3bf43766d5 v1.38.0.0 fix wave: Windows install hardening + Unicode sanitization at server egress (4 community PRs) (#1505) 
* fix(browse): single-point Unicode sanitization at server egress

Add sanitizeLoneSurrogates (regex-based UTF-16 lone-half cleaner) and
sanitizeReplacer (JSON.stringify replacer that runs the cleaner on every
string field during encoding).

Split handleCommandInternal into handleCommandInternalImpl (raw) plus a
thin sanitizing wrapper. The wrapper applies sanitizeLoneSurrogates to
cr.result so both single-command (handleCommand line 1034) and batch-loop
(line 1966) egress paths inherit it. Inline INVARIANT comment near the
wrapper documents the architectural constraint.

Both SSE producers (activity feed at /activity/stream and inspector
stream) stringify with sanitizeReplacer. Post-stringify regex is
ineffective on those paths because JSON.stringify has already converted
the lone surrogate into the escape sequence "\\\\uD800" before any regex
could match it; the replacer runs during stringify on the raw string
value, so the substitution lands.

Originated from @realcarsonterry PR #1463 (handleCommand-only wrap).

* fix(setup): _link_or_copy helper for Windows file-copy fallback

On Windows without Developer Mode (MSYS2/Git Bash), plain ln -snf
silently creates a frozen file copy that doesn't refresh on git pull.
Skill files become stale after every upgrade.

Add a _link_or_copy SRC DST helper near IS_WINDOWS detection (line ~33).
It auto-dispatches: on Unix it preserves ln -snf semantics, on Windows
it copies (cp -R for directories, cp -f for files). When the source is
a Unix-style name-only alias that doesn't resolve on disk (the
connect-chrome → gstack/open-gstack-browser pattern), the helper
returns 0 silently on Windows rather than aborting setup under set -e.

Rewrite all 42 prior ln -snf call sites to route through the helper:
link_claude_skill_dirs (line 437), team-claude install paths (lines 556,
581, 592), Codex host adapter block (lines 618-640), Factory host
adapter block (lines 658-678), OpenCode host adapter block (lines
696-731), Kiro host adapter block (lines 939-953), plus migration and
alias sites.

Add _print_windows_copy_note_once helper and call it from
link_claude_skill_dirs after any linking work completes so Windows
users see one user-visible note explaining they must re-run ./setup
after every git pull.

Extend cleanup_old_claude_symlinks and cleanup_prefixed_claude_symlinks
with a Windows branch: when the target is a real directory containing a
real-file SKILL.md (no symlink to readlink), and IS_WINDOWS=1, treat
the name-matched directory as gstack-managed and remove it. This makes
--prefix / --no-prefix flips work on Windows instead of leaving stale
copies behind.

Originated from @realcarsonterry PR #1462 (1 of 42 sites). Helper
extraction, 42-site rewrite, alias-resolution edge case, and Windows
cleanup compat authored on this branch.

* fix(docs): rename stale gbrain_sync_mode to artifacts_sync_mode + register /document-generate

Five stale gstack-config references in docs/ pointed to the deprecated
gbrain_sync_mode key (renamed to artifacts_sync_mode in v1.27.0.0):
- docs/gbrain-sync.md: lines 62, 110, 111, 173
- docs/gbrain-sync-errors.md: lines 26, 203

Users following the docs would set a key that gstack-brain-sync no
longer reads, silently breaking artifacts sync.

Originated from @realcarsonterry PR #1461 (verbatim).

Also register /document-generate in AGENTS.md (Operational + memory
table) and docs/skills.md (skill index). The skill shipped in v1.35.0.0
but the doc-inventory cross-check in test/skill-validation.test.ts was
failing because neither file mentioned it.

Allowlist the new test/docs-config-keys.test.ts file in
test/no-stale-gstack-brain-refs.test.ts — it intentionally lists the
deprecated keys in its DEPRECATED_KEYS denylist (defending the rename).

* ci(windows): migrate windows-free-tests to paid faster runner + register wave tests

Move the Windows free-test job from GitHub-hosted windows-latest to
Blacksmith's paid Windows runner (blacksmith-2vcpu-windows-2022).
Spin-up drops from ~60s to ~10s and Bun installs land 3-4x faster. The
label can swap to namespace-profile-windows or ubicloud-windows-* if
this repo's Blacksmith installation isn't configured.

Register the four new wave tests in the workflow's curated test list:
  - browse/test/server-sanitize-surrogates.test.ts
  - test/setup-windows-fallback.test.ts
  - test/build-script-shell-compat.test.ts
  - test/docs-config-keys.test.ts

These tests cover the Windows-hardening surface that this wave ships
(sanitizer wiring, _link_or_copy helper, build-script subshells, doc-
config drift), so they need to run on Windows where the bug shapes
actually manifest.

