, written to `nix/microvms/workbench/kwlive.rows.jsonl`.
+
+`TestKwliveSpaces` (`matrix_kwlive_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: one row per form | `kwlive`'s spaces, `-random 0` | 27 rows from the forms table, each `cmd` as listed, and 9 duplicates |
+| positive: the duplicate adds | `Derive` | three `dup` rows in each of `kwroute4`, `kwroute6` and `kwnh`, rc 2, each a positive's argv |
+| positive: each row's rc | the forms table | each row's `expect.rc` as listed |
+| negative: no setup step is anything but `ip` | every row's `pre` | each step starts `ip ` and tolerates no exit status |
+| boundary: `pref` 255 | `kwroute6` | the row's `axes` has `pref` 255 |
+| corner: the same bytes twice | two runs, seed 1 | identical files |
+| corner: the `kwnh` modules | `kwnh`'s rows | `modules` is `mpls_router`, `mpls_iptunnel` |
+
+**Mutation check:** a form dropped from a space; a setup step given a tolerated exit status; `pref 255` written as `pref 256`.
+
+**Done when:** the table passes, the rows file is committed and regenerates to the same bytes, and lint-baseline passes.
+
+### LF2 — the captures and the oracles
+
+#### LF2-T01 capture
+
+`nix run .#nlcap-ws -- up`, `batch nix/microvms/workbench/kwlive.rows.jsonl`, `down`, `up`, `batch` again, and compare.
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: every row captured | the batch | a `ws/<space>/<id>/` per row with `ip.pcap`, `ip.rc`, `cmd.json` |
+| positive: a second fresh boot agrees | the second batch | the same rc and message types for every row |
+| negative: an rc the generator got wrong | the first batch | the row's expectation corrected in the generator and the decision log |
+| corner: `TestWsCorpusRows` (O1/O2) | the new rows | every row passes |
+
+**Done when:** both batches agree and `TestWsCorpusRows` passes.
+
+#### LF2-T02 O3 for `kwlive`
+
+`pkg/xtcpnl/xtcpnl_ws_kwlive_test.go`: each row's request decoded, and the form's attribute checked against the row's `axes` (the "sends" column).
+
+| description | input | expected |
+|---|---|---|
+| positive: `tos` and `dsfield` | `kwroute4` and `kwroute6`'s rows | `rtm_tos` as the axis |
+| positive: `realms` | the `TO`, `FROM/TO` and hop rows | `RTA_FLOW` (or the hop's) with `FROM` shifted 16 |
+| positive: `vrf` | the four rows | `rtm_table` below 256; `RTA_TABLE` and `rtm_table` 0 above |
+| positive: the hop flags and gateways | `onlink`, `via inet6` | `RTNH_F_ONLINK`; `RTA_VIA` with family 10 |
+| positive: `encap mpls` | the four `kwnh` rows | the label stack, the bottom bit, the `ttl`, the gateway length |
+| positive: the link forms | `kwlink`'s rows | `ifi_index` 0 and `IFLA_GROUP`; `IFLA_XDP` flags; `ifi_index` 77 |
+| negative: a request with the wrong width | a hand-built `RTA_PREF` u32 | the check fails |
+| corner: a row with no request | none expected | the count of such rows is 0 |
+
+**Mutation check:** `FROM` not shifted in the model; `rtm_table` read for a table ≥ 256; the bottom bit ignored.
+
+#### LF2-T03 O5 over `kwlive`
+
+`kwroute4`, `kwroute6`, `kwlink`, `kwnh` and `kwrule` go in `wsO5Spaces`; the golden is regenerated.
+
+| description | input | expected |
+|---|---|---|
+| positive: every new row `same` | `TestWsGoipDifferential` | no new row in `ws-differential.txt` |
+| negative: no existing row moves | the golden's diff | only the summary counts change |
+| corner: a refusal compares at the check | the rc 2 rows | `same` |
+
+**Done when:** O5's golden shows every new row `same`; lint-baseline and netlink-audit pass.
+
+### LF3 — the matrix rows and the VM gate
+
+#### LF3-T01 the rows
+
+The three forms tables in `commands_gw_test.go` gain the new spaces' picks, and each form that had no row names its pick; `commands.go` gains the rows as GW5's (`gw_` slugs, argv, setup and floor from the capture). `gwCorpusDir` already maps a slug back to its `ws/` directory.
+
+| description | input | expected |
+|---|---|---|
+| positive: each form's pick | the forms tables | the `kwlive` row by id for rc 0 and rc 2, where one exists |
+| positive: the rows' floors | the picks' `ip.pcap` | `Floor` equal to the record count |
+| negative: a pick from an old family where `kwlive` has one | the tables | none: the old families had no row for these forms |
+| corner: a `dup` row | the pass-over rule | passed over, as GW5's |
+
+**Mutation check:** as GW5-T01's.
+
+#### LF3-T02 the VM gate
+
+As [GW5-T04](goip-write-keywords.md#gw5-t04-the-vm-gate): a `--section route,link,nexthop,rule` run, then the full run; then the rows are gated.
+
+**Done when:** both runs are clean, the rows are gated, and lint-baseline passes. It closes the plan.

+# goip ↔ `ip` lightweight-tunnel encap: implementation status
+
+**Last updated:** 2026-11-04
+
+**Summary:**
+- The design and the task plan are in [goip-lwt-encap.md](goip-lwt-encap.md). This document tracks progress against them.
+- The plan is written (DOC001). It follows [goip-live-forms.md](goip-live-forms.md), which is closed ([its status](goip-live-forms-status.md)). goip builds `encap` `mpls`, `ip` and `ip6`, with the tunnel options, for a route, a hop and a nexthop object. A 27-form `lwt` workbench family checks it, followed by goip-parity rows and a VM gate.
+
+- LE1-T01 is done: `pkg/xtcpnl/xtcpnl_lwt_ip.go` encodes `encap ip` and `ip6`, with the geneve, vxlan and erspan options. `PutLwtEncap` covers it and `mpls`, and `EncodeLwtEncap` gives a route's or a hop's two `RouteAttr`s. The tunnel flags go out big-endian. `TestPutIPEncap`'s goldens are hand-built from the uapi numbers (V001–V003).
+- LE1-T02 is done, and LE1 is closed: `lwtEncapArgs` in `internal/goip/lwt_encap_args.go` reads `encap mpls`, `ip` and `ip6` as `lwt_parse_encap` does, and the nexthop object's `encap` uses it (`ip`/`ip6` there still refuse until LE2-T02). `dst any` and `dst all` send an empty address, as `get_addr` gives them (V004–V006).
+- LE2-T01 is done: a route's `encap` (`routeArmEncap`) and a hop's (`parseOneNh`) go where the keyword is, from `internal/goip/route_write_encap.go`. ip's two buffer bounds are refusals. O5's two fibt rows moved from `refuses` to `differs`, and the only difference is `ip`'s stack padding after a hop's `RTA_ENCAP_TYPE`, which LE3-T03 zeroes (V007–V009).
+- LE2-T02 is done, and LE2 is closed: a nexthop object's `encap ip` and `ip6` are built, no longer `ErrNotImplemented`, through `EncodeLwtEncapAs` with `NHA_ENCAP` and `NHA_ENCAP_TYPE`, under the same `addraw_l` bound as a route. `mpls`'s rows are unchanged (V010–V012).
+- LE3-T01 is done: `nlcapgen matrix -family lwt` writes 39 rows, the 27 forms (21 rc 0, 2 rc 2, 4 rc 255) and 12 duplicate adds, to `nix/microvms/workbench/lwt.rows.jsonl`. The plan's counts were corrected to these (V013–V015).
+- LE3-T02 is done: two fresh-boot batches agree on all 39 rows, every rc as written, and the first is the corpus in `pkg/xtcpnl/testdata/7_3_0/ws/lwt*` (V016–V018). The runs' only byte differences are `ip`'s unzeroed padding, in three places LE3-T03's O5 zeroing has to reach.
+- LE3-T03 is done, and LE3 is closed. O3 (`pkg/xtcpnl/xtcpnl_ws_lwt_test.go`) checks the 35 captured requests' encaps against their axes, and the 4 rc 255 rows send none. O5 has the four spaces: all 39 rows are `same`, and the two fibt rows moved from `differs` to `same`, now that `wsO5ZeroEncapPad` reaches a route's `RTA_ENCAP`, each hop's in `RTA_MULTIPATH`, and every nest inside them (V019–V021).
+- LE4-T01 is done: 23 `gw_lwt*` goip-parity write rows, one per form and ip rc, picked by `TestGwLwtMatrixRows` from the `lwt` rows: the 21 rc 0 forms, and implicit null and geneve's 3 data bytes at rc 2. nlparity now compares `RTA_MULTIPATH` hop by hop past each hop's padding, since the captures show `ip`'s stack bytes after a hop's `RTA_ENCAP_TYPE`. The rows stay ungated until LE4-T02 (V022–V024).
+- LE4-T02 is done, and LE4 and the plan are closed. The full run on the main merge, 5599e473, was clean (V025). On 84260fe2, two `--section route,nexthop` runs passed 124 of 124, all 23 `gw_lwt*` rows among them (V026). The full run with the rows gated passed 1330 of 1330 (V027). The 23 rows are in `gated_commands` and `TestAllowlistCommitted`'s earned list, and the GW matrix tables' gated check and `TestUngatedSurfaceIsNotVacuous` no longer skip `gw_lwt*` (V028–V029).
+
+**Next action:** none in this plan. The other encap types, all but `bpf`, are planned in [goip-lwt-srv6.md](goip-lwt-srv6.md) and tracked in [its status doc](goip-lwt-srv6-status.md).

+## Decision log
+
+- **`mpls`, `ip` and `ip6` first, with their options.** They're the types goip's corpus already has (`kwnh`, the two fibt rows), and they share one grammar. The others each bring a structure of their own and get a follow-on plan, in the selftests' order of use.
+- **One encoder for three places.** A route's, a hop's and a nexthop's encap are the same `lwt_parse_encap` writing to different attribute types. A single `lwtEncapArgs` keeps their parsing identical, as `ip`'s is.
+- **goip refuses an encap over `ip`'s 1024-byte route bound, rather than dropping it.** `ip` prints `addraw_l`'s error and sends the route without its encap, because `iproute_modify` ignores the return. Sending a route the user didn't ask for isn't parity worth having. No form reaches the bound.
+- **The tunnel flags are big-endian.** `TUNNEL_KEY`, `TUNNEL_CSUM` and `TUNNEL_SEQ` are `__cpu_to_be16`, and `rta_addattr16` writes them as they are, so `key csum seq` sends bytes `00 0d`.
+- **Refusals exit 1, as goip's other route and nexthop arms do.** `ip` exits 255 for them; goip's `invargErr` wraps `ErrInvalidArgument`, and only `ErrLinkUsage` maps to 255. So an encap refusal is an O5 row, not a goip-parity pick.
+- **geneve's class and type are base 0, like `ip`'s `get_be16` and `get_u8`.** `0102` is octal 66 and `80` is decimal, so the plan's forms write `0x0102:0x80`, and a corner form keeps the base-0 reading.
+- **`any` and `all` send an empty address.** `get_addr` gives them a bytelen of 0, and `rta_addattr_l` sends that as an attribute with no payload. `PutIPEncap` accepts an empty `Addr` for DST and SRC.
+- **No `getBe*` helpers.** goip reads with its `getU16`/`getU32`/`getU64`, and xtcpnl writes big-endian, so the byte swap lives in one place.
+- **A route's bound is `addraw_l`'s, which counts the request so far.** `addraw_l(&req.n, 1024, …)` checks the aligned message length plus the encap against 1024, so the header, the rtmsg and every attribute before `encap` count, which is tighter than the 1020 bytes `buf[1024]` holds. goip refuses with `addraw_l`'s message; `ip` prints it and sends the route without the encap.
+- **A hop's bound is what is left of `parse_nexthops`' 4096 bytes.** The `RTA_MULTIPATH` header, the earlier hops, this hop's `rtnexthop` and its attributes so far count. Over it, `parse_one_nh` fails and `ip` exits 255 with "Error: cannot parse nexthop"; goip refuses with the same text, and exits 1 as its other refusals do.
+- **LE2's capture rows wait for LE3.** The plan's "each `lwtroute4`, `lwtroute6`, `lwthop` form" (LE2-T01) and "each `lwtnh` form" (LE2-T02), byte for byte, need the captures LE3-T02 makes, so LE3-T03's O5 rows check those forms, and `TestRouteWriteEncap`'s and `TestNexthopWriteEncapIP`'s expected bytes are hand-built.
+- **A nexthop object's bound is a route's.** `ipnh_modify`'s encap is the same `buf[1024]` and `addraw_l(&req.n, 1024, …)`, so the header, the nhmsg and the attributes before `encap` count. `EncodeLwtEncapAs` gives the encoder the two `NHA_*` types, so the three places share one encoder.
+- **The plan's counts were off by the base-0 form.** Adding "`ip` `geneve_opts`, base 0" made 27 forms but moved the count to rc 2 rather than rc 0; the forms are 21 at rc 0, 2 at rc 2 (implicit null, geneve data of 3 bytes) and 4 at rc 255. `deriveDupGone` takes three duplicates from each of the four spaces, 12, not "up to 9".
+- **A tunnel's id is `tun_id` in the axes.** `LWTUNNEL_IP_ID` and a nexthop object's own id are both `id` on the command line. With both under `id`, `nhHasID` took the tunnel's 1 for the nexthop's and skipped `ip6`'s duplicate, which has no tunnel id. O3 reads `tun_id` and `hopN_tun_id`.
+- **O5's zeroing has to reach inside the options.** The second boot's bytes differ from the first's in the padding after geneve's `CLASS` (2 bytes) and `TYPE` (3 bytes), two nests below `NHA_ENCAP`, as well as after a route's and a hop's `RTA_ENCAP_TYPE`. So `wsO5ZeroSubPad`, which walked one level, now recurses into every `NLA_F_NESTED` attribute inside the encap (LE3-T03).
+- **O5 calls an rc 255 encap refusal `same`.** `ip` exits 255 and goip 1 (`invargErr`), and neither sends a request, which is what O5 compares. So the four rc 255 forms can be O5 rows but not goip-parity picks, which need goip to exit 0.
+- **nlparity learned `RTA_MULTIPATH`'s hops before the VM run, not after.** The plan said to check `samePastPadding` on a hop row first. But `RTA_MULTIPATH` isn't `NLA_F_NESTED`, so the hop's bytes are compared whole, and the captures already show the two bytes after a hop's `RTA_ENCAP_TYPE` vary (`40 86` in fibt's, and between `lwthop/ec-002`'s two boots). A hop row would pass or fail by the stack's luck. `sameHopsPastPadding` compares each `rtnexthop` header exactly and its attributes past their padding, in route messages only.
+- **The full run had the rows gated, as LF3-T02's did.** The plan puts the full run before gating. With the 23 rows in `gated_commands`, a finding on one fails the run rather than being reported as ungated, so a clean run with them gated also covers the plan's order.

+# goip ↔ `ip` parity: lightweight-tunnel encap on routes and nexthops
+
+## Status
+
+**Last updated:** 2026-11-04
+
+**Summary:**
+- **Closed, 2026-11-04.** goip builds `encap` `mpls`, `ip` and `ip6`, with the tunnel options, on a route, in a hop and on a nexthop object. The `lwt` workbench family's 39 rows are O3- and O5-checked, and 23 goip-parity rows are gated ([status](goip-lwt-encap-status.md), V025–V029). The rest of this section is the state the plan started from.
+- [goip-live-forms.md](goip-live-forms.md) is finished. What still sends nothing from goip where `ip` sends a write is `encap`, apart from `netns` and `xdp` programs, which goip refuses by design:
+  - **a route's `encap`** (`ip route add … encap TYPE …`) is `routeArmUnsupported` (`internal/goip/route_write.go:166`);
+  - **a hop's `encap`** (`nexthop encap TYPE …`) is refused in `parseOneNh` (`route_write.go:660`). These are O5's two `refuses` rows, `fibt/fib_notify_test-001` and `fibt/fib6_notify_test-001` (`internal/goip/testdata/ws-differential.txt`);
+  - **a nexthop object's `encap`** builds `mpls` alone (`internal/goip/nexthop_write.go:197`, `pkg/xtcpnl/xtcpnl_lwt_mpls.go`).
+- This plan builds `lwt_parse_encap`'s `mpls`, `ip` and `ip6` types, with the `ip` and `ip6` tunnel options (`geneve_opts`, `vxlan_opts`, `erspan_opts`), in all three places. Then it adds rows, captures, O3, O5, goip-parity rows and a VM gate, as goip-live-forms.md did.
+- The other encap types (`seg6`, `seg6local`, `ioam6`, `rpl`, `ila`, `bpf`, `xfrm`) stay refused for now. They are the [follow-on](#out-of-scope).
+
+**Progress** is tracked in [goip-lwt-encap-status.md](goip-lwt-encap-status.md).

