a9a7a328e6 refactor: hard-fork GSD -> MSD (Make Software Done)
Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.

Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.

d7b5b2c2b6 fix(#4906): migrate the ROADMAP.md Plans: line onto the PlanningDoc seam — Phase 2 (#4933)
* feat(#4906): migrate the ROADMAP.md **Plans:** line onto the PlanningDoc seam

Phase 2 of epic #4906. Migrates the two writers of ROADMAP.md's Plans field onto
the seam ADR-4910 locks, and deletes both bespoke regexes per Decision 2 — a
correct copy of a rule the seam now owns is the same divergence risk as an
incorrect one.

src/phase.cts's mutateMilestonePhase carried planCountBodyPattern, one capture
group, replace-to-end-of-line: this is #4852, still live before this change.
src/roadmap.cts's cmdRoadmapUpdatePlanProgress carried the correct three-arm
sibling (the #2853/#3584 correction) that phase.cts never adopted. Both now call
findField/setFieldValue/serialize against a PlanningDoc parsed from the same
milestone/phase-confined substring their existing withPhaseSection /
replaceInCurrentMilestone wrappers already compute — those confinement
wrappers are unchanged, only the field-write mechanism inside them moved.

Verified end-to-end through the real commands against real fixtures, not
against an isolated reimplementation of the classification logic:
cmdRoadmapUpdatePlanProgress and cmdPhaseComplete both preserve a trailing
human annotation across a real count rewrite, and both leave a bracketed
human annotation (the #3584 Finding A discriminator) untouched.

Found and fixed inline, in the already-merged src/planning-document.cts,
rather than deferred: BOLD_FIELD_RE recognized only **Label:** (colon inside
the closing bold). gsd-core/templates/roadmap.md ships every field, Plans
included, as **Label**: (colon outside) -- migrating roadmap.cts onto the
seam as it stood would have silently regressed real generated ROADMAP.md
files back to the bug this migration exists to remove. Widened to recognize
both spellings; deliberately NOT widened to a bare unbolded Label: form,
which would register ordinary prose as a spurious field.

roadmap.cts's writer also recognizes a bare singular/plural count (1 plan /
3 plans, no fraction) as an existing count token to overwrite, not template-
placeholder or freeform prose -- the template's own single-plan-phase shape
and #3584 Finding B's fix. Preserved exactly; this shape is easy to drop by
only porting the more common fraction form.

Two of Phase 2's three originally-cited defects turned out to be already
fixed on next, independent of this epic, and are struck via a dated ADR
amendment rather than silently narrowed: #4862 (stateReplaceField's own
anchoring hardening already preserves sibling fields) and #4499
(spliceFrontmatter's per-key preservation already keeps block sequences
byte-identical). Both reproduced against the built module before being
struck, not assumed. STATE.md's field-write engine is re-scoped out of this
phase entirely -- not because of its get_impact rating alone (measured the
same way, the two sites THIS phase keeps are also CRITICAL, and an earlier
draft of the amendment claimed otherwise without checking; corrected) but
because updateCore is a multi-field transaction with frontmatter sync and
preservation reconciliation that does not map onto PlanningDoc's node model,
where migrating it would mean designing that model, not calling an existing
seam function.

* fix(#4906): preserve a trailing annotation with no em-dash separator

Test authoring surfaced a real regression against an existing #3584 fixture:
`**Plans**: 0/1 plans executed (11-16 are gap closure from VERIFICATION)` -- a
parenthetical annotation glued on with a bare space, no em-dash -- was left
completely untouched by the migrated code instead of being rewritten with the
count updated and the parenthetical preserved.

Root cause: planning-document.cts's parseBoldFieldLine splits a field's value
from its trailing annotation only on the literal " -- " separator. An
em-dash-separated annotation already lives outside `value` in `trailingSpan`,
untouched by setFieldValue regardless -- that path was never broken. A
parenthetical with no em-dash has nowhere to go but inside `value`, and the
migrated classification required the WHOLE value to match a count-token shape
exactly, so this case fell into "leave untouched."

Fixed in the migrated call sites, not in the seam: prefix-match the count
token against the field's current value, then re-glue whatever textual suffix
follows WITHIN that value onto the new count text before writing. Correct for
both shapes with no special-casing -- the em-dash case's suffix-within-value
is empty by construction (the annotation already lives outside value), the
parenthetical case's suffix is exactly the glued content, preserved verbatim.

Deliberately not fixed by widening planning-document.cts's separator grammar
to also recognize a bare-space-then-parenthesis: that seam is already-merged
and already-tested, and guessing at an open-ended set of annotation shapes at
the seam level is exactly what isTemplatePlaceholder already avoids by
staying caller-side. "What counts as a Plans-field count token" is domain
knowledge about this one field.

phase.cts's writePlansField had no arm-2/arm-3 classification before this
migration -- its original regex unconditionally overwrote whatever value was
present. That unconditional-overwrite behavior is preserved exactly for
values with no recognizable count-token prefix; only the recognized-count
case gained suffix preservation, matching what phase.cts actually did before.

Verified end-to-end via the real cmdRoadmapUpdatePlanProgress and
cmdPhaseComplete commands against real fixtures for both the parenthetical
and em-dash shapes at both sites.

* test(#4906): cover the migrated Plans-line writers at both sites

15 cases across tests/phase.test.cjs and tests/roadmap.test.cjs, one per row
of the phase test matrix, extending the existing describe blocks and helper
functions those files already use for these two commands rather than
building parallel fixtures.

Covers: trailing-prose preservation on a real count rewrite at both sites
(the #4852 regression, and the #2853/#3584 non-regression); zero-trailing-
content boundary; the bracketed-template-placeholder vs bracketed-human-
annotation discriminator (#3584 Finding A); a missing Plans field not
crashing either command; an unrelated unreadable sibling node in the same
confined section surfacing rather than corrupting the field; confinement
holding across sibling phases and milestones; a round trip through the
command's own read path; CRLF safety; and a parity assertion that both sites
now produce identical Plans-line text for identical inputs, proving one
shared mechanism rather than source-grepping for the deleted regex literals.

Authoring caught a real regression before it could land silently: an
existing #3584 fixture using a parenthetical annotation with no em-dash
separator failed against the first version of the migration. Reported rather
than edited to match the broken behavior -- see the paired fix commit. That
existing test needed no changes once the fix landed; its assertion was
verified independently against the real CLI before this commit.

* fix(#4906): give phase.cts's Plans writer the same arm-2/arm-3 classification as roadmap.cts

Isolated adversarial review (mandatory orthogonal review pass) executed
writePlansField against `[Deferred pending re-scope]` and the fresh-template
placeholder wording and found the first version of this migration kept
phase.cts's OLD unconditional-overwrite behavior for the no-count-prefix
case instead of adopting the same isTemplatePlaceholder / arm-3-untouched
classification roadmap.cts's sibling site already uses. A bracketed human
annotation was being silently rewritten to a new count -- a real
content-destroying regression against this phase's own design-doc behavior
table, not an accepted trade-off, and exactly the kind of divergence between
the two sites Decision 2's parity requirement exists to eliminate.

writePlansField now runs the same template-placeholder check and "no count
prefix and not a placeholder => leave untouched" branch before ever calling
setFieldValue. Added two site-1 tests (rows 4 and 6 of the phase test
matrix) mirroring the existing site-2 coverage for this exact discriminator.

* fix(#4906): restore plain (non-bold) Plans: line support and fix a test helper mismatch

gsd-test (mandatory verification, run before every push) surfaced two real
defects the migration's manual CLI checks had not caught:

1. #1163 regression: a hand-edited/pre-template ROADMAP.md can carry a PLAIN
   (non-bold) `Plans:` line rather than the canonical `**Plans**:`/
   `**Plans:**` bold field. The old deleted regexes tolerated this shape;
   the seam's BOLD_FIELD_RE is deliberately bold-only (widening it would
   register ordinary prose like "Note: see below" as a spurious field
   seam-wide), so the migrated writers silently no-op'd on it instead of
   updating the count -- a real, previously-tested behavior lost.

   Fixed with a caller-side fallback in both src/roadmap.cts (where the
   failing #1163 test lives) and src/phase.cts (added for parity, per
   Decision 2 -- the two sites should not diverge on which legacy shapes
   they tolerate): when findField finds no boldField Plans node, look for a
   plain `Plans:` line directly and apply the same arm-1/2/3 classification
   against it. This is domain knowledge about one field's legacy tolerated
   shape, the same class of thing isTemplatePlaceholder already keeps
   caller-side rather than seam grammar.

2. tests/roadmap.test.cjs's new rows 4/5 (site 2) seeded the colon-outside
   spelling (`**Plans**: ...`) but their plansLineIn() helper only matched
   colon-inside (`**Plans:**`), so both assertions compared against
   `undefined` regardless of whether the write logic was correct -- a
   test-authoring bug, not a source defect. Fixed the helper to recognize
   both BOLD_FIELD_RE spellings, matching what the production code actually
   supports.

Verified via a real gsd-test run before this fix (outcome: failed, 5
failures, all in tests/roadmap.test.cjs) and will be re-verified via a real
gsd-test run on this commit before push, per this repo's non-rationalization
rule: a red gate is fixed, never explained away.

d1d9ee85a5 feat(#4142): thread convention through the completion-path membership seam (#3644)
* 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
#{1,2} `[CODE.MM]` heading, including one bearing the SAME milestone id
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

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

lint:ci` deferred to the team lead's own run per instruction.

* 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

* 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.

Body text only; `type` and `pr` are untouched.

* 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.

* fix(#2761): three review-lens corrections to the merge resolution

Found by an adversarial pass over the re-homing, none caught by any gate.

1. planning-snapshot.cts — `phaseDirs` goes back to upstream's exact call,
   `listMilestonePhaseDirs(paths.phases, { cwd })`.

   The merge passed the resolved convention explicitly, on the belief it was a
   behaviour-preserving spelling of the lazy default. It is not. The lazy path
   resolves `resolvePhaseIdConvention(cwd, ws)` with this call's `ws`, which
   defaults to `null` — the PROJECT-only reading, no root fallback — while the
   `phaseIdConvention` field is resolved federated (workstream -> root). On a
   workstream repo whose ROOT opts into bracket and whose workstream config
   does not, those answers differ, so the explicit pass silently re-scoped
   `phaseDirs`. No test covered it in either direction (proven: reverting is
   green across all bracket + health-diagnostic + snapshot suites). PR-2 does
   not need that change, so it is dropped rather than kept untested. The
   federation guarantee is still delivered where it is observable — in the
   rules that read `snapshot.phaseIdConvention`.

2. planning-snapshot.cts — `buildRoadmapBracketIncoherencesField` decides
   file-readability BEFORE the convention gate, so `scope` means one thing on
   every repo. Ordered the other way, an absent ROADMAP.md reported COMPLETE on
   a legacy repo and UNREADABLE on a bracket one — the same "nothing to say"
   state wearing two scopes, which is exactly the non-answer/answer distinction
   ADR-3180 §8.1 gives `scope` to carry. No behaviour change (RULE_W021 does not
   read this scope); it removes an ambiguity a reader of that ADR would catch.

3. roadmap-disk-consistency.cts — `checkW006` reads
   `roadmapSentinelPhaseTokens` without its own scope guard. That is safe
   TODAY because one builder call produces it and `roadmapDeclaredPhases` from
   one `buildRoadmapPhaseVariants` result, so their scopes are yoked; the
   existing COMPLETE check covers both. Stated in a comment instead of left to
   co-location, since an UNREADABLE sentinel set degrades to "nothing is a
   sentinel", which ADDS W006 warnings rather than dropping them.

* 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

#3446's `findMilestoneScopeHeadingLines` is defined as a MIRROR of the
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
#3480 or this branch; out of scope here.

* 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): thread convention into the #3511 membership seam — bracket dirs scope like their legacy twins

Upstream #3511's isPhaseArtifact/scopeToPhase was structurally inert on
bracket directories: 3+-letter codes (GSD.02-…) fell into the zero-token
include-everything fail-safe (PROJECT_CODE_PREFIX_CAPTURE_RE_I strips
{CODE}-, not {CODE}.), and short digit-bearing codes (A1.02-…) into the
firstLetterPrefixed one — so every bracket dir read include-everything and
a cross-phase stray could complete a bracket phase, the exact
contamination #3511 shipped to prevent, still open on this PR's own
convention.

The seam now takes the same optional trailing convention its sibling
primitives do (ADR-2121 additive shape; gated on BRACKET_DIR_TOKEN_RE, the
one grammar owner shared with extractPhaseToken's bracket branch), through
a candidate-comparison core shared with the legacy path so the two cannot
drift. Threaded by the call sites that already hold the resolved
convention: the completion chain (isPhaseComplete ->
readVerificationStatus -> resolveVerificationFile, with a convention-aware
RESOLUTION token and a deliberately convention-less command-argument
token), buildStateFrontmatter, cmdStateSync, cmdStateValidate's S006/S007
scan, the planning snapshot, and roadmap analysis. Convention-less readers
(uat, audit, init, gap-checker, phase-locator) keep the documented
fail-safe — the follow-up slice.

