fix(benchmark): validate --timeout-ms as a positive integer
gstack-model-benchmark fed --timeout-ms straight through parseInt, so
"abc" became NaN and "0"/"-1" passed through — a NaN or non-positive
timeout silently disables the per-provider watchdog. Reject anything
that isn't a positive (optionally +-prefixed) safe integer with a clear
error and exit 1.

Closes #1726.

security(browse): drop .svg from the load-html extension allowlist
SVG is a script-capable format (inline <script>, event handlers, foreign
objects), so allowing it through load-html's HTML allowlist let a local
.svg execute script in the browse session context. The allowlist is now
.html/.htm/.xhtml only; regression test asserts .svg is rejected.

fix(paths): shell-quote gstack-paths output so eval round-trips values
gstack-paths emitted bare KEY=VALUE lines, so the documented
eval "$(gstack-paths)" re-parsed the values: backslashes were eaten as
escapes (Windows $TMP C:\Users\... became C:Users...) and a space
word-split the assignment, leaving the variable empty. Emit each value
with printf %q so eval round-trips byte-for-byte; plain POSIX paths are
unchanged. Round-trip regression tests cover backslashes, spaces, and
embedded quotes.

Closes #2374.

fix(browse): surface non-EEXIST errors in acquireServerLock instead of masking them
acquireServerLock caught every open failure as if the lock were held:
EACCES/EROFS/ENOENT surfaced as phantom "another process holds the lock"
(null return, no diagnostics), and a failed stale-lock read or unlink was
swallowed the same way. Each failure class now logs a coded, pathed
diagnostic: non-EEXIST open errors, holder-PID read errors (ENOENT retries
the acquire — the holder released between open and read), and stale-lock
unlink errors. Four-case unit test included.

Closes #1084.

fix(telemetry): ingest keeps error_message/failed_step instead of dropping them
The telemetry_events columns exist and bin/gstack-telemetry-log already
sends error_message + failed_step, but the Supabase ingest function dropped
both fields on insert — every error report arrived with no message and no
failing step. Map them through with the same bounded-length sanitization as
error_class (500/100 chars). The completion-status resolver now also passes
--error-message/--failed-step in the generated skill telemetry block, with
instructions to leave them empty on success.

Resolver only for the template side; generated SKILL.md files regenerate
from this source in the docs lane.

fix(browse): daemon resilience on loaded machines — Bun conn errors, stop/restart flush, startup + git-root budgets
Four load-sensitivity fixes in the daemon lifecycle:

- sendCommand only recognized Node's ECONNREFUSED/ECONNRESET; the compiled
  CLI runs on Bun, which reports 'ConnectionRefused'/'ConnectionClosed'
  ("Unable to connect..."), so daemon crashes leaked the raw error and
  exited 1 instead of entering the busy-check/restart path. Match both.
- stop/restart called shutdown() inline, which exits before the HTTP
  response flushes — the CLI saw a dropped socket (and would now
  crash-retry a fresh daemon just to stop it). Defer shutdown ~100ms so
  the 200 lands first.
- Non-CI POSIX startup budget raised 8s -> 15s (cold Chromium measured
  ~5.7s at load avg 10; load 12+ blew the old budget while the detached
  daemon was still booting).
- getGitRoot's 2s git rev-parse timeout returned null under load (6.3s
  spikes measured), scattering state files across cwds into split-brain
  daemons. Raise to 8s, still bounded.

fix(browse): recover a late-healthy detached daemon instead of a false "Server failed to start"
startServer spawns the daemon detached + unref'd, then polls health for a
fixed budget. On a loaded machine the budget can elapse in the gap between
the loop's last tick and the daemon becoming ready — the CLI reported
"Server failed to start within Ns" while the very next `browse status`
showed a healthy server. Add a final readState()+isServerHealthy() re-check
before the timeout throw, and make the budget env-overridable via
BROWSE_START_TIMEOUT (BROWSE_* tunable convention). Structural + behavioral
tests pin both invariants.

