From a82622bba67df8f09db4c780a77ab9d5c5355842 Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Wed, 9 Sep 2026 07:37:13 +0100 Subject: [PATCH 01/45] chore: carry three issue captures off main onto a branch These three records were captured in an earlier session and were left untracked on main, where nothing substantive is meant to land. They are committed here unchanged, on the branch, so they stop riding the working tree of whatever session touches this checkout next. Not this branch's subject: they concern the launch flow for a managed repo, a session URL that reached three commit messages and two pull requests, and the AI-assistance disclosure convention covering commits only.

From a8e1695b96d47b3199fa087f646a6499d0c59333 Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Wed, 9 Sep 2026 07:37:25 +0100 Subject: [PATCH 02/45] chore: record the sub-agent transcript capture gap and its design The transcript store captures only the top-level session transcript. Every sub-agent transcript is missed, which on the measured corpus is roughly three quarters of all recorded bytes: 968 sub-agent files against 68 session files. The session-end hook reads the single transcript path the harness hands it and enumerates nothing, and no sub-agent event is registered. Records the finding, the intent that closes it, its spec, and the lineage decision the spec turns on. The intent covers three capabilities the product thinker specified together: capture sub-agent transcripts going forward, ingest the history already on disk per repository under that repository's own redaction configuration, and reconstruct any session as one agent-readable artefact with a telemetry file describing what the work cost. The ADR settles how lineage is carried. Explicit record fields, not the composite session id that 176 of the store's 267 records now carry, which cannot be reached from the identifier of the session that produced it and never recorded the agent type at all. Also captures a contradiction found while writing the spec: AGENTS.md says an ADR ordinal is hand-numbered and needs coordination between checkouts, while the decide verb mints a collision-proof timestamp id. The stale surface is the one an agent reads first, and it caused this ADR to be deferred on a risk that adr-45 had already removed.

A sub-agent's transcript belongs to +the session that spawned it, and at greater depth to another sub-agent, so the +record has to answer two questions the schema cannot express: which session does +this belong to, and what kind of agent produced it. + +The constraint was already locked by use rather than by design. Operators +capturing sub-agent transcripts by hand had only one writable identifier, so +they encoded the parent into it as `--agent-`. That +convention is in the store now: 176 of 267 records carry it. `Read` matches the +session id by exact string, so none of those records can be reached from the +identifier of the session that produced them, the parent prefix is truncated to +whatever the operator pasted, and the agent type was never recorded at all. + +The harness supplies what is missing. Its sub-agent completion event carries the +spawning session id, the agent id and the agent type as distinct values; the +per-agent sidecar adds spawn depth and the parent agent. The information exists +at capture time and is being discarded. + +## Decision + +We will carry sub-agent lineage in explicit record fields, and the session id +will mean one thing only: the session a transcript belongs to. + +A record gains fields naming the agent, its parent agent, its type, its spawn +depth, the tool use that spawned it, and where that lineage came from. A +sub-agent record's session id is the full, untruncated id of the spawning +session, which is also what a parent record carries, so a reader holding a +session id reaches the whole session by matching one field. Records already +written under the composite convention are migrated onto the fields, recovering +the untruncated parent from the transcript body the record already stores. + +The new fields are externally supplied text and pass through the same redaction +gate as the transcript body. There is no field on this record that the scanner +does not see. + +## Alternatives Considered + +- **Continue the composite session id.** Costs nothing to adopt, since it is + already in use, and needs no migration. Rejected: it is the status quo whose + failure prompted this. It makes the identifier mean two things, keeps every + existing sub-agent record unreachable from its session, and cannot carry the + agent type at all. The convention would also harden with each capture, since + every reader would have to learn to parse it. +- **Explicit fields on the record (chosen).** Each value means one thing, the + session id keeps its existing meaning, and a reader filters rather than parses. + Costs a schema version, a migration of 176 records, and the widening of the + idempotency key so that two sub-agents of one session are not mistaken for + duplicates. Chosen because the store exists to be read back, and an identifier + that must be parsed to be understood is not readable. +- **A separate sidecar index mapping agents to sessions.** Leaves the record + untouched and keeps the migration out of the store. Rejected: it puts lineage + somewhere the record is not, so a record copied, exported or reconstructed + without its index loses its meaning, and it introduces a second source of truth + that can drift from the records it describes. +- **A separate record family for sub-agent transcripts.** Clean separation, no + schema change to the existing family. Rejected: a sub-agent transcript is the + same artefact captured through a different door, and splitting the family would + duplicate the redaction path, the idempotency rule and every reader. + +## Consequences + +Easier: a session can be reconstructed by matching one field, an audit can ask +what a session's reviewers concluded, and the corpus can be grouped by agent type +without parsing identifiers. The reconstruction and telemetry work in +itd-2609090559376002 depends on exactly this and needs no further schema change. + +Harder: the record carries a schema version and readers must admit both shapes, +since records written before this decision keep theirs until migrated. The +migration is a write over existing records and is therefore report-by-default, +applying only when asked. + +New obligations: the idempotency key must include the agent id, or two sub-agents +of one session that produced byte-identical transcripts would collapse into one +record. Migration must not rewrite the content hash or the filename, both of +which existing readers and the deduplication path depend on.

What survives of a delegated task is the prompt that launched it and the summary it returned, while every command it ran, every file it edited and every judgement it made is dropped. Delegated work is the bulk of the work, better than three quarters of the recorded volume, so the store has been keeping the smaller half. This intent collects the missing half, backfills the history that already exists, and makes any session reconstructable as one artefact that another agent can be given as context. +> +> "I delegate the reviews, the sweeps and most of the implementation to sub-agents, so that is where the reasoning I would want to audit actually lives," said Maya, an autonomous-development practitioner. "When I went back to reconstruct why a change was made, the store had the two lines where I handed the task off and the summary that came back, and nothing in between. The part I most needed to read was the part that was never kept." + +## Why This Matters + +abcd's transcript corpus exists so that work can be reconstructed after the fact. That promise is answered for the main thread and silently unanswered for everything delegated out of it: + +- **The session transcript IS captured:** the session-end hook receives the path to it and stages it for redaction and storage. +- **Sub-agent transcripts are NOT:** they are written per sub-agent, and no hook abcd registers ever names them, so nothing enumerates or reads them. + +The asymmetry is not marginal. On the measured corpus, sub-agent transcripts held roughly three quarters of all recorded bytes, outweighing session transcripts by more than three to one. What the parent retains for each delegated task is the launch prompt and the returned report: in one measured case, two lines standing in for several hundred, discarding every tool call the agent made along the way. + +This is a symmetry failure rather than a missing feature. The corpus already exists, already redacts on write, and already works for one caller class. The sub-agent caller was simply never routed into it. The harness offers a completion event for sub-agents whose payload names the finished sub-agent's own transcript, so the gap can be closed by feeding the existing store, with no new capture mechanism and no dependence on the harness's undocumented on-disk layout. + +Two consequences make this urgent rather than tidy. Uncaptured transcripts age out under the harness's retention sweep, so the loss is permanent and ongoing. And the workaround already in use, inventing a composite identifier by hand, produces records that cannot be found from the identifier a reader actually holds. + +Capturing the material is only half of the value. A session's transcripts are of interest as a set rather than one at a time, both for reading back what happened and as a corpus for studying how humans and agents actually work together. Every measure that study needs is already present in the raw transcripts and is discarded along with them. + +## Typed Links + +- **refines `itd-59`** (autonomous-worker transcript capture): the adjacent half of the same corpus. itd-59 covers the worker on abcd's own run seam; this covers sub-agents spawned inside an interactive session. +- **refines `adr-29`** (native transcript corpus): feeds the store that ADR established rather than redesigning it. +- **corrects a premise in `itd-59`**, flagged for human confirmation and not auto-classified: itd-59's "What's Out of Scope" records interactive-session capture as already solved. That holds only of the main thread, and planning itd-59 on the unqualified claim would rebuild the same blind spot. + +## What's In Scope + +- **The capture gap:** every sub-agent transcript lands in the corpus under the repository it belongs to, with the same redaction and the same fail-closed refusal on a degraded scanner as a session transcript. +- **All sub-agent completions** at any nesting depth, including sub-agents spawned by other sub-agents. +- **Provenance enough to read the result back:** a stored sub-agent transcript can be traced to the session that spawned it and to the kind of agent it was. +- **Ingest of history that already exists:** transcripts still on disk but never captured can be brought into the corpus for the repository they belong to, under that repository's own redaction configuration and never another's. +- **Reconstruction as an artefact:** any session can be emitted as one self-contained, agent-readable file containing the main thread and every sub-agent it spawned, suitable for handing to a model as context. +- **A telemetry file beside each reconstruction**, describing token usage, wall-clock duration, turn and tool-call counts, models used and agent types, so the corpus can be studied rather than only read. +- **Feed, don't fork:** capture and ingest reuse the existing staging and redaction path rather than adding a second mechanism beside it. + +## What's Out of Scope + +- **Redesigning the corpus.** The store's per-repo keying and its single-owner provisioning stay as they are. +- **The harness's own retention policy.** How long the harness keeps its transcripts is configuration outside abcd's control. +- **Structured extraction of findings.** Turning a review agent's transcript into structured findings is a separate concern from keeping the transcript. +- **Adopting orphaned transcripts by default.** Where a transcript's repository no longer exists, the default is to ignore it; adopting it is opt-in per repository, described below. + +## Mechanism + +We expect routing sub-agent capture through the harness's sub-agent completion event to close the gap without new machinery, because that event's payload names the finished sub-agent's own transcript path directly, so the existing stage-then-redact path can consume it unchanged and nothing needs to read the harness's undocumented directory layout. We expect reconstruction and telemetry to need no new instrumentation, because the raw transcripts already carry per-message token counts, timestamps, model identifiers, agent attribution and tool-call records. This is shown wrong if the completion event fires before the sub-agent transcript is flushed and readable, if a session spawning many sub-agents degrades under per-completion staging, if the payload is absent on a harness version abcd claims to support, or if the telemetry fields prove inconsistent enough across harness versions that derived measures cannot be compared. + +## Scope Conditions + +- Holds for harness versions whose sub-agent completion event carries the finished sub-agent's transcript path; a version without it falls back to no capture rather than to guessing at the on-disk layout. +- Holds at the observed working scale of a few hundred sub-agents per repository per month, with individual transcripts up to a few megabytes and sessions up to roughly a hundred sub-agents. +- Assumes sub-agent transcripts share the line-delimited shape the session transcript already uses, so one reader serves both. +- Assumes a transcript's owning repository is determined by the working directory recorded inside the transcript, never by decoding the harness's project directory name, which is not reversible. +- Assumes a session run in a worktree belongs to the store of the repository that worktree derives from. +- Telemetry is descriptive of what the harness recorded and is not a billing record; token counts are as reported per message and may omit what the harness did not report. + +## Acceptance Criteria + +- **Given** a session that spawns a sub-agent, **when** that sub-agent finishes, **then** its transcript is stored in the corpus for the session's repository, redacted on write, and listed by `abcd history`. +- **Given** a sub-agent that itself spawns a sub-agent, **when** both finish, **then** both transcripts are stored and each is attributable to the session that spawned it. +- **Given** a stored sub-agent transcript, **when** an operator looks it up from the identifier of the session that spawned it, **then** they can reach it and can tell what kind of agent produced it. +- **Given** a repository whose secret scanner is degraded, **when** a sub-agent transcript would be captured, **then** the capture refuses rather than storing under weakened redaction, matching the session-transcript path. +- **Given** the same sub-agent transcript presented twice, **when** capture runs again, **then** the second capture is a no-op rather than a duplicate record. +- **Given** a sub-agent completion the harness reports without a readable transcript, **when** capture runs, **then** the miss is reported rather than failing silently or aborting the session. +- **Given** transcripts on disk that were never captured, **when** an operator ingests them for a repository, **then** they are redacted under that repository's own configuration and stored in that repository's corpus, and ingesting the same material twice adds nothing. +- **Given** a transcript whose repository cannot be identified, **when** ingest runs without configuration naming a destination for it, **then** it is skipped and reported rather than filed anywhere by guess. +- **Given** a repository configured to adopt a named orphaned project, **when** ingest runs, **then** that project's transcripts are stored in that repository's corpus and the adoption is recorded. +- **Given** a captured session with sub-agents, **when** an operator reconstructs it, **then** they receive one self-contained artefact containing the main thread and every sub-agent, in which each sub-agent's work is attributable to the point in the main thread that spawned it. +- **Given** a reconstructed session, **when** the artefact is produced, **then** a machine-readable telemetry file accompanies it reporting at least token usage, wall-clock duration, turn counts, tool-call counts by tool, models used and agent types. +- **Given** a reconstructed artefact, **when** it is handed to an agent as context, **then** it is readable without access to the original store or the harness's files. + +## Open Questions + +- Does the store's record schema gain explicit fields for the spawning session and the agent kind, or does the existing identifier carry them in composite form?

The per-repo root-SHA keying of +[adr-29](../../decisions/adrs/0029-native-transcript-corpus.md) stands, the +two-stage redaction stands, and `Capture` remains the only path that writes a +record. + +## Scope + +In: `internal/core/history` (the record schema, `Capture`, `Stage`, `Drain`, +`Read`, and the new `Ingest`, `Migrate` and `Reconstruct`); the `hook` sub-tree +and the `history` sub-tree in `internal/surface/cli`; `hooks/hooks.json`; the +per-repo configuration file `.abcd/config/history.json`; the plugin page +`commands/history.md`; the brief chapter +[`04-surfaces/11-history.md`](../../brief/04-surfaces/11-history.md); the +generated command reference and the committed surface snapshot. + +Out: the scanner and its detectors; the store's keying and provisioning; the +harness's retention policy; a corpus-level roll-up across sessions; structured +extraction of findings from a transcript. + +## Approach + +### The lineage fields, and why the composite id goes + +A sub-agent record has to answer three questions a session record never had to: +which session spawned it, which agent inside that session spawned it, and what +kind of agent it was. The workaround already in the store answers the first two +by concatenating them into `session_id`, in the shape +`--agent-`. That fails in both directions. +A reader holding the identifier the harness actually gives them (the full +session id) cannot find the record, because the stored value is a truncation of +it; and a reader holding the record cannot recover the full parent id from it, +because the truncation is lossy. Overloading one field with two identifiers is +the defect, so the fix is fields. + +`Record` gains, all optional and all empty on a main-thread record: + +- `agent_id`: the sub-agent's own identifier, as the harness reports it. +- `parent_agent_id`: the identifier of the agent that spawned it, empty when the + main thread spawned it. +- `agent_type`: the kind of agent, as the harness reports it. +- `spawn_depth`: 0 for the main thread, 1 for a sub-agent of it, and so on. +- `spawn_tool_use_id`: the identifier of the tool call in the spawning + transcript that launched this agent, when it can be established. +- `lineage_source`: `hook`, `ingest` or `migrated`, so an empty `agent_type` on + a sub-agent record is distinguishable from an agent type that was never + recoverable. + +`session_id` keeps its existing meaning unchanged: the session the transcript +belongs to. On a sub-agent record it holds the full, untruncated id of the +spawning session, which is what the `SubagentStop` payload delivers. + +`source_kind` is deliberately NOT extended with a sub-agent value. Kind says +where the bytes came from (`native`, `specstory-import`), not what produced +them; encoding agent-ness there would repeat the overloading this section +removes. + +`recordSchemaVersion` moves to 2. A schema-1 record parses as a main-thread +record with empty lineage, so `List` and `Read` keep working over everything +already stored, and the composite records stay readable until `migrate` runs. + +Three consequential changes follow: + +- **The idempotency key becomes `(source_sha256, session_id, agent_id, kind)`.** + Without `agent_id`, two sub-agents of one session that happened to produce + byte-identical transcripts would collapse into one record, which is the + precise failure the existing key's session component was added to prevent. +- **`recordFilename` becomes `-.md` for a main-thread record + and `--agent-.md` for a sub-agent's.** The + filename is readable convenience only. `listRecords` parses frontmatter and + never the filename, so nothing decodes this string back into fields. +- **`Capture` takes a metadata struct.** `Capture(repoRoot, rootSHA string, raw + []byte, meta CaptureMeta)` replaces the five-positional signature; + `CaptureMeta` carries the session id, the six lineage fields and the kind. Six + more positional string arguments on a security-critical call is a + transposition waiting to happen. + +`Read` resolves its key in three steps: an exact record filename, then an exact +`agent_id`, then a `session_id` (preferring the main-thread record, newest +first). A new `ListForSession(rootSHA, sessionID)` returns the whole set for one +session, main thread first, and is what `history show` uses to list a session's +sub-agents under the record it rendered. + +### The frontmatter is redacted with the body + +Every new field is externally supplied: an agent type comes from the harness +payload, an adopted project name from a configuration file a contributor can +edit. `marshalRecord` writes frontmatter, and frontmatter has never been +scanned, so adding externally-supplied scalars to it would open a redaction +bypass beside a redaction gate. + +The fix is not a second scan. `Capture` prepends the lineage scalars to the raw +text as ordinary lines before the existing two-stage pass runs, then splits them +back off afterwards. The scalars therefore go through exactly the same +sanitise-then-verify discipline as the body, including the caller-home backstop +and the fail-closed residual refusal, with no second code path to drift. A +scalar whose redaction changed it is stored changed; a blocking residual refuses +the whole write as it does today. + +### The deferred decision record + +The move from a composite identifier to explicit lineage fields refines +adr-29 and deserves an ADR. It is deliberately deferred and unminted here: the +shape above is the first thing implementation can falsify, and a decision record +minted before its own migration has run would record a decision that has never +met the store. The ADR is minted after this work merges, and until then **this +spec is the decision of record**. + +One caveat for whoever mints it. The repository's root `AGENTS.md` says ADRs are +the one record family whose ids are hand-numbered and so need coordination +between checkouts; the ADR store's own charter records the ruling of 2026-09-01 +that `abcd decide` mints an ADR through the same collision-proof timestamp-numeric +seam as every other family, with the pre-existing ordinals grandfathered. Those +two statements disagree, and the disagreement is not this spec's to settle. +Resolve it before minting, and correct whichever surface is stale. + +### `hook subagent-stop`, and its wiring + +A new operator-internal verb, `abcd hook subagent-stop`, built to the same shape +as `hook session-end`: fail-closed, always exit 0, diagnostics on stderr, +stdout empty. It reads the hook payload from stdin and uses five of its fields: + +- `agent_transcript_path`: the finished sub-agent's own transcript. This is the + whole reason the gap can be closed without reading the harness's on-disk + layout, and its absence is the fallback case below. +- `agent_id`, `agent_type`: the lineage the payload carries directly. +- `session_id`: the spawning session, stored untruncated. +- `cwd`: resolved to the repository's root-commit SHA through `ahoy.Detect`, + exactly as `hook session-end` does. + +It **stages, it does not capture**, for the reason staging exists: redaction runs +at roughly 0.7 s per megabyte, and `SubagentStop` fires inside a live session +where a stall is felt directly. The next `SessionStart` drains it through the +unchanged `Capture`. + +`parent_agent_id` and `spawn_depth` are not in the payload. They are resolved +down a three-rung ladder, and the rung that answered is recorded: + +1. **The harness's own sidecar**, derived from the payload's transcript path by + substituting the extension, never by walking a directory. When it is present + it carries the spawning agent, the spawn depth and the tool-call identifier + that launched the agent. The read is guarded and best-effort: absence, + unreadability, or a mismatched agent id all leave the fields empty and are + never an error. +2. **The spawning transcript's own tool result** for asynchronously launched + agents, which names the agent id beside the tool-call id. Resolved at + reconstruction time, not in the hook. +3. **Unattributed.** The record stores the sub-agent with empty spawn fields, + and reconstruction lists it in a separate, labelled section rather than + guessing a spawn point. + +Wiring: `hooks/hooks.json` gains a `SubagentStop` entry running +`"$CLAUDE_PLUGIN_ROOT/abcd" hook subagent-stop`, using the same binary +resolution preamble as the existing `SessionEnd` entry, and +`applyHookPlaneFailOpen`'s path list gains `{"hook", "subagent-stop"}` so a +usage error on this verb fails open like every other hook path. Without both, +the verb is dead scaffolding. + +### Staging carries a sidecar + +Staged files are currently identified by parsing their filename, which is why +the filename had to encode the session. Encoding lineage there would rebuild the +composite-identifier defect one directory earlier. + +So `Stage` gains a sidecar. It writes two files, both mode 0o600: + +- `-.raw`, the raw bytes, where `` is the agent id when there + is one and the session id otherwise. +- `-.stage.json`, holding a schema version, the session id, the six + lineage fields, the source path the bytes were read from, and the stage time. + +`listStaged` reads the sidecar when it is present. A `.raw` file with no sidecar +is a staged file from an older binary: its session id is parsed from the +filename exactly as today and it drains as a main-thread transcript, so an +upgrade never strands a backlog. + +Stage idempotency moves from the session id to the `(session_id, agent_id)` pair, +with the existing content compare and the existing last-writer-wins replacement, +all still inside the staging lock. + +### The drain's order and its budget + +Two changes, both forced by the volume this intent admits. + +**Order.** `listStaged` is chronological, and a session's main thread is staged +last because it ends last, so a bounded pass would drain the branches and leave +the spine. The drain therefore takes main-thread entries first, then sub-agent +entries oldest-first. If a pass is truncated, what it stored is the part that +makes the rest legible. + +**Budget.** `sessionStartDrainBudget` becomes a pair: a byte bound and a count +bound, whichever is reached first. The byte bound is the one that protects the +first prompt, because redaction cost tracks bytes rather than files, and the +count bound keeps a pathological many-tiny-files case bounded too. A session +that delegates heavily can stage dozens of transcripts, and a count-only budget +of four would leave the rest unredacted at 0o700 for as many sessions as it +takes to work through them. The remainder is reported as it is today, and the +`SessionStart` notice gains a sentence naming how many staged transcripts are +still unredacted, because a growing pile of raw text is a privacy fact and not a +scheduling detail. + +### `history ingest`: the destination is an operand + +`Ingest` is the recovery path for transcripts that are on disk and were never +captured. Its signature makes the destination explicit and non-derivable: + +``` +history.Ingest(dest Destination, sources []string, opts IngestOptions) (IngestResult, error) +``` + +`Destination` carries the repository root and its root-commit SHA. The scanner +is constructed from `dest.RepoRoot` and from nothing else, so a repository's own +`pii.json` and `gitleaks.json` govern its own transcripts and can never be +applied to another repository's. This is the seam the intent requires, and it is +a seam rather than a default because the working directory is exactly the wrong +authority here: an operator recovering a backlog is not standing in the +repository the transcripts belong to. + +`sources` are explicit file or directory paths. There is no implicit "scan the +harness's store" mode: a vendor path baked into core would be the on-disk-layout +dependency the intent's mechanism rules out. A repository that ingests regularly +declares its roots in `.abcd/config/history.json` so the operator does not +retype them, and the configuration is the only place a path lives. Directory +sources are walked for line-delimited transcripts to a bounded depth; every read +is guarded and capped exactly as the hook path's read is. + +`IngestResult` reports four populations: `captured`, `skipped` (each with a +reason), `orphans`, and `failed`. Nothing is silent. + +### Resolving the owning repository + +Per transcript, in order: + +1. Collect the distinct `cwd` values recorded on the transcript's own lines, + reading a bounded prefix plus the final line rather than the whole file. +2. Resolve each through `ahoy.Detect` to a root-commit SHA. A session run in a + worktree resolves to the repository the worktree derives from, because they + share a root commit, which is the scope condition the intent already records. +3. One root SHA, equal to `dest.RootSHA`: ingest it. +4. One root SHA, different: skip with reason `owned-elsewhere`, reporting the + root SHA. A SHA names a repository without naming it. +5. Two or more distinct root SHAs: skip with reason `ambiguous-owner`. A + transcript is never split between stores. +6. No resolvable `cwd`, or a `cwd` that no longer exists on disk: an orphan, + handled below. + +The harness's project-directory name is never decoded. It is not reversible to a +filesystem path (a directory named for a repository and a path with a separator +in the same position produce the same mangled name), so the recorded `cwd` is +the only sound signal, and it is the one this uses. + +### Orphans are ignored, reported, and adopted only by name + +The default for a transcript whose repository cannot be found on disk is to +**ignore it and say so**. It is listed in `orphans` with its project directory +name as given and its recorded working directory home-redacted, and nothing is +written. + +Adoption is opt-in and per repository, declared in `.abcd/config/history.json`: + +```json +{ + "schema_version": 1, + "ingest_roots": [], + "adopt_projects": [], + "on_orphan": "ignore" +} +``` + +`adopt_projects` lists the project directory names this repository claims. A +transcript under a claimed name is ingested into this repository's store, under +this repository's redaction configuration, and its record is stamped +`lineage_source: ingest` together with `adopted_project`, so the adoption is +recorded on the artefact rather than only in a run's output. + +`on_orphan` accepts `ignore` (the default) or `prompt`. Core never prompts: +under `prompt` it still ingests nothing and returns the orphan list, and the CLI +front door is what asks the operator and re-invokes ingest with the chosen names +in `opts.Adopt`. The transport-agnostic boundary is not negotiable, and an +interactive question is a transport concern. + +Configuration is loaded by `history.LoadConfig(repoRoot)` under the same +discipline the scanner's per-repo configuration already uses: a size cap, a +symlink refusal, and containment inside the repository. + +### `history migrate`: the composite records + +The records already written under composite identifiers are the migration's +input. The count is per-machine local data rather than a fixture; the store this +was designed against held 176 of them. + +`Migrate(rootSHA string, apply bool)` walks the store for a `session_id` matching +`^--agent-$` and, for each: + +- takes `agent_id` from the suffix; +- **repairs the truncated parent id from the record's own body**, which still + carries the full session identifier on its transcript lines, and requires the + recovered value to begin with the stored prefix. A body that disagrees, or one + where no session identifier can be found, leaves the record untouched and is + reported. The truncation is lossy, so the prefix is a check and never a source; +- leaves `agent_type`, `parent_agent_id` and `spawn_depth` empty, since neither + the record nor the store ever held them, and stamps + `lineage_source: migrated` so the emptiness reads as unrecoverable rather than + as a main-thread record; +- rewrites the frontmatter atomically and does not touch the body. + +Three properties matter. `source_sha256` is computed over the raw source and is +not recomputed, so a migrated record still dedups against a re-capture of the +same bytes. The filename is left alone: a rename would break any path a reader +already holds and buys nothing, because listing reads frontmatter. And the verb +**reports by default and writes only under `--apply`**, because the store holds +the only copy of these records. Re-running it is a no-op: a record that already +carries `agent_id` is skipped. + +### `history reconstruct`: one artefact and one telemetry file + +`Reconstruct(rootSHA, sessionID string) (Reconstruction, error)` returns the +artefact bytes and the telemetry structure. Core writes nothing; the CLI writes +the two files into `--out` (default the current directory) or to stdout for `-`. + +The artefact is **Markdown**, named `.md`. The requirement is that +it be handed to a model as context and read without the store or the harness's +files, and Markdown is what a model reads without a schema. Its shape: + +- A header block: schema version, session id, root commit, span, record count, + agent count, and a completeness block saying what was missing. +- `## Main thread`, rendered turn by turn. +- At each spawn point, an inline marker naming the agent type, the agent id and + the time, immediately before the nested section it introduces. +- `## Sub-agent ` sections, nested by `spawn_depth`, each stating who + spawned it, at which point, and over what span. A sub-agent that spawned + sub-agents nests again, to whatever depth the records carry. +- `## Unattributed sub-agents`, last, for anything the attribution ladder could + not place. Labelled, never interleaved. + +Concurrency is represented rather than linearised, which answers the intent's +open question. Sub-agents are ordered by their spawn point in the spawning +transcript, not by their own timestamps; several spawned in one turn are +rendered in the order their spawn points appear in that turn, and the section +says in words that they overlapped, with each carrying its own start and end. +Nothing in the artefact implies that a later section began after an earlier one +ended. + +The artefact is self-contained by construction and by test: it carries no store +path, no harness path and no absolute path of any kind. + +The telemetry file is `.telemetry.json`: + +- `schema_version`, `session_id`, `root_commit` +- `started_at`, `ended_at`, `wall_clock_seconds` +- `turns`: user, assistant, total +- `tokens`: input, output, cache creation input, cache read input +- `tool_calls`: a count per tool name +- `models`: the distinct model identifiers seen +- `agent_types`: the distinct agent types seen +- `agents`: one entry per agent (the main thread included) carrying its id, + parent, type, spawn depth, model, span, turns, tokens and tool-call counts +- `completeness`: records present, sub-agents unattributed, and the named fields + that were absent from the source lines + +`completeness` is not decoration. The intent's scope condition says telemetry +describes what the harness recorded and is not a billing record, and a derived +measure that cannot say what it was missing invites exactly the comparison +across harness versions the condition warns against. + +### Failure modes + +- **The event fires before the transcript is flushed.** The likeliest way this + design is shown wrong, and the first thing implementation measures. Two + mitigations, both cheap. At stage time, a transcript whose final line is not + complete JSON is re-read after a short bounded wait, up to a small fixed + number of attempts. At drain time, the source path recorded in the staging + sidecar is re-read when it still exists, and its bytes replace the staged copy + only when they are strictly longer AND the staged bytes are a prefix of them, + so a recycled path can never substitute a different transcript. Truncation + that survives both is a shorter record, not a corrupt one, and the residual + rate is what the measurement reports. +- **A session with many sub-agents.** Staging is one write per completion, so + the hook's cost is independent of the count. The drain is where the count + lands, which the byte-and-count budget and the drain ordering above address. + The failure this leaves is a backlog of unredacted staged text, which is + reported by `history staged` and named in the `SessionStart` notice. +- **The payload is absent on an older harness.** No `agent_transcript_path` + means the hook warns on stderr, stages nothing and exits 0. Silence is what + this intent exists to end, so the hook also drops a marker beside the staging + directory the first time it sees a payload without the field, and + `history staged` reports it: this harness version does not deliver sub-agent + transcripts, so no sub-agent capture is happening here. +- **An unreadable transcript.** The existing guarded read already refuses a + symlink, a FIFO, a device node, a non-regular file and an over-cap file, and + refuses an over-cap file whole rather than truncating it. Reported on stderr, + nothing staged, exit 0. +- **A degraded scanner.** Unchanged and untouched. Sub-agent capture runs + through the same `Capture`, so the refusal on a degraded scanner or a surviving + blocking span applies by construction; the tests assert it on the sub-agent + path specifically rather than inferring it. + +### Surfaces + +Three new user-facing sub-verbs (`ingest`, `reconstruct`, `migrate`) and one new +operator-internal hook verb. Each needs, in the same change: + +- The `history` sub-tree moved out of `internal/surface/cli/cli.go` into + `internal/surface/cli/history.go` as a pure move with no behaviour change, + before the new verbs are added, so they land in a file that is about one thing. +- Sections in `commands/history.md`, which is the plugin surface for a user verb. + The hook verb's plugin surface is its `hooks/hooks.json` entry, as it is for + `hook session-end`. +- Rows in the brief's history chapter sub-verb table, which `surface_coverage` + checks in both directions and refuses on. +- A regenerated surface snapshot (`cmd/abcd-gen-surface`) and a regenerated + command reference (`cmd/abcd-gen-cli-ref`). + +### Landing order + +Each step leaves the tree green, and each has its own tests. + +1. **The record schema.** Schema version 2, the six fields, `CaptureMeta`, the + widened idempotency key, the frontmatter-through-the-redaction-pass change, + `Read`'s three-step resolution and `ListForSession`. Existing callers updated; + no new verb yet. +2. **Staging's sidecar.** `.stage.json`, the `(session, agent)` idempotency key, + the legacy sidecar-less path, the drain's main-thread-first ordering and the + byte-and-count budget. +3. **The hook.** `abcd hook subagent-stop`, its `hooks.json` entry, its + fail-open path registration, the harness-sidecar rung and the missing-payload + marker. This is the point at which the corpus starts accruing, so it lands + before the recovery verbs. +4. **The measurement.** An instrumented run over real sessions counting how many + staged sub-agent transcripts arrive truncated. If the rate is not near zero, + revisit step 3's mitigations before continuing; the number goes into the + intent's grounds either way. +5. **`history migrate`.** Report mode, then `--apply`, run against the real store + once the tests pass. +6. **`history ingest`.** The destination seam, the owning-repo resolution, the + configuration file, and the orphan policy with its front-door prompt. +7. **`history reconstruct`.** The artefact, then the telemetry file, then the + attribution ladder's second rung. +8. **The surfaces.** The CLI file move happens at the top of step 6; the plugin + page, the brief rows, the surface snapshot and the command reference are + regenerated once, here, and the docs-currency and surface-coverage gates are + what prove it. + +## How the Acceptance Criteria are satisfied + +The intent's criteria in order. + +- **ac-1 (a sub-agent's transcript is stored, redacted, and listed).** The + `SubagentStop` hook stages it; the next drain captures it through the unchanged + fail-closed `Capture`; `List` returns it. Test: + `TestSubagentStopStagesAndDrainStores` drives the verb with a payload and + asserts a record with the lineage fields set. +- **ac-2 (nesting, each attributable to its spawner).** `parent_agent_id` and + `spawn_depth` come from the attribution ladder and are stored per record. Test: + `TestNestedSubagentsAreBothStoredAndAttributed` stages a depth-1 and a depth-2 + agent and asserts the parent chain resolves. +- **ac-3 (found from the spawning session's identifier, with its kind).** + `session_id` holds the untruncated spawning session, so `ListForSession` + returns the main thread and every sub-agent, each carrying `agent_type`. Test: + `TestListForSessionReturnsMainThreadAndEverySubagent`. +- **ac-4 (a degraded scanner refuses).** Unchanged `Capture`. Test: + `TestSubagentCaptureRefusesDegradedScanner` runs the sub-agent path with a + broken per-repo configuration and asserts no record was written. +- **ac-5 (the same transcript twice is a no-op).** The widened idempotency key. + Tests: `TestSubagentCaptureIdempotentOnSourceSHA` and + `TestTwoSubagentsWithIdenticalBytesBothStore`, the second bounding the first so + the key cannot be over-tightened back into the collapsing bug. +- **ac-6 (a completion without a readable transcript is reported, not silent and + not fatal).** The hook's warn-and-exit-0 paths plus the missing-payload marker. + Test: `TestSubagentStopNeverBlocksTheHost`, a table over an absent path, a + FIFO, a symlink, an over-cap file, a malformed payload and a payload with no + `agent_transcript_path`, each asserting exit 0, zero records, and a non-empty + stderr reason. +- **ac-7 (ingest under a repository's own configuration, twice adds nothing).** + `Ingest`'s explicit destination and the unchanged idempotency.

