bbdf7e8e84 chore(#4654): add local/no-unconfined-path-join and drain it to zero — Phase 4 of #4636 (#4674)
* chore(#4654): add local/no-unconfined-path-join and drain it to zero

Phase 4 of epic #4636 — the ratchet, and the phase that makes the epic hold.

THE MEASUREMENT THAT RESHAPED THE PHASE. An AST census (the repo's own parser,
not grep) found what the epic never enumerated: ADR-4650 named seven containment
implementations; `src/` alone held roughly 24 more hand-rolled gates across ~13
files, several guarding a write or an `fs.rmSync`. Two verified by reading rather
than pattern-matching — `research-store.cts` comments its own as "ensure the
resolved file path stays inside the store dir" immediately before a write, and
`capability-lifecycle.cts` gates `fs.rmSync` with one.

So the epic's Done-when "one containment predicate, used at every site" was FALSE
when Phase 3 reported it satisfied. It is true now: the rule is clean across
src/, scripts/, gsd-core/bin/ and hooks/ with an EMPTY allowlist.

WHY NOT THE RULE THE ISSUE PROPOSED. #4654 proposed flagging `path.join` whose
first argument is a managed root and whose later arguments derive from argv. That
is a taint analysis over 2046 call sites, in ESLint, without type information;
"derives from argv" is not locally decidable. Any approximation either floods or
is trivially evaded, and a rule that fires on hundreds of correct sites earns an
allowlist of hundreds — the opposite of a ratchet. What is actually duplicated is
the COMPARISON, not the join, and that has one recognizable shape.

  Arm 1  X.startsWith(Y + sep)            the hand-rolled containment idiom
  Arm 2  a containment predicate called as a bare statement, answer discarded

Arm 2 is the issue's "asserts the result was narrowed, not merely that a helper
was called". Its example `validatePath(x, root).resolved` is already
structurally impossible — Phase 3 un-exported `validatePath` — so the remaining
expressible failure is ignoring the answer, which is the defect that recurred
five times in this epic. The census found exactly one live instance
(`milestone.cts:1643`); it now returns the proven `ContainedPath` so consumers
stop re-deriving the path the comment above it was extracted to stop them
re-deriving.

The rule deliberately does NOT try to catch validate-one-path-use-another where
the answer is used but a different variable flows onward. That needs flow
analysis; the branded `ContainedPath` from Phase 3 is the defense there, and the
two are complementary.

PER-SITE FAMILY CHOICE, NOT A DEFAULT. Phase 3's lesson binds: collapsing a
lexical site onto the realpath family broke four tests and was caught only by the
matrix. Every migrated site was triaged individually. The six
installer-migrations tree-walks and the six capability-lifecycle gates take the
LEXICAL family because their operands are already realpath-resolved and they
deliberately treat the final component as a link; boundary sites take realpath.

TWO SITES WITH AN INVERTED CONTRACT, which a mechanical swap would have broken.
`installer-migrations.cts:127` and `runtime-artifact-install-plan.cts:144` REJECT
`target === root` by contract, while the canonical comparison ACCEPTS it. Swapped
naively, a migration could `rmdir` the user's config root and a third-party
descriptor could write at configHome itself. Both keep `=== root` as an explicit
additional arm alongside the predicate call — the predicate decides containment,
the call site keeps its own extra condition (ADR-4650 decision 6).

ONE DUPLICATE DELETED OUTRIGHT: `planning-inspect.cts`'s `isWithinRoot` was
byte-identical to `isContainedIn` and said so in its own docstring.
`isContainedIn` is now exported for callers that have already resolved both
operands and need only the comparison, with a doc note that a caller which has
NOT resolved them must use a full predicate instead.

THE MARKER, AND WHY IT IS NOT THE ALLOWLIST. Nine sites are justified holdouts and
carry `// allow-handrolled-containment: <reason>` with a mandatory, reviewable
reason. Two justifications: (a) not a containment decision — an ancestor-walk loop
condition, sub-repo grouping, worktree identity matching, declared-path coverage;
(b) it IS containment but the canonical predicate is unreachable —
`capability-validator.cjs` is a committed pre-build `.cjs` and the compiled
`security.cjs` is untracked build output, so requiring it would break a fresh
clone. `scripts/lib/drift-scan.cjs` runs under `lint:ci` with the same exposure.
The marker was renamed from `allow-lexical-prefix-match` mid-phase because that
name asserted only (a) and would have stated something false at the (b) sites.

A marker suppresses BEFORE the violation counter increments, so a file whose
every occurrence is marked still reports `staleAllowlistEntry` — otherwise a
drained entry lingers and silently re-permits the site later.

DEMONSTRATED RED, per #4654: a hand-rolled copy reintroduced into a real `src/`
file made `npm run lint` fail with the rule's full guidance message; removing it
returned the tree to clean. Both halves recorded — red alone proves nothing,
since a rule red for an unrelated reason looks identical.

DISCLOSED: `defaultRequireFromInstallRoot` (gsd-tools.cjs) previously carried two
distinct rejection messages and two manual realpath calls; routing it through
`tryWithinRoot` collapses them to one message, and a missing module now surfaces
as MODULE_NOT_FOUND rather than ENOENT. No test asserts either message. The
security property is preserved and slightly strengthened — the candidate is
realpathed and containment re-checked, and the dangling-symlink oracle closure
comes along with it.

* docs(#4654): record the containment ratchet in CONTEXT.md and the security model

Both entries previously described the seam without the thing that keeps it a
seam. They now state what the rule bans, and — more usefully for whoever reads
this next — what it deliberately does NOT attempt: deciding per path.join call
whether an argument came from user input. That question is not locally
decidable, and an approximation across ~2000 join sites would earn an exemption
list of hundreds, which is the opposite of a ratchet.

Also records the marker's two legitimate justifications and that its reason is
mandatory, so the escape stays reviewable rather than becoming a mute button.

Glossary gate 270 refs exit 0; install-tree goldens and CONTEXT-INDEX.json
regenerated and confirmed byte-identical rather than assumed — which also
confirms eslint-rules/ is not a shipped path.

* fix(#4654): close review findings and the two matrix failures

MATRIX FAILURE 1 — a collapsed message broke a negative-proof test, and my
evidence for collapsing it was wrong. I searched tests/ for the literal string
"resolves outside its install root", found nothing, and reported that no test
asserted it. The test matches a REGEX SUBSTRING, /outside its install root/, so
the literal search missed it. What broke was "NEGATIVE PROOF: a symlinked module
pointing OUTSIDE the install root is not loaded" — the test guarding the exact
property I claimed was preserved. defaultRequireFromInstallRoot now does both
checks again with both messages byte-identical, each routed through the
canonical predicate, which is better than the original since that hand-rolled
both comparisons.

MATRIX FAILURE 2 — shipped migrations are checksum-locked, and a marker cannot
serve there. migrationChecksum hashes plan.toString(), which INCLUDES comments,
so a suppression marker inside a plan body drifts the baseline exactly as an
edit does. Measured: with markers in place, two of the four still differed from
their committed checksums. The four shipped bodies are now byte-identical to
next, and the rule's config excludes those four paths BY NAME rather than by a
directory wildcard, so a NEW migration is still covered. Six containment
comparisons stay un-ratcheted there; that gap is recorded in the rule's Known
gaps, in CONTEXT.md and in the security model rather than left implicit.
Justification (c) is removed from the marker's documented reasons, because a
marker was proven unable to express it.

ADVERSARIAL REVIEW — the sharpest finding was that the rule banned the CORRECT
shape while permitting the incorrect one: startsWith(root) with no separator is
the genuinely unsafe form, since it accepts a sibling such as root-evil, and my
own test blessed it as valid. Flagging every bare startsWith would swamp the
rule, so that stays a STATED gap rather than a silent one. Closed for real: the
template-literal spelling, which the census never saw because it only inspected
plus-concatenation — that surfaced TWELVE more sites, now triaged and migrated.
A separator reached through a const alias is now resolved via scope analysis.
And isContainedIn, exported in Phase 3, was missing from the discarded-result
set, so a bare no-op call went unflagged on the one function the epic funnels
through.

SECURITY REVIEW — the marker could over-suppress two ways: a block comment
worked identically to a line comment, and one marker silently covered every
violation sharing its line. It now requires a Line comment positioned after the
flagged node ends, so it anchors to the node it trails. Four sites had dropped
an unreachable-but-deliberate equality rejection against the root; each is
restored as the call site's own arm. eslint.config.mjs still documented the OLD
marker token, which my rename missed — it would have sent the next author in
circles.

A FALSE GREEN, recorded because it nearly stuck: lint:ci reported exit 0 from a
stale eslint cache while twelve real violations existed. Every lint check here
now clears the cache first.

* fix(#4654): anchor a suppression marker to the violation it actually trails

The matrix caught this; my own test caught it, on its first execution. The case
"two violations on one line: trailing marker suppresses only the one it trails"
expected 1 error and got 0 — both were suppressed.

ROOT CAUSE: the anchoring accepted any Line comment on the node's line whose
range started at or after the node's end. A trailing marker at the END of a line
sits after EVERY node on that line, so that condition held for all of them.
"After the node" does not identify WHICH node the marker trails. The fix reads
as correct and is not.

FIX: deferred reporting. Violations accumulate during traversal instead of being
reported immediately; at Program:exit each marker claims exactly ONE pending
violation — the one on its line whose end is nearest before the marker begins —
and every unclaimed violation is then counted and reported. One marker, one
suppression. An earlier violation sharing the line is still reported, which is
the property the security review asked for and the previous attempt only
appeared to deliver.

The counter now increments at flush time rather than during traversal, so a
suppressed occurrence still does not keep an allowlist entry alive.

AND A TOOL THAT SHOULD HAVE EXISTED BEFORE THE FIRST MATRIX RUN. `node --test`
is hard-blocked here, so this rule's test file could only ever be executed on
the remote matrix — which is why a broken anchoring shipped into a run. ESLint's
programmatic Linter API is not a test runner, and exercising the rule through it
verifies every case locally in seconds. All 24 now pass locally, including the
two-on-one-line case that failed remotely. That loop should have been built
before the rule was first sent to the matrix rather than after it failed twice.

* chore(#4654): backfill PR 4674 into the changeset and complete 70-docs.json

The phase gate requires enablementSequence and the Diataxis quadrants; 70-docs
now carries both, with the how-to quadrant skipped for a stated reason rather
than an empty field. The audience for this deliverable is a contributor who
trips the rule, and the task-oriented guidance reaches them in the ESLint
message itself — which names the correct predicate, says how to choose between
the realpath and lexical families, cites the Phase 3 regression caused by
choosing wrong, and gives the marker syntax. A docs/how-to page would be a
second, driftable copy read by nobody at the moment of failure.

enablementSequence is recorded as what it actually is: a VERIFICATION sequence,
not an enablement one. The rule is never off, so there is no off-to-on
transition to describe.

scripts/lint-docs-required.cjs now passes (ok_docs_updated) — it could not
evaluate against the mandated pr:0 placeholder.

7e7a239a65 refactor(#4653): replace the allowAbsolute flag with a named acceptance policy
Phase 3 of epic #4636, stage 3b. Satisfies #4653's criterion that
`opts.allowAbsolute` become "a named acceptance policy on the predicate, not a
per-call-site boolean".

The flag was actively misleading at the call site. `{ allowAbsolute: true }`
reads as "containment is relaxed here". It never was: an absolute path that
resolves outside the root is rejected exactly as a traversal is. The flag only
ever controlled whether an absolute candidate was CONSIDERED. On a security
predicate that is the wrong thing for a reviewer to have to infer, and 31 call
sites were asking them to infer it.

    PathAcceptance.RelativeOnly         relative candidates only
    PathAcceptance.AbsoluteInsideRoot   absolute accepted, containment unchanged

The three exported wrappers take the policy and translate it inward.
validatePath keeps its internal `{ allowAbsolute }` opts and its body untouched —
the engine is not re-derived here either, only the exported surface is renamed.

MEASURED, NOT ESTIMATED. 31 call sites across 10 files, counted by walking the
AST with the repo's own @typescript-eslint/parser rather than grepping: a text
match would have folded in the options-type declaration, default parameter
values and comments. All 31 pass the literal `true`; none passes `false` or a
dynamic value, so the migration is uniform and `RelativeOnly` is purely the
existing default made nameable. audit.cts alone holds 18 of them.

This migration is compiler-verified in a way the containment-value migration in
the previous commit was not: the parameter type changed from an object to a
string union, so any missed site is a build error rather than a silent
behavioral difference. That is why a 31-site mechanical edit is acceptable in
the phase whose stated risk is the width of mechanical change.

1a358ce0fd feat(#2761): bracket-tolerant read path — roadmap/validate/verify/state recognize bracket ids (epic #612 PR-2) (#2867)
* feat(#2761): gated heading-intro selection + one bracket identity grammar

Foundation. Two owner-level changes plus a federated convention resolver; no
reader consumes them yet.

1. GATED SELECTION, not an ungated widening.

   Widening every heading matcher requires the claim "no legacy ROADMAP contains
   a `[CODE.MM]` bracket followed by a digit", and that is false:
   `### [RFC.2119] 5:`, `### [v1.0] 2024:`, `### [ADR.612] 3:` and
   `### [ISO.8601] 2026:` are ordinary headings, and a widened reader claims each
   as a phase — moving phase_count and total_phases and adding W006 on projects
   that never opted in. No narrowing rescues it: the premise is about documents
   we do not control.

   `phaseHeadingPrefixSrcFor(baseline, convention, capturing?)` selects the
   pattern SOURCE at construction time. A project whose resolved
   `phase_id_convention` is not exactly 'bracket' compiles the same source string
   it compiled before. `baseline` is explicit because whether a site spells the
   any-bracket prefix or a bare `Phase\s+` is a fact about that site's history:
   handing the wider grammar to a bare site retro-grants tolerance it never had,
   in both directions — warnings appear, and a warning that fires today vanishes.

   Both bracket forms CAPTURE. `[GSD.999] Phase 07:` previously matched through
   the base alternative, which captures nothing, so a reader saw no bracket, fell
   back to the legacy token rule, and counted a labeled icebox heading while
   excluding the label-less one beside it — two derivations of one ROADMAP
   disagreeing.

2. ONE bracket identity grammar, one width rule.

   The milestone width is reconciled with the emit validator: pad2 output, so
   two digits or 3+ with no leading zero. Earlier spellings diverged in both
   directions — admitting `002`, which the validator rejects, and a bare `0` pad2
   never produces — and the section recognizers accepted `[GSD.2]`, which SCOPED
   a milestone no phase heading could then resolve into, recreating the
   on-disk-count fallback this epic removes. An unpadded bracket is now uniformly
   malformed: it scopes nothing, bounds nothing, sections nothing. W005 on its
   directories is the surfacing signal.

   The milestone field is boundary-anchored, so a malformed run cannot match by
   its prefix (`GSD.002-01` read as sentinel `00`). Recognition stays
   case-insensitive because readers compile `/i`, but identity helpers match
   `[A-Z]`, so a captured id is folded first — otherwise `### [gsd.999] 07:`
   failed every sentinel test. The qualified key shares the width, the `(?=-|$)`
   boundary and the single-sub-phase shape of the directory token, because
   phaseTokenMatches returns unconditionally on a qualified hit: a key matching a
   directory isPhaseDirName rejects would be a final wrong answer.

3. resolvePhaseIdConvention federates workstream -> root exactly as
   config-loader does — including that root is a fallback only when a WORKSTREAM
   is active, so a project-scoped directory stands alone. loadConfig cannot serve
   this: it merges against CONFIG_DEFAULTS and drops keys it does not know, and
   this key is not among them. It governs the bracket-selection reads ONLY.

PHASE_HEADING_PREFIX_SRC is left byte-identical: PR-1 shipped it, nothing
consumes it, and it is superseded rather than redefined.

* feat(#2761): roadmap.cts selects its heading grammar from the convention

Six matchers build their intro through the gated selector, and
cmdRoadmapAnalyze / cmdRoadmapGetPhase / getRoadmapPhaseWithFallback each
resolve the convention ONCE per command and thread it down.

Three sites take the any-bracket baseline (they already tolerated
`[anything] Phase N`); three take label-only (they spelled a bare `Phase\s+`).
Handing the wider grammar to a label-only site retro-grants tolerance it never
had — and not only by adding matches: on a legacy repo an unchecked
`- [ ] **[v1.0] Phase 05: Thing**` bullet would start SUPPRESSING the W006 that
fires today.

Sentinel handling under bracket ADDS a rule rather than replacing one: a
bracketed heading is a sentinel when its bracket milestone is reserved
(`### [GSD.999] 01:`) OR when its token is, so the engine-wide 0/999 backlog
convention keeps applying to `### [GSD.02] 999:`. Replacing the token rule let a
mid-migration ROADMAP — bracket headings plus a legacy backlog block, exactly
the content this epic targets — add entries to the progress denominator. The
captured id is folded before the identity test, so a lowercase
`### [gsd.999] 07:` is excluded too.

The DIRECTORY read is threaded too. `cmdRoadmapAnalyze` resolves the convention
once and hands it to all four of its heading/checklist patterns, but the single
`phaseTokenMatches` call that decides `disk_status`, `plan_count`,
`summary_count`, `has_context` and `has_research` was left two-argument — so
every canonical `{CODE}.{MM}-{PP}-slug` directory read as `no_directory` with
zero counts, on the PR's own headline verb, while the SAME build resolved those
same directories correctly in three other places on the same repo (W006/W007 via
phaseTokenFromDir, `state json` via the milestone filter, and the W021
milestone-complete read through this very helper's three-argument form). It
failed ONLY for the directory shape the convention exists to name: a
mid-migration bracket repo carrying legacy `01-one` dirs resolved fine, which is
why nothing caught it. Measured, bracket vs its flat-legacy twin:
`[["01","no_directory",0,0],["02","no_directory",0,0]]` against
`[["01","complete",1,1],["02","planned",1,0]]`.

The oracle is the twin, computed in the same test run, plus exact literals —
`grep disk_status tests/adr-612-*` was zero hits before this, so neither the fix
nor a future regression had any gate at all.

Disclosed: a ROADMAP written in bracket form before config.json is switched
reads as empty rather than mis-counted. Silent invisibility during the migration
window is the deliberate trade against claiming phases on projects that never
opted in.

* feat(#2761): validate.cts selects its grammar; gated directory recognition

The W006/W007 feeders take the resolved convention as a threaded parameter.
These sites carry the letter-tolerant `[\w][\w.-]*` capture, which makes them
where an ungated widening does the most damage: `### [RFC.2119] 5:` enters
roadmapPhases as a phantom and becomes a W007 "in ROADMAP.md but no directory on
disk" on a project that never opted in.

buildRoadmapPhaseVariants also surfaces the tokens borne ONLY by sentinel-bracket
headings. Surfaced rather than filtered in place because roadmapPhases feeds both
a membership check and a missing-directory warning, and only the latter should
ignore an icebox item.

That set is OCCURRENCE-AWARE, and the subtlety is load-bearing: roadmapPhases is
a TOKEN set, so `[GSD.999] 01` and `[GSD.02] 01` collapse to one entry. Keying
suppression on the token alone let an icebox heading silence a REAL phase that
happens to share its number — a false negative strictly worse than the warning it
removed. A token is suppressed only when no non-sentinel heading bears it.

Directory recognition is added as gated FUNCTIONS beside the exported RegExp
constants, which stay byte-identical: the `{CODE}.{MM}-` prefix is
string-indistinguishable from the letter-prefixed-decimal family this repo
documents as ambiguous, and folding a branch in changes those constants' answers
on exactly that family. A RegExp constant has nowhere to attach a gate.

The recognizer mirrors the emit grammar and delegates the token to the canonical
owner, so recognizer and resolver agree on rejected input as well as accepted.
Both functions throw on a non-string, matching the call pattern they replace.

buildRoadmapPhaseVariants' CHECKLIST scan is capturing, like its heading twin
and like the sibling checklist scan in roadmap.cts, and for the reason that one
states: the bracket id has to ride along or the sentinel filter is blind to
`- [ ] **[GSD.999] 01: Icebox**`. Left un-capturing, the scan called every
checklist token REAL, and the occurrence-aware un-suppression loop then deleted
the icebox token the HEADING scan had correctly marked sentinel — so `validate
consistency` warned that a bracket ICEBOX phase had no directory, in the HOUSE
ROADMAP shape where an icebox appears as both a bold bullet and a detail
heading. `validate health` stayed silent on that same repo, so the two verbs
disagreed — which is the disagreement `sentinelPhases` exists to close.

Both directions are pinned, because the failure mode of a careless fix here is
the opposite one: a real phase sharing a sentinel's token must still warn. It
does, in all four shapes that attack it (sentinel heading + real bullet,
lowercase sentinel, sentinel after the real heading, colon-less bullet).

* fix(#2761): count bracket headings, and retire them, in both derivations

Both `total_phases` derivations select their grammar from the resolved
convention, in one commit — cmdStateSync already carries the comment that it
mirrors buildStateFrontmatter "so both report consistent percents (#3242 Bug B)",
so teaching one and not the other ships that divergence.

The #1514 retirement filter widens WITH the counter it protects. The canonical
gesture strikes the checklist BULLET and leaves the detail heading intact, so a
bracket-form retirement went undetected and the phase stayed in the denominator
forever. That is half a fix alone: the retired key is compared against
phaseKeyFromDir, which called extractPhaseToken with no convention. Both halves
land here.

Under bracket the sentinel token rule composes as the full engine set {0, 999},
so this counter agrees with `roadmap analyze`, which has always excluded both —
otherwise the two derivations report different numbers for one ROADMAP and the
changeset's "excluded from every count" is false as written. The LEGACY path
keeps its pre-existing 999-only rule: widening it there would move legacy totals,
so the two stay split off the bracket path exactly as they are today.

The sync-side assertion reads the PERCENT sync writes into the STATE.md body, not
the frontmatter total_phases. Sync's own counter never reaches that field — the
read derivation writes it — so asserting the frontmatter after a sync measures the
read path twice and lets a mutation to the write-path guard survive.

* feat(#2761): verify.cts bracket-coherence W021 + selected milestone-complete read

The shipped milestone-prefixed W021 gate keeps its ROOT-only config read,
verbatim base semantics. Federating it silently moved a legacy convention's
answer in BOTH directions on workstream repos — a W021 that fires at base
vanishing, and one that is silent at base firing. resolvePhaseIdConvention
governs the new bracket-selection reads only.

B6, the milestone-complete check, keeps its ungated POSTURE (bug-557 pins it
with an empty config) but selects its grammar from the convention. Inferring
'bracket' from the shape of a matched bracket ran a repo-failing check against a
legacy ROADMAP that merely contained `### [RFC.2119] 5:`. Directory resolution
widens with the heading read, so a bracket repo whose phases are on disk stays
silent, and a bracket sentinel is not reported as unstarted.

checkBracketCoherence is advisory and gated. Anchored to tokenizeHeadings so
fenced examples cannot warn and heading level is structural. Its scope rules each
close a way it silently did nothing or fired wrongly: only a genuine MILESTONE
heading opens or closes a section (a `### Notes` used to reset scope and disable
both sub-checks); a legacy `## v3.0` DOES close it; an M-NN or letter-suffixed
phase heading raises missing-bracket and CONTINUES; a bare `#### 2026:` is not a
phase; the full h2-h6 range is processed. Its section recognizer shares the one
milestone width, so an unpadded `### [GSD.3] 05:` can no longer be a phase to the
id grammar and a section to the section grammar at once, silently re-scoping
every warning after it.

validate consistency suppresses bracket sentinels in its missing-directory
warning — the two verbs disagreed, health suppressing via notStartedPhases while
consistency did not. The legacy reading is untouched, including its pre-existing
wart that `### Phase 999:` still warns there.

* fix(#2761): scope the milestone by its bracket; select the disk-side filter

Two roadmap-parser reads, both of which made a bracket project's totals track
the disk instead of the ROADMAP.

The ADR pins the bracket milestone heading as `## [GSD.02] Foundation` — a name,
no version — but scoping matched STATE's `milestone: v2.0` STRING against a
heading, so the canonical form matched nothing and total_phases fell back to the
directory count. The rule was re-derived in THREE places: extractCurrentMilestone
plus two `milestoneBounded` guards; fixing one left the others falling back
regardless, so they are now one gated helper. It matches the CANONICAL padded
spelling only — accepting `0*N` bounded a milestone whose phases were invisible,
which un-suppressed a progress percent computed off an unscoped disk count.

getMilestonePhaseFilter's heading scan becomes the 14th selected read. On a
bracket ROADMAP it collected nothing, so the filter degraded to pass-all and
buildStateFrontmatter counted every other milestone's directories — making the
bracket convention strictly worse than the M-NN one it supersedes on the property
that matters most: totals must track the ROADMAP, not the disk.

The DIRECTORY side of that same filter is selected with it. Teaching only the
heading scan was half a fix and a worse one: `milestonePhaseNums` became
non-empty, so the pass-all degrade stopped firing, but no bracket directory could
satisfy the three legacy dir checks (numericRe fails on `GSD.02-05-five`, the
custom-id match captures the project code `GSD`, and stripProjectCodePrefix does
not strip a dotted prefix). Every bracket directory was rejected, and
completed_phases / total_plans / completed_plans / percent all collapsed to 0
while `state sync` went on writing a percent off the unfiltered disk — `state
json` reporting 0% on the same repo, in the same second, that STATE.md's body
called 67%. That is the #3242 Bug B divergence this PR exists to avoid, and
total_phases could not show it: `Math.max(phaseDirs.length, roadmapPhaseCount)`
floors it at the ROADMAP count no matter how many directories are rejected.

The dir side matches on the milestone-QUALIFIED id, delegated to the owner's
gated `phaseTokenMatches(dir, id, 'bracket')`, not on the bare token: READING-B
puts the milestone in the bracket, so `GSD.01-01-old-one` and `GSD.02-01-one`
share the token `01` and only the qualified key separates them. The qualified ids
are kept in their own set — a hyphen in `milestonePhaseNums` would flip
`roadmapUsesHyphenedIds` and silently move the LEGACY dir path on a bracket repo
— and the branch is ADDITIVE: on a miss it falls through to the three legacy
checks, so a bracket project carrying legacy-shaped directories reads unchanged.

Both are resolved lazily and gated, so the legacy path pays neither a config read
nor a second scan and cannot change answer. The scoping call is also GUARDED:
resolvePhaseIdConvention reaches planningDir, which throws a plain Error for a
GSD_PROJECT/GSD_WORKSTREAM segment carrying `/`, `\` or `..`. At base the only
planningDir call in extractCurrentMilestone sits inside the STATE-read try, so
the function returned normally on such an environment; an unguarded one here let
that escape and broke the never-throws invariant that getRoadmapPhaseInternal and
getMilestoneInfo three hundred lines below carry #2245 / ADR-227 notes about.
Unreachable through the CLI — GSD_WORKSTREAM is rejected up front by the
workstream-name policy and GSD_PROJECT throws identically at base — but reachable
by any in-process embedder, which is precisely who that invariant is for. The
filter's own resolve call was already inside its try and is unaffected.

The milestone-qualified key is formed only for a token that is itself a bracket
phase token. `${bracketId}-${token}` is a string SPLICE, so a mid-migration
heading carrying an M-NN label — `### [GSD.02] Phase 02-01:` — spliced to
`GSD.02-02-01`, which the qualified-key grammar reads as milestone 02 / phase 02:
the `-01` truncated, both such headings collapsing to one key, and the heading
claiming `GSD.02-02-two`, the directory it does NOT name, while rejecting
`GSD.02-01-one`, the one it does. The guard drops those headings back to the
unqualified legacy path, restoring the base ACCEPTANCE VECTOR exactly — pinned
against the milestone-prefixed reading of the same ROADMAP, which is
base-identical on this shape.

Scoped precisely, because the fixture moves one number that the guard does not
touch: `total_phases` on it reads 1 at base and 2 here. That is the bracket
heading COUNT this PR exists to add, not the splice — measured identical with and
without the guard, and identical to what the canonical `### [GSD.02] 01:`
spelling does on the same fixture (both read 2 with zero directories on disk,
where base reads 0). The claim is base-equivalent ACCEPTANCE, not a
base-equivalent reading.

One consequence is stated rather than fixed: a heading whose token carries a
hyphen still puts that hyphen into milestonePhaseNums and so still flips
`roadmapUsesHyphenedIds`. Base does the same for that spelling, so preserving it
is what keeps the shape base-equivalent; excluding the token would have moved
answers versus base on malformed input. The comment at the qualified-set
declaration is corrected to claim only what is true — it keeps QUALIFIED IDS out
of that flag's input, not hyphens in general.

The oracles ship with it, and they are the five numbers, not the one: the parity
gate now asserts total_phases, completed_phases, total_plans, completed_plans AND
percent, on both derivations, on two fixture shapes (one milestone; two
milestones with stale prior-milestone directories on disk). The oracle is the
flat-legacy twin, built in the same test run and compared number for number,
plus exact literals so a shared wrong answer cannot pass.

The oracle SUBSTITUTION is itself pinned. The M-NN spelling of these shapes could
not serve, because buildStateFrontmatter's #2445 de-dup key captures only a
directory's leading integer and collapses `02-01-one` / `02-02-two` /
`02-03-three` to one — measured [3,0,1,0,0] against the flat-legacy twin's
[3,2,3,2,67], identically at base and before this fix, and structurally
unreachable from the bracket key space. That reasoning is only sound while it
stays true, so a characterization test holds the M-NN reading down on the two
numbers that do not depend on which directory wins the mtime race. Widen the
de-dup key and it fails, instead of quietly invalidating the changeset's
disclosure.

Also adds the call-site pin. The structural table pins transcription against the
selector; it cannot see a call site whose BASELINE ARGUMENT is wrong. Flipping
verify.cts's milestone-complete site to the wider baseline grants a
fires-on-every-repo check tolerance it has never had, and every behavioural test
still passed. The pin reads the shipped sources and asserts the mode at each of
the 14 sites, count-exact.

* test(#2761): pin the bracket read surfaces in the parity gate

This gate exists because #2043 fixed one bug across five hand-edited copies of a
rule and #2232 was the residual that survived, because a later reader could not
tell the copies were one rule. PR-2 adds two consumers, so they belong here.

Surface 7 — the heading read and the directory read must agree about WHICH phase
a `MM-<seg>` pair names, across the shared width corpus, and the bracket and
legacy spellings of one heading must yield the same token.

Surface 8 — the two bracket directory readers, in BOTH directions. Agreement on
ACCEPTED input was already pinned; agreement on REJECTED input is where they
actually diverged.

* chore(#2761): changeset

Disclosures for the PR body (deliberate, not defects):

- phase_id_convention is not a CONFIG_DEFAULTS key, so loadConfig drops it and
  cannot serve as the convention resolver however the file is federated. This PR
  ships its own workstream->root resolver; adding the key and its value enum is
  later-slice work.
- Convention matching is strictly === 'bracket'. A misspelled value reads as
  not-configured and the project keeps legacy behaviour silently.
- An UNPADDED bracket milestone (`[GSD.2]`) is malformed: it scopes nothing,
  bounds nothing, sections nothing, and is not a phase id. W005 on its
  directories is the surfacing signal.
- WIDTH UNIFICATION MOVED FOUR MERGED PR-1 EXPORT ANSWERS on non-canonical
  inputs, none of which toDir can emit and none of which had a bracket caller at
  base:
    isSentinelPhaseId('GSD.0-01',    'bracket')  true  -> false
    isSentinelPhaseId('GSD.0999-01', 'bracket')  true  -> false
    getMilestoneFromPhaseId('GSD.2-01',   'bracket')  'v2.0' -> null
    getMilestoneFromPhaseId('GSD.002-01', 'bracket')  'v2.0' -> null
  The canonical pad2 sentinel spelling `[GSD.00]` still tests true.
- FLAG TO MAINTAINER: docs/adr/612:132 reads "Sentinel behavior (0.x / 999.x ->
  milestone null) is preserved". After the unification that holds for the
  canonical `00` spelling only, not for a bare `[GSD.0]`. ADR wording is yours;
  flagging the tension rather than editing it.
- The bracket sentinel rule COMPOSES with the legacy one — a bracketed heading is
  a sentinel when its bracket milestone OR its token is reserved. Under bracket
  the state-side token rule is the full {0, 999} set so both derivations agree;
  the LEGACY path keeps its pre-existing 999-only rule, unchanged.
- validate consistency's legacy reading is untouched, including the pre-existing
  wart that `### Phase 999:` warns there while validate health suppresses it.
- find-phase still cannot resolve a bracket phase directory. phase-locator.cts is
  outside this PR's module set. Sibling PR #2559's matchPhaseDirs calls
  phaseTokenMatches without a convention, so whichever slice lands second must
  thread it through.
- Four of the five bracket readers scan raw ROADMAP content, so a bracket heading
  inside a fenced code block is read as a phase. Pre-existing for the legacy
  spelling; parity, not a new class.
- roadmapPhaseLookupSources gained no bracket source: nothing emits a
  milestone-qualified query into it yet.
- roadmap validate remains a separate, unfederated convention reader.
  Pre-existing and base-identical, but two verbs can disagree about the active
  convention on one project.
- _diskScanCache keys on cwd while the values it caches are now
  convention-dependent. Not reproducible through the CLI; pre-existing for the
  workstream dimension, widened here. Stated as inconclusive.
- A ROADMAP written in bracket form before config.json is switched reads as empty
  rather than mis-counted — the deliberate migration-window trade.
- THE READ AND WRITE PERCENTS STILL DIVERGE ON A MULTI-MILESTONE REPO, and that
  divergence is MIRRORED under bracket rather than closed. buildStateFrontmatter
  applies the milestone filter; cmdStateSync does its own fs.readdirSync and never
  calls it, so on a repo carrying prior-milestone directories the read path
  reports the SCOPED percent and the sync body reports the WHOLE-DISK one.
  Measured on the true base build (d04592de), flat-legacy spelling, 3 in-scope
  phases with 1 complete plus 2 stale prior-milestone dirs: `state json`
  [3,1,3,1,33], sync body 60%. The bracket twin of that repo now reads the same
  two numbers — 33 and 60. Scoping the sync counter would move every legacy
  repo's percent, which a bracket read-path PR must not do. The gate pins both
  sides, so the mirror cannot silently become a one-sided fix.
- THE PARITY ORACLE IS THE FLAT-LEGACY TWIN, NOT THE M-NN ONE, and that is a
  measurement finding rather than a preference. buildStateFrontmatter's #2445
  de-dup key captures only a directory's LEADING integer, so the M-NN dirs
  `02-01-one` / `02-02-two` / `02-03-three` all key to `2` and two of the three
  are dropped before they are ever counted: base reads [3,0,1,0,0] where the
  flat-legacy twin of the same repo reads [3,2,3,2,67]. Present identically at
  base and at HEAD, untouched here, and structurally unreachable from the bracket
  key space — `GSD.02-01-one` does not match that pattern at all, so every bracket
  directory keys to its own name. The source line already carries a
  `phase-id-owner:` sanction recording the divergence. Mirroring it under bracket
  would mean manufacturing a collision that cannot occur, so the gate compares
  against the flat-legacy spelling, which is uncontaminated. This paragraph is
  itself pinned: a characterization test holds the M-NN reading on the two
  numbers that do not depend on which directory wins the mtime race, so widening
  the de-dup key in a later slice fails the suite rather than silently making
  this disclosure false.
- THE `phaseTokenMatches` CALL-SITE CENSUS, stated so the remaining gaps are
  auditable rather than implied. 13 call sites outside the owner (phase-id.cts).
  THREE are three-argument: verify.cts:2229 (the W021 milestone-complete read,
  already was), roadmap.cts:436 (`roadmap analyze`'s directory lookup, threaded
  by this PR) and roadmap-parser.cts:792 (the disk-side milestone filter, added
  by this PR). The other TEN are two-argument and stay that way — phase.cts ×5
  (220, 277, 444, 585, 1547), phase-locator.cts:62, smart-entry.cts:243,
  init.cts:1414, milestone.cts:551 and verify.cts:2467. All ten are untouched by
  this PR and base-identical.
  One of them sits in a file this PR DOES edit, so it is named rather than left
  to a reader's grep: verify.cts:2467, `verify schema-drift <phase>`. Measured on
  a bracket repo across base / pre-fix branch / this HEAD, all three agree on all
  three argument forms — `verify schema-drift GSD.02-01` and `… 01` both report
  "Phase directory not found" on every build, and `… GSD.02-01-one` resolves on
  every build through the exact-directory-name fallback. So the user-visible
  shape of what stays broken is: a bracket phase is addressable there by full
  directory name only, exactly as at base. Threading the convention into a
  function this PR never touched, in the last round before ship, is the wrong
  trade; it is where the same one-argument fix goes next, alongside
  milestone.cts:551 and init.cts:1414.
- A BRACKET HEADING WHOSE TOKEN CARRIES A HYPHEN (`### [GSD.02] Phase 02-01:`,
  a mid-migration spelling) forms NO milestone-qualified key, and therefore
  scopes through the unqualified legacy path — base-equivalent ACCEPTANCE, which
  is the claim, and not a base-equivalent reading: `total_phases` on that shape
  moves 1 -> 2 for the same reason it moves on the canonical `### [GSD.02] 01:`
  spelling, because counting bracket headings is what this PR does. Such a token
  still flips `roadmapUsesHyphenedIds`, as it also does at base. The comment at
  the qualified-set declaration now claims only that narrower, true thing.

The `pr:` field carries the sub-issue number as a placeholder — it must be
updated to the real PR number when the PR is opened.

* chore(#2761): point the changeset at PR #2867

* test(#2761): fast-check properties for the convention-selection layer

CONTRIBUTING.md mandates a generative property test for parser/bijective-contract
changes; PR-2 shipped six example-based files and none. This adds the missing
layer, scoped to what PR-2 actually contracts — WHICH pattern each reader
compiles, decided by the resolved `phase_id_convention` — rather than restating
PR-1's grammar round-trip properties, which already live in
tests/adr-612-bracket-grammar.test.cjs.

Four properties: P1 an opted-in repo reads the ADR-canonical label-less bracket
heading/dir and a non-opted-in repo is byte-blind to the identical input; P2
every non-bracket convention agrees with the hand-transcribed BASE source over
generated content, including bracket-DOTTED legacy prose (`[RFC.2119] 5:`) that
must never be claimed as a phase; P3 nine per-field mutations are rejected and
the one case variation folds instead; P4 both sides of a phase comparison derive
the same key under the same convention.

Generators template every input from raw primitives — nothing is seeded through
renderPhaseId/toDir, the p2() tautology that made #2258 round 1's property test
structurally unable to find B1. Domain reaches past 99 into the 3+-digit branch
(round 2's numArb-capped-at-99 miss), forces sub-phases in at weight, and pins
both sentinel milestones.

Falsified against the COMPILED lib, not the source: five deliberate mutants
(gate never fires; gate always fires; milestone width widened to \d+; the #612
convention forwarding dropped from phaseKeyFromDir; extractPhaseToken's bracket
branch ungated) each fail the specific property that should catch them —
16/2, 16/2, 15/3, 17/1, 17/1 pass/fail — and the lib restores byte-identical.

An earlier draft of P2 held vacuously: its base regex omitted the markdown
furniture the selected one carried, so every realistic `### Phase NN:` line
matched neither side. The gate-always-fires mutant did not kill it. Both are now
compiled through one function, and that mutant kills P2.

* test(#2761): adversarial malformed bracket tokens across the tolerant readers

The existing boundary coverage stopped at shapes the emit grammar rejects
(unpadded `[GSD.3]`, wrong-case, `12A`). It never exercised a STRUCTURALLY
broken token — a non-numeric milestone, a bracket that never closes, a bracket
nested in another — which is the input a tolerant reader is most likely to
half-read, and the one the PR's own regex commentary is explicit about.

read-tolerance (roadmap heading scan + validate's dir and variant builders):
ten malformed headings, each asserted to be read as a phase by NO convention and
to give the opted-in repo the same answer as the legacy one; the corpus driven
through `roadmap analyze` end to end; malformed DIRECTORY names asserted
unrecognized and non-throwing on all four conventions; and the two variant
builders asserted to agree, since a widening that reaches only one splits
`validate consistency` from `validate health` (the #3242 Bug B shape).

coherence (verify.cts W021): the same six broken shapes asserted to raise no
W021 of their own AND not to re-scope the W021 that follows them — the G2
failure mode reached from a different shape, where a heading that is not a phase
but IS read as a section silently moves later warnings onto the wrong milestone.

Both files gain a pathological-input time bound. Nested quantifiers over a long
unclosed bracket are the classic ReDoS shape and two commits on next (#2828,
#2944) were CodeQL-flagged for exactly that, so the bound is asserted rather
than argued from reading the pattern. The probes themselves parse no regex.

* docs(#2761): document "bracket" as a phase_id_convention value

The row listed only `"milestone-prefixed"` and `null`, so after two shipped
slices (#2258 grammar, this PR's read path) the convention had no documented
enum value. CONFIGURATION.md is also a top-10 historical co-changer of both
src/verify.cts and src/state.cts and was absent from this PR.

The row states the boundary rather than the ambition: `"bracket"` changes the
READ path only, there is no migrator and no emit yet, and a project on any other
value compiles the patterns it compiled before. That keeps the docs honest for
the two releases before PR-3 and PR-4 land, instead of describing a convention a
user cannot yet migrate to.

* chore(#2761): retype the changeset Added, drop the docs-exempt marker

`Fixed` was wrong by CONTRIBUTING.md's own definition — a fix restores
documented behavior, and bracket read tolerance is the second slice of a
capability that did not exist before #2258. The type also carried a
`docs-exempt` marker, and `Fixed`/`Security` are exempt from the docs-required
lint, so the typing had the effect of routing around a gate this change should
pass. It now passes it: `lint-docs-required` returns ok_docs_updated on the
CONFIGURATION.md row added in the previous commit.

Body gains one sentence pointing at that row and restating that `"bracket"` is a
read-path opt-in until the migrator and write path land.

* test(#2761): pin the version-less bracket milestone scoping gap; narrow the claim

The changeset asserted that milestone scoping "recognises the ADR-canonical
`## [GSD.02] Foundation` heading and applies to the phase DIRECTORIES too." A
CLI probe on that exact heading form falsifies the second half: with no `vN.N`
in the milestone heading the directory side does not scope, and directories from
BOTH the prior and the later milestone are admitted. Measured 4 dirs counted
where the milestone declares 2.

Every bracket fixture in the suite writes `## [GSD.02] v2.0: …`, so nothing
covered the form the ADR actually specifies — and the state.cts doc comment
calls that version-less form canonical.

Mechanism, in extractCurrentMilestone: the bracket scope branch selects the
right currentSection, but `preambleCutoff` keys off a pattern requiring a
version or status emoji, so a version-less roadmap falls back to the current
milestone's own offset and every PRIOR milestone lands in the preamble — whose
phase-stripping regex only strips `Phase N:`-labelled headings, so bracket phase
headings survive it. Independently, `computeSectionEnd` accepts a boundary only
on a version/emoji heading, so the section runs to EOF and every LATER milestone
is swept in. Two sites, bidirectional.

Not fixed here: it changes milestone scoping, which is shared with the legacy
path. Five characterization tests pin today's reading plus a versioned CONTROL
proving the version string is the only difference, and the changeset sentence is
narrowed to what the code does. The DEFECT assertions are written to be
INVERTED by the fix, not deleted — that inversion is its regression proof.

* docs(#2761): re-anchor the branch's own cross-file line citations after the rebase

Three of this branch's code comments cite sibling call sites by line number, and
the rebase onto 178ec000 moved two of the three targets:

  roadmap-parser.cts  validate.cts:210 -> :218   (const g = capturing ? 1 : 0)
                      state.cts:1715   -> :1752  (const bg = … 'bracket' ? 1 : 0)
  roadmap.cts         verify.cts:2229  -> :2355  (phaseTokenMatches 3-arg form)

`state.cts:1715` had drifted 37 lines and now lands on the retirement skip, not
the capture-offset idiom the sentence is about — the citation read as evidence
for a claim the cited line does not support.

planning-workspace.cts's `config-loader.cts:618/:649` was checked and is still
correct; left alone.

