80de48c319 enhance(#3914): every phase records a truthful guard ledger (#4018)
* fix(#3914): retire n/no-process-exit where its successor governs

Epic #3889 criterion 5 — no phase closes with a guard added and its
predecessor left standing — is violated in the tree by the epic that wrote it.

local/require-registered-exit was registered on gsd-core/bin/**/*.cjs and
scripts/**/*.cjs, while n/no-process-exit stayed 'error' over a nine-glob block
covering those same two. Only the hooks 'off' exemption ever came down; the
predecessor's registration never did. Both rules have been enforcing the same
property on the same surfaces since P6.

Narrowed, not deleted. Seven of those nine globs have NO successor —
eslint-rules/, bin/lib/, pi/, examples/, vscode/, .kilo/, .opencode/ — so
deleting the rule outright would silently drop enforcement on all seven. That
is the inversion this epic has already hit three times: removing a coarse guard
because a narrower one exists somewhere it does not reach. Flat config is
last-match-wins and both successor blocks come after the nine-glob block, so
'n/no-process-exit': 'off' in exactly those two retires the predecessor
precisely where the successor governs and nowhere else.

The successor is strictly more precise: it permits process.exit only inside
terminateNow in cli-exit.cts, the single sanctioned terminator (ADR-3889 §3),
where n/no-process-exit permits none and would flag terminateNow's own
generated copy.

Asserted at the consumer's altitude via ESLint.calculateConfigForFile on real
paths, with the positive control that matters: n/no-process-exit is still
'error' on six of the seven successor-less globs, so a future edit that turns
this into a blanket disable goes red. bin/lib/ has no file in this checkout and
is reported as untested rather than given an invented path. Severity is
normalized across the string/numeric/array forms the API can return, and the
normalized value asserted — not truthiness.

Verified by running calculateConfigForFile myself on both superseded globs and
four controls before trusting the test.

Found and fixed inline: the change made an eslint-disable directive at
gsd-tools.cjs:257 partially unused, which --max-warnings 0 rejects; narrowed to
the one rule still in force.

Verification runs on the remote runner.

* docs(#3914): the epic added three guards, it did not remove one

The audit reconciled the epic ledger against what actually landed. The net is
+3, not -1: four lint:generated-sync --check arms (gen-scripts-cli-exit,
gen-hooks-cli-exit, gen-exit-code-registry, gen-exit-code-docs) plus one rule,
against two retirements.

An epic whose thesis was consolidation ended with a larger guard surface than
it started with. The additions are each defensible; the claim that the total
fell was never true.

Two of the three prior errors in this amendment are mine. It said "Net -1 by
count" above terms reading -1 -1 +1 +1 +1, which sums to +1 — an arithmetic
error in the paragraph directly below the sentence arguing that an ADR about
honest accounting must not pad its own ledger. And the term list omitted two of
the four --check arms, which is what turns that +1 into the real +3.

Recorded rather than quietly rewritten. This ledger has now been wrong three
times — the original -2, the -1 that replaced it, and #3914's own table, which
states -1 above terms summing to 0 — and a written claim nobody checked against
the thing it describes is the exact failure this epic exists to close.

Refs #3914

* fix(#3914): make the successor actually supersede before retiring the predecessor

An isolated security review found that the previous commit turned off a guard
that was still doing work. Reproduced by executing both rules against a
fixture, not inferred:

  const exit = 'exit';
  process[exit](1);

n/no-process-exit flags it; local/require-registered-exit did not, because it
early-returned on callee.computed. So retiring the predecessor on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs un-guarded that shape on precisely
the two globs this epic's exit contract cares most about.

This is the third time in this epic I have removed a coarse guard on the claim
that a narrower one covered it, without checking construct-level parity — after
the allowlist key-to-prefix-to-exact-membership sequence and the band
ranges-to-categories one. The rule is the same every time: a narrower guard
supersedes a coarser one only where it demonstrably reaches at least as far,
and "demonstrably" means executing both against the constructs, not reading
either.

The successor now resolves computed property access for the statically
determinable cases — a string Literal, and an Identifier bound once to a string
Literal, resolved through scope — and leaves genuinely dynamic properties
alone so the rule does not over-fire. Measured after the fix: plain
process.exit flagged, process['exit']() flagged, process[exit]() flagged,
process[globalThis.k]() not flagged. That makes it a strict superset of the
predecessor on these globs, since process['exit']() was caught by NEITHER rule
before.

The second finding is worse than the first, because it was reasoning rather
than oversight. My justification comment claimed n/no-process-exit "would flag
terminateNow's own generated copy here". It would not — that file is in the
global ignore list, so neither rule ever lints it. There was no conflict to
resolve; I wrote a rationale I had not checked, in a change whose entire
subject is written claims nobody verified. Both comment blocks now state the
real basis.

The tests that should have caught this asserted only rule SEVERITY per glob and
never construct REACH, which is exactly how a coverage hole passed. A parity
matrix now pins all five shapes, including a RED/GREEN regression pin against
an inlined reproduction of the pre-fix rule — inlined rather than loaded from
HEAD, because HEAD resolves to the fixed commit under the remote runner and
would silently stop testing anything.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the two exit rules are complementary — keep both

Reverts this branch's retirement of n/no-process-exit. The premise was wrong
twice, and the second review proved the change itself was wrong.

I claimed local/require-registered-exit was a strict superset on
gsd-core/bin/**/*.cjs and scripts/**/*.cjs. Measured, successor vs predecessor:

  function f(exit) { process[exit](1); }         0  vs  1
  let exit='exit'; exit='exit'; process[exit]()   0  vs  1
  const { exit } = ...; process[exit](1)         0  vs  1

plus for-of bindings, let-then-assign, var redeclaration, catch params, and an
undeclared global named exit. The predecessor matches any identifier NAMED
exit however it is bound; the successor resolves only a string literal or a
single-write const. It never was a superset — I asserted the relationship after
fixing one construct and did not re-check the rest.

The justification was independently false: all three generated cli-exit copies
are in the global ignore list, so n/no-process-exit was never flagging
terminateNow. There was no conflict to resolve. I wrote a rationale I had not
verified, in the phase whose subject is written claims nobody checked.

So criterion 5 does not apply to this pair. They are not predecessor and
successor — they are complementary, each catching constructs the other misses.
The epic's criterion assumed a replacement relationship that does not exist
here, and retiring either rule loses real coverage. The ADR ledger now says so
with the measured shapes.

What survives is the genuine improvement: the computed-property strengthening.
local/require-registered-exit now catches process['exit'](1) and optional-chain
terminators like process?.[k]?.(1), which NEITHER rule caught before, while
correctly ignoring a genuinely dynamic property so it does not over-fire.

The parity tests are rewritten to assert what is true rather than what I wanted
to be true: a bidirectional matrix where each rule is shown catching shapes the
other misses. The previous matrix tested only the four shapes where the
successor wins, which is precisely why the regression shipped — a test set
selected to confirm the thesis.

Also corrected: a stale ADR sentence claiming a third wrong ledger version that
does not exist (the table it described now reads +3 over terms summing to +3),
and a changeset whose stated motivation was the false generated-copy conflict.

Verification runs on the remote runner.

Refs #3914

* fix(#3914): the exemption term was a no-op — the net is +4

Fourth correction to this ledger, and a fourth error of the same kind.

Every version counted removing the n/no-process-exit 'off' entry from the hooks
block as -1. Measured: calculateConfigForFile returns undefined for that rule on
hooks/**. It was never registered there, and no broader block sets it globally,
so the 'off' entry overrode nothing and removing it changed no enforcement at
all. A no-op removal, not a guard removal — the same category error as counting
baseline acknowledgement entries: a thing that is not a guard, in guard units.
It is misattributed too; that block came down in d98b55562 (#3910), already on
next before this branch existed.

So the epic added FOUR guards, not three.

This surfaced from a test of mine that overclaimed. I asserted n/no-process-exit
was error on "all nine CommonJS/hook globs" — but hooks is not one of the nine,
and the rule resolves to undefined there. Fixing the test to match reality is
what exposed the ledger term, which is the argument for tests that assert
identity rather than a comfortable shape.

The hooks state is now pinned explicitly rather than glossed: n/no-process-exit
unregistered, local/require-registered-exit error. It is mildly surprising and
therefore worth a test.

Also updates a pre-existing test that documented the old name-based-only
boundary as intentional. The computed-property strengthening deliberately moves
that boundary — process['exit'](0) was caught by NEITHER rule before — so the
test now asserts the new contract and cites the ADR, rather than being left to
fail or the rule weakened to satisfy it. A contract change should read as
deliberate in the test that pins it.

Verification runs on the remote runner.

ab69b9ce56 enhance(#3987): guard slug re-derivation and the swallowed-precondition shape — §8.5 was guardable after all (#3999)
* feat(#3987): guard slug re-derivation, and record why the swallow shape cannot be guarded

Epic #3473's Decision 1 requires the wrong call site be UNREPRESENTABLE. #3984
measured that two of the nine §8 rules had no guard at all and recorded both as
"Shipped - test-covered". This closes one of them, proves the other cannot be
closed the same way, and corrects two false claims I merged yesterday.

1. §8.3 - scripts/lint-slug-derivation-drift.cjs.

   generateSlugInternal (src/core-utils.cts) is the canonical owner; #3883 removed
   11 inline copies. Nothing prevented a twelfth: no slug guard existed in
   scripts/ or eslint-rules/.

   The detector is STATEMENT-scoped and matches the shape the real copies took -
   one statement carrying BOTH .replace(<negated class>, '-') and
   .replace(/^-+|-+$/, ''). Statement scoping is what buys the precision: the
   loose LINE-level form yields 18 hits with 7 unrelated, a material
   false-positive rate. Measured on the tree: 5 flags, 2 TRUE, 3 SANCTIONED,
   0 FALSE.

   The three sanctioned sites are allowlisted with a reason each, following
   lint-phase-enumeration-drift's form rather than a bare denylist. The owner
   itself is listed explicitly even though it escapes by construction - an
   implicit escape is a latent bug, and the next person to touch line 192 would
   not know the guard depended on it.

2. Both TRUE positives were live defects, not style.

   scripts/qa-smell-ratchet.cjs reproduced the canonical formula including the
   60-cap but trimmed BEFORE truncating - the #2849 bug - and never
   transliterated. The divergence is total, not cosmetic:

     canonical  "privet-mir-privet-mir-privet-mir-privet-mir-privet-mir-prive"
     inline     "tail"

   Cyrillic collapsed to nothing and only the ASCII remainder survived, so the
   ratchet was keying on wrong identifiers for any non-ASCII input.

   tests/planning-inspect.test.cjs carried a helper whose comment claimed parity
   with getPhaseDirFromPhaseId. That function now transliterates; the helper did
   not, so the test asserted against a stale formula while looking correct. Both
   now route through the seam.

3. §8.5 - measured, and deliberately NOT shipped.

   A candidate detector (swallowing catch + errno-retry-set test in the same
   function) gives 26 flags across 11 functions: 0 TRUE, 26 FALSE. Every one is
   best-effort unlink/rm/close cleanup, lost-rename-race backoff, or a deliberate
   null fallback. The file-scoped variant is worse at 71.

   Worse than the noise: the only known true instance was removed by #3885, so
   there is NO POSITIVE CONTROL - the guard cannot be shown capable of failing,
   which this repo requires of every drift guard. Shipping it would add a guard
   nobody can trust and nobody can test.

   The ADR now records the measurement and the reason, keeps §8.5 at
   "Shipped - test-covered", and points at the #1884 regression test as what
   actually enforces it. An honest "not detectable at acceptable precision" beats
   a guard that only ever passes.

4. Two claims I merged into the ADR yesterday were wrong.

   §8.9 said 17 of 19 subsumed children have a test citing their issue number,
   and that #3364 and #3812 have none. Both halves are false, and the claim came
   from a NUMBER-GREP - inside an amendment whose own subject is that a text match
   is not a fact.

     #3364 IS cited: tests/runtime-marker-resolution.test.cjs:107,
       T3 installMarkerResolvesWhenEnvAndConfigAbsent_3897 (#3364), asserting at
       :115-119.
     #3812 IS covered: tests/gen-state-md-docs.test.cjs:374, asserting at :382.

   Corrected to 19 of 19.

   #3812 does carry a real finding, though a different one: it is PARTIALLY
   DELIVERED on a CLOSED issue. The shipped fix declares cardinality for
   frontmatter keys, but #3812's stated acceptance was about the
   ## Current Position BODY section, and docs/reference/state-md.md:196-208 still
   has no normative single-valued/overwrite sentence and no pointer to
   ## Performance Metrics for history. Recorded in the ADR and left for #3812 to
   re-open - fixing it here would bury a scope question inside an unrelated PR.

Note on B6: this ADDS a guard, and B6 said the net count must fall. #3951 already
amended that clause - a guard ledger is a claim about COVERAGE, not count - which
is what makes adding this one honest rather than contradictory.

Verified: the guard flags 0 on the fixed tree, and PROVES IT CAN FAIL - a fresh
inline copy planted in src/ makes it exit 1 naming the exact statement. All three
sanctioned sites were confirmed exempt BY the allowlist, not by accident of the
pattern, by re-attributing each to a non-exempt path and watching it flag.
build:lib, lint and lint:ci all exit 0.

* fix(#3987): §8.5 IS guardable — I was wrong, and the guard found a live defect

Two orthogonal reviews. The correctness review overturned my central judgment,
and it was right.

1. I concluded §8.5 was "not detectable at acceptable precision" and recorded
   that in the ADR. False.

   My evidence was 26 flags / 0 TRUE / 26 FALSE. The reviewer pointed out what I
   had not: all 26 false positives are CLEANUP verbs - rmSync 54, unlinkSync 43,
   closeSync 17, chmodSync 12 - and the obvious narrower predicate was never
   tried. A swallowed cleanup is legitimate best-effort. A swallowed CREATION is
   a precondition silently lost, which is exactly the #1884 shape.

   Measured properly, in three stages:
     swallowing catch                                     911
     + try-block calls a CREATION verb                     24
     + enclosing function references a *_ERRNOS set         0

   0 flags, 0 false positives. The `*_ERRNOS` naming key is empirically total -
   all 10 retry/tolerate sets in src/ follow it.

   My second claim was worse. I wrote that no positive control exists because
   #3885 removed the only true instance, so the guard "cannot be shown capable of
   failing". That is self-refuting: this very PR's slug guard proves-it-can-fail
   on a synthetic tree, and the pre-#3885 blob is available as exactly such a
   fixture. It is now the control, and it works in both directions - the rule
   flags 0c43d853e^:src/planning-workspace.cts at line 210, the line the fix
   commit's own message cites, and reports zero on the post-fix code.

   I stopped at the first negative result on the option that meant less work.

   Shipped as eslint-rules/no-swallowed-precondition.cjs, wired into the existing
   src/**/*.cts ESLint block rather than a scripts/lint-*-drift.cjs: no script in
   scripts/ requires typescript/espree/acorn, and scripts/ ships to consumers, so
   a .cts-parsing standalone guard would add a devDep at consumer runtime. The
   ESLint block already parses .cts for free.

2. The guard immediately found a live defect of the same class.

   src/capability-lock.cts swallowed a mkdirSync on the lock directory, then
   acquireLock classified the follow-on failure as `code !== 'EEXIST' → return
   null`. A real EACCES/EROFS makes openSync(lockPath,'wx') fail ENOENT, which is
   not EEXIST - so a fatal filesystem error was laundered into "lock
   unavailable". Same defect as #1884, different laundering target.

   Fixed the way #3885 fixed #1884: the creation failure propagates. Regression
   test proven fail-first by hand - with the fix stashed, EACCES was laundered to
   null; restored, it throws.

   The strict rule does NOT catch this shape (its errno classification is an
   inline literal, not a named set). The rule is deliberately left strict: the
   broadened form had 2 false positives - capability-lock.cts:408, the deliberate
   EEXIST steal protocol, and commonjs-marker.cts:131, which returns a distinct
   documented outcome. The gap is noted in code rather than papered over with a
   noisy predicate.

3. The security review found the slug guard's exemption FAILED OPEN.

   currentFunction was never reset, and only a column-0 `function` declaration
   updated it, so exemption bled from an allowlisted declaration to the next one.
   generateSlugInternal exempted 50 lines for an 11-line function. A
   re-derivation planted anywhere in that window was silently exempt - the same
   fail-open shape that produced a blocker in #3897, and an allowlist is a
   SUBTRACTION so a mismatch fails open by construction.

   Extent is now tracked by real brace depth, and a test plants a violation after
   each allowlisted function's real closing brace and asserts it IS flagged.

4. Also from the security review: the guard was a CI-DoS and narrower than I
   claimed.

   Its unbounded [^\]]* was re-scanned from every `.replace(/[^` start: 54.3s on
   a 1.28MB line. It imported MAX_REGEX_LITERAL_LEN and never called
   readRegexLiteralAt - the bounded tokenizer that exists for exactly this. Now
   routed through it with a 2MB file cap: ~200ms.

   15 of 25 genuine re-derivations evaded. Widened to catch replaceAll, {1,},
   \s*-wrapped classes, escaped ], literal new RegExp(...), five trim spellings,
   .split().join(), and multi-line .replace( args - still 0 false positives.
   Two forms still evade and are documented as deliberate gaps with negative
   tests: the two-statement/temp-var form and new RegExp built from a variable.
   Both need data flow, and guessing at it is how a guard becomes noisy.

   Also fixed: // inside a string truncated the line, a ; inside the collapse
   regex split the statement (a one-character bypass), and SCAN_EXT omitted
   .mjs/.tsx/.jsx.

5. A regression I introduced, caught by the same review.

   qa-smell-ratchet.cjs top-level-required a build output that is not
   git-tracked, so the script hard-failed MODULE_NOT_FOUND before build:lib -
   including for --help, which previously had no build dependency. The require is
   now lazy at the point of use.

6. Four of my own tests were vacuous or weak.

   T9's input yielded an identical string under the buggy formula, so it passed
   on the implementation it was meant to catch. T12 compared maxLen null vs 60 on
   an 18-char name, where they agree trivially. T9-T12 all asserted
   generateSlugInternal directly, so they would pass unchanged if both call-site
   fixes were reverted. And prove-it-can-fail was scoped to scanRepo, never the
   CLI - dropping main()'s exit-code line would have kept every row green.

   All rewritten with discriminating inputs, per-call-site rows that red when the
   fix is reverted, 59/60/61 boundaries, an entirely-non-alphanumeric row, and a
   CLI row asserting the real subprocess exit code and both sanitizeForReport
   sites.

Verified: both guards flag 0 on the tree and both prove they can fail. The
swallow rule's control is confirmed in both directions - pre-#1884 shape flagged,
post-#3885 shape clean. build:lib, lint and lint:ci all exit 0.

* docs(#3987): record that §8.5 IS guardable, and correct a correction that made a ledger worse

Three ADR corrections, two of them to text this branch wrote hours ago.

§8.5 advances to Enforced. Its previous entry said the rule was not detectable
at acceptable precision. That was wrong twice: the 26 false positives were
uniformly CLEANUP verbs, which is a reason to narrow the predicate rather than
abandon it, and the claim that no positive control exists was self-refuting - the
pre-#3885 blob is available as a fixture and this repo's own guards prove-it-can-
fail on synthetic trees. Narrowed to creation verbs plus a *_ERRNOS reference:
911 -> 24 -> 0 flags, 0 false positives, control confirmed in both directions.
The entry keeps the wrong reasoning visible, because a high false-positive count
being evidence the predicate is wrong - not evidence the rule is unguardable - is
the transferable part, and the first negative result is most seductive when it is
also the answer that means less work.

§8.9's correction is itself corrected. The original 17-of-19 claim was CORRECT
for the predicate it stated; this branch silently swapped cited -> covered and
declared 19 of 19. #3812 appears in zero test files. Changing what a word means
to make a ledger read better is a worse failure than the miscount it claimed to
repair. Both predicates are now reported separately - 18 of 19 cited, 19 of 19
covered - because §8.9 asks for a test NAMING each child, so 18 is the number
that answers it. #3812 is also re-opened for real, rather than the first draft's
promise that it could be.

§8.3 stays Shipped - test-covered rather than advancing. The slug guard catches
the copy-paste class and a dozen variants, but two forms still evade by decision
(temp-var split, new RegExp from a variable) because both need data flow. Naming
them keeps the status honest: the wrong call site is much harder to write, not
unrepresentable.

* fix(#3987): replace my own wall-clock assertion, and close the guard that let me write it

CI went red on ubuntu shard 2/3. The failing test was mine, and the failure was
the test, not the code.

  a 1.28MB line ... scans in well under a second (was 54.3s pre-fix)  7368ms

It asserted ELAPSED TIME. ~200ms locally, 7.4s on a shared CI runner. The bound
introduced for the MAJOR-2 DoS fix works - 7.4s against a 54.3s pre-fix baseline
is the fix doing its job - but an absolute wall-clock threshold on shared
hardware is a race, not an assertion. CLAUDE.md says so directly: "Clock Seams:
Do not assert on wall-clock time." I wrote the anti-pattern the project bans, in
a PR about guards.

Raising the threshold would only move the flake. The row now asserts a
DETERMINISTIC bound instead: an instrumentation seam on drift-scan.cjs counts
readRegexLiteralAt calls and characters examined, and the test asserts
charsExamined stays under an absolute ceiling. Measured on the same 1.28MB
fixture: 120,000 calls, 48,000,000 chars - two orders under the ceiling. The
pathological fixture is kept; only the thing being asserted changed.

Proven to still discriminate: with MAX_REGEX_LITERAL_LEN raised to simulate the
unbounded pre-fix behavior, the same fixture does not complete in 120 seconds,
versus ~0.3s bounded. It is a real regression test, not a tautology.

Then the second half, which is the same defect class as the rest of this PR.

  eslint-rules/no-elapsed-assertion.cjs matched only the EXACT identifiers
  ^(elapsed|duration|took|ms)$.

I used `elapsedMs`. It evaded the rule entirely. tookMs, durationMs,
elapsedTime and msElapsed evade the same way. A guard that cannot see the
violation it exists to catch is exactly what this PR is about - it just happened
to be an existing rule rather than one of the two I came here for, and it was
found because I committed the violation it should have blocked.

Widened to /^(?:elapsed|duration|took|ms)(?:[A-Z]\w*)?$/ plus a narrow
start/endMs delta pair. Deliberately NOT a blanket *Ms suffix: a first draft did
that and produced 2 false positives on `timeoutMs` in
plan-phase-stall-detection, which is a configured timeout and not a measurement.
Verified negative on params, items, forms, terms, dirnames, timeoutMs,
cacheTtlMs and staleAfterMs.

Measured over the five files carrying camelCase timing identifiers: 0 true
positives beyond my own, so nothing else needed rewriting. The rule's own test
file gains a row asserting `elapsedMs` flags, proven to fail against the
pre-widening rule - the same prove-it-can-fail standard both new guards in this
PR are held to.

* fix(#3987): a comment I added leaked a Claude reference into every runtime install

The runner went red with 4 failures in tests/install.test.cjs:

  Leaking: .hermes/scripts/lib/drift-scan.cjs
  Leaking: .qwen/scripts/lib/drift-scan.cjs

The instrumentation seam added for the deterministic bound carried a comment
naming CLAUDE.md as the source of the no-wall-clock-assertions rule. scripts/
SHIPS to consumers, so that comment was installed verbatim into hermes and qwen
trees, and the install suite scans for exactly this - a Claude-specific reference
reaching a non-Claude runtime.

The rule is real and worth citing; the filename is not portable. The comment now
says "this repo's test rules" and states the rule inline, which is what a reader
of an installed tree actually needs anyway.

Worth noting what caught it: not lint, and not the two guards this PR adds - the
install suite's full-tree scan, which exists precisely because a shipped file is
read by runtimes that have never heard of CLAUDE.md. Same lesson as the rest of
this PR from the other direction: the check that matters is the one that can see
the surface where the defect actually lands.

* fix(#3987): a test fixture swallowed 46 git exit codes and produced a silent false negative

CI red on ubuntu shard 3/3:

  tests/health-validation.test.cjs:2029
  expected exactly one W024, got [{"code":"W006", ...}]

Not caused by this branch, and the evidence is decisive rather than a hunch: the
SIBLING test at :2039 builds the IDENTICAL fixture with the identical
commitsAhead and asserts the same thing, and it PASSED in the same process, same
file, same run. Same input, both outcomes - which rules out logic, ordering,
sharding and environment, and leaves a per-invocation nondeterministic failure
inside one fixture build.

