+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.

Port range 10000-49151 + busy-vs-dead daemon semantics + XProtect launch
heal + browse-daemon.log in BROWSER.md/ARCHITECTURE.md; #2557 dead security
surface (shield, L4b Haiku, DeBERTa ensemble, canary injector) marked

* 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.

Garry TanandClaude Fable 5 c118e2402e v1.64.1.0 v1.64.1.0: the code-smell fix wave — every pipeline guard now provably fires (net −24,943 lines) (#2572)
* fix(ci): skill-docs freshness gate covers all 10 hosts and can actually fail

The Codex/Factory gates ran 'git diff --exit-code -- .agents/' / '-- .factory/',
but both paths are gitignored (.gitignore:16-17) — git diff on ignored untracked
paths is always empty, so those two gates were structurally incapable of failing
and 7 of 10 hosts had no gate at all.

New shape: one 'gen:skill-docs --host all' pass (the generator hard-fails on any
per-host error, gating all 10 hosts on generates-cleanly), byte-freshness via
git diff for tracked output, plus a porcelain check that fails on untracked
generated strays (git diff can't see brand-new files). The gitignored-hosts
byte-freshness limitation is documented in the workflow comment.

* fix(test): exorcise the sidebar-agent ghost from the test suite

browse/src/sidebar-agent.ts was deleted in the v1.14 sidebar refactor, but the
test suite kept testing it for 48 versions. Nothing noticed because the free
suite runs in no CI job and Bun-era module-load errors were suppressed in the
Windows shard runner via an exclusion pattern whose own comment documented the
breakage ('broken on every platform since v1.14 ... exit 0').

- Delete sidebar-security.test.ts + security-source-contracts.test.ts: crashed
  at module load (unguarded readFileSync of the deleted file); per-assertion
  triage confirmed every SERVER_SRC pin targeted the deleted chat prompt
  builder (zero hits in today's server.ts) — nothing to port.
- Delete sidebar-integration.test.ts: 11 of 13 tests exercised deleted
  endpoints (/sidebar-command queue, /sidebar-agent/event, chat buffer); the 2
  passing tests pinned only the blanket auth gate, covered by
  server-auth.test.ts + dual-listener.test.ts.
- Delete test/skill-e2e-sidebar.test.ts: E2E for the deleted queue flow.
- sidebar-ux.test.ts 1,669 -> 830 lines: 20 dead-chat describes + 15 dead
  tests removed (incl. 10 vacuous passes asserting on empty indexOf slices);
  2 stale pins on LIVE features fixed (content.js typed-catch CSSOM fallback,
  arrow-hint window widened). 95 pass / 0 fail.
- sidebar-tabs.test.ts: both failures were stale pins, not regressions —
  forceRestart's deliberate ws.close(4001) and the terminal-agent spawn that
  moved into spawnTerminalAgent() (identity-based kill refactor). 28 pass.
- touchfiles.ts: drop the three sidebar E2E entries from BOTH maps
  (E2E_TOUCHFILES + E2E_TIERS) — they pointed diff-selection at the deleted
  file, so those tests were unreachable by any diff.
- test-free-shards.ts: remove the now-dead sidebar-agent exclusion pattern.

* feat(ci): run the free test suite in CI (it ran nowhere)

The full free suite (bun test: browse/test/ + test/ + make-pdf/test/) had no CI
job on any Linux/macOS runner — only Windows curated shards, paid evals, and
doc-freshness gates existed. That's how two module-load-crashing test files
survived 48 versions.

Same cached Dockerfile.ci image and container wiring as evals.yml (deps
restore, build, Chromium verify). Includes a module-load-error guard: older
Bun reported test-file import crashes with exit 0 on macOS/Linux, so the job
also fails on any nonzero 'N errors' count in the summary — future crash-class
regressions can't hide from the exact job built to catch them.

* feat(test): validate touchfile dependency paths exist on disk

New guard in touchfiles.test.ts: every non-glob dep path must exist, and every
glob's anchor directory must exist. This is the axis the 181-key two-map sync
discipline never covered — an entry can point at a long-deleted file and
diff-based selection then silently never triggers those tests (the sidebar
trio sat rotted for 48 versions).

First run immediately caught a fourth rotted entry: 'spec authored quality'
referenced test/fixtures/spec/** (directory does not exist) and selected for a
judge test that exists nowhere in the repo. Removed.

* fix(security): remove deleted /sidebar-chat endpoint from tunnel allowlist

TUNNEL_PATHS is the audited tunnel attack surface — its own comment says every
addition widens it. '/sidebar-chat' stayed in the set after the endpoint was
deleted with the chat-queue path, meaning any future route matching that path
would have been silently tunnel-exposed. The set is now exactly the pair
ceremony (/connect) and the scoped command endpoint (/command), and the
dual-listener closed-set pin enforces that.

Also repairs a pre-existing red pin in dual-listener.test.ts: v1.63.0.0 made
the tunnel allowlist args-aware (canDispatchOverTunnel gained a second param)
without updating the test — red on main since then, invisible because the free
suite had no CI job.

* fix(security): delete chain's shadow dispatcher that skipped every security gate

meta-commands.ts carried a 'CLI mode' fallback that re-implemented command
routing without the server pipeline's gates: no scope check, no domain check,
no tab ownership, no rate limit, no hidden-element stripping, no scoped-token
enveloping — and it called handleReadCommand without a BrowserManager, which
also skipped the JS-origin cookie-exfiltration assertion. It was unreachable
in production (server.ts always passes executeCommand) and one boolean away
from being live.

chain now hard-errors without a server context. handleReadCommand's bm param
is required and assertJsOriginAllowed runs unconditionally. The chain tests
that exercised the deleted fallback now route through a server-shaped
executeCommand adapter (real handlers + trust wrapping + {status,result}
envelope), so their behavioral coverage — sequencing, trust markers, pipe
format, aliases, error reporting — survives on the production-shaped path.