The SessionEnd hook reads the single transcript_path handed to it by the host and never enumerates anything, and hooks.json registers no sub-agent event. Sub-agent transcripts are written by the harness to a sibling directory per session rather than inlined into the parent, so no parent transcript contains them: across all 68 session transcripts on this machine the sidechain marker appears zero times, while 968 sub-agent transcript files hold 673 MB against the parents' 206 MB. What the parent retains per sub-agent is only the launch prompt and the returned report; in one sampled case that is two lines standing in for 399, losing every tool call the agent made. The harness ships a SubagentStop hook event whose payload carries agent_transcript_path, agent_id and agent_type alongside the parent session_id, so the capture path can be closed without depending on the undocumented on-disk layout. Storing the result needs a lineage decision the Record schema cannot currently express: it has no parent, agent or type field, and source_kind is closed to native and specstory-import, so the only representable form is overloading session_id with a composite. This store already holds 105 such hand-made composite records, and because Read matches session_id by exact string they are unreachable from a show of their parent session and their agent type is discarded. The loss was time-bounded until now: the harness deletes transcripts on a rolling retention sweep, so material aged out before anything captured it. + +## Grounds + +- pursued: we expect the SubagentStop payload's agent_transcript_path to let sub-agent transcripts reuse the existing Stage/Drain redact-on-write path unchanged, closing the gap with no new capture mechanism and no dependence on the undocumented on-disk layout; it is shown wrong if the hook fires before the sub-agent transcript is flushed and readable, if a session spawning many sub-agents degrades under per-completion staging, or if the payload proves absent on any supported harness version diff --git a/.abcd/work/issues/open/iss-2609090636110810-agents-md-contradicts-the-decisions-store-on-how-adr-ids-are.md b/.abcd/work/issues/open/iss-2609090636110810-agents-md-contradicts-the-decisions-store-on-how-adr-ids-are.md new file mode 100644 index 00000000..96cfabca --- /dev/null +++ b/.abcd/work/issues/open/iss-2609090636110810-agents-md-contradicts-the-decisions-store-on-how-adr-ids-are.md @@ -0,0 +1,14 @@ +--- +schema_version: 1 +id: "iss-2609090636110810" +slug: "agents-md-contradicts-the-decisions-store-on-how-adr-ids-are" +severity: "major" +category: "drift" +source: "agent-finding" +found_during: "sub-agent transcript capture spec authoring" +origin: researcher-authored +production_mode: hand-written +found_at: "AGENTS.md" +--- + +AGENTS.md contradicts the decisions store on how ADR ids are minted, and the stale surface is the one agents read first. The root conventions file states that ADRs keep a hand-numbered filename ordinal and are the one record family where minting from two checkouts still needs a word first. The decide verb's own help says the opposite: the id is a timestamp-numeric stamp allocated through the shared record-id seam, so two branches deciding on the same day cannot collide, with the hand-numbered records grandfathered and every reader admitting both. The contradiction is not inert. In this session it caused a decision to be deferred that was safe to mint, on a coordination risk that adr-45 had already removed, and the deferral was written into a handover note as fact before it was checked. An agent reads the conventions file at the top of every session and reaches the verb's help only if it doubts what it just read. From 13eafece7ac9786afd13191406e1bc768247b3c2 Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Wed, 9 Sep 2026 08:34:20 +0100 Subject: [PATCH 03/45] feat: the transcript record carries sub-agent lineage in explicit fields A record could name only the session it belonged to, so a sub-agent transcript had nowhere to say which session spawned it or what kind of agent produced it. The only writable identifier was the session id, and hand-capture had been overloading it as --agent-: 176 of the store's 267 records carry that shape, none of them reachable from the identifier of the session that produced them, none recording the agent type at all. Schema version 2 adds seven lineage fields and admits both versions on read. Capture takes a CaptureMeta rather than a positional list. The lineage scalars are framed into the raw text and run through the EXISTING two-stage redaction pass, then split back off, so no field reaches a record without passing the scanner; a frame that does not survive intact refuses the write. Supersession makes (session_id, agent_id) the unit. An agent can stop more than once, and the second stop carries a longer transcript with a different content hash, so a key on the hash alone writes a second record for one agent: 116 of 999 sub-agent transcripts on this machine show two or more stops, and the store already carries the same duplication on the main thread. A body whose stored counterpart is a byte-prefix of it now replaces that record; a shorter re-arrival is a no-op; divergent bodies stay side by side. spawn_attribution distinguishes two empties that would otherwise read alike: an agent spawned by the main thread, and an agent whose lineage is simply unknown. Capture requires it wherever an agent id is set. Migration of the existing composite records, the staging sidecar, the hook and the recovery verbs are later steps and are not in this change.

The hook stages and never captures, and always exits zero: the event is blocking, so a non-zero exit would stop the sub-agent from finishing. Staging carries a .stage.json sidecar rather than encoding lineage in the filename, which would repeat one directory earlier the defect adr-2609090636172016 removes. The sidecar is written before the .raw and torn down if that write fails, since a .raw without one reads down the legacy path, where a sub-agent's agent id would be parsed as a session id. Sidecar-less files still drain, so the raw transcripts already staged on this machine are not stranded. A sidecar that is present but unreadable is reported rather than falling back to the legacy reading, which would misattribute it. The drain takes main-thread entries first and bounds a pass by bytes as well as count. Staged transcripts are unredacted by design, and capturing sub-agents multiplies how many exist at once, so a pass that could only count entries would leave a growing pile of raw text behind. A sub-agent in an isolated worktree records that worktree as its working directory and the harness removes it when the agent stops, so resolving the repo the way session-end does fails exactly where the implementation lanes are. A session-to-store note gives the hook a second route, and refuses an ambiguous claim rather than guessing, because the wrong repo means the wrong scanner. Session capture changes too, deliberately and by decision: session-end now records its source path, so a session resumed with --continue is stored as one complete transcript rather than the truncated first half. This is a behaviour change to existing capture, adopted on the product thinker's call, not a side effect of the sub-agent work. Whether the event fires before the transcript is flushed is still unverified. The mitigations are in (a settle wait outside the staging lock, and a drain-time re-read that only ever extends a stored prefix) and both now count what they catch, so the measurement that gates the remaining steps is cheap to run.

A staged raw transcript can live indefinitely (critical): staging holds unredacted text by design and its contract is that a file survives only until the next session starts, but the drain runs from the session-start hook of the repository the file belongs to. A repository nobody opens again keeps its raw transcripts forever. Four such files sit on this machine now, about thirteen megabytes, the oldest fourteen days old, and the per-repo status verb cannot see a pile in any other repository. Ingest would orphan sub-agents whose session resolves perfectly, because it asks each file's own working directory rather than the session's. That is the right authority for a main thread and the wrong one for a sub-agent, which records a worktree the harness has since removed. Summing reported token usage over-counts it: one response is written as several lines that each repeat the same usage, so a naive sum multiplies by the block count. Measured at 1.77x on one transcript and 5.28x across ten, a factor that varies per session and so cannot be corrected afterwards by a constant. The shared file lock's hundred-millisecond backoff ceiling admits roughly ten writers a second, so a burst past forty or fifty simultaneous completions exceeds the staging timeout and those stages are refused. Pre-existing in the lock helper, but unreachable until something started staging concurrently.

The drain runs from the session-start hook of the repository the staged file belongs to, so a repository that is finished with, or merely quiet, keeps its raw transcripts forever. On this machine right now there are four staged files totalling about thirteen megabytes of unredacted transcript, the oldest fourteen days old, and the per-repo status verb reports nothing from any other repository, so standing in one checkout cannot reveal a pile in another. A drain failure compounds it: the staged file is deliberately left in place, correctly, because deleting the only copy would be worse, but nothing ever retires it, so the population of permanently raw files only grows. Three things would close it: a drain that can run while a session is live rather than only at its start, a maximum staged age after which a file is redacted or deleted with a notice, and a cross-repository notice at session start so the pile in the repository nobody is standing in is still visible. diff --git a/.abcd/work/issues/open/iss-2609090723023943-ingest-resolves-a-transcript-s-owning-repository-from-that-f.md b/.abcd/work/issues/open/iss-2609090723023943-ingest-resolves-a-transcript-s-owning-repository-from-that-f.md new file mode 100644 index 00000000..987369dd --- /dev/null +++ b/.abcd/work/issues/open/iss-2609090723023943-ingest-resolves-a-transcript-s-owning-repository-from-that-f.md @@ -0,0 +1,14 @@ +--- +schema_version: 1 +id: "iss-2609090723023943" +slug: "ingest-resolves-a-transcript-s-owning-repository-from-that-f" +severity: "major" +category: "bug" +source: "agent-finding" +found_during: "sub-agent transcript capture conceptual review" +origin: researcher-authored +production_mode: hand-written +found_at: "internal/core/history" +--- + +Ingest resolves a transcript's owning repository from that file's own recorded working directory, which orphans sub-agents whose parent session is perfectly resolvable. A sub-agent that ran in an isolated worktree records that worktree as its working directory, and the harness removes the worktree when the agent stops, so the directory is already gone by the time anything reads the transcript. On this machine that is 51 worktree-isolated sub-agents whose parent transcript still exists and resolves cleanly, plus 191 more whose shared working directory has gone, plus 6 whose directory merely differs from the parent's. Every one of those files carries the parent session id, so ownership is derivable from the session even when the file's own directory is not. Resolving per file is the right rule for a main thread and the wrong authority for a sub-agent. The resolution should try the session first, through the parent transcript's working directory or any store already holding a record for that session id, and fall back to the file's own directory, so that orphan means the session cannot be placed rather than the file cannot. The same assumption reaches the capture hook, which resolves the payload's working directory the way the session-end hook does: when that directory is a removed worktree the detection fails and the hook exits zero having captured nothing, which loses exactly the implementation-lane agents whose work is most worth keeping. diff --git a/.abcd/work/issues/open/iss-2609090723027424-summing-the-token-usage-reported-in-a-transcript-over-counts.md b/.abcd/work/issues/open/iss-2609090723027424-summing-the-token-usage-reported-in-a-transcript-over-counts.md new file mode 100644 index 00000000..5f5103c0 --- /dev/null +++ b/.abcd/work/issues/open/iss-2609090723027424-summing-the-token-usage-reported-in-a-transcript-over-counts.md @@ -0,0 +1,14 @@ +--- +schema_version: 1 +id: "iss-2609090723027424" +slug: "summing-the-token-usage-reported-in-a-transcript-over-counts" +severity: "major" +category: "bug" +source: "agent-finding" +found_during: "sub-agent transcript capture conceptual review" +origin: researcher-authored +production_mode: hand-written +found_at: ".abcd/development/specs/open" +--- + +Summing the token usage reported in a transcript over-counts it, because the harness repeats one response's usage on every content-block line it writes.

The lock helper backs off exponentially to a hundred-millisecond ceiling, so the rate a contended lock admits is set by that ceiling and not by how short the critical section is. Measured here, sixteen simultaneous stages take 2.12 seconds, consistently across three runs. Extrapolating the same rate, a burst past roughly forty to fifty simultaneous completions begins exceeding the five-second staging lock timeout, and a stage that times out is refused: the transcript it carried is not written anywhere, which is the loss the capture work exists to prevent. Sessions that fan out widely are exactly the sessions whose delegated reasoning is most worth keeping, so the ceiling bites hardest where the value is highest. The condition is pre-existing in the locking helper rather than introduced by sub-agent capture, but nothing reached the lock concurrently before, so it was unreachable in practice until now. The remedies are design-shaped and should be chosen rather than assumed: raise the timeout, lower the backoff ceiling, sharded locks keyed per agent, or a lock-free append with reconciliation at drain.

It recovers the untruncated parent session id from each record's own body, requires the recovery to begin with the stored prefix, and refuses rather than guessing. It reports by default and writes only under --apply; the content hash, the capture stamp and the filename are left alone, because dedup and every existing reader depend on them. The spec was wrong about the composite's shape and about what is recoverable. It gives one form, prefix--agent-id, but 71 of the 176 records carry a workflow segment in the middle, and splitting left to right refuses every one of them: splitting from the right is what reads both. It also records agent type and depth as never held anywhere, when the harness's per-agent metadata still exists for all 176, so the repair recovers the type, the depth and the parent rather than writing a record that says its own lineage is unknown. The workflow segment has no field to land in and is dropped, which the report names. ingest takes its destination as a required operand and refuses to derive one. A transcript must be redacted under its own repository's scanner configuration and never another's, so a destination inferred from the working directory is a privacy fault waiting to happen rather than a convenience. Ownership is resolved for the session before the file. A sub-agent in an isolated worktree records that worktree as its directory and the harness removes it when the agent stops, so asking the file alone orphans agents whose session places cleanly: on this machine 19 of one session's 24 sub-agents have a vanished directory and all 24 resolve through the session. Orphans are ignored and reported, never guessed, and are adopted only when the destination's own config names the project. Records gain adopted_project, so schema 3; parsing stays presence-based and reads 1, 2 and 3 alike.

Telemetry counts one usage per response, not per line. The harness writes a response as several content-block lines that each repeat the same usage object, so summing lines multiplies a response by its block count: on a real session of 55 records, 3711 usage-bearing lines resolve to 1801 responses, an inflation of 2.06x. The factor varies with how many blocks a response happens to have, so a naive total is not merely imprecise, it is wrong by an amount that changes between sessions, which defeats the comparison the file exists to support. The artefact keeps the main thread contiguous and appends each sub-agent, with spawn and join markers in the thread and a timeline table at the head. The spec asked for the sub-agent to be nested physically at its spawn point; that is wrong for asynchronous agents, and the test that proves it shows a delegate's conclusion rendering ahead of a main-thread turn that ran while it was still working. On real data one delegate spans 148 turns of its parent's thread. Nesting survives as data, not as indentation. Where the record is incomplete the artefact says so rather than reading as whole: a completeness block reports absent main threads, unattributed agents, unparseable lines, rejected duplicate records and elided blocks, and every placement records what placed it, so a consumer can weight a heuristic differently from a stored fact.

The artefact reproduced text blocks raw while fencing every other block type, so a transcript could emit the document's own headings and markers byte for byte: a section for an agent that never ran, a turn nobody took, a JOIN marker asserting a result arrived. The artefact's declared reader is a model being handed the session as context, and its own guide told that reader a heading it did not recognise was somebody speaking, which is exactly backwards for a forged heading that matches a real shape. Anyone who got text into one transcript, from a fetched page to a hostile sub-agent, could put words in the record's mouth. Redaction has nothing to say about it: those bytes are content the store correctly kept. Text is now fenced like everything else, reusing the dynamic fence this file already trusts, so there is one escaping mechanism to be right about rather than a judgement per block type about which content is dangerous. A blockquote prefix was considered and rejected: prefixing a line that begins the JOIN marker reproduces the marker exactly, which is the forgery it was meant to close. The guide now states the rule that shipped. Separately, migrate framed the lineage scalars before validating them, the reverse of Capture's order, so a scalar carrying line breaks could re-aim the frame that redaction splits on and write chosen values into agent_type, spawn_tool_use_id, lineage_source and spawn_attribution, discarding the real ones and reporting success. Validation now precedes framing, and frameLineage itself refuses a scalar containing a line break, so the invariant the store claims at its boundary is held in core rather than by the front door alone. Also corrects a comment that was wrong about the harness: exit code 2 is the only blocking status, so the launcher's non-zero exit on a missing binary is a visible diagnostic rather than a stall, and silencing it would hide the fact that transcripts are not being captured. Two reviews independently derived a critical bug from that comment; the code was right and the comment was not.

That was false: the drain runs from the session-start hook of the repository the file belongs to, so a repository nobody opens again keeps its raw transcripts forever. The store holds 14.2 MB across three repositories today, the oldest 26 days, and the per-repo status verb could not see any of it from here. Sub-agent capture, landed earlier on this branch, turns one staged file per session into one per sub-agent completion and stages during a session rather than after it, so this had to be closed before that ships rather than after. A drain now runs while a session is live, from the prompt hook, with a budget small enough not to delay a prompt, and ahead of the rules work so an unparseable rules file cannot switch redaction off. A backlog survey walks every repository in the store and reports counts and sizes only, never another repository's identifiers, since that text renders inside a different repository's session. An age limit buys priority and reporting, not removal. The issue asked for a staged file to be redacted or deleted at the limit; neither is available. Redaction is what the drain already does, and a file is old precisely because nothing ran, not because redaction was tried and failed. Deleting the only copy is the thing staging exists to prevent. So an overdue entry sorts to the front of every drain and is named in the notices, and nothing removes it. A deterministic redaction refusal is now separated from a retryable failure and quarantined with its reason, rather than re-read and re-refused by every later drain while filed as awaiting redaction. This changes state, not exposure: those bytes stay on disk until a human discards them through the one verb that deletes.

That holds only for a repository someone opens again. The drain runs from the session-start hook of the repository the staged file belongs to, so a repository that is finished with, or merely quiet, keeps its raw transcripts forever. On this machine right now there are four staged files totalling about thirteen megabytes of unredacted transcript, the oldest fourteen days old, and the per-repo status verb reports nothing from any other repository, so standing in one checkout cannot reveal a pile in another. A drain failure compounds it: the staged file is deliberately left in place, correctly, because deleting the only copy would be worse, but nothing ever retires it, so the population of permanently raw files only grows. Three things would close it: a drain that can run while a session is live rather than only at its start, a maximum staged age after which a file is redacted or deleted with a notice, and a cross-repository notice at session start so the pile in the repository nobody is standing in is still visible. diff --git a/.abcd/work/issues/open/iss-2609091155497399-reconstruct-loads-every-record-s-full-body-even-in-the-mode.md b/.abcd/work/issues/open/iss-2609091155497399-reconstruct-loads-every-record-s-full-body-even-in-the-mode.md new file mode 100644 index 00000000..f826713b --- /dev/null +++ b/.abcd/work/issues/open/iss-2609091155497399-reconstruct-loads-every-record-s-full-body-even-in-the-mode.md @@ -0,0 +1,14 @@ +--- +schema_version: 1 +id: "iss-2609091155497399" +slug: "reconstruct-loads-every-record-s-full-body-even-in-the-mode" +severity: "minor" +category: "tech-debt" +source: "agent-finding" +found_during: "sub-agent transcript capture branch review" +origin: researcher-authored +production_mode: hand-written +found_at: "internal/core/history/reconstruct.go" +--- + +Reconstruct loads every record's full body even in the mode whose whole purpose is to not render them. The thread loader reads each record body into memory for every thread in a session before the renderer consults the mode, so the spine mode, which reduces each delegate to its opening instruction and closing turn, still pays the full memory cost of every delegate it is about to discard. It is bounded per file by the record read cap rather than unbounded, and the largest main thread observed is well under that cap, so this is a ceiling rather than a leak: a session with a few dozen verbose delegates near the cap could still hold most of a gigabyte resident before the first byte is elided. The ingest path in the same package takes the opposite approach deliberately, processing one transcript at a time and discarding the bytes after probing, because the corpus it walks is far larger than memory. The fix is to let the mode reach the loader, so a spine run decodes only the head and tail turns of a thread it will summarise. Not urgent while sessions stay at the observed fan-out, and worth doing before a session with wide delegation is reconstructed on a small machine. diff --git a/.abcd/work/issues/resolved/iss-2609090722466403-a-staged-raw-transcript-can-live-indefinitely-and-the-store.md b/.abcd/work/issues/resolved/iss-2609090722466403-a-staged-raw-transcript-can-live-indefinitely-and-the-store.md new file mode 100644 index 00000000..6a5d651e --- /dev/null +++ b/.abcd/work/issues/resolved/iss-2609090722466403-a-staged-raw-transcript-can-live-indefinitely-and-the-store.md @@ -0,0 +1,23 @@ +--- +schema_version: 1 +id: "iss-2609090722466403" +slug: "a-staged-raw-transcript-can-live-indefinitely-and-the-store" +severity: "critical" +category: "security" +source: "agent-finding" +found_during: "sub-agent transcript capture conceptual review" +origin: researcher-authored +production_mode: hand-written +found_at: "internal/core/history/staging.go" +resolution: "Staging gains four limbs.

Staging is the one place abcd holds unredacted transcript text on purpose, and its contract is that a staged file survives only until the next session starts. That holds only for a repository someone opens again. The drain runs from the session-start hook of the repository the staged file belongs to, so a repository that is finished with, or merely quiet, keeps its raw transcripts forever. On this machine right now there are four staged files totalling about thirteen megabytes of unredacted transcript, the oldest fourteen days old, and the per-repo status verb reports nothing from any other repository, so standing in one checkout cannot reveal a pile in another. A drain failure compounds it: the staged file is deliberately left in place, correctly, because deleting the only copy would be worse, but nothing ever retires it, so the population of permanently raw files only grows. Three things would close it: a drain that can run while a session is live rather than only at its start, a maximum staged age after which a file is redacted or deleted with a notice, and a cross-repository notice at session start so the pile in the repository nobody is standing in is still visible. + +## Grounds + +- pursued: we expect the pile to be caused by a drain that only ever runs at the owning repository's session start, so moving a small drain into the live prompt hook and surveying every repository at session start should empty it in normal use; it is shown wrong if transcripts still accumulate in a repository being worked in, if the per-prompt budget proves noticeable, or if the quarantined population grows, which would mean redaction is failing on real transcripts rather than the drain failing to run diff --git a/commands/history.md b/commands/history.md index 7a6219b2..5f11513a 100644 --- a/commands/history.md +++ b/commands/history.md @@ -1,7 +1,7 @@ --- name: history -description: Manage the native session-transcript store for this repo by invoking the abcd binary. list, show and staged are read-only; capture, drain and ingest are the redacting write paths, migrate repairs records in place, and reconstruct renders one session as an artefact plus telemetry.

A conceptual review argued they were three separable deliveries, and the landing order had already delivered them as three independent steps that each left the tree green, which is the tell. The record now says what the code did. Capture keeps the original intent and its six criteria: a sub-agent's transcript is stored through the same redact-on-write path as its main thread, at any depth, fail-closed, idempotent, and reporting a miss rather than swallowing it. Recovery takes the three about history already on disk, brought into the repository that owns it under that repository's own redaction configuration. Reconstruction takes the three about the artefact and its telemetry. Capture's scope conditions now say plainly what is not known: whether the completion event fires before the harness has flushed the transcript is UNVERIFIED. The mitigations shipped and count their own effect, but the residual rate has not been measured over a corpus, and an intent that claimed otherwise would be claiming a measurement nobody has taken. Applied to this machine rather than only tested: 176 records repaired out of their composite identifiers, 1066 transcripts ingested, the store grown from 267 records to 1104. Thirteen transcripts were refused by fail-closed redaction over network addresses it could not redact, which is the guard working rather than a shortfall. Each close left a fidelity review owed; those receipts stand open.

On the measured corpus, sub-agent transcripts held roughly three quarters of all recorded bytes — 968 files and 673 MB against 68 session files and 206 MB — outweighing session transcripts by more than three to one. What the parent retains for each delegated task is the launch prompt and the returned report: in one measured case, two lines standing in for several hundred, discarding every tool call the agent made along the way. This is a symmetry failure rather than a missing feature. The corpus already exists, already redacts on write, and already works for one caller class. The sub-agent caller was simply never routed into it. The harness offers a completion event for sub-agents whose payload names the finished sub-agent's own transcript, so the gap can be closed by feeding the existing store, with no new capture mechanism and no dependence on the harness's undocumented on-disk layout. -Two consequences make this urgent rather than tidy.