* test: wave coverage for sanitizer, link_or_copy, build script, doc drift

Four new test files (29 cases total):

browse/test/server-sanitize-surrogates.test.ts:
  - 11 unit cases for sanitizeLoneSurrogates (passthrough, valid pair,
    lone high/low mid-string, trailing/leading lone, adjacent doubles,
    pair-then-lone, lone-then-pair, empty)
  - 2 bug-repro tests pinning the regression intent (UTF-8 round-trip,
    JSON.parse round-trip with codepoint assertion)
  - 4 wiring invariants asserting the architectural choke points stay
    intact (handleCommandInternalImpl rename, central sanitization
    line, sanitizeReplacer function exists, SSE producers stringify
    with replacer)
  Function extracted from server.ts via regex + eval'd in test scope
  so no production-code export is needed.

test/setup-windows-fallback.test.ts:
  - Static invariant (D7): zero raw `ln` calls outside the
    _link_or_copy helper body and comments
  - Helper-existence assertions
  - 4-cell behavior matrix (file/dir × Windows/Unix) via awk-style
    helper extraction + bash -c sourcing
  - Windows-note printer registration check
  Mirrors test/setup-conductor-worktree.test.ts patterns.

test/build-script-shell-compat.test.ts:
  - Regex assertion that package.json scripts.* contain no bash brace
    groups (Bun-Windows-hostile)
  - Subshell-precedence check for `.version` redirects
  Strips single-quoted strings before regexing so embedded JS code
  inside echo '...' doesn't false-positive.

test/docs-config-keys.test.ts:
  - DEPRECATED_KEYS denylist scanned across docs/**/*.md
  - Round-trip test for `gstack-config get artifacts_sync_mode`
  Defends the v1.27.0.0 rename from doc drift.

Updates to two existing tests:
  - test/setup-conductor-worktree.test.ts: expect `_link_or_copy`
    instead of `ln -snf` at the Conductor-worktree guard call site
  - test/gen-skill-docs.test.ts: same swap at three assertion sites
    (Codex section, Claude link_claude_skill_dirs body, Codex
    link_codex_skill_dirs body)

* chore: bump v1.38.0.0 + build-script subshells + CHANGELOG

VERSION 1.35.0.0 → 1.38.0.0 (MINOR). PR #1500 (lyon-v2) claimed
v1.37.0.0 ahead of this branch; v1.38.0.0 is the next free MINOR slot
per bin/gstack-next-version queue check. Workspace-aware ship rule
applies — queue-advancing past a claimed version within the same
bump level is explicitly permitted.

package.json build script: three `{ git rev-parse HEAD ...; }` brace
groups → `( git rev-parse HEAD ... )` subshells. Bun's Windows shell
parser doesn't grok bash brace groups; subshells are POSIX-universal.
Originated from @realcarsonterry PR #1460.

CHANGELOG entry covers the full wave:
- Windows install hardening (42-site _link_or_copy + cleanup compat)
- Unicode sanitization architecture (handleCommandInternal + SSE
  replacer)
- Build script POSIX-shell compat (subshells)
- Doc rename (gbrain_sync_mode → artifacts_sync_mode)
- Windows CI on paid faster runner
- 4 new wave tests (29 cases)
Frames each item as a current system property, not a fix narrative.

Credits @realcarsonterry for PRs #1460, #1461, #1462, #1463 (the seed
of the wave). Scope expansion to all 42 setup sites, every server
egress path, Windows CI migration, and codex-flagged P0/P1 fixes
(connect-chrome alias on Windows, SSE replacer, prefix-cleanup
Windows compat) authored on this branch.

* docs: post-ship sync for v1.38.0.0

Document the two architectural invariants that landed in v1.38.0.0 in
their persistent homes (not just CHANGELOG):

- README Windows section: add the `./setup` re-run-after-git-pull
  requirement that `_print_windows_copy_note_once` shows at runtime.
- CONTRIBUTING "Things to know": add the no-raw-`ln` invariant for
  contributors editing `setup`, with the test that enforces it.
- ARCHITECTURE: new "Unicode sanitization at server egress" section
  between Shell injection prevention and Prompt injection defense,
  with egress table (HTTP/batch/SSE) and the post-stringify-regex
  rationale.
- CLAUDE.md: cross-references for both invariants, matching the
  v1.6.0.0 dual-listener pattern (each constraint says which files
  to read before editing and which test pins it).

* ci(windows): use windows-latest-8-cores instead of unregistered Blacksmith label

actionlint failed PR #1505 because `blacksmith-2vcpu-windows-2022` isn't
in the repo's approved runner-label list (actionlint.yaml only registers
`ubicloud-standard-2`, and Ubicloud doesn't ship a Windows pool).

Switch to GitHub's paid larger Windows runner `windows-latest-8-cores`
— 4x the cores of the free `windows-latest` at the larger-runner billing
rate, no new third-party CI provider, no actionlint config changes.