+- **`ip` is 7.2.0** and the guest kernel 7.3.0, as in [goip-write-keywords.md](goip-write-keywords.md#reference-sources). Line numbers below are `v7.2.0`'s:
+  - `ip/iproute_lwtunnel.c`:
+    - `read_encap_type` is at 76 and `lwt_parse_encap` at 2278;
+    - the encap parsers are `parse_encap_mpls` 1590, `parse_encap_ip` 1817 and `parse_encap_ip6` 2029;
+    - the option parsers are `lwtunnel_parse_geneve_opt` 1639, `lwtunnel_parse_geneve_opts` 1708, `lwtunnel_parse_vxlan_opts` 1725 and `lwtunnel_parse_erspan_opts` 1741.
+  - `ip/iproute.c`: a route's `encap` is at 1517, a hop's at 1074 in `parse_one_nh` (1018), and `parse_nexthops` is at 1100. `ip/ipnexthop.c:1095` is a nexthop object's.
+- **The kernel's checks** are in `net/ipv4/ip_tunnel_core.c`: `ip_tun_build_state` 705, `ip6_tun_build_state` near 1007, and the geneve data length `% 4` at 532. The MPLS label check is `nla_get_labels` in `net/mpls/af_mpls.c` (implicit null at 1838).
+- **The generator, the workbench, the oracles and the selection** are as in [goip-live-forms.md](goip-live-forms.md#reference-sources).
+
+## What `ip` sends
+
+`lwt_parse_encap` reads the type, then a second `NEXT_ARG`. With `argc <= 1` left, it calls `missarg("encap type")`, so the type's first argument can't be the command's last word. It writes two attributes:
+- `ENCAP | NLA_F_NESTED` (`rta_nest` sets the flag), holding the type's sub-attributes;
+- then `ENCAP_TYPE` as a u16.
+
+**Where the two attributes go:**
+
+| place | attributes | buffer | written |
+|---|---|---|---|
+| a route | `RTA_ENCAP`, `RTA_ENCAP_TYPE` | `char buf[1024]`, copied by `addraw_l(&req.n, 1024, …)` | where the keyword is in argv. An `addraw_l` over 1024 bytes prints an error and returns -1, which `iproute_modify` ignores, so the route is sent without its encap |
+| a hop | `RTA_ENCAP`, `RTA_ENCAP_TYPE` inside the `rtnexthop` | `parse_nexthops`' `char buf[4096]` | in the hop's argv order; `rtnh_len` grows by both |
+| a nexthop | `NHA_ENCAP`, `NHA_ENCAP_TYPE` | `char buf[1024]`, copied by `addraw_l` | where the keyword is in argv, as today for `mpls` |
+
+None of the three buffers is zeroed. `rta_addattr_l` leaves alignment padding as it finds it (goip-live-forms-status.md's decision log, "O5 zeroes `ip`'s encap padding"), so `ip` sends stack bytes in the padding in all three places.
+
+**The types:**
+
+| type | `ENCAP_TYPE` | sub-attributes, in the order written |
+|---|---|---|
+| `mpls LABELS [ttl N]` | 1 | `MPLS_IPTUNNEL_DST` (the `mpls_pton` stack), `MPLS_IPTUNNEL_TTL` u8 for each `ttl` read (a second is `duparg2`) |
+| `ip …` | 2 | in argv order: `id` → `LWTUNNEL_IP_ID` be64 (`get_be64`); `dst`/`src` → `LWTUNNEL_IP_DST`/`SRC` (`get_addr` in AF_INET, which exits 1 on a bad address); `tos` → `LWTUNNEL_IP_TOS` u8 (`rtnl_dsfield_a2n`); `ttl` → `LWTUNNEL_IP_TTL` u8; one of `geneve_opts`/`vxlan_opts`/`erspan_opts` → `LWTUNNEL_IP_OPTS \| NLA_F_NESTED`. Then, last and only if non-zero, `LWTUNNEL_IP_FLAGS` from `key`, `csum`, `seq`. `TUNNEL_KEY`, `TUNNEL_CSUM` and `TUNNEL_SEQ` are `__cpu_to_be16(0x4)`, `(0x1)` and `(0x8)` (`include/uapi/linux/if_tunnel.h:171-174`), so `rta_addattr16` sends them big-endian |
+| `ip6 …` | 4 | as `ip` in AF_INET6, with `tc` → `LWTUNNEL_IP6_TC` and `hoplimit` → `LWTUNNEL_IP6_HOPLIMIT` in place of `tos` and `ttl` |
+
+Each keyword's second use is `duparg2` (exit 255). The three option words share one counter, so a second option of any kind is `duparg2("opts", …)`. An unknown word ends the type, and the caller reads it.
+
+**The options**, inside `LWTUNNEL_IP_OPTS`:
+- **`geneve_opts C:T:D[,C:T:D…]`:** one `LWTUNNEL_IP_OPTS_GENEVE | NLA_F_NESTED` per comma-separated option, holding `CLASS` be16 (`get_be16`, base 0, so `0102` is octal), `TYPE` u8 (`get_u8`, base 0) and `DATA` (`hex2mem` of `strlen/2` bytes). An empty field is skipped, and a fourth field is "Unknown "geneve_opts" type" (exit 255 through `invarg`).
+- **`vxlan_opts GBP`:** `LWTUNNEL_IP_OPTS_VXLAN | NLA_F_NESTED` holding `GBP` u32.
+- **`erspan_opts V:I:D:H`:** `LWTUNNEL_IP_OPTS_ERSPAN | NLA_F_NESTED` holding `VER` u8, `INDEX` be32, `DIR` u8 and `HWID` u8. An empty field is skipped.
+
+## The forms
+
+One new family, `lwt`, in a new `tools/nlcapgen/matrix_lwt.go`, built as `kwlive` is:
+- each space has two axes, the verb (`add` alone) and the form;
+- `Derive` adds up to three duplicate adds (rc 2, `EEXIST`) per space;
+- the setup is GW5's `d0` (the dummy, `addrgenmode none`, up, `192.0.2.10/24`, `2001:db8:1::10/64 nodad`), and every step is `ip`;
+- every space loads `kwNhModules`, so the `mpls` rows don't autoload `mpls_router` mid-batch.
+
+"rc" is the generator's expectation. LF2-T01's rule holds: the first capture confirms or corrects it, and any correction goes in the decision log.
+
+| space | form | cmd (after `ip`) | rc | sends |
+|---|---|---|---|---|
+| `lwtroute4` | `mpls`, one label | `-4 route add 198.51.100.0/24 encap mpls 100 via 192.0.2.1 dev d0` | 0 | `RTA_ENCAP`{`DST` 100, bottom bit}, `RTA_ENCAP_TYPE` 1 |

+
+That makes 27 forms (21 rc 0, 2 rc 2, 4 rc 255), plus 12 duplicates: `deriveDupGone`'s three per space, over four spaces.
+
+## Out of scope
+
+- **`seg6`, `seg6local`, `ioam6`, `rpl`, `ila`, `bpf`, `xfrm`.** Each has its own grammar and sub-structures (`struct ipv6_sr_hdr`, the seg6local actions, the ioam6 trace, BPF object loading). They stay `ErrNotImplemented` and get a follow-on plan, in order of how often the kernel selftests use them: `ioam6`, `seg6`, `seg6local`, `rpl`, `ila`. `bpf` needs a program object, as `xdp` does, so it stays refused by design.
+- **`ttl-propagate` and `as`.** They aren't encap types. They stay `routeArmUnsupported`.
+- **The 1024-byte `addraw_l` bound.** goip refuses an encap the route buffer can't hold, with the same message. It doesn't send the route without the encap, as `ip` does. No form reaches the bound (the largest is about 100 bytes), and the decision log records the difference.
+- **Moving the existing families**, as in [goip-live-forms.md](goip-live-forms.md#out-of-scope).
+
+## Gates every task inherits
+
+[goip-live-forms.md's gates](goip-live-forms.md#gates-every-task-inherits), with these for the encoder:
+- **No nolint, no `#nosec`.** Lengths are checked through `pkg/cint`, as in the rest of xtcpnl.
+- **One encoder for all three places.** A route, a hop and a nexthop object call the same `lwtEncapArgs`, and differ only in the two attribute types and the builder they write to.
+
+## Phases and tasks

+
+### LE1 — the encoder
+
+#### LE1-T01 the `ip` and `ip6` encodings
+
+A new `pkg/xtcpnl/xtcpnl_lwt_ip.go` beside `xtcpnl_lwt_mpls.go`:
+- **`IPEncap`** holds the parsed sub-attributes in argv order, the options as a list, and the flags;
+- **`PutIPEncap(ab, encapAttr, typeAttr, family, e)`** writes the nest, the `LWTUNNEL_IP_*` or `LWTUNNEL_IP6_*` types for the family, and the type u16;
+- **`LwtEncap`** is the one value goip builds: `mpls` or `ip`/`ip6`;
+- **`EncodeLwtEncap`** gives the two attributes as `RouteAttr`s for a route or a hop.
+
+`TestPutIPEncap` (`xtcpnl_lwt_ip_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: `id` and `dst` | AF_INET, `id` 1, `dst` 203.0.113.5 | `ENCAP\|NESTED`{`ID` be64 1, `DST`}, `ENCAP_TYPE` 2, bytes as a hand-built golden |
+| positive: every scalar, then the flags | the "every scalar" form | sub-attributes in argv order, `FLAGS` be16 0xd last (bytes `00 0d`) |
+| positive: IPv6's types | AF_INET6, `tc` and `hoplimit` | `LWTUNNEL_IP6_TC` 5 and `HOPLIMIT` 6, `ENCAP_TYPE` 4 |
+| positive: two geneve options | two `C:T:D` | two `GENEVE\|NESTED` nests inside `OPTS\|NESTED` |
+| positive: vxlan and erspan | one each, separately | `VXLAN`{`GBP` u32}; `ERSPAN`{`VER`, `INDEX` be32} |
+| negative: no flags | none of `key`/`csum`/`seq` | no `FLAGS` attribute |
+| boundary: geneve data of 0 bytes | `0102:80:` | `CLASS` and `TYPE`, no `DATA` |
+| boundary: the builder one byte short | a buffer one byte under the encoding | `ErrAttrNoSpace`, nothing half-written past the length |
+| corner: an empty geneve field | `:80:00112233` | no `CLASS` |
+| corner: `EncodeLwtEncap` for a route | the `mpls` form | the same bytes as `PutMplsEncap` into `RTA_ENCAP` |
+
+**Mutation check:** the flags written before the options; the flags little-endian; `INDEX` little-endian; the `NLA_F_NESTED` bit dropped from a geneve option.
+
+#### LE1-T02 `lwtEncapArgs`
+
+In `internal/goip`, a new `lwt_encap_args.go`:
+- `lwtEncapArgs(args, i)` is `lwt_parse_encap` and the three type parsers. It returns an `xtcpnl.LwtEncap` and the index of the last word it used, with `ip`'s error text for each refusal.
+- `mplsEncapArgs` moves here unchanged.
+- The helpers it needs are `hex2mem` and the existing `getU16`/`getU32`/`getU64` and `rtnlDsfieldA2N` (`rule_write.go:513`). `get_be*` are `get_u*` and then a byte swap; xtcpnl does the swap, so goip keeps the host value.
+
+`TestLwtEncapArgs` (`lwt_encap_args_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: each form's argv | the forms table's encap words | the `LwtEncap` the table's "sends" column says, and the index of the last encap word |
+| positive: an unknown word ends the type | `ip dst 203.0.113.5 via 192.0.2.1` | stops before `via` |
+| negative: an unknown type | `foo 1` | `"encap type" value is invalid`, `ErrInvalidArgument` |
+| negative: a duplicate | `ip ttl 1 ttl 2` | `duparg2("ttl", "2")` |
+| negative: two option kinds | `ip geneve_opts … vxlan_opts 1` | `duparg2("opts", …)` |
+| negative: a bad address | `ip dst 300.1.1.1` | `get_addr`'s message, exit 1 as `ErrInvalidArgument` |
+| negative: a fourth geneve field | `0102:80:00:01` | `"geneve_opts" value is invalid` |
+| boundary: the type's word last | `ip key` at the end | `missarg("encap type")` |
+| boundary: `tos` is base 16 | `tos 0x10`, `tos 10`, `tos AF11` | 0x10, 0x10 and 0x28, through `rtnlDsfieldA2N` (`rule_write.go:513`) |
+| corner: odd-length geneve data | `0102:80:001` | one byte, `0x00`, as `hex2mem` of `strlen/2` |
+| corner: `help` as the type | `help` | `ErrNotImplemented`, as now |
+| corner: a type this plan leaves out | `seg6 …` | `ErrNotImplemented`, naming the type |
+
+**Mutation check:** `strlen/2` rounded up; a second `opts` accepted; geneve's class read base 16.
+
+### LE2 — goip's three places
+
+#### LE2-T01 a route and a hop
+
+- `routeArmEncap` replaces `routeArmUnsupported` for `encap`. It calls `lwtEncapArgs` and appends the two `RouteAttr`s to `Attrs` where the keyword is.
+- `parseOneNh`'s `encap` appends them to the hop's `Attrs`. `as` stays refused.
+- The 1024-byte route bound is checked as in [out of scope](#out-of-scope).
+
+`TestRouteWriteEncap` (`route_write_encap_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: each `lwtroute4`, `lwtroute6`, `lwthop` form | the argv | a request byte for byte as the capture's, padding zeroed |
+| positive: `encap` before `via` | `encap mpls 100 via 192.0.2.1` | `RTA_ENCAP`, `RTA_ENCAP_TYPE`, then `RTA_GATEWAY` |
+| positive: the two fibt rows | `fib_notify_test-001`, `fib6_notify_test-001` | built, no longer refused |
+| negative: `as` in a hop | `nexthop as 10.0.0.1 …` | `ErrNotImplemented`, as now |
+| boundary: an encap over the bound | a stack of 64 labels plus geneve options | refused, with `addraw_l`'s message |
+| corner: an encap and `metric` | `… encap ip … metric 10` | `RTA_PRIORITY` after the encap, as in argv |
+
+**Mutation check:** the encap appended after `RTA_OIF`; a hop's encap put on the route.
+
+#### LE2-T02 a nexthop object
+
+`nexthopWrite.encap` calls `lwtEncapArgs`. `ip` and `ip6` are no longer `ErrNotImplemented`, and `mpls` is unchanged.
+
+| description | input | expected |
+|---|---|---|
+| positive: each `lwtnh` form | the argv | `NHA_ENCAP`, `NHA_ENCAP_TYPE` as the capture's |
+| positive: `mpls` unchanged | the four `kwnh` forms | the same bytes as before the change |
+| negative: a type this plan leaves out | `encap seg6 …` | `ErrNotImplemented` |
+
+**Done when:** both tables pass; O5's golden, regenerated, shows the two fibt rows moved from `refuses` (to `same`, or to a recorded `differs`, which LE3-T03 closes); lint-baseline and netlink-audit pass.
+
+### LE3 — the rows, the captures and the oracles
+
+#### LE3-T01 the `lwt` family
+
+As [LF1-T01](goip-live-forms.md#lf1-t01-the-kwlive-family), for the forms table. `TestLwtSpaces` checks each row's cmd and rc, the 27 forms and 12 duplicates, every setup step `ip`, the modules, and the same bytes twice.
+
+#### LE3-T02 capture
+
+As [LF2-T01](goip-live-forms.md#lf2-t01-capture): two fresh-boot batches that agree, and `TestWsCorpusRows` over them.
+
+#### LE3-T03 O3 and O5
+
+- **O3:** `pkg/xtcpnl/xtcpnl_ws_lwt_test.go` decodes each row's request and checks the encap against the row's `axes`: the type, each sub-attribute's width and value, the option nests and the flags.
+- **O5:** the four spaces go in `wsO5Spaces`. `wsO5ZeroEncapPad` widens from a nexthop's `NHA_ENCAP` to a route's `RTA_ENCAP` and to each hop's inside `RTA_MULTIPATH`, so `ip`'s stack bytes don't make a row `differs`.
+
+| description | input | expected |
+|---|---|---|
+| positive: every form's encap | `TestWsLwtCorpus` | each row's request as its axes |
+| positive: every new row `same` | `TestWsGoipDifferential` | no new row in `ws-differential.txt`; the fibt rows `same` |
+| positive: a hop's padding zeroed | a hand-built `RTA_MULTIPATH` with `7f` after `RTA_ENCAP_TYPE` | zeroed; the hop's other bytes kept |
+| negative: an O3 row with `INDEX` little-endian | hand-built | the check fails |
+| negative: no existing row moves | the golden's diff | only the summary counts and the two fibt rows |
+| corner: a refusal at rc 255 | the four rc 255 rows | zero requests (O2), and goip refuses too |
+
+**Mutation check:** the hop padding left; a route's `RTA_ENCAP` not zeroed; O3's flags check dropped.
+
+**Done when:** both tables pass; lint-baseline and netlink-audit pass.
+
+### LE4 — the matrix rows and the VM gate
+
+#### LE4-T01 the rows
+
+As [LF3-T01](goip-live-forms.md#lf3-t01-the-rows): a form table for the `lwt` spaces in `commands_gw_test.go`, and `gw_lwt*` rows in `commands.go`, one per form and rc. nlparity already compares a nest past its padding (goip-live-forms-status.md V017). A hop's encap sits inside `RTA_MULTIPATH`, which isn't a nest, so the task checks `samePastPadding` there first. If a hop row diverges on padding alone, nlparity learns `RTA_MULTIPATH`'s hops in this task, with a table of its own.
+
+#### LE4-T02 the VM gate
+
+As [LF3-T02](goip-live-forms.md#lf3-t02-the-vm-gate): a `--section route,nexthop` run, twice clean, then the full run; then the rows are gated.
+
+**Done when:** both runs are clean, the rows are gated, and lint-baseline passes. It closes the plan.

+**Last updated:** 2026-11-04
+
+**Summary:**
+- The design and the task plan are in [goip-lwt-srv6.md](goip-lwt-srv6.md). This document tracks progress against them.
+- The plan is written (DOC001). It follows [goip-lwt-encap.md](goip-lwt-encap.md), which is closed ([its status](goip-lwt-encap-status.md)). goip will build `seg6`, `seg6local`, `ila`, `xfrm`, `ioam6` and `rpl` for a route, a hop and a nexthop object. A 56-form `lwtx` workbench family checks it, followed by goip-parity rows and a VM gate. The guest kernel lacks `ioam6` and `rpl`, so their rows check the request alone.
+- LX1-T01 is done: `pkg/xtcpnl/xtcpnl_lwt_seg6.go` builds `parse_srh`'s SRH (`SRH`), `encap seg6` (`Seg6Encap`) and `encap seg6local` (`Seg6LocalEncap`), which `LwtEncap` and `PutLwtEncap` now take. `TestSRH`'s and `TestPutSeg6Encap`'s goldens are hand-built from the uapi headers (V001–V003).
+- LX1-T02 is done, and LX1 is closed: `pkg/xtcpnl/xtcpnl_lwt_other.go` builds `encap ila` (`IlaEncap`), `xfrm` (`XfrmEncap`), `ioam6` (`Ioam6Encap`, with `ioam6_trace_hdr`) and `rpl` (`RplEncap`, through `RplSRH`). `LwtEncap` takes all eight types. `TestPutLwtEncapOther`'s goldens are hand-built (V004–V006).
+- LX2-T01 is done: `lwtEncapArgs` reads all six types (`internal/goip/lwt_encap_srv6_args.go`), with `ip`'s argv quirks, so a route, a hop and a nexthop object build them. It takes the resolver, so `seg6local`'s `iif`/`oif` and `xfrm`'s `link_dev` are looked up as `ip` does, inside the loop. Only `bpf` is still `ErrNotImplemented`, and the refusal rows that named `seg6` now name it (V007–V009).
+- LX2-T02 is done, and LX2 is closed. No new code was needed: `TestRouteWriteSrv6` and `TestNexthopWriteSrv6` check that each type lands where its keyword is, on a route, in a hop and on a nexthop object. They also check that `seg6local`'s `oif` is looked up before `dev`, the route bound at 59 segments, and the quirks that change what the caller reads next. O5's golden is unchanged (V010–V012).
+- LX3-T01 is done: `nlcapgen matrix -family lwtx` writes 73 rows to `nix/microvms/workbench/lwtx.rows.jsonl`: the 56 forms (32 at rc 0, 11 at rc 2, 1 at rc 1, 12 at rc 255) in eight spaces, and 17 duplicate adds. Every row loads `ila` and `xfrm_interface`. The plan's space and duplicate counts were corrected to these (V013–V015).
+- LX3-T02 is done: two fresh-boot batches agree on all 73 rows, and every rc is as the generator wrote it. The first batch is the corpus, in `pkg/xtcpnl/testdata/7_3_0/ws/` (228 KB). `TestWsCorpusRows` corrected two rows' `refused_by`: `seg6local`'s `oif nosuch` and `xfrm`'s `link_dev` both look the device up first, so one is refused by the kernel (ENODEV) and the other is ack-then-fail. The boots' only byte differences are `ip`'s padding after a route's `RTA_ENCAP_TYPE` (V016–V018).
+- LX3-T03 is done, and LX3 is closed. O3 (`pkg/xtcpnl/xtcpnl_ws_lwtx_test.go`) checks the 60 captured requests' encaps against their axes, and each SRH's segments against the row's own `segs`, last to first. The 13 rows `ip` refuses before sending send none. O5 has the eight spaces: all 73 rows are `same`, no existing row moved, and the encap-padding zeroing now reaches 41 rows (V019–V021).
+- LX4-T01 is done: 43 goip-parity write rows (`gw_seg6route6_*`, `gw_seg6route4_*`, `gw_seg6local_*`, `gw_ila_*`, `gw_xfrm_*`, `gw_lwtxreq_*`, `gw_lwtxhop_*`, `gw_lwtxnh_*`), one per rc 0 and rc 2 form, picked by `TestGwLwtxMatrixRows` from the `lwtx` rows. The rows stay ungated until LX4-T02 (V022–V024).
+- LX4-T02 is done, and LX4 and the plan are closed. On dfe50cf3, two `--section route,nexthop` runs passed 167 of 167, all 43 lwtx rows among them (V025). The full run with the rows gated passed 1373 of 1373 (V026). The 43 rows are in `gated_commands` and `TestAllowlistCommitted`'s earned list, and the GW matrix tables' gated check and `TestUngatedSurfaceIsNotVacuous` no longer skip them: `gwIsLwtx` is gone (V027–V028).
+- After the plan closed, the `ip` bugs it found were written up in `docs/netlink/upstream/iproute2-lwtunnel-encap-parsing.md` (not committed) and reproduced on the host. That added one goip row (`lblen N` last) and corrected the `hdrlen` decision (V029). Building and testing the write-up's patches found a ninth bug, a route sent without its encap past the request bound, which goip already refuses. It also corrected the plan's note on the `segs` cut, which is reachable inside the bound (V030). PR #287's review found a Unicode fold in `llProtoA2N`, `cStrtoul` reading an unknown base as decimal, and raw ifindex conversions, all fixed in goip (V031), and three gaps in the soft restart's secrets handoff, fixed in `cmd/xtcp2` (V032).
+
+**Next action:** none; the plan is closed. `bpf` and `End.BPF` stay refused by design ([out of scope](goip-lwt-srv6.md#out-of-scope)).

