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.

Replace the per-render readdirSync().filter().map(statSync).sort() chain
with a single-pass max-by-mtime loop. Drops the O(n log n) sort and the
throwaway intermediate array; I/O and resolved-file behavior are identical.
Adds the first behavior-lock test for the todo-resolution path.
The larger disk-backed cache win from the issue is deferred: statusline is
a fresh child process per render, so any cache must be disk-backed with
invalidation/atomic-write design that needs maintainer input.

Bug #2453: After tsc builds sdk/dist/cli.js, npm install -g from a local
directory does not chmod the bin-script target (unlike tarball extraction).
The file lands at mode 644, the gsd-sdk symlink points at a non-executable
file, and command -v gsd-sdk fails on every first install. Fix: explicitly
chmodSync(cliPath, 0o755) immediately after npm install -g completes,
mirroring the pattern used for hook files throughout the installer.
Bug #2451: gsd-context-monitor warning messages over-reported usage by ~13
percentage points vs CC native /context. Root cause: gsd-statusline.js
wrote a buffer-normalized used_pct (accounting for the 16.5% autocompact
reserve) to the bridge file, inflating values. The bridge used_pct is now
raw (Math.round(100 - remaining_percentage)), consistent with what CC's
native /context command reports. The statusline progress bar continues to
display the normalized value; only the bridge value changes. Updated the
existing #2219 tests to check the normalized display via hook stdout rather
than bridge.used_pct, and added a new assertion that bridge.used_pct is raw.

The autocompact buffer percentage was hardcoded to 16.5%. Users who set
CLAUDE_CODE_AUTO_COMPACT_WINDOW to a custom token count (e.g. 400000 on
a 1M-context model) saw a miscalibrated context meter and incorrect
warning thresholds in the context-monitor hook (which reads used_pct from
the bridge file the statusline writes).
Now reads CLAUDE_CODE_AUTO_COMPACT_WINDOW from the hook env and computes:
buffer_pct = acw_tokens / total_tokens * 100
Defaults to 16.5% when the var is absent or zero, preserving existing
behavior.
Also applies the renameDecimalPhases zero-padding fix for clean CI.

When no in_progress todo is active, fill the middle slot of
gsd-statusline.js with GSD state read from .planning/STATE.md.
Format: <milestone> · <status> · <phase name> (N/total)
- Add readGsdState() — walks up from workspace dir looking for
.planning/STATE.md (bounded at 10 levels / home dir)
- Add parseStateMd() — reads YAML frontmatter (status, milestone,
milestone_name) and Phase line from body; falls back to body Status:
parsing for older STATE.md files without frontmatter
- Add formatGsdState() — joins available parts with ' · ', degrades
gracefully when fields are missing
- Wrap stdin handler in runStatusline() and export helpers so unit
tests can require the file without triggering the script behavior
Strictly additive: active todo wins the slot (unchanged); missing
STATE.md leaves the slot empty (unchanged). Only the "no active todo
AND STATE.md present" path is new.
Uses the YAML frontmatter added for #628, completing the statusline
display that issue originally proposed.
Closes#1989