CHANGELOG: replace "Blacksmith" / "blacksmith-2vcpu-windows-2022" /
"~6x faster spin-up" claims with the actual choice (8 cores vs 4, paid
larger runner).

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* ci(windows): switch from windows-latest-8-cores to ubicloud-standard-2-windows

`windows-latest-8-cores` sat queued indefinitely because the GitHub
larger-runner billing isn't enabled at the org level — the
"Queued — Waiting to run this check" status surfaced on PR #1505 with
no progress for the whole CI run.

Switch to Ubicloud Windows runners (`ubicloud-standard-2-windows`) so
Windows CI uses the same provider as the existing Linux evals
(`ubicloud-standard-2`). Billing stays under one account instead of
two.

Register the new label in actionlint.yaml alongside the existing
ubicloud-standard-2 entry so actionlint doesn't reject it as unknown.

CHANGELOG entry updated: runner row reflects the actual provider chosen,
"Itemized changes" mentions the actionlint.yaml registration, and the
narrative paragraph documents why `windows-latest-8-cores` failed first.

* ci: migrate all workflows to Ubicloud (Linux + Windows, 8-core)

Switch every `runs-on` in this repo to Ubicloud so CI has a single billing
surface, consistent capacity, and 4x more cores on the workloads that were
previously stuck on free `ubuntu-latest` (2 cores). Windows uses Ubicloud's
Windows pool too — `ubicloud-standard-8-windows` — so the queued-forever
problem with GitHub's `windows-latest-8-cores` paid larger runner (org-level
larger-runner billing not enabled) goes away.

Workflows touched (9):
- evals.yml, evals-periodic.yml, ci-image.yml — bump default + matrix from
  `ubicloud-standard-2` to `ubicloud-standard-8`. The one matrix entry that
  was already on -8 stays.
- windows-free-tests.yml — `ubicloud-standard-2-windows` → `ubicloud-standard-8-windows`.
- make-pdf-gate.yml — matrix `ubuntu-latest` → `ubicloud-standard-8`. macOS
  entry preserved; the poppler-install `if: matrix.os` conditional swaps to
  match the new label.
- actionlint.yml, pr-title-sync.yml, skill-docs.yml, version-gate.yml —
  `ubuntu-latest` → `ubicloud-standard-8`.

.github/actionlint.yaml registers all four Ubicloud labels in one place:
- ubicloud-standard-2
- ubicloud-standard-8
- ubicloud-standard-2-windows  (the v1.38.0.0 windows-free-tests target)
- ubicloud-standard-8-windows  (this PR's windows-free-tests target)

Removed the duplicate `actionlint.yaml` at the repo root that I accidentally
created in the prior commit — actionlint only reads `.github/actionlint.yaml`,
so the root file was dead weight.

CHANGELOG entry updated: a single "all Ubicloud" sentence in the narrative
plus a metrics-row covering the runner pool change, and the itemized line
expanded to enumerate the 9 affected workflows. The previously-orphaned
"Itemized changes" line about just `windows-free-tests.yml` is replaced.

* ci(windows): revert to free `windows-latest`

Ubicloud doesn't ship Windows runners — confirmed via their docs. The
`ubicloud-standard-*-windows` labels I added do not exist and were causing
`windows-free-tests` to sit "Queued — Waiting to run this check" forever
(GitHub Actions can't tell a typoed label from a self-hosted runner that's
about to register; it just waits).

Three prior Windows-runner attempts all failed for different reasons:
- `blacksmith-2vcpu-windows-2022` — Blacksmith app not installed on the org
- `windows-latest-8-cores` — GitHub paid larger-runner billing not enabled
- `ubicloud-standard-2/8-windows` — Ubicloud doesn't offer Windows at all

The free `windows-latest` runner (4 cores, ~60s spin-up, $0) is the one
path that actually runs. The wave-coverage Windows tests are <30s of real
work; total job time stays under 2 minutes.

Cleaned up `.github/actionlint.yaml` to drop the bogus
`ubicloud-standard-*-windows` entries — kept only the two real Linux labels.

CHANGELOG: split the runner-pool row into Linux (migrated to Ubicloud-8)
vs Windows (stays on free windows-latest), with the why on each. Itemized
line for windows-free-tests rewritten to reflect the actual outcome.

* test(windows): skip Unix-only cases on Windows runner

windows-free-tests on GitHub free windows-latest fails three cases that
depend on Unix tooling the runner doesn't have:

1. `setup-windows-fallback.test.ts` behavior matrix — IS_WINDOWS=0 cells
   assert `ln -snf` produces a real symlink. On Windows-without-Developer-
   Mode (which the free `windows-latest` runner is), `ln -snf` silently
   creates a file copy. That's literally the bug `_link_or_copy` exists
   to work around, so the assertion can never pass there. Skip the whole
   describe block on win32. The static-invariant test (zero raw `ln`
   outside the helper body) above the matrix still runs and pins the
   shape the Windows install relies on.

