The windows-test-parity ratchet greps test source for fs.rmSync-without-
maxRetries (and six other Windows-portability anti-patterns), failing when an
integer offender COUNT exceeds a frozen baseline (rmSync: 95). A count ratchet
is a Goodhart metric: fixing one offender and adding another keeps the count
constant, so a new defect slips through green. Replace it — and every other
count ratchet in the repo — with a layered, masking-proof design.
Behavioral seam test
- tests/helpers-cleanup.test.cjs proves helpers.cleanup() carries the Windows
EBUSY retry budget. cleanup() delegates retries to Node's fs.rmSync via
maxRetries (it owns no loop), so the test asserts the option contract
(recursive/force/maxRetries>0/retryDelay>0) + real-FS removal + the cwd-guard,
rather than a loop that does not exist. The EBUSY risk is now tested ONCE at
the helper, not approximated textually at every call site.
Write-time ESLint rule (AST-accurate, replaces the grep)
- eslint-rules/no-raw-rmsync-in-tests.cjs (error in tests/**/*.test.cjs) bans
raw fs.rmSync, steering to cleanup(). Catches member, computed (fs['rmSync']),
destructured and aliased forms; escape hatch is inline
`// eslint-disable-next-line local/no-raw-rmsync-in-tests -- <reason>` only.
- Migrated 336 raw fs.rmSync teardown calls across ~116 test files to cleanup().
~18 genuinely load-bearing sites (mid-test SUT/fault-injection removals,
error-swallowing or name-colliding local teardown helpers) keep the raw call
with an inline eslint-disable + reason.
Shared anti-ratchet primitive
- scripts/lib/allowlist-ratchet.cjs:
- assertWithinAllowlist: fails on NOVEL ids (new offender introduced) AND on
STALE ids (a known offender was fixed but not pruned) — identity, not count,
and a ratchet DOWN toward zero.
- assertTightCeiling: a size/length budget whose ceiling must stay within a
grace band of the high-water mark, so budgets may only tighten, never creep.
Ratchets converted onto the primitive
- windows-test-parity-guard.test.cjs: rmSync rule deleted (now ESLint-enforced);
the remaining six patterns moved from integer baselines to named-set
allowlists with ratchet-down.
- scripts/lint-test-file-count.{cjs,allowlist.json}: per-module integer counts →
named filename sets (closes the swap-a-file-keep-the-count blind spot); a
module dropping under cap now FAILS to force pruning its allowlist entry.
- enh-2790 skill-count `<= 63` → named skill allowlist (ratchets toward ~58).
Size budgets hardened (tighten-only)
- agent-size / workflow-size / feat-3039 help-tiered: ceilings lowered to the
current high-water mark and an assertTightCeiling anti-creep check added per
tier. Fixed external-contract limits (description ≤100 chars, agent ≤100 KB)
are intentionally left as-is — they are not grandfathered creeping budgets.
No user-facing behavior change (tests + tooling only); no USER_FACING_PREFIXES
touched, so no changeset fragment is required.

Two follow-ups on commit 80f14cac (which hardened quick-branching with a
trunk fixture):
1. quick-branching.test.cjs: add a `defaultBranch` parameter to
setupFixture and run the "branches off origin/HEAD" assertion against
both `main` and `trunk`. The wholesale switch to trunk in 80f14cac
removed coverage of the conventional `main` path; parameterizing
restores it without giving up the symbolic-ref guarantee.
2. bug-2916-handle-branching-default-base.test.cjs: apply the same
parameterization here. handle_branching has the same default-branch
detection logic as Step 2.5, so it deserves the same trunk regression
guard. Previously this file only exercised `main`.
A regression that silently defaults to `main` instead of consulting
`git symbolic-ref refs/remotes/origin/HEAD` now fails the `trunk`
variant in both files.
Tests: 10/10 in the touched suites.
- Restrict the "init parse list includes branch_name" assertion to
the bash blocks inside Step 2 (Initialize) so an unrelated step
that mentions branch_name cannot mask the contract.
- Switch the fixture's default branch from main to trunk so the
symbolic-ref code path is locked in: a regression that silently
defaults to "main" instead of consulting origin/HEAD now fails.
Addresses CodeRabbit review on PR #2921.

CodeRabbit nitpick (per project policy `feedback_no_source_grep_tests`):
the prior `tests/quick-branching.test.cjs` asserted branching correctness
by `.includes()`-grepping the raw markdown content for literal command
substrings. Those assertions stayed green even when the underlying
behavior regressed (e.g. when `git checkout -b` was unconditionally run
from the wrong HEAD).
Replace with the same pattern as `bug-2916-handle-branching-default-base
.test.cjs`:
- Structurally extract the Step 2.5 bash block from quick.md by
walking the markdown for fenced ```bash blocks under the heading
(no regex on prose).
- Spin up a fixture git repo with a bare origin, a clone whose
`origin/HEAD` points at `main`, and a checked-out previous-task
branch carrying its own unmerged commit.
- Execute the extracted bash block via `bash -c` and assert that
the new branch's tip equals `origin/main` (0 commits inherited
from the previous-task HEAD).
- Add a reuse test that pre-creates the target branch with its own
commit and verifies the script switches back to it without a
rebase or reset.
The two informational tests (workflow file exists, branching runs
before task-directory creation) are retained, plus the `branch_name`
parsing assertion is rewritten to walk fenced bash blocks rather than
substring-grep arbitrary content.
handle_branching in execute-phase.md (and the equivalent step in quick.md)
created the per-phase branch from whatever branch happened to be checked
out — typically the previous phase's still-unmerged feature branch — so
consecutive phases compounded on top of each other and stayed unpushed.
Detect the default branch via git symbolic-ref refs/remotes/origin/HEAD,
fast-forward it from origin, and fork the new phase branch off that tip.
Existing branches are still reused as-is. Dirty working trees fall back
to current HEAD with a loud warning, and a post-creation guard reports
any inherited commits.
Regression test extracts the bash from the <step name="handle_branching">
block structurally and runs it against a fixture repo where HEAD sits on
a previous-phase branch with extra commits.

* refactor(tests): standardize to node:assert/strict and t.after() per CONTRIBUTING.md
- Replace require('node:assert') with require('node:assert/strict') across
all 73 test files to enforce strict equality (no type coercion)
- Replace try/finally cleanup blocks with t.after() hooks in core.test.cjs
and hooks-opt-in.test.cjs per the test lifecycle standards
- Utility functions in codex-config and security-scan retain try/finally
as that is appropriate for per-function resource guards, not lifecycle hooks
Closes#1674

* perf(tests): add --test-concurrency=4 to test runner for parallel file execution
Node.js --test-concurrency controls how many test files run as parallel child
processes. Set to 4 by default, configurable via TEST_CONCURRENCY env var.
Fixes tests at a known level rather than inheriting os.availableParallelism()
which varies across CI environments.

* fix(security): allowlist verify.test.cjs in prompt-injection scanner
tests/verify.test.cjs uses <human>...</human> as GSD phase task-type
XML (meaning "a human should verify this step"), which matches the
scanner's fake-message-boundary pattern for LLM APIs. This is a
false positive — add it to the allowlist alongside the other test files
that legitimately contain injection-adjacent patterns.
