The 4G remount does not survive restarts; a reverted 64M shm made the
multi-tab browse handoff test fail consistently under suite concurrency
(observed live: two consecutive full-run failures, green in isolation,
green again after remounting). Same guarded arithmetic as the doctor body.

path.join built it with backslashes on Windows, so the wiring test's
string comparisons against setup and hosts/*.ts (which carry the
forward-slash literal) could never match there — windows-free-tests red.
path.join(root, DIGEST_RELPATH) at the write site normalizes fine.

CI exposed two wrong assumptions in the new temp-dirs tests, neither a
product bug:
- The remote-serving asymmetry test assumed a distinct os.tmpdir() lies
OUTSIDE TEMP_DIR, but the free-shard runner nests each child's TMPDIR
inside /tmp on CI — a file there is under TEMP_DIR, so serving it
remotely is legitimate. The test now pins the actual exfil boundary on
every topology (a cwd project file is locally readable, never remotely
servable) and branches the os.tmpdir() case on nested-vs-outside.
Reproduced locally with TMPDIR=/tmp/nested-tmp before fixing.
- The untrustable-TMPDIR subprocess probes set TMPDIR, which Windows
os.tmpdir() ignores (reads TEMP/TMP) — and on Windows TEMP_DIR is
DEFINED as os.tmpdir(), so the fixed+movable two-dir topology the guard
filters does not exist there. Probes now skip on Windows with that
rationale; the benign-TMPDIR assertion compares realpaths.
Verified under all three POSIX topologies: TMPDIR=$HOME/tmp (outside),
TMPDIR=/tmp/nested-tmp (CI shard shape), TMPDIR unset (identical).

- The ls-remote zero-heads warning no longer accuses an empty remote of
running a laundering shim.
- instructionTier.rulesFile now must equal the generator's DIGEST_RELPATH

TEMP_DIRS honors os.tmpdir() at daemon start; a daemon launched with
TMPDIR=/ would have trusted the whole filesystem for local path validation
for its lifetime. Subprocess pins cover /, $HOME, cwd-ancestor rejection and
that a benign distinct TMPDIR (the sandbox recipe's $HOME/tmp) stays honored.

- The /conductor/bin/git patch writes tmp-then-rename with a .orig backup —
a concurrently spawned git can never exec a truncated shim.
- Xvfb running-check looks for the :99 socket, not any-display pgrep.
- Xvfb install is dnf-gated so non-dnf distros degrade to a warning instead
of aborting the remaining fixes under set -eu.
- The bashrc /dev/fd restore uses sudo -n || true — no password prompt at
every shell start on non-passwordless machines.
- BASH_COMPAT=50 keeps heredoc bodies off the bash pipe window.

A failed digest regen warned and moved on — ship now instructs re-running
the generator and staging the digest with the bump (the freshness check
stays red otherwise). The 'no-op everywhere else' phrasing oversold safety:
the step now names what executes and why that is inside the envelope Step 5
already opened (the repo's own test suite).

The plan's metric order is diff-quality FIRST, but cells never ran the
fixtures' own run-tests.js, so a refusal, a broken implementation, and
working code were indistinguishable in aggregates (Codex adversarial catch).
Tasks with an oracle declare checkCmd; every cell records checks=pass|fail|none
in the report line and eval store. Selftest pins the oracle declarations and
that the planted bug fails its own check pre-fix.

The final gate offered B2 (respond to User Challenges) but the option
handler table omitted it, leaving accepted challenges with no amendment or

sharing D's 3-cycle cap.

Cross-model catch (Claude adversarial + Codex agreed): any diff author could

The cycle-2 additions pushed the python-patch and bashrc heredocs into the
512-65536B window test/heredoc-pipe-deadlock.test.ts guards (sh scripts get
no BASH_COMPAT escape hatch). Same content, tighter prose; the drift warning
now reuses the patch pattern variable instead of a second literal.

