Merge origin/main (v1.91.7.0) into test-audit-reduction

Keep both intents: v1.91.7.0's functional QA, docsync and exploratory
paid cases and their free owners stay; this branch's deletions stay
deleted. main's new paid keys follow the derived-closure touchfile rule
(free *.test.ts paths dropped, static helper/fixture closure added), its
new helper-only tests join the ratchet baseline, and its free selection
examples that named free test files now assert the derived selection.

Periodic CI keeps seven slices without the retired Autoplan slice; the
gate census keeps seven single-worker slices with --skip-judges. Wall
and census literals are recomputed from the merged planner, durations
are re-recorded on Ubicloud, and VERSION stays 1.91.8.0 above 1.91.7.0.

 # Ship: Fully Automated Ship Workflow
 
-Run `/ship` through to the PR URL. This request authorizes routine work without confirmation; explicit safety and user-decision gates still apply.
+STOP blocks advancement until the stated repair/resume route clears; without one, end this attempt.
+Answer each AskUserQuestion before continuing.
+Routine authorization never waives those gates or their required user decisions.
 
-**Route through the workflow:** detect and merge the base (Steps 1–3), test and
-audit the integrated diff (Steps 4–8.2), review and resolve findings (Steps
-9–11), prepare the release and commits (Steps 12–15), then verify, push, sync
-docs, and open or update the PR (Steps 16–19). A review fix returns to affected
-tests and reviews before release preparation; a later code or build-input edit
-returns to affected checks and Step 16 before publication. Reuse still-valid
-results, but never treat an earlier review or test as covering changed inputs.
+**Routine work needs no confirmation:** include uncommitted changes, choose MICRO/PATCH
+under Step 12, draft CHANGELOG and commits, mark completed TODOs and auto-fix findings.
+When Step 7 coverage meets its target, report remaining gaps and verify generated
+tests without another permission question. Step 15 commits those tests.
 
-**Follow every STOP and AskUserQuestion gate**, including:
-- On the base branch (abort)
-- Merge conflicts that can't be auto-resolved (stop, show conflicts)
-- In-branch test failures (pre-existing failures are triaged, not auto-blocking)
-- Pre-landing review finds ASK items that need user judgment
-- Prior Learnings needs its first-time cross-project setting (Step 8)
-- MINOR or MAJOR version bump needed (ask — see Step 12)
-- Greptile review comments that need user decision (complex fixes, false positives)
-- AI-assessed coverage below target (see Step 7 for minimum/target decisions)
-- Plan items NOT DONE or UNVERIFIABLE (see Step 8)
-- Plan verification failures (see Step 8.1)
-- TODOS.md missing and user wants to create one (ask — see Step 14)
-- TODOS.md disorganized and user wants to reorganize (ask — see Step 14)
+**Route:** integrate (1–3) → test and review (4–11.5) → prepare the release
+(12–15) → verify frozen content (16) → push and publish (17–21).
+Every new invocation repeats Steps 1–16, including both reviews and the docs audit.
+Steps 12, 17 and 19 prevent duplicate bumps, pushes and PRs, never verification.
 
-**Never stop for:**
-- Uncommitted changes (always include them)
-- Version bump choice (auto-pick MICRO or PATCH — see Step 12)
-- CHANGELOG content (auto-generate from diff)
-- Commit message approval (auto-commit)
-- Multi-file changesets (auto-split into bisectable commits)
-- TODOS.md completed-item detection (auto-mark)
-- Auto-fixable review findings (dead code, N+1, stale comments — fixed automatically)
-- Test coverage gaps within target threshold (generate, verify, then commit with Step 15; flag any remaining gaps in the PR body)
+### Keep state between steps
 
-**Re-run behavior (idempotency):**
-Every invocation repeats verification: tests, coverage, plan completion, both
-reviews, VERSION/CHANGELOG, TODOS and doc-sync. Only *actions* are idempotent:
-- Step 12: If VERSION already bumped, skip the bump but still read the version
-- Step 17: If already pushed, skip the push command
-- Step 19: If PR exists, update the body instead of creating a new PR
-Prior execution never exempts verification.
+Keep one private Markdown **invocation record** outside the product tree and save
+its absolute path. Use these headings so a paused run can resume:
+- **Release:** versions, `BUMP_LEVEL`, reviewed tree and attempt counts.
+- **Decisions:** each approval's finding, files and authorized action. Reuse it only
+  for that same scope; a repair never resets approvals or expands them.
+- **Reviews:** handles, original start tokens, terminal states, outputs and queued fixes.
+- **Checks:** command/label, result/counts, timestamp, log and consumed inputs.
+- **Documentation:** candidate/id, attempts used, accepted hashes or named blocked exception.
+- **Next steps:** one ordered work list, with the current step marked.
+
+A **receipt** is saved evidence of a check's command, result and consumed content.
+A review's **start token** is the opaque value returned by `gstack-review-log --start`
+before it reads the diff. Keep `REVIEW_START` for Step 9, a separate `PASS_START` for
+each Step 11 attempt, and `DESIGN_START` for design. Finish each pass with its original
+token; `--finish` stamps the binding fields automatically. Never borrow or replace a token.
+`gstack-wtree` prints a Git tree hash covering tracked and non-ignored untracked files,
+not a commit ID. Use `git diff <old-tree> <new-tree>` to compare these snapshots.
+
+### Ship control flow
+
+You, the **parent** running /ship, own advancement; children return evidence, not
+permission to proceed. Follow the saved work list:
+
+1. Start with Steps 1–21 in order, including 11.5 and 14.5. Advance only after
+   the current item's gates clear.
+2. Expand a repair into individual steps and insert them before the still-pending
+   work. This replaces the current item, whose actual result stays in the record.
+   Add its destination only if not already the next pending step.
+3. For another repair, repeat rule 2 without discarding pending work.
+   The saved list takes precedence over ordinary next-step
+   sentences inside a repair. A range never adds unlisted steps.
+
+**Example:** Step 11 fixes insert `9 → 10 → 11` before 11.5. A further Step 9 fix
+affecting 6–8 makes the list `5 → 6 → 7 → 8 → 9 → 10 → 11 → 11.5`.
+The unchanged release steps follow. STOP and AskUserQuestion gates still apply during repairs.
+
+Keep the same attempt counts throughout the invocation. A range ending at Step 14
+does not enter Step 14.5. A range that includes Step 14.5 enters its existing audit
+decision, not an unconditional new launch; its initial-plus-ONE limit never resets.
+Permitted repairs continue in this invocation without restarting /ship.

+- **Content-first rule:** For `review`, `adversarial-review`, `codex-review`,
+  ship-stage reviews and `design-review-lite`, use `review_freshness.status`
+  and show its `reason`. CURRENT means a completed clean review whose start and
+  end content fingerprints equal the current `---WTREE---` fingerprint. This
+  fingerprint covers working-tree content, not just the commit.
+  STALE or UNVERIFIED cannot clear Eng Review. Missing `review_freshness`,
+  including legacy log-only records, means UNVERIFIED. Never fall back to HEAD
+  equality or commit distance for diff evidence, even at zero commits.
+  Show recorded cycles, completed/converged fields and missing source/phase
+  coverage. Unknown coverage is not a pass.
+- **Plan records** (plan-ceo-review, plan-eng-review, plan-design-review and
+  codex-plan-review) use the 7-day window, not the working-tree fingerprint.
+  If `plan_sha256` is present, you may compare the plan file and report a mismatch.
+  For plan records only, compare the recorded commit with `---HEAD---`.
+  If different, run `git rev-list --count STORED_COMMIT..HEAD` and report
+  "Note: {skill} review from {date} may be stale — {N} commits since review".
+  A failed command means UNKNOWN, treated as stale. Without commit tracking,
+  retain the note to consider re-running. Omit staleness notes when all reviews
+  are current.
 
-**Review tiers:**
-- **Eng Review (historical readiness):** Required for a CLEARED dashboard, not for continuing Step 1. Step 9 remains mandatory, with its finding, approval and convergence gates. The skip_eng_review setting changes this dashboard only.
-- **CEO Review (optional):** Use your judgment. Recommend it for big product/business changes, new user-facing features, or scope decisions. Skip for bug fixes, refactors, infra, and cleanup.
-- **Design Review (optional):** Use your judgment. Recommend it for UI/UX changes. Skip for backend-only, infra, or prompt-only changes.
-- **Adversarial Review (automatic):** Always-on for every review. Every diff gets a native adversarial pass and, when enabled and available, a host-selected outside challenge. Large diffs (200+ lines) additionally get a structured outside review with P1 gate.
-- **Outside Voice (default-on):** Independent plan review through the host-selected provider after /plan-ceo-review and /plan-eng-review. The codex_reviews switch disables the entire extra step. Provider failure uses the existing native fallback and reports missing outside coverage. Never gates shipping.
+**3. Choose the historical verdict.** CLEARED requires the selected Eng Review
+to be `clean`, within 7 days and fresh under step 2. Otherwise report NOT CLEARED
+and its missing, stale or open-issue reason. If `skip_eng_review` is true, show
+"SKIPPED (global)" for Eng Review and CLEARED for this dashboard.
+This verdict never skips Step 9 or its finding, approval and convergence gates. Continue Step 1 even when history is NOT CLEARED.
 