A title that was nothing but a version ("v1.2.3" — the form ship uses for
version-only bumps) matched neither the "v<NEW_VERSION> " literal case nor

fix(resolvers): stop env-var hosts from doubling $HOME in the binary fallback path
The browse/design/make-pdf setup resolvers built the fallback binary path as
"$HOME" + dir.replace(/^~/, ''), which is only correct for ~-rooted dirs.
Env-var hosts carry an absolute $GSTACK_* dir, so the generated fallback

env-var dirs through untouched; all five call sites route through it.

fix(codex): sandbox the review path, fail the gate closed, order timeouts wrapper-first
Closes #2496, #2524, #2477 — three defects in the class "a guard that
reports success while doing nothing", all in codex/SKILL.md.tmpl:

(a) Review sandbox. The default `codex review` path was the only codex call
with no sandbox override, inheriting ~/.codex/config.toml's default — write
access on a trusted project — while Important Rules claimed read-only.
Top-level `codex review` has no -s/--sandbox flag (verified on 0.147.0), so
the invocation now pins `-c 'sandbox_mode="read-only"'`, the same form the
consult-resume path already uses.

(b) Fail-closed verdict gate. The old rule ("no [P1] found → PASS") could
not fail on the default path: native `codex review` output carries no
bracketed tags, and a non-zero exit, expired auth, timeout, or empty result
also contains no [P1] — all read as PASS. The gate is now an ordered,
fail-closed check: non-zero exit → FAIL; empty output → FAIL; [P0]/[P1]
(bracketed or codex's native labels) → FAIL with count; NO severity tags at
all → FAIL requiring a human read; PASS is only reachable through the
explicit tagged-advisory-only branch. [P0] is recognized as blocking, and
the review-log findings count includes it.

(c) Bash gate above the wrapper. Step 2A instructed `timeout: 300000` under
a 330s wrapper, and Challenge's 300s gate sat under a 600s wrapper — the
harness killed the call before the wrapper could emit its diagnosable
exit-124 message. Every Bash gate now sits strictly ABOVE its wrapper:
360000 over the 330s review wrapper, 660000 over the 600s challenge/consult
wrappers, with the ordering rationale stated at each site.

Also from #2477/#2524: a new Error Handling entry for the model-entitlement
400 ("The '<model>' model is not supported...") pointing at the `model =`
pin and `[notice.model_migrations]` in ~/.codex/config.toml and saying
exactly which override to retry with (-m for exec-based modes,
`-c model="..."` for review mode, which rejects -m); the Model & Reasoning
section no longer documents `-m` for `/codex review`.

Static assertions in test/codex-hardening.test.ts pin (a)-(c) across both
the .tmpl and the generated SKILL.md: every scoped review invocation carries
sandbox_mode="read-only" and never -s; the default-PASS sentence is banned
and the fail-closed branches are present; and per-section, every Bash
`timeout: N` is strictly greater than every wrapper budget, with 2A/2B/2C
all required to be inspected. Generated SKILL.md regenerated via
gen:skill-docs in this commit.

fix(review,ship): run the codex diff passes under the timeout wrapper (#1036)
The `_gstack_codex_timeout_wrapper` added in #1056 was wired into
codex/SKILL.md but never into the /review and /ship diff passes, which kept
running under a bare 5-minute Bash gate. An unwrapped stall returns no exit
code and no output, which downstream reads as "Codex reviewed and found
nothing" — a truncated pass silently became a clean bill. Measured on
codex-cli 0.145.0: a pass was killed at 287s of a 300s budget mid-tool-call,
and the same prompt completed in 336s.

Both passes in scripts/resolvers/review.ts (adversarial `codex exec` and the
structured `codex review --base` pass) now re-source gstack-codex-probe and
run under `_gstack_codex_timeout_wrapper 540`, with the Bash tool gate raised
to 600000 ms so the wrapper fires FIRST and a stall surfaces as a diagnosable
exit 124. The timeout guidance now says a timed-out pass is MISSING COVERAGE,
not a clean result, and points at the run's rollout log under
~/.codex/sessions/ for partial output. The stale "timeout doesn't exist on
macOS" claim is gone — the wrapper resolves gtimeout, then timeout, then runs
unwrapped, so it is safe without coreutils.

