Subject: [PATCH 1/9] v1.91.212.0 fix(careful): mask git commit's own message
 before the MEDIUM checks (#1060, port of #3221) (#3389)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* fix(careful): mask git commit -m content to prevent MEDIUM-tier false positives (#1060)

MEDIUM-tier checks matched the full command string including quoted -m text.
A commit like 'git commit -m fix: prevent drop table in migration' triggered
the SQL DROP warning even though no SQL was being executed.

Build CMD_MEDIUM by stripping -m quoted content from git commit commands
before MEDIUM checks. Real destructive commands outside the quoted string
still match, so true positives are unaffected.

Add tests: commit message patterns do not warn; chained real DROP/TRUNCATE still warns.

* fix(careful): replace sed masking with quote-aware awk scanner (#1060)

The sed-based -m content masker had two bypass paths that capy-ai identified:

  1. Single-quoted message containing a double-quote boundary:
       git commit -m 'note -m "' && rm -rf build && echo '"'
     The double-quote pass matched '-m "' inside the single-quoted string,
     swallowing '&& rm -rf build && echo '; the rm vanished from CMD_MEDIUM.

  2. Double-quoted message with a command substitution:
       git commit -m "$(rm -rf build)"
     sed replaced the content including the $(...), so the substitution
     — which executes in the shell — was masked away.

Replace the sed substitution with a quote-aware awk scanner that:
- Walks the command string tracking single-quote, double-quote, and
  backslash state, so it only treats a delimiter as a message boundary
  when the shell would.
- Masks single-quoted messages (always literal) and double-quoted messages
  that contain no $, backtick, or backslash (safe to mask — no expansion).
- Leaves double-quoted messages with $, backtick, or backslash unmasked
  so command substitutions stay visible to the MEDIUM checks.
- Handles -m, -am, --message, and --message= forms.

Four new tests added as requested (alongside the original six):
- single-quoted message with embedded double-quote + chained rm → warns
- commit message with $(rm -rf build) → warns
- git push --force chained after commit → warns
- git commit -am "drop table notes" → silent (message masked)

* fix(careful): read the commit-message masker from a file, so bash 3.2 can parse the hook (#1060)

* fix(careful): scan the command as one string, so a newline still separates commands from the message (#1060)

* fix(careful): mask only git commit's own message; a piped commit or another command's -m stays visible (#1060)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix(careful): a pipe, process substitution or parameter expansion after the message unmasks it; redirections and comments parse like bash (#1060)