* fix(extension): delete the dead chat-queue client surface

The sidebar-command handler in background.js POSTed to a server endpoint that
no longer exists (deleted with the chat queue) — ~35 lines of fully-wired dead
code including error handling for the permanent 404, plus its allowlist entry.
No sender in the extension ever emitted the message type.

chatEnabled leaves the /health contract (server hardcoded false, background.js
re-derived it, nothing consumed it — the chat input element it guarded is gone
from sidepanel.html). BROWSE_SIDEBAR_CHAT env flag had zero readers.

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

* fix(security): delete dead exports the ripped chat path left behind

Three-way split by importer class:

(a) Zero importers, deleted: the whole attack-attempt logging cluster in
security.ts (logAttempt, AttemptRecord, salted hashPayload + device-salt,
attempts.jsonl rotation, telemetry spawn plumbing incl.
buildTelemetrySpawnCommand/resolveBashBinary — the LIVE attempts.jsonl writer
is tunnel-denial-log.ts with its own rotation); the decision-file handshake
(writeDecision/readDecision/clearDecision/excerptForReview — written for
sidebar-agent's poll loop, which no longer exists); sidebar-utils.ts (whole
module — its sanitizeExtensionUrl 'sanitized before embedding in a prompt'
for the deleted prompt builder); 8 dead server.ts imports (sanitizeExtensionUrl,
generateCanary, injectCanary, writeDecision, rotateRoot, serializeRegistry,
restoreRegistry, clearAgentRecord); buildPtyClearCookie + buildSseClearCookie;
WEBDRIVER_MASK_SCRIPT (orphaned by the D7 stealth narrowing — applyStealth
never used it).

(b) Dead-pin tests edited with their exports: the 'still exported' pin in
stealth-layer-c, the string-content describe in stealth-webdriver (its live
applyStealth behavioral coverage untouched), the clear-cookie assertions,
security-review-flow.test.ts deleted whole (all 4 describes exercised the
dead decision mechanism, incl. a 'simulated sidebar-agent poll loop').

(c) KEPT deliberately: leaseCount (live behavioral coverage),
extractPtyCookie + validatePtySessionToken (extractPtyCookie is adopted by
the terminal-agent cookie-parse unification later in this wave),
resetSessionMarker + clearContentFilters (test-support API for the live
content-security layer).

Also fixes two pre-existing red pins found while here, invisible until the
free suite got a CI job: the v1.44 spawnClaude->maybeSpawnPty rename in
terminal-agent.test.ts, and a cross-file test-isolation bug where
content-security.test.ts's clearContentFilters() wiped the auto-registered
url-blocklist filter for every later file in the same bun process
(security-integration.test.ts failed on co-run; afterAll now restores it).

* fix(security): delete the dead ML layers — transcript classifier and DeBERTa ensemble

The L4b Haiku transcript classifier and the opt-in DeBERTa ensemble
(GSTACK_SECURITY_ENSEMBLE=deberta, a documented 721MB download) had ZERO
production callers since the chat-path agent that invoked them was ripped.
The only live ML path is scanPageContent (testsavant) inside the security
sidecar subprocess. Deleted by import graph:

- security-classifier.ts 614 -> 265 lines: HAIKU_MODEL, checkTranscript,
  shouldRunTranscriptCheck, loadDeberta, scanPageContentDeberta, ToolCallInput,
  all DEBERTA_* consts + load state. Header now states the live truth
  (imported only by security-sidecar-entry.ts). downloadFile kept, name
  intact — it is an enumerated egress sink (HF model download).
- security-bunnative.ts + test: a research skeleton self-described as 'NOT a
  production replacement', shipped into src/ with zero importers.
- security-bench-ensemble{,-live}.test.ts + the Haiku response fixture: a
  paid live-model benchmark for a layer that could not fire. The
  security-classifier-tdz test's only case exercised checkTranscript — gone.
- security.ts: layer-model header rewritten to the live architecture;
  StatusDetail.layers -> {testsavant, canary}; getStatus() no longer requires
  the impossible transcript==='ok' for 'protected' (old on-disk session state
  with a transcript key is tolerated on read, never re-emitted).
- security-sidecar-entry.ts needed zero changes: it serializes
  getClassifierStatus() verbatim and no consumer read .transcript (verified
  in sidecar-client + server.ts).
- BROWSER.md security section matches reality (ensemble knob gone, 112MB not
  22MB, sidecar hosting documented). combineVerdict/THRESHOLDS retained as
  the pure, tested combiner of record — comments now flag transcript/deberta
  votes as producer-less.

Net: 26 pass in security.test.ts incl. a NEW regression test for stale-
transcript disk tolerance; egress-receipt tripwire green.

* docs: scrub the sidebar-agent ghost from comments and CLAUDE.md

20+ comments across 10 files still described the deleted sidebar-agent.ts as a
live process — including load-bearing architecture claims ('IMPORTED ONLY BY
sidebar-agent.ts', 'sidebar-agent fills this in on first prompt-injection
load', 'kill sidebar-agent' in shutdown docs) and ~60 lines of tombstone
blocks in server.ts enumerating deleted identifiers by name (a false grep
surface: searching processAgentEvent hit server.ts and looked live).

CLAUDE.md's security-stack section now documents the LIVE architecture: L1-L3
content filters + testsavant via the security sidecar subprocess; the
L4b/ensemble rows, the GSTACK_SECURITY_ENSEMBLE knob, and the 721MB DeBERTa
download are gone (deleted as dead code this wave) with an explicit
do-not-re-document note; attempts.jsonl is correctly attributed to
tunnel-denial-log.ts; the no-live-writer status of classifierStatus is stated.

Comments that survive now describe what IS, not what WAS: the promotion gate
in domain-skills.ts explains why classifier_score>0 is load-bearing given no
L4 load-time scan exists; file-permissions.ts names real sensitive files.

* fix(gen): delete the codex-helpers shadow module

gen-skill-docs.ts imported externalSkillName (unaliased) from
resolvers/codex-helpers.ts at line 21 and then re-declared the same function
locally — the import was silently shadowed, and the imported copy was the
STALE one (it lacked the frontmatterName param the local copy grew). Three
more functions were byte-identical duplicates, imported only under _-prefixed
aliases to keep the module 'referenced', and transformFrontmatter was a
superseded hardcoded-Codex variant. Nothing else imported the module.

