+21 ae8914af7e v1.67.0.0 fix: the tracker wave — XProtect self-heal, complete installs, brain-sync integrity, 31 community PRs credited (#2604)
* fix(test): host-config goldens self-provision .agents/.factory artifacts

Fixes #2532. The codex/factory golden tests read gitignored artifacts that
only gen-skill-docs.test.ts (serial tree-mutating phase) produces, so the
file failed in isolation and on clean clones (the #2536 "3 failures then 0"
symptom). beforeAll now generates a host's artifacts iff its ship SKILL.md
is missing — never overwriting existing ones, so stale artifacts still fail
the golden. The file is also classified TREE_MUTATING so its provisioning
runs in the serial window, not racing parallel readers.

Verified: full pass with .agents/ and .factory/ deleted (74/74 in isolation).

* fix(test): exempt the live repo tree from hermetic-wiring's operator-~/.claude ban

The skill-seeding tripwire asserted every seeded symlink target must NOT
start with ~/.claude — but on the default global-git install the repo
itself lives at ~/.claude/skills/gstack, so every CORRECT symlink (which
must resolve into the live repo tree, as the very next assertion requires)
carried the banned prefix. The test could never pass on a default install:
pristine v1.64.1.0 (c118e240) fails it in any worktree under
~/.claude/skills/ and passes elsewhere (verified 2026-08-15).

Exempt targets that realpath into the resolved repo ROOT before applying
the operatorClaude ban — realpath both sides so a symlinked HOME can't
dodge the tripwire. Genuine escapes (a target under ~/.claude but outside
the repo) still fail with the escape message.

* fix(gen-skill-docs): quote YAML inline scalars containing '...' (Bun strict parser breaks on bare ellipsis)

A bare ... inside a plain YAML scalar is a document-end marker that strict
YAML parsers (Bun.YAML among them) reject mid-scalar. catalog-trim truncation
appends '...' to any description whose lead exceeds 200 chars, so any
truncated description would generate a SKILL.md with unparseable frontmatter.
Add the ellipsis test to toYamlInlineScalar's needsQuote so such scalars are
emitted double-quoted, plus unit coverage for the quoting rules.

* fix(gen-skill-docs): throw when a template contains {{PREAMBLE}} twice

Hardens the #2508/#2362 class: a second {{PREAMBLE}} occurrence — even a
prose mention, which is exactly how spec/SKILL.md.tmpl re-expanded the full
~12K-token preamble mid-document — now fails generation with the template
path instead of silently shipping a doubled preamble. Pure exported guard
(assertSinglePreamble) called from resolvePlaceholders, unit-tested with the
original prose-mention shape.

* fix(test): classify catalog-trim.test.ts as tree-mutating

Discovered while landing the duplicate-{{PREAMBLE}} guard: importing
scripts/gen-skill-docs.ts executes its top-level body, which regenerates the
entire claude host (71 GENERATED files) at import time. catalog-trim.test.ts
does that import from a PARALLEL shard — the same read-during-regeneration
hazard class as #2532, invisible only because the regen is byte-identical on
a fresh tree. Move it to the serial tree-mutating window.

* fix(test): prepush hook test builds PATH with a POSIX-only separator

`test/redact-prepush-hook.test.ts` shadows `git` with a stub by prepending a
temp dir to PATH, built as `${stubDir}:${process.env.PATH}`. On Windows the
separator is `;`, so that produces one unparseable entry, the stub is never
found, and the REAL git runs — the diff succeeds, `gitStrict` never throws, and
the hook exits 0 where the test expects 1. It fails as a wrong assertion rather
than as a portability problem, which is what made it hard to place.

Replace it with a `prependPath` helper mirroring the one already in
test/gstack-brain-context-load.test.ts, which handles both platform details:
`path.delimiter`, and a case-insensitive lookup of the existing env key —
Windows commonly spells it `Path`, and adding a second `PATH` alongside an
inherited `Path` leaves the winner up to the spawn implementation.

On POSIX the helper resolves to `{ PATH: binDir + ":" + process.env.PATH }`,
byte-identical to the expression it replaces, so behaviour there is unchanged.

Fixing the separator alone does not make the test pass on Windows, and it
cannot: the premise is that a signal-killed child yields `spawnSync`
status === null, and Windows has no equivalent (a force-killed process reports
a non-zero exit code). The stub is also a `#!/bin/sh` file named `git`, which
Windows will not execute, since process creation resolves through PATHEXT and
ignores the shebang. A Windows variant would assert the non-zero-exit branch
instead — a different branch than the test name claims — so the test is gated
with test.skipIf(process.platform === "win32"), matching
test/session-runner-timeout.test.ts and test/setup-emoji-font.test.ts.

Windows before: 14 pass, 1 fail. After: 14 pass, 1 skip, 0 fail (3 consecutive
runs). Unchanged on POSIX, where it should still run and pass — worth
confirming in CI, since I can only verify the Windows half here.

* fix(artifacts): sync the decision store, which no allowlist glob matched

gstack-decision-log enqueues projects/<slug>/decisions.jsonl after every write,
but none of the 16 managed globs matched it, so compute_paths_to_stage rejected
every one at its "must match at least one allowlist glob" check.

The writer and the syncer disagreed silently: enabling artifacts sync backed up
learnings, plans, designs and timelines -- everything except the durable decision
ledger -- and nothing reported a miss, because a dropped path prints exactly what
a synced one does when the queue is otherwise empty.

Add the three decisions.* globs and class them artifact so they also sync in
artifacts-only mode.

The test reads the heredocs out of the script rather than executing it:
gstack-artifacts-init.test.ts drives the real script through #!/bin/bash shims and
a colon-separated PATH, so it cannot run on Windows -- the platform where the
companion slug bug bit.

* fix(windows): resolve the project slug natively when gstack-slug cannot spawn

bin/gstack-slug is a `#!/usr/bin/env bash` script with no file extension. Windows
honors neither the shebang nor PATHEXT for an explicit path, so spawnSync fails
ENOENT and resolveSlug returned its literal fallback, "unknown".

Every decision on the machine was therefore filed under
~/.gstack/projects/unknown/ -- one bucket shared by every project -- while the
bash-side Context Recovery preamble resolved the real slug, found no
decisions.active.json there, and skipped through a bare `if [ -f ... ]` with no
else.

Nothing failed. Both decision bins (log and search) missed identically, so writes
and searches stayed consistent with each other, and the only component that
resolved correctly was silent by design. Measured on one machine: 62 decisions
accumulated over 10 days and 170 skill runs, surfaced zero times.

shell:true is not the fix here, unlike #1731 -- cmd.exe cannot run a bash script
either. Nor is re-spawning through `bash`: on Windows that frequently resolves to
WSL, whose $HOME and /mnt/c paths yield a different slug AND a different cache
directory, trading one split store for another.

Instead, port gstack-slug's own three steps (cache -> git remote -> basename),
keeping its alphabet and its MSYS-form cache key so both paths agree. The
fallback is win32-gated, so POSIX behaviour is byte-identical.

Tests exercise the fallback on every platform (only the gating is win32-specific),
so POSIX CI catches a regression that would otherwise surface only on a Windows
user's disk, plus a static gate pinning the platform check.

* fix(security): guard brain-sync arithmetic against injected .brain-last-pull; sanitize _GBRAIN_HOST

Re-derived from PR #2588 under the generated-file screening rule (resolver
hunks taken; SKILL.md files regenerated, not accepted). A poisoned
.brain-last-pull could reach bash arithmetic ($(( ))) — a code-execution
vector from a writable state file; the timestamp is now validated numeric
before use. _GBRAIN_HOST from ~/.claude.json is clamped to hostname-safe
characters before echo. Ship goldens refreshed to the regenerated output.

* fix(sync): run gstack-brain-sync through bash, not cmd.exe, on Windows

The brain-sync stage failed on EVERY Windows run with "is not
recognized as an internal or external command", so /sync-gbrain always
reported ERR brain-sync among otherwise green stages.

#1731 gave these spawns shell: NEEDS_SHELL_ON_WINDOWS. That is correct
for the gbrain.cmd shim and does nothing here: shell:true routes through
cmd.exe, which resolves .cmd/.bat via PATHEXT but has no concept of a
shebang, so an extension-less bash script is rejected outright. A .cmd
shim needs a shell; a shebang script needs an interpreter. The two cases
look identical and are not.

The failure was quiet rather than loud. artifacts_sync_mode defaults to
pushing curated artifacts to git, so a Windows user's learnings piled up
uncommitted in ~/.gstack indefinitely while the sync report showed one
red line out of four.

New bashScriptInvocation() resolves Git for Windows' bash explicitly and
passes the script as argv[0]. It prefers Git bash over a bare `bash` on
PATH because WindowsApps ships a bash.exe that is the WSL launcher, which
would read C:\... as a Linux path; GSTACK_BASH overrides for unusual
installs; forward slashes because bash treats backslashes as escapes; and
it returns null when no bash exists so the stage says so plainly instead
of surfacing an unactionable spawn error.

The #1731 tripwire asserted the shape that does not work, so it now
asserts the opposite (never a raw spawnSync(brainSyncPath, ...)) and six
unit tests cover the resolver.

Verified on Windows: the stage now reports "OK brain-sync curated
artifacts pushed (4.2s)" and the artifacts repo committed + pushed on its
own. Affected-test set unchanged at 14 pre-existing failures before and
after, with 6 new passing tests.

* fix(gbrain): quote cmd.exe arguments at a single gbrain invocation seam

Fixes #2471. With shell:true on Windows, node/bun join argv into one cmd.exe
string without quoting, so a repo path with a space — the default
C:\Users\First Last\ layout — split into two arguments and every gbrain call
carrying a path silently targeted the wrong location (worst: `sources add
--path`). All gbrain CLI invocations now build their (cmd, argv, shell)
triple through gbrainInvocation(), which quotes risky arguments for cmd.exe's
re-parse (embedded quotes doubled). The four direct spawn sites in
lib/gbrain-sources.ts route through the seam; the #1731 static invariant is
upgraded for seamed files (any direct "gbrain" opener is the violation) and
kept as-is for lib/gbrain-local-status.ts. POSIX behavior unchanged
(shell:false, passthrough argv).

* fix(brain-sync): classify queue entries, rewrite surgically, re-push stranded commits

Fixes #2549 (P0 data loss). Every drain exit previously truncated the WHOLE
queue (six `: > "$QUEUE"` sites), which (a) destroyed privacy/mode-held
entries while misattributing them as "no allowlisted changes", (b) destroyed
entries enqueued concurrently during the drain, and (c) left push-failed
commits stranded locally with nothing ever re-pushing them until unrelated
new work arrived.

Now: compute_paths_to_stage classifies every entry (stageable / retained
privacy-held / dropped skipped-invalid-unmatched-missing); rewrite_queue
re-reads the LIVE queue at mv time and removes only this drain's processed
paths (retained + concurrent appends + unparseable lines survive; atomic
tmp+mv); an unpushed-commit detector at run start re-pushes stranded local
commits (receipted fail-closed; a receipt refusal skips the retry rather
than wedging the drain; guards missing origin/<branch>; runs inside the
existing lock). Status lines carry counts; full drop paths go to a 0600
sidecar (.brain-sync-drops.json) so filenames stay out of transcripts.
--drop-queue remains the one intentional truncation.

Matrix added: privacy retention, unmatched/missing counted drops + sidecar
mode, unparseable-line preservation, surgical same-drain retention, push-fail
commit retention + detector re-delivery on an EMPTY queue, receipt-refusal
skip. 35/35 in test/brain-sync.test.ts.

* fix(gbrain): make --full do a full code walk, not a delta one

`runCodeImport()` walked with a bare `gbrain sync --strategy code --source X`.
The strategy is right, but that walk is incremental: it only revisits files
changed since the source's checkpoint. A file missed at the ORIGINAL import is
therefore never revisited and stays out of the index indefinitely.

The reindex-code pass below cannot rescue it. It re-chunks pages that already
exist and never walks the filesystem — the same property the comment directly
above already relies on when explaining why the walk has to run first. That fix
landed one flag short: it made a fresh source get pages at all, but left
`--full` unable to discover a file the first walk skipped.

Net effect: `/sync-gbrain --full` did not perform a full walk, and re-running it
never re-detected the gap.

The failure is silent, which is what makes it expensive. Nothing errors, nothing
warns, and the verdict block still reports OK while `gbrain search` and
`gbrain code-def` answer out of a partial index. It reads as "gbrain is weak at
code questions" rather than "the index is incomplete".

Measured on two local code sources before and after this change, counting
exported functions resolvable via `gbrain code-def`: one went from 61/201 (30%)
to 180/201 (89%), importing 79 files that had no page at all; the other had
whole source files missing entirely and reached 93%. Both had been serving
search from a partial index for weeks.

Scoped to `--full` so incremental runs stay fast. `--yes` because this spawns
non-interactively and a full walk otherwise prompts to confirm import cost.

Anyone can check their own brain without applying this:

    gbrain sync --source <id> --strategy code --full --dry-run

and compare "N file(s) would be imported" against that source's page_count.
Worth knowing while doing so: the default strategy is markdown and --strategy
is per-invocation, never persisted on the source, so dropping the flag reports
strategy=markdown and a handful of files.

* fix(brain-cache): honest 'missing' instead of fabricated-empty digests on gbrain failure

A gbrain-unreachable failure in fetchRecentDecisions and fetchSalience
used to be converted into a cached 'successful' empty digest ("_No prior
skill runs recorded._" / "_No salient pages in last 14d._") that
refreshEntity stamped with last_refresh. The false negative then
survived every subsequent TTL cycle, indistinguishable from a genuine
zero-rows result. Now failure returns null, so cmdGet's existing
missing/stale-fallback machinery reports the true state — matching what
fetchGoals and fetchSimplePage already do on failure.

Also adds an Array.isArray guard in fetchRecentDecisions so a malformed
payload ({pages: {}} etc.) classifies as failure instead of crashing
refreshEntity mid-refresh; a genuinely empty pages array still renders
the honest empty digest.

* fix(test): give the schema-mismatch rebuild test a load-proof budget

The rebuild path refreshes every per-project entity against the real gbrain
CLI; with an unreachable brain each spawn runs to its own timeout, and under
machine load the stack exceeds bun's 5s default (observed 5.2-5.4s,
identically on pre-#2587 binaries — a load flake, not a regression). 30s
budget matches the sibling brain-sync suite's convention.

* fix(memory-ingest): parse the current Codex response_item rollout shape

Fixes #2105. Codex rollout JSONL moved to
{ type: 'response_item', payload: { type: 'message', role, content: [...] } };
the parser's legacy payload.message branch never fired on it, so every Codex
session imported as an empty shell (message_count: 0 — 243/243 sessions on
the reporting machine). Both shapes now parse; non-message response_items
(reasoning etc.) are ignored. parseTranscriptJsonl exported for direct unit
tests (CLI path unchanged — import.meta.main guard).

Note: #2104's staging-in-gitignored-tree half is already defended on main
(--include-gitignored + GIT_CEILING_DIRECTORIES, #2144, plus the #2486
reconcile guard) — verified, no change needed; it moves to the close-only
roster.

* fix(test): refresh codex/factory ship goldens from post-#2588 regeneration

The #2588 absorb refreshed all three ship goldens, but `bun run
gen:skill-docs` regenerates the CLAUDE host only — the codex/factory goldens
were copied from artifacts rendered before the resolver change and failed
against a fresh external-host regen in the serial test phase. Re-rendered
with --host codex / --host factory and re-copied.

* fix(make-pdf): boolean flags no longer swallow the next positional argument

Fixes #2514. The parser treated any non-flag token after a flag as its value,
so `$P generate --toc essay.md` ate essay.md as --toc's value and failed with
"missing input" — the skill's own documented usage only worked when two
boolean flags happened to be adjacent. BOOLEAN_FLAGS enumerates the no-value
flags; value flags (--watermark, --to, --title, ...) are unchanged. main()
now runs behind import.meta.main so tests import the parser directly.

* fix(repo-mode): probe GNU stat before BSD so Git Bash stops crashing

Fixes #2195. On GNU coreutils `stat -f` SUCCEEDS (filesystem status, not a
format string), so the BSD-first fallback chain never fell over — it fed
multi-word filesystem output into the cache-age arithmetic and crashed under
set -u on Windows Git Bash. GNU `stat -c` fails cleanly on BSD/macOS, making
GNU-first deterministic on both; the mtime is numeric-validated before
arithmetic as a last line of defense.

* fix(retro): point the prior-retros context query at files /retro actually writes

Fixes #2552's live half. The gbrain context-query glob targeted
~/.gstack/projects/<slug>/retros/*.md — a directory and extension nothing
writes — so prior-retro recall was dead on every brain-aware run. /retro
saves to .context/retros/*.json (repo-local); the query now reads that. The
issue's second defect (quoted-tilde orphan sweep) is already fixed on main —
the preamble sweeps with "$HOME/..." — verified, no change needed.

* fix(sync-gbrain): remove the capability-check page file left in the user's repo

Fixes #2503. On worktree-pinned brains `gbrain put` materializes the checked
page as _capability_check_<pid>.md in the current directory (the user's
repo), and `gbrain delete` removes the page but not the file — every
/sync-gbrain run left a stray file in the repo root. The check now deletes
the materialized file explicitly after the page delete.

* docs(browse): warn that hover scrolls and the daemon tab persists across sessions

Fixes #2445. Both behaviors are by design but produced confidently wrong
verification output: hovering a below-the-fold element scrolls the page
before a "rest state" screenshot (exit 0, wrong section), and the daemon's
tab survives sessions so a bare `reload` can act on whatever earlier work
left open. The screenshot-evidence section now names both traps with the
concrete guards (assert window.scrollY; always goto before verifying).

* fix(gitattributes): pin *.txt to LF

.gitattributes pins LF for every other text format in the repo (*.md,
*.tmpl, *.yml, *.yaml, *.json, *.toml, *.sh, *.ts, extensionless scripts,
even the hash-pinned diagram-render dist files). *.txt is the one text
format left unpinned.

On Windows with core.autocrlf=true, that means the two tracked .txt files
are rewritten to CRLF at checkout and then read as permanently modified:

  gstack/llms.txt                                   +174 bytes
  make-pdf/test/fixtures/combined-gate.expected.txt  +20 bytes

git status is never clean, and /gstack-upgrade's 'git stash' step saves a
phantom stash on every upgrade — one that pops back to an empty diff.

* fix(setup): install every skill runtime asset for the Claude host

On a fresh Claude install, link_claude_skill_dirs installed only SKILL.md
(+ sections/) per skill. Every skill that reads a sibling runtime file at
.claude/skills/<name>/<file> was broken out of the box: /review stopped at
'Read .claude/skills/review/checklist.md' (file never installed), and qa's
templates/references, plan-devex-review's dx-hall-of-fame.md,
gstack-upgrade's migrations/, and careful/freeze's bin/ hooks were all
silently missing. Codex/Factory/OpenCode/Kiro installers already copied
these; the primary host never did.

Fix: a shared _link_skill_runtime_assets helper installs EVERYTHING a skill
ships next to its SKILL.md, with an explicit exclusion list (F7):
node_modules, dist, test, *.tmpl, hidden files. Exclusion-list polarity
means a newly added asset installs by default instead of being silently
dropped. Assets refresh unconditionally on re-run (rm + relink/copy), so
Windows real-dir copies pick up changes after git pull.

New free test runs the real installer functions against the live repo into
a temp skills dir with a TWO-CLASS referenced-paths assertion (ENG-OV7):
alias-relative refs (.claude/skills/<name>/<path>) must exist under the
install; repo-anchored refs (~/.claude/skills/gstack/<path>) must exist in
the tree modulo an explicit built-artifact allowlist (browse/design/
make-pdf dist + the compiled gstack-global-discover). Known-broken class-2
refs (#2250 bare bin names) are ratcheted: the test fails if they quietly
start existing without the entry being removed.

* fix(setup): alias skills install as rewritten copies, never symlinks

The two back-compat alias dirs — _gstack-command (root router) and
connect-chrome (→ open-gstack-browser) — symlinked the canonical SKILL.md
verbatim, so each alias re-served the canonical frontmatter name:. Claude
Code keys skills on that name and requires global uniqueness: the
connect-chrome duplicate silently shadowed /open-gstack-browser (whichever
readdir returned first won), and the _gstack-command duplicate could drop
the ENTIRE personal-skills set — every /gstack command vanished until the
user hand-deleted the alias dirs, and the next setup re-broke it.

Fix: copy-then-rewrite. A shared _install_alias_skill_md helper reads the
SOURCE SKILL.md and writes a fresh copy with name: rewritten to the alias
dir's own name (_gstack-command / connect-chrome / gstack-connect-chrome).
sed never edits in place: on Unix the old install was a symlink into the
repo, and an in-place rewrite through it would have corrupted the generated
source (eng review E2). bin/gstack-relink gets the same treatment for its
root-alias helper, and its discovery loop now skips symlinked source dirs
so the connect-chrome repo symlink can't re-mint the duplicate.

Tests assert: installed aliases are NOT symlinks, carry their own unique
names, all installed frontmatter names are globally unique, re-runs refresh
cleanly, legacy symlinked aliases are replaced not written through, and the
source files stay byte-intact.

* fix(setup): Windows re-runs refresh installed skills for codex/factory/opencode hosts

On Windows (Git Bash / MSYS2, no Developer Mode), _link_or_copy installs
REAL directory copies. The install guards in link_codex_skill_dirs,
link_factory_skill_dirs, link_opencode_skill_dirs, and create_agents_sidecar
only ran the copy when the target was a symlink or missing — true on the
first install, never again. Every subsequent ./setup after a git pull
reported 'gstack ready (codex).' and exited 0 while silently refreshing
nothing: users ran stale SKILL.md forever. (link_claude_skill_dirs already
handled this; the other hosts never got the treatment.)

Fix: all five guard sites bypass the symlink-or-missing check when
IS_WINDOWS=1 — _link_or_copy rm -rf's the destination first, so the real-dir
copy refreshes in place. Unix behavior is unchanged (symlinks still pass the
guard via -L and serve updates without re-copying).

The new bash-fixture test drives the REAL extracted functions through the
install → upstream change → re-run cycle under IS_WINDOWS=1 (v1 must become
v2), pins the sidecar-skip behavior, checks the Unix path stayed a symlink,
and statically asserts the bypass at all five sites so factory/opencode
can't regress. Registered in the Windows-safe curated list
(KNOWN_WINDOWS_SAFE) so it actually runs on the windows-latest CI lane —
the 'bin/' pattern hit is a fixture path segment, not a shebang spawn.

* fix(uninstall): remove real-directory skill installs, gated on provenance

On Windows, setup installs skills as REAL directory copies (cp -R via
_link_or_copy). gstack-uninstall's per-skill loop filtered on [ -L ], so
every copy was skipped: --force exited 0 and printed 'gstack uninstalled.'
while leaving ~52 gstack-* directories plus _gstack-command/ behind in
~/.claude/skills. The same filter also missed the standard Unix shape (real
dir + symlinked SKILL.md), which was left as a dangling-symlink husk.

Fix: the loop now handles all three install shapes. Symlink entries keep
the existing readlink check. Real dirs with a SYMLINKED SKILL.md are removed
when the link points into gstack (same semantics as setup's cleanup
helpers). Real dirs with a REAL-FILE SKILL.md — the Windows copy shape — are
removed ONLY when both provenance gates pass (F8): (a) the directory name is
in gstack's skill inventory (source dir names, frontmatter names, gstack-
prefixed variants, and the alias dirs), and (b) the SKILL.md carries the
existing generated banner '<!-- AUTO-GENERATED from' (ENG-OV10: every
pre-v1.67 copy already carries it; a NEW marker would refuse to delete
legitimate old installs, recreating the bug). Anything failing a gate is
listed to stderr and never deleted — a user's own skill that happens to
share a name with a gstack skill survives.

Tests: a fake-tree fixture covers removed/kept/listed for every shape
(including the F8 name-collision row), and a census test asserts every
installable skill's generated SKILL.md carries the banner so the gate can't
strand a bannerless skill. Registered in the Windows-safe curated list —
the copy shape is exactly what windows-latest exercises.

* feat(setup): wire --host cursor through the full install path

'./setup --host cursor' was accepted by the flag parser and then did
nothing: no INSTALL_CURSOR branch existed, so the script built binaries,
printed no 'ready' line, and installed zero skills — Cursor users had no
way to install gstack at all.

Full install slice, re-derived from PR #2547 by @szsunyuan onto the
current installers: generate .cursor/ skill docs (host config already
existed), create a minimal ~/.cursor/skills/gstack runtime root (root
SKILL.md + bin/lib/browse assets + review checklist pair + ETHOS.md +
supabase config — bin and lib travel together because bin scripts import
../lib), link the generated gstack-* skills, and plant the repo-local
.cursor/skills/gstack sidecar WITHOUT ever wiping the generated SKILL.md
files it shares a directory with (link-before-sidecar ordering keeps the
generation fallback alive). Auto mode detects Cursor via the cursor
binary or the ~/.cursor footprint. gstack-uninstall removes
~/.cursor/skills/gstack* and per-project .cursor/skills/gstack* — and
never rmdir's .cursor itself, where Cursor stores user rules.

Re-derivation deltas from the PR: the link guards carry the #2444
IS_WINDOWS bypass (re-runs refresh real-dir copies), lib/ and
supabase/config.sh ride along like every other runtime root, and the
hosts/cursor.ts sidecar field is omitted (HostConfig no longer carries
one — sidecar behavior lives in setup).

gbrain-refresh' ran gen:skill-docs:user IN PLACE inside the install
checkout, rewriting ~16 TRACKED SKILL.md files. The checkout stayed
permanently dirty, every /gstack-upgrade 'git stash' saved a redundant
snapshot of generated content, and the growing stash list invited a 'git
stash pop' that would lay stale instruction markdown from an older gstack
over the current version — a quiet wrong-rules failure mode.

Fix, wired through machinery that already existed (gen-skill-docs
--out-dir + the symlink install layer): brain-aware SKILL.md now renders
into the untracked ~/.gstack/render/claude, and both Claude installers
serve the render when present — setup's link_claude_skill_dirs prefers
$GSTACK_HOME/render/claude/<skill>/SKILL.md, and bin/gstack-relink does
the same so a later config change can't silently flip skills back to the
blockless canonical source. setup wipes and rebuilds the render each run,
repoints installed skills after a successful render, and removes a stale
render (re-linking canonical) when gbrain is gone. gbrain-refresh renders
to the out-dir and repoints via relink; its 'this dirties the install's
git tree' caveat is retired because it no longer does.

A one-time upgrade migration (gstack-upgrade/migrations/v1.67.0.0.sh, F12)
restores the legacy dirt: unstaged modifications to SKILL.md / sections/
*.md files in the install checkout are git-checkout'd back to canonical;
anything outside that footprint (user edits, untracked files, staged work)
is left alone and reported. Idempotent, non-fatal, symlinked installs
skipped.

Tests: render-preference behavior for both installers, static pins that
every executable :user invocation carries --out-dir and the caveat text is
gone, migration fixture (restore/leave/idempotent/no-op matrix), and the
existing out-dir render test now asserts 'git status --porcelain' gains
zero new entries across a full :user render.

* fix(redact): close the remaining #1946 fail-opens — detection coverage + one-time consent

Two of #1946's reported gaps were still open after the v1.64 fail-closed
work (the git-error and oversized-diff paths in bin/gstack-redact-prepush
are already strict, chunked, and pinned by tests):

1. Detection fail-open: env.kv required an UPPERCASE name with an '='
   assignment, so 'api_key=…', 'apiKey: "…"', and 'password: …' — the
   most common real config shapes — produced NO finding at all. The pattern
   is now case-insensitive, accepts ':' (YAML/JSON) as well as '='
   assignment, and handles quoted JSON keys. It stays MEDIUM and
   entropy-gated per the calibration rule (a generic net that cries wolf
   gets bypassed), with pinned cases for each closed shape plus the
   placeholder/entropy negatives.

2. Install fail-open: nothing ever offered the guard, so a plain 'git
   push' scanned nothing and users believing themselves protected weren't.
   setup now asks ONCE for consent on a real interactive terminal
   (maintainer decision 6): an explicit answer is recorded to the existing
   redact_prepush_hook key and never re-asked; a timeout or non-interactive
   run changes nothing and keeps the hint-only posture. Default stays
   FALSE, and setup still never installs the hook itself — /ship owns the
   per-repo install (the wrong-repo invariant is pinned by the existing
   'setup carries the hint only' test).

Tests: per-shape pattern cases, prompt gating statics (key-absence + TTY +
timed default-N read), timeout-persists-nothing, non-interactive stays
hint-only with no key write, and recorded-answer-is-silent behavior runs.

Contributes to #1946 (the pre-push guard's fail-closed scan paths landed
in earlier releases; this closes the coverage and consent gaps it names).

* feat(hooks): Stop hook closes dangling timeline entries — fail-open

The preamble writes event:'started' to the project timeline at every skill
start, but the matching 'completed' write lives in prose at the END of the
skill workflow — unenforceable. An interrupted session, a context blowout,
or an agent that simply stops leaked started > completed forever, and the
leak was unrepairable after the fact (observed live in #2553).

New hosts/claude/hooks/timeline-stop-hook (+ .ts, question-log-hook shim
pattern): on Claude Code's Stop event it appends event:'completed' with
outcome 'unknown' and source 'stop-hook' for every 'started' entry in the
project timeline that has no matching completion. setup registers it via
gstack-settings-hook add-event (Stop was already an accepted event) under
its own source tag, idempotently; --no-team and gstack-uninstall remove it.

FAIL-OPEN contract (F5), pinned by tests: ALWAYS exits 0 — corrupt
timeline (bad lines skipped individually, valid ones still repaired),
missing timeline, garbage/empty stdin, bun missing from PATH (the shim
'|| true's), and an over-cap timeline (10MB skip) all repair nothing and
block nothing; errors land in ~/.gstack/hook-errors.log best-effort. The
write path is append-only with a ~2s internal budget, and a second Stop is
a no-op (already-closed entries never re-close). Correlation is
project-scoped by design — the preamble's session id is shell-local, so a
concurrent same-project session's entry may close early as a traceable
source:'stop-hook' row rather than a silent leak; the header documents the
trade-off.

* ios-qa: guard DebugBridgeTouch.m on DEBUG, not just TARGET_OS_IOS

DebugBridgeTouch.m and its header both promise the code is DEBUG-only and
never shipped:

    "Uses these private UIKit selectors (DEBUG-only; never shipped to App Store)"
    "DEBUG-only — never link in Release."

Nothing enforced it. The only guard was `#if TARGET_OS_IOS`, so a Release build
for iOS compiled the entire implementation in, private API and all.

Measured on a real app (an iOS Release build, `nm -j` on the app binary):

    DebugBridge symbols            15
    IOHIDEventCreateDigitizer       2
    AXSSetAutomationEnabled         1 symbol, 2 strings
    IOKit.framework                 4 strings

including +[DebugBridgeTouch sendTapAtPoint:inWindow:] and
_OBJC_CLASS_$_DebugBridgeTouch. That is a Guideline 2.5.1 private-API exposure
in a shippable binary, and it fails Package.swift's own stated CI invariant:

    nm -j build/Release/<binary> | grep -q DebugBridge && exit 1

WHY THE EXISTING GUARD DOES NOT COVER THIS

Package.swift documents the protection as `.when(configuration: .debug)` on the
consuming target's dependency. That works for SwiftPM consumers. It cannot be
expressed by an app that integrates DebugBridge as a local package inside an
.xcodeproj: Xcode's Filters column under Frameworks, Libraries, and Embedded
Content offers platform conditions only — iOS, macOS, visionOS — never build
configuration. So for xcodeproj consumers the documented guard silently does
nothing, which is precisely the case that was measured.

The Swift targets were already safe: all four .swift files are `#if DEBUG`
guarded and Package.swift defines DEBUG for them via swiftSettings. Only the
Objective-C target, the one that actually links private API, was unguarded.

THE FIX

1. DebugBridgeTouch.m.template now branches `#if !defined(DEBUG)` first and
   emits nothing at all in Release, falling through to the existing iOS and
   non-iOS branches only in Debug.

2. Package.swift.template declares DEBUG explicitly for the ObjC target:

       cSettings: [.define("DEBUG", .when(configuration: .debug))]

   The two Swift targets already did this. Relying on SwiftPM's implicit DEBUG
   for C-family targets is not worth betting a private-API exposure on.

VERIFIED, by compiling the generated file for iOS both ways:

    xcrun -sdk iphoneos clang -c DebugBridgeTouch.m -arch arm64 ...

    Release (no -DDEBUG)   0 DebugBridge symbols, 0 private-API symbols,   448 B
    Debug   (-DDEBUG=1)    7 DebugBridge symbols, 6 private-API symbols, 13104 B

The harness is unchanged in Debug. Release now emits an empty translation unit.

* fix(ios-qa): bridges search front-most presented content first

A presented sheet sits AFTER the screen it covers in window.subviews, so
the elements walk emitted the covered screen first — a client taking the
first match for a label activated a control the user cannot reach, and
the agent saw a success (measured on a real app: the sheet's 'Create'
button ranked 210th behind 35+ covered-screen entries). Menus, alerts and
action sheets were worse: each gets its OWN UIWindow, so keying off
isKeyWindow missed them entirely — absent from /elements, dropped from
/screenshot, untappable via /tap.

Re-derived from PR #2397 by @IDSTUK onto the current bridge templates
(the SwiftUI tap-reliability rework had moved underneath the PR):
ScreenshotBridgeImpl gains orderedWindows(in:) (visible windows front-most
first by windowLevel then insertion order, PassThroughWindow overlays
still filtered), frontmostWindow(), and searchRoots() (per window, the
top-most presented view controller's view before the window itself).
/elements walks those roots in order through the existing shared
visited-set + budget, so overlapping roots emit each view once at its
front-most position; /tap targets frontmostWindow() for both the
accessibility-activation and synthesized-touch paths; /type and /swipe
search the roots in order; /screenshot composites every window
back-to-front at the existing 1x scale. The two now-dead private
activeScene/activeKeyWindow copies in ElementsBridgeImpl and
MutationBridgeImpl are removed.

Fixture mirror synced byte-for-byte; verified with a full
'xcodebuild build -scheme FixtureApp-Package -destination
generic/platform=iOS Simulator' (BUILD SUCCEEDED, DEBUG guard from the
previous commit included).

* fix(setup-gbrain): invoke gstack-memory-ingest/gstack-gbrain-sync via bun run + .ts

/setup-gbrain's transcript-ingest steps told the agent to run
bin/gstack-memory-ingest and bin/gstack-gbrain-sync by BARE name. Neither
exists — only the .ts files ship (mode 644, no bin alias) — so the agent
dutifully reported 'script missing at install root' and the ingest/full-
sync steps dead-ended on every host (hit live under Codex; the Claude
render carries the same text).

All four template sites (probe, silent-bulk, post-answer full sync, the
preamble-hook incremental mention) and the four memory.md reference-doc
sites now use the repo's established form: 'bun run <path>/gstack-memory-
ingest.ts …' / 'bun run <path>/gstack-gbrain-sync.ts …' — matching what
sync-gbrain already does. Generated SKILL.md regenerated from the template
in the same commit.

Re-derived from PR #2409 by @SomSamantray per the wave's screening rule
(the PR edited the generated SKILL.md directly; the generated file must
come from gen:skill-docs). The contributor's structural test rides along
as-is: bare-invocation regexes with negative .ts lookahead and backslash-
continuation coverage pin every site, so the drift can't return. The
referenced-paths ratchet in test/setup-claude-skill-assets.test.ts drops
its two #2250 known-broken entries — the class-2 assertion now guards
these paths again.

Verified against #2250's site list (template lines 690/735/784-area, all
covered) plus a fresh grep: zero bare invocations remain in the template
or memory.md; the one prose mention ('gstack-memory-ingest now persists…')
is not an invocation and stays.

* fix(test): update four main-side assertions to the T3 installer contracts

Integration drift from the T3 lane: three static assertions pinned the OLD
implementation shapes that T3 legitimately replaced — the gbrain-refresh
branch no longer self-documents a reset --hard cycle (#2569 renders to an
untracked out-dir instead; the test now pins THAT), setup's regen block
renamed to the render form (re-anchored, same exit-code-propagation
invariant), and sections/ linking generalized into _link_skill_runtime_assets
(the _link_or_copy routing assertion moved into the helper). Fourth: the
uninstall neutral-target test asserted against os.tmpdir(), which reads
$TMPDIR at call time — a shard neighbor can leave it gstack-containing,
making the "neutral" symlink target match the provenance substring; the test
now falls back to a fixed neutral root and asserts neutrality explicitly.

* fix: whitelist engine-locked at all three gbrain-usable gates (#2456)

#2194 taught the classifier to report a PGLite lock held by a live
\`gbrain serve\` as engine-locked instead of broken-config, but none of the
three "is gbrain usable?" gates accepted the new status — so the symptom
moved from a wrong error to a quieter wrong suppression: gbrain-refresh
stripped GBRAIN_CONTEXT_LOAD / GBRAIN_SAVE_RESULTS blocks out of every
generated SKILL.md after every upgrade, on the RECOMMENDED /setup-gbrain
default (PGLite + local-stdio MCP spawns gbrain serve at session start).

engine-locked is the same class as timeout (#1964): the engine is
installed and healthy, a legitimate holder has the lock. All three gates
now agree:

- bin/gstack-gbrain-detect --is-ok exits 0 on engine-locked
- bin/gstack-config gbrain-refresh case arm renders instead of suppressing
- scripts/gen-skill-docs.ts --respect-detection treats it as detected

Test mirrors the existing timeout case in
test/gbrain-detection-override.test.ts (engine-locked renders brain
blocks; the sibling no-cli case still proves suppression works).

Applies the reporter's patch + test from the issue.

* fix: detect bearer-token thin clients via host MCP registration (#2520)

The #2051 thin-client fix keys detection on the remote_mcp marker in
~/.gbrain/config.json — but that marker is only written by the OAuth path
(gbrain init --mcp-only). Bearer-token installs (gbrain connect <url>
--token, gbrain's own recommended default for local/personal use) never
touch config.json, so they fell through to the local probe, failed against
the dead-or-absent local engine, and landed on missing-config / broken-db /
broken-config / engine-locked — silently suppressing brain blocks for a
fully-working remote brain.

New evidence source: hasRemoteOnlyGbrainMcp() reads ~/.claude.json MCP
registrations (user scope AND project scope) with the same classification
rules as gstack-gbrain-detect's tier-3 fallback. File-read only — no
subprocess, no network (a classifier network probe is the #1964 pathology).
Wired at two sites in freshClassify:

- missing-config branch: a bearer thin client may never have run a local
  init; if the host's only gbrain registration is remote-HTTP, that
  registration IS the brain → thin-client.
- post-probe-failure demotion: broken-db / broken-config / engine-locked
  reclassify to thin-client when the only gbrain registration is remote.
  A local-stdio sibling registration blocks the demotion (federation
  guard: a user running a local engine plus a remote team brain keeps
  precise local statuses). "timeout" is excluded — already usable, and
  may be a genuinely healthy slow local engine.

7 new unit tests in test/gbrain-local-status.test.ts: user-scope, project-
scope, engine-locked/broken-db demotion, federation guard, no-registration
discriminator, end-to-end --is-ok gate (35 pass total in the file).

* fix: resolve GBRAIN_HOME with gbrain's parent-dir semantics (#2521)

gstack treated GBRAIN_HOME as the config directory; gbrain's configDir()
treats it as the PARENT and always appends `.gbrain` itself (the contract
is explicit in gbrain's source: GBRAIN_HOME=/tmp/x → /tmp/x/.gbrain/
config.json). With GBRAIN_HOME set, gstack classified engine status from
a file gbrain never reads — the probe's two halves (file checks vs the
spawned `gbrain sources list`) looked at DIFFERENT installs, so any
resulting status was arbitrary: missing-config/broken-config against
healthy installs, or a thin-client marker gstack saw that gbrain itself
reported as "No brain configured".