-**Verdict logic:**
-- **CLEARED**: Eng Review has >= 1 entry within 7 days from either \`review\` or \`plan-eng-review\` with status "clean"; diff review must also grade CURRENT below (or \`skip_eng_review\` is \`true\`)
-- **NOT CLEARED**: Eng Review missing, stale (>7 days), or has open issues
-- CEO, Design, and outside reviews are shown for context but never block shipping
-- If \`skip_eng_review\` config is \`true\`, Eng Review shows "SKIPPED (global)" and verdict is CLEARED
+Other rows provide context, not a substitute for Eng Review:
+- Recommend CEO Review for product/business or scope decisions, not routine fixes or cleanup.
+- Recommend Design Review for UI/UX work, not backend, infrastructure or prompt-only work.
+- Adversarial review always includes a native pass. Available, enabled outside
+  challenges supplement it; diffs of 200+ lines also get the structured P1 gate.
+- Outside Voice is the default-on plan review after CEO/Eng review. `codex_reviews`
+  disables that extra step. Provider failure uses native fallback and records
+  missing outside coverage; this dashboard row never gates shipping.
 
-**Staleness detection:** Grade before deciding CLEARED:
-- Ship telemetry reports metrics, not review coverage; it never satisfies a review row.
-- **Content-first rule (diff-scoped rows only: `review`, `adversarial-review`, `codex-review`, ship-stage entries, `design-review-lite`).** Use the helper's computed `review_freshness.status` and show its `reason`. CURRENT requires a completed clean pass with captured start/end wtree equal to the current `---WTREE---`. STALE or UNVERIFIED never clears Eng Review. Missing `review_freshness` is UNVERIFIED, including legacy log-only rows. Never fall back to HEAD equality or commit distance for diff evidence, even at 0 commits. Show recorded cycles, completed/converged state, and missing per-source/phase coverage; unknown is not a pass.
-- Plan-tier rows (plan-ceo-review, plan-eng-review, plan-design-review, codex-plan-review) grade a plan file, not the repo tree — never apply the wtree rule to them; they keep the 7-day freshness logic. If an entry carries `plan_sha256`, you MAY compare it with the plan file and note "plan changed since review" on mismatch.
-- Plan-tier fallback only: parse `---HEAD---`. For entries with a different `commit`, count elapsed commits: `git rev-list --count STORED_COMMIT..HEAD`. If that command FAILS, grade UNKNOWN and treat as stale. Display: "Note: {skill} review from {date} may be stale — {N} commits since review". Missing commit tracking retains the legacy note to consider re-running.
-- If all reviews grade CURRENT, do not display staleness notes
+**4. Display the dashboard.** Show missing, stale, disabled or unavailable results
+explicitly, never as CLEAR. Display a fresh `clean` result as CLEAR and
+`issues_open` as ISSUES OPEN without changing the stored status.

+## Step 11.5: Bind the reviews
+
+1. **Select the two reviews.** Run `~/.claude/skills/gstack/bin/gstack-review-read`.
+   Select this invocation's final Step 9.4 record (`skill:"review"`, `via:"ship"`)
+   and Step 11 native record (`skill:"adversarial-review"`). Match each to its saved
+   handle, original token and source; reject outside-provider or older invocation records.
+2. **Compare their content.** Require the native record's `review_binding.state`
+   to be `verified`. All three snapshots must match: its `wtree`, Step 9.4's
+   `review_binding.start_wtree` and `review_binding.end_wtree`. A mismatch or missing
+   record/field blocks release preparation: report **Review records missing or mismatched**
+   and insert `9 → 10 → 11 → 11.5` before Step 12. Bind the new records at 11.5.
+   Never attach new tokens to old work.
+3. **Preserve any QA exception.** A named probe-risk exception may leave Step 9.4's
+   root `wtree` absent; item 2 still compares its start/end snapshots. Matching content
+   does not mean the failed or unrun probes passed. Keep Step 9.4's incomplete flags
+   and the user's exception.
+4. **Save the evidence.** Save both records and matching **reviewed tree** for
+   Step 16. Continue to Step 12.
+
 ## Step 12: Version bump (auto-decide)
 
-Use **`gstack-version-bump`** for classify/write/repair and `gstack-next-version`
-for slot selection. Bump level and queue collisions remain agent decisions.
+Item 3 needs `BUMP_LEVEL`: reuse this invocation's saved level. Otherwise FRESH
+chooses it in item 2 and ALREADY_BUMPED derives it in item 1.
 
 1. **Classify state** — pure reader, never writes:
    ```bash
    bun run ~/.claude/skills/gstack/bin/gstack-version-bump classify --base <base>
    ```
    Save the JSON `baseVersion` as `BASE_VERSION`, then read `state` and dispatch:
-   - **FRESH** → do the bump (steps 2-4).
-   - **ALREADY_BUMPED** → keep `NEW_VERSION` at `currentVersion`. Reuse this branch's earlier ship decision for `BUMP_LEVEL` if recorded; otherwise compare `baseVersion` and `currentVersion` left to right: the first changed major/minor/patch/micro component supplies `BUMP_LEVEL` (a missing fourth component is zero). Then run step 3's queue check. This recovers the level, not permission to bump again.
-   - **DRIFT_STALE_PKG** → run `gstack-version-bump repair`, then reclassify. On success, follow **ALREADY_BUMPED**, including its queue check; on failure, STOP. Repair alone never re-bumps.
-   - **DRIFT_UNEXPECTED** → **STOP**. package.json disagrees with VERSION while VERSION matches base — a manual edit bypassed /ship. Reconcile manually, then re-run.
+   - **FRESH** → use the recorded level or choose it in item 2, then check the queue and write.
+   - **ALREADY_BUMPED** → keep `NEW_VERSION=currentVersion`. If `BUMP_LEVEL` is missing,
+     use the first changed component from `baseVersion` to `currentVersion`
+     (major/minor/patch/micro; an absent fourth component is zero). Continue at item 3,
+     not another automatic bump.
+   - **DRIFT_STALE_PKG** → run `gstack-version-bump repair`, then reclassify.
+     Success follows ALREADY_BUMPED, including its queue check; failure stops.
+     Repair alone never re-bumps.
+   - **DRIFT_UNEXPECTED** → STOP: package.json disagrees with VERSION while VERSION
+     matches base. Reconcile the manual edit, then reclassify.
 
 2. **Decide the bump level** from the diff (agent judgment):
    - **MICRO**: <50 lines, trivial tweaks/config. **PATCH**: 50+ lines, no feature signals.
-   - **MINOR**: AskUserQuestion for any feature signal (new route/page, migration, new module), OR 500+ lines. **MAJOR**: AskUserQuestion for milestones or breaking changes. Offer the recommended level with rationale, a smaller level, or cancel; wait for the answer. Cancel ends this ship attempt before release writes or push; preserve existing work.
-   Save `BUMP_LEVEL` as lowercase `micro`, `patch`, `minor`, or `major`. Queue placement may advance the slot without changing the intended level.
+   - **MINOR**: ask for any feature signal (new route/page, migration, module) or 500+ lines.
+     **MAJOR**: ask for milestones or breaking changes. Use AskUserQuestion: recommended
+     level with rationale, smaller level, or cancel. Wait; cancel stops before release
+     writes or push and preserves existing work.
+   Save lowercase `BUMP_LEVEL`. A claimed version may move the next available number
+   forward, but cannot change the chosen MICRO/PATCH/MINOR/MAJOR level.
 