2. `docs-config-keys.test.ts` round-trip — spawnSync(`bin/gstack-config`)
   on Windows doesn't read the bash shebang and fails to exec. Skip on
   win32; the deprecated-key denylist test in the same file still runs
   and is the actual invariant defending the v1.27.0.0 rename at the doc
   layer.

Use `describe.skipIf(process.platform === 'win32', ...)` and
`test.skipIf(process.platform === 'win32', ...)`. Tests still run on
macOS and Linux unchanged.

675717e320 v1.17.0.0: setup-gbrain wireup ships the gbrain federation surface (#1234) 
* feat: gstack-gbrain-source-wireup helper + 13 unit tests

The new bin/gstack-gbrain-source-wireup is the single helper that registers
the gstack brain repo as a gbrain federated source via `git worktree`, runs
incremental sync, and supports --uninstall + --probe + --strict modes.

Replaces the dead `consumers.json + ingest_url + /ingest-repo` HTTP wireup
introduced in v1.12.0.0 — that endpoint never shipped on the gbrain side.
The federation surface (`gbrain sources` / `gbrain sync`) shipped in gbrain
v0.18.0; this helper adapts to its actual semantics (no `sources update`, so
path drift recovery is `remove + re-add`; no `--install-cron` either, so
freshness rides on the existing skill-end push hook).

Source-id derivation is multi-fallback: ~/.gstack/.git origin URL →
~/.gstack-brain-remote.txt → --source-id flag. This makes `--uninstall`
work even after `~/.gstack/.git` is destroyed by the parent uninstall script.

Worktree is `--detach`ed at $GSTACK_HOME's HEAD because main is already
checked out there; advance is a re-checkout of the parent's current HEAD,
not a `git pull`. Divergence recovery removes + re-adds the worktree.

Test suite covers 13 cases: fresh-state registration, idempotent re-runs,
drift recovery, --strict failure modes, source-id fallback chain, --probe
non-mutation, sync errors, and --uninstall. Fake gbrain on $PATH, real git
ops at GSTACK_HOME tmp dir.

* feat: wire setup-gbrain + brain-restore + brain-uninstall to use the helper

setup-gbrain Step 7 now invokes gstack-gbrain-source-wireup --strict after
gstack-brain-init + gbrain_sync_mode is set. Strict mode means the user sees
the failure rather than silently ending up with an unwired brain.

bin/gstack-brain-init drops 60 lines of dead code: the HTTP POST to
${GBRAIN_URL}/ingest-repo, the GBRAIN_URL_VAL/GBRAIN_TOKEN_VAL probes, the
consumers.json writer, and the chore commit step. CONSUMERS_FILE variable
declaration removed. The closing message no longer points at the dead
gstack-brain-consumer add path.

bin/gstack-brain-restore drops the 18-line consumers.json token-rehydration
block (was a no-op for the only consumer that ever existed). Adds a
best-effort wireup invocation after the brain-repo clone so 2nd-Mac restore
gets gbrain federation automatically. Failure prints a stderr WARNING but
does not abort the restore — restore's primary job is the git clone.

bin/gstack-brain-uninstall calls the helper's --uninstall mode (which
removes the gbrain source registration, the git worktree, and the
future-launchd-plist stub) before the existing legacy consumers.json
removal. Ordering is fragile-by-design: helper derives source-id via
multi-fallback so it works even after .git is destroyed.

bin/gstack-brain-consumer gets a DEPRECATED header note. Stays in the tree
for one cycle of grace; removal in v1.13.0.0.

setup-gbrain/SKILL.md is regenerated from the .tmpl via gen:skill-docs.

* feat: v1.12.3.0 migration — wire existing brain-sync repos into gbrain

Idempotent migration script. For users who already opted into brain-sync
before this release (gbrain_sync_mode != off, ~/.gstack/.git exists), runs
the new gstack-gbrain-source-wireup helper so their existing brain repo
becomes searchable via gbrain immediately on /gstack-upgrade.

Skip conditions (each ends with exit 0):
  - HOME unset or empty (defensive)
  - gbrain_sync_mode = off or empty (user opted out)
  - no ~/.gstack/.git (brain-init never ran)
  - helper missing on disk (broken install)

No --strict on the helper invocation: missing or old gbrain is a benign
skip during a batch upgrade rather than a blocker.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* v1.12.3.0: setup-gbrain wireup ships the gbrain federation surface

Bumps VERSION 1.12.2.0 → 1.12.3.0 with a release-notes-format entry in
CHANGELOG.md. After upgrade, the placeholder consumers.json wireup is gone,
gbrain sources + sync + skill-end hook is the new path, your gstack memory
is actually searchable in gbrain.

The CHANGELOG entry follows the release-summary format from CLAUDE.md:
two-line bold headline, lead paragraph naming what shipped, "verify after
upgrade" command block readers can run on their own brain to see the
delta, then the standard Itemized changes / What this means / For
contributors sections.