A session's transcripts are of interest as a set rather than one at a time, both for reading back what happened and as a corpus for studying how humans and agents actually work together. Every measure that study needs is already present in the raw transcripts and is discarded along with them. +Capturing the material is the load-bearing half. What is done with it afterwards — recovering the history that was never captured, and handing a whole session back as one readable artefact — rests on this and is separately delivered. ## Typed Links - **refines `itd-59`** (autonomous-worker transcript capture): the adjacent half of the same corpus. itd-59 covers the worker on abcd's own run seam; this covers sub-agents spawned inside an interactive session. - **refines `adr-29`** (native transcript corpus): feeds the store that ADR established rather than redesigning it. - **corrects a premise in `itd-59`**, flagged for human confirmation and not auto-classified: itd-59's "What's Out of Scope" records interactive-session capture as already solved.

We expect reconstruction and telemetry to need no new instrumentation, because the raw transcripts already carry per-message token counts, timestamps, model identifiers, agent attribution and tool-call records.

The destination repository is an operand with no default, so one repository's scanner configuration governs its own transcripts and can never be applied to another's; a transcript whose owner cannot be established is skipped and named rather than filed by guess; and a transcript whose repository is not on this machine at all is an orphan — ignored, reported, and stored only when a repository claims its project by name. The same run repairs the records already in the store that were filed under a hand-made composite identifier, which neither the reader nor the store could resolve. +> +> "The corpus was going to start on the day I fixed it, and everything I had actually done was going to be the part that was missing," said Maya, an autonomous-development practitioner. "What I could not accept was a recovery tool that guessed. If it cannot tell which repository a transcript belongs to, I want it to say so and leave it alone — a transcript redacted by the wrong repository's rules is worse than a transcript I never recovered." + +## Why This Matters + +`itd-2609090559376002` closes the capture gap prospectively. It does nothing about the past, and the past is where the evidence is: on the machine this was built on, 968 sub-agent transcript files holding 673 MB were on disk and had never been read by abcd, against 68 session files and 206 MB that had. The harness's retention sweep eventually removes them, so "we will get to it" resolves to "we lost it". + +There is a second, smaller population with the same shape. Before the record carried lineage fields, the workaround in use was to invent a composite session identifier by concatenating a truncated parent id with the agent id. 176 of the store's 267 records carried one. That identifier fails in both directions — a reader holding the full session id the harness gives them cannot find the record, and a reader holding the record cannot recover the full parent id, because the truncation is lossy — so those records were in the store and out of reach. They need repairing, not re-ingesting: the store holds the only copy. + +Both are recovery, and recovery is where the redaction question becomes sharp. Live capture takes its repository from the working directory it runs in, and that is correct because the session ran there. An operator recovering a backlog is standing wherever they happen to be standing, which has nothing to do with where the transcripts came from. Deriving the destination from the working directory would silently redact one repository's transcripts under another repository's `pii.json` and `gitleaks.json` — a privacy fault, not a misfiling. So the destination is asked for, every time. `--into .` is a fine answer; an unasked question is not. + +The recovery run this was built against stored 869 transcripts for this repository and 197 for a second one on the same machine, repaired all 176 composite records, and left the store holding 1104 records. Thirteen transcripts were refused outright by the fail-closed scanner over network addresses it could not redact — refused, reported, and not stored, which is the behaviour the corpus is supposed to have. + +## Typed Links + +- **builds_on `itd-2609090559376002`** (sub-agent transcript capture): consumes the lineage fields and the fail-closed `Capture` path that intent put on the record.

We expect the working directory recorded inside a transcript's own lines to be the only sound owner signal, resolved per session before per file, because the harness's project directory name is not reversible to a filesystem path and a sub-agent handed a worktree that the harness has since deleted has no surviving directory of its own.

It also has to be safe: transcript text is content a session participant chose the bytes of, and a document that renders it raw can be made to grow a heading, a turn or a join marker that never happened. Fencing every block, and telling the reader that everything inside a fence is something somebody said, is what makes the structure the document's own rather than the transcript's. + +**Measuring.** Every measure a study of this corpus would want is already in the raw lines — per-response token usage, timestamps, models, agent attribution, tool calls — and was being discarded along with them. Extracting it needs no new instrumentation, but it does need care: the harness writes one line per content block and repeats the same usage on every one, so summing lines counts a response once per block.

The plugin +page `commands/history.md`, the brief chapter +[`04-surfaces/11-history.md`](../../brief/04-surfaces/11-history.md), the +regenerated surface snapshot and the generated command reference. + +Out: the scanner and its detectors; the store's keying and provisioning; the +harness's retention policy; ingest and migrate; reconstruction and telemetry; +structured extraction of findings from a transcript. + +## Approach + +### The lineage fields, and why the composite id goes + +A sub-agent record has to answer three questions a session record never had to: +which session spawned it, which agent inside that session spawned it, and what +kind of agent it was. The workaround already in the store answers the first two +by concatenating them into `session_id`, in the shape +`--agent-`. That fails in both directions. +A reader holding the identifier the harness actually gives them (the full +session id) cannot find the record, because the stored value is a truncation of +it; and a reader holding the record cannot recover the full parent id from it, +because the truncation is lossy. Overloading one field with two identifiers is +the defect, so the fix is fields. + +`Record` gains, all optional and all empty on a main-thread record: + +- `agent_id`: the sub-agent's own identifier, as the harness reports it. +- `parent_agent_id`: the identifier of the agent that spawned it, empty when the + main thread spawned it. +- `agent_type`: the kind of agent, as the harness reports it. +- `spawn_depth`: 0 for the main thread, 1 for a sub-agent of it, and so on. +- `spawn_tool_use_id`: the identifier of the tool call in the spawning + transcript that launched this agent, when it can be established. +- `lineage_source`: `hook`, `ingest` or `migrated`, so an empty `agent_type` on + a sub-agent record is distinguishable from an agent type that was never + recoverable. +- `spawn_attribution`: which rung of the attribution ladder placed the spawn + point — `sidecar`, `transcript` or `unattributed`. Required on a sub-agent + record and empty on the main thread, because "spawned by the main thread" and + "spawn point unknown" would otherwise be the same empty fields. + +`session_id` keeps its existing meaning unchanged: the session the transcript +belongs to. On a sub-agent record it holds the full, untruncated id of the +spawning session, which is what the `SubagentStop` payload delivers. + +`source_kind` is deliberately NOT extended with a sub-agent value. Kind says +where the bytes came from (`native`, `specstory-import`), not what produced +them; encoding agent-ness there would repeat the overloading this section +removes. + +The schema version moves forward. A schema-1 record parses as a main-thread +record with empty lineage, so `List` and `Read` keep working over everything +already stored, and the composite records stay readable until the repair verb +runs. + +Three consequential changes follow: + +- **The idempotency key becomes `(source_sha256, session_id, agent_id, kind)`.** + Without `agent_id`, two sub-agents of one session that happened to produce + byte-identical transcripts would collapse into one record, which is the + precise failure the existing key's session component was added to prevent. +- **`recordFilename` becomes `-.md` for a main-thread record + and `--agent-.md` for a sub-agent's.** The + filename is readable convenience only. `listRecords` parses frontmatter and + never the filename, so nothing decodes this string back into fields. +- **`Capture` takes a metadata struct.** `Capture(repoRoot, rootSHA string, raw + []byte, meta CaptureMeta)` replaces the five-positional signature; + `CaptureMeta` carries the session id, the lineage fields and the kind. Six + more positional string arguments on a security-critical call is a + transposition waiting to happen, and a transposed session and agent id would + silently mis-attribute a transcript rather than fail. + +`Read` resolves its key in three steps: an exact record filename, then an exact +`agent_id`, then a `session_id` (preferring the main-thread record, newest +first). `ListForSession(rootSHA, sessionID)` returns the whole set for one +session, main thread first, and is what `history show` uses to list a session's +sub-agents under the record it rendered. + +### The frontmatter is redacted with the body + +Every new field is externally supplied: an agent type comes from the harness +payload, an adopted project name from a configuration file a contributor can +edit. `marshalRecord` writes frontmatter, and frontmatter has never been +scanned, so adding externally-supplied scalars to it would open a redaction +bypass beside a redaction gate. + +The fix is not a second scan. `Capture` prepends the lineage scalars to the raw +text as ordinary lines before the existing two-stage pass runs, then splits them +back off afterwards. The scalars therefore go through exactly the same +sanitise-then-verify discipline as the body, including the caller-home backstop +and the fail-closed residual refusal, with no second code path to drift. A +scalar whose redaction changed it is stored changed; a blocking residual refuses +the whole write as it does today. A scalar carrying a line break would forge a +frontmatter field, so it is refused at the store and dropped at the hook — +losing one decorative field beats losing the transcript. + +### The deferred decision record + +The move from a composite identifier to explicit lineage fields refines +adr-29 and deserves an ADR. It is deliberately deferred and unminted here: the +shape above is the first thing implementation can falsify, and a decision record +minted before its own migration has run would record a decision that has never +met the store. The ADR is minted after this work merges, and until then **this +spec is the decision of record**. + +One caveat for whoever mints it. The repository's root `AGENTS.md` says ADRs are +the one record family whose ids are hand-numbered and so need coordination +between checkouts; the ADR store's own charter records the ruling of 2026-09-01 +that `abcd decide` mints an ADR through the same collision-proof timestamp-numeric +seam as every other family, with the pre-existing ordinals grandfathered. Those +two statements disagree, and the disagreement is not this spec's to settle. +Resolve it before minting, and correct whichever surface is stale. + +### `hook subagent-stop`, and its wiring + +A new operator-internal verb, `abcd hook subagent-stop`, built to the same shape +as `hook session-end`: fail-closed, diagnostics on stderr, stdout empty. One +difference is not cosmetic. `SessionEnd`'s exit code is ignored by contract; +`SubagentStop`'s is not — exit 2 is that event's BLOCKING status and would stop +the sub-agent from finishing. So every path in the verb returns nil, and no +staging failure is worth risking an agent's completion over. That is a rule about +this binary's own exits and not about the launcher's: the `hooks.json` wrapper's +`exit 1` when no binary resolves is deliberately non-zero and deliberately not 2, +because it is the one signal a user gets that their transcripts are not being +captured. + +It reads the hook payload from stdin and uses five of its fields: + +- `agent_transcript_path`: the finished sub-agent's own transcript. This is the + whole reason the gap can be closed without reading the harness's on-disk + layout, and its absence is the fallback case below. +- `agent_id`, `agent_type`: the lineage the payload carries directly. +- `session_id`: the spawning session, stored untruncated. +- `cwd`: resolved to the repository's root-commit SHA. + +It **stages, it does not capture**, for the reason staging exists: redaction runs +at roughly 0.7 s per megabyte, and `SubagentStop` fires inside a live session +where a stall is felt directly. A later drain runs it through the unchanged +`Capture`. + +**Resolving the store needed a second rung the plan did not have.** A sub-agent +given its own worktree records that worktree as its `cwd`, and the harness +REMOVES the worktree when the agent stops — so the directory is frequently gone +by the time the hook runs, and the agents that affects are the isolated +implementation lanes, whose transcripts are worth the most. So: the `cwd` first, +exactly as `hook session-end` does, and failing that the spawning session. A hook +that CAN resolve a repository writes a zero-byte note naming the session under +`~/.abcd/history//sessions/`, and a later hook holding only that session id +finds the store with one stat per repository and no transcript read. A session id +two stores claim is REFUSED rather than guessed, because a transcript filed +against the wrong repository is redacted by the wrong repository's scanner +configuration. Notes are pruned past thirty days. + +A payload with no usable `agent_id` stages nothing: without an agent id the +stage has no key of its own and would collide with the spawning session's own +staged transcript, overwriting the spine to save a branch. + +`parent_agent_id`, `spawn_depth` and `spawn_tool_use_id` are not in the payload. +They are resolved down a three-rung ladder, and the rung that answered is +recorded in `spawn_attribution`: + +1. **The harness's own sidecar**, derived from the payload's transcript path by + substituting the extension, never by walking a directory. When it is present + it carries the spawning agent, the spawn depth and the tool-call identifier + that launched the agent. The read is guarded and best-effort: absence, + unreadability, a non-regular file, a parse failure or a missing depth all + leave the fields empty and are never an error. +2. **The spawning transcript's own tool result** for asynchronously launched + agents, which names the agent id beside the tool-call id. Resolved at + reconstruction time, not in the hook — it is + `itd-2609091718595846`'s to deliver, and it did. +3. **Unattributed.** The record stores the sub-agent with empty spawn fields and + `spawn_attribution: unattributed`, and a reader lists it separately rather + than guessing a spawn point. + +Wiring: `hooks/hooks.json` gains a `SubagentStop` entry running +`"$CLAUDE_PLUGIN_ROOT/abcd" hook subagent-stop`, using the same binary +resolution preamble as the existing `SessionEnd` entry, and +`applyHookPlaneFailOpen`'s path list gains `{"hook", "subagent-stop"}` so a +usage error on this verb fails open like every other hook path. Without both, +the verb is dead scaffolding. + +### Staging carries a sidecar + +Staged files were identified by parsing their filename, which is why the +filename had to encode the session. Encoding lineage there would rebuild the +composite-identifier defect one directory earlier. + +So `Stage` gains a sidecar. It writes two files, both mode 0o600: + +- `-.raw`, the raw bytes, where `` is the agent id when there + is one and the session id otherwise. +- `-.stage.json`, holding a schema version, the session id, the + lineage fields, the source path the bytes were read from, and the stage time. + +`listStaged` reads the sidecar when it is present. A `.raw` file with no sidecar +is a staged file from an older binary: its session id is parsed from the +filename exactly as before and it drains as a main-thread transcript, so an +upgrade never strands a backlog. A sidecar that is PRESENT but unreadable is a +different fact and is not drained at all — falling back to the filename there +would read a sub-agent's key as a session id and file the transcript under a +session that does not exist. + +Stage idempotency moves from the session id to the `(session_id, agent_id)` pair, +with the existing content compare and the existing last-writer-wins replacement, +all still inside the staging lock. + +### The drain's order and its budget + +**Order.** `listStaged` is chronological, and a session's main thread is staged +last because it ends last, so a bounded pass would drain the branches and leave +the spine. The drain therefore takes overdue entries first, then main-thread +entries, then sub-agent entries oldest-first. If a pass is truncated, what it +stored is the part that makes the rest legible. + +**Budget.** `DrainBudget` is a pair: a byte bound and a count bound, whichever is +reached first. The byte bound is the one that protects the first prompt, because +redaction cost tracks bytes rather than files, and the count bound keeps a +pathological many-tiny-files case bounded too. A pass with nothing yet attempted +never declares itself exhausted, so a single staged transcript larger than the +byte bound cannot be skipped by every pass forever. + +### Staged text does not live indefinitely + +Staging is the one place abcd holds unredacted transcript text on purpose. The +code claimed it lived "only until the next session starts", and the drain ran +from a hook of the repository the file belongs to — so a repository nobody +opened again kept its raw transcripts for as long as the disk lasted +(`iss-2609090722466403`). Four such files, thirteen megabytes, the oldest a +fortnight old. An intent that admits one staged file per sub-agent completion +makes that ordinary rather than pathological, so four mechanisms bound it: + +- **A drain runs while a session is LIVE**, not only at its start: the + prompt-router hook drains one entry and at most half a megabyte per prompt, so + a session that spawns sub-agents redacts its own branches as it goes. + Everything it says goes to stderr, never to the hook's stdout. +- **`StagedTTL` (seven days) is the maximum staged age.** Past it an entry is + OVERDUE: it sorts to the front of every drain and is named in every notice. Age + buys priority and volume and nothing else — an overdue transcript is never + deleted, never redacted down, never degraded. Losing the only copy is worse + than keeping it, which is the premise staging is built on. +- **Session start reports EVERY repository in the store**, not just the one the + operator is standing in, and `abcd history staged --all-repos` is the + read-only verb behind the same survey. A per-repo listing is blind to exactly + the pile that grows: the one nobody opens. The survey carries counts, sizes and + repository names — never another repository's session ids. +- **A transcript the fail-closed scanner will never pass is QUARANTINED**, not + retried forever. A residual refusal is a property of the transcript's own + bytes, so every future drain reaches the same refusal; such an entry moves to + `quarantine/` with a written reason and leaves the queue. `DrainFailure` + therefore distinguishes retryable from permanent, which reporting them alike + did not (`iss-2609090722466403`). `abcd history discard --yes` is the only + thing that removes one. + +### Failure modes + +- **The event fires before the transcript is flushed.** The likeliest way this + design is shown wrong, and it is **still UNVERIFIED** — the documentation + suggests it may, the binary does not settle it, and the rate has not been + measured over a corpus. Two mitigations, both cheap and both self-counting. At + stage time, `TranscriptSettled` tests whether the final non-blank line is + complete JSON; a transcript that is not is re-read up to four times at 25 ms + intervals, and a copy that never settles is staged anyway with a stderr line + saying it may be short. The wait lives in the surface and deliberately NOT + inside `Stage`, whose critical section is under a lock tuned for a single + `SessionEnd`: a wait in there would turn a burst of simultaneous completions + into a queue. At drain time, the source path recorded in the staging sidecar is + re-read when it still exists, and its bytes replace the staged copy only when + they are strictly longer AND the staged bytes are a byte-prefix of them, so a + recycled path can never substitute a different transcript. `DrainResult.Extended` + counts the transcripts that were caught short and completed, which is the + measurement that will eventually settle the question. +- **A session with many sub-agents.** Staging is one write per completion, so + the hook's cost is independent of the count. The drain is where the count + lands, which the byte-and-count budget and the drain ordering address. The + failure this leaves is a backlog of unredacted staged text, which the four + mechanisms above bound and report. +- **The payload is absent on an older harness.** No `agent_transcript_path` + means the hook warns on stderr, stages nothing and exits 0. Silence is what + this intent exists to end, so it also writes a marker beside the staging + directory recording the first and last sighting and a count, and + `history staged` reports it: this harness version does not deliver sub-agent + transcripts, so no sub-agent capture is happening here. Absence of sub-agent + records then has an explanation on disk instead of looking like an absence of + sub-agents. +- **An unreadable transcript.** The existing guarded read already refuses a + symlink, a FIFO, a device node, a non-regular file and an over-cap file, and + refuses an over-cap file whole rather than truncating it. Reported on stderr, + nothing staged, exit 0. +- **A degraded scanner.** Unchanged and untouched. Sub-agent capture runs + through the same `Capture`, so the refusal on a degraded scanner or a surviving + blocking span applies by construction; the tests assert it on the sub-agent + path specifically rather than inferring it. + +### Surfaces + +One operator-internal hook verb, whose plugin surface is its `hooks.json` entry, +as it is for `hook session-end`; plus the `history staged` and `history discard` +changes above. Each needs, in the same change: sections in +`commands/history.md`; rows in the brief's history chapter sub-verb table, which +`surface_coverage` checks in both directions and refuses on; a regenerated +surface snapshot (`cmd/abcd-gen-surface`) and command reference +(`cmd/abcd-gen-cli-ref`). + +### Landing order + +Each step left the tree green, and each had its own tests. + +1. **The record schema.** The lineage fields, `CaptureMeta`, the widened + idempotency key, the frontmatter-through-the-redaction-pass change, `Read`'s + three-step resolution and `ListForSession`. Existing callers updated; no new + verb yet. +2. **Staging's sidecar and the hook.** `.stage.json`, the `(session, agent)` + idempotency key, the legacy sidecar-less path, the drain's ordering and the + byte-and-count budget; then `abcd hook subagent-stop`, its `hooks.json` entry, + its fail-open path registration, the session-note fallback, the harness-sidecar + rung and the missing-payload marker. This is the point at which the corpus + starts accruing. +3. **The staged-lifetime bound.** The live drain, `StagedTTL` and the overdue + ordering, the all-repositories survey, and quarantine. +4. **The measurement**, still outstanding: an instrumented run over real sessions + counting how many staged sub-agent transcripts arrive truncated. + `DrainResult.Extended` is the counter; the number goes into the intent's + grounds when it exists. + +## How the Acceptance Criteria are satisfied + +- **ac-1 (a sub-agent's transcript is stored, redacted, and listed).** The + `SubagentStop` hook stages it; the next drain captures it through the unchanged + fail-closed `Capture`; `List` returns it. Tests: + `TestHookSubagentStopStagesLineage`, + `TestHookSubagentStopStagesRatherThanCaptures` and + `TestSubagentStopThenSessionStartStoresTheRecord`, the last driving the whole + path end to end. +- **ac-2 (nesting, each attributable to its spawner).** `parent_agent_id` and + `spawn_depth` come from the attribution ladder and are stored per record. + Tests: `TestHookSubagentStopReadsTheHarnessSidecar`, + `TestLineageRoundTripsThroughTheRecord`, + `TestUnknownSpawnIsDistinguishableFromNoParent` and + `TestUnreadableSidecarIsReportedNotMisattributed`. +- **ac-3 (found from the spawning session's identifier, with its kind).** + `session_id` holds the untruncated spawning session, so `ListForSession` + returns the main thread and every sub-agent, each carrying `agent_type`.

The scanner +is constructed from `dest.RepoRoot` and from nothing else, so a repository's own +`pii.json` and `gitleaks.json` govern its own transcripts. This is a seam rather +than a default because the working directory is exactly the wrong authority +here: an operator recovering a backlog is not standing in the repository the +transcripts belong to, and deriving the destination from where they happen to be +would redact one repository's transcripts under another's rules — a privacy +fault, not a misfiling. + +The CLI matches: `--into` is REQUIRED and has no default, the run prints which +repository it wrote into, and an empty value is a hard refusal that names +`--into .` as a perfectly good answer. `TestIngestRefusesWithoutAnExplicitDestination` +holds the core half and `TestHistoryIngestRefusesWithoutAnExplicitDestination` +the surface half; `TestHistoryIngestWritesIntoTheNamedRepositoryNotTheWorkingDirectory` +is the one that would catch a regression to a cwd default. + +`sources` are explicit file or directory paths. There is no implicit "scan the +harness's store" mode: a vendor path baked into core would be the on-disk-layout +dependency the intent's mechanism rules out. A repository that ingests regularly +declares its roots in `.abcd/config/history.json` so the operator does not +retype them, and the configuration is the only place a path lives. Directory +sources are walked for `.jsonl` files to a bounded depth (`ingestDefaultDepth`, +8); a symlinked source is refused outright and a symlinked directory is never +descended; every read goes through the same guarded, capped reader the hook path +uses. + +`IngestResult` reports four populations — `Captured`, `Skipped` (each with a +reason), `Orphans`, and `Failed` — and the `--json` envelope normalises all four +to arrays so a consumer never has to distinguish absent from empty.

The corpus +refuted it before the code shipped, and the fix is +`iss-2609090723023943`: a sub-agent handed its own worktree records that +worktree as its `cwd`, the harness deletes the worktree when the agent stops, so +by recovery time the directory the transcript names does not exist. Resolving +per file orphans exactly the isolated implementation lanes — the transcripts +worth the most. + +So the resolution runs a session-level pass first and a per-file pass only for +what it could not place: + +1. **`session-cwd`.** Collect the distinct `cwd` values recorded on the + MAIN-THREAD files of that session and resolve each through `ahoy.Detect`. One + root SHA places the whole session, sub-agents included; two or more mark it + ambiguous. +2. **`store`.** Failing that, the store itself: the session notes under + `~/.abcd/history//sessions/` and the `session_id` of every stored record + are indexed once per run, and a session exactly one store claims is placed by + it. This is the rung that recovers a session whose directories are all gone. +3. **`file-cwd`.** Only for a file whose session neither rung placed: resolve the + file's own recorded `cwd` values. + +Then, per transcript: an ambiguous owner is skipped with reason +`ambiguous-owner` — a transcript is never split between stores. A resolved owner +that is not the destination is skipped with reason `owned-elsewhere`, reporting +the root SHA, which names a repository without naming it. A file that names no +session, or two agents, is skipped as a file-integrity refusal (`no-session-id`, +`ambiguous-agent-id`). Anything left unplaced is an orphan. + +The harness's project-directory name is never decoded. It is not reversible to a +filesystem path — a directory named for a repository and a path with a separator +in the same position produce the same mangled name — so the recorded `cwd` is +the only sound signal, and it is the one this uses. The name survives only as an +opaque LABEL, which is what adoption claims. + +A knowing divergence, documented in the code: `probeTranscript` reads the whole +file rather than the bounded prefix plus final line the plan called for, because +a `cwd` can appear anywhere in a transcript and a prefix read placed fewer files. +The invariant it does keep is that one transcript is resident at a time. + +### Orphans are ignored, reported, and adopted only by name + +The default for a transcript whose repository cannot be found on this machine is +to **ignore it and say so**. It is listed in `Orphans` with its project +directory name as given and its recorded working directory home-redacted, and +nothing is written. + +Adoption is opt-in and per repository, declared in `.abcd/config/history.json`: + +```json +{ + "schema_version": 1, + "ingest_roots": [], + "adopt_projects": [], + "on_orphan": "ignore" +} +``` + +`adopt_projects` lists the project directory names this repository claims; +`--adopt` adds names for one run. A transcript under a claimed name is stored in +this repository's store, under this repository's redaction configuration, and its +record carries `lineage_source: ingest` together with `adopted_project`, so the +adoption is a property of the artefact rather than of a run's output. Adoption is +reachable only when the owner is unresolved AND unambiguous, so an ambiguous +transcript is never adopted around its ambiguity. + +`on_orphan` accepts `ignore` (the default) or `prompt`. **Core never prompts:** +under `prompt` it still ingests nothing and returns the orphan list, and the CLI +front door is what asks the operator on stderr and re-invokes `Ingest` with the +chosen names in `opts.Adopt`. The transport-agnostic boundary is not negotiable, +and an interactive question is a transport concern — +`TestHistoryIngestPromptsForOrphansOnlyUnderThatPolicy` is the armed detector. + +`LoadConfig(repoRoot)` reads the file under the same discipline the scanner's +per-repo configuration uses: rooted at the repository, size-capped at 64 KiB, a +symlinked leaf refused. An ABSENT file is not an error — it is +`DefaultConfig()`, `{schema_version: 1, on_orphan: "ignore"}` — but a file that +is present and unreadable, malformed, or carries an unknown `on_orphan` is. + +### `history migrate`: the composite records + +The records already written under composite identifiers are the migration's +input. The count is per-machine local data rather than a fixture; the store this +was designed against held 176 of them out of 267 records. + +`Migrate(rootSHA string, opts MigrateOptions)` walks the store for a `session_id` +matching the composite shape `--agent-` and, for each: + +- takes the agent id from the suffix; +- **repairs the truncated parent id from the record's own body**, which still + carries the full session identifier on its transcript lines, and requires the + recovered value to begin with the stored prefix. A body that disagrees, or one + where no session identifier can be found, leaves the record untouched and is + reported. The truncation is lossy, so the prefix is a check and never a source; +- recovers `agent_type`, `parent_agent_id`, `spawn_depth` and + `spawn_tool_use_id` through the `LineageLookup` seam when a + `--sidecar-root` (or a declared `ingest_root`) holds the harness's per-agent + metadata, and otherwise stamps `spawn_attribution` to say the lineage is + UNKNOWN — so an empty agent type reads as unrecoverable rather than as a + main-thread record; +- frames every recovered scalar through the same redaction pass the body gets + before it is written, because a lineage scalar learned from a file a + contributor can edit is externally-supplied text landing in frontmatter; +- rewrites the frontmatter atomically and does not touch the body. + +Three properties matter. `source_sha256` is computed over the raw source and is +not recomputed, so a migrated record still dedups against a re-capture of the +same bytes. The filename is left alone: a rename would break any path a reader +already holds and buys nothing, because listing reads frontmatter. And the verb +**reports by default and writes only under `--apply`**, because the store holds +the only copy of these records. Re-running it is a no-op. + +`migrate`'s destination is implicit — the store of the repository the operator is +standing in — where `ingest`'s is explicit. The two are not inconsistent: +`migrate` rewrites records already filed in one store and chooses nothing, while +`ingest` decides which store bytes enter. + +### Surfaces + +Two new user-facing sub-verbs. Each carries, in the same change: a section in +`commands/history.md`; rows in the brief's history chapter sub-verb table, which +`surface_coverage` checks in both directions and refuses on; a regenerated +surface snapshot (`cmd/abcd-gen-surface`) and command reference +(`cmd/abcd-gen-cli-ref`). The `history` sub-tree moved out of +`internal/surface/cli/cli.go` into its own file before the verbs were added, so +they landed in a file that is about one thing. + +## How the Acceptance Criteria are satisfied + +- **ac-1 (ingest under the destination's own configuration; twice adds + nothing).** `Ingest`'s explicit `Destination`, the scanner built from + `dest.RepoRoot` alone, and the unchanged `(source_sha256, session_id, agent_id, + kind)` idempotency key. Tests: + `TestIngestRedactsUnderTheDestinationsOwnConfiguration` (two fixture + repositories with different rules, asserting the destination's applied and the + source's not), `TestIngestStoresOnlyWhatTheDestinationOwns`, and + `TestIngestIsIdempotent`. +- **ac-2 (an unidentifiable owner is skipped and reported).** The resolution + ladder's refusals. Tests: `TestIngestRefusesAnAmbiguousOwner`, + `TestIngestIgnoresAndReportsOrphans`, `TestIngestSkipsAFileThatIsNotOneTranscript`, + with `TestIngestPlacesTheSessionBeforeTheFile` and + `TestIngestPlacesASessionFromTheStoreWhenNoDirectorySurvives` bounding the + refusal so it cannot be satisfied by refusing everything. +- **ac-3 (a configured adoption stores and records it).** `adopt_projects` plus + the `adopted_project` stamp on the record. Test: + `TestIngestAdoptsOnlyProjectsNamedByTheDestination` asserts both directions — + the claimed project is stored and stamped, and an unclaimed one is not stored + at all. + +`migrate` carries no acceptance criterion of its own.

