448e148058 fix(#2455): abort remaining chunks when one hits the per-chunk timeout (#2465)
The per-chunk timeout exists so a bad chunk fails loudly 'rather than
silently burn the job's wall-clock budget until the CI runner cancels the
whole job' (run-tests.cjs:633-637). The control flow defeated that: after a
timeout kill the loop fell through to the next chunk. Since the timeout
(600000ms) is half the 20m job cap and a healthy Windows full pass is
~11m42s, continuing after a timeout can essentially never finish.

Observed on run 29749380190 (windows shard 2/3): chunk 1/5 was killed at
exactly 600s, the loop pressed on through chunks 2-4, and the job was
cancelled mid-chunk-5 at the 20m wall. The failure surfaced as
'##[error]The operation was canceled.' — the timeout diagnostic ended up
~38,000 log lines from the end and 'gh run view --log-failed' returned
nothing, making the real cause very hard to find.

Abort the remaining chunks on a timeout so the diagnostic survives as the
visible failure. Ordinary test failures still run every chunk, so the
operator keeps seeing all failures in one pass.

Fixes #2455

953b8043ea fix(#2456): weight test chunks by measured cost and pack with LPT (#2463)
* fix(#2456): weight test chunks by measured cost and pack with LPT

scripts/run-tests.cjs guessed each test file's cost from its filename
(basename matching /^(?:install|codex-)/ scored 12, everything else 1).
Measured durations show that guess is wrong in both directions:
installer-migration-authoring.test.cjs scored 12 while running ~0.1s, and
the two most expensive files in the suite both scored 1 —
run-tests-harness.test.cjs never matched the prefix, and
release-tarball-smoke.install.test.cjs was missed because the regex is
anchored to the START of the basename.

Chunks were therefore balanced by file COUNT, not cost. On the real
shard 2/3 the two heaviest files packed into the SAME chunk, leaving the
slowest chunk 2.8x the lightest and sitting near the 600s per-chunk
timeout while other chunks idled.

Weight each file by its measured duration from a checked-in, regenerable
timings table and pack with LPT (heaviest first, into the lightest
chunk). On the same shard this drops the slowest chunk from 383s to 238s
and the imbalance from 2.79x to 1.00x, and separates the two heavy files.

Timings are advisory, never gated: an unknown file falls back to the
table's median weight, a missing or corrupt table falls back to uniform
weight, and a count-based floor guarantees the packer never produces
fewer chunks than plain count-based packing would.

Closes #2456

* fix(#2456): harden chunk packing against degenerate knobs and table keys

Follow-up hardening found while reviewing the packer, fixed inline.

The chunk knobs are read from the environment with Number(), so a typo
(RUN_TESTS_MAX_FILES_PER_CHUNK=abc) yields NaN and an explicit 0 yields
0. Both flow into the new chunk-count arithmetic: NaN made Math.ceil
return NaN, Array.from({length: NaN}) produce zero bins, and packChunks'
retry loop spin forever — a hung CI job with no output. Zero made the
count Infinity and threw RangeError: Invalid array length. The previous
count-based packer degraded to a single chunk instead, so this was a
regression introduced by the LPT rewrite.

Normalize the knobs at the environment boundary (positiveNumberEnv:
anything not a positive finite number falls back to the default) and
guard packChunks itself, since it is exported and cannot assume its
caller normalized. Non-finite weights from an arbitrary weightOf are
clamped too. RUN_TESTS_CHUNK_TIMEOUT_MS gets the same treatment.

Also resolve timing-table lookups with Object.hasOwn: the table is
JSON-parsed, so a bare index would walk the prototype chain and return a
function for a file named constructor.test.cjs or toString.test.cjs.
The typeof guard already rejected that, but the lookup now resolves
correctly rather than relying on the downstream check.

* fix(#2456): correct prototype-lookup rationale and guard generator keys

Two findings from independent security review, fixed inline.

The makeFileWeigher comment claimed a bare table lookup "would return a
FUNCTION for a file named constructor.test.cjs". That premise is false:
basename('constructor.test.cjs') is 'constructor.test.cjs', which is not
an Object.prototype key, and walkTestFiles only ever collects *.test.cjs.
The prototype chain was never reachable from a real selection, and the
existing typeof guard already rejected the function it would return, so
Object.hasOwn is defense-in-depth rather than a behavior change. The
comment now says that instead of asserting something untrue.