 # Changelog
 
+## [1.91.212.0] - 2026-10-25
+
+**/careful no longer asks about words inside a commit message (#1060; ported from #3221 by @Bhumika-1432006).** The careful hook matched its MEDIUM patterns against the whole command, so `git commit -m "fix: prevent drop table in migration"` asked for approval as an SQL DROP. The hook now masks git commit's own literal message before those checks, including the `-m "$(cat <<'EOF' … EOF
+)"` form agents use most. Our commits on top of the contributor's scanner fix four problems found in review: the inline awk program made the whole hook a bash syntax error on bash 3.2 (macOS `/bin/bash`), so every Bash call failed the hook there; a newline after the message was dropped, so `-m x⏎truncate …` stopped asking; any `-m '…'` after a commit was masked, including another command's argument; and the heredoc form was never masked.
+
+### Fixed
+- **`careful/bin/mask-commit-message.awk`** (new, from the contributor's scanner): reads the command as one string and keeps its newlines. It splits at unquoted `;` `&` `|` `(` `)` and newlines (a redirection's `&` does not split) and masks `-m`, `-am`, `--message` and `--message=` only in a segment whose first word is `git` with a `commit` word after it. Single-quoted messages, double-quoted messages without `$`, backtick or backslash, and a double-quoted `$(cat <<'DELIM' … DELIM )` with a quoted delimiter are masked. Quotes, backslashes and comments are parsed as bash does. The command is left unmasked when it contains any other command, parameter or process substitution, a backtick, `$'…'`, a heredoc, an unterminated quote, or a pipe after a masked message (git prints the message on stdout).
+- **`careful/bin/check-careful.sh`**: runs the program with `awk -f` from the hook's own directory, so bash 3.2 parses the hook again. A missing program or an awk error leaves the command unmasked. The HIGH deny tier, the PowerShell table and the obfuscation tripwire still read the unmasked command.
+
+### Tests
+- `test/hook-scripts.test.ts` keeps the contributor's 10 cases and adds 31. Masked (no prompt): every flag form, `git -C repo commit`, `--amend`, multi-line messages and four heredoc spellings (`'EOF'`, `"MSG"`, `<<-` with a tab, a quoted word in the body). Still asking: a command on the next line, a quote that spans a line break, another command's `-m`, `echo git commit -m '…'`, an escaped quote, a backslash-newline, a heredoc with an unquoted delimiter, a substitution that closes the message early, a backtick, `git commit -F - <<'EOF'`, `$'…'`, a pipe after the commit (direct, after `2>&1`, or from a subshell), a process substitution and a parameter expansion. A partial install without the awk file still asks.
+- The same cases pass with mawk and the one-true-awk (`original-awk`, the awk macOS ships). In a `bash:3.2` container the hook as submitted in #3221 exits 2 with `unexpected EOF while looking for matching '"'` on every command; with this change it answers normally.
+
+### Gate integrity
+- One accepted-input change to review, in a safety hook: MEDIUM checks (and custom `careful-patterns.txt` rules) no longer see the masked text of git commit's own literal message. That is a weakening by design, limited to text that bash passes to git as a literal argument. The negative controls listed under Tests still ask. Commands that combine a commit with anything that could execute the message, or that the scanner cannot read with certainty, are checked unmasked, exactly as on main. No threshold, budget, timeout, trial count or case kind changed.
+- Known limit, still a false positive as on main: `git commit -F - <<'EOF'` messages and commits after an environment assignment or `sudo` are not masked.
+
 ## [1.91.211.0] - 2026-10-25
 
 **`gstack-diff-scope` sees Python tests and nested test directories (#3335).** A branch that changed `components/orch/services/shared/tests/test_native_store_custody.py` reported `SCOPE_TESTS=false`, because the Tests rule only knew `*.test.*`-style suffixes and `test/`, `tests/`, `spec/` and `__tests__/` at the repository root. /ship and /review use that flag to route the testing specialist, so a backend change whose tests follow pytest's `test_*.py` convention skipped it. The test-bootstrap resolver already counted these files, so the two detectors disagreed.

Subject: [PATCH 2/9] v1.91.213.0 fix(ci): Node.js 22.23.4 in the CI image and
 Ubicloud free-suite VMs, SHA-256 verified (port #3355, fixes #3354) (#3400)

* fix(ci): bump Node.js to 22.23.4 for CVE-2026-111497

* fix(ci): pin Node.js 22.23.4 in the Ubicloud free-suite bootstrap too, and verify both archives by SHA-256

#3355 bumped Dockerfile.ci only; scripts/ubicloud/setup-free-suite.sh still
installed 22.20.0. Both now pin the same version and the linux-x64 SHA-256
from the release's signed SHASUMS256.txt, check the archive before unpacking,
and test/ci-image-cli-pin.test.ts keeps the two pins equal (#3354).

* docs(changelog): Node.js 22.23.4 CI pin (#3354)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* test(ci-image): name Dockerfile.ci in a form pregate resolves; assert the image hash in the parity case

