`cmdVerifyKeyLinks` compiled `must_haves.key_links[].pattern` from plan frontmatter with `new RegExp()` and tested it against whole file contents, so a nested-quantifier pattern such as `(a+)+$` hung `verify-phase` indefinitely (CWE-1333). JavaScript has no regex-execution timeout.
Untrusted patterns now run on RE2 (re2js), whose match time is linear in input length — the class is closed by the engine, not by a heuristic screen. The screen lost in the ADR-0174 consolidation was deliberately NOT restored: it never worked, since `(a|a)*$`, `((a+))+$`, `(a+){2,}$` and `(a{1,3})+$` all evade it. A refused pattern's matcher returns false for every input, so it cannot report a match no matter what the caller does.
The engine is vendored at gsd-core/bin/lib/vendor/re2js.cjs because gsd-core/bin/** is copied into installed trees with no node_modules; runtime dependencies are unchanged. New ESLint rule local/no-external-require-in-bin enforces that invariant, which had been documented in a comment since the #3024/#2071 bug class and enforced nowhere.
Backreferences and look-around are unsupported by RE2 by construction — disclosed in a Changed changeset.
Closes#3477
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
RegExp.escape is ES2026 (first shipped in Node 24); pattern.cts called it
unconditionally, and the build consumes the module
(scripts/gen-loop-host-contract.cjs), so npm run build failed on Node 22 and
the gsd-test linux-node22 lane could not reach run_tests.
Fix: prefer the built-in when present, else an in-file metachar escape —
still the sole owner of escaping (#3212 invariant; lint scope unchanged).
Builtin captured at module load so runtime mutation cannot flip the path.
Regression: tests/pattern.test.cjs section 4 — child-process probes neuter
RegExp.escape before/after require and assert match-behavior equivalence.