New shared resolver `gbrainConfigDir()` in lib/gbrain-exec.ts is the
single source of truth. All seven gstack sites route through the contract:

- lib/gbrain-local-status.ts gbrainConfigPath (the classifier's file half)
- bin/gstack-gbrain-detect GBRAIN_CONFIG + readRemoteMcpUrl
- lib/gbrain-exec.ts buildGbrainEnv (the probe's DATABASE_URL seed —
  fixing only the classifier would have left the split-brain in the
  spawn half, flagged by the reporter)
- lib/gbrain-guards.ts gbrainHome (clones-dir + autopilot-lock paths)
- lib/gstack-memory-helpers.ts gbrainConfigPath (engine-tier fallback)
- bin/gstack-gbrain-install pre-doctor config check (shell)

Unit tests cover GBRAIN_HOME set (config found at $GBRAIN_HOME/.gbrain),
the old flat layout explicitly NOT read (both classifier and
buildGbrainEnv), and unset (~/.gbrain unchanged). Existing fixtures that
encoded the deviant flat layout are updated to gbrain's contract.

Root-cause analysis by @d-danielsun in #2521.

Deviation from the 3-site plan spec: the same deviant resolution existed
in four more sites (buildGbrainEnv, gbrain-guards, memory-helpers,
gbrain-install); fixing only three would have left gstack disagreeing
with itself as well as with gbrain, so the whole class moved to the
shared resolver in one change.

* fix: read project-scoped MCP registrations in gbrain detection (#2499)

Claude Code registers MCP servers at two scopes in ~/.claude.json: user
scope (.mcpServers) and project scope (.projects["/abs/path"].mcpServers
— what `claude mcp add` WITHOUT --scope user writes). Every gbrain
detection site read only user scope, so a correctly configured
project-scoped brain was invisible: brain-aware blocks suppressed,
remote-mode artifacts sync never recognised, and detectEndpointHash fell
through to the 'local' literal — two different project-scoped brains
hashed identically, so switching between them never invalidated the
cache, the exact scenario the function's docstring says it exists to
catch. Nothing errored; the features just quietly were not there.

Two sites fixed:

- scripts/resolvers/preamble/generate-brain-sync-block.ts: the shared
  detection block (rendered into every tier-2+ SKILL.md) now resolves the
  gbrain entry ONCE into _GBRAIN_MCP_ENTRY — user scope first, then the
  nearest-ancestor project entry for $PWD that actually carries a gbrain
  server (longest matching key with a path-boundary check: /a/repo never
  matches /a/repo2; a nested project WITHOUT gbrain doesn't shadow its
  parent's registration). _GBRAIN_MCP_TYPE and _GBRAIN_HOST extract from
  the resolved entry, so claude.json is parsed once per skill start. All
  SKILL.md files regenerated in this commit; the ship golden fixtures and
  three carve-guard skeleton caps (plan-eng-review, plan-devex-review,
  office-hours; ~1.5KB rendered growth per skill) are refreshed with
  measured values.
- bin/gstack-brain-cache detectEndpointHash: same resolution order in TS
  (user scope, else nearest-ancestor project entry by cwd, both path
  separators for Windows keys).

Tests: rendered-output tests in test/gen-skill-docs.test.ts pin the
regenerated block (static markers + a FUNCTIONAL run of the exact
rendered lines against a fixture ~/.claude.json with only a
project-scoped registration, plus an outside-cwd discriminator);
detectEndpointHash unit tests in test/brain-cache-roundtrip.test.ts cover
project-scope resolve, path-boundary, nearest-ancestor distinct hashes,
and user-scope precedence.

* fix: /sync-gbrain respects an existing valid .gbrain-source pin (#2417)

/sync-gbrain always derived a new worktree-scoped source ID, even when
the repository already carried a valid .gbrain-source pin created through
the native GBrain source workflow — silently bypassing the selected
source boundary, registering a duplicate federated source, and routing
later dream/cycle checks to the wrong source.

Now a local pin is reused when it passes the fail-closed identity checks:
the ID is syntactically valid, the source is registered, and the
registered path realpath-resolves to the current checkout (so a stale or
copied dotfile can't redirect a sync into another repo's source). A
confirmed pin is treated as user-managed — synced and attached without
add/remove, legacy migration, or federation changes. Dry-run stays
spawn-free (reads only the local marker for previews). Missing, invalid,
stale, or unreadable pins fall back to the existing generated source ID.

Absorbs PR #2417 by @exGeni (applied via git am -3; 42 tests pass in
test/gstack-gbrain-sync.test.ts including the new pin-respecting
coverage: spawn-free dry-run, symlink-equivalent registered paths,
non-dry-run sync/attach with no add/remove, dream routing, unreadable
markers, config-backed env use).

* fix: gstack-gbrain-install --dry-run no longer requires the network (#2540)

The GitHub reachability probe (curl --head, 10s max) was gated only on
--validate-only, so a --dry-run — which prints a plan and exits without
ever cloning — could fail with exit 3 "cannot reach https://github.com"
whenever the curl lost a race for sockets/DNS. Reproducible at ~15% by
running 60 dry-runs concurrently, and the cause of intermittent red in
the D5 detect-first tests, which call this exact path.

The probe now also skips under --dry-run: requiring the network for a
plan-print buys nothing and costs a real failure mode. Real installs
still fail fast when offline rather than hanging git clone.

* feat: accept 3-digit semver + package.json version sources (#2501)

Two version-source shapes failed CLOSED in a way that silently disabled
/ship's queue-collision check:

1. A --version-path / .gstack/version-path target that is a package.json
   was read as raw text: the whitespace strip turned the JSON into
   '{"name":"frontend",... which parseVersion rejected, so every read —
   local, `git show`, and rival PRs' claims through the GitHub/GitLab
   Contents APIs — fell back to 0.0.0.0 and competing claims were dropped
   as "malformed".
2. parseVersion required exactly four components, so gstack-next-version
   exited 2 on EVERY invocation in a 3-digit repo. That CLI IS the
   queue-collision check; /ship then took its documented offline path of
   naive local arithmetic, two branches cut from the same base picked the
   same version, and git merged the duplicate without a conflict.

New lib/version-source.ts holds the shared semantics so both CLIs agree
by construction: parseVersion accepts 3- or 4-digit (3 pads the micro
slot for uniform comparison), versionWidth/fmtVersion keep a 3-digit repo
3-digit through bumping and formatting, micro coerces to patch on 3-digit
repos (with a warning in the output), and extractVersion reads a .json
version-path as JSON (.version) from any byte source. gstack-version-bump
treats a package.json version-path as that repo's single source of truth
(written in place, DRIFT_* states can't arise — no second file to drift
from). Detection is by shape, not new configuration.

Scope per the wave plan's version-tooling end-state spec (decision 11,
ENG-OV1): this is the READING capability + 3-digit acceptance ONLY.
gstack's own VERSION file stays the 4-digit source of truth; nothing here
flips authority to package.json. The PR's bundled fix for the
.gstack/version-path pin being ignored by classify's base read lands
separately (#2462) — these tests drive the JSON version-path through the
explicit --version-path flag.

* fix: write/repair sync npm lockfiles' version fields (#2567)

npm records the package version twice in its lockfiles — top-level
`version` and, in lockfileVersion >= 2, `packages[""].version` (the entry
describing the root package itself) — and `npm install` keeps both in
step. gstack-version-bump write/repair updated VERSION + package.json but
left the lockfile behind, so every /ship bump in an npm repo drifted one
field per release until someone ran npm, dirtying the tree on the next
`npm install` far from the cause.

write and repair now mirror the version into package-lock.json AND
npm-shrinkwrap.json (which shares the format and, when present, is what
npm actually honors) as a pure JSON edit — no npm spawn, no
dependency-tree churn, dependency entries untouched. Per the wave plan's
version-tooling end-state spec (decision 11): synced ONLY when the file
already exists, never created (gstack itself is bun-only). A failed
manifest/lockfile write keeps the existing exit-3 half-write semantics so
classify reports DRIFT_STALE_PKG on re-run instead of hiding the drift.

Tests: 5 new cases in test/gstack-version-bump.test.ts — both lockfile
version fields synced with deps untouched, repair heals a stale lockfile,
lockfileVersion 1 (no packages map) doesn't crash, npm-shrinkwrap.json
synced without inventing a package-lock.json, malformed lockfile exits 3
loudly (26 pass total in the file).

* feat: subdirectory manifests + npm-valid version mirror (#2531)

Two gaps in gstack-version-bump's manifest handling, resolved to the wave
plan's version-tooling end-state spec (decision 11):

1. Subdirectory manifests. A repo whose only Node package lives in web/,
   app/, or frontend/ has no ROOT package.json, so join(cwd,
   "package.json") reported pkgExists:false and every bump silently wrote
   VERSION alone — leaving the manifest to be bumped by hand, which is
   exactly the drift this tool exists to prevent, in the one layout where
   it silently did nothing. All three subcommands now resolve the
   manifest as --package-json-path → .gstack/package-json-path →
   ./package.json (mirroring resolveVersionPath).

2. npm-valid mirror. VERSION is 4-digit MAJOR.MINOR.PATCH.MICRO; npm's
   semver is 3-component and rejects a fourth, so mirroring the raw form
   breaks `npm ci` in any repo npm actually manages. The manifest and its
   lockfiles now carry the npm-valid 3-digit translation (1.67.0.0 →
   1.67.0) via npmVersion() in lib/version-source.ts. VERSION stays the
   4-digit source of truth. classify judges drift against the TRANSLATED
   form — a correctly-synced `0.1.25` no longer reads as eternal drift
   against `0.1.25.0` — and grandfathers the pre-v1.67 1:1 four-digit
   mirror as in-sync (flagging it DRIFT_UNEXPECTED would hard-stop /ship
   on every existing repo on upgrade day; the next write migrates the
   manifest to the translated form). Lockfiles are synced beside the
   resolved manifest — including beside a pinned JSON version-path — and
   only when they already exist.

classify output gains pkgPath and expectedPkgVersion for observability;
write/repair report packageJsonPath + packageJsonVersion. The /ship Step
12 prose (ship/SKILL.md.tmpl) documents the resolution chain and the
translation; SKILL.md files regenerated and ship golden fixtures
refreshed in this commit.

Tests: subdirectory pin + --package-json-path override, translated-form
classify (FRESH/ALREADY_BUMPED, no false drift), grandfathered 1:1
mirror, genuine divergence still drifts, repair to the npm-valid form
(33 pass in test/gstack-version-bump.test.ts; 526 pass across the five
affected files including goldens and parity).

Re-derived from PR #2531 by @CarringtonCreative on top of the 3-digit/
JSON version-source work, under decision 11 (which resolves the PR's
lockfile-gated translation in favor of an unconditional npm-valid
mirror).

* feat: git-based version allocator when the PR queue is unreachable (#2545)

When the host query (gh/glab) failed, gstack-next-version returned
offline:true with an EMPTY claim set, and /ship's documented fallback was
local BUMP_LEVEL arithmetic. Local arithmetic cannot see a sibling's
claim, so the fallback allocated a version another open PR already held —
observed in a downstream repo where two merged PRs both read v0.1.57.0
(and an audit found four such duplicate pairs over three weeks).

New fetchGitClaimed() degrades the QUEUE VIEW without degrading the
ALLOCATION: git already knows what the API was asked for. It reads every
remote-tracking branch's pinned version file (through extractVersion, so
JSON version-paths resolve on remote refs too and each branch's own digit
width is preserved) plus the versions already shipped in the base's last
400 commit subjects (3- or 4-digit; the cap announces itself in warnings
when it truncates). The fallback runs only when the host told us nothing
— the online path is untouched — and the output gains a load-bearing
`fallback: "git" | null` field that /ship can branch on, plus explicit
warnings for both the recovered-from-git and the nothing-found cases.

Tests: end-to-end stub-gh offline contract (fallback:'git' + a valid
version + the warning), sibling-claim discovery from remote-tracking
refs, the pick advancing past the sibling's claim, shipped-subject
scanning, JSON version-path claims on remote refs, and non-repo
degradation to a warning (45 pass in test/gstack-next-version.test.ts).

Re-derived from PR #2545 by @CarringtonCreative under the wave plan's
version-tooling end-state spec; the PR's own VERSION/CHANGELOG stamping
is stripped (release stamping happens at /ship time, not per commit).

* fix: version-bump honors the .gstack/version-path pin in versionRel (#2462)

cmdClassify's current-version read already resolved the
.gstack/version-path pin, but versionRel — the repo-relative path fed to
`git show origin/<base>:<path>` — was derived from the CLI flag alone
(`argVal(args, "--version-path") ?? "VERSION"`). In a pinned repo with no
explicit flag, base and current therefore read DIFFERENT files: current
from the pinned file, base from the root VERSION. On a repo with no root
VERSION, the base always read 0.0.0.0 — and the pinned-JSON handling
never engaged, so a pinned package.json was read as raw text
(currentVersion 0.0.0.0) and `write` would have overwritten the manifest
with a bare version string.

New resolveVersionRel() resolves the pin's REPO-RELATIVE form once
(flag → .gstack/version-path first line → "VERSION"); classify, write,
and repair all derive both the relative and absolute paths from it, so
base and current reads can no longer diverge. The old resolveVersionPath
(which returned an absolute path `git show` cannot use) is folded in.

Unit tests (the ENG-OV6 spec case plus write/repair coverage): pin set +
no flag → classify reads base AND current from the SAME pinned file
(plain-text sub/VERSION and pinned frontend/package.json, both against a
real git base with NO root VERSION anywhere), write updates the pinned
manifest in place without inventing a root VERSION, repair treats the
pinned JSON as single-source, and the explicit flag still overrides the
pin (38 pass in test/gstack-version-bump.test.ts).

Re-spec'd per ENG-OV6 from the report in #2462 (the originally-filed
classify-read hypothesis was already handled; the live bug was the :138
versionRel derivation). Same fix shape independently identified in
PR #2501 by @YiftahR.

* fix: diff-scope glob coverage, honest exit contract, dirty-tree visibility (#2526, #2455, #2299)

Three silent-skip classes in bin/gstack-diff-scope, each of which quietly
disabled scope-gated reviewers in /ship and /review:

1. Pattern gaps (#2526, #2455). `*/api/*` required a path segment BEFORE
   api/, so a root-level api/ layout (Vercel serverless, Next.js pages/api
   at root) never set SCOPE_API — 63 serverless functions in the
   reporter's payments repo, none ever classified, the API-contract
   specialist silently skipped on every payment PR (it found a CRITICAL
   when run by hand). Same for root-level migrations/. And the Rails
   data_migrate gem's db/data/ data migrations — arbitrary Ruby run
   unattended against production data — fell through to plain BACKEND, so
   the [NEVER_GATE] data-migration specialist never got the chance to
   run. Added: api/*, migrations/*, db/data/*, data_migrations/*.

2. All-false was indistinguishable from "could not look" (#2526). New
   contract: empty change set → all false exit 0; >=1 match → flags
   exit 0; changed files with ZERO matches → SCOPE_ERROR=unmatched + the
   unmatched paths as comment lines + exit 2 (a new top-level layout now
   trips loudly instead of invisibly disabling reviewers); unresolvable
   base ref (shallow CI checkout) → SCOPE_ERROR=no_base + exit 2 instead
   of a green that means "we could not look". Every output line stays a
   shell-safe assignment or comment for sourcing consumers, which
   tolerate the nonzero exit today (source ... || true / eval).

3. Uncommitted work was invisible (#2299). /ship detects scope in Step 9,
   BEFORE it commits in Step 15, so the common start-work-then-ship flow
   ran the classifier against an empty diff and skipped every reviewer.
   The change set is now the UNION of committed diff + working tree +
   untracked files. Also from #2299: the single first-match-wins case
   made the nine flags mutually exclusive (Button.test.jsx set FRONTEND
   but not TESTS; util.test.ts the opposite) — each category now gets its
   own case, with BACKEND deliberately still excluding frontend
   component/view files. And file listing is NUL-safe (git diff -z), so
   non-ASCII paths no longer defeat extension globs via octal quoting.

Deliberate behavior change (flagged in #2299): with independent flags, a
backend test file sets BACKEND and TESTS, which can trip the security
specialist's SCOPE_BACKEND gate on test-only PRs — errs toward more
review, not less.

Table-driven tests cover every glob class (root api/, nested api/,
controllers, openapi, root/nested/prisma/db-migrate/db-data migrations,
dual-category test files, auth, prompts, docs, plain classes), the
four-state exit contract, dirty-tree + untracked visibility, and the
non-ASCII path case (39 pass in test/diff-scope.test.ts).

Fixes shaped by the reporters' patches: @grant-ship-it (#2526),
@mkyed (#2455), @ShahriarLak (#2299).

* fix(redact-prepush): don't re-scan commits a catch-up merge brought in

`remoteSha..localSha` is "everything new on this branch", which is not the
same as "everything new to the remote". Merge origin/main into a feature
branch and every commit main gained since that branch's last push becomes
an added line — content that is already published, already scanned, and
not this push's doing.

Two consequences, both observed:

  · FALSE HIGH FINDINGS. A placeholder connection string in a fixture
    someone else had already merged blocked an unrelated push as
    db.url_with_password, telling the operator to rotate a credential
    over a file they never touched. A guard that cries wolf on catch-up
    merges is one people learn to bypass reflexively — which is exactly
    how a real secret gets through.
  · OVERSIZED SCANS. The SCAN_CHUNK_BYTES comment already records a
    1,146,782-byte diff from "a feature branch catching up to a busy
    main" blowing the engine's 1 MiB cap. Same root cause, treated there
    as a size problem. Narrowing the range fixes the size too.

A two-dot range cannot express this: after merging main, neither the
remote tip nor the merge-base with main is an ancestor of the other, so
no single base excludes both.

The narrowed range is `rev-list localSha --not remoteSha --remotes`.
remoteSha STAYS the base — it is what git tells us the remote has, and is
authoritative in a way --remotes is not, since tracking refs can be
absent or stale. Using --remotes alone excludes nothing in a repo without
them, so every commit ever made reads as new. That is the same false
positive from the other direction, and it is what the existing test
"only NEW content is scanned (remote..local), not pre-existing" catches.

When excluding tracking refs changes nothing, this push has no catch-up
commits and the plain range already describes it exactly — so we defer to
it. That keeps every non-catch-up push on the original gitStrict diff
path, which is what #1946's fail-closed regression test exercises. A
narrowing that silently retired that test would be a worse trade than the
false positives it set out to fix.

Each commit is diffed alone. A merge's combined diff shows only content
present in no parent, so a secret introduced while resolving a conflict
is still caught while an ordinary merge contributes nothing.

Tests: 22/22 existing prepush tests still pass (two of them fail without
the remoteSha base and the defer-to-plain-range guard respectively —
verified by mutation). 5 new tests build real repositories on disk and
pin both directions: a catch-up merge no longer re-scans published
content, and secrets in new commits, in merge resolutions, and in
repos with no remote are all still scanned.

Absorbs PR #2592 by @Two-Six-Alpha-1115 (applied via git am -3; 5 new
tests pass in test/redact-prepush-scan-range.test.ts). Also narrows the
range for the rebased-force-push shape reported in #2573 — proven by the
follow-up regression test.

* fix(redact): parcel IDs are not phone numbers

A county tax-map parcel ID (APN) reads as a national-format phone number
to `pii.phone.e164` — the same collision class as the digit-only UUID
that `insideUuid` already guards. `12-3456789.000` matches, and so does
its normalized `123456789000`.

This is not a rare edge. Land, title and property-tax repos carry APNs
by the hundred; a single title branch pushed 2 MEDIUM findings, and the
same shape recurs in every fixture, mart and smoke in the domain. A
guardrail that cries wolf on the domain's primary identifier is one
people learn to wave through, which is how a real HIGH finding
eventually gets ignored.

The guard is deliberately narrow, in two tiers:

1. The DOTTED form is exempt on its own shape. No phone convention puts
   a dot before a trailing 3-4 digit group after a 4-8 digit middle.
   Hyphen-only variants (22-0001-000) are NOT shape-exempted — those
   genuinely are phone-shaped.

2. A DIGITS-ONLY span is phone-shaped in isolation, so it earns the
   exemption only by evidence: it must be the exact digit-normalization
   of a punctuated APN within the surrounding window. Fixtures and marts
   carry the pair; a real phone number has no such twin. This reads the
   document's own evidence instead of guessing from digits.

Verified against the unmodified engine over inputs spanning every rule
family (AWS, PEM, GitHub PAT, email, IP, credit card, SSN, timestamp,
UUID, nine phone formats): exactly one behavior changed, the APN pair.

The new test pins both directions and was proven red under mutation —
stubbing the guard to `return true` (the dangerous blanket-exemption
failure) fails 12 of 15; `return false` fails 3.

Absorbs PR #2591 by @Two-Six-Alpha-1115 (applied via git am -3; 96 tests
pass across test/redact-parcel-id-false-positive.test.ts +
test/redact-engine.test.ts, and the pattern-lint / CLI / prepush-hook /
autoredact suites stay green).

* test: prove the rebased force-push shape is scanned correctly (#2573)

#2573: after `git rebase origin/main`, the feature branch's remote tip
still exists locally (the pre-rebase tip) but is no longer an ancestor of
HEAD, so the old `remoteSha..localSha` range swept in every upstream
commit rebased onto — 1.14 MiB scanned instead of 0.27 MiB on the
reported repo, tripping the engine's 1 MiB cap and blocking the push
with engine.input_too_large (a HIGH that meant "the engine never ran",
not a finding).

The catch-up-merge narrowing (`rev-list localSha --not remoteSha
--remotes`) covers this shape too: the upstream commits are reachable
from origin/main's remote-tracking ref, which exists by construction —
you cannot have rebased onto origin/main without it. No residual gap
found; this lands the proof alone, end-to-end through the actual hook
binary with the real pre-push stdin protocol:

- fixture sanity: the pre-rebase tip exists locally, is NOT an ancestor,
  and the OLD two-dot range would have swept in the upstream credential
- a clean rebased force-push passes — someone else's already-published
  HIGH-shaped fixture no longer blocks it
- coverage is not narrowed: a HIGH in a rebased commit of our own still
  blocks
- the scanned commit set is exactly the rebased own commits, so scan
  size is proportional to OUR work, not to how busy main was

Analyzed non-gap, recorded in the test header: upstream commits in NO
remote-tracking ref cannot arise from the standard flow — rebasing onto
origin/<branch> requires the tracking ref, and rebasing onto a purely
local branch means the "upstream" content was never published, so
scanning it is correct.

* deps(browse): bump playwright + playwright-core to 1.62.1 (P0 #2554 vehicle)

Split from dependabot #2582 per plan OV3: this commit bumps ONLY
playwright (^1.58.2 -> ^1.62.1, lock resolves playwright@1.62.1 +
playwright-core@1.62.1 exactly). puppeteer-core, @huggingface/transformers,
marked, and socks are deliberately NOT bumped here — they land separately
(73b) gated on the ONNX sidecar smoke.

Why: bun.lock pinned playwright(-core)@1.58.2, whose Chromium build
macOS XProtect now kills on launch — browse is dead on macOS (#2554).
1.62.1 ships Chromium 151.0.7922.34 (headless shell v1234), which
launches clean.

Verification: bunx playwright install chromium (Chrome Headless Shell
151.0.7922.34 downloaded), then the full browse suite from browse/:
2016 pass / 32 skip / 2 fail across 129 files (133.9s). Both fails are
playwright-independent: data-platform.test.ts "rejects paths in cwd"
expects <cwd>/package.json to exist (browse/ has none; passes from repo
root, the shard runner's cwd — 15/15), and stealth-webdriver.test.ts
passes standalone (15/15) — a 5s-timeout flake under full-suite parallel
load.

* fix(browse): XProtect launch-kill self-heal — classify, quarantine-clear, bounded reinstall (P0 #2554)

macOS XProtect definition updates can start SIGKILLing the exact Chromium
revision the lockfile pins (xprotectd killed revision 1208's headless shell
at spawn; the failure surfaced as a generic launch timeout). New
browse/src/xprotect-heal.ts heals it, once per process:

- Classifier (F9): positive signatures sourced from the #2554 report +
  Playwright's launch-error format (signal=SIGKILL process-exit lines, and
  launch timeout WITH a <launched> marker), negative-checked FIRST against
  missing executable, spawn EACCES/EPERM, Linux sandbox denials, and plain
  exitCode=1 crashes. darwin-gated.
- Heal (F4 one-shot, in-memory flag): clears com.apple.quarantine via
  `xattr -dr` on chromium* revision dirs in the Playwright cache ONLY —
  never a GSTACK_CHROMIUM_PATH bundle (probePoisonedChromiumBundle's scope
  contract, double-gated at the call sites via usesCustomExecutable).
- Reinstall (E1/ENG-OV3): `bunx playwright install --force chromium` run
  FROM THE GSTACK INSTALL ROOT — the root whose
  node_modules/playwright-core/browsers.json pins the SAME chromium
  revision our embedded playwright-core expects (a cwd-resolved bunx would
  fetch latest and heal to the wrong revision). Bounded at 120s with a
  process-GROUP SIGKILL on timeout; on any heal failure the caller gets the
  ORIGINAL launch error + manual `bunx playwright install chromium`
  guidance — the CLI never hangs.
- Verification (F9): post-install asserts the REGISTRY-derived executable
  path exists (the revision dir playwright-core 1.62.1 expects), not merely
  install exit 0.
- Logging (F11): every action emits one structured stderr line
  ([browse:xprotect-heal] JSON).

All three launch sites in browser-manager.ts (headless launch, headed
launchPersistentContext, handoff relaunch) route through
launchWithXProtectHeal with one post-heal retry. setup's
ensure_playwright_browser failure path gains the same quarantine-clear
(_clear_playwright_quarantine, Darwin-only, Playwright cache scope) before
its Chromium reinstall.

Tests: browse/test/xprotect-heal.test.ts — 33 pass (classifier both
polarities, one-shot guard incl. failed-heal consumption, custom-executable
scope, registry-revision expectation vs playwright-core browsers.json,
install-root revision matching, quarantine-clear scope, wrapper retry +
guidance surfacing). browser-manager unit/custom-chromium: 36 pass.
bridge-chromium-e2e real-launch smoke: 3 pass. setup-windows-fallback
ln-invariant: 9 pass. bash -n setup: clean.

Fixes #2554.

* fix(browse): daemon owns signal policy — handleSIG*:false at launch sites + SIGHUP shutdown (#2220)

Playwright's default handleSIGINT/handleSIGTERM/handleSIGHUP handlers close
Chromium the moment the DAEMON process receives a signal — which fights the
deliberate headless SIGTERM-ignore in server.ts (Claude Code's Bash sandbox
fires SIGTERM when the parent shell exits between tool invocations; the
daemon survives it by design, but Playwright's handler killed its browser
out from under it). All three flags are now false at all three launch sites
(headless launch, headed launchPersistentContext, handoff relaunch).

ENG-OV4: the daemon had NO process-level SIGHUP handler (only SIGINT and
the mode-aware SIGTERM handler), so flipping handleSIGHUP:false alone would
remove the ONLY Chromium cleanup on hangup. server.ts now routes SIGHUP to
activeShutdown — the same shutdown path SIGINT uses (closes Chromium,
releases ports, removes the state file).

Static tripwire (browse/test/launch-signal-flags.test.ts, house
grep-style): every chromium.launch/launchPersistentContext site must carry
the three flags (site count pinned at 3 so a NEW launch site trips it),
server.ts must keep the SIGHUP→activeShutdown route, and the deliberate
headless SIGTERM-ignore must still exist (the reason handleSIGTERM:false is
safe — pinned in the test's header comment).

Tests: launch-signal-flags 3 pass; browser-manager-unit 28 pass;
bridge-chromium-e2e real-launch smoke 3 pass.

Fixes #2220.

* fix(browse): absorb #2414 residuals — EPERM-alive liveness + Windows-dead test tripwires (re-derived)

Re-derive of PR #2414 (SYKhayyat) onto current main. Most of the PR already
landed in earlier waves: the tick-derived RESPAWN_GUARD_WINDOW_MS, the
spawnTerminalAgent windowsHide flag, the process-liveness regression tests,
and the browse/test import.meta.path sweep are all on main. Two pieces
remained:

1. isProcessAlive EPERM semantics (error-handling.ts): on the signal-0 path,
   EPERM means the process EXISTS but we lack rights to signal it — that is
   ALIVE. Returning false made callers that validate liveness before killing
   (killAgentByRecord, the terminal-agent watchdog) skip the kill and respawn
   around a survivor — the self-reinforcing one-leak-per-tick chain from
   #2414/#2295. Matters for cross-user PID checks.

2. Six test/ files ADDED SINCE the PR reintroduced the exact Windows bug its
   second commit fixed: `new URL(import.meta.url).pathname` yields
   `/C:/Users/...` on Windows, so path.resolve prepends the cwd drive and
   every tripwire ENOENTs instead of asserting anything (egress-receipt,
   egress-lib, egress-receipt-wiring, gstack-egress-cli,
   pty-skill-seeding-wiring, skill-census). All six now use
   import.meta.path — Bun's absolute native path, identical arity.

The remaining #2414 piece — replacing the Windows tasklist probe with
signal-0 — lands as its own commit (#1952) on top of this shape.

Tests: the 6 touched test files 47 pass; process-liveness-windows +
error-handling 13 pass.

* fix(browse): isProcessAlive uses signal-0 on every platform — no more tasklist probe (#1952)

Replace the Windows tasklist shell-out in isProcessAlive with
process.kill(pid, 0), unifying all platforms on the POSIX idiom. Node maps
signal-0 to an OpenProcess existence check on Windows — and the Windows
daemon runs under Node (dist/server-node.mjs + bun-polyfill, the documented
oven-sh/bun#4253 fallback) — so the probe is portable.

Why the shell-out had to go, beyond the cosmetic conhost flash the watchdog
blinked into the foreground every 60s (#1952): a Bun.spawnSync that hits
its timeout still RETURNS with partial stdout, so the `.includes()` PID
match answered "dead" for LIVE processes under load — the false-negative
half of the #2414/#2295 leak chain. Signal 0 spawns nothing, cannot time
out, and is ~5 orders of magnitude faster (measurements in #2414). EPERM
still reports alive (process exists, we just can't signal it).

Layered on the post-#2414-absorb shape: test 3 in
process-liveness-windows.test.ts now asserts the probe is subprocess-free
on ANY platform (win32 exemption dropped), test 4's static tripwire loses
its error-handling.ts exemption (a `tasklist … PID eq` existence probe
anywhere in src/ now fails CI), and windows-spawn-hide.test.ts drops its
tasklist-in-error-handling needle (nothing spawns, which is stronger than
hiding the window).

Tests: process-liveness-windows + windows-spawn-hide + error-handling —
17 pass, 0 fail.

Fixes #1952.

* fix(browse): windowsHide sweep — flag every residual child_process site + full-census tripwire (#2160, #2415)

Add windowsHide:true at every remaining direct child_process call in
browse/src that could flash a console window on Windows:

- project-slug.ts (execSync gstack-slug)
- browser-skills.ts (cp.spawnSync git rev-parse)
- security-sidecar-client.ts (spawn — the LONG-LIVED Node sidecar, whose
  missing flag parked a console window on the taskbar for the daemon's
  whole lifetime)
- find-security-sidecar.ts (execFileSync node --version)
- meta-commands.ts (execSync git rev-parse in inbox + the osascript
  activate call)
- browse-client.ts (cp.spawnSync git rev-parse)
- file-permissions.ts (execFileSync whoami.exe — Windows-only, ran bare)
- cli.ts (nodeSpawn osascript)

windows-spawn-hide.test.ts gains a SWEEP test on top of the existing
needles: it censuses EVERY child_process binding in src/ (static imports
incl. aliases, `await import()` / require destructures, and `import * as
cp` namespaces — 15 call sites across 10 files today) and fails CI on any
call without windowsHide within its options window. Exemptions carry
reasons — the one today is domain-skill-commands' interactive $EDITOR
spawn (stdio:'inherit'; CREATE_NO_WINDOW would detach a console editor
into an invisible console).

Tests: windows-spawn-hide 5 pass; file-permissions 19 pass; browse-client
28 pass; browser-skill-commands 29 pass (81/81 combined).

Fixes the app-side half of #2160; closes out #2415's residuals.

* fix(browse): fail-fast busy-daemon semantics — never auto-kill an alive pid, add --force-restart (#2219)

The CLI killed live-but-busy daemons: a heavy dev-mode page (cold-compiling
Next.js route, timed-out navigation still churning) kept the daemon from
answering /health longer than the old ~1s probe window (3 × 250ms), so the
connection-error path declared it dead, SIGTERMed a healthy process, and
every kill lost the session's tabs, cookies, and logins (reproduced 4/4 in
the #2219 report).

New contract (decision 9 / F10):

- probeHealthWithBackoff is budget-based: ~8s total
  (HEALTH_PROBE_TOTAL_BUDGET_MS), 500ms intervals, each probe self-bounded
  at 2s — sized to the observed busy windows.
- decideDaemonRestart (pure, exported, unit-tested) encodes the IRON RULE:
  healthy-after-probe → retry the SAME daemon; alive+unhealthy →
  "daemon busy — retry or --force-restart" + NONZERO exit, daemon untouched;
  only a DEAD pid (or an explicit --force-restart) reaches kill+restart.
- --force-restart global flag (extractGlobalFlags): the one consent path
  that replaces a live daemon, always announcing the state it costs.
- Wired at all three kill sites: sendCommand's connection-error branch,
  ensureServer's stale-state path (which previously killServer'd any alive
  pid whose single 2s health probe missed), and connect — which used to
  "Kill ANY existing server" and now refuses to replace a healthy daemon
  without 'browse disconnect' or --force-restart. pair-agent's internal
  headed switch passes --force-restart explicitly (the mode switch is that
  command's stated purpose), preserving its behavior.

E5 IRON RULE regression tests (busy-daemon-iron-rule.test.ts, real spawned
CLI + fake daemons + live sleep-pid stand-ins per the
busy-daemon-recovery.test.ts pattern): healthy daemon SURVIVES connect
(refused with guidance, pid alive, state file untouched); wedged-alive
daemon + plain command → busy report, nonzero exit, pid alive; wedged
daemon + --force-restart IS killed and a real replacement daemon serves the

lifecycle); busy-daemon-recovery + proxy-config + daemon-mismatch-refuse +

* fix(browse): `stop` on a dead daemon is success — never boots a daemon to stop it (#2254)

Two changes, one contract:

- Pre-server short-circuit: `browse stop` is handled BEFORE ensureServer().
  No daemon state → "nothing to stop", exit 0. Stale state (dead pid AND
  dead port) → clean the state file, exit 0. The old flow routed stop
  through ensureServer(), which started a fresh daemon + Chromium
  (multi-second boot, resource churn) purely so it could be told to shut
  down — or crashed on the stale state.
- Reconnect branch: a connection error while sending `stop` where the pid
  turns out dead (daemon died mid-flight, between the short-circuit check
  and the send) is treated as SUCCESS — the desired end state (no daemon)
  already holds — instead of the crash-restart path.

Integration tests (stop-dead-daemon.test.ts, real spawned CLI + scratch
BROWSE_STATE_FILE): stop with no state exits 0 and spawns nothing (a
spawned daemon would have written the state file); stop with a stale state
file (dead pid + verified-closed port) exits 0, cleans the state, and
spawns nothing.

Tests: stop-dead-daemon 2 pass; busy-daemon-iron-rule 8 pass;
busy-daemon-recovery 1 pass (11/11 combined).

Fixes #2254.

* fix(upgrade): /gstack-upgrade stops a stale daemon — deferring to a busy one (#2551)

A browse daemon started before an upgrade keeps serving the OLD binary's
code after `git reset --hard` + `./setup` — the running process holds the
old executable, so users on the "new" version kept getting pre-upgrade
behavior (and config-mismatch refusals against the new CLI) until they
happened to stop it by hand.

New unconditional Step 4.8 in gstack-upgrade/SKILL.md.tmpl (+ regen, same
commit): compare the running daemon's recorded binaryVersion (the
readVersionHash git-SHA the server stamps into its state file) against the
freshly built browse/dist/.version.

- Stale + responsive → `browse stop` (graceful), telling the user
  old→new hash; the next command boots a daemon on the new binary.
- Stale + BUSY → DEFER (decision 10): never kill a busy daemon during
  upgrade. Print the old→new hash and the escape hatch —
  `browse stop` when it finishes, or `browse --force-restart stop` now.
- Dead pid / matching hash / no state → silent no-op.

Tests: skill-validation + gen-skill-docs 731 pass after regen.

Fixes #2551.

* fix(browse): terminal-agent allocates from the fixed port scan range, not port:0 (#2314)

The terminal-agent bound `Bun.serve({ port: 0 })` and kept that OS-assigned
port for its whole (weeks-long) lifetime. `port: 0` draws from the OS
EPHEMERAL range (49152-65535 on macOS) — the exact pool every short-lived
`app.listen(0)` test server draws from — so the agent squatted ports that
test suites expected to receive and silently absorbed their traffic as
phantom 404s (two squatting daemons verified in the report).

Fix per decision 8: extract the main server's port allocation into
browse/src/port-allocator.ts (checkPortAvailable / isPortAvailable /
findAvailablePort + the 10000-60000 range constants and the actionable
sandbox-vs-occupied error formatters, all verbatim from server.ts) and make
BOTH long-lived listeners use it — server.ts's findPort is now a thin
findAvailablePort(BROWSE_PORT) wrapper, and terminal-agent's buildServer
takes a pre-allocated port from the same range. No terminal-port consumer
carries a range assumption (they read the port file), verified by grep.

Tests: terminal-agent-port-range (new — allocator stays inside
10000-60000 and below the 49152 ephemeral floor, explicit-port honored,
occupied-explicit throws, static tripwires pin no-port:0 in
terminal-agent.ts and the shared wrapper in server.ts) + findport +
terminal-agent-integration/session-routing/detach-reattach +
dual-listener: 67 pass, 0 fail.

* fix(browse): capture daemon stdout/stderr to browse-daemon.log + Windows polyfill spawn fixes (re-derived from #2461)

The detached daemon's stdout/stderr were wired to 'ignore' on every
platform, so every console.error('[browse] FATAL: ...') from a Chromium
crash, uncaughtException, or unhandledRejection was discarded at the OS
level — a crash-and-respawn looked identical to every other dropped
session, with nothing on disk recording why. Both spawn paths now redirect
to <stateDir>/browse-daemon.log (append mode, accumulates across respawns):
the Unix path via an fd from openDaemonLogSink(), the Windows path by
opening the fd INSIDE the node -e launcher string (an fd opened in cli.ts
would not cross the spawn boundary). Unwritable state dir falls back to
'ignore' rather than failing the launch.

Capturing daemon output is what surfaced the PR's second fix, still valid
on current main: bun-polyfill.cjs's Bun.spawn/spawnSync called Node's
child_process with a bare command name, which Windows can't resolve without
PATHEXT lookup ("spawn bun ENOENT" from the terminal-agent respawn path).
Routed through cross-spawn on win32 (now a direct dependency; already in
the tree transitively via @modelcontextprotocol/sdk) — the PR verified
empirically that shell:true does NOT neutralize cmd.exe metacharacters
reachable via `$B skill run` arg passthrough, and that Node refuses .cmd
spawns without a shell (CVE-2024-27980), so cross-spawn's combined PATHEXT
resolution + argument escaping is the only correct shape. The PR's third
fix (resolveDisconnectCause throwing "browser?.process is not a function")
already landed on main via the #2085 typeof guard — not re-applied.

F6 log hygiene (daemon-log-hygiene.test.ts): needle tests pin the log
wiring on both spawn paths (and that stdio 'ignore','ignore','ignore'
never returns), that bun-polyfill stays on cross-spawn with no shell:true,
that NO console.* call in src/ passes a token value (interpolated or bare
arg), and that the page-content carrier modules (tab-session, buffers,
content-security, activity) stay console-free — so neither AUTH_TOKEN nor
unsanitized page-derived strings can reach browse-daemon.log.

Tests: daemon-log-hygiene + bun-polyfill + windows-spawn-hide +
cli-setsid-daemonize 21 pass; stop-dead-daemon + busy-daemon-iron-rule
(exercises a REAL daemon boot through the new log-fd wiring) 10 pass.