The mechanism is an unchecked exit code, 46 times over. The W024 fixture performs
~46 runGit spawns and never checks a single one. runGit returns failures as DATA
and never throws, so one silently-failed `git commit` yields 19 commits instead
of 20, or a silently-empty `git rev-parse HEAD` yields a blank state_head. Either
drops readStateHeadFreshness below the advisory threshold, W024 never fires, and
only W006 remains.

Reproduced exactly: 20 commits -> ["W006","W024"]; 19 -> ["W006"]; blank
state_head -> ["W006"] - byte-identical to the CI assertion dump.

The arithmetic is what hid it. At threshold-1 and threshold+1 a lost commit still
produces the asserted answer; only the exactly-at-threshold cases sit one commit
from a false negative. Two of the seven tests are in that position, and CI hit
one. That is why it had never been seen before, and why it surfaced now: this
branch adds three test files, which reshuffles the cost-weighted shard partition
and moved this file into a chunk where the latent flake fired.

My files were checked as suspects first and cleared: all fixtures mkdtemp-unique,
no process.chdir, no .planning/ writes, no git spawns, and node --test gives
per-file process isolation regardless.

Fixed at the cause, not the symptom. A mustGit wrapper throws on a non-zero exit
with the command, exit code and stderr, and all nine call sites route through it.
The fixture now asserts its OWN preconditions before the assertion under test
runs - the seed head is non-empty, and `git rev-list --count <seed>..HEAD` equals
the requested commitsAhead - so a fixture that did not build what it claims fails
loudly as a FIXTURE ERROR naming got-versus-asked, instead of quietly handing a
weaker input to the assertion.

Proven: dropping one commit now raises
  FIXTURE ERROR: requested commitsAhead=19 but git rev-list --count reports 18
where it previously produced a silent ["W006"] pass-for-the-wrong-reason. 64/64
tests in that block pass unperturbed.

Deliberately NOT done: no threshold change, no retry, no loosened assertion, no
skip. The assertion was correct; the input was silently wrong.

Worth naming, because it is the same shape from the other side: this PR ships
eslint-rules/no-swallowed-precondition.cjs, whose entire subject is a swallowed
precondition failure being laundered into a plausible downstream outcome. This
fixture is that defect in test code - the swallowed git failure was laundered
into a legitimate-looking "W024 did not fire". The rule does not cover test
fixtures, so the connection is noted at the fix site rather than enforced.

* fix(#3987): two tests wrote to committed files; the shard packing decided when that mattered

CI red on windows-latest shard 1/3 only:

  "gen-exit-code-registry: CLI" > "a --write run redirected to a tmpdir leaves
  every committed artifact untouched"
  AssertionError: hooks artifact must be untouched

The Linux runner passed the same sha at 40425/40425. It is Linux-only, so a
Windows-scheduling defect is structurally invisible to it.

Root cause, established by measurement rather than inference.

tests/cli-exit.test.cjs appended a corruption marker to the REAL COMMITTED
hooks/lib/exit-code-registry.js, held it corrupted across a full subprocess, and
restored it in a finally. tests/exit-code-registry.test.cjs reads that same real
file before and after its own subprocess and asserts byte equality. If it samples
while the other test holds the file corrupted, it fails. The landmine is
pre-existing, from 2ea5efc15 (#3911).

What this branch changed is WHEN the two run together. scripts/run-tests.cjs
shards by cost-weighted LPT over the sorted unit list, so adding three test files
repacks the bins:

  merge-base c3e667df3 (838 files): cli-exit -> shard 1, exit-code-registry -> shard 3
  HEAD       03b342601 (841 files): BOTH in shard 1, same argv chunk, one
                                    node --test process, concurrent

Co-location is necessary but not sufficient - Linux shard 1/3 also had both and
passed. Windows loses because TEST_CONCURRENCY defaults to 2 there against 4
elsewhere, spawn cost is ~10x, and the sibling corruptor holds one of only two
slots through a ~90s tsc compile. That turns a sub-second overlap into seconds.

Not a path-separator or case-sensitivity issue, and not CRLF - .gitattributes
pins * text=auto eol=lf. Redirection was not at fault either: ensureScriptsOut
derives all five --out flags correctly and gen-exit-code-registry.cjs honours
them with no __dirname escape.

Fixed at the cause: no test writes to a committed file any more. Both corruptors
now copy to a mkdtempSync tmpdir, corrupt the COPY, and point the generator at
it. Repinning or reordering the shards would have turned CI green while leaving
the landmine armed for the next reshuffle.

That required closing an inconsistency between two sibling generators.
gen-exit-code-registry.cjs already accepts
--out/--scripts-out/--hooks-out/--dts-out/--sh-out and honours them under
--check; gen-hooks-cli-exit.cjs hardcoded OUTPUT_PATH and had no flag surface at
all, so its corruptor could not be redirected anywhere. It now takes --out in the
same style, honoured by both --write and --check, and is a no-op when absent -
verified: a bare --check on the default path still exits 0.

ensureScriptsOut moved to tests/helpers/exit-code-artifact-flags.cjs and both
test files import it. Hand-rolling a second copy of the flag derivation would
have been a re-derivation of exactly the kind this PR ships a guard against.

Verified: both tests still detect corruption (proven by defeating the check and
watching them red, with a positive control showing an uncorrupted copy exits 0);
SHA-256 of hooks/lib/exit-code-registry.js and hooks/lib/cli-exit.js identical
before and after running both rewritten bodies, and git reports nothing under
hooks/ modified - that is the property that was violated. A repo-wide search for
the corrupt-then-restore-in-finally shape against hooks/ found no other
instances.

One detail worth recording: the tmpdir test keeps --declaration pointed at the
real committed declaration rather than copying it, because the generated banner
embeds path.relative(REPO_ROOT, declarationPath) - copying it would produce a
false drift unrelated to the injected corruption. The declaration is read-only on
that path and never written.

12f9d1d9a0 enhance(#3913): docs, and the guards come down (#3994)
ADR-3889 terminal phase. Generated docs/reference/exit-codes.md from the exit-code declaration with a --check drift arm; deleted the inert soft-error-exit-zero oracle; promoted untyped-success from SMELL to VIOLATION so it can fail a build; pruned all 5 smell-baseline entries.

Fixed inline: two mis-scoped oracles (routing-validity, value-hygiene), a second source behind the band table, unescaped declaration strings reaching Markdown, and a pre-existing Windows 8.3 short-name path-comparison defect.

Guard ledger corrected from a claimed net -4 to a measured net -1.

* enhance(#3624): local/no-exact-case-env-access — ratchet ADR-1703 onto production env reads (epic #3411 Phase 4)

Extends ADR-1703's portability rule catalog with a second production-runtime
rule: it flags an exact-case read of a Windows case-varying environment
variable (PATH, PATHEXT, ComSpec, USERPROFILE, TEMP, TMP, APPDATA) off any
receiver that is not process.env itself, matched via an env-shaped-receiver
check to avoid colliding with ordinary `.path`-named properties elsewhere in
the tree.

Exports the seam's private `_envGet` as `envGet` so the rule's remediation
message names a real helper, and fixes the one pre-existing violation the
tightened rule found (`src/runtime-hooks-surface.cts`'s `env.APPDATA` read).

Closes #3624

* fix(#3624): extractStaticName recognizes non-computed Literal destructuring keys; add missing accessor-call test case

Review findings from the code-review + isolated-adversarial passes:
- extractStaticName only matched non-computed Identifier keys, so a
  destructuring like `const { 'PATH': v } = opts.env;` (the issue's own I8
  acceptance case) silently evaded the rule. Widened to accept a Literal key
  regardless of computed, which is safe for MemberExpression too (its
  non-computed property is always an Identifier by grammar).
- Added the missing RuleTester valid case for "a case-insensitive accessor
  call" (envGet(env, 'PATH')) from the issue's Done-when checklist.

bb4f3073c0 docs(#3984): give every §8 rule its delivered status and its measured executor (#3986)
Surfaced by an /adr-phase-coverage audit of epic #3473 after its last sub-issue
merged. §8 is the epic's declared source of truth - "where this section and the
code disagree, the code is the defect" - and line 136 defines a per-rule status
vocabulary.

Not one of the nine rules was ever advanced past its pre-implementation status.
The word Enforced appeared exactly ONCE in the document: in the sentence that
defines it. Three rules read "Required - phase unassigned" for work that Phases
5, 7 and 8 demonstrably delivered, so a reader auditing coverage today would
conclude three of the nine contract rules had no owner. That is the orphan shape
this epic exists to eliminate, sitting in the epic's own contract, and it is the
same defect class as B6's guard ledger: a status column is a claim, and it was
false.

Flipping all nine to Enforced would have repeated the mistake inverted. Decision
2 says a declared policy with no executor is a loud failure, so Enforced asserts
an executor EXISTS - and measurement found the nine are not equally enforced. The
vocabulary is now three values:

  Enforced              a standing guard wired into lint:ci or CI fails the
                        build; a new wrong call site cannot land
  Enforced (structural) the wrong call site is unrepresentable
  Shipped - test-covered  delivered and regression-tested, but NO standing
                        guard; a regression in covered code is caught, a new
                        wrong call site elsewhere is not

Measured per rule, with the executor cited:

  8.1 Enforced             lint-vendored-deps + no-external-require-in-bin
  8.2 Enforced (partial)   phase-enumeration-drift covers the sentinel arm; the
                           #3357 resolver arm is test-covered only
  8.3 Shipped              NO guard for slug or marker re-derivation
  8.4 Shipped              structural for argv; no guard for the general rule
  8.5 Shipped              the delivering change added zero guard scripts
  8.6 Enforced (structural) the transaction type; state-write-path-drift
  8.7 Shipped              structural via reconcileReportedFields; no guard
  8.8 Enforced             gen-state-md-docs --check in lint:generated-sync
  8.9 Enforced (prospective) lint-fix-has-regression-tests fires on NEW fix
                           commits; it does not assert the 19 children are
                           covered. 17 of 19 have a test citing their number;
                           #3364 and #3812 have none - a text match, not proof
                           the behavior is uncovered, but not evidence it is
                           covered either

The third status value is not a euphemism for done. It names precisely where this
epic's own thesis - make the wrong call site unrepresentable - is NOT yet
achieved. §8.3 and §8.5 are the thinnest: nothing today stops a twelfth inline
slug copy or a second silent swallow.

Also corrects a claim this ADR made three days ago and #3977 has since overtaken.
The ledger amendment concluded #3426/#3239 "need new detectors". The measurement
behind that was right - the glob widening structurally could not reach them - but
the prescription was not the best available: #3977 rerouted the test's parsers
onto the ADR-2143 seam, so there is no ad-hoc parse left for a detector to find.
Removing the violation beat teaching the rule to see it. Both issues are CLOSED;
the roster row and the amendment now say so, and say why the earlier conclusion
should not be built on.

Closes #3984

d24e22b156 enhance(#3912): gsd-tools declares outcomes, pinned at v1 (#3983)
* enhance(#3912): gsd-tools declares outcomes, pinned at v1

ADR-3889 §4. Phase 6 already moved error()'s terminator onto the seam, so what
remained was the declaration — and the pin that makes it invisible today.

The census corrected two documented figures before any code changed.
ERROR_REASON has exactly 25 members (the ADR and epic were right; an earlier
note of mine claiming 23 was wrong and is corrected). And output({error}) is
**64 sites across 9 files, not the 60 ADR-2980 ratified** — the module shape
holds but the total drifted +4: frontmatter 7 not 6, phase 4 not 2, roadmap 3
not 2. That matters because this phase's criterion demands the pin be asserted
over the enumerated population rather than sampled; asserting over a stale 60
would leave four sites unpinned while claiming full coverage, which is the
shape of failure this epic exists to remove.

The issue does not state the fact that shapes the design: output() never
touches the exit code. Confirmed by reading it — it writes fd 1 and returns.
So a declared outcome for those 64 sites had nowhere to be READ. The mapping
was never the work; wiring somewhere for the declaration to land was.

The seam already existed twice over. cli-exit.cts holds two globalThis-Symbol
cells, each because the module is emitted to three locations and a module-level
`let` would let instances disagree, and runMain already maps a code returned by
main(). A third cell inherits that solution. output() records DEGRADED for any
{error} payload — key-order agnostic, which is exactly why the "42 sites"
figure undercounts — and runMain projects the cell only when main() returns
nothing, so an explicit return still wins.

error() maps its reason through a table over the closed 25-member enum, leaving
all 278 call sites untouched; 226 of them pass no reason at all. The version
gate lives in error(), NOT in projectOutcome: registered names are
version-invariant there, so mapping a reason straight through would make USAGE
project to 64 under v1 and break the pin on its first line. projectOutcome is
left exactly as Phase 2 shipped it, DEGRADED's 0/80 asymmetry included.

Proven rather than asserted. v1 is byte-identical across three real CLI paths —
config-get plain, config-get --json-errors, and an output({error}) path —
matching exit code and exact bytes against the pre-change build. Under
GSD_EXIT_CONTRACT=v2 the same commands now exit 66 (CONFIG_KEY_NOT_FOUND ->
NO_INPUT) and 80 (DEGRADED), both looked up through the registry. An
anti-vacuity test pins that v1 and v2 genuinely differ for at least one reason,
because without it a mapping where everything projects to 1 under both versions
would satisfy every other assertion and the declaration would be theatre.

A1 iterates all 25 enum members and A3 asserts over the measured 64-site
population, so a 26th reason or a 65th site fails until it is given a mapping —
the drift guard this phase needs, given ADR-2980's own count had drifted +4
unnoticed.

Verification runs on the remote runner.

Refs #3912

* fix(#3912): the outcome cell must never lower an exit code

The remote run caught a fail-open that this phase introduced, in the phase
whose entire purpose is removing fail-opens.

`state validate --strict` on a missing STATE.md exited **0** where it must exit
1. Mechanism: `runMain` projected the pending outcome whenever `main()` returned
void, and under v1 DEGRADED projects to 0 — so a `process.exitCode` already set
non-zero by the command was clobbered down to success. Confirmed live against a
fixture, before and after.

This refutes a review conclusion recorded earlier in this phase, that the cell
was "fail-closed and can never mask a failure as success". It could, and did.
Recording that plainly so the assumption is not repeated: the cell's danger was
never only that it might add a failure — it was that projecting it
unconditionally overwrites whatever decision came before.

Projection is now guarded: it may set a code only when none is set, and an
already-non-zero exit code always wins. The full precedence — explicit `main()`
return, then an existing non-zero exitCode, then the declared outcome — is
written at the projection site. A regression test drives a void return with a
pre-set non-zero code and a pending DEGRADED, and fails against the pre-fix
build.

The second failure was my test encoding the wrong contract, not a code defect.
It asserted `output({found:false, error: undefined})` records DEGRADED because
the KEY is present. `JSON.stringify` drops undefined, so the payload the user
receives is `{"found":false}` — carrying no error at all, and calling that
degraded would hand back exit 80 under v2 for output that reads as clean. The
discriminator is a serializable error VALUE, not key presence. The test now
pins `{error: undefined}` as explicitly NOT degraded, and the design doc's
wording is tightened to match.

Verification runs on the remote runner.

Refs #3912

* docs(#3912): the versioned exit contract, and a flag defect the docs found

Diataxis pass for Phase 8, plus a real fix that only surfaced because writing
the how-to meant running its own examples.

The docs. ADR-2980's "Revisit if" clause asked for exactly the versioned
projection this phase provides, so it gets an amendment naming #3912 /
ADR-3889 section 4 as that boundary: v1 stays 0 byte-for-byte, v2 projects
DEGRADED to 80. The amendment also records the count drift rather than
restating a stale figure — the ADR ratified 60 output({error}) sites in 9
modules; the AST-measured population is 64 across the same 9 (frontmatter 7
not 6, phase 4 not 2, roadmap 3 not 2). The pin is asserted over the
enumerated 64. json-errors.md gains the outcome-declaration reference,
including the precedence order a review pass got wrong and the suite refuted:
an explicit main() return, then an already-set non-zero process.exitCode, then
the declared outcome. Projection may only ever set a code, never lower one.

A how-to is owed here and is written, not skipped. Under v1 nothing changes,
so the audience is an operator opting into v2 and needing to know what the
codes mean for a CI gate — a migration, which is how-to shaped. It covers
turning v2 on, the code table, why 80 is "ran and reported a condition" rather
than a crash, and how to split a gate that treats any non-zero as fatal. No
tutorial: there is no new entry point to learn, and under the default contract
a reader would be walked through observing nothing.

The defect. Running the how-to's own Step 1 example returned

    $ gsd-tools --exit-contract=v2 state validate --strict
    Error: Unknown command: --exit-contract=v2          (exit 64)

while the same flag trailing the subcommand worked and exited 80. The flag
half-worked, by argv position. resolveContractVersion scans argv
non-destructively, so the token survived into the dispatcher, which treats
argv[2] as the command name. --json-errors had already solved precisely this
at gsd-tools.cjs:4455, under a comment naming the hazard verbatim: "The argv
splice must happen here too, otherwise the dispatcher below sees
--json-errors as an unknown command." The later flag never got the same
treatment.

Fixed rather than documented around: the version is resolved first — which
memoizes the cell and makes an invalid value throw early — and then every
--exit-contract= token is spliced out of the dispatcher's argv copy.
--exit-contract is now listed in TOP_LEVEL_USAGE, where it never was. The
regression test pins leading position, trailing position, agreement between
the two, and a loud failure on v3 rather than a silent fall back to v1.

Neither review engine would have caught this: the defect is invisible in the
diff, because the diff does not touch argv handling. It surfaced only from
running the documentation's own example. Writing a how-to is an execution pass.

Verification runs on the remote runner.

Refs #3912

* fix(#3912): the flag splice has to run before the run-with-timeout return

An isolated review of the previous commit found that the fix did not deliver
what it claimed, and that two of its own tests were weak. All three findings
reproduced by execution before any change was made.

The fix was placed below a return. main() intercepts `run-with-timeout` at
gsd-tools.cjs:4436 and returns from there — above both the --json-errors block
and the --exit-contract splice added in the previous commit. So the flag still
died in leading position for that one command:

    $ gsd-tools --exit-contract=v2 run-with-timeout 5 -- node -e "..."
    Error: Unknown command: run-with-timeout        (exit 64, child never ran)

The previous commit message and the test's describe-block both claimed
position-independence unconditionally. That was an overclaim, not a gap left
open, and it is the part worth naming: the fix was verified by hand on the
commands I happened to think of, and `run-with-timeout` returns before the
code I was verifying.

Both global-flag blocks now run above the interception, with a comment naming
it so a later edit cannot slide them back down. Moving --json-errors up fixes
the identical pre-existing bug for that flag, verified failing beforehand
(exit 1, sdk_unknown_command). Fixing the sibling is deliberate: same defect,
same block, and a known-broken twin next to a fixed one is not a resting state.

Two tests were not pulling their weight. The invalid-value test was vacuous —
it passed against the pre-fix build, because `--exit-contract=v3` already
exited 1 there and already printed the resolve error lazily through
error() -> getContractVersion. Both its assertions held before the fix, so it
pinned nothing. The real discriminator is that the pre-fix build emits BOTH
"Unknown command: --exit-contract=v3" and the resolve error, while the fixed
build emits only the latter; the test now asserts that absence.

The leading-position and leading==trailing tests asserted proxies — "not 64",
"no Unknown command", "the two agree" — none of which pin a value, and all of
which would survive both positions being identically broken. With a .planning
directory and no STATE.md, state-snapshot exits exactly 80 under v2 and 0
under v1 in both positions. Those numbers are pinned now. The multi-token case
the descending splice loop exists for is covered too, and run-with-timeout has
regression tests for both flags.

The lesson is narrower than "test more". Hand-verifying the production
behavior does not verify that the test would have caught its absence. The
pre-fix binary has to be run against the test's own assertions.

Investigated and deliberately not changed: splicing before --cwd parsing
degrades one diagnostic from "Missing value for --cwd" to "Invalid --cwd:
<path>", but that is pre-existing — verified on the pre-fix build via
--json-errors, which already did it. This change joins the pattern rather than
creating it, and both forms exit 64 on malformed input either way.

Verification runs on the remote runner.

Refs #3912

* chore(#3912): backfill changeset pr numbers to 3983

* test(#3912): pin the reason-table invariant as set equality, not a count

A graph-backed review flagged the unchecked lookup in
expectedErrorCode3912. Investigated by execution: the drift guard DOES
hold — for an unmapped reason under v2 the production error() yields 1
while the table yields undefined, so the assertion fails. Not a
correctness defect, and deliberately NOT made tolerant, since a tolerant
lookup would destroy the guard.

Two real problems remained. The guard asserted the wrong invariant: it
counted the TABLE's keys at 25 rather than checking they match the
ENUM's values, so a renamed member keeps the count at 25 and slips past,
and a 26th member leaves the table at 25 and slips past too. Both were
then caught only indirectly, by an undefined mismatch producing 'must
exit undefined'. It is now a sorted set equality, so the failure names
the specific missing or extra reason.

And the comment above it described a '?? FAIL' fallback that does not
exist anywhere in the function. It now states what the code actually
does, verified by running it rather than by reading it.

* feat(#3626): make CONTEXT.md seam claims checkable via SEAM.*.enforced-by gate

Adds SEAM.<id>.owns / SEAM.<id>.enforced-by=lint-rule:<name>|test:<path>
predicates to CONTEXT.md, generalizing the existing WORKTREE.SEAM.* shape,
plus scripts/lint-seam-enforcement.cjs (wired into lint:ci) which fails
when a declared single-owner seam names no existing, registered
enforcement mechanism. Backs all six current module-level single-seam/
single-canonical-owner claims found in CONTEXT.md, including the Shell
Command Projection Module's Windows-binary-resolution claim via #3619's
local/no-private-binary-resolution rule.

Scope is resolves-only per maintainer decision: the gate proves an
enforcement pointer exists and is registered, not that its surface
covers every file the seam claims. See docs/adr/3626-context-md-seam-claim-gate.md.

Closes #3626

* fix(#3626): back the Package Identity Module's seam claim too

Isolated adversarial review caught a miss in the "no grandfather list"
sweep: the Package Identity Module also declares itself "Single seam
owning GSD's published-package coordinates" and already names its real
enforcement (scripts/lint-package-identity-drift.cjs). Backs it with
SEAM.package-identity.owns/enforced-by=test:tests/package-identity.test.cjs,
bringing the total to 7 backed seams. Also makes explicit, in the design
doc and ADR, that function-level "single owner" sentences inside
already-covered modules (STATE.md Document Module, etc.) are deliberately
out of scope — a seam claim is about a module's boundary, not every
function inside it.

15af0f5536 enhance(#3951): B6+B7 — widen two unreachable lint rules and make the guard ledger true (#3965)
* fix(#3951): two lint rules that could not reach the code they govern

B6 names two widenings. Measuring them first turned up a defect the criterion did
not know about, and refuted the reason it gave for one of them.

1. no-adhoc-markdown-parsing self-gates on its own filename.

   Lines 107-110 short-circuit create() to {} unless the path matches
   /(?:^|\/)src\/[^/]+\.cts$/. B6 says to widen the files: glob in
   eslint.config.mjs - but doing only that ships an INERT rule, because the gate
   still returns {} for every new path. Both halves have to change, and the gate
   is the load-bearing one.

   That same regex hides a live hole: [^/]+ is FLAT-ONLY, so it requires the file
   to sit directly in src/. The registered glob is src/**/*.cts, which includes
   subdirectories. 28 .cts files - health-diagnostic-rules/ (10),
   installer-migrations/ (11), observability/ (3), host-integration-adapters/ (2),
   vendor/ (2) - are inside the registered glob and silently skipped.

   Measured with the gate neutralized: 0 violations there today. The hole is
   hiding nothing right now, and is fixed anyway, because "no violations today" is
   not a property that keeps holding.

   The fix is not invented: require-subprocess-timeout.cjs:196 already carries the
   correct form of this guard, /(?:^|\/)src\/.*\.cts$/ with .*, one directory over.
   Checked the other 21 rules for the same bug - no-adhoc-regex-escape and
   no-private-binary-resolution short-circuit only to exempt their own seam file,
   which is the right shape, and no-crlf-fragile-split has no filename gate at
   all. This bug is unique to the one rule.