+## Decision log
+
+- **`ioam6` and `rpl` are request-only.** nixpkgs' `linux_latest` 7.3 leaves `IPV6_IOAM6_LWTUNNEL` and `IPV6_RPL_LWTUNNEL` unset, so `lwtunnel_valid_encap_type` answers `EOPNOTSUPP`. A custom guest kernel would rebuild every VM flavor. The request is goip's half of parity, and `ip` sends it before the kernel answers, so the rows compare it at rc 2.
+- **The order follows the guest kernel.** goip-lwt-encap.md put `ioam6` first, by selftest use. `seg6` and `seg6local` come first here: the selftests use them most (12 `srv6_*` scripts), and the kernel builds them.
+- **goip copies `ip`'s argv quirks rather than fixing them.** These are `xfrm` swallowing the rest of the command, `ioam6`'s and `seg6local`'s `srh` end-of-argv step back, and `hmac` ignoring a bad number. Each changes what is sent, so parity means doing the same. Each has a goip test row and a workbench form.
+- **`ila`'s short locator sends zeros, not `ip`'s stack bytes.** `get_addr64` leaves the groups it doesn't read uninitialized. No form uses a short locator, since the bytes `ip` sends there can't be compared.
+- **`bpf` and `End.BPF` stay refused.** They load a program object, as `xdp` does.
+- **`SRH` takes the slot count, not a flag.** The plan had `SRH(segs, hmac, encap)`. `parse_srh` counts the commas in `segs`, but `strtok` skips an empty field, so `a,,b` has three slots and two addresses, and slot 0 stays zero. The caller counts the slots, with `inline`'s and `End.B6`'s extra one, and `SRH` writes the addresses it is given from the top.
+- **`LwtEncap` stays one struct of pointers.** `PutLwtEncap` counts the fields set and refuses anything but one. The new types go through `putLwtNest`, which writes the nest and the type as `lwt_parse_encap` does. `mpls` and `ip` keep their own writers, unchanged.
+- **`lwtEncapArgs` takes the resolver, and a route keeps it.** `seg6local`'s `iif` and `oif` and `xfrm`'s `link_dev` are `ll_name_to_index` inside `lwt_parse_encap`, so `ip`'s lookup goes out mid-loop, before `dev`'s. `routeParseState` holds the resolver, so the order is the same. It caches, as `ll_map` does.
+- **The exits are `ip`'s where `ip` calls `exit` or `missarg`.** `missarg`, `nodev`, "Missing action type" and `lwt_xfrm_usage` are exit 255, through `linkUsage`. `invarg`, `duparg2` and `get_addr` stay exit 1, as goip's other route and nexthop refusals do (goip-lwt-encap-status.md's decision log), and "Bad locator" is exit 1 in both.
+- **`next-csid` as the last word is refused as incomplete.** `seg6local_parse_flavors` steps past the list with `NEXT_ARG_FWD`, unchecked, and reads the word there, so `ip` reads past argv's end and crashes. After `nflen`'s value it steps forward and back without reading, so `nflen N` last is fine in both.
+- **`seg6local`'s `nh4 any` and `nh6 any` send an empty attribute.** `get_addr` gives them no bytes, and `rta_addattr_l` sends the empty payload. `putSeg6LocalItem` takes an empty address, as `putIPEncapItem` does for `dst any`.
+- **An SRH past `hdrlen`'s u8 is refused with the route bound's message.** `ip` wraps `hdrlen` and copies only the wrapped length, so it doesn't always hit the 1024-byte buffer: 128 `::` segments wrap `hdrlen` to 0, and `ip` sends an 8-byte SRH whose `first_segment` is 127, which the kernel refuses (`EINVAL`, rc 2). goip refuses the 128 slots before sending, as it would at any count past the bound, so it exits 1 where `ip` exits 2. This was found after the plan closed, checking the write-up in `docs/netlink/upstream/iproute2-lwtunnel-encap-parsing.md`, and corrects this entry's first version, which said every wrapping header was past the buffer.
+- **`ila` reuses `obj_ila.go`'s `ilaAddr64` and name tables, and `xtcpnl_ila.go`'s `ILAAttr*`.** LX1-T02 had defined the attribute numbers a second time; they were removed.
+- **`ioam6` and `rpl` share one space, `lwtxreq`, whose forms are all `Judge`d negatives.** The guest kernel refuses even the forms `ip` sends, so the space has no rc 0 row. A `Bad` value needs a positive row as its base (`negatives` takes `pos[0]`), so the forms are axis values, and `Judge` gives each its refusal. There are eight spaces, not nine, and 17 duplicates, since only spaces with rc 0 forms get them.
+- **A refusal after a device lookup is the lookup's, not `ip`'s.** `seg6local`'s `oif nosuch` sends `ll_name_to_index`'s get, which the kernel refuses (ENODEV), before `exit(nodev)`. `xfrm`'s `link_dev d0` is acknowledged before `lwt_xfrm_usage`. So the first is `refused_by: kernel` and the second `ack-then-fail`, as `TestWsCorpusRows` classifies them. The captures were kept, and only their `cmd.json` expectation corrected to the regenerated rows'.
+- **O3 checks an SRH's segments against the row's cmd, not its axes.** The axes carry the slot count. The addresses are the `segs` words, so `lwtxProblem` reads them from the cmd as `strtok` would and checks them last to first, with the slots below zero. That covers the order without a fact per segment.
+- **The rc 1 `ila` form stays O5's, as the rc 255 forms do.** The plan counted it among the goip-parity rows, since goip exits 1 as `ip` does. But a GW row is rc 0 or 2 (`gwRcs`, `runGwMatrix`'s "no row ip refused before sending"), and a row that sends nothing has no request for nlparity to compare. O5 already holds it `same`.

+# goip ↔ `ip` parity: `seg6`, `seg6local` and the other encap types
+
+## Status
+
+**Last updated:** 2026-11-04
+
+**Summary:**
+- **Closed, 2026-11-04.** goip builds `encap` `seg6`, `seg6local`, `ila`, `xfrm`, `ioam6` and `rpl` on a route, in a hop and on a nexthop object. The `lwtx` workbench family's 73 rows are O3- and O5-checked, and 43 goip-parity rows are gated ([status](goip-lwt-srv6-status.md), V025–V028). The rest of this section is the state the plan started from.
+- [goip-lwt-encap.md](goip-lwt-encap.md) is closed. goip builds `encap` `mpls`, `ip` and `ip6` on a route, in a hop and on a nexthop object. Every other type is `ErrNotImplemented` from `lwtEncapArgs` (`internal/goip/lwt_encap_args.go:78`), in all three places.
+- This plan builds `seg6`, `seg6local`, `ila`, `xfrm`, `ioam6` and `rpl`, which is every type `lwt_parse_encap` reads except `bpf`. Then it adds rows, captures, O3, O5, goip-parity rows and a VM gate, as goip-lwt-encap.md did.
+- **The order follows the guest kernel, not the selftests.** nixpkgs' `linux_latest` 7.3 has `IPV6_SEG6_LWTUNNEL=y`, `IPV6_SEG6_HMAC=y`, `IPV6_ILA=m` and `XFRM_INTERFACE=m`, but not `IPV6_IOAM6_LWTUNNEL` or `IPV6_RPL_LWTUNNEL`. So `seg6`, `seg6local`, `ila` and `xfrm` are checked end to end. For `ioam6` and `rpl`, the kernel answers `EOPNOTSUPP` ("lwt encapsulation type not supported", `lwtunnel_valid_encap_type`), so their rows check the request alone, at rc 2.
+
+**Progress** is tracked in [goip-lwt-srv6-status.md](goip-lwt-srv6-status.md).

+## Reference sources
+
+- **`ip` is 7.2.0** and the guest kernel 7.3.0, as in [goip-lwt-encap.md](goip-lwt-encap.md#reference-sources). In `ip/iproute_lwtunnel.c` (`v7.2.0`):
+  - `parse_srh` is at 900, `parse_encap_seg6` 955, `parse_rpl_srh` 1050 and `parse_encap_rpl` 1083;
+  - `parse_ioam6_freq` is at 1125 and `parse_encap_ioam6` 1150;
+  - `seg6local_fill_counters` is at 1370, `seg6local_parse_flavors` 1393 and `parse_encap_seg6local` 1447;
+  - `parse_encap_ila` is at 1951 and `parse_encap_xfrm` 2229;
+  - the name tables are `seg6_mode_types` (133), `ioam6_mode_types` (315), `seg6_action_names` (391) and `seg6_flavor_names` (161). `ip/ila_common.h` has ila's.
+  - `lib/utils.c:518`'s `get_addr64` reads ila's locator.
+- **The kernel's checks:**
+  - `seg6_build_state` (`net/ipv6/seg6_iptunnel.c:753`) and `seg6_validate_srh` (`net/ipv6/seg6.c:26`);
+  - `seg6_local_build_state` and `seg6_action_table` (`net/ipv6/seg6_local.c:1584`), which give each action's required and optional attributes;
+  - `ila_build_state` (`net/ipv6/ila/ila_lwt.c:135`);
+  - `xfrmi_build_state` (`net/xfrm/xfrm_interface_core.c:73`);
+  - `lwtunnel_valid_encap_type` (`net/core/lwtunnel.c:152`), which autoloads `rtnl-lwt-<TYPE>` and gives `EOPNOTSUPP` without it.
+- **The selftests** using these types are `tools/testing/selftests/net/srv6_*.sh` (12 scripts), `ioam6.sh` and `vrf-xfrm-tests.sh`.
+- **The generator, the workbench, the oracles and the selection** are as in [goip-live-forms.md](goip-live-forms.md#reference-sources).
+
+## What `ip` sends
+
+Every type goes through `lwt_parse_encap`, so a route, a hop and a nexthop object get the same two attributes as for `ip` (goip-lwt-encap.md, [What `ip` sends](goip-lwt-encap.md#what-ip-sends)), with these inside:
+
+| type | `ENCAP_TYPE` | sub-attributes, in the order written |
+|---|---|---|
+| `seg6 mode M [tunsrc A] segs S[,S…] [hmac K]` | 5 | `SEG6_IPTUNNEL_SRH` (1): `struct seg6_iptunnel_encap` (an `int mode`, then the SRH); then `SEG6_IPTUNNEL_SRC` (2), 16 bytes, if `tunsrc` |
+| `seg6local action A [args…]` | 7 | in argv order: `ACTION` (1) u32, `TABLE` (3) u32, `VRFTABLE` (9) u32, `NH4` (4), `NH6` (5), `IIF` (6) u32, `OIF` (7) u32, `COUNTERS` (10) nest, `FLAVORS` (11) nest; `SRH` (2) last, if `srh` |
+| `ila LOC [csum-mode C] [ident-type T] [hook-type H]` | 3 | `ILA_ATTR_LOCATOR` (1) u64, then each keyword's u8 in argv order: `CSUM_MODE` (7), `IDENT_TYPE` (8), `HOOK_TYPE` (9) |
+| `xfrm if_id N [link_dev D]` | 10 | `LWT_XFRM_IF_ID` (1) u32, `LWT_XFRM_LINK` (2) u32, in argv order |
+| `ioam6 [freq K/N] [mode M] [tunsrc A] [tundst A] trace prealloc type T ns N size S` | 9 | `FREQ_K` (4) u32, `FREQ_N` (5) u32, `MODE` (1) u8, `SRC` (6) and `DST` (2) unless inline, then `TRACE` (3): `struct ioam6_trace_hdr`, 8 bytes |
+| `rpl segs S[,S…]` | 8 | `RPL_IPTUNNEL_SRH` (1): `struct ipv6_rpl_sr_hdr` and the segments |
+
+**The SRH (`parse_srh`):**
+- `nsegs` is the number of commas plus one. `inline` mode adds one more, left all zeros, for the packet's own destination. The call is `parse_srh(segbuf, hmac, encap)`, and `encap` is the mode, so `inline` (0) is the only mode treated as not encapsulating.
+- The length is `8 + 16 × nsegs`, plus 40 with `hmac`. `hdrlen` is `len/8 − 1`, `type` 4, and `segments_left` and `first_segment` are both `nsegs − 1`.
+- The segments are written last to first: the first address in argv goes in `segments[nsegs − 1]`.
+- `hmac K` sets `SR6_FLAG1_HMAC` (0x08) and appends the HMAC TLV: type 5, length 38, and `hmackeyid` be32. The 32 HMAC bytes are zero.
+- The struct is `malloc`ed and `memset`, so the payload has no stack bytes in it. `seg6_iptunnel_encap` is 4 bytes and the SRH a multiple of 8, so `SEG6_IPTUNNEL_SRH` needs no padding.
+
+**`seg6local`'s nests:**
+- `count` writes `COUNTERS`{`PACKETS` (2), `BYTES` (3), `ERRORS` (4)}, each u64 0.
+- `flavors F[,F…]` writes `FLAVORS`{`OPERATION` (1) u32, a bit for each of `psp` (1), `usp` (2), `usd` (3) and `next-csid` (4)}. With `next-csid`, it then writes `LCBLOCK_BITS` (2) u8 for `lblen` and `LCNODE_FN_BITS` (3) u8 for `nflen`, in that order, each if present.
+- The SRH is `parse_srh`'s, with `encap` true only for `End.B6.Encaps`. So `End.B6` gets the extra zero segment, as `seg6` `inline` does.
+
+**`ioam6`'s trace header:** `namespace_id` be16 (`ns`), a byte of zero (`nodelen` and `overflow`), `remlen` = `size / 4`, then `type_be32` = `htonl(type << 8)`. It is `calloc`ed.
+
+**`rpl`'s header:** `nexthdr` 0, `hdrlen` = `(8 + 16 × nsegs)/8 − 1`, `type` 3, `segments_left` = `nsegs`, and the four bytes of `cmpri`, `cmpre` and `pad` all zero. The segments are written last to first, as `seg6`'s.
+
+**The u8 attributes leave padding.** `ila`'s three u8s, `ioam6`'s `MODE` and `seg6local`'s `lblen` and `nflen` each leave three bytes of padding, which `rta_addattr_l` doesn't zero. LE3-T03's O5 zeroing and nlparity's nest compare already reach every nest in an encap, so this plan reuses them.
+
+## `ip`'s quirks goip copies
+
+These are what `ip` 7.2.0 does. goip copies each one, and the forms table has a row for each:
+
+- **`xfrm` swallows the rest of the command.** `parse_encap_xfrm`'s loop has no `else break`, so a word it doesn't know is skipped and the loop goes on to the end of argv. `encap xfrm if_id 1 dev d0` sends no `RTA_OIF`. A route that needs `dev` puts it before `encap`.
+- **`ioam6`'s keywords are positional:** `freq`, then `mode`, then `tunsrc`, then `tundst`, then `trace prealloc`, then `type`, `ns` and `size` in any order. A word out of that order is `missarg` of the next one expected. Each `NEXT_ARG` before `trace` needs a word after it, so `ioam6` can't end the command.
+- **`ioam6`'s trace loop ends one word early at the end of argv.** `while (NEXT_ARG_OK())` stops with `argv` on the last value it read, and the caller then reads that word again as a route keyword. So `… size 12` as the command's last words gives the route `12` as a second destination, which `ip` refuses. A row puts `dev d0` after the trace.
+- **`seg6local`'s `srh segs S` at the end of argv** breaks out before stepping past `S`, so the caller reads `S` again as a route keyword, as `ioam6`'s trace loop does.
+- **`seg6`'s and `seg6local`'s `hmac` ignore a bad number.** `get_u32`'s return isn't checked, so `hmac x` is `hmac 0`: no HMAC TLV and no flag.
+- **`seg6` with no `mode`** sends `mode` −1 (`0xffffffff`) and, with no `segs`, one zero segment. Only `hmac` can come before `mode`, since `segs` and `tunsrc` before `mode` are `invarg`. The kernel refuses mode −1 with `EINVAL` ("invalid SRv6 encapsulation mode").
+- **`seg6`'s `segs` is cut at 1023 bytes** (`strlcpy` into `segbuf[1024]`).
+- **`ila`'s locator with fewer than four groups** leaves the rest of `get_addr64`'s `val.v16` uninitialized, so `ip` sends stack bytes there. goip sends zeros, and the decision log records it. The forms always give four groups.
+- **An `iif`, `oif` or `link_dev` that doesn't exist** is `exit(nodev(...))`, which is exit 255. A bad `ila` locator is "Bad locator" and exit 1.
+
+## The forms
+
+One new family, `lwtx`, in a new `tools/nlcapgen/matrix_lwtx.go`, built as `lwt` is: a verb axis (`add`) and a form axis per space, up to three duplicate adds per space, GW5's `d0` setup, and `ip` for every step. The modules list grows to `kwNhModules` plus `ila` and `xfrm_interface`, so no row autoloads a module mid-batch.
+
+"rc" is the generator's expectation. LF2-T01's rule holds: the first capture confirms or corrects it, and any correction goes in the decision log. Below, `P6` is `-6 route add 2001:db8:2::/64`, `S1` is `2001:db8:9::1` and `S3` is `2001:db8:9::1,2001:db8:9::2,2001:db8:9::3`.
+
+| space | form | cmd (after `ip`) | rc | sends |

+That is 56 forms: 32 at rc 0, 11 at rc 2, 1 at rc 1 and 12 at rc 255. The `ioam6` and `rpl` forms share one space, `lwtxreq`, so there are eight spaces. `deriveDupGone` adds up to three duplicates in each space with rc 0 forms, which comes to 17.
+
+## Out of scope
+
+- **`bpf`.** It needs a program object, as `xdp` does, so it stays refused by design.
+- **Building the guest kernel with `IOAM6_LWTUNNEL` and `RPL_LWTUNNEL`.** That would mean a custom kernel for every VM flavor. The `ioam6` and `rpl` rows compare the request, which is goip's half; the kernel's answer is the same `EOPNOTSUPP` for both. If the kernel config changes, the rows' rc moves to 0, and the first capture after it records that.
+- **`End.BPF` and `seg6local`'s `endpoint`.** They load a BPF program, so they stay refused, as `bpf` does.
+- **`ila`'s uninitialized groups.** goip sends zeros (see [the quirks](#ips-quirks-goip-copies)). No form uses fewer than four groups, since the bytes `ip` sends there are whatever is on the stack.
+- **`seg6`'s 1023-byte `segs` cut.** goip cuts at the same length. No form reaches it. The cut is inside the route bound: 26 segments written out in full (`2001:0db8:0000:…`, 40 characters each) pass 1023 bytes with a 424-byte SRH, and `ip` installs the route with the last segment cut (`docs/netlink/upstream/iproute2-lwtunnel-encap-parsing.md`, not committed, bug 4). (Corrected after the plan closed; this said the cut was past the bound.)
+- **Moving the existing families**, as in [goip-live-forms.md](goip-live-forms.md#out-of-scope).
+
+## Gates every task inherits
+
+[goip-lwt-encap.md's gates](goip-lwt-encap.md#gates-every-task-inherits), and:
+- **One SRH builder.** `seg6`, `seg6local`'s `srh` and, with its own header, `rpl` share the segment-list parser, so the last-to-first order and the comma count are written once.
+- **The quirks are tested.** Each item in [`ip`'s quirks](#ips-quirks-goip-copies) has a row in a goip table and a form in the `lwtx` family.

