* fix(gstack-slug): sanitize cached slug before eval

The compute and fallback paths filter slug output to [a-zA-Z0-9._-], but a
value read straight from ~/.gstack/slug-cache was echoed into eval output
unsanitized. A locally-planted cache file could inject shell into
eval "$(gstack-slug)". Re-sanitize on every path so the invariant the file
header promises actually holds, and heal a poisoned cache on the next write.

* fix(telemetry): accurate consent copy + JSON-safe repo basename

The telemetry consent prompt promised "no repo names" while the preamble
epilogue records the repo basename in the local skill-usage.jsonl. It is
already stripped before any remote upload, so it never left the machine, but
the copy was unqualified. Reword it to state repo name is local-only and
stripped before upload.

Also sanitize the basename to [a-zA-Z0-9._-] before it goes into the
hand-built JSON, so a repo directory name containing quotes or newlines can
neither break the JSON nor leak a fragment past the regex stripper.

fixtures refreshed to match.

* test(telemetry): enforce no-repo-identity-egress invariant

Pins the contract that repo/branch identity in the synced skill-usage.jsonl is
stripped before the remote POST. Three checks: a floor (the three known fields),
coverage (every repo/branch field a producer writes into skill-usage.jsonl is
stripped, so a future producer rename can't silently leak), and behavior (runs
the actual sed strip expressions over a sample event). Scoped to the synced
file, so the local-only timeline branch field is correctly excluded.

* test(gstack-slug): regression test for cached-slug eval injection

Proves a poisoned ~/.gstack/slug-cache file cannot inject shell metacharacters
into gstack-slug output (the value consumed by eval). Verified red when the
cache-read sanitization is removed.

 # Changelog
 
+## [1.55.1.0] - 2026-06-02
+
+## **Telemetry now tells you exactly what it records and where it stays. The project-slug helper hands the shell a safe identifier on every path.**
+
+The telemetry opt-in screen now states the truth without asterisks: it shares skill name, duration, crashes, and a stable device ID, with no code and no file paths, and your repo name is recorded locally only and stripped before any upload. Under the hood, the helper that every skill uses to find your project (`gstack-slug`) now filters its output to `[a-zA-Z0-9._-]` on every path, including the cached one, so the value that gets handed to the shell is always a plain identifier. Two regression tests lock both behaviors so they can't quietly drift back.
+
+### The guarantees that matter
+
+These are enforced by tests in this release, not promises (`bun test test/telemetry-repo-strip.test.ts test/gstack-slug-sanitize.test.ts`):
+
+| Guarantee | Pinned by |
+|-----------|-----------|
+| Your repo name never leaves the machine (stripped before upload) | `telemetry-repo-strip.test.ts` — floor + producer-coverage + runs the real strip over a sample event |
+| A tampered slug cache can't put shell characters into the helper's output | `gstack-slug-sanitize.test.ts` — fails if the sanitization is removed |
+| The consent copy matches what the code actually does | `generate-telemetry-prompt.ts` (regenerated into every skill) |
+
+The repo-identity test covers all three producer fields (`repo`, `_repo_slug`, `_branch`), so adding a new field that forgets to get stripped fails CI rather than shipping silently.
+
+### What this means for you
+
+Your telemetry choice screen now describes what actually happens, so you can opt in (or not) on accurate information. If you share a machine or have ever worried about a tampered `~/.gstack` cache, the slug helper now refuses to pass anything but a safe identifier to the shell. Nothing to do — both land automatically on upgrade.
+
+### Itemized changes
+
+#### Changed
+- Telemetry consent copy is now accurate: "No code or file paths. Your repo name is recorded locally only and stripped before any upload" (was "No code, file paths, or repo names").
+
+#### Fixed
+- `gstack-slug` sanitizes its output to `[a-zA-Z0-9._-]` on every path, including values read from its on-disk cache, so `eval "$(gstack-slug)"` always receives a plain identifier. A tampered cache file is also healed on the next write.
+- The telemetry preamble sanitizes the repo basename before building its JSON line, so an unusual repo directory name can't malform the local analytics record.
+
+#### Added
+- `test/telemetry-repo-strip.test.ts` — enforces that no repo/branch identity field reaches the upload batch (floor + producer-coverage + real-strip behavior).
+- `test/gstack-slug-sanitize.test.ts` — regression test proving a poisoned slug cache cannot inject shell metacharacters.
+
+#### For contributors
+- The consent copy and repo-basename handling live in `scripts/resolvers/preamble/`; all `SKILL.md` files and the ship goldens were regenerated from those resolvers.
+
+## [1.55.0.0] - 2026-05-30
+
+## **`/sync-gbrain` can no longer be the trigger that lets gbrain delete your repo. The headed browser stops crash-looping, and gbrain installs the current release instead of a pin 23 versions stale.**
+
+gbrain can rm-rf a working tree when its autopilot daemon reclones mid-cycle. `/sync-gbrain` used to call gbrain's `sources remove` and `sync --strategy code` as if they were safe, so it could be the thing that set that race off. Now every destructive gbrain call sits behind feature-detected guards: the orchestrator refuses to run while autopilot is active, refuses to remove a user-managed source it can't storage-protect (it fails closed), canonicalizes paths with realpath so a symlink can't smuggle a delete outside gbrain's own clones, and requires an explicit `--allow-reclone` before a URL-managed source's code walk. Shipped in the same wave: the headed browser's self-inflicted crash-loop is gone, big-brain memory ingests stop getting killed at a fixed 30 minutes, and the gbrain installer moves off its frozen v0.18.2 pin onto the latest release behind a version floor and a `doctor` self-test.
+
+### The numbers that matter
+
+From the shipped diff and its regression suites (`bun test test/gbrain-*.test.ts browse/test/restart-env.test.ts test/memory-ingest-timeout.test.ts`):
+
+| Metric | Before | After | Δ |
+|--------|--------|-------|---|
+| Destructive gbrain ops behind guards | 0 | 4 | +4 |
+| gbrain / brain-sync spawns that work on Windows | 0/8 | 8/8 | +8 |
+| gbrain version installed | v0.18.2 (pinned, ~23 behind) | latest + min-version floor + doctor gate | — |
+| Memory-ingest timeout | hardcoded 30 min | configurable, checkpoint preserved on timeout | — |
+| Generated SKILL.md that parse under strict YAML | partial (colons broke Codex) | all (quoted) | — |
+
+The guard that matters most: a `sources remove` on a source whose files live outside `~/.gbrain/clones/` and can't be storage-protected now refuses instead of proceeding. The path that ate a repo no longer runs unattended.
+
+### What this means for you
+
+If you use `/sync-gbrain`, you are protected from the data-loss race even before gbrain ships its own root fix. "Don't run `/sync-gbrain` while `gbrain autopilot` is active" is now enforced, not just advised, and nothing gets deleted that can't be proven safe. Headed-browser QA against beacon-heavy pages (analytics, live extensions) no longer crash-loops, leaks Chromium, or silently drops to an invisible headless window. New gbrain installs track the current release. Codex and OpenAI can load every gstack skill again.
+
+### Itemized changes
+
+#### Added
+- `/sync-gbrain` destructive-op guards (`lib/gbrain-guards.ts`): multi-signal autopilot detection, fail-closed `sources remove`, realpath `remote_url` pre-flight audit, and a `--allow-reclone` gate before URL-managed code walks.
+- Install-time gbrain gate (`bin/gstack-gbrain-install`): a minimum-version floor and a `gbrain doctor --fast` self-test, both hard-fail with remediation.
+- `GSTACK_INGEST_TIMEOUT_MS` to configure the memory-ingest timeout; on timeout the gbrain checkpoint is preserved so the next run resumes.
+
+#### Changed
+- gbrain installs at the latest default-branch HEAD by default; pin a commit with `gstack-gbrain-install --pinned-commit <sha>` for reproducibility.
+- Generated SKILL.md descriptions with interior colons are now quoted, so strict YAML loaders (Codex/OpenAI) parse them.
+- `/sync-gbrain` guidance: do not run during autopilot; prefer `gbrain sources add --path` over URL-managed sources.
+
+#### Fixed
+- `/sync-gbrain` no longer races gbrain's autopilot into a destructive reclone or remove (#1734). Report by @mvanhorn.
+- `gstack-jsonl-merge` resolves equal-timestamp entries deterministically across machines, so append-only logs converge instead of re-conflicting forever (#1769). Contributed by @jbetala7.
+- Generated SKILL.md frontmatter parses under strict YAML loaders (#1778). Reported by @GilbertzzzZZ, @genisis0x, @cathrynlavery, and @sator-imaging.
+- The headed browser daemon no longer crash-loops under load, leaks Chromium processes, or silently downgrades a headed session to headless (#1781).
+- `/sync-gbrain --full` memory ingests on large brains are no longer killed at a fixed 30-minute timeout (#1611).
+- The gbrain CLI and `gstack-brain-sync` spawn correctly on Windows (#1731).
+
+#### For contributors
+- `lib/gbrain-guards.ts` with hermetic tests for every guard branch (autopilot signals, fail-closed remove, reclone gate, realpath containment).
+- `parseSourcesList` centralizes `gbrain sources list --json` shape handling across all readers (#1576, whose crash was already fixed in v1.42.0.0 — this removes the last divergent reader).
+- Static-grep tripwire (`test/gbrain-spawn-windows-shell.test.ts`) fails CI if a gbrain spawn drops the Windows shell flag.
+- gbrain-side requirements for the root fixes (ungated reclone, `--keep-storage`, a cooperative remove-lease, a capability command, true ingest-resume, integration CI) are tracked for the gbrain repo.
+
+## [1.54.0.0] - 2026-05-30
+
+## **The heaviest skill stopped taxing every session. /ship's always-loaded cost dropped 59%, and its prose now loads only when a step needs it.**
+
+`/ship` was a 167KB wall that every session paid for in full, whether you were bumping a version or writing a changelog or none of it. It is now a 69KB decision-tree skeleton plus eight `sections/*.md` files the agent opens on demand. The eight steps that are long prose (the test run, coverage audit, plan-completion, the review army, Greptile triage, the adversarial pass, the changelog, the PR body) moved into sections behind STOP-Read pointers, so a run only reads the chapters its situation calls for. The version-bump logic that used to be ~90 lines of inline bash, the single worst re-bump footgun in the workflow, is now the tested `gstack-version-bump` CLI (classify / write / repair). Other hosts (codex, factory, kiro, opencode) keep the full inline skill unchanged, so nothing regresses off Claude. This release dogfooded itself: the version you are reading was bumped by `gstack-version-bump`.
+
+### The numbers that matter
+
+Measured directly from the generated skill (`wc -c ship/SKILL.md`) and the new section files, regenerated for all hosts:
+
+| Metric | Before (v1.53) | After (v1.54) | Δ |
+|--------|----------------|---------------|---|
+| ship always-loaded | 167 KB (~41.8K tokens) | 69 KB (~17.2K tokens) | -59% |
+| ship prose loaded per run | all of it | only applicable sections | on-demand |
+| ship version logic | ~90 lines inline bash | tested CLI, 15 unit tests | extracted |
+| External-host ship | 167 KB inline | 162 KB inline (unchanged behavior) | no regression |
+
+The skeleton is what loads the instant `/ship` is invoked, so the ~24.6K-token drop is paid back on every single ship, not just once.
+
+### What this means for you
+
+A `/ship` run starts ~3x lighter and pulls in each heavy step's instructions only when it reaches that step, so the agent spends less of its window holding prose it is not using yet. You will not notice any behavior change. The workflow is identical step for step; the difference is what is in context when. If you ever want to read a step in isolation, the chapters live at `~/.claude/skills/gstack/ship/sections/`.
+
+### Itemized changes
+
+#### Added
+- `bin/gstack-version-bump` — tested version-state CLI (classify / write / repair) with 15 unit tests covering the full FRESH / ALREADY_BUMPED / DRIFT_STALE_PKG / DRIFT_UNEXPECTED matrix.
+- `ship/sections/*.md` — eight on-demand sections (tests, test-coverage, plan-completion, review-army, greptile, adversarial, changelog, pr-body) with a passive `manifest.json` registry.
+- Section pipeline in `gen-skill-docs`: `{{SECTION:id}}` (STOP-Read pointer on Claude, inline on other hosts) and `{{SECTION_INDEX}}` (situation to section table rendered from the manifest).
+- `test/helpers/transcript-section-logger.ts` + `required-reads.ts` and section-loading / manifest-consistency / context-parity tests guarding the carve.
+
+#### Changed
+- `/ship` is a skeleton + sections on Claude; external hosts still receive the full inline skill (no behavior change off Claude).
+- Step 12 calls `gstack-version-bump` instead of inline bash.
+- Parity harness understands carved skills (checks skeleton + sections union; asserts the skeleton actually shrank).
+
+#### For contributors
+- `setup` links `sections/` into the prefixed Claude + Kiro skill dirs; `--host all` now fails the build on any host failure, not just claude.
+- New section templates live at `<skill>/sections/*.md.tmpl`; regenerate with `bun run gen:skill-docs`.
+## [1.53.1.0] - 2026-05-30
+
+## **Workspace and scripted setup never hang on a hidden prompt again. Installing the plan-tune hooks is now flag-driven with safe defaults.**
+
+`./setup` asked "Install both hooks now? [y/N]" with a blocking read. Run under a Conductor workspace or any forwarded terminal, that prompt had nobody to answer it, so setup hung forever. Now the decision comes from a flag, an env var, or saved config, and when nobody is there to answer it takes a safe default instead of waiting. A real terminal still gets the prompt, but it is time-bounded (auto-skips after 10s) so it can never stall a pipeline.
+
+### What this means for you
+
+- Spinning up a new workspace just works. `bin/dev-setup` runs fully non-interactively and never rewrites your global Claude settings behind your back.
+- Want the plan-tune hooks installed without a prompt? `./setup --plan-tune-hooks` (or `GSTACK_PLAN_TUNE_HOOKS=yes`, or `gstack-config set plan_tune_hooks yes`). Don't want them? `--no-plan-tune-hooks`. Leave it unset and a real terminal still asks once, then remembers.
+
+### Added
+
+- `--plan-tune-hooks` / `--no-plan-tune-hooks` / `--plan-tune-hooks=yes|no|prompt` flags on `./setup`, plus the `GSTACK_PLAN_TUNE_HOOKS` env var and a `plan_tune_hooks` config key (default `prompt`). Precedence: flag > env > saved config > prompt on a real terminal.
+
+### Fixed
+
+- `./setup` no longer hangs in non-interactive or forwarded-TTY contexts (Conductor workspaces, CI). The plan-tune consent prompt is time-bounded and defaults to skip.
+- `bin/dev-setup` runs setup non-interactively and can no longer silently rewrite your global `~/.claude/settings.json` to point at an ephemeral workspace path that breaks when the workspace is deleted.
+- Opt-in values like `YES`, `Yes`, or ` yes` are honored instead of being silently downgraded to skip, and `gstack-config` now rejects out-of-domain `plan_tune_hooks` values.
+
+### For contributors
+
+- New regression suite `test/setup-plan-tune-hooks-noninteractive.test.ts` (flag wiring, no-blocking-read guard, decision normalization, config round-trip + domain rejection, dev-setup pin) with host-config isolation via a temp `GSTACK_HOME`.
+- Rebaselined `test/parity-suite.test.ts` from the stale v1.44.1 anchor to v1.53.0.0. The 1.05 per-skill ratio is kept (only the anchor moved), absorbing legitimate v1.49–v1.53 planning-skill growth and clearing the 5 pre-existing parity failures noted in the v1.53.0.0 entry. Historical baselines retained for the v1→v2 audit trail.
+- De-flaked `test/plan-tune.test.ts` "derive pushes scope_appetite up" (was ~25–50% flaky, worse on main): it now sets `GSTACK_QUESTION_LOG_NO_DERIVE=1` so gstack-question-log's fire-and-forget background `--derive` can't race the test's explicit one.

Does NOT upgrade gbrain independently. gbrain installs at the latest HEAD by default; to refresh it, `git pull` in your gbrain clone (default `~/gbrain`) and re-run `/setup-gbrain`. Pin a specific commit with `gstack-gbrain-install --pinned-commit <sha>` if you need reproducibility. Installs below the minimum tested version are refused.
 - `/retro` — weekly retrospective pulls learnings and plans from your gbrain when memory sync is on, letting the retro reference cross-machine history.
 
 Run `/setup-gbrain` and see what sticks.