* test(#3468): add write-path drift guard, ratcheted at its measured baseline
Guard-first, per ADR-3180 Amendment 3's standing rule that a phase builds
and runs its guard BEFORE its scope is fixed, and states its copy count as
'N found by the guard', never 'N per the epic'.
Measured, not assumed:
Axis 1 (policy dispatch, ADR-3408 section 8.1) — 7 violations, RED by
design. 5 field-name-keyed getFieldClassification('literal') branches
plus 2 declared FieldPreservation members with no executor at all
(derive, clear). This is the fail-first evidence for the refactor.
Axis 2 (write seam, section 8.3) — 4 bypasses, ratcheted. Epic #3408
scoped this at two writers; the whole-repo scan found four, and one the
epic named (patchCore) is not among them because it bypasses via
stateReplaceField rather than the seam calls. Fourth consecutive time an
epic's copy count proved a lower bound.
Two detectors were written and removed again before this commit, both
recorded in the file header rather than silently dropped:
- A prompt-layer detector that reported 5 backticked prose mentions as
drift. That is ADR-3180 Amendment 3's recorded false-positive class,
and CONTRIBUTING.md already settles it: a backticked command reference
is a mention. Now gated on inline-code spans.
- A stateReplaceField co-occurrence detector for section 8.3(b). Measured
at 29 false positives to 1 true positive — it matched the function's own
definition and ~20 calls on frontmatter-free body slices. Banking 29
non-defects to catch one is the 'ratchet as a parking lot' gaming route
Decision 5 names, so it is a DECLARED KNOWN GAP owned by Phase 2
(#3469), which both fixes it and makes its detection tractable.
* test(#3468): failing-first coverage for policy dispatch and the loud failure
Matrix sections A, B and C from 50-test-matrix.md.
Expected RED against this tree, confirmed by static trace rather than
assumed:
B1, B2, B3 — an unwired declared preserve-when-unchanged row must throw
with code STATE_PRESERVATION_UNWIRED_ROW and a structured .field. Today
src/state-transition.cts:314 silently continues.
A4 — a whitespace-only snapshot is restored today, because the guard is
.length > 0. Required behavior is skip.
Everything else is characterization, locking in behavior the refactor must
preserve. C1 is table-driven over every FIELD_CLASSIFICATION key; C2 pins
current_phase_name's exact outputs as literals, because its row is being
reclassified preserve-always to preserve-when-unchanged as a
behavior-preserving change and nothing else would catch a drift. C3 is a
seeded fast-check property (seed 3468, 200 runs, replay data on failure).
A22 is deliberately NOT a behavioral test. Whether 'derive' has an explicit
executor is not observable through applyStatePreservation's public API — it
is a structural property, and the drift guard's unimplemented_policy axis is
what enforces it. That split is ADR-3408 Decision 5's own pairing: the lint
is the structural metric, the test is the outcome metric, and neither is
reported alone.
* refactor(#3468): dispatch preservation on the declared policy, not the field
Implements ADR-3408 sections 8.1, 8.2 and 8.6.
applyStatePreservation is now one loop over FIELD_CLASSIFICATION dispatching
on the row's preservation value, with four small executors — one per
FieldPreservation member. No branch is selected by field name. Zero
literal-argument getFieldClassification calls remain.
Behavior-preserving for 16 of 20 input classes. The four that change:
- An unwired declared preserve-when-unchanged row now THROWS
(code STATE_PRESERVATION_UNWIRED_ROW, structured .field) instead of
silently continuing. This fires only on an internal invariant violation
with both ends in our own source; a drifted, malformed or unparseable
user STATE.md must never reach it, which is section 8.2's bright line
and what test B8 proves through the real CLI.
- derive gained an explicit no-op executor. That is what makes the throw
decidable: 'policy says do nothing' is now distinguishable from 'nobody
wired this'.
- current_phase_name's row is corrected from preserve-always to
preserve-when-unchanged. The row was wrong, not the code — it has always
been delta-gated on the body Phase line, so preserve-always had two
divergent implementations. Behavior is unchanged and test C2 pins it.
- A whitespace-only snapshot is no longer restored; the check is trimmed.
clear is deleted from the FieldPreservation union — no row used it and no
executor existed. Speculative Generality: a policy invented for a need that
never arrived. Verified zero dependents.
The caller folds six dedicated pre/post parameters into one bodyDeltas map
keyed by field, so all seven preserve-when-unchanged rows travel one channel
instead of two. Two shapes for one kind of data is why the executor needed
per-field branches at all.
Also fixed, found while reviewing the refactor rather than deferred:
- applyPreserveIfPlaceholder opened with a field-name literal test, which
section 8.1 forbids outright. The executor is idempotent, so the test
bought nothing. The drift guard could not see it, so Axis 1 is widened
to catch field-variable comparisons against literals — the guard
reported zero while a violation sat in the file it polices, which is
Goodhart's gaming-by-indirection.
- loadBaseline conflated an unreadable baseline with an absent one. A
guard whose own diagnostic collapses two states into one identical
result reproduces the exact failure shape this epic exists to remove.
* docs(#3468): record Phase 1 validation as ADR-3408 Amendment 1
Amendment 1 records what Phase 1 found, per ADR-3408 section 8's rule that a
behavior it does not state is not decided:
- preserve-always had TWO divergent implementations; current_phase_name's
row was wrong and is reclassified, behavior unchanged.
- section 8.6 resolved: clear is deleted, zero dependents.
- the closed guard vocabulary is real and has exactly one true member,
because stopped_at's scoping turned out to be caller-side extraction.
- copy count found by the guard: 4 write-seam bypasses where the epic
scoped 2, and patchCore — one of the two it named — is not among them.
- two detectors built and removed again, with their measured false-positive
rates, so nobody re-attempts them.
- a DECLARED KNOWN GAP for section 8.3(b), owned by Phase 2.
- Decision 5's anti-gaming list earned itself twice in one phase.
Also adds the changeset fragment.
* test(#3468): fix review findings — try/finally, stale clear allowlist, ratchet owners
Standards axis, both hard violations:
- tests/state-write-path-drift-guard.test.cjs wrapped stdout/argv/exitCode
restoration in try/finally inside the test body. CONTRIBUTING.md:356
forbids it outright, and the correct t.after() pattern was already in
use two lines up in the same test.
- tests/state-transition.test.cjs still listed 'clear' as an allowed
FieldPreservation value in the row-enumeration test AND the
getFieldClassification property test, after this PR deleted it. A stale
allowlist weakens the property's negative space — it would accept a
resurrected clear row as valid.
Contract tension, resolved rather than left:
ADR-3408 section 8.3 requires each ratchet entry carry the issue owning
its removal. All four shipped with owner: null. The guard was right not to
INVENT one, but the owners are known from the phase plan, so recording
them is not inventing: phase.cts -> #3469, state.cts and milestone.cts ->
#3471, health-diagnostic.cts -> sanctioned-permanent.
Rather than a JSDoc caveat, --baseline now MERGES prior owner values on
the (file, source) key, so a mechanical regeneration can no longer
silently discard curated provenance. Verified by regenerating twice.
* fix(#3468): sanitize attacker-controlled fields on every guard output path
Isolated security review, MEDIUM, confidence 8/10.
findSeamBypasses and findPromptSeamUses built findings with an UNSANITIZED
`file`, while the co-located `source` on the same object was correctly
wrapped in sanitizeForReport. On a fork PR a filename is exactly as
attacker-controlled as a source fragment — a repo can legally track a
filename carrying C1 control bytes or bidi overrides.
The raw value reached two paths: --json stdout, and the COMMITTED baseline
JSON via buildBaselineEntries. JSON.stringify neutralizes C0 controls but
does NOT escape C1 (0x7f-0x9f) nor the bidi/zero-width range
sanitizeForReport exists to strip — which is the precise threat the guard's
own header names. Only the human formatter was safe.
Sanitization now happens at CONSTRUCTION, so every consumer inherits it
rather than each output path having to remember. The same defect was present
on `field` and `policy` and is fixed alongside. Double-sanitization in the
formatter is left in place, verified idempotent: escaped output is ASCII and
cannot re-match the control/bidi classes.
Also: the guard was not referenced anywhere in package.json, so nothing ran
it. A drift guard nobody runs is not a guard, and ADR-3408 Decision 5 assumes
it runs. Wired into lint:ci beside its sibling drift guards; it was already
green on this tree, so the chain stays green.
* chore(#3468): re-curate ratchet after an upstream rewording of a tracked bypass
The rebase onto origin/next turned the guard red on its first real day, which
is the ratchet working rather than a defect.
c90ae479f fix(#3350) reworded cmdPhaseComplete's syncStateFrontmatter call
onto one line and changed its third argument. Because entries are keyed on
(file, trimmed source text) rather than a line number, that single upstream
edit registered as BOTH a stale acknowledgment and an unrecorded site — the
two-sided signal the design intends, forcing a human to look rather than
letting a tracked bypass drift out of view.
The owner-preserving merge behaved exactly as designed: three owners survived
because their keys were unchanged, and phase.cts's dropped to null because its
source text is genuinely a different key. Re-curated to #3469, the phase that
owns its removal.
Note for Phase 2: c90ae479f is #3350's fix landing independently on next —
one of the two instances Phase 2 was scoped to drive fail-first. Surfaced to
the epic rather than absorbed silently.
* test(#3468): derive B1's fixture from the table so it cannot go stale
Checkpoint 2 came back with 2 failures of 33803, both B1:
actual 'current_phase_name'
expected 'current_plan'
The implementation was right and the test was stale. B1 hand-built a
bodyDeltas literal intending current_plan to be the ONLY unwired row, but it
also omitted status, stopped_at and current_phase_name — all three of which
became preserve-when-unchanged rows in THIS PR. Table order puts
current_phase_name first, so the throw correctly named it.
B1 now builds from neutralBodyDeltas() and deletes exactly one key, which is
what its own comment always claimed it did. A future table change can no
longer silently make it assert the wrong field.
Audited every other bodyDeltas literal in the file: four exist, all correct —
two enumerate all seven rows explicitly, two pass {} where the emptiness is
the point of the test. Roughly thirty other sites already derive from the
helper.
Also renames the local unchchangedChanged to lastActivityDescChangedDeltas.
A typo'd identifier that happens to work is still a Mysterious Name; noted
during research and fixed now that this change touches the file.
* chore(#3468): re-curate ratchet and fold the seam channel into the shared helper
The rebase onto be9329b10 fix(#3374) was a true semantic conflict, resolved
rather than handed back, because the resolution was determinable:
That PR extracted the post-sync preservation pass into a shared
applyPostSyncPreservation helper — which is ADR-3408 section 8.3, i.e. a
piece of Phase 2's own deliverable, landing upstream. Its structure is kept
wholesale; this branch's contribution is applied INSIDE it.
That combination had to be checked rather than assumed. Upstream's helper
wires only FOUR bodyDeltas keys and still passes status / stopped_at /
current_phase_name through six dedicated parameters. This branch reclassifies
current_phase_name to preserve-when-unchanged, deletes those six parameters
from StatePreservationInput, and makes an unwired declared row THROW. Taking
upstream's file as-is would therefore have thrown on EVERY STATE.md write.
The helper now wires all seven rows through the single channel. Verified
7-to-7 against FIELD_CLASSIFICATION, with a clean tsc — which is the real
proof the dedicated parameters are gone, since they no longer exist on the
input type.
The ratchet also caught the same phase.cts call being reworded a second time,
reporting it as both a stale acknowledgment and an unrecorded site. Re-curated
to #3469. Recording the tradeoff plainly: keying on (file, source text) means
an upstream reword of a tracked line needs re-curation, where keying on line
numbers would churn on every unrelated edit. ADR-3180 Decision 4(e) chose
source text deliberately, and the owner-preserving merge added earlier covers
the common case where the text is unchanged.
* chore(#3468): backfill pr number in changeset fragment
---------
Co-authored-by: sim <sim@local>
Phase 1 of #3464. Removes the `// allow-test-rule:` marker from 22 test files
where it is provably vestigial, and tightens the ratchet ceiling in
scripts/lint-allow-test-rule-refs.ceiling.json from 305 to 285.
Eligibility is decided by two independent AST discriminators, both
conservative (any doubt => keep):
(a) Read-target type. Every readFileSync/readFile call in the file resolves
statically to a prose/config extension (.md/.json/.yml/.yaml/.toml/.txt),
or the file performs no reads at all. Any read of a source extension
(.cjs/.js/.mjs/.ts/.cts/.mts/.jsx/.tsx), any dynamic/unresolvable path,
and any other extension all disqualify the file.
(b) Marker context. Every `allow-test-rule:` occurrence is a genuine comment
node, never string- or template-literal payload. A marker that lives
inside a RuleTester `code:` fixture is test DATA, not a suppression
directive; stripping it corrupts the test. tests/eslint-rules.test.cjs is
the one such fixture host and is deliberately untouched.
An earlier attempt at this phase classified markers by "strip it and see if
local/no-source-grep still passes" and was reverted in full before commit.
That oracle is unsound: the rule only fires on a literal .cjs/.js/.ts path
containing a quoted bin/lib/gsd-core/src segment, tracked one hop from the
binding, so files that genuinely source-grep real JavaScript pass it
silently -- tests/no-unbounded-spawn-allowlist.test.cjs (reads test sources
through a listTestFiles() walk) and tests/claude-imperative-reference.test.cjs
(matches bin/install.js through an intermediate variable) both cleared it
while being real source-greps. The rule's implementation is narrower than its
intent, so it cannot adjudicate whether an exemption is load-bearing.
Scope is limited to comment deletions: the diff over the test tree is 100%
line removals with zero insertions, and no executable line is altered.
On the ceiling value. The measured count at this HEAD is 283, so 285 leaves 2
slack -- deliberate, and well inside the documented grace band of 3. Pinning
the ceiling to the exact count makes this change effectively unmergeable: any
concurrent PR that lands one marker-bearing test file re-reds it. That race
fired twice while preparing this branch (once mid-rebase taking the count
304->305 on next, once between rebase and the verification run taking it
282->283), and it is the same race that broke next in #3461. A ceiling of
actual+2 preserves a merge window while still ratcheting 305 -> 285.
Known limit, disclosed rather than papered over: this clears 22 of 303
markers and does not reach #3464's trend-to-zero goal. Most of the remaining
markers sit on dynamic-path reads, commonly a hoisted `const p =
path.join(tmpDir, 'STATE.md')` whose target is prose but is unresolvable to
this classifier. A stricter one-hop const resolution would flip an estimated
95 more; that is deliberately left to a follow-up so it can be reviewed on
its own evidence.
Marker discovery reads bytes rather than shelling out to grep:
tests/security-prompt-injection.security.test.cjs carries a literal NUL byte
(an intentional injection fixture) that makes grep treat it as binary and skip
it, which is why the true marked-file count is 303 and not the 302 a shell
scan reports.

