a65cb291e8 fix(#4105): park the #3889 hang fixture on a settling timer (#4349)
* test(#4105): guard the #3889 hang fixture — must genuinely hang by itself and self-terminate

RED at this sha: against the current never-settling-promise body the guard
fails on the matrix line (Node 24: the unheld promise never self-terminates,
ceiling expires) and off it (v22-class runtimes: the child exits rc=1 after
~60ms, never reaching the still-hanging checkpoint). Same shape as the #4104
self-exit regression: spawn the exact served body, observe liveness past the
chunk bound and natural exit — no elapsed-value assertions.

* fix(#4105): park the #3889 hang fixture on a settling timer

The never-settling promise held no libuv handle, so the hang T1/T4 rely on
was a property of the runtime's test-runner shutdown behavior, not of the
fixture: v24/v26 happen to hold the loop open; v22-class runtimes exit rc=1
after ~60ms (# cancelled 1), so the chunk never reaches the timeout path and
the two timeout assertions assert nothing. Park on a settling 10s timer (the
#4104 idiom): an explicit handle makes the hang the fixture's on every Node
line, 10s >> the 2000ms chunk bound (margin asserted structurally in the
#4105 guard), ~0% CPU while parked, and guaranteed self-termination if a
kill orphans it. Behavior on the Node 24 matrix line is unchanged — the
chunk is still killed by the harness timeout (~2006ms) with the identical
diagnostic.

* test(#4105): drive the fixture guard off the child's exit event + runner timeout

Review-driven restructure (Memtrace flaky_test_fixed_sleep on the 200ms poll
interval): the guard now waits on the child's natural 'exit' event — no
polling interval, no hand-rolled watchdog setTimeout. The immortal-body bound
is the node:test per-test { timeout: 2 * HANG_PARK_MS } backstop, the
health-validation #663 house pattern and the no-elapsed-assertion-compliant
form. t.after still reaps the child on every path. Same failing-first arms:
still-hanging checkpoint, natural-exit (no signal), exit code 0.

86452da7cb fix(#4070): reserve shard 1's aux-suite cost out of the LPT unit-test packer (#4072)
* test(#4070): failing-first regression for shard1 aux-suite budget imbalance

- selectShard has no way to reserve virtual weight on a bin, so the LPT
  unit-test packer cannot account for shard 1's fixed aux-suite cost
  (integration/security/install/slow all pinned to shard 1/3).
- test.yml wires no such reserve into the workflow.
- ci-test-job-timeout-budget.test.cjs's LANE_COSTS entry for job `test`
  was stale (7m12s from run 30677442953, predating the aux-suite growth);
  corrected to the real evidence cited in #4070 (13m48s / cancelled at
  ~14m51s), which now honestly fails the file's own 1.5x headroom policy
  against the current 15-minute cap.

All three are expected RED on this commit; see
.gsd/bug/fix-4070-shard1-aux-suite-budget/50-test-matrix.md.

* fix(#4070): reserve shard 1's aux-suite cost out of the LPT unit-test packer

selectShard now accepts an optional initialWeights array giving one or more
bins a virtual head start before any file is placed, so LPT converges each
bin's FINAL total (assigned weight + head start) toward equal instead of
raw assigned weight alone. test.yml wires RUN_TESTS_SHARD_RESERVE=1:77 into
the full-scope unit-test step (gated on matrix.scope == 'full', so the
unrelated windows lane is unaffected) -- 77 weight units is the empirical
conversion of the aux suites' ~220s measured fixed cost, derived against
the real tests/test-timings.json (see the diagnosis artifact for the full
computation).

Also corrects two pieces of now-stale bookkeeping this issue exposed:
- ci-test-job-timeout-budget.test.cjs's LANE_COSTS entry for job `test`
  carried a 7m12s figure that predated the aux-suite growth; corrected to
  the real pre-fix evidence (13m48s / cancelled at ~14m51s, issue #4070),
  which requires raising timeout-minutes from 15 to 21 (1.5x headroom over
  the real worst-case measurement) to satisfy the file's own policy.
- test.yml's job-header and matrix comments, which still claimed the aux
  suites cost "~1m35s combined" (they now measure ~216-224s).

Closes the gap the previous commit's failing-first tests proved: selectShard
had no reserve-capacity mechanism and test.yml wired none in.

* fix(#4070): correct the reserved-weight property bound; cover main()'s reserve bounds check

Isolated code review found a genuine gap and gsd-test's real run confirmed a real
test bug it exposed:

- The fast-check property "no shard exceeds average(+reserve) + heaviest file" was
  falsified by gsd-test itself (weights=[1,1,1], total=2, reserve=6 on bin 0):
  selectShard is correct, the BOUND was wrong. A reserve large enough that its bin
  never receives a real item stays at exactly that reserve forever -- no amount of
  routing real items elsewhere can dilute a fixed head start below itself -- so the
  true bound is max(reserve, the classic Graham term), not the Graham term alone.
  Verified the corrected bound against the exact counterexample plus 20,000
  additional random trials (zero violations) before re-running gsd-test.

- Isolated review (MAJOR): the shard-total bounds check on RUN_TESTS_SHARD_RESERVE
  and its console.error fallback in main() were untested end-to-end --
  parseShardReserve itself has no concept of the shard total, so only main()
  enforces that guard, and nothing exercised it through the subprocess seam. Added
  an E2E harness test that sets RUN_TESTS_SHARD_RESERVE to an out-of-range index
  via the real CLI, asserts the fallback warning fires, AND asserts the resulting
  file selection is byte-identical to a no-reserve control run against the same
  injected timings table -- proving the reserve was actually ignored, not just
  that a warning printed.

* chore(#4070): backfill changeset PR number

pr:0 -> pr:4072

* fix(#4070): strip leaked RUN_TESTS_SHARD_RESERVE from the harness test's child env

Real GH Actions CI on this PR (run 33288554040, ubuntu shard 2/3) failed 7
tests in the shard-partitioning describe block, all with the same symptom:
`run-tests: no tests in suite "all"` where a real file count was expected.
gsd-test's own dockerized bench run never showed this, and ubuntu shards 1/3
and 3/3 (which run the same test.yml step) passed clean -- the discrepancy is
the tell: only shard 2/3 happened to schedule this specific test FILE for
that run, and the outer CI job's own environment is where the leak lives.

