v1.78.0.0 fix: the two-red-lanes wave — AUQ collapse rooted, OSV green from 105, 18 community PRs absorbed, upgrade path can't eat installs (#2752)

* fix(auq): spawned trigger is objective — explicit declaration or STATUS echo, never inference (periodic-lane AUQ collapse)

The v1.76 spawned rule's parenthetical '(or your dispatch prompt marks this
session as spawned)' let the model INFER spawned status from a scripted-looking
prompt in a CI-looking session and silently auto-choose every review-phase
question: reviewCount=0 across the plan-review periodic E2Es (weekly run
33363624506, 9 of 14 failed shards; reproduced locally, zero AUQ fingerprints).
Env and hook paths were excluded by inspection: hermetic children echo
SESSION_KIND: interactive (CLAUDE_CODE_ENTRYPOINT=cli beats CI markers) and the
question-preference hook isn't installed there.

The trigger is now objective: the echoed SESSION_KIND: spawned STATUS line, or
an EXPLICIT dispatch-prompt declaration ("you are a SPAWNED subagent") —
declared, never inferred — with an absence-safe interactive fence: CI env vars,
scripted-looking or pasted prompts, and write-to-this-exact-file instructions
are NOT spawned markers. The prose channel stays because Task-tool subagents
inherit the parent env (no spawned prefix) — their dispatch prompt is the only
signal; #2733's env-prefix channel is untouched.

19 carve skeleton ceilings re-pinned with measured values (+~440 bytes/skill);
ship goldens refreshed for all three hosts; resolver pins extended with the
no-inference regression tests.

* fix: mktemp failure aborts loudly at all three skill-content sites; failed upgrade swap restores the backup (#2679)

An empty $(mktemp) result silently disabled the redaction pass (redact-doc
resolver, ship pr-body) and made /gstack-upgrade's vendored path destructive:
clone lands at "/gstack", the swap mv fails, and rm -rf then deletes BOTH the
live install's backup and "". All three sites now guard the assignment with a
loud exit; the vendored block additionally restores the backup when the swap
fails (same failure class — backup deletion after a failed mv) and the GitLab
MR path sends the SCANNED file's bytes instead of re-rendering an unscanned
heredoc. bin/gstack-redact rejects an explicit empty --from-file path instead
of silently falling through to stdin.

Receipts: 6 of 8 new regression checks fail on a v1.77.0.0 scratch worktree.

Fixes #2679

* fix(auq): the interactive fence classifies the session — it never nudges ask-count

Burn-in run 1 of the periodic repro overshot the review band (reviewCount=8 >
CEILING=7) with the fence's 'when unsure, ask' tail: that phrasing is a quota
nudge, not a classification default. The fence now states it only classifies
the session and never changes how many questions the skill asks. Pin added.

* fix(ci): OSV suppression config actually loads — explicit global --config + expiring, reasoned ignores

The ignore file was inert from v1.65.0.0: OSV-Scanner only auto-discovers
configs named osv-scanner.toml (no leading dot) and applies them
per-directory, so the root config never covered lib/diagram-render/bun.lock
either way. The workflow now passes --config=.osv-scanner.toml globally.
Every IgnoredVulns entry carries a reason with an upgrade trigger and an
ignoreUntil expiry (~90 days) so suppressions must be re-justified. A wiring
test pins flag ↔ filename ↔ entry hygiene so the file can never silently go
inert again.

* fix(deps): dependency wave — 105 OSV advisories → 3 reasoned suppressions, all lanes verified on the pinned scanner

Root: overrides pin ip-address 10.3.1 (defeats BOTH nested nodes — socks'
range pull and express-rate-limit's exact 10.1.0 pin, which a top-level bump
provably cannot reach) and sharp 0.35.0 (GHSA-f88m, HIGH; transformers still
pins ^0.34 upstream — smoke-tested round-trip); marked ^18.0.11; full in-range
lockfile refresh clears hono, fast-uri, protobufjs, qs, body-parser, nanoid,
uuid, immutable and friends.

lib/diagram-render (via its own build-script contract: exact pins edited,
fresh lock, dist rebuilt): mermaid 11.16.1, @excalidraw/excalidraw 0.18.1,
@excalidraw/mermaid-to-excalidraw 1.1.2 → 2.2.2 — the 1.x line exact-pinned
mermaid 10.9.x and dragged the entire duplicate mermaid-10 advisory chain
(dompurify 3.1.6, nanoid 3.3.3, lodash-es); the bundle shrinks 9.96 → 7.59 MB
with the duplicate mermaid gone. Nested exact pins that survived get scoped
overrides (nanoid 5.1.16, lodash-es 4.18.1).