* fix(#3374): phase.complete stops harvesting stale body stopped_at
Variant A: cmdPhaseComplete's adapter calls syncStateFrontmatter directly
(deliberately - STATE.md commits atomically with ROADMAP/REQUIREMENTS),
which also bypassed the #948/#1230 preservation pass every RMW write gets.
A stale body 'Stopped at:' line then silently clobbered a fresher
frontmatter stopped_at on every phase completion, with warnings: [].
Three layers close it without reversing #3517's refresh expectation:
- completePhaseCore now refreshes the body continuity line it implies
('Phase N complete, ready to plan Phase N+1'; ADR-2207 phrasing on the
last phase), session-scoped via the new stateReplaceFieldInSession seam
so a decoy bold Stopped-at line in an unrelated section cannot absorb
the refresh. Replace-only - a layout with no session line keeps its
shape and its frontmatter value survives via the preservation delta.
- the RMW post-sync preservation chunk (snapshots + table-driven
applyStatePreservation + #2736 re-assert, full bodyDeltas wired) is
extracted into the shared applyPostSyncPreservation helper; the
phase.complete adapter and writeStateMd (milestone complete / state
sync - the gap the closed PR #3442 review flagged) now run it too.
- cmdStateRecordSession pushed 'Stopped At' onto updated[] on any label
MATCH, including a value already on disk - reporting a write that never
changed a byte. It now reports only on real change, and the match is
tracked separately so an identical value does not arm the #944 DWIM
section rewrite (which would reset an executor-authored resume file to
None).
* docs(#3374): backfill changeset pr field to 3491
* fix(#3374): drop the writeStateMd preservation pass - state sync's #905 contract is body-wins
CI on this PR caught what the closed PR #3442 review's MAJOR remediation
option (a) would have broken: state sync's #905 contract ('body annotation
beats existing frontmatter when both are present') is the opposite by
design - sync exists to re-derive frontmatter from the body. A blanket
applyStatePreservation pass on writeStateMd re-locked stale frontmatter
(current_phase 3 over the body's 5) on every sync.
Take the review's sanctioned option (b) instead: the scope claim is
accurate (phase.complete only) and the milestone complete / state sync
exposure is tracked as follow-up issue #3492.

* fix(#3384): strip mcp__* tool grants from zcode-installed subagents
ZCode's dispatcher treats every mcp__<server>__* entry in an agent's
tools: frontmatter as a required MCP server and hard-fails the subagent
spawn (CONFIGURATION_ERROR) when it is not connected, whereas Claude Code
treats the same grants as an optional allowlist. ZCode shared Claude's
verbatim agents copy (converter: null), so all 8 MCP-granted agents
failed to spawn out of the box with zero MCP servers configured.
Add convertClaudeAgentToZcodeAgent — a line-surgical converter that
filters mcp__* entries out of the frontmatter tools: grant list (both
inline comma and YAML block-list shapes) and preserves every other byte.
Declare it on both of zcode's capability.json agents entries and cut
zcode over to the descriptor-driven agents path
(_DESCRIPTOR_AGENTS_RUNTIMES) so the legacy inline loop stops
deleting+re-copying the converted agents raw. Claude Code, Kimi, and
Gemini install behavior is unchanged.