+/**
+ * gbrain-guards — defense-in-depth against gbrain's destructive code paths (#1734).
+ *
+ * gbrain (the separate CLI gstack shells out to) can rm-rf a user's working tree
+ * during an autopilot race (its own bug, upstream gbrain #1526). gstack can't fix
+ * that, but it MUST stop treating gbrain's destructive subcommands as safe. These
+ * guards gate the two ways the orchestrator can reach destruction:
+ *
+ *   1. `sources remove --confirm-destructive`  → decideSourceRemove()
+ *   2. `sync --strategy code` (can auto-reclone) → decideCodeSync()
+ *
+ * plus an autopilot-active check (detectAutopilot) that refuses to run destructive
+ * ops concurrently with the daemon.
+ *
+ * Design notes grounded in the real gbrain 0.41.x surface:
+ *   - There is NO `--keep-storage` flag and NO structured capability command, and
+ *     subcommand `--help` is generic — so capability detection is best-effort and
+ *     defaults to "unsupported". When we can't protect a user-managed source's
+ *     files, we FAIL CLOSED (refuse the remove) rather than delete unprotected.
+ *   - The autopilot lock filename isn't documented and (gbrain #1226) ignores
+ *     GBRAIN_HOME, so the live `gbrain autopilot` process is the PRIMARY signal;
+ *     known lock paths under both the configured home and ~/.gbrain are secondary.
+ *   - We refuse only on an AFFIRMATIVE autopilot signal — inability to introspect
+ *     never blocks a normal sync (that would brick the tool).
+ *   - Path containment uses realpath so a symlink inside ~/.gbrain/clones can't
+ *     smuggle a delete out to a user repo.
+ *
+ * Pure decision functions; the orchestrator logs the reasons (observability).

-npm run test 2>&1 | tee /tmp/ship_vitest.txt &

-```
-
-After both complete, read the output files and check pass/fail.
-
-**If any test fails:** Do NOT immediately stop. Apply the Test Failure Ownership Triage:
-
-{{TEST_FAILURE_TRIAGE}}
-
-**After triage:** If any in-branch failures remain unfixed, **STOP**. Do not proceed. If all failures were pre-existing and handled (fixed, TODOed, assigned, or skipped), continue to Step 6.
-
-**If all pass:** Continue silently — just note the counts briefly.
-
----
-
-## Step 6: Eval Suites (conditional)
-
-Evals are mandatory when prompt-related files change. Skip this step entirely if no prompt files are in the diff.
-
-**1. Check if the diff touches prompt-related files:**
-
-```bash
-git diff origin/<base> --name-only
-```
-
-Match against these patterns (from CLAUDE.md):
-- `app/services/*_prompt_builder.rb`
-- `app/services/*_generation_service.rb`, `*_writer_service.rb`, `*_designer_service.rb`
-- `app/services/*_evaluator.rb`, `*_scorer.rb`, `*_classifier_service.rb`, `*_analyzer.rb`
-- `app/services/concerns/*voice*.rb`, `*writing*.rb`, `*prompt*.rb`, `*token*.rb`
-- `app/services/chat_tools/*.rb`, `app/services/x_thread_tools/*.rb`
-- `config/system_prompts/*.txt`
-- `test/evals/**/*` (eval infrastructure changes affect all suites)
-
-**If no matches:** Print "No prompt-related files changed — skipping evals." and continue to Step 9.
-
-**2. Identify affected eval suites:**
-
-Each eval runner (`test/evals/*_eval_runner.rb`) declares `PROMPT_SOURCE_FILES` listing which source files affect it. Grep these to find which suites match the changed files:
-
-```bash
-grep -l "changed_file_basename" test/evals/*_eval_runner.rb
-```
-
-Map runner → test file: `post_generation_eval_runner.rb` → `post_generation_eval_test.rb`.
-
-**Special cases:**
-- Changes to `test/evals/judges/*.rb`, `test/evals/support/*.rb`, or `test/evals/fixtures/` affect ALL suites that use those judges/support files. Check imports in the eval test files to determine which.
-- Changes to `config/system_prompts/*.txt` — grep eval runners for the prompt filename to find affected suites.
-- If unsure which suites are affected, run ALL suites that could plausibly be impacted. Over-testing is better than missing a regression.
-
-**3. Run affected suites at `EVAL_JUDGE_TIER=full`:**
-
-`/ship` is a pre-merge gate, so always use full tier (Sonnet structural + Opus persona judges).
-
-```bash
-EVAL_JUDGE_TIER=full EVAL_VERBOSE=1 bin/test-lane --eval test/evals/<suite>_eval_test.rb 2>&1 | tee /tmp/ship_evals.txt
-```
-
-If multiple suites need to run, run them sequentially (each needs a test lane). If the first suite fails, stop immediately — don't burn API cost on remaining suites.
-
-**4. Check results:**
-
-- **If any eval fails:** Show the failures, the cost dashboard, and **STOP**. Do not proceed.
-- **If all pass:** Note pass counts and cost. Continue to Step 9.
-
-**5. Save eval output** — include eval results and cost dashboard in the PR body (Step 19).
-
-**Tier reference (for context — /ship always uses `full`):**
-| Tier | When | Speed (cached) | Cost |
-|------|------|----------------|------|
-| `fast` (Haiku) | Dev iteration, smoke tests | ~5s (14x faster) | ~$0.07/run |
-| `standard` (Sonnet) | Default dev, `bin/test-lane --eval` | ~17s (4x faster) | ~$0.37/run |
-| `full` (Opus persona) | **`/ship` and pre-merge** | ~72s (baseline) | ~$1.27/run |

-## Step 7: Test Coverage Audit
-
-**Dispatch this step as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent runs the coverage audit in a fresh context window — the parent only sees the conclusion, not intermediate file reads. This is context-rot defense.
-
-**Subagent prompt:** Pass the following instructions to the subagent, with `<base>` substituted with the base branch:
-
-> You are running a ship-workflow test coverage audit. Run `git diff <base>...HEAD` as needed. Do not commit or push — report only.
->
-> {{TEST_COVERAGE_AUDIT_SHIP}}
->
-> After your analysis, output a single JSON object on the LAST LINE of your response (no other text after it):
-> `{"coverage_pct":N,"gaps":N,"diagram":"<full markdown coverage diagram for PR body>","tests_added":["path",...]}`
-
-**Parent processing:**
-
-1. Read the subagent's final output. Parse the LAST line as JSON.
-2. Store `coverage_pct` (for Step 20 metrics), `gaps` (user summary), `tests_added` (for the commit).
-3. Embed `diagram` verbatim in the PR body's `## Test Coverage` section (Step 19).
-4. Print a one-line summary: `Coverage: {coverage_pct}%, {gaps} gaps. {tests_added.length} tests added.`
-
-**If the subagent fails, times out, or returns invalid JSON:** Fall back to running the audit inline in the parent. Do not block /ship on subagent failure — partial results are better than none.
-
----
-
-## Step 8: Plan Completion Audit
-
-**Dispatch this step as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent reads the plan file and every referenced code file in its own fresh context. Parent gets only the conclusion.
-
-**Subagent prompt:** Pass these instructions to the subagent:
-
-> You are running a ship-workflow plan completion audit. The base branch is `<base>`. Use `git diff <base>...HEAD` to see what shipped. Do not commit or push — report only.
->
-> {{PLAN_COMPLETION_AUDIT_SHIP}}
->
-> After your analysis, output a single JSON object on the LAST LINE of your response (no other text after it):
-> `{"total_items":N,"done":N,"changed":N,"deferred":N,"unverifiable":N,"summary":"<markdown checklist for PR body>"}`
-
-**Parent processing:**
-
-1. Parse the LAST line of the subagent's output as JSON.
-2. Store `done`, `deferred`, `unverifiable` for Step 20 metrics; use `summary` in PR body.
-3. If `deferred > 0` or `unverifiable > 0` and no user override, present the items via the appropriate AskUserQuestion (see Gate Logic priority order above) before continuing.
-4. Embed `summary` in PR body's `## Plan Completion` section (Step 19). If `unverifiable > 0` and the user picked option A in the UNVERIFIABLE gate, also embed `## Plan Completion — Manual Verifications` listing each user-confirmed item.
-
-**If the subagent fails or returns invalid JSON:** Fall back to running the audit inline (parent processes the same plan-extraction + classification logic). If the inline fallback also fails (e.g., plan file unreadable, parser error), do NOT silently pass — surface the failure as an explicit AskUserQuestion: "Plan Completion audit could not run ({reason}). Options: (A) Skip audit and ship anyway — record that the audit was skipped in PR body and Step 20 metrics; (B) Stop and fix the audit." Default and recommended option is (B). Silent fail-open is the failure shape that VAS-449 surfaced.

-## Step 9: Pre-Landing Review
-
-Review the diff for structural issues that tests don't catch.
-
-1. Read `.claude/skills/review/checklist.md`. If the file cannot be read, **STOP** and report the error.
-
-2. Run `git diff origin/<base>` to get the full diff (scoped to feature changes against the freshly-fetched base branch).
-
-3. Apply the review checklist in two passes:
-   - **Pass 1 (CRITICAL):** SQL & Data Safety, LLM Output Trust Boundary
-   - **Pass 2 (INFORMATIONAL):** All remaining categories
-
-{{CONFIDENCE_CALIBRATION}}
-
-{{DESIGN_REVIEW_LITE}}
-
-   Include any design findings alongside the code review findings. They follow the same Fix-First flow below.
-
-{{REVIEW_ARMY}}
-
-{{CROSS_REVIEW_DEDUP}}
-
-4. **Classify each finding from both the checklist pass and specialist review (Step 9.1-Step 9.2) as AUTO-FIX or ASK** per the Fix-First Heuristic in
-   checklist.md. Critical findings lean toward ASK; informational lean toward AUTO-FIX.
-
-5. **Auto-fix all AUTO-FIX items.** Apply each fix. Output one line per fix:
-   `[AUTO-FIXED] [file:line] Problem → what you did`
-
-6. **If ASK items remain,** present them in ONE AskUserQuestion:
-   - List each with number, severity, problem, recommended fix
-   - Per-item options: A) Fix  B) Skip
-   - Overall RECOMMENDATION
-   - If 3 or fewer ASK items, you may use individual AskUserQuestion calls instead
-
-7. **After all fixes (auto + user-approved):**
-   - If ANY fixes were applied: commit fixed files by name (`git add <fixed-files> && git commit -m "fix: pre-landing review fixes"`), then **STOP** and tell the user to run `/ship` again to re-test.
-   - If no fixes applied (all ASK items skipped, or no issues found): continue to Step 12.
-
-8. Output summary: `Pre-Landing Review: N issues — M auto-fixed, K asked (J fixed, L skipped)`
-
-   If no issues found: `Pre-Landing Review: No issues found.`
-
-9. Persist the review result to the review log:
-```bash
-~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"review","timestamp":"TIMESTAMP","status":"STATUS","issues_found":N,"critical":N,"informational":N,"quality_score":SCORE,"specialists":SPECIALISTS_JSON,"findings":FINDINGS_JSON,"commit":"'"$(git rev-parse --short HEAD)"'","via":"ship"}'
-```
-Substitute TIMESTAMP (ISO 8601), STATUS ("clean" if no issues, "issues_found" otherwise),
-and N values from the summary counts above. The `via:"ship"` distinguishes from standalone `/review` runs.
-- `quality_score` = the PR Quality Score computed in Step 9.2 (e.g., 7.5). If specialists were skipped (small diff), use `10.0`
-- `specialists` = the per-specialist stats object compiled in Step 9.2. Each specialist that was considered gets an entry: `{"dispatched":true/false,"findings":N,"critical":N,"informational":N}` if dispatched, or `{"dispatched":false,"reason":"scope|gated"}` if skipped. Example: `{"testing":{"dispatched":true,"findings":2,"critical":0,"informational":2},"security":{"dispatched":false,"reason":"scope"}}`
-- `findings` = array of per-finding records. For each finding (from checklist pass and specialists), include: `{"fingerprint":"path:line:category","severity":"CRITICAL|INFORMATIONAL","action":"ACTION"}`. ACTION is `"auto-fixed"`, `"fixed"` (user approved), or `"skipped"` (user chose Skip).
-
-Save the review output — it goes into the PR body in Step 19.
-
----
-
-## Step 10: Address Greptile review comments (if PR exists)
-
-**Dispatch the fetch + classification as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent pulls every Greptile comment, runs the escalation detection algorithm, and classifies each comment. Parent receives a structured list and handles user interaction + file edits.
-
-**Subagent prompt:**
-
-> You are classifying Greptile review comments for a /ship workflow. Read `.claude/skills/review/greptile-triage.md` and follow the fetch, filter, classify, and **escalation detection** steps. Do NOT fix code, do NOT reply to comments, do NOT commit — report only.
->
-> For each comment, assign: `classification` (`valid_actionable`, `already_fixed`, `false_positive`, `suppressed`), `escalation_tier` (1 or 2), the file:line or [top-level] tag, body summary, and permalink URL.
->
-> If no PR exists, `gh` fails, the API errors, or there are zero comments, output: `{"total":0,"comments":[]}` and stop.
->
-> Otherwise, output a single JSON object on the LAST LINE of your response:
-> `{"total":N,"comments":[{"classification":"...","escalation_tier":N,"ref":"file:line","summary":"...","permalink":"url"},...]}`
-
-**Parent processing:**
-
-Parse the LAST line as JSON.
-
-If `total` is 0, skip this step silently. Continue to Step 12.
-
-Otherwise, print: `+ {total} Greptile comments ({valid_actionable} valid, {already_fixed} already fixed, {false_positive} FP)`.
-
-For each comment in `comments`:
-
-**VALID & ACTIONABLE:** Use AskUserQuestion with:
-- The comment (file:line or [top-level] + body summary + permalink URL)
-- `RECOMMENDATION: Choose A because [one-line reason]`
-- Options: A) Fix now, B) Acknowledge and ship anyway, C) It's a false positive
-- If user chooses A: apply the fix, commit the fixed files (`git add <fixed-files> && git commit -m "fix: address Greptile review — <brief description>"`), reply using the **Fix reply template** from greptile-triage.md (include inline diff + explanation), and save to both per-project and global greptile-history (type: fix).
-- If user chooses C: reply using the **False Positive reply template** from greptile-triage.md (include evidence + suggested re-rank), save to both per-project and global greptile-history (type: fp).
-
-**VALID BUT ALREADY FIXED:** Reply using the **Already Fixed reply template** from greptile-triage.md — no AskUserQuestion needed:
-- Include what was done and the fixing commit SHA
-- Save to both per-project and global greptile-history (type: already-fixed)
-
-**FALSE POSITIVE:** Use AskUserQuestion:
-- Show the comment and why you think it's wrong (file:line or [top-level] + body summary + permalink URL)
-- Options:
-  - A) Reply to Greptile explaining the false positive (recommended if clearly wrong)
-  - B) Fix it anyway (if trivial)
-  - C) Ignore silently
-- If user chooses A: reply using the **False Positive reply template** from greptile-triage.md (include evidence + suggested re-rank), save to both per-project and global greptile-history (type: fp)
-
-**SUPPRESSED:** Skip silently — these are known false positives from previous triage.
-
-**After all comments are resolved:** If any fixes were applied, the tests from Step 5 are now stale. **Re-run tests** (Step 5) before continuing to Step 12. If no fixes were applied, continue to Step 12.

-### Refresh learnings for the headline feature on this branch
-
-The top-of-skill learnings pull was keyed to "release ship" broadly. Before the VERSION/CHANGELOG step, re-pull learnings keyed to THIS branch's headline feature so any prior version-bump or CHANGELOG pitfalls for similar features surface.
-
-Pick ONE keyword that names the headline feature you're shipping. The keyword should be a noun: the primary skill or module name, the central feature noun, or the binary you changed. The keyword MUST be alphanumeric or hyphen only — no quotes, slashes, dots, colons, or whitespace. If your candidate has any of those, simplify to just the alphanumeric stem.
-
-Worked examples (ship-specific): good keywords are `learnings-search`, `pacing`, `worktree-ship`. Bad: `the branch headline`, `v1.31.1.0`, `feat: token-or search`.

 ## Step 12: Version bump (auto-decide)
 
-**Idempotency check:** Before bumping, classify the state by comparing `VERSION` against the base branch AND against `package.json`'s `version` field. Four states: FRESH (do bump), ALREADY_BUMPED (skip bump), DRIFT_STALE_PKG (sync pkg only, no re-bump), DRIFT_UNEXPECTED (stop and ask).
+The deterministic version-state logic is the tested **`gstack-version-bump`** CLI
+(classify / write / repair). The bump-LEVEL decision and queue-collision handling
+stay agent judgment; the slot pick stays `gstack-next-version`.
 