The phase-counting fixture now writes what cmdScaffold writes
(phase-matched ${normalizePhaseName(phase)}-VERIFICATION.md) instead of a
hardcoded 01-VERIFICATION.md that #3511 correctly reads as a stray; the
stray shape is pinned deliberately in a new regression block (measured
pre-fix: [3,3,3,2,67] with the stray counted as completion) alongside
seam-level pins for BOTH fail-safe families, so neither the rename nor a
one-branch patch can stand in for the fix.

* fix(#2761): review round — gate the FILENAME reading on the convention too, ratify the M-NN twin-parity trade

Two-leg review of the seam thread (adversarial + upstream-fit, then an
adversarial re-verify of the fixes) found and this commit closes:

- Major: the convention gated only the DIRECTORY reading. A
  milestone-qualified artifact name (GSD.02-01-VERIFICATION.md — the layout
  the read-tolerance suite models) derives zero legacy token segments, so
  FIX 2's token-less containment admitted it into ANY bracket dir. Qualified
  stems now compare on bracketQualifiedKey — exact key, or the dotted
  sub-phase continuation (the round-2 verify caught strict equality dropping
  the dot arm: over-exclusion, the dangerous direction) — while a well-formed
  stem naming a different phase or milestone is excluded. Malformed
  qualified-shaped stems keep the documented include-everything fail-safe.
- Major, RATIFIED not changed: an M-NN-stem report (02-01-VERIFICATION.md in
  GSD.02-01-one) is excluded exactly as its legacy twin excludes the same
  file; migration-window artifact renaming belongs to the migrator slice
  (ADR-612). Pinned in tests with its legacy-twin control.
- Minor: the counting fixture's verificationNameFor now routes through the
  production normalizePhaseName (padding has a single owner), and its
  docstring states honestly which artifact layout it models.
- cmdRoadmapUpdatePlanProgress threads the convention into isPhaseComplete
  (ADR-3180 §7.4 read/write-path symmetry with the analyze site).

All pins carry measured pre-fix values. Convention-less paths swept
byte-identical (1,800 comparisons, 0 differences).

* fix(#2761): mark the round-11 decoy fixture incomplete so it doesn't need a phase token

The two round-11 BLOCKER tests (cmdMilestoneComplete / cmdStateUpdateProgress
enumeration) pass a `not-a-declared-phase` decoy directory to writeProject as
an implicitly-complete fixture entry. After threading convention through the
#3511 membership seam, verificationNameFor derives the scaffolder's real
verification filename from the directory's phase token — which the decoy,
by design, does not carry. Mark the decoy incomplete instead: the assertions
these tests pin (exclusion from would_archive.phases / stats.phases) don't
depend on the decoy having a VERIFICATION file at all.

* 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.

* 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.

* 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.

Full suite green (796/796 across the targeted adr-612 + roadmap-parser
+ state files); node scripts/lint-phase-id-drift.cjs clean; eslint
clean on both changed files.

* 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;
eslint clean on all changed files.

* 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
scripts/lint-phase-id-drift.cjs clean; eslint clean.

* 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
scripts/lint-phase-id-drift.cjs clean; node scripts/changeset/lint.cjs
ok.

* 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

* 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).

* 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

* 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.

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

-> 946/946 pass (942 + 4 new). Zero drift measured across the full F1-F12
corpus except F1 itself (F9/F10/F12 remain red, deferred to the

* 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

* 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

* 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.

* 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

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

* 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:

     ~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
clean.

* 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.

* 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.

Body text only; `type` and `pr` are untouched.

* 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).

The fragment's trailing backlink named #2761 — the delivered PR-2 sibling

the issue this PR actually closes. The PR body already carries the correct
`Closes #4142` with `Refs #2761` for lineage; only the changeset disagreed.

* docs(#4142): name phase complete and workstream-inventory in the unthreaded-caller disclosure

Round-4 review Major. The changeset's "still unthreaded" list named only the
aggregate scans (uat, audit, init projections, gap-checker, phase-locator) and
omitted two call sites that also stay on the include-everything fail-safe for
bracket directories after this PR:

- cmdPhaseComplete (src/phase.cts:3394,3405) — `phase complete`'s advisory
  UAT and VERIFICATION warning pre-scan calls scopeToPhase two-arg, so a
  bracket phase can still be warned about a cross-phase stray it does not own.
- src/workstream-inventory.cts:663 — calls isPhaseComplete, which this PR
  made convention-aware, without resolving a convention to pass it.

Because roadmap.cts's write path WAS threaded here on ADR-3180 section 7.4
read/write symmetry, leaving `phase complete` off both the code and the
disclosure was the omission most likely to be read as covered by "the same
protection #3511 already gives legacy directories". That claim is now scoped
to the call sites this PR threads, in both the changeset and the shipped
docs/CONFIGURATION.md cell, which carried the identical omission.

Disclosure only — no production code changed. Threading these two remains
follow-up-slice work alongside the epic's other convention-less readers.

8deb40722a fix(#4478): anchor collectAnalyzePhases's phase-heading regex to line start (#4578)
* fix(#4478): anchor collectAnalyzePhases's phase-heading regex to line start

phasePattern (src/roadmap.cts, backing `gsd-tools roadmap analyze`) had no
line anchor -- #{2,4} could match a `### Phase N:`-shaped mention ANYWHERE
the global regex scan reached: mid-sentence prose, inside a blockquote,
inside an inline code span (backtick-quoted on the same line, not a fenced
code block tokenizeHeadings would exclude). Any such line minted a phantom
phase entry, inflating phase_count and able to collide on a phase NUMBER
with a real heading nearby.

Two correctly-anchored reference implementations already exist for the
same heading grammar in this codebase: tokenizeHeadings
(src/markdown-sectionizer.cts:453) and findRoadmapPhaseInContent
(src/roadmap-parser.cts:1385), which anchors against the tokenizer's own
output. collectAnalyzePhases was the one path scanning raw content
directly instead. Anchored to line start with the same 0-3 leading-space
tolerance tokenizeHeadings uses (rather than routing through the
tokenizer, which the issue offers as the more thorough fix but which
would require re-deriving this function's bracket/number/name capture
groups and section-boundary lookup from tokenized output instead of a
single combined regex scan -- a materially larger refactor than a bug fix
warrants; the issue itself offers anchoring as the sufficient fallback).

Added coverage to the existing tests/roadmap.test.cjs "roadmap analyze
command" describe block (not a new file -- the roadmap module already
had 4 test files and lint-test-file-count.cjs's own remedy is to
consolidate, not add a 5th) against the issue's own 5-row prose-lookalike
table, its duplicate-number consequence, and a boundary case (a
legitimately-indented real heading must still count).

Independent code review on this same diff found one more consequence:
the "next heading" section-boundary lookup (nextHeader, a few lines
below phasePattern) lacked the SAME {0,3} leading-space tolerance --
a legitimately-indented NEXT phase heading was invisible to it, letting
the prior phase's own goal/mode/depends_on extraction bleed across the
section boundary into the next phase's body. Confirmed via a targeted
repro (**Depends on:** -- a field only the second phase has, so the
bleed is directly observable) and fixed with the same tolerance, plus
its own regression test.

CI-adjacent findings caught by gsd-test on a stale sha, fixed inline:
(1) my own explanatory comment block was inserted BETWEEN a pre-existing
`phase-id-owner:` sanction comment and the regex it sanctions, pushing
it out of the "line directly above" position lint-phase-id-drift.cjs
requires -- reordered so the sanction stays immediately above the
regex; (2) the standalone test file this fix originally added tripped
lint-test-file-count.cjs's per-module cap -- consolidated into the
existing describe block as described above.

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.

* 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.

Full suite green (796/796 across the targeted adr-612 + roadmap-parser
+ state files); node scripts/lint-phase-id-drift.cjs clean; eslint
clean on both changed files.

* 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;
eslint clean on all changed files.

* 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
scripts/lint-phase-id-drift.cjs clean; eslint clean.

* 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
scripts/lint-phase-id-drift.cjs clean; node scripts/changeset/lint.cjs
ok.

* 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

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

lint:ci` deferred to the team lead's own run per instruction.

* 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.

Targeted suite green: `node --test tests/adr-612-*.test.cjs
tests/roadmap-parser.test.cjs tests/state.test.cjs tests/verify.test.cjs`
-> 946/946 pass (942 + 4 new). Zero drift measured across the full F1-F12
corpus except F1 itself (F9/F10/F12 remain red, deferred to the
separate Major 1 fix). node scripts/lint-phase-id-drift.cjs clean;
eslint clean on both changed files.

* 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.

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

-> 952/952 pass (946 + 6 new). node scripts/lint-phase-id-drift.cjs

* 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`
-> 952/952 pass (comment-only changes, no count movement). eslint

* 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:
countRoadmapPhaseHeadings restores the bracketId guard" — RED-turned-
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).

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

* 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).

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

* 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-*,

* 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
clean.

* 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:

* 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.

Body text only; `type` and `pr` are untouched.

* 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).

929e02cb2c enhance(#3885): no silent swallow, and no verdict manufactured from dropped data (#3925)
* test(#3885): failing-first coverage for the depth bound and the manufactured wave verdict

ADR-3473 §8.5 says a swallowed failure may not become an authoritative-looking
answer. Three families do exactly that today; this commit pins each one RED.

Measured on this tree, 2026-08-27:

  intel query, .planning/intel/file-roles.json nested 12000 deep
    -> exit 1, "Error: Maximum call stack size exceeded"
       searchJsonEntries / matchesInValue carry no depth parameter at all.
       The MAX_JSON_SEARCH_DEPTH = 48 bound existed in the retired SDK lineage
       (sdk/src/query/intel.ts at 11918dcc3^) and the surviving .cts lineage
       never received it.

  same fixture nested 48 and 49 deep
    -> both return total=1 at exit 0, truncated=undefined
       Nothing distinguishes "searched to the bottom" from "stopped looking".

  query phase-plan-index, a plan whose depends_on names an unresolvable token
    -> warnings: ["Plan 03-02: declared wave: 2 but depends_on DAG places it
                  in wave 1"]
       The token is never mentioned. computeDependencyLevels drops the edge
       with `if (!resolvedDep) continue;`, every plan becomes a root, and the
       tool then reports the author's correct wave: as the thing that is wrong.

  countPhasePlansAndSummaries with fs.readdirSync throwing EACCES
    -> hasContext:false, indistinguishable from a phase that simply has no
       CONTEXT.md. context_read_error is undefined.

The shapes these tests assert against, chosen here so the implementation has a
target rather than inventing one later: `truncated: boolean` on the intel query
result, `unresolved: Array<{plan, token}>` from computeDependencyLevels, and
`context_read_error: string | null` per analyzed phase.

Deliberately green, and they must stay that way — each stops the fix from
over-firing:

  depth 48 is found and NOT flagged truncated (the ceiling is inclusive)
  a shallow miss reports no truncation           (noise control, N1)
  10,000 siblings at depth 2 are unaffected      (the bound is DEPTH, N2)
  a genuine wave: mismatch on a fully-resolved DAG still warns (N3)
  a genuinely missing directory is absent, not an error
  the emitted depends_on display mapping still passes an unresolved token
    through verbatim — already pinned by the existing #3785 test, so no
    duplicate was added

T31 asserts at the consumer's output per ADR-3180 Decision 4(b): it runs the
real CLI and reads the emitted JSON, because a unit assertion on
computeDependencyLevels would have passed throughout #3427's life.

* enhance(#3885): no silent swallow, and no verdict manufactured from dropped data

Implements ADR-3473 §8.5. A failure or a gap in the input stops being absorbed
into an output that reads as authoritative.

The recursion bound, restored but NOT verbatim (src/intel.cts)

  MAX_JSON_SEARCH_DEPTH = 48 is threaded through searchJsonEntries and
  matchesInValue, which carried no depth parameter at all. The bound existed in
  the retired SDK lineage (sdk/src/query/intel.ts at 11918dcc3^) and the
  surviving .cts lineage never received it — §8.3's "a consolidation may not
  delete an invariant along with the surface that held it", demonstrated.

  Measured before: a .planning/intel file nested 12000 deep exits 1 with
  "Error: Maximum call stack size exceeded". Reachable from a project document.

  The original returned a bare `false` at the ceiling. Restoring that verbatim
  would trade a crash for a silent "no match" when the truth is "I stopped
  looking" — the same class this epic exists to close, and ADR-3473 Decision 4
  forbids it. So the bound carries a truncation signal:

    nesting 47 -> found,     truncated false
    nesting 48 -> found,     truncated false      (the ceiling is inclusive)
    nesting 49 -> not found, truncated TRUE
    nesting 12000 -> exit 0, truncated TRUE, no RangeError

  A shallow document that simply has no match reports truncated FALSE — the
  flag means "I stopped early", never "I found nothing", or it would be noise.
  The bound is on DEPTH: 10,000 siblings at depth 2 are unaffected.

The dropped edge is named, and stops being blamed on the author (src/phase.cts)

  computeDependencyLevels dropped every unresolvable depends_on token with a
  bare `continue`. Each drop makes a plan a root, so the whole phase collapses
  to wave 1 — and cmdPhasePlanIndex then reported the author's CORRECT wave: as
  the thing that was wrong.