The accompanying test inherited the same false premise: it fed
constructor.test.cjs and asserted a median fallback that would have held
with or without the guard, so it passed for a reason unrelated to what
it claimed to prove. It now uses BARE keys (constructor, toString,
valueOf, hasOwnProperty, __proto__) — the only inputs that actually
resolve on Object.prototype — and asserts the real exported contract:
any key absent from the table weighs the median, never a function.

gen-test-timings.cjs built its output object by computed-key assignment
from basenames taken out of a reporter stream it does not control — the
js/prototype-polluting-assignment shape, and this repo has a CodeQL
barrier for exactly that pattern. It was not exploitable (the value is
always a rounded number, so the __proto__ setter is a silent no-op), but
it silently DROPPED such an entry rather than reporting it. Validate every
key against a test-basename pattern and fail loudly instead, and build
the table with a null prototype.

* fix(#2456): replace tautological chunking tests and clamp chunk count

Six findings from independent correctness review, all reproduced and
fixed inline.

The two subprocess tests written to carry the #2088 guarantee forward
were tautological: every seeded file weighed exactly 1, so both passed
under the OLD prefix-heuristic packer and with the timings file deleted
entirely. Neither could fail for the reason it existed. Both are rebuilt
so the old algorithm produces a different packing and the assertion goes
red: the spread test now uses three expensive files named so the old
heuristic scored them 1 alongside three trivial `install-`-prefixed
files it scored 12 — inverted from real cost, giving {2,2,1,1} under the
old packer versus {2,2,2} under measured weights. The companion test
covers the other direction: four trivial `install-` files the old
heuristic split into four single-file chunks now stay in one.

packChunks clamped the chunk count from below but not above, so a
legitimate but tiny budget (RUN_TESTS_MAX_FILES_PER_CHUNK=1e-9, which
positiveNumberEnv accepts) asked for 637,000,000,000 bins and threw
RangeError. More chunks than files is never useful; the count now clamps
at one file per chunk.

The generator's basename-collision guard compared full dirnames, so two
OS lanes reporting the same file under different container roots
(/work/tests vs C:/work/tests) flagged every shared basename as a
collision — on the script's own documented multi-lane usage. Detection is
now scoped per stream, where the root is constant; a genuine same-lane
collision is still caught.

Also: the LPT tie-break compared raw paths, so a path separator (0x2F vs
0x5C) could order a subdir file differently per platform, contradicting
the documented byte-identical guarantee — it now normalizes separators.
loadTestTimings now honors schema_version instead of writing it and
never reading it, falling back to uniform weight on an unknown version.
A comment claiming an all-uniform suite "chunks exactly as it did
before" was false and contradicted by this PR's own test: the chunk
count is preserved, the composition is not. And the missing-table test
created a temp dir it never cleaned up, for a path that only needed to
not exist.

8b99f4f3c3 fix(#2088): weight install-heavy test files so they spread across chunks
The targeted CI lane runs changed files UNSHARDED; #2088 touched 13 install-heavy
test files that all landed in one chunk, blowing the 600s per-chunk backstop on
the slow Windows runner (pure slowness, not a leak — per run-tests.cjs's own
comment). Weight install*/codex-* files (~10x a unit file) toward the per-chunk
budget so they spread across chunks instead of clustering; light-file chunking is
unchanged (weight 1). Adds harness regression tests (heavy split vs light control).

6d072435d0 test(#1975): consolidate 51 CLI + scripts-tooling regression tests into module suites
Fold 51 issue-named CLI black-box + scripts-tooling regression files into their
canonical module suites (runtime-launcher-parity, worktree-safety, install-*, managed-hooks,
read-guard, capability-registry, etc.), plus a NEW slash-command-namespace.test.cjs grouping
the 4 slash/colon-namespace-leak invariant suites that had no canonical owner. Verbatim
block-scoped describe wrappers; 427 subtests conserved 1:1.

Host-env pre-check (per B2): no CLI-receiving host sets a redirecting GSD_WORKSTREAM/GSD_PROJECT
value. One folded suite (bug-3668 runtime resolver) creates an extension-less PATH gsd-tools
stub + bash -c; co-locating it with the host's chmodSync tripped local/no-unguarded-nonportable-exec,
so it's now Windows-guarded (skip on win32) matching the host suite's own bash -c guard.