Static guards in test/codex-hardening.test.ts pin all three sites (resolver,
review/SKILL.md, ship/sections/adversarial.md): both calls wrapped, wrapper
budget strictly under the Bash gate, and no reappearance of the macOS claim
that steered these call sites away from the wrapper in the first place. The
Claude-output path guard in test/gen-skill-docs.test.ts now scrubs
~/.codex/sessions/ (a user-facing Codex CLI path, same class as the
~/.codex/logs/ exemption) before banning Codex host paths. Generated files
regenerated via gen:skill-docs; factory golden refreshed.

fix(codex,review,ship): scope codex review with an explicit --base flag, never prompt text
`codex review` takes its scope ONLY from --base/--commit/--uncommitted. The
positional [PROMPT] is mutually exclusive with all three, and a prompt-only
`codex review "<text>"` silently falls back to the uncommitted working-tree
scope (verified on 0.144.1: it runs `git status --short; git diff` and
reviews that) — so the previous prompt-based scoping produced a
confidently-worded review of the WRONG changes and read "no changes" on a
clean tree. Every diff pass now invokes `codex review --base <base>` with no
prompt argument: /codex Step 2A default path, the /review structured pass,
and the /ship adversarial-section pass (all via scripts/resolvers/review.ts).

Custom review instructions keep their own `codex exec` path (the CLI rejects
prompt + scope flag together), with the filesystem boundary preserved there.
Two new Error Handling entries teach the failure shapes: the argv-parse
error, and the "review says no changes on a branch full of changes" symptom.

Tests updated to pin the new invariant instead of banning the fix: the old
assertions required the diff range in prompt text and banned the
`--base <base> -c '...'` substring, which the correct scoped form contains.
Also deletes test/fixtures/golden-ship-claude.md — a 2,565-line orphaned
fixture referenced by zero tests (the live goldens are in
test/fixtures/golden/, compared by test/host-config.test.ts); the factory
golden is refreshed from the regenerated output. Generated SKILL.md files

fix(mktemp): move the X-run to the end of every temp-file template (BSD/busybox safe)
BSD mktemp (macOS) does not substitute an X-run that has a suffix after it:
`mktemp "$TMP_ROOT/codex-err-XXXXXX.txt"` creates a LITERAL
codex-err-XXXXXX.txt on the first call (exit 0) and every later call fails
with `mkstemp failed: File exists` — so /codex breaks from the SECOND run on
every Mac, masquerading as a model stall. busybox mktemp (Alpine) rejects the
template on the first run. Fixes #2091, #2370.

Union of both community fixes, compared at the diff level:
- PR #2372: all 11 source sites with a suffix after the X-run — codex
  SKILL.md.tmpl (5), claude SKILL.md.tmpl (3), bin/gstack-developer-profile
  (2, suffix folded into the prefix: .json.tmp.XXXXXX), and the office-hours
  codex pass in scripts/resolvers/review.ts (1).
- PR #2103: the second half of #2091 — bin/gstack-paths now strips the
  trailing slash from TMP_ROOT at the source (macOS $TMPDIR ends in `/`),
  plus runtime tests pinning that normalization.