Also drops three dead top-of-file imports (COMMAND_DESCRIPTIONS,
SNAPSHOT_FLAGS — which pulled the whole browse/src module graph into every
generator run for nothing — and an unused review-resolver trio).

Proof: bun run gen:skill-docs exits 0 with a byte-identical tree (zero-diff
regen); gen-skill-docs.test.ts 405/405 green.

* fix(server): delete ServerConfig.idleTimeoutMs + chromiumProfile — documented, never read

Both fields carried JSDoc asserting embedder behavior that did not exist:
the idle check reads the module-level IDLE_TIMEOUT_MS env constant, and both
resolveChromiumProfile() call sites pass no argument. Worse than absent — an
embedder passing idleTimeoutMs: 5000 silently got 30 minutes.

Wiring them honestly is impossible today: the idle timer, activity state, and
shutdown target are module-global, so a per-factory value would lie for any
process running more than one handler. Deleted instead, with a ServerConfig
note pointing at the deferred singleton/route-table refactor where real
support belongs. BROWSE_IDLE_TIMEOUT and CHROMIUM_PROFILE env remain the
honest knobs.

* fix(security): wire appendSecureFile at the four real log-append sites

file-permissions.ts carries a 24-line rationale for why POSIX mode bits are
insufficient on Windows and implements appendSecureFile (0600 at create,
Windows ACL on first write only) — but its single caller was the dead
logAttempt, while the four REAL page-content log writers (console/network/
dialog logs in server.ts, the command audit log) used raw fs.appendFileSync
with no mode. Page-content-derived logs now get owner-only permissions from
birth on every platform.

Verified before wiring: mode applies atomically at create via appendFileSync
{mode}, and the ACL pass runs only on first write — no per-append subprocess
cost on the hot console-log path.

* fix(stealth): handoff() uses the shared profile resolution + lock cleanup

The headless-to-headed handoff path hardcoded ~/.gstack/chromium-profile,
silently ignoring $CHROMIUM_PROFILE and $GSTACK_HOME (gbrowser's gbd sets
per-workspace profiles), and skipped cleanSingletonLocks() — so a handoff
into a profile with a stale SingletonLock could hang where launchHeaded()
would have recovered.

This was the third live drift between the three Chromium launch paths; the
first two are documented in comments as shipped stealth regressions. Minimal
targeted fix — the full buildLaunchConfig() extraction stays in the deferred
queue.

* fix(gen): resolver registry describes the template language again

Seven registered {{PLACEHOLDER}}s had zero uses in any .tmpl (checked in both
bare and :arg forms): REDACT_TAXONOMY_TABLE, TEST_COVERAGE_AUDIT_REVIEW,
MODEL_OVERLAY, QUESTION_PREFERENCE_CHECK, QUESTION_LOG, INLINE_TUNE_FEEDBACK,
MAKE_PDF_SETUP. The last two of those families are invoked programmatically by
preamble.ts (functions kept, registry entries dropped); the question-tuning
trio and the review coverage-audit wrapper were documented by their own module
as existing 'for unit testing' that no test performed — deleted, along with
generateRedactTaxonomyTable + its EXAMPLE/TIER_BLURB constants (its '/cso
renders the full table' comment was itself stale) and its test describe.

Also deletes the gated-resolver mechanism (ResolverEntry/appliesTo/
unwrapResolver + test/resolver-entry.test.ts): fully built, fully tested,
used by zero of the 65 registry entries — the generator loop simplifies to a
direct function call. CLAUDE.md's redact-doc line stops advertising the dead
token.

Proof: zero-diff regen (0 SKILL.md changed); gen-skill-docs + skill-validation
737 tests green.

* fix(gen): wire boundaryInstruction from host config; drop three no-op binDir ternaries

hosts/codex.ts declared boundaryInstruction and nothing read it — review.ts
kept its own byte-identical CODEX_BOUNDARY literal (verified equal + trailing
escaped newlines). The resolver now reads the config, so the boundary has one
owner. (autoplan's template carries deliberately generic variants, enforced by
gen-skill-docs.test.ts:1358 — untouched by design.)

The 'ctx.host === codex ? $GSTACK_BIN : ctx.paths.binDir' ternary appeared in
three resolvers and could never change the result: resolvers/types.ts already
sets binDir to $GSTACK_BIN for every usesEnvVars host including codex.

Proof: zero-diff regen for claude AND codex hosts; gen-skill-docs +
host-config suites green.

* fix(test-infra): judge uses resolveClaudeBinary; eval:watch reads the real partials dir

judgePtyState spawned the bare string 'claude' three definitions below the
resolveClaudeBinary() helper this same file exports — broken under hermetic
PATHs where every other launch in the file resolves correctly.

eval:watch read _partial-e2e.json from the legacy global ~/.gstack-dev/evals/
while EvalCollector writes it into the per-project eval dir (or
GSTACK_EVAL_DIR) — so the dashboard's completed-tests panel was empty
whenever slug detection succeeded, i.e. the normal case. The heartbeat and
per-run progress logs stay global by design (session-runner.ts: 'heartbeat
stays global'). The three eval-CLI docstrings stop claiming the legacy dir
is the primary location.

* fix(test): delete the superseded SDK ship-idempotency suite and three orphaned fixtures

test/skill-e2e-ship-idempotency.test.ts's own header documented that the
monolith's SDK-harness version tests a synthetic prompt while it exercises
the real /ship skill — the author knew the old suite was superseded and left
both running, two paid LLM runs for one behavior. The weaker copy is gone;
its 'ship-idempotency' diff-selection key goes with it (the dedicated file is
periodic-tier, which always runs under EVALS_ALL — the key had no remaining
consumer).

Fixture rot: test/fixtures/golden-ship-claude.md was a 128KB zero-reader
orphan that had drifted 46KB from its live successor
(test/fixtures/golden/claude-ship-SKILL.md) while looking authoritative;
parity-baseline-v1.46.0.0.json and v1.53.0.0.json had zero readers (three
tests pin three OTHER baseline versions — consolidation is queued, deletion
of the unreferenced two is free).

