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

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

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

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

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

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

* chore(#3875): regenerate CONTEXT-INDEX.json for the glossary entry

lint:generated-sync failed on CI: gen-context-index.cjs derives
docs/CONTEXT-INDEX.json from CONTEXT.md, and the RULESET.EMITTED_ATTRIBUTION

* chore(#3875): regenerate the example CONTEXT-INDEX for the glossary entry

CONTEXT.md feeds TWO committed indexes, not one: docs/CONTEXT-INDEX.json via

regenerated only the first, so the parity check stayed red.

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

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

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

Refs #3871

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

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

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

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

Refs #3871

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

Review of the first two commits found four things.

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

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

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

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

Refs #3871

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

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

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

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

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

Refs #3871

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Fourth review round.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Round seven, plus one thing I found myself.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

86fa2917d7 enh(#3866): dispatch step and contribution hooks at verify:pre (#3869)
* test(#3866): pin that verify:pre must dispatch every hook kind

verify-work.md's verify_pre_hooks step dispatches only `kind == "gate"`, so
getWiredKinds reports verify:pre -> {gate} and gen-capability-registry rejects
any capability declaring a step or contribution there. The verify lane is
therefore closed to capabilities that want to contribute to what UAT covers
rather than refuse to let it start.

Failing-first: the step, contribution, and exact-kind-set rows are RED; the
pre-existing gate row is a green regression pin so the new arms cannot orphan
the arm verify:pre already had.

Refs #3866

* feat(#3866): dispatch step and contribution hooks at verify:pre

verify_pre_hooks dispatched `kind == "gate"` only, so getWiredKinds reported
verify:pre -> {gate} and gen-capability-registry's validateHooksWired rejected
any capability declaring a step or contribution there. A capability could
refuse to let UAT start; it could not contribute to what UAT covers.

Add contribution and step arms mirroring execute:wave:post, deferring to
references/loop-hook-dispatch.md and carrying its ref.command in-context
validation guard ahead of any shell-use prose. A verify:pre step is advisory:
it never blocks the start of UAT and an erroring step is routed by its own
onError. The gate arm and its check guard are untouched.

Give extract_tests an additive consumption seam for the artefacts those steps
declare via the existing steps[].produces field -- no new registry field, no
new ordering, no invented filename. Manifest-supplied artefact names are
validated in-context against an allowlist and resolved only inside PHASE_DIR.
With no producing step the derivation is unchanged, pinned by test rather than
asserted in prose.

Review findings folded in: the artefact-name allowlist (isolated adversarial
pass), the artefact-shape contract and the seam-inertness tests (spec axis),
and the reference/how-to split so one constraint has one source of truth
(standards axis).

7bbbe495d7 docs(#3473): ADR-3473 — enforcement by construction, one owner per invariant (Phase 0) (#3870)
Phase 0 of epic #3473 ships this ADR alone. Every rule in §8 carries a
status of Enforced or Required — Phase N.

§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
ADR-3180 and ADR-3408 left between them: the write seam's unvalidated
input, its classification-excluded reporting, and the schema transcribed
by hand into nine artifacts.

Derivation authority is explicitly NOT in scope here — it lands as
ADR-3180 Amendment 8, generalizing §7.5's already-locked sentence.

fb2d122d7f feat(#3841): assert gsd-tools identity on every state-mutating verb (#3848)
* feat(#3841): assert gsd-tools identity before any state-mutating verb

only this package publishes. The path-based branches — a project-local install,
a runtime config directory — had no such guarantee; they trusted their
configured location. This closes them.

Mechanism: once resolution finishes, and before any verb runs, the preamble
probes the tool it picked with `runtime-identity --raw` and matches the answer
with a shell `case` pattern ANCHORED to the start of the compact payload
(`{"packageName":"@opengsd/gsd-core"`). An unanchored substring match accepts
the decoy `{"packageName":"get-shit-done-cc","note":"@opengsd/gsd-core"}`, which
any colliding package could publish. The outcome is exported as the two-valued
`GSD_IDENTITY_STATUS` (`ok`/`unverified`), so the gate is asserted on a VALUE
rather than on warning prose. Rollout is warn-then-fail per the #3146 ruling:
`unverified` prints one line naming BOTH causes and continues, because
`no_identity_verb` cannot tell a foreign package from an `@opengsd/gsd-core`
older than the verb, and at rollout the old-version case is the common one.

The blocker was byte budget, not design. The preamble is inlined into 112
shipped files and several sat within single-digit bytes of frozen ceilings
(`gsd-verifier.md` 16 bytes, `gsd-executor.md` 33, `execute-phase.md` 234); a
first attempt broke five of them. What made room was collapsing the resolver's
twenty near-identical `elif [ -f … ]` arms into one candidate-list helper
(`_gsd_at`), which buys far more than the assertion costs. The preamble is now
2,624 bytes against 4,500 — a net 1,876 bytes SMALLER per inlined file, so every
capped file moved away from its ceiling rather than toward it. No cap raised, no
size-budget exception added, no override token emitted.

Resolution order, every runtime-home probe, the `unset -f gsd_run` re-source
fix, the fail-closed `exit 1`, and the `CLAUDE_ENV_FILE` persistence are all
preserved byte-for-byte in substring terms; the snippet still begins with
`_GSD_SHIM_NAME=` and still ends with `fi`, which the parity extractors anchor
on. `gsd-core/references/gsd-run-resolver.md` is re-synced byte-equal.

Also fixes two stale claims found in passing: CONTEXT.md and FEATURES.md both
described an `[ -x ]` guard as the load-bearing re-source defense. That guard
was tried and REMOVED in #3831 — it rejected the bare function name, fell
through every branch, and hit `exit 1`, which kills a sourced caller's shell.
`unset -f gsd_run` is the actual mechanism.

* fix(#3841): pair the anchor's brace by requiring a closed identity payload

The matrix went red on `tests/new-project-mvp-prompt.test.cjs` — "new-project.md
has unbalanced braces: net depth 2" — plus a knock-on report from its parent
`bug #1516` describe, which is the same failure counted once at the child and
once at the block.

Root cause: that guard (:182-189, mirroring #3784 bd53925f) walks characters and
increments on `{`, decrements on `}`, with no awareness of shell quoting. It
scans `new-project.md` PLUS every `new-project/steps/*.md`, and both
`new-project.md` and `steps/auto-mode-config.md` carry one inlined preamble copy
— hence net 2 from a snippet that was off by exactly one. The unpaired brace was
the `{` inside the single-quoted `case` pattern of the identity anchor, which is
correct shell and invisible to a text scanner.

Fix in the snippet, not the guard. The pattern now anchors at BOTH ends:
`'{"packageName":"@opengsd/gsd-core"'*'}'`. That balances 51/51 with a brace that
does real work rather than a cosmetic pair — a truncated payload whose prefix
matches now fails too, where before it verified. Safe for any future additive
field: a JSON object's own closing brace is always the last character, whatever
type the last value has, which is pinned by two negative-space tests (a nested
object and an array-valued last key must both still verify). Cost: +3 bytes,
against the 1,873 the resolver fold already gave back.

The alternative considered and rejected was dropping the literal `{` for a `?`
glob. It balances too, but weakens the anchor from "must be an opening brace" to
"must be any one character", and the anchor is the entire point.

Two guards added so this cannot recur silently:
- runtime-launcher-parity (F0) pins brace balance at the SNIPPET, so the next
  edit to that pattern fails on the file it broke instead of surfacing three
  files downstream in a test whose name mentions neither the launcher nor this
  issue. It also asserts depth never goes negative, since a `}` preceding its
  `{` nets to zero while being unbalanced at every prefix.
- runtime-identity gains behavioral truncated-payload and trailing-garbage
  fixtures, so the added `}` is proven load-bearing rather than merely present.

Verified: snippet 51/51 braces; new-project combined net depth 0; the seven
other preamble-bearing files with nonzero depth are unchanged from merged next
(their own prose, not the preamble, and not in any guard's scan set); all 112
inlined copies and the resolver reference re-synced byte-equal; sync:launcher
idempotent on the second run.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Closes #3146

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refs #3691

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

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

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

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

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

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

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

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

Fixes #3691

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

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

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

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

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

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

Refs #3691

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

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

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

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

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

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

Refs #3685

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

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

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

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

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

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

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

c933184b97 enhance(#3172): require a stated failing direction for every automated acceptance command (#3825)
* test(#3172): failing-first suite for the stated failing-direction probe

Pins the <fails_when> pairing walk, placeholder denylist, MISSING sentinel
exemption, degraded-read contract, CLI arm and the plan-authoring contract text.
RED by construction: the module exports it requires do not exist yet.
Executed on the remote runner.

* feat(#3172): require a stated failing direction for every automated acceptance command

Every runnable <automated> command now carries a <fails_when> sibling naming
what output constitutes failure. A command with no expressible failure mode is
not an acceptance test: it reads as rigour and is not falsifiable.

- verify-command-grounding gains a failing-direction probe sharing the existing
  <automated> grammar, MISSING sentinel and walk guard rather than copying them
- gsd-tools check verify-failure-directions <N> backs it; plan-phase dispatches
  it and hands the JSON to gsd-plan-checker check 8f
- Dimension 8 detail extracted to references to stay under the agent size cap

Verified on the remote runner.

* fix(#3172): close four review findings in the failing-direction probe

- MISSING_SENTINEL_RE matched an env-var assignment prefix (MISSING=1 cmd), so
  a real command was exempted from the new blocking gate. Tightened the SHARED
  constant rather than adding a second copy.
- Both token regexes scanned to EOF on unclosed openers (O(n^2), 1562ms at 40k).
  Bodies are now non-crossing; 1ms, byte-identical on well-formed input. The
  pre-existing AUTOMATED_BLOCK_RE carried the same defect and is fixed here too.
- probePhaseFailingDirections reported status 'ok' when one plan was unreadable,
  conflating 'could not look' with 'nothing to report'.
- Extracted the phase-resolution block both check arms had copied verbatim.

Also corrects a docs/AGENTS.md dimension list stale since #2401.
Verified on the remote runner.

* fix(#3172): project the planner rule onto the spawn contract, settle emitted bookkeeping

The remote runner refuted the planner-side edit. agents/gsd-planner.md is frozen
under a 49152-LF-char cap asserted by four suites and sat at 49,146 — six chars
of headroom — so the +537 of authoring rule blew it. #3297/#3645 already settled
where such a rule goes: the planner spawn contract in plan-phase.md, beside
<tracked_source_paths>. The agent file is reverted to origin/next verbatim.

- plan-phase.md gains <failing_direction_contract>; tests row 30 now asserts the
  contract there and row 30b guards the freeze in both directions
- plan-phase.md growth acknowledged by APPENDING to the 3409 fragment, per the
  precedent that two ack sources may never name the same path
- install-tree fixtures regenerated for the three new reference files

Verified on the remote runner.

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

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

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

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

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

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

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

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

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

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

a2387a0545 feat(#3034): add opt-in parallel reviewer lanes (#3822)
* test(#3034): failing-first coverage for opt-in parallel reviewer lanes

Executes the real invoke_reviewers dispatch block from review.md against a
stubbed gsd_run seam rather than pattern-matching the workflow text, so the
two properties that actually carry risk are observable: that every lane is
joined before aggregation, and that concurrent lanes cannot tear a line in
gsd-review-lane-results.jsonl.

Concurrency is proven by a barrier fixture, not by elapsed time -- each stub
lane blocks until all lanes have checked in, which can only complete if they
overlap.

Red against the current sequential dispatch, by design.

Refs #3034

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

* feat(#3034): add opt-in parallel reviewer lanes

Reviewer lanes within one review pass inspect the same immutable plan
snapshot and have no dependency on one another, but were dispatched strictly
one at a time, so a multi-reviewer pass cost roughly the sum of its lanes.
The serialization is a deliberate protection against provider rate limits,
so it stays the default; review.parallel_lanes opts a project out of it.

The loop body is hoisted into run_review_lane so the sequential and
concurrent paths share one body -- two hand-synced dispatch bodies is the
divergence class ADR-2782 spent a phase deleting. Each lane writes a
slug-scoped result file, concatenated in selection order after the join:
concurrent O_APPEND is atomic only below PIPE_BUF, and write_reviews parses
that JSONL to render the models:/model_sources: frontmatter, so a torn line
is a broken REVIEWS.md rather than a cosmetic log defect. Aggregating in
selection order also keeps the artifact byte-identical between the two paths.

The guard is strict equality on "true" and falls back to sequential when
config-get fails -- the opposite polarity from the commit_docs guard,
because failing open here fires the very requests the default prevents.

Also corrects docs/COMMANDS.md and its four locale mirrors, which described
--all as running every configured reviewer in parallel when dispatch was in
fact sequential.

Closes #3034

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

* fix(#3034): de-duplicate dispatch slugs and scope lane locals

Review finding (Standards axis): a slug repeated in SELECTED_REVIEWERS would
put two concurrent background jobs on the same > -truncated per-lane result
file. The shared-append form this replaced could not corrupt itself that way,
so de-duplicating is what keeps the concurrent path no worse than the
sequential one.

Selection de-dupes today -- the roster is a Set and review.default_reviewers
normalizes lowercase-unique -- but reachability analysis is not a contract,
which is the same reason the roster derivation itself is guarded.

Splitting once into DISPATCH_SLUGS also removes the duplicated tr-split the
same review flagged: the dispatch and aggregation loops now share one list,
which is what guarantees they walk the same slugs in the same order. A plain
string accumulator rather than an array, because zsh and bash disagree on
array indexing and this block runs under both.

Also scopes run_review_lane's locals. Not a live fix -- each dispatched call
already forks its own subshell -- but it makes the isolation a property of the
function rather than of the dispatch mechanism happening to fork.

* test(#3034): acknowledge review.md growth, drop spent 2295 ack

The differential attribution gate reported review.md growing 4173 bytes
(30712 -> 34885) with no live acknowledgment. Adds the per-PR fragment it
asks for, naming only the one path it reported.

Deleting tests/emitted-drift-acks/2295-resolved-model.json is required, not
opportunistic. That fragment declared review.md and nothing else, and its
ripple is already absorbed into the base, so it is spent -- it can no longer
clear anything, which is why the gate still reported review.md as
unacknowledged. It could not simply be left alone either: two ack sources may
never name the same path, so it blocked this PR's fragment outright.
CONTRIBUTING is explicit that a fragment whose last entry is removed gets
deleted with it, because an empty fragment signals nothing while its presence
reads as a live alarm.

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

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

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

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

Closes #3078

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

Three review findings, all fixed:

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

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

Refs #3078

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

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

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

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

Refs #3078

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

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

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

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

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

Refs #3078

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

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

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

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

cf15682d1c enhance(#3028): responsive Markdown separators instead of fixed-width rules (#3789)
* feat(#3028): responsive Markdown separators instead of fixed-width rules

Stage banners, checkpoints, completion and error panels used fixed-width
runs of box-drawing characters -- a 53-column heavy rule and a 62-column
double-line box. Those runs are ordinary text to a Markdown-rendering
host, so in a narrower pane they wrap and the border comes apart from
the heading it framed.

Shipped content now emits an ATX heading for a titled section and a
blank-line-delimited --- for a break between sections, both of which
adapt to the available width. The same convention is applied to the
three code sites that built these strings at runtime: the UAT
checkpoint renderer, the milestone-close audit report, and the TDD
review checkpoint table.

Removing the box also removes its only reason to exist -- the
east-asian-width padding helpers that kept its right border aligned
(checkpointBoxLine, displayWidth, isWideCodePoint, ZERO_WIDTH_MARK_RE,
CHECKPOINT_BOX_WIDTH). RTL directional isolation is unchanged.

The convention is specified in gsd-core/references/ui-brand.md and
enforced across all shipped content by tests/responsive-separators.test.cjs.

Refs #3028

* test(#3028): pin the heading form in checkpoint and audit-report assertions

These suites asserted the exact box borders and the 62-column padded
banner interior. With the box gone they assert the ### heading form,
the --- break and the bolded instruction line, and each now carries a
positive assertion that no box character remains -- which is what pins
the fix rather than merely tolerating it.

Language coverage is converted, not dropped: Japanese, Chinese, Korean,
Hindi and Arabic all still assert their rendered banner, and the Arabic
case still asserts the RTL directional isolates the box removal must
not disturb. Adds a case for a banner longer than the old inner width,
which previously produced a ragged border and now has none.

Refs #3028

* chore(#3028): acknowledge execute-plan.md growth from the checkpoint display spec

The checkpoint_protocol display spec described the drawn box; it now
describes the heading, the --- break and the bolded action prompt,
which costs 22 bytes (40111 -> 40133, 827 under the cap).

Appended to the existing #3370 fragment rather than filed as a new one:
a growth ack keys on the bare filename and #3370 already declares
execute-plan.md, so a second source naming it would be a hard
duplicate-key error. Same supersede-by-append route #3370 took for the
spent #2652 fragment.

