Garry Tan 64f9aafa1e v1.44.1.0 fix wave: post-windhoek paper-cut — 9 community PRs in one bundle (#1682)
* fix(office-hours): #1671 — session writer was writing to the legacy file

User-visible symptom: returning /office-hours users get the same closing
pitch every visit, no matter how many times they've run the skill. The
welcome_back tier (which exists specifically to skip the pitch for
returning users) was unreachable. Live since 2026-04-18 / v1.0.0.0 on
every fresh-$HOME user.

Root cause: the v1.0.0.0 migration moved the read path to
~/.gstack/developer-profile.json but left the writer in
office-hours/SKILL.md.tmpl writing to the legacy
~/.gstack/builder-profile.jsonl. Reader and writer disagreed on storage,
so SESSION_COUNT never incremented and /office-hours always treated the
user as a first-timer.

Fix:
- bin/gstack-developer-profile: new --log-session subcommand that
  read-modify-writes developer-profile.json's sessions[] array (atomic
  mktemp+mv, signals/resources/topics aggregation, gbrain-enqueue mirror
  of gstack-timeline-log:40). Naming matches the gstack-*-log family verb.
- bin/gstack-developer-profile: do_read filters mode:"resources" entries
  when picking LAST_PROJECT/LAST_ASSIGNMENT/LAST_DESIGN_TITLE so the Phase
  6 resources auto-append doesn't clobber real-session state. Latent bug
  that was masked by the broken writer; activated by the fix.
- office-hours/SKILL.md.tmpl: lines 490 + 893 swap echo >> for --log-session.
- test/gstack-developer-profile.test.ts: +8 tests covering --log-session
  contract (regression, aggregation, dedup, validation, ts handling) plus
  the mode-filter regression. All 8 fail on main, all 8 pass with this fix.
- test/static-no-legacy-writes.test.ts: new static-grep invariant walking
  every skill dir to prevent future regressions onto the legacy file.

Affected users: stranded builder-profile.jsonl entries are not recovered
automatically by this PR. On their next /office-hours run, the first new
session lands in welcome_back; past data stays in the legacy file (still
readable by other tools during deprecation). Most pre-existing users have
only a handful of stranded sessions.

See docs/designs/FIX_1671_PROFILE_MIGRATION.md for scope decisions
(RC2/RC3 follow-ups, what was intentionally left out, and why).

Issue: #1671

* test(office-hours): refine #1671 invariant regex comment for literal-path scope

Clarifies that the WRITE_PATTERN regex catches literal-path writes only;
variable-indirected writes (FILE=...; echo >> "$FILE") are not detected.
The SKILL.md.tmpl assertions in the same suite pin the exact #1671
regression class directly; this regex is a backstop, not a flow analyzer.

* fix(timeline): pass read filters as data

* feat(next-version): support monorepo VERSION paths via --version-path + .gstack/version-path

The workspace-aware ship queue hardcoded the VERSION file at the repo root.
In monorepos where versioning is subproject-scoped (one app inside a larger
repo), every PR's VERSION lookup 404s, the queue silently empties, and
parallel /ship sessions all bump from "current main + 1" — producing a
cascade of slot collisions.

Repro: tinas-second-brain repo. Root VERSION is absent; the real VERSION
lives at "Tinas Second Brain/health-tracker/VERSION". In one day, four
sequential collisions: 0.4.0.1 -> 0.5.0.0 -> 0.5.0.1 -> 0.5.0.2 -> 0.5.0.3.

Fix: add a --version-path flag and a repo-local .gstack/version-path
config file. Resolution priority: CLI flag > .gstack/version-path > "VERSION".
The resolved path threads through all four call sites — git show
origin/<base>:<path>, the GitHub Contents API, the GitLab files API, and
the local sibling-worktree scan — and shows up in the JSON output as
version_path so /ship and operators can see what got picked.

The previous warning "could not fetch VERSION (fork or private)" was
misleading whenever the real cause was wrong path. The new wording names
the path that 404'd and hints at the two knobs.

Backward-compatible: no flag, no config, no change in behavior.

Tests: 6 unit tests for resolveVersionPath (priority, parsing, blank /
missing / empty edge cases) + a second integration smoke that drives
--version-path end-to-end and asserts it surfaces in JSON output.

* fix(investigate): support standalone freeze hook path

* fix(browse): clarify localhost bind failures

* fix(migration): defer v1.40.0.0 done-marker until every repair succeeds (#1581)

The v1.40.0.0 migration unconditionally `touch`ed its done-marker, even
when the jq-gated `.brain-privacy-map.json` patch was skipped because jq
was missing on the user's machine. On subsequent runs, the script
short-circuited on the marker so the privacy-map repair never landed.
Federation sync then silently dropped `/plan-eng-review` test plans.

Track every failure mode via a single `incomplete` flag: jq missing,
malformed JSON, jq mutation failure, tempfile creation failure, `mv`
failure, allowlist append failure, gitattributes append failure. The
marker is written only when `incomplete=0`, so the migration runner
retries on the next /gstack-upgrade once the prerequisites are met.

* test(migration): unit tests for v1.40.0.0 deferred done-marker fix (#1581)

8 cases pinning the fix:

- Case 1 (happy path): jq present, fresh privacy-map → all three files
  patched, marker written.
- Case 2 (regression for #1581): jq missing, privacy-map present →
  marker must NOT be written. Fails against the buggy script, passes
  against the fix.
- Case 3 (recovery): jq missing, then jq restored → patch lands on
  second run.
- Case 4 (idempotency): privacy-map already has correct entry →
  no mutation, marker written.
- Case 5 (fresh-init): privacy-map file absent → allowlist + gitattrs
  patched, marker written.
- Case 6 (malformed JSON): broken privacy-map JSON → no marker, no
  mutation.
- Case 7 (jq mutation failure): fake jq returning 1 → no marker,
  tempfile cleaned up.
- Case 8 (allowlist append failure): read-only allowlist → no marker.

Tests use spawnSync('bash', [MIGRATION], …) with isolated tmpHomes.
"jq missing" sets PATH to a curated dir of symlinks to standard utils,
omitting jq; "jq mutation fails" uses an `exit 1` shim. Avoids
blanket-clearing PATH (which would hide bash/grep/etc).

* fix(brain-sync): make artifact sync work on Windows (discover-new + drain)

Automatic artifact sync was fully non-functional on Windows (Git Bash):
--discover-new enqueued nothing and the --once drain staged nothing, so
artifacts_sync_mode looked active but no artifacts ever reached the repo.
Three independent Windows-only causes in bin/gstack-brain-sync:

1. discover-new matched os.path.relpath (backslash separators on Windows)
   against the forward-slash allowlist globs, so no nested file ever matched.
   Normalized the relpath to "/".
2. discover-new enqueued via subprocess.run([gstack-brain-enqueue, rel]), but
   Windows Python cannot exec a bash-shebang script, so nothing was enqueued
   even once matched. Now appends to the queue in-process.
3. compute_paths_to_stage ends in print(p); Windows Python emits CRLF, the
   bash `read -r` keeps the trailing CR, and `git add -- "path<CR>"` matches
   nothing under `2>/dev/null || true`. Now strips the CR before staging.

The in-process enqueue mirrors gstack-brain-enqueue's contract: one atomic
O_APPEND write per record (each line < PIPE_BUF) so a parallel writer-shim
append can't interleave mid-record, and the discover cursor advances only
after the write succeeds, so a failed write retries instead of silently
recording the file as synced. Skip-list entries are separator-normalized on
both the discover and drain (compute_paths_to_stage) sides, so a backslash
.brain-skip.txt entry can't be honored at discovery yet bypassed at commit.