New repo-wide tripwire in test/regression-issue2091-bsd-mktemp.test.ts:
every .tmpl, every SKILL.md, and every scripts/resolvers/*.ts is swept —
no mktemp template may carry a suffix after the X-run, with a self-test so
the detector can't be quietly blinded. Generated SKILL.md files regenerated
via gen:skill-docs in this commit.

ci(windows): curate the fix-wave regression tests into the windows-latest run
The windows-free-tests curated set is derived (POSIX-fragility regex scan
+ explicit deny list), and two of this wave's Windows regression files
were auto-excluded on false-positive pattern hits:

- browse/test/file-permissions.test.ts tripped the POSIX-mode-bitmask
  pattern, but every `mode & 0o777` assertion is platform-guarded — and
  the file carries the win32-only icacls-by-SID regression tests, which
  can only ever execute on windows-latest.
- browse/test/terminal-agent-owner-watchdog.test.ts tripped the
  spawn(['bun','run',...]) pattern whose reason is the Playwright-bound
  browse server; it actually spawns terminal-agent.ts (fs/path/crypto +
  local helpers only, no Playwright at module scope), and the owner-PID
  orphan leak it pins was reported on Windows (#2019).

Adds a KNOWN_WINDOWS_SAFE force-include list (mirror of
KNOWN_WINDOWS_INCOMPATIBLE, each entry carrying its false-positive
rationale) consulted before the pattern scan, and makes the
owner-watchdog test's throwaway owner process Windows-portable
(process.execPath instead of `sleep`, which a bare runner may not have).

The wave's other new files need no wiring: process-liveness-windows and
the bun-polyfill windowsHide/exited tests pass curation automatically;
setup-runtime-lib-command self-skips on win32 by design (its Windows
branch is exercised by simulating IS_WINDOWS=1 under bash), so
force-including it would add a permanently-skipped file.

fix(setup): ship supabase/config.sh with every host runtime root
Distinct from the lib/-beside-bin/ defect: gstack-telemetry-sync,
gstack-update-check, gstack-security-dashboard and
gstack-community-dashboard all source $GSTACK_DIR/supabase/config.sh to
resolve GSTACK_SUPABASE_URL, where GSTACK_DIR is the installed root
(parent of bin/). The [ -f ... ] guard means a root without the file
degrades SILENTLY — telemetry and update checks just stop resolving the
project URL on non-Claude installs. Closes #2215.

setup now links supabase/config.sh (file-level on purpose — migrations/
and functions/ are dev-only) via _link_or_copy at all five host-install
sites: the PR's four (Codex, Factory, OpenCode runtime roots + the Kiro
block) plus the .agents sidecar, whose bin/ resolves the same relative
path and which the PR predates covering.

The runtime-root test now asserts supabase/config.sh is present in
every built root, on both the symlink and Windows-copy branches.

fix(setup): link lib/ beside bin/ at all five host-install sites
bin/ scripts import shared modules via ../lib (gstack-learnings-log →
lib/jsonl-store.ts is the reported case), so any runtime root that
exposes bin/ without lib/ breaks 13 bin/ commands — learnings-log,
decision-log, telemetry and friends fail with "Cannot find module
.../lib/jsonl-store.ts" on every non-Claude install, silently from the
skills' perspective.

All five host-install sites now carry lib/ next to bin/, each through
the existing _link_or_copy helper (never raw ln — the static invariant
in test/setup-windows-fallback.test.ts enforces this):

- .agents sidecar (create_agents_sidecar asset loop)
- Codex runtime root (create_codex_runtime_root)
- Factory runtime root (create_factory_runtime_root)
- OpenCode runtime root (create_opencode_runtime_root)
- Kiro install block

New test/setup-runtime-lib-command.test.ts executes the real setup shell
for each root in a sandbox (both the symlink branch and the Windows copy
branch of _link_or_copy) and runs gstack-learnings-log end-to-end from
the installed root, asserting the learning lands in
~/.gstack/projects/<slug>/learnings.jsonl — plus a negative control
proving a bin-without-lib root fails exactly the way the bug report did.
gen-skill-docs.test.ts's setup-validation block pins the lib link at
every site. Cross-checked against PRs #2433, #2410 and #2198: all three
cover subsets of these sites; nothing they fix is missing here.

fix(setup): BROWSE_BIN carries the .exe suffix on Windows
On Windows, `bun build --compile` emits browse.exe, but setup's
BROWSE_BIN pointed at the suffixless path — so the post-build gate
(`[ ! -x "$BROWSE_BIN" ]` → "browse binary missing") could never pass on
Windows even after a fully successful build, while the build step itself
reported success. Closes #2291.