* fix(#3448): thread next_action through debug auto-resume respawn
Both /gsd-debug auto-resume call sites (Section 1c continue-path return
handling and Section 4's non-terminal branch) respawned the session manager
with identical session_params, making every resume prompt-indistinguishable
from a cold start: the checkpoint's recorded next_action and the disposition
that any earlier checkpoint was already answered never reached the respawned
agent. Two auto-resumes then made no progress and the (correct) no-progress
guard stalled the loop.
The respawn now carries resume: true, resume_status, and resume_next_action
sourced from the checkpoint file; the session manager documents the params
and its Step 2 gsd-debugger template forwards them via a DATA_START/DATA_END
<resume_directive> (Step 3d's shape), instructing the debugger to proceed
directly on the recorded next action without re-raising answered checkpoints.
The anti-loop guard (next_action-only heuristic, 3-resume hard cap) is
untouched.

withPlanningLock swallows a platformEnsureDir failure at src/planning-workspace.cts:210,
so an EACCES/ENOSPC/EROFS creating .planning/ is misreported as a 10s "held by a live

the corrected contract and currently fail against the unfixed source (RED). Also proves
the pre-existing Docker overlay-fs lock-write retry race is unaffected by this change.
* fix(#1884): surface mkdir failures instead of a phantom lock timeout
withPlanningLock swallowed platformEnsureDir failures (EACCES/ENOSPC/EROFS/EMFILE)
creating .planning/, so the subsequent lock write failed with ENOENT (parent
missing), which is retryable (PLANNING_LOCK_RETRY_ERRNOS, added for a Docker
overlay-fs race). The loop then spun the full 10s budget and threw a phantom
"held by a live process" contention error pointing at a nonexistent holder.
The mkdir failure now propagates immediately with its real errno and message.
The Docker overlay-fs ENOENT lock-write race (directory present) is unaffected,
as is every path where .planning/ already exists or is creatable.

* feat(#3415): ship local/no-unbounded-quantifier, burn down ReDoS class
Phase 4 of epic #3212 (ADR-3212 §5/§7, the final phase). New rule flags
an unbounded */+/{n,} quantifier over a broad character class
([\s\S], dotAll ., or a 1-2-unit negated class like [^\n]/[^)\n] — the
exact #2128-fixed shape) applied to a regex whose match target is
data-flow-traced to readFileSync content.
eslint-rules/lib/readfilesync-trace.cjs extracts the data-flow tracer
shared with no-crlf-fragile-split (Phase 2) rather than a second copy
— no-crlf-fragile-split refactored onto it with zero behavior change,
parity-tested.
Real triage, not 798 mechanical edits: the ADR's census (2026-08-08)
screened every unbounded quantifier in the tree unscoped. Correctly
scoped to readFileSync-derived content (matching Phase 2's own G2/G3
scoping), the rule found 162 real hits across two detection waves — the
second wave (93) surfaced only after a genuine off-by-one bug in this
rule's own first draft was caught while writing its RuleTester tests
and fixed (the bug silently missed every directly-quantified [\s\S]*
with no gap before the quantifier — exactly the class this rule exists
to catch). 3 hits landed in production src/ (commands.cts, milestone.cts,
roadmap.cts) and were each empirically timed against adversarial input
(matching #2128's own measured-not-assumed precedent) — all confirmed
linear-time/benign, left unbounded with a measured-evidence comment
rather than mechanically bounded. The remaining 159 are test-file
fixture parsing (test-author-controlled, fixed-size content, not
adversarial input) — each suppressed with a specific, non-generic
reason. Zero functional behavior changed anywhere in this diff.
tests/no-pending-3212-markers.test.cjs locks the epic's own closing
invariant (ADR §7: "assert zero pending #3212 markers remain") — ground
truth confirmed trivially true today (no phase left any such marker
behind), now regression-locked going forward.

* fix(#3415): correct rule category mislabel, add CI test-scope entry
An orthogonal Standards-axis review found eslint-rules/no-unbounded-quantifier.cjs

rule without realizing what that implied: docs/contributing/cross-platform-
portability-rules.md governs an ADR-1703 rule family under a hard "zero

PROTECTED_RULES bans eslint-disable for those rules entirely). This rule is
not part of that family — it's ADR-3212 (ReDoS/CWE-1333), a different epic —
and its eslint-disable-next-line suppressions (159 of them, added earlier
this same phase after empirical benign-verification) are an intentional,
correct design, not a bypass. Corrected to category: 'Best Practices',
matching the actual precedent (no-adhoc-regex-escape.cjs, Phase 1 of the
same epic, which is also correctly outside PROTECTED_RULES), and the rule's
own docstring now states this explicitly so a future reader doesn't have to
re-derive it.
Also registers a new scripts/ci-test-scope.cjs bucket so editing this rule
or the shared eslint-rules/lib/readfilesync-trace.cjs helper re-runs their
own test suites under targeted CI selection — was previously unregistered
and invisible to that fast-path (this PR's own gsd-test checkpoint runs the
full suite regardless, so this only affects future narrowly-scoped PRs).

* fix(#3415): bound no-unbounded-quantifier's own scanner (CWE-1333, ironic)
Security review found the rule meant to catch algorithmic-complexity bugs
had one of its own: hasUnboundedBroadQuantifier's negated-class inner
scan walked from each `[^` occurrence to the next `]` (or EOF) with no
bound, while the outer loop only ever advanced by one character — O(n²)
total work on a pattern with many unclosed `[^` runs. Runs unconditionally
inside checkPattern on any `new RegExp('literal string')` argument in any
linted file, before the (cheap) readFileSync data-flow gate — so a single
crafted string literal, no valid regex syntax required, could make
`npm run lint` / CI hang.
Empirically confirmed both the bug and the fix: pre-fix, n=4000/8000/
16000/32000 chars took 30.8/115.6/463.8/1874.3ms (~4x work per 2x n,
quadratic); extrapolated, the 300000-char repro from the finding would
run ~165s. Post-fix (bail the inner scan once units exceeds the rule's
own 1-2-unit scope, rather than continuing to hunt for a closing `]`),
the same 300000-char input runs in 8.7ms via the real rule module,
independently reconfirmed at 18ms via a fresh Linter.verify() call.
New regression row in tests/no-unbounded-quantifier.rule.test.cjs
asserts the RuleTester run on a 50000-char adversarial pattern
completes and returns a defined result — no wall-clock assertion
(CLAUDE.md Clock Seams / local/no-elapsed-assertion).