Refs #3028

* docs(#3028): state the load-bearing half of the separator rule, and amend the zh-CN reference

Review found three things.

The rule as first written demanded a blank line above AND below every
---. Only the one above is load-bearing: it is what stops CommonMark
reading the rule as a setext underline for the line above. The one below
is cosmetic, because a thematic break is a leaf block. The rule now says
that, with the reason, instead of asserting a stricter form the content
does not keep.

The zh-CN reference had received the mechanical box-to-heading swap but
none of the prose behind it: it still claimed a 62-character checkpoint
width and still listed --- among forbidden mixed banner styles, so it
contradicted the convention it was translating. It now carries the
separator section, the setext reasoning, the unconditional-vs-per-runtime
rationale and a corrected anti-pattern list, in Chinese.

The user guide asserted that a heading is not a degradation anywhere.
That is an assertion, not a demonstration. It now says what was actually
traded away in a plain terminal, points at the recorded rationale, and
invites the report that would justify the capability flag instead.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

622f43353c fix(#3299): tracer feedback gate honors workflow.human_verify_mode (#3390)
* fix(#3299): tracer feedback gate honors workflow.human_verify_mode

The tracer feedback gate (#2294) predates `workflow.human_verify_mode`
(#3309, whose scope was the planner and verifier only), and branched on
auto-mode alone. Under the documented `end-of-phase` default an
interactive run therefore halted after EVERY `type="tracer"` task,
synthesizing a `checkpoint:human-verify` no planner ever emitted and
asking the user to retype a verdict the executor had just computed —
at the cost of a full executor cold-start each time.

Planner-side suppression cannot reach this halt because the executor
synthesizes it at runtime, which is why #3309 did not close it.

The gate now branches on HUMAN_VERIFY_MODE in the interactive path:
under `end-of-phase` an automated-only tracer `<verify>` is re-run and,
on success, expansion continues with no checkpoint. HALT-on-failure is
unchanged. `mid-flight`, `gate="blocking-human"`, and tracers carrying
genuine `<human-check>` evidence all still stop; the autonomous branch
is untouched.

`--default end-of-phase` on the config read is load-bearing, not
decorative: `workflow.human_verify_mode` is absent from SCHEMA_DEFAULTS,
so a bare `config-get` exits non-zero with `Key not found` on any
project whose config.json predates #3309 — which is the reporter's
exact config and every pre-existing project.

Both copies of the rule (workflows/execute-plan.md and
agents/gsd-executor.md) are updated together; the reference doc records
the seam and the human-check-still-halts rationale so it cannot recur.

Fixes #3299

* fix(#3299): reconcile the canonical schema table and the stale acceptance test

Review round 1 (trek-e) — three items, all in the drift class this PR is
about, two of them landed inside this PR's own diff.

1. docs/reference/plan-md.md:233 — CONTEXT.md names this file the canonical
   schema reference for the tracer task-type contract, and its Task-types row
   still claimed interactive runs unconditionally present a
   checkpoint:human-verify. CONTEXT.md and docs/AGENTS.md were updated in the
   first round; this one was missed, so the authoritative reference was the
   wrong answer. The row now carries the human_verify_mode-conditional
   behavior and points at the canonical precedence chain.

2. tests/tracer-bullet.test.cjs — the docs assertion only checked that a
   tracer ROW EXISTS, never its content, which is why CI could not see the
   drift. It now asserts the row's actual claims and rejects the pre-#3299
   wording. Separately, the #1945 acceptance test named 'interactive run emits
   checkpoint:human-verify after the tracer' kept passing only because its
   substrings still occur in the fallback clause, while its name asserted the
   opposite of shipped behavior. Renamed and narrowed to what #1945 still
   guarantees, plus a new interactiveIsConditional pin so the unconditional
   prose cannot be restored under a passing substring check.

3. plan-md.md's <verify> row now documents that the legacy bare-text form
   (valid, and still shown at :179) does not reach the #3299 auto-continue —
   only a <verify> carrying <automated> does — so the benefit is silently
   unreachable for tracers using that format.

Mutation-verified: reverting the plan-md row fails 1 test; reverting the
executor's interactive branch fails 4.

* fix(#3299): make the tracer gate reachable from the planner template, and bind the assertions

Peer review round 3 found two Majors, both verified by reproducing the
mutation before fixing.

MAJOR 1 — the fix was largely inert on its own default path.
agents/gsd-planner.md's Nyquist Rule (:191) says every <verify> includes
<automated>, but the tracer-specific template twelve lines later emitted the
legacy bare-text form. The gate auto-continues only on a <verify> carrying
only <automated>, so every tracer produced from the canonical template fell
to the STOP fallback and #3299's benefit was unreachable for exactly the task
type it targets. Template now wraps in <automated>; a contract assertion pins
it so the two cannot drift apart again.

MAJOR 2 — the new assertions did not bind condition to action.
Appending 'Nevertheless, interactive runs always present a
checkpoint:human-verify' to the canonical row, and 'then immediately STOP and
return a checkpoint:human-verify' to the auto-continue clause in BOTH
operative copies, restored unconditional interactive checkpointing and left
the suite 35/35 green. Every required keyword still matched. Fixed by:

- clause 2 must now contain no STOP outcome and emit no checkpoint at all —
  'never a checkpoint' has to be true OF the clause, not merely stated in it;
- interactiveIsConditional replaced with the ordered-clause parse plus the
  same no-STOP property, instead of proving only that HUMAN_VERIFY_MODE
  appears somewhere on the line;
- the plan-md.md Autonomy cell is now pinned EXACTLY rather than by keyword
  presence. Deliberately brittle: CONTEXT.md names that table the canonical
  schema reference, so a wording change must be a conscious edit in both
  places.

Mutation-verified after the fix: the combined semantic regression now fails 3
tests; reverting the planner template fails 1.

* test(#3299): exact-pin the safety clauses instead of blacklisting outcome verbs

Peer review round 4. Blacklisting did not hold, twice over:

- Round 3 banned literal STOP and the 'return a'/'present a' checkpoint
  forms in the auto-continue clause. Round 4 defeated that by appending
  'then pause and invoke checkpoint_protocol with a checkpoint:human-verify
  before expansion' — none of the banned tokens, same restored interruption
  after every successful tracer. 36/36 passed.
- The planner guard looked for <automated> anywhere inside <verify>, so
  '<verify>[...]<!--<automated>--></verify>' satisfied it while leaving the
  legacy bare form operative. 107/107 passed across tracer, planner and the
  three size-cap suites.

Synonyms are unbounded; the clauses are not. Both are now pinned exactly on
normalized whitespace, the same approach already proven on the plan-md.md
Autonomy cell, with defence-in-depth checks behind them: no checkpoint-emitting
or blocking outcome in any wording inside clause 2, and the planner's <verify>
body must be exactly one non-empty <automated> child with no commented markup.

These pins are deliberately brittle. Each is a safety contract, so changing the
behavior must be a conscious edit in both the prose and the expectation.

Mutation-verified: the synonym-checkpoint mutation fails 1; the commented-out
wrapper fails 1; the round-3 literal-STOP + contradictory-doc-row regression
fails 3.

* test(#3299): strip comments, require uniqueness, pin whole regions

Peer review round 5. Exact-pinning one clause was still bypassable two ways,
both reproduced before fixing (each left the suite fully green):

- COMMENTED DECOYS. Put the correct text in an HTML comment followed by a live
  wrong copy: every extractor selected the commented decoy. Worked against the
  planner template, the canonical plan-md.md row, and both executor branches.
- SURROUNDING OVERRIDE. Insert 'after every tracer, pause and invoke
  checkpoint_protocol before expansion, regardless of the mode-specific rules
  below' immediately ABOVE the pinned clause, or 'ignore row 3; always wait for
  approval' below the canonical table. The pinned text was untouched, so
  equality held while the shipped meaning inverted.

The shape that holds, applied to every operative surface:
  1. strip HTML comments BEFORE selecting, so a decoy cannot be chosen;
  2. require the structural anchor to occur EXACTLY ONCE, so a live second copy
     cannot hide behind a correct first one;
  3. pin the ENTIRE decision region, not one clause, so no unparsed prefix or
     suffix can override what the pin proves.

Applied to: the executor's whole tracer branch, execute-plan.md's whole
dispatch line, checkpoints.md's whole precedence section, and plan-md.md's
Autonomy cell.

Also addresses the round-5 Minor: the planner template is now asserted
STRUCTURALLY (exactly one <verify> in the fenced block, body exactly one
non-empty <automated> child) rather than pinning the descriptive placeholder
verbatim, so behavior-preserving wording changes no longer false-fail. The
clause and section pins keep their exact form — those have a safety rationale
the placeholder copy does not.

Mutation-verified, all six rounds: override-above-clause 1; commented decoy row
1; commented decoy branch 1; ignore-row-3 override 1; synonym checkpoint 1;
commented-out wrapper 2.

* test(#3299): drop the superseded exact-placeholder planner assertion

Peer review round 6, Minor. The round-5 brittleness fix ADDED a structural
planner assertion but left the old exact-placeholder one in place, so the
over-brittleness it was meant to remove was still live: rewording the
descriptive placeholder while preserving exactly one non-empty direct
<automated> child failed the old test and passed the new one.

Removed the old test. The structural assertion is the real contract — the gate
auto-continues on the SHAPE of the verify, not on the wording of a placeholder.

Verified both directions: a behavior-preserving reword now passes; reverting the
template to bare <verify> still fails.

* test(#3299): select operative prose via parsePredicates, not a hand-rolled scanner

Peer review round 7. I had judged the round-6 selector bypass adversarial-only
and out of scope, intending to disclose it. Both premises were wrong, and the
review said so:

- 'Needs new src API' — false. parsePredicates is ALREADY a public export and
  internally uses the repo's interleaved fence/comment scanner. Instrumenting
  candidate lines as throwaway predicate declarations borrows that scanner with
  no src change at all.
- 'Adversarial-only' — false, and this is the part that mattered. Two ORDINARY
  edits silently turned the guards into decoy checks:
    * a forgotten '-->' comments the live rule through to EOF, and the
      balanced-only stripper still saw and accepted the commented rule;
    * a normal fenced documentation example of the rule, plus a whitespace-only
      reformat of the live list item, made the selector choose the example.
  Neither needs intent. A dangling comment is a typo; a fenced example is good
  documentation. Together they reproduce exactly the accidental drift #3299 came
  from — with CI green.

The selection layer now defers to parsePredicates for operativeness, uses
whitespace-tolerant anchors so a reformat cannot decouple the live line from its
pin, extracts regions by operative line index rather than string search, and
carries a self-guard test proving fenced / balanced-commented /
after-unclosed-comment copies are all excluded. The helper also ignores indexes
it did not inject, so a pre-existing GSDTEST.CANDIDATE line cannot pollute it.

Verified both ordinary-edit scenarios now fail the suite (each was green before).

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* test(#3299): close the operative-selection gaps the maintainer blocked on

trek-e's Blocker: the operative-line selection layer had three gaps, all
reachable by ordinary future doc edits rather than sabotage. He independently
found a fourth I had not disclosed. All are fixed.

1. INDENTATION PROMOTION (his find, not in my disclosure). The instrumentation
   replaced a matched candidate with an UNINDENTED marker regardless of the
   original line's indentation. A 4-space-indented CommonMark code block is not
   skipped by parsePredicates (it accepts indented declarations by design), so
   stripping the indent PROMOTED an indented decoy to operative — the exact
   inversion of the guard's purpose. The marker now preserves the original
   indent, and a candidate that is itself indented 4+ spaces is never injected.

2. NO SET MEMBERSHIP. The filter accepted any in-range integer, so a
   pre-existing literal GSDTEST.CANDIDATE=<valid index> in source text could
   pollute the count. Now filters on a Set of the indexes actually injected on
   this call.

