Summary

The v1.78.0.0 fix wave — both red weekly CI lanes restored (periodic AUQ-collapse regression rooted in v1.76's inferable spawned trigger; OSV lane green from 105 advisories via a real dependency pass and a suppression file that actually loads), 18 community PRs absorbed with authorship preserved, 9 confirmed no-PR bugs fixed directly, led by the destructive #2679 upgrade-path guard.

Community PRs absorbed (18, authorship preserved on the branch commits; please keep the Co-authored-by trailers below in the squash message):

New fixes (11):

Test Coverage

Tests: 8,519 → 8,660 (+141). Every behavior fix carries a regression test verified red on a scratch worktree of v1.77.0.0 via base-compatible reproducers (compile-failure receipts don't count). New structural guards: generated-doc fence pairing (with CommonMark opener-length tracking), PIPESTATUS portability (executed under real bash+zsh), the codex JSONL parser executed under real python3, OSV config wiring with mandatory ignoreUntil, redact CLI empty-path, cli.ts profile-dir delegation, browse stop-reap wiring pins, and the v1.78.0.0 migration's first dedicated suite. The redact pipe-drain test was proven red against a copy of the bin with the old exit pattern restored (65,536-byte truncation reproduced).

Pre-Landing Review

/plan-ceo-review (HOLD SCOPE, CLEAR, 8 findings absorbed) + /plan-eng-review (CLEAR, 3 findings absorbed) + two Codex outside-voice passes (31 points total; 22 absorbed — peelable-first commit order, ordered-SHA picks, base-compatible receipts, start-time PID identity, explicit OSV --config, ignoreUntil expiry, bash+zsh execution tests; rejections recorded with rationale in the plan).

Ship-time review army (7 specialists + red team, 92% coverage audit, 2 cycles): three CRITICALs found and fixed (the darwin reap identity probe was inert — /proc read on a platform without /proc; a chained-IIFE-plus-statement eval misclassification; a launch-path crash where ps is missing), all 8 coverage-audit gaps closed as tests, and cycle 2's single finding (a Windows-lane PATH hazard in a new test) fixed. Three judgment calls went to the maintainer: gitleaks probe cooldown (implemented), cross-run slug persistence (implemented), land-and-deploy anonymous-HTTPS ownership edge (deferred to #2765).

Eval Results

FINAL: all 20 PR checks green including all six paid gate slices and the fail-closed slices-report (three consecutive rounds). OSV verified green both locally (pinned v2.3.8, frozen clean installs, exit 0) and via workflow_dispatch on the branch. The v1.76 periodic AUQ collapse is dead across three pinned-container periodic dispatches on this branch (deterministic reviewCount=0 never recurred; round-3 passes every test that drove rounds 1-2). The periodic lane itself remains churn-red as it was BEFORE the wave — it has never been green in its v1.77 shape; residual classification with receipts (pre-existing exited/hits=[] class reproduced on clean v1.77, band-edge variance, known flakes) is in #2756. Free suite green (8,660 tests under xvfb; the earlier sandbox handoff failures were rooted to a missing Xvfb package plus a real product gap — runtime handoff never engages the Xvfb auto-spawn — filed as #2764). The ship-time fix batch re-runs the gate lanes on this push.

Documentation

Post-ship doc sync (/document-release, commits bd4a721 + 3e3c723):