* fix(bin): delete zero-caller scripts; make host-config-export's docstring honest

- bin/gstack-open-url (14 lines): announced in a CHANGELOG entry, wired into
  nothing, ever. bin/gstack-platform-detect (27 lines): zero callers, and its
  hand-rolled host list was already stale (SLATE_HOST.md cites it as a
  problem). Note: the deprecated gstack-brain-consumer/reader pair the audit
  flagged was already deleted upstream in v1.63 with a stay-deleted tripwire.
- scripts/task-emission-schema.ts (61 lines): a typed schema module nothing
  imported; the tasks-section comment now documents the JSONL fields inline.
- scripts/host-config-export.ts claimed to be the 'shell bridge for the bash
  setup script' — setup never calls it (its hand-rolled host lists drifting
  is a known follow-up). Docstring now states what it IS: a standalone,
  test-pinned query CLI not yet wired into setup. Its validateValue +
  CLI_REGEX/PATH_REGEX internals were dead (defined for a guarantee the
  header claimed but nothing enforced).
- KEPT deliberately: scripts/preflight-agent-sdk.ts — a documented manual
  diagnostic (CONTRIBUTING.md + USING_GBRAIN_WITH_GSTACK.md reference it).

* fix(server): one lone-surrogate sanitizer, one sanitizeReplacer, one startTunnel

Three copies of the surrogate sanitizer existed with two algorithms
(sanitize.ts regex vs a hand-rolled charCodeAt walk in server.ts — verified
byte-identical across 11 edge cases before converging) plus two identical
sanitizeReplacer definitions each wrapping a different copy. sanitize.ts is
now the single source of truth; the runs-INSIDE-JSON.stringify egress
invariant is unchanged at every call site and its pin tests were adapted to
the new import shape without losing intent.

The ngrok tunnel-start sequence existed three times in server.ts — the
/tunnel/start route and the BROWSE_TUNNEL=1 autostart were line-for-line
equivalent (a comment admitted 'Same cleanup as /tunnel/start's error path').
One startTunnel() now owns the ephemeral loopback bind, the pre-send egress
receipt, the state-file RMW via tmpStatePath(), and the ordered error-path
cleanup; callers keep their distinct response surfaces. The
BROWSE_TUNNEL_LOCAL_ONLY test path shares nothing (no ngrok, different state
field) and deliberately stays separate.

* fix(security): one session-cookie registry implementation, two instances

pty-session-cookie.ts and sse-session-cookie.ts were byte-identical modulo
the cookie name — mint/validate/parse/prune/TTL, the exact code a security
fix would have to land in twice (and a third hand-rolled cookie parse in
terminal-agent.ts had already diverged; unified next commit).
createSessionCookieStore() owns the implementation; both modules become thin
instantiations keeping every exported name, their distinct threat-model
docstrings, and separate token spaces (an SSE-read cookie must never grant
PTY access). pty-session-lease.ts deliberately stays out — different contract
(sessionId/secret split, refresh, env TTL).

The factory imports nothing from token-registry (cookie-picker-auth-isolation
invariant, still pinned by sse-session-cookie.test.ts).

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

* fix(security): terminal-agent uses the shared PTY cookie parser

The /ws upgrade's cookie fallback hand-parsed the Cookie header inline — the
fourth copy of the session-cookie parse, and the one that had already
diverged from the others. Parsing now goes through extractPtyCookie;
validation deliberately stays against the agent's own in-process validTokens
map (the server's registry lives in a different process). The ws-handler pin
test now pins the shared-parser call instead of the raw cookie-name literal.

* refactor(hosts): defineHost() factory — 10 copy-paste host files become declarations

hosts/*.ts were ten copies of one file: runtimeRoot byte-identical in 9/10,
pathRewrites mechanically derivable from the host name for 7/10, the 11-entry
toolRewrites map byte-identical between openclaw and gbrain, and every asset
change a 10-file edit (cursor and slate had already fallen out of three other
hand-maintained lists). defineHost() owns the defaults; each host file now
declares only what makes it different (slate/cursor: 8 lines each). Shared
constants: CROSS_MODEL_RESOLVERS, GBRAIN_RESOLVERS, EXEC_STYLE_TOOL_REWRITES.
Genuinely-different things stayed explicit: codex/factory $GSTACK_ROOT
rewrites, hermes's tool vocabulary, claude's denylist+prefixable install,
opencode's wider runtimeRoot.

Proof: JSON.stringify(ALL_HOST_CONFIGS) dump-diff before/after EMPTY (and a
runtime walk confirmed no function-valued or undefined-keyed fields, so the
JSON diff is complete); gen:skill-docs --host all zero-diff; host-config +
gen-skill-docs + idempotency suites 485/485. Host files 595 -> 285 lines.
docs/ADDING_A_HOST.md teaches the factory pattern.

* feat(lib): fs-atomic — one atomic-write implementation, with the race actually fixed

Atomic tmp-write-then-rename was reimplemented ~20 times across lib/, bin/,
and browse/src with three tmp-suffix conventions. One of them was a latent
bug this commit closes: lib/worktree.ts used a bare '.tmp' suffix — the
deterministic-tmp collision race browse/src/server.ts documents having hit
in production (its fix, pid+random, was trapped in a comment at one site).

lib/fs-atomic.ts: atomicWriteSync (always throws, best-effort tmp cleanup,
pid+random suffix, optional mode applied at tmp creation so the file never
exists with looser permissions) + atomicWriteQuiet (shutdown paths only).
Unit tests pin the throw/quiet contracts, 0600 mode, tmp-name uniqueness
(captured via the read-only-dir failure path — Bun's fs exports are
readonly, no monkeypatching), and no-stray-tmp cleanup.

Migrated: lib/worktree.ts (the bare-.tmp bug), lib/gstack-decision.ts
(snapshot + compact log), lib/gbrain-local-status.ts (probe cache). browse
sites follow separately.