+
+### LX1 — the encoder
+
+#### LX1-T01 the SRv6 encodings
+
+A new `pkg/xtcpnl/xtcpnl_lwt_seg6.go`:
+- **`SRH(segs [][16]byte, hmac uint32, encap bool)`** gives `parse_srh`'s bytes;
+- **`Seg6Encap`** (mode, the SRH, an optional `tunsrc`) and **`Seg6LocalEncap`** (the attributes in argv order, the counters, the flavors, an optional SRH);
+- **`LwtEncap`** gains `Seg6` and `Seg6Local`, and `PutLwtEncap` writes them.
+
+`TestPutSeg6Encap` (`xtcpnl_lwt_seg6_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: one segment, `encap` | `S1`, mode 1 | `SRH`{mode 1; `hdrlen` 2, type 4, `segments_left` 0, `first_segment` 0; `S1`}, as a hand-built golden |
+| positive: three segments, last to first | `S3`, mode 1 | `segments[0]` = `2001:db8:9::3`, `segments[2]` = `S1` |
+| positive: `inline` adds a zero segment | `S1`, mode 0 | two segments, `segments[0]` zero, `segments_left` 1 |
+| positive: `hmac` | `S1`, `hmac` 7 | flag 0x08, TLV type 5 length 38 `hmackeyid` be32 7, 32 zero bytes |
+| positive: `tunsrc` | `S1`, `tunsrc` set | `SRH`, then `SRC` (2), 16 bytes |
+| positive: `seg6local` in argv order | `ACTION`, `NH6`, `OIF`, `count` | the four in that order; `COUNTERS` a nest of three u64 0 |
+| positive: `next-csid` with both lengths | `lblen` 32 `nflen` 16 | `FLAVORS`{`OPERATION` 0x10, 32, 16} |
+| negative: no `tunsrc` | `S1` | no `SRC` |
+| boundary: mode −1 | no `mode` | `mode` bytes `ff ff ff ff`, one zero segment |
+| boundary: the builder one byte short | a buffer one byte under | `ErrAttrNoSpace`, nothing half-written |
+| corner: `End.B6`'s SRH | `encap` false | the extra zero segment, as `inline` |
+| corner: `End.B6.Encaps`' SRH | `encap` true | no extra segment |
+
+**Mutation check:** the segments written first to last; `segments_left` as `nsegs`; the HMAC flag left out; the `SRH` written before `seg6local`'s other attributes.
+
+#### LX1-T02 `ila`, `xfrm`, `ioam6` and `rpl`
+
+A new `pkg/xtcpnl/xtcpnl_lwt_other.go`: `IlaEncap`, `XfrmEncap`, `Ioam6Encap` and `RplEncap`, which `LwtEncap` and `PutLwtEncap` take.
+
+| description | input | expected |
+|---|---|---|
+| positive: `ila`'s locator | `2001:0:0:2` | `LOCATOR` bytes `20 01 00 00 00 00 00 02` |
+| positive: `ila`'s u8s in argv order | `hook-type`, then `csum-mode` | `HOOK_TYPE`, then `CSUM_MODE` |
+| positive: `xfrm` | `if_id` 1, `link` 3 | `IF_ID` u32 1, `LINK` u32 3 |
+| positive: `ioam6` inline | the "trace alone" form | `FREQ_K` 1, `FREQ_N` 1, `MODE` 1, `TRACE` {`00 01`, 0, 3, `80 00 00 00`} |
+| positive: `ioam6` encap | `SRC` and `DST` set | `SRC` before `DST`, both before `TRACE` |
+| positive: `rpl` | two segments | `hdrlen` 4, type 3, `segments_left` 2, the segments last to first |
+| negative: `ioam6` inline drops `SRC` and `DST` | inline, with both set | neither written |
+| boundary: `ioam6`'s largest `size` | 244 (`IOAM6_TRACE_DATA_SIZE_MAX`) | `remlen` 61, byte 3 `0x3d` |
+| corner: `ioam6`'s 24-bit type | `0xabcdef` | `ab cd ef 00` |
+
+**Mutation check:** the locator little-endian; `remlen` as `size`; `ioam6`'s `DST` written for inline.
+
+### LX2 — the parsers and the three places
+
+#### LX2-T01 `lwtEncapArgs` for the six types
+
+`lwtEncapArgs` reads each type as `ip` does, including [the quirks](#ips-quirks-goip-copies). Because a route, a hop and a nexthop object all call it, all three get the types at once. A route's and a nexthop's 1024-byte bound, and a hop's 4096, apply unchanged.
+
+`TestLwtEncapArgsSrv6` (`lwt_encap_args_srv6_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: each form's argv | the forms table's encap words | the `LwtEncap` its "sends" column says, and the index of the last encap word |
+| positive: `seg6`'s `hmac` before `mode` | `hmac 1 mode encap segs S1` | accepted, `hmac` 1 |
+| negative: `segs` before `mode` | `segs S1 mode encap` | `"segs" provided before "mode"`, `ErrInvalidArgument` |
+| negative: `tunsrc` with `inline` | the form | `"tunsrc" invalid with inline mode` |
+| negative: a second `segs` | `mode encap segs S1 segs S1` | `duparg2("segs", …)` |
+| negative: `seg6local` with no action | `table 100` | "Missing action type", exit 255 |
+| negative: `ioam6` out of order | `mode encap freq 1/2 …` | `missarg("trace")` |
+| negative: `ila`'s five groups | `2001:0:0:2:3` | "Bad locator", exit 1 |
+| negative: `xfrm`'s `if_id 0` | the form | `"if_id" value is invalid` |
+| negative: `End.BPF` and `endpoint` | `action End.BPF endpoint …` | `ErrNotImplemented` |
+| boundary: `ioam6`'s `size` 4 and 244 | both | accepted; 248 is "Trace size is too big" |
+| boundary: `freq` `k` = `n` | `freq 5/5` | accepted; `6/5` refused |
+| corner: `xfrm` swallows the rest | `if_id 1 dev d0` | the index past `d0`, no `OIF` |
+| corner: `ioam6`'s trace at the end of argv | `… size 12` last | the index on `12`, so the caller reads it again |
+| corner: `seg6local`'s `srh segs S` at the end | the form | the index on `S` |
+| corner: `hmac x` | `seg6` and `seg6local` | `hmac` 0 |
+| corner: `seg6local`'s `flavors next-csid` alone | then `dev d0` | `OPERATION` 0x10, no lengths, stops before `dev` |
+| corner: `bpf` | `bpf in obj …` | `ErrNotImplemented`, as now |
+
+**Mutation check:** `xfrm` given an `else break`; `ioam6`'s end-of-argv step back dropped; `seg6local`'s `srh` index off by one.
+
+#### LX2-T02 the three places
+
+No new code is expected, since all three call `lwtEncapArgs`. This task checks it, and fixes whatever doesn't hold.
+
+| description | input | expected |
+|---|---|---|
+| positive: a route's `seg6` | the `seg6route6` forms | `RTA_ENCAP`, `RTA_ENCAP_TYPE` 5 where the keyword is |
+| positive: a hop's `seg6` | the `lwtxhop` forms | the encap inside the first `rtnexthop`, after `RTA_GATEWAY` |
+| positive: a nexthop's `seg6` and `seg6local` | the `lwtxnh` forms | `NHA_ENCAP`, `NHA_ENCAP_TYPE` 5 and 7 |
+| boundary: a `seg6` SRH at the route bound | segments to 1024 bytes, then one more | built, then refused with `addraw_l`'s message, where `ip` prints it and sends the route without the encap ([goip-lwt-encap-status.md](goip-lwt-encap-status.md)'s decision log) |
+| corner: `xfrm` in a hop | `nexthop via … encap xfrm if_id 1 dev d0` | `dev d0` swallowed, as on a route |
+
+**Done when:** both tables pass; O5's golden, regenerated, shows no row moved; lint-baseline and netlink-audit pass.
+
+### LX3 — the rows, the captures and the oracles
+
+#### LX3-T01 the `lwtx` family
+
+As [LE3-T01](goip-lwt-encap.md#le3-t01-the-lwt-family), for the forms table. `TestLwtxSpaces` checks each row's cmd and rc, the 56 forms and the duplicates, every setup step `ip`, the modules (with `ila` and `xfrm_interface`), and the same bytes twice.
+
+#### LX3-T02 capture
+
+As [LE3-T02](goip-lwt-encap.md#le3-t02-capture): two fresh-boot batches that agree, and `TestWsCorpusRows` over them. The first batch confirms each rc. The `ioam6` and `rpl` rows' `EOPNOTSUPP` and extack are recorded as they come.
+
+#### LX3-T03 O3 and O5
+
+- **O3:** `pkg/xtcpnl/xtcpnl_ws_lwtx_test.go` decodes each row's request and checks the encap against the row's `axes`: the type, the SRH's header and segments, `seg6local`'s attributes and nests, `ila`'s and `xfrm`'s scalars, and `ioam6`'s trace header.
+- **O5:** the eight spaces go in `wsO5Spaces`.
+
+| description | input | expected |
+|---|---|---|
+| positive: every form's encap | `TestWsLwtxCorpus` | each row's request as its axes |
+| positive: every new row `same` | `TestWsGoipDifferential` | the new rows `same`; no existing row moves |
+| positive: the u8 padding zeroed | `ila`'s and `ioam6`'s captured padding | zeroed before comparing, the values kept |
+| negative: an O3 row with the segments first to last | hand-built | the check fails |
+| negative: an O3 row with `remlen` as `size` | hand-built | the check fails |
+| corner: the quirk rows | `xfrm` swallowing, `ioam6`'s and `srh`'s end of argv | goip `same` as `ip`, sent or refused |
+| corner: a refusal at rc 255 | the twelve rc 255 rows | zero requests (O2), and goip refuses too |
+
+**Mutation check:** O3's segment order check dropped; O5's u8 padding left unzeroed in a `seg6local` nest.
+
+**Done when:** both tables pass; lint-baseline and netlink-audit pass.
+
+### LX4 — the matrix rows and the VM gate
+
+#### LX4-T01 the rows
+
+As [LE4-T01](goip-lwt-encap.md#le4-t01-the-rows): a form table for the `lwtx` spaces in `commands_gw_test.go`, and `gw_lwtx*` rows in `commands.go`, one per rc 0 and rc 2 form, 43 rows. The rc 255 forms stay O5-only, as in goip-lwt-encap.md, since goip exits 1, and so does the rc 1 `ila` form, since a GW row is rc 0 or 2 (`gwRcs`). The rows stay ungated until LX4-T02.
+
+#### LX4-T02 the VM gate
+
+As [LE4-T02](goip-lwt-encap.md#le4-t02-the-vm-gate): a `--section route,nexthop` run, twice clean, then the full run; then the rows are gated.
+
+**Done when:** both runs are clean, the rows are gated, and lint-baseline passes. It closes the plan.

+# goip ↔ `ip` write keywords: implementation status
+
+**Last updated:** 2026-11-03
+
+**Summary:**
+- The design and the task plan are in [goip-write-keywords.md](goip-write-keywords.md). This document tracks progress against them.
+- The plan is written (DOC001). It follows [goip-link-kinds.md](goip-link-kinds.md), whose KC0 to KG5 are done ([its status](goip-link-kinds-status.md), V246).
+- At 4da0e473 the workbench differential (`internal/goip/testdata/ws-differential.txt`) has 608 `refuses` rows, 0 `differs` and 0 `sends`. GW1 to GW4 close the 608 by object (route 331, link 190, nexthop 57, rule 30; DOC001 had link as 196, corrected at DOC002). GW5 adds the matrix rows.
+- GW1-T01 is done: goip sends `nhid` as `RTA_NH_ID`, and a route by id keeps universe scope. The 122 `nhid` rows are `same`; 486 rows refuse (V001–V003).
+- GW1-T02 is done: `pref` is `RTA_PREF` and `expires` `RTA_EXPIRES`. Of their 103 rows, 94 are `same` and 9 now stop at `nexthop`, which GW1-T04 builds; 392 rows refuse (V004–V006).
+- GW1-T03 is done: `tos`/`dsfield` is `rtm_tos`, `realms` `RTA_FLOW`, and `vrf` the VRF's table, looked up in the loop as `ip` does. Of their 20 rows, 18 are `same` and 2 `vrf` rows now stop at `nexthop`; 374 rows refuse (V007–V009).
+- GW1-T04 is done: multipath `nexthop` is `RTA_MULTIPATH`, its hops read after `RTA_OIF` with each hop's dev looked up as it is read. 95 of the 97 rows are `same`; 279 rows refuse (V010–V012).
+- **GW1 is closed** (DOC002). The route rows refuse only at a per-hop `encap ip`/`ip6` (2, fibt). GW2 is broken into eight tasks in the plan.
+
+- GW2-T01 is done: `set … address` runs `nl_get_ll_addr_len`'s get by index and checks the reply's address length. The 2 rows are `same`; 277 rows refuse (V013–V015).
+
+- GW2-T02 is done: `group` is `IFLA_GROUP`, with `rtnl_group_a2n`'s int truncation, and with no dev the group-wide set. Of its 61 rows, 1 is `same` and 60 now stop at a later GW2 keyword; 276 rows refuse (V016–V018).
+
+- GW2-T03 is done: the five GSO and GRO sizes are their `IFLA_*` u32s. Of the 96 rows stopping there, 50 are `same` and 46 now stop at a later GW2 keyword; 226 rows refuse (V019–V021).
+
+- GW2-T04 is done: `addrgenmode` is `IFLA_AF_SPEC{AF_INET6{IFLA_INET6_ADDR_GEN_MODE}}`, with the names compared as `strcasecmp` does. Of its 35 rows, 2 are `same` and 33 now stop at a later GW2 keyword; 224 rows refuse (V022–V024).
+
+- GW2-T05 is done: `protodown` is `IFLA_PROTO_DOWN` u8, and `protodown_reason` the nested mask and value, with `matches()` for its on/off word. The 20 rows are `same`; 204 rows refuse (V025–V027).
+
+- GW2-T06 is done: `broadcast`/`brd` is `IFLA_BROADCAST`, `carrier` `IFLA_CARRIER`, and `mode` and `state` `IFLA_LINKMODE` and `IFLA_OPERSTATE`, looked up in render's own name tables. 72 rows become `same` (all of `linkset`'s 69, and 3 in `linkattr`); 132 rows refuse, the link ones only at GW2-T07's and T08's keywords (V028–V030).
+
+- GW2-T07 is done: `xdp`, `xdpgeneric`, `xdpdrv` and `xdpoffload` with `off` or `none` as the last word are `IFLA_XDP` with fd -1, and `xdpoffload` looks dev up first. Any other form is a program load and stays not implemented. 13 rows become `same`; `xdp off carrier on` still refuses; 119 rows refuse (V031–V033).
+
+- GW2-T08 is done: `index` is `ifi_index` on a create and refused on a set, `link-netnsid` is `IFLA_LINK_NETNSID`, and `parentdev` is `IFLA_PARENT_DEV_NAME`. `netns` stays not implemented (decision log). The 3 rows are `same`; 116 rows refuse (V034–V036).
+- **GW2 is closed** (DOC003). The link rows refuse only at `netns` (26) and at an `xdp` that isn't last (1), both in the decision log. GW3 is broken into three tasks in the plan.
+
+- GW3-T01 is done: `hw_stats` is `NHA_HW_STATS_ENABLE` u32 through `parseOnOff`. The 41 rows are `same` (`nhgrp` 120 of 120); 75 rows refuse (V037–V039).
+
+- GW3-T02 is done: `dst_port` is refused by the chain's last arm, as `ip` 7.2.0 refuses an unknown word. The 12 rows are `same`; 63 rows refuse (V040–V042).
+
+- GW3-T03 is done: `encap mpls` is `NHA_ENCAP` (`NLA_F_NESTED`) with the label stack and an optional ttl, then `NHA_ENCAP_TYPE`; other encap types stay not implemented. The 4 rows are `same`; 59 rows refuse (V043–V045).
+- **GW3 is closed** (DOC004). No nexthop row refuses. GW4 is one task in the plan.
+
+- GW4-T01 is done: rule `realms` is `FRA_FLOW` through GW1-T03's `getRtRealmsOrRaw`. The 30 rows are `same` (`rule4` 203 of 203); 29 rows refuse (V046–V048).
+- **GW4 is closed** (DOC005). The 29 left are the 2 per-hop `encap ip`/`ip6` route rows and the 27 link rows the decision log lists. GW5 is broken into four tasks in the plan.
+
+- GW5-T01 is done: 11 route rows in goip-parity's matrix, one per route keyword form and `ip` rc the corpus has with an `ip`-only setup, each the workbench row's argv, setup and floor (V049–V051). Ten forms have no such row and are recorded in V049. The rows are ungated until GW5-T04.
+
+- GW5-T02 is done: 18 link rows, as GW5-T01's (V052–V054). Three forms have no row (the group-wide set, `xdpoffload`, `index` on a create), recorded in V052.
+
+- GW5-T03 is done: 6 nexthop and rule rows, as GW5-T01's (V055–V057). `encap mpls` has no row, since all four of its corpus rows run `sysctl`; the forms with no row are recorded in V055.
+
+- GW5-T04 is done: a `--section route,link,nexthop,rule` run (904 of 904 rows `PASS`) and then the full run (1281 of 1281) are clean, so the 35 GW rows are gated, and `TestUngatedSurfaceIsNotVacuous`' exception is gone (V058–V060).
+- **GW5 is closed, and with it the plan** (DOC006). The 29 rows left `refuses` in the O5 golden are the ones the decision log lists.
+
+**Next action:** none in this plan. The ip→goip work continues in [goip-lwt-encap.md](goip-lwt-encap.md) ([its status](goip-lwt-encap-status.md)). The next push needs the whole-repo `test-go-race` check, a clean full VM run and an explicit OK.

+
+## Update rules
+
+- States are `not started`, `in progress`, `blocked`, `done` or `deferred`. There are no percentages.
+- A task is `done` only when its "Done when" has passed and the evidence is in the [ledger](#verification-ledger).
+- Evidence IDs (`V###` for code and VM runs, `DOC###` for docs) are immutable and append-only.
+- Task IDs (`GWn-Tmm`) are never renumbered.
+- Every task's commit flips its own checklist row, appends its `V###` rows, and records the golden's `refuses` count after it.
+- A phase's last task also closes the phase, following [Closing a phase](goip-write-keywords.md#closing-a-phase).
+- A statement elsewhere in `docs/netlink/` that a task makes false is amended in that task's commit.

