* fix(#3648): resolve base_branch precedence inversion and round-1 findings

Blocker 1/2: production config resolution was flat-first, so a project
that migrated to git.base_branch but still carried a stale flat
base_branch got the old value back. Add base_branch to
normalizeLegacyKeys (mirrors the existing branching_strategy/sub_repos
pattern: canonical nested wins) and route readEffectiveGitConfig's
test seam through the same normalization so it can't silently diverge
from production again. Adds a regression test with both keys set that
fails without the fix.

Blocker 3/4/5: restore the handle_branching case-selector prose and
"none" contract sentence that #3389's tests anchor on, and revert the
unrelated prose/comment compaction in the same step — both were
drive-by edits outside #3552's scope.

Also addresses review majors/minors: delete readConfigBaseBranch and
readConfigProtectedBranches (dead in production, only self-tested);
--is-protected now fails closed (reports protected) instead of
silently answering false when the base branch can't be verified;
trim configured protected-branch names; fix HOME-without-USERPROFILE
vacuous isolation on Windows; correct the drift-ack's byte accounting.

* test(#3648): add failing legacy-key hoist safety coverage

Round-2 review found normalizeLegacyKeys block 5 records a normalization
carrying the DISCARDED flat value on the canonical-wins branch. Probing
that turned up a second, unreported defect in the same helper shape:
blocks 1, 2 and 5 all spread result['git'] / result['planning'] with no
object guard, so a config whose section key holds a string is spread into
index keys —

  {"git":"main","base_branch":"release"}
    -> {"git":{"0":"m","1":"a","2":"i","3":"n","base_branch":"release"}}

The resolved value is accidentally still correct, so nothing fails and no
diagnostic fires. But normalizations.length > 0 sets configDirty, and
config-loader then serializes that shape back into the user's
config.json — a read that silently corrupts config.

The deleted #3057 W3 suite covered {"git":"main","base_branch":"release"}
explicitly; this is the input it would have caught.

Covers both defects across blocks 1 and 5, with object/array/null
negative controls that must stay green in both phases, and a fast-check
property over arbitrary `git` values.

* test(#3648): pin fail-closed handling of malformed protected_branches

Replaces the test that pinned the fail-OPEN behaviour. The old
assertion — ['develop', 42] yields isProtected === false for 'develop' —
locked in the exact failure #3552 exists to close: config-set validation
is bypassable by a direct edit of .planning/config.json, so a user who
believes 'develop' is protected got a silent false and no warning.

It was also inconsistent with the fail-CLOSED direction twelve lines
away, where an unverified base reports protected and writes a
diagnostic. A protection predicate must not have two opposite failure
directions depending on which input is bad (#3648 review Blocker 3).

New coverage: a bad element drops only itself, a non-array contributes
no names, an empty list is well-formed rather than malformed, and
--is-protected surfaces the rejection. Both negative controls — a clean
list reports nothing rejected and writes no diagnostic — must stay green
in either phase, so the reject channel cannot fire unconditionally.

* fix(#3648): drop only invalid protected_branches and report them

Partition git.protected_branches instead of discarding the whole list on
one bad element, and carry the rejections out through
ProtectedBranchStatus so --is-protected can name them on stderr. Valid
names keep protecting; the user finds out the rest were ignored.

A non-array value still contributes no names — a bare string is not a
list of branch names — but is now reported rather than swallowed. An
empty array stays silent: declaring no extra protected branches is a
valid choice, not a misconfiguration.

writeDiagnostic is hoisted out of the unverified-base branch since both
arms now use it.

* test(#3648): prove the predicate diagnostic survives both call sites

The workflow bash stub now emits a stderr diagnostic the way the real
command does, which is what makes a swallowed `2>/dev/null` visible to a
test — previously the stub was silent on stderr, so discarding it changed
no observable behaviour and the call sites could drop the explanation
undetected.

Adds the Minor 2 binding check as well: ship must expose the predicate
result as IS_PROTECTED rather than only echoing a warning, asserted by
running the extracted bash and reading the bound value, not by grepping
the workflow source.

Both tests carry opposite-outcome controls — an empty diagnostic must
leave the text absent, and a false predicate must bind false.

* fix(#3648): surface the predicate diagnostic and bind ship's result

Drop `2>/dev/null` from the --is-protected call at both call sites. The
fail-closed explanation and the new rejected-entry warning both go to
stderr, so discarding it left the user with a bare "protected branch"
warning on a branch that is not protected and no way to tell a real
match from a degraded-git guess. `git branch --show-current` keeps its
own redirect — that one is genuine noise.

ship.md binds IS_PROTECTED and its prose now branches on the variable,
so the following steps have evaluable state instead of having to infer
it from warning text in tool output.

execute-phase.md byte accounting refreshed: 92326 -> 92645, net growth
319 bytes (was 331 before the redirect came out). Baseline re-verified
against the current rebase base by blob id; the ceiling check passes
with 755 bytes of margin.

* test(#3648): restore negative space for the readFile config seam

The #3057 W3 suite was deleted with readConfigBaseBranch, but every arm
it pinned survives verbatim in readEffectiveGitConfig's readFile branch —
the JSON.parse catch, the non-object guard, the git-section object guard,
.trim() and blank-string rejection — and the four surviving readFile
injections were positive-path only. protected_branches was never driven
through this seam at all.

Restores nine cases against the seam, including protected_branches
partitioning, plus a control proving loadConfig still wins when both
seams are supplied.

Records honestly what the suite pins. Mutating the built lib shows
.trim() is KILLED, while the non-object guard and the blank-string
rejection SURVIVE — both are unreachable through this entry point for
the same reasons the deleted suite documented against its own
equivalents: a JSON-parsed non-object carries no relevant own-property
either way, and a blank value is rejected a second time downstream by
the resolver's truthiness check. They stay as defence-in-depth and are
labelled known-unkillable rather than left looking like coverage this
suite does not provide.

* test(#3648): distinguish detached HEAD from a missing branch argument

`args[1] ?? ''` collapsed two different situations into one: a detached
HEAD, where `git branch --show-current` legitimately prints nothing, and
the flag being called with no argument at all. Both answered false, so
the right outcome arrived by an unintentional path and a caller bug was
indistinguishable from normal operation.

Asserts the detached case stays silent and the missing-argument case
reports, with a control that the two diagnostics differ.

* fix(#3648): report a missing --is-protected branch argument

Answer false either way, but say so when the flag arrives with no
argument. A detached HEAD passes an explicit empty string and stays
silent, since that is a normal state rather than a misconfiguration.

* docs(#3648): state exact-name matching and per-entry rejection

isProtected is exact string equality, so a git-flow project must
enumerate every release/* and hotfix/* by name. #3552 only asked for an
integration-branch field, so the implementation satisfies the letter of
the issue while leaving its git-flow motivation partly unserved — say so
where users will meet it rather than leaving them to discover it.

Also documents the Blocker 3 behaviour change: an invalid entry is
ignored with a warning naming it and the remaining names still apply.

Both statements land in docs/CONFIGURATION.md and
gsd-core/references/planning-config.md, and the config-field-docs parity
test asserts each in both so the two cannot drift.

* refactor(#3648): extract isValidProtectedBranches for cross-surface pinning

The `git.protected_branches` check inside `cmdConfigSet` and the resolver's
per-entry filter in `git-base-branch.cts` are deliberately different shapes —
all-or-nothing on write, per-entry on read, so a hand-edited config.json cannot
fail the guard open. Nothing structural keeps their two definitions of "usable
branch name" in step.

Lifting the write-side check into a named, exported predicate lets a property
test ask both surfaces about the same value and assert they agree, which is the
fast-check gap the round-2 review flagged. No behaviour change: the predicate is
the same expression, called from the same place.

* fix(#3648): stop --is-protected rewriting the config it is asking about

`gsd_run query git.base-branch --is-protected` runs on every execute-phase and
every ship. It resolved config through `loadConfig`, whose normalize-then-write
path rewrites `.planning/config.json` whenever any legacy key normalizes — so a
boolean question was silently editing the user's checked-in config. This PR had
widened the trigger by adding a fifth normalization block (top-level
`base_branch` -> `git.base_branch`), making it fire for exactly the projects the
feature targets.

`loadConfigResolved` gains `options.persist` (opt-OUT, default true): resolution
is unchanged, only the two write-back side effects are suppressed. The predicate
passes `persist: false`; the ~30 other callers are untouched, so a legacy config
is still migrated by ordinary use.

Asserted on BYTES rather than parsed shape, because the rewrite reorders keys and
reflows whitespace even when the values are equivalent. Three tests, each with
its own control: the end-to-end CLI leaves the file byte-identical while still
answering `true` from the legacy key (proving the config WAS read); an ordinary
persisting load of the same fixture DOES change the bytes (proving the fixture
is live rather than inert); and `persist:false` vs default over one directory
returns deep-equal config while differing on the write. Reverting the one-line
`persist: false` fails the first of those and only that one.

Also from the review:

- `readEffectiveGitConfig`'s comment claimed the readFile branch routed "through
  the same precedence authority production uses". It does not, and cannot — it
  reproduces two of production's steps over a single file. The comment now names
  what the seam covers and what it does NOT (root/workstream deep merge, builtin
  and global defaults, federated merge), and the seam now applies production's
  flat-then-nested lookup so it stops disagreeing about a surviving flat key.

- The missing-argument diagnostic promised "answering false", which the
  fail-closed guard on the same call can contradict by printing `true`. It now
  states what it did with the argument and leaves the answer to stdout.

* test(#3648): re-pin block 5 on #3760's refusal contract

#3767 landed on next while this PR was in review and fixed the non-object
config-section defect properly: a present-but-non-object section now BLOCKS its
own migration — value preserved, no Normalization pushed, refusal reported via
`skipped[]` — rather than being rebuilt from a plain-object view. That supersedes
this branch's round-2 `hoistLegacyKey`, which prevented the character-key spread
but still dropped the section value silently, and which the round-3 review
correctly called out as destruction in place of corruption. The rebase drops that
commit and routes block 5 through the upstream helper.

This file's tests asserted the superseded design, so they are rewritten to pin
block 5 — `base_branch` -> `git.base_branch`, which did not exist when #3760's
suite was written — against the contract that now governs it: ordinary hoist into
an absent/null/object section, canonical-nested-wins, and refusal for each of
string/number/boolean/array sections with the exact `skipped` entry.

Two controls keep it from passing vacuously: the refusal must be scoped to block
5 (an unrelated block still normalizes in the same call), and a property over
arbitrary `git` values asserts hoist and refusal are exhaustive AND mutually
exclusive per key, that a refusal leaves both the section and the legacy key
untouched, and that a hoist manufactures no index key the input did not carry.

* docs(#3648): correct the Git Query and Config Loader module contracts

CONTEXT.md's Git Query Module still described base-branch tier 1 as a direct
`.planning/config.json` read. Since this PR it is the EFFECTIVE configuration
resolved by the Config Loader — a materially different authority, carrying the
root/workstream deep merge, flat-then-nested lookup and builtin/federated
defaults. The `--is-protected` predicate, `git.protected_branches`, and the two
invariants that distinguish the predicate from the plain query (fails closed on
an unverified base; must not write) were undocumented entirely.

The Config Loader entry now states that loading is not side-effect-free by
default and documents `options.persist`.

docs/INVENTORY.md's `git-base-branch.cjs` row carried the same stale ladder and
no mention of the predicate. `node scripts/gen-inventory-manifest.cjs --write`
was run and produced no diff: the manifest indexes roster NAMES, not row prose,
so a description edit cannot move it.

Also closes the global-defaults minor: `git.protected_branches` is inert in
`~/.gsd/defaults.json`, but so is every other `git.*` key — no branch-policy key
appears in `_globalBaseCfg` or `GLOBAL_DEFAULTS_RESOLUTION_KEYS`. That is
section-wide and predates this PR, so the fix is to state the scope where users
meet it rather than to quietly extend the resolution set for two new keys.

* fix(#3648): close four defects found by the round-4 external review

Two external reviewers (codex, antigravity/Gemini 3.1 Pro) were run adversarially
against this branch. Four findings reproduced against source; each is fixed with a
failing-first test and a control, and each fix was verified by reverting it and
watching exactly the intended test fail.

