 # Changelog
 
+## [1.91.270.0] - 2026-10-27
+
+### Added
+- **Repositories without a version source** (`ship/SKILL.md` Step 12, `ship/sections/changelog.md`, `gstack-ship-receipt write`): a repo with no `.gstack/version-path` pin and no `VERSION` ships without a version change: `Version bump: skipped (no version source: <path, reason>)`, no `VERSION` is ever created, the PR title is unprefixed and the run log records `"version":null`; the receipt records `"version": "none"` when the repo also has no `package.json#version`, no policy stamp file and no CHANGELOG. A repo with no CHANGELOG (the policy's `changelog` is null or the file is absent) prints `CHANGELOG: skipped (none at <path>)` and never creates the file ([ship-policy.md#ship-receipt](docs/ship-policy.md#ship-receipt)).
+- **Docs audit record and doc caps** (`lib/ship-receipt-docs.ts`, `gstack-ship-receipt write --docs <json|@file>`, `gstack-ship-receipt docs-caps [--base <ref>] [--policy <file>]`, policy key `docs.caps: [{ path, max_bytes }]`): Step 14.5's outcome (`updated` | `current` | `blocked`, with the owner's `exception: { accepted_by, date, via, reason }`) is part of the receipt; `blocked` without an exception, or a `--body` that lacks the exception line word for word, refuses with `DOCS_AUDIT_BLOCKED`; a declared doc over its byte cap (or absent) prints `DOCS_CAP: <path> <bytes>/<max> over` and blocks before the verification gate; the caps come from `origin/<base>`'s policy, never the branch's copy, so a PR cannot raise its own cap, and an unreadable base policy refuses with `POLICY_SOURCE_UNAVAILABLE` (`--policy <file>` is for a repository bootstrapping its policy). The `docs` key needs `min_gstack_version` (`DOCS_CAPS_KEY_VERSION`, the release that stamps this entry).
+- **`docs/unattended.md#ship-evidence`**: what an unattended /ship leaves for a parent: the READY evidence through `gstack-ship-receipt result`, the `review_loop` counters, the cross-family Capy subagent as the Step 11 outside voice with its review-log row, and the `CARRY:` lines.
+- **Paid case `ship-frozen-scope-convergence`** (behavior, gate; `test/helpers/ship-frozen-scope-actor.ts`, `test/skill-e2e-ship-frozen-scope.test.ts`): the native actor runs the generated Step 9.4 and its repeat decision under `review_scope: frozen` against a fixture with one CRITICAL in the diff and one in untouched code; the contract is the in-diff fix committed, the pre-existing file byte-identical and deferred, pass 2 on the range only, exit through decision 4 and `REVIEW_LOOP: passes=2 blocking_found=2 deferred=1 fixed=1`. First panel 3/3 at $0.66.
+- **`gstack-ship-receipt read --check-prose`** (`lib/ship-receipt-prose.ts`): every counter the PR body quotes (`passes=2`, `1 deferred`, `passed: 41`) is compared with the receipt's `review_loop`, `gate` and `ci` integers; a disagreement is `RECEIPT_PROSE_MISMATCH` (exit 1) with a `PROSE:` line naming each field and both values.
+- **`review/checklist.md` rules with ids**: `prereg-with-results` (Pass 1, Gate Integrity, ASK: a preregistration and its results in one diff) and `test-keyboard-count-loop` (Pass 2: a browser test that reaches an element by a counted loop of key presses).
+- **`bin/gstack-coauthor-trailers`**: the `Co-authored-by` trailers a ported range owes (distinct authors other than the checkout's committer, first-appearance order; `--message <file>` adds the missing ones to the file's trailer block through `git interpret-trailers` with pinned placement, idempotently, so an existing co-author keeps attribution; a `--base` or range starting with `-` is a usage refusal and a slash-named default branch resolves through `origin/`), for porting a contributor's PR with their authorship kept ([review-policy.md#porting-a-contributors-work](docs/review-policy.md#porting-a-contributors-work)).
+- **Result codes** `DOCS_AUDIT_BLOCKED`, `RECEIPT_GIT_TOO_OLD`, `RECEIPT_PROSE_MISMATCH` (`lib/result-codes-release.ts`, `docs/troubleshooting.md`).