Root cause: test.yml's "Run unit tests" step now sets
RUN_TESTS_SHARD_RESERVE=1:77 (this issue's own reserve mechanism) on the
OUTER job that runs `npm run test:coverage:unit:raw -- --shard N`. The
harness test file's runHarness() helper spawns run-tests.cjs as a CHILD of
that same job via `{...process.env, ...extraEnv}`, so every pre-existing
--shard test in this describe block silently inherited the ambient reserve
-- even though none of them know it exists. A reserve of 77 weight units
utterly dwarfs the ~0.3 total weight of the 9-file synthetic fixtures these
tests use (none are in the real timings table, so all fall back to the same
tiny median weight), so shard index 1 is routed zero files every time --
exactly the observed "no tests" failures, and exactly the skewed 5/4 split
observed on the shard-2 test that expected a plain 3/3/3 round-robin.

Reproduced locally end to end (set RUN_TESTS_SHARD_RESERVE=1:77, spawn the
old runHarness against a synthetic 9-file fixture, --shard 1/3 -- reproduces
the exact "no tests in suite \"all\"" stderr) and confirmed the fix (env
stripped unless a test opts in via extraEnv, as the #4070 E2E bounds-check
test already does) resolves it, before re-running gsd-test.

This is a genuine bug this PR introduced -- a new ambient env var that a
pre-existing subprocess-spawning test helper didn't know to isolate against
-- not a pre-existing flake and not resource contention.

c1a2c33886 perf(#4012): two subprocess spawns, not five
My instrumentation suite tipped ubuntu shard 1/3 over its 15-minute job cap.
Measured, not guessed: baseline on next (c8f08b61f) passed that shard in
14m21s — 39 seconds of headroom — and the chunk-timeout instrumentation suite
I added costs 31,621ms, about 80% of what was left. The job ran 15m09s and
GitHub reported the cap as a cancel, which failed the required-tests rollup.

Cause is spawn count, not test content. The suite booted scripts/run-tests.cjs
five separate times — three success-path, two timeout-path — and each boot
globs the suite and spawns node --test children before any assertion runs. The
direct-require tests beside it cost milliseconds.

Now two spawns: one success run backing the elapsed-timing, temp-dir-non-leak
and no-EINVAL assertions, and one timeout run backing the in-flight-file
naming and the diagnostic wording. Every assertion is kept verbatim; only the
per-assertion subprocess boot is gone. Modelling per-boot overhead from the
measured total puts the saving around 18s, but that is an estimate derived
from one data point, not a measurement — the real number comes from CI.

The chunk timeout stays at 2000ms. It is already the lowest value used
anywhere in this file, and lowering it further would race a loaded CI box that
has to boot node --test, register the hang, and observe the kill inside the
window.

Worth recording separately: that lane has 39 seconds of margin on next, so it
is one cliff away from this happening to whoever adds the next test. The
per-chunk timing this PR adds is what made the attribution possible at all —
chunk 1/5 alone is 263s of a 900s budget, which was previously invisible.

bf8905fcc9 fix(#4012): a hang never emits the events I was listening for
The init marker settled it. The diagnostic reported "THE REPORTER LOADED BUT
RECORDED NO TEST EVENTS — the events file contains only the reporter's own
reporter:init marker", which refutes the reporter-never-loaded hypothesis and
leaves exactly one explanation.

The runner spawns a child process per test file and surfaces a subtest's
test:start / test:pass / test:fail to the parent's reporter only once the child
REPORTS that test — which happens when it completes. The fixture hangs forever,
so it never completes, so it never reports. I had recorded exactly those three
event types: the precise set that a hang guarantees you will never see. The
feature could not have worked for the case it was built for.

test:enqueue and test:dequeue are emitted by the runner as it queues and begins
each file, independent of anything inside finishing. test:dequeue is what
actually means "in flight", and it is now the primary signal, with test:start
kept as a secondary one. A file is in flight when it has been dequeued and has
no terminal event.

The four branches now describe states that are all real: the events file absent
(reporter never loaded); the init marker alone (the runner dequeued nothing at
all — genuinely surprising now rather than the expected outcome); everything
dequeued and terminated (the files finished and the process hung afterwards, a
handle leak); and one or more dequeued-but-unterminated files, named, which is
the case this whole feature exists to report.

Verified against the exact shape the real hang produces, by executing
analyzeChunkEvents on a synthetic events file: init + enqueue + dequeue with no
terminal event reports hangs.test.cjs as in flight, and appending a test:pass
clears it. Four more unit tests cover the ordering and multi-file cases with no
subprocess, so this logic is now checkable without a runner round-trip — which
matters, because every defect in this feature so far was visible only remotely.

T1 is untouched and should now pass for the right reason.

444137e63a fix(#4012): make the artifact say whether the reporter ever loaded
Down to 3 remote failures, all one chain. The explicit no-events reporting is
working — the diagnostic now states the events file does not exist, instead of
silently printing the generic message. But it then ASSERTED a cause: "the child
was killed before the reporter wrote even one event (process/spawn startup
stall, not a test hang)". That was a guess dressed as a finding, and the fixture
contradicts it: it starts a real test, so test:start should fire in milliseconds
against a 2000ms budget.

Two hypotheses remained and I could not separate them locally, because the local
test runner is hook-blocked here: either the custom reporter never LOADS in the
child, or it loads and no event reaches it before the SIGKILL.

Rather than guess a third time, the artifact now answers it. The reporter
appends a reporter:init line as its first action, before consuming anything, so
the file's contents discriminate: absent means the reporter never loaded;
init-only means it loaded and saw no test events; init plus events means it
works. The diagnostic has a branch for each and, where the cause is genuinely
unresolved, names both possibilities instead of picking one.