1. `persist:false` was DROPPED by the workstream fallback (codex). Blocker 1 was
   only half closed. `loadConfigResolved` re-enters itself with a bare
   `{ workstream: null }` when a workstream has no config.json of its own, and
   that literal discarded every other option — so the recursive pass ran at the
   DEFAULT persistence and rewrote the ROOT config. Reproduced: with
   GSD_WORKSTREAM=alpha and a legacy flat `base_branch`, `--is-protected`
   rewrote `.planning/config.json` despite `persist:false`. Both recursions now
   forward `options` and override only `workstream`; the explicit override still
   wins the hasOwnProperty check, so spreading cannot let `workstreamContext`
   reintroduce a workstream.

2. Both workflow call sites failed OPEN, and aborted under `set -e` (both
   reviewers, independently). `IS_PROTECTED=$(gsd_run ...)` yields an empty
   string when the query fails, so `[ "$X" = true ]` was simply false: no
   warning, no trace — a silent hole in the guard whose only job is to warn. The
   bare assignment also aborted the step under `set -e`. Both sites now degrade
   VISIBLY: `|| IS_PROTECTED=""`, then an explicit empty-string arm that says the
   check did not run. Deliberately not fail-closed — claiming "protected" on no
   evidence would warn on every branch whenever gsd-tools is unavailable.

3. `isValidProtectedBranches` and the resolver disagreed on a sparse array
   (antigravity). `.every()` skips holes; the resolver's `for...of` yields
   `undefined` for them, so `["main", , "develop"]` was accepted by config-set
   and rejected by the resolver. The cross-surface property passed only because
   `fc.array` cannot generate a hole. The predicate now indexes, and the
   generator punches holes so that axis is actually falsifiable. JSON cannot
   express a hole, so this is unreachable in production — but two definitions of
   one predicate must not contradict each other.

4. A top-level `protected_branches` silently outranked `git.protected_branches`
   (antigravity). Routing the key through `get(key, {section, field})` gave it
   flat-then-nested precedence, which is back-compat for keys
   `normalizeLegacyKeys` migrates. `protected_branches` is new in #3552 and has
   no legacy form, so that invented an undocumented alias. It now resolves
   nested-only through a new `getNested`, in production and in the test seam.
   `base_branch` keeps flat-then-nested — it HAS a legacy spelling that #3760's
   refusal path can leave behind — and a control pins that distinction.

Also narrows a CONTEXT.md claim this round introduced. The predicate fails closed
only when a git query TIMED OUT or could not be spawned (#3057 B4's `verified`);
a git command that runs and exits non-zero counts as a clean negative, so a cwd
that is not a repository answers `false`, not `true`. Verified pre-existing on
next @ 738f42f4, so the documentation was over-claiming rather than the code
regressing — but an over-broad contract is exactly what the module docs must not
carry.

Both workflow byte figures re-derived after the call-site change:
execute-phase.md 92356 -> 92865 (+509), ship.md 36784 -> 37227 (+443).

* test(#3648): pin git config read parity

* docs(#3648): document git query contracts

* fix(#3648): expose protected branch default

* test(#3648): snapshot planning tree for read-only query

* test(#3648): pin planning snapshot stray-write detection

* fix(#3648): resolve merge conflict from #3078's ack-fragment sweep

next swept the fully-spent 2818/3003 ack fragments this branch had
appended to (#3078, a84f7563). Rebased onto upstream/next and took
the deletions on both, then moved the #3552 append into a new
fragment of its own.

Rebasing onto the current base also left execute-phase.md only 34
bytes under the frozen ADR-857 Phase 6 margin ceiling (93400 bytes) —
intervening next PRs consumed the rest while this PR was in review.
Extracted the "none" arm's protected-branch-warning bash block into
gsd-core/workflows/execute-phase/steps/protected-branch.md (content
unchanged, matching the existing steps/ extraction pattern used
elsewhere in this file) so the inline growth is a one-line pointer
instead of the full block. 93366 -> 93385 bytes (+19), 15 bytes
inside the ceiling.

* fix(#3648): drop stale ack entry for the new step file

The extracted execute-phase/steps/protected-branch.md needed no
acknowledgment of its own — the differential-attribution check flagged
the entry as stale once the build ran, so removed it and kept the two
growth entries (execute-phase.md, ship.md) that actually needed one.

* fix(#3648): follow the step-file reference in the bash-extraction test helper

extractProtectedBranchWarningBash() read the "none" arm's bash block
directly out of execute-phase.md. That block now lives in
execute-phase/steps/protected-branch.md (byte-ceiling extraction);
the helper follows the step-file reference and extracts from there
when no inline block is found, so the three execute-phase tests that
execute this bash for real keep exercising the actual behavior.

* fix(#3648): regenerate INVENTORY-MANIFEST.json and satisfy the CRLF-fragile lint rule

- gen-inventory-manifest.cjs --write to pick up the new
  execute-phase/steps/protected-branch.md entry (already covered by
  docs/INVENTORY.md's generic workflow_steps wildcard row, so no
  INVENTORY.md edit is needed).
- Reworked the step-file-reference lookup in
  extractProtectedBranchWarningBash() to avoid a bare-\n regex split
  on file content (local/no-crlf-fragile-split), using the same
  line-array scan the function already uses elsewhere.

* fix(#3648): regenerate golden install-tree fixtures for the new step file

npm run gen:install-tree, adding gsd-core/workflows/execute-phase/
steps/protected-branch.md to all 19 runtime install-tree fixtures.
CI's tests/golden-install-tree.test.cjs caught this on push — I'd
verified the differential-attribution and INVENTORY-MANIFEST checks
but missed this separate golden-fixture check for the new file.

* fix(#3648): add the canonical gsd_run preamble to the new step file

CI's runtime-launcher-parity suite requires exactly one canonical
resolver preamble in every workflow .md that calls gsd_run. The
inline "none"-arm block never needed one (execute-phase.md already
carried a preamble elsewhere in the same file), but the extracted
execute-phase/steps/protected-branch.md is now its own file with no
preamble of its own. Ran node scripts/sync-runtime-launcher.cjs to
insert it (execute-phase.md itself is untouched — still 93385 bytes,
inside the ADR-857 ceiling).

That preamble defines its own gsd_run(), which shadows the mock
tests/git-base-branch.test.cjs injects for the three #3648 tests that
execute this bash for real — without stripping it, those tests reached
the real gsd-tools.cjs on the machine running them instead of the
test's fixture. Preamble correctness is already covered by
tests/runtime-launcher-parity.test.cjs, so extractProtectedBranchWarningBash()
now strips the preamble line before handing the block to the harness;
it only needs to exercise the #3552 warning logic.

* fix(#3552): address PR 3648 review feedback on protected branch warnings

- Fix execute-phase handle_branching branching_strategy=none instruction
  to "Read and execute execute-phase/steps/protected-branch.md"
- Use io.error(..., ERROR_REASON.USAGE) for cmdGitBaseBranch usage errors
- Align git.protected_branches schema default to (none) without fallback []
- Relocate CONTEXT.md forward-referencing sentence into module body
- Sanitize control and ANSI characters in renderRejected diagnostics
- Clean up out-of-scope whitespace hunks in gsd-tools.cjs

Emitted-Drift-Ack-Growth: execute-phase.md — #3552: execute-phase handle_branching adds a pointer to execute-phase/steps/protected-branch.md for branching_strategy=none so the protected-branch check executes while keeping execute-phase.md within the ADR-857 Phase 6 margin ceiling (93400 bytes). 93392 bytes, 8 bytes inside the ceiling.
Emitted-Drift-Ack-Growth: ship.md — #3552: ship preflight step 3 now asks the same typed git.base-branch --is-protected predicate as execute-phase, binding IS_PROTECTED and warning without refusing execution or blocking the branching_strategy=none feature-branch offer; it degrades visibly (rather than silently reading an empty result as "not protected") when the query itself fails to run. 36841 bytes, well inside the XL cap (98304, tests/workflow-size-budget.test.cjs).

472f585f7c fix(#3726)!: require --confirm before milestone complete mutates (#3774)
* fix(#3726): require --confirm before milestone complete mutates

`milestone complete <version>` is a one-way door — ROADMAP.md and
REQUIREMENTS.md archived, every phase directory in the milestone MOVED,
STATE.md rewritten — and ran unconditionally on first invocation through
every invocation path, including `query milestone.complete <version>`,
whose `query` meta-prefix reads as a read-only namespace but performs no
filtering (#167's invocation-compatibility shim + #3243's dotted-form
normalization).

The gate lives on the destructive command itself, not on the `query`
prefix (the prefix is an intentional invocation mechanism, not a
permission boundary — restricting it would break dozens of shipped
workflow callers). Without --confirm and without --dry-run the command
now refuses via error() before reading anything beyond its arg checks,
so an unconfirmed invocation is a guaranteed no-op on disk. --dry-run
still previews with no confirmation needed and is now documented in the
usage block (it was only documented for the sibling archive-quick).
--force keeps its narrow meaning — bypassing the TRUNCATED-scope and
unstarted-phase guards — and does not double as the mutation opt-in.
--confirm follows the existing `phases clear --confirm` idiom in the
same module.

complete-milestone.md's two invocations pass --confirm (the workflow has
gathered explicit user intent by that step). Existing tests get
--confirm appended — pre-change behavior is exactly confirmed behavior —
and a #3726 regression block covers: refusal + full-tree byte-identity
on both invocation forms, --force not satisfying the gate, --dry-run
still passing without confirmation, and --confirm proceeding. The
refusal tests fail against pre-fix code (negative control run).

Fixes #3726

* docs(#3726): document the --confirm requirement in CLI-TOOLS and COMMANDS

Cross-AI review of the fix diff (codex, pre-create) caught three shipped
doc sites still instructing the now-refused bare invocation: the
CLI-TOOLS.md milestone-complete synopsis + flag table, and COMMANDS.md's
two guard-override instructions (`--force` alone now refuses without
--confirm). Localized CLI-TOOLS copies already lag the English synopsis
(no --force/--dry-run either) and follow the translation pipeline, not
this fix.

* chore(#3726): set changeset fragment pr to 3774

* test(#3726): confirm-gate CI repairs — QA scenario caller + growth ack

Two CI reds from the --confirm gate, both this branch's own misses:

- tests/qa/scenarios/milestone-rollover.json invoked `milestone complete
  1.0 --force` as a JSON arg-array fixture — a caller shape the test
  sweep (which grepped runGsdTools/runSdkQuery in tests/*.cjs) never
  enumerated. Adds --confirm; the scenario's boundary-crossing contract
  is otherwise untouched.
- complete-milestone.md's +420-byte --confirm note trips the
  emitted-attribution growth ratchet. Acknowledged as a #3726 append to
  the existing complete-milestone.md entry in
  3409-unreachable-guard-arms.json (two ack sources may never name the
  same path, per that fragment's own precedent).

Local: lint-emitted-drift-ack ok; loop-walk.qa 115/115 green sandboxed.

* docs(#3726): CLI-TOOLS.md guard-override sentences say --force --confirm

Review Major 1: the truncated-window and unstarted-phase guard paragraphs
still told the reader to "Pass `--force` to override", which now refuses
(--force alone does not satisfy the confirmation gate), while the flag
table 470 lines later said the opposite. Mirror the docs/COMMANDS.md pair
so the file no longer contradicts itself.

* docs(#3726): synopsis renders --confirm and --dry-run as alternatives

Review Nit 1: `milestone complete <version> --confirm [--dry-run]` read as
"a dry run still needs --confirm", the opposite of AC 3. Render the pair
as `(--confirm | --dry-run)` in the CLI-TOOLS.md synopsis and the usage
docblock, and let the flag rows carry the rule.

* test(#3726): pass --confirm in base-added milestone fixtures; re-file the growth ack

Rebase onto next (26 commits) surfaced three tests the gate now refuses:
the #3685 write-flag contract pair in tests/milestone.test.cjs and the
`milestone complete` boundary fixture in tests/state-contract.test.cjs
all invoke the command bare. Each now passes --confirm (a mutating run is
exactly what they assert on).