3. RAW FENCE SELECTION (planner). The template test matched the first raw
   ```xml fence after the marker with no fence/comment awareness — the one
   selection in the suite that was not operative-aware — so a commented-out
   decoy template between the marker and the real one would be selected while
   the live template regressed. The opener must now be operative AND the first
   non-blank line after the marker.

4. RAW END ANCHOR (regionFrom). The end anchor was tested against raw lines, so
   a fenced example containing a ### / <type line truncated the pinned region
   early — a false FAILURE on a legitimate doc edit. End anchors now go through
   the same operative filter as start anchors.

Mutation-verified: the indented-decoy + whitespace-varied-anchor combination
and the commented-out fence decoy each now fail the suite (both passed clean
before). Truncation is confirmed fixed by extraction — the region spans the
full section and retains the content following a fenced example, where it
previously stopped at it.

Note on the remaining brittleness: adding a fenced example INSIDE a pinned
region still fails the whole-region exact pin. That is the intended tradeoff
for a safety contract, not the truncation defect, and is called out as such.

* test(#3299): allow-list operative indentation; pin marker provenance

Review round 9.

BLOCKER — the round-8 indentation guard was written as a DENY-list,
/^(?: {4,}|\t)/, and CommonMark has more indented-code forms than that
enumerates: " \t", "  \t" and "   \t" all open an indented code block and all
slipped through, so an indented decoy was still promoted to operative while the
live rule regressed (34/34 green). Inverted to an allow-list — only 0-3 literal
spaces is ordinary block indentation; anything else is code. Enumerating the
bad shapes was the error, not the specific regex.

MINOR — the injected-index Set validated the marker's VALUE but not its SOURCE.
A pre-existing literal `GSDTEST.CANDIDATE=<n>` could name an index that some
other (skipped) candidate had contributed to the set, and be accepted. Now also
requires p.line - 1 === Number(p.value): the predicate must have been parsed
from the line it names.

MINOR (false negative) — ```xml title=x is a valid CommonMark info string, and
requiring exactly ```xml failed the suite (33/34) on a behavior-preserving edit.
Both the opener assertion and the extraction now accept an info string.

Mutation-verified: the mixed " \t" decoy and the forged-provenance marker each
now fail; the info-string fence no longer false-fails.

KNOWN LIMITATION, disclosed on the PR rather than papered over: parsePredicates
is a predicate parser, not a general CommonMark operativeness oracle. Two
standards-valid constructs still read as operative — a lazy blockquote
continuation line (state opens only on a line that literally starts with ">"),
and a comment opened mid-line ("prose <!--", where state opens only when the
trimmed line STARTS with "<!--"). Closing those means either teaching the shared
src/context-predicates.cts about container/lazy-continuation state — a change to
a module every health rule consumes, well outside a tracer-gate fix — or
hand-rolling a CommonMark parser inside a test, which is how this suite got into
trouble in the first place. Left for the maintainer to scope.

* chore(#3299): re-arm the execute-plan.md emitted-drift ack after the base merge

The #3299 ack rode on tests/emitted-drift-acks/2652-quick-diagnose-dispatch-isolation.json,
which upstream retired in 362d0434b (#3370) once #2728's entries were spent.
#3370's own fragment now owns execute-plan.md at the base, so a new
3299-*.json naming that path would collide — mergeAckSources rejects a
duplicate key across fragments rather than silently last-winning.

Re-arms #3370's entry instead, the mechanism the gate is built for (a spent
ack whose reason changes in the diff is live again), carrying #3370's own
reason forward verbatim so the base growth keeps its account.

Verified: emitted-attribution 175/175 against origin/next@be9329b10.

* fix(#3299): honor golden rule 6 in the tracer gate, extract the chain

Addresses the review on #3390 (B1-B3, M1-M4, minors).

B3 — checkpoints.md asserted two incompatible rules about the same gate.
Golden rule 6 says gate="blocking-human" stops for a human in every mode;
the precedence table scoped row 1 to interactive runs, so a first-match
chain let an auto-mode tracer carrying that gate fall to row 2 and
auto-continue. Rule 6 wins: row 1 is now "Any run, any mode", the
justification sentence it falsified is gone, and the STOP is evaluated
before the auto-mode branch at all three dispatch sites — gsd-executor.md,
execute-plan.md and the plan-md.md schema row. Unreachable by our planner
is not unreachable: src/verify.cts parses only `type` and never consults
`gate` on non-checkpoint tasks, so an imported PLAN.md can carry it.

B1 — the LARGE-tier cap. gsd-executor.md is 49150 on next against a 49152
cap, so this PR could not add a byte. Extracted rather than trimmed: the
precedence chain now lives only in checkpoints.md (already @-imported by
<checkpoint_protocol>, so no new load), and the duplicate summary inside
that protocol section is a pointer. The rationale the earlier trim
deleted is restored — "production-quality, never a throwaway" and
"Pouring more layers onto a broken foundation...". Result 49097: 55 bytes
under the cap and a net 53-byte REDUCTION against next, so the PR returns
headroom instead of consuming it.

B2 — merged upstream/next and resolved all three drift-ack conflicts.
2775 changed shape upstream (string -> {reason}); adopted the new form.

M1 — the 2775 ack claimed the Nyquist Rule sat "twelve lines earlier"; it
is ~75 lines. Corrected to "earlier in the file".
M2 — ack arithmetic restated from measurement, not from a stale base. The
2943 #3299 append is DELETED: with gsd-executor.md now shrinking there is
no ripple to acknowledge, and emitted-attribution correctly flagged the
entry as stale.
M3 — changeset rewritten to the documented bold-lead + em-dash one-liner.
M4 — the two self-defeated shapes are gone. The planner-human-verify-mode
presence checks now go through operativeLineIndexes. The config-get check
does NOT: all three reads live inside ```bash fences, which is their
correct executable form, and that selector excludes fenced lines by
design. It instead pins exactly one live, uncommented, fenced read per
file — mutation-tested against both a commented-out read and a duplicate.

Minors — dangling colon lead-in dropped, a "below" pointer that pointed
above corrected, and the `(default)` asymmetry between the two dispatch
copies aligned.

Two defects the merge surfaced, both caught only by the full suite:
the new #3576 gate rejected this PR's own bare `references/checkpoints.md`
cite in planner-human-verify-mode.md (rewritten to the canonical
gsd-core/ form), and the line-keyed PROSE_ALLOWLIST entry for
gsd-executor.md needed 794 -> 795 after this change shifted the line.

* fix(#3299): correct the size record the 08-22 merge falsified

Review round: one Major, four Minors.

Major — the #3299 arm's arithmetic was measured before the merge and is
now wrong in a document whose whole purpose is to be an accurate size
record. Re-measured at head: execute-plan.md is 39315 B on next and
40111 B here, so the 796-byte delta was right but the endpoints and the
headroom were not (849 bytes against DEFAULT_CAP 40960, not 1003). The
superseded figures are named rather than silently replaced. Confirmed
the workflow cap counts LF BYTES while the agent cap counts CHARACTERS —
two caps in two units, one per file.

Minor 1 — 2943-context7-tool-name.json reverted to next. JSON.parse of
both sides was already identical; the diff was an em-dash/times-sign
re-serialization left over from adding and then removing the #3299 arm.
No business in this PR.

Minor 2 — the duplicated `tracer row Autonomy cell` test is gone. Both
copies were new here and carried the same ~8-line canonical string; the
one removed selected its row with a raw startsWith find, the shape this
suite records at :477 as defeated in round 1. Its rationale — why the
cell is pinned EXACTLY, and the append-a-contradiction attack that
defeated keyword matching — is carried onto the surviving fence-aware
copy rather than deleted with it.

Minor 3 — the executor's condensed interactive clause said only "re-run,
continue", which does not distinguish pass from fail; read in isolation
it invites expansion onto a broken slice, the outcome the gate exists to
prevent. Now "re-run; fails → HALT as above, passes → continue, no
checkpoint". The pinned expected string moved with it. Executor at
48,905 chars, 247 under the cap.

Minor 4 — 2775 asserted two different current sizes for gsd-planner.md.
The stale half is next's own text taken wholesale, so the contradiction
was inherited; it now reads as a before-figure rather than a current one.

* fix(#3299): cite the plan-md example by section, not by a drifting line

Review round 7, Nit N-1. The 2775 ack fragment justified its one-line
formatting with "matching docs/reference/plan-md.md:207's own example
style". At head, :207 is prose; the one-line <verify><automated>
example it means is at :222. The citation was accurate when written
(77c2fda, f23205c) and drifted with a later merge of next.

Re-pointed by section rather than by line — it has already drifted
once, and the fragment's whole purpose is to be an accurate record —
and the drift itself is recorded inline so the correction does not
quietly overwrite what the earlier number said.

Also narrows the changeset's "any task with gate=blocking-human" to
"any tracer carrying gate=blocking-human" (found by Codex in the
whole-PR pass). Golden rule 6 and the #3299 decision table both scope
that gate to checkpoints and to the tracer feedback gate; the normal
type="auto" branch never inspects `gate`, so the wider claim promised
behavior the implementation does not have.

* fix(#3299): answer fence-delimiter liveness by insertion, not replacement

Review round 9. The round-8 fence-awareness fix was itself unsound, in the same
class it was added to close.

`operativeLineIndexes` detects operative lines by REPLACING each candidate with
a throwaway predicate declaration and asking `parsePredicates` which survived.
Sound for ordinary content lines. Not sound for a fence DELIMITER, which is
exactly what the tracer-template selection passed it: deleting every ```xml
OPENER leaves each matching closer to become an opener, and since
`computeSkippedLineFlags` is a strict FORWARD state machine, fence parity
inverts for the whole remainder of the document.

Measured against the real file rather than argued:

  agents/gsd-planner.md has 3 live top-level ```xml openers — 0-based 180, 232,
  262. operativeLineIndexes reported 180 and 262. Line 232, the "Task-level TDD"
  example, read NON-OPERATIVE — a wrong answer from a helper whose only job is
  that question.

It passed only by parity coincidence, and one extra live example anywhere
earlier flipped it to a false FAILURE blaming a decoy that does not exist:

  HEAD as-is                  | anchor 260 | openIdx 262 | ASSERTION PASSES
  +1 unrelated ```xml example | anchor 265 | openIdx 267 | ASSERTION *** FAILS ***

Fixed by asking the question a way that perturbs nothing. `isOperativePosition`
INSERTS a marker on its own line immediately before the candidate instead of
replacing it. Insertion preserves every delimiter, and because the skip-state
machine runs strictly forward, a line inserted at `idx` observes exactly the
fence/comment state the candidate observes, with nothing but the marker between
them — so marker-operative IS the candidate's position-liveness.

The review's suggested direction (substitute a same-shaped opener that still
opens a fence) cannot work here: the marker would then be inside the fence and
would never parse as a predicate at all.

Position-liveness is not content-liveness, so the helper also rejects a line
that is entirely comment (`<!-- ```xml -->`), rather than leaving that to each
caller's own shape test to happen to exclude.

`operativeLineIndexes` now THROWS when its candidate regex matches a fence
delimiter, so the unsound route cannot be reached again by a future caller
rather than only being fixed at the one site that got it wrong.

Verified with the same extra-example scenario above: with the fix, all 35 rows
stay green. Teeth: reverting the call site to `operativeLineSet` turns the
tracer-template row red on the new guard. The regression row pins both live
openers (the second is the one the deletion route lost), the block-commented
and same-line-commented openers, a line inside a fence, and re-checks both
openers after unrelated lines shift above them.

Only tests/tracer-bullet.test.cjs changes — no agent file is touched, so the
5-char gsd-planner.md and 19-byte gsd-executor.md headroom are unaffected.

Verified: `npm run lint:ci` exit 0; full `npm test` 31307 tests / 31292 pass /
0 fail / 14 skipped, TMPDIR unset, against a freshly synced origin/next.

* fix(#3299): guard the delimiter class, match the scanner, pin the assignment

Codex full-PR review of #3390, run against the round-9 head. Three defects,
two of them in the code that round added.

1. The mode-read pin survived the regression it exists to catch.
   `READ` matched the config-get substring only, so rewriting the shipped line
   as `IGNORED_MODE=$(gsd_run query config-get ...)` kept the row green while
   nothing defined HUMAN_VERIFY_MODE — the gate falls through to STOP and #3299
   is back with the suite passing. The regex now requires the assignment. A
   lookahead after `end-of-phase` closes the other half: the bare prefix also
   accepted `--default end-of-phase-wrong`. Proven by mutation: renaming the
   variable in agents/gsd-executor.md now turns that row red, and did not before.

2. The round-9 fence-delimiter guard was a SAMPLE of the class, not the class.
   It probed a fixed list of five delimiter strings. `~~~xml`, ```json, `~~~~`
   and arbitrary info strings all walk past any list short enough to write down
   — the guard was added precisely because one such regex had already slipped
   through. Now matched against the lines the regex actually selects in the
   document, which cannot go stale and cannot miss a spelling nobody thought of.
   Four such spellings pinned as rows.

3. `isOperativePosition` disagreed with the scanner it delegates to.
   For `<!-- closed --> real content` it stripped the span, found surviving
   content, and answered "live". `computeSkippedLineFlags` skips an ENTIRE line
   whose trimmed text starts with `<!--`, balanced or not, before it considers
   fences at all. Verified directly against parsePredicates. It now applies the
   scanner's own rule instead of out-reasoning it. Latent for the present caller
   (its anchored ```xml shape cannot match a comment-prefixed line), real in
   general.

Disclosed rather than fixed, and raised with the maintainer: the exact executor
region pin ends before the second operative tracer-gate paragraph at
agents/gsd-executor.md:327, which is only heading-checked — so contradictory
later instructions could ship. How much of that file to pin is a call for its
owner.

Independently probed isOperativePosition across 19 edge cases before the review
(line 0, CRLF, tab / 4-space / mixed " \t" indentation, 0-3 space fences, nested
fences, ~~~ fences, info strings, bounds); all correct. That probe is what
surfaced finding 2, which the review then confirmed from the other direction.

Verified: `npm run lint:ci` exit 0; full `npm test` 31296 tests / 31281 pass /
0 fail / 14 skipped, TMPDIR unset. One caveat stated rather than smoothed over:
in that run tests/planning-snapshot.test.cjs was truncated by concurrency after
row A5 — 11 tests did not execute, which a 0-fail aggregate cannot show. Re-run
in isolation it is 87 tests / 87 pass / 0 fail, and it is untouched by this
change.

a44d513566 fix(#3712): confine in-process installs to a sandboxed HOME (#3725)
* fix(#3712): confine in-process installs to a sandboxed HOME

A runtime kind may declare a global `home` override resolved from os.homedir()
rather than from the caller's configDir — codex's skills kind (`home: ".agents"`,
ADR-1239 / #2088) is the only live case. Sandboxing configDir/targetDir does not
contain it, and assertDestWithinConfigHome cannot see the class: that gate
confines a destSubpath to whatever root it is handed, and here the root IS the
escaped home. So an in-process caller that forgot to sandbox HOME wrote to, and
pruned gsd-* entries from, the developer's REAL ~/.agents/skills.

tests/agent-descriptor-parity.install.test.cjs's K1 loop did exactly that: it
iterates every agents-kind runtime (codex included) with a sandboxed targetDir
and an un-sandboxed HOME. Reproduced against a canary home on next @ adb46cdd8 —
71 gsd-* skill dirs deleted, a foreign `cloudflare` skill surviving, suite still
exit 0. It is silent because the runtime's own config home is untouched, so the
manifest keeps reporting a healthy install.

FIVE writers resolve a kind `home` and then destroy under it. Three are reachable
today — installRuntimeArtifacts, uninstallRuntimeArtifacts (install-engine.cts)
and applySurface (surface.cts). Two are descriptor-dependent and guarded against a
future descriptor change rather than a present escape: installOpencodeFamilySkills
(behind the combined-family early return) and installAgentsKindStandalone. Those
two are scoped to the single kind each destroys — passing the whole layout made
codex's unrelated skills override trip a writer that never touches it.

- src/test-home-guard.cts: refuse when a run under a test runner cannot be shown
  to have sandboxed HOME. NODE_TEST_CONTEXT (set by `node --test`) gates it, so
  installs outside a Node test context are untouched; GSD_TEST_MODE is unusable,
  as several candidate files including the offender never set it. Homes are
  compared by FILESYSTEM IDENTITY (st_dev + st_ino), not by pathname:
  path.resolve() resolves neither symlinks nor case, and realpath returns a
  canonical pathname that two routes to one directory can still disagree on (bind
  mounts). Verified on macOS/APFS — HOME=/users/<name> made the strings differ
  while naming the same directory, and the lexical form ALLOWED a write into the
  physical real home. FAILS CLOSED: a pair is "different" only when both identify,
  or one is definitively absent (ENOENT/ENOTDIR) while the other identifies; every
  other errno is "cannot tell" and refuses. Only when neither home identifies is a
  marker consulted, and it carries the sandbox PATH and must equal the home in
  effect — a boolean checked first let an ambient or stale value disarm the guard.
- helpers: promote sandboxHome() out of its two byte-identical private copies,
  which is also what makes them record the sandbox; the three withFakeHome()
  helpers record it too. The marker NAME is duplicated as a bare string rather
  than required from the compiled guard, keeping helpers.cjs's documented
  no-built-lib-at-import-time contract; a test pins the two together.
- agent-descriptor-parity: sandbox HOME across the K1 loop.
- helpers-process-isolation: #3156's canary asserts on <home>/.gsd only, and its
  `--cursor --local` spawn cannot reach `.agents` at all, so an assertion added
  there would pass with all confinement removed. Add a discriminating row — a
  `--codex --global` spawn against a seeded ambient home — which also asserts the
  runtime still declares the override. Its check is a sampled inventory (dir names
  + each SKILL.md), not a tree compare.
- install-write-confinement: predicate rows through the deps seam, covering the
  symlinked HOME, ambient and stale markers, and each sameDirectory branch
  (both-identify, one-absent, neither-identifiable), plus wiring rows that drive
  the REAL entrypoints so deleting a guard call site is red.

Verified: guard fires end-to-end against a real un-sandboxed HOME (exit 1, zero
deletions); the case-variant fail-open reproduced on APFS before the fix and
refuses after; K1 file 29/29 green with skills intact; mutation-tested — each of
the three reachable call sites, lexical-only comparison, and treating an unknown