Adds test/brain-sync-windows-paths.test.ts (static invariants -- behavioral
spawn tests cannot run on the Windows lane, since Node/Bun cannot exec the
bin/ shebang scripts there) and wires it into windows-free-tests.yml.
Verified red->green and end-to-end on Windows 11 / Git Bash; macOS/Linux
behavior unchanged (os.sep is already "/", no CRLF, compute path logic
unchanged besides the shared skip normalization).

* fix: detect bun.lock (Bun v1.2+ text lockfile) in diff-scope CONFIG

gstack-diff-scope only matched the legacy binary lockfile `bun.lockb`
but not the newer text-based `bun.lock` introduced in Bun v1.2+.
Projects using current Bun versions were silently missing the
SCOPE_CONFIG signal when only the lockfile changed.

* fix(ios-qa): resolve CoreDevice tunnel via devicectl + keep tunnel alive

The daemon's tunnel bootstrap used `dns.resolve6` to look up
`<device>.coredevice.local`, which fails with ESERVFAIL on macOS 26.x
(Darwin 25.x) because Node's resolve6 path goes through libresolv and
does NOT consult mDNSResponder. `dns.lookup` (getaddrinfo) does.

Even when resolution works, CoreDevice in Xcode 26 only holds the
USB tunnel up while a devicectl command is in-flight, so the IPv6 ULA
becomes unroutable within ~10-15s of idle and subsequent proxy
requests time out.

Two-part fix:

  1. Resolution order is now (a) `xcrun devicectl device info details
     --json-output` to read `result.connectionProperties.tunnelIPAddress`
     directly, (b) mDNS via `dns.lookup`, (c) legacy `dns.resolve6` as
     a last-ditch fallback.
  2. After a successful bootstrap the daemon spawns a periodic
     `devicectl device info details` (~5s) to keep the tunnel session
     alive. Cleaned up on SIGINT/SIGTERM/exit.

Adds tests for `getDeviceTunnelIPv6FromDevicectl`, the
`resolveTunnelIPv6` fallback chain, and `startTunnelKeepalive`.
Existing bootstrap tests updated to include the new
`device info details` spawn step.

Tested against: iPhone 12 Pro on iOS 26.x via Mac Mini M-series
running macOS Sequoia 15.x / Darwin 25.3.0.

* chore(release): v1.44.1.0 — 9-PR community fix wave (post-windhoek paper-cut)

Bump VERSION + CHANGELOG entry. Wave covers /office-hours session
counter, iOS QA macOS 26 tunnels, Windows brain-sync, browse server
bind diagnostics, monorepo VERSION layouts, /investigate freeze hook
on standalone installs, gstack-timeline-read quote injection,
v1.40.0.0 migration on jq-less machines, bun.lock detection.

Garry Tan 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.

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

* 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.

* fix: Korean/CJK IME input and rendering in Sidebar Terminal

Fixes #1272

This commit addresses three separate Korean/CJK bugs in the Sidebar Terminal:

**Bug 1 - IME Input**: Korean text typed via IME composition was not
reaching the PTY correctly. Added compositionstart/compositionend event
listeners to suppress partial jamo fragments and only send the final
composed string.

**Bug 2a - Font Rendering**: Added CJK monospace font fallbacks
("Noto Sans Mono CJK KR", "Malgun Gothic") to both the xterm.js
fontFamily config and the CSS --font-mono variable. This ensures
consistent cell-width calculations for Korean characters.

**Bug 2b - UTF-8 Boundary Detection**: Added buffering logic to prevent
multi-byte UTF-8 characters (Korean is 3 bytes) from being split across
WebSocket chunks. This follows the same pattern as PR #1007 which fixed
the sidebar-agent path, but extends it to the terminal-agent path.

Special thanks to @ldybob for the excellent root cause analysis and
proposed solutions in issue #1272.

Tested on WSL2 + Windows 11 with Korean IME.

* fix(ship): tighten Plan Completion gate (VAS-449 remediation)

VAS-446 shipped with a PLAN.md acceptance criterion (domain-hq has
/docs/dashboard.md) silently skipped. /ship's Plan Completion subagent
existed at ship time (added in v1.4.1.0) but the gate let the failure
through. Four structural fixes:

1. Path concreteness rule: items naming a concrete filesystem path MUST
   be classified DONE/NOT DONE via [ -f <path> ], never UNVERIFIABLE.
2. Validator detection: CONTENT-SHAPE items scan target repo's
   package.json for validate-* scripts and run them before falling back
   to UNVERIFIABLE.
3. Per-item UNVERIFIABLE confirmation: replaces blanket "I've checked
   each one" with per-item Y/N/D loop. The blanket-confirm path is the
   exact failure VAS-449 surfaced.
4. Subagent fail-closed: if Plan Completion subagent + inline fallback
   both fail, surface explicit AskUserQuestion instead of silent pass.
   Replaces the prior "Never block /ship on subagent failure" fail-open.

Locked in by test/ship-plan-completion-invariants.test.ts (5 assertions,
no LLM dependency, ~60ms).

* fix(browse): bash.exe wrap for telemetry on Windows

reportAttemptTelemetry() in browse/src/security.ts calls spawn(bin, args)
where bin is the gstack-telemetry-log bash script. On Windows this fails
silently with ENOENT — CreateProcess can't dispatch on shebang lines.

Adopts v1.24.0.0's Bun.which + GSTACK_*_BIN override pattern (from
browse/src/claude-bin.ts:resolveClaudeCommand, introduced in #1252) for
resolving bash.exe. resolveBashBinary() honors GSTACK_BASH_BIN absolute-path
or PATH-resolvable override, falling back to Bun.which('bash') which finds
Git Bash on the standard Windows install.

buildTelemetrySpawnCommand() wraps the script invocation on win32 only;
POSIX path is bit-identical. Returns null when bash can't be resolved on
Windows so caller skips spawn — local attempts.jsonl audit trail keeps
working without surfacing a Windows-only failure.

8 new unit tests cover resolveBashBinary (POSIX bash, absolute override,
quote-stripping, BASH_BIN fallback, empty-PATH null) and buildTelemetrySpawnCommand
(POSIX pass-through, win32 bash wrap, win32 null on unresolvable, arg-array
immutability).

POSIX path is bit-identical — Bun.which('bash') on Linux/macOS returns the
same /bin/bash or /usr/bin/bash that the old hardcoded spawn relied on.

* fix(make-pdf): Bun.which-based binary resolution for browse + pdftotext on Windows

Extends v1.24.0.0's Bun.which + GSTACK_*_BIN override pattern (introduced in
browse/src/claude-bin.ts via #1252) to the two other binary resolvers in the
codebase: make-pdf/src/browseClient.ts:resolveBrowseBin and
make-pdf/src/pdftotext.ts:resolvePdftotext.

Same Windows quirks (fs.accessSync(X_OK) degrades to existence-check; `which`
isn't available outside Git Bash; bun --compile --outfile X emits X.exe), same
Bun.which-based fix shape, same env override convention.

Changes:
  - GSTACK_BROWSE_BIN / GSTACK_PDFTOTEXT_BIN as the v1.24-aligned overrides;
    BROWSE_BIN / PDFTOTEXT_BIN remain as back-compat aliases.
  - Bun.which() replaces execFileSync('which', ...) for PATH lookup. Handles
    Windows PATHEXT natively; no more `where`-vs-`which` branch.
  - findExecutable(base) helper exported from each module, probes .exe/.cmd/.bat
    after the bare-path miss on win32. Linux/macOS behavior is bit-identical
    (isExecutable short-circuits before the win32 branch ever runs).
  - macCandidates renamed posixCandidates (always was — /opt/homebrew, /usr/local,
    /usr/bin). No Windows candidates added; Poppler installs scatter across
    Scoop/Chocolatey/portable zips and guessing causes false positives.
  - Error messages get a Windows install hint (scoop install poppler / oschwartz10612)
    and `setx` example for GSTACK_*_BIN.
  - Pre-existing test 'honors BROWSE_BIN when it points at a real executable'
    was hardcoded /bin/sh — made cross-platform via a REAL_EXE constant
    (cmd.exe on win32, /bin/sh on POSIX). Was a Windows-CI blocker on its own.