 3. **Queue-aware pick** (workspace-aware ship):
    ```bash
    QUEUE_JSON=$(bun run ~/.claude/skills/gstack/bin/gstack-next-version --base <base> --bump "$BUMP_LEVEL" --current-version "$BASE_VERSION" 2>/dev/null || echo '{"offline":true}')
    CANDIDATE_VERSION=$(echo "$QUEUE_JSON" | jq -r '.version // empty')
    ```
-   - **Usable candidate** (including `offline:true` with `fallback:"git"`): print warnings and any claimed queue. FRESH sets `NEW_VERSION` to `CANDIDATE_VERSION`. ALREADY_BUMPED compares it with `currentVersion`; if different, ask to rebump (refresh CHANGELOG/PR title) or keep current (CI rejects a collision). Only approval changes the existing version. An active sibling is a workspace listed in JSON `active_siblings`; use its `branch` and `version`. If one holds `>= NEW_VERSION`, ask to advance past it or stop this attempt and sync.
-   - **No usable candidate** (utility failure or empty result): print queue-unverified; FRESH sets `NEW_VERSION` using local `BUMP_LEVEL` arithmetic, while ALREADY_BUMPED keeps `currentVersion`. Do not follow the usable-candidate instructions above.
+   **Qualify first:** require successful utility output and a nonempty valid version.
+   `offline:false` qualifies; `offline:true` qualifies only with `fallback:"git"`.
+   Offline output without that fallback, failure, malformed output or an empty version
+   is unusable, even if it contains a version-looking string.
+
+   - **Usable candidate:** print warnings and claimed queue. FRESH sets `NEW_VERSION=CANDIDATE_VERSION`.
+     ALREADY_BUMPED compares it with `currentVersion`: if different, ask to rebump
+     (refresh CHANGELOG/PR title) or keep current (CI rejects a collision).
+     Only approval changes the existing version. Check JSON `active_siblings` by
+     `branch` and `version`; a sibling holding `>= NEW_VERSION` requires a choice:
+     advance past it, or stop this attempt and sync.
+   - **No usable candidate:** print queue-unverified. FRESH uses local `BUMP_LEVEL`
+     arithmetic; ALREADY_BUMPED keeps `currentVersion`. Never use an empty candidate.
 
 4. **Write the bump** (FRESH, or an approved rebump):
    ```bash
    bun run ~/.claude/skills/gstack/bin/gstack-version-bump write --version "$NEW_VERSION" --regen-digest
    ```
-   The CLI validates 4-digit `MAJOR.MINOR.PATCH.MICRO` (or 3-digit pinned semver), then writes VERSION, the manifest, and existing `package-lock.json` / `npm-shrinkwrap.json` files; it never creates lockfiles.

Exit 3 means a half-write: reclassify and use `repair` for DRIFT_STALE_PKG.

 **IRON LAW: NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION EVIDENCE.**
 
-Find generation/build commands in CLAUDE.md/AGENTS.md, package scripts, and build
-configuration; run them first, skipping only when none are defined. A failed build blocks push. If it changes tracked files, inspect the
-changes, run affected checks from Steps 6–11, refresh release facts, and commit
-under Step 15 before returning here. Reuse unchanged results and actual approvals.
+Run stages 1–5 in order. Recovery instructions below name where to resume.
+If content changes during or after verification, restart at stage 1 and complete
+all five stages before Step 17. Content-preserving commits keep valid evidence.
 
-Then check test evidence against the final content:
+### 1. Finish writers and prepare outputs
+
+Inspect writer handles, including the docs child. Confirm terminal completion or termination
+before another writer runs. Timeout or cancellation acknowledgment alone means
+STOP until confirmed.
+
+Find declared generation/build commands in project instructions, manifests, build
+files and CI. Run them and save results. If none exists, record not applicable and
+the inspected sources. A missing prerequisite or failed build stops shipping:
+report **Build failed or prerequisite missing**, with the command, error and needed
+repair. Never invent a substitute command.
+**If blocked:** Repair the prerequisite or build, then repeat stage 1. After it passes, continue
+to stage 2; treat any content repair as a behavioral change there.
+
+### 2. Choose the change route
+
+Capture the current tree with `~/.claude/skills/gstack/bin/gstack-wtree`. Inspect
+`git diff <reviewed-tree> <current-tree>` against the snapshot saved before Step 12.
+Missing snapshots block this comparison, regardless of HEAD equality.
+
+Classify the comparison in this order:
+
+1. **Behavior, tests or build inputs changed:** Prompts/templates count as behavior.
+   Insert `5–11.5 → 12–14 → 16` before the pending Step 17, then stop this step.
+   This repair excludes Step 14.5 because the rebuild can change generated docs.
+   Step 16 restarts at stage 1: rebuild and compare again before stage 3 decides
+   documentation freshness. Further repairs use the same work list.
+2. **Only authored docs or release metadata changed:** Keep Step 8's original child
+   report and counts. Recheck affected plan items using their recorded verification
+   and append current evidence to the invocation record. If a classification is no
+   longer supported, run Step 8's audit and decision gates only, then return to
+   Step 16 stage 1. Never edit the child's counts yourself.
+3. **No changes, or the docs-only checks still support the plan:** Continue to stage 3
+   without a new code review.
+
+### 3. Resolve documentation freshness
+
+Compare the base and hashes of the selected release paths, generated
+outputs and docs/templates with Step 14.5's saved values. A prior invocation's
+audit or risk decision never qualifies.
+
+| Outcome | Action |
+|---|---|
+| This invocation's accepted audit matches all inputs | Continue to stage 4. |
+| User-accepted named documentation risk covers the same approved scope and exact content, and unwaivable gates clear | Continue to stage 4; retain `Documentation: blocked`, its reason and incomplete scope. |
+| Missing, stale or blocked | Use recovery below. Never silently refresh hashes. |
+
+Report changed inputs, blockers and attempts used:
+
+- **An attempt remains, with changed inputs or an available repair:** insert
+  `14.5 → 15 → 16` before Step 17. Use Blocked recovery with the existing count.
+  Validate the outcome before Step 15,
+  then restart Step 16 stage 1 to regenerate and compare again.
+- **Otherwise:** STOP unless the user accepts
+  the specific named documentation risk and all unwaivable gates clear, under
+  Step 14.5's Blocked recovery rules. Unchanged approved content goes to stage 4;
+  repaired content goes to stage 1.
+
+Never run a third audit. Child return is not acceptance.
+
+### 4. Verify the frozen candidate
+
+Freeze inputs through verification and push. Run declared docs/link/generated-file
+checks; report unavailable checks.
+
+**Reuse a check when its inputs match.** Compare hashes or complete bytes of its
+saved and current consumed files, fixtures, dependencies and execution parameters.
+Explain why other changes cannot affect it; changed or unknown dependencies require a rerun.
+For model judges, compare the complete expanded request, rubric, parameters and
+builder/runtime dependencies. Reuse identical passing evidence: cite the original
+command, result/counts, timestamp and log, never resample it. Mandatory reviews still run.
+
+**Check each test lane's receipt as well.** Use its actual Step 5 label/command:
+`--label <lane> --expect-cmd '<exact Step 5 command>'`. Inspect changes since the run;
+`--allow-paths` exempts only release metadata. A `package.json` version-only edit
+can qualify; scripts, dependencies and runtime configuration require live tests.
+Uncertain edits cannot be exempted. Docs, TODO edits, new/generated tests and fixes
+make evidence STALE even without a new code review. Use this example only after
+confirming that every allowed edit is release metadata:
 
 ```bash
-~/.claude/skills/gstack/bin/gstack-evidence check --label tests --expect-cmd '<exact tests-lane command from Step 5>' --label vitest --expect-cmd '<exact vitest-lane command from Step 5>' --max-age 24 --allow-paths CHANGELOG.md,VERSION,package.json,agents-digest/gstack-AGENTS.md
+~/.claude/skills/gstack/bin/gstack-evidence check --label tests --expect-cmd '<tests>' --label vitest --expect-cmd '<vitest>' --max-age 24 --allow-paths CHANGELOG.md,VERSION,package.json,agents-digest/gstack-AGENTS.md
 ```
 
-Use only Step 5's actual lane labels and exact commands; `vitest` is an example.
-If Step 4 explicitly declined testing and no lanes exist, report that gap instead
-of inventing FRESH evidence. Build verification still applies.
+| Receipt result | Next action |
+|---|---|
+| FRESH (exit 0) | Cite the label, exit, timestamp and log. |
+| STALE/MISSING: changed content, command or age, or no proven run | Run `~/.claude/skills/gstack/bin/gstack-evidence run --label <lane> -- '<command>'`, read the result and recheck once. Handle failures as described below. |
+| Only receipt storage/readback failed | Independently prove unchanged final content, the same command and valid age from the successful run's evidence. Cite its exact command, exit, timestamp and log as **ledger unavailable**, never FRESH. Without that proof, use STALE/MISSING. |
 
-The allow-list covers release bookkeeping, including Step 12's package/digest
-version stamps. Behavioral package.json edits still require live tests despite
-the path exemption. Do not add `TODOS.md` or generated tests to the allow-list:
-Step 7 tests, review fixes, and Step 14 TODO edits intentionally make evidence STALE.
+No test lanes: require Step 5's explicit untested-scope approval for final content,
+or run Steps 5–15, including the no-tests decision, then return to Step 16 stage 1.
+Report the gap, never FRESH; builds must pass.
 