+1. **Classify state** — pure reader, never writes:
    ```bash
-if ! git rev-parse --verify origin/<base> >/dev/null 2>&1; then
-  echo "ERROR: Unable to resolve origin/<base>. Run 'git fetch origin' or verify the base branch exists."
-  exit 1
-fi
-
-BASE_VERSION=$(git show origin/<base>:VERSION 2>/dev/null | tr -d '\r\n[:space:]' || echo "0.0.0.0")
-CURRENT_VERSION=$(cat VERSION 2>/dev/null | tr -d '\r\n[:space:]' || echo "0.0.0.0")
-[ -z "$BASE_VERSION" ] && BASE_VERSION="0.0.0.0"
-[ -z "$CURRENT_VERSION" ] && CURRENT_VERSION="0.0.0.0"
-PKG_VERSION=""
-PKG_EXISTS=0
-if [ -f package.json ]; then
-  PKG_EXISTS=1
-  if command -v node >/dev/null 2>&1; then
-    PKG_VERSION=$(node -e 'const p=require("./package.json");process.stdout.write(p.version||"")' 2>/dev/null)
-    PARSE_EXIT=$?
-  elif command -v bun >/dev/null 2>&1; then
-    PKG_VERSION=$(bun -e 'const p=require("./package.json");process.stdout.write(p.version||"")' 2>/dev/null)
-    PARSE_EXIT=$?

-    echo "ERROR: package.json exists but neither node nor bun is available. Install one and re-run."
-    exit 1

    ```
+   Read the JSON `state` and dispatch:
+   - **FRESH** → do the bump (steps 2-4).
+   - **ALREADY_BUMPED** → skip the bump, but run the queue-drift check (step 3) with the reported `currentVersion`. If the queue moved (next free version differs), **AskUserQuestion**: rebump to the new version (rewrites CHANGELOG header + PR title) or keep current (CI version-gate will reject until resolved).
+   - **DRIFT_STALE_PKG** → run `gstack-version-bump repair` (syncs package.json to VERSION). No re-bump; reuse `currentVersion` for CHANGELOG + PR.
+   - **DRIFT_UNEXPECTED** → **STOP**. package.json disagrees with VERSION while VERSION matches base — a manual edit bypassed /ship. Reconcile manually, then re-run.
 
-Read the `STATE:` line and dispatch:
-
-- **FRESH** → proceed with the bump action below (steps 1–4).
-- **ALREADY_BUMPED** → skip the bump by default, BUT check for queue drift first: call `bin/gstack-next-version` with the implied bump level (derived from `CURRENT_VERSION` vs `BASE_VERSION`), compare its `.version` against `CURRENT_VERSION`. If they differ (queue moved since last ship), use **AskUserQuestion**: "VERSION drift detected: you claim v<CURRENT> but next available is v<NEW> (queue moved). A) Rebump to v<NEW> and rewrite CHANGELOG header + PR title (recommended), B) Keep v<CURRENT> — will be rejected by CI version-gate until resolved." If A, treat this as FRESH with `NEW_VERSION=<new>` and run steps 1-4 (which will also trigger Step 13 CHANGELOG header rewrite and Step 19 PR title rewrite). If B, reuse `CURRENT_VERSION` and warn that CI will likely reject. If util is offline, warn and reuse `CURRENT_VERSION`.
-- **DRIFT_STALE_PKG** → a prior `/ship` bumped `VERSION` but failed to update `package.json`. Run the sync-only repair block below (after step 4). Do NOT re-bump. Reuse `CURRENT_VERSION` for CHANGELOG and PR body. (Queue check still runs in ALREADY_BUMPED terms after repair.)
-- **DRIFT_UNEXPECTED** → `/ship` has halted (exit 1). Resolve manually; /ship cannot tell which file is authoritative.
-
-1. Read the current `VERSION` file (4-digit format: `MAJOR.MINOR.PATCH.MICRO`)
-
-2. **Auto-decide the bump level based on the diff:**
-   - Count lines changed (`git diff origin/<base>...HEAD --stat | tail -1`)
-   - Check for feature signals: new route/page files (e.g. `app/*/page.tsx`, `pages/*.ts`), new DB migration/schema files, new test files alongside new source files, or branch name starting with `feat/`
-   - **MICRO** (4th digit): < 50 lines changed, trivial tweaks, typos, config
-   - **PATCH** (3rd digit): 50+ lines changed, no feature signals detected
-   - **MINOR** (2nd digit): **ASK the user** if ANY feature signal is detected, OR 500+ lines changed, OR new modules/packages added
-   - **MAJOR** (1st digit): **ASK the user** — only for milestones or breaking changes
-
-   Save the chosen level as `BUMP_LEVEL` (one of `major`, `minor`, `patch`, `micro`). This is the user-intended level. The next step decides *placement* — the level stays the same even if queue-aware allocation has to advance past a claimed slot.
-
-3. **Queue-aware version pick (workspace-aware ship, v1.6.4.0+).** Call `bin/gstack-next-version` to see what's already claimed by open PRs + active sibling Conductor worktrees, then render the queue state to the user:
+2. **Decide the bump level** from the diff (agent judgment):
+   - **MICRO**: <50 lines, trivial tweaks/config. **PATCH**: 50+ lines, no feature signals.
+   - **MINOR**: **ASK** if any feature signal (new route/page, migration, new module), OR 500+ lines. **MAJOR**: **ASK** — milestones or breaking changes only.
+   Save as `BUMP_LEVEL`. The level is the user-intended bump; queue-aware placement may advance the slot without changing the level.
 
+3. **Queue-aware pick** (workspace-aware ship):
    ```bash
-   QUEUE_JSON=$(bun run bin/gstack-next-version \
-     --base <base> \
-     --bump "$BUMP_LEVEL" \
-     --current-version "$BASE_VERSION" 2>/dev/null || echo '{"offline":true}')
+   QUEUE_JSON=$(bun run ~/.claude/skills/gstack/bin/gstack-next-version --base <base> --bump "$BUMP_LEVEL" --current-version "$BASE_VERSION" 2>/dev/null || echo '{"offline":true}')
    NEW_VERSION=$(echo "$QUEUE_JSON" | jq -r '.version // empty')
-   CLAIMED_COUNT=$(echo "$QUEUE_JSON" | jq -r '.claimed | length')
-   ACTIVE_SIBLING_COUNT=$(echo "$QUEUE_JSON" | jq -r '.active_siblings | length')
-   OFFLINE=$(echo "$QUEUE_JSON" | jq -r '.offline // false')
-   REASON=$(echo "$QUEUE_JSON" | jq -r '.reason // ""')
    ```
+   If `offline`/util fails: fall back to local `BUMP_LEVEL` arithmetic and print `⚠ workspace-aware ship offline — using local bump only`. If `claimed` is non-empty, render the queue table so the user sees landing order. If an active sibling workspace holds a version `>= NEW_VERSION`, **AskUserQuestion**: advance past (unrelated work) or abort and sync with the sibling.
 
-   - If `OFFLINE=true` or the util fails (auth expired, no `gh`/`glab`, network): fall back to local `BUMP_LEVEL` arithmetic (bump `BASE_VERSION` at the chosen level). Print `⚠ workspace-aware ship offline — using local bump only`. Continue.
-   - If `CLAIMED_COUNT > 0`: render the queue table to the user so they can see landing order at a glance:
-     ```
-     Queue on <base> (vBASE_VERSION):
-       #<pr> <branch> → v<version>   [⚠ collision with #<other>]
-     Active sibling workspaces (WIP, not yet PR'd):
-       <path> → v<version> (committed Nh ago)
-     Your branch will claim: vNEW_VERSION  (<reason>)
-     ```
-   - If `ACTIVE_SIBLING_COUNT > 0` and any active sibling's VERSION is `>= NEW_VERSION`, use **AskUserQuestion**: "Sibling workspace <path> has v<X> committed <N>h ago but hasn't PR'd yet. Wait for them to ship first, or advance past? A) Advance past (recommended for unrelated work), B) Abort /ship and sync up with sibling first."
-   - Validate `NEW_VERSION` matches `MAJOR.MINOR.PATCH.MICRO`. If util returns an empty or malformed version, fall back to local bump.
-
-4. **Validate** `NEW_VERSION` and write it to **both** `VERSION` and `package.json`. This block runs only when `STATE: FRESH`.
-
+4. **Write the bump** (FRESH, or an approved rebump):
    ```bash
-if ! printf '%s' "$NEW_VERSION" | grep -qE '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$'; then
-  echo "ERROR: NEW_VERSION ($NEW_VERSION) does not match MAJOR.MINOR.PATCH.MICRO pattern. Aborting."

-if [ -f package.json ]; then

-      echo "ERROR: failed to update package.json. VERSION was written but package.json is now stale. Fix and re-run — the new idempotency check will detect the drift."
-      exit 1

-  elif command -v bun >/dev/null 2>&1; then

-fi
+   bun run ~/.claude/skills/gstack/bin/gstack-version-bump write --version "$NEW_VERSION"
    ```
+   The CLI validates the 4-digit `MAJOR.MINOR.PATCH.MICRO` pattern and writes **both** VERSION and package.json. On a half-write (VERSION written, package.json failed) it exits 3 — re-run, and classify will report DRIFT_STALE_PKG for `repair` to fix.
 
-**DRIFT_STALE_PKG repair path** — runs when idempotency reports `STATE: DRIFT_STALE_PKG`. No re-bump; sync `package.json.version` to the current `VERSION` and continue. Reuse `CURRENT_VERSION` for CHANGELOG and PR body.
-
-```bash
-REPAIR_VERSION=$(cat VERSION | tr -d '\r\n[:space:]')
-if ! printf '%s' "$REPAIR_VERSION" | grep -qE '^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+$'; then
-  echo "ERROR: VERSION file contents ($REPAIR_VERSION) do not match MAJOR.MINOR.PATCH.MICRO pattern. Refusing to propagate invalid semver into package.json. Fix VERSION manually, then re-run /ship."
-  exit 1

-## Step 18: Documentation sync (via subagent, before PR creation)
-
-**Dispatch /document-release as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent gets a fresh context window — zero rot from the preceding 17 steps. It also runs the **full** `/document-release` workflow (with CHANGELOG clobber protection, doc exclusions, risky-change gates, named staging, race-safe PR body editing) rather than a weaker reimplementation.
-
-**Sequencing:** This step runs AFTER Step 17 (Push) and BEFORE Step 19 (Create PR). The PR is created once from final HEAD with the `## Documentation` section baked into the initial body. No create-then-re-edit dance.
-
-**Subagent prompt:**
-
-> You are executing the /document-release workflow after a code push. Read the full skill file `${HOME}/.claude/skills/gstack/document-release/SKILL.md` and execute its complete workflow end-to-end, including CHANGELOG clobber protection, doc exclusions, risky-change gates, and named staging. Do NOT attempt to edit the PR body — no PR exists yet. Branch: `<branch>`, base: `<base>`.
->
-> After completing the workflow, output a single JSON object on the LAST LINE of your response (no other text after it):
-> `{"files_updated":["README.md","CLAUDE.md",...],"commit_sha":"abc1234","pushed":true,"documentation_section":"<markdown block for PR body's ## Documentation section>"}`
->
-> If no documentation files needed updating, output:
-> `{"files_updated":[],"commit_sha":null,"pushed":false,"documentation_section":null}`
-
-**Parent processing:**
-
-1. Parse the LAST line of the subagent's output as JSON.
-2. Store `documentation_section` — Step 19 embeds it in the PR body (or omits the section if null).
-3. If `files_updated` is non-empty, print: `Documentation synced: {files_updated.length} files updated, committed as {commit_sha}`.
-4. If `files_updated` is empty, print: `Documentation is current — no updates needed.`
-
-**If the subagent fails or returns invalid JSON:** Print a warning and proceed to Step 19 without a `## Documentation` section. Do not block /ship on subagent failure. The user can run `/document-release` manually after the PR lands.

-
-## Step 19: Create PR/MR
-
-**Idempotency check:** Check if a PR/MR already exists for this branch.
-
-**If GitHub:**
-```bash
-gh pr view --json url,number,state -q 'if .state == "OPEN" then "PR #\(.number): \(.url)" else "NO_PR" end' 2>/dev/null || echo "NO_PR"
-```
-
-**If GitLab:**
-```bash
-glab mr view -F json 2>/dev/null | jq -r 'if .state == "opened" then "MR_EXISTS" else "NO_MR" end' 2>/dev/null || echo "NO_MR"
-```
-
-If an **open** PR/MR already exists: **update** the PR body using `gh pr edit --body-file "$PR_BODY_FILE"` (GitHub) or `glab mr update -d ...` (GitLab). Always regenerate the PR body from scratch using this run's fresh results (test output, coverage audit, review findings, adversarial review, TODOS summary, documentation_section from Step 18). Never reuse stale PR body content from a prior run. **Run the same redaction scan-at-sink (PR body + title) as the create path (Step 19) before editing — scan the temp file, then `gh pr edit --body-file` from it.**
-
-**Always update the PR title to start with `v$NEW_VERSION`.** PR titles use the workspace-aware format `v<NEW_VERSION> <type>: <summary>` — version ALWAYS first, no exceptions, no "custom title kept intentionally" escape hatch. The shared helper `bin/gstack-pr-title-rewrite.sh` is the single source of truth for the rule.
-
-1. Read the current title: `CURRENT=$(gh pr view --json title -q .title)` (or `glab mr view -F json | jq -r .title`).
-2. Compute the corrected title: `NEW_TITLE=$(~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh "$NEW_VERSION" "$CURRENT")`. The helper handles three cases: title already correct (no-op), title has a different `v<X.Y.Z.W>` prefix (replace it), or title has no version prefix (prepend one).
-3. If `NEW_TITLE` differs from `CURRENT`, run `gh pr edit --title "$NEW_TITLE"` (or `glab mr update -t "$NEW_TITLE"`).
-4. **Self-check:** re-fetch the title and assert it starts with `v$NEW_VERSION `. If it does not, retry the edit once. If still wrong, surface the failure to the user.
-
-This keeps the title truthful when Step 12's queue-drift detection rebumps a stale version, and forces the format on PRs that were created without it.
-
-Print the existing URL and continue to Step 20.
-
-If no PR/MR exists: create a pull request (GitHub) or merge request (GitLab) using the platform detected in Step 0.
-
-The PR/MR body should contain these sections:
-
-```

+
+### Claude adversarial subagent (always runs)
+
+Dispatch via the Agent tool. The subagent has fresh context — no checklist bias from the structured review. This genuine independence catches things the primary reviewer is blind to.
+
+Subagent prompt:
+"Read the diff for this branch with `DIFF_BASE=$(git merge-base origin/<base> HEAD) && git diff "$DIFF_BASE"`. Think like an attacker and a chaos engineer. Your job is to find ways this code will fail in production. Look for: edge cases, race conditions, security holes, resource leaks, failure modes, silent data corruption, logic errors that produce wrong results silently, error handling that swallows failures, and trust boundary violations. Be adversarial. Be thorough. No compliments — just the problems. For each finding, classify as FIXABLE (you know how to fix it) or INVESTIGATE (needs human judgment). After listing findings, end your output with ONE line in the canonical format `Recommendation: <action> because <one-line reason naming the most exploitable finding>` — examples: `Recommendation: Fix the unbounded retry at queue.ts:78 because it'll DoS the worker pool under sustained 429s` or `Recommendation: Ship as-is because the strongest finding is a theoretical race that requires conditions we can't trigger in production`. The reason must point to a specific finding (or no-fix rationale). Generic reasons like 'because it's safer' do not qualify."
+
+Present findings under an `ADVERSARIAL REVIEW (Claude subagent):` header. **FIXABLE findings** flow into the same Fix-First pipeline as the structured review. **INVESTIGATE findings** are presented as informational.
+
+If the subagent fails or times out: "Claude adversarial subagent unavailable. Continuing."
+
+---
+
+### Codex adversarial challenge (always runs when available)
+
+If Codex is available AND `OLD_CFG` is NOT `disabled`:
+
+```bash
+TMPERR_ADV=$(mktemp /tmp/codex-adv-XXXXXXXX)
+_REPO_ROOT=$(git rev-parse --show-toplevel) || { echo "ERROR: not in a git repo" >&2; exit 1; }
+codex exec "IMPORTANT: Do NOT read or execute any files under ~/.claude/, ~/.agents/, .claude/skills/, or agents/. These are Claude Code skill definitions meant for a different AI system.

Stay focused on the repository code only.\n\nReview the changes on this branch against the base branch. Run DIFF_BASE=$(git merge-base origin/<base> HEAD) && git diff "$DIFF_BASE" to see the diff.