+
+### Changed
+- **`gstack-ship-receipt carry`**: needs git 2.39 or later for `git patch-id --verbatim` and refuses older gits with `RECEIPT_GIT_TOO_OLD` naming the installed version; a product patch-id git cannot compute at either head refuses with git's own first stderr line instead of comparing an empty id; the per-path walk covers only the paths the branch itself touched and names at most `CARRY_NAMED_PATHS` (20).
+- **`gstack-review-scope defer`**: `gh repo view` receives the repository positionally (the visibility read works under `--repo`); the marker search reads one page of 200 open issues, and an exactly-full page prints `DEFERRED_SEARCH: truncated at 200 open issues` and records `filed; the marker search was truncated at 200, so an older issue may duplicate it`.
+- **Step 11 late defers** (`lib/review-scope.ts` `LATE_DEFER_SKILL`, `ship/sections/review-army.md` item 3.5): a queued adversarial finding scoped `defer` after the last Step 9 pass is logged under its own skill, `review-late-defer`; the receipt's summary counts its deferred findings, never counts it as a pass, and the dashboards that pick the newest `review` row never see it (a tokenless `review` row would read UNVERIFIED). `render` shows a filed issue's reason when it is not the plain "already filed".
+- **`ship/sections/review-army.md` Step 9.4** reordered: `0. Scope the findings` → `1. Apply the cap before any edit, then classify` → `2. Auto-fix`; scratch files live under `.gstack/tmp/` (`review-findings-p$PASS.json`, `review-classified-p$PASS.json`, `review-deferred.json`). The pass-2+ range paragraph says the outside backends receive `RANGE_BASE..HEAD`, and every specialist and Red Team prompt `scripts/resolvers/review-army.ts` renders for /ship carries its diff base as a literal sha the parent writes in (`DIFF_BASE=<diff-base>`: the merge base on pass 1, `RANGE_BASE` from pass 2 on), because a reviewer is its own process and a shell variable left in the prompt would silently re-read the whole branch.
+- **Reviewer fan-out** (`--review-fanout auto|serial|parallel`, /ship only; `docs/review-policy.md#reviewer-fan-out`): when the host reports fewer free subagent slots than selected specialists, `auto` runs them in batches of the free-slot count and prints `Fan-out: N specialists in M batches of K`; /review keeps one parallel batch because of its size pin.
+- **`ship/sections/documentation.md`** runs the shared `.gstack/tmp` exclude line and clears `.gstack/tmp/docs-audit.json` on first entry (the record is never an untracked file, whichever step reaches `.gstack/tmp` first), runs `gstack-ship-receipt docs-caps --base <base>` under "Continue or recover" before the verification gate and writes `.gstack/tmp/docs-audit.json`; `ship/sections/pr-body.md` names the verbatim exception line in the Documentation section and the receipt write adds `--docs @.gstack/tmp/docs-audit.json`. An unattended run has no owner to accept a blocked audit and stops there.
+
+- **Policy key versions** (`lib/ship-policy.ts`): `REVIEW_SCOPE_KEY_VERSION` is 1.91.256.0, the release that first read `review_scope` (its earlier value 1.91.249.0 admitted a gstack that fails on the unknown key), so a policy that set `review_scope` with `min_gstack_version` between 1.91.249.0 and 1.91.255.0 must raise it to 1.91.256.0; `DOCS_CAPS_KEY_VERSION` names the release that stamps this entry, and `test/gstack-ship-policy.test.ts` holds every unreleased key newer than the CHANGELOG headings the checkout can see.
+- **`gstack-ship-receipt write`** records `version: "none"` only when the repository has no version source at all; a `VERSION` that exists but holds no parsable version, a pin that escapes the repository or an unreadable base policy keeps the no-version refusal. `checkReceiptProse` matches a shared leaf key (`pass` under every gate lane) against any of its counters and never inside a longer word (`3 pass-through`).