  Before:
    warnings: ["Plan 03-02: declared wave: 2 but depends_on DAG places it in
                wave 1"]
  After:
    warnings: ["Plan 03-02: depends_on token \"nonexistent-token-3427\" does not
                resolve to any plan in this phase — edge dropped, wave placement
                for this plan may be unreliable"]

  The suppression is PER PLAN, never blanket: a plan with a fully-resolved DAG
  and a genuinely wrong wave: still gets the mismatch warning. resolveDependencyId
  stays two-tier — the shortFormToId third tier is §8.3/Phase 6's rule and is
  deliberately not built here. The emitted depends_on display mapping still
  passes an unresolved token through verbatim (#3785).

No artifact from failed inputs (gsd-core/workflows/review.md, #3352)

  A failed lane leaves no result file, so "every lane failed" is exactly "the
  aggregate JSONL has zero lines" — the gate condition already existed as a
  byproduct. REVIEWS.md is no longer written in that case, and the commit step
  is skipped with it. A budget-SKIPPED lane also leaves no file and is NOT
  counted as a failure. Per-lane output and non-empty .err are preserved to
  .review-diagnostics/ before `rm -rf "{run_dir}"` destroys the only record that
  the lanes failed at all; the commit step names one file, never a glob, so the
  diagnostics are not swept in.

Unreadable is not absent (roadmap.cts, gap-checker.cts, init.cts x2)

  Four callers collapsed an EACCES on a phase directory into [] and reported
  hasContext:false — byte-identical to a phase that simply has no CONTEXT.md.
  Each now names the directory it could not read. A genuinely missing directory
  stays absent rather than becoming an error, which is what keeps the fix from
  over-firing.

Fatal errno folded into a retry set: audited, no defect found

  Reported as a verified negative rather than padded with a change.
  withPlanningLock was fixed by #1884/PR #3472; acquireStateLock by #3776;
  atomicRenameWithRetry and estimate-cli's renameWithRetry are correct by
  construction — bounded set {EPERM,EBUSY,EACCES}, bounded attempts, and they
  return or rethrow the final error rather than swallowing it. estimate-cli's
  sole caller surfaces that rethrow as write_error in its JSON output.
  Manufacturing a diff to make the checkbox look worked-on is the Goodhart
  outcome Decision 6 exists to prevent.

Disclosed: R46 (the commit step names one file, never a glob) is a real
regression guard but is NOT independently failing-first — the commit fence is
byte-identical pre- and post-fix, so it only fails pre-fix through its shared
extraction dependency. Recorded rather than claimed as fail-first.

* fix(#3885): escape untrusted tokens, and stop cleanup destroying unpreserved evidence

Two review findings, both real, both in my own change.

An isolated adversarial review found the evidence-preservation block never
checked mkdir/cp exit status while `rm -rf "{run_dir}"` ran unconditionally in
a SEPARATE fenced block. A disk-full or unwritable phase directory therefore
still destroyed the only copy of the failed lanes' output — reintroducing the
exact #3352 data loss this item exists to stop, inside the fix for it.

Preservation and cleanup are now one block, because each fenced block is a
separate execution and a shell variable cannot carry between them. mkdir -p and
each cp are exit-checked; cleanup runs only when preservation succeeded, and a
failure warns naming the intact run directory. "Nothing to preserve" is not a
failure and still cleans up. Driven three ways: success removes run_dir, failure
leaves it intact with the warning, nothing-to-preserve removes it. The failure is
induced by a file-vs-directory conflict rather than chmod 0o000, which root
bypasses.

The new unresolved-depends_on warning embedded a user-authored token verbatim:

  warnings: ["Plan 03-02: depends_on token \"evil
  Plan 03-01: FORGED WARNING\" does not resolve ..."]

The JSON wire form is safe, and the security reviewer judged it non-exploitable
for that reason. It is escaped anyway through formatDiagnosticToken — the helper
#3884 added one phase earlier for exactly this class. warnings[] is an array a
consumer naturally prints line by line, and not reusing the sibling fix is the
generative-fix-divergence shape this epic exists to close. The same treatment is
applied to context_read_error / phase_dir_read_error, which embed a phase
directory path a repository can choose, and to the fs error message, which
echoes the raw path itself.

Known limit L5 recorded: the bound is on DEPTH only. A 300,000-element shallow
array yields a 14.5MB reply with truncated:false. Correct per §8.5 and per
negative space N2, disclosed rather than left to be discovered.

* fix(#3885): unreadable is not absent in intel.cts either, and a corrupt snapshot is not "no snapshot"

Blocker from the round-2 isolated review, and it is my own inconsistency:
this phase applied "unreadable is not absent" to phase directories and left it
broken in the file it was already editing.

  chmod 000 .planning/intel/file-roles.json
  gsd-tools intel query <term>
  -> {"matches":[],"total":0,"truncated":false}  exit 0

safeReadJson swallowed every read failure and returned null, so an EACCES was
byte-indistinguishable from an absent file AND from a genuine no-match. Now it
separates three states: ENOENT stays silently absent, because not every project
has every intel file and intelQuery loops over all of them expecting misses;
EACCES/EIO and malformed JSON are both surfaced naming the file. A corrupt intel
file previously read as "no matches" too — same defect, same fix.

Threading that outcome through the other three callers found something worse
than the reported case. intelDiff returned no_baseline:true for a corrupt or
unreadable snapshot — not a silent failure but an actively FALSE verdict, telling
the caller they never took a snapshot when they did. That is §8.5's headline
case, so it is fixed and tested rather than noted. intelStatus and
intelApiSurface collapsed the same way; intelApiSurface additionally printed a
"not yet populated" banner that was simply untrue.

Every row is failing-first, including the absent-file ones — the field is new,
so it does not exist pre-fix at all. Those rows are not pre-fix pins; they pin
that the fix does not OVER-fire on the ordinary absent case, which is what would
turn this into noise on every project lacking an intel file. IO failure is
injected by monkeypatching fs and restoring in finally, never chmod 0o000 — root
bypasses mode bits, so the reviewer's manual chmod repro is not reproducible as
a test.

* test(#3885): build the pathological intel fixture as text, not by stringifying a nested object

The remote runner came back red on Linux with two failures, both
T4: deeplyNestedIntelDoesNotOverflowTheStack, while the same test passed on
macOS. The product was never at fault.

writeNestedFixture(12000) built a 12,000-deep JavaScript OBJECT and then
JSON.stringify'd it. JSON.stringify recurses once per level, so it overflowed
the TEST PROCESS's stack — the error was thrown before the CLI was ever spawned.
Linux's container stack is smaller than macOS's, which is the whole of the
platform difference.

Measured, with the same document built as JSON TEXT so nothing in the building
process recurses:

  depth=100    rc=0 truncated=true
  depth=5000   rc=0 truncated=true
  depth=12000  rc=0 truncated=true
  depth=60000  rc=0 truncated=true

V8 parses this shape iteratively; only stringify recurses. The bound works at
every depth tried.

The fixture is now built by string concatenation. That is also the more faithful
input — a real deeply nested JSON document on disk is exactly what the bound
guards, where a stringified object was only ever a way to produce one.

The depth stays 12000. Lowering it would have made the test pass by weakening it
to accommodate a fixture bug, and 12000 is a legitimate pathological input the
product handles. T4 remains a genuine fail-first: rebuilt against the parent of
the commit that added the bound, the string-built depth-12000 fixture still
drives the CLI to rc=1 with "Error: Maximum call stack size exceeded".

A comment records why the fixture is text, so it is not "simplified" back into a
macOS-green / Linux-red test.

* test(#3885): normalize path separators before splicing into the workflow's bash

CI red on one lane — test (windows-latest, 24, shard 3/3). macOS, Linux and the
remote runner were all green.

  AssertionError: commit must name the single REVIEWS.md file; got:
    --files C:UsersRUNNER~1AppDataLocalTempgsd-3352-phasedir-mOKmuy/03-REVIEWS.md

Every backslash in C:\Users\RUNNER~1\AppData\Local\Temp\... was eaten. The
harness spliced an OS-native temp path into the extracted bash, and bash consumes
\U, \A, \L and \T as escapes on an unquoted expansion. The same loss broke
RUN_DIR, so "rm -rf" targeted a path that never existed and the run directory
survived — which is the other two assertions.

This is a fixture defect, not a product one, and that was checked rather than
assumed. In production the phase directory is toPosixPath-normalized at every
call site that serializes it (bin/lib/init.cjs:951, 1381, 1461, 1529, 1595), and
the run directory is created by "mktemp -d" running inside the bash block itself
(gsd-core/workflows/review.md:163), which emits POSIX-style output even under
Git-Bash on Windows. Neither ever carries a backslash where the workflow reads it.

The file's pre-existing #3034 harness splices raw native paths too, but only ever
inside double-quoted assignments, so it never tripped this — my new harness
followed that convention faithfully into the one place where it does not hold.
Both now splice through toPosixPath from shell-command-projection, the
established seam, which is a no-op on POSIX and mirrors what production does.

No assertion was weakened. "commit must name the single REVIEWS.md file" and
"the run dir must still be destroyed" still assert exactly that; only how the
fixture supplies its path changed. Nothing is skipped on Windows — a t.skip()
here would have hidden the question of whether the exposure was real, which is
the question that mattered.

Driven both ways: a synthetic C:\Users\RUNNER~1\... input reproduces the exact CI
string when unfixed and yields C:/Users/RUNNER~1/... when fixed; a POSIX input
produces a byte-identical shape, proving the normalization is idempotent.

* test(#3885): stop the harness making the deleted run dir its own cwd

Windows shard 3/3 stayed red after the separator fix, on two assertions the
separator fix never touched:

  AssertionError: the run dir must still be destroyed
  AssertionError: nothing to preserve is not a failure — run dir must still be removed

The separators were a real bug and fixing them fixed the --files assertion. They
were not this bug, and two CI cycles went into the wrong axis before I stopped
converting path forms and looked at what the harness actually does.

runWriteReviewsFlow passed cwd: runDir to runHook, so the child bash process's
working directory WAS the directory the block under test then removes with
rm -rf "$RUN_DIR". POSIX allows a process to delete its own cwd — verified
locally, cd "$d"; rm -rf "$d" removes it cleanly — and Windows does not: a live
process's working directory cannot be removed. So on Windows the directory
survived and both assertions failed, on macOS and Linux it vanished and they
passed. Nothing to do with slashes.

Harness-only. Production never cd's into the run directory; every reference is by
absolute path, and RUN_DIR is created by mktemp -d inside the bash block itself
(gsd-core/workflows/review.md:165) rather than injected. review.md is unchanged.

Fix: the child now runs with its cwd in an unrelated temp directory that the
block under test never deletes. Neither assertion was weakened, and nothing is
skipped on Windows — the tests in this file carry no platform guard and run
there unconditionally, which is how this surfaced at all.

Honest limit: the Windows failure mode cannot be reproduced on macOS, because
POSIX permits the very thing Windows refuses. The diagnosis is grounded in that
documented divergence and in the fact that only the Windows lane failed, but the
green outcome on windows-latest is unverified until CI runs it.

a638ca4332 enhance(#3882): stop sentinel phases skewing estimation calibration (#3893)
* test(#3882): failing-first rows for sentinel phases skewing calibration

Adds A1a/A1b/A2/A3 to tests/estimate-calibrate.test.cjs, the module's
existing test file, rather than a new bug-NNNN file. collectCalibrationSamples
(src/estimate-cli.cts:206) does a raw readdirSync over .planning/phases and
never applies isSentinelPhaseId, so a sentinel phase (milestone 0 or 999)
carrying a PLAN estimate / SUMMARY actuals pair contributes a phantom
calibration sample.

computeCalibration is median-based, so a single 50x outlier among three
samples leaves the factor unmoved — asserting "the factor is unchanged"
against one sentinel would pass on the broken code for the wrong reason.
Each row instead asserts the WHOLE computed CalibrationResult object
(factor, applied, confidence, sampleCount, clamped) for a sentinel-free
project against its sentinel-injected twin:

- A1a: one sentinel flips applied false->true and confidence low->med on
  phantom evidence (calibration switches on with zero real signal).
- A1b: two sentinels corrupt the factor itself (1 -> 3, clamped false->true).
- A2: the sentinel's own sample is verified absent from the returned list.
- A3: the two genuine phases still contribute their own unchanged samples
  (regression pin — stops A1/A2 passing by filtering everything).

Verified RED on today's code (node tests/estimate-calibrate.test.cjs):
A1a/A1b/A2 fail with the exact differing objects; A3 and all pre-existing
rows in the file remain green (no collateral).

* feat(#3882): route phase enumeration through its owner and name the sentinel axis

Task 1: collectCalibrationSamples (src/estimate-cli.cts) hand-rolled a raw readdirSync over .planning/phases, treating every directory (including sentinel phases, milestone 0/999) as a completed phase and feeding phantom PLAN/SUMMARY samples into the estimation calibration factor. Routed through the existing owner, listMilestonePhaseDirs(phasesRoot) with no cwd -- already 'all milestones, sentinels excluded', exactly the combination this caller needs; no new API was required for this half. It now also surfaces the scope discriminator: an unreadable phases directory throws PhasesUnreadableError instead of silently returning zero samples, and cmdEstimateCalibrate reports it via a new ERROR_REASON.ESTIMATE_PHASES_UNREADABLE instead of persisting a phantom empty calibration document.

Task 2: added listAllPhaseDirs(phasesDir, { includeSentinels }) to src/phase-locator.cts -- the one genuinely missing axis: 'physical set, sentinels INCLUDED'. includeSentinels has no default and is required, so a call site cannot obtain sentinel-inclusion by omission (compile-time refusal, not just documentation). Mirrors listMilestonePhaseDirs's absent/unreadable scope handling.