Two things in the shipped shape are deliberate reversals of what was +planned, and both are recorded below: the sub-agent sections are appended after a +contiguous main thread rather than nested at their spawn points, and token usage +is de-duplicated per response rather than summed per line. + +## Scope + +In: `internal/core/history` — `Reconstruct`, `ReconstructOptions`, +`Reconstruction`, `Telemetry`, `AgentTelemetry`, `TokenCounts`, `TurnCounts`, +`Completeness`, `DroppedRecord` (`reconstruct.go`) and the artefact renderer +(`reconstruct_render.go`). The `reconstruct` sub-verb in +`internal/surface/cli/history_reconstruct.go`, wired from `history.go`. The +plugin page `commands/history.md`, the brief chapter +[`04-surfaces/11-history.md`](../../brief/04-surfaces/11-history.md), the +regenerated surface snapshot and command reference. + +Out: every write path into the store; the scanner and redaction (reconstruction +reads records that were already redacted on write); the record schema; capture; +ingest and migrate; any roll-up across sessions. + +## Approach + +### The signature carries the size problem + +```go +type ReconstructMode string +const ( ModeFull ReconstructMode = "full"; ModeSpine ReconstructMode = "spine" ) + +type ReconstructOptions struct { + SessionID string + Mode ReconstructMode // "" → ModeFull + MaxBlockBytes int // 0 = unbounded; negative is an error +} + +func Reconstruct(rootSHA string, opts ReconstructOptions) (Reconstruction, error) +``` + +The plan's `Reconstruct(rootSHA, sessionID)` did not survive contact with a real +session: a 55-record session renders to 7.7 MB, and the whole point of the +artefact is that it be handed to a model. Both remedies are caller choices, so +they are options rather than constants. `spine` mode keeps the main thread whole +and reduces each delegate to its first and last turn, with counted gap markers; +`MaxBlockBytes` (8 KiB at the front door) caps one rendered tool input or result, +marked where it happens and counted in the telemetry. There is deliberately no +per-agent mode: `abcd history show ` already answers that. + +`Reconstruction` returns the artefact bytes, both filenames, the artefact size +and the `Telemetry` structure. `Artefact` is `json:"-"`, so the `--json` envelope +carries the telemetry and the names but never the document. + +### Record selection, and saying what was not used + +One session's records are loaded and reduced to one thread per `(session, +agent)`: readable first, then longest body, then newest capture, then filename +descending. Every loser is reported in `Completeness.DroppedRecords` with a +reason and named in the document's own `## Completeness` section. Nothing is +dropped silently — a session whose superseded records vanished from the artefact +without a word would be a reconstruction that quietly disagreed with the store. + +A session with no main-thread record still renders, labelled, with a completeness +note. Only a session with no records at all is an error. + +### The layout: appended sections, doubly marked — a reversal + +The plan called for `## Sub-agent ` sections nested at their spawn +points by `spawn_depth`. **The corpus refuted it.** The sub-agents whose id a +spawning transcript records are the ASYNCHRONOUS ones, and for those the spawn +and the join are many turns apart — one measured case spawned at turn 18 and +joined at turn 167. Splicing the section in at the spawn point puts a delegate's +conclusions in front of 148 main-thread turns that ran before those conclusions +existed, which is precisely the false inference the artefact exists to prevent. + +So the main thread stays contiguous and is never spliced, and each sub-agent gets +its own appended `## Agent ` section. Attribution is carried three +ways instead of by indentation: + +- **Two inline markers in the spawning thread.** `[SPAWNED agent () + here — its transcript is in section "Agent ". Everything below this line up + to its JOIN marker ran without its result.]` and `[JOINED agent here — its + result reached this thread at this turn.]`, collapsed into one marker when the + spawn and the join are the same turn (a synchronous delegate). +- **A per-agent provenance block** naming the type, spawn depth, spawner, spawn + turn and tool call, join turn, span, turns, tokens and source record — plus a + `CONCURRENCY:` line stating how many turns of the spawning thread ran between + the spawn and the join without this agent's result. +- **`## Agent timeline`**, a table at the head of the document with one row per + thread carrying spawn, start, end, join, turns and tokens. + +Nesting survives as DATA (`spawn_depth`, the parent, the spawning thread), not as +layout. Concurrency is read off the timeline; **section order asserts nothing +about time**, and the document says so in words. + +Placement is a two-rung ladder. Rung 1 is the record's own stored spawning tool +call, matched against the host thread's tool-use blocks (`placed_by: record`). +Rung 2 is the host transcript's own tool result naming the agent id, resolved +back to the call that issued it (`placed_by: transcript`) — the spec's deferred +"resolved at reconstruction time" rung, delivered. The host is the parent agent's +thread when that parent is in the set, the main thread when no parent is named, +and NOTHING when a parent is named but absent: placing such an agent on the main +thread would assert a spawn that did not happen. + +An agent neither rung places goes under `## Unattributed sub-agents`, last and +labelled, never interleaved. Membership is decided by "no recoverable spawn +point", which is not the same fact as the record's own `spawn_attribution`; the +telemetry counts the two separately (`agents_unattributed` versus +`agents_without_spawn_point`). + +### Structure the transcript cannot forge + +A text block is the one kind of content a session participant chose the bytes of. +Rendered raw it can emit `## Agent `, `### Turn 99 — assistant`, or a +`[JOINED …]` marker byte-for-byte, fabricating an agent that never ran or a +result that never arrived. Redaction has nothing to say about this: the text is +not secret, it is structural. + +The answer is containment, applied uniformly. **Every** block — text included — +goes through one fenced writer that measures the longest backtick run in the +content and opens with one more, so content carrying its own fences cannot close +the block containing it. One escaping mechanism everywhere beats a per-type +judgement about which content is dangerous, because the judgement is what drifts. + +The second half is declarative. The artefact carries a `## How to read this +document` section that enumerates the structures the document itself asserts and +states the invariant: everything inside a fence is something somebody said, +everything outside one is this document. A forged heading inside a fence is +quoted content asserting nothing, however exactly it matches. +`TestReconstructCannotBeForgedByTranscriptText` plants forged headings, a forged +turn heading, a forged join marker and a fence of its own, and asserts none of +them appears as a line OUTSIDE a fence — while also asserting the content is +still reproduced, because this is containment and not redaction. + +### Self-containment and determinism + +Records are named by basename everywhere; the artefact carries no store path, no +harness path and no absolute path of any kind, and the CLI additionally +home-redacts every path it prints or marshals. The artefact carries **no +generation timestamp** — that lives on the telemetry alone — so the same records +reconstruct to identical bytes. `TestReconstructionIsSelfContained` and +`TestReconstructIsDeterministic` are the two detectors. + +### Telemetry, and the counting bug it exists to avoid + +`.telemetry.json`, schema 1, carrying `session_id`, `root_commit`, +`mode`, `generated_at`, the span and `wall_clock_seconds`, `turns`, `tokens`, +`tool_calls` (a count per tool name), `models`, `agent_types`, one `agents` entry +per thread (the main thread included) with its own copy of every measure, and a +`completeness` block. + +**Tokens are counted once per distinct response id, never once per transcript +line.** The harness writes one line per content block and repeats the response's +usage on every one of them, so a naive sum multiplies a response by its block +count — and the factor varies per session, so no constant could correct it. On a +real 55-record session, 3711 usage-bearing lines resolve to 1801 distinct +responses: an inflation of 2.06x (`iss-2609090723027424`). Turns de-duplicate the +same way, so a multi-line assistant response is one turn, and tool calls +de-duplicate on the tool-use block's own id. + +Both counts are published side by side — `api_responses` and `usage_lines_seen` — +so a consumer can SEE that the de-duplication happened rather than take it on +trust. Usage carrying no message id is counted anyway (dropping it would +understate), tallied into `completeness.usage_without_message_id`, and given a +note saying the totals are an upper bound to that extent. That is the one +condition under which they can still be inflated, and it says so. + +`completeness` is not decoration. The intent's scope condition says telemetry +describes what the harness recorded and is not a billing record, and a derived +measure that cannot say what it was missing invites exactly the cross-version +comparison the condition warns against. It reports whether the main thread was +present, records found against records used and why each loser was dropped, the +agent counts that failed each attribution question, unparseable lines, +un-de-duplicable usage, the field NAMES that were absent from the source lines +(distinguishing "zero happened" from "this harness does not record it"), and the +elision and omission counts. + +One asymmetry worth stating: telemetry is computed BEFORE elision and spine +reduction, so the token and turn counts describe the whole transcript while +`elided_blocks`, `elided_bytes` and `omitted_turns` describe the artefact. + +### Surfaces + +`abcd history reconstruct `, exactly one argument. `--out` (default +`.`, `-` for stdout), `--mode` (`full` | `spine`, default `full`), +`--max-block-bytes` (default 8192, 0 disables). Both files are written +atomically into an `--out` that must already exist — the directory is never +created — together or not at all. On stdout the artefact passes through the +terminal-safety filter first, because it is stored transcript text, and the +telemetry follows it in a fenced JSON block so a reader piping to a file still +gets both. The `--json` envelope carries the `Reconstruction` plus either the +written paths or the artefact string, never both. + +The verb carries its section in `commands/history.md`, its row in the brief's +history chapter sub-verb table, and a regenerated surface snapshot and command +reference. + +## How the Acceptance Criteria are satisfied + +- **ac-1 (one artefact; each sub-agent attributable to its spawn point).** One + Markdown document holding the main thread and every stored sub-agent, with the + spawn/join markers, the per-agent provenance block and the timeline table + carrying the attribution, and the unplaceable segregated.

The workaround already in the store answers the first two -by concatenating them into `session_id`, in the shape -`--agent-`. That fails in both directions. -A reader holding the identifier the harness actually gives them (the full -session id) cannot find the record, because the stored value is a truncation of -it; and a reader holding the record cannot recover the full parent id from it, -because the truncation is lossy. Overloading one field with two identifiers is -the defect, so the fix is fields. - -`Record` gains, all optional and all empty on a main-thread record: - -- `agent_id`: the sub-agent's own identifier, as the harness reports it. -- `parent_agent_id`: the identifier of the agent that spawned it, empty when the - main thread spawned it. -- `agent_type`: the kind of agent, as the harness reports it. -- `spawn_depth`: 0 for the main thread, 1 for a sub-agent of it, and so on. -- `spawn_tool_use_id`: the identifier of the tool call in the spawning - transcript that launched this agent, when it can be established. -- `lineage_source`: `hook`, `ingest` or `migrated`, so an empty `agent_type` on - a sub-agent record is distinguishable from an agent type that was never - recoverable. - -`session_id` keeps its existing meaning unchanged: the session the transcript -belongs to. On a sub-agent record it holds the full, untruncated id of the -spawning session, which is what the `SubagentStop` payload delivers. - -`source_kind` is deliberately NOT extended with a sub-agent value. Kind says -where the bytes came from (`native`, `specstory-import`), not what produced -them; encoding agent-ness there would repeat the overloading this section -removes. - -`recordSchemaVersion` moves to 2. A schema-1 record parses as a main-thread -record with empty lineage, so `List` and `Read` keep working over everything -already stored, and the composite records stay readable until `migrate` runs. - -Three consequential changes follow: - -- **The idempotency key becomes `(source_sha256, session_id, agent_id, kind)`.** - Without `agent_id`, two sub-agents of one session that happened to produce - byte-identical transcripts would collapse into one record, which is the - precise failure the existing key's session component was added to prevent. -- **`recordFilename` becomes `-.md` for a main-thread record - and `--agent-.md` for a sub-agent's.** The - filename is readable convenience only. `listRecords` parses frontmatter and - never the filename, so nothing decodes this string back into fields. -- **`Capture` takes a metadata struct.** `Capture(repoRoot, rootSHA string, raw - []byte, meta CaptureMeta)` replaces the five-positional signature; - `CaptureMeta` carries the session id, the six lineage fields and the kind. Six - more positional string arguments on a security-critical call is a - transposition waiting to happen. - -`Read` resolves its key in three steps: an exact record filename, then an exact -`agent_id`, then a `session_id` (preferring the main-thread record, newest -first). A new `ListForSession(rootSHA, sessionID)` returns the whole set for one -session, main thread first, and is what `history show` uses to list a session's -sub-agents under the record it rendered. - -### The frontmatter is redacted with the body - -Every new field is externally supplied: an agent type comes from the harness -payload, an adopted project name from a configuration file a contributor can -edit. `marshalRecord` writes frontmatter, and frontmatter has never been -scanned, so adding externally-supplied scalars to it would open a redaction -bypass beside a redaction gate. - -The fix is not a second scan. `Capture` prepends the lineage scalars to the raw -text as ordinary lines before the existing two-stage pass runs, then splits them -back off afterwards. The scalars therefore go through exactly the same -sanitise-then-verify discipline as the body, including the caller-home backstop -and the fail-closed residual refusal, with no second code path to drift. A -scalar whose redaction changed it is stored changed; a blocking residual refuses -the whole write as it does today. - -### The deferred decision record - -The move from a composite identifier to explicit lineage fields refines -adr-29 and deserves an ADR. It is deliberately deferred and unminted here: the -shape above is the first thing implementation can falsify, and a decision record -minted before its own migration has run would record a decision that has never -met the store. The ADR is minted after this work merges, and until then **this -spec is the decision of record**. - -One caveat for whoever mints it. The repository's root `AGENTS.md` says ADRs are -the one record family whose ids are hand-numbered and so need coordination -between checkouts; the ADR store's own charter records the ruling of 2026-09-01 -that `abcd decide` mints an ADR through the same collision-proof timestamp-numeric -seam as every other family, with the pre-existing ordinals grandfathered. Those -two statements disagree, and the disagreement is not this spec's to settle. -Resolve it before minting, and correct whichever surface is stale. - -### `hook subagent-stop`, and its wiring - -A new operator-internal verb, `abcd hook subagent-stop`, built to the same shape -as `hook session-end`: fail-closed, always exit 0, diagnostics on stderr, -stdout empty. It reads the hook payload from stdin and uses five of its fields: - -- `agent_transcript_path`: the finished sub-agent's own transcript. This is the - whole reason the gap can be closed without reading the harness's on-disk - layout, and its absence is the fallback case below. -- `agent_id`, `agent_type`: the lineage the payload carries directly. -- `session_id`: the spawning session, stored untruncated. -- `cwd`: resolved to the repository's root-commit SHA through `ahoy.Detect`, - exactly as `hook session-end` does. - -It **stages, it does not capture**, for the reason staging exists: redaction runs -at roughly 0.7 s per megabyte, and `SubagentStop` fires inside a live session -where a stall is felt directly. The next `SessionStart` drains it through the -unchanged `Capture`. - -`parent_agent_id` and `spawn_depth` are not in the payload. They are resolved -down a three-rung ladder, and the rung that answered is recorded: - -1. **The harness's own sidecar**, derived from the payload's transcript path by - substituting the extension, never by walking a directory. When it is present - it carries the spawning agent, the spawn depth and the tool-call identifier - that launched the agent. The read is guarded and best-effort: absence, - unreadability, or a mismatched agent id all leave the fields empty and are - never an error. -2. **The spawning transcript's own tool result** for asynchronously launched - agents, which names the agent id beside the tool-call id. Resolved at - reconstruction time, not in the hook. -3. **Unattributed.** The record stores the sub-agent with empty spawn fields, - and reconstruction lists it in a separate, labelled section rather than - guessing a spawn point. - -Wiring: `hooks/hooks.json` gains a `SubagentStop` entry running -`"$CLAUDE_PLUGIN_ROOT/abcd" hook subagent-stop`, using the same binary -resolution preamble as the existing `SessionEnd` entry, and -`applyHookPlaneFailOpen`'s path list gains `{"hook", "subagent-stop"}` so a -usage error on this verb fails open like every other hook path. Without both, -the verb is dead scaffolding. - -### Staging carries a sidecar - -Staged files are currently identified by parsing their filename, which is why -the filename had to encode the session. Encoding lineage there would rebuild the -composite-identifier defect one directory earlier. - -So `Stage` gains a sidecar. It writes two files, both mode 0o600: - -- `-.raw`, the raw bytes, where `` is the agent id when there - is one and the session id otherwise. -- `-.stage.json`, holding a schema version, the session id, the six - lineage fields, the source path the bytes were read from, and the stage time. - -`listStaged` reads the sidecar when it is present. A `.raw` file with no sidecar -is a staged file from an older binary: its session id is parsed from the -filename exactly as today and it drains as a main-thread transcript, so an -upgrade never strands a backlog. - -Stage idempotency moves from the session id to the `(session_id, agent_id)` pair, -with the existing content compare and the existing last-writer-wins replacement, -all still inside the staging lock. - -### The drain's order and its budget - -Two changes, both forced by the volume this intent admits. - -**Order.** `listStaged` is chronological, and a session's main thread is staged -last because it ends last, so a bounded pass would drain the branches and leave -the spine. The drain therefore takes main-thread entries first, then sub-agent -entries oldest-first. If a pass is truncated, what it stored is the part that -makes the rest legible. - -**Budget.** `sessionStartDrainBudget` becomes a pair: a byte bound and a count -bound, whichever is reached first. The byte bound is the one that protects the -first prompt, because redaction cost tracks bytes rather than files, and the -count bound keeps a pathological many-tiny-files case bounded too. A session -that delegates heavily can stage dozens of transcripts, and a count-only budget -of four would leave the rest unredacted at 0o700 for as many sessions as it -takes to work through them. The remainder is reported as it is today, and the -`SessionStart` notice gains a sentence naming how many staged transcripts are -still unredacted, because a growing pile of raw text is a privacy fact and not a -scheduling detail. - -### `history ingest`: the destination is an operand - -`Ingest` is the recovery path for transcripts that are on disk and were never -captured. Its signature makes the destination explicit and non-derivable: - -``` -history.Ingest(dest Destination, sources []string, opts IngestOptions) (IngestResult, error) -``` - -`Destination` carries the repository root and its root-commit SHA. The scanner -is constructed from `dest.RepoRoot` and from nothing else, so a repository's own -`pii.json` and `gitleaks.json` govern its own transcripts and can never be -applied to another repository's. This is the seam the intent requires, and it is -a seam rather than a default because the working directory is exactly the wrong -authority here: an operator recovering a backlog is not standing in the -repository the transcripts belong to. - -`sources` are explicit file or directory paths. There is no implicit "scan the -harness's store" mode: a vendor path baked into core would be the on-disk-layout -dependency the intent's mechanism rules out. A repository that ingests regularly -declares its roots in `.abcd/config/history.json` so the operator does not -retype them, and the configuration is the only place a path lives. Directory -sources are walked for line-delimited transcripts to a bounded depth; every read -is guarded and capped exactly as the hook path's read is. - -`IngestResult` reports four populations: `captured`, `skipped` (each with a -reason), `orphans`, and `failed`. Nothing is silent. - -### Resolving the owning repository - -Per transcript, in order: - -1. Collect the distinct `cwd` values recorded on the transcript's own lines, - reading a bounded prefix plus the final line rather than the whole file. -2. Resolve each through `ahoy.Detect` to a root-commit SHA. A session run in a - worktree resolves to the repository the worktree derives from, because they - share a root commit, which is the scope condition the intent already records. -3. One root SHA, equal to `dest.RootSHA`: ingest it. -4. One root SHA, different: skip with reason `owned-elsewhere`, reporting the - root SHA. A SHA names a repository without naming it. -5. Two or more distinct root SHAs: skip with reason `ambiguous-owner`. A - transcript is never split between stores. -6. No resolvable `cwd`, or a `cwd` that no longer exists on disk: an orphan, - handled below. - -The harness's project-directory name is never decoded. It is not reversible to a -filesystem path (a directory named for a repository and a path with a separator -in the same position produce the same mangled name), so the recorded `cwd` is -the only sound signal, and it is the one this uses. - -### Orphans are ignored, reported, and adopted only by name - -The default for a transcript whose repository cannot be found on disk is to -**ignore it and say so**. It is listed in `orphans` with its project directory -name as given and its recorded working directory home-redacted, and nothing is -written. - -Adoption is opt-in and per repository, declared in `.abcd/config/history.json`: - -```json -{ - "schema_version": 1, - "ingest_roots": [], - "adopt_projects": [], - "on_orphan": "ignore" -} -``` - -`adopt_projects` lists the project directory names this repository claims. A -transcript under a claimed name is ingested into this repository's store, under -this repository's redaction configuration, and its record is stamped -`lineage_source: ingest` together with `adopted_project`, so the adoption is -recorded on the artefact rather than only in a run's output. - -`on_orphan` accepts `ignore` (the default) or `prompt`. Core never prompts: -under `prompt` it still ingests nothing and returns the orphan list, and the CLI -front door is what asks the operator and re-invokes ingest with the chosen names -in `opts.Adopt`. The transport-agnostic boundary is not negotiable, and an -interactive question is a transport concern. - -Configuration is loaded by `history.LoadConfig(repoRoot)` under the same -discipline the scanner's per-repo configuration already uses: a size cap, a -symlink refusal, and containment inside the repository. - -### `history migrate`: the composite records - -The records already written under composite identifiers are the migration's -input. The count is per-machine local data rather than a fixture; the store this -was designed against held 176 of them. - -`Migrate(rootSHA string, apply bool)` walks the store for a `session_id` matching -`^--agent-$` and, for each: - -- takes `agent_id` from the suffix; -- **repairs the truncated parent id from the record's own body**, which still - carries the full session identifier on its transcript lines, and requires the - recovered value to begin with the stored prefix. A body that disagrees, or one - where no session identifier can be found, leaves the record untouched and is - reported. The truncation is lossy, so the prefix is a check and never a source; -- leaves `agent_type`, `parent_agent_id` and `spawn_depth` empty, since neither - the record nor the store ever held them, and stamps - `lineage_source: migrated` so the emptiness reads as unrecoverable rather than - as a main-thread record; -- rewrites the frontmatter atomically and does not touch the body. - -Three properties matter. `source_sha256` is computed over the raw source and is -not recomputed, so a migrated record still dedups against a re-capture of the -same bytes. The filename is left alone: a rename would break any path a reader -already holds and buys nothing, because listing reads frontmatter. And the verb -**reports by default and writes only under `--apply`**, because the store holds -the only copy of these records. Re-running it is a no-op: a record that already -carries `agent_id` is skipped. - -### `history reconstruct`: one artefact and one telemetry file - -`Reconstruct(rootSHA, sessionID string) (Reconstruction, error)` returns the -artefact bytes and the telemetry structure. Core writes nothing; the CLI writes -the two files into `--out` (default the current directory) or to stdout for `-`. - -The artefact is **Markdown**, named `.md`. The requirement is that -it be handed to a model as context and read without the store or the harness's -files, and Markdown is what a model reads without a schema. Its shape: - -- A header block: schema version, session id, root commit, span, record count, - agent count, and a completeness block saying what was missing. -- `## Main thread`, rendered turn by turn. -- At each spawn point, an inline marker naming the agent type, the agent id and - the time, immediately before the nested section it introduces. -- `## Sub-agent ` sections, nested by `spawn_depth`, each stating who - spawned it, at which point, and over what span. A sub-agent that spawned - sub-agents nests again, to whatever depth the records carry. -- `## Unattributed sub-agents`, last, for anything the attribution ladder could - not place. Labelled, never interleaved. - -Concurrency is represented rather than linearised, which answers the intent's -open question. Sub-agents are ordered by their spawn point in the spawning -transcript, not by their own timestamps; several spawned in one turn are -rendered in the order their spawn points appear in that turn, and the section -says in words that they overlapped, with each carrying its own start and end. -Nothing in the artefact implies that a later section began after an earlier one -ended. - -The artefact is self-contained by construction and by test: it carries no store -path, no harness path and no absolute path of any kind. - -The telemetry file is `.telemetry.json`: - -- `schema_version`, `session_id`, `root_commit` -- `started_at`, `ended_at`, `wall_clock_seconds` -- `turns`: user, assistant, total -- `tokens`: input, output, cache creation input, cache read input -- `tool_calls`: a count per tool name -- `models`: the distinct model identifiers seen -- `agent_types`: the distinct agent types seen -- `agents`: one entry per agent (the main thread included) carrying its id, - parent, type, spawn depth, model, span, turns, tokens and tool-call counts -- `completeness`: records present, sub-agents unattributed, and the named fields - that were absent from the source lines - -`completeness` is not decoration. The intent's scope condition says telemetry -describes what the harness recorded and is not a billing record, and a derived -measure that cannot say what it was missing invites exactly the comparison -across harness versions the condition warns against. - -### Failure modes - -- **The event fires before the transcript is flushed.** The likeliest way this - design is shown wrong, and the first thing implementation measures. Two - mitigations, both cheap. At stage time, a transcript whose final line is not - complete JSON is re-read after a short bounded wait, up to a small fixed - number of attempts. At drain time, the source path recorded in the staging - sidecar is re-read when it still exists, and its bytes replace the staged copy - only when they are strictly longer AND the staged bytes are a prefix of them, - so a recycled path can never substitute a different transcript. Truncation - that survives both is a shorter record, not a corrupt one, and the residual - rate is what the measurement reports. -- **A session with many sub-agents.** Staging is one write per completion, so - the hook's cost is independent of the count. The drain is where the count - lands, which the byte-and-count budget and the drain ordering above address. - The failure this leaves is a backlog of unredacted staged text, which is - reported by `history staged` and named in the `SessionStart` notice. -- **The payload is absent on an older harness.** No `agent_transcript_path` - means the hook warns on stderr, stages nothing and exits 0. Silence is what - this intent exists to end, so the hook also drops a marker beside the staging - directory the first time it sees a payload without the field, and - `history staged` reports it: this harness version does not deliver sub-agent - transcripts, so no sub-agent capture is happening here. -- **An unreadable transcript.** The existing guarded read already refuses a - symlink, a FIFO, a device node, a non-regular file and an over-cap file, and - refuses an over-cap file whole rather than truncating it. Reported on stderr, - nothing staged, exit 0. -- **A degraded scanner.** Unchanged and untouched. Sub-agent capture runs - through the same `Capture`, so the refusal on a degraded scanner or a surviving - blocking span applies by construction; the tests assert it on the sub-agent - path specifically rather than inferring it. - -### Surfaces - -Three new user-facing sub-verbs (`ingest`, `reconstruct`, `migrate`) and one new -operator-internal hook verb. Each needs, in the same change: - -- The `history` sub-tree moved out of `internal/surface/cli/cli.go` into - `internal/surface/cli/history.go` as a pure move with no behaviour change, - before the new verbs are added, so they land in a file that is about one thing. -- Sections in `commands/history.md`, which is the plugin surface for a user verb. - The hook verb's plugin surface is its `hooks/hooks.json` entry, as it is for - `hook session-end`. -- Rows in the brief's history chapter sub-verb table, which `surface_coverage` - checks in both directions and refuses on. -- A regenerated surface snapshot (`cmd/abcd-gen-surface`) and a regenerated - command reference (`cmd/abcd-gen-cli-ref`). - -### Landing order - -Each step leaves the tree green, and each has its own tests. - -1. **The record schema.** Schema version 2, the six fields, `CaptureMeta`, the - widened idempotency key, the frontmatter-through-the-redaction-pass change, - `Read`'s three-step resolution and `ListForSession`. Existing callers updated; - no new verb yet. -2. **Staging's sidecar.** `.stage.json`, the `(session, agent)` idempotency key, - the legacy sidecar-less path, the drain's main-thread-first ordering and the - byte-and-count budget. -3. **The hook.** `abcd hook subagent-stop`, its `hooks.json` entry, its - fail-open path registration, the harness-sidecar rung and the missing-payload - marker. This is the point at which the corpus starts accruing, so it lands - before the recovery verbs. -4. **The measurement.** An instrumented run over real sessions counting how many - staged sub-agent transcripts arrive truncated. If the rate is not near zero, - revisit step 3's mitigations before continuing; the number goes into the - intent's grounds either way. -5. **`history migrate`.** Report mode, then `--apply`, run against the real store - once the tests pass. -6. **`history ingest`.** The destination seam, the owning-repo resolution, the - configuration file, and the orphan policy with its front-door prompt. -7. **`history reconstruct`.** The artefact, then the telemetry file, then the - attribution ladder's second rung. -8. **The surfaces.** The CLI file move happens at the top of step 6; the plugin - page, the brief rows, the surface snapshot and the command reference are - regenerated once, here, and the docs-currency and surface-coverage gates are - what prove it. - -## How the Acceptance Criteria are satisfied - -The intent's criteria in order. - -- **ac-1 (a sub-agent's transcript is stored, redacted, and listed).** The - `SubagentStop` hook stages it; the next drain captures it through the unchanged - fail-closed `Capture`; `List` returns it. Test: - `TestSubagentStopStagesAndDrainStores` drives the verb with a payload and - asserts a record with the lineage fields set. -- **ac-2 (nesting, each attributable to its spawner).** `parent_agent_id` and - `spawn_depth` come from the attribution ladder and are stored per record. Test: - `TestNestedSubagentsAreBothStoredAndAttributed` stages a depth-1 and a depth-2 - agent and asserts the parent chain resolves. -- **ac-3 (found from the spawning session's identifier, with its kind).** - `session_id` holds the untruncated spawning session, so `ListForSession` - returns the main thread and every sub-agent, each carrying `agent_type`. Test: - `TestListForSessionReturnsMainThreadAndEverySubagent`. -- **ac-4 (a degraded scanner refuses).** Unchanged `Capture`. Test: - `TestSubagentCaptureRefusesDegradedScanner` runs the sub-agent path with a - broken per-repo configuration and asserts no record was written. -- **ac-5 (the same transcript twice is a no-op).** The widened idempotency key. - Tests: `TestSubagentCaptureIdempotentOnSourceSHA` and - `TestTwoSubagentsWithIdenticalBytesBothStore`, the second bounding the first so - the key cannot be over-tightened back into the collapsing bug. -- **ac-6 (a completion without a readable transcript is reported, not silent and - not fatal).** The hook's warn-and-exit-0 paths plus the missing-payload marker. - Test: `TestSubagentStopNeverBlocksTheHost`, a table over an absent path, a - FIFO, a symlink, an over-cap file, a malformed payload and a payload with no - `agent_transcript_path`, each asserting exit 0, zero records, and a non-empty - stderr reason. -- **ac-7 (ingest under a repository's own configuration, twice adds nothing).** - `Ingest`'s explicit destination and the unchanged idempotency. Tests: - `TestIngestUsesTheDestinationReposRedactionConfig` (two fixture repositories - with different rules, asserting the destination's applied and the source's - not) and `TestIngestTwiceIsANoOp`. -- **ac-8 (an unidentifiable repository is skipped and reported).** The resolution - ladder's steps 4, 5 and 6. Tests: `TestIngestSkipsATranscriptOwnedElsewhere`, - `TestIngestSkipsAnAmbiguousOwner`, `TestIngestReportsAnOrphanAndWritesNothing`. -- **ac-9 (a configured adoption stores and records it).** `adopt_projects` plus - the `adopted_project` stamp. Test: `TestIngestAdoptsAConfiguredOrphanProject` - asserts the record exists in the destination store and carries the stamp; - `TestIngestDoesNotAdoptWithoutConfiguration` is its negative control. -- **ac-10 (one artefact, each sub-agent attributable to its spawn point).** - `Reconstruct`'s nested rendering and its unattributed section. Tests: - `TestReconstructNestsEverySubagentAtItsSpawnPoint` and - `TestReconstructSegregatesUnattributedSubagents`. -- **ac-11 (a machine-readable telemetry file with the named measures).** The - telemetry structure. Test: `TestTelemetryReportsEveryRequiredMeasure` asserts - each named field is present and non-trivial over a fixture session, and - `TestTelemetryReportsItsOwnIncompleteness` asserts the completeness block names - a field the fixture deliberately omits. -- **ac-12 (readable without the store or the harness's files).** Test: - `TestReconstructionIsSelfContained` asserts the artefact contains no absolute - path, no store root and no reference resolvable only against the harness. - -## Tests - -`internal/core/history`: the schema round-trip over both versions -(`TestSchemaOneRecordReadsAsMainThread`), the frontmatter redaction -(`TestLineageFieldsAreRedactedWithTheBody`, -`TestBlockingSpanInAgentTypeRefusesTheWrite`), the idempotency pair above, -`Read`'s resolution order (`TestReadResolvesFilenameThenAgentThenSession`), -staging's sidecar and its legacy path (`TestStagedFileWithoutSidecarStillDrains`), -the drain's ordering and budget (`TestDrainTakesMainThreadFirst`, -`TestDrainStopsOnWhicheverBudgetBindsFirst`), migration -(`TestMigrateRepairsTheTruncatedParentFromTheBody`, -`TestMigrateLeavesARecordWhoseBodyDisagrees`, `TestMigrateIsIdempotent`, -`TestMigrateWritesNothingWithoutApply`), ingest's five resolution outcomes, -configuration loading (`TestHistoryConfigRefusesASymlink`, -`TestHistoryConfigDefaultsToIgnoringOrphans`), and reconstruction with its -telemetry. - -`internal/surface/cli`: the hook table above, `TestSubagentStopWritesNothingToStdout`, -`TestHookPlaneFailsOpenOnEveryUsageError` (existing, extended by the manifest to -cover the new path), the three new verbs' rendering and `--json` envelopes, and -`TestIngestPromptNeverReachesCore` asserting that core returns orphans and -ingests none of them whatever `on_orphan` says. - -Gates: `surface_coverage` over the new sub-verbs, the regenerated snapshot and -command reference, and `make record-lint` over this spec and the intent. - -## Uncertainties - -Three, stated rather than smoothed over. - -- **Whether `SubagentStop` fires after the sub-agent's transcript is flushed** is - not established.