+
+### Tests
+- `test/gstack-ship-receipt-docs.test.ts` (new): the docs record, exception line and doc caps, `version: "none"` for a version-less repo, the git floor, the named patch-id refusal and the branch-touched walk. `test/review-scope-followups.test.ts` (new): late-defer counting, the 200-issue truncation record, `gh repo view` positional, the two checklist rule ids. `test/ship-workflow-clarity.test.ts`: Step 9.4 order, scratch-file names, the late-defer row, `DIFF_BASE` with `RANGE_BASE` in /ship prompts only. `test/ship-frozen-scope-actor.test.ts` (new): a scripted actor passes the frozen-scope verdict with the real binaries, and the undeclared interactions, an unfixed diff defect and a one-pass exit are named failures. `test/ship-receipt-prose.test.ts` and `test/gstack-coauthor-trailers.test.ts` (new).
+- Registries: `ship-frozen-scope-convergence` in `E2E_TOUCHFILES`, `E2E_TIERS` (gate), `E2E_KINDS` (behavior) with its `BEHAVIOR_WHY`, the SDK host list, and `lib/ship-receipt-docs.ts` in the exercised-map reviewed superset and the module-size ratchet; `test/ship-skip-selection.test.ts` now expects both native ship fixtures from `test/helpers/scratch-repo.ts`.
+
+### Gate integrity
+- PR 2: the ship parity `maxSizeRatio` in `test/helpers/carve-guards.ts` moves 1.7150 → 1.7400 (measured 326,437 / 187,706 = 1.7391) for the Step 9.4 scope and late-defer prose, the docs-caps step and the version-less branch; the skeleton cap is unchanged. New case kind: `ship-frozen-scope-convergence` is `behavior` (3 trials, pass at 2) because the live model's wording of the fix and the review rows varies while the scope contract is asserted; no existing threshold, timeout, trial count or kind changed.
+
 ## [1.91.269.0] - 2026-10-27
 
 **An autoplan gate now arrives with its price, and the approvals record lands where the whole crew can read it.** Captains reported the same two frictions: review rounds and reviewer subagents had no credit figure at the gate, and the approvals mirror sat in a private project-user folder no sibling thread could read. The Eng phase also gains the performance-budget question, after a correctness pass doubled a consumer's p95 with no bench step to catch it. (The standing "take the recommendations" answer planned beside these, `answer --owner-standing rec`, was cut from this release after review: a keyword grammar over the owner's words could still read a refusal as a grant, so it returns with a structured grant in its own change.)

+## Reviewer fan-out
+
+The review army launches every selected specialist in one message so they run
+in parallel; a host that caps running subagents makes that impossible past the
+cap. In `/ship` the knob is a prompt flag, `--review-fanout auto|serial|parallel`
+(default `auto`), read where the force flags (`--all-specialists`) are (`/review`
+on its own keeps the single parallel batch: its generated SKILL.md sits at its
+size pin, and a refused launch there is a failed reader, never dropped coverage):
+
+| Value | Batches |
+|---|---|
+| `auto` | when the host reports fewer free subagent slots than selected specialists, batches of the free-slot count (at least one), each launched in one message, the next only after every reader of the previous one finished or is confirmed stopped; a host that reports no slot count runs one parallel batch |
+| `serial` | batches of one |
+| `parallel` | one batch regardless of slots; a refused launch is a failed reader, never silently dropped coverage |
+
+Capy caps a thread at 8 running subagents, and waiting or idle ones hold a
+slot, so under `auto` a nine-specialist review on an otherwise idle Capy
+thread runs as one batch of 8 and one of 1 (`Fan-out: 9 specialists in 2
+batches of 8`). Batching changes the order, never the set: every selected
+specialist runs before the merge stage, and the Red Team's activation reads
+the merged result as before.

+## Two checklist rules with ids
+
+Two findings `review/checklist.md` names by rule id so a PR body, a review log
+and a later reader agree on what was flagged:
+
+- `prereg-with-results` (Pass 1, Gate Integrity, ASK): one diff adds or changes
+  an eval's preregistration (bars, arms, decoys, stop rules, a plan file) and
+  also adds that eval's results, scores or verdict. The bar could have been set
+  after the outcome, so the pairing is the finding. The repair is a split: the
+  preregistration lands first and the results PR cites its merged commit.
