6b7df61938 enhance(#3881): one YAML parser — vendored js-yaml replaces the hand-rolled dialect (#3888)
* docs(#3881): answer §8.1's open question and correct three wrong premises

ADR-3473 §8.1 carries a blocking open question with a forcing function: it must
be answered before any implementation PR for the rule opens. Answered here as (a),
a string-coercing adapter, with the measurement that settles it.

The sequencing note bet that §8.8's schema would make (b) tractable. Measured
against merged reality it does not: only 33 of extractFrontmatter's 78 non-test
call sites read STATE.md, and two of the five compensating mechanisms §8.1 lists
survive real types, leaving ~31 lines across 3 call sites as the actual prize.

Also corrects three claims verified false while answering it. §8.1's justifying
sentence names #3349 and #3360 as defects a real parser would fix; both are
already fixed on next, confirmed by executing the compiled parser rather than
reading it. The guard roster calls lint-frontmatter-scalar-broad-grep.cjs an
expected casualty of this rule, but it guards shell grep idioms in workflow bash
fences and never touches our parser. The same roster calls lint-vendored-deps.cjs
reusable as-is; it is hardcoded to re2js throughout.

The last two were caught by applying the rule this amendment records -- a factual
claim in this ADR is a hypothesis until the implementing phase executes it -- on
its first use.

* docs(#3881): record that §8.1's fork is ill-posed and (a) is not implementable

An adversarial pass on the Phase 4 design established by execution that
extractFrontmatter is not a YAML parser but a line-oriented scanner whose output
is a function of raw source text. Four spellings of the same value collapse to
one js-yaml tree but produce four distinct legacy strings, one of them mangled.
No adapter over a tree can choose among outputs the tree does not distinguish,
so fork (a) -- keep a string-coercing adapter so the existing contract holds --
cannot be built. For any document with a non-scalar value, (a) collapses into
(b); about 26 percent of frontmatter-carrying documents have one.

Also records three design defects and one new attack surface, all confirmed by
execution: catching a parse failure and returning {} would delete the frontmatter
block on the next write at eight call sites that conflate empty with unparseable;
an empty value yields null where legacy yields {}, and reconstructFrontmatter
omits null-valued keys, so the shipped state template's empty progress key would
vanish; the #1882 truncation probe is parseYamlRegion itself rather than a
pre-parse heuristic, so it cannot both stay unchanged and survive that deletion;
and FAILSAFE_SCHEMA still resolves aliases, expanding seven lines to 22.8 MB.

The rule is not deferred. The measurement is the deliverable and the re-scoping
is recorded as an open question with a forcing function, per section 8's own rule.

* test(#3881): failing-first rows for block scalars, unicode keys and the missing #3594 matrix

Creates tests/feat-3594-parser-adversarial-frontmatter.test.cjs, the file the fixture README instructs contributors to register fixtures in but which never existed.

Section C: table-driven ownership check over tests/fixtures/adversarial/frontmatter/ so a fixture with no matrix entry fails loudly; six existing fixtures (duplicate-keys, crlf-mixed, unclosed-block, unicode-keys-and-values, null-byte-value, huge-bounded) each get the invariant its README states.

B1 blockScalarValueIsNotTheBlockIndicator: parsing commands/gsd/add-tests.md must give argument-instructions the instruction text, not the literal '|'. RED today.

B2 blockScalarDoesNotInventATopLevelKey: same parse must not produce a top-level Example key scraped from inside the block body. RED today.

B3 unicodeKeyRoundTripsAsIs: the 相 key in unicode-keys-and-values.md must survive parsing; today it is silently dropped. RED today.

* chore(#3881): vendor js-yaml and generalize the vendored-deps guard to a manifest

Packaging step for ADR-3473 §8.1: makes js-yaml available to gsd-core/bin/** without promoting it out of devDependencies (promoting broke every installed tree, #3496).

gsd-core/bin/lib/vendor/js-yaml.cjs is a verbatim copy of node_modules/js-yaml/dist/js-yaml.js (the self-contained UMD dist bundle, not index.js), exposing load/dump/FAILSAFE_SCHEMA/YAMLException with zero require() calls of its own.

src/vendor/js-yaml.d.cts is hand-authored, not copied, because js-yaml ships no upstream .d.ts and @types/js-yaml is not installed. It is deliberately narrow, declaring only the four symbols in use, so anchors/aliases/custom types/loadAll are unreachable from typed code -- a compile-time enforcement of ADR-3473 §8.1's refusal to expand alias resolution for security reasons. Because it has no upstream counterpart it is excluded from the byte-compare.

scripts/lint-vendored-deps.cjs is refactored from a script hardcoded to re2js into a table-driven VENDORED manifest (one row per package: upstream/vendored .cjs paths, optional .d.cts paths, twin kind upstream-verbatim vs hand-authored) so a second vendored package does not require a second hardcoded check block, per ADR-3473 §8.3 'one implementation per rule'. The four existing re2js checks (vendored .cjs vs node_modules, vendored .d.cts vs node_modules, src/vendor twin vs bin-side twin, devDependency version pin vs installed version) are preserved unchanged; verified pass/fail identical before and after the refactor, and the guard's ability to fail was re-proven with a deliberate one-byte append to both re2js.cjs and js-yaml.cjs, then restored.

docs/INVENTORY.md and docs/INVENTORY-MANIFEST.json (via gen-inventory-manifest.cjs --write, run after build:lib) register vendor/js-yaml.cjs. gsd-core/bin/lib/vendor/README.md documents both vendored packages and the two twin kinds.

* feat(#3881): parse .planning frontmatter with the vendored js-yaml

ADR-3473 §8.1: extractFrontmatter's read path is no longer a hand-rolled
line scanner. parseYamlRegion, escapeDoubleQuoted, unescapeDoubleQuoted and
parseQuotedScalar are deleted (not patched); parsing now goes through the
vendored js-yaml (./vendor/js-yaml.cjs) under { schema: FAILSAFE_SCHEMA,
json: true }. Everything js-yaml does not do is layered on top, in one
place, carrying the seven design-doc consequences:

1. Empty value: a null js-yaml value is coerced to {} (matching legacy's
   own empty-value contract) so reconstructFrontmatter — which omits
   null-valued keys — still round-trips a bare `key:` line instead of
   deleting it. Verified live: progress: with no value survives
   parse -> reconstruct -> re-parse.

2. Unparseable no longer collapses to a bare {}: a new FRONTMATTER_UNPARSEABLE
   Symbol (exported), keyed exactly like the existing #3257 FULL_LINE_COMMENTS
   channel, is carried on the {} returned for malformed/refused YAML. Invisible
   to Object.keys/entries/JSON.stringify/for-in, so the 70 call sites that
   never inspect it are unaffected; wiring the 8 hasFrontmatter sites to
   consult it is a separate change, not done here.

3. Non-scalar object-list items (the four spellings of `- test: a b` that
   js-yaml collapses into one tree shape) are rendered as a canonical
   `key: value[, key2: value2]` string per item, keeping the existing
   array-of-strings value SHAPE. A full corpus differential over all 1702
   tracked markdown files found 11 residual divergences from the legacy
   parser (enumerated in the PR/report), most of them the parser now being
   MORE correct (a dropped quoted top-level key, the block-scalar/phantom-key
   defect, a dropped Unicode key).

4. The #1882 truncation probe still runs the one real parser, but derives
   its key count from js-yaml's own thrown error and mark.line when the
   whole region doesn't parse cleanly (the dominant real truncation shape:
   fence opened, well-formed keys, no closing fence). Verified against both
   the clean-parse and the exception-fallback path.

5. The #3257 comment channel now attributes each pending column-0 comment
   against js-yaml's own parsed top-level key list (matched by literal key
   text, in document order) instead of the legacy ASCII-only key regex, so
   a comment above a Unicode key attaches correctly.

6. Anchors, aliases and merge keys are refused outright (a raw-text
   pre-scan, since FAILSAFE_SCHEMA still resolves them) — corpus occurrences
   today: zero. A 7-line billion-laughs fixture is verified refused rather
   than expanded.

7. A literal U+0000 is swapped for a private-use sentinel before the parse
   and restored in every resulting string afterward, since js-yaml rejects
   NUL unconditionally under every schema.

escapeDoubleQuoted is deleted and reimplemented via js-yaml's dump()
(forced double-quoted style), with control-char hex escapes lowercased to
keep serialized output byte-stable (#1779 emitted lowercase); it keeps its
exported name and signature for its two other call sites (commands.cts,
runtime-artifact-conversion.cts), which need no change.

frontmatterDeepEqual, the comment channel, sliceTopLevelFrontmatterSegments,
regenerateFrontmatterKey's guard, noOpObjectListSetError and
parseMustHavesBlock are all unchanged — retiring them is fork (b) and is
not this phase.

* fix(#3881): quote template placeholders and preserve unparseable frontmatter

SECURITY.md/UI-SPEC.md/VALIDATION.md wrote frontmatter placeholders as
bare {N}/{phase-slug}/{date}, which is valid YAML flow-mapping syntax
under the vendored js-yaml parser, not the literal placeholder text
intended. Quote them so they parse as strings.

Wire the FRONTMATTER_UNPARSEABLE Symbol (exported but unused) at the
8 call sites in state.cts/state-transition.cts that compute
hasFrontmatter via Object.keys(extractFrontmatter(...)).length > 0 and
reassemble the document without a frontmatter block when false. That
check conflated 'no frontmatter' with 'unparseable frontmatter' (both
parse to {}), so a document with a merge-conflict marker or refused
alias in its frontmatter had that block silently dropped on write.
Each site now preserves the exact raw bytes stripFrontmatter removed
when the marker is set, leaving the genuinely-empty case unchanged.

* docs(#3881): correct the frontmatter glossary entry

Two errors in the entry as first written: it named parseYamlRegion as part of
the read path when that function is deleted, and it recorded the eight
hasFrontmatter call sites as unwired follow-on work when they were wired in
e35ac2a2c. Also records the scope caveat that the CLI write path rebuilds the
frontmatter block independently, so the marker binds at the transform layer.

* docs(#3881): record the semantic-migration decision and the counted guard ledger

The maintainer chose the full semantic migration over splitting the rule into
its own epic or patching the scanner, so section 8.1 is answered as "the fork
was ill-posed and the migration is semantic" rather than as (a) or (b).

Also replaces the pre-implementation guess that this phase would shrink the
guard surface with the counted result: excluding vendored third-party lines the
hand-maintained surface is net +307, and frontmatter.cts grew by 68 lines
despite four functions being deleted, because the compatibility layer over
js-yaml is larger than the scanner it replaced. Section 8.1's stated benefit is
therefore not delivered as written; what improved is the kind of code
maintained, not the amount. Decision 6 requires recording that rather than
netting it away.

* fix(#3881): refuse anchors structurally and fold in review findings

ADR-3473 §8.1 review findings, addressed inline:

Finding 1 (BLOCKER): refuseAnchorsAndAliases was a raw-line regex that matched
only the bare-key spelling (key: &x). A quoted key ("a": &x), a flow mapping
({b: &x}) and a flow sequence ([&x, *x]) all define/use the SAME anchor
mechanics while never matching that line shape, so the exact expansion the
guard exists to stop went straight through unrefused (a 303-byte quoted-key
bomb expanded to ~35.8MB). Replaced with js-yaml's own `load` `listener`
callback, which reports `state.anchor` for every event belonging to an
anchored node in every spelling, and throws from inside the callback to abort
before any expansion (~1-2ms vs full expand-then-discard). A merge key with
an alias is still refused (merge always requires a previously anchored node,
so the alias itself trips the listener); a bare merge key with NO alias is no
longer separately refused, documented as intentional: FAILSAFE_SCHEMA never
resolves `!!merge`, so it carries no expansion risk. Table-driven tests added
for all four bypass spellings + merge key, plus a quoted-key-spelled
billion-laughs fixture registered in the adversarial matrix and README.

Finding 2: src/vendor/js-yaml.d.cts's docblock falsely claimed anchors/
aliases were "simply UNREACHABLE from typed code" through the twin. Corrected
to state the truth: anchor/alias resolution is document-level `load`
mechanics reachable through exactly the declared surface, and refusal is
enforced at RUNTIME (Finding 1's listener), not by the type surface.

Finding 3 (MAJOR): the null-byte sentinel (U+E000) round-trip was
non-injective — restoreNullBytesDeep rewrote every U+E000 in the parsed tree
back to NUL, including one the document author legitimately wrote, silently
corrupting it. Now refuses outright whenever the raw region already contains
U+E000 (consistent with the existing anchor/merge-key refusal path), making
the substitution provably injective. Tests added for a real NUL alone
(preserved), a pre-existing U+E000 alone (refused, not corrupted), and both
together (refused, not merged into one byte).

Finding 4 (MAJOR): scripts/lint-vendored-deps.cjs's `srcTwin` field was dead
for a hand-authored row (only read inside the upstream-verbatim branch) —
exactly how Finding 2's stale docblock drifted unnoticed. Added
checkHandAuthoredTwin: every value-level export the twin DECLARES must be an
actual own property of the vendored runtime module at require-time. Tests
added, including a sensor that a declared-but-nonexistent export IS caught.