2. no-adhoc-regex-escape could not see the shape that actually occurs.

   Line 396 gated the whole UNSAFE-NEW-REGEXP arm on arg.type === 'Identifier'.
   Every check below it - the _SOURCE provenance check, the
   isSoleReturnOfOwnParameter shape - lives inside that branch, so
   new RegExp(obj['key']) and new RegExp(cfg.pattern) were never examined at all.
   Runtime data arrives as a property access far more often than as a bare
   identifier, which is exactly why this rule never fired on the #3477 ReDoS.

   Widened to MemberExpression, measured by AST walk across all five registered
   blocks rather than by grep. 27 sites, zero TSAsExpression:

     18  safe new RegExp(X.source, flags)  -> exempted, keyed strictly on the
         PROPERTY being `source`, never on the object. Keying on the object would
         wave through X.anything and buy nothing. B6 estimated ~10; that was an
         undercount.
      3  _SOURCE-suffixed constants reached through a required module namespace
         (phaseId.BRACKET_PHASE_TOKEN_SOURCE) -> the same provenance-exempt class
         the rule already recognizes for bare identifiers, extended to reach them.
         Without this the widening produces 3 false flags.
      6  real findings -> marked, each a test extracting a pattern from a shipped
         file at test time, where the runtime contract IS the product.

   Deliberately the NARROW MemberExpression form. The rule's own
   isSoleReturnOfOwnParameter doc comment records that an earlier broad
   "any non-literal identifier" heuristic produced ~25 false positives and was
   rejected; a re-run of the census after this change flags exactly the 6 above
   and nothing else.

Verified by execution, not by reading: the gate now accepts src/<subdir>/x.cts,
still accepts flat src/x.cts, and still exempts paths outside src/ - each pinned
by a test proven to fail against the old regex. build:lib, lint and lint:ci all
exit 0.

* fix(#3951): give no-adhoc-markdown-parsing its reach, and fix the 80 parses it finds

The rule self-gates on filename AND is registered on one glob, so widening either
half alone is inert. Both move here: the gate now accepts tests/**/*.cjs and
scripts/**/*.cjs alongside src/**/*.cts, and eslint.config.mjs registers it on the
same two.

A test pins that the gate and the registration AGREE, in both directions. The
original defect was a gate narrower than its registration; the failure mode of
this fix is a gate wider than its registration. Both are silent, so the test
asserts the pair rather than either half.

80 violations across 43 files, all in tests/, zero in scripts/. 70 are routed
through the existing seams - scanFencedBlocks, collectSection, stripFencedCode,
tokenizeHeadings from markdown-sectionizer; splitTableRow, parseMarkdownTable,
findTableWithColumns from markdown-table. Headerless STATE.md tables use
splitTableRow per line, because parseMarkdownTable needs a real delimiter row.

10 are suppressed, 12.5%, well under the third that would have meant the rule is
mis-scoped for tests/ rather than the tests carrying debt. Each names its reason:
three regression guards (#3873 / bug-#21) are deliberately independent of the
generator's own fence handling, and routing them through the seam would have them
test the generator against itself; one is a negative-text probe that extracts
nothing; six are a shell-pipe-to-jq detector whose regex coincidentally matches the
table fingerprint and is not markdown parsing at all.

All ten sit in tests whose subject is .md content, which is normally a reason to
prefer the seam. The marker used is allow-adhoc-markdown, distinct from
no-source-grep's allow-test-rule, and lint:ci's lint-allow-test-rule-refs reports
the same 280/280 unverified count as before - checked rather than assumed, because
those two markers are easy to conflate.

The widening earned its keep immediately: it found a test that passed for the
wrong reason.

  tests/config-field-docs.test.cjs asserted notEqual(<cell>, '600') against the
  TYPE column instead of the DEFAULT column. notEqual('number', '600') is true
  forever, so the guard against workflow.subagent_timeout regressing to the old
  seconds default could never fire. docs/CONFIGURATION.md:434 is
  `| workflow.subagent_timeout | number | 300000 | ... |`, so the default is cell
  index 2; the assertion is now row-scoped through splitTableRow and reads 300000.

That is the argument for the widening in one case: the violation was invisible to
lint, the suite was green, and the assertion was vacuous. A rule that cannot reach
a file cannot tell you the file is lying.

Not fixed here, and recorded rather than assumed: #3426/#3239 are NOT reachable by
this widening. tests/package-legitimacy-gate.test.cjs yields zero violations even
with the gate bypassed - its hand-rolled scans are real, but built from line
filters and split('|') rather than the regex-literal fingerprints this rule
detects. They need new detectors. The epic assumed a wider glob would catch them.

build:lib, lint and lint:ci all exit 0; the post-fix census across tests/** and
scripts/** is 0 violations.

* fix(#3951): B7 — and #3356's defects were still live in the code

B7 asks that each closed child be driven fail-first with a behavioral identity
test at the CONSUMER's output. Four of eleven children had no test citing their
issue number. Auditing them by BEHAVIOR rather than by number-grep changed the
answer for three of the four.

#3364 and #2540 — traceability only. Both were implemented by #3941 and their
consumer-output tests exist and were shown failing-first; neither cited its
originating issue, so an audit that greps for the number reports them uncovered.
Tagged the specific asserting test in each file, following the citation form those
files already use.

#3372 — covered, but only at helper level, and the triage narrowed it. Of the four
commands the issue names, only estimate-cli's collectCalibrationSamples actually
enumerates phase dirs from disk; smart-entry, audit and roadmap-upgrade derive from
ROADMAP/body text and never reach the sentinel path, so they are benign by
construction and were left alone rather than "fixed" into churn. The existing #3882
rows asserted the helper's return value. Added a consumer-output test driving
`query estimate-calibrate` and asserting sample_count and the persisted document.
RED proof: reverted collectCalibrationSamples to a raw readdirSync and ran the real
CLI - sample_count 3, sentinel leaked; restored - sample_count 2.

#3356 — NOT covered, and BOTH halves of the defect were still live in source. The
issue is closed; the bug was not fixed. Fixed here rather than writing tests that
document a bug as correct.

  Defect 1, the contradicted row. quick.md:627 claimed
  `quick-tasks-append` performs "the equivalent write" to the Step 7c row. It did
  not: the `#` cell was a positional ordinal and `Directory` read `—`, because the
  route had no way to receive a quick id or task directory. Added OPTIONAL
  `--quick-id` / `--slug` / `--directory`. A caller with neither - fast.md, the
  original #2133 caller - omits them and gets the byte-identical prior row, so
  nothing existing changes. A caller that HAS a real id and directory now gets the
  canonical row quick.md:632 renders. The false-equivalence sentence itself is
  corrected rather than left to mislead the next reader.

  Defect 2, the forced re-derive. The route called readModifyWriteStateMd with no
  options, so a body-only append to the Quick Tasks table triggered a full
  re-derive of the disk-derived progress.* frontmatter. Every other body-only
  writer passes { resync: false } - src/state.cts's own docstring prescribes it -
  and this route was the lone outlier. RED proof: reverted the option, seeded a
  project with 2 real phase dirs and a curated total_phases of 25, ran
  quick-tasks-append; total_phases collapsed to 2. Restored; it stayed 25.

That second one is the shape this epic exists to close: a silent write that
replaces curated state with a re-derivation nobody asked for, exit 0 throughout.

build:lib, lint and lint:ci all exit 0.

* docs(#3951): amend B6's ledger to what was measured, and document the new flags

The ADR gains a ledger amendment in its own correction style - the sixth wrong
premise it records, found the same way as the other five, by measuring before
building.

B6 says the net guard count must fall. It rose: 62 -> 69, +7, measured from the
epic's filing commit to origin/next. The attribution is the point, though. Five of
the seven came from PRs unrelated to this epic, one was added by a phase of it, and
the epic did retire something sub-file - #3884 removed a detector with an explicit
"net: -1 detector, 0 added" ledger. Every named casualty is load-bearing, two
already carry retractions in this same document, and a sweep of all 22 rules plus
every scripts/lint-* found no provably dead guard. There is no honest way to make
the count fall; forcing it would trade coverage for a number, which is the Goodhart
outcome Decision 6 exists to prevent.

The amendment also records that B6's own prescribed fix for one widening was inert.
no-adhoc-markdown-parsing self-gates on its filename, so widening only the files:
glob - which is what the criterion says to do - ships a rule that still returns {}
for every new path. And #3426/#3239 are not reachable by that widening at all;
their scans use line filters and split('|'), not the regex fingerprints the rule
detects. The roster row tracked them against the wrong mechanism.

Three roster rows updated from aspiration to fact: the two widenings are DONE with
their measured counts, and lint-phase-enumeration-drift is marked RETAINED rather
than "expected casualty - verify before retiring", because Phase 5 verified it and
kept it.

The rule Decision 6 should carry forward is stated plainly: a guard ledger is a
claim about COVERAGE, not about COUNT. "Net count must fall" is measurable and
wrong. "Every guard is reachable, and each retirement names what makes its defect
unrepresentable" is the property that was actually wanted.

CLI-TOOLS.md documents the optional --quick-id/--slug/--directory flags and says
plainly that omitting them keeps the pre-#3356 row byte-identical, plus that the
append no longer re-derives progress frontmatter.

New features fragment (id 3951); FEATURES.md regenerated rather than hand-edited.
Changeset is Changed, pr:0 pending backfill.

* test(#3951): correct four rows that pinned the lint rule's old narrow reach

The remote suite came back RED with 5 failures, all in tests/eslint-rules.test.cjs.
They are stale tests, not a regression: four rows assert that
no-adhoc-markdown-parsing is inert outside src/*.cts, which is exactly the
contract this deliverable changes.

Confirmed by reading rather than inferred from the names - the row at :1981 used
filename: 'tests/some.test.cjs' and filename: 'scripts/helper.cjs', the two roots
the rule now covers on purpose.

Worth recording WHY local gates missed this. npm run lint and lint:ci were green,
and the touched test files passed standalone. Lint only reports violations in real
files; these rows assert the rule's REACH using synthetic RuleTester filenames, so
nothing but the full suite could see them. Local green on a rule change says
nothing about the rule's own tests.

Each row is rewritten with BOTH halves rather than flipped from valid to invalid:

  - the same fingerprint under tests/ or scripts/ is now flagged, with the right
    messageId
  - the negative space is preserved - the same fingerprint under a path outside
    all three roots (gsd-core/bin/lib/foo.cjs) is still NOT flagged

The second half is the one that matters. Without it the rule has no boundary and
nothing would catch an over-wide gate later, which is the mirror image of the bug
this deliverable just fixed.

Each row is renamed to state the current contract; the old names said
"non-src/*.cts ... is not flagged" and would have been actively misleading once
the bodies changed.

Proven to test the widening rather than restate it: every flagged half was run
against HEAD~2's pre-widening rule and does NOT fire there, then against the
current rule and does. 12/12 on that probe; the full file is 178/178.

Swept for the same staleness elsewhere and found none.
require-subprocess-timeout's own "inert outside src/*.cts" row is untouched -
that rule's gate was not widened here - and no-adhoc-regex-escape's test file
already carries correctly-targeted rows.

* test(#3951): acknowledge the quick.md growth the attribution guard reported

The full suite came back RED with one failure, and it is mine:

  1 file(s) grew without an acknowledgment:
    quick.md grew 364 bytes

gsd-core/workflows/quick.md is runtime-loaded emitted content, so correcting
its false 'performs the equivalent write' claim trips emitted-attribution by
construction. This is the acknowledgment, not a workaround - there is nothing
to regenerate.

The fragment names ONE path, which is the only one the guard reported. The four
spent acknowledgments it also listed (audit-uat, plan-phase, progress, review)
belong to other fragments whose ripple the base already absorbs; they are inert,
not failures, and are deliberately NOT copied here - naming paths I did not
change would make this record false in the other direction.

Byte figure corrected before committing: the guard reported 37220 -> 37584
(+364), but origin/next has since moved and quick.md is 37232 there now, so the
measured delta is +352. The reason text says so and names the base as a moving
figure rather than pinning a number that is already stale.

* test(#3951): move the quick.md growth ack to a trailer, delete the obsolete fragment

The acknowledgment mechanism changed under this branch. Merging next brought in
the redesign - it also deleted .github/workflows/ack-fragment-sweep.yml, which
was in the merge status and which I did not register at the time - and the guard
now says so directly:

  Add a trailer to a commit in this PR (never a new file).
    Emitted-Drift-Ack-Growth: quick.md - <why this growth is deliberate>

So tests/emitted-drift-acks/3951-quick-append-equivalence.json is obsolete on
arrival. A fragment file is no longer read by anything, and leaving it would be a
dead record that looks like an active one. It is deleted here rather than kept
"just in case".

The byte figure moved again with the merge: 37232 -> 37596, +364. The earlier
fragment said +352, measured before the merge auto-merged quick.md itself. The
trailer carries no number, which is the better design - the figure was stale
twice in two attempts.

Refs #3951

Emitted-Drift-Ack-Growth: quick.md — #3356/#3951 replaces a false claim with an accurate one. Line 627 said the `quick-tasks-append` shortcut "performs the equivalent write" to the Step 7c row rendered above it; it did not, and that was the documented half of #3356 — with no quick id or task directory the route emitted a positional ordinal in `#` and an em-dash in `Directory`, a visibly different row. The corrected sentence has to carry three facts the original elided: what the shortcut actually writes when it has neither input, that this is honest behavior for its real caller (`fast.md`, which has neither), and how a caller with both now gets the byte-identical canonical row via the new optional `--quick-id`/`--slug`/`--directory` flags. Prose is the product here — an executing agent reads this line to decide whether the shortcut is safe for its case, and a shorter correction would either drop the flags (leaving the reader unable to act on the fix) or drop the limitation (recreating the false claim in gentler words).

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.

Refs #3942

* 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.

Refs #3942

* 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.

Refs #3942

* 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.

9410f7e6e6 enhance(#3897): ADR-3473 §8.3 rungs 2-4 — runtime marker, derived Codex sandbox, short-form depends_on (#3941)
* test(#3897): failing-first coverage for §8.3 rungs 2-4

ADR-3473 §8.3 has four rungs; #3883/PR #3896 shipped the first. This pins the
other three RED before any fix.

Rung 2 — the install marker has four readers and resolveRuntime is not one.

  resolveRuntime resolves GSD_RUNTIME > config.runtime > 'claude' and reads no
  marker at all, while bin/install.js writes one (#2297) and FOUR hand-rolled
  readInstallRuntimeMarker copies exist: src/model-resolver.cts:65 (cached, with
  test seams), hooks/gsd-agent-isolation-guard.js:112, and TWICE in
  hooks/gsd-cursor-subagent-start.js at :346 and :355. Four copies of one rule.

  Fixtures and seam names mined from PR #3382 rather than re-derived; it
  implemented this rung and was closed "not on the merits".

Rung 3 — the sandbox map, and the fallback that was the real defect.

  Measured across all 35 files in agents/, deriving workspace-write iff tools:
  declares Write or Edit:

    - all 11 CODEX_AGENT_SANDBOX entries derive to their mapped value exactly,
      zero disagreements — the map carries nothing the contract does not
    - 24 roles fall through `|| 'read-only'`, of which 16 declare Write or Edit

  So the map is redundant and the silent fallback is the defect. The maintainer
  chose to derive but hold those 16 at read-only pending the question of whether
  Codex enforces sandbox_mode or merely advises; HALT.md records it.

  T20 asserts the emitted sandbox_mode PER ROLE against a captured baseline, not
  in aggregate — an aggregate passes while one role silently widens, which is
  the proxy-instead-of-identity shape this repo names. T24 and T25 fail on a
  stale hold, so the hold list cannot rot into the subset map being deleted.

Rung 4 — shortFormToId, recovered rather than invented.

  I nearly reported this as another wrong §8.3 claim: `git log -S shortFormToId`
  returns only documentation commits. That was the wrong instrument. Direct
  inspection of sdk/src/query/phase.ts at 11918dcc3^ shows five occurrences, and
  the tests match that code rather than a guess at its semantics — including
  first-write-wins on a duplicate short form.

  T43 asserts at the consumer's output: the emitted `waves` map from the real
  CLI, which pre-fix collapses to {"1":[...]} because every short-form edge is
  dropped. A unit assertion on resolveDependencyId would have passed throughout
  this defect's life.

Observed RED, this tree:
  rung 2   11/11 fail — no marker rung, no seams
  rung 3   T23,T24,T25,T26,T30 fail; T28 fails (validate agents passes a TOML
           whose sandbox_mode disagrees — it checks presence only)
  rung 4   T42,T44 fail; T43,T49 fail with waves collapsed to a single wave 1

Green and staying green: T20/T21/T22/T27 as captured baselines, #3885's
unresolvable-token warning and wave-verdict suppression, and #3785's
display-mapping passthrough. If the third tier over-reaches, those go red — that
is their job.

Disclosed weakness: T45 (a canonical id with no dash is not short-form indexed)
cannot be isolated behaviorally, because planMap always masks it. It is a
non-crash boundary pin, weaker than the other rows, and is recorded as such
rather than presented as equivalent.

* enhance(#3897): §8.3 rungs 2-4 — one marker reader, a derived sandbox, the third depends_on tier

ADR-3473 §8.3 has four rungs. #3883/PR #3896 shipped the first. These are the
other three.

Rung 2 — the install marker had four readers, and resolveRuntime was not one.

  resolveRuntime resolved GSD_RUNTIME > config.runtime > 'claude' and read no
  marker, while bin/install.js writes one (#2297) and four hand-rolled
  readInstallRuntimeMarker copies existed: src/model-resolver.cts (cached, with
  seams), hooks/gsd-agent-isolation-guard.js, and twice in
  hooks/gsd-cursor-subagent-start.js.

  model-resolver's was already the house idiom, so it was promoted rather than
  replaced: src/runtime-slash.cts now owns it, and model-resolver plus both
  hooks delegate. The hooks reach it through ensureRuntimeBuild(), the seam
  lint-hooks-runtime-build-seam enforces. No import cycle existed - checked
  both directions before moving anything.

  The marker is the THIRD rung: env > project config > marker > 'claude'.

  N1 was checked rather than assumed, and my first reading of it was wrong. A
  marker holding an unknown name comes back essentially verbatim, which looked
  like a validation gap. Measured against the env rung with the same inputs -
  including "../../etc/passwd" and "claude;rm -rf /" - the two are identical,
  because they share resolveRuntimeNameFromCandidates. N1 asks for exactly that,
  and it is met. The residual (the shared normalizer normalizes shape, it does
  not validate against the known-runtime set) is pre-existing on the env rung
  and plausibly deliberate, since a new runtime should not need a code change.
  The marker also does not widen the trust boundary in any real sense: it lives
  inside the install tree beside the code, so anyone who can write it can write
  runtime-slash.cjs itself.

Rung 3 — the map was redundant; the silent fallback was the defect.

  Measured across all 35 files in agents/, deriving workspace-write iff tools:
  declares Write or Edit: all 11 CODEX_AGENT_SANDBOX entries derive to their
  mapped value exactly, zero disagreements. The map carried nothing the contract
  did not already have, so it is DELETED rather than reconciled. What was
  actually broken is `|| 'read-only'`, which silently under-granted 24 of 35
  roles.

  16 of those 24 declare Write or Edit and would widen under derivation. Per the
  maintainer's decision (HALT.md), they are held at read-only pending the
  question of whether Codex enforces sandbox_mode or merely advises. Emitted
  TOML is therefore byte-identical for all 35 roles - asserted per role, not in
  aggregate, because an aggregate passes while one role silently widens.

  The hold list self-invalidates. A hold whose role no longer derives broader
  fails, and so does a hold naming a role with no agents/<name>.md. Without
  that it would rot into exactly the hand-maintained subset map being deleted,
  and this commit's own ledger claim would become false over time. Both cases
  were proved by injecting them and watching them throw.

  Two committed tests asserted the deleted map's existence and contents. They
  were pinning the thing being removed, so the tests moved rather than the
  production code: the 11 role-value pairs survive as a test-local
  PRE_3897_CODEX_AGENT_SANDBOX baseline, and the assertions now drive the real
  derivation against real agents/*.md. The coverage is preserved; only its
  source moved out of production code.

  validate agents gains checkCodexSandboxPosture, mirroring the existing
  checkCodexModelPosture: each installed TOML's sandbox_mode must equal the
  role's expected value, failing with role, expected and found. It previously
  checked file presence and manifest completeness only, so a TOML whose
  sandbox_mode disagreed passed.

Rung 4 — shortFormToId, recovered rather than invented.

  I nearly reported this as another wrong §8.3 claim: git log -S returns only
  documentation commits. Wrong instrument. sdk/src/query/phase.ts at 11918dcc3^
  carries five occurrences, and the implementation here matches that code rather
  than a guess at its semantics - including first-write-wins on a duplicate
  short form, deterministic from the sorted plan order.

  It resolves the bare plan number: depends_on: ["01"] now reaches
  26-01-auth-hardening. That is a control-flow change, not a diagnostic one -
  plans that silently collapsed into a single wave 1 now execute in their
  declared waves, and execute-phase.md consumes those wave values.

  In-phase only, by construction: the map is built from this phase's rawPlans,
  so a same-named short form in another phase does not resolve.

  #3785's display-mapping passthrough and #3885's unresolvable-token warning and
  wave-verdict suppression are untouched and stay green. If the third tier had
  over-reached, those are what would have caught it.

* fix(#3897): close a fail-open I introduced, and wire the posture check to its command

Two blockers from review. Both are mine, and one is a security regression my own
change created.

1. A held role could escape its hold by editing its own frontmatter.

  The Codex install loop set the sandbox identity from the agent's frontmatter
  `name:` field rather than from its filename, so the hold lookup keyed off a
  value the file itself declares:

    deriveCodexSandboxMode('gsd-doc-writer',   <real file>)          -> read-only
    deriveCodexSandboxMode('gsd-doc-writer-x', <same file, name: edited>) -> workspace-write
    deriveCodexSandboxMode('GSD-Doc-Writer',   <same file, name: recased>) -> workspace-write

  What makes this a blocker rather than a nit is the DIRECTION. The deleted
  CODEX_AGENT_SANDBOX map had the identical lookup-key quirk, but it was an
  allowlist: an unmatched key fell back to read-only, which is safe. The new
  scheme derives workspace-write from the tool contract and uses the hold as a
  subtraction, so the same mismatch fails OPEN. I converted a fail-closed quirk
  into a fail-open one and did not notice; the isolated reviewer proved it by
  execution.

  Neither safety net caught it. validateCodexSandboxHolds only checks that
  <key>.md exists, never that a file's derived identity matches its key.
  checkCodexSandboxPosture looks the canonical source up by the installed TOML's
  filename, finds nothing for a renamed agent, and treats it as a custom
  non-roster agent — silently no violation.

  The identity is now the FILENAME STEM, which is what validateCodexSandboxHolds
  already validates and what an attacker editing frontmatter cannot change
  without renaming the file — at which point the existing validator catches it.
  The lookup is case-insensitive so a recase does not slip past either. The
  frontmatter name still drives the TOML body and filename, unchanged; only the
  sandbox identity moved.

  All 35 roster files were checked: name matches filename stem everywhere, so a
  stricter "they must agree or throw" invariant would have been safe against real
  content. It is deliberately NOT added — it would abort an install on a tampered
  file where emitting a correctly-derived read-only TOML is the safer outcome.
  Recorded as a fork rather than decided silently.

2. checkCodexSandboxPosture was exported and never called.

  cmdValidateAgents (src/verify.cts) called checkAgentsInstalled and
  checkCodexModelPosture only; grep for the sandbox check in that file returned
  nothing. So criterion 3 — "validate agents fails on semantic drift, not only on
  missing files" — was unmet, and `validate agents` behaved exactly as before.
  That is ADR-3473 Decision 2's named shape: a declared policy with no executor.

  It also meant the T28 test asserted at the helper's return value while the
  COMMAND stayed broken — the ADR-3180 Decision 4(b) failure this epic exists to
  close, committed by me while enforcing it elsewhere in the same epic.