The selftest lived inside the paid skill-e2e-* file, so fixture-integrity
and plumbing pins executed weekly at best — a broken fixture would ship past
every gating check and be discovered when the periodic run burned money on a
dead instrument. Harness extracted to test/helpers/arm-benchmark-harness.ts,
selftest to test/arm-benchmark-selftest.test.ts (free suite). Touchfiles:
harness added to the three benchmark dep lists; the auq-repetition-cut-ab
tier comment now states the MANUAL re-run obligation honestly (periodic runs
force EVALS_ALL, so dep lists cannot auto-trigger it).

- Asserts $SOURCE_GSTACK_DIR/agents-digest path and forbids $(pwd)/agents-digest

- The /conductor/bin/git patch was a silent no-op if the shim's bytes drift

undo it.
- Test pins the guarded shm form (missing /dev/shm must not abort set -eu).

The originConfigured guard covered only the no-origin laundering case. With
origin configured (the normal Conductor worktree state), the laundering shim
makes a failed ls-remote exit 0 with empty stdout — read as 'the queue is
empty', the exact duplicate-allocation bug (#2545) one layer up. A reachable
remote always advertises at least its default branch, so an exit-0 zero-head
probe now falls back to local refs/remotes/origin with a laundering-specific
warning. Regression test shims git for both configurations.

The gate equated 'some failure attributed' with 'all failures attributed': a
shard with one attributed failure plus a headerless failure, an unhandled
error between tests, or a truncated run (no terminal summary) qualified for
retry — re-running only failingFiles and masking the rest as FLAKY-PASS,
re-opening the silent-truncation hole the strict classifier closes.
FreeShardOutcome now carries unattributedFailures; nonzero vetoes the retry.
Pins: mixed shard, truncated-with-attributed shard, empty-shard field values.

Review (security) caught the cycle-1 fix executing any repo's
scripts/gen-agents-digest.ts on plain 'write' — arbitrary code exec from a
hostile clone on a routine bump, contradicting the binary's own containment
posture. The regen still runs the TARGET repo's generator (a 'trusted' copy
beside the binary would false-red the freshness gate on version drift), but
only under the flag: /ship passes it deliberately, in a repo whose code the
operator already executes (its test suite). Plain write is side-effect-free
again. Also: uniform output shape (agentsDigest: null on the JSON-manifest
branch), a REAL generator round-trip test replacing the misnamed lockstep
check, and land-and-deploy's evidence gate gets the same digest allow-path
as ship so the two grading surfaces agree.

On healthy hosts the guarded and unguarded paths behave identically, so a
revert passes the suite; only a shim that makes 'git ls-remote' exit 0 with
empty output (the Conductor wrapper's observed behavior) exposes it. Pins
that the empty 'successful' probe is never trusted as an empty queue.

- The PRE arm read a branch-local SHA (3263fffe) that becomes unreachable on
fresh clones after the squash-merge; the pre-cut render is now a vendored
fixture.
- A judge failure on one side no longer coerces substance to 0 (which
fabricated DEGRADATION on POST-side failures and masked regressions on
PRE-side failures): null substance = inconclusive, format still gates.

- Harvest diffs against the recorded seed SHA (origin/main is movable by an
agent that commits AND pushes; a recorded SHA is not).
- Fixtures get a node_modules .gitignore and the git wrapper a 64MB
maxBuffer, so a vendored-dependency arm is scored instead of killing the
cell.
- The judge diff cap is a named constant with loud truncation (log +
judge_reasoning suffix).
- Judge prompt block markers carry a per-call random sentinel, so a diff
containing a faked closing marker cannot escape the data block.

The print-path-only guard now catches tee/install/rsync/dd/truncate, >>

agents-digest/gstack-AGENTS.md embeds VERSION in its first line and is

but nothing in the release path regenerated it — every version-bumping ship
of this repo would land red. write now spawns the repo's own generator when
present (agentsDigest true/false/null in the output JSON), and ship's
evidence gate allow-lists the digest alongside VERSION/package.json.