Finding 5: the existingFm/hasFrontmatter/stripFrontmatter/fmPrefix/
unparseableFm/reassemble preamble, copy-pasted at 7 sites in
state-transition.cts plus a sixth hand-inlined copy in state.cts's
cmdStateCompletePhase, is now one exported helper
(beginFrontmatterReassembly) every site routes through, including the
hand-inlined one. Three call sites (beginPhaseCore, patchCore, updateCore)
keep a literal `body = stripFrontmatter(content)` assignment alongside the
helper call so scripts/lint-state-write-path-drift.cjs's single-hop backward
scan (which does not chase aliases) still sees the strip; stripFrontmatter is
pure/idempotent so the extra call changes nothing observable.

Finding 6: corrected the frontmatter.cts docblock's stale "wiring is a
separate change" claim (the 8 call sites are wired on this branch) and the
changeset's backlink from (#3473) to (#3881).

Finding 7: fixed the lint:ci failures blocking the gate — an
@typescript-eslint/only-throw-error violation from throwing a bare Symbol as
the anchor-detected signal (now a real Error subclass), unused-var warnings
left over from the Finding 5 refactor, a lint-test-file-count cap exceeded by
two migration-specific test files (allowlisted with justification), and the
lint-state-write-path-drift false positive from Finding 5's helper (fixed
above). tests/frontmatter-golden-parity.test.cjs:117's execFileSync already
carried an explicit timeout; no change was needed there.

Golden fixture: added a golden entry for the new
anchor-alias-bomb-quoted.md fixture ({} — matches what the legacy line
scanner would also produce, since it independently dropped every quoted
top-level key). No other corpus document diverges: real .planning/ documents
carry zero anchors/aliases/merge keys/U+E000 today.

Refs #3881

* fix(#3881): fold in second-round review findings

Finding 1 (BLOCKER): tests/frontmatter.test.cjs pinned the pre-migration
ASCII-only key regex for the Unicode fixture; updated to require the 相
key's value now that js-yaml has no such restriction. Audited the rest of
the file for other pre-migration pins (block scalars, quoted keys,
flattened values, empty values, duplicate keys, unclosed blocks, null
bytes) by execution against real fixtures; found none regressed.

Finding 2: parseYamlRegion and escapeDoubleQuoted renamed to
parseGuardedYamlRegion and escapeDoubleQuotedScalar in src/frontmatter.cts
so no function still answers to the deleted hand-rolled scanner's name
(ADR-3473 §8.1 "deleted, not patched"). escapeDoubleQuotedScalar's three
external call sites (src/commands.cts, src/runtime-artifact-conversion.cts)
updated in the same change — a mechanical rename, not an ADR-amendment
matter.

Finding 3 (BLOCKER): fixed a real crash and a silent data-loss bug found
by execution. A top-level key named constructor/__proto__/toString/
valueOf/hasOwnProperty crashed reconstructFrontmatter (bracket read
resolving an inherited Object.prototype member); a key literally named
__proto__ was silently DROPPED entirely (bracket assignment on an
ordinary {} invoked the inherited __proto__ setter instead of creating a
data property). Fixed by building every parsed Frontmatter object with
Object.create(null), and replacing an `in` check with hasOwnProperty.call
in propagateCommentChannel. Added round-trip tests for all five hostile
keys, each with its own leading comment.

Finding 4 (MAJOR): escapeDoubleQuotedScalar's docstring falsely claimed
full byte-stability across the migration. Verified by execution: BEL/NUL/
NEL/NBSP/LS/PS/BOM now emit YAML-named escapes instead of the old hex/raw-
literal forms. Proved round-trip equivalence (each escape re-parses to the
exact source codepoint) and corrected the docstring. Found and fixed a
related real defect while verifying: a lone UTF-16 surrogate was emitted
BARE (scalarNeedsDoubleQuoting didn't trigger), producing genuinely
unparseable YAML that silently collapsed to {} on re-read — extended
scalarNeedsDoubleQuoting to route surrogates through the quoted+escaped
path.

Finding 5 (MAJOR): countKeysBeforeTruncation went silent on 4 real
truncation shapes (unquoted colon, open flow collection, mis-indented
sibling key, refused anchor). Root cause: the mark-based prefix recovery
excluded the very line whose key needed counting, and a mark-less refusal
never entered the recovery branch at all. Fixed by taking the max of two
lower bounds: the longest parser-verified line-prefix, and a raw-text
count of key-shaped lines (reusing the same key-shape pattern this file
already uses for isFrontmatterShaped). Extended test-matrix row A5
table-driven over all 4 regressed shapes.

Finding 6: the design doc's claim that no test owned the #3594 adversarial
fixture corpus was false — consolidation epic #1969 had already folded it
into tests/frontmatter.test.cjs. An earlier commit on this branch
re-created a standalone duplicate under that false premise; folded its
genuinely-new coverage (fixture-ownership check, anchor-bomb fixtures,
block-scalar B1/B2 rows) into frontmatter.test.cjs and deleted the
duplicate file. Corrected the false claims in 40-design.md §3.3.1 and the
ADR's §8.1 note, including the roadmap-sibling claim (no such file exists).

Finding 7: the golden serializer sorted object keys, making it structurally
blind to the key-order-parity invariant ADR-3473 §8.1 actually claims.
Made it order-preserving and regenerated the golden fixture from a
standalone compile of the legacy (pre-#3881) parser at ddde001af; the
current parser matches it with zero undocumented divergences, confirming
key-order parity genuinely holds. Extended row A2 table-driven across 6 of
the remaining 7 transitionCore kinds (all pass) plus documented, by
execution, a newly-discovered 8th-site regression: state.cts's
cmdStateCompletePhase calls the same preservation helper but its result is
clobbered by a later unconditional resync — filed as a distinct finding
rather than fixed here (touches syncAndPreserveStateMd, outside this
change's verified scope).

Refs #3881

* fix(#3881): preserve unparseable frontmatter through the CLI write path

Characterization (executed, before/after shown): case (b), not (a). The
frontmatter FENCE survives — `state complete-phase` on a conflict-marked
STATE.md returns success and a well-formed, freshly-derived frontmatter
block, not a document with no frontmatter at all. But the block's actual
content (the merge-conflict markers, and with them any signal to a human
that the document was in conflict) is silently discarded and replaced.

Root cause was two clobber sites, not one:

1. syncStateFrontmatter (src/state.cts) re-parses the already-preserved
   `transformedContent` from readModifyWriteStateMd, finds {} + the
   FRONTMATTER_UNPARSEABLE marker, and unconditionally rebuilt a fresh
   frontmatter block from the body anyway.
2. Even after (1) is fixed, applyPostSyncPreservation's own
   postFm/applyStatePreservation/authoritativeFm-reassertion machinery
   re-extracts frontmatter from syncedContent, restores curated fields
   from the pre-write snapshot, and reconstructs a NEW block again —
   confirmed live via `state begin-phase`, which still lost the markers
   after fixing (1) alone.

Both are now guarded by the same predicate (isUnparseableFrontmatter,
checking FRONTMATTER_UNPARSEABLE): when the ORIGINAL frontmatter did not
parse and the caller is not on ADR-3408 §8.3's closed "body wins" list,
both functions return their input content unchanged rather than
re-deriving over it. The closed list (cmdStateSync #905,
/gsd-health --repair's REGENERATE_STATE, both routed only through
writeStateMd, which never reaches applyPostSyncPreservation and passes
sanctionedPermanentEmptyFallback=true to syncStateFrontmatter) is
untouched — neither widened nor narrowed; verified by execution that
`state sync` still overwrites the conflict-marked block exactly as before.

Other verbs sharing the same readModifyWriteStateMd path were checked and
were equally affected before this fix: state update, query state.patch,
and state begin-phase all lost the conflict markers (RED, shown by
execution), and all three now preserve them (GREEN). Covered table-driven
in tests/feat-3881-yaml-parser-consequences.test.cjs's new A2b describe
block, which drives the real CLI verbs via runGsdTools — not just the pure
transitionCore layer the earlier A2 rows exercised — plus a control
asserting state sync's body-wins contract is unchanged.

Refs #3881

* fix(#3881): restore the parse surface's prototype and fix remote-runner failures

Root cause of the bulk of the 88 remote-runner failures: extractFrontmatter/parseGuardedYamlRegion handed back Object.create(null) trees for prototype-pollution safety, but assert.deepStrictEqual compares prototypes, so every assertion against a plain object literal failed (57 frontmatter.unit.test.cjs + 5 frontmatter.test.cjs + others). Fixed by keeping the internal construction null-prototype (unchanged) and converting to a plain-prototype tree via Object.defineProperty (never bracket assignment, so __proto__/constructor/toString keys stay safe) at the parseGuardedYamlRegion/unparseableResult return boundary only; the internal FULL_LINE_COMMENTS Symbol channel is copied by reference, not recursed, so its own __proto__-safety is untouched.

Per-class fixes: (1) bomAcrossArtifactTypes was the same prototype bug, no separate code change needed. (2) frontmatter-cli #1660: added objectListFieldWouldLoseData, a broader lossy-field detector alongside the existing byte-identical noOpObjectListSetError -- js-yaml's flattenObjectListItem now correctly includes every sub-key of an object-list item (a real bug fix over the legacy scanner, which silently dropped every field but the first), so a set that drops that now-included data is no longer byte-identical to the original and needs its own guard. (3) uat.test.cjs: updated the pinned expectation for the human_verification quote-stripping artifact -- js-yaml resolves quoting correctly where the legacy regex left an unbalanced quote; documented as an intentional, non-lossy behavior change. (4) smart-entry: added a fallback-only loadWithAmbiguousColonRepair so a column-0 key: value line whose value itself contains an unquoted colon (the #2571 hand-edited-STATE.md shape) round-trips instead of failing the whole frontmatter block closed. (5) frontmatter.unit.test.cjs bracket-array leniency: added a second fallback, repairMalformedInlineArrays, restoring the legacy scanner's tolerant inline-array handling (consecutive/blank commas, unclosed bracket) -- both repairs run ONLY after the primary parse already threw, so well-formed documents are unaffected. (6) prompt-injection-scan: src/frontmatter.cts had a literal U+FEFF BOM embedded in a comment illustrating the #2977 fix; replaced with the U+FEFF text escape. (7) eslint-glob-coverage: allowlisted the new src/vendor/js-yaml.d.cts vendored type declaration, same precedent as the existing re2js.d.cts entry. (8) frontmatter-golden-parity: git ls-files *.md now runs with -c safe.directory=* (process-scoped) so it survives the remote runner's dubious-ownership check without a persistent git config write.

* chore(#3881): backfill changeset PR number

Refs #3881

* test(#3881): make golden parity resistant to unrelated tree churn

A corpus-wide snapshot keyed to every tracked *.md file was coupled to mutable-by-design files: .changeset/*.md's pr:0 -> real-PR-number backfill is a required workflow step, not a parser change, yet it turned this suite red. Training people to 'just regenerate the golden' on that kind of failure defeats the point of the snapshot. Exclude .changeset/** from the golden corpus entirely, tolerate tracked *.md files with no golden entry (they postdate the capture) instead of failing on them, keep hard failures for a golden entry whose file has vanished from the tree and for any real parity divergence, and add a coverage floor so the enumeration cannot quietly degrade to comparing a handful of files. Golden regenerated by recompiling the legacy pre-migration parser (git show ddde001af:src/frontmatter.cts) standalone, independent of the current parser, over the same non-changeset corpus.

Refs #3881

* test(#3881): make the parser golden hermetic instead of tree-keyed

This repo merges ~21 commits/day; a 14-day sample measured 937 touches of the
exact files (commands/gsd/*.md, gsd-core/workflows/*.md, agents/*.md,
docs/*.md) the prior golden pinned by tracked path. Any PR editing one of
those files' frontmatter for reasons unrelated to the parser (an
argument-hint addition, an allowed-tools tweak) turned the suite red, and the
reflex fix -- "regenerate the golden" -- overwrote the very snapshot meant to
catch a real regression. Excluding .changeset/** was not enough; the design
itself was wrong: a regression fixture must not be keyed to mutable repo
paths, and a single 376-entry JSON every such PR touches is also a
guaranteed merge-conflict surface.

Rebuilt the fixture to carry its own documents: each of 51 entries stores a
stable id, literal documentText (shrunk from a real ddde001af-era corpus
document), and an expectedParse captured independently from the
pre-migration legacy parser (git show ddde001af:src/frontmatter.cts,
compiled standalone against its byte-identical sibling modules). The test
reads no tracked path, shells out to no git command, and enumerates no tree
-- a PR editing commands/gsd/help.md cannot affect it. Every entry's
reconstruction was verified at capture time to reproduce both the current
and legacy parser's output on the original document; 0 of 51 candidates
were dropped by that check (1, the deliberately-unterminated
unclosed-block.md adversarial fixture, has no closing fence to truncate at
and is stored unshrunk). Kept the 5 documented DIVERGENCES rows (now
diverges:true entries) and the D2 order-preserving structural serializer
that keeps the comparison from passing vacuously; dropped the
tree-enumeration helpers, the coverage floor, the post-capture-skip logic,
and the vanished-file check -- all artifacts of the path-keyed design.