 # Changelog
 
+## [1.91.213.0] - 2026-10-25
+
+**The CI image and the Ubicloud free-suite VMs move off Node.js 22.20.0 to 22.23.4, and both now check the Node archive's SHA-256 before unpacking it (#3354, port of #3355 by @michael-sumner).** 22.20.0 is affected by the October 21, 2026 Node.js security releases, including the Brotli decoder out-of-bounds write (CVE-2026-111497, high) and the TLS hostname bypass for leading-zero IPv4 hosts (CVE-2026-106069, high). 22.23.4 is the patched 22.x release. #3355 bumped `.github/docker/Dockerfile.ci`, but `scripts/ubicloud/setup-free-suite.sh` pins Node separately and would have kept installing 22.20.0 on every remote free-suite run.
+
+### Fixed
+- **`.github/docker/Dockerfile.ci`**: `NODE_VERSION` is 22.23.4 (Michael Sumner's commit). The archive is checked against `NODE_SHA256`, the linux-x64 hash from the release's SHASUMS256.txt, whose signature verifies against the Node.js release keyring, before it is unpacked.
+- **`scripts/ubicloud/setup-free-suite.sh`**: pins the same 22.23.4 and hash, and downloads the archive to a temporary file and verifies it instead of piping `curl` straight into `sudo tar`.
+
+### Tests
+- `test/ci-image-cli-pin.test.ts` gains four cases: Dockerfile.ci pins an exact Node version and a SHA-256, both files verify before they unpack, and `setup-free-suite.sh` pins the same version and hash as the image. On #3355's head alone, all four fail; on main, three fail.
+- The Bun ordering check in `setup-free-suite.sh` now looks for `sha256sum -c` after the Bun download instead of anywhere in the file, because the Node check now comes first.
+- The test names `Dockerfile.ci` as `join(__dirname, '..', '.github', …)`, the form pregate's literal scan resolves, so a change to the image now selects it (before, pregate refused a Dockerfile.ci-only change with `PREGATE_NO_LANE`).
+
+### Gate integrity
+- One accepted-input change to review: the Bun ordering check searches for its `sha256sum -c` from the Bun download onward. It now accepts one input it used to reject: a file with some other `sha256sum -c` before the Bun download and the Bun check after it, which is this file. The property it guards, Bun verified after download and before unpack, is unchanged. A file whose only `sha256sum -c` sits before the download still fails, and so does removing the Bun hash or moving it after `unzip` (negative controls run). No threshold, budget, timeout, trial count or case kind changed.
+
 ## [1.91.212.0] - 2026-10-25
 
 **/careful no longer asks about words inside a commit message (#1060; ported from #3221 by @Bhumika-1432006).** The careful hook matched its MEDIUM patterns against the whole command, so `git commit -m "fix: prevent drop table in migration"` asked for approval as an SQL DROP. The hook now masks git commit's own literal message before those checks, including the `-m "$(cat <<'EOF' … EOF

+## [1.91.214.0] - 2026-10-25
+
+**`gstack-brain-sync --publish-removals --yes` no longer prints `list: unbound variable` when it finishes, and it now removes its temp list and releases the sync lock.** The command's EXIT trap named the function's local `$list`. When a publish succeeded, the function returned before the script exited, so the trap ran after `list` had gone out of scope. Under `set -u` it stopped at the unbound variable and never reached the cleanup, which left `brain-sync-removals.*` in `$TMPDIR` and `.brain-sync.lock.d` in `~/.gstack` until a later run cleared the lock as stale (found by GSTA-44).
+
+### Fixed
+- **`bin/gstack-brain-sync`**: `--publish-removals` writes the temp file paths into its EXIT/INT/TERM trap when it installs the trap (quoted with `printf %q`), so the cleanup and lock release work however the function ends. The drain's trap in `--once` also names locals, but every path in that function ends with `exit` while they are still in scope, so it's unchanged. The other trap sites (the drain's lock-only trap and `gstack-brain-restore`'s, which uses a global) don't have the bug.
+
+### Tests
+- `test/brain-sync-removals.test.ts`: a new case runs `--publish-removals`, then `--publish-removals --yes` twice (publishing, then nothing to publish) with a private `TMPDIR`. After each run, stderr has no `unbound variable`, the exit status is 0, `TMPDIR` is empty and the lock directory is gone. It failed before the fix.