Also passes the reporter as a file:// URL via pathToFileURL. Node documents the
--test-reporter value as an import()-style specifier, and a bare absolute path
is not a portable one — notably on Windows. That is a correctness fix whichever
hypothesis holds, and it is a live candidate for the first. FIXED_OVERHEAD is
derived by reducing over the actual argv strings, so the longer URL is accounted
automatically.

Verified by execution, not assumption: composing the reporter against an EMPTY
event stream writes exactly one line, the init marker. That is the whole point
of the marker, so it is pinned by a test rather than left to inspection.

T1 stays red and untouched.

5504724d7a fix(#4012): the reporter body must return nully, not an iterable
Fourth failure on this feature, and this one was caused by the previous fix's
lint workaround.

  TypeError [ERR_INVALID_RETURN_VALUE]: Expected nully to be returned from the
  "body" function but got an instance of Array.

When stream.compose is given an async FUNCTION as the body, that function must
return nully. The reporter ended with 'return []' under a comment asserting
Node "still requires the exported function to return an iterable" — exactly
backwards, and the direct cause of 41 failures across every run-tests.cjs
invocation.

That return existed only to dodge ESLint's require-yield after the previous
commit converted async function* to async function. A lint workaround became a
runtime crash, and the comment written to justify it stated the opposite of the
contract. Both are now corrected to what the runtime actually does.

Verified by EXECUTION rather than by reading: composing the real reporter
against a fake event stream completes with no error and leaves both handled
events durably on disk, with the ignored event type skipped. The failing form
was reproduced the same way first, so the diagnosis is not inferred from the
stack trace alone.

The new unit test requires the reporter directly and asserts the returned value
is nully — the assertion that would have caught this before it reached the
runner — plus the exact NDJSON written. No subprocess, so this half of the
feature is verifiable without a full runner pass, which matters because every
defect in this feature so far has only been observable remotely.

T1 remains untouched and red.

7f2af28639 fix(#4012): the reporter sink must be a regular file, not devNull
Third failure on this feature, and this one broke everything rather than just
the diagnostic: 43 failures across every run-tests.cjs invocation.

  Error: EINVAL: invalid argument, fsync
  Emitted 'error' event on WriteStream instance

Node opens a WriteStream for a --test-reporter-destination and FSYNCS it on
close. fsync on /dev/null is EINVAL — it is a character device, not a regular
file. So os.devNull is not a usable reporter destination at all, and every
chunk crashed on exit.

The sink only ever needed to be a regular file that stays empty, since the
reporter writes its real output through appendFileSync to the path in
GSD_RUN_TESTS_EVENTS_FILE. It is now one fixed file inside the existing events
dir, pre-created rather than relying on the stream's create-on-open, and left
empty by design. One sink for the whole run, not per chunk, so its path length
stays constant — reporterOverhead feeds FIXED_OVERHEAD, which is computed once
before chunking, and a variable-length path would silently mis-account the
Windows argv ceiling.

The comment that named devNull now says why the destination must be a regular
file, so this does not get re-optimized back into the same crash.

Reaching for devNull was the mistake: it looks like the obviously correct way
to discard output, and it is, for a pipe or an fd — but not for something Node
is going to fsync. Each of the three failures on this feature was a different
edge of the same assumption, that a reporter destination behaves like ordinary
output.

The regression test asserts the closest externally observable consequence — a
normal run must not surface the EINVAL/fsync text. The argv construction lives
inside main() with no exported seam, and the sink is swept before a test could
stat it; adding a seam purely to assert that is left out rather than reshaping
production code for the test. Stated plainly rather than implied.

The failing T1 is untouched and still red.

0abd137ec7 fix(#4012): the events reporter has to survive SIGKILL
The remote run proved the instrumentation did not work. Timing landed —
"chunk 1/1 was killed after 2006ms" — but the in-flight-file naming produced
nothing and fell through to the pre-existing generic message. The feature I
wrote to diagnose a kill was itself destroyed by the kill.

Root cause, confirmed rather than assumed. The reporter yielded strings, which
node pipes into the --test-reporter-destination WriteStream. That stream
BUFFERS. execFileSync's timeout sends SIGKILL, which is uncatchable and gives
nothing a chance to flush, so the events sat in a buffer that died with the
child. The parent's own timer reported correctly because it lives in the
parent — which is exactly why half the feature looked fine.

The reporter now writes each event with fs.appendFileSync, unbuffered and
durable at the moment it happens, to a path passed through
GSD_RUN_TESTS_EVENTS_FILE. Env vars do not count toward the Windows
32,767-char argv ceiling, so moving the path out of argv also REDUCES
FIXED_OVERHEAD; the accounting moved with it rather than being left stale. The
destination is now a fixed devNull sink that stays empty by design.

Silence was the reason this was invisible for a whole run. Failing to read the
events file now says so explicitly, and distinguishes a file that could not be
read at all from one that exists but is empty — the generic fallback firing
quietly is what let a broken feature look like a working one. A write is
unbuffered but not atomic, so a kill can still interleave a partial line; the
reader tolerates exactly one unparsable trailing line and reports the complete
ones before it.

The failing T1 was left red and untouched rather than weakened to pass. Three
new unit tests cover the reader directly, with no subprocess, so the parsing
half is verifiable without a full runner pass: missing file, existing-but-empty
file, and a truncated final line.

Also adds ndjson-reporter.cjs to GSD_SCRIPTS_LIB_FILES in bin/install.js —
scripts/lib/ ships, and omitting it meant the file would install everywhere and
orphan on uninstall. That single omission caused 4 of the 7 remote failures.

8497833a15 fix(#4012): a killed chunk now names the file that was hanging
The per-chunk timeout fired correctly but reported almost nothing, so every
diagnosis cost a CI round-trip. run-tests.cjs logged chunk START only — no
timestamp, no duration, no end line — then on a kill printed all ~55 basenames
and asked the operator to work out whether output kept flowing (slow) or
stopped early (hang). It could not name the in-flight file because the child is
spawned with stdio inherit, deliberately, per #3597/#1051.