* fix(#3881): resolve vendored-deps paths independently of cwd shape

Five rows in tests/lint-vendored-deps-manifest.test.cjs failed on
windows-latest CI: the test passed absolute scratch-file paths into
compareFiles()/checkRow(), whose helpers joined every input onto ROOT
via path.join(ROOT, rel), producing garbage when the input was already
absolute. It surfaced on windows-latest specifically because GitHub's
Windows runners checkout the repo on a different drive than TEMP, so
path.relative(REPO_ROOT, tmpFile) returned the absolute path unchanged
(no relative traversal is representable across drives) rather than the
relative form the test assumed. The remote gsd-test runner this repo
gates pushes on is Linux-only and could never have caught this;
GitHub CI's windows-latest job is the only signal that does, and it did.

Fixed the helper itself (scripts/lint-vendored-deps.cjs's new
resolvePath()) to treat an already-absolute input as absolute-in,
absolute-out instead of silently mis-joining it, and updated the test
to pass the scratch file's absolute path directly rather than relying
on a relative conversion that is not always representable. Kept every
mutation-sensor assertion intact and added coverage proving
resolvePath is a no-op for relative inputs and correctly passes
absolute ones through unchanged.

* fix(#3881): warn when state sync regenerates over unparseable frontmatter

state sync (ADR-3408 §8.3's sanctioned regenerate path) correctly
overwrites an unparseable frontmatter block per its 'body wins'
contract — that overwrite behavior is unchanged here. The defect was
the silence: synced:true/exit 0 gave no signal that the existing
block (including git merge-conflict markers) could not be parsed and
was destroyed, per ADR-3473 §8.5 ('a derived conclusion may not be
reported as authoritative when the derivation dropped input it could
not resolve') and §8.4 ('failure is a value').

Adds a gsd: warning — ... (#3881) line on stderr, matching the
existing #3573 precedent, and surfaces the same disclosure in the
JSON result's existing changes[] array so a machine consumer sees it
too. Exit code and synced:true are left unchanged — sync did what its
contract says.

REGENERATE_STATE (/gsd-health --repair's sibling on the same
sanctioned-regenerate list) is DESTRUCTIVE-risk and unconditionally
refused by applyRepairs's dispatcher before runRepairAction ever runs
(src/health-diagnostic.cts), so it is not a live path today and is not
in scope for this fix.

* revert(#3881): restore exit-0 result envelopes for state errors

Reverts 9638f2936 and its changeset. The change was wrong and the revert is
the correction.

This repo distinguishes two error mechanisms deliberately. error() in
src/io.cts writes to stderr and calls process.exit(1) -- the hard-failure
path. output({error: ...}) writes a JSON result envelope to stdout and returns
normally with exit 0. The reverted commit converted 23 result-envelope sites
into hard failures, which is a different contract, not a bug fix.

tests/state-contract.test.cjs's errorPathDoesNotPublish asserts the envelope
contract directly -- a failing command exits 0 with a JSON error envelope and
must not publish state.json -- and the remote matrix run caught it along with
four cases in the QA scenario walk. Thirteen tests in tests/state.test.cjs that
the original commit rewrote were encoding that real contract, not the bug it
claimed; they are restored.

Whether an error envelope on stdout with exit 0 is the right CLI design is a
genuine question, and it is section 8.4's rule ('failure is a value') with its
own phase. It is not something to flip inside this PR.

* test(#3881): keep the frontmatter mutation shard inside its time budget

The Stryker (frontmatter) shard hit the documented 15-minute (900s) shard
cap. Root cause is NOT row-level spawn overhead (contrast the #2790/
core-utils precedent): the three shard test files' own logic runs in
~413ms total (356+30+27ms) with all 392 assertions passing. Instead,
src/frontmatter.cts grew from ~825 to 1496 lines (+671/-187) migrating to
the vendored YAML parser, proportionally growing the mutant count Stryker
generates for gsd-core/bin/lib/frontmatter.cjs. Stryker's command runner
bills the full 'node --test <3 files>' invocation once per mutant, and
node:test's default per-file process isolation forks a child process for
each of the three files on every one of those invocations — pure fork
overhead multiplied by a much larger mutant population.

Fix: scripts/mutation-matrix.cjs COVERED.frontmatter now declares
isolation: 'none', and .github/workflows/mutation.yml passes
--test-isolation=${{ matrix.isolation }} (defaulting to 'process' — i.e.
unchanged behavior — for the other 8 shards, which were not individually
audited for cross-file state leakage under shared-process execution).
Measured locally via node:test's run() API on the exact 3-file set:
isolation:'process' took ~593ms vs isolation:'none' ~478ms for the same
392 passing assertions. The true CI-shard number can only be confirmed
on the GitHub Actions run (Stryker cannot run locally, and 'node --test'
is hard-blocked in this environment).

Refs #3881

* test(#3881): register the vendored-parser tests in the frontmatter mutation shard

stryker.config.mjs's own rule ("Keep this list in sync with the tests
arrays in scripts/mutation-matrix.cjs COVERED") was violated: #3881 grew
src/frontmatter.cts from ~825 to 1496 lines but its new tests
(tests/feat-3881-yaml-parser-consequences.test.cjs,
tests/frontmatter-golden-parity.test.cjs,
tests/frontmatter-roundtrip.property.test.cjs, and +167 lines in
tests/frontmatter.test.cjs) were never added to the frontmatter shard's
tests array, so Stryker's mutants in the new vendored-js-yaml adapter had
nothing constraining them. PR #3888 measured 55.8% against the 65 floor
(748 killed / 593 survived / 17 timeout) and the shard was separately
cancelled at 15m04s against the 15-minute per-shard cap.

Registers all four files (each earns its slot on evidence of a unique
constraining assertion, documented inline), gives the shard a
measured/projected 180-minute budget via a new per-module
timeoutMinutes field threaded through mutation.yml's job-level
timeout-minutes the same way isolation is threaded, and removes the
prior isolation:'none' override (re-measured at this file-set size, its
savings are within run-to-run noise, not worth the unaudited
cross-file-state-leakage risk).

near-miss: frontmatterDeepEqual's array-order/length/type-mismatch/key-order

leading/trailing-whitespace and dash/surrogate triggers (via reconstructFrontmatter),

Add an injectable --matrix seam to scripts/check-mutation-score-ratchet.cjs and point the CLI rows at a synthetic module + synthetic floor built via a temp fixture, so the rows are indifferent to any real module's floor moving while still exercising the same fail/pass behaviour.

Restores the function plus its post-throw fallback path (loadWithAmbiguousColonRepair) only; repairMalformedInlineArrays and splitLegacyInlineArrayItems stay deleted, reverified against the full frontmatter test shard. Adds a frontmatter-level regression row in tests/feat-3881-yaml-parser-consequences.test.cjs so the dependency is visible where the function lives.

ddde001af6 enhance(#3873): the STATE.md schema — one owner, generated artifacts (#3880)
* test(#3873): failing-first locale parity, plus tripwires for what must not move

Pins ADR-3473 §8.8 at the artifact a reader actually sees. The English STATE.md
reference carries a Status lifecycle section that is missing from all four
translations — the section documenting the status enum whose clobbering is
#3853. The test derives the heading set rather than hard-coding the missing
one, and names the locale and the heading when it fails.

Two tripwires that must pass today and after. The field-drift guard still
catches a re-derived fallback ladder: §8.8 instructs deleting that script, and
that instruction rests on a wrong premise about what it guards, so the test
stops a future reader from deleting it on the ADR's word. And last_activity's
label resolution is pinned to what ships today, because it is declared in one
of the two tables this phase consolidates and not the other — the
consolidation must not silently pick a side.

The locale test buckets under docs rather than state, which is what it tests;
that bucket is allowlisted with justification rather than folded into an
unrelated docs suite. It reads only markdown, so it carries no allow-test-rule
marker — a marker there would suppress nothing and would grow the unverified
pool against its ceiling.

Refs #3873

* feat(#3873): one schema owns the STATE.md key set, three tables become projections

ADR-3473 §8.8. The key set was declared in four places that had to agree by
hand and already did not: FIELD_CLASSIFICATION, FRONTMATTER_BODY_SOURCE,
FRONTMATTER_KEY_TO_BODY_LABEL and buildStateFrontmatter's emit behavior. One
frozen null-prototype schema now declares each key's type, enum, cardinality,
source, preservation, body source, body label, accepted parse shapes and
whether it is emitted unconditionally; the three tables are derived from it at
module load.

The projections are byte-identical to the literals they replace, key order
included, and the parity tests compare against verbatim copies of today's
tables rather than re-deriving both sides from the schema — a parity test fed
from one source proves nothing, which is how a consolidation ships a changed
policy under a green test.

last_activity was the live disagreement: present in one table, absent from the
other. The schema declares what ships today rather than the tidier answer, and
a test pins it.

The schema is a leaf module and owns the four field-policy types, re-exported
from state-transition so existing importers are untouched — the same split
health-diagnostic-types made to break a CJS require cycle.

Refs #3873

* feat(#3873): generate the schema-derived regions, parity-check the prose tables

ADR-3473 §8.8's generator half. gen-state-md-docs.cjs owns marked regions in
the shipped template and all five reference docs, follows gen-features.cjs's
fail-closed contract, and is wired into regen:derived and lint:generated-sync.

The Status lifecycle section was missing from all four translations — the
section documenting the status enum behind #3853 — and is now generated into
every locale. Field cardinality is a new generated table: pure schema data,
no prose, so nothing to lose.

The Field-reference and Status-values tables are parity-CHECKED rather than
generated. Their Purpose, When-populated and Matched-text columns are
genuinely hand-translated per locale, and §8.8 itself says prose stays
hand-translated; generating them from an English registry would overwrite four
locales' translations on every write. The row set is checked against the schema
instead, so a key added to one and not the other fails, which is what field
drift actually means. Building that check found last_activity_desc
undocumented in all five tables.

Three keys the docs describe are absent from the schema — active_phase,
next_action, next_phases. They are grandfathered by name, not by wildcard, so a
fourth fails: a declared gap with a forcing function rather than a silent one.

Refs #3873

* fix(#3873): declare what the parsers do, and close the shape-parity gap

Two declarations in the new schema described intended behavior rather than
actual — the defect class this epic exists to end, committed inside the epic.
Both were caught by executing the parsers instead of reading their docstrings.

current_plan.acceptedShapes claimed ['N', 'N of M']. Standalone, the hybrid
shape errors; the path that looks like support is parseInt truncating '2 of 5'
to 2 and discarding the rest. Narrowed to ['N']. The parser is deliberately NOT
fixed here: that is #3784 and PR #3791 is already doing it. When #3791 lands
this row must widen, and the shape test will go red until it does — the schema
and the parser cannot drift apart quietly, which is what §8.8's checked-not-
generated rule is for.

STATUS_LIFECYCLE_ENUM claimed to be the closed set status can hold.
normalizeStateStatus passes unrecognized prose through unchanged, so it is not
closed at runtime. The seven members are the canonical values it maps onto; the
docstring now says that and the test asserts the real lenient contract.

Closes the acceptance item that a test asserts the parsers accept exactly the
declared shapes: the check is table-driven over every row carrying
acceptedShapes, guarded against passing vacuously on an empty set, and fails
loudly if a future row has no registered driver. Adds the unwired-label throw
and the fast-check property that every projection agrees with its schema row.

Refs #3873

* fix(#3873): keep the shipped template's frontmatter first, and make row 27 able to fail

The remote matrix caught 12 failures with one cause. Making the template's
frontmatter a generated region wrapped it in its own yaml fence ahead of the
markdown fence, so extractFileTemplate and readShippedStateTemplateBody — which
both match the single markdown block — found the heading first, not the
frontmatter. That breaks the contract every new project's STATE.md is created
from: bug #21 and epic #1969 B8 pin that the File Template block starts with
frontmatter and carries gsd_state_version.

The markers now sit inside the single markdown fence, so the fence opens before
the frontmatter and the region still ends ahead of the heading. Same layout as
before this phase, with markers embedded rather than a second fence.

Row 27 existed to catch exactly this and did not, because it was writer-seeded:
it asserted against the generator's own output shape, so it passed on the broken
template. It now parses the fence the way production does and was verified to
fail against the broken shape before being trusted against the fixed one. A test
that would not have caught the bug it exists to prevent is worse than no test.

The emitted-attribution failure was separate and the fragment was the wrong
remedy: gsd-core/templates/state.md self-attributes under a verbatim-copy
identity rule, so a diff touching it needs no acknowledgment. Fragment deleted
rather than left explaining nothing.

Refs #3873

* docs(#3873): how to change the STATE.md schema

The phase gate was right and my docs artifact was wrong. I listed
lint:generated-sync as the second enablement step, which is a verification
command dressed as one, and then claimed a one-step sequence owed no how-to.

The real sequence is build:lib then regen:derived, and the ordering is a trap:
the generator reads the COMPILED schema, so regenerating before building
regenerates against the previous schema and commits artifacts that look
plausible while disagreeing with the code just written. A reference table
cannot carry an ordering dependency; that is what the how-to test is for.