Verification: clean-worktree frozen-lockfile installs (root + nested) + the
SAME osv-scanner release the action pins (v2.3.8) with the workflow's exact
scan-args → exit 0, 'No issues found'. Smoke tests cover the override
surfaces (sharp round-trip, ip-address lockfile assertion, marked parse);
socks + diagram-drift suites already pin the rest.

Supersedes #2695 (its own lockfile kept socks/ip-address@10.2.0; @anupamme's
report credited for the parallel diagnosis).

* fix(codex): a CLI that cannot execute no longer reports CODEX_MODE: ready

Follow-up to #2477. The model probe it added does a real round trip, but its
final branch is the `else` of a "model 400" grep, so it swallowed spawn ENOENT,
non-executable binaries and missing vendor payloads alongside genuine network
timeouts. All three are deterministic — retrying never helps — yet they landed
in the fail-open bucket and resolved to `ready`, so every Codex pass was
skipped in silence and the review reported itself complete.

Observed live: @openai/codex was on PATH with an empty
vendor/aarch64-apple-darwin/codex/ directory. gstack said `ready` for two
months while no Codex pass ran.

Three changes:

- `_gstack_codex_model_probe` classifies deterministic install failures (exit
  126/127, or stderr matching ENOENT/ENOEXEC/EACCES/"cannot execute binary
  file") as MODEL_UNUSABLE_INSTALL, exit 2, never cached — a reinstall is
  picked up on the next probe. Exit 124 and genuine transients still fail open,
  which is what #2477 intended.

- The preflight chain captures the probe's code instead of testing it for
  truthiness, so exit 2 routes to a new `broken_install` mode whose remedy is
  `npm install -g @openai/codex` rather than "check your model pin". A missing
  binary and an unusable model are different problems with different fixes.

- `_gstack_codex_version_check` no longer reads a broken CLI as healthy. It ran
  `codex --version 2>/dev/null | head -1`, which captures head's status, not
  codex's — and 2>/dev/null discarded the one diagnostic available. It now
  captures the real exit code and warns on non-zero. Empty-but-successful
  output stays silent, per the existing "empty output → OK" case.

Tests: 6 added to test/codex-hardening.test.ts covering both broken-install
shapes, the exit-2 contract, no caching, the transient still failing open, the
model 400 still classifying as MODEL_UNUSABLE, and the version-check warning.
845 pass / 0 fail across all 8 suites touching the changed files.

Closes #2742

Wave-amended: autoplan hand-maintained preflight chain completed (tmpl+render); install-signature grep gated on failed spawn only; goldens regenerated against the wave tree (author's golden commit 5797d326 superseded); +2 tests

* feat(redact): add Groq, Tavily and Notion API key patterns

* fix(redact): stop reporting .env.local as an internal hostname

`internal.hostname` ends in `.local|.prod|.staging|…`, so `.env.local`
matches on `env.local` and a dotenv FILENAME is reported as a leaked
internal host.

The collision is not exotic. It fires on `--env-file=.env.local` in an npm
script, `.env.staging` in a README, `.env.prod` in a .gitignore — ordinary
lines on branches that leak nothing. Measured on one private repo, three of
four MEDIUM findings in a routine push were this, and the fourth was a
deleted localhost URL. That ratio is the real cost: a scanner that reports
package.json is one people learn to skim, and skimming is how the HIGH
finding it exists for gets missed.

The guard follows the `insideUuid` precedent and stays deliberately narrow —
it exempts only a span beginning `env.` immediately preceded by a dot, i.e.
the literal `.env.<suffix>` form. `api.corp.local`, `build-7.internal` and
`myenv.local` all still report.

The test pins both directions, and the negative controls are the point: an
exemption written as "any span ending .local" would pass the dotenv half
while quietly gutting the pattern for every real host. Verified red/green —
with the validate hook removed, exactly the 6 dotenv cases fail and all 9
real-host controls still pass.

* fix: don't flag git SSH remotes as pii.email

`pii.email` matches the `git@github.com` inside
`git@github.com:acme/widgets.git`. That is a transport user@host, not a
person's address, so any diff touching a clone URL -- a deploy config's
repo URL, a submodule entry, a README clone line -- draws a spurious
MEDIUM from the pre-push hook.