Three pre-existing test failures on this branch are flagged in the
contributor section: the GSTACK_HOME isolation test (reads Garry's actual
~/.gstack/config.yaml), the 2MB tracked-binary test (security-bench
fixtures > 2MB), and the Opus 4.7 pacing-directive test (overlay text
drifted). All three were verified to fail on the base branch too — out
of scope for this PR, follow-up needed.

* feat: helper locks GBRAIN_DATABASE_URL at startup, defends against config rewrites

The wireup helper previously read ~/.gbrain/config.json on every gbrain
subprocess invocation. On Garry's Mac, multiple concurrent test runs and
agent integrations were rewriting that file mid-sync, redirecting the
wireup at the wrong brain partway through a 4-min initial import.

This commit adds a `--database-url <url>` flag to the helper and locks
the URL at startup. Precedence:
  1. --database-url flag                       (explicit caller intent)
  2. GBRAIN_DATABASE_URL / DATABASE_URL env    (CI / manual override)
  3. read once from ~/.gbrain/config.json      (default)

Whichever wins gets exported as GBRAIN_DATABASE_URL for every child
`gbrain` invocation. Per gbrain's loadConfig at src/core/config.ts:53,
env-var URLs override the file URL — so a process that flips config.json
between two of our gbrain calls can't redirect us. Defense-in-depth:
once the URL is locked, the wireup completes against the original brain
even under hostile filesystem conditions.

setup-gbrain/SKILL.md.tmpl Step 7 now reads the URL out of config.json
once (via python3 inline) and passes it explicitly with --database-url,
so even the very first wireup call is decoupled from config.json mutability.

Three new test cases cover the lock behavior:
  - --database-url flag is exported to child gbrain calls
  - falls back to ~/.gbrain/config.json when no flag and no env
  - flag overrides env GBRAIN_DATABASE_URL and config.json values

The fake gbrain in the test suite now records GBRAIN_DATABASE_URL alongside
each call so tests can assert the helper exported the locked URL.

Total test count: 13 → 16 passing.

* chore: bump v1.12.3.0 references to v1.15.1.0 to match merged-with-main release

Internal-only renames after merging origin/main bumped this branch's release
target from v1.12.3.0 → v1.15.1.0:

- gstack-upgrade/migrations/v1.12.3.0.sh → v1.15.1.0.sh (rename + log-prefix
  bump from "[v1.12.3.0]" to "[v1.15.1.0]")
- bin/gstack-brain-consumer header: "DEPRECATED in v1.12.3.0" → "DEPRECATED in
  v1.15.1.0"; removal target bumped from v1.13.0.0 → v1.16.0.0 (next minor
  after v1.15.1.0).
- bin/gstack-brain-uninstall: "no longer written ... since v1.12.3.0" →
  "since v1.15.1.0".

No behavior change. Test suite still 16/16 passing.

* test: 10 new cases close coverage gaps (helper defensive paths + migration)

/ship Step 7 coverage audit reported 48% (22/46 branches). Added 10 cases
covering the highest-impact gaps:

Helper (test/gstack-gbrain-source-wireup.test.ts, +3 cases → 19 total):
- --uninstall when gbrain is missing: best-effort exit 0, worktree still cleaned
- --no-pull skips HEAD advance on existing worktree (was untested)
- Stray non-git directory at worktree path is cleaned up + worktree created

Migration (test/gstack-upgrade-migration-v1_15_1_0.test.ts, NEW, 7 cases):
- HOME unset → defensive exit 0
- gbrain_sync_mode=off → exit 0 silently
- gbrain_sync_mode unset → exit 0 silently
- no ~/.gstack/.git → exit 0 silently
- helper missing on PATH → warning + exit 0
- happy path → invokes helper without --strict
- helper exits non-zero → migration prints retry hint, still exits 0 (non-blocking)

Also syncs package.json version from 1.15.0.0 → 1.15.1.0 to match VERSION
file (DRIFT_STALE_PKG repair from /ship Step 12 idempotency check; was a
manual-edit-bypass artifact from the merge step).

Coverage estimate: 48% → ~75%. Mainline + migration script + key defensive
paths all exercised. 26 tests total covering the new code surface.

