fa41bfec5c enhance(#3942): the emitted-drift ack is PR-lifetime data — move it to a commit trailer (#3954)
* test(#3942): failing-first suite for the emitted-drift ack commit trailer

Binds 37 input classes from the phase test matrix to the behavior ADR-3942
specifies, before any of it exists. Stubs return benign empty values rather
than throwing, deliberately: several rows assert that something DOES throw
(cap overflow, uncomputable commit range), and a throwing stub would turn
those green for the wrong reason and destroy the red.

The two rows that carry the design's load:

- merge-base semantics. The range is $(git merge-base base HEAD)..HEAD, not
  base..HEAD, because changedPaths comes from `git diff base...HEAD` (three
  dot). Two-dot would let the ack set and the change set disagree about which
  commits are this PR's. The fixture forks a topic branch, puts a trailer on
  each side, and asserts only the topic-side trailer is in range.

- fail-closed on an uncomputable range. With fragments a depth-1 checkout
  passes VACUOUSLY, every fragment reading as brand-new. With trailers the
  range cannot be computed at all, and returning an empty set would silently
  disarm the gate, so it must throw. The fixture builds a genuine shallow
  clone rather than simulating one.

Also covers the self-inflicted case: this change's own documentation quotes
the trailer syntax, so an example landing at the end of a commit message would
arm a live acknowledgment keyed on the literal placeholder text. Keys carrying
angle brackets or whitespace are rejected.

Authored per the phase artifacts 40-design.md and 50-test-matrix.md.
Not yet run on the remote runner — this commit exists to be tested.

* chore(#3942): move the emitted-drift ack to a commit trailer

Implements ADR-3942, superseding ADR-2719 section 3 and its #2789 amendment.
Sections 1, 2 and 4-7 are retained: the conservation law is unchanged, only the
storage of its escape hatch moved off the working tree.

An acknowledgment explains one PR's ripple, and the moment that PR merges the
ripple is in the base, so it can never clear anything again. It was stored in
permanent shared state anyway, and every consequence of that mismatch had to be
built and then maintained. The chain is #2789 -> #2914 -> #3078 -> #3842 ->
#3823 -> #3875, each fix generating the next defect, ending in a scheduled
sweeper whose own first PR could not merge itself.

Added
  parseAckTrailers + renderAckTrailer (pure) and readAckTrailers (IO shell),
  reading Emitted-Drift-Ack-Hash: / Emitted-Drift-Ack-Growth: trailers over
  the merge-base range. tests/emitted-ack-trailer.test.cjs, 37 cases, written
  failing-first and confirmed red before any of this existed.

Changed
  diffEmitted takes two structurally distinct key-space maps instead of one
  shared paths map. That closes a latent defect: the spaces were separated by
  convention only, so a growth key satisfied a hash lookup by naming
  coincidence. staleAcks now reports which space a key was declared in.
  REMEDIATION teaches the trailer, per space, with its example rendered through
  renderAckTrailer so the taught grammar cannot drift from what the parser
  accepts.

Removed
  the sweep workflow, the guard-no-ack-on-next job, the standalone linter and
  its lint:ci entry, the fragment directory and its three spent fragments, the
  legacy single-file union, and the baseAck/spentAcks mechanism -- spentness is
  now structural, not computed.

Two range properties carry the design and are pinned by tests rather than
asserted: the range is merge-base scoped, matching git diff base...HEAD, so an
already-merged trailer is out of range by construction; and an uncomputable
range throws instead of reading as zero acknowledgments, which is the inverse
of the fragment guard's vacuous pass.

Three deliberate observable changes, each disclosed in the changeset: the
unread runtime field is gone, the legacy file is no longer read, and cross-space
excusal no longer works.

Ten open PRs carry fragments and will meet a modify/delete conflict. Measured
before landing and accepted deliberately; the one-line migration is in the PR
body.

Verified: lint:ci exit 0. Remote runner to follow on this exact sha.

* fix(#3942): silent trailer collapse, lost coverage, and an unbounded cap

Six findings from the orthogonal review round, all fixed in place.

BLOCKER -- two trailers of the same name on one commit collapsed silently.
readAckTrailers built `separator=1d` where git needs `separator=%x1d`: the
`separator=` value inside a %(trailers:...) placeholder is itself a
pretty-format string, so the bare hex was emitted as two literal characters
and the split on \x1d never matched. Two same-name trailers therefore joined
into one value with errors empty -- the first reason absorbing the second
entry's key. Silent truncation, the exact class MAX_ACK_TRAILERS throws to
prevent. Confirmed with od -c against real git output before and after.

The failing-first matrix did not catch it because its "both spaces coexist"
row uses Hash plus Growth -- different trailer NAMES -- so the value separator
was never exercised. Two regression tests now cover same-name trailers
directly.

Coverage recovered: normalizeAckReason and INVISIBLE stayed on the live path
via parseAckTrailers but lost every test when the old suite was pruned. Back
under test against the current surface -- all six invisible codepoints
individually, whitespace collapse, trim, CRLF, and two seeded fast-check
properties. Dropping any single codepoint now fails.

MAX_ACK_TRAILERS counted raw trailers before de-duplication, so one trailer
carried forward across rebased commits counted once per commit and could throw
on a legitimate branch. Now counts distinct entries; 100 identical repeats
dedupe to one.

diffEmitted validated baseline, current and changedPaths but not the new
ackHash/ackGrowth, so a bad shape raised an unhandled TypeError instead of an
error verdict -- the same defect shape this file documents for #2778.

Docs: CONTRIBUTING and TESTING-SUITES were rewritten only in their first
sections; the later passages still taught fragments, git rm and the deleted
guard, contradicting the new text directly above them. Finished.

Also extends lint-removed-but-needed to exempt docs/adr and docs/research.
That gate fails on any docs mention of a file deleted in the same diff, which
makes it impossible to document a deletion in the PR performing it -- an ADR's
whole job is naming what it retired. Exemption is narrow and comes with a test
proving the gate still fires for a live consumer elsewhere under docs/. A
guard that cannot fail is worse than no guard. Maintainer-approved.

CONTEXT.md names the retired machinery by role rather than by filename: its
generated projection lands in docs/, which that gate does scan.

Adds docs/how-to/acknowledge-emitted-drift.md. The required docs set is
Reference and Explanation, so the task quadrant can be empty with every gate
green -- and this change has a real multi-step journey, including the fragment
migration ten open PRs now need.

lint:ci exit 0.

* docs(#3942): correct the duplicate-trailer rule in CONTRIBUTING

Both axes of the code review independently flagged the same passage, without
seeing each other's output.

It claimed two declarations of the same key are always "a hard, loudly-reported
error, not a silent last-wins". That is only half true, and the missing half is
the one contributors hit: identical declarations -- same key, same reason --
dedupe silently, because a trailer legitimately survives a rebase and reappears
on every rebased commit. Failing there would red a branch for doing nothing
wrong, which is exactly why the dedup exists.

Only a same-key/different-reason pair errors, and that one is a genuine
ambiguity about which explanation holds.

As written, the paragraph told a contributor that a rebase-carried trailer
breaks the gate -- the opposite of the behavior. CONTEXT.md's parallel entry
already stated it correctly; this brings CONTRIBUTING into line.

Doc-only, root-level markdown.

1e67ec9737 enhance(#3908): the scanners distinguish an empty diff from one they could not compute (#3937)
* feat(#3908): the scanners distinguish an empty diff from one they could not compute

collect_files ended 2>/dev/null || true, which destroyed the evidence three ways: the redirect discarded git's diagnostic, the pipe replaced git's status with grep's, and || true forced success regardless. Four distinct conditions - an established-empty diff, a bad ref, no repository, and a repository with no commits - all reported clean, and a secret scanner reporting clean because git failed is indistinguishable from an all-clear to any gate consuming it.

git now runs separately from the filter so its status and diagnostic both survive. An established-empty diff exits NO_INPUT; a scope that could not be established exits UNAVAILABLE; the usage sites move off 2 to USAGE. || true is retained on the filter alone, where it is correct: a diff of only images is empty, not failed.

Codes are sourced from a generated shell fragment rather than written into three scripts, so a re-allocation cannot desync them, and a missing fragment fails loudly instead of falling back to literals. The security workflow is updated in the same change: without it, a docs-only PR would newly fail the job.

* fix(#3908): keep scanner stderr out of the file list, and drop try/finally from test bodies

Capturing git and find output with 2>&1 was right for the failure path but wrong for the success path: a warning emitted alongside a successful diff flowed into the file list and was treated as a filename. stderr is now captured separately, forwarded as a warning on success and as the diagnostic on failure, and never folded into the list.

Also converts the control tests' try/finally blocks to t.after(), which CONTRIBUTING bans inside a test body because it masks failures.

* chore(#3908): backfill changeset pr number

* docs(#3908): record the scanners' four-outcome exit contract

SECURITY.md is root-level, so the docs gate correctly held: a Changed fragment owes a file under docs/. The contract also belongs where the feature is described, as REQ-SCAN-INJ-05.

docs/FEATURES.md is GENERATED from per-feature fragments (#3840) - the first edit went into the generated file and gen-features --check caught it, which is the same edit-the-output drift this epic exists to close. The fragment is the source; FEATURES.md is regenerated.

c5f2b94b27 enhance(#3907): gates report no-input instead of a verdict they never reached (#3932)
* feat(#3907): gates report no-input instead of asserting a verdict they never reached

The three stdin-reading gates bound 2 to a stdin read error only, with no arm for stdin closed at zero bytes - so empty input flowed into the detector, found nothing, and exited 1, which each module's own comment defines as a negative verdict. An unset PHASE_SECTION made the UI gate assert the phase has no UI. Empty and whitespace-only input now exit NO_INPUT, and a read error exits UNAVAILABLE rather than a locally-invented 2, both resolved through the registry and delivered by terminateNow.

The exit code was only half of it: under --json the same input emitted {detected:false}, byte-identical to the fabricated payload #3909 exists to fix, and the blocking coverage gate reads that payload. Empty input now emits the in-tree {skipped:true,reason} form with no detected key at all.

teams-status is excluded: it never reads stdin and has no invented 2, so the four-module framing in the issue and ADR is wrong. The dead root bin/lib/ui-safety-gate.cjs is deleted - no installer reference, no workflow invocation, and the live fallback chains are for other modules. Its removal restores the unit tests to the module that actually ships; they had been asserting the stale copy's two-field shape, which is why it drifted unnoticed.

* fix(#3907): drive gate tests through the process seam, and make removed-but-needed basename-precise

CONTRIBUTING requires every subprocess go through tests/helpers/process-seam.cjs; two of the three gate suites hand-rolled spawnSync while the third, added in the same change, used runNode correctly for the identical injection case. Converted the blocks this change added, leaving pre-existing ones alone.

Deleting one of two files sharing a basename made lint-removed-but-needed report 14 references that were all to the surviving canonical module - the false-positive class its own docstring names. It now matches on the deleted file's full path when a surviving file shares its basename, which is more precise rather than weaker: a genuine full-path reference still fails, and behaviour is unchanged when no basename collides. It immediately caught a docstring on this branch that spelled the deleted path.

* test(#3907): update the one existing assertion that pinned the old empty-stdin verdict

A pre-existing test asserted exit 1 on empty stdin - the defect this phase removes - and was missed because the change added new blocks without auditing existing ones pinning the old contract. Audited the rest: the other three status-1 assertions in that file all feed real input and are the genuine-negative controls that must keep returning 1, so exactly one was stale. The retired 2 is gone from the describe's contract comment too.

941b62249e enhance(#3906): two terminators over one registry, with a versioned exit projection (#3924)
* feat(#3906): two terminators over one registry, with a versioned projection

Adds terminateNow (write-then-terminate, for callers that cannot wait for the event loop) beside runMain (drain-then-exit), both projecting through one shared function so they cannot disagree - the parity the ADR makes mandatory. A failed write does not change the exit code: letting it propagate would fail a hook open, which is what the fail-closed branches exist to prevent.

The projection is versioned. v1 reproduces today's integers, including keeping a payload-carried degraded result at exit 0 - ADR-2980 ratified that across 60 sites and declined normalizing it on measured blast radius. v2 applies the registry. --exit-contract=v2 or GSD_EXIT_CONTRACT=v2 selects it; an unrecognized version throws rather than silently defaulting.

The registry is now emitted beside both copies of the exit module, so it resolves as a sibling in the built tree and in the committed scripts/ copy that must load on an unbuilt clone.

* fix(#3906): actually restrict code 2 to terminateNow, and generate the registry's type

The claim that terminateNow is the only place 2 can be produced was false: runMain's outcome arm applied no guard, so runMain(()=>'HOOK_DENY') set exitCode 2 through the drain path - and the parity matrix demonstrated it while calling it parity. runMain now refuses any outcome projecting to the hook-protocol code, gated on the code rather than the name so an alias cannot slip past, and the matrix asserts the restriction instead of contradicting it.

The ambient type for the generated registry was hand-written with no gate against the generator's actual output - the declared-surface-diverges-from-runtime defect class this epic exists to close, reintroduced inside it. It is now a third generated artifact covered by the same --check. Also converts every test-body try/finally to t.after().

* test(#3906): derive the glossary fixture's dependencies instead of hand-listing them

Adding a require to scripts/lib/cli-exit.cjs broke 31 tests in one suite that built its fixture from a hand-written dependency list, so the new sibling was absent and the copied script could not load. copyScriptWithDeps walks the require graph and exists for exactly this class - #3412 paid the same bill when one new require broke 82 tests across two suites. Migrating rather than adding another copyFileSync line keeps the class closed. The other nine suites referencing that path were triaged; none copies-and-spawns, so none needed migrating.

* fix(#3906): enumerate the new shipped file, drop a vendor name from shipped data, and fix three test defects

install: scripts/lib/exit-code-registry.cjs was missing from GSD_SCRIPTS_LIB_FILES, so it shipped to every install and orphaned on uninstall.

The registry gave HOOK_DENY a meaning naming one harness, and that string ships into every runtime's tree - a guard correctly caught it leaking into the hermes and qwen installs. The registry is runtime-neutral infrastructure; the vendor name belongs in the ADR, not in shipped data.

Two more fixture harnesses built their trees from hand-listed dependencies and broke on the new require; both migrated to the derived helper, and all 23 copy-and-spawn candidates were enumerated so the class is closed rather than patched. One generator test used a fixture code that collided with a real allocation, so the generator correctly reported a duplicate where the test expected drift. The large-payload test embedded a 256KB literal in the child's argv, exceeding Linux's 128KiB MAX_ARG_STRLEN so the child never started - it now builds the payload inside the child.

* chore(#3906): backfill changeset pr number

* docs(#3906): document the exit-code contract selector

P2 is the first phase of this epic with a user-invocable surface, so the flag and env var owe a reference entry. Records what actually differs between v1 and v2 today (one outcome), that an unrecognized value is rejected rather than silently defaulted, and the fail-safe property that makes switching safe.

39673ae9ff fix(#3738): antigravity global skills/agents install to ~/.gemini/config (#3921)
* test(#3738): antigravity global skills/agents must resolve under ~/.gemini/config

Regression tests (RED first): --skills-root and gsd-tools query surfaces,
install-plan dest dirs, and converter skills-path rewrite.

* fix(#3738): antigravity global skills/agents install to ~/.gemini/config

Antigravity's machine-local discovery scans ~/.gemini/config/{skills,agents};
the configHome (~/.gemini/antigravity) is deprecated for artifacts. Declare the
ADR-1239 skills/agents 'home' override on the antigravity global layout — the
same mechanism codex uses (.agents) — and divert ~/.claude/skills/ references
in converted global content to ~/.gemini/config/skills/. configHome, settings,
probe/migration semantics, and the local .agents layout are unchanged.

* fix(#3738): retire deprecated configHome artifacts via installer migration 010

Next install converges an existing antigravity install: manifest-managed
skills/gsd-*/ and agents/gsd-*.md under the configHome (a location AGY does
not scan) are removed — modified files backed up first, unmanifested and
non-gsd entries preserved — and now-empty containers retired. Global scope
only; the local .agents surface is live. Docs + inventory updated.

* fix(#3738): converter sync in bin/install.js, harness emit-root coverage, migration baseline

- bin/install.js converter gains the same ~/.claude/skills → ~/.gemini/config/
  rewrite as src (ADR-1508 dual copy must stay in sync).
- Parity-manifest walk covers home-override emit roots (extraEmitRootsFor) so
  antigravity's emitted skills/agents stay differential-visible at their new
  install root; install-tree fixture regen confirms an unchanged key set.
- skills-from-commands rule declares the antigravity converter as a
  runtime-scoped transform; one ack fragment covers the identity-classed
  workflow whose antigravity copy embeds the old skills path.
- Migration 010 checksum baseline + home-override set doc updated; existing
  tests updated to the #3738 contract (global dest, golden parity via layout
  dest, integration expectations).

* fix(#3738): tolerate an absent extra emit root on baseline-side measurement

The base tree's installer predates the home override, so <HOME>/.gemini/config
does not exist there; walk() threw ENOENT and the in-job baseline build failed.
An absent extra root is the legitimate pre-override shape — skip it.

* fix(#3738): review findings — manifest agents root, bare skills-path rewrite, guard comment

- writeManifest resolves the agents-kind home override (_kindDestDirSafe), so
  the manifest records agents at their actual install root and drift detection
  keeps working (isolated review finding 1, major).
- Converter bare forms ~/.claude/skills and $HOME/.claude/skills (no trailing
  slash) divert to ~/.gemini/config/skills instead of falling through to the
  retired configHome path (finding 2).
- real-home-guard comment updated: antigravity's global agents kind is the
  first agents-kind home override (finding 3, doc-only).
- Regression tests for both behavioral findings.

* chore(#3738): changeset fragment (pr number backfilled after PR creation)

* chore(#3738): backfill changeset PR number (3921)

* fix(#3738): sandbox HOME in tests that install antigravity global artifacts

antigravity is the first home-override runtime in the golden-parity and
skills-wrapper suites (codex is not in their runtime lists), so those tests
never needed HOME sandboxing — the real-home guard now (correctly) refuses
their un-sandboxed global installs on CI, where HOME is the passwd home.

* fix(#3738): stop the K3 sequential-sandbox env leak; sandbox L2's home-override plans

K3's two back-to-back sandboxHome calls leave HOME pointing at the first
sandbox once the after-hooks restore (each call saves the env as it found
it, so the second saves the first's sandbox as 'original'). On the windows
matrix that leaked gsd-k3-qwen-* home into the L2 property, whose
antigravity/global run then (correctly) refused via the #3712 real-home
guard — antigravity is the runtime that made L2's plan escape into
os.homedir(). K3 now manages the env with a single restore; L2 sandboxes
HOME per run, mirroring L1.

* fix(#3738): L2 property's HOME sandbox must exist on disk

The #3712 guard's sandbox exemption fails closed when identify(effectiveHome)
is 'absent' — L2 never created its configDir, so on the windows matrix (tmpdir
under the real home) the antigravity/global run refused even with HOME
sandboxed. Create the per-run sandbox dir and clean it up.

e20744eacb enhance(#3884): failure is a value — strict argv, and --pick that signals absence (#3922)
* test(#3884): failing-first coverage for strict argv and absence-signalling --pick

ADR-3473 §8.4 says failure is a value. Three families currently encode failure as
success, and this commit pins each one RED before the fix lands.

Measured on this tree, 2026-08-26:

  gsd-tools generate-slug "test" --pick nonexistent
    -> empty stdout, exit 0                                     (#3365)

  gsd-tools audit-open --pick nonexistent_field
    -> dumps the entire human-readable audit report, exit 0

  gsd-tools generate-slug "Hello World" --raw --pick bogus
    -> prints "hello-world", another field's value, exit 0

  gsd-tools query state.planned-phase 3        (positional, no --phase)
    -> exit 0; STATE.md's "Phase: 2 of 5 (Widget Support)" is overwritten to
       "Phase: null - READY TO EXECUTE" and the frontmatter gains a corrupted
       current_phase_name                                        (#3358)

tests/pick-flag.test.cjs:27 previously asserted the #3365 defect as the contract
("returns empty string for missing field", success === true). That assertion is
replaced by the required behavior rather than deleted.

The new parseNamedArgs block calls the spec-object signature that does not exist
yet, so it fails today by construction. The 11 existing behavior-lock tests are
left untouched here; they are corrected in the implementation commit.

C1/C4 assert at the consumer's output - STATE.md's bytes - per ADR-3180
Decision 4(b). A unit assertion on the parser would have passed throughout this
defect's life.

* enhance(#3884): failure is a value — strict argv, and --pick that signals absence

Implements ADR-3473 §8.4. Absence, emptiness and failure stop being interchangeable
ways to say "I could not answer".

parseNamedArgs (src/command-arg-projection.cts)
  Takes a spec object with a REQUIRED `positionals: number | 'rest'` and returns the
  hub's Result shape instead of a bare Record. Declaring the positional arity is what
  makes #3358's call site unrepresentable rather than merely detectable: an unrecognized
  flag or a token past the declared boundary is now InvalidArgs, naming the offending
  token and listing the accepted flags. The legacy positional-array call shape throws
  a TypeError — an internal invariant violation per ADR-3473 Decision 2, so a stale
  hand-written .cjs call site fails loudly instead of destructuring undefined off a
  Result. parseNamedArgsOrExit projects a failure onto the caller's error(); it is a
  projection over the one parser, not a second parser.

  Measured before, against a STATE.md with a populated phase-2 block:
    query state.planned-phase 3        (positional, no --phase)
    -> exit 0; "Phase: 2 of 5 (Widget Support)" overwritten to
       "Phase: null - READY TO EXECUTE", frontmatter gains a corrupted
       current_phase_name
  After: exit 1, `unexpected positional argument "3"`, STATE.md byte-identical.
  The flag form is unchanged and still updates STATE.md.

--pick <field> (gsd-core/bin/gsd-tools.cjs)
  extractField returns {found,value}, and the pick block no longer shares one catch
  between "output was not JSON" and "field was absent". An absent field exits 1 with
  pick_field_absent, naming the field and the keys that do exist; non-JSON output exits 1
  with pick_output_not_json instead of dumping the command's entire output. A field that
  is PRESENT with value null, '', 0 or false still prints at exit 0 — that is an answer,
  not a failure, and it is what keeps `--pick count` printing 0 on a fresh project.

  Measured before: `audit-open --pick nonexistent_field` printed the whole human-readable
  audit report at exit 0, and `generate-slug X --raw --pick bogus` printed "hello-world" —
  a different field's value, confidently, at exit 0.

  ADR-3409 Decision 7 explicitly deferred this contract fix to #3473; this is it. The
  sub-issue's "returns 0 when the count is zero OR absent" wording is superseded by the
  ADR rule it implements: zero prints 0, absence exits non-zero. Defaulting absence to 0
  would demote "could not answer" to "the answer is zero" — the hazard
  docs/how-to/resolve-unreachable-guard-findings.md already warns against.

Guard ledger (ADR-3473 Decision 6)
  scripts/lint-unreachable-guard-drift.cjs Detector A is RETIRED. Its premise — that a
  `--pick ... || echo` arm can never fire — is now false, so the shape it forbade is the
  correct idiom and keeping it would forbid the fix. Detector B (glob-consuming cat/ls,
  a nullglob mechanism this change does not touch) is retained in full, as are the shared
  scanner, the escape-marker parser and the baseline. Net: -1 detector, 0 added. The file
  is not deleted.

Call-site audit
  45 prompt-layer --pick invocations, every one a plain X=$(...) assignment — none in an
  if test, && chain, or a pipeline whose status is consumed, and no shell block in
  workflows/commands/agents/references sets -e. Of the 13 (command, field) pairs the
  prompt layer reads, 10 are always present; the 3 sometimes-absent ones each sit behind
  a prior found/existence check. No ADR-3409-class "field the command never produces"
  remains.