 ## [1.91.213.0] - 2026-10-25
 
 **The CI image and the Ubicloud free-suite VMs move off Node.js 22.20.0 to 22.23.4, and both now check the Node archive's SHA-256 before unpacking it (#3354, port of #3355 by @michael-sumner).** 22.20.0 is affected by the October 21, 2026 Node.js security releases, including the Brotli decoder out-of-bounds write (CVE-2026-111497, high) and the TLS hostname bypass for leading-zero IPv4 hosts (CVE-2026-106069, high). 22.23.4 is the patched 22.x release. #3355 bumped `.github/docker/Dockerfile.ci`, but `scripts/ubicloud/setup-free-suite.sh` pins Node separately and would have kept installing 22.20.0 on every remote free-suite run.

Subject: [PATCH 4/9] fix(ship): unattended handoff writes the receipt to a
 file the parent reads (GSTA-88) (#3409)

Step 18-H's receipt write gains --out .gstack/tmp/ship-receipt.md; skill-start
prints a ship-only UNATTENDED_SHIP line; docs/unattended.md sends the parent to
read --body on that file and to compare head to the branch SHA.

 # Changelog
 
+## [1.91.215.0] - 2026-10-25
+
+**An unattended `/ship` leaves its receipt in a file the parent can read, and the parent is told to read that file (GSTA-88).** Before, Step 18's handoff section wrote the ship receipt only to stdout, and `docs/unattended.md` told the parent to read it from the PR body with `gstack-ship-receipt read --pr <n> --json`. An unattended run must not push, so there is no PR: the parent got a usage error or `RECEIPT_MISSING`, or, if an older PR existed, read that PR's receipt with exit 0 and a stale `head`. Now the handoff writes `.gstack/tmp/ship-receipt.md`, the parent reads it with `read --body` in the child's checkout, and it compares the receipt's `head` to the branch SHA either way.
+
+### Fixed
+- **`ship/sections/handoff.md.tmpl`**: the receipt write carries `--out .gstack/tmp/ship-receipt.md`. The completion-message step drops `(\`pr: none\`)`, which was wrong (the block omits `pr`; only the `SHIP_RECEIPT:` line shows `pr=-`), and the "nothing precedes the identifiers" clause, which repeated "identifiers first". Ship's skeleton plus sections is 313,151 bytes, 13 below main and under its 313,281 cap; no cap or pin moved.
+- **`bin/gstack-skill-start`**: an unattended `/ship` prints one status line, `UNATTENDED_SHIP: no push, no PR; Step 18 takes the handoff section; receipt at .gstack/tmp/ship-receipt.md`. No other skill or session kind prints it, and no instruction block was added. The unattended block's `/ship` record sentence names the file for a run that did not push and the PR body only once a PR exists.
+- **`docs/unattended.md`**: for `/ship`, read `gstack-ship-receipt read --body .gstack/tmp/ship-receipt.md --json` in the child's checkout when the run did not push, use `read --pr <n> --json` only once a PR exists, and in both cases compare the receipt's `head` to the branch SHA, because `read` does not check that the receipt is current.
+
+### Tests
+- `test/gstack-ship-receipt.test.ts` runs the handoff template's write command as written in a fixture repository, then reads the file back with `read --body`: `head` is HEAD, `session_kind` is `unattended` and there is no `pr`. It also checks that the template and the generated section carry `--out` and that `docs/unattended.md` names the same file with `read --body`.
+- `test/gstack-skill-start.test.ts` checks that the `UNATTENDED_SHIP` line appears exactly once for an unattended `/ship`, alongside only the `unattended-session` block, and never for `/review`, `/qa`, `/autoplan` or for `/ship` in an interactive, spawned or headless session.