+```
+
+Set the Bash tool's `timeout` parameter to `300000` (5 minutes). Do NOT use the `timeout` shell command — it doesn't exist on macOS. After the command completes, read stderr:
+```bash
+cat "$TMPERR_ADV"
+```
+
+Present the full output verbatim. This is informational — it never blocks shipping.
+
+**Error handling:** All errors are non-blocking — adversarial review is a quality enhancement, not a prerequisite.
+- **Auth failure:** If stderr contains "auth", "login", "unauthorized", or "API key": "Codex authentication failed. Run \`codex login\` to authenticate."
+- **Timeout:** "Codex timed out after 5 minutes."
+- **Empty response:** "Codex returned no response. Stderr: <paste relevant error>."
+
+**Cleanup:** Run `rm -f "$TMPERR_ADV"` after processing.
+
+If Codex is NOT available: "Codex CLI not found — running Claude adversarial only. Install Codex for cross-model coverage: `npm install -g @openai/codex`"
+
+---
+
+### Codex structured review (large diffs only, 200+ lines)
+
+If `DIFF_TOTAL >= 200` AND Codex is available AND `OLD_CFG` is NOT `disabled`:
+
+```bash
+TMPERR=$(mktemp /tmp/codex-review-XXXXXXXX)
+_REPO_ROOT=$(git rev-parse --show-toplevel) || { echo "ERROR: not in a git repo" >&2; exit 1; }
+cd "$_REPO_ROOT"
+codex review "IMPORTANT: Do NOT read or execute any files under ~/.claude/, ~/.agents/, .claude/skills/, or agents/. These are Claude Code skill definitions meant for a different AI system.

Stay focused on the repository code only.\n\nReview the changes on this branch against the base branch <base>. Run git diff origin/<base>...HEAD 2>/dev/null || git diff <base>...HEAD to see the diff and review only those changes." -c 'model_reasoning_effort="high"' --enable web_search_cached < /dev/null 2>"$TMPERR"
+```
+
+Set the Bash tool's `timeout` parameter to `300000` (5 minutes). Do NOT use the `timeout` shell command — it doesn't exist on macOS. Present output under `CODEX SAYS (code review):` header.
+Check for `[P1]` markers: found → `GATE: FAIL`, not found → `GATE: PASS`.
+
+If GATE is FAIL, use AskUserQuestion:
+```
+Codex found N critical issues in the diff.
+
+A) Investigate and fix now (recommended)
+B) Continue — review will still complete
+```
+
+If A: address the findings. After fixing, re-run tests (Step 5) since code has changed. Re-run `codex review` to verify.
+
+Read stderr for errors (same error handling as Codex adversarial above).
+
+After stderr: `rm -f "$TMPERR"`
+
+If `DIFF_TOTAL < 200`: skip this section silently. The Claude + Codex adversarial passes provide sufficient coverage for smaller diffs.
+
+---
+
+### Persist the review result
+
+After all passes complete, persist:
+```bash
+~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"adversarial-review","timestamp":"'"$(date -u +%Y-%m-%dT%H:%M:%SZ)"'","status":"STATUS","source":"SOURCE","tier":"always","gate":"GATE","commit":"'"$(git rev-parse --short HEAD)"'"}'
+```
+Substitute: STATUS = "clean" if no findings across ALL passes, "issues_found" if any pass found issues. SOURCE = "both" if Codex ran, "claude" if only Claude subagent ran. GATE = the Codex structured review gate result ("pass"/"fail"), "skipped" if diff < 200, or "informational" if Codex was unavailable. If all passes failed, do NOT persist.
+
+---
+
+### Cross-model synthesis
+
+After all passes complete, synthesize findings across all sources:
+
+```
+ADVERSARIAL REVIEW SYNTHESIS (always-on, N lines):
+════════════════════════════════════════════════════════════
+  High confidence (found by multiple sources): [findings agreed on by >1 pass]
+  Unique to Claude structured review: [from earlier step]
+  Unique to Claude adversarial: [from subagent]
+  Unique to Codex: [from codex adversarial or code review, if ran]
+  Models used: Claude structured ✓  Claude adversarial ✓/✗  Codex ✓/✗
+════════════════════════════════════════════════════════════
+```
+
+High-confidence findings (agreed on by multiple sources) should be prioritized for fixes.
+
+---
+
+## Capture Learnings
+
+If you discovered a non-obvious pattern, pitfall, or architectural insight during
+this session, log it for future sessions:
+
+```bash
+~/.claude/skills/gstack/bin/gstack-learnings-log '{"skill":"ship","type":"TYPE","key":"SHORT_KEY","insight":"DESCRIPTION","confidence":N,"source":"SOURCE","files":["path/to/relevant/file"]}'
+```
+
+**Types:** `pattern` (reusable approach), `pitfall` (what NOT to do), `preference`
+(user stated), `architecture` (structural decision), `tool` (library/framework insight),
+`operational` (project environment/CLI/workflow knowledge).
+
+**Sources:** `observed` (you found this in the code), `user-stated` (user told you),
+`inferred` (AI deduction), `cross-model` (both Claude and Codex agree).
+
+**Confidence:** 1-10. Be honest. An observed pattern you verified in the code is 8-9.
+An inference you're not sure about is 4-5. A user preference they explicitly stated is 10.
+
+**files:** Include the specific file paths this learning references. This enables
+staleness detection: if those files are later deleted, the learning can be flagged.
+
+**Only log genuine discoveries.** Don't log obvious things. Don't log things the user
+already knows. A good test: would this insight save time in a future session? If yes, log it.
+
+
+
+### Refresh learnings for the headline feature on this branch
+
+The top-of-skill learnings pull was keyed to "release ship" broadly. Before the VERSION/CHANGELOG step, re-pull learnings keyed to THIS branch's headline feature so any prior version-bump or CHANGELOG pitfalls for similar features surface.
+
+Pick ONE keyword that names the headline feature you're shipping. The keyword should be a noun: the primary skill or module name, the central feature noun, or the binary you changed. The keyword MUST be alphanumeric or hyphen only — no quotes, slashes, dots, colons, or whitespace. If your candidate has any of those, simplify to just the alphanumeric stem.
+
+Worked examples (ship-specific): good keywords are `learnings-search`, `pacing`, `worktree-ship`. Bad: `the branch headline`, `v1.31.1.0`, `feat: token-or search`.
+
+```bash
+~/.claude/skills/gstack/bin/gstack-learnings-search --query "<your-keyword>" --limit 5 2>/dev/null || true
+```
+
+If any learnings come back, name which one applies to the version bump or CHANGELOG framing in one sentence. If none come back, continue without reference — the absence is itself useful information.

+## Step 13: CHANGELOG (auto-generate)
+
+1. Read `CHANGELOG.md` header to know the format.
+
+2. **First, enumerate every commit on the branch:**
+   ```bash
+   git log <base>..HEAD --oneline
+   ```
+   Copy the full list. Count the commits. You will use this as a checklist.
+
+3. **Read the full diff** to understand what each commit actually changed:
+   ```bash
+   git diff <base>...HEAD
+   ```
+
+4. **Group commits by theme** before writing anything. Common themes:
+   - New features / capabilities
+   - Performance improvements
+   - Bug fixes
+   - Dead code removal / cleanup
+   - Infrastructure / tooling / tests
+   - Refactoring
+
+5. **Write the CHANGELOG entry** covering ALL groups:
+   - If existing CHANGELOG entries on the branch already cover some commits, replace them with one unified entry for the new version
+   - Categorize changes into applicable sections:
+     - `### Added` — new features
+     - `### Changed` — changes to existing functionality
+     - `### Fixed` — bug fixes
+     - `### Removed` — removed features
+   - Write concise, descriptive bullet points
+   - Insert after the file header (line 5), dated today
+   - Format: `## [X.Y.Z.W] - YYYY-MM-DD`
+   - **Voice:** Lead with what the user can now **do** that they couldn't before. Use plain language, not implementation details. Never mention TODOS.md, internal tracking, or contributor-facing details.
+
+6. **Cross-check:** Compare your CHANGELOG entry against the commit list from step 2.
+   Every commit must map to at least one bullet point. If any commit is unrepresented,
+   add it now. If the branch has N commits spanning K themes, the CHANGELOG must
+   reflect all K themes.
+
+**Do NOT ask the user to describe changes.** Infer from the diff and commit history.

+- If user chooses C: reply using the **False Positive reply template** from greptile-triage.md (include evidence + suggested re-rank), save to both per-project and global greptile-history (type: fp).
+

+## Step 8: Plan Completion Audit
+
+**Dispatch this step as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent reads the plan file and every referenced code file in its own fresh context. Parent gets only the conclusion.
+
+**Subagent prompt:** Pass these instructions to the subagent:
+
+> You are running a ship-workflow plan completion audit. The base branch is `<base>`. Use `git diff <base>...HEAD` to see what shipped. Do not commit or push — report only.
+>
+> ### Plan File Discovery
+
+1. **Conversation context (primary):** Check if there is an active plan file in this conversation. The host agent's system messages include plan file paths when in plan mode. If found, use it directly — this is the most reliable signal.
+
+2. **Content-based search (fallback):** If no plan file is referenced in conversation context, search by content:
+
+```bash
+setopt +o nomatch 2>/dev/null || true  # zsh compat
+BRANCH=$(git branch --show-current 2>/dev/null | tr '/' '-')
+REPO=$(basename "$(git rev-parse --show-toplevel 2>/dev/null)")
+# Compute project slug for ~/.gstack/projects/ lookup
+_PLAN_SLUG=$(git remote get-url origin 2>/dev/null | sed 's|.*[:/]\([^/]*/[^/]*\)\.git$|\1|;s|.*[:/]\([^/]*/[^/]*\)$|\1|' | tr '/' '-' | tr -cd 'a-zA-Z0-9._-') || true
+_PLAN_SLUG="${_PLAN_SLUG:-$(basename "$PWD" | tr -cd 'a-zA-Z0-9._-')}"
+# Search common plan file locations (project designs first, then personal/local)
+for PLAN_DIR in "$HOME/.gstack/projects/$_PLAN_SLUG" "$HOME/.claude/plans" "$HOME/.codex/plans" ".gstack/plans"; do
+  [ -d "$PLAN_DIR" ] || continue
+  PLAN=$(ls -t "$PLAN_DIR"/*.md 2>/dev/null | xargs grep -l "$BRANCH" 2>/dev/null | head -1)
+  [ -z "$PLAN" ] && PLAN=$(ls -t "$PLAN_DIR"/*.md 2>/dev/null | xargs grep -l "$REPO" 2>/dev/null | head -1)
+  [ -z "$PLAN" ] && PLAN=$(find "$PLAN_DIR" -name '*.md' -mmin -1440 -maxdepth 1 2>/dev/null | xargs ls -t 2>/dev/null | head -1)
+  [ -n "$PLAN" ] && break
+done
+[ -n "$PLAN" ] && echo "PLAN_FILE: $PLAN" || echo "NO_PLAN_FILE"
+```
+
+3. **Validation:** If a plan file was found via content-based search (not conversation context), read the first 20 lines and verify it is relevant to the current branch's work. If it appears to be from a different project or feature, treat as "no plan file found."
+
+**Error handling:**
+- No plan file found → skip with "No plan file detected — skipping."
+- Plan file found but unreadable (permissions, encoding) → skip with "Plan file found but unreadable — skipping."
+
+### Actionable Item Extraction
+
+Read the plan file. Extract every actionable item — anything that describes work to be done. Look for:
+
+- **Checkbox items:** `- [ ] ...` or `- [x] ...`
+- **Numbered steps** under implementation headings: "1. Create ...", "2. Add ...", "3. Modify ..."
+- **Imperative statements:** "Add X to Y", "Create a Z service", "Modify the W controller"
+- **File-level specifications:** "New file: path/to/file.ts", "Modify path/to/existing.rb"

+- Explicitly deferred items ("Future:", "Out of scope:", "NOT in scope:", "P2:", "P3:", "P4:")
+- CEO Review Decisions sections (these record choices, not work items)
+
+**Cap:** Extract at most 50 items. If the plan has more, note: "Showing top 50 of N plan items — full list in plan file."
+
+**No items found:** If the plan contains no extractable actionable items, skip with: "Plan file contains no actionable items — skipping completion audit."
+
+For each item, note:
+- The item text (verbatim or concise summary)
+- Its category: CODE | TEST | MIGRATION | CONFIG | DOCS
+
+### Verification Mode
+
+Before judging completion, classify HOW each item can be verified. The diff alone cannot prove every kind of work. Items outside the current repo or system are structurally invisible to `git diff`.
+
+- **DIFF-VERIFIABLE** — A code change in this repo would manifest in `git diff <base>...HEAD`. Examples: "add UserService" (file appears), "validate input X" (validation logic appears), "create users table" (migration file appears).
+- **CROSS-REPO** — Item names a file or change in a sibling repo (e.g., `domain-hq/docs/dashboard.md`, `~/Development/<other-repo>/...`). The current diff CANNOT prove this.
+- **EXTERNAL-STATE** — Item names state in an external system: Supabase config/RLS, Cloudflare DNS, Vercel env vars, OAuth provider allowlists, third-party SaaS, DNS records. The current diff CANNOT prove this.
+- **CONTENT-SHAPE** — Item requires a file to follow a specific convention. If the file is in this repo: diff-verifiable. If in another repo or system: see CROSS-REPO / EXTERNAL-STATE.
+
+**Verification dispatch:**
+
+- **DIFF-VERIFIABLE** → cross-reference against diff (next section).
+- **CROSS-REPO** → if the sibling repo is reachable on disk (try `~/Development/<repo>/`, `~/code/<repo>/`, the parent of the current repo), run `[ -f <path> ]` to check file existence. File exists → DONE (cite path). File missing → NOT DONE (cite path). Path unreachable → UNVERIFIABLE (cite what needs manual check).
+- **EXTERNAL-STATE** → UNVERIFIABLE. Cite the system and the specific check the user must perform.
+- **CONTENT-SHAPE in another repo** → if the file exists, run any project-detected validator (see "Validator detection" below) before falling back to UNVERIFIABLE. With a validator: pass → DONE; fail → NOT DONE (cite validator output). No validator available: classify UNVERIFIABLE and cite both the file path and the convention to confirm.
+
+**Path concreteness rule.** If a plan item names a *concrete filesystem path* (absolute, `~/...`, or `<sibling-repo>/<file>`), it MUST be classified DONE or NOT DONE based on `[ -f <path> ]`. UNVERIFIABLE is only valid when the path is genuinely abstract ("Cloudflare DNS", "Supabase allowlist") or the sibling root is unreachable on this machine. "I don't want to check" is not unreachable.
+
+**Validator detection.** Before falling back to UNVERIFIABLE on a CONTENT-SHAPE item, scan the target repo's `package.json` for any script matching `validate-*`, `lint-wiki`, `check-docs`, or similar. If found, invoke it with the relevant path argument (e.g., `npm run validate-wiki -- <path>`). For multi-target validators (e.g., `validate-wiki --all`), run once and reconcile per-item from the output. A passing validator promotes the item from UNVERIFIABLE to DONE; a failing one demotes to NOT DONE.
+
+**Honesty rule.** Do NOT classify an item as DONE just because related code shipped. Code that *handles* a deliverable is not the deliverable. Shipping a markdown-extraction library is not the same as shipping the markdown file. When in doubt between DONE and UNVERIFIABLE, prefer UNVERIFIABLE — better to surface a confirmation prompt than silently miss a deliverable.
+
+### Cross-Reference Against Diff
+
+Run `git diff origin/<base>...HEAD` and `git log origin/<base>..HEAD --oneline` to understand what was implemented.
+
+For each extracted plan item, run the verification dispatch from the previous section, then classify:
+
+- **DONE** — Clear evidence the item shipped. Cite the specific file(s) changed in the diff for DIFF-VERIFIABLE items, or the verified path that exists for CROSS-REPO items with a reachable sibling repo.
+- **PARTIAL** — Some work toward this item exists but is incomplete (e.g., model created but controller missing, function exists but edge cases not handled).
+- **NOT DONE** — Verification ran and produced negative evidence (file missing, code absent in diff, sibling-repo file confirmed absent).
+- **CHANGED** — The item was implemented using a different approach than the plan described, but the same goal is achieved. Note the difference.
+- **UNVERIFIABLE** — The diff and any reachable sibling-repo checks cannot prove or disprove this. Always applies to EXTERNAL-STATE items and to CROSS-REPO items where the sibling repo isn't reachable. Cite the specific manual verification the user must perform (e.g., "check Cloudflare DNS shows DNS-only mode for dashboard.example.com", "confirm /docs/dashboard.md exists in domain-hq repo").
+
+**Be conservative with DONE** — require clear evidence. A file being touched is not enough; the specific functionality described must be present.
+**Be generous with CHANGED** — if the goal is met by different means, that counts as addressed.
+**Be honest with UNVERIFIABLE** — better to surface 5 items the user must manually confirm than silently classify them DONE.