Suppressed by URL shape rather than by adding `git` to
EMAIL_ALLOW_LOCALPARTS. A bare `git@` allowlist entry would also
suppress a genuine address at a domain that merely begins with "git"
(git@gitmail.com), converting a false positive into a false negative --
the worse failure for a guardrail. Two shapes are accepted:

  - `<user>@<host>:<path>.git` for ANY host, covering self-hosted
    remotes, plus the equivalent ssh:// URL form.
  - `git@<known-host>` for github.com, gitlab.com, bitbucket.org and
    ssh.dev.azure.com, whose bare form appears in docs and in
    `ssh -T git@github.com` connectivity checks with no path at all.
    Matched exactly, so gitmail.com is unaffected.

emailAllowed now receives the normalized text and the span offset so it
can see that surrounding shape; it had only ever been passed the matched
span.

Tests pin both directions: the SSH remotes go quiet, and a real address
still fires -- including at a git host (alex@github.com) and at a
git-prefixed domain (git@gitmail.com).

* fix(redact): install-prepush-hook refreshes a stale managed hook

The marker check returned before the only writer, so once a repo had the
hook, no later change to the wrapper could ever reach it. The `printf x`
fail-open fix (v1.64.0.0) has still not landed in any repo that received
the hook before it, and a wrapper naming a gstack that has since moved
stays pointed at a dead path for the same reason.

Compare the body against what this version generates: rewrite on drift,
stay a no-op when identical. The chained pre-push.local is untouched on
both paths.

The existing trailing-newline regression test cannot catch this — it
installs into a repo with no prior managed hook, the one case that was
never broken.

* fix(gbrain-detect): classify gbrain >= 0.43 held-lock refusal as engine-locked

gbrain 0.43+ refuses a held PGLite lock with exit 1 and the message
"GBrain's local database is already open through `gbrain serve` (MCP,
PID N)" instead of the pre-0.43 exit 124 + "connect timed out" that
the #2194 branch matches. The message matches no known pattern, so the
classifier falls through to the defensive broken-config default — and
Step 1.5 of /setup-gbrain and /sync-gbrain then tell the user to move a
perfectly healthy config.json aside and re-init the engine.

Reproduced live on gbrain 0.43.0.0, 0.44.0.0 and 0.46.30.0: with a
serve holding the lock, gstack-gbrain-detect reports
gbrain_local_status=broken-config; after stopping the serve it reports
ok with the same untouched config.

Match on the stable substring "already open through", mirroring the
existing #2194 branch semantics: engine-locked for pglite, broken-db
otherwise. Adds a fake-gbrain behavior for the 0.43+ refusal plus two
cases (pglite -> engine-locked, postgres -> broken-db).

* fix(memory-helpers): a slow gitleaks probe no longer disables secret scanning

`gitleaksAvailable()` cached every failure the same way, so a 2s timeout on
`gitleaks version` was recorded as "the binary is absent" for the rest of the
process. One busy moment and the whole ingest ran unscanned behind a single
stderr line — a fail-open outcome decided by machine load rather than by
anything about the machine's setup. The caller only acts on
`scanner === "gitleaks"`, so every later file was written with no scan and no
second warning.

The probe now classifies three outcomes. ENOENT (and a present-but-unusable
binary: bad exit, EACCES) stays cached — that is a fact about the box, and
re-probing it per file would be waste. A timeout gets one retry on a 10s
budget, and if that also expires nothing is cached: the file is reported
unscanned, the warning says so in those words, and the next file probes again.

Observed under the 7-way sharded free-test runner, where spawning a shell
script inside a temp bin dir took longer than the 2s budget.

Tests: the retry path, the no-cache-on-timeout path (the second call must
re-probe), and the cached-absent path. The fake gitleaks hangs for 30s rather
than racing a short sleep against a short budget, and the budgets are chosen so
load cannot flip an outcome: 30s where the retry MUST answer, 800ms where the
probe MUST expire. An earlier draft used 1s/5s and flaked under the same shard
runner this commit is about. The existing probe test pinned `detect` to
calls[1], which a retry breaks; it now asserts the order instead of the index.

* fix(make-pdf): pdftotext version and flavor probe returns unknown on poppler

describeBinary reports version="unknown" flavor="unknown" for every poppler
install, so logDiagnostics prints nothing useful on the most common
implementation. Two independent causes:

1. poppler writes the -v banner to stderr and exits 0. execFileSync returns
   stdout (empty) and does not throw on a zero exit, so the stderr fallback in
   the catch block is unreachable. The in-code comment already notes poppler
   exits 0, but only the throwing path reads stderr.

2. flavor is matched against the version line alone. poppler prints
   "pdftotext version 26.06.0" on line 1 and names itself on line 2,
   "Copyright ... The Poppler Developers", so even a working stderr read
   yields "unknown".

Switch the probe to spawnSync, which returns both streams regardless of exit
status, match the version banner rather than assuming line 0, and derive the
flavor from the full output.