-- **Every line FRESH (exit 0):** recorded runs passed on identical content except
-  the listed release files. Cite label, exit, timestamp, and log path; continue.
-- **Any STALE/MISSING (exit non-zero):** inspect the reason before choosing recovery:
-  - **Content, command or age mismatch, or no passing live evidence:** rerun the
-    affected lanes on final content, wrapped as `~/.claude/skills/gstack/bin/gstack-evidence run --label <lane> -- '<command>'`.
-    Read results and recheck once. TODO edits and generated tests are content
-    changes, not ledger-only bookkeeping.
-  - **Ledger read/write failure only:** if a successful live run already covers
-    the unchanged final content, exact command and permitted age, cite its exit,
-    timestamp and log directly. Report ledger unavailable and continue, never
-    ledger FRESH. Do not rerun green suites solely because the ledger cannot save
-    or read its record. If unchanged content cannot be confirmed, STOP.
+**New, changed or unwaived test failure:** STOP publication. Run Steps 5–15,
+starting with Step 5's triage, then return to Step 16 stage 1. This recovery also
+applies if a failure appears while reporting in stage 5. Reentry to Step 14.5
+keeps its existing audit count; it does not authorize a third attempt.
 
-A failed CHECK identifies evidence to repair; it is not a test failure. The
-required live RUN must pass, except for the explicit triage waiver below.
+### 5. Report, then push
 
-Paste build and rerun results. Later code, test, or build-input changes return
-through this gate before pushing. Step 18 owns validation of its post-push
-docs-only edits; follow repository-required checks there too. Do not claim an
-earlier test run covered changed inputs.
+Commit only approved, verified release changes left uncommitted after Step 15,
+including generated outputs; use its grouping rules and never create an empty commit.
+Preserve unrelated user files.
 
-**If tests fail here:** apply Step 5's triage. A prior explicit waiver remains valid
-only for the same verified pre-existing failures and approved scope; cite that
-approval and actual failing counts, never FRESH or all-green evidence. New,
-changed, or unwaived failures STOP publication and return to Step 5.
-
-Claiming work is complete without verification is dishonesty, not efficiency.
+Paste build/docs/test results. Reuse waivers only for the same verified
+pre-existing failures and approved scope; cite the actual approval and failing
+counts, never FRESH or all-green. A new, changed or unwaived test failure uses
+stage 4's recovery before publication. Otherwise continue to Step 17.

-**PR/MR title invariant (always applies — do not skip even if you don't open the section below):** Any PR or MR you create OR update in the next step MUST have a title that starts with `v$NEW_VERSION` (the version bumped in Step 12), in the format `v<NEW_VERSION> <type>: <summary>`. Never create or edit a PR/MR title without this prefix. Compute the correct title with the single source of truth helper: `~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh "$NEW_VERSION" "<current title>"`. The full create/update procedure (idempotency, redaction scan, self-check) is in the section below.
+## Step 18: Prepare publication metadata
 
-**Doc-sync invariant (always applies — do not skip even if you don't open the section below):** Step 18 dispatches the /document-release subagent BEFORE the PR/MR is created or updated in Step 19. Never skip the dispatch itself; only a failed subagent is non-blocking (proceed to Step 19 without a `## Documentation` section).
+First look up open PRs/MRs for `<branch-name>` on the detected platform:
 
-> **STOP.** Before dispatching the /document-release subagent to sync docs (Step 18) and then creating or updating the PR/MR (Step 19), Read `~/.claude/skills/gstack/ship/sections/pr-body.md` and execute it

+- GitLab: `glab mr list --source-branch <branch-name> --output json` (defaults to open).

+2. For a new PR/MR, compose `v<NEW_VERSION> <type>: <summary>`.
+3. Save the result as `NEW_TITLE` for Step 19. Every created or updated title MUST

 ## Step 20: Persist ship metrics
 
-Log coverage and plan completion for `/retro` through `gstack-review-log`.
-It resolves the project/branch, validates JSON, creates storage and queues sync.
-It takes **no path argument**: hand-built `<branch>-reviews.jsonl` paths break
-branches containing `/`.
+Log metrics for `/retro` through `gstack-review-log`; it handles project/branch paths,
+JSON validation, storage and sync. It takes **no path argument**; do not build one.
 
 ```bash
 ~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"ship","timestamp":"'"$(date -u +%Y-%m-%dT%H:%M:%SZ)"'","coverage_pct":COVERAGE_PCT,"plan_items_total":PLAN_TOTAL,"plan_items_done":PLAN_DONE,"verification_result":"VERIFY_RESULT","version":"VERSION","branch":"'"$(git rev-parse --abbrev-ref HEAD)"'"}'
 ```
 
 Substitute from earlier steps:
-- **COVERAGE_PCT**: coverage percentage from Step 7 diagram (integer, or -1 if undetermined)
+- **COVERAGE_PCT**: Step 7 diagram's integer percentage; encode null/undetermined as -1
 - **PLAN_TOTAL**: total plan items extracted in Step 8 (0 if no plan file)
 - **PLAN_DONE**: count of DONE + CHANGED items from Step 8 (0 if no plan file)
-- **VERIFY_RESULT**: "pass", "fail", or "skipped" from Step 8.1
+- **VERIFY_RESULT**: "pass", "fail", or "skipped", set after Step 9 executes Step 8.1's verification list
 - **VERSION**: from the VERSION file
 
-The branch name is filled in by the shell — there is no `BRANCH` placeholder to
-substitute.
-
-This step is automatic — never skip it, never ask for confirmation.
+The shell supplies the branch. Run this automatically, without confirmation.
 
 ---
 
 ## Step 21: Plan-tune discoverability nudge (first-successful-ship only)
 
-Plan-tune cathedral T15. After a successful ship, surface /plan-tune once
-per machine. Single line, non-blocking, marker-gated so it never re-fires.
+After a successful ship, show the non-blocking /plan-tune nudge once per machine:
 
 ```bash
-_NUDGE_MARKER="$HOME/.gstack/.plan-tune-nudge-shown"
+eval "$(~/.claude/skills/gstack/bin/gstack-paths)"
+export GSTACK_STATE_ROOT
+_NUDGE_MARKER="$GSTACK_STATE_ROOT/.plan-tune-nudge-shown"
 _QT=$(~/.claude/skills/gstack/bin/gstack-config get question_tuning 2>/dev/null || echo "false")
 if [ ! -f "$_NUDGE_MARKER" ] && [ "$_QT" = "false" ]; then
   echo ""
   echo "gstack can learn from your AskUserQuestion answers. Run /plan-tune to opt in"
   echo "— it captures which prompts you find valuable vs noisy and (with hooks installed)"
   echo "auto-decides your never-ask preferences."
-  touch "$_NUDGE_MARKER"
+  mkdir -p "$GSTACK_STATE_ROOT" && touch "$_NUDGE_MARKER"
 fi
 ```
 
-If the marker exists, OR question_tuning is already on, the nudge is a
-no-op. The marker guarantees at-most-once per machine. To re-enable:
-`rm ~/.gstack/.plan-tune-nudge-shown` before next ship.
+The marker or enabled question_tuning suppresses it. To re-enable, remove
+`$GSTACK_STATE_ROOT/.plan-tune-nudge-shown` before the next ship.
 
 ---
 
 ## Section self-check (before you finish)
 
-You ran a carved skill. For your situation, list every section the Section index
-named as applying, and confirm you issued a Read for each one. If you executed any
-of those steps from memory without reading its section, you skipped the source of
-truth — STOP, Read it now, and redo that step. Deterministic version work goes
-through `gstack-version-bump`; never hand-roll the VERSION/package.json write.
+List the applicable Section index entries and confirm each Read. If you worked from
+memory, STOP, Read the section and redo that step. Use `gstack-version-bump`, never
+hand-roll VERSION/package.json writes.
 