The +420 byte complete-milestone.md growth ack rode on
3409-unreachable-guard-arms.json, which #3078 swept from next as fully
spent — hence the modify/delete conflict. Re-filed under a fresh fragment
named for this issue, never resurrecting the swept one.

* test(#3726): pin the present-but-falsy arm of the confirmation gate

Review Minor 1: the boundary triple covered absent and present but not
present-but-falsy. The gate is an exact-token match, so --confirm=false
and --confirm=0 refuse today — pinned (canonical + query forms, whole
.planning/ tree byte-identical) so a future `=`-aware or prefix-matching
parser cannot silently turn --confirm=false into a confirmed run of an
irreversible command.

* test(#3726): drop --confirm from dry-run-only invocations

Review Nit 2: --confirm was mass-appended to 14 pre-existing --dry-run
invocations that never needed it, so each stopped standing as incidental
proof that a preview needs no confirmation. Reverted to the pre-PR form;
the dedicated AC-3 test carries the explicit assertion.

* docs(#3726): sync the localized CLI-TOOLS synopsis with the confirm gate

REQ-I18N-02 (docs/features/internationalized-documentation.md) requires
translations to stay synchronized with the English source. The four
localized CLI-TOOLS.md guides still advertised a bare
`milestone complete <version>`, which now exits 1. Render the English
synopsis verbatim — `(--confirm | --dry-run)` plus the `[--force]` and
`[--archive-quick]` flags the translations had also fallen behind on.

* test(#3726): drop --confirm from the remaining preview-only invocations

Round 2 reverted the --confirm appends on --dry-run-only invocations in
tests/milestone.test.cjs, but four more sat in two files the sweep missed:
tests/milestone-archive.test.cjs (three) and
tests/milestone-window-single-owner.test.cjs (one).

Each is a preview run whose whole purpose is to document that a preview
mutates nothing, so `--dry-run ... --confirm` contradicted the semantics
the test exists to pin. Dropping the token restores each as incidental
proof that a preview needs no confirmation; the dedicated AC-3 test keeps
the explicit assertion.

No assertion added, relaxed, or removed — the change is four tokens.

* chore(#3726): migrate the emitted-drift ack from a fragment to a commit trailer

#3954 (ADR-3942) moved emitted-drift acknowledgments out of
tests/emitted-drift-acks/ and into git commit trailers, and the fragment
directory no longer exists on next. The reason this PR's fragment carried
moves verbatim into the Emitted-Drift-Ack-Growth trailer on this commit;
the fragment file is removed rather than resurrected.

Emitted-Drift-Ack-Growth: complete-milestone.md — #3726: +420 bytes (40186 -> 40606). The archive_milestone step's two `milestone complete` invocations now pass the required --confirm flag (the command refuses to mutate without it — the archive is irreversible), with a note explaining the flag and pointing at --dry-run for previews. Deliberate runtime-loaded workflow text for the new gate, not converter drift.

* fix(#3726): name --confirm in the version-required refusal

The documented arg-discovery path (gsd-tools.cjs top-level usage: invoke
the command without args and the error lists what is required) stopped at
`version required for milestone complete (e.g., v1.0)` — one required
argument short. Discovering --confirm took a second round trip through the
gate. The refusal now reads `… — and --confirm to mutate`, pinned by a test
that also asserts the version-less invocation leaves .planning/ untouched.

* test(#3726): pin the milestone complete docs against a silent regression

The changeset is `type: Fixed`, which the docs-required lint exempts, so
nothing in CI would notice a later edit that reinstated the bare-`--force`
override prose or dropped `--confirm` from the synopsis. Four tests in
tests/milestone.test.cjs now pin: the synopsis line in docs/CLI-TOOLS.md
and its four localized mirrors; the `--confirm` flag row; both
guard-override instructions in docs/CLI-TOOLS.md and docs/COMMANDS.md,
by guard name (a substring match on each instruction's `--force
--confirm` text); and — as an identity ratchet over the
milestone-complete sections — every `--force` sentence or clause that
lacks `--confirm`, so a new bare instruction in its own sentence or
clause fails whatever its wording. Named residual: a bare instruction
spliced into the same clause as a compliant one coalesces with it and
passes the ratchet; the by-name pins are what keep the four known
instructions from losing the pairing that way. The file is registered
in scripts/docs-guard-registry.cjs so the pin runs on the PR that
changes those docs, not only after merge.

400db94e02 fix(#3894): quick path honors workflow.research_before_questions; key resolves from global defaults (#4047)
* test(#3894): research_before_questions must resolve globally and order quick.md (failing first)

* fix(#3894): quick path honors workflow.research_before_questions; key resolves from global defaults

Two layers, one key. The quick workflow ran its discussion phase
before its research phase unconditionally — neither quick.md nor its
steps ever read workflow.research_before_questions, though the key is
documented, schema-registered, /gsd-settings-writable, and honored by
/gsd-discuss-phase and /gsd-new-project. A gray-area answer given
without research is then written to <quick_id>-CONTEXT.md as a locked
decision downstream agents are told not to revisit — an evidence-free
choice made unfalsifiable (the reporter's #3714 misresolution).

- quick.md Step 4 now carries the same research-before-questions check
  the two honoring paths make: when enabled, research-phase executes
  before discussion-phase; false/unset keeps the written order. Both
  sections stay section-manifest gated.
- src/config-loader.cts forwarded workflow.post_planning_gaps from
  ~/.gsd/defaults.json but silently dropped this key — same file, same
  nesting, one resolved and one didn't. Now forwarded with the same
  flat + nested-alias fallback shape, added to the resolution-keys
  lockstep canary and the #3532 shadowed-warning set (nested alias
  reporting generalized over both keys).

Emitted-Drift-Ack-Growth: quick.md — #3894: +Step 4 ordering rule (the research-before-questions check the discuss-phase and new-project paths already make); a real behavioral gate, not incidental bloat.

* fix(#3894): review fold-ins — gate the CONTEXT.md reference, colon slash-forms

- quick/steps/research-phase.md directed the researcher subagent to read
  <quick_id>-CONTEXT.md under DISCUSS_MODE with no existence hedge — but
  under the new ordering (research BEFORE discussion) the file cannot
  exist yet when the researcher is dispatched. The reference now says
  read-only-if-present with the #3894 reason; the alignment purpose
  still applies on the default ordering.
- quick.md's new rule used the hyphen slash forms (/gsd-discuss-phase,
  /gsd-new-project); source artifacts under gsd-core/workflows must
  author the colon form the install-time converters key on — the same
  file already uses /gsd:new-project and /gsd:quick elsewhere.

* docs(#3894): planning-config row names the flat CONFIG_DEFAULTS alias

config-field-docs requires every CONFIG_DEFAULTS key to appear in the
doc; the row documented the canonical namespaced form only. Adds the
same alias sentence post_planning_gaps's row carries, plus the #3894
quick-path note.

* test(#3827): new-mode routing approval gate before roadmapper (failing first)

* fix(#3827): new-mode routing gate — classify approval no longer authorizes scaffold writes

The route_new_mode step delegated to gsd-roadmapper (PROJECT.md,
REQUIREMENTS.md, ROADMAP.md, STATE.md creation + commit) with no gate:
the discovery gate approved classification only, and the zero-conflict
branch said 'proceed to routing silently'. Merge mode previews its diff
and gates via approve-revise-abort; new mode now shows the exact
destinations and requires Create planning setup | Keep synthesized
intel only | Abort, per the skill contract's routing-gate requirement.
The keep-intel-only choice is the analysis-only path the issue asks
for: no roadmapper, no destination writes, intel preserved; finalize
labels it 'new (intel only)' and points at /gsd:new-project instead of
plan-phase. Ambiguous gate answers re-ask once, then treat as Abort —
never infer Create. Zero-conflict wording is mode-aware: silence about
conflicts is not authorization to write.

Emitted-Drift-Ack-Growth: ingest-docs.md — #3827: +routing gate display block, AskUserQuestion contract, three disposition branches (incl. the intel-only no-write path), ambiguous-answer rule, intel-only finalize line, mode-aware zero-conflict pointer; a real behavioral gate, not incidental bloat.

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3914

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

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

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

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

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

Refs #3914

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3914

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

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

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3914

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

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

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

So the epic added FOUR guards, not three.

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

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

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

Verification runs on the remote runner.

* test(#3797): the roadmapper must follow one write-first contract

The roadmapper contradicted itself: role blurb, output format, and
completion checklist described an approve-first flow while its execution
flow said "Write Files Immediately" with reactive-only revision (#3797).
The approval gate belongs to the ORCHESTRATOR — both callers read the
written ROADMAP.md, present it, and gate on approval (with an auto-mode
bypass a subagent cannot host) — so write-first is the contract.

All approve-first text now describes the write-then-return reality, the
old "Draft Presentation Format" (whose ## ROADMAP DRAFT header matched no
orchestrator branch) is folded into the ## ROADMAP CREATED structured
return as a preview block, and the duplicate checklist lines are merged.
A structural guard pins the single contract.

dd4f179672 feat(#3970): per-task external-tracker content-resolution seam (#4000)
* feat(#3970): per-task external-tracker content-resolution seam

Implements ADR-3646 (Phase 1, #3970): a `<task tracker-id="...">` attribute
plus a new optional `taskContentResolver` capability-manifest field let a
capability resolve a task's action/verify/acceptance-criteria/read_first/done
content from an external issue tracker instead of PLAN.md's inline body.

- src/plan-document.cts: parses the `tracker-id` attribute into `PlanTask.trackerId`
- src/task-content-resolution.cts: new leaf module — split/find/build/resolve,
  with a hard-halt (throw) contract on ambiguous/failed/timeout/malformed
  resolution, never a silent fallback to possibly-stale inline text
- src/task-command-router.cts: new `task resolve-content --plan --task-id --raw`
  CLI verb wiring the module into a real process exit code
- gsd-core/bin/lib/capability-validator.cjs: validates the new
  `taskContentResolver` manifest field (feature-role only, cross-capability
  trackerPrefix uniqueness)
- gsd-core/workflows/execute-plan.md, gsd-core/references/loop-hook-dispatch.md,
  docs/reference/capability-manifest.md: wire the seam into the per-task loop
  and document it as a new `execute:task` point outside the existing
  contribution/step/gate vocabulary (unconditional in autonomous mode)

Closes #3970

* fix(#3970): gate checkpoint tasks out of content resolution, close trackerPrefix grammar parity gap, cover path-traversal guard

Standards/Spec code-review pass on the task-content-resolution seam (ADR-3646
Phase 1) found three defects:

1. execute-plan.md's task-content-resolution bullet fired on any
   tracker-id-bearing task with no check that it wasn't type="checkpoint:*",
   contradicting ADR-3646 Decision 1 (a checkpoint task must never enter
   resolve-content). plan-document.cts already parses trackerId: null
   unconditionally for checkpoint tasks; only the workflow prose needed the
   fix, so the bullet now explicitly excludes checkpoint tasks.

2. task-content-resolution.cts's parseResolverDeclaration accepted any
   non-empty trackerPrefix with no grammar check, while capability-
   validator.cjs's KEBAB_RE enforces kebab-case at install time — a
   Generative Fix Divergence gap. Added the same grammar (as a literal
   regex, documented as intentionally not shared across the .cts/.cjs build
   boundary) plus a parity test asserting the two surfaces agree across a
   valid/invalid trackerPrefix table.

3. task-command-router.cts's routeResolveContent path-traversal guard on
   --plan had zero test coverage. Added a test exercising a
   ../../../etc/passwit-shaped path and asserting the USAGE rejection names
   the offending path.

* fix(#3970): sanitize resolver diagnostics and cap resolver timeoutMs

Two findings caught by an isolated security-review pass on the task
content resolution seam:

- ResolverFailedError/ResolverMalformedOutputError embedded raw,
  unsanitized subprocess stderr/stdout (attacker/model-influenced via
  the tracker-id argv token) into .message. A hostile or buggy resolver
  could smuggle a newline plus a forged "Error: " line, or terminal
  escape sequences, into a diagnostic io.cjs's error() writes verbatim
  to stderr. Fixed at the constructor (task-content-resolution.cts) via
  io.cjs's existing formatDiagnosticToken(), so every caller of
  resolveTaskContent gets a safe .message by construction.