+- `test-keyboard-count-loop` (Pass 2, informational): a browser-driver test
+  reaches an element by a counted loop of key presses and asserts on whatever
+  has focus, so the count encodes today's DOM order. Locate the target by role,
+  label or test id; a counted loop stays only when the count is the behavior
+  under test.

+## Porting a contributor's work
+
+A ported branch keeps the contributor's commits as theirs and adds the
+porter's fixes on top, each crediting the original authors.
+`gstack-coauthor-trailers [<range> | --base <ref>] [--message <file>]
+[--exclude <email>]...` lists every distinct author of the range's commits
+(default `origin/<base>..HEAD`) other than the checkout's own committer
+identity, in first-appearance order, as `Co-authored-by: Name <email>` lines;
+`--message <file>` adds the ones the commit message file lacks to its trailer
+block (`git interpret-trailers`, pinned placement, so an existing co-author
+keeps attribution), matched by
+email case-folded, so running it twice changes nothing. The `COAUTHORS: <n> in

+## The ship receipt
+
+The ```` ```gstack-ship-receipt ```` block is the handoff record: identifiers
+first (`pr`, `head`, `version`, `base`), then the evidence (`gate`, `ci`,
+`pregate`, `issues`, `approval`, `docs`, `review_loop`, `carry`), validated
+against the `ship-receipt` schema (`gstack-artifact schema ship-receipt`) and
+read back by `gstack-ship-receipt read`, `result`, `carry` and the queue.
+
+**`version`.** The version source at HEAD: the path `.gstack/version-path`
+pins, else `VERSION`, else `package.json#version`. A repository with none of
+those, none of the policy's `stamp_files` and no CHANGELOG (the policy's
+`changelog`, or `CHANGELOG.md`) at HEAD has no release version to record, and
+the receipt says so with `"version": "none"`: `/ship` Step 12 printed
+`Version bump: skipped (no version source: <what was looked for>)` and Step 13
+`CHANGELOG: skipped (none at <path>)`, the PR title carries no version prefix,
+and `read`, `result`, `gstack-ship-queue ready`, `train build` and `verify
+--train` accept the receipt like any other. A repository that has a CHANGELOG
+but no version source records no `version` at all (the audit still says what
+it looked for); pass `--version` to name one.
+
+**`docs`.** Step 14.5's outcome, from `gstack-ship-receipt write --docs
+<json|@file>`: `{ status: updated | current | blocked, scope, exception? }`,
+where `scope` names the docs roots the audit covered and `exception` is
+`{ accepted_by, date, via, reason }`, the owner's acceptance of a risk the
+audit could not clear. A `blocked` status with no exception is
+[`DOCS_AUDIT_BLOCKED`](troubleshooting.md#docs-audit-blocked) and nothing is
+written: only the owner accepts a documentation risk, so an unattended run
+stops there. With `--body`, the body's `## Documentation` section must carry
+the exception word for word (`Documentation exception: accepted by <owner>
+<date> via <ref>: <reason>`), or the write refuses with the same code. Doc
+caps: a repository declares `docs.caps: [{ path, max_bytes }]` in its policy,
+and Step 14.5 runs `gstack-ship-receipt docs-caps --base <base>` before the
+verification gate, reading the caps from `origin/<base>`'s policy so the branch
+cannot raise its own (`--policy <file>` only while bootstrapping a policy; an
+unreadable base policy is `POLICY_SOURCE_UNAVAILABLE`); one
+`DOCS_CAP: <path> <bytes>/<max> ok|over` line per cap
+(`absent/<max> over` for a path the tree lacks), exit 1 on any `over`, whose
+repair is trimming the file, never raising the cap in the same PR.
+
+**Prose against the receipt.** `gstack-ship-receipt read --pr <n> --check-prose`
+(or `--body <file>`) compares every counter the body quotes with the receipt's
+integers under `review_loop`, `gate` and `ci`: `passes=2`, `passes: 2` and
+`2 passes` are claims about `review_loop.passes`, `1 deferred` about
+`review_loop.deferred`, `passed: 41` about `gate.passed` (a leaf key shared by
+several counters, `passed` under `gate` and `ci` or `pass` under every gate
+lane, matches when the number equals any of them; an underscore in a key
+matches `_`, a space or `-`; a name inside a longer word, `3 pass-through`, is
+not a claim). A body that quotes a different number is
+`RECEIPT_PROSE_MISMATCH` (exit 1) and the `PROSE:` line names each field with
+both values; prose that quotes no counter is not a claim. Data PRs (evals,
+measurements, sweeps) run it before READY so the body's numbers are the run's.