Comment-only. Build, drift guard and the bracket suites re-run unchanged.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#2761): scope the version-less bracket milestone heading too (B1)

computeSectionEnd and the preambleCutoff scan in extractCurrentMilestone
(roadmap-parser.cts) only recognized a milestone boundary heading that
carried a vN.N token or a status emoji. The ADR-canonical bracket
heading (## [GSD.02] Foundation) carries neither, so on that shape
computeSectionEnd fell through to content.length (sweeping every LATER
milestone into scope) and preambleCutoff fell back to the current
milestone's own offset (leaking every PRIOR milestone's bracket phases
into the preamble, whose Phase-N: strip regex never matches them).

Under the bracket scope branch, both sites now also accept a
`#{1,2}\s+\[CODE.MM\]` boundary, built from phase-id.cts's BRACKET_ID_SRC
(single owner of the bracket-id grammar) rather than a re-typed literal.
`#{1,2}` is the deliberate discriminator: a bracket PHASE heading is
level 3 and shares the same `[CODE.MM]` prefix, so a `#{1,3}` boundary
would swallow it too. Reachable only when bracketScopeConvention ===
'bracket' was already resolved (i.e. the bracket scope branch actually
fired), so version-bearing/emoji headings and non-bracket conventions
take the exact pre-existing code path byte-identically — confirmed by
the full adr-612 suite staying green.

Inverts the four DEFECT assertions in the
"#612 PR-2 CHARACTERIZATION: a version-less bracket milestone does not
scope" describe block (tests/adr-612-bracket-phase-counting.test.cjs)
into their regression-proof form, per the block's own doc comment, and
reframes the describe title/comments accordingly. Corrects the
.changeset/2761-bracket-read-tolerance.md fragment, which described the
directory-side version-less gap as an open, un-closed bound.

* fix(#2761): thread sentinelPhases into validate health's W006 loop (B2)

cmdValidateHealth's W006 loop (src/verify.cts) destructured only
roadmapPhases from buildRoadmapPhaseVariants, not sentinelPhases —
unlike cmdValidateConsistency, which already skips sentinelPhases with
the identical guard a few hundred lines up. A heading-only bracket
icebox/pre-milestone entry ([GSD.999] / [GSD.00]) therefore gained a
false W006 "no directory on disk" from validate health while validate
consistency correctly stayed silent on the very same ROADMAP — the two
validators contradicting each other.

Threads sentinelPhases through and skips it before the existsOnDisk
check, mirroring the consistency guard exactly. Gated the same way
sentinelPhases already is (empty unless phase_id_convention is
'bracket'), so a legacy repo's W006 reading — including its own
pre-existing wart where a legacy `### Phase 999:` still warns on both
verbs — is untouched; confirmed by the existing "INHERITED WART,
unchanged" test staying green.

Adds the paired-agreement regression test (#612 PR-2 B2 describe block
in tests/adr-612-bracket-read-tolerance.test.cjs): a sentinel-only
bracket roadmap must produce no missing-directory warning from EITHER
validator, plus a CONTROL proving a real phase with no directory still
warns on both. Confirmed red (health false-W006) against the pre-fix
code before applying the fix.

Corrects the .changeset/2761-bracket-read-tolerance.md fragment, which
described the asymmetry as already closed and in the wrong direction
(it credited validate health with already staying silent, when health
was the one falsely warning).

* test(#2761): pin mixed-shape preamble cutoff and boundary heading levels

Closes two self-flagged coverage gaps in the B1 fix (commit 08d5b0c4)
ahead of adversarial review. No src change — all three new tests are
green against the code as committed.

1. earliest-of-either preambleCutoff comparison: only exercised where
   the version/emoji match and the bracket match happen to land on the
   same heading. Adds the mid-migration mixed shape (version-bearing
   PRIOR + version-less CURRENT) and asserts scoping outcomes (accepts
   booleans + total_phases), not internals.

2. `h.level <= 2` conjunct in computeSectionEnd: provably redundant
   whenever the selected milestone heading is level 2 (every existing
   fixture), since `h.level > level` alone already implies it there —
   a mutant deleting the conjunct would have survived every prior test
   in this file. Adds a level-3 CURRENT-heading fixture (with a real
   PRIOR milestone so the preamble side-channel can't independently
   rescue the truncated phases) that makes the conjunct's deletion
   test-visible, confirmed by hand-mutating a throwaway copy of the
   compiled output (never touching tracked src or the real build) and
   observing the assertion flip. Also pins a level-1 companion case
   (#{1,2} tolerance, not just level 2).

NOT included here: the other mixed-shape direction (version-less PRIOR
+ version-bearing CURRENT) turned out to be a genuine, currently-unfixed
gap — reported separately rather than silently patched or weakened, per
instruction not to touch src while a probe run is in flight.

* fix(#2761): engage bracket boundaries when the current milestone heading is version-bearing (B3, self-caught)

Found during round-2 self-verification of B1 (commit 08d5b0c4), while
closing the mixed-heading-shape coverage gaps flagged in my own review
notes. The B1 fix resolved `bracketScopeConvention` only inside the
`if (headingMatches.length === 0)` gate that also drives SELECTION's
own bracket fallback (which heading counts as "current"). That gate is
correct for selection, but `bracketScopeConvention` also feeds
computeSectionEnd's and preambleCutoff's boundary detection further
down — which accidentally inherited selection's gate instead of having
its own.

Trigger shape: the CURRENT milestone heading is itself version-bearing
(`## [GSD.02] v2.0: Current Milestone`), so the primary version-string
match succeeds immediately — headingMatches.length !== 0 from the very
first check — and the entire bracket-resolution branch was skipped. A
sibling milestone (PRIOR or LATER) that is version-less then got
neither the version/emoji boundary rule (it has none) nor the bracket
boundary rule (never resolved), reproducing the original #612 defect
(total_phases falling back to the whole-disk count) through a
structural shape B1's own fixtures never exercised — every one of them
is uniformly version-bearing or uniformly version-less across all
three milestones, never mixed with CURRENT specifically being the
version-bearing one.

Fix: resolve `bracketScopeConvention` unconditionally, decoupled from
`headingMatches.length`. SELECTION is deliberately left untouched — the
`if (headingMatches.length === 0 && bracketScopeConvention === 'bracket')`
fallback that picks which heading is "current" keeps its original gate
byte-for-byte (confirmed by diff: that line is unmodified). Only the
convention *resolution* moved out from behind it, so boundary detection
can consult it regardless of which branch selected the heading. The
extra `resolvePhaseIdConvention` call this now costs on every
invocation (previously paid only when the version match found nothing)
is the accepted cost: a non-bracket repo still resolves to something
other than 'bracket' (or null on a poisoned env, caught exactly as
before), so `bracketMilestoneHeadingRe` stays null and every downstream
branch is byte-identical to today — confirmed by the full adr-612 +
roadmap-parser + state + verify + health-validation suite staying green
(1260/1260) and the all-version-bearing/legacy fixtures showing no
behavior change.

TDD: tests/adr-612-bracket-phase-counting.test.cjs describe block
"#612 PR-2 B3: bracket boundaries engage even when CURRENT is
version-bearing but a sibling is not" — 4 tests, confirmed red against
pre-fix code (leak-in booleans true/true, total_phases 4) before this
change, green after.

* fix(#2761): reject same-milestone continuation headings as boundaries (B1)

Gate-2 adversarial review Blocker 1: the B1/B3 boundary fired on ANY
as the one currently selected — a version-less checklist/detail split
(`## [GSD.02] Foundation (Phase Details)`, or an ad-hoc continuation
heading) truncated the current milestone's own section instead of
being recognised as a continuation of it. The `(Phase Details)`
re-append only searches VERSION-STRING matches, so a version-less
continuation heading was cut out and never re-appended — a confidently
wrong, non-degraded phase count for a still-incomplete milestone
(repro8 case 1: 1/1/100 instead of 2/1/50; repro5: same, on a fully
version-less roadmap with no sibling milestones at all).

Introduces one shared helper, isBracketMilestoneBoundary(headingText,
level, selectedBracketId), used by both computeSectionEnd and the
preambleCutoff bracket scan, replacing the ungated `h.level <= 2 &&
bracketMilestoneHeadingRe.test(...)` inline check. `selectedBracketId`
(case-folded via phase-id.cts's foldBracketId, matching the branch's
own fold-before-identity convention) is derived from `selected[0]`,
which is the full matched heading line on BOTH selection paths
(version-string and bracket-fallback), so one extraction covers both.

Level cap stays at `level > 2` for now (temporary — ADR-612's content
discriminator replaces it in the next commit); same-milestone rejection
is the change this commit is scoped to.

DEVIATION from the reviewed plan, caught empirically: applying the
same-milestone rejection at the preambleCutoff site (as literally
specified) regressed an existing pin ("boundary heading level: a
level-1 CURRENT milestone heading also scopes correctly") and a
fenced-heading case (repro10 A3) — because preambleCutoff's job is
"where does the earliest milestone-shaped heading sit, scanning from
the TOP of the document," and the selected heading's own occurrence is
always a correct answer to that question regardless of same-id-ness;
rejecting it let the earliest-of-either comparison fall through to a
stray LATER heading instead. `selectedBracketId` is threaded through as
`null` at the preambleCutoff call site for this reason — bracket-shaped
(and, from the next commit, phase-tail) discrimination still applies
uniformly at both sites; only the same-milestone component is
call-site-specific, since it encodes a "keep scanning past this
heading" instruction with no counterpart in a top-of-document search.

Tests: new describe block "#612 PR-2 B1 round-2: a same-milestone
continuation heading is not a boundary" — RED-turned-GREEN fixtures for
repro8 case 1 and repro5, plus PINs for repro8 case 3 (trailing
different-id icebox still terminates) and repro10 A1 (all-version-
bearing + icebox + Phase Details stays exactly 2/1/50 — no double-count
from the same-milestone exclusion interacting with the pre-existing
detailsMatch re-append). syncedTotal()/syncedPercent() assertions
omitted from the repro10 A1 pin: that fixture carries dirs outside the
current milestone, which exposes the SEPARATE Major 1 defect
(cmdStateSync's body percent from an unfiltered disk scan) — asserted
once Major 1 is fixed, not here.

* fix(#2761): bracket boundary discriminates by content, not heading level (B2)

Gate-2 adversarial review Blocker 2: three sites disagreed about which
heading levels are a bracket milestone. The selector
(roadmap-parser.cts's bracket-fallback SELECTION branch,
`^#{1,3}\s+\[CODE.MM\]`) and `isMilestoneBounded` (state.cts) both
admit level 1-3, but isBracketMilestoneBoundary's level cap only
admitted level 1-2 (`h.level <= 2`, from the B1 commit). A `###`-level
bracket milestone heading was therefore SELECTED and BOUNDED but never
TERMINATED: computeSectionEnd ran with level=3, a level-3 SIBLING
milestone survived the pre-existing `h.level > level` (not-deeper)
filter, failed the version/emoji test (version-less), then failed
`h.level <= 2` — falling through to `return content.length` and
sweeping the sibling milestone's own phases into the current one.
Reproduces trek-e's original #612 defect verbatim ("a safe degrade
became a confidently-wrong persisted number") on a heading level the
selector and bounding predicate both already admit (repro2 case C:
4/75% instead of 2/100%; mechanism confirmed directly via repro7 —
extractCurrentMilestone returned the whole 214-byte document).

ADR-612 Decision 1 (docs/adr/612-bracket-phase-id-convention.md:56)
specifies the discriminator as CONTENT, not level: "a phase heading is
a bracket followed by a digit-then-colon ([GSD.02] 05:); a milestone
heading is a bracket followed by a name." Replaces the `level > 2`
rejection with BRACKET_PHASE_TAIL_RE — built by interpolating
phase-id.cts's single-owner phaseHeadingPrefixSrcFor(ANY_BRACKET,
'bracket', false) plus the digit + optional-tag + colon tail every
phase-heading counter in this file already spells, not a re-typed
grammar — and widens the level check to a depth-sanity cap of 3
(mirroring the selector's own `#{1,3}` ceiling; NOT itself a
phase/milestone discriminator). Covers the dotted sub-phase heading
form (`[GSD.02] 05.03:`) via the same `[\w][\w.-]*` token, pinned by a
new fixture — the shape where a regex slip in the tail grammar would
hide.

preambleCutoff's own raw-scan regex is widened from `^(#{1,2})` to
`^(#{1,3})` in lockstep: the outer pattern's level ceiling must track
the helper's cap, or a level-3 PRIOR milestone heading is invisible to
that scan and its own phase heading leaks into the preamble
un-stripped (a real double-count this widening closes, verified
against repro2 case C directly).

The existing "boundary heading level: a level-3 CURRENT milestone
heading still scopes correctly" pin (3e562f12) now passes via a
DIFFERENT mechanism than before — its own neighbours are version-
bearing, so it previously passed via the version/emoji rule (the level
cap was never actually exercised by that fixture, per the round-2
review's own finding); with the content discriminator, the SAME
fixture's level-3 phase headings are now correctly excluded because
they are phase-tail-shaped, not because they are too deep. A
deliberate mechanism change, confirmed by re-running that test green
after this commit.

Also updates the "every selector call site declares the right
baseline" governance pin (adr-612-bracket-heading-selection.test.cjs):
BRACKET_PHASE_TAIL_RE is a new, legitimate ANY_BRACKET call site in
roadmap-parser.cts (always passing the literal 'bracket' convention,
since its only caller is already gated on bracketBoundaryActive) —
EXPECTED count bumped 1->2, with a matching BASE_SITES transcription
entry (identical src to every other ANY_BRACKET site, since the
function is pure).

Tests: new describe block "#612 PR-2 B2 round-2: the bracket boundary
is a CONTENT discriminator, not a level cap" — RED-turned-GREEN for
repro2 case C (exact total AND truthful percent, since
isMilestoneBounded already returns true at #{1,3}) and repro7's
mechanism, a PIN for the dotted sub-phase form, and a re-pin of repro8
case 3 (icebox) under the new mechanism.

Full suite green (907/907 across the targeted adr-612 + roadmap-parser
+ state + phase-id files); node scripts/lint-phase-id-drift.cjs clean;

* fix(#2761): fence-aware preamble cutoff on the bracket branch (Blocker 3)

Gate-2 adversarial review Blocker 3: preambleCutoff's bracket scan used
a raw content.match/matchAll — blind to fenced code blocks — while its
sibling computeSectionEnd (a few lines above it) already consumed
tokenizeHeadings(content), which strips fences. The two halves of one
boundary semantic disagreed about what a heading is.

A fenced markdown example in the preamble containing a bracket heading
(ADR-612's own docs do exactly this) was textually the earliest
`#{1,3} [CODE.MM]` match: preambleCutoff landed INSIDE the fence,
`preamble = content.slice(0, preambleCutoff)` ended with an unclosed
opener, and the unbalanced fence then blinded
getMilestonePhaseFilter's own tokenizeHeadings(scope) call — every
heading in the returned scope vanished, phaseCount degraded to 0, and
the pass-all filter admitted every directory on disk (repro11's
mechanism, confirmed directly: fence count 1/odd, tokenizeHeadings(scope)
-> only "Roadmap"). Regression vs round-1, which had no bracket pattern
to blind and so fell back to the correct heading (repro12 bracket row:
2/1/50 at round-1, 4/3/75 at HEAD).

Fixed by hoisting one tokenizeHeadings(content) call
(currentMilestoneHeadings) shared by computeSectionEnd and the
preambleCutoff scan, which now iterates that same fence-aware token
list instead of a raw regex. HeadingToken.text is already hash-stripped
and trimmed, so isBracketMilestoneBoundary needs no `^#{1,3}\s+`
re-derivation at this site (that spelling would not match h.text — a
note the round-2 review called out explicitly, confirmed while
porting). selectedBracketId stays `null` here, unchanged from the B1
commit's same-milestone-exclusion reasoning.

DISCLOSED, not fixed (explicitly out of scope per the round-2 review's
own minimal-fix note): the LEGACY (non-bracket) anyMilestonePattern
raw-match path shares the identical fence-blindness hazard and stays
byte-identical — a bracket repo whose preamble has a fenced
VERSION-BEARING heading still has the legacy raw-match win the
earliest-of-either min() (repro12's LEGACY control: 4/3/75, unchanged
across base/round-1/HEAD/this commit). Pinned here so a future reviewer
files this as a known, pre-existing gap rather than a new regression.

Tests: new describe block "#612 PR-2 Blocker 3 round-2: preambleCutoff
is fence-aware (bracket branch only)" — RED-turned-GREEN for repro12's
bracket row and repro11's mechanism (fence balance + non-degraded
phaseCount + correct per-directory admission), a PIN for repro12's
LEGACY control (the disclosed gap, explicitly unchanged), and a PIN for
repro10 A3 (a fenced heading INSIDE the current section must still not
terminate it).

Full suite green (1072/1072 across the targeted adr-612 + roadmap-
parser + state + phase-id + markdown-sectionizer files); node

* fix(#2761): scope cmdStateSync's disk scan by milestone under bracket (Major 1)

Gate-2 adversarial review Major 1: `state sync` wrote a Progress
PERCENT computed from an UNFILTERED whole-disk scan, beside the
milestone-scoped total_phases/completed_phases it writes into the same
STATE.md via the refreshed frontmatter (syncStateFrontmatter ->
buildStateFrontmatter, which has always applied getMilestonePhaseFilter
for the READ path). cmdStateSync's own `fs.readdirSync` chain (the
WRITE-path scan) never called the milestone filter at all, unlike
buildStateFrontmatter's identical-purpose scan. One command therefore
wrote two contradictory numbers into one file: on the ADR-canonical
version-less bracket fixture (4 dirs, 3 complete; asserted milestone =
2 phases, both complete), base wrote total_phases:2/completed_phases:2
(correct, from the READ derivation) alongside body Progress 75% (wrong
— from the unfiltered WRITE derivation; repro3).

Fixed by threading `getMilestonePhaseFilter(cwd)` through the same
`.filter()` chain buildStateFrontmatter already applies, gated on
`syncConvention === 'bracket'` (falling back to a pass-all predicate
otherwise) — so totalDiskPlans/totalDiskSummaries/diskCompletedPhases/
syncTotalPhases become milestone-scoped under bracket, byte-identical
under legacy.

DEVIATION (approved, stated plainly): an earlier phrasing of this fix
called for mirroring buildStateFrontmatter's filter UNCONDITIONALLY.
Implemented GATED instead — an unconditional filter would ALSO move
every LEGACY repo's persisted percent, since the milestone-scoping-vs-
whole-disk divergence this closes is engine-wide, not bracket-specific.
The gate keeps legacy byte-identical, which is the binding constraint:
this is a bracket read-path PR, not a legacy behavior change.

Nit 2 (informational, no code change): 10 calls to
extractCurrentMilestone on a legacy repo cost 10 config.json
existsSync + 10 readFileSync (0 before B3); accepted, unmemoized cost,
unaffected by this commit.

Also folds in two minors from the round-2 review:
- Corrects .changeset/2761-bracket-read-tolerance.md: the sibling-
  exclusion sentence now states it holds at any heading level 1-3 and
  across a milestone split over two headings (true again now that
  Blockers 1 and 2 are fixed); the percent sentence states plainly that
  `state sync`'s body percent is now milestone-scoped under bracket,
  and unaffected under legacy.
- Records the read/write scoping divergence at currentMilestoneRawRanges
  (src/roadmap-parser.cts) in a comment: it did not receive B1/B2's
  bracket boundary fixes, currently harmless (its only consumer falls
  back to whole-content mutation, and every mutation there is still
  Phase-labelled-only, not bracket-widened), but live the moment the
  write path is bracket-widened — flagged so a future PR closes it in
  lockstep with that work, not after.

Tests: 6 pre-existing tests in tests/adr-612-bracket-phase-counting.test.cjs
needed fixture updates, not logic changes — they used the default
single directory (`GSD.02-01-setup`, phase "01"), which the SENTINEL/
retirement/mixed-heading fixtures in those tests never declare as a
real phase (only 04/05/06/999/etc are declared). Before this fix,
cmdStateSync's unfiltered scan counted that off-roadmap directory
anyway; after this fix the milestone filter correctly excludes it,
which for several of these fixtures made `state sync` a no-op (the
computed 0% coincided with STATE.md's initial template default) and
broke `syncedTotal()`/`syncedPercent()`'s ability to observe anything.
Updated each to pass an EXPLICIT directory naming one of the fixture's
REAL declared phases, preserving each test's original numerator/
denominator intent. One test — "shape 2 WRITE" — was substantively
rewritten: it was a CHARACTERIZATION of the Major 1 bug itself ("the
DISCLOSED legacy gap, mirrored — not closed"), and now correctly pins
bracket closing to 33% (agrees with the read path) while legacy stays
at the disclosed 60% (unchanged, deliberately, per the gating decision
above).

Full suite green: `npm test` 1449/1449 (0 fail, 0 skipped, 0 todo,
single-shard "all" run — includes issue-2765-brace-expansion-lockfile
passing); `npm run lint:ci` clean (0 errors; 2 pre-existing timing-
assertion warnings in files this PR does not touch); node

* fix(#2761): preambleCutoff identity is offset- and child-aware (round-3 Blocker 1)

Gate-2 round-3 re-verify Blocker 1 (NEW): the round-2 B1 deviation
(39c42a89) threaded `selectedBracketId` as the real value at
computeSectionEnd but as bare `null` at the preambleCutoff scan. The
deviation's rationale — "the selected heading's own occurrence is
always a correct earliest answer" — was right, but `null` disables the
same-milestone check for EVERY candidate, not just the selected one.
Any bracket-shaped heading earlier than the selected milestone was
accepted as a boundary regardless of identity: a same-id checklist/
overview heading preceding the version-bearing selected heading (cases
A, B — the version lands on the LATER half of a split, or a plain
overview heading with no "(Phase Details)" spelling), or a DIFFERENT-id
bracket-shaped PROSE heading with no children of its own sitting above
the current milestone's content (case D — `## [ADR.612] Heading
convention used by this roadmap`). In every case the region between
that false boundary and the real sectionStart was silently dropped —
a completed phase vanished and `state sync` persisted a confident 0%
where base and round-1 both correctly wrote 50%. Regression vs base
AND round-1 (not merely "under-fixed", per the round-3 review's own
severity note).

Fixed with two changes, both scoped to the preambleCutoff scan only
(computeSectionEnd already threads the real `selectedBracketId` and is
untouched):

(a) `h.offset === sectionStart` now bypasses BOTH the same-milestone
    check inside isBracketMilestoneBoundary (passing the REAL
    `selectedBracketId` for every other candidate) and the new child
    rule below — the selected heading's own position is definitionally
    the correct answer, so neither discriminator should run against it
    (rejecting it would mean rejecting the heading against ITSELF).
    Closes cases A and B — verified by the reviewer's own one-liner,
    reproduced here.

(b) New `bracketHeadingHasMatchingChild`: an otherwise-accepted
    candidate (bracket-shaped, not phase-tail-shaped, not the same id
    as the selected milestone) must ALSO have a next-strictly-deeper
    heading carrying its OWN bracket id to count as a boundary. This is
    what a genuine sibling milestone has (its own phase children share
    its bracket id — `## [GSD.01] Setup` / `### [GSD.01] 01: …`) and an
    unrelated bracket-shaped prose heading does not. A candidate with
    no such child at all (childless — e.g. an empty prior milestone, or
    one immediately followed by a same-or-shallower heading) degrades
    to NOT a boundary — over-inclusive, the safe direction: its own
    heading text stays in the preamble, contributing nothing to any
    phase count (not phase-shaped). Closes case D, which (a) alone does
    not — verified: without this rule, `[ADR.612]`'s prose heading is
    indistinguishable from a genuine prior sibling at this site.

As a side effect, also neutralizes Nit 2 (a colon-less `[GSD.02] 05`
heading spuriously terminating the preamble): a colon-less bracket
heading is not phase-tail-shaped so isBracketMilestoneBoundary alone
would accept it, but it is — precisely because it is malformed/
incomplete rather than a real milestone — childless, so the child rule
rejects it too. Pinned.

Known interaction with the fence-blind SELECTION path (disclosed by
the reviewer, not introduced here, tracked for the next commit): when
`sectionPattern` selects a FENCED version-bearing heading (an
extremely pathological shape — a fenced example whose text happens to
match STATE's asserted version), no token exists at `sectionStart`, so
the `h.offset === sectionStart` bypass never fires and the loop falls
through to the ordinary same-id / child-rule checks. This composes
with the round-3 Major 1 fix (next commit) rather than introducing a
new defect — SELECTION itself is untouched by any of this — but is
worth stating plainly rather than rediscovering.

Tests: new describe block "#612 PR-2 Blocker 1 round-3: preambleCutoff
identity is offset- and child-aware" — RED-turned-GREEN for cases A, B
(rv-attack1) and D (rv-attack1b) with syncedTotal()/syncedPercent()
assertions (the persisted 0% is the point), a PIN for a genuine prior
sibling with real children (still excluded), a PIN for a childless
prior sibling (degrades to not-cutting, over-inclusive/safe), a PIN
for the colon-less Nit 2 shape, and the reviewer's rv-mech1 mechanism
re-run as a proper test (scope now equals the full input document,
phaseCount 2, both dirs accepted).

* fix(#2761): fence-aware version/emoji half of preambleCutoff on the bracket branch (round-3 Major 1)

Gate-2 round-3 re-verify Major 1 (NEW): ff6bf0a8 (round-2 Blocker 3)
made the BRACKET half of preambleCutoff's "earliest milestone-shaped
heading" search fence-aware, but left the VERSION/emoji half a raw
`content.match` even on the bracket branch. A fenced VERSION-BEARING
example heading in a bracket repo's preamble (ADR-612's own docs
illustrate the LEGACY heading shape exactly this way, inside a fenced
authoring-guide block) was still textually the earliest match for that
raw regex, winning the min() and un-suppressing a wrong persisted 75%
that base correctly suppressed (rv-attack3c fixture C1: base
suppressed the percent entirely — `isMilestoneBounded` false — HEAD
wrote 75% where truth is 50%).

Fixed by deriving the version/emoji half from the SAME fence-aware
`currentMilestoneHeadings` token list as the bracket half, on the
bracket branch only — the exact `/^Phase\s+\S/i` / `/v\d+\.\d+|✅|📋|🚧/i`
pair `computeSectionEnd` already uses against `h.text`. The non-bracket
(legacy) path is untouched: it keeps the raw `content.match`, byte-
identical to before, including its own fence-blindness (repro12's
LEGACY control, pinned unchanged in the round-2 Blocker-3 test block —
not re-pinned here to avoid duplicating an already-covered assertion).

Not rated Blocker (per the review) because it is not a regression vs
round-1 and the fixture (a version-BEARING fenced example in a bracket
repo) is rarer than the already-fixed bracket-heading case; still
fixed now rather than disclosed, per this arc's own precedent (every
prior "disclose instead of fix" call in this PR has been overturned on
re-review).

Tests: new describe block "#612 PR-2 Major 1 round-3: preambleCutoff's
version/emoji half is fence-aware on the bracket branch" — RED-turned-
GREEN for case C1 (readTotal + syncedPercent, so the persisted 75% is
directly observed, not just the read-path total), PIN for case C2 (the
already-fixed fenced-bracket-heading shape, unchanged).

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* chore(#2761): correct changeset claims + mark runtime-gated BASE_SITES row (round-3 minors)

Gate-2 round-3 re-verify Minor 2: three changeset sentences in
.changeset/2761-bracket-read-tolerance.md were overstated in a new
direction after round-2:

- The split-milestone claim ("across a milestone split over two
  headings") was true only when the version-bearing heading came
  FIRST (repro8 case 1); false when it came LATER (round-3 Blocker 1
  case A). Now restated to say plainly "with the version-bearing
  heading in EITHER position" — true again now that round-3's Blocker
  1 fix lands earlier in this range.
- The "counted from the phases... rather than from every directory on
  disk" claim was false on cases A/B/D (a strict subset of the
  milestone's own phases). Restated as "ALL of the phases... not a
  subset", and extended to state that an unrelated bracket-shaped
  heading with no phase children of its own (case D's `[ADR.612]`
  shape) does not truncate the milestone either — true now, not before.
- "Each widened read is SELECTED by the project's phase_id_convention"
  was literally false for BRACKET_PHASE_TAIL_RE, which is RUNTIME-gated
  (via its only caller, isBracketMilestoneBoundary, itself only
  consulted when bracketBoundaryActive) rather than selector-gated.
  Restated behaviourally: "every widened read ENGAGES only when the
  project's resolved phase_id_convention is bracket" — true for both
  gating mechanisms, so it no longer implies a selector call this site
  does not make.

Minor 1: the STRUCTURAL IDENTITY test's BASE_SITES row for
BRACKET_PHASE_TAIL_RE (added in the B2 commit) asserts a property of
`phaseHeadingPrefixSrcFor` — the function — not of the call site; it
would pass unchanged even if the site were deleted. Safety at that
specific site rests entirely on a runtime gate the test cannot see.
Added `runtimeGated: true` to the row and threaded it into the
generated test's own title (`… [runtime-gated, not selector-covered]`),
so the gating mechanism is visible in test OUTPUT, not only in a source
comment that could drift silently.

No production code changed. Targeted suite green (48/48 in the
affected file); `node scripts/changeset/lint.cjs` ok; eslint clean.

* fix(#2761): harden round-3 preamble cutoff — subtree child scan + level cap

Team-lead review of f87bba0e found two edges in the round-3 preamble-
cutoff code, both hardened here.

AMENDMENT 1 — bracketHeadingHasMatchingChild (2e06aef5) checked only
`headings[index + 1]`, the IMMEDIATE next heading, not the candidate's
whole subtree. A genuine prior sibling milestone whose section opens
with a non-bracket subsection before its first phase heading
(`## [GSD.01] Setup` / `### Notes` / `### [GSD.01] 01: Old`) was
therefore wrongly rejected as a boundary — its real phase heading sits
TWO headings deep, not one — leaking its entire section into the
preamble unstripped.

CONFIRMED RED, not merely theoretical (built and ran the fixture
against f87bba0e before touching the fix, per instruction): scope
membership DOES drive the disk-side filter on this shape.
`GSD.01-01-old`'s directory was wrongly admitted into the CURRENT
milestone's filter via the leaked heading's qualified key
(`GSD.01-01`) — 3/2/67% where truth is 2/1/50%.

Fixed by scanning the candidate's full SUBTREE: continue past a
non-matching deeper heading instead of returning false on the first
one; only a same-or-shallower heading actually closes the subtree and
yields "no match found". A candidate whose entire subtree closes with
no same-id hit (including a genuinely childless one) still degrades to
`false` — over-inclusive, safe, unchanged from before.

AMENDMENT 2 — c483552a ported the version/emoji half of preambleCutoff
to the token-based scan with no level cap; the raw
`content.match(anyMilestonePattern)` it replaced was anchored
`^#{1,3}\s+`. A level-4+ version-bearing heading in the preamble
(`#### v2.0 notes`) therefore won the scan on the bracket branch where
the raw pattern — and the legacy path, unaffected — ignores it
outright. Fixed with `if (h.level > 3) continue;`, mirroring the
depth-sanity cap isBracketMilestoneBoundary already applies to the
bracket half of this same scan.

Tests: new describe block "#612 PR-2 round-3 hardening: subtree child
scan + level cap on preambleCutoff" —
- RED-turned-GREEN for the Notes-intervening fixture: exact 2/1/50 (was
  3/2/67), plus the disk-filter observable (`GSD.01-01-old` now
  correctly excluded).
- PIN for the level-4 preamble heading: the scope now PRESERVES the
  heading's text (was silently dropped before this fix — harmless in
  this minimal fixture's total_phases specifically, since the dropped
  text carries no phase-shaped content, but a real correctness gap
  against the raw pattern's own ceiling) — asserted via scope content,
  not total_phases, since that number is invariant here either way.
- PIN for the LEGACY control on the same level-4 shape — unchanged,
  confirming the raw content.match path is untouched.

Re-verified the existing genuine-prior-sibling and childless-sibling
pins (round-3 Blocker 1 commit) still pass under the subtree scan —
both fixtures' outcomes are unchanged since their same-id hit (or its
absence) was already at the first deeper heading.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 942/942 pass (939 + 3 new). node scripts/lint-phase-id-drift.cjs

* fix(#2761): bracketHeadingHasMatchingChild requires a same-id PHASE child (round-4 Blocker 1)

Gate-2 round-4 re-verify Blocker 1 (NEW): the round-3 hardening's
subtree scan (fbfd0fca) proved SAME-ID-NESS but never asked whether
the matching child was PHASE-shaped. Case F1 re-opens round-3's case D
one heading later: `## [ADR.612] Heading convention` is followed by
its OWN sub-heading `### [ADR.612] Examples` — same bracket id as the
candidate, but MILESTONE-shaped (a name, no digit-then-colon), not a
phase. Same-id-ness alone satisfied the subtree scan and re-cut the
preamble at exactly the shape the round-3 hardening was written to
close.

Failing input: `## [ADR.612] Heading convention` / `### [ADR.612]
Examples` (prose) / `### [GSD.02] 01: One` (the current milestone's
own first phase, now unreachable) / `## [GSD.02] v2.0: Foundation` /
`### [GSD.02] 02: Two`. Truth 2/1/50. HEAD read 1/0/0, and `state sync`
reported "nothing to do" (exit 0, `{synced:true,changes:[]}`) because
its wrong 0% happened to equal the STATE.md seed — a half-done
milestone read as untouched with no write-path signal at all.

Fixed with the reviewer's one-conjunct addition: a same-id child only
counts if it is ALSO phase-tail-shaped (`BRACKET_PHASE_TAIL_RE`) — the
same single-owner discriminator `isBracketMilestoneBoundary` already
uses one level up for the identical distinction (phase vs milestone),
reused here rather than re-derived. This is exactly what the
changeset's own wording already claimed ("no phase children of its
own") — the code now matches the sentence rather than the other way
around.

Docstring updated at the function itself: the rule is "same-id PHASE
child", not "same-id child".

Tests: new describe block "#612 PR-2 round-4 Blocker 1: the same-id
child must be PHASE-shaped" — RED-turned-GREEN for F1 with
syncedTotal()/syncedPercent() (the persisted 0% — and the
report-nothing-to-do write-path silence — is the point), PINs for F11
(colon-less same-id child) and F11b (bullet-only phase list): both
correctly stay excluded either way, and the leak the phase-shape
requirement newly creates for these two shapes is INERT — a colon-less
heading forms no qualified key (getMilestonePhaseFilter's own
phase-heading pattern requires the colon too) and a bracket bullet
never matches the legacy-only BULLET_PHASE_LINE_PATTERN — confirmed
directly via getMilestonePhaseFilter, not merely inferred. Re-verified
the four existing child-rule pins (F2 subtree-closure, F3 deep-nested
same-id, F4 level-4 same-id, F5 childless-at-EOF) are unaffected by the
phase-shape requirement, since every one of them already used a
colon-bearing same-id child.

* fix(#2761): fence-aware phase counting, milestone bounding, and bracket-fallback selection (round-4 Major 1)

Gate-2 round-4 re-verify Major 1 (NEW): roadmapPhaseCount is a
fence-blind raw `.exec()` over the scope string, duplicated in TWO
independent copies (buildStateFrontmatter's read path, cmdStateSync's
write path). With the bracket alternative now compiled into it (#612),
a fenced EXAMPLE phase heading in the preamble inflates total_phases
and persists a wrong percent that base got right. Two further
fence-blind sites participate: isMilestoneBounded (a raw
`.test(roadmapRaw)`) and the bracket-fallback SELECTOR inside
extractCurrentMilestone (a raw `content.matchAll`, only reachable when
version-string selection finds nothing).

Failing inputs:
- F10 (clean isolate, version-bearing selection): a fenced
  `### [GSD.02] 05: Example phase` in the preamble inflates
  total_phases 2->3, persisting 33% where truth is 50%. LEGACY control
  on the same shape is correct on every build — not a pre-existing
  hazard being inherited, bracket-only.
- F9 (version-less selection): a fenced example carrying the project's
  OWN milestone id additionally confuses the bracket-fallback selector
  (the fenced heading gets SELECTED), compounding with the same
  fence-blind counter. base suppressed the percent; round-1 and HEAD
  both wrote 33%.
- F12 (isMilestoneBounded isolate): the ONLY `[GSD.02]` heading in the
  document is inside a fence, and the asserted milestone genuinely has
  no section at all — HEAD persisted 67% where base correctly
  suppressed the percent (the milestone is absent from the roadmap).

Fixed at the CONSUMER level, not the producer — extractCurrentMilestone's
returned scope string is deliberately UNCHANGED, since every other
consumer of that string needs its full content fidelity and legacy
identity forbids touching the shared string (this branch's own
precedent, ff6bf0a8/c483552a, was producer-level; here the ruling is
consumer-level because the string is shared far more broadly than the
two round-3 fixes' narrower producer edits):

(a) New `countRoadmapPhaseHeadings` (src/state.cts, immediately above
    extractRetiredPhaseNumbers) — ONE shared implementation for both
    call sites, replacing two independently-maintained copies. BRACKET
    convention counts via `tokenizeHeadings(scope)` at levels 2-4,
    testing each heading's hash-stripped text directly — fence-aware by
    construction, since tokenizeHeadings never produces a token for a
    fenced line. LEGACY convention keeps the exact pre-existing raw
    `.exec()` loop, byte-for-byte. A pre-existing, deliberately
    PRESERVED asymmetry between the two original call sites — the read
    path always excluded a bare `/^999\b/` token, the write path never
    did — is threaded through as an explicit
    `includeUnconditional999Check` parameter per call site, so sharing
    the implementation does not silently unify (and thereby move)
    either total.
(b) isMilestoneBounded's bracket branch now scans
    `tokenizeHeadings(roadmapRaw)` for a matching heading (level <= 3)
    instead of a raw regex test. Legacy version-string branch untouched.
(c) The bracket-fallback SELECTOR now builds its candidate set from
    `tokenizeHeadings(content)` instead of `content.matchAll`,
    reconstructing a match-shaped array so every downstream consumer of
    `headingMatches` sees the identical shape the raw-regex path always
    produced. This is the ONE site in this entire arc where SELECTION
    itself changes — selection SEMANTICS are otherwise unchanged (same
    pattern, same first-match-wins by document order); only the
    candidate set is now fence-aware. Pinned that unfenced selection is
    byte-identical.

Zero drift measured across the full historical corpus (repro2-13,
rv-attack1/1b/3c, rv-mech1, rv2-amend1/2, and F1-F11b) except the three
target fixtures.

Tests: new describe block "#612 PR-2 round-4 Major 1: four fence-blind
sites on the bracket path" — RED-turned-GREEN for F10 (with
syncedTotal()/syncedPercent()) and F9 (both layers), PINs for F10's
LEGACY control and F10c (non-phase-shaped fence, unaffected either
way), RED-turned-GREEN for F12 (asserts the percent KEY is absent from
`state json`'s output and that `state sync`'s body stays at its
unmodified seed — the persisted-suppression signal, not merely a
total_phases number), and an explicit PIN that unfenced bracket-fallback
selection (first real milestone-shaped heading wins, no fences
involved) is unaffected.

* chore(#2761): correct docstring overstatement + stale consumer-count sentence (round-4 minors)

Gate-2 round-4 re-verify Minor 1 + Nit 1. No production code changed.

Minor 1: bracketHeadingHasMatchingChild's own docstring said a
rejected (no-same-id-PHASE-child) candidate's degrade "contributes
nothing to any phase count" — true of the candidate's OWN heading
text, but not of its SUBTREE, which is what actually stays in the
preamble. F7 (`## [GSD.01] Setup` / `### [GSD.07] 01: Foreign`) shows
a DIFFERENT-id bracket PHASE heading inside a rejected candidate's
subtree DOES form a qualified key and CAN admit a foreign directory —
3/2/67%, stable across base, round-1 and HEAD (base via its own
pass-all degrade). Not a regression, still the declared over-inclusive
/ never-under-inclusive safe direction — the comment now says that,
with F7's numbers cited, at the call site that actually decides
`isBoundary` (roadmap-parser.cts's preambleCutoff loop) rather than
only at the helper's own definition.

Minor 2 (changeset) — VERIFIED, no wording change needed: re-ran F1,
F9, F10, F12 at this HEAD. The "no phase children of its own... does
not truncate it either" sentence (naming the `[ADR.612]` shape
directly) is now literally true — F1 reads 2/1/50. The "counted from
ALL of the phases... not a subset" sentence is now true on every
measured shape — F1/F9/F10 all read 2/1/50, F12 correctly suppresses
the percent. No carve-out for F9/F10 is needed since round-4 Major 1
(3be5c412) closes both; per the fix-round instruction to "only carve
out anything genuinely left," nothing is.

Nit 1: tests/adr-612-bracket-heading-selection.test.cjs's runtimeGated
row claimed `BRACKET_HEADING_INTRO_RE` has "no other consumers" — true
when round-3's f87bba0e wrote it, stale since 2e06aef5 (round-3's own
earlier commit) had already added two more uses inside
bracketHeadingHasMatchingChild. Corrected to state the true count
(three consumers) and re-confirm the conclusion is unaffected: all
three are still nested inside the same bracketBoundaryActive runtime
gate, and BRACKET_HEADING_INTRO_RE is built from BRACKET_ID_SRC, not
phaseHeadingPrefixSrcFor, so it was never a selector site regardless of
consumer count.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`

* fix(#2761): restore the bracketId guard in countRoadmapPhaseHeadings (round-5 Blocker 1)

Gate-2 round-5 re-verify Blocker 1 (NEW, introduced by 3be5c412): the
merge that created the shared countRoadmapPhaseHeadings helper dropped
the `bracketId && ` guard both original inline loops carried before
calling isSentinelPhaseId. Every other isSentinelPhaseId call site in
src/ (roadmap-parser.cts, roadmap.cts, validate.cts x2, verify.cts)
keeps the guard; state.cts's shared counter was the only one of seven
without it.

When the phase-heading-intro grammar's LEGACY alternative matches (a
`### Phase 00:` heading in a `phase_id_convention: "bracket"` repo —
the mid-migration shape this PR exists for), the bracket capture group
is `undefined`, so the unguarded call became
`isSentinelPhaseId("undefined-00", 'bracket')` — measured TRUE, so
phase 00 (and 000, 0a, 0.5, 999.1 — any token whose splice with the
literal string "undefined" happens to fall in a sentinel range) was
silently dropped from the denominator. `getMilestonePhaseFilter` (which
still carries its own guard) counts the phase and admits its directory
regardless, so the filter and the counter disagree — a half-done
milestone reads as 100% complete, persisted.

One-line fix, restoring the guard every sibling call site already has:

    if (bracketId && isSentinelPhaseId(`${bracketId}-${token}`, 'bracket')) continue;

Line count: `git diff --stat src/state.cts` -> 1 file changed, 1
insertion(+), 1 deletion(-).

Tests: new describe block "#612 PR-2 round-5 Blocker 1:

GREEN for G3 (3/2/67, was 2/2/100) and G3d (the mixed bracket+legacy
mid-migration shape, same numbers) with syncedTotal()/syncedPercent(),
PIN for G3's legacy control (unaffected), PIN for G3b (isolates the
counter with no directory to admit), PIN for G3c (legacy 01/02 only,
no sentinel-shaped token present).

* fix(#2761): extractRetiredPhaseNumbers is fence-aware on the bracket path (round-5 Major 1)

Gate-2 round-5 re-verify Major 1 (NEW) — a FIFTH fence-blind site on
the bracket path, missed by 3be5c412's own enumeration of "four".
extractRetiredPhaseNumbers' line scan (`scope.split(/\r?\n/)`) has no
fence awareness. This PR compiles the bracket alternative into
`introSrc` ("the retirement filter has to widen with the counter it
protects" — the function's own pre-existing comment), so a FENCED
authoring EXAMPLE showing the #1514 retirement gesture in bracket
spelling is now indistinguishable from a real one: it retires a
genuine phase, shrinking the denominator and persisting a confident
100% where base correctly read 50%.