Measured on poppler 26.06.0 (Homebrew, macOS), same machine and binary:

  before: { version: "unknown",                  flavor: "unknown" }
  after:  { version: "pdftotext version 26.06.0", flavor: "poppler" }

xpdf is unaffected: it exits non-zero and names itself on line 1, so it
resolved correctly before and still does.

Tests use shell shims reproducing each vendor's banner, stream and exit status,
since a real pdftotext cannot be assumed present in CI. Two of the four fail on
this commit's parent; the xpdf and no-banner cases pass there and are included
as regression guards rather than red-proofs.

* fix(open-gstack-browser): pre-flight cleanup never killed the stale daemon

Step 0 read the old pid with `grep -o '"pid":[0-9]*'` and Step 2 read the port
the same way. Neither can match. Every writer of that file in
browse/src/server.ts serializes with `JSON.stringify(state, null, 2)`, so the
bytes on disk are `"pid": 12060` — colon, space, digits.

The failure was silent in the worst way. `_OLD_PID` came back empty, the kill
never ran, browse.json was deleted anyway, and the next `connect` died with
"existing daemon has different config (proxy/headed mismatch)" — an error
pointing at proxy/headed flags rather than at the cleanup that no-opped. Caught
against a daemon left over from a reboot: the operator was told to check flags
they had never passed.

Both patterns now accept optional whitespace. The new tripwire does not match
strings — it RUNS the snippets the skill hands the agent, against a state file
written exactly the way the server writes one, and asserts pid and port come
back out. A third case pins the coupling to `JSON.stringify(state, null, 2)`,
so a switch to compact JSON surfaces as a failing expectation rather than as
silence.

* fix(browse): honour CHROMIUM_PROFILE in cli profile-lock cleanup

cli.ts resolved the Chromium profile dir with a hardcoded
$HOME/.gstack/chromium-profile, while browser-manager launches the profile
returned by config.resolveChromiumProfile(), which honours CHROMIUM_PROFILE
and GSTACK_HOME.

killOrphanChromium() and cleanChromiumProfileLocks() are called with no
argument, so whenever CHROMIUM_PROFILE was set they cleaned locks for, and
killed Chromium on, the DEFAULT profile rather than the one being launched.
Starting a browser with a custom profile therefore evicted an unrelated
browser running on the default profile.

Delegating to resolveChromiumProfile() also picks up GSTACK_HOME and
os.homedir(), so the cleanup path now matches the launch path on Windows
where HOME is frequently unset.

* fix(auq): the interactive fence is quota-silent — it defers to the skill's own decision points

Burn-in calibration: run 1 (fence tail 'when unsure, ask') overshot the
plan-ceo review band at reviewCount=8; run 2 (tail mentioning 'HOW MANY
questions') undershot at 1. Any ask-count language in the fence anchors the
model in one direction or the other. The tail now says only: classify as
interactive, then follow the skill's own decision-point instructions exactly
as written. Pins updated to forbid count language in either direction.

delegation and forbids the hardcoded path from returning.

* fix(browse): preserve return value for async IIFE expressions in js/eval (#2727)

Wave-amended: test moved to browse/test/ (browse unit-test convention); trailing-semicolon normalization kept — it is load-bearing for the expression wrapper

* fix: bin writers drop data on Windows paths with an apostrophe

Two independent Windows git-bash bugs in the bin writers, both silent
because callers invoke these scripts with 2>/dev/null and do not check
the exit status — a hard failure was indistinguishable from success.

Bug 1 — apostrophe in the checkout path breaks the bun -e program.
gstack-learnings-log, gstack-question-log and gstack-telemetry-log build
a bun -e program as a double-quoted shell string and interpolate
SCRIPT_DIR into a single-quoted JS import specifier. A path such as
C:/Users/Someone's PC/... closes the JS string literal early and Bun
fails to parse ("Expected ; but found s"). Every learning write and every
plan-tune question event no-oped; telemetry error redaction fell to its
fail-closed null path. The #1950 cygpath -m guard did not cover this —
cygpath normalises the drive form but does not remove the apostrophe.

Fixed by not interpolating the path at all: cd into the module root and
use a relative import specifier, which is immune to apostrophes, spaces,
backslashes and MSYS paths alike. The one remaining interpolated data
path in gstack-developer-profile (readFileSync of PROFILE_FILE) is passed
via the environment instead, matching do_log_session in the same file.