- capability-validator.cjs's validateTaskContentResolverFields had no
  upper bound on taskContentResolver.invoke.timeoutMs, letting a
  manifest declare an effectively unbounded value and defeat the
  "bounded subprocess" design intent. Added a 120000ms ceiling specific
  to this field, without touching the shared isPositiveIntegerMs()
  helper (still used unbounded by the reviewer lane's timeoutFloorMs
  and probe timeoutMs).

  ExitError's own .message. io.cts's error() (ADR-3889) writes its
  human-readable message to fd 2 via writeAllSync and then throws a bare
  `new ExitError(1)` with no message argument — by design, so the
  exception carries no duplicate text and the thrown ExitError's message
  defaults to "process exit 1" (cli-exit.cts's ExitError constructor).
  Root cause was the test, not the source: task-command-router.cjs's
  outside-project-scope rejection already calls error() correctly and the
  diagnostic text is genuinely emitted, just on fd 2, not on the
  exception. Fixed the test to capture fd-2 writes (mirroring
  tests/estimate-calibrate.test.cjs's runCalibrateExpectError and this
  same file's own captureStdout for fd 1) and assert against the captured
  stderr text instead of err.message. This was masked locally because a
  manual `node -e` sanity check that only inspects the caught exception's
  .message cannot see what the real node:test run actually failed on.

Emitted-Drift-Ack-Growth: execute-plan.md — adds the ADR-3646 task-content-resolution bullet and checkpoint-exclusion caveat to the per-task execute loop; a real behavioral prose addition, not incidental bloat.

* test(#3786): the quick planner constraints must carry a mutable-scope authority rule

* fix(#3786): authorize mutable scope from live observation only in the quick planner

The quick planner could commit HISTORICAL scope as authorized edit or
verification scope before any live observation of the mutable state: a
minimized probe used cached PR-diff paths (65 of them, "pending
replacement") or broadened verification to the PR integration surface in
2 of 3 trials (#3786). One explicit authority requirement reduced that
to 0 of 3.

The new planner constraint authorizes mutable-state scope ONLY from a
live observation made at planning time (for conflict resolution, the
fresh merge index via git diff --name-only --diff-filter=U) or keeps
files/verify CONDITIONAL on it; historical STATE.md entries, recovery
notes, and cached PR/base diffs may guide investigation only. A
structural guard pins the rule in the shipped constraints block.

* test(#3782): step 1.6 must segment verification debt by the archived stamp

* fix(#3782): segment verification debt by the archived_milestone stamp in progress step 1.6

progress.md step 1.6 read the cross-population summary.total_items as
current-milestone debt while claiming the whole query respects milestone
boundaries. The active tree is milestone-filtered; archived trees are
deliberately unfiltered (each result stamped archived_milestone), so a
healthy current milestone presented six shipped milestones' still-open
items as CURRENT debt on every /gsd-progress run (#3782).

Step 1.6 now computes CURRENT_DEBT/ARCHIVED_DEBT via jq selects on the
stamp, tracks archived_debt separately (visible with its own labeled
header — segmented, never hidden), corrects the scoping claim, and
unwraps the CLI's @file: large-payload redirect before jq so counters
cannot silently read 0. A structural guard test pins the segmentation.
parse_gap_files stays deliberately cross-population.

Emitted-Drift-Ack-Growth: progress.md — #3782: +1406 bytes — step 1.6 gains the CURRENT_DEBT/ARCHIVED_DEBT segmentation jq, the @file: unwrap, and the archived-visibility paragraph; parse-gap paragraph reworded to match

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3912

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3912

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

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3912

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

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

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

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

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

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

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

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

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

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

Verification runs on the remote runner.

Refs #3912

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

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

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

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

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

d98b55562c enhance(#3910): the raw terminator is banned by construction (#3980)
* enhance(#3910): move the last src/ terminators onto the seam

Phase 6 bans the raw terminator by construction, which it cannot do while
violations stand. A census found 12 sites the rule would flag; nine of the ten
unsanctioned ones were owned by no phase of the epic at all — a coverage hole
in the decomposition, since P0-P2 are infra, P3 the gate modules, P4 the
scanners, P5 the fragments, P7 the hooks, P8 io.cts, and P6 itself only adds
the rule. `src/**/*.cts` now holds exactly 2 raw exits, both inside
`terminateNow`, the single sanctioned site.

`io.cts`'s `error()` is the interesting one. It was first called substantive on
"dozens of callers, contract risk" — asserted, not measured, and the
measurement refuted it: 289 call sites, zero inside a try whose catch would
swallow a throw. The real obstacle was structural instead: `terminateNow`
cannot emit exit 1, because ADR-3889 §1 makes 0 and 1 unallocatable and
`nameForExitCode(1)` throws. So the only route is `ExitError` under `runMain`,
which sets exitCode and writes stderr only when the error carries a user
message — keeping the existing stderr write and throwing a message-less
ExitError is observably identical.

That census was still too narrow, and running the CLI proved it. It asked
whether the CALL sits in a try/catch; the two regressions that surfaced were
interceptors elsewhere on the stack:

- `command-routing-hub.cts`'s `dispatch()` swallowed the ExitError into a
  HandlerFailure, so the caller emitted a duplicated, wrong stderr line on
  every Hub-routed path. It now rethrows ExitError explicitly — the same shape
  `gsd-tools.cjs` already used at two dispatch sites, so this follows an
  established idiom rather than inventing one.
- the profile-pipeline router's deliberately un-awaited `.catch(e => error(...))`
  turned an ExitError rejection into an uncaught exception; it now mirrors
  runMain's handling.

`edge-probe` and `ui-consideration-probe` gained `runMain` wrappers because
probe-core's new throwing default would otherwise have escaped them.

A follow-up sweep of every dispatcher — 19 command routers, the Hub, the
gsd-tools dispatch seams — found no further swallowing catch. The admitted
bound: ~1260 non-rethrowing catches repo-wide were scanned structurally but not
individually classified. Both real regressions were found by execution, not by
reading, so the suite is the detector that matters here.

`gsd-tools.cjs:253` stays a raw exit deliberately: it is the ensureRuntimeBuild
bootstrap, which runs before cli-exit is required, so the seam does not yet
exist. It needs a second allowlist entry, which means #3910's "single allowlist
entry" criterion is unachievable as written.

Verification runs on the remote runner.

Refs #3910

* enhance(#3910): ban the raw terminator by construction

Adds local/require-registered-exit and registers it on all four globs:
src/**/*.cts, scripts/**/*.cjs, hooks/**/*.js, gsd-core/bin/**/*.cjs.

Registering on the .cts glob is load-bearing, not redundant — the emitted .cjs
mirrors are globally eslint-ignored, so a rule registered only on the emitted
globs is blind to the sources. That is the #3496 lesson, and it is how the
previous guard became invisible: n/no-process-exit was 'error' in one block yet
fired zero times on all three surfaces that mattered.

The dead n/no-process-exit: 'off' block for hooks is deleted in the same PR.
Phase 7 migrated every hook, so the exemption now protects nothing.

Two allowlist entries, not the one #3910 anticipated. terminateNow's body is
detected STRUCTURALLY — a process.exit lexically inside a function of that name
— rather than by a path and line number that rots. The second is
gsd-tools.cjs's ensureRuntimeBuild bootstrap, an inline disable with its reason
at the call site: it runs before ./lib/cli-exit.cjs is required, so the seam
does not exist yet and no migration is possible. #3910's 'single allowlist
entry' criterion is therefore unachievable as written, and is amended with the
measurement rather than quietly missed.

The rule is proven able to FAIL, per glob: four positive controls, one for each
registered glob. A guard that cannot be shown to fire is not a guard. Four
matching negative controls pin process.exitCode as never-flagged — conflating
it with process.exit is what inflated this epic's original census 2x. An
allowlist case and a near-miss (same shape, different function name) fix the
structural detection in place.

Verification runs on the remote runner.

Refs #3910

* fix(#3910): stop the detached catch from throwing, and scope the allowlist

Review findings, one of them a regression the previous fix introduced.

_handlePipelineRejection called error() from inside a DETACHED .catch().
error() now throws, so that throw became an unhandled promise rejection — and
on Node >=15 with --unhandled-rejections=throw, Node dumps a raw stack trace
with absolute paths on top of the clean Error: line. That was impossible before
this branch, because process.exit(1) terminated synchronously before any
rejection machinery could observe it. The handler now writes byte-identical
stderr itself, in both plain and --json-errors form, and sets exitCode in
place. This was the THIRD interceptor found, and like the first two it surfaced
by running the CLI rather than by reading code.

The rule's terminateNow allowlist had no path constraint, so any function
anywhere named terminateNow across all four globs inherited it. It now requires
the structural nesting check AND a cli-exit.cts basename — still no line
numbers to rot.

The four per-glob positive controls only varied a filename inside RuleTester,
which never resolves eslint.config.mjs. Since the rule is filename-agnostic,
all four exercised identical logic and none proved the rule was WIRED — this
epic's own failure mode. A registration test now asserts the rule resolves for
a real path in each glob, and it is proven able to fail: removing one glob's
registration flips the resolved value from [2] to undefined.

Three evasions the rule cannot catch (computed member, aliasing, .call/.apply)
are documented in its header and pinned by tests, labelled as known limits
rather than endorsed, so a future change that starts catching them is a
deliberate diff.

Refs #3910

* docs(#3910): document the raw-terminator ban

Reference and Explanation via a new docs/features fragment (FEATURES.md is
generated from it, not hand-edited). How-To:
docs/how-to/resolve-a-raw-terminator-finding.md, indexed from docs/README.md —
a contributor whose code trips the rule picks among three replacements by
surface (runMain/ExitError for a CLI path, terminateNow for a hook,
process.exitCode where the process should drain), and needs to know why
process.exitCode is correct and never flagged, since conflating the two is what
inflated this epic's original census 2x.

The page also names the three patterns the rule cannot catch and says plainly
that using one to dodge it is a review finding, not a fix — documenting them
without that sentence would read as a sanctioned workaround.

docs/INVENTORY.md deliberately untouched: eslint-rules/ is not a tracked family
in the manifest (verified — a regen produced a zero diff), so a hand-written row
would desync the table from the family it claims to belong to.

Refs #3910

* fix(#3910): a catch that sniffs the message swallows an ExitError

The remote run returned 41 failures, and one of them was a live production
regression rather than a test artifact.

`cmdMilestoneComplete`'s unstarted-phase guard re-threw only when
`e.message.startsWith('Cannot mark milestone complete:')`. `error()` used to
`process.exit(1)`, uncatchable, so the guard always fired. It now throws an
ExitError carrying no message, the string test fails, and the ExitError was
silently swallowed — the guard stopped blocking milestone completion entirely.
Proven against the real CLI: pre-fix, a milestone with an unstarted phase
archived at exit 0; post-fix it is blocked at exit 1 with the intended message.

That is a guard that silently stopped guarding, which is this epic's thesis
appearing inside the phase meant to enforce it. Worth stating plainly: an
earlier census DID examine this site, saw a `throw e`, and classified it as
rethrowing. It was wrong — the rethrow is conditional, and a conditional
rethrow on an inspected message is indistinguishable from an unconditional one
unless you read the predicate.

So the class was swept rather than patched where it was tripped over. An AST
census of every CatchClause across src/, gsd-core/bin/ and scripts/ found 38
conditional rethrows. Two more had the same defect and are fixed the same way:
`config.cts`'s `'No config.json'` sniff and `gsd-tools.cjs`'s
`e.name === 'WindowsError'`. The remaining 25 are provably unreachable — every
one wraps a bare fs, YAML, manifest-require or git-exec primitive that cannot
throw ExitError — and two were scanner false positives, both explained. Each
fix is an unconditional `instanceof ExitError` rethrow placed BEFORE any
inspection, matching the idiom command-routing-hub and gsd-tools already used.

Residual bound, stated rather than implied: zero known-reachable unfixed sites,
contingent only on error() never later being called inside one of those 25
primitive try blocks.

The remaining failures were harness artifacts, and the harnesses were corrected
to the new contract rather than the assertions weakened. Tests that mocked
`process.exit` to observe termination now catch ExitError and assert its code;
tests parsing stderr as a single JSON object still assert exactly that, with
their ad-hoc `node -e` scripts wrapped in runMain so it is true. milestone and
phase-resolution-parity needed no test change — they were correctly written
against the real bug and are what caught it.