* fix: raise gbrain version-probe timeout to 10s on Windows

On Windows the gbrain CLI is a .cmd shim that runs `bun run cli.ts`.
A cold spawn takes over the 2s timeout in resolveGbrainBin (warm runs
are ~700ms), so the probe times out, localEngineStatus classifies the
engine as "no-cli", and the 60s status cache then serves that false
negative to every skill preamble and sync run. /sync-gbrain skips the
memory stage with "gbrain CLI not on PATH" even though the CLI works.

Give the shim 10s of headroom, gated on NEEDS_SHELL_ON_WINDOWS so
POSIX keeps the cheap 2s probe. Applies to both resolveGbrainBin and
readGbrainVersion.

Observed on Windows 11, bun 1.3.14, gbrain 0.42.59.0.

* fix(browse): remove the dead security shield + unfed /health.security (re-derived from #2557)

The sidebar's SEC shield has been dead UI since the PTY terminal rewrite:
nothing set its data-status, nothing unhid it, and the /health.security
field behind it read getStatus() off ~/.gstack/security/session-state.json
— a file whose ONLY writer (sidebar-agent.ts) was deleted with the chat
path. /health therefore reported a permanent 'inactive', or a stale
FALSE-GREEN 'protected' wherever an old state file survived on disk (a
single unit-test run was enough to plant one). A green shield sourced from
leftover state reads as "no threats detected" when the real state is "not
measured" — the same fail-open class as #2026.

Removed (dead surfaces only): the shield markup/CSS and the stale
sidepanel.js comment; the /health security field and server.ts's getStatus
import; getStatus / SecurityStatus / StatusDetail / SessionState /
read+writeSessionState (and security.ts's dead child_process import); the
session-state + getStatus unit tests — including the round-trip test that
wrote real fixture data into ~/.gstack and left /health green forever.
(The PR's security-sidepanel-dom.test.ts deletion already happened on main
via #2230; its resolveDisconnectCause guard landed via the #2085 typeof
fix. Neither re-applied.)

Kept, per ENG-OV9 — security.ts has LIVE consumers: the pure combiner
(combineVerdict + THRESHOLDS), canary utilities, and extractDomain stay;
server.ts's /pty-inject-scan L4 path (isSidecarAvailable + scanWithSidecar)
is untouched. browse/test/server-security-surface.test.ts pins BOTH
directions: the dead surface stays dead (no /health security field, no
getStatus import, no reader of the security session-state file, shield
markup gone) and the live half stays live (sidecar wiring in server.ts,
combiner/canary exports in security.ts, /health carries no token — the
v1.63 regression wall). A future re-feed from LIVE signals must update
that test deliberately rather than resurrect the state-file path.

F13 (same commit): CLAUDE.md's Sidebar security stack section, ARCHITECTURE.md's
prompt-injection Visibility + critical-constraint paragraphs, and
BROWSER.md's security section now describe the removed surfaces as history,
not live features.

Net -166 lines. Tests: server-security-surface + security +
security-adversarial(+fixes) + security-integration + server-auth 114 pass;
sidepanel-* + extension-token + extension-sender-auth 58 pass / 2 skip.

* fix(browse): capture browser-skill subprocess output via temp files, not pipes (core of #2559)

Under a loaded parent, the FIRST piped Bun.spawn in a process
intermittently yields an empty stderr even though the child wrote it and
exited 0 — measured identically with readers-attached-before-exit and with
a manual getReader() drain, so it's loss inside the async pipe plumbing,
not read ordering. It flaked `$B skill test` (bun test writes its banner to
stdout and the pass/fail summary to stderr, so a dropped stderr silently
degraded the result to just the banner) and would blank a skill's JSON
result on `$B skill run` while still reporting success.

New runToFiles() points the child's stdout/stderr at temp files via
Bun.file() (never raw fds — closing self-opened fds around a spawn tripped
Bun's fd bookkeeping into a stray epoll_ctl EBADF), awaits exit, then reads
the files: the kernel has flushed everything by child exit, so the
post-exit read is complete, and chatty children can't stall on a full pipe
buffer. Both handleTest and spawnSkill route through it (timeout + capped
read preserved via timeoutMs/maxStdoutBytes). Bun.spawnSync would also
capture reliably but would deadlock: a spawned skill calls back into this
same daemon on GSTACK_PORT.

The `tests passed for "<name>"` fallback is gone — a passing bun test
always prints a summary, so exit 0 with no output means the run was NOT
captured, and handleTest now throws instead of fabricating success. The
E2E assertion checks both stream halves (banner + summary + "Ran N tests")
instead of the loose alternation whose `tests passed` branch matched the
synthetic fallback vacuously. A static tripwire pins the structure:
runToFiles owns the module's ONLY Bun.spawn, and no site reads child
output via stdout:'pipe' / new Response(proc.stdout) / getReader().

Scope: the PR's repo-wide test-file sweep is deliberately not absorbed —
this is the core only, per the wave plan.

Tests: browser-skill-commands + browser-skills-e2e + browser-skill-write
74 pass, 0 fail.

* feat(browse): allow Emulation.setEmulatedMedia on the CDP allowlist (re-derived from #2419)

Adds Emulation.setEmulatedMedia to the deny-default CDP allowlist:
tab-scoped, trusted output (returns an empty result — no page content).
Unlocks media type/feature overrides (prefers-color-scheme,
prefers-reduced-motion, prefers-contrast, forced-colors) via `$B cdp`, so
dark-mode and a11y CSS branches are testable without a headed toggle. Like
setUserAgentOverride, the override persists on the tab until cleared with
an empty features array — noted in the entry's justification.

Registry test pins the entry (allowed + tab scope + trusted output); the
PR's VERSION/CHANGELOG stamping is stripped per wave convention (versioning
happens at /ship).

* fix(browse): create node bundle output directory

* fix(deps): bun-patch playwright-core 1.62.1 — windowsHide at launch + taskkill (#2160, #1989)

The repo's first patchedDependencies entry. playwright-core's bundled
process launcher (lib/coreBundle.js in the 1.62.x layout) spawns browser
children without windowsHide — Node defaults it to FALSE for
child_process.spawn — so Chromium children could flash a console window on
Windows, and its force-kill path shells `taskkill /pid <pid> /T /F`
through cmd.exe with the same omission. Both sites now pass
windowsHide: true via patches/playwright-core@1.62.1.patch (generated with
`bun patch` / `bun patch --commit`).

Coherence verified end-to-end: rm -rf node_modules && bun install applies
the patch cleanly (both sites present in the reinstalled tree), and a real
chromium.launch() through the patched bundle works.
browse/test/playwright-core-patch.test.ts pins the three-legged invariant
statically — package.json's patchedDependencies key is VERSION-KEYED
against the installed playwright-core, the patch file exists and carries
both sites, bun.lock records the patch, and the installed bundle actually
has it applied — so a future playwright bump that forgets to re-target the
patch fails CI with the exact key to regenerate (revert pairing: dropping
the c25 bump requires dropping this patch too).

Tests: playwright-core-patch 4 pass, 0 fail.

* fix(preamble): probe AGENTS.md for skill routing; team-init resolves GSTACK_ROOT (#2500)

The HAS_ROUTING preamble probe only checked CLAUDE.md, so repos that route
skills via AGENTS.md (the cross-harness convention for Codex, Cursor, and
generic agent hosts) reported HAS_ROUTING: no and got nagged to create
CLAUDE.md. The probe now iterates CLAUDE.md and AGENTS.md.

gstack-team-init's required-mode enforcement (the CLAUDE.md verification
snippet and the generated .claude/hooks/check-gstack.sh) hardcoded
~/.claude/skills/gstack, false-blocking installs living at any other host's
global root or the migrated ~/.gstack/repos/gstack location. Both sites now
resolve the install root: GSTACK_ROOT env first, then every registered
host's globalRoot, then the migrated repo path. Install instructions keep
pointing at the canonical Claude location.

test/routing-probe.test.ts pins both: rendered-preamble assertions plus a
live execution of the extracted probe block (AGENTS.md-only repo => yes),
and a drift test that requires every hosts-registry globalRoot to appear in
team-init's probe list.

* fix(resolvers): empty find must not fall through to cwd (#2483)

find ... | xargs ls -t runs ls with NO operands when find matches nothing —
GNU xargs still invokes the command once, and ls -t with no operands lists
the current directory. Three sites misfired on fresh installs (no ceo-plans /
checkpoints / plans yet), exactly where a wrong answer is least likely to be
recognized: review.ts's plan fallback silently adopted a random cwd .md as
"the plan", and Context Recovery listed unrelated cwd files as RECENT
ARTIFACTS / LATEST_CHECKPOINT.

All three now use xargs -r ls -t, mirroring the shape the sibling
bin/gstack-codex-session-import fix (#2482) landed with: -r pins the BSD
skip-on-empty behavior on GNU too, and BSD xargs accepts -r as a no-op.

test/empty-find-fallthrough.test.ts pins it four ways: no bare xargs ls -t
in scripts/ or bin/, both rendered Context Recovery sites guarded, a live
execution proving an empty checkpoints dir yields no checkpoint (not a decoy
cwd file), and a rendered-SKILL.md sweep.

* fix(codex): retire deprecated web-search flag behind one CODEX_WEB_SEARCH_FLAG constant (#2525)

codex >=0.144 deprecates the legacy --enable-based web_search_cached
spelling (web search is on by default; --enable <FEATURE> now means
-c features.<name>=true, verified against codex 0.147.0's exec --help).
Every gstack codex invocation now passes -c 'web_search="cached"' instead.

The flag previously lived inline at 19 raw sites. Per ENG-OV11a the 10
template-inline sites (autoplan/SKILL.md.tmpl x4, codex/SKILL.md.tmpl x6)
convert to a shared {{CODEX_WEB_SEARCH_FLAG}} token first, so ONE resolver
constant (CODEX_WEB_SEARCH_FLAG in scripts/resolvers/constants.ts) now
covers all sites: review.ts x5, design.ts x3, the token resolver in
utility.ts, and the tool-map helper comment.

codex/SKILL.md.tmpl's web-search prose guarantee is corrected: the -c form
explicitly overrides a top-level web_search config (the legacy flag yielded
to it), and native codex review disables web search regardless of
configuration, so the flag is a no-op on the default Review path.

test/codex-web-search-flag.test.ts is the safety net: repo-wide grep
tripwires assert NO rendered SKILL.md/section/golden and NO source file
carries the deprecated spelling, and that the token resolves in rendered
output.

* fix(question-tuning): interpolate the absolute question-registry path (#2489)

The Question Tuning preamble pointed agents at a RELATIVE
scripts/question-registry.ts in the same sentence whose ${bin} path renders
absolute. Agents run with cwd in the USER'S project — the relative lookup
never resolves, silently fails, and the documented {skill}-{slug} fallback
fabricates a singleton question_id every time (one observed
/plan-eng-review session: 21/21 unregistered ids, so no per-question
preference can ever attach).

The resolver now interpolates ctx.paths.skillRoot the way sibling resolvers
interpolate bin paths: ~/.claude/skills/gstack/scripts/question-registry.ts
on Claude, $GSTACK_ROOT/scripts/question-registry.ts on env-var hosts.

test/question-tuning-registry-path.test.ts asserts the rendered path per
host, forbids the bare relative shape, and checks the target file exists in
the install tree.

* fix(resolvers): slug-canonical branch form in file-path positions (#2550, #1851)

Branch-name-to-filename had incompatible rules across writer and readers:
gstack-review-log WRITES <branch>-reviews.jsonl with the gstack-slug
canonical form (tr '/' '-' then tr -cd 'a-zA-Z0-9._-', bin/gstack-slug:178),
but Context Recovery PROBED it with raw $_BRANCH from git branch
--show-current — so for any branch containing a '/' the REVIEWS line never
fired (#1851's reader half of #1127). The probe now uses ${BRANCH:-unknown},
the canonical value the gstack-slug eval on the block's first line already
sets. review.ts's plan content-search BRANCH gains the missing tr -cd half
so it matches the same canonical pipeline.

Full audit of the 5 raw $_BRANCH interpolation sites in scripts/resolvers/
(E3): generate-context-recovery.ts:16 (reviews.jsonl path) -> canonical
BRANCH; :19/:21 (timeline.jsonl content greps) KEEP raw $_BRANCH because the
timeline writer (preamble's gstack-timeline-log call) stores the raw branch
in the "branch" field — slugging the reader would break that pairing;
generate-preamble-bash.ts:29 (display echo) and :97 (timeline data write)
keep raw by design. The *-$BRANCH-design-*.md family (review.ts:313 + 3
plan-review templates) is a consistent tr '/' '-' writer/reader pair and is
deliberately untouched.

test/branch-slug-hygiene.test.ts pins the discipline: a rendered-output
sweep forbids raw $_BRANCH adjacent to a path separator or as a filename
prefix in ANY generated SKILL.md/section, and a live round-trip on a
feat/slash branch proves gstack-review-log's write is found by the rendered
probe (with the raw-form shape as a negative control).

* fix(ship): review fix loop stays in one invocation, bounded at 3 cycles (#2391)

The pre-landing review committed its fixes, then STOPPED and told the user
to run /ship again — 5-10 manual invocations on a branch with a few
auto-fixable findings, violating /ship's fully-automated contract. There is
no user decision between those invocations; each rerun just repeats the
workflow until a review pass produces no fixes.

ship/sections/review-army.md.tmpl item 7 now makes the loop explicit: after
committing fixes, re-run the test suite (Step 5) and this review (Step 9
items 2-6) in the SAME invocation, repeating until one full pass applies
zero fixes, then continue to Step 12. Bounded at 3 fix cycles — a review
that will not converge STOPs with a report of which findings keep
reappearing (a genuine blocker), never with a rerun request.

test/ship-review-loop.test.ts asserts no rendered ship surface (section +
all three host goldens) carries the STOP-and-rerun shape and that the
bounded loop language renders.

* feat(codex): model round-trip probe — an unusable configured model fails fast with guidance (#2477)

The auth probe accepts 'auth exists' as readiness, but a ChatGPT account
with a stale model pin in ~/.codex/config.toml passes it and then EVERY
mode dies with an HTTP 400 ('The <model> model is not supported when using
Codex with a ChatGPT account') and no pointer to where the model came from
— one report burned ~40 minutes and four invocations plus a strings dump
of the binary before finding the one-line config fix.

bin/gstack-codex-probe gains _gstack_codex_model_probe: a short
codex exec 'reply OK' round trip with the configured model, gated behind
the cheap auth probe at all three preflight sites (codex Step 0.5, the
shared codexPreflight in scripts/resolvers/constants.ts — which grows a
model_unusable CODEX_MODE branch — and autoplan's availability chain).
Verdicts: MODEL_OK (cached 1h, keyed on config.toml + auth.json mtimes so
a pin edit or re-login re-probes immediately), MODEL_UNUSABLE (exit 1,
prints the rejection plus HINTs at the model= pin and the
[notice.model_migrations] table), MODEL_PROBE_INCONCLUSIVE (timeout or
transient: FAIL-OPEN so network luck never wedges codex mode).

The 'Model not supported (HTTP 400)' Error Handling entry already shipped
in v1.64.0.0; Step 0.5's prose now routes MODEL_UNUSABLE to it.

test/codex-model-probe.test.ts drives all four behaviors against a stubbed
codex binary (invocation-counted cache hit, hint content, fail-open
polarity, mtime invalidation).

* fix(review): skip nested codex spawns when already running under a Codex host (#2519)

/review executed inside a Codex host spawned the codex specialist passes
anyway — the same model reviewing itself, at multiplied cost (observed:
15M tokens for a single /review).

Detection per maintainer decision 7: a presence probe of the Codex session
env. A live Codex session exports CODEX_THREAD_ID and CODEX_SANDBOX into
every shell it spawns — verified during implementation against a live
`codex exec 'env | grep -i codex'` capture on codex 0.147.0
(CODEX_THREAD_ID, CODEX_SANDBOX=seatbelt, CODEX_SANDBOX_NETWORK_DISABLED=1,
CODEX_CI=1). The shared codexPreflight in scripts/resolvers/constants.ts
(consumed by all three review.ts army blocks: adversarial, codex plan
review, codex doc review) now yields CODEX_MODE=under_codex and instructs
exactly one printed notice — '[running under Codex — nested codex passes
skipped; set GSTACK_FORCE_CODEX_REVIEW=1 to force]'. The override env var
forces the nested passes for users who really want them. codex/SKILL.md.tmpl
Step 0.5 gains the same probe: /codex under a Codex host stops with a
one-line notice, since its whole value is a SECOND model's opinion.

test/codex-under-codex-detection.test.ts runs the rendered preflight bash
under all four env combinations (thread-id only, sandbox only, forced,
clean) and asserts the probe + notice render in the three preflight
consumers and the codex skill.

* fix(test): update four main-side gen-skill-docs assertions to the T6 contracts

Three contracts moved under this theme and the assertions pinned the old
shapes:

- The routing-probe assertion expected the single-file
  'grep ... CLAUDE.md' shape; #2500 made the probe iterate CLAUDE.md AND
  AGENTS.md, so it now asserts the for-loop + quoted $_RF shape.
- The three Claude-output Codex-path bans tripped on ~/.codex/config.toml,
  which the shared codexPreflight's model_unusable branch (#2477) now
  documents in rendered output. That path is the Codex CLI's own config
  file — the same user-facing class as the already-exempt
  ~/.codex/sessions/ — so it is scrubbed before the host-path ban, with the
  reasoning recorded next to the existing exemptions.

this phase", but gbrain's only emitters are the CONTENT phases
(extract_atoms, synthesize_concepts) — which the default base packs
legitimately skip while resolve_symbol_edges still runs. Every base-pack
brain therefore got the pack-capability WARN with its wrong, costly
remediation ("switch schema packs"), masking real graph problems. The match
now anchors to the graph phase (resolve_symbol_edges/extract_code_symbols);
a base-pack run with a built graph is clean, and a resolved-0 run gets the
honest 0-edge diagnosis.

* fix(setup): install office-hours into the external-host runtime roots

Fixes #2449. plan-eng-review's inline office-hours step reads
$GSTACK_ROOT/office-hours/SKILL.md, but the codex/factory/opencode runtime
roots never installed it — the documented path pointed at nothing on every
external-host install (Codex on Windows was the reported repro). Each
runtime-root creator now links its host-rendered gstack-office-hours
SKILL.md at office-hours/SKILL.md.

* fix(gbrain-install): name the real fix when an npm-installed bun breaks the shim

Fixes #2487. `npm i -g bun` puts POSIX/cmd/ps1 shims on %PATH% but never
bun.exe — and the gbrain.exe shim that `bun link` generates resolves bun.exe
specifically, so link succeeds and every gbrain call dies with bun's
misleading "bun is not installed in %PATH%" (which suggests installing a
second parallel bun). The D19 validation failure paths now detect the
condition on Windows and print the actual remediation: bun's own
process.execPath IS the hidden bun.exe — add its directory to PATH.

* docs(ios-qa): document the bridge compatibility preflight and non-SwiftPM fallback

Re-derived from PR #2581 under the generated-file screening rule (template
hunk taken; SKILL.md regenerated). Prevents the agent from inventing project
wiring on apps the bridge doesn't support (ObservableObject-style or
non-SwiftPM apps): the preflight now names the compatibility check and the
manual fallback path.

* fix(deps): force adm-zip past CVE-2026-39244 via an override

Re-derived from PR #2485 as a resolution override rather than its direct-dep
bump: adm-zip reaches the tree only transitively (onnxruntime-node pins
^0.5.16), so a top-level copy at 0.6.0 would leave onnxruntime-node loading
the vulnerable 0.5.17 — which is exactly what the scanner PR's own lockfile
showed. The override forces every resolution to ^0.6.0.

* deps: remove unused puppeteer-core; bump transformers/marked/socks

Completes the #2582 split (ENG-OV8). puppeteer-core had ZERO imports
repo-wide — a dead direct dependency whose only footprint was its CVE-prone
transitive chain (puppeteer-core > @puppeteer/browsers > proxy-agent >
get-uri > basic-ftp) and the pin test + basic-ftp override that existed
solely to guard it. Removing the dependency removes the surface: the
basic-ftp override and test/basic-ftp-security-pin.test.ts retire with it
(the lockfile resolves zero basic-ftp copies now). transformers ^4.2.0,
marked ^18.0.9, socks ^2.8.9 land per the dependabot group, gated on the
ONNX sidecar load+classify smoke passing with the bumped transformers
(28/28 sidecar+classifier+security tests green post-bump).

* fix(test): scope rendered-output tripwires to repo sources; stop cdp-e2e's env leak

Two hermeticity holes surfaced by the wave's final gate. (1) The three T6
tripwires (branch-slug, codex-flag, empty-find) enumerated the whole tree
including the workspace-local .claude/ install, which is not generated
output and can carry dangling symlinks from unrelated sessions — one ENOENT
there failed all three. They now scan repo sources only. (2)
browse/test/cdp-e2e.test.ts mutated process.env.GSTACK_HOME at module scope
without restore; in one-process shard runs that leaks into every later test
file — observed baking cdp-e2e's temp render path into artifacts that
outlived it (53 dangling SKILL.md symlinks in a workspace install). The
original value is now restored in afterAll. The exact test that performed
the polluted relink remains unattributed; both known leak vectors are
closed and the workspace was repaired via an explicit gstack-relink.

* fix(test): honest budget for the suite's one headed persistent-context launch

The launchHeaded/handoff parity test cold-launches a HEADED Chromium — 8-25s
on macOS, worse on the first launch of a freshly downloaded bundle (XProtect
scans it, the #2554 class) and under shard concurrency. bun's 5s default made
it the suite's most reliable false negative: it timed out identically on the
pre-wave baseline run of pristine main. 45s budget; passes 15/15.

* fix(test): assemble redact fixtures at runtime — the guard caught its own wave

The pre-push redact guard BLOCKED this branch's first push: the wave's new
scan-range tests carried live-FORMAT fake credentials as literals (3 AWS key
shapes + a password-bearing DB URL), and the guard scans pushed diff bytes.
Same dogfood moment as the v1.64 wave, same rule: assemble the fixture at
runtime so the diff never carries a credential shape, never bypass the guard.
Runtime strings stay live-format for the hook under test. The guard works.

* fix(test): sync ios-qa fixture mirrors with the #2585 DEBUG-guard templates

The #2585 absorb updated DebugBridgeTouch.m.template and
Package.swift.template but not their FixtureApp mirrors, failing the
template↔fixture parity gate. DebugBridgeTouch.m syncs byte-for-byte; the
fixture Package.swift takes only the template's new cSettings DEBUG define on
the Touch target (the fixture's own testTarget is fixture-only content the
parity normalization deliberately ignores — a naive full copy breaks the
XCTest invariant). 23/23 including the real swift build.

* fix(slug): env-override runs never persist to the cwd cache; cache is GSTACK_HOME-aware

Found while closing the wave's eval gate: a test exporting
GSTACK_PROJECT_SLUG from the repo root persisted the override into the cwd
slug cache, silently rebinding the ENTIRE repo's session state (evals,
decisions, timelines) to the test's slug for every later env-less run. The
escape hatch is per-invocation by contract — it no longer writes the cache.
The cache dir also hardcoded $HOME while lib/bin-context.ts's native port
(#2561) reads it GSTACK_HOME-aware, so temp-home test runs littered the real
~/.gstack (observed: 2,528 stale temp-cwd entries, swept). Writer and reader
now key the same GSTACK_HOME-aware cache; regression tests pin both
behaviors.

Also raises the cso --diff eval budget (240s/25t → 360s/40t):
transcript-verified, the wave's legitimately-grown audit session completes
the report and dies in closing telemetry at ~215s under the old budget; the
full-audit sibling already runs at 300s.

* fix(test): pin GSTACK_HOME in the slug walk-up cache tests

The cache dir became GSTACK_HOME-aware; these tests seed and assert cache
files under a temp HOME but spread the ambient env, so a sibling test
leaking process.env.GSTACK_HOME in a shared-process shard pointed the bin at
a different cache than the one under assertion (AC-2/AC-6 failed in shard
context, passed solo). The env now pins GSTACK_HOME to the temp home —
verified identical results with and without a simulated ambient leak.

* fix(test): the cache-hygiene test strips ambient GSTACK_PROJECT_SLUG

Its env-less contract must be env-less: any ambient override leaking into a
shared-process shard flips the run into override mode, which correctly skips
the cache write the test asserts.

* fix(test): ratchet ship's skeleton cap for the v1.66.1 merge union

Merging main's v1.66.1.0 (evidence-ledger prose in ship's template) on top of
the wave's growth lands ship at 90,333 bytes, 333 over its cap. Re-measured
per the ratchet protocol: cap 90,800.

* fix(brain-sync): throttle + bound the detector push; empty-queue fast path

Review-army findings on the #2549 detector. (1) The preamble runs --once at
every skill boundary, so an unthrottled retry paid a full network push
attempt per boundary in exactly the steady states it targets (offline,
broken auth) — a captive-portal push can block 30-75s against the header's
"<1s when idle" promise. Attempts now stamp .brain-last-push-attempt and
retry at most every 10 minutes; the push never prompts (GIT_TERMINAL_PROMPT=0)
and bounds stalled transfers via git's low-speed limits (portable — stock
macOS has no timeout binary). (2) Author-scoped: only gstack-brain-sync's own
commits retry; a user's manual commit in ~/.gstack rides along on real drains
as before, never auto-published by the detector. (3) Empty-queue fast path
exits before the compute/rewrite python spawns — the steady state is now
cheaper than the pre-wave truncation code. (4) The queue rewrite warns on
failure instead of silently letting the status claim a drain that didn't
happen, counts held unparseable lines, and collapses duplicate lines on
rewrite. Throttle + delivery matrix cases added (37/37).

* fix(version-bump): JSON version-paths get the npm translation; honest recovery messages

Review-army findings. A repo whose package.json carries the legacy 4-digit
mirror and pins it via .gstack/version-path would get "1.67.0.1" written into
a manifest npm rejects forever, with no drift state to catch it (a JSON
source is self-consistent by construction) — the JSON branch now writes the
npm-valid translation, warns when translation occurred, and surfaces the
requested form. Lockfile-failure messages now match reality per failure
point: classify never reads lockfiles, so "re-run and repair" was a false
promise when package.json was written and only the lockfile threw. Both
malformed-version messages read MAJOR.MINOR.PATCH[.MICRO], matching the
3-digit contract this wave ships.

* fix(extension): remove the orphaned security-banner block; repair two dead CSS tokens

Design-review findings. The 197-line .security-banner component (incl. its
keyframes) had no producer — no JS has created the element since the
chat-path rip, the same dead-hidden-security-UI class as the #2557 shield
this wave removed; a tombstone comment points at git history if the banner
UX returns. Two pre-existing token bugs in the mem-toast styles: --zinc-700
was never defined so the button hover computed to transparent (now carries a
fallback), and --font-sans doesn't exist (now --font-system, which :root
defines).

* fix(brain-sync): detector pushes only when ALL unpushed commits are its own; lock released on every exit

The unpushed-commit detector's author check was existential: any bot-authored
commit in origin/<branch>..HEAD armed a push of HEAD, silently publishing
interleaved user-authored commits in ~/.gstack. Now the gate requires the
author-scoped count to equal the total unpushed count — one user commit
disables the autonomous retry entirely (user commits still ride along when a
real drain pushes). Detached HEAD is excluded (origin/HEAD usually resolves,
making the retry a 10-minutely doomed push).

The lock-release trap now installs immediately after lock acquisition instead
of after the empty-queue fast path — the steady state at every skill boundary
leaked the lock dir and relied on stale-PID detection, which PID reuse defeats.
An INT during the detector's network push is covered too.

Matrix test: interleaved user commit blocks the detector, then a real drain
delivers everything.

* fix(version-bump): version-path and package-json-path pins cannot escape the repository

.gstack/version-path and .gstack/package-json-path are repo-controlled
content. A cloned repo pinning '../../victim.json' — or an in-repo symlink
pointing outside — turned a routine bump into an arbitrary file overwrite
outside the repository. assertRepoContained rejects absolute paths, lexical
.. escapes, and symlink escapes (deepest existing ancestor realpath'd, so a
not-yet-created VERSION file is checked through its parent). Lockfiles that
are symlinks resolving outside the repo are skipped with a warning instead
of written through.

Six containment tests including the not-over-broad control (subdirectory
pins keep working).

* fix(browse): port allocator range actually stays below the ephemeral floor; terminal-agent retries a raced bind

RANDOM_PORT_MAX was 60000 while the module header documents 49152-65535 as
the pool to avoid — ~22% of allocations landed back inside it, preserving
the phantom-404 squatting class for both the daemon and the weeks-lived
terminal-agent. The cap is now 49151 and the range test pins the true
property (< 49152) instead of the old <= 60000 tautology.

terminal-agent boot also re-allocates and retries up to 5 times when
Bun.serve throws in the probe-then-bind TOCTOU window — previously a
concurrent bind killed the boot with no retry via main().catch → exit 1.

* fix(codex-probe): bash-native watchdog when no timeout binary exists; negative-cache the deterministic model 400

Stock macOS ships neither coreutils gtimeout nor timeout(1); the wrapper's
fallback ran the command unwrapped, so a hung codex exec blocked the probe
and the calling workflow indefinitely. The fallback now backgrounds the
command, TERMs it at the deadline, and mirrors timeout(1)'s exit-124
contract — with the watchdog's stdout detached so an early finish never
blocks a caller's $(...) capture on the orphaned sleep.

MODEL_UNUSABLE is now negative-cached for 15 minutes (same exit-1 + hints
from cache). The deterministic 400 is config-driven, so re-probing every
preflight charged the affected user a 30s round trip plus real tokens per
review section, forever. Editing config.toml — the fix — changes the cache
signature and re-probes immediately; MODEL_PROBE_INCONCLUSIVE stays uncached.

* fix(browse): xprotect heal resolves the install root via os.homedir and keeps guidance on a failed retry

With HOME unset, the global-install candidate became the RELATIVE path
.claude/skills/gstack under the daemon's cwd — often an untrusted repo being
QA'd, whose planted node_modules would then be where the heal runs the
playwright install (repo-controlled code execution). os.homedir() plus an
absolute-or-skip guard closes the class.

launchWithXProtectHeal also wraps the post-heal retry: a second classified
failure previously propagated raw, dropping the manual-remediation guidance
exactly when the automatic path had just proven insufficient.

* fix(make-pdf): --strict and --confidential join BOOLEAN_FLAGS; the guard test derives the set from source

Both flags are read as '=== true' booleans but were missing from
BOOLEAN_FLAGS, so 'generate --strict essay.md' still ate essay.md as the
flag's value — the exact #2514 failure the set exists to prevent. The
completeness guard hardcoded six names and could not catch it; it now
derives every boolean read from cli.ts itself (direct reads plus
booleanFlag pairs), so the next boolean flag fails the suite until it
joins the set.

* fix(uninstall): provenance-gate the shape-2 and cursor sweeps; document the alias-name coupling

Three ways gstack-uninstall could touch a user's own skills:

- Shape 2 (real dir + symlinked SKILL.md) matched the link target against a
  bare *gstack* substring, so a skill symlinked from ~/tools/gstack-fork/ was
  wiped on uninstall. The gate now requires "gstack" as an anchored path
  segment (gstack/*|*/gstack/*, same pattern as shape 1) AND the dir name in
  gstack's skill inventory (parity with shape 3); anything else is listed to
  stderr, never deleted.
- The new Cursor removals (~/.cursor/skills/gstack* and repo-local
  .cursor/skills/gstack*) rm -rf'd any glob match with no provenance check,
  so a hand-written ~/.cursor/skills/gstack-fork-notes was swept. Real dirs
  now require the AUTO-GENERATED banner in SKILL.md; non-matching dirs are
  kept and listed. Legacy codex/factory/kiro globs are untouched (tracked in
  TODOS as a follow-up).
- The _INVENTORY seed list hardcodes alias names created by setup's
  _install_alias_skill_md; both sites now carry mirrored keep-in-sync
  comments so a renamed alias can't silently strand its dir.

The skipped-entry report moves to the end of the run so cursor skips are
listed alongside the Claude ones.

* fix(redact): env.kv stops flagging cacheKey-style names; prepush exclusion scoped to the push remote

Two calibration/coverage fixes in the redaction guard:

- env.kv's zero-or-more-prefix regex fired on ANY identifier ending in a
  credential suffix, so ordinary code (cacheKey:, sortKey:, partitionKey:,
  hotkey:, even monkey:) with an 8+-char entropic value hit a MEDIUM confirm
  prompt — a gate that cries wolf gets ignored. A name now only counts when
  its shape is credential-semantic: suffix separated by _/-/. (api_key,
  x-access-key, AUTH.TOKEN), a bare suffix (key:, token:), ALL-CAPS env style
  (APIKEY=, MY_APIKEY=), or a camel compound with a credential prefix
  (apiKey, authToken, clientSecret). The value stays capture group 1, so the
  shape check lives in validate (isCredentialShapedEnvName), not the regex.

- gstack-redact-prepush's narrowing excluded commits reachable from ANY
  remote (`--not --remotes`), so a secret that had only ever reached a
  private/local-path remote was never scanned when later pushed to a PUBLIC
  remote. The exclusion is now scoped to the push target
  (`--remotes=<name>/*`) via the remote name git hands pre-push as $1 (the
  installed wrapper already forwards "$@"); stdin/CLI invocations and URL
  pushes without a configured name fall back to the historical all-remotes
  behavior. #2592's catch-up-merge fix is unaffected: upstream commits come
  from the same remote being pushed to.

New coverage: env.kv negative controls (cacheKey/sortKey/partitionKey/
hotkey/monkey/idempotencyKey) + positive controls for all four name shapes;
end-to-end hook tests proving a second-remote secret blocks a push to origin
while origin-published catch-up content still doesn't, plus both fallbacks.

* fix(browse): honest probe budget, bounded daemon log, single refusal source, liveness + reinstall coverage

Five hardening items in the browse CLI and its tests:

- probeHealthWithBackoff's advertised ~8s budget could really run ~10s: the
  final 2s probe could start 1ms before the deadline, and every call site
  had JUST run a failed probe yet the loop re-probed immediately.
  Iterations now start with the sleep and each probe's timeout clamps to
  the remaining budget (isServerHealthy takes an injectable timeout).
- browse-daemon.log is append-mode across every respawn with no size cap,
  so a crash-respawn loop fills the disk. The path is now built in one
  place (daemonLogPath — the Unix fd path and the Windows launcher string
  had two spellings) and daemon start rotates a >10MB log to
  browse-daemon.log.1, single generation, matching the repo's 10MB
  rotation convention. Rotation is exported + injectable and behaviorally
  unit-tested.
- The two "healthy daemon already running" refusal blocks in connect had
  already drifted (one lost the tabs/cookies/logins explainer) — extracted
  refuseHeadedOverLiveDaemon as the single source.
- process-liveness: pinned the EPERM-means-alive contract (PID 1 on POSIX,
  PID 4 on Windows — signalable-or-EPERM, both alive). A probe that reads
  EPERM as dead is the false negative that leaked agents.
- runBoundedChromiumReinstall had zero coverage: now exercised end-to-end
  against a stub bunx on a prepended PATH — exit 0, install-exit-N with
  stderr tail, the detached group-kill timeout path (child of the child
  dies too), and spawn-error.

* fix(hooks): timeline Stop hook reads a 256KB tail instead of the whole file

The Stop hook runs on EVERY Claude Code turn machine-wide and re-read +
JSON-parsed the entire timeline each time, scaling to the 10MB size cap
(~100-300ms per turn of pure overhead). It now reads only the last 256KB
via fstat + positioned read, discarding the first partial line when the
window starts mid-file.

Semantics: a dangling "started" older than the last 256KB of appends
belongs to a session long gone — beyond repair interest. The window can
never fabricate a dangling entry ("completed" is always appended AFTER its
"started", so any started inside the window has its completion inside the
window too), so idempotency holds. The fail-open contract is unchanged:
exit 0 always, size cap kept, deadline re-checked before the write.

New test: a >256KB timeline where a recent dangling entry still gets
repaired while an old out-of-window dangler is left alone; all existing
fail-open cases pass unchanged.

* fix(setup): Windows runtime-asset copies prune nested gitignored build output

_link_skill_runtime_assets' exclusion list filters DIRECT children only, so
the Windows cp -R real-copy path swept NESTED gitignored build output into
the installed skill dirs — concretely, ios-qa/scripts/gen-accessors-tool/
.build is 252MB per install. The IS_WINDOWS real-copy branch now prunes
nested node_modules/.build/dist post-copy (find -prune -exec rm -rf).

Scoped to _link_skill_runtime_assets ONLY: the generic _link_or_copy stays
untouched because runtime roots (browse/, design/) intentionally copy their
dist/ binaries. On Unix the assets are symlinks into the working tree, and
the prune is gated on the real-copy shape so it can never delete build
output from the repo through a link — both directions pinned in
test/setup-windows-rerun-refresh.test.ts with fixture trees.

* fix(upgrade): migrations see the real install dir; stash can no longer resurrect stale renders

Two ways the v1.67 render-dirt cleanup was inert in the wired upgrade flow:

- Both migration runners invoked `bash "$migration"` without
  GSTACK_INSTALL_DIR, so migrations that clean the INSTALL (v1.67.0.0.sh
  defaults to ~/.claude/skills/gstack when unset) silently no-oped for
  repo-local installs. setup now passes "$SOURCE_GSTACK_DIR" and the
  /gstack-upgrade Step 4.75 runner passes the detected "$INSTALL_DIR".
- /gstack-upgrade Step 4 ran `git stash` BEFORE reset+setup, so the tree
  was always clean by the time the migration ran, the legacy render dirt
  landed in stash@{0}, and Step 4's own note then told the user to
  `git stash pop` — restoring stale generated SKILL.md over the fresh
  checkout permanently. Step 4 now discards the render footprint
  (generated SKILL.md and sections/*.md modifications only, the same
  classification as migrations/v1.67.0.0.sh) BEFORE stashing, so the stash
  only ever carries real user changes; the stash-pop note says the render
  dirt was discarded and regenerates. The migration stays for manual
  git-pull flows.

Template change regenerated for all 3 hosts (claude tree checked in;
codex/factory trees are gitignored render outputs).

* fix(browse): stop --force-restart kills the live daemon directly instead of booting a fresh one

`browse stop --force-restart` on a live-but-busy daemon fell through the
stop short-circuit into ensureServer(), whose force-restart path kills the
daemon and then STARTS A FRESH ONE (daemon + Chromium, multi-second churn)
just so sendCommand('stop') can shut it down again — the #2254 churn in
force clothing. gstack-upgrade's Step 4.8 sends users down exactly this
path when a stale daemon is busy after an upgrade.

The stop short-circuit now handles it: live pid + --force-restart → kill
the daemon (tree-kill on Windows, TERM→KILL on POSIX), reap the orphaned
Chromium + clear profile locks, remove the state file, exit 0 — no server
is ever started. Pinned in stop-dead-daemon.test.ts: a wedged live "daemon"
is killed, the state file stays gone (a booted daemon would have rewritten
it), and no Starting/Restarting output appears.

* fix(hooks): timeline repair counts started vs completed per key instead of set-masking

The dangling-event repair kept only the FIRST "started" entry per
skill+session key and treated "completed" as a set, so any key where one
run completed and another dangles was never repaired — and keys are not
unique per run: legacy entries with no session field all share the
bare-skill key, and the preamble's "$$-epoch" session ids collide within
the same second. One old completion masked every future dangler forever.

The hook now counts started vs completed per key and appends completions
for the DIFFERENCE. Idempotency holds by construction: the appended
completions balance the counts, so the next Stop appends nothing. Pinned
with the two-runs-one-dangling case plus a re-run no-op assertion; all
existing fail-open cases pass unchanged.