* fix(#3884): escape untrusted tokens in diagnostics, and cover five unpinned rows

Two review findings, both fixed here rather than recorded as limits.

1. A newline in an untrusted token forged a second stderr line.

   Before, plain-text mode:
     $ gsd-tools query state.planned-phase $'foo\nError: forged second line'
     Error: unexpected positional argument "foo
     Error: forged second line"

   After:
     Error: unexpected positional argument "foo\nError: forged second line"

   --json-errors mode was never affected — io.error runs that payload through
   JSON.stringify. Plain-text mode writes 'Error: ' + message verbatim, and the
   three new InvalidArgs reasons plus the two new --pick diagnostics all
   interpolate a token that comes straight from argv.

   Fixed with ONE shared helper, formatDiagnosticToken (src/io.cts), applied at
   every interpolation site — not a copy per site. It is deliberately NOT
   applied inside error() itself: several callers in this tree emit intentional
   multi-line diagnostics, and escaping newlines there would mangle them.

   The available-top-level-keys list needed the same treatment for a reason the
   review did not anticipate: `frontmatter get <file>` reads an ARBITRARY user
   document and echoes that document's own keys into the diagnostic. Verified
   reachable — a frontmatter key containing a newline reaches the key list — so
   formatKeyForDiagnosticList is guarding a live path, not a hypothetical one.
   Ordinary keys still render plain and unquoted; a fix that merely dropped the
   key would also have passed a "one line" assertion, so the test pins the
   escaped key's presence too.

2. Five behavior-table rows were implemented but nothing pinned them:
   B7  a dotted path that dies partway
   B9  bracket syntax on a non-array
   B10 a negative array index, in and out of range
   B14 a JSON root that is not an object
   B17 an @file: payload over 50KB

   B17 is the load-bearing one. output() writes @file:<path> instead of inline
   JSON past 50000 characters, and --pick resolves that BEFORE parsing; with no
   test, a future reordering of those two steps turns every large result into a
   false pick_output_not_json. The fixture seeds 1200 phase directories and
   measures the payload at 62474 characters, asserting the spill actually
   happened rather than assuming it.

* fix(#3884): correct the strict-argv surface against a full verification run

The first full run came back with 90 failures across 12 files, none in the new
tests. They were the argv surface telling me what it actually is. Ten root
causes; each classified before anything was changed.

I over-implemented, and that is reverted.

  ADR-3473 §8.4 says parseNamedArgs rejects "unrecognized and positional
  tokens". It says nothing about a value flag whose value is missing. Making
  that an error was my design decision, not the rule, and it broke a
  deliberately recorded contract: `--prd` with no value resolving to null
  (tests/init.test.cjs emptyPrdValueIsFalsyAndTreatedAsAbsent, row B5;
  tests/section-manifest-init-facts.test.cjs "flag-shaped value"). The
  "requires a value" branch is deleted outright rather than kept behind an
  option — an unused strictness mode is speculative generality. Unknown-flag
  and unexpected-positional rejection, which is what §8.4 actually mandates,
  is unchanged.

--wave needed a third flag kind the original design did not anticipate.

  `--wave N` is documented (commands/gsd/execute-phase.md:4,48) and the
  shipped workflow reconstructs and passes it (execute-phase.md:84), while
  #2932 records token-PRESENCE semantics: the CLI cares only that the flag
  appeared, and the value belongs to the workflow layer. That is neither a
  boolean flag nor a value flag, so `optionalValueFlags` now exists —
  presence-only in `data`, and the validation cursor consumes a following
  non-flag token so it is not reported as a stray positional. Every other
  declared boolean flag was checked against every argument-hint and prose
  usage in commands/, workflows/, agents/ and docs/; `--wave` is the only one
  of this shape.

Five tests were pinning forms that never worked.

  tests/adr857-core-without-capabilities.test.cjs passed
  `init plan-phase --phase 01-stub`, but the documented form is positional
  (docs/CLI-TOOLS.md:776) and the handler reads args[2] — which for that form
  is the literal string "--phase". Measured on the pre-fix build against a
  real .planning/phases/01-stub/ directory:

    init plan-phase 01-stub          -> phase_found=true
    init plan-phase --phase 01-stub  -> phase_found=false

  The test asserted only exit 0 and key presence, so it had been green while
  proving nothing about phase resolution. Corrected to the documented form and
  strengthened to assert phase_found === true. Same class in state.test.cjs
  (`--plan-count`, a flag that does not exist; the real one is `--plans`),
  milestone-archive.test.cjs (`init new-milestone --json`, silently ignored),
  and concurrency-safety.test.cjs (a bare positional field name whose
  OR-assertion passed because a whole-document dump happens to contain the
  substring it looked for).

Six handlers had no argv validation at all — the same #3358 shape this phase
exists to close, found while fixing the rest: init verify-work / phase-op /
review / todos / remove-workspace read args[2] with nothing checking the rest,
and validate health read --repair/--backfill through a bare args.includes()
scan that bypassed the parser entirely. All now go through the seam, so the
flag has one owner.

tests/init-debug.test.cjs rows C4/C5 asserted that an unrecognized flag must
NOT fail. That is the behavior §8.4 removes, and Decision 8 says a caller's
local expectation does not override §8, so they are inverted and renamed —
a test still called "ignores an unrecognized flag" while asserting rejection
would be its own defect. Row C6's point is its PWNED canary; that assertion is
kept verbatim and only its exit-status expectation changed, because the
hostile token is now rejected rather than absorbed.

The blast-radius estimate in 40-design.md is corrected rather than quietly
left wrong. get_impact reported MEDIUM / 8 symbols upstream, and that was
accurate for what the graph can see — parseNamedArgs's callers. It cannot see
that those callers' handlers accept argv shapes wider than the code reading
args[2] suggests, which is where the real surface was.

* fix(#3884): withdraw the validate-health tightening, finish the A2/A3 revert

Second full run: 46 failures, down from 90. Four causes, two of them mine.

Reverted `validate health` entirely — it was scope creep, and it broke a real flag.

  ~30 of the 46 read `unknown flag "--json"; accepted: --repair, --backfill`.
  The previous commit routed `validate health` through the parser on the
  reasoning that a flag should have one owner. That was wrong twice over:
  §8.4 names parseNamedArgs and count queries, and `validate health` was never
  a parseNamedArgs call site — it read its flags, just not through the parser,
  so it had no silent-drop defect to fix. Tightening it omitted `--json`, which
  the health-diagnostic suites use heavily. The handler is now byte-for-behaviour
  back to its pre-branch form. `validate context` stays converted: it genuinely
  was a call site, and its `--json` is now declared rather than read by a second
  `args.includes` scan.

  The five handlers that had NO validation at all — init verify-work / phase-op /
  review / todos / remove-workspace — stay fixed. Those read args[2] with nothing
  checking the rest, which is the #3358 shape this phase owns.

Finished the A2/A3 revert. Three tests still encoded the deleted
"a value flag with a missing value is an error" rule, including one added by the
previous commit for that rule. All three now assert the reverted null contract,
and the ones whose titles said "rejected" are renamed — a test named for a
contract it no longer asserts is its own defect.

`--wave=` and `--wave --weird` are correctly rejected. Neither is documented in
commands/gsd/execute-phase.md, gsd-core/workflows/execute-phase.md or docs/, and
neither is emitted by the shipped prompt layer, so both are unrecognized tokens
that §8.4 mandates rejecting. `doesNotConsumeFollowingFlagAsWaveValue` keeps the
property it exists for — asserted directly now, at the parser, that `--wave` does
not swallow a following flag as its value — and only its exit-status expectation
changed.

A contradiction inside this branch, surfaced by the audit and resolved the safe way.

  Two pre-existing #3573 tests call `state begin-phase '2'` and
  `state planned-phase '2'` with a bare positional, relying on the old permissive
  parser to ignore it. This branch's own #3358 regression test requires that exact
  argv to be REJECTED. The two are mutually exclusive.

  Widening the router to accept a bare positional — mirroring complete-phase —
  would have silently re-opened #3358, and was verified to do exactly that: with
  the widened router, `query state.planned-phase 3` returned exit 0 and wrote
  current_phase_name again. It is reverted. docs/CLI-TOOLS.md:116 and
  docs/COMMANDS.md:2192 document only the `--phase N` form for both verbs, so the
  two #3573 tests move to it. Their assertions were never about the call shape —
  only that total_phases survives the resync — and both still pass.

  complete-phase is untouched: its bare positional IS documented, and it keeps the
  dynamic boundary and the negative-space note that record why.

The audit that produced this is in the PR body: for every handler whose declaration
changed, the flags it reads anywhere in its body, the flags the shipped surface
documents, and the shapes the suite passes, compared. The `--json` miss was a
pattern, not an accident — declaring a handler's flags from its parseNamedArgs call
alone misses whatever it reads elsewhere.

878f25025c enhance(#3905): the exit-code registry — one number, one meaning, enforced at build (#3920)
* feat(#3905): the exit-code registry — one number, one meaning, enforced at build

A generated registry replaces locally-invented exit codes. Every entry records code, name, meaning, owning module and the decision that authorized it. The generator refuses to build a table where two entries claim one code, two claim one name, a code falls in a range Node or the shell reserves, 2 is claimed by anything but the hook adapter, or an allocation carries no justification. exitCodeFor is pure and total: it throws rather than returning undefined, including for prototype-chain names.

Inert by design — nothing emits a registered code until #3906. Every registered code is non-zero, asserted over the whole table, so a caller testing for failure behaves identically for pass and trips for everything else.

* feat(#3905): make the registry generator's failures machine-readable

Adds a --json mode carrying {ok, reason, context, detail}, where context is a typed payload naming the specifics the prose embedded - which code collided and under which names, which band rejected a code, which field was missing. The tests now assert on that structure instead of regex-matching the generator's stderr, which CONTRIBUTING prohibits, and the CONTEXT.md glossary gains the entry the issue's scope requires.

* test(#3905): refresh the install-tree fixtures for the new declaration

The registry declaration ships in the install tree, so all 19 golden fixtures needed regenerating. Caught by the remote matrix, not by lint:ci - the install-tree goldens are verified by a test rather than a lint, so a newly shipped file clears every local gate and fails only under the suite.

7e9d33c378 enhance(#3915): stryker on the official tap runner, 29m to 12m on the critical path (#3919)
* enhance(#3915): stryker on the official tap runner, per-test coverage

The 'command' runner is the one runner Stryker excludes from coverage
analysis, which forced coverageAnalysis:'off' and made mutation cost
strictly linear in (mutants x whole-shard test time). The frontmatter
shard measured 1751s against 212s for the next slowest.

Swap to @stryker-mutator/tap-runner (official plugin, peer-pinned to the
@stryker-mutator/core@9.6.1 already installed) and turn coverage analysis
on, so Stryker re-runs only the test files that cover each mutated line.

Per-shard injection moves from a MUTATION_TEST_CMD command string to
MUTATION_TEST_FILES, read by a new fail-closed resolveMutationTestFiles()
that mirrors resolveMutationBreak. It stays derived from
scripts/mutation-matrix.cjs and now has a single owner: the union moves
behind allCoveredTests() and stryker.config.mjs no longer imports COVERED.
The resolver existence-checks every entry, because the tap runner resolves
tap.testFiles with glob() and a non-matching pattern yields an empty list
silently - a fast, confident, meaningless run.

tap.forceBail is off by measurement, not preference: a structural AST
audit found 3 of 26 shard test files spawn subprocesses, and bail fires on
every killed mutant, so leaving it on would kill processes mid-spawnSync
and orphan their children.

The matrix 'isolation' field is removed - per-file process isolation is
inherent to the tap runner, so the field had no consumer left.

Score arithmetic is unchanged and now pinned: mutationScore counts
NoCoverage in the same denominator as Survived, which both Stryker's
thresholds.break and check-mutation-score-ratchet.cjs read. A new
non-vacuity test proves it diverges from mutationScoreBasedOnCoveredCode,
so the gate cannot be quietly swapped to the field that would make every
floor trivially satisfiable.

Refs #3915

* fix(#3915): enforce the resolver's documented containment contract

Review findings, all fixed in place.

resolveMutationTestFiles claimed to verify each entry exists 'relative to
the repo root' but used a bare fs.existsSync(path.join(...)), which
accepts an existing DIRECTORY and lets ../ segments escape the root
(path.join('/repo/root','../../etc/passwd') resolves to /etc/passwd).
Not reachable from PR content - the value only ever comes from the static
COVERED registry via CI env - but a fail-closed contract that overstates
its own guarantee is a defect in the contract. Each entry is now resolved,
rejected if path.relative puts it outside the root, and required to be a
regular file. Three hostile-input tests added; the original missing-file
wording is preserved so the existing assertion still binds.

Also: removed a stale buildResult comment still naming the isolation
field this branch deleted; hoisted one top-level path require in place of
three inline ones; de-duplicated the derived-test-list expression in the
tests to a single const, deliberately still re-derived from COVERED
rather than calling allCoveredTests() so the assertion cannot become a
tautology; tightened the workflow-parity assertion to exact equality;
changed the tap-runner range from an exact 9.6.1 to ^9.6.1 so it tracks
the caret-ranged core its peerDependency pins exactly.

Regenerated examples/dynamic-context-management/CONTEXT-INDEX.json, which
the earlier CONTEXT.md edit left stale - lint:ci was red on
lint-example-parser-parity until it was refreshed.

* test(#3915): kill model-catalog survivors, set frontmatter budget from measurement

From mutation run 33026833181 (all 13 shards, dispatched on this branch before any PR).

WALL TIME: frontmatter measured 713s (11m53s) vs 1751s (29m11s) on the command runner, a 59% cut. timeoutMinutes 60 -> 20 (1.68x measured). Not deleted outright: the shared 15-minute default would leave only 21% headroom, and this module's mutant count grew 1.8x in one change.

MODEL-CATALOG: came back 57.91 against its floor of 58. Diagnosed from the report JSON, not assumed - all 24 of its new RuntimeError mutants are in the load-time catalog bootstrap, so mutating them makes the module throw at require. Under node --test that is a failed test file (Killed); under the tap runner the process dies before emitting TAP, which Stryker classifies RuntimeError and excludes from the denominator. Add them back as killed and the shard is 248/416 = 59.62, the pre-change number exactly. Detection did not regress, classification changed.

The floor is NOT lowered to absorb that. 11 new behavioural tests target ~42 genuinely surviving mutants: exact Set equality on the EFFORT_RENDERING/EFFORT_ARGV supported sets, an exact-string table render that makes the column-width arithmetic observable (padEnd never truncates, so the old substring assertion could not see a too-small width), clampEffortForHost's full null matrix plus a spoofed-toString host, and a prototype-pollution guard driven through Object.fromEntries.

Mutants judged equivalent were skipped rather than papered over; reasoning is in the phase artifacts. All 15 new assertions verified against unmutated code. lint:ci exit 0.

Refs #3915

* test(#3915): ratchet model-catalog's floor to 74 on measured 75.26%

CI run 33029755081 measured model-catalog at 75.26% (295 killed / 49 survived / 48 no-coverage / 24 runtime-error, totalValid 392), so check-mutation-score-ratchet.cjs correctly failed the shard for unclaimed headroom: 17.26 points above the declared floor of 58, well past the 5-point slack.

Floor raised 58 -> 74 (floor(75.26)-1, this file's documented convention), with RATCHET_BASELINE updated in the same diff as the equality assertion requires.

Worth recording why the number moved this far. The shard first came back at 57.91 under the tap runner and the temptation was to lower the floor to match. The drop was not a regression: all 24 of its RuntimeError mutants sit in the load-time catalog bootstrap, and adding them back as killed reproduces 248/416 = 59.62, the pre-swap figure exactly. Rather than absorb a reporting artifact by weakening the gate, 11 behavioural tests went after the genuinely surviving mutants and killed 68 of them - carrying the module from 59.62 past its old ceiling to 75.26, within reach of the ADR-456 target of 80.

The #3007 measurement is kept as clearly-labelled prior context rather than deleted, so the entry does not read as carrying two current numbers.

8edace40d5 enhance(#3904): one exit module — generate the scripts-side copy from a single source (#3917)
* test(#3904): failing-first coverage for the drifted scripts-side exit module

The scripts/ copy of the CLI exit seam has no json-error arm, so an unexpected throw prints a raw stack where the documented contract promises {ok:false,reason,message}. Adds the consumer-altitude reproduction plus the negative space it must not swallow, the one-cell assertions for json-error mode, and the standalone-load constraint. RED until the generator lands.

* enhance(#3904): generate the scripts-side exit module from one source

src/cli-exit.cts becomes the single source of truth and scripts/lib/cli-exit.cjs a generated artifact of its compiled output, byte-compared by a --check entry in lint:generated-sync. The two had drifted: only the .cts copy emitted the documented {ok:false,reason,message} envelope on an unexpected throw, so a scripts-side tool printed a raw stack where docs/json-errors.md promises structured output.

The generated file is committed and must load on an unbuilt clone (64+ consumers, incl. check-env.cjs), and gsd-core/bin/lib/cli-exit.cjs is gitignored tsc output that doubles as the build sentinel, so it cannot be required from there. The exit module therefore drops its io.cjs import: the json-error-mode accessors move into it and io.cts re-exports them, leaving its export surface unchanged. The flag lives in a Symbol-keyed cell on globalThis because one source emitted to two locations means two module instances, and a module-level flag would give them two independent values.

* chore(#3904): changeset for the generated scripts-side exit module

* docs(#3904): name which surfaces honor the json-error envelope contract

docs/json-errors.md described the structured envelope as what runMain does without saying which copies of runMain actually had the branch — a claim that was silently false for every scripts/-side tool. Also drops a redundant source-grep test whose marker grew the unverified allow-test-rule pool past its ceiling; the behavioral test beside it proves the same property through real module resolution.

* test(#3904): compare exit verdicts, not stderr bytes, across the two copies

The parity test asserted byte-identical stderr, which the plain-text path cannot satisfy: the generated copy carries an 11-line banner, so its stack frames report line numbers offset by exactly that much, and the path normalizer stopped at the colon. Byte-identical stack traces were never the contract - two files at two paths necessarily differ there. Now compares the parsed envelope under json mode, the first line and exit code on the stack path, and exact output for ExitError.

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.

Refs #3881

* 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.

* 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.

Refs #3881

* 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.

Two errors in the entry as first written: it named parseYamlRegion as part of

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.

* 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.

Refs #3881

* 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.

Refs #3881

* 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).

Raised five module minScore floors per CI run 33012034388 (floor(achieved)-1):
config-schema 75.51%->74, prompt-budget 88.95%->87, context-composer 79.92%->78,

RATCHET_BASELINE in the same diff per the ratchet's own contract.

Closed the frontmatter shard's 63.03%-vs-65 gap with new behavioral tests in
tests/feat-3881-yaml-parser-consequences.test.cjs, each paired with a documented
near-miss: frontmatterDeepEqual's array-order/length/type-mismatch/key-order
semantics (via spliceFrontmatter's no-op guard), scalarNeedsDoubleQuoting's
leading/trailing-whitespace and dash/surrogate triggers (via reconstructFrontmatter),
repairAmbiguousColonValues' already-quoted vs ambiguous-colon repair paths (via

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.

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

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

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

- A1a: one sentinel flips applied false->true and confidence low->med on

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

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

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

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

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

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

buildAllPhaseDirNamesField duplicated listAllPhaseDirs's own
readdirSync + directory-filter + absent/unreadable handling — the
'one implementation per rule' defect ADR-3473 SS8.3 names, introduced
by this branch's own #3882 work. Delegate to listAllPhaseDirs and
re-apply the field's existing lexicographic sort on top, since W007's

Records listAllPhaseDirs in the Phase Locator glossary entry, and the fact
that the owner already answers the all-milestones sentinel-free question when

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

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.

8f674281fd chore(#3875): sweep the spent ack fragments and automate the sweep (#3877)
* chore(#3875): sweep the spent ack fragments and automate the sweep

next has been red on every push since a84f75630 (#3823) — 24 consecutive pushes
over two days — on two fully-spent emitted-drift-ack fragments nobody swept.

#3823 introduced guard-no-ack-on-next together with a 45-fragment sweep, but
computed that sweep as a static set of deletions fixed at its branch point.
#3809's fragment merged to next while #3823 was in flight, so the guard reds on
its own merge commit. The condition is evaluated dynamically at merge time and
remediated statically at branch time; on a moving branch the second can never
reliably satisfy the first.

- delete tests/emitted-drift-acks/3809-* and 3866-* (3034-* and 3172-* stay --
  the #3842 open-PR hold correctly defers them)
- runGuardNext returns `sweepable`, the set the guard actually reasoned about,
  plus `legacyPresent` for the legacy document, which is a fixed path rather
  than a fragment basename and would otherwise be invisible to any sweeper
- new --sweep-plan mode turns the guard into a work list: plan on stdout, prose
  on stderr, exit 0 so a non-empty plan does not fail the step that asked for it
- main() is injectable in BOTH lanes; a half-injected seam lets a test that
  passes cwd silently read the real repository instead of its fixture
- ack-fragment-sweep.yml derives its deletion list from that plan on a timer and
  opens a reviewable PR, so the sweep can no longer go stale between branch
  and merge

Hardening found in review, each verified against a live reproduction:

- git rm reads its arguments as PATHSPECS with wildmatch semantics, so a
  fragment named a bare-star .json name -- legal, and admitted by
  listFragmentFiles since it filters only on the suffix -- expanded to every
  fragment in the directory, including ones the #3842 hold withheld. Confirmed
  in a scratch repo: one such file deleted all three. Closed with a literal
  allowlist and a :(literal) pathspec, two independent layers.
- an apostrophe inside a heredoc nested in a command substitution is an
  unterminated quote and a hard syntax error at runtime, not just under bash -n.
- an empty plan no longer reports success unconditionally: the guard is re-run
  without the hold to tell "next is clean" from "everything is held", the
  commonest holder being the sweep PR from the previous run, which touches
  exactly the fragments it proposed to delete.
- a branch pushed by a run that died before it could open the PR wedged every
  later run on a non-fast-forward push; re-pointed under a lease instead.
- a guard crash in plan mode no longer reads as "nothing to sweep".

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.

382bf7c423 fix(#3706): deliver the resolved reasoning effort to OpenCode subagents (#3867)
* test(#3706): failing-first coverage for OpenCode variant emission and frontmatter escaping

* fix(#3706): emit the resolved reasoning effort as OpenCode's variant key

`query resolve-execution` resolved an effort level for every agent, but the
OpenCode bake wrote only `model:` — the effort never reached the generated
agent, so subagents ran at whatever the runtime defaulted the model to. This
is the effort-side twin of the model-side defect fixed in #3705.

The key is written only when an `effort` block is actually configured.
`resolveInstallTimeEffort` always returns a level (the catalog default is
`high`), so gating on its return value would stamp `variant: high` into every
existing OpenCode install — and OpenCode resolves a variant name against a
`variants` map in the user's `opencode.jsonc`, so a value nobody declared is
not a safe default. Gating on `readGsdEffectiveEffortConfig` keeps installs
that never asked for effort routing byte-identical.

Kilo does not receive the key: `EFFORT_ARGV` declares surfaces for claude,
opencode and codex and has no kilo entry. This is deliberately asymmetric with
the model side, where #2794 J8 requires the two runtimes to resolve alike.

Both frontmatter sinks now route through `frontmatterScalar`, which quotes and
escapes any value that is not a plain scalar. The raw interpolation predates
this change, but it was already shown by execution during the #3705 security
review to let a config value containing a newline inject additional top-level
keys (`tools:`, `permission:`) into a generated agent file. This change adds a
second write to that sink, so it is closed here rather than doubled.

