 **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.
 
@@ -13,6 +13,122 @@
 - `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.
 
+## [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.
+
+### 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 "$(cat <<'EOF' … EOF
+)"` form agents use most. Our commits on top of the contributor's scanner fix four problems found in review: the inline awk program made the whole hook a bash syntax error on bash 3.2 (macOS `/bin/bash`), so every Bash call failed the hook there; a newline after the message was dropped, so `-m x⏎truncate …` stopped asking; any `-m '…'` after a commit was masked, including another command's argument; and the heredoc form was never masked.
+
+### Fixed
+- **`careful/bin/mask-commit-message.awk`** (new, from the contributor's scanner): reads the command as one string and keeps its newlines. It splits at unquoted `;` `&` `|` `(` `)` and newlines (a redirection's `&` does not split) and masks `-m`, `-am`, `--message` and `--message=` only in a segment whose first word is `git` with a `commit` word after it. Single-quoted messages, double-quoted messages without `$`, 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.
+
+### Fixed
+- **`bin/gstack-diff-scope`**: a changed path is a test when it matches `TEST_PATH_RE`, the same regex the test-bootstrap resolver uses for its TESTFILES count (`scripts/resolvers/testing.ts`): test dirs at any depth, `test_*.py`, `tests.py`, `_test.<ext>`, `.test.`/`.spec.` JS and TS, `_spec.rb` and `*Test.java`/`.kt`. `conftest.py` counts too. The existing globs stay.
+
+### Tests
+- `test/diff-scope.test.ts` adds the issue's three paths, `pkg/test_store.py`, Django's `tests.py`, `conftest.py`, and nested `__tests__/` and `spec/` dirs; all eight fail on main. Controls that stay `SCOPE_TESTS=false`: `latest.py`, `contest_rules.py`, `attest_signer.py` and a `testing/` dir. A new test checks that `TEST_PATH_RE` is byte-identical to the resolver's regex, so the two can't drift again.
+
+## [1.91.210.0] - 2026-10-25
+
+**/autoplan works when Claude Code's project directory is a subfolder of the repository (#3296).** When the git root sits above the project (for example the root is `$HOME` and the session starts in `$HOME/projects/app`), a worktree session's journal lives in `.claude/worktrees/<name>` under that subfolder. The publication guard only looked for `<project dir>/.git/worktrees`, found nothing, and denied every phase Read with `foreign_cwd`, so the reporter had to restart the session from the repository root.
+
+### Fixed
+- **`autoplan/bin/phase-publication-hook.ts`**: `linkedWorktrees` walks up from the project directory to the first `.git` and reads that repository's worktree registry. A `.git` file (the project is itself a linked worktree or a submodule) stops the walk with no owners, as before. Git's two-way link is still required: the registry entry must name the worktree's `.git` file and that file must name the same entry back. No `git` process is started inside the hook.
+
+### Tests
+- `test/autoplan-publication-hook.test.ts` builds the reporter's layout with real `git worktree add`: a subfolder project directory (and a deeper one) owns the worktree under it, and the root still does. It fails on main. Controls that still get no owners: a nested independent repository (its own `.git` stops the walk), a project directory inside a linked worktree, a registry entry whose worktree names another repository, and a directory with no `.git` above it.
+
+### Gate integrity
+- One accepted-input change to review: from a project directory below the repository root, the guard now accepts the journal of a linked worktree of that same repository, which it already accepted when the project directory was the root. The seven existing `foreign_cwd` refusals in `test/autoplan-publication-guard.test.ts` (no link, one-sided links, another repository, a submodule gitdir, a project that is itself a worktree, a bare repository) still deny. No threshold, budget, timeout, trial count or case kind changed.
+
+## [1.91.209.0] - 2026-10-25
+
+**The free test suite no longer rewrites a contributor's global git pre-push hook (#3353).** On a machine with a global `core.hooksPath`, `test/redact-prepush-target.test.ts` and `test/fs-utils.test.ts` ran `gstack-redact install-prepush-hook` with the parent environment. Git resolved the hooks directory to the global one, so the install moved the developer's own `pre-push` to `pre-push.local` and left a managed wrapper pointing into the test checkout, which breaks every later push once that checkout is gone. The same config also failed 4 tests in the target file, 5 in `test/redact-prepush-hook.test.ts` and 1 in `fs-utils`. CI has no global hooks path, so it stayed green.
+
+### Fixed
+- **`test/helpers/git-env.ts`** (new): `gitEnv()` is the one fixture environment for git and hook installs: `GIT_CONFIG_GLOBAL=/dev/null`, `GIT_CONFIG_NOSYSTEM=1`, `GIT_CONFIG_COUNT=0` and no `GIT_CONFIG_PARAMETERS`. Config written inside the fixture repo still applies.
+- `test/redact-prepush-target.test.ts`, `test/redact-prepush-hook.test.ts` and `test/fs-utils.test.ts` pass it to every fixture git, install and hook spawn. `test/redact-prepush-scan-range.test.ts` and `test/redact-prepush-rebase-force-push.test.ts` drop their private copies (#2967) and import it.
+
+### Tests
+- A new case in `test/redact-prepush-target.test.ts` sets a global, system and environment `core.hooksPath` to a hook that fails, builds the fixture, and checks the developer's hooks directory is untouched, the managed hook landed in the fixture repo, and a push never runs the developer's hook. It fails without the shared environment.
+- Rerun of the issue's repro with `HOME` pointing at a gitconfig with a global hooks dir: on main, two files rewrote it and three files had failures; with this change all six `redact-prepush-*` and `fs-utils` files pass and the directory is unchanged.
