Merge origin/main (f27a7605, v1.91.270.0) into absorb-b-pr-body-blast-radius-prose-lint (rule 19 grant 3, GSTA-36)

CHANGELOG via mergeChangelogs; NOTICE.md additive (main's pstack blocks first, this PR's unslop entry after); docs/capy-install.md takes #3496's sentence with "Blast radius" added; result codes, troubleshooting anchors and the doctor-components render additive (regenerated); ship parity cap re-measured on the merged tree: 328,319 / 187,706 = 1.7491, pinned at 1.7500.

+
+### 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.)
+
+### Added
+- **`GATE_SPEND:` and `GATE_REC_COST:`** (`lib/autoplan-gate-cost.ts`; printed by every gate-producing `gstack-autoplan` command under `GATE:`, by `run` when it stops at a gate, and as `gate_cost` in the `--json` payloads): the run's ledger at the gate (spent, worst case, cap, headroom, attempts; host-subagent attempts are priced `unknown` and counted at their reservation, with a pointer to the host's own cost view instead of an invented figure) and the price of `rec` as an upper bound from the answer and revise rules (a plan change counts every phase `revise` can keep or add, since it reopens each phase whose snapshot the edit changes and re-detects scope, so a run that skipped Design or DX without `--no-ui`/`--no-dx` counts them too; a round grant counts its phase and Eng; the effective choice per item is parseReply's (an answer already recorded at this gate revision, else the carried choice, else the recommendation), a recorded plan rerun `p1d` prices every phase, a reject or stop nothing, and an override of the recommendation counts as `answer` counts it; two voices each with the outside voice on, at the per-voice reservation the run has been making; a reopen past the cap says so). `gstack-owner-brief render` carries the same figures as one `Cost so far:` sentence under its Summary, and `render --captain` carries them as a `### Cost` section above the relaying-agent trailer, so the person approving sees it.
+- **The Captain-named approvals directory** (`lib/approval-record.ts` `captainApprovalsDir`): on Capy the mirror is `GSTACK_APPROVALS_DIR` when set, else the `approvals/` directory in the one mounted Captain drive (`~/.capy/drive/captain-*/approvals/<slug>/<branch key>.jsonl`, readable by every crew thread), else the private project-user folder as before; two Captain drives with one each is ambiguous and falls through. The other roots are still read (`read_also`), so a row mirrored under the earlier rule stays visible to `list` and `render`; `gstack-approvals path` prints which rule chose the mirror and the `READ_ALSO:` roots.
+
+### Changed
+- **Eng phase, Section 4 (Performance)** (`autoplan/sections/eng-phase.md.tmpl`): a hot path with no performance budget or bench step is a finding, and the consensus table's row 3 asks "Perf risks + budget/bench named?". Five nearby phrases were shortened by the same number of characters, so every host's generated autoplan SKILL.md stays at its size-guard pin (raising a pin is an owner decision).
+- **`autoplan/DRIVER.md`, `docs/capy-install.md`, `docs/unattended.md`, `docs/recommended-harness.md`, `capy/skill/gstack/captain.md`, `docs/troubleshooting.md`**: the loop relays the two cost lines with every gate render; the Captain sections name the crew-readable mirror and the `READ_ALSO:` roots; the brief descriptions carry the `### Cost` section; the `APPROVAL_RECORD_UNAVAILABLE` fix names the three mirror sources. `capy/skill/gstack/SKILL.md` is untouched here (it is #3475's file) and points at `autoplan/DRIVER.md` already.
+
+### Tests
+- `test/autoplan-gate-cost.test.ts` (new): `recReopens` as the upper bound (plan change counts every phase revise can keep or add, a round grant its phase plus Eng, carried items only when changed, overrides, `p1d`/`p1c`/`p1e`), `priorChoices`, and the two cost lines from a ledger with an unknown host attempt (cap, no cap, over the cap, no ledger); the mirror chain (project-user, one Captain drive, two, `GSTACK_APPROVALS_DIR`, mirror off) and `gstack-approvals path` with `READ_ALSO:`; end-to-end runs through `bin/gstack-autoplan`: the closing submit prints `GATE_SPEND:`/`GATE_REC_COST:` (text) or `gate_cost` (`--json`), the owner brief carries the `Cost so far:` sentence, `render --captain` a `### Cost` section above its trailer, and `run` at a pending gate prints the gate lines once (one `--json` payload).
+
+### Gate integrity
+- No threshold, rubric, trial count, case kind or judge prompt changed. The only prompt edit is the Eng phase's performance paragraph; the one paid autoplan case (`autoplan-dual-voice`) reads Phase 1, which is untouched.
+
+## [1.91.268.0] - 2026-10-27
+
+**Two read-and-write helpers absorbed from pstack: a decision trail a reviewer reads without the transcript, and a worktree audit that tells you which Conductor worktrees are safe to remove.** Both are ports of Lauren Tan's MIT scripts (header credit in each file, `licenses/MIT-pstack.txt`, NOTICE.md), approved with the rest of the pstack absorb (Garry, 2026-10-26: "Do it, send").