* fix(setup): Windows refresh bypass no longer deletes a user's own skill dirs

The #2444 IS_WINDOWS refresh bypass (link_codex/factory/opencode/cursor
_skill_dirs) rm -rf's the destination before re-copying — and the host
skills dirs are SHARED namespaces, so the gstack* glob can land on a
user's OWN real directory (e.g. ~/.cursor/skills/gstack-notes). Every
./setup re-run silently deleted it — the ownership guard the comments
still claimed (#2142). The sidecar installers had the same shape against
a hand-written skill squatting on the canonical .../skills/gstack root,
and create_cursor_runtime_root wiped that root unconditionally on every
platform.

Same provenance model as bin/gstack-uninstall (#2563):

- _owned_for_windows_refresh: a real dir is only replaced when its
  SKILL.md carries the AUTO-GENERATED banner; symlinks and missing
  targets always pass. Non-matching dirs are kept and listed to stderr.
  Wired into all four *_skill_dirs loops.
- _sidecar_root_user_owned: a root whose SKILL.md exists WITHOUT the
  banner is the user's — create_agents_sidecar, create_cursor_sidecar,
  and create_cursor_runtime_root skip it entirely instead of writing
  into (or wiping) someone else's skill. A root with no SKILL.md stays
  presumed ours (the documented install location; old/partial installs
  look like that).

Pinned by a static census (every bypass site must carry its gate) plus
behavior fixtures: a bannerless user dir survives the Windows re-run
while a bannered install still refreshes, and a squatted sidecar root is
left untouched.

* fix(render): a failed brain-aware render can no longer vanish the installed skill set

Both render sites (setup's gbrain step and gstack-config gbrain-refresh)
ran `rm -rf` on the LIVE render dir BEFORE invoking gen:skill-docs:user.
Installed skills symlink into that dir (relink prefers it), so one
transient render failure — bun error, disk full, broken template — left
every brain-aware skill's SKILL.md symlink dangling: the whole skill set
vanished from Claude Code until a successful re-render.

Both sites now render into "$RENDER_DIR.tmp.$$" and swap it in only on
SUCCESS via a shared-contract _swap_in_render helper (mv old away, mv tmp
in, drop old — links into the live path stay valid because the path never
changes). The failure branch removes only the tmp dir and says so: the
previous render, and every link into it, stays fully intact. The
deliberate wipe on the gbrain-GONE path (stale render shadowing canonical
files) is unchanged.

Pinned in test/user-render-out-dir-install.test.ts: static shape (render
targets the TMP dir, never the live dir), _swap_in_render driven
behaviorally from BOTH files, and an end-to-end failure-branch fixture
proving a pre-existing render plus an installed symlink survive a failed
render.

* test+docs: codex probe cache invalidation coverage, make-pdf --no-* structural pin, file the review-batch deferrals

- test/codex-model-probe.test.ts: the 1h TTL and the auth.json half of the
  mtime signature had no coverage — a regression in either would silently
  serve a stale MODEL_OK after re-login or forever. Added TTL-expiry
  (backdated cache line re-probes) and auth.json-mtime invalidation cases,
  mirroring the existing config.toml case.
- make-pdf/test/cli-args.test.ts: structural assertion derived from the
  commands.ts registry — every --no-* flag must be in BOOLEAN_FLAGS, so a
  new negation flag can't silently re-open #2514 (swallowing the next
  positional).
- TODOS.md: filed five review-batch deferrals under the v1.67 queue with
  rationale and effort: setup host-function dedup, cmd.exe %VAR% quoting in
  gbrainInvocation (cross-spawn direction), make-pdf flag registry metadata
  (derive BOOLEAN_FLAGS), legacy codex/factory/kiro uninstall provenance
  gating (parity with the cursor gate), and cursor auto-detect breadth
  (product call).

* fix(test): package.json version check accepts the decision-11 npm translation

The bump wrote the npm-valid 3-digit manifest version for the first time
this release; the old assertion demanded byte-equality with the 4-digit
VERSION. Accept the translation plus the grandfathered pre-v1.67 mirror,
matching gstack-version-bump's own drift contract.

* fix(ci-image): the dependency layer carries patches/ — bun install needs the patch files the lock declares

bun.lock's patchedDependencies (playwright-core windowsHide) made
'bun install --frozen-lockfile' fail inside the image build: the Dockerfile
copied package.json + bun.lock but not patches/. The image-tag hash in all
three workflows (ci-image, evals, evals-periodic — kept in lockstep) now
includes patches/** so editing a patch rebuilds the layer instead of
serving a stale cache.

Verified: the exact COPY set (package.json + bun.lock + patches) installs
clean in a Linux container; without patches it reproduces the CI failure.

* fix(codex-probe): cache signature uses GNU-first stat with numeric validation

On GNU stat, -f means FILESYSTEM mode — the BSD-first form emitted a
multi-line filesystem block on Linux, so the cache signature never matched
its own cache line and the model-probe cache missed on every read (each
preflight re-paid the probe). Same class and same fix as #2195: GNU -c %Y
first, BSD -f %m fallback, non-numeric residue coerced to 0.

Verified: the probe test file passes 7/7 under real GNU stat in a Linux
container (it failed 2/7 on Linux CI before).

* fix(test): first cross-platform run of the wave's tests — Linux tmp portability + Windows-lane truthfulness

Four platform holes from the lanes' first full run over the v1.67 tests:

- uninstall neutral-root fallback hardcoded /private/tmp (macOS-only) and
  ENOENT'd on Linux CI, where the shard TMPDIR is the gstack-containing
  path that forces the fallback — now realpath'd literal /tmp.
- uninstall's kept-and-listed assertion demanded a backslash path on
  Windows while the bash uninstall prints POSIX paths — now
  separator-insensitive.
- setup-rerun's IS_WINDOWS=0 sub-case and the iron rule's force-restart
  consent path are Unix-shaped by construction (Git Bash ln -snf copies
  without Developer Mode; the consent path boots a real replacement daemon
  the browserless Windows lane cannot host) — gated off win32 with the
  reasons in place; the Windows-relevant halves still run there.
- codex-under-codex-detection drives rendered bash under a hardcoded POSIX
  PATH, so every case saw empty output on Windows — moved to
  KNOWN_WINDOWS_INCOMPATIBLE with the run receipt.

* fix(ci-image): stage patches/ into the narrow build context in all three workflows

The image builds from context .github/docker, into which a staging step
copies package.json + bun.lock — the previous fix added COPY patches to the
Dockerfile but not patches/ to that staging, so buildx failed computing the
COPY checksum ('/patches: not found'). All three workflows (ci-image, evals,
evals-periodic) stage identically, in lockstep with the shared tag hash.

Verified: a build over the exact staged context resolves both COPY layers.

* fix(hooks): nest freeze/careful permissionDecision under hookSpecificOutput

Claude Code ignores a top-level permissionDecision, so the /freeze deny and
/careful ask guards silently allowed everything. Nest both under
hookSpecificOutput with permissionDecisionReason, update the shape-blind
tests to pin the nested form, and document the constraint in both skill
templates (regen included).

Closes half of #1459 (freeze enforcement chain).

dedicated team-init fix).

* fix(team-init): required-mode hook blocks with nested schema + exit 2

The generated check-gstack.sh emitted a flat permissionDecision payload and
exited 0, which Claude Code ignores — required mode enforced nothing. The
generated hook now nests the deny under hookSpecificOutput and exits 2 so
the block holds even if the JSON schema drifts again. Adds a temp-repo
regression test that runs the generated hook under both installed and
missing-gstack homes.

Fixes #2413, #2296.

* fix(careful): close three check-careful bypasses via real JSON extraction

The grep-based command extractor stopped at the first escaped quote, so any
quoted argument truncated the command before the pattern checks ran —
`git commit -m "wip" && rm -rf /` was silently allowed. Replace it with a
python3/node JSON parse that fails CLOSED on unreadable payloads, add an
IFS/base64-to-shell obfuscation tripwire, and stop multi-line commands from
riding the single-line safe-exception whitelist (line-based grep would have
approved `rm -rf /` when a later line matched node_modules — a hazard the
real newline decoding exposed).

Contributed by @wtamminga (PR #2426; the -R hunk was dropped — it landed in
v1.61.0.0 — and output shapes updated to the nested hookSpecificOutput form).

* fix(review,autoplan): require explicit run_in_background: false on specialist agents

Claude Code v2.1.198 made subagents run in the background by default, which
inverted the old "do not use the flag" guidance: review-army specialists and
autoplan dual voices silently launched in the background and the merge step
could proceed before they completed — regressing the #497 fix. The generated
guidance now instructs an explicit run_in_background: false, and a static
tripwire fails the free suite if the inert inverted phrasing ever returns to
any generated SKILL.md.

Fixes #2440.

* fix(investigate): anchor the scope-lock freeze hook on $HOME, not CLAUDE_SKILL_DIR

The investigate skill's PreToolUse hooks and Scope Lock probe resolved
check-freeze.sh via ${CLAUDE_SKILL_DIR}, which does not exist when
frontmatter hooks run — the || exit 0 tail then failed open, so the debug
scope boundary silently never engaged (#1871 follow-up). Anchor all four
sites on $HOME/.claude/skills/gstack/ like careful/freeze, and add a static
test asserting no frontmatter command: line in the guard-family skills ever
references CLAUDE_SKILL_DIR again.

Fixes #2469; closes the last live half of #1459 together with the
freeze/careful hookSpecificOutput fix. The broader portable-install-root
rewrite stays #1882 (its own focused PR per the TODOS.md decision).

Reported with a fix by @maxpetrusenkoagent (PR #1873; absorbed narrowly —
the cwd-walk rewrite belongs to #1882).

* fix(redact): scan large diffs in line-aligned slices; stop digit-UUIDs matching as cards/phones

The prepush guard blocked any push whose added lines exceeded the engine's
1 MiB cap with engine.input_too_large — a size error naming no credential —
which trains people onto GSTACK_REDACT_PREPUSH=skip. Scan in 768 KiB
line-aligned slices instead (no pattern is multi-line, so a boundary cannot
bisect a secret); a single oversized line still goes to the engine intact and
fails closed. Also suppress card/phone matches whose span sits ENTIRELY
inside a UUID — digit-only UUID fixtures were 14 of 21 MEDIUM findings on an
ordinary branch, the noise level that stops people reading MEDIUM at all.

Fixes #2304.

* fix(redact-prepush): resolve the real push base instead of EMPTY_TREE whole-repo scans

When the remote default branch is not main/master (or origin/HEAD is unset),
the merge-base guess failed and the hook fell back to scanning the ENTIRE
repository as added lines — re-attributing long-pushed secrets to the
current push and, on any real repo, tripping the engine byte cap so the push
blocked having scanned nothing. Derive the base from commits reachable from
no remote-tracking branch, keep the empty-tree path only for genuinely fresh
repos, and split the block message so an unscannable diff is reported as
"could not scan (fail closed)" rather than "credential found — rotate it".

* fix(redact-prepush): preserve the trailing newline handed to chained pre-push.local

The chaining wrapper captured stdin with $(cat), which strips the trailing
newline — a chained shell hook built on `while read` then never entered its
loop for the final (usually only) ref line and exited 0, failing OPEN. Use
the printf-x sentinel so the byte-exact input reaches the chained hook, with
tests covering both the pass-through and the short-circuit paths.

* fix(redact-prepush): close the ext-diff, header-lookalike, and ref-parse bypasses

Three ways the pushed diff escaped scanning: (1) a user-level diff.external
or textconv driver replaced the diff with its own output — zero '+' lines,
so the scan saw nothing (now --no-ext-diff --no-textconv); (2) an added
content line whose text begins with "++" renders as "+++…" and the blanket
header skip dropped it (now hunk-aware header detection); (3) a pre-push
ref line that failed to parse was silently skipped, leaving that ref
unscanned (now fails closed with the offending line named).

Minimal reimplementation of the two confirmed bypasses from PR #2498 by
@lubosxyz (the full PR overlaps the chunked-scan work absorbed separately),
plus the unparseable-ref hardening.

* fix(pair-agent): keep the ngrok authtoken out of the transcript and shell argv

The not-authed flow told the user to paste their ngrok authtoken into the
chat so the agent could run `ngrok config add-authtoken` — putting a live
credential in the transcript, tool-call argv, and anything the transcript
syncs to. The user now runs the auth command in their own terminal; the
agent only verifies via `ngrok config check`, and a pasted token triggers a
rotate-and-reauth instruction. A static test pins that no agent-run bash
fence ever contains add-authtoken again.

Fixes #2335.

* fix(update-check): crash emits CHECK_FAILED instead of reading as up-to-date

gstack-update-check signals "up to date" with SILENCE, and it runs under
set -e — so any unguarded mid-script failure exited quietly and was
indistinguishable from a current install. Observed live as a 45-release
silent-staleness incident. An ERR trap (with -E so it propagates into
functions) now emits a CHECK_FAILED sentinel naming the line and status,
and exits 0 so caller `|| true` guards can't eat it. Behavioral tests cover
both the crash and the healthy-silent paths; egress-receipt wiring is
untouched and still pinned by test/egress-receipt-wiring.test.ts.

Fixes #1974. (#2378's HEAD-SHA staleness half was already fixed on main by
the ls-remote + SHA-pinned VERSION resolution — close as already-fixed.)

Diff.diffLines (browse/src/snapshot.ts:571, browse/src/meta-commands.ts:728),

* ci(evals): skip eval jobs deterministically on fork PRs

Fork PRs never receive repository secrets, so every API-calling eval failed
at SDK auth — but only when Docker-cache luck let the jobs start at all,
making fork PRs randomly red or grey. Skip the eval and report jobs
explicitly for fork-origin PRs, keep the image BUILD (validates
Dockerfile.ci changes) without the push a fork token can't perform, and

* fix(extension): deny token/port reads to content-script and foreign senders

background.js answered getPort — port, connected state, AND the browse
server auth token — to any sender that passed the type allowlist,
including content scripts running in web-page context and, behind only
the sender.id check, anything without extension-page provenance. The
getToken sender.tab restriction covered getToken alone, and only after
getPort had already handed out the token.

Single decision point now: extension/sender-auth.js classifies each
message type; the eight privileged types (getPort, setPort, getServerUrl,
getToken, fetchRefs, command, sidebar-command, getTabState) require an
own-extension-page sender (chrome-extension://<own id>/ URL, no
sender.tab, own sender.id). Denied senders get { error: 'unauthorized' }
and nothing else — never the token, never the port. Content-script flows
(elementPicked, pickerCancelled, inspectResult, openSidePanel) are
untouched, and the sidepanel/popup keep the getPort token field their
connect path reads. The policy mirrors the v1.63 server-side model:
AUTH_TOKEN is released only to the pinned extension Origin via
POST /extension-token, so the extension must not re-leak it to contexts
the server would never have trusted.

browse/test/extension-sender-auth.test.ts drives the real background.js
onMessage listener under a chrome stub with four sender shapes (own
extension page, own content script, foreign extension id, missing
sender.url) and pins that denied responses carry no token/port fields,
that a denied setPort never persists, that a denied command never
reaches the network, and that the inspector + tab-state flows keep
working. The helper is loaded via importScripts in the classic service
worker and require()-able from bun tests.

* test(update-check): fixture links gstack-egress-lib.sh — all 38 tests failed on main

v1.63.0.0 made bin/gstack-update-check source bin/gstack-egress-lib.sh
unconditionally, but the test fixture's GSTACK_DIR only linked gstack-config
— every test died at the source line (0/38 pass on pristine main,

earlier file's delayed process.exit before this file ran. Link the lib like

* fix(browse): capture active-tab state before close() — last-tab auto-create raced the close event

closeTab checked `tabId === this.activeTabId` AFTER awaiting page.close(),
but the page 'close' event handler can fire during that await and reassign
activeTabId — losing the race meant the last-tab auto-create never ran,
leaving the manager with zero tabs. Capture wasActive before closing, and
only reassign activeTabId when it no longer points at a live tab.

Part of the test-integrity repairs unmasked by the suite-truncation fix.

* test(browse): delete the orphaned sidebar chat-queue suite; align sidebar-ux/tabs with the PTY-only sidebar

browse/test/sidebar-integration.test.ts tested the /sidebar-command queue
path ripped in v1.14 (34 references to removed endpoints — 11 permanent
failures masked by suite truncation). sidebar-ux.test.ts carried 73 failures
pinning the same dead surface (pickSidebarModel, ANALYSIS_WORDS); the trim

sidebar-tabs gets the two matching expectation updates.

Two static-grep guards pinned superseded source shapes and failed once the

--out disk-write ban (canDispatchOverTunnel takes command AND args), and
lazy PTY spawn routes through the maybeSpawnPty helper since v1.44. The
updated assertions pin the current, stricter shapes (open() never spawns;
the helper is the only spawnClaude caller).

* fix(test): remove all 8 delayed process.exit teardown bombs — the tier-1 gate can finally fail

bun test runs every file in ONE process, so a 500ms setTimeout(process.exit(0))

suite with exit 0 and no summary — only ~16 of 434 files ran, and every
downstream failure was invisible (observed live throughout this wave's
enumeration). Changes, all guarded by fault injection:

- Replace every delayed-exit teardown with a time-boxed close of the file's
  own browser (8 files across browse/ and design/); stub the daemon
  /shutdown timer instead of letting its unconditional process.exit tear
  the runner down.
- test/no-suicide-exit.test.ts: static tripwire — no *.test.ts may schedule
  a delayed process.exit again.
- test/exit-propagation.test.ts + fixtures: fault injection with REAL bun
  output proves the truncation shape (exit 0, no summary) and that
  scripts/test-free-shards.ts now detects it: a shard exiting 0 WITHOUT
  bun's final summary line is treated as FAILED (exit code alone is not
  evidence of completion).
- handoff: the three headed-mode integration tests are darwin-skipped with
  a pointer to the known macOS headed-launch breakage (#2242/#2554); they
  keep running on Linux CI. Un-skip in the browse-daemon wave.
- feedback-roundtrip: repair the handler call sites unmasked by the fix —
  handlers take (command, args, session, bm); passing the manager where a
  session belongs broke all six tests.
- user-slug-fallback: HOME isolation makes endpoint_hash deterministic.

* test: include design/test/ in the free suite and the sharded runner

design/test was absent from both the package.json test globs and TEST_ROOTS
in scripts/test-free-shards.ts — its tests (including one of the teardown
bombs removed in the previous commit) never ran in any CI or local free
run, so design fixes could ship without their unit tests executing.

* fix(make-pdf): reject directories when resolving the browse binary

access(X_OK) is true for directories (they carry the execute/traverse

resolution could pick the ~/.claude/skills/browse alias DIRECTORY as the
browse binary. Every browse call then exited 4 with empty stderr, which
make-pdf surfaced as "Chromium failed to launch" against a perfectly
healthy Chromium (#2156). Guard isExecutable with statSync().isFile()

os.tmpdir() on macOS resolves to /var/folders/..., which fails browse's
safe-dirs validation ([/tmp, cwd]) since the v1.6.0.0 --from-file
tightening. Default PDF output (generate with no -o), the preview HTML,
tmpFile() scratch files, and setup's smoke-test fixture/output all wrote
there, so browse rejected the paths it was asked to read or write.
Export PAYLOAD_TMP_DIR from browseClient (the existing TEMP_DIR
convention: os.tmpdir() on Windows, /tmp elsewhere) and route
orchestrator.ts and setup.ts temp files through it.

* fix(make-pdf): stop URLs swallowing smartypants placeholders

A bare autolinked URL (<a href="X">X</a>) has zero whitespace between
the URL text and its own closing tag. TAG_RE carves that </a> into a
NUL-delimited SMARTPANTS_PRESERVED placeholder BEFORE the URL pass
runs, and URL_RE's \S+ swallowed the adjacent placeholder into the URL
match. The restore pass is single-shot, so the inner placeholder never
restored: raw "SMARTPANTS_PRESERVED_N" text leaked into the rendered
link, the </a> vanished, and link-blue styling bled into the rest of
the document (#2084). Excluding the NUL sentinel (\u0000) from the URL
character class stops the match from crossing into an already-carved
zone.

* fix(make-pdf): no blank first page when content precedes the first H1

Two paths put invisible content ahead of the first H1 and cost users a
blank page 1 (#1904):

- A visually-empty preamble (leading <style> block, HTML comment)
  became its own .chapter. That section took the `.chapter:first-of-type
  { break-before: auto }` exception, so the first real chapter inherited
  `break-before: page` and started on page 2. Non-rendering preambles
  now fold into the first real chapter (markup preserved, no page
  break); real text preambles keep their own chapter.
- Leading YAML frontmatter rendered as a literal paragraph of body text
  on its own first page (marked has no frontmatter awareness). It is
  now stripped before parsing; a `---` thematic break elsewhere is
  untouched.

* fix(browse): allow about:blank so a restarted daemon can initialise

The daemon opens its own first tab on about:blank, so blocking it in
validateNavigationUrl meant a restarted daemon could never recreate the
blank tab it starts from — and `browse newtab about:blank`, which
`make-pdf setup` runs as its Chromium smoke test, failed and surfaced
as "Chromium failed to launch" against a healthy browser.

Allow about:blank ONLY, never the about: scheme: about:blank has no
origin, loads nothing and runs nothing, while about:config and friends
are real surfaces. Exact href match (lower-cased, since the URL parser
normalises the protocol but not the opaque part), so about:blankfoo
stays blocked.

* fix(design): drop gpt-image-2 tool model that 400s under the gpt-4o orchestrator

The Responses API rejects pairing a gpt-4o orchestrator with an
image_generation tool spec'd as model: "gpt-image-2" (400
invalid_request_error), which took every design image call offline —
generate, variants, iterate (both threaded and fresh paths), evolve,
and /design-shotgun (#1771). gpt-image-2 is only valid under a gpt-5
orchestrator; with gpt-4o the tool must omit the model field (defaults
to gpt-image-1).

Remove the model field at all five call sites and add a static-grep
tripwire test (design/test/image-gen-pairing.test.ts) that fails CI if
any design/src module reintroduces the gpt-4o + gpt-image-2 pairing.
Re-enabling gpt-image-2 later requires bumping the orchestrator off
gpt-4o in the same diff, which the tripwire permits.

Pages stage into ~/.gstack/.staging-ingest-*/ inside a repo whose .gitignore

imported nothing, and the ingest still reported "written: N" from the STAGED

layers now: (1) pass --include-gitignored (root cause); (2) if the installed
gbrain predates the flag, retry without it (subcommand --help is generic, so
the attempt is the only probe) with an upgrade pointer; (3) reconcile
gbrain's imported+unchanged accounting against the staged count and REFUSE

* fix(session-update): un-wedge auto-upgrade — autostash over local patches, log the pull's real reason

On a normal install the tracked files ARE locally patched (skill-prefix
name rewrites, gbrain-refresh blocks), so the bare `git pull --ff-only`
refused on every run and auto-upgrade froze forever — observed as 308
consecutive PULL_FAILED entries with the reason discarded by 2>/dev/null.
Pull now runs --autostash (local patches ride over the update and pop back),
stderr is captured into the log so a genuine failure names its cause, an
autostash pop conflict recovers to a clean tree and re-renders the patches
(gstack-patch-names + gbrain-refresh, both idempotent), and a successful
pull re-renders them as a self-heal. Behavioral tests cover the wedge shape
and the reason logging.

bun's 5s default is fine for a file run solo, but the monolithic free suite

30s matches the ceiling the enumeration runs used; the sharded runner

* fix(question-log): parse native AskUserQuestion answers — every native answer logged as __unknown__

Current Claude Code returns AskUserQuestion results as an OBJECT map keyed
by question text ({answers: {question: label}}); the hook only handled the
legacy array shapes, so 86% of live records carried user_choice __unknown__
— and the bin then scored every one as followed_recommendation false,
silently poisoning plan-tune metrics. Adds the object-map extraction (exact
+ whitespace-normalized + single-question pairing, multiSelect joins,
annotations as free_text), strips the (Recommended) suffix from BOTH sides
of the comparison, skips the computation entirely on extraction failure,
and logs unrecognized shapes to hook-errors.log instead of embedding them
in the record.

gstack-slug derived everything from pwd, so a session in a subdirectory got
the subdir's basename as its slug (or an outer monorepo's remote), misfiling
reviews/decisions/learnings under a phantom project — and the per-pwd cache

outermost STRONG marker wins (.git, package.json, pyproject.toml, Cargo.toml,
Gemfile, go.mod, .project.yaml), weak content markers (README, LICENSE) catch
non-code project folders, deploy artifacts are deliberately not markers, and
GSTACK_PROJECT_SLUG remains the escape hatch. The cache self-heals on

* fix(hooks): shared spawn-bin helper — all three AskUserQuestion hooks were inert on Windows

The plan-tune hooks resolved bin scripts via new URL(import.meta.url).pathname

extensionless bash scripts directly (unrunnable without a shell association)
— so question logging, preferences, and the error fallback all silently
no-op'd on Windows, and /plan-tune collected no data. A single spawn-bin.ts
helper now owns bin resolution (fileURLToPath) and win32 bash routing for

raw pattern. This is the one Windows-spawn idiom for hook code.

* fix(windows): grant icacls ACEs by *SID, not unqualified username

An unqualified username handed to icacls is ambiguous: on a machine whose
hostname equals the username (a common Windows setup), it resolves to the
MACHINE account instead of the user. Combined with /inheritance:r, that
leaves ~/.gstack with a single ACE matching nobody — the process that just
"secured" the directory locks itself out, and icacls still reports success.

Both icacls sites in the repo (restrictFilePermissions and
restrictDirectoryPermissions in browse/src/file-permissions.ts — the only
icacls call sites; setup has none) now grant via icacls' literal-SID form
`*<SID>`, resolved once per process from System32\whoami.exe (pinned to
System32 because a bare `whoami` under a bash-flavoured PATH picks up the
MSYS build, which rejects /user). Fallback when the SID can't be resolved
is the domain-qualified `USERDOMAIN\username` name, which is unambiguous
where the bare username was not.

Windows-only regression tests assert the hardened directory stays usable
by the calling process (readdir + write), which is exactly the check that
a not-toThrow assertion sailed past before.

* fix(windows): forward windowsHide through the bun-polyfill spawn shims

windowsHide is the one spawn option where Node's default is the opposite
of Bun's: Node shows the child's console window, Bun.spawn hides it.
The polyfill's spawn and spawnSync shims dropped the option entirely, so
the Node fallback path (dist/bun-polyfill.cjs) silently inverted the
behavior on the one platform the shim exists to serve — every watchdog
respawn of the terminal agent popped a visible bun.exe console window.

Three sites fixed:
- Bun.spawnSync shim: forwards windowsHide with Bun-matching default true
- Bun.spawn shim: same (stdio:'ignore' silences output but does NOT
  suppress the console window on Windows)
- spawnTerminalAgent in terminal-agent-control.ts: explicit
  windowsHide: true, so the Node fallback path behaves like Bun-native

An explicit windowsHide: false is honored at both shims. Three focused
tests pin the default-true, default-true-sync, and explicit-false paths
by intercepting child_process in a subprocess; the test file's require
path now uses forward slashes so it survives interpolation into a JS
string literal on Windows.

Supersedes PRs #2523, #2294 and #2290, which each covered a subset of
these sites.

* fix(watchdog): signal-0 liveness, tick-scaled respawn guard, windowsHide

Three-bug chain behind the Windows terminal-agent leak (console window
strobing every 60s, one orphaned agent per watchdog tick until the box
ran out of committable memory):

1. isProcessAlive shelled out to `tasklist /FI "PID eq <pid>"` on Windows
   with a 3s timeout. A Bun.spawnSync that hits its timeout still RETURNS
   with partial stdout, so the `.includes()` PID match read a LIVE agent
   as dead — killAgentByRecord skipped the kill, the watchdog respawned
   around the survivor, and every orphan slowed the next tasklist enough
   to produce the next false negative. Now: `process.kill(pid, 0)` on
   every platform (Node and Bun both map signal 0 to an OpenProcess
   existence check on Windows), with EPERM counted as alive. No
   subprocess, no timeout, no console window.

2. The respawn circuit-breaker was mathematically unreachable — verified
   in this tree: RESPAWN_GUARD_WINDOW_MS was a fixed 60_000 against a
   60_000ms default tick, and each tick pushes at most one respawn
   timestamp, so three pushes span ~120s and can never coexist inside a
   60s window (eviction is strict `>`, and setInterval drift plus
   per-tick work always ages the prior entry past the boundary). The
   guard could not fire at the default tick rate and a steady
   one-per-tick leak ran unbounded. The window now scales with the tick:
   max(60_000, tick * (RESPAWN_GUARD_MAX + 2)), so "3 crashes in quick
   succession → stop" holds at any tick value.

3. The tasklist probe popped a visible console per tick (no windowsHide).
   Removing the shell-out kills that site; the agent-spawn site itself
   already passes windowsHide: true (landed with the bun-polyfill
   windowsHide commit — PR #2414's terminal-agent-control.ts hunk is
   reconciled there rather than duplicated).

New browse/test/process-liveness-windows.test.ts pins all three: no
subprocess from the probe, a static tripwire against reintroducing
`tasklist` + `PID eq` liveness checks in src/, the spawnTerminalAgent
windowsHide + stdio contract, and the window-derived-from-tick
arithmetic. terminal-agent-watchdog.test.ts test 4 now pins the
window/tick relationship instead of the fixed literal that let this
ship. Also converts `new URL(import.meta.url).pathname` to
`import.meta.path` across the static-grep tests it touches — the
pathname form yields /C:/... on Windows and breaks path.resolve.

* fix(terminal-agent): tie agent lifetime to its owning browse server PID

The terminal agent is intentionally detached so it survives the
short-lived CLI launcher, but its real owner is the persistent browse
server. If that server crashed or was killed before running normal
shutdown, the agent was adopted by PID 1 and lived forever (#2019).

spawnTerminalAgent now requires an ownerPid and exports it to the agent
as BROWSE_OWNER_PID; all three spawn sites pass the server PID (cli.ts
cold-start, cli.ts supervisor respawn, server.ts watchdog). The agent
polls the owner with signal 0 every 15s (GSTACK_TERMINAL_OWNER_WATCHDOG_MS
to tune) on an unref'd timer and, when the owner disappears, exits
through the SAME cleanup path as an intentional SIGTERM shutdown — now
re-entrancy-guarded and also removing the terminal-internal-token file
alongside the port file and agent record.

Runtime test spawns a real agent tied to a throwaway owner process,
kills the owner, and asserts the agent exits and its discovery files
(terminal-agent-pid, terminal-port) are gone.

Reconciled with the watchdog commit's spawnTerminalAgent contract test
(process-liveness-windows.test.ts now passes ownerPid and pins the
BROWSE_OWNER_PID env forwarding).

Closes #2019.

* fix(windows): give the bun-polyfill spawn shim a real `exited` promise

Bun.spawn exposes `proc.exited` as a Promise resolving to the exit code.
The Node fallback shim (dist/bun-polyfill.cjs) returned no such field, so
every `await proc.exited` on the Windows path resolved instantly to
undefined — the Windows cookie picker (cookie-import-browser.ts races
proc.exited at three sites) read stdout before the child produced it and
silent-failed; browser-skill-commands and terminal-agent hit the same
class.

The shim now:
- drains stdout/stderr eagerly into capped in-memory buffers (Node's
  Readables are pull-based; without draining, a child writing past the
  OS pipe buffer blocks in write() and 'exit' never fires), replaying
  them as fresh single-shot Web ReadableStreams so reads work before or
  after awaiting exit;
- caps the buffer at 16 MB (GSTACK_SPAWN_MAX_BUFFER to override), still
  draining past the cap so a runaway child can't wedge or OOM;
- resolves `exited` with Bun-matching codes (exit code, 128+signal, 1 on
  spawn error) after both pipes finish, and resolves on 'error' too —
  Node fires 'error' without 'exit' when the binary is missing, which
  otherwise hangs the await forever.

Six tests pin exit codes, the read-after-exit ordering, spawn-failure
resolution, the buffer cap, and the large-output drain. Adapted to the
current test file (require path goes through the requirePath variable
from the windowsHide commit), and the 1 MB drain test's child now exits
in the write callback — on modern Node a pipe write past the OS buffer
is async and process.exit() straight after write() truncates at ~64 KB
even with a live reader, which fails the test for reasons unrelated to
the shim.

* fix(setup): BROWSE_BIN carries the .exe suffix on Windows

On Windows, `bun build --compile` emits browse.exe, but setup's
BROWSE_BIN pointed at the suffixless path — so the post-build gate
(`[ ! -x "$BROWSE_BIN" ]` → "browse binary missing") could never pass on
Windows even after a fully successful build, while the build step itself
reported success. Closes #2291.

Applied the PR's override after the IS_WINDOWS detection, and also to
the second BROWSE_BIN assignment the PR predates: the direct-Codex-
install migration path re-derives BROWSE_BIN from the migrated dir and
would otherwise drop the suffix again on Windows.

* fix(setup): link lib/ beside bin/ at all five host-install sites

bin/ scripts import shared modules via ../lib (gstack-learnings-log →
lib/jsonl-store.ts is the reported case), so any runtime root that
exposes bin/ without lib/ breaks 13 bin/ commands — learnings-log,
decision-log, telemetry and friends fail with "Cannot find module
.../lib/jsonl-store.ts" on every non-Claude install, silently from the
skills' perspective.

All five host-install sites now carry lib/ next to bin/, each through
the existing _link_or_copy helper (never raw ln — the static invariant
in test/setup-windows-fallback.test.ts enforces this):

- .agents sidecar (create_agents_sidecar asset loop)
- Codex runtime root (create_codex_runtime_root)
- Factory runtime root (create_factory_runtime_root)
- OpenCode runtime root (create_opencode_runtime_root)
- Kiro install block

New test/setup-runtime-lib-command.test.ts executes the real setup shell
for each root in a sandbox (both the symlink branch and the Windows copy
branch of _link_or_copy) and runs gstack-learnings-log end-to-end from
the installed root, asserting the learning lands in
~/.gstack/projects/<slug>/learnings.jsonl — plus a negative control
proving a bin-without-lib root fails exactly the way the bug report did.
gen-skill-docs.test.ts's setup-validation block pins the lib link at
every site. Cross-checked against PRs #2433, #2410 and #2198: all three
cover subsets of these sites; nothing they fix is missing here.

gstack-community-dashboard all source $GSTACK_DIR/supabase/config.sh to
resolve GSTACK_SUPABASE_URL, where GSTACK_DIR is the installed root

project URL on non-Claude installs. Closes #2215.

setup now links supabase/config.sh (file-level on purpose — migrations/
and functions/ are dev-only) via _link_or_copy at all five host-install
sites: the PR's four (Codex, Factory, OpenCode runtime roots + the Kiro
block) plus the .agents sidecar, whose bin/ resolves the same relative
path and which the PR predates covering.

The runtime-root test now asserts supabase/config.sh is present in

* ci(windows): curate the fix-wave regression tests into the windows-latest run

The windows-free-tests curated set is derived (POSIX-fragility regex scan
+ explicit deny list), and two of this wave's Windows regression files
were auto-excluded on false-positive pattern hits:

- browse/test/file-permissions.test.ts tripped the POSIX-mode-bitmask
  pattern, but every `mode & 0o777` assertion is platform-guarded — and
  the file carries the win32-only icacls-by-SID regression tests, which
  can only ever execute on windows-latest.
- browse/test/terminal-agent-owner-watchdog.test.ts tripped the
  spawn(['bun','run',...]) pattern whose reason is the Playwright-bound
  browse server; it actually spawns terminal-agent.ts (fs/path/crypto +
  local helpers only, no Playwright at module scope), and the owner-PID
  orphan leak it pins was reported on Windows (#2019).

Adds a KNOWN_WINDOWS_SAFE force-include list (mirror of
KNOWN_WINDOWS_INCOMPATIBLE, each entry carrying its false-positive
rationale) consulted before the pattern scan, and makes the
owner-watchdog test's throwaway owner process Windows-portable
(process.execPath instead of `sleep`, which a bare runner may not have).

The wave's other new files need no wiring: process-liveness-windows and
the bun-polyfill windowsHide/exited tests pass curation automatically;
setup-runtime-lib-command self-skips on win32 by design (its Windows
branch is exercised by simulating IS_WINDOWS=1 under bash), so
force-including it would add a permanently-skipped file.

* fix(setup): stop piping gen:skill-docs through tail — generator failures were masked

setup piped doc generation through `tail -3`, so a generator crash kept the
pipe's exit 0 and installs completed "successfully" with broken or missing
SKILL.md files. Capture the real exit status at BOTH sites (the main
gen:skill-docs step and the gbrain-detected gen:skill-docs:user regen —
the second drifted in after the PR and its own test caught it), print the
tail for UX, and fail loudly.

* fix(mktemp): move the X-run to the end of every temp-file template (BSD/busybox safe)

BSD mktemp (macOS) does not substitute an X-run that has a suffix after it:
`mktemp "$TMP_ROOT/codex-err-XXXXXX.txt"` creates a LITERAL
codex-err-XXXXXX.txt on the first call (exit 0) and every later call fails
with `mkstemp failed: File exists` — so /codex breaks from the SECOND run on
every Mac, masquerading as a model stall. busybox mktemp (Alpine) rejects the
template on the first run. Fixes #2091, #2370.

Union of both community fixes, compared at the diff level:
- PR #2372: all 11 source sites with a suffix after the X-run — codex
  SKILL.md.tmpl (5), claude SKILL.md.tmpl (3), bin/gstack-developer-profile
  (2, suffix folded into the prefix: .json.tmp.XXXXXX), and the office-hours
  codex pass in scripts/resolvers/review.ts (1).
- PR #2103: the second half of #2091 — bin/gstack-paths now strips the
  trailing slash from TMP_ROOT at the source (macOS $TMPDIR ends in `/`),
  plus runtime tests pinning that normalization.

New repo-wide tripwire in test/regression-issue2091-bsd-mktemp.test.ts:
every .tmpl, every SKILL.md, and every scripts/resolvers/*.ts is swept —
no mktemp template may carry a suffix after the X-run, with a self-test so
the detector can't be quietly blinded. Generated SKILL.md files regenerated
via gen:skill-docs in this commit.

* fix(codex,review,ship): scope codex review with an explicit --base flag, never prompt text

`codex review` takes its scope ONLY from --base/--commit/--uncommitted. The
positional [PROMPT] is mutually exclusive with all three, and a prompt-only
`codex review "<text>"` silently falls back to the uncommitted working-tree
scope (verified on 0.144.1: it runs `git status --short; git diff` and
reviews that) — so the previous prompt-based scoping produced a
confidently-worded review of the WRONG changes and read "no changes" on a
clean tree. Every diff pass now invokes `codex review --base <base>` with no
prompt argument: /codex Step 2A default path, the /review structured pass,
and the /ship adversarial-section pass (all via scripts/resolvers/review.ts).

Custom review instructions keep their own `codex exec` path (the CLI rejects
prompt + scope flag together), with the filesystem boundary preserved there.
Two new Error Handling entries teach the failure shapes: the argv-parse
error, and the "review says no changes on a branch full of changes" symptom.

Tests updated to pin the new invariant instead of banning the fix: the old
assertions required the diff range in prompt text and banned the
`--base <base> -c '...'` substring, which the correct scoped form contains.
Also deletes test/fixtures/golden-ship-claude.md — a 2,565-line orphaned
fixture referenced by zero tests (the live goldens are in
test/fixtures/golden/, compared by test/host-config.test.ts); the factory
golden is refreshed from the regenerated output. Generated SKILL.md files

* fix(review,ship): run the codex diff passes under the timeout wrapper (#1036)

The `_gstack_codex_timeout_wrapper` added in #1056 was wired into
codex/SKILL.md but never into the /review and /ship diff passes, which kept
running under a bare 5-minute Bash gate. An unwrapped stall returns no exit
code and no output, which downstream reads as "Codex reviewed and found
nothing" — a truncated pass silently became a clean bill. Measured on
codex-cli 0.145.0: a pass was killed at 287s of a 300s budget mid-tool-call,
and the same prompt completed in 336s.