Three additions.

Per-chunk elapsed timing on every path, not just failures, so drift toward the
cap is visible before it becomes a kill. Every timing number in the
investigation behind this had to be reconstructed by hand from GitHub log
timestamps.

A second, machine-readable reporter running ALONGSIDE the human one, writing
NDJSON to its own file. On a kill that file is read back and the files with a
test:start and no matching completion are named, with the staleness of the last
event, so "stopped 480s ago at X" reads differently from "still emitting at
kill". stdio stays inherit and nothing is piped or tee'd — the maxBuffer and
live-output risks that shaped the original design are untouched.

Ranking of the killed chunk's files by known weight, flagging any absent from
tests/test-timings.json, since an unweighted file is an unknown quantity.

Two details that are correct rather than lucky. Passing --test-reporter at all
replaces node's implicit default, so the human reporter is now named explicitly
and reproduces node's own selection (spec on a TTY, tap otherwise) — visible
output is unchanged. And the destination path's chunk index is zero-padded to a
fixed width because FIXED_OVERHEAD is computed ONCE before chunking; a
variable-length path would have silently mis-accounted the Windows 32,767-char
argv ceiling and reintroduced #3597. The reporter flags are added to
FIXED_OVERHEAD exactly as --test-force-exit is.

The multi-reporter pairing and the stream.compose reporter contract were
confirmed against Node's v24 documentation, not recalled — the first draft
carried them as an unverified assumption and said so.

Also corrects a stale comment claiming the 600s cap sits "below the 20m job
cap". The lane is sharded 3x at timeout-minutes: 45; the windows shards were at
19m when chunk 1/5 was killed on b351c83e0 and c3e667df3. The per-chunk cap is
now the binding constraint, and the old silent-cancel model leads to the wrong
conclusion.

107eb8c1d9 feat(#3753): run docs guards on the PR that changes the docs they read (#3787)
A PR whose diff is entirely under docs/ runs zero tests, so a guard whose INPUT
is shipped prose cannot protect the PR lane of the diffs it exists to check. Its
only firing opportunity is after merge, on the shared branch -- which is how next
went red on dacae9273 while the PR that caused it (#3746) was green on every
check.

The docs-lint job in .github/workflows/docs-required.yml -- an ALREADY-REQUIRED
context -- now selects and runs the docs guards that read the specific docs files
the PR changed.

  scripts/docs-guard-registry.cjs    test file -> the docs paths it reads (63)
  scripts/select-docs-guards.cjs     pure (changedPaths, registry) -> test files
  scripts/lint-docs-guard-registration.cjs   drift guard, wired into lint:ci

scripts/ci-test-scope.cjs is NOT touched -- `git diff origin/next --` on it is
empty -- so #764's saving stands and its 21 pinning tests are untouched.

Selection: exact path; trailing-slash directory prefix (boundary-checked --
docs/adrenaline.md does NOT match docs/adr/, which a naive startsWith gets
wrong); and '*' for the 6 entries that walk docs/ generally or read a computed
path. Unknown maps to '*' -- guessing narrow is how a guard silently stops
running. Measured: a typo fix selects 6 of 63; docs/AGENTS.md selects 12;
docs/COMMANDS.md selects 18.

Four things this got wrong first, each found by an independent reviewer or by
probe, and each having been asserted safe in a comment:

1. The registry started as a RULE in ci-test-scope.cjs's RULES, on the theory
   that classify()'s !codeChanged normalization made it inert. True for
   docs-ONLY diffs; false for MIXED docs+code diffs, where codeChanged is true
   and the normalization never runs:

     node scripts/ci-test-scope.cjs --files "docs/a.md src/semver.cts"
       with the RULE:  25 targeted_tests
       origin/next:     3 targeted_tests

   Category error: RULES is the scoped lane's input; a docs-guard registry is a
   lane manifest for a consumer that never calls classify(). Extracted; pinned
   by value.

2. The second attempt was a dedicated workflow with paths: [docs/**]. Such a
   workflow never reports on a non-docs PR, so it can never be a required
   context without hanging every non-docs PR -- and a non-required check does not
   block a merge, so the guard would have been advisory and #3753 unfixed.
   docs-required.yml already has no paths: filter, already supplies the required
   docs-lint context, already computes docs_changed, and already ran one docs
   guard gated on it. Generalizing that step needs no ruleset edit at all.

3. The registry and the drift lint were built from ONE path-segment heuristic, so
   both were blind identically -- and blind at the guard that motivated the issue.
   The reader-call regex required a character BEFORE its keyword, so a callee
   named exactly read( / load( / parse( / doc( / file( / content( could never
   match; and only an INLINE path.join(ROOT,'docs','X.md') argument was caught,
   missing the two-step-via-variable form -- the MAJORITY spelling -- plus
   template literals and concatenation. Detector 1 fired on 14 of ~450 files, so
   35 genuine guards sat unregistered while the lint reported 0 violations,
   including cursor-reviewer (reads docs/COMMANDS.md, asserts
   .includes('--cursor')) and inventory-headings-countfree. The "accepted blind
   spot" this shipped with was the common case, not a fringe.

4. With detection fixed the true population is 115 files: 63 genuine guards, 52
   incidental. Running all 63 in a REQUIRED check on a one-line typo fix is the
   cost #764 exists to avoid -- install.test.cjs is 7840 lines and reads exactly
   one docs file, docs/AGENTS.md, for its frontmatter. Dropping it reproduces the
   bug; running it for a typo elsewhere is waste. Hence the map.