+
+### Added
+- **`bin/gstack-decision-trail <file> <phase> <decision> <why> <evidence> <result>`**: appends one UTC-stamped row to a run's TSV decision trail, writing the header once and only ever appending; cells are flattened to one line and a cell that starts with `=`, `+`, `-` or `@` gets a leading quote so evidence lifted from a PR title or a filename cannot run as a formula in a reviewer's spreadsheet. `start <file> <run-id>` appends a run's `start` row (naming the earlier rows and `run:<id>`; the id is letters, digits and `. _ : @ / -`, so a tab or quote in it is a usage error rather than a row that breaks the idempotence check) and is a no-op while that row is the newest start row, so a rerun writes nothing twice; only a leading `-h`/`--help` is help, so a cell whose text is `-h` is appended as data; a trail without a final newline, with CRLF rows, a UTF-8 BOM, a repeated header line or no header at all is appended to correctly; `--run <id>` on an append refuses with `DECISION_TRAIL_START_REQUIRED` (exit 3) until the run has opened its stretch. The end-of-run rule, in `docs/unattended.md` ("The decision trail") and `autoplan/DRIVER.md`: audit the trail against the transcript and correct the log, not the story (a wrong row is superseded, never edited), then a reviewer on another model family reads it and the report ends with an `Attention` section (`reviewed by <model>`, the flags, or `No flags`).
+- **`bin/gstack-worktree-audit [-b <ref>] [--no-fetch] [repo]`** (bash, read-only): one TSV row per git worktree beside the main one, largest first: size, age, merged into the base, `clean`/`wip:<n>`/`scratch:<n>`, `pushed`/`ahead<n>`/`no-remote`/`detached`, the PR on its branch through `gh`'s own `--jq` (no `jq` needed), the newest Claude Code chat that ran in the worktree (`${CLAUDE_CONFIG_DIR:-~/.claude}/projects/<slug>`) and a bucket: `prunable` (registered, directory gone), `hold-wip`, `hold-open-pr`, `verify-recent-chat`, `safe`, `review`. `safe` means nothing exists only in that worktree: a clean tree that is merged into the base or whose PR is closed or merged with every commit pushed; an unpushed commit or an untracked file on a merged branch reads `review`. A fork's PR on a same-named branch is ignored and an open PR wins over an older closed one on a reused name. A locked entry whose directory is gone and a `broken` worktree whose own `.git` link is missing (git would otherwise describe the containing repository and hide its files) read `review`; a clean tree names its gitignored entries as `clean,ignored:<n>` without changing the bucket; a branch name shared with a tag still resolves; worktree paths with leading, trailing or inner spaces are read whole. It never deletes or prunes; its one write is a best-effort fetch of the base ref that `--no-fetch` skips. `/landing-report` offers it when the sibling table shows stale worktrees; `docs/CONTRIBUTOR_REFERENCE.md` has the guide for Conductor users, `docs/standalone-binaries.md` lists both bins.
+
+### Tests
+- `test/decision-trail.test.ts`: header once (an empty file gets one, a second append does not), the formula guard on every leading byte it covers, flattened tabs and line breaks, the start row's text and its idempotent rerun, a second run's start row, the `--run` refusal and admission, a `-h` cell appended as data, a missing final newline, CRLF rows and a repeated header, a blank file and a BOM, run ids with whitespace or quotes refused, usage errors.
+- `test/worktree-audit.test.ts`: a bare origin, a clone and twelve worktrees (merged, wip with an open PR, scratch with a chat today, stale, closed PR, a merged one whose path has a space, a merged one with only an untracked file, a registered one whose directory is gone, a locked one whose directory is gone, a broken one inside the clone with a precious file, one whose branch shares its name with a tag, one with only a gitignored `.env`) classified into every bucket (also under `status.showUntrackedFiles=no`, which must not hide untracked files) through a fake `gh` (which records its arguments and runs the audit's own `--jq` over canned JSON with a fork PR when `jq` is installed) and a `CLAUDE_CONFIG_DIR` transcript directory; the fixture, its worktree registry included, is byte-identical after the audit; `-b`, `--no-fetch`, an unpushed commit on a closed PR reading `review` and an open PR on the reused name winning, no `gh` on PATH (git resolved from `git --exec-path`, so a distribution's wrapper script does not matter), a failing `gh`, a missing base and a non-repo path.
+
+### Gate integrity
+- No threshold, timeout, trial count or case kind changed. No pinned skill changed; `landing-report/SKILL.md` grows by one line and is unpinned. `test/autoplan-driver.test.ts`'s line cap on `autoplan/DRIVER.md` moves 160 → 162 (measured 162) for the decision-trail paragraph at the end of the coordinator contract section; the file was at the cap before.