 ---
 
 ## Important Rules
 
-- **Never skip tests.** If tests fail, stop.
-- **Never skip the pre-landing review.** If checklist.md is unreadable, stop.
+Follow the numbered gates and their explicit exceptions.
+
 - **Never force push.** Use regular `git push` only.
-- **Never ask for trivial confirmations** (e.g., "ready to push?", "create PR?"). DO stop for: version bumps (MINOR/MAJOR), pre-landing review findings (ASK items), and Codex structured review [P1] findings (large diffs only).
 - **Always use the 4-digit version format** from the VERSION file.
-- **Date format in CHANGELOG:** `YYYY-MM-DD`
-- **Split commits for bisectability** — each commit = one logical change.
-- **TODOS.md completion detection must be conservative.** Only mark items as completed when the diff clearly shows the work is done.
-- **Use Greptile reply templates from greptile-triage.md.** Every reply includes evidence (inline diff, code references, re-rank suggestion). Never post vague replies.
-- **Never push without fresh verification evidence.** If code changed after Step 5 tests, re-run before pushing.
 - **Step 7 generates coverage tests.** They must pass before committing. Never commit failing tests.
-- **The goal is: user says `/ship`, next thing they see is the review + PR URL + auto-synced docs.**

Neither term permits repairs.\n41\t\n42\t## Section index \u2014 Read each section when its situation applies\n43\t\n44\tRead sections in full when directed; do not work from memory.\n45\t\n46\t| When | Read this section |\n47\t|------|-------------------|\n48\t| running selected report-only baseline and exploratory probes without product or test writes | `sections/exploratory.md` relative to the installed `qa-only`/`gstack-qa-only` SKILL.md directory |\n49\t| finalizing the report after probing stops | `sections/reporting.md` relative to the installed `qa-only`/`gstack-qa-only` SKILL.md directory |\n50\t\n51\tStart at Request Parameters, not the index; load shared QA methods before exploration.\n52\t\n53\t## Request Parameters\n54\t\n55\t**Parse the user's request for these parameters:**\n56\t\n57\t| Parameter | Default | Override example |\n58\t|-----------|---------|-----------------:|\n59\t| Target | (infer from request/repository or ask) | Browser URL, API route, CLI command, job, worker or webhook |\n60\t| Mode | full | `--quick`, `--regression <previous-report-or-baseline>` |\n61\t| Output dir | `.gstack/qa-reports/` | `Output to /tmp/qa` |\n62\t| Scope | Selected target (or diff-scoped) | `Focus on duplicate webhook delivery` |\n63\t\n64\tUse an isolated synthetic identity for functional probes. For browser sessions,\n65\tfollow Browser Setup; never request credentials in chat.\n66\t\n67\tParsing records the request; it does not start browser setup. If both `--quick` and\n68\t`--regression` are supplied, ask the user to choose one mode before setup or probes.\n69\t\n70\t**On a feature branch without an explicit scope:** Use diff-aware testing of changed\n71\tand adjacent behavior. Do not discover a browser merely because no URL was supplied.\n72\t\n73\t## Test Plan Context\n74\t\n75\tLook for a test plan in this conversation. If this session already knows the\n76\tproject's state directory, also Read its newest `*-test-plan-*.md` when permitted.\n77\tDo not create state or run bookkeeping helpers just to find optional context.\n78\tPrefer the plan covering more selected contracts; break ties by recency.\n79\tIf neither exists, use git diff analysis.\n80\t\n81\t## Prior Learnings\n82\t\n83\tRead this project's existing learnings.jsonl only if its directory is already known\n84\tand the caller permits that Read. Otherwise skip this optional lookup.\n85\tDo not run gstack-learnings-search here: its slug helper can update a cache.\n86\tDo not change configuration, enable cross-project search or create a learning store.\n87\t\n88\tTreat old notes as leads, not proof. When a QA finding matches a past learning,\n89\tcite it as \"Prior learning applied: [key] (confidence N/10, from [date])\" and verify\n90\tthe current behavior. Reading old notes never requires writing new ones.\n91\t\n92\t## Select Surfaces and Isolation\n93\t\n94\tRead `sections/scope.md` relative to the installed `qa`/`gstack-qa` SKILL.md directory in full. Find qa/gstack-qa beside this host's installed caller skill. If missing or unreadable, report a QA setup blocker and its affected probes as blocked; continue other safe probes (independent functional/static checks). Missing/unreadable assets block required QA. No product-directory or cross-host substitutes.\n95\t\n96\tEach surface's method defines Full, Quick and Regression. A mode flag applies to all\n97\tselected surfaces unless the request names one surfaceLine truncated

Started 2026-09-27T10:01:12Z, ended 10:01:34Z (2 probes, ~22s of 5 min / 12 budget).\nIsolation: pure-function imports; no network, env secrets, or durable writes. Checkpoints kept outside the repo to keep the captured candidate unchanged.\n\n| # | Contract | Probe | Expected | Outcome |\n|---|---|---|---|---|\n| 1 | Successful execution — shared helper contract (test/retry-after.test.ts) | `bun test` | 1 pass, exit 0 | **pass** (1 pass / 0 fail / 5 expects, exit 0) |\n| 2 | Successful execution + invalid input — worker copy equivalence with lib and route (null, invalid, trimmed seconds, ceiling, HTTP-date, past date→0, unsafe int→fallback, whitespace→fallback, empty→fallback) | see exploration-001.json nextCommand | identical outputs for all 9 inputs, exit 0 | **pass** (mismatches: 0, exit 0) |\n| – | Auth, CLI process, state transitions, timeout, retry loop, idempotency, concurrency, partial failure | – | – | not applicable — diff is a pure parsing function with no I/O, state or scheduling |\n\nCheckpoints: charter.md, exploration-001.json (this directory).\nFindings: none. Coverage gap (not a defect): the worker's inline copy has no test of its own; equivalence proven only by probe 2, which is invocation-local.\nTest proposals: none required — adopting the shared helper (re-export) puts the worker back under test/retry-after.test.ts coverage.\nCleanup: nothing to clean (no owned processes/state). /tmp/qa-p1.err, /tmp/qa-p2.err are stderr captures only.\n"

+This native-parent fixture supplies a deterministic child transport instead of Agent/Task. It is a host adapter, not a replacement workflow. Do not invoke real Agent/Task or execute the child's audit/lifecycle yourself. Read the actual phase and its installed documentation section and child assets. The adapter returns child evidence; only you apply the loaded workflow's gates.
+
+Declared transport interface (literal key=value arguments; quote file paths as needed):
+bun ${actorFile} prepare ${stateFile} audit_id=ID
+bun ${actorFile} dispatch ${stateFile} audit_id=ID candidate=ABSOLUTE_JSON_PATH prompt=ABSOLUTE_PROMPT_PATH run_in_background=false
+bun ${actorFile} inspect ${stateFile}
+bun ${actorFile} status ${stateFile} task_id=RETURNED_TASK_ID
+bun ${actorFile} stop ${stateFile} task_id=RETURNED_TASK_ID
+${docsActorCanRepair(scenario) ? `bun ${actorFile} repair ${stateFile}\nThis launcher supports one concrete marking/transport repair, only after a dispatched child is confirmed settled. That isolated repair is authorized, not approval for document risks.` : 'This launcher has no repair operation or alternate launcher. Missing assets/marking, launch failures and invalid completions cannot be repaired here. Do not invoke repair or invent an inline fallback.'}
+bun ${actorFile} publish ${stateFile} audit_id=ID report=${report}
+
+prepare is a serialization convenience, not an audit or validation: after inspecting the required inputs and deciding an attempt is allowed, supply a fresh id of 1–80 letters/digits/underscores/hyphens, beginning with a letter or digit. It saves current base/HEAD/index, selected paths, dirty paths, docs roots and content hashes to a new candidate JSON, and copies the exact installed section's child prompt with literal substitutions and the observation interface to a new prompt file. It returns their paths. Read these artifacts; use the returned paths unchanged in dispatch. prepare neither launches a child nor resets/increments the attempt count, repairs content, compares snapshots or accepts an audit. Saved files are never overwritten. Use the single batched inspect transport call (declared above) to read committed, staged, unstaged and new content in one response instead of one command per file.
+
+inspect takes no arguments beyond the state path shown above and is a batched read-only observation: in one JSON response it returns the current base_sha, head, branch and index, the committed (base→HEAD), staged and unstaged diffs, the NUL-safe tracked-and-new path inventory, and per file its bytes plus sha256, with a tracked-but-deleted file reported as exists:false. It returns no verdict, acceptance, snapshot refresh, attempt, count change or publication, never exposes private transport state or precomputed gate answers, and grants no repair, risk exception, new attempt or missing-asset bypass; you still parse the returned data and apply every gate yourself. It is a real observation boundary: an independent editor may change inputs exactly at inspect time, as during any repository read, so an inspect after the child can legitimately reveal a changed input that invalidates a returned audit. Read the actual phase, the installed documentation section and the child assets directly; inspect does not substitute for those reads.
+
+Parent output handling (stay inside the declared interface; do not add shell to it):
+1. Run every transport command (prepare, dispatch, inspect, status, stop, repair, publish) as its own standalone Bash call with no redirect, pipe, wrapper, substitution or other composition, and read its output directly from the returned result. Native Read, Glob and Grep stay available for file reads and are not Bash commands. Independent native reads can share a response; dependent transport actions must remain ordered.
+2. Keep inspect observations in their original tool results in context and compare those returned values directly. Do not transcribe or reserialize inspect JSON into duplicate snapshot files; prepare already saves the required candidate and prompt. Never redirect a command into a file and never re-run a command merely to save its output. Compare the returned base/head/index/sha256/content/diff fields and the required asset Read results in your own reasoning. Use only the transport commands above and the commands permitted by the Fixture observation interface below; do not introduce any undeclared comparison or processing program to compare or transform observations, even read-only.
+3. Persist each required checkpoint as one short appended journal entry, not a rewritten record or separate edits for each field. After reading the invocation record, use native Edit with old_string exactly ${JSON.stringify(DOCS_CHECKPOINT_MARKER)}, new_string containing only the new entry followed by that same marker, and replace_all=false. The marker must occur exactly once; if missing or duplicated, stop rather than guessing an edit. Preserve unrelated sections and every earlier entry byte-for-byte, retaining each earlier attempt's id, count, evidence paths and outcome. The latest stated value is current; do not recopy previous entries. Each entry states the current attempt count, newly learned decision/evidence and next required action. Reference saved candidate/prompt/completion artifacts instead of repeating their contents or prior narration. Before dispatch, save the incremented attempt count, fresh audit id and candidate/prompt paths together. Save the returned child handle before polling; consolidation must never postpone the pre-launch count or child-settlement checks.
+4. After the child, preserve each actual child completion/rejected output once in Markdown as the bounded-stage interface requires. Compare the saved snapshot with current files and apply the loaded output, ownership and freshness gates. If recovery is authorized, save the intermediate result in one checkpoint before continuing it. Otherwise use the finishing checkpoint below, not an extra status-only update. A changed input requires the workflow's fresh attempt, never silently replaced hashes. Recheck freshness again before publication.
+5. After the loaded Continue or recover / Blocked recovery steps reach a final outcome, finish the required invocation state and final report before optional narration or formatting. Append status, reasons, evidence paths, pending work and any accepted post-child hashes/documentation_section in one finishing entry; do not repeat earlier gate analysis or split that known outcome across multiple edits. Append the finishing checkpoint and Write the complete report in the same response using separate native file calls, then return briefly after any authorized publication receipt. Follow the loaded gate order: when it requires stopping, write the required invocation state and report, then stop rather than continuing later preparation to fill optional artifacts. Never omit the final report or final response, even when publication is blocked.
+
+dispatch returns terminal final text, a launch error, or a running task_id. Terminal final text means that child is settled. A launch error saying no child started is authoritative and returns no task handle: do not probe invented ids. Use status/stop only with an actual returned task_id. The virtual clock advances to the next policy deadline on each status query; do not sleep. A stop request alone is not settlement or permission to publish. An independent fixture actor may change selected source between phases. Do not read/edit ${stateFile}; it is private transport state. Only when the actual workflow permits publication, call publish, a local receipt rather than GitHub.