Verification runs on the remote runner.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refs #3951

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

2ea5efc151 enhance(#3911): hooks declare their crash policy (#3960)
* enhance(#3911): give hooks an exit seam that needs no build

ADR-3889 Phase 7 foundation. The 19 shipped enforcement hooks hold 91 of the
epic's 128 terminators and cannot reach `terminateNow` today.

The obvious route — requiring `gsd-core/bin/lib/cli-exit.cjs`, as
gsd-agent-isolation-guard.js already does for two other modules — is rejected.
That precedent carries its own warning (#3582): those files are tsc output,
gitignored and absent on a raw plugin-marketplace or git-clone install, so the
hook must first call ensureRuntimeBuild() to self-heal. Making the module a
hook needs IN ORDER TO TERMINATE depend on a build inverts the dependency, and
its failure mode is precisely the fail-open this phase exists to remove: a
guard that cannot terminate cannot deny. `lint-hooks-runtime-build-seam`
already encodes that concern, and Design B would have had to add an
ensureRuntimeBuild() call to all 19 hooks to satisfy it.

So `hooks/lib/` becomes a third emit location for cli-exit and a fifth for the
registry, preserving the invariant `src/cli-exit.cts`'s own header states: it
imports nothing but node:fs and its sibling registry, and the generator
dual-emits that sibling alongside each copy so a relative require resolves next
to whichever copy loaded it. Shipping needed no change — build-hooks.js already
declares HOOKS_SUBDIRS_TO_COPY = ['lib'].

Proven, not asserted: the two files are copied into an otherwise-empty tmpdir
and a child process requires them and terminates — PASS exits 0, HOOK_DENY
exits 2 with the payload on both stdout and stderr. That test fails the moment
the hooks copy gains a require reaching outside hooks/lib/.

Also fixed inline: the registry's fifth target let any `--write` test overwrite
the real committed hooks/lib/exit-code-registry.js, because the test helper
derived only three of the other output paths. It now redirects all five, and a
regression test asserts every committed artifact is byte-identical after a
redirected write.

Install-tree goldens pick up the two new shipped paths across 11 runtimes —
insertions only, no removals. lint:ci was green while they were stale, so this
was found by regenerating rather than by a gate.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): declare a crash policy, and migrate the write guard

Adds `hooks/lib/hook-exit.js` — the hook-facing vocabulary over `terminateNow`,
hand-written because the cli-exit copy beside it is generated:

  allow(payload)          exit 0
  deny(payload, stderr?)  exit 2
  crash(onCrash, payload) whichever the hook DECLARED

`crash()` takes the policy as a required argument with no default, which is the
whole mechanism: fail-open by accident stops being expressible. A hook must
name ALLOW or DENY at the call site, and an unrecognized value terminates
INTERNAL rather than guessing. Fail-open stays legal; fail-open by omission
does not.

`gsd-write-guard.js` is the first hook migrated, all 12 sites, and it exposed a
gap in the seam. `terminateNow`'s doc comment justified its fd-2 write by
citing this hook's `emitBlock` — but modeled it as sending the same bytes to
both streams, when `emitBlock` actually sends full JSON to stdout and only the
bare `reason` string to stderr, because Kimi's hook bus feeds stderr verbatim
back to the model. Migrating as written would have turned a readable sentence
into a JSON blob for Kimi-backed agents.

#3911 requires both "all 19 hooks terminate through terminateNow" and "no
hook's effective default changes". Those are jointly satisfiable only by
teaching the seam to carry a distinct stderr payload, so `terminateNow` gains
an optional third argument: omitted, behavior is byte-for-byte what it was; a
string is written raw, which is exactly the Kimi case. The doc comment's
inaccurate claim about emitBlock is corrected in place.

Proven rather than asserted: the pre-migration file is reconstructed from HEAD
and driven with the same catastrophic-shrink payload as the migrated one —
exit code, stdout and stderr all byte-identical.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): all 19 hooks terminate through the seam

Migrates the remaining 18 enforcement hooks onto allow/deny/crash. An AST walk
now reports zero `process.exit(` call sites across every `hooks/*.js` — down
from the 91 the census measured.

Each hook with an outer catch declares its policy once, at module top, with the
reason that policy is right for that specific guard: a read guard that cannot
scan must not block the read; a statusline that renders every prompt must
degrade rather than crash; an injection scanner must not retroactively block a
result already returned. Those sentences are the deliverable — they are what
turns fail-open-by-accident into fail-open-on-purpose. No hook's effective
default changed.

Wiring exposed two defects, both fixed here rather than noted.

A SECOND stdout/stderr-splitting site turned up in `gsd-workflow-guard.js`'s
`emitForceAddBlock`, matching the pattern already known from the write guard —
full JSON to stdout, bare reason to stderr for the Kimi bus. It uses the
`stderrPayload` argument added in the previous commit, which is now carrying
its second real caller rather than one special case.

More seriously, `terminateNow` emitted both streams inside ONE try, so a
payload that failed to serialize aborted before the stderr write ever ran. The
two windsurf guards write nothing to stdout on a block and only a reason string
to stderr, so `deny(undefined, reason)` exited 2 with EMPTY stderr — a deny
that silently loses its reason, which is the exact "fails with success" class
this epic exists to close. The streams are now emitted independently, each with
its own guard, and `undefined` means "nothing to write for this stream" rather
than an error. Regression tests inject a throwing write on one fd and assert
the other still receives its payload; they fail against the single-try version.

Byte-identity was proven per hook, not assumed: each pre-change file is
reconstructed from HEAD and driven side by side with the migrated one across
its normal path, its deny path, malformed stdin and empty stdin — exit code,
stdout and stderr compared.

Verification runs on the remote runner.

Refs #3911

* enhance(#3911): harden the three shell hooks, and pin every hook's policy

`gsd-phase-boundary.sh`, `gsd-session-state.sh` and `gsd-validate-commit.sh`
gain `set -euo pipefail`.

The expected hazard did not materialize, and that is worth recording: every
intentionally-non-zero command in all three is already the condition of an
`if`/`elif`, which `set -e` never fires on, and none of them reads a
possibly-unset variable or pipes through a grep that may legitimately match
nothing. No `|| true` guards were needed. Each hook was still checked
command-by-command before the flags went in rather than after.

Twenty-one before/after cases across the three hooks — disabled and enabled,
planning and non-planning, missing STATE.md, malformed JSON, the Kimi payload
shape, quoted and unquoted `-m`, valid and over-long Conventional Commits —
all match on exit code, stdout and stderr.

The hardening is shown to actually fire, not merely added: with a stubbed
`node` that fails at the JSON-emit step, phase-boundary and session-state go
from silently exiting 0 with empty stdout to failing visibly with the error
surfaced. No such case could be constructed for `gsd-validate-commit.sh`,
whose every statement already sits inside an if-condition — recorded as
unproven rather than claimed.

`tests/hooks-crash-policy.test.cjs` adds the per-hook coverage the issue asks
for, table-driven over all 19 hooks rather than 76 hand-written cases: normal
allow, deny where a deny path exists, crash-honors-the-declared-policy, and an
unclosed-stdin case — the one `process.exitCode` structurally cannot serve. The
deny assertions encode each hook's ACTUAL stream split rather than a uniform
shape, since four of the six deliberately differ. A drift guard enumerates
`hooks/*.js` and fails if a terminating hook is ever added without a row.

Writing those tests surfaced two hooks that emit a block decision in their JSON
body and exit 0. Both were checked rather than assumed, and neither is a
fails-with-success: `gsd-read-injection-scanner.js` is PostToolUse, where the
tool has already run and exit 2 has no meaning, and `gsd-cursor-subagent-start.js`
follows Cursor's JSON-body protocol. They are deliberately left alone — a
mechanical sweep to `deny()` would have broken exactly these two.

Verification runs on the remote runner.

Refs #3911

* fix(#3838): the commit validator says when it could not validate

#3911 claims to subsume #3838. Measurement said otherwise, so this closes it
for real rather than by assertion.

`set -euo pipefail`, added earlier on this branch, does NOT fix #3838: bash
exempts a command used as an `if` condition from `set -e`, and all three of the
hook's swallow-and-pass sites are exactly that shape. Verified against the
hardened hook with a node shim that fails only the classifier call — a
non-conforming commit still exited 0 with empty stdout AND empty stderr,
indistinguishable from "your commit conforms". That is the defect verbatim.

All three sites named in #3838 now capture the real exit status instead of
consuming it as a condition, and each distinguishes its genuine negative from
"could not run":

- the classifier: 0 = is a git commit, 1 = genuinely not one, anything else =
  could not classify. Its `node -e` now wraps the require and the call in
  try/catch and exits 3 on a throw, so a broken require chain can never be
  mistaken for `isGitSubcommand` legitimately returning false — which is the
  arm that matters, since `token-scanner.cjs` is a gitignored build artifact
  and a fresh checkout lands there.
- the opt-in config read and the JSON command extraction get the same
  treatment.

On "could not run" the hook emits a diagnostic to stderr naming which check
failed and why, then exits 0. The issue confirms this is safe — it is a
PreToolUse hook, so stderr does not disturb the JSON protocol — and ranks it
the smallest sufficient fix. The gate still fails open, but it can no longer do
so silently, which is the whole complaint: a validator that disables itself
quietly costs more than one that is absent, because it is trusted.

Both controls are unchanged and pinned by tests: a conforming commit still
passes silently, a non-conforming one still exits 2 with its existing block
payload. The defect test asserts stderr is non-empty and names the failure; it
fails against the pre-fix hook.

Verification runs on the remote runner.

How-To: docs/how-to/declare-a-hook-crash-policy.md, indexed from docs/README.md
— a hook author now has to choose and declare a crash policy, which is more
than one step and crosses into which harness protocol their hook speaks. It
covers allow/deny/crash, writing an ON_CRASH reason that is actually useful,
when a deny needs a distinct stderr payload, the two hooks whose harness reads
a JSON-body decision and must NOT use deny(), and what to do when a check
cannot run at all — with #3838 as the worked example.

* test(#3911): prove the seam actually ships, and stop hand-rolling temp cleanup

Two review findings.

The acceptance criterion 'hooks/dist/** stays in parity via the build seam
(lint:hooks-runtime-build-seam)' was misstated and unmet: that lint checks
something else — that a hook requiring a compiled gsd-core/bin/lib module also
calls ensureRuntimeBuild(). Nothing exercised that the three new hooks/lib
files reach hooks/dist/lib at all. That gap is not theoretical: #770 is a
recorded ship-blocking bug where a new hook never shipped because a copy list
missed it. The suite now builds dist through the repo's own ensureBuiltHooks(),
byte-compares each shipped copy against its source, and spawns a child that
requires the SHIPPED dist copy and denies — which is what catches a copy that
exists but cannot resolve its sibling registry.

gsd-validate-commit.sh hand-duplicated mktemp/run/rm three times; one idempotent
trap on EXIT replaces them, guarded so cleanup cannot alter the exit status.
Behavior-neutral across five cases, with temp-file counts taken before and
after each run.

Refs #3911

* fix(#3911): stage transitive hook lib requires, not just one level

The remote run returned 7 failures across 3 real causes.

The important one is a PRODUCTION bug this phase exposed rather than caused.
`writeCursorHooksJson` scanned each hook script for `./lib/X` requires exactly
one level deep and never re-scanned the lib files it staged for their own
sibling requires. Nothing had a transitive lib dependency before, so the gap
was invisible. Adding hook-exit.js -> cli-exit.js -> exit-code-registry.js
made real Cursor installs ship a bundle that dies at require time with
MODULE_NOT_FOUND. It now walks to a fixed point, and a real installed Cursor
hook runs to completion.

The staging harness in shared-hooks-dir-resolution hand-copied its fixture, so
the injection scanner crashed at require time and its exit-1 was being read as
a policy decision. Migrated to copyScriptWithDeps, which walks the require
graph — the repo's recorded rule for this class, since adding another
copyFileSync keeps it alive for the next person.