The page covers adding, changing and removing a key, every reason code the
check emits and what to do about each, what is generated versus hand-translated
and why the two prose-bearing tables are parity-checked instead of generated,
adding a language, and the three grandfathered keys. Indexed from docs/README.md.

1863f5569c enhance(#3871): the state transaction — mandatory snapshot, open()/rebuild() (#3874)
* test(#3871): failing-first regressions for the dropped curated progress block

Pins ADR-3473 §8.6 / #3756 at the consumer's output: state record-session and
state add-decision on an archived-milestone project drop the curated progress
frontmatter entirely, exit 0, and report nothing. Reproduced against the real
CLI before writing the tests, not inferred from the issue text.

Also adds the unit-level probe that applyStatePreservation's preserve-always
row is inert on a resyncing write, and an over-preservation guard that an
empty project is never inflated.

Refs #3871

* feat(#3871): make the STATE.md pre-write snapshot mandatory via open()/rebuild()

ADR-3473 §8.6. StatePreservationInput's nullable preFm and the always-present
preFmSnapshot were the same extractFrontmatter call, one of them nulled on
resync — a policy flag baked into a snapshot. Both collapse into a single
StateTransaction whose snapshot cannot be absent: openStateTransaction()
applies preservation, rebuildStateTransaction() does not, and both carry the
snapshot because the reporting phase needs it either way. An absent snapshot
is now a construction failure; an empty one stays legal, because that is what
a document with no parseable frontmatter honestly has.

writeStateMd requires a rebuild transaction, which types ADR-3408 §8.3's
closed exception list at both call sites (state sync, health --repair) instead
of matching them as strings in a ratcheted baseline.

Fixes the dropped curated progress block: an all-zero or absent derived total
set is an unmeasured scan, not a measurement, so the curated block stands.
Also fixes two defects surfaced while building — preserve-always reported a
mutation even when it restored an identical value, and it re-entered the
curated object by reference, which would alias the snapshot the next phase
diffs against.

Refs #3871

* fix(#3871): close the three remaining subsumed defects and restore the arm the type does not replace

Review of the first two commits found four things.

The guard shrink deleted the seam-bypass axis whole, but only its
writeStateMd( arm became redundant. Its other arm catches a call site
re-assembling syncStateFrontmatter + applyPostSyncPreservation instead of the
owned composition, which the transaction type does not make unrepresentable
and which #3469 found live. Restored as findCompositionBypasses, terminal
rather than ratcheted.

Three of the four issues this phase claims were untouched. All three are the
epic's own shape and are fixed at the seam: current_phase_name is reasserted
from the curated value when the caller names none, and cmdStateJson stops
carrying a hand-maintained list parallel to FIELD_CLASSIFICATION and projects
it instead.

The construction failure that is the point of this phase had no test. Every
enumerated matrix row now has one, including the measured-versus-unmeasured
coercion boundary and a seeded property that no curated key is ever dropped.

ADR-3473 §8.6 said the guard 'keeps only its raw-write check'. Verified
against next: there was no raw-write check, and four other checks it does not
name. Amended in place with the evidence. ARCHITECTURE.md separately
advertised a preservation policy the code had deleted.

Refs #3871

* fix(#3871): do not let the unmeasured-scan rule block an explicitly-requested resync

The remote matrix caught over-preservation, the failure this phase's own
negative space says must not happen. state update Progress re-derives the
block from the body the caller just rewrote; on a project with no phase dirs
the derivation yields zero totals, the unmeasured rule read that as 'the scan
measured nothing', and the stale curated percent was restored over the resync
the user asked for.

preserve-always already said what the missing condition was: never overwrite
unless the caller explicitly names this field. explicitProgressField carries
it and is derived from shouldResyncStateProgress, not set by hand at a call
site, so it cannot drift from what the caller asked for.

Two defects found in the same mechanism and fixed with it. readModifyWriteStateMd
enumerates its option keys, so a new option was silently dropped rather than
rejected. And the raw-write axis captured its first argument up to the first
comma, which lands inside a nested path.join, so a write to a STATE.md literal
was invisible to it — the prove-it-can-fail test caught that one immediately.

No test assertion was weakened; all three frontmatter rows encode #3242, #1969
B3 and #1972 and stand unchanged.

Refs #3871

* docs(#3871): record why the raw-write check is kept, not why it was named

The amendment justified findRawStateWrites as 'written because §8.6 requires
it to exist', which is cargo-culting the contract and would have been the
wrong reason to keep anything. The real reason is that writeStateMd acquires
the STATE.md lockfile and a raw fs.writeFileSync acquires nothing, so this is
a lock bypass and lost-update is the #500/#905/#1230 family — and after this
phase it is the one reachable path into the file that nothing else covers.

Also records why ADR-3408 §8.6's deletion of the 'clear' policy is not the
precedent it looks like: 'clear' was dead vocabulary in a closed enum, this is
coverage of a reachable path.

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

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

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

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

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

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

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

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

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

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

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

Three walls matter more than the new coverage:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Implements ADR-3408 section 8.3 as amended.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two spec-review gaps, both real.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

1218d76d62 refactor(#3468): dispatch state preservation on the declared policy, not the field (#3495)
* test(#3468): add write-path drift guard, ratcheted at its measured baseline

Guard-first, per ADR-3180 Amendment 3's standing rule that a phase builds
and runs its guard BEFORE its scope is fixed, and states its copy count as
'N found by the guard', never 'N per the epic'.

Measured, not assumed:

  Axis 1 (policy dispatch, ADR-3408 section 8.1) — 7 violations, RED by
  design. 5 field-name-keyed getFieldClassification('literal') branches
  plus 2 declared FieldPreservation members with no executor at all
  (derive, clear). This is the fail-first evidence for the refactor.

  Axis 2 (write seam, section 8.3) — 4 bypasses, ratcheted. Epic #3408
  scoped this at two writers; the whole-repo scan found four, and one the
  epic named (patchCore) is not among them because it bypasses via
  stateReplaceField rather than the seam calls. Fourth consecutive time an
  epic's copy count proved a lower bound.

Two detectors were written and removed again before this commit, both
recorded in the file header rather than silently dropped:

  - A prompt-layer detector that reported 5 backticked prose mentions as
    drift. That is ADR-3180 Amendment 3's recorded false-positive class,
    and CONTRIBUTING.md already settles it: a backticked command reference
    is a mention. Now gated on inline-code spans.

  - A stateReplaceField co-occurrence detector for section 8.3(b). Measured
    at 29 false positives to 1 true positive — it matched the function's own
    definition and ~20 calls on frontmatter-free body slices. Banking 29
    non-defects to catch one is the 'ratchet as a parking lot' gaming route
    Decision 5 names, so it is a DECLARED KNOWN GAP owned by Phase 2
    (#3469), which both fixes it and makes its detection tractable.

* test(#3468): failing-first coverage for policy dispatch and the loud failure

Matrix sections A, B and C from 50-test-matrix.md.

Expected RED against this tree, confirmed by static trace rather than
assumed:

  B1, B2, B3 — an unwired declared preserve-when-unchanged row must throw
  with code STATE_PRESERVATION_UNWIRED_ROW and a structured .field. Today
  src/state-transition.cts:314 silently continues.

  A4 — a whitespace-only snapshot is restored today, because the guard is
  .length > 0. Required behavior is skip.

Everything else is characterization, locking in behavior the refactor must
preserve. C1 is table-driven over every FIELD_CLASSIFICATION key; C2 pins
current_phase_name's exact outputs as literals, because its row is being
reclassified preserve-always to preserve-when-unchanged as a
behavior-preserving change and nothing else would catch a drift. C3 is a
seeded fast-check property (seed 3468, 200 runs, replay data on failure).

A22 is deliberately NOT a behavioral test. Whether 'derive' has an explicit
executor is not observable through applyStatePreservation's public API — it
is a structural property, and the drift guard's unimplemented_policy axis is
what enforces it. That split is ADR-3408 Decision 5's own pairing: the lint
is the structural metric, the test is the outcome metric, and neither is
reported alone.

* refactor(#3468): dispatch preservation on the declared policy, not the field

Implements ADR-3408 sections 8.1, 8.2 and 8.6.

applyStatePreservation is now one loop over FIELD_CLASSIFICATION dispatching
on the row's preservation value, with four small executors — one per
FieldPreservation member. No branch is selected by field name. Zero
literal-argument getFieldClassification calls remain.

Behavior-preserving for 16 of 20 input classes. The four that change:

  - An unwired declared preserve-when-unchanged row now THROWS
    (code STATE_PRESERVATION_UNWIRED_ROW, structured .field) instead of
    silently continuing. This fires only on an internal invariant violation
    with both ends in our own source; a drifted, malformed or unparseable
    user STATE.md must never reach it, which is section 8.2's bright line
    and what test B8 proves through the real CLI.
  - derive gained an explicit no-op executor. That is what makes the throw
    decidable: 'policy says do nothing' is now distinguishable from 'nobody
    wired this'.
  - current_phase_name's row is corrected from preserve-always to
    preserve-when-unchanged. The row was wrong, not the code — it has always
    been delta-gated on the body Phase line, so preserve-always had two
    divergent implementations. Behavior is unchanged and test C2 pins it.
  - A whitespace-only snapshot is no longer restored; the check is trimmed.

clear is deleted from the FieldPreservation union — no row used it and no
executor existed. Speculative Generality: a policy invented for a need that
never arrived. Verified zero dependents.

The caller folds six dedicated pre/post parameters into one bodyDeltas map
keyed by field, so all seven preserve-when-unchanged rows travel one channel
instead of two. Two shapes for one kind of data is why the executor needed
per-field branches at all.

Also fixed, found while reviewing the refactor rather than deferred:

  - applyPreserveIfPlaceholder opened with a field-name literal test, which
    section 8.1 forbids outright. The executor is idempotent, so the test
    bought nothing. The drift guard could not see it, so Axis 1 is widened
    to catch field-variable comparisons against literals — the guard
    reported zero while a violation sat in the file it polices, which is
    Goodhart's gaming-by-indirection.
  - loadBaseline conflated an unreadable baseline with an absent one. A
    guard whose own diagnostic collapses two states into one identical
    result reproduces the exact failure shape this epic exists to remove.

* docs(#3468): record Phase 1 validation as ADR-3408 Amendment 1

Amendment 1 records what Phase 1 found, per ADR-3408 section 8's rule that a
behavior it does not state is not decided:

- preserve-always had TWO divergent implementations; current_phase_name's
  row was wrong and is reclassified, behavior unchanged.
- section 8.6 resolved: clear is deleted, zero dependents.
- the closed guard vocabulary is real and has exactly one true member,
  because stopped_at's scoping turned out to be caller-side extraction.
- copy count found by the guard: 4 write-seam bypasses where the epic
  scoped 2, and patchCore — one of the two it named — is not among them.
- two detectors built and removed again, with their measured false-positive
  rates, so nobody re-attempts them.
- a DECLARED KNOWN GAP for section 8.3(b), owned by Phase 2.
- Decision 5's anti-gaming list earned itself twice in one phase.

Also adds the changeset fragment.

* test(#3468): fix review findings — try/finally, stale clear allowlist, ratchet owners

Standards axis, both hard violations:

  - tests/state-write-path-drift-guard.test.cjs wrapped stdout/argv/exitCode
    restoration in try/finally inside the test body. CONTRIBUTING.md:356
    forbids it outright, and the correct t.after() pattern was already in
    use two lines up in the same test.

  - tests/state-transition.test.cjs still listed 'clear' as an allowed
    FieldPreservation value in the row-enumeration test AND the
    getFieldClassification property test, after this PR deleted it. A stale
    allowlist weakens the property's negative space — it would accept a
    resurrected clear row as valid.

Contract tension, resolved rather than left:

  ADR-3408 section 8.3 requires each ratchet entry carry the issue owning
  its removal. All four shipped with owner: null. The guard was right not to
  INVENT one, but the owners are known from the phase plan, so recording
  them is not inventing: phase.cts -> #3469, state.cts and milestone.cts ->
  #3471, health-diagnostic.cts -> sanctioned-permanent.

  Rather than a JSDoc caveat, --baseline now MERGES prior owner values on
  the (file, source) key, so a mechanical regeneration can no longer
  silently discard curated provenance. Verified by regenerating twice.

* fix(#3468): sanitize attacker-controlled fields on every guard output path

Isolated security review, MEDIUM, confidence 8/10.

findSeamBypasses and findPromptSeamUses built findings with an UNSANITIZED
`file`, while the co-located `source` on the same object was correctly
wrapped in sanitizeForReport. On a fork PR a filename is exactly as
attacker-controlled as a source fragment — a repo can legally track a
filename carrying C1 control bytes or bidi overrides.

The raw value reached two paths: --json stdout, and the COMMITTED baseline
JSON via buildBaselineEntries. JSON.stringify neutralizes C0 controls but
does NOT escape C1 (0x7f-0x9f) nor the bidi/zero-width range
sanitizeForReport exists to strip — which is the precise threat the guard's
own header names. Only the human formatter was safe.

Sanitization now happens at CONSTRUCTION, so every consumer inherits it
rather than each output path having to remember. The same defect was present
on `field` and `policy` and is fixed alongside. Double-sanitization in the
formatter is left in place, verified idempotent: escaped output is ASCII and
cannot re-match the control/bidi classes.

