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.

The parser's turn.completed/turn.failed/disconnect semantics were pinned
by shape only — now the python block is extracted from both RENDERED
sections and run against synthetic event streams (tokens line, FAILED +
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.

SPAWNED_ESCAPE_SENTENCE's tightened wording had no pin: positive pins on

Both the gh and glab send blocks now guard [ -s "$PR_BODY_FILE" ] and the

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.

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.

Wave polish on the #2699 absorption: the hand-built JSONL interpolated the
raw tmpdir into a JSON string — on Windows (D:\a\...) that's an invalid

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).

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

--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

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.

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

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

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).

resolveGbrainBin's bare catch collapsed 'gbrain missing' and 'gbrain present

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

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.

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)

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.

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.

`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.

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).

`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).

`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.
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.

The /ship Design Review step skipped the checklist because the generated path omitted the gstack/ install segment. Sync the generated skill doc and pin a regression assertion.

Lock paths are checked before pgrep. Spreading process.env let a runner
GBRAIN_HOME with a live lock refuse the case before the stub ran.

The only non-dry-run --code-only child hits #1734's PATH-resolved
autopilot probe. A live host daemon is a correct refuse; the test
cannot inject processRunning. Neutralize pgrep in the fixture bindir
instead of adding a production env hatch.

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.

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.

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

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.