Coordination: PR #1094 (@BkashJEE) covered browseClient.ts independently with a
narrower scope; this PR's pdftotext + cross-platform tests + GSTACK_*_BIN naming
are additive. Either order of merge works.

Test plan:
  - bun test make-pdf/test/browseClient.test.ts make-pdf/test/pdftotext.test.ts
    on win32 — 29 pass, 0 fail (12 new assertions: findExecutable POSIX/win32/null,
    resolveBrowseBin GSTACK_BROWSE_BIN + BROWSE_BIN + precedence + quote-strip,
    same shape for resolvePdftotext + Windows install hint in error message).
  - POSIX branch unchanged — fs.accessSync(X_OK) on Linux/macOS short-circuits
    before any win32 logic runs, matching the v1.24 claude-bin.ts pattern.

* fix(browse): NTFS ACL hardening for Windows state files via icacls

gstack's ~/.gstack/ state directory holds bearer tokens, canary tokens, agent
queue contents (with prompt history), session state, security-decision logs,
and saved cookie bundles — all written with { mode: 0o600 } / 0o700. On Windows,
those mode bits are a silent no-op: Node's fs module doesn't translate POSIX
modes to NTFS ACLs, and inherited ACLs leave every "restricted" file readable
by other principals on the machine (verified via icacls — six ACEs, the
intended user is the LAST of six).

Threat model is non-trivial on:
  - Self-hosted CI runners (different service account on the same Windows box
    can read developer tokens, canary tokens, prompt history)
  - Shared development machines (agencies, studios, lab environments)
  - Multi-tenant servers with shared home directories

Orthogonal to v1.24.0.0's binary-resolution work — complementary at the write
side. v1.24's bin/gstack-paths resolves ~/.gstack/ correctly across plugin /
global / local installs; this PR ensures files written into those resolved
paths actually get the POSIX 0o600 semantic translated to NTFS.

The fix:
  - New browse/src/file-permissions.ts (158 LOC, 5 public + 1 test-reset).
    restrictFilePermissions / restrictDirectoryPermissions wrap chmod (POSIX)
    or icacls /inheritance:r /grant:r <user>:(F) (Windows). writeSecureFile /
    appendSecureFile / mkdirSecure are drop-in wrappers for the common patterns.
  - 19 call sites converted across 9 source files: browser-manager.ts,
    browser-skill-write.ts, cli.ts, config.ts, meta-commands.ts,
    security-classifier.ts, security.ts (4 sites), server.ts (5 sites),
    terminal-agent.ts (8 sites), tunnel-denial-log.ts.
  - (OI)(CI) inheritance flags on directories mean files created via fs.write*
    *inside* an mkdirSecure-created dir inherit the owner-only ACL automatically
    — important for tunnel-denial-log.ts where appends use async fsp.appendFile.

Error handling: icacls failures (nonexistent path, missing icacls.exe, hardened
environments) log a one-shot warning to stderr and proceed. Once-per-process
gating prevents log spam if the condition persists. Filesystem stays
functional; the file just ends up with inherited ACLs.

Test plan:
  - bun test browse/test/file-permissions.test.ts — 13 pass, 0 fail (POSIX
    mode-bit assertions, Windows no-throw, mkdir idempotence, recursive
    creation, Buffer payloads, append-creates-then-reapplies-once semantics)
  - bun test browse/test/security.test.ts — 38 pass, 0 fail (existing security
    test suite plus the bash-binary resolution tests added in fix #1119; the
    converted writeFileSync/appendFileSync/mkdirSync sites in security.ts
    integrate cleanly)
  - Empirical icacls before/after on a real file — 6 ACEs → 1 ACE
  - bun build typecheck on all modified files — clean (server.ts has a
    pre-existing playwright-core/electron resolution issue unrelated to this PR)

POSIX behavior is bit-identical to old code — fs.chmodSync(path, 0o6XX) on the
helper's POSIX branch matches the inline { mode: 0o6XX } it replaces. Linux
and macOS see no behavior change.

Inviting pushback on three judgment calls (in PR description):
  1. icacls vs npm library
  2. ACL scope — just user, or user + SYSTEM?
  3. Graceful degradation — once-per-process warn, not silent, not hard-fail.

* fix(browse): declare lastConsoleFlushed to restore console-log persistence

flushBuffers() references a `lastConsoleFlushed` cursor at server.ts:337
and assigns it at :344, but the `let lastConsoleFlushed = 0;`
declaration is missing — only the network and dialog siblings are
declared at lines 327-328.

Result: every 1-second flushBuffers tick (line 376) throws
`ReferenceError: lastConsoleFlushed is not defined`, gets swallowed by
the catch at line 369 ("[browse] Buffer flush failed: ..."), and the
console branch's append never runs. browse-console.log is never
written in any production deployment since this regressed.

Discovered by stress-testing the daemon with 15 concurrent CLIs against
cold state — the race surfaced the buffer-flush error spam in one
spawned daemon's stderr. Verified by running the daemon against a real
file:// page with console.log events: in-memory `browse console`
returns the entries, but `.gstack/browse-console.log` is never created
on disk.

Regression introduced by 1a100a2a "fix: eliminate duplicate command
sets in chain, improve flush perf and type safety" — the flush refactor
switched from `Bun.write` to `fs.appendFileSync` and added the
`lastConsoleFlushed` cursor pattern alongside its network/dialog
siblings, but missed the matching `let` declaration. Tests don't
currently exercise flushBuffers, so the regression shipped silently.

Fix:
  - Declare `let lastConsoleFlushed = 0;` next to `lastNetworkFlushed`
    and `lastDialogFlushed` (browse/src/server.ts:327)
  - Add a source-level guard test
    (browse/test/server-flush-trackers.test.ts) that fails any future
    refactor that adds a fourth `last*Flushed` cursor without the
    matching declaration. Same pattern as terminal-agent.test.ts and
    dual-listener.test.ts — read source as text, assert invariant, no
    daemon required.

Test plan:
  - [x] New regression test fails on current main, passes with the fix
  - [x] `bun run build` clean
  - [x] Manual smoke: spawn daemon -> goto file:// page with
        console.log -> wait 4s -> .gstack/browse-console.log now
        exists with the expected entries (163 bytes vs zero before)

* fix(browse): per-process state-file temp path to fix concurrent-write ENOENT

The daemon writes `.gstack/browse.json` via the standard atomic-rename
pattern: `writeFileSync(tmp, …) → renameSync(tmp, stateFile)`. Four
sites in server.ts use this pattern (initial daemon-startup state at
:2002, /tunnel/start handler at :1479, BROWSE_TUNNEL=1 inline tunnel
update at :2083, BROWSE_TUNNEL_LOCAL_ONLY=1 update at :2113), and all
four hard-code the same temp filename `${stateFile}.tmp`.

Under concurrent writers the shared filename races on the rename:

    t0  Writer A: writeFileSync(stateFile + '.tmp', payloadA)
    t1  Writer B: writeFileSync(stateFile + '.tmp', payloadB)   // overwrites A
    t2  Writer A: renameSync(stateFile + '.tmp', stateFile)    // moves B's payload
    t3  Writer B: renameSync(stateFile + '.tmp', stateFile)    // ENOENT — file gone

Reproduced empirically with 15 concurrent CLIs against a fresh `.gstack/`:

    [browse] Failed to start: ENOENT: no such file or directory,
    rename '…/.gstack/browse.json.tmp' -> '…/.gstack/browse.json'

Pre-fix success rate: **0 / 15** under cold-start race.
Post-fix success rate: **15 / 15**, zero ENOENT.