Also: the guard was not referenced anywhere in package.json, so nothing ran
it. A drift guard nobody runs is not a guard, and ADR-3408 Decision 5 assumes
it runs. Wired into lint:ci beside its sibling drift guards; it was already
green on this tree, so the chain stays green.

* chore(#3468): re-curate ratchet after an upstream rewording of a tracked bypass

The rebase onto origin/next turned the guard red on its first real day, which
is the ratchet working rather than a defect.

c90ae479f fix(#3350) reworded cmdPhaseComplete's syncStateFrontmatter call
onto one line and changed its third argument. Because entries are keyed on
(file, trimmed source text) rather than a line number, that single upstream
edit registered as BOTH a stale acknowledgment and an unrecorded site — the
two-sided signal the design intends, forcing a human to look rather than
letting a tracked bypass drift out of view.

The owner-preserving merge behaved exactly as designed: three owners survived
because their keys were unchanged, and phase.cts's dropped to null because its
source text is genuinely a different key. Re-curated to #3469, the phase that
owns its removal.

Note for Phase 2: c90ae479f is #3350's fix landing independently on next —
one of the two instances Phase 2 was scoped to drive fail-first. Surfaced to
the epic rather than absorbed silently.

* test(#3468): derive B1's fixture from the table so it cannot go stale

Checkpoint 2 came back with 2 failures of 33803, both B1:

  actual   'current_phase_name'
  expected 'current_plan'

The implementation was right and the test was stale. B1 hand-built a
bodyDeltas literal intending current_plan to be the ONLY unwired row, but it
also omitted status, stopped_at and current_phase_name — all three of which
became preserve-when-unchanged rows in THIS PR. Table order puts
current_phase_name first, so the throw correctly named it.

B1 now builds from neutralBodyDeltas() and deletes exactly one key, which is
what its own comment always claimed it did. A future table change can no
longer silently make it assert the wrong field.

Audited every other bodyDeltas literal in the file: four exist, all correct —
two enumerate all seven rows explicitly, two pass {} where the emptiness is
the point of the test. Roughly thirty other sites already derive from the
helper.

Also renames the local unchchangedChanged to lastActivityDescChangedDeltas.
A typo'd identifier that happens to work is still a Mysterious Name; noted
during research and fixed now that this change touches the file.

* chore(#3468): re-curate ratchet and fold the seam channel into the shared helper

The rebase onto be9329b10 fix(#3374) was a true semantic conflict, resolved
rather than handed back, because the resolution was determinable:

That PR extracted the post-sync preservation pass into a shared
applyPostSyncPreservation helper — which is ADR-3408 section 8.3, i.e. a
piece of Phase 2's own deliverable, landing upstream. Its structure is kept
wholesale; this branch's contribution is applied INSIDE it.

That combination had to be checked rather than assumed. Upstream's helper
wires only FOUR bodyDeltas keys and still passes status / stopped_at /
current_phase_name through six dedicated parameters. This branch reclassifies
current_phase_name to preserve-when-unchanged, deletes those six parameters
from StatePreservationInput, and makes an unwired declared row THROW. Taking
upstream's file as-is would therefore have thrown on EVERY STATE.md write.

The helper now wires all seven rows through the single channel. Verified
7-to-7 against FIELD_CLASSIFICATION, with a clean tsc — which is the real
proof the dedicated parameters are gone, since they no longer exist on the
input type.

The ratchet also caught the same phase.cts call being reworded a second time,
reporting it as both a stale acknowledgment and an unrecorded site. Re-curated
to #3469. Recording the tradeoff plainly: keying on (file, source text) means
an upstream reword of a tracked line needs re-curation, where keying on line
numbers would churn on every unrelated edit. ADR-3180 Decision 4(e) chose
source text deliberately, and the owner-preserving merge added earlier covers
the common case where the text is unchanged.

be9329b10b fix(#3374): phase.complete stops harvesting stale body stopped_at (#3491)
* fix(#3374): phase.complete stops harvesting stale body stopped_at

Variant A: cmdPhaseComplete's adapter calls syncStateFrontmatter directly
(deliberately - STATE.md commits atomically with ROADMAP/REQUIREMENTS),
which also bypassed the #948/#1230 preservation pass every RMW write gets.
A stale body 'Stopped at:' line then silently clobbered a fresher
frontmatter stopped_at on every phase completion, with warnings: [].

Three layers close it without reversing #3517's refresh expectation:
- completePhaseCore now refreshes the body continuity line it implies
  ('Phase N complete, ready to plan Phase N+1'; ADR-2207 phrasing on the
  last phase), session-scoped via the new stateReplaceFieldInSession seam
  so a decoy bold Stopped-at line in an unrelated section cannot absorb
  the refresh. Replace-only - a layout with no session line keeps its
  shape and its frontmatter value survives via the preservation delta.
- the RMW post-sync preservation chunk (snapshots + table-driven
  applyStatePreservation + #2736 re-assert, full bodyDeltas wired) is
  extracted into the shared applyPostSyncPreservation helper; the
  phase.complete adapter and writeStateMd (milestone complete / state
  sync - the gap the closed PR #3442 review flagged) now run it too.
- cmdStateRecordSession pushed 'Stopped At' onto updated[] on any label
  MATCH, including a value already on disk - reporting a write that never
  changed a byte. It now reports only on real change, and the match is
  tracked separately so an identical value does not arm the #944 DWIM
  section rewrite (which would reset an executor-authored resume file to
  None).

* docs(#3374): backfill changeset pr field to 3491

* fix(#3374): drop the writeStateMd preservation pass - state sync's #905 contract is body-wins

CI on this PR caught what the closed PR #3442 review's MAJOR remediation
option (a) would have broken: state sync's #905 contract ('body annotation
beats existing frontmatter when both are present') is the opposite by
design - sync exists to re-derive frontmatter from the body. A blanket
applyStatePreservation pass on writeStateMd re-locked stale frontmatter
(current_phase 3 over the body's 5) on every sync.

Take the review's sanctioned option (b) instead: the scope claim is
accurate (phase.complete only) and the milestone complete / state sync
exposure is tracked as follow-up issue #3492.

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.

e87fb409ee enhance(#2573): stamp STATE.md with its commit and surface a freshness hint (#2622)
* enhance(#2573): stamp STATE.md with its commit and surface a commit-age freshness hint

Adds a `state_head` stamp to STATE.md and derives a tri-state commit-age
freshness proxy (state_commits_behind / state_commit_stale) through
state.cjs's readStateHeadFreshness, surfaced on smart-entry signals and as
health W024. The proxy is advisory: classify() deliberately does NOT consume
it (ADR-1787 locks the classification/routing boundary — a signal, not a route).

Composes with #3099 and #1882 (both merged to next after this branch): the
commit-age proxy reads `state_head` while the LAST_ACTIVITY_UNPARSEABLE
diagnostic reads `last_activity` — two different fields, not "two staleness
signals on one field." A new regression test asserts a STATE.md carrying both
an unparseable last_activity AND a valid state_head resolves each independently
(diagnostic fires once; freshness reads state_head, commits_behind 0).

Rebased onto next (flattened): resolved the add/add conflicts in
src/smart-entry.cts (kept both the #2573 freshness import/derivation and the
#3099 diagnostic import/call) and tests/smart-entry.unit.test.cjs (kept both
describe blocks). Drift-ack for health.md's W024 row is unchanged (12348 B).
Tests: smart-entry 62, state/state-transition/health/verify 639, all pass.

* chore(#2573): allowlist health-validation test in the prompt-injection scan

The scanner's `exec('` code-execution pattern matches the benign
`re.exec('<phase-id>')` RegExp method calls in the phase-ID grammar tests
(pre-existing: 16 such calls on next, this PR adds none). The file entered the
diff-mode scan's changed-file set only because #2573's W024 state_head
assertions touch it. Allowlist it alongside the other test files that carry
pattern-matching content as data (same DEFECT.PROMPT-INJECTION-SCAN-COLLISION
class). Scanner self-test 38/0; diff scan 14 files, 0 findings.

0e6fa2e2cf enhance(#3118): close the dead injectables and the shell projection follow-on — Wave 4 (#3124)
* test(#3118): failing-first coverage for the dead injectables and the shell projection

Adds the counter-tests Wave 4 closes against, before any fix:

- antigravityWatermark had zero test references. The four existing tests
  that look like watermark coverage hand the fallback a literal mark and
  never call the producer, so nothing pinned whether a real run's mark is
  correct. Covers all six branches plus the non-object cache classes.
- Pins the fail-open: a transcript read that throws reports lines:0,
  indistinguishable from a genuinely empty transcript, and the consumer
  then replays a previous run's review as this run's.
- Pins the export-line escaping across the repair, persist and win32 bash
  lanes, including the parity assertion that they must not diverge.
- sliceCurrentPositionSection: empty-vs-absent, fenced heading, second
  occurrence, H3, CRLF.
- Proves deps.progressProvider is inert by supplying a throwing stub to
  all ten transition intents.

Verification through the remote runner only.

Refs #3118

* fix(#3118): distinguish an unreadable transcript from an empty one

antigravityWatermark's final read can throw on a transcript that
indisputably exists. It returned lines:0, which is the same value a
genuinely empty transcript produces, so the caller could not tell the
two apart.

antigravityTranscriptFallback derives its skip from that count. A mark
of {convId:'c1', lines:0} for a conversation that pre-dates the run
makes it skip nothing and return the last PLANNER_RESPONSE in a
transcript written before this run started — a previous review
presented as this one's, which is exactly what the function's own
'never stale' docstring promises cannot happen.

The unreadable case now sets unreadable:true and the fallback declines
for a same-conv-id unreadable mark. An absent or empty transcript is
untouched: those genuinely have zero prior lines.

* fix(#3118): escape the export line for the file it lands in, not the echo

Three lanes emit export PATH="<dir>:$PATH". repair escaped it with
escapePosixDoubleQuoted; persist and the win32 Git Bash lane escaped it
with escapeSingleQuotedShellLiteral instead.

The single-quoting is correct for the echo, so nothing runs when the
user pastes the command. But the bytes appended to ~/.bashrc are the
export line itself, and inside double quotes in an rc file a $(...) or
a backtick in the directory name is command substitution that runs on
every new shell. Those characters are legal in a path on both POSIX and
Windows, so the path was reachable.

projectPathExportLine is now the single source of that line and escapes
for its final rc-file context; each lane still applies its own transport
escaping on top. fish keeps the single-quote escaper — its value really
does stay single-quoted.

The cmd.exe lane interpolated into a cmd double-quoted string with no
cmd-level escaping, so a quote closed the region and &cmd& ran. A quote
is reserved on Windows and cannot appear in a real path, so there is no
correct command to suggest: the win32 lanes now fail closed for one.

Metacharacter-free paths render byte-identically on every lane.

* fix(#3118): drop a stray carriage return and a deps field nobody reads

locateCurrentPosition subtracted a fixed one byte to exclude the newline
before the next heading, which assumes LF. On a CRLF document the slice
kept an unpaired trailing carriage return. It now walks back over the
newline and over a preceding carriage return if there is one.

StateTransitionDeps also required a progressProvider that 33 sites
supplied and no site ever called. A required field nothing reads widens
the module's interface without changing its implementation, which is the
shape epic #3051 cites as its reason for refusing blanket injection.
Removed along with the ProgressRecord alias that existed only as its
return type; state-document.cts's unrelated interface of the same name
is untouched.

* fix(#3118): stop an empty span duplicating bytes, and name the empty results

Three findings from the isolated review pass.

locateCurrentPosition could return end < start when the section was
empty and the next heading followed with no blank line between. Every
mutator splices with slice(0,start) + body + slice(end), so an inverted
span duplicated the region between them — a blank line silently
inserted into STATE.md on every transition, two bytes on CRLF. The span
is now clamped, and an empty section is a zero-length span, which is
what it always meant.

The win32 fail-closed path left the installer printing 'Add it with one
of:' with nothing under it. An empty shellActions folded two different
facts together, so projectPathActionProjection now carries a frozen
PATH_ACTION_REASON and the installer branches on it. Two empty results
with different causes staying distinguishable is the subject of the
epic this belongs to.

fish_add_path parses a leading dash as an option, so a directory named
-v printed 'No paths to add' instead of being added. Verified against
fish 4.8.1: the end-of-options separator fixes it.

Replaces the console-prose test the second fix first arrived with — a
regex over captured stdout is what CONTRIBUTING prohibits, and the
typed reason is the surface it asks for instead.

* fix(#3118): escape TOML control characters, and stop a test name overstating

Five findings from the two review axes.

escapeTomlDoubleQuotedString escaped only backslash and quote. TOML
basic strings also require U+0000-U+0008, U+000A-U+001F and U+007F to be
escaped, so a value carrying a raw newline or NUL wrote a config.toml no
parser accepts — rejecting the whole file, not just that value. Four of
its call sites write real config. Tab stays raw; the grammar exempts it.

The byte-identity test claimed every lane was unchanged for an ordinary
path, which is false: fish now takes the end-of-options separator on
every path, not only hostile ones. Renamed, and the one intended delta
now has its own named test instead of hiding inside a claim that read
as broader than it was.