+─────────────────────────────────
+```
+
+### Gate Logic
+
+After producing the completion checklist, evaluate in priority order:
+
+1. **Any NOT DONE items** (highest priority — known missing work). Use AskUserQuestion:
+   - Show the completion checklist above
+   - "{N} items from the plan are NOT DONE. These were part of the original plan but are missing from the implementation."
+   - RECOMMENDATION: depends on item count and severity. If 1-2 minor items (docs, config), recommend B. If core functionality is missing, recommend A.
+   - Options:
+     A) Stop — implement the missing items before shipping
+     B) Ship anyway — defer these to a follow-up (will create P1 TODOs in Step 5.5)
+     C) These items were intentionally dropped — remove from scope
+   - If A: STOP. List the missing items for the user to implement.
+   - If B: Continue. For each NOT DONE item, create a P1 TODO in Step 5.5 with "Deferred from plan: {plan file path}".
+   - If C: Continue. Note in PR body: "Plan items intentionally dropped: {list}."
+
+2. **Any UNVERIFIABLE items** (silent gaps — the diff cannot prove them either way). Only fires after NOT DONE is resolved or absent.
+
+   **Per-item confirmation is mandatory.** Do NOT use a single AskUserQuestion to blanket-confirm all UNVERIFIABLE items. Blanket confirmation is the failure mode that surfaced in VAS-449 (user clicks A without opening any file). Instead:
+
+   - Loop through UNVERIFIABLE items one at a time.
+   - For each item, use AskUserQuestion with the item's *specific* manual check (e.g., "Confirm: does `~/Development/domain-hq/docs/dashboard.md` exist?", not "Have you checked all items?").
+   - Options per item:
+     Y) Confirmed done — cite what you verified (free-text, embedded in PR body)
+     N) Not done — block ship; treat as NOT DONE and re-enter the priority-1 gate
+     D) Intentionally dropped — note in PR body: "Plan item intentionally dropped: {item}"
+   - RECOMMENDATION per item: Y if the item is concrete and easily verified; N if it's critical-path (auth, DNS, deliverables to other repos) and the user shows hesitation.
+
+   **Exit conditions:**
+   - Any N: STOP. Surface the missing items, suggest re-running /ship after they're addressed.
+   - All Y or D: Continue. Embed `## Plan Completion — Manual Verifications` section in PR body listing each Y'd item with the user's free-text evidence and each D'd item with "intentionally dropped".
+
+   **Cap.** If there are more than 5 UNVERIFIABLE items, present them as a numbered list first and ask whether the user wants to (1) confirm each individually, (2) stop and reduce scope, or (3) explicitly accept blanket-confirmation with the warning that this is the VAS-449 failure shape. Default and recommended option is (1).
+
+3. **Only PARTIAL items (no NOT DONE, no UNVERIFIABLE):** Continue with a note in the PR body. Not blocking.
+
+4. **All DONE or CHANGED:** Pass. "Plan completion: PASS — all items addressed." Continue.
+
+**No plan file found:** Skip entirely. "No plan file detected — skipping plan completion audit."
+
+**Include in PR body (Step 8):** Add a `## Plan Completion` section with the checklist summary.
+>
+> After your analysis, output a single JSON object on the LAST LINE of your response (no other text after it):
+> `{"total_items":N,"done":N,"changed":N,"deferred":N,"unverifiable":N,"summary":"<markdown checklist for PR body>"}`
+
+**Parent processing:**
+
+1. Parse the LAST line of the subagent's output as JSON.
+2. Store `done`, `deferred`, `unverifiable` for Step 20 metrics; use `summary` in PR body.
+3. If `deferred > 0` or `unverifiable > 0` and no user override, present the items via the appropriate AskUserQuestion (see Gate Logic priority order above) before continuing.
+4. Embed `summary` in PR body's `## Plan Completion` section (Step 19). If `unverifiable > 0` and the user picked option A in the UNVERIFIABLE gate, also embed `## Plan Completion — Manual Verifications` listing each user-confirmed item.
+
+**If the subagent fails or returns invalid JSON:** Fall back to running the audit inline (parent processes the same plan-extraction + classification logic). If the inline fallback also fails (e.g., plan file unreadable, parser error), do NOT silently pass — surface the failure as an explicit AskUserQuestion: "Plan Completion audit could not run ({reason}). Options: (A) Skip audit and ship anyway — record that the audit was skipped in PR body and Step 20 metrics; (B) Stop and fix the audit." Default and recommended option is (B). Silent fail-open is the failure shape that VAS-449 surfaced.
+
+---
+
+## Step 8.1: Plan Verification
+
+Automatically verify the plan's testing/verification steps using the `/qa-only` skill.
+
+### 1. Check for verification section
+
+Using the plan file already discovered in Step 8, look for a verification section. Match any of these headings: `## Verification`, `## Test plan`, `## Testing`, `## How to test`, `## Manual testing`, or any section with verification-flavored items (URLs to visit, things to check visually, interactions to test).
+
+**If no verification section found:** Skip with "No verification steps found in plan — skipping auto-verification."
+**If no plan file was found in Step 8:** Skip (already handled).
+
+### 2. Check for running dev server
+
+Before invoking browse-based verification, check if a dev server is reachable:
+
+```bash
+curl -s -o /dev/null -w '%{http_code}' http://localhost:3000 2>/dev/null || \
+curl -s -o /dev/null -w '%{http_code}' http://localhost:8080 2>/dev/null || \
+curl -s -o /dev/null -w '%{http_code}' http://localhost:5173 2>/dev/null || \
+curl -s -o /dev/null -w '%{http_code}' http://localhost:4000 2>/dev/null || echo "NO_SERVER"
+```
+
+**If NO_SERVER:** Skip with "No dev server detected — skipping plan verification. Run /qa separately after deploying."
+
+### 3. Invoke /qa-only inline
+
+Read the `/qa-only` skill from disk:
+
+```bash
+cat ${CLAUDE_SKILL_DIR}/../qa-only/SKILL.md
+```
+
+**If unreadable:** Skip with "Could not load /qa-only — skipping plan verification."
+
+Follow the /qa-only workflow with these modifications:
+- **Skip the preamble** (already handled by /ship)
+- **Use the plan's verification section as the primary test input** — treat each verification item as a test case
+- **Use the detected dev server URL** as the base URL
+- **Skip the fix loop** — this is report-only verification during /ship
+- **Cap at the verification items from the plan** — do not expand into general site QA
+
+### 4. Gate logic
+
+- **All verification items PASS:** Continue silently. "Plan verification: PASS."
+- **Any FAIL:** Use AskUserQuestion:
+  - Show the failures with screenshot evidence
+  - RECOMMENDATION: Choose A if failures indicate broken functionality. Choose B if cosmetic only.
+  - Options:
+    A) Fix the failures before shipping (recommended for functional issues)
+    B) Ship anyway — known issues (acceptable for cosmetic issues)
+- **No verification section / no server / unreadable skill:** Skip (non-blocking).
+
+### 5. Include in PR body
+
+Add a `## Verification Results` section to the PR body (Step 19):
+- If verification ran: summary of results (N PASS, M FAIL, K SKIPPED)
+- If skipped: reason for skipping (no plan, no server, no verification section)
+
+## Prior Learnings
+
+Search for relevant learnings from previous sessions:
+
+```bash
+_CROSS_PROJ=$(~/.claude/skills/gstack/bin/gstack-config get cross_project_learnings 2>/dev/null || echo "unset")
+echo "CROSS_PROJECT: $_CROSS_PROJ"
+if [ "$_CROSS_PROJ" = "true" ]; then
+  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 --query "release ship version changelog merge pr" --cross-project 2>/dev/null || true
+else
+  ~/.claude/skills/gstack/bin/gstack-learnings-search --limit 10 --query "release ship version changelog merge pr" 2>/dev/null || true
+fi
+```
+
+If `CROSS_PROJECT` is `unset` (first time): Use AskUserQuestion:
+
+> gstack can search learnings from your other projects on this machine to find
+> patterns that might apply here. This stays local (no data leaves your machine).
+> Recommended for solo developers. Skip if you work on multiple client codebases
+> where cross-contamination would be a concern.
+
+Options:
+- A) Enable cross-project learnings (recommended)
+- B) Keep learnings project-scoped only
+
+If A: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings true`
+If B: run `~/.claude/skills/gstack/bin/gstack-config set cross_project_learnings false`
+
+Then re-run the search with the appropriate flag.
+
+If learnings are found, incorporate them into your analysis. When a review finding
+matches a past learning, display:
+
+**"Prior learning applied: [key] (confidence N/10, from [date])"**
+
+This makes the compounding visible. The user should see that gstack is getting
+smarter on their codebase over time.
+
+## Step 8.2: Scope Drift Detection
+
+Before reviewing code quality, check: **did they build what was requested — nothing more, nothing less?**
+
+1. Read `TODOS.md` (if it exists). Read PR description (`gh pr view --json body --jq .body 2>/dev/null || true`).
+   Read commit messages (`git log origin/<base>..HEAD --oneline`).
+   **If no PR exists:** rely on commit messages and TODOS.md for stated intent — this is the common case since /review runs before /ship creates the PR.
+2. Identify the **stated intent** — what was this branch supposed to accomplish?
+3. Run `DIFF_BASE=$(git merge-base origin/<base> HEAD) && git diff "$DIFF_BASE" --stat` and compare the files changed against the stated intent.
+
+4. Evaluate with skepticism (incorporating plan completion results if available from an earlier step or adjacent section):
+
+   **SCOPE CREEP detection:**
+   - Files changed that are unrelated to the stated intent
+   - New features or refactors not mentioned in the plan
+   - "While I was in there..." changes that expand blast radius
+
+   **MISSING REQUIREMENTS detection:**
+   - Requirements from TODOS.md/PR description not addressed in the diff
+   - Test coverage gaps for stated requirements
+   - Partial implementations (started but not finished)
+
+5. Output (before the main review begins):
+   \`\`\`
+   Scope Check: [CLEAN / DRIFT DETECTED / REQUIREMENTS MISSING]
+   Intent: <1-line summary of what was requested>
+   Delivered: <1-line summary of what the diff actually does>
+   [If drift: list each out-of-scope change]
+   [If missing: list each unaddressed requirement]
+   \`\`\`
+
+6. This is **INFORMATIONAL** — does not block the review. Proceed to the next step.

+## Step 8: Plan Completion Audit
+
+**Dispatch this step as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent reads the plan file and every referenced code file in its own fresh context. Parent gets only the conclusion.
+
+**Subagent prompt:** Pass these instructions to the subagent:
+
+> You are running a ship-workflow plan completion audit. The base branch is `<base>`. Use `git diff <base>...HEAD` to see what shipped. Do not commit or push — report only.
+>
+> {{PLAN_COMPLETION_AUDIT_SHIP}}

+> `{"total_items":N,"done":N,"changed":N,"deferred":N,"unverifiable":N,"summary":"<markdown checklist for PR body>"}`
+
+**Parent processing:**
+
+1. Parse the LAST line of the subagent's output as JSON.
+2. Store `done`, `deferred`, `unverifiable` for Step 20 metrics; use `summary` in PR body.
+3. If `deferred > 0` or `unverifiable > 0` and no user override, present the items via the appropriate AskUserQuestion (see Gate Logic priority order above) before continuing.
+4. Embed `summary` in PR body's `## Plan Completion` section (Step 19). If `unverifiable > 0` and the user picked option A in the UNVERIFIABLE gate, also embed `## Plan Completion — Manual Verifications` listing each user-confirmed item.
+
+**If the subagent fails or returns invalid JSON:** Fall back to running the audit inline (parent processes the same plan-extraction + classification logic). If the inline fallback also fails (e.g., plan file unreadable, parser error), do NOT silently pass — surface the failure as an explicit AskUserQuestion: "Plan Completion audit could not run ({reason}).

+## Step 18: Documentation sync (via subagent, before PR creation)
+
+**Dispatch /document-release as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent gets a fresh context window — zero rot from the preceding 17 steps. It also runs the **full** `/document-release` workflow (with CHANGELOG clobber protection, doc exclusions, risky-change gates, named staging, race-safe PR body editing) rather than a weaker reimplementation.
+
+**Sequencing:** This step runs AFTER Step 17 (Push) and BEFORE Step 19 (Create PR). The PR is created once from final HEAD with the `## Documentation` section baked into the initial body. No create-then-re-edit dance.
+
+**Subagent prompt:**
+
+> You are executing the /document-release workflow after a code push. Read the full skill file `${HOME}/.claude/skills/gstack/document-release/SKILL.md` and execute its complete workflow end-to-end, including CHANGELOG clobber protection, doc exclusions, risky-change gates, and named staging. Do NOT attempt to edit the PR body — no PR exists yet. Branch: `<branch>`, base: `<base>`.
+>
+> After completing the workflow, output a single JSON object on the LAST LINE of your response (no other text after it):
+> `{"files_updated":["README.md","CLAUDE.md",...],"commit_sha":"abc1234","pushed":true,"documentation_section":"<markdown block for PR body's ## Documentation section>"}`
+>
+> If no documentation files needed updating, output:
+> `{"files_updated":[],"commit_sha":null,"pushed":false,"documentation_section":null}`
+
+**Parent processing:**
+
+1. Parse the LAST line of the subagent's output as JSON.
+2. Store `documentation_section` — Step 19 embeds it in the PR body (or omits the section if null).
+3. If `files_updated` is non-empty, print: `Documentation synced: {files_updated.length} files updated, committed as {commit_sha}`.
+4. If `files_updated` is empty, print: `Documentation is current — no updates needed.`
+
+**If the subagent fails or returns invalid JSON:** Print a warning and proceed to Step 19 without a `## Documentation` section. Do not block /ship on subagent failure. The user can run `/document-release` manually after the PR lands.
+
+---
+
+## Step 19: Create PR/MR
+
+**Idempotency check:** Check if a PR/MR already exists for this branch.
+
+**If GitHub:**
+```bash
+gh pr view --json url,number,state -q 'if .state == "OPEN" then "PR #\(.number): \(.url)" else "NO_PR" end' 2>/dev/null || echo "NO_PR"
+```
+
+**If GitLab:**
+```bash
+glab mr view -F json 2>/dev/null | jq -r 'if .state == "opened" then "MR_EXISTS" else "NO_MR" end' 2>/dev/null || echo "NO_MR"
+```
+
+If an **open** PR/MR already exists: **update** the PR body using `gh pr edit --body-file "$PR_BODY_FILE"` (GitHub) or `glab mr update -d ...` (GitLab). Always regenerate the PR body from scratch using this run's fresh results (test output, coverage audit, review findings, adversarial review, TODOS summary, documentation_section from Step 18). Never reuse stale PR body content from a prior run. **Run the same redaction scan-at-sink (PR body + title) as the create path (Step 19) before editing — scan the temp file, then `gh pr edit --body-file` from it.**
+
+**Always update the PR title to start with `v$NEW_VERSION`.** PR titles use the workspace-aware format `v<NEW_VERSION> <type>: <summary>` — version ALWAYS first, no exceptions, no "custom title kept intentionally" escape hatch. The shared helper `bin/gstack-pr-title-rewrite.sh` is the single source of truth for the rule.
+
+1. Read the current title: `CURRENT=$(gh pr view --json title -q .title)` (or `glab mr view -F json | jq -r .title`).
+2. Compute the corrected title: `NEW_TITLE=$(~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh "$NEW_VERSION" "$CURRENT")`. The helper handles three cases: title already correct (no-op), title has a different `v<X.Y.Z.W>` prefix (replace it), or title has no version prefix (prepend one).
+3. If `NEW_TITLE` differs from `CURRENT`, run `gh pr edit --title "$NEW_TITLE"` (or `glab mr update -t "$NEW_TITLE"`).
+4. **Self-check:** re-fetch the title and assert it starts with `v$NEW_VERSION `. If it does not, retry the edit once. If still wrong, surface the failure to the user.
+
+This keeps the title truthful when Step 12's queue-drift detection rebumps a stale version, and forces the format on PRs that were created without it.
+
+Print the existing URL and continue to Step 20.
+
+If no PR/MR exists: create a pull request (GitHub) or merge request (GitLab) using the platform detected in Step 0.
+
+The PR/MR body should contain these sections:
+
+```
+## Summary
+<Summarize ALL changes being shipped. Run `git log <base>..HEAD --oneline` to enumerate
+every commit. Exclude the VERSION/CHANGELOG metadata commit (that's this PR's bookkeeping,
+not a substantive change). Group the remaining commits into logical sections (e.g.,
+"**Performance**", "**Dead Code Removal**", "**Infrastructure**"). Every substantive commit
+must appear in at least one section. If a commit's work isn't reflected in the summary,

+
+The PR body is world-readable on a public repo. Scan-at-sink before sending:
+write the composed body to a temp file, scan THAT file with the shared engine,
+and pass the same file to `gh`/`glab`. Wrap any Codex / Greptile / eval output
+sections in tool-attributed fences (` ```codex-review ` / ` ```greptile `) so the