* fix(#3415): triage 3 new sites, re-raise ceiling after upstream batch
next merged 12 more PRs during this PR's review. Two consequences:
- tests/edit-phase.test.cjs (fix#3262, unrelated) added 3 new

workflow .md content — the same Class A pattern as the ~159 sites
already triaged elsewhere in this PR. Suppressed with the same
established reason.
- lint-allow-test-rule-refs' ratchet ceiling needed re-raising again
(301 -> 303) for the same reason as the two prior bumps: organic
growth from unrelated, already-reviewed PRs landing concurrently,
not a defect in this branch's own diff.

* fix(#3311): milestone lock makes parallel-phase state conflicts visible
Two sessions running different phases in one working tree silently
clobbered STATE.md's single un-scoped ## Current Position slot: byte-level
serialization already existed (STATE.md.lock since #464), but nothing ever
surfaced that two sessions claimed two different phases, and
state.advance-plan — which takes no phase argument — kept advancing whatever
plan the just-clobbered position named.
Adds the maintainer-chosen milestone lock (issue #3311 comment): an advisory
.planning/milestone.lock claim keyed by phase + session id (session identity
via getWorkstreamSessionKey: env-first, then controlling TTY). begin-phase
claims (inside the STATE.md lock), advance-plan detects a claim/position
mismatch and heartbeats a matching claim, phase.complete warns via warnings[]
and releases the claim when the claimed phase completes. Conflicts warn
(stderr + typed milestone_conflict JSON field) instead of blocking, per the
decision's blocking/warning latitude; TTL 4h with heartbeat liveness expires
abandoned claims. milestone.lock is registered in the canonical artifact
registry so validate.health W019 recognizes it.

* test(#1762): assert reassuring verification-routing wording (RED)
Regression test for #1762 — asserts readVerificationStatus's missing/
unknown next_action text reassures the user that execute-phase resumes
at the verification gates without redoing work, instead of reading as
a blind re-run instruction. Fails against current wording; the fix
lands in the next commit.
* fix(#1762): reassure verification-missing/unknown routing text is safe to run
readVerificationStatus's 'missing' and 'unknown' next_action text read as
"redo the implementation", when execute-phase's own discover_and_group_plans
step (#2868) already resumes at the verification gates and skips
execute_waves/checkpoint_handling entirely when every plan already has a
SUMMARY.md. Reword both to say so explicitly, and soften the 'unknown'
message to acknowledge a non-standard status may be an intentional marker
rather than presuming re-verification is always the fix.
Also updates progress.md's Route V.missing / V.unknown to consume the
dynamic $VERIFICATION_NEXT_ACTION (matching V.gaps/V.human) instead of a
hand-duplicated string, so the reassurance lands there too without a second
copy to keep in sync.
No change to next_command routing, status values, or the isPhaseComplete
completeness predicate (still gated on status === 'passed' per the #2957
DISK-STRICT decision) — advisory text only.
* fix(#1762): drop duplicated reassurance clause in progress.md routing text
Review finding: the SUMMARY.md reassurance was stated once via the
interpolated $VERIFICATION_NEXT_ACTION and again as a parenthetical on
the command line, in both Route V.missing and Route V.unknown. Trimmed
the parenthetical so $VERIFICATION_NEXT_ACTION stays the single source
of truth.
* docs(#1762): add changeset fragment
Type Changed with a docs-exempt marker — advisory routing text only,
no docs page documents this specific message today.
* test(#1762): acknowledge progress.md emitted-content growth
Route V.missing/V.unknown now render a small block referencing
${VERIFICATION_NEXT_ACTION} instead of a bare command line, growing
progress.md by 376 bytes. Deliberate per the differential attribution
check (ADR-2719).
* chore: drop spent progress.md ack from #3218's emitted-drift fragment
The #3218 growth it described is already on next (inert, per the
lint's own note that spent acks 'can no longer clear anything').
Its presence collided with the new #1762 fragment naming the same
bare filename, which lint-emitted-drift-ack rejects outright ('two
ack sources may never name the same path'). #3218's other two
acks (plan-phase.md, plan-review-convergence.md) are untouched.

* fix(#3191): anchor remaining diff-base greps, portably
The #2989 fix anchored only the Tier-3 grep, and did so with \b — not a
POSIX ERE token, so on macOS regex(3) it silently matches nothing and
Tier 3 always fails closed. spawn_reviewer's agent-context DIFF_BASE and
the fallow structural pre-pass's --changed-since base each still ran the
original unanchored --grep="${PADDED_PHASE}", whose oldest substring
match is routinely a version-string/date commit from months before the
phase existed — feeding the reviewer agent a bogus diff_base exactly
when files: is empty, and widening fallow's changed-files scope.
All three derivations now use the same anchored, POSIX-portable
'[Pp]hase N([^[:alnum:]_]|$)' with --extended-regexp; spawn_reviewer
also gains Tier-3's parent-exists guard so the two computations are the
same algorithm. Behavioral regression tests execute the shipped bash
extracted from the workflow files against a git fixture on every
platform, so the macOS \b hole is covered, not just the Linux CI view.

Three coupled defects in gsd-core/workflows/code-review-fix.md:

stayed at iteration 1 and contradicted the committed REVIEW-FIX.md. The
--auto commit now stages the converged REVIEW.md alongside REVIEW-FIX.md
(guarded on AUTO_MODE; non-auto single-pass runs unchanged).
- The two inline frontmatter validators (HAS_STATUS, FIX_FRONTMATTER)
exported REVIEW_PATH into a node -e body that reads process.env.
FIX_REPORT_PATH, so the status check was always empty and REVIEW-FIX.md
was never committed. Both now export FIX_REPORT_PATH.

* fix(#3188): null absent planning-doc paths in init phase queries
The init phase-op / plan-phase / execute-phase queries emitted a non-null
absolute requirements_path / state_path / roadmap_path even when the named
file did not exist — built with a bare path.join and no existence check,
unlike the conditional sibling fields (patterns_path, context_path, ...) in
the same payload. Consumers (e.g. ultraplan-phase.md:104 'requirements_path
is not null') therefore read missing files.
Each of the three reading sites now returns null when the file is absent and
its absolute path when present. The project/milestone-bootstrap and doc-ingest

intentionally unchanged.