Fix:
  - New `tmpStatePath()` helper (server.ts:333) returns
    `${stateFile}.tmp.${pid}.${randomBytes(4).toString('hex')}`
  - All 4 call sites use `tmpStatePath()` instead of the shared literal
  - Atomic rename still gives last-writer-wins semantics on the final
    state.json content; only behavior change is that concurrent writers
    no longer kill each other on the rename step

Source-level guard test (browse/test/server-tmp-state-path.test.ts)
locks two invariants: (1) no remaining `stateFile + '.tmp'` literals,
(2) every state-write `writeFileSync` call uses `tmpStatePath()`. Same
read-source-as-text pattern as terminal-agent.test.ts and
dual-listener.test.ts — no daemon required, runs in tier-1 free.

Test plan:
  - [x] Targeted source-level guard test passes (3 / 0)
  - [x] `bun run build` clean
  - [x] Live regression: 15 concurrent CLIs against cold state →
        15 / 15 healthy, 0 ENOENT (vs 0 / 15 pre-fix)
  - [x] No `.tmp.*` orphans left behind after rename succeeds
  - [x] Related test cluster (server-auth, dual-listener, cdp-mutex,
        findport) — same pre-existing flakes as `main`, no new
        regressions introduced

* fix(browse): clear refs when iframe auto-detaches in getActiveFrameOrPage

Asymmetric cleanup between two equivalent staleness conditions:

  onMainFrameNavigated()  →  clearRefs() + activeFrame = null  ✓
  getActiveFrameOrPage()  →  activeFrame = null  (refs NOT cleared)  ✗

Both paths see the same staleness condition — refs were captured
against a frame that no longer exists. The main-frame path correctly
clears both pieces of state. The iframe-detach path nulls the frame
but leaves the refMap intact.

The lazy click-time check in `resolveRef` (tab-session.ts:97) partially
saves us — `entry.locator.count()` on a detached-frame locator throws
or returns 0, so the click errors out as "Ref X is stale". But the
user has no signal that frame context silently changed underfoot: the
next `snapshot` runs against `this.page` (main) while old iframe refs
still litter `refMap` with the same role+name keys. New refs collide
with stale ones, the resolver picks one at random, the user clicks
the wrong element.

TODOS.md line 816-820 documents "Detached frame auto-recovery" as a
shipped iframe-support feature in v0.12.1.0. This restores the
documented intent — the recovery should leave the session in a clean
state, not a half-cleared one.

Fix: 1 line — add `this.clearRefs()` next to `this.activeFrame = null`
inside the if-branch.

Test plan:
  - [x] New regression test: 4/4 pass
        - refs cleared when getActiveFrameOrPage detects detached iframe
        - refs preserved when active frame is still attached (no regression)
        - refs preserved when no frame set (page-level path untouched)
        - matches onMainFrameNavigated symmetry — both paths reach the
          same clean end state
  - [x] `bun run build` clean

* fix(codex): resolve python for JSON parser

* fix: add fail-fast probe for base branch in ship step 12

* fix(plan-devex-review): remove contradictory plan-mode handshake

* fix(design): honor Retry-After header in variants 429 handler

Closes #1244.

The 429 handler in `generateVariant` discarded the `Retry-After` response
header and fell straight through to a local exponential schedule (2s/4s/8s).
In image-generation batches, that burns retry attempts inside the provider's
cooldown window and the request never recovers.

Now we parse `Retry-After` per RFC 7231 — both delta-seconds (`Retry-After: 5`)
and HTTP-date (`Retry-After: Fri, 31 Dec 1999 23:59:59 GMT`). Honored waits
are capped at 60s to bound stalls from hostile or buggy headers. Delta-seconds
are validated as digits-only (rejects `2abc`). When `Retry-After` is honored
(including 0 / past-date "retry now"), the next iteration's leading exponential
sleep is skipped so we don't double-wait. Invalid or missing headers fall
through to the existing exponential schedule unchanged.

Behavior matrix:

| Header                          | Behavior                                  |
|---------------------------------|-------------------------------------------|
| Retry-After: 5                  | wait 5s, skip leading on next attempt     |
| Retry-After: 999999             | capped to 60s, skip leading               |
| Retry-After: 2abc               | invalid, fall through to exponential      |
| Retry-After: 0                  | wait 0, skip leading (retry immediately)  |
| Retry-After: <past HTTP-date>   | wait 0, skip leading                      |
| Retry-After: <future date>      | wait diff capped at 60s, skip leading     |
| no header                       | fall through to existing exponential      |

`generateVariant` now accepts an optional `fetchFn` parameter (defaults to
`globalThis.fetch`) so tests can inject a stub. Production call sites are
unchanged.

Tests cover the five behavior buckets above, asserting both the 1st-to-2nd
call timing gap and call counts. All five pass in ~8s.

* fix(docs): correct per-skill symlink removal snippet in README uninstall

Closes #1130.

The manual-uninstall fallback in `## Uninstall` → `### Option 2` used
`find ~/.claude/skills -maxdepth 1 -type l`, which finds nothing on real
installs. Each `~/.claude/skills/<name>/` is a real directory, and only
`<name>/SKILL.md` inside it is a symlink into `gstack/`. The find never
matched, so the snippet silently removed nothing.

Replace with a directory walk that inspects each `<name>/SKILL.md`:

  find ~/.claude/skills -mindepth 1 -maxdepth 1 -type d ! -name gstack
  → check $dir/SKILL.md is a symlink → readlink it
  → if target is gstack/* or */gstack/*: rm -f the link, rmdir the dir
    (only if empty — preserves any user-added files)

Excludes the top-level `gstack/` dir from the walk; that's removed by
step 3 of the same uninstall block.

`bin/gstack-uninstall` (the script-mode path) already handles the layout
correctly via its own walk; only this manual fallback needed updating.

* fix(gemini-adapter): detect new ~/.gemini/oauth_creds.json auth path

gemini-cli >=0.30 stores OAuth credentials at ~/.gemini/oauth_creds.json
instead of the legacy ~/.config/gemini/ directory. The benchmark adapter's
availability check now succeeds for users on recent gemini-cli releases
who have authenticated via interactive login.

Both paths are accepted so users on older versions still work.

* fix(browser): add --no-sandbox for root user on Linux/WSL2

Chromium's sandbox can't initialize when running as root on Linux,
causing an immediate exit. Extend the existing CI/CONTAINER check to
also cover this case, keeping the Windows-safe `typeof getuid` guard.

* security: pass cwd to git via execFileSync, not interpolation through /bin/sh

`bin/gstack-memory-ingest.ts:632-643` ran `execSync(\`git -C ${JSON.stringify(cwd)}
remote get-url origin 2>/dev/null\`, ...)`. JSON.stringify escapes `"` and `\`
but not `$` or backticks, so a `cwd` of `"$(touch /tmp/marker)"` survived JSON
quoting and detonated under /bin/sh's command-substitution-inside-double-quotes.

`cwd` originates from transcript JSONL records under
`~/.claude/projects/<encoded-cwd>/<uuid>.jsonl` and
`~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl`. The walker grabs the first
`.cwd` it sees per session. That's an untrusted surface in the gstack threat
model — the L1-L6 sidebar security stack exists exactly because agent
transcripts can carry attacker-influenced text. Two pivots above the local
same-uid bar: (a) prompt-injection appending `cwd="$(...)"` to the active
session log turns the next /sync-gbrain run into RCE under the user's uid;
(b) cross-machine transcript share (a colleague's `.claude/projects` snippet
untar'd into HOME, a documented gbrain dogfooding shape) → RCE on first sync.

Fix swaps the one execSync for `execFileSync("git", ["-C", cwd, "remote",
"get-url", "origin"], ...)`. No shell, argv passed directly to git. The same
module already uses execFileSync for `gbrainAvailable()` (line 762 pre-patch)
and `gbrainPutPage()` (line 816 pre-patch) — this single execSync was the
outlier.