Also: exact-equality assertions in place of substring checks that could
pass on a subtly wrong escape, newline and null-byte cases for all five
quoting primitives, and a temp dir registered with t.after so it is
removed when an assertion fails.

* docs(#3118): add the changeset fragments

* fix(#3118): degrade instead of throwing on a null conversation cache

A cache file whose whole content is the literal null — what a truncated
or zeroed write leaves behind — made both antigravityWatermark and
antigravityTranscriptFallback throw. JSON.parse('null') succeeds, so the
try/catch wrapping the parse never fired, and resolveConvId then called
hasOwnProperty on null.

Both functions advertise the opposite; the existing test next to them is
named 'a missing cache or transcript degrades to empty, never throws'.
Parsing successfully is not the same fact as the payload being usable,
and a guard that only wraps the parse cannot tell them apart.

resolveConvId is now total for any non-object input, so one guard covers
both callers. Caught by the null case in this wave's own cache matrix.

* test(#3118): correct a stale fish expectation and a parity comparison

The pre-existing 'POSIX persist mode escapes single quotes' test pinned
fish_add_path without the end-of-options separator this wave adds, so it
asserted behavior that is no longer correct. A repo-wide scan found one
such hardcoded expectation; every other site derives its expectation
from the projection.

The new parity test compared the token from a POSIX path against the
win32 lane, which posix-normalizes its input first — two different
inputs, so the tokens differed for a reason that had nothing to do with
the parity it claims to check. It now derives the win32 expectation from
the same input the lane receives.

* docs(#3118): reword a comment the injection scanner reads as an instruction

The scanner pattern act\s+as\s+(?:a|an|the)\s+ carries no word
boundary, so 'the same fact as the payload' matched on the tail of
'fact'. Reworded per the documented remedy for this collision.

The missing boundary is a scanner defect rather than a prose problem —
any contributor writing 'fact as the' trips it — but the pattern is
gate plumbing, which the sibling epic owns, so it is surfaced rather
than changed here.

* chore(#3118): backfill changeset pr number to 3124

* chore(#3118): backfill changeset pr number to 3124

* fix(#2784): make the negation scan single-pass and index it correctly

Three defects in the negation suppression added by #3127, all in one
block, none of which had a test.

The pair scan was verbs.some(nouns.some(...)) with a slice and a split
per pair, so it grew cubically with clause length: 1.1ms before that PR
and 8462ms after, on 800 verb+noun pairs in one clause. api-coverage's
property test generates documents large enough to reach the runner's
600s file cap, which is why it hangs as 'fail 0, cancelled 1' rather
than failing an assertion. Every (verb, noun) window is a subset of the
single widest one, so one scan of that window answers the same question
in a linear pass. Verified equivalent against the old predicate over
20,000 generated clauses.

Both checks also subtracted clause.start from offsets that collectTerm-
Matches already returns clause-local. The first clause on a line has
start 0 so it worked there and nowhere else: later clauses went
negative, and slice reads a negative index from the end, so suppression
silently examined unrelated text.

The comment claimed 'without any API integration' was suppressed. It is
not — the qualifier sits outside the two-word lookback and the noun
precedes the verb. Widening the window would trade a false positive
that costs one declaration line for a false negative that slips a real
integration past a blocking gate, so the behavior stands and the
comment now says so. Pinned by a test.

The qualifier sets were also rebuilt for every line of every document.

b0f1722662 fix(#2969): ratchet completed_plans up for gap-closure plans under deriveProgressKeys (#3091)
* test(#2969): completed_plans must ratchet up for gap-closure plans

Failing-first regression: when deriveProgressKeys=true (cmdStatePlannedPhase's
opt-in), applyStatePreservation restores completed_plans to its pre-growth
curated value, so gap-closure plans that complete never increment it —
STATE.md shows completed_plans < total_plans forever even though every PLAN
has a SUMMARY. Three cases: the ratchet-up (derived 54 > curated 50), the
ratchet-down protection (derived 47 < curated 50 keeps curated), and the
body-only write protection (no deriveProgressKeys → wholesale restore).

The existing #2440 test covers the case where derived < curated (ratchet
holds); this adds the missing case where derived > curated (ratchet must
release upward).

* fix(#2969): ratchet completed_plans/plases up under deriveProgressKeys

applyStatePreservation's deriveProgressKeys path (cmdStatePlannedPhase's
opt-in) let total_plans/total_phases take the derived value but restored
completed_plans/completed_phases to their pre-growth curated value — so
gap-closure plans that completed after the plan count grew never incremented
them, leaving STATE.md at completed_plans < total_plans forever (every PLAN
had a SUMMARY).

Extend the deriveProgressKeys exclusion to also let completed_plans and
completed_phases take the derived value, but ratcheted UP only (never derive
downward past curated) — preserving the #3242 curated-progress protection
for cases unrelated to plan-count growth (e.g. a deleted SUMMARY). percent
takes the derived value (the resync already recomputed it from disk counts).

Scoped to deriveProgressKeys (plan-phase only); body-only writes
(state.update/patch without the flag) keep the full #3242 wholesale restore.

* fix(#2969): also take derived percent under deriveProgressKeys

Isolated-review blocker: percent fell into the else branch and was
overwritten with the stale curated value, contradicting the inline comment
and leaving STATE.md incoherent (e.g. completed_plans:54/total_plans:54 at

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.

* 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.

82ca13f5a5 fix(#2736): write current_phase_name from the transition intent, not the lossy prose round-trip (#2821)
* fix(#2736): intent-first current_phase_name on transitions; dash-first prose precedence

Primary: completePhase (adapter) and beginPhase (via readModifyWriteStateMd
options) pass the intent-held display name to syncStateFrontmatter as an
authoritative override, applied after every derive/preserve/carry-forward
step — so the lossy prose round-trip can never destroy a name the transition
just resolved. Names containing a parenthetical
(`Closer-ruling measurement (D1a)`) now land in frontmatter verbatim instead
of collapsing to the parenthetical (`D1a`).

Secondary (#1695 AC #3 residual): parsePhaseFromProse prefers the em-dash
name when it is a genuine name (not a status keyword, not a `Milestone:`
tail), else falls back to the parenthetical — satisfying both first-party
writer shapes (`N — Name (aside)` and `N (Name) — EXECUTING`). Still lossy
for paren-containing names, which is why the intent-first override is the
primary fix.

plannedPhase carries no name in its intent, so it is naturally out of scope.

9a76ca6783 fix(#1882): distinguish unterminated frontmatter from absent frontmatter (#2712)
* fix(#1882): distinguish unterminated frontmatter from absent frontmatter

extractFrontmatter returned {} both for a document with no frontmatter and for
one whose fence was opened and never closed, so a file truncated mid-write was
byte-identical to a legitimate no-metadata file. Verified live through
`gsd-tools frontmatter get`: both printed {} with exit 0 and nothing on stderr.

Per ADR-1411's "corrupt is not absent" amendment the {} return is preserved
exactly -- no caller may break -- and the cause is surfaced out-of-band as a
deduplicated, unconditional stderr diagnostic. That mechanism lands as a shared
leaf module rather than a per-site copy because three sibling findings in the
same epic need it identically; four hand-rolled copies of one behaviour is the
generative-fix-divergence defect class.

The discriminator is deliberately not "opened but never closed". A Markdown
document whose first line is a thematic break takes that exact branch, so
flagging on the missing fence alone reports corruption on good Markdown -- the
failure mode this class of check has shipped with before. The unterminated
region is instead run through extractFrontmatter's own parser (extracted as
parseYamlRegion so the probe and the real parse can never diverge) and reported
only when it yields at least one key.

Also folds an inline defect found while working: src/config-loader.cts carried
two NUL bytes in the JSDoc added by this epic's Phase 1 (3eb1cede2), making it
the only non-text file under src. file(1) reported it as data and text tools
silently skipped it, defeating the audit rule that says to search the authored
source; tsc passed because the bytes sat inside a comment, so no gate caught it.
It is live on next.

* test(#1882): pin unterminated-frontmatter detection and its negative space

Covers the discriminator on both sides. The positive rows are the issue's own
repro (LF and CRLF) plus the key-count boundary 0/1/2 around the ">= 1 parsed
key" threshold. The negative rows are the documents that reach the same branch
and must stay silent -- above all a Markdown thematic break at byte 0, which is
how this class of check has previously shipped a false positive on valid
Markdown.

Deduplication is tested on both halves of the composite key: a repeat of the
same (path, cause) is suppressed, a genuine second failure in a different file
is not, and a Windows and POSIX spelling of one path resolve to a single key.
The reset seam is asserted to actually clear -- #2674 is the precedent where a
reset that silently failed to clear made every later dedup assertion a vacuous
pass, and the cases only passed because each happened to pick an unused key, so
every case here uses a path unique to itself.

Assertions are on typed surfaces throughout -- the frozen reason enum and the
dedup-set size -- never on diagnostic prose. The one CLI-level case asserts a
differential between two runs (whether stderr is empty) rather than matching a
message, and is the wired user-reachable surface for this fix. Stream failure is
injected by overriding process.stderr.write and restoring it, never chmod 0o000,
which root bypasses.

Two properties guard the ~50 call sites of the changed function: the new
optional path argument is inert with respect to the parsed value, and LF/CRLF
spellings of a document still parse identically.

* fix(#1882): raise the truncation threshold and repair the dedup key

Isolated adversarial review found the one-key discriminator false-positives on
ordinary Markdown: a thematic break above a single labelled line -- `Note:`,
`Author:`, `TODO:`, `See:` -- parses as exactly one key and was reported as
corruption, which is the precise failure the design claimed to prevent and the
changeset promised was fixed. The threshold is now two keys. A file truncated
after exactly one key becomes a false negative; that is the same
precision-over-recall direction already taken at zero keys, and every GSD
artefact this guards carries two or more frontmatter keys.

Three dedup-key defects, each of which could silently swallow a real diagnostic:

- Backslash normalization is removed. A backslash is a legal filename character
  on Linux and macOS, so folding it to a forward slash made two genuinely
  different files share one key. Two spellings of one Windows path may now
  report twice; two distinct files can never silence each other. Lost signal is
  the worse failure.
- The key namespaces are tagged so a file literally named like the unnamed
  digest fallback can no longer collide with a path-less caller whose content
  hashes to that digest -- computable for any predictable content, no brute
  force needed.
- The source identity is computed once rather than hashed twice per emission.

Corrects the previous commit. The two NUL bytes in src/config-loader.cts were
NOT in a JSDoc comment as that message claimed; they were deliberate separators
in the live dedup key, and stripping them degraded it to bare concatenation.
They are restored as escape sequences -- byte-identical runtime string, and the
file is text again so grep can see it. The diagnostic script that misled me
indexed a character-offset string with a byte offset.

Also threads sourcePath through the STATE.md and PLAN.md readers so the two
artefacts epic #1879 is actually about name their file rather than reporting
under a content digest.

* test(#1882): correct fixtures and assertions left behind by the review fixes

The previous commit changed two behaviours deliberately and the suite still
encoded the old ones, so gsd-test came back red with six failures across both
lanes -- all of them mine.

Fixtures carrying a single frontmatter key no longer clear the two-key
truncation threshold, so the CLI differential and the two path-less dedup cases
were asserting a diagnostic that is now correctly withheld. They now carry two
keys, which is what a real interrupted write of a GSD artefact looks like.

The Windows/POSIX case asserted that two spellings of one path collapse to a
single key -- the exact folding that was removed because it also collapsed
genuinely distinct POSIX files whose names contain a backslash. Inverted to
assert they now report separately, with the reasoning recorded inline so the
trade is not silently reversed later: mild duplicate noise on one Windows path
is acceptable, a swallowed diagnostic is not.

Refs #1879

* fix(#1882): name the file at every read site, and report each file once

The diagnostic reached only the four frontmatter CLI verbs, so ~47 of 53 call
sites reported a truncated file under an anonymous content digest instead of
naming it. Since naming the file is the whole point -- it is what an operator
can act on -- that was a gap in the deliverable, not a scoping choice. 43 of 53
sites now pass the resolved path.

Closing it surfaced a defect the original design missed. A single truncated
STATE.md is parsed twice in a normal run: once by the read wrapper, which holds
the path, and again by a pure core downstream, which is handed only the string
and cannot know it. Those two parses keyed separately, so one file produced two
diagnostics -- and wiring more sites made the collision more likely, not less.
Every emission now registers both identities the input could be known by and
checks both before writing, so whichever caller arrives first speaks and the
other is suppressed. Distinct files with distinct content still report
separately, which is the property ADR-1411 actually requires; two files whose
truncated content is byte-identical collapse to one report, which stays the
documented limit.

Ten call sites deliberately keep no path. Two are frontmatter's own round-trip
checks during set and merge, where passing a path would report on every write.
The other eight are the state-transition pure cores, which ADR-1769 defines as
(content, intent, deps) -> newContent with injected I/O; threading a path
through them would contradict that recorded decision, so it is surfaced rather
than taken unilaterally. With the widened key they no longer double-report, and
in the normal flow the named parse runs first, so the file is still named.