Task 3: migrated the two exemptions whose written reason maps cleanly onto 'physical set, sentinels included' -- cmdRoadmapAnalyze's _phaseDirNames (src/roadmap.cts) and cmdInitMilestoneOp's diskPhaseDirs (src/init.cts), both heading->directory lookup indexes. Left the rest: archivePhaseDirectories's own body has no readdirSync to migrate (its callers already resolve dirs before calling it, and both current callers deliberately EXCLUDE sentinels -- migrating it would be an unauthorized behavior change, not an API swap); cmdValidateHealth's exemption is vestigial (its actual physical-set sweep already lives in planning-snapshot.cts's buildAllPhaseDirNamesField, a pre-existing near-duplicate of the new axis, flagged as a finding, not restructured); cmdPhasesClear/cmdMilestoneComplete/cmdVerifySchemaDrift/detectHasPriorPhases/detectUiPhaseActive want a different combination (sentinels excluded, or a single-phase lookup) and are unaffected.

Task 4: detector 2 (sentinel literal) is untouched and retained. Removed exemption entries only for the two migrated call sites; every other function-scoped exemption is preserved. Guard exits 0.

* refactor(#3882): delegate the snapshot phase-dir scan to its owner

buildAllPhaseDirNamesField duplicated listAllPhaseDirs's own
readdirSync + directory-filter + absent/unreadable handling — the
'one implementation per rule' defect ADR-3473 SS8.3 names, introduced
by this branch's own #3882 work. Delegate to listAllPhaseDirs and
re-apply the field's existing lexicographic sort on top, since W007's
observable order must not change.

* docs(#3882): document the sentinel axis and the enumeration consolidation

Records listAllPhaseDirs in the Phase Locator glossary entry, and the fact
that the owner already answers the all-milestones sentinel-free question when
called without a cwd -- the call collectCalibrationSamples was missing.

Also notes that buildAllPhaseDirNamesField now delegates rather than carrying a
second readdir, and that exactly one readdirSync over the phases directory
remains across the two modules.

0f417aa6d0 fix(#3584): the verb owns the count token and nothing else (#3635)
* test(3584): failing-first coverage for Plans-line trailing text

roadmap update-plan-progress preserves trailing text only when the line begins with a
canonical count token. Every other phrasing — including the TBD value the shipped
template itself suggests — is replaced to end-of-line, and a sentence wrapping onto a
second line has its first line deleted, leaving the continuation standing alone so the
roadmap asserts something nobody wrote. Exit 0, updated:true, and the diff reads as a
routine count bump.

These tests fail on that, and pin the arms that must keep working: the template
placeholder is still replaced, the #2853 token-plus-annotation path is unchanged, CRLF is
neither stranded nor duplicated, and a run that leaves the line alone still updates the
Progress table and checkboxes rather than becoming a no-op.

* fix(3584): the verb owns the count token and nothing else

RED proven at 105bdf7c: 7 failures — the preserving cases (freeform prose, wrapped
continuation, TBD, CRLF) failed while the template-placeholder and #2853 token arms
passed on base.

The trailing-text guard fired only when the line began with a canonical count token:
 dropped the rest of the line whenever the
regex's count group did not match. #2853 fixed end-of-line truncation on that one path
only. The in-code comment justified the rest as 'the fresh-template bracketed placeholder
or other freeform guidance, not user prose' — a heuristic that misreads ordinary human
phrasing and destroys even TBD, the value the shipped template itself suggests at
templates/roadmap.md:37.

The sharper failure was the wrapped sentence: only the first line is inside the match, so
the verb deleted line one and left line two standing alone, leaving the roadmap asserting
something nobody wrote — at exit 0, updated:true, in a diff that reads as a routine count
bump.

Inverted the default into three arms. A real count token is rewritten with its annotation
preserved (unchanged, #2853). A bracketed placeholder is detected POSITIVELY and replaced.
Everything else — freeform prose, TBD, a wrapped sentence's first line, an empty value —
returns the match untouched. That last arm resolves the wrapped case by construction: an
untouched first line cannot orphan its continuation.

Positive detection is the load-bearing part. Implemented as 'not a count token, therefore
disposable', rows 1-3 come straight back; the detector instead asks whether the value IS a
bracketed placeholder.

Leaving the line alone does not make the verb a no-op: the phase checkbox, the
Progress-table cells and the plan-checklist row still update in the same run, and that is
asserted. CRLF is unaffected in every arm — the pattern's [^\r\n]* never consumes the
\r, so it sits outside the match regardless of which arm runs.

Fixes #3584

* fix(3584): detect the template placeholder by its text, not by its brackets

Two defects in the arm-2 detector shipped in fc23e49e, both found in review.

Finding A: isBracketedPlaceholder asked only whether the trimmed value was wrapped
in [...]. Brackets are ordinary prose punctuation in a roadmap, so any hand-written
bracketed note — '[Deferred pending re-scope]', '[blocked on #1234]' — was classified
as the fresh-template placeholder and destroyed. That is the very defect #3584 is
about, reintroduced one arm over. The detector now matches the placeholder's TEXT
(/^\[\s*Number of plans\b[\s\S]*\]$/i), so it recognizes the shipped template
value and its short form and nothing else.

Finding B: the count group matched '\\d+\\s+plans' only. The plural is not the
template's own output shape — templates/roadmap.md:62 ships '1 plan' — so a
single-plan phase fell through every arm and its line froze permanently, never
updating again. Widened to 'plans?'. This one was introduced by the arm-3 default:
before it, the singular fell through to the old replace-everything path and at
least stayed current.

Cases 11-14 cover both: a bracketed human note preserved, the short placeholder
still replaced, '1 plan' rewritten, and '1 plan (annotation)' rewritten with the
annotation intact. Verified against the live binary, not just re-read.

Also converted all 15 cases in this block from try/finally to t.after(), per
CONTRIBUTING.md:356-370 which bans try/finally in test bodies. The existing #2853
block above is untouched — it is not in this change's scope and its conversion is
not this fix's concern.

dfc4c69e3d fix(#3577): recognize markdown-table phase rows across the roadmap enumeration family (#3599)
* test(#3577): pin table-declared phase resolution across all four surfaces

Failing-first regression for #3577: a GFM table phase listing (Phase header,
id in the first data cell) declared real phases that roadmap.analyze,
roadmap.get-phase, init.phase-op, and the milestone filter all reported as
absent (phase_count: 0 / found: false). Rows pin the lookup, the scope
probe, the analyzer, schema discrimination against the canonical
RoadmapProgress table, fenced-example exclusion, heading+table union
without double-count, decimal ids, and the 999 icebox exclusion.

* fix(#3577): recognize markdown-table phase rows across the enumeration family

A GFM table whose header leads with Phase and whose data rows carry the id
in the first cell is a phase listing — the #2199 bullet blind spot's table
sibling. collectTablePhaseRows (schema-discriminated against the canonical
RoadmapProgress table via matchTableSchema, fence-aware via stripFencedCode,
digit-bearing id shape, 999 icebox excluded) now feeds: the milestone
filter's sole owner scanMilestonePhaseIds, window classification
hasPhaseEntries, both roadmap lookup chains (getRoadmapPhaseInternal +
cmdRoadmapGetPhase, as last-resort tiers after heading and bullet), and
roadmap analyze's enumerator (with the same disk enrichment contract as
headings and a zero-pad-tolerant duplicate guard). init.phase-op resolves
through its existing getRoadmapPhaseInternal fallback.

* fix(#3577): GFM table termination + icebox word boundary in the table scan

Review findings: the row harvest broke only on blank lines, so prose after
a table (a bare date line) could be harvested as a phase id — rows now stop
at the first non-row line per GFM semantics; the 999 icebox exclusion gains
the heading scan's word boundary so 9991 is kept.

* fix(#3577): sanction collectTablePhaseRows in the enumeration drift scanner

The scan's local 999-only exclusion mirrors its parent owner
scanMilestonePhaseIds' deliberate NOT-isSentinelPhaseId choice (a leading 0
is a real decimal phase, #2554), so it cannot route through the sentinel
owner — function-scoped exemption with the documented reason, same entry
shape as the #3262 owner's.

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).

  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

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

* 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.

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

* 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.

aceea3ce4a refactor(#3217): withhold a percentage when its scope is not complete (#3318)
* wip(#3217): rule-4 scope withholding — parked, two open findings

Implemented but NOT shippable. An isolated review found buildStateFrontmatter
still hardcodes SCOPE.COMPLETE, so state json reports percent 0 where roadmap
analyze, stats and query progress all correctly report null on the same disk
state - rule 4 reintroduced at a site this phase claims to close. Also: roadmap
analyze emits scope complete beside progress_percent null with nothing
explaining it.

Parked to build Phase 4 (#3186) first, which is unblocked. Findings recorded in
.gsd/phase/refactor-3217-completion-ratio-scoping/60-review.json.

* fix(#3217): withhold the sync percentage on a non-complete scope

The parked blocker is fixed - buildStateFrontmatter no longer hardcodes
SCOPE.COMPLETE, and the prose Progress fallback is gated too, which was a second
leak found while tracing the first. roadmap analyze exposes progress_scope so a
consumer can tell WHY a percentage is absent from the JSON alone.

Then a residual gap was reproduced rather than assumed. cmdStateSync carried the
same hardcode behind a written reason claiming it did not reproduce. It did: on a
TRUNCATED window and on UNSCOPED row 4, state sync wrote Progress 0 percent to 100
percent while state json, roadmap analyze, stats and query progress all withheld -
and it persisted a self-contradictory file, body claiming 100 percent while its own
frontmatter correctly omitted percent.

The excuse was also wrong. syncRoadmapRaw is already parsed in that function and is
exactly what produces a real scope, so there was a scope to pass. Threaded through
listMilestonePhaseDirs; a non-complete scope now skips the write with a reason in
changes. milestoneBounded stays as the orthogonal 1761 guard for row 5.

Second time this epic a does-not-reproduce claim was too generous. Recorded in
ADR Amendment 8 as a correction rather than a quiet rewrite.

Verified on the remote runner.

* test(#3217): give the withholding fixtures a resolvable scope

40 matrix failures, all fixture drift - no code regression. My own hypothesis
that this was over-withholding was wrong and is recorded as such: the worry case,
a plain ROADMAP with Phase entries and no version heading, resolves to complete
exactly as ADR 7.1 says it should.

The real causes were two fixture shapes. Most had no ROADMAP.md at all, which is
unreadable via a pre-existing graceful path, and asserted a numeric percent. The
five vscode, pi-extension, mcp-server and shell-projection failures were that
shape - bare temp dirs using progress json as a reachability proxy while
asserting typeof percent is number, which under rule 4 is now null.

The rest had a version token in a title or heading with no STATE.md milestone
pointer to resolve it, which is classification row 4, versioned but unresolved,
so withholding is correct per the contract.

Verified on the remote runner.

* test(#3217): make the LM-tools reachability tests dispatch against their fixture

The gsd_progress reachability test was never testing its fixture. invoke()
resolves cwd from vscode.workspace.workspaceFolders by design (the real
LanguageModelToolInvocationOptions has no cwd field, per the 2103 fix in
extension.js), the mock had no workspace at all, and the test passed a cwd option
nothing reads - so it dispatched against the repo working directory. Writing a
ROADMAP into the temp dir had no effect. Rule 4 only made it visible.

Fixed by mocking workspaceFolders. The two siblings in the same file carried the
identical dead cwd and were dispatching against the repo too; they were not
failing only because their assertions did not touch scope-dependent output. Both
now use their own fixture with assertions unchanged - the no-planning fallback
paths already satisfy them honestly.

Re-scanned the other five reachability files: no further instances. They thread
cwd into parameters that genuinely read it, not through an options shape that
ignores it.

Verified on the remote runner.

* chore(#3217): backfill changeset PR number

pr:0 placeholder replaced with the real number now that #3318 exists.

* ci(#3217): give the coverage merge enough heap for the merged shards

The coverage gate OOMed at exit 134. c8 report merges three shard artifacts,
roughly 358MB of V8 dumps in coverage/tmp, and died holding their per-file
position maps at the ~4GB default heap. Verified as this branch's delta rather
than pre-existing: the same job succeeded on next at 14:18, after phases 4 and 5
merged.

Both coverage-gate steps get the bump because both re-slice the same merged data.
8192 doubles what failed and leaves headroom on a 16GB ubuntu runner, matching
the idiom the shard step already uses at 6144.

This is a memory bound, not a change to what is measured. No threshold was
touched. The test file was checked for gratuitous subprocess spawning and is
already reasonable at 43 spawns, each a distinct fixture-by-surface pairing.

Verified on the remote runner.

e201cde73c refactor(#3186): one shared phase-completion predicate, disk-strict (#3306)
* docs(#3186): record the disk-strict completion decision in ADR-3180 7.4

The maintainer decided #2957 on 2026-08-08: disk state is authoritative and a
ROADMAP checkbox is a human annotation with no machine authority. Section 7.4
still carried the OPEN QUESTION and was marked blocked, so the contract said one
thing and the tracker another.