  • README.md — documented the persistent timeline Stop hook opt-out (setup re-registers the timeline Stop hook on every run with no config gate — --no-team doesn't persist #2677): ./setup --no-timeline-stop-hook, the GSTACK_TIMELINE_STOP_HOOK env var, and the timeline_stop_hook config key (flag > env > config; an explicit "no" removes a live registration and the choice survives upgrades).
  • BROWSER.mdbrowse stop against a dead daemon also reaps the headless Chromium child recorded in the state file, verified by start time + a Chromium-looking cmdline before any signal (browse: headless GPU process pegs ~800% CPU on macOS 26 / M5; --disable-gpu alone insufficient #2709); the stop command row says so too; the environment table gains CHROMIUM_PROFILE and GSTACK_DISABLE_GPU rows.
  • CONTRIBUTING.md — the day-to-day example now edits review/SKILL.md.tmpl (SKILL.md is generated) and regenerates; the OSV scanner row documents the explicit --config load (the filename is not auto-discovered) and the reasoned, expiring ignore contract.
  • CLAUDE.md + CONTRIBUTING.md — free-suite test count ~7,000 → ~8,700 (8,660 as of this wave).
  • Generated docsbun run gen:skill-docs re-run produced zero drift: SKILL.md files, llms.txt (55 skills / 76 browse commands), and the agents digest are all in sync with templates at HEAD.
  • CHANGELOG.md — the v1.78.0.0 entry is current through HEAD (absorbed-PR credits, fix-batch properties, numbers table); verified, not edited. VERSION v1.78.0.0 ↔ package.json 1.78.0 translation consistent.
  • TODOS.md — wave-deferral ledger already filed on-branch; no unmarked completions, no new TODO/FIXME comments in the diff.
  • Release artifacts — upgrade migration gstack-upgrade/migrations/v1.78.0.0.sh follows CONTRIBUTING's migration format.
  • Cross-model doc review (Codex, high effort) — 8 findings: 4 applied (the CONTRIBUTING/BROWSER items above), 2 already fixed by the sync commit, 2 flagged below without edits.

Documentation Debt

  • gen-skill-docs --link-root — reference in the CHANGELOG contributors section and the inline docblock only; the render-into-tmp-then-swap contract isn't in docs/TESTING_INTERNALS.md.
  • BROWSER.md/ARCHITECTURE.md state-file lifecycle prose doesn't enumerate the new chromiumPid/chromiumStartTime fields (reap behavior itself is now documented; field-level reference would live in the state-file docs).

Flagged for maintainer (review findings, deliberately not edited)

  • CHANGELOG v1.78.0.0 headline says "Both red weekly lanes are green again" while the PR's own eval notes say the periodic lane remains churn-red in its pre-wave shape (Periodic lane has never been green in its v1.77 shape — residual churn ledger post-v1.78 (bands, exited-class, known flakes) #2756 residual ledger). Narrative call on the headline's framing — CHANGELOG entries are clobber-protected, so no edit without maintainer say-so.
  • Codex claims the "~$4.35/run max" eval-cost figure in CLAUDE.md/CONTRIBUTING.md conflicts with this branch's gate spend; no in-repo receipt substantiates the figure it quoted, so the claim is unverified and the docs were left as-is.

No architecture diagram drift: ARCHITECTURE.md's diagram entities all survive this wave unrenamed.

TODOS

Residuals filed in TODOS.md ("v1.78 fix-wave deferrals"). Disposition drafts for the deferred/rejected PRs (#2707, #2704, #2750, #2749, #2670, #2695, #2729) are in .context/wave-dispositions/ pending maintainer review — nothing posted to contributors yet.

…US 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.

…ailed 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

…ges 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.

…nfig + 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.

…ions, 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).

The only non-dry-run --code-only child hits #1734's PATH-resolved

Wave-amended: goldens regenerated against the wave tree (author's golden commit 8e7a03c superseded)
…eady

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 5797d32 superseded); +2 tests
`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.
`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).

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.

…ne-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).

…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.

…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.
…aemon

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.

Wave polish on the #2690 absorption: the describe-scope mkdtemp left one
directory per run.

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

Wave-added coverage for the #2732 absorption: a 6-line fix with zero tests is
how the hardcoded path shipped in the first place. resolveChromiumProfile's
env behavior is already pinned in config.test.ts; this pins cli.ts's
delegation and forbids the hardcoded path from returning.

…val (#2727)

Wave-amended: test moved to browse/test/ (browse unit-test convention); trailing-semicolon normalization kept — it is load-bearing for the expression wrapper
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)
Wave-amended: all four writers unified on the env-var import pattern the PR already used in gstack-developer-profile (apostrophe-safe without CWD-dependent module resolution); import-shape pin updated
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.