* fix(#3706): quote frontmatter values YAML would not read back verbatim

Self-review of the predicate added in the previous commit. Treating
/^[A-Za-z0-9._:/@+-]+$/ as 'safe to emit bare' answers the wrong question:
a value can match it and still not round-trip.

  - A leading '@' is a YAML *reserved* indicator and may not open a plain
    scalar at all, so a scoped ID like '@org/model' emitted bare is a parse
    error, not an ambiguity — the whole agent file becomes unreadable.
  - 'no' / 'y' / 'off' / 'null' resolve to booleans and null, so a variant
    with one of those names would match no entry in the user's variants map.
  - '12:30' resolves to 750 under YAML 1.1 sexagesimal, and ':' is legal
    mid-identifier here, so the form is reachable rather than contrived.

Real model IDs pass every clause and stay bare, so already-generated files
remain byte-identical.

* fix(#3706): route variant through the declared effort seam and cover the live path

Addresses six findings from the isolated review, all confirmed by execution.

The tests were the serious one: they required `../bin/install.js` while the fix
landed in src/, which compiles to gsd-core/bin/lib/. They exercised a different
copy of the converter than the one the bake actually uses, so the whole suite
was green-by-construction against unchanged code and the remote run failed all
13. Every case now runs against BOTH copies from one table, which doubles as the
parity assertion the generative-fix note in runtime-artifact-conversion.cts asks
for, and bin/install.js carries the mirrored change.

Emission no longer hand-rolls the value. It goes through `renderEffortArgv`,
the declared OpenCode effort seam (EFFORT_ARGV.opencode: its own supported set
and clamp). That is what rejects a level that is not a wire value — above all
`inherit`, which per #3533 (10d) means "omit the key and follow the host
default" and was previously written literally, naming a variant that cannot
resolve. Reachable two ways, both now pinned: an agent_overrides entry and a
routing_tier_defaults entry. A bare effort.default does NOT reach a tiered
agent (the #3531 tier ladder answers first), so a test written against
`default` alone asserts nothing — that is pinned too.

The plain-scalar decision moved into frontmatter.cts beside
`scalarNeedsDoubleQuoting` rather than sitting next to it as a second, weaker
predicate. `agentScalarNeedsDoubleQuoting` is a documented superset: it adds a
trailing `:` (read as a nested mapping key, which fails the whole frontmatter),
boolean/null words, and numeric-looking values including YAML 1.1 sexagesimal.

Docs now state the cascade plainly: the gate is on effort being configured at
all, not on the individual agent being named, so every generated OpenCode agent
gets a variant line once any effort block exists.

* test(#3706): assert the two frontmatterScalar copies cannot diverge

A hand-picked adversarial corpus plus a fast-check property over
YAML-significant strings, both run against bin/install.js and the live
src copy. Verified the property can actually fail: mutating one copy's
quoting rule is killed well inside the run budget.

* fix(#3706): close the review findings — predicate, seam, and dead mirror

Third review round; every item below was confirmed by execution.

The scalar predicate was wrong in two families, both found by a round-trip
property test rather than by reading. Basing it on scalarNeedsDoubleQuoting
dropped the "first character must be alphanumeric" clause, so `~`, `.inf`,
`.nan`, `+1`, `-0` and `.5` went out bare and came back as null/floats/ints;
and that base predicate only inspects the FIRST character, so an embedded `: `
(a nested mapping, i.e. a parse error) or ` #` (a comment, i.e. silent
truncation) also passed. Dates round out the set: `2026-08-25` opens
alphanumeric, survives every other clause, and YAML resolves it to a Date.
The property now asserts the contract directly over generated values instead
of trusting an enumerated character list.

The bin/install.js mirror is gone. Its premise was false — install.js already
requires bin/lib at :65 — and it was unreachable besides: install.js's
convertClaudeToOpencodeFrontmatter has no `isAgent: true` call site, because
its agents path resolves converters from the compiled module. It was a third
copy of the YAML rules serving a test rather than a caller, so the file is
back to origin/next and the tests target the live copy only.

Effort clamping moved to `clampEffortForHost`, which renderEffortArgv now
delegates to. The layout was calling renderEffortArgv with a hardcoded 'argv'
to borrow its clamp, which read as if the frontmatter key were gated on the
invocation-time axis. It is not: claude declares effortSurface "argv" and
independently bakes an effort: key. One capability table, one clamp, two
channels that no longer pretend to be each other.

Also corrects an earlier claim of mine: adding EFFORT_RENDERING.opencode would
NOT have made `effort sync` write the wrong key, because it guards on the
runtime name before it ever renders. The seam choice stands on other grounds.
`effort sync` still skips OpenCode, but its stated reason claimed OpenCode
"does not use effort: frontmatter", which this change makes false — so the
message now says what is actually true.

* docs(#3706): restate the changeset around the round-trip contract

* fix(#3706): restore the changeset fragment belonging to #3809

An earlier commit in this branch picked the first file in .changeset/ by
glob order instead of the fragment created for this issue, and overwrote
agile-geese-squeak.md (PR 3815 / #3809) with this change's body. Restored
verbatim from origin/next; this change's text now lives in its own
patient-cranes-parade.md, where it was created.

* feat(#3706): maintain the OpenCode variant key from effort sync

Install bakes the resolved effort into OpenCode agent frontmatter as
`variant:`, so `effort sync` has to maintain it or a config change only takes
effect on reinstall — and its skip message claimed OpenCode does not use
frontmatter effort at all, which this issue made false.

cmdEffortSyncOpencode mirrors the codex branch: resolve per agent, clamp
through the declared OpenCode capability, then write, strip, or skip. A null
target means the key must not exist, which covers both "no effort configured"
and "resolved to inherit or to an unsupported level" — the same states under
which install writes nothing, so sync and install agree by construction.

The frontmatter line-editors are key-parameterised rather than copied:
setEffortFrontmatter / removeEffortFrontmatter are now thin wrappers over the
same internals the variant path uses, and a test pins that the claude `effort:`
behavior did not move. The child-process test harness fixes both HOME and
USERPROFILE, so the hermetic-config assertions cannot pass vacuously on Windows.

* fix(#3706): scope the frontmatter line editors to the matched block

Found by the security review of the sync path, reported as correctness rather
than vulnerability, and reproduced against pre-fix code before being fixed.

Both editors matched the frontmatter with a regex that can match a block after
a preamble, then derived the EOL and the opening-fence length from the START OF
THE FILE. On a CRLF document with a preamble those disagree, the offsets shift
by one byte, and the reassembled document comes back with a mangled fence
(`---\rname: x`). Both now take the EOL from the matched block.

`setFrontmatterKeyLine` additionally did a whole-file `/m` replace when the key
already existed, gated only on the key being present in the frontmatter body —
so a preamble line starting with the same key was rewritten instead of the
frontmatter one. It now replaces inside the frontmatter span only, which is the
hazard `removeFrontmatterKeyLine` already documented and guarded against.

Neither is reachable from an install-written `gsd-*.md` (those begin at byte 0
with `---`), and both predate this change — but the editors are in this diff
because #3706 key-parameterised them, so they are fixed here rather than left
for the next caller to trip over. Three regression tests, each confirmed to
fail against the pre-fix build.

* fix(#3706): treat a present-but-empty key as present, and pin the real seam

Fourth review round.

The MAJOR one: both sync branches read the current value with `(.+?)`, which
needs at least one character, so a key present with an EMPTY value read as
"key absent". When the target was also null the code concluded "already
correct" and skipped — leaving the key in the file, where it reads back as
YAML `null`: exactly the unresolvable-variant state this change exists to
prevent. Whitespace decided whether it fired, since `variant:   ` matched and
`variant:` did not. Presence and value are now separate questions at both the
opencode and the claude branch.

The OpenCode writer now follows the codex branch rather than the claude one:
tmp file plus retryRenameSync with orphan cleanup, and a write failure skips
that agent and is reported instead of aborting the sweep. Same granularity,
same transient-Windows-lock exposure, so the hardened sibling was the right
precedent.

Also: the generic line-editors escape their interpolated key, the JSDoc
stranded by the clampEffortForHost extraction is back on renderEffortArgv, and
a cast that declared a nullable function as non-nullable is corrected.

Tests close the gaps the review listed — empty value (both spellings), CRLF
round-trip through write and strip, the symlink guard, a body line starting
`variant:`, a file with no frontmatter, and the YAML classes that actually
broke the predicate. The new layout-seam test drives the real stage() path and
was verified to FAIL when `variant` is removed from the converter call; a seam
test that survives cutting the seam is worse than none.

* fix(#3706): clear the round-five review findings

No blockers or majors this round; the repo's review gate is zero-tolerance, so
the minors are cleared too.

A duplicated key was only half-stripped: the strip regex had no `g` flag, so a
frontmatter carrying the key twice lost one occurrence, reported success, and
left the "a null target means the key must not exist" invariant false on disk —
converging only on a second run. Such a document is already invalid YAML, so
this is robustness rather than a live corruption path, but a successful sync
has to leave the invariant true.

A run in which every write failed still summarised as `ok`, so a caller could
not tell "nothing to do" from "everything failed". The OpenCode branch now
reports `failed` when any write failed. The write-failure path was also the
newest code in the change with no coverage at all; it now has a test that
injects the failure by monkeypatching the write, per CLAUDE.md §4, rather than
by chmod — mode bits do not bite under root in CI.

`CodexEffortSyncWriteFailure` is renamed `EffortSyncWriteFailure` now that two
branches share it. Removed a guard on the claude concrete path that was
provably unreachable — no member of EFFORT_SET renders null there, so it read
as protection that did not exist. The claude inherit path's presence check is
load-bearing and untouched.

Three stale statements corrected: the OpenCode result shape matches codex's,
not claude's, now that it emits write_failures; the `thread()` test helper now
calls `clampEffortForHost` so it genuinely mirrors the layout instead of
merely claiming to; and a test helper restored `USERPROFILE` by assignment,
writing the literal string "undefined" into the environment on POSIX — it
deletes now.

* fix(#3706): converge the set path, degrade on unreadable files, preserve mode

Rounds five and six of review. No blockers or majors; the review gate is
zero-tolerance, so the minors are cleared too.

`setFrontmatterKeyLine` was the mirror of a defect already fixed in its
sibling: `remove` was made global, `set` was not, so on a frontmatter carrying
the key twice it rewrote the first and left a stale second. Last-wins YAML
readers honour the stale value while the sync's own first-occurrence read
reports "in sync" — permanently non-converging. It now collapses to exactly one
occurrence, in the position of the first, so ordinary single-occurrence
documents stay byte-identical (verified across seven shapes before and after).

An unreadable agent file used to throw and abort the entire sweep, while a
failed WRITE in the same loop degraded into a report. The OpenCode branch now
reports read failures alongside write failures; the claude branch degrades to a
skip without a new result field, because its shape is long-standing and widely
consumed and one bad file aborting the sweep is the actual defect.

The tmp+rename publish dropped the original file's mode — a plain writeFileSync
preserves it, a rename does not — so a 0600 agent came back 0644. Both the
OpenCode and the codex branch now carry the original's permission bits across
the publish, masked with 0o7777: the raw stat mode includes the file-type bits,
and POSIX leaves those unspecified for chmod. Linux is the only OS the remote
matrix runs, so relying on Darwin's tolerance would have been untestable here.

Also documents the `from` contract on EffortSyncChange (null means the key was
absent, '' means present with an empty value — a distinction earlier rounds
introduced and then collapsed in the output), adds OpenCode to the docs
paragraph enumerating where the key is omitted under inherit, and records in a
comment that the 'failed' summary reaches only raw mode and does not change the
exit code, which is a CLI-contract change affecting all three branches and is
deliberately not made here.

* fix(#3706): guard the codex read, close the tmp permission window, rename the failure type

Round seven, plus one thing I found myself.

`cmdEffortSyncCodex` still had an unguarded `fs.readFileSync` — a read fault on
one agent exited 1 and aborted the whole sweep. The claude and opencode
branches were both guarded earlier this round and codex was missed, with the
unguarded read sitting ten lines above the chmod block the previous commit did
edit. It now reports read failures the way the OpenCode branch does, and a read
failure flips its summary to `failed` — which write failures did not do there
either, so both are corrected for consistency.

The tmp file was created at the default mode and only tightened afterwards, so
a 0600 agent's contents sat in a 0644 file for the length of the publish. I
measured the window rather than assuming it, then closed it by passing the
mode at creation. The chmod after the write is deliberately RETAINED and
commented: the `mode` option only applies when the file is actually created, so
a leftover tmp from an earlier crashed run would be truncated and reused at its
old mode, and the chmod is what corrects that.

`EffortSyncWriteFailure` is renamed `EffortSyncFileFailure` — it was typing a
`read_failures` array, the same naming-lie the `Codex…` prefix had last round.

Also pins the codex mode preservation with a test. It only writes on a path
that genuinely rewrites the file, so the fixture is an Anthropic-flavoured
model pin the sync strips, and the test asserts the content changed before
checking the mode — otherwise it would pass on a sync that did nothing.

* fix(#3706): guard the claude writes and share one escaping rule

The security sign-off caught a comment of mine that was factually wrong: the
new claude read guard said the failure is folded in "like the write path in
this same loop does", and there was no write guard in that loop. Rather than
correct the sentence, both claude write sites are now guarded the way the read
is — a failed file is skipped, the sweep continues, and the raw summary token
flips to `failed`. The JSON shape stays frozen deliberately, because it is
long-standing and widely consumed; the token is the channel that can carry the
signal without a compatibility risk, which is the reviewer's own suggestion.

That makes all three branches consistent: reads and writes guarded everywhere,
per-file failures degrade instead of aborting, and every branch reports
`failed` rather than `ok` when something did not sync.

`setFrontmatterKeyLine` interpolated its value raw while the install-side
writer quoted through the shared helpers — two writers of the same frontmatter
key disagreeing on escaping, the divergence class this repo requires closed.
They now share one rule. Verified no churn: all six effort levels are plain
scalars and emit byte-identically, with claude's documented minimal-to-low
clamp the only difference in the table, exactly as before.

* fix(#3706): publish claude agent writes atomically too

Both reviewers found this independently, and it is data loss rather than a
reporting gap. The claude branch wrote in place, so `fs.writeFileSync`'s
O_TRUNC meant a post-open fault left the agent file truncated or half-written:
an injected ENOSPC produced an empty file, and under `ulimit -f` a 60000-byte
agent came back as 512 bytes of wrong content. The guard added earlier this
round then counted that destroyed file as `skipped`, which in JSON mode is
indistinguishable from "already in sync" — so a caller would have read the
sweep as clean while an agent on disk was corrupt.

It now publishes the way the codex and opencode branches already do: write to
a tmp file created at the original's masked mode, chmod, then retryRenameSync,
with the tmp unlinked and the agent skipped on any failure. The corrupting case
is gone rather than merely reported, which matters because this branch
deliberately takes no new result key.

I had claimed all three branches were consistent after the previous commit.
That was true for degradation and reporting and not for atomicity; the reviewer
caught the overclaim. It is true now.

Also sorts the claude file list, which the other two branches already did —
readdir order is platform-dependent, so leaving it unsorted made the reported
`changes` ordering differ across machines for identical inputs.

* chore(#3706): backfill the changeset PR number

pr:0 placeholder replaced with the real PR now that gh api returned it.

* test(#3706): kill the frontmatter mutants this change introduced

CI's Stryker frontmatter shard scored 60.58 against a break floor of 62.
The cause is documented in the lane's own config, from #1882: this PR added a
multi-clause predicate to frontmatter.cts and exported the escaper, but the
tests constraining them live in tests/runtime-converters.test.cjs, which that
shard does not run — so every mutant in the new code was uncovered there even
though the behaviour is tested elsewhere.

The fix is assertions that kill real mutants, per the repo's own instruction,
not a lowered floor and not a Stryker disable: scripts/mutation-matrix.cjs is
untouched. Each clause of agentScalarNeedsDoubleQuoting now has a true case AND
a near-miss that must answer the opposite way, so flipping the clause fails a
specific named test — alnum-first against `a-b`, trailing `:` against `foo:bar`,
embedded `: ` against `a:b`, embedded ` #` against `a#b`, the word list against
`yes1`/`nullish`, the numeric forms against `1a`/`0xzz`, the timestamp against
`2026-08-25x`, plus the case-insensitive spellings that pin the `i` flag.
escapeDoubleQuoted is pinned on exact output, including a case constructed so
that escaping in the wrong ORDER yields a different string.

Two of my expectations were wrong and are asserted as the code actually
behaves: `12:99` is NOT quoted, because the sexagesimal alternative never
range-checks minutes and so does not match — which is right, since YAML would
not read it as sexagesimal either; and `20260825` is quoted by the numeric
clause rather than the timestamp one, being a bare integer.

* chore(#3706): ratchet the frontmatter mutation floor to 65

The lane measured 66.67 on PR 3867 after the mutant-killing unit tests landed —
above its pre-change 63.35 baseline, not merely recovered. Step 3 of this
file's own HOW TO UPDATE procedure says to set minScore = floor(measured) - 1
in the same diff, so 62 becomes 65 and the improvement is locked in rather than
left free to slide back.

The ledger of measured scores now records the new measurement, why the shard
broke in the first place (logic added to frontmatter.cts whose only tests lived
in a file this lane does not run — the same trap the #1882 note describes), and
one discrepancy: step 3 also says to update "the matching RATCHET_BASELINE
entry", but no such declaration exists in this file. The name appears only in
that comment, so minScore and the ledger are all there is to update.

* fix(#3706): update RATCHET_BASELINE alongside the raised floor

The ratchet test caught the previous commit: it raised COVERED['frontmatter']
.minScore to 65 without updating the baseline that mirrors it, which is exactly
the mismatch that guard exists to make visible in review.

I had claimed RATCHET_BASELINE did not exist. It does — in
tests/mutation-matrix-ratchet.test.cjs, not in scripts/mutation-matrix.cjs,
which is the only file I searched before concluding it was a stale reference.
The ledger comment is corrected to say where it lives and to record that the
guard caught the error rather than leaving my wrong claim on the record.

* docs(#3706): put the mutation ledger entries back under their own dates

The 2026-08-25 measurement was spliced into the middle of the 2026-06-14 list,
so adr-parser, config-schema, active-workstream-store and core-utils ended up
sitting under the wrong heading and misattributing their measurement dates.
That ledger is what a future change reads to calibrate a floor, so a wrong date
there is not cosmetic. Each measurement is now under the date it was taken.

Also drops the first-person account of my own mistake from the entry — the
factual half (where RATCHET_BASELINE lives, and that it is updated in the same
diff) is what a reader needs; the confession is not.

308c17505c fix(#3840): reject a malformed feature order instead of coercing it (#3851)
* fix(#3840): reject a malformed feature `order` instead of coercing it

`scripts/gen-features.cjs` was the one field validated by coercion rather than
by shape. `Number('')` is 0, and `0x10`, `0b11`, `0o17`, `1e3`, `1.` and `.5`
all coerce to finite numbers, so a fragment declaring a bare `order:` sorted to
position 0 -- ahead of every real feature, in both the body and the generated
table of contents -- with zero violations, a clean `--check` and `--write`
exiting 0. That is a fail-open in a gate whose entire contract is a typed
violation rather than a silent guess.

`order` is now shape-checked against an optionally-signed decimal literal
before coercion, mirroring how ID_RE guards `id`. The finite check stays: the
regex alone would admit a literal long enough to overflow to Infinity.

Surfaced by re-running the feature-implementation directive's design and QA
steps against the code merged in #3845, which shipped without them.

8d8e9ef5eb fix(#3842): stage the emitted-drift-ack sweep so it does not conflict in-flight PRs (#3847)
* fix(#3842): stage the emitted-drift-ack sweep around open PRs

The guard-no-ack-on-next sweep (#3078) deleted every all-spent fragment
under tests/emitted-drift-acks/ unconditionally. When an open PR still
modified the same fragment file, that delete became a modify/delete
conflict on the PR's next merge attempt -- the exact shared-file
conflict fragments were adopted (#2914) to eliminate, reintroduced by
the sweep itself. The first real sweep hit three open, outside-
contributor PRs simultaneously (#3330, #3774, #3648), each with the
swept fragment as its only conflicting path.

assertNoAllSpentFragments now accepts an optional openPrTouchedPaths
set (or the sentinel 'unknown') and partitions all-spent fragments
into "safe to sweep" and "held" -- a held fragment is reported
informationally, never as a failure, and is swept once the touching
PR merges or closes. fetchOpenPrTouchedAckPaths computes the touched
set with a single `gh pr list --json number,files` call. The guard-next
codepath is factored out of main() into the exported, dependency-
injectable runGuardNext() so this wiring is unit-testable without a
real, network-dependent `gh` binary.

The new behavior is strictly opt-in via a --defer-to-open-prs flag,
wired only from the guard-no-ack-on-next job in test.yml (which also
gains pull-requests: read and a GH_TOKEN env for the `gh` call). Every
pre-#3842 caller -- including every existing test -- is unaffected
when the flag is omitted.

CONTRIBUTING.md's "Why fragments, not one file (#2914)" section now
documents the staged-sweep policy so it no longer reads as though
fragments are unconditionally conflict-free once spent.

* fix(#3842): unify the failed-open-PR-check message to one greppable phrase

The remote matrix (commit 4ec4527fb) failed two tests on the fail-closed
path: assertNoAllSpentFragments's 'unknown' sentinel branch described the
failure as "...could not be determined this run...", while runGuardNext's
catch around fetchOpenPrTouchedAckPaths described the same condition as
"open-PR check failed (<err>)". Both messages were genuinely present and
informative (not missing or empty), but they used different wording for
the same fail-closed condition, so there is no single string a human
scanning CI output can search for to find out why nothing got swept.

Unify both sites on "open-PR check unavailable" -- runGuardNext's line
now reads "open-PR check unavailable — <err.message>", and
assertNoAllSpentFragments's holdAll message now leads with "deferred
(open-PR check unavailable): ...". This is a real fix to the fail-safe
path's diagnosability, not a relaxed test assertion: the two now-failing
tests already expected this exact phrase, and the fix makes the code
say what the tests (correctly) expected instead of loosening them to
match arbitrary prior wording.

36375513b9 feat(#3840): generate docs/FEATURES.md from per-feature fragments (#3845)
* feat(#3840): generate docs/FEATURES.md from per-feature fragments

docs/FEATURES.md was hand-maintained, and every feature PR wrote into two
shared mutable cells: the '### N.' heading whose integer was hand-allocated at
authoring time, and the hand-maintained table of contents. Concurrent PRs all
picked the same next integer, and two PRs adding differently numbered features
still collided on the TOC. #3831 was renumbered 165 -> 166 -> 167 -> 168 across
successive rebases, each collision also costing a full matrix verification run
because the sha-keyed pass marker dies with the rebase.

Mechanism: one fragment per feature at docs/features/<slug>.md carrying
id/title/group (and an optional order) in frontmatter, consolidated by
scripts/gen-features.cjs --write|--check into a marker-delimited region of
docs/FEATURES.md that holds BOTH the TOC and every section body. Group headings
and their order are derived too - a group sorts by its lowest-ordered member -
so there is no shared registry to edit either; optional per-group prose lives in
docs/features/_groups/<slug>.md. A contributor adds exactly one new file.
Wired into regen:derived and lint:generated-sync alongside the eight existing
generators, matching gen-adr-index.cjs's CLI shape and typed-REASON reporting.

Migration froze all 168 existing numbers verbatim: identical section set,
identical order, identical bodies. Two defects found in the tree are fixed
inline rather than carried forward - the '## Related' block had been spliced
into the middle of the document, orphaning §142's Reference line, and four
inbound anchors were already broken on next (FEATURES.md#runtime-identity in
two files, and #143-spec-phase-edge-completeness-probe off by one). Since the
repo has no link checker, --check now validates every inbound
FEATURES.md#anchor by resolved target, so that class cannot ship silently
again; locale FEATURES.md files resolve elsewhere and stay out of scope.