  Now wired as an additive `sandbox_posture` field beside `codex_posture`,
  following the sibling precedent exactly. Drift is report-only, not a non-zero
  exit, because that is what checkCodexModelPosture does — two sibling posture
  checks disagreeing about whether a violation is fatal would be its own defect.
  The choice is recorded in a comment rather than left implicit. A consumer-output
  test now drives the real CLI and asserts on the emitted JSON, and was shown
  failing before the wiring and passing after.

Also corrected a stale artifact: the design's Known limit L1 still claimed rung 3
was not in this deliverable, written while it was halted and false once the
maintainer unblocked it.

Verified after both fixes: the three bypass probes all return read-only, the
per-role table is 35/35 byte-identical, and both hold self-invalidation cases
still throw.

* docs(#3897): the marker rung, the derived sandbox, and the bare plan-number depends_on

Reference: the runtime precedence ladder in docs/CLI-TOOLS.md gains the install
marker rung; docs/COMMANDS.md documents validate agents' new sandbox_posture
field; docs/reference/plan-md.md documents that depends_on accepts the bare plan
number.

Explanation: a docs/features fragment keyed id 3897, so it cannot collide with a
concurrent PR hand-allocating a section number, regenerated into FEATURES.md.

ADR-3473 §8.3 gains an ANSWER blockquote in the document's own correction style,
recording what was measured and built against the section's 2026-08-26 correction
- including the qualification that checkAgentsInstalled itself still checks
presence only, and the semantic assertion lives in a sibling wired into validate
agents rather than folded into it.

No how-to. Both user-visible changes are zero-step: a non-Claude install resolving
its own runtime, and plans executing in their declared waves, both happen without
the user doing anything. docs/how-to/control-the-reported-host-runtime.md covers a
DIFFERENT ladder (resolveReportedRuntime / agent_runtime) that this change does
not touch, and was deliberately left alone rather than edited by association.

No tutorial - nothing multi-step to walk through. docs/AGENTS.md unchanged: it
documents Claude-side tools frontmatter, never Codex sandbox_mode, and the
emitted tools contract did not change.

The prompt layer documents depends_on only by example, not by schema, so nothing
there needed editing - and few-shot-examples/plan-checker.md already showed
depends_on: ['01'], which now actually resolves.

Translated copies of plan-md.md are untouched; the project treats translations as
community-maintained.

* fix(#3897): move the sandbox derivation out of the installer, off the install path, and off a third parser

The full suite came back with 26 failures across four files. Three distinct
causes, mapped individually rather than assuming the first explained the rest.

A. Requiring bin/install.js printed the GSD banner to stdout and corrupted
   `validate agents` JSON.

     Unexpected token '', "[36m   ██"... is not valid JSON

   checkCodexSandboxPosture reached deriveCodexSandboxMode by lazily requiring
   bin/install.js, whose module load prints the ASCII banner. So the command
   emitted banner bytes before its JSON and every JSON consumer broke, including
   ten tests that predate this branch. src/ reaching into bin/ was backwards
   layering that happened to also be loud.

   The derivation now lives in src/codex-agent-toml.cts - the existing Codex TOML
   domain module, no new module and no six-gate ripple - and both bin/install.js
   and src/agent-install-check.cts import it. One owner, which is §8.3's rule
   applied to the fix for §8.3.

B. The stale-hold throw fired on a legitimate partial source dir, and masked a
   security assertion.

   validateCodexSandboxHolds treated "this hold's .md is absent from the install
   SOURCE dir" as a stale hold and threw. A test fixture, or any partial install
   source, legitimately contains a couple of agents. Worse, it threw BEFORE the
   path-escape check, so a test asserting that a `../../evil` frontmatter name is
   rejected got my unrelated error instead of the traversal rejection it was
   written for. A fail-closed check of mine was hiding a real security check.

   The "no stale holds, shrink-only" invariant is a property of the repo's
   canonical agents/ roster, not of whatever directory an install happens to read.
   It is off the runtime path and enforced where it belongs, in the tests that
   already existed for it. A partial source dir now installs cleanly, and the
   evil-name case throws with its own escapes-configHome message again.

C. T8 depended on ambient process.env state.

   The marker/env parity assertion round-tripped through live process.env. It now
   compares against resolveExplicitRuntime's already-exported dependency-injection
   parameter - deterministic and hermetic, same claim. Proven still falsifiable
   rather than assumed: with the marker rung's normalization temporarily bypassed
   the two rungs diverge ("codex\n../../etc/passwd" vs "codex-../../etc/passwd")
   and the assertion fails, then passes again once reverted.

One correction folded in along the way. The first version of the move added
private _extractFrontmatterAndBody/_extractFrontmatterField helpers to
codex-agent-toml.cts - a THIRD copy of frontmatter extraction, where the graph
already shows two (bin/install.js:2348, runtime-artifact-conversion.cts:893).
Adding a third inside the epic whose thesis is one implementation per rule is not
defensible. deriveCodexSandboxMode no longer parses anything: it takes
(identity, toolsValue) and each caller supplies the tools value using the
extractor it already has. Both helpers are deleted. The identity argument is
still the filename stem, so the fail-open fix is untouched.

Verified after all three: `validate agents --raw` emits parseable JSON with no
banner and both posture fields; the four hold-bypass probes still return
read-only; the per-role table is 35/35 byte-identical at 26 read-only / 9
workspace-write; the hold list is still 16.

* fix(#3897): drop a dev-only transitive dep, make the derivation total, retire a stale fallback test

Suite down to 7 failures from 26. Three more causes, mapped individually.

A. My extractor import dragged in a script that does not exist in an installed
   tree.

     Cannot find module '../../../scripts/fix-slash-commands.cjs'

   Chain: src/agent-install-check.cts imported runtime-artifact-conversion.cjs,
   which requires command-roster.cjs, whose line 36 requires
   ../../../scripts/fix-slash-commands.cjs. That path exists in the repo and not
   in an install, so every test exercising a synthetic install dir died at module
   load. I picked that extractor for convenience without checking what it pulls
   in - the same mistake that produced the banner bug, one layer further out.

   agent-install-check now uses a single-purpose extractToolsLine on
   codex-agent-toml.cts. That is deliberately NOT a general frontmatter parser:
   we deleted those helpers a commit ago for good reason, and this reads one
   line. Verified from outside the repo root that requiring either module prints
   nothing and does not throw.

B. A test pinned the deleted name-based fallback.

   'defaults unknown agents to read-only' called generateCodexAgentToml with a
   fixture declaring tools: Read, Write, Edit. Under derivation an unknown agent
   with a writing contract correctly derives workspace-write - design row S6, a
   new writing role gets the contract, not the pin. The behavior it asserted was
   the silent fallback this rung deleted; identity no longer decides the sandbox.

   Replaced with two rows rather than a flipped string: no tools declared ->
   read-only (absence is not a grant), and Write/Edit declared -> workspace-write.
   Strictly more coverage than the row it replaces.

C. The stale-hold check still threw per derivation call.

   Last commit took the roster-existence check off the install path, but
   deriveCodexSandboxMode itself still threw when a hold's role did not derive
   broader FOR THE CONTENT IT WAS HANDED - so it fired on any synthetic fixture
   for a held role.

   The throw is gone, and it cost nothing: if a held role's content does not
   derive broader, the hold pins read-only and derivation returns read-only
   anyway, so the hold is a no-op and there is nothing to fail about. The
   staleness invariant is a property of the real agents/ roster, and
   validateCodexSandboxHolds still enforces it there - confirmed against the real
   roster after the change, not assumed.

   deriveCodexSandboxMode is now total: every (identity, toolsValue) including
   undefined and null returns read-only or workspace-write, never throws.

Verified: validate agents emits parseable JSON; the four hold-bypass probes
return read-only; the per-role table is 35/35 at 26 read-only / 9
workspace-write.

* docs(#3897): put the rung-3 decision in the shipped docs instead of pointing at an ignored path

The ADR entry and the feature fragment both ended their rung-3 explanation with
"see .gsd/phase/feat-3897-adr3473-83-rungs/45-decision-rung3-sandbox.md". That
directory is gitignored (.gitignore:55), so the rationale for holding 16 roles at
read-only was reachable only from the machine that produced it. A reader of the
ADR got a pointer to nothing.

Both now carry the reasoning inline: the criterion asks both that the sandbox
derive from the declared tool contract and that no role gain a broader sandbox,
and those cannot both hold, because a faithful derivation widens 16 roles the
deleted map never listed and that fell through its silent read-only default. The
resolution is derive-and-hold - the derivation owns the rule now, each hold is
released as its enforcement question is answered, and a hold is reversible where
a widened sandbox that turns out to be enforced is not.

Checked before assuming this was a defect class: CONTEXT.md cites
.gsd/phase/<slug>/40-design.md as its standard Design: provenance line in eight
module entries, and four other shipped docs do the same. Citing a phase artifact
is an established convention here, so those are left alone. What was wrong was
specific to these two: they put load-bearing rationale behind the pointer instead
of provenance.

docs/FEATURES.md regenerated from the fragment via scripts/gen-features.cjs
rather than hand-edited.

* fix(#3897): close a fail-open, stop a silent mis-resolution, and read a declaration as a declaration

Two orthogonal reviews on the shipped sha. Three of the findings are the same
failure class this epic exists to close, committed inside it.

1. BLOCKER - the sandbox was decided for one identity and applied to another.

   bin/install.js derived sandbox_mode for the filename stem and then wrote the
   result to `${name}.toml`, where name comes from the file's own frontmatter.
   Make the two disagree and a HELD role's artifact goes wide:

     rename gsd-doc-writer.md -> gsd-doc-writer-v2.md, keep name: gsd-doc-writer
       -> stem is unheld, derives workspace-write, lands on gsd-doc-writer.toml
     add any gsd-*.md whose frontmatter name: is a held role
       -> clobbers that role's toml with workspace-write

   Both emit read-only on origin/next, because the deleted map was an allowlist
   and a miss fell back safe. This is a regression my change introduced. The
   previous review round moved the HOLD KEY off frontmatter to the filename stem
   and left the OUTPUT PATH on frontmatter; my own comment at install.js:6985
   calls that value attacker-editable, four lines above the line that uses it as
   the filename.

   The decision is now made over BOTH candidate identities, most-restrictive
   wins: if either the stem or the emitted name is held, the mode is read-only.

2. MAJOR - hold matching was toLowerCase() only, so confusables escaped.

   Turkish dotted/dotless i, fullwidth, NFD, trailing space/NBSP/dot/newline,
   ./ and ../agents/ all slipped the hold and emitted workspace-write.
   Identities are now basenamed, trimmed of NBSP/zero-width/control characters,
   NFKC-normalized and lowercased - and anything still carrying a character
   outside [a-z0-9._-] is treated as suspicious and derives read-only. We do not
   enumerate confusables; every shipped roster file is ASCII, so refusing to
   widen on an identity we cannot recognize is fail-closed with no false
   positives on real content.

3. MAJOR - the short-form depends_on tier mis-resolved SILENTLY.

   shortFormToId keyed on the last dash-segment of any canonical id with no
   constraint that it is a plan number, so a phase holding 09-FIX-auth-PLAN.md
   made depends_on: ["auth"] bind at wave 2 with zero warnings. This is the
   worst shape in the epic: the unresolvable-token warning fires on a DROPPED
   token, so a MIS-RESOLVED one is invisible and the tool reports a confident
   wave assignment built from a wrong edge. A wrong edge is worse than a missing
   one.

   The segment must now match /^\d+$/, which is exactly the contract
   docs/reference/plan-md.md already documents. This tier was recovered verbatim
   from the retired SDK lineage, which carried the same defect; we are
   deliberately NOT preserving it bug-for-bug, and the comment says so, so the
   next reader does not "restore" it.

4. MAJOR - the derivation was reading a declaration as an absence.

   extractToolsLine read one line, so a YAML list-form tools: block returned only
   its first item. Two roster files use list form, and gsd-nyquist-auditor
   declares Write and Edit there - parsed as "- Read", found no write tool, and
   emitted read-only. Rung 3's headline claim is that sandbox_mode derives from
   the declared tool contract; that claim was false for 2 of 35 roles and
   materially wrong for 1. Reading a declaration as an absence is the silent-drop
   class this epic exists to close.

   Renamed extractToolsValue and taught it both shapes. gsd-nyquist-auditor now
   derives workspace-write and joins CODEX_SANDBOX_HOLDS as its 17th entry, per
   the standing derive-and-hold decision - so emitted TOML stays byte-identical
   at 26 read-only / 9 workspace-write while the hold list finally records every
   role that would widen. A previous pass declined this fix because it moved the
   count; that inverts the priority. Byte-identity is preserved THROUGH the hold,
   not by leaving a parser broken.

   Divergence check, because this is where that bug hides: both paths feeding
   sandbox derivation - install.js's emitter and checkCodexSandboxPosture - now
   route through the one extractor. The tools readers in
   runtime-artifact-conversion and install.js's other frontmatter call sites
   serve Claude-side emission and do not feed sandbox derivation.

Also fixed, each real: the posture check's `found` used a naive whole-file regex
where its own sibling uses the block-aware scanner, so prose inside
developer_instructions produced a false violation; `found` skipped
truncatePostureValue and leaked a 300-char value into validate agents output;
deriveCodexSandboxMode's absolute never-throws claim was false for an object with
a throwing toString; T49 could not falsify cross-phase leakage (its target phase
had its own 01, so a globally-scoped map passed too); T20/N6 iterated a hardcoded
table and pinned the FIXTURE size, so a 36th agent would be silently unchecked;
three tests reimplemented the code they were testing instead of importing it; and
T2-T4 deleted GSD_RUNTIME without restoring it.

Verified: hold list 17, gsd-nyquist-auditor derives workspace-write unheld and
emits read-only held, roster 35/35 at 26/9, depends_on ["auth"] no longer
resolves while ["01"] still does, both identity-bypass cases and every confusable
vector emit read-only.

* docs(#3897): the hold list is 17, and the reason the 17th was missing

The count read 16 because the derivation could not read the declaration it
claimed to derive from: the tools reader was single-line, so a YAML list-form
tools: block returned only its first item and gsd-nyquist-auditor's declared
Write and Edit were read as an absence.

Both the ADR entry and the feature fragment now carry the corrected count and the
reason for it, rather than a silently updated number. Deriving from a declaration
you cannot parse is not deriving, and a flattering count is worse than a wrong
one because it looks settled.

34399eed70 docs(#3942): ADR — the emitted-drift ack belongs in a commit trailer (#3943)
The acknowledgment explains one PR's unattributable emitted-artifact delta.
The moment that PR merges the delta is in the base, so the acknowledgment can
never clear anything again — its useful life is exactly the PR's open window.
It is stored in permanent, shared, merge-path state. That single lifetime
mismatch is the origin of six consecutive rounds of defect-and-fix (#2789,
#2914, #3078, #3823, #3842, #3875), each fix generating the next defect, ending
in a scheduled sweeper whose own PR (#3927) could not merge itself.

ADR-3942 supersedes ADR-2719 section 3 only, and its #2789 Amendment. Sections
1, 2 and 4-7 are retained and depended upon: the conservation law itself is not
in question, only where its escape hatch is stored.

Also lands the root-cause research note behind the decision, and regenerates
the ADR index.

Two corrections to earlier framing, recorded here rather than dropped:

- Per-commit trailers do NOT reliably survive squash-merge; the repo's own
  ship.md:306 reconstructs a gate trail precisely because squash discards it.
  The ADR therefore claims no durable audit record on next. Non-survival is the
  property being bought, not a cost.
- The test job checks out at depth 1 (test.yml:107-110, no fetch-depth key). A
  depth-1 checkout cannot see the PR's commit range and fails VACUOUSLY rather
  than erroring, so fetch-depth: 0 is a named decision in the ADR and the
  acceptance criterion requires a test that fails under depth 1.

Docs-only; no code, no changeset.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

e35ac2a2c. Also records the scope caveat that the CLI write path rebuilds the
frontmatter block independently, so the marker binds at the transform layer.

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

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

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

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

ADR-3473 §8.1 review findings, addressed inline:

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

Refs #3881

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

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

Root cause was two clobber sites, not one:

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

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

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

Refs #3881

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

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

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

* chore(#3881): backfill changeset PR number

* 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.

* 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).

scripts/mutation-matrix.cjs COVERED entries and tests/mutation-matrix-ratchet.test.cjs
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
extractFrontmatter), and the null-byte sentinel round-trip surviving at region
offset 1. Did not lower minScore.

The CLI end-to-end rows in tests/mutation-score-ratchet.test.cjs hardcoded config-schema's real floor (52), which commit 973321541 legitimately ratcheted to 74 -- breaking a test pinned to the exact value the mechanism under test exists to change. 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.

A tracked-document sweep of 910 *.md files cannot see this dependent: repairAmbiguousColonValues's one real caller is user hand-edited STATE.md content that never lives in this repo's tree, only on end users' machines, and is pinned by tests/smart-entry.unit.test.cjs. 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.

* docs(#3889): ADR-3889 — the process-exit contract

Records the decision for epic #3889: one Outcome vocabulary, one pure
projection to an integer, two terminators sharing both.

Doc-only. Regenerates docs/adr/README.md via gen-adr-index.

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

* docs(#3889): rewrite ADR-3889 as an exit-code registry, on measured evidence

The first draft's census was grep-derived and roughly 2x inflated: it counted
comment prose and also matched process.exitCode, the correct pattern. An AST
census (@typescript-eslint/parser, CallExpression on process.exit) gives 128
deduped call sites, 71% of them in hooks/, against 88 process.exitCode
assignments already in use. scripts/ is effectively migrated (39:1).

Corrects the framing accordingly: the seam (src/cli-exit.cts) already exists
and is already adopted; what is missing is an allocator and a hooks adapter.

Replaces the fixed six-value enum with a registry: 0 and 1 free, 2 reserved to
the Claude Code hook protocol, 3-13 forbidden (Node reserves them), 64+
allocated with one meaning and one owner per code. Domain codes permitted.

Adds three findings obtained by reading and executing the code:
- ui-safety-gate/api-coverage report empty stdin as an authoritative negative
  verdict (exit 1) — reproduced with a control
- four modules hand-roll the same three-outcome convention, documented only in
  a comment at src/ui-safety-gate.cts:137
- two capability fragments fabricate {"detected":false} on probe failure, while
  the honest {"skipped":true,"reason":"sdk-failed"} form already exists in-tree

389bc86e02 enhance(#3883): route every slug call site through its canonical owner (#3896)
* docs(#3883): correct section 8.3 against the tree

I wrote this section in Phase 0 stating rules I had not executed against the
tree. Measured at 832dcbb75, three statements are wrong.

The slug count is 11 across 5 files, not 13; two of the thirteen were an
unrelated tokenizer regex. The divergence is real and reproduced.

resolveRuntime reads no install marker at all and has no cache; PR #3382,
cited as prior art for that rung, is closed unmerged.

The Codex sandbox is still a hand-maintained subset map with a silent
read-only fallback, and validate agents checks file presence only -- both
halves of that claim are false.

The shortFormToId rule is accurate. The guard roster names no casualty for
this rule.

Section 8.3 is therefore a work list, not a conformance check.

Declared different: gsd2-import.cts:97 (no truncation), active-workstream-store.cts:97 (fixed ASCII env-key domain, already matches).

PR #3896's Stryker (core-utils) shard was cancelled at the 15-minute
shard cap. Stryker's command-runner bills one `node --test <file>`
invocation as a single unit costing whatever the file's slowest run
costs, re-run once per mutant (documented in
tests/state-contract.test.cjs's header, #2790 precedent). A3/A5 drove
every CLI-reachable slug site through runGsdTools (a real child-process
spawn per call, ~85-170ms each across ~70 calls), accounting for ~7.1s
of the file's ~7.9s wall time.

commands.cts:cmdGenerateSlug and init.cts:cmdInitExecutePhase/
cmdInitPhaseOp/cmdInitProgress are plain functions reachable in-process
from the built gsd-core/bin/lib/*.cjs, so this calls them directly
instead of spawning gsd-tools, capturing their fd-1 JSON output with the
bug #1008 fs.writeSync-mock pattern already used in tests/io.test.cjs
and tests/init.test.cjs. A hermetic-env helper reproduces the isolation
runGsdTools's { HOME: tmpDir } + testEnvBase() gave the child process.

File wall time drops from ~7.97s to ~1.1s (246/246 passing, same
coverage), well inside the 15-minute cap even at hundreds of mutants.

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

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

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

Refs #3871

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

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

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

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

Refs #3871

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

Review of the first two commits found four things.

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

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

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

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

Refs #3871

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

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

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

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

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

Refs #3871

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

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

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

§8.1–§8.5 state the epic's B1–B5 criteria as contract rules with no phase
assigned yet. §8.6–§8.8 assign Phases 1–3 to the STATE.md family that

by hand into nine artifacts.

Derivation authority is explicitly NOT in scope here — it lands as

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.

8526bd46f8 enhance(#2475): scope ADR-443 item 1 to the operator surface and ratify the ADR (#3688)
* test(#2475): widen the item-1 effort-caller guard to both CLI argument shapes

The guard matched only `resolve-execution ... --effort\s`, but the CLI also
accepts `--effort=<level>` (gsd-core/bin/gsd-tools.cjs). A workflow written
with the equals form was a live invocation-override caller the guard passed
silently, along with `--effort` at end-of-input.

Lift the matcher to a shared predicate and assert it directly against every
shape the CLI accepts, plus the decoys it must not fire on (--effortless, a
bare --effort with no resolve-execution, item 6's --attempt caller, a call and
flag split across lines).

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

* docs(#2475): scope ADR-443 item 1 to the operator surface and ratify the ADR

ADR-443 sat at Proposed on one condition: its Decision item 1 orchestrator
invocation override needed a caller in shipped orchestration. Per the
maintainer's ruling, take unblock path (b) for item 1 only -- record that the
override is an operator-facing CLI surface, deliberately not driven by shipped
orchestration, and ratify.

The ADR's own path (b) wording is not adopted verbatim: it says the scope is
limited to static install-time propagation, which is false on both counts --
item 6 has a live caller (#2296) and #2481 delivered a live invocation-time
argv channel. Only one precedence step is narrowed.

No consumer was invented to clear the gate: nobody has asked for a per-run
effort override, and #2475's actual complaint is already closed by the
cascade-to-argv path. The amendment states explicitly that --effort remains
supported and is not deprecated, so the scoping is not read as dead code.

* docs(#2475): correct two bare-`gsd` invocation examples to `gsd_run`

There is no `gsd` binary -- package.json exposes gsd-core, gsd-tools, gsd_run
and gsd-mcp-server. Both sites presented a command that cannot run as written.

One is in this branch's own new ADR-443 amendment; the other is a pre-existing
error in the docs/CONFIGURATION.md assumption_delta row, fixed here rather than
deferred. No translated copy carries either line, so no i18n drift is created.

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

* test(#2475): record the guard/CLI divergence risk on the item-1 matcher

The predicate independently models gsd-tools.cjs's argument parser rather than
sharing a constant with it, so a third --effort spelling would leave the guard
reporting green while ADR-443's ratifying invariant silently stopped holding.
Name that risk where the next editor will meet it.

Also restores the bounded-prose rationale that was attached to the eslint
directive removed in 39793079c -- the directive went unused once the regex moved
to a const, but the reasoning it carried is still worth having.

9e4f0e99ad fix(#3631): exclude only __pycache__-resident bytecode from the consent digest (#3650)
* test(3631): failing-first coverage for bytecode-cache in the consent hash

bundleContentHash digests a walk with no exclusion, so a routine 'python3 -m unittest'
inside a Python-backed capability bundle writes __pycache__ under the bundle, the
recomputed hash stops matching the consent record, and the capability silently goes
inactive — no error, no warning, and loop render-hooks then omits its step and gate.

Two distinct triggers, and the second is the sharper one: collectBundleEntries pushes a
{kind:'dir'} entry for EVERY directory and the digest emits a TAG_DIR marker for it, so an
EMPTY __pycache__/ flips the hash before a single .pyc is written. A fix filtering only
*.pyc would leave that live. Verified by execution against the built lib: 5 of 7 probe
rows diverge from intent today, including the empty-directory row.

The anti-regression rows are the point of the shape: editing a real scripts/m.py and
adding node_modules/pkg/index.js must BOTH still change the hash. node_modules is
deliberately not excludable — its contents are required at runtime, so dropping it from
the digest would stop consent binding executable content. The symlink row pins ordering:
exclusion must apply after the lstat fail-closed rejection, never before.