* fix(lib): jsonl-store's docstring stops lying; mode option added; lib bypasses adopted

The header claimed 'single source of truth... the ONLY copy' with write-time
injection REJECTION — while appendJsonl never screened anything, only 1 of
~10 JSONL stores imported it, and a bypass appender lived in the same
directory. Now: the contract is explicit (screening is the CALLER's job via
hasInjection/firstInjectionMatch; the enforcing callers are named), a
option applies 0600 at create for sensitive stores, and the lib bypasses are
adopted (gstack-memory-helpers ×2, redact-audit-log — which keeps its chmod
backstop for files created looser by pre-mode versions). browse/src keeps
its own appenders by design (compiled-binary surface, own secure-append
helper) and the header now says so. gstack-decision's batched archive append
stays deliberate (single-write crash-window semantics appendJsonl's
one-record contract can't express).

New pins: 0600-at-create, and a test that documents appendJsonl does NOT
self-screen — so nobody can re-document it as self-screening without making
it true.

* fix(browse): migrate hand-rolled atomic writes to lib/fs-atomic

Seven sites, each audited for its existing throw-vs-swallow contract before
migrating: writeSessionState + the four fire-and-forget tab/state writers use
atomicWriteQuiet (they swallowed before); writeAgentRecord + the boot-time
port-file write use atomicWriteSync (they threw before — and writeAgentRecord
previously leaked its tmp file on rename failure, which the helper cleans).
All carry {mode: 0o600} plus restrictFilePermissions after successful writes,
preserving the Windows ACL hardening that writeSecureFile provided (mode bits
are POSIX-only). server.ts untouched: its three state writes route through
tmpStatePath(), pinned by server-tmp-state-path.test.ts.

* fix(hosts): delete five dead HostConfig fields

metadataFormat (generator hardcodes openai.yaml), sidecar (behavior lives in
setup's create_agents_sidecar — knowledge preserved as a comment in codex.ts),
install.prefixable (skill_prefix is implemented entirely in bin/gstack-config),
staticFiles (docstring cited a SOUL.md that never existed anywhere), and
adapter (its only would-be consumer, openclaw-adapter.ts, was fully dead —
with a test asserting the field was undefined). Kept: learningsMode (wired
next), linkingStrategy (validation reads it), coAuthorTrailer (consumed by
resolvers/utility.ts).

Proof: JSON dump diff shows ONLY the deleted keys vanishing; zero-diff regen
across all 10 hosts; host-config + gen-skill-docs suites green. Note: this
commit also carries chunk-23 edits to the shared hosts/claude.ts +
define-host.ts + host-config.test.ts files (skipSkills collapse, stale
line-number comment drops) — pathspec commits, concurrent prep.

* fix(gen): preamble tiers are explicit; silent ?? 4 default becomes an error; spec stops rendering its preamble twice

Eight skills (scrape, diagram, spec, skillify, pair-agent, landing-report,
open-gstack-browser + its connect-chrome symlink) silently received the
HEAVIEST tier-4 preamble because a missing frontmatter field defaulted to 4.
Tiers are now declared in every {{PREAMBLE}} template's frontmatter and a
missing declaration throws at generation time with the template path (the 5
templates without {{PREAMBLE}} never invoke the resolver). The stale
hand-written tier-map comment (wrong in 3 of 4 rows) is gone.

Bonus bug fixed: spec/SKILL.md.tmpl mentioned {{PREAMBLE}} in prose, so the
generator inlined the ENTIRE preamble a second time — spec/SKILL.md shrinks
127,462 -> 80,924 bytes (-46,538) from de-duplication alone. skill-size-budget
gains a reasoned INTENTIONAL_SHRINKS entry (its frozen baseline had measured
the doubled-preamble bug). New tests: missing-tier throw carries the path;
every {{PREAMBLE}} template declares a tier. (Carries chunk-23 edits in the
shared test/gen-skill-docs.test.ts.)

* fix(gen): learningsMode is read from host config, not a hardcoded host name

resolvers/learnings.ts branched on ctx.host === 'codex' while every host
declared learningsMode — the field was decorative, and the 7 hosts configured
'basic' (cursor, slate, kiro, opencode, openclaw, hermes, gbrain) silently
received the 'full' cross-project flow their runtimes can't execute (it
depends on AskUserQuestion + gstack-config plumbing). Output now matches
declaration: basic hosts get the project-scoped search block.

Blast radius proof: all committed Claude SKILL.md files and the three golden
fixtures are byte-identical; the behavior diff lands only in the gitignored
external-host trees (hand-verified: .cursor review's learnings section swaps
the cross-project AskUserQuestion block for the project-scoped search).

* fix(gen): small config scrubs — openclaw blobs to real files, setup host drift, dead artifacts

- The three openclaw markdown blobs hardcoded inside gen-skill-docs.ts (which
  silently reverted any hand edit to their tracked outputs on regen) move to
  openclaw/templates/*.md source files; output shasums byte-identical.
- setup's --host allowlists gain cursor + slate — both fully registered hosts
  with generated output, but './setup --host cursor' exited 1 because two
  hand-rolled lists in setup had drifted from hosts/index.ts.
- scripts/proactive-suggestions.json deleted: 31KB regenerated on every run,
  read by nobody (the catalog-trim design's reader was never built); its
  emitter and three determinism tests (which guaranteed a file nothing reads
  didn't churn) retired with stays-retired pins.
- claude/SKILL.md.tmpl deleted: a complete 8.9KB skill that never generated
  output (directory name collides with the host id 'claude'), in no registry.
  Recoverable from git if ever wanted under a non-colliding name.
- openclaw's frozen extraFields.version '0.15.2.0' stamp dropped;
  includeSkills: [] no-ops omitted (the generator treats [] as absent);
  llms.txt 55 -> 54 skills.

* feat(gen): correct preamble tiers for the 8 silently-heaviest skills

With tiers now explicit, set them RIGHT by analogy to the tiered population:
scrape/diagram/open-gstack-browser (+ the connect-chrome symlink) -> tier 1
(launchers and artifact generators, like browse and make-pdf);
landing-report/pair-agent/skillify -> tier 2 (dashboards and session tools,
like health and canary); spec -> tier 3 (interactive planning, like the
plan-*-review family). Each tier-1 skill sheds 271 lines of onboarding
prose it never needed; tier-2 shed 20 each.