+| DOC001 | 2026-11-02 | plan | The plan and this status doc, from the golden's 608 `refuses` rows at 4da0e473 and `ip` 7.2.0's `iproute_modify`, `parse_nexthops`, `parse_one_nh`, `ipvrf_get_table`, `rtnl_dsfield_a2n` and `get_rt_realms_or_raw`. doccheck | task IDs one to one, the graph acyclic, no broken link or anchor | 65daee4b |
+| V001 | 2026-11-02 | GW1-T01 | `go vet ./internal/goip/...`, `go test -count=1 -race ./internal/goip/... ./internal/goipparity/...`; `go test ./internal/goip/ -run TestWsGoipDifferential -update-ws-o5` | all pass: `TestRouteWriteNhid` (17 rows; `TestParseRouteWriteArgs`' row loop is now `runRouteWriteRows`, shared, and loses its `nhid` refusal row). The golden: 608 `refuses` to 486, all 122 `nhid` rows `same` (route4 39, route6 10, fibnh 71, fibt 2); `differs` and `sends` 0 in every family | this commit |
+| V002 | 2026-11-02 | GW1-T01 | mutation in a scratch worktree, each `go test -run TestRouteWriteNhid` under `systemd-run --user --scope -p MemoryMax=6G`, `-timeout=180s`: the id in base 10; scope left at link; `nhid 0` counted as present; the attribute moved first | 4 of 4 killed: by the hex row; the IPv4 unicast rows; the id-0 and last-id rows; every row | this commit |
+| V003 | 2026-11-02 | GW1-T01 | `nix build .#checks.x86_64-linux.lint-baseline`, then `.#checks.x86_64-linux.netlink-audit`, in a scratch worktree holding only the task's diff | both pass; the first lint run found `rangeValCopy` on the shared row loop, fixed by indexing | e9a397d9 |
+| V004 | 2026-11-02 | GW1-T02 | as V001 | all pass: `TestRouteWritePrefExpires` (23 rows). The golden: 486 `refuses` to 392; of the 103 `pref` and `expires` rows, 94 `same` and 9 refusing at a later `nexthop` (route6 9), so `nexthop` refusals go from 86 to 95; `differs` and `sends` 0 in every family | this commit |
+| V005 | 2026-11-02 | GW1-T02 | mutation, as V002, `-run TestRouteWritePrefExpires`: `low` as 1; `pref` as `strcmp`; `pref` before `metric` in the chain; a negative expiry accepted; the names folded to lower case | 5 of 5 killed: by `pref low`; `pre high`; `p 7` and `pr 7`; `-1` and `x`; `Low`. A first order mutant, `pref` before `preference`, survived as an equivalent: `preference` can't match `pref`'s prefix test, so the order between them changes nothing | this commit |
+| V006 | 2026-11-02 | GW1-T02 | as V003 | both pass first time | 51238854 |
+| V007 | 2026-11-02 | GW1-T03 | as V001, with `go test -count=1 ./internal/goip/service/ -run TestVRFTable` | all pass: `TestRouteWriteTosRealmsVrf` (23 rows), `TestVRFTable` (9 rows: the one get by name with no ext mask, a vrf's `IFLA_VRF_TABLE`, 0 for another kind or no device, 254 for `default` with `ENODEV`), and the rule writer's tos rows unchanged. `TestParseRouteWriteArgs` loses its `vrf`, `tos` and `realms` refusal rows, and its row loop takes a fake VRF lookup whose calls list beside dev's. The golden: 392 `refuses` to 374; the 5 `dsfield` rows and 13 of the 15 `vrf` rows `same` (fibt), and 2 `vrf` rows refusing at a later `nexthop`, so `nexthop` refusals go from 95 to 97; `differs` and `sends` 0 in every family | this commit |
+| V008 | 2026-11-02 | GW1-T03 | mutation, as V002: tos in base 10; the realm halves swapped; `tableOK` cleared after `vrf`; the get with ext mask 1 (`-run TestVRFTable`); `default` not mapped (`-run TestVRFTable`) | 5 of 5 killed: by the hex, `dsfield 10`, `0xff` and `ds` rows; the three realm rows; the local-route row; all 9 rows; the default row | this commit |
+| V009 | 2026-11-02 | GW1-T03 | as V003 | both pass; the first lint run found gofmt on `routeParseState`'s field alignment after `vrfTable` was added, fixed | 986e62b7 |
+| V010 | 2026-11-02 | GW1-T04 | as V001, with `go test -count=1 -race` over every package importing `pkg/xtcpnl` (its `RouteWrite` gains `Nexthops`) | all pass: `TestRouteWriteMultipath` (24 rows), `TestEncodeRouteMultipath` (9 rows), and a `TestBuildRouteWriteRequestMetricsNest` row for `RTA_MULTIPATH` after `RTA_METRICS`. `TestParseRouteWriteArgs` loses its `nexthop` refusal row, and `TestRunRouteWrite`'s unimplemented keyword is now `encap`. `pkg/xtcp`'s test binary doesn't link locally (giouring, as before) and runs under the nix check. The golden: 374 `refuses` to 279; 95 of the 97 `nexthop` rows `same` (route4 19, route6 19, fibt 56, fibnh 1), and 2 refusing at a per-hop `encap` (fibt); `differs` and `sends` 0 in every family | this commit |
+| V011 | 2026-11-02 | GW1-T04 | mutation, as V002: `rtnh_hops` as the weight; `RTA_MULTIPATH` before `RTA_METRICS` (`-run TestBuildRouteWriteRequestMetricsNest`); `rtnh_len` counting only the first attribute (`-run TestEncodeRouteMultipath`); `RTA_GATEWAY` for any family; the scope rule unchanged; the hops parsed before the route's dev; `weight` by prefix | 7 of 7 killed: by the weight, hex-weight and delete rows; the multipath-after-metrics row; the RTA_FLOW and RTA_VIA rows; the via-inet row; every universe-scope row; the two dev-order rows; the `weigh` row | this commit |
+| V012 | 2026-11-02 | GW1-T04 | as V003 | both pass; the first lint run found goconst on `"encap"`, which `tnlKeyEncap` already names, in route_write.go and nexthop_write.go, fixed. The whole-repo `nix build .#checks.x86_64-linux.test-go-race` passes at acbabfef | acbabfef |
+| DOC002 | 2026-11-02 | GW1 close | The phase closed as the plan's [Closing a phase](goip-write-keywords.md#closing-a-phase): GW2 broken into GW2-T01 to T08 with their tables, from `ip` 7.2.0's `iplink_parse`, `iplink_modify`, `nl_get_ll_addr_len`, `xdp_parse`, `rtnl_group_a2n`, `protodown_reason_a2n`, `get_operstate` and `parse_on_off`; the inventory's remaining count; route-write-path.md's multipath statements amended. doccheck | task IDs one to one, the graph acyclic, no broken link or anchor | acbabfef |
+| V013 | 2026-11-02 | GW2-T01 | as V001 | all pass: `TestLinkWriteAddrLen` (13 rows) and `TestLinkInfoDataByIndex` (7 rows). `TestBuildLinkWrite`'s row loop is now `runLinkWriteRows`, shared, with a fake get by index whose calls list beside the names, and it loses its address-length refusal row. The golden: 279 `refuses` to 277, the 2 `set address` rows `same` (linkset); their by-index gets match `ip`'s bytes; `differs` and `sends` 0 in every family | this commit |
+| V014 | 2026-11-02 | GW2-T01 | mutation, as V002: the length check as `>=`, and as `<=`; the get with ext mask 1 (`-run TestLinkInfoDataByIndex`); a refused get returned rather than skipped; the check on add; dev looked up again after the check; the linkinfo walk resetting the address (`-run TestLinkInfoDataByIndex`); the family of the get as `AF_UNSPEC` | 8 of 8 killed: by the short and one-byte rows; the long row; 4 of the 7 rows; the refused-get row; the add row; 4 rows, by their lookup lists; the address-and-kind row; the `-6` row. The first refused-get mutant didn't compile and was rewritten | this commit |

+| V016 | 2026-11-02 | GW2-T02 | as V001 | all pass: `TestLinkWriteGroup` (21 rows) and `TestCStrtol` (14 rows). `TestBuildLinkWrite`'s `group` refusal row becomes a `carrier` one, still refused until GW2-T06. The golden: 277 `refuses` to 276; of the 61 `group` rows 1 `same` and 60 refusing at a later GW2 keyword (gso/gro 96 in all, broadcast 16, mode 5, state 2); `differs` and `sends` 0 in every family | this commit |
+| V017 | 2026-11-02 | GW2-T02 | mutation, as V002: the long not truncated to an int; `duparg` dropped; `default` by prefix; the group-wide create allowed; the group-wide kind kept; base 10; the group-wide path dropped | 7 of 7 killed: by the 2^32 and 2^32+5 rows; the second-group row; `group def`; the create row; the dropped-type row; the hex and octal rows; the four group-wide rows. The first truncation mutant didn't compile and was rewritten | this commit |

+## Decision log
+
+- **One plan for the O5 refusals, not more phases in goip-link-kinds.** That plan's tiers were captures, parsers and goip per link kind. These rows are keywords across four objects whose captures and parsers already exist, so the tiers collapse to one phase per object. goip-link-kinds' status doc stays closed at V246.
+- **The O5 golden is the replay table.** Every task regenerates `ws-differential.txt`, and its row movement from `refuses` to `same` is the task's main evidence. The table tests add the boundaries and the abbreviations the generated rows don't reach.
+- **GW1-T01's mutant row is the IPv4 one, not the IPv6 one the plan named.** An IPv6 route is universe scope whatever its next hop, so only an IPv4 unicast by id shows the scope rule; the plan's text is corrected.
+- **GW1-T02's order mutant is `pref` before `metric`, not before `preference`.** The plan's mutant is equivalent (V005); the one that matters is `p` and `pr`, which `priority` takes because the chain tests it first. A `p 7` row is added, and the plan's text is corrected.
+- **GW1-T03's lookup is a callback beside `resolve`, not a second resolver type.** `ip` calls `ipvrf_get_table` in the loop and `ll_name_to_index` for dev after it, so the order is part of parity. The row runner's fake lists both in one call log, which lets a row assert the get goes first.
+- **The plan's "15 `vrf` rows `same`" was 13.** Two (`ipv4_mpath_oif_vrf_test-003` and its IPv6 twin) carry a `nexthop` after `vrf`; they now refuse there and move to GW1-T04's count, which is 97.
+- **A per-hop `encap` or `as` is refused, not built.** goip has no lwt encoder. GW3's `nexthop encap mpls` is the first one the plan builds, and the 2 route rows here use `encap ip`/`ip6`, a different type. They stay `refuses` until a later plan or task builds `ip`'s `lwt_parse_encap` for them.
+- **The link count was 190, not 196.** DOC001's split summed to 614 against its own total of 608; the inventory table's link rows sum to 190, and so does the golden. The status summary and GW2's phase row are corrected.
+- **coverage-status.md's O5 table is left as W2c's snapshot.** It records that task's counts, not the current ones, which are in the golden and in this document.
+- **GW2-T01 reuses the tunnel prefetch's get.** `nl_get_ll_addr_len` sends the same 32 bytes as `LinkInfoDataByIndex`, so the check takes the `fetch` callback the tunnel parsers already have, rather than a second callback for the same request.
+- **dev's index from the check is kept for `finish`.** `ll_name_to_index` caches a hit, so `ip` sends one get by name for both. A miss isn't cached in either, so a missing device costs two gets in both.
+- **The group-wide set is built, not refused.** The plan had `group` with no dev as `ErrNotImplemented`. It is `iplink_parse`'s early return with the request as the loop left it, so goip sends that request: `ifi_index` 0 and `IFLA_GROUP`.
+- **`strcasecmp` is an ASCII fold, not `strings.EqualFold`.** `ip` runs in the C locale, where only ASCII letters fold; `EqualFold` also takes U+017F for `s` and the Kelvin sign for `k`, so `addrgenmode ſtable_secret` would be sent where `ip` refuses it. GW2-T04 adds `cStrcaseEq` and uses it. `ll_proto.go`'s `EqualFold` and `obj_l2tp.go`'s `strings.ToLower` have the same gap; it is left to a task that touches them.
+- **`protodown_reason` takes numbers only.** `protodown_reason_a2n` looks names up in `protodown_reasons.d`, which iproute2 doesn't ship, so with the stock files a name is refused; goip refuses it the same way.
+- **`mode` and `state` read render's tables.** `get_link_mode` and `get_operstate` compare against the names `ip` prints, so goip looks them up in `render`'s `linkModes` and `operStates` (as copies) rather than keeping a second list.
+- **`xdp` builds the detach only.** `xdp_parse` deletes for `off`/`none` as argv's last word and otherwise loads a BPF object, which goip doesn't do; that path is `ErrNotImplemented` and the golden's one row for it (`xdp off carrier on`) stays `refuses`.
+- **`netns` isn't built, so GW2 closes with 26 `netns` rows refusing.** `ip` opens `/run/netns/NAME` or `/proc/PID/ns/net` and sends the descriptor's number. goip writes the request to `GOIP_WRITE_OUT` for something else to send, so a descriptor it opened would be closed, and its number meaningless, by then. 25 of the rows also use `$$`, the capturing shell's pid, which no replay can reproduce. The plan's GW2-T08 had `netns` built; this replaces that, and the plan's out-of-scope list now says so. `link-netns` stays not implemented for the same reason, and a create whose lower `link` would be looked up in a `link-netnsid` namespace is refused as not implemented too.
+- **`index` on a set is always refused.** `iplink_modify` allows it only with `netns`, which goip doesn't build, so the refusal is `ip`'s whenever goip gets that far.
+- **`encap` builds `mpls` only.** `lwt_parse_encap` has ten types; the 4 nexthop rows use `mpls`, so the others stay `ErrNotImplemented`, after `ip`'s own checks on the type word and `missarg`, which every type shares. The 2 route rows with a per-hop `encap ip`/`ip6` still refuse; `xtcpnl.PutMplsEncap` takes the two attribute types so the route writer can reuse it.
+- **GW5 samples the moved rows rather than taking all 555.** The O5 golden compares every one offline against its capture. The matrix's job is the live `ip`-against-goip check in the VM, and one row per keyword form and rc does that without a VM run several times longer than KG4-T09's.
+- **A GW row's slug maps `-` to `_` as well as `/`.** `TestCommandTable` allows `[a-z0-9_]` only, and the workbench ids have dashes (`pw-023`), so `route4/pw-023` is `gw_route4_pw_023`; the plan's text is corrected.
+- **A row whose argv a picked row already has is passed over.** `Name` is the allowlist key, so two rows with one argv can't both be in the table. `route4/dup-2` and `route6/dup-2` repeat their `ec-006`'s add to meet `EEXIST`; IPv6's form takes `gone-3` instead, and IPv4 blackhole's has no rc 2 row. The plan adds this to its selection rule.
+- **The GW rows are ungated until GW5-T04, and `TestUngatedSurfaceIsNotVacuous` excepts them by slug.** The plan gates them only after the VM runs; the exception came out with the gating at GW5-T04.
+- **GW5-T04 runs the four sections once together, then the full run, rather than each section twice.** The full run runs every section again, so each section has two consecutive clean runs, and it is the full run the push needs as well. Four section runs twice over would be about 75 minutes each for no extra coverage. The plan's T04 table is corrected.
+- **The offline comparator reads a GW row's own workbench capture.** `corpusWriteRow` maps a `gw_` slug back to its `ws/` directory, so `TestCompareWriteRow`'s every-write-row pass covers them as it does the other write rows.
+- **`encap mpls` has no live row.** Its four corpus rows are `fibnh` selftest rows whose `pre` runs `sysctl`, and the plan's rule passes such rows over rather than giving them a new setup. The O5 golden still compares all four offline, and `TestNexthopWriteEncapMpls` holds the one-label, two-label, `ttl` and IPv6 forms.
+- **Names from config files are the stock files' names only.** goip reads no `rt_dsfield`, `rt_realms` or `group` file, so it takes the numeric forms and the names iproute2 7.2.0 ships, as with `rt_tables`.

+# goip ↔ `ip` parity: the write keywords goip refuses
+
+## Status
+
+**Last updated:** 2026-11-03
+
+**Summary:**
+- [goip-link-kinds.md](goip-link-kinds.md) is finished: KC0 to KG5 are closed, and goip-parity's table is 1246 rows.
+- The nlcap workbench's differential oracle (O5, `TestWsGoipDifferential`, the golden `internal/goip/testdata/ws-differential.txt`) runs every generated row's argv through goip and compares the request with `ip`'s capture. At 4da0e473 it reports 608 rows where goip says `object recognized but not implemented`. There are 0 `differs` and 0 `sends`.
+- Every one of the 608 is a keyword that `ip` 7.2.0's parser takes and goip's chain lists as unsupported. This plan closes them, one keyword group per task, so that each row becomes `same`: the same request, or the same refusal at the same check.
+- The tiers of the earlier plans collapse here. The captures already exist (the workbench's `ws/` corpus), and the request encodings are attributes `pkg/xtcpnl` already parses. So each phase is goip's parser, its table tests, the O5 golden, and at the end goip-parity matrix rows and a VM run.
+
+**Progress** is tracked in [goip-write-keywords-status.md](goip-write-keywords-status.md): the next action, the phase states, the task checklist, the verification ledger and the decision log. This document changes only when a task refines its own plan, or when a phase close expands the next phase.

+## Reference sources

+- **`ip` is 7.2.0** (`nix/upstream-pins.json`). Read it with `git -C ~/Downloads/iproute2 show v7.2.0:ip/<file>`. Line numbers here are from `v7.2.0`.
+- **The rows** are the workbench's, `nix/microvms/workbench/*.rows.jsonl`. Their captures are in `pkg/xtcpnl/testdata/7_3_0/ws/<family>/<id>/`: `cmd.json`, `ip.pcap`, `ip.rc`, `ip.err`, `dump.out` and the readbacks. They were recorded on the 7.3.0 guest kernel.
+- **The oracle** is `internal/goip/ws_differential_test.go`. Regenerate its golden with `go test ./internal/goip/ -run TestWsGoipDifferential -update-ws-o5`. Its classes:
+  - `same`: the same request, or both refuse at a check goip implements;
+  - `refuses`: goip returns `ErrNotImplemented`, whatever `ip` did;
+  - `sends`: goip writes a request `ip` refused to send;
+  - `differs`: both send, and the requests differ.
+- All of these trees are read-only inputs, as in [goip-parity-gaps.md](goip-parity-gaps.md#reference-sources).
+
+## The refusal inventory
+
+The 608 rows at 4da0e473, by the keyword goip stops at. "rc" is `ip`'s exit status: 0 the kernel accepted, 2 the kernel refused, 1 or 255 `ip` refused before writing (22 is `ip link`'s errno exit).
+
+| object | keyword | rows | families | `ip`'s parse site (`v7.2.0`) | sends |
+|---|---|---|---|---|---|