errno as "absent" each take exactly one row red, with every mutation echoed back;
the process-isolation row negative-controlled by reverting installerEnv to its
pre-#3156 leak (16/0 -> 13/3); a full npm test leaves ~/.agents/skills at 71.

Stated residual: the two descriptor-dependent writers have no wiring test, because
no runtime declares a `home` override on those kinds and neither can be exercised
without inventing a descriptor.

* chore(#3712): add changeset

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

* fix(#3712): let a sandbox nested inside the real home through the guard

All six Windows shards of #3725 failed on legitimately sandboxed
destinations. On Windows os.tmpdir() is %LOCALAPPDATA%\Temp — inside the
user's home — so every sandbox a test creates is a descendant of the real
home, and "does this land inside the real home?" answers yes for the safe
case and the dangerous one alike. POSIX conceals this: /tmp and
/var/folders both sit outside $HOME.

Add the missing conjunct: a destination inside the real home is allowed
only when it also sits beneath a HOME that was sandboxed away from the
passwd home. Both halves are required — dropping the first re-admits a
plain un-sandboxed install, and dropping the second decays into the
"is HOME sandboxed?" check the module rejects, which a layout resolved
before the sandbox walks straight through. Each is mutation-proven by a
row that goes red without it.

Also covers the two fail-closed branches of the new exemption, which
survived mutation to `true` with the suite green, and avoids `<user>` in
a docblock — the prompt-injection scanner reads it as a delimiter tag.

* fix(#3712): close three writer/rollback gaps found reviewing the whole PR

Cross-AI review of the full PR (not just the round's delta) surfaced
three ways the guard could still be defeated:

- The nested-sandbox exemption trusted the SPELLING of a destination.
  With HOME sandboxed to a directory inside the real home — legitimate on
  Windows — an aliased `.agents` (symlink, junction, subordinate bind
  mount) beneath it redirected an allowed path into the real home. Decide
  containment on the path the write RESOLVES to: walk up to the nearest
  existing ancestor, canonicalize, re-append the tail.

- `migrateLegacyDevPreferencesToSkill` is a SIXTH writer that resolves a
  skills-kind `home` override. It creates rather than prunes, which is
  why it was missed, and `_runLegacyInstallMigrations` runs it before
  `installRuntimeArtifacts`' own assertion. Guarded, scoped to that kind.

- Worst of the three: `bin/install.js` snapshots the resolved skills root
  before installing, and its outer catch rolls back by deleting and
  recreating every snapshotted `gsd-*` directory there. The guard's own
  throw landed in that catch, so refusing an un-sandboxed codex install
  provoked exactly the mutation the guard exists to prevent. Refusals are
  now marked and rethrown without rollback — nothing was written, so
  there is no partial install to undo. Every other error still rolls back.

Also carries the sandbox marker into `installSpawnEnv`, so spawned
installers are not refused on passwd-less CI images, and corrects three
claims that no longer hold: "every writer" (six, and named), the
unconditional "fails CLOSED" (the passwd-less marker branch is a
deliberate weakening, and TOCTOU is out of scope), and the assertion that
Windows os.tmpdir() is always %LOCALAPPDATA%\Temp (Node honors TEMP/TMP).

* docs(#3712): name the guard's two limits instead of overclaiming

Round-2 review found the prose had drifted ahead of the code. Corrected,
with no behavior change:

- The module still said FIVE writers; there are six, and the sixth is
  now named along with why it was missed (it creates rather than prunes)
  and why it carries its own assertion (it runs before the main one).
- The canonicalization docblock listed subordinate bind mounts among the
  aliases it closes. It does not close them: a bind mount is not a link,
  so realpath keeps the mount-point spelling. `sameDirectory` already
  recorded that limit; the new helper now inherits it explicitly rather
  than contradicting it. Closing it needs mount-table introspection.
- "FAILS CLOSED" was unqualified while the passwd-less marker branch is
  a deliberate weakening — with no passwd entry, nothing can contradict a
  marker naming the real home.
- "Refuses BEFORE any write" was too broad: legacy install migrations run
  ahead of the layout-driven ones, which is exactly why the two
  rollbackInstallerMigrations() calls still execute before the rethrow.
  Only the codex skills-root rollback is skipped, and that is the only
  _codexPreConfigRollback() call site — applySurface is never called from
  bin/install.js and uninstall cannot reach it.

* fix(#3712): sandbox HOME in the opencode-family home-override parity rows

The last two Windows failures, and the same platform asymmetry in a
different disguise. This row drives a skills-kind `home` override on
purpose — precisely what the guard polices — but relied on the override
temp dir happening to sit outside the real home. It does on POSIX
(/tmp, /var/folders); on Windows os.tmpdir() is under %USERPROFILE%, so
the guard correctly refused and only Windows went red.

Declare the sandbox instead of depending on the platform: HOME becomes
the override itself, which is the home the call writes under. This is the
fix the guard's own message prescribes, applied to the test rather than
to the guard.

Both failing Windows shards fail on exactly these two rows and nothing
else; every other shard is green.

* fix(#3712): make sameDirectory answer NO when it cannot tell

Review Major 1. sameDirectory()'s only caller is the passwd-less marker
branch, which reads a `true` as permission to PROCEED:

    if (marker && sameDirectory(marker, osMod.homedir())) return;

The fallthrough returned `true` whenever neither side identified — two
absent paths, or two stats failing EACCES/EPERM/EIO on a locked-down
host — on the reasoning that "cannot tell" should make the caller refuse.
That reasoning was inverted with respect to this caller: it turned the
passwd-less escape hatch into an unconditional bypass for any marker
value at all, on precisely the hosts the fallback exists to serve. Only
two things now answer yes: one resolved pathname, or two readable
identities that match. Restoring the old fallthrough takes the new row
red.

Also from review:

- Major 2 asked whether st_dev/st_ino discriminate directories on
  Windows, where Node derives them from BY_HANDLE_FILE_INFORMATION. The
  whole guard rests on that primitive, so assert it rather than argue it:
  a row comparing two distinct temp directories, and one directory
  reached by two spellings. It runs on every platform in the matrix, so
  Windows answers the question itself.

- Minor 1: the refusal now names the real home it compared against, not
  just the destination it refused. That is the one fact needed to tell a
  true positive from a false one, and its absence is what made the
  Windows case a CI-log dig rather than a glance.

* fix(#3712): refuse a HOME that merely spells the real home more widely

Review round: one Blocker, four Minors, a Nit.

N2 (the one with teeth) — a destination's ancestor chain is linear, so
"inside the real home AND inside the effective HOME" admits two
arrangements, not one. The intended `effectiveHome ⊂ realHome` is the
Windows temp shape; `realHome ⊂ effectiveHome` — HOME at /Users, /home,
C:\Users — is not a sandbox at all, it is the real home reached by a
wider spelling, and it was exempting a stale destination pointing
straight at ~/.agents. Third conjunct added; the docblock no longer
claims two conditions suffice. Removing the conjunct reds the new row
and nothing else.

N4 — the migration guard resolved its OWN layout, and without
capabilityRegistry, so a registry-dependent descriptor could make it
vouch for a path the migration does not write: a guard reporting safe
while the unsafe write proceeds. It now guards the destination already
resolved by _resolveDevPreferencesSkillTarget, keyed on
`installRoot !== targetDir` — which is exactly the condition under which
a `home` override was declared, read off that same result.

N1 — CONTEXT.md gains the Test Home Guard Module glossary entry that
contributor-standards.md requires of a new Module. Not CI-enforced, so
green CI was never evidence it was met.

N3 — the docs/INVENTORY.md row was misfiled between install-fs-adapter
and install-model-override-resolver; the table is alphabetical and the
manifest already had it right. Moved, and its text now names six writers
and the third conjunct.

N5 — applySurface's signature docblock was two parameters stale; this PR
added the second of them.

N6 — the duplicated rollbackInstallerMigrations() adjacent to the new
rethrow: two identical consecutive calls, not two phases.

* fix(#3712): guard the sixth writer, and close two false-ALLOW paths

Review round 3 (NEW-1, NEW-2) plus three defects Codex found in the
whole-PR pass, each reproduced before it was fixed.

NEW-1 — migrateLegacyDevPreferencesToSkill called the guard with no
`deps`, so it bound real os/process.env and could not be wiring-tested
the way the other three reachable writers were. It now takes the same
optional `deps: { os?, env? }` tail parameter. The wiring block gains
the missing fourth row, and a fifth pinning the ALLOW half; the test
file's header docblock said "FIVE writers ... the three reachable
today", contradicting the six/four statement this PR already put in
src/test-home-guard.cts, CONTEXT.md, docs/INVENTORY.md and the
changeset. Both directions of the guard's condition now fail a row
when broken — previously neither did.

NEW-2 — derivesFromSandboxedHome's docblock claimed "THREE conditions
are required, and no two of them suffice". False for {2,3}: isInside is
reflexive, so whenever conjunct 1 fires conjunct 2 already returns
false on its own. Reworded as a fast path, which is what it is.

Codex 1 (false ALLOW) — on a host with no readable passwd entry the
marker branch returned as soon as the marker matched the effective
HOME. That attests a caller sandboxed HOME and says nothing about where
an already-resolved destination points, so a layout captured before
sandboxHome() — still naming the real ~/.agents — was waved straight
through: the same stale-layout shape the primary branch refuses by
design. The marker must now identify AND contain every destination.

Codex 2 (false ALLOW) — `installRoot !== targetDir` was the stand-in
for "the skills kind declared a home override". The two are not
equivalent: the inequality is false when the override resolves onto
targetDir itself, which is exactly a configDir of $HOME/.agents. The
guard was skipped and SKILL.md written into the real home under a test
runner. _resolveDevPreferencesSkillTarget now reports hasHomeOverride
off the same resolution instead of inferring it from two paths.

Codex 3 (prose) — the shared refusal message claimed every guarded
writer prunes; the migrate writer only creates. The changeset headline
claimed in-process installer calls can no longer reach the real home,
which is wider than the guard: writeNonClaudeDefaults still writes
~/.gsd/defaults.json through os.homedir(). INVENTORY's and CONTEXT's
fail-closed sentences omitted sameDirectory's pathname-equality
shortcut. All four narrowed to what the code does.

* fix(#3712): let the sandbox marker follow an overridden HOME

Found by Codex in the whole-PR pass. installSpawnEnv spreads
`overrides` last so an explicit HOME wins — deliberate, and its
docblock tells callers needing per-spawn isolation to pass their own
{ HOME, USERPROFILE }. But the #3712 marker was set before that spread,
so such a caller got HOME=<theirs> and marker=<helper default>. On a
host with no readable passwd entry the guard compares the two and
refuses a legitimately sandboxed spawn — tests/install.test.cjs:7143
and install-shared.cjs's own runInstaller both take that path.

The marker is now derived from the final HOME unless the caller
supplied one explicitly. The contract test asserted HOME after an
override but not the marker, which is why it stayed green.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

* docs(#3712): name the shipped guard condition, not the deleted one

Review round 4 of #3725. Two artifacts this PR adds still described
`target.installRoot !== targetDir` in the PRESENT tense as the live guard
condition on `migrateLegacyDevPreferencesToSkill`. The shipped condition is
`runtime && target.hasHomeOverride` (src/install-engine.cts:510).

This is not ordinary doc drift. The named condition is the exact false-ALLOW
the previous round closed: a `home` override resolving onto `targetDir` — a
configDir of `$HOME/.agents`, which is where codex's override points — makes
the inequality FALSE while the override is declared, so the guard was skipped.
A maintainer reading CONTEXT.md:290 as authoritative would believe the guard
still skips that case.

  - tests/install-write-confinement.test.cjs — the ALLOW-half row's comment.
    Its "teeth" rationale is unchanged and still correct as written.
  - CONTEXT.md:290 — the Test Home Guard Module glossary entry, a documented
    PR gate. Now states the condition and names the inequality only as what it
    is NOT, with the reason.

The three surviving mentions of the inequality are all past-tense or negated
(src/install-engine.cts:448, :508 and the sibling test comment at :3698) and
are correct as they stand.

Verified: `npm run lint:ci` exit 0; full `npm test` 31327 tests / 31312 pass /
0 fail / 14 skipped, run with TMPDIR unset.

* fix(#3712): canonicalization fails closed, matching identify's errno split

Codex full-PR review of #3725, run against the round-4 head.

`resolveThroughLinks` caught EVERY realpathSync error and fell back to
`path.resolve(dest)` — the lexical spelling. That inverts the function's own
purpose. An aliased `<sandbox>/.agents` that cannot be canonicalized keeps its
sandbox spelling, satisfies the nested-sandbox exemption at :227, and the write
is ALLOWED into the real home — the exact escape this walk exists to close. The
module documents that it fails CLOSED with ONE named exception (the marker
branch); this was a second, unnamed one.

Split by errno, and deliberately by the SAME split `identify` already draws
rather than a second policy in one module — both answer "does this path exist
as named?", so they must not disagree:

  ENOENT / ENOTDIR -> walk up. The ordinary case: a fresh install resolves a
    destination nothing has created yet, so realpath fails on the leaf and on
    every not-yet-created ancestor. Refusing here rejects every install.
  anything else (EACCES, EPERM, ELOOP, EIO) -> refuse. The component exists but
    cannot be resolved, so the guard cannot tell where the write lands.

Three rows in the predicate block, beside the other aliasing rows:
  - a symlink CYCLE in the destination path (ELOOP)   -> REFUSE
  - a destination that does not exist yet (ENOENT)    -> ALLOW
  - a component behind a regular file (ENOTDIR)       -> ALLOW

Teeth checked against the artifact the test loads, not the source: reverting
the condition to the swallow-everything shape in the compiled
test-home-guard.cjs turns row 1 — and only row 1 — red. The ENOTDIR row caught
a stale build during development, which is the point of asserting on the
compiled file.

CONTEXT.md and the resolveThroughLinks docblock both record the new behaviour,
so this does not repeat the prose-vs-code drift the round-4 finding was about.

The changeset's existing scope sentence now bounds "six writers" to the
`installRuntimeArtifacts` call tree and names `cmdGenerateDevPreferences` —
which resolves the same codex `home` override through `getGlobalSkillsBase` and
writes SKILL.md beneath it unguarded. It has no in-process caller today (its
only direct require-and-call is a spawnSync with HOME sandboxed), so it is
latent rather than live, and whether it belongs in this PR is raised with the
maintainer rather than decided here.

Verified: `npm run lint:ci` exit 0; full `npm test` 31330 tests / 31315 pass /
0 fail / 14 skipped, TMPDIR unset.

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.

b6977d9d11 fix(#3762): enforce docs/INVENTORY.md roster rows, backfill 32 gaps (#3766)
* test(#3762): failing-first roster gate for docs/INVENTORY.md rows

Anchors the human half of the inventory-drift rule: every entry in
docs/INVENTORY-MANIFEST.json must have a hand-written row in
docs/INVENTORY.md. Expected RED on this commit -- next carries 32
unrostered surfaces, which is the defect the gate exists to catch.

* fix(#3762): enforce docs/INVENTORY.md roster rows, backfill 32 gaps

docs/INVENTORY.md calls itself the authoritative roster of every shipped
GSD surface, and CLAUDE.md's inventory-drift rule requires both a roster
row and a manifest regen. Only the manifest half was anchored, so a PR
could ship a surface, regenerate the manifest, omit the row, and stay
green -- as PR #3758 did with gsd-core/references/planner-coupling.md.

Adds the roster half to tests/inventory-manifest-sync.test.cjs, backed by
a pure matcher in tests/helpers/inventory-roster.cjs, and backfills the 32
surfaces already missing rows on next.

Fixes #3762

* test(#3762): harden roster matcher against fenced blocks and trim exports

Skips fenced code regions when splitting level-2 sections so a documented
'## ' example inside a fence cannot truncate a family section (false red)
or contribute a phantom row (false pass); makes the heading pattern linear
rather than a backtracking lazy match; narrows the module surface to the
three names the gate consumes.

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

* fix(#3762): close two false-RED gaps found in orthogonal review

Indented headings: CommonMark permits an ATX heading to carry 1-3 leading
spaces, and a ^##-anchored pattern read such a document as having no family
sections at all -- reporting all six missing, a structural red for zero real
drift. Reproduced, then fixed and pinned.

Link-wrapped cells: a row written as [`x.md`](../x.md) was not recognized,
though docs/INVENTORY.md already uses that form elsewhere. Unwrapping now
peels a whole-cell link and a whole-cell code span, and only layers that
wrap the cell entirely -- a file mentioned mid-prose is still not a row, so
the false red is not traded for a false pass.

Adds a second fast-check property over the commands source-link rule, the
one family whose matching rule differs from the other five.

* chore: remove stray pwned_cmdsub injection-test canary from the repo root

A zero-byte file committed by 0e6fa2e2c (#3124) while remediating the
#3118 command-substitution injection — the marker a test wrote into cwd to
prove a substitution had NOT executed, left behind when the run ended.
Nothing in the tree references it (verified by Grep across the repo),
package.json's files array excludes root-level files so it never shipped,
and lint-removed-but-needed confirms no surviving reference.

Found while auditing the repo root for #3762; fixed inline rather than
deferred, per CLAUDE.md's no-deferrals rule.

2f86278b5e fix(#3003): opt-in mechanism for intentional deletions in worktree.cleanup-wave (#3757)
* test(#3003): failing-first suite for declared deletions in cleanup-wave

Binds the guard's opt-in before it exists, so the suite is RED against next.

The rows that carry the weight are the over-authorization set: a directory
declaration must not authorize its children, a glob declaration must authorize
nothing, and a declaration must not act as a string prefix of another path.
Each of those BLOCKS, and each would PASS under a prefix, glob, or startsWith
matcher — which is how a path list quietly degrades into the boolean opt-in
#3003 explicitly rejected. The glob row matters most: declaredScopePrefix
already returns null ("matches everything") for a glob-leading pattern, correct
for the advisory it serves and catastrophic for a gate.

Also pinned: a failed deletion check blocks on its own reason rather than being
filtered into a pass; the block detail names only the undeclared residue so the
operator is not misdirected by paths that were fine; an entry with no
declaration blocks exactly as before; junk and non-array declarations do not