Verification per the review protocol: regen diff reviewed (pure
section-removal), skill-validation + size-budget + catalog-budget +
v0-dormancy suites green (822 tests), and live smoke of the tier-corrected
skills confirms the preamble renders the intended sections at each tier.
These skills have ~no eval coverage — stated honestly; the wave's gate-tier
eval run is the backstop.

* feat(test): e2e-gate — one tier-gate implementation, side-effect-free, with the trap pinned

The EVALS/EVALS_TIER gate was copy-pasted into ~40 test files and had drifted
into six different predicates — the drift that made 'eval:bg:all runs
everything' silently false. test/helpers/e2e-gate.ts owns the semantics now:
describeE2ETier(tier) + e2eTierEnabled(tier), env read at call time, zero
side effects (the existing e2e-helpers module runs a ~30s claude ping at
import under EVALS=1, so the gate lives in its own module; purity is pinned
by tests that scan imports and comment-stripped source).

The unit matrix pins all four env combos — including EVALS=1 with EVALS_TIER
unset -> SKIP, the exact trap that made eval:bg:all a non-run. The
tier-alignment tripwire gains a second regex for the helper shape (old shape
still detected — stragglers can't hide), and the sharded paid runner's
PRE-SPAWN tier classifier learns the helper shape too: without that, every
gate-sharded run would have spawned all 28 periodic shards just to skip them,
each paying the e2e-helpers import ping (~15 min of dead wall clock in the
CI-blocking lane). Verified: gate runs exclude the 29 periodic files,
periodic excludes the 8 gate files — identical to pre-migration.

* refactor(test): migrate the 36 tier-gated eval files to describeE2ETier

Mechanical two-liner swap in 34 files (each keeping its declared tier — all
36 predicates verified against E2E_TIERS before migrating); the two files
with compound gates (overlay-harness's EvalCollector feed, codex-e2e's
CODEX_AVAILABLE) keep their extra conditions via e2eTierEnabled. Tier
rationale comments preserved. codex-e2e/gemini-e2e/benchmark-providers keep
their distinct stderr-message gate shapes by design.

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

* refactor(test): skill-e2e + skill-llm-eval adopt the shared selection machinery

Both files re-implemented the diff-selection machinery e2e-helpers already
exported. The helper gained computeDiffSelection() (extracted, identical
behavior) and a trailing optional selection param on the *IfSelected helpers
(defaults preserve all 30+ existing importers). skill-e2e.test.ts drops ~120
duplicated lines; skill-llm-eval keeps its LLM_JUDGE_TOUCHFILES selection and
test.concurrent semantics via testConcurrentIfSelected.

Deliberate deltas, stated: skill-e2e.test.ts now honors the EVALS_TIER
intersection its local copy lacked (affects only direct bun test invocations
of that file — it matches no eval-script glob); its recordE2E gains the
helper's three diagnostic fields; skill-llm-eval sharded solo now runs
e2e-helpers' module-scope preflight it already ran in combined processes.

* fix(test): kill the silent-truncation race; exempt the tier-corrected shrinks

The full-suite shakeout (budgeted by the plan) surfaced both immediately:

1. server-embedder-terminal-port.test.ts stubbed process.exit and restored
   the REAL exit in its finally — but shutdown() schedules async work that
   can call process.exit AFTER restoration, killing the entire bun process
   mid-suite with exit 0 and NO summary. This is the silent-truncation class
   the new free-suite CI job guards against, reproduced locally on the first
   full run. Exit now stays a logging no-op between tests (late async exits
   become visible stderr lines, not process death); the true exit returns in
   afterAll.

2. The 80%-of-baseline shrink guard correctly flagged the six tier-corrected
   skills — their baseline was measured at the silent tier-4 default. Added
   to INTENTIONAL_SHRINKS with the reason, joining spec's double-preamble
   entry.

* fix(ci): free-tests step runs under bash (container sh rejects pipefail)

* fix(ci): free-tests curates 8 container-incompatible files with reasons

Second maiden-voyage shakeout round: 376 of 384 files ran green in the
container on the first completed pass. The 8 that can't run there yet are
excluded the same way the Windows shards curate POSIX-bound files — each
with its reason inline (headed-Chrome handoff, real-PTY round-trip, X server
management, extension-origin identity, the job's own TMPDIR override, and
three pre-existing env failures that fail on dev machines too). Anything
outside the list that fails still fails the job; trimming the list is
tracked follow-up.

* fix(test): gstack-config-key-locale — suppress the skill_prefix auto-relink side effect

The test invokes the repo's own bin/gstack-config, whose 'set skill_prefix'
auto-runs $(dirname $0)/gstack-relink — resolving the install dir to the
repo itself. In any environment where the loop shares a working tree (the
free-tests CI container, a fresh-HOME run), gstack-patch-names rewrote all
52 tracked SKILL.md names to gstack- prefixed, poisoning five unrelated
suites downstream (hermetic-skills-seeding, host-config golden, skill-census,
skill-validation, spec-template-sync). GSTACK_SETUP_RUNNING=1 is the
documented suppression; relink behavior stays covered by relink.test.ts's
mock install.

* fix(bin): gstack-codex-session-import — empty sessions dir exits 0 on Linux

GNU xargs runs 'ls -t' once even on empty input, listing the cwd and

run, which is why the NO_SESSIONS path only broke on Linux. xargs -r pins
the BSD behavior on both platforms.

* test(parity): rebaseline v1.57.7.0 → v1.64.1.0 + skeleton-cap headroom

The two parallel v1.64 waves (code-smell fix wave + main's #2571) each
added shared-preamble prose, pushing document-release / design-consultation
/ cso past their size ratios on the v1.57.7.0 anchor and four carved
skeletons (plan-ceo-review, plan-eng-review, office-hours,
design-consultation) 22-280 B over their absolute caps. New baseline is
union-normalized (skeleton + sections/*.md, matching what the harness
measures); caps get +~1 KB headroom each with per-cap rationale. The
v1.57.7.0 fixture stays in test/fixtures/ for the audit trail, and
capture-parity-baseline.ts now documents the union-normalization step so
the next rebaseline doesn't re-trip on it.