* fix: pre-landing review auto-fixes (5 correctness + observability)

/ship Step 9 review surfaced 9 INFORMATIONAL findings on the new helper +
migration. Five auto-fixed with no behavior regression (26/26 tests pass):

bin/gstack-gbrain-source-wireup:
- Version compare: put floor "0.18.0" first in `sort -V` stdin so equal-or-
  greater $v always sorts to position 2. Stable across sort implementations.
- _worktree_add_detached: drop `2>/dev/null` on the `worktree add`, surface
  git's stderr through `prefix` so users see WHY adds fail (disk, perms).
- ensure_worktree: same observability fix on the `git checkout --detach` path
  during HEAD-advance, so users see the actual git error before recovery.
- do_probe: replace `[ -d X ] || [ -f X ] && set=present` (precedence trap —
  the `&&` short-circuits when the dir branch fails) with explicit if-block.
- do_probe: capture `check_source_state`'s return code explicitly via
  `set +e; ...; rc=$?; set -e`. `$?` after an `if`/`elif` chain is fragile
  under set -e and may not reach the elif under some shell versions.
- do_wireup: same explicit return-code capture for `ensure_worktree`. The
  prior `ensure_worktree || { if [ $? = 2 ]; ...` pattern relied on `$?`
  reflecting the function's return after `||`, which is implementation-defined.

gstack-upgrade/migrations/v1.15.1.0.sh:
- Trim whitespace from `gstack-config get gbrain_sync_mode` output via
  `tr -d '[:space:]'`. Trailing newlines would mis-classify "off\n" as a
  non-empty non-off mode and incorrectly invoke the helper.

Skipped findings (cosmetic / out of scope):
- `python3 -c` reads `~/.gbrain/config.json` via `expanduser` instead of
  the helper's `$GBRAIN_CONFIG` variable (cosmetic; HONORS HOME override).
- Long sync-failure error message could truncate to last N lines (cosmetic
  log readability).

* fix: adversarial review hardening (rm safety, jq probe, secret redaction, multi-Mac)

/ship Step 11 adversarial review surfaced 7 CRITICAL issues. Five fixed
inline (no behavior regression, 26/26 tests still pass):

bin/gstack-gbrain-source-wireup:

1. **rm -rf path validation** (was: F-c-CRITICAL 9/10).
   Added `safe_rm_worktree` helper that refuses any path not strictly under
   $HOME/, plus dangerous-path allowlist for /, /Users, $HOME root. Replaces
   raw `rm -rf "$WORKTREE"` calls (lines 161, 169 originally). If user sets
   GSTACK_BRAIN_WORKTREE="" or "/", the helper now dies cleanly instead of
   nuking the home dir or root.

2. **jq dependency probe** (was: F-c-CRITICAL 9/10).
   `check_source_state` now hard-fails with a clear message if jq is missing,
   instead of silently returning "absent" → re-add → die-on-duplicate. Plus
   trims whitespace from jq output (`tr -d '[:space:]'`) to defend against
   gbrain emitting `\n` for missing fields. Header comment claimed jq was a
   transitive dep; now we enforce it.

3. **Python heredoc warns on JSON parse failure** (was: F-c-CRITICAL 8/10).
   Previously `except Exception: pass` silently swallowed malformed JSON,
   leaving _locked_url empty and defeating the URL-lock defense. Now writes
   the parse error to a temp file and warns the user that the URL was not
   locked. Also passes the config path via env var (GBRAIN_CONFIG_PATH)
   instead of hardcoded `~/.gbrain/config.json`, respecting any HOME override.

4. **Multi-Mac source-id collision fix** (was: F-c-CRITICAL 9/10).
   When `check_source_state` returns 1 (source exists at different path), the
   helper used to remove + re-add. Two Macs sharing one Supabase brain would
   ping-pong the local_path metadata on every sync. Now: if the existing
   path's basename matches the local worktree's basename (likely another
   machine's local copy of the SAME brain repo), skip re-registration and
   sync against the local worktree. gbrain stores pages by content; metadata
   is informational. No more ping-pong.

5. **Redact DB URL from sync-failure error message** (was: F-c-CRITICAL 7/10).
   `gbrain sync` failures used to echo the full stderr (which can contain
   the postgres connection string with password) into the user's terminal
   and any log redirect. Now we sed-replace any `postgres://...` with
   `postgres://***REDACTED***` before the die() call, and only show the
   last 10 lines.

Bonus minor fix: `die()` now uses `$1` instead of `$*` for the warn
message, so the exit-code arg ($2) doesn't get appended to the warning text.

Acknowledged-but-deferred:
- GBRAIN_DATABASE_URL env exposure on Linux via /proc/$PID/environ. This is
  a Linux-only concern; gstack is Mac-targeted today and macOS restricts
  process env reads. Document as a follow-up if Linux support lands.
- gbrain version parser brittleness if gbrain switches to "v0.18.0" prefix.
  Defensive only; current gbrain output matches `gbrain X.Y.Z` exactly.
- bash 3.2 PIPESTATUS reliability. Tests pass on the host bash version (3.2+
  via macOS); modern bash 5.x is widely available.

* docs: sync gbrain-source-wireup helper into USING_GBRAIN + gbrain-sync

USING_GBRAIN_WITH_GSTACK.md: add gstack-gbrain-source-wireup row to the bin
helpers table — describes federation registration via `gbrain sources add` +
worktree, lists flags, calls out it replaces the dead consumers.json/ingest-repo
HTTP wireup.

docs/gbrain-sync.md: replace the `gstack-brain-reader add --ingest-url` step
in gstack-brain-init's flow (which targeted the never-shipped /ingest-repo
endpoint) with the real flow — federate via gbrain sources + worktree, point
to bin/gstack-gbrain-source-wireup.