* fix(#3840): carry upstream §69 delta into its fragment and harden the generator

Review found section 69 missing '[--strict]' and REQ-STATE-05/06 versus
origin/next. Root cause was a stale base, not extraction loss: those lines
landed in 394bf384b (#3844) AFTER this branch forked at 63abcface, and
'git diff 63abcface origin/next -- docs/FEATURES.md' is exactly that hunk.
Merging origin/next auto-applied the hunk into the GENERATED region, which
--check immediately reported as stale; the delta is now carried in
docs/features/statemd-consistency-gates.md and regenerated from there.

--write is now fail-closed. It previously rendered the region even with
violations outstanding, warning only on stderr and exiting 0, so a
'--write && git commit' chain could commit a FEATURES.md carrying two
colliding sections. It now refuses and exits 1; --force is the explicit
override and says so in the report. The test that pinned the old behavior now
pins the refusal, plus the --force override and its scoping.

Marker forgery is rejected at two layers. A fragment body containing
'<!-- FEATURES:START' or '<!-- FEATURES:END' is a typed
body_forges_region_marker violation (fragments and group notes alike), and
spliceIntoFeatures anchors the end boundary with lastIndexOf instead of
indexOf, so a marker that reaches the document by any other route can only
make the generated region grow, never shrink. Matching is on marker PREFIXES,
so a decorated variant comment cannot slip past.

Symlinked corpus entries are refused with a typed dirent_not_regular_file
rather than read. A fork PR could otherwise commit docs/features/evil.md as a
symlink to any readable path and have the generator inline those bytes into
the committed docs/FEATURES.md on the next regen.

Equivalence re-verified with a method that cannot cancel out. The first
check extracted both operands with the same body-normalising helper, so
anything that helper dropped was dropped on both sides. The replacement runs
two independent passes: a global content-line multiset diff with no
per-section logic at all (0 gained, 19 lost, all 19 the stale hand-written
mini-TOC links this change deliberately deletes), and a per-section
byte-exact body diff carrying a coverage assertion that fails loudly per file
when the extractor accounts for fewer lines than the file contains. That
assertion caught two blind spots in the checker itself. 168/168 sections
present, order identical, one intended body difference (§142 regains the
Reference line orphaned by the misplaced '## Related' block).

63abcface9 feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools (#3831)
* feat(#3146): resolve gsd_run so workflows cannot reach a foreign gsd-tools

The predecessor package get-shit-done-cc publishes a colliding gsd-tools bin whose phases.clear DELETES where this package's ARCHIVES, and both print success-shaped output against a gitignored .planning/ -- which is how #3129 cost a user 43 phase directories with no error and nothing recoverable from git.

The launcher's PATH branch now resolves gsd_run, published only by this package and self-locating via its own symlink chain to the sibling shim, instead of the colliding gsd-tools. A foreign handler becomes unreachable from PATH, and when no gsd_run is reachable the resolver fails closed rather than falling back -- that fallback was the vulnerability. This is smaller than the branch it replaces, which matters: the preamble is inlined into 113 shipped files and agents/gsd-verifier.md sits 2 bytes under a red-line size cap.

unset -f gsd_run leads the preamble so a re-source is idempotent. Without it, command -v finds the shell function, returns a bare name, and the resolver falls through to an exit 1 that kills a sourced caller's shell.

Adds gsd-tools runtime-identity, a manual diagnostic reporting this runtime's package coordinates over the baked package-identity (#498) and readHostVersion, with a strict total classifier: only a JSON object with an exact packageName verifies, since JSON.parse admits 0/"str"/[]/null/true.

An inlined identity assertion was built and reviewed first, then withdrawn -- it breaks five frozen size ceilings and no assertion fits in 2 bytes.

Closes #3146

* fix(#3146): stop sync:launcher relocating a deliberate preamble placement

Pre-existing defect, surfaced by this PR because sync is a no-op unless the snippet content actually changes. transformFile inserts the preamble into the first block that CALLS gsd_run, but gsd-core/workflows/explore.md deliberately places it in a bootstrap-only block that DEFINES gsd_run without calling it -- its own comment explains why: declining the research offer must not leave Step 5's commit call unbootstrapped. Stripping empties that block of calls, so the preamble migrated forward and broke the define-before-use invariant tests/explore-command.test.cjs pins.

Reproduced on a pristine origin/next checkout with the base snippet and base file, so this was not introduced here. The insertion target now honours a block that already carried the preamble, falling back to the first calling block for files that have none yet. Adds a behavioral regression test over a two-block fixture.

Also updates three runtime-launcher-parity tests that pinned the removed PATH fallback to gsd-tools. Their intent is preserved -- the PATH stub is renamed gsd_run so it is reachable by the new resolver, and the RUNTIME_DIR-wins test still asserts the stub is never invoked. Fixture shebangs move to an absolute /bin/sh, because the fixture PATH is deliberately restricted and #!/usr/bin/env sh could not resolve.

* docs(#3146): document the FEATURES.md section-numbering practice

The monotonically increasing section number in docs/FEATURES.md is the most frequent merge-conflict source in this repo, and it has TWO conflict cells, not one: the ### N. heading and the hand-maintained table of contents. Two PRs adding differently numbered features still collide on the TOC, so renumbering alone does not make a branch safe. This branch alone was renumbered 165 -> 166 -> 167 -> 168 across successive rebases.

Adds a CONTRIBUTING section stating the practice: allocate the number last, never pre-emptively renumber, take max+1 after a rebase and update the TOC in the same commit, and never renumber someone else's section. Fork contributors are told explicitly they may leave the number to a maintainer at merge rather than chasing the counter. Agents are told to lease the allocation and to include the file in their published touched set.

Records the durable fix as planned rather than pretending it exists: FEATURES.md should be generated from per-feature fragments the way CHANGELOG.md is generated from .changeset/, and the way tests/emitted-drift-acks/ works (#2914).

Also renumbers this branch's own section to 168, leaving 167 to the PR already in flight.

596540f864 feat(#3227): publish machine-readable state contract at step boundaries (#3824)
* feat(#3227): publish machine-readable state contract at step boundaries

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

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

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

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

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

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

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

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

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

a84f756303 fix(#3078): sweep all-spent ack fragments on next, name the collision remedy (#3823)
* fix(#3078): sweep all-spent ack fragments on next, name the collision remedy

`guard-no-ack-on-next` only ever watched the legacy tests/emitted-drift-ack.json.
#2914 exempted the fragment directory on the premise that a persisting fragment
"cannot conflict with any other PR". Fragments do not share a FILE, but they do
share a PATH KEY SPACE, and a path claimed by two sources is a hard failure in
the same script -- so a fully-spent fragment on next owns keys it can no longer
gate, and the next PR to grow one of those paths can declare it neither there
(spent) nor in its own fragment (duplicate). Measured at the sweep: 45 fragments
owning 403 paths, up from 13/272 at triage 19 days earlier.

- `assertNoAllSpentFragments` fails a fragment only when EVERY surviving entry is
  spent against the copy at HEAD^, so a partially spent fragment -- and the
  re-arm-by-appending route #2639/#2993 ship on -- keeps working.
- `ackProse` duplicates the gate's zero-width/whitespace stripping across the
  scripts-ship/tests-do-not line, bounded by a prose-parity test.
- The guard job's checkout takes fetch-depth: 2; at depth 1 HEAD^ is absent and
  every fragment reads as brand-new, i.e. the guard passes vacuously.
- The duplicate-ack error now names both resolutions, since the guard is
  post-merge by design and cannot stop the colliding PR.
- All 45 spent fragments deleted, 0000-legacy-migration.json included, and the
  three tests that pinned its permanence corrected.

Verification is the remote runner (gsd-test), not a local suite.

Closes #3078

* fix(#3078): make the prose-parity test two-sided, cover the git seam, base on the pre-push tip

Three review findings, all fixed:

- The parity test was a tautology: it checked ACK_INVISIBLE against a
  hardcoded list matching its own definition, never against the gate. The
  gate's INVISIBLE and its reason normalizer (hoisted out of diffEmitted as
  normalizeAckReason) are now exported for that sole purpose, and the test
  sweeps 0x00-0xFFFF against both surfaces. Mutation-checked: adding a
  codepoint to one side and not the other now fails.
- resolveBaseRef, readFragmentAtRef and assertUsableBaseRef had zero direct
  coverage -- the tests reimplemented the git reads in a local helper, so the
  ls-tree-vs-show discrimination, the root-commit fallback and the
  option-injection guard were never executed. All are exported and tested
  against real temp repositories now, plus an end-to-end --base-ref subprocess.
- HEAD^ is not 'the state of next before this push'. The default branch allows
  REBASE merges, so one push can carry N commits, and a 2-commit rebase-merge
  whose first commit adds a fragment would be told to git rm it on the very
  push that introduced it. CI now passes github.event.before via --base-ref and
  fetches it explicitly; HEAD^ remains only the local fallback.

Also adds the safe.directory guard every other git call in this repo carries
(#2767), and stops naming the deleted migration fragment by filename in
CONTEXT.md, which tripped lint-removed-but-needed.

Refs #3078

* fix(#3078): keep the fragment directory alive after the sweep empties it

Sweeping every fragment leaves the directory untracked, and check-glossary-refs
then fails: CONTEXT.md references tests/emitted-drift-acks, which no longer
exists. The empty directory IS the intended steady state, so it has to survive
its own remedy.

Adds tests/emitted-drift-acks/README.md documenting the create/use/delete
lifecycle where a contributor actually meets it, matching the existing
tests/qa/smell-acks/README.md precedent. Every reader filters on .json, so the
README is invisible to the gate.

Also sweeps #3809's ack fragment, which the rebase onto origin/next brought in
and the new guard immediately reported as all-spent -- its own remedy applied.

Refs #3078

* fix(#3078): guard the added tests' git calls, drop a second fragment-existence pin

Both defects surfaced by the remote runner (linux-node24, 4/37445 failed).

- The new --base-ref E2E test ran `git rev-parse HEAD` against the checkout
  without the #2767 safe.directory guard. The runner mounts the repo at a path
  owned by another uid, so git refused every operation there with 'detected
  dubious ownership'. Every git call the new tests make now names its own
  specific directory as safe, via one local helper, mirroring safeDirArgs in
  helpers/emitted-runtime.cjs.
- tests/agent-tracked-source-rule.test.cjs pinned the existence and contents of
  the 3645 and 3409 ack fragments. That is a merged PR's paperwork, not live
  behavior: once the growth is in next's baseline the acks are spent and this
  PR's guard sweeps them. The third assertion pinned the hand-appended
  workaround for the exact collision #3078 removes. Deleted; #3645's real
  protection is the two behavioral tests above it, untouched.

Also restores #3809's ack fragment, which merged one commit before this branch.
Deleting an ack in the same window as its introducing PR races any consumer
whose baseline predates it -- the runner's container proved it, resolving
origin/next to 8ed105c8a where the file is still 13847. The backlog sweep is
this PR's scope; that fragment is left for the guard's own first run.

Adds the rule to the fragment README so the class stops recurring.

Refs #3078

* test(#3078): derive the E2E guard expectation from the fragment inventory

The --base-ref E2E test asserted exit 0 while passing the checkout's own HEAD
as the base ref. HEAD-as-base makes every present fragment byte-identical to
itself, so all of them are trivially all-spent and the guard correctly exits 1.
The test only ever passed because the directory happened to be empty when it
was written; restoring #3809's fragment made it fail. The script was right and
the test was wrong.

The degenerate base ref is kept deliberately -- it is what makes 'spent'
trivially true and therefore deterministic -- but the expectation is now
derived from listFragmentFiles() at runtime: zero fragments means exit 0 and
the no-survivors line, N fragments means exit 1 with every name and its git rm.
Proven state-independent by running the suite with the fragment present, with
the directory emptied, and with it restored.

The option-shaped --base-ref rejection is split into its own test, unchanged.

107eb8c1d9 feat(#3753): run docs guards on the PR that changes the docs they read (#3787)
A PR whose diff is entirely under docs/ runs zero tests, so a guard whose INPUT
is shipped prose cannot protect the PR lane of the diffs it exists to check. Its
only firing opportunity is after merge, on the shared branch -- which is how next
went red on dacae9273 while the PR that caused it (#3746) was green on every
check.

The docs-lint job in .github/workflows/docs-required.yml -- an ALREADY-REQUIRED
context -- now selects and runs the docs guards that read the specific docs files
the PR changed.

  scripts/docs-guard-registry.cjs    test file -> the docs paths it reads (63)
  scripts/select-docs-guards.cjs     pure (changedPaths, registry) -> test files
  scripts/lint-docs-guard-registration.cjs   drift guard, wired into lint:ci

scripts/ci-test-scope.cjs is NOT touched -- `git diff origin/next --` on it is
empty -- so #764's saving stands and its 21 pinning tests are untouched.

Selection: exact path; trailing-slash directory prefix (boundary-checked --
docs/adrenaline.md does NOT match docs/adr/, which a naive startsWith gets
wrong); and '*' for the 6 entries that walk docs/ generally or read a computed
path. Unknown maps to '*' -- guessing narrow is how a guard silently stops
running. Measured: a typo fix selects 6 of 63; docs/AGENTS.md selects 12;
docs/COMMANDS.md selects 18.

Four things this got wrong first, each found by an independent reviewer or by
probe, and each having been asserted safe in a comment:

1. The registry started as a RULE in ci-test-scope.cjs's RULES, on the theory
   that classify()'s !codeChanged normalization made it inert. True for
   docs-ONLY diffs; false for MIXED docs+code diffs, where codeChanged is true
   and the normalization never runs:

     node scripts/ci-test-scope.cjs --files "docs/a.md src/semver.cts"
       with the RULE:  25 targeted_tests
       origin/next:     3 targeted_tests

   Category error: RULES is the scoped lane's input; a docs-guard registry is a
   lane manifest for a consumer that never calls classify(). Extracted; pinned
   by value.

2. The second attempt was a dedicated workflow with paths: [docs/**]. Such a
   workflow never reports on a non-docs PR, so it can never be a required
   context without hanging every non-docs PR -- and a non-required check does not
   block a merge, so the guard would have been advisory and #3753 unfixed.
   docs-required.yml already has no paths: filter, already supplies the required
   docs-lint context, already computes docs_changed, and already ran one docs
   guard gated on it. Generalizing that step needs no ruleset edit at all.

3. The registry and the drift lint were built from ONE path-segment heuristic, so
   both were blind identically -- and blind at the guard that motivated the issue.
   The reader-call regex required a character BEFORE its keyword, so a callee
   named exactly read( / load( / parse( / doc( / file( / content( could never
   match; and only an INLINE path.join(ROOT,'docs','X.md') argument was caught,
   missing the two-step-via-variable form -- the MAJORITY spelling -- plus
   template literals and concatenation. Detector 1 fired on 14 of ~450 files, so
   35 genuine guards sat unregistered while the lint reported 0 violations,
   including cursor-reviewer (reads docs/COMMANDS.md, asserts
   .includes('--cursor')) and inventory-headings-countfree. The "accepted blind
   spot" this shipped with was the common case, not a fringe.

4. With detection fixed the true population is 115 files: 63 genuine guards, 52
   incidental. Running all 63 in a REQUIRED check on a one-line typo fix is the
   cost #764 exists to avoid -- install.test.cjs is 7840 lines and reads exactly
   one docs file, docs/AGENTS.md, for its frontmatter. Dropping it reproduces the
   bug; running it for a typo elsewhere is waste. Hence the map.

Then a second review round found six more, all fixed here:

- fragment-single-edit-propagation.install.test.cjs was EXEMPTED as
  "overlay fixture only". False: it reads the real docs/registries/eos.json and
  asserts on a registry entry name, and reads the real ADR-0001 and asserts its
  H1. A docs-only PR touching either would have gone green and red next -- #3753
  shipping again, from inside the fix for it. Now registered against both paths,
  and all 52 remaining exemptions were re-audited one by one.
- The SUITES-collision guard compared RAW registry keys, but run-tests.cjs strips
  a leading `tests/` BEFORE its suite check. So it caught 'all' and missed
  'tests/all' -- the only spelling that can actually occur, since every key
  carries the prefix. One typo would have run all 824 test files inside the
  required job. Now normalized the same way run-tests.cjs normalizes.
- The lint failed OPEN on an unreadable tests dir or candidate file: 0 violations,
  ok:true. A guard that cannot read its input must never report success.
- The exemption ratchet gated identity only, so a baselined file that later
  STARTED asserting on shipped docs stayed exempt silently -- 52 permanently blind
  files. The baseline now fingerprints the docs paths each exempted file
  references and fails when that set changes, naming what changed.
- The exemption marker was still honored inside a multi-line template literal in
  the header window. The scanner now tracks template-literal and block-comment
  state.
- `git diff --name-only | grep '^docs/'` silently dropped C-quoted non-ASCII docs
  paths, making docs_changed=false a green zero-guard check. Both call sites now
  pass -c core.quotepath=false.
- The run step was gated on hashFiles(), which a force-committed
  .docs-guard-tests.txt would satisfy. The step now rm -f's both scratch files
  first and gates on an output it sets itself.

Three empty states, deliberately distinct, because conflating them rebuilds
#3753: an empty or malformed registry HARD-FAILS; docs changed with no guard
covering them logs and skips; no docs change is already gated. The middle state
must never be expressed as an empty --files-from, which prints `no tests in suite
"all"` and exits 0 -- a green check that guarded nothing. With the current
registry that state is unreachable, because the six '*' entries always match;
the branch is kept as defensive handling for a future registry and says so.

timeout-minutes: 15 bounds the required job against a hanging fork-supplied test;
it had none. npm ci was added because the job never installed dependencies -- the
previous single-file step got away without it, the registry does not.

docs/contributing/docs-guard-registration.md documents the rule, following its
sibling cross-platform-portability-rules.md, and CONTRIBUTING.md's CI Test
Quality Checks table links to it. It is also load-bearing: without a docs/ file
in the diff this PR would not have triggered its own lane, shipping an
unexercised change to a required check.

One unrelated fix, included because this PR surfaced it and CLAUDE.md forbids
deferring a defect found while working. On this branch's first CI run,
`full test (windows-latest, 24, shard 3/3)` was CANCELLED at exactly 30 minutes;
tests were still passing 0.8s before the cancel, so it is a wall-clock timeout,
not a hang, and a cancelled job reddens `Required tests`.

The cause is not this PR's test file, which costs ~60ms. Shard composition is
unstable: adding ONE file to the unit suite reshuffled 115 of 268 files between
shards, and shard 3 drew a heavier mix. Underneath that is a real pre-existing
defect. tests/ci-test-job-timeout-budget.test.cjs requires every lane's budget to
be >= 1.5x its MEASURED cost -- "a lane that got slower must be re-budgeted, not
excused" -- and its test-full entry recorded 19m from a windows-22 shard. That is
stale. Measured on `next` with none of this PR's changes present: 26m18s (run
32614439702, windows-latest/24 shard 3/3), 23m36s and 23m17s on shard 2/3. So the
lane costs ~26m and the 30-minute cap carried 1.14x headroom, not 1.5x. The gate
had been out of compliance with its own rule; this PR was merely the file
addition that reshuffled shard 3 past the cliff.

Fixed as that file prescribes: measuredMinutes 19 -> 27 with fresh evidence, and
test-full timeout-minutes 30 -> 45. The rule's minimum for 27m is 41; 45 is
deliberately above it because the reshuffle means per-shard worst case moves run
to run, and a budget pinned to the exact minimum would be re-breached by the next
test file anyone adds. Only that one job's timeout changed; test.yml's scope,
matrix and steps are untouched, so #764's saving is unaffected.

Raising that cap let the Windows shard finish (28m45s, inside 45) and uncovered
a real failure the 30-minute cancel had been masking:
`new quick-task branch branches off origin/main (#2916)` died with
`outcome=timed_out exitCode=null`, SIGTERM, at the 15000ms bound.

tests/quick-branching.test.cjs:149 `runStep` runs a `#!/usr/bin/env bash` script
executing MULTIPLE git commands, but was bound to GIT_TIMEOUT_MS (15000) -- the
norm for a SINGLE git plumbing call. tests/helpers/timeouts.cjs already documents
this exact failure and exists to fix it: HOOK_FANOUT_TIMEOUT_MS was created after
PR #3285 recorded "outcome=timed_out exitCode=null at exactly the 15000ms probe
bound while every other lane passed the same commit", and calls that "a bound
sized for the wrong class, not a slow machine". Our failure is that case
verbatim, so both sites move to the class norm rather than to a bigger number.

The same class also failed on `next` itself 21 hours earlier -- run 32608945654,
windows-latest/24 shard 1/3, `plan touching only src/ in a submodule project
keeps worktree isolation ENABLED` -- where tests/worktree-safety.test.cjs:5845
`runGate` fans out to `git config --file .gitmodules` under a hardcoded 30000.
Fixed too, since it is a defect in the tree regardless of which branch surfaced
it.

A survey of the whole tests/ tree found the same class-mismatch at further
bash fan-out sites bound under 60000ms, and the maintainer approved sweeping
them rather than leaving them latent to surface the same way one at a time. 16
fan-out sites across 16 files now use the class norm.

The sweep is class-correctness, not raising numbers until things pass. Sites
were moved ONLY where the bash body demonstrably spawns something (git, node,
npm, a CLI); self-contained shell snippets were left where they are, and are
listed as deliberately unchanged: pure if/printf bodies (copilot-install), pure
array/case builtins (code-review-pipeline-regression:638), a documented
pure-shell gsd_run stub (host-integration), single-process hook calls
(workflow-guard:222/271/302), and a deliberately tight 5000ms fast-check hook
(gsd-write-guard.property). Nothing was lowered. process-seam.test.cjs:513
(literal 300) is untouched on purpose -- it tests timeout BEHAVIOR, so raising
it would destroy what it asserts.

Shared file-level constants were the trap here, and were handled per file rather
than by redefinition: GIT_TIMEOUT_MS has ~15 users in git-base-branch and only 1
is a fan-out; WORKTREE_TIMEOUT_MS has 16 users in worktree.test.cjs and 3 are;
PROBE_TIMEOUT_MS has several in three more files. In each the CALL SITE was
changed and the constant left alone, so no single-plumbing-call site silently
inherited a 60s bound. The one exception is hooks-opt-in.test.cjs, where
HOOK_TIMEOUT_MS has exactly one consumer -- spawnHook, the fan-out itself -- so
redefining it is identical in effect and reads better.

Only two of these sites have actually been observed failing. The rest cite that
shared class and those two run ids rather than inventing evidence of their own.

004e9dd741 fix(#3007): resolve Codex reasoning effort per model and make every clamp visible (#3765)
* test(#3007): failing-first suite for per-model Codex effort capability

RED by construction. Binds to behavior renderEffortForRuntime does not yet
have: an optional third `model` argument, a per-model advertised-level table,
`max` passing through instead of clamping to `xhigh`, `minimal` clamping to
`low`, `ultra` rejected outright, and clamp visibility (`requested`/`clamped`/
`reason`) so a downgrade is legible from resolver output rather than silent.

Two of these pin defects that exist on next today:

- `max` is discarded. Both Codex models whose catalog entries are retrievable
  (sol, luna) advertise `max`; GSD clamps it to `xhigh` and reports nothing.
- `minimal` is emitted to a model that refuses it. providerPresets.openai.
  haiku.low pairs gpt-5.6-luna with reasoning_effort "minimal", and luna's
  advertised floor is `low`. GSD is sending a value into a document Codex
  itself validates. The parity test is what pins that fixed, and it names the
  offending path/model/effort when it trips.