+| nexthop | `hw_stats` | 41 | nhgrp 39, nh4 1, nh6 1 | `ip/ipnexthop.c:1131` | `NHA_HW_STATS_ENABLE` u32 |
+| nexthop | `dst_port` | 12 | fibnh 10, nh4 1, nh6 1 | not a 7.2.0 word (iproute2 `ad2b2d95` adds it) | nothing: `ip` refuses, 255 |
+| nexthop | `encap` | 4 | fibnh | `:1095` | `NHA_ENCAP`, `NHA_ENCAP_TYPE` |
+| rule | `realms` | 30 | rule4 | `ip/iprule.c:1050` | `FRA_FLOW` u32 |
+
+By object: route 331, link 190, nexthop 57, rule 30.
+
+**Remaining after GW1** (DOC002): 279. These are route 2 (`fib_notify_test-001` and `fib6_notify_test-001`, a per-hop `encap ip`/`ip6`, which goip has no lwt encoder for), link 190, nexthop 57 and rule 30.
+
+**Remaining after GW2** (DOC003): 116. These are route 2 (as above), link 27, nexthop 57 and rule 30. The link 27 are all `linkattr`: 25 `netns $$` rows, `netns nosuch`, and `xdp off carrier on`, an `xdp` that isn't argv's last word and so is a program load. None of them is a keyword GW3 to GW5 build; they are in the decision log.
+
+**Remaining after GW3** (DOC004): 59. These are route 2 and link 27 (as above), and rule 30. No nexthop row refuses.
+
+**Remaining after GW4** (DOC005): 29. These are route 2 and link 27, as above. Of the 608, 579 rows are `same`: 555 with `ip` rc 0 or 2, and 24 that `ip` refused before sending (rc 1, 22 or 255).
+
+## Out of scope
+
+- **Anything outside the 608.** The plan follows the oracle. A keyword no workbench row uses (route `as`, `encap` at the top level, `ttl-propagate`, link `vf`, `xdpgeneric` with a program) stays `ErrNotImplemented` until a row exercises it.
+- **Names from config files.** goip reads none. Where `ip` reads `rt_dsfield`, `rt_realms` or `group`, goip takes the numeric forms and the stock files' names, as it already does for `rt_tables` (`routeTableNames`). A row naming anything else is recorded in the decision log rather than matched.
+- **`xdp` with a program.** Only `xdp off` is in the rows. Loading an object needs libbpf, which goip doesn't link.
+- **`netns` and `link-netns`.** `ip` opens the namespace and sends the descriptor's number in `IFLA_NET_NS_FD`, or asks the kernel for an nsid with it. goip writes its request to `GOIP_WRITE_OUT` rather than sending it, so a descriptor it opened would be closed, and its number meaningless, by the time anything sends the bytes. Both stay `ErrNotImplemented` (GW2-T08's decision).
+
+## Gates every task inherits
+
+These are [goip-link-kinds.md's gates](goip-link-kinds.md#gates-every-task-inherits), with the O5 golden added:
+- **O5:** the task's rows move from `refuses` to `same` in `ws-differential.txt`, regenerated in the task's commit. `differs` and `sends` stay 0 in every family, and no row moves from `same` to anything else.
+- **Unit tests:** table tests in the writer's `*_write_test.go`, `go test -count=1 -race` over `./internal/goip/...` and `./internal/goipparity/...`, and `go vet`.
+- **Mutation checks** in a scratch worktree, each mutant under `systemd-run --user --scope -p MemoryMax=6G` with `-timeout=180s`.
+- **Nix checks, one per call,** in a scratch worktree holding only the task's diff: lint-baseline and netlink-audit, and before any push, the whole-repo test-go-race.
+- **VMs,** at each phase's matrix task: two clean `--section` runs before a row is gated, and one clean full run before any push.
+- **Docs:** the task's checklist row and its `V###` rows land in the task's commit.
+
+## Phases and tasks
+
+One phase per object, in the order of their row counts, and a last phase for the matrix:
+
+```text
+GW1 ──> GW2 ──> GW3 ──> GW4 ──> GW5
+```
+
+The phases share no code, so the order is for review rather than dependency. GW5 needs the others, since its matrix rows cover every keyword.
+
+Every task's tests are tables: description | input | expected, with positive, negative, boundary and corner rows. GW1 is planned in full below. Each later phase is broken into tasks, with their tables, when the phase before it closes.
+
+### Closing a phase
+
+As in [goip-link-kinds.md](goip-link-kinds.md#closing-a-phase). In the commit of a phase's last task:
+1. **Status:** every task in the phase is `done` with its `V###` IDs, the phase is `done` in **Phase states**, and **Last updated**, the summary and **Next action** are updated.
+2. **Inventory:** the [refusal inventory](#the-refusal-inventory) gets the phase's remaining count, and a `DOC###` ledger row names the commit.
+3. **Expand the next phase:** its checklist range row becomes one row per task, each with its test tables here. IDs already listed never change.
+4. **Decisions:** every exclusion, divergence or scope change goes in the decision log.
+5. **Cross-docs:** any statement in [coverage-status.md](coverage-status.md), [route-write-path.md](route-write-path.md) or elsewhere in `docs/netlink/` that the phase made false is amended.
+6. **Checks:** task IDs are one to one between this document and the checklist, the graph is acyclic, links and anchors resolve, and spelling is US.
+
+### GW1 — route keywords
+
+Four tasks, all in `internal/goip/route_write.go`'s `routeParseKeywords` (`iproute_modify`'s chain in its order). Each replaces a `routeArmUnsupported` with an arm, and leaves the chain's order, which decides abbreviations, as it is.
+
+**What `ip` does** (`ip/iproute.c` at `v7.2.0`):
+- **`nhid`** (`strcmp`, `:1461`): `get_u32` in base 0, else `invarg("\"id\" value is invalid\n")`, 255. It sends `RTA_NH_ID` u32 where it is read; a second `nhid` sends a second attribute. A route with `nhid` keeps universe scope: `iproute_modify`'s link-scope default needs `!gw_ok && !nhs_ok && !nhid` (`:1628`), and `nhid 0` counts as absent there.
+- **`pref`** (`matches`, `:1504`): `low`, `medium` and `high` by `strcmp` (`ICMPV6_ROUTER_PREF_LOW` 3, `MEDIUM` 0, `HIGH` 1), else `get_u8` in base 0, else `invarg("\"pref\" value is invalid\n")`. It sends `RTA_PREF` u8. `preference` is the metric's `strcmp` alias earlier in the chain, and `p` and `pr` are `priority`'s, so `pre` and `pref` are the shortest spellings that reach it.
+- **`expires`** (`strcmp`, `:1258`): `get_u32` in base 0, else `invarg("\"expires\" value is invalid\n")`. It sends `RTA_EXPIRES` u32. `ip` sends it for either family; the kernel uses it only for IPv6.
+- **`tos`** (`strcmp`) and **`dsfield`** (`matches`), `:1251`: `rtnl_dsfield_a2n`, a name from `rt_dsfield` or `strtoul` in base 16 up to 255, else `invarg("\"tos\" value is invalid\n")`. It sets `rtm_tos`. goip's rule writer has this parse already (`rtnlDsfieldA2N`, through `(*ruleWrite).tosArg`).
+- **`realms`** (`matches`, `:1449`): `get_rt_realms_or_raw`: `[FROM/]TO` through `rtnl_rtrealm_a2n`, the `FROM` half shifted 16, else `get_unsigned` in base 0, else `invarg("\"realm\" value is invalid\n")`. It sends `RTA_FLOW` u32. No route row uses it, but `parse_one_nh` does the same per hop, so the parse lands with T03 and is shared with T04.
+- **`vrf`** (`matches`, so `v` is `vrf`, since `via` is `strcmp`; `:1486`): `ipvrf_get_table` sends a get by `IFLA_IFNAME`, with `ifi_family` the `-4`/`-6` preference and no `IFLA_EXT_MASK`. It reads `IFLA_VRF_TABLE` from the reply's `INFO_DATA` when the kind is `vrf`, and returns 0 otherwise. A failed get of `default` with `ENODEV` is `main` (254). A 0 is `invarg("Invalid VRF\n")`, 255. The table then goes out as `table` does: `rtm_table` under 256, else `RT_TABLE_UNSPEC` and `RTA_TABLE` u32. It sets `table_ok`.
+- **`nexthop`** (`strcmp`, `:1458`) ends the keyword loop. After `RTA_OIF` and `RTA_METRICS`, `parse_nexthops` reads the rest of the line:
+  - Each hop must start with `nexthop`. Anything else is `Error: "nexthop" or end of line is expected instead of "<w>"`, and a bare `nexthop` at the end is `Error: unexpected end of line after "nexthop"`; both `exit(-1)`, 255.
+  - `parse_one_nh` (`:1018`) reads `via [FAMILY] ADDR` (`RTA_GATEWAY`, or `RTA_VIA` when the family differs), `dev` (`ll_name_to_index` in the loop, a get each; `nodev` returns -1, which is `Error: cannot parse nexthop`, 255, after `Cannot find device`), `weight` (`get_unsigned`, 1 to 256, sent as `rtnh_hops` = w − 1; else `invarg("\"weight\" is invalid\n")`), `onlink` (`RTNH_F_ONLINK` in `rtnh_flags`), `realms` (`RTA_FLOW`), `encap` (`lwt_parse_encap`) and `as [to] ADDR` (`RTA_NEWDST`). The first other word ends the hop.
+  - The attribute is `RTA_MULTIPATH`, sent only if a hop was read, after every keyword's attribute.
+  - With `nhs_ok` the route keeps universe scope, as with `nhid`.
+
+**Where goip stands.**
+- `routeArmUnsupported` covers `as`, `tos`, `dsfield`, `expires`, `realms`, `nexthop`, `nhid`, `vrf`, `pref`, `encap` and `ttl-propagate`.
+- `(*routeParseState).defaultScope` (`route_write.go:519`) keeps universe only for `gwOK` and says so: `nexthop and nhid would also keep universe; both are refused.`
+- `route_write_test.go:389`, `:395` and `:548` hold `nexthop` and `nhid` as `ErrNotImplemented` rows. Those rows change to the requests `ip` sends.
+
+#### GW1-T01 `nhid`
+
+**Code.**
+- `routeArmNhid`: `getU32` in base 0 (`cparse.go`, `get_u32`'s rules), `RTA_NH_ID` through `st.attr`, and `st.nhid` set when the value isn't 0.
+- `defaultScope`: universe also when `st.nhid`. The comment changes to name `nexthop` alone.
+
+`TestRouteWriteNhid` builds requests from argv, with a fake resolver:
+
+| description | input | expected |
+|---|---|---|
+| positive: a blackhole by id | `-4 route add blackhole 198.51.100.7/32 table 4294967295 nhid 10` | `RTA_TABLE` 4294967295, then `RTA_NH_ID` 10; scope universe |
+| positive: an IPv6 unicast by id | `-6 route add 2001:db8::/64 nhid 7` | `RTA_NH_ID` 7; scope universe, not link |
+| positive: a hex id | `nhid 0x10` | `RTA_NH_ID` 16 |
+| positive: the attribute in word order | `nhid 10 metric 5` and `metric 5 nhid 10` | `RTA_NH_ID` before `RTA_PRIORITY`, and after it |
+| negative: a word for the id | `nhid x` | 255; `Error: argument "x" is wrong: "id" value is invalid` |
+| negative: no value | `... nhid` | 255; `Command line is not complete. Try option "help"` |
+| boundary: the u32 limits | `nhid 4294967295`; `nhid 4294967296` | `RTA_NH_ID` 0xffffffff; 255, the invarg text |
+| boundary: id 0 | `-4 route add 198.51.100.0/24 nhid 0` | `RTA_NH_ID` 0; scope link, since 0 is absent to the default |
+| corner: two ids | `nhid 1 nhid 2` | two `RTA_NH_ID` attributes, 1 then 2 |
+| corner: a delete by id | `-4 route del 198.51.100.0/24 nhid 10` | `RTA_NH_ID` 10; scope nowhere, as every unicast delete |
+| corner: `nh` is no keyword | `nh 10` | the destination rule's `duparg2` refusal, as today |
+
+The workbench rows are the replay table: `TestWsGoipDifferential` with the regenerated golden, the 122 `nhid` rows `same`.
+
+**Mutation check:** the id parsed in base 10 (the hex row); scope left at link (the IPv4 unicast row; an IPv6 route is universe whatever its next hop); `nhid 0` counted as present (the id-0 row); the attribute moved to the end (the word-order row).
+
+**Done when:** the table passes under `go test -race`; the golden shows the 122 rows `same` with `differs` and `sends` still 0; each mutant is caught; lint-baseline and netlink-audit pass in a scratch worktree.
+
+#### GW1-T02 `pref` and `expires`
+
+**Code.** `routeArmPref`: the three names by `strcmp`, then `getU8` in base 0, into `RTA_PREF` u8. `routeArmExpires`: `getU32` in base 0 into `RTA_EXPIRES` u32.
+
+`TestRouteWritePrefExpires`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each name | `pref low`, `pref medium`, `pref high` | `RTA_PREF` 3, 0, 1 |
+| positive: a number | `pref 2` | `RTA_PREF` 2 |
+| positive: an expiry | `-6 route add 2001:db8::/64 dev d0 expires 30` | `RTA_EXPIRES` 30 |
+| positive: an IPv4 expiry is sent | `-4 route add 198.51.100.0/24 dev d0 expires 30` | `RTA_EXPIRES` 30, as `ip` sends it |
+| negative: a bad pref | `pref highest`; `pref 256` | 255; `Error: argument "highest" is wrong: "pref" value is invalid`; the same for 256 |
+| negative: a bad expiry | `expires -1`; `expires x` | 255; `Error: argument "-1" is wrong: "expires" value is invalid` |
+| boundary: the limits | `pref 255`; `expires 4294967295`; `expires 0` | `RTA_PREF` 255; `RTA_EXPIRES` 0xffffffff; `RTA_EXPIRES` 0 |
+| corner: the abbreviations | `pre high`; `preference 7`; `pr 7`; `p 7` | `RTA_PREF` 1; `RTA_PRIORITY` 7 for the other three |
+| corner: a prefix past the word | `prefe high` | `prefe` is the destination, `ip`'s refusal |
+| corner: a name is strcmp | `pref Low` | 255, the invarg text |
+
+The workbench rows: the 68 `pref` and 35 `expires` rows `same`.
+
+**Mutation check:** `low` as 1 (the names row); `pref` as `strcmp` (the `pre` row); `pref` before `metric` and `priority` in the chain (the `p 7` and `pr 7` rows); the names folded to lower case (the `Low` row); a negative expiry accepted (the `-1` row).
+
+**Done when:** as GW1-T01, with the 103 rows.
+
+#### GW1-T03 `tos`, `dsfield`, `realms` and `vrf`
+
+**Code.**
+- `routeArmTos`: `rtnlDsfieldA2N`, which the rule writer's `tosArg` already calls (the stock `rt_dsfield` names and base-16 numbers), into `rtm_tos`.
+- `routeArmRealms`: `getRtRealmsOrRaw`, the `FROM/TO` split over the stock `rt_realms` names (`cosmos` is 0), else base-0 `get_unsigned`, into `RTA_FLOW`. GW4's rule `realms` and GW1-T04's per-hop `realms` use it too.
+- `routeArmVrf`: a `vrfTable` callback beside `resolve`, `Service.VRFTable(family, name)` in `routeWrite`: the get by name, then `IFLA_VRF_TABLE` from the `vrf` kind's data, or 0. A 0 is `Invalid VRF`, 255. `default` with `ENODEV` is 254. The table then takes `table`'s path (`st.table`), and `tableOK` is set.
+
+`TestRouteWriteTosRealmsVrf`:
+
+| description | input | expected |

+
+The rule writer's tos rows pass unchanged.
+
+The workbench rows: the 5 `dsfield` and 15 `vrf` rows `same`, except those with a later `nexthop`, which then refuse there (2 of the `vrf` rows, V007).
+
+**Mutation check:** tos in base 10 (`dsfield 10`); the realm halves swapped (`realms 1/2`); `tableOK` not set by `vrf` (the local row); the vrf get with `IFLA_EXT_MASK` (the bytes of the get); `default` not mapped (the default row).
+
+**Done when:** as GW1-T01, with the 20 rows; the rule writer's tests also pass.
+
+#### GW1-T04 multipath `nexthop`
+
+**Code.**
+- `routeArmNexthop` stops the keyword loop and records where the hops begin. `finish` then appends `RTA_MULTIPATH` after `RTA_OIF` and `RTA_METRICS`, in `ip`'s order.
+- `parseNexthops` and `parseOneNh` follow `ip`'s two functions. Each hop is a `struct rtnexthop` (len, flags, hops, ifindex) followed by its attributes. `dev` resolves in the loop. `encap` in a hop reuses goip's nexthop writer's `lwt` encoder if one exists; if none, the hop is `ErrNotImplemented`, recorded in the decision log with its row count.
+- `defaultScope`: universe when a hop was read.
+
+`TestRouteWriteMultipath`:
+
+| description | input | expected |