Refs #3631

* fix(3631): exclude derived bytecode caches from the consent digest

RED proven at e5ba8f1fe on the remote runner: 8 failures, exactly the rows predicted to
fail, with the four anti-regression rows already green.

collectBundleEntries now skips a hardcoded, gitignore-independent set from the DIGEST:
basenames __pycache__, .pytest_cache, .DS_Store, and any .pyc/.pyo file. Matching is
byte-exact on the raw Buffer name (the walk never utf8-decodes) and case-sensitive, so the
digest does not vary with how a name happens to be spelled on a case-insensitive volume.

Three properties were preserved deliberately, each pinned by a test:

  - The filter runs AFTER the lstat symlink/non-regular fail-closed rejection. Filtering
    first would have turned the exclusion into a way to smuggle a symlink past the check;
    a symlink named x.pyc still throws.
  - Excluded entries still count toward BUNDLE_MAX_FILES and BUNDLE_MAX_TOTAL_BYTES. The
    caps guard the WALK; the digest answers a different question, and exclusion must not
    become an unbounded-bytes hole.
  - An excluded DIRECTORY is neither emitted as a TAG_DIR marker nor recursed into. The
    directory marker was the sharper half of this bug: an empty __pycache__ flipped the
    hash before any .pyc existed, so a *.pyc-only filter would have left it live.

The issue proposed either a gitignore-aware walk or a list including node_modules. Both
are rejected. A consent binding must not delegate its scope to a .gitignore the bundle
author does not control — one line there would drop arbitrary executable content out of
the hash. And node_modules holds code that is required at runtime; excluding it would stop
consent binding executable content, turning a usability bug into a supply-chain hole. What
makes __pycache__ different is that CPython validates each .pyc against its sibling
source, which remains hashed, so a real code change still invalidates consent.

Docs: CONTEXT.md's 'EVERY regular file AND directory' claim is corrected in place.
ADR-2363's residual-gap section said the walk had 'no exclusions' — per
docs/adr/README.md ('ADRs are append-only') that is corrected by a dated amendment rather
than an in-place edit. Its D4 argument is unaffected: skill bodies are .md and stay bound.

Fixes #3631

* fix(3631): narrow the digest exclusion after two isolated security reviews

The first cut of this fix passed the full suite and was still wrong. Both orthogonal
reviews rejected it, and the second one found a hole that has nothing to do with Python.

HIGH — an excluded DIRECTORY was 'continue'd before recursion, so its whole subtree was
permanently outside the digest. Declared hook script paths allow '_', '.' and '/' with no
directory or extension rule, so hooks:[{script:'__pycache__/run.js'}] installed, executed
via node, and its bytes could be rewritten forever without moving the hash. Ship benign
v1, collect consent, then own the machine. No Python involved.

FALSE RATIONALE — the justification I wrote into the code, CONTEXT.md, the ADR amendment
and the changeset claimed CPython validates a cached .pyc against its sibling source, so
the source staying hashed kept consent honest. That is not true, and I proved it by
execution rather than argument: default timestamp invalidation compares only the source's
mtime and size, both settable by anyone who can write the bundle. A forged pyc ran while
the .py was byte-identical.

Also wrong: '*.pyc' matched anywhere, but a legacy sourceless scripts/x.pyc IS importable,
so excluding it was a live vector.

Narrowed to what is actually defensible:
  - a DIRECTORY named __pycache__/.pytest_cache has only its TAG_DIR marker suppressed;
    the walk still recurses and hashes every non-excluded child.
  - .pyc/.pyo are excluded ONLY when the parent basename is exactly __pycache__.
  - a regular FILE named __pycache__, and a DIRECTORY named x.pyc, stay bound.
  - declared hook paths containing a __pycache__/.pytest_cache segment or a .pyc/.pyo
    basename are now rejected in both validator copies — a file named .pyc can contain
    perfectly valid JavaScript, so the exclusion must not be reachable from a declared
    surface.

Accepted residual risk, stated plainly in ADR-2363 and CONTEXT.md instead of explained
away: a forged __pycache__/mod.pyc matching an unmodified, still-hashed mod.py executes
without moving the digest. Before this change that write was detected. It is accepted to
stop routine bytecode caching from silently deactivating capabilities, and it is bounded —
the attacker needs post-consent write access, everything outside __pycache__/*.pyc stays
hashed, and no declared surface can point into the excluded space.

Known limitation, not papered over: .pytest_cache CONTENTS still move the digest. Only the
directory marker is suppressed. Excluding that subtree would reopen the HIGH finding.

Refs #3631

* fix(3631): drop the .DS_Store exclusion and pin what the caps actually bind

Second round of isolated review findings. The hardening closed the two original holes —
both re-reviews confirmed that by execution — but it introduced a new one of the same
shape, and left three claims unbacked.

HIGH, self-inflicted: .DS_Store was excluded from the digest at any depth, but the hook
path validator was hardened only for __pycache__/.pytest_cache/.pyc/.pyo. So
script:'hooks/.DS_Store' was ACCEPTED, runnableHookCommand emits the bare quoted path for
a non-.js name (the branch .sh hooks already use), and capability-source copies it with
its mode bit intact. Ship it +x with a benign shebang, take consent, then rewrite it
forever — the digest never moves. Fixed by DELETING the .DS_Store exclusion rather than
teaching the validator about it: .DS_Store has nothing to do with this issue's Python
bytecode symptom, and an excluded filename is a permanently unhashed name. The narrower
the exclusion, the smaller the hole.

The residual-risk bound in ADR-2363 and CONTEXT.md claimed declared surfaces cannot reach
excluded space. That is false and is now stated correctly: node resolves an unregistered
extension through the default .js handler, so a hashed, consent-covered hooks/run.js that
requires '../__pycache__/mod.pyc' reaches it in one hop. The validator guard raises the
bar for DECLARED surfaces; it does not contain the risk. The two bounds that are real —
post-consent write access required, everything outside __pycache__/*.pyc still hashed —
are kept.

The BUNDLE_MAX_FILES boundary test had gone vacuous: it padded with root-level *.pyc,
which the hardening made non-excluded, so it no longer proved anything about excluded
entries while the ADR claimed the caps were test-pinned. It now pads __pycache__/f{i}.pyc,
with the arithmetic re-derived by execution (capability.json + the still-counted
__pycache__ dir + N). BUNDLE_MAX_TOTAL_BYTES had zero coverage at all and is now pinned by
a sparse 32 MiB __pycache__/big.pyc that must still trip the size cap — the test that
proves exclusion did not become an unbounded-bytes hole.

Added the parity assertion CLAUDE.md's Generative Fix Divergence rule requires for the two
isSafeHookScriptPath copies, and proved it can fail: mutating one BUILT copy to drop .pyo
made the parity check report the divergence. Also pinned semantics that were correct but
untested and would have survived mutation — __pycache__/sub/x.pyc stays hashed (the parent
resets to sub, which is the recursion threading itself), .pytest_cache/y.pyc stays hashed,
and .pyo in both directions, which was a free surviving mutant.

Changeset rewritten: it still described the rejected wholesale-exclusion semantics.

2972da4c9d enhance(#3619): ratchet the platform seam with local/no-private-binary-resolution (epic #3411 Phase 3) (#3636)
* chore(#3619): ratchet the platform seam with local/no-private-binary-resolution

Epic #3411 Phase 3, the ratchet. Scope revised with maintainer approval and
recorded on the issue: the epic's literal ask was a rule rejecting a bare-name
spawn outside the seam. Surveyed at ac1b6d679, ~30 such sites exist and none is
a defect — git, gh and npm ship native .exe that CreateProcess resolves unaided,
and the rest are POSIX-only tools. ADR-1703 rules 2 and 3 forbid grandfathering
and escape hatches, so a literal rule would be unsuppressable and would force
rewriting 30 correct calls.

The epic's actual thesis was four private RESOLVERS, not four bare spawns. So
the rule flags re-implementing resolution: reading PATHEXT in any casing from
any object, and a hardcoded list carrying two or more of .exe/.cmd/.bat/.com —
precisely the shapes fallow-runner's candidateNames and gsd-tools' PATHEXT
string had before Phases 1 and 2 deleted them.

Three boundaries were arrived at rather than assumed:

  two-or-more   a single .endsWith('.cmd') is a classification, not a candidate
                set; runtime-hooks-surface derives .cmd shim paths that way
  boundary-aware  a naive substring test flags .execute and .compacting, caught
                on src/host-integration.cts before it could become a false
                positive nobody could suppress
  suffix-anchored  the seam exemption matches src/shell-command-projection.cts
                exactly; a substring match would also exempt the dispatch test
                file. Case I9 pins it.

PATH scans are deliberately NOT flagged — membership checks (bin/install.js)
are indistinguishable from resolution scans, and an unsound rule in a
zero-escape-hatch architecture is worse than no rule.

To make the ratchet strict with no carve-out, resolveExecutableBinary gained
pathOverride: search THIS PATH, read everything else including PATHEXT from the
ambient environment. resolveFallowBinary now supplies its own search path
without hand-threading PATHEXT, which would itself have been a private read.
The three alternatives were all worse: exempting the file is grandfathering,
exempting the AST shape is a carve-out every future caller must replicate, and
dropping the pass-through would silently ignore a user's real PATHEXT — buying
a lint rule with a correctness regression.

eslint-rules/** is outside the rule's globs rather than exempted, because
portability-vocab.cjs owns the extension set. scripts/**/*.cjs got its own block
so that exclusion does not leave a hole in the ratchet.

Started green with nothing suppressed. Proven able to fail: a fixture with both
signals reports two errors.

* fix(#3619): close the PATHEXT destructuring evasion and correct two overclaims

Adversarial review found a trivial evasion of the rule's primary signal: the
visitor only handled MemberExpression, so

  const { PATHEXT } = process.env
  const { PATHEXT: exts } = process.env
  const { Pathext } = opts.env

were all unflagged. That is a common idiom, not an exotic bypass. An ObjectPattern
visitor now catches it in every form — renamed, any casing, any receiver, string
keys — while leaving a computed key alone, since it is not statically decidable.
I10-I13 pin the invalid forms and V9/V10 pin PATH and the computed key.

Two overclaims corrected, both mine:

Standards review proved the docs were factually wrong. Both the ADR amendment and
the CONTEXT.md entry asserted that tests/shell-command-projection-dispatch.test.cjs
is still linted by this rule. It is not — the rule's surface is src, gsd-core/bin,
scripts and hooks, and tests/** is deliberately outside it because test setup
legitimately assigns process.env.PATHEXT (fallow-runner's P3 does exactly that).
The suffix-vs-substring distinction is therefore proven by RuleTester case I9
feeding a synthetic filename, NOT by real coverage of that file. Both documents now
say so.

The rule's own docstring claimed the seam exemption matches the seam path
'exactly'. It is a suffix match, so a nested foo/src/shell-command-projection.cts
would also be exempt. Suffix matching is kept — it is how sibling rules resolve
paths and the nested case does not exist — but the docstring now states the
boundary rather than overstating the precision.

The evasion fix was verified by executing eslint against both destructuring forms
in scripts/, not by inspection. Probe: 31/31.

924f649f87 docs(#3625): record the spawn-library evaluation as ADR-3625 (#3632)
Spike outcome for #3625: evaluate cross-spawn / nano-spawn / execa against
the hand-rolled Windows binary resolution and cmd.exe mediation that epic
#3411 Phase 1 (PR #3621) is landing in the platform seam.

Verdict: stay hand-rolled, with revisit-if conditions recorded so the call
is not re-litigated in a future PR.

Evidence, per the issue's "Done when" list:

- Sync/async verdict per candidate. nano-spawn is async-only — settled by
  its own README, which lists "synchronous execution" among the features
  execa has and it does not. cross-spawn exposes `.sync`. execa exposes
  execaSync, which its own docs discourage.
- CVE-2024-27980 escaping verdict per candidate. None uses shell:true.
  cross-spawn independently arrives at the SAME mechanism the seam uses:
  cmd.exe /d /s /c with a pre-escaped line and windowsVerbatimArguments.
  That validates the seam's approach rather than superseding it.
- Maturity axes scored with measured data (registry metadata 2026-08-18,
  transitive footprint measured by install).

Two premises in the issue did not survive measurement, both recorded:

- The CRITICAL 167-symbol/53-file blast radius is a `direction:both`
  measurement, inflated by downstream callees. A call-shape change ripples
  to CALLERS: upstream at depth 15 is 14 symbols / 7 files, MEDIUM, and it
  terminates at depth 4. The decision does not rest on the CRITICAL figure.
- The cited vendoring precedent path does not exist; the real one is
  gsd-core/bin/lib/vendor/re2js.cjs.

Decisive against the only structurally-eligible candidate (cross-spawn):
it resolves process.cwd() first on Windows even when an explicit PATH is
supplied, calls process.chdir() during resolution, and keys escape depth on
a node_modules/.bin/*.cmd path regex of the same shape #3411 was filed to
delete. Adoption would also break execTool's observable not-found contract
across 53 dependent files.

Doc-only: docs/adr/** plus a root-level CONTEXT.md pointer. The CONTEXT.md
addition is a new line rather than an edit to the seam's glossary paragraph,
which PR #3621 rewrites wholesale — same-line edits would conflict on merge.
ADR index regenerated via scripts/gen-adr-index.cjs --write.

lint:ci exit 0; lint-docs-required and changeset/lint both run with
GITHUB_BASE_REF=next and report ok_no_user_facing_changes.

Closes #3625

cc3fd4548d docs(#2866): reconcile ADR-3574 against the shipped environment (#3622)
The ADR was written mid-epic and describes a tree that no longer exists.

There are now two choreographies, not three: phase 6 deleted bin/install.js's
agent-staging loop and its _DESCRIPTOR_AGENTS_RUNTIMES gate outright, so the
refusal in decision 1 governs a two-way divergence.

The ADR's own revisit condition has been met. It said to reopen the
unification question when the applySurface descriptor-agents migration
completed. It has. Revisited on evidence: the shapes did not converge on the
axis that mattered, because phases 6 and 7 touched agents and exports, not the
prune. applySurface still prunes by allow-list so it cannot delete a user file
by construction; installRuntimeArtifacts still wipes and restores a snapshot.
Decision 1 stands, for a narrower and better reason than when it was written.

Records delivery status per decision, including that decision 3 was already
satisfied when measured and decision 4 was the hardest part rather than the
independent one the ADR predicted.

Notes that #2875's AC1 is now doubly stale - deliberately unmet, and naming
three call sites where two remain - so anyone reconciling the tracker treats
this ADR as governing rather than the criterion as outstanding.

682eaae3f0 enh(#2876): retire the dead and pass-through exports from bin/install.js (#3615)
* enh(#2876): retire the dead and pass-through exports from bin/install.js

The installer exported 197 names and had zero production consumers - every
non-test require of it repo-wide sits inside a comment. Its interface was
shaped by test access, not by callers.

Removes 9 dead exports and 61 pass-throughs, repointing their tests onto the
extracted modules' own interfaces. 197 down to 127.

Every count in the issue was wrong: 197 exports not 188, 9 dead not 12, 61
pass-throughs not 49, 44 test files not 42 - and the audit itself then missed
7 more consumer files. restoreUserArtifacts was on the dead list but ceased to
exist in phase 6, and two _GSD_EFFORT_MANIFEST_* names listed as dead are now
genuinely asserted, so acting on that list would have deleted live exports.

7 of the 9 dead names collide with an independent declaration that install.js
delegates TO. Each removal was justified by which declaration a reference
resolves to, never by whether the name appears somewhere.

Coverage parity was the gate rather than test greenness: per-file counts were
captured before any edit and diffed after. 44 of 45 files are byte-identical;
the single delta is one added assertion, not a loss.

The sweep for scattered require sites found two forms static grep misses -
require(VARIABLE) and multi-line require() - plus tests asserting that
install.js re-exports the SAME object, which now assert retirement instead.

* fix(#2876): close review findings — restore the duplicate-body guard, sweep orphaned code

Both review engines found real defects in the first cut.

The DEFECT.GENERATIVE-FIX single-owner guard from #1511 had been repointed
from a reference-identity check to install.X === undefined. Those are not
equivalent: the guard exists to catch a duplicate function body reintroduced
into install.js, and the replacement passes cleanly if that duplicate is used
internally and never exported. It now walks bin/install.js's real top-level
bindings, so it catches a duplicate under either shape, exported or not -
strictly stronger than the check it replaced. Proved by injecting a duplicate
and watching it go red.

That weakening survived the coverage-parity gate because the assertion count
never moved. The gate compares counts, so an assertion that changes meaning
rather than number is invisible to it.

Removing the exports had orphaned their wrapper bodies: 14 dead wrappers, 9
consts and 9 destructure entries, several pre-existing and found by the same
sweep. Dead code left in the file this phase exists to shrink.

Three more comments claimed re-exports this phase removed, and tests were
reading Cursor and Windsurf hook constants from install.js's local copy while
calling functions from the hooks surface - equal today, with nothing holding
them equal. The local consts now reference the owning module.

3ab0007164 enh(#2875): materialization primitives — durable user-artifact staging and descriptor-authoritative agents (#3600)
* fix(#2875): stage user artifacts durably across install wipes (#1874-F19)

preserveUserArtifacts held user files only in an in-memory Map across the
wipe, so any process death between preserve and restore lost them outright.

Seven call sites, not the four the issue records. Three of them never called
the helper at all - they open-coded the same read/wipe/write - so searching
for callers under-counted by construction; the extra sites were found by
sweeping for the pattern instead.

The worst is the mainline install path, where the crash window spans the
entire gsd-core tree copy rather than a single rmSync.

Adds src/user-artifact-staging.cts: durable on-disk staging with a record
written after the copies land as the commit point, plus recovery of orphaned
batches on the next run - without recovery the staged bytes survive but the
user's file is still gone, which would pass its own test while delivering
nothing.

Routes copyPreservingSymlink through installFs() so staging cannot bypass the
install fs seam, and reunites its symlink-safety docblock with the function it
documents.

* docs(#2875): amend ADR-3574 with four claims disproved by implementation

Implementing Phase 6 disproved four statements the ADR rests on. The central
decision - no single materializer - is unaffected and stands.

Corrected: decision 3 was already satisfied, so nothing was extracted; the
agents-bypass runtime set omitted claude, kilo and opencode, and closing it
needed three new pieces of descriptor contract rather than proceeding on its
own terms; three of the four blockers the layout comment names were already
stale; and F19 is seven call sites, not four.

Records the generalizable lesson: the defect is the pattern of holding user
data in memory across a wipe, not the helper, so searching for callers of the
helper under-counts by construction.

Also resolves the ADR's open question on USER_OWNED_ARTIFACTS membership, and
notes that copyPreservingSymlink needed routing through the install fs seam
before it could be reused.

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

* fix(#2875): close dangling-symlink blind spot and harden staging recovery

An adversarial review found the F19 staging work shipped red and unsafe.

Root cause, shared by two arbitrary-write findings: hasExistingSymlinkBetween
missed dangling symlinks in both its root check and its per-segment walk,
because it probed with existsSync, which is false for a link whose target does
not exist. Fixing only the new module would have reused a guard that was
itself blind. This guard protects the whole install tree.

Recovery no longer throws: it degrades per entry and per file, so one bad
batch cannot block the others. Previously an unrecoverable entry propagated
out of the first statement of install and uninstall, before the cleanup that
would have removed it - wedging the installer permanently.

Partial fs adapters now throw on any omitted method instead of silently
reaching the real filesystem, closing the trap that let a test poison list
pass while real IO happened.

Staged names must be flat, recovery refuses a dangling destination symlink,
and a batch whose recovery genuinely failed is no longer swept - it was
discarding the only durable copy of the file it had just failed to restore.

Replaces three tests that could not fail, including the one labelled negative
proof.

Known limitation, documented not closed: concurrent installs sharing a staging
key can still lose a batch. A real fix needs a cross-process lock.

* enh(#2875): make the descriptor authoritative for the agents kind

Deletes the inline agent-staging loop in bin/install.js and the
_DESCRIPTOR_AGENTS_RUNTIMES set, so every runtime materializes agents from
its capability descriptor instead of an inline hostBehaviors dispatch.

Closing it needed three pieces of contract the descriptor pipeline never had,
all reducible to one missing input - per-agent resolution context: a
frontmatter-extensions step for claude's effort and disallowedTools, per-agent
model-override resolution for kilo and opencode, and a named branding
converter for hermes, whose rewrite data was already declared.

Seven runtimes were on the loop, not the six the design recorded - kimi-code
was found by a golden fixture, not by analysis. claude-local and kimi-code
both silently lost their agents mid-change; the fixtures caught both and the
cause was fixed rather than the fixtures regenerated.

A parity harness gates the migration: both pipelines over identical inputs,
byte-identical output including filenames, per runtime. It is demonstrated
red before being trusted. Surface and install paths converge for all seven,
which also fixes surface previously writing no agents for these runtimes.

Codex's config.toml strip stays put - it mutates host config, which no
descriptor kind models.

Also routes install-model-override-resolver and install-effort-resolver
through the install fs seam. Both leaked real filesystem IO from the install
call tree; the stricter adapter is what exposed them.

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

* docs(#2875): record the agents-descriptor migration and correct the ADR count

The _DESCRIPTOR_AGENTS_RUNTIMES allow-list no longer exists, so the host
integration guide told readers to join a set that is gone. Replaces that with
what is now true - declare an agents entry and it installs, on the surface
path as well as install - and points anyone needing a per-agent transform at
the three extension points rather than at a new inline branch.

Corrects the ADR amendment: seven runtimes were on the inline loop, not six.
kimi-code was found by a golden fixture going red, not by reading. That is the
third short count this phase, all from enumerating by symbol or set membership
when the thing that matters is a behavior.

Adds the Changed changeset for the surface-path convergence.

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

* docs(#2875): amend ADR-2866 - claude global always wrote agents on disk

The claude row's global=[skills] described what capability.json declared, not
what the installer wrote. bin/install.js's inline agent-staging loop was never
scope-gated and never consulted the descriptor, so a claude --global install
has always written agents/gsd-*.md.

Phase 6 closes the gap by deleting that loop and declaring agents on claude's
descriptor at global scope. On-disk bytes are unchanged - the golden fixtures
did not move, which is the evidence that the descriptor, not the installer,
was incomplete.

#2218 is unaffected: agents are not trigger-bearing, so the wider row does not
introduce a new shadowing case.

Records the warning that an incomplete descriptor is invisible while a second
code path silently does its work, and only surfaces when the two are forced
into agreement.

* fix(#2875): close review findings across staging, agents and the parity harness

Two independent reviews of this branch found defects the local gates missed.

Security: a dangling symlink at a migration destination allowed writing
outside configDir - the same class this change claimed to close, missed at the
terminal write of the flow being added. The staging-root resolver threw as the
first statement of install and uninstall, so a hostile symlink bricked both,
and symlinked-configDir users lost uninstall as well as install; it now
degrades instead of aborting. Recovery gained a source-side symlink check and
now refuses a relative destDir, which resolved against cwd. Converter dispatch
gained a runtime allowlist - lint-time validation stopped mattering once this
branch promoted that dispatch from the surface path to real installs.

Correctness: claude --local --minimal exited 1 because the minimal profile
legitimately yields zero agents and the new path treated that as a failure.
cline --local silently lost its agents - its descriptor declared none while
the deleted loop wrote them unconditionally. The agents prune was widened to
any gsd-* entry and destroyed user files it never owned.

The parity harness, on which the migration's safety argument rested, drove a
synthetic registry and never byte-compared the shipped descriptors; two of its
trap rows could not fail. It now drives the real registry across 13
runtime-scope rows including kimi-code and cline-local, and its red-proof is
demonstrated by corrupting a live capability.json. Three goldens that had
encoded the cline regression as expected behavior were corrected.

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

* fix(#2875): close findings from both mandated review engines

/security-review found the staging source-side walk honouring
GSD_ALLOW_SYMLINKED_DEST, an opt-in documented as relaxing only the write
destination. A symlinked files/ component dereferenced because
copyPreservingSymlink lstats the leaf only, so an intermediate link is
followed. The source walk no longer honours the opt-in; the destination check
still does.