+  return `Fixture observation interface (applies to parent and every child; include this interface in child prompts): Bash may execute only separate literal pwd, ls, cat, stat, sha256sum, Git read commands (status, diff, show, log, ls-files, rev-parse, merge-base, hash-object without -w, branch --show-current), the exact generated Preamble block with its spawned prefix, or literal installed gstack-skill-start/gstack-skill-end commands for document-release (start requires GSTACK_SESSION_KIND=spawned). No shell composition, custom interpreters, arbitrary scripts, inline eval or memory-mapped writes. The only additional scripts are ${scripts.length ? scripts.join(', ') : 'none'}. Read/Glob/Grep remain available. Use Write/Edit for permitted docs and private JSON/Markdown artifacts under ${fixture.home}; 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 ${fixture.repo}. Run Git reads directly, for example: git status, git diff --cached, git merge-base main HEAD, git rev-parse HEAD. Do not use Git global options such as -C, -c, --git-dir or --work-tree, and do not prepend cd or another shell wrapper. The literal git subcommand must immediately follow git; an absolute owned repository path does not make git -C an allowed command.
+
+Platform: local/git-native. Base: main. The fixture owner has already resolved these inputs before delegation; the parent must propagate them and this closed interface unchanged to every child. Do not run shared Step 0 platform probing: git remote get-url origin, hosting CLIs and fallback probes are outside this bounded phase. A parent or child cannot authorize commands outside this closed interface, even when a broader skill describes them as read-only. Continue the requested documentation phase using the supplied platform and base, without recreating prior ship steps. Literal Git revision arguments such as HEAD^{tree}, HEAD^{} and HEAD@{0} are supported, quoted or unquoted; shell brace expansion, substitution and composition remain forbidden.
+
+${transport ? 'Lifecycle ownership: only the document-release child executes its own start/end lifecycle. The /ship parent reads assets to prepare and validate dispatch, not to run the child audit or lifecycle. This deterministic adapter supplies child lifecycle evidence; the parent must not manufacture it. The following lifecycle commands describe the child, not parent work.\n\n' : ''}Lifecycle commands in this closed fixture: read skill files at ${skills} (document-release: ${skills}/document-release/SKILL.md). Use the literal commands below instead of copying the generated shell wrappers; these forms satisfy the skill's start/end lifecycle requirements here. Run each as a separate, single-line Bash call. Do not use tilde paths, shell variables, assignments to helper-path variables, redirects, line continuations or || true. Do not add a parent PID: the start helper supplies its default.
+
+Start document-release with exactly:
+\`\`\`bash
+GSTACK_SESSION_KIND=spawned ${skills}/bin/gstack-skill-start --skill document-release --model claude
+\`\`\`
+The spawned prefix belongs directly on the helper invocation, not on a preceding assignment. Read the returned SESSION_KIND, SESSION_ID and TEL_START status lines. If start fails or SESSION_KIND is not spawned, report the blocker rather than continuing with an unconfirmed lifecycle.
+
+At workflow completion, use this one-line end command. Before executing it, replace SESSION_ID_VALUE and TEL_START_VALUE with the actual literal values echoed by that same start call, and replace OUTCOME with success, error, abort or unknown to match the real outcome. Never execute the placeholders or reuse values from another session.
+\`\`\`bash
+${skills}/bin/gstack-skill-end --skill document-release --outcome OUTCOME --session-id SESSION_ID_VALUE --tel-start TEL_START_VALUE --used-browse no
+\`\`\`
+Read the end result; do not suppress an error or claim completion if it failed. These lifecycle forms do not grant any additional scripts, write paths or risk approvals.`;

This excerpt comes from ${fixture.runtime}/${fixture.caller}/SKILL.md; resolve installed-relative references there, not from the excerpt file or product directory. That path identifies the asset base, not another entrypoint: do not read or invoke the full parent SKILL.md or rerun its preamble. Earlier preamble/branch/base setup is complete; use the existing local origin/main ref without fetch. Earlier-phase asset locators are ${fixture.runtime}/review/checklist.md and ${fixture.runtime}/qa/templates/functional-report-template.md. Read those files directly when referenced; recursive Glob does not follow the installed asset symlinks. Cross-project learnings are configured off in this owned fixture. ${fixture.reviewStart ? `The actual review-start helper already captured REVIEW_START=${fixture.reviewStart} for this unchanged core pass; retain that token. ` : ''} This fixture evaluates only the supplied parent phase, not later publication stages. Read README.md for the project contract and commands. Use diagnostic-client commands such as \`bun scripts/probe.ts <literal>\` for exploratory discoveries and their checkpoint evidence. A required \`bun run test\` is separate suite verification: report it as verification, never as a diagnostic observation or checkpoint anchor/target. Use the production evidence helper to publish each diagnostic checkpoint as \`reports/exploration-NNN.json\`, not inside a nested directory; do not transcribe its observed payload. ${fixture.caseId === 'ship-exploratory-plan-checks' ? 'The previously discovered plan is PLAN.md.' : 'No plan file was found.'} There is no remote service and no release publication is authorized. There is no interactive approver; do not invent answers or permission. Keep normal parent decision gates. Before every completion report or bookkeeping log, read HANDOFF.md and reports/HANDOFF.md if present for any concurrent collaborator update, await the results, and compare evidence with current inputs. A gstack-review-log completed:true record is a completion, not preliminary bookkeeping; a later handoff read cannot validate an earlier completion.\n\nDeadline bookkeeping additionally permits \`bun ${fixture.runtime}/bin/gstack-qa-deadline start ${fixture.cwd}/reports/deadline.json SECONDS [EARLIER_UTC]\`, \`bun ${fixture.runtime}/bin/gstack-qa-deadline status ${fixture.cwd}/reports/deadline.json\`, and \`bun ${fixture.runtime}/bin/gstack-qa-deadline run ${fixture.cwd}/reports/deadline.json -- bun scripts/probe.ts [literal]\`. These are closed literal forms: SECONDS must be positive and at most 300, EARLIER_UTC is the optional caller absolute deadline: use the section clock's Hard deadline UTC, never its Runner entry UTC, reserve-start time or a clock-read time. The child is only the existing diagnostic client with zero or one literal argument. Resolve these exact helper and state paths; do not use variables, another helper, another state file, nested wrappers, scripts, operators or substitutions. Only this helper may create or change reports/deadline.json and its .qa-deadline- temporary files; never use Write/Edit/MultiEdit on those paths. Record the full outer run command in checkpoints and evidence; keep the unchanged child JSON as observed, separate from prefixed guard diagnostics. A completed expired guard-run is not a probe or a pass: retain its unused checkpoint, report not-run coverage and do not restart the deadline. Keep the 12-probe smoke limit. Required suites and explicit plan checks are outside the bounded smoke budget, not permission to reset it.\n\nFunctional evidence uses the same production helper and existing diagnostic client: \`bun ${fixture.runtime}/bin/gstack-qa-evidence capture ${fixture.cwd}/reports NNN --public --deadline ${fixture.cwd}/reports/deadline.json -- bun scripts/probe.ts [literal]\`. These diagnostic receipts are declared public/synthetic, so --public is approved; a fresh three-digit ID is required each time. Explicit plan probes outside the smoke budget may replace --deadline with --timeout-ms 10000; this does not reset or bypass the smoke deadline. Publish causal intent with \`bun ${fixture.runtime}/bin/gstack-qa-evidence checkpoint ${fixture.cwd}/reports NNN CAPTURE_ID 'full prior capture command' 'causal hypothesis' 'full next capture command'\`; quote arguments literally. For complex quoting, Write only capture, observationCommand, hypothesis and nextCommand to reports/intent.json; publish with the same helper: checkpoint REPORT_ROOT NNN intent.json. Materialize is supported when evidence.json is required. Sources stay inside reports. Decide to execute the next probe before publishing its checkpoint, then await successful publication and dispatch that exact probe. If you defer an optional idea or stop exploration, do not publish a checkpoint for it; descri