Fixed with the SAME consumer-level ruling this arc has used at every
other fence-blind site, reusing markdown-sectionizer's existing
exported `stripFencedCode` rather than hand-rolling a second fence
parser (single-owner rule) — retirement lines are BULLETS, not
headings, so `tokenizeHeadings` doesn't serve here; `stripFencedCode`
is the general-purpose fence stripper the tokenizer itself is built on.
Gated on `convention === 'bracket'`; the LEGACY line scan stays the raw
`scope` string, byte-identical — its own fenced-example hazard is
pre-existing (wrong at base too) and out of scope.

Line count: `git diff --stat src/state.cts` -> 1 file changed, 9
insertions(+), 2 deletions(-) — one import added, four lines inside
the function (a comment + the `scanScope` computation + the changed
`.split()` call).

Tests: new describe block "#612 PR-2 round-5 Major 1:
extractRetiredPhaseNumbers is fence-aware on the bracket path" —
RED-turned-GREEN for G2 (fenced example in the preamble) and G2b (the
same example placed INSIDE the milestone section, ruling out a
preamble-scoping artifact — the site itself was fence-blind wherever
the fence sits), PIN for the LEGACY control (unchanged, pre-existing,
out of scope — base is wrong on this shape too).

Also folds in the "four fence-blind sites" correction: 3be5c412's
commit message and any restatement of it should read FIVE going
forward; this commit's own message states the count correctly.

Targeted suite green: `node --test tests/adr-612-*.test.cjs

* fix(#2761): state sync's counter excludes the bracket 999 icebox token (round-5 Major 2)

Gate-2 round-5 re-verify Major 2 (NEW) — `includeUnconditional999Check`
left `state json` and `state sync` reporting different totals for one
bracket repo. Under bracket, READING-B puts the sentinel in the
bracket, so `isSentinelPhaseId("GSD.02-999", 'bracket')` is false —
the `/^999\b/` TOKEN rule is the only thing excluding a
`### [GSD.02] 999:` icebox heading, and it ran on the read path
(buildStateFrontmatter, `true`) and on getMilestonePhaseFilter
(unconditional), but not on cmdStateSync's own counter (`false`). One
`state sync` call could leave a single STATE.md with its own
frontmatter (percent 50, from the read-path re-sync inside
writeStateMd) and body (percent 33, from the write-path counter that
alone still counted the icebox heading) disagreeing — falsifying this
PR's own stated invariant that sharing countRoadmapPhaseHeadings made
"the two counters must see the same phases" structural.

Functional change is one argument, exactly as specified: the write
call site now passes `syncConvention === 'bracket'` instead of the
literal `false`. `syncConvention === 'bracket'` is `false` for every
non-bracket value, so the LEGACY path resolves to the exact same
`false` it always did — this file's own pre-existing, deliberately-
unchanged read/write divergence on that path is untouched. The READ
site (`:1860`) is NOT touched — its historical behaviour applied
`/^999\b/` to legacy and bracket alike, so changing it would move
legacy READ totals, exactly the class of mistake this arc's own
Blocker 1 (this round) was.

Line count: the functional change is ONE argument
(`false` -> `syncConvention === 'bracket'`); the surrounding comment
was rewritten because the previous one asserted the now-superseded
behaviour ("preserving this file's pre-existing... divergence... a
bare 999 token is not excluded here") and leaving it would mislead the
next reader — not a structural change.

Tests: new describe block "#612 PR-2 round-5 Major 2: state sync
excludes the bracket 999 icebox token like the read path" —
RED-turned-GREEN for G1, asserting `state sync`'s body percent equals
`state json`'s own percent (both 50, not 33 vs 50), PIN for G1's
legacy control (33 vs 50 unchanged, deliberately).

* chore(#2761): restore indent parity at the two line-start-anchored bracket-heading reconstructions (round-5 Minor 1)

`HeadingToken.offset` (tokenizeHeadings) is the LINE-START character offset,
not necessarily the `#` character's own offset — a ≤3-space-indented ATX
heading has both. Two round-4 reconstructions built on tokenizeHeadings
inherited this gap and accepted indented headings their raw, line-start-
anchored predecessors (`^#{1,3}\s+\[...`) never matched:

  1. roadmap-parser.cts's bracket-fallback SELECTOR (extractCurrentMilestone,
     ~line 377) — an indented, version-less `[GSD.02]` milestone heading
     could be reconstructed into headingMatches, then mis-parsed downstream
     (selectedBracketId null, level fallback to 1), leaking a SIBLING
     milestone's phases into the counted scope (G6: HEAD read 3/2/67 instead
     of 2/1/50 — a real phase heading's own directory belonging to the NEXT
     milestone got counted).

  2. state.cts's isMilestoneBounded (~line 1571) — the same gap let an
     indented-only `[GSD.02]`-shaped heading wrongly bound a milestone
     absent from the roadmap, un-suppressing a percent that should stay
     suppressed (mirrors round-4's F12 fenced-only case, but via indentation
     instead of a fence).

Fix: one added conjunct per site — `content[h.offset] === '#'` (source-named
`roadmapRaw` in state.cts) — filtering to tokens whose LINE-START offset IS
the `#` character, i.e. exactly the set the raw line-start-anchored regex
would ever have matched. Restores byte-for-byte raw parity; no other logic
in either function changes. computeSectionEnd and the preamble version/
emoji-token scan are untouched, as instructed — they consumed tokenizeHeadings
output before this arc and are out of scope here.

Also corrects roadmap-parser.cts's now-provably-false docstring claim that
`h.offset` is unconditionally "the same `#`-character coordinate space
`content.match().index` used" — true only for the survivors of the new
filter, not for every token tokenizeHeadings produces.

Line count: the FUNCTIONAL change is exactly 2 lines (one added `&&` conjunct
per call site — `git diff --stat` on the two source files shows 20
insertions/7 deletions, but only those 2 lines change behavior; the rest is
docstring/comment rationale, per this round's "state the line count" ask).

TDD: both fixtures verified RED at HEAD before this commit, GREEN after,
via /tmp/pr612rev/rv5-attack.cjs G6 and a locally-authored isMilestoneBounded-
isolating probe (G6 alone doesn't distinguish the two sites — its unindented
phase headings already satisfy isMilestoneBounded's loose prefix regex
either way, so a second, indentation-only fixture was needed to prove that
site's fix is not a no-op; verified by temporarily reverting just that one
conjunct, confirming 100%-wrongly-bounded RED, then restoring it, confirming
suppressed-percent GREEN).

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (G6): indented version-less bracket milestone heading — 2/1/50, not
    the pinned-before-fix 3/2/67.
  - PIN (G6c unindented control): identical document, no indent — 2/1/50
    unaffected on every build.
  - RED (isMilestoneBounded site, indented-ONLY): mirrors round-4's F12
    shape (fenced-ONLY → indented-ONLY) — percent stays suppressed instead
    of the pinned-before-fix wrongly-bounded 100%.

Full G1-G10 (rv5-attack.cjs) + G2b/G3c/G3d/G6c (rv5b.cjs) re-verified
zero-drift against TRUTH after this change. Targeted suite (adr-612-*,
roadmap-parser, state, verify): 962 -> 965 (+3), 0 fail.

* chore(#2761): changeset discloses counting-set narrowing + correct stale consumer-count sentence (round-5 minors)

FIX 5 (Minor 2): .changeset/2761-bracket-read-tolerance.md did not disclose
that bracket phase-heading counting is narrower than the raw-regex
predecessor in two ways the review's G4/G5 fixtures surfaced: a level-5
heading (`##### [GSD.02] 05: ...`) is no longer counted (the counter's
tokenizeHeadings scan caps at level 4, matching the selector/isMilestoneBounded
ceiling), and a space-less heading (`###[GSD.02] 05: ...`) is no longer
counted (CommonMark requires ≥1 space/tab after the hashes, which
tokenizeHeadings correctly enforces and the old raw regex did not). Both
G4 and G5 moved from round-1's wrong (inflated) values back to base's
original values as an incidental side effect of routing through
tokenizeHeadings — never a deliberate feature of this PR, and previously
undocumented. One clause added to the existing run-on paragraph; no other
wording in the changeset touched.

FIX 6 (Nit 1): tests/adr-612-bracket-heading-selection.test.cjs:76 —
`BRACKET_PHASE_TAIL_RE` has TWO consumers as of round-4's 65d257ce
(isBracketMilestoneBoundary's own use, plus bracketHeadingHasMatchingChild's
same-id-PHASE-child conjunct), not the "no other consumers" the comment
claimed. Same correction pattern round-4 already applied to this row's
BRACKET_HEADING_INTRO_RE neighbor (that sentence's own staleness was fixed
in 4d7184b8): note the true consumer count, confirm both stay nested inside
the same bracketBoundaryActive runtime gate (verified at
src/roadmap-parser.cts:178 and :250, both reached only through the
`if (bracketBoundaryActive)` block starting at :529), and record which
commit and which fix introduced the drift. Comment-only; no assertion
logic changed.

Line count: 2 files, 8 insertions / 2 deletions total — one added clause
in the changeset (1 line changed) and one comment block replacing the
single stale line in the test file (6 comment lines replacing 1).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 965/965 pass (comment/prose-only diffs, no test count change).
`node scripts/changeset/lint.cjs` and `npx eslint` on the touched files both

* fix(#2761): restore the bracketId guard on the bracket-only /^0\b/ sibling rule (round-6 Blocker 1)

Round-5's Blocker 1 was `isSentinelPhaseId("undefined-00")` — the merge
that introduced the shared counter dropped the `bracketId &&` guard on the
sentinel check. This is the identical failure one line further down, in the
sibling rule this PR itself added: when the phase-heading grammar's LEGACY
alternative matches (`### Phase 0:` in a `phase_id_convention: "bracket"`
repo — the mid-migration shape this PR exists for), `bracketId` is
`undefined`, and the unguarded `/^0\b/` fires on the bare token anyway.
Neither the LEGACY branch of this same function nor
`getMilestonePhaseFilter` has a `/^0\b/` rule at all, so the filter counts
the phase and admits its completed directory while the counter refuses to
count its heading — a milestone with an unstarted phase 02 persists as a
confident 100%.

`/^0\b/` matches `0` and `0.5` (word boundary before the `.`) but not `00`
(no boundary between the two zeros), which is exactly why round-5's G3/G3d
fixtures (`### Phase 00:`) never tripped this one — same defect class,
different token spelling.

Fix: one word, mirroring the guard round 5 restored two lines above —
`if (/^0\b/.test(token)) continue;` -> `if (bracketId && /^0\b/.test(token)) continue;`.

Expected and intentional side effect: `roadmap analyze` and `state json`
now disagree again on this bracket-repo shape (analyze phase_count=2, json
total_phases=3) — exactly as they already do under the legacy convention
today (verified via /tmp/pr612rev/rv6c.cjs on both conventions). That is
the counter regaining agreement with `getMilestonePhaseFilter` (the tighter
constraint — it is what actually decides `completed_phases`), not a new
break; the counter/filter disagreement is what was wrong.

Out of scope, deliberately NOT fixed here (Minor 1, disclosed via a PIN
test only): the bracket-SPELLED `### [GSD.02] 0:` shape has the same
counter/filter disagreement, but reads 2/2/100 on base too — never closed
by any build in this arc, so it is a pre-existing gap rather than a
regression this commit could introduce.

Line count: src/state.cts is exactly 1 insertion / 1 deletion (one word,
`bracketId && ` prepended to the existing condition).

TDD: T0 (`Phase 0:`) and T05 (`Phase 0.5:`) verified RED at HEAD before this
commit (json 2/2/100, sync body 100%) via /tmp/pr612rev/rv6b.cjs, GREEN
after (3/2/67 on both derivations, matching TRUTH). Zero-drift verified by
diffing the FULL corpus (rv5-attack, rv5b, rv4-attack, rv-attack1,
rv-attack1b, rv-attack3c, rv-mech1, rv2-amend1, rv2-amend2, rv6-attack
H1-H19, rv6b) between a pre-fix and post-fix build: the only differing
lines in the entire diff are T0, T05, and H14 — the three target fixtures.

New tests (adr-612-bracket-phase-counting.test.cjs):
  - RED (T0) + PIN (T0L legacy control)
  - RED (T05) + PIN (T05L legacy control)
  - PIN (B0, bracket-spelled `0` — base-parity characterization, Minor 1,
    not fixed this round)
  Round-5's own G3 test (`### Phase 00:`) already serves as the T00 pin —
  `/^0\b/` never matched `00`, so it is unaffected and untouched.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 965 -> 970 (+5),
0 fail. `lint-phase-id-drift.cjs` and `npx eslint` on touched files clean.

* chore(#2761): changeset re-attributes the phase-count level cap + discloses the bare-0 carve-out; correct two stale test comments (round-6 Minor 1 + Nits)

FIX 2 (Minor 1 — disclosure only, NOT a code fix): the bracket-SPELLED
`### [GSD.02] 0:` / `0.5:` shape has the same counter/filter disagreement
round-6's Blocker fixed for the legacy spelling, but it reads 2/2/100 on
BASE too — never closed by any build in this arc, so it is a pre-existing
gap rather than a regression this round could introduce. Two changes:

  - Pinned as a base-parity characterization: new PIN test (B0) in
    04b5a95f's describe block asserting the exact unchanged value with a
    comment stating why it's deliberately not touched.
  - .changeset/2761-bracket-read-tolerance.md: one qualifying clause added
    to the "counted from ALL of the phases … not a subset" sentence — a
    bare `0`/`0.x` phase token (however spelled) keeps `roadmap analyze`'s
    own pre-existing sentinel reading under bracket too, so it stays
    excluded from these counts. Carried over, not newly introduced by this
    PR — `roadmap analyze` has always read it this way.

FIX 3(a) — same changeset paragraph misattributed the phase counter's
2-4 level cap to "the milestone-boundary machinery in this PR" (the
selector, `isMilestoneBounded`, the preamble scan) — that machinery caps
at `###` (level ≤3), not 2-4. The 2-4 cap belongs to
`getMilestonePhaseFilter`'s own phase scan. Re-pointed the attribution;
the paragraph's earlier, correct ≤3 claim (selector/isMilestoneBounded)
is untouched.

FIX 3(b) — tests/adr-612-bracket-heading-selection.test.cjs:76-82 (added by
1395bd89, round-5's own Nit-1 correction) claimed both
`BRACKET_PHASE_TAIL_RE` consumers are reached "only through the
`if (bracketBoundaryActive)` block starting at :529". Verified at HEAD:
`bracketHeadingHasMatchingChild` is (only caller :593, inside that block).
`isBracketMilestoneBoundary` is not — it has two callers, an inline
`bracketBoundaryActive &&` conjunct at `:473` (inside `computeSectionEnd`)
and the `:529` block at `:567` — the very fact this row's own earlier
"exactly two callers" paragraph already stated correctly. Corrected the
mechanism claim; the CONCLUSION (every consumer is still gated on the same
flag) is unchanged, exactly as round-5's own Nit-1 fix left round-4's
conclusion unchanged when it corrected the consumer count.

FIX 3(c) — tests/adr-612-bracket-phase-counting.test.cjs:2311,2340 still
said "four fence-blind sites" after round-5 (357ba671) added a fifth
(the retirement scan) in its own block below. Reworded both the section
comment and the `describe()` label to read as historical scoping of
round-4's own fix ("the four sites known at round 4 … a fifth was found at
round 5, see its own block below") rather than a live exhaustive claim.

Line count: 3 files, changeset 1/1, heading-selection test 17/8,
phase-counting test 6/2 (comment/prose-only; B0's own PIN test landed in
04b5a95f alongside T0/T05 since it was investigated as part of that same
Blocker's defect class, not in this commit — noted here for the record).

Verified: targeted suite (adr-612-*, roadmap-parser, state, verify)
unchanged at 970/970 (comment/prose-only diffs, no test count change).
`npx eslint` and `node scripts/changeset/lint.cjs` both clean.

* fix(#2761): W021's bracket remediation hint stops pointing at a command that hard-errors (round-7 Minor 2)

`checkBracketCoherence`'s W021 (added by 94abf5df) attached the fix hint
`Run \`gsd-tools roadmap upgrade --convention bracket\` to migrate
(dry-run by default)` to every bracket-convention W021 — both sub-checks
(`missing-bracket` and `mismatch`) share the single `addIssue` call at
src/verify.cts:2255-2256. But `roadmap-command-router.cts:204` throws
unconditionally for any `--convention` value other than
`milestone-prefixed`:

  $ gsd-tools roadmap upgrade --convention bracket
  Error: Only --convention milestone-prefixed is supported

This contradicts the PR's own two disclosures: the changeset ("`bracket`
is a READ-path opt-in until the migrator and write path land") and
docs/CONFIGURATION.md:188 ("There is no bracket migrator and no bracket
emit yet"). Reachability is the exact mid-migration repo this PR targets —
any bracket project with one un-migrated heading gets an unfollowable
instruction on every `validate health`.

Fix: one string. Replaced the hint with what a user can actually do today —
manually align the heading's bracket milestone to its section — and named
the tracked future landing (#612 PR-3) instead of a command that errors.
The milestone-prefixed sibling hint at src/verify.cts:2240 (a different,
already-functional convention/command pair — verified against
roadmap-command-router.cts:65) is untouched.

Line count: src/verify.cts is exactly 1 insertion / 1 deletion (one string
literal).

No test in the suite previously asserted this string's content
(`grep -rn "upgrade --convention bracket" tests/` was empty), so the
unfollowable hint shipped unpinned — `lint-fix-has-regression-test.cjs`
would not have caught a string-only change without a new test. Added one:
asserts the fix string both (a) does not match `--convention bracket`
(the specific pinned-before-this-fix hazard) and (b) equals the new string
exactly, covering the invariant a future edit must not re-break: no
unsupported `--convention` value named in remediation text users are
expected to run verbatim.

Verified end-to-end (not just unit-level) via /tmp/pr612rev/rv7f.cjs: the
W021 issue's `fix` field now reads the new string; `gsd-tools roadmap
upgrade --convention bracket` (and its --dry-run variant) still correctly
hard-error — that command remains unsupported, only the hint text changed.

Targeted suite (adr-612-*, roadmap-parser, state, verify): 970 -> 971 (+1),
0 fail. `lint-phase-id-drift.cjs` clean; `npx eslint` on touched files:
0 errors (1 pre-existing unrelated no-elapsed-assertion warning, same file,
same line this arc's prior rounds already disclosed).

* chore(#2761): correct the bare-0 changeset disclosure + disclose W021's second sub-check (round-7 Minor 1 + Nit 1)

FIX 1 (Minor 1) — round-6's bare-0 changeset clause (1395bd89) was wrong in
three falsifiable ways:

  (a) Its own illustration (`### Phase 0:`) is exactly the LEGACY spelling
      04b5a95f made COUNTED. The residual exclusion after that fix applies
      only to the BRACKET-spelled token (`### [GSD.02] 0:`) — the clause
      named the wrong shape as its example.
  (b) "excluded from these counts" over-scoped the carve-out. The phase-0
      directory is admitted into `completed_phases`/`total_plans` in BOTH
      spellings (measured: B0 at HEAD has `completed_phases=2`,
      `accepts {"GSD.02-0-bootstrap":true}`). The exclusion that survives
      lives in `total_phases`/`phase_count` (heading counting) only.
  (c) The pre-existing "so `roadmap analyze` and `state json` report the
      same number" sentence (present since before this arc's bracket work)
      is now false for the bare-0 LEGACY-spelled shape: 04b5a95f's own
      commit message discloses this exact re-divergence as expected —
      `roadmap analyze` phase_count=2 vs `state json` total_phases=3 on T0
      — matching the disagreement legacy already carries today. The
      changeset still asserted unconditional agreement.

Rewrote both sentences: dropped the `### Phase 0:` example, scoped the
carve-out to `total_phases`/`phase_count`, named the bracket-spelled token
as the one that keeps analyze's sentinel reading, stated plainly that the
legacy-spelled form in a bracket repo IS counted (the mid-migration guard),
and qualified the "report the same number" claim to the `999` token, with
the bare-0 legacy-spelled shape named as the one exception and why.

FIX 3 (Nit 1) — `checkBracketCoherence` has always had two sub-checks
(its own docstring: "Two sub-checks, both surfaced as W021") but both the
changeset and docs/CONFIGURATION.md:188 described only the `mismatch`
sub-check. The `missing-bracket` sub-check — which fires on every
legacy-spelled heading in a bracket repo, the noisier of the two on a
mid-migration project — was undisclosed in both places. One clause added
to each.

Line count: 2 files, 1 line changed each (both are single-paragraph/
single-row files; git diff --stat reports 1/1 per file though several
distinct clauses were edited within that one line each).

Verified: `node scripts/changeset/lint.cjs` clean. Targeted suite
(adr-612-*, roadmap-parser, state, verify) unchanged at 971/971
(prose-only diffs, no test count change, no code touched).

* chore(#2761): resolvePhaseIdConvention's docstring no longer claims loadConfig drops the key

Upstream #2997 (aa7697fe, landed in `next` during this PR's final
verification) added `phase_id_convention: get('phase_id_convention') ?? null`
to `_baseConfig` in config-loader.cts — `loadConfig` now surfaces
`phase_id_convention` in its resolved config. This function's docstring
gave "loadConfig merges against CONFIG_DEFAULTS and drops keys it does not
know, and `phase_id_convention` is not among them" as the reason for
reading config.json directly instead of calling `loadConfig(cwd)`. That
rationale is now stale against live `next`.

Corrected the comment to state the two reasons that actually survive #2997:

  1. The workstream->root federation this function performs is a standalone
     resolution run against a GIVEN cwd, not necessarily the same base a
     `loadConfig(cwd)` call elsewhere in the codebase would federate from.
  2. Convention-ENUM validation is still #612 PR-4 work — this function
     returns the raw string unvalidated, exactly as the now-surfaced
     resolved key would.

Noted that #2997 surfacing the key makes consuming it from resolved config
(instead of re-reading config.json here) a natural PR-4 consolidation —
not this PR's scope. The "cycles were never the obstacle" close and every
other paragraph in the docstring (federation rationale, SCOPE note) are
untouched; they still hold.

Comment-only — no code behavior changed. This worktree's own history does
not contain aa7697fe (git merge-base --is-ancestor confirms neither branch
is an ancestor of the other; not rebasing per instruction), so this is a
textual correction against a documented external fact, not a functional
sync with upstream.

git diff --stat:
 src/planning-workspace.cts | 17 ++++++++++++-----
 1 file changed, 12 insertions(+), 5 deletions(-)

* fix(#2761): resolve phase_id_convention against the caller's workstream

`resolvePhaseIdConvention` took no workstream, so it resolved from
`planningDir(cwd)` — which falls back to `GSD_WORKSTREAM` only when its `ws`
argument is `undefined`. Every caller that passes a workstream by ARGUMENT
(they cannot set the env var per iteration) therefore read the convention from
the ROOT config while reading that workstream's ROADMAP.

Two reproduced consequences:

- A workstream that explicitly declares its own `phase_id_convention` had it
  ignored. Flipping ONLY the root config between bracket and milestone-prefixed
  changed which milestone that workstream extracted.
- `--workstream foo` and `GSD_WORKSTREAM=foo` disagreed on the same repo: the
  arg form fell through to the root config, the env form did not.

`resolvePhaseIdConvention(cwd, ws?)` now forwards `ws` to `planningDir`, and
both roadmap-parser call sites pass theirs — `extractCurrentMilestoneScoped`
(which already reads STATE from `planningDir(cwd, ws)`) and
`getMilestonePhaseFilter`'s lazy branch. `undefined` keeps the env fallback, so
convention-less call sites are byte-identical; `null` still means "explicitly no
workstream". The `undefined` vs `null` discriminator on `phaseIdConvention` is
untouched — only the base the `undefined` branch resolves FROM moves.

workstream-inventory's two sites (`countRoadmapPhases`, `inspectWorkstream`)
passed a literal `null` where they meant `undefined`, pinning every workstream
to the legacy grammar. On a bracket workstream whose milestone declares 3
phases that returned phaseCount 0 and fell back to the on-disk directory count;
it now returns 3. A non-bracket workstream is unchanged (legacy control pinned).

The workstream -> root federation is preserved: a workstream that declares no
convention still inherits the root, as config-loader does. That inheritance is
pinned so the fix cannot be over-applied into isolation.

* fix(#2761): classify missing phase details per occurrence, not per token

Under READING-B a phase's sentinel status lives in the BRACKET, so
`[GSD.999] 01` and `[GSD.02] 01` share a token and are not the same phase.
Both sides of the missing-detail check were keyed by the bare token anyway, and
both produced false negatives in `missing_phase_details`:

- The checklist scan built a token -> bracket-id Map, FIRST-WINS. Of two entries
  sharing a token, whichever the author wrote first classified both. With
  `- [ ] **[GSD.999] 01: Icebox**` above `- [ ] **[GSD.02] 01: ...**` the real
  phase inherited the icebox's sentinel verdict and vanished from the report;
  swapping the two bullets — same document, same phases — reported it. Pinned
  with a test asserting BOTH orders.

- The detail set was `new Set(phases.map(p => p.number))`, also token-keyed, so
  `[GSD.02] 01`'s heading marked token `01` present and satisfied
  `[GSD.03] 01`, which has no heading anywhere. Order-independent, same class.

Both sides now key on an occurrence key: the owner's `bracketQualifiedKey`
(fold- and padding-insensitive, so `[gsd.2] 01` and `[GSD.02] 01` are one
phase), falling back to a fold-normalized composite for the two shapes that
grammar refuses — a token carrying its own hyphen, which splices to an id whose
trailing segment the qualified-key grammar truncates (the hazard
`getMilestonePhaseFilter` guards with its own `!token.includes('-')`), and any
id it does not accept. With no bracket id the key IS the bare token, so the
legacy path keeps its exact keys and dedupe order.

The emitted value is unchanged — `missing_phase_details` stays an array of bare
tokens, matching `phases[].number`. Only the classification moved to the
qualified key, so two brackets' `01` both missing report `01` once instead of
one silently covering for the other.

* test(#2761): replace the two wall-clock ReDoS assertions with algorithmic bounds

Both guards asserted elapsed wall-clock time — `Date.now()` against a 20s
ceiling in the coherence suite, `process.hrtime.bigint()` against 1s in the
read-tolerance suite. Those measure the host machine rather than the SUT and
flake on a loaded CI runner (RULESET.TESTS.no-timing-assertion). Per
RULESET.TESTS.delete-bad-tests they are REPLACED, not skipped, and the
behavioral property each one guarded is preserved.

The property is "the widened bracket patterns do not backtrack
catastrophically", which is a claim about growth, so it is now stated by
scaling the input instead of by timing it:

- validate health runs the pathological unclosed bracket at 4,000 and 16,000
  characters and must return the same correct result (no W021) at both.
- The four reader entry points run five ReDoS shapes at 5,000 and 20,000 and
  must name exactly the phases each shape should name at each size, with the
  variant cardinality unchanged across the two.

Catastrophic backtracking is superlinear, so a regression cannot complete the
4x leg under any ceiling, while a bounded matcher is indifferent to the
scaling. The one attack that is well-formed-but-oversized now pins its reading
precisely (`['1'.repeat(n)]`) rather than being lumped in with the malformed
ones. A positive control asserts the readers still extract a well-formed
bracket heading, so "names no phase" cannot pass by the readers being inert.

`{ timeout }` is a hang backstop, not an assertion: it turns a runaway into a
deterministic failure instead of a suite that never returns.

* fix(#2761): give the bracket grammar one owner and teach the drift guard to see it

The bracket milestone-intro grammar was re-typed verbatim in three readers —
roadmap-parser's bracket-fallback selector, state's `isMilestoneBounded` and
verify's `checkBracketCoherence` — which is exactly what #2761's own gate
forbids ("no token literal outside src/phase-id.cts"). `check:phase-id-drift`
reported clean the whole time: its detector only ever knew the phase-NUMBER
token grammar, so the bracket class `[A-Z][A-Z0-9_]*` was invisible to it.

Ownership. `src/phase-id.cts` now exports the class as
`BRACKET_PROJECT_CODE_SRC` and the intro in the two shapes its readers need:
`bracketMilestoneIntroSrcFor(milestone)` (pinned to one milestone) and
`BRACKET_MILESTONE_INTRO_CAPTURING_SRC` (milestone captured). The pinned
builder owns the pad2 spelling rule too — "canonical spelling only, not `0*N`"
was previously restated in prose beside each copy, a convention two files had
to keep agreeing on by hand. `BRACKET_ID_SRC`, `BRACKET_ID_PREFIX_RE` and
`BRACKET_QUALIFIED_KEY_RE` now compose the class rather than re-spelling it.
All three call sites consume the owner; the regex sources are byte-identical to
what they spelled, asserted against hand transcriptions of the pre-fix lines.

Guard. `scripts/lint-phase-id-drift.cjs` gains a bracket rule
(`findBracketGrammarDrift`), wired into `scanRepo` and tagged `kind`. It
deliberately does NOT copy the token rule's `line.includes(CANON_REF)` escape:
that escape is line-level, and verify's copy referenced the owner for the
MILESTONE field on the same line as the re-typed PROJECT-CODE class — so a
bracket rule with that escape would have kept passing on the very site under
review. Partial ownership is the drift; only a dedicated `// phase-id-owner:`
comment suppresses it.

Proof, end to end: planting the shipped verify.cts literal back into src/ makes
`npm run check:phase-id-drift` exit 1 naming `[bracket] src/verify.cts:1475`;
restoring it returns the gate to ok.

Tests. phase-id-drift-guard carries all three shipped literals as negative
fixtures, the same-line-owner-reference case, the case-widened evasion variant,
the sanction rules, and a temp-tree scan proving the rule is wired into
scanRepo rather than merely exported. continuation-grammar-parity drives the
pinned and capturing shapes over a 12-entry corpus and requires the same
verdict from both plus the same captured milestone — widening either alone
fails there.

* test(#2761): drop the out-of-scope source-grep exemption from the selector pin

The baseline-selector pin in tests/adr-612-bracket-heading-selection.test.cjs
read `src/*.cts` with readFileSync and regex, claiming the no-source-grep
escape with a source-text-is-the-product reason. CONTEXT.md's documented scope
(RULESET.TESTS.no-source-grep.exemption) reserves that escape for tests whose
subject is a runtime CONTRACT FILE — STATE.md, config.toml, hooks.json, agent
.md — and `src/*.cts` is none of those.

It was also broader than it looked: eslint-rules/no-source-grep.cjs matches the
marker in ANY comment in the file, so one block's claim disarmed the rule for
the whole ~700-line suite.

The pin itself is worth keeping — the BASELINE ARGUMENT at each call site is a
fact no behavioural test can recover (flipping verify's milestone-complete site
from LABEL_ONLY to ANY_BRACKET grants a tolerance it has never had, and every
behavioural test still passes), so pinning it does require reading the authored
source. That reading moved to `scripts/lint-phase-id-drift.cjs` — the seam's
own guard, where source scanning is sanctioned (`warn` scope) and already
happens for the grammar rules — as `countSelectorBaselines` /
`scanSelectorBaselines`, which return a structured census. The test asserts on
the returned data and touches no file text.

CONTEXT.md is unchanged: the exemption scope was not widened to fit the test.
No marker remains in the suite, so the rule is live across all of it again, and
eslint passes with the escape removed rather than relocated. A floor assertion
pins that the census actually found the five consumers, so the "no other file
consumes the selector unpinned" check cannot pass on an empty scan.

* docs(#2761): rewrite the changeset as a lead + deltas instead of one paragraph

The fragment was a single ~6,400-character paragraph that opened on internal
mechanics, buried the user-visible change, and named an internal test path
(tests/adr-612-bracket-phase-counting.test.cjs) that means nothing to a reader
of the CHANGELOG.

It now leads with what a user sees — bracket-style phase IDs are recognized on
the read path across roadmap, validate, verify and state — followed by compact
bullets for the behavioral deltas, the opt-in caveat, and the upstream
consequences. Both merge-added disclosures are kept: the #3185 legacy-sentinel
Phase-0 delta with the reason the bracket counter keeps the narrower rule, and
the enumerator's convention-argument default flip with the four newly-scoped
read surfaces and the note that archival and milestone-completion paths are
unchanged. Two deltas from this review round are stated as their own bullets:
per-occurrence classification in `missing_phase_details`, and workstream-scoped
convention resolution including the workstream-rollup count change.

The internal test path is gone and the body is down to ~3,850 characters. The
bullets render as sub-bullets under the CHANGELOG entry and the `(#NNNN)`
suffix still lands on a trailing paragraph rather than mid-list.
`npm run lint:changeset` passes.

* test(#2761): use helpers.cleanup in the drift-guard temp-tree test

`local/no-raw-rmsync-in-tests` rejects a bare `fs.rmSync` in tests — the shared
helper carries the Windows-EBUSY retry budget. The temp-tree scan added with
M3's guard coverage test used the raw call.

* docs(#2761): correct the occurrenceKey comment on qualified-key normalization

The comment claimed `bracketQualifiedKey` is "fold- and padding-insensitive, so
`[gsd.2] 01` and `[GSD.02] 01` are one phase". The fold half is right; the
padding half is not. `BRACKET_MILESTONE_NUMERIC_SRC` is `(?:[1-9]\d{2,}|\d{2})`,
so `bracketQualifiedKey('GSD.2-01', 'bracket')` returns null and that input
takes the composite fallback instead.

No behavior change — the two key spaces use different separators and cannot
collide — but the claim was checkable and wrong. Restated: the owner case-folds,
and padding-tolerance is not a property it has or needs, because each accepted
milestone has exactly one canonical spelling and `[GSD.2]` is malformed rather
than an alternate spelling of `[GSD.02]`.

* ci(#2761): give the coverage-gate job the heap floor the shard jobs already have

The gate's report steps parse ~2.5GB of merged raw V8 dumps in one
process at the runner's implicit ~4GB ceiling, so pass/fail comes down
to GC timing (run 31338081337 OOM'd; next passes the same volume at
28s). Deterministic locally: crashes at --max-old-space-size=4096,
completes in 11s at 8192. PR shard data is within 0.15% of green next
runs — the load is pre-existing, only the ceiling was missing. #2952
set 6144 on the shard-collection step; the gate job was missed.

* Revert "ci(#2761): give the coverage-gate job the heap floor the shard jobs already have"

This reverts commit 03c74a97c911e9ddc53675aded9c9bbb89f14cd1.

* fix(#2761): thread the resolved convention into cmdStateValidate's phase-directory lookup

#3208 replaced cmdStateValidate's `startsWith` prefix test with the canonical
`phaseKeyFromDir(...) === selectedPhaseKey` comparison. That is the right
surface, and it is why the lookup now needs the resolved `phase_id_convention`,
which the rewrite does not pass.

`phaseKeyFromDir` deliberately refuses to read a bracket directory without an
explicit signal (ADR-2121: a bracket dir is string-indistinguishable from the
legacy letter-prefixed-decimal family), so un-threaded it returns the whole dir
name as the key — `GSD.02-05-real-work` -> `GSD.02-5-REAL-WORK` — while the
STATE side is the bare `05` that `parsePhaseFromProse` yields. Both sides of one
comparison derived under different conventions is #2562's defect class, and this
file's other three `phaseKeyFromDir` call sites already thread against it.

Observable: a bracket repo whose phase directory plainly exists reported
`valid: false` and "no phase directory matches phase 05", and the drift scan
(plan-count mismatch, verification status) never ran. The pre-#3208 `startsWith`
missed the same directory but skipped silently, so this is a visible-failure
regression on bracket repos, not a new miss.

Non-bracket conventions are byte-identical by construction: `extractPhaseToken`
branches only on `=== 'bracket'`, so null / 'milestone-prefixed' / unresolvable
compile the same path as the un-threaded call. The flat-legacy twin assertion
pins that.

* docs(#2761): note the cmdStateValidate convention threading in the changeset fragment

The fragment described the bracket read path as of the pre-merge branch. 504c64ff
added a shipped behaviour change — `state validate` now resolves bracket phase
directories — that the fragment did not mention, so the rendered changelog would
have under-described what ships.

* test(#2761): invert the inherited-wart characterization — #3225 fixed it upstream

Required by the merge of next @ 86101ee6; test-only, no src delta.

This branch disclosed rather than fixed a pre-existing upstream wart: on a
LEGACY repo, `### Phase 999:` warned from `validate consistency` while
`validate health` suppressed it — the two verbs contradicting each other.
The case was pinned as a characterization test ("INHERITED WART, unchanged")
precisely so it would INVERT if upstream ever closed it, rather than rot
silently.

ae7dc529 (#3225) closed it, by adding the `isSentinelPhaseId` guard to this
very loop. So the assertion inverted on the merge — as designed. Flipped to
assert the FIXED behaviour rather than deleted: it is the negative-space
proof that this branch's `sentinelPhases` guard never had to grow a legacy
reading of its own, and it reds if a future conflict resolution keeps our
guard while dropping upstream's.

Added a scope control alongside it (a legacy NON-sentinel `### Phase 09:`
with no directory still warns), so deleting the loop outright cannot pass.

Union proven load-bearing in BOTH directions against the merged tree —
neither guard subsumes the other:
  - drop `isSentinelPhaseId(p)` (ours only) -> 1 red, exactly this case.
    Note upstream's own #3225 tests stay GREEN there: they cover the
    disk-side loops (sentinel dir on disk) and the gap-numbering filter,
    not the ROADMAP-side loop. This case is that site's only coverage,
    which is the second reason to keep it rather than delete it.
  - drop `sentinelPhases.has(p)` (upstream only) -> 4 red bracket suites
    (icebox-not-missing, health/consistency agreement, occurrence-aware
    suppression, checklist-index suppression).

tests/adr-612-bracket-read-tolerance.test.cjs 79 -> 80, all green.

* test(#2761): pin the three re-homed W006/W007 reads the merge left unfalsifiable

#3309/#3310 deleted the helpers this PR threaded (collectDiskPhases,
collectDiskPhaseEntries, collectArchivedPhaseDirNames,
forEachArchivedPhaseToken) and rebuilt their reads inside
src/planning-snapshot.cts + src/health-diagnostic-rules/*.cts. The convention
threading moved with them in the merge commit — but a mutation sweep over the
re-homed sites found three where reverting the convention argument changed real
CLI output and NOT ONE existing test went red. The pre-migration sites were
covered indirectly, through helpers that no longer exist, so the coverage did
not survive the relocation even though the behaviour did.

Each case is pinned at the CLI with its flat-legacy twin as the byte-identity
control, plus a non-vacuity control in the opposite direction:

  archivedPhaseTokens      revert -> "Phase 05 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for a phase whose only directory is
                                     under .planning/milestones/v1.0-phases/
  roadmapPhaseCheckboxes   revert -> "Phase 09 in ROADMAP.md but no directory on
  (planning-snapshot.cts)            disk" for an unstarted `- [ ]` phase
  W007's extractPhaseToken revert -> "Phase GSD.02-77-orphan exists on disk"
  (roadmap-disk-consistency)         instead of "Phase 77 exists on disk"

Red/green: each single-line revert reds exactly its own case and nothing else;
every legacy control stays green in all three runs.

NOT pinned, and disclosed as droppable rather than given an unfalsifiable test:
buildValidPhaseSet's extractPhaseToken(dir, convention) in W002. That rule
unions disk tokens with roadmapDeclaredPhases and archivedPhaseTokens, and any
STATE.md reference a bracket disk token would rescue is already rescued by the
ROADMAP half — probed directly, the argument makes no observable difference. It
is threaded because it restores collectDiskPhases(planBase, convention)'s
derivation exactly, not because a test needs it.

Test-only; revertable independently of the merge commit.

* test(#2761): pin the two reads the #3165 extraction left unfalsifiable

DROPPABLE, offered as such. Test-only; the merge commit is correct without it.

#3428's extraction gave `collectAnalyzePhases` TWO call sites — the scoped
milestone window and the truncated-window recovery path. The merge threads
`convention` into both and swaps `detailKeys` with `phases` across the recovery.
Neither of those was falsifiable by the suite as it stood:

  - passing a NULL convention at the FALLBACK site, with the scoped site still
    threaded, is green across all 518 tests of the bracket, roadmap and
    milestone-window files. Every pre-existing bracket assertion reaches the
    enrichment through the scoped window, so none of them can observe the
    fallback's reading at all;
  - dropping `detailKeys = fallbackScan.detailKeys;` — the line this merge
    authored — is likewise green, because no fixture that reaches the recovery
    path carries a checklist bullet, so `missing_phase_details` is `null`
    either way.

That is the same hole class lap 3 closed in 9914359c: an argument whose revert
changes real CLI output with zero reds.

Pinned at the CLI on the shape that reaches the fallback on a bracket repo — a
MID-MIGRATION ROADMAP: bracketed ACTIVE milestone, its phase-detail sections
and checklist bullets sitting after an intervening CLOSED legacy milestone (so
the window closes over prose only), plus one legacy `### Phase N:` section of
its own. Six tests:

  - a NON-VACUITY control that removes the phase directories, so #3428's own
    precondition fails and the result is the empty one the recovery exists to
    replace — this is what proves the rest read the FALLBACK's output rather
    than the scoped scan's;
  - the directory assertion (`disk_status`/`plan_count`/`summary_count` for
    canonical `{CODE}.{MM}-{PP}-slug` dirs) + a flat-legacy twin asserting
    byte-equal shape, and that the twin is the right answer rather than a
    shared wrong one;
  - `missing_phase_details: null` for phases the recovery just found, and its
    companion direction — a bullet with no heading anywhere is STILL reported,
    so a fix that merely suppressed the report does not pass;
  - a non-bracket repo taking the same path unaffected.

Red/green, each mutation reverted afterwards:
  - fallback call site -> `null` convention: exactly 2 reds, both directory
    assertions in this block; 307 other tests green, including upstream's own
    #3428 tests in tests/milestone-window-single-owner.test.cjs.
  - `detailKeys` swap deleted: exactly 2 reds, both `missing_phase_details`
    assertions; 414 other tests green.
  - `matchPhaseDirs` 3rd argument dropped (the lap-2 site): 4 reds — the 2
    already on record plus this block's 2, which is the point: one seam, now
    reached by two paths.

DISCLOSED IN THE TEST BODY WITH MEASURED OUTPUT, not fixed: `hasPhaseEntries`
(src/roadmap-parser.cts) is convention-blind, so on a PURE-bracket ROADMAP the
window classifies COMPLETE and #3428's recovery is gated off entirely. That
document returns `{"scope":"complete","phase_count":0,"next_phase":null,
"phases":[]}` — the "genuinely empty milestone" answer, the indistinguishability
#3184 introduced `scope` to remove — where the flat-legacy twin returns
`{"scope":"truncated","phase_count":2,...}`. Widening it changes the value of an
upstream-owned output field on bracket repos, so it is a behaviour slice (the
PR-2.5/PR-4 convention-less-readers question), not a merge-round change. The
mid-migration shape pinned here is the reachable half.

* fix(#2761): mirror the bracket terminator in the milestone-scope write guard

parser's terminator vocabulary — "a level 1-3 heading that is not a Phase
heading and carries a milestone signal". On this branch that vocabulary is
convention-SELECTED: `computeBracketSectionEnd` adds `isBracketMilestoneBoundary`
as a terminator arm, and the ADR-canonical `## [GSD.09] Hidden` carries NO
vN.N token, NO ✅/📋/🚧/🔄 marker, and not the word "Milestone". Left
unmirrored, the guard accepted exactly the description it exists to reject.

NOT a defect on clean next — a bracket heading terminates nothing there. The
branch widens the terminator set, so the branch owns the mirror.

MEASURED at the CLI seam before the fix (bracket fixture, one milestone,
one phase):

  $ gsd-tools phase add $'Sneaky\n## [GSD.09] Hidden'   -> exit 0, written
  $ gsd-tools phase add 'Innocent follow up'            -> exit 0, written
  $ gsd-tools roadmap milestone-scope
    { "scope": "complete", "phases": ["01","1"], "phase_count": 2 }
  $ grep '^### Phase' .planning/ROADMAP.md
    ### Phase 1: Sneaky
    ### Phase 2: Innocent follow up      <- in the document, out of the window

After the fix the first add exits 1, ROADMAP.md is byte-unchanged and no
phase directory is created. The legacy twin (same text, no
`phase_id_convention`) still exits 0 — opt-in only, base behaviour preserved.