Then a second review round found six more, all fixed here:

- fragment-single-edit-propagation.install.test.cjs was EXEMPTED as
  "overlay fixture only". False: it reads the real docs/registries/eos.json and
  asserts on a registry entry name, and reads the real ADR-0001 and asserts its
  H1. A docs-only PR touching either would have gone green and red next -- #3753
  shipping again, from inside the fix for it. Now registered against both paths,
  and all 52 remaining exemptions were re-audited one by one.
- The SUITES-collision guard compared RAW registry keys, but run-tests.cjs strips
  a leading `tests/` BEFORE its suite check. So it caught 'all' and missed
  'tests/all' -- the only spelling that can actually occur, since every key
  carries the prefix. One typo would have run all 824 test files inside the
  required job. Now normalized the same way run-tests.cjs normalizes.
- The lint failed OPEN on an unreadable tests dir or candidate file: 0 violations,
  ok:true. A guard that cannot read its input must never report success.
- The exemption ratchet gated identity only, so a baselined file that later
  STARTED asserting on shipped docs stayed exempt silently -- 52 permanently blind
  files. The baseline now fingerprints the docs paths each exempted file
  references and fails when that set changes, naming what changed.
- The exemption marker was still honored inside a multi-line template literal in
  the header window. The scanner now tracks template-literal and block-comment
  state.
- `git diff --name-only | grep '^docs/'` silently dropped C-quoted non-ASCII docs
  paths, making docs_changed=false a green zero-guard check. Both call sites now
  pass -c core.quotepath=false.
- The run step was gated on hashFiles(), which a force-committed
  .docs-guard-tests.txt would satisfy. The step now rm -f's both scratch files
  first and gates on an output it sets itself.

Three empty states, deliberately distinct, because conflating them rebuilds
#3753: an empty or malformed registry HARD-FAILS; docs changed with no guard
covering them logs and skips; no docs change is already gated. The middle state
must never be expressed as an empty --files-from, which prints `no tests in suite
"all"` and exits 0 -- a green check that guarded nothing. With the current
registry that state is unreachable, because the six '*' entries always match;
the branch is kept as defensive handling for a future registry and says so.

timeout-minutes: 15 bounds the required job against a hanging fork-supplied test;
it had none. npm ci was added because the job never installed dependencies -- the
previous single-file step got away without it, the registry does not.

docs/contributing/docs-guard-registration.md documents the rule, following its
sibling cross-platform-portability-rules.md, and CONTRIBUTING.md's CI Test
Quality Checks table links to it. It is also load-bearing: without a docs/ file
in the diff this PR would not have triggered its own lane, shipping an
unexercised change to a required check.

One unrelated fix, included because this PR surfaced it and CLAUDE.md forbids
deferring a defect found while working. On this branch's first CI run,
`full test (windows-latest, 24, shard 3/3)` was CANCELLED at exactly 30 minutes;
tests were still passing 0.8s before the cancel, so it is a wall-clock timeout,
not a hang, and a cancelled job reddens `Required tests`.

The cause is not this PR's test file, which costs ~60ms. Shard composition is
unstable: adding ONE file to the unit suite reshuffled 115 of 268 files between
shards, and shard 3 drew a heavier mix. Underneath that is a real pre-existing
defect. tests/ci-test-job-timeout-budget.test.cjs requires every lane's budget to
be >= 1.5x its MEASURED cost -- "a lane that got slower must be re-budgeted, not
excused" -- and its test-full entry recorded 19m from a windows-22 shard. That is
stale. Measured on `next` with none of this PR's changes present: 26m18s (run
32614439702, windows-latest/24 shard 3/3), 23m36s and 23m17s on shard 2/3. So the
lane costs ~26m and the 30-minute cap carried 1.14x headroom, not 1.5x. The gate
had been out of compliance with its own rule; this PR was merely the file
addition that reshuffled shard 3 past the cliff.

Fixed as that file prescribes: measuredMinutes 19 -> 27 with fresh evidence, and
test-full timeout-minutes 30 -> 45. The rule's minimum for 27m is 41; 45 is
deliberately above it because the reshuffle means per-shard worst case moves run
to run, and a budget pinned to the exact minimum would be re-breached by the next
test file anyone adds. Only that one job's timeout changed; test.yml's scope,
matrix and steps are untouched, so #764's saving is unaffected.

Raising that cap let the Windows shard finish (28m45s, inside 45) and uncovered
a real failure the 30-minute cancel had been masking:
`new quick-task branch branches off origin/main (#2916)` died with
`outcome=timed_out exitCode=null`, SIGTERM, at the 15000ms bound.

tests/quick-branching.test.cjs:149 `runStep` runs a `#!/usr/bin/env bash` script
executing MULTIPLE git commands, but was bound to GIT_TIMEOUT_MS (15000) -- the
norm for a SINGLE git plumbing call. tests/helpers/timeouts.cjs already documents
this exact failure and exists to fix it: HOOK_FANOUT_TIMEOUT_MS was created after
PR #3285 recorded "outcome=timed_out exitCode=null at exactly the 15000ms probe
bound while every other lane passed the same commit", and calls that "a bound
sized for the wrong class, not a slow machine". Our failure is that case
verbatim, so both sites move to the class norm rather than to a bigger number.

The same class also failed on `next` itself 21 hours earlier -- run 32608945654,
windows-latest/24 shard 1/3, `plan touching only src/ in a submodule project
keeps worktree isolation ENABLED` -- where tests/worktree-safety.test.cjs:5845
`runGate` fans out to `git config --file .gitmodules` under a hardcoded 30000.
Fixed too, since it is a defect in the tree regardless of which branch surfaced
it.

A survey of the whole tests/ tree found the same class-mismatch at further
bash fan-out sites bound under 60000ms, and the maintainer approved sweeping
them rather than leaving them latent to surface the same way one at a time. 16
fan-out sites across 16 files now use the class norm.

The sweep is class-correctness, not raising numbers until things pass. Sites
were moved ONLY where the bash body demonstrably spawns something (git, node,
npm, a CLI); self-contained shell snippets were left where they are, and are
listed as deliberately unchanged: pure if/printf bodies (copilot-install), pure
array/case builtins (code-review-pipeline-regression:638), a documented
pure-shell gsd_run stub (host-integration), single-process hook calls
(workflow-guard:222/271/302), and a deliberately tight 5000ms fast-check hook
(gsd-write-guard.property). Nothing was lowered. process-seam.test.cjs:513
(literal 300) is untouched on purpose -- it tests timeout BEHAVIOR, so raising
it would destroy what it asserts.