* fix(ci): free-tests container parity — tools, pinned bun, git identity, mutation tripwire

- Dockerfile.ci: add python3 (gstack-jsonl-merge/brain-sync/detach shell out
  to it), file (skill-validation's binary check), poppler-utils (make-pdf
  e2e gates hard-require pdftotext/pdffonts/pdfinfo), fonts-noto-color-emoji
  (emoji render gate, mirrors make-pdf-gate.yml). Fix the bun pin: the
  bun.sh installer ignores a BUN_VERSION env var, so the old form silently
  installed latest on every rebuild (observed 1.3.13/1.3.14 drift vs the
  1.3.10 devs run locally); pass the version as the positional arg.
- free-tests.yml: git identity + safe.directory for the git-exercising
  tests (container checkout is owned by a different uid than runner);
  post-loop tree-mutation tripwire that names a tracked-file-mutating test
  instead of letting downstream collateral confuse the report; skip the
  documented variants-retry-after timing flake.

* fix(bin): gstack-session-update — detached updater owns its stdio (SIGPIPE)

The backgrounded update subshell inherited the session hook's stdout/stderr
pipes. Once the hook exits and the caller closes them, any child that writes
— git pull's autostash notice, setup output — dies of SIGPIPE, logged as
PULL_FAILED exit=141 with an empty stderr capture (observed in the free-tests
container, and reachable by any production hook runner that closes stdio
promptly). Redirect the fork to /dev/null; all observability already flows
through the session-update log file.

* fix(test): gstack-decision-bins — explicit branch context for the scope filter

CI checks out a detached HEAD, where gitBranch() returns undefined on both

surface (filterByScope requires a matching non-empty ctx.branch). Pass the
branch explicitly on both sides — the filter logic is what's under test, not
git branch detection.

* fix(test): ring-buffer lease interplay — same TTL window, not same millisecond

Two back-to-back mintLease() calls each stamp Date.now() + TTL; when they
straddle a millisecond boundary the exact-equality assertion flakes
(observed in CI: expiries of ...525 vs ...526). Assert the expiries are
within a 50 ms window instead — the invariant under test is that leases
share a TTL policy, not that they mint in the same clock tick.

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

Fixes #1272

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

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

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

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

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

Tested on WSL2 + Windows 11 with Korean IME.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Under concurrent writers the shared filename races on the rename:

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

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

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

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

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

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

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

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

Asymmetric cleanup between two equivalent staleness conditions:

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

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

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

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

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

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

* fix(codex): resolve python for JSON parser

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

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

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

Closes #1244.

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

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

Behavior matrix:

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

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

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

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

Closes #1130.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* fix(ship): port #1302 SKILL.md edits to .tmpl + resolver source

PR #1302 added Verification Mode + UNVERIFIABLE classification + per-item
confirmation gate to ship/SKILL.md, but only the generated SKILL.md was
edited — not the .tmpl source or scripts/resolvers/review.ts. The next
`bun run gen:skill-docs` run would have wiped the changes.

Port the same content into the resolver and .tmpl so regeneration produces
the intended output.

* ci(windows): extend free-tests lane to cover icacls + Bun.which resolvers from fix-wave PRs

Closes #1306/#1307/#1308 validation gap. The four newly-added test files
already have process.platform guards so they run safely on both POSIX and
Windows lanes — only platform-relevant assertions execute on each.

Tests added to the windows-latest lane:
- browse/test/file-permissions.test.ts (#1308 icacls + writeSecureFile)
- browse/test/security.test.ts (#1306 bash.exe wrap pure-function path)
- make-pdf/test/browseClient.test.ts (#1307 Bun.which browse resolver)
- make-pdf/test/pdftotext.test.ts (#1307 Bun.which pdftotext resolver)

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

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

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

* chore: regen SKILL.md after fix wave

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

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

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

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

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

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

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

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

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

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

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

Garry TanandClaude Opus 4.7 d75402bbd2 v1.6.4.0: cut Haiku classifier FP from 44% to 23%, gate now enforced (#1135)
* feat(security): v2 ensemble tuning — label-first voting + SOLO_CONTENT_BLOCK

Cuts Haiku classifier false-positive rate from 44.1% → 22.9% on
BrowseSafe-Bench smoke. Detection trades from 67.3% → 56.2%; the
lost TPs are all cases Haiku correctly labeled verdict=warn
(phishing targeting users, not agent hijack) — they still surface
in the WARN banner meta but no longer kill the session.

Key changes:
- combineVerdict: label-first voting for transcript_classifier. Only
  meta.verdict==='block' block-votes; verdict==='warn' is a soft
  signal. Missing meta.verdict never block-votes (backward-compat).
- Hallucination guard: verdict='block' at confidence < LOG_ONLY (0.40)
  drops to warn-vote — prevents malformed low-conf blocks from going
  authoritative.
- New THRESHOLDS.SOLO_CONTENT_BLOCK = 0.92 decoupled from BLOCK (0.85).
  Label-less content classifiers (testsavant, deberta) need a higher
  solo-BLOCK bar because they can't distinguish injection from
  phishing-targeting-user. Transcript keeps label-gated solo path
  (verdict=block AND conf >= BLOCK).
- THRESHOLDS.WARN bumped 0.60 → 0.75 — borderline fires drop out of
  the 2-of-N ensemble pool.
- Haiku model pinned (claude-haiku-4-5-20251001). `claude -p` spawns
  from os.tmpdir() so project CLAUDE.md doesn't poison the classifier
  context (measured 44k cache_creation tokens per call before the fix,
  and Haiku refusing to classify because it read "security system"
  from CLAUDE.md and went meta).
- Haiku timeout 15s → 45s. Measured real latency is 17-33s end-to-end
  (Claude Code session startup + Haiku); v1's 15s caused 100% timeout
  when re-measured — v1's ensemble was effectively L4-only in prod.
- Haiku prompt rewritten: explicit block/warn/safe criteria, 8 few-shot
  exemplars (instruction-override → block; social engineering → warn;
  discussion-of-injection → safe).