authorize; and a blocked entry still isolates rather than aborting the wave
(#2852, which must stay fixed).

Two advisory rows cover an interaction found while designing: git diff
--name-only includes deleted paths, so without unioning the declaration into
the #2596 scope check, authorizing a deletion would raise
SCOPE_OUT_OF_DECLARED against the very path just authorized.

A seeded property states the whole invariant the three over-authorization rows
sample: a deletion merges iff its normalized path is in the declared set.

* feat(#3003): declared deletions opt-in for the cleanup-wave guard

The deletions guard blocked the merge-back of any executor branch whose diff
removed a file, with no way to say a removal was intended. A plan that folded
one test file into a sibling could not be merged by the tool meant to merge it,
forcing a manual --no-ff outside the tool -- strictly less safe than what the
guard protects against.

A plan now declares removals in its own frontmatter (files_deleted), and that
list rides the same path files_modified already travels: plan-document parse ->
phase plan JSON -> the per-plan worktree gate -> record-agent/create
--deletions -> declared_deletions on the manifest entry -> the guard. The guard
blocks only the deletions NOT in that list.

A path list rather than a boolean, per the pinned decision: a boolean disarms
the guard for the whole entry, so an unexpected deletion riding along with a
declared one would pass unnoticed. Matching is exact after the module's shared
normalizer -- never a prefix, never a glob. Both would let one declaration
authorize a whole set, which is the mass-deletion accident the guard exists to
catch. That also means declaredScopePrefix is deliberately NOT reused here: it
returns null ("matches everything") for a glob-leading pattern, which is right
for the advisory it serves and would silently disarm a gate.

The block detail now carries only the undeclared residue, so an operator is not
sent looking at paths that were fine. A failed deletion check still blocks on
its own reason and is never filtered into a pass. A blocked entry still
isolates rather than aborting the wave (#2852).

The #2596 scope advisory unions the declaration into its declared set --
git diff --name-only includes deleted paths, so without that, authorizing a
deletion would immediately warn that the same path was out of declared scope.

Optional and additive throughout: files_deleted is absent from
PLAN_REQUIRED_FIELDS, a manifest entry without declared_deletions keeps the
original unconditional block, and omitting --deletions leaves the on-disk entry
shape untouched.

Supersedes the spent #2856 emitted-drift ack entry for execute-phase.md, the
same supersede that entry performed on #3370 and #3370 on #3324.

* fix(#3003): wire --deletions on every dispatch surface, not just one

Review found the feature inert on two of three dispatch paths. execute-phase.md
(harness inline) passed --deletions, but the orchestrator-worktree path
(executor-isolation-dispatch.md, worktree.create) and the Fleet-parallel batch
path (capabilities/claude-orchestration/fragments/execute-wave-pre.md,
worktree.record-agent) still passed only --files. A plan declaring
files_deleted would have merged on one path and been blocked on the other two
-- the exact bug #3003 exists to fix, left unfixed where most of the isolation
actually runs.

Worse, per-plan-worktree-gate.md already claimed --deletions was passed 'on the
same worktree.record-agent / worktree.create calls', which was false for both
untouched sites. A doc asserting coverage that does not exist is how a gap
survives review.

All four surfaces now pass the flag, verified by sweeping every .md under
gsd-core/, capabilities/, commands/, skills/ and agents/ that invokes
worktree.record-agent or worktree.create: each one that passes --files now also
passes --deletions. The isolation-dispatch note explains why this flag, unlike
--files, is not advisory -- omitting it does not skip a check, it blocks a
merge the plan declared.

Regenerates capability-registry.cjs, which the fragment edit made stale.

Neither newly-grown file needs an emitted-drift ack: executor-isolation-dispatch.md
sits under workflows/execute-phase/steps/ and execute-wave-pre.md under
capabilities/, both outside currentSizes()'s non-recursive scan of
gsd-core/workflows/ and agents/.

* docs(#3003): document files_deleted where a plan author will actually find it

The feature's entire user surface is one plan-frontmatter field, and the
canonical reference for that frontmatter -- docs/reference/plan-md.md, the table
that documents every other key -- never mentioned it. A field nobody can
discover ships as a field nobody uses. Adds the files_deleted row and an example
entry in all five locales (en, ja-JP, zh-CN, ko-KR, pt-BR), stating the property
that makes the opt-in safe: matching is exact per path after separator
normalization, with no globs and no directory prefixes, so a declaration can
never authorize more than it literally lists, and omitting the field keeps the
guard's original unconditional block.

Also corrects two claims in the scope-conformance how-to that this change made
false. Its opening paragraph described the recorded declared scope as
files_modified alone; declared_deletions is now unioned into that comparison.
Its "Renames are not detected specially" bullet asserted the deletions guard
blocks any entry whose diff contains a deletion, full stop -- which was the
whole point of #3003 and is no longer true. Reworked to say what now decides a
rename's fate: declare the old path in files_deleted and both halves become
ordinary paths for the advisory check, which is also why the old path needs no
separate files_modified entry.

Documentation that describes the pre-change behavior of the thing being changed
is worse than no documentation, because a reader trusts it.

* fix(#3003): close every review finding on the declared-deletions opt-in

Two independent isolated reviewers, correctness and security. Neither found a
blocker; both found real defects, and the directive treats a finding at any
severity as blocking. All of them are fixed here.

MAJOR -- the submodule worktree gate could not see a deletion-only plan.
per-plan-worktree-gate.md intersected $SUBMODULE_PATHS against $PLAN_FILES
alone, while $PLAN_DELETIONS was extracted and then never used. Before
files_deleted existed, a path had to appear in files_modified to be planned at
all, so the gate saw it; the new field plus the new docs telling authors a
deleted path needs no files_modified entry opened a hole where a plan whose only
submodule touch is a removal kept worktree isolation on -- the exact case #2772
disabled it for. Both channels now feed the intersection. Note the posture is
deliberately the OPPOSITE of the cleanup-wave guard: there the channels stay
apart because a deletion AUTHORIZATION must never be inferred; here they merge
because a safety fallback must never MISS a touch.

MAJOR -- same-wave conflict detection could not see a deletion. The planner's
implicit-dependency rule compared files_modified only, so plan A editing
src/x.ts and plan B declaring files_deleted: [src/x.ts] scored as conflict-free
and ran in parallel: one branch removing what the other is writing, which is the
sharpest conflict there is. Overlap is now computed across both channels.

MINOR (both reviewers, one root cause) -- the advisory union gave one field two
matching rules. declared_deletions was unioned into the scope list handed to
planWaveScopeConformance, which reads it with prefix-and-glob semantics. So a
field that is exact-match-only at the gate silently became wider at the
advisory: ["*.md"], inert at the gate, yielded a null prefix meaning "matches
everything" and muted the advisory completely, and ["src"] muted all of src/.
The union also activated the advisory on plans that declared no modification
scope at all, warning on every modified path. Replaced with subtraction from the
findings, gated on files_modified alone. One field, one rule, everywhere.

MINOR -- core.quotepath made the feature silently inert for non-ASCII paths.
git emits "tests/\303\251.ts" C-escaped and quoted, which never equals the
declared plain path, so a correctly declared deletion of tests/é.ts would block
forever with nothing pointing at the encoding. Both diffs now pass
-c core.quotepath=false.

NIT -- flag() consumed a following flag as a value, so --deletions --files x
swallowed --files and dropped both. Now treated as a missing declaration, which
fails closed. Fixed at both call sites; the helper is duplicated verbatim in
cmdWorktreeRecordAgent and cmdWorktreeCreate and leaving one would reintroduce it.

TEST -- one test passed for the wrong reason. "a declared deletion is in scope
for the advisory" asserted only that warnings omit the deleted path; under a
full revert the entry blocks first, warnings come back empty, and the negative
assertion passes anyway. It now asserts the entry actually merged, which is the
load-bearing half. Four regressions added, one per fix above.

Docs corrected rather than extended. The rename bullet in the scope-conformance
how-to claimed a rename whose delete side is undeclared never reaches the
advisory. Verified false: git's rename detection is on by default, so a pure
rename is a single R entry that appears in no --diff-filter=D output and was
never gated, before or after #3003. Only a rename that edits enough to fall
below the similarity threshold decomposes into add+delete. The pre-existing
sentence made the same wrong claim; this restates it correctly instead of
sharpening the error. The localized plan-md.md reference edits are reverted:
the PR template requires docs content added here to be English, and the
translations already lag by three fields, so English-only is the repo's
standing posture, not an oversight.

Agent-file size caps respected: gsd-planner.md is XL-tier by bytes but carries a
separate 49152-LF-CHAR cap asserted by four suites, so its edit is deliberately
terse and lands at 49141 with 11 chars of headroom, with the rationale moved to
docs/reference/plan-md.md, which has no cap. gsd-plan-checker.md lands at 49107
bytes, 45 under the LARGE cap. Both acks merged into the existing fragments that
already name those paths, since two ack sources may never name the same path.

* fix(#3003): decode git's path quoting instead of changing the git argv

The previous commit's non-ASCII fix turned the remote suite red: 44 failures,
42 of them "unexpected git call: -c core.quotepath=false diff --diff-filter=D
--name-only ...". The suite's git mocks match on exact argv, so adding two
flags to the deletions diff and the advisory diff invalidated every existing
fixture in tests/worktree-safety.test.cjs. Rewriting dozens of fixtures to
accommodate one flag would be paying a large Hyrum's-law bill to fix a small
defect.

Both execGit calls are reverted to their original argv. The C-quoting is now
decoded in normalizeScopePath instead, via a new decodeGitQuotedPath helper.
That is the better fix on its own merits, not merely the cheaper one: the git
argv is untouched so no fixture moves, the decode lands on the ONE normalizer
already applied to both sides of the comparison so the declared and reported
paths cannot disagree, and it holds regardless of the user's own core.quotepath
setting rather than only when we remember to override it.

A value not wrapped in a leading AND trailing quote is returned completely
untouched, so the plain-ASCII path -- the overwhelmingly common case -- is
byte-identical to before. Escapes decode to BYTES collected into a Buffer and
UTF-8 decoded only at the end, because \303\251 is two bytes forming one
character and decoding them separately yields mojibake. Malformed input never
throws: a trailing lone backslash or a short octal escape degrades to the
literal character, since one bad path must not take down a cleanup wave.

Caught while reviewing the helper: the non-escape branch pushed a UTF-16 code
unit rather than UTF-8 bytes. Git always escapes non-ASCII so its own output was
fine, but this normalizer runs on the DECLARED side too, and an author may write
a quoted path holding a literal é -- pushing 0xE9 alone is invalid UTF-8, so the
declaration would decode to a replacement character and silently stop matching.
That is precisely the failure this change removes, reintroduced on the other
side of the comparison. Now converts whole code points, surrogate pairs intact.

The other 2 failures: tests/parallel-dependent-plans.test.cjs pins the exact
unbackticked substring "files_modified overlap" in gsd-planner.md, and rewording
that comment to "declared-scope overlap" deleted it. The comment is restored
verbatim and the files_deleted change rides in the pseudocode and the Rule
sentence instead. Recorded in the ack fragment so the next contributor does not
rediscover it the same way.

Four regression tests cover the decode through the public cleanup-wave seam
(the helper is module-private): a declared non-ASCII deletion merges against a
C-quoted git report, the symmetric case where the DECLARATION is the quoted
form, an undeclared non-ASCII deletion still blocks with the residue naming the
decoded path an operator can act on, and a path merely containing a quote is
left alone. Plain ASCII was already covered and is not duplicated.

* fix(#3003): revert the leading-dash flag guard, the review nit was wrong

The remote suite came back with 2 failures, down from 44, and both point at the
same thing: tests/worktree-safety.test.cjs:7045 already pins the opposite
contract, deliberately.

  test('a flag-shaped --files value is not re-parsed as a flag', ...)
    recordAgent(['--files', '--branch'])
    -> files_modified === ['--branch']
    -> branch === 'worktree-agent-a1'  ("the real --branch value must be untouched")

So consuming the next argv element positionally, whatever its shape, is the
tested intent of this parser, not an oversight. The security reviewer's nit
claimed --deletions --files x would "swallow --files and drop both". It does
not: each flag runs its own indexOf, so --deletions records the literal
'--files' while --files independently still resolves to x. And that literal is
a path git never reports as deleted, so it authorizes nothing -- already
fail-closed with no guard at all. The guard bought no safety and silently
changed --files behavior along the way, outside this issue's scope.

Reverted at both call sites, which are byte-identical again, along with the test
asserting the reverted behavior and the docs sentence describing it. The nit is
recorded as REJECTED in the review artifact with the reasoning above, rather
than as fixed -- a finding that turns out to be wrong should leave a trace of
why, or the next reviewer files it again.

docs/CLI-TOOLS.md now states the positional-read behavior plainly instead, so
the next person meets it as documented intent rather than rediscovering it
through a red suite.

* chore(#3003): backfill changeset pr number to 3757

* test(#3003): cover parsePlanDocument's filesDeleted branch to clear the mutation gate

CI's Stryker shard for plan-document failed at 73.28 against a break threshold
of 75: 170 killed, 62 survived, 232 total. Eight of those survivors are the
filesDeleted block this issue added to parsePlanDocument, which shipped with no
direct coverage at all -- the field was exercised end to end through the
cleanup-wave tests, but the parser itself was never called with a plan that
declares it, so every mutant in the block lived.

Four tests, each pinned to specific mutants rather than written for coverage
percentage:

- absent key yields exactly [] -- kills the array-literal seed
  (["Stryker was here"]) and the `fmDeleted = true` conditional, which would
  otherwise produce ["true"]
- a scalar underscore `files_deleted:` wraps into a one-element array -- kills
  `fmDeleted = false`, the `&&` logical-operator swap, the `fm[""]` string
  mutation on the first operand, the emptied if-block, and the ternary's
  non-array branch
- an array-valued hyphenated `files-deleted:` maps element-wise -- kills the
  `fm[""]` mutation on the SECOND operand (only reachable when the legacy
  hyphen alias is the one carrying the value) and the ternary's array branch
- an empty list yields [] -- boundary case, and a genuinely distinct one from
  the absent key: [] is truthy in JS so it ENTERS the if, and only
  Array.isArray's true branch mapping over nothing produces the same []

Threshold arithmetic: 174 of 232 are needed for 75%, and these take it to about
178, so the shard clears with margin rather than landing on the line.

Every expected value was confirmed by executing the built parser before being
asserted, not inferred from reading the source.

738f42f4fd feat(#2398): consensus gate for CYCLE_SUMMARY on multi-reviewer runs (#3755)
* test(#2398): failing-first suite for the CYCLE_SUMMARY consensus gate

Binds the gate before it exists, so the suite is RED against next.

The load-bearing rows are the two the closed PR #2417 did not have. The B2
regression row asserts a judgment-class lone HIGH counts WITHOUT corroboration
when its raiser is unmarked — if anyone re-couples that class to corroboration,
more reviewers again produce a weaker gate than one, which is what closed #2417.
The parity row asserts every marker literal the gate names is one
review-lane-runner actually emits, so the gate cannot key on a signal nothing
produces; a mutation row and a seeded fast-check property prove that guard runs
its failure branch rather than only reading a correct tree.

Also pinned: gate position before Counting rules, the untouched CYCLE_SUMMARY
line shape the orchestrator greps, fence balance, the single-reviewer no-op,
classification by what a claim asserts rather than by citation presence, the
all-marked fail-open, current_actionable staying out of scope, and the
leading-marker requirement that stops a review which merely quotes a marker
from suppressing its own findings.

* feat(#2398): consensus gate for CYCLE_SUMMARY on multi-reviewer runs

With review.reviewer_instances running several reviewer identities off one
adapter, any single instance's fabricated HIGH could force a full replan cycle
on its own. Across ~9 real cycles on two projects each of four instances
fabricated at least once, and each was also the most accurate reviewer in some
other cycle, so dropping to fewer reviewers trades away real signal.

The gate engages only when 2+ reviewers actually ran, and weighs a lone HIGH by
what the claim asserts rather than by whether anyone agreed with it. An
existence claim -- a symbol, file, flag, commit or ID exists, is absent, or says
something specific -- counts only if source-grounding confirms it or another
reviewer raised the same concern. A judgment claim -- a design or correctness
property -- counts unless that reviewer's own section opens with an
evidence-quality discount marker the review lane already stamps
([reviewed-without-source-citations] #3194, [reviewed-without-repo-access]
#2176, or a diff-only lane).

That split is what resolves B2, the finding that closed PR #2417. B2 showed the
approved wording made more reviewers produce a WEAKER gate than one: condition
(a) pointed at the source-grounding pass, which verifies every symbol THE PLAN
cites and never takes reviewer claims as input, so a genuine architectural HIGH
that one reviewer caught and another missed was neither groundable nor
corroborated and stopped gating. Judgment-class findings are therefore exempt
from corroboration entirely -- reviewers catch materially different classes of
issue, and demanding two of them independently raise the same architectural
concern suppresses exactly what a multi-reviewer setup exists to surface.

Guards on the gate itself: an all-marked cycle disengages it, so a cycle in
which nothing was verified can never be counted as converged; the marker must
OPEN a reviewer's section, so a review that merely quotes a marker does not
suppress its own findings; a suppressed HIGH stays listed and tagged rather
than dropped; current_actionable is untouched; and a single-reviewer run is
unchanged.

No new command, config key, or dependency -- the gate reads signals that
already exist. The CYCLE_SUMMARY line shape the orchestrator greps is