+
+HIGH blocks (exit 3, no skip). MEDIUM → AskUserQuestion (PII subset offers

+## Step 18: Documentation sync (via subagent, before PR creation)
+
+**Dispatch /document-release as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent gets a fresh context window — zero rot from the preceding 17 steps. It also runs the **full** `/document-release` workflow (with CHANGELOG clobber protection, doc exclusions, risky-change gates, named staging, race-safe PR body editing) rather than a weaker reimplementation.
+
+**Sequencing:** This step runs AFTER Step 17 (Push) and BEFORE Step 19 (Create PR). The PR is created once from final HEAD with the `## Documentation` section baked into the initial body. No create-then-re-edit dance.
+
+**Subagent prompt:**
+
+> You are executing the /document-release workflow after a code push. Read the full skill file `${HOME}/.claude/skills/gstack/document-release/SKILL.md` and execute its complete workflow end-to-end, including CHANGELOG clobber protection, doc exclusions, risky-change gates, and named staging. Do NOT attempt to edit the PR body — no PR exists yet. Branch: `<branch>`, base: `<base>`.
+>
+> After completing the workflow, output a single JSON object on the LAST LINE of your response (no other text after it):
+> `{"files_updated":["README.md","CLAUDE.md",...],"commit_sha":"abc1234","pushed":true,"documentation_section":"<markdown block for PR body's ## Documentation section>"}`
+>
+> If no documentation files needed updating, output:
+> `{"files_updated":[],"commit_sha":null,"pushed":false,"documentation_section":null}`
+
+**Parent processing:**
+
+1. Parse the LAST line of the subagent's output as JSON.
+2. Store `documentation_section` — Step 19 embeds it in the PR body (or omits the section if null).
+3. If `files_updated` is non-empty, print: `Documentation synced: {files_updated.length} files updated, committed as {commit_sha}`.
+4. If `files_updated` is empty, print: `Documentation is current — no updates needed.`
+
+**If the subagent fails or returns invalid JSON:** Print a warning and proceed to Step 19 without a `## Documentation` section. Do not block /ship on subagent failure. The user can run `/document-release` manually after the PR lands.
+
+---
+
+## Step 19: Create PR/MR
+
+**Idempotency check:** Check if a PR/MR already exists for this branch.
+
+**If GitHub:**
+```bash
+gh pr view --json url,number,state -q 'if .state == "OPEN" then "PR #\(.number): \(.url)" else "NO_PR" end' 2>/dev/null || echo "NO_PR"
+```
+
+**If GitLab:**
+```bash
+glab mr view -F json 2>/dev/null | jq -r 'if .state == "opened" then "MR_EXISTS" else "NO_MR" end' 2>/dev/null || echo "NO_MR"
+```
+
+If an **open** PR/MR already exists: **update** the PR body using `gh pr edit --body-file "$PR_BODY_FILE"` (GitHub) or `glab mr update -d ...` (GitLab). Always regenerate the PR body from scratch using this run's fresh results (test output, coverage audit, review findings, adversarial review, TODOS summary, documentation_section from Step 18). Never reuse stale PR body content from a prior run. **Run the same redaction scan-at-sink (PR body + title) as the create path (Step 19) before editing — scan the temp file, then `gh pr edit --body-file` from it.**
+
+**Always update the PR title to start with `v$NEW_VERSION`.** PR titles use the workspace-aware format `v<NEW_VERSION> <type>: <summary>` — version ALWAYS first, no exceptions, no "custom title kept intentionally" escape hatch. The shared helper `bin/gstack-pr-title-rewrite.sh` is the single source of truth for the rule.
+
+1. Read the current title: `CURRENT=$(gh pr view --json title -q .title)` (or `glab mr view -F json | jq -r .title`).
+2. Compute the corrected title: `NEW_TITLE=$(~/.claude/skills/gstack/bin/gstack-pr-title-rewrite.sh "$NEW_VERSION" "$CURRENT")`. The helper handles three cases: title already correct (no-op), title has a different `v<X.Y.Z.W>` prefix (replace it), or title has no version prefix (prepend one).
+3. If `NEW_TITLE` differs from `CURRENT`, run `gh pr edit --title "$NEW_TITLE"` (or `glab mr update -t "$NEW_TITLE"`).
+4. **Self-check:** re-fetch the title and assert it starts with `v$NEW_VERSION `. If it does not, retry the edit once. If still wrong, surface the failure to the user.
+
+This keeps the title truthful when Step 12's queue-drift detection rebumps a stale version, and forces the format on PRs that were created without it.
+
+Print the existing URL and continue to Step 20.
+
+If no PR/MR exists: create a pull request (GitHub) or merge request (GitLab) using the platform detected in Step 0.
+
+The PR/MR body should contain these sections:
+
+```
+## Summary
+<Summarize ALL changes being shipped. Run `git log <base>..HEAD --oneline` to enumerate
+every commit. Exclude the VERSION/CHANGELOG metadata commit (that's this PR's bookkeeping,

+## Step 9: Pre-Landing Review
+
+Review the diff for structural issues that tests don't catch.
+
+1. Read `.claude/skills/review/checklist.md`. If the file cannot be read, **STOP** and report the error.
+
+2. Run `git diff origin/<base>` to get the full diff (scoped to feature changes against the freshly-fetched base branch).
+
+3. Apply the review checklist in two passes:
+   - **Pass 1 (CRITICAL):** SQL & Data Safety, LLM Output Trust Boundary
+   - **Pass 2 (INFORMATIONAL):** All remaining categories
+
+## Confidence Calibration
+
+Every finding MUST include a confidence score (1-10):
+
+| Score | Meaning | Display rule |
+|-------|---------|-------------|
+| 9-10 | Verified by reading specific code. Concrete bug or exploit demonstrated. | Show normally |
+| 7-8 | High confidence pattern match. Very likely correct. | Show normally |
+| 5-6 | Moderate. Could be a false positive. | Show with caveat: "Medium confidence, verify this is actually an issue" |
+| 3-4 | Low confidence. Pattern is suspicious but may be fine. | Suppress from main report. Include in appendix only. |
+| 1-2 | Speculation. | Only report if severity would be P0. |
+
+**Finding format:**
+
+\`[SEVERITY] (confidence: N/10) file:line — description\`
+
+Example:
+\`[P1] (confidence: 9/10) app/models/user.rb:42 — SQL injection via string interpolation in where clause\`
+\`[P2] (confidence: 5/10) app/controllers/api/v1/users_controller.rb:18 — Possible N+1 query, verify with production logs\`
+
+### Pre-emit verification gate (#1539 — kills the "field doesn't exist" FP class)
+
+Before any finding is promoted to the report, the gate requires:
+
+1. **Quote the specific code line that motivates the finding** — file:line plus
+   the verbatim text of the line(s) that triggered it. If the finding is "field
+   X doesn't exist on model Y", quote the lines of class Y where the field
+   would live. If "dict.get() might return None", quote the dict initialization.
+   If "race condition between A and B", quote both A and B.
+
+2. **If you cannot quote the motivating line(s), the finding is unverified.**
+   Force its confidence to 4-5 (suppressed from the main report). It still goes
+   into the appendix so reviewers can audit calibration, but the user does NOT
+   see it in the critical-pass output. Do not work around this by inventing
+   speculative confidence 7+ — that defeats the gate.
+
+**Framework-meta nudge:** When the symbol is generated by a framework
+metaclass, descriptor, ORM Meta inner-class, or migration history (Django
+`Meta`, Rails `has_many`/`scope`, SQLAlchemy `relationship`/`Column`,
+TypeORM decorators, Sequelize `init`/`belongsTo`, Prisma generated client),
+quote the meta-construct (the `Meta` block, the migration, the decorator,
+the schema file) instead of expecting the literal name in the class body.
+The verification is "I read the source that creates this symbol", not "I
+grep'd for the name and didn't find it." Deeper framework-aware verification
+(model introspection, migration-history-aware checks, ORM dialect detection)
+is deliberately out of scope for the lighter gate — see the deferred
+`~/.gstack-dev/plans/1539-framework-aware-review.md` design doc.
+
+The FP classes the gate kills (measured against Django Sprint 2.5 #1539):
+
+| FP class | Why the gate catches it |
+|---|---|
+| "field doesn't exist on model" | Requires quoting the model class body or Meta; the field's absence becomes obvious |
+| "dict.get() might be None" | Requires quoting the dict initialization (e.g. Django form's `cleaned_data` is `{}`-initialized) |
+| "save() might lose fields" | Requires quoting the ORM signature or model definition |
+| "update_fields might miss X" | Requires quoting the field set; if X doesn't exist, the FP is self-evident |
+
+**Calibration learning:** If you report a finding with confidence < 7 and the user
+confirms it IS a real issue, that is a calibration event. Your initial confidence was
+too low. Log the corrected pattern as a learning so future reviews catch it with
+higher confidence.
+
+## Design Review (conditional, diff-scoped)
+
+Check if the diff touches frontend files using `gstack-diff-scope`:
+
+```bash
+source <(~/.claude/skills/gstack/bin/gstack-diff-scope <base> 2>/dev/null)
+```
+
+**If `SCOPE_FRONTEND=false`:** Skip design review silently. No output.
+
+**If `SCOPE_FRONTEND=true`:**
+
+1. **Check for DESIGN.md.** If `DESIGN.md` or `design-system.md` exists in the repo root, read it. All design findings are calibrated against it — patterns blessed in DESIGN.md are not flagged. If not found, use universal design principles.
+
+2. **Read `.claude/skills/review/design-checklist.md`.** If the file cannot be read, skip design review with a note: "Design checklist not found — skipping design review."
+
+3. **Read each changed frontend file** (full file, not just diff hunks). Frontend files are identified by the patterns listed in the checklist.
+
+4. **Apply the design checklist** against the changed files. For each item:
+   - **[HIGH] mechanical CSS fix** (`outline: none`, `!important`, `font-size < 16px`): classify as AUTO-FIX
+   - **[HIGH/MEDIUM] design judgment needed**: classify as ASK
+   - **[LOW] intent-based detection**: present as "Possible — verify visually or run /design-review"
+
+5. **Include findings** in the review output under a "Design Review" header, following the output format in the checklist. Design findings merge with code review findings into the same Fix-First flow.
+
+6. **Log the result** for the Review Readiness Dashboard:
+
+```bash
+~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"design-review-lite","timestamp":"TIMESTAMP","status":"STATUS","findings":N,"auto_fixed":M,"commit":"COMMIT"}'
+```
+
+Substitute: TIMESTAMP = ISO 8601 datetime, STATUS = "clean" if 0 findings or "issues_found", N = total findings, M = auto-fixed count, COMMIT = output of `git rev-parse --short HEAD`.
+
+7. **Codex design voice** (optional, automatic if available):
+
+```bash
+command -v codex >/dev/null 2>&1 && echo "CODEX_AVAILABLE" || echo "CODEX_NOT_AVAILABLE"
+```
+
+If Codex is available, run a lightweight design check on the diff:
+
+```bash
+TMPERR_DRL=$(mktemp /tmp/codex-drl-XXXXXXXX)
+_REPO_ROOT=$(git rev-parse --show-toplevel) || { echo "ERROR: not in a git repo" >&2; exit 1; }
+codex exec "Review the git diff on this branch. Run 7 litmus checks (YES/NO each): 1. Brand/product unmistakable in first screen? 2. One strong visual anchor present? 3. Page understandable by scanning headlines only? 4. Each section has one job? 5. Are cards actually necessary? 6. Does motion improve hierarchy or atmosphere? 7. Would design feel premium with all decorative shadows removed? Flag any hard rejections: 1. Generic SaaS card grid as first impression 2. Beautiful image with weak brand 3.

+```
+
+Use a 5-minute timeout (`timeout: 300000`). After the command completes, read stderr:
+```bash
+cat "$TMPERR_DRL" && rm -f "$TMPERR_DRL"
+```
+
+**Error handling:** All errors are non-blocking. On auth failure, timeout, or empty response — skip with a brief note and continue.
+
+Present Codex output under a `CODEX (design):` header, merged with the checklist findings above.
+
+   Include any design findings alongside the code review findings. They follow the same Fix-First flow below.