Bug 2 — gstack-developer-profile --derive fails on an MSYS-form
GSTACK_HOME. GSTACK_HOME defaults to $HOME/.gstack, which under git-bash
is /c/Users/..., and Bun on Windows cannot open that form (ENOENT). This
script carried no cygpath guard at all. Fixed by normalising GSTACK_HOME
once, before PROFILE_FILE / LEGACY_FILE / the events path are derived
from it, so all three pick up the normalised value.

Adds test/hostile-path-writers.test.ts, which runs the bins from a
directory whose name contains an apostrophe and asserts that rows are
ACTUALLY WRITTEN (not merely that the exit code is 0 — exit-code-only
checks are what masked bug 1). The apostrophe repro is OS-independent:
SCRIPT_DIR derives from the script's own location, so a copied checkout
under a hostile directory name reproduces bug 1 on Linux/macOS CI too.

Wave-amended: all four writers unified on the env-var import pattern the PR already used in gstack-developer-profile (no CWD-dependent module resolution)

* fix(memory-ingest): stop two silent transcript-ingest failures

Two independent bugs made transcript pages silently fail to reach the brain.

1. Frontmatter fence gluing. buildTranscriptPage() built the closing "---"
   with no trailing newline, and session bodies always start with "## ", so
   the rendered page ended "...---## User". gbrain's frontmatter matcher
   (/^---\r?\n([\s\S]*?)\r?\n---(\r?\n|$)/ in src/core/markdown.ts) requires
   the closing "---" to end its own line, so it skipped the glued fence,
   latched onto the next standalone "---" in the transcript body, parsed the
   prose between as YAML, and dropped the page with "Invalid YAML frontmatter".
   Transcripts with no later "---" fell back to body-only, silently losing
   their frontmatter. Fix: emit the fence on its own line with a blank
   separator, matching renderPageBody()'s artifact branch.

2. Slug collisions. Two source files can map to one path-derived slug (a
   session resumed under the same id on one day, or two ids sharing a 12-char
   prefix). writeStaged() names each file "${slug}.md", so the second
   overwrote the first; gbrain collected N-1 of N staged files and the
   reconciliation guard failed the whole batch every run. Fix:
   disambiguateSlugs() keeps the first occurrence and gives each later collider
   a stable "-<sha8(source_path)>" suffix (deterministic, and slug + page_slug
   move together so writeStaged, the failure mapping, and state recording agree).

Exports buildTranscriptPage, renderPageBody, and disambiguateSlugs for tests.
Adds regression tests for both failures.

* fix(gbrain): a slow --version probe classifies as timeout, never no-cli (#2716)

resolveGbrainBin's bare catch collapsed 'gbrain missing' and 'gbrain present
but the 2s --version budget expired' into the same null — freshClassify then
said no-cli, which the --is-ok whitelist from #1964 does NOT forgive, so a
bun-shim install on a loaded POSIX box silently lost every brain-aware block.
The probe now returns a discriminated result (cached per-process, same
lifetime the old null had) using the same killed/SIGTERM/ETIMEDOUT
discrimination the sources-list probe below already uses; timeout routes to
the forgiven 'timeout' status. GSTACK_GBRAIN_VERSION_PROBE_TIMEOUT_MS test
override added (same precedent as the sources-probe override).

* fix(codex): close the consult-mode fence, report turn.failed as a failure, capture exit codes portably (#2671, #2669)

Three defects in the codex skill sections:

- The resumed-session bash block never closed its fence; every fenced region
  after it inverted (prose rendered as code, the synthesis-recommendation tail
  rendered inert). A repo-wide fence-pairing test now scans every generated
  SKILL.md and sections/*.md with a CommonMark-faithful state machine (an
  info-string opener inside a fence is literal content — nested template
  examples in document-generate/make-pdf stay legal; a file ending inside a
  fence fails).

- The JSONL parsers had no turn.failed branch: a turn that STATED its failure
  was reported as 'possible mid-stream disconnect'. Challenge and consult now
  print the event's error and run a three-way completeness check (failed-with-
  reason / silent-disconnect / ok); consult previously had no completeness
  check at all.

- ${PIPESTATUS[0]} is empty under zsh, so hang detection never fired and
  every clean run printed a spurious '[codex exit ]'. All three capture sites
  use ${PIPESTATUS[0]:-${pipestatus[1]}}, pinned statically and EXECUTED
  under real bash and zsh in the new test. Expect a step-change in
  codex_timeout telemetry — the counter starts firing for zsh users.

Receipt: the portability pin fails on a v1.77.0.0 scratch worktree; the fence
fix is structural (17 → 18 fence lines, tail no longer inside a block).