Regenerates regression-name allowlist (222->182), ratchets file-count allowlist (graphify 7->6,
docs entry removed), makes 26 relocated allow-test-rule exemptions issue-ref-compliant (ADR-456;
prunes stale ids). Repoints 13 tests/ references across CONTEXT.md, COMMANDS.md/FEATURES.md
(EN + ja/ko/pt/zh) and ADR-0002. lint:ci green.

Part of epic #1969. Closes #1975.

22f56f4431 ci(#1212): shard windows full-test lane to remove timeout cliff (#1222)
The `full test (windows-latest, *)` lane ran the entire unit suite (~740+
files) in one job whose wall-clock crept against the 20m cap and intermittently
CANCELLED (false-negative gate, observed on PR #1207). Prior tactical fixes
#869 (15→20m bump) and #1051 (handle-leak) deferred the cliff structurally.

Shard the unit suite across 3 parallel runners per OS/node leg so per-job
wall-clock is O(total/3) and stays under the cap as the suite grows.

- scripts/run-tests.cjs: add `--shard <i>/<n>` — a deterministic, balanced
  round-robin partition (fileIndex % n === i-1) over the SORTED selected file
  list. parseShardArg strictly validates i∈1..n, n≥1, integer-only; n=1 is a
  pure no-op. The 28K Windows argv chunking is preserved within each shard. A
  legitimately-empty shard (n > file count) exits 0; a selection empty BEFORE
  sharding still hits the discovery hard error. Composes with --suite and is
  order-independent (sorted before partition). Exports selectShard/parseShardArg.
- .github/workflows/test.yml: test-full becomes the 3 legs × 3 shards = 9-job
  cross-product (explicit include rows — a base shard dim does not cross-product
  with include legs, and a nested matrix.leg.os is unresolvable by the H1
  shell-policy linter). Unit suite runs sharded; integration/security run once
  per leg (shard 1). The Required tests fan-in is unchanged: it already needs
  test-full and checks the matrix-aggregate result, so a failed/cancelled shard
  fails the gate; the branch-protection check name is preserved.
- tests: partition/CLI + pure selectShard contract (completeness, disjointness,
  balance, determinism, boundaries, fast-check property) + parseShardArg
  validation, in run-tests-harness.test.cjs; a DEFECT.GENERATIVE-FIX parity
  guard (per-row shard values 1..N, every leg runs all shards, N == --shard /N
  denominator) + Required-tests name/needs pin, in ci-test-scope.test.cjs.

Closes #1212

5fa4dcd78c fix: recover silently-excluded test dirs + test-architecture audit hardening (#1195)
* fix: recurse test discovery so subdir test suites actually run

scripts/run-tests.cjs discovered tests with a flat readdirSync(testDir),
silently excluding tests/observability/ (4 files), tests/dispatch/ (1) and
tests/installer-migrations/ (1) — 94 passing tests — from `npm test` and all
CI lanes. Walk the tree recursively (relative subpaths preserved), classify
suites by basename, and add a fail-on-zero-executed guard for suite/default
runs (escape hatch GSD_ALLOW_EMPTY_SUITE=1) while preserving the empty
--files/--files-from path the CI inert lane relies on.

Unit suite 735 -> 741 files; surfaces ADR-227's observability/dispatch seam.

* test: retire 5 verified-worthless tests

Adversarial verification confirmed these 5 prove nothing — their coverage is

- command-routing-hub duplicate construct + duplicate ERROR_KINDS assertions
- no-cjs-sdk-handsync-tooling (guarded files that never existed on main; bug-190

* test: add ADR-218 release version-validation coverage

ADR-218 (reject leading-zero versions like 1.01.0; npm duplicate pre-check) had
zero tests — the logic lived only in release.yml bash. Add a test that extracts
the actual rejection regexes from the workflow and exercises them against a
boundary table (leading-zero/malformed rejected, valid accepted) plus structural
wiring assertions. Goes red if the regex is reverted to [0-9]+.