+2. **Maintainability** — read `~/.claude/skills/gstack/review/specialists/maintainability.md`
+
+**If DIFF_LINES < 50:** Skip all specialists. Print: "Small diff ($DIFF_LINES lines) — specialists skipped." Continue to the Fix-First flow (item 4).
+
+**Conditional (dispatch if the matching scope signal is true):**
+3. **Security** — if SCOPE_AUTH=true, OR if SCOPE_BACKEND=true AND DIFF_LINES > 100. Read `~/.claude/skills/gstack/review/specialists/security.md`
+4. **Performance** — if SCOPE_BACKEND=true OR SCOPE_FRONTEND=true. Read `~/.claude/skills/gstack/review/specialists/performance.md`
+5. **Data Migration** — if SCOPE_MIGRATIONS=true. Read `~/.claude/skills/gstack/review/specialists/data-migration.md`
+6. **API Contract** — if SCOPE_API=true. Read `~/.claude/skills/gstack/review/specialists/api-contract.md`
+7. **Design** — if SCOPE_FRONTEND=true. Use the existing design review checklist at `~/.claude/skills/gstack/review/design-checklist.md`
+
+### Adaptive gating
+
+After scope-based selection, apply adaptive gating based on specialist hit rates:
+
+For each conditional specialist that passed scope gating, check the `gstack-specialist-stats` output above:
+- If tagged `[GATE_CANDIDATE]` (0 findings in 10+ dispatches): skip it. Print: "[specialist] auto-gated (0 findings in N reviews)."
+- If tagged `[NEVER_GATE]`: always dispatch regardless of hit rate. Security and data-migration are insurance policy specialists — they should run even when silent.
+
+**Force flags:** If the user's prompt includes `--security`, `--performance`, `--testing`, `--maintainability`, `--data-migration`, `--api-contract`, `--design`, or `--all-specialists`, force-include that specialist regardless of gating.
+
+Note which specialists were selected, gated, and skipped. Print the selection:
+"Dispatching N specialists: [names]. Skipped: [names] (scope not detected). Gated: [names] (0 findings in N+ reviews)."
+
+---
+
+### Dispatch specialists in parallel
+
+For each selected specialist, launch an independent subagent via the Agent tool.
+**Launch ALL selected specialists in a single message** (multiple Agent tool calls)
+so they run in parallel. Each subagent has fresh context — no prior review bias.
+
+**Each specialist subagent prompt:**
+
+Construct the prompt for each specialist. The prompt includes:
+
+1. The specialist's checklist content (you already read the file above)
+2. Stack context: "This is a {STACK} project."
+3. Past learnings for this domain (if any exist):
+
+```bash
+~/.claude/skills/gstack/bin/gstack-learnings-search --type pitfall --query "{specialist domain}" --limit 5 2>/dev/null || true
+```
+
+If learnings are found, include them: "Past learnings for this domain: {learnings}"
+
+4. Instructions:
+
+"You are a specialist code reviewer. Read the checklist below, then run
+`DIFF_BASE=$(git merge-base origin/<base> HEAD) && git diff "$DIFF_BASE"` to get the full diff. Apply the checklist against the diff.
+
+For each finding, output a JSON object on its own line:
+{\"severity\":\"CRITICAL|INFORMATIONAL\",\"confidence\":N,\"path\":\"file\",\"line\":N,\"category\":\"category\",\"summary\":\"description\",\"fix\":\"recommended fix\",\"fingerprint\":\"path:line:category\",\"specialist\":\"name\"}
+
+Required fields: severity, confidence, path, category, summary, specialist.
+Optional: line, fix, fingerprint, evidence, test_stub.
+
+If you can write a test that would catch this issue, include it in the `test_stub` field.
+Use the detected test framework ({TEST_FW}). Write a minimal skeleton — describe/it/test
+blocks with clear intent. Skip test_stub for architectural or design-only findings.
+
+If no findings: output `NO FINDINGS` and nothing else.
+Do not output anything else — no preamble, no summary, no commentary.
+
+Stack context: {STACK}
+Past learnings: {learnings or 'none'}
+
+CHECKLIST:
+{checklist content}"
+
+**Subagent configuration:**
+- Use `subagent_type: "general-purpose"`
+- Do NOT use `run_in_background` — all specialists must complete before merge
+- If any specialist subagent fails or times out, log the failure and continue with results from successful specialists. Specialists are additive — partial results are better than no results.
+
+---
+
+### Step 9.2: Collect and merge findings
+
+After all specialist subagents complete, collect their outputs.
+
+**Parse findings:**
+For each specialist's output:
+1. If output is "NO FINDINGS" — skip, this specialist found nothing
+2. Otherwise, parse each line as a JSON object. Skip lines that are not valid JSON.
+3. Collect all parsed findings into a single list, tagged with their specialist name.
+
+**Fingerprint and deduplicate:**
+For each finding, compute its fingerprint:
+- If `fingerprint` field is present, use it
+- Otherwise: `{path}:{line}:{category}` (if line is present) or `{path}:{category}`
+
+Group findings by fingerprint. For findings sharing the same fingerprint:
+- Keep the finding with the highest confidence score
+- Tag it: "MULTI-SPECIALIST CONFIRMED ({specialist1} + {specialist2})"
+- Boost confidence by +1 (cap at 10)
+- Note the confirming specialists in the output
+
+**Apply confidence gates:**
+- Confidence 7+: show normally in the findings output
+- Confidence 5-6: show with caveat "Medium confidence — verify this is actually an issue"
+- Confidence 3-4: move to appendix (suppress from main findings)
+- Confidence 1-2: suppress entirely
+
+**Compute PR Quality Score:**
+After merging, compute the quality score:
+`quality_score = max(0, 10 - (critical_count * 2 + informational_count * 0.5))`
+Cap at 10. Log this in the review result at the end.
+
+**Output merged findings:**
+Present the merged findings in the same format as the current review:
+
+```
+SPECIALIST REVIEW: N findings (X critical, Y informational) from Z specialists
+
+[For each finding, in order: CRITICAL first, then INFORMATIONAL, sorted by confidence descending]
+[SEVERITY] (confidence: N/10, specialist: name) path:line — summary
+  Fix: recommended fix
+  [If MULTI-SPECIALIST CONFIRMED: show confirmation note]
+
+PR Quality Score: X/10
+```
+
+These findings flow into the Fix-First flow (item 4) alongside the checklist pass (Step 9).
+The Fix-First heuristic applies identically — specialist findings follow the same AUTO-FIX vs ASK classification.
+
+**Compile per-specialist stats:**
+After merging findings, compile a `specialists` object for the review-log persist.
+For each specialist (testing, maintainability, security, performance, data-migration, api-contract, design, red-team):
+- If dispatched: `{"dispatched": true, "findings": N, "critical": N, "informational": N}`
+- If skipped by scope: `{"dispatched": false, "reason": "scope"}`
+- If skipped by gating: `{"dispatched": false, "reason": "gated"}`
+- If not applicable (e.g., red-team not activated): omit from the object
+
+Include the Design specialist even though it uses `design-checklist.md` instead of the specialist schema files.
+Remember these stats — you will need them for the review-log entry in Step 5.8.
+
+---
+
+### Red Team dispatch (conditional)
+
+**Activation:** Only if DIFF_LINES > 200 OR any specialist produced a CRITICAL finding.
+
+If activated, dispatch one more subagent via the Agent tool (foreground, not background).
+
+The Red Team subagent receives:
+1. The red-team checklist from `~/.claude/skills/gstack/review/specialists/red-team.md`
+2. The merged specialist findings from Step 9.2 (so it knows what was already caught)
+3. The git diff command
+
+Prompt: "You are a red team reviewer. The code has already been reviewed by N specialists
+who found the following issues: {merged findings summary}. Your job is to find what they
+MISSED. Read the checklist, run `DIFF_BASE=$(git merge-base origin/<base> HEAD) && git diff "$DIFF_BASE"`, and look for gaps.
+Output findings as JSON objects (same schema as the specialists). Focus on cross-cutting
+concerns, integration boundary issues, and failure modes that specialist checklists
+don't cover."
+
+If the Red Team finds additional issues, merge them into the findings list before
+the Fix-First flow (item 4). Red Team findings are tagged with `"specialist":"red-team"`.
+
+If the Red Team returns NO FINDINGS, note: "Red Team review: no additional issues found."
+If the Red Team subagent fails or times out, skip silently and continue.
+
+### Step 9.3: Cross-review finding dedup
+
+Before classifying findings, check if any were previously skipped by the user in a prior review on this branch.
+
+```bash
+~/.claude/skills/gstack/bin/gstack-review-read
+```
+
+Parse the output: only lines BEFORE `---CONFIG---` are JSONL entries (the output also contains `---CONFIG---` and `---HEAD---` footer sections that are not JSONL — ignore those).
+
+For each JSONL entry that has a `findings` array:
+1. Collect all fingerprints where `action: "skipped"`
+2. Note the `commit` field from that entry
+
+If skipped fingerprints exist, get the list of files changed since that review:
+
+```bash
+git diff --name-only <prior-review-commit> HEAD
+```
+
+For each current finding (from both the checklist pass (Step 9) and specialist review (Step 9.1-9.2)), check:
+- Does its fingerprint match a previously skipped finding?
+- Is the finding's file path NOT in the changed-files set?
+
+If both conditions are true: suppress the finding. It was intentionally skipped and the relevant code hasn't changed.
+
+Print: "Suppressed N findings from prior reviews (previously skipped by user)"
+
+**Only suppress `skipped` findings — never `fixed` or `auto-fixed`** (those might regress and should be re-checked).
+
+If no prior reviews exist or none have a `findings` array, skip this step silently.
+
+Output a summary header: `Pre-Landing Review: N issues (X critical, Y informational)`
+
+4. **Classify each finding from both the checklist pass and specialist review (Step 9.1-Step 9.2) as AUTO-FIX or ASK** per the Fix-First Heuristic in
+   checklist.md. Critical findings lean toward ASK; informational lean toward AUTO-FIX.
+
+5. **Auto-fix all AUTO-FIX items.** Apply each fix. Output one line per fix:
+   `[AUTO-FIXED] [file:line] Problem → what you did`
+
+6. **If ASK items remain,** present them in ONE AskUserQuestion:
+   - List each with number, severity, problem, recommended fix
+   - Per-item options: A) Fix  B) Skip
+   - Overall RECOMMENDATION
+   - If 3 or fewer ASK items, you may use individual AskUserQuestion calls instead
+
+7. **After all fixes (auto + user-approved):**
+   - If ANY fixes were applied: commit fixed files by name (`git add <fixed-files> && git commit -m "fix: pre-landing review fixes"`), then **STOP** and tell the user to run `/ship` again to re-test.
+   - If no fixes applied (all ASK items skipped, or no issues found): continue to Step 12.
+
+8. Output summary: `Pre-Landing Review: N issues — M auto-fixed, K asked (J fixed, L skipped)`
+
+   If no issues found: `Pre-Landing Review: No issues found.`
+
+9. Persist the review result to the review log:
+```bash
+~/.claude/skills/gstack/bin/gstack-review-log '{"skill":"review","timestamp":"TIMESTAMP","status":"STATUS","issues_found":N,"critical":N,"informational":N,"quality_score":SCORE,"specialists":SPECIALISTS_JSON,"findings":FINDINGS_JSON,"commit":"'"$(git rev-parse --short HEAD)"'","via":"ship"}'
+```
+Substitute TIMESTAMP (ISO 8601), STATUS ("clean" if no issues, "issues_found" otherwise),
+and N values from the summary counts above. The `via:"ship"` distinguishes from standalone `/review` runs.
+- `quality_score` = the PR Quality Score computed in Step 9.2 (e.g., 7.5). If specialists were skipped (small diff), use `10.0`
+- `specialists` = the per-specialist stats object compiled in Step 9.2. Each specialist that was considered gets an entry: `{"dispatched":true/false,"findings":N,"critical":N,"informational":N}` if dispatched, or `{"dispatched":false,"reason":"scope|gated"}` if skipped. Example: `{"testing":{"dispatched":true,"findings":2,"critical":0,"informational":2},"security":{"dispatched":false,"reason":"scope"}}`
+- `findings` = array of per-finding records. For each finding (from checklist pass and specialists), include: `{"fingerprint":"path:line:category","severity":"CRITICAL|INFORMATIONAL","action":"ACTION"}`. ACTION is `"auto-fixed"`, `"fixed"` (user approved), or `"skipped"` (user chose Skip).
+
+Save the review output — it goes into the PR body in Step 19.

+## Step 7: Test Coverage Audit
+
+**Dispatch this step as a subagent** using the Agent tool with `subagent_type: "general-purpose"`. The subagent runs the coverage audit in a fresh context window — the parent only sees the conclusion, not intermediate file reads. This is context-rot defense.
+
+**Subagent prompt:** Pass the following instructions to the subagent, with `<base>` substituted with the base branch:
+
+> You are running a ship-workflow test coverage audit. Run `git diff <base>...HEAD` as needed. Do not commit or push — report only.
+>
+> 100% coverage is the goal — every untested path is a path where bugs hide and vibe coding becomes yolo coding. Evaluate what was ACTUALLY coded (from the diff), not what was planned.
+
+### Test Framework Detection
+
+Before analyzing coverage, detect the project's test framework:
+
+1. **Read CLAUDE.md** — look for a `## Testing` section with test command and framework name. If found, use that as the authoritative source.
+2. **If CLAUDE.md has no testing section, auto-detect:**
+
+```bash
+setopt +o nomatch 2>/dev/null || true  # zsh compat
+# Detect project runtime
+[ -f Gemfile ] && echo "RUNTIME:ruby"
+[ -f package.json ] && echo "RUNTIME:node"
+[ -f requirements.txt ] || [ -f pyproject.toml ] && echo "RUNTIME:python"
+[ -f go.mod ] && echo "RUNTIME:go"
+[ -f Cargo.toml ] && echo "RUNTIME:rust"
+# Check for existing test infrastructure
+ls jest.config.* vitest.config.* playwright.config.* cypress.config.* .rspec pytest.ini phpunit.xml 2>/dev/null
+ls -d test/ tests/ spec/ __tests__/ cypress/ e2e/ 2>/dev/null
+```
+
+3. **If no framework detected:** falls through to the Test Framework Bootstrap step (Step 4) which handles full setup.
+
+**0. Before/after test count:**
+
+```bash
+# Count test files before any generation
+find . -name '*.test.*' -o -name '*.spec.*' -o -name '*_test.*' -o -name '*_spec.*' | grep -v node_modules | wc -l
+```
+
+Store this number for the PR body.
+
+**1. Trace every codepath changed** using `git diff origin/<base>...HEAD`:
+
+Read every changed file. For each one, trace how data flows through the code — don't just list functions, actually follow the execution:
+
+1. **Read the diff.** For each changed file, read the full file (not just the diff hunk) to understand context.
+2. **Trace data flow.** Starting from each entry point (route handler, exported function, event listener, component render), follow the data through every branch:
+   - Where does input come from? (request params, props, database, API call)
+   - What transforms it? (validation, mapping, computation)
+   - Where does it go? (database write, API response, rendered output, side effect)
+   - What can go wrong at each step? (null/undefined, invalid input, network failure, empty collection)
+3. **Diagram the execution.** For each changed file, draw an ASCII diagram showing:
+   - Every function/method that was added or modified
+   - Every conditional branch (if/else, switch, ternary, guard clause, early return)
+   - Every error path (try/catch, rescue, error boundary, fallback)
+   - Every call to another function (trace into it — does IT have untested branches?)
+   - Every edge: what happens with null input? Empty array? Invalid type?
+
+This is the critical step — you're building a map of every line of code that can execute differently based on input. Every branch in this diagram needs a test.
+
+**2. Map user flows, interactions, and error states:**
+
+Code coverage isn't enough — you need to cover how real users interact with the changed code. For each changed feature, think through:
+
+- **User flows:** What sequence of actions does a user take that touches this code? Map the full journey (e.g., "user clicks 'Pay' → form validates → API call → success/failure screen"). Each step in the journey needs a test.
+- **Interaction edge cases:** What happens when the user does something unexpected?
+  - Double-click/rapid resubmit
+  - Navigate away mid-operation (back button, close tab, click another link)
+  - Submit with stale data (page sat open for 30 minutes, session expired)
+  - Slow connection (API takes 10 seconds — what does the user see?)
+  - Concurrent actions (two tabs, same form)
+- **Error states the user can see:** For every error the code handles, what does the user actually experience?
+  - Is there a clear error message or a silent failure?
+  - Can the user recover (retry, go back, fix input) or are they stuck?
+  - What happens with no network? With a 500 from the API? With invalid data from the server?
+- **Empty/zero/boundary states:** What does the UI show with zero results? With 10,000 results? With a single character input? With maximum-length input?
+
+Add these to your diagram alongside the code branches. A user flow with no test is just as much a gap as an untested if/else.
+
+**3. Check each branch against existing tests:**
+
+Go through your diagram branch by branch — both code paths AND user flows. For each one, search for a test that exercises it:
+- Function `processPayment()` → look for `billing.test.ts`, `billing.spec.ts`, `test/billing_test.rb`
+- An if/else → look for tests covering BOTH the true AND false path
+- An error handler → look for a test that triggers that specific error condition
+- A call to `helperFn()` that has its own branches → those branches need tests too
+- A user flow → look for an integration or E2E test that walks through the journey
+- An interaction edge case → look for a test that simulates the unexpected action
+
+Quality scoring rubric:
+- ★★★  Tests behavior with edge cases AND error paths
+- ★★   Tests correct behavior, happy path only
+- ★    Smoke test / existence check / trivial assertion (e.g., "it renders", "it doesn't throw")
+
+### E2E Test Decision Matrix
+
+When checking each branch, also determine whether a unit test or E2E/integration test is the right tool:
+
+**RECOMMEND E2E (mark as [→E2E] in the diagram):**
+- Common user flow spanning 3+ components/services (e.g., signup → verify email → first login)
+- Integration point where mocking hides real failures (e.g., API → queue → worker → DB)
+- Auth/payment/data-destruction flows — too important to trust unit tests alone
+
+**RECOMMEND EVAL (mark as [→EVAL] in the diagram):**
+- Critical LLM call that needs a quality eval (e.g., prompt change → test output still meets quality bar)
+- Changes to prompt templates, system instructions, or tool definitions
+
+**STICK WITH UNIT TESTS:**
+- Pure function with clear inputs/outputs
+- Internal helper with no side effects
+- Edge case of a single function (null input, empty array)
+- Obscure/rare flow that isn't customer-facing
+
+### REGRESSION RULE (mandatory)
+
+**IRON RULE:** When the coverage audit identifies a REGRESSION — code that previously worked but the diff broke — a regression test is written immediately. No AskUserQuestion. No skipping. Regressions are the highest-priority test because they prove something broke.
+
+A regression is when:
+- The diff modifies existing behavior (not new code)
+- The existing test suite (if any) doesn't cover the changed path
+- The change introduces a new failure mode for existing callers
+
+When uncertain whether a change is a regression, err on the side of writing the test.
+
+Format: commit as `test: regression test for {what broke}`
+
+**4. Output ASCII coverage diagram:**
+
+Include BOTH code paths and user flows in the same diagram. Mark E2E-worthy and eval-worthy paths:
+
+```

+**Fast path:** All paths covered → "Step 7: All new code paths have test coverage ✓" Continue.
+
+**5. Generate tests for uncovered paths:**
+
+If test framework detected (or bootstrapped in Step 4):
+- Prioritize error handlers and edge cases first (happy paths are more likely already tested)
+- Read 2-3 existing test files to match conventions exactly
+- Generate unit tests. Mock all external dependencies (DB, API, Redis).
+- For paths marked [→E2E]: generate integration/E2E tests using the project's E2E framework (Playwright, Cypress, Capybara, etc.)
+- For paths marked [→EVAL]: generate eval tests using the project's eval framework, or flag for manual eval if none exists
+- Write tests that exercise the specific uncovered path with real assertions
+- Run each test. Passes → commit as `test: coverage for {feature}`
+- Fails → fix once. Still fails → revert, note gap in diagram.
+
+Caps: 30 code paths max, 20 tests generated max (code + user flow combined), 2-min per-test exploration cap.
+
+If no test framework AND user declined bootstrap → diagram only, no generation. Note: "Test generation skipped — no test framework configured."
+
+**Diff is test-only changes:** Skip Step 7 entirely: "No new application code paths to audit."
+
+**6. After-count and coverage summary:**

+```bash
+# Count test files after generation
+find . -name '*.test.*' -o -name '*.spec.*' -o -name '*_test.*' -o -name '*_spec.*' | grep -v node_modules | wc -l