* fix(#3171): init execute-phase emits display name, not directory slug
When a phase directory already exists on disk, the disk-lookup path
(searchPhaseInDir) derived phase_name from the directory-name remainder --
itself an already-slugified value (phase.add writes ${num}-${slug} dirs) --
so phase_name and phase_slug came out byte-identical. The execute-phase
workflow forwards phase_name into 'state begin-phase --name', which wrote
that raw slug into STATE.md's current_phase_name on every phase start.
cmdInitExecutePhase now prefers the ROADMAP's curated display name
('### Phase N: <Name>') for phase_name, matching the no-disk fallback path
that already did this correctly. phase_slug is unchanged (it feeds
branch-name construction). The state.begin-phase authoritativeFm override
(#2821/#2736) is untouched; the correction is in the value fed into --name.
The milestone_name half of #3171 was subsumed by #3216 / PR #3226; this

* feat(#3414): promote git-cmd.js token-walk into a shared scanner, fix#3169
Phase 3 of epic #3212 (ADR-3212 §4). New src/token-scanner.cts generalizes
hooks/lib/git-cmd.js's proven token-walk (#3129 — "has not re-opened"):
tokenizeShellLike (quote-aware shell tokenizer, byte-identical port) and
indentWidth (bullet-nesting depth).
git-cmd.js migrates onto tokenizeShellLike with zero behavior change
(parity-asserted against every existing #3129 fixture in
tests/worktree-safety.test.cjs's folded block); isGitSubcommand's phases
1-3 (env-prefix skip, executable check, global-option consume) extracted
into skipToSubcommand, shared with the new extractBranchArgument (git
checkout -b / git branch <name>) — a new capability exercising the seam
on the domain the ADR names, not a migration of existing duplicated logic
(none existed).
Fixes#3169: src/decisions.cts's parseDecisionLines couldn't distinguish
a cross-reference bullet nested under an open decision from a fresh
malformed declaration attempt. An earlier bold-run-content-classification
design was tried and disproven against the repo's own existing FIX-B
fixtures (D-02, "no colon no dash") before being adopted — both have
identical shape under any content-only rule. Nesting depth (via
indentWidth) is the actual distinguishing signal: a bullet indented
deeper than the currently-open decision's own bullet is elaboration,
folded into its text like a continuation line, never tested against the
parse-miss guard. A bullet at the same-or-shallower indent is unchanged.

fix is already a correctly-bounded regex per the ADR's own decidability
test (no scanner needed); #2528's fix is a deliberate, twice-reviewed
non-scanner design (its own code comment records a scanner-based attempt
that regressed a symmetric case and was reverted) that this phase does
not disturb. Only #3169 required new work.

* fix(#3414): add required fast-check property tests per code review
TESTING-STANDARDS.md:169 requires at least one fast-check property test
for any module that implements parsing — src/token-scanner.cts had none,
an orthogonal Standards-axis review finding. Adds two seeded property
tests (mirroring Phase 1/2's fast-check-setup.cjs convention):
indentWidth counts exactly a generated leading-space run; tokenizeShellLike
round-trips a generated array of whitespace/quote-free words joined with
single spaces.
The design doc's own "no property test needed" rationale was wrong — it
argued no algebraic law applied, but the standard is unconditional for
parsing modules regardless of whether one "feels" applicable. Corrected
in .gsd/phase/chore-3414-tokenizer-first-seam/50-test-matrix.md.
Also fixes two Spec-axis wording drifts the same review found between
the design doc and the shipped code (doc-only, no behavior change):
extractBranchArgument's documented signature dropped an unused
subVariants parameter that was never implemented, and the #3169
fail-first fixture description corrected from "15-decision plan via
cmdDecisionCoverageVerify" to the actual compact 3-decision analog via
the real blocking gate, check.decision-coverage-plan.

Claude Code applies SKILL.md effort: as output_config.effort; any change from
the session baseline invalidates the prompt cache at BOTH scope boundaries
(entry + exit, the latter often machine-fired via subagent-completion
notification). The reporter's owned measurement confirms it: /gsd-progress
(effort:low) in a medium session → cache_creation 63,404 (entry) + 18,589
(exit), while a no-effort skill shows none. ~76% of invocations paid in full.

* fix(#1526): delegate auto-chain post-completion to transition workflow
execute-phase's auto-chain completion called phase.complete then a light inline
set (partial PROJECT.md update + offer-next) and never invoked the transition
workflow, silently skipping graduation scan, session-continuity, project-reference,
accumulated-context, and current-position updates — so a phase completed via
auto-chain left different project state than a normal transition.
Fix (delegate, user decision 2026-08-13): replace execute-phase's update_project_md
+ offer_next with a delegation step that @-includes transition.md in post-completion
mode. Add a post_completion_mode step to transition.md that skips verify_completion
+ update_roadmap_and_state (phase.complete already ran; avoids double-write) and
begins at evolve_project. Standalone transition (mode 1) is unchanged.
Regression: tests/auto-chain-transition-delegation.test.cjs (source-text-is-the-
product) asserts the delegation, the skip-set, the removed inline step, and the mode.

* test(#3413): failing-first suite for the line-terminator seam
Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Tests only — src/text-lines.cts
does not exist yet, so tests/text-lines.test.cjs fails with MODULE_NOT_FOUND
at its require line, which is the intended RED.
The frontmatter.test.cjs additions drive #3360 (confirmed-bug) fail-first:
parseMustHavesBlock currently returns [] for every must_haves block on a
CRLF-authored plan file, because \r is its own LineTerminator in ECMAScript
and two /m-anchored \s* patterns can absorb it, inflating a captured indent
by one character and tripping the "not nested under must_haves" guard.
Verified locally against the current (unfixed) compiled module: both the
direct repro and the silent-exit "blank line before must_haves:" variant
return [] today. A parity property test (crlf vs lf must deep-equal for
every block name) matches a pattern this maintainer has required repeatedly
for prior CRLF fixes in this codebase (Cortex-recorded, verify_intent=held).
The no-crlf-fragile-split.rule.test.cjs additions lock the eslint rule's
future fix-hint text (pointing at splitLines()) and its self-reference
non-violation (the seam's own correct \r?\n split must never flag itself).