Refs #1879

* fix(#1882): inject the STATE.md path into the transition cores

The six state-transition cores parsed STATE.md frontmatter without knowing
which file it came from, so a truncated STATE.md reached the operator as an
anonymous content digest on exactly the artefact epic #1879 is named for.

ADR-1769 section 3 shapes these as (content, intent, deps) -> newContent with
injected deps, and deps is the seam for precisely this: something the core
cannot derive without doing I/O. It already carries roadmapProvider and a
phase-inventory provider on that basis, each documented as injected rather than
imported so the core stays pure and testable without disk access. A resolved
path is data, not I/O, so an optional sourcePath member extends the established
pattern rather than contradicting it, and every existing stub keeps compiling
because the member is optional.

updateCore and reconcileCurrentPosition take no deps and are left alone. With
the widened dedup key they cannot double-report, and in the normal flow the read
wrapper has already named the file by the time they run.

Also regenerates gsd-core/bin/lib/state-transition.cjs. That artifact is tracked
rather than gitignored, unlike most of its siblings, so leaving it stale would
have shipped a runtime without this change to anyone reading the repo without
building. tsc had skipped the re-emit because its incremental build info still
recorded an emit that had since been reverted, so the stale output survived a
clean build; clearing tsconfig.build.tsbuildinfo forced it. The
compiled-artifact-sync gate is what surfaced the drift and now reports all nine
tracked artifacts matching their source.

* fix(#1882): stop the widened dedup key from hiding a second file

The previous commit widened the dedup guard so one file parsed twice -- once by
a read wrapper holding the path, once by a pure core holding only the string --
reported once instead of twice. It did that by checking BOTH keys before
emitting, which silently traded one defect for a worse one: two DIFFERENT files
whose truncated content happened to be byte-identical now collided on the shared
content digest, and the second file's diagnostic was swallowed. That is the
over-coarse keying ADR-1411 explicitly forbids, reintroduced while fixing
something else.

The guard now checks only the key matching what the caller actually knows -- a
named read checks its path key, a path-less read checks its digest key -- while
still recording every key the input could later be identified by. The redundant
path-less re-parse of an already-named file stays silent, and two distinct files
always both report.

Verified across all six orderings: same file named-then-anonymous reports once;
two different files with identical content report twice; two different files
with different content report twice; the same path twice reports once; two
path-less parses of identical content report once; two path-less parses of
different content report twice.

The suite caught this -- twenty failures, all in the unusable-input tests that
reuse one truncated fixture across different paths. The local probe written
alongside the broken change did not, because it compared two files with
different content and could therefore only confirm the expected behaviour.

Refs #1879

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

* test(#1882): count diagnostics emitted, not identities interned

The suite measured the size of the dedup set as a stand-in for "how many
diagnostics were emitted". That held only while one emission recorded exactly
one key. Once an emission began recording every identity the input could later
be matched by -- a path key and a content key for the same file -- the set grew
by two per write and twenty assertions read 2 where they expected 1.

The production behaviour was correct throughout; the proxy was not. Set size
counts identities, which is an implementation detail of the guard. The
behavioural claim these tests exist to make is how many diagnostics an operator
actually saw, so the module now exposes that directly as an emission counter and
the suite asserts on it. The set-size accessor stays for assertions genuinely
about key shape.

The local probe written alongside the change did not catch this because it
counted process.stderr.write calls -- the right thing -- while the suite counted
set growth. Verification now asserts both and requires them to agree, so a
future divergence between the counter and real writes fails immediately rather
than being discovered a bench run later.

* 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.

* fix(#2400): warn on planned-phase no-op + sync progress.total_plans

Bug A: When STATE.md Current Position has no recognized labels (narrative
prose), emit a warning field so the workflow detects the no-op instead
of continuing with stale state.

Bug B: Sync progress.total_plans in the YAML frontmatter when a plan
count is provided, preventing contradictory state between frontmatter
(0) and body (actual count). This writes the explicitly-provided count,
not a re-derivation from disk (#500 safe).

a54feb4216 fix(#2440): per-counter progress ratchet — total_plans always takes derived value (#2468)
* fix(#2440): per-counter progress ratchet — total_plans always takes derived value

Two sites fixed (targeted — existing body-only write tests preserved):

Site A — read path: shouldPreserveExistingProgress (state-document.cts:167)
removed total_plans from the all-or-nothing ratchet check. It now joins
total_phases as an always-derived counter. Only completed_phases and
completed_plans keep ratchet behaviour (they are monotonic). This fixes
gsd-tools query state.json reporting stale total_plans when a curated
completed_plans triggers the ratchet.

Site B — write path: applyStatePreservation (state-transition.cts:162)
gained a deriveProgressKeys opt-in flag. When true (passed by
cmdStatePlannedPhase only), total_plans and total_phases take the
derived (post-sync) value instead of the wholesale curated restore.
When false (the default — state.update, state.patch), the existing
#3242 wholesale protection stays fully in force. This fixes the
state planned-phase verb writing a stale total_plans.

The opt-in approach preserves all 8 existing #3242/#1264/#500 body-only
write tests that assert wholesale progress preservation during non-
progress updates.

Tests:
- tests/state.test.cjs: 4 unit tests for shouldPreserveExistingProgress
  (total_plans upward/downward/equality + completed_plans ratchet active).
- tests/state-transition.test.cjs: 2 #2440 regression tests for
  deriveProgressKeys=true (total_plans takes derived; boundary at equality).
  The existing !resync wholesale-restore test stays unchanged (default
  behavior preserved).

References: #2440; #1446 (total_phases read-path fix — same principle);
#3242 Bug A (body-only preservation — protection preserved via the opt-in
gate); ADR-1769 (applyStatePreservation table-driven preservation).

* fix(#2204): phase-completion writes 'All phases complete' per ADR-2207

completePhaseCore was writing the overloaded bare 'Milestone complete' on the
last phase — the same string space the milestone-close verb owns for terminal
state. Per ADR-2207, phase-completion now writes the existing intermediate
value 'All phases complete' (already used in gsd2-import.cts). Milestone
termination ('<version> milestone complete' / 'Awaiting next milestone')
remains solely with milestoneCompleteCore.

* 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).

* 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).

Deleting the final row of a table with no trailing EOL sliced from the row's

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 /

  old code silently summed the wrong column). Marker removed.
- uat.cts parseVerificationItems: loose pipe regex → splitTableRow within the

- eslint no-adhoc-markdown-parsing: close the `new RegExp(identifier)` recall

- 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

* 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.

phase-list checkbox flip (`- [ ] Phase N …` → `- [x] … (completed <date>)`)
off its whole-slice regex onto it, same milestone-slice scope + clock seam.

* 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.

* 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.

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.

50ff7a8707 fix(#1776): scope prune phase resolution to ## Current Position (#1832)
* fix(#1776): scope prune phase resolution to ## Current Position

cmdStatePrune resolved the current phase by extracting the `Phase` field over
the WHOLE STATE.md body. stateExtractField's fallback chain ends in a pipe-table
match (`| Phase | N |`), so a STATE.md lacking a `Current Phase` field and a
prose `Phase:` line — but carrying an unrelated `Phase`-labelled table row (e.g.
a historical verification table) — resolved that stale table cell as the current
phase and computed a wrong cutoff (bailing "Only N phases" or pruning at a stale
boundary).

Resolve the phase via the same canonical chain buildStateFrontmatter uses —
frontmatter `current_phase` → `Current Phase` field → prose `Phase: X of Y` —
but scope ONLY the prose term to the `## Current Position` section via the
fence-aware locateCurrentPosition seam (new exported sliceCurrentPositionSection).
Frontmatter and the explicit `Current Phase` field stay document-wide (they are
unambiguous); the shared stateExtractField is not narrowed for any other caller.

Tests (folded into tests/state-prune.test.cjs): a stray `| Phase | 2 |` table
with the real phase in frontmatter no longer drives the cutoff (fail-first on
base); template-conformant STATE.md is unchanged; and a fast-check
boundary-containment property that a `| Phase | N |` row outside Current Position
never leaks into the scoped resolution.

f65866f17d fix(#1831): resolve ESLint errors and unused-var warnings from #1829/#1830
Two hard errors in src/state-transition.cts:
- reconcileCurrentPosition: `!== null` guards on `Record<string,unknown>`
  values don't narrow the type to a primitive, causing
  @typescript-eslint/no-base-to-string to fire on String(fm.current_phase)
  and String(fm.current_phase_name). Extract to typed locals + use typeof
  narrowing so the rule sees string | number — which is the actual invariant.

Four unused-var warnings (warnings are still defects per RULESET):
- stripTemplatePlaceholders: `placeholder` was assigned value.trim() but
  never read — the value came from the loop variable itself, so removed.
- deduplicateSessionArchive: `sectionContent` was sliced but the filter
  below uses the raw hs offsets directly — variable was dead code; removed.
- state-rebuild.test.cjs: first transitionCore call in the orphan-row test
  is covered by the dedicated Leaky-Abstractions guard test below it;
  remove the no-op call rather than silently ignoring its result.
- state-rebuild.test.cjs: `before = state` in the sync regression guard
  test was never read — remove the dead assignment.

b5c8a3e590 feat(#1827): rebuildCore + rebuild intent + drift-class unit tests (#1829)
Phase 1 of approved feature #1817. Implements the body-structure
derivability contract landed in ADR-1817 (Phase 0, PR #1828).

Source changes (src/state-transition.cts):
- Add `rebuild` as the 11th intent in StateTransitionIntent (ADR-1769
  transition set extended per ADR-1817 §1).
- Add `phaseInventoryProvider` optional dep + PhaseInventoryRecord type
  (Leaky-Abstractions guard: pure core stays testable without disk I/O;
  rebuild skips table reconciliation when the provider is absent).
- Add `case 'rebuild':` dispatch arm to transitionCore (the missing-case
  compile-time guarantee extends to the 11th case).
- Implement rebuildCore orchestrator + four drift-class helpers per
  ADR-1817 §2:
    * reconcileCurrentPosition — body prose re-derived from frontmatter
    * reconcileByPhaseTable — **By Phase:** table re-derived from disk
      inventory via the new dep
    * stripTemplatePlaceholders — `**Field:** [placeholder]` →
      `**Field:** (pending)` (no canonical source available)
    * deduplicateSessionArchive — keep most-recent 3 archived H3 blocks
- Implement appendRebuildLogSection per ADR-1817 §3 — every mutation
  appends a structured entry (timestamp/kind/section/before/after/reason)
  to `## Rebuild Log`. Idempotency guarantee (ADR-1817 §4): a no-mutation
  rebuild appends NO log entry, so two successive runs on a clean file
  are byte-identical.

Compiled output (gsd-core/bin/lib/state-transition.cjs): regenerated via
`npm run build:lib` (tsc -p tsconfig.build.json).

Tests (tests/state-rebuild.test.cjs, 18 cases):
- Dispatch + idempotency contract (3 tests, including the load-bearing
  'rebuild on a clean file is a no-op' that pins §4).
- Current Position prose reconciliation, criterion #1 (3 tests).
- Template-placeholder removal, criterion #3 (3 tests).
- Session Continuity Archive de-duplication, criterion #4 (4 tests).
- **By Phase:** table reconciliation via phaseInventoryProvider, criterion
  #2 (3 tests, including the Leaky-Abstractions no-op guard).
- Regression guard for sync + prune, criterion #7 (2 tests).

Verified: node --test tests/state-rebuild.test.cjs → 18/18 pass.
Verified: node --test tests/state-transition.test.cjs → 85/85 pass (no
regression on the existing 10 transitions).

Phase 2 (#1826) wires the CLI surface (cmdStateRebuild + --dry-run +
integration tests + docs + changeset). This PR adds the engine only — no
user-visible command yet, so no-changelog label applied.

21f0b4316f refactor(#1796): ADR-1769 Path A — finish STATE.md preservation consolidation (#1799)
Extract readModifyWriteStateMd's post-sync preservation block into a pure,
field-classification-table-driven applyStatePreservation in the STATE.md
Transition Module. progress / status / stopped_at now join current_phase_name
as table-governed (getFieldClassification), so a preservation-policy change is
a one-row table edit instead of a per-call-site patch.

This realizes the consolidation ADR-1769 / CONTEXT.md already claimed shipped
('Absorbs readModifyWriteStateMd post-sync preservation block') and routes the
#1264 preservation policy through the single field-classification table — the
bug class is now structurally guarded by the table, not just the call-site
shouldResync flag.

Behavior is byte-identical to the pre-amendment inline block (Hyrum-safe — the
15 readModifyWriteStateMd callers' observable preservation is unchanged):
- state/frontmatter/transition + bug regression suite: 847 pass
- phase/milestone/verify (other RMW consumers): 582 pass
- codex (gpt-5.5/high) adversarial review: CLEAN (58,564-case equiv sweep)

ADR-1769 amendment appended documenting #1796.

79c69d443b refactor(#1793): ADR-1769 Phase 7 — sync, prune, update migrations (#1760, #1761) (#1794)
Migrate cmdStateSync, cmdStatePrune, cmdStateUpdate (state.cts) onto the
STATE.md Transition Module substrate and close the maintenance bug pair
#1760/#1761 (ADR-1769, epic #1769). Completes the substrate: all 10
lifecycle/maintenance transitions now route through transitionCore.