The missing-lib-source test in cursor-hook-workspace-roots hardcoded which lib
file it expected to be named in the abort message; the same throw now fires for
a different file first. Its assertion is unchanged in substance — staging still
must abort rather than ship a broken hook — only the name is no longer pinned.

The last one was my own test asserting an uppercase reason code. Measured
against origin/next: the pre-change hook emits the same lowercase
'config_unreadable', so the test was wrong, not the migration. Corrected to the
real value rather than making the code match the test.

Verification runs on the remote runner.

* chore(#3911): regenerate the cursor install-tree golden

The staging fix means a Cursor install now correctly carries the two
transitive lib files it was silently missing. Additive only — no path was
removed. The golden diff is the evidence the packaging defect was real.

* fix(#3911): a git probe that timed out is not a negative

A macOS CI lane failed three deny cases at 2084ms, 2112ms and 2177ms — just
past the 2000ms budget these hooks give their git probes. The three that passed
took 72ms, 595ms and 651ms. Under shard contention `git rev-parse` overruns,
the hook reads the non-zero result as "not a git repo", and allows with exit 0
and empty stdout AND empty stderr. Under load, the guards silently stop
guarding. That is ADR-3889's thesis exactly, sitting inside the security hooks
this phase is about.

The repo had already recognized the class in one place — gsd-cursor-subagent-start.js
fail-closed-denies on `git_timed_out` (#3045) — but nowhere else.

`hooks/lib/git-probe.js` classifies a probe's outcome, distinguishing a real
non-zero exit from ETIMEDOUT, a signal kill, and a spawn failure, rather than
folding all four into `status !== 0`. Three guards route their eight git probes
through it.

The resolution is the same shape #3838 took, and the same one that issue
endorsed as smallest-sufficient: fail open, but loudly. **No exit code changes
on any path** — a developer on a loaded machine is still not blocked, which
keeps #3911's declaration-pass contract intact for exit codes. What changes is
that the hook now says on stderr which probe could not answer, instead of
presenting silence as a clean verdict.

Scope was checked across every hooks/*.js, not just the three that failed:
gsd-agent-isolation-guard spawns no git; gsd-statusline's two probes gate only
a cosmetic display segment, not an allow/deny decision, and are left alone.

The C2 deny assertion was a real-race test — it demanded exit 2 while a slow
git legitimately yields 0. It now requires the hook to either deny, or allow
with a diagnostic naming the probe that could not run; a silent allow still
fails, so the assertion is not vacuous. A deterministic regression stubs git on
PATH to sleep past the budget rather than waiting for load to reproduce it.

Verification runs on the remote runner.

Refs #3911

* test(#3911): a PATH shim cannot intercept the hooks' git spawn on Windows

The deterministic timeout regression stubbed git on PATH and asserted the
guard reports rather than silently allows. It passes on Linux and macOS and
failed on Windows in 83ms and 176ms — the stub was never invoked at all.

Mechanism: the hooks call spawnSync('git', args) with no shell:true, so on
Windows CreateProcess resolves git.exe only and never a PATH .cmd shim. The
git.cmd branch could not have worked and is removed rather than left implying
a Windows path that does. Adding shell:true to the hooks to serve a test would
change product behavior and widen an injection surface, so the case is skipped
on win32 only, with the mechanism written into the skip reason so a future
reader does not 'fix' it that way.

Linux and macOS keep the coverage, and macOS is where the underlying fail-open
was actually caught.

03b7125293 enhance(#3909): a probe that could not run no longer asserts a verdict (#3944)
* test(#3909): failing-first suite for the fabricated probe fallbacks

Binds the four fabrication sites found by executing the surfaces (ADR-3889
failure class (c)), each with a positive control so an over-firing fix goes red:

- the blocking api-coverage.verify-pre gate certifying "no external-API
  integration" from a zero-byte phase scope
- the assumption-delta query route scanning an unresolvable phase section as
  the empty string and reporting it as an examined negative
- both capability fragments' probe fallbacks, which append a fabricated
  verdict rather than replacing, and fire on the legitimate exit-1 negative

Verification runs on the remote runner.

Refs #3909

* enhance(#3909): a probe that could not run no longer asserts a verdict

ADR-3889 Phase 5. Four sites turned a failed or unexamined probe into a
confident negative; each now reports what it could not establish.

- check api-coverage.verify-pre: a phase with no plan body and no roadmap
  section ran detection over zero bytes and PASSED the blocking seal gate,
  certifying "no external-API integration" from input it never read. It now
  holds with scope_unavailable. The discriminator is bytes examined, never
  signals found, so a phase whose plans are real and simply carry no API
  vocabulary passes exactly as before.
- query assumption-delta scan: an unresolvable phase section was scanned as
  the empty string and reported as an examined negative. It now returns
  {skipped, reason: phase_unresolved}, still at exit 0 — an ADR-2980 degraded
  result in the payload, leaving the gsd-tools exit projection to P8.
- both capability fragments: `|| echo '{"detected":false}'` appended rather
  than replaced, and fired on the legitimate exit-1 negative, so a correct
  answer and an honest skip both arrived as two concatenated objects. They now
  keep the probe's own payload and manufacture only an explicit
  probe_unavailable skip when the probe produced nothing at all.

Every registered outcome is more restrictive on a blocking gate, so this can
turn a false green red and never a red green.

Docs: FEATURES 156, CONFIGURATION (both keys), references/api-coverage.md
seal-time outcome table, and a new how-to for the reason-code vocabulary.

Verification runs on the remote runner.

Closes #3909

* test(#3909): correct the stale unknown-phase assertion

`unknown phase → detected:false, no throw (graceful)` scanned phase 999
against a two-phase roadmap and asserted `detected === false`. That pinned
the fabrication as intended behavior: the phase does not exist, so the
detector was handed the empty string and its "no core assumption changed"
answer described nothing that was ever read.

It now asserts the skipped-with-reason shape. The graceful-degradation
contract the test was actually protecting — the query succeeds and does not
throw on an unknown phase — is unchanged.

Found by code review, not by the author.

Refs #3909

* docs(#3909): author the FEATURES entry in its generator source

`docs/FEATURES.md` is generated by `scripts/gen-features.cjs` from the
per-feature fragments in `docs/features/`. The API-coverage entry was edited
in the generated file, so the next regeneration silently dropped it.

The text now lives in `docs/features/api-coverage-gate.md` and
`docs/FEATURES.md` is regenerated from it, leaving the shipped file
byte-identical and its content actually derivable.

Caught by `lint:generated-sync`.

Refs #3909

* test(#3909): bind the skip to "not found", and pin the discriminator

The first verification run went red on one case, and the case was wrong
rather than the code.

`getRoadmapPhaseWithFallback` returns `null` for an unknown phase and for a
missing ROADMAP.md, but for a section whose body is whitespace-only it returns
the heading line alone — which is not empty. So a body-less section WAS found,
and reporting `detected:false` over its heading is a real negative, not a
fabrication. The test had assumed the resolver yielded `''` there.

Correcting the test rather than the resolver keeps `skipped` bound to the
distinction the issue asks for — found versus not found — and avoids diverging
`assumption-delta scan` from `roadmap.get-phase`, which the fragment documents
as sharing one resolver.

Also adds the seeded property the test matrix had promised: for any plan body,
the scope read back is whitespace-only exactly when the body was. That pins the
gate's discriminator to bytes examined, so it cannot quietly become "no signals
found", across unicode whitespace and CRLF.

`docs/INVENTORY.md` picks up the reference doc's new seal-time outcome table —
surfaced by the co-change gate, not by a lint failure.

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

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

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

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

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

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

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

* chore(#3908): backfill changeset pr number

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Measured on this tree, 2026-08-27:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

* chore(#3906): backfill changeset pr number

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Measured on this tree, 2026-08-26:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

I over-implemented, and that is reverted.

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

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

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

Five tests were pinning forms that never worked.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

frontmatter block independently, so the marker binds at the transform layer.

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

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

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

Refs #3881

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

ADR-3473 §8.1 review findings, addressed inline:

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

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

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

Root cause was two clobber sites, not one:

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

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

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

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

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

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

a3d5841117 fix(#3714): deliver an explicitly pinned model to the Codex worktree executor, and drop an unusable one (#3891)
* test(#3714): failing-first coverage for the dropped Codex worktree model override

Pins the argv contract for the orchestrator-worktree process dispatch: an explicit
model_overrides pin must reach the child as --model, while an unpinned, empty,
inherit, or profile-only configuration must emit no flag at all.

Five of the eight matrix rows are CONTROLS that pass before the fix. They carry the
weight here because this is an over-emission bug waiting to happen: resolve-model
returns 'sonnet' for the unpinned, empty and profile-only cases, so a fix that
threads its return value into argv would satisfy the positive row and emit
--model sonnet to Codex on every unpinned install -- the documented 400 that
ADR-2313 exists to prevent. The controls are what separate the correct fix from
the obvious one.

* fix(#3714): deliver an explicitly pinned model to the Codex worktree executor

resolveOrchestratorExec had no model input at all -- the descriptor carried only
command/args/cwdFlag/promptFlag -- so a resolved override had no way to reach the
spawned process even in principle. The baked gsd-executor.toml could not compensate
because this path spawns a process rather than dispatching a named agent.

Three parts, and the third is the load-bearing one.

The descriptor gains modelFlag (codex: --model), keeping the per-host knowledge as
descriptor data exactly as cwdFlag and promptFlag already are, so the scheduler
grows no per-host branch. No other runtime declares it.

The seam appends [modelFlag, model] and stays MECHANICAL: it does not know the
inherit sentinel, does not know which models Codex rejects, and reads no config.
Its sibling codex-agent-toml states that rule outright -- callers decide what to
strip. Argv order is baseArgs, model, cwd, prompt so the prompt remains the final
positional token. Omitting the model is byte-identical to before. A model starting
with '-' now fails closed as unsafe_leading_dash_model, the same hazard the prompt
and cwd guards already reject and which was silently accepted before.

The policy lives at the caller and passes ONLY an explicit, non-sentinel per-agent
pin. Passing null as the runtime resolver is what keeps profile and tier derived
models out of argv, which is what Codex's session-only model posture requires: the
model resolver returns 'sonnet' for the unpinned, empty and profile-only cases, and
emitting that revives the documented 400 from #2310/#2311 that ADR-2313 removed. So
the gate is the presence of an explicit pin, never that a value came back.

* fix(#3714): enforce the real-Codex value policy the sibling surface already applies

Review found one root cause behind a BLOCKER, two MAJORs, two MINORs and an
argv-injection finding: the dispatch path gated on the PRESENCE of an explicit pin
but never applied the VALUE policy that generateCodexAgentToml already applies to
the same config key. Textbook generative divergence -- and the parity row I wrote
tested resolver parity, not this policy, so it could never have caught it.

BLOCKER: a global ~/.gsd/defaults.json model_overrides.gsd-executor of 'sonnet',
'opus' or 'claude-sonnet-4-5' reached codex exec --model verbatim. That is the
documented 400 from #2310/#2311, arriving through the explicit-pin door rather
than the tier door. The issue asks for an explicit REAL-CODEX pin; real-Codex was
unenforced. Now dropped with a warning via the isAnthropicFlavoredModel predicate
#3241 single-sourced for exactly this reason.

Also: values are trimmed, so a whitespace-only pin is blank rather than
--model "   "; 'inherit' is matched case- and whitespace-insensitively, so
'Inherit' and ' inherit ' no longer reach the wire; and a value outside a model-id
charset is dropped with a warning. That last one closes the injection surface --
.planning/config.json travels with a clone, and values like
'gpt-5 -c approval_policy=never' or a command-substitution value previously reached argv verbatim,
where the spawner is an agent writing bash.

Every rejection DROPS AND WARNS rather than failing closed. An unusable exec is not
degraded, it is fatal: the dispatch step halts the wave after the worktree already
exists, so a config typo would have aborted execute-phase. The stale comment
claiming it degrades to sequential is corrected.

Separately, the seam's own empty-model handling contradicted the committed contract
and failed four tests on the remote runner. An absent, null or empty model is not an
error -- it means use the host default, the same degradation cwdFlag:null already
expresses. Unlike a prompt, where empty is a hang rather than a degraded run, so
that one stays fail-closed. Non-string values still fail closed.