SHAPE
- `findMilestoneScopeHeadingLines(text, convention)` — REQUIRED, the same
  tripwire `scanMilestonePhaseIds` carries in the merge commit and for the
  sharper reason: a blind call here fails OPEN (the guard quietly ACCEPTS a
  window-narrowing description), so a future call site must fail to COMPILE.
  Census is one caller, which pays nothing for it. A non-bracket value takes
  the pre-existing path byte-identically. The bracket arm routes through
  `isBracketMilestoneBoundary`, the same single-owner phase-vs-milestone
  discriminator `computeBracketSectionEnd` consults; no second bracket-heading
  grammar is spelled here.
- `selectedBracketId` is deliberately `null`, so the same-milestone
  CONTINUATION exemption never fires and a value naming the ACTIVE milestone
  is flagged too. That is this predicate's third stated conservatism and
  rests on its own existing argument: which milestone is active is a property
  of the document at write time, not of the text being validated, and
  over-rejecting is one-directional.
- `assertDescriptionPreservesMilestoneScope` takes `cwd` and resolves through
  the branch's tolerant try/catch — this guard runs BEFORE `loadConfig` and
  before the ROADMAP existence check, so an unresolvable convention must
  degrade to the legacy vocabulary, never turn a rejection into a crash.
- The error's marker list gains the bracket form only when the project is on
  the bracket convention.

RED/GREEN
- Revert the bracket arm -> 2 reds (phase add; insert + add-batch), the
  non-bracket control and both no-false-positive cases stay green.
- Revert the probe threading in the merge commit -> 1 red (the probe case).
- 6 new cases in the #3262 file, each with a non-bracket or
  no-false-positive control: fenced bracket milestone heading and bracket
  PHASE heading are both non-violations.

Droppable: revert this commit and the merge stands on its own; the branch
then ships the gap as a disclosure instead of a fix.

* docs(changeset): narrow the enumerator claim to the directory set — per-entry rendering in progress/stats/init-manager is display-slice scope

Round-7 review confirmed 3 of the 4 surfaces named by the closing claim
parse each directory or heading with legacy-only patterns that live in
files this PR does not touch (commands.cts:1766, commands.cts:2116,
init.cts:2241). The claim now states exactly what this slice delivers:
the scoped directory set. Their per-entry conversion is display work,
deferred to the epic's display PR with the statusline/progress-card
gates it belongs beside.

* fix(#2761): de-accident the unmatched-milestone bracket fixture, re-pin to #3480's withhold contract

tests/adr-612-bracket-phase-counting.test.cjs:515 ("a milestone that
does NOT match STATE is not scoped in") asserted total_phases === 0.
Since today's merge brought in 70b5c1a1 (#3354/#3480, already in
`next`), buildStateFrontmatter withholds total_phases (omits the key,
read back as null) for a milestone that is genuinely sectioned but
matches no ROADMAP heading, instead of substituting a computed number
— the fixture's `state json` read now returns null, failing the
strictEqual(0) assertion.

The original single-section fixture's 0 only ever survived by
accident: hasMilestoneSectioning requires >=2 milestone-vocabulary
headings to call a ROADMAP sectioned, and its isPhaseHeading helper
recognizes only the legacy `Phase N:` text form — so the bracket
phase heading `### [GSD.03] 09: Not this milestone` (title containing
the word "milestone") miscounted as a second milestone heading,
tipping hasMilestoneSectioning true and routing to the disk-count
branch. With that miscount removed, the same one-section fixture
reads 1 (the non-matching milestone's phase count leaking into v2.0's
total) — proving the pinned 0 was never validating the scoping this
test claims to exercise.

Replaced the fixture with two genuine milestone sections (GSD.03,
GSD.04), neither matching STATE's v2.0, with phase titles carrying no
incidental vocabulary — the real #3354 shape. Re-pinned the assertion
to null, matching upstream's own tested contract (tests/state-
document.test.cjs, "#3354 with nothing stored, the key is omitted
rather than written from the dir count").

Verified: file green 3/3 runs (104/104), full state-suite regression
771/771 green. The isPhaseHeading gap that made the old fixture
accidental is a real, pre-existing, upstream-owned limitation
(hasMilestoneSectioning only guards >=2-section conflation, not a
single non-matching section leaking through) — not introduced by

* chore(#2761): exempt two self-authored-fixture regexes from #3441's unbounded-quantifier rule

Both sites parse the STATE.md the test itself just wrote to its own
tmpdir — fixed-size fixture output, not adversarial or document-scale
input. Exempted with the justification-comment pattern the tree's own
tests use for this exact case (settings-integrations, copilot-install,
research-agent-profiles). The sites predate the rule; #3441 landed on
next this morning and this branch picked it up in the catch-up merge.

* fix(#2761): fix forward two next-movement test regressions from the round-11 rebase

origin/next's #3573 newly threads STATE's stored `milestone:` value into
`state json`'s buildStateFrontmatter call (previously always `undefined` on
that read surface). Two pre-existing PR-2 fixtures reach code paths that
call never exercised before that merge:

- RED (repro2 case C): a version-less, all-bracket-id ROADMAP now hits
  getMilestonePhaseFilter's pre-existing (unaffected by this branch) row-5
  `versionResolved && !headingFound => SCOPE.UNSCOPED` rule, which withholds
  `progress.percent` even though the scoped total_phases/completed_phases
  are still correct. That row-5 rule is load-bearing for six other
  version-less-document pins in this same file; narrowing it broke seven of
  them in testing, so production code is untouched here. Reassert the
  test's real claim (scoping, via total_phases/completed_phases) and
  disclose the now-withheld percent instead of silently dropping it.

- PIN (repro12 LEGACY control): a fenced-example-vs-real version heading
  fixture. #3573 routes this read through sliceMilestoneWindow (fence-aware)
  instead of the legacy anyMilestonePattern raw scan (fence-blind) this pin
  was disclosing as out of scope, so the fixture no longer exercises the
  blind path — total_phases moves from the whole-doc 4 to the correctly
  scoped 2. Re-pinned with an upstream-attributed comment, matching this
  file's existing house style for prior origin/next movements (see the
  sibling "PIN (G3 LEGACY control)" comment).

Both are test-only fix-forwards: no production code changed. The remaining
12 failures in this file at 27363e9d0 (dropped seam commits' VERIFICATION.md
naming + fixture updates) are pre-existing and deferred to the stacked
follow-up per the task's own scope.

* fix(#2761): thread phaseIdConvention explicitly at the two write-adjacent enumerator call sites (round-11 BLOCKER)

listMilestonePhaseDirs' phaseIdConvention param lost its `= null` default
(phase-locator.cts), so an omitted convention now means "resolve from
config" instead of "explicitly not bracket" — a deliberate flip, but
milestone.cts and state.cts were not in the PR-2 diff and both call the
enumerator without threading it:

- milestone.cts cmdMilestoneComplete (the single #3597 shared derivation
  feeding the stats loop, --dry-run preview, and the real archive/rename
  pass) now resolves phase_id_convention once and threads it explicitly,
  so a bracket project's `milestone complete` archives its real
  bracket-declared phase directories instead of silently inheriting
  whatever the enumerator's lazy default resolves to.
- state.cts cmdStateUpdateProgress's own enumerator call threads the same
  resolved convention. Empirically this does not change the #3217 withhold
  gate (scope is assigned before headingConvention resolves in
  getMilestonePhaseFilter, so it's convention-independent either way) or
  the reported percent (already correctly threaded via
  computeUpdateProgressPreview -> buildStateFrontmatter); it closes a
  second, silently-resolved answer to the same question this file's own
  ONCE-and-THREAD rule (~:2300) already states as policy.
- state.cts's other listMilestonePhaseDirs call site (the state-sync
  scope-only read, ~:4791) is left unthreaded on purpose, with an inline
  note explaining why: only `.scope` is consumed, and `.scope` is set
  before convention resolution in getMilestonePhaseFilter, so it cannot
  disagree with a threaded convention.

Both enumerated sets are pinned by new tests (round-11 BLOCKER block in
tests/adr-612-bracket-phase-counting.test.cjs), including a mutation-style
regression check on the milestone.cts fix (forcing the un-threaded default
back on makes the pinned test fail, catching a regression to the
pass-all-degrade legacy reading).

* fix(#2761): correct the changeset's false archival claim and amend ADR-612 for the round-11 M2(2) split scope

The changeset (.changeset/2761-bracket-read-tolerance.md) asserted "The
archival and milestone-completion paths are unchanged" — false: both
paths reach the widened enumerator, and this PR now threads their
convention explicitly (previous commit). Replaced the closing paragraph
with an accurate description of what changes for a bracket project at
those two call sites, and notes both enumerated sets are pinned by tests.

ADR-612 (docs/adr/612-bracket-phase-id-convention.md) amended per M2(2):
the 2026-08-03 PR-2/PR-4 boundary proposal is added in-body (PROPOSED,
not stamped — mechanics per docs/contributor-standards.md:143 reserve ADR
ratification to maintainers), rescoped to what actually ships in PR-2
(#2761) now that the round-11 M1 split moved the completion-seam
threading (isPhaseArtifact/scopeToPhase, phase-id.cts:964-1090) out into
a separate, stacked follow-up PR referenced generically via epic #612:

- state.cts read-tolerance (both total_phases derivations, the #1514
  retirement filter) moves into PR-2's row, alongside milestone.cts,
  reflecting the round-11 fix above.
- the write-observability point is restated in terms of what actually
  ships: explicit threading at two named call sites, pinned by tests,
  rather than silent inheritance.
- the completion-seam threading is named and explicitly excluded from
  PR-2's scope, with a new ratify item (5) and a Negative consequence
  bullet covering the sequencing cost.

* fix(#2761): repair round-11 response gaps — disk-side sentinel bug, test-fixture bug, scanMilestonePhaseIds caller drift

Four independently-verified gaps in the round-11 repair response:

1. isSentinelPhaseId (src/phase-id.cts) treated a bare, untagged phase
   directory under phase_id_convention: "bracket" (`0-bootstrap`, no
   `{CODE}.{MM}-` prefix) as sentinel milestone 0 by falling through to the
   legacy leading-int rule when the bracket-tag match failed. This silently
   dropped a real, on-disk, milestone-declared phase directory from
   `listMilestonePhaseDirs` (phase-locator.cts:424, the only unguarded call
   site) and undercounted completed_phases/percent. Mirrors the carve-out
   already present on both heading-side counters (state.cts's
   countRoadmapPhaseHeadings guards its bare-0 exclusion with `bracketId &&`;
   roadmap-parser.cts's scanMilestonePhaseIds composes the bare-token rule as
   999-only) — under bracket convention, milestone 0 is expressed only via an
   explicit bracket tag, so an untagged leading 0 is a real phase token.

2. tests/adr-612-bracket-phase-counting.test.cjs's writeProject fixture
   hardcoded `01-VERIFICATION.md` for every "complete" phase dir regardless
   of the dir's real phase token. Under legacy convention this file already
   correctly failed #3511's strict isPhaseArtifact match for any dir other
   than phase 01 (the fixture never modeled what it claimed to); under
   bracket convention the pre-existing ambiguity fail-safe admitted it
   regardless. The two readings' disagreement was mistaken for a missing
   completion-seam threading (isPhaseArtifact/scopeToPhase convention
   awareness, correctly split out to the stacked #3644 per round-11's M1).
   Replaced the hardcoded name with verificationNameFor(dir), deriving the
   real per-phase filename from the production normalizePhaseName the same
   way cmdScaffold does — the 7 failing "flat-legacy-twin" / CHARACTERIZATION
   assertions pass on #2867's own code with no seam threading required, and
   the genuine seam-dependent cross-phase-stray-exclusion test the fixture
   fix would otherwise have hidden lives on the stacked branch instead.

3. tests/roadmap-parser.test.cjs's two #3577 tests still called
   scanMilestonePhaseIds with the old single-Set return shape; this PR
   changed it to `{ ids, qualifiedIds }` for every other caller but missed
   these two, which don't touch #2761/bracket code at all. TypeErrors at
   runtime, not silently-wrong assertions. Updated both call sites.

4. .changeset/2761-bracket-read-tolerance.md gains a paragraph disclosing
   fix 1 above, so the changeset stays accurate to what actually ships (the
   round-11 BLOCKER was exactly this changeset going stale once).

Verified: tests/adr-612-bracket-phase-counting.test.cjs +
tests/continuation-grammar-parity.test.cjs + tests/roadmap-parser.test.cjs =
354/354. adr-612-{coherence,grammar,heading-selection,read-tolerance,
selection.property}.test.cjs + collision-characterization = 287/287
(CONFIRMED-CLEAN set, unaffected). Full unfiltered suite run separately.

PR #3643 (round-11's M1 split, opened draft per that round's explicit
requirement) was auto-closed by this repo's own draft-PR policy 11 seconds
after opening — draft PRs are unconditionally closed here. Reopened as
non-draft #3644 (same branch, same commits, DO NOT MERGE / stacked-on-#2867
marker in the body, enhancement template) since the repo's own bot confirms
non-draft contributor PRs are tolerated even off-template.

* fix(#2761): narrow the state-update-progress pin claim to what mutation testing actually proved, add the test that covers the rest

Round-11 BLOCKER response gap (verified, not a guess): the changeset and
ADR-612 amendment point 2 both claimed the round-11 tests pin
`cmdStateUpdateProgress` so "a future change to the enumerator's default
cannot silently move ... what state update-progress reports without failing
a test." Mutation testing disproves this. Reverting BOTH the state.cts
explicit `phaseIdConvention` thread AND simulating the phase-locator.cts
pre-#612 hardcoded-null default (`phaseIdConvention: null` at that one call
site) leaves the existing PIN test ("writes a real percent for a
bracket-scoped milestone") green, because that percent comes from
`computeUpdateProgressPreview` -> `buildStateFrontmatter`, a separately and
already-correctly-threaded derivation the state.cts inline comment at ~:965
already candidly documents.

What the reverted thread DOES change, empirically, is `phaseDirs`/`totalPlans`
— the enumerated `.value` this call site feeds into the #3233 zero-plans
no-op gate a few lines below. That is the one place a regression at this call
site is observable in the command's output. Added a test that pins exactly
that: a bracket milestone whose declared phases carry no plans on disk,
alongside a decoy directory that plainly does not belong to the milestone
(no bracket tag, no phase token) but does have a plan. Correctly scoped, the
decoy is excluded and the #3233 no-op fires (`updated: false`). Degraded to
the pass-all legacy reading, the decoy is swept in, `totalPlans` flips
nonzero, and the no-op never fires (`updated: true`).

Mutation-tested against both scenarios:
- Reverting ONLY the state.cts explicit thread (falls back to `undefined`,
  which `getMilestonePhaseFilter` resolves via the identical
  `resolvePhaseIdConvention(cwd, undefined)` call the explicit thread also
  makes): new test stays green — confirms the single-hunk thread really is
  pure single-derivation hygiene, exactly as the existing inline comment
  claims, for this test too.
- Forcing `phaseIdConvention: null` at that call site (the combined-revert
  scenario the round-11 mutation testing actually exercised): new test FAILS
  (`updated: true, percent: 0` instead of the expected `updated: false`).
  Restoring the real code makes it pass again.

Narrowed the changeset and ADR-612 point 2 prose to match: `cmdMilestoneComplete`'s
enumerated set is pinned against a pass-all-degrade regression (genuine,
already verified in round 11); `cmdStateUpdateProgress`'s own call site is now
pinned against the #3233 zero-plans no-op specifically, not against the
reported percent, which the prose no longer claims. Added a one-line pointer
to the new test in the state.cts inline comment. No production behavior
changes — test and documentation only.

* docs(#2761): reconcile ADR PR-2 module map

* fix(#2761): restore #3639's dir-aware W007 sentinel exclusion lost in the rebase replay

The rebase replayed this file's pre-#3639 patch over next, reverting the
isSentinelPhaseId(token) -> isSentinelPhaseDir(dirName) fix: the extracted
token is milestone-stripped, so a bracket sentinel (GSD.999-07-icebox,
GSD.00-01-backlog) was invisible to the id predicate and false-fired W007.
Restores upstream's call and comment verbatim; the branch's convention-aware
token remains for the diagnostic message only.

Caught by next's own #3639 regression tests (CI shard 2). Local: the file's
18/18, health-diagnostic-rules 165/165, full npm test exit 0.

* docs(#2761): ratify scope and correct surface claims

* test(#2761): strengthen legacy selection and drift claims

* docs(#2761): correct the enumerator claim, scope list, and ratification receipt

Three documentation corrections, none touching production code.

The changeset claimed the shared phase-directory enumerator "now defaults its
convention argument to 'not yet resolved' rather than 'resolved, and not
bracket'". That is false: `phase-locator.cts:375` still destructures
`phaseIdConvention = null`, and the lazy resolve-from-config fires only on
`undefined` (`roadmap-parser.cts:941`, `:1928` — whose own comment records that
"explicit null still means 'resolved and non-bracket'"). Measured: only 4 of 17
`listMilestonePhaseDirs` call sites thread a resolved convention (`milestone
complete` and `state`'s three). The changeset went on to name `progress`,
`stats`, `phase list` and the init manager view as now receiving a correctly
scoped set — those are precisely callers that omit it. Replaced with what the
code does, and the deferral stated plainly.

The ADR's PR-2 row omitted `scripts/lint-phase-id-drift.cjs` (+141/-14) and
`scripts/lint-phase-enumeration-drift.cjs`, both changed by this PR. An
under-claim rather than an over-claim, but the row is the epic's
scope-of-record.

Ratify item 5 asserted maintainer ratification while citing only the review that
raised the question. It now cites the review that granted it (#2867 review
`5012940978`, 2026-08-24) and quotes its terms, so the claim carries its receipt.

Found by an adversarial review pass over the round-12 diff. (#2761)

* fix(#2761): drop the no-op --json that strict argv now rejects

Surfaced by the rebase onto next, not by a change in this PR's subject.

#3884 ("failure is a value — strict argv", e20744eac) made an unrecognized
flag a hard error: `state validate --json` now exits 1 with
`unknown flag "--json"; accepted: --strict` on stderr and EMPTY stdout,
where the token was previously accepted and ignored. `state validate` never
had a `--json` flag — JSON is its only output shape — so the argument was a
silent no-op from the start.

The helper parsed that empty stdout, so all five subtests in the
"state validate resolves bracket phase DIRECTORIES" suite failed identically
with `SyntaxError: Unexpected end of JSON input` at the JSON.parse, masking
what they actually assert.

Dropping the token restores the same envelope the helper already parsed. No
assertion changes. Verified against the fixture the suite builds: exit 0, and
the output carries the S005 plan-count warning the drift assertions require
with no S004 phase-directory warning — i.e. the bracket directory resolves,
which is the behaviour these tests exist to pin. 94/94 in the file.

* fix(#2761): exempt the phase-counting suite from the docs-guard lane

Surfaced by the rebase onto next. #3753 (107eb8c1d) added
lint-docs-guard-registration, which requires every test file that reads a
docs/ path to be either registered in the docs-guard lane or carry an
explicit marker. It flags adr-612-bracket-phase-counting.test.cjs, which
reads no docs/ path at all.

The file's only docs/ occurrence is the ADR-612 Decision 1 citation in a line
comment; every read call it makes targets a tmpdir .planning fixture. It trips
Detector 3, whose DOCS_TEMPLATE_LITERAL_RE sees an odd prose backtick in the
comment block above that citation as opening a template literal and reads the
span between them — citation included — as a docs/ path expression. That
detector documents this trade in its own header: it favours recall, and says a
false positive costs one docs-guard-exempt marker with a reason. The baseline
records the same class ("comment-only mentions") for 46 of its entries.

Registration was the wrong side of the trade here: it would run this suite in
the docs-guard lane on docs/ changes whose content it never reads.

Three pieces, matching what the gate requires and what its 54 existing entries
already do:
  - the marker in the file's header window, written without backticks so it
    cannot itself disturb the parity tracking findExemption does;
  - the basename in DOCS_GUARD_EXEMPT_BASELINE, since the ratchet fails a new
    marker until the baseline is deliberately updated — the reviewable diff is
    the point;
  - the FIX 3 per-file fingerprint, derived with the lint's own
    extractDocsPathReferences rather than retyped, so the exemption fails loudly
    if the set of docs/ paths this file mentions ever changes.

Gates: lint-docs-guard-registration 0 violations, ci-docs-guard-registry 51/51.

* docs(#2761): correct the bare-0 comment and state what opting into bracket costs

Round-13 review items Minor 2 and Minor 3, both still live on the previous head.

Minor 2 — src/phase-id.cts. The comment block claimed "Bare `0` is admitted
alongside it because a 0.x sentinel is a legitimate identity that predates
padding", which contradicted both the shipped constant and its own next
paragraph. BRACKET_CANONICAL_NUMERIC_SOURCE is `(?:[1-9]\d{2,}|\d{2})`;
measured against it, `0` is rejected while `00`, `05`, `99`, `100` and `999`
are admitted. The paragraph four lines below already recorded the removal
("the earlier `(?:\d{2,}|0)` ... admitted ... a bare `0` that pad2 never
produces"), so the block asserted and denied the same fact. The stale sentence
is replaced with what ships: `00` is the backlog sentinel's canonical padded
identity, `\d{2}` already covers it, and nothing needs the unpadded spelling.
No behaviour change — the constant is untouched.

Minor 3 — docs/CONFIGURATION.md. The phase_id_convention row described the
read-path widening but never said what a repo GIVES UP by opting in. Added:
on a bracket repo a heading whose bracket is followed directly by a digit is
read as a phase heading, so `### [RFC.2119] 5:`, `### [v1.0] 2024:` and
`### [ADR.612] 3:` — legal prose headings under any other convention — are
claimed as phases and move phase_count, total_phases and W006. Those three
shapes are the ones phase-id.cts's own selector comment names as the reason
the widened read is selected at construction time from this value rather than
applied everywhere; the row now carries that trade instead of only its
upside.

Gates: tsc --noEmit exit 0, npm run lint:ci exit 0, npm run test:unit
33890/33891 with the single failure being emitted-attribution's base drift
against a next that moved after the rebase (133/133 against the rebase base;
this push re-bases onto the current tip, which resolves it).

472f585f7c fix(#3726)!: require --confirm before milestone complete mutates (#3774)
* fix(#3726): require --confirm before milestone complete mutates

`milestone complete <version>` is a one-way door — ROADMAP.md and
REQUIREMENTS.md archived, every phase directory in the milestone MOVED,
STATE.md rewritten — and ran unconditionally on first invocation through
every invocation path, including `query milestone.complete <version>`,
whose `query` meta-prefix reads as a read-only namespace but performs no
filtering (#167's invocation-compatibility shim + #3243's dotted-form
normalization).

The gate lives on the destructive command itself, not on the `query`
prefix (the prefix is an intentional invocation mechanism, not a
permission boundary — restricting it would break dozens of shipped
workflow callers). Without --confirm and without --dry-run the command
now refuses via error() before reading anything beyond its arg checks,
so an unconfirmed invocation is a guaranteed no-op on disk. --dry-run
still previews with no confirmation needed and is now documented in the
usage block (it was only documented for the sibling archive-quick).
--force keeps its narrow meaning — bypassing the TRUNCATED-scope and
unstarted-phase guards — and does not double as the mutation opt-in.
--confirm follows the existing `phases clear --confirm` idiom in the
same module.

complete-milestone.md's two invocations pass --confirm (the workflow has
gathered explicit user intent by that step). Existing tests get
--confirm appended — pre-change behavior is exactly confirmed behavior —
and a #3726 regression block covers: refusal + full-tree byte-identity
on both invocation forms, --force not satisfying the gate, --dry-run
still passing without confirmation, and --confirm proceeding. The
refusal tests fail against pre-fix code (negative control run).

Fixes #3726

* docs(#3726): document the --confirm requirement in CLI-TOOLS and COMMANDS

Cross-AI review of the fix diff (codex, pre-create) caught three shipped
doc sites still instructing the now-refused bare invocation: the
CLI-TOOLS.md milestone-complete synopsis + flag table, and COMMANDS.md's
two guard-override instructions (`--force` alone now refuses without
--confirm). Localized CLI-TOOLS copies already lag the English synopsis
(no --force/--dry-run either) and follow the translation pipeline, not
this fix.

* chore(#3726): set changeset fragment pr to 3774

* test(#3726): confirm-gate CI repairs — QA scenario caller + growth ack

Two CI reds from the --confirm gate, both this branch's own misses:

- tests/qa/scenarios/milestone-rollover.json invoked `milestone complete
  1.0 --force` as a JSON arg-array fixture — a caller shape the test
  sweep (which grepped runGsdTools/runSdkQuery in tests/*.cjs) never
  enumerated. Adds --confirm; the scenario's boundary-crossing contract
  is otherwise untouched.
- complete-milestone.md's +420-byte --confirm note trips the
  emitted-attribution growth ratchet. Acknowledged as a #3726 append to
  the existing complete-milestone.md entry in
  3409-unreachable-guard-arms.json (two ack sources may never name the
  same path, per that fragment's own precedent).

Local: lint-emitted-drift-ack ok; loop-walk.qa 115/115 green sandboxed.

* docs(#3726): CLI-TOOLS.md guard-override sentences say --force --confirm

Review Major 1: the truncated-window and unstarted-phase guard paragraphs
still told the reader to "Pass `--force` to override", which now refuses
(--force alone does not satisfy the confirmation gate), while the flag
table 470 lines later said the opposite. Mirror the docs/COMMANDS.md pair
so the file no longer contradicts itself.

* docs(#3726): synopsis renders --confirm and --dry-run as alternatives

Review Nit 1: `milestone complete <version> --confirm [--dry-run]` read as
"a dry run still needs --confirm", the opposite of AC 3. Render the pair
as `(--confirm | --dry-run)` in the CLI-TOOLS.md synopsis and the usage
docblock, and let the flag rows carry the rule.

* test(#3726): pass --confirm in base-added milestone fixtures; re-file the growth ack

Rebase onto next (26 commits) surfaced three tests the gate now refuses:
the #3685 write-flag contract pair in tests/milestone.test.cjs and the
`milestone complete` boundary fixture in tests/state-contract.test.cjs
all invoke the command bare. Each now passes --confirm (a mutating run is
exactly what they assert on).

The +420 byte complete-milestone.md growth ack rode on
3409-unreachable-guard-arms.json, which #3078 swept from next as fully
spent — hence the modify/delete conflict. Re-filed under a fresh fragment
named for this issue, never resurrecting the swept one.

* test(#3726): pin the present-but-falsy arm of the confirmation gate

Review Minor 1: the boundary triple covered absent and present but not
present-but-falsy. The gate is an exact-token match, so --confirm=false
and --confirm=0 refuse today — pinned (canonical + query forms, whole
.planning/ tree byte-identical) so a future `=`-aware or prefix-matching
parser cannot silently turn --confirm=false into a confirmed run of an
irreversible command.

* test(#3726): drop --confirm from dry-run-only invocations

Review Nit 2: --confirm was mass-appended to 14 pre-existing --dry-run
invocations that never needed it, so each stopped standing as incidental
proof that a preview needs no confirmation. Reverted to the pre-PR form;
the dedicated AC-3 test carries the explicit assertion.

* docs(#3726): sync the localized CLI-TOOLS synopsis with the confirm gate

REQ-I18N-02 (docs/features/internationalized-documentation.md) requires
translations to stay synchronized with the English source. The four
localized CLI-TOOLS.md guides still advertised a bare
`milestone complete <version>`, which now exits 1. Render the English
synopsis verbatim — `(--confirm | --dry-run)` plus the `[--force]` and
`[--archive-quick]` flags the translations had also fallen behind on.

* test(#3726): drop --confirm from the remaining preview-only invocations

Round 2 reverted the --confirm appends on --dry-run-only invocations in
tests/milestone.test.cjs, but four more sat in two files the sweep missed:
tests/milestone-archive.test.cjs (three) and
tests/milestone-window-single-owner.test.cjs (one).

Each is a preview run whose whole purpose is to document that a preview
mutates nothing, so `--dry-run ... --confirm` contradicted the semantics
the test exists to pin. Dropping the token restores each as incidental
proof that a preview needs no confirmation; the dedicated AC-3 test keeps
the explicit assertion.

No assertion added, relaxed, or removed — the change is four tokens.

* chore(#3726): migrate the emitted-drift ack from a fragment to a commit trailer

#3954 (ADR-3942) moved emitted-drift acknowledgments out of
tests/emitted-drift-acks/ and into git commit trailers, and the fragment
directory no longer exists on next. The reason this PR's fragment carried
moves verbatim into the Emitted-Drift-Ack-Growth trailer on this commit;
the fragment file is removed rather than resurrected.

Emitted-Drift-Ack-Growth: complete-milestone.md — #3726: +420 bytes (40186 -> 40606). The archive_milestone step's two `milestone complete` invocations now pass the required --confirm flag (the command refuses to mutate without it — the archive is irreversible), with a note explaining the flag and pointing at --dry-run for previews. Deliberate runtime-loaded workflow text for the new gate, not converter drift.

* fix(#3726): name --confirm in the version-required refusal

The documented arg-discovery path (gsd-tools.cjs top-level usage: invoke
the command without args and the error lists what is required) stopped at
`version required for milestone complete (e.g., v1.0)` — one required
argument short. Discovering --confirm took a second round trip through the
gate. The refusal now reads `… — and --confirm to mutate`, pinned by a test
that also asserts the version-less invocation leaves .planning/ untouched.

* test(#3726): pin the milestone complete docs against a silent regression

The changeset is `type: Fixed`, which the docs-required lint exempts, so
nothing in CI would notice a later edit that reinstated the bare-`--force`
override prose or dropped `--confirm` from the synopsis. Four tests in
tests/milestone.test.cjs now pin: the synopsis line in docs/CLI-TOOLS.md
and its four localized mirrors; the `--confirm` flag row; both
guard-override instructions in docs/CLI-TOOLS.md and docs/COMMANDS.md,
by guard name (a substring match on each instruction's `--force
--confirm` text); and — as an identity ratchet over the
milestone-complete sections — every `--force` sentence or clause that
lacks `--confirm`, so a new bare instruction in its own sentence or
clause fails whatever its wording. Named residual: a bare instruction
spliced into the same clause as a compliant one coalesces with it and
passes the ratchet; the by-name pins are what keep the four known
instructions from losing the pairing that way. The file is registered
in scripts/docs-guard-registry.cjs so the pin runs on the PR that
changes those docs, not only after merge.

d98b55562c enhance(#3910): the raw terminator is banned by construction (#3980)
* enhance(#3910): move the last src/ terminators onto the seam

Phase 6 bans the raw terminator by construction, which it cannot do while
violations stand. A census found 12 sites the rule would flag; nine of the ten
unsanctioned ones were owned by no phase of the epic at all — a coverage hole
in the decomposition, since P0-P2 are infra, P3 the gate modules, P4 the
scanners, P5 the fragments, P7 the hooks, P8 io.cts, and P6 itself only adds
the rule. `src/**/*.cts` now holds exactly 2 raw exits, both inside
`terminateNow`, the single sanctioned site.

`io.cts`'s `error()` is the interesting one. It was first called substantive on
"dozens of callers, contract risk" — asserted, not measured, and the
measurement refuted it: 289 call sites, zero inside a try whose catch would
swallow a throw. The real obstacle was structural instead: `terminateNow`
cannot emit exit 1, because ADR-3889 §1 makes 0 and 1 unallocatable and
`nameForExitCode(1)` throws. So the only route is `ExitError` under `runMain`,
which sets exitCode and writes stderr only when the error carries a user
message — keeping the existing stderr write and throwing a message-less
ExitError is observably identical.

That census was still too narrow, and running the CLI proved it. It asked
whether the CALL sits in a try/catch; the two regressions that surfaced were
interceptors elsewhere on the stack:

- `command-routing-hub.cts`'s `dispatch()` swallowed the ExitError into a
  HandlerFailure, so the caller emitted a duplicated, wrong stderr line on
  every Hub-routed path. It now rethrows ExitError explicitly — the same shape
  `gsd-tools.cjs` already used at two dispatch sites, so this follows an
  established idiom rather than inventing one.
- the profile-pipeline router's deliberately un-awaited `.catch(e => error(...))`
  turned an ExitError rejection into an uncaught exception; it now mirrors
  runMain's handling.

`edge-probe` and `ui-consideration-probe` gained `runMain` wrappers because
probe-core's new throwing default would otherwise have escaped them.

A follow-up sweep of every dispatcher — 19 command routers, the Hub, the
gsd-tools dispatch seams — found no further swallowing catch. The admitted
bound: ~1260 non-rethrowing catches repo-wide were scanned structurally but not
individually classified. Both real regressions were found by execution, not by
reading, so the suite is the detector that matters here.

`gsd-tools.cjs:253` stays a raw exit deliberately: it is the ensureRuntimeBuild
bootstrap, which runs before cli-exit is required, so the seam does not yet
exist. It needs a second allowlist entry, which means #3910's "single allowlist
entry" criterion is unachievable as written.

Verification runs on the remote runner.

Refs #3910

* enhance(#3910): ban the raw terminator by construction

Adds local/require-registered-exit and registers it on all four globs:
src/**/*.cts, scripts/**/*.cjs, hooks/**/*.js, gsd-core/bin/**/*.cjs.

Registering on the .cts glob is load-bearing, not redundant — the emitted .cjs
mirrors are globally eslint-ignored, so a rule registered only on the emitted
globs is blind to the sources. That is the #3496 lesson, and it is how the
previous guard became invisible: n/no-process-exit was 'error' in one block yet
fired zero times on all three surfaces that mattered.

The dead n/no-process-exit: 'off' block for hooks is deleted in the same PR.
Phase 7 migrated every hook, so the exemption now protects nothing.

Two allowlist entries, not the one #3910 anticipated. terminateNow's body is
detected STRUCTURALLY — a process.exit lexically inside a function of that name
— rather than by a path and line number that rots. The second is
gsd-tools.cjs's ensureRuntimeBuild bootstrap, an inline disable with its reason
at the call site: it runs before ./lib/cli-exit.cjs is required, so the seam
does not exist yet and no migration is possible. #3910's 'single allowlist
entry' criterion is therefore unachievable as written, and is amended with the
measurement rather than quietly missed.

The rule is proven able to FAIL, per glob: four positive controls, one for each
registered glob. A guard that cannot be shown to fire is not a guard. Four
matching negative controls pin process.exitCode as never-flagged — conflating
it with process.exit is what inflated this epic's original census 2x. An
allowlist case and a near-miss (same shape, different function name) fix the
structural detection in place.

Verification runs on the remote runner.

Refs #3910

* fix(#3910): stop the detached catch from throwing, and scope the allowlist

Review findings, one of them a regression the previous fix introduced.

_handlePipelineRejection called error() from inside a DETACHED .catch().
error() now throws, so that throw became an unhandled promise rejection — and
on Node >=15 with --unhandled-rejections=throw, Node dumps a raw stack trace
with absolute paths on top of the clean Error: line. That was impossible before
this branch, because process.exit(1) terminated synchronously before any
rejection machinery could observe it. The handler now writes byte-identical
stderr itself, in both plain and --json-errors form, and sets exitCode in
place. This was the THIRD interceptor found, and like the first two it surfaced
by running the CLI rather than by reading code.

The rule's terminateNow allowlist had no path constraint, so any function
anywhere named terminateNow across all four globs inherited it. It now requires
the structural nesting check AND a cli-exit.cts basename — still no line
numbers to rot.

The four per-glob positive controls only varied a filename inside RuleTester,
which never resolves eslint.config.mjs. Since the rule is filename-agnostic,
all four exercised identical logic and none proved the rule was WIRED — this
epic's own failure mode. A registration test now asserts the rule resolves for
a real path in each glob, and it is proven able to fail: removing one glob's
registration flips the resolved value from [2] to undefined.

Three evasions the rule cannot catch (computed member, aliasing, .call/.apply)
are documented in its header and pinned by tests, labelled as known limits
rather than endorsed, so a future change that starts catching them is a
deliberate diff.

Refs #3910

* docs(#3910): document the raw-terminator ban

Reference and Explanation via a new docs/features fragment (FEATURES.md is
generated from it, not hand-edited). How-To:
docs/how-to/resolve-a-raw-terminator-finding.md, indexed from docs/README.md —
a contributor whose code trips the rule picks among three replacements by
surface (runMain/ExitError for a CLI path, terminateNow for a hook,
process.exitCode where the process should drain), and needs to know why
process.exitCode is correct and never flagged, since conflating the two is what
inflated this epic's original census 2x.

The page also names the three patterns the rule cannot catch and says plainly
that using one to dodge it is a review finding, not a fix — documenting them
without that sentence would read as a sanctioned workaround.

docs/INVENTORY.md deliberately untouched: eslint-rules/ is not a tracked family
in the manifest (verified — a regen produced a zero diff), so a hand-written row
would desync the table from the family it claims to belong to.

Refs #3910

* fix(#3910): a catch that sniffs the message swallows an ExitError

The remote run returned 41 failures, and one of them was a live production
regression rather than a test artifact.

`cmdMilestoneComplete`'s unstarted-phase guard re-threw only when
`e.message.startsWith('Cannot mark milestone complete:')`. `error()` used to
`process.exit(1)`, uncatchable, so the guard always fired. It now throws an
ExitError carrying no message, the string test fails, and the ExitError was
silently swallowed — the guard stopped blocking milestone completion entirely.
Proven against the real CLI: pre-fix, a milestone with an unstarted phase
archived at exit 0; post-fix it is blocked at exit 1 with the intended message.

That is a guard that silently stopped guarding, which is this epic's thesis
appearing inside the phase meant to enforce it. Worth stating plainly: an
earlier census DID examine this site, saw a `throw e`, and classified it as
rethrowing. It was wrong — the rethrow is conditional, and a conditional
rethrow on an inspected message is indistinguishable from an unconditional one
unless you read the predicate.

So the class was swept rather than patched where it was tripped over. An AST
census of every CatchClause across src/, gsd-core/bin/ and scripts/ found 38
conditional rethrows. Two more had the same defect and are fixed the same way:
`config.cts`'s `'No config.json'` sniff and `gsd-tools.cjs`'s
`e.name === 'WindowsError'`. The remaining 25 are provably unreachable — every
one wraps a bare fs, YAML, manifest-require or git-exec primitive that cannot
throw ExitError — and two were scanner false positives, both explained. Each
fix is an unconditional `instanceof ExitError` rethrow placed BEFORE any
inspection, matching the idiom command-routing-hub and gsd-tools already used.

Residual bound, stated rather than implied: zero known-reachable unfixed sites,
contingent only on error() never later being called inside one of those 25
primitive try blocks.

The remaining failures were harness artifacts, and the harnesses were corrected
to the new contract rather than the assertions weakened. Tests that mocked
`process.exit` to observe termination now catch ExitError and assert its code;
tests parsing stderr as a single JSON object still assert exactly that, with
their ad-hoc `node -e` scripts wrapped in runMain so it is true. milestone and
phase-resolution-parity needed no test change — they were correctly written
against the real bug and are what caught it.

Verification runs on the remote runner.

* chore(#3910): backfill the changeset PR number

Also reframes the fragment to lead with the user-visible change — the
milestone guard blocking again — rather than the narrowest of the three fixes.

aaf47c5fc2 fix(#3691): let every reviewer lane take a prompt cap, and make the documented global resolve (#3832)
* test(#3691): failing-first coverage for the reviewer prompt budget

No prompt cap can reach any CLI reviewer lane, by any configuration. Two
independent defects compound: all nine `transport: spawn` lanes declare
`promptBudgetKey: null`, so `budgetFor` returns on its first line; and the
documented global `review.max_prompt_tokens` is advertised in the schema
manifest but declared nowhere, so the resolver never materializes it and
`budgetFor`'s fallback is dead code.

Adds to tests/reviewer-config-federation.test.cjs, which already owns the
per-reviewer budget config-set/config-get idiom:

- a CLI lane inherits the global cap (RED: reports null)
- an http lane with the -1 sentinel inherits the global cap (RED: reports null)
- the resolved review surface carries max_prompt_tokens at all (RED: absent)
- per-lane overrides the global on a CLI lane
- the sentinel boundary: -1 inherits, 0 means do-not-trim and must NOT read as
  unset, 1 is the smallest real budget — the regression budgetFor's own comment
  warns about
- anti-tightening pins that must stay green: an empty config leaves every lane
  null, the three existing budgeted lanes are unchanged, and config-set still
  rejects a per-reviewer key naming something that is not a declared lane
- a fast-check property over the resolution contract itself, with -1, 0 and
  non-finite inputs generated explicitly rather than left to chance

Every row was reproduced by hand against the real CLI before being written, so
the RED/GREEN split is observed rather than predicted.

Refs #3691

* fix(#3691): let every reviewer lane take a prompt cap, and make the global resolve

No prompt cap could reach any CLI reviewer lane, by any configuration. Two
independent defects compounded.

The nine spawn-transport lanes — claude, coderabbit, antigravity, cursor,
gemini, codex, kimi-code, opencode, qwen — declared `promptBudgetKey: null`, so
`budgetFor` returned on its first line and `review-lane plan` reported
`promptBudget: null` no matter what was configured. Each now declares
`review.max_prompt_tokens_per_reviewer.<slug>` with the same `-1`-is-unset
sentinel the three local-server lanes already use.

Separately, the central `review.max_prompt_tokens` was listed in the schema
manifest's validKeys and documented as a supported setting, but declared
nowhere — the resolved surface is built from capability declarations plus the
defaults manifest, and neither carried it. `configGet` returned undefined and
`budgetFor`'s documented fallback was dead code. It is now declared with a
`null` default, exactly as docs/CONFIGURATION.md already specified, so the
default behavior is unchanged: nothing configured means nothing trims.

Two things the diagnosis had not predicted, found and fixed while implementing:

- `REVIEWER_LANES` in src/review-lane-descriptor.cts is a second, hardcoded
  registration site that `mergeReviewerLanes` prefers over the capability
  registry on a slug collision. Editing only the capability files left every
  CLI lane still null. Both sites now agree.
- The generated `gsd-core/bin/lib/capability-registry.cjs` was stale and masked
  the capability edits; regenerated with `npm run gen:capability-registry`
  rather than hand-edited.

docs/CONFIGURATION.md said "Only lanes that declare a budget key accept one —
today ollama, lm_studio and llama_cpp". That is false as of this change and is
corrected rather than left to rot.

The trim-versus-refuse question the issue raises is deliberately not taken up
here: the refusal path already exists for the case that matters — a reviewer
whose minimum set exceeds its budget is skipped rather than sent a misleading
prompt — and trimming above that floor is the documented, shipped design of the
feature. Changing it would alter behavior for the three lanes that already
work, which is not what the issue asks for.

Fixes #3691

* fix(#3691): document the new global and narrow an invariant this change obsoleted

The full suite surfaced two consequences of giving every CLI lane a budget key.

`review.max_prompt_tokens` entered CONFIG_DEFAULTS without a matching entry in
the planning-config reference, which config-field-docs guards. Documented,
including the sentinel semantics a reader needs: a per-lane value overrides the
global, `-1` means unset and inherits it, and `0` means "do not trim that lane"
and is not unset.

The #2797 federation guard asserted that "a lane with no model flag and no host
owns no config keys". That held only because budget keys existed solely on the
three local-server lanes, all of which have hosts. A lane can now legitimately
own a config key for a third reason, so qwen tripped it.

The assertion is narrowed rather than weakened: such a lane must still own no
model key and no host key, and may own at most its own
`review.max_prompt_tokens_per_reviewer.<slug>` — never another lane's. That is
strictly more specific in the dimensions that still matter. Proven to still
bite: hypothetically giving qwen a `review.models.qwen` key fails it with
`model/host: review.models.qwen`. The name and comment cite #3691 for why the
premise changed, so a reader sees a deliberate narrowing, not erosion.

Checked the sibling assertions in that describe block; the other three do not
rest on the obsolete premise and are untouched.

Refs #3691

* fix(#3685): port the write-flag content-change contract to its three sibling sites

#3685 fixed `phase complete`'s `roadmap_updated` / `state_updated`, which
reported `fs.existsSync(path)` rather than whether the transaction wrote
anything. Three sibling sites carried the identical defect and are ported here.