+| corner: a delete with hops | `-4 route del ... nexthop via 192.0.2.1 weight 1` | the hop sent; scope nowhere |
+
+The workbench rows: the 86 `nexthop` rows `same`, or the ones with a per-hop `encap` listed in the decision log if the encoder isn't there.
+
+**Mutation check:** `rtnh_hops` as the weight (the weight rows); `RTA_MULTIPATH` before `RTA_METRICS` (the place row); the hop's `rtnh_len` without its `RTA_FLOW` (the realms row); `RTA_GATEWAY` for a different family (the via-inet row); the scope rule unchanged (the scope row).
+
+**Done when:** as GW1-T01, with the 86 rows. This closes GW1: the route rows in the golden have no `refuses` left except any recorded per-hop `encap`.
+
+### GW2 — link set keywords
+
+Eight tasks, all in `internal/goip/link_write.go`'s `linkParseKeywords` (`iplink_parse`'s chain in its order) and `(*linkParseState).finish` (`iplink_modify`'s checks after it). Each replaces a `linkArmUnsupported` with an arm.
+
+The 190 rows after GW1-T04's golden: 61 `group`, 16 `gso_max_segs`, 15 `gro_max_size`, 7 `gro_ipv4_max_size`, 6 `gso_ipv4_max_size`, 5 `gso_max_size`, 35 `addrgenmode`, 16 `protodown`, 4 `protodown_reason`, 6 `broadcast`, 5 `carrier`, 3 `mode`, 1 `state`, 3 `xdp`, 2 `set address`, 2 `netns`, and one each of `index`, `link-netnsid` and `parentdev`. goip stops at the first keyword it refuses, so a row that carries two moves from one task's count to a later one's. About 30 of the linkset rows also carry `address`, and reach T01's lookup once their first keyword is built. That's why T01 comes first.
+
+**What `ip` does** (`ip/iplink.c` at `v7.2.0`):
+- **`address` on `set`** (`iplink_modify`, `:1279`): with a dev, an address and no `NLM_F_CREATE`, `nl_get_ll_addr_len` looks the dev up (`ll_name_to_index`), then sends `RTM_GETLINK` by `ifi_index` with `ifi_family` the `-4`/`-6` preference and no attributes. It reads the reply's `IFLA_ADDRESS` length. A different length is `Invalid address length %d - must be %d bytes`, and `iplink_parse` returns -1, which exits 1. A failed get or a reply with no address skips the check.
+- **`group`** (`strcmp`, `:1102`): `duparg` on a second one. `rtnl_group_a2n` takes a name from `group` (stock: `default` is 0), else `strtol` in base 0 into an `int`, refused when negative. So 2147483648 wraps negative and is refused, and 4294967296 wraps to 0. A failure is `invarg("Invalid \"group\" value\n")`. It sends `IFLA_GROUP` u32. With no dev, `group` is the filter of a group-wide set (`:1299`), a different request.
+- **`gso_max_size`, `gso_max_segs`, `gro_max_size`, `gso_ipv4_max_size`, `gro_ipv4_max_size`** (all `strcmp`, `:1204`–`:1249`): `get_unsigned` in base 0, `gso_max_segs` at most `GSO_MAX_SEGS` (65535), else `invarg("Invalid \"<name>\" value\n")`. Each sends its `IFLA_*` u32.
+- **`addrgenmode`** (`matches`, `:1144`): `get_addr_gen_mode` by `strcasecmp`: `eui64` 0, `none` 1, `stable_secret` 2, `random` 3, else `invarg("Invalid address generation mode\n")`. It sends `IFLA_AF_SPEC` holding `AF_INET6` holding `IFLA_INET6_ADDR_GEN_MODE` u8. Neither nest has `NLA_F_NESTED`.
+- **`protodown`** (`strcmp`, `:1173`): `parse_on_off`, `IFLA_PROTO_DOWN` u8. **`protodown_reason`** (`strcmp`, `:1182`): `protodown_reason_a2n`, a name from `protodown_reasons.d` (none stock) or `strtoul` in base 0 below 32, else `invarg("invalid protodown reason\n")`. Then `on` or `off` by `matches`, else `on_off`'s error. It sends `IFLA_PROTO_DOWN_REASON | NLA_F_NESTED` holding `_MASK` (1 << reason) and `_VALUE` (the mask or 0), both u32.
+- **`broadcast`** (`matches`) and **`brd`** (`strcmp`), `:921`: `ll_addr_a2n`, the same parse as `address`, into `IFLA_BROADCAST`.
+- **`carrier`** (`strcmp`, `:1027`): `parse_on_off`, `IFLA_CARRIER` u8. A bad value returns `parse_on_off`'s `-EINVAL`.
+- **`mode`** (`strcmp`, `:1109`): `get_link_mode` by `strcasecmp`, `default` 0 or `dormant` 1, else `invarg("Invalid link mode\n")`, `IFLA_LINKMODE` u8. **`state`** (`strcmp`, `:1117`): `get_operstate` (`ip/ipaddress.c:150`), the `oper_states` names by `strcasecmp`, else `invarg("Invalid operstate\n")`, `IFLA_OPERSTATE` u8.
+- **`xdp`, `xdpgeneric`, `xdpdrv`, `xdpoffload`** (`strcmp`, `:949`): `xdp_parse` (`ip/iplink_xdp.c`). When `off` or `none` is the last word of argv, `xdp_delete` sends `IFLA_XDP` (no `NLA_F_NESTED`) holding `IFLA_XDP_FD` -1 and `IFLA_XDP_FLAGS`. The flags are `XDP_FLAGS_UPDATE_IF_NOEXIST` (1) without `-force`, with `SKB_MODE` (2) for generic, `DRV_MODE` (4) for drv and `HW_MODE` (8) for offload. Anything else loads a BPF object. `xdpoffload` looks the dev up first.
+- **`index`** (`strcmp`, `:904`): `duparg` on a second one. `atoi`, then `invarg("Invalid \"index\" value")` unless it is positive. On `set` with no `netns`, `iplink_modify` refuses: `index can be used only when creating devices or when moving device to another netns.`, `exit(-1)`.
+- **`netns`** (`strcmp`, `:964`): `duparg` on a second one. `netns_get_fd` opens `/run/netns/NAME`, else `/proc/PID/ns/net`, else `invarg("Invalid \"netns\" value\n")`. It sends `IFLA_NET_NS_FD` with the descriptor's number.
+- **`link-netnsid`** (`matches`, `:1164`): `duparg("link-netns/link-netnsid")` against either, `get_integer` in base 0, else `invarg`, `IFLA_LINK_NETNSID` s32.
+- **`parentdev`** (`strcmp`, `:1250`): `IFLA_PARENT_DEV_NAME`, the name with its NUL.
+
+#### GW2-T01 the `set address` length lookup
+
+**Code.** `finish` replaces its refusal with `checkAddrLen`: dev's index, then the get by index through the tunnel prefetch's `fetch` callback (`Service.LinkInfoDataByIndex`, whose reply now records `IFLA_ADDRESS`'s length). A different length is `Invalid address length N - must be M bytes`, exit 1.
+
+`TestLinkWriteAddrLen`:
+
+| description | input | expected |
+|---|---|---|
+| positive: a matching length | `set dev d0 address 02:00:00:00:00:aa`, d0 a 6-byte device | d0's lookup, the get by index, then `IFLA_ADDRESS` 6 bytes |
+| positive: a multicast address is sent | `address 01:00:00:00:00:01` | the request; the kernel's refusal is not goip's |
+| negative: a short address | `address 02:00` | 1; `Invalid address length 2 - must be 6 bytes`, no request |
+| negative: a long address | `address 02:00:00:00:00:00:01` | 1; `... 7 - must be 6 bytes` |
+| boundary: a device with no address | the reply has no `IFLA_ADDRESS` | the request, unchecked |
+| boundary: the get fails | the source returns `ENODEV` | the request, unchecked |
+| corner: `add` doesn't look | `link add d9 type dummy address 02:00` | no get; the request |
+| corner: no dev | `set address 02:00:00:00:00:aa` | `iplink_modify`'s no-dev refusal, as today |
+
+`TestLinkInfoDataByIndex` in `service_test.go` checks the bytes of the get (`ifi_index` set, `ifi_family` the preference, no attributes) and the address length read off the reply. The get is the tunnel prefetch's, `LinkInfoDataByIndex`, so `addrLen` is that callback.
+
+The workbench rows: the 2 `set address` rows `same`.
+
+**Mutation check:** the length compared by `>` (the long row); the get with `IFLA_EXT_MASK` (the bytes); a failed get refused rather than skipped (the `ENODEV` row); the check on `add` (the add row).
+
+#### GW2-T02 `group`
+
+**Code.** `linkArmGroup`: `duparg`, `rtnlGroupA2N` (`default` is 0; else `strtol` base 0 truncated to `int32`, refused when negative), `IFLA_GROUP` u32. With no dev it is the group-wide set: `ifi_index` 0, kind words refused, a create refused, and a bare `type` dropped, as `iplink_parse`'s early return does. `cStrtol` joins `cparse.go` for the clamp.
+
+`TestLinkWriteGroup`:
+
+| description | input | expected |
+|---|---|---|
+| positive: a number | `group 5` | `IFLA_GROUP` 5 |
+| positive: the stock name | `group default` | `IFLA_GROUP` 0 |
+| positive: hex, base 0 | `group 0x10` | 16 |
+| negative: a word | `group nosuch` | 255; `Error: argument "nosuch" is wrong: Invalid "group" value` |
+| negative: negative | `group -1` | 255; the same text |
+| negative: a second group | `group 1 group 2` | 255; `duparg`'s text |
+| boundary: the largest | `group 2147483647` | `IFLA_GROUP` 0x7fffffff |
+| boundary: one past, which wraps negative | `group 2147483648` | 255; the invarg text |
+| corner: 2^32 wraps to 0 | `group 4294967296` | `IFLA_GROUP` 0 |
+| corner: `group` is `strcmp` | `grou 5` | the dev rule, as today |
+| corner: names are `strcmp` | `group def` | 255; the invarg text |
+
+The workbench rows: the 61 `group` rows `same`, or refusing at a later GW2 keyword.
+
+**Mutation check:** `strtol` not truncated to `int` (the 2^32 row); `duparg` dropped (the second-group row); the name matched by prefix (a `group def` row, which `strtol` refuses).
+
+#### GW2-T03 GSO and GRO sizes
+
+**Code.** One `linkArmU32Max` arm, with a table entry per keyword: its `IFLA_*` type, its name for the invarg, and its bound (65535 for `gso_max_segs`, otherwise `UINT_MAX`).
+
+`TestLinkWriteGsoGro`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each of the five | `gso_max_size 32768`; `gso_max_segs 100`; `gro_max_size 524280`; `gso_ipv4_max_size 32768`; `gro_ipv4_max_size 32768` | the matching `IFLA_*` u32 |
+| positive: in word order | `gso_max_segs 1 gro_max_size 2` | the two attributes in that order |
+| negative: a word | `gso_max_size x` | 255; `Invalid "gso_max_size" value` |
+| negative: negative | `gro_max_size -1` | 255 |
+| boundary: segs at its limit | `gso_max_segs 65535`; `65536` | sent; 255 |
+| boundary: a size at `UINT_MAX` | `gso_max_size 4294967295`; `4294967296` | sent; 255 |
+| corner: no prefix match | `gso_max 5` | the dev rule |
+| corner: repeated | `gso_max_size 1 gso_max_size 2` | two attributes, no `duparg` |
+
+The workbench rows: the 49 rows `same`, or refusing later.
+
+**Mutation check:** the segs bound dropped (65536); base 10 (`0x10`); one shared attribute type (each of the five).
+
+#### GW2-T04 `addrgenmode`
+
+**Code.** `linkArmAddrGenMode`: the four names by case-insensitive compare, then the two plain nests. `pkg/xtcpnl`'s link-write encoder gets the nest if it has none.
+
+`TestLinkWriteAddrGenMode`:
+
+| description | input | expected |
+|---|---|---|
+| positive: each mode | `eui64`; `none`; `stable_secret`; `random` | `IFLA_AF_SPEC`/`AF_INET6`/`IFLA_INET6_ADDR_GEN_MODE` 0; 1; 2; 3 |
+| positive: the bytes of the nest | `addrgenmode none` | `10001a00 0c000a00 05000800 01000000` |
+| negative: an unknown mode | `addrgenmode stable` | 255; `Invalid address generation mode` |
+| boundary: case | `addrgenmode NONE` | 1 |
+| corner: the prefix | `addrgen none` | the same request |
+| corner: twice | `addrgenmode none addrgenmode random` | two `IFLA_AF_SPEC` attributes |
+
+The workbench rows: the 35 rows `same`, or refusing later.
+
+**Mutation check:** `NLA_F_NESTED` on a nest (the bytes row); case-sensitive names (`NONE`); `stable_secret` as 3.
+
+#### GW2-T05 `protodown` and `protodown_reason`
+
+**Code.** `linkArmProtodown`: goip's `parseOnOff`, `IFLA_PROTO_DOWN` u8. `linkArmProtodownReason`: `strtoul` in base 0 below 32, `on`/`off` by prefix, the nested mask and value.
+
+`TestLinkWriteProtodown`:
+
+| description | input | expected |
+|---|---|---|
+| positive: on and off | `protodown on`; `protodown off` | `IFLA_PROTO_DOWN` 1; 0 |
+| positive: a reason on | `protodown_reason 0 on` | `IFLA_PROTO_DOWN_REASON` (`NLA_F_NESTED`): mask 1, value 1 |
+| positive: a reason off | `protodown_reason 0 off` | mask 1, value 0 |
+| negative: a bad on/off | `protodown maybe` | `parse_on_off`'s error and status |
+| negative: reason 32 | `protodown_reason 32 on` | 255; `invalid protodown reason` |
+| negative: no on/off | `protodown_reason 1 up` | `on_off`'s error |
+| boundary: reason 31 | `protodown_reason 31 on` | mask and value 0x80000000 |
+| corner: `o` is `on` by prefix | `protodown_reason 2 o` | value 4 |
+
+The workbench rows: the 20 rows `same`.
+
+**Mutation check:** the reason bound at 33 (the 32 row); the value without the mask (the on row); `NLA_F_NESTED` dropped (the bytes).
+
+#### GW2-T06 `broadcast`, `carrier`, `mode` and `state`
+
+**Code.** `linkArmBroadcast` reuses `address`'s `llAddrA2N`. `linkArmCarrier` uses `parseOnOff`. `linkArmLinkMode` and `linkArmOperstate` use name tables by case-insensitive compare.
+
+`TestLinkWriteBrdCarrierModeState`:
+
+| description | input | expected |
+|---|---|---|
+| positive: broadcast | `broadcast ff:ff:ff:ff:ff:fe`; `brd ...` | `IFLA_BROADCAST` 6 bytes |
+| positive: carrier | `carrier on`; `carrier off` | `IFLA_CARRIER` 1; 0 |
+| positive: mode | `mode dormant`; `mode default` | `IFLA_LINKMODE` 1; 0 |
+| positive: state | `state dormant`; `state up` | `IFLA_OPERSTATE` 5; 6 |
+| negative: carrier | `carrier maybe` | `parse_on_off`'s error and status |
+| negative: mode and state | `mode x`; `state x` | 255; `Invalid link mode`; `Invalid operstate` |
+| boundary: case | `mode DORMANT`; `state UP` | 1; 6 |
+| corner: `b` is broadcast | `b ff:ff:ff:ff:ff:fe` | `IFLA_BROADCAST`: only `link` and `address` are matched earlier |
+
+The workbench rows: the 15 rows `same`, or refusing later.
+
+**Mutation check:** `mode` by prefix (`mod`); the operstate table off by one (`up`). `brd` by prefix is an equivalent mutant: `b` and `br` are prefixes of `broadcast`, which the chain tests first, and a longer word is a prefix of neither (V029).
+
+#### GW2-T07 `xdp off`
+
+**Code.** `linkArmXdp`: with `off` or `none` as argv's last word, the nest with fd -1 and the flags. Anything else stays `ErrNotImplemented` (a program load), recorded with its count. `xdpoffload` looks the dev up first.
+
+`TestLinkWriteXdp`:
+
+| description | input | expected |
+|---|---|---|
+| positive: xdp off | `set dev d0 xdp off` | `IFLA_XDP`: `IFLA_XDP_FD` -1, `IFLA_XDP_FLAGS` 1 |
+| positive: generic and drv | `xdpgeneric none`; `xdpdrv off` | flags 3; 5 |
+| positive: offload | `xdpoffload off` | d0's lookup; flags 9 |
+| negative: not last | `xdp off carrier on` | `ErrNotImplemented`; `ip` tries an object |
+| negative: no value | `xdp` | 255; `Command line is not complete` |
+| corner: `-force` | `ip -force link set dev d0 xdp off` | refused by goip's option parser, so goip's flags always carry `UPDATE_IF_NOEXIST`; `LinkAttrXdp`'s own table has the flags-0 row (V032) |
+
+The workbench rows: the 3 `xdp` rows and the ones behind `carrier`/`netns` `same`; `xdp-not-last` stays `refuses`.
+
+**Mutation check:** flags always sent (`LinkAttrXdp`'s flags-0 row); `UPDATE_IF_NOEXIST` dropped (`xdp off`); fd 0 (any row).
+
+#### GW2-T08 `index`, `netns`, `link-netnsid` and `parentdev`
+
+**Code.** `linkArmIndex` (`atoi`, positive, `duparg`) and `finish`'s set-without-netns refusal. `netns` was to open the namespace as `netns_get_fd` does and send the descriptor's number; at the task it stays `ErrNotImplemented` instead (see [Out of scope](#out-of-scope)), so its two rows below are a not-implemented refusal. `linkArmLinkNetnsid` uses `get_integer`. `linkArmParentdev` sends the NUL-terminated name.
+
+`TestLinkWriteIndexNetns`:
+
+| description | input | expected |
+|---|---|---|
+| positive: parentdev | `parentdev br0` | `IFLA_PARENT_DEV_NAME` `br0\0` |
+| positive: link-netnsid | `link-netnsid 5` | `IFLA_LINK_NETNSID` 5 |
+| negative: index on set | `set dev d0 index 100` | 255; `index can be used only when creating devices or when moving device to another netns.` |
+| negative: a bad index | `index 0`; `index x` | 255; `Invalid "index" value` |
+| negative: no such netns | `netns nosuch` | 255; `Invalid "netns" value` |
+| negative: link-netnsid twice | `link-netnsid 1 link-netnsid 2` | 255; `duparg` |
+| boundary: link-netnsid -1 | `link-netnsid -1` | `IFLA_LINK_NETNSID` -1 |
+| corner: netns by pid | `netns <the test's pid>` | `IFLA_NET_NS_FD` with the descriptor goip opened |
+
+The workbench rows: the 5 rows `same`, except `netns $$` rows: the shell's pid in the capture is a process that no longer exists, so those stay as recorded in the decision log.
+
+**Mutation check:** `index` allowed on set (the index row); `atoi` of `x` as valid (it is 0, refused); `parentdev` without its NUL.
+
+**Done when** (every GW2 task): as GW1-T01, with the task's rows `same` or refusing at a later GW2 keyword, and `differs` and `sends` 0. GW2-T08 closes GW2: the link rows have no `refuses` left except those the decision log lists.
+
+### GW3 — nexthop keywords
+
+Three tasks, all in `internal/goip/nexthop_write.go`'s `(*nexthopWrite).parseArg` (`ipnh_modify`'s chain in its order). Today `encap`, `dst_port` and `hw_stats` share one `ErrNotImplemented` arm.
+
+The 57 rows after GW2-T08's golden: 41 `hw_stats` (nhgrp 39, nh4 1, nh6 1), 12 `dst_port` (fibnh 10, nh4 1, nh6 1) and 4 `encap mpls` (fibnh).
+
+**What `ip` does** (`ip/ipnexthop.c` at `v7.2.0`):
+- **`hw_stats`** (`strcmp`, `:1131`): `NEXT_ARG`, then `parse_on_off`, whose error `ipnh_modify` returns. It sends `NHA_HW_STATS_ENABLE` u32, 0 or 1, where the loop reads it.
+- **`dst_port`** isn't a 7.2.0 keyword (iproute2 `ad2b2d95` adds it later). The chain's last arm, `invarg("", *argv)`, refuses it: `Error: argument "dst_port" is wrong: `, 255, with nothing sent. Any `dev` before it has been looked up by then. goip's default arm already prints that refusal.
+- **`encap`** (`strcmp`, `:1095`): `lwt_parse_encap` (`ip/iproute_lwtunnel.c:2298`) writes into a scratch buffer, which is appended raw where the loop reads it:
+  - `NEXT_ARG`, then `read_encap_type` by `strcmp` (`mpls`, `ip`, `ip6`, `ila`, `bpf`, `seg6`, `seg6local`, `rpl`, `ioam6`, `xfrm`), else `invarg("\"encap type\" value is invalid\n")`, 255.
+  - `NEXT_ARG`, then `argc <= 1` is `missarg("encap type")`: `Error: argument "encap type" is required`, 255. So the type's first argument can't be argv's last word.
+  - `NHA_ENCAP`, opened by `rta_nest`, which sets `NLA_F_NESTED`.
+  - For `mpls`, `parse_encap_mpls` (`:1610`): `get_addr` in `AF_MPLS`, which is `mpls_pton` (`lib/mpls_pton.c`). It takes up to 64 labels split on `/`, each `strtoul` in base 0 below 2^20, stored big-endian as `label << 12`, with the bottom-of-stack bit (`0x100`) on the last. `default`, `all` and `any` are refused in `AF_MPLS`. A bad address is `get_addr`'s own `Error: mpls address is expected rather than "%s".`, exit 1. More than 64 labels first prints `Error: too many labels.` It sends `MPLS_IPTUNNEL_DST`, the labels' bytes. Then an optional `ttl N` (`get_u8` in base 0, `duparg2` on a second) sends `MPLS_IPTUNNEL_TTL` u8, and the first other word ends the encap.
+  - The nest closes, and `NHA_ENCAP_TYPE` u16 (`LWTUNNEL_ENCAP_MPLS` 1) follows it.
+
+#### GW3-T01 `hw_stats`
+
+**Code.** A `hw_stats` arm: `nextArg`, link_write.go's `parseOnOff`, then `NHA_HW_STATS_ENABLE` u32.
+
+`TestNexthopWriteHwStats`:
+
+| description | input | expected |
+|---|---|---|
+| positive: on | `id 1 group 21 hw_stats on` | `NHA_ID`, `NHA_GROUP`, `NHA_HW_STATS_ENABLE` 1 |

+| corner: twice | `hw_stats on hw_stats off` | two attributes, 1 then 0 |
+
+The workbench rows: the 41 rows `same`.
+
+**Mutation check:** the value inverted (on and off); a u8 rather than a u32 (the bytes); `hw_stats` by prefix (`hw_stat`).
+
+#### GW3-T02 `dst_port`
+
+**Code.** `dst_port` leaves the not-implemented arm, so the default arm's `invarg` refuses it, as `ip` 7.2.0 does.
+
+`TestNexthopWriteDstPort`:
+
+| description | input | expected |
+|---|---|---|
+| negative: dst_port | `id 31 fdb dst_port 4790` | 255; `Error: argument "dst_port" is wrong: `, nothing sent |
+| negative: after a dev | `id 10 dev d0 dst_port 4789` | d0's lookup, then the same refusal |
+| boundary: port 0 | `id 31 via 172.16.1.2 fdb dst_port 0` | the same refusal |
+| corner: as the last word | `id 31 dst_port` | the same refusal: the word is refused before its value is read |
+
+The workbench rows: the 12 rows `same`.
+
+**Mutation check:** `dst_port` still not implemented (the rows stay `refuses`); a `NEXT_ARG` before the refusal (the last-word row).
+
+#### GW3-T03 `encap mpls`
+
+**Code.** An `encap` arm reading the type; `mpls` through a new `mplsPton` and an `xtcpnl` encoder for the `NHA_ENCAP` nest and `NHA_ENCAP_TYPE`; every other type stays `ErrNotImplemented`, since no row uses one.
+
+`TestNexthopWriteEncapMpls`:
+
+| description | input | expected |
+|---|---|---|
+| positive: one label | `id 51 encap mpls 101 via 172.16.1.2 dev veth1` | `NHA_ID`, `NHA_ENCAP`\|`NLA_F_NESTED`{`MPLS_IPTUNNEL_DST` `00065100`}, `NHA_ENCAP_TYPE` 1, `NHA_GATEWAY`, `NHA_OIF` |

+| boundary: 64 labels and 65 | 64 `/`-joined labels; 65 | 256 bytes; `too many labels` and the address error |