Also corrects tests/model-resolver.test.cjs:351, which asserted
renderEffortForRuntime('codex','max').value === 'xhigh' -- the defect pinned as
though it were a contract. ADR-443 recorded "Codex has no max" as fact and it
was true when written; Codex has since added both `max` and `ultra`. That is a
stale premise, so the assertion is corrected here rather than worked around.

The property test asserts the invariant the whole change exists for: a rendered
effort is always a level the target model actually advertises, or an explicit
rejection. There is no third outcome.

* fix(#3007): resolve Codex effort per model, and make every clamp visible

Codex declares supported_reasoning_levels per MODEL and validates against it,
so a single per-runtime capability set cannot be right for all of them. GSD's
was wrong in both directions at once.

`max` reaches Codex now. ADR-443 recorded "Codex has no max" as fact and clamped
max -> xhigh on that basis; it was accurate when written, and Codex has since
added both `max` and `ultra`. Every Codex model whose catalog entry is
retrievable advertises `max`, so the clamp was discarding a level the provider
supports, silently, on the most-used path.

`minimal` stops reaching Codex. No Codex model advertises it -- both retrievable
entries floor at `low` -- yet providerPresets.openai.haiku.low paired
gpt-5.6-luna with reasoning_effort "minimal". GSD was writing a value the
receiver validates and refuses into a file the receiver reads. Being
unconservative in what you send is the half of Postel's rule with no defensible
reading, so that preset is corrected and a parity test pins it.

`ultra` is refused rather than laddered. Codex's own catalog calls it "Maximum
reasoning with automatic task delegation": at ultra, effective_multi_agent_mode
returns Proactive and Codex spawns sub-agents on its own initiative, underneath
GSD's orchestration rather than inside it (#2167). It is a mode switch, not a
reasoning depth, so it is not added to the universal ladder -- which stays
provider-agnostic by ADR-443's design -- and it is rejected even for
gpt-5.6-sol, which does advertise it. Clamping it down to `max` was considered
and rejected: that silently discards what the user actually asked for.

Clamping is now visible. RenderedEffort carries requested/clamped/reason and
resolve-execution surfaces them. The previous table clamped correctly but
invisibly, so a user asking for `max` on Codex had no way to find out they were
getting `xhigh` -- exactly the failure mode the robustness principle's modern
critique warns about, and why "be liberal" has to mean "liberal and loud".

Also closes a latent trap found while reviewing the implementation: the clamp-up
loop walks the ladder upward, and for a future model advertising `ultra` but not
`max` it would have selected `ultra` as the clamp target -- re-entering by the
back door the mode the rejection above exists to keep out. A clamp may never
produce a value that a direct request for that value would refuse. Unreachable
with today's catalog, which is why no test caught it; a test now asserts the
invariant directly.

Signature stability is preserved: the third `model` argument is optional and the
two-argument form still resolves, against the family baseline. That form's
BEHAVIOR does change for `max` and `minimal`, and it must -- keeping the old
answer would have fixed the defect only where a model happened to be threaded
through and left it live everywhere else.

tests/model-resolver.test.cjs:351 asserted the defect as if it were a contract
and is corrected here rather than worked around.

* fix(#3007): close every review finding on the Codex effort alignment

Two isolated reviewers, correctness and security. Both found the same two
blockers, and the per-model work was inert on every surface that matters until
this commit.

BLOCKER — resolve-execution never passed the model and discarded the clamp.
cmdResolveExecution called the two-argument form and emitted only
effort_rendered/effort_param/effort_propagation, so the per-model table was
unreachable from production code (tests were its only caller) and requested/
clamped/reason were computed and thrown away. Requested outcome 3 names "the
effective rendered effort in resolver output" specifically, so the feature was
unmet on the exact surface the issue asks for. Now passes the resolved model and
emits effort_requested / effort_clamped / effort_clamp_reason, flat, matching the
existing key convention rather than introducing a nested object.

BLOCKER — the docs described output that did not exist. CONFIGURATION.md showed
a nested {"effort": ...} sample; the real result is flat and those keys were
absent entirely. A reference doc asserting a JSON path a reader can copy is worse
than no doc. Corrected against the actual emitted key set.

MAJOR — the argv channel still shipped both original defects. EFFORT_ARGV.codex
kept minimal in its supported set and still clamped max down to xhigh, so the
invocation-time and install-time channels disagreed about the same runtime's
capability: --host codex with max emitted xhigh while the generated TOML said
max. This is the repo's documented generative-fix-divergence class, so both
tables now cross-reference each other and a parity test fails if they ever
diverge again.

MAJOR — malformed catalog data failed OPEN and could crash the CLI. A null
_baseline became an EMPTY Set that is nonetheless truthy, so the nullish fallback
never fired and every effort rendered as null. And a non-array value made the Set
constructor throw at module load — model-catalog.cjs is required across the whole
CLI, so one bad JSON value killed every command, not just codex effort. Guarded
on size and filtered to array values; both degrade to the hardcoded baseline.

MAJOR — value widened to a nullable string with two consumers left behind.
runtime-artifact-conversion passed it straight into injectEffortFrontmatter (a
null effort key in generated frontmatter); install-effort-resolver still declared
a non-nullable return, a structural lie that silently defeated null checking.
Both corrected, both omitting the key on null — the same posture as 'inherit',
where omission means "follow the host default".

MAJOR — the per-model table is inert today, and the docs now say so. All three
shipped models advertise the same usable range and ultra (sol's only
differentiator) is rejected for every model, so no observable output differs by
model. The table stays because Codex declares capability per model and the sets
are free to diverge — a single per-runtime assumption is precisely what went
stale and produced this issue — but overselling it as a visible per-model feature
would have been the same class of error as the doc blocker above.

Tests: three passed under a full revert and are strengthened rather than deleted,
since each guards a real contract (#3533's inherit rule, the undeclared-host
rule, off-ladder handling) — they now also assert the clamp-visibility fields,
which only exist after this change. The fast-check property is kept for its
shrinking, and a deterministic nested loop over the full cross-product now sits
beside it so coverage is exhaustive rather than sampled.

Also folded in earlier: bin/install.js generated the Codex TOML with the two-arg
form and would have written a literal null reasoning effort on the ultra path;
CONTEXT.md's Model Catalog Module glossary entry now records CODEX_MODEL_EFFORT.
The installer defect was found by the co-change gate, not by a reviewer —
install.js is a historical co-change partner of model-catalog.cts that this diff
had not touched.

* test(#3007): correct assertions that pinned Codex's stale effort premise

Thirteen pre-existing tests encoded "Codex has no max" as fact and failed on the
shipped commit. Every one is a stale pin, not a defect: each was probed against
the built module before its expectation was changed, and none failed for a
reason other than this premise correction.

Kept as its own commit per CONTRIBUTING — a test-fixture correction made stale
by a production change must not ride inside another commit, because the
release-sdk hotfix cherry-pick filter routes by subject prefix and a correction
buried under the wrong prefix ships a half-state (v1.42.3, #3621).

The most valuable one was tests/model-resolver.test.cjs's cross-provider
validity invariant, which hardcoded the Codex enum as
`minimal|low|medium|high|xhigh` and failed with "real API would 400". That
message is now false in both directions: Codex accepts `max`, and rejects
`minimal`, which no model advertises. The enum is corrected to
`low|medium|high|xhigh|max` and the guard is kept intact — it is exactly the
"would the real API refuse this" check worth having, and it was right to fail
here. It simply carried the stale fact in its own fixture.

Test NAMES were corrected alongside their assertions wherever the name asserted
the old behavior — "max is Anthropic-only", "max clamps to xhigh", "minimal
passthrough". A renamed test that still claims the old thing is worse than a
failing one, and a green test whose name states a falsehood is how the next
reader inherits the wrong premise.

Both channels are covered: install-time (renderEffortForRuntime, and the
generated .toml in install-runtime-artifacts) and invocation-time argv
(effort-surface-axis). They were deliberately brought into agreement in this
change, so their assertions had to move together.

Each site carries a #3007 comment recording that Codex gained max/ultra and that
capability is declared per model, so a future reader can tell this was a
deliberate premise correction rather than a test bent to fit an implementation.

* test(#3007): separate the effort-precedence case from the clamp case

The previous stale-assertion pass over-corrected one test. It saw
`effort: { default: 'max' }` on codex expecting `effort_rendered: 'xhigh'`,
assumed the xhigh came from the max→xhigh clamp #3007 removes, renamed it to
"max passes through" and changed the expectation to `max`. The remote runner
disagreed.

Reproduced against the real CLI: with that config and `gsd-planner`, the
resolver emits `effort: "xhigh"`, `effort_requested: "xhigh"`,
`effort_clamped: false`. The xhigh is produced by effort-resolution PRECEDENCE —
gsd-planner is heavy/opus tier and its routing-tier default outranks
`effort.default` — so `max` never reaches the renderer at all. The test says
nothing about clamping and never did; it only looked like a clamp pin because
both mechanisms happened to yield the same string.

Restored to `xhigh` and renamed to say what it actually tests. It now also
asserts `effort_clamped === false` and `effort_requested === 'xhigh'`, which is
what makes it impossible to mistake for a clamp pin again: those two fields prove
the value is what the resolver produced rather than something the renderer
downgraded. Before #3007 there was no way to tell the two apart from the output —
which is precisely why the previous pass could not tell them apart either.

Added the test that was actually missing: `effort.agent_overrides`, which
outranks the tier default, so the requested level genuinely reaches the renderer
and `max` survives to `effort_rendered` end-to-end through the real CLI. Verified
by probe before asserting.

One test now pins the precedence rule and the other pins the #3007 behavior, and
neither can be read as the other. That the clamp-visibility fields are what
resolved this is a small argument for having added them.

* chore(#3007): backfill changeset pr number to 3765

* test(#3007): put model-catalog under the mutation gate

The Stryker shard showed as `skipping` on this PR despite the diff rewriting
model-catalog's effort logic. That was legitimate, not a detection bug:
`model-catalog` was never in scripts/mutation-matrix.cjs's COVERED map, so the
whole module — including everything #3007 touches — sat entirely outside
mutation scoring with has_work "false".

Registered, with a dedicated spawn-free surface. tests/model-catalog.unit.test.cjs
is new: 44 in-process tests, no runGsdTools, no child process, no filesystem, no
temp dirs. That shape is not stylistic — it is the #2790 precedent this file
already documents. Stryker's command runner treats a whole `node --test <file>`
invocation as ONE test costing whatever its slowest case costs, and re-runs it
per mutant, so pointing a shard at tests/model-resolver.test.cjs (which uses
runGsdTools throughout) would reproduce exactly the 15-minute shard-cap
cancellation #2790 hit. The integration file is unaffected and keeps running in
full in the normal test job.

Coverage spans the module rather than only the diff, because the score is
measured over the whole file: effort rendering across every model and ladder
level in both channels, the prototype-chain host guard, the exported enums and
maps, isAnthropicFlavoredModel's provider namespacings, the profile projections,
nextTier, and mergeEffortTierDefaults. The last two were nearly left out and are
worth naming — every uncovered exported function is score given away, and
mergeEffortTierDefaults turned out to have a genuinely interesting contract
(#3531: a partial override merges over the built-ins rather than replacing them,
and isValid gates the VALUE, not the tier name, so an unknown tier key is still
merged in). Every expectation was probed against the built module before being
asserted.

minScore is 1 and that is a PLACEHOLDER, flagged as such in the registry comment.
Floors in this repo are measured, not chosen — the existing entries sit at 94, 75
and 56 — and they can only be measured in CI, because mutation shards run
`node --test`, which is hard-blocked locally. The first CI run on this branch
reports the real number and the floor gets ratcheted to it before merge. A
placeholder of 1 reaching `next` would make the gate decorative: it would pass
whether or not a single mutant is ever killed.

Note the target is "never regress from measured", not a fixed 80 — planning-inspect
sits at 56 and is documented as an accepted ratchet candidate.

* test(#3007): bootstrap model-catalog's mutation floor legally

The placeholder floor was structurally illegal and the remote run said so.
tests/mutation-matrix-ratchet.test.cjs guards the guard: every COVERED module
must carry a matching RATCHET_BASELINE entry in the same diff, minScore must
EQUAL that baseline, and it must be at least 50. `minScore: 1` failed all three.
That is the ratchet working exactly as intended — a floor nobody can satisfy
accidentally is the point of it.

Bootstrapped at 50 in both places. Fifty is not a measured score and the comment
says so plainly: it is the minimum the guard permits, and it coincides with
Stryker's own configured `break` threshold, so it is the lowest legal starting
point for a module that has never been measured. It still must be ratcheted to
floor(measured) - 1 before this PR merges.

Also corrected a real defect in the file's own instructions. "HOW TO UPDATE"
step 1 read "Run the per-module Stryker shard locally" — which cannot be done
here, and which the same file contradicts eighty lines further down, where the
#2790 scores are recorded as "not a local run; mutation shards run `node --test`,
hard-blocked in this repo's local environment". stryker.config.mjs confirms the
command runner invokes `node --test` once per mutant, and
.claude/hooks/block-local-node-test.sh denies exactly that. So the documented
first step sends the next contributor at a wall. Rewritten to describe the path
that works — push, read the measured score off the CI shard, then set the floor
and its baseline together in one diff — and to say why local measurement is not
available, so nobody rediscovers it the slow way. GOODHART SAFETY is untouched.

The two-step is inherent to the environment rather than a shortcut: a floor
cannot be measured before the first CI run exists, and the guard rightly refuses
to accept an unmeasured one below its minimum.

* test(#3007): ratchet model-catalog's mutation floor to its measured score

The shard ran in CI and reported 59.62% — 248 mutants killed, 168 survived, no
timeouts, no errors (run 32605073352, job 97108869486). Floor set to 58 per this
file's own rule, minScore = floor(measured) - 1, which is the same arithmetic
every sibling entry used: 57.03 to 56, 76.58 to 75, 95.65 to 94.

Both halves moved together, because the ratchet guard asserts minScore equals its
RATCHET_BASELINE entry and would reject them drifting apart.

The spawn-free unit surface is vindicated by the clock: 57 seconds, against a
15-minute shard cap and a 9m46s frontmatter shard in the same run. That was the
whole reason for creating tests/model-catalog.unit.test.cjs rather than pointing
the shard at tests/model-resolver.test.cjs — #2790 recorded shards being
CANCELLED at that cap when they targeted a runGsdTools-heavy integration file.

The registry comment is rewritten rather than deleted. It previously warned that
the floor was provisional and must not ship that way; leaving that text next to a
measured floor would make the file lie in the other direction. It now records the
measurement the way the sibling entries do, including that 59.62 sits below
TARGET (80) and is therefore a ratchet candidate like planning-inspect at 56 —
comfortably clear of its own floor with real room to grow. Raise it as the tests
improve; never lower it.

Worth stating plainly: 168 surviving mutants is not a clean bill of health. It is
an honest floor for a module that had NO mutation coverage at all an hour ago,
and it is now pinned so it cannot silently regress.

8da2dd3ad2 feat(#2790): add read-only planning.inspect schema-v1 snapshot query (#3708)
* feat(#2790): add read-only planning.inspect schema-v1 snapshot query

Adds a read-only query emitting a schema-versioned JSON projection of .planning/
so downstream harness UIs can consume planning state without parsing GSD's
Markdown a second time.

Composed strictly from the ADR-3180 section 7 owners plus parsePlanDocument,
parseRequirements and parseUatItems; markdown structure is read through the
Markdown Sectionizer and Markdown Table Model seams. It declares its own flat
external schema rather than serializing PlanningSnapshot, which is the
diagnostic-rule subject and still growing.

Extracts plan-document parsing out of cmdPhasePlanIndex into a shared leaf
module so phase.plan-index and planning.inspect cannot drift, including the
plan-id derivation both surfaces report.

Also fixes parseRequirements dropping the separator delimiter used by the
shipped requirements template, surfaced while wiring the requirement rows.

* fix(#2790): close spec gaps and a raw-text test assertion found in review

Review findings from the standards, spec and security passes:

- phases[] rows carry goal and dependencies, the two per-phase elements the
  issue Summary names that had no corresponding field. Goal is bounded to the
  section's leading prose so the Depends-on line, the Plans checklist and the
  wave annotations are not duplicated into it.
- requirement rows carry their own diagnostic codes, so a consumer no longer
  has to string-parse the global diagnostics subject to correlate.
- roadmap_acceptance.checkbox is looked up through the phase-id key owners.
  It was compared raw against the on-disk directory name, so it read null for
  every real-world slugged phase directory and the evidence channel was inert.
- the hostile-input test asserts the structured payload instead of matching the
  raw stdout string. The absence proof over raw stdout is kept deliberately.

* fix(#2790): register planning in the runtime usage list and repair fixtures

Remote runner reported 9 failures on 9b3f9aa. Two root causes, both fixed:

- gsd-tools.cjs registered the planning family in HOST_COMMAND_ROUTERS but
  never added it to TOP_LEVEL_USAGE's Commands list. Those are two surfaces a
  parity test guards, and the top-of-file block comment is not the runtime
  help string. A real wiring gap that every local gate and three review passes
  missed.

- the new suite's fixtures could not produce a resolvable phase set. STATE.md
  frontmatter omitted the milestone field, which ADR-3180 7.2 rule 1 makes the
  primary milestone selector, so the phase set scoped unscoped and every
  percentage was correctly withheld. Separately declarePhase returned a path
  without creating the directory, so a phase declared but never written to left
  phases empty. Both reproduced against the built module before fixing.

No assertion was weakened. The withholding path is still exercised and still
returns null when the roadmap is absent.

* chore(#2790): backfill changeset pr number

* test(#2790): cover every enumerated matrix row and contain a symlink escape

Reverses a silent deferral. An earlier revision left 23 of the 78 enumerated
matrix rows unimplemented and 7 more as one-off manual checks, with a paragraph
in the artifact and the PR body describing the gap. CLAUDE.md is explicit that
such a note is not a fix and is not surfacing. The rows are implemented instead
and the manual-evidence bucket is gone: 49 test cases become 88, covering all 78.

Writing the symlink row proved a real leak: a *-PLAN.md symlinked outside
.planning/ had its content emitted into the payload, confirmed via a direct call
and the spawned CLI. readDocument now resolves target and planning root with
realpathSync and rejects an escape, returning the ordinary unreadable-document
shape. Tested both ways, because a containment check that over-rejects is its own
defect: an escaping symlink leaks nothing and degrades that plan alone, while a
legitimately relocated .planning/ symlink stays fully readable.

The three new modules are registered in the mutation COVERED registry, which had
been reporting has_work false and skipping the Stryker gate entirely. Provisional
non-binding floors so the shards run and report; raised to the measured value
before merge, since the registry forbids calibrating from a local run.

* fix(#2790): satisfy the mutation ratchet contract and scope the 1MB test

Remote runner reported 16 failures on 8c451ed. Two causes.

The COVERED registry has a paired contract the earlier commit violated: every
module needs a matching RATCHET_BASELINE entry, and minScore must be between 50
and 100 with minScore === baseline. The provisional floor of 1 was illegal on
both counts. All three modules now sit at 50 — the registry's own enforced
minimum — with matching baselines. The score cannot be measured locally: the
shard runs node --test, which this repo hard-blocks, so CI is the only source.
Floors are raised to the measured value once this PR's shards report; a shard
below 50 means the tests need strengthening, since the floor cannot go lower.

The 1MB test was measuring the test harness rather than the product. The command
handles the oversized payload correctly by spilling to a tmpfile and resolving it
back, but the resolved stdout then exceeds runGsdTools' maxBuffer and the helper
reports ENOBUFS. It now uses --pick so stdout stays one byte while the full 1MB
document is still read and parsed end to end.

* fix(#2790): wire containment across every document read this command drives

An isolated security review of the containment control found the boundary logic
sound but not comprehensively wired: two content reads reached the filesystem
without it.

An escaped phase DIRECTORY could enumerate external filenames into the file
fields and diagnostic subjects. Both enumeration sites now containment-check the
directory before reading. Worth recording that the leak was already prevented one
layer earlier than the review claimed: Dirent#isDirectory() reports false for a
directory symlink, so such a directory never becomes a phase row at all. The
guard is defense-in-depth for a direct caller and for platforms where a reparse
point reports as a directory.

A *-VERIFICATION.md symlinked outside the root leaked one frontmatter value
verbatim, because readVerificationStatus does its own read and copies an
unrecognized status into the payload's next_action. Closed from the consumer
side through that function's existing fs injection seam, so src/verification.cts
keeps its signature and its other callers are untouched.

The reviewer additionally rated a forged status: passed as an integrity bypass.
It is not: anyone able to plant the symlink can plant a real VERIFICATION.md
saying the same thing. The incremental risk is confidentiality, which is what
these fixes close.

src/plan-scan.cts is deliberately unchanged: isPlanSuperseded reads
symlink-followed content but yields only a derived boolean, no document text.

* test(#2790): give the mutation shards an in-process surface

Two Stryker shards were CANCELLED at the 15-minute cap, not failed on score.
CI log: 640 mutants instrumented, and the dry run reported 'Ran 1 tests in 20
seconds' because the shards pointed at the integration suite, where nearly every
case spawns a gsd-tools subprocess and Stryker's command runner treats the whole
test-runner invocation as a single test. 640 x 20s cannot finish in 15 minutes;
at the kill it was 27/640 with an ETA over an hour.

Every other COVERED module points at a property or unit file, and the workflow's
own paths filter lists exactly those two patterns. In-process is the intended
mutation surface; the shards were pointed at the wrong shape of test.

Adds tests/planning-inspect.unit.test.cjs — 39 cases in 10 describes that spawn
nothing and call the built modules directly. plan-document and the router need no
filesystem at all, one being a pure content-to-object parser and the other taking
an injected mock. The three shards now point here. The 91-case integration suite
is untouched and still runs in the normal test job.

* chore(#2790): ratchet mutation floors to the measured CI scores

CI run 32392791843 measured all three shards, which is the only source the
registry accepts — local runs count timeouts as kills and inflate badly.

  planning-command-router  95.65 -> floor 94
  plan-document            76.58 -> floor 75
  planning-inspect         57.03 -> floor 56

Applied the registry's own rule, floor(score) - 1, and updated RATCHET_BASELINE
to match, since the ratchet test enforces equality.

planning-inspect sits well below the file's target of 80 and is the obvious
ratchet candidate as its tests improve. planning-command-router already exceeds
the target. The placeholder comment about floors pending measurement is removed
rather than left standing as a false statement.

79781e68eb enhance(#2401): ground verify-command paths and inherit prior-phase commands (#3678)
* feat(#2401): ground <automated> verify-command paths and inherit prior-phase commands

Adds a deterministic resolvability probe over each PLAN.md <automated> verify
command and surfaces the nearest prior phase's proven commands to the planner
at every context window.

- src/verify-command-grounding.cts: recognizer (not a shell interpreter) that
  grounds a leading cd <literal> chain and npm --prefix <literal>, and reports
  unresolvable rather than guessing. Never executes command text.
- gsd-tools check verify-command-paths <N>: per-phase probe, wired into
  plan-phase.md before the plan-check pass.
- init.plan-phase gains prior_verify_commands, ungated by context_window.
- gsd-plan-checker: new Verify Command Path Resolvability dimension that
  reports the failing target and never prescribes a replacement.

Also fixes first-match-wins prefix bucketing in scripts/lint-test-file-count.cjs
(readdir order is not stable across platforms, so a module whose name extends
another's with a hyphen bucketed differently on Linux than on macOS).