* test: redesign weak tests into behavioral, deterministic assertions

Per the ADR test audit, rewrite 27 weak test files (test-only, no source
changes) so each can go red for the defect it guards:
- kill pass-always assert.ok(true) placeholders (research-cli, worktree-baseref,
  bug-260 security guard, eslint-rules x24, clusters '|| true')
- replace source-text grep with behavioral calls (install Kilo, sh-hook-paths,
  plan-review-convergence) and add a repo-layout governance test
- de-flake real-clock/Math.random coupling (phase last_updated, bug-3707 mtime,
  context-utilization property, feat-3594)
- fix independence/shared-state violations (bug-492 singleton, issue-844 tmpRoot,
  core reapStaleTempFiles, active-workstream TTY, feat-488 GSD_HOME)
- strengthen property/shape-only tests (research-provider/store classification +
  collision) and unconditional plugin.json schema validation (issue-766)

Verified: all 28 files run together 1220 pass / 0 fail / 1 skip.

* chore: add no-tautological-assert lint rule, error in test suite

New custom ESLint rule (eslint-rules/no-tautological-assert.cjs) bans asserts
that can never fail: assert(true)/assert.ok(<always-truthy literal>),
'cond || true' inside an assert, and equality asserts comparing two identical
literals. Wired as error on tests/**; full sweep confirmed zero existing
violations so the suite stays green. Prevents the placeholder-assert regressions
the audit redesigns just removed. RuleTester coverage added (6 valid, 8 invalid).

Note: no-only-tests was already enforced via eslint-plugin-no-only-tests, so no
duplicate rule was added.

* chore: gate new allow-test-rule exemptions to require an issue ref

ADR-456 requires any allow-test-rule exemption added after the ADR to carry a
tracking issue number, but nothing enforced it. New ratchet gate
(scripts/lint-allow-test-rule-refs.cjs, wired into lint:ci) fails when a NEW
allow-test-rule comment lacks a #NNN/URL reference; the 323 existing untracked
exemptions are grandfathered in an allowlist that ratchets down as they gain
refs. Red-green verified (novel untracked offender fails; compliant passes).

* test: replace pre-existing raw NUL byte with escape in feat-3594 fixture

feat-3594's null-byte parser fixture contained a literal NUL byte (pre-existing
on next at b10e5681 — confirmed: base blob has 1 NUL, this fix has 0), which
made git treat the file as binary and would break grep/editors. Switch to the
\x00 escape; the runtime string value (a real NUL in the parser input) is
unchanged.

* test: address adversarial-review findings

Codex adversarial pass over the branch:
- capability-registry drift test no longer mutates the committed generated
  capability-registry.cjs in place (concurrency hazard) — uses in-memory
  checkPipeline comparison instead.
- allow-test-rule ratchet now detects exemptions in ALL comment forms (block
  /* */ too, matching no-source-grep) so a block comment can't bypass it;
  one newly-surfaced pre-existing offender grandfathered (323->324).
- install.test Kilo case asserts on what install(false,'kilo') actually writes
  rather than manually calling configureKiloPermissions (masked the call site).
- issue-766 drops the undeclared transitive ajv dep for explicit structural
  assertions from the schema fixture.
- adr-218 test notes the hotfix leading-zero gap is tracked in #1186.

* fix: address code-review findings (subdir discovery, rule + test gaps)

xhigh code review surfaced 15 confirmed issues, all fixed:
- run-tests.cjs --files now resolves subdir tests by bare basename + handles
  Windows backslash paths (ambiguous basenames error clearly).
- affected-tests-lib.cjs listTestFiles made recursive — the targeted CI lane was
  silently dropping changed subdir tests (same false-green class the audit fixed).
- no-tautological-assert now catches 'true || cond' and empty []/{}  equality.
- verify-test-quality: restore provenance-classification coverage, tighten the
  writeFile circular-detection check, guard the module-level file read.
- sh-hook-paths: cover the global-install .sh delegation branch (#2045 guard).
- active-workstream null-guard runs deterministically (no longer skipped on TTY).
- adr-218 structural guards tightened (major/minor leading-zero; needs: membership).
- repo-layout AGENTS.md guard no longer false-alarms on equivalent refactors.
- cross-ai ordering guard fails red when the step is missing.
- issue-766 parses required fields from the schema fixture (auto-enforced).

4698b3e349 fix(#1051): force-exit + per-chunk timeout for the windows full-test lane; close leaked test handles (#1054)
The `full test (windows-latest, 22)` job intermittently got CANCELLED at its
20m wall-clock cap with no failed test step — a false-negative gate (recurrence
of #869). Root cause: a unit test leaves an open event-loop handle, so the
chunk's `node --test` child hangs ~150s on Windows after its last test prints;
two such stalls push the already-~13m job past 20m.