* fix: outside-voice fallback is labeled honestly — same model family, not cross-model (#2735)

When Codex is unavailable, the plan-review outside voice falls back to a
Claude subagent and the copy sold it as 'cross-model coverage' with 'genuine
independence'. Fresh context is real; cross-model validation is not — a user
weighing 'both reviewers agree' deserves to know both reviewers share a model
family. Six canonical strings fixed at the resolver source (constants.ts
not_installed/not_authed, review.ts outside-voice bullet + three dispatch
paragraphs); ~10 generated docs and the ship goldens regenerated. Printing
the resolved fallback model at dispatch time is descoped as a functional
change (follow-up in the wave dispositions).

* fix(relink): skill_prefix patches the gbrain render too — the file the host actually serves (#2738)

gstack-relink linked SKILL.md from RENDER_DIR when a gbrain render was active
but ran gstack-patch-names only on INSTALL_DIR, so the served frontmatter kept
the unprefixed name and skill_prefix=true silently no-oped for every
brain-aware skill. The render tree (user-owned, untracked) is now patched too;
gstack-patch-names is idempotent so repeat relinks never double-prefix. The
gen-skill-docs note that pointed users at relink now describes what relink
actually covers.

Receipt: the new test fails on a v1.77.0.0 scratch worktree (served render
keeps 'name: qa').

* fix(render): section refs point at the FINAL render dir, never the tmp swap dir (#2692)

gen-skill-docs bakes its --out-dir into rendered CONTENT (rewriteSectionBase),
and both swap-in callers (setup, gstack-config gbrain-refresh) render into
claude.tmp.<pid> before the #2569 atomic rename — so every rendered skill
carried ~9 dead section Read paths that pointed at a directory the swap had
just deleted. New --link-root flag names the final serving dir (defaults to
--out-dir for direct-render callers: bin/dev-setup, dev-skill.ts, mkdtemp
tests — full caller audit in the wave notes); the rewrite now uses a
replacement callback so a $-bearing configured path can't expand as $& in a
replacement string. The swap logic itself stays byte-identical. Tests pin the
generator contract (tmp out-dir files reference the final dir, $-bearing
path included) and both callers' wiring.

* feat(setup): persistent timeline Stop hook opt-out — timeline_stop_hook config gate (#2677)

--no-team is a one-shot teardown, so every later bare ./setup (including the
ones /gstack-upgrade runs) re-registered the timeline Stop hook with no way
to say 'never'. New gate mirrors the plan_tune_hooks pattern: flag
(--timeline-stop-hook/--no-timeline-stop-hook) > env
(GSTACK_TIMELINE_STOP_HOOK) > saved config (timeline_stop_hook) > default
yes. An explicit flag persists to config so the decision survives upgrades;
an explicit 'no' also removes a live registration (reconciliation), so the
opt-out works against installs registered by an older setup. --no-team
semantics unchanged (NO_TEAM_MODE is never initialized from config). Full
gstack-config surface: DEFAULTS entry, header docs, list/defaults
enumeration, warn-and-default validation.

* fix(browse): tame the macOS headless GPU spin + reap the lock-less headless Chromium on stop (#2709)

Two defects in one report. On macOS 26 / Apple Silicon the headless-shell GPU
process pegs ~800% CPU indefinitely after real page work and --disable-gpu
alone is not enough; the reporter validated that adding
--disable-software-rasterizer/--disable-gpu-compositing/--disable-gpu-watchdog
drops it to 0.0% with screenshots still working. The flag block is a pure
platform-parameterized function (unit-tested on any host), darwin-gated,
headless-only (buildGStackLaunchArgs feeds the headed/GBrowser paths where
GPU-off is wrong), with a GSTACK_DISABLE_GPU=off escape.

Separately: the headless launch has no userDataDir, so it never writes the
SingletonLock that killOrphanChromium walks — 'browse stop' reported success
while the orphan kept spinning. The daemon now records the launched child's
pid + wall-clock start time in the state file (the xvfbPid/xvfbStartTime
contract), and stop paths reap a survivor only after verifying BOTH the
recorded start time and a Chromium-looking cmdline — a recycled PID, even one
running a different legitimate Chromium, is never killed (identity tests
include the coreutils-shebang trap that defeats argv0 renames).

macOS efficacy is per the reporter's validation; live re-verification on
Apple silicon is tracked in TODOS.md.

* fix(wtree): a failed touch falls through to the HEAD seed instead of reopening the racy window (#2687)

The v1.74 racy-git fix carries the real index's mtime onto the temp copy —
but its 'touch -r … || true' meant a FAILED touch silently kept the copy's
fresh stamp, marking every entry non-racy and reopening the exact same-size-
rewrite hole. A failed touch now discards the copy and seeds from read-tree
HEAD (slower; every entry re-hashed; fingerprint stays honest).