Tests: the CLI rows were not HOME-hermetic and read the developer's real
~/.gsd/defaults.json, which is precisely the file the BLOCKER is about; HOME and
USERPROFILE are now sandboxed per call. Adds the global-pin regression, the
injection shapes, the case-variant inherit rows, and a real cross-surface
divergence guard.

* fix(#3714): close the flag-shaped pin, the case-variant alias, and the warning sink

Round two of review found three more defects, two of which both engines reached
independently, and all three were mine.

The charset allowlist put the dash INSIDE the character class, so a value made only
of allowed characters passed the pin policy silently and then tripped the seam's
leading-dash guard, producing exec:null. That is the wave-fatal path the whole
drop-and-warn design exists to avoid, reachable from a committed config file: -c,
--config, -p and --dangerously-skip-permissions all reproduced it. It also regressed
hosts with no model flag at all, where a dash pin turned a previously working
kimi-code dispatch into exec:null. The first character is now anchored, so a
flag-shaped value is dropped and warned like every other rejection, and the comment
that claimed this path was unreachable is corrected.

isAnthropicFlavoredModel folded case on its substring arm but not on its alias-set
arm, so SONNET, Sonnet, OPUS and HAIKU all reached Codex argv while lowercase sonnet
was correctly dropped -- the same 400 the drop exists to prevent. The predicate is
the one #3241 single-sourced so these surfaces cannot diverge, so folding case there
fixes the install-side .toml surface too.

The warning wrote the rejected value RAW to stderr. Every value that fails the
charset test contains by definition the characters the charset excludes, so it was a
guaranteed-reachable raw-to-terminal sink: an OSC sequence in a committed config
reached the operator's terminal byte for byte, and truncation could sever an escape
before its reset. The value is now sanitized before truncation.

Also from review: the allowlist rejected Vertex version pins like text-bison@002, a
false positive on a real model id; the policy ran host-neutrally so hosts with no
model flag printed a misleading drop warning on every dispatch; the invalid_model
branch had no test at all; and the changeset disclosed only that a pin is delivered,
not that an unusable one is now dropped with a warning.

* fix(#3714): single-source the model-id charset, bound the pin, keep the flag diagnosis

Round three found no blocking findings on either engine. These are the three
correctness items left in code I added.

The charset existed TWICE -- once to accept a pin, once to render a rejected one in
the warning -- and the two copies had already drifted inside a single commit: '@'
was added to the accept class and not the render class, so a Vertex-shaped value
rejected for some other reason rendered as text-bison?002. Both are now derived
from one definition, with a parity test asserting every character the matcher
accepts survives the sanitizer unchanged, so they cannot drift again.

A pin reached argv unbounded. CLAUDE.md documents the hazard: execFileSync aborts
on Windows above 32,767 characters of argv. A model id has no reason to be long, so
a pin over 200 characters is dropped and warned rather than truncated -- a truncated
model id is a different model id. Boundary rows at 199, 200 and 201.

The first character is now required to be alphanumeric, so '@evil' and '/c' no
longer reach argv. Security rates both inert on codex today, so this is hardening
rather than a live defect; it is here because it is one character of regex and
resolveOrchestratorExec documents itself as a general descriptor-to-argv seam that
other hosts may adopt.

Tightening the anchor made the leading-dash branch unreachable and, with it,
regressed the diagnosis: '-c' began reporting 'unsafe characters' instead of
'looks like a flag/option'. The dash check now runs before the charset test, which
both restores the actionable message for the most likely user typo and keeps the
branch live. A test pins the distinction between the three rejection messages so
the branch cannot silently die again.

* test(#3714): make the charset parity guard actually guard, and remove a false-green trap

Review proved by mutation that my parity test could not do what its own comment
claimed. It bound the expected character set to a local that was assigned and
discarded, and the shared definition was not exported, so widening that definition
left the test green. A comment overstating what a test guards is worse than no
comment, because the next reader trusts it. The shared body is now exported and
asserted equal, and I watched the assertion fail against a widened definition
before keeping it.

The sanitizer regex was module-scope, carried the g flag and was exported.
Production only uses it with replace, which resets lastIndex, so there was no live
bug -- but test() on a g-flagged regex alternates between calls, so any future test
reaching for it would false-green. The g-flagged copy is now internal to the one
call site that needs it and the exported companion carries no flags, which removes
the footgun rather than documenting it.

Also notes at the shared definition that it is interpolated into both a positive and
a negated character class, so only plain characters and ranges are safe to add.

No runtime behavior changes: the accept set, the anchor, the length cap, the
sanitizer output, the rejection ordering and all three message texts are
byte-identical, re-verified through the real CLI.

* chore(#3714): backfill changeset pr number

* chore(#3714): re-trigger CI after the GitHub Actions outage

The workflow runs for this branch were created during the Actions major outage on
2026-08-26 and never got scheduled. They are wedged: GitHub reports them queued,
refuses to cancel them, and refuses to rerun them because it believes the workflow
is already running. The Tests run is also pinned to a superseded sha, so no test run
exists for the current head at all.

Actions is operational again and the repo-wide queue has drained, so a fresh push is
what creates schedulable runs. This commit is empty on purpose: nothing about the
change is being altered, and the verified content is byte-identical to 7860c6ccc.

832dcbb751 fix(#3707): surface UAT rows audit-uat silently dropped, and never report a clean result for a file it could not read (#3887)
* test(#3707): failing-first coverage for the three parseUatItems false negatives

Nine tests that must be red and three controls that must already be green.

The controls are the point of the split. `result: pass` staying unsurfaced is
what stops the fix inverting the filter so eagerly that every passing test
becomes an outstanding item, and the classic single-line shape is the no-churn
control for rewriting the adjacency regex. Both were confirmed green against
the current build before being written down; a control that is red today would
be a second bug, not a control.

Each failing fixture was run through the built parser first and returns []
for its stated cause — the issue row matched then filtered, the block-scalar
and wrapped rows never matched at all, the all-unparseable file vanishing whole.
That evidence is in 50-test-matrix.md rather than asserted.

Tests target ../gsd-core/bin/lib/uat.cjs, the built live module, and drive the
real CLI through runGsdTools. #3706 lost a full RED/GREEN cycle to tests that
imported a different copy of the function under test, so the import target was
verified before anything was written.

* fix(#3707): stop parseUatItems dropping outstanding UAT rows

Three independent false negatives, all in the audit path, plus one the issue
did not mention.

The matcher no longer requires `expected:` and `result:` to be adjacent single
lines. It slices each `### N.` block to the next heading and reads the first
`result:` line within it, taking `expected:` from parseExpectedFromTestBlock —
the seam that already parsed both the block-scalar and inline forms correctly
and was sitting unused two hundred lines away. Two parsers in one module read
the same field with different grammars; now there is one.

The result filter is inverted from an inclusion list of three to an exclusion
of a minimal PASS set. This was the issue's one open design question, which the
reporter explicitly declined to answer for the maintainer; it was asked and
decided deliberately. The fail-safe direction is what parseGapsItems documents
seventy lines below for this same false-negative class (#2286): a token nobody
recognised surfaces rather than vanishing. The trade is a visible, correctable
false positive if a project invents a novel pass-word, against today's silent
and invisible drop.

`issue` also needed a category. It is template-sanctioned with its own `issues:`
counter, but categorizeItem fell through to `unknown` — surfacing it in the
wrong bucket would have been a half-fix.

Finally, a file parsing to zero items no longer vanishes with its frontmatter
`status:`. One with a non-terminal status is reported with `parse_gap: true`,
so the reader gets a cue to look; a `complete` one stays omitted as before.
That is what made the first two defects dangerous rather than merely lossy —
the audit omitted the phase instead of under-counting it.

* fix(#3707): close the review blockers, including a regression I introduced

The remote suite was RED on the previous commit and both reviews found real
defects. Everything below was verified by execution, not by reading.

I introduced a regression against origin/next. The rewritten result matcher was
END-anchored where the old one was not, so `result: pending (blocked on
staging)`, `result: [skipped] # no device` and `result: blocked - waiting` all
returned a row before this branch and returned nothing on it — me reproducing
the exact defect class this issue exists to kill, in the fix for it. The anchor
is gone and each shape has a regression test; trailing text now falls back to
`reason` when the block has none.

`parse_gap` was inferred from the wrong signal. It fired for ANY zero-item file
whose status was not `complete`, which asserted something false about a
perfectly-parsed all-pass file, swept in archived phases left at `testing`, and
is what turned the #2286 Gaps tests red — a control this change was supposed to
keep green. It now derives from headings SEEN BUT UNYIELDED, reported by a new
parseUatItemsWithStats, so an all-pass file and a Gaps-only file are not parse
gaps and a file whose blocks carry no `result:` line is.

The fix was also invisible end to end, which both reviewers caught
independently. parse_gap entries carry no items, and both audit-uat.md and
progress.md gate on `total_items === 0` — so the headline symptom, the phase
vanishing, still reproduced for a user and only the raw JSON had changed. There
is now a `parse_gap_files` counter and both workflows gate and report on it.

Also: categorizeItem compared case-sensitively while the new PASS check
lowercased, so `result: PENDING` surfaced as `unknown`; blocks are bounded at
the next heading of any level, so a trailing `## Gaps` entry no longer bleeds
its `reason` onto the preceding test; dead unreachable fallbacks removed; and
the all-pass control was strengthened, since asserting only `total_items === 0`
let it stay green through the bogus parse_gap entry.

* chore(#3707): acknowledge the workflow growth the fix required

The emitted-attribution guard went red because audit-uat.md and progress.md
grew, and it is right to ask: runtime-loaded workflow prose is the product,
so growth there is a real change to what an executing agent reads.

The growth is not incidental to this fix, it IS the fix reaching a user. Both
reviewers found independently that emitting `parse_gap` in the JSON changed
nothing observable, because both workflows gated their output on
`total_items === 0` and parse-gap entries carry no items — so a phase whose
rows could not be parsed still printed "All Clear" and still vanished from the
progress report. The widened gates and the branches that name the unparsed
files with their phase and path are what close that.

Acks exactly the two paths the guard reported, keyed on the bare filename. The
three spent acknowledgments it also listed are inert by its own description —
the base already absorbs them — so they are left alone rather than swept up
here, where they would just add unrelated churn to this diff.

* fix(#3707): close the mixed-file blocker and the second false-clean surface

The suite was GREEN and the isolated review still found a blocker, which is
the useful part: none of this was covered by a test.

A MIXED file dropped its unparseable rows silently. `parse_gap` sat behind an
`else if` on `items.length > 0`, so one parseable row was enough to discard
`headingsSeen` entirely — a file with one pending row and two unreadable blocks
reported one item and no gap. That is the exact class this issue exists to kill,
reappearing inside its own fix for the third time. The flag is now set
independently of item count and the entry carries `unparsed_blocks`, so the
count is quantified rather than merely flagged.

A `result:` inside a fenced code block was being read as real, so a PASSING
test could be reported as outstanding from a value in a code sample — another
regression against origin/next, whose adjacency regex ignored it. Field scans
now run against a fence-stripped copy while `expected:` still reads the raw
block, since a block scalar may legitimately contain fenced-looking text.

The workflow report was still unreachable whenever anything else was
outstanding: the unparsed table lived in the all-clear branch, so a project with
one pending row in phase 01 and an unreadable phase 02 rendered phase 02
nowhere. It now fires on `parse_gap_files > 0` from the `present` step.

planning-inspect was the second surface making a false-clean claim — for
exactly the files audit-uat now flags it emitted `scope: 'complete'` with an
empty unresolved list, positively asserting completeness over a file it could
not read. It consumes the stats now and reports SCOPE.TRUNCATED with a
`uat_unreadable` diagnostic, reusing the vocabulary already used two lines above
for an unreadable file rather than inventing a token.

Also: headings with no name no longer vanish whole; the trailing-text-to-reason
synthesis I had added is removed, since it was never required by the blocker and
silently changed categorization for `result: [skipped] # no device`; the emitted
`result` token is normalized to lower case so it agrees with `category` in a
published contract; and an O(n^2) indexOf is gone from the heading loop.