Shared file-level constants were the trap here, and were handled per file rather
than by redefinition: GIT_TIMEOUT_MS has ~15 users in git-base-branch and only 1
is a fan-out; WORKTREE_TIMEOUT_MS has 16 users in worktree.test.cjs and 3 are;
PROBE_TIMEOUT_MS has several in three more files. In each the CALL SITE was
changed and the constant left alone, so no single-plumbing-call site silently
inherited a 60s bound. The one exception is hooks-opt-in.test.cjs, where
HOOK_TIMEOUT_MS has exactly one consumer -- spawnHook, the fan-out itself -- so
redefining it is identical in effect and reads better.

Only two of these sites have actually been observed failing. The rest cite that
shared class and those two run ids rather than inventing evidence of their own.

bc5c362610 fix(#2665): replace the hand-synced TEST_ENV_BASE copies with the canonical import
Eight declarations were kept in sync by hand with no parity assertion. The drift
was already in the tree: api-coverage-gate-e2e and representative-corpus declared
TERM_SESSION, but the real variable is TERM_SESSION_ID, so both scrubbed nothing
for that slot and leaked TERM_SESSION_ID into every child. Deleting the copies
removes the dead key with them -- there is no longer a second place to get wrong.

run-tests-harness keeps its local session-identity literal: that helper mirrors
the production runGsdTools to prove its CONTRACT, so it must not re-import what
it is testing. The config-LOCATION keys are a safety scrub rather than part of
that contract, so it spreads the canonical derived set and keeps the rest local.

Addresses review findings: Blocker 2, Blocker 3.

08021b02c0 fix(#2665): scrub config-location env vars in every TEST_ENV_BASE declaration
TEST_ENV_BASE blanks session-identity variables but none of the three that
decide WHERE a child process writes: CLAUDE_CONFIG_DIR, GSD_RUNTIME and
CODEX_HOME. The config-home resolver is env-first (runtime-homes.cts, the
dot-home case consults the env var before the home-derived fallback), so an
ambient CLAUDE_CONFIG_DIR in the developer's shell beats a call site that
sandboxes only HOME. The suite then writes into the developer's real config
directory -- including a registered skill under <configDir>/skills/ whose
body carries behavioural directives that load into later sessions.

Blank all three alongside the session-identity vars. `...env` still spreads
last, so the five call sites that already constrain these locally keep
winning with their explicit values.

TEST_ENV_BASE is re-declared in nine files, so the three lines are added
nine times rather than once. Consolidating the nine into a single exported
constant -- and fixing the TERM_SESSION / TERM_SESSION_ID drift between the
copies -- is deliberately left out of this change; see the PR body.

One call site needed adjusting. capability-state.test.cjs's
`capability state --runtime claude` CLI test passed no env at all and
compared the CHILD's resolved config dir against the PARENT process's
getGlobalConfigDir('claude'). That agreed only because the child inherited
the developer's ambient CLAUDE_CONFIG_DIR -- i.e. it passed *because of*
the leak. It now redirects both runtime homes into the sandbox and asserts
against values the test controls, so it is hermetic with the variable set
or unset.

Regression case folded into the owning module's test file rather than a new
bug-NNNN file, per scripts/lint-regression-test-names.cjs. It sets the
variable on the PARENT process, which is the actual vector; setting it in
the per-call env argument would exercise a path that was never broken.

9faacc0c15 test(#3148): bound the long tail and delete the unbounded-spawn allowlist (#3192)
* test(#3148): bound the long tail and delete the allowlist

Migrates the final 170 unbounded sync spawn sites across 49 files, then
removes the allowlist entirely. local/no-unbounded-spawn now runs with no
exemption surface across tests/**: there is no file to add a name to.

drift-detection's throw-native git() helper routes to gitOrThrow -- bare
runGit would have taken 16 call sites quiet on failure. commands.test.cjs
has two independently-scoped runGsdTools/runCli helpers, one already bounded
and one not; they are kept distinct rather than unified, the same trap as the
two same-named git() helpers in Wave 1.

runNpm's bound was erasable. Its options spread callerOptions after the
defaults, so an explicit timeout:undefined silently dropped the 180000ms
bound -- the rule flagged it and was right; it was not a false positive. Fixed
by destructuring with a default, with a test that fails when the default is
removed.

Two sites stay on a raw spawn with an explicit timeout because the seam
cannot express them: one needs shell:true for npm.cmd on Windows, one
redirects stdout to a real fd. Both are the rule's own documented second
option, not an escape from it.

Closure verified rather than asserted: the derivation scan reports 0 unbounded
spawn helpers and 0 unbounded direct git call sites, and a temporary file
carrying an unbounded spawn still errors with the allowlist gone.

Closes #3064.

* test(#3148): close a hole in the guard's own eslint-disable ban

The ban listed only the top level of tests/, so it was blind to 37 .cjs
files under tests/helpers, qa, observability, fixtures and dispatch. With the
allowlist deleted this test is the sole remaining way to detect someone
silencing the rule inline, so the gap was load-bearing: a nested file could
carry an unbounded spawn plus an eslint-disable and pass everything.

Proven before and after. A probe planted under tests/helpers with both was
invisible to the guard and clean under eslint; after making the listing
recursive the guard fails on it. The scanned set goes from 771 files to 808.

Pre-existing since the guard shipped, but this wave is what promoted it to
sole defense, so it is fixed here rather than filed.

Also converts the last hand-rolled throw check to throwIfFailed and the last
re-derived legacy shape to compose toLegacyResult, which makes the epic's
none-remain claim true rather than nearly true. toLegacyResult itself is not
widened -- eight callers depend on its shape and one consumer does not
justify changing a shared contract.

* fix(#3148): correct seam incoherence at the bound and a slow review-lane error path

Two real failures from the remote runner, both fixed at the cause.