* chore(#3413): src/text-lines.cts owns line-terminator handling
Phase 2 of epic #3212 (ADR-3212 §3/§6/§7). Adds splitLines/normalizeEol/
detectEol/joinLines and migrates frontmatter.cts onto it.
parseMustHavesBlock (#3360, confirmed-bug) returned [] for every
must_haves block on a CRLF plan file. Root cause: \r is its own
LineTerminator in ECMAScript, so under /m two \s*-anchored indentation
lookups could match at the position INSIDE a \r\n pair and absorb the
terminator, inflating the captured indent by one character and tripping
the "not nested under must_haves" guard. Two silent exits, one with a
diagnostic and one without (a blank line before must_haves: hits the
silent path). Fixed by converting both lookups from a whole-string /m
match to split-then-scan — splitLines first, then a per-line, non-/m
match — the same structural pattern parseYamlRegion (30 lines away in
the same file) already used safely. Nothing downstream of the two
lookups changed; blockLines is now sliced from the already-split array
instead of re-splitting a substring, but its contents are unchanged for
LF input, and the per-line dash/kv parsing loop is untouched.
A parity property test (CRLF and LF plans parse to identical must_haves
for every block name) matches a pattern this maintainer has required
repeatedly for prior CRLF fixes in this file's neighborhood (Cortex:
7 recorded decisions, verify_intent -> held).
frontmatter.cts's other .split(/\r?\n/) call sites (parseYamlRegion,
isFrontmatterShaped, sliceTopLevelFrontmatterSegments, spliceFrontmatter)
are rerouted onto splitLines — a literal 1:1 substitution, zero behavior
change, since splitLines IS that same regex plus a type guard.
The 4 scripts/normalizeLineEndings copies (gen-registry, gen-loop-host-
contract, gen-capability-registry, gen-context-index) are deleted and
rerouted onto normalizeEol, which strips a bare unpaired \r exactly like
the deleted copies did (not just \r\n pairs) -- verified against each
script's own --check mode against its real generated output.
local/no-crlf-fragile-split widens from tests/ to src/**/*.cts, with its
fix-hint message now naming splitLines() instead of the raw regex --
the prohibition finally has a primitive to point at. Detection logic
unchanged in this phase (deliberate scope limit, see design doc Known
limits: the rule doesn't yet recognize safeReadFile/platformReadSync as
a content source, and has no detector for the \s-adjacent-to-anchor
shape that is #3360's actual mechanism -- the CLASS is converged by the
direct fix + regression test regardless).
joinLines/detectEol are NOT wired into frontmatter.cts's own write path
(cmdFrontmatterSet/Merge -> platformWriteSync) -- verified that
platformWriteSync already, unconditionally converts CRLF->LF on every
.md write today as a pre-existing policy owned by a different module,
and ADR-3212's backward-compatibility clause rules out a file-format
change in any phase. Stated explicitly in Known limits rather than left
for a reader to discover.

* fix(#3413): fix 13 pre-existing CRLF-fragile splits the widened rule found
Widening local/no-crlf-fragile-split from tests/ to src/**/*.cts (the
previous commit) immediately surfaced 13 real, pre-existing violations
across 10 files -- undetected until now because the rule never scanned
src/. This is the exact defect class ADR-3212 exists to close, playing
out again one phase after Phase 1 hit the same shape ("the new lint
rule -- once live -- found 27 more"). Per CLAUDE.md's no-defer rule,
fixed inline rather than deferred or suppressed; there is no
established suppression convention for this rule in src/ and inventing
one now would undermine the point of widening it.
audit.cts, broken-windows.cts, core-utils.cts, init.cts, milestone.cts,
phase.cts (x3), profile-output.cts, roadmap.cts (x2): bare-\n splits or
regex character classes widened to \r?\n / [^\r\n], each following the
same pattern already established migrating frontmatter.cts.
phase-estimation.cts: `\r?(?:\n|$)` restructured to `(?:\r?\n|\r?$)` --
already semantically CRLF-safe, but the rule's lexical scanner doesn't
recognize \r? guarding a group (only \r? immediately before a literal
\n). Verified the two forms are equivalent across all four EOL/EOF
cases before restructuring, not assumed.
roadmap-upgrade.cts needed two coupled sites, not the one flagged line:
computeMigrationPlan and applyMigration must agree on line
representation for the lines[edit.lineIndex] === edit.from equality
check to hold, and the write-back needed joinLines + detectEol -- a
plain lines.join('\n') was silently flattening a CRLF ROADMAP.md to LF
wholesale on every migration. This is the first real production
consumer of joinLines/detectEol in this epic (frontmatter.cts's own
write path doesn't use them -- see the previous commit's Known limits).
Fixing the 13 flagged sites surfaced 4 more adjacent same-shape sites
the rule doesn't track (.search() and new RegExp(dynamicString) aren't
in its tracked call/construction set). Investigated each empirically --
hand-tracing this exact bug class already produced one wrong conclusion
earlier in this phase (a detectEol design-doc arithmetic error), so
these were verified with real CRLF fixtures rather than reasoned about
on paper:
- audit.cts (scanTodos): REAL bug, fixed. `bodyMatch.trim().split
('\n')[0]` leaked a trailing \r into a user-visible todo summary on
CRLF input -- .trim() only strips the string's outer edges, not a
\r sitting mid-string before the first bare \n. Now splitLines(...)
[0].
- phase.cts (cmdPhaseInsert, bullet-style branch): REAL bug, fixed.
[^\n]* in targetBulletPattern swallowed a line's trailing \r on
CRLF input, shifting the computed insert position to land INSIDE
the \r\n pair; combined with a hardcoded '\n' bullet separator, a
CRLF ROADMAP.md ended up with a mixed CRLF/LF result after an
insert. Fixed with two coupled changes (either alone still
corrupts, verified both ways): [^\r\n]* in the pattern, and the new
bullet's leading terminator now comes from detectEol(rawContent).
- roadmap.cts (cmdRoadmapAnnotateDependencies phase-boundary scan):
investigated, genuinely safe, left untouched. The .search(/\n#{2,4}
.../) boundary-finder and the [^\n]*-based heading match were
empirically verified on a 3-phase CRLF fixture -- the only stray \r
ends up at the tail of an intermediate phaseSection string that is
only ever used for .test()-based idempotency checks, never for an
exact-match comparison or written back to disk. No corruption on
round-trip.
Every fix re-verified: npm run build:lib clean, npx eslint
'src/**/*.cts' --no-cache reports 0 problems (was 13), and each
fixed function's existing LF-input tests were spot-checked unchanged.
* fix(#3413): apply orthogonal review findings
Two isolated review engines (correctness + security) ran against the
full diff and found three majors, one real security issue, and several
disclosure-worthy minors. All fixed or explicitly disclosed with
evidence; nothing deferred.
MAJOR — detectEol's tie-break contradicted its own documented contract.
Code returned '\n' on a 1:1 crlf/bare-LF tie; every doc (design doc,
CONTEXT.md, the function's own comment) says ties resolve to '\r\n'.
The existing test masked this by reusing the same tie fixture the
buggy code happened to satisfy, rather than a genuine LF-majority
case. Root cause: an Edit attempted earlier in this phase to fix this
exact arithmetic error was blocked by the tier guard, and a later
dispatch was incorrectly told it had already landed. Fixed: condition
is now crlfCount >= bareLfCount; the test fixture corrected to a
genuine 2:1 majority, with a new explicit tie-case test.
MAJOR — phase.cts's cmdPhaseInsert built an EOL-aware bulletEntry via
detectEol(rawContent), justified by a comment claiming a hardcoded
'\n' corrupts a CRLF ROADMAP.md. False: this write goes through
platformWriteSync, whose normalizeContent/_normalizeMd unconditionally
converts CRLF->LF for any .md target — the templating was inert dead
code, erased before the file is ever written. Reverted to hardcoded
'\n', comment corrected to state the true reasoning. The separate
[^\n]* -> [^\r\n]* widening one function up (a real splice-position
fix, independent of final EOL) was kept.
MAJOR — roadmap-upgrade.cts's stated rationale for switching onto
splitLines/joinLines was wrong (both functions always agreed on line
representation, before and after — the claimed equality-check risk
never existed), and the change it justified introduced a real
regression: forcing every line onto one dominant terminator silently
rewrites untouched lines' EOL on a mixed-CRLF/LF ROADMAP.md. This
write path uses raw fs.writeFileSync, not platformWriteSync, so unlike
the phase.cts case above the regression is genuinely live.
Fixing this took two attempts. The first attempt (revert to
split('\n')/join('\n') plus a suppression comment) was correctly
blocked by an agent that discovered local/no-crlf-fragile-split is a
PROTECTED_RULES entry in tests/portability-rule-disable-ban.test.cjs —
a hard, out-of-band, ADR-1703-governed guardrail banning any
eslint-disable of this rule anywhere in src/**/*.cts. That agent also
detected and correctly disregarded an injected instruction that
appeared in tool output during a git operation, per this session's
untrusted-content policy. The actual fix: computeMigrationPlan
reverted to roadmapContent.split('\n') (confirmed lint-clean — the
rule's data-flow tracking only follows a variable's initializer, and
this one is declared empty then reassigned in a try block).
applyMigration's write-back now splices edits against the ORIGINAL
content string via indexOf('\n', pos) boundary-walking instead of a
full split/rejoin, so every untouched character — including every
line's own terminator — is copied byte-for-byte. A capture-group split
(/(\r\n|\n)/, preserving terminators inline) was tried first and
empirically confirmed to still trip the rule before this approach was
chosen instead.
MINOR (security) — roadmap.cts's cmdRoadmapAnnotateDependencies used
the STRING form of String#replace, so $&, $`, $', $1-$9 inside
must_haves.truths content (author-controlled) were interpreted as
replacement directives, splicing unrelated ROADMAP.md text into the
result. Fixed with the function-replacement form, which is never
pattern-interpreted. Verified before/after with the reviewer's exact
repro.
Also disclosed rather than silently left: test matrix row 31 (four
planned CRLF-materialized regression tests) was never implemented as
separate files — corrected to record the actual verification (a
manual --check run plus incidental existing coverage via each script's
normalizeLineEndings: normalizeEol alias). parseMustHavesBlock's LF
behavior was claimed byte-for-byte unchanged but the old
yaml.indexOf(blockMatch[0]) substring search could match an unrelated
earlier occurrence of the header text (e.g. inside a quoted value) —
the split-then-scan fix incidentally also closes this, a strict
improvement now recorded in the design doc rather than left implicit.