Recorded per section 7's own rule - a behavior not stated there is not decided,
and amending a rule is an ADR amendment rather than a code change with a comment.
The decision comment names Phase 4's PR as the carrier of this edit and makes it
an acceptance criterion that the text be in the tree before implementation
begins, so this lands first, alone, ahead of any code.

Also clears the stale blocked-on-2957 row in the guard roster.

* refactor(#3186): one shared phase-completion predicate, disk-strict

isPhaseComplete in verification.cts becomes the single owner. It calls
readVerificationStatus UNCONDITIONALLY - plan count is not a precondition - so a
zero-plan phase with a passing VERIFICATION.md is complete. That is #3168: init
gated the read on a plan count and synthesized a not_required sentinel, so
phase.complete succeeded while init.manager reported incomplete for the same
phase.

The guard, built and run before scope was fixed per Amendment 3, found 9
re-derivations where the ADR named 3. Four were unnamed, including one in the
prompt layer: mvp-phase.md ORed a ticked checkbox with disk status, which under
disk-strict is the divergence itself.

Per the #2957 decision, a ticked ROADMAP checkbox is a human annotation with no
machine authority. The overrides in roadmap analyze and init manager are deleted
rather than generalized; the user's checkbox stays in ROADMAP.md, only its
authority goes.

scanPhasePlans.completed and buildWorkstreamInventory are deliberately NOT folded
- they answer 'are all plans summarized', which is a different question, and
folding them would either over-report completion or invert the dependency
direction between Phase 1's owner and this one.

Verified on the remote runner.

* fix(#3186): close seven review findings and record the missing-verdict rule

The isolated review reproduced a write-path regression I introduced: migrating
cmdRoadmapUpdatePlanProgress dropped its summaryCount>=planCount gate, so a phase
with a fresh passing verification plus a newly-added unsummarized plan reported
complete AND wrote a checkbox into ROADMAP.md while phase complete refused. The
owner stays right per 7.4 - plan count is not a completion precondition - so the
gate is restored at the write site as an explicit composition, mirroring the
separate 2648 unexecuted-plan gate cmdPhaseComplete already carries.

The spec axis was right that my 0.x-split reasoning was too permissive. The 2957
decision names buildStateFrontmatter as one of the three that must converge, and
buildWorkstreamInventory combined a summaries-met local with verification data to
decide the same verdict - Decision 4(c)'s named bypass, and it reproduced 3168 in
a third surface. Both now route through the owner. The raw scanPhasePlans helper
stays: it answers are-plans-summarized, which genuinely is a different question.

Maintainer decision recorded in 7.4: a missing verdict is not a passing one, so
an absent VERIFICATION.md means not complete everywhere. That retires 2645's
verifier-disabled tolerance and inverts its Goodhart incentive - deleting the
evidence now lowers completion instead of raising it.

Guard hardened: block-form count gates and algebraic restatements are caught, and
the header now discloses its remaining limits instead of overclaiming.

Verified on the remote runner.

* fix(#3186): route state sync through the owner and catch bare completed reads

The matrix found 52 failures. 51 were fixtures asserting the old semantics: a
phase with plans and summaries but no VERIFICATION.md used to count complete and
correctly no longer does. Each fixture now carries a passing verification where
that is what the test was actually about, rather than having its assertion
weakened.

The 52nd was a real 10th re-derivation the guard could not see. cmdStateSync
destructured scanPhasePlans().completed directly - a bare field read, not a
comparison - and used it as a completion verdict, so state sync and state json
disagreed on completed_phases for identical disk state. Routed through the owner.

Guard gains shape (d): any read of .completed off a scanPhasePlans() result
outside plan-scan.cts, in chained, destructured and indirect forms, function
scoped with no line window. It cannot tell a summaries-met read from a completion
read - that is data flow - so it flags every one and requires a written-reason
exemption, which is the same discipline shapes a-c already use. The blind spot is
disclosed in the header rather than overclaimed.

The emitted-attribution failure was also mine, not pre-existing: the mvp-phase.md
checkbox-OR removal moves emitted bytes, acknowledged in tests/emitted-drift-acks.

Verified on the remote runner.

* test(#3186): give the nested-plans sync fixture a passing verification

Last 3 matrix failures were one failure echoing up two describe levels. Phase
01-alpha had plans and summaries but no VERIFICATION.md, so under disk-strict
completed stayed 0 and no Progress change was emitted - correct new behavior, not
a regression.

Added the passing verification rather than dropping the Progress expectation, so
the test still covers what #3257 is about: that a nested plans/ layout is counted
and not undercounted. Probe against the built lib confirms
Progress: 0% -> 50% alongside Total Plans in Phase: 0 -> 3.

* chore(#3186): backfill changeset PR number

pr:0 placeholder replaced with the real number now that #3306 exists.

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.

b9f51836e6 refactor(#3180): ADR-3180 behavior contract + cross-surface drift guardrails (#3223)
* refactor(#3180): one owner for completion ratio, a prompt-layer drift guard, and a written behavior contract

The 2026-08-08 coverage audit on #3180 found the epic's copy counts were a
lower bound for the third consecutive time, and that two derivation families
had never been named at all.

ADR-3180 gains Decision 7 — a normative behavior contract that says what the
right answer IS for each derivation, not merely who owns it. A reviewer with
no written rule can only ask "does this look like the others", which is how a
fifth copy passes review. Decision 4 gains (d) scan surface is every authored
surface and an owner FILE is never exempt, only its named functions; and (e)
a surface that cannot be consolidated today ships ratcheted, never unguarded.

Completion ratio: `clampPercent` sat exported and unused beside six hand-inlined
copies of its own body across five modules. All six now route through it;
`clampPercentFromFraction` is added for the one caller that already held a
fraction. Every migration is behaviour-identical — clampPercent's first line IS
the `total > 0 ? … : 0` ternary each copy carried. Guarded by
lint-completion-ratio-drift.cjs, which reports zero re-derivations with no
file-level exemption.

Prompt layer: workflow markdown re-derives live-plan counting in raw shell
(#1762), invisible to every `src/`-scoped guard. lint-planning-prompt-drift.cjs
scans it with a shrink-only baseline of the 7 sites that exist today — new
sites fail, and a baseline entry that stops firing fails too, so an
acknowledgment can never outlive the thing it describes.

lint-milestone-window-drift.cjs stops exempting its owner file wholesale; only
the four named canonical functions are exempt now. The blanket exemption was
pointed at the one file most likely to grow the next copy, and it had.

* fix(#3180): address orthogonal review — consumer-output identity tests, count-keyed ratchet, property coverage

Five findings from the two orthogonal review passes, all fixed.

Decision 4(c) breach: the completion-ratio identity test asserted at the
OWNER, which is exactly the bypass that decision exists to close — a consumer
can call clampPercent and then post-process locally, leaving both the lint and
an owner-level test green. It now drives `roadmap analyze`, `query progress`
and `stats` and asserts on their own output, over a fixture containing a
`status: superseded` plan so a consumer that re-counted raw files would report
60 where the owner reports 75.

Decision 4(e) breach: ratchet entries named the epic (#3180) rather than the
issue that removes them. They name Phase 8 (#3218) now.

The ratchet keyed on (file, text) alone, so plan-phase.md's two byte-identical
sites were one indistinguishable key and migrating either would have left the
guard green with the other alive. Entries carry an occurrence count; fewer than
acknowledged fails as a partial migration, more fails as a new copy.

Adds the missing MAX_REGEX_LITERAL_LEN boundary coverage the sibling guard's
test already had, and the fast-check property tests CONTRIBUTING requires for
clamp/budget-limit functions.

* test: stop wrapping a nested double-spawn in a 15s wall-clock budget (bug #641 probes)

`tests/ci-test-scope.test.cjs`'s `bug #641` block spawned `run-tests.cjs`
under PROBE_TIMEOUT_MS=15000; that child then spawned a nested `node --test`.
A fixed wall-clock budget around a double spawn, running inside a container
that is concurrently executing the full ~31k-test suite, fails by construction
under load.

Confirmed against three full matrix runs. Every failure was shaped
`null !== 0` — the child was KILLED, never an assertion about the thing under
test. One captured probe had already printed the correct resolution
(`suite="all" files=2: a.test.cjs b.test.cjs`) and was killed anyway. It
reproduces on `next` alone: 5 failures on linux-node22, 0 on linux-node24. The
victim subset varies by run and by lane.

What these tests are actually about is suite-token RESOLUTION — `unit` as a
bare token in --files/--files-from. Executing the seeded trivial files is
incidental and is the entire timeout surface, so the assertions move
in-process against the same functions `main()` calls, in the same order.
`parseArgs`, `selectExplicitFiles`, `selectFiles` and `walkTestFiles` are
exported for that; no behavior, signature or logic changed.

No coverage lost: `tests/run-tests-harness.test.cjs` already spawns the
harness for real and asserts exit codes end to end, on a 120s budget.

Pre-existing on `next`, fixed here rather than deferred.

* test: delete the three elapsed-time assertions

CLAUDE.md forbids asserting on wall-clock time. Three assertions did, and all
three are load-sensitive: on a saturated bench each can fail while the code
under test is correct. In every case the load-bearing assertion sits on the
line above and the timing line adds no discrimination.

run-with-timeout: the stated worry — "was this 124 the cap firing or the 30s
harness backstop?" — is already answered by the assertion above it. A backstop
kills by signal, which surfaces as status null, never 124. Observed directly
this session: three matrix runs produced exactly that null shape from killed
children.

normalize-test-command and context-predicates: both bounded a ReDoS check.
A threshold only ever separates "fast" from "slightly slow", which is bench
load, not correctness — catastrophic backtracking on 800 KB of input does not
take 251ms, it does not finish at all. A real regression therefore shows up as
the suite being killed on that test, which is louder and more reliable than a
number. The structural assertions (returned unchanged; cleanly rejected) are
what actually carry those tests, and they stay.

The sweep now reports zero elapsed-time assertions in tests/. The remaining
Date.now() uses are unique-path suffixes, barrier deadlines, fixture
timestamps and fake mtimes — none of them assertions.

Pre-existing on `next`, fixed here rather than deferred.

* fix(#3180): key the prompt-drift ratchet on POSIX paths so it works on Windows

The baseline keys on (file, trimmed text). `file` came from scanTree's
`path.relative()`, which uses NATIVE separators, while the committed baseline
stores POSIX. On Windows every violation was therefore unmatched — reported as
FRESH — and every baseline entry matched nothing — reported as STALE. The guard
failed 100% of the time there, on both CI shards:

  ✖ scanRepo(repoRoot) matches the baseline exactly: zero fresh AND zero stale
    + { file: 'gsd-core\\workflows\\execute-plan.md', ... }

The remote runner this repo gates on is Linux-only and cannot see this class at
all; the GitHub Actions Windows lane is what caught it.

Normalization is unconditional — never gated on process.platform. A
platform-conditional normalizer makes the POSIX path the special case and
leaves the Windows branch unexercised on every other OS, which is the same
blind spot in a different place. It is applied at one seam inside
findPromptDrift, which builds `file` on every returned violation, so the
baseline key, the --update writer, the stderr report and the tests all consume
one normalized value.

The regression tests drive a Windows-shaped relPath directly and run on every
OS rather than skipping off-Windows — a test that only runs on the platform
where the bug lives is why this escaped. They include a sanity check that
un-normalized input does NOT match, so the assertion cannot pass vacuously.

Audited the three sibling guards: none keys against a committed cross-platform
baseline, and their exemption keys are path.join-built, so producer and
consumer share the native convention. Left correct code alone rather than
making them look alike. scripts/lib/drift-scan.cjs is untouched — normalizing
there would break those three on Windows.

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.

Amendment 3 records: the SCOPE contract held unchanged; the declared deviation
from Decision 1's provisional signature (the window needs cwd/ws, which the
locked roadmapContent parameter cannot supply); the copy count being a lower
bound for the third consecutive phase (4 scoped vs 54 found); the load-bearing
finding that the sentinel exclusion sat on the heading set and was unreachable
under the pass-all degrade; the two destructive-path defects; and the
generalized exemption rule.

* 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.

roadmap.analyze's phase-heading discovery and checklist discovery regexes

53ea8e0664 fix(#3057): make a guard's failure distinguishable from its benign result — Wave 1 (#3088)
* fix(#3057): refuse the write when the duplicate scan cannot complete

writeManifest documents itself as a fail-closed duplicate guard: if any
existing manifest shares plan_id with a different, non-terminal job_id it must
refuse, because dispatching again would duplicate the external job.

It could not honour that. The scan reads every sibling manifest looking for the
duplicate, and an unreadable or unparseable sibling was `continue`d past. If
the corrupt file was the one holding the live duplicate, the scan found nothing
and a duplicate external job dispatched.

The asymmetry is what gives it away: a malformed TARGET refused with
malformed_existing because clobbering is unacceptable, while a malformed
SIBLING was skipped — yet siblings are the only thing the duplicate check
reads.

Adds a scan_incomplete verdict that refuses and names the offending file, so an
operator can quarantine or repair it. Fail-closed alone would let one stale
corrupt manifest wedge every dispatch for that planning dir permanently; naming
the file is what makes refusing survivable. malformed_existing is untouched, so
the target/sibling distinction stays visible. The docstring is updated — it
previously stated a rule the function did not keep.

memFs() gains an optional failReads map so these branches are reachable at all;
they had zero coverage because the fake could not express a per-file read
fault. The signature is additive and every existing caller is unchanged.