Test: `gstack-memory-ingest security: untrusted cwd cannot trigger shell
substitution` plants a Claude-Code-shaped JSONL with cwd=`$(touch <marker>)`
and asserts the marker file is not created after `--incremental --quiet`.
Negative control: with the patch reverted, the test fails (marker created);
with the patch applied, it passes (18/18 in test/gstack-memory-ingest.test.ts).

* security: gate domain-skill auto-promote on classifier_score > 0

`browse/src/domain-skill-commands.ts:140` (handleSave) writes
`classifier_score: 0` with the comment "L4 deferred to load-time / sidebar-agent
fills this in on first prompt-injection load." But CLAUDE.md "Sidebar
architecture" documents that sidebar-agent.ts was ripped, and grep for
recordSkillUse + classifierFlagged callers across browse/src/ returns zero hits
outside the module under test.

Net effect: every quarantined skill that survives three benign uses without
flag (`recordSkillUse(... , classifierFlagged: false)` x3) auto-promotes to
`active` and lands in prompt context wrapped as UNTRUSTED on every subsequent
visit to that host. The L4 score that was supposed to gate the promotion was
never written — the production save path puts 0 on disk and nothing later
updates it.

Threat model: a domain-skill body authored by an agent under the influence of
a poisoned page (the new `gstackInjectToTerminal` PTY path runs no L1-L3
either) would lose its auto-promote barrier after three uses. The exploit
isn't single-step but the bar is exactly N=3 prompt-injection-shaped uses on
a hostile page, which is well within reach.

Fix adds a single condition to the auto-promote gate in `recordSkillUse`:

    if (state === 'quarantined' && useCount >= PROMOTE_THRESHOLD &&
        flagCount === 0 && current.classifier_score > 0) {
      state = 'active';
    }

`classifier_score` is set once at writeSkill and never updated. Production
saves it as 0 (handleSave), so the gate stays closed; existing tests that
explicitly pass `classifierScore: 0.1` still auto-promote (the auto-promote
path is preserved for the day L4 is rewired).

Manual promotion via `domain-skill promote-to-global` is unaffected (it goes
through `promoteToGlobal` which has its own state-machine guard at line 337+).

Test: new regression case `does NOT auto-promote when classifier_score is 0
(production handleSave shape)` plants a skill with classifierScore=0 (matches
domain-skill-commands.ts:140), runs three uses without flag, asserts the skill
stays quarantined and readSkill returns null. Negative control: revert the
patch, the test fails with `Received: "active"`. With the patch: 15/15 pass.

* test(codex): live flag-semantics smoke for codex exec resume

Closes #1270's regex-only test gap. PR #1270 asserted that codex/SKILL.md's
`codex exec resume` invocation drops -C/-s and uses sandbox_mode config.
That regex catches the skill template regressing, but not codex CLI itself
flipping flag semantics again.

This test probes `codex exec resume --help` and asserts the surface gstack
relies on: -c/sandbox_mode is accepted, top-level -C is absent. Skips
silently when codex isn't on PATH, so dev machines without codex installed
never see it fail.

* chore: regen SKILL.md after fix wave

One regen commit at the end of the merge wave per the plan. plan-devex-review
loses the contradictory plan-mode handshake (#1333). review/SKILL.md picks up
the Verification Mode + UNVERIFIABLE classification additions that #1302
authored against ship/SKILL.md (same resolver shared between ship and review
modes).

* fix(server.ts): keep fs.writeFileSync for state-file writes

#1308's writeSecureFile wrapper added Windows icacls hardening for the
4 state-file write sites in server.ts, but #1310's regression test grep's
for fs.writeFileSync(tmpStatePath()) calls. The two changes are technically
compatible only if the test relaxes — keeping the test strict (the safer
choice for catching regressions on the cold-start race) means the 4 state-
file sites stay on fs.writeFileSync(..., { mode: 0o600 }).

POSIX 0o600 hardening is preserved on those 4 sites. Windows icacls
hardening still applies to all the other writeSecureFile call sites
#1308 added (auth.json, mkdirSecure, etc.).

Also refreshes golden baselines after #1302 / port + minor wording tweak
in scripts/resolvers/review.ts to keep gen-skill-docs.test.ts assertion
'Cite the specific file' satisfied.

* v1.30.0.0: fix wave — 21 community PRs + 2 closing fixes for Windows + codex CI gaps

Headline release. Browse stops dropping console logs, cold-start race
fixed, codex resume works without python3, Windows hardening (icacls +
Bun.which + bash.exe wrap), ship gate gets VAS-449 remediation, two
closing fixes that put icacls/Bun.which/codex flag semantics under CI.

* test(domain-skills): cover #1369 classifier_score=0 quarantine + score>0 promote path

The pre-existing T6 test seeded skills via writeSkill (which defaults
classifier_score to 0 until L4 is rewired) and then expected 3 uses to
auto-promote. PR #1369 added `current.classifier_score > 0` to the gate
specifically to block that path — a quarantined skill written under the
influence of a poisoned page would otherwise auto-promote after three
benign uses.

Updated test asserts both halves of the new contract:
- classifier_score=0 + 3 uses → stays quarantined (the security guarantee)
- classifier_score>0 + 3 more uses → promotes to active (unblock path)

Catches both regressions: the gate going away (would re-allow the bypass)
and the unblock path breaking (would silently quarantine all skills
forever once L4 is rewired).

Garry Tan 0570ef93a5 v1.24.0.0 feat: cross-platform hardening — curated Windows lane + Bun.which resolver + path-portability helper (#1252)
* feat(paths): bin/gstack-paths helper + migrate 8 skills off inline state-root chains

New bin/gstack-paths emits GSTACK_STATE_ROOT, PLAN_ROOT, TMP_ROOT exports for
skill bash blocks to source via eval. Honors GSTACK_HOME → CLAUDE_PLUGIN_DATA →
$HOME/.gstack → .gstack (and parallel chains for plan/tmp roots) so skills work
the same in plugin installs, global installs, and CI containers without HOME.

Eight skills migrate off inline ${CLAUDE_PLUGIN_DATA:-...} or ${GSTACK_HOME:-...}
chains: careful, freeze, guard, unfreeze, investigate, context-save,
context-restore, learn, office-hours, plan-tune, codex. Resolved values are
identical, so existing tests cover correctness; the win is consolidating 11
copy-pasted fallback chains behind one helper.

codex/SKILL.md.tmpl gets a new Step 0.6 Resolve portable roots that sources
gstack-paths once, then replaces hardcoded ~/.claude/plans/*.md and
/tmp/codex-*-XXXXXX.txt with "$PLAN_ROOT"/*.md and "$TMP_ROOT/codex-*-XXXXXX.txt".

Hardening direction credited to the McGluut/gstack fork; this is upstream's
factoring of the per-skill chain the fork inlined.

Tests: test/gstack-paths.test.ts covers all three fallback chains with 8 unit
tests (HOME unset, CLAUDE_PLUGIN_DATA set, GSTACK_HOME wins, etc).

* feat(claude-bin): Bun.which wrapper for cross-platform claude resolution

Replaces 75 LOC of fork-side reimplementation (PATH parsing, Windows PATHEXT,
case-insensitive Path/PATH, X_OK) with a thin wrapper around Bun.which() — the
runtime built-in that already does all of it. New file is ~70 LOC including
the override + arg-prefix logic the runtime doesn't cover.

Override branch fixed: GSTACK_CLAUDE_BIN=wsl now resolves through Bun.which()
just like a bare claude lookup would. The McGluut fork's claude-bin.ts only
handled absolute-path overrides; bare commands silently returned null. Passing
the override value through Bun.which fixes the documented use case for free.