unchanged; only the integer it computes moves, and only for 2+ reviewers.

Known limit, inherited rather than introduced: SOURCE_CITATION_RE checks
citation presence, not resolution, which src/review-lane-runner.cts records as
a deliberate #3194 scope boundary. A fabricated but plausible file:line still
gates.

Scope revised and re-approved on the issue before any code was written.

* test(#2398): make marker parity behavioral, and stop overclaiming the gate

Review found the parity tests were vacuous: they asserted a marker STRING
appeared in review-lane-runner.cjs's source text, never requiring the module or
calling the stampers, so they would pass even if stampUngroundedReview were
broken or never invoked. They now invoke the real exported functions and assert
what those functions PRODUCE — that an uncited review gains a leading marker
blockquote, that a review carrying a file:line does not, that a self-reported
blind review is stamped, and that stamping is idempotent. Removing the source
read also removes an incidental no-source-grep evasion via a parameterized path.

Review also found the changeset headline false for the class it matters most
in. The discount markers detect 'cited nothing' and 'had no repo access'; they
cannot detect 'drew a wrong conclusion from a real citation', so a judgment-class
finding invented by an evidence-bearing reviewer still counts alone. That is the
deliberate side of the tradeoff jags-faith named when closing #2417 — the
alternative is requiring corroboration for design findings, which is B2 — but
the changeset claimed lone hallucinations no longer force a cycle, full stop.
Corrected there, and stated plainly in docs/COMMANDS.md and the design record.

Also dropped the reviewer-instances.md entry from the emitted-drift ack: the
growth ratchet's currentSizes() scans only gsd-core/workflows/ and agents/
(tests/helpers/emitted-runtime.cjs:916-929), so references/ is outside it and
that entry acknowledged a delta the gate cannot see.

dacae92730 docs(#2845): record the inventory-provenance limits where readers meet them (#3746)
The limits shipped with #2845 were disclosed only in the PR body, which is
read once at merge and then buried. They are properties of what the feature
does, so they belong in the documentation.

Three surfaces, each at the point a reader forms an expectation:
docs/how-to/design-a-ui-phase.md gains a 'What this check is and is not'
subsection under the provenance how-to; docs/explanation/security-model.md
gains a residual-risk pair matching the section's existing shape; and
docs/AGENTS.md notes them where gsd-ui-checker's behavior is described.

The substance: a provenance line makes an inventory's origin falsifiable
rather than verified, since nothing re-runs the command or compares the
count; the rule is agent-applied like the other six dimensions, not a schema
check; and 'the checker never runs the recorded command' is an instruction
rather than a capability boundary, because the checker holds a Bash grant it
genuinely needs for the agent-skills bootstrap and tool grants here are not
command-scoped.

4918c62d76 feat(#2845): require provenance for UI-SPEC component inventories (#3745)
* test(#2845): failing-first suite for UI-SPEC inventory provenance

Binds two shared formats before either exists, so the suite is RED against
next: the gsd-ui-checker dimension roster (asserted independently on twelve
surfaces, eight English and four translated) and the provenance-line grammar
the UI-SPEC template emits and Dimension 7 consumes.

Every parity assertion is paired with a synthetic mutation case, so the guard's
failure branch executes rather than only reading a correct tree: limit-1 (a
surface still declaring 6), limit (7), limit+1 (8), a dropped dimension, a
label that drifts on one surface only, a non-contiguous roster, a duplicated
number, and a surface that stops declaring a count at all. A seeded fast-check
property renders the roster under formatting noise (CRLF, padding, interleaved
sections) and asserts the parse round-trips and is strictly sensitive to a
dropped heading.

Assertions are on parsed typed records, never raw substrings.

* docs: normalize design-a-ui-phase how-to to American English

House style for docs/ is American English (CLAUDE.md). This file carried
colour/initialisation/initialise/artefact throughout. Spelling only — no
content change; kept separate from the #2845 feature commit so the
release-notes classifier and the hotfix cherry-pick filter see it for what
it is.

* feat(#2845): require provenance for UI-SPEC component inventories

A UI-SPEC's component inventory was treated downstream as a closed allowlist
while the document recorded nothing about whether the list had been enumerated
from the installed design system or recalled from memory. A recalled inventory
is indistinguishable from an enumerated one, so an executor complying with the
spec builds against a fraction of what the package offers, and every gate stays
green because they assert semantics rather than composition.

The UI-SPEC template gains a Component Inventory slot carrying one of two
provenance lines: the command that enumerated the list, the count it returned,
the resolved package@version and the date; or a Could not enumerate record with
a real reason. gsd-ui-researcher gains an enumeration ladder and must record
the line rather than write the list from recall.

gsd-ui-checker gains Dimension 7. An inventory with no provenance line, a count
with no command, an empty could-not-enumerate reason, or a line still carrying
the template's unfilled placeholders BLOCKs; a partial line, a line placed below
its table, or an honest negative record FLAGs; a complete line passes, and so
does a spec carrying no inventory at all, which keeps every UI-SPEC predating
the dimension validating unchanged. Whatever the verdict, an unsourced inventory
is reported as a non-exhaustive list of known-good components rather than a
closed allowlist, so the executor is never blocked from a component the spec
merely failed to mention. The checker never runs the recorded command.

The dimension count moved on all thirteen surfaces that assert it, across five
languages. Also corrects the claim in the English, Korean and Portuguese how-tos
that this checker applies a scored six-pillar rubric — that rubric belongs to
/gsd-ui-review's retroactive audit.

72819a4616 fix(#3031): opt-in reclaim of GSD hooks orphaned in ~/.kimi (#3731)
* test(#3031): failing-first coverage for opt-in ~/.kimi legacy reclaim

Drives the user-reachable installer surface against a sandbox HOME seeded
with the pre-#2755 wreckage: a GSD [[hooks]] block, hooks bundle and
CommonJS marker orphaned in ~/.kimi by a --kimi-code install.

Covers the reclaim itself plus the four guards the diagnosis identified as
negative space: opt-in only (no flag, no deletion), user-authored TOML and
hook files preserved, a --kimi install never reclaiming its own root, and
the KIMI_SHARE_DIR/KIMI_CODE_HOME collision where both roots resolve to one
directory. Adds a fast-check property that stripping the block never
destroys user content.

Red until --reclaim-kimi-legacy exists.

Refs #3031

* fix(#3031): opt-in reclaim of GSD hooks orphaned in ~/.kimi

A --kimi-code install older than 1.10.0 wrote its GSD [[hooks]] block, hook
bundle and CommonJS marker into Kimi CLI's ~/.kimi. #2755 fixed the
destination but could not reclaim what the old bug already wrote: the stale
block is byte-identical to a legitimate Kimi CLI one — both runtimes render
the same bytes for the same root, since the command paths derive from the
hooks root, not the runtime — so no inspection can tell litter from a working
install.

Cleanup is therefore opt-in. `--reclaim-kimi-legacy` on a --kimi-code install
removes GSD's own artifacts from the legacy root; without it nothing is
touched, so a dual-product machine keeps Kimi CLI's hooks and #2755's
acceptance criterion holds.

Extracts the uninstall path's removal sequence into reclaimKimiHooksRoot() and
drives both callers through it, so the reclaim removes precisely what a real
uninstall removes rather than a hand-copied second implementation. Guards the
wrong-runtime case (a --kimi install would delete its own hooks) and the
KIMI_SHARE_DIR/KIMI_CODE_HOME collision where both roots resolve to one
directory.

Also corrects two pre-#2755 leftovers in the same surface that told users to
run `--kimi --config-dir ~/.kimi-code` — the form that produces this very
defect, since --config-dir moves only the skills root — and adds the missing
--kimi-code entry to the installer's own help.

Regression coverage folded into tests/kimi-upgrades.test.cjs beside the #2755
cases, per the regression-test-naming lint.

Fixes #3031

* fix(#3031): never reclaim ~/.kimi when this run also installs kimi

Found by the isolated adversarial review pass and independently while tracing
--all ordering, then reproduced.

selectRuntimesFromArgs orders 'kimi' before 'kimi-code' in both --all and an
explicit --kimi --kimi-code, and installAllRuntimes installs in that order. So
--all --reclaim-kimi-legacy installed a fresh, legitimate Kimi CLI hooks block
into ~/.kimi and then deleted it moments later from the kimi-code leg — exiting
0 and reporting success while leaving the user with no Kimi CLI hooks at all.
The collision guard could not catch it: kimi-code's own root is ~/.kimi-code, a
genuinely different directory.

The flag asserts "I only use Kimi Code"; installing kimi in the same invocation
falsifies that, so the reclaim is skipped with a notice.

Also hardens the collision guard itself. It compared path.resolve strings,
which returns false for two spellings of ONE directory — measured, not assumed:
a symlinked alias and a case variant on a case-insensitive filesystem both
compared unequal, so the guard would not have fired and the install would have
deleted its own freshly-written hooks. isSameDirectory now compares directories
via resolve, then dev+ino identity, then realpath.

Regression tests for all three cases; the two alias tests probe the real
filesystem and t.skip() where the alias cannot exist.

Refs #3031

* docs(#3031): reattach reclaimKimiHooksRoot's JSDoc to its own function

Inserting isSameDirectory anchored on the function name, which placed the
helper between reclaimKimiHooksRoot's doc block and the function it documents.
isSameDirectory ended up with two stacked doc blocks above it and
reclaimKimiHooksRoot with none.

Refs #3031

* fix(#3031): warn when --reclaim-kimi-legacy cannot apply

The flag only acts inside the kimi-code GLOBAL install branch. Passed with any
other runtime, or with --local, it was consumed in silence: exit 0, no cleanup,
no message. For a cleanup the user explicitly asked for, silence is
indistinguishable from "it ran and found nothing".

The scope warning is raised at argument-resolution time rather than inside
install(). kimi-code declares hostBehaviors.localInstallDeferred, so install()
returns early at the deferral check long before the kimi-hooks-toml branch — a
guard placed there is unreachable, which is both dead code and a linted drift
shape in this repo. Verified reachable by spawning the real installer.

Neither case is a hard error: the flag stays composable with --all, where it is
legitimately inert for the other seventeen runtimes.

Refs #3031

* docs(#3031): document every case where --reclaim-kimi-legacy skips

Refs #3031

* fix(#3031): resolve local config dirs from RUNTIME_META alone in the install harness

The remote runner surfaced this: the #3031 warning test drives a local
kimi-code install and died with "The path argument must be of type string.
Received undefined".

runMinimalInstall carried a SECOND, hand-maintained local-dir map beside
RUNTIME_META, and it had drifted — four runtimes present in RUNTIME_META
(hermes, kimi, kimi-code, zcode) were missing from it, so scope:'local' for any
of them resolved path.join(root, undefined) and threw a bare TypeError naming
neither the runtime nor the map at fault. #3023 had already hit exactly this
for pi and fixed it by adding one more entry, which left the divergence itself
in place for the next runtime to rediscover.

Local scope now reads RUNTIME_META.localDir, the same table the global branch
already reads, with the same loud named error the global branch raises. Parity
verified for all 14 previously-supported runtimes: every one resolves to a
byte-identical configDir. cline keeps its ternary — its local artifacts land at
the project root itself, which is a real exception, not a directory name.

Guarded in golden-parity-single-source.test.cjs beside the buildParityManifest
anti-divergence test, and both arms of that guard were proven able to fail.

9a69a86f42 enhance(#2971): strict planning filter mode for /gsd-pr-branch (#3720)
* test(#2971): failing-first suite for the pr-branch planning-path filter

Binds the not-yet-built planning.pr_strict mode and the corrected filter recipe
for /gsd-pr-branch across six layers: pure classification and forbidden-path
predicates, real-git fixtures that run the cherry-pick filter loop end to end,
config-key registration through the real CLI and both manifests, the executed
worktree-materialization claim the issue's triage asked to establish, fast-check
properties over arbitrary path sets, and a drift guard over the shipped workflow.

Two live defects in today's shipped recipe are pinned as regressions, both
reproduced empirically first: `git rm -r --cached` stages a deletion of any
.planning/ path the target branch already tracks, so the generated PR removes the
base branch's planning files; and the same command leaves the cherry-picked file
untracked on disk, so a second commit touching that path aborts the pick with
"untracked working tree files would be overwritten" and every remaining commit is
silently dropped.

The test helper parses the canonical path lists out of gsd-core/workflows/pr-branch.md
rather than restating them, so the workflow stays the single source of truth and the
suite cannot drift from what ships.

Refs #2971

* feat(#2971): strict planning filter mode for /gsd-pr-branch

Adds planning.pr_strict — a boolean, default false, that selects what
/gsd-pr-branch means by "filtered". Default mode is unchanged: structural
planning state survives into the PR branch and the nine transient
subdirectories do not. Strict mode drops every .planning/ path, structural
files included, and carries a commit over only when it touches at least one
file outside .planning/.

Strict mode is what makes planning.commit_docs: true safe for a project that
versions its planning tree locally but publishes none of it. The alternative
posture, commit_docs: false, silently costs parallel executor isolation — a
worktree is checked out from a commit, so an untracked or ignored .planning/
is simply absent inside it and the executor has no PLAN.md to read. That claim
is now established by an executed fixture rather than inherited.

The two path lists are declared once and both projections derived from them,
so create_pr_branch and verify can no longer disagree about what the filter
promised. verify previously counted every .planning/ path against a documented
success criterion of zero while create_pr_branch was specified to preserve five
structural files, so a correct run reported itself as failed on every phase
that touched STATE.md — which is every phase. It now asserts against the active
mode, and names the .planning/ paths default mode deliberately keeps rather
than trading a wrong signal for silence.

Two verified defects in the same recipe are fixed alongside, because strict
mode would have amplified both. `git rm -r --cached` staged a deletion for any
.planning/ path the target branch already tracked, so the generated PR removed
the base branch's planning files — under strict mode that would have been the
entire tree. The same command left the picked file untracked on disk, so a
second commit touching that path aborted the cherry-pick with "untracked
working tree files would be overwritten" and every remaining commit was
silently dropped. Both were reproduced against real git before being fixed.
The filter now forces excluded paths back to what the PR branch's HEAD carries,
in the index and the working tree; a conflict outside the filter halts instead
of being improvised past; a commit left empty by filtering is skipped rather
than failing. A clean-working-tree precondition makes the worktree half safe.

Closes #2971

* fix(#2971): unwind the checkout on a conflict halt, and test the real recipe

Two review findings, both fixed in place.

The isolated adversarial pass found that the conflict-outside-the-filter branch
exited while leaving the user checked out on the half-built PR branch with
cherry-pick state still live — this loop runs in the user's own working
directory, so stranding them there is a real cost even though it is not a
vulnerability. The branch now aborts the pick, returns to the original branch,
removes the partial PR branch, and says so before exiting.

The standards pass found the L2 fixtures executed a hand-written mirror of the
cherry-pick filter recipe rather than the recipe itself, so a reordering in the
workflow would not have been caught — and the order is load-bearing, since
restoring a path from HEAD before removing it inverts the filter. The helper now
extracts the canonical loop from the shipped workflow and the fixtures execute
that verbatim, which also gives the conflict-halt unwind above real coverage.
The drift guard additionally pins the two commands' relative order and asserts
the workflow carries exactly one canonical loop.

Also records the publication gate in the CONTEXT.md glossary next to the commit
gate it is distinct from.

Refs #2971

* fix(#2971): make the conflict-halt unwind actually unwind, and use the colon slash form

The remote matrix caught two defects in the previous commit.

The halt path claimed to restore the original branch but did not. `git
cherry-pick --abort` does not apply to a single `--no-commit` pick with no
sequencer file, and the fallback left the unmerged index in place, which makes
`git checkout` refuse — a failure the `2>/dev/null || true` then swallowed, so
the user was told they had been restored while still sitting on the half-built
PR branch. The unwind now drops sequencer state, hard-resets the disposable PR
branch to clear the unmerged index, and only claims a restore when the checkout
actually succeeded; when it does not, it says where the user is and gives them
the two commands to finish it by hand. Verified against real git: exit 1, the
conflict named, HEAD back on the original branch, the partial branch gone, a
clean tree and no CHERRY_PICK_HEAD.

Two runtime-loaded source artifacts used the retired `/gsd-<cmd>` hyphen form,
which names a command no runtime registers. The canonical authoring token for
workflows and references is `/gsd:<cmd>`; docs keep the hyphen form, so the
documentation added in this branch is unaffected. The comment in src/config.cts
moves to the colon form too, since it propagates into the generated lib.

14679b866b enhance(#2856): add default-off live-DOM UAT capability (#3716)
* test(#2856): add failing-first suite for the live-dom-uat capability

Binds the approved triage shape before any of it exists:

- containment — the execute:wave:post hook must not render unless
  workflow.live_dom_uat is true AND the capability resolves active
  (fail-closed on a missing state entry, and on a non-boolean value)
- criterion 4 — agents/gsd-executor.md carries no browser MCP family;
  asserted as an absence, which is the only way it is observable
- Hyrum guard — the pre-existing mcp__playwright__* branch must stay
  outside the key-gated block, or upgrading silently removes working
  automated UI verification for every current Playwright-MCP user
- parity — the browser glob list now lives in two surfaces (agent
  frontmatter + workflow detection block); the assertion fails if
  either gains or loses a family without the other

Red by construction: the capability, agent and workflow block do not
exist yet. Verified on the remote runner.

Refs #2856

* enhance(#2856): add default-off live-DOM UAT capability

A phase whose acceptance criteria needed a live DOM could not be
finished by the agent that executed it: gsd-executor carries no browser