All four reads are required before probing in this fixture, even when its surfaces and isolation are already established. This is a CLI/webhook product, not a browser or DX request. The generated local skill copies are the current evaluation inputs; all their installed-root references resolve inside this fixture.

+The fixture README and AGENTS define intended contracts, native tests and owned state. Investigate behavior without assuming implementation correctness. Establish a happy path${entry.family === 'cli' ? ' with a successful apply; balance alone is not enough' : ''}. Choose adverse probes from observations, reproduce discoveries, and obey the skill's mutation authority. Use the production capture/checkpoint helper for every native probe and checkpoint: you supply causal intent; it preserves complete unchanged native JSON in observed. Tests, source edits and clock reads do not replace that observation; put red/green test output in the report, not in observed. Retain each note under qa-reports, wait for successful checkpoint publication before the next probe, and link the notes in the final report; write no checkpoint when there is no next probe. No defect is disclosed here.

+3. Save the evidence and Markdown artifacts, then return their paths and the actual completion status.
+
+The completion reserve is for both required verification and artifacts, not a signal to stop stage 2: the completion reserve does not end required coverage. Stop only exploration beyond the required contracts to protect that work. If required verification remains unfinished at the hard deadline, report incomplete; do not call it complete with a caveat.` : ''}
+
+Use one causal sentence per checkpoint hypothesis (English, more than 20 characters) and compact JSON formatting, preserving every field and value. Keep the Markdown report compact (aim under 400 words, excluding actual test output): retain its headings and required fields, but link to evidence.json and checkpoints for details already recorded there. Include the diagnosis, ${entry.mode === 'qa' ? 'red/green test results' : 'proposed test stubs'} and coverage limits; do not repeat the evidence table or add a second PR summary. After saving both artifacts, return only their paths and the actual completion status, not another copy of the report. Never shorten native JSON or omit a required probe, check or field to meet this presentation target.
+
+Fixture execution boundary:
+- No prior plans, global learnings, remote or cross-session artifact store. Branch/base are main, with a clean successful seed commit. Do not run global setup, telemetry, plan discovery, base-detection scripts or learning writes.
+- Reports belong only in existing qa-reports. Retain fixture state; the owner cleans it after preserving evidence. Authorized source/test edits use Write/Edit. Read/Glob/Grep support arbitrary read-only discovery, including directory/path inventory.
+- Bash accepts separate literal commands only: no shell composition, scripts or added path operands. Read-only forms are pwd, ls, ls -la, git status --short, git status --porcelain, git branch --show-current, git diff, git diff --stat, git rev-parse HEAD, bun --version, and exactly date -u +%Y-%m-%dT%H:%M:%SZ. Native tests use bun test with optional named test/*.test.ts selectors.
+- These are complete command forms, not general shell examples. For inventory inside a named directory, use Read/Glob/Grep; the listed ls forms inspect only the working directory. Do not add operands or flags beyond the declared forms, even for read-only discovery.
+- The installed production helper is bin/gstack-qa-evidence (absolute owned path also accepted). Probe outputs are declared public/synthetic, so capture with: bun bin/gstack-qa-evidence capture qa-reports NNN --public --timeout-ms 10000 -- NATIVE_PROBE. The child must be one of the observation forms below. Each execution/replay gets a fresh three-digit ID. The helper does not authorize another command, interpreter, path, pipeline or redirect.
+- Publish causal intent from the most recent completed native probe with bun bin/gstack-qa-evidence checkpoint qa-reports NNN CAPTURE_ID 'full prior capture command' 'causal hypothesis' 'full next capture command'; quote each argument literally. For complex quoting, Write only capture, observationCommand, hypothesis and nextCommand to qa-reports/intent.json, then use bun bin/gstack-qa-evidence checkpoint qa-reports NNN intent.json. Wait for successful publication before dispatching the exact next command. Only the helper writes observed fields.
+- Write annotations.json inside qa-reports, then run bun bin/gstack-qa-evidence materialize qa-reports annotations.json to produce evidence.json before writing Markdown. Annotations have revision, runtime, cwd, evidence rows {capture,command,contract,expected,classification}, learning (selected checkpoint IDs) and limits; omit observed, which the helper supplies from captures. In each evidence row, capture is the three-digit capture ID and command is the exact full outer capture invocation, including that ID and all wrapper options, not just the native child command after --. This same full-command definition applies to observationCommand and nextCommand. Select a checkpoint whose next native command differs, not a same-command replay with a new capture ID. Retain all required safe observations and every executed probe.
+- ${entry.family === 'cli' ? 'CLI observation forms: bun run probe -- balance; bun run probe -- export; bun run probe -- apply with zero to three literal arguments; bun cancel.ts. The equivalent bun run cli commands may be diagnostic but do not emit probe JSON. Arguments use ASCII letters/digits/._+- or quoted forms including spaces. The generic wrapper does NOT support wait: the only bounded wait/cancellation interface is bun cancel.ts.' : `Webhook observation form: bun run probe -- followed by one of happy, reject, duplicate, partial, concurrent-ab, concurrent-ba, cancel, dependency. ${entry.mode === 'qa-only' ? 'All eight scenarios are required coverage; a replay does not replace another scenario. ' : ''}Choose their order from observations after the happy path. bun cancel.ts is a CLI-only entrypoint, not part of this fixture.`}
+Actions outside this interface are unsupported and fail acceptance; they are not implicitly approved.
+
+Materialize qa-reports/evidence.json first, then write a concise qa-reports/report.md using the functional report structure. Link the evidence and checkpoint files rather than repeating full probe payloads in Markdown. Both artifacts are required before completion. The resulting evidence.json schema is:
+{ "revision": "<git HEAD>", "runtime": "bun <version>", "cwd": "<working directory>", "evidence": [{"command":"<exact full outer capture invocation>","contract":"README.md","expected":"<declared expected behavior>","classification":"pass|product-defect|setup-blocked|inconclusive","observed":<complete unchanged JSON emitted by the native probe>}], "learning":[{"observationCommand":"<earlier full capture invocation>","hypothesis":"<what it taught you to challenge>","nextCommand":"<later full capture invocation>"}], "limits":["<untested or blocked coverage>"] }
+Evidence rows contain ONLY complete JSON actually emitted by native probes, including failures and repeats; retain pre-repair results alongside green results. Never synthesize JSON from a tool error or raw test output. Put tests, raw CLI diagnostics, launch failures and timeouts in Markdown with their actual output and limits. The learning array is a summary: choose one completed checkpoint where an observation motivated a different later command, not the required same-command replay. Select that checkpoint ID in annotations.learning; the production helper copies its observationCommand, hypothesis and nextCommand. Both commands must name exact captured probes with different native child commands, never a combined command list or a replay distinguished only by capture ID. This selects existing exploration evidence, not another probe or a duplicate of the complete checkpoint ledger. Preserve every checkpoint and link every checkpoint in Markdown; keep every executed probe and its complete JSON in evidence, including the required replay. Missing dependencies remain setup blockers, not repairs. No browser installation or execution is needed.`;

The actor cannot complete core/checklist review, approve edits, answer decision questions or establish convergence for you. Apply the production COMPLETED/CONVERGED rules to your own work plus the current supplied results; never ask the question actor to override completion.
+5. In the final QA/verification summary, identify the actor results as simulated fixture-stage interactions, not actual QA or native adversarial execution; they receive no actual native coverage credit.