- `cmdPhaseRemove` reported `roadmap_updated: true`, hardcoded.
  `updateRoadmapAfterPhaseRemoval` now returns whether the content changed and
  the flag reports it. #2640/#2974 already fixed `state_updated` at this same
  call site and left this one behind, so the correct shape was adjacent.
- `cmdMilestoneComplete` reported `state_updated: fs.existsSync(statePath)` —
  byte-identical to #3685's bug in a different command.
- `cmdMilestoneComplete` reported `milestones_updated: true`, hardcoded, never
  consulting the MILESTONES.md write.

`gsd-core/workflows/remove-phase.md:100` extracts `roadmap_updated` for display
and never branches on it, so the flip from always-true to content-based changes
no workflow behavior. Verified by reading the step, not assumed.

One trap found while implementing: the obvious in-memory
`finalContent !== originalStateContent` comparison — copying `cmdPhaseComplete`'s
shipped shape verbatim — gives a FALSE POSITIVE for milestone completion.
`platformWriteSync` normalizes Markdown at write time, and the milestone-closure
transform regenerates `## Current Position` fresh on every call, so its
pre-normalize output always differs from the already-normalized file on disk
even when the persisted bytes are identical. The comparison is therefore made
against the post-write on-disk content. `cmdPhaseComplete`'s own comparisons are
left untouched — their repeat-no-op tests pass, so they are not exposed to this
artifact.

`milestones_updated` has no reachable no-op: the MILESTONES.md write
unconditionally appends an entry every call. Only the true direction is pinned,
documented inline rather than faked with a passing test.

Refs #3685

* fix(#3685): compare write-flag content through the writer's own normalizer

An independent reviewer disproved a claim made while porting #3685's contract
to its sibling sites: that `cmdPhaseComplete`'s comparisons were not exposed to
the Markdown-normalization artifact already diagnosed in `cmdMilestoneComplete`.

`platformWriteSync` normalizes on write — CRLF stripped, blank-line runs
collapsed, a blank line inserted after a heading, a single trailing newline
enforced. Every flag that compares the PRE-normalization in-memory string
against the on-disk pre-image can therefore report a change when the persisted
bytes are identical. `cmdMilestoneComplete` had been worked around by re-reading
the file after the write; the other sites compared raw strings.

All of them now go through one exported seam,
`contentChangedAfterNormalize(filePath, before, after)`, which normalizes both
sides exactly as the writer does. That removes the extra disk read the milestone
workaround needed, and makes the sites agree by construction rather than by
four independent implementations of one rule — the divergence the repo names as
an anti-pattern.

Reachability, stated precisely rather than uniformly: the seam is load-bearing
at `cmdPhaseComplete`'s `roadmapUpdated`, `requirementsUpdated` and
`stateUpdated`, where section-rewrite logic genuinely regenerates content into a
different-but-normalization-equivalent shape. At
`updateRoadmapAfterPhaseRemoval` it is defense-in-depth: the no-match branch
never reassigns `content`, so the raw comparison was already correct there. The
first analysis claimed the reverse; this is the corrected finding.

Also fixes an unsound test premise the remote suite caught. The byte-identity
precondition in `roadmap_updated is false when ROADMAP.md comes out
byte-identical` asserted against a hand-authored, un-normalized fixture — so the
very first write reformatted it and the file could not come back identical. The
fixture is now written already-normalized, so the assertion compares a
normalized pre-image against a normalized post-image and still fails if the flag
regresses to a hardcoded `true`. Not platform-specific; it reproduces on macOS
too, and the earlier local check simply never exercised it.

The sibling true-direction and milestone tests were checked for the same premise
and do not share it — they assert `notEqual`, or compare two post-write states
produced through the same normalizing seam.

* feat(#3227): publish machine-readable state contract at step boundaries

Adds src/state-contract.cts, a best-effort publisher that writes
.planning/state.json (contract 1.0.0) at 11 step-boundary commands, so
external tools read a versioned contract instead of parsing STATE.md and
ROADMAP.md heuristically.

Composes existing owners rather than re-deriving: phase rows come from a
new locateProgressTable extracted from deriveProgressFromRoadmap (so the
snapshot can never disagree with GSD's own progress counters), milestone
identity from getMilestoneInfo, and next from classifyProject. Owners are
required lazily to avoid the state -> state-contract -> smart-entry ->
state require cycle.

Also fixes a pre-existing defect in scripts/lint-test-file-count.cjs
(maintainer-approved as a second concern): testEffectivePrefix never
stripped the suite qualifier, so 65 dotted test files counted against no
module and 9 mis-bucketed into a shorter one. Allowlist re-baselined for
the 74 files the gate can now see.

* test(#3227): shape hostile-name fixtures away from the scan corpus

The two hostile-input fixtures used a literal phrase from
scripts/prompt-injection-scan.sh's corpus, so CI's Security Scan redded on
this file. These tests assert that an arbitrary phase name round-trips into
state.json as inert data -- the property holds for any string, so the
injection flavor is illustrative, not load-bearing.

Reshaped to a hyphenated fake instruction tag, which stays hostile-looking
while matching none of the scanner's patterns. Allowlisting the file was
rejected: that mechanism is for suites whose subject IS injection defense,
and it would blind the scanner to this whole file permanently.

* chore(#3227): ratchet the state-contract mutation floor to its measured score

The module was registered at minScore 50, the ratchet's minimum permitted
floor for a newly-registered module whose score had not been measured. This
PR's own Stryker shard measured 66.25% (run 32769289750, job 97565813640),
so the floor moves to floor(measured) - 1 = 65, per the rule the registry
documents.

66.25 is below TARGET_MUTATION_SCORE (80), so this stays a ratchet
candidate: raise as the tests improve, never lower.

b42cb4fb29 fix(#3597): count scenario expectation failures in the QA gate, and fix the workstream scope split it exposed (#3607)
* fix(#3597): count scenario expectation failures in the QA ratchet gate

buildReport counts totals.violations as oracle violations PLUS scenario
expectFailures, but collectFindings read only step.violations. A scenario
whose declared expect failed therefore produced ok:false and violations:1
in the report while the ratchet printed "0 violations" and exited 0.

multi-workstream has failed that way on every CI run since 2026-08-10,
when #3217 (PR #3318) made computeProgressPercent withhold a percentage
whose scope is not COMPLETE. The walk detected the change the day it
landed; nothing was listening.

- collectFindings returns a third bucket, expectationFailures, carrying no
  fingerprint so it can never be baselined or acked away
- both modes of main() print and gate on it; the summary line reports it
- guard runMain(main) behind require.main === module, so the QA suite can
  require the script to test collectFindings without running a real walk
  (that import side effect is why the gate logic had no test)
- multi-workstream now asserts the true contract: phase_scope unreadable
  and percent null, per ADR-3180 7.6 rule 4
- the perturbation test asserts scenario ok, closing the test-side half

Closes #3597

* fix(#3597): resolve the milestone window against the active workstream

listMilestonePhaseDirs defaulted its ws option to null. planningDir
treats undefined as "resolve the ambient workstream" and null as
"force the project root", so that default suppressed the ambient
resolution every other planning-path read uses.

All 18 call sites derive phasesDir ambiently via planningPaths(cwd),
so the counts came from the workstream while the milestone window came
from the root .planning/ROADMAP.md — the exact numerator/denominator
scope split ADR-3180 7.6 rule 3 forbids. workstream create migrates
that root roadmap away, so the read threw and scope stayed UNREADABLE,
and rule 4 then correctly withheld the percentage.

Proof: with a workstream tree byte-unchanged, copying its own ROADMAP
to the project root flipped --ws alpha progress from
phase_scope:unreadable/percent:null to complete/100.

This is the defect the loop QA walk was pointing at all along; the
scenario expectation is restored to percent:100 rather than bent to
match the bug.

- pass ws through as undefined so ambient resolution applies
- multi-workstream asserts phase_scope complete + percent 100
- regression test in completion-ratio-scope-withholding covers a
  workstream-only project with no root ROADMAP
- replace the vacuous require.main test: runMain defers through a
  promise, so the in-process timing check passed against the unguarded
  file too; a child-process spawn now observes the guard for real
- tie the oracle-violation test to expectationFailures, and cover the
  absent-key, multi-scenario and zero-step report shapes in parity
- flatten scenario-authored strings before rendering them into the
  step summary and CI logs (forged markdown / ANSI injection)
- widen the scenario contract assertions past perturbation-* so
  multi-workstream is actually covered test-side

Closes #3597

* fix(#3597): flatten scenario-authored strings on the CI-log output path

The step-summary path already routed findings through flattenUntrusted;
the check-mode NEW-smell and STALE-entry console.error blocks, and the
repro line in both printers, still interpolated raw.

detail carries a scenario-authored expect[].path verbatim, and
reason/scenario/id come from contributor-authored baseline and ack
fragments validated only as non-empty strings. A crafted path could
print a forged summary line into the CI log directly above the real
one, plus ANSI repaint and unbounded length.

Exit codes are unaffected — this is log spoofing, not gate bypass.

* fix(#3597): refuse to archive on an unreadable milestone window; close review gaps

Resolving the milestone window against the active workstream can leave
the window UNREADABLE when that workstream has no ROADMAP of its own.
getMilestonePhaseFilter throws, the window degrades to a pass-all
fallback, and milestone complete would then move every phase dir --
breaking the guarantee stated at the archive site that no out-of-window
directory is touched.

milestone complete now refuses to archive when the window is UNREADABLE
and reports the refusal; --dry-run previews the same refusal from the
same shared derivation.

The guard is scoped to UNREADABLE, not to every non-COMPLETE scope. A
broader condition regressed ordinary root projects: the QA walk caught
milestone-rollover leaving 01-parser on disk, which then tripped the
#1447 abort in phases clear. UNSCOPED and TRUNCATED are pre-existing
classifications and keep their existing behavior.

Review fixes:
- the workstream regression test asserted complete/100 but its fixture
  wrote no workstream STATE.md, so it resolved unscoped/null and the
  test failed; it now asserts a milestone and genuinely fails-first
- the parity test hand-supplied totals.violations, hardcoding the very
  formula under test; at least one case now goes through the real
  buildReport
- drop a vacuous qa-report.json assertion (jsonOut defaults to null, so
  no report is written by either shape)
- buildRepro emitted a repo-relative binary path after cd-ing into a
  temp project, so every repro died with MODULE_NOT_FOUND; it now
  resolves an absolute path
- flattenUntrusted truncated the repro to 300 chars, handing reviewers a
  command that looks complete and is not; length capping is now opt-out
  for repro while newline/control/backtick stripping still applies

d922469613 refactor(#3408): close the two known limits instead of recording them (#3524)
* refactor(#3408): close the two known limits instead of recording them

Both of these were flagged in review and written down as 'known limits' in a
PR body and an issue comment. CLAUDE.md is explicit that a note is not a fix
and is not surfacing — it is a silent defer. Recording them while closing the
epic was the pattern this epic exists to remove, performed on the epic itself.

syncAndPreserveStateMd and applyPostSyncPreservation each took eight
positional arguments, the last three optional, one of them an out-param. The
review's own wording was that 'a third consumer should trigger an
options-object refactor' — a deferral with a trigger condition nobody would
notice firing. Content and path stay positional; resync, authoritativeFm,
deriveProgressKeys and divergedFields move into a named
StatePreservationOptions. Every call site updated, with tsc as the proof none
was missed.

cmdStateCompletePhase's updated array carried both field labels and a section
name, worked around by a SECTION_ENTRIES Set that re-derived the distinction
by string matching. The kinds are now typed where they are produced and
flattened once at output.

Output contract unchanged: updated is still a flat string array with the same
entries in the same order.

Behavior-preservation was proven rather than asserted — the compiled lib was
built at 411196bc3 and post-fix, and the same fixtures run through each. Both
byte-identical, modulo the clock-driven last_updated.

* fix(#3408): update every non-typed call site, and make a wrong options call loud

The previous commit claimed 'tsc is the proof a site was not missed'. That was
wrong and I asserted it. tsc type-checks src/ only; the test call sites are
plain .cjs and are not checked at all. Fourteen tests failed with
divergedFields: [] because a positional resync boolean landed in the options
slot and every option came through undefined.

Nine stale call sites converted. Also caught: the drift guard suite's E2
fixture embedded the old call shape 'verbatim from src/milestone.cts' — a
fixture that mirrors production and had silently drifted from it.

The deeper defect is that the refactor itself introduced the failure shape
this epic exists to remove. An options-object parameter is silently
mis-consumable by any non-TypeScript caller: pass the wrong thing and the
function proceeds with every option undefined, returning a well-formed,
plausible, empty result. That is precisely ADR-3408's Context section,
reintroduced by the change meant to tidy the code up.

Both functions now assert their options argument is a non-null object and
throw STATE_PRESERVATION_OPTIONS_INVALID carrying the offending type, mirroring
throwUnwiredRow. A test pins that the guard fires on the exact mistake that
produced these fourteen failures.

Verified by probe rather than asserted: a correct options call returns the
expected divergedFields; a legacy positional call throws with the structured
code instead of silently returning empty.

* chore(#3408): drop the changeset — this PR has no user-facing impact

CONTRIBUTING.md: 'PRs with no user-facing impact (test refactors, lint config
changes, CI tweaks, formatting-only changes) can add the no-changelog label.'

Typing this Changed and then exempting it from the docs requirement would have
been wrong twice: it publishes a CHANGELOG entry under Changed when no command
output moves, and it uses a per-fragment exemption to paper over a type that
was wrong to begin with.

Both refactors are behavior-preserving, verified byte-identical against the
pre-change compiled lib. The one new throw guards a module-private seam in
src/state.cts that no external caller can reach.

* refactor(#3408): derive StatePreservationOptions, narrow the guard message

Two findings from the orthogonal reviews on the close-known-limits PR.

StatePreservationOptions repeated all four ReadModifyWriteOptions fields, differing only in resync being required, and divergedFields carried a second independently-worded docstring. It is now derived via Omit so the shared fields have one definition and cannot drift out of hand-sync.

assertStatePreservationOptions echoed JSON.stringify(options) into the thrown message text. The contract for that guard is a structured code plus the offending type, not the value; echoing the value would become a disclosure path if a caller ever passed user-derived data. Removed from the message; err.code and err.receivedType are unchanged, and the test asserts on those.

411196bc3a refactor(#3471): one enforcement point for the empty case, and reports that match the disk (#3519)
* refactor(#3471): one enforcement point for the empty case, and reports that match the disk

Implements ADR-3408 section 8.5 and section 8.4's residue (folded in when Phase
3 closed as subsumed). Four items, and two findings the design did not predict.

FINDING 1 — the guards could not simply be deleted, as the design instructed.
state sync and REGENERATE_STATE never run applyStatePreservation at all, so
those six conditions were their ONLY empty-field fallback. A baseline probe on
the unedited tree confirmed unconditional deletion drops current_phase,
current_phase_name, current_plan, stopped_at and paused_at from a blank-body
STATE.md on state sync — breaking the byte-identical requirement section 8.3
grants those two sanctioned-permanent exceptions. They are now GATED, not
deleted: on for the exceptions, off for the write seam, where an empty derived
value finally reaches the executor unmolested.

FINDING 2, the more serious one — there was a FOURTH encoding of this policy.
The pre-existing #2202 unknown-key carry-forward loop independently restored
the same six fields whenever derivedFm lacked the key, completely neutralizing
the fix. It is named nowhere in the ADR, the design, or three prior phases. It
was found only because a probe that should have passed did not: the first
attempt reported divergedFields: [] and silently restored both fields,
reproducing the exact bug this phase exists to close.

That is worth stating plainly. This epic's thesis is 'policy declared in one
table, enforcement hand-rolled per call site.' The final phase found one more
call site than anyone had counted — which is the fourth consecutive time a copy
count in this epic proved to be a lower bound.

Also: divergedFields could only observe fields the executor actively RESTORED,
by diffing postFm. A discard-to-empty is absent both before and after, so it
was invisible. A second pass now reports it, which is what makes section 8.5's
'preservation is visible' true for the delete-the-body-line case rather than
aspirational.

cmdPhaseComplete now reports what it preserved — #3374 was filed against that
command and its complaint was warnings: [], silence.

cmdStateJson's private third copy of the guards is routed onto the executor's
preserve-when-unchanged rule. A read is definitionally not a write, so the
#1230 delta is 'unchanged' and curated wins over a stale annotation.
shouldPreserveExistingProgress is a different rule and is untouched.

Report reconciliation is ONE shared helper across seven commands, not five
copies of fix(#3351)'s block. Five copies of a reconciliation is precisely the
shape this epic removes, and introducing it in the final phase would have been
a poor joke. Both untraced commands were traced rather than assumed:
cmdStatePlannedPhase matched cmdStateBeginPhase exactly; cmdStateCompletePhase
turned out to be a different legacy hand-rolled path reporting a mix of field
names AND a section name, where the naive helper would have dropped 'Current
Position' as a false negative every time.

* test(#3471): characterization coverage for one enforcement point and reconciled reports

Matrix sections A-E, asserted at the consumer's output per ADR-3180 Decision
4(b)/(c) — this phase owes Decision 5's outcome metric, the one the drift
guard's zero may never be reported without.

Three walls matter more than the new coverage:

  A2 is SIX separately named tests, one per gated guard, not one parameterised
  assertion over a list. A list is trivially shortened later; six named tests
  are not, and six guards is exactly where a field gets silently dropped.

  A6 pins what Phases 1-3 already fixed — non-empty stale body, delta
  unchanged, losing to fresher curated frontmatter, with the divergence
  reported. If A6 reddens, this phase broke the thing the epic was for.

  D1/D2 pin state sync byte-identical. The implementation had to GATE the six
  guards rather than delete them precisely because state sync has no executor,
  and a baseline probe showed unconditional deletion drops five fields.
  Nothing else in the suite would notice that regression.

E6 covers #3345's direction — a field preservation restored that the intent
never named IS reported. Nothing has ever tested that direction.

Assertions were empirically verified against the compiled lib and the real CLI
before being written, since the suite cannot be executed locally. That caught
two type bugs in the draft: fm.current_phase after a quoted-YAML round-trip is
the string '5', not the number 5.

E5 is recorded as structurally unreachable rather than weakened or faked. Those
four commands report body Title-Case labels, which cannot string-collide with a
frontmatter snake_case key the way cmdStatePatch's arbitrary field names can —
which is why fix(#3351) targeted only cmdStatePatch. Testing it directly would
need reconcileReportedFields exported from private scope; the helper is
exercised through E6 and all seven commands instead.

* docs(#3471): amend ADR-3408 section 8.5 — a fourth enforcement point, and guards that could not be deleted

Amendment 3. The contract held; two of section 8.5's own statements did not.

It said the six empty-only guards are DELETED. They cannot be. writeStateMd is
the sole path for both section 8.3 sanctioned-permanent exceptions and never
runs applyStatePreservation, so those guards were their only empty-field
fallback. A baseline probe on the unedited tree confirmed unconditional
deletion drops five fields from a blank-body STATE.md on state sync, breaking
the byte-identical guarantee section 8.3 grants it. They are gated instead.

It also mis-located cmdStateJson's guards, describing them as living in
syncStateFrontmatter. They were a separate private copy on the read path with
no delta check at all, so a stale body annotation always beat fresher curated
frontmatter in state.json — #3395's shape entirely outside the write seam.

THE FINDING: a fourth enforcement point nobody had counted. The pre-existing
#2202 unknown-key carry-forward loop independently restored the same six
fields, silently neutralizing the fix. It is named nowhere in this ADR, in the
phase design, or in three prior phases, and was found only because a probe that
should have passed did not.

Fourth consecutive time a copy count in this epic proved a lower bound: 2
write-seam bypasses became 4, three preservation encodings became four, and the
estimate was wrong every time. ADR-3180's standing rule has earned itself in
every phase — read the code, not the write-up.

Records the Row 2 decision (a discard-to-empty wins per the delta rule and is
reported, not silent — the sharpest Hyrum exposure in the epic), section 8.4's
residue landing as ONE shared reconcileReportedFields across seven commands
rather than five copies, and the parity assertion added because
FRONTMATTER_KEY_TO_BODY_LABEL was itself a second table that failed silently —
this epic's shape in miniature, in its final phase.

* fix(#3471): repair four regressions the checkpoint caught

Checkpoint returned 16 failures of 34389: six real regressions in pre-existing
tests, plus seven of my own test bugs.

My hypothesis was wrong and is recorded as such. I predicted the #2202
carry-forward skip was the cause, reasoning it had removed a load-bearing
fallback the way the six guards nearly were. It was not implicated in any of
the six. Three unrelated causes:

#2111 — current_phase came back undefined from milestone complete, which is
the epic's own defect class reintroduced by its final phase. Root cause is
Row 2 working exactly as designed: milestoneCompleteCore rewrites the body
Phase: line to a closure message, so current_phase's #1230 delta reads
CHANGED and the new rule correctly discards the curated value. The transition
never declared any intent to touch that field. Fixed by re-asserting
current_phase and current_phase_name through authoritativeFm — the existing
#2736 mechanism beginPhaseCore and completePhaseCore already use — rather
than by weakening Row 2, which A5 pins.

That interaction is worth naming: a rule that keys on 'did this write change
the body source' will fire on a transition that moves the body line for an
entirely unrelated reason. The design did not anticipate it.

#1264 / #3242 / the state.patch progress report — reconcileReportedFields
folded EVERY divergedFields entry into updated, including preserve-always
progress restores no caller asked about. Now scoped to preserve-when-unchanged
rows only.

#1162 / case-insensitive table fields — valueOf checked frontmatter before
body, so a lowercase table field name exact-matched the lowercase frontmatter
key sync always derives, comparing stale pre-sync body text against a
post-sync frontmatter enum. Flipped to body-first.

That last one is the SAME lesson as Phase 2's patchCore, recurring in a
different function two phases later: in this model the body is authoritative
and frontmatter is the projection, so a name that could mean either resolves
body-first. Twice now.

Test bugs: a stray unused parameter shifted every argument at six call sites,
so body arrived undefined; and A4 compared nested progress scalars against
numbers when extractFrontmatter returns raw YAML strings. The string-vs-number
YAML round-trip has now been caught three times in this phase alone.

* test(#3471): one helper for the progress coercion that bit four times

A2f failed on the string-vs-number YAML round-trip: extractFrontmatter returns
nested progress scalars as raw YAML strings, so a comparison against numeric
literals can never pass.

This is the FOURTH time this exact class has been caught in this phase — twice
during test authoring, once as A4 in the previous checkpoint, now as A2f.
Patching it a fourth time by hand would guarantee a fifth.

Added numericProgress() with a comment saying why it exists, and routed every
progress-reading assertion in the #3471 block through it. Swept the block:
C3 needed no change, because cmdStateJson's output already runs through
normalizeProgressNumbers.

Deliberately NOT shared with frontmatter.test.cjs's readPersistedProgress:
that one is path-based and re-reads from disk, while these assert on an
in-memory string that is never written. Sharing would have meant either a
disk round-trip these tests do not do, or duplicating half the helper — so
the coercion pattern is mirrored locally and the reason recorded, rather
than manufacturing a dependency to satisfy the letter of consolidation.

e2f4c16d9e refactor(#3469): one composition for the STATE.md write seam (#3501)
* docs(#3469): amend ADR-3408 section 8.3 — the pipeline has sanctioned exceptions

Section 8.3 read 'Every STATE.md write applies the pipeline.' That is false by
design for two commands, and acting on it would have inverted a shipped
feature.

Preservation makes curated frontmatter win over a re-derived body value.
state sync exists to do the opposite — #905's 'body annotation beats existing
frontmatter when both are present'; it re-derives frontmatter FROM the body.
REGENERATE_STATE is a factory reset that rebuilds STATE.md from scratch.
Applying the pipeline to either would re-lock exactly what the command was
invoked to replace.

This issue's own scope line, inherited from the epic, said to route the direct
writeStateMd callers through the pipeline. For cmdStateSync that would have
shipped silently, with every gate green, because no test asserts that sync
LETS the body win. Caught by reading the helper's docstring and then verifying
the claim against the code — a stale comment had already misdirected this epic
once.

Both commands are now named in a closed exception list and are permanent
ratchet entries.

Consequence recorded rather than left to bite Phase 4: the 'drive the ratchet
to 0 and delete the file' target in this ADR and in #3471 is wrong. Two
entries are permanent, so the correct end state is 2, and the honest report is
'0 removable bypasses, 2 sanctioned'. A guard reaching 0 here would only do so
by having stopped looking at two real writers.

* refactor(#3469): one composition for the write seam, not one per caller

Implements ADR-3408 section 8.3 as amended.

syncAndPreserveStateMd is now the single composition of syncStateFrontmatter
and applyPostSyncPreservation. readModifyWriteStateMd and cmdPhaseComplete
both CALL it instead of each assembling the two steps themselves.
cmdPhaseComplete keeps its own writePlanningFileSet envelope — the
composition returns content, it does not take over the write, so STATE.md
still commits atomically with ROADMAP and REQUIREMENTS.

Assembling the stages at a call site is a re-derivation even when every step
calls an owner. Upstream's fix(#3374) routed cmdPhaseComplete through
applyPostSyncPreservation but left it calling syncStateFrontmatter directly
first, so the composition was duplicated and free to diverge with both guards
green. That is ADR-3180 Amendment 2's finding repeating on the write side.

cmdMilestoneComplete gains preservation. It wrote through writeStateMd, so it
got sync and no preservation — the identical shape #3374 reported for
phase.complete, and flagged upstream as a follow-up in the helper's own
docstring. This is that follow-up.

Divergence is now visible: preservation_warnings names each field restored
over a disagreeing derived value. Deliberately NOT named warnings —
cmdPhaseComplete already exposes warnings as a prose string array, and two
sibling commands carrying that name with different element types is
Generative Fix Divergence, the class this epic exists to remove.

patchCore stops running stateReplaceField over the whole document. One
observable consequence, intended per design row 9: a frontmatter-shaped patch
key with no body counterpart now reports failed instead of silently
succeeding, because the old whole-document match was literally hitting the
YAML line case-insensitively.

The guard closes Phase 1's DECLARED KNOWN GAP as promised rather than
re-deferring it: section 8.3(b) detection is tractable now the composition
exists. Scoped by two factors to avoid Phase 1's measured 29-to-1 false
positive rate — a variable field-name argument AND a content argument whose
nearest preceding assignment is not stripFrontmatter. Verified 0 findings and
0 false positives across all 33 call sites, plus 5 synthetic shapes. It also
detects the re-assembly shape above.

Ratchet: 4 entries to 2, both sanctioned-permanent. cmdStateSync's owner
changes from #3471 to sanctioned-permanent per Amendment 2 — routing it
through preservation would invert the #905 contract.

Also fixed inline rather than deferred: cmdMilestoneComplete's STATE.md read
now happens inside withStateLock. It previously read outside any lock before
writeStateMd took its own, leaving a TOCTOU window under concurrent writers.

* test(#3469): characterization coverage for the single write seam

Matrix sections A-E. Criterion 6 was amended by maintainer decision — all five
instances closed by point fixes while Phase 1 was in flight — so these are
characterization tests at the consumer's output per ADR-3180 Decision 4(b)/(c),
paired with the drift guard's count, never either alone.

Section C is the one that earns its keep. cmdStateSync is a sanctioned
permanent exception: state sync exists to re-derive frontmatter FROM the body,
so preservation there re-locks exactly what the command was invoked to
replace. C1 pins that the body wins; C4 pins that this phase left the command
byte-identical. Nothing else in the suite would notice if a future change made
sync start preserving, and the natural reading of 'one write seam' is to make
precisely that change.

Section E pins the guard's false-positive scoping. E4 (updateCore's
strip-then-replace) and E5 (sectionBody-scoped calls) must NOT be reported —
the naive detector measured 29 false positives to 1 true positive in Phase 1.
E7 is the inverse: a sanctioned-permanent entry disappearing must FAIL,
because a guard reaching zero here would only do so by having stopped looking
at two real writers.

Also corrects a stale test that asserted patchCore's old whole-document
behavior, which this phase deliberately changes.

One honest limitation, flagged rather than papered over: A1's 'byte-identical
to pre-refactor' cannot be diffed against real pre-refactor bytes from inside
the suite. It is implemented as the seeded fast-check property that
cmdPhaseComplete's composed output equals readModifyWriteStateMd's for the
same inputs — the strongest available proxy, not the literal claim.

* docs(#3469): refresh the seam glossary entry and add the changeset

Two spec-review gaps, both real.

CONTEXT.md's STATE.md Transition Module entry named three direct writeStateMd
callers including cmdMilestoneComplete. This phase routed that one through the
composition, so the line was false the moment the refactor landed.

Worth recording plainly: I wrote that sentence in Phase 0, correcting an
older stale pointer in it, and my own Phase 2 change invalidated it again
within the same epic. That is the exact drift this epic exists to remove,
demonstrated on the epic's own documentation — and it is why the entry now
ends by saying the whole-repo drift guard, not this line, is the authoritative
count.

The entry now records the composition (syncAndPreserveStateMd) and states that
exactly two direct callers remain, both SANCTIONED PERMANENT rather than debt.

Changeset: type Changed, because milestone complete's observable output moves.
Tier-2 per ADR-3180 Decision 3 — a stale body line no longer wins over fresher
frontmatter, and the command gains preservation_warnings. Docs requirement is
met by the ADR amendment already in this diff.

* test(#3469): register property-test temp-dir cleanup at creation time

Standards review, minor but real: the new fast-check property cleaned up its
temp dirs in a loop AFTER fc.assert returned. A genuine property failure
throws, so that line never ran and every dir from the failing run — including
all of fast-check's shrinking iterations — leaked.

The failure path is exactly when a littered machine hurts most, and a failing
property test is the case the test exists for.

Cleanup is now registered with t.after() at dir-creation time, so teardown
happens however the test exits. Not try/finally — CONTRIBUTING.md:356 bans it
inside test bodies, which is why the after-the-assertion shape existed in the
first place.

Swept the rest of the branch's test diff for the same shape; phase.test.cjs
already uses registered teardown and nothing else matched.

* fix(#3469): patchCore routes frontmatter writes instead of dropping them

Checkpoint returned 10 failures of 33880. One implementation defect, three
test defects, one stale test — all fixed, and the implementation defect is the
one that matters.

patchCore stripped frontmatter and then reconstructed it VERBATIM, applying no
patches to it. An arbitrary custom frontmatter key with no body counterpart and
no FIELD_CLASSIFICATION row — risk_level in the upstream fix(#3351) test —
therefore always reported failed and silently never wrote. It worked before,
via the old whole-document match on the raw YAML line.

That is a regression against this phase's own design row 9, which requires
frontmatter changes to ROUTE THROUGH the seam — still work, policy-governed —
not to stop working. Removing a capability is not routing it. An upstream test
caught it, which is the argument for running the checkpoint before believing
the refactor.

patchCore now partitions by frontmatter shape, decided structurally from the
parsed frontmatter's own keys rather than a naming heuristic:
  - classified keys still report failed — policy owns them and a raw patch may
    not bypass it;
  - unclassified keys apply to the frontmatter object and report updated —
    Phase 1's behavior-table row 19, a field with no row is not this contract's
    business;
  - body-shaped keys are unchanged.

The property 'failure' was my own test breaking the repo's Clock Seams rule.
The two paths agree byte-for-byte; the only difference was last_updated,
stamped from the wall clock on two invocations milliseconds apart, so it could
never pass. Time is now frozen with mock.timers across both — not by excluding
last_updated from the comparison, which would have silently stopped comparing
a field the composition writes.

B4's fixture could not discriminate: normalizeStateStatus maps any text
containing 'complete' to 'completed', and milestone complete's own new body
value derives to exactly that — which was also the fixture's stale value. The
stale value is now 'executing' so the assertion can tell 'body correctly won'
from 'stale survived'.

B5's fixture tripped a pre-existing unstarted-phase guard before reaching any
write-seam code; it now has the matching phase directory.

D9 asserted the old exempt set. readModifyWriteStateMd now calls one symbol
rather than assembling two, so it needs no exemption; syncAndPreserveStateMd
is the sole legitimate composition site.

* fix(#3469): patchCore resolves body-first, so the body wins a name collision

Re-verification returned 2 failures of 33880, both D4 — the hostile row for a
key that exists as BOTH a frontmatter key and a body field.

The partition checked frontmatter first, so 'status' — classified in
FIELD_CLASSIFICATION and also present as a body 'Status:' line — routed to the
frontmatter branch, was rejected as classified, and reported failed.

Wrong order. Patching 'status' means the body field, and upstream fix(#3351)
says so in its own comment: 'the legitimate working case for state.patch is
display-cased BODY fields — Status, Current Plan, Phase.' The body is
authoritative in this model; frontmatter is the projection. D4 asserted
exactly that and was right.

Resolution order is now body, then frontmatter:
  1. resolves to a body field -> apply to body, updated
  2. else an own key of the frontmatter:
       classified   -> failed  (policy owns it)
       unclassified -> apply to frontmatter, updated
  3. else -> failed

Verified by probe against the compiled lib for all four cases rather than
asserted: risk_level (frontmatter-only, unclassified) still lands;
current_phase still fails; display-cased Status unchanged; D4's lower-cased
status now lands via the body with the frontmatter untouched.

The current_phase case was the one that could have regressed silently, so its
fixture was read rather than assumed — D1's body carries 'Phase: 3 (alpha)'
and no 'Current Phase:' line, so body-first cannot reach it.

69e7afd0c7 chore(#3212): bounded quantifiers over document content — prohibition with teeth — Phase 4 (#3441)
* 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
mistakenly carried meta.docs.category: 'Portability', copied from a sibling
rule without realizing what that implied: docs/contributing/cross-platform-
portability-rules.md governs an ADR-1703 rule family under a hard "zero
escape hatches" contract (tests/portability-rule-disable-ban.test.cjs's
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
  content.match(/<tag>([\s\S]*?)<\/tag>/) reads of this repo's own
  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.

0624c5da6f chore(#3212): src/text-lines.cts is the sole owner of line-terminator handling — Phase 2 (#3420)
* 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).

Test matrix: .gsd/phase/chore-3413-text-lines-seam/50-test-matrix.md

* 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.

Six-gate ripple: .gitignore, eslint.config.mjs (src/**/*.cts block),
docs/INVENTORY.md + INVENTORY-MANIFEST.json (regenerated), CONTEXT.md
glossary (Text Lines Module, mirroring Phase 1's Pattern Module entry).

* 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).

dc3c81e93d chore(#3212): src/pattern.cts is the sole owner of runtime-value regex construction — Phase 1 (#3416)
* test(#3412): failing-first suite for the pattern-construction seam

Phase 1 of epic #3212 (ADR-3212 §1/§2/§7). Tests only — src/pattern.cts
and eslint-rules/no-adhoc-regex-escape.cjs do not exist yet, so both
suites fail with MODULE_NOT_FOUND, which is the intended RED.

Locks the measured behavior rather than the assumed behavior:
RegExp.escape hex-escapes the leading character of nearly every string
("abc" -> "\x61bc"), so the suite asserts match-equivalence against an
inlined historical oracle (the implementation being deleted) rather
than byte-equivalence of pattern text — 200 seeded fast-check runs plus
a fixed corpus, 0 mismatches. Also locks the latent character-class
range bug this phase fixes as a side effect: a hyphen-bearing value
interpolated into [...] currently forms a real range and matches an
unintended character; post-migration it must not.

* chore(#3412): src/pattern.cts owns runtime-value regex construction

Phase 1 of epic #3212 (ADR-3212 §1/§2/§6/§7). Adds the pattern seam
delegating to the built-in RegExp.escape, deletes every hand-rolled
copy, and raises the Node floor to the Active LTS line.

The census was low, three times over. ADR-3212 counted 10 copies; a
graph query found 12; the new lint rule — once live — found 27 more.
The difference is that the census counted named helper FUNCTIONS while
the rule counts the escape SHAPE, so inline .replace(<class>, '\$&')
copies were never in scope. ADR §1's actual requirement is that no
module outside the seam escapes a value for regex use, so all of them
are, and CLAUDE.md's no-defer rule makes them this change's work.
Fourth consecutive epic here whose copy count was low — the argument
for ADR-3180 Amendment 3's "state N found by the guard" rule.

Also corrected mid-implementation: the survey reported phase-id.cts's
escapeRegex had 0 external importers. It had 8 production importers,
making its removal a public-surface change to an ADR-2121-owned module
and requiring an update to that ADR's locked-surface test. Blast
radius revised Medium-High -> High.

RegExp.escape is match-equivalent but NOT text-equivalent: it
hex-escapes the leading char of nearly every string ("abc" ->
"\x61bc"). Equivalence is proven by a seeded fast-check property test
against the deleted implementation as oracle. It also fixes a latent
bug: a hyphen-bearing value interpolated into a character class
previously formed a real range and matched an unintended character.

Node floor 22 -> 24 (RegExp.escape is Node 24+), across engines,
.nvmrc, package-lock, 9 CI matrix entries, and 5 docs. The aggregate
`required-tests` context is unchanged and no job was added or removed,
so branch protection cannot be orphaned by the dropped lanes.

Enforced by eslint-rules/no-adhoc-regex-escape.cjs (shape-matched, with
structural provenance for reviewed pattern-fragment constants rather
than a name heuristic) plus a whole-tree companion guard covering the
directories ESLint's globs miss.

* fix(#3412): close the _SOURCE guard evasion, correct two false claims

Three findings from the orthogonal review pass, all fixed.

1. The ESLint rule's `_SOURCE` provenance fallback was pure identifier-
   name matching with no binding check, so `new RegExp(userInput_SOURCE)`
   — a function parameter — sailed past the guard. That is the same
   rename-evasion class issue #3410 documents, reopened by the very
   fallback meant to complement the structural check. Now bound to the
   identifier's actual binding kind: import, require-derived const, or
   module-scope const; parameters, `let`/`var`, and unresolvable
   bindings fail closed. Four RuleTester cases cover the evasion and
   prove the legitimate cross-module case still passes.

2. src/pattern.cts's own header carried the stale pre-correction counts
   (12 copies / 17 call sites) while CONTEXT.md and the design doc
   carried the corrected ones (~39 / ~44) — a self-contradiction inside
   the PR whose entire purpose is deleting divergent copies. Rewritten,
   preserving the durable lesson: a named-function census cannot see
   inline copies; only a shape-matching guard can.

3. The claim that all deleted copies threw TypeError on non-string was
   false. phase-id.cts's copy — the one with 8 external importers — did
   String(value).replace(...) and never threw. The seam's locked
   signature does not coerce, so this is a real, now-disclosed behavior
   change rather than the pure preservation the tests asserted. Audited
   all 32 invocations across the 8 importers and 6 in-file callers:
   every one is safe by construction (upstream truthy guard or a
   string-producing derivation), verified by runtime probe against the
   compiled modules rather than by TS compilation, which cannot see a
   runtime undefined. Corrected the false claim in both the test comment
   and the design doc, and added it to Known limits.

* docs(#3412): add Changed changeset for the Node 24 floor

The only user-visible break in this phase. The escape-behavior change
is internal and match-equivalent, so it carries no user-facing note.

* fix(#3412): resolve the seam's require graph in script fixtures and packaging

Checkpoint 2 came back red with 90 failures on the node24 lane. Three
distinct defects, all introduced by routing scripts/ through the new
pattern seam, none reproducible by any local gate:

1. ~82 failures — tests/adr-index-gate.test.cjs and
   tests/removed-but-needed-lint.test.cjs copy a scripts/*.cjs into an
   mkdtemp fixture and spawn it there (necessary: those scripts resolve
   their scan root from __dirname/.., so running the real script would
   scan the real repo). Each harness hand-listed the dependencies to
   copy alongside. Adding require('../gsd-core/bin/lib/pattern.cjs') to
   gen-adr-index.cjs made both lists silently incomplete ->
   MODULE_NOT_FOUND, plus 17 downstream 'did not emit parseable JSON'
   failures from the same crash.

   Fixed as a class, not an instance: new tests/helpers/copy-script-
   fixture.cjs walks a script's transitive static relative-require graph
   and copies it, so dependencies are derived and never re-declared. It
   throws (naming the unbuilt artifact) instead of letting the child die
   with a bare MODULE_NOT_FOUND. Verified for all four seam-consuming
   scripts: gen-adr-index, lint-removed-but-needed, gen-loop-host-
   contract, sync-runtime-launcher.

2. 2 failures — scripts/ ships wholesale but eslint-rules/ does not, so
   the new scripts/lint-no-adhoc-regex-escape.cjs would be
   MODULE_NOT_FOUND in a published install (#2858 guard). Excluded from
   the tarball, matching the existing precedent for gen-emitted-
   baseline.cjs, which is excluded for the identical reason, and locked
   with a test modeled on that one. Confirmed against a real npm pack:
   890 files, 0 from eslint-rules/, and gsd-core/bin/lib/pattern.cjs
   present (so the other four scripts' requires are legitimate).

3. 6 failures — tests/phase-id.test.cjs asserted the literal escaped
   source text ('0*29', 'PROJ-42'). RegExp.escape is match-equivalent to
   the retired hand-rolled escaper but NOT text-equivalent: it hex-
   escapes the leading character and all hyphens ('0*\x329',
   '\x50ROJ\x2d42'). Verified NOT a behavior change — 576 match
   decisions across all three real interpolation prefixes, zero
   divergence. Those tests now compile each source into the same heading
   regex src/roadmap.cts's searchPhaseInContent builds and assert what
   matches and what does not, including the 'i'-flag canonicalization
   the hex escape has to preserve. Re-pinning the new literals would
   have rebuilt the same brittleness one layer down. Adds a test for the
   property the escape exists for: a dot in '1.2' must not act as a
   wildcard.

Also shares one definition of 'a require' between the packaging guard
and the fixture copier, so the two cannot disagree about what they scan.

* fix(#3412): refuse to copy a fixture dependency outside the fixture root

copyScriptWithDeps resolved each relative require and joined the
repo-relative result onto fixtureRoot. A require resolving OUTSIDE the
repo yields a '../'-prefixed relative path, so path.join climbed out of
the fixture and wrote into the surrounding temp dir (verified:
repoRoot=/repo + depAbs=/etc/passwd wrote /tmp/etc/passwd).

No script in the tree does this today, so this closes an available
escape rather than an active one. Refuses via the existing unresolved-
require path so the failure names the offending specifier. Covered by a
negative proof that the guard fires and that nothing lands outside the
fixture.

* fix(#3412): parse requires instead of pattern-matching them; restore the foreign-prefix contract

Applies all findings from the second orthogonal review round, re-run
because real code changed after round 1.

HIGH (security) — extractRequires stripped BLOCK comments before LINE
comments, so a '//' comment containing '/*' opened a phantom block
comment, and a '//' inside a string literal truncated the line. Both
hid real requires: 'const u="http://x"; require("./real.cjs")'
returned [], and four real requires in gsd-core/bin/gsd-tools.cjs were
invisible. Replaced with a real AST parse via espree.

This is ADR-3212's own Decision 4 — tokenizer-first for stateful
grammars — applied to the case it describes; comment/string/regex
nesting is exactly such a grammar, which is why the regex version was
wrong. The function was moved byte-identical out of the #2858 packaging
guard, so the bug PRE-DATES this branch and has been a live blind spot
there: a shipped script could have required an unshipped path
undetected. Fixing it makes that guard strictly stronger than on next.

espree is promoted from a transitive eslint dependency to an explicit
devDependency rather than relying on hoisting. The script parse attempt
sets ecmaFeatures.globalReturn because Node wraps CommonJS bodies in a
function, making a top-level return legal — scripts/check-coverage-gate
.cjs relies on it, and without the flag the guard throws on a file it
is supposed to scan. Verified 0 unparseable across all 324 .cjs/.js
under scripts/, bin/, and gsd-core/bin/, and 0 new violations against a
real npm pack, so the exact extractor does not newly fail the guard.

MEDIUM (security) — the repo-containment check guarded dependencies but
not the entry path. One escapesContainment predicate now guards both.

LOW (security) — containment was lexical while fs follows symlinks, and
a directory symlink could mint a fresh dedupe key per level. realpath
now resolves both repoRoot and each dependency before the decision, and
the realpath-derived path is the dedupe key. Destination layout still
uses the original repo-relative path, so copied trees are unchanged.