Five hardcoded claude spawn sites rewired through resolveClaudeCommand:
  - browse/src/security-classifier.ts:396 — version probe
  - browse/src/security-classifier.ts:496 — Haiku transcript classifier
  - scripts/preflight-agent-sdk.ts — preflight binary pinning
  - test/helpers/providers/claude.ts — LLM judge availability + run
  - test/helpers/agent-sdk-runner.ts — SDK harness binary resolver
All retain their existing degrade-on-missing semantics.

Tests: browse/test/claude-bin.test.ts has 9 unit tests including the
override-PATH-resolution case the fork's version got wrong.

* docs+test: AGENTS.md/docs/skills.md inventory sync + private-path leak detector

Inventory sync (codex-flagged drift):
- /debug → /investigate (skill renamed in v1.0.1.0)
- AGENTS.md grows from 21 to 40+ skills, organized by category (plan reviews,
  implementation, release, operational, browser, safety)
- docs/skills.md gains 11 missing entries: /plan-devex-review, /devex-review,
  /plan-tune, /context-save, /context-restore, /health, /landing-report,
  /benchmark-models, /pair-agent, /setup-gbrain, /make-pdf
- Stale "<5s bun test" claim dropped — slim-preamble harness + new tests means
  no realistic universal claim to make
- Adds explicit "Mac + Linux full, curated Windows lane" platform statement +
  "Git Bash / MSYS today, native PowerShell future" install note

New invariants in test/skill-validation.test.ts (~80 LOC):
- Private-path leak detector scans every SKILL.md / SKILL.md.tmpl for known
  maintainer-only filenames (coordination-board.md, SEEKING_LOG.md,
  RATIONAL_SUBJECT.md, VALUE_SIGNAL_LOOP.md, C:\LLM Playground\go).
  Adapted from the McGluut fork's skill-contract-audit.ts; we don't take
  the script wholesale because most of its checks are already covered by
  test/gen-skill-docs.test.ts:1668-2074 and test/skill-validation.test.ts:1419
  — only the private-path scan and doc-inventory cross-check are new.
- Doc-inventory cross-check: every skill directory with a SKILL.md.tmpl must
  appear in both AGENTS.md and docs/skills.md. Catches the inventory drift
  this commit is fixing — without this test it would just drift again.

* feat(windows): curated windows-free-tests CI job + test-free-shards curation

Codex's v1.18.0.0 review flagged that a windows-latest matrix entry on the
existing Linux-container evals.yml workflow can't work as a drop-in, and that
the free test suite has POSIX-bound dependencies a sharded runner doesn't fix
on its own. This commit takes McGluut's test-free-shards.ts (190 LOC), adds a
Windows-fragility scan, and runs the curated subset on a separate non-container
windows-latest job.

scripts/test-free-shards.ts:
- Enumeration + paid-eval filtering + stable-hash sharding (FNV-1a). Adapted
  from McGluut/gstack fork.
- Upstream-original: --windows-only filter scans each test's content for
  POSIX-bound patterns: hardcoded /bin/sh, spawn('sh', ...), bash -c, raw
  /tmp/, chmod, xargs, which claude. Files matching are excluded with the
  reason logged. Currently filters 25 of 128 free tests; remaining 103 run
  on windows-latest.

.github/workflows/windows-free-tests.yml:
- Separate non-container job (NOT a matrix entry on evals.yml). Runs:
    bun run test:windows                       # curated subset
    bun test browse/test/claude-bin.test.ts    # PATHEXT+overrides on Windows
    bun test test/gstack-paths.test.ts         # state-root resolution

package.json: new test:free + test:windows scripts.

Honest about scope (codex-flagged): this does NOT make the full free suite
Windows-safe. The 25 excluded tests need POSIX-only surfaces ported off shell
primitives (test/ship-version-sync.test.ts:72 hardcodes /bin/bash, etc).
Tracked as a P4 follow-up TODO. Full Windows parity is the next wave; this
release ships the curated lane.

Tests: test/test-free-shards.test.ts has 14 unit tests covering enumeration,
paid-eval filtering, Windows-fragility detection (POSIX patterns + safe code),
and stable sharding determinism.

* chore(release): v1.20.0.0 — cross-platform hardening, curated Windows lane

Cross-platform hardening. Mac + Linux full, curated Windows lane added.

Workspace-aware queue at ship time:
- v1.17.0.0 claimed by garrytan/setup-gbrain-run (PR #1234)
- v1.19.0.0 claimed by garrytan/browserharness (PR #1233)
- This branch claims v1.20.0.0 (next available slot)

(Initially bumped to v1.18.0.0 during plan-mode implementation; rebumped to
v1.20.0.0 at /ship time when gstack-next-version detected the queue had moved.)

Headline numbers (full release-note in CHANGELOG.md):
- 2 new shared resolvers: bin/gstack-paths (61 LOC), browse/src/claude-bin.ts (73 LOC)
- 8 skills migrated off inline state-root chains
- 5 hardcoded claude spawn sites rewired through the shared resolver
- 75 LOC of fork-side reimplementation replaced by Bun.which()
- 103 of 128 free tests run on windows-latest (curated, ~80%)
- +31 new unit tests + 3 new invariants
- AGENTS.md inventory grows from 21 to 40+ skills

* fix(windows-ci): configure git identity + extend Windows-fragility curation

First windows-free-tests CI run surfaced 34 failures across two patterns:

1. Tests that init a temp git repo via execSync('git commit ...') — Windows
   runner has no default git user.email/user.name, so the commit fails.
   Fix: add a "Configure git identity" step to .github/workflows/windows-free-tests.yml
   that sets a CI-only identity globally.

2. Tests that use POSIX-only APIs unconditionally:
   - file-mode bitmask checks (`stat.mode & 0o600`, `mode & 0o111`) — Windows
     fakes mode bits and these assertions don't compose
   - hardcoded forward-slash path assertions (`file.endsWith('/tab-42.json')`)
     — Windows path separators are '\\'
   Fix: extend WINDOWS_FRAGILE_PATTERNS in scripts/test-free-shards.ts to
   detect both. 8 additional tests now excluded from the curated Windows
   subset with logged reasons:
     - browse/test/security-review-flow.test.ts (file mode)
     - browse/test/security-sidepanel-dom.test.ts (forward-slash path)
     - browse/test/url-validation.test.ts (forward-slash path)
     - test/gbrain-repo-policy.test.ts (file mode)
     - test/relink.test.ts (file mode)
     - test/skill-validation.test.ts (file mode — single assertion at :934)
     - test/team-mode.test.ts (file mode — also kills its 30 git-init beforeEach failures)
     - test/upgrade-migration-v1.test.ts (file mode)

Curated Windows subset: 103 → 95 tests (still ~74% of free suite). All
14 test-free-shards unit tests still pass.

* fix(windows-ci): enforce LF + build server-node.mjs in CI

Second round of windows-free-tests fixes after the first push. Curated subset
went from 386/34 to 58/4 fails. Remaining 4 fails + 1 error trace to two root
causes:

1. Line-ending sensitivity. Windows checkout with core.autocrlf=true converts
   .md/.tmpl files to CRLF. Tests that parse YAML frontmatter with
   `/^---\n([\\s\\S]+?)\n---/` then return zero matches — skill-collision-
   sentinel.test.ts:120 enumerated 0 skills on Windows, cascading into 3
   downstream test failures (sanity, KNOWN_COLLISIONS, /checkpoint resolved).

   Fix: add .gitattributes that pins LF for .md/.tmpl/.yml/.json/.toml/.sh/
   .ts/.tsx/.js/.mjs/.cjs/.bash. Root-cause fix; prevents future similar
   tests from hitting the same trap. Also keeps bash scripts LF on Linux
   runners (CRLF in shebangs produces "bad interpreter" errors).

2. Module-level Windows assertion in browse/src/cli.ts:82 throws if
   browse/dist/server-node.mjs is missing. Any test that transitively loads
   cli.ts (e.g., browse/test/tab-isolation.test.ts via shard mate imports)
   then fails to even start. server-node.mjs is generated by bash
   browse/scripts/build-node-server.sh, which `bun run build` calls but
   `bun install` does not.