+ * The start-row rule is gstack's mechanisation of the same skill's prose: a run
+ * (one agent conversation, with its later turns) that writes to a trail already
+ * holding rows opens with a `start` row naming the rows it did not write, and
+ * its evidence names the run (`run:<id>`). `start` is idempotent for the same
+ * id, and an append with `--run <id>` refuses until that run's start row is the
+ * newest start row in the file (DECISION_TRAIL_START_REQUIRED, exit 3).

+# gstack-worktree-audit — read-only audit of every git worktree beside the main
+# one: size, age of its last commit, whether its head is merged into the base,
+# tracked edits vs untracked scratch, remote state, the PR on its branch, the
+# newest Claude Code chat that ran in it, and a suggested bucket. One TSV row
+# per worktree, largest first. It never deletes, prunes, checks out or edits a
+# worktree or a branch; its one write is the best-effort fetch of the base ref
+# (skip it with --no-fetch). In a fork workflow, where origin is your fork and
+# gh resolves the upstream, every PR is cross-repository and the PR column is -. Removing a worktree stays a step a person takes
+# after reading the table.
+#
+# Ported from pstack's poteto-mode/scripts/worktree-audit.sh (Copyright Lauren
+# Tan, MIT; https://github.com/cursor/plugins, pstack/skills/poteto-mode at
+# 99b609a7). Changes from the source: the PR column comes from gh alone through
+# its own --jq (no jq binary) and ignores fork PRs, LAST_CHAT reads Claude
+# Code's per-worktree transcript directory instead of Cursor's, worktree paths
+# may contain spaces, a registered worktree whose directory is gone gets a
+# `prunable` row, `safe` also requires a clean tree with nothing unpushed, and
+# --no-fetch is new. License
+# text: licenses/MIT-pstack.txt; NOTICE.md carries the entry.
+#
+# Usage: gstack-worktree-audit [-b|--base <ref>] [--no-fetch] [repo-path]
+#   repo-path defaults to the repository the current directory is in.
+#   -b sets the ref the MERGED column checks against (origin/integration, say).
+#      Without it the base is origin/HEAD, then origin/main, then origin/master,
+#      and a warn line says which one was picked: origin/HEAD is the remote's
+#      default branch, not necessarily the branch PRs merge into.
+#   --no-fetch skips the best-effort fetch of the base before the merge check.
+#
+# Columns: SIZE AGE MERGED DIRTY REMOTE PR LAST_CHAT BUCKET WORKTREE