+| corner: hex, base 0 | `encap mpls 0x10 via 172.16.1.2` | `00010100` |
+| corner: another type | `encap ip id 1 dst 10.0.0.1 via 172.16.1.2` | `ErrNotImplemented` |
+
+The workbench rows: the 4 rows `same` (2 accepted, and 2 with `fdb` that the kernel refuses).
+
+**Mutation check:** `NLA_F_NESTED` dropped (the bytes); the bottom bit on every label (the stack); `NHA_ENCAP_TYPE` before the nest; the `missarg` check dropped (the label-last row).
+
+**Done when** (every GW3 task): as GW1-T01, with the task's rows `same`, and `differs` and `sends` 0. GW3-T03 closes GW3 and expands GW4.
+
+### GW4 — rule `realms`
+
+One task, in `internal/goip/rule_write.go`'s `(*ruleWrite).parseArg` (`iprule_modify`'s chain in its order). Today `realms` is `ErrNotImplemented`, on the grounds that `ip` reads realm names from `rt_realms`; GW1-T03's `getRtRealmsOrRaw` now takes the numbers and the stock file's one name, `cosmos`.
+
+The 30 rows after GW3-T03's golden are all rule4, and all carry `realms 10`.
+
+**What `ip` does** (`ip/iprule.c` at `v7.2.0`):
+- **`realms`** (`matches`, `:1050`): `NEXT_ARG`, then `get_rt_realms_or_raw` (`ip/rtm_map.c:118`), the parse `ip route`'s `realms` uses: `[FROM/]TO`, each half a name or 0 to 255, `FROM` in the high 16 bits; else `get_unsigned` in base 0 over the whole argument. A failure is `invarg("invalid realms\n")`, 255. It sends `FRA_FLOW` u32 where the loop reads it, with no `duparg`.
+- Only `not`, `from`, `to`, the preference group, `tos`/`dsfield` and `fwmark` come before it, and none of their `matches()` patterns starts with `r`, so `r` is `realms`.
+
+#### GW4-T01 `realms`
+
+**Code.** A `realms` arm: `nextArg`, `getRtRealmsOrRaw`, then `FRA_FLOW` u32.
+
+`TestRuleWriteRealms`:
+
+| description | input | expected |
+|---|---|---|
+| positive: a TO realm | `realms 10` | `FRA_FLOW` 10 |
+| positive: FROM/TO | `realms 1/2` | `FRA_FLOW` 0x00010002 |
+| positive: the stock name | `realms cosmos` | `FRA_FLOW` 0 |
+| positive: raw past a half | `realms 0x10000` | `FRA_FLOW` 65536 |
+| negative: a word | `realms x` | 255; `invalid realms` |
+| negative: no value | `realms` | 255; `Command line is not complete` |
+| boundary: both halves at 255 | `realms 255/255` | 0x00ff00ff |
+| boundary: raw at UINT_MAX | `realms 4294967295` | 0xffffffff |
+| corner: `r` is realms | `r 10` | `FRA_FLOW` 10 |
+| corner: twice | `realms 1 realms 2` | two `FRA_FLOW`, no `duparg` |
+
+The workbench rows: the 30 rows `same`.
+
+**Mutation check:** the halves swapped (`1/2`); `FRA_FLOW` as another type (the bytes); `realms` by `strcmp` (`r`).
+
+**Done when:** as GW1-T01, with the 30 rows `same`, and `differs` and `sends` 0. GW4-T01 closes GW4 and expands GW5.
+
+### GW5 — matrix rows and the VM gate
+
+Four tasks. GW5-T01 to T03 add goip-parity write rows in `internal/goipparity/commands.go` for the keywords GW1 to GW4 built, by object, with an offline table each. GW5-T04 runs the VM, gates the rows and closes the plan.
+
+The O5 golden already compares all 579 moved rows offline against their captures, so the matrix doesn't take all 555 that sent a request. It takes a sample that runs both `ip` and goip live in the parity VM:
+- **Which rows.** For each keyword form a task built, the first workbench row by id that is `same` now, once with `ip` rc 0 and once with rc 2 if the corpus has one. A "form" is a distinct encoding: each `pref` name, `hw_stats on` and `off`, a one-label and a two-label `encap mpls`, and so on, as each task's section lists them.
+- **Setup.** The row's `pre`, split on ` && ` into `ip` subcommands. A row whose `pre` needs anything else (a `sysctl`, a module) is passed over for the next row of its form, and a form with no such row is recorded in the task's ledger row rather than given a new setup.
+- **Floor.** The row's `ip.pcap` record count: lookups, the write and its answer.
+- **Rows `ip` refused before sending** (rc 1 or 255) aren't matrix rows, since a write row needs goip to exit 0. The offline tables hold them.
+- **Repeats.** A row whose `cmd` a picked row already has is passed over for the next row of its form, since `Name` is the allowlist key.
+- **Names.** `Slug` is `gw_` and the id with its `/` and `-` as `_` (`route4/pw-023` is `gw_route4_pw_023`), since a slug takes `[a-z0-9_]` only. Argv is the row's `cmd` without the leading `ip`.
+- **Gating.** The rows are ungated until GW5-T04; `TestUngatedSurfaceIsNotVacuous` excepts the `gw_` slugs until then.
+
+#### GW5-T01 the route rows
+
+**Rows.** After the route write rows: `nhid` (a unicast by id, blackhole by id, IPv6), `pref` (`low`, `medium`, `high`, a number), `expires`, `tos` and `dsfield`, `realms` (`TO` and `FROM/TO`), `vrf` (a table under 256 and one over), and multipath `nexthop` (two hops, weights 1 and 256, `onlink`, `via inet6` on an IPv4 route, a per-hop `realms`).
+
+`TestGwRouteMatrixRows` (`internal/goipparity/commands_gw_test.go`):
+
+| description | input | expected |
+|---|---|---|
+| positive: one row per form and rc | the route forms | the first `same` row by id for each, rc 0 and rc 2 |
+| negative: no `ip`-refused row | the route rows with rc 1 or 255 | absent |
+| boundary: each floor | `Floor` | the row's `ip.pcap` record count |
+| corner: each setup | `Setup` | the row's `pre`, split on ` && `, without `ip` |
+| corner: a passed-over row | a form whose first row needs a `sysctl` | the next row of the form, or the form recorded as having none |
+| corner: each name is unique | the rows' `Name`s and `Slug`s | no two alike |
+
+`TestGwSetup`, the setup rule on its own:
+
+| description | input | expected |
+|---|---|---|
+| positive: ip steps split and trimmed | `ip link add d0 type dummy && ip link set d0 up` | the two steps without `ip` |
+| positive: two pre entries in order | two `ip` entries | both, in order |
+| negative: a sysctl step | an `ip` step `&&` a `sysctl` | not usable |
+| negative: a step tolerating a failure | `["ip …", [2]]` | not usable |
+| boundary: no pre | `[]` | usable, no steps |
+| corner: ip as a word's prefix | `ipset create …` | not usable |
+
+**Mutation check:** a floor one short (the floor row); a setup step dropped (the setup row); an rc 255 row added (the negative row); the repeat pass-over dropped (a `dup-2` form); a non-`ip` step skipped (`TestGwSetup`).
+
+#### GW5-T02 the link rows
+
+**Rows.** After the link write rows: the `set address` length lookup, `group` (with a dev, and the group-wide set), the five GSO and GRO sizes, `addrgenmode` (each mode), `protodown` and `protodown_reason`, `broadcast`, `carrier`, `mode`, `state`, `xdp off` (each of the four keywords), `index` on a create, `link-netnsid` and `parentdev`.
+
+`TestGwLinkMatrixRows`: GW5-T01's table over the link forms, plus:
+
+| description | input | expected |
+|---|---|---|
+| corner: a set's floor counts the address-length get | a `set … address` row | the lookup, the get by index, the write and its answer |
+| boundary: the group-wide set | `^ip link set group` | no row: the corpus never runs one, so its no-lookup floor of 2 is left to the offline tables |
+
+**Mutation check:** as GW5-T01, and the address-length get left out of a floor.
+
+#### GW5-T03 the nexthop and rule rows
+
+**Rows.** After the nexthop and rule write rows: `hw_stats on` and `off` (a single nexthop and a group), `encap mpls` (one label, two, a `ttl`, an IPv6 gateway), and rule `realms` (`TO` and `FROM/TO`).
+
+`TestGwNexthopRuleMatrixRows`: GW5-T01's table over these forms. `dst_port` has no row, since `ip` 7.2.0 refuses it. `encap mpls` has none either: its four corpus rows run `sysctl`, so they are passed over and recorded.
+
+**Mutation check:** as GW5-T01.
+
+#### GW5-T04 the VM gate
+
+| description (VM) | input | expected |
+|---|---|---|
+| positive: two consecutive clean runs of each section | `goip-parity -- --section route,link,nexthop,rule`, then the full run, which runs the four sections again | the GW5 rows `PASS` on both runs, and every gated row of the sections still `PASS` |
+| corner: the kernel-refused rows compare on the request | the rc 2 rows | `PASS` |
+| positive: one clean full run | `goip-parity` with no section | every gated row `PASS` |
+
+Then the rows go in `gated_commands`, each in `TestAllowlistCommitted`'s earned list. The full run is the second run of each section and also the full run the next push needs.
+
+**Done when:** the offline tables pass; the section runs and the full run are clean; the rows are gated; lint-baseline passes. It closes GW5 and the plan.

 loosened back silently. No exclusion was added and `pkg/misc/misc_test.go`'s
 `//nolint:gosec` was left alone — it is a different argument, and a real one.
 
+(Since then, commit 78ae084b replaced that `//nolint:gosec` and 69 others with
+checked conversions. See the TODO below.)
+
+### TODO: G115, the narrowing conversions the exclusion hides
+
+**Status: open, 2026-11-02. To be taken on soon.**
+
+`.golangci.yml` and `nix/checks/go-sec.nix` exclude G115 repo-wide, with the
+reason "all are bounds-checked". That isn't true. With G115 switched back on,
+gosec reports **474** narrowing conversions, 233 of them in tests. None of the
+lint checks can see them while the exclusion stands.
+
+Commit 78ae084b fixed the 65 sites that carried a `//nolint:gosec` (539 down to
+474). Its helpers in `pkg/cint` are the pattern to reuse: a mask (`Bits`,
+`Low32`, `LongBits`), or a two-sided guard that reports a value that doesn't
+fit (`U8`/`U16`/`U32`, `U*From64`, `Int64`). gosec accepts only those two
+shapes as proof that a conversion can't overflow.
+
+By package (findings / of which in tests), measured on 78ae084b's parent plus
+its diff:
+
+| package | findings | in tests |
+|---|---|---|
+| `pkg/xtcpnl` | 123 | 83 |
+| `internal/goip` | 102 | 34 |
+| `pkg/linkmonitor` (incl. `internal/*`) | 70 | 40 |
+| `internal/goip/render` | 28 | 0 |
+| `pkg/xtcp` | 25 | 17 |
+| `cmd/xtcp2` | 23 | 1 |
+| `pkg/nlparity` | 16 | 16 |
+| `pkg/io_uring` | 12 | 4 |
+| `pkg/nsdiscover` | 10 | 8 |
+| `pkg/lldp`, `tools/nlcapgen` | 8 each | 3, 5 |
+| `pkg/localnet` | 6 | 4 |
+| `gen/go/xtcp_flat_record` (generated) | 5 | 5 |
+| the remaining 17 packages | 1–4 each, 38 in all | 13 |
+
+Plan: fix package by package, starting with `pkg/xtcpnl`, `internal/goip`
+and `internal/gordma` (about 260 sites). A narrowing that can lose data
+becomes an error, as `ErrBondSettingRange` did for bond values, rather than
+silent truncation. When the count reaches zero, delete G115 from both
+exclusion lists so it can't come back.
+
+To measure it, the exclusion has to be off:
+
+```sh
+# in a scratch worktree (the checked-in vendor/ may be stale)
+go mod vendor
+sed '/- G115/d' .golangci.yml > /tmp/golangci-g115.yml
+golangci-lint run -c /tmp/golangci-g115.yml --enable-only gosec \
+  --max-issues-per-linter 0 --max-same-issues 0 ./... | grep -c G115
+```
+
+G304 (file path from a variable) is in the same position, at 213 findings.
+Its exclusion reason is narrower and true for the sites it names, but it
+covers the whole repo.
+

+//   - check_duparg keys each word on its attribute: group and remote share
+//     IFLA_VXLAN_GROUP, and a flag and its `no` form share theirs. A second
+//     one is duparg2 (255), whose key is the keyword ip names, the flag
+//     itself, or reserved_bits' value.
+//   - group and remote refuse each other before NEXT_ARG.
+//   - The addresses go through get_addr with the other address's family,
+//     whose failure is exit(1).
+//   - dev resolves as it is read, and a name that doesn't resolve is
+//     exit(nodev), 255.

+# brmpls-write-corpus.exp - the bridge FDB, bridge VLAN and MPLS captures
+# BIRD's netlink parser needs (docs/netlink/coverage-status.md, "Captures an
+# outside consumer needs: BIRD's netlink parser", B1)
+#
+# Sourced AFTER vm-lib.exp, netlink-topology.exp, addr-topology.exp,
+# addr-corpus.exp and rtnl-write-corpus.exp, by scripts/capture-link-writes.exp,
+# which loads MODULES and then runs each row into link-write/brmpls/<slug>/,
+# last of all, so no earlier fixture moves. Data plus small procs, kept out of
+# the driver so the hermetic check (scripts/brmpls-write-corpus-test.exp) can
+# read it without a console, as rtnl-write-corpus.exp is.
+#
+# A ROW IS {slug floor pre command readbacks rc}, as in rtnl-write-corpus.exp,
+# whose readback_args the driver uses for these rows too.
+#
+#   floor      2 for the write and its NLMSG_ERROR, or a dump and its
+#              NLMSG_DONE; 2 more when the command names a device (`ip` and
+#              `bridge` resolve it with an RTM_GETLINK of their own first).
+#              The event rows' floors count the canary's and the trigger's
+#              requests and answers, without the notifications, which are
+#              what the rows are for and which the until-EREs prove
+#   pre        steps run in the row's fresh namespace before the capture
+#              window opens; see pre_step
+#   rc         0 for an accepted write; 2 for one the kernel refused through
+#              `ip` (rtnl_talk's error, negated by do_cmd); 255 for one it
+#              refused through `bridge`, whose do_cmd returns the -1
+#              unnegated (bridge/bridge.c)
+#
+# WHY THE MODULES LOAD LAST
+#
+# mpls_router gives every Ethernet and loopback device an mpls_dev, and with
+# it an AF_MPLS netconf entry and RTM_GETSTATS afstats, so loading it before
+# any other row would change those rows' readbacks. bridge is already loaded
+# (the reads corpus builds br0); mpls_iptunnel is the encap mpls lwtunnel.

+# kind-write-corpus-test.exp - table-driven test for kind-write-corpus.exp,
+# with no microVM and no console
+#
+# Usage: kind-write-corpus-test.exp
+#
+# Run by nix/checks/vm-lib-exp.nix after xfrm-write-corpus-test.exp, the
+# same way: the corpus is data, and its procs (readbacks, row,
+# readback_args, rc_problem) need no shell.
+#
+# The slugs, statuses and option keywords are written out again below as
+# literals rather than read from the corpus, so a row dropped or changed
+# there has to disagree with something that was not edited with it.
+#
+# What this does NOT cover: what the guest runs or what the kernel answers.
+# The KP phases' parser tests pin that in the committed fixtures.
+#
+# Every row has a name, a description that starts with its class
+# (positive/negative/boundary/corner) and an expected value.

+"""xtcp2-nlcap-batch: run a rows file of netlink capture rows in the guest.
+
+The guest half of the nl_mon capture workbench
+(docs/netlink/coverage-status.md, "Workbench and generated rows"). The
+host CLI, xtcp2-nlcap-ws, copies a rows file in and runs this by store path
+over one ssh call; it pulls OUTDIR back.
+
+A rows file is JSON Lines, one row per line:
+
+    {"id": "tc/fq-0001", "desc": "positive: ...", "cmd": "tc qdisc ...",
+     "pre": ["ip link add d0 type dummy", ["ip link del x", 1]],
+     "readback": [{"name": "qdisc", "cmd": "tc -j qdisc show dev d0"}],
+     "proto": "route", "floor": 0, "modules": ["sch_fq"], "serial": false,
+     "expect": {"rc": 0}}
+
+Each row runs in a fresh network namespace with its own nlmon0, through the
+same `xtcp2-nlcap` primitives the corpus drivers use: ns-add, write (the
+command, inside the capture window) and capio (each readback). nlmon is per
+network namespace, so rows in different namespaces cannot see each other's
+messages, and `-j N` runs N of them at once. A row marked serial runs with no
+other row active: a sysctl outside the namespace, or a module load, is
+kernel-wide.
+
+Every module any row names is loaded once, before the first row, so every
+row of a batch sees one kernel state. A module loaded half way through would
+give the rows either side of it different fallback devices and ifindexes.
+
+Each row's directory gets cmd.json: the row as given, the kernel and
+iproute2 versions, and the result. That is the record a table test reads.
+Nothing in it depends on the clock, so a replay on a fresh boot diffs clean.
+
+Exit status: 0 when every row ran (whatever its rc), 1 when a row could not
+be captured or its rc differed from expect.rc, 2 on a bad rows file or
+usage.

+Usage: ... pedit munge [ex] <MUNGE> [CONTROL]
+Where: MUNGE := <RAW>|<LAYERED>
+	<RAW>:= <OFFSETC>[ATC]<CMD>
+ 		OFFSETC:= offset <offval> <u8|u16|u32>
+		ATC:= at <atval> offmask <maskval> shift <shiftval>
+		NOTE: offval is byte offset, must be multiple of 4
+		NOTE: maskval is a 32 bit hex number
+ 		NOTE: shiftval is a shift value
+		CMD:= clear | invert | set <setval> | add <addval> | decrement | retain
+	<LAYERED>:= ip <ipdata> | ip6 <ip6data>
+ 		| udp <udpdata> | tcp <tcpdata> | icmp <icmpdata>
+	CONTROL:= reclassify | pipe | drop | continue | pass |
+	          goto chain <CHAIN_INDEX>
+	NOTE: if 'ex' is set, extended functionality will be supported (kernel >= 4.11)
+For Example usage look at the examples directory

+// value type and encoder, and has its own table and decoder.
+//
+// The table is in bridge_slave_print_opt's order (ip/iplink_bridge_slave.c
+// at v7.2.0). Its quirks:
+//   - Four keywords name an attribute by another name: hairpin is
+//     IFLA_BRPORT_MODE, root_block IFLA_BRPORT_PROTECT, flood
+//     IFLA_BRPORT_UNICAST_FLOOD, and mcast_fast_leave is IFLA_BRPORT_FAST_LEAVE
+//     again, which fastleave already sets. print_opt prints the attribute
+//     under both words, the second in text only.
+//   - nobackup_port is backup_port with ifindex 0; it has no row, as the
+//     argv parser turns it into a backup_port setting of 0.
+//   - The kernel sends six attributes 7.2.0 does not print: the two MRP
+//     flags and the EHT host and multicast group counters. They are
+//     read-only rows with no keyword, so the decoder keeps them and a
+//     renderer skips them.

+//   - O6: every tc message in every capture (command and readbacks) parses,

+//   - O3: a qdisc, class or filter request carries what its command line

+//     argument loops do (tc/tc_qdisc.c tc_qdisc_modify, tc/tc_class.c
+//     tc_class_modify, tc/tc_filter.c tc_filter_modify), so a request that

+// running a shell:
+//
+//   - each test function, after the functions the script's main loop runs
+//     before it, is one group; calls to the script's own functions are
+//     inlined with their arguments, and their locals are scoped;
+//   - a `for` loop over a literal list, or over `$(seq A B)`, runs its body
+//     once per word; one over a computed list is skipped;
+//   - lines under if, case, while or until are skipped, since which branch
+//     runs is not known statically;
+//   - `ip -netns <the test's namespace>` loses the option, the row running
+//     in its own namespace; a command in another namespace is skipped, and
+//     a device the selftest moves to another namespace stays here,
+//     unaddressed;
+//   - `log_test $? N "msg"` right after a command says the command's rc
+//     is N, and N's sign gives the row its positive: or negative: class;
+//   - a command needing anything else (command substitution, a pipe, an
+//     unresolved variable) is skipped, with the reason.

+// The ss space (W5c): `ss` over the inet socket tables, which it reads with
+// SOCK_DIAG_BY_FAMILY on NETLINK_SOCK_DIAG. iproute2's side is misc/ss.c:
+// inet_show_netlink sends one dump per address family (AF_INET, then
+// AF_INET6, unless -4 or -6 picks one) and sockdiag_send builds each
+// request: struct inet_diag_req_v2 with the protocol, the state mask and
+// the extension bits, then the filter compiled to bytecode by
+// ssfilter_bytecompile (INET_DIAG_REQ_BYTECODE), then the protocol again in
+// INET_DIAG_REQ_PROTOCOL when it is over 255 (MPTCP). The kernel's side is
+// net/ipv4/inet_diag.c: inet_diag_bc_audit refuses bad bytecode and
+// inet_diag_bc_run applies it to each socket.
+//
+// Every row's namespace holds the same sockets (ssHolder), so the corpus
+// test (pkg/xtcpnl/xtcpnl_ws_ss_test.go) knows which sockets each reply
+// should list. A value's facts say what the request must carry: protocol,
+// families, states (the mask the kernel reads), ext, and pred, the filter
+// as the user meant it, in a prefix notation the test evaluates on its own
+// (and(a,b), or(a,b), not(a), and atoms such as sport>=1024,
+// src=127.0.0.0/8:22, auto, mark=16/255, dev=lo, cgroup=PATH). bc=none marks a
+// filter ss applies itself and sends no bytecode for; bug names an
+// iproute2 bug the row shows, which the test asserts is still there.
+
+// ssHolder opens the sockets every ss row lists, then forks a child that
+// holds them for 10 s with its stdio on /dev/null, so the pre step returns
+// at once. With the namespace's port range one port wide, both autobound
+// connects take port 45000. pkg/xtcpnl/xtcpnl_ws_ss_test.go wsSsKnown is
