gen5: the hello map, the real clock opcodes, and record fields the captures actually support - #31
Conversation
📝 WalkthroughWalkthroughThe PR expands the public Gen5 API, adds Labrador and revised clock commands, decodes new control-plane events, corrects v18–v26 historical fields, and adds version-22 research telemetry decoding with reconstruction and validation tests. ChangesGen5 protocol expansion
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to The PR adds the gen5 clock-write path and changes a public record API; downstream command filters may reject clock updates, and existing callers may break if the removed getter is not accounted for. It is mergeable with explicit owner awareness or follow-up for these bounded integration and compatibility risks. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

In `@lib/src/control.dart`:
- Around line 860-867: Add a decode test in the existing control-plane offsets
test suite for Cmd.getCustomAdvertisingName (0x8D) using a gen5 profile and a
reply body containing a sample advertising name; assert the decoded
advertising-name field matches the sample and, optionally, the existing
Cmd.getAdvertisingNameHarvard (0x4C) decoding for the same body. Use the actual
decoded key written by _decodeAdvName.
- Around line 1267-1277: In the event map construction within the relevant
decoder, move the ...e.decoded spread before the frame-level keys so event,
event_id, ts_epoch, and retain_raw remain authoritative. Leave the console_log
map unchanged.
In `@lib/src/gen5_records.dart`:
- Around line 1194-1213: Make the public lists immutable in both affected sites:
at lib/src/gen5_records.dart lines 1194-1213, pass List<int>.unmodifiable
wrappers for samples and outOfRangeSampleIndices to Gen5PpgReconstruction; at
lines 1478-1509, pass a List<int>.unmodifiable wrapper for deltas as
opticalDeltas to match Gen5ResearchOpticalWindow.
- Around line 488-494: Record the breaking removal of trustedHeartRateAlt in
release metadata by adding a changelog entry and incrementing the package
version from 1.0.0 in pubspec.yaml, clearly identifying the API removal as
breaking.
In `@test/control_plane_offsets_test.dart`:
- Around line 185-263: Add a test in the existing control-plane response test
group that constructs a revision-4 GET_ALARM_TIME reply and verifies
alarm_active is true only for flag value 1, and false for 0 and another non-1
value. Use the existing response-building and endian helper symbols, and also
assert the existing alarm_epoch decoding to confirm the complete revision-4
payload remains correct.
In `@test/doc_conformance_test.dart`:
- Around line 47-66: Update the body length assertion in the SET_ALARM_TIME gen5
conformance test to require exactly 21 bytes instead of accepting any length of
at least 21, while preserving the existing byte-content checks and test setup.
In `@test/gen5_command_surface_test.dart`:
- Around line 118-132: Remove the standalone v8 dormant-flag test and retain the
later test that checks both kGen5R22EnableFlags and
kGen5R22PreviouslyWrittenFlags for enable_r22_v8_packets; leave the v4 test
unchanged.
In `@test/gen5_v22_test.dart`:
- Around line 452-470: Add a synthetic tag-4 test alongside the existing
historical decoder cases, using the shared tag-1/2 layout with one window and
metadata at base 117. Assert the parsed window, acceleration, channel state,
flags snapshot, 11-byte extendedMetricsRaw, null pipRecordUnix, and empty
accelRawX via parseGen5Historical.
- Around line 22-29: Extract the duplicated hex helper into a shared test
utility, choosing one consistent whitespace-normalization behavior, then remove
the local definitions from gen5_v22_test.dart, gen5_record_fields_test.dart, and
gen5_historical_test.dart and import the shared helper in each file.

Record the breaking API removal in release metadata. No executable or TypeScript mirror references remain, but explanatory references remain in lib/src/gen5_records.dart and test/gen5_historical_test.dart. No changelog exists, and pubspec.yaml remains at 1.0.0; add a changelog entry and bump the package version for this breaking removal.

Extract the shared hex helper.
hex is now defined in at least three test files (test/gen5_v22_test.dart, test/gen5_record_fields_test.dart, test/gen5_historical_test.dart), with a small difference: this copy strips all whitespace, the other copies strip only spaces. Move one implementation into a shared test helper file and import it. This removes the divergence and the duplication.

this is real work — i checked the v26 relayout against my own captures and it holds up hard. but three things have to change before it can go in. 1. the comments and test names that say how this was worked out. there's a lot of it, plus a real band serial hardcoded in 2. that claim is the whole basis for deleting 3. smaller, all fixable:
the v22 decoder i'm undecided on. ~1,150 lines and i have zero v22 records to check any of it against — both my captures already had the r22 enable run and still show none. it's internally consistent and unknown tags fall through to raw, so it can't fabricate. but that's a big surface to adopt on one person's captures. can you share the v22 fixtures? things i confirmed on real data, so you know what's solid: the 20-bit i32 at |

All three blockers are in, plus most of the smaller list. The branch was rebuilt on top of #30 as two clean commits with the provenance scrubbed out of comments, test names, fixtures and the PR body — serial replaced, fixture timestamps synthesized (the tag-5 carrier/embedded 39 s offset is preserved as a wire fact), citations rewritten to state the fact only. inner[29] — you're right, and I re-ran it on the full corpus (1,586,730 v18 records, two bands): exact +32767 — confirmed as a rail and handled in Smaller items: history-fail split (gen5 146/147 — one observation that may resolve your note: 0x93 IS decimal 147, so your record of "0x93 as a clock opcode" and this deprecation are about the same number. Both can be true — my probe only establishes that 10/11 answer; it doesn't prove 147 dead. If you have a capture with 0x93 in flight I'll gladly un-deprecate; until then "deprecated, not removed" seems like the right posture. Happy to settle this before the edge repin, per your note. v22 fixtures — the five 176-byte bodies now live in the test file with their timestamps synthesized, so the layouts are checkable byte-by-byte from the repo itself. If you want more than that to form a view on the decoder, say what shape helps and I'll see what I can do. |