The merge kept a branch-local _sha256_hex helper; main's v1.72 landed the

Measured failure taxonomy for Vercel/Conductor sandboxes (missing /dev/fd,
64M /dev/shm, seccomp-supervisor access(2) EACCES under load, uid-1000
processes with FULL capabilities defeating chmod-denial tests, no X server,
no git identity, Conductor git-shim exit-code laundering) plus the

Without the guard, git DWIMs the literal 'origin' as an ssh host/path; on
hosts whose transport launders exit codes the probe 'succeeds' with zero
branches and the allocator silently sees an empty queue — the exact
duplicate-allocation failure (#2545) fetchGitClaimed exists to prevent.
git remote get-url origin gates the probe; absence falls through to the
existing local-refs path with its staleness warning.

resolve-user-slug and endpoint hashing exited 127 on Amazon Linux (shasum

Local path validation now accepts os.tmpdir() alongside the classic /tmp
(new TEMP_DIRS in platform.ts): on macOS os.tmpdir() is /var/folders/...,
and TMPDIR-honoring CI/sandbox environments point it elsewhere entirely —
both are legitimate scratch space. Remote file serving (TEMP_ONLY) stays
pinned to TEMP_DIR alone; no change to the exfil boundary.
commands.test.ts drops 41 hardcoded /tmp literals for a tmpp() helper on
os.tmpdir() (two message assertions now reference the same variable), and
path-validation's symlink-escape test targets /etc/hosts instead of
/etc/crontab — the target must EXIST for realpath to resolve the link (a
dangling target falls back to the link's own path and passes vacuously),
and /etc/crontab is absent on Amazon Linux.

GSTACK_FREE_JOBS overrides the computed shard count (the free runner's
analogue of the paid runner's EVALS_JOBS). On Vercel sandboxes, PID 1
installs a seccomp filter whose supervisor spuriously fails access(2) for
busy processes — measured: 200/200 git-init probes fail 'Cannot access work
tree: Permission denied' while the suite runs at 6 shards, 0/200 idle;
statx succeeds while access fails on the same path in the same process.
One serial mega-shard maximizes per-process pressure and fails too; 2
shards is the measured sweet spot.
GSTACK_FREE_RETRY_FLAKY=1 (default OFF — dev boxes should see flakes)
re-runs attributed failures once, serially, capped at 5 files; a clean
retry downgrades to a loud FLAKY-PASS naming the offenders, a repeat
failure stays red, timeouts and unattributed failures never retry.