+- Out of scope: do not audit helper or lib implementations, read the fixture request logs, enumerate the bin/lib/review/qa roots, probe --help or other CLI options, or review unrelated history.
+- Still inspect the target repository source, Git configuration and attributes, actual snapshot coverage, and the prior and final persisted review records the workflow requires.
+- To stay within the turn budget, batch independent reads into as few Read or Bash calls as correctness allows, but keep receipt-ordered commands separate and in order: capture the start token before reading the diff, and run --start, the checker and any declared stage-actor invocation each as its own sole command. The only combined receipt call is the final persistence: run \`gstack-review-log '<record>' --finish REVIEW_START\` and, only after it succeeds, its full \`gstack-review-read\` read-back in that same call.
+Execute the included workflow, including its real start captures, decision questions, ${resumed && !('actorCommand' in resumed) ? 'zero-edit convergence checks' : 'any approved edits, convergence checks'} and final review record. The user will answer AskUserQuestion. This is a code review, not a standalone recent-history audit.

 Revalidation fixture execution contract:
-- The runtime allows ${SHARED_INTERACTIVE_MAX_TURNS} assistant turns. Batch independent required source reads, Git configuration/attribute checks, and snapshot checks within each phase. Preserve every required evidence check and dependency: capture the real start token before reading the diff, and complete final evidence verification before persistence.
-- The trusted start-record location is ${startRecord}. Replace <REVIEW_START> with the token actually returned by --start. Read that token's record in a separate, successful Read tool call or a single cat command before continuing. Verify its repo, branch, working tree and start time. Do not combine the record read with --start, the diff or other diagnostic commands whose failure could invalidate the read; if the read fails, retry it before proceeding. Use the supplied helper interfaces; discovering helper CLI options is outside this replay.
-- After final verification, combine successful --finish persistence and one complete, untruncated read-back through gstack-review-read in the same tool invocation. Read back only after persistence succeeds, inspect the full current record and binding, then return the final review summary in conversation.
+The runtime allows ${SHARED_INTERACTIVE_MAX_TURNS} assistant turns. Batch independent required source reads and other Git/configuration/attribute inspections only outside the receipt commands below. Preserve every required evidence check and dependency. This is a closed transport interface, not permission to omit workflow stages.
+
+1. Gather base metadata first. From the target repo, run the following as the sole command in its Bash call. Its stdout must contain only the token: no echo, labels, status, diff or other commands. Do not read the diff until step 2 verifies the start record; preserve Step 3's start-before-diff order.
+
+\`\`\`bash
+${shellQuote(path.join(SHARED_LIBS_ROOT, 'bin/gstack-review-log'))} --start review
+\`\`\`
+
+2. The trusted start-record location is ${startRecord}. Replace <REVIEW_START> with the token actually returned by --start. Read that token's record in a separate, successful Read tool call or a single cat command before continuing. Verify its repo, branch, working tree and start time. Do not combine the record read with --start, the diff or other diagnostic commands whose failure could invalidate the read; if the read fails, retry it before proceeding. Then read the diff in a subsequent call.
+
+3. Before checking reuse, directly read every supplied authored evidence path and the helper destination, including the changed worker even when its body appeared in the diff. Use native Read with explicit file paths, or cat/sed with literal path operands. These independent reads may be batched together, but their successful results must return before the checker. No path-variable loops, globs or process substitutions for these required reads. Other required inspections and structural fingerprinting can batch separately from receipt commands.
+
+4. The checker also reads and verifies that record without consuming it. Replace REVIEW_START below with that same literal token and CURRENT_FINDING_JSON with the current finding as literal JSON, retaining the quoted delimiter. Run this as the sole command in its Bash call from the target repo; stdout must be only one JSON value, with no preceding reads/fingerprinting or trailing output. Inspect reusable, review_start, fingerprint and snapshot.covered_paths before any later --finish invocation. This mechanical proof does not replace authored-source review. Use the supplied helper interfaces; discovering helper CLI options is outside this replay.
+
+\`\`\`bash
+${shellQuote(path.join(SHARED_LIBS_ROOT, 'bin/gstack-review-log'))} --check-shared-libs REVIEW_START <<'GSTACK_REVALIDATION_FINDING'
+CURRENT_FINDING_JSON
+GSTACK_REVALIDATION_FINDING
+\`\`\`
+
+5. Act on the checker result under the supplied finding's own evidence_paths/helper_target identity, exactly as the production shared-code-reuse rule requires:
+   - Suppress only when reusable:true AND your own reads independently confirm every supplied evidence path and the helper destination are unchanged, first-party authored source. Then the prior Skip carries forward. Ask no new decision question, exclude this advisory from the current pass's findings, and note it in the summary only as a suppressed prior decision. Do not re-persist it as a current finding or record a new disposition for it.
+   - Otherwise the prior decision does not carry forward. This covers reusable:false, a checker that failed or returned unreadable output, and reusable:true whose independent authored/current-source verification does not hold. Perform a fresh authored-source review and make an actual new decision for the current finding, preserving its evidence identity. Snapshot-ineligible supporting paths may be excluded from migration, savings and computed coverage; that does not silently remove them from the identity being revalidated. A materially revised proposal is a separate finding, never a replacement for the supplied finding's disposition. Do not make an unsupported proposal look worthwhile or mark it skipped without its actual explicit decision.
+   - An unsupported or unfinished supplied finding stays blocked and fails this replay regardless of the checker result; report it honestly and never force a new Skip on invalid evidence.
+
+6. Complete final evidence verification and assemble all record metadata in earlier calls. Replace FINAL_REVIEW_JSON below with the complete, shell-quoted literal record and REVIEW_START with the actual literal token. No preliminary commands, metadata substitutions or extra output in this final Bash call: combine successful --finish persistence and one complete, untruncated read-back through gstack-review-read in the same tool invocation exactly as below. Read back only after persistence succeeds, inspect the full current record and binding, then return the final review summary in conversation.
+
+\`\`\`bash
+${shellQuote(path.join(SHARED_LIBS_ROOT, 'bin/gstack-review-log'))} 'FINAL_REVIEW_JSON' --finish REVIEW_START && ${shellQuote(path.join(SHARED_LIBS_ROOT, 'bin/gstack-review-read'))}
+\`\`\`
+
 - Failed persistence or verification remains a failure. Late source changes still require the workflow's normal re-review; never skip checks, questions, or convergence rules to finish within the bound.`;

The referenced checklist is ${checklistPath}. Execute Step 9.3 and Step 9.4 through persistence, then obtain the unchanged rediscovery and apply the supplied Step 11 finish rules. This is not full /ship: earlier reviewers and the rediscovery are explicitly synthetic fixture inputs. No QA/probes/full review ran; persist completed:false and converged:false and never claim passing verification or release clearance. The native-completion bit refers only to the supplied synthetic result. Stop after selecting the next queue boundary; do not execute Step 11.5 or release work.
+
+Supported interactions, declared before launch:
+- Read only the four absolute files above, using file_path alone: no offset, limit, pages or other fields. After the rediscover command's result is acknowledged, issue a new full Read with exactly ${JSON.stringify({ file_path: product })}. Receive its actual tool result before issuing either routing command (advance or repeat), even when the result is file_unchanged and refers to the earlier full delivery. A Read before rediscovery or a prose claim of unchanged source does not satisfy this step.
+- One native AskUserQuestion with exactly this declared finding-disposition input: ${JSON.stringify(SHIP_SKIP_QUESTION)}. The owner chooses the no-change option. No other permission, combined request or risk-acceptance question is authorized.
+- Write only ${draft}, as the actual Step 9.4 JSON review record. Include the finding's fingerprint, severity, disposition and decision_evidence; preserve honest unresolved counts. Copy the canonical decision_evidence object from ${inputPath} unchanged, with exactly its path and sha256 fields and values; put any annotations outside decision_evidence. The adapter holds the original real REVIEW_START token, captured before source inspection. The record is outside the product checkout.
+- Bash accepts exactly these single commands, without chaining, redirection or backgrounding:
+  ${commands.read} invokes the real gstack-review-read in this fixture's owned state.
+  ${commands.persist} passes the written record to the real gstack-review-log with the original token.
+  ${commands.rediscover} returns the same completed synthetic Step 11 finding after the owner response and persistence, without changing source.
+  ${commands.advance} records selection of the Step 11.5 boundary and stops this fixture.
+  ${commands.repeat} records selection of another 9→10→11 review pass and stops this fixture.
+Use these bound adapters for the generated helper command examples. Choose the routing command from the workflow, not as a claim that shipping is cleared. The adapters do not decide which boundary you should select. Memory updates are outside this fixture. No product writes, direct receipt/config access, new start token, full reviewer dispatch, other commands, commits or publication are supported. Report the skipped defect and incomplete verification truthfully.`;