Verification for #2687 itself: the reporter's same-size-rewrite repro run 20
iterations against this tree — 0 misses (the underlying race was fixed by
v1.74's b1485d88 with its own regression test; this wave verifies and closes,
it does not claim that fix). Receipt: the stubbed-touch test fails on a
v1.77.0.0 scratch worktree.

* fix(redact): large reports survive the pipe — exitCode instead of process.exit; inert test payload

The wave's PR quality gate failed closed: gate-secret-scan.mjs pipes the
diff's added lines into gstack-redact and parses the JSON report, but
process.exit() discards stdout still buffered in the pipe — this wave's
646-finding report (202 KB) is the first big enough to arrive truncated
(~145 KB) at node's collector, so JSON.parse failed and the gate read
'no report' as HIGH. The report and auto-redact body paths now set
process.exitCode and let the runtime drain stdout; exit-code contract
unchanged (verified 0/2/3 end-to-end). Also: the C1 test's stdin payload no
longer uses a provider-prefix credential shape (the gate correctly flagged
it; the content was never read on the error path under test).

* test(memory-ingest): fence regression test survives Windows tmpdirs

Wave polish on the #2699 absorption: the hand-built JSONL interpolated the

escape, the user line was silently dropped, and the body started at
'## Assistant' (Windows Free Tests red). JSON.stringify the path.

* fix(auq): the interactive fence ends at classification — all behavioral tails removed

The pinned-container periodic lane proved the collapse dead (reviewCount 0 →
7/8/5 across the AUQ suite) but flagged the fence's remaining behavioral
clause: 'never adds, removes, or batches the skill's decision points' broke
the paired-finding control (5 > 4 — it suppressed the batching that fixture
expects), and the band overshot its ceiling (8 > 7). Every behavioral tail
tried so far skewed counts somewhere ('when unsure, ask' → 8; 'HOW MANY
questions' → 1; 'never batches' → paired control red). The fence now ends at
'When unsure, default to interactive.' — classification only, zero behavior
words. Pins forbid every tried-and-failed phrasing.

* fix(auq): the spawned trigger is the STATUS echo, nothing else — prose channel removed from the eager path

Two pinned-container periodic rounds showed that ANY dispatch-prompt
declaration channel in rule 1 keeps question counts unstable (round 1, fence
with behavioral clause: paired control 5>4, band 8>7; round 2, bare fence:
intermittent 0s return, paired control breaks both directions). The stable
regime CI was calibrated against had no spawned prose in the eager path at
all. Rule 1 now keys on exactly one machine-verifiable thing: the preamble's
own SESSION_KIND: spawned STATUS echo. No text from a dispatch prompt, file,
or page can flip a session to auto-choose (the strongest anti-injection
form). Subagents that missed the env marker are caught at FAILURE time by
the AUQ hooks' spawned escape (explicit declaration, never inference) — a
channel that never enters an interactive session's eager reasoning.

This reverses the wave's earlier explicit-declaration middle ground (and
adopts the outside voice's twice-made echo-only argument) on the new
evidence. #2733 protected: skill-e2e-docsync-spawned (gate) passes 1/1 on
this prose — the ship Step-18 dispatch forces the env prefix, so the echo
fires there.

* fix(browse): chromium reap works off-Linux and on every stale-state path

readPidCmdline fell back to '' on darwin (no /proc), so the identity gate
never matched and reapRecordedChromium was inert on the platform #2709's
GPU-spin reap actually targets — it now falls back to ps -o command=.
readPidStartTime no longer throws when ps is missing (Windows): a launch
must never die to a reap-bookkeeping probe. Three stale-state cleanup
paths (dead-daemon stop, startServer stale cleanup, headed-connect) now
reap the recorded chromium BEFORE unlinking the state file instead of
orphaning it, and the stop-path wait polls (100ms steps, 1s cap) instead
of sleeping a fixed 500ms. Wiring pinned: server-state pid/start-time
write, all five cli.ts reap call sites, headless-only GPU-flag push.

* fix(browse): chained IIFE + second statement no longer misclassified as one expression

isSingleParenOrIifeExpression accepted any tail after the initial group's
close as long as trailing chars looked chain-ish, so
`(async()=>{await 1})().then(x=>x); console.log('done')` classified as a
single expression and the expression wrapper emitted a SyntaxError. The
tail is now consumed as a strict member/call/index/optional-chain walk to
END of input via a shared string/escape-aware findBalancedClose scanner;
anything else (';', operators) demotes to the block wrapper. Negative +
positive tests added.