* fix(#3413): checkpoint 2 red — missing eslint ignore entry, RuleTester config error
Checkpoint 2 came back red with 5 failures on the reviewed sha, both
gaps genuinely undetectable by any local gate.
eslint.config.mjs was missing the 'gsd-core/bin/lib/text-lines.cjs'
ignores-list entry (ADR-457: generated .cjs artifacts are excluded from
direct type-aware linting). Phase 1's sibling entry (pattern.cjs) sits
two lines above it and was the exact precedent read while researching
the six-gate ripple for this module -- missed anyway. Caught by
tests/repo-invariants.test.cjs's bin/lib coverage-tracking test, which
only runs on the remote suite.
tests/no-crlf-fragile-split.rule.test.cjs's row-32 case specified both
`messageId` and `message` on the same RuleTester error assertion --
ESLint's RuleTester rejects that combination outright. This existed
since the test was first authored and was never caught locally: `npx
eslint` only lints the file's syntax, it does not execute RuleTester,
and local `node --test` is hard-blocked in this repo -- the assertion
had never actually RUN before this checkpoint. It was even present in
checkpoint 1's failure list, listed there as one of the "expected RED"
tests; I matched it against my expected-failures list by test NAME
only and never inspected the actual failure detail closely enough to
notice it was failing for the wrong reason (a RuleTester config error,
not the intended message-text mismatch). Fixed by keeping `message`
(the exact-text assertion the test exists to make) and dropping
`messageId`. Verified the crlfFragileSplit message string in
eslint-rules/no-crlf-fragile-split.cjs matches this assertion
character-for-character, and swept every other invalid case in the
file for the same double-specification bug (none found -- all
pre-existing cases use messageId alone).

* docs(#3413): add Fixed changeset for the #3360 CRLF parsing fix
The sole user-visible effect of this phase. No breaking-change label
or Changed fragment needed — ADR-3212's Backward Compatibility section
names the Node floor (Phase 1, already shipped) as the epic's only
breaking change; Phase 2 has none.
* chore(#3413): backfill changeset pr number to 3420

expectedQuickId() in tests/init.test.cjs computed its expected quick_id
using local-time Date getters (getFullYear/getMonth/getDate/getHours/
getMinutes/getSeconds) in the test-runner process, while the CLI
subprocess under test is pinned to TZ=UTC. The two sides only agreed
when the test-runner's own ambient TZ happened to already be UTC.
Swap the six getters to their getUTC* equivalents so the helper is
timezone-invariant. No change to src/init.cts (the CLI side already
relies on its own UTC-pinned subprocess env and is correct) and no
change to the pinned clock instants or expected quick_id strings
asserted by the three affected tests.
Introduced by 80734a969 (#3332).