* fix(browse): never chmod shared, symlinked, or foreign-owned dirs to 0700
restrictDirectoryPermissions unconditionally chmodded its target. On hosts
where the process holds CAP_FOWNER (Docker as root, CI sandboxes) that
chmod SUCCEEDS on root-owned /tmp whenever a state file is configured
there (BROWSE_STATE_FILE=/tmp/x.json derives stateDir=/tmp), and a 0700
/tmp breaks access(2)-based checks machine-wide for every other process.
The POSIX branch now refuses shared sticky dirs, world-writable mounts
under root, foreign-owned dirs, and symlinked state dirs; refusals warn
once per process instead of failing silent; owned-but-unreadable dirs
keep their chmod self-repair; and the check-then-act race is closed with
fd-anchored O_NOFOLLOW + fstat/fchmod on a single inode.
Regression tests cover the sticky-dir, foreign-uid, mkdirSecure-reapply,
and symlinked-dir shapes.
* fix: hash with sha256sum before shasum on Linux (config slugs + setup verify)
shasum is perl/macOS; coreutils-only Linux ships sha256sum. Two call
sites hard-coded shasum: gstack-config's sha8_of/sha16 (so
resolve-user-slug exited 127 for any Linux user with a git email, the
Layer-3 fallback) and the generated bun-installer checksum snippet in
the browse/qa NEEDS_SETUP flow (spurious "checksum mismatch" on the
same distros). Both now resolve sha256sum first and fall back to
shasum -a 256.
New shim-PATH tests pin BOTH hasher branches of sha8_of to a known
vector and cover the sha8->sha16 collision escalation end to end.
* feat(contract): Aside is the recommended driver for third-party web actions
The Third-Party Web Actions contract (ship, spec, office-hours,
land-and-deploy, setup-deploy) now names the Aside AI browser as the
recommended driver: it acts across the user's real logged-in sessions,
which is what vendor-dashboard moments need. Supersedes the v1.65.0.0
de-Aside stance by explicit user directive (2026-08-27).
Detection is a runtime probe (command -v + aside --version under a
portable gtimeout/timeout/bare guard; nonzero exit = not detected).
Consent options render per detection state with Aside recommended and
the first-party stack ($B headed + handoff, GStack Browser) as the
universal fallback. Absent on macOS, the contract mentions the
aside.com download (macOS 15+) once per task; gstack never runs an
installer and binary presence is never consent. Drive discipline:
step-wise over whole-task delegation, vendor confirm mode on, vendor
skill/--help text scoped to operational syntax only, secrets minimized
(autofill / human-used copy buttons), Apple credential creation never a
drive target in any skill, failure path quotes redacted errors and
falls back only with fresh consent.
test/third-party-actions.test.ts pins every load-bearing sentence (21
tests) plus repo-wide tripwires: an aside command allowlist
(--version/--help only, code spans AND prose) and a ban on Aside
installer invocations across all generated docs. Budget ratchet
fixture and carve skeleton ceilings refreshed in this commit per the
ratchet protocol.
* chore: regenerate remaining browse-setup snippet consumers
The sha256sum-first checksum fallback in the generated NEEDS_SETUP
snippet renders into every browse-consuming skill, not just browse/qa.
Mechanical regen of the other ten consumers; no template changes here.
* test: consent-gate E2E suite + functional fs-capability probes
Five hermetic gate-tier E2E cases (tpa-present / absent-linux / broken /
absent-darwin / apple-ban) drive the real contract section through
claude -p with PATH shims for aside and uname; the absent cases filter
any REAL aside binary out of the child PATH and assert absence with
Bun.which before spawning, so dev machines cannot leak into detection.
Registered per-case in E2E_TOUCHFILES/E2E_TIERS with template-level
deps (ship/SKILL.md.tmpl, gen-skill-docs.ts) and added to the evals.yml
matrix with tier: gate. eval:bg:periodic's detach timeout rises to
36000s for the grown periodic shard census (floor-enforced by
test/eval-detach-timeout-floor.test.ts); CLAUDE.md doc updated to match.
test/helpers/fs-caps.ts adds canRevokeWrites/canRevokeReads functional
probes; 13 chmod-based tests swap their uid-0-only guards for the
probes so suites skip honestly on CAP_DAC_OVERRIDE containers (this
sandbox: uid 1000 with full caps) instead of asserting revocations the
kernel ignores. path-validation's symlink test targets /etc/passwd
(exists everywhere; /etc/crontab is absent on Amazon Linux).
* docs: file the Aside follow-ups in TODOS
Phase-2 QA logged-in-evidence path (P3), a hostile-vendor-skill E2E for
the contract's override sentence (P2), and fd-anchoring the file-level
permission writes to match the directory hardening (P3).

* fix(test): gate the symlink-refusal test to POSIX and drop the umask assumption
The symlink regression test exercised the POSIX O_NOFOLLOW branch but ran
on Windows, where restrictDirectoryPermissions takes the icacls branch and
stat has no POSIX modes (0o666 always) — windows-free-tests failed on
mode 493 vs 438. Early-return on win32 like every sibling test in the
file, and assert the target's mode is UNCHANGED (captured post-mkdir)
instead of hardcoding 0o755, which a strict umask would also break.