+`scratch:<n>` (untracked only) / `missing` (registered, directory gone) /

+`detached` (against the local `origin/<branch>` tracking ref as last fetched),
+the PR on its branch through `gh` (`#n/open|merged|closed`, or `-`; a fork's
+PR on a same-named branch is ignored, so in a fork workflow where `origin` is
+your fork the column is `-`, and an open PR wins over an older closed one on a
+reused branch name), the date of the newest Claude Code chat that ran in it,
+and a bucket: `prunable` (registered, directory gone, not locked), then
+`review` for a locked entry whose directory is gone or a `broken` worktree
+whose own `.git` link is missing, then `hold-wip`, then `hold-open-pr`, then
+`verify-recent-chat` (a chat in the last four days), then `safe`, else
+`review`. `safe` means nothing tracked or untracked exists only in that
+worktree: a clean tree whose head is merged into the base, or whose PR is
+closed or merged with every commit pushed; an unpushed commit or an untracked
+file on a merged branch is `review`. Ignored entries do not change the bucket,
+but removing the worktree removes them too, so read the `ignored:<n>` count
+before you do. A squash-merged branch is never an ancestor of the base, so read
+`MERGED` together with `PR`. The audit only reads, apart from a best-effort fetch

+## 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

+
+- `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.

+`--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

+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

+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,

The offer triggers on large repos (1,000+ tracked files; a decline is persisted). Non-local providers refuse to index *or search* until you record per-repo consent (`consent <repo> yes\|no` — the query text is repo-derived content), the per-repo trust policy's deny and read-only tiers veto write-class operations regardless of consent, and every off-machine send writes an egress receipt.

Hooks bypass the permission system, so a declared command never runs until you trust it once per repo (`gstack-verify-gate --trust`); editing the command invalidates trust until re-granted, and every grant is audit-logged. `./setup` never registers it for you — opt in with `gstack-settings-hook add-event --event Stop --command ~/.claude/skills/gstack/bin/gstack-verify-gate --source verify-gate`, remove with `gstack-settings-hook remove-source --source verify-gate`. |

+## What /ship leaves for a parent
+
+One section for everything a parent (a Captain, a crew thread, a merge queue)
+reads after an unattended `/ship`: the READY evidence, the review loop's
+counters, the outside voice's record, and the carry across a base merge.
+
+### The READY evidence: `gstack-ship-receipt result`
+
+`/ship` Step 22 runs `gstack-ship-receipt result --pr <n>` (or `--body
+.gstack/tmp/ship-receipt.md` after the handoff section). It binds the receipt
+in the PR body (or the handoff file) to HEAD, writes
+`<state root>/ship/runs/<utc>-<head12>/` and prints the terminal line:
+
+```
+GSTACK_RESULT: skill=ship status=complete run=<dir>
+```
+
+The run directory holds `ship-receipt.md` (the block, copied) and
+`ship-run.json` with `head`, `pr`, `base`, `version` (`"none"` for a
+repository with no version source, [ship-policy.md](ship-policy.md#ship-receipt)),
+`queue_mode`, `session_kind`, `receipt` (the copied block's path) and
+`receipt_source`. It is a /ship record, not the `run` v1 manifest below, so
+read it directly; `gstack-artifact validate` does not apply. A parent's merge
+check is then mechanical: take `run=` from the last result line, read
+`ship-run.json`, compare its `head` to the PR head, and quote the
+`SHIP_RECEIPT: pr=<n> head=<head12> …` line in the READY block.
+`gstack-ship-queue ready`, `train build` and `verify --train` make the same
+comparison from the PR body ([ship-policy.md](ship-policy.md#ship-before-ready)).
+
+The other endings, each greppable: when gh cannot read the PR,
+`GSTACK_RESULT: skill=ship status=incomplete run=-` (exit 1); a receipt that is
+missing or names another head, `GSTACK_RESULT: skill=ship status=refused run=-`
+with `QUEUE_RECEIPT_MISSING` or `QUEUE_RECEIPT_STALE` on stderr (exit 3), the
+line a run that stops before publication prints itself; and `result --pr <n>`
+refuses `QUEUE_RECEIPT_STALE` when HEAD is not the PR's pushed head.
+
+The one publication the unattended rules allow: when an open PR for the branch
+exists and HEAD is its pushed head, Step 18 takes the pr-body section's
+existing-PR path and posts the body (receipt first) and title through
+`gstack-post`. It never runs `pr-create`, never pushes a commit and never runs
+`gh pr ready`; a branch with no open PR, or whose PR head is not HEAD, takes
+the handoff section. When the run committed anything (a CHANGELOG entry,
+generated tests), the parent pushes those commits itself, then reruns the
+receipt write, the body post and `result` at the pushed head: a receipt for an
+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