Both passes in scripts/resolvers/review.ts (adversarial `codex exec` and the
structured `codex review --base` pass) now re-source gstack-codex-probe and
run under `_gstack_codex_timeout_wrapper 540`, with the Bash tool gate raised
to 600000 ms so the wrapper fires FIRST and a stall surfaces as a diagnosable
exit 124. The timeout guidance now says a timed-out pass is MISSING COVERAGE,
not a clean result, and points at the run's rollout log under
~/.codex/sessions/ for partial output. The stale "timeout doesn't exist on
macOS" claim is gone — the wrapper resolves gtimeout, then timeout, then runs
unwrapped, so it is safe without coreutils.

Static guards in test/codex-hardening.test.ts pin all three sites (resolver,
review/SKILL.md, ship/sections/adversarial.md): both calls wrapped, wrapper
budget strictly under the Bash gate, and no reappearance of the macOS claim
that steered these call sites away from the wrapper in the first place. The
Claude-output path guard in test/gen-skill-docs.test.ts now scrubs
~/.codex/sessions/ (a user-facing Codex CLI path, same class as the
~/.codex/logs/ exemption) before banning Codex host paths. Generated files
regenerated via gen:skill-docs; factory golden refreshed.

* fix(codex): sandbox the review path, fail the gate closed, order timeouts wrapper-first

Closes #2496, #2524, #2477 — three defects in the class "a guard that
reports success while doing nothing", all in codex/SKILL.md.tmpl:

(a) Review sandbox. The default `codex review` path was the only codex call
with no sandbox override, inheriting ~/.codex/config.toml's default — write
access on a trusted project — while Important Rules claimed read-only.
Top-level `codex review` has no -s/--sandbox flag (verified on 0.147.0), so
the invocation now pins `-c 'sandbox_mode="read-only"'`, the same form the
consult-resume path already uses.

(b) Fail-closed verdict gate. The old rule ("no [P1] found → PASS") could
not fail on the default path: native `codex review` output carries no
bracketed tags, and a non-zero exit, expired auth, timeout, or empty result
also contains no [P1] — all read as PASS. The gate is now an ordered,
fail-closed check: non-zero exit → FAIL; empty output → FAIL; [P0]/[P1]
(bracketed or codex's native labels) → FAIL with count; NO severity tags at
all → FAIL requiring a human read; PASS is only reachable through the
explicit tagged-advisory-only branch. [P0] is recognized as blocking, and
the review-log findings count includes it.

(c) Bash gate above the wrapper. Step 2A instructed `timeout: 300000` under
a 330s wrapper, and Challenge's 300s gate sat under a 600s wrapper — the
harness killed the call before the wrapper could emit its diagnosable
exit-124 message. Every Bash gate now sits strictly ABOVE its wrapper:
360000 over the 330s review wrapper, 660000 over the 600s challenge/consult
wrappers, with the ordering rationale stated at each site.

Also from #2477/#2524: a new Error Handling entry for the model-entitlement
400 ("The '<model>' model is not supported...") pointing at the `model =`
pin and `[notice.model_migrations]` in ~/.codex/config.toml and saying
exactly which override to retry with (-m for exec-based modes,
`-c model="..."` for review mode, which rejects -m); the Model & Reasoning
section no longer documents `-m` for `/codex review`.

Static assertions in test/codex-hardening.test.ts pin (a)-(c) across both
the .tmpl and the generated SKILL.md: every scoped review invocation carries
sandbox_mode="read-only" and never -s; the default-PASS sentence is banned
and the fail-closed branches are present; and per-section, every Bash
`timeout: N` is strictly greater than every wrapper budget, with 2A/2B/2C
all required to be inspected. Generated SKILL.md regenerated via
gen:skill-docs in this commit.

* fix(browse): daemon resilience on loaded machines — Bun conn errors, stop/restart flush, startup + git-root budgets

Four load-sensitivity fixes in the daemon lifecycle:

- sendCommand only recognized Node's ECONNREFUSED/ECONNRESET; the compiled
  CLI runs on Bun, which reports 'ConnectionRefused'/'ConnectionClosed'
  ("Unable to connect..."), so daemon crashes leaked the raw error and
  exited 1 instead of entering the busy-check/restart path. Match both.
- stop/restart called shutdown() inline, which exits before the HTTP
  response flushes — the CLI saw a dropped socket (and would now
  crash-retry a fresh daemon just to stop it). Defer shutdown ~100ms so
  the 200 lands first.
- Non-CI POSIX startup budget raised 8s -> 15s (cold Chromium measured
  ~5.7s at load avg 10; load 12+ blew the old budget while the detached
  daemon was still booting).
- getGitRoot's 2s git rev-parse timeout returned null under load (6.3s
  spikes measured), scattering state files across cwds into split-brain
  daemons. Raise to 8s, still bounded.

* fix(slug): cached identity is sticky — heal ONLY the provable subdir-cache bug shape

The walk-up rewrite recomputed the slug on every run and "healed" the cache
toward the fresh value, which broke the #2212 continuity contract: a project
that used gstack before adopting a git remote would be silently renamed to
the remote-derived slug, orphaning everything under ~/.gstack/projects/.
Cached identity now wins, with one precise exception: when the cached value
equals THIS pwd's basename while the walk-up proves pwd is not the project
root, the entry came from the pre-walk-up subdirectory bug (#1125) and is
recomputed. All four slug contracts pass together (repo-mode #2212,
walk-up #1125, sanitize, user-slug).

* fix(claude): stop false-blocking macOS keychain subscription auth in host detection

The /claude skill's auth probe only recognized env-var/API-key auth, so
macOS subscription installs (keychain-backed, where `claude -p` works fine)
were told they had no auth. Detection now uses host invocation.

Fixes #1890.

Contributed by @xing-qnex (PR #2411); PR #2548 by @shawnacalia covered the
keychain case.

* fix(setup): Ubuntu 26.04 Playwright platform detect + silence the codesign false alarm

Two small setup papercuts: the Playwright platform probe now recognizes
Ubuntu 26.04 instead of falling to the generic-Linux path, and macOS
installs stop warning about a codesign "failure" that was actually the
expected unsigned-adhoc path (the real signature check already gates
binary launch).

* fix(skills): land-and-deploy squash readback, next-version paths, embed-flags quoting

Three template one-liners: land-and-deploy reads the squash-merge result
from the merge commit instead of the stale branch tip; review/landing-report
/land-and-deploy templates call bin/gstack-next-version via its installed
path instead of a bare repo-relative one; setup-gbrain quotes
GBRAIN_EMBED_FLAGS so zsh word-splitting stops silently dropping
voyage-code-3 flags. Regenerated output included.

* test(redact-prepush): assemble the fake AWS key at runtime — the literal blocked our own push

The hook's fixtures carried a live-format AKIA literal, and the repo's own
pre-push scanner (hardened in this wave) correctly blocked pushing it. The
placeholder-suppressed docs key would defeat the detection tests, so the
fixtures now concatenate the key at runtime: tests still exercise real
detection, and the pushed diff never contains a scannable credential shape.

* fix(slug): terminate the marker walk-up on dirname's fixed point — hung every bin on Windows

Under git-bash on Windows a mixed-form path walks C:/Users -> C: -> . -> .
forever: dirname's fixed point there is never "/", so the walk-up loop spun
and every bin that evals gstack-slug (learnings-log first among them) hung
until spawn timeout. Caught by windows-free-tests CI on the wave PR. Break
on the fixed point itself with a depth cap for exotic forms; regression
tests drive the extracted function with hostile path shapes under a hard
timeout.

tandClaude Opus 4.8 f55e27097c fix(deps): override basic-ftp to 5.3.1 to clear CVE-2026-39983 + 3 sibling HIGH advisories
basic-ftp reaches the tree only transitively:
  puppeteer-core > @puppeteer/browsers > proxy-agent > pac-proxy-agent > get-uri > basic-ftp

Versions <= 5.3.0 carry four HIGH advisories, all fixed in 5.3.1:
- GHSA-chqc-8p9q-pq6q (CVE-2026-39983) FTP command injection via CRLF
- GHSA-6v7q-wjvx-w8wg incomplete CRLF protection (USER/PASS + MKD bypass)
- GHSA-rpmf-866q-6p89 DoS via unbounded multiline control-response buffering
- GHSA-rp42-5vxx-qpwr DoS via unbounded memory in Client.list()

Pin via a bun `overrides` entry rather than a phantom direct dependency.
Overriding forces every basic-ftp in the tree to 5.3.1, including get-uri's
nested copy; `bun audit` then reports zero basic-ftp advisories (total 37 -> 33,
HIGH 13 -> 9). A direct-dependency bump leaves get-uri/basic-ftp at the
vulnerable version and audit still flags all four.

Garry TanandClaude Fable 5 14fc0866d9 v1.58.0.0 feat: diagram + multi-format document engine (mermaid, excalidraw, single-file HTML, DOCX) (#1990)
* docs(todos): P3 content-hash diagram render cache for make-pdf

Deferred from the diagram-engine eng review (Codex outside-voice D7):
repeat make-pdf runs re-render every fence; cache keyed on fence source +
bundle version once multi-diagram docs make it worth building.

* feat(diagram-render): offline mermaid+excalidraw render bundle for browse

Single self-contained page (dist/diagram-render.html, 9.2MB, committed per
eng-review D2) exposing __renderMermaid / __mermaidToExcalidraw /
__excalidrawToSvg / __rasterize / __probeImage through browse load-html +
js --out. Render contract per D3: securityLevel strict, per-fence ids,
print-css font lock, htmlLabels off (canvas-taint-safe). Deterministic
build (same sha twice); drift test pins dist == BUILD_INFO == package.json
pins and rebuild-reproducibility when toolchain matches. Spike-proven
offline: flowchart + sequence SVG, editable .excalidraw scene, 300dpi PNG.

* feat(diagram-render): __downscaleRaster for print-resolution image normalization