Applied the PR's override after the IS_WINDOWS detection, and also to
the second BROWSE_BIN assignment the PR predates: the direct-Codex-
install migration path re-derives BROWSE_BIN from the migrated dir and
would otherwise drop the suffix again on Windows.

fix(windows): give the bun-polyfill spawn shim a real `exited` promise
Bun.spawn exposes `proc.exited` as a Promise resolving to the exit code.
The Node fallback shim (dist/bun-polyfill.cjs) returned no such field, so
every `await proc.exited` on the Windows path resolved instantly to
undefined — the Windows cookie picker (cookie-import-browser.ts races
proc.exited at three sites) read stdout before the child produced it and
silent-failed; browser-skill-commands and terminal-agent hit the same
class.

The shim now:
- drains stdout/stderr eagerly into capped in-memory buffers (Node's
  Readables are pull-based; without draining, a child writing past the
  OS pipe buffer blocks in write() and 'exit' never fires), replaying
  them as fresh single-shot Web ReadableStreams so reads work before or
  after awaiting exit;
- caps the buffer at 16 MB (GSTACK_SPAWN_MAX_BUFFER to override), still
  draining past the cap so a runaway child can't wedge or OOM;
- resolves `exited` with Bun-matching codes (exit code, 128+signal, 1 on
  spawn error) after both pipes finish, and resolves on 'error' too —
  Node fires 'error' without 'exit' when the binary is missing, which
  otherwise hangs the await forever.

Six tests pin exit codes, the read-after-exit ordering, spawn-failure
resolution, the buffer cap, and the large-output drain. Adapted to the
current test file (require path goes through the requirePath variable
from the windowsHide commit), and the 1 MB drain test's child now exits
in the write callback — on modern Node a pipe write past the OS buffer
is async and process.exit() straight after write() truncates at ~64 KB
even with a live reader, which fails the test for reasons unrelated to
the shim.

fix(terminal-agent): tie agent lifetime to its owning browse server PID
The terminal agent is intentionally detached so it survives the
short-lived CLI launcher, but its real owner is the persistent browse
server. If that server crashed or was killed before running normal
shutdown, the agent was adopted by PID 1 and lived forever (#2019).

spawnTerminalAgent now requires an ownerPid and exports it to the agent
as BROWSE_OWNER_PID; all three spawn sites pass the server PID (cli.ts
cold-start, cli.ts supervisor respawn, server.ts watchdog). The agent
polls the owner with signal 0 every 15s (GSTACK_TERMINAL_OWNER_WATCHDOG_MS
to tune) on an unref'd timer and, when the owner disappears, exits
through the SAME cleanup path as an intentional SIGTERM shutdown — now
re-entrancy-guarded and also removing the terminal-internal-token file
alongside the port file and agent record.

Runtime test spawns a real agent tied to a throwaway owner process,
kills the owner, and asserts the agent exits and its discovery files
(terminal-agent-pid, terminal-port) are gone.

Reconciled with the watchdog commit's spawnTerminalAgent contract test
(process-liveness-windows.test.ts now passes ownerPid and pins the
BROWSE_OWNER_PID env forwarding).

Closes #2019.

fix(watchdog): signal-0 liveness, tick-scaled respawn guard, windowsHide
Three-bug chain behind the Windows terminal-agent leak (console window
strobing every 60s, one orphaned agent per watchdog tick until the box
ran out of committable memory):

1. isProcessAlive shelled out to `tasklist /FI "PID eq <pid>"` on Windows
   with a 3s timeout. A Bun.spawnSync that hits its timeout still RETURNS
   with partial stdout, so the `.includes()` PID match read a LIVE agent
   as dead — killAgentByRecord skipped the kill, the watchdog respawned
   around the survivor, and every orphan slowed the next tasklist enough
   to produce the next false negative. Now: `process.kill(pid, 0)` on
   every platform (Node and Bun both map signal 0 to an OpenProcess
   existence check on Windows), with EPERM counted as alive. No
   subprocess, no timeout, no console window.