   Fix: add a "Build server-node.mjs" step to .github/workflows/
   windows-free-tests.yml. Calls only the node-server build script, not
   full `bun run build` — we don't need the compiled binaries for tests
   and the full build is slow.

Expected: skill-collision-sentinel goes 0→3 pass (sanity, KNOWN_COLLISIONS,
/checkpoint resolved). tab-isolation's "unhandled error between tests"
disappears. Remaining tests should be green.

* fix(windows-ci): platform-aware claude-bin test + curate bin/ shebang spawns

Round 3 of windows-free-tests fixes. Round 2 (LF gitattributes + server-node.mjs
build) cleared shard 1 entirely (skill-collision-sentinel and tab-isolation
green). Shard 2 surfaced two more issues:

1. browse/test/claude-bin.test.ts:50 — the "PATH-resolvable override" test
   creates a fake binary 'fake-claude-cli' (no extension) and expects
   Bun.which to find it. On Windows, Bun.which probes PATHEXT extensions
   (.cmd, .exe, .bat) — a bare-name file is not discoverable. Production
   behavior is correct; the test was Mac/Linux-shaped.

   Fix: branch on process.platform. On Windows, write 'fake-claude-cli.cmd'
   with a Windows batch payload instead of a POSIX shebang script.

2. test/gstack-question-log.test.ts (and 18 sibling tests) — spawn a bash
   shebang script via spawnSync(BIN, args). Git Bash on Windows can run
   `bash /path/to/script` but spawnSync invokes CreateProcess directly,
   which doesn't parse #!/usr/bin/env bash. All these tests are
   Windows-fragile and can't run as-is.

   Fix: extend WINDOWS_FRAGILE_PATTERNS with `path.join(.., 'bin', ..)`
   detector. Curates 19 additional tests (benchmark-cli, brain-sync,
   builder-profile, explain-level-config, gbrain-*, gstack-question-*,
   hook-scripts, learnings, plan-tune, review-log, secret-sink-harness,
   taste-engine, telemetry, timeline, uninstall).

Curated Windows subset: 95 → 76 tests (~59% of free suite). Still
meaningful Windows coverage. The 52 excluded tests are tracked as a
follow-up TODO for full Windows parity (shebang-bin spawns + POSIX file
modes + raw /tmp/ etc).

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

* fix(windows-ci): curate Playwright-launching tests

Round 4 of windows-free-tests fixes. Round 3 cleared shard 2 except for
browse/test/batch.test.ts:35 which calls `await bm.launch()` and triggers
Playwright Chromium launch. The windows-latest runner doesn't have
Chromium installed (browser bring-up is a separate concern, tracked by
PR #1238 windows-pty-bun-pty-fix).

Fix: extend WINDOWS_FRAGILE_PATTERNS with `await \\w+\\.launch\\(` matcher.
Catches batch.test.ts plus 7 sibling tests (commands, compare-board,
content-security, handoff, security-live-playwright, security-sidepanel-dom,
snapshot — most already excluded by other patterns).

Curated Windows subset: 76 → 72 tests (~56% of free suite). Net curation
across all 4 rounds: 56 of 128 free tests excluded, each with a logged
reason. The 56 excluded fall into 6 buckets — POSIX shells, raw /tmp/,
chmod/xargs, file mode bitmasks, forward-slash path assertions, bin/
shebang spawns, and Playwright launches — all tracked as a P4 follow-up
TODO for full Windows parity.

* fix(windows-ci): catch destructured join() bin-spawns + browse server tests

Round 5 of windows-free-tests fixes. Round 4 caught Playwright launchers
but two more failure shapes appeared in shard 5:

1. test/diff-scope.test.ts uses `import { join }` (destructured) and
   `join(import.meta.dir, '..', 'bin', 'gstack-diff-scope')`. My round-3
   pattern only matched `path.join(...)` — the destructured form slipped
   through. Tightened the pattern to match the literal `, 'bin', '<name>'`
   path-segment shape regardless of whether it's `path.join` or `join`
   directly.

2. browse/test/sidebar-integration.test.ts spawns the browse server via
   `spawn(['bun', 'run', server.ts])` with BROWSE_HEADLESS_SKIP=1. The
   Bun-run-server.ts path is the same Playwright-on-Windows broken path
   that the windows-free-tests job intentionally avoids — the server-node.mjs
   route only kicks in for the compiled binary, not direct Bun runs of the
   TypeScript source. Added a BROWSE_HEADLESS_SKIP / spawn-bun-run pattern.

Curated Windows subset: 72 → 73 tests (~57% of free suite). Net up by 1
because the tightened bin pattern released one test that was a false
positive in the loose `path\\.join` form.

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

* fix(windows-ci): broaden bin/ pattern to match path.join(ROOT, 'bin')

Round 6. Round 5 tightened the bin/ pattern to require a script-name segment
after 'bin', which inadvertently released test/brain-sync.test.ts that uses:

  const BIN = path.join(ROOT, 'bin');
  const full = bin.startsWith('/') ? bin : path.join(BIN, bin);

The 'bin' segment is the LAST argument to path.join — there's no literal
script name to match. The earlier looser pattern caught this; round 5
broke that.

Fix: revert to `,\\s*['"]bin['"]\\s*[,)]` which matches both forms:
  - `, 'bin', 'script-name')`  (path.join with name) — typical
  - `, 'bin')`                  (path.join ending at bin) — brain-sync style

Curated subset: 73 → 66 tests (~52% of free suite). The 7 additional
exclusions are all bin-script tests that were misclassified by the round-5
tightening.

* fix(find-browse): guard main() with import.meta.main

Round 7 of windows-free-tests fixes (and a genuine bug fix beyond Windows).

browse/src/find-browse.ts called main() unconditionally at module load.
main() calls process.exit(1) when no compiled `browse` binary exists at the
known install paths. Any test that imports `locateBinary` from this module
then exits the entire test process before any tests run.

This affected the windows-free-tests CI lane because the runner intentionally
doesn't compile the browse binary (only server-node.mjs is built — full
binary compilation is slow and not needed for the curated subset). It would
also affect any Mac/Linux contributor who runs tests in a fresh checkout
before running ./setup, though the symptom is rarer there.

Fix: wrap `main()` in `if (import.meta.main) { main() }`. The CLI invocation
(via the find-browse binary or `bun run browse/src/find-browse.ts`) still
runs main() and emits the path. Imports get only the named exports.

Verified locally:
  - `bun run browse/src/find-browse.ts` still prints the binary path.
  - `import { locateBinary } from '...'` no longer exits the process.
  - `bun test browse/test/find-browse.test.ts` passes 4/4 (was crashing
    at module load).

* fix(windows-ci): pin LF on extensionless executables (setup, bin/*, scripts/*)

Round 8 of windows-free-tests fixes. Round 7 cleared find-browse + most
shards; one fail left in shard 7:

  test/setup-codesign.test.ts > codesign shell snippet is syntactically valid
  expect(received).toBeTruthy() — match was null

The test extracts a bash codesign block from the `setup` file via a
\\n-anchored regex, then syntax-checks it with `bash -n`. On Windows the
regex returned null because the `setup` file was checked out with CRLF
endings — my round-2 .gitattributes only covered files matched by extension
patterns (*.md, *.sh, *.ts) and `setup` is extensionless.

Fix: extend .gitattributes with explicit rules for extensionless executables:
  setup        text eol=lf
  bin/*        text eol=lf
  **/scripts/* text eol=lf

This also LF-pins all the bash bin/ scripts (gstack-paths, gstack-slug,
gstack-codex-probe, ...) which would otherwise break with "bad interpreter"
errors on Linux if a Windows contributor accidentally committed CRLF
versions. Defense in depth.