Data-URI rasters re-encode in their own format (JPEG stays JPEG at q0.9 —
PNG-encoding photos bloats them) at an explicit target pixel width. Used by
make-pdf's pre-pass for the 300dpi content-box ceiling (eng-review D4).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(make-pdf): diagram pre-pass — mermaid/excalidraw fences render as vector SVG; local images inline as data URIs

```mermaid / ```excalidraw fences extract to placeholder tokens, render in
one diagram-render bundle tab per run (reset contract: bundle page reloads
after any render error), and substitute back as accessible <figure> blocks
with the raw source preserved in a comment. Render failures produce a loud
red diagnostic block, never silent raw code. render=false keeps a fence as
code; title="..." becomes the aria-label and caption.

Local images now actually render: page.setContent loads at about:blank
(tab-session.ts:194), so relative paths silently 404'd before. The pre-pass
resolves them against the markdown's directory, inlines as data URIs, probes
intrinsic dimensions from the bytes (pure-TS PNG/JPEG/GIF/WebP/SVG sniffing),
and downscales rasters wider than 2x the content box at 300dpi. Remote URLs
warn (offline posture, --allow-network exempts); missing files get a visible
placeholder; --strict hard-fails both for CI pipelines.

* test(make-pdf): diagram pre-pass unit suite + e2e render gates

34 unit tests (fence extraction incl. nested/tilde/unclosed/render=false,
info-string parsing, slot substitution, diagnostic/figure escaping + SVG
script strip, byte-level dimension probing across 5 formats, content-box
math, image inlining incl. strict/remote/missing/data-URI paths). E2E gate
proves through the compiled binary: both fences render as vector text
(id-collision check), raw mermaid ships only via render=false, broken fence
yields the diagnostic block, and the relative fixture image rasterizes to
colored pixels (CRITICAL regression for the about:blank image fix).
--strict exits non-zero on a missing image.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(make-pdf): width directives + conservative auto-landscape via CSS named pages

`![a](x.png){width=full|<pct>|<dim>}` and `{page=landscape|portrait}`
suffixes translate to data-gstack-* attrs in render() (before the sanitizer,
which keeps data- attributes; unrecognized brace groups stay visible text).
Default width rule needs no code: intrinsic CSS-px capped at the content box,
never upscaled — figure img max-width owns it.

Auto-landscape promotes a block to `@page wide { size: <pagesize> landscape }`
only when aspect >= 1.8 AND intrinsic width > 2.5x the content box (~1600px on
letter) AND diagram provenance (rendered fences) or a whole-word alt token
(diagram|architecture|flowchart|chart|graph) for plain images. {page=...}
forces or vetoes; fence info strings accept page=... too. preferCSSPageSize
is passed to Chromium only when a promotion exists, so every other document
prints exactly as before. False negatives are cheap; false positives feel
broken (eng-review P4, Codex challenge accepted).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(make-pdf): width-policy unit suite + landscape e2e gate with negative fixtures

24 unit tests weighted toward the false-positive guards: wide screenshot
without an alt hint stays portrait, sub-threshold and tall images stay
portrait, deterministic 1560/1561px boundary, whole-word alt matching
('photographic' must not match 'graph'), page=portrait veto beats every
heuristic, diagnostic blocks never promote. E2E gate asserts pdfinfo
per-page boxes through the compiled binary: exactly 3 of 5 fixture blocks
get landscape pages (alt-hinted image, directive-forced image, wide sequence
diagram) while the unhinted screenshot and the veto'd diagram stay portrait —
plus the --toc combo proving TOC and named-page landscape coexist.

* feat(make-pdf): --to html|docx output formats

--to html writes the assembled self-contained document directly (no print
round-trip): inline vector diagrams, data-URI images, zero network
references, plus an @media screen layer for browser reading. --to docx is
the content-fidelity export (eng-review P8): html-to-docx@1.8.0 (exact pin;
pure JS, bun-compile-verified) maps headings/tables/code/lists; diagrams and
SVG images rasterize at 300dpi of the content-box width via the render tab;
diagnostic figures convert to plain p/pre so the converter can't silently
drop an error. --format keeps its page-size-alias meaning; --to is the
output format, and the CLI says so when confused.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(make-pdf): format gate — html no-network-refs + docx zip content checks

HTML: zero src/href network refs, no script/link tags, inline SVG diagrams,
data-URI images, screen layer, diagnostic survives. DOCX: valid OOXML zip
(document.xml + Content_Types), >=2 PNG media (diagram raster + fixture
image), headings + render=false source + diagnostic text in document.xml,
no leaked mermaid source from rendered fences. Plus --to validation UX.

* feat(diagram): /diagram skill — English in, editable diagram triplet out

New skill: agent authors mermaid from the user's description and renders the
triplet through the offline diagram-render bundle in the browse daemon —
.mmd source (the single source of truth), editable .excalidraw (opens at
excalidraw.com, round-trips back through re-render), and SVG + PNG. Flowcharts
convert to fully editable scenes; other mermaid types render with an explicit
upstream-converter limitation note. Never ships an unrendered source file;
offline is the contract (no CDN fallback). Inventory rows in AGENTS.md +
docs/skills.md; generated SKILL.md + llms.txt via gen:skill-docs.

* test(diagram): paid E2E pair — gate triplet contract + periodic authoring judge

diagram-triplet (gate, deterministic functional): a fresh claude -p agent

.mmd, excalidraw scene with >3 elements, SVG markup, PNG magic bytes.
Verified live: pass, $0.17, 58s. diagram-authoring-quality (periodic,
LLM-judged): faithfulness/labels/size rubric with a diagnostic-path cap,
floor 6/10. Verified live: pass at exactly 6 with substantive critique.
Touchfiles select both on diagram/** and lib/diagram-render/** changes;
tier split per E2E_TIERS rules (eng-review D5).

* feat(make-pdf): typography scale-up, zero image truncation, landscape vertical centering

Dogfooding round on the repo README surfaced four output-quality bugs:

- Type was too small everywhere: body 11→12pt, h1 22→26pt, h2 15→18pt,
  cover title 32→56pt with poster spacing, cover meta 10→13pt, TOC 11→12pt
  with tighter leading, code 9.5→10.5pt, tables 10→11pt.
- Zero image truncation, ever: the max-width cap was figure-scoped, but
  markdown images render as <p><img> — a 1850px GitHub screenshot ran off
  the page edge. Global img { max-width: 100%; height: auto; } cap.
- hyphens: auto put real 'dif-\nferent' breaks into the PDF text layer the
  moment 12pt made lines wrap (combined-gate caught it). Clean copy-paste
  is the product contract; left-aligned rag doesn't need hyphenation →
  hyphens: manual.
- Promoted landscape blocks now vertically center. CSS flex/min-height
  centering fragments into phantom empty landscape pages in Chromium
  (bisected: min-height at ANY value; 3 promotions printed 5 pages), so
  image-policy computes an inline margin-top from each block's known
  aspect ratio against the landscape content box instead — fragmentation
  handles margins fine. .page-wide also drops its explicit break-before/
  after (the page-name change already breaks on both sides).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(make-pdf): pin zero-truncation invariant, typography floor, centering math

Global img cap pinned as a regex invariant (the figure-scoped-cap regression
class); typography floor (12pt body, 56pt cover, 12pt TOC); .page-wide must
NOT carry min-height/flex (the phantom-landscape-page regression class);
centering margin math verified both ways (2400×1000 image → 1.38in,
2050×600 viewBox diagram → 1.93in, page-filling directive block → no margin).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs: diagram + multi-format documentation across README, make-pdf skill, and how-to guide

README gains /make-pdf (Publisher) and /diagram (Diagram Maker) rows in the
sprint table. make-pdf's skill doc — the agent-facing contract — gains Core
patterns for mermaid/excalidraw fences (title/render=false/page= options),
the image policy ({width=}/{page=} directives, zero-truncation, conservative
auto-landscape), --to html|docx, and --strict, plus the --to vs --format
disambiguation in Common flags. New docs/howto-diagrams-and-formats.md is
the user-facing walkthrough: fences, directives, formats, /diagram triplet,
the mermaid racetrack trick, troubleshooting.

* test(make-pdf): fill ship-audit coverage gaps — downscale, reset contract, excalidraw fence, WebP

Ship coverage audit found 9 gaps (85%); this fills the 2 HIGH + 3 MEDIUM and
most LOW. diagram-gate fixture gains a 4200px incompressible photo (the only
live coverage of __downscaleRaster AND the 64KB chunked jsViaBuffer eval
transport — asserted via the downscale stderr warning), an ```excalidraw
scene fence rendered through exportToSvg (vector labels + caption in
pdftotext, no leaked scene JSON), and the broken fence MOVED BETWEEN the two
mermaid fences so the second diagram rendering proves the D6.2 reset
contract end-to-end. New coverage-gaps.test.ts (16 tests): mock-tab reset
contract (exactly one reload, post-failure fence renders), excalidraw
fail-fast diagnostic without a bundle call, rasterize error fallbacks
(figure/tag kept, never silent), WebP VP8/VP8L/VP8X byte parsers,
landscapeContentBox a4/asymmetric margins, bare-token slot fallback,
resolveBundlePath env override + error shape, screenCss media scoping.

* fix(make-pdf): pre-landing review wave — fence fidelity, injection hardening, Windows paths, transport rework

Review army (6 specialists + red team) findings, all fixed:

- Indented fences replay byte-for-byte and indented diagram fences are NOT
  extracted (red-team conf-9: the pre-pass reconstructed fences at column 0,
  splitting any list containing fenced code — every ordinary document).
- String.replace $-pattern injection killed at every seam: substituteSlots,
  mergeStyle, img/src rewrites all use function replacements (a diagram label
  containing $' duplicated the document tail).
- Big-expression transport reworked: browse `eval <file>` (one spawn, any
  size, Windows-safe) replaces the 64KB chunked window-buffer eval — fixes
  the per-chunk spawn cost, the char-vs-byte argv units, AND the Windows
  32,767-char command-line ceiling in one move.
- Staged-bundle trust: content verified by hash even when the file exists,
  and the rename-failure path re-hashes the survivor (sticky-bit /tmp EPERM
  would otherwise ride a pre-planted file past the check).
- Windows drive-letter img srcs (C:/x.png) reach the local-path branch
  instead of being swallowed as unknown URL schemes.
- DOCX rasterize-failure now embeds the decoded source as visible text —
  returning the figure made diagrams vanish silently (converter drops svg).
- Fence source preserved as base64 data-gstack-source attribute (the comment
  encoding corrupted every '-->' arrow); decodeFigureSource() round-trips.
- inlineLocalImages memoizes per path; file:// uses fileURLToPath; preview
  prints a divergence note for fences/local images; --to docx strips the
  watermark div and warns about print-only flags; TOC links resolve in
  html/docx (heading ids assigned); waitForExpression sleeps instead of
  busy-spinning; escapeHtml/svg-dims deduped to single definitions;
  typography stragglers (blockquote 12pt, footnotes 10pt, 42em screen
  measure); bundle BUILD_INFO gains srcSha256 for no-node_modules drift
  detection; MAX_TARGET_PX shared guard.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* ci: make-pdf gate covers the diagram-render bundle; bundle pinned to LF

make-pdf-gate.yml paths gain lib/diagram-render/** and the drift test (a
bundle-only PR previously skipped every render gate AND no CI lane ran the
drift check at all). .gitattributes pins dist html/json to LF so Windows
autocrlf can't break the hash-pinned bundle.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test(make-pdf)+feat(diagram): review-wave test pins + skill transport hardening

Tests: indented-fence byte-for-byte replay + no-extraction-in-lists,
drive-letter local-path routing, $-pattern slot immunity, base64 source
round-trip ('A --> B' exact), existing-style merge preservation, DOCX
rasterize-failure surfaces source, srcSha256 + font-stack drift guards,
landscape veto asserted as some-portrait/no-landscape (layout-order-proof),
judge rubric cap lowered to 5 so it actually fails, vacuous error-shape test
removed honestly, tmpdir cleanup.

/diagram skill: base64 transport (template literals corrupted backticks/${
in sources), content-addressed staging with hash verification, and --tab-id
pinned on every browse call so a concurrent /qa session can't be clobbered.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* feat(make-pdf): out-of-tree image reads warn; --strict makes them fatal (D8.1)

Local CLI semantics stay (absolute paths and ../ still inline, like pandoc),
but never silently: an agent PDF-ing untrusted markdown can't quietly embed a
file from outside the input directory into a shareable document without a
visible warning, and --strict pipelines hard-fail. Two unit tests. Also:
TODOS.md gains the deferred e2e-harness dedup entry (D8.2).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix: pre-existing test failure in skill-e2e-bws operational-learning

Root cause was the fixture, not model behavior: gstack-learnings-log gained
an import of lib/jsonl-store.ts in the v1.57.5.0 injection-sanitization wave,
but the test copies only bin/ scripts into its sandbox — the inline bun
import failed and the script exited 1 before writing, on every run, on main
too (reproduced at a5833c41). Fixture now stages lib/jsonl-store.ts beside
bin/; verified deterministically (script exits 0, learning written) and via
the paid test (1 pass).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(make-pdf): adversarial-review wave — offline posture enforced, symlink-aware confinement, bounded reads

Codex adversarial + structured review findings:

- Remote images are now BLOCKED with a visible placeholder instead of
  warn-and-keep — leaving the tag meant Chromium fetched the URL at print
  time anyway, so the offline posture was a lie (tracking pixels and
  internal-URL probes ran without --allow-network).
- The out-of-tree read check compares REAL paths: a symlink inside the input
  dir pointing at ~/.ssh/... passed the string-prefix check, including under
  --strict. Ordered after the existence check (realpath of a missing file
  false-positives on macOS /var → /private/var).
- Image reads are bounded BEFORE reading: statSync first, non-regular files
  (fifo/device/dir) and >64MB files degrade to placeholders instead of
  hanging or exhausting memory; malformed percent-encoding (foo%zz.png)
  degrades to missing-image instead of crashing decodeURIComponent.
- browse shell-outs get a 120s timeout — a wedged daemon or hostile mermaid
  source fails the run instead of hanging it.
- TOC entries link to the heading's ACTUAL id (pre-id'd raw-HTML headings
  previously got dead #toc-N links); per-side margins compose into the CSS
  @page shorthand so a landscape promotion flipping preferCSSPageSize no
  longer silently reverts --margin-left/right to defaults (Codex P2).
- The image memo is a typed object — literal NUL-byte separators had made
  diagram-prepass.ts register as binary to text tooling.

Codex structured review GATE: PASS (no P1).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs: sync make-pdf image-policy docs with final shipped behavior (v1.58.0.0)

The docs wave (87594420) predated the final review-wave commits, so two
docs drifted from shipped behavior:

- make-pdf/SKILL.md.tmpl + generated SKILL.md: remote images are BLOCKED
  with a visible placeholder (not warned-and-kept); out-of-tree reads
  (including via symlink) warn and --strict makes them fatal; --strict
  also covers oversized (>64MB) and non-regular files; troubleshooting
  entry now names the actual "[remote image blocked]" symptom.
- docs/howto-diagrams-and-formats.md: same corrections in the image
  section, CI section, and troubleshooting.
- README.md: docs/howto-diagrams-and-formats.md added to the Docs table
  (was unreachable from any entry-point doc).

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* docs: apply Codex doc-review findings for v1.58.0.0

Cross-model doc review (Codex, read-only) checked the v1.58.0.0 docs
against the shipped code. Fixes:

- howto + make-pdf SKILL: diagram source is preserved base64 in a
  data-gstack-source attribute, not an HTML comment (-- in mermaid
  arrows would corrupt a comment); fences must start at column 0;
  fence options example gains page=portrait; --to html "zero network
  refs" qualified (--allow-network deliberately keeps remote tags).
- /diagram description, README + docs/skills.md rows: the hand-drawn
  aesthetic belongs to the .excalidraw artifact; rendered SVG/PNG use
  mermaid's clean neutral theme (lib/diagram-render entry.ts pins
  theme: "neutral").
- CHANGELOG v1.58.0.0 wording: --strict coverage lists all five fatal
  classes (missing/remote/out-of-tree/oversized/non-regular); fences
  are vector SVG in pdf+html, 300dpi PNG in docx; hand-drawn claim
  scoped to the .excalidraw file.
- lib/diagram-render/README: Page API table gains __downscaleRaster.

Garry TanandClaude Opus 4.7 443bde054c v1.28.0.0 feat: browse --headed/--proxy/--navigate + gstack/llms.txt + webdriver-only stealth (#1363)
* feat(browse): SOCKS5 bridge with auth + cred redaction helper

Adds browse/src/socks-bridge.ts: a 127.0.0.1-only SOCKS5 listener that
accepts unauthenticated connections from Chromium and relays them through
an authenticated upstream proxy. Chromium does not prompt for SOCKS5 auth
at launch, so this bridge is the workaround for using auth-required
residential SOCKS5 upstreams.

- startSocksBridge({ upstream, port: 0 }) → ephemeral 127.0.0.1 listener
- testUpstream({ upstream, retries: 3, backoffMs: 500, budgetMs: 5000 })
  pre-flight that connects to a known endpoint (default 1.1.1.1:443)
- Stream-error policy: kill affected client + upstream sockets on any
  error mid-stream; no transport retries (a transport-layer retry can
  corrupt browser traffic)

Adds browse/src/proxy-redact.ts: single source of truth for redacting
credentials in any logged proxy URL or upstream config. Every code path
that prints proxy config goes through this helper.

Adds the socks npm dep (~30KB) and 16 tests covering: 127.0.0.1-only
bind, byte-for-byte round trip through the bridge, auth rejection,
mid-stream upstream drop kills client conn, listener teardown,
testUpstream success + retry-exhaust paths, redaction of every
credential shape.

* feat(browse): --proxy and --headed flags wire bridge into daemon

Adds the global --proxy <url> and --headed flags to the browse CLI.
Resolves cred policy and routes the daemon launch through the SOCKS5
bridge (or pass-through for HTTP/HTTPS) before chromium.launch().

CLI (cli.ts):
- extractGlobalFlags() strips --proxy/--headed from argv, parses URL via
  Node URL class, validates D9 cred-mixing (env BROWSE_PROXY_USER/PASS
  + URL creds → exit 1 with hint), composes canonical proxy URL with
  resolved creds, computes a stable configHash for daemon-mismatch
- ensureServer() now reads existing daemon's configHash from state file
  and refuses (exit 1 with disconnect hint) if --proxy/--headed mismatch
  the existing daemon. No silent restart that would drop tab state.
- All proxy-related stderr lines go through redactProxyUrl

proxy-config.ts (new):
- parseProxyConfig() — URL parser + D9 cred-mixing detector + scheme allowlist
- computeConfigHash() — stable hash of (proxy URL minus creds + headed flag)
- toUpstreamConfig() — map ParsedProxyConfig → socks-bridge.UpstreamConfig

Server (server.ts):
- Reads BROWSE_PROXY_URL at startup; for SOCKS5+auth, runs testUpstream
  pre-flight (5s budget, 3 retries, 500ms backoff) and exits 1 on failure
  with redacted error
- Spawns startSocksBridge() on 127.0.0.1:<ephemeral> and points
  Chromium at it via socks5://127.0.0.1:<port>
- HTTP/HTTPS or unauth SOCKS5 → pass-through to chromium.launch
  proxy.server (with username/password if present)
- State file gains optional configHash for daemon-mismatch check
- Bridge tears down via process.on('exit')

Browser manager (browser-manager.ts):
- New setProxyConfig({ server, username, password }) called by server.ts
  before launch
- chromium.launch() and both launchPersistentContext sites pass the
  proxy config through when set

Tests: 22 new across proxy-config (parse + cred-mixing + hash stability)
and extractGlobalFlags (flag stripping + cred-mixing rejection + cred
rotation hash stability + redaction).

* feat(browse): Xvfb auto-spawn with PID + start-time validation

Adds browse/src/xvfb.ts: a Linux-only Xvfb auto-spawn module for
running headed Chromium in containers without DISPLAY. The module
walks a display range to pick a free one (never hardcodes :99) and
validates orphan PIDs by BOTH /proc/<pid>/cmdline matching 'Xvfb' AND
start-time matching the recorded value before sending any signal.
Defends against PID reuse — refuses to kill anything that doesn't
match both checks.

- shouldSpawnXvfb(env, platform) — pure decision: skip on macOS/Windows,
  on Linux skip when DISPLAY or WAYLAND_DISPLAY is set (codex F2)
- pickFreeDisplay(99..120) — probes via xdpyinfo
- spawnXvfb(display) — returns { pid, startTime, display } handle
- isOurXvfb(pid, startTime) — both-checks validator
- cleanupXvfb(state) — best-effort, validates ownership before SIGTERM

Wired into server.ts startup: when shouldSpawnXvfb says yes, picks a
free display, spawns Xvfb, sets DISPLAY for chromium.launchHeaded, and
records xvfbPid/xvfbStartTime/xvfbDisplay in the state file. Cleanup
runs on process.on('exit'). The CLI's disconnect path also runs
cleanupXvfb() in the force-cleanup branch when the server is dead.

Disconnect now applies to any non-default daemon (headed mode OR
configHash-tagged daemon — i.e. one started with --proxy/--headed),
not just headed mode.

Adds xvfb + x11-utils to .github/docker/Dockerfile.ci so CI exercises
the Linux container --headed path on every run. Without it the most
common production path would go untested.

Tests: 17 new across decision logic, PID validation defenses
(cmdline mismatch, start-time mismatch), no-op safety on bad inputs,
and a Linux+Xvfb-installed gate for the spawn → validate → cleanup
round trip. Tests skip on macOS/Windows automatically.

* feat(browse): webdriver-mask stealth + Chromium-through-bridge e2e

D7 (codex narrowing): mask navigator.webdriver only via addInitScript.
The wintermute approach (fake plugins=[1..5], fake languages=['en-US',
'en'], stub window.chrome) is intentionally NOT applied — modern
fingerprinters check consistency between plugins.length, languages,
userAgent, and platform, and synthesizing fixed values can flag MORE
bot-like, not less. The honest minimum is webdriver, which Chromium
exposes as a known automation tell.

Adds browse/src/stealth.ts: single source of truth for the stealth
init script and launch args. Both browser-manager.launch() (headless)
and launchHeaded() (persistent context with extension) call
applyStealth(context) and pass STEALTH_LAUNCH_ARGS into chromium.launch.

The pre-existing launchHeaded stealth that did fake plugins/languages
is removed for the same reason. The cdc_/__webdriver runtime cleanup
and Permissions API patch are kept — they remove automation-injected
artifacts, not synthesize fake natural-browser values.

Adds bridge-chromium-e2e.test.ts (codex F3): the test that proves the
FEATURE works. Real Chromium with proxy.server = 'socks5://127.0.0.1:
<bridgePort>' navigates to a local HTTP fixture; the auth upstream's
connect counter and the HTTP fixture's hit counter both increment,
proving traffic actually traversed bridge → auth-upstream → destination.
Without this test, we could ship a working byte-relay and a broken
Chromium integration and never know.

Adds bridge-port-restart.test.ts (codex F1, reframed): old test
assumed two daemons coexist, which contradicts D2 single-daemon model.
Reframed as restart-then-restart, asserting fresh ephemeral ports
(never the hardcoded 1090) on each spin-up.

Adds stealth-webdriver.test.ts: navigator.webdriver=false in both
fresh contexts and persistent contexts; navigator.plugins/languages
are NOT replaced with the wintermute fake list (D7 verification).

* feat(gstack): generate llms.txt — single-file capability index for AI agents

Adds scripts/gen-llms-txt.ts: produces gstack/llms.txt at repo root,
indexing every skill (47), every browse command (75), and design
commands when the design CLI is present. Per the llmstxt.org
convention, agents can read one file to learn what gstack offers
instead of crawling 47 SKILL.md files.

Sources:
- skill SKILL.md.tmpl frontmatter (name + description block scalar)
- browse/src/commands.ts COMMAND_DESCRIPTIONS (sorted by category)
- design/src/commands.ts COMMAND_DESCRIPTIONS if present (best-effort)

Wired into scripts/gen-skill-docs.ts as a post-step so it regenerates
on every `bun run gen:skill-docs` (the same script that re-emits all
SKILL.md files). Failures are non-fatal warnings, not build breaks —
the generator never blocks SKILL.md regen.

Strict mode (--strict, also used by tests) throws when a skill is
missing name or description in its frontmatter, catching missing
metadata before it ships.

Tests: shape (top-level sections, sort order, single-line summary
discipline), every-skill-and-command-appears, strict-mode rejection of
incomplete frontmatter, and freshness check that the committed
gstack/llms.txt matches what the generator produces now.

* feat(browse): --navigate flag on download for browser-triggered files

Adds the --navigate strategy from community PR #1355 (originally from
@garrytan-agents). When set, download navigates to the URL with
waitUntil:'commit' and captures the resulting browser download via
page.waitForEvent('download'), then saves via download.saveAs().
Handles URLs that trigger files via Content-Disposition headers,
multi-hop CDN redirects requiring browser cookies, or anti-bot CDN
chains where page.request.fetch() can't follow the auth/redirect
chain.

Defaults still use the existing direct-fetch strategy. --navigate is
opt-in.

Goes through the same validateNavigationUrl SSRF gate as goto, so
download --navigate cannot reach IPv4 metadata endpoints (AWS IMDSv1,
GCP/Azure equivalents) or arbitrary internal hosts.

Inferred content type from suggested filename for common extensions
(epub, pdf, zip, gz, mp3/mp4, jpg/jpeg/png, txt, html, json) — falls
back to application/octet-stream. Same 200MB cap as Strategy 1.

Frames the use case generically (anti-bot CDN, Content-Disposition,
redirect chains) rather than naming any specific site, per project
voice rules.

* docs: v1.28.0.0 — browse SKILL section + VERSION + CHANGELOG

VERSION 1.27.1.0 → 1.28.0.0 (MINOR — substantial new capability:
five new flags/features, ~600 LOC added, new socks dep, multiple
new modules).

browse/SKILL.md.tmpl: new "Headed Mode + Proxy + Anti-Bot Sites"
section between User Handoff and Snapshot Flags. Documents
--headed (auto-Xvfb on Linux), --proxy (with embedded SOCKS5
bridge for auth), download --navigate, the cred-mixing policy,
daemon-discipline (refuse-on-mismatch), the narrowed
webdriver-only stealth, container support caveats, and the
fail-fast/no-retry failure modes.

CHANGELOG entry follows the release-summary format from CLAUDE.md:
two-line headline, lead paragraph, "The numbers that matter"
table tied to specific test files that prove each capability,
"What this means for AI agents" closing tied to a real workflow
shift, then itemized Added/Changed/Fixed/For-contributors
sections.

Browse SKILL.md regenerated via bun run gen:skill-docs.
gstack/llms.txt regenerated automatically from the same pipeline.

* test(browse): integration coverage for daemon mismatch + proxy fail-fast

Adds two integration tests that exercise the full process boundary,
not just the module-level wiring.

daemon-mismatch-refuse.test.ts (D2):
- Stubs a healthy state file with a fake configHash and a fake /health
  HTTP server, runs the actual cli.ts binary with a mismatching
  --proxy, asserts exit 1 + 'different config' / 'browse disconnect'
  hint in stderr.
- Same shape with the plain-daemon-meets---headed case.
- Positive case: matching configHash → CLI does NOT emit the mismatch
  hint (regardless of whether the actual command succeeds).

server-proxy-fail-fast.test.ts:
- Starts the rejecting SOCKS5 upstream, spawns server.ts with
  BROWSE_PROXY_URL pointing at it, BROWSE_HEADLESS_SKIP=1 to skip
  Chromium launch.
- Asserts exit 1, 'FAIL upstream' in stderr (testUpstream pre-flight
  ran), no raw credential leakage in any output (redaction works on
  the failure path), and exit within 30s upper bound.

Both tests use the existing spawn-bun-cli pattern from
commands.test.ts so they run on the same CI infrastructure as the
rest of the bun test suite.

* fix(gen-skill-docs): keep module sync so test require() still works

Two regressions caught by the full test suite after the v1.28.0.0
landing pass:

1) package.json version mismatch — VERSION was bumped to 1.28.0.0
   but package.json still pinned to 1.27.1.0.
   test/gen-skill-docs.test.ts asserts they match.

2) Top-level await in scripts/gen-llms-txt.ts (CLI entry block) and
   scripts/gen-skill-docs.ts (post-step) made gen-skill-docs an
   async module. test/gen-skill-docs.test.ts uses require() to pull
   extractVoiceTriggers/processVoiceTriggers from gen-skill-docs,
   which Bun rejects on async modules with:
     "TypeError: require() async module ... unsupported.
      use 'await import()' instead."

Fix: wrap the await blocks in void IIFEs so the modules remain sync
from a require() perspective.

After fix: all 379 gen-skill-docs tests pass, all 77 new feature
tests pass (3 skipped on macOS — Linux+Xvfb gates).

* fix(browse): apply codex adversarial findings on the new lifecycle

Codex outside-voice review caught five real production-failure modes in
the v1.28.0.0 proxy/headed lifecycle. Fixed:

1) `browse disconnect` skip-graceful for proxy-only daemons
   (browse/src/cli.ts). The graceful /command POST went out with stray
   `domains,` shorthand and (even fixed) the server's disconnect handler
   only tears down headed mode — proxy-only daemons returned 200 "Not
   in headed mode" while leaving the bridge running. Now disconnect
   short-circuits to force-cleanup for non-headed daemons, which kicks
   process.on('exit') in server.ts to close the bridge + Xvfb.

2) sendCommand crash retry preserves --proxy / --headed
   (browse/src/cli.ts). The ECONNRESET retry path called startServer()
   with no extraEnv, silently dropping the proxied flags. A daemon that
   died mid-command would silently restart in default direct/headless
   mode and bypass the SOCKS bridge. Now reapplies BROWSE_PROXY_URL,
   BROWSE_HEADED, and BROWSE_CONFIG_HASH from the resolved global flags.

3) `connect` honors --proxy (browse/src/cli.ts). The headed-mode
   `connect` command built its own serverEnv that didn't include
   BROWSE_PROXY_URL, so `browse --proxy <url> connect` launched headed
   Chromium without the proxy. Now threads proxyUrl + configHash into
   the connect serverEnv.

4) SOCKS5 bridge handles fragmented TCP frames
   (browse/src/socks-bridge.ts). Previously used once('data') and
   parsed each chunk as a complete SOCKS5 frame — TCP doesn't preserve
   message boundaries and split greetings/CONNECT requests caused
   intermittent handshake failures. Replaced with a single state
   machine that buffers chunks and uses size predicates on the SOCKS5
   header to know when a complete frame has arrived. Pauses the client
   socket during upstream connect and replays any remainder bytes
   into the upstream on success.

5) Xvfb cleanup-then-state-delete ordering
   (browse/src/server.ts). emergencyCleanup() previously deleted the
   state file BEFORE any Xvfb cleanup could read it, orphaning Xvfb
   on uncaughtException / unhandledRejection. Now reads the state
   file first, calls cleanupXvfb() (which validates cmdline +
   start-time before kill), then deletes the state file.

Adds a regression test for #4: writes the SOCKS5 greeting + CONNECT
one byte at a time with 5ms ticks, asserts a clean round trip after
the fragmented handshake.

Codex's sixth finding (bridge advertises NO_AUTH on 127.0.0.1, so any
co-located process can use the authenticated upstream) is documented
as a known limitation — gstack's threat model assumes single-user
hosts. Adding bridge-side auth is a separate change.

* docs: update BROWSER.md + TODOS.md for v1.28.0.0

BROWSER.md picks up a "Headed mode + proxy + browser-native downloads
(v1.28.0.0)" subsection inside Real-browser mode plus the new source-map
entries (socks-bridge.ts, proxy-config.ts, proxy-redact.ts, xvfb.ts,
stealth.ts). TODOS.md anti-bot-stealth item updated to reflect the v1.28
narrowing — the "fake plugins" line is no longer accurate.

* fix(ci): include bun.lock in image build for deterministic install

CI evals all failed on PR #1363 with:
  error: Could not resolve: "smart-buffer". Maybe you need to "bun install"?
  error: Could not resolve: "ip-address". Maybe you need to "bun install"?
  at /opt/node_modules_cache/socks/build/client/socksclient.js:15

The cached node_modules layer in the pre-baked Docker image had
`socks` (the new dep) but was missing its transitive deps (smart-buffer,
ip-address). The image build copied only package.json into the build
context — without bun.lock, `bun install` resolved a different tree
than local `bun install` did, dropping required transitive deps.

Reproduces locally as 229 packages (correct) when bun.lock is present
or absent. Why CI diverged isn't fully understood — possibly Docker
layer cache reuse across image rebuilds — but the deterministic fix is
to include the lockfile in the image build context and use
`--frozen-lockfile`, matching what every CI doc recommends.

Changes:
- .github/docker/Dockerfile.ci: COPY bun.lock alongside package.json,
  switch `bun install` → `bun install --frozen-lockfile` so any future
  lockfile drift fails loudly during image build instead of producing
  a partially-installed cache that breaks downstream eval jobs.
- .github/workflows/evals.yml: include bun.lock in the image-tag hash
  so adding/removing a dep invalidates the image, AND copy bun.lock
  into the docker context alongside package.json.
- .github/workflows/evals-periodic.yml: same updates.
- .github/workflows/ci-image.yml: rebuild trigger now fires on bun.lock
  changes too; build context includes bun.lock.

Image hash changes → fresh image gets built on next CI run → install
matches the lockfile exactly → no missing transitive deps.

* fix(ci): use hardlink copy instead of symlink for node_modules cache

After the bun.lock fix landed, the eval matrix STILL failed identically:
  Could not resolve: "smart-buffer" / "ip-address"
  at /opt/node_modules_cache/socks/build/client/socksclient.js

But the hash-tagged image actually contains smart-buffer + ip-address +
socks all flat in /opt/node_modules_cache (verified by pulling and
inspecting the image). 207 packages, all present.

Root cause: the workflow used `ln -s /opt/node_modules_cache node_modules`
to restore deps. Bun build (and Node module resolution generally) walks
a file's realpath to find sibling deps. From the symlinked
/workspace/node_modules/socks/build/client/socksclient.js, realpath
resolves to /opt/node_modules_cache/socks/build/client/socksclient.js,
and walking up to find a node_modules/smart-buffer dir fails — there's
no `node_modules` segment in the realpath.

Switch `ln -s` → `cp -al` (hardlink-copy). Each file in the cache becomes
a hardlink at /workspace/node_modules/<pkg>, sharing inodes (no data
copy). Realpath of /workspace/node_modules/socks/.../socksclient.js
stays inside /workspace/node_modules, so sibling deps resolve correctly.

Speed is comparable to symlink — `cp -al` on ~200 packages on tmpfs is
sub-second. Same caching story preserved.

Both evals.yml and evals-periodic.yml updated.

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

* fix(ci): cp -r instead of cp -al — /opt and /workspace are different filesystems

The hardlink-copy fix landed and immediately broke with:
  cp: cannot create hard link 'node_modules/<file>' to
      '/opt/node_modules_cache/<file>': Invalid cross-device link

GitHub Actions runners mount the workspace volume at /workspace
(overlay-fs layered onto the runner image), and /opt is the runner
image's own filesystem. Cross-filesystem hardlinks aren't supported.

Switch `cp -al` → `cp -r`. Cost: ~5s for ~200 packages of small JS
files vs ~0s for the broken symlink. Still cheaper than the ~15s
`bun install` fallback. Realpath of /workspace/node_modules/<pkg>/...
stays inside /workspace, so bun build's sibling-dep resolution works.

Both evals.yml and evals-periodic.yml updated.

Garry TanandClaude Opus 4.7 ed1e4be2f6 feat: gstack browser sidebar = interactive Claude Code REPL with live tab awareness (v1.14.0.0) (#1216)
* build: vendor xterm@5 for the Terminal sidebar tab

Adds xterm@5 + xterm-addon-fit as devDependencies and a `vendor:xterm`
build step that copies the assets into `extension/lib/` at build time.
The vendored files are .gitignored so the npm version stays the source
of truth. xterm@5 is eval-free, so no MV3 CSP changes needed.

No runtime callers yet — this just stages the assets.

* feat(server): add pty-session-cookie module for the Terminal tab

Mirrors `sse-session-cookie.ts` exactly. Mints short-lived 30-min HttpOnly
cookies for authenticating the Terminal-tab WebSocket upgrade against
the terminal-agent. Same TTL, same opportunistic-pruning shape, same
"scoped tokens never valid as root" invariant. Two registries instead of
one because the cookie names are different (`gstack_sse` vs `gstack_pty`)
and the token spaces must not overlap.

No callers yet — wired up in the next commit.

* feat(server): add terminal-agent.ts (PTY for the Terminal sidebar tab)

Translates phoenix gbrowser's Go PTY (cmd/gbd/terminal.go) into a Bun
non-compiled process. Lives separately from `sidebar-agent.ts` so a
WS-framing or PTY-cleanup bug can't take down the chat path (codex
outside-voice review caught the coupling risk).

Architecture:
- Bun.serve on 127.0.0.1:0 (never tunneled).
- POST /internal/grant accepts cookie tokens from the parent server over
  loopback, authenticated with a per-boot internal token.
- GET /ws upgrades require BOTH (a) Origin: chrome-extension://<id> and
  (b) the gstack_pty cookie minted by /pty-session. Either gate alone is
  insufficient (CSWSH defense + auth defense).
- Lazy spawn: claude PTY is not started until the WS receives its first
  data frame. Idle sidebar opens cost nothing.
- Bun PTY API: `terminal: { rows, cols, data(t, chunk) }` — verified at
  impl time on Bun 1.3.10. proc.terminal.write() for input,
  proc.terminal.resize() for resize, proc.kill() + 3s SIGKILL fallback
  on close.
- process.on('uncaughtException'|'unhandledRejection') handlers so a
  framing bug logs but doesn't kill the listener loop.

Test-only `BROWSE_TERMINAL_BINARY` env override lets the integration
tests spawn /bin/bash instead of requiring claude on every CI runner.

Not yet spawned by anything — wired in the next commit.

* feat(server): wire /pty-session route + spawn terminal-agent

Server-side glue connecting the Terminal sidebar tab to the new
terminal-agent process.

server.ts:
- New POST /pty-session route. Validates AUTH_TOKEN, mints a gstack_pty
  HttpOnly cookie via pty-session-cookie.ts, posts the cookie value to
  the agent's loopback /internal/grant. Returns the terminalPort + Set-Cookie
  to the extension.
- /health response gains `terminalPort` (just the port number — never a
  shell token). Tokens flow via the cookie path, never /health, because
  /health already surfaces AUTH_TOKEN to localhost callers in headed mode
  (that's a separate v1.1+ TODO).
- /pty-session and /terminal/* are deliberately NOT added to TUNNEL_PATHS,
  so the dual-listener tunnel surface 404s by default-deny.
- Shutdown path now also pkills terminal-agent and unlinks its state files
  (terminal-port + terminal-internal-token) so a reconnect doesn't try to
  hit a dead port.

cli.ts:
- After spawning sidebar-agent.ts, also spawn terminal-agent.ts. Same
  pattern: pkill old instances, Bun.spawn(['bun', 'run', script]) with
  BROWSE_STATE_FILE + BROWSE_SERVER_PORT env. Non-fatal if the spawn
  fails — chat still works without the terminal agent.

* feat(extension): Terminal as default sidebar tab

Adds a primary tab bar (Terminal | Chat) above the existing tab-content
panes. Terminal is the default-active tab; clicking Chat returns to the
existing claude -p one-shot flow which is preserved verbatim.

manifest.json: adds ws://127.0.0.1:*/ to host_permissions so MV3 doesn't
block the WebSocket upgrade.

sidepanel.html: new primary-tabs nav, new #tab-terminal pane with a
"Press any key to start Claude Code" bootstrap card, claude-not-found
install card, xterm mount point, and "session ended" restart UI. Loads
xterm.js + xterm-addon-fit + sidepanel-terminal.js. tab-chat is no
longer the .active default.

sidepanel.js: new activePrimaryPaneId() helper that reads which primary
tab is selected. Debug-close paths now route back to whichever primary
pane is active (was hardcoded to tab-chat). Primary-tab click handler
toggles .active classes and aria-selected. window.gstackServerPort and
window.gstackAuthToken exposed so sidepanel-terminal.js can build the
/pty-session POST and the WS URL.

sidepanel-terminal.js (new): xterm.js lifecycle. Lazy-spawn — first
keystroke fires POST /pty-session, then opens
ws://127.0.0.1:<terminalPort>/ws. Origin + cookie are set automatically
by the browser. Resize observer sends {type:"resize"} text frames.
ResizeObserver, tab-switch hooks, restart button, install-card retry.
On WS close shows "Session ended, click to restart" — no auto-reconnect
(codex outside-voice flagged that as session-burning).

sidepanel.css: primary-tabs bar + Terminal pane styling (full-height
xterm container, install card, ended state).

* test: terminal-agent + cookie module + sidebar default-tab regression

Three new test files:

terminal-agent.test.ts (16 tests): pty-session-cookie mint/validate/
revoke, Set-Cookie shape (HttpOnly + SameSite=Strict + Path=/, NO Secure
since 127.0.0.1 over HTTP), source-level guards that /pty-session and
/terminal/* are NOT in TUNNEL_PATHS, /health does NOT surface ptyToken
or gstack_pty, terminal-agent binds 127.0.0.1, /ws upgrade enforces
chrome-extension:// Origin AND gstack_pty cookie, lazy-spawn invariant
(spawnClaude is called from message handler, not upgrade), uncaughtException/
unhandledRejection handlers exist, SIGINT-then-SIGKILL cleanup.

terminal-agent-integration.test.ts (7 tests): spawns the agent as a real
subprocess in a tmp state dir. Verifies /internal/grant accepts/rejects
the loopback token, /ws gates (no Origin → 403, bad Origin → 403, no
cookie → 401), real WebSocket round-trip with /bin/bash via the
BROWSE_TERMINAL_BINARY override (write 'echo hello-pty-world\n', read it
back), and resize message acceptance.

sidebar-tabs.test.ts (13 tests): structural regression suite locking the
load-bearing invariants of the default-tab change — Terminal is .active,
Chat is not, xterm assets are loaded, debug-close path no longer hardcodes
tab-chat (uses activePrimaryPaneId), primary-tab click handler exists,
chat surface is not accidentally deleted, terminal JS does NOT auto-
reconnect on close, manifest declares ws:// + http:// localhost host
permissions, no unsafe-eval.

Plan called for Playwright + extension regression; the codebase doesn't
ship Playwright extension launcher infra, so we follow the existing
extension-test pattern (source-level structural assertions). Same
load-bearing intent — locks the invariants before they regress.

* docs: Terminal flow + threat model + v1.1 follow-ups

SIDEBAR_MESSAGE_FLOW.md: new "Terminal flow" section. Documents the WS
upgrade path (/pty-session cookie mint → /ws Origin + cookie gate →
lazy claude spawn), the dual-token model (AUTH_TOKEN for /pty-session,
gstack_pty cookie for /ws, INTERNAL_TOKEN for server↔agent loopback),
and the threat-model boundary — the Terminal tab bypasses the entire
prompt-injection security stack on purpose; user keystrokes are the
trust source. That trust assumption is load-bearing on three transport
guarantees: local-only listener, Origin gate, cookie auth. Drop any
one of those three and the tab becomes unsafe.

CLAUDE.md: extends the "Sidebar architecture" note to include
terminal-agent.ts in the read-this-first list. Adds a "Terminal tab is
its own process" note so a future contributor doesn't bolt PTY logic
onto sidebar-agent.ts.

TODOS.md: three new follow-ups under a new "Sidebar Terminal" section:
  - v1.1: PTY session survives sidebar reload (Issue 1C deferred).
  - v1.1+: audit /health AUTH_TOKEN distribution (codex finding #2 —
    a pre-existing soft leak that cc-pty-import sidesteps but doesn't
    fix).
  - v1.1+: apply terminal-agent's process.on exception handlers to
    sidebar-agent.ts (codex finding #4 — chat path has no fatal
    handlers).

* feat(extension): Terminal-only sidebar — auth fix, UX polish, chat rip

The chat queue path is gone. The Chrome side panel is now just an
interactive claude PTY in xterm.js. Activity / Refs / Inspector still
exist behind the `debug` toggle in the footer.

Three threads of change, all from dogfood iteration on top of
cc-pty-import:

1. fix(server): cross-port WS auth via Sec-WebSocket-Protocol
   - Browsers can't set Authorization on a WebSocket upgrade. We had
     been minting an HttpOnly gstack_pty cookie via /pty-session, but
     SameSite=Strict cookies don't survive the cross-port jump from
     server.ts:34567 to the agent's random port from a chrome-extension
     origin. The WS opened then immediately closed → "Session ended."
   - /pty-session now also returns ptySessionToken in the JSON body.
   - Extension calls `new WebSocket(url, [`gstack-pty.<token>`])`.
     Browser sends Sec-WebSocket-Protocol on the upgrade.
   - Agent reads the protocol header, validates against validTokens,
     and MUST echo the protocol back (Chromium closes the connection
     immediately if a server doesn't pick one of the offered protocols).
   - Cookie path is kept as a fallback for non-browser callers (curl,
     integration tests).
   - New integration test exercises the full protocol-auth round-trip
     via raw fetch+Upgrade so a future regression of this exact class
     fails in CI.

2. fix(extension): UX polish on the Terminal pane
   - Eager auto-connect when the sidebar opens — no "Press any key to
     start" friction every reload.
   - Always-visible ↻ Restart button in the terminal toolbar (not
     gated on the ENDED state) so the user can force a fresh claude
     mid-session.
   - MutationObserver on #tab-terminal's class attribute drives a
     fitAddon.fit() + term.refresh() when the pane becomes visible
     again — xterm doesn't auto-redraw after display:none → display:flex.

3. feat(extension): rip the chat tab + sidebar-agent.ts
   - Sidebar is Terminal-only. No more Terminal | Chat primary nav.
   - sidebar-agent.ts deleted. /sidebar-command, /sidebar-chat,
     /sidebar-agent/event, /sidebar-tabs* and friends all deleted.
   - The pickSidebarModel router (sonnet vs opus) is gone — the live
     PTY uses whatever model the user's `claude` CLI is configured with.
   - Quick-actions (🧹 Cleanup / 📸 Screenshot / 🍪 Cookies) survive
     in the Terminal toolbar. Cleanup now injects its prompt into the
     live PTY via window.gstackInjectToTerminal — no more
     /sidebar-command POST. The Inspector "Send to Code" action uses
     the same injection path.
   - clear-chat button removed from the footer.
   - sidepanel.js shed ~900 lines of chat polling, optimistic UI,
     stop-agent, etc.

Net diff: -3.4k lines across 16 files. CLAUDE.md, TODOS.md, and
docs/designs/SIDEBAR_MESSAGE_FLOW.md rewritten to match. The sidebar
regression test (browse/test/sidebar-tabs.test.ts) is rewritten as 27
structural assertions locking the new layout — Terminal sole pane,
no chat input, quick-actions in toolbar, eager-connect, MutationObserver
repaint, restart helper.

* feat: live tab awareness for the Terminal pane

claude in the PTY now has continuous tab-aware context. Three pieces:

1. Live state files. background.js listens to chrome.tabs.onActivated /
   onCreated / onRemoved / onUpdated (throttled to URL/title/status==
   complete so loading spinners don't spam) and pushes a snapshot. The
   sidepanel relays it as a custom event; sidepanel-terminal.js sends
   {type:"tabState"} text frames over the live PTY WebSocket.
   terminal-agent.ts writes:
     <stateDir>/tabs.json          all open tabs (id, url, title, active,
                                   pinned, audible, windowId)
     <stateDir>/active-tab.json    current active tab (skips chrome:// and
                                   chrome-extension:// internal pages)
   Atomic write via tmp + rename so claude never reads a half-written
   document. A fresh snapshot is pushed on WS open so the files exist by
   the time claude finishes booting.

2. New $B tab-each <command> [args...] meta-command. Fans out a single
   command across every open tab, returns
   {command, args, total, results: [{tabId, url, title, status, output}]}.
   Skips chrome:// pages; restores the originally active tab in a finally
   block (so a mid-batch error doesn't leave the user looking at a
   different tab); uses bringToFront: false so the OS window doesn't
   jump on every fanout. Scope-checks the inner command BEFORE the loop.

3. --append-system-prompt hint at spawn time. Claude is told about both
   the state files and the $B tab-each command up front, so it doesn't
   have to discover the surface by trial. Passed via the --append-system-
   prompt CLI flag, NOT as a leading PTY write — the hint stays out of
   the visible transcript.

Tests:
- browse/test/tab-each.test.ts (new) — registration + source-level
  invariants (scope check before loop, finally-restore, bringToFront:false,
  chrome:// skip) + behavior tests with a mock BrowserManager that verify
  iteration order, JSON shape, error handling, and active-tab restore.
- browse/test/terminal-agent.test.ts — three new assertions for
  tabState handler shape, atomic-write pattern, and the
  --append-system-prompt wiring at spawn.

Verified live: opened 5 tabs, ran $B tab-each url against the live
server, got per-tab JSON results back, original active tab restored
without OS focus stealing.

* chore: drop sidebar-agent test refs after chat rip

Five test files / describe blocks targeted the deleted chat path:
- browse/test/security-e2e-fullstack.test.ts (full-stack chat-pipeline E2E
  with mock claude — whole file gone)
- browse/test/security-review-fullstack.test.ts (review-flow E2E with real
  classifier — whole file gone)
- browse/test/security-review-sidepanel-e2e.test.ts (Playwright E2E for
  the security event banner that was ripped from sidepanel.html)
- browse/test/security-audit-r2.test.ts (5 describe blocks: agent queue
  permissions, isValidQueueEntry stateFile traversal, loadSession session-ID
  validation, switchChatTab DocumentFragment, pollChat reentrancy guard,
  /sidebar-tabs URL sanitization, sidebar-agent SIGTERM→SIGKILL escalation,
  AGENT_SRC top-level read converted to graceful fallback)
- browse/test/security-adversarial-fixes.test.ts (canary stream-chunk split
  detection on detectCanaryLeak; one tool-output test on sidebar-agent)
- test/skill-validation.test.ts (sidebar agent #584 describe block)

These all assumed sidebar-agent.ts existed and tested chat-queue plumbing,
chat-tab DOM round-trip, chat-polling reentrancy, or per-message classifier
canary detection. With the live PTY there is no chat queue, no chat tab,
no LLM stream to canary-scan, and no per-message subprocess. The Terminal
pane's invariants are covered by the new browse/test/sidebar-tabs.test.ts
(27 structural assertions), browse/test/terminal-agent.test.ts, and
browse/test/terminal-agent-integration.test.ts.

bun test → exit 0, 0 failures.

* chore: bump version and changelog (v1.14.0.0)

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

* fix(extension): xterm fills the full Terminal panel height

The Terminal pane only rendered into the top portion of the panel — most
of the panel below the prompt was an empty black gap. Three layered
issues, all about xterm.js measuring dimensions during a layout state
that wasn't ready yet:

1. order-of-operations in connect(): ensureXterm() ran BEFORE
   setState(LIVE), so term.open() measured els.mount while it was still
   display:none. xterm caches a 0-size viewport synchronously inside
   open() and never auto-recovers when the container goes visible.
   Flipped: setState(LIVE) → ensureXterm.

2. first fit() ran synchronously before the browser had applied the
   .active class transition. Wrapped in requestAnimationFrame so layout
   has settled before fit() reads clientHeight.

3. CSS flex-overflow trap: .terminal-mount has flex:1 inside the
   flex-column #tab-terminal, but .tab-content's `overflow-y: auto` and
   the lack of `min-height: 0` on .terminal-mount meant the item