MAJOR (standards) — the round-1 behavioral rewrite of phase-id tests
lost the foreign-prefix contract: every assertion was satisfied by an
impl returning [A-Z]+\x2d42, i.e. ANY project code — the exact #3599
bug class the exact-source prevents. The literal assertions it replaced
were catching this. Now asserts the compiled regex REJECTS a different
prefix with the same number.

MAJOR (standards) — the test hand-duplicated production's heading regex
with no parity guard (CLAUDE.md's 'Generative Fix Divergence'). Removed
the parallel surface instead of policing it: src/roadmap.cts exports
buildPhaseHeadingRegex, searchPhaseInContent calls it, the test imports
it. Byte-identical .source and .flags verified for both escaped forms.

MINOR — '..foo' no longer false-flagged as an escape; the inverted
spurious-vs-missing doc claim corrected; the dead allow-test-rule
header removed.

* chore(#3412): backfill changeset pr number to 3416

* fix(#3412): make the escape guard's own regex linear, reword an injection-scan collision

Two CI failures on PR #3416, both in code this branch added.

CodeQL js/redos (high) — REPLACE_CALL_RE's outer alternation let a
bracket run be consumed EITHER by the character-class branch OR one
character at a time by the trailing catch-all, so a failing match
explored both parses of every pair. Measured on the real regex:
n=26 -> 204ms, n=28 -> 791ms, n=30 -> 3475ms, a clean 2^n. This script
scans repo source, so a file with a long bracket run after '.replace(/'
would hang CI outright — a guard against undisciplined pattern
construction was itself the worst pattern in the diff.

Fixed the way ADR-3212 already prescribes: the catch-all branch now
excludes '[' and ']' so a bracket can only be consumed by the class
branch (this is what makes it linear), and every quantifier is bounded
(the locked bounded-quantifiers decision) as a second line of defense.
Now 0ms at n=2000. Disclosed coverage tradeoff, recorded at the
constant: a regex literal with a BARE unescaped ']' outside a class is
no longer matched by this backstop. No census shape has that form, and
the AST rule remains the primary detector.

Verified the guard did not go blind doing it: a real census-shape
violation is still reported, and an allow-adhoc-regex-escape
suppression comment is still honored.

Regression test drives the exported findViolations on a
2000-repetition adversarial input and asserts the RESULT. It makes no
wall-clock assertion — elapsed-time tests are forbidden — so a
regression surfaces as a harness timeout, which is the correct signal.

Prompt injection scan — 'must not act as a regex wildcard' in a test
comment matched the scanner's jailbreak pattern act\s+as\s+(a|an|if|
my). Reworded to 'behave as'. Deliberately NOT allowlisted: silencing a
whole test file over one phrase would blunt the scanner permanently,
and the comment has nothing to do with injection.

Neither failure was reachable from the remote runner — CodeQL and the
injection scan are not in that matrix, so the sha it passed was green
and still wrong.

77374cfc32 fix(#2528): resolve digit-leading phase directories by bare number (#2559)
* fix(#2528): resolve digit-slug phase dirs by bare number — tokenizer rewind, shared bare-integer fallback, resolution-path parity gate

extractPhaseToken welded 2-digit slug words onto the phase token (phase 10
named "24/7 Autonomy" -> dir 10-24-7 -> token 10-24), making digit-prefixed
phase names unresolvable by bare number across every phase verb.

- phase-id: continuation segments must be the PURE 2-digit zero-padded form
  the write side emits; a 1-digit terminator rewinds the absorbed run
  (10-24-7 -> 10) while >=2-digit terminators keep the locked #2232
  round-trip (14-06-2026-photos -> 14-06).
- phase-id: new matchPhaseDirs owner — primary exact-token match plus a
  bare-integer leading-digit-run fallback for shapes the tokenizer cannot
  rewind (05-80-20-cleanup); collisions stay #2237-loud.
- locator/find-phase/phase-plan-index all delegate selection to the owner;
  plan-index gains the previously missing multi-match guard.
- tests: #2528 unit + fast-check metamorphic blocks; new 9-scenario
  resolution-path parity gate across all three paths.

* fix(#2528): route the fourth resolution site through matchPhaseDirs

Review BLOCKER. smart-entry.cts::detectVerifyFailed resolved the current
phase's directory with its own `.find(phaseTokenMatches)` and never
reached the shared selection, so the bare-integer-fallback family the
issue names — `05-80-20-cleanup`, `30-12-factor-refactor` — resolved
nowhere. The miss is silent by construction: an unresolved phase reports
"not failed", which is byte-identical to a healthy one, so a failed
verification simply never surfaced in /gsd or /gsd:progress.

`entries` is already sorted and matchPhaseDirs filters without
reordering, so matches[0] reproduces the previous selection exactly
wherever the old code resolved at all.

Wiring it into phase-resolution-parity.test.cjs as a fourth path then
exposed a second, older defect in the same function: phaseTokenFromDirName
shape-probed the UNSTRIPPED token, so a project-code-prefixed directory
(`MEM-05-…`, tokenizing to `MEM-05-80-20`) failed the leading-digit test
and was dropped before any resolution ran — every phase in a
project-coded plan was invisible to this check. The probe now runs on the
stripped token; the returned value is unchanged, so the comparePhaseNum
sort is untouched.

Path 4 has no JSON surface to compare, so the gate observes selection
indirectly: plant the failing artifact in exactly one directory and a
passing one everywhere else, then read the boolean. Reverting either fix
turns 5 of the 10 corpus scenarios red.

* refactor(#2528): collapse the duplicated extractCanonicalPlanId

Review MAJOR. The function existed as two independent, byte-identical
copies — src/core-utils.cts and src/phase.cts — and this PR had to patch
BOTH with the same single-digit-slug rewind rule. That is the generative
fix divergence CLAUDE.md names, and only the core-utils copy was under
test, so a future one-sided patch would have silently split plan-id
canonicalization between the plan listing and everything else.

Removed rather than parity-tested: core-utils was already the leaf owner
and already exported it, and phase.cts already imported that module, so
there is no second surface left for a parity test to police.

* test(#2528): pin matchPhaseDirs at the digit-width boundaries

Review MAJOR. The bare-integer fallback's correctness rests entirely on
capturing each directory's whole leading digit run before the zero-strip
compare; a regex that stopped short would turn every query into a prefix
match, and "1" would claim 10, 100, and 12 alike. The existing coverage
was example-based and never touched that boundary.

Adds the explicit 9/10 and 1/10/100 cases — including the forms where
only the wider directories exist, so an exact-width neighbour cannot
satisfy the assertion — plus a fast-check property over arbitrary
distinct leading runs. The property is stated as an invariant on the
result (every returned directory's leading run IS the query) rather than
an expected list, so it covers primary and fallback matches alike and
cannot be satisfied by reimplementing the selection in the test.

Both fail when the fallback regex is degraded to a prefix match.

* fix(#2528): route the remaining eight consumers through matchPhaseDirs

phaseTokenMatches had eight consumers left that each rebuilt the directory
selection around it by hand: phases-list, next-decimal, phase-remove, the
W021 milestone-consistency check, schema-drift, the init-manager overview,
milestone-complete's disk check, and roadmap analyze. Every one of them
reproduced the reported symptom in full after the tokenizer was fixed.

None of them derives a displayed phase number from the matched directory,
so none needs phaseNumberForMatch; the change at each site is the
selection and nothing else. matchPhaseDirs filters without reordering, so
matches[0] reproduces the prior .find() choice wherever the old code
resolved at all.

phaseTokenMatches now has no call sites outside phase-id.cts. It stays
exported as the primitive matchPhaseDirs is built from and as a pinned
canonical surface, but no consumer reaches past the owner to it.

* test(#2528): extend the parity gate to the migrated consumers

Each of the eight is observed through the surface a user sees, not
through the matcher, with a no-directory control so the assertions cannot
be satisfied by a consumer that resolves unconditionally. init-manager
and roadmap-analyze are additionally asserted to agree with each other.

* refactor(#2528): own the case-flexible phase grammar and the leading-digit-run fragment

validate.cts derived its case-flexible regex sources by running
`replaceAll('A-Z', 'A-Za-z')` over two constants exported by phase-id.cts.
That passes lint-phase-id-drift.cjs — there is no literal copy of the
grammar — but it depends on the owner rendering that exact substring. The
day phase-id.cts expresses the same class any other way the replaceAll
silently no-ops and validate.cts narrows to uppercase-only. The failure
mode is a NON-match, so nothing throws and no uppercase-only fixture
notices. Both variants are now derived once, beside the sources they
widen, and imported.

Also names the leading digit run the bare-integer fallback selects on.
It was spelled `/^(\d+)(?:-|$)/` where the fallback filters and `/^\d+/`
where phaseNumberForMatch reads the number back off the winner; selecting
on one run and displaying another would resolve a directory and then label
it with a number that never matched it.

* fix(#2528): refuse to remove a phase when two directories claim its number

cmdPhaseRemove was the only migrated site taking matches[0] with no
multi-match guard. Every sibling resolution path returns ambiguous_matches
and refuses to choose; this one is the DESTRUCTIVE path, so choosing
silently is strictly worse than anywhere else. With 05-80-20-a and
05-90-till-late on disk, `phase remove 5 --force` deleted one of them and
renumbered every phase after it — where the base resolved nothing, deleted
nothing, and the corpus in tests/phase-resolution-parity.test.cjs already
declared that exact input ambiguous.

The refusal is emitted before any file is touched and carries both
candidates. CONSUMER_SCENARIOS could not express the case — every row is
binary, resolving to one directory or to none — so the gate gains a
dedicated ambiguous test. It asserts on the filesystem, not only on the
reported directory_deleted: a null printed after an rmSync would satisfy
every other check.

* fix(#2528): pair digit-leading phase directories with their roadmap phase in validate health

W006/W007 are the ninth site of this bug class and the one a
`phaseTokenMatches` grep could never surface: they resolve roadmap↔disk by
intersecting TOKEN SETS, which is a dir→token labelling rather than the
query→dir selection matchPhaseDirs owns. On the canonical fixture the
label is wrong in both directions at once, so `validate health` reported
"Phase 5 in ROADMAP.md but no directory on disk" AND "Phase 05-80-20
exists on disk but not in ROADMAP.md" for the same directory.

collectDiskPhases now keeps the directory names behind each token, so
W006 can ask the canonical matcher whether a roadmap phase resolves to a
real directory, and W007 — which iterates directories and therefore has no
query to resolve — gets the inverse mapping it never had: a directory is
claimed when some roadmap phase resolves to it.

Both checks are additive: the token intersection still decides every shape
it already decided, and the resolution can only REMOVE a warning. The
regression test carries controls in the other direction — a roadmap phase
with no directory must still raise W006, an unclaimed directory must still
raise W007 — so it cannot be satisfied by a check that stopped reporting.

* docs(#2528): state and pin the directory-side scope of the bare-integer fallback

The matchPhaseDirs docblock claimed deep-decomposition lookups were
untouched. That is true of the QUERY side only — no non-bare query enters
the fallback — but the DIRECTORY side is what changed classification: a
bare `5` now reaches a lone `05-01-auth` and resolves it (phase_number
"05", phase_name "01-auth") where the base found nothing.

The widening is irreducible from directory names alone. `05-01-auth`
(sub-phase 5.1) and `30-12-factor-refactor` (phase 30 named "12-Factor
Refactor") are the same `NN-NN-<slug>` shape, and the discriminator that
would separate them — "is the second segment a valid decimal sub-phase" —
accepts `5.1` and `30.12` equally. Any rule strong enough to exclude the
first excludes the second, which is the defect #2528 exists to fix. So the
tie is broken in favour of resolving, the docblock now says so, and the
consequence is bounded where it matters: two such directories are two
matches, and every caller (including phase remove) refuses to choose.

Pins both directions, since nothing observed the directory side before.

* fix(#2528): count surviving phases by identity in phase remove's STATE resync

#2640 landed on `next` while this branch was open. Its STATE.md phase-count
resync re-derives "which directory was removed" from the query with
`phaseTokenMatches`, which is the tenth site of this issue's defect: the
bare-integer fallback resolves `05-80-20-cleanup` for query `5`, but the
token predicate does not, so the just-deleted directory is counted as still
present and the written `Total Phases` is one too high.

`targetDir` already IS the directory that was removed, and the block is gated
on it being non-null, so identity answers the question exactly — which is also
what the comment above the filter already claimed it did. This keeps
`phaseTokenMatches` out of `phase.cts` rather than re-importing it to satisfy
one call site: the module's public surface should not grow for a question that
does not need re-derivation.

Pinned in the parity gate with a control on a directory the tokenizer reads
correctly, so the assertion is about the digit-leading shape and not about the
counting rule changing for everything.

* fix(#2528): let the resolution layer own the digit-leading slug family alone

The tokenizer rewind this fix carried — pop the last absorbed continuation when
the segment that stopped the scan is a bare single digit — reads
"10-24-7-autonomy" (phase 10 named "24/7 Autonomy") correctly and silently
re-reads "10-24-7-zip" (sub-phase 10.24 named "7-Zip Integration") from "10-24"
to "10". The two names are string-identical in shape, so no local signal
separates them; the rule traded the reported ambiguity for the symmetric one a
level down, on a 15-caller chokepoint whose output also feeds query-less
derivations (STATE.md phase counts, W007, the #2562 key surface). A well-formed
sub-phase directory became unresolvable by its own id — the very symptom #2528
was filed about.

It also bought nothing. The bare-integer fallback in matchPhaseDirs already
resolves "10-24-7-autonomy" for query "10" whatever the token is: no primary
match, bare query, leading digit run "10". The reported case was covered twice,
by two rules, and the two disagreed about the case nobody reported.

So the rewind is removed rather than narrowed, in the tokenizer and in the five
surfaces kept in lockstep with it (BRACKET_PHASE_TOKEN_SOURCE,
PHASE_TOKEN_FROM_DIR_RE, canonicalPlanStem's pair grammar and its collision
branch, roadmap-parser's numericRe, extractCanonicalPlanId), together with the
SINGLE_DIGIT_RUN_SEGMENT_SOURCE owner constant they shared. Disambiguation now
lives only where a QUERY exists to disambiguate against, which is the same
bounded mechanism the "05-80-20-cleanup" shape already used.

Measured, not argued: over 29800 generated directory names, extractPhaseToken is
byte-identical to `next` on every input except the lowercase-continuation class
("01-20a", "05-80-20-25abc") — a rule about the segment itself, not a guess about
its neighbour.

Both readings now stay reachable by their own ids:
  matchPhaseDirs(['10-24-7-autonomy'], '10')    -> the dir   (fallback)
  matchPhaseDirs(['10-24-7-zip'],      '10')    -> the dir   (fallback)
  matchPhaseDirs(['10-24-7-zip'],      '10-24') -> the dir   (primary)

* test(#2528): pin the one-continuation boundary the rewind had no coverage for

The regressing shape was invisible to the suite by construction, not by luck:
the deep-rewind property built its cases from `continuationArb` with
`minLength: 2`, so it never exercised the single-continuation case — exactly one
genuine sub-phase level before a digit-leading slug — and every hand-written
fixture used the ambiguous shape only where "phase-plus-slug" was the intended
reading.

`continuationArb` is now `minLength: 1` and the property states the invariant
instead of the old rule: for any prefix, phase, 1-5 continuations and any
one-digit terminator, the token equals the FULL continuation run on both the
imperative and the regex surface, and `matchPhaseDirs([dir], token)` returns that
dir. That third assertion is the one that catches the class on its own — the old
behaviour made a well-formed directory unresolvable by its own id, which is a
property, not a fixture.

Around it: "10-24-7-zip" and "10-24-3d-printer" now sit beside
"10-24-7-autonomy" everywhere the family is pinned, so the two readings can never
diverge again; the 24/7 metamorphic property asserts the RESOLUTION result rather
than the token (the token is precisely the part no surface may decide); the
end-to-end parity corpus gains "a sub-phase with a digit-leading slug resolves by
its full id" across all four resolution paths; and the milestone-scoping residual
is pinned in three directions rather than left to prose.

Mutation: re-inserting the rewind and rebuilding turns 9 tests red, the
`minLength: 1` property first, and nothing else. Build success checked separately
(build:lib reports 0 `error TS`), so the mutation reached the artifact under test.

* test(#2528): pin the #2946 guard against digit-leading phase directories

The #2946 fix makes the milestone-complete unstarted-phase guard run
unconditionally, so whether it fires now rides entirely on the
directory-resolution owner this PR replaces. Two cases, both with STATE.md
carrying no `milestone:` field so the #2946 path is the one exercised:

  - ROADMAP Phase 5, disk `05-80-20-cleanup` → guard must stay silent.
    RED on next (fail-closed: the guard blocks a legitimate one-way-door
    operation because phaseTokenMatches resolves neither 05 nor 80 for
    that directory).
  - ROADMAP Phase 80, same directory → guard must still fire. Green on
    both sides; it pins the fail-open direction against a future widening
    of the matcher.

* fix(#3175): stop the injection scanner reading RegExp.exec as code execution

The apostrophe fix in 27aa40f6 replaced ["\x27] with a real ["'] class.
The old class never contained an apostrophe at all (POSIX bracket
expressions do not honour backslash escapes, so it was the set ", \, x,
2, 7), so only exec(" matched. Single-quoted method calls now match for
the first time, and RegExp.prototype.exec takes a subject string, not
code: any PR touching a file that tests a regex goes red. On next, six
files match the scanner's own pattern across 16 method calls.

A plain [^[:alnum:]] boundary cannot separate the two forms because . is
not alnum, so exec gets [^[:alnum:].] and the command-execution vector
moves to a dedicated member-call pattern. Bare exec('rm -rf /'),
cp.exec(...) and child_process.exec(...) all still fire.

Mutation: reverting the boundary reds 1 test and only it; removing the
member-call pattern reds the 2 non-weakening tests and only them.

* fix(#2528): keep exec( detection receiver-blind, allowlist the two grammar suites

The left boundary [^[:alnum:].] added in 58a7b560 excluded a preceding dot,
which dropped every member-position .exec('…') from the scanner. The follow-up
receiver pattern only restored three literal spellings (child_process,
childProcess, cp), so require('child_process').exec('…') — the most common Node
spelling of the vector this pattern exists to catch — became invisible, along
with any opaque receiver (conn.exec, shelljs.exec).

Revert the pattern to its receiver-blind form and handle the RegExp.prototype
.exec false positive where the script already handles this class: per-file
ALLOWLIST entries for the two phase-token grammar suites. Mutation-checked —
removing the two entries reds exactly those two files and nothing else.

The four assertions written around the old patterns are replaced by a
table-driven set covering all six spellings, including the three the narrowed
pattern silently lost.

* docs(#2528): pin the three undeclared grammar edges, correct the ambiguity claim

Review round 10 asked for declaration, not behavior change, on four items. All
four have zero production consumers or preserve their caller's prior rule, so
each is pinned as a test or corrected in prose rather than reverted.

- BRACKET_PHASE_TOKEN_SOURCE: the (?=-|$) terminator is what keeps the bracket
  read path in step with the other surfaces, and it costs the display shapes
  (`05.03: Title`, `12A: X`, `05.03]` no longer tokenize). Pinned so widening
  the terminator class is a deliberate act rather than a lookahead deletion.
- canonicalPlanStem: uppercase plan suffixes still strip, lowercase and dotted
  sub-plans now fall through. Dead export; pinned as a decision on record.
- getMilestonePhaseFilter: `12A-01-foo` now yields `12A-01`, matching what
  `12-01-foo` has always yielded. The letter suffix was the only reason a
  sub-phase directory folded into its parent phase's milestone window; the two
  shapes now agree. Not named in the review — found auditing the same commit.
- matchPhaseDirs docblock claimed every caller refuses on multi-match. Four do;
  five take matches[0]. Replaced the claim with the actual two-tier policy and
  the honest caveat that the bare fallback makes multi-match newly reachable
  for queries that previously found nothing.

86bebcefa2 refactor(#3216): bind milestone identity to the canonical locator (#3226)
* refactor(#3216): widen milestone-window guard to literal-## matchers

The guard keyed only on the `#{N,M}` quantifier plus a literal version or
phase-lookahead token. getMilestoneInfo hand-rolls its milestone-heading match
with a literal `^##`/`## ` and an interpolated ${escapedVer}, so it satisfied
neither token and the guard reported a clean zero on a file carrying live
re-derivations (#3171, #3197) — a zero it did not earn.

Widen token (a) to a literal 2-6 `#` run, admitted ONLY inside a heading-MATCHER
literal (a regex literal, or a string/template handed to new RegExp) so a
heading-BUILDING template is not mistaken for a re-derivation. Widen token (b)
with the grouped `v(\d+(?:\.\d+)+)` shape and an interpolated version
placeholder.

Ships BEFORE the consolidation per ADR-3180 s7.2: a guard widened afterwards
measures an already-cleaned surface. It is expected to be RED until the
consolidation lands.

* test(#3216): failing-first milestone-identity single-owner suite

63 tests across two files, from the matrix in .gsd/phase/. Section H of
milestone-window-single-owner.test.cjs covers the 21 input classes of the
design's behavior table plus its negative space; milestone-window-drift-guard
covers the widened tokens and proves the exemption is function-scoped, not
file-scoped.

Copy count is 3 found by the guard, not 1 per the epic (ADR-3180 Amendment 3's
standing rule, holding for the fourth consecutive phase): both getMilestoneInfo
sites plus cmdRoadmapAnalyze's milestone enumeration at roadmap.cts:454, which
carries the same #3171 truncation and #3197 phase-heading confusion.

Expected RED until the consolidation lands.

* refactor(#3216): bind milestone identity to the canonical locator

getMilestoneInfo hand-rolled two milestone-heading regexes inside the owner's
own file. Both were wrong, differently: the STATE-version site's ^## anchor is
level-blind so [^\n]* absorbs a third #, and the fallback site had no anchor at
all, so '## ' matched from the second # of '###'. Against
'### Phase 7: Close v3.3 gaps' the fallback returned {v3.3, gaps} (#3197). Both
captured names with [^\n(], truncating at a parenthetical (#3171).

Bind both to the canonical grammar. locateMilestoneHeadings becomes a
version-filtered view over one shared source, and a new version-agnostic
listMilestoneHeadings enumerates milestone headings for callers that need all
of them. getMilestoneInfo returns ScopedResult<MilestoneInfo|null>; the
{v1.0,'milestone'} default, which was output-identical to a real v1.0 project,
is deleted. The #2245 never-throws invariant is preserved.

Copy count: 3 found by the guard, not 1 per the epic. The third was
cmdRoadmapAnalyze's own milestone enumeration (roadmap.cts:454), carrying both
defects in the implementation the epic blessed.

buildStateFrontmatter and archivePhaseDirectories branch on scope: the first
writes null rather than a fabricated identity, the second falls through to its
dated-label fallback. A fabricated v3.3 passes ARCHIVE_VERSION_LABEL_RE, so it
would otherwise misfile phase history.

Also fixes an unsafe cast in init.cts that masked these type errors across five
call sites, which would have shipped undefined milestone fields under green tsc.

* fix(#3216): restore the #1761 unbounded guard and bullet precedence

Review and the first full-matrix run surfaced five real defects in the
consolidation, all fixed here rather than by relaxing the tests that caught
them:

- buildStateFrontmatter gated its isMilestoneBoundedInRoadmap check on the
  scope-gated milestone value, which is null on any non-COMPLETE scope, so the
  #1761 unbounded guard was silently skipped and state json reported a percent
  it must omit. It now gates on the STATE-asserted version, independent of
  identity scope.
- The rewrite lost #2135's precedence: the name-bearing progress-marker bullet
  is consulted before the heading again.
- A single-segment version (v3, no dot) did not resolve; the name-extraction
  fallback now accepts it.
- A version carrying regex metacharacters, or a $& / $1 replacement pattern,
  is matched literally.
- listMilestoneHeadings' heading field trimmed, so a CRLF roadmap no longer
  leaks a trailing carriage return into roadmap analyze's output.

Also emits milestone_version / milestone_name / current_milestone as explicit
null rather than omitting the key, so the prompt layer cannot render a bare
placeholder, and corrects an init.cts comment plus a cast left inconsistent.

* test(#3216): update milestone-identity expectations to the scoped contract

getMilestoneInfo returns ScopedResult<MilestoneInfo|null> and the
{v1.0,'milestone'} default is deleted, so the suites asserting the old shape
assert removed behavior. Updated rather than weakened: every touched call site
now asserts the scope explicitly against the frozen SCOPE enum.

roadmap-parser.test.cjs: 20 expectations moved to {value,scope}. The #1881
unreadable-vs-absent diagnostic assertions are untouched and still prove their
original point — only the return shape moved. One pre-existing assert.ok(info)
is now a specific UNSCOPED assertion, so that case is stronger than before.

new-milestone-clear-phases.test.cjs: the test asserting phases clear archives
under the v1.0 default now asserts the dated archived-<YYYYMMDD> fallback,
which is the deliberate consequence of deleting that default.

Two of this branch's own tests were also corrected after they drove the
implementation the wrong way: the parity test compared raw heading text and so
pushed a stray ## prefix into roadmap analyze's public output, and the hostile
metacharacter row demanded a pathological version resolve, which pushed a
widening of the ADR-locked \b boundary. Both now assert what the contract
actually requires.

* docs(#3216): document milestone identity and correct the CONTEXT.md entry

ADR-3180 s7.2 moves to Enforced and gains two rules that were unstated: the
name derives from the heading's own version token and drops a trailing status
marker, and a free-form legacy ROADMAP with no version anywhere is UNSCOPED
with no identity rather than a defaulted v1.0 (decided by the maintainer before
implementation, per s7's own rule that an unstated behavior is not decided).
Amendment 4 records Phase 6's validation, including that the copy count was a
lower bound for the fourth consecutive phase.

CONTEXT.md's Roadmap Parser entry described locateMilestoneHeadings as
boundary-matched with (?![\w.-]) — the alternative Amendment 2 tried and
REVERTED. The code uses \b and says so, and the ADR agrees; the revert updated
code and ADR and missed CONTEXT.md, which is the epic's own fixed-on-one-copy
failure class in the docs layer, on a file that is itself a PR gate.

* fix(#3216): persist the real version on a truncated identity

buildStateFrontmatter wrote null for BOTH milestone and milestone_name on any
non-COMPLETE scope, discarding a real version. ADR-3180 s7.2 rule 6: a version
known with no resolvable name is TRUNCATED carrying {version, name: null} —
'the version is a real answer, the name is a non-answer, and collapsing the two
is the failure this contract exists to prevent.'

The two fields are now gated by what is actually known: the version whenever one
exists (COMPLETE or TRUNCATED), the name only on COMPLETE. Never fabricated.

Caught by this phase's own Decision 4(c) consumer-output test, which is the
argument for asserting at the consumer rather than the owner — the owner was
correct throughout; only the consumer collapsed its answer.

* refactor(#3216): extract helpers and make cmdCommit's scope gate explicit

From the two-axis code review:

- init.cts repeated the identical getMilestoneInfo cast at five sites with
  copy-pasted comments — duplication inside a PR whose thesis is that duplicates
  get deleted. Extracted milestoneRecord(cwd); the one site-specific comment is
  kept, the four generic copies removed.
- getMilestoneInfo hand-built its { value, scope } literal at ten return points;
  a local scoped() constructor now does it once. Every per-branch rationale
  comment is preserved and no returned value or scope changed.
- cmdCommit gated the milestone branch name on plain truthiness, which is also
  true for TRUNCATED, so an unresolved identity drove branch creation
  incidentally rather than deliberately. It now gates on the SCOPE enum,
  accepting COMPLETE or TRUNCATED because both carry a real version, and the
  comment records why that differs from archivePhaseDirectories — which demands
  COMPLETE because it uses the value as a filesystem path component.

* test(#3216): cover the bare-version-in-prose truncated path

The spec review found the bareVersionMatch path — no STATE version, no
milestone heading, a version token only in prose — returning TRUNCATED with no
test exercising that exact shape, violating Decision 4's boundary-coverage
requirement.

* docs(#3216): record the missed Tier-2 surfaces and rule 5's corollary

Decision 3 requires an explicit call-out for EVERY Tier-2 change, and Amendment
4's first draft named eight surfaces while the change touched thirteen. Adds
cmdCommit's branch-name construction and the four init JSON bundles, an
incomplete list being the same defect in miniature that this epic removes.

s7.2 rule 5 gains a corollary separating two cases the original wording ran
together: no version token ANYWHERE is UNSCOPED, while a bare version token in
prose or a non-milestone heading is weak but real evidence and yields TRUNCATED
under rule 6.

636ec92107 refactor(#3185): phase enumeration has one owner and a decidable scope (#3222)
* test(#3185): failing-first phase-enumeration single-owner suite

Covers the enumeration rows with direct code evidence: 999.* backlog dirs
listed by progress/stats, the phase-0 sentinel divergence, the #1324
letter-prefixed-decimal negative space, and the destructive-path find —
cmdPhasesClear carries a fifth sentinel copy (/^999(?:\.|$)/) that excludes
999 but not 0, so a 0-* directory roadmap.analyze preserves is deleted there.

Also covers the pass-all degrade, which is where the defect actually lives:
when the milestone window declares no phases the filter becomes a literal
() => true and its heading-side sentinel exclusion is unreachable. A fixture
carrying phase headings keeps the filter active and never reaches that path.

Named for the derivation, not a module: the suite drives commands, phase,
milestone, workstream-inventory and state, and both the phase and
phase-locator buckets are already at the per-module test-file cap.

Committed alone so the remote runner records the failure before the fix.

* refactor(#3185): phase enumeration has one owner and a decidable scope

Adds phase-locator.cts::listMilestonePhaseDirs as the single canonical owner
of "which phase directories belong to the current milestone". It applies the
milestone window AND the sentinel filter and returns a ScopedResult, so a
caller can tell a genuinely-empty milestone from an enumeration that could
not be scoped.

The sentinel test now runs against DIRECTORY NAMES and is unconditional.
getMilestonePhaseFilter excludes sentinels from its ROADMAP heading set, but
degrades to a literal () => true pass-all predicate when that set is empty --
at which point the heading set is never consulted and its sentinel exclusion
is unreachable exactly when it is needed. That degrade is the #3167 path, and
it is why stats already used the filter and still listed backlog directories.
The narrowing is sentinel-only: pass-all stays over-inclusive otherwise.

Sentinel copies deleted, canonical isSentinelPhaseId adopted:
  - cmdRoadmapAnalyze's local closure (parseInt === 0 || === 999), 2 call sites
  - cmdPhasesClear's /^999(?:\.|$)/ -- the DESTRUCTIVE path, which excluded
    999 but not 0, so a 0-* directory roadmap.analyze preserves was deleted

cmdStats also seeded rows from ROADMAP headings with no sentinel filter, so a
999 heading produced a row with no directory; that seed is filtered now.

cmdPhasesList routes only its ENUMERATION. --phase lookup searches the
physical set (scoping it would report an out-of-window phase as not found) and
--include-archived still merges archived dirs (they are by definition from
other milestones). Both exempt by documented reason, never a file allowlist.

Fixed inline, found while building: isDirInMilestone could not match a #1324
letter-prefixed-decimal directory (P0.0-foundation) to its own Phase P0.0
heading, so stats reported the phase with plans: 0 while its directory held
plan files. Defers to phase-id's extractPhaseToken rather than widening a
fourth bespoke regex; additive, so it can only admit directories.

* refactor(#3185): route the last two enumeration re-derivations

workstream-inventory countRoadmapPhases counted every `Phase` heading across
the whole ROADMAP -- no window, no sentinel filter -- so it counted 999.*
backlog and Phase 0 and spanned every milestone the document ever had. Its own
caller already resolved a currentVersion and passed it to getMilestonePhaseFilter
elsewhere in the same file; this was the sibling copy that never got the fix.

state.cts phaseInventoryProvider enumerated phase dirs with its own
/^(\d+)-(.+)$/ convention regex and neither filter, so a rebuilt STATE.md
inventory carried backlog and sentinel directories as current-milestone phases.
A non-COMPLETE enumeration scope now throws to the outer catch as a real scan
failure rather than reporting a confident undercount, mirroring the per-phase
scanPhasePlans contract beside it.

* refactor(#3185): consolidate 23 sentinel re-derivations onto one predicate

The whole-repo drift guard (ADR-3180 Decision 4a, no file allowlist) found the
sentinel rule re-implemented 23 times across 8 modules, in three regex variants
plus four integer-comparison forms. Most tested 999 only, so Phase 0 slipped
through them while roadmap.analyze and the engine-wide convention (#1580) both
treat 0 and 999 alike. That disagreement is the defect class this epic removes.

All 23 now call phase-id's isSentinelPhaseId (SENTINEL_RANGES [0,999]). Sites:
init recommended-actions and backlog counts, milestone phase scan, the
phase-lifecycle progress table, phase.cts used-number collection and the four
renumber-on-remove guards, roadmap-parser's heading and bullet milestone
counts, roadmap get-phase fallbacks, and state's heading denominator.

Excluding Phase 0 at these sites is a deliberate behavior change and the point
of the consolidation — several carried comments already saying 0 should be
excluded while the literal beside them caught only 999.

Adds scripts/lint-phase-enumeration-drift.cjs, wired into lint:ci. It scans the
whole src/ tree with no file allowlist and reports both shapes: an independent
phases-dir enumeration, and an independent sentinel literal. Exemptions are
function-scoped with a written reason. The guard is comment-aware — its first
pass flagged JSDoc and a comment documenting that the code below uses the
canonical owner, which would have trained readers to exempt prose.

* refactor(#3185): resolve every phases-dir enumeration; drift guard reports zero

Per-site triage of the 31 remaining whole-repo guard hits, applying the rule
generalized from #3183's Amendment 1: a LOOKUP, DIAGNOSTIC, ARCHIVAL or
MUTATION pass wants the physical set; only "which phases belong to this
milestone" wants the scoped set.

Routed (10): init new-milestone phase_dir_count, init milestone-op fallback
count, init manager, init progress, milestone complete stats/dry-run/archive
move, phase complete's next-phase scan, state update-progress, state
frontmatter stats, and uat audit's active set.

Exempt with a written function-scoped reason (never a file allowlist): the
audit/UAT/verification sweeps that deliberately scan every directory to report
gaps, phase create/insert/rename/renumber mutations, single-phase lookups,
roadmap-upgrade's cross-milestone migration, cmdPhasesClear's whole-tree
destructive pass, and the reads that list a phase dir's FILES rather than
enumerating the phases dir at all.

Latent defects fixed by the routing: sentinel directories leaked into
cmdInitNewMilestone's phase_dir_count, cmdMilestoneComplete's stats, dry-run
AND ARCHIVE MOVE, cmdStateUpdateProgress, buildStateFrontmatter and
cmdAuditUat's active set — every one of those hand-rolled an isDirInMilestone
filter with no sentinel exclusion, so `milestone complete` was archiving
backlog directories.

scripts/lint-phase-enumeration-drift.cjs now reports 0 re-derivations and
npm run lint:ci is green.

* fix(#3185): wire scope to consumers; revert two wrong routings the suite caught

Review + remote runner findings, all fixed:

The three consumers computed the enumeration scope and threw it away, so
TRUNCATED/UNSCOPED/UNREADABLE collapsed into the same output as COMPLETE --
reproducing this epic's own output-identical-failure defect one layer up.
progress, stats and phases list now emit phase_scope (null on the phases list
--phase lookup path, which performs no enumeration).

Two routings were wrong and the suite proved it:

roadmap-parser's two milestone phase-count scans are reverted to the 999-only
literal. isSentinelPhaseId is BROADER than what it replaced: its legacy branch
runs /^0*(\d+)/ over "00.1", which backtracks to capture 0, so it read #2554's
decimal phase ids as sentinel milestone 0 and stopped counting them.

state.cts phaseInventoryProvider is reverted to the physical disk scan.
`state rebuild` is a RECONCILIATION pass -- scoping it made it throw on healthy
trees whose fixture resolves no window, swallowed the raw readdirSync fault
message #3057 B1 requires verbatim, and stopped it dropping orphan STATE.md
rows, which is the job.

Both are now function-scoped guard exemptions with written reasons, not
silent reverts. This is the consolidation trap named in the epic: a canonical
rule can cover MORE than the copy it replaces, and only real inputs show it.

Adds phases list coverage, a scope-branch test, and a drift-guard unit suite;
backports comment-awareness to the milestone-window and plan-count guards so
all three siblings share one false-positive profile; names #3161 alongside
#3167 in Amendment 3's subsumption record.

* fix(#3185): correct isSentinelPhaseId's decimal-zero misclassification

An isolated security review caught this branch committing the epic's own sin:
the over-broad predicate was worked around at ONE call site and left live at
the destructive ones.

isSentinelPhaseId's legacy branch ran /^0*(\d+)/, which backtracks so any id
whose leading digit run is all zeros before a non-digit captures 0 -- "0.1",
"00.1" and "0.2554" all read as sentinel milestone 0. Two pinned contracts
disagree with that: #2554 requires "00.1" to be counted as a real phase, and
the 999 icebox is a whole reserved milestone so "999.1" must stay sentinel.

The rule is asymmetric and now says so explicitly: 999 is sentinel with or
without a decimal part; 0 is sentinel only when bare. A decimal phase under
either is a real phase for 0 and reserved for 999, because 999 reserves a
MILESTONE while 0 reserves a PHASE.

Fixing the owner lets the earlier workaround go: getMilestonePhaseFilter's two
scans route through isSentinelPhaseId again and the guard exemption that
existed only to accommodate the defect is deleted. The state.cts cmdStateRebuild
exemption stays -- that one is a genuine reconciliation-wants-the-physical-set
case.

Also corrects tests/adr-612-bracket-grammar.test.cjs, which asserted
isSentinelPhaseId('0.1') === true and so had encoded the defect as expected
behavior.

* fix(#3185): keep isSentinelPhaseId's semantics — 0.x is layered, not wrong

Reverts the previous commit. The remote suite failed six tests proving it
wrong, and the reason is the sharpest finding of this phase.

An isolated security review observed that isSentinelPhaseId reads 0.1 and 00.1
as sentinel milestone 0 and judged that a defect against #2554. Correcting the
canonical predicate broke #2949. Both contracts are pinned and both are right,
because they ask different questions:

  #2554  is this dir part of the current milestone's phase SET?  -> count 00.1
  #2949  must this phase COMPLETE before the milestone closes?   -> 0.x sentinel

No single global predicate answers both. isSentinelPhaseId keeps its semantics
(0.x IS a sentinel, #2949), and the milestone-window layer keeps a narrower
999-only rule (#2554) as a function-scoped guard exemption with a written
reason — not a second silent copy.

That corrects how Decision 1 reads: "one owner per derivation" governs who
computes an answer, not how many questions share it. An over-broad canonical
rule is as much a defect as a divergent copy and fails worse, because it looks
like consolidation. Recorded in Amendment 3 as the lesson for Phases 4 and 5.

Where a review's inference about intent conflicts with a pinned contract, the
pinned contract wins; the finding is adjudicated, not fixed.

The boundary tables in the enumeration suite are corrected to assert 0.x IS a
sentinel, with the layering explained.

* refactor(#3184): milestone windowing routes through one owner

Three copies of the milestone section-end walk lived in roadmap-parser.cts —
two distinct computeSectionEnd function nodes plus an inline third in
getMilestonePhaseFilter's versionOverride branch. computeMilestoneSectionEnd is
now the sole owner and the other two are deleted, not kept in sync by comment.

The whole-repo drift guard found what the epic did not: state.cts held three
more re-derivations of the same vocabulary — two byte-identical milestone
bounding checks carrying a defect neither reported copy has (no boundary after
the version token, so v2.0 matched inside v2.0.1), and a milestone-sectioning
predicate. All three route through the owner now.

A composition-level duplicate appeared inside this change's own first pass:
getMilestonePhaseFilter and cmdMilestoneComplete each re-assembled a window out
of the owner's primitives, and had already diverged on whether to skip a closed
milestone heading. sliceMilestoneWindow is the one composition.

Windows now carry the ADR-3180 SCOPE discriminator, so a truncated window is
distinguishable from a genuinely empty milestone — those were output-identical,
which is the whole failure class. roadmap analyze emits it (#3165), and
milestone complete refuses to archive on anything but COMPLETE rather than
pass-all moving every phase directory on disk (#3166). The pass-all degrade is
preserved where its premise holds: making the filter deny-all would trade a
silent over-inclusive answer for a silent under-inclusive one on the read paths
that count with it.

extractCurrentMilestone keeps its signature — 200+ affected symbols across 41
files and 25 process flows — and is a one-line wrapper over the scoped owner.

* fix(#3184): fence-aware phase detection and one heading-selection owner

Review fixes from the two orthogonal passes.

The blocker: hasPhaseEntries matched ATX phase headings fence-aware via
tokenizeHeadings but tested the #2199 bullet form against un-stripped markdown,
so a fenced EXAMPLE of the bullet syntax counted as a real phase. A genuinely
empty milestone then classified TRUNCATED and milestone complete refused a
legitimate archive — a false positive in the destructive direction, worse than
the defect this phase set out to fix. Both that path and getMilestonePhaseFilter
own pre-existing bullet scan now run on stripFencedCode, since leaving one meant
the owner file gave two different answers to the same question.

The selection rule — locate, prefer the non-closed heading, else the first — had
been written three more times inside the file whose thesis is single ownership.
selectMilestoneHeading owns it; all three sites route through it. The copies were
behaviorally identical, so this is de-duplication with no observable change,
verified by probing that all three paths select the same heading.

roadmap analyze emitting a scope no consumer read left #3165's actual symptom
alive, so Route 0 in next.md now treats a non-complete scope as scan-failed
rather than as a clean empty scan, and the ADR amendment no longer overstates
what shipped.

Also: the scope refusal moved above the archive-directory create, so a refusal
leaves nothing on disk; the versionOverride comment names all four consumers;
COMMANDS.md documents the new guard beside its sibling.

* test(#2658): exclude the changelog from the malformed-path scan

The gate walks every emitted .md/.js/.cjs file in an installed tree and asserts
none contains `.claude/.trae/rules` or `.trae/.trae/rules`. CHANGELOG.md ships
into that tree, and its #2658 entry quotes both malformed paths while describing
the fix that removed them — so the release note documenting the fix trips the
fix's own regression test. Red on next before this branch.

The installer is correct: a probe over a real --trae --local install found 621
emitted files, exactly one hit, and it was gsd-core/CHANGELOG.md. The scan scope
was the defect, not the product.

Excluded by exact relative path rather than by loosening the patterns or skipping
all markdown — the emitted agent and command markdown is precisely what #2658 was
about, so the gate stays strong everywhere it matters.

* test(#3184): regenerate install-tree fixtures for the shared drift scanner

scripts/lib/ ships in the npm package and installer, so extracting the shared
tree-walk into scripts/lib/drift-scan.cjs adds one path to every runtime's
install tree. Regenerated via npm run gen:install-tree; the delta is exactly
that one path per fixture.

The two drift guards themselves do not ship (scripts/lint-*.cjs is excluded),
so only the extracted library moves. This matches the existing
scripts/lib/allowlist-ratchet.cjs precedent, which is likewise a lint-only
helper carried in the shipped tree.

* fix(#3184): restore the #730 sub-milestone boundary and narrow the refusal

The remote runner caught two regressions this branch introduced. Both were mine,
and neither review pass found them — only running the existing suite did.

The version-token boundary. I replaced locateMilestoneHeadings' \b with
(?![\w.-]), reasoning that v2.0 matching inside v2.0.1 was the same defect #2562
fixed in isMilestoneShippedInRoadmap. It is not the same question. A milestone
state of v8.0 legitimately selects the '## v8.0-B' sub-milestone section over a
closed v8.0-A sibling (#730), and \b is what allows it while the stricter
boundary forbids it — nine tests in roadmap-phase-fallback said so. Reverted to
\b; the state.cts consolidation is now a straight merge with no behavior change,
and the v2.0/v2.0.1 ambiguity is left exactly as it was. The ADR amendment and
the design doc no longer claim otherwise.