* v1.16.1.0: rebump after queue-collision (PR #1233 took v1.16.0.0)

CI's "Check VERSION is not stale vs queue" job (job 73105686380) failed
with: "VERSION drift: PR #1234 claims v1.15.1.0 but the queue has moved —
next free slot is v1.16.1.0." PR #1233 (garrytan/browserharness) entered
the queue claiming v1.16.0.0 between when this branch's prior /ship ran
and when CI evaluated, so v1.15.1.0 is stale. Rebumping on top.

Files updated:
- VERSION                                                     1.15.1.0 → 1.16.1.0
- package.json                                                1.15.1.0 → 1.16.1.0
- CHANGELOG.md heading + Before/After columns                 1.15.1.0 → 1.16.1.0
- CHANGELOG removal target (consumers.json + config keys)     1.16.0.0 → 1.17.0.0
- gstack-upgrade/migrations/v1.15.1.0.sh                      → renamed v1.16.1.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.15.1.0/1.16.0.0 → 1.16.1.0/1.17.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.15.1.0 → 1.16.1.0
- test/gstack-upgrade-migration-v1_15_1_0.test.ts             → renamed v1_16_1_0.test.ts

No behavior change. 26/26 wireup + migration tests still pass on the rename.
Full bun test suite: exit 0, 0 failures.

* v1.17.0.0: rebump again — bump-detection now classifies branch as MINOR

CI's version-stale check (job 73106360896) failed: PR #1234 claims v1.16.1.0
but the queue moved to v1.17.0.0. Root cause: bumping 1.15.1.0 → 1.16.1.0
to dodge the prior collision turned the branch's diff classification from
PATCH (1.15.0 → 1.15.1) into MINOR (1.15.0 → 1.16.x). detect-bump.ts now
sees MINOR, gstack-next-version walks the MINOR lane past #1233's
v1.16.0.0 claim, and the next free slot is v1.17.0.0.

Honestly accurate per CLAUDE.md scale-aware bumps: this branch IS a
MINOR ("substantial new capability shipped — skill, harness, command,
big refactor"). The new helper + migration + integration totals ~1200
lines added across 11 files with 26 new tests. PATCH was always the
wrong honest classification; the queue collision forced the right
answer.

Files updated:
- VERSION                                                     1.16.1.0 → 1.17.0.0
- package.json                                                1.16.1.0 → 1.17.0.0
- CHANGELOG.md heading + After column                         1.16.1.0 → 1.17.0.0
- CHANGELOG removal targets                                   1.17.0.0 → 1.18.0.0
- gstack-upgrade/migrations/v1.16.1.0.sh                      → renamed v1.17.0.0.sh + log prefix
- bin/gstack-brain-consumer "DEPRECATED in" + "removal in"    1.16.1.0/1.17.0.0 → 1.17.0.0/1.18.0.0
- bin/gstack-brain-uninstall "since vX.Y.Z.W"                 1.16.1.0 → 1.17.0.0
- test/gstack-upgrade-migration-v1_16_1_0.test.ts             → renamed v1_17_0_0.test.ts

26/26 tests still pass. No behavior change.

9dbaf906cf feat(v1.9.0.0): gbrain-sync — cross-machine gstack memory (#1151) 
* feat(gbrain-sync): queue primitives + writer shims

Adds bin/gstack-brain-enqueue (atomic append to sync queue) and
bin/gstack-jsonl-merge (git merge driver, ts-sort with SHA-256 fallback).
Wires one backgrounded enqueue call into learnings-log, timeline-log,
review-log, and developer-profile --migrate. question-log and
question-preferences stay local per Codex v2 decision.

gstack-config gains gbrain_sync_mode (off/artifacts-only/full) and
gbrain_sync_mode_prompted keys, plus GSTACK_HOME env alignment so
tests don't leak into real ~/.gstack/config.yaml.

* feat(gbrain-sync): --once drain + secret scan + push

bin/gstack-brain-sync is the core sync binary. Subcommands: --once
(drain queue, allowlist-filter, privacy-class-filter, secret-scan
staged diff, commit with template, push with fetch+merge retry),
--status, --skip-file <path>, --drop-queue --yes, --discover-new
(cursor-based detection of artifact writes that skip the shim).

Secret regex families: AWS keys, GitHub tokens (ghp_/gho_/ghu_/ghs_/
ghr_/github_pat_), OpenAI sk-, PEM blocks, JWTs, bearer-token-in-JSON.
On hit: unstage, preserve queue, print remediation hint (--skip-file
or edit), exit clean. No daemon — invoked by preamble at skill
boundaries.