The - payload carries the agent id and the agent type, so ac-3 holds regardless; what - degrades without it is the spawn point, and therefore the precision of ac-10's - nesting rather than its existence. -- **The ADR ordinal question flagged above.** Two committed surfaces disagree - about how an ADR id is allocated. That does not block this spec, but it blocks - minting the ADR this spec defers. - -## Out of scope - -Redesigning the store's keying or provisioning.

The drain builds its scanner from the destination repository's root, because that repository's own redaction configuration must govern its own transcripts. When the repository's directory is gone, that root cannot be resolved and the drain has nothing to run with, so the raw bytes stay staged forever with no path to redaction. This is not hypothetical: one store on this machine holds 11.7 megabytes of unredacted staged text whose repository was deleted, which is the largest single pile in the store and the only one that no amount of ordinary use will clear. The retention work just landed addresses the case where nobody opens a repository again, by draining while a session is live and by reporting other repositories' backlogs at session start, but both remedies assume the repository still exists to be opened. The options are to let a deletion of the repository be a trigger that drains or discards first, to allow a drain under an explicitly named substitute configuration with the substitution recorded on the record, or to treat the pile as terminal and offer only discard. Whichever is chosen, the present behaviour is the worst of them: the text is kept, unredacted, with no way to act on it and nothing saying so. diff --git a/.abcd/work/issues/open/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md b/.abcd/work/issues/resolved/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md similarity index 65% rename from .abcd/work/issues/open/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md rename to .abcd/work/issues/resolved/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md index 5c1b152c..8598357b 100644 --- a/.abcd/work/issues/open/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md +++ b/.abcd/work/issues/resolved/iss-2609081917287384-the-transcript-store-captures-only-the-top-level-session-tra.md @@ -10,6 +10,11 @@ origin: researcher-authored production_mode: hand-written found_at: "internal/surface/cli/cli.go" promoted_to: itd-2609090559376002 +resolution: "Sub-agent transcripts are captured through the harness's completion event into the same redact-on-write store the main thread already used, with lineage carried in explicit record fields rather than an overloaded identifier.

Storing the result needs a lineage decision the Record schema cannot currently express: it has no parent, agent or type field, and source_kind is closed to native and specstory-import, so the only representable form is overloading session_id with a composite.

Those links resolve to nothing the moment the move completes, and the record gate refuses on them, so a close that reports success hands the next command a tree that will not lint. Three closes in one sitting produced eight dead links here and a red preflight immediately afterwards, with nothing in the close output hinting at it. The verb already knows both the old and the new path, so it is the one thing in the system positioned to fix or at least name them. Either rewrite links to the moved record in the same operation, or refuse the close while a link in the spec names the folder the intent is about to leave, or say at minimum which links the move has just invalidated. Silence is the worst of the three, because the failure surfaces later, in a different command, as a lint error that looks unrelated to the close that caused it.

A tool call's name, its identifier, a tool result's identifier and a turn's model name were formatted straight into the document outside any fence, with no guard but a helper that substitutes a dash for the empty string. A line break in any of them emitted lines of the document itself, and the shapes it could emit were an agent section heading, a turn heading and a join marker: exactly what the earlier fix was meant to make unforgeable. Its regression test planted the payload only in a text block, which is why this passed. The sweep found nine sites, not the four the finding named. Two more are transcript-controlled: an unknown block's type, and the tool-call identifier the spawn point is recovered from when placement came from the transcript rather than the record. The rest are record-derived, where a line break cannot survive the frontmatter parser but a backtick or a pipe can, and a pipe in the timeline shifts every later cell so the table reports spans against the wrong agents, which is a false claim rather than a cosmetic one. Sites that were already safe were routed through the same cleaner anyway. A per-site judgement about which values are dangerous is precisely what let this gap open, and the fix that keeps a judgement keeps the gap. The cleaner is the repository's existing canonical one-line cleaner rather than a fourth copy of an escaping rule; the surface layer's own sanitiser does not fit, because core cannot import it and its semantics are to drop the whole value, which is right for a record write and destructive for a label. The guide the artefact hands its reader stated a rule the renderer did not hold. It now states the one that ships, and it no longer asks the reader to classify anything: every line of this document begins with words the document chose, and nothing quoted from the session can begin one.

Concern, and it is a `wired or it isn't done` concern: no operator surface in THIS delivered range consumes ListForSession — its only non-test caller is reconstruct.go, delivered by the excluded commit 9af9a30a — `history show ` deliberately returns the main-thread record ALONE, and the human render of `history list` and `history show` prints no agent_id and no agent_type. The operator's only route is `abcd history list --json` plus hand filtering on session_id, which the plugin page's documented field list does not mention.

Concern: NOTHING tests it. A grep for the refusal string or for Unavailable across internal/core/history's tests returns nothing — not on the sub-agent path and not on the session path — so the spec's claim that `the tests assert it on the sub-agent path specifically rather than inferring it` is false; the four tests it names cover lineage redaction, a blocking residual and a malformed scalar, none of which degrades the scanner.

The bounding case is held too — two sub-agents of one session with byte-identical transcripts still store two records.

Ingest refuses an empty root and shape-checks the key, and then trusts that the two describe the same repository. A caller passing a mismatched pair would redact a transcript under one repository's configuration and file it into another's corpus, which is exactly the fault the explicit-destination design was introduced to make impossible.

But the show verb deliberately returns the main-thread record alone, the human render of list and show prints neither the agent identifier nor the agent type, and the only caller of the session listing outside the tests is the reconstruction path. The operator's actual route is therefore to take the machine-readable listing and filter it by hand on the session field, which works because the envelope marshals the whole record, but it is not documented on the surface page's field list and it is not what the acceptance criterion describes a person doing. By this repository's own rule that a capability is not delivered until it is reachable from both front doors, this is the first gap to close: either the human render carries the lineage columns and show grows a way to ask for a session's whole set, or the surface page documents the JSON route explicitly.

A transcript carrying a line break inside any of those fields therefore emits lines of the document itself, and the lines it can emit include an agent section heading, a turn heading and a join marker, which are exactly the shapes the earlier fix set out to make unforgeable. The regression test plants its payload only in a text block, so nothing exercises the metadata path and the gap passed unnoticed. The consequence falls on the reader the artefact is written for: the guide it carries tells that reader everything inside a fence is something somebody said and everything outside one is the document, and that is not the rule the renderer implements. The fix is to sanitise every scalar interpolated outside a fence rather than to fence more, since these are single-line labels, and to extend the regression test to each of them. Until then the document states a guarantee it does not hold, which is worse than stating none. + +## Grounds + +- pursued: we expect containment to be the whole answer here, because these are single-line labels whose only power is to leave their line, so stripping the line break removes the forgery and escaping the backtick and pipe removes the quieter falsehoods of escaping a code span and shifting a table's cells; it is shown wrong if a value can forge a line by some route that is not a line break, or if the cleaner's own rewrites make a label misrepresent what the session actually contained diff --git a/internal/core/history/reconstruct_render.go b/internal/core/history/reconstruct_render.go index c339d3e0..1d9db10a 100644 --- a/internal/core/history/reconstruct_render.go +++ b/internal/core/history/reconstruct_render.go @@ -16,6 +16,8 @@ import ( "fmt" "strings" "time" + + "github.com/intentdriven/abcd/internal/termsafe" ) // stamp is the timestamp format used everywhere in the artefact: second @@ -111,14 +113,14 @@ func (s *session) render() []byte { // telemetry, where a changing value costs nothing. func (s *session) renderHeader(b *strings.Builder) { tel := s.telemetry - fmt.Fprintf(b, "# Session %s\n\n", s.opts.SessionID) + fmt.Fprintf(b, "# Session %s\n\n", safeInline(s.opts.SessionID)) b.WriteString("One session, reconstructed from abcd's transcript store: the main thread and " + "every sub-agent transcript stored for it, in one self-contained document.\n\n") fmt.Fprintf(b, "- reconstruction schema: %d\n", reconstructSchemaVersion) - fmt.Fprintf(b, "- session: `%s`\n", s.opts.SessionID) - fmt.Fprintf(b, "- root commit: `%s`\n", s.rootSHA) - fmt.Fprintf(b, "- mode: %s\n", s.opts.Mode) + fmt.Fprintf(b, "- session: %s\n", inlineCode(s.opts.SessionID)) + fmt.Fprintf(b, "- root commit: %s\n", inlineCode(s.rootSHA)) + fmt.Fprintf(b, "- mode: %s\n", safeInline(string(s.opts.Mode))) fmt.Fprintf(b, "- main thread: %s\n", presentAbsent(s.main != nil)) fmt.Fprintf(b, "- agents: %d (%d sub-agent transcript(s) besides the main thread)\n", len(s.threads), len(s.subs)) @@ -128,7 +130,7 @@ func (s *session) renderHeader(b *strings.Builder) { fmt.Fprintf(b, "- turns: %d (%d user, %d assistant)\n", tel.Turns.Total, tel.Turns.User, tel.Turns.Assistant) fmt.Fprintf(b, "- tokens: %d over %d API response(s)\n", tel.Tokens.Total, tel.Tokens.APIResponses) - fmt.Fprintf(b, "- telemetry: `%s`\n", s.opts.SessionID+telemetrySuffix) + fmt.Fprintf(b, "- telemetry: %s\n", inlineCode(s.opts.SessionID+telemetrySuffix)) b.WriteString("\n## How to read this document\n\n") b.WriteString("1.

Their run was treated as a field experiment on abcd's gaps: what does an autonomous operator need that abcd does not give it. This is what they found, recorded here so it can be assessed rather than lost with their sessions. Thirteen of these had already been written as properly formed records into a handoff directory in that repository, over two days, and none had ever reached this ledger. The channel exists and nothing drains it, which is itself the first finding about the arrangement. The synthesis is the most valuable single item and has its own record: the record verbs are sound, and the failures were all at the edges, where the tool knows something and does not say it. It holds the enum it is validating against and names only the offending value; it had the closing commit in hand when it minted a receipt and did not write it down; it names the file it wants without saying how to make one. That is a testable claim about where to look, not a complaint, and it earns a record rather than a footnote. Two findings were corroborated by more than one session independently, which is evidence about likelihood rather than possibility: an unknown sub-verb minting a draft intent from its own name, and required flags being learned from a refusal rather than from help. Two more were appended to existing records that had already predicted them rather than filed again. One record is positive and kept deliberately: every record verb worked from worktrees across 27 branches, and the ledger's one-file-per-record shape produced no merge conflict in the whole run. What held is evidence in an experiment, not filler.

The plugin surface is told to relay the count, so a caller can say "one span was rewritten" and still not know what changed. A count is not a diff. Finding the corruption required grepping the written record and comparing it to the input by eye. + +The collision class is large and ordinary, not exotic. Reverse-DNS identifiers begin with a small set of short words: `com`, `io`, `app`, `net`, `org`, `me`, `sh`, and the usual three-letter abbreviation for development. Every one of them is a plausible Unix account name. Any repo whose maintainer's account name is one of those words cannot write its own bundle identifier, module path, package name or domain into a capture without it being mangled. The likelihood is not the maintainer being careless; it is two very short common words coinciding. + +It corrupts rather than refuses. Everywhere else abcd fails closed and says so: a malformed banlist line refuses the commit, an unreadable identity pin blocks, a missing docs root refuses the lint rather than passing.

Report what was redacted, not how many: the JSON should carry each span's rule and its position so a caller can show the user the change and undo it. Do not match a bare account name inside a dotted identifier; a token bounded by dots on both sides, or followed by a dot and a known TLD-shaped component, is a namespace, not a home directory, and the existing rule already knows how to recognise a path, which is the shape that actually leaks. Offer an opt-out for a span the author asserts is safe, the way `abcd-lint:allow` works for the privacy rule, so a maintainer whose account name is a reverse-DNS prefix can still write their own identifier. + +Related: the `privacy-hygiene` lint rule flags persona-derived paths the conventions mandate, filed separately.

A later run of the same repository's lint reported between 147 and 213 privacy errors, all of the same two classes. + +What was actually flagged: persona home paths under the three names the conventions themselves mandate (Alice, Bob, Carol) in test fixtures and documentation, plus the group-readable shared-directory root the product creates and therefore has to name in its own comments, tests and install docs, plus a set of classifier fixtures. No real username appears anywhere in the tree; the only home directories committed are the personas the conventions ask for. + +Why this is worse than noise. The rule's own fix hint already blesses persona material: it says to replace a network identifier with "a reserved documentation value (RFC 5737/3849/2606/7042, or a persona-derived device name)". So personas are understood to be the safe form for one identifier class and not for the other, with no stated reason. The result is dozens of errors a maintainer must learn to ignore, which is exactly how a real leak gets waved through later: the rule that cries wolf on a persona home path is the rule nobody reads when it finally names a real one. It also puts the lint permanently red on a repo that is, on this rule, clean. + +The cost is measurable in the autonomous run this was observed in. Every worker had to be told in its launch prompt to ignore the privacy count, and two of them stopped and asked whether they had broken something. A detector that is red at baseline is a detector nobody reads, and a per-worker instruction to ignore a specific gate is a standing invitation to ignore the next one. + +Needed: teach `privacy-hygiene` the persona names the conventions already fix, so a path under one of them is not a finding, the same way a persona-derived device name is not. A shared-directory system root is likewise not a personal path and is frequently a real product path that documentation has to state. Failing that, the rule should say in its message that the escape for a deliberately illustrative persona path is `abcd-lint:allow`, and the convention should say that a repo using persona paths is expected to carry that marker on every one.

Then, optionally, a verb (`intent errata`, or an `--errata` mode on the existing audit-notes writer) so the correction is a recorded operation rather than hand-appended prose, and so a reader can tell a correction from a finding.

The constant's own comment says: "Unlike the VERSION location (which version-location.json makes negotiable per adr-19), the manifest's own path is fixed by the harness's discovery rule — a plugin.json anywhere else is not found at all". The reasoning for the fixed PATH is sound: the harness really does discover a plugin manifest at one location only. But it answers a different question from the one that bites. Where the manifest lives and whether the artefact has one are separate facts, and adr-19 already established that a release-shaped fact can be declared per repo rather than assumed. + +So the defect is not that the path is a constant. It is that a MISSING manifest is treated as a broken payload rather than as "this artefact is not a plugin": one unconditional read, sitting next to a sibling problem abcd chose to make negotiable. + +What this costs a non-plugin repo, in the order a maintainer meets it. `launch --dry-run`, `changelog` and `launch ship` all refuse, so the derived changelog never runs; the repo falls back to a hand-written CHANGELOG; and the convention that a user-facing change is accompanied by a RECORD rather than hand-written release prose becomes unenforceable exactly where it was meant to bind.

It is that the agent treated documentation prose as evidence about a running UI. Fetching the vendor's guide felt like verification (it is a primary source, it was quoted accurately) but a doc sentence is evidence of what someone wrote, not of what the page renders today. The agent had the operator's screenshots available from the fourth exchange onward and only then began giving instructions that landed; it also had browser automation tooling in-session and never once offered to look at the page itself. + +The two classes of claim can be scored separately, and the split is not subtle. + +Claims sourced from vendor documentation: four made, four wrong. Two were recalled and described the wrong one of two similar token pages. One was fetched from the vendor's own current guide during the session and quoted exactly; it named a dropdown the page does not have. One, also fetched, named two form fields that do not exist in the current UI at all — the shipped page instead pre-fills two already-scoped policy boxes, and there is nothing to fill in. The operator asked directly, "you asked me to fill out those, where are they?" The third instruction is the instructive one: by every ordinary test it was verified, and it was still wrong about the screen, because the page had been rebuilt and the prose had not. + +Claims sourced from a screenshot: four made, four correct on first attempt. Same agent, same task, minutes apart. 0/4 before, 4/4 after. + +A compounding failure with the same shape. The agent withheld the hosting account id for four exchanges as a "secret value", per a standing instruction that named it as one of the two secrets the operator alone must create. The id was already public in the repository's own pull-request check links, and was visible in the operator's address bar throughout. Every URL the agent gave therefore arrived as a template with a placeholder, which is precisely what made them unusable as instructions. Withholding it protected nothing and cost most of the confusion. The rule's purpose is to keep the agent from handling credentials; an account identifier that grants nothing on its own, that the operator owns, and that is already published, is not the thing the rule is for. A privacy rule applied without reading its purpose degraded the work while protecting nobody. The cost landed as unusable instructions rather than as a visible refusal, so nothing flagged it. + +The finding, stated so it can be tested: fetching a vendor's current documentation is not verification of a vendor's current UI. It is verification of the documentation. The two drift independently and the doc is the slower of the pair, so for any UI that has been redesigned recently the doc is reliably wrong rather than randomly wrong, which makes it worse than no source at all, because it carries the felt authority of a primary source and the agent stops looking. + +Proposed rule for a managed repo. An instruction that navigates a third-party UI carries a verification tag: "seen this session" or "from vendor docs, unverified". Where the operator is already in front of the UI, one screenshot is taken before the SECOND guess, never after the fourth. Where the agent has browser tooling and the operator is logged in, looking at the page is cheaper than three rounds of correction and should be the first move. And a redaction rule needs a stated purpose alongside its pattern, so an agent can tell an identifier from an authenticator; a rule listing a public account id as a secret, with no note of which it is, will keep producing this. + +What would falsify it: if UI-navigation instructions sourced from current vendor docs land, say, four times in five across a handful of vendors, the tag is unnecessary ceremony and should be dropped. The prediction here is the opposite — that redesigned dashboards make doc-sourced navigation fail most of the time, and that the failure is invisible to the agent, which is what makes a tag worth carrying. + +Residue worth keeping: the corrected sequence is now known-good and was established empirically, not from any document. A verified runbook is worth committing precisely because it rots — the value is the date stamp and the screenshots, not the prose — and it should be re-verified rather than trusted on next use. diff --git a/.abcd/work/issues/open/iss-2609100506256636-ahoy-refuses-forever-on-a-symlink-its-own-tests-left-behind.md b/.abcd/work/issues/open/iss-2609100506256636-ahoy-refuses-forever-on-a-symlink-its-own-tests-left-behind.md new file mode 100644 index 00000000..ac9457ad --- /dev/null +++ b/.abcd/work/issues/open/iss-2609100506256636-ahoy-refuses-forever-on-a-symlink-its-own-tests-left-behind.md @@ -0,0 +1,22 @@ +--- +schema_version: 1 +id: "iss-2609100506256636" +slug: "ahoy-refuses-forever-on-a-symlink-its-own-tests-left-behind" +severity: "major" +category: "bug" +source: "user-observation" +found_during: "autonomous-run field experiment in a managed repository, 2026-09-07/08; re-filed into abcd 2026-09-10" +origin: researcher-authored +production_mode: hand-written +found_at: "internal (ahoy install, symlink.foreign)" +--- + +abcd's own test suite leaves a dangling symlink on PATH, and `ahoy install` then refuses to complete for ever, with no supported way to clear it. + +Found at the very start of adopting abcd in a managed repository. `abcd` was not on PATH at all, and the user-level bin entry was a symlink pointing into a deleted temp directory whose name is a Go test name from abcd's own ahoy install suite (a `TestAhoyInstallAccepts…` directory, with the numbered subdirectory a t.TempDir tree leaves behind).

Three were already in the ledger from the earlier sweep and are left as they are. Five are new. One is recorded against what was actually measured rather than what was reported. The corrected one matters most for how these reports are read. The session believed two captures had been silently lost to an exit status of zero. Tested on both the published release and current source, an unknown category is refused with exit status one, the error goes to standard error as JSON, standard output is empty, and no record is written: verified against the ledger and a clean tree. Nothing was lost. What the session saw was a machine-readable invocation producing no machine-readable output, in a pipeline that did not surface the exit status, for a flag whose accepted values are documented nowhere. Those three together read as silent loss, and the report was made in good faith. The finding is recorded as what it is, a shape that makes an operator doubt the store rather than the flag. The sharpest new one came from checking the session's own claim against this repository. It reported writing two invented record ids into a spec and catching them only on re-reading. Nothing gates that. Attempting the check here showed why it is harder than it looks: the decisions family carries two filename conventions, one zero-padded ordinal that differs from the id in its own frontmatter and one timestamp without the prefix the id begins with, so no cited id can be mapped to a file by name at all. Any check has to resolve through frontmatter, which is also why it does not exist yet. Also recorded: an intent can be planned with no impact and only discovers it at spec close, in the landing commit, which two sessions hit independently in a day and both fixed by editing frontmatter because no verb stamps it; the grounds requirement is documented after the step that enforces it; and cross-session claim on worktrees and records is coordinated entirely by conversation, measured at four messages and about fifteen minutes for one session to join work already in progress.

Whatever holds it should be as cheap to write as it is to read, because a coordination record nobody updates is worse than the chat it replaced. diff --git a/.abcd/work/issues/open/iss-2609100519128005-a-refused-capture-writes-its-error-as-json-to-standard-error.md b/.abcd/work/issues/open/iss-2609100519128005-a-refused-capture-writes-its-error-as-json-to-standard-error.md new file mode 100644 index 00000000..5f7dbc22 --- /dev/null +++ b/.abcd/work/issues/open/iss-2609100519128005-a-refused-capture-writes-its-error-as-json-to-standard-error.md @@ -0,0 +1,14 @@ +--- +schema_version: 1 +id: "iss-2609100519128005" +slug: "a-refused-capture-writes-its-error-as-json-to-standard-error" +severity: "major" +category: "ux" +source: "agent-finding" +found_during: "autonomous-run field experiment in a managed repository, 2026-09-10" +origin: researcher-authored +production_mode: hand-written +found_at: "internal/surface/cli" +--- + +A refused capture writes its error as JSON to standard error and leaves standard output empty, and an operator concluded from that shape that two captures had been silently lost.

The fields exist to attest which rubric and which prompt produced a verdict, and `ingest` writes them into the shipped intent's Audit Notes, which is a permanent record. As it stands the verb cannot be completed without fabricating that attestation, so the record gains a provenance claim that looks verified and is not. A reader cannot tell a host-computed hash from an invented one, and the disagreement between auditors means the same field means a different thing on different intents.

The defect is not fabrication by the auditor.

Failing that, `ingest` should either accept empty hashes and record them as absent, or refuse with a message naming what the host expects to be hashed. Any of the three is better than a required field with no supported way to fill it. Workaround: none that preserves the record's integrity. The verdicts were left uningested pending a decision, because ingesting them would write 13 fabricated attestations into the durable record.