 # Changelog
 
+## [1.91.216.0] - 2026-10-25
+
+**/sync-gbrain refuses an active autopilot before it touches the brain's source list (#3360, part 2; ported from #3362 by @exGeni).** The code stage checked for a running `gbrain autopilot` only right before its destructive walk. By then it had already cleaned up legacy sources, renamed a source and run `gbrain sources add`, so a refused run still registered a source it never synced.
+
+### Fixed
+- **`bin/gstack-gbrain-sync.ts`**: the code stage runs the autopilot check before Step 0a, so a refusal leaves the source list untouched. The check before the walk stays, because autopilot can start while the steps in between run. Dry-run, read-only and deny policies and the local-engine skip still return earlier and are unchanged. Which processes count as an autopilot (the machine-wide probe, #3360 part 1) is unchanged.
+
+### Tests
+- `test/gstack-gbrain-sync.test.ts` runs the real script against a fake `gbrain` and a `pgrep` that reports an autopilot: the stage is refused and the fake saw no `sources add`, `rename`, `remove` or `sync`. On main the same run issues `sources add`.
+
 ## [1.91.215.0] - 2026-10-25
 
 **An unattended `/ship` leaves its receipt in a file the parent can read, and the parent is told to read that file (GSTA-88).** Before, Step 18's handoff section wrote the ship receipt only to stdout, and `docs/unattended.md` told the parent to read it from the PR body with `gstack-ship-receipt read --pr <n> --json`. An unattended run must not push, so there is no PR: the parent got a usage error or `RECEIPT_MISSING`, or, if an older PR existed, read that PR's receipt with exit 0 and a stale `head`. Now the handoff writes `.gstack/tmp/ship-receipt.md`, the parent reads it with `read --body` in the child's checkout, and it compares the receipt's `head` to the branch SHA either way.

+## [1.91.217.0] - 2026-10-25
+
+**Windows free tests now also run on every push to main.** `windows-free-tests.yml` ran on pull requests and dispatch only: 194 PR runs, 6 dispatches and 0 pushes in its last 200 runs. Merge trains dispatch only `free-tests.yml` on the train branch. So no Windows run ever saw a train's combined tree or main after a merge, and a Windows break caused by two individually green PRs only surfaced on the next unrelated PR. Found while working on GSTA-68.
+
+### Fixed
+- **`.github/workflows/windows-free-tests.yml`**: adds `push: branches: [main]`, the same trigger free-tests.yml already has. The run uses the existing per-run concurrency group, and `record_durations` stays dispatch-only (on a push, `inputs.record_durations` is empty, so the lane runs and the recorder skips). Cost: about 40 job-minutes on GitHub's free `windows-latest` runners per merge.
+
+### Tests
+- `test/windows-native-workflows.test.ts` pins the new trigger set and requires the push trigger to be limited to main.

Subject: [PATCH 7/9] fix(team-init): register the required Skill hook with
 onFailure: block (#3319) (#3393)

Without node on PATH the node -e launcher exits 127, and with check-gstack.cjs
missing it exits 1; Claude Code treats both as non-blocking and lets the Skill
call through. Register the handler with onFailure: block (Claude Code 2.1.295+),
upgrade existing registrations in place, and tell the agent and the developer
what the two block reasons mean.