The regression is proved by a pair, not a single test. A control writes a
readable sibling holding a genuine non-terminal duplicate and asserts
duplicate_plan_id, establishing the scenario is real; the regression then makes
that same path unreadable and asserts scan_incomplete. A first draft of this
test used a corrupt-JSON fixture containing no plan_id at all while its comment
claimed otherwise — it duplicated the unparseable-sibling case and proved
nothing, which is the defect class this phase exists to remove.

* fix(#3057): make a guard's failure distinguishable from its benign result

Wave 1 of the negative-space backfill: the branches where a guard that could
not verify something reported the same value it reports when everything is
fine. That indistinguishability is the defect; every fix here makes the two
states tellable apart, and every test proves it with a pair — one for the
failure, one for the benign case. A single test cannot establish that two
states are distinguishable, which is the whole property being fixed.

state.cts phaseInventoryProvider returned null for both a real disk-scan
failure and a genuinely empty phases dir, so `state rebuild` could report
success while phase-table reconciliation never ran. It now returns a
discriminated result and the CLI surfaces phase_inventory_scan_failed plus a
reason. The reason field turned out never to have been wired into the emitted
JSON at all — it existed only as an internal variable — so a test could only
assert on the operator-facing note. It is a real field now.

state.cts treated an unreadable lock body the same as an empty one, applying
the 1-second stealable floor. A lock we cannot read is not a lock we know is
stale; an unreadable body is now held to the deadman ceiling like a live
holder.

verification.cts findStaleVerificationSummary returned null on any fs, scan or
clock failure — meaning "not stale". It now returns a discriminated
StaleCheckResult and the caller records that the check was indeterminate.

git-base-branch resolveBaseBranch returned 'main' both when no candidate branch
existed and when every git tier timed out. A diagnostics variant now reports
whether the answer was verified, and the CLI writes an unverified-fallback note
to stderr. The stdout contract five workflows parse is untouched.

worktree-safety snapshotWorktreeInventory left exists:true when statSync threw,
so a guard that could not check reported the worktree present; exists is now
tri-state and a stat failure surfaces as an 'unverified' finding.
planWorktreePrune reported 'no_worktrees' for a parse failure, which is not the
same as an empty list — and it drives a prune. It now reports 'parse_failed'.

Fixing the inventory change exposed a second fail-open in verify.cts: the
validate-health consumer silently dropped findings whose kind it did not
recognise, so the new kind would have vanished. That is closed too — worth
noting that the survey enumerated producers of degraded verdicts, not consumers
that discard them.

worktree-base-ref and state-transition gain the distinguishing signal without
changing what they do: headAbsenceVerified, and a phase-inventory scan meta.
Whether those guards should ACT differently is a product question this change
does not answer, and both are flagged rather than quietly settled.

rescueSummaryArtifacts is left alone: rescuing on an uncertain cat-file is
deliberate per #2556. It now has tests proving it, and a recorded negative
finding — git cat-file -e returns 128 for both "absent from HEAD" and a fatal
error, so "uncertain" and "certain-and-fine" are not separable at the git
level.

* test(#3057): assert typed values, not rendered text

Ten assertions in the rebuild CLI suite matched substrings of produced output —
STATE.md body fields, a markdown table row, an audit-log heading, and JSON keys
read as text. CONTRIBUTING prohibits that: if the code under test produces
text, the test asserts on its structured surface instead.

No production surface had to be built. Every one already existed and was
already compiled into bin/lib: stateExtractField for body fields,
parseMarkdownTable for the phase table, collectSection for the audit-log
section, and result.data.log — already a typed RebuildLogEntry[]. The tests
were matching rendered text sitting next to the structured data.

One of those assertions was passing for the wrong reason. `stdout.includes
('rebuilt')` matched the JSON KEY name, not a value: the dry-run path emits
`mutated` and the real path emits `rebuilt`, so it would have passed whether
the value was true or false. It now asserts the value.

external-job's refusal already had to name the offending file — that naming is
why the fail-closed variant is survivable rather than a permanent wedge — but
the tests proved it by substring of a prose message. The failure result now
carries offendingPath as its own field and the tests assert it by value. The
human message is unchanged; operators read it.

Array membership is left alone. `phaseIds.includes('99')` and
`result.updated.includes('Completed Phases')` are membership checks on real
arrays, not text matching, and converting them would weaken nothing and clarify
nothing.

* test(#3057): execute acquireStateLock instead of grepping its source

The non-EEXIST lock test asserted on the TEXT of the built .cjs and never
called acquireStateLock. It carried an allow-test-rule: architectural-invariant
exemption to permit that. A source grep proves a literal is present in a file,
not that the behaviour works — it is weaker than a liveness test, which at
least runs the code, and it was the only coverage the fatal-errno path had.

Replaced with tests that inject the errno through fs and assert what actually
happens: a fatal EACCES propagates out of acquireStateLock with zero backoff
sleeps, while EAGAIN/EINTR/EINVAL/EIO/ENOENT/ESTALE/EPERM/EBUSY retry once and
succeed. The exemption is removed and its allowlist entry with it.

One old assertion is deliberately not carried over: it checked the retryable
errnos were expressed as a Set rather than an inline literal. That is a shape
check with no runtime signature; the behavioural tests fail if the code reverts
to the old inline check, which is the regression it was really guarding.

The #3057 lock-body tests move into that same file rather than a new one, which
is what lint-test-file-count asks for and puts every acquireStateLock test in
one place.

* fix(#3057): surface an indeterminate staleness check to its callers

An isolated review caught an inconsistency inside this wave. Two of the three
"add the distinguishing signal" fixes wire through to something a user sees:
git base-branch writes an unverified-fallback diagnostic to stderr, and an
unverifiable worktree surfaces as a W020 finding. The third set
staleCheckIndeterminate on readVerificationStatus's result and nothing read it.

A signal nobody consumes leaves the fail-open exactly as silent as before: the
staleness check could fail and the operator saw precisely what they would see
if the answer were genuinely "not stale". That is the defect this issue exists
to remove, so it is not defensible as scaffolding when its two siblings in the
same change already wire through.

All five callers now surface it, each through the channel it already had rather
than a mechanism imposed uniformly: phase complete adds it to its existing
warnings array and, on the blocked path, as an additive note on the error text;
init and roadmap carry it as a field on output they already emit; the UAT
report carries it without ever gating passed/blockers; workstream inventory
takes an injectable writeDiagnostic mirroring the git base-branch idiom,
because its return shape had nowhere to hang a per-phase field without
rippling the builder's types.

The routing decision is unchanged everywhere. What changes is only that a
caller and an operator can now tell a failed check from a completed one.

That diagnostic carries structured meta rather than being asserted by regex —
the default still writes only the human message to stderr, but tests assert
phaseDir and reason by value. Two earlier assertions in this branch were
converted the same way; this was the last raw-text assertion left.

Also records a scope correction: the completePhaseCore guards now compare
stateReplaceField's result to the body instead of testing truthiness, so a
field whose substitution produced identical text no longer reports as updated.
That is a real behaviour fix, not the signal-only change this file was
described as carrying, and its tests cover both the changed and unchanged
cases.

* test(#3057): bound two heavy subprocesses for a loaded bench, not an idle one

The remote matrix surfaced three failures unrelated to this branch's changes.
All were bad tests, and a re-run would have hidden every one of them.

The reviewer-flags parse block bounded bash -> node -> a full gsd-tools cold
start at 5 seconds. On a bench running thirty thousand tests in parallel that
is not a hang, it is a busy machine. Raised to 30s, matching the convention
sibling suites already use for script invocations, with a comment saying what
the budget covers so nobody tightens it back. Two further copies of the same
5-second spawn in the same file had the identical defect and are raised too —
they were not in the failure report, but they will be next time.

The fragment-propagation test bounded npm run regen:derived — a full build plus
eight generators, the heaviest subprocess in the suite — at five minutes, and
node22 was killed near the end. The captured output proves it: every generator
had written its files and gen:install-tree had emitted all fifteen runtimes
before the kill. Raised to fifteen minutes.

That failure read as `null !== 0`, which says nothing. status null means killed,
not a non-zero exit, and the two want different responses: one is a timeout to
size correctly, the other is a real build break. The assertion now distinguishes
them and names the signal.

Neither test's assertions were weakened and no retry was added. A retry here
would suppress exactly the signal the timeout exists to produce.

* test(#3057): capture fd 1 through the mock tracker, not a raw reassignment

The phase suite reported zero test results on both lanes while running for five
and a half minutes and exiting 1. No assertion text, no stderr, four events for
the whole file: enqueue, start, dequeue, complete. That shape is not a failing
assertion — it is the runner being unable to read the child at all, because it
parses its event stream from the child's stdout.

The cause was the capture helper reassigning fs.writeSync directly. Proven
rather than assumed: a standalone probe patched fs.writeSync and called
process.stdout.write, and the interception fired only when fd 1 resolved to a
FILE, not when it was a pipe. The remote runner captures the event stream to a
file, so a helper that was invisible against a pipe swallowed the reporter's own
output on the bench. That is also why the two sibling suites wired the same way
in this change pass cleanly — they use the mock tracker, the seam io.test.cjs
established for this exact function.

The helper now uses t.mock.method with an explicit restore after each call, so
teardown belongs to node:test rather than a second hand-rolled implementation,
and the interception cannot outlive the one synchronous call it wraps even if
that call throws. Ten call sites thread the test context through; three test
callbacks gained the parameter they lacked.

The three B3 tests are untouched — same assertions, same fault injection. Only
how the context reaches the helper changed.

Refs #3051

* test(#3057): capture phase-complete output from a subprocess, not fd 1

Two attempts to make in-process fd-1 interception safe both failed on the
bench. The suite reported zero test results on either lane while exiting 1 —
four events for the whole file — because the runner parses its event stream
from the child's stdout, and process.stdout.write routes through fs.writeSync
whenever fd 1 resolves to a file, which is how the runner captures. Patching
that seam anywhere in a file can therefore destroy the file's own reporting,
and tightening the window only moved the runtime from 326s to 125s without
recovering a single event.

So the interception is gone rather than tuned. The helper now spawns gsd-tools
as a real subprocess and reads stdout the way the OS already gives it to us,
which is what the rest of the suite does. It asserts the command succeeded
before parsing, so a genuine failure can no longer present as a JSON parse
error.

The two fault-injecting tests could not survive that move as written: a
subprocess cannot see a mock installed in the parent. Instead of reinstating
the interception they now produce the fault on disk — the summary artifact is
created as a dangling symlink, so the staleness check's real statSync throws
inside the child. That is a more honest fixture than a mock in any case, since
it is a condition a user's tree can actually be in. Skipped on Windows, matching
the existing symlink precedent in the write-guard suite.

Three further call sites turned out to depend on parent-process writeFileSync
mocks the subprocess could not see. Those call the CJS function directly, which
is what they always wanted — they never needed stdout at all.

* fix(#3057): one name for one signal, one encoding for one distinction

Standards review found four things this branch introduced, all of them
inconsistencies with itself rather than with the repo.

One upstream bit reached its consumers under three names —
verification_stale_check_indeterminate in two modules, the same value with
"stale" dropped in a third, and stderr only in the fourth. Standardised on the
long name wherever it is a field. The workstream inventory keeps its stderr
channel, since its return shape has nowhere to hang a per-phase field without
rippling the builder's types, but it now says the same word for the same thing.

worktree-safety encoded one three-way distinction two ways in a single file: a
named union for a finding's kind, and boolean|null for an inventory entry's
existence. The second is now a named union too.

Two assertions matched human prose because the blocked and non-blocked
completion paths carried no typed field for the signal. Both now assert typed
values. The first round of this fix added the field but left the regex beside
it, which is the banned pattern sitting next to its own replacement; the second
removed it and added an assertion on the reason enum so nothing was lost.

The remaining two were reasoned away before being fixed, and both reasons were
bad. "No typed surface exists" is the condition CONTRIBUTING says to fix by
adding one — it took three lines. "The file already does this dozens of times"
is not licence to add instance number thirty-one; a convention that violates a
documented rule is debt, not precedent.

Vocabulary differing across DIFFERENT modules is left alone: CONTEXT.md rejects
a single shared result envelope, so per-module shapes are precedented, and a
baseline smell does not outrank a documented standard.

A census of every line this branch adds to a test file now finds no regex or
substring assertion on produced prose: 87 strictEqual, 25 ok (all non-empty or
shape guards), 12 equal, 3 throws (all typed err.code predicates), 3
deepStrictEqual, 2 notStrictEqual.

* test(#2853): add failing-first regression for plan-progress annotation preservation

The count-bump regex's trailing [^\n]+ swallowed the whole Plans line and
the replacement wrote back only the regenerated count, deleting any
hand-written annotation after it. 8-row matrix covers bold/plain forms,
bare template form, executed path, CRLF, and idempotency.

* fix(#2853): preserve hand-written annotations in roadmap plan-progress bump

The count-bump regex's trailing [^\n]+ swallowed the entire Plans line and
the replacement wrote back only the regenerated count, deleting any
hand-written prose after the count (e.g. a gap-closure annotation).

The verb owns the count token only. Capture the existing count token ($2)
and the trailing line text ($3), and rebuild the line as
<label><new count><surviving text>. Trailing text is preserved ONLY when a
real count token preceded it, so the fresh-template bracketed placeholder
(`[Number of plans…]`) is still replaced cleanly rather than glued after
the count (pre-#2853 behaviour on the template path preserved). CRLF \r is
preserved via [^\r\n].