tools, so it correctly returned checkpoint:human-action even though the
work was not human-only, just tool-less. Every such phase degraded to
"executed, then finished by hand in the orchestrator", and autonomous:
false could not distinguish "a human must judge this" from "the executor
lacks the tool".

Implements the shape approved at triage, not the one reported. The
executor's tools: line is NOT widened, in any configuration: for a
first-party agent the static list is the only control that exists
(ADR-1244 D2, ADR-857 D4, no per-dispatch override). Instead one
default-off capability owns the key, the agent, and the step:

- capabilities/live-dom-uat/ — activationKey workflow.live_dom_uat
  (boolean, default false), one additive step at execute:wave:post
  (onError: skip, gates: []), so it can never halt a wave
- agents/gsd-dom-verifier.md — the only GSD agent carrying browser MCP
  globs, in its own tools: line, with no Bash
- verify-work automated_ui_verification — a gsd:live-dom-families block
  naming both new families AND the key; presence alone never activates

Two independent fail-closed gates: isCapabilityActive renders a hook
only on state.active === true, plus the step's own `when`.

The pre-existing mcp__playwright__* branch keeps the gating it already
had and stays outside the new block. Pulling it behind a default-off key
would have silently removed working automated UI verification from every
current Playwright-MCP user on upgrade.

Also closes a host gap this surfaced: execute:wave:post dispatched only
contribution + gate, so ANY registered step was declared and silently
never run — exactly the single-kind hand-roll loop-hook-dispatch.md
names. Step 5.75 now dispatches every kind == "step".

The browser-profile lock is tolerated, not coordinated: --isolated is a
flag on the operator's own MCP-server registration that GSD neither
launches nor parameterizes, so the verifier reports could_not_look /
profile_locked, names the flag, and stops. DOM-VERIFY.md keeps
could_not_look and nothing_to_report distinct behind a closed reason
enum — collapsing them is the ambiguous-run-notes defect reported.

Verified on the remote runner.

Closes #2856

* fix(#2856): apply review findings from the orthogonal passes

Correctness pass (blocker):
- delete detectionBlockIsCrlfSafe. It was pass-always: it read the file,
  replaced LF with CRLF, then indexOf'd marker strings that contain no
  newline, so the replacement could not change the result and the
  assertion could never fail for the reason it stated. There is no real
  CRLF risk on this surface either — the gsd:live-dom-families block has
  no parser, only human and agent readers. Deleted rather than replaced,
  per the repo's pass-always-test rule.

Isolated security pass (two minors, both real):
- execute-phase.md step 5.75: this change is what first activates
  kind == "step" dispatch at execute:wave:post, which newly opens the
  ref.command shell path at that loop point. Our own step uses ref.agent
  and never touches it, but the door is now open, so the step-dispatch
  line carries the same in-context validate-before-shell warning the
  sibling gate-dispatch line directly below it already carries.
- gsd-dom-verifier: quoted page text in DOM-VERIFY.md is attacker
  influenced. Require it wrapped in inline code or a fence, kept short,
  and never left reading as a directive to the next reader.

Verified on the remote runner.

Refs #2856

* fix(#2856): settle the new-agent roster ripple

Checkpoint 2 returned 28 failures, none in the new suite — all of them
the guards that exist to make adding an agent a deliberate act. Each is
a real boundary that had to move:

- docs/AGENTS.md: Tools row must copy the frontmatter verbatim (#2526),
  so the browser globs lose their backticks; primary-agent counts 21->22,
  roster 33/34->34/35, Verifiers category 1->2
- docs/INVENTORY.md: roster completeness requires every agents/gsd-*.md
  to be classified exactly once
- gsd-dom-verifier: add the anti-heredoc instruction and the commented
  hooks: frontmatter pattern both agent gates require
- gsd-core/bin/shared/model-catalog.json: every shipped agent needs a
  profile entry (#3229)
- copilot-install / kilo-upgrades / qwen-upgrades: expected agent list
  and the 34->35 roster boundary
- execute-wave-post-gate-pipeline-e2e: execute:wave:post legitimately
  carries one step now. Asserted as an exact shape — one step, capId
  live-dom-uat, ref.agent gsd-dom-verifier, onError skip — so it stays a
  real guard against accidental change rather than being relaxed

Two findings worth naming:

mcp-tool-inheritance (#2526) rejected the agent for documenting
mcp__playwright__* while its tools: line withholds it — a dead
instruction that invites the agent to claim a path it cannot take. The
prose now names the Playwright MCP family without the dispatchable
token, in both the agent and the capability fragment.

runtime-launcher-parity rejected the new gsd_run call: each fenced block
is its own shell, so a workflow step file invoking gsd_run needs its own
canonical preamble. Propagated with scripts/sync-runtime-launcher.cjs.
That script also normalizes explore.md, which is unrelated pre-existing
drift the parity check tolerates, so it is reverted to keep this diff
scoped.

The emitted-drift ack supersedes the spent #3370 entry for
execute-phase.md — it is merged into next, so its ripple is absorbed at
the base and it can no longer clear anything. That is the same supersede
the #3370 entry itself performed on the spent #3324 fragment. Its
unrelated execute-plan.md entry is untouched.

Verified on the remote runner.

Refs #2856

* fix(#2856): drop the stale emitted-drift ack entry

The automated-ui-verification.md entry was written speculatively rather
than from a reported growth, and the check names that precisely: an ack
"written or reworded in THIS diff, but nothing here needed it, so it
explains nothing".

The growth tier keys on the bare filename as it appears under
gsd-core/workflows/ or agents/. automated-ui-verification.md is nested
under verify-work/steps/, so it was never in the tracked set — only
execute-phase.md was ever reported, both before and after the launcher
preamble landed.

Only ack what the check actually reports.

Verified on the remote runner.

8df5cb36c2 enhance(#2951): refuse [VERIFIED] for a compatibility claim resting on absent metadata (#3718)
* test(#2951): pin the absent-evidence provenance contract (failing first)

17 tests / 22 anchors on the deployed agent text. Measured against the parent
commit: 20 anchors fail, 2 pass. The two that pass are the sibling-integrity
guards on the package-name and in-repo-value rules -- green before and after is
their intended signature.

Refs #2951

* enhance(#2951): refuse [VERIFIED] for a compatibility claim resting on absent metadata

A claim of the form "X does not support Y" drawn from MISSING metadata -- no
python_requires, no engines field, no per-version classifier, no changelog entry,
no matching support-matrix row -- no longer earns [VERIFIED] however
authoritative the source consulted. An absence is silence about every value, so
the same evidence would "prove" both the version being ruled out and the version
being standardized on. The only route from an absence to [VERIFIED] is a positive
falsification attempt with its failing output pasted; everything short of that is
[ASSUMED], which the file already routes to "needs user confirmation before
becoming a locked decision".

Third member of the family beside the package-name and in-repo-value provenance
rules, mirroring PR #2768's shape. A present declared constraint and an
affirmatively documented incompatibility are untouched.

Closes #2951

* fix(#2951): close the allow-list ambiguity and the mutation gap review found

Findings from the isolated adversarial pass and the two-axis review, all fixed:

MAJOR (x2, one root cause) -- the absence clause and the present-constraint
carve-out gave opposite verdicts on the same evidence for the commonest real
case: a classifier list enumerating :: 3.9 through :: 3.13 with no :: 3.14. A
researcher could read the enumerated list as a "declared" positive constraint
and re-earn [VERIFIED], which is also the evasion vector. The rule now states
the decision procedure -- does the declaration bound EVERY value or only the
ones it names -- and closes the positive-reframing restatement explicitly. New
contract test pins all four clauses.

MAJOR -- 'licenses a positive falsification attempt as the route to [VERIFIED]'
asserted two independent substrings and never that the route lands on
[VERIFIED]. A mutant swapping the tag for [CITED] or [ASSUMED] inverted the
rule and survived all 17 tests. Now pinned as one joined sentence.

MINOR -- the attributable-failure test regex-matched illustrative examples
("a missing certificate, a wrong host"), so a copy-edit would break it for no
reason; relaxed to the substantive clause. The no-paraphrase guard counted only
the heading, missing the drift mode in its own name; it now also pins the core
proposition to one occurrence, and the test name matches what it checks. An
off-by-one in the new allow-list regex bound (141 actual vs 140) is fixed.

MINOR -- docs/AGENTS.md listed four of the five governed absence forms while
the agent prose, docs/COMMANDS.md and the changeset listed five; three copies
disagreeing on list membership is the drift this repo treats as a defect.

SCOPE -- removed docs/how-to/verify-a-dependency-compatibility-claim.md and its
docs/README.md index line. Both reviewers flagged them as a seventh and eighth
surface beyond the six the requester capped, and CONTRIBUTING's "Agent or skill
change" row requires only docs/AGENTS.md. The actionable four-case guidance is
retained in docs/COMMANDS.md, which is inside the approved scope.

Ack byte figures corrected for the final size: 44250 -> 46602 (+2352), 2550
bytes headroom under the LARGE cap of 49152.

Refs #2951

* docs(#2951): restore the how-to the phase gate requires

Reverses the removal in 6404b43d3. Both /code-review axes had flagged
docs/how-to/verify-a-dependency-compatibility-claim.md and its docs/README.md
index line as a seventh and eighth surface beyond the six the requester capped,
and CONTRIBUTING.md's required-docs row for an "Agent or skill change" names
only docs/AGENTS.md, so they were dropped.

gsd-phase-gate.cjs then denied gh pr create: it refuses when the recorded
enablement sequence has more than one step and the how-to quadrant is empty.
The sequence here is genuinely four steps -- run plan-phase, read the [ASSUMED]
claim, probe or cite or accept it unlocked, then answer discuss-phase's
checkpoint -- and the last step lands on a different capability's surface, so a
reference table cannot carry it. Compressing the sequence to one step to unlock
howToSkipReason would be gaming the gate, which is the same Goodhart failure
this whole change exists to close.

A machine-enforced repo gate outranks two reviewers' scope preference and my own
reading, so the page is restored and the PR body discloses the two extra
surfaces instead of hiding them. Reverting is a one-file change if a maintainer
prefers the tighter scope.

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

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

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

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

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

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

Review findings from the standards, spec and security passes:

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

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

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

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

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

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

* chore(#2790): backfill changeset pr number

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

77fa08f1e8 fix(#2773): feed the spec-phase edge probe English-translated requirement text (#3713)
* test(#2773): failing-first contract and premise tests for translated edge-probe input

Locks the Step 5.5 contract that a response_language project must feed the
edge probe an English translation of each requirement's text, and binds that
advice to measured engine behavior: the same requirement classifies to zero
shapes in Portuguese and to collection/adjacency/empty/ordering in English.

Also pins the honest limit — the issue's own repro sentence classifies to []
in English too, so translation is necessary but not sufficient and the
authored shapes override is the documented fallback.

Red before the doc change; the assertions are all false today.

Refs #2773

* fix(#2773): feed the spec-phase edge probe English-translated requirement text

The shape cues in src/edge-probe.cts are English word-boundary regexes, so a
project running with response_language set wrote its SPEC requirements into the
Step 5.5 $REQS_JSON heredoc in that language, matched no cue, classified to zero
shapes, and landed every row in the unclassified sentinel (#1110). The taxonomy
contributed nothing and --auto left it all unresolved — the probe was a silent
no-op for exactly the spec type it exists to harden.

Step 5.5 now states that the $REQS_JSON payload is engine input rather than
user-facing output, so the response_language rule does not govern it: each
requirement's text carries a faithful English translation, the SPEC keeps its
original language, and requirement ids are never translated or renumbered. The
instruction sits before the heredoc on purpose — the downstream APPLICABLE=0
warning fires only when every requirement is unclassified, so a partly-classified
non-English spec would otherwise slip through with no signal at all.

Measured against the compiled engine: the same requirement returns [] in
Portuguese and collection -> adjacency/empty/ordering in English. Also measured:
the issue's own repro sentence returns [] in English too, so translation is
necessary but not sufficient — the instruction therefore points at the authored
shapes override for prose carrying no cue in any language rather than promising
that translation restores classification.

Doc scope only, per the triage disposition on the issue. The compiled engine is
untouched; the lang-hint / per-language cue-set fix is a separate follow-up.

Closes #2773

* fix(#2773): clean up the edge-probe temp file on the placeholder-guard exit path

Surfaced by the isolated security review of this branch. Between the mktemp and
the unconditional cleanup, Step 5.5 has two sibling guards that disagreed about
their own invariant: the engine-failure guard runs rm -f "$REQS_JSON" before
exiting, while the empty/placeholder guard directly above it exited without one.
A spec run that tripped the placeholder check therefore stranded a temp file
holding the SPEC's requirement text in TMPDIR, once per failed run.

The added contract test walks the region between the mktemp and the
unconditional cleanup and asserts no exit path leaves the file behind, so the
two guards can no longer drift apart. Proven to bind: run against the pre-fix
file the walker reports the leaking exit; against the fixed file it reports none.

Refs #2773

* docs(#2773): record the edge probe's English-cue input constraint in the predicate store

The co-change gate flagged CONTEXT.md (13 co-changes with spec-phase.md) and
docs/CONFIGURATION.md (11) as candidate-missing-updates, and both were real
gaps rather than incidental coupling.

CONTEXT.md's EdgeCompletenessProbeModule entry documents the input contract for
classifyShape but did not record that SHAPE_CUES are English word-boundary
patterns — so the predicate store implied text was language-agnostic, which is
what a future agent reads before touching this seam.

docs/CONFIGURATION.md's response_language row is what a non-English project
reads when it turns the setting on; it now names the one deliberate exception
and links to the FEATURES.md explanation, so the interaction is discoverable
from the config key rather than only from the workflow.

CONTEXT-INDEX.json regenerated via gen-context-index.cjs --write. The drift-ack
fragment is updated for the final byte range and now also records the
placeholder-guard cleanup fix folded into the same block.

Refs #2773

* fix(#2773): append the growth rationale to the existing spec-phase.md ack entry

The remote runner caught this: emitted-attribution.test.cjs pins the
0000-legacy-migration.json spec-phase.md entry permanently (the #2914 migration
regression test asserts the exact '31987 -> 31997' delta text survives), so
removing it to avoid a duplicate-key collision with a new fragment broke that
test instead of satisfying the ratchet.

The entry is an accreting log, not a single-use slot — #2733, #3132 and #3102
were each appended to the same reason string by later PRs, which is how a shared
growth key coexists with the rule that two ack sources may never name the same
path. This appends the #2773 rationale the same way and drops the separate
fragment, whose spec-phase.md key was the collision.

Verified locally by reproducing both affected tests against the real fragment
before re-dispatching: the pinned delta survives, grown[0].acked is true,
staleAcks is empty, and all 35 entries still read as spent.

Refs #2773

* docs(#2773): add a how-to for probing edges in a non-English project

The phase gate's enablementSequence check caught a wrong call of mine. I had
recorded that no how-to was owed because the user takes zero extra steps — the
workflow translates the probe input itself. Written out, though, the sequence
from off to value is two steps and step 1 depends on response_language, a
setting owned by a different capability than the edge probe, which is exactly
the condition the how-to test names.

There is also real task content a reference table cannot carry: the three-way
split between a few unclassified rows (the classifier's recall gap), every row
unclassified (the probe could not read the spec at all), and the silent
partly-classified case where the APPLICABLE=0 warning never fires. That last
one is what a user would otherwise misread as a clean bill of health.

Shaped after the resolve-edge-coverage-findings / resolve-unreachable-guard
siblings and indexed from docs/README.md next to its closest relative.

adb46cdd85 feat(#2734): surface STATE.md commit-age on the statusline (#3700)
* test(#2734): failing-first suite for the statusline STATE.md freshness marker

Binds the contract before any hook change exists: a `state ~N commits back`
segment gated on the state_head stamp landed by #2622, firing at the same
advisory threshold /gsd-health's W024 uses rather than at > 0.

Covers all five acceptance criteria — threshold parity (19/20/21 boundaries),
both renderers including formatGsdStateCompact, an exact spawn-count assertion,
repo-pinning and sub_repos degradation, and behavioral parity against
readStateHeadFreshness rather than a source-grep of the two fence copies.

52 example-based tests plus 5 seeded fast-check properties. Red now by design.

* feat(#2734): surface STATE.md commit-age on the statusline

Adds an opt-in `state ~N commits back` marker to the GSD-state segment,
consuming the `state_head` stamp and freshness contract landed by #2622.
A solo developer returning to a project reads "Phase 4, executing" in
STATE.md and acts on it, without noticing the codebase moved 40 commits
since that line was written. /gsd-health reports it as W024, but only if
you think to run it; the statusline is the surface you see without asking.

Fires at STATE_HEAD_ADVISORY_COMMITS (20), the same threshold W024 uses,
not at > 0: with commit_docs:true the commit carrying a STATE.md sync
advances HEAD by one, so > 0 would alarm permanently on a fresh project.

Costs exactly one bounded git subprocess per render and none when
disabled. `rev-list --left-right --count` answers ancestry and distance
together, and repo pinning is a filesystem check mirroring
projectOwnsItsRepo rather than a --show-toplevel compare, which is
unreliable on macOS /private/var and Windows 8.3 paths.

Every unresolvable input degrades to the tri-state unknown -- the marker