 # Changelog
 
+## [1.91.218.0] - 2026-10-25
+
+**`gstack-team-init required` now blocks skills when its gate can't run, instead of letting them through.** Issue #3319 (exGeni): the required-mode Skill hook is a `node -e` launcher. On a teammate's Mac or Linux machine without Node.js, the shell exits 127 with nothing on stdout. If `.claude/hooks/check-gstack.cjs` is missing, node exits 1. Claude Code treats any exit other than 0 or 2 as a non-blocking error, so in both cases the Skill call went ahead on exactly the machine the gate is for. A live Claude Code 2.1.310 session with node off PATH and no gstack install ran the skill.
+
+### Fixed
+- **`bin/gstack-team-init`**: the check-gstack handler is registered with `"onFailure": "block"`, Claude Code's documented fail-closed switch (2.1.295+). A launcher that can't start, or exits with any code other than 0 or 2, now blocks the Skill call. The reason shown is `blocking because onFailure is "block"` plus the shell's `node: not found` (or node's `Cannot find module …check-gstack.cjs`). Exit 2 (deny) and exit 0 (allow) are unchanged. Re-running `required` upgrades an existing registration in place, and the manual-registration fallback names the field.
+- The required CLAUDE.md section tells the agent what those two block reasons mean (install Node.js; the hook file is missing) and not to work around them. `required` prints that every developer needs node on PATH and Claude Code 2.1.295+, and the README says the same.
+
+### Compatibility
+- Measured with a live `claude -p` Skill call per version. 2.1.295 and 2.1.310 block when node is missing or the hook file is gone, still deny with exit 2 when gstack is absent, and still run the skill when gstack is installed. 2.1.294 ignores the unknown field without rejecting the settings file: the hook still loads and denies as before, and a machine without node is still let through there, as it was before this change.
+- Copilot CLI documents command `preToolUse` hooks as already failing closed on a crash or non-zero exit, so this change does not alter its outcome. Its handling of the extra field was not measured (no Copilot login on the test machine).
+
+### Tests
+- `test/gstack-team-init-hook-schema.test.ts`: the handler is `{ type, command, onFailure: 'block' }`. The registered command exits 127 with no stdout when node is off PATH and 1 when check-gstack.cjs is missing, the failures only `onFailure` turns into a block. Re-running upgrades a handler registered without the field to exactly one handler with it.
+- `test/team-init-hook-shell-neutral.test.ts`: through the platform's default shell, the command without node exits neither 0 nor 2 with empty stdout, and the bin registers the handler with `onFailure: 'block'`. The PowerShell case and its retries are unchanged.
+- `test/team-mode.test.ts`: the legacy-upgrade assertion pins the new field.
+
+### Gate integrity
+- One gate edit, and it tightens the gate: the required-mode Skill hook goes from fail-open to fail-closed when its launcher fails. Nothing that used to block now allows. Negative controls: with `onFailure` removed from the bin, 4 tests fail (the three new registration and upgrade tests plus the team-mode pin); with it dropped only from the in-place upgrade path, 2 fail. The live runs with gstack installed (2.1.294, 2.1.310) still run the skill, so the allow path is not broken. No threshold, budget, timeout, retry or trial count changed.

 **Windows free tests now also run on every push to main.** `windows-free-tests.yml` ran on pull requests and dispatch only: 194 PR runs, 6 dispatches and 0 pushes in its last 200 runs. Merge trains dispatch only `free-tests.yml` on the train branch. So no Windows run ever saw a train's combined tree or main after a merge, and a Windows break caused by two individually green PRs only surfaced on the next unrelated PR. Found while working on GSTA-68.

 # Changelog
 
+## [1.91.219.0] - 2026-10-25
+
+**Local paid runs from `eval:bg` now set `EVALS_RUN_ID`, so the native-capture cases start instead of failing in 0 seconds.** CI sets `EVALS_RUN_ID` per slice, but `bun run eval:bg:pr --local` launched without it, and the qa-callers, ship-docsync and qa-functional cases refuse to start without it. In GSTA-70's local /ship run, 17 of the 26 selected behaviors failed that way for $0. A failure like that is a launch failure, not a verdict, so the local run told you nothing about those cases.
+
+### Fixed
+- **`scripts/eval-bg.ts`**: the local backend launches through a new `launchLocal`. It exports `EVALS_RUN_ID` as the run-scoped log's name, reduced to `[A-Za-z0-9_.-]`, and keeps a value you exported yourself. The id is written on the log's second line, so you can find the run's native captures. `--help` says so. Dispatched CI runs are unchanged.
+
+### Tests
+- `test/eval-detach-timeout-floor.test.ts`: a detached child launched by `launchLocal` sees a safe `EVALS_RUN_ID` named after its log, and an exported id is kept. A source check confirms that the local backend launches through `launchLocal`.
+
 ## [1.91.218.0] - 2026-10-25
 
 **`gstack-team-init required` now blocks skills when its gate can't run, instead of letting them through.** Issue #3319 (exGeni): the required-mode Skill hook is a `node -e` launcher. On a teammate's Mac or Linux machine without Node.js, the shell exits 127 with nothing on stdout. If `.claude/hooks/check-gstack.cjs` is missing, node exits 1. Claude Code treats any exit other than 0 or 2 as a non-blocking error, so in both cases the Skill call went ahead on exactly the machine the gate is for. A live Claude Code 2.1.310 session with node off PATH and no gstack install ran the skill.