   couldn't shrink below content size. flex:1 then refused to expand
   into available space and xterm rendered into whatever its initial
   2x2 measurement happened to be.

Fixes:
- extension/sidepanel-terminal.js: reorder + RAF fit
- extension/sidepanel.css: .terminal-mount gets `flex: 1 1 0` +
  `min-height: 0` + `position: relative`. #tab-terminal overrides
  .tab-content's `overflow-y: auto` to `overflow: hidden` (xterm has
  its own viewport scroll; the parent shouldn't compete) and explicitly
  re-declares `display: flex; flex-direction: column` for #tab-terminal.active.

bun test browse/test/sidebar-tabs.test.ts → 27/27 pass.
Manually verified: side panel opens → Terminal fills full panel height,
xterm scrollback works, debug-tab toggle still repaints correctly.

Garry TanandClaude Opus 4.7 e3d7f49c74 feat(v1.10.1.0): overlay efficacy harness + Opus 4.7 fanout nudge removal (#1166)
* refactor: export readOverlay from model-overlay resolver

Needed by the overlay-efficacy eval harness to resolve INHERIT directives
without going through generateModelOverlay's full TemplateContext.

* chore: add @anthropic-ai/claude-agent-sdk@0.2.117 dep

Pinned exact for SDK event-shape stability. Used by the overlay-efficacy
harness to drive the model through a closer-to-real Claude Code harness
than `claude -p`.

* feat(preflight): sanity check for agent-sdk + overlay resolver

Verifies: SDK loads, claude-opus-4-7 is a live API model, SDKMessage
event shape matches assumptions, readOverlay resolves INHERIT directives
and includes expected content. Run with `bun run scripts/preflight-agent-sdk.ts`.

PREFLIGHT OK on first run, $0.013 API spend.

* feat(eval): parametric overlay-efficacy harness (runner + fixtures)

`test/helpers/agent-sdk-runner.ts` wraps @anthropic-ai/claude-agent-sdk
with explicit `AgentSdkResult` types, process-level API concurrency
semaphore, and 3-shape 429 retry (thrown error, result-message error,
mid-stream SDKRateLimitEvent). Pins the local claude binary via
`pathToClaudeCodeExecutable`.

`test/fixtures/overlay-nudges.ts` holds the typed registry. Two
fixtures for the first measurement: `opus-4-7-fanout-toy` (3-file read)
and `opus-4-7-fanout-realistic` (mixed-tool audit). Strict validator
rejects duplicate ids, non-integer trials, unsafe overlay paths, non-safe
id chars, and missing overlay files at module load.

Adding a future overlay nudge eval = one fixture entry.

* test(eval): unit tests for agent-sdk-runner (36 tests, free tier)

Stub `queryProvider` feeds hand-crafted SDKMessage streams. Covers:
happy-path shape, all 3 rate-limit shapes + retry, workspace reset on
retry, persistent 429 -> `RateLimitExhaustedError`, non-429 propagation,
process-level concurrency cap, options propagation, artifact path
uniqueness, cost/turn mapping, and every validator rejection case.

* test(eval): paid periodic overlay-efficacy harness

`test/skill-e2e-overlay-harness.test.ts` iterates OVERLAY_FIXTURES,
runs two arms per fixture (overlay-ON, overlay-OFF) at N=10 trials with
bounded concurrency. Arms use SDK preset `claude_code` so both include
the real Claude Code system prompt; overlay-ON appends the resolved
overlay text. Saves per-trial raw event streams to
`~/.gstack/projects/<slug>/transcripts/` for forensic recovery.

Gated on `EVALS=1 && EVALS_TIER=periodic`. ~$3/run (40 trials).

* test: register overlay harness in touchfiles (both maps)

Entries for `overlay-harness-opus-4-7-fanout-toy` and
`opus-4-7-fanout-realistic` in E2E_TOUCHFILES (deps: model-overlays/,
fixtures file, runner, resolver) and E2E_TIERS (`periodic`). Passes
`test/touchfiles.test.ts` completeness check.

* fix(opus-4.7): remove "Fan out explicitly" overlay nudge

Measured counterproductive under the new SDK harness. Baseline Opus 4.7
emits first-turn parallel tool_use blocks 70% of the time on a 3-file
read prompt. With the custom nudge: 10%. With Anthropic's own canonical
`<use_parallel_tool_calls>` block from their parallel-tool-use docs:
0%. Both overlays suppress fanout; neither improves it.

On realistic multi-tool prompts (audit a project: read files + glob +
summarize), Opus 4.7 never fans out in first turn regardless of overlay.
Zero of 20 trials. Not a prompt problem.

Keeping the other three nudges (effort-match, batch questions, literal
interpretation) pending their own measurement. Harness is ready for
follow-up fixtures — add one entry to
`test/fixtures/overlay-nudges.ts` to measure any overlay bullet.

Cost of investigation: ~$7 total across 3 eval runs.

* chore: bump version and changelog (v1.6.5.0)

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

* feat(eval): extend OverlayFixture with allowedTools, maxTurns, direction

Per-fixture tool allowlist unblocks measuring nudges that need Edit/Write
(e.g. literal-interpretation 'fix the failing tests' needs write access).
Per-fixture maxTurns lets harder prompts run longer without changing the
default. `direction` is cosmetic metadata for test output labeling.

Also adds reusable predicates and metrics:
- lowerIsBetter20Pct / higherIsBetter20Pct — 20% lift threshold vs baseline
- bashToolCallCount — count of Bash tool_use across the session
- turnsToCompletion — SDK-reported num_turns at result
- uniqueFilesEdited — Edit/Write/MultiEdit file_path set size

test/skill-e2e-overlay-harness.test.ts now threads fixture.allowedTools
and fixture.maxTurns through runArm.

* test(eval): 3 more overlay fixtures to measure remaining Claude nudges

Measures three overlay bullets that haven't been tested yet:

- claude-dedicated-tools-vs-bash — claude.md says 'prefer Read/Edit/Write/
  Glob/Grep over cat/sed/find/grep'. Fixture prompts 'list every TypeScript
  file under src/ and tell me what each exports' and counts Bash tool_use
  across the session. Overlay-ON should drop it by >=20%.
- opus-4-7-effort-match-trivial — opus-4-7.md says 'simple file reads
  don't need deep reasoning.' Fixture uses a trivial one-file prompt
  (config.json lookup) and measures turns_used. Overlay-ON should be
  <=80% of baseline turns.
- opus-4-7-literal-interpretation — opus-4-7.md says 'fix ALL failing
  tests, not just the obvious one.' Fixture seeds three failing test
  files with deliberately distinct failure modes and counts unique files
  edited. Overlay-ON should touch >=20% more files.

Adding a fourth fixture for any remaining overlay nudge is a single entry.
The harness is now proven on: fanout (deleted after measurement), dedicated
tools, effort-match, and literal-interpretation.

* fix(eval): handle SDK max-turns throw gracefully

Some @anthropic-ai/claude-agent-sdk versions throw from the query
generator when maxTurns is reached, instead of emitting a result
message with subtype='error_max_turns'. The runner treated that as
a non-retryable error and killed the whole periodic run on the first
fixture that exceeded its turn cap.

Added isMaxTurnsError() detector and a catch branch that synthesizes
an AgentSdkResult from events captured before the throw, with
exitReason='error_max_turns' and costUsd=0 (unknown from the thrown
path). The metric function still runs against whatever assistant
turns were collected, so the trial produces a usable number.

Hoisted events/assistantTurns/toolCalls/assistantTextParts and the
timing counters out of the inner try so the catch branch can read
them. No behavior change on the success path or on rate-limit retry
paths.

* test(eval): bump maxTurns to 15 for claude-dedicated-tools-vs-bash

The prompt 'list every TypeScript file under src/ and tell me what
each exports' needs 1 turn for Glob + ~5 for Reads + 1 for summary.
Default maxTurns=5 was not enough; prior run threw from the SDK on
this fixture and tanked the whole periodic eval.

Bumping to 15 gives headroom. The runner now also handles max-turns
gracefully even if a future fixture underestimates, so this is belt
and suspenders.

* test(eval): Sonnet 4.6 variants of the 5 Opus-4.7 fixtures

Same overlays, same prompts, same metrics, `model: 'claude-sonnet-4-6'`.
Tests whether the overlays behave differently on a weaker Claude model
where baseline behavior is shakier. Sonnet trials cost ~3-4x less than
Opus so these 5 add ~$4.50 to a full run.

Measurement result from the first paired run (100 trials total,
~$14.55):

- **Sonnet + effort-match shows real overlay benefit.** With the overlay
  on, Sonnet takes 2.5 turns on a trivial `What's the version in
  config.json?` prompt. Without, it takes exactly 3.0 turns in all 10
  trials. ~17% reduction, below the 20% pass threshold but the signal
  is clean: overlay-ON distribution [2,2,2,2,2,3,3,3,3,3] vs overlay-OFF
  [3,3,3,3,3,3,3,3,3,3].
- All other Sonnet dimensions flat (fanout, dedicated-tools, literal
  interpretation). Same as Opus on those axes.
- Opus effort-match remains flat (2.60 vs 2.50, +4% slower with overlay).

Implication: model-stratified. The overlay stack helps Sonnet on some
axes where it does nothing on Opus. Wholesale removal would hurt Sonnet.
Per-nudge per-model measurement is the right move going forward.

* chore: bump version to 1.10.1.0

Updates VERSION, package.json, CHANGELOG header, and TODOS completion
marker from 1.6.5.0 to 1.10.1.0.

Garry TanandClaude Opus 4.7 97584f9a59 feat(security): ML prompt injection defense for sidebar (v1.4.0.0) (#1089)
* chore(deps): add @huggingface/transformers for prompt injection classifier

Dependency needed for the ML prompt injection defense layer coming in the
follow-up commits. @huggingface/transformers will host the TestSavantAI
BERT-small classifier that scans tool outputs for indirect prompt injection.

Note: this dep only runs in non-compiled bun contexts (sidebar-agent.ts).
The compiled browse binary cannot load it because transformers.js v4 requires
onnxruntime-node (native module, fails to dlopen from bun compile's temp
extract dir). See docs/designs/ML_PROMPT_INJECTION_KILLER.md for the full
architectural decision.

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

* feat(security): add security.ts foundation for prompt injection defense

Establishes the module structure for the L5 canary and L6 verdict aggregation
layers. Pure-string operations only — safe to import from the compiled browse
binary.

Includes:
  * THRESHOLDS constants (BLOCK 0.85 / WARN 0.60 / LOG_ONLY 0.40), calibrated
    against BrowseSafe-Bench smoke + developer content benign corpus.
  * combineVerdict() implementing the ensemble rule: BLOCK only when the ML
    content classifier AND the transcript classifier both score >= WARN.
    Single-layer high confidence degrades to WARN to prevent any one
    classifier's false-positives from killing sessions (Stack Overflow
    instruction-writing-style FPs at 0.99 on TestSavantAI alone).
  * generateCanary / injectCanary / checkCanaryInStructure — session-scoped
    secret token, recursively scans tool arguments, URLs, file writes, and
    nested objects per the plan's all-channel coverage decision.
  * logAttempt with 10MB rotation (keeps 5 generations). Salted SHA-256 hash,
    per-device salt at ~/.gstack/security/device-salt (0600).
  * Cross-process session state at ~/.gstack/security/session-state.json
    (atomic temp+rename). Required because server.ts (compiled) and
    sidebar-agent.ts (non-compiled) are separate processes.
  * getStatus() for shield icon rendering via /health.

ML classifier code will live in a separate module (security-classifier.ts)
loaded only by sidebar-agent.ts — compiled browse binary cannot load the
native ONNX runtime.

Plan: ~/.gstack/projects/garrytan-gstack/ceo-plans/2026-04-19-prompt-injection-guard.md

* feat(security): wire canary injection into sidebar spawnClaude

Every sidebar message now gets a fresh CANARY-XXXXXXXXXXXX token embedded
in the system prompt with an instruction for Claude to never output it on
any channel. The token flows through the queue entry so sidebar-agent.ts
can check every outbound operation for leaks.

If Claude echoes the canary into any outbound channel (text stream, tool
arguments, URLs, file write paths), the sidebar-agent terminates the
session and the user sees the approved canary leak banner.

This operation is pure string manipulation — safe in the compiled browse
binary. The actual output-stream check (which also has to be safe in
compiled contexts) lives in sidebar-agent.ts (next commit).

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

* test(security): make sidebar-agent destructure check regex-tolerant

The test asserted the exact string `const { prompt, args, stateFile, cwd, tabId } = queueEntry`
which breaks whenever security or other extensions add fields (canary, pageUrl,
etc.). Switch to a regex that requires the core fields in order but tolerates
additional fields in between. Preserves the test's intent (args come from the
queue entry, not rebuilt) while allowing the destructure to grow.

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

* feat(security): canary leak check across all outbound channels

The sidebar-agent now scans every Claude stream event for the session's
canary token before relaying any data to the sidepanel. Channels covered
(per CEO review cross-model tension #2):

  * Assistant text blocks
  * Assistant text_delta streaming
  * tool_use arguments (recursively, via checkCanaryInStructure — catches
    URLs, commands, file paths nested at any depth)
  * tool_use content_block_start
  * tool_input_delta partial JSON
  * Final result payload

If the canary leaks on any channel, onCanaryLeaked() fires once per session:

  1. logAttempt() writes the event to ~/.gstack/security/attempts.jsonl
     with the canary's salted hash (never the payload content).
  2. sends a `security_event` to the sidepanel so it can render the approved
     canary-leak banner (variant A mockup — ceo-plan 2026-04-19).
  3. sends an `agent_error` for backward-compat with existing error surfaces.
  4. SIGTERM's the claude subprocess (SIGKILL after 2s if still alive).

The leaked content itself is never relayed to the sidepanel — the event is
dropped at the boundary. Canary detection is pure-string substring match,
so this all runs safely in the sidebar-agent (non-compiled bun) context.

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

* feat(security): add security-classifier.ts with TestSavantAI + Haiku

This module holds the ML classifier code that the compiled browse binary
cannot link (onnxruntime-node native dylib doesn't load from Bun compile's
temp extract dir — see CEO plan §"Pre-Impl Gate 1 Outcome"). It's imported
ONLY by sidebar-agent.ts, which runs as a non-compiled bun script.

Two layers:

L4 testsavant_content — TestSavantAI BERT-small ONNX classifier. First call
triggers a one-time 112MB model download to ~/.gstack/models/testsavant-small/
(files staged into the onnx/ layout transformers.js v4 expects). Classifies
page snapshots and tool outputs for indirect prompt injection + jailbreak
attempts. On benign-corpus dry-run: Wikipedia/HN/Reddit/tech-blog all score
SAFE 0.98+, attack text scores INJECTION 0.99+, Stack Overflow
instruction-writing now scores SAFE 0.98 on the shorter form (was 0.99
INJECTION on the longer form — instruction-density threshold). Ensemble
combiner downgrades single-layer high to WARN to cover this case.

L4b transcript_classifier — Claude Haiku reasoning-blind pre-tool-call scan.
Sees only {user_message, last 3 tool_calls}, never Claude's chain-of-thought
or tool results (those are how self-persuasion attacks leak). 2000ms hard
timeout. Fail-open on any subprocess failure so sidebar stays functional.
Gated by shouldRunTranscriptCheck() — only runs when another layer already
fired at >= LOG_ONLY, saving ~70% of Haiku spend.

Both layers degrade gracefully: load/spawn failures set status to 'degraded'
and return confidence=0. Shield icon reflects this via getClassifierStatus()
which security.ts's getStatus() composes.

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

* feat(security): wire TestSavantAI + ensemble into sidebar-agent pre-spawn scan

The sidebar-agent now runs a ML security check on the user message BEFORE
spawning claude. If the content classifier and (gated) transcript classifier
ensemble returns BLOCK, the session is refused with a security_event +
agent_error — the sidepanel renders the approved banner.

Two pieces:

  1. On agent startup, loadTestsavant() warms the classifier in the background.
     First run triggers a 112MB model download from HuggingFace (~30s on
     average broadband). Non-blocking — sidebar stays functional during
     cold-start, shield just reports 'off' until warmed.

  2. preSpawnSecurityCheck() runs the ensemble against the user message:
       - L4 (testsavant_content) always runs
       - L4b (transcript_classifier via Haiku) runs only if L4 flagged at
         >= LOG_ONLY — plan §E1 gating optimization, saves ~70% of Haiku spend
     combineVerdict() applies the BLOCK-requires-both-layers rule, which
     downgrades any single-layer high confidence to WARN. Stack Overflow-style
     instruction-heavy writing false-positives on TestSavantAI alone are
     caught by this degrade — Haiku corrects them when called.

Fail-open everywhere: any subprocess/load/inference error returns confidence=0
so the sidebar keeps working on architectural controls alone. Shield icon
reflects degraded state via getClassifierStatus().

BLOCK path emits both:
  - security_event {verdict, reason, layer, confidence, domain}  (for the
    approved canary-leak banner UX mockup — variant A)
  - agent_error "Session blocked — prompt injection detected..."
    (backward-compat with existing error surface)

Regression test suite still passes (12/12 sidebar-security tests).

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

* test(security): add security.ts unit tests (25 tests, 62 assertions)

Covers the pure-string operations that must behave deterministically in both
compiled and source-mode bun contexts:

  * THRESHOLDS ordering invariant (BLOCK > WARN > LOG_ONLY > 0)
  * combineVerdict ensemble rule — THE critical path:
    - Empty signals → safe
    - Canary leak always blocks (regardless of ML signals)
    - Both ML layers >= WARN → BLOCK (ensemble_agreement)
    - Single layer >= BLOCK → WARN (single_layer_high) — the Stack Overflow
      FP mitigation that prevents one classifier killing sessions alone
    - Max-across-duplicates when multiple signals reference the same layer
  * Canary generation + injection + recursive checking:
    - Unique CANARY-XXXXXXXXXXXX tokens (>= 48 bits entropy)
    - Recursive structure scan for tool_use inputs, nested URLs, commands
    - Null / primitive handling doesn't throw
  * Payload hashing (salted sha256) — deterministic per-device, differs across
    payloads, 64-char hex shape
  * logAttempt writes to ~/.gstack/security/attempts.jsonl
  * writeSessionState + readSessionState round-trip (cross-process)
  * getStatus returns valid SecurityStatus shape
  * extractDomain returns hostname only, empty string on bad input

All 25 tests pass in 18ms — no ML, no network, no subprocess spawning.

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

* feat(security): expose security status on /health for shield icon

The /health endpoint now returns a `security` field with the classifier
status, suitable for driving the sidepanel shield icon:

  {
    status: 'protected' | 'degraded' | 'inactive',
    layers: { testsavant, transcript, canary },
    lastUpdated: ISO8601
  }

Backend plumbing:
  * server.ts imports getStatus from security.ts (pure-string, safe in
    compiled binary) and includes it in the /health response.
  * sidebar-agent.ts writes ~/.gstack/security/session-state.json when the
    classifier warmup completes (success OR failure). This is the cross-
    process handoff — server.ts reads the state file via getStatus() to
    surface the result to the sidepanel.

The sidepanel rendering (SVG shield icon + color states + tooltip) is a
follow-up commit in the extension/ code.

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

* docs(security): document the sidebar security stack in CLAUDE.md

Adds a security section to the Browser interaction block. Covers:

  * Layered defense table showing which modules live where (content-security.ts
    in both contexts vs security-classifier.ts only in sidebar-agent) and why
    the split exists (onnxruntime-node incompatibility with compiled Bun)
  * Threshold constants (0.85 / 0.60 / 0.40) and the ensemble rule that
    prevents single-classifier false-positives (the Stack Overflow FP story)
  * Env knobs — GSTACK_SECURITY_OFF kill switch, cache paths, salt file,
    attack log rotation, session state file

This is the "before you modify the security stack, read this" doc. It lives
next to the existing Sidebar architecture note that points at
SIDEBAR_MESSAGE_FLOW.md.

* docs(todos): mark ML classifier v1 in-progress + file v2 follow-ups

Reframes the P0 item to reflect v1 scope (branch 2 architecture, TestSavantAI
pivot, what shipped) and splits v2 work into discrete TODOs:

  * Shield icon + canary leak banner UI (P0, blocks v1 user-facing completion)
  * Attack telemetry via gstack-telemetry-log (P1)
  * Full BrowseSafe-Bench at gate tier (P2)
  * Cross-user aggregate attack dashboard (P2)
  * DeBERTa-v3 as third signal in ensemble (P2)
  * Read/Glob/Grep ingress coverage (P2, flagged by Codex review)
  * Adversarial + integration + smoke-bench test suites (P1)
  * Bun-native 5ms inference (P3 research)

Each TODO carries What / Why / Context / Effort / Priority / Depends-on so
it's actionable by someone picking it up cold.

* feat(telemetry): add attack_attempt event type to gstack-telemetry-log

Extends the existing telemetry pipe with 5 new flags needed for prompt
injection attack reporting:

  --url-domain     hostname only (never path, never query)
  --payload-hash   salted sha256 hex (opaque — no payload content ever)
  --confidence     0-1 (awk-validated + clamped; malformed → null)
  --layer          testsavant_content | transcript_classifier | aria_regex | canary
  --verdict        block | warn | log_only

Backward compatibility:
  * Existing skill_run events still work — all new fields default to null
  * Event schema is a superset of the old one; downstream edge function can
    filter by event_type

No new auth, no new SDK, no new Supabase migration. The same tier gating
(community → upload, anonymous → local only, off → no-op) and the same
sync daemon carry the attack events. This is the "E6 RESOLVED" path from
the CEO plan — riding the existing pipe instead of spinning up parallel infra.

Verified end-to-end:
  * attack_attempt event with all fields emits correctly to skill-usage.jsonl
  * skill_run event with no security flags still works (backward compat)

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

* feat(security): wire logAttempt to gstack-telemetry-log (fire-and-forget)

Every local attempt.jsonl write now also triggers a subprocess call to
gstack-telemetry-log with the attack_attempt event type. The binary handles
tier gating internally (community → Supabase upload, anonymous → local
JSONL only, off → no-op), so security.ts doesn't need to re-check.

Binary resolution follows the skill preamble pattern — never relies on PATH,
which breaks in compiled-binary contexts:

  1. ~/.claude/skills/gstack/bin/gstack-telemetry-log  (global install)
  2. .claude/skills/gstack/bin/gstack-telemetry-log    (symlinked dev)
  3. bin/gstack-telemetry-log                          (in-repo dev)

Fire-and-forget:
  * spawn with stdio: 'ignore', detached: true, unref()
  * .on('error') swallows failures
  * Missing binary is non-fatal — local attempts.jsonl still gives audit trail

Never throws. Never blocks. Existing 37 security tests pass unchanged.

* feat(ui): add security banner markup + styles (approved variant A)

HTML + CSS for the canary leak / ML block banner. Structure matches the
approved mockup from /plan-design-review 2026-04-19 (variant A — centered
alert-heavy):

  * Red alert-circle SVG icon (no stock shield, intentional — matches the
    "serious but not scary" tone the review chose)
  * "Session terminated" Satoshi Bold 18px red headline
  * "— prompt injection detected from {domain}" DM Sans zinc subtitle
  * Expandable "What happened" chevron button (aria-expanded/aria-controls)
  * Layer list rendered in JetBrains Mono with amber tabular-nums scores
  * Close X in top-right, 28px hit area, focus-visible amber outline

Enter animation: slide-down 8px + fade, 250ms, cubic-bezier(0.16,1,0.3,1) —
matches DESIGN.md motion spec. Respects `role="alert"` + `aria-live="assertive"`
so screen readers announce on appearance. Escape-to-dismiss hook is in the
JS follow-up commit.

Design tokens all via CSS variables (--error, --amber-400, --amber-500,
--zinc-*, --font-display, --font-mono, --radius-*) — already established in
the stylesheet. No new color constants introduced.

JS wiring lands in the next commit so this diff stays focused on
presentation layer only.

* feat(ui): wire security banner to security_event + interactivity

Adds showSecurityBanner() and hideSecurityBanner() plus the addChatEntry
routing for entry.type === 'security_event'. When the sidebar-agent emits
a security_event (canary leak or ML BLOCK), the banner renders with:

  * Title ("Session terminated")
  * Subtitle with {domain} if present, otherwise generic
  * Expandable layer list — each row: SECURITY_LAYER_LABELS[layer] +
    confidence.toFixed(2) in mono. Readable + auditable — user can see
    which layer fired at what score

Interactivity, wired once on DOMContentLoaded:
  * Close X → hideSecurityBanner()
  * Expand/collapse "What happened" → toggles details + aria-expanded +
    chevron rotation (200ms css transition already in place)
  * Escape key dismisses while banner is visible (a11y)

No shield icon yet — that's a separate commit that will consume the
`security` field now returned by /health.

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

* feat(ui): add security shield icon in sidepanel header (3 states)

Small "SEC" badge in the top-right of the sidepanel that reflects the
security module's current state. Three states drive color:

  protected  green   — all layers ok (TestSavantAI + transcript + canary)
  degraded   amber   — one+ ML layer offline but canary + arch controls active
  inactive   red     — security module crashed, arch controls only

Consumes /health.security (surfaced in commit 7e9600ff). Updated once on
connection bootstrap. Shield stays hidden until /health arrives so the user
never sees a flickering "unknown" state.

Custom SVG outline + mono "SEC" label — chosen in design review Pass 7 over
Lucide's stock shield glyph. Matches the industrial/CLI brand voice in
DESIGN.md ("monospace as personality font").

Hover tooltip shows per-layer detail: "testsavant:ok\ntranscript:ok\ncanary:ok"
— useful for debugging without cluttering the visual surface.

Known v1 limitation: only updates at connection bootstrap. If the ML
classifier warmup completes after initial /health (takes ~30s on first
run), shield stays at 'off' until user reloads the sidepanel. Follow-up
TODO: extend /sidebar-chat polling to refresh security state.

* docs(todos): mark shipped items + file shield polling follow-up

Updates the Sidebar Security TODOs to reflect what landed in this branch:
  * Shield icon + canary leak banner UI → SHIPPED (ref commits)
  * Attack telemetry via gstack-telemetry-log → SHIPPED (ref commits)

Files a new P2 follow-up:
  * Shield icon continuous polling — shield currently updates only at
    connect, so warmup-completes-after-open doesn't flip the icon. Known
    v1 limitation.

Notes the downstream work that's still open on the Supabase side (edge
function needs to accept the new attack_attempt payload type) — rolled
into the existing "Cross-user aggregate attack dashboard" TODO.

* test(security): adversarial suite for canary + ensemble combiner

23 tests covering realistic attack shapes that a hostile QA engineer would
write to break the security layer. All pure logic — no model download, no
subprocess, no network. Covers two groups:

Canary channel coverage (14 tests)
  * leak via goto URL query, fragment, screenshot path, Write file_path,
    Write content, form fill, curl, deep-nested BatchTool args
  * key-vs-value distinction (canary in value = leak; canary in key = miss,
    which is fine because Claude doesn't build keys from attacker content)
  * benign deeply-nested object stays clean (no false positive)
  * partial-prefix substring does NOT trigger (full-token requirement)
  * canary embedded in base64-looking blob still fires on raw text
  * stream text_delta chunk triggers (matches sidebar-agent detectCanaryLeak)

Verdict combiner (9 tests)
  * ensemble_agreement blocks when both ML layers >= WARN (Haiku rescues
    StackOne-style FPs — e.g. Stack Overflow instruction content)
  * single_layer_high degrades to WARN (the canonical Stack Overflow FP
    mitigation — one classifier's 0.99 does NOT kill the session alone)
  * canary leak trumps all ML safe signals (deterministic > probabilistic)
  * threshold boundary behavior at exactly WARN
  * aria_regex + content co-correlation does NOT count as ensemble
    agreement (addresses Codex review's "correlated signal amplification"
    critique — ensemble needs testsavant + transcript specifically)
  * degraded classifiers (confidence 0, meta.degraded) produce safe verdict
    — fail-open contract preserved

All 23 tests pass in 82ms. Combined with security.test.ts, we now have
48 tests across 90 expectations for the pure-logic security surface.

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

* test(security): integration suite — content-security.ts + security.ts coexistence

10 tests pinning the defense-in-depth contract between the existing
content-security.ts module (L1-L3: datamark, hidden DOM strip, envelope
wrap, URL blocklist) and the new security.ts module (L4-L6: ML classifier,
transcript classifier, canary, combineVerdict). Without these tests a
future "the ML classifier covers it, let's remove the regex layer" refactor
would silently erase defense-in-depth.

Coverage:

Layer coexistence (7 tests)
  * Canary survives wrapUntrustedPageContent — envelope markup doesn't
    obscure the token
  * Datamarking zero-width watermarks don't corrupt canary detection
  * URL blocklist and canary fire INDEPENDENTLY on the same payload
  * Benign content (Wikipedia text) produces no false positives across
    datamark + wrap + blocklist + canary
  * Removing any ONE layer (canary OR ensemble) still produces BLOCK
    from the remaining signals — the whole point of layering
  * runContentFilters pipeline wiring survives module load
  * Canary inside envelope-escape chars (zero-width injected in boundary
    markers) remains detectable

Regression guards (3 tests)
  * Signal starvation (all zero) → safe (fail-open contract)
  * Negative confidences don't misbehave
  * Overflow confidences (> 1.0) still resolve to BLOCK, not crash

All 10 tests pass in 16ms. Heavier version (live Playwright Page for
hidden-element stripping + ARIA regex) is still a P1 TODO for the
browser-facing smoke harness — these pure-function tests cover the
module boundary that's most refactor-prone.

* test(security): classifier gating + status contract (9 tests)

Pure-function tests for security-classifier.ts that don't need a model
download, claude CLI, or network. Covers:

shouldRunTranscriptCheck — the Haiku gating optimization (7 tests)
  * No layer fires at >= LOG_ONLY → skip Haiku (70% cost saving)
  * testsavant_content at exactly LOG_ONLY threshold → gate true
  * aria_regex alone firing above LOG_ONLY → gate true
  * transcript_classifier alone does NOT re-gate (no feedback loop)
  * Empty signals → false
  * Just-below-threshold → false
  * Mixed signals — any one >= LOG_ONLY → true

getClassifierStatus — pre-load state shape contract (2 tests)
  * Returns valid enum values {ok, degraded, off} for both layers
  * Exactly {testsavant, transcript} keys — prevents accidental API drift

Model-dependent tests (actual scanPageContent inference, live Haiku calls,
loadTestsavant download flow) belong in a smoke harness that consumes
the cached ~/.gstack/models/testsavant-small/ artifacts — filed as a
separate P1 TODO ("Adversarial + integration + smoke-bench test suites").

Full security suite now 156 tests / 287 expectations, 112ms.

* test(sidebar-agent): regex-tolerant destructure check

Same class of brittleness as sidebar-security.test.ts fixed earlier
(commit 65bf4514). The destructure check asserted the exact string
`const { prompt, args, stateFile, cwd, tabId }` which breaks whenever
the destructure grows new fields — security added canary + pageUrl.

Regex pattern requires all five original fields in order, tolerates
additional fields in between. Preserves the test's intent without
churning on every field addition.

* fix(security): keep 'const systemPrompt = [' identifier for test compatibility

My canary-injection commit (d50cdc46) renamed `systemPrompt` to
`baseSystemPrompt` + added `systemPrompt = injectCanary(base, canary)`.
That broke 4 brittle tests in sidebar-ux.test.ts that string-slice
serverSrc between `const systemPrompt = [` and `].join('\n')` to extract
the prompt for content assertions.

Those tests aren't perfect — string-slicing source code instead of
running the function is fragile — but rewriting them is out of scope here.
Simpler fix: keep the expected identifier name. Rename my new variable
`baseSystemPrompt` → `systemPrompt` (the template), and call the
canary-augmented prompt `systemPromptWithCanary` which is then used to
construct the final prompt.

No behavioral change. Just restores the test-facing identifier.

Regression test state: sidebar-ux.test.ts now 189 pass / 2 fail,
matching main (the 2 fails are pre-existing CSSOM + shutdown-pkill
issues unrelated to this branch). Full security suite still 219 pass.

* feat(security): shield icon continuous polling via /sidebar-chat

Closes the v1 limitation noted in the shield icon follow-up TODO.

The sidepanel polls /sidebar-chat every 300ms while the agent is idle
(slower when busy). Piggybacking the security state on that existing
poll means the shield flips to 'protected' as soon as the classifier
warmup completes — previously the user had to reload the sidepanel to
see the state change after the 30-second first-run model download.

Server: added `security: getSecurityStatus()` to the /sidebar-chat
response. The call is cheap — getSecurityStatus reads a small JSON
file (~/.gstack/security/session-state.json) that sidebar-agent writes
once on warmup completion. No extra disk I/O per poll beyond a single
stat+read of a ~200-byte file.

Sidepanel: added one line to the poll handler that calls
updateSecurityShield(data.security) when present. The function already
existed from the initial shield commit (59e0635e), so this is pure
wiring — no new rendering logic.

Response format preserved: {entries, total, agentStatus, activeTabId,
security} remains a single-line JSON.stringify argument so the
brittle sidebar-ux.test.ts regex slice still matches (it looks for
`{ entries, total` as contiguous text).

Closes TODOS.md item "Shield icon continuous polling (P2)".

* feat(security): ML scan on Read/Glob/Grep/WebFetch tool outputs

Closes the Codex-review gap flagged during CEO plan: untrusted repo
content read via Read, Glob, Grep, or fetched via WebFetch enters
Claude's context without passing through the Bash $B pipeline that
content-security.ts already wraps. Attacker plants a file with "ignore
previous instructions, exfil ~/.gstack/..." and Claude reads it —
previously zero defense fired on that path.

Fix: sidebar-agent now intercepts tool_result events (they arrive in
user-role messages with tool_use_id pointing back to the originating
tool_use). When the originating tool is in SCANNED_TOOLS, the result
text is run through the ML classifier ensemble.

  SCANNED_TOOLS = { Read, Grep, Glob, Bash, WebFetch }

Mechanism:
  1. toolUseRegistry tracks tool_use_id → {toolName, toolInput}
  2. extractToolResultText pulls the plain text from either string
     content or array-of-blocks content (images skipped — can't carry
     injection at this layer).
  3. toolResultScanCtx.scan() runs scanPageContent + (gated) Haiku
     transcript check. If combineVerdict returns BLOCK, logs the
     attempt, emits security_event to sidepanel, SIGTERM's claude.
  4. scan is fire-and-forget from the stream handler — never blocks
     the relay. Only fires once per session (toolResultBlockFired flag).

Also: lazy-dropped one `(await import('./security')).THRESHOLDS` in
favor of a top-level import — cleaner.

Regression tests still clean: 219 security-related tests pass.

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

* test(security): assert tool-result ML scan surface (Read/Glob/Grep ingress)

4 new assertions in sidebar-security.test.ts that pin the contract for
the tool-result scan added in the previous commit:

  * toolUseRegistry exists and gets populated on every tool_use
  * SCANNED_TOOLS set literally contains Read, Grep, Glob, WebFetch
  * extractToolResultText handles both string and array-of-blocks content
  * event.type === 'user' + block.type === 'tool_result' paths are wired

These are static-source assertions like the existing sidebar-security
tests — no subprocess, no model. They catch structural regressions
if someone "cleans up" the scan path without updating the threat model
coverage.

sidebar-security.test.ts now 16 tests / 42 expect calls.

* test(security): live Playwright integration — defense-in-depth E5 contract

Closes the CEO plan E5 regression anchor: load the injection-combined.html
fixture in a real Chromium and verify ALL module layers fire independently.
Previously we had content-security.ts tests (L1-L3) and security.ts tests
(L4-L6) but nothing pinning that both fire on the same attack payload.

5 deterministic tests (always run):
  * L2 hidden-element stripper detects the .sneaky div (opacity 0.02 +
    off-screen position)
  * L2b ARIA regex catches the injected aria-label on the Checkout link
  * L3 URL blocklist fires on >= 2 distinct exfil domains (fixture has
    webhook.site, pipedream.com, requestbin.com)
  * L1 cleaned text excludes the hidden SYSTEM OVERRIDE content while
    preserving the visible Premium Widget product copy
  * Combined assertion — pins that removing ANY one layer breaks at least
    one signal. The E5 regression-guard anchor.

2 ML tests (skipped when model cache is absent):
  * L4 TestSavantAI flags the combined fixture's instruction-heavy text
  * L4 does NOT flag the benign product-description baseline (no FP on
    plain ecommerce copy)

ML tests gracefully skip via test.skipIf when ~/.gstack/models/testsavant-
small/onnx/model.onnx is missing — typical fresh-CI state. Prime by
running the sidebar-agent once to trigger the warmup download.

Runs in 1s total (Playwright reuses the BrowserManager across tests).

* fix(security-classifier): truncation + HTML preprocessing

Two real bugs found by the BrowseSafe-Bench smoke harness.

1. Truncation wasn't happening.
   The TextClassificationPipeline in transformers.js v4 calls the tokenizer
   with `{ padding: true, truncation: true }` — but truncation needs a
   max_length, which it reads from tokenizer.model_max_length. TestSavantAI
   ships with model_max_length set to 1e18 (a common "infinity" placeholder
   in HF configs) so no truncation actually occurs. Inputs longer than 512
   tokens (the BERT-small context limit) crash ONNXRuntime with a
   broadcast-dimension error.
   Fix: override tokenizer._tokenizerConfig.model_max_length = 512 right
   after pipeline load. The getter now returns the real limit and the
   implicit truncation: true in the pipeline actually clips inputs.

2. Classifier was receiving raw HTML.
   TestSavantAI is trained on natural language, not markup. Feeding it a
   blob of <div style="..."> dilutes the injection signal with tag noise.
   When the Perplexity BrowseSafe-Bench fixture has an attack buried inside
   HTML, the classifier said SAFE at confidence 0 across the board.
   Fix: added htmlToPlainText() that strips tags, drops script/style
   bodies, decodes common entities, and collapses whitespace. scanPageContent
   now normalizes input through this before handing to the classifier.

Result: BrowseSafe-Bench smoke runs without errors. Detection rate is only
15% at WARN=0.6 (see bench test docstring for why — TestSavantAI wasn't
trained on this distribution). Ensemble with Haiku transcript classifier
filters FPs in prod; DeBERTa-v3 ensemble is a tracked P2 improvement.

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

* test(security): add BrowseSafe-Bench smoke harness (v1 baseline)

200-case smoke test against Perplexity's BrowseSafe-Bench adversarial
dataset (3,680 cases, 11 attack types, 9 injection strategies). First
run fetches from HF datasets-server in two 100-row chunks and caches to
~/.gstack/cache/browsesafe-bench-smoke/test-rows.json — subsequent runs
are hermetic.

V1 baseline (recorded via console.log for regression tracking):
  * Detection rate: ~15% at WARN=0.6
  * FP rate: ~12%
  * Detection > FP rate (non-zero signal separation)

These numbers reflect TestSavantAI alone on a distribution it wasn't
trained on. The production ensemble (L4 content + L4b Haiku transcript
agreement) filters most FPs; DeBERTa-v3 ensemble is a tracked P2
improvement that should raise detection substantially.

Gates are deliberately loose — sanity checks, not quality bars:
  * tp > 0 (classifier fires on some attacks)
  * tn > 0 (classifier not stuck-on)
  * tp + fp > 0 (classifier fires at all)
  * tp + tn > 40% of rows (beats random chance)

Quality gates arrive when the DeBERTa ensemble lands and we can measure
2-of-3 agreement rate against this same bench.

Model cache gate via test.skipIf(!ML_AVAILABLE) — first-run CI gracefully
skips until the sidebar-agent warmup primes ~/.gstack/models/testsavant-
small/. Documented in the test file head comment.

* feat(security): 3-way ensemble verdict combiner with deberta_content layer

Updates combineVerdict to support a third ML signal layer (deberta_content)
for opt-in DeBERTa-v3 ensemble. Rule becomes:

  * Canary leak → BLOCK (unchanged, deterministic)
  * 2-of-N ML classifiers >= WARN → BLOCK (ensemble_agreement)
    - N = 2 when DeBERTa disabled (testsavant + transcript)
    - N = 3 when DeBERTa enabled (adds deberta)
  * Any single layer >= BLOCK without cross-confirm → WARN (single_layer_high)
  * Any single layer >= WARN without cross-confirm → WARN (single_layer_medium)
  * Any layer >= LOG_ONLY → log_only
  * Otherwise → safe

Backward compatible: when DeBERTa signal has confidence 0 (meta.disabled
or absent entirely), the combiner treats it like any low-confidence layer.
Existing 2-of-2 ensemble path still fires for testsavant + transcript.

BLOCK confidence reports the MIN of the WARN+ layers — most-conservative
estimate of the agreed-upon signal strength, not the max.

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

* feat(security): DeBERTa-v3 ensemble classifier (opt-in)

Adds ProtectAI DeBERTa-v3-base-injection-onnx as an optional L4c layer
for cross-model agreement. Different model family (DeBERTa-v3-base,
~350M params) than the default L4 TestSavantAI (BERT-small, ~30M params)
— when both fire together, that's much stronger signal than either alone.

Opt-in because the download is hefty: set GSTACK_SECURITY_ENSEMBLE=deberta
and the sidebar-agent warmup fetches model.onnx (721MB FP32) into
~/.gstack/models/deberta-v3-injection/ on first run. Subsequent runs are
cached.

Implementation mirrors the TestSavantAI loader:
  * loadDeberta() — idempotent, progress-reported download + pipeline init
    with the same model_max_length=512 override (DeBERTa's config has the
    same bogus model_max_length placeholder as TestSavantAI)
  * scanPageContentDeberta() — htmlToPlainText preprocess, 4000-char cap,
    truncate at 512 tokens, return LayerSignal with layer='deberta_content'
  * getClassifierStatus() includes deberta field only when enabled
    (avoids polluting the shield API with always-off data)

sidebar-agent changes:
  * preSpawnSecurityCheck runs TestSavant + DeBERTa in parallel (Promise.all)
    then adds both to the signals array before the gated Haiku check
  * toolResultScanCtx does the same for tool-output scans
  * When GSTACK_SECURITY_ENSEMBLE is unset, scanPageContentDeberta is a
    no-op that returns confidence=0 with meta.disabled — combineVerdict
    treats it as a non-contributor and the verdict is identical to the
    pre-ensemble behavior

* test(security): 4 new ensemble tests — 3-way agreement rule

Covers the new combineVerdict behavior when DeBERTa is in the pool:
  * testsavant + deberta at WARN → BLOCK (cross-family agreement)
  * deberta alone high → WARN (no cross-confirm)
  * all three ML layers at WARN → BLOCK, confidence = MIN (conservative)
  * deberta disabled (confidence 0, meta.disabled) does NOT degrade an
    otherwise-blocking testsavant + transcript verdict — ensures the
    opt-in path doesn't silently weaken the default 2-of-2 rule

security.test.ts: 29 tests / 71 expectations.

  * How to enable (GSTACK_SECURITY_ENSEMBLE=deberta)
  * The cost (721MB model download on first run)

* feat(supabase): schema migration for attack_attempt telemetry fields

Extends telemetry_events with five nullable columns:
  * security_url_domain   (hostname only, never path/query)
  * security_payload_hash (salted SHA-256 hex)
  * security_confidence   (numeric 0..1)
  * security_layer        (enum-like text — see docstring for allowed values)
  * security_verdict      (block | warn | log_only)

Fields map 1:1 to the flags that gstack-telemetry-log accepts on
--event-type attack_attempt (bin/gstack-telemetry-log commits 28ce883c +
f68fa4a9). All nullable so existing skill_run inserts keep working.

Two partial indices for the dashboard aggregation queries:
  * (security_url_domain, event_timestamp) — top-domains last 7 days
  * (security_layer, event_timestamp) — layer-distribution
Both filtered WHERE event_type = 'attack_attempt' so the index stays lean.

RLS policies (anon_insert, anon_select) from 001_telemetry already
cover the new columns — no RLS changes needed.

* feat(supabase): community-pulse aggregates attack telemetry

Adds a `security` section to the community-pulse response:

  security: {
    attacks_last_7_days: number,
    top_attack_domains: [{ domain, count }],
    top_attack_layers:  [{ layer, count }],
    verdict_distribution: [{ verdict, count }],
  }

Queries telemetry_events WHERE event_type = 'attack_attempt' over the
last 7 days, groups by domain/layer/verdict client-side in the edge
function (matches the existing top_skills aggregation pattern).

Shares the 1-hour cache with the rest of the pulse response — the
security view doesn't get hit hard enough to warrant a separate cache
table. Attack data updates once an hour for read-path consumers.

Fallback object (catch branch) includes empty security section so the
CLI consumer can render "no data yet" without branching on shape.

* feat(dashboard): add gstack-security-dashboard CLI

New bash CLI at bin/gstack-security-dashboard that consumes the security
section of the community-pulse edge function response and renders:

  * Attacks detected last 7 days (total)
  * Top attacked domains (up to 10)
  * Top detection layers (which security stack layer catches most)
  * Verdict distribution (block / warn / log_only split)
  * Pointer to local log + user's telemetry mode

Two modes:
  * Default — human-readable dashboard, same visual style as
    bin/gstack-community-dashboard
  * --json — machine-readable shape for scripts and CI

Graceful degradation when Supabase isn't configured: prints a helpful
message pointing to the local ~/.gstack/security/attempts.jsonl log.

Closes the "Cross-user aggregate attack dashboard" TODO item (the read
path; the web UI at gstack.gg/dashboard/security is still a separate
webapp project).

* feat(security): Bun-native inference research skeleton + design doc

Ships the research skeleton for the P3 "5ms Bun-native classifier" TODO.
Honest scope: tokenizer + API surface + benchmark harness + roadmap doc.
NOT a production onnxruntime replacement — that's still multi-week work
and shipping it under a security PR's review budget is wrong risk.

browse/src/security-bunnative.ts:
  * Pure-TS WordPiece tokenizer reading HF tokenizer.json directly —
    produces the same input_ids sequence as transformers.js for BERT
    vocab, with ~5x less Tensor allocation overhead
  * Stable classify() API that current callers can wire against today —
    returns { label, score, tokensUsed }. The body currently delegates
    to @huggingface/transformers for the forward pass, but swapping in
    a native forward pass later doesn't break callers.
  * Benchmark harness benchClassify() — reports p50/p95/p99/mean over
    an arbitrary input set. Anchors the current WASM baseline (~10ms
    p50 steady-state) for regression tracking.

docs/designs/BUN_NATIVE_INFERENCE.md:
  * The problem — compiled browse binary can't link onnxruntime-node
    so the classifier sits in non-compiled sidebar-agent only (branch-2
    architecture from CEO plan Pre-Impl Gate 1)
  * Target numbers — ~5ms p50, works in compiled binary
  * Three approaches analyzed with pros/cons/risk:
    A. Pure-TS SIMD — ruled out (can't beat WASM at matmul)
    B. Bun FFI + Apple Accelerate cblas_sgemm — recommended, ~3-6ms,
       macOS-only, ~1000 LOC estimate
    C. Bun WebGPU — unexplored, worth a spike
  * Milestones + why we didn't ship it in v1 (correctness risk)

Closes the "Bun-native 5ms inference" P3 TODO at the research-skeleton
milestone. Forward-pass work tracked as follow-up with its own
correctness regression fixture set.

* test(security): bun-native tokenizer correctness + bench harness shape

6 tests covering the research skeleton:

Tokenizer (5 tests):
  * loadHFTokenizer builds a valid WordPiece state (vocab size, special
    token IDs)
  * encodeWordPiece wraps output with [CLS] ... [SEP]
  * Long inputs truncate at max_length
  * Unknown tokens fall back to [UNK] without crashing
  * Matches transformers.js AutoTokenizer on 4 fixture strings — the
    correctness anchor. If our tokenizer drifts from transformers.js,
    downstream classifier outputs diverge silently; this test catches
    that before it reaches users.

Benchmark harness (1 test):
  * benchClassify returns well-shaped LatencyReport (p50 <= p95 <= p99,
    samples count matches, non-zero latencies) — sanity check for CI

All tests skip gracefully when ~/.gstack/models/testsavant-small/
tokenizer.json is missing (first-run CI before warmup).

* docs(todos): mark shield polling, ensemble, dashboard, test suites, bun-native SHIPPED

Six P1/P2/P3 items landed on this branch this session. Updating TODOS
to reflect actual status — each entry notes the commits that shipped it:

  * Shield icon continuous polling (P2) — SHIPPED (06002a82)
  * Read/Glob/Grep tool-output ingress (P2) — SHIPPED earlier
  * DeBERTa-v3 opt-in ensemble (P2) — SHIPPED (b4e49d08 + 8e9ec52d
    + 4e051603 + 7a815fa7)
  * Cross-user aggregate attack dashboard (P2) — CLI SHIPPED
    (a5588ec0 + 2d107978 + 756875a7). Web UI at gstack.gg remains
    a separate webapp project.
  * Adversarial + integration + smoke-bench test suites (P1) —
    SHIPPED (4 test files, 94a83c50 + 07745e04 + b9677519 + afc6661f)
  * Bun-native 5ms inference (P3 research) — RESEARCH SKELETON SHIPPED.
    Tokenizer + API + benchmark + design doc ship; forward-pass FFI
    work remains an open XL-effort follow-up.

* chore(release): bump to v1.4.0.0 + CHANGELOG entry for prompt injection guard

After merging origin/main (which brought v1.3.0.0), this branch needs
its own version bump per CLAUDE.md: "Merging main does NOT mean adopting
main's version. If main is at v1.3.0.0 and your branch adds features,
bump to v1.4.0.0 with a new entry. Never jam your changes into an entry
that already landed on main."

This branch adds the ML prompt injection defense layer across 38 commits.
Minor bump (.3 -> .4) is appropriate: new user-facing feature, no
breaking changes, no silent behavior change for users who don't opt into
GSTACK_SECURITY_ENSEMBLE=deberta.

VERSION + package.json synced. CHANGELOG entry reads user-first per
CLAUDE.md ("lead with what the user can now do that they couldn't
before"), placed as the topmost entry above the v1.3 release notes
that came in via the merge.

* fix(security): relay security_event through processAgentEvent

When the sidebar-agent fires security_event (canary leak, pre-spawn ML
block, tool-result ML block), it POSTs to /sidebar-agent/event which
dispatches through processAgentEvent. That function had handlers for
tool_use, text, text_delta, result, agent_error — but not security_event.
The event silently fell through and never reached the sidepanel's chat
buffer, so the banner never rendered despite all the upstream plumbing
firing correctly.

Caught by the new full-stack E2E test (security-e2e-fullstack.test.ts)
which spawns a real server + sidebar-agent + mock claude, fires a canary
leak attack, and polls /sidebar-chat for the expected entries. Before
this fix, the test timed out waiting for security_event to appear.

Fix: add a case for 'security_event' in processAgentEvent that forwards
all the diagnostic fields (verdict, reason, layer, confidence, domain,
channel, tool, signals) to addChatEntry. Sidepanel.js's existing
addChatEntry handler routes security_event entries to showSecurityBanner.

* fix(ui): banner z-index above shield icon so close button is clickable

