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.

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

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.

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

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

a real row under the hostile path with the credential span redacted

The #2724 disambiguateSlugs block was inserted between preparePages'

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

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

rationale comment: caching a timeout for process lifetime is deliberate —
the memo dedupes the ~3 probes of one short-lived preamble process.

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

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

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

challenge-mode initialized turn_completed_count but tested turn_failed via

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

the detect/display greps share one hoisted _BROKEN_SIG regex (they had

isSingleParenOrIifeExpression accepted any tail after the initial group's

`(async()=>{await 1})().then(x=>x); console.log('done')` classified as a

readPidCmdline fell back to '' on darwin (no /proc), so the identity gate

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.

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

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
v1.77.0.0 scratch worktree.

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.

--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.

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
gen-skill-docs note that pointed users at relink now describes what relink
actually covers.

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).

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
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).

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