- Add {kind: 'sync'|'prune'|'update'} to StateTransitionIntent with syncCore,
  pruneCore, updateCore in src/state-transition.cts.
- updateCore: body-only single-field update (strip/reassemble), mirroring the
  pre-migration cmdStateUpdate contract.
- pruneCore: pure content→content section pruning (Decisions / Recently
  Completed / resolved Blockers / Performance Metrics rows at or below cutoff),
  byte-identical tokenizeHeadings splicing. Adapter owns currentPhase, dry-run,
  and STATE-ARCHIVE.md.
- syncCore: body writes (Total Plans in Phase, Progress bar, Last Activity)
  given disk-derived numbers. Adapter owns the disk scan + roadmap scope.
- #1760: cmdStatePrune now derives currentPhase from 'Current Phase' OR 'Phase'
  (the canonical template emits 'Phase: X of Y'), so prune engages on
  template-conformant STATE.md instead of bailing 'Only 0 phases'.
- #1761: cmdStateSync skips the Progress write (percent=null) when a milestone
  version is set in frontmatter but the ROADMAP has no versioned heading for it
  (milestone cannot be bounded). Projects without a milestone version are
  unaffected. Leaves progress untouched rather than silently writing fallback-
  derived wrong values.
- Regression: bug-1760 (prune engages on template field) + bug-1761 (sync
  leaves progress untouched when unbounded). ADR-1769 marked Accepted.

All 82 transition + 515 regression tests pass.

064f63b299 refactor(#1791): ADR-1769 Phase 6 — patch migration + curated current_phase_name preserve (#1695) (#1792)
Migrate cmdStatePatch (state.cts) onto the STATE.md Transition Module substrate
and close the curated-field clobber bug class #1743/#1695 (ADR-1769, epic #1769).

- Add {kind: 'patch'} to StateTransitionIntent, with patchCore in
  src/state-transition.cts. Applies each caller-supplied {field:value} pair via
  stateReplaceField over the full content (body + frontmatter), tracking
  updated vs. failed. data.updated/data.failed mirror the CLI output shape.
- Collapse cmdStatePatch to a transitionCore dispatch. Field-name validation
  (security) and the resync-progress decision stay in the adapter.
- #1695/#1743 fix: extend the #1230 delta heuristic in readModifyWriteStateMd to
  the curated current_phase_name, table-driven via
  getFieldClassification('current_phase_name').preservation === 'preserve-always'.
  When a write does NOT change the body Phase: source line, the curated
  frontmatter value wins over syncStateFrontmatter's body re-derivation (which
  harvests a wrong parenthetical aside — #1695). begin/planned/complete-phase
  rewrite their body Phase line, so the delta does not fire for them and
  current_phase_name still advances.
- Regression: bug-1695-state-patch-clobbers-phase-name.test.cjs — unrelated
  patch preserves curated current_phase_name; patching the Phase source advances.

All 70 transition + 493 regression tests pass (state/phase/milestone + #905/#397/#3242 lineages).

3ceb83329d refactor(#1789): ADR-1769 Phase 5 — milestoneComplete migration (#1790)
Migrate the STATE.md write path inside cmdMilestoneComplete (milestone.cts)
onto the STATE.md Transition Module substrate (ADR-1769, epic #1769).

- Add {kind: 'milestoneComplete'} to StateTransitionIntent, with
  milestoneCompleteCore in src/state-transition.cts (consulting the
  field-classification table). Owns the closure write: Status
  ('<version> milestone complete'), Last Activity, Last Activity Description,
  a Current Position reset to 'Awaiting next milestone', and an Operator Next
  Steps reset pointing at the next-milestone command.
- Collapse the inline STATE.md transform in cmdMilestoneComplete to a
  transitionCore dispatch. The adapter retains writeStateMd (lock + steady-state
  syncStateFrontmatter post-sync) and resolves the runtime-specific
  next-milestone slash command, injecting it via intent.nextMilestoneCommand.
- The two section resets carry their pre-seam allow-adhoc-markdown waivers
  (regex semantics pinned by existing tests; pending collectSection #1372).
- realClock.today() is byte-identical to milestone.cts's local today
  (both new Date().toISOString().split('T')[0]).
- Characterization tests pin field updates, both section resets (replace +
  insert paths), and frontmatter #1255 parity.

All 66 transition + milestone + state tests pass.

Migrate cmdStatePlannedPhase and cmdStateMilestoneSwitch (state.cts) onto the
STATE.md Transition Module substrate (ADR-1769, epic #1769).

- Add {kind: 'plannedPhase'} and {kind: 'milestoneSwitch'} to
  StateTransitionIntent, with plannedPhaseCore and milestoneSwitchCore in
  src/state-transition.cts (consulting the field-classification table).
- plannedPhaseCore owns the template-aware Status/Last Activity updates, Total
  Plans in Phase, Last Activity Description, and the Current Position section
  (via the inlined mutateCurrentPositionForAdvance twin). The adapter keeps the
  resync:false readModifyWriteStateMd wrapper (#500 RC1).
- milestoneSwitchCore owns the new-milestone reset: rebuilt frontmatter
  (milestone/name/status='planning'/zeroed progress) + Current Position body
  reset. The adapter keeps acquireStateLock + platformWriteSync (NOT
  readModifyWriteStateMd — milestoneSwitch rebuilds frontmatter directly).
- Collapse both callbacks to transitionCore dispatches. The now-dead
  updateCurrentPositionFields helper and KNOWN_STATUS_PATTERNS import are
  removed (their behavior lives in the transition module's
  mutateCurrentPositionForAdvance).
- Characterization tests pin the template-aware preserve-authored invariant,
  Total Plans, Last Activity narrative, Current Position update, and the full
  milestone reset (frontmatter + position body + gsd_state_version preserve +
  Accumulated Context preserve).

All 58 transition + 177 state + phase + bug-2630/bug-905 regression tests pass.

Migrate the STATE.md write path inside cmdPhaseComplete (phase.cts) onto the
STATE.md Transition Module substrate (ADR-1769, epic #1769).

- Add {kind: 'completePhase'} to StateTransitionIntent + completePhaseCore in
  src/state-transition.cts. Pure body field mutations (Current Phase shape/name,
  Status, Current Plan, Last Activity + Description, Completed/Total Phases +
  Progress percent), consulting the field-classification table for touched keys.
  Roadmap progress injected via a new optional deps.roadmapProvider.
- Collapse the ~90-line inline STATE.md transform in cmdPhaseComplete to a
  transitionCore dispatch. The adapter retains updatePerformanceMetricsSection
  (section table) + syncStateFrontmatter (disk-scan post-sync) and the
  multi-file atomic transaction (STATE is committed with ROADMAP/REQUIREMENTS,
  so readModifyWriteStateMd is not used here).
- deriveProgressFromRoadmap/clampPercent/stateReplaceFieldWithFallback move from
  the phase.cts call site into the pure core (no circular dep: phase-lifecycle
  and state-document don't import state.cts).
- Characterization tests in tests/state-transition.test.cjs pin the field
  updates, roadmap progress derivation, #1255 frontmatter parity, and the
  'Phase:' fallback. All 44 transition + 193 phase tests pass.

No user-visible behavior change. cmdPhaseComplete CLI output and 'phase complete'
behavior unchanged.

Migrates cmdStateAdvancePlan (~80-line RMW callback) onto the
transitionCore dispatch established in Phase 1 (#1775):

- src/state-transition.cts:
  - Add {kind: 'advancePlan'} to StateTransitionIntent union
  - Extend StateTransitionResult with optional data field for
    intent-specific output (advanced, currentPlan, totalPlans)
  - advancePlanCore: parses legacy + compound plan formats, handles
    advance vs phase-complete branching, strips frontmatter before
    body mutation (#1255 pattern — codex Phase 2 HIGH finding),
    uses stateReplaceFieldIfTemplate for template-default-aware
    field replacement (Knuth invariant), mutates ## Current Position
    section via mutateCurrentPositionForAdvance
  - mutateCurrentPositionForAdvance: inlined section mutation (avoids
    circular dep with state.cjs's updateCurrentPositionFields)

- src/state.cts:cmdStateAdvancePlan: collapsed to 30-line dispatch

- tests/state-transition.test.cjs: 5 characterization tests
  (advance, phase-complete, error, compound format, frontmatter #1255)

Codex gpt-5.5/high review: 1 HIGH blocking (frontmatter strip — fixed),

* refactor(#1771): ADR-1769 Phase 1 — STATE.md Transition Module substrate + beginPhase

Lands the Phase 1 substrate per ADR-1769:

- src/state-transition.cts (new Module):
  - Field-classification table (FieldClass enum + FIELD_CLASSIFICATION rows)
  - STATE_MD_SECTIONS constants block
  - Pure transitionCore(content, intent, deps) dispatch
  - beginPhase intent implementation (first-time + #3127 resume paths)

- src/state.cts:cmdStateBeginPhase — collapses ~190 lines to a thin
  dispatch onto transitionCore via readModifyWriteStateMd. The lock,
  no-op write guard, and #1230 post-sync delta heuristic stay in the
  RMW seam; the body-mutation policy moves to transitionCore.

- tests/state-transition.test.cjs (24 tests):
  - Substrate invariants (table enum, section constants)
  - Characterization: 6 first-time body field updates
  - Characterization: 5 #3127 idempotency-guard resume behaviors
  - Characterization: 3 Current Position section mutations
  - Characterization: Current focus body text line (#1104)
  - Property (RULESET.TESTS.property-based-testing): beginPhase status
    propagation + FIELD_CLASSIFICATION own-property contract
  - Resume Current Position mutation (preserves Plan/Phase/Status)

No external behavior change. Full state.test.cjs regression (177 tests)
plus bug-3127/#3242/#905/#948 pass. Property tests surfaced two
pre-existing quirks (state-document.cjs greedy \s* on whitespace-only
field values; Object.prototype method leakage on FIELD_CLASSIFICATION
lookups for strings like 'toString') — documented in test comments;
fix-out-of-scope for Phase 1.

Closes #1771

* refactor(#1771): ADR-1769 Phase 1 codex review corrections

Addresses 3 blocking findings from codex gpt-5.5/high review:

1. FIELD_CLASSIFICATION shape (state-transition.cts):
   - Was flat FieldClass enum (collapsed source + preservation)
   - Now two-column {source, preservation} rows per ADR-1769 §4
   - Added missing fields verified via Memtrace against
     buildStateFrontmatter (state.cts:1633-1653): gsd_state_version,
     last_updated, last_activity_desc, progress.{total_phases,
     completed_phases, total_plans, completed_plans, percent}
   - Field 2-7 preservation dispatch can now consult the table

2. Prototype-pollution hardening (state-transition.cts):
   - Table is now Object.freeze(Object.assign(Object.create(null), {...}))
   - getFieldClassification() helper uses Object.hasOwn; returns null
     for inherited prototype methods (toString/valueOf/__proto__)
   - Old code: FIELD_CLASSIFICATION['toString'] returned the function

3. STATE_MD_SECTIONS aligned to canonical template:
   - Verified against gsd-core/templates/state.md via Memtrace
   - Was: 8 entries including non-template sections (## Session,
     ## Decisions, ## Operator Next Steps, ## Session Log,
     ## Roadmap Evolution)
   - Now: 6 canonical top-level sections (## Project Reference,
     ## Current Position, ## Performance Metrics, ## Accumulated
     Context, ## Deferred Items, ## Session Continuity)

Also: beginPhase now consults getFieldClassification() per touched
field (codex finding: 'table not consulted by transitionCore').
Unknown fields raise immediately — adding a field without a table
row is caught at runtime.

Repo-hygiene catches from gsd-test (not node --test, which missed
these):
- gsd-core/bin/lib/state-transition.cjs added to eslint.config.mjs
  ignore list (ADR-457 tsc-generated)
- docs/INVENTORY-MANIFEST.json regenerated via
  node scripts/gen-inventory-manifest.cjs --write

Property test for Object.prototype leakage tightened to verify
getFieldClassification() returns null for toString/valueOf/__proto__.

Ref #1771

* fix(#1771): cast Object.create(null) to satisfy @typescript-eslint/no-unsafe-assignment

ESLint CI failed on src/state-transition.cts:72:14 — Object.create(null)
returns `any`, which leaked through Object.assign to the typed
`FIELD_CLASSIFICATION` declaration. Adding an explicit cast to
`Record<string, FieldClassification>` eliminates the unsafe-assignment
while preserving the null-prototype protection codex review recommended.

gsd-test: 21888/21888 PASS.

* fix(#1771): add 'see #1771' to allow-test-rule exemption per ADR-456

CI lint-allow-test-rule-refs failed: 'New allow-test-rule exemption
without an issue ref — add `see #NNN` per ADR-456'. Updated comment
on tests/state-transition.test.cjs to reference the Phase 1 issue.

* fix(#1771): remove unnecessary allow-test-rule exemption

The exemption was added speculatively. The test file does not use
readFileSync + .includes()/.match()/.startsWith() on source content —
it calls transitionCore() with string literals and verifies results
via stateExtractField() and array .includes() on the updated[] array.
No exemption needed.