The seam could return outcome TIMED_OUT together with exitCode 0. At the
exact bound spawnSync reports ETIMEDOUT while the child has already exited
with a real status, and toSeamResult classified on the error code while
passing status straight through -- an incoherent pair its own boundary test
was written to catch, and did. A status that is not null is direct evidence
the child exited on its own, so it now decides the outcome before the
error-code branches run. process-seam.cjs was deliberately untouched by every
earlier wave; this is a defect in the module itself, kept surgical, with a
unit test that fails against the old logic.

review-lane with an unknown subcommand fell through to its usage error only
after loading the capability registry and building a per-lane plan, which
spawns one child process per lane -- up to twelve. The error path took
~1288ms instead of ~119ms, and under bench load it outran a caller's spawn
timeout and was killed before writing anything, which is the empty stdout and
stderr CI saw. It now fails fast before any of that work begins.

This is the epic's first production change. It is user-facing, so it carries
a changeset rather than a no-changelog label.

* test(#3148): replace a real-race timeout test with a deterministic one

E9 raced git rev-parse against a 1ms bound and assumed git always lost. On a
warm container git finishes first, spawnSync returns status 0 with no error
at all, the seam correctly classifies EXITED, and gitOrThrow correctly does
not throw -- so the test failed on both lanes. A probe confirms a genuine
timeout always carries status null, so this was never the seam misbehaving.

Raising the bound would only lengthen the odds, which is the same defect with
better luck. The test now drives gitOrThrow against a stubbed runGit that
returns a synthetic TIMED_OUT result, so it asserts exactly what it always
meant to -- that a timeout propagates as a throw -- with no timing
dependence. Five consecutive runs are identical where the old one varied.

I wrote this test in Wave 0; it is a real-race test by construction and
CLAUDE.md says to replace those rather than re-run them.

7dd9e59f6b test(#3090): stop exempting violations under categories that do not fit
An allow-test-rule annotation citing a category that does not apply is worse
than no annotation, because it reads as reviewed. Eight were confirmed by
reading the assertions each one covered, and auditing the rest found five more
plus one refutation — a converter test whose wording described the wrong
mechanism while the covered assertion genuinely was deployed-text.

The instructive one used the CANONICAL string for the same mistake: STATE.md
command output labelled as a deployed artifact. A canonical string is not
evidence the category fits, which is why normalising strings alone would have
laundered the problem rather than fixed it. Every mapping the audit had inferred
rather than code-verified was spot-checked before rewriting, and the ones that
turned out not to fit were re-annotated rather than relabelled.

Fourteen STATE.md assertions had a typed extractor available all along and now
use it; their annotations came out because nothing needs exempting. Eight
assertions genuinely need a production change first — CLI stdout and stderr with
no structured mode — and are tagged pending-migration-to-typed-ir citing #3090,
which is what that category is for. It had zero real uses before this, while one
file carried a real citation to migration issue #2974 under a non-canonical tag.

Six annotations covered assertions that do no text matching at all. An exemption
for a violation that does not exist is noise that makes the real ones harder to
audit; those are removed.

atomic-write-coverage gains the annotation it always warranted — its own
docstring describes a structural-regression-guard while the file carried none.

Fifty-nine non-canonical strings across roughly thirty files are normalised, and
the allow-test-rule allowlist is regenerated to match. 472 annotations became
463: every one now uses a canonical category, and the two remaining
non-canonical strings are ESLint RuleTester fixtures, not annotations.

bf0d715733 fix(#2472): cost-balanced test sharding and pinned CI base commit (#2480)
* fix(#2472): weight-aware shard partition

Windows shard 1/3 hit the 20-minute job cap with no failing assertion. Root
cause is the shard layer, not the chunk layer: selectShard partitioned by
sorted ARRAY INDEX (k % n, #1212), which balances file COUNTS and ignores
file COST. On the real unit suite that produced 12.4m / 19.2m / 15.2m — a
1.23x max/ideal ratio leaving the heaviest shard 5% under the cap. Because
assignment keyed off position, inserting one test file re-indexed every file
after it and could tip that shard over; deterministic, so a re-run reproduced
it exactly.

This is NOT the chunk packer (#2456/#2463). That fix works and applies one
level down, WITHIN a shard. The across-shard partition predated it and never
consumed the cost table. Both layers now share one cost model.

selectShard takes an optional weightOf and, when given one, partitions by LPT
(longest-processing-time-first) — the same algorithm packChunks uses. Omitting
it keeps the legacy round-robin byte-identical, so every existing test above
still exercises that path unchanged and callers without timing data lose
nothing. A missing timings table yields uniform weight 1, under which LPT
degenerates to the equal-count split.

Projected on the real suite: 16.4/17.3/13.0 -> 15.6/15.6/15.6 (worst shard
17.3m -> 15.6m).

Tests: a skewed-cost regression (round-robin clusters all four heavy files
onto one shard at 2.98x ideal; LPT does not), back-compat equivalence,
determinism, tie-breaking, order preservation, and two fast-check properties
— the partition is exhaustive and disjoint (getting this wrong silently DROPS
tests from CI, the worst failure mode for a harness), and no shard exceeds
average + heaviest file.

Two assertions were corrected during authoring rather than shipped wrong:
- an initial "LPT within 4/3 of ideal" bound was false. The 4/3 figure is
  relative to the OPTIMAL makespan, not the average, and the two differ when
  item sizes force a pairing. Replaced with Graham's average+max bound, which
  is what is actually provable.
- "weighted is never worse than round-robin" is also false; fast-check
  falsified it with [19316,10190,1,9128,29353,20227] over 2 shards (rr 48670,
  lpt 48671). Round-robin can win by luck on a specific input. Dropped, with
  the counterexample recorded in place so it is not re-asserted later.

Closes #2472

* fix(#2472): rotate tied bins; restore #1212 test block; lazy cost table

Isolated-review findings, all fixed.