Widens replaceInCurrentMilestone to accept a replacement callback (needed to
branch on whether the count group matched). The bare Plans: checklist header
is still skipped — the lazy match lands on the summary line first and a
count-less bare header yields no count to anchor preservation to.

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.

* 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.

* 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

* 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.

* 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.

d04e287fa9 fix(#2365): stop api-coverage detector false-positiving non-API phases (#2397)
* fix(#2365): stop the api-coverage detector false-positiving non-API phases

detectApiIntegration fired on any integration verb co-occurring anywhere on a
line with any API noun, treated / as a word boundary (so a first-party Next.js
src/app/api/... route path matched the noun "api"), and read any capitalized
word before API/SDK/REST/GraphQL as a service name behind a fixed stopword
denylist (so threat-model prose like "Resolver-only API" fired). Because the
verify:pre seal gate is BLOCKING, a phase touching no external API could not
reach UAT without fabricating a coverage matrix.

The compound rule now requires the verb and noun to share one clause (sentence
punctuation and table-cell walls end a clause) within a bounded word gap.
Non-prose spans are excluded before matching: fenced code (already), inline
code spans (new stripInlineCode in the markdown-sectionizer seam), and
path-shaped tokens. The <Service> API surface rule requires proper-noun
position — a clause-initial capitalized word is ordinary English and needs
dependency evidence (URL / package reference) on the same line — and rejects
compound modifiers ("Resolver-only", lowercase after the hyphen).

A phase that integrates no external API now has a first-class, reasoned way to
say so: a COVERAGE.md containing "No external API integration: <reason>"
satisfies the gate (declaration + rows is contradictory and blocks). The
true-positive path is pinned by regression tests: every default-vocabulary
positive still fires, including the widest word-gap pairing and the
surface-rule-only shape.

Fixes #2365

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

* fix(#2365): tighten api-coverage detector per Codex review (round 2)

Applies the Codex review findings on the initial #2365 fix:

- S-1: a COVERAGE.md "no external API integration" declaration is the human
  override for a fallible detector, so it must PASS even when detection still
  fires — but the contradiction is now SURFACED in the gate output (overridden
  signal count + terms) instead of passing silently.
- S-2: verb/noun pairing is now a term-group nearest-pair merge walk over
  precomputed word ordinals (computeWordStarts / minWordGap), not a match×match
  cross product — a hostile line repeating one pair thousands of times stays
  linear instead of going quadratic.
- FN-4: package-shaped inline-code spans (`stripe-sdk`, `@stripe/stripe-js`)
  are kept as noun/dependency evidence rather than being fully masked, so a
  genuine dependency reference inside code ticks still corroborates.
- C-1: the <Service> API surface rule now scans every candidate in every
  clause; a rejected first candidate no longer shadows a later genuine service.
- Cross-clause binding: a verb may bind a noun in the immediately following
  clause only when its own clause names a service object, within a tight gap —
  admits "Integrate Stripe, exposing its endpoints …" without re-admitting the
  unrelated-clauses false-positive class.
- Internal-descriptor negative evidence ("internal Payments API",
  "the internal endpoint") never pairs; URL/scheme matching generalized beyond
  http(s).

All 5 acceptance criteria still hold: the three reported false positives are
clean and "integrate the Stripe API" still fires. Built .cjs committed
alongside the .cts. tsc + eslint (incl. no-adhoc-markdown-parsing) +
lint:regression-names clean; affected suites 256/256 green.

* fix(#2365): retune api-coverage detector fail-closed per Codex review (round 3)

Codex's second-round review found the round-2 tightening had over-corrected into
FAIL-OPEN false negatives — realistic external-API prose that the BLOCKING seal
gate silently let through (the catastrophic class, since a missed API surface is
worse than a dismissable false positive). Retuned the detector to be explicitly
fail-closed: lean toward detecting, and let the one-line COVERAGE.md "no external
API integration" declaration dismiss the residual false positives.

Fail-open false negatives fixed (all now detect):
- F1 clause-initial `<Service> API` with a plain follower ("Stripe API for
  payment processing") — dropped the follower-allowlist / corroboration gate on
  clause-initial surfaces; a service that is not a stopword, descriptor, or
  compound modifier is a real name from any clause position.
- F2 scheme-less external host ("api.stripe.com/v1") — a dotted host with an
  alphabetic final label now contributes its API nouns; a first-party route
  path (no dotted host) still does not.
- F3 vendor's first-party SDK ("Integrate Shopify's first-party SDK") — the
  compound path no longer filters nouns on "internal"/"first-party" (Codex: the
  qualifier can describe the vendor's own API, not the consuming project's).
- F4 long single integration clause — removed the word-gap cap entirely: it
  could not separate a 21-word genuine clause from an 18-word internal one, so
  the clause boundary is now the whole relationship test.
- F5 lowercase cross-clause service — cross-clause binding no longer requires a
  capitalized "service object".

New false positives fixed (all now clean):
- F6 a URL token that swallowed a trailing clause comma, merging two clauses —
  trailing clause punctuation is kept literal so the split survives.
- F7 a capitalized internal component authorizing cross-clause binding — the new
  gate requires a dependent elaboration, not a new coordinate clause opened by a
  conjunction ("…, then document…").
- F8 a protocol name read as a service ("REST API", "GraphQL API") — protocol
  and locality descriptors are rejected in the `<Service>` position.

- Finding 9: the inline-code-span scanner was O(n^2) on pathological backtick
  runs; rewritten to linear via a per-length run cursor (2 MB: 4.15 s -> ~6 ms),
  semantics preserved (148 sectionizer tests unchanged).

Net simplification: the fail-closed model removed the round-2 minWordGap /
groupByTerm / follower / corroboration machinery (350 insertions vs 445
deletions across the touched files). Under fail-closed, three round-2 negative
tests now correctly detect (integration verb + "internal"-qualified noun, and
the distant-same-clause case); none were trek-e acceptance FPs.

Verified: 1491/1491 unit tests pass; tsc + eslint (incl. no-adhoc-markdown-
parsing) + lint:regression-names clean; all 8 review findings reproduced as
regression tests, both directions. Built .cjs committed alongside the .cts.

* fix(#2365): resolve round-3 Codex review findings (fail-closed, round 4)

Codex's round-3 adversarial review found the fail-closed retune had introduced
new holes in both directions. Resolved:

Fail-open false negatives (now detect):
- External host addressing a PATH ("graph.microsoft.com/v1.0/me") is itself an
  integration surface and contributes an endpoint noun even when the host names
  no vocabulary word. A bare domain link with no path ("https://example.com")
  stays a non-signal, so "Integrate … from example.com, document …" is still
  clean.
- Locality qualification ("internal", "private") no longer leaks across a
  sentence or clause boundary: only plain spaces may separate the descriptor
  from the service, so "The cache is private. Stripe API …" now detects.
- Cross-clause binding: the fragile head-word cap (which could not tell a
  genuine "Connect … to Stripe payments, exposing its endpoints" from an
  unrelated "Integrate … from URL, document …" — both 4 words after the verb)
  is replaced by a participial-continuation rule: a verb binds a noun in the
  next clause only when that clause begins with an "-ing" elaboration. This
  fixes the 4-word-head false negative AND the false positive below at once.

False positives (now clean):
- Cross-clause no longer binds a finite continuation regardless of separator:
  "Wire the settings form. Document endpoint props." / "…; document …" /
  "…, document …" are separate actions, not elaborations.

Perf (quadratic → linear):
- The trailing-punctuation peel is a backward char scan instead of an
  unanchored `[…]+$` regex (16k chars: 156 ms → ~1 ms).
- SERVICE_SURFACE_API_RE bounds the service-name length {1,40} so a hostile
  "A-A-…-x" run cannot drive O(n^2) backtracking (16k: 385 ms → ~3 ms).

Consumer fail-open (blocking gate):
- readPhaseScope now distinguishes "no plans" from a plan that EXISTS but is
  unreadable. On a read error the gate BLOCKS ("could not read the phase
  scope …") instead of silently certifying no-integration from partial scope —
  an unreadable plan could be the one describing the integration.

Documented fail-closed tradeoffs, now pinned with tests so they are not
"fixed" back into a fail-open: a clause-initial capitalized common word before
"API" ("Payment API", "Search API") reads as a service name; a long clause
pairs a verb with a distant noun; and a CommonMark inline code span that wraps
a newline is matched within-line only. Codex judged these acceptable because
the COVERAGE.md declaration is a cheap override.

One documented limitation remains out of scope: "Integrate Stripe, and
authenticate requests with its API" (a coordinate finite clause whose noun
refers back by pronoun) needs coreference resolution, beyond a lexical detector.

Verified: 379/379 affected + command-router tests pass (+14 new regression
tests covering every round-3 finding, both directions); tsc + eslint
(no-adhoc-markdown-parsing) + lint:regression-names clean. Built .cjs committed.

* fix(#2365): simplify to robust core — remove whack-a-mole heuristics (round 5)

Round-4 review confirmed the detector's two most complex features generate
findings in both directions no matter how they are tuned, because they need a
vendor dictionary + coreference the issue rules out in principle. Per the
operator's "ship the robust core" decision, both are removed and their gaps are
documented rather than chased further:

- Cross-clause binding DELETED (allowsCrossClause / participle rule). It caused
  a fail-open on finite continuations ("Integrate Stripe; use its OAuth
  endpoints" — missed) and a false positive on "-ing"-SPELLED nouns ("…, billing
  endpoint terminology…" — wrongly fired). Detection is now same-clause only.
- URL-path-as-evidence REVERTED. Treating every path-bearing URL as an endpoint
  fired on ordinary asset/link URLs ("…/theme.css", "…?next=/x", a docs/repo
  link) and recreated routine UI-phase false positives. An external URL is
  evidence only when it NAMES an API vocabulary word ("api.stripe.com/v1").

Two fail-open cases are now DOCUMENTED limitations, pinned by tests so a future
maintainer does not re-add the heuristics that caused the false positives above:
a service named only in a clause separate from its API noun, and a bare external
host that names no vocabulary word. Both are cheaply covered by the COVERAGE.md
declaration and rare in real phase prose ("integrate the X API").

Also fixed from the round-4 review:
- Qualification now survives markdown emphasis ("The **internal** Payments API"
  stays clean) while still not crossing a sentence/clause boundary.
- readPhaseScope fail-closes on a REAL read failure (EACCES/EIO) enumerating the
  phase directory or reading the roadmap fallback — not only per-plan-file
  failures; a missing directory/section remains a legitimate no-op. The
  declaration-override path surfaces scope_read_error so an incomplete-scope
  override stays visible.
- SERVICE_SURFACE_API_RE length-bound comment no longer overclaims.

Net: the detector is same-clause verb+noun + `<Service> API` surface, with
path/code/inline masking and a fail-closed posture. All five acceptance criteria
hold. 1573/1573 unit tests pass; tsc + eslint (no-adhoc-markdown-parsing) +
lint:regression-names clean. Built .cjs committed.

* fix(#2365): close roadmap-fallback fail-open + stale JSDoc (round-5 review)

The round-5 sanity review confirmed the detector simplification is sound (all
acceptance positives fire, all required negatives clean) and flagged one real
blocker plus a nit:

- Blocker: readPhaseScope's roadmap fallback could still silently pass an
  UNREADABLE roadmap. getRoadmapPhaseWithFallback gated on fs.existsSync(), which
  returns false on EACCES/EIO too — so an unreadable ROADMAP.md read as "absent",
  no exception reached isRealReadFailure, and the blocking gate certified empty
  scope. Fixed at the source: read the roadmap directly and honor the function's
  OWN documented contract — null only on ENOENT (genuinely absent), otherwise
  throw. Both existing callers already wrap it in try/catch expecting that throw,
  and readPhaseScope now fail-closes (blocks) via its roadmap catch. Verified by
  a new e2e test (unreadable roadmap fallback → block).

- Nit: the detectApiIntegration JSDoc still described the removed cross-clause
  participial binding and "every external hostname counts" — corrected to the
  actual same-clause-only behavior and the names-a-vocab-word URL rule.

Verified: full unit suite green; tsc + eslint + lint:regression-names clean.
Built .cjs committed (roadmap.cjs is gitignored/rebuilt, per repo convention).

* chore(#2365): sync generated capability-registry + recapture install goldens

CI surfaced two generated-artifact staleness issues (all failing test shards +
lint-tests traced to these, not to a logic defect):

- gsd-core/bin/lib/capability-registry.cjs was stale: the initial fix edited the
  ai-integration `api-coverage-plan-pre.md` fragment (added the "No external API
  integration" declaration section) but did not regenerate the registry, which
  embeds an inline copy of that fragment. Regenerated via
  `gen-capability-registry.cjs --write` — the diff is exactly the fragment text
  sync. Fixes `lint:generated-sync` and the "committed registry is in sync" +
  "registry integration" tests.

- The 18 golden-install-parity fixtures were stale by exactly one hash line each
  — `gsd-core/references/api-coverage.md`, which this PR edits and which is a
  hashed installed artifact. Recaptured with `UPDATE_GOLDEN=1`; the diff is that
  single hash per runtime and nothing else. Fixes the `golden parity — *` tests.