+unpushed head is `QUEUE_RECEIPT_STALE` to the queue.
+
+### The review loop's counters
+
+The receipt's `review_loop` object, written from `gstack-review-scope summary
+--since <REVIEW_SINCE>`, is the loop's machine-readable outcome: `passes`
+(Step 9 passes this ship ran, 1 to 3), `blocking_found` (distinct blocking
+findings across them), `deferred` (blocking findings in unchanged code filed
+as issues, Step 11's late defers included), `noted`, `fixed` and `scope`. The
+summary line a parent reads prints it as `passes=<n> blocking_found=<k>
+deferred=<m>`; the PR body lists the deferred issues under `## Deferred
+findings` and the below-floor items under `## Review notes`. A pass that finds
+nothing is `NO FINDINGS` from every reviewer and a pass with no edits, which
+is the loop's exit, never a failed review ([review-policy.md](review-policy.md)).
+
+### The outside voice on Capy
+
+Step 11's outside adversarial review prefers the Codex CLI. On a Capy machine
+the Codex CLI is normally absent (selecting a model in Capy installs and
+authenticates no CLI), and the accepted outside voice is then a subagent
+running a different model family from the parent: a full outside voice, not
+degraded coverage, as long as the model that reviewed is recorded. Its
+review-log row is the same row every Step 11 pass writes
+(`ship/sections/adversarial.md`): `skill: "adversarial-review"`,
+`phase: "adversarial"`, `source` naming the runner that actually reviewed
+(the outside provider that reviewed, with the model recorded, for the
+cross-family subagent; `codex` for completed Codex CLI output, as
+`ship/sections/adversarial.md` prescribes),
+`outside_provider` (the provider the host would have used, as the generated
+prose names it), `outside_status` (`completed` for a finished outside pass;
+`unavailable` when neither the CLI nor a subagent completed, the cause on the
+`gstack-outside-voice run:` stderr line and in `<out>.meta.json` rather than
+in the row; `disabled` under
+`codex_reviews: disabled`), `status`
+(`clean`, `issues_found` or `unavailable`), `completed`, `converged`, and the
+subagent's model recorded with the pass (`gstack-outside-voice run --runner
+host-subagent --result <file> --model <id> --prompt <file> --out <file>` binds
+it; the row's text names it where the host reports it). The native in-host adversarial
+subagent writes its own row with `source: "in-host"`; native completion never
+credits outside coverage. A parent reads the rows with
+`gstack-review-read` and treats `outside_status: unavailable` as missing
+coverage, not as a clean outside review.
+
+### The carry across a base merge or a test-only fix
+
+When the parent merges the base in or fixes a test after the receipt was
+written, it runs `gstack-ship-receipt carry --pr <n> --base <base>` instead of
+another /ship. `CARRY: carried from <old> to <new> (<reason>)` plus the
+`GSTACK_RESULT: skill=ship status=complete run=<dir>` line means the receipt
+now names HEAD with a `carry` object holding the `git range-diff` evidence, and
+`ship-run.json` gains `carried_from` and `carry_reason`; the `review_loop`
+counters are kept, because the reviewed product diff is unchanged. `CARRY:
+current` means nothing moved. `CARRY: refused (RECEIPT_CARRY_PRODUCT_CHANGED)`
+or `(RECEIPT_CARRY_REFUSED)` with the refused result line means the product
+diff changed or the reviewed head left HEAD's history, so /ship runs again;
+`(RECEIPT_GIT_TOO_OLD)` means the machine's git predates 2.39 and cannot run
+`patch-id --verbatim` ([ship-policy.md](ship-policy.md#receipt-carry)).