* fix(codex-probe): timed-out probe (124) keeps its fail-open contract

Exit 124 reached the string-signature branch before the timeout fail-open,
so a slow probe whose partial output happened to quote 'permission denied'
classified as MODEL_UNUSABLE_INSTALL — a deterministic-broken verdict from
a transient condition. 124 is now excluded from the signature branch, and
the detect/display greps share one hoisted _BROKEN_SIG regex (they had
already drifted: display dropped 'not executable').

* fix(codex): JSONL parser initializes its state vars in both modes

challenge-mode initialized turn_completed_count but tested turn_failed via

and turn_failed up front and use plain checks — same semantics, no
module-globals introspection.

* fix(ship): PR/MR create aborts on a missing or empty scanned body file

Both the gh and glab send blocks now guard [ -s "$PR_BODY_FILE" ] and the
prose restates that the variable comes from the scan block — bash blocks
run in separate shells, and an unset/empty path would previously send an
empty body (gh) or cat's error output (glab) instead of the scanned bytes.
Codex/factory ship goldens regenerated.

* fix(upgrade): abort when a stale .bak already exists at the install path

A leftover $INSTALL_DIR.bak from a crashed upgrade would make the mv nest

refuses to start and tells the user to inspect/salvage the backup.

* fix(setup): typo'd timeline-stop-hook value warns instead of persisting

--timeline-stop-hook=noo silently normalized to yes AND wrote yes to
config — a persisted decision the user never made. Unrecognized values now
warn (naming the source), apply the default for this run only, and skip
the config write. The opt-out log line names the actual decision source
(flag/env/config) and no longer claims a removal that may not have

One shared _gitleaksWarned flag served two different messages: a 'machine

warning — the user never learned scanning was off for good. Split into

* refactor(lib): shared isExecTimeout helper; export GbrainBinProbe

The killed/SIGTERM/ETIMEDOUT discrimination was hand-rolled at three sites
(gbrain version probe, engine classifier, gitleaks probe) and free to
drift; it now lives once in lib/gbrain-exec.ts. GbrainBinProbe is exported
(it's the return type of exported probeGbrainBin) and the cache carries a
rationale comment: caching a timeout for process lifetime is deliberate —
the memo dedupes the ~3 probes of one short-lived preamble process.

--out-dir and --link-root shared near-identical inline parsing; one helper

independently) — it now describes the real behavior.

The parser's turn.completed/turn.failed/disconnect semantics were pinned

not-a-disconnect, silence -> disconnect warning, SESSION_ID echo), with
byte-equivalence safety pins on the bash double-quote extraction. The
fence scanner also gains CommonMark opener-length tracking: a 4-backtick
fence wrapping a 3-backtick example no longer false-positives, with a
self-test.

* fix(memory-helpers): per-run cooldown bounds the slow-gitleaks probe cost

Retrying a slow probe per FILE (#2715's slow!=absent split) re-paid up to
probe+retry (12s default) per file — an 887-file ingest on a loaded box
spent hours re-asking the same slow question. After 3 consecutive slow
answers the run stops probing and warns once that remaining files go
unscanned; the availability cache is still never written, so the next
process probes fresh. Slow/absent discrimination is unchanged.

* fix(memory-ingest): slug assignments persist across runs via the state consult

First-occurrence-keeps-bare was walk-order-dependent ACROSS runs: a source
that got the suffixed slug once could take the bare slug the next run (its
collider aged out or was skipped as unchanged), leaving gbrain holding the
same transcript under two slugs — and a NEW collider could claim a bare
slug that state shows belongs to an unchanged source, silently overwriting
that page. disambiguateSlugs now consults state.sessions: a recorded slug
stays owned by its source_path, re-ingested sources keep their slug
verbatim, fresh assignments never take another source's slug, and legacy
duplicate records (pre-#2724 overwrites) resolve first-owner-wins and
self-heal on the next state write. Stateless behavior is unchanged.

With no spawned echo, the session is interactive no matter how automated it looks.
 2. **`CONDUCTOR_SESSION: true` echoed** → do NOT call AskUserQuestion at all (neither native nor any `mcp__*__AskUserQuestion` variant): render EVERY decision brief as the **prose form** below and STOP. Proactive, not a failure reaction — Conductor disables native AUQ and its MCP variant is flaky (`[Tool result missing due to internal error]`). **Auto-decide preferences still apply first** (failure-fallback item 1 below): proceed with a surfaced auto-decide option, no prose — enforced HERE since no tool call ever happens. Capture each Conductor prose brief with `bin/gstack-question-log` (the PostToolUse hook never fires on a prose path; `/plan-tune` learning depends on it).