Test updates:
- 5 existing combineVerdict tests adapted for label-first semantics
  (transcript signals now need meta.verdict to block-vote).
- 6 new tests: warn-soft-signal, three-way-block-with-warn-transcript,
  hallucination-guard-below-floor, above-floor-label-first,
  backward-compat-missing-meta.

* test(security): live + fixture-replay bench harness with 500-case capture

Adds two new benches that permanently guard the v2 tuning:

- security-bench-ensemble-live.test.ts (opt-in via GSTACK_BENCH_ENSEMBLE=1).
  Runs full ensemble on BrowseSafe-Bench smoke with real Haiku calls.
  Worker-pool concurrency (default 8, tunable via
  GSTACK_BENCH_ENSEMBLE_CONCURRENCY) cuts wall clock from ~2hr to
  ~25min on 500 cases. Captures Haiku responses to fixture for replay.
  Subsampling via GSTACK_BENCH_ENSEMBLE_CASES for faster iteration.
  Stop-loss iterations write to ~/.gstack-dev/evals/stop-loss-iter-N-*
  WITHOUT overwriting canonical fixture.

- security-bench-ensemble.test.ts (CI gate, deterministic replay).
  Replays captured fixture through combineVerdict, asserts
  detection >= 55% AND FP <= 25%. Fail-closed when fixture is missing
  AND security-layer files changed in branch diff. Uses
  `git diff --name-only base` (two-dot) to catch both committed
  and working-tree changes — `git diff base...HEAD` would silently
  skip in CI after fixture lands.

- browse/test/fixtures/security-bench-haiku-responses.json — 500 cases
  × 3 classifier signals each. Header includes schema_version, pinned
  model, component hashes (prompt, exemplars, thresholds, combiner,
  dataset version). Any change invalidates the fixture and forces
  fresh live capture.

- docs/evals/security-bench-ensemble-v2.json — durable PR artifact
  with measured TP/FN/FP/TN, 95% CIs, knob state, v1 baseline delta.
  Checked in so reviewers can see the numbers that justified the ship.

Measured baseline on the new harness:
  TP=146 FN=114 FP=55 TN=185 → 56.2% / 22.9% → GATE PASS

* chore(release): v1.5.1.0 — cut Haiku FP 44% → 23%

- VERSION: 1.5.0.0 → 1.5.1.0 (TUNING bump)
- CHANGELOG: [1.5.1.0] entry with measured numbers, knob list, and
  stop-loss rule spec
- TODOS: mark "Cut Haiku FP 44% → ~15%" P0 as SHIPPED with pointer

Measured: 56.2% detection (CI 50.1-62.1) / 22.9% FP (CI 18.1-28.6)
on 500-case BrowseSafe-Bench smoke. Gate passes (floor 55%, ceiling 25%).

* docs(changelog): add v1.6.4.0 placeholder entry at top

Per CLAUDE.md branch-scoped discipline, our VERSION 1.6.4.0 needs a CHANGELOG entry at the top so readers can tell what's on this branch vs main. Honest placeholder: no user-facing runtime changes yet, two merges bringing branch up to main's v1.6.3.0, and the approved injection-tuning plan is queued but unimplemented.

Gets replaced by the real release-summary at /ship time after Phases -1 through 10 land.

* docs(changelog): strip process minutiae from entries; rewrite v1.6.4.0

CLAUDE.md — new CHANGELOG rule: only document what shipped between main and this change. Keep out branch resyncs, merge commits, plan approvals, review outcomes, scope negotiations, "work queued" or "in-progress" framing. When no user-facing change actually landed, one sentence is the entry: "Version bump for branch-ahead discipline. No user-facing changes yet."

CHANGELOG.md — v1.6.4.0 entry rewritten to match. Previous version narrated the branch history, the approved injection-tuning plan, and what we expect to ship later — all of which are process minutiae readers do not care about.

* docs(changelog): rewrite v1.6.4.0; strip process minutiae

Rewrote v1.6.4.0 entry to follow the new CLAUDE.md rule: only document what shipped between main and this change. Previous entry narrated the branch history, the approved injection-tuning plan, and what we expect to ship later, all process minutiae readers do not care about.

v1.6.4.0 now reads: what the detection tuning did for users, the before/after numbers, the stop-loss rule, and the itemized changes for contributors.

CLAUDE.md — new rule: only document what shipped between main and this change. Keep out branch resyncs, merge commits, plan approvals, review outcomes, scope negotiations, "work queued" / "in-progress" framing. If nothing user-facing landed, one sentence: "Version bump for branch-ahead discipline. No user-facing changes yet."

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.

* 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.

* 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.

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

* 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.

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

* 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.

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

* 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.

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

* 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.

* 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

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

* 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.

* docs(security): document GSTACK_SECURITY_ENSEMBLE env var

  * What it does (L4c cross-model classifier, 2-of-3 agreement for BLOCK)
  * How to enable (GSTACK_SECURITY_ENSEMBLE=deberta)
  * The cost (721MB model download on first run)
  * Default behavior (disabled — 2-of-2 testsavant + transcript)

* 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.

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

* 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.

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

* 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).

  * Read/Glob/Grep tool-output ingress (P2) — SHIPPED earlier
  * DeBERTa-v3 opt-in ensemble (P2) — SHIPPED (b4e49d08 + 8e9ec52d

  * Cross-user aggregate attack dashboard (P2) — CLI SHIPPED
    (a5588ec0 + 2d107978 + 756875a7). Web UI at gstack.gg remains

* 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.

* 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.

TODOS: Read/Glob/Grep tool-output scan marked SHIPPED (was P2 open).
Cross-references the hardening commits so follow-up readers see the
full arc.

* 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.

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

* 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.

* 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.

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

* 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.

* 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.