They are committed together rather than split four ways because the generated surface files carry additions from several of them at once and cannot be separated; the records say which change answers which. Redaction no longer corrupts a reverse-DNS identifier whose first component is the account name. The detector suppresses a bare-username match only where it is an entire component of a dotted run of three or more, so a bundle identifier and a module path survive while a bare mention, a two-part filename and an email local part still fire. Before the fix the identifier was masked in the record's body and in its filename; the residue, that masking still rewrites by whole string rather than by byte span, is recorded separately because reversing that is a design decision in the one sanitiser every write path shares. The refusal that protects a write from a degraded scanner is now asserted, on seven paths rather than the three named: the sweep listed every unavailability site, and the decision record, the intent redactor and the lifeboat pack were unarmed beyond the finding's scope and are armed too. An unasserted guard on a fail-closed path is indistinguishable from an absent one. Ingest now verifies that its destination's repository root and its store key name the same repository, and fails closed when the root's own root commit will not resolve. The seam exists so that a transcript is never redacted under another repository's configuration, and it was trusting its caller to supply a pair it never checked. A session's sub-agents are reachable from the session identifier: `history list --session` is the set verb's front door, the human render carries the agent and its type, and `show` points at the set. The plugin page documents the flag and the lineage fields, which is what the JSON-only route lacked. A machine-readable refusal is now on standard output and says what it is, because a consumer that merges the streams could not tell a refusal from a success without the exit status the merge discarded. All three closed enumerations now name their accepted set when they refuse a value, rather than naming only the value. The findings gate can no longer be cleared by deleting the record it exists to protect. A deletion is a distinct refusal from an unfixed finding, because the remedy differs: the record must come back before it can be resolved, and a waiver is deliberately not consulted, since a deleted record carries no promise to re-ask. A record id sitting in two status folders now refuses every read of the ledger. Folder membership IS the status, so an id in two of them has no status at all. AGENTS.md no longer tells an author to coordinate an ADR mint that needs no coordination, and the correction is pinned by a test that mints an id and then refuses a router contradicting it, so the prose is held to behaviour rather than to another page of prose.

Measured across all four record families, the filename-derived and frontmatter-derived id sets are identical, 1725 against 1725, with no id that only one side can resolve, and the record-schema gate's filename-to-id leg is what keeps it so.

Measured: 223 mentions, 35 distinct ids, 67 record files. Illustrative ids that exist to describe gate behaviour. Pruned or never-migrated ids narrated historically. Forward references to records not yet minted, one of them a frontmatter field. And a residue of genuine suspects, including one truncated id sitting in a record's own slug.

Masking for identity kinds replaces every occurrence of the matched string rather than the span the detector found, which is recorded as deliberate because an identity placeholder changes length. So where one line contains a genuine bare mention of the account name and also an identifier that merely begins with it, the first is masked correctly and the second is mangled anyway: a line reading that the crash is in a particular reverse-DNS bundle comes out with the bundle's first component replaced, even though detection refused it. The same mechanism turns an ordinary word containing the account name into a masked fragment mid-word when a real mention appears on the same line, though detection alone leaves that word intact. A whole-string replace cannot express one occurrence masked and another left, so the fix is span-based replacement for identity kinds. That is safe on offsets, because the sealing pass is length-preserving, but it reverses a recorded design choice in the single shared write-time sanitiser that history, memory, capture, ideate, intent, decide and launch all write through, and it reverses it in the fail-open direction.

The issue-resolution gate refuses exactly this shape already, RS001 holding that a bare delete of an open record satisfies no trailer, so the two gates disagree about what counts as an answer while sitting in the same release path. The fix is to ask the question the sibling gate asks: a record present at the anchor and absent at HEAD is a deletion rather than a disposition, and the gate should refuse it and name it, since a record that entered the ledger and left it without reaching a terminal folder is the one case nobody can audit afterwards. Detector: a cut whose only change to a blocking record is its deletion must refuse, naming the record and the deletion, while a resolution, a wontfix and a deferral each continue to clear it.

The fixes are in f8541182; these are the records catching up with them. One of the three is stamped breaking rather than fix. Making a machine-readable refusal self-describing on standard output also means two verbs that render and then fail now put two documents there where they put one on each stream before.

It is meant to be a judgement, so each of these carries its own reason rather than a shared formula, and each names why it wants a decision rather than a patch. They divide into four kinds. Some are capabilities wearing a defect's clothes: the release flow for a managed artefact that is not a plugin, an errata mechanism for a durable record, a surface that counts owed reviews, a substrate that records which session holds what. Some are choices between defensible bargains that the evidence does not settle: the lock's backoff ceiling, the typed relations the decomposition discipline names but the format cannot carry, what a hazard guard should cover beyond shell calls. Some would reverse a recorded decision: making identity masking span-based rather than whole-string reverses a contract every write path in abcd shares, in the fail-open direction, and the public banned-names list cannot be created on a fresh public repository because the visibility fence is a documented contract with three candidate reconciliations already recorded for a maintainer to pick between. And one is not a defect at all: the synthesis that the record verbs are sound and the failures are at the edges, where the tool knows something and does not say it, which is a lens over the others rather than a thing to fix. Two deferrals carry news. The session-URL finding is half closed in this cut, its CI half gated and its local half blocked on three product decisions about how a git hook resolves a binary it has no plugin root to find. The unredactable staged text from a deleted repository no longer sits in the store at all: the owner moved it out, with a note recording why nothing could ever process it, so what is deferred is the mechanism and not an exposure.

A link at the PATH target that resolves to nothing made install refuse forever. The repair existed and was unreachable, because the detector classified every non-owned link as a foreign occupant to be hand-resolved. The discriminator is now danglingness rather than provenance: a link resolving to a file is somebody's install and is still refused untouched, while a link resolving to nothing runs nothing and is cleared. abcd does not attempt to prove it wrote the link, because it cannot, and the write-through hazard is closed by removing the link rather than writing through it. An unconditional plugin-manifest read refused on any repository that declares no plugin. The record named one site; the refusal a user actually sees came from a second, so both are fixed, because fixing the named one alone would have left the changelog verb dying exactly as before. Absence now comes from the payload tree's own answer rather than from classifying a read error, so a present-but-unreadable or malformed manifest still refuses, and a manifest that was declared at the last release and has gone is still caught as a removal against the baseline rather than vanishing into an error that yields no verdict.

The previous commit swept two files of this work into a commit about dangling install links without the primitive they call, leaving the branch tip unable to build. That primitive is here, so the tip builds again; the broken commit stays in history rather than being rewritten, because it is local and the honest record of what happened. The record naming which binary the hooks may execute was honoured without anyone checking who could write it. Four read sites accepted a group-writable or foreign-owned record, the presence test followed a symlink, and in the proving test all five hooks executed an attacker-named binary. One primitive beside the existing guarded read now checks link, regular file, mode and owner before reading, and the two existing copies were migrated onto it rather than a third being written. The shims ask the same question with a single file test instead of parsing a listing, which avoids field-position, locale and access-control-suffix assumptions, catches the symlink shape, and fails closed when its tools are absent. This was NOT fixed by the previous release; it was believed to be. The fidelity-review request now carries provenance the host computed, and the ingest verifies it rather than checking its shape. The rubric hash covers the contract this binary enforces, written verbatim into the request so the auditor echoes the bytes that were hashed; the prompt hash covers the request minus its own provenance block, which the ingest recomputes. The measured scale was much worse than the record claimed: thirty-six ingested verdicts, thirteen distinct rubric values, and two digests appearing under both field names, so the field name carried no meaning across the corpus. Those thirty-six are deliberately left as they are, because editing committed audit notes would lay a second fabricated provenance over the first. Privacy hygiene no longer fires on the two shapes the conventions mandate, which is what made it unreadable at a hundred and fifty findings. One half of that removes a detection and says so in its record rather than hiding in a diff: the shared-root exemption now covers the subtree, so a third party's name directly beneath one yields nothing, where the committing user's own name there still hard-fails.

The cause is this cycle's own work: roughly fifty new records from a three-session field experiment on abcd's gaps, plus the intents, specs and decision record that carried the sub-agent capture work, all of which the widening, entailment and detection positions read over. Each is re-measured at this commit and moved to the smallest ten-thousand boundary leaving at least one per cent headroom, which is the rule the entries already state. Nothing about what a position reads has changed, so the kinds are untouched and only the declarations move. This is the honest half of a gate that could have been silenced instead. The alternative the failure offers is to narrow an entry's kinds, which would have made the number fit by reading less, and none of these entries is reading anything it should not.

The product thinker confirmed all four as intents. Each is promoted from its issue so the back-edges are stamped, and the brief's later-phase index carries the four. The routing is graded into the calibration note.

A line carrying one genuine mention and one lookalike had the lookalike corrupted too, so the record no longer held the technical content it existed to hold. The rewrite now masks exactly the byte spans the detector recorded. Spans are validated against the line before the secret seal and applied after it, which the seal's byte-length preservation makes safe; overlapping spans merge into one cluster masked with the widest member's placeholder; and the line is rebuilt from original bytes, so a placeholder of any length never shifts a later span. The cost is accepted with the decision and named in the code: an occurrence the detector clears on purpose — a login inside a URL, including a credentials URL's userinfo — is no longer masked by accident, and the second-stage re-scan does not flag it either, because it is the same detector. The caller's own home path is outside that residue, because the detector flags every occurrence by the anchor the literal sweep uses; history, memory and ideate additionally run that sweep after redaction. Each proof was watched failing first: the record's own measured case, the mid-word case, two genuine mentions on one line, offsets across several length-changing placeholders, the same behaviour for a forge login and a real name, the seal's length preservation, byte-offset columns under multi-byte runes, and the fail-open residue pinned so it is known rather than discovered. A review found the one path that could still reach the whole-string fallback from a real scan — an identity span overlapping a sealed secret — and it is closed by validating against the pre-seal bytes, with its own test.

The reviews found the expensive parts unsound as drafted: a `claimed_by` stamp on an issue record is invisible to any peer on an older binary, because `issueschema.Known` is a closed allow-list whose reader refuses and skips a record carrying an unknown key and `record_schema` mirrors the refusal into the gate, and version skew is the steady state here (five plugin-cache vintages beside a `go run` checkout); the write-verb refusals fire after the fix is written, because `AGENTS.md` puts `capture resolve` in the same change as the fix; no staleness threshold is safe in both directions for two sessions in one worktree, since the worktree-exists and branch-merged tests are identical for both and a host may fire session-end on a context clear with the human still present; and the pushed half costs a merge-queue pass per claim, measured at fifteen to sixteen minutes on this repository's merge-group `ci` leg. Every collision on record is one of two claim-free shapes. The ruling: itd-2609091416295622 carries the read-only sibling-worktree ledger diff over `git worktree list --porcelain` (no claim, no lease, no hook, no threshold; the piece that ships soonest); itd-2609091416304128 carries `capture resolve` and `capture wontfix` refusing a record terminal at the local `origin/main` ref as last fetched, stating the ref's age and fetching nothing, with the same judgement rendered read-only on `abcd <record-id>`; itd-2609091034175565 keeps the claim, the lease and the refusals as a draft marked not ready, carrying the refusal-surface, liveness and pushed-price questions as open questions and the two-release stamp migration as a hard constraint. The existing record stays the claim so the `promoted_from` trail from iss-2609020716570699 — whose remedy is the claim and the pushed half — stays true rather than being retitled onto a listing the issue never proposed; the two new records reach the issue through `related_intents` on the issue and on themselves, and every relation the schema cannot type is stated in prose as a prose cross-reference (iss-2609091256264547).

The detector was taught to leave a dotted namespace component alone, which fixed the corruption of reverse-DNS identifiers. The rewrite did not learn it. Masking for identity kinds replaces every occurrence of the matched string rather than the span the detector found, which is recorded as deliberate because an identity placeholder changes length. So where one line contains a genuine bare mention of the account name and also an identifier that merely begins with it, the first is masked correctly and the second is mangled anyway: a line reading that the crash is in a particular reverse-DNS bundle comes out with the bundle's first component replaced, even though detection refused it. The same mechanism turns an ordinary word containing the account name into a masked fragment mid-word when a real mention appears on the same line, though detection alone leaves that word intact. A whole-string replace cannot express one occurrence masked and another left, so the fix is span-based replacement for identity kinds. That is safe on offsets, because the sealing pass is length-preserving, but it reverses a recorded design choice in the single shared write-time sanitiser that history, memory, capture, ideate, intent, decide and launch all write through, and it reverses it in the fail-open direction.

The decisions log becomes a folder of individually minted records with a derived index, and the log's path a symlink to that index for now. The question first asked was how adoption should propagate the merge-attribute workaround into a managed repository; the answer came from the same run's positive finding, that the five one-file-per-record families never conflicted across twenty-seven merges while the two single appended files conflicted on nearly every one. The rule is an accepted decision record; the capability is an intent draft carrying the migration, the index, the adoption path and the retirement of the decisions-append gate as its acceptance criteria. An intent owns one or more specs and ships when its last spec closes. A spec that delivers part of a thought-through intent is closed on its own terms and a new spec is minted for the remainder; the intent moves only when no open spec names it. The rule is a decision record and invariant 17 of the brief; its build is owed, and the issue that asked for it stays open until it lands. Banned names get both halves: a committed declaration lifts the public visibility fence so a fresh public repository can create its committed list on its first commit, and a machine-global private list in the user-level home bans a name in every repository on the machine, never read by CI. Filed as an intent draft promoted from its issue.

The instrument's own output is never its input, with one positional exception adr-2609021016272867 states: at the comparative position, two body fields of one derived widening run's items are admitted as that reading's candidate set, and everything else in the readings store stays excluded — and the reading runs context-isolated — the assembled input is its entire working set, and no repository or home path enters its context. The scribe context is the inverse: ledger content only, never the shipped repository as an object of judgement, and not a transcript consumer. No session holds both a reading and the ledger: every reading bundle and every scribe context carries a per-run context stamp, and the session store's separation check reports a retained transcript carrying both stamps of one run, reports what it saw when none does, and reports the property as unobserved rather than clean when no transcript carries any stamp (per [adr-2609021016275803](../../decisions/adrs/2609021016275803-no-session-holds-both-a-reading-and-the-ledger-and-a-per-run.md)).

Every other surface is denied: the cold readings structurally (store outside the repo tree by default and, when pulled in, under the `.abcd/.work.local` tier the assembler denies by segment, drops by the tracked-set intersection and refuses by asserted exclusion; positive inclusion, isolation, transcript-class sentinels in the read-block eval), everything else by this enumeration. A new consumer is a change to this invariant, never merely a code path; mechanically, only the history core package touches the store's path, held by `TestOnlyTheHistoryPackageNamesTheStorePath` (`internal/core/history/store_boundary_test.go`): it parses every non-test Go file under `internal/` and `cmd/` and refuses a string literal spelling the store — the user-level default, the opt-in per-repo pull-in, the declaration that enables it, or the legacy location the corpus was moved out of — anywhere but that package, with each exception declared by file and by literal so a second spelling is a new decision. The cold-reading assembler's exclusion row is the one declared exception, because it names the path in order to deny it and never resolves, reads or writes it. 16. **An exclusion control asserts only what it can prove** — a control that cannot examine an input refuses it, naming it, rather than admitting it silently; an attestation (a manifest, receipt or verdict) never states more than the examination behind it establishes, so a scan that ran and found nothing and a scan that never ran do not produce the same artefact; and where a system admits inputs through one surface and examines them through another, the two surfaces describe one set, whichever of them has to move, or the attestation marks per item what the examination did not reach (an opted-in source or test item a reading is handed travels whole and marked unscanned, per the 2026-09-02 ruling that refines adr-56). Per [adr-56](../../decisions/adrs/0056-an-exclusion-control-asserts-only-what-it-can-prove.md); the `loud-staging` principle applied to a control rather than to a stage; implemented first by itd-194 over the cold-reading assembler, whose floor declined to scan what it could not parse while the manifest asserted the exclusion anyway, and inherited by every later verb whose output is an attestation a third party relies on. + +17. **An intent owns one or more specs, and it ships when its last spec closes** — the intent↔spec relation is 1:n: an intent that has been thought through stands as written, so a spec that delivers only part of it is closed on its own terms and a new spec is minted for the remainder and attached to the same intent (spec closed X, spec open Y, intent still `planned/`); closing a spec never ships an intent that still has an open spec, the intent moves `planned/` → `shipped/` on the close after which no open spec names it, that move stays automatic and never hand-asserted, and the `--impact` judgement `shipped/` requires is demanded at that transition and at no earlier close. More than one spec naming one intent is the normal state and not an ambiguity; a bundle ([`04-surfaces/05-intent.md`](../04-surfaces/05-intent.md)) is the opposite relation (N:1, several intents sharing one spec) and is untouched.

Two storage shapes, one day, one set +of branches: the one-file-per-entry families produced zero conflicts and the +single-file logs produced conflicts on nearly every merge. Nothing about the +content differs — a decision line and an issue record are both short, dated and +independent. What differs is whether two concurrent writers touch the same +region of the same file. + +The log itself anticipated this. `.abcd/work/DECISIONS.md`'s header has carried +the instruction since it was written: "Graduate this file to per-file +`decisions/<date>--<slug>.md` if size or parallel-agent merge contention bites." +It has now bitten, measured, at 330 entries and 2,489 lines. + +Three constraints were already locked before this decision. Record ids are +minted through one timestamp-numeric allocator that reads no maximum +([adr-45](0045-record-ids-are-timestamp-numeric-and-capture-stable.md)), which +is what lets two checkouts mint in the same window without coordinating — and +since the ruling of 2026-09-01 that allocator serves ADRs too, so a sixth family +is a caller of an existing seam and not a new mechanism. The record +information architecture already treats folder membership as the status signal +for a family stored one file per record +([adr-30](0030-record-information-architecture.md)). And the decisions-append +gate `scripts/check-decisions-append.sh` (DA001–DA004) exists precisely because +a single appended file has a position to police: an entry inserted mid-file, a +historical entry reworded, a merge that authors a line no parent had. + +What forces the decision now is that the workaround does not travel and does not +scale as a stance. The union attribute is a per-repository `.gitattributes` +entry that abcd would have to write into a repository it adopts, on a path that +repository's user owns; it makes the interleaving of two concurrent appends +non-deterministic; and it is correct only while every entry is independent and +dated, a property nothing checks and nothing enforces. Scaffolding it into +somebody's repository unasked is the act this project's own rule about +user-owned space +([adr-2609091248200336](2609091248200336-a-tool-never-creates-directories-in-user-owned-project-space.md)) +tells it to think twice about. The shape needs no attribute anywhere. + +## Decision + +**A decision is a record, minted like every other record, stored one per file.** +The decisions log is a folder. Each entry is a file carrying an id allocated +through the adr-45 seam — the same allocator captures, intents, specs and ADRs +already mint through — with its date and its text. Recording a decision creates +a file and appends to nothing. + +**An index is assembled from the folder, and it is derived, never appended to.** +The index lists every entry in dated order with its id, so the reading experience +the single file gave is recovered. It is produced from the folder's contents; the +minting verb does not write to it. A committed index that every mint also +appends to would move the conflict rather than remove it, and that is the one +construction this decision forbids by name. + +**`.abcd/work/DECISIONS.md` becomes a symlink to that index for now.** Every +existing reader, link, citation and convention that names the path keeps +resolving, and nothing has to be rewritten in one sweep to make the shape land. +A later intent may assemble a single file automatically if that reads better; the +symlink is the compatibility form, not the end state, and the decision does not +pre-empt that choice. + +**This applies to abcd itself and to every repository abcd manages.** A managed +repository does not get the single file plus a merge attribute scaffolded into +its `.gitattributes`. It gets the shape, at adoption, the same shape abcd +carries. + +**The decisions-append gate is retired by the shape, not disabled.** DA001–DA004 +check position, preservation, merge authorship and byte-cleanliness inside one +appended file. A folder of individually minted files has no mid-file position to +insert into: an entry is added by creating a file, a historical entry is +protected by the same durability rule every other record family lives under, and +a merge that authors a line no parent had is not a shape git can produce from two +disjoint file additions. The gate goes when the shape lands, in the same change, +and nothing is left invoking it. + +The delivery is +[itd-2609151138388536](../../intents/drafts/itd-2609151138388536-append-only-logs-conflict-on-every-merge-in-a-managed-repo.md). +This record is the rule; that intent is the capability, with the migration, the +index assembly, the adoption path and the gate retirement as its acceptance +criteria. + +## Alternatives Considered + +1. **Keep the single file and propagate the union merge attribute to every + managed repository.** The cheapest option, and the one the field session + actually performed: a one-line write into a file adoption already touches, and + it demonstrably stopped the conflict for the remaining 25 merges. Rejected on + three grounds. It writes into a file the user owns, on a repository abcd + adopts rather than creates, which is the act adr-2609091248200336 is about. It + is correct only under an unchecked precondition — that entries are independent + and order-insensitive — so the day somebody writes an entry that amends + another, union merges both silently and nothing notices. And it buys nothing + for the changelog, the other half of the same finding, where union is actively + wrong because it duplicates headings: a remedy that closes one of two + identical-looking classes and leaves the other is worse than one that names the + difference. + +2. **The folder for abcd only, while managed repositories keep the file and the + attribute.** Attractive because abcd controls its own history and can migrate + in one change, while a managed repository's log is somebody else's file. + Rejected: it makes the tool's own conventions and the conventions it ships two + different things, which is the failure mode this project keeps catching in + other forms — abcd had already answered both halves of this finding for itself + and neither answer travelled, and that non-travelling is exactly what + iss-2609100507439414 is a report of. A rule that holds only where the author + works is not a rule. + +3. **Keep the single file and accept the conflicts.** Defensible at one branch at + a time, where the file never conflicts and the folder buys only consistency. + Rejected: the measurement is from parallel work, and parallel work is the + direction of travel, not an edge case. The cost is not the conflict itself but + what a conflicted append-only ledger invites a session to do at two in the + morning — resolve it by hand, drop a side, or reorder history — against a gate + whose whole purpose is to refuse exactly that. + +4. **Chosen: a folder of individually minted decision records, with a derived + index and `DECISIONS.md` as a symlink to it, in abcd and in every repository + it manages.** It removes the conflict class rather than patching it, needs no + `.gitattributes` entry anywhere, puts decisions on the same footing as the five + families that were measured not to conflict, and retires a gate instead of + adding one. + +## Consequences + +- **Two branches recording a decision stop conflicting, with no configuration.** + Git sees two file additions and reconciles them without help. Nothing has to be + written into `.gitattributes`, in abcd or in any repository it adopts, and the + interleaving question disappears rather than being answered + non-deterministically. +- **Decisions join the record families and inherit their tooling.** An id, a + file, a folder — the same shape the citation resolver, the `abcd <record-id>` + dispatch, the lifeboat packer and the record gates already read. A sixth family + costs the adr-45 seam nothing, which is what a seam is for. +- **Reading the whole history gets harder before the index makes it easier + again.** A single file is grep-able, scroll-able and diff-able in one pass; 330 + files are not. The assembled index is what recovers that, and it is now + load-bearing rather than a convenience — if the index is absent, stale or + unassembled, the decision history is materially less readable than it was + before this change. That is the real cost of the decision, and it is paid in + a piece of machinery that has to work. +- **Every existing reference to `.abcd/work/DECISIONS.md` keeps resolving — + through a symlink, which is a new dependency.** `AGENTS.md`, the brief, the ADR + README and many records name that path. The symlink means none of them changes + on the day the shape lands. It also means a platform or a tool that does not + follow symlinks now sees something different from what it saw before, and that + the interim form is one more thing to remove when the end state is chosen. +- **The decisions-append gate goes, and with it a body of careful work.** + `scripts/check-decisions-append.sh` and its case suite encode four rules and a + long argument about why position alone is not append-only. Retiring them is a + net simplification, and it is also the deliberate loss of a check nothing + replaces: after this change, a decision record's immutability rests on the same + convention every other record family rests on — a durable record is superseded, + not edited — with no gate behind it. If that convention needs mechanical + enforcement, it needs it for all six families, not for one file. +- **The existing log's 330 entries have to be migrated, and the migration is the + risky part.** Each entry becomes a file with an id, its date and its text + preserved verbatim, in its original order. A migration that drops, reorders or + reflows history is worse than the conflict it fixes, which is why the intent + makes verbatim preservation and a matching count an acceptance criterion rather + than an implementation note. +- **A managed repository's existing log is somebody else's file.** abcd rewrites + its own in a change it controls. What adoption does to a repository that + already has a `DECISIONS.md` — migrate it, offer to, or apply the shape only to + new decisions — is left open in the intent, because the answer is a question + about how opinionated adoption is allowed to be and not about file shape. +- **The changelog half stays open, and is not closed by this record.** + `CHANGELOG.md`'s `[Unreleased]` section is the other single append-to-the-bottom + file, and union is the wrong remedy for it. abcd solved it for itself by + deriving the changelog from records at the cut and refusing a non-empty + `## [Unreleased]`; what a managed repository lacks is the ability to use that + flow, which is + [itd-2609150819432059](../../intents/drafts/itd-2609150819432059-abcd-launch-cannot-set-up-the-release-flow-for-a-managed-rep.md). + Neither record refines the other; both conflict classes close only when both + land. +- **The union attribute for `CHANGELOG.md` stays where it is.** This record + retires the attribute for the decisions path, once that path is a symlink to a + derived index.

Whatever the +session did next would have been a false record: ship an intent whose criteria +are half unmet, or leave finished work uncommitted to the ledger. + +A shipped intent with unmet criteria is the false-green shape at the level of +the record, and it is expensive in three places at once.

Both records +are about a close that does more than close, silently.

The native spec store +is the scheduling home for a committed capability +([adr-26](0026-native-spec-layer-ccpm-backend.md)). Terminal folder membership +is what the release reads, so nothing user-facing is announced until a record +reaches one ([adr-31](0031-derived-versioning-from-intents.md)). `shipped/` is +the one bucket the record gate requires an `impact` judgement in, and +`resolveShipImpact` runs ahead of every write for the reason +[iss-126](../../../work/issues/resolved/iss-126-intent-reconcile-cannot-stamp-impact.md) +gives — abcd must not produce, out of its own verbs alone, a record its own +record-lint refuses. And an intent's acceptance criteria are the verifiable bar +for "shipped", per the [itd-1](../../intents/disciplines/itd-1-acceptance-gates.md) +discipline. + +What the tree cannot currently represent is the shape the field case needs. The +link is 1:1 on both sides: an intent carries a scalar `spec_id`, a spec carries a +scalar `intent`, and `Reconcile` refuses outright when more than one spec claims +one intent — "link ambiguous — N specs realise itd-X". So a second spec for the +remainder is not merely unsupported today; minting one makes the close of the +first refuse. + +## Decision + +**An intent owns one or more specs.** The relation between an intent and the +specs that realise it is 1:n. One spec remains the ordinary case and needs no +ceremony; a second exists whenever delivery did not fit in one piece of +scheduled work. + +**An intent is a thought-through statement of a capability, and delivery never +rewrites it.** Where a spec delivers part of an intent, the intent stands as +written. Narrowing its acceptance criteria to match what was built is not +available: it would make the record agree with the delivery by falsifying the +thing the product thinker decided. + +**A spec that delivers part of an intent is closed on its own terms, and a new +spec is minted for the remainder and attached to the same intent.** The visible +state after that operation is exactly what happened: spec closed X, spec open Y, +intent still `planned/`. + +**Closing a spec never ships an intent that still has an open spec.** The close +of a spec is a statement about that spec's work and about nothing else. + +**The intent ships when its last spec closes.** That transition — the close +after which the intent has no open spec left — is the one that moves it +`planned/` → `shipped/`, and it stays automatic. Nothing is shipped by hand. + +**`--impact` is still required at the ship transition, and only there.** The +judgement is what `shipped/` requires and what the derived version reads, so the +close that ships the intent demands it exactly as today; an earlier close, which +ships nothing, must not ask for it. + +**More than one spec naming one intent is the normal state, not an ambiguity.** +The guard that refuses it is refusing the shape this record establishes, and it +is replaced by the question that actually matters: does this intent have an open +spec left? + +## Alternatives Considered + +1. **Close still means ship, and the intent is narrowed to what was + delivered.** The cheapest reconciliation, and the one that needs no code: edit + the acceptance criteria down so the shipped record is true of what was built, + and file the rest as a new intent later. Rejected, and this is the one the + product thinker ruled out by name. An intent that has been thought through is + the statement of the capability; rewriting it at delivery time makes the + record agree with whatever happened, which is the opposite of a bar. It also + destroys the evidence: after the narrowing, nothing in the tree says the + intent was ever wider, so the missing half is not deferred work but a thing + nobody can find. + +2. **A spec may close without shipping, and the intent is shipped by hand.** A + `--no-ship` flag on the close, or a separate ship verb the operator runs when + the intent is genuinely done. Rejected: it is the shape this project has + repeatedly found to fail, because the step that happens after the merge is the + step that gets forgotten. It also moves the shipped claim out of the record + and into somebody's memory of what they meant to do, and an intent left in + `planned/` with all its specs closed is invisible to the release cut, which + then under-bumps and announces nothing. + +3. **Split the intent at close: mint a successor intent for the unmet criteria + and ship the delivered half.** The source record's own second suggestion, and + attractive because it needs no new cardinality — every intent keeps one spec. + Rejected on the same ground as option 1, one level up. The press release is + one user moment; cutting it at the boundary where delivery happened to stop + produces two records, each describing half a moment, and the split is made by + the accident of what fitted in a cycle rather than by a decision about the + product. A thought-through intent should not have to be re-thought because a + cycle ran out. + +4. **Keep the 1:1 coupling, but refuse the close when the intent's criteria are + visibly unmet.** The source record's fallback: at minimum, do not move it + silently. Rejected as a remedy on its own, because nothing in the system can + read acceptance criteria and decide they are met — that judgement is the + fidelity audit's, and it runs after the ship. A refusal that cannot evaluate + its own condition degrades to a prompt on every close, which is a step people + learn to clear rather than read. The honesty it asks for is real; it is + delivered here by making the true state representable instead. + +5. **Chosen: an intent owns one or more specs; a partial delivery closes its + spec and mints another for the remainder; the intent ships when its last spec + closes.** It leaves the intent intact, keeps the ship transition automatic and + derived rather than hand-asserted, and makes the state the field case was in — + work finished, capability not yet whole — a state the record can hold instead + of a dilemma the session has to resolve by lying in one direction or the + other. + +## Consequences + +- **`spec close` gains one question and loses one refusal.** After closing the + spec, it asks whether any other spec naming that intent is still open. If one + is, the intent stays in `planned/`, the verb says so and names the open spec; + if none is, the intent ships exactly as today, with `--impact` resolved ahead + of the move. The ambiguity guard in `intent.Reconcile` — which today refuses + when more than one spec claims an intent — inverts: the set of claiming specs + stops being an error and becomes the input to the question. +- **The record schema has no field for this today, and something has to carry + it.** An intent carries a scalar `spec_id` and a spec carries a scalar + `intent`; nothing anywhere carries a list. The two shapes available are to make + the spec's back-link the single source of truth and derive an intent's spec set + from the store, or to let the intent carry the set explicitly. This record does + not pick between them, and it does bind the requirement either must meet: the + question "does this intent have an open spec" is answerable from committed + records alone, and the link stays checkable in both directions rather than + becoming one-sided. Whichever shape is chosen, the bidirectional-agreement + check that `Reconcile` performs today has to keep meaning something. +- **Three readers assume one spec per intent and each has to learn otherwise.** + `lint.SpecLinkIndex` (`internal/core/lint/speclinks.go`) maps each intent to one + raw `spec_id` and resolves one id to one bucket; the `spec_lifecycle` rule + reads that index; and the release cut's `staleIntents` + (`internal/core/release/emit.go`) refuses a cut for any intent in `planned/` + whose linked spec has closed. That last one is the sharpest: under this rule a + planned intent with one closed spec and one open spec is the correct steady + state, so the check as written would refuse every release taken during a + partial delivery. It must ask whether the intent has any open spec, not whether + its spec has closed. Left unchanged, this decision turns a lifecycle rule into + a release wall. +- **A half-delivered capability is not announced, and the release notes lag the + merge.** The changelog is composed from terminal folders, so an intent that + stays planned while its second spec runs contributes no line, even though its + first spec's code is on the default branch. That is the intended behaviour — + the announcement should describe a capability, not a fraction of one — and it + is a real cost: for one or more cycles, shipped code is live and unannounced. + The honest record of it is the open spec, which is visible in the ledger the + whole time. +- **The fidelity audit runs once, over more than one spec's delivery.** The + intent-auditor compares a shipping intent's acceptance criteria against the + delivered diff and runs at the ship transition. Under this rule that transition + arrives later and the delivery it has to read spans every spec the intent + owned. The audit's scope widens accordingly; what it is asked — did the + delivery honour the criteria — does not change, and asking it once about the + whole intent is closer to its purpose than asking it about a fraction would + have been. +- **A bundle is the opposite cardinality and is untouched.** `kind: + bundle-member` with a `bundle:` link is N:1 — several intents sharing one spec, + moving together when that spec closes, governed by the invariant that every + member belongs to one phase + ([`04-surfaces/05-intent.md`](../../brief/04-surfaces/05-intent.md)). This + record is 1:n — one intent, several specs. They are different relations, not + two names for one thing, and nothing here changes the bundle rule or its + invariant. Composing the two would be N:M; no case requires it, and this record + does not authorise it. +- **An intent's specs may be scheduled in different phases.** The reason a second + spec exists is that the work did not fit the cycle that carried the first, so + requiring both in one phase would forbid the case the rule is for. That is a + deliberate asymmetry with the bundle invariant above, and it follows from the + cardinality rather than contradicting it: a bundle's members share one spec, and + one spec has one phase. +- **The rule makes the honest path available; it does not make the dishonest path + impossible.** Nothing forces the remainder spec to be minted. A session that + closes the last open spec while criteria remain unmet still ships an intent that + is not delivered, exactly as today.