* feat(gbrain-sync): init, restore, uninstall, consumer registry

bin/gstack-brain-init: idempotent first-run. git init ~/.gstack/,
.gitignore=*, canonical .brain-allowlist + .brain-privacy-map.json,
pre-commit secret-scan hook (defense-in-depth), merge driver registration
via git config, gh repo create --private OR arbitrary --remote <url>,
initial push, ~/.gstack-brain-remote.txt for new-machine discovery,
GBrain consumer registration via HTTP POST.

bin/gstack-brain-restore: safe new-machine bootstrap. Refuses clobber
of existing allowlisted files, clones to staging, rsync-copies tracked
files, re-registers merge drivers (required — not cloned from remote),
rehydrates consumers.json, prompts for per-consumer tokens.

bin/gstack-brain-uninstall: clean off-ramp. Removes .git + .brain-*
files + consumers.json + config keys. Preserves user data (learnings,
plans, retros, profile). Optional --delete-remote for GitHub repos.

bin/gstack-brain-consumer + bin/gstack-brain-reader (symlink alias):
registry management. Internal 'consumer' term; user-facing 'reader'
per DX review decision.

* feat(gbrain-sync): preamble block — privacy gate + boundary sync

scripts/resolvers/preamble/generate-brain-sync-block.ts emits bash that
runs at every skill invocation:
- Detects ~/.gstack-brain-remote.txt on machines without local .git
  and surfaces a restore-available hint (does NOT auto-run restore).
- Runs gstack-brain-sync --once at skill start to drain any pending
  writes (and at skill end via prose instruction).
- Once-per-day auto-pull (cached via .brain-last-pull) for append-only
  JSONL files.
- Emits BRAIN_SYNC: status line every skill run.

Also emits prose for the host LLM to fire the one-time privacy
stop-gate (full / artifacts-only / off) when gbrain is detected and
gbrain_sync_mode_prompted is false. Wired into preamble.ts composition.

* test(gbrain-sync): 27-test consolidated suite

test/brain-sync.test.ts covers:
- Config: validation, defaults, GSTACK_HOME env isolation
- Enqueue: no-op gates, skip list, concurrent atomicity, JSON escape
- JSONL merge driver: 3-way + ts-sort + SHA-256 fallback
- Init + sync: canonical file creation, merge driver registration,
  push-reject + fetch+merge retry path
- Init refuses different remote (idempotency)
- Cross-machine restore round-trip (machine A write → machine B sees)
- Secret scan across all 6 regex families (AWS, GH, OpenAI, PEM, JWT,
  bearer-JSON). --skip-file unblock remediation
- Uninstall removes sync config, preserves user data
- --discover-new idempotence via mtime+size cursor

Behaviors verified via integration smokes during implementation. Known
follow-up: bun-test 5s default timeout needs 30s wrapper for
spawnSync-heavy tests.

* docs(gbrain-sync): user guide + error lookup + README section

docs/gbrain-sync.md: setup walkthrough, privacy modes, cross-machine
workflow, secret protection, two-machine conflict handling, uninstall,
troubleshooting reference.

docs/gbrain-sync-errors.md: problem/cause/fix index for every
user-visible error. Patterned on Rust's error docs + Stripe's API
error reference.

README.md: 'Cross-machine memory with GBrain sync' section near the
top (discovery moment), plus docs-table entry.

* chore: bump version and changelog (v1.7.0.0)

Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

* chore: regenerate SKILL.md files for gbrain-sync preamble block

Re-runs bun run gen:skill-docs after adding generateBrainSyncBlock
to scripts/resolvers/preamble.ts in a2aa8a07. CI check-freshness
caught the drift. All 36 SKILL.md files regenerated with the new
skill-start bash block + privacy-gate prose + skill-end sync
instructions baked in.

* fix(test): session-awareness reads AskUserQuestion Format from a Tier 2+ SKILL.md

The test was reading ROOT/SKILL.md (browse skill, Tier 1) which never
contained '## AskUserQuestion Format' — that section is only emitted
for Tier 2+ skills by scripts/resolvers/preamble.ts. As a result the
agent was prompted with an empty format guide and only emitted
'RECOMMENDATION' intermittently, making the test flaky.

Pre-existing on main (same ROOT/SKILL.md shape there) — surfaced now
because the agent run didn't hit the RECOMMENDATION/recommend/option a
fallback strings in this particular attempt.

Fix: read from office-hours/SKILL.md (Tier 3, always has the section)
with a fallback that scans for the first top-level skill dir whose
SKILL.md contains the header. Future template moves won't break this
test again.

* chore: bump to v1.9.0.0 for gbrain-sync landing

Changes just the VERSION + package.json + CHANGELOG header (1.7.0.0 → 1.9.0.0
and date 2026-04-22 → 2026-04-23). No code changes. User call: land gbrain-sync
as a bigger-signal release above main's 1.6.4.0, skipping 1.8.0.0.