+
+## [1.91.208.0] - 2026-10-25
+
+**The Capy install guide says that the team-mode session-start updater also waits for live workflow leases.** With #3385 (#3363), `bin/gstack-session-update` skips its background fast-forward while another session holds a live workflow lease, the same leases `bin/gstack-upgrade` already honors. `docs/capy-install.md` described only the upgrade side.
+
+### Documentation
+- **`docs/capy-install.md`**: the workflow-lease paragraph now says the team-mode SessionStart hook (`bin/gstack-session-update`) honors the same leases. It logs `SKIP leased pid=<p>/<age>m` to `analytics/session-update.log` and tries again at the next session start, without writing its hourly throttle stamp.
+
+## [1.91.207.0] - 2026-10-25
+
+**Per-repository session counts include sessions from removed Claude Code worktrees (ported from #3334 by @Shweta-Mishra-ai).** Claude Code creates worktrees at `<repo>/.claude/worktrees/<name>` and removes them once their branch merges, but their session history stays. `gstack-global-discover` resolved each session's recorded directory with git, so a removed worktree resolved to nothing: its sessions counted in the tool total and in no repository. Reproduced on main: 2 sessions in a repo plus 3 in a removed worktree gave `total_sessions 5` but 2 for the repo.
+
+### Fixed
+- **`bin/gstack-global-discover.ts`**: when a session's directory no longer exists and sits inside `<repo>/.claude/worktrees/<name>` (or a subdirectory of it), the session counts with `<repo>`. Any other missing directory, and a worktree whose repository is gone too, still count in no repository. A live worktree keeps its own path, as before.
+
+### Tests
+- `test/global-discover.test.ts` gains six end-to-end cases built with real `git worktree add` and `remove` (removed worktree, a subdirectory of one, a repo with no remote, plus the live-worktree, gone-repo and plain-missing-directory controls) and table tests for the path matcher. The three positive cases and the matcher tests fail on main.
+
+## [1.91.206.0] - 2026-10-25
+
+**A repo that keeps `.gstack/` out of git can give pregate a policy, and name the CI lanes a local run satisfies (#3286).** On a shared repo where gstack is one contributor's tool, pregate fell back to defaults, so every platform lane the machine could not run (an `ubuntu-latest` suite on a Mac, say) became a `requires-remote` obligation that never cleared, even when that suite runs the same here. Ported from #3286 by arlophoenix, whose 13 commits carry the feature (merged with their history kept); our commits on top close two findings from a security-focused review of the port.
+
+### Added
+- **`lib/pregate/context.ts`, `lib/pregate/config.ts`** (arlophoenix): when the base branch carries no `.gstack/pregate.json`, `gstack-pregate run` reads `<state root>/projects/<slug>/pregate.json`. Never under `--policy-from head`, never a relative path or one inside the checkout, and never chosen by a checkout's `.env` (the bin ignores it, and a bare `bun gstack-pregate` beside one refuses). An unreadable file, a dangling link on its path, `sealed` or `price_file` refuses with `PREGATE_CONFIG_INVALID`; a base copy git cannot read refuses with `POLICY_SOURCE_UNAVAILABLE` unless `git ls-tree` confirms it is absent.
+- **`local`** (arlophoenix): `<workflow.yml>/<job>` lanes a local run satisfies run here instead of becoming `requires-remote`. Under 8 cores with a `remote_gate` or remote `test_backend`, the small-machine obligation still stands.
+- **`lib/pregate/index.ts`** (arlophoenix): the record names the user file and its digest, and `verify` goes `PREGATE_STALE` when it is edited, deleted, or appears after a run under the defaults. Fix texts for missing lanes, strays, stalls and `remote_gate` name the active policy file.
+
+### Fixed
+- **`lib/pregate/context.ts`**: a user policy whose path reaches the checkout through any symlink is ignored. Before, only the lexical path and the final target were checked, so a state root linked into the checkout, holding a link back out to another existing policy, let a branch choose a more permissive file without changing its bytes.
+- **`lib/pregate/index.ts`**: `verify` goes `PREGATE_STALE` when a link on the way to the absent user path starts pointing nowhere. A fresh run refuses that state, but verify looked only at the leaf, so an old defaults pass stayed publishable. The loader and verify now share one absence check.
+
+### Tests
+- `test/pregate-user-policy.test.ts` (new, arlophoenix) covers the user file, `local`, the refusals, `.env` isolation and stale receipts. New cases: a link chain through the checkout is refused for both a linked state root and a single in-repo hop, while a direct outside link is still read; and verify goes stale on a dangling parent, with the plain-absent path as the control.
+- `test/pregate-rust.test.ts`: the two cargo-lane cases skipped on Windows carry a `TODO(#3380)` naming the gap.
+
+### Gate integrity
+- No threshold, budget, timeout, trial count, case kind or skip changed. The user file can relax lanes only where the base has no policy at all, and only from outside the repository; the two fixes make that containment stricter.
+- No new dependency, no network call, no workflow change.
+

 **/ship's Step 9 can re-review just the fixes after a fixing pass, and a narrowed pass can never be the review that ships (#3339).** Before, every fix cycle reran every specialist and the Red Team over the whole branch. On a large branch each full pass tends to find something new in code earlier passes already read, so the loop often ran to the three-cycle stop without converging. Now the pass after a fixing pass can review only what changed since that pass. One full pass still has to come last: a fix-range record is never CURRENT, and Step 11.5 can't bind it. Garry approved this on 2026-10-24 ("only with a mandatory final full pass").