Closes #2401

* fix(#2401): ground the canonical --prefix form, quoted paths, and absolute cd resets

Independent review found three defects in the recognizer:

- npm --prefix DIR run SCRIPT never reached the script-existence check,
  because the pattern required npm and run to be adjacent. That is the
  form the docs tell planners to prefer, so script_missing never fired
  for it. The prefix flag and its value are now stripped before matching.
- --prefix captured with \S+, so a quoted path containing a space was
  truncated to a stray opening quote and reported as a missing directory
  - a false blocker, worse than the bug this feature fixes. The capture
  is now quote-aware.
- A chained cd whose later segment was absolute concatenated instead of
  resetting, producing a nonsense path and another false blocker. The
  fold now resets on an absolute segment.

Also replaces the bespoke phase-directory regex with the canonical
phase-id helpers. Real phase directories are NN-slug, not phase-N-slug,
so the prior-command harvest matched nothing outside its own fixtures
and the planner-inheritance half of this feature was dead code.

* refactor(#2401): source task blocks from the canonical sectionizer

The module carried its own copy of the <task>-block grammar - a fourth
hand-rolled mirror of the one markdown-sectionizer owns. verify.cts keeps
its copy only because it needs the type= attribute the canonical helper
discards; this module never reads that attribute, so it can share the
owner outright instead of adding a test around a copy.

extractAutomatedCommands now takes task bodies from extractTaggedBlocks
and the out-of-task remainder from stripTaggedBlocks. A task-grammar
parity test pins the attributed task-name set against the canonical
helper across six awkward task shapes.

* fix(#2401): extract agent-file overflow to references and repair the property arbitrary

The remote matrix run came back red with 19 failures, four root causes:

- agents/gsd-plan-checker.md and agents/gsd-planner.md both blew the
  49152 agent cap. Their bodies move to gsd-core/references/, leaving
  @-reference stubs, per the documented overflow pattern.
- The new checker dimension invoked gsd_run before the canonical
  preamble that defines it. The call is deleted outright: plan-phase.md
  already runs the probe and hands the result in as {VERIFY_PATHS}, so
  the dimension consumes that rather than re-running anything.
- fc.fullUnicodeString does not exist in fast-check 4.8.0. Replaced with
  fc.string({ unit: 'binary' }), which covers the same 0000-10FFFF range.
- Three runtime-loaded files grew; acknowledged in the existing ack
  fragments that already own those bare filenames, since two ack sources
  may never name the same path.

* chore(#2401): backfill changeset pr number to 3678

* fix(#2401): treat ~ as a home expansion only at the start of a path

Windows CI caught this on both shards; the Linux-only remote matrix
cannot see it. The dynamic-path refusal rejected ~ anywhere, and a
GitHub Windows runner's tmpdir is an 8.3 short name -
C:\Users\RUNNER~1\AppData\Local\Temp - so a valid absolute Windows
path came back unresolvable/dynamic_path.

This was a production bug, not a test artifact: any Windows user whose
project path carries an 8.3 short name, or any literal ~, silently lost
the probe entirely - every command degrading to unresolvable with no
explanation.

~ is a home expansion only at the start of a path; elsewhere it is an
ordinary literal. The check is now split: $, backtick, *, ? and newline
stay refused anywhere (substitution and globs, and the glob characters
are illegal in Windows path components regardless), while ~ is refused
only leading, tolerating one leading quote since the check runs before
quote stripping.

The prior tests only caught this on Windows because only Windows puts a
~ in tmpdir. Four new tests pin it on every platform via a fixture
directory literally named RUNNER~1.

1adf6d2245 fix(#3620): point the docs at files that actually exist (#3658)
* fix(3620): point the docs at files that actually exist

docproof found 34 stale references; the reporter hand-read all 34 and reported the 8 that
are real, explaining why the other 26 are deliberate (files the documents themselves label
legacy or "superseded by", and one pre-Diataxis link label whose target still resolves).
Those 26 are left alone — re-touching them would contradict the issue's own analysis.

Every claim was re-verified against git ls-files at HEAD before editing.

docs/INVENTORY.md said its roster is anchored by six drift-control tests. Five are gone
(commands-doc-parity, agents-doc-parity, cli-modules-doc-parity, hooks-doc-parity in
5d8a8c4d; command-count-sync in fbf30792), so the sentence now names the one that exists.
Whether one test is sufficient coverage is a maintainer question the issue explicitly
declined to answer, so no new drift tests are proposed here.

The four translations were a revision further behind, each naming a seventh test deleted in
ae8bb707 that the English file had already dropped. All four now match.

Renamed targets corrected in CONTEXT.md, VERSIONING.md, docs/CONFIGURATION.md and the
update workflow. The new test names carry no issue-NNN- prefix, which is what
lint-regression-test-names requires, so they are the correct targets.

docs/TESTING-SUITES.md is the one that could cost somebody time: it INSTRUCTED contributors
to add an acknowledgment to the legacy drift-ack file, which CONTRIBUTING.md says to never
use. Rewritten from the real workflow — per-PR fragments under the drift-acks directory,
and a spent base-side ack is re-armed by rewording that fragment's reason in place, never
by adding a duplicate, since two sources naming one path is a hard error.

docs/skills/discovery-contract.md's heading named a query module deleted in 11918dcc. The
section was REMOVED rather than retargeted: its documented behavior (skip the deprecated
root) is not what the surviving code does — skill-manifest includes that root marked
deprecated:true — so retargeting would have documented something false.

Found and fixed inline, same class: VERSIONING.md described an SDK bundling step the
release workflow does not have (zero such mentions in that file); CONFIGURATION.md and four
translations named a dead model-catalog triple collapsed by ADR-457.

Dead config removed: the changeset lint's user-facing prefix list still carried two retired
sdk entries. git ls-files -- 'sdk/*' returns nothing. No test pins that array.

Left deliberately: the comment explaining the retired catalog path, the install regression
test that reconstructs the old broken layout to prove it fails, and the generated
test-timings cache. Each is a legitimate mention of a dead path, not drift.

Note lint-removed-but-needed cannot catch this class: it diffs baseRef...HEAD, so it only
sees files deleted in the change under review. These were orphaned by PRs that predate the
lint. A repo-wide existence audit would need a suppression mechanism for the 26 deliberate
mentions above; that is a feature, not part of this fix.

bf2332e67c fix(#3582): route every hook's compiled-module require through the self-heal build seam (#3629)
* test(3582): failing-first cold-tree coverage and the seam drift lint

On a plugin-channel install the compiled gsd-core/bin/lib/*.cjs are legitimately
absent (ADR-457 build-at-publish; the npm package builds before publishing, a raw
tree materialization never does). gsd-tools.cjs calls ensureRuntimeBuild() before
requiring ./lib; no hook does, so the isolation guard's Cannot-find-module lands in
its fail-closed catch and is misreported as an unreadable dispatch-isolation
configuration, blocking every executor dispatch.

These tests fail on that: cold-tree runs of the isolation guard, statusline, cursor
guard and update worker, plus the seam's actionable build error surfacing instead of
the generic misreport.

Also adds the drift lint the acceptance criteria require, with a fixture proving it
CAN fail — a guard never shown to fail is worthless. It is red here by design: it
flags today's unfixed hooks, which is exactly the defect.

* fix(3582): route every hook's compiled-module require through the self-heal seam

RED proven at 5b174b0d: 11 failures — the cold-tree runs for the isolation guard,
cursor guard and update worker, the fail-closed-with-actionable-message assertion, and
the lint's own real-tree check.

The compiled runtime library is produced by build:lib and gitignored (ADR-457,
build-at-publish). The npm package builds before publishing; a plugin-marketplace or
git-clone install materializes the raw tree and never does, so on that channel those
modules are legitimately absent. The self-heal seam added by #2002 exists to heal exactly
this, and the CLI entrypoint already calls it — no hook did. The isolation guard's
Cannot-find-module therefore landed in its fail-closed catch and was reported as
'could not read or resolve dispatch-isolation configuration', so an ARTIFACT ABSENCE was
misdiagnosed as an unreadable project config and every executor dispatch was blocked.

All SEVEN affected files now call the seam before their first compiled require. The issue
named four; a scan found six; implementing it surfaced a seventh — the shared isolation
sentinel helper, used by BOTH guards, which requires two compiled modules itself and
would have defeated the guards' own fix on a genuinely cold tree. Same defect class, so
fixed here rather than left as a known-broken remainder.

Failure posture is deliberately split by hook kind:
- Gates (agent isolation guard, cursor subagent start) surface the seam's actionable
  build error distinctly instead of swallowing it into the generic text, and stay
  fail-closed — a genuinely unreadable project config still DENIES exactly as before.
- Cosmetic and detached hooks (statusline, update worker, update check, update banner)
  DEGRADE rather than crash: the statusline draws on every render and the worker is a
  detached process, so a build failure there must not take down the prompt.

The npm path is untouched: the seam's already-built fast path returns immediately, so
prebuilt installs pay nothing and behave bit-for-bit as before.

Adds a drift lint, wired into the CI lint chain, so the invariant is enforced rather than
remembered — without it the next hook to add a compiled require reintroduces the class
silently. It is proven able to fail: a fixture hook requiring a compiled module without
the seam is flagged, and one that uses the seam is not. Verified directly — on the
unfixed tree it named all seven offenders; with the fix it passes.

While writing the lint's comment stripper, a naive whole-text block-comment regex ate its
own fixture, because this repo's comments legitimately spell the compiled-lib glob whose
star-slash reads as a comment opener. Rewritten as a line-based scanner with a regression
test pinning that case.

* fix(3582): test the three untested seam call sites and assert typed reason codes

Two independent reviews converged on the same major gap: the fix wired the seam into
seven files but only four had cold-tree tests. The adversarial pass put it plainly —
deleting the shared isolation-sentinel helper's seam call would not have failed any test
in the diff. That file was my own addition beyond the issue's four, so it shipped
untested; that is now closed.

- Shared isolation-sentinel helper: its seam call is only reached when .planning is NOT
  directly under cwd, and every existing cold-tree fixture puts it there, so the early
  return always fired first. Now covered, and proven load-bearing by mutation: with the
  call removed the spy records zero seam invocations and the test fails.
- update-check hook and update-banner hook: cold-tree tests added asserting the DEGRADED
  VERDICT — the fallback cache filename, and silent suppression when the package name
  degrades to null — rather than merely 'did not throw'. The banner hook previously had
  no test file at all.

Standards violation fixed: two tests asserted on free-form prose via assert.match against
a JSON reason string, which CONTRIBUTING bans by name — its own BAD example is exactly
that. The ESLint rule only covers readFileSync/spawnSync text, so tooling did not catch
it. Both isolation guards now emit a machine-readable reason_code from a frozen enum,
following the repo's existing REASON convention, and the tests assert that instead. The
human-readable message is unchanged for operators; only the assertion target moved.

The duplicated degrade boilerplate across the three cosmetic hooks was deliberately NOT
extracted, and the reason is recorded at each site: both viable shapes — a
path-parameterized helper, or a ceremony-only wrapper — defeat the drift lint's per-file
literal co-occurrence check, so extracting would require the lint to special-case its own
helper. Triplication is the lesser evil while the lint stays a co-occurrence scan.

The lint's header now states what it does and does not catch (literal quoted requires
only; hooks/ scan root), so a future reader does not over-trust a guard that a
concatenated path or a require inside a non-hooks helper would evade.

* chore(3582): regenerate the committed install-tree fixtures

Adding a new shipped hook helper changed the install tree, and those fixtures are
committed-and-derived (regen:derived / gen:install-tree), so 12 'install tree — <runtime>'
tests failed on 541a1913. Regenerated rather than hand-edited.

The delta across all 15 runtime fixtures is exactly two lines — the new helper under both
its hooks/ and gsd-hooks/ install paths — and nothing else, so the regeneration pulled in
no unrelated drift.

This is the bookkeeping ripple a new file under hooks/ carries; it was not visible from
lint:ci, which passed both before and after.

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

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

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

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

Closes #3597

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

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

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

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

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

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

Closes #3597

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

c5b83cb050 chore(#3560): delete two unreachable workflows, gate workflow reachability in lint (#3564)
* chore(#3560): delete two unreachable workflows, gate reachability in lint

discovery-phase.md and plan-milestone-gaps.md shipped to all 19 runtime
install trees with no command, agent, or skill referencing them.
plan-milestone-gaps' command was deleted by #2790 and the workflow was
left behind; discovery-phase's own header claimed a caller in
plan-phase.md's mandatory_discovery step, and that step does not exist —
plan-phase.md contains zero occurrences of "discovery".

docs/INVENTORY.md asserted discovery-phase.md was an alternate entry for
/gsd-new-project. new-project.md never referenced it. The row and the
matching note sentence are removed across all five locales rather than
corrected.

Adds rule 6 to lint-command-contract: every shipped workflow must be
reachable from a loader, walking the transitive closure over the three
reference shapes this repo uses. The closure seeds ONLY from
commands/agents/skills, so a workflow that references only itself and a
pair that reference only each other are both correctly reported rather
than satisfying themselves; a visited set makes reference cycles
terminate. The measure is a mention in a LOADER — docs/ and install-tree
fixtures deliberately do not count, because scan.md proved a file can be
documented and shipped while entirely unreached.

Ships blocking, not report-only: #3561 is in this branch's base, so the
tree reports 0 unreachable from the start.

Closes #3560

* test(#3560): drive rule 6 end-to-end, sweep a stale allowlist, update ADR-0002

Review findings.

Rule 6 had no end-to-end coverage: the tests exercised the pure closure
with in-memory data, so the wiring — file collection, exit code,
diagnostic — was unproven, and #3560's acceptance list explicitly wants
a fixture showing the rule FAILS on a planted orphan. Adds an optional
--root to lint-command-contract (default behavior unchanged) and four
tests driving the real CLI through the process seam against a temp
fixture: clean=0, planted orphan=1, orphan referenced only from docs/=1,
orphan reachable transitively=0. The docs/ case is what pins the
Goodhart defense — a mention outside a loader must not confer
reachability.

Deletes two tests that were byte-identical to a third and could not
assert anything loader-specific, since the closure is source-agnostic by
design; that distinction lives in the lint script's file collection and
is now covered above.

Removes a stale ALLOWLIST entry for discovery-phase.md in
planner-language-regression — the exact sweep-miss class rule 6 exists
to catch, found in the PR that adds the rule.

ADR-0002 described five per-file frontmatter checks; rule 6 is a
repo-level reachability graph, so the Decision section now says so.

Refs #3560

* test(#3560): cut the bug-3298 test pin on the deleted plan-milestone-gaps workflow

The remote runner went red with four failures: tests/phase.test.cjs
asserted the plan-milestone-gaps workflow exists and checked its mkdir
patterns, so deleting the file broke the test that pinned it. This is the
fence the epic describes — the content-sync test IS what keeps an
unreachable file alive — and cutting the coupling is what makes the
deletion safe.

Removes only that arm. The bug-3298 block guards three workflows against
phase-dir prefix drift; the import and add-backlog arms and both shared
mkdir-pattern helpers are untouched.

Worth recording where the sweep failed: my reachability walk covered
commands, agents, skills, gsd-core and docs, and lint-removed-but-needed
covers .github/workflows, gsd-core, docs and package.json. Neither looks
at tests/, so a test-pinned deletion is invisible to both and surfaces
only on the remote runner. The how-to added by this PR names that gap
explicitly so the next deletion searches tests/ by hand.

e6e32da224 fix(#3561): route /gsd-map-codebase --fast to a scan.md path the runtime can resolve (#3562)
* test(#3561): failing-first coverage for the --fast dangling dispatch

/gsd-map-codebase --fast routes to "the scan workflow" in prose, but
commands/gsd/map-codebase.md names no resolvable path and its
execution_context includes only map-codebase.md, so scan.md is never
loaded. Same class as epic #1891's F8/F9: dispatch keyed on a token
that never arrives.

Adds workflowPathRefs() to command-contract-helpers.cjs — one shared
pure resolver for the three reference shapes this repo uses (eager
@-include, lazy absolute-ish path, lazy parent-relative steps//modes/
path). Placing it in the helpers module keeps the lint script and the
test suite reading the same definition, which is what that module
exists for; #3560 consumes the same function rather than re-deriving it.

Tests 16/17 are RED until the routing fix lands.

Refs #3561

* fix(#3561): route --fast to a scan.md path the runtime can resolve

commands/gsd/map-codebase.md documented --fast and told the agent to
"run the scan workflow", but named no path and included only
map-codebase.md in execution_context, so gsd-core/workflows/scan.md was
never loaded and the single-agent scan was improvised.

Names the path in the routing line so it is read on demand, rather than
adding an eager @-include: --fast is the minority path and the
progressive-disclosure split (#717) exists to keep the common full-map
invocation from paying for it. The accompanying test pins that choice —
execution_context must still carry exactly one @-ref.

skills/gsd-map-codebase/SKILL.md is regenerated, not hand-edited.

Closes #3561

* fix(#3561): bound the .md match and bind the regression test to the --fast line

Two majors from the isolated adversarial review.

Both resolver regexes ended at a literal .md with no trailing boundary,
so a longer extension was truncated into a plausible-looking but wrong
path: workflows/foobar.mdx returned workflows/foobar.md. Adds a
(?![A-Za-z0-9_]) lookahead to both shapes so .mdx and .md5 are rejected
outright rather than silently rewritten.

The regression test scanned the whole command file, so it did not bind
to the defect — the reviewer showed that an unrelated comment mentioning
scan.md anywhere made it pass while the dispatch defect was still
present. It now extracts the "- If it is `--fast`" bullet and scans that
line alone, and a new test drives a synthetic pre-fix fixture to prove
the false-pass path is closed.

1591454357 feat(#3409): reject shell guards that cannot observe their own failure arm (#3558)
* test(#3409): failing-first regression tests for unreachable shell guard arms

Drives the three live defects fail-first, executing the shipped workflow
snippets rather than a re-typed copy:

- G1/G2 plan-phase.md Walking Skeleton gate reads `--pick summaries_total`,
  a field that does not exist, so PRIOR_SUMMARIES is always "" and the gate
  has never fired (#3365). G2 is the load-bearing negative-space case: it
  rejects a fix that treats "no answer" as "zero" and fires unconditionally.
- G3 plan-phase.md PHASE_REQ_IDS resolves "" instead of the TBD sentinel on
  a phase with zero requirements.
- G4 complete-milestone.md's bare `cat <glob>` blocks on stdin under a
  nullglob left set by an earlier block (measured hang).

Skipped on Windows for G4 only: the FIFO-blocked-stdin mechanism is POSIX
only, and a weakened assertion there would pass vacuously.

Refs #3409

* fix(#3409): make nine shell guards observe their own failure arm

`--pick` coerces a missing field to empty string and exits 0, so the
`|| echo <default>` fallback after it fires only on a verb typo, never on
the field absence it was written for. Nine sites relied on that arm.

- plan-phase.md walking-skeleton gate: `--pick summaries_total` names a
  field that does not exist under any flag combination, so the gate has
  never fired on any project (#3365). Repointed at the existing single
  owner, `phases.list --type summaries --pick count`, which returns a real
  integer in every case including a project with no `.planning` directory.
  No new counter is added: a second one would duplicate the ownership
  ADR-3180 Decision 1 forbids. The gate now fires only on a literal "0",
  so an unanswerable query fails safe instead of entering skeleton mode.
- plan-phase.md phase_req_ids: now falls back to the documented TBD.
- The remaining seven convert to an explicit empty test.
- complete-milestone.md read all phase summaries through a bare
  `cat <glob>`; under a nullglob left set by an earlier block that is zero
  operands, so cat blocks on stdin. Guarded with the array shape the
  #3300 fix already established in review.md.

Refs #3409

* fix(#3409): guard eleven more globs that defeat their own fallback arm

The nullglob audit this issue asks for turned up the same class in files
#3300 never touched.

- Eight bare `cat <glob>` reads (transition, complete-milestone, planner x4,
  verifier, phase-researcher). With nullglob set that is zero operands, so
  cat reads stdin and blocks; measured rc=137 at 3s.
- Three `ls <glob> || echo "<message>"` sites (session-report,
  review-backlog and its generated skill). nullglob makes ls succeed
  listing the cwd, so the message never prints and the user gets a
  directory listing instead.

Guarded with `[ -e "${_ARR[0]}" ]` rather than `[ ${#_ARR[@]} -gt 0 ]`.
The count form is correct only when nullglob is set, and six of these
seven files never set it: without it the array holds the unmatched literal
pattern, so the count is 1 and the guard passes wrongly. `-e` is correct
in both worlds. review.md keeps its count guards — that block sets
nullglob two lines above them.

skills/gsd-review-backlog regenerated from commands/, never hand-edited.

Refs #3409

* feat(#3409): add the unreachable-shell-guard drift lint

A sibling of lint-planning-prompt-drift.cjs, consuming the shared
scripts/lib/drift-scan.cjs rather than copying it, wired into lint:ci.

Both detectors are one shape — a fallback arm defeated by a legitimate
success-on-empty:

- Detector A: `--pick` and `|| echo` on one line. `--pick` is the
  discriminator because "missing field renders empty at exit 0" is a
  documented CLI contract, not a heuristic. A rule keyed on gsd_run
  matched 111 lines, ~132 of them legitimate, and was rejected.
- Detector B: `cat <glob>` in command position, and `ls <glob>` whose
  exit code feeds a real fallback or an if/while head. Informational
  `ls <glob>` whose stdout is consumed (97 sites) and `|| true` failure
  suppression (~15) are not guards and never fire.

Shrink-only ratchet keyed on (file, trimmed text) with a per-pair count,
POSIX-normalized unconditionally so Windows CI cannot report everything
fresh and stale at once. Ships with a ZERO-entry baseline: every site it
can find is fixed. Exemption is the per-line `# gsd-scan-ignore: #NNN`
marker whose reason must name an issue or URL; a malformed reason reports
a distinct error rather than silently exempting. No file allowlists.

ADR-3409 records the invariant, the measurements behind both detectors,
and why the upstream `--pick` contract fix belongs to #3473.

* fix(#3409): resolve review findings — typed surface, sanitized reports, tighter marker

Standards axis (blocker): the guard's tests asserted on human-readable
stdout/stderr and on free-form baseline-load prose, which CONTRIBUTING
prohibits by name. Added the typed surface it prescribes instead of
weakening the tests: a frozen REASON enum, a --json report mode,
structured loadBaseline errors, and a test locking Object.keys(REASON)
so a new reason stays three coordinated changes.

Security axis: sanitizeForReport covered every violation field but not
the baseline-load error path, which embeds raw JSON.stringify output --
that escapes nothing above 0x1f, so bidi and C1 controls reached CI logs
unfiltered. Routed through the sanitizer at the output seam.

Security axis: the scan-ignore marker accepted `#0` and a bare
`http://`. Tightened to a positive issue number and a URL with a host.
This diverges deliberately from the sibling in
tests/commit-files-pathspec.test.cjs, whose looser form was copied
verbatim; the header now records the divergence.

Security axis: G4 built its FIFO with `mktemp -u`, reserving a name
without creating it. Now created inside a `mktemp -d` directory.

Spec axis: ADR-3409 claimed a ninth site landed after the issue was
filed. git blame disproves it -- all nine predate it; the issue's hand
count missed one. Corrected. The design and test matrix still specified
B9 as a FLAG after implementation reversed it to PASS; both now record
the reversal and why.

Refs #3409

* docs(#3409): add the how-to for resolving unreachable-guard findings

Reference and Explanation are carried by ADR-3409; this is the
task-oriented quadrant CI cannot check for.

The page exists mainly for one thing the lint structurally cannot catch:
both `[ -e "${_ARR[0]}" ]` and `[ ${#_ARR[@]} -gt 0 ]` remove the glob
from the command and therefore both pass, but the count form is correct
only when nullglob is set — and nullglob is usually set in a different
block of the same file. A reference table cannot carry that; a how-to can.

Also documents the reason codes, so a reader can tell "nothing to report"
from "could not look".