The refusal scope. I refused whenever the window was not COMPLETE, but #3166 is
about the TRUNCATED window specifically — the heading is found and the section
closes before the phase region, so pass-all archives everything. UNREADABLE and
UNSCOPED are pre-existing, legitimately handled states, and refusing on them
broke 'handles missing ROADMAP.md gracefully' and three archive tests. Narrowed
to TRUNCATED; docs corrected to match.

One of the new tests was also wrong: its fixture gave the shipped and current
milestones' phases the same numeric id, and the filter matches on that id, so it
could not have distinguished the two windows. Fixture corrected to exercise what
it claims to.

* fix(#3184): enumerate drift-scan.cjs for uninstall

The installer copies scripts/lib/ wholesale, but uninstall removes an explicit
set — deliberately, so a user's own helpers in that directory survive. The
extracted drift-scan.cjs was copied in and never enumerated, so it outlived
uninstall, left the directory non-empty, and the rmdir that follows failed.

Added to GSD_SCRIPTS_LIB_FILES, following allowlist-ratchet.cjs, which is
likewise a lint-only helper that ships there and is enumerated. Verified with a
real install-then-uninstall into a temp target: scripts/lib/ held exactly the
three GSD files and was gone afterwards.

* test(#3184): assert install and uninstall agree on scripts/lib and scripts/changeset

Found while shipping this phase, and fixed here rather than noted.

install() copies scripts/lib/ and scripts/changeset/ into the target WHOLESALE —
the comment at the copy site literally says "and any future lib helpers".
uninstall() removes them by hardcoded enumeration, deliberately, so a user's own
helpers in those directories survive. A wholesale writer paired with an
enumerated remover cannot stay in sync by construction: any file added to either
directory ships to every user and is then orphaned in their repo forever, since
it survives uninstall, leaves the directory non-empty, and the rmdir that follows
fails. Nothing reported this. 31,225 tests were green over it.

That is the same divergence class this epic exists to delete, sitting in the
installer, so it gets the same remedy CLAUDE.md prescribes for it: a parity
assertion that fails the moment the two surfaces disagree. The test compares each
directory's real contents against its enumeration and names the offending file
plus the constant to add it to.

Both enumerations are hoisted to module scope and exported, so the test asserts
on the actual arrays rather than pattern-matching the installer's source — no
allow-test-rule annotation needed. Proven non-vacuous both ways: empty diff on
the current tree, correct report when an unenumerated file is injected.

scripts/changeset/ turned out to carry the identical defect and is covered too.

343835facc refactor(#3183): route live-plan counting through scanPhasePlans (#3199)
* refactor(#3183): route live-plan counting through scanPhasePlans

scanPhasePlans becomes the sole owner of the live-plan derivation. Twenty-one
independent re-derivations across seven modules now route through it, and
scripts/lint-plan-count-drift.cjs reports zero, scanning the whole repo rather
than an allowlist (ADR-3180 Decision 4a).

The epic scoped this at three copies. A whole-repo guard found twenty-six sites
across nine files, so Phase 1 absorbs every live-plan re-derivation and Phase 3
narrows to window plus sentinel enumeration.

Two sites are exempt with a documented reason rather than a bare allowlist:
audit.cts scans one quick task's own directory for a single completion record,
and gsd2-import.cts reads a foreign GSD-2 tasks/ layout during a one-time
import. Neither is a phase directory.

scanPhasePlans gains allPlanFiles (pre-supersession) alongside planFiles so one
owner answers both questions: verify.cts's numbering-gap check wants every plan
on disk, its pairing check wants the live set. Both fields are additive.

Highest-severity fix: cmdPhasePlanIndex, which feeds execute-phase wave
scheduling, was scheduling status:superseded plans into waves and reporting zero
plans for the post-#3139 nested layout.

filterPlanFiles and filterSummaryFiles are deleted; getPhaseFileStats orphaned
them and only their own tests still called them.

New leaf module src/planning-scope.cts carries the frozen SCOPE discriminator,
with its six-gate ripple closed: gitignore, inventory manifest, INVENTORY.md and
the CONTEXT.md glossary.

* docs(#3183): amend ADR-3180 for the Phase 1/3 boundary re-slice

The contract held; the phase boundary did not. The whole-repo drift guard found
26 re-derivations across 9 files against the epic's estimate of 3, and
cmdProgressRender re-derives both enumeration and plan counting on adjacent
lines, so DW4 was unsatisfiable within Phase 1's original file scope.

Records the amended scope, scanPhasePlans's new allPlanFiles field,
findOrphanSummaries, the two documented exemptions, the re-derived Tier-2
table, and the describeNonCanonicalPlans trap for later phases.

* fix(#3183): complete the canonical pairing rule and gate the naming diagnostic

The remote runner went red with 13 deterministic failures on both lanes,
and they were right: replacing verify.cts's canonicalPlanStem pairing with
summaryCandidates dropped a case the bespoke rule covered. A plan carrying a
descriptive slug after its id (68-01-scaffolding-PLAN.md) pairs with its
canonical-stem summary (68-01-SUMMARY.md), and summaryCandidates generated no
such candidate, so the plan read unsummarized.

The fix is to complete the one rule rather than restore a second:
summaryCandidates gains a canonical-id candidate, narrowed to fire only when an
id pair was actually extracted. countMatchedSummaries, findUnsummarizedPlans
and findOrphanSummaries all inherit it. The two-plans-one-summary collision
behaviour of the original rule is preserved deliberately and documented in
place.

Second defect, independently root-caused while verifying: routing the #2893
naming diagnostic through scanPhasePlans exposed it to the loose /PLAN/i
fallback, which is correct for counting and wrong for a naming check — a
non-canonically-named file was accepted as a valid plan and the diagnostic
went silent. cmdPhasesList, cmdFindPhase and cmdPhasePlanIndex now intersect
with a strict isCanonicalPlanFile predicate before reporting names.

Same class as the describeNonCanonicalPlans trap already recorded in ADR-3180:
a question about file naming wants the physical, strictly-matched set; only a
question about outstanding work wants the live set.

tests/repo-invariants.test.cjs asserts every bin/lib/*.cjs is linted xor
ignored per its ADR-457 migration state. The new planning-scope module closed
five of the six .cts ripple gates - gitignore, inventory manifest, INVENTORY.md
and the CONTEXT.md glossary - but not eslint, because that one is enforced by a
test rather than by lint:ci, so the local pipeline stayed green while it was
missing.

linted, matching every other migrated module.

* fix(#3183): replace the plan-count drift detector with a literal tokenizer

CodeQL reported 4 high-severity js/redos alerts on REGEX_LITERAL_MD_RE, the
backtracking regex that finds "a regex literal mentioning PLAN/SUMMARY and an
escaped \.md". Five review rounds found it had two defects, not one:

  - EXPONENTIAL, then CUBIC. Its "any char" atom `(?:\\.|[^/\r\n])` let a `\.`
    pair be consumed either as one escape or as two class characters, which is
    exponential backtracking: 27,464ms on `"/\.mdplan" + "\.".repeat(28) + "X"`.
    Excluding `\` from the class killed that but left a cubic path — 23ms at
    N=200, 172ms at N=400, 1362ms at N=800 on `"/" + "PLAN\.md".repeat(N)` with
    no closing `/`. This guard is the last stage of `npm run lint:ci`, which CI
    runs on fork pull requests, so a crafted src/*.cts could stall the job.
  - A DETECTION HOLE. A character class holding a bare, unescaped `/` — e.g.
    `/SUMMARY[^/]*\.md$/`, an ordinary path-excluding filter — terminated the
    literal at that `/`, so the scan never reached `\.md` and the guard missed
    it entirely. (Classes holding an ESCAPED `\/` were already matched; the
    tests cover those separately as parity, not as regressions.)

Both defects have one root cause: regex-literal grammar — `\x` escapes, and
`/` inside `[...]` not terminating — is not expressible in a backtracking
regex. So the detector is now a tokenizer, not a regex.

readRegexLiteralAt reads the literal at a given `/` in a single left-to-right
pass with no backtracking, treating escapes as two-character units and
suppressing the `/` terminator inside a character class. findRegexLiteralMdMatch
restarts it at every `/` on the line, preserving the old "find anywhere"
behaviour; MAX_REGEX_LITERAL_LEN (400) bounds each read — including the
trailing-flag scan — which keeps the whole-line cost linear.

Results: cubic shape flat at 0.06-0.39ms out to N=3200 (25KB), exponential
shape 0.01ms at 28 reps and 0.00ms at 64, and the bare-`/` class shapes are now
caught. Differential against the old regex over 28,474 lines (those matching
FILENAME_TEST_RE but not PLAN_SUMMARY_LITERAL_RE, across src/tests/scripts/
gsd-core/bin/eslint-rules, excluding 265 lines with >6 backslashes on which the
old regex hangs): 6 differences, all the tokenizer returning the fuller or
newly-correct literal, 0 old-only misses. The `\.md` token stays
case-insensitive, matching the `/i` the old regex carried.

Also closes three holes in the same new file:

  - walk() tested entry.isFile(), false for a symlink, so a symlinked
    src/*.cts was silently unscanned — an evasion of a guard whose stated
    principle (ADR-3180 Decision 4a) is whole-repo discovery with no allowlist.
    It now resolves symlinks, but confined: file links must resolve inside the
    repo root, directory links inside the scanned dir itself. Every sibling
    drift guard in scripts/ uses the Dirent classification and never follows
    links, so following them unconfined would have made this the only linter
    able to read outside the tree — on fork PRs an arbitrary out-of-repo read
    whose matched fragments reach a public CI log. The narrower directory rule
    additionally stops `src/up -> ..` from sweeping the whole repo, and the
    skip list is now checked against resolved paths so `src/g -> ../.git`
    cannot reach .git/** or node_modules/**. Real paths are de-duplicated and
    files reported canonically, so a symlink alias cannot shift which
    FUNCTION_SCOPED_EXEMPTIONS key applies.
  - Both the reported fragment and the reported FILE PATH are attacker-
    controlled source text written straight to a CI log, and git permits
    control bytes in a filename. Both are now escaped — C0/C1/DEL plus the
    bidi and zero-width controls — so a crafted literal or filename cannot
    recolour the log, overwrite a line with CR, or fabricate a line that looks
    like this guard's own success output.

Regression coverage in tests/plan-count-single-owner.test.cjs: a child-process
probe over both pathological shapes (catastrophic backtracking is synchronous
and would freeze the suite rather than fail one test), the bare-`/` class
shapes verified to fail against the parent-commit blob, root-confinement tests
covering the outside-file, outside-directory, cycle, broken-link and duplicate
cases, direct isInsideRoot coverage including the sibling-prefix case that a
bare startsWith would let through, sanitizeForReport coverage, and
limit-1/limit/limit+1 coverage of MAX_REGEX_LITERAL_LEN derived from the
exported constant. The earlier structural assertion was dropped — it checked
for the substring `[^/`, which respelling the class as `[^\r\n/]` defeats
while staying exponential.

0e6fa2e2cf enhance(#3118): close the dead injectables and the shell projection follow-on — Wave 4 (#3124)
* test(#3118): failing-first coverage for the dead injectables and the shell projection

Adds the counter-tests Wave 4 closes against, before any fix:

- antigravityWatermark had zero test references. The four existing tests
  that look like watermark coverage hand the fallback a literal mark and
  never call the producer, so nothing pinned whether a real run's mark is
  correct. Covers all six branches plus the non-object cache classes.
- Pins the fail-open: a transcript read that throws reports lines:0,
  indistinguishable from a genuinely empty transcript, and the consumer
  then replays a previous run's review as this run's.
- Pins the export-line escaping across the repair, persist and win32 bash
  lanes, including the parity assertion that they must not diverge.
- sliceCurrentPositionSection: empty-vs-absent, fenced heading, second
  occurrence, H3, CRLF.
- Proves deps.progressProvider is inert by supplying a throwing stub to
  all ten transition intents.

Verification through the remote runner only.

Refs #3118

* fix(#3118): distinguish an unreadable transcript from an empty one

antigravityWatermark's final read can throw on a transcript that
indisputably exists. It returned lines:0, which is the same value a
genuinely empty transcript produces, so the caller could not tell the
two apart.

antigravityTranscriptFallback derives its skip from that count. A mark
of {convId:'c1', lines:0} for a conversation that pre-dates the run
makes it skip nothing and return the last PLANNER_RESPONSE in a
transcript written before this run started — a previous review
presented as this one's, which is exactly what the function's own
'never stale' docstring promises cannot happen.

The unreadable case now sets unreadable:true and the fallback declines
for a same-conv-id unreadable mark. An absent or empty transcript is
untouched: those genuinely have zero prior lines.

* fix(#3118): escape the export line for the file it lands in, not the echo

Three lanes emit export PATH="<dir>:$PATH". repair escaped it with
escapePosixDoubleQuoted; persist and the win32 Git Bash lane escaped it
with escapeSingleQuotedShellLiteral instead.

The single-quoting is correct for the echo, so nothing runs when the
user pastes the command. But the bytes appended to ~/.bashrc are the
export line itself, and inside double quotes in an rc file a $(...) or
a backtick in the directory name is command substitution that runs on
every new shell. Those characters are legal in a path on both POSIX and
Windows, so the path was reachable.

projectPathExportLine is now the single source of that line and escapes
for its final rc-file context; each lane still applies its own transport
escaping on top. fish keeps the single-quote escaper — its value really
does stay single-quoted.

The cmd.exe lane interpolated into a cmd double-quoted string with no
cmd-level escaping, so a quote closed the region and &cmd& ran. A quote
is reserved on Windows and cannot appear in a real path, so there is no
correct command to suggest: the win32 lanes now fail closed for one.

Metacharacter-free paths render byte-identically on every lane.

* fix(#3118): drop a stray carriage return and a deps field nobody reads

locateCurrentPosition subtracted a fixed one byte to exclude the newline
before the next heading, which assumes LF. On a CRLF document the slice
kept an unpaired trailing carriage return. It now walks back over the
newline and over a preceding carriage return if there is one.

StateTransitionDeps also required a progressProvider that 33 sites
supplied and no site ever called. A required field nothing reads widens
the module's interface without changing its implementation, which is the
shape epic #3051 cites as its reason for refusing blanket injection.
Removed along with the ProgressRecord alias that existed only as its
return type; state-document.cts's unrelated interface of the same name
is untouched.

* fix(#3118): stop an empty span duplicating bytes, and name the empty results

Three findings from the isolated review pass.

locateCurrentPosition could return end < start when the section was
empty and the next heading followed with no blank line between. Every
mutator splices with slice(0,start) + body + slice(end), so an inverted
span duplicated the region between them — a blank line silently
inserted into STATE.md on every transition, two bytes on CRLF. The span
is now clamped, and an empty section is a zero-length span, which is
what it always meant.

The win32 fail-closed path left the installer printing 'Add it with one
of:' with nothing under it. An empty shellActions folded two different
facts together, so projectPathActionProjection now carries a frozen
PATH_ACTION_REASON and the installer branches on it. Two empty results
with different causes staying distinguishable is the subject of the
epic this belongs to.

fish_add_path parses a leading dash as an option, so a directory named
-v printed 'No paths to add' instead of being added. Verified against
fish 4.8.1: the end-of-options separator fixes it.

Replaces the console-prose test the second fix first arrived with — a
regex over captured stdout is what CONTRIBUTING prohibits, and the
typed reason is the surface it asks for instead.

* fix(#3118): escape TOML control characters, and stop a test name overstating

Five findings from the two review axes.

escapeTomlDoubleQuotedString escaped only backslash and quote. TOML
basic strings also require U+0000-U+0008, U+000A-U+001F and U+007F to be
escaped, so a value carrying a raw newline or NUL wrote a config.toml no
parser accepts — rejecting the whole file, not just that value. Four of
its call sites write real config. Tab stays raw; the grammar exempts it.

The byte-identity test claimed every lane was unchanged for an ordinary
path, which is false: fish now takes the end-of-options separator on
every path, not only hostile ones. Renamed, and the one intended delta
now has its own named test instead of hiding inside a claim that read
as broader than it was.

Also: exact-equality assertions in place of substring checks that could
pass on a subtly wrong escape, newline and null-byte cases for all five
quoting primitives, and a temp dir registered with t.after so it is
removed when an assertion fails.

* docs(#3118): add the changeset fragments

* fix(#3118): degrade instead of throwing on a null conversation cache

A cache file whose whole content is the literal null — what a truncated
or zeroed write leaves behind — made both antigravityWatermark and
antigravityTranscriptFallback throw. JSON.parse('null') succeeds, so the
try/catch wrapping the parse never fired, and resolveConvId then called
hasOwnProperty on null.

Both functions advertise the opposite; the existing test next to them is
named 'a missing cache or transcript degrades to empty, never throws'.
Parsing successfully is not the same fact as the payload being usable,
and a guard that only wraps the parse cannot tell them apart.

resolveConvId is now total for any non-object input, so one guard covers
both callers. Caught by the null case in this wave's own cache matrix.

* test(#3118): correct a stale fish expectation and a parity comparison

The pre-existing 'POSIX persist mode escapes single quotes' test pinned
fish_add_path without the end-of-options separator this wave adds, so it
asserted behavior that is no longer correct. A repo-wide scan found one
such hardcoded expectation; every other site derives its expectation
from the projection.

The new parity test compared the token from a POSIX path against the
win32 lane, which posix-normalizes its input first — two different
inputs, so the tokens differed for a reason that had nothing to do with
the parity it claims to check. It now derives the win32 expectation from
the same input the lane receives.

* docs(#3118): reword a comment the injection scanner reads as an instruction

The scanner pattern act\s+as\s+(?:a|an|the)\s+ carries no word
boundary, so 'the same fact as the payload' matched on the tail of
'fact'. Reworded per the documented remedy for this collision.

The missing boundary is a scanner defect rather than a prose problem —
any contributor writing 'fact as the' trips it — but the pattern is
gate plumbing, which the sibling epic owns, so it is surfaced rather
than changed here.

* chore(#3118): backfill changeset pr number to 3124

* chore(#3118): backfill changeset pr number to 3124

* fix(#2784): make the negation scan single-pass and index it correctly

Three defects in the negation suppression added by #3127, all in one
block, none of which had a test.

The pair scan was verbs.some(nouns.some(...)) with a slice and a split
per pair, so it grew cubically with clause length: 1.1ms before that PR
and 8462ms after, on 800 verb+noun pairs in one clause. api-coverage's
property test generates documents large enough to reach the runner's
600s file cap, which is why it hangs as 'fail 0, cancelled 1' rather
than failing an assertion. Every (verb, noun) window is a subset of the
single widest one, so one scan of that window answers the same question
in a linear pass. Verified equivalent against the old predicate over
20,000 generated clauses.

Both checks also subtracted clause.start from offsets that collectTerm-
Matches already returns clause-local. The first clause on a line has
start 0 so it worked there and nowhere else: later clauses went
negative, and slice reads a negative index from the end, so suppression
silently examined unrelated text.

The comment claimed 'without any API integration' was suppressed. It is
not — the qualifier sits outside the two-word lookback and the noun
precedes the verb. Widening the window would trade a false positive
that costs one declaration line for a false negative that slips a real
integration past a blocking gate, so the behavior stands and the
comment now says so. Pinned by a test.

The qualifier sets were also rebuilt for every line of every document.

behaviors. RED on next: the guard's entire scan is nested inside
`if (stateVersion && stateVersion === version)`, so any STATE.md milestone:
value that does not exactly equal the version argument skips the scan with
no warning — functionally an implicit --force on a one-way-door operation.

* fix(#2946): run milestone complete unstarted-phase guard independent of STATE

The entire ROADMAP phase-directory scan was nested inside
`if (stateVersion && stateVersion === version)`, so any STATE.md milestone:
value that did not exactly string-equal the version argument — a desynced
value, or no milestone: field at all — skipped the scan with no warning,
functionally an implicit --force. The operation the guard fronts is a one-way
door: ROADMAP.md and REQUIREMENTS.md are archived and phase directories are
MOVED into .planning/milestones/<version>-phases/.

The scan was already driven by the version argument through
getMilestonePhaseFilter / extractCurrentMilestone; the STATE match was a
redundant second gate that shadowed and broke it. Decouple: the scan now runs
whenever --force is absent, and a present-but-mismatched STATE milestone:
field emits a WARNING naming both values so the suspicious condition is
visible rather than silent. A fresh project with no Phase headings in the
scoped slice still yields an empty scan (no false positives) — the intent the
STATE-match short-circuit was reaching for, now achieved by the scan itself.

* docs(#2946): document milestone complete --force, --dry-run, and the unstarted-phase guard

The CLI-TOOLS reference signature omitted --force and --dry-run entirely,
and neither the unstarted-phase guard nor its override was documented
anywhere user-facing. Add a flags table and a factual guard description
to the Reference page (CLI-TOOLS.md), and a practical guard note to the
/gsd-complete-milestone How-to (COMMANDS.md) covering what to do when
the guard fires and the new STATE-mismatch WARNING (#2946).

American English per CONTRIBUTING.md language policy.

* fix(#2946): emit STATE-mismatch WARNING as JSON in --json-errors mode

Follow-up to the guard decoupling: a structured caller using --json-errors
parses stderr line-by-line as JSON, so the plain-text WARNING would break
such a parser. Honor getJsonErrorMode() and emit a structured JSON object
({ ok, level, message }) in that mode, plain text otherwise — mirroring
io.cts error()'s JSON shape. Addresses the isolated-review observation
(~45% but credible, since --json-errors is a documented CLI flag).

* fix(#2946): address review — drop JSON-mode WARNING scope creep, tighten test assertions

Standards + spec review findings (code-review two-axis + isolated adversarial):

1. The --json-errors JSON WARNING branch (commit dee719404) was scope creep
   the issue never asked for, AND emitted ok:true for a suspicious-condition
   warning (a category error — a stderr JSON parser keying on ok would treat
   the suspicious state as success), AND its comment falsely claimed to mirror
   io.cts error()'s {ok:false,reason,message} shape. Dropped: the WARNING is
   now plain-text stderr only, matching the existing [gsd-tools] WARNING
   convention (state.cts). The issue asked for 'at minimum warn', not a
   structured JSON surface.

2. The WARNING test asserted on /WARNING/ regex (raw-text matching on stderr
   prose). Tightened to assert on the stable operator-facing tokens — the
   WARNING: marker and both version literals the operator must see — not the
   surrounding formatter prose. Added a paired negative test confirming no
   WARNING is emitted for an absent milestone: field (a missing declaration
   is a normal fresh-project state, not suspicious drift).

* fix(#2946): sanitize STATE milestone value before stderr WARNING interpolation

Security review (minor): stateVersion is read from a user-controlled file
(STATE.md) and is not validated like the CLI version arg. Sanitize before
interpolating into the WARNING — strip ANSI/control chars
(/[\x00-\x1f\x7f]/g -> '?') and truncate to 80 chars — so a corrupted or
hostile STATE.md cannot echo terminal escapes or secret-looking strings
verbatim into a CI log or terminal aggregator (CONTRIBUTING.md security:
secret-looking values in stderr). version is already constrained to
[A-Za-z0-9._-] by ARCHIVE_VERSION_LABEL_RE upstream, so it needs no
sanitization.

* test(#2946): correct stale fixtures that relied on the guard being silently disabled

Four pre-existing tests broke under the #2946 fix because their fixtures
only passed thanks to the bug — the unstarted-phase guard was skipping on
STATE mismatch, so fixtures with missing or non-matching phase directories
slipped through. The tests exercise version-forwarding / version-scoping,
not the guard, so give them legitimate directories:

- milestone.test.cjs #3043: dirs were '103.old'/'104.old'/'108.new' (dot),
  which phaseTokenMatches rejects — renamed to hyphen form. The v3.6 stats
  scoping still yields 1 phase (getMilestonePhaseFilter scopes correctly);
  the guard now sees all three phases as having directories.
- milestone-archive.test.cjs 'returns version in response data': ROADMAP
  listed Phase 1 but no directory was created. Added 01-foundation so the
  scan is satisfied.

Per CONTRIBUTING.md, test-fixture corrections land as their own test:
commit, not bundled into fix: (release hotfix cherry-pick routes by prefix).

* fix(#2788): recover Gaps Found rows; mark-complete no longer false-succeeds on a rejected row

Two coupled defects in the requirement traceability state machine:

Defect 1 (terminal state): requirements revert-phase (the gaps_found response)
left a row at 'Gaps Found' with no inverse — neither mark-complete's /^pending$/i
guard nor the phase-complete reconcile's /^(?:pending|in progress)$/i accepted it,
so a single failed verification stranded every requirement permanently and blocked
the milestone. Widen both guards to accept 'gaps found' so a genuinely-satisfied
stranded row reaches Complete again.

Defect 2 (false success): mark-complete ORed checkboxHit || tableHit for 'updated',
so on a Gaps Found row it flipped the checkbox but could not move the row, yet
reported updated:true. When a traceability table has a row for an ID, gate 'updated'
on the row moving (tableHit) — a checkbox-only flip on a table-bearing file no
longer lies. The #2140 table_unmatched path (no row for the ID) is preserved.

9a76ca6783 fix(#1882): distinguish unterminated frontmatter from absent frontmatter (#2712)
* fix(#1882): distinguish unterminated frontmatter from absent frontmatter

extractFrontmatter returned {} both for a document with no frontmatter and for
one whose fence was opened and never closed, so a file truncated mid-write was
byte-identical to a legitimate no-metadata file. Verified live through
`gsd-tools frontmatter get`: both printed {} with exit 0 and nothing on stderr.

Per ADR-1411's "corrupt is not absent" amendment the {} return is preserved
exactly -- no caller may break -- and the cause is surfaced out-of-band as a
deduplicated, unconditional stderr diagnostic. That mechanism lands as a shared
leaf module rather than a per-site copy because three sibling findings in the
same epic need it identically; four hand-rolled copies of one behaviour is the
generative-fix-divergence defect class.

The discriminator is deliberately not "opened but never closed". A Markdown
document whose first line is a thematic break takes that exact branch, so
flagging on the missing fence alone reports corruption on good Markdown -- the
failure mode this class of check has shipped with before. The unterminated
region is instead run through extractFrontmatter's own parser (extracted as
parseYamlRegion so the probe and the real parse can never diverge) and reported
only when it yields at least one key.

Also folds an inline defect found while working: src/config-loader.cts carried
two NUL bytes in the JSDoc added by this epic's Phase 1 (3eb1cede2), making it
the only non-text file under src. file(1) reported it as data and text tools
silently skipped it, defeating the audit rule that says to search the authored
source; tsc passed because the bytes sat inside a comment, so no gate caught it.
It is live on next.

* test(#1882): pin unterminated-frontmatter detection and its negative space

Covers the discriminator on both sides. The positive rows are the issue's own
repro (LF and CRLF) plus the key-count boundary 0/1/2 around the ">= 1 parsed
key" threshold. The negative rows are the documents that reach the same branch
and must stay silent -- above all a Markdown thematic break at byte 0, which is
how this class of check has previously shipped a false positive on valid
Markdown.

Deduplication is tested on both halves of the composite key: a repeat of the
same (path, cause) is suppressed, a genuine second failure in a different file
is not, and a Windows and POSIX spelling of one path resolve to a single key.
The reset seam is asserted to actually clear -- #2674 is the precedent where a
reset that silently failed to clear made every later dedup assertion a vacuous
pass, and the cases only passed because each happened to pick an unused key, so
every case here uses a path unique to itself.

Assertions are on typed surfaces throughout -- the frozen reason enum and the
dedup-set size -- never on diagnostic prose. The one CLI-level case asserts a
differential between two runs (whether stderr is empty) rather than matching a
message, and is the wired user-reachable surface for this fix. Stream failure is
injected by overriding process.stderr.write and restoring it, never chmod 0o000,
which root bypasses.

Two properties guard the ~50 call sites of the changed function: the new
optional path argument is inert with respect to the parsed value, and LF/CRLF
spellings of a document still parse identically.

* fix(#1882): raise the truncation threshold and repair the dedup key

Isolated adversarial review found the one-key discriminator false-positives on
ordinary Markdown: a thematic break above a single labelled line -- `Note:`,
`Author:`, `TODO:`, `See:` -- parses as exactly one key and was reported as
corruption, which is the precise failure the design claimed to prevent and the
changeset promised was fixed. The threshold is now two keys. A file truncated
after exactly one key becomes a false negative; that is the same
precision-over-recall direction already taken at zero keys, and every GSD
artefact this guards carries two or more frontmatter keys.

Three dedup-key defects, each of which could silently swallow a real diagnostic:

- Backslash normalization is removed. A backslash is a legal filename character
  on Linux and macOS, so folding it to a forward slash made two genuinely
  different files share one key. Two spellings of one Windows path may now
  report twice; two distinct files can never silence each other. Lost signal is
  the worse failure.
- The key namespaces are tagged so a file literally named like the unnamed
  digest fallback can no longer collide with a path-less caller whose content
  hashes to that digest -- computable for any predictable content, no brute
  force needed.
- The source identity is computed once rather than hashed twice per emission.

Corrects the previous commit. The two NUL bytes in src/config-loader.cts were
NOT in a JSDoc comment as that message claimed; they were deliberate separators
in the live dedup key, and stripping them degraded it to bare concatenation.
They are restored as escape sequences -- byte-identical runtime string, and the
file is text again so grep can see it. The diagnostic script that misled me
indexed a character-offset string with a byte offset.

Also threads sourcePath through the STATE.md and PLAN.md readers so the two
artefacts epic #1879 is actually about name their file rather than reporting
under a content digest.

* test(#1882): correct fixtures and assertions left behind by the review fixes

The previous commit changed two behaviours deliberately and the suite still
encoded the old ones, so gsd-test came back red with six failures across both
lanes -- all of them mine.

Fixtures carrying a single frontmatter key no longer clear the two-key
truncation threshold, so the CLI differential and the two path-less dedup cases
were asserting a diagnostic that is now correctly withheld. They now carry two
keys, which is what a real interrupted write of a GSD artefact looks like.

The Windows/POSIX case asserted that two spellings of one path collapse to a
single key -- the exact folding that was removed because it also collapsed
genuinely distinct POSIX files whose names contain a backslash. Inverted to
assert they now report separately, with the reasoning recorded inline so the
trade is not silently reversed later: mild duplicate noise on one Windows path
is acceptable, a swallowed diagnostic is not.

Refs #1879

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#1882): name the file at every read site, and report each file once

The diagnostic reached only the four frontmatter CLI verbs, so ~47 of 53 call
sites reported a truncated file under an anonymous content digest instead of
naming it. Since naming the file is the whole point -- it is what an operator
can act on -- that was a gap in the deliverable, not a scoping choice. 43 of 53
sites now pass the resolved path.

Closing it surfaced a defect the original design missed. A single truncated
STATE.md is parsed twice in a normal run: once by the read wrapper, which holds
the path, and again by a pure core downstream, which is handed only the string
and cannot know it. Those two parses keyed separately, so one file produced two
diagnostics -- and wiring more sites made the collision more likely, not less.
Every emission now registers both identities the input could be known by and
checks both before writing, so whichever caller arrives first speaks and the
other is suppressed. Distinct files with distinct content still report
separately, which is the property ADR-1411 actually requires; two files whose
truncated content is byte-identical collapse to one report, which stays the
documented limit.

Ten call sites deliberately keep no path. Two are frontmatter's own round-trip
checks during set and merge, where passing a path would report on every write.
The other eight are the state-transition pure cores, which ADR-1769 defines as
(content, intent, deps) -> newContent with injected I/O; threading a path
through them would contradict that recorded decision, so it is surfaced rather
than taken unilaterally. With the widened key they no longer double-report, and
in the normal flow the named parse runs first, so the file is still named.

Refs #1879

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* fix(#1882): inject the STATE.md path into the transition cores

The six state-transition cores parsed STATE.md frontmatter without knowing
which file it came from, so a truncated STATE.md reached the operator as an
anonymous content digest on exactly the artefact epic #1879 is named for.

ADR-1769 section 3 shapes these as (content, intent, deps) -> newContent with
injected deps, and deps is the seam for precisely this: something the core
cannot derive without doing I/O. It already carries roadmapProvider and a
phase-inventory provider on that basis, each documented as injected rather than
imported so the core stays pure and testable without disk access. A resolved
path is data, not I/O, so an optional sourcePath member extends the established
pattern rather than contradicting it, and every existing stub keeps compiling
because the member is optional.

updateCore and reconcileCurrentPosition take no deps and are left alone. With
the widened dedup key they cannot double-report, and in the normal flow the read
wrapper has already named the file by the time they run.

Also regenerates gsd-core/bin/lib/state-transition.cjs. That artifact is tracked
rather than gitignored, unlike most of its siblings, so leaving it stale would
have shipped a runtime without this change to anyone reading the repo without
building. tsc had skipped the re-emit because its incremental build info still
recorded an emit that had since been reverted, so the stale output survived a
clean build; clearing tsconfig.build.tsbuildinfo forced it. The
compiled-artifact-sync gate is what surfaced the drift and now reports all nine
tracked artifacts matching their source.

* fix(#1882): stop the widened dedup key from hiding a second file

The previous commit widened the dedup guard so one file parsed twice -- once by
a read wrapper holding the path, once by a pure core holding only the string --
reported once instead of twice. It did that by checking BOTH keys before
emitting, which silently traded one defect for a worse one: two DIFFERENT files
whose truncated content happened to be byte-identical now collided on the shared
content digest, and the second file's diagnostic was swallowed. That is the
over-coarse keying ADR-1411 explicitly forbids, reintroduced while fixing
something else.

The guard now checks only the key matching what the caller actually knows -- a
named read checks its path key, a path-less read checks its digest key -- while
still recording every key the input could later be identified by. The redundant
path-less re-parse of an already-named file stays silent, and two distinct files
always both report.

Verified across all six orderings: same file named-then-anonymous reports once;
two different files with identical content report twice; two different files
with different content report twice; the same path twice reports once; two
path-less parses of identical content report once; two path-less parses of
different content report twice.

The suite caught this -- twenty failures, all in the unusable-input tests that
reuse one truncated fixture across different paths. The local probe written
alongside the broken change did not, because it compared two files with
different content and could therefore only confirm the expected behaviour.

Refs #1879

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test(#1882): count diagnostics emitted, not identities interned

The suite measured the size of the dedup set as a stand-in for "how many
diagnostics were emitted". That held only while one emission recorded exactly
one key. Once an emission began recording every identity the input could later
be matched by -- a path key and a content key for the same file -- the set grew
by two per write and twenty assertions read 2 where they expected 1.

The production behaviour was correct throughout; the proxy was not. Set size
counts identities, which is an implementation detail of the guard. The
behavioural claim these tests exist to make is how many diagnostics an operator
actually saw, so the module now exposes that directly as an emission counter and
the suite asserts on it. The set-size accessor stays for assertions genuinely
about key shape.

The local probe written alongside the change did not catch this because it
counted process.stderr.write calls -- the right thing -- while the suite counted
set growth. Verification now asserts both and requires them to agree, so a
future divergence between the counter and real writes fails immediately rather
than being discovered a bench run later.

Refs #1879

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

* test(#1882): retire two assertions that outlived the behaviour they described

Both tests encoded assumptions the dedup fix invalidated, and both were caught
by the suite rather than by the probe written alongside the change.

The forged-path case asserted that a file named like the anonymous digest
fallback must not suppress a later path-less report. That premise is gone: an
emission now records every identity its input could be matched by, so ANY named
report of some content silences the anonymous re-parse of that same content --
which is the same-file guard working as intended, and has nothing to do with the
crafted name. The property still worth defending is that a crafted filename can
never silence a real file reported under its own path, so that is what the test
now asserts, with the deliberate suppression documented beside it.

The reset-seam case ended by reading the size of the dedup set and expecting 1.
Set size counts interned identities, not diagnostics written, and one emission
now interns two. It asserts the emission counter for the event and keeps a
weaker set-size check for the interning.

* fix(#1882): close the review findings on the discriminator, dry-run and counter

Three orthogonal review passes ran against the final diff. Their findings:

A labelled preamble under a leading rule was still misreported. Raising the key
threshold to two only moved the boundary, because two colon-labelled lines are
as common in ordinary prose as one -- a document opening with a rule over an
Author and a Reviewed-by line, then prose, was called corrupt. Key count alone
cannot separate the two. What does is what follows: a write interrupted part way
through a frontmatter block ends mid-block, so every line of the region is still
frontmatter-shaped, whereas a document merely opening with a rule goes on to
prose. Both conditions are now required, and each closes a false-positive class
the other leaves open. Nested list values and indented continuations stay
frontmatter-shaped, so legitimate truncations are unaffected.

`state rebuild --dry-run` reported a truncated STATE.md anonymously. The write
path is named only because readModifyWriteStateMd parses with the path first;
the dry-run branch reads the file directly and never did. Dry-run is the
read-only mode an operator reaches for first when they suspect corruption, so it
is the one that most needed to name the file. reconcileCurrentPosition takes the
path as an optional argument now and rebuildCore passes it down. That function
was previously left alone on the grounds that a read wrapper always names the
file first -- this is the flow that disproves it.

The emission counter counted write attempts rather than writes, so on a broken
stderr it claimed a diagnostic had reached the operator when nothing had. It is
incremented only after a write that completed, and the broken-stderr test now
asserts the count as well as the return value.

Two documentation defects. The module described a guarantee it does not keep:
one file yields one diagnostic only when the named read comes first. The reverse
ordering emits twice, and that is deliberate -- a path-less caller cannot
identify its file, so suppressing the later named report would also suppress a
genuine second failure in a different file whenever two files share identical
truncated bytes, which ADR-1411 ranks the worse failure. The comment now states
the asymmetric guarantee and a test pins it. Separately, the CONTEXT.md glossary
entry still described backslash normalization that a later commit removed, and
asserted the opposite of what the tests pin; no lint checks prose against code,
so nothing caught it.

Also converts three body-level try/finally blocks to t.after(), per
CONTRIBUTING.md's rule that try/finally belongs only in helpers with no test
context -- the file's own emissionsDuring helper already did this correctly.

* docs(#1882): tell the operator what the truncated-frontmatter warning means

A user who has just seen the new warning is acting, not studying, so this lands
in the How-To quadrant beside the other "if you see X" branches in
debug-a-failed-execution, not in reference or explanation. It gives them what
the warning means for this run, three steps to restore the file, and the fact
that the warning changes no return value or exit code.

It also states the case that matters more than the warning itself: silence does
not prove the file is intact. GSD says nothing when the partial block carries
fewer than two fields or reads as prose, because a Markdown document opening
with a horizontal rule is indistinguishable from one of those. A reader chasing
missing metadata needs to know not to treat quiet as clean. Why that threshold
exists is explanation and deliberately stays out of a how-to.

* chore(#1882): backfill changeset pr number to 2712

* test(#1882): constrain each branch of the frontmatter-shape check

CI's mutation gate came in at 61.56 against a threshold of 62, and the surviving
mutants were concentrated in isFrontmatterShaped -- the function added last, in
response to review, and the only one never given tests of its own. It was
exercised solely through extractFrontmatter, which covers the composite decision
but leaves each branch of the predicate unconstrained: drop the blank-line
filter, or any one of the three shape alternatives, and every existing assertion
still passed.

Four cases now pin the halves independently. A blank line inside an interrupted
block must not disqualify it, which constrains the filter and its comparison. An
unindented list item and an indented folded-scalar continuation each exercise one
shape alternative that no other case reaches on its own -- the folded line is
neither a key nor a list item, so it is the only input that distinguishes the
indented branch. And two keys followed by prose must stay silent, which is the
negative half: it fails if the predicate is ever mutated to accept everything,
and it is the case that proves key count alone was never sufficient.

* test(#1882): register the unusable-input suite with the frontmatter mutation shard

The mutation gate reported an identical 61.56 across two runs whose only
difference was four added tests. That is the tell: the tests were never
executed. The frontmatter shard runs a fixed file list in stryker.config.mjs and
scripts/mutation-matrix.cjs, and tests/unusable-input.test.cjs was in neither, so
the entire suite covering the new unterminated-fence branch was invisible to the
gate while passing perfectly well in the normal run.

So the score was not measuring weak tests, it was measuring absent ones: #1882
added mutants to frontmatter.cjs and no test in the shard covered them. Both
lists gain the file; the config already notes they must stay in sync.

This is a registration ripple a new test file carries when it covers a
mutation-tracked module, alongside the .gitignore, eslint, inventory, glossary
and size-baseline ripples a new module carries. Nothing warned about it, which
is why two runs were spent before the identical score gave it away.

c1885df9e5 chore(#2143): prohibition-with-teeth + migrate remaining ad-hoc table sites — Phase 4 (final) (#2253)
* chore(#2143): prohibition-with-teeth + migrate remaining table sites — Phase 4

Phase 4 of epic #2143 (ADR-2143 §7). Completes the markdown table/mutation
consolidation by (a) giving the ad-hoc-parsing prohibition teeth and (b)
migrating the last ad-hoc table sites onto the shared seam.

- src/markdown-table.cts: new formatting-preserving `updateTableCell` primitive
  (self-contained, ragged-row-tolerant header/delimiter/cell-range scan; splices
  only the target cell's raw span, preserving all other bytes incl. padding/CRLF;
  no-op-preserves-padding when a transformer returns the current value). Exports
  splitTableRow/isDelimiterRow/findTableStartOffset for tolerant reuse.
- eslint-rules/no-adhoc-markdown-parsing.cjs: TABLE-REGEX detector extended to
  `new RegExp(<literal|static-template>)`; new `.replace()`-mutation detector for
  roadmap/state/content receivers with a table/section-shaped pattern.
- scripts/lint-table-schema-drift.cjs (wired into lint:ci): fails if a TABLE_SCHEMA
  header drifts from its authored table; tests import its logic (single source).
- Migrated onto the seam (behaviour-preserving vs pre-Phase-4 HEAD, verified
  byte-diff old-vs-new): roadmap.cts cmdRoadmapUpdatePlanProgress, phase.cts
  cmdPhaseComplete + traceability, milestone.cts cmdRequirementsMarkComplete,
  uat.cts read path, state.cts metrics/decisions/By-Phase.
- Incidental correctness gains from the migration: a decoy table can no longer
  swallow a phase-progress update (## Progress scoping); a ragged neighbouring
  row no longer silently aborts an edit; completing integer phase N no longer
  touches a decimal sub-phase N.x row; record-metric no longer drops trailing
  section content or duplicates the ## Performance Metrics section.
- Kept justified allow-adhoc-markdown markers only where genuinely not a table
  (security.cts <|role|> token) or a loose non-GFM section (uat human-verify).

Two orthogonal isolated reviews (correctness/adversarial + security) passed;
correctness found 4 behaviour regressions in the first migration pass, all fixed
and re-verified byte-identical-or-better vs OLD.

Surfaced for maintainer (pre-existing, ambiguous domain logic, NOT changed here):
templates/state.md places a By-Phase table under ## Performance Metrics while
cmdStateRecordMetric assumes a Plan|Duration|Tasks|Files table.

* fix(#2143): match traceability row by first-cell value, not Requirement header

Phase 4's migration matched the REQUIREMENTS.md traceability row by a column
literally named `Requirement` (`row['Requirement']`), but real tables head that
column `REQ-ID`. The by-name lookup found nothing, so `phase complete` and
`requirements mark-complete` left the Status cell `Pending` (regressed #2769 /
#2203, caught by gsd-test — 8 failures, both node 22/24).

- src/phase.cts, src/milestone.cts: match the row by its FIRST cell's value
  (the requirement-ID column) regardless of that column's HEADER name, via
  `Object.values(row)[0]` (updateTableCell builds the record in header order).
  This mirrors OLD's first-cell `\|\s*<id>\s*\|` anchor, restoring header-name
  independence while keeping the seam.
- src/milestone.cts hasTable: broadened from `Requirement`-only to also
  recognize `Requirement ID` / `REQ-ID` / `REQ ID` headers, kept in sync with
  the now-positional rowMatch/hasRow so a REQ-ID-headed table participates in
  the ADR-2143 §6 write-set and the #2140 table_unmatched drift check (it was
  silently omitted before — a checkbox-only partial reconcile against a REQ-ID
  table could report as fully reconciled). The `Requirement`-headed path is
  byte-identical to OLD.