/code-review spec axis found this branch had reintroduced its own bug:
migrateLegacyDevPreferencesToSkill's new symlink refusal threw unguarded after
the legacy dir was wiped and before the staged batch was restored, so a
planted symlink bricked uninstall permanently and orphaned the batch. Refusal
kept, abort removed.

kimi-code local silently lost its agents, the same class as the cline bug, and
the parity harness recorded that exclusion as intentional - the third test in
this branch to pin a regression as correct.

--minimal now creates an empty agents/ dir that never existed. Behaviour
restored rather than softening the changeset, so its byte-identical claim
stays true.

Standards axis: try/finally removed from twelve test bodies, fast-check
properties added for parseOwnerPid, boundary coverage at the grace window and
the ancestor-probe depth, a parity assertion for the staging-root helper
duplicated across two files, and the 8-deep config walk deduplicated.

Records 60-review.json with every finding and disposition from five passes,
including the smells left unfixed and why.

* fix(#2875): prune stale agents unconditionally in minimal mode

The previous round stopped an empty agents/ directory being created when the
resolved profile yields no agents. That was implemented by skipping the agents
kind entirely, which also skipped its stale-agent prune - so a full to minimal
downgrade left stale gsd-* agents behind.

The deleted inline loop pruned unconditionally and only skipped writing. Those
are three separate conditions, not one: prune always, write only when there is
something to write, create the directory only when writing.

Both call sites now run _removeGsdEntries before the empty-staged early exit.
The symlink-escape guard moved with it, since the prune also touches dest.
Codex .toml agents and the config.toml stanzas are cleaned again, and
user-owned agents are still preserved.

The agents/ directory is left in place after a prune empties it, matching
every sibling kind - none of them remove the destination directory itself.

Golden fixtures confirmed byte-identical: the prune is a no-op on a fresh
install, so fixture generation is unaffected.

* docs(#2875): document interrupted-install recovery for user-owned files

The durable-staging fix is invisible to the user it protects. Someone whose
install died mid-flight has no way to know USER-PROFILE.md was staged before
the delete, that the next run restores it, or that recovery happens at the
start of that run rather than in the background.

Written as the task the user has - finish the interrupted command - rather
than as a description of the mechanism, and states what it will not do:
overwrite a file already present, or touch staging belonging to another
install still running.

* test(#2875): assert the J8 model override without building a regex

CodeQL flagged incomplete string escaping: the assertion interpolated the
override value into a RegExp while escaping only forward slashes, which is
meaningless in a constructor, leaving real metacharacters unescaped.

The failure direction was the dangerous one - a metacharacter would have made
the match more permissive, so the row would pass when it should fail. That
matters here because J8 exists precisely because an earlier revision was a
tautology; the rewrite reintroduced a different way for the same assertion to
stop discriminating.

Replaced with a line-wise exact match, so no regex is constructed at all.
Swept the other test files this branch adds; no sibling instances.

lint:ci passed on the original - lint-no-adhoc-regex-escape matches a full
metachar-escape copy, so a single slash replace slipped under it.

8a56595700 docs(#3574): record ADR-3574 install materialization primitives (#3575)
* docs(#3574): record ADR-3574 install materialization primitives

Epic #2866 phase 6 was scoped on the premise that materializing a layout
is implemented three times and should become one module. Measured against
the tree, the premise does not hold: the three sites overlap in shape and
diverge in mechanism.

applySurface prunes by allow-list precisely so it structurally cannot
delete a user's files. installRuntimeArtifacts wipes a prefix-scoped set
and restores a snapshot. A single writer has to pick one, and picking
either trades a working guarantee for a different one.

So the ADR declines phase 6's first acceptance criterion and says why,
because the next reader who notices three similar loops should find this
file rather than rediscover the conflict. What is extracted instead is the
genuinely shared part: durable user-artifact staging for #1874-F19, reusing
the migration primitive that copies strictly before delete and never
dereferences a symlink, plus the retired-kind prune both callers already
share. The agents bypass closes on its own terms.

Two of the issue's premises were also stale: ten runtimes have already
migrated off the inline agent dispatch, and the duplication comment's
deliberate-until condition is partly met.

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.

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.

* 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.

Refs #3409

* 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.

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

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

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

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

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

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

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

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

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

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

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

Three walls matter more than the new coverage:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Implements ADR-3408 section 8.3 as amended.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Two spec-review gaps, both real.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Measured, not assumed:

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

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

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

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

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

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

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

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

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

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

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

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

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

Implements ADR-3408 sections 8.1, 8.2 and 8.6.

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

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

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

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

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

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

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

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

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

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

Also adds the changeset fragment.

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

Standards axis, both hard violations:

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

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

Contract tension, resolved rather than left:

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

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

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

Isolated security review, MEDIUM, confidence 8/10.

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

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

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

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

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

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

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

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

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

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

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

  actual   'current_phase_name'
  expected 'current_plan'

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

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

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

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

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

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

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

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

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

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

* docs(#3467): adr-3408 state.md write-path behavior contract

* docs(#3467): correct write-seam caller list and adr heading depth

Review findings from the Standards and Spec axes, fixed in place:

- ADR behavior contract demoted from H2 to `### 8` with `#### 8.x`
  subsections, matching ADR-3180's `### 7` / `#### 7.1` precedent the
  front matter claims to follow.
- CONTEXT.md placed the STATE.md factory-reset primitive at
  verify.cts:1925. It moved to health-diagnostic.cts:337 when
  cmdValidateHealth migrated onto the rule table (#3309); verify.cts
  now has no writeStateMd call. The design intent was correct — only
  the address was stale.
- A repo-wide scan found three direct writeStateMd callers, not two:
  cmdStateSync, cmdMilestoneComplete, and the REGENERATE_STATE remedy.
  The last is documented as a sanctioned permanent exception — it is
  a factory reset, so preservation would restore the values it was
  invoked to discard.
- phase.cts comment citation corrected to :2953-2957.
- Amendment 4 attribution corrected: the recorded owner-file exemption
  failure is roadmap-parser.cts; the state.cts transfer is this ADR's
  own extrapolation.

Updates docs/adr/3180-planning-semantic-model-single-owner.md to
reflect Phase 10 shipping: §8.1 status Required -> Enforced (Phase 10,

issue/status backfilled, and a new Amendment 9 recording the guard's
real baseline (15 distinct raw-read sites, 21 total acknowledged
occurrences in cmdValidateHealth) against the issue's own vaguer
estimate, per Amendment 4a's standing "N found by the guard, never

1bc7f7e6b0 test(#3339): fold the state/phase/dispatch & model-profile issue-* cluster — Wave 7
Folds 9 legacy issue-*.test.cjs regression files (140 test() blocks) into
their module's main suite, per H3 (#3315) of the test-hygiene epic (#3053).
LAST of 4 issue-* waves — closes out the 74-file fix-*/issue-* backlog
(pending BUG_FILE_RE extension, held for a follow-up commit until Wave 6
is confirmed merged, per the epic's own zero-backlog precondition).

- issue-2828-flat-roadmap-total-phases.test.cjs (1) + issue-3204-state-
  writer-phase-count.test.cjs (21): both target state-document.cjs
  buildStateFrontmatter via different CLI entrypoints — merged jointly
  into state-document.test.cjs, 0 dropped.
- issue-2945-phase-complete-checkbox-rollback.test.cjs (4) + issue-2949-
  phase-complete-stage3-sentinel.test.cjs (4): both target phase.cts
  cmdPhaseComplete; issue explicitly warned of overlap — verified
  disjoint fixtures/assertions, 0 dropped, merged into phase.test.cjs.
- issue-2927-reviewer-lane-overlay-invocation.test.cjs (10) merged into
  review-lane-descriptor.test.cjs.
- issue-2939-dispatch-flatten-maxdepth.test.cjs (9) merged into
  host-integration.test.cjs, 2 dropped as verified exact duplicates.
- issue-2977-frontmatter-bom.test.cjs (5) merged into frontmatter.test.cjs.
- issue-2045-third-party-skills-surface.test.cjs (6) merged into
  capability-loader.test.cjs.
- issue-2517-runtime-aware-profiles.test.cjs (80, the largest single
  fold in the epic) merged into model-resolver.test.cjs, 1 dropped as a
  verified true duplicate (checked against src/model-resolver.cts logic,
  not just title similarity).

Fixed a genuine eslint irregular-whitespace finding: a literal BOM
character embedded in a doc comment (pre-existing content from the
original #2977 source, illustrating what a BOM looks like) — replaced
with a readable U+FEFF notation.

3 stale doc references found and fixed (docs/adr/2313, 3180, 443).

Zero net test-coverage loss. No production code changed.

aee83c8e9e test(#3337): fold the manifest & package-identity issue-* cluster — Wave 5 (#3378)
* test(#3337): fold the manifest & package-identity issue-* cluster — Wave 5

Folds 6 legacy issue-*.test.cjs regression files (120 test() blocks) into
their module's main suite, per H3 (#3315) of the test-hygiene epic (#3053).
Second of 4 issue-* waves.

- issue-766-plugin-manifest.test.cjs (50 tests): pure rename (git mv) into
  plugin-manifest.test.cjs, sole comprehensive suite for its module.
- issue-844-manifest-version-sync.test.cjs (14 tests, rename basis) +
  issue-1855-marketplace-manifest.test.cjs (17 tests, merged in): both
  target scripts/sync-manifest-versions.cjs via non-overlapping describe
  blocks (generic engine vs. marketplace.json-specific), now
  manifest-version-sync.test.cjs, 31 tests, 0 dropped.
- issue-498-identity-drift-lint.test.cjs (8 tests, rename basis) +
  issue-498-package-identity.test.cjs (17 tests, merged in): both target
  package-identity.cjs's surface from different angles (lint-side drift
  detection vs. derive/slugify), now package-identity.test.cjs, 25 tests,
  0 dropped.
- issue-607-cache-lineage.test.cjs (14 tests) merged into the existing
  gsd-statusline.test.cjs, matching its already-established fold-wrapper
  convention from prior waves.

Learned from Wave 4: fold agents checked src/** (not just docs/ and
gsd-core/references/) for stale filename references — found and fixed 5
across 3 ADR docs (766, 2121, 457), zero in src/ this time.

Zero net test-coverage loss. No production code changed.

* test(#3337): fix orthogonal-review findings — Wave 5 fold

Standards-axis review found real issues in the just-folded
manifest-version-sync.test.cjs, both fixed here:

- The folded:issue-1855-marketplace-manifest block omitted its own
  test/describe/assert/fs/path/os requires, silently closing over the
  #844 basis section's outer-scope bindings instead of declaring its own
  dependencies — inconsistent with every other fold block in this wave.
  Restored the local requires the original issue-1855 file declared.
- Merging two independently-lettered legacy files (each A-F) left
  duplicate top-level describe() labels (two "A:", two "B:", two "C:").
  Renamed the folded-in #1855 labels (A2/B4/C2) to make every top-level
  label in the file unique.

No test() count changed (31). No production code touched.

ad07f76a31 test(#3336): fold the installer & runtime surface issue-* cluster — Wave 4 (#3376)
* test(#3336): fold the installer & runtime surface issue-* cluster — Wave 4

Folds 10 legacy issue-*.test.cjs regression files (79 test() blocks) into
their module's main suite, per H3 (#3315) of the test-hygiene epic (#3053).
First of 4 issue-* waves (following the 3 fix-* waves, all merged).

- 1 file with no prior target coverage: renamed (git mv) into
  legacy-cleanup.test.cjs (sole comprehensive suite for that module).
- 9 files merged into 6 pre-existing suites: golden-parity-single-source,
  runtime-artifact-layout-surface, codex-config (4 sources merged jointly
  in one pass per the issue's own instruction, to catch overlap between the
  4 sources themselves, not just against the pre-existing target — zero
  overlap found, all 20 blocks additive), runtime-config-adapter-registry
  (1 of 10 source blocks dropped as a proven subset of existing coverage),
  cline-install, install.test.cjs.

Incidental fixes required to keep this wave's own ratchets green:
- Fixed a stale ADR doc reference (docs/adr/1235) to a folded-away filename.
- scripts/lint-allow-test-rule-refs: pruned 4 stale allowlist entries for
  renamed/merged-away files, cited 2 previously-uncited allow-test-rule
  comments that surfaced as "new" only because their file path changed,
  added 1 fresh allowlist entry for a pre-existing uncited comment that
  predates this PR, and tightened the exemption-file ceiling 309 -> 305
  to match the real post-fold high-water mark.

Zero net test-coverage loss. No production code changed.

* test(#3336): fix orthogonal-review findings — Wave 4 fold

Standards-axis review + Memtrace graph pass found real issues in the
just-folded suites, all fixed here:

- Standardized the fold-wrapper convention (block-scoped __foldDescribe)
  across golden-parity-single-source.test.cjs, runtime-artifact-layout-
  surface.test.cjs, runtime-config-adapter-registry.test.cjs, and
  cline-install.test.cjs to match the pattern already used by
  codex-config.test.cjs and install.test.cjs in this same wave (and by
  earlier folds elsewhere in the epic) — repeats the exact inconsistency
  Wave 3 (#3335) already fixed once in this epic.
- Fixed a stale allowlist entry's alphabetical position (cosmetic, not
  tool-gated, caught by review anyway).
- Fixed two stale test-filename references in PRODUCTION code comments
  (src/capability-writer.cts, src/runtime-config-adapter-registry.cts)
  caught by lint-removed-but-needed — a class of stale reference this
  wave's fold agents didn't check for, since they were scoped to docs/
  and gsd-core/references/ only, not src/. First fix attempt wrongly
  edited the gitignored gsd-core/bin/lib/*.cjs BUILD OUTPUT instead of
  the tracked .cts source; caught and corrected before commit.
- Fixed one remaining stale doc reference in docs/adr/1235 (a prior
  partial fix in this same wave missed it).

No test() count changed in any file. No production code BEHAVIOR
changed — comment-only fixes in src/.

0396d9cab1 enhance(#2483): stop the claude reviewer lane from inheriting CLAUDE.md + auto-memory (#2493)
* enhance(#2483): env-guard the claude reviewer leg against CLAUDE.md injection

The claude reviewer in workflows/review.md was a bare headless `claude -p`
spawn run from the project cwd, so it inherited the invoking user's global
CLAUDE.md, the project CLAUDE.md, and Claude Code auto-memory.

That made it the only reviewer leg seeing anything beyond the prompt file.
gather_context assembles PROJECT.md, the roadmap section, every PLAN file,
CONTEXT.md, RESEARCH.md and REQUIREMENTS.md into the prompt before any
reviewer runs; the gemini leg receives only that prompt and the codex leg
runs --ephemeral. Beyond the measured ~4k tokens/spawn, the asymmetry cuts
at the workflow's own premise: "independent review" meant something
different for the claude leg than for the other two.

Guard both dispatch lines with a per-invocation
`env CLAUDE_CODE_DISABLE_CLAUDE_MDS=1`. `env`, never `export` — the flag
must not leak into the orchestrating session (which may itself be Claude
Code on the SELF_CLI="auto" path) or into any later spawn.

review.md is the only claude -p call site in the installed tree, so this is
two lines on one surface. The self-skip logic is untouched.

* enhance(#2483): fix CRLF-fragile split and regenerate workflow baselines

Two CI failures from the first push, both mine:

1. lint-tests: the new regression test split readFileSync content on a
   literal "\n". On a Windows git-autocrlf checkout that leaves a trailing
   "\r" on every line (local/no-crlf-fragile-split). Use .split(/\r?\n/).

2. golden-install-parity / workflow-size-budget / workflow-compat: editing
   gsd-core/workflows/review.md changes its content hash and byte size, and
   both are pinned in committed baselines. Regenerated via the repo's own
   generators (npm run size:baseline, npm run gen:golden).

The regenerated diffs are review.md-only: exactly one hash line per
golden-install-parity fixture and one size entry in workflow-size-baseline
— no unrelated drift swept in.

Full suite now green locally: 2113 pass, 0 fail, 3 skipped (run with HOME
and CLAUDE_CONFIG_DIR overridden to throwaway dirs; live profile verified
untouched afterward).

* enhance(#2483): adapt guard-test matcher to the effort-args dispatch reshape

The effortSurface wiring (#2481) reshaped the bare-model dispatch to
`claude $CLAUDE_EFFORT_ARGS -p -`; the invocation matcher's dash-first
form could no longer see it, and the count assertion failed exactly as
designed. The matcher now tolerates variable expansions between `claude`
and its first literal flag. Negative-controlled both ways: a stripped
guard and a deleted dispatch line each still fail.

* enhance(#2483): also guard the claude leg against auto-memory injection

CLAUDE_CODE_DISABLE_CLAUDE_MDS suppresses CLAUDE.md file loading;
auto-memory is an independently-toggled mechanism with its own flag.
Add CLAUDE_CODE_DISABLE_AUTO_MEMORY=1 to both dispatch lines, correct
the docs/COMMANDS.md and changeset claims that credited the first flag
with covering auto-memory, and extend the regression test to require
both flags on every claude invocation (negative-controlled: 2/4
assertions fail with the new flag removed).

* enhance(#2483): match the claude binary in command position, not argument position

The line-oriented invocation matcher counted any line where the token
`claude` was followed by a flag. #2589 (landed on next as 920a5f3f)
reshaped the effort-args lookup from

  --host claude 2>/dev/null | jq -r '.effort_argv_string // ""'

to

  --host claude --pick effort_argv_string

which put a flag immediately after `claude` and made the config query
read as a third claude dispatch, failing the count assertion.

The defect class is a binary name in *argument* position being read as a
command. Fixed at the class rather than the instance: tokenise the line
and skip any `claude` whose preceding token is a flag. That also covers
the latent sibling one line away in review.md (`command -v claude`),
which escaped today only because its next token is a redirect.

Negative-controlled four ways: stripping CLAUDE_CODE_DISABLE_AUTO_MEMORY=1
fails, stripping the whole env guard fails, adding a genuine third
unguarded dispatch (`timeout 900 claude --output-format text -p -`) still
fails — so the narrowing did not blind the matcher to reshapes, which is
the property the count assertion exists for — and the pre-#2589 jq form of
the lookup still passes, so the matcher is not pinned to today's base.

* enhance(#2483): carry the claude reviewer's memory guard as declared lane data

ADR-2782 Phase 5b replaced the hand-authored per-CLI dispatch legs in
review.md with the declared lane table, so the two `env`-prefixed shell
lines this PR previously added no longer have a surface to live on. The
guard is reimplemented where the lane contract now lives.

`SpawnInvoke` gains an optional `env`, the claude lane declares the pair,
the resolver folds own string-valued entries into `SpawnPlan.env` (absent
or empty resolves to null, so the runner has one shape to test), and the
runner passes it to spawn. Production merges it OVER `process.env` into a
fresh object for that one child, so nothing reaches the orchestrating
session or any other lane in the run.

Declared data rather than a handler (D6): the pairs are static per lane,
which is precisely what the manifest vocabulary is for. The capability
manifest carries the same field, because the lane-fidelity test compares
manifest and descriptor over the union of `invoke`'s keys.

The regression test is rewritten against the resolver and runner rather
than review.md's text. It gains the property the source-text assertions
could only approximate: that `process.env` is never mutated.

Scope boundary, asserted rather than left in prose: `env` is not part of
the trust-disclosure surface, which is safe only while no manifest body
reaches the resolver — the registry's reviewer bodies contribute slugs to
the parity check and execution resolves from `REVIEWER_LANES`. The new
test fails first if that ever changes.

* enhance(#2483): restate the guard's mechanism in the docs and changeset

Both described the fix as two `env`-prefixed dispatch lines, which is the
surface ADR-2782 Phase 5b removed. The user-visible behaviour is
unchanged; the carrier is not, and a changeset that ships a description
of a mechanism the tree does not have is a CHANGELOG entry nobody can
verify against the code.

* enhance(#2483): cover the production spawn wiring end to end

The unit tests stop at the runner's `deps.spawn` seam — every one injects
a spy. Production supplies that seam in `gsd-core/bin/gsd-tools.cjs` as a
hand-written object no test constructs, so the chain could be correct all
the way to `SpawnPlan.env` and the merge could still be wrong or absent
with the suite green. Deleting those four lines was the one mutation that
left every other control silent.

This runs the real `spawnSync` through `gsd-tools review-lane invoke`,
with a `claude` shim on PATH that records the environment it was handed.
It asserts both halves in one test: the pair arrives, and an unrelated
inherited variable survives — a wiring that REPLACED the environment
rather than merging over it would satisfy the first and break every
lane's PATH and HOME.

POSIX-only; mediating a Windows `.cmd` shim is a separate concern the
repo already tests on its own.

Noted rather than fixed: `timeout`, `killSignal`, `maxBuffer` and
`shell: false` on that same object are equally uncovered. That is the
epic's gap, not this change's, and closing it is not in scope here.

* enhance(#2483): validate the invoke.env shape and register it as spawn-only

`env` was the one spawn-invoke field with no shape enforcement: every sibling in
`validateSpawnInvoke` is checked, and a manifest declaring `env` as an array, a
string, a number, or an object with non-string values passed validation in
silence. That matters more than an ordinary schema gap here, because
`resolveLanePlan` DROPS a non-string value rather than coercing it — so an
unvalidated manifest declares a pair that never reaches the spawn, which is the
failure a memory guard can least afford.

Two registrations, not one. `env` was also absent from
`SPAWN_ONLY_INVOKE_FIELDS`, which is the list the openai-http arm rejects
against — so `invoke.env` was accepted on a transport that issues an HTTP POST
and has no child environment at all. It was the only spawn-shaped field accepted
there; the other six each produce two errors. Self-found while sweeping the
class, not raised in review.

Keys are held to the portable POSIX environment-name grammar. That is a policy,
not a claim about what an environment can hold: measured, only NUL is actually
rejected by `spawnSync`, while `=`, a leading digit, a dash and a space are all
carried through to the child (an `A=B` key arrives as the raw entry `A=B=value`).
They are refused because a name outside the grammar is not portably addressable
by the program meant to read it.

`__proto__` is refused for a different and concrete reason. It passes that
grammar and is a real own key once a manifest is JSON-parsed, but assigning it
onto a plain accumulator goes through the inherited `__proto__` setter rather
than creating an own property — and for the string values this field permits the
setter is a no-op that does not even change the prototype. The pair would
validate and then simply vanish before the spawn. (An environment CAN carry a
literal `__proto__` entry; this is about the resolver's accumulator, and the
error message says so.)

Deliberately narrower than the sibling reserved-name guards in this file, which
also reject `constructor`/`prototype`: those guard bracket lookups that resolve
prototype members, whereas this reads via `Object.keys` plus an own-value read,
where `constructor` assigns as an ordinary key the spawn could carry.

`effortChannel` is deliberately left in neither field list: ADR-2782 D2 defines
it for both transports, so it is shared rather than spawn-only.

Reversion-controlled, three mutations, all three fire a named test: dropping
`env` from the discriminator fails `httpTransportRejectsEnv`; removing the
`__proto__` arm fails `envRejectsProtoKeyThatWouldSilentlyVanish`; disabling
the block fails four.

(#2483)

* enhance(#2483): amend ADR-2782 D2 for the invoke.env vocabulary widening

D2 records the spawn `invoke` shape as a closed vocabulary, and its Amendments
section carries a dated entry for every prior widening (Phase 1 #2794, Phase 2
corrections #2795, Phase 5b #2799). This change extended that vocabulary in code
without touching the ADR governing it, so the ADR contradicted the
implementation — and the repo's own convention, recorded in CONTEXT.md, is that
the ADR is amended in the same PR precisely because the prior widenings did it
correctly.

Adds the `invoke.env` row to the D2 table and a dated Amendments entry.

The entry also corrects the authority this change cited. The source comment
pointed at D6, which governs the closed `handler` enum — imperative behavior
admitted first-party — and says nothing about the `invoke` field vocabulary.
That is D2's territory, so the citation never covered the gap.

Two claims are corrected rather than restated, both about the trust boundary
that justifies leaving `env` out of the D5 disclosure signature:

- The regression test does not enforce that boundary. On one forged lane it
  shows the resolver folds whatever it is handed, so a future path feeding it
  manifest lanes would not make any assertion in that test fail. Its comment
  claimed it "will fail first"; that was wrong, and both the comment and the
  ADR now say the boundary is a property of the production call chain instead.
- The ADR is internally inconsistent on whether third-party manifest lanes
  execute at all: Consequences says adding a reviewer needs "no core patch",
  while `gsd-tools.cjs` rejects every slug absent from the first-party
  REVIEWER_LANES map. CONTEXT.md, `workflows/review.md` and the resolver's own
  header take the first view. #2483 did not create that inconsistency and does
  not resolve it; the entry records it rather than settling it in its own favour.