A bar written in the same diff as its outcome could have been set after the outcome; the finding is the pairing, not either half. Fix: split them (the preregistration lands first; the results PR cites its merged commit), or show the preregistration's earlier merged commit in the diff.

Bash may also run each of the following as its own Bash call, with nothing joined before or after it by ;, &&, || or a pipe (a --help is no exception, so never add one to a line of reads): the exact generated Preamble block with its spawned prefix, literal installed gstack-skill-start/gstack-skill-end commands for document-release (start requires GSTACK_SESSION_KIND=spawned) or their own --help, or the literal installed ${skills}/bin/gstack-docs-candidate snapshot (its --out a private .json under ${fixture.home}), compare <that .json> and --help commands. ${readOnlyInterfaceText(fixture.home)} The Git reads above may join such a line too, but not in a line with cd. A for loop over literal words (a lowercase loop variable; words without quotes, globs or $) whose body uses only such reads counts as those reads, one pass per word, wherever it sits in the line. Every read stays off actor-state.json and off ${docsConfigDir(fixture.home)} except its settings.json: that directory holds Claude's credentials and every agent's session transcript, so judge a child only by the output it returns (its echoed SESSION_KIND line included) and by the repository. The additional scripts below also run each as its own Bash call; no own-call command ever joins such a line. Otherwise no shell composition, custom interpreters, arbitrary scripts, inline eval or memory-mapped writes. The only additional scripts are ${scripts.length ? scripts.join(', ') : 'none'}.${insert ? ` To insert one saved private Markdown artifact into another (a saved section file into a report), Bash may also run the single literal command cat SOURCE.md >> TARGET.md with absolute paths under ${fixture.home}.` : ''} Read/Glob/Grep remain available; Read skill and section files with Read (offset/limit for ranges), because Bash output over 30KB becomes a truncated preview. A private JSON/Markdown artifact (the snapshot --out file, saved child output, a section or report file) lives directly under ${fixture.home} or in a new directory you create there, never inside the repository, ${skills}, ${docsConfigDir(fixture.home)}, ${state} (gstack's own state directory, not a place for your files) or ${fixture.home}/remote.git. Use Write/Edit for permitted docs and those private artifacts; do not rewrite installed skills, config, actor state or scripts. No effects outside the owned fixture.

+  return `Fixture observation interface (applies to parent and every child; ${file ? `saved at ${file}: each child prompt tells the child to Read that file first instead of copying this text` : 'include this interface in child prompts'}): Bash may execute only separate literal pwd, ls, cat, stat, sha256sum and Git read commands (status, diff, show, log, ls-files, ls-tree, check-ignore, rev-parse, merge-base, hash-object without -w, branch --show-current, describe with only --tags, --always, --abbrev=<n> or --exact-match and at most one revision). Bash may also run each of the following as its own Bash call, with nothing joined before or after it by ;, &&, || or a pipe (a --help is no exception, so never add one to a line of reads): the exact generated Preamble block with its spawned prefix, literal installed gstack-skill-start/gstack-skill-end commands for document-release (start requires GSTACK_SESSION_KIND=spawned) or their own --help, or the literal installed ${skills}/bin/gstack-docs-candidate snapshot (its --out a private .json under ${fixture.home}), compare <that .json> and --help commands, and /ship Step 14.5's three own-tree housekeeping commands exactly as written, each on its own line: the shared .gstack/tmp exclude line (the one &&-joined housekeeping line this interface admits)
+${DOCS_TMP_EXCLUDE}
+then
+${DOCS_AUDIT_RESET}
+and the cap gate, which reads origin/main's policy and whose DOCS_CAP lines and exit status decide it
+${docsCapsCommand(skills)}