+## The decision trail
+
+A long or unattended run keeps one tab-separated trail of its decisions at
+`<run dir>/decisions.tsv`, written through `gstack-decision-trail <file>
+<phase> <decision> <why> <evidence> <result>`, so the parent reads what the run
+chose and why without the transcript. The helper stamps the time, writes the
+header once, flattens each cell to one line and quotes a cell that starts
+with `=`, `+`, `-` or `@`, so evidence lifted from a PR title or a filename
+cannot run as a formula when a reviewer opens the file in a spreadsheet.
+Log the forks, not the keystrokes: an approach chosen or dropped, a unit done
+with its verification result, a revert and what triggered it, a blocker, one
+row per iteration of a loop. Evidence is a pointer that resolves (a commit, a
+PR, `file:line`, an artifact path), never prose. A run that joins a trail
+other runs wrote (a pickup after a crash, a replacement machine, a later turn
+of the same thread) first runs `gstack-decision-trail start <file> <run id>`,
+which appends a `start` row naming the earlier rows and the run; appends with
+`--run <id>` refuse (`DECISION_TRAIL_START_REQUIRED`) until that row is the
+newest start row, and `start` is a no-op when it already is, so a rerun of the
+same step writes nothing twice.
+
+Before it hands back, the run audits the trail against what it did: every row
+of its own stretch (from its `start` row to the next run's) maps to a real
+decision or action, every evidence pointer resolves and shows what the row
+claims, and a fork or abandoned approach that shaped the result but is not
+logged gets a row. The audit corrects the log, never the story: no row is
+edited or removed, an invented or wrong row stays and a new row supersedes it
+with what actually happened. Then a reviewer on a different model family from
+the one that did the work (a Capy subagent on another family, or the outside
+voice) reads the trail and the transcript and flags what the owner should look
+at: decisions with weak or missing evidence, verification claimed without
+proof, choices that look risky in hindsight, gaps a skim would miss. The run's
+final report ends with an `Attention` section that opens with `reviewed by
+<model>` on its own line and lists each flag against its rows; `No flags` is a
+valid body, a missing model line is not. Self-review does not stand in for
+this. `decisions.jsonl` stays the typed record `gstack-artifact` validates; the
+trail is the plain one a person reads, and `column -s$'\t' -t decisions.tsv`
+renders it in a terminal.

Resolve it read-only (`~/.claude/skills/gstack/bin/gstack-decision-search --query "<dec-id>"`; the named `ship-measure` report if it exists) and pre-fill the Keep — justified option with the citation marked **verified** or **unverified**; the finding still reaches the ASK.

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.

Each declared `APPROVAL_CLASS:` line (an upgrade-time row rewrite, a trust or visibility change, an existing-user default flip, a data repair, as the repo declares them) is a finding that needs the owner's approval: name its `APPROVAL_SCOPE: <class>@<digest12>` token, because /ship's receipt refuses (`APPROVAL_CITATION_MISSING`) until the PR body cites an approval bound to it.

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").
+  ${commands.repeat} takes decision 3: it runs the next pass's Steps 5 through 9.3 on the range since the previous pass, writes that pass's .gstack/tmp/review-findings-p$PASS.json and prints the result with the new REVIEW_START captured.
+  ${commands.continue} takes decision 4 (no edits in this pass): continue to Step 10 and stop this fixture.
+  ${commands.stop} takes decision 1 or 2: STOP the loop and stop this fixture.
+No owner can answer here, so AskUserQuestion is not available: a finding the classified output scopes \`fix\` is resolved as AUTO-FIX under the Fix-First heuristic, and no finding is skipped. The gate scan of item 2.5, freshness, memory updates and Step 10 itself are outside this fixture. Stop after the continue or stop adapter completes.`;