2. The respawn circuit-breaker was mathematically unreachable — verified
   in this tree: RESPAWN_GUARD_WINDOW_MS was a fixed 60_000 against a
   60_000ms default tick, and each tick pushes at most one respawn
   timestamp, so three pushes span ~120s and can never coexist inside a
   60s window (eviction is strict `>`, and setInterval drift plus
   per-tick work always ages the prior entry past the boundary). The
   guard could not fire at the default tick rate and a steady
   one-per-tick leak ran unbounded. The window now scales with the tick:
   max(60_000, tick * (RESPAWN_GUARD_MAX + 2)), so "3 crashes in quick
   succession → stop" holds at any tick value.

3. The tasklist probe popped a visible console per tick (no windowsHide).
   Removing the shell-out kills that site; the agent-spawn site itself
   already passes windowsHide: true (landed with the bun-polyfill
   windowsHide commit — PR #2414's terminal-agent-control.ts hunk is
   reconciled there rather than duplicated).

New browse/test/process-liveness-windows.test.ts pins all three: no
subprocess from the probe, a static tripwire against reintroducing
`tasklist` + `PID eq` liveness checks in src/, the spawnTerminalAgent
windowsHide + stdio contract, and the window-derived-from-tick
arithmetic. terminal-agent-watchdog.test.ts test 4 now pins the
window/tick relationship instead of the fixed literal that let this
ship. Also converts `new URL(import.meta.url).pathname` to
`import.meta.path` across the static-grep tests it touches — the
pathname form yields /C:/... on Windows and breaks path.resolve.

fix(windows): forward windowsHide through the bun-polyfill spawn shims
windowsHide is the one spawn option where Node's default is the opposite
of Bun's: Node shows the child's console window, Bun.spawn hides it.
The polyfill's spawn and spawnSync shims dropped the option entirely, so
the Node fallback path (dist/bun-polyfill.cjs) silently inverted the
behavior on the one platform the shim exists to serve — every watchdog
respawn of the terminal agent popped a visible bun.exe console window.

Three sites fixed:
- Bun.spawnSync shim: forwards windowsHide with Bun-matching default true
- Bun.spawn shim: same (stdio:'ignore' silences output but does NOT
  suppress the console window on Windows)
- spawnTerminalAgent in terminal-agent-control.ts: explicit
  windowsHide: true, so the Node fallback path behaves like Bun-native

An explicit windowsHide: false is honored at both shims. Three focused
tests pin the default-true, default-true-sync, and explicit-false paths
by intercepting child_process in a subprocess; the test file's require
path now uses forward slashes so it survives interpolation into a JS
string literal on Windows.

Supersedes PRs #2523, #2294 and #2290, which each covered a subset of
these sites.

fix(windows): grant icacls ACEs by *SID, not unqualified username
An unqualified username handed to icacls is ambiguous: on a machine whose
hostname equals the username (a common Windows setup), it resolves to the
MACHINE account instead of the user. Combined with /inheritance:r, that
leaves ~/.gstack with a single ACE matching nobody — the process that just
"secured" the directory locks itself out, and icacls still reports success.

Both icacls sites in the repo (restrictFilePermissions and
restrictDirectoryPermissions in browse/src/file-permissions.ts — the only
icacls call sites; setup has none) now grant via icacls' literal-SID form
`*<SID>`, resolved once per process from System32\whoami.exe (pinned to
System32 because a bare `whoami` under a bash-flavoured PATH picks up the
MSYS build, which rejects /user). Fallback when the SID can't be resolved
is the domain-qualified `USERDOMAIN\username` name, which is unambiguous
where the bare username was not.

Windows-only regression tests assert the hardened directory stays usable
by the calling process (readdir + write), which is exactly the check that
a not-toThrow assertion sailed past before.