Fix (defense in depth):
- run-tests.cjs: pass --test-force-exit (Node >=22; engines requires >=22.0.0)
  so the runner exits once all tests finish regardless of lingering handles —
  the durable backstop. Account for the flag in the argv-length ceiling.
- run-tests.cjs: add a per-chunk execFileSync timeout (default 600000ms, env
  RUN_TESTS_CHUNK_TIMEOUT_MS) that fails loudly with a diagnostic naming the
  chunk's files, so a hung chunk can never silently eat the job budget.
- perf-316 test: terminate both Worker threads on all paths (afterEach +
  finally) so they cannot outlive the test.
- locking-bugs test: kill spawned children in a finally that wraps the whole
  spawn -> waitFor -> barrier-release -> Promise.all sequence, so a barrier
  timeout no longer leaks live child processes.
- Refresh the stale synckit comment (synckit/SDK bridge was removed).

Regression tests in run-tests-harness: a hung chunk hits the per-chunk timeout
and fails with a clear message; force-exit lets a chunk with a leaked handle
exit cleanly.

a480510f54 fix(#872): make roadmap-phase-fallback tests hermetic against ambient GSD env (#873)
extractCurrentMilestone reads STATE.md via planningDir(cwd), which is
workstream-aware (honours GSD_PROJECT/GSD_WORKSTREAM). The fixtures write
STATE.md to the plain <tmp>/.planning/STATE.md, so a developer shell inside a
GSD workstream (GSD_WORKSTREAM exported) redirected the read to a non-existent
workstream subdir -> version=null -> closed milestone sections leaked into the
slice and assertions failed. Clean CI/Docker env never hit it. Not a Node-26
regex bug; reproduces identically on any Node with GSD_WORKSTREAM set.

- scripts/run-tests.cjs: strip GSD_PROJECT/GSD_WORKSTREAM before spawning test
  children so the local runner env matches clean CI/Docker.
- tests/roadmap-phase-fallback.test.cjs: file-level beforeEach/afterEach
  save/delete/restore of both vars; new regression test pinning workstream-aware
  STATE.md resolution.
- tests/run-tests-harness.test.cjs: guard asserting the runner strips both vars
  (so removing the deletion fails clean CI).

52f23ac0a0 fix(3597): chunk node --test spawn to survive Windows CreateProcess limit
Windows CreateProcess caps lpCommandLine at 32,767 chars. The original
`execFileSync(node, ['--test', ...546 paths])` exceeded that on every
Windows runner and exited within ~70ms with no test output. Linux/macOS
allow ~2 MB ARG_MAX so the same call worked there.

`scripts/run-tests.cjs` now splits selected files into chunks that keep
each spawn's argv under 28,000 chars (operator-overridable via
RUN_TESTS_MAX_CMDLINE_CHARS), runs them sequentially, and reports the
first non-zero exit. Cross-platform regression test forces chunking with
a low ceiling and asserts the `run-tests: chunk N/M …` stderr marker.

e82876fe45 feat(3597): split test suites and add Node 22/24/26 OS matrix
scripts/run-tests.cjs gains `--suite <name>` filtering using a filename
suffix convention (`*.security.test.cjs`, `*.integration.test.cjs`, …).
Files with no marker are `unit` (the default fast lane); files with a
marker land in the matching suite. No `--suite` flag preserves the prior
behavior of running every test (backcompat for `npm test` and
`npm run test:coverage`).

New package scripts wire the suites to stable entrypoints:
test:unit, test:integration, test:install, test:security, test:slow,
test:coverage:unit, test:coverage:all. Unknown suite → exit 2 with the
list of valid suites; empty suite → exit 0 with a stderr notice so empty
lanes (e.g. `security` before adversarial tests land) don't gate CI.

CI matrix grows from `ubuntu × {22,24}` + a single macOS lane to
`{ubuntu, macos, windows} × {22, 24, 26}`. `fail-fast: false` so one
lane failure doesn't cancel siblings. Node 26 is `continue-on-error`
until actions/setup-node stabilises that image. PR CI runs unit +
integration + security on every cell; `install` and `slow` only on
`main` push. A dedicated `coverage` job runs `test:coverage:unit` on
ubuntu/Node 24 and uploads the report.

Grouping policy lives in docs/TESTING-SUITES.md with a pointer from
CONTRIBUTING.md. New harness test covers arg parsing, filter selection,
empty-suite behavior, and failure propagation.

Closes #3597.