+(no --json, no other base, no other gstack-ship-receipt subcommand). ${readOnlyInterfaceText(fixture.home)} The Git reads above may join such a line too, but not in a line with cd. A for loop over literal words (a lowercase loop variable; words without quotes, globs or $) whose body uses only such reads counts as those reads, one pass per word, wherever it sits in the line. Every read stays off actor-state.json and off ${docsConfigDir(fixture.home)} except its settings.json: that directory holds Claude's credentials and every agent's session transcript, so judge a child only by the output it returns (its echoed SESSION_KIND line included) and by the repository. The additional scripts below also run each as its own Bash call; no own-call command ever joins such a line. Otherwise no shell composition, custom interpreters, arbitrary scripts, inline eval or memory-mapped writes. The only additional scripts are ${scripts.length ? scripts.join(', ') : 'none'}.${insert ? ` To insert one saved private Markdown artifact into another (a saved section file into a report), Bash may also run the single literal command cat SOURCE.md >> TARGET.md with absolute paths under ${fixture.home}.` : ''} Read/Glob/Grep remain available; Read skill and section files with Read (offset/limit for ranges), because Bash output over 30KB becomes a truncated preview. A private JSON/Markdown artifact (the snapshot --out file, saved child output, a section or report file) lives directly under ${fixture.home} or in a new directory you create there, never inside the repository, ${skills}, ${docsConfigDir(fixture.home)}, ${state} (gstack's own state directory, not a place for your files) or ${fixture.home}/remote.git. Use Write/Edit for permitted docs, those private artifacts and Step 14.5's receipt record ${fixture.repo}/${DOCS_AUDIT_RECORD} (the only permitted write under the repository besides the document, excluded from git by the line above); do not rewrite installed skills, config, actor state or scripts. No effects outside the owned fixture. The owner preserves evidence and cleans up. Missing observer coverage blocks acceptance; the Linux kernel monitor covers syscall writes in the product tree, not hostile processes or arbitrary external destinations.
 
 The working directory for parent and child Bash calls is already ${fixture.repo}. Run Git reads directly, for example: git status, git diff --cached, git merge-base main HEAD, git rev-parse HEAD. Do not use Git global options such as -C, -c, --git-dir or --work-tree, and do not prepend cd or another shell wrapper. The literal git subcommand must immediately follow git; an absolute owned repository path does not make git -C an allowed command.

This invocation runs unattended (SESSION_KIND: headless, no owner present) under review_scope policy \`frozen\` with base \`origin/main\`, on branch fixture/frozen-scope in ${repo}. PASS is 1 and CYCLES is 0 on entry. The pass-1 Step 9.3 result is already written at ${findingsPath}; verify each finding against its source (${invoice}, ${payments}) before acting on the classified output. Execute the workflow through its decision, pass by pass, until the decision continues to Step 10 or stops the loop.
+
+Supported interactions, declared before launch:
+- Read: ${workflowPath}, ${invoice}, ${payments}, and any file under ${tmp}/ once it exists.
+- Edit or Write: ${invoice} only, and only to apply a fix for a finding the classified output scopes \`fix\`. ${payments} is never written in this fixture. Write also accepts ${draft}, the item-6 review record of the current pass: the JSON object the gstack-review-log example takes (skill, timestamp, status, issues_found, critical, informational, quality_score 10.0, specialists {}, findings with fingerprint, severity, action and the copied locus, kind and blocking, commit, via "ship", completed, converged, cycles, pass, review_scope, range_base). The record's commit is the short HEAD: ${head.slice(0, 7)} now, and the sha the commit adapter prints after it commits a fix; no git command is needed for it.
+- Bash accepts exactly these single commands, without chaining, redirection or backgrounding. Each is the bound adapter for the generated helper command it names and does not decide which item or decision applies:
+  ${commands.classify} runs gstack-review-scope classify for the current pass against this pass's .gstack/tmp/review-findings-p$PASS.json (--range-base is bound from pass 2 on); it writes .gstack/tmp/review-classified-p$PASS.json and prints the REVIEW_SCOPE line and the classified JSON.
+  ${commands.defer} runs gstack-review-scope defer on the current pass's classified file; it writes .gstack/tmp/review-deferred.json and prints the DEFERRED lines and the rendered PR-body sections (gh is absent here, so a deferred finding stays unfiled with its reason).
+  ${commands.persist} passes ${draft} to the real gstack-review-log with this pass's REVIEW_START token (--finish); the pass-1 token was captured before this prompt, and the repeat adapter captures the next one.
+  ${commands.commit} runs item 4's commit of the fixed file (git add invoice.ts && git commit -m "fix: pre-landing review fixes").