In the same +27 merges — 33 issue resolutions, 5 intents shipped, 3 ADRs superseded, 1 ideate +verdict — the record store did not conflict once. Every one of those five +families is one file per entry. The two files that conflicted are the two that +are single, append-to-the-bottom files. The conflict is a property of the file +shape, not of the content or of the branching. + +The log itself has said so since it was written. `.abcd/work/DECISIONS.md`'s own +header carries the instruction: "Graduate this file to per-file +`decisions/<date>--<slug>.md` if size or parallel-agent merge contention bites." +It has now bitten, in a measured run, at 330 entries and 2,489 lines. + +The remedy applied in the field — the union merge attribute — works, and it is +the reason the log stopped conflicting for the rest of that run. It is still a +patch on the shape rather than a fix of it: it needs a `.gitattributes` entry +written into a repository abcd adopts, it makes the ordering of two concurrent +appends non-deterministic, and it is safe only for entries that are independent +and dated, which is a property nothing checks. A folder needs none of that. + +This intent closes one of the run's two conflict classes. The other is the +changelog, whose `[Unreleased]` section has the same shape and where union is +**not** safe — it duplicates the `###` headings. abcd answered that half for +itself by deriving the changelog from records at the cut and refusing a non-empty +`## [Unreleased]`; what a managed repository lacks is the ability to use that +flow, which is +[itd-2609150819432059](itd-2609150819432059-abcd-launch-cannot-set-up-the-release-flow-for-a-managed-rep.md). +This intent `refines` nothing of itd-2609150819432059's, and itd-2609150819432059 +`refines` nothing of this one's: they are disjoint. Together they close both +conflict classes, and neither closes both alone. The typed link is a companion +link, recorded so that a reader who finds one half does not conclude the other +half was overlooked. + +The shape rule this delivers is +[adr-2609151138420062](../../decisions/adrs/2609151138420062-the-decisions-log-is-a-folder-of-minted-records-not-one-appe.md). +The id seam it mints through is +[adr-45](../../decisions/adrs/0045-record-ids-are-timestamp-numeric-and-capture-stable.md), +which is already the allocator for captures, intents, specs and — since the +ruling of 2026-09-01 — ADRs; a sixth family costs the seam nothing, which is the +point of having a seam. + +## Mechanism + +We expect this to remove the conflict class rather than reduce it **because a +merge conflict requires two sides to have edited overlapping regions of the same +file, and a folder of one-file-per-decision gives two concurrent decisions no +shared region at all.** The prediction is falsifiable in the shape of the +artefact, not in a statistic: if the assembled index is a committed file that +every decision also writes to, the conflict simply moves from `DECISIONS.md` to +the index, and the class is not closed — it is renamed. The index must therefore +be derived at read time or regenerated from the folder, never appended to by the +minting verb, and an acceptance criterion below is written to catch exactly that +failure. + +The secondary claim is that the readability cost is recoverable. A folder is +harder to read end to end than a file, and **we expect the assembled index plus +the `DECISIONS.md` symlink to recover that** — because the index is the file the +reader had before, and the symlink means no existing reader, link or citation +learns a new path. If a reader has to open 330 files to answer a question the +single file answered, the index has failed and the claim is wrong. + +## Scope Conditions + +- **Repositories using git.** The claim is about git's merge behaviour on file + boundaries; nothing here is asserted about another version-control system. +- **abcd itself and every repository abcd manages.** The shape is not optional + per repository: a managed repository that keeps the single file keeps the + conflict, and the decision that occasioned this record applies to both. +- **Parallel branch work.** The benefit is proportional to concurrency. At one + branch at a time the single file never conflicts and the folder buys nothing + but consistency with the other five families. +- **A filesystem with symlinks, for the interim `DECISIONS.md` form only.** The + folder and its index do not depend on symlink support; the compatibility + shim does, and a platform without it reads the index at its own path. +- **Decisions that are independent and dated.** This is the same condition the + union attribute silently assumed.

The +fence narrows to the local tier only once the namespace already holds tracked +files, because narrowing needs positive evidence — and a brand-new repository has +none. The guarantee is therefore unavailable in exactly the window that creates +the need for it: a rename or an extraction, which is precisely a new repository +with nothing tracked yet and a name it must never publish. + +The escape exists and is not discoverable: commit the record tiers first with +`git add -f`, against the tool's own fence, then re-run install so the fence +narrows, and only then write the store. Three steps, one of them forcing past a +gitignore the tool wrote a moment earlier, none of them named by the refusal. The +offered alternative — ban the name on the private layer instead — silently drops +CI enforcement, which is the entire point of the committed layer. + +That is a bootstrap paradox rather than a bug, and every route through it runs +into what public visibility is declared to mean. Three candidates were left for a +human to pick between in [iss-176](../../../work/issues/resolved/iss-176-public-banlist-family-unenforceable-under-public-visibility.md): +move the config outside the namespace, carve a single un-ignore into a table that +has no exceptions, or declare the committed layer private-visibility-only. +[iss-223](../../../work/issues/open/iss-223-public-visibility-fence-vs-committed-record-repos.md) +states a fourth shape from the other end — a committed-record declaration that +suppresses the fence — and its promotion [itd-159](itd-159-public-visibility-fence-vs-committed-record-repos.md) +is still an unfilled draft. **The product thinker's ruling on 2026-09-15 takes +that fourth shape, and takes a second capability with it.** + +**Half one: a committed declaration lifts the fence.** A repository says, in a +file the fence does not cover, that its record tier is meant to be committed. +That statement is evidence a repository can give on its first commit, which is +what detection of tracked files can never be. With it present, install narrows +the fence and the committed banned-names family is writable straight away. +Without it, nothing changes: the fence stands, the refusal stands, and the status +board still reads NOT ENFORCEABLE — this adds a door, it does not weaken a wall. + +**Half two: a machine-global private list.** A person's most sensitive banned +names are not a property of a repository at all. Hostnames, device names, network +prefixes, a private project's name: they are the same in every checkout on the +machine, and today they are declared once per repository in +`.abcd/.work.local/private-names.txt` — which means a new checkout starts +unguarded, and the warning that says so is easy to read past. abcd already has a +user-level home for machine-scoped state, keyed where a repository is involved on +the repository's root commit. Nothing in it holds a banlist, and nothing today +applies a banned name across every repository on a machine. The product thinker +put it as a question — the home exists, why is the list not there, or split into +a global section and a per-repo one — and the answer is that nobody has built it. + +**It was made explicit before the ruling that half two cannot rescue half one.** +A list in the user's home is invisible to CI by construction: a continuous +integration runner clones the repository and has neither the home nor any right +to it. So the machine-global layer cannot enforce anything for anyone but the +person whose machine it is, and it does nothing for the committed layer's reach. +The product thinker chose both halves with that limit stated: the declaration +makes the *committed* layer creatable when a repository most needs it, and the +machine-global list stops a person re-declaring their own names in every +repository they open. Neither substitutes for the other, and saying so is part of +what ships. + +The honesty rule this extends is [adr-56](../../decisions/adrs/0056-an-exclusion-control-asserts-only-what-it-can-prove.md): +a control asserts only what it can prove. Today the public layer's compliance with +it is total and unhelpful — it can prove nothing about a fenced config, so it +writes none and says so. The refinement is to give the control a fact it can +examine. What must not move is the claim itself: a machine-global list must never +be described, on any surface, as protecting anything a CI run sees. + +## Mechanism + +We expect a committed declaration to close the bootstrap paradox **because the +fence narrows on evidence, and a declaration is the one kind of evidence a +repository can produce before it has committed anything** — where detection of +tracked files is, by construction, the kind it cannot. The claim is falsifiable in +the artefact rather than in a statistic: if the declaration's own home sits inside +what the fence covers, it cannot be committed either and the paradox has been +relocated rather than closed. So the declaration lives outside the fenced +namespace, or the fence exempts exactly it and nothing else, and an acceptance +criterion below is written to catch a declaration that cannot be committed on a +fresh repository. + +We expect a machine-global private list to remove the per-repository cost of +declaring a name **because the names in question are properties of the person and +the machine rather than of any repository**, so one declaration covers every +checkout including the ones that do not exist yet. The falsifier is a boundary +crossing in either direction: if CI can read the home list, it is a published +pattern and the layer has become the committed layer with worse properties; if any +pattern from it reaches a committed file, the layer has leaked the exact class of +string it exists to contain.

Close the spec while leaving the intent planned, + with the reason recorded on the intent; or split the intent at close, minting a + successor intent for the unmet criteria and shipping the delivered half; or, + failing both, make the close refuse — or demand an explicit acknowledgement — + when the criteria are visibly unmet. The first two are the source record's own + "wanted" paragraph; the third is its fallback. +- **Confirmed routing:** the product thinker reframed the question before routing + it. Not "what should the verb do when an intent is half delivered" but "what is + the relationship between an intent and its specs" — and the answer is 1:n. An + intent that has been thought through stands as written, so a spec that delivers + part of it is closed on its own terms and a new spec is minted for the + remainder and attached to the same intent; the intent ships when its last spec + closes. That makes every one of the three initial options wrong in the same + way: each keeps the 1:1 link and buys honesty by narrowing something — the + intent, the shipped claim, or the operator's attention.

What + surfaced the better question was asking what the RECORD should be able to + represent rather than what the verb should do: the state the field session was + actually in — work finished, capability not yet whole — had no representation + at all, and once that is the question the cardinality is the answer and the + verb behaviour falls out of it.

The reviews found the expensive parts unsound as drafted: a `claimed_by` stamp on an issue record is invisible to any peer on an older binary, because `issueschema.Known` is a closed allow-list whose reader refuses and skips a record carrying an unknown key and `record_schema` mirrors the refusal into the gate, and version skew is the steady state here (five plugin-cache vintages beside a `go run` checkout); the write-verb refusals fire after the fix is written, because `AGENTS.md` puts `capture resolve` in the same change as the fix; no staleness threshold is safe in both directions for two sessions in one worktree, since the worktree-exists and branch-merged tests are identical for both and a host may fire session-end on a context clear with the human still present; and the pushed half costs a merge-queue pass per claim, measured at fifteen to sixteen minutes on this repository's merge-group `ci` leg.

Spans are validated against the line before the secret seal and applied after it (the seal preserves byte length), overlapping spans merge into one cluster masked with the widest member's placeholder, and the line is rebuilt from original bytes so no offset is ever applied against a shifted line. The cost is accepted and named: an occurrence the detector deliberately clears — a login inside a URL, including a credentials URL's userinfo — is no longer masked by accident, and the stage-two re-scan does not flag it either; the caller's own home path is not in that residue because the detector flags every occurrence by the same anchor the literal sweep uses.

From 9dd0ed610df23c8556b844997f9c800edeb65706 Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Tue, 15 Sep 2026 16:46:44 +0100 Subject: [PATCH 29/45] feat: a record id written in prose must name a record that exists A spec composed during an autonomous run carried two invented record ids in its body, and nothing in the gates read a record's prose for the handles it names; a human reading the document back afterwards was the detector. The typed cross-references in frontmatter were already resolved, and links were already checked, and between them sat the thing a session actually writes: a sentence. record-lint gains prose_citation_resolves. It reads every record body and every free-text frontmatter field across the record stores, finds each handle in the cited-id grammar, folds the spelling a sentence used into the spelling the resolver keys on, and refuses one that names no record. There is one resolver in this binary and the rule adds no second. A slug does not stop an id being an id, so a filename-shaped handle is a citation of the id it starts with, and a hyphen before the family word does not make it part of a longer handle. An author marks a numeric placeholder or a forward reference on its own line with an illustrative or forward-looking marker, and the refusal message says so. The corpus that predates the gate is carried in a committed baseline keyed on the id, never on the file, since records move between status folders as a matter of routine. Each entry declares which class it is and why: a decision pruned by its successor, an id a predecessor implementation numbered and never minted here, a record living on an unmerged branch, and one probable defect carried as suspect for a human to correct. The baseline ratchets in both directions: a new unresolvable id fails even in a file the baseline names, and an entry nothing cites any more is reported so the list only shrinks. Sixteen existing illustrative sites are marked in place rather than licensed globally by id. Every new behaviour was watched failing first, and the review's findings on slug-continued handles, free-text frontmatter, the leading hyphen and the empty-baseline message were each closed with their own test.

Any literal enumeration of rules in the record belongs in a generated, gated region (an `index_drift`-style marked block that fails when it drifts from the config), never a hand-kept table — a hand-typed catalogue goes stale against the engine's own rules the moment a rule is added. +### 1.1 What `prose_citation_resolves` reads + +The rule reads a record's free text, which is wider than its body and narrower than its bytes.

An intent that has been thought through stands as written: a spec that delivers part of it is closed on its own terms, a new spec is minted for the remainder and attached to the same intent (spec closed X, spec open Y, intent still `planned/`), and the intent moves to `shipped/` on the close after which no open spec names it, with `--impact` demanded at that transition and no earlier.

CI never reads the home list and nothing from it reaches a committed file. Filed as itd-2609151516525843 (`builds_on` itd-74, `refines` adr-56); whether the home is one macOS user's or shared across users stays the product thinker's separate open question.

A slug does not stop an id being an id, so a filename-shaped handle is a citation of its id. The corpus that predates the gate is carried by id, never by file, in `.abcd/prose-citations-baseline.json`, each entry declaring its class and reason, and the baseline ratchets: a new unresolvable id fails even in a file the baseline names, and a spent entry is reported so the list only shrinks.

Measured: 223 mentions, 35 distinct ids, 67 record files. Illustrative ids that exist to describe gate behaviour. Pruned or never-migrated ids narrated historically. Forward references to records not yet minted, one of them a frontmatter field. And a residue of genuine suspects, including one truncated id sitting in a record's own slug.

From bfbafa01c46f50fe189a344c5b4ccba3b166558a Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Tue, 15 Sep 2026 17:05:23 +0100 Subject: [PATCH 30/45] feat: a commit that names an issue declares its relation, and a listing finds the ones it missed Four fixed issues sat open in a managed repository's ledger because the only evidence of their fix was commit prose the ledger never reads. A mention that must declare itself turns that prose into a signal both the gate and the ledger can read. RS004 joins the issue-resolution gate: a commit message, or a pull-request title or body, that names an issue id must carry a declaration line. A resolves line says the change fixes it, and the existing rule then requires the record to move in the same diff; a refs line says touched but not fixed and demands nothing of the ledger. The vocabulary is closed at those two words, a comma-separated list is admitted on either, and a near-miss is refused with the two spellings named. The commit half runs where the existing range check runs; the pull-request form half runs in the attribution workflow, the one that re-runs when a title or body is edited. Merge commits are exempt because the forge composes them. The hint for the backlog that predates the gate is a read-only listing: it walks the default branch and the ledger, and reports each open record whose id appears in a commit message without a resolution, ranked by what the commit did, silent on the commit that filed the record and on a refs declaration. It lists and never moves a record; the test asserts the ledger is untouched. Run here it finds seventy-eight rows and no undeclared resolves line, so the existing rule has held and the backlog is undeclared mentions. Every proof was watched failing first. The review's findings were closed with their own tests: a commit body can no longer forge a record boundary in the walk, since boundaries are checked against the commit graph; a ref that shares a name with a tracked path walks; each row's exemplar is its strongest commit; the shell scanners pin a C locale so a stray byte cannot hide a mention; and the list form on a resolves line is read by both rules, so the declaration that satisfies one cannot bypass the other.

A session met an intent whose criteria were only half delivered, stopped, and asked rather than close, which was right; the rule it was missing is now recorded and built. An intent that has been thought through stands as written. A spec that delivers part of it is closed on its own terms, a new spec is minted for the remainder and attached to the same intent, and the intent moves to shipped on the close after which no open spec names it, with the impact judgement demanded at that transition and no earlier. The spec's back-link is the one source of truth for which specs realise an intent; the intent's own link stays a scalar meaning the spec it was planned with, and the bidirectional check becomes membership. The set is derived by one canonical comparison shared by the spec store, the intent corpus and the record-lint index, because two readers answering "does this intent have an open spec" differently is the exact hole the review found: a zero-padded back-link let the store ship an intent the lint saw as still open, and left the second spec unclosable through any verb. The remainder is minted before any move, so a failure moves nothing, and a retry reuses an open remainder with that slug rather than minting a second. A remainder is refused on a shipped intent or a closed spec. The fidelity audit now names every spec that realised the intent, and the receipt stays owed once per intent. The release cut refuses a planned intent only when all its specs are closed, so a release taken mid-delivery is no longer walled off. Every behaviour was watched failing first, on a scratch copy, and the review's findings each closed with their own test. Eighty-six existing specs and eighty-five linked intents needed no edit. The dispatch pages list an intent's specs only when more than one realises it, so single-spec pages are unchanged.

Both are required, and the two are held differently: `intent_lifecycle` blocks a `superseded/` record whose `superseded_by` is absent or malformed or names an intent no bucket holds, and `record_schema` resolves the handle across stores, while `kind_at_supersession` is **(convention)** — nothing reads it, though every record in `superseded/` carries it. If `kind_at_supersession: bundle-member`, the intent ALSO carries `bundle_at_supersession: <bundle-id>`, preserving the bundle membership at retirement time even though the active `bundle:` field is `null`; that field is convention too. diff --git a/.abcd/development/brief/04-surfaces/README.md b/.abcd/development/brief/04-surfaces/README.md index 8f787f66..160b3a37 100644 --- a/.abcd/development/brief/04-surfaces/README.md +++ b/.abcd/development/brief/04-surfaces/README.md @@ -100,7 +100,7 @@ verb the binary registers apart from the framework's own `help`. |---|---|---| | `changelog` | The deterministic, read-only emit of the next release cut — derived version, record set, guardrail, no prose.

The bootstrap now writes ~/.abcd/cache-attestation (data dir, manifest-authenticated hash, trust, time; 0600; renamed in whole) only after it has authenticated the cache against the release manifest, and install promotes a cache only when the attestation names that directory and the co-located record carries the attested hash. An unbound cache is refused with a note naming which of the three checks failed, and install degrades to the pinned symlink as it does with no cache. An offline bootstrap writes nothing and leaves an existing attestation untouched. The plugin-root stamp route gets the same binding; dogfood checkouts are unaffected because the binding is on the cache, not the plugin-root binary.

The record held three options open for a ruling: + +- **A.** Authenticate at install time against the published `checksums.txt`, + putting a network GET on `ahoy install`. +- **B.** Bind the cache to a record the environment does not choose alone: the + bootstrap, which runs with the harness's real data dir and has just + authenticated the cache against the manifest, writes a home-scoped + attestation, and the PATH promotion accepts a data dir only when it matches. +- **C.** Accept the finding as a documented residual — environment control is + already a PATH foothold — and record it beside adr-46's offline residual. + +The maintainer ruled **B** on 2026-09-15 at an interactive question. A +mechanical partial was rejected in the same record so nobody re-derives it: +cross-checking the recorded hash against the plugin-root binary defeats the +literal recipe only and breaks dogfood installs, because a source checkout used +as the plugin root with a locally built binary never matches the cache. + +An ADR is never amended, always superseded, so this record carries adr-46's +five decisions forward unchanged and adds the sixth. adr-46 is retained rather +than pruned because later records cite its numbered decisions. + +## Decision + +Decisions 1–5 are adr-46's, in force exactly as written there: + +1. **The fetch-time posture carries over verbatim, wherever the download + lands.** Same-origin checksums pinned to one release, the HTTPS pin on every + call, `-q`-first curl with the proxy/CA scrub, and no environment seam for + origins. +2. **Every promotion of a persisted artefact re-verifies against its recorded + `binary_sha256` and refuses loudly on a mismatch.** Cache → plugin root, + cache → PATH copy, PATH-copy refresh, and the migration seed each re-hash + the bytes being moved; a mismatch installs nothing and leaves the evidence. +3. **The cache's own trust is established against the release's published + manifest, not against its co-located record.** Online, the cached digest is + checked against the published `checksums.txt` before the cache is preferred + over a download; offline, the cache is trusted at corruption-evidence only, + and the success notice names which trust it rests on. +4. **Ownership is recorded provenance, never content-guessing**, and the record + lives in a home-scoped, abcd-owned location reachable without any harness + variable, because the verbs that consult it run from a terminal. +5. **SessionEnd performs no network work.** + +6. **The cache reaches PATH only through a home-scoped attestation the + environment cannot write.** The bootstrap — the one process that holds the + harness's real data dir and has just established manifest trust for the + bytes in the cache, whether by authenticating a cache hit or by verifying a + fresh download against the same-origin manifest — writes + `~/.abcd/cache-attestation`, a sibling of `path-entry` in the same key=value + form: `data_dir`, the manifest-authenticated `binary_sha256`, `cache_trust` + (the bootstrap's own vocabulary; only `manifest` is ever written), and + `attested_at`. It is written whole into a sibling temp file and renamed in, + mode 0600, after the root install's own re-hash succeeded, and only on + manifest trust: an offline run, which proved corruption evidence and nothing + more, neither creates nor rewrites it, and a run that could not authenticate + leaves any existing attestation exactly as it found it. `ahoy install` + promotes a cache into the owned PATH copy only when three things agree — + the attestation names the directory being promoted from, the co-located + `binary-meta` carries the attested hash, and the artefact hashes to it + (decision 2) — whichever route named the directory, the hook's environment + variable or the plugin root's `.data-dir` stamp. Either route is a route and + neither is trust. A present cache the attestation does not bind is refused + with a note that names which of the three failed, in tilde paths only, and + the install degrades to the pinned symlink exactly as it does with no cache + at all; detection offers the owned-copy heal on the same predicate, so the + two surfaces never disagree about one directory. The attestation binds the + **cache**, never the plugin-root binary: a source checkout as the plugin + root with a locally built binary is untouched. + + The trust floor for this promotion moves from "a value the environment + supplies" to "a write into the caller's own home" — the same floor decision + 4 already sets for ownership. An attacker who can write `~/.abcd` already + owns `path-entry` and everything it vouches for, so the attestation grants + nothing that authority did not already hold; an attacker who can only set + the environment, including through a committed project settings file's + environment block should a harness honour one, reaches the data dir and + nothing in the home. + +## Alternatives Considered + +- **A. Authenticate at install time against the published manifest.** + Rejected by the ruling: it puts a network GET on a verb the brief documents + as disk-only (adr-38), so offline it must either degrade to the symlink + fallback anyway or invent a second trust vocabulary; it also re-fetches what + the bootstrap has already fetched and proved in the same session. +- **C. Accept as a documented residual.** Rejected by the ruling: "environment + control is already a PATH foothold" is weaker than it reads, because a + harness that honours a committed project settings file's environment block + lets a hostile checkout set the variable for its own sessions, and the + owned-copy claim is what the hook shims trust before running an `abcd` off + PATH — a foothold that is also a vouched-for binary is not a residual of the + same size. +- **Cross-check the recorded hash against the plugin-root binary.** Rejected + as a mechanical partial: it defeats the literal reproduction and breaks + dogfood installs, whose plugin-root binary is a local build the cache never + matches. The attestation binds the cache, not the root, for this reason. +- **A terminal route to the cache through the attestation alone** (when the + environment is unset and the root's stamp is missing). Not adopted, although + it falls out of the same record: it would turn a dogfood checkout's stable + symlink into a `symlink.legacy` gap healed to a release copy on the next + `ahoy install`, which is the behaviour change the rejected partial was + refused for. The stamp remains the terminal's route; the attestation binds + whatever the stamp names. +- **Extend `path-entry` with the attestation's fields** instead of a sibling + record. Rejected: `path-entry` records exactly one thing, the owned copy, + and is parsed by the hook shims on every PATH resolution; the attestation + describes the cache, is written by a different process at a different time, + and must survive an uninstall that removes `path-entry`.

The reviews found the expensive parts unsound as drafted: a `claimed_by` stamp on an issue record is invisible to any peer on an older binary, because `issueschema.Known` is a closed allow-list whose reader refuses and skips a record carrying an unknown key and `record_schema` mirrors the refusal into the gate, and version skew is the steady state here (five plugin-cache vintages beside a `go run` checkout); the write-verb refusals fire after the fix is written, because `AGENTS.md` puts `capture resolve` in the same change as the fix; no staleness threshold is safe in both directions for two sessions in one worktree, since the worktree-exists and branch-merged tests are identical for both and a host may fire session-end on a context clear with the human still present; and the pushed half costs a merge-queue pass per claim, measured at fifteen to sixteen minutes on this repository's merge-group `ci` leg. Every collision on record is one of two claim-free shapes. The ruling: itd-2609091416295622 carries the read-only sibling-worktree ledger diff over `git worktree list --porcelain` (no claim, no lease, no hook, no threshold; the piece that ships soonest); itd-2609091416304128 carries `capture resolve` and `capture wontfix` refusing a record terminal at the local `origin/main` ref as last fetched, stating the ref's age and fetching nothing, with the same judgement rendered read-only on `abcd <record-id>`; itd-2609091034175565 keeps the claim, the lease and the refusals as a draft marked not ready, carrying the refusal-surface, liveness and pushed-price questions as open questions and the two-release stamp migration as a hard constraint. The existing record stays the claim so the `promoted_from` trail from iss-2609020716570699 — whose remedy is the claim and the pushed half — stays true rather than being retitled onto a listing the issue never proposed; the two new records reach the issue through `related_intents` on the issue and on themselves, and every relation the schema cannot type is stated in prose as a prose cross-reference (iss-2609091256264547).