Verified locally: `git check-attr eol setup bin/gstack-paths` reports
`eol: lf` for both. Renormalized via `git add --renormalize` so any
already-LF files in the repo stay LF after the .gitattributes change.

* fix(windows-ci): gen:skill-docs in workflow + known-bad list for env-specific tests

Round 9 of windows-free-tests fixes. Round 8 cleared shard 7; shard 8
surfaced 4 fails:

1+2. test/gen-skill-docs.test.ts golden-file regression for Codex + Factory
   ship skills failed with ENOENT on `.agents/skills/gstack-ship/SKILL.md`
   and `.factory/skills/gstack-ship/SKILL.md`. These are gitignored
   gen-skill-docs outputs that the Mac/Linux CI workflows already
   regenerate elsewhere — the windows-free-tests lane never did.

   Fix: add `bun run gen:skill-docs --host all` step to
   windows-free-tests.yml after `bun install`.

3. test/host-config.test.ts:377 "detect finds claude" asserts the `claude`
   binary is on PATH. True when running inside Claude Code; false on a
   bare CI runner.

4. browse/test/findport.test.ts:117 asserts Bun.serve.stop() is
   fire-and-forget (returns undefined). Bun's Windows behavior for this
   polyfill differs; the assertion is Bun-on-non-Windows-specific.

Both 3 and 4 are environment/runtime-specific failures that don't fit a
regex pattern. Added a KNOWN_WINDOWS_INCOMPATIBLE explicit list to
scripts/test-free-shards.ts so they're curated by exact path, with a
reason string. The list is for cases where pattern matching can't infer
the failure shape from the source file alone.

Curated subset: 66 → 64 tests (~50% of free suite). 14 unit tests in
test/test-free-shards.test.ts still pass.

* fix(windows-ci): curate pre-existing breakage from v1.14.0.0 sidebar refactor

Round 10 of windows-free-tests fixes. Round 9 cleared shards 7+8; shard 9
surfaced ENOENT for browse/src/sidebar-agent.ts. That file was DELETED in
v1.14.0.0 (sidebar REPL refactor — sidebar-agent.ts and the chat queue
path were ripped in favor of the interactive xterm.js PTY). 10 security
tests still reference it via top-level fs.readFileSync and fail on import.

Verified locally: `bun test browse/test/security-source-contracts.test.ts`
on this branch reports 0 pass, 1 fail, 1 error. Mac/Linux CI exits 0
because Bun reports module-load failures as "error" not "fail" and the
exit code is 0; Windows CI exits 1 (stricter). Same pre-existing
breakage on every platform — just only visible in shard 9 of the
Windows lane.

Fix: add WINDOWS_FRAGILE_PATTERNS entry matching `sidebar-agent.ts` /
`src/sidebar-agent` references. Curates browse/test/sidebar-ux.test.ts
(other 9 likely caught by paid-eval filter or earlier patterns).

Tracked as a follow-up TODO: update or delete the 10 security tests that
reference deleted source. Out of scope for v1.20.0.0 portability wave.

Curated subset: 64 → 63 tests (~49% of free suite).

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

* fix(windows-ci): broaden sidebar-agent.ts pattern to catch all references

* fix(windows-ci): catch ./bin/<name> direct path spawns

* fix(windows-ci): scope Windows job to v1.20.0.0 new portability work

12 rounds of curation revealed that gstack has a long tail of tests with
environment-specific assumptions (POSIX paths, /tmp, mode bits, bash
spawns, deleted v1.14 sidebar refs, HOME=unset guards, Bun polyfill
specifics). Each round of pattern-matching curation caught 1-2 new
buckets but kept surfacing more.

Honest scope for v1.20.0.0: this PR delivers two new portability
primitives (bin/gstack-paths + browse/src/claude-bin.ts). The Windows
CI job should verify those primitives work on Windows. Full-suite
Windows parity is a P4 follow-up that requires touching many tests
that aren't part of this PR's scope.

Change: windows-free-tests.yml now runs:
  bun test test/gstack-paths.test.ts \\
           browse/test/claude-bin.test.ts \\
           test/test-free-shards.test.ts

That's 31 tests targeting exactly the new code paths shipped here.
The release-note headline ("curated Windows lane added") becomes
truthful when this passes — we have a real Windows CI gate on the
new portability work, not a rebadged failure-tolerant attempt at the
full suite.

Retained: scripts/test-free-shards.ts curation logic (informational
output via `--list`, useful for future expansion of the Windows lane
when contributors port specific tests).

* fix(test): invoke bin/gstack-paths via bash (Windows shebang fix)

Round 13 of windows-free-tests fixes. Round 12 (scope pivot) revealed all
8 gstack-paths tests fail on Windows because the test invokes the bash
shebang script directly:

  spawnSync(BIN, [])  # BIN = path.join(ROOT, 'bin', 'gstack-paths')

Windows CreateProcess can't parse `#!/usr/bin/env bash` from the file.
The script never runs on Windows via this invocation path.

Fix: change to `spawnSync('bash', [BIN], ...)`. This matches production
usage — the script is sourced from inside skill bash blocks via
`eval "$(~/.claude/skills/gstack/bin/gstack-paths)"`, where bash is
always the executor. Mac/Linux behavior is identical (bash invocation
of a bash script).

Verified locally: 8/8 tests still pass on macOS.

* chore(release): rebump v1.20.0.0 → v1.22.0.0 (queue drift)

Version-gate workflow rejected v1.20.0.0 because the queue moved during
the windows-free-tests fix loop:

  v1.16.0.0 → garrytan/gbrowser-unleashed (PR #1253)  [new since last bump]
  v1.17.0.0 → garrytan/setup-gbrain-run    (PR #1234)
  v1.19.0.0 → garrytan/browserharness       (PR #1233)
  v1.21.1.0 → garrytan/pty-plan-mode-e2e    (PR #1255)  [new since last bump]

Two new sibling PRs landed slot claims while we iterated on Windows.
Next free MINOR slot is v1.22.0.0.

Updated VERSION, package.json, CHANGELOG header + body. Also pushing the
round-13 windows-fix in parallel (test invokes bin/gstack-paths via bash
to handle Windows shebang).

* fix(test): clear USERPROFILE alongside HOME (Git Bash auto-populates HOME)

Final Windows fix. 29/31 pass; 2 fail in gstack-paths HOME-unset tests:

  (fail) CWD fallback when HOME also unset (container env)
  (fail) PLAN_ROOT chain: GSTACK_PLAN_DIR > CLAUDE_PLANS_DIR > HOME > CWD

Root cause: Git Bash on Windows auto-populates `HOME` from `USERPROFILE`
at shell startup if HOME is empty/unset. Passing `HOME: ''` to spawnSync
does set HOME='' for the child, but Git Bash overwrites it from
USERPROFILE during init, so the script sees `${HOME:-}` as non-empty
(C:\\Users\\runneradmin) and never reaches the CWD-fallback branch.

Fix: clear USERPROFILE='' too. On Linux/Mac it's a no-op (env var doesn't
exist in normal env); on Windows Git Bash it stops the HOME auto-populate.

* fix(test): skip HOME-unset assertions on Windows (Git Bash auto-populates)

29/31 → 31/31 expected on Windows. Final fix:

The 2 still-failing gstack-paths tests assert CWD-fallback behavior when
HOME is genuinely unset (Linux container scenario). On Windows Git Bash,
HOME gets auto-derived from USERPROFILE → HOMEDRIVE+HOMEPATH → /c/Users/<user>
during shell startup. Clearing all three of those env vars in the spawn
still results in HOME being non-empty by the time the script runs.

The bash script's CWD-fallback logic IS correct — it just isn't exercisable
through the Git Bash test surface. Skip those specific assertions on
Windows; they continue to verify on Linux/Mac.

This is the only platform-specific test guard introduced; it's narrowly
scoped to the unreachable code path, not a bypass of the real check.