+
+For PR body: `Tests: {before} → {after} (+{delta} new)`
+Coverage line: `Test Coverage Audit: N new code paths. M covered (X%). K tests generated, J committed.`
+
+**7. Coverage gate:**
+
+Before proceeding, check CLAUDE.md for a `## Test Coverage` section with `Minimum:` and `Target:` fields. If found, use those percentages. Otherwise use defaults: Minimum = 60%, Target = 80%.
+
+Using the coverage percentage from the diagram in substep 4 (the `COVERAGE: X/Y (Z%)` line):
+
+- **>= target:** Pass. "Coverage gate: PASS ({X}%)." Continue.
+- **>= minimum, < target:** Use AskUserQuestion:
+  - "AI-assessed coverage is {X}%. {N} code paths are untested. Target is {target}%."
+  - RECOMMENDATION: Choose A because untested code paths are where production bugs hide.
+  - Options:
+    A) Generate more tests for remaining gaps (recommended)
+    B) Ship anyway — I accept the coverage risk
+    C) These paths don't need tests — mark as intentionally uncovered
+  - If A: Loop back to substep 5 (generate tests) targeting the remaining gaps. After second pass, if still below target, present AskUserQuestion again with updated numbers. Maximum 2 generation passes total.
+  - If B: Continue. Include in PR body: "Coverage gate: {X}% — user accepted risk."
+  - If C: Continue. Include in PR body: "Coverage gate: {X}% — {N} paths intentionally uncovered."
+
+- **< minimum:** Use AskUserQuestion:
+  - "AI-assessed coverage is critically low ({X}%). {N} of {M} code paths have no tests. Minimum threshold is {minimum}%."
+  - RECOMMENDATION: Choose A because less than {minimum}% means more code is untested than tested.
+  - Options:
+    A) Generate tests for remaining gaps (recommended)
+    B) Override — ship with low coverage (I understand the risk)
+  - If A: Loop back to substep 5. Maximum 2 passes. If still below minimum after 2 passes, present the override choice again.
+  - If B: Continue. Include in PR body: "Coverage gate: OVERRIDDEN at {X}%."
+
+**Coverage percentage undetermined:** If the coverage diagram doesn't produce a clear numeric percentage (ambiguous output, parse error), **skip the gate** with: "Coverage gate: could not determine percentage — skipping." Do not default to 0% or block.
+
+**Test-only diffs:** Skip the gate (same as the existing fast-path).
+
+**100% coverage:** "Coverage gate: PASS (100%)." Continue.
+
+### Test Plan Artifact
+
+After producing the coverage diagram, write a test plan artifact so `/qa` and `/qa-only` can consume it:
+
+```bash
+eval "$(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)" && mkdir -p ~/.gstack/projects/$SLUG
+USER=$(whoami)
+DATETIME=$(date +%Y%m%d-%H%M%S)
+```
+
+Write to `~/.gstack/projects/{slug}/{user}-{branch}-ship-test-plan-{datetime}.md`:
+
+```markdown

+# Check opt-out marker
+[ -f .gstack/no-test-bootstrap ] && echo "BOOTSTRAP_DECLINED"
+```
+
+**If test framework detected** (config files or test directories found):
+Print "Test framework detected: {name} ({N} existing tests). Skipping bootstrap."
+Read 2-3 existing test files to learn conventions (naming, imports, assertion style, setup patterns).
+Store conventions as prose context for use in Phase 8e.5 or Step 7. **Skip the rest of bootstrap.**
+
+**If BOOTSTRAP_DECLINED** appears: Print "Test bootstrap previously declined — skipping." **Skip the rest of bootstrap.**
+
+**If NO runtime detected** (no config files found): Use AskUserQuestion:
+"I couldn't detect your project's language. What runtime are you using?"
+Options: A) Node.js/TypeScript B) Ruby/Rails C) Python D) Go E) Rust F) PHP G) Elixir H) This project doesn't need tests.
+If user picks H → write `.gstack/no-test-bootstrap` and continue without tests.
+
+**If runtime detected but no test framework — bootstrap:**
+
+### B2. Research best practices
+
+Use WebSearch to find current best practices for the detected runtime:
+- `"[runtime] best test framework 2025 2026"`
+- `"[framework A] vs [framework B] comparison"`
+
+If WebSearch is unavailable, use this built-in knowledge table:
+
+| Runtime | Primary recommendation | Alternative |
+|---------|----------------------|-------------|
+| Ruby/Rails | minitest + fixtures + capybara | rspec + factory_bot + shoulda-matchers |
+| Node.js | vitest + @testing-library | jest + @testing-library |
+| Next.js | vitest + @testing-library/react + playwright | jest + cypress |
+| Python | pytest + pytest-cov | unittest |
+| Go | stdlib testing + testify | stdlib only |
+| Rust | cargo test (built-in) + mockall | — |
+| PHP | phpunit + mockery | pest |
+| Elixir | ExUnit (built-in) + ex_machina | — |
+
+### B3. Framework selection
+
+Use AskUserQuestion:
+"I detected this is a [Runtime/Framework] project with no test framework. I researched current best practices. Here are the options:
+A) [Primary] — [rationale]. Includes: [packages]. Supports: unit, integration, smoke, e2e
+B) [Alternative] — [rationale]. Includes: [packages]
+C) Skip — don't set up testing right now
+RECOMMENDATION: Choose A because [reason based on project context]"
+
+If user picks C → write `.gstack/no-test-bootstrap`. Tell user: "If you change your mind later, delete `.gstack/no-test-bootstrap` and re-run." Continue without tests.
+
+If multiple runtimes detected (monorepo) → ask which runtime to set up first, with option to do both sequentially.
+
+### B4. Install and configure
+
+1. Install the chosen packages (npm/bun/gem/pip/etc.)
+2. Create minimal config file
+3. Create directory structure (test/, spec/, etc.)
+4. Create one example test matching the project's code to verify setup works
+
+If package installation fails → debug once. If still failing → revert with `git checkout -- package.json package-lock.json` (or equivalent for the runtime). Warn user and continue without tests.
+
+### B4.5. First real tests
+
+Generate 3-5 real tests for existing code:
+
+1. **Find recently changed files:** `git log --since=30.days --name-only --format="" | sort | uniq -c | sort -rn | head -10`
+2. **Prioritize by risk:** Error handlers > business logic with conditionals > API endpoints > pure functions
+3. **For each file:** Write one test that tests real behavior with meaningful assertions. Never `expect(x).toBeDefined()` — test what the code DOES.
+4. Run each test. Passes → keep. Fails → fix once. Still fails → delete silently.
+5. Generate at least 1 test, cap at 5.
+
+Never import secrets, API keys, or credentials in test files. Use environment variables or test fixtures.
+
+### B5. Verify
+
+```bash
+# Run the full test suite to confirm everything works
+{detected test command}
+```
+
+If tests fail → debug once. If still failing → revert all bootstrap changes and warn user.
+
+### B5.5. CI/CD pipeline
+
+```bash
+# Check CI provider
+ls -d .github/ 2>/dev/null && echo "CI:github"
+ls .gitlab-ci.yml .circleci/ bitrise.yml 2>/dev/null
+```
+
+If `.github/` exists (or no CI detected — default to GitHub Actions):
+Create `.github/workflows/test.yml` with:
+- `runs-on: ubuntu-latest`
+- Appropriate setup action for the runtime (setup-node, setup-ruby, setup-python, etc.)
+- The same test command verified in B5
+- Trigger: push + pull_request
+
+If non-GitHub CI detected → skip CI generation with note: "Detected {provider} — CI pipeline generation supports GitHub Actions only. Add test step to your existing pipeline manually."
+
+### B6. Create TESTING.md
+
+First check: If TESTING.md already exists → read it and update/append rather than overwriting. Never destroy existing content.
+
+Write TESTING.md with:
+- Philosophy: "100% test coverage is the key to great vibe coding. Tests let you move fast, trust your instincts, and ship with confidence — without them, vibe coding is just yolo coding. With tests, it's a superpower."
+- Framework name and version
+- How to run tests (the verified command from B5)
+- Test layers: Unit tests (what, where, when), Integration tests, Smoke tests, E2E tests
+- Conventions: file naming, assertion style, setup/teardown patterns
+
+### B7. Update CLAUDE.md
+
+First check: If CLAUDE.md already has a `## Testing` section → skip. Don't duplicate.
+
+Append a `## Testing` section:
+- Run command and test directory
+- Reference to TESTING.md
+- Test expectations:
+  - 100% test coverage is the goal — tests make vibe coding safe
+  - When writing new functions, write a corresponding test
+  - When fixing a bug, write a regression test
+  - When adding error handling, write a test that triggers the error
+  - When adding a conditional (if/else, switch), write tests for BOTH paths
+  - Never commit code that makes existing tests fail
+
+### B8. Commit
+
+```bash
+git status --porcelain
+```
+
+Only commit if there are changes. Stage all bootstrap files (config, test directory, TESTING.md, CLAUDE.md, .github/workflows/test.yml if created):
+`git commit -m "chore: bootstrap test framework ({framework name})"`
+
+---
+
+---
+
+## Step 5: Run tests (on merged code)
+
+**Do NOT run `RAILS_ENV=test bin/rails db:migrate`** — `bin/test-lane` already calls
+`db:test:prepare` internally, which loads the schema into the correct lane database.
+Running bare test migrations without INSTANCE hits an orphan DB and corrupts structure.sql.
+
+Run both test suites in parallel:
+
+```bash
+bin/test-lane 2>&1 | tee /tmp/ship_tests.txt &
+npm run test 2>&1 | tee /tmp/ship_vitest.txt &
+wait
+```
+
+After both complete, read the output files and check pass/fail.
+
+**If any test fails:** Do NOT immediately stop. Apply the Test Failure Ownership Triage:
+
+## Test Failure Ownership Triage
+
+When tests fail, do NOT immediately stop. First, determine ownership:
+
+### Step T1: Classify each failure
+
+For each failing test:
+
+1. **Get the files changed on this branch:**
+   ```bash
+   git diff origin/<base>...HEAD --name-only
+   ```
+
+2. **Classify the failure:**
+   - **In-branch** if: the failing test file itself was modified on this branch, OR the test output references code that was changed on this branch, OR you can trace the failure to a change in the branch diff.
+   - **Likely pre-existing** if: neither the test file nor the code it tests was modified on this branch, AND the failure is unrelated to any branch change you can identify.
+   - **When ambiguous, default to in-branch.** It is safer to stop the developer than to let a broken test ship. Only classify as pre-existing when you are confident.
+
+   This classification is heuristic — use your judgment reading the diff and the test output. You do not have a programmatic dependency graph.
+
+### Step T2: Handle in-branch failures
+
+**STOP.** These are your failures. Show them and do not proceed. The developer must fix their own broken tests before shipping.
+
+### Step T3: Handle pre-existing failures
+
+Check `REPO_MODE` from the preamble output.
+
+**If REPO_MODE is `solo`:**
+
+Use AskUserQuestion:
+
+> These test failures appear pre-existing (not caused by your branch changes):
+>
+> [list each failure with file:line and brief error description]
+>
+> Since this is a solo repo, you're the only one who will fix these.
+>
+> RECOMMENDATION: Choose A — fix now while the context is fresh. Completeness: 9/10.
+> A) Investigate and fix now (human: ~2-4h / CC: ~15min) — Completeness: 10/10
+> B) Add as P0 TODO — fix after this branch lands — Completeness: 7/10
+> C) Skip — I know about this, ship anyway — Completeness: 3/10
+
+**If REPO_MODE is `collaborative` or `unknown`:**
+
+Use AskUserQuestion:
+
+> These test failures appear pre-existing (not caused by your branch changes):
+>
+> [list each failure with file:line and brief error description]
+>
+> This is a collaborative repo — these may be someone else's responsibility.
+>
+> RECOMMENDATION: Choose B — assign it to whoever broke it so the right person fixes it. Completeness: 9/10.
+> A) Investigate and fix now anyway — Completeness: 10/10
+> B) Blame + assign GitHub issue to the author — Completeness: 9/10
+> C) Add as P0 TODO — Completeness: 7/10
+> D) Skip — ship anyway — Completeness: 3/10
+
+### Step T4: Execute the chosen action
+
+**If "Investigate and fix now":**
+- Switch to /investigate mindset: root cause first, then minimal fix.
+- Fix the pre-existing failure.
+- Commit the fix separately from the branch's changes: `git commit -m "fix: pre-existing test failure in <test-file>"`
+- Continue with the workflow.
+
+**If "Add as P0 TODO":**
+- If `TODOS.md` exists, add the entry following the format in `review/TODOS-format.md` (or `.claude/skills/review/TODOS-format.md`).
+- If `TODOS.md` does not exist, create it with the standard header and add the entry.
+- Entry should include: title, the error output, which branch it was noticed on, and priority P0.
+- Continue with the workflow — treat the pre-existing failure as non-blocking.
+
+**If "Blame + assign GitHub issue" (collaborative only):**
+- Find who likely broke it. Check BOTH the test file AND the production code it tests:
+  ```bash
+  # Who last touched the failing test?
+  git log --format="%an (%ae)" -1 -- <failing-test-file>
+  # Who last touched the production code the test covers? (often the actual breaker)
+  git log --format="%an (%ae)" -1 -- <source-file-under-test>
+  ```
+  If these are different people, prefer the production code author — they likely introduced the regression.
+- Create an issue assigned to that person (use the platform detected in Step 0):
+  - **If GitHub:**
+    ```bash
+    gh issue create \
+      --title "Pre-existing test failure: <test-name>" \
+      --body "Found failing on branch <current-branch>. Failure is pre-existing.\n\n**Error:**\n```\n<first 10 lines>\n```\n\n**Last modified by:** <author>\n**Noticed by:** gstack /ship on <date>" \
+      --assignee "<github-username>"
+    ```
+  - **If GitLab:**
+    ```bash
+    glab issue create \
+      -t "Pre-existing test failure: <test-name>" \
+      -d "Found failing on branch <current-branch>. Failure is pre-existing.\n\n**Error:**\n```\n<first 10 lines>\n```\n\n**Last modified by:** <author>\n**Noticed by:** gstack /ship on <date>" \
+      -a "<gitlab-username>"
+    ```
+- If neither CLI is available or `--assignee`/`-a` fails (user not in org, etc.), create the issue without assignee and note who should look at it in the body.
+- Continue with the workflow.
+
+**If "Skip":**
+- Continue with the workflow.
+- Note in output: "Pre-existing test failure skipped: <test-name>"
+
+**After triage:** If any in-branch failures remain unfixed, **STOP**. Do not proceed. If all failures were pre-existing and handled (fixed, TODOed, assigned, or skipped), continue to Step 6.
+
+**If all pass:** Continue silently — just note the counts briefly.
+
+---
+
+## Step 6: Eval Suites (conditional)
+
+Evals are mandatory when prompt-related files change. Skip this step entirely if no prompt files are in the diff.
+
+**1. Check if the diff touches prompt-related files:**
+
+```bash
+git diff origin/<base> --name-only
+```
+
+Match against these patterns (from CLAUDE.md):
+- `app/services/*_prompt_builder.rb`
+- `app/services/*_generation_service.rb`, `*_writer_service.rb`, `*_designer_service.rb`
+- `app/services/*_evaluator.rb`, `*_scorer.rb`, `*_classifier_service.rb`, `*_analyzer.rb`
+- `app/services/concerns/*voice*.rb`, `*writing*.rb`, `*prompt*.rb`, `*token*.rb`
+- `app/services/chat_tools/*.rb`, `app/services/x_thread_tools/*.rb`
+- `config/system_prompts/*.txt`
+- `test/evals/**/*` (eval infrastructure changes affect all suites)
+
+**If no matches:** Print "No prompt-related files changed — skipping evals." and continue to Step 9.
+
+**2. Identify affected eval suites:**
+
+Each eval runner (`test/evals/*_eval_runner.rb`) declares `PROMPT_SOURCE_FILES` listing which source files affect it. Grep these to find which suites match the changed files:
+
+```bash
+grep -l "changed_file_basename" test/evals/*_eval_runner.rb
+```
+
+Map runner → test file: `post_generation_eval_runner.rb` → `post_generation_eval_test.rb`.
+
+**Special cases:**
+- Changes to `test/evals/judges/*.rb`, `test/evals/support/*.rb`, or `test/evals/fixtures/` affect ALL suites that use those judges/support files. Check imports in the eval test files to determine which.
+- Changes to `config/system_prompts/*.txt` — grep eval runners for the prompt filename to find affected suites.
+- If unsure which suites are affected, run ALL suites that could plausibly be impacted. Over-testing is better than missing a regression.
+
+**3. Run affected suites at `EVAL_JUDGE_TIER=full`:**
+
+`/ship` is a pre-merge gate, so always use full tier (Sonnet structural + Opus persona judges).
+
+```bash
+EVAL_JUDGE_TIER=full EVAL_VERBOSE=1 bin/test-lane --eval test/evals/<suite>_eval_test.rb 2>&1 | tee /tmp/ship_evals.txt
+```
+
+If multiple suites need to run, run them sequentially (each needs a test lane). If the first suite fails, stop immediately — don't burn API cost on remaining suites.
+
+**4. Check results:**
+
+- **If any eval fails:** Show the failures, the cost dashboard, and **STOP**. Do not proceed.
+- **If all pass:** Note pass counts and cost. Continue to Step 9.
+
+**5. Save eval output** — include eval results and cost dashboard in the PR body (Step 19).
+
+**Tier reference (for context — /ship always uses `full`):**
+| Tier | When | Speed (cached) | Cost |
+|------|------|----------------|------|
+| `fast` (Haiku) | Dev iteration, smoke tests | ~5s (14x faster) | ~$0.07/run |