(#2483)

* enhance(#2483): document invoke.env in the capability-manifest reference

ADR-2782 points capability and plugin authors at
`docs/reference/capability-manifest.md` as where the lane vocabulary must be
visible, and its `invoke` row enumerates the spawn sub-shape field by field.
`env` was absent from that table while being part of the real shape, so the one
document a third-party capability author would actually consult to learn the
field exists did not mention it.

Squarely Diataxis reference material — a field-by-field schema description — so
it goes here rather than in the user-facing prose, which was already updated.
States the constraints a manifest author can actually trip, and is explicit that
the name grammar is a portability policy rather than an OS limit, so a reader
does not take it for a claim about what an environment can hold.

(#2483)

* enhance(#2483): disclose and sign the reviewer lane's env and residual invoke fields

`invoke.env` was undisclosed at install time. That was defensible while manifest
lanes could not execute — the premise this PR's own ADR amendment recorded — and
#2927/#3062 retired it: `routeReviewLane` now merges installed overlay `reviewer`
bodies into its lane map via `mergeReviewerLanes`, which is a field-identical merge
by ADR-2782 D1 and deliberately does not deep-validate. An overlay's whole `invoke`
therefore reaches `resolveLanePlan`, and `env` reaches the spawned child. A consented
third-party capability could set `NODE_OPTIONS=--require ./evil.js` on a reviewer lane
with no install-time disclosure and no re-consent.

The same file already decided what `env` means in a manifest: MCP servers fold it into
the disclosure signature and render each key and value in the consent prompt, with an
inline rationale naming this exact shape. Reviewer lanes get the identical treatment.

`env` was the ninth unsigned invoke field, not the first. `defaultHost` (the manifest's
OWN fallback egress host, used whenever the config key resolves to nothing),
`path`, `outputChannel`/`outputArg`, `modelArg`, `effortChannel` and `modelDiscovery`
all reach `resolveLanePlan` and none was bound. Enumerating a ninth name leaves the
tenth open, so the lane signature carries a RESIDUAL of every other declared `invoke`
key — the completeness backstop `rawConfig` already gives the MCP line (#1459 finding 5),
and the "sign the whole object" remedy the recorded decision on this class prefers.

`defaultHost` is also rendered: `resolvedHost` comes from user config, so a lane whose
key is unset displayed "(unresolved …)" — which reads as "no destination" — while the
runtime egresses the plan and review text to the address the manifest picked.

D4.5 is preserved one level down: the extra element is appended ONLY when the lane
declares something beyond the eight already-bound fields, so an env-free lane's
signature stays byte-identical and no already-consented capability is re-prompted for
a field it does not use. A lane that does declare one re-consents, which is the point.

Execution-primitive env names are FLAGGED in the prompt, not refused in the validator.
A denylist cannot be the boundary here: `PATH` alone is a complete execution primitive
for a spawn lane and can never be refused, the child is an arbitrary third-party binary
so the true set spans every interpreter's injection vars, and the MCP `env` this mirrors
refuses nothing and discloses everything. Missing a name costs a quieter line, never a
boundary.

Refs #2483.

* enhance(#2483): exercise the real overlay merge path in the guard test

The test named for the manifest/first-party boundary did not test it. It built a
forged lane locally, handed it straight to `resolveLanePlan`, and asserted that
`REVIEWER_LANES` did not contain it — so no assertion in it depended on the claim its
name made, and a code path that fed manifest lanes to the resolver would not have made
it fail. Its own comment said as much, and named the production chain as the real
carrier of the guarantee: "gsd-tools.cjs builds its lane map solely from REVIEWER_LANES".

That sentence is now false. #3062 merged overlay reviewer bodies into that map, so the
test's premise and its subject both moved.

The replacement routes through `mergeReviewerLanes` — the real helper the production
path calls — and asserts the overlay lane is admitted, resolves, and carries its `env`
into `SpawnPlan.env`. That makes the security property falsifiable instead of narrated.
It then asserts what now backs it: the env is disclosed on the surface, rendered key
and value in the consent prompt, flagged when the name is an execution primitive, and
bound to the signature so a value change, an addition, or a removal each force
re-consent.

Three further cases, because the finding's generative half is what stops it recurring:
the residual backstop is asserted against five fields including one that does not exist
(`aFieldThatDoesNotExistYet`), so a future vocabulary widening cannot silently re-open
this; a fully-enumerated lane is pinned to its original 8-tuple, which is what keeps the
fix from re-prompting every consented capability; and an http lane's manifest-declared
`defaultHost` is asserted to reach both the prompt and the signature.

Reversion-controlled, seven mutations, all seven fail a named test: env dropped from the
surface, the prompt's env line removed, the execution-primitive warning removed, the
signature's extra element never appended, the residual emptied, the defaultHost line
removed, and the declares-something test un-widened. The last of those was SILENT on its
first run and its test was written in response, then the control re-run.

Refs #2483.

* enhance(#2483): correct the ADR amendment's manifest-lane premise

The amendment argued `env` needed no D5 disclosure because a manifest's `invoke`
fields never reach `resolveLanePlan`. That was true when written and #3062 retired it
22 hours after this branch's last commit: `routeReviewLane` now builds its lane map
from `mergeReviewerLanes(REVIEWER_LANES, loadRegistry({includeInstalled: true}))`, and
D1's no-translation-layer rule makes that a field-identical merge, so an overlay's
whole `invoke` reaches the resolver and executes.

The entry had named this exact trigger — "were manifest lanes ever made executable,
`env` must join the disclosed surface in that change, and nothing here will trip if it
does not." Nothing tripped. The premise is rewritten to current truth rather than
annotated, because an ADR is read in fragments and a superseded paragraph left standing
reads as live reasoning to the next author; a one-line dated tombstone points at git for
the withdrawn text.

The rewritten entry records four things the first draft could not: that the enumeration
itself was the defect (`env` was the ninth unbound `invoke` field, and `defaultHost` and
`path` are egress-relevant on their own), that the residual is what closes the class,
that D4.5's byte-identical-signature property is preserved by appending the residual only
when a lane declares something beyond the eight bound fields, and that consent — not
shape validation — is the boundary, since no honest env denylist can exclude `PATH`.

It also closes the internal inconsistency the previous entry could only record. This ADR,
`CONTEXT.md`, `gsd-core/workflows/review.md` and `resolveLanePlan`'s own header all said
overlay lanes reach the resolver while the runtime said otherwise; #3062 resolved that in
the documents' favour, which is what makes the disclosure mandatory rather than defensive.

Refs #2483.

* enhance(#2483): record in the manifest reference that invoke fields are consent-bound

`docs/reference/capability-manifest.md` is the field table ADR-2782 points capability
authors at, and it described `invoke` purely as a schema. A third-party author reading it
could not learn that everything they declare there is shown to the user at install and
bound to the consent signature — which is exactly what they need to know now that an
overlay reviewer lane executes (#2927/#3062).

States the two things the schema alone cannot: that `env` and `defaultHost` are named in
the consent prompt and the rest is covered by a residual, so any change to a declared
`invoke` field forces re-consent; and that `env`'s validation is a portability policy
rather than a safety boundary, since `PATH` is a complete execution primitive and cannot
be refused. Names that are execution primitives are highlighted in the prompt instead.

Refs #2483.

* enhance(#2483): add a Security changeset for the reviewer-lane disclosure

The existing fragment describes the enhancement this PR was opened for and stays as it
is. The disclosure fix is a separate user-visible change of a different type: a
capability declaring `invoke.env` or `invoke.defaultHost` will ask for consent once
more, and users are entitled to read why in the changelog rather than discover it as an
unexplained prompt.

Type is `Security` rather than `Changed` because the entry describes a closed
code-execution disclosure gap, not a behaviour adjustment.

Refs #2483.

* enhance(#2483): correct this round's own claim about who gets re-prompted

Self-found while auditing the round's claims before publishing them. The changeset and
the ADR entry both stated that a capability declaring `invoke.env` or `defaultHost`
"will ask for consent once more". That is wrong, and it overstated the cost of the fix
in the one direction a maintainer would have had to take on trust.

A code change to `disclosureSignature` re-prompts nobody. `hasProjectConsent` matches on
the recomputed bundle `contentHash` — the signature has not been the security binding
since #1459 CB-1/CB-2 — and the upgrade path's `executableSetChanged(old, new)` compares
two disclosures both computed by the CURRENT code, so widening the signature moves both
sides of that comparison equally. First-party capabilities never reach the path at all:
the install flow blocks a first-party id before trust evaluation.

What the widening actually buys is forward-looking, and is the real argument for it: an
upgrade whose manifest edits a declared `invoke` field now registers as an
executable-surface change and re-consents, where before it could change what the lane
runs in silence.

Also measured and recorded, because the D4.5 property was stated more strongly than it
deserved: of the twelve first-party reviewer capabilities, ZERO are in the
byte-identical-signature class — every real lane declares at least `effortChannel`. The
property is a guarantee about minimal lanes, not a description of the fleet, and the ADR
now says so.

Refs #2483.

* enhance(#2483): sign and disclose the probe binary and the lane's outer fields

Found by this round's own adversarial review, and it is the same defect one level out:
the `invoke` residual cannot reach the lane body's OUTER fields, and `probeLane` SPAWNS
`probe.binary` with `--help` before dispatch (`review-lane-runner.cts`, the
`command-exists`/`command-capability` arms). An overlay naming an arbitrary probe binary
therefore executes it — unsigned and undisclosed, exactly as `invoke.env` was, and
reachable on the same #3062 path.

The lane element now carries a second residual over the outer fields, and the probe
binary is shown in the consent prompt when it differs from the dispatch binary — it is a
program that runs, and the user is entitled to see it.

TWO fields stay excluded, and that is a decision rather than an omission:
`reviewsSection` and `timeoutFloorMs` are ADR-2782's cosmetic carve-outs (matrix
A10/A13), where re-consenting would present a prompt carrying no security information.
A test pins that they remain excluded, so a later widening cannot quietly reverse D4.5
while claiming to complete this fix.

Also corrects a miscount introduced by the previous commit: the source comment said the
enumeration had fallen behind by "seven fields" and omitted `fallbackModel`, while
asserting `env` was the ninth. `resolveLanePlan` reads twelve `inv.*` fields and four
were bound, so the number is eight. The comment now states the derivation rather than
just the total.

Reversion-controlled: emptying the outer residual fails "repointing the probe binary must
force re-consent"; removing the render line fails its own named assertion.

Refs #2483.

* enhance(#2483): refuse execution-primitive env names as defence in depth

Adopts the review's B5 after this round's own adversarial pass refuted my reason for
declining it. I had argued a denylist was worthless because `PATH` can never be refused.
That was wrong on the facts: no shipped reviewer manifest declares `PATH`, so it can be
refused, and it is the most complete primitive in the set — repoint it at a directory
holding a fake binary and the declared `invoke.binary` is irrelevant. A list that cannot
be exhaustive can still close the highest-confidence, lowest-legitimacy routes.

So the validator now rejects `PATH`, `NODE_OPTIONS`, `LD_PRELOAD`, `DYLD_INSERT_LIBRARIES`,
`BASH_ENV`, `PYTHONPATH`, `PERL5OPT`, `RUBYOPT`, `GIT_SSH_COMMAND`, `JAVA_TOOL_OPTIONS`
and their siblings on a reviewer lane. A lane needing a specific executable declares an
absolute `invoke.binary` instead of reshaping the child's environment.

The comment states plainly that this is defence in depth and NOT the boundary — the
boundary is install-time consent, which discloses every declared pair and binds it to the
signature, so an unlisted name is still SEEN before it runs. That framing is load-bearing:
a future reader who mistakes the denylist for the control will under-invest in the one
that is, which is the failure mode I was trying to avoid by declining it outright.

Two tests: the rejection itself across ten names, and a guard asserting no shipped
reviewer capability declares a denied key — so if the list ever outgrows its evidence,
that surfaces as a decision rather than a silent removal.

Refs #2483.

* enhance(#2483): fix two stale D5 enumerations elsewhere in the ADR

The previous commit rewrote the amendment's premise but swept only the amendment. Two
normative passages earlier in the same ADR still enumerated the old closed field list and
now contradicted it: the `executableSetChanged` trigger list, and the split-binding note
asserting the seven manifest-derived fields were "everything that is SHA-pinned".

That is the failure the rewrite-don't-annotate rule exists to prevent, one section over —
an ADR is read in fragments, and a fragment carries no supersession marker, so a reader
landing on either passage would have taken the superseded enumeration as current.

Both now name the residual as the mechanism rather than restating a list, which is also
what stops them going stale the next time the vocabulary widens.

Found by this round's adversarial review, which grepped the whole document rather than
the section under edit.

Refs #2483.

* enhance(#2483): stop the probe disclosure claiming a spawn that does not happen

The probe line added one commit ago rendered "probes by running: <binary> --help" for
every lane. That is false for `kind: "command-exists"`, which only calls `hasBinary` — a
PATH/filesystem scan that starts no process. Only `command-capability` spawns.

A false statement in a consent prompt is worse than a missing one: the prompt is the
surface a user is asked to trust, and this one overstated what a lane does. Worse, the
test I wrote to prove the fix used `command-exists` — the kind that does NOT spawn — so
it pinned the wrong claim and would have kept the error green forever.

The surface now carries `probeKind` and the two kinds render differently: a spawn is
described as a spawn, a presence check as a presence check. The test exercises both, and
asserts the `command-exists` path never emits the spawn wording.

Also corrects the field-count parenthetical to state its derivation unambiguously —
`resolveLanePlan` reads thirteen `inv.*` fields including `env` (twelve before this PR),
four were bound, so eight were unbound before `env` and nine including it. The bare
"twelve" was true only of the pre-PR tree and read as a claim about the current one.

And retires two comments that argued AGAINST the validator denylist this round then
shipped. Leaving them would have handed the next reader the reasoning for removing it.

Reversion-controlled: conflating the two probe kinds fails a named test.

Refs #2483.

* enhance(#2483): match the reviewer-lane env denylist case-insensitively

The denylist added one commit ago compared exact case, so `Path`, `path`, `node_options`
and `Node_Options` all passed it. Windows environment lookup is case-insensitive, so
those reach the child as `PATH` and `NODE_OPTIONS` — the exact inputs the list names.

An exactly-cased denylist is worse than none: it reads as a control while admitting the
input it was written to refuse, and the next reader has no reason to doubt it. Members
are stored uppercase and the key is folded before lookup; the name grammar already
constrains keys to ASCII, so a plain fold is sufficient.

Reversion-controlled: restoring the exact-case compare fails `envDenylistIsCaseInsensitive`
on `Path`.

Refs #2483.

* enhance(#2483): correct the docs that still described the denylist as absent

Both the ADR and the manifest reference still said `env` carries no denylist and that
`PATH` "can never be refused" — written when that was this round's position, and left
standing after the round reversed it. A reader landing on either passage would have taken
the superseded argument as current, which is precisely the failure the rewrite-don't-
annotate rule exists to prevent.

Both now describe the denylist, name `PATH`'s inclusion and the case-insensitive match,
and keep the limit explicit: the list cannot be complete against an arbitrary child and
disclosure runs before validation, so consent remains the boundary.

The ADR's byte-identical-signature claim is also corrected rather than softened. With the
outer residual in place, a lane producing no residual is one the validator rejects — it
declares no `flags`, `probe`, `emptyOutput`, `evidenceClass`, `requiresBinaries` or
`promptBudgetKey`. So the property is about the ENCODING, not a claim that any real
signature is unchanged, and it is not the argument for the change being safe. That
argument is that consent binds to the bundle contentHash and no existing consent is
invalidated at all.

Refs #2483.

* test(#2483): cover the three new lane disclosure fields in the injection-safety parity guard

The PARITY test in section N exists to catch a renderer field that skips
`renderValueForPrompt` (#3248). Its payload manifest is hand-maintained, so it
covers the fields that existed when it was written — slug, binary, args,
hostConfigKey, handler — and none of the fields this PR adds.

This PR renders three further manifest-supplied values into consent-prompt
lines: `invoke.env` (keys and values), `invoke.defaultHost` and `probe.binary`.
The gap was silent rather than theoretical: with the lane env line reverted to
the pre-#3248 raw form, the whole 948-test lane/capability/trust-disclosure
suite stayed green.

Two manifests, because the shapes render disjoint lines — `defaultHost` only on
the openai-http branch, `env`/`probe` only where declared, and the probe line
only when the probe binary differs from the dispatch binary.

Non-vacuity is asserted on the typed disclosure object and on structural line
counts, not by substring-matching rendered prose: CONTRIBUTING.md forbids raw
text matching on test output, and this section's own header promises structural
assertions only, so a prose match here would have made that promise false.

Negative-controlled three ways against the merged tree, each producing exactly
one named failure: env rendered raw, defaultHost rendered raw, probe binary
rendered raw.

* docs(#2483): extend the #3248 render-site comment to the fields this PR adds

The comment enumerates every manifest-supplied value that must pass through
`renderValueForPrompt`, and it stopped at `handler` — the reviewer-lane fields
that existed when #3248 landed. This PR renders three more (`defaultHost`, the
probe binary, and the env keys and values), so the list understated its own
contract in the one place a future author would check before adding a fourth.

A comment enumerating a closed set is a set that can silently fall behind the
code it describes; the parity test added alongside is what makes the omission
fail loudly rather than read as deliberate.

9341d8b8d3 test(#3334): fold the workflow-dispatch & review-lane fix-* cluster — Wave 2 (#3342)
Folds 15 tests/fix-*.test.cjs regression files (191 test() blocks) into
their module's main suite, per the wave decomposition of #3315 (H3 of
epic #3053). 187 blocks land in 8 existing suites (4 exact-duplicate
cases dropped, documented inline); 4 blocks move via git mv into 2 new
suite files with no prior coverage to merge into. Zero production
behavior change.

Also tightens two H1 (#3313) ratchets that the fold's own file-count
reduction moved past their grace window, per the ratchets' documented
dual failure mode (a stale/too-loose baseline fails exactly like a
novel violation):
- lint-test-file-count.allowlist.json: removes the stale "audit" entry
  (folding fix-2766 into tests/uat.test.cjs drops that module back to
  its 2-file cap).
- lint-allow-test-rule-refs.ceiling.json: lowers maxFiles 314 -> 309,
  the real post-fold high-water mark (gsd-test's own repo-baseline
  test caught this — CI, not a human, found it).

Two orthogonal review passes (Standards+Spec code-review, isolated
security-review) found and this commit fixes two issues before push:
a genuinely-distinct #2287 test case (file-absent vs. file-present-
resolved) that a prior fold pass had wrongly dropped as a duplicate —
restored verbatim into tests/uat.test.cjs; and a missing same-line

80734a9694 chore(#3053): clock-seam ADR-456 amendment + backfill — H2 (#3332)
* test(#3314): backfill deterministic clock-seam coverage (failing-first)

Replaces loose regex/range assertions with exact-value and boundary
tests for the CLI-subprocess and in-process clock-touching call sites
identified by H2's audit (epic #3053): cmdCurrentTimestamp,
_wsParseRetryAfter (commands.cts), cmdInitManager's is_active gate and
cmdInitQuick's quick_id generation (init.cts), and reapStaleTempFiles
(io.cts). The CLI-subprocess-pinned tests are expected RED until a
follow-up commit routes those call sites through realClock so
GSD_TEST_MODE+GSD_NOW_MS can reach them.

* refactor(#3314): route CLI-subprocess clock reads through realClock

cmdCurrentTimestamp, cmdInitManager's is_active gate, and cmdInitQuick's
quick_id generation read Date directly, which the GSD_TEST_MODE+GSD_NOW_MS
subprocess pin cannot reach (it only fires inside realClock.now()).
Behavior-preserving: realClock.now() falls through to Date.now() whenever
GSD_TEST_MODE is unset, which is every real invocation.

* docs(#3314): amend ADR-456 with reachability-based clock-control rule

ADR-456 §(a) documented one mechanism (injected {clock=Date} +
t.mock.timers). Adds the two this repo already relies on: t.mock.timers
for in-process direct-Date reads, and the GSD_TEST_MODE+GSD_NOW_MS
subprocess pin (routed through realClock) for CLI-spawned code. Updates
TESTING-STANDARDS.md's matching passages, which already referenced this
issue by number as the no-elapsed-assertion promotion precondition.

* fix(#3314): address orthogonal review findings

Spec-axis findings: file and link the no-elapsed-assertion promotion
follow-up (#3331) instead of leaving TESTING-STANDARDS.md pointing at
a dead #1885, and ship the module-by-module audit table in the ADR
itself rather than only in a gitignored phase artifact.

Standards-axis finding: pin the "hour-old file = not active" test via
GSD_TEST_MODE+GSD_NOW_MS for consistency with the reachability rule
this PR's own ADR amendment now documents.

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

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

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

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

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

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

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

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

Verified on the remote runner.

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

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

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

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

Verified on the remote runner.

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

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

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

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

Verified on the remote runner.

* chore(#3217): backfill changeset PR number

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

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

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

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

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

Verified on the remote runner.

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

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

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

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

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

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

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

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

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

Verified on the remote runner.

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

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

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

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

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

Verified on the remote runner.

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

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

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

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

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

Verified on the remote runner.

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

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

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

* chore(#3186): backfill changeset PR number

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

693f12ad56 refactor(#3187): give state field extraction one canonical owner (#3283)
* refactor(#3187): give state field extraction one canonical owner

stateFieldValue in state-document.cts becomes the single owner of the #1760
frontmatter-then-body fallback chain. The new whole-repo guard found 14
independent re-derivations where the epic scoped 5, all now routed through it:
cmdStateSnapshot (11), cmdStatePrune (2) and smart-entry fmScalar (1).

state validate was a gate that could not fail. Every warning it could emit sat
behind a phase resolved without the frontmatter tier, so a STATE.md whose phase
lives only in frontmatter skipped the drift scan entirely and returned
valid:true. It also read unstripped content, letting a frontmatter status: key
shadow the body field (#1255 class). Both fixed; output gains a scope field so
could-not-look stops being output-identical to looked-and-clean.

Verified on the remote runner.

* docs(#3187): document the state validate scope field and its reason codes

Adds docs/how-to/interpret-state-validate-results.md so a reader can tell
nothing-to-report from could-not-look, updates the COMMANDS.md and USER-GUIDE.md
entries, corrects the CONTEXT.md glossary overstatement about Current Position
sole ownership, and drops the changeset fragment.

* fix(#3187): close three drift-guard evasion shapes and test the refuse path

The isolated adversarial review found the ladder detector was evadable by
ordinary reformatting, not just deliberately: a member or computed operand
(fm.key / fm[key]) missed the bare-identifier backreference, a swapped tier
order missed a hardcoded number-then-boolean sequence, and a ladder wrapped
across lines missed single-line detection. All three now caught, each with its
own test plus a proven boundary control.

The frontmatter-parse refuse path on the destructive complete-phase route was
unreachable and therefore untested. It is now driven by an injected parse
failure and asserts STATE.md is byte-identical after the refusal, rather than
shipping untested defensive code on a path that rewrites user state.

Verified on the remote runner.

* fix(#3187): widen the drift guard to the prompt layer and disclose tier-2 changes

The code-review spec axis found the guard's scan surface was src/ only, which is
Decision 4(d)'s forbidden allowlist one directory wide - and it had a live miss:
gsd-core/workflows/smart-entry.md tells an agent to read status from frontmatter
or the body, a prose expression of this same chain. The surface now covers the
prompt layer. That one site carries a permanent written exemption rather than a
ratchet: it is the gsd-tools-is-down fallback, so it cannot call the owner by
construction, and a ratchet would imply removable debt that does not exist.

Two tier-2 output changes shipped undisclosed and are now named in the changeset
and docs: complete-phase's idempotency guard consulting frontmatter, and the
workstream inventory resolving frontmatter-only fields. docs/COMMANDS.md gains a
state complete-phase entry, which it never had.