No tutorial: this is a gate inside an existing CI loop, not a new entry
point a newcomer starts from.

* fix(#3409): bring the touched prompt files back under their size gates

The remote run was red on 14 tests, all size/attribution, none of them
the regression suite.

- agents/gsd-planner.md was 194 chars over a 49152 cap enforced by four
  separate tests, each of which says the remedy is extraction, not a bump.
  It had 41 chars of headroom before this branch. Its `## Checkpoint
  Types` section was an unlinked, condensed duplicate of
  references/checkpoints.md, which already carries all three types and
  their XML shapes; the section now points there and keeps the three
  names and percentages inline. Net -969, margin 1010.
- gsd-core/workflows/execute-phase.md sat 2 chars under a comfortable
  margin assertion. Dropped the AUTO_MODE default: the `|| echo "false"`
  it replaced was unreachable, so the value was already sometimes empty
  on next, and its only consumer compares against `true`. Net -16.
  Left plan-phase.md's AUTO_CHAIN default alone -- that file names an
  explicit `false` branch, so empty would match neither branch.
- Acknowledged the seven prompt files that genuinely grew, one specific
  reason each. Five of those paths were already claimed by spent
  fragments identical to next, which blocks a second source naming the
  same path; removed just the colliding key from each, deleting the two
  that this emptied.

Refs #3409

* test(#3409): extract the whole PHASE_REQ_IDS block, not just its first line

G3 failed on the remote runner with '' !== 'TBD'. The test was wrong, not
the workflow.

The shipped contract is now two consecutive lines -- the capture and the
`${PHASE_REQ_IDS:-TBD}` default -- but the helper's `^PREFIX=.*$` regex
returns only the first match, so the test executed half the contract and
correctly observed the empty string. Renamed to extractAssignmentBlockFor
and taught it to consume the contiguous run of lines sharing the prefix.

The assertion is untouched: TBD is the right expectation, and weakening
it to accept the empty string would have reinstated exactly the class
this suite exists to catch -- a check that cannot observe the thing it
is checking.

extractFencedBashAfterAnchor is unaffected: it is fence-delimited rather
than line-anchored, so G1/G2/G4 still capture their full blocks.

Refs #3409

* chore(#3409): drop a spent ack fragment that collided on complete-milestone.md

#3458 landed on next while this branch was in flight and its fragment
claims complete-milestone.md, which this branch also grows. Two ack
sources may never name the same path.

Its entry is spent: the +9163 it explains is already absorbed at base, so
it can no longer clear anything, and the checker's own guidance for spent
entries is to delete them. Removing the key emptied the fragment, so the
file goes too -- an empty one signals nothing.

Refs #3409

* chore(#3409): backfill changeset pr number 3558

* test(#3409): hoist a regex subject out of exec() to clear the injection scan

CI's prompt-injection scan flagged `MARKER_RE.exec('# gsd-scan-ignore: ...')`.
The pattern `exec[[:space:]]*\(["']` is receiver-blind on purpose, so it
catches `require('child_process').exec('...')` -- and the scanner's own
header records that RegExp.prototype.exec is collateral, to be handled by
its allowlist.

Allowlisting the file would blind it to the real exec vector permanently,
so the subject is hoisted into a const instead: same assertion, scanner
left at full strength, no security surface widened.

abf3cf7c25 fix(#3458): scan archived milestone phases, and make [A] Acknowledge actually suppress (#3555)
* fix(#3458): scan archived milestone phases in the four audit-open scanners

`query audit-open` resolved exactly one phase root, `.planning/phases/`. When a
milestone closes its phase directories move to
`.planning/milestones/v<X.Y>-phases/`, so an item still unresolved at that
moment — the `[R]/[A]/[C]` prompt accepts "accept" and "carry forward", not only
"resolve" — became invisible to the v1.1 pre-close audit and every audit after
it. The window in which an unresolved item is visible to this gate was exactly
one milestone wide, and nothing announced when it closed.

Reproduced before fixing, with byte-identical artifacts in the two layouts and
the active layout as the control:

  active   → has_open_items=true   deferred=1  uat_gaps=1  total=2
  archived → has_open_items=false  deferred=0  uat_gaps=0  total=0

`scanDeferredItems`' own doc comment names this as the thing it was built to
prevent — "phase directories archive to `milestones/vX.Y-phases/` (#1871) and
the entry leaves the live tree having never been triaged" — while the
implementation eleven lines below cannot read that path. It catches an entry at
its own milestone close and goes blind at precisely the transition the comment
describes.

This is not cosmetic under-reporting. `auditOpenArtifacts` sums all nine
category counts into `counts.total` and returns `has_open_items: counts.total >
0`, so four blind scanners can flip the gate's headline boolean and let
`/gsd-complete-milestone` assert a clean close it never verified. In a
fully-archived project `.planning/phases/` may not exist at all, and the
scanners' `if (!fs.existsSync(phasesDir)) return []` produced a value
indistinguishable from "nothing is open".

## One enumeration, not four

The four scanners each hand-rolled the same active-only walk. They now share
`listAuditPhaseTargets(planDir, cwd)`, which yields both roots — the shape of
fix epic #3473's B2 asks for, and the reason the fix is one seam rather than
four edits.

Three properties are load-bearing:

  * the ACTIVE enumeration is unchanged — still a raw `readdirSync`, NOT
    `listMilestonePhaseDirs`. These scanners are deliberately not
    milestone-filtered today, and switching would silently add window and
    sentinel filtering: a behavior change belonging to #3372, not here.
  * a missing or unreadable active root skips that half instead of returning
    early. That early return WAS the bug in a fully-archived project.
  * archived dirs are deliberately NOT milestone-filtered, per the comment
    `src/uat.cts` already carries: archived phases belong to past milestones by
    definition, so applying the current-milestone filter discards every one and
    silently reinstates this bug.

Each item now carries `archived_milestone` when it comes from a closed
milestone, matching how the sibling module already labels archived results —
without it an operator triaging `[R]/[A]/[C]` cannot tell a live item from one
carried over. Additive: no existing test or doc asserted an exact key set.

`scripts/lint-phase-enumeration-drift.cjs`'s exemption list for this file drops
from the four scanner names to the single helper, since that is now the only
place the enumeration lives.

## Tests

Written failing-first and confirmed red for the right reason before the fix, all
four driven through the real `audit-open` CLI rather than private functions:
archived-only (was 0/0/0/0 with `has_open_items=false`, now 1/1/1/1 true),
mixed active+archived (was 1/1/1/1 — the archived half dropped — now 2/2/2/2),
active-only unchanged, and an all-resolved archived phase contributing 0.

That last one passed vacuously before the fix, because the archived path was not
reached at all; it was re-verified as genuinely discriminating afterward by
flipping one archived item to unresolved and watching the count rise.

* fix(#3458): restore the scan_error sentinel and show archive provenance

Adversarial review found one BLOCKER that the previous revision introduced,
which a green remote-runner suite did not catch because nothing in the tree
asserts `scan_error` at all.

## The regression

Consolidating four hand-rolled walks into `listAuditPhaseTargets` swallowed the
active-root `readdirSync` throw in a bare `catch {}`. Pre-fix each scanner
returned `[{scan_error: true, …}]`; after, each returned `[]`. Measured with
`.planning/phases` created as a FILE (so `existsSync` passes and `readdirSync`
throws ENOTDIR):

  before this fix: uat_gaps/verification_gaps/context_questions/deferred_items
                   each `[{"scan_error":true,…}]`
  the regression:  each `[]`

`complete-milestone.md` re-runs `audit-open --json` and reads those counts, so a
machine consumer could no longer tell "I/O failed" from "verified clean" — the
exact conflation this issue exists to remove, reintroduced on the failure path.
`listAuditPhaseTargets` now reports `activeUnreadable` and each scanner pushes
the sentinel shape recovered verbatim from `origin/next`, not reinvented.

The docstring claiming the active enumeration was "UNCHANGED" was false while
that sentinel was missing, and is corrected to state what is actually preserved.

An unreadable ARCHIVED root deliberately gets NO sentinel: there was no archived
read before, so there is no consumer contract to preserve, and adding one would
conflate the ordinary "no milestones archived yet" state with a real I/O failure.

## The operator could not see the archive

`formatAuditReport` is the surface the gate actually shows a human —
`complete-milestone.md` runs it without `--json` — and it never rendered
`archived_milestone`. With `01-alpha` in both roots the identical line printed
twice with nothing to tell them apart, and `[R] Resolve` sends the operator to
`.planning/phases/01-alpha/` where the archived one does not exist. Phase
numbering restarts at `01` after each archive, so that collision is the common
case, not an edge case. All four loops now render ` (archived vX.Y)`; active
lines stay byte-identical.

## Archived milestones sorted wrong

`getArchivedPhaseDirs` ordered milestones with `.sort().reverse()` —
lexicographic, so `v1.9` outranked `v1.10`. Measured order for v1.0/v1.9/v1.10
was `v1.9, v1.10, v1.0`. Now a numeric-segment descending compare. Pre-existing,
but this change is what first surfaces it in audit output.

## Tests

The blocker's regression test fails against the previous revision. Added:
`archived_milestone` present on archived items and absent (not `undefined`) on
active ones; the unreadable-active-root sentinel across all four categories; an
unreadable archived root still leaving the active half scanned; the
duplicate-name case producing two distinct entries that the human report
distinguishes; and the v1.10-before-v1.9 ordering.

`docs/COMMANDS.md` documents the archived scanning and the new field.

* fix(#3458): stop filesystem names forging lines in the audit report

Found by the security review of this branch. Pre-existing on `next`, fixed here
because it defeats the exact gate this PR is hardening.

`audit-open`'s human report is the surface `/gsd-complete-milestone` shows an
operator to decide whether a milestone may close. A `.planning/` tree authored
by someone other than that operator — a cloned repo — could contain a directory
literally named:

    zz<newline>0 open items require decisions.<newline><ESC>[2K<ESC>[1G FORGED

and the report printed `0 open items require decisions.` as its own line, with
raw ESC bytes reaching stdout able to erase or overwrite the lines above it.
Reproduced against the real CLI before fixing, and again after.

## Why not just harden sanitizeForDisplay

Because that helper's contract is multi-line prose — it removes protocol-leak
lines while deliberately preserving the newlines between legitimate ones, which
`tests/security.test.cjs` pins. Stripping CR/LF there would have broken a
correct test to paper over a different problem.

The two jobs are genuinely different, so there are now two helpers. New
`sanitizeLabel` (`src/security.cts`) is for values that are semantically ONE
LINE and derived from a filesystem NAME. It ESCAPES rather than strips C0
(including ESC/CR/LF), DEL and C1, so a doctored name renders visibly as
`\n` / `\x1b` instead of being silently normalized — the report stays honest
about what is in the tree. Ordinary input passes through byte-identical.

## Nine sites, not four

The first pass covered the four phase-scoped scanners. A sweep of the rest of
the file found the identical class in five more — `scanDebugSessions`,
`scanQuickTasks`, `scanThreads`, `scanTodos`, `scanSeeds` — emitting
name-derived `slug` / `filename` / `seed_id` through the prose sanitizer.
`scanQuickTasks`' `date` had no sanitization call at all.

Every emitted field in the file is now classified and the sweep recorded:
`slug`, `filename`, `seed_id`, `phase`, `file`, `archived_milestone`, `date` are
name-derived and take `sanitizeLabel`; `hypothesis`, `status`, `updated`,
`title`, `priority`, `area`, `summary`, `questions[]` and deferred-item `text`
are content and keep `sanitizeForDisplay`. No name-derived value reaches output
unsanitized.

`--json` was already safe — JSON string encoding escapes control characters, and
a crafted name cannot break out of the string. Verified rather than assumed.

* chore(#3458): backfill changeset pr number

* test(#3458): skip control-character fixtures where the OS forbids the name

CI red on `test (windows-latest, 24, shard 1/3)`: the four forgery-rejection
tests build directories whose names embed a newline and ESC, and NTFS forbids
control characters in path components, so `mkdir` threw ENOENT.

The remote runner is Linux-only, so it could not have caught this class.

Semantically the skip is honest rather than a workaround: on Windows the
directory-name forgery vector does not exist, because the OS refuses to create
the name. The sanitizer's own behavior stays covered there by the
`sanitizeLabel` unit tests, which are pure string tests with no filesystem
calls — verified.

Uses the repo's established capability-probe convention
(`tests/adr-index-gate.test.cjs`'s `trySymlink`), which `t.skip()`s on the real
errno rather than branching on `process.platform`, and whose comment gives the
reason: a bare `return` "would silently report a PASS ... and hide the gap this
guard exists to close". A skipped test is visibly skipped.

Swept every test added on this branch for names Windows would reject or POSIX
path assumptions; these four were the only ones.

* feat(#3458): make [A] Acknowledge actually suppress, without overwriting a verdict

Making archived phases visible exposed the other half of the problem: an item
unresolved at a milestone close now resurfaces at every later close forever,
because `[A] Acknowledge` wrote a prose block to STATE.md that
`auditOpenArtifacts` never reads. `verified_closeout` became unreachable and the
gate degraded to a mandatory `[A]` every time.

## The prompt does not change

`[A] Acknowledge all` already promises "document as deferred and proceed with
close". It documented but never deferred. This makes `[A]` do what it says.
`[R]` and `[C]` stay abort paths. No "carry forward" option is invented — an
item that is not acknowledged simply keeps surfacing, which is the default.

## The marker lives inside the artifact

Not a ledger. The audit mints no ids and has no stable identity — `phase` is a
token that collides across directories, `file` for deferred items is a constant,
and identity otherwise degrades to the item's own prose after a lossy sanitizer.
Any ledger must re-derive that key every close, so a reworded item silently
un-suppresses or, worse, mis-suppresses a different one. Storing the
acknowledgment next to the thing it suppresses makes that class of bug
structurally impossible, and it is the pattern `src/uat.cts` already argues for
with `deferred-items.md`'s in-place `status: resolved`.

## The marker is verdict-preserving and self-invalidating

`status:` is never overwritten — writing `resolved` into an unresolved UAT would
be a lie in the artifact of record, and the disclosure has to be additive.

    audit_acknowledged:
      milestone: v1.0
      at: 2026-08-15
      status: gaps_found      # snapshot of what was true when acknowledged

Suppression applies ONLY while the snapshot still matches reality: `status` for
seven categories, `question_count` for context questions, and for deferred items
a new per-entry `status: acknowledged` distinct from `resolved`, which keeps
meaning "actually fixed". Change the artifact and the acknowledgment stops
applying, so the item comes back on its own.

That is what makes re-opening answer itself with no extra state, and it fails in
the safe direction: a stale acknowledgment can never hide a NEW problem. A
malformed marker is treated as absent — a bad marker must never silence an item.

The check is ONE shared `isAuditItemAcknowledged`, not nine copies. This file has
already been through that defect family twice in this PR.

## Observable, not silent

`audit-open --json` now reports an `acknowledged` count beside `counts`, so a
reviewer can tell a close that is clean because things were fixed from one that
is clean because things were silenced.

## Writer

New `audit-open acknowledge` verb snapshots current state itself, so the marker
is never hand-authored from workflow prose — the gap that left the STATE.md
block with no writer, no schema and two conflicting formats. Writes route
through the existing path-confinement seam.

## Two deliberate limits, failing closed

Heading-delimited deferred entries (#3457) are REFUSED with
`unsupported_heading_shape` rather than edited, because mapping a heading entry
back to its exact source span is not safely derivable when headless and heading
entries interleave in one file. A loud refusal beats a mis-targeted write.

A quick task with no summary gets one created to carry the marker, since there
is otherwise nowhere to put it.

## Tests

Self-invalidation is the important one and is covered per category: acknowledge,
then change the status or question count, and the item resurfaces. Also
malformed markers not suppressing, `status:` byte-unchanged after acknowledging,
the writer refusing a path outside the project, and the four original #3458
scenarios unchanged.

Closes #3458

* feat(#3458): wire [A] to the acknowledge verb and converge the disclosure table

Consumer side of the suppression seam.

## The workflow stops hand-authoring the mechanism

`[A]` now calls `audit-open acknowledge` once per open item, then writes the
STATE.md `## Deferred Items` table as before. The table stays as a
human-readable disclosure; it is no longer the mechanism. That closes the gap
where the block had no writer, no schema and no reader — the marker is now
written by the tool, which snapshots current state itself.

The `[R]` / `[A]` / `[C]` prompt is unchanged, `[C]` still means "Cancel — exit
without closing", and no carry-forward option is invented.

The all-clear branch now distinguishes a close that is clean because items were
FIXED from one that is clean because they were ACKNOWLEDGED, using the
`acknowledged.total` count, and carries that into the MILESTONES.md disclosure
line beside the existing override count. A clean close that was bought with
acknowledgments should say so.

## Format drift resolved

Two incompatible `## Deferred Items` shapes shipped simultaneously — 3 columns
in the workflow, 4 in the template, with different body lines. Converged on one
5-column shape carrying the source Milestone, since archived items now appear
and the archived-milestone disambiguator was previously discarded at write time.
The workflow enumerates the categories instead of trailing off in `...`.

## Ack fragment bookkeeping

`complete-milestone.md` grows 6,764 bytes (31,228 → 37,992; cap 61,440), covered
by a new `tests/emitted-drift-acks/3458-*.json`.

`2962-zsh-nomatch-for-glob-portability.json`'s `complete-milestone.md` entry is
REMOVED — the no-duplicate-path rule hard-blocks two sources naming one path.
That entry is spent: the nullglob shim it acknowledges is present in both
`origin/next` and the CI emitted baseline `fd2b97a5`, so its ripple is already
absorbed and it can never clear anything again — verified directly, not assumed,
and the gate's own message directs deleting spent entries. Its other three files'
entries are untouched.

`scripts/sync-runtime-launcher.cjs` wanted to rewrite `explore.md` as well —
pre-existing drift unrelated to this change, reverted. `complete-milestone.md`
still carries exactly one canonical preamble.

Docs cover the verb's real flag surface, the marker's verdict-preserving and
self-invalidating behavior, and the new `acknowledged` count. A second `Added`
changeset covers the verb, since the existing `Fixed` fragment describes only
the archived-phase scanning.

Closes #3458

* fix(#3458): close three blockers in the acknowledgment seam

Adversarial review of the seam. Three BLOCKERs, one of which disproves a safety
claim I published in the PR body, the changeset and the docs.

## The claim was false; the code is fixed rather than the claim softened

I wrote that "a stale acknowledgment can never hide a NEW problem". It could.
`context_questions` snapshotted only the question COUNT, so replacing two
acknowledged questions with two brand-new blockers kept the item suppressed.
`uat_gaps` snapshotted only `status`, so adding five more pending scenarios
(`open_scenario_count` 1→6) kept it suppressed.

The snapshot now identifies CONTENT, not size: a digest of the whole question
set, and a status + open-scenario-count composite. Any edit invalidates. The
other seven categories were checked and their single tracked dimension is
already the whole story. Both disproofs now resurface the item.

## Writing to the wrong line, and reporting success

`acknowledgeDeferredItem` built an unanchored regex and exec'd it over the whole
file while match-selection and the ambiguity guard ran over the section body
only, so the write landed at the first match ANYWHERE. A file with `# Notes`
holding `- Fix the parser` above a `## Deferred Items` section holding the same
bullet: the CLI exited 0 saying `acknowledged: true`, injected `status:
acknowledged` under `# Notes`, and re-audit still reported the entry open. It
corrupted unrelated content, suppressed nothing, and claimed success — and since
`--file` is unconstrained the same path could inject into a UAT or VERIFICATION
body.

Matching is now anchored to the selected section, and the matched span is
re-verified against the selected entry before any write; a mismatch refuses with
`match_verification_failed` rather than writing.

## Acknowledging todos hid the ones never shown

`scanTodos` capped at five files and then checked acknowledgment. With seven
todos, acknowledging the five that were LISTED drove `todos: 0`,
`has_open_items: false`, and items six and seven never appeared in any later
scan. The workflow's own "repeat until no todos items" remedy terminates after
one pass. Pre-feature this was unreachable because the count was pinned at five.

That is silent over-suppression — the exact direction this PR exists to remove.
Acknowledged items are now filtered BEFORE the display cap, so unacknowledged
todos beyond it still drive the count.

## The [A] branch could not fail closed

Every acknowledge call sat in a `cmd | while read` pipeline with no status
accumulation, so any refusal was discarded and the close proceeded as
`override_closeout`. Separately, `io.output` swaps payloads over 50000 chars for
an `@file:<path>` sentinel — every `jq` would then fail, every loop body run
zero times, nothing be suppressed, and the close happen anyway.

Both closed: failures accumulate across all invocations and halt before close,
and the sentinel is dereferenced using the same pattern `verify_readiness`
already uses for `INIT_MANAGER`. Quoting was verified sound by the review and is
left alone.

## Also

Suppression is now visible in the human report, not only `--json` — the
"clean because fixed vs clean because silenced" distinction was promised for the
surface an operator actually reads.

The CRLF-preservation branches in the writer were dead: every `.md` write goes
through `_normalizeMd`, which normalizes line endings and blank lines whatever
the writer does. Deleted and documented rather than left as code that cannot run.

## Why these shipped

The review named it exactly: there was no coverage for
`unsupported_heading_shape`, `ambiguous`, `not_found`, duplicate-text
mis-targeting, todos beyond the cap, or CRLF. All are now tested, alongside both
snapshot disproofs and the mixed-section fixture.

* test(#3458): align the items-open footer wording with its assertion

Remote runner red on one test: the items-open footer must match
`/previously acknowledged item/i`.

The disclosure was NOT missing — the items-open branch already printed
"N additional items previously acknowledged and still suppressed." The word
order simply did not match the regex the test in the same change asserts. A
wording mismatch between my own test and my own implementation, not a behavior
gap.

Reworded to "N previously acknowledged items also suppressed above the M open
items", which satisfies the assertion and states the relationship between the
two counts more plainly than the original did.

Swept `formatAuditReport` for other branches that could skip the tally: the only
early return is the all-clear path, which already discloses it. `scan_error`
sentinels are filtered per category and excluded from `counts.total`, so an
all-error project falls through to that same branch. No inconsistency remains.

* fix(#3458): splice by carried span, digest the untruncated question set

Security review of the writer. Both findings are the same shape, and both are
cases where an earlier fix of mine was incomplete in the same direction: a value
derived for DISPLAY was reused for an IDENTITY or LOCATION decision.

## Writing to the wrong entry, again

The previous fix anchored matching to the `## Deferred Items` SECTION but still
re-found the entry inside it with an unanchored regex, so the write landed at
the first SUBSTRING occurrence rather than the entry's own span. The
`match_verification_failed` guard could not catch it, because the mis-targeted
span is byte-identical to the target.

Probe-confirmed, in a cloned repo's own artifact:

    - CRITICAL unfixed auth bypass
      see also: - minor typo
    - minor typo

Acknowledging "minor typo" appended `status: acknowledged` into the CRITICAL
entry, suppressing it at every future close, while the typo stayed open — exit
0, `"acknowledged": true`. A variant where the target text appears inside
unrelated prose split that line mid-sentence, acknowledged nothing, and still
exited 0, so the workflow's `ACK_FAILURES` halt never fired.

Fixed structurally rather than with a better regex: `splitGapsEntriesWithSpans`
carries each entry's own character span out of the splitter, and the write
splices by that recorded span. The location is already known at selection time —
re-deriving it by searching was the entire defect class. Added as a sibling so
`splitGapsEntries`' three existing callers are untouched. With index-splicing,
`match_verification_failed` becomes a genuine independent cross-check instead of
a guard that could never fire.