is absent, never a "fresh" claim the project cannot substantiate: a
malformed stamp, a root that does not own its .git, a sub_repos
workspace, history rewound past the stamp, or git being unavailable.

Also collapses statusline config resolution onto one resolveStatuslineOptions()
seam. runStatusline() and renderStatusline() duplicated it byte-for-byte;
one copy is what keeps a newly-added key from reaching only one of them.

* test(#2734): route the e2e spawn through the process seam and fix fixture leaks

Review findings from the two orthogonal passes:

- `bothEntryPointsResolveOptionsIdentically` spawned a child and substring-matched
  its stdout to test a pure function. It now calls resolveStatuslineOptions()
  directly — no subprocess, no text matching.
- `skipsFreshnessWorkWhenTodoTaskActive` genuinely needs a child (the !task gate
  lives in runStatusline, which reads stdin), so it now spawns through
  tests/helpers/process-seam.cjs and proves the negative with a filesystem fact:
  the git shim appends to a marker file on every invocation, and the assertion is
  that the marker never appears. Stronger than asserting text is missing, and it
  drops the last stdout substring match in the block.
- Every fixture-creating test now registers `t.after(() => cleanup(dir))` instead
  of a trailing cleanup(dir), which leaked the temp repo on assertion failure.
  derivationAgreesWithStateModule reassigns `dir` across five fixtures, so it
  binds each directory at scheduling time rather than cleaning only the last.

Also corrects markerCoexistsWithMilestoneComplete, which asserted the wrong
expectation rather than finding a code defect: `percent` drives the progress bar
too, so the milestone segment reads "v1.9 [##########] 100%". The marker appends
after it, which is what the test exists to prove.

CONTEXT.md's opt-in statusline key list was missing statusline.show_git as well
as the new key; both are now enumerated.

2fca0e17e4 enhance(#2554): resolve code review depth from path-scoped override rules (#3695)
* test(#2554): failing-first suite for path-scoped code review depth overrides

Binds the not-yet-built code-review-depth module: segment-aware path-prefix
matching of a changed-file set against ordered {paths,depth} rules, resolution
order flag > strongest matching rule > global > standard, typed validation
errors, and the large-scope downgrade boundary. Also proves behaviorally that
workflow.code_review_depth_overrides is not yet a registered config key.

Refs #2554

* feat(#2554): resolve code review depth from path-scoped override rules

Adds workflow.code_review_depth_overrides — an ordered array of {paths, depth}
rules matched against a review's changed-file set by segment-aware path-prefix
comparison. Resolution order is --depth= flag, then the strongest matching rule,
then workflow.code_review_depth, then standard; a matching rule replaces the
global rather than being max'd with it, so quick and standard rules stay
meaningful. Glob metacharacters are a hard configuration error rather than sugar
for a prefix, and malformed rules halt the review instead of degrading to
standard. The resolver is pure and reports its own provenance, so the workflow
can print the resolved depth and the rule that matched. The pre-existing
>50-file deep-to-standard downgrade moves into the module and now names the rule
it overrode.

The key is registered centrally rather than as a capability config slice: the
federated slice channel admits only boolean/string/number/enum, so an array
slice would be dropped as malformed.

Closes #2554

* test(#2554): correct depth-provenance assertions and pin out-of-repo paths

Two corrections to the failing-first suite. The source assertion for a
non-matching rule with no global configured expected 'config'; with no global
set the depth comes from the default, and a companion assertion tolerated
either value, so both passed against an implementation that derived provenance
from whether any rules existed rather than from where the depth came from.

The out-of-repo absolute-path case used a home-directory path that matched
neither implementation, so it never exercised the defect it named. It now pins
the discriminating cases: an absolute path outside the repo root must not match
a repo-relative rule, and one under the root must.

* docs(#2554): document path-scoped code review depth overrides

Reference rows for workflow.code_review_depth_overrides in the configuration,
features and commands references plus the locale copies that carry those tables,
and in the planning-config reference. Explanation of why escalation is
whole-review rather than per-file and why v1 is prefix-only. New how-to for
scoping review depth by path, carrying the configuration-error reason table and
the distinction between nothing to report and could not look. CONTEXT.md
glossary entry and the INVENTORY row for the new CLI module.

ja-JP and ko-KR CONFIGURATION.md carry no code_review keys at all, and ko-KR and
pt-BR FEATURES.md carry no code-review config table, so those files are
deliberately untouched.

* fix(#2554): make the depth-misconfiguration halt executable and reject control chars

Three review findings, all in this change.

The misconfiguration halt was prose rather than shell: the error-printing fence
was followed by an unconditional extraction fence, so an ok:false result threw
and left the depth empty instead of stopping the review. Prose is not a guard —
the two fences are now one block with a real conditional, and anything that is
not the literal string true fails closed.

An interior control character in a rule path survived validation and reached the
provenance string and the summary box; rule paths now reject control characters
via a new PATH_CONTROL_CHAR reason, after the glob check so precedence is
unchanged. That in turn makes the field record safe to delimit, so the seven
node invocations that each re-parsed the same result to read one field collapse
to one.

Also corrects the glossary entry's illustrative paths, which the glossary-ref
check read as real repository references.

* fix(#2554): use the fast-check v4 string API and acknowledge workflow growth

Two failures from the remote matrix on d3111f45, both this branch's.

The property block built its segment arbitrary with fc.stringOf, removed in
fast-check v4. Because the arbitrary is constructed in the describe body, the
throw took out all four property tests rather than one — they had never
executed. Rewritten to fc.string({unit, ...}), the form this repo already uses
in emitted-attribution.test.cjs. Every other fast-check helper in the file was
audited against the installed module.

The emitted-attribution growth arm needed an acknowledgment for code-review.md,
which grew 5376 bytes. The pre-existing 3503 fragment keying the same file is
spent — its ripple was absorbed when #3503 merged, and the base file is exactly
the 34435-byte baseline this growth is measured against — so it cannot clear
anything, while the ack lint hard-fails on a duplicate key across two sources.
Removed it in favor of the new fragment, which is exactly how #3503 itself
replaced the spent 3191 fragment.

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).

* 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.

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

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

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

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

Closes #2401

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

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

Independent review found three defects in the recognizer:

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

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

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

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

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

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

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

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

delta is exactly the two new reference paths per runtime, no removals.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

Refs #3411

* 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.

ac1b6d679f enhance(#3618): fold fallow-runner onto the canonical binary resolver (epic #3411 Phase 2) (#3633)
* chore(#3618): fold fallow-runner onto the canonical binary resolver

Epic #3411 Phase 2. src/fallow-runner.cts was the fourth divergent
implementation of Windows binary resolution the epic enumerated —
candidateNames, isExecutableFile, findInPath, findInNodeModules, 40 lines.
All four are deleted; resolveFallowBinary is one seam call.

Two OPT-IN options were added to resolveExecutableBinary to make the fold
behavior-preserving, both defaulting off so Phase 1's callers are byte-identical:

  prependPaths      dirs searched before env.PATH, in order, through the
                    identical per-directory candidate logic. This expresses
                    node_modules/.bin-first precedence without env surgery —
                    the rejected alternative re-introduced the
                    spread-loses-the-proxy hazard the Windows lane caught in
                    Phase 1, at every future call site instead of once.
  requireExecutable POSIX-only accessSync(X_OK); a no-op on win32 where mode
                    bits do not mean execute. Opt-in rather than default
                    because unconditional X_OK breaks #3445's suite, which
                    stages candidates with plain writeFileSync and never sets
                    an exec bit — the repo bans chmod in tests — so every one
                    would resolve to null on POSIX.

Deliberate behavior change on Windows: fallow's prior candidate list ended in a
BARE fallow. The seam never tries a bare name there, so an extensionless file
beside fallow.cmd is no longer resolved. That is the fix, not a regression — the
extensionless file is npm's POSIX sh shim, which CreateProcess cannot run
(#3275). Rows 7 and 8 of the design record it.

Defect found while working, fixed inline: the resolution order was documented
BACKWARDS as PATH-then-.bin in structural-pre-pass.md, docs/INVENTORY.md and
four INVENTORY translations. The code has always been .bin first, and .bin first
is correct — a project-local tool should beat a global one. The archived
changeset is left alone as a historical record.

fallow-runner had no test file at all. tests/fallow-runner.test.cjs is new
(F1-F15) and the seam options are pinned by S1-S12 folded into the existing
dispatch suite. RED proven by execution: with both source files stashed and
build:lib re-run, 7 of 27 probe cases failed.

Refs #3411

* chore(#3618): backfill changeset pr number 3633

* fix(#3618): assert both platform contracts in F4 instead of a POSIX-only premise

Windows CI on #3633 failed F4. The test monkeypatched accessSync to throw and
asserted resolveFallowBinary returned null — but that premise, that the X_OK
check is consulted at all, is POSIX-only by design. requireExecutable is a
deliberate no-op on win32 because Windows mode bits do not mean execute, so the
staged fixture correctly resolved there.

40-design.md's negative-space section already states this carve-out verbatim.
The test contradicted the design it was written from: fixtures were made
platform-adaptive in the previous commit, and this assertion was left
platform-blind.

F4 now asserts BOTH contracts — null on POSIX, resolves on win32 — rather than
skipping either. A t.skip on one lane would have been green and would have left
the win32 carve-out unpinned by fallow's own entry point.

Audited every other row for the same class. F1-F3, F5, F6, F11-F15 hold on both
platforms; F7-F10 and S1-S12 inject platform explicitly and are unaffected. F4
was the only row with a single-platform premise.

The local probe runs on one platform and structurally cannot catch this, which
is why it was green — that limitation is now stated at the top of the probe so a
green probe is not mistaken for platform coverage. The win32 branch was proven
by injecting platform:'win32' with accessSync throwing and asserting it still
resolves.

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

bf87dd4156 enhance(#3617): one canonical Windows binary resolver in the platform seam (epic #3411 Phase 1) (#3621)
* feat(#3411): one canonical Windows binary resolver in the platform seam

CONTEXT.md declares src/shell-command-projection.cts the single OS-facing seam,
but Windows binary resolution had grown four divergent implementations outside
it. #3445 folded two of them together — inside gsd-core/bin/gsd-tools.cjs, not
the seam — so the declaration stayed untrue and execTool still had no handling
at all.

Lift the resolver into the seam as resolveExecutableBinary, and export the half
that actually executes as projectSpawnInvocation: CreateProcess cannot run a
.cmd/.bat, so the cmd.exe mediation is inseparable from the lookup and splitting
them is how the copies accumulated. cmd.exe is invoked with an explicit argv
array, never shell:true — CVE-2024-27980's vector and Node 26's DEP0190.

execTool now resolves on win32. POSIX is a strict no-op by construction, which
matters: execTool rates CRITICAL blast radius (167 symbols, 53 files).
gsd-tools.cjs deletes its private scan and its private mediation and delegates.

Two semantics grown beyond #3445's resolver, both additive: a name already
carrying a PATHEXT-listed extension is tried as-is before the append loop, and a
suffix outside PATHEXT is not treated as an extension.

Refs #3411

* fix(#3411): keep mediating a declared .cmd that PATH resolution misses

Standards review caught a narrowing against the code this replaces. gsd-tools.cjs
computed `target = resolveSpawnBinary(binary) || binary` and keyed the shim test
on `target`, so a declared .cmd mediated whether or not PATH resolution found it.
That is load-bearing: resolveExecutableBinary scans PATH only, while `cmd.exe /c`
also finds a batch file in the current directory.

Mediation now keys on the target — resolved path, else declared name. The ENOENT
contract still holds for BARE unresolved names, which is the case it was written
for. P9/P10 pin both halves.

Spec review found E1/E2/E3/E5 promised by 50-test-matrix.md but never written;
added. E3 is the integration proof that the CVE-relevant mediation fires through
execTool, not only through projectSpawnInvocation in isolation.

Also adds the CONTEXT.md glossary entry for the seam's new resolution ownership
(a PR gate) and the changeset fragment.

Refs #3411

* fix(#3617): pass mediated cmd.exe arguments verbatim so metacharacters cannot inject

The isolated security pass found the mediation shape carried an argument-injection
surface. libuv's quote_cmd_arg force-quotes an argv element only when it contains
a space, tab, or quote — never for a cmd metacharacter — and cmd.exe re-parses
everything after /c. So an arg of a&calc arrived unquoted and cmd ran calc.
Node's own CVE-2024-27980 escaping cannot help: it fires only when the spawned
FILE is the .bat/.cmd, and here the file is cmd.exe.

Caret-escaping is not a fix. It is correct only when libuv does not quote, and
libuv quotes whenever the arg also contains a space — no per-arg transform is
right in both cases. So build the command line and pass it through verbatim, the
shape Rust's std adopted for the sibling CVE-2024-24576: one outer quote pair
that cmd /c strips, every token inside force-quoted, embedded quotes doubled.

An argument containing CR or LF is refused rather than mediated — a newline
cannot be represented in a Windows command line, so mediating would silently
truncate. Failing visibly is correct.

Known limit, documented at the seam: %VAR% still expands inside a /c string and
has no escape outside a batch file. That is information disclosure, not arbitrary
execution, and is the same limit Rust's std documents.

This was byte-for-byte the shape #3445 shipped, so the fix closes it for the
reviewer-lane spawn path too, not only for execTool's newly reachable route.

Refs #3411

* docs(#3617): document the subprocess-execution security posture

Adds Layer 4 to the security model: why GSD never uses shell:true for binary
invocation (CVE-2024-27980, Node 26 DEP0190), why resolution is explicit and
never tries the bare name on Windows (the npm extensionless-shim trap behind
#3275), and why .cmd/.bat mediation builds a verbatim force-quoted command line
rather than relying on default escaping — Node's own CVE protection cannot fire
once the started program is cmd.exe.

The residual %VAR% expansion limit is stated plainly under Trade-offs rather
than left implicit: it is information disclosure, not arbitrary execution, and
callers passing untrusted text to a Windows .cmd should not assume the value
arrives byte-identical.

Docs-only; no code change.

Refs #3411

* chore(#3617): backfill changeset pr number 3621

* fix(#3617): read PATH, PATHEXT and ComSpec case-insensitively

The Windows CI lane on #3621 failed E5, and the root cause was a defect in the
implementation, not the assertion.

Windows names the variable Path, not PATH. process.env is a case-insensitive
proxy, so process.env.PATH works — but execTool builds
{ ...process.env, ...opts.env } whenever a caller supplies opts.env, and
spreading discards the proxy while keeping the OS's actual casing. The exact-case
env['PATH'] lookup then returned undefined, the PATH scan saw zero segments,
resolution returned null, and the change degraded to precisely the spawn ENOENT
it exists to fix. ComSpec and PATHEXT had the same exposure.

#3445's tests never caught it because they pass uppercase keys explicitly, and
neither did the Linux remote runner — this is a defect only the Windows lane
could see.

_envGet resolves a variable by exact match first (so a canonical caller pays no
scan) and falls back to a case-insensitive sweep.

R23 and P16 pin it and were proven RED by execution: with the fix stashed and
build:lib re-run, R23 returned null and P16 returned the cmd.exe default.

R24 was rewritten because the first version was vacuous — it staged foo.CMD, so
the default PATHEXT already contained .CMD and it passed against the broken code
for the wrong reason. It now stages foo.XYZ, an extension absent from the
default, and carries a negative control asserting that dropping the Pathext key
yields null. Re-proven RED the same way.

E5's assertion was corrected alongside the fix: 'PATH' in options.env expressed
the wrong contract. It now checks case-insensitively for the key.

Refs #3411

* fix(#3617): execTool spawns the declared name unless mediation is required

The Windows full-test lane on #3621 failed tests/graphify.test.cjs — the python3
identity check asserted 'python3' and got the absolute resolved path
C:\hostedtoolcache\windows\Python\3.12.10\x64\python3.EXE instead.

Those tests are correct and the change was wrong. They pin a long-standing
contract — execTool spawns the program name it was given — by spying on
spawnSync's first argument, and routing every win32 call through the projected
invocation broke it.

Resolving a .exe buys nothing. libuv's CreateProcess path already performs
PATH + PATHEXT search, which is why spawning a bare 'node' has always worked on
Windows. The only case the OS genuinely cannot spawn is a .cmd/.bat. So execTool
now adopts the projection only when mediation actually happened —
windowsVerbatimArguments is exactly that flag — and otherwise passes the declared
program and args through untouched.

40-design.md already rejected gratuitous change for this reason: symmetry is not
worth a behavior change to 53 files that fixes nothing. That reasoning was
applied to POSIX and missed the win32 non-batch case. Rows 5 and 20 now record
it, and the CONTEXT.md glossary states the caller-choice rule.

deps.spawn deliberately still adopts the resolved path: its hasBinary probe
answers from the same resolver, so probe and spawn must agree on the exact file
(#3445). The asymmetry is now documented at both call sites rather than latent.

E7 pins the restored contract and was verified by executing execTool against a
monkeypatched spawnSync: python3 in, python3 spawned.

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.