Wave-amended: contributor's local-workaround docblock note removed; issue refs retargeted #2653 (closed by its author) -> #2724 (the live 887-staged-to-0-ingested report)
Wave-amended: seeding relocation re-applied to the composite action (v1.77 moved CI seeding out of the inline workflow steps the original commit edited); wiring tripwire re-pointed accordingly; stale marker comment updated
Follow-through on the #2748 absorption: existing installs answered the
continuous-checkpoint and model-overlay prompts with markers beside the
install; v1.78 reads them from GSTACK_HOME. Copy them once so nobody gets
re-prompted. Idempotent, non-fatal.

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').

challenge-mode initialized turn_completed_count but tested turn_failed via
'in dir()'; consult-mode initialized neither and rebuilt the counter with
a dir() conditional per event. Both parsers now init turn_completed_count
and turn_failed up front and use plain checks — same semantics, no
module-globals introspection.

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.

A leftover $INSTALL_DIR.bak from a crashed upgrade would make the mv nest
the live install inside it, and the failure-restore arm would 'restore'
the stale backup — possibly deleting the only good copy. The upgrade now
refuses to start and tells the user to inspect/salvage the backup.

--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
happened.

…nt warning

One shared _gitleaksWarned flag served two different messages: a 'machine
under load, retrying next file' warning early in a run permanently
silenced the later 'gitleaks not in PATH; secret scanning disabled'
warning — the user never learned scanning was off for good. Split into
per-message flags.

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.

…se docstring

--out-dir and --link-root shared near-identical inline parsing; one helper
now owns it. The rewriteSectionBase docstring said 'no-op when --out-dir
is unset' but the gate is the link root (which --link-root can set
independently) — it now describes the real behavior.

…disambiguateSlugs wiring

The #2724 disambiguateSlugs block was inserted between preparePages'
docblock and the function, orphaning the secret-scanning policy doc onto
the wrong symbol. Reordered. A call-site pin now asserts the prepare→stage
flow actually invokes disambiguateSlugs, so a refactor can't drop the call
while every unit test stays green.

…erage

The suite used a FIXED tmpdir name, so concurrent runs (sharded runner,
sibling worktrees) tore down each other's trees mid-flight — now a
per-run mkdtemp root with the apostrophe dir inside. gstack-telemetry-log
was the one bin named in the suite header with no test: it now must append
a real row under the hostile path with the credential span redacted
(<REDACTED-github.pat>) and the rest of the message preserved.

The only migration without a dedicated test. Covers copy-when-absent

SPAWNED_ESCAPE_SENTENCE's tightened wording had no pin: positive pins on
the explicit-declaration clause, negative pins on the retired v1.76 loose
parentheticals ('e.g. your dispatch prompt says', 'marks this session as
spawned'), and a drift guard that both hook directives embed the constant
verbatim.

…er tracks opener length

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.

Pins the >145KB truncation regression (process.exit before the pipe
drained): 900 MEDIUM findings -> 259KB JSON report through a sleep-first
POSIX consumer that holds the 64KiB kernel buffer full at child exit;
asserts complete parseable JSON with matching counts and exit 2, plus an
--auto-redact mirror (700 redactions, final sentinel byte arrives).
Harness proven red against a copy of the bin with process.exit restored.

Companion to the gen-skill-docs parsePathFlag extraction: the pin still

A hardcoded /usr/bin:/bin child PATH breaks spawn('bash') on the Windows
curated lane (spawn resolves against the CHILD env's PATH; no bash.exe
lives there). Hermeticity is carried by HOME/GSTACK_* overrides, not PATH.

…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.

…e 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.

"Both red weekly lanes are green again" overclaimed: OSV is verifiably
green (pinned scanner, frozen install, branch dispatch), but the periodic
lane keeps its pre-wave churn (#2756) — what this wave proves is that the

cross-model doc review; headline now leads with the user-visible outcome.