Also records Amendment 5 on ADR-3180, extracts the duplicated frontmatter-parse
block the epic's own thesis forbids, and re-points two assertions from free-form
warning prose onto the structured drift object.

Verified on the remote runner.

cf6de5e1c0 feat(#2871): resolve triggers and host precedence, not just placement (#3291)
* test(#2871): failing-first suite for trigger-surface resolution

23 tests over the 50-test-matrix rows. RED by construction:
resolveTriggerSurface and DEFAULT_TRIGGER_PRECEDENCE do not exist yet,
and the validator silently ignores triggerPrecedence today.

Written in the per-runtime describe idiom the other four
runtime-artifact-layout suites use, not a table.

The rows that carry the weight: windsurf must NOT report a shadow it
does not have, since its global scope emits only agents and agents are
not trigger-bearing; agents and kimi-agents must be absent from the
output for every runtime; and reordering a runtime's triggerPrecedence
must flip the winner, which is the only assertion that proves the axis
is read rather than decorative.

Stems are injected, never scanned, so the surface is assertable with no
filesystem.

* feat(#2871): resolve triggers and host precedence, not just placement

resolveTriggerSurface(runtime, scopes) returns every /gsd-<name> trigger
a runtime emits, with the scope and kind that produced it, whether the
host registers it directly or only through a router, and which artifact
shadows it. resolveRuntimeArtifactLayout is untouched -- its 7 callers
need placement only and the issue requires them unchanged.

AGENTS ARE NOT TRIGGER-BEARING, and ADR-2866 said they were. The
host-integration matrix models command and dispatch as separate interface
points: an agent is invoked through the Agent tool's subagent_type, not
by typing a slash trigger, and _copyStaged never applies the kind prefix
to an agents entry. So agents and kimi-agents are excluded from the
surface entirely, and this commit amends ADR-2866 with a dated
correction. #2218's conclusion is unchanged -- the collision is strictly
commands-vs-skills, and claude's local /gsd-* trigger surface is still
fully shadowed -- but the ADR implied the local agents surface was lost
too, and it is not.

That correction is what makes windsurf come out right. Its global scope
emits only agents, so it has no global trigger and its local commands
are unshadowed. Model agents as trigger-bearing and windsurf falsely
reports a full shadow.

The triggerPrecedence axis lands on all 19 descriptors as an ordered
kind list, one value with one owner, rather than a numeric rank spread
across N kind entries with nothing keeping them consistent. Validation
uses a required-with-default shape that has no precedent in this
validator -- every existing axis is hard-required -- so a third-party
capability.json omitting the field still validates, which is what
ADR-894's additive-only contract promises.

Winner resolution reads Phase 1's scope rank first, then the kind
ordering. A test reorders the axis and asserts the winner flips, since
an axis that is added, validated and never consulted would pass every
other assertion.

shadowedBy ships unread. Phase 4 (#2873) is its first consumer, per this
issue's out-of-scope note.

Verified via the remote runner.

* fix(#2871): single-source namespacedByDir and close two test gaps

Four findings from the isolated adversarial review.

The namespacedByDir rule had reached three copies -- install-engine,
surface, and the new trigger resolver -- one of which carried a
hand-written keep-in-sync comment and no assertion. That is this repo's
generative-fix-divergence class. Extracted to one exported predicate all
three now call. Verified by diverging one copy deliberately: the existing
#816 parity test failed, and passes again on revert.

The omission test was vacuous. Row 16 asserted that a descriptor without
triggerPrecedence still validates, but built its fixture from claude's
shipped descriptor -- which this PR had just added the axis to. It now
clones and deletes the key, following the shippedDescriptorWithout
pattern, and asserts both that validation passes and that the resolver
still picks the right winner from the default. The second half is what
makes it prove anything.

resolveTriggerSurface silently dropped an unrecognized scope while every
sibling in this epic throws. Two phases of one epic should not disagree
about whether an invalid scope is an error, so it now rejects through the
same shared validator; an empty scope list still returns empty rather
than throwing.

The ADR amendment had been spliced into the middle of the References
list, orphaning its last bullet. Moved to the top, after the header
block, which is where ADR-3660 and ADR-1016 both put dated amendments.
No lint checks markdown structure, so this was green while malformed.

* fix(#2871): single-source the command filename composition too

The earlier fix shared the namespacedByDir boolean but left the
filename composition around it written twice -- once in _copyStaged as
what actually gets written, once in resolveTriggerSurface as what gets
predicted. The predictor could go stale silently.

One exported helper now composes it for both. The entry.name asymmetry
that looked like it would block extraction does not: entry.name is
filtered to end in .md and stem is entry.name minus those three
characters, so the two branches are the same string by construction.

Divergence proven to fail: injecting a marker into the helper broke the
trigger-surface suite; reverting restored 25/25. The four sibling layout
suites hold at 227 unchanged.

* docs(#2871): correct the ADR timing notes that this phase makes stale

The Amended by back-links on ADR-3660 and ADR-1016 were written in
Phase 0, when the widenings they describe had not shipped. Each carried
a forward-looking clause -- "the module changes at Phase 2, not before,
until then this module resolves placement only" -- which becomes false
the moment this PR merges. ADR-2866's own Amends header and its
reciprocal-notes section carried the same tense.

All four now describe what shipped. This is a tense and status
correction on Accepted ADRs, not a change to any decision.

Worth stating because it is the failure mode this epic keeps meeting:
gen-adr-index.cjs tracks only Supersedes and Subsumes, so nothing in CI
would have caught either the missing back-link in Phase 0 or these stale
clauses now. They stay correct only because someone checks.

b901d1e06f feat(#1953): complexity-triggered refactor extension point (execute:post) (#3261)
* test(#1953): failing-first suite for the complexity-triggered refactor hook

60 behavioral cases against src/complexity-trigger.cts, which does not exist yet:
decision-point counting, the comment/literal stripping leak surface, threshold and
jump-delta boundaries at limit-1/limit/limit+1, stable-anchor baseline semantics,
and fs fault injection via mock.method. Two fast-check properties assert that
stripping never manufactures a decision point and that comments and string
literals are score-neutral.

Also registers the refactor-trigger capability manifest (inert until
refactor.trigger_enabled) and regenerates the capability registry and matrix.

Verified RED on the remote runner before any implementation exists.

* feat(#1953): complexity-triggered refactor extension point

Adds the opt-in refactor-trigger capability. After a phase executes, an
execute:post step measures per-function complexity for the files the phase
touched and writes a scoped refactor proposal when a function crosses the
configured threshold or drifts past its recorded anchor.

Design notes worth carrying:

- The signal is computed in-core (decision-point counting over comment- and
  literal-stripped source, Node builtins only) rather than via Memtrace or a
  shelled-out analyzer. The hook fires as a deterministic CLI, not an agent
  with MCP tools, and core takes no external dependencies — this is the only
  option a behavioral test can bind to. The metric sits behind a seam.
- The baseline is a stable anchor, not a rolling value: set on first
  observation, moved only on disposition. A rolling baseline makes the delta
  the single-phase change, so a function creeping +2 per phase never trips a
  delta of 5 and the jump check adds nothing over the absolute threshold.
- Strict mode records an open deviation window in the broken-windows ledger
  rather than declaring its own ship:pre gate. ship.md has no generic ship:pre
  gate dispatch — only two hardcoded branches — so a third gate of any kind
  would be declared and never evaluated.
- The gate clears on the proposal being dispositioned, never on the score
  improving. A blocking complexity number is one an executor can satisfy by
  splitting a coherent function in two.

execute-phase.md gains a generic execute:post step-dispatch contract; it
previously matched only ref.skill == "code-review", so any other step
registered there was declared and never run. The code-review branch is
unchanged.

Full rationale in ADR-1953.

Closes #1953

* fix(#1953): close git option injection and symlink escape in the refactor hook

Three findings from the isolated security review, all fixed inline.

HIGH — changedFilesSince interpolated the --since value into a revision
token placed before the -- separator. A -- only stops PATHSPEC parsing of
arguments after it; git still option-parses what comes before. So
--since '--output=/tmp/x' became --output=/tmp/x..HEAD, which git accepts
as --output=<file> and uses to redirect diff output — an arbitrary write.
Fixed with --end-of-options before the revision range plus a conservative
ref validator. The validator deliberately permits ~ ^ @ { } because those
are legitimate git REVISION syntax (HEAD~1, main@{yesterday}) as distinct
from ref-NAME syntax; --end-of-options is the actual barrier. The doc
comment asserting the trailing -- was sufficient was wrong and is corrected.

MEDIUM — resolveConfinedPath confined by string prefix only, so a symlink
committed inside the repo passed the check (its own path is under cwd) and
readFileSync then followed it outside the root. Now lstat-checks for a
regular file and skips anything else with REFACTOR_FILE_UNREADABLE, so one
bad path skips one file and the run continues.

LOW — the new execute:post dispatch contract showed the gsd_run example
before the rule requiring ref.command be validated first. That prose is
executed by an agent, so textual order is execution order. Reordered.

Refs #1953

* fix(#1953): make the analyzer able to see TypeScript at all

Found by running the shipped analyzer over its own source: it reported
functions=1 for a 940-line module with 24 function forms. A return-type
annotation or a generic parameter list made a function invisible —
`function f(a): number {}` and `function f<T>(a: T): T {}` both detected as
zero. Since gsd-core is written in .cts and the capability declares
.ts/.cts/.mts analyzable, the feature silently found nothing in this repo's
own primary language while reporting success. A safety net that reports
"all clear" because it cannot see is worse than no safety net.

All 98 tests passed over this, because every fixture was plain JS — the
exact failure the test matrix's own "assert against the shape production
uses" warning describes. Adds a TypeScript-shapes suite covering return
types (including unions, generics, object literals and type predicates),
generic parameter lists (constrained and defaulted), export/async/generator
combinations, annotated arrows, class-method modifiers, and optional/
default/rest params — plus the two traps: an overload signature has no body
and must not count, and `a < b && c > d` is a comparison, not a generic.
Detection now reports 24/37/21 functions for the three source files, which
matches a hand count exactly.

Also from review:

- The strict-mode ledger dedup identified entries by parsing a prose
  description string. That is banned by CONTRIBUTING's raw-text-matching
  rule and was a real bug: the "exactly one window per untriaged proposal"
  guarantee rested on prose matching, so rewording a description or editing
  WINDOWS.md by hand silently produced duplicates. Now matches structurally
  on kind + phase + file + line.
- A property test asserted on the stripper's output text. Reframed to
  assert the same invariant through analyzeSource's score.
- nextBaseline's `candidates` parameter has been dead since the anchor
  change; removed from the signature and all call sites.
- Extracted the duplicated require-or-degrade and capability-check
  boilerplate.
- ADR-1953's Implementation bullet still named a `refactor.ship-gate` in
  check-command-router.cts — a leftover from the design cut D6 rejects.
  That file is untouched and no such gate exists. Removed.

Refs #1953

* fix(#1953): keep execute-phase.md under its byte ceiling; un-vacuum the large-file test

Five of the seven remote-runner failures were one cause: the execute:post
dispatch contract, written out inline, grew execute-phase.md 1876 bytes
(93,400 -> 95,276) against a frozen PRE_PHASE6 ceiling of 93,600. A drift-ack
does not clear that — tests/phase6-capstone-conformance.test.cjs and
tests/fix-2285-claude-orchestration-wiring.test.cjs assert the file is
literally under the cap.

The contract now lives in gsd-core/references/loop-hook-dispatch.md, which
already claimed to be the point-agnostic dispatch reference and already
documented ref.skill and ref.agent. It gains the ref.command shape, its
in-context validation rule, the advisory-by-construction statement, and a
note that a point whose workflow hand-rolls one kind is not implementing
this contract. execute-phase.md now defers to it in one line: 145 bytes of
growth, 55 B of headroom under the cap. Better placement than the first cut
— the reference was overstating its coverage, and this makes the claim true
rather than duplicating prose next to it.

Acknowledged by appending to tests/emitted-drift-acks/2930-*.json rather
than a new 1953-*.json: two ack sources may never name the same path, and
that fragment is already the accumulating ack for this file.

Sixth and seventh failures: analyzesLargeFileWithinBounds tripped its own
vacuity guard — the fixture generated ~480 KB against a `> 500000` assert,
so the guard fired and the three assertions after it never ran. The test
has been vacuous since it was written. The matrix row specifies ~1 MB, so
N goes 8000 -> 20000 (1.17 MB, 17% margin) and the guard to > 1_000_000.
Verified by reproducing the exact body against the compiled module: 1168888
bytes, 118 ms, all four assertions hold.

Refs #1953

* fix(#1953): fold the execute:post step deferral into the existing resolve line

The remaining two failures were one test: execute-phase.md carries a SECOND,
tighter assertion than the 93,600 ceiling — `<=93400`, which is exactly its
current size. The file cannot grow by a single byte. My previous fix got it
under 93,600 but not under 93,400, so it still failed. ("H." in the report is
just the parent describe of that same test, not a separate defect.)

Rather than add a paragraph, the deferral now REPLACES the existing hook
resolution line. It read:

  Resolve active step hooks from `EXECUTE_POST_HOOKS_JSON` where
  `kind == "step"` and `ref.skill == "code-review"`.

which is the bug itself written down — only code-review was ever dispatched.
It now reads:

  Dispatch each `kind == "step"` hook per
  @gsd-core/references/loop-hook-dispatch.md. For `code-review`:

The following prose already begins "If no active code-review step hook
exists", so it reads correctly and the code-review handling is untouched.
Net effect on the file is -11 bytes: 93,400 -> 93,389, under the margin
assertion rather than merely under the ceiling.

That also removes the need for a drift-ack: the file shrank, so there is no
growth to acknowledge, and the append to the shared 2930-*.json fragment is
reverted. Leaving it would have shipped a claim of "145 bytes of growth"
that is no longer true, on a file six other issues share.

The test's own comment states the principle this ended up honoring: "the host
loop must stay small — optional-feature detail belongs in the capability
fragment, not the host workflow." Putting the dispatch contract in the
reference rather than inline is that rule, applied.

Refs #1953

* fix(#1953): keep the code-review hook literal the workflow test requires

tests/code-review.test.cjs extracts the <step name="code_review_gate"> block
and asserts it contains `ref.skill == "code-review"` verbatim. The previous
commit replaced the line carrying that literal, so the token vanished and the
test went red — a fair assertion: code-review IS the bespoke branch there and
the workflow should still name it.

Restored inside the same one-line deferral, which now reads:

  Dispatch `kind == "step"` hooks per @gsd-core/references/loop-hook-dispatch.md.
  `ref.skill == "code-review"`:

93,396 bytes — still under the `<=93400` margin assertion and 4 bytes below
the base, so the file continues to shrink rather than grow.

Because three consecutive runs were each reddened by a different assertion on
this one file, this change was verified by sweeping ALL of them at once rather
than one run at a time: every test under tests/ that reads execute-phase.md or
references/loop-hook-dispatch.md was located by resolving its path constants,
and each content/size assertion was evaluated directly against the working
tree — 22 assertions, plus two real executions (gen-section-manifest --check,
and emitted-attribution's full real-tree differential). All pass.

That sweep also confirms the earlier judgement call: the net change to
execute-phase.md is a SHRINK, and the size ratchet only gates growth, so
reverting the append to the shared 2930-*.json ack fragment was correct — an
ack would have been both unnecessary and factually wrong.

* chore(#1953): backfill changeset pr number to 3261

* docs(#1953): add the missing how-to for acting on a refactor proposal

Reference and explanation shipped (COMMANDS.md, CONFIGURATION.md,
FEATURES.md 159, ADR-1953) but the Diataxis how-to quadrant did not, and
that is the one a user reaches for. CONTRIBUTING's required-docs table is
'new command -> COMMANDS.md + FEATURES.md', so CI was green on a gap.

Enabling this feature is genuinely multi-step and no single page walked it:
turn it on, tune the threshold, understand advisory vs strict, discover
that strict needs a SECOND toggle on a DIFFERENT capability, and know what
to do when a proposal appears. The two-toggle subtlety in particular was a
footnote in a config table; here it is a section with both commands.

Follows the shape of its closest siblings, resolve-edge-coverage-findings
and resolve-prohibition-findings — both 'the loop surfaced a finding, here
is what to do with it'. Includes a reason-code table for the silent cases,
since the analyzer is deliberately quiet in six situations and a user who
expected a proposal needs to tell 'nothing to report' from 'could not look'.

Indexed from docs/README.md beside the other loop how-tos.

Docs-only: exempt from the push gate, no re-verification, pass marker on
2af188b4 untouched.

Refs #1953

* feat(#1953): warn when strict mode is on but nothing will actually block

Closes acceptance criterion 5, which I had wrongly marked satisfied.

refactor.trigger_strict records an untriaged proposal as an open deviation
window, but a ship only STOPS if workflow.windows_enforce is also on — a
toggle owned by the broken-windows capability that this feature neither sets
nor requires. So a user could enable strict, believe ship was gated, and find
out otherwise at ship time.

The split itself stays: requires:["broken-windows"] would force-install the
ledger on advisory users who never enable strict, and a ship:pre gate of our
own would never fire because ship.md has no generic ship:pre gate dispatch.
What was missing was discoverability, so that is what this fixes.

`refactor evaluate` now emits a typed REFACTOR_STRICT_NOT_ENFORCING warning,
naming the exact remediation command, whenever strict is on and either
workflow.windows_enforce is off or broken-windows is unavailable. It fires
only on a run that produced a candidate — with nothing to block on there is
nothing to warn about, and warning every run would be noise.

Reads workflow.windows_enforce through the same resolveConfigKey walk the
router already uses for its own keys rather than a second config reader.
Four tests cover the matrix: strict+enforce-off warns, strict+enforce-on does
not, strict+ledger-absent warns, strict-off never warns.

Also corrects a user-facing message in this same file that told the user to
run `gsd-tools config-set` — the wrong form. docs/CONFIGURATION.md and the
broken-windows capability both use `gsd config-set`, and gsd-tools is invoked
as `node gsd-tools.cjs`, so the bare form may not resolve. The two adjacent
messages in this file now agree.

653f95e39f chore(#2801): remove the hostBehaviors.reviewerCli deprecated alias (#3272)
* test(#2801): failing-first suite for the hostBehaviors.reviewerCli alias removal

Inverts the Phase 5a rows that assert the derived legacy alias still
contributes a reviewer slug, and adds the removal-warning coverage the
alias's exit needs (ADR-2782 D9).

RED against unmodified production code, by design: the six shipped
manifests still declare the key and collectReviewerWarnings emits nothing
for hostBehaviors.

Refs #2801

* chore(#2801): remove the hostBehaviors.reviewerCli deprecated alias

ADR-2782 D9, Phase 7 — the final phase of epic #2782.

The derived legacy alias survived one release (Phase 5a shipped in 1.9.0;
1.9.1 and 1.10.0 have since gone out), so it goes. A declared reviewer
body is now the only route onto the reviewer roster.

- deriveReviewerSlugs no longer reads runtime.hostBehaviors.reviewerCli
- the key is stripped from the six manifests that carried it; each already
  declares a reviewer body whose slug equals its capability id, so the
  derived roster is unchanged at the same twelve slugs
- collectReviewerWarnings emits a presence-based, non-fatal removal notice
  for any manifest still declaring the key, reaching both the build-time
  registry generation and the third-party overlay load path. The check runs
  before the reviewer-body early-return, because the manifest it exists for
  is the alias-only one that has no body.
- hostBehaviors stays an open, unvalidated bag for its other 59 keys; this
  adds one keyed removal notice, not general validation

Refs #2801

* refactor(#2801): give the reviewer-warning channel a typed IR

Review finding: the new tests asserted with String#includes() on the
warning prose, which CONTRIBUTING.md's 'Prohibited: Raw Text Matching on
Test Outputs' bans in favor of a typed intermediate representation.

Adds the IR beside the renderer rather than replacing it, which is the
shape that section prescribes and bin/verify-reapply-patches.cjs already
models:

- REVIEWER_WARNING, a frozen code enum
- REMOVED_REVIEWER_CLI_FIELD, so the emitting site and its test share one
  symbol instead of duplicating a literal
- collectReviewerWarningRecords(cap), returning typed records

collectReviewerWarnings(cap) keeps its exact string[] contract as a thin
map over the records, so both production consumers are untouched. Every
section-K row now asserts on record.code/field/capId and none on the
rendered message. Locks the code surface, asserts the renderer stays
one-to-one with the records, and migrates the pre-existing Phase 2 test
on the same channel off prose matching.

Refs #2801

* test(#2801): invert the section F alias fall-through regression row

Caught by the remote runner: 2 unique failures on both Node lanes out of
31,692. tests/reviewer-lane-declarations.test.cjs section F — Phase 5a's
isolated-security-review regressions — asserted that a blank reviewer.slug
falls through to the hostBehaviors.reviewerCli alias rather than dropping
the lane. That is the direct inverse of this phase's contract.

The original rationale held only while the alias existed. With it gone
there is nothing to fall through to: a blank body is not a declaration,
and a declaration is the only route onto the roster.

Inverted rather than deleted — the row carries the adversarial-review
provenance for the slug trim, and removing a security regression guard to
make a change pass is backwards. The duplicate row added earlier in
section C is dropped instead; section F is its canonical home.

Also corrects two count strings Phase 5b left at eleven while asserting
twelve, which would misreport on failure.

Refs #2801

* docs(#2801): give the removed reviewerCli flag a migration path

The Reference edit alone satisfied CI — a file under docs/ moved, so
lint-docs-required.cjs was green — while the task-oriented quadrant said
nothing about the removal. A maintainer whose lane had just gone silent
would have found the field documented as removed and no page telling them
what to do about it.

Adds a migration section to the how-to: the symptom, the verbatim warning
they will see, the before/after manifest, and the note to keep the
reviewer slug equal to the capability id so existing
review.default_reviewers entries and --<slug> flags survive.

Refs #2801

* chore(#2801): backfill changeset pr number to 3272

* feat(#2801): close the runtime.hostBehaviors vocabulary

ADR-1016 closes twelve descriptor axes and rejects an open escape hatch
in the descriptor. It never mentioned runtime.hostBehaviors, and that
silence was read as permission: 59 keys across 18 manifests, 39 of them
set by a single capability, validated by nothing. The reference docs went
further and attributed the open seam to ADR-1016, which does not mention
the field at all.

KNOWN_HOST_BEHAVIORS enumerates the vocabulary. An undeclared key yields a
non-fatal UNKNOWN_HOST_BEHAVIOR record on the same D4.3 channel as the
alias removal notice, reaching both build-time generation and overlay
install.

Warning, never error, for the reason this phase exists: an error would
hard-break an out-of-tree descriptor carrying a bespoke key with no
deprecation window, which is what reviewerCli was given a release to
avoid. Escalation is a separate decision.

reviewerCli is excluded from the unknown-key sweep so it keeps its own
notice with the migration pointer rather than drawing two records.

A parity test binds the vocabulary to the shipped manifests in both
directions, and a second asserts no shipped capability draws a notice, so
the closure is provably inert in-tree.

Records the decision and the miscitation as an ADR-1016 amendment.

Refs #2801

* fix(#2801): bound and sanitize the unknown-key diagnostics

Two findings from an isolated adversarial review of the closure commit,
both proven by execution rather than asserted.

MAJOR, introduced by the closure: the new Object.keys(hostBehaviors) sweep
had no ceiling. An installed third-party manifest is bounded only by
MANIFEST_MAX_BYTES, and an 8.69MB manifest with 800,000 keys produced
800,000 records and ~139MB of message text, retained for the registry's
lifetime in OverlayMeta.diagnostics. Now capped at ten records plus a
summary carrying omittedCount, mirroring capability-loader's existing
slice(0,3) idiom. The same manifest now yields 11 records and 1748 chars.

MINOR, newly reachable: manifest-supplied key names were interpolated raw.
Unlike cap.id, which validateCapability gates on KEBAB_RE before these
diagnostics run, hostBehaviors keys have no grammar check anywhere, so
ANSI escapes and CRLF reached stderr and OverlayMeta.warnings intact. New
describeKey replaces C0/C1 controls and clips at 80 chars. The file
already had describeValue for this and applied it only to values.

Both fixes land on the pre-existing reviewer.* sweep too — it carried the
identical pair, and fixing only the new copy would leave the same defect
one screen from its own fix.