 # Changelog
 
+## [1.91.220.0] - 2026-10-25
+
+**A design doc edited in host plan mode no longer goes stale for the plan reviews (#542).** When /office-hours ran inside Claude Code's plan mode, the design doc lived twice: gstack's copy under `~/.gstack/projects/<slug>/` and the host's plan file under `.claude/plans/`. Later edits went only to the plan file, so /plan-ceo-review and /plan-eng-review read the older gstack copy and called it the source of truth. The gstack design doc stays the single source (Garry, Oct 17: "designdoc"). Edits made in the plan copy are now written through to it, and every plan review is warned when the copy is newer.
+
+### Fixed
+- **`office-hours/SKILL.md.tmpl`**: the closing design-doc check takes the host plan file that holds the doc. When that file is newer and differs, it is copied over the gstack doc (`PLAN_COPY: written through`), and the pairing is recorded beside the doc in `<doc>.plan-copy`. A repo copy under `docs/designs/` is rewritten from the doc under Phase 5's scan rule. An older plan file never overwrites the doc, and outside plan mode nothing is recorded.
+- **`bin/gstack-design-doc-find`**: when the newest state-root doc has a recorded plan copy, the helper prints `DESIGN_PLAN_COPY` with the write-through command on stderr. When the copy is newer than the chosen doc and differs from it, it also prints `STALE_DESIGN_DOC` with the `cp` to run before reading. Stdout still prints only the doc path, so every caller of `{{DESIGN_DOC_DISCOVERY}}` (plan reviews, /autoplan, the spec-review prerequisite check) gets the lines with no change in rendered size. The write-through always targets the state-root doc, even when a newer repo copy won discovery.
+- **`plan-ceo-review/SKILL.md.tmpl`, `plan-eng-review/SKILL.md.tmpl`**: the design-doc check runs a `STALE_DESIGN_DOC` write-through before reading and says so in one line. After a review edits the plan copy, it runs the `DESIGN_PLAN_COPY` write-through after the exit gate, before telemetry.
+- To stay within the SKILL.md size pins, plan-eng-review drops its 15th cognitive pattern ("Error budgets", already named in pattern 7), and office-hours drops three explanatory sentences (cross-team discovery, the profile binary's mktemp details, the `sessions[]` array) and shortens one.
+
+### Tests
+- `test/design-doc-plan-copy.test.ts` runs the real helper and the generated office-hours block against temp state roots: no recorded copy (silent), a copy in sync (named, no warning), a newer edited copy (warning; running its printed `cp` updates the doc and clears it), a doc edited after the copy (no warning), relative, non-markdown and missing recorded paths (ignored), and a repo copy that wins discovery (the write-through still targets the state-root doc). The office-hours block writes newer plan edits through, never lets an older plan file overwrite the doc, and records nothing outside plan mode. Both plan reviews carry the helper's two line names.
+
+### Gate integrity
+- Size pins in `test/fixtures/skill-md-size-allowlist.json` only go down: plan-eng-review by 44 characters on 11 hosts, office-hours by 31 on 4 hosts. No pin was raised. No threshold, budget, timeout, trial count or case kind changed.
+
 ## [1.91.219.0] - 2026-10-25
 
 **Local paid runs from `eval:bg` now set `EVALS_RUN_ID`, so the native-capture cases start instead of failing in 0 seconds.** CI sets `EVALS_RUN_ID` per slice, but `bun run eval:bg:pr --local` launched without it, and the qa-callers, ship-docsync and qa-functional cases refuse to start without it. In GSTA-70's local /ship run, 17 of the 26 selected behaviors failed that way for $0. A failure like that is a launch failure, not a verdict, so the local run told you nothing about those cases.