(1) The status-line offer is its own consent category, `status-line`, advisory and never approved by `--yes`, exactly as the git-identity pin is: it rewrites a harness-wide user setting and takes element choices, so only an answered prompt writes it, and `yes |` answers it. A decline is never persisted; the offer returns on the next install until the user-level setting exists. (2) Harness detection is positive evidence only: the harness's user settings file exists and parses (its directory from `$CLAUDE_CONFIG_DIR`, else the harness home); no file means nothing offered and nothing written. Ownership of a status command is decided by shape (`<absolute entry with leaf abcd> statusline`), which is what makes a dangling entry decidable when the binary is gone. (3) The two record counts on the row are FOLDER counts (files named `iss-*.md` in the open ledger; `itd-*.md` in drafts plus planned), not the board's parsing readers, because the verb runs on every status refresh and a parse over a clone-controlled record measured 0.96 s at twenty thousand records; folder membership is the record's own status signal, so the number differs only where a parser would skip an unreadable record. The spec's Scope text is corrected to say so. (4) Two guards the reviews required and the spec did not name: the previous-command fallback refuses to run when its own marker is already in the environment and marks its child, so a recorded command that reaches `abcd statusline` in any spelling terminates instead of forking without bound, and the install refuses to record such a command at all; and every write to the harness settings re-reads the file immediately before the act and merges into the fresh document, refusing when the status-line key changed under the prompts (itd-193's rule applied to a user file a live harness also writes). (5) `abcd mode <state>` prints the owed-answer line only when the user-level setting is absent or disabled — the setting is the only evidence of a status surface abcd has — and `managed` prints nothing; the bare board renders the presence line even when the line is disabled, because the switch silences the line and the board is the fallback. Rejected: making the offer a config-change gap (one consent for the PATH entry and the status line would let the reason paragraph be skipped); counting through the board's readers with a cache (a second mechanism to keep correct for the cheapest surface in the tree). The fidelity audit rcp-636b39d5541a records five criteria met with concerns, all disclosed on the shipped record; the one the record could close is closed: the GRILL rule domain now tells an agent to set the mode before it stops for a verdict. - 2026-09-15 — The roles and loopback design workstream lands on main, executing the 2026-09-01 ruling that the branch waits for the mint verb and takes its ids at the merge. `abcd decide` now exists, so the two decisions the branch numbered 0055 and 0056 are re-minted as adr-2609151528057260 (three roles, who each artefact addresses, and when the loop stops) and adr-2609151528057131 (abcd owns the product thinker's surface), content, status and date unchanged; every citation that meant the roles decisions is re-pointed (rfc-3, the phase-8 page, the roles page, the out-of-scope list, three intent drafts, and iss-168, whose 29 August extension cited them by the colliding numbers), and main's own 0055 and 0056 keep their ids. The branch's twelve hand-numbered intent drafts (itd-165 to itd-176) collide with nothing and keep their ids, as adr-45's grandfathering allows. Occasion: itd-200 shipped today refining the two roles decisions, so their citations on main pointed at the wrong records until this landed. +- 2026-09-15 — GHSA-4q78-ccfv-f374 (iss-2609012039102770) is closed by OPTION B, ruled by the maintainer at an interactive question: bind the cache to a record the environment does not choose alone. The owned PATH-copy promotion re-verified the cache only against the `binary-meta` beside it, and `CLAUDE_PLUGIN_DATA` is taken from the environment as given, so whoever chose the directory wrote both the bytes and the record that "verified" them — reproduced at v0.7.0 as a one-byte file installed 0755 as `~/.local/bin/abcd` with provenance recorded. Now the bootstrap, the one process holding the harness's real data dir that has just established manifest trust for the cache (an authenticated cache hit, or a fresh download verified against the same-origin manifest), writes `~/.abcd/cache-attestation` — `data_dir`, the manifest-authenticated `binary_sha256`, `cache_trust=manifest`, `attested_at`; 0600, temp-and-rename, beside `path-entry` — and `ahoy install` promotes a cache only when that record names the directory, the co-located record carries the attested hash, and the artefact hashes to it, whichever route (environment or the root's `.data-dir` stamp) named the directory; detection offers the heal on the same predicate. An offline run neither writes nor rewrites the attestation, so a cache provisioned offline waits for a networked session before it reaches PATH, said out loud. Why B: the trust floor moves from a value the environment supplies to a write into the caller's own home, which adr-46 decision 4 already treats as the ownership root, so the attestation grants nothing that authority did not hold and costs `ahoy install` no network (adr-38 stands). Rejected: A (a manifest GET on a disk-only verb, re-fetching what the session already proved); C (a documented residual — weaker than it reads, since a harness honouring a committed settings file's environment block lets a hostile checkout set the variable, and the owned-copy claim is what the hook shims trust); the mechanical partial of cross-checking against the plugin-root binary (breaks dogfood installs whose root binary is a local build); and a terminal rung through the attestation alone (it would heal a dogfood checkout's stable symlink into a release copy). adr-46 is superseded by adr-2609151706587280 (never amended, always superseded; retained because its numbered decisions are cited), spc-35 Design 2 step 1 and Design 3 are revised in place and dated, and brief invariant 12 gains the clause. diff --git a/.abcd/work/issues/open/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md b/.abcd/work/issues/resolved/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md similarity index 64% rename from .abcd/work/issues/open/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md rename to .abcd/work/issues/resolved/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md index 17c34141..d1085a19 100644 --- a/.abcd/work/issues/open/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md +++ b/.abcd/work/issues/resolved/iss-2609012039102770-ghsa-4q78-owned-copy-verification-self-referential-under-env-data-dir.md @@ -9,6 +9,8 @@ found_during: "autonomous-run-2026-09-01" origin: researcher-authored production_mode: hand-written found_at: "internal/core/ahoy/owned_copy.go" +resolution: "Option B, ruled by the maintainer on 2026-09-15 at an interactive question: the bootstrap, which runs with the harness's real data dir and has just authenticated the cache against the published release manifest, writes a home-scoped attestation (~/.abcd/cache-attestation: data_dir, the manifest-authenticated binary_sha256, cache_trust=manifest, attested_at; 0600, atomic, beside path-entry) and only on manifest trust — an offline run neither writes nor rewrites it. installOwnedEntry promotes a cache only when the attestation names that directory, the co-located binary-meta carries the attested hash, and the artefact hashes to it; an env data dir with no attestation or a mismatching one is refused loudly (tilde paths only) and install degrades to the pinned symlink exactly as with no cache.

A test seam (nil in production) occupies the window deterministically; TestInstallRefusesPairFlippedAfterBinding was watched failing with the forged pair promoted and no note, and passes with the pair refused on the checksum, no PATH entry and no provenance written.

Four prose-citation baseline entries carried ids that lived only on the design branch; the branch has landed and they resolve, so the ratchet's shrink half reported them spent and they go. One id written on main as an example of the minted id shape takes the rule's illustrative marker on its line. Three decision records and one intent linked issue records by their open path, which the resolutions of this cycle moved; the links now name the resolved path.

Each is answered on its own terms rather than waved through. Two are resolved on evidence. The roles page rewrite that landed today answers every complaint the README-and-roles-page finding made, except one phrase a later merge had silently dropped from the README, which is restored here. The finding that the conventions file still told authors ADRs keep a hand-numbered ordinal was fixed three days ago under its twin record, and is closed against that commit with an internal impact so one correction does not become two changelog lines. Six are deferred out loud, each with its own reason on the record. Four of the design workstream's findings about the fidelity audit, verification rungs and responsibility for delivered work are settled by decisions the workstream itself filed as drafts and an open request for comment, so building them now would answer in code the question the record routes to the product thinker. The finding that auto-release tags before the gate that can refuse it is renewed at this anchor with what changed since its first waiver: a second run falsified the premise the earlier ruling rested on, so the remedy is now the completion of an accepted ruling, wanted at the top of a cycle rather than at the end of one. The slug generator's trailing hyphen does not reproduce: every truncation site already trims the separator, two hundred thousand adversarial inputs produced no refused slug, and what remains of the record is a vocabulary ruling.

The ingest does not branch on the verdict value: it rolls the per-criterion verdicts into counts and replaces the parked OWED marker with INGESTED whatever they say, so a verdict of all-INCONCLUSIVE closes the receipt exactly as a verdict of all-MET does. The re-emit verb then refuses to reopen it, reporting already_ingested and leaving the Audit Notes untouched, which is correct for a decided audit and wrong for an undecided one. The consequence is that there is no way to ensure the re-run that an INCONCLUSIVE calls for. The only lever that produces a fresh receipt is editing the acceptance-criteria section, because the receipt digest is taken over that section alone, which conflates two unrelated acts: clarifying a promise, and retrying an audit that was merely under-fed. This is a loud-staging violation in the precise sense the principle names, since a stage that degraded presents as a completed one. The narrow fix is for the ingest to branch: an INCONCLUSIVE leaves the receipt OWED, or moves it to a distinct re-run state, so the outstanding work stays visible without minting a ledger issue for what is an input fault rather than a product defect. diff --git a/.abcd/work/issues/open/iss-2608290822140563-the-fidelity-audit-runs-after-the-merge-so-its-verdict-arriv.md b/.abcd/work/issues/open/iss-2608290822140563-the-fidelity-audit-runs-after-the-merge-so-its-verdict-arriv.md index b6ec5ffc..0269684f 100644 --- a/.abcd/work/issues/open/iss-2608290822140563-the-fidelity-audit-runs-after-the-merge-so-its-verdict-arriv.md +++ b/.abcd/work/issues/open/iss-2608290822140563-the-fidelity-audit-runs-after-the-merge-so-its-verdict-arriv.md @@ -7,6 +7,8 @@ category: "process" source: "user-observation" found_during: "intent-implementation-run" found_at: "internal/core/intent/audit.go" +deferred_after: "v0.8.0" +deferral_reason: "The direction is decided, the work is not filed, and the ordering cannot move on its own.

Moving it means changing the ship path itself, since the ingest refuses any intent not already in shipped and the emit fires from the ship move, and it means building the post-merge content-hash check that answers the branch-is-not-the-landed-tree objection this record raises against itself. itd-165 states the sequencing constraint in its own words: the ratchet that would let a verdict block anything is held back deliberately, because there is no corpus of real verdicts yet and a ratchet baselines whatever number it finds. A pre-merge gate built today would be tuned against nothing. Waits on itd-165 being planned and producing that corpus, and on an intent filed for the reorder once it has." --- The fidelity audit runs after the merge, so its verdict arrives when the cheap remedies are already gone, and the code refuses any other ordering: the ingest rejects an intent that is not in the shipped bucket, and the emit fires from the ship move itself, so an intent cannot be audited against the candidate diff on a branch. The stated reason is sound as far as it goes, that a report-only review must never un-ship what has already shipped, but it answers a question that only arises because the audit was placed after the merge in the first place. Audited before the merge, a failing criterion has three cheap answers: fix the branch, revise the promise before making it, or decline to merge. Audited after, it has none, because there is no un-ship path and the code is on the trunk. The counter-argument is real and should not be waved away: a branch is not the tree that lands, since the merge queue lands merge commits and a semantic conflict with a concurrently merging change can alter the delivered reality after the verdict was formed, so the post-merge audit judges what is actually true while a pre-merge one judges a candidate. The shape that gets both is to gate on the pre-merge verdict and bind it to a content hash of the tree it judged, then check deterministically after the merge that the landed content still matches, reopening the receipt only on a mismatch, which costs one hash comparison rather than a second audit and reuses the content-addressing the transcript store already relies on. Whatever the ordering, the model's verdict must stay a proposal and a human acknowledgement must remain the gate, because a non-deterministic verdict that can block a merge on its own is a trust step this repository has not taken and would train people to route around the gate. diff --git a/.abcd/work/issues/open/iss-2608290944122400-efficiency-pressure-is-the-defeater-this-framework-has-no-an.md b/.abcd/work/issues/open/iss-2608290944122400-efficiency-pressure-is-the-defeater-this-framework-has-no-an.md index 8006aa89..8cc93cdd 100644 --- a/.abcd/work/issues/open/iss-2608290944122400-efficiency-pressure-is-the-defeater-this-framework-has-no-an.md +++ b/.abcd/work/issues/open/iss-2608290944122400-efficiency-pressure-is-the-defeater-this-framework-has-no-an.md @@ -7,6 +7,8 @@ category: "process" source: "user-observation" found_during: "role-clarification-run" found_at: ".abcd/development/roadmap/rfcs" +deferred_after: "v0.8.0" +deferral_reason: "This finding is the open question of an open RFC, and it is settled by a decision rather than by code. rfc-3 cites this record by id and calls its question the one that RFC most needs answered: whether the chosen rung must be visible in what abcd produces, so that shipping on the cheapest one is a stated position rather than a silent default.

Tested against this framework the first is partly answered and the second is answered well, since the product thinker sets the acceptance criteria, owns the register they are addressed in, chooses the verification rung, and configures the facilitator, which is real authority over the things that determine the outcome rather than a veto at the end. The third is unanswered. Climbing the verification ladder costs money, time, and subscriptions, and nothing in the design resists the pull towards the cheapest rung. For a solo builder the organisation exerting that pressure is the builder, which makes the pressure harder to notice rather than weaker. Worth deciding whether the framework should make the chosen rung visible in what it produces, so that shipping on the cheapest rung is a stated position rather than a silent default, and whether a project whose blast radius reaches strangers should have to say so out loud before the ladder can be lowered. Note also that the same framing arrives independently at the escalation ladder, calling it tiered routing where higher-stakes cases go to humans and lower-stakes ones to automation, which is convergent evidence for that design rather than a new idea. \ No newline at end of file diff --git a/.abcd/work/issues/open/iss-2608290956522870-responsibility-for-delivered-work-has-no-home-in-the-record.md b/.abcd/work/issues/open/iss-2608290956522870-responsibility-for-delivered-work-has-no-home-in-the-record.md index 8d0f5cb5..8f3c497d 100644 --- a/.abcd/work/issues/open/iss-2608290956522870-responsibility-for-delivered-work-has-no-home-in-the-record.md +++ b/.abcd/work/issues/open/iss-2608290956522870-responsibility-for-delivered-work-has-no-home-in-the-record.md @@ -7,6 +7,8 @@ category: "process" source: "user-observation" found_during: "role-clarification-run" found_at: "scripts/check-attribution.sh" +deferred_after: "v0.8.0" +deferral_reason: "The shape is agreed; what it would mean is not.

The convention names an assisting tool, which is disclosure and deliberately not authorship, and nothing anywhere records the act that actually carries responsibility: a named person accepting a delivered promise as matching what they asked for. Adding a co-authorship trailer for the tool is the wrong repair and this repository already refuses it, since it asserts an authorship a tool cannot hold and inflates the contributor graph, and the largest project to deliberate the question chose the assisting form over the co-developed one for exactly that reason. The right shape is a separate acceptance trailer naming the human who accepted delivery, which only a person can sign, so an automated facilitator structurally cannot. It belongs on the intent rather than on a commit, because what is accepted is a delivered promise and not a diff, with a mirror on the merge commit if a commit-level trace is wanted. It should carry the verification rung alongside the name, because an acceptance is worth exactly as much as the checking behind it and an acceptance on the cheapest automatic check should not read identically to one that followed an outside audit. diff --git a/.abcd/work/issues/open/iss-2609100513521322-auto-release-cuts-the-tag-before-the-gate-that-can-refuse-it.md b/.abcd/work/issues/open/iss-2609100513521322-auto-release-cuts-the-tag-before-the-gate-that-can-refuse-it.md index 42da4b23..2c28e598 100644 --- a/.abcd/work/issues/open/iss-2609100513521322-auto-release-cuts-the-tag-before-the-gate-that-can-refuse-it.md +++ b/.abcd/work/issues/open/iss-2609100513521322-auto-release-cuts-the-tag-before-the-gate-that-can-refuse-it.md @@ -9,8 +9,8 @@ found_during: "v0.8.0 release, runs 34403815697" origin: researcher-authored production_mode: hand-written found_at: ".github/workflows/auto-release.yml" -deferred_after: "v0.7.1" -deferral_reason: "Found while cutting v0.8.0, and the remedy changes the release pipeline itself, which is not a thing to reorder underneath a release that is mid-flight.

Three claims outrun the code. The README says the records are checked by gates that refuse rather than warn, but the lint engine carries a warn severity and uses it: this run's own preflight emitted a warn-level finding and a docs-lint line reading one finding and zero blockers, so an advisory tier exists by design and the sentence denies it. The README then says what these records claim about the product being built stays true as the product moves, but the only mechanism that could make that true is the intent-fidelity audit, and that audit is report-only by construction, refuses to run against anything but an already-shipped intent, cannot be re-run once an inconclusive verdict is ingested, and is read by no gate. Empirically the claim is false today: twelve intents describe capabilities that are on the trunk, not one has been audited, and twelve specifications sit open while the code realising them has shipped, with nothing detecting the drift. The roles page goes further than the README and promises the product thinker a moment of reading the verdict on whether the why was delivered, and promises the facilitator will say what to do about a mismatch, when no verdict has ever been produced and no remedy path for a failed criterion exists. The README also flattens the three roles into agents and humans, which contradicts the roles page it links to and is the same conflation that makes it easy to argue a facilitator duty must stay manual because it is a human decision. The honest rewrite keeps the ambition and stages it: most gates refuse, the fidelity judgement is recorded rather than enforced today, and the sentence about product truth is stated as what the audit is for rather than what is already guaranteed. Widened 2026-08-29 by the role frame. Beyond the two claims already corrected in the README, the roles page carries four further over-promises and two under-promises: it promises the product thinker a verdict whose form is engineer-readable; it promises the facilitator will say what to do about a mismatch, where no remedy path exists; it asserts the product thinker's trade-off judgement is decisive while nothing routes a trade-off to them; and it frames a two-human team as the design with automation as an aim, where the facilitator is a machine by default and a person on activation. It omits the third product-thinker moment, validating the product in use, and it names no role for the agent team at all.

The attestation was read through the guarded read alone, while the path entry it stands before is read through the declaration read, which additionally refuses a record writable by group or other or owned by another uid. The attestation chooses the directory and the hash a release binary is promoted against, so a record anyone else could write was a record anyone else could aim. It now clears the same three-part bar, and the comment that claimed it already did is replaced with what the declaration read adds and why. The fix's safety argument also assumed the home directory is not something the environment can choose, and neither reader nor the shell writer pinned it: a relative home resolved against the checkout, so a committed record under it would have been read as the user's own. Both readers and the bootstrap now refuse a home that is unset, not absolute, or inside the repository being installed, through the one containment helper the data directory hazard already uses. A refused home is named as the reason, the install's remedy matches it instead of pointing at network access, and the bootstrap says why it wrote no record rather than saying nothing. The containment compare reads the real working directory, never the environment's word about it, which the existing origin-allowlist test enforces from the other side. One finding is captured rather than fixed: a stale attestation permits a downgrade to the last attested genuine release, bounded to a manifest-verified binary, since the record carries no freshness. Every behaviour was watched failing first on a scratch copy; the live home was never touched.

(itd-2609090559376002, iss-2609081917287384) +- **`abcd history ingest --into <repo>` recovers transcripts already on disk into the repository that owns them**, redacted under that repository's own rules: the destination is an operand with no default, a transcript whose owner cannot be established is skipped and named rather than filed by guess, and `abcd history migrate` repairs the records filed under a composite session id. (itd-2609091718566731) +- **`abcd history reconstruct <session-id>` renders one whole session — the main thread and every sub-agent it spawned — as a single self-contained artefact**, beside a telemetry file reporting span, turns, tokens, tool calls, models and agent types per session and per agent, and stating its own gaps. (itd-2609091718595846) +- `abcd history list --session <id>` returns a session's whole set, main thread first, and the human listing and `history show` carry the agent, its type, its parent and its depth, so a session's sub-agents are reachable from the session identifier without filtering machine-readable output by hand. (iss-2609091915475296) +- Staged raw transcripts stop living indefinitely: a small drain runs while a session is live, an overdue entry sorts to the front of every drain and is named in the notices, a session start surveys every repository in the store for a backlog, and a transcript that redaction deterministically refuses is quarantined with its reason instead of being re-read on every pass. (iss-2609090722466403) +- **A managed repository shows it is managed, and says whose answer the agent loop is waiting on.** `abcd statusline` leads the host's status line with one badge in three states — abcd is here and nobody is waiting, waiting on the facilitator, waiting on the product thinker — `abcd mode` sets the state, the install step offers and wires the line as its own consent category, and an unmanaged repository shows nothing. (itd-200, iss-168, iss-2608210934566225) +- **An intent owns one or more specs, and ships when its last spec closes.** `abcd spec close --remainder <slug>` mints the follow-on spec against the same intent, which stays planned. What stops working: closing a spec no longer ships its intent on its own, so a partially delivered intent reaches `shipped/` only at the close after which no open spec names it, and `--impact` is accepted at that close alone. (iss-2609100508566552) +- **A refusal in machine-readable mode answers on standard output**, in an envelope that announces itself with a top-level key no success envelope carries and states the exit status inside the document, so a consumer that merges the two streams can still tell a refusal from a result. What stops working: two verbs that render and then fail now put two documents on standard output where they put one on each stream, the refusal always last, so a consumer assuming exactly one document there must read to the end. (iss-2609100519128005) +- A refused flag value names the set it would have accepted: all three closed enumerations render their accepted values from the one schema when they refuse, and two of the three flags gained that set in their help as the third always had. (iss-2609100519128005) +- A commit message, pull-request title or pull-request body naming an `iss-N` must declare `Resolves:` or `Refs:` — RS004 refuses one that does not — and `abcd capture mentions` lists, read-only, the open issues named by default-branch history with no resolution behind them. (iss-2609100507421759) +- A record id written in a record's prose must name a record that exists: `record-lint` refuses an id that resolves to nothing, with a line-scoped illustrative or forward-looking marker as the escape and an id-keyed baseline carrying the corpus that predates the gate. (iss-2609100518527863) +- `abcd lint outbound` judges one piece of outbound text — a commit message, a pull-request body, a release note — against the outbound policy, refusing a live agent-session URL or a tool's attribution footer and masking the matched span in its report; it reports and refuses without rewriting the text, and is what CI runs over every commit message in a pull request's range and over the body. (iss-2609152131205316) + +### Fixed + +- **GHSA-4q78-ccfv-f374**: a plugin cache the environment names is promoted to the owned copy on PATH only when a home-scoped attestation — written by the bootstrap after authenticating the cache against the published release manifest — names that directory and the artefact hashes to the attested value; an absent or mismatching attestation is refused loudly and the install degrades to the pinned symlink. (iss-2609012039102770) +- The declaration naming which binary the hook shims may execute is honoured only when this session owns it and nobody else can write it: a symlinked, group- or world-writable, or foreign-owned record is ignored by the readers and by all five shims, which take their existing loud refusal instead of executing a binary another local account chose. (iss-2609091927085132) +- A reverse-DNS identifier or module path whose first component happens to equal the account name survives capture intact: a bare-username match is suppressed only where it is a whole component of a dotted run of at least three, while a bare mention, a two-part filename and an email local part still redact. (iss-2609100505142469) +- Identity redaction rewrites exactly the byte spans the detector flagged, so a line carrying both a genuine mention and a lookalike keeps the lookalike byte for byte instead of having it masked as well. (iss-2609120446083912) +- A transcript ingest refuses a destination whose repository root and store key name two different repositories, so one repository's redaction configuration can never govern another's corpus; a root whose own root commit does not resolve refuses rather than passes. (iss-2609091911060345) +- Nothing quoted from a session can begin a line of the reconstruction artefact: every scalar written outside a fence goes through one line cleaner, is placed in a code span whose delimiter outruns any backtick inside it, and is pipe-escaped in the timeline table, so the document's structure is the document's own. (iss-2609091913570877) +- The refusals that protect a write from a degraded secret scanner are armed by tests rather than merely present: transcript capture, the composite-id repair and the memory store's write side each prove they refuse instead of storing under weakened redaction, and the sweep armed every other such site bar the two that are report-only by design. (iss-2609091915350221) +- A sub-agent transcript is placed by its session before its own recorded directory, so an agent whose isolated worktree was removed when it stopped is filed under the repository that owns it instead of being orphaned. (iss-2609090723023943) +- Transcript telemetry counts one usage per response rather than per transcript line, so a response written as several content blocks is counted once instead of inflating a session's reported cost by a factor that varies from session to session. (iss-2609090723027424) +- The privacy-hygiene lint stops firing on the two shapes the conventions themselves mandate — a persona home path from the committed registry, and anything beneath a shared system root — while a non-roster username, a persona used as a prefix or suffix, a lookalike directory, a traversal escape and the committing user's own name all still fail. (iss-2609100505145554) +- Deleting a blocking finding no longer clears the release gate: a record the anchor held open and that is absent from the whole ledger at HEAD refuses the cut by name and grade, while a resolution, a wontfix, a re-slug and a standing deferral each go on clearing it. (iss-2609091143455568) +- An id claimed by more than one record file is refused by every read of the ledger, naming both paths, so a merge that leaves a record in two status folders can no longer read as open and resolved at the same time. (iss-2609100507430423) +- A link on PATH that resolves to nothing is cleared by the install step instead of walling it for ever, while a link that resolves to a file is somebody's working install and is still refused untouched. (iss-2609100506256636) +- A repository whose artefact is not a plugin can use the release flow: an absent plugin manifest reads as absence rather than an unreadable payload, so the derived changelog, the payload scan and the release gates run, while a manifest that is present and unreadable or malformed still refuses. (iss-2609100506255436) +- An intent-fidelity request carries host-computed rubric and prompt hashes and the ingest verifies them rather than shape-checking them, so an audit note can no longer record provenance the host never issued; a hash the host did not issue is refused outright and the owed review stays open. (iss-2609100505140261) +- `abcd spec close --impact` stamps the product impact on an intent that declares none, validates one already recorded at the same bar and refuses a flag that disagrees with the record, so the missing field is answered in the same command instead of sending the operator back to edit frontmatter by hand. (iss-2609100518522943) +- A mistyped `intent` sub-verb is refused with the registered sub-verbs named and nothing created, instead of being filed as a draft intent: a whitespace-free token followed by a record id is judged a subcommand call, while genuine prose of two or more words still files. (iss-2609100508562701) +- `abcd decide` mints a decision record through the same collision-proof allocator every other record family uses, so a repository whose own records tell an author to run it can be followed literally instead of hand-minting an ADR by copying a neighbouring file's shape. (iss-2609100507432904) +- The ledger's human gates report rather than refuse where the language they ask for is not yet settled: `intent ready` keeps its seven rows and gates on four, `capture promote` and `capture resolve` record grounds only when given, and a lapse capture with no instant records none. (iss-2609091009111294) +- The README and the roles page name the same three roles and state the intent-fidelity judgement as recorded rather than enforced, so the front door stops claiming as achieved what is still the design intention. (iss-2608290833558547) + ## [0.8.0] - 2026-09-09 These notes list what was added and what was fixed; changes to earlier behaviour are not claimed until the composer can see the previous release. From 8c4fc71ec162fcda47dcaf434b3b67e8dac367af Mon Sep 17 00:00:00 2001 From: REPPL <77722411+REPPL@users.noreply.github.com> Date: Tue, 15 Sep 2026 22:55:54 +0100 Subject: [PATCH 43/45] chore: record the v0.9.0 semantic gate receipts for dca2d779 Both host-run gates PROMOTE at full tier, which a breaking release requires. A receipt names the commit its reviewers read and cannot sit in that commit's tree, so this is the last commit of the release branch and dca2d779 is the content it attests. docs-currency-reviewer read the user-facing surface against a binary built from the first roll of the section: every line verified against the code with file and line evidence, and every user-facing page changed since v0.8.0 found current. Its three findings were all incomplete rather than false, and all three were fixed before the section was re-rolled: a shipped verb with no record and therefore no line, which is now recorded and named; the README's sample board, which now shows its presence line; and the mode page, which now says where the print form refuses. The receipt says exactly how the commit it names differs from the one read. The brief-surface crosscheck ran its 37 pinned checkers at full tier, five at a time, and returned 115 discrepancies, all dispositioned. Every one is design-record prose that ships in no binary; forty-three describe surfaces this cycle shipped whose brief chapter was not brought up with them, the rest were already divergent at the last release. Four armings have now returned 246, 137, 109 and 115, a fresh sample each time, so the systematic brief pass already recorded is the remedy and the receipt says so per finding.

This is a PATCH in the 0.x band: the verdict shape, the rubrics and every other ingest rule are untouched. The local gate runs unarmed, which is why preflight did not see it.