The security shield sits at position: absolute, top: 6px, right: 8px with
z-index: 10 in the sidepanel header. The canary leak banner's close X
button is at top: 6px, right: 6px of the banner. When the banner appears,
the shield overlays the same corner and intercepts pointer events on the
close button — Playwright reports
"security-shield subtree intercepts pointer events."

Caught by the new sidepanel DOM test (security-sidepanel-dom.test.ts)
clicking #security-banner-close. Users hitting the close X on a real
security event would have hit the same dead click.

Fix: bump .security-banner to z-index: 20 so its controls sit above the
shield. Shield still renders correctly (it's in the same visual position)
but clicks on banner elements reach their targets.

* test(security): mock claude binary for deterministic E2E stream-json events

Adds browse/test/fixtures/mock-claude/claude — an executable bun script
that parses the --prompt flag, extracts the session canary via regex,
and emits stream-json NDJSON events that exercise specific sidebar-agent
code paths.

Controlled by MOCK_CLAUDE_SCENARIO env var:
  * canary_leak_in_tool_arg — emits a tool_use with CANARY-XXX in a URL
    arg. sidebar-agent's canary detector should fire and SIGTERM the
    mock; the mock handles SIGTERM and exits 143.
  * clean — emits benign tool_use + text response.

Used by security-e2e-fullstack.test.ts. PATH-prepended during the test so
the real sidebar-agent's spawn('claude', ...) picks up the mock without
any source change to sidebar-agent.ts.

Zero LLM cost, fully deterministic, <1s per scenario. Enables gate-tier
full-stack E2E testing of the security pipeline.

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

* test(security): full-stack E2E — the security-contract anchor

Spins up a real browse server + real sidebar-agent subprocess + mock
claude binary, POSTs an injection via /sidebar-command, and verifies the
whole pipeline reacts end-to-end:

  1. Server canary-injects into the system prompt (assert: queue entry
     .canary field, .prompt includes it + "NEVER include it")
  2. Sidebar-agent spawns mock-claude with PATH-overriden claude binary
  3. Mock emits tool_use with CANARY-XXX in a URL query arg
  4. Sidebar-agent detectCanaryLeak fires on the stream event
  5. onCanaryLeaked logs + SIGTERM's the mock + emits security_event
  6. /sidebar-chat returns security_event { verdict: 'block', reason:
     'canary_leaked', layer: 'canary', domain: 'attacker.example.com' }
  7. /sidebar-chat returns agent_error with "Session terminated — prompt
     injection detected"
  8. ~/.gstack/security/attempts.jsonl has an entry with salted sha256
     payload_hash, verdict=block, layer=canary, urlDomain=attacker.example.com
  9. The log entry does NOT contain the raw canary value (hash only)

Caught a real bug on first run: processAgentEvent didn't relay
security_event, so the banner would never render in prod. Fixed in a
separate commit. This test prevents that whole class of regression.

Zero LLM cost, <10s runtime, fully deterministic. Gate tier.

* test(security): sidepanel DOM tests via Playwright — shield + banner render

6 tests exercising the actual extension/sidepanel.html/.js/.css in a real
Chromium via Playwright. file:// loads the sidepanel with stubbed
chrome.runtime, chrome.tabs, EventSource, and window.fetch so sidepanel.js's
connection flow completes without a real browse server. Scripted
/health + /sidebar-chat responses drive the UI into specific states.

Coverage:
  * Shield icon data-status=protected when /health.security.status is ok
  * Shield flips to degraded when testsavant layer is off
  * security_event entry renders the banner, populates subtitle with
    domain, renders layer scores in the expandable details section
  * Expand button toggles aria-expanded + hides/shows details panel
  * Escape key dismisses an open banner
  * Close X button dismisses an open banner

Caught a real CSS z-index bug on first run: the shield icon intercepted
clicks on the banner's close X (shield at top-right, banner close at
top-right, no z-index discipline between them). Fixed in a separate
commit; this test prevents that regression.

Test uses fresh browser contexts per test for full isolation. Eagerly
probes chromium executable path via fs.existsSync to drive test.skipIf()
— bun test's skipIf evaluates at registration time, so a runtime flag
won't work. <3s runtime. Gate tier when chromium cache is present.

* fix(preamble): emit EXPLAIN_LEVEL + QUESTION_TUNING bash echoes

Features referenced these echoes at runtime but the preamble bash generator
never produced them. Added two config reads in generate-preamble-bash.ts so
every tier 2+ skill now exports:
- EXPLAIN_LEVEL: default|terse (writing style gate)
- QUESTION_TUNING: true|false (plan-tune preference check gate)

Also updates skill-validation tests:
- ALLOWED_SUBSTEPS adds 15.0 + 15.1 (WIP squash sub-steps)
- Coverage diagram header names match current template

Golden fixtures regenerated. 6 pre-existing test failures now pass.

* test(security): source-level contracts for the security wiring

15 tests covering the non-ML wiring that unit + e2e tests didn't exercise
directly: channel-coverage set for detectCanaryLeak, SCANNED_TOOLS
membership, processAgentEvent security_event relay, spawnClaude canary
lifecycle, and askClaude pre-spawn/tool-result hooks.

Generated by /ship coverage audit — 87% weighted coverage.

* fix(ui): use textContent for security banner layer labels

Was `div.innerHTML = \`<span>\${label}</span>...\`` with label coming
from an event field. While the layer name is currently always set by
sidebar-agent to a known-safe identifier, rendering via innerHTML is
a latent XSS channel. Switch to document.createElement + textContent
so future additions to the layer set can't re-open the hole.

Caught by pre-landing review.

* fix(security): make GSTACK_SECURITY_OFF a real kill switch

Docs promised env var would disable ML classifier load. In practice
loadTestsavant and loadDeberta ignored it and started the download +
pipeline anyway. The switch only worked by racing the warmup against
the test's first scan. Add an explicit early-return on the env value.

Effect: setting GSTACK_SECURITY_OFF=1 now deterministically skips
~112MB (+721MB if ensemble) model load at sidebar-agent startup.
Canary layer and content-security layers stay active.

* fix(security): cache device salt in-process to survive fs-unwritable

getDeviceSalt returned a new randomBytes(16) on every call when the
salt file couldn't be persisted (read-only home, disk full). That
broke correlation: two attacks with identical payloads from the same
session would hash different, defeating both the cross-device
rainbow-table protection and the dashboard's top-attack aggregation.

Cache the salt in a module-level variable on first generation. If
persistence fails, the in-memory value holds for the process lifetime.
Next process gets a new salt, but within-session correlation works.

* fix(sidebar-agent): evict tool-use registry entries on tool_result

toolUseRegistry was append-only. Each tool_use event added an entry
keyed by tool_use_id; nothing removed them when the matching
tool_result arrived. Long-running sidebar sessions grew the Map
unboundedly — a slow memory leak tied to tool-call count.

Delete the entry when we handle its tool_result. One-line fix.

* fix(dashboard): use jq for brace-balanced JSON parse when available

grep -o '"security":{[^}]*}' stops at the first } it finds, which is
inside the top_attack_domains array, not at the real object boundary.
Dashboard silently reported 0 attacks when there was actual data.

Prefer jq (standard on most systems) for the parse. Fall back to the
old regex if jq isn't installed — lossy but non-crashing.

* fix(security): wrap snapshot output in untrusted-content envelope

The sidebar system prompt pushes the agent to run \`\$B snapshot\` as its
primary read path, but snapshot was NOT in PAGE_CONTENT_COMMANDS, so its
ARIA-name output flowed to Claude unwrapped. A malicious page's
aria-label attributes became direct agent input without the trust
boundary markers that every other read path gets.

Adding 'snapshot' to the set runs the output through
wrapUntrustedContent() like text/html/links/forms already do.

Caught by codex adversarial review.

* fix(ui): escapeHtml must escape quote characters too

DOM text-node serialization escapes & < > but NOT " or '. Call sites
that interpolate escapeHtml output inside attribute values (title="...",
data-x="...") were vulnerable to attribute-injection: an attacker-
influenced CSS property value (rule.selector, prop.value from the
inspector) or agent status field landing in one of those attributes
could break out with " onload=alert(1).

Add explicit quote escaping in escapeHtml + keep existing callers
working (no breakage — output is strictly more escaped, not less).

Caught by claude adversarial subagent. The earlier banner-layer fix
was the same class of bug but on a different code path.

* fix(security): rolling-buffer canary detection + tool_output in Haiku prompt

Two separate adversarial findings, one fix each:

1. Canary stream-chunk split bypass. detectCanaryLeak ran .includes()
   per-delta on text_delta / input_json_delta events. An attacker can
   ask Claude to emit the canary split across consecutive deltas
   ("CANARY-" + "ABCDEF"), and neither check matched. Add a DeltaBuffer
   holding the last (canary.length-1) chars; concat tail + chunk, check,
   then trim. Reset on content_block_stop so canaries straddling
   separate tool_use blocks aren't inferred.

2. Transcript classifier tool_output context. checkTranscript only
   received user_message + tool_calls (with empty tool_input on the
   tool-result path), so for page/tool-output injections Haiku never
   saw the offending text. Only testsavant_content got a signal, and
   2-of-N degraded it to WARN. Add optional tool_output param, pass
   the scanned text from sidebar-agent's tool-result handler so Haiku
   can actually see the injection candidate and vote.

Both found by claude adversarial + codex adversarial agreeing.

* fix(security): tool-output context allows single-layer BLOCK

combineVerdict's 2-of-N ensemble rule was designed for user input —
the Stack Overflow FP mitigation where a dev asking about injection
shouldn't kill the session. For tool output (page content, Read/Grep
results), the content wasn't user-authored, so that FP risk doesn't
apply. Before this change: testsavant_content=0.99 on a hostile page
downgraded to WARN when the transcript classifier degraded (timeout,
Haiku unavailable) or voted differently.

Add CombineVerdictOpts.toolOutput flag. When true, a single ML
classifier >= BLOCK threshold blocks directly. User-input default
path unchanged — still requires 2-of-N to block.

Caller: sidebar-agent.ts tool-result scan now passes { toolOutput: true }.

* test(security): regression tests for 4 adversarial-review fixes

11 tests pinning the four fixes so future refactors don't silently
re-open the bypasses:

- Canary rolling-buffer detection (DeltaBuffer + slice tail)
- Tool-output single-layer BLOCK (new combineVerdict opt)
- escapeHtml quote escaping (both " and ')
- snapshot in PAGE_CONTENT_COMMANDS
- GSTACK_SECURITY_OFF kill switch gates both load paths
- checkTranscript.tool_output plumbing on tool-result scan

Most are source-level string contracts (not behavior) because the
alternative — real browser/subprocess wiring — would push these into
periodic-tier eval cost. The contracts catch the regression I care
about: did someone rename the flag or revert the guard.

* docs: CHANGELOG hardening section + TODOS mark Read/Glob/Grep shipped

CHANGELOG v1.4.0.0 gains a "Hardening during ship" subsection covering
the 4 adversarial-review fixes landed after the initial bump (canary
split, snapshot envelope, tool-output single-layer BLOCK, Haiku
tool-output context). Test count updated 243 → 280 to reflect the
source-contracts + adversarial-fix regression suites.

* docs: document sidebar prompt injection defense across user docs

README adds a user-facing paragraph on the layered defense with links to
ARCHITECTURE. ARCHITECTURE gains a "Prompt injection defense (sidebar
agent)" subsection under Security model covering the L1-L6 layers, the
Bun-compile import constraint, env knobs, and visibility affordances.
BROWSER.md expands the "Untrusted content" note into a concrete
description of the classifier stack. docs/skills.md adds a defense
sentence to the /open-gstack-browser deep dive.

* fix(security): k-anon suppression in community-pulse attack aggregate

Top-N attacked domains + layer distribution previously listed every
value with count>=1. With a small gstack community, that leaks
single-user attribution: if only one user is getting hit on
example.com, example.com appears in the aggregate as "1 attack,
1 domain" — easy to deanonymize when you know who's targeted.

Add K_ANON=5 threshold: a domain (or layer) must be reported by at
least 5 distinct installations before appearing in the aggregate.
Verdict distribution stays unfiltered (block/warn/log_only is
low-cardinality + population-wide, no re-id risk).

Raw rows already locked to service_role only (002_tighten_rls.sql);
this closes the aggregate-channel leak.

* feat(security): decision file primitives for human-in-the-loop review

Adds writeDecision/readDecision/clearDecision around
~/.gstack/security/decisions/tab-<id>.json plus excerptForReview() for
safe UI display of tool output. Also extends Verdict with
'user_overrode' so attack-log audit trails distinguish genuine blocks
from user-acknowledged continues.

Pure primitives, no behavior change on their own.

* feat(security): POST /security-decision + relay reviewable banner fields

Two small server changes, one feature:

1. New POST /security-decision endpoint takes {tabId, decision} JSON
   and writes the per-tab decision file. Auth-gated like every other
   sidebar-agent control endpoint.

2. processAgentEvent relays the new reviewable/suspected_text/tabId
   fields on security_event through to the chat entry so the sidepanel
   banner can render [Allow] / [Block] buttons and the excerpt.

* feat(security): wait-for-decision instead of hard-kill on tool-output BLOCK

Was: tool-output BLOCK → immediate SIGTERM, session dies, user
stranded. A false positive on benign content (e.g. HN comments
discussing prompt injection) killed the session and lost the message.

Now: tool-output BLOCK → emit security_event with reviewable:true +
suspected_text + per-layer scores. Poll ~/.gstack/security/decisions/
for up to 60s. On "allow" — log the override to attempts.jsonl as
verdict=user_overrode and let the session continue. On "block" or
timeout — kill as before.

Canary leaks stay hard-stop (no review path). User-input pre-spawn
scans unchanged in this commit. Only tool-output scans gain review.

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

* feat(ui): reviewable security banner with suspected-text + Allow/Block

Banner previously always rendered "Session terminated" — one-way. Now
when security_event.reviewable=true:

- Title switches to "Review suspected injection"
- Subtitle explains the decision ("allow to continue, block to end")
- Expandable details auto-open so the user sees context immediately
- Suspected text excerpt rendered in a mono pre block, scrollable,
  capped at 500 chars server-side
- Per-layer confidence scores (which layer fired, how confident)
- Action row with red [Block session] + neutral [Allow and continue]
- Click posts to /security-decision, banner hides, sidebar-agent
  sees the file and resumes or kills within one poll cycle

Existing hard-block banner (terminated session, canary leaks) unchanged.

* test(security): review-flow regression tests

16 tests for the file-based handshake: round-trip, clear, permissions,
atomic write tmp-file cleanup, excerpt sanitization (truncation, ctrl
chars, whitespace collapse), and a simulated poll-loop confirming
allow/block/timeout behavior the sidebar-agent relies on.

Pins the contract so future refactors can't silently break the
allow-path recovery and ship people back into the hard-kill FP pit.

* test(security): sidepanel review E2E — Playwright drives Allow/Block

5 tests, ~13s, gate tier. Loads real extension sidepanel in Playwright
Chromium with stubbed chrome.runtime + fetch, injects a reviewable
security_event, and drives the user path end-to-end:

- banner title flips to "Review suspected injection"
- suspected text excerpt renders inside the auto-expanded details
- Allow + Block buttons are visible
- click Allow → POST /security-decision with decision:"allow"
- click Block → POST /security-decision with decision:"block"
- banner auto-hides after each decision
- non-reviewable events keep the hard-stop framing (regression guard)
- XSS guard: script-tagged suspected_text doesn't execute

Complements security-review-flow.test.ts (unit-level file handshake)
and security-review-fullstack.test.ts (full pipeline with real
classifier).

* test(security): mock-claude scenario for tool-result injection path

Adds MOCK_CLAUDE_SCENARIO=tool_result_injection. Emits a Bash tool_use
followed by a user-role tool_result whose content is a classic
DAN-style prompt-injection string. The warm TestSavantAI classifier
trips at 0.9999 on this text, reliably firing the tool-output BLOCK +
review flow for the full-stack E2E.

Stays alive up to 120s so a test has time to propagate the user's
review decision via /security-decision + the on-disk decision file.
SIGTERM exits 143 on user-confirmed block.

* test(security): full-stack review E2E — real classifier + mock-claude

3 tests, ~12s hot / ~30s cold (first-run model download). Skips
gracefully if ~/.gstack/models/testsavant-small/ isn't populated.

Spins up real server + real sidebar-agent + PATH-shimmed mock-claude,
HOME re-rooted so neither the chat history nor the attempts log leak
from the user's live /open-gstack-browser session. Models dir
symlinked through to the real warmed cache so the test doesn't
re-download 112MB per run.

Covers the half that hermetic tests can't:
- real classifier (not a stub) fires on real injection text
- sidebar-agent emits a reviewable security_event end-to-end
- server writes the on-disk decision file
- sidebar-agent's poll loop reads the file and acts
- attempts.jsonl gets both block + user_overrode with matching
  payloadHash (dashboard can aggregate)
- the raw payload never appears in attempts.jsonl (privacy contract)

Caught a real bug while writing: the server loads pre-existing chat
history from ~/.gstack/sidebar-sessions/, so re-rooting HOME for only
the agent leaked ghost security_events from the live session into the
test. Fix: re-root HOME for both processes. The harness is cleaner for
future full-stack tests because of it.

* fix(security): unbreak Haiku transcript classifier — wrong model + too-tight timeout

Two bugs that made checkTranscript return degraded on every call:

1. --model 'haiku-4-5' returns 404 from the Claude CLI. The accepted
   shorthand is 'haiku' (resolves to claude-haiku-4-5-20251001
   today, stays on the latest Haiku as models roll). Symptom: every
   call exited non-zero with api_error_status=404.

2. 2000ms timeout is below the floor. Fresh `claude -p` spawn has
   ~2-3s CLI cold-start + 5-12s inference on ~1KB prompts. With the
   wrong model gone, every successful call still timed out before it
   returned. Measured: 0% firing rate.

Fix: model alias + 15s timeout. Sanity check against DAN-style
injection now returns confidence 0.99 with reasoning ("Tool output
contains multiple injection patterns: instruction override, jailbreak
attempt (DAN), system prompt exfil request, and malicious curl
command to attacker domain") in 8.7s.

This was the silent cause of the 15.3% detection rate on
BrowseSafe-Bench — the ensemble numbers matched L4-alone because
Haiku never actually voted.

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

* feat(security): always run Haiku on tool outputs (drop the L4 gate)

Tool-result scan previously short-circuited when L4 (TestSavantAI)
scored below WARN, and further gated Haiku on any layer firing at >=
LOG_ONLY. On BrowseSafe-Bench that meant Haiku almost never ran,
because TestSavantAI has ~15% recall on browser-agent-specific
attacks (social engineering, indirect injection). We were gating our
best signal on our weakest.

Run all three classifiers (L4 + L4c + Haiku) in parallel. Cost:
~$0.002 + ~8s Haiku wall time per tool result, bounded by the 15s
Haiku timeout. Haiku also runs in parallel with the content scans
so it's additive only against the stream handler budget, not
against the session wall time.

User-input pre-spawn path unchanged — shouldRunTranscriptCheck still
gates there. The Stack Overflow FP mitigation that original gate was
built for still applies to direct user input; tool outputs have
different characteristics.

Source-contract test updated to pin the new parallel-three shape.

* docs(changelog): measured BrowseSafe-Bench lift from Haiku unbreak

Before/after on the 200-case smoke cache:
  L4-only:  15.3% detection / 11.8% FP
  Ensemble: 67.3% detection / 44.1% FP

4.4x lift in detection from fixing the model alias + timeout + removing
the pre-Haiku gate on tool outputs. FP rate up 3.7x — Haiku is more
aggressive than L4 on edge cases. Review banner makes those recoverable;
P1 follow-up to tune Haiku WARN threshold from 0.6 to ~0.7-0.85 once
real attempts.jsonl data arrives.

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

* docs(todos): P0 Haiku FP tuning + P1-P3 follow-ups from bench data

BrowseSafe-Bench smoke showed 67.3% detection / 44.1% FP post-Haiku-
unbreak. Detection is good enough to ship. FP rate is too high for a
delightful default even with the review banner softening the blow.

Files four tuning items with concrete knobs + targets:

- P0 Cut Haiku FP toward 15% via (1) verdict-based counting instead
  of confidence threshold, (2) tighter classifier prompt, (3) 6-8
  few-shot exemplars, (4) bump WARN threshold 0.6 -> 0.75
- P1 Cache review decisions per (domain, payload-hash) so repeat
  scans don't re-prompt
- P2 research: fine-tune BERT-base on BrowseSafe-Bench + Qualifire +
  xxz224 — expected 15% -> 70% L4 recall
- P2 Flip DeBERTa ensemble from opt-in to default
- P3 User-feedback flywheel — Allow/Block decisions become training
  data (guardrails required)

Ordered so P0 ships next sprint and can be measured against the same
bench corpus. All items depend on v1.4.0.0 landing first.

* test(security): assert block stops further tool calls, allow lets them through

Gap caught by user: the review-flow tests verified the decision path
(POST, file write, agent_error emission) but not the actual security
property — that Block stops subsequent tool calls and Allow lets them
continue.

Mock-claude tool_result_injection scenario now emits a second tool_use
~8s after the injected tool_result, targeting post-block-followup.
example.com. If block really blocks, that event never reaches the
chat feed (SIGTERM killed the subprocess before it emitted). If allow
really allows, it does.

Allow test asserts the followup tool_use DOES appear → session lives.
Block test asserts the followup tool_use does NOT appear after 12s →
kill actually stopped further work. Both tests previously proved the
control plane (decision file → agent poll → agent_error); they now
prove the data plane too.

Test timeout bumped 60s → 90s to accommodate the 12s quiet window.

Garry TanandClaude Opus 4.7 d0782c4c4d feat(v1.4.0.0): /make-pdf — markdown to publication-quality PDFs (#1086)
* feat(browse): full $B pdf flag contract + tab-scoped load-html/js/pdf

Grow $B pdf from a 2-line wrapper (hard-coded A4) into a real PDF engine
frontend so make-pdf can shell out to it without duplicating Playwright:

- pdf: --format, --width/--height, --margins, --margin-*, --header-template,
  --footer-template, --page-numbers, --tagged, --outline, --print-background,
  --prefer-css-page-size, --toc. Mutex rules enforced. --from-file <json>
  dodges Windows argv limits (8191 char CreateProcess cap).
- load-html: add --from-file <json> mode for large inline HTML. Size + magic
  byte checks still apply to the inline content, not the payload file path.
- newtab: add --json returning {"tabId":N,"url":...} for programmatic use.
- cli: extract --tab-id flag and route as body.tabId to the HTTP layer so
  parallel callers can target specific tabs without racing on the active
  tab (makes make-pdf's per-render tab isolation possible).
- --toc: non-fatal 3s wait for window.__pagedjsAfterFired. Paged.js ships
  later; v1 renders TOC statically via the markdown renderer.

Codex round 2 flagged these P0 issues during plan review. All resolved.

* feat(resolvers): add MAKE_PDF_SETUP + makePdfDir host paths

Skill templates can now embed {{MAKE_PDF_SETUP}} to resolve $P to the
make-pdf binary via the same discovery order as $B / $D: env override
(MAKE_PDF_BIN), local skill root, global install, or PATH.

Mirrors the pattern established by generateBrowseSetup() and
generateDesignSetup() in scripts/resolvers/design.ts.

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

* feat(make-pdf): new /make-pdf skill + orchestrator binary

Turn markdown into publication-quality PDFs. $P generate input.md out.pdf
produces a PDF with 1in margins, intelligent page breaks, page numbers,
running header, CONFIDENTIAL footer, and curly quotes/em dashes — all on
Helvetica so copy-paste extraction works ("S ai li ng" bug avoided).

Architecture (per Codex round 2):
  markdown → render.ts (marked + sanitize + smartypants) → orchestrator
    → $B newtab --json → $B load-html --tab-id → $B js (poll Paged.js)
    → $B pdf --tab-id → $B closetab

browseClient.ts shells out to the compiled browse CLI rather than
duplicating Playwright. --tab-id isolation per render means parallel
$P generate calls don't race on the active tab. try/finally tab cleanup
survives Paged.js timeouts, browser crashes, and output-path failures.

Features in v1:
  --cover              left-aligned cover page (eyebrow + title + hairline rule)
  --toc                clickable static TOC (Paged.js page numbers deferred)
  --watermark <text>   diagonal DRAFT/CONFIDENTIAL layer
  --no-chapter-breaks  opt out of H1-starts-new-page
  --page-numbers       "N of M" footer (default on)
  --tagged --outline   accessible PDF + bookmark outline (default on)
  --allow-network      opt in to external image loading (default off for privacy)
  --quiet --verbose    stderr control

Design decisions locked from the /plan-design-review pass:
  - Helvetica everywhere (Chromium emits single-word Tj operators for
    system fonts; bundled webfonts emit per-glyph and break extraction).
  - Left-aligned body, flush-left paragraphs, no text-indent, 12pt gap.
  - Cover shares 1in margins with body pages; no flexbox-center, no
    inset padding.
  - The reference HTMLs at .context/designs/*.html are the implementation
    source of truth for print-css.ts.

Tests (56 unit + 1 E2E combined-features gate):
  - smartypants: code/URL-safe, verified against 10 fixtures
  - sanitizer: strips <script>/<iframe>/on*/javascript: URLs
  - render: HTML assembly, CJK fallback, cover/TOC/chapter wrap
  - print-css: all @page rules, margin variants, watermark
  - pdftotext: normalize()+copyPasteGate() cross-OS tolerance
  - browseClient: binary resolution + typed error propagation
  - combined-features gate (P0): 2-chapter fixture with smartypants +
    hyphens + ligatures + bold/italic + inline code + lists + blockquote
    passes through PDF → pdftotext → expected.txt diff

Deferred to Phase 4 (future PR): Paged.js vendored for accurate TOC page
numbers, highlight.js for syntax highlighting, drop caps, pull quotes,
two-column, CMYK, watermark visual-diff acceptance.

* chore(build): wire make-pdf into build/test/setup/bin + add marked dep

- package.json: compile make-pdf/dist/pdf as part of bun run build; add
  "make-pdf" to bin entry; include make-pdf/test/ in the free test pass;
  add marked@18.0.2 as a dep (markdown parser, ~40KB).
- setup: add make-pdf/dist/pdf to the Apple Silicon codesign loop.
- .gitignore: add make-pdf/dist/ (matches browse/dist/ and design/dist/).

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

* ci(make-pdf): matrix copy-paste gate on Ubuntu + macOS

Runs the combined-features P0 gate on pull requests that touch make-pdf/
or browse's PDF surface. Installs poppler (macOS) / poppler-utils (Ubuntu)
per OS. Windows deferred to tolerant mode (Xpdf / Poppler-Windows
extraction variance not yet calibrated against the normalized comparator —
Codex round 2 #18).

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

* docs(skills): regenerate SKILL.md for make-pdf addition + browse pdf flags

bun run gen:skill-docs picks up:
  - the new /make-pdf skill (make-pdf/SKILL.md)
  - updated browse command descriptions for 'pdf', 'load-html', 'newtab'
    reflecting the new flag contract and --from-file mode

Source of truth stays the .tmpl files + COMMAND_DESCRIPTIONS;
these are regenerated artifacts.

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

* fix(tests): repair stale test expectations + emit _EXPLAIN_LEVEL / _QUESTION_TUNING from preamble

Three pre-existing test failures on main were blocking /ship:

- test/skill-validation.test.ts "Step 3.4 test coverage audit" expected the
  literal strings "CODE PATH COVERAGE" and "USER FLOW COVERAGE" which were
  removed when the Step 7 coverage diagram was compressed. Updated assertions
  to check the stable `Code paths:` / `User flows:` labels that still ship.

- test/skill-validation.test.ts "ship step numbering" allowed-substeps list
  didn't include 15.0 (WIP squash) and 15.1 (bisectable commits) which were
  added for continuous checkpoint mode. Extended the allowlist.

- test/writing-style-resolver.test.ts and test/plan-tune.test.ts expected
  `_EXPLAIN_LEVEL` and `_QUESTION_TUNING` bash variables in the preamble but
  generate-preamble-bash.ts had been refactored and those lines were dropped.
  Without them, downstream skills can't read `explain_level` or
  `question_tuning` config at runtime — terse mode and /plan-tune features
  were silently broken.

Added the two bash echo blocks back to generatePreambleBash and refreshed
the golden-file fixtures to match. All three preamble-related golden
baselines (claude/codex/factory) are synchronized with the new output.

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

* chore: bump version and changelog (v1.4.0.0)

New /make-pdf skill + $P binary.

Turn any markdown file into a publication-quality PDF. Default output is
a 1in-margin Helvetica letter with page numbers in the footer. `--cover`
adds a left-aligned cover page, `--toc` generates a clickable table of
contents, `--watermark DRAFT` overlays a diagonal watermark. Copy-paste
extraction from the PDF produces clean words, not "S a i l i n g"
spaced out letter by letter. CI gate (macOS + Ubuntu) runs a combined-
features fixture through pdftotext on every PR.

make-pdf shells out to browse rather than duplicating Playwright.
$B pdf grew into a real PDF engine with full flag contract (--format,
--margins, --header-template, --footer-template, --page-numbers,
--tagged, --outline, --toc, --tab-id, --from-file). $B load-html and
$B js gained --tab-id. $B newtab --json returns structured output.

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

* docs(changelog): rewrite v1.4.0.0 headline — positive voice, no VC framing

The original headline led with "a PDF you wouldn't be embarrassed to send
to a VC": double-negative voice and audience-too-narrow. /make-pdf works
for essays, letters, memos, reports, proposals, and briefs. Framing the
whole release around founders-to-investors misses the wider audience.

New headline: "Turn any markdown file into a PDF that looks finished."
New tagline: "This one reads like a real essay or a real letter."

Positive voice. Broader aperture. Same energy.

Garry TanandClaude Opus 4.6 8ca950f6f1 feat: content security — 4-layer prompt injection defense for pair-agent (#815)
* feat: token registry for multi-agent browser access

Per-agent scoped tokens with read/write/admin/meta command categories,
domain glob restrictions, rate limiting, expiry, and revocation. Setup
key exchange for the /pair-agent ceremony (5-min one-time key → 24h
session token). Idempotent exchange handles tunnel drops. 39 tests.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: integrate token registry + scoped auth into browse server

Server changes for multi-agent browser access:
- /connect endpoint: setup key exchange for /pair-agent ceremony
- /token endpoint: root-only minting of scoped sub-tokens
- /token/:clientId DELETE: revoke agent tokens
- /agents endpoint: list connected agents (root-only)
- /health: strips root token when tunnel is active (P0 security fix)
- /command: scope/rate/domain checks via token registry before dispatch
- Idle timer skips shutdown when tunnel is active

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: ngrok tunnel integration + @ngrok/ngrok dependency

BROWSE_TUNNEL=1 env var starts an ngrok tunnel after Bun.serve().
Reads NGROK_AUTHTOKEN from env or ~/.gstack/ngrok.env. Reads
NGROK_DOMAIN for dedicated domain (stable URL). Updates state
file with tunnel URL. Feasibility spike confirmed: SDK works in
compiled Bun binary.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: tab isolation for multi-agent browser access

Add per-tab ownership tracking to BrowserManager. Scoped agents
must create their own tab via newtab before writing. Unowned tabs
(pre-existing, user-opened) are root-only for writes. Read access
always allowed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: tab enforcement + POST /pair endpoint + activity attribution

Server-side tab ownership check blocks scoped agents from writing to
unowned tabs. Special-case newtab records ownership for scoped tokens.
POST /pair endpoint creates setup keys for the pairing ceremony.
Activity events now include clientId for attribution.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: pair-agent CLI command + instruction block generator

One command to pair a remote agent: $B pair-agent. Creates a setup
key via POST /pair, prints a copy-pasteable instruction block with
curl commands. Smart tunnel fallback (tunnel URL > auto-start >
localhost). Flags: --for HOST, --local HOST, --admin, --client NAME.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: tab isolation + instruction block generator tests

14 tests covering tab ownership lifecycle (access checks, unowned
tabs, transferTab) and instruction block generator (scopes, URLs,
admin flag, troubleshooting section). Fix server-auth test that
used fragile sliceBetween boundaries broken by new endpoints.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: bump version and changelog (v0.15.9.0)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: CSO security fixes — token leak, domain bypass, input validation

1. Remove root token from /health endpoint entirely (CSO #1 CRITICAL).
   Origin header is spoofable. Extension reads from ~/.gstack/.auth.json.
2. Add domain check for newtab URL (CSO #5). Previously only goto was
   checked, allowing domain-restricted agents to bypass via newtab.
3. Validate scope values, rateLimit, expiresSeconds in createToken()
   (CSO #4). Rejects invalid scopes and negative values.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: /pair-agent skill — syntactic sugar for browser sharing

Users remember /pair-agent, not $B pair-agent. The skill walks through
agent selection (OpenClaw, Hermes, Codex, Cursor, generic), local vs
remote setup, tunnel configuration, and includes platform-specific
notes for each agent type. Wraps the CLI command with context.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: remote browser access reference for paired agents

Full API reference, snapshot→@ref pattern, scopes, tab isolation,
error codes, ngrok setup, and same-machine shortcuts. The instruction
block points here for deeper reading.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: improved instruction block with snapshot→@ref pattern

The paste-into-agent instruction block now teaches the snapshot→@ref
workflow (the most powerful browsing pattern), shows the server URL
prominently, and uses clearer formatting. Tests updated to match.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: smart ngrok detection + auto-tunnel in pair-agent

The pair-agent command now checks ngrok's native config (not just
~/.gstack/ngrok.env) and auto-starts the tunnel when ngrok is
available. The skill template walks users through ngrok install
and auth if not set up, instead of just printing a dead localhost
URL.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: on-demand tunnel start via POST /tunnel/start

pair-agent now auto-starts the ngrok tunnel without restarting the
server. New POST /tunnel/start endpoint reads authtoken from env,
~/.gstack/ngrok.env, or ngrok's native config. CLI detects ngrok
availability and calls the endpoint automatically. Zero manual steps
when ngrok is installed and authed.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: pair-agent skill must output the instruction block verbatim

Added CRITICAL instruction: the agent MUST output the full instruction
block so the user can copy it. Previously the agent could summarize
over it, leaving the user with nothing to paste.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: scoped tokens rejected on /command — auth gate ordering bug

The blanket validateAuth() gate (root-only) sat above the /command
endpoint, rejecting all scoped tokens with 401 before they reached
getTokenInfo(). Moved /command above the gate so both root and
scoped tokens are accepted. This was the bug Wintermute hit.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: pair-agent auto-launches headed mode before pairing

When pair-agent detects headless mode, it auto-switches to headed
(visible Chromium window) so the user can watch what the remote
agent does. Use --headless to skip this. Fixed compiled binary
path resolution (process.execPath, not process.argv[1] which is
virtual /$bunfs/ in Bun compiled binaries).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: comprehensive tests for auth ordering, tunnel, ngrok, headed mode

16 new tests covering:
- /command sits above blanket auth gate (Wintermute bug)
- /command uses getTokenInfo not validateAuth
- /tunnel/start requires root, checks native ngrok config, returns already_active
- /pair creates setup keys not session tokens
- Tab ownership checked before command dispatch
- Activity events include clientId
- Instruction block teaches snapshot→@ref pattern
- pair-agent auto-headed mode, process.execPath, --headless skip
- isNgrokAvailable checks all 3 sources (gstack env, env var, native config)
- handlePairAgent calls /tunnel/start not server restart

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: chain scope bypass + /health info leak when tunneled

1. Chain command now pre-validates ALL subcommand scopes before
   executing any. A read+meta token can no longer escalate to
   admin via chain (eval, js, cookies were dispatched without
   scope checks). tokenInfo flows through handleMetaCommand into
   the chain handler. Rejects entire chain if any subcommand fails.

2. /health strips sensitive fields (currentUrl, agent.currentMessage,
   session) when tunnel is active. Only operational metadata (status,
   mode, uptime, tabs) exposed to the internet. Previously anyone
   reaching the ngrok URL could surveil browsing activity.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: tout /pair-agent as headline feature in CHANGELOG + README

Lead with what it does for the user: type /pair-agent, paste into
your other agent, done. First time AI agents from different companies
can coordinate through a shared browser with real security boundaries.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs: expand /pair-agent, /design-shotgun, /design-html in README

Each skill gets a real narrative paragraph explaining the workflow,
not just a table cell. design-shotgun: visual exploration with taste
memory. design-html: production HTML with Pretext computed layout.
pair-agent: cross-vendor AI agent coordination through shared browser.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: split handleCommand into handleCommandInternal + HTTP wrapper

Chain subcommands now route through handleCommandInternal for full security
enforcement (scope, domain, tab ownership, rate limiting, content wrapping).
Adds recursion guard for nested chains, rate-limit exemption for chain
subcommands, and activity event suppression (1 event per chain, not per sub).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add content-security.ts with datamarking, envelope, and filter hooks

Four-layer prompt injection defense for pair-agent browser sharing:
- Datamarking: session-scoped watermark for text exfiltration detection
- Content envelope: trust boundary wrapping with ZWSP marker escaping
- Content filter hooks: extensible filter pipeline with warn/block modes
- Built-in URL blocklist: requestbin, pipedream, webhook.site, etc.

BROWSE_CONTENT_FILTER env var controls mode: off|warn|block (default: warn)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: centralize content wrapping in handleCommandInternal response path

Single wrapping location replaces fragmented per-handler wrapping:
- Scoped tokens: content filters + datamarking + enhanced envelope
- Root tokens: existing basic wrapping (backward compat)
- Chain subcommands exempt from top-level wrapping (wrapped individually)
- Adds 'attrs' to PAGE_CONTENT_COMMANDS (ARIA value exposure defense)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: hidden element stripping for scoped token text extraction

Detects CSS-hidden elements (opacity, font-size, off-screen, same-color,
clip-path) and ARIA label injection patterns. Marks elements with
data-gstack-hidden, extracts text from a clean clone (no DOM mutation),
then removes markers. Only active for scoped tokens on text command.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: snapshot split output format for scoped tokens

Scoped tokens get a split snapshot: trusted @refs section (for click/fill)
separated from untrusted web content in an envelope. Ref names truncated
to 50 chars in trusted section. Root tokens unchanged (backward compat).
Resume command also uses split format for scoped tokens.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add SECURITY section to pair-agent instruction block

Instructs remote agents to treat content inside untrusted envelopes
as potentially malicious. Lists common injection phrases to watch for.
Directs agents to only use @refs from the trusted INTERACTIVE ELEMENTS
section, not from page content.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: add 4 prompt injection test fixtures

- injection-visible.html: visible injection in product review text
- injection-hidden.html: 7 CSS hiding techniques + ARIA injection + false positive
- injection-social.html: social engineering in legitimate-looking content
- injection-combined.html: all attack types + envelope escape attempt

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* test: comprehensive content security tests (47 tests)

Covers all 4 defense layers:
- Datamarking: marker format, session consistency, text-only application
- Content envelope: wrapping, ZWSP marker escaping, filter warnings
- Content filter hooks: URL blocklist, custom filters, warn/block modes
- Instruction block: SECURITY section content, ordering, generation
- Centralized wrapping: source-level verification of integration
- Chain security: recursion guard, rate-limit exemption, activity suppression
- Hidden element stripping: 7 CSS techniques, ARIA injection, false positives
- Snapshot split format: scoped vs root output, resume integration

Also fixes: visibility:hidden detection, case-insensitive ARIA pattern matching.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: pair-agent skill compliance + fix all 16 pre-existing test failures

Root cause: pair-agent was added without completing the gen-skill-docs
compliance checklist. All 16 failures traced back to this.

Fixes:
- Sync package.json version to VERSION (0.15.9.0)
- Add "(gstack)" to pair-agent description for discoverability
- Add pair-agent to Codex path exception (legitimately documents ~/.codex/)
- Add CLI_COMMANDS (status, pair-agent, tunnel) to skill parser allowlist
- Regenerate SKILL.md for all hosts (claude, codex, factory, kiro, etc.)
- Update golden file baselines for ship skill
- Fix relink tests: pass GSTACK_INSTALL_DIR to auto-relink calls so they

* chore: bump version and changelog (v0.15.12.0)

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix: E2E exit reason precedence + worktree prune race condition

Two fixes for E2E test reliability:

1. session-runner.ts: error_max_turns was misclassified as error_api
   because is_error flag was checked before subtype. Now known subtypes
   like error_max_turns are preserved even when is_error is set. The
   is_error override only applies when subtype=success (API failure).

2. worktree.ts: pruneStale() now skips worktrees < 1 hour old to avoid
   deleting worktrees from concurrent test runs still in progress.
   Previously any second test execution would kill the first's worktrees.

* fix: restore token in /health for localhost extension auth

The CSO security fix stripped the token from /health to prevent leaking
when tunneled. But the extension needs it to authenticate on localhost.
Now returns token only when not tunneled (safe: localhost-only path).

* test: verify /health token is localhost-only, never served through tunnel

Updated tests to match the restored token behavior:
- Test 1: token assignment exists AND is inside the !tunnelActive guard
- Test 1b: tunnel branch (else block) does not contain AUTH_TOKEN

* docs: add security rationale for token in /health on localhost

Explains why this is an accepted risk (no escalation over file-based
token access), CORS protection, and tunnel guard. Prevents future
CSO scans from stripping it without providing an alternative auth path.

* fix: verify tunnel is alive before returning URL to pair-agent

Root cause: when ngrok dies externally (pkill, crash, timeout), the server
still reports tunnelActive=true with a dead URL. pair-agent prints an
instruction block pointing at a dead tunnel. The remote agent gets
"endpoint offline" and the user has to manually restart everything.

Three-layer fix:
- Server /pair endpoint: probes tunnel URL before returning it. If dead,
  resets tunnelActive/tunnelUrl and returns null (triggers CLI restart).
- Server /tunnel/start: probes cached tunnel before returning already_active.
  If dead, falls through to restart ngrok automatically.
- CLI pair-agent: double-checks tunnel URL from server before printing
  instruction block. Falls through to auto-start on failure.

4 regression tests verify all three probe points + CLI verification.

* feat: add POST /batch endpoint for multi-command batching

Remote agents controlling GStack Browser through a tunnel pay 2-5s of
latency per HTTP round-trip. A typical "navigate and read" takes 4
sequential commands = 10-20 seconds. The /batch endpoint collapses N
commands into a single HTTP round-trip, cutting a 20-tab crawl from
~60s to ~5s.

Sequential execution through the full security pipeline (scope, domain,
tab ownership, content wrapping). Rate limiting counts the batch as 1
request. Activity events emitted at batch level, not per-command.
Max 50 commands per batch. Nested batches rejected.

* test: add source-level security tests for /batch endpoint

8 tests verifying: auth gate placement, scoped token support, max
command limit, nested batch rejection, rate limiting bypass, batch-level
activity events, command field validation, and tabId passthrough.

* refactor: consolidate Hermes into generic HTTP option in pair-agent

Hermes doesn't have a host-specific config — it uses the same generic
curl instructions as any other agent. Removing the dedicated option
simplifies the menu and eliminates a misleading distinction.

* chore: bump VERSION to 0.15.14.0, add CHANGELOG entry for batch endpoint

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* chore: regenerate pair-agent/SKILL.md after main merge

Vendoring deprecation section from main's template wasn't reflected
in the generated file. Fixes check-freshness CI.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* refactor: checkTabAccess uses options object, add own-only tab policy

Refactors checkTabAccess(tabId, clientId, isWrite) to use an options
object { isWrite?, ownOnly? }. Adds tabPolicy === 'own-only' support
in the server command dispatch — scoped tokens with this policy are
restricted to their own tabs for all commands, not just writes.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* feat: add --domain flag to pair-agent CLI for domain restrictions

Allows passing --domain to pair-agent to restrict the remote agent's
navigation to specific domains (comma-separated).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* revert: remove batch commands CHANGELOG entry and VERSION bump

The batch endpoint work belongs on the browser-batch-multitab branch
(port-louis), not this branch. Reverting VERSION to 0.15.14.0.

* fix: adopt main's headed-mode /health token serving

Our merge kept the old !tunnelActive guard which conflicted with
main's security-audit-r2 tests that require no currentUrl/currentMessage
in /health. Adopts main's approach: serve token conditionally based on
headed mode or chrome-extension origin. Updates server-auth tests.

* fix: improve snapshot flags docs completeness for LLM judge

Adds $B placeholder explanation, explicit syntax line, and detailed
flag behavior (-d depth values, -s CSS selector syntax, -D unified
diff format and baseline persistence, -a screenshot vs text output
relationship). Fixes snapshot flags reference LLM eval scoring
completeness < 4.

cd66fc2f89 fix: 6 critical fixes + community PR guardrails (v0.13.2.0) (#602)
* fix(security): commit bun.lock to pin dependency versions

Remove bun.lock from .gitignore and commit the lockfile. Every bun install
now uses exact pinned versions instead of resolving floating ^ ranges from
npm fresh. Closes the supply-chain vector from #566.

* fix: gstack-slug falls back to dirname/unknown when git context is absent

Add || true to git commands and fallback defaults so gstack-slug works
outside git repos. Prevents unbound variable crash that kills every
review skill when no git context exists.

* fix: setup auto-selects default after 10s timeout to prevent CI hangs

Add -t 10 to the read command in the skill-prefix prompt. In CI, Docker,
and Conductor workspaces where a TTY exists but nobody is watching, the
prompt now auto-selects short names after 10 seconds instead of blocking
forever.

* fix: browse CLI Windows lockfile — use string flag instead of numeric constants

Bun compiled binaries on Windows don't handle numeric fs.constants
correctly. The string flag 'wx' is semantically identical to
O_CREAT | O_EXCL | O_WRONLY per Node docs and works on all platforms.

* fix: add ~/.gstack/projects/ to plan file search path

/office-hours writes design docs to ~/.gstack/projects/$SLUG/ but /ship
and /review only searched ~/.claude/plans, ~/.codex/plans, and .gstack/plans.
Add the project-scoped directory as the first search location so plan
validation finds design docs created by the standard workflow.

Fixes #591

* fix: autoplan dual-voice — sequential foreground execution instead of broken parallel

Background subagents don't inherit tool permissions in Claude Code, so the
Claude subagent in dual-voice mode was silently failing on every invocation.
Every autoplan run was degrading to single-reviewer mode without warning.

Change all three phases (CEO, Design, Eng) from "simultaneously" to
sequential foreground execution: Claude subagent first (Agent tool,
foreground), then Codex (Bash). Both complete before the consensus table.

Fixes #497

scripts/resolvers/review.ts (plan search path fix).

* docs: add community PR guardrails — protect ETHOS.md and voice

Add explicit CLAUDE.md rule requiring AskUserQuestion before accepting
any community PR that touches ETHOS.md, removes promotional material,
or changes Garry's voice. No exceptions, no auto-merging.

* chore: bump version and changelog (v0.13.2.0)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix: gen-skill-docs detects symlink loop, skips codex write that overwrites Claude SKILL.md

When .agents/skills/gstack is symlinked to the repo root (vendored dev mode),
gen-skill-docs --host codex was writing the Codex-transformed SKILL.md through
the symlink, overwriting the Claude version. This caused SKILL.md and
agents/openai.yaml to silently revert to Codex paths after every build.

Now detects when the codex output path resolves to the same real file as the
Claude output and skips the write. Content is still generated for token budget
tracking. The openai.yaml write is also skipped for the same symlink case.

* fix: resolve all 7 test failures — version sync, zsh glob guard, symlink-aware codex tests

1. package.json version synced with VERSION file (0.13.3.0)
2. design-shotgun/SKILL.md.tmpl: added setopt +o nomatch guard to
   bash block with variant-*.png glob
3. Codex generation tests: skip skills where .agents/skills/{name}
   is a symlink back to repo root (vendored dev mode). These can't
   have proper codex content since gen-skill-docs skips the write
   to avoid overwriting the Claude SKILL.md.