HIGH — zero weights collapsed the whole partition onto shard 1. The
lightest-bin scan compared weight only, and adding a zero-weight file leaves
its bin's weight unchanged, so bin 0 stayed tied-minimum forever and every
such file landed on it. Verified: all-zero weights gave shard1=[a..f],
shard2=[], shard3=[] — two of three CI runners idle while one ran everything.
Reachable through safeWeight's own clamp (a NaN/negative/Infinity entry in a
corrupted or hand-edited timings table) and through any genuine 0ms
measurement, so the clamp reproduced the exact failure its comment claimed to
prevent. Ties now break on file COUNT after weight, which rotates. Pinned by
two regression tests (all-zero, and clamped NaN/negative/Infinity) plus a
property over list size x shard count. The live table has no 0ms entries
(min 19ms), so production was not affected — but nothing prevented it.

MEDIUM — the new describe block had swallowed #1212's pre-existing property
test, which is why a test under a "weight-aware" heading never passed a
weigher. That was a bad block boundary in the previous commit, not a bad
test: the #2472 describe was opened before #1212's last test instead of
after. Moved back where it belongs; #1212 is 762-879 and #2472 is 894-1082.

LOW — that relocated property test ran unseeded. Seeded (12120) per the
repo's property-test convention so a failure reproduces. Verified passing
under the new seed.

LOW — hoisting the timings load above the shard block charged a readFileSync
+ JSON.parse to invocations that exit before needing it (empty selection,
--files matching nothing). Now lazily memoized, so neither consumer reads the
table unless it is used and it is still read at most once.

Real-suite projection unchanged at 15.6m / 15.6m / 15.6m.

* docs(#2472): correct stale round-robin sharding descriptions

The partition is now cost-balanced, so the header block in run-tests.cjs
and the two comments in test.yml describing '--shard' as a round-robin over
sorted file index were actively wrong. Updated to describe LPT over measured
duration, and to state the degenerate case explicitly: with no timing data
every file weighs the same and the partition collapses back to k % n, which
is why the pre-existing #1212 CLI tests still pass unchanged (their nine
synthetic files are absent from the timings table, so all take the identical
median weight).

Remaining 'round-robin' mentions are correct — they describe the unweighted
fallback path.

Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

* fix(#2472): shard diagnostics, cost-routing E2E test, table validation

Second orthogonal review (operational lens) findings, all fixed.

HIGH — cross-runner partition divergence. Each of the up-to-12 CI jobs runs
its own 'merge base into head' and computes its own partition, so if the
inputs differ between jobs (the file list, or the timings table) two jobs can
place the same file in different shards or in none. Every job stays
internally exhaustive and disjoint, so nothing errors: a test simply never
runs and CI stays green.

The risk class is pre-existing — round-robin diverges identically when the
file set differs between jobs, which is literally this issue's insertion
instability — but weighting adds tests/test-timings.json as a second input
that must match, so it widens the hole. Properly closing it means pinning the
partition inputs per run, a workflow change beyond this fix.

What IS closed here is the silence. Each shard now prints an input
fingerprint over the FULL pre-partition list and the weight assigned to each
file — deliberately not this shard's slice, which would differ by design and
be useless for comparison. All shard jobs of one run must print an identical
sig; a mismatch is direct proof the runners disagreed about the input.
Verified: three independent computations agree, and the sig changes when the
input drifts by one file.

MEDIUM — nothing proved main() actually threads fileWeightOf() into
selectShard. Every pre-existing --shard E2E test uses synthetic filenames
absent from the real table, so all collapse to a uniform median weight, under
which LPT is mathematically identical to k % n — a typo on that one wiring
line would have passed the whole suite. Added an E2E test that injects a
table via RUN_TESTS_TIMINGS_FILE with differing costs, placing the heavy
files at exactly the indices round-robin hands to shard 1, and asserts shard 1
does NOT receive all three. Plus a test that all three shards emit the same
sig.

MEDIUM/LOW — no observability. The diagnostic line now reports files,
weighed count, aggregate weight, and whether the table loaded, so a table
that silently failed to parse shows table=absent/weighed=0 instead of being
indistinguishable from a healthy load. (The reviewer confirmed the advisory
fallback is already live on next: feat-2296-provider-escalation.test.cjs is
missing from the table.)

LOW — typeof [] === 'object', so a hand-edit turning the map into a list was
accepted as a valid table. Now rejected via Array.isArray, falling back to
uniform weight like any other malformed table.

LOW — stale round-robin wording in ci-test-scope.test.cjs.

* fix(#2472): pin every CI job to one base commit

Closes the cross-runner divergence at its source instead of only making it
visible.

Each job of a run executes the rebase-check step independently, minutes apart
across a 12-job matrix, and merged the MOVING origin/<branch> ref. If the base
advanced mid-run, different jobs merged different trees. That was survivable
when jobs only had to agree on pass/fail; it is not once they must agree on a
PARTITION. Each shard job computes the whole split and keeps its own slice, so
jobs working from different trees can place a file in two shards or in none —
and every job still looks internally consistent, so nothing errors. A test
silently never runs and CI stays green.

ci-rebase-check.cjs now accepts CI_REBASE_BASE_SHA and pins BOTH the fetch and
the merge to that one commit, so the two can never disagree. test.yml passes
github.event.pull_request.base.sha on all three rebase-check steps; that value
is fixed for the life of a run, so all jobs merge the identical base.

This also closes the PRE-EXISTING half of the divergence. Round-robin had the
same exposure whenever the test-file set differed between jobs — that is this
issue's insertion instability — so the pin fixes the older hole too, not just
the timings-table input weighting added.

Only a full 40-hex sha is accepted; empty (push/workflow_dispatch), malformed,
or injected values fall back to the branch ref rather than handing an arbitrary
string to git fetch as a refspec. resolveBaseRefs is extracted pure and
exported, and runMain is guarded behind require.main === module, so the pin
contract is testable without spawning git.

Tests (tests/ci-test-scope.test.cjs): every rebase-check step must carry the
pin; a valid sha pins both refs; absence falls back correctly; and five hostile
values — short sha, uppercase, --upload-pack= injection, ref expression, empty
— are each rejected.

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.

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.

* 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.

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).

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.

Closes #1051

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.