* test(#2143): replace stale structural milestone guards with behavioural suite

The `milestone.cjs regex global state fix` block was a source-structure guard
(allow-test-rule: structural-regression-guard) — it readFileSync'd the compiled
milestone.cjs and asserted removed regex idioms (`tablePattern.test`,
`afterTable !== reqContent`, `doneTable = new RegExp(...)`). Phase 4's migration
deleted those regexes (table update is now updateTableCell), making the
assertions obsolete. Per the Test Cleanup rule, replace them in-PR with a
behavioural suite driving the compiled CLI:

- multi-ID mark-complete flips all IDs (guards the lastIndex/global-state class),
- Pending->Complete flip under both `REQ-ID` and `Requirement` headers (#2769),
- idempotent already_complete detection with no corruption,
- REQ-ID-headed table participates in write_set (traceability entry, applied),
- REQ-ID-headed table trips #2140 table_unmatched drift on a missing row.

Pruned the now-nonexistent structural-regression-guard entry from the
lint-allow-test-rule-refs allowlist (the source-text-is-the-product entry for
the same file remains valid).

* chore(changeset): backfill PR number 2253

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

* fix(#2143): record-metric targets its own metrics table, not By-Phase velocity

`state record-metric` appended its per-plan row (`| Phase 1 P1 | 5min | 3 tasks |
4 files |`) into the FIRST table under `## Performance Metrics` — which on a real
template-derived STATE.md is the By-Phase velocity table `| Phase | Plans | Total
| Avg/Plan |`, polluting it on EVERY plan completion (execute-plan.md:414 is a
per-plan call). The command's own metrics table is `| Plan | Duration | Tasks |
Files |`, which the template does not ship, so the row never reached it; the
scaffold branch also emitted a wrong `| Phase | Plan | Duration | Notes |` header
matching neither the row nor the canonical table.

Pre-existing (predates Phase 4); surfaced while migrating this site and fixed here
per no-defer, on the user's explicit go-ahead.

- src/state.cts cmdStateRecordMetric: locate the metrics table by its own header
  shape (`Plan|Duration|Tasks|Files`, via splitTableRow/isDelimiterRow) rather
  than "first table in the section". When the section exists but has no metrics
  table (only the By-Phase table), self-heal by appending a fresh **Per-Plan
  Metrics:** table to the END of the section body — By-Phase table, Recent Trend
  and footer preserved verbatim, no duplicate `## Performance Metrics` heading,
  created stays false. Absent-section scaffold header corrected to the canonical
  `| Plan | Duration | Tasks | Files |`. Ragged-tolerance + None-yet preserved.
- Not touching templates/state.md (golden-install-parity hashed) — record-metric
  self-creates the table on first use instead.

Failing-first regression test (tests/state.test.cjs) demonstrates the By-Phase
pollution on the pre-fix build, then green after. Verified: no pollution, self-
heal idempotency, both-tables isolation, content/heading preservation, flags,
None-yet, corrected scaffold header (23-check adversarial harness + all existing
record-metric scenarios).

* feat(#2143): deleteSection seam primitive (level-bounded whole-section removal)

ADR-2143 §4 shipped withSection/collectSection (replace a section BODY) but no
way to DELETE a section (heading + body). Phase 4 suppressed the phase-remove
section delete instead of building it. deleteSection(content, predicate, opts)
locates the section via the collectSection machinery and splices out from the
heading's start offset to the next same-or-higher-level heading — so a level-3
`### Phase N` delete stops at a following level-2 `## Progress`, never past it.

* fix(#2143): phase remove no longer deletes ## Progress on last-phase removal

updateRoadmapAfterPhaseRemoval deleted a `### Phase N` detail section with a
greedy raw regex whose lazy scan, on the LAST phase, ran to EOF and destroyed
the following `## Progress` heading and its entire tracking table — silent data
loss, uncovered by tests (removal tests only exercised a middle phase). Migrated
onto the new deleteSection seam (level-bounded, stops at `## Progress`); dropped
the allow-adhoc-markdown SECTION-DELETION suppression. Failing-first regression
(tests/phase.test.cjs) removes the LAST phase and asserts the ## Progress heading
+ table survive; middle-phase removal is byte-identical.

* feat(#2143): deleteTableRow seam primitive (row removal, ragged-tolerant)

Sibling of updateTableCell: locates the first GFM table, matches a DATA row by
predicate (ragged-tolerant record build, header order), and splices out that
row's whole line preserving every other byte. Returns {ok:false,reason} on no
table / no match. Enables migrating the phase-remove Progress-table row delete
off its ad-hoc regex (ADR-2143 §7 — the "future row-delete seam" Phase 4 punted).

* fix(#2143): phase remove deletes the Progress row via deleteTableRow

The Progress-table row delete used a whole-document regex with two defects:
(a) `\.?\s` required whitespace after the phase number, so a COMPACT row
`|2|Beta|` was never deleted (stale row left behind); (b) unscoped — it could
strike a row in a different table (e.g. an earlier `| Phase | Requirements |`
table). Migrated onto deleteTableRow, scoped to the `## Progress` section
(mirrors deriveProgressFromRoadmap), matching the row by first-cell phase number
(integer zero-pad-insensitive; decimal exact; removing `2` never touches `2.5`).
Both allow-adhoc-markdown suppressions removed. New behavioural tests: compact
unpadded row deleted; padded byte-parity on the surviving rows (their ordinal
correctly renumbers via the pre-existing renumber block).

* fix(#2143): deleteTableRow leaves no dangling newline on last EOL-less row

Deleting the final row of a table with no trailing EOL sliced from the row's
start to end-of-string, stranding the newline that terminated the previous line.
Back rowStart over the preceding \r?\n in that branch so the table ends cleanly.
(Caught by the primitive's own unit test on gsd-test; local scenario checks
missed the no-trailing-EOL edge.)

* fix(#2143): migrate read-only section-collects onto collectSection

Six hand-rolled `## Section` read-extract regexes replaced by the collectSection
seam (behaviour-preserving; extracted bodies feed the same downstream parsers):
state.cts matchSessionSection (## Session / ## Session Continuity) + ## Blockers,
smart-entry.cts ## Blockers, audit.cts ## Current Focus + ## Open Questions.
Removes 6 allow-adhoc-markdown "pending #1372" suppressions. Incidental fix: the
old Session regex `## Session[ \t]*\n` silently failed on a CRLF `## Session\r\n`
heading (Windows STATE.md), nulling all session fields; collectSection is
CRLF-safe, so session state now resolves on Windows.

* fix(#2143): fence-safe state-transition section writes + dedup stripFrontmatter

- milestoneCompleteCore's `## Current Position` and `## Operator Next Steps`
  section resets used fence-blind raw regexes that a fenced `##` inside the body
  could truncate/mis-target (#2130/#2067/#2080 class). Migrated onto a
  fence-aware tokenizeHeadings-based helper (resetSectionVerbatim) that is
  byte-identical to the old output on the canonical path (9/9 fixtures) and
  correctly ignores a fenced fake heading (proven robustness gain).
- mutateCurrentPositionFirstTime: hand-rolled locate+splice → collectSection +
  replaceSection (byte-parity).
- stripFrontmatter was inlined byte-identically in state.cts AND
  state-transition.cts; hoisted the single canonical copy into frontmatter.cts
  (both call sites now import it) + unit tests — eliminates the divergence risk
  per CLAUDE.md "Generative Fix Divergence". Removes 3 allow-adhoc-markdown /
  #1372 markers.

* fix(#2143): name-address By-Phase sum + uat parse, eslint recall hole, catches

- state.cts By-Phase "Total plans completed" sum: positional 2nd-cell regex →
  name-addressed splitTableRow read (correct on a reordered header, where the
  old code silently summed the wrong column). Marker removed.
- uat.cts parseVerificationItems: loose pipe regex → splitTableRow within the
  existing table/numbered/bullet union scan (item list byte-identical; does NOT
  reintroduce the reverted strict-parseMarkdownTable item-drop). Marker removed.
- eslint no-adhoc-markdown-parsing: close the `new RegExp(identifier)` recall
  hole — resolve a const-declared table-shaped regex identifier (mirrors the
  .replace() detector) + RuleTester cases; param/call args stay out (boundary).
- commands.cts: delete a lying comment that claimed the scaffold date "stays on
  raw UTC / deferred" — #2136 already moved it to realClock.localToday().
- Empty catches (classified, not blind-swept): removed 4 dead try/catch;
  fixed 3 error-hiding (phase-insert decimal-dir I/O collision now fails loud;
  phase-remove rename partial-failure surfaced; milestone-archive true count via
  finally); left best-effort swallows with justification comments.

* fix(#2143): extractFencedBlock seam + migrate api-coverage named fence

parseCoverageMatrix extracted its ```coverage fenced block with an ad-hoc regex
(the last real allow-adhoc-markdown suppression). Added extractFencedBlock to the
markdown-sectionizer seam (reuses stripFencedCode's CommonMark fence engine —
info-string match, ~~~/backtick, nesting, indent) and migrated onto it; byte-
parity on the parsed CoverageMatrix across 8 fixtures. Only security.cts:367
(a genuine `<|role|>` protocol-token false-positive, not a GFM table) remains
marked in src/ — the "prohibition with teeth" goal (nothing grandfathered but a
true FP) is met.

* fix(#2143): By-Phase row insert is name-addressed (insertTableRow seam)

updatePerformanceMetricsSection's INSERT-new-row branch located the By-Phase
table with a canonical-column-order-only regex + a hardcoded positional row
literal, so on a reordered header it silently inserted nothing — inconsistent
with the now name-addressed UPDATE and SUM halves of the same function. Added
insertTableRow (markdown-table seam sibling of updateTableCell/deleteTableRow:
name-addressed, header-order-agnostic, EOL-preserving) and migrated the branch
onto it, mapping By-Phase values by column NAME. Canonical-order output is
byte-identical; a reordered header now inserts a correctly-mapped row; a
pre-existing CRLF mixed-EOL splice glitch is incidentally fixed. Retired the
now-dead byPhaseTablePattern const.

* fix(#2143): phase-list checkbox flip via updateBullet seam

Added updateBullet (markdown-sectionizer): a fence-aware, offset-tracked
single-bullet write primitive (GFM 1–4-space marker tolerance) — the write
counterpart to read-only iterateBullets. Migrated mutateMilestonePhase's
phase-list checkbox flip (`- [ ] Phase N …` → `- [x] … (completed <date>)`)
off its whole-slice regex onto it, same milestone-slice scope + clock seam.
Byte-identical across simple / idempotent / metachar-title / double-space /
CRLF scenarios.

* fix(#2143): scope the Progress-ordinal renumber to ## Progress via seam

phase remove's integer-renumber decremented Progress-table phase ordinals with a
whole-document `content.replace(/(\|\s*)(\d+)(\.\s)/g, …)` — unscoped, so it also
rewrote any `| N. …` cell in an unrelated/decoy table (same class as the batch-2
row-delete scoping bug). Migrated onto updateTableCell, scoped to the ## Progress
section, decrementing each affected row's leading phase ordinal by column name.
Byte-identical on canonical Progress tables + multi-row + decimal-sibling cases;
a decoy `| 3. … |` row before ## Progress is now correctly left untouched. The
sibling heading / checkbox-bullet / PLAN.md-filename / Depends-on-prose renumbers
are not GFM-table mutations (outside ADR-2143's table/section mandate) — left as-is.

* fix(#2143): review fixes — scope traceability write, restore Current Position H3-stop

Adversarial review of the remediation (BLOCK verdict) — all 9 findings fixed:
- F1 (BLOCKER): requirements mark-complete / phase complete flipped the checkbox
  but NOT the traceability row on the shipped template, because updateTableCell
  bound to the FIRST table (## Out of Scope, no Status column) instead of the
  ## Traceability table — the #2140 silent-divergence class, re-introduced by the
  seam migration and missed by tests (fixtures had Traceability first). Scoped
  the write + hasRow probe to the ## Traceability section slice (updateTraceability
  Cell helper) in milestone.cts + phase.cts. Failing-first tests on the
  Out-of-Scope-before-Traceability layout; the #2769 first-cell match preserved.
- F2 (MAJOR): mutateCurrentPositionFirstTime restored to locateCurrentPosition
  (STOP_H2_PLUS) — collectSection's default H2-stop swallowed a level-3 subsection
  and the field regexes clobbered it (#2130 class).
- F3/F8: Progress-ordinal renumber re-escapes via escapeCell + keys padding
  recovery by row index (was de-escaping `\|` and losing padding on dup values).
- F4: insertTableRow escapes cell values internally.
- F5: updateBullet accepts a tab after the marker (`[ \t]{1,4}`).
- F7: resetSectionVerbatim consumes CRLF blank lines (byte-parity on CRLF).
- F6/F9: corrected two misleading comments.

The G10 test asserted `elapsedMs < 1000` for a 200k-char payload — a wall-clock
assertion (CLAUDE.md: never assert on wall-clock time) that flaked on a loaded
node24 bench at ~1.1s. It was redundant: runHook's spawnSync `timeout: 10000`
already SIGKILLs a catastrophic-backtracking hook, so the exit-0 assertion is the
real ReDoS guard. Removed the timing assertion; kept exit-0 + documented the
subprocess-timeout mechanism. Surfaced (not caused) by this branch's gsd-test
runs loading the bench; unrelated to the markdown-parsing changes but fixed in
place per the no-flaky-tests rule.

2cbf186420 chore(#2143): fail-loud Result + per-surface write-set contract — Phase 3 (#2251)
* chore(#2143): fail-loud Result + per-surface write-set contract — Phase 3

Phase 3 of epic #2143 (ADR-2143 §5/§6). The three target bugs (#2140, #2112,
#2118) were already fixed tactically on next; this introduces the reusable
structural contracts and rewires the primary #2140 site onto them.

- src/write-set.cts (new): the parse `Result<T> = {ok,value|reason}` (§5) and the
  per-surface write-set (`WriteOutcome {surface, applied, requirement?}`,
  `WriteSet`, `writeSetComplete`) (§6). markdown-table.cts now imports + re-exports
  `Result` from here (single source; distinct from command-routing-hub's Result).
- requirements mark-complete (src/milestone.cts): returns a PER-REQUIREMENT,
  per-surface write-set; `write_set_complete` is true only if every surface of
  every requirement applied — structurally forbidding the #2140 OR-into-one-flag
  masking, including across a multi-ID batch (adversarial-review regression).
  Pre-existing output fields unchanged (behaviour-preserving; #2140 already fixed).
- deriveProgressFromRoadmap (src/phase-lifecycle.cts): removed the vestigial
  null-swallowing try/catch (findTableWithColumns never throws) — ADR §5 no-swallow;
  RoadmapProgress return contract unchanged.
- commit --files (#2112) and milestone complete --dry-run (#2118) left as-is
  (single-surface commit / pre-mutation preview — not genuine multi-surface writes).

481f00e38a fix(#2118): honor --dry-run in milestone complete with zero-mutation preview (#2155)
* fix(2118): honor --dry-run in milestone complete with zero-mutation preview

milestone complete treated --dry-run as a no-op: the flag was neither
parsed nor rejected, so a caller who expected a preview instead
triggered the full destructive mutation (archive phases → move audit
artifacts → rewrite STATE.md) with no way to back out.

Fix (option 2 from the issue): add dryRun to MilestoneCompleteOptions,
parse --dry-run in the dispatcher, and return a JSON preview plan
(would_archive, would_update) after the read-only stats gathering but
before any mutations. Also gated platformEnsureDir on !dryRun so the
archive directory is not created during preview.

3 regression tests: no-mutation happy path, --no-archive-phases combo,
and --force bypass combo.

The milestone --dry-run fix changes gsd-core/bin/gsd-tools.cjs; qwen.json
(missed at authoring) and pi.json (added on next, never carried the fix)
were the only two runtime fixtures still holding the pre-fix hash. All
other runtimes already reflect the change. Regenerated via the sanctioned
gen-golden-install-parity script.

* fix(#2118): surface accomplishments in dry-run preview; fix --dry-run --raw

Orthogonal review findings on the --dry-run preview:
- The preview omitted the already-computed accomplishments (the primary
  MILESTONES.md content a real run writes); surface it as a top-level field,
  mirroring the real-run result.
- `--dry-run --raw` discarded the structured payload and printed the literal
  string "dry-run"; drop the raw-value arg so --raw emits the full preview
  JSON, matching the real-run output() call.
Adds tests: --dry-run --raw is parseable JSON, preview includes accomplishments,
and --dry-run --force is proven zero-mutation.

87ab4a4896 fix(#2140): distinguish checkbox-only reconcile from full in requirements mark-complete
cmdRequirementsMarkComplete OR-ed its two write surfaces (the - [ ] checkbox and
the | ID | ... | Pending | traceability row) into one 'found' flag. When the
checkbox matched and no table row did, it reported the same 'updated: true,
marked_complete: [ID]' payload as a full reconcile — while the traceability row
stayed Pending. The already_complete branch used OR (checkbox done OR row done),
so re-running on the half-written file classified the drift as already_complete
and moved on. audit-milestone (which reads the table) still saw Pending.

- Track the two surfaces separately (checkboxHit / tableHit).
- Add a 'table_unmatched' bucket: an ID whose checkbox reconciled (this run or
  before) but whose traceability table has no row for it — only when a table
  actually exists (a table-less REQUIREMENTS.md is legitimate).
- Fix the already_complete predicate: fully reconciled requires the row Complete,
  OR the checkbox done with NO table — a [x] checkbox with an absent/Pending row
  is partial, not done.
- A table-less REQUIREMENTS.md stays a clean success (the OR's legitimate use).

The invariant: a not-fully-applied requirement no longer returns a payload
indistinguishable from a fully-applied one.

71edb27fe1 fix(#2136): route operator-facing date fields through local clock day
clock.today() derived the calendar day by slicing a UTC ISO instant
(nowIso().split('T')[0]), so in any negative-UTC-offset zone during UTC's early
hours last_activity named a day the operator had not reached yet — ahead of
last_updated's local date, written by the same call.

- Add Clock.localToday(): host-local YYYY-MM-DD via getMonth/getDate/
  getFullYear, honoring the same GSD_NOW_MS pin as today()/nowIso().
- Route operator-facing date-only fields through localToday(): last_activity
  (state-transition ×7, state.cts), roadmap 'completed <date>' (phase.cts,
  roadmap.cts), milestone completion date (milestone.cts), todo/scaffold
  completion (commands.cts — now threaded through the realClock seam).

c1cd43a39f fix(#2128): bound the phase-tag clause to {0,200} — kill quadratic ReDoS
The canonical OPTIONAL_PHASE_TAG_SOURCE tag clause `(?:\s*\([^)\n]*\))?` (and its
inlined literal mirrors across 11 modules) had an UNBOUNDED body, making the
optional-group + /g header scan quadratic on adversarial ROADMAP.md/STATE.md — a
long run of `(` after a header ran ~18.8s at 1.7MB. Bound the body to {0,200} in
the constant AND every mirror in lockstep (the #1729 "both forms change together"
contract), so the scan is linear: the same 1.7MB input now resolves in ~9ms
(measured), while real tags (a handful of chars) still match and a 201-char tag
is rejected. Added a #2128 boundary regression to the #1729 suite.

Pre-existing (byte-identical before/after the Phase 4 migrations); folded in at
maintainer direction rather than deferred.

dfad3a7510 refactor(#2128): single-source 23 phase-token re-derivations; sanction 14 context-specific sites
Route 23 literal re-derivations of the canonical phase-number token through
phase-id.cjs `PHASE_NUMBER_TOKEN_SOURCE` (via new RegExp). Each conversion was
proven BYTE-IDENTICAL (old.source === new.source && old.flags === new.flags), so
the runtime regexes are unchanged — zero behavior change by construction.

The remaining 14 phase-token sites are genuine but context-specific and stay
literal with a `// phase-id-owner: <reason>` sanction: dir-name parses whose
dash-continuation semantics differ from extractPhaseToken, and the [A-Za-z]
case-variant / [.-] dot-or-dash separator forms that are not source-byte-equal
to the canonical token.

Scanner (`npm run check:phase-id-drift`) is now green.

e2bfe4dc67 fix(#1993): milestone --ws requirements archive header points at workstream path (#2015)
* fix(#1993): milestone --ws requirements archive header points at workstream path

The requirements archive header hardcoded the root .planning/REQUIREMENTS.md
path, so a workstream (--ws) archive pointed readers at the wrong file even
though #1917 fixed the archive LOCATIONS to land inside the workstream.

Derive the display path from the same workstream-aware reqPath the writer
already uses (path.relative(cwd, reqPath)). Root behavior is byte-identical
('.planning/REQUIREMENTS.md'); the --ws case now correctly reads
'.planning/workstreams/<ws>/REQUIREMENTS.md'.

- src/milestone.cts: reqDisplay interpolation in the archive header.
- tests/milestone.test.cjs: #1993 regression in the #1911 --ws block — header
  references the workstream path, not the root literal.

12b35eeeaf fix(#1729): resolve phase headers with a pre-colon parenthetical tag (#1765)
* fix(#1729): resolve phase headers with a pre-colon parenthetical tag

A phase header may carry a parenthetical tag between the number and the
colon, e.g. `### Phase 26 (Cluster B): Title`. Every phase-header regex
built `Phase\s+<num>` immediately against the colon delimiter, so the
tagged phase was invisible: the resolver returned found:false and, just
as bad, the capture-all enumeration/parse paths (roadmap analyze,
milestone listing + milestone-scope filter, verify, init/import, state
total_phases, validate, the command router, preamble stripping, and the
phase-remove renumbering rewrite) silently dropped, miscounted, or
failed to renumber it — wrong phase_count, progress_percent, next_phase,
or corrupt numbering after a removal.

The fix tolerates the tag at the header seam. Parameterized resolver
sites compose the exported OPTIONAL_PHASE_TAG_SOURCE fragment; literal
enumeration sites inline its character-for-character mirror
`(?:\s*\([^)\n]*\))?`, placed immediately before the colon so it cannot
alter an existing match (optional, single-line, one paren pair, no
capture-group shift). In the renumber-on-removal rewrite the tag is
folded into the re-emitted suffix capture so it survives verbatim. Both
forms are documented to change together and a drift-guard test asserts
their behavioral equivalence over a header corpus.

Deliberately excluded: roadmap-upgrade.cts (legacy one-time migration),
where tolerating the tag would silently drop it on header rewrite — that
needs its own data-preserving treatment. Known boundaries left for
follow-up: checklist/bullet-style phase entries (`- [ ] Phase N (tag):`)
and a malformed space-before-colon variant, both pre-existing.

Validated empirically against the issue's reproduction: `roadmap
get-phase 26` resolves and `roadmap analyze` lists Phase 26 with the tag
excluded from the name (phase_count 2, next 26); an all-tagged versioned
roadmap now scopes correctly instead of falling back to a pass-all
filter. Regression coverage in tests/phase.test.cjs asserts resolver
parity (pre- vs post-colon), padding tolerance (#3537), decimal
sub-phases, no cross-phase false match, the shared seam, enumeration
coherence, renumber-preserves-tag, and seam/mirror drift. Full unit
suite green (7291 pass, 0 fail); eslint + regression-name +
resolution-provenance + changeset lints pass. Reviewed by Codex
(no critical/high; the two enumeration misses it surfaced are folded in).

92091d71f2 fix(#1871): wire phase archival end-to-end (phases archive cmd + default + atomic) (#1924)
Follow-up to #1919 (archive-then-remove core). Closes the remaining #1871
acceptance criteria so phase history is preserved across the full milestone
lifecycle, not just at phases.clear:

- #2 src/milestone.cts + src/phases-command-router.cts: extract shared
  archivePhaseDirectories() helper; add cmdPhasesArchive (the previously
  half-wired phases.archive alias now routes instead of erroring Unknown).
- #4 gsd-tools.cjs + src/milestone.cts: milestone complete archives phase
  dirs by default (--no-archive-phases opts out; --archive-phases is now a
  harmless no-op). complete-milestone.md updated to drop the redundant manual
  Yes/Skip archive prompt.
- #3 gsd-core/workflows/new-milestone.md: §6 stages the archive move + source
  removal (git add .planning/milestones/ .planning/phases/) in the same commit
  as the milestone start, so the archive lands atomically — no orphaned
  uncommitted deletions, no un-archived dirs inherited.
- docs/CLI-TOOLS.md (+ ja/zh/ko/pt) + help/modes/full.md: flag accuracy.
- tests: phases archive command (#2) + milestone complete default archive /
  --no-archive-phases opt-out (#4). Goldens + workflow size baseline refreshed.

5195a36cc5 fix(#1871): phases clear archives dirs instead of destroying them (#1919)
cmdPhasesClear hard-deleted committed phase directories (rmSync) with no
archive, so browsable phase history was silently lost at a milestone switch.
The #1447 dirty-tree guard was a no-op for the common committed case (a clean
tree passes the guard, then rmSync destroyed the dirs, leaving orphaned
uncommitted deletions and no archive).

Archive-then-remove: move each non-999 phase dir to
milestones/<version>-phases/ (version from getMilestoneInfo; timestamp
fallback; collision-safe) using retryRenameSync — mirroring the existing
archivePhases path in cmdMilestoneComplete. The #1447 uncommitted-changes
guard is retained as a secondary backstop.

Tests in tests/new-milestone-clear-phases.test.cjs updated: phase content is
asserted to SURVIVE in milestones/*-phases/ (archived), not be destroyed —
including the committed-dirs case that previously codified the no-op.

Closes #1871

88da609b3e fix(#1911): milestone complete --ws archives to the workstream (#1917)
cmdMilestoneComplete hardcoded three archive paths to root .planning/
while its siblings (roadmap/requirements/state/phases) used workstream-aware
planningPaths. So `milestone complete <v> --ws <name>` scattered its archive
into root and never created workstream-local milestones/.

Derive the archive base from the workstream-aware planning root:
- milestonesPath / archiveDir / auditFile now use planningPaths(cwd).planning
- flat mode (no --ws) is a no-op (planningPaths(cwd).planning == root .planning)

Regression in tests/milestone.test.cjs: --ws archives into the workstream
milestones dir, not root.

3ceb83329d refactor(#1789): ADR-1769 Phase 5 — milestoneComplete migration (#1790)
Migrate the STATE.md write path inside cmdMilestoneComplete (milestone.cts)
onto the STATE.md Transition Module substrate (ADR-1769, epic #1769).

- Add {kind: 'milestoneComplete'} to StateTransitionIntent, with
  milestoneCompleteCore in src/state-transition.cts (consulting the
  field-classification table). Owns the closure write: Status
  ('<version> milestone complete'), Last Activity, Last Activity Description,
  a Current Position reset to 'Awaiting next milestone', and an Operator Next
  Steps reset pointing at the next-milestone command.
- Collapse the inline STATE.md transform in cmdMilestoneComplete to a
  transitionCore dispatch. The adapter retains writeStateMd (lock + steady-state
  syncStateFrontmatter post-sync) and resolves the runtime-specific
  next-milestone slash command, injecting it via intent.nextMilestoneCommand.
- The two section resets carry their pre-seam allow-adhoc-markdown waivers
  (regex semantics pinned by existing tests; pending collectSection #1372).
- realClock.today() is byte-identical to milestone.cts's local today
  (both new Date().toISOString().split('T')[0]).
- Characterization tests pin field updates, both section resets (replace +
  insert paths), and frontmatter #1255 parity.

All 66 transition + milestone + state tests pass.

Closes #1789

871621c3c8 feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6) (#1742)
* feat(#1740): require-fs-op-fallback production AST rule + Windows transient-lock retry (Phase 6)

ADR-1703 Phase 6 of the cross-platform portability epic (#1702). Adds the
second production-code portability AST rule + the ADR-mandated glob expansion
to bin/install.js and scripts/build-hooks.js.

- eslint-rules/require-fs-op-fallback.cjs: flags an unguarded fs.rename /
  fs.renameSync (the atomic-publish primitive named first in
  DEFECT.WINDOWS-FS-OPS.symptom) that is NOT inside a try/catch whose handler
  references a transient errno ('EPERM'/'EBUSY'/'EACCES' or a *RETRY_ERRNOS
  set) AND NOT behind a Windows platform guard. A catch that silently swallows
  or cleans-up-and-rethrows without an errno check does NOT satisfy the
  defect's 'never silently swallow' clause. copyFile/unlink are deliberately
  not flagged (they are the fallback primitives per the defect's own
  fix-forward). Scope narrowed to rename per Phase 5's precision discipline;
  documented on #1740.

- src/shell-command-projection.cts: export retryRenameSync(from, to) — the
  drop-in bounded-retry helper over the existing atomicRenameWithRetry.

- 27 bare fs.renameSync sites across 11 modules routed through retryRenameSync
  (capability-lifecycle/lock/source, installer-migrations, milestone, phase,
  planning-workspace, roadmap-upgrade, runtime-hooks-surface, state,
  workstream). Idempotent on POSIX; resilient to AV/indexer transient locks
  on Windows.

- eslint.config.mjs: register rule at error on src/**/*.cts; new focused
  portability-rules block covering bin/install.js + scripts/build-hooks.js
  (ADR-1703 L124-126 glob expansion — both files are compliant: zero
  rename violations).

- tests: 15-case RuleTester suite; portability-rule-disable-ban extended
  (PROTECTED_RULES + scans bin/install.js/build-hooks.js with shebang
  handling); ci-test-scope portability-lint selection rule.

- CONTEXT.md DEFECT.WINDOWS-FS-OPS predicate rewritten to point at the rule;
  docs/contributing/cross-platform-portability-rules.md reference + how-to.

Closes #1740

* chore(#1740): backfill changeset pr:1742

* fix(#1740): tighten require-fs-op-fallback precision (codex review HIGH-1/HIGH-2)

Addresses two false-negative findings from the codex (gpt-5.5/high)
adversarial review of PR #1742:

HIGH-1 — a catch that REFERENCES a transient errno but only rethrows (no
retry/fallback) was marked compliant. The DEFECT.WINDOWS-FS-OPS fix-forward
requires retry, not just recognition. Fix: catchHandlerHasRetrySignal now
requires a loop `continue` backedge OR a `return <call>` delegation; a bare
rethrow is flagged. The misleading `/* retry logic */` valid test is replaced
with a real retry loop, and the rethrow-only shape is added as invalid.

HIGH-2 — the nested-try ancestor walk treated an OUTER errno-catch as
protecting the rename even when an INNER catch intercepted/swallowed the error
(the outer catch is unreachable). Fix: isInsideTransientErrnoTryCatch now stops
at the NEAREST enclosing TryStatement WITH A CATCH HANDLER whose block contains
the rename (try-finally is skipped — it doesn't catch); outer catches are no
longer consulted. The unsound nested-try valid test is converted to invalid,
and a try-finally-skipped valid case is added.

Verified: 17 RuleTester cases pass; zero new production violations (the 27
fixed sites use retryRenameSync; the real retry loops — atomicRenameWithRetry,
capability-ledger/consent, build-hooks — remain compliant via continue/errno);
lint:ci green; disable-ban + vocab-drift green.

6414249d25 fix(#1580): exclude 0/999 sentinels from milestone-complete guard and roadmap analyze (#1691)
* fix(#1580): exclude 0/999 sentinels from milestone-complete guard and roadmap analyze

Closed #1445 added the `^999` backlog-sentinel exclusion to the progress
denominators but missed two other resolvers, leaving two user-facing failures
live on a milestone whose only directory-less ROADMAP heading is a backlog
sentinel:

(A) `milestone complete` was blocked by the unstarted-phase guard in
    src/milestone.cts — it flagged `### Phase 999: Backlog` as an unstarted
    phase and refused to close a fully-shipped milestone without --force.
(B) `roadmap analyze` (src/roadmap.cts) counted the sentinel in phase_count
    and routed `next_phase` straight into Phase 999.

Both now skip Phase 0 (pre-milestone) and Phase 999 (backlog) sentinels,
mirroring the engine-wide convention (phase-id getMilestoneFromPhaseId,
roadmap-command-router SENTINELS, the #1445 progress filters). Symptom (C)
(state.cts total_phases) was already fixed inline by #1445/#1514 and is out
of scope here.

Regression coverage folded into tests/fix-1445-*.test.cjs (scenarios C and D);
updated tests/bug-978 fixture to use a real unstarted phase (Phase 2) instead
of a 999 sentinel, since the sentinel is now correctly excluded from that guard.

ba3181204b fix(#1422,#1447): fix sub_repos/.git precedence; guard uncommitted data in new-milestone (#1484)
* fix(#1422): sub_repos config takes precedence over .git in findProjectRoot

When heuristic-3 (.git + parent .planning/) fires, do a lookahead walk
over ancestors above the matching parent to check if any further ancestor
has a sub_repos entry that explicitly claims the starting directory. If
found, return that ancestor instead — explicit config wins over the
implicit .git signal.

Regression tests updated: the heuristic-3 precedence test now asserts the
correct new behavior (sub_repos wins), and two additional coverage cases
added (startDir directly in sub_repo child, and startDir nested 2+ levels
inside the child).

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix(#1447): guard against uncommitted changes before deleting phase dirs in new-milestone

cmdPhasesClear now runs `git status --porcelain <phasesDir>` before
executing any rmSync. If uncommitted changes are detected it calls
error() and aborts, preventing silent data loss when new-milestone's
§6 "phases.clear --confirm" fires before the operator has archived
or committed outgoing phase work.

A new --force flag is added to bypass the guard for callers that have
already verified archival is done (or explicitly accept the loss).
When git is unavailable or the directory is not inside a git repo the
guard silently skips, preserving the existing behaviour for non-git
projects.

Five new regression tests cover: untracked files abort, staged-but-
uncommitted abort, --force bypasses, committed files pass, non-git
project passes without guard.

* refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete)

After T0–T6 nothing imports core, so retire the spine and its scaffolding:
- delete src/core.cts (and the gitignored gsd-core/bin/lib/core.cjs artifact;
  remove its .gitignore + eslint-ignore entries)
- delete scripts/lint-core-spine-imports.cjs + its allowlist; drop it from the
  package.json lint:ci chain
- regenerate docs/INVENTORY-MANIFEST.json (drops the core.cjs surface)
- sweep stale references: CONTEXT.md glossary back-compat clauses (spine retired,
  callers import the leaf directly), planning-config.md CONFIG_DEFAULTS owner,
  and false present-tense core.cjs claims in leaf-module docstrings

The ADR-857 decomposition is complete: the former Core god-module is fully
dissolved into its leaf modules; no re-export spine remains. No behaviour change.

Closes #1294

* fix(#1294): migrate the computed-path core.cjs importers the literal grep missed

bin/install.js used require(path.join(_gsdLibDir, 'core.cjs')) (a computed
path, and bin/install.js was never in the convergence lint's scan roots), and
~8 test files referenced core.cjs via path.join/readFileSync/existsSync/FILE_ARG
forms the literal-string migration grep missed. Route install.js's symbols to
their leaves (RUNTIME_PROFILE_MAP->model-catalog, resolveTierEntry/EFFORT_SET->
model-resolver) and repoint/adjust the test references to the leaves. Recovers
the 161 'Cannot find module core.cjs' failures from the spine deletion.

a5f213e73e refactor(#1281): T2 — migrate 12 single-leaf callers off the core spine (batch 1) (#1282)
Per the T1 design rubber-duck, batch by FILE so each tranche drops
convergence-lint allowlist entries. Migrate 12 files' core imports to the
leaf modules directly (behaviour-identical — leaves are the objects core
re-exports by reference):
- io (output/error/ERROR_REASON): agent-command-router, capability-state,
  capability-writer, frontmatter, gsd2-import, learnings, loop-resolver,
  task-command-router
- roadmap-command-router -> config-loader; workstream-inventory -> core-utils
- milestone, verify -> their full leaf sets (both were multi-leaf, not
  single-leaf as first scoped; migrated completely)

All 12 files now import zero core symbols and are removed from the
allowlist (30 -> 18). core.cts re-exports untouched (still serve the
remaining 18 files); teardown is T-final. Stale core.cjs docstrings in the
migrated files corrected to reference io.cjs. No behaviour change.

* enhancement(#537): migrate code-review-flags to TS source of truth

Collapse the hand-written get-shit-done/bin/lib/code-review-flags.cjs to a
TypeScript source of truth (src/code-review-flags.cts), compiled by tsc to a
gitignored .cjs build artifact at the same path, per ADR-457 (build-at-publish).
Second module after the semver-compare pilot (#541).

Behaviour is preserved byte-for-behaviour (characterization test added in
tests/code-review-flags.test.cjs locks the parser quirks). Adds compile-time
type checking: CodeReviewFlags interface + CodeReviewWorkflow literal union.
The require() path is unchanged, so code-review.md and the bug-3727 test keep
working. The emitted .cjs is gitignored and eslint-ignored, mirroring the pilot.

* enhancement(#537): migrate commands + state hubs to TS (batch 14)

ADR-457 build-at-publish: commands (1305 LOC), state (2074 LOC, 17 dependents).
All exports preserved; inner requires kept non-hoisted where load-order matters
(install.js, per-call security); acquireStateLock cast inlined to preserve the
err.code source token a structural test inspects. Behaviour preserved; suite
green across all shards (only the 4 local gpg-env failures). Wave 6 complete.

* enhancement(#537): migrate milestone to TS (batch 15a, hand-authored)

ADR-457 build-at-publish: milestone -> src/milestone.cts. Authored directly
(subagent capacity was unavailable). Also relaxes core.output()'s 3rd param to
optional, matching its real always-optional call contract (unblocks remaining
2-arg output callers). Behaviour preserved; suite green across all shards
(only the 4 local gpg-env failures).

* enhancement(#537): migrate phase, verify, init to TS (batch 15, final modules)

ADR-457 build-at-publish, Wave 7 (the last hubs): phase (1608 LOC), verify
(1615), init (2113). Adds src/package-identity.d.cts so verify can import the
permanently value-baked package-identity.cjs under strict TS.

Fixes two regressions the migration introduced in verify: restore
cmdValidateHealth's `return result` (callers/tests read result.warnings — it is
NOT side-effect-only), and make the bug-3384 source-pattern test tolerant of the
tsc-compiled bracket-notation form of the git_list_failed->W020 branch (behaviour
intact). Full suite green across all shards (only the 4 local gpg-env failures);
lint 0 errors. All 86 migratable bin/lib modules are now TypeScript sources.

* chore(#537): finalize ADR-457 migration — retire tsconfig.lint.json

All hand-written bin/lib/*.cjs are now src/*.cts sources, so the checkJs
stopgap tsconfig.lint.json (unused; not wired into eslint, scripts, or CI) is
deleted per ADR-457's final step. Also gitignore the tsc-generated
config-types.cjs (was still committed) for consistency with every other
emitted artifact. package-identity.cjs stays value-baked (declared via
src/package-identity.d.cts). Suite green; #551 ESLint-coverage test green.

* fix(#537): add prepare script so unpacked/git installs build bin/lib artifacts

ADR-457 build-at-publish: bin/lib/*.cjs are now gitignored, built by tsc. The
prepack/prepublishOnly hooks cover `npm pack`/publish, but `npm install -g
<dir>` and git installs run the `prepare` lifecycle — which was missing — so the
unpacked install shipped without the compiled .cjs and failed at startup with
"Cannot find module './lib/core.cjs'" (caught by the smoke-unpacked CI job).
Add `prepare` mirroring prepublishOnly (build:lib + build:hooks). prepare does
NOT run for registry consumers (they get the pre-built tarball), only for
source/local/pack installs.

* fix(#537): make CI build/lockfile checks work with gitignored bin/lib artifacts

ADR-457 build-at-publish exposed two CI assumptions that bin/lib/*.cjs are
always present on disk:
- check:env's lockfile-sync ran `npm ci --dry-run`, which now triggers the
  `prepare` build (tsc) — but it runs before deps are installed, so tsc is
  absent and it misreported the lockfile as out of sync. Add --ignore-scripts
  (a lockfile check must not build).
- the lint-tests job installs with --ignore-scripts (no prepare build), but
  lint:skill-deps require()s the built install-profiles.cjs. Add an explicit
  `npm run build:lib` step after install.

* fix(#537): narrow prepare to build:lib only (unbreak packed-smoke pack step)

prepare running build:hooks emitted "✓ Copying ..." stdout during `npm pack`,
which the install-smoke "Pack root tarball" step captures into $GITHUB_OUTPUT —
breaking it with "Invalid format". build:lib (tsc) is silent on success and is
all the unpacked/source install needs (the smoke-unpacked assertions exercise
gsd-tools, i.e. bin/lib, and tolerate hook setup with `|| true`). Matches
prepack. build:hooks still runs on prepublishOnly for real publishes.

* fix(#537): wire Stryker mutation gate to build-at-publish layout

The gate scored 0.00 because it mutated changed bin/lib/*.cjs that (a) were
generated artifacts and (b) included modules with no coverage in the command's
test set. Rework: mutation.yml now derives changed COVERED modules from
src/*.cts and maps them to their built bin/lib/*.cjs; Stryker mutates those
built artifacts with a no-rebuild command (mutating src/*.cts + per-mutant tsc
was ~3x over the 30-min CI budget).

NOTE: with the gate now correctly measuring the covered modules, their actual
mutation score is 42.94% (< break 50) — a pre-existing test-coverage gap
(adr-parser/prompt-budget/etc.), not introduced by this behaviour-preserving
migration. Reaching 50 needs more tests, a threshold/scope change, or a waiver —
a maintainer decision.

* test(#537): raise mutation coverage of covered modules above the 50 gate

Adds focused example-based unit tests that kill surviving mutants in the two
lowest-scoring covered modules:
- tests/prompt-budget.unit.test.cjs (112 tests): 17.9% -> 97.9%
- tests/adr-parser.unit.test.cjs (205 tests): 44.7% -> 89.4%
Both wired into stryker.config.mjs's command. Fresh full run over the 6 covered
modules now scores 82.25% (>= break 50); every covered module is >= 68%.

* enhancement(#537,#609): parallelize mutation gate via dynamic per-module matrix

The serial Stryker run timed out at 30 min once the migration's added tests
made every mutant re-run ~300 tests. Replace it with a dynamic matrix so the
gate completes well under budget — folded into this PR (was tracked as #609)
because it's a prerequisite for this PR's mutation gate to pass.

- scripts/mutation-matrix.cjs: single source of truth (covered-module -> test
  files) computing changed covered modules from git diff -> {has_work, matrix}.
- mutation.yml: detect -> dynamic `matrix: fromJSON(...)` mutate job (one
  parallel shard per changed module, scoped via MUTATION_TEST_CMD to only that
  module's tests, 15-min/shard) -> summary job that KEEPS the legacy check name
  "Stryker mutation score (changed files only)" so branch protection is
  unchanged. Per-shard jobs report as "Stryker (<module>)".
- stryker.config.mjs: commandRunner.command reads MUTATION_TEST_CMD (falls back
  to the full command locally).

Closes #609.

* test(#537,#609): give each mutation shard ≥50% on its own tests; drop blacksmith note

Per-module sharding revealed that active-workstream-store (46.5%) and
frontmatter (7.4%) only cleared 50% in the old serial run via timeout-noise from
the bloated 300-test command; on their own tests they were below the gate. Add
focused unit tests:
- tests/active-workstream-store.unit.test.cjs (115 tests): 46.5% -> 81.9%
- tests/frontmatter.unit.test.cjs (165 tests): 7.4% -> 63.4%
Both wired into scripts/mutation-matrix.cjs (per-module test map) and
stryker.config.mjs DEFAULT_TEST_CMD. All 6 covered modules now clear break:50
with only their own tests (config-schema/context-utilization/prompt-budget/
adr-parser already did). Also removes the leftover blacksmith TODO comment —
GitHub-hosted runners only; speed comes from parallel per-module shards.

* test(#537,#609): strengthen prompt-budget tests to clear the gate on its own tests

prompt-budget scored 39.58% when mutation-tested with ONLY its own tests (the
way the per-module CI shard runs it) — an earlier ~98% reading was inflated by
accidentally running the full multi-module command. Add 96 targeted tests to
tests/prompt-budget.unit.test.cjs (exact note-template text, plan-truncation
arithmetic/percentages, drop-block strings, noteInjected/hardFailed booleans):
scoped score 39.58% -> 68.75% (>= break 50). All 6 covered modules now clear
the gate on their own tests.