* test(#2365): flip representative-corpus manifest to assert the fixed behavior

The #2371 representative corpus (merged into next after this branch was cut) is a
known-bug tripwire: it asserts each fixture's currentBuggyOutput so the test
fails loudly the moment #2365 is fixed, at which point — per its own contract in
representative-corpus.test.cjs — the fixer removes currentBuggyOutput so the
assertion checks expectedDetected instead.

This is that moment. Removed currentBuggyOutput from the three detector fixtures
(nextjs-route-path, unrelated-verb-noun, threat-model-prose); the corpus now
asserts detected:false, which the fail-closed same-clause detector satisfies.
Notes updated to describe the fix rather than the bug. The #2366 matrix corpus
is left untouched — that tripwire belongs to its own PR (#2374).

  relies on, `stripInlineCode` and `scanInlineCodeSpans` (glossary is a PR gate).
- Replaced the banned wall-clock assertion in the "hostile repeated-term line"
  test (Clock Seams rule — no elapsed-time asserts) with a deterministic
  signal-count assertion, which also directly verifies the term-dedup that keeps
  pairing linear (one signal for a 10k-pair line, not thousands).
- Rewrote the three fail-closed read-failure tests: instead of chmod 0o000
  (a no-op under root / on Windows, the pattern the repo's IO-failure convention
  avoids) they now exercise the newly-exported `readPhaseScope` in-process and
  inject the failure by monkeypatching fs.readFileSync/readdirSync to throw,
  restoring in finally. Deterministic and platform-independent (no skip needed),
  and they add the ENOENT-is-absence case that the chmod tests couldn't express.

Minor:
- Added limit / limit+1 boundary tests for SERVICE_SURFACE_API_RE's {1,40}
  service-name bound, QUALIFIER_LOOKBACK's 24-char window, and REASON_MAX_LEN
  (200) on the declaration reason.
- Added a fast-check property that fuzzes the tokenizer / clause splitter /
  masking (scanLineTokens, splitClauses, collectTermMatches) with adversarial
  tokens (slashes, backticks, URLs, clause punctuation) and asserts the detector
  is total (never throws), shape-stable, holds detected <=> signals, and is
  deterministic.

readPhaseScope is exported for the in-process tests. Verified: 125 detector +
19 gate tests pass; tsc + eslint + generated-sync (glossary/registry) +
lint-regression-test-names + lint-test-file-count clean.

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.

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

* test(#2143): de-flake the G10 windsurf ReDoS-guard wall-clock assertion

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.

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).
- Leave today() (UTC) as the source for internal/cosmetic stamps.

2f6662d195 fix(#2128): bound the remaining lazy-scan ReDoS vectors (files_modified, Plans-count, <tag>)
A ReDoS-completeness audit surfaced a distinct class beyond the tag/bracket
clause: unbounded `[\s\S]*?` / `[^\]]*` lazy-scans searching for a literal
terminator that may never appear, driven quadratic by REPEATED structures in a
large PLAN.md/ROADMAP.md. Folded all 7 in at maintainer direction:

- files_modified `[^\]]*` -> `[^\]]{0,8000}` (commands.cts, verify.cts): 39.7s -> 0.9s.
- Plans-count `[\s\S]*?` -> section-local `(?:(?!\n#{1,4}\s)[\s\S])*?` — stops at the
  next heading (semantically correct: Plans: belongs to the phase's own section)
  (roadmap.cts x3, phase.cts): 36s -> 4ms.
- <tag> extraction `([\s\S]*?)` -> stop at the next same-tag opening
  `((?:(?!<tag>)[\s\S])*?)` (verify.cts x3, markdown-sectionizer.cts): ~6s -> 2ms.

Every vector is now linear (comprehensively re-measured); real content matches
(end-to-end `roadmap get-phase` still resolves Plans-counted phases). Pre-existing;
byte-behavior preserved for realistic inputs.

b321bc04f4 fix(#2128): bound the sibling bracket-prefix clause — complete the ReDoS fix
Review caught that the prior commit bounded only the paren tag clause and left
the SIBLING bracket-prefix `(?:\[[^\]]+\]\s*)?` (same host regexes, before Phase)
UNBOUNDED — the identical quadratic reachable via a `[...]` run (measured ~16s at
1.7MB). Bound `[^\]]+`/`[^\]]*` -> {1,200}/{0,200} across all 19 phase/milestone
heading prefixes. Comprehensive re-measurement now shows EVERY vector linear
(bracket/paren/id/name/milestone all ~2-44ms at 2.45MB; bracket scaling
2k->2ms, 4k->5ms, 8k->10ms). Also: update the #1729 literal-mirror parity test
off its stale unbounded constant, and add limit-1 (199) boundary coverage.

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.

61f3cafc70 fix(#2126): route roadmap.cts CLI resolvers through shared lookup sources (drives #2114)
Phase 3 of epic #2121. cmdRoadmapGetPhase and getRoadmapPhaseWithFallback now
iterate the shared roadmapPhaseLookupSources (exact -> numeric -> prefix-tolerant,
owned by phase-id.cts since Phase 1) instead of a hand-rolled 2-source lookup, so
all three roadmap resolvers share one resolution contract.

Drives #2114: `roadmap get-phase <bare-N>` now resolves a drifted
`### Phase AB-29:` heading (matching getRoadmapPhaseInternal / init.phase-op),
previously EMPTY from the CLI. The malformed_roadmap checklist-fallback and the
milestone-then-full precedence are preserved (a milestone checklist never blocks
a full-roadmap header match).

Behavior reversal (approved in-session): a bare query now also resolves a
*drifted-only* prefixed heading when no bare sibling exists, reversing the #3599
counter-test's expectation. #3599's real anti-steal intent (a bare sibling wins
over a distinct prefixed one) is preserved by the exact->numeric->prefix-tolerant
ordering and re-asserted in the updated test; a new #2114 block covers the
drifted-only case. Fail-first demonstrated.

bb01f46c6b fix(#2022): gate roadmap update-plan-progress checkbox on verification passed (#2030)
* fix(#2022): gate roadmap update-plan-progress checkbox on verification passed

cmdRoadmapUpdatePlanProgress stamped the phase checkbox + completion date
the moment all summaries landed, with NO verification gate — unlike
cmdPhaseComplete (phase.cts:1436) which checks readVerificationStatus. Since
update-plan-progress is called after every wave and every plan, the checkbox
fired before gsd-verifier confirmed the phase.

- src/roadmap.cts: isComplete now requires summaryCount >= planCount AND

ed31e52b67 fix(#1988): exclude stray non-plan *-SUMMARY.md from phase completion count (#2016)
* fix(#1988): exclude stray non-plan *-SUMMARY.md from phase completion count

Stray remediation/gap-closure summaries (30-FIX-CR02-SUMMARY.md,
30-GAPCLOSURE-SUMMARY.md, …) inflated summary_count, and once
summary_count >= plan_count the phase silently flipped to Complete even
though several plans had no summary. A summary now counts toward completion
only if it pairs with a real plan file.

- core-utils.cts: new countMatchedSummaries(planFiles, summaryFiles) —
  layout-agnostic pairing via the PLAN→SUMMARY marker swap (root/nested/bare)
  plus the <stem>-SUMMARY.md form (bare PLAN.md↔PLAN-SUMMARY.md); the swap is
  applied to the basename only so a 'plans/' dir prefix isn't corrupted.
- plan-scan.cts: scanPhasePlans.summaryCount/.completed use the matched count
  (summaryFiles array still holds every summary on disk for listing/reading).
  Fixes roadmap listing, state sync, verification, workstream inventory.
- roadmap.cts: cmdRoadmapUpdatePlanProgress uses the matched count.
- tests/roadmap.test.cjs: countMatchedSummaries unit tests (root/nested/bare/
  stray) + E2E reproducing the exact #1988 report (4 plans, 1 plan summary,
  3 strays → 1/4 In Progress, NOT Complete).

Closes #1988

* docs(#1988): backfill changeset pr 2016

* test(#1988): strengthen countMatchedSummaries unit tests for mutation coverage

Add direct unit tests for the extended (N-PLAN-MM-slug↔N-MM-SUMMARY), bare
(PLAN↔SUMMARY, PLAN↔PLAN-SUMMARY), legacy (N-PLAN-NN↔N-PLAN-NN-SUMMARY), and
stray-exclusion pairings so every branch of countMatchedSummaries is exercised
(Stryker mutation-score coverage).

* test(#1988): move countMatchedSummaries unit tests into core-utils.test.cjs

The Stryker core-utils shard runs ONLY tests/core-utils.test.cjs (per
scripts/mutation-matrix.cjs), so the unit tests for countMatchedSummaries
must live there to be mutation-covered (previously in roadmap.test.cjs, the
shard never ran them → mutants survived → Stryker gate failed). The E2E
#1988 reproduction stays in roadmap.test.cjs. Added an absolute-path case to
guard the lastIndexOf('/') >= 0 boundary.

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).

18995380ce feat(#1154): honest verifier — abstain (insufficient_spec) on non-inferable backstop truths (#1738)
* feat(verify-phase): honest verifier — abstain (insufficient_spec) on non-inferable backstop truths (#1154)

Carry the edge-probe's existing `backstop` (non-inferable) tier through the
plan-phase projection as a structured flat-scalar marker instead of a prose
parenthetical, and make verify-phase abstain -> human_needed (never silent-pass)
on a backstop truth it cannot confirm with explicit evidence. Truth-axis mirror
of #644's prohibition judgment-tier (ADR-550 D4).

Engine (deterministic, CI-tested per ADR-550 D5 — never the LLM verdict):
- src/probe-core.cts: truthStatement/truthVerification normalizers, projectTruths
  (conservative serializer), dispositionForUnverifiableTruth (backstop+no-evidence
  -> unverified/flagged/insufficient_spec; backstop+evidence -> green; inferable
  -> green, the over-abstention guard).
- src/roadmap.cts: coerceTruthToString now reads `statement` first so an object-form
  backstop truth is surfaced, not dropped (Hyrum backward-compat for truth-readers).

Workflow/agent/docs: plan-phase emits the structured marker (flat scalar, ADR-550
#1278); verify-phase + gsd-verifier add the abstain arm; new references/honest-verifier.md;
FEATURES/COMMANDS document insufficient_spec; ADR-550 amended (truth-axis D4 mirror).

Decisions adopted (trek-e review): insufficient_spec feeds existing human_needed with a
distinguishable reason (no new VERIFIER_STATUS); changeset Changed; round-trip parity
test; abstain-on-unconfirmed-backstop regression test red-first.

Implementation notes (deviations from the issue's proposed file list, verified live):
- frontmatter.cts needs no change — its flat parser already round-trips object-form truths.
- verify.cts needs no change — it grades artifacts/key_links structurally; truths are
  LLM-graded at the workflow layer, so consumption lives there + the deterministic helper.
- No CJS<->SDK hand-sync — the SDK seam was retired (ADR-0174); src/*.cts is sole source.

Regenerated artifacts: golden-install-parity fixtures, INVENTORY-MANIFEST, size baselines.

* chore(#1154): add changeset (Changed) for honest verifier

User-facing changelog fragment for #1738. Typed `Changed` (not `Added`) per
trek-e review condition 3 — the verify behavior shifts for backstop-bearing specs
(a confident silent `passed` becomes `human_needed`), which is user-visible even
though the schema marker is additive.

* docs(#1154): score-formula also excludes abstained insufficient_spec truths (review nit-1)

trek-e review nit: the verify-phase score sentence said PRESENT_BEHAVIOR_UNVERIFIED
truths were "the only ones excluded" from verified_truths. Post-#1154 an abstained
`insufficient_spec` backstop truth is also excluded (it is not ✓ VERIFIED and routes
to human_needed). Behavior was already correct; this tightens the wording.
Regenerated golden-install-parity fixtures + workflow-size baseline for the touched
verify-phase.md. (Nit-2 — a dedicated insufficient_spec_items frontmatter list — is
intentionally not taken: the current design is ADR-550-D4-conformant, the abstain
cause rides as a distinguishable report reason, and adding it would exceed the
approved scope.)

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.

dee40cd392 fix(#1551): match dash-separated milestone phase IDs in roadmap analyze checklist scan (#1552)
* fix(#1551): match dash-separated milestone phase IDs in roadmap analyze checklist scan

The checklist scanner in cmdRoadmapAnalyze allowed only a dot separator
(?:\.\d+)* while the detail-heading scanner allows [.-], so milestone-prefixed
IDs (1-01) truncated at the dash (-> 1) and reported phantom missing detail
sections on every well-formed milestone roadmap. Widen the char class to
(?:[.-]\d+)* to match the detail scanner and the shared phaseMarkdownRegexSource
helper.

Fixes #1551

645601a10d refactor(#1286): T4 — migrate 5 large destructure callers off the core spine (batch 3) (#1287)
Migrate the entire core surface of commands (~23 symbols), phase (~17),
roadmap, state, template to the leaf modules directly (behaviour-identical —
leaves are the objects core re-exports by reference). All 5 now import zero
core symbols and are removed from the allowlist (9 -> 4). Dropped a dead
`void replaceInCurrentMilestone` from phase.cts; stale core.cjs docstrings
fixed. core.cts re-exports untouched (serve the remaining 4 idiom-hard
files); teardown is T-final. No behaviour change.

Closes #1286