## The digest was blind past the third question

`deriveOpenQuestions` truncated to three questions, and clamped each to 200
chars, BEFORE the digest hashed it — so the snapshot could not see the fourth
and later. Ship three innocuous questions, acknowledge, then add real blockers,
and they are permanently invisible: measured `open=0, acknowledged=1`, report
"All artifact types clear."

That is the same self-invalidation property this digest was added to guarantee
one revision ago. The digest now covers the untruncated list; truncation is
display-only.

Found while fixing it: the previous digest joined on a literal raw NUL byte
embedded in the source — collisions are constructible, and reachable through
attacker-controlled YAML `\x00` escapes. Verified both ways. Replaced with a
length-prefixed encoding so no two question sets can collide by concatenation.

## Sweep

Because this is the third incomplete fix on this seam, every identity and
location derivation was swept for the display-vs-identity confusion: uat_gaps
uses status plus a full-content count, the other seven categories use a scalar
status or presence, the deferred `--text` identity is never truncated, and all
five flat categories resolve their file by path rather than by content search.
No further instances.

* test(#3458): correct two assertions that over-reached the measured behavior

Remote runner red on two of the F1 tests. The source is correct — reproduced
both fixtures against the built CLI — and both failures were bugs in the
assertions I wrote. `src/` is untouched by this commit.

The first is worth recording. It computed the CRITICAL entry's block as

    content.slice(content.indexOf('- CRITICAL'), content.indexOf('- minor typo'))

and `indexOf` found the FIRST SUBSTRING occurrence, which lives inside that
entry's own continuation line `  see also: - minor typo`. The block was
truncated mid-line, so the assertion could never match. The test committed the
exact first-substring-match mistake it exists to catch, one revision after that
mistake was fixed in the source.

The second asserted `deferred_items === 0` after acknowledging the typo entry,
but the decoy `- Note: reference - minor typo elsewhere, ignore` is itself an
open entry and was never acknowledged, so the correct count is 1. It now also
asserts WHICH item remains open — that is what actually proves the right entry
was suppressed, and the original assertion would have passed even if both had
been silenced.

Both now derive their expectations from measured CLI output. A comment records
that the write seam normalizes markdown (`_normalizeMd` inserts a blank line
before a list item following a non-list line) so the inserted line is not later
mistaken for a regression; that is repo-wide behavior for every `.md` write
through the single write projection, not something this change should diverge
from.

Root cause of both: the previous two dispatches verified behavior with direct
CLI probes but never executed the test file, so assertions could over-reach what
had actually been measured. Every other assertion added in those two commits has
since been re-derived from real output; no further mismatches.

66ad3d6250 test(#3523): rewrite two undetected source-greps as behavioral tests (#3548)
* test(#3523): rewrite two undetected source-greps as behavioral tests

Both sites read a real shipped hook and text-searched it, and both were
invisible to local/no-source-grep because the path was bound to a separate
const the rule never resolves back to its literal.

tests/check-update-config-dir.test.cjs carried three such reads, not the
one the issue cites. All three are replaced by a harness that runs the
real hooks/gsd-check-update.js under a fake HOME and observes the config
dirs detectConfigDir resolved, via the env the hook hands its worker.
Coverage now includes the CLAUDE_CONFIG_DIR precedence cases and the
full adjacent-pair search order the deleted static grep only asserted
for one pair.

tests/security-prompt-injection.security.test.cjs asserted the scanner
hook's SOURCE TEXT contained each canonical MARKDOWN_LINK_PATTERNS regex
source. It now drives probes through the real hook and asserts the
emitted ruleId, with a completeness gate so a new canonical pattern
without a probe fails loudly, plus safePredicate parity the text grep
never checked.

No allow-test-rule marker is added. The now-false marker on
check-update-config-dir.test.cjs is removed and its identity-allowlist
entry pruned, which the ratchet requires.

* feat(#3523): emit typed findings IR from the read-injection scanner

The scanner built a structured findings array internally and discarded the
structure when rendering its advisory sentence, so the only thing a test
could assert on was that prose. CONTRIBUTING's 'Prohibited: Raw Text
Matching on Test Outputs' names that exact situation and prescribes adding
the typed surface rather than matching the text.

findings is now an array of {ruleId, match} records and the advisory is
derived from it through a single renderFinding mapper, so the rendered
text and the IR cannot drift. The array is emitted additively on
hookSpecificOutput for both the advisory and blocking output shapes.

The advisory string itself is unchanged, byte for byte: verified across
six payload shapes (single markdown-link hit, 3+ finding HIGH, invisible
unicode, unicode tag block, injection-pattern-only, mixed) by running the
pristine and modified hooks against identical stdin and comparing. 28
existing assertions across four suites substring-match that string.

The #3523 parity assertions now read the IR, and a new test binds the two
surfaces together by asserting every MD-LINK ruleId in findings appears in
the advisory and that the reported pattern count matches findings.length.

Refs #3464

* docs(#3523): document the read-injection scanner output contract

The scanner had no subsection under Security Hooks, only a one-line table
row. Documents its trigger events, severity thresholds, skip conditions,
rule ids, and the findings IR added alongside the advisory.

Refs #3464

* fix(#3523): bind every finding family to the advisory, freeze rule ids

Two review findings on the typed-IR commit.

The parity test filtered on MD-LINK- and so bound only one of the four
finding families to the rendered advisory; the other three were covered
only by the pattern count, which catches a length mismatch but not wrong
text. It now drives a payload producing all four families at once,
asserts all four are present so it cannot silently degrade, and checks
each one's expected rendering against an expectation table coded
independently of the hook's own mapper.

The three synthetic rule ids were written twice each — once at the push
site, once in renderFinding — so a rename at one site would fall through
the generic render branch with no signal. They are now a frozen RULE_IDS
constant referenced from both. No string value changed; the advisory
remains byte-identical across all six proof payloads.

bc557f6876 chore(#3520): ratchet on effective exemptions, track unverified separately (#3529)
Phase 5 of #3464, following #3465, #3466, #3502 and #3508. Those cut the
ceiling 305 -> 278, made the rule accurate, and ended file-wide amnesty. This
one fixes the number itself.

scripts/lint-allow-test-rule-refs.cjs counted FILES CONTAINING MARKER TEXT.
Only 5 of those files carry a marker that actually suppresses a violation the
rule detects, across 10 sites. The ratcheted number was ~98% noise, which is
exactly why bumping it was frictionless: the metric was never coupled to the
thing it claimed to govern. That is the whole complaint this epic opened with,
stated precisely.

Verified directly rather than assumed: only eslint-rules/no-source-grep.cjs
functionally honors the marker. Four other rule files mention allow-test-rule
in prose only, and no-raw-rmsync-in-tests.cjs:24 explicitly states it does not
apply. So the large count was not legitimately large because several rules
share the annotation.

Now two numbers, only the first ratcheted:

  EFFECTIVE EXEMPTIONS -- markers that actually suppress a detected violation.
  10 sites across 5 files. Tightly ratcheted in both directions, as before:
  over the ceiling fails, and slack beyond grace fails.

  UNVERIFIED MARKERS -- marker-bearing files with no detectable violation. 273
  files. Reported and given a loose ceiling so the pool cannot silently
  balloon, but deliberately NOT tightly ratcheted, because shrinking it is a
  rule-coverage problem and not a delete-the-markers problem.

A file with at least one effective site counts as effective and is not also
counted as unverified; the two numbers never double-count.

Reporting ONLY the effective count was considered and rejected. It would say
five files and look excellent while being falsely reassuring, because "no
detectable violation" is not "no violation". This phase's own measurement found
two genuine source-greps that are unsuppressed AND undetected --
tests/security-prompt-injection.security.test.cjs:852 and
tests/check-update-config-dir.test.cjs:91 -- each reading a real shipped file
and text-searching it, invisible only because the path is bound to a separate
const the rule never resolves back to its literal. Markers guarding that class
count as zero-effective and would look vestigial. Trading a number that is too
big and meaningless for one that is too small and falsely reassuring is not
progress, so the script prints the known-limit caveat alongside the numbers and
the two undetected violations are filed separately rather than lost.

Single source of truth is structural, not a matter of discipline. The script
does not re-implement detection or the site-scoped adjacency predicate -- that
is the generative-fix-divergence class this repo has shipped before. The rule
now exports MAX_MARKER_LOOKAHEAD_LINES, MARKER_COMMENT_RE,
collectMarkerAndCommentLines and isSuppressedAt (extracted verbatim, no logic
change), plus a default-off neutralizeSuppression option so the counter can
enumerate every site through the real rule via ESLint's Linter API and then
classify each with the rule's own predicate, replicating reportUnlessSuppressed's
search-line-OR-read-line check exactly. Default rule behavior is byte-identical:
tests/eslint-rules.test.cjs passes 168/168 unchanged. A parity test asserts the
script's suppressed/not verdict equals the rule's own report/no-report outcome
for every site in a fixture corpus.

A real silent-failure bug surfaced and was fixed while building this: ESLint's
flat-config Linter reports "No matching configuration" and returns ZERO messages
for any filename resolving outside its cwd. That would have quietly
misclassified every sandboxed test fixture as having no violations -- a test
suite that passes while asserting nothing. Fixed by anchoring the Linter to the
tests dir, with a defensive throw if it ever recurs.

Two earlier claims of mine are corrected by this phase's measurement. Widening
the source-dir allowlist to include hooks/ -- the "fifth blind spot" recorded in
#3508 -- rescues ZERO sites; it is real in principle and has no practical
effect, because the hooks reads that exist are missed for other reasons
(.sh extension, identifier-indirection, dynamic filenames). And the #3508
correction that attributed those reads to the hooks/ gap rather than to variable
indirection was itself incomplete: both are independently sufficient, so fixing
either alone changes nothing. I accepted the reviewer's causal claim as
uncritically as I had made my own.

The unverified count is 273, not the ~289 in the phase design doc. That is
legitimate drift -- the baseline was measured at fba7c9032 and other merged work
has since removed markers. Left as measured rather than adjusted to match the
document.

Adversarial review found a BLOCKER in the first revision and it is fixed here.
The counter walked only tests/**/*.test.cjs, but the rule is registered on
tests/**/*.cjs -- every .cjs, not just test files -- plus scripts/**,
eslint-rules/**, bin/lib/**, pi/**, examples/**, gsd-core/bin/** and three
plugin globs. 35 non-.test.cjs files under tests/ were never walked, and
tests/helpers/live-command-registry.cjs:1 carries a real marker that appeared in
NEITHER reported number. A counter that undercounts is worse than the
meaningless one it replaces, because it will be trusted.

The scan set is now derived programmatically: the script dynamically imports
eslint.config.mjs and extracts the `files` globs from every config block that
enables local/no-source-grep. There is no hardcoded list to drift, which is the
same divergence class the parity test already guards.

Two further defects surfaced while fixing it. The silent-clean catch around
linter.verify() was worse than reported -- ESLint signals a parse error by
returning a message with fatal:true rather than throwing, so the original catch
would not even have fired for the common case. Both paths now throw with the
file path. That silent swallow was actively hiding a broken fixture in this
suite's own tests: 'no marker here\n' is not valid JS and the case only
"passed" because the parse failure was discarded. Fixed.

And once the scan widened, the raw-text marker scanner started matching this
tooling's own doc comments and RuleTester fixture strings, so marker extraction
moved to AST comment nodes. That corrected three long-standing FALSE POSITIVES:
allowlist entries for tests/eslint-rules.test.cjs that were never real markers,
only fixture payload. Allowlist 137 -> 135: three false positives pruned, one
real entry added for live-command-registry.

The headline numbers are coincidentally unchanged (10/10 effective across 5
files, 273/280 unverified) but the composition is corrected: one real file
gained, one phantom dropped. Verified by direct diff rather than inferred from
the totals matching.

The first remote run of this branch came back RED with 23 failures, all one
cause, and it is fixed here. Classification drove ESLint's flat-config Linter,
which resolves configuration relative to a cwd and refuses to lint any file
outside it. The test harness writes fixtures into an OS temp dir, so every
sandbox row hit "No matching configuration found" and tripped the defensive
throw. It surfaced only on the container because the repo lives at /work there
and the fixtures at /tmp, making the mismatch unmissable; a local run had
reported the suite green, which it was not.

Fixed by not depending on config *resolution* at all: the script now builds an
eslintrc-format Linter and registers the rule directly with defineRule, since it
already knows exactly which rule and options it wants. That removes the
cwd-ancestor constraint entirely and makes repo files and out-of-tree fixtures
classify identically. Verified out-of-tree explicitly, not just in-repo, because
the local temp path shape is what hid the bug the first time. Parse failures
still throw loudly -- that behavior is required and tested. Classifications are
unchanged for real repo files (10/10 effective across 5, 273/280 unverified,
0 live), which is the check that the config swap did not quietly alter results.

The second remote run cut the failures from 23 to 2, and the survivors were a
genuinely different and more interesting defect:
tests/packaging-shipped-scripts-require-only-shipped.test.cjs caught that
scripts/ SHIPS in the published package while eslint-rules/ does not, so
importing the rule for single-source-of-truth would MODULE_NOT_FOUND in a real
consumer's install. That test statically extracts require() calls, so hiding the
import inside a function would have dodged the check without fixing the problem.

Resolved along the grain of existing convention rather than by weakening
anything: package.json already excludes several repo-internal lint gates from
the shipped set via `!scripts/...`, including
`!scripts/lint-no-adhoc-regex-escape.cjs`, which is the same situation. This
gate is CI-only and has no meaning in a consumer install, so it joins them.
Verified with `npm pack --dry-run` that the .cjs is genuinely absent from the
tarball (its inert JSON config files remain, and carry no requires).

The third remote run failed on shard 3/3 across all three OSes with exit code
NULL and empty output -- the spawned gate was killed by a timeout, not failing
an assertion. Cause: replacing a raw text scan with a full ESLint Linter pass
over every file in every registered glob took the gate from 0.57s to ~7-12s,
and GitHub's runners are slower than the bench that had just passed it green.

Fixed by narrowing the work rather than raising the timeout to hide it. Both
numbers the gate computes are properties of files that CONTAIN a marker, so
only those (~294) need linting; the repo-wide byte walk that finds them stays,
since that was the undercount fix. Live violations in files carrying NO marker
are already enforced by npm run lint over exactly these globs, so re-detecting
them here was redundant. 2.87s now, from ~7s measured locally.

That narrowing changes what one reported number means, so the wording changed
with it: "live violations in marker-bearing files: 0 (unmarked files are
enforced separately by npm run lint)". A number that quietly covers less than
it reads is the failure this whole epic is about, so it is stated rather than
left implicit, and the test row that asserted the old broader behavior was
split -- an unmarked live violation now passes this gate (and is caught by
eslint), while a live violation in a marker-bearing file still fails it.

The repo-baseline test's timeout was also raised to 30s with a comment, since a
gate that legitimately takes ~3s must not sit at a timeout close to its own
runtime. Every other row keeps the shorter sandbox-scoped timeout.

Closes #3520

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.

8a6d87538f test(#3466): replace 8 source-grep assertions with behavioral tests (#3500)
Phase 2 of #3464, following #3465. Rewrites every assertion that read a
shipped .cjs/.js file and text-searched it, so the file no longer needs an
allow-test-rule exemption. 6 of the 8 files are now marker-free; the ceiling
drops 285 -> 278 against a measured 277.

A source-grep passes when a STRING is present, not when the code WORKS. It
survives a refactor that keeps the string but breaks the behavior, and breaks
on a refactor that keeps the behavior but renames the string. Both failure
modes are silent about the thing the test claims to protect. That is the
anti-pattern ADR-456 and local/no-source-grep exist to prevent.

Rewrites, each against the real exported seam:

- discuss-mode: calls cmdInitPlanPhase() against a fixture whose config sets
  workflow.text_mode, asserts the value propagates to its emitted JSON.
- effort-surface-axis: runs review-lane invoke against a real project with a
  fake `claude` PATH shim, asserts the resolved --effort actually lands in the
  shim's captured argv.
- install-minimal-hooks: calls applySettingsJsonHooks() with a hook source
  missing, asserts it is neither registered nor silently registers wholesale,
  with sibling present hooks as the positive control.
- install: calls the exported inferPreferredRuntime({fs, env,
  preferredConfigDir}) via its injected fs seam, asserting 'kilo' from both
  the config-marker and env-var paths.
- opencode-permissions: spawns the real installer with a custom config dir,
  asserts the written opencode.json permission paths are anchored on it.
- repo-layout: spawns the installer for copilot local vs global, asserting
  AGENTS.md is written only in the local case.
- runtime-config-adapter-registry: stubs resolveInstallPlan and force-reloads
  install.js, asserting the runtime's artifact stops being written -- proving
  install.js genuinely routes through the registry.
- runtime-homes-descriptor-drive: calls buildAgentSkillsBlock() for cursor and
  claude against real fixture SKILL.md files, asserting each runtime's refs
  land under its own config dir and never the other's.

Every rewrite was mutation-checked before its marker was dropped. Because
node --test is not runnable locally in this repo, each assertion was
replicated in a standalone probe that requires the same module: run green
against the real file, then red against a deliberately broken one (text_mode
propagation deleted, existsSync guard removed, config dir hardcoded, !isGlobal
guard dropped, kilo branch removed, effort resolution bypassed, skills base
hardcoded back to .claude), then the production file restored and confirmed
byte-identical. An assertion that could not be made to fail would not have
shipped -- a behavioral test that passes regardless of correctness is strictly
worse than the source-grep it replaces, because it looks rigorous while
asserting nothing.

Three claims were checked rather than trusted. All three were wrong:

- repo-layout's own marker cited #1188 asserting the `!isGlobal` lexical scope
  was "unprovable at runtime". It is provable: the guard decides whether
  AGENTS.md is written, which is directly observable. Both directions verified.
- The triage for runtime-config-adapter-registry claimed its source-grep was
  redundant with the file's EXPECTED_TABLE tests, so deletion would be safe.
  Those tests only exercise resolveInstallPlan() directly and never load
  bin/install.js, so they do not cover it. A real behavioral assertion was
  written instead of deleting coverage.
- An earlier revision of this change dropped runtime-config-adapter-registry's
  two markers on the grounds that ESLint stayed silent without them. An
  adversarial review caught that this was wrong, and it is restored here. The
  file still genuinely source-greps bin/install.js at two sites; ESLint is
  silent only because no-source-grep's TEXT_METHODS omits matchAll. Dropping a
  marker because the linter cannot see the violation is exploiting the blind
  spot, not resolving it -- and it would go red the moment the rule is
  widened. Those two assertions are also irreducible: they assert that EVERY
  inline `runtime === '...'` branch in install.js names a registry-known
  runtime, and a branch naming an unregistered runtime would simply never
  execute, so no runtime observation can prove its absence. The markers now
  say so explicitly.

Two coverage gaps in no-source-grep surfaced while doing this, recorded on
#3464 rather than fixed here, since widening the rule is its own change with
its own blast radius:

- TEXT_METHODS omits matchAll, so a matchAll source-grep never trips the rule
  (the case above).
- The path test requires a literal quoted bin/lib/gsd-core/src segment and
  tracks the binding one hop, so a read through a dynamic path or an
  intermediate variable evades it. install-minimal-hooks' genuinely
  load-bearing read at line 975 is itself unmarked for a related reason.

install-minimal-hooks therefore keeps its markers too: its remaining real
source-grep of bin/install.js (the Codex legacy gsd-update-check migration
check, line 975) is outside this issue's 8 sites. It is the last blocker for
that file and is a clean follow-up.

Closes #3466

895d9df96d fix(#3477): run untrusted key_links patterns on a linear-time engine (#3496)
`cmdVerifyKeyLinks` compiled `must_haves.key_links[].pattern` from plan frontmatter with `new RegExp()` and tested it against whole file contents, so a nested-quantifier pattern such as `(a+)+$` hung `verify-phase` indefinitely (CWE-1333). JavaScript has no regex-execution timeout.

Untrusted patterns now run on RE2 (re2js), whose match time is linear in input length — the class is closed by the engine, not by a heuristic screen. The screen lost in the ADR-0174 consolidation was deliberately NOT restored: it never worked, since `(a|a)*$`, `((a+))+$`, `(a+){2,}$` and `(a{1,3})+$` all evade it. A refused pattern's matcher returns false for every input, so it cannot report a match no matter what the caller does.

The engine is vendored at gsd-core/bin/lib/vendor/re2js.cjs because gsd-core/bin/** is copied into installed trees with no node_modules; runtime dependencies are unchanged. New ESLint rule local/no-external-require-in-bin enforces that invariant, which had been documented in a comment since the #3024/#2071 bug class and enforced nowhere.

Backreferences and look-around are unsupported by RE2 by construction — disclosed in a Changed changeset.

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.

* chore(#3468): backfill pr number in changeset fragment

5b5d473e13 chore(#3465): remove 22 verified-vestigial allow-test-rule markers (#3494)
Phase 1 of #3464. Removes the `// allow-test-rule:` marker from 22 test files
where it is provably vestigial, and tightens the ratchet ceiling in
scripts/lint-allow-test-rule-refs.ceiling.json from 305 to 285.

Eligibility is decided by two independent AST discriminators, both
conservative (any doubt => keep):

(a) Read-target type. Every readFileSync/readFile call in the file resolves
    statically to a prose/config extension (.md/.json/.yml/.yaml/.toml/.txt),
    or the file performs no reads at all. Any read of a source extension
    (.cjs/.js/.mjs/.ts/.cts/.mts/.jsx/.tsx), any dynamic/unresolvable path,
    and any other extension all disqualify the file.

(b) Marker context. Every `allow-test-rule:` occurrence is a genuine comment
    node, never string- or template-literal payload. A marker that lives
    inside a RuleTester `code:` fixture is test DATA, not a suppression
    directive; stripping it corrupts the test. tests/eslint-rules.test.cjs is
    the one such fixture host and is deliberately untouched.

An earlier attempt at this phase classified markers by "strip it and see if
local/no-source-grep still passes" and was reverted in full before commit.
That oracle is unsound: the rule only fires on a literal .cjs/.js/.ts path
containing a quoted bin/lib/gsd-core/src segment, tracked one hop from the
binding, so files that genuinely source-grep real JavaScript pass it
silently -- tests/no-unbounded-spawn-allowlist.test.cjs (reads test sources
through a listTestFiles() walk) and tests/claude-imperative-reference.test.cjs
(matches bin/install.js through an intermediate variable) both cleared it
while being real source-greps. The rule's implementation is narrower than its
intent, so it cannot adjudicate whether an exemption is load-bearing.

Scope is limited to comment deletions: the diff over the test tree is 100%
line removals with zero insertions, and no executable line is altered.

On the ceiling value. The measured count at this HEAD is 283, so 285 leaves 2
slack -- deliberate, and well inside the documented grace band of 3. Pinning
the ceiling to the exact count makes this change effectively unmergeable: any
concurrent PR that lands one marker-bearing test file re-reds it. That race
fired twice while preparing this branch (once mid-rebase taking the count
304->305 on next, once between rebase and the verification run taking it
282->283), and it is the same race that broke next in #3461. A ceiling of
actual+2 preserves a merge window while still ratcheting 305 -> 285.

Known limit, disclosed rather than papered over: this clears 22 of 303
markers and does not reach #3464's trend-to-zero goal. Most of the remaining
markers sit on dynamic-path reads, commonly a hoisted `const p =
path.join(tmpDir, 'STATE.md')` whose target is prose but is unresolvable to
this classifier. A stricter one-hop const resolution would flip an estimated
95 more; that is deliberately left to a follow-up so it can be reviewed on
its own evidence.

Marker discovery reads bytes rather than shelling out to grep:
tests/security-prompt-injection.security.test.cjs carries a literal NUL byte
(an intentional injection fixture) that makes grep treat it as binary and skip
it, which is why the true marked-file count is 303 and not the 302 a shell
scan reports.

Closes #3465