* fix(#3707): stop rows stealing each other's fields, on all three surfaces

The suite was green when the security review found these. Two are
blocker-severity and one of them is a direct hit on my own verification.

A `### N.` line indented two spaces inside an `expected: |` scalar is a valid
ATX heading, so it became a phantom row that STOLE the real row's result token
while the real row vanished. I had probed this shape and declared it fixed — my
probe asserted the item COUNT and the result token, both of which the phantom
satisfied, so it passed for exactly the reason it should have failed. Block
scalar bodies are now masked to blank lines (line count preserved, so offsets
still line up) before headings are tokenized, and the tests assert row IDENTITY
— number and name — not presence.

Feeding parseExpectedFromTestBlock the raw slice let one row publish another
row's `expected:` from inside a fence the stripped view had correctly excluded.
Blocks handed to it are now clipped at the first fence opener. This was not
cosmetic on the render-checkpoint path: a checkpoint banner a HUMAN reads and
answers was rendering a different row's expected text.

A balanced fence pair straddling a test block made that heading invisible, so
an outstanding row disappeared with no item, no gap and no count — the exact
false-clean this issue exists to close, and a regression against origin/next.
Suppressed `### N.` lines now count toward headingsSeen so the file is flagged.

An unterminated fence swallowed the rest of the document including `## Gaps`,
producing a whole-file false clean. Such a file is now treated as a parse gap,
following what uat-predicate already does.

Found and fixed inline while there: parseExpectedFromTestBlock's scalar opener
required a bare newline, so a CRLF `expected: |` fell through to the inline arm
and published `expected: "|"`, silently discarding the entire value. The same
fall-through hit `|-` and `|+`.

parseFirstPendingTest had the identical exposure on the render-checkpoint path
and now shares the same masking and clipping. Five legitimate fixtures — inline
expected, a real block scalar, CRLF, bracketed pending, and a first-pending
that is not the first test — are byte-identical before and after.

Also from the code review: the admit condition disagreed with the terminal
status guard, so a `status: complete` file with an unparseable block was
emitted as an empty entry that rendered nowhere but inflated total_files; a
control test was vacuous because its fixture filename did not match its phase
dir, so #3511 scoping meant the file was never opened — and that vacuity is why
the admit regression shipped green; an unterminated fence discarded the flag
that would have caught it; `### 1.2.3` parsed as test 1; and planning-inspect
did not share the terminal-status rule.

* test(#3707): assert what the render-checkpoint fix actually does

The suite went red on three of my own tests and the source was right — the
assertions were wrong, in a way worth naming.

One forbade the rendered checkpoint from containing `### 3. Fake Row`. But in
that fixture the string IS row 1's legitimate `expected:` block-scalar value; a
heading-shaped line inside a scalar is inert text and rendering it is correct.
The test was forbidding correct output. It now asserts row IDENTITY — the
checkpoint is for test 1 named Alpha and never test 3 named Fake Row — which is
the property that actually distinguishes the fix from the bug.

The other expected success where the correct outcome is a clean error: row 1 in
that fixture has no `expected:` of its own and only ever appeared to have one by
stealing row 2's from inside a fence. Depending on the bug to produce a pass is
how a test ends up pinning the defect. The fixture now gives row 1 its own
value and asserts the checkpoint carries it and never the fence-hidden text, and
the error path gets its own test asserting it fails cleanly without leaking.

All three were checked against the real rendered output before the assertion was
written, and each was reasoned through for whether it can fail: the identity
test breaks if a phantom row is parsed, the clipping test breaks if the raw
block is read again, and the error test would pass-not-fail under the old
stealing behavior.

* fix(#3707): correct the scalar masking frame and cover every YAML block opener

Two reviews independently found the same blocker, and it is the sharpest defect
on this issue: maskBlockScalarBodies computed line offsets in UTF-16 units but
spliced them into Array.from(content), a CODE POINT array. One emoji anywhere
earlier in the file shifted every later mask write, so the mask blanked the
wrong characters and spilled past line ends. Measured: at two astral characters
a result token truncated `pending` to `pendi` and recategorized to unknown; at
six the real row vanished; at twelve the FOLLOWING row's `result: blocked`
disappeared and the file reported clean. That is the false-clean class this
issue exists to close, reintroduced by the mitigation written to prevent it, and
defeating both new detectors at once. The mask is rebuilt line by line now,
which is frame-agnostic and length-preserving by construction.

The opener grammar was also incomplete. YAML block scalar headers take an
optional indentation indicator and an optional chomping indicator in either
order, so `|2`, `|2-`, `|-2`, `>2`, `>2+` are all valid — and none were matched.
An unmasked `expected: |2` body meant a `### N.` line inside the value became a
real heading: reproduced, row 1 disappeared and a fabricated row 2 named
"Phantom" took its identity.

Fixing that exposed a third instance of the same family, found by my own probe
rather than by review: the value extractor understood only the `|` openers, so
every `>` folded scalar published the LITERAL OPENER as its value — `expected`
came back as ">" or ">2+" and the whole scalar was discarded. The extractor now
shares the opener grammar and implements real folding, joining paragraph lines
with a space and turning a blank line into a newline, rather than pretending `>`
means `|`.

Also from the reviews: the shortfall counter scanned the masked copy but not a
fence-stripped one, so a `### N.`-shaped line inside a properly closed
documentation fence — the ordinary way to document the row format inside a UAT
file — counted as a suppressed row and flagged the file against nothing; and
clipping at the first fence discarded a legitimate `expected:` that appeared
after a closed fence, which is silent field loss.

Every opener now verified for both row identity and exact extracted value, in
LF and CRLF, alongside the emoji fixtures at 1/2/6/12.

* refactor(#3707): replace the scalar masking with a column-0 heading rule

The fix had grown to five helpers whose only job was undoing one
over-permissive rule: tokenizeHeadings treats a heading indented up to three
spaces as real, so a `### N.` inside an `expected: |` body was parsed as a row
and stole the real row's identity. Every blocker in the last three review
rounds came out of that machinery rather than the reported bug — worst of all
a UTF-16-versus-code-point frame mismatch that corrupted any document
containing an emoji.

A UAT test heading is at column 0. The shipped template puts all of them there,
no `*UAT*.md` in the repo has an indented one, and the only indented `### N.`
lines in the tree are the adversarial fixtures that must not parse. Requiring
column 0 makes a scalar-interior heading a non-heading by construction, so
maskBlockScalarBodies, indentWidthOf and BLOCK_SCALAR_OPENER_RE are gone along
with the mask-invariant test that existed only to guard them. The frame bug is
now structurally unreachable: no code-point array or offset splicing remains.

The premise was incomplete and the reviewer caught it rather than forcing it
through. Masking had been doing double duty — it also hid indented FENCE
delimiters from the tokenizer, so removing it let a two-space fence inside a
scalar body swallow a later column-0 row. The alternative on offer was to
rewrite that test to assert the row is merely counted, which is a behavior
regression dressed as a passing suite. Instead there is a small line-based pass
that blanks only indented fence delimiters — same "column 0 is structure" rule
extended consistently, no YAML knowledge, and line-based by construction so the
frame bug cannot come back. It was proven load-bearing by a negative control:
reverting the wiring reproduces the regression exactly.

Kept, because they fix defects column-0 does not touch: the fence clipping that
stops one row reading another's `expected:` from inside a fence, and the folded
scalar handling that stopped `expected: >` publishing the literal ">".

Also corrects a comment left pointing at a symbol this commit deletes.

* fix(#3707): blank neutralized fence bodies, and give both parse paths one grammar

Reviewing the simplification found two more, and the first is row theft again —
the sixth time this class has surfaced on this issue, and the second time
inside a mitigation written to stop it.

Neutralizing an indented fence blanked only its DELIMITER lines. If the block's
body held a column-0 `### N.`, un-hiding the delimiters made that line a real
heading, which then took the preceding row's fields: an `### 1. Alpha` document
came back as a single row 9 named Phantom, with Alpha gone. Neutralized blocks
are now blanked open-to-close, body included, which is the honest reading of
the intent — an indented fence inside a scalar is content, so nothing in it
should be able to produce structure. The raw block is still what the expected
extractor reads, so a legitimate `expected: |` carrying a fenced code sample
keeps its full text.

The two parse paths also disagreed about what a test row IS.
parseFirstPendingTest filtered on `^\d+\.\s+` while parseUatItemsWithStats used
`^\d+\.(?!\d)`, so `### 3.Foo` was a row when audited and not a row when
resumed. Both now share one predicate and one extractor. The extractor mattered
as much as the filter: the checkpoint path's name-mandatory pattern would have
skipped exactly the shapes the widened filter admits, so fixing the filter alone
would have moved the divergence down a line rather than closing it.

Also from the security pass: parseUatItems had become an export with no callers
and no direct test once both consumers moved to the stats form. It stays, since
deleting an exported symbol from a shipped module is a contract change and not
this issue's business, but it is now documented as the items-only wrapper and
has a test. And the PASS check lowercased a value that extraction had already
lowercased; normalization now happens once.

* fix(#3707): revert the whole-block fence blanking, and pin the rule instead

My previous commit over-corrected and the suite caught it. Blanking a
neutralized fence block open-to-close destroys content legitimately living
between the delimiters, and on an UNTERMINATED opener it blanks to EOF and
deletes every later row. No framing makes that correct, and it is what turned
two earlier tests red.

The "blocker" that prompted it was my own misreading. This change adopted the
rule that column 0 is structure and indentation is content. Under that rule an
indented fence delimiter is not a fence, so a column-0 `### 9.` sitting between
two indented delimiters genuinely IS a heading, and a `result:` after it
genuinely belongs to it. That document is malformed and the parser reading it
that way is consistent, not stealing. Nothing is silently lost either: the row
whose result was taken surfaces as the parse gap.

So the blanking is back to delimiters only, and rather than leaving the
question open, the behavior is now pinned by a test asserting the rows by
identity, with the rule stated at the site — so the next person does not
oscillate the way I just did.

Kept from the reverted commit: the shared row-heading grammar and extractor
across both parse paths, the parseUatItems wrapper documentation and its test,
and the single point of lowercasing.

* fix(#3707): scope the shortfall scan, and stop neutralized content becoming structure

The security review found a HIGH that is the earlier frame-mismatch bug wearing
different clothes. The shortfall scan compared a SECTION-scoped raw line count —
the `## Tests` body — against a DOCUMENT-wide token count. So a single legal
`### N.` row anywhere outside `## Tests` decremented the shortfall and switched
the fence-straddle detector off: an identical `## Tests` section went from
`headingsSeen 1, parse_gap true` to `headingsSeen 0, no gap` purely because a
`## Prior` section existed. A document whose rows render as ordinary blocked rows
in any CommonMark renderer audited as totally clean. Both sides of the
comparison now come from the same surface, by filtering tokens to the scan
span rather than re-tokenizing, so there is no second offset basis to keep in
step.

Neutralizing a fence could also promote its former CONTENT into structure: a
column-0 delimiter run inside an indented pair became an opener once the
enclosing delimiters were blanked, hiding every later heading to EOF. Column-0
delimiter-shaped lines inside a neutralized block are now blanked too — and only
those, so a column-0 heading between neutralized delimiters is still a heading
(the pinned behaviour) and the field lines of a row living between two scalars
still survive. The reviewer corrected my repro while fixing it: an even number of
inner runs re-pairs and hides nothing, so the live shape needs an odd one, and
both are now tests.

Two more from that pass. A legal scalar header carrying a trailing comment
(`expected: | # sample`) failed the end-anchored grammar, publishing the literal
header and raising a false gap. And the indented-row counter walked backwards
per row: 3.6 seconds at sixteen thousand rows, now 15ms, via one forward pass —
though the reviewer also established my example was not the quadratic shape,
which needs an uninterrupted scalar body.

Carried in from the previous round: the indented-row counter keys on any block
scalar rather than only `expected:`, so a template-sanctioned `reported: |`
holding user prose with a heading-shaped line no longer raises a false gap; and
`reason:`/`blocked_by:` read block scalars through the same shared extractor
instead of publishing the literal `"|"`, which also means a multi-line reason
can finally reach categorizeItem — a `reason:` mentioning a server now
categorizes as server_blocked, which was impossible while the value was thrown
away.

* fix(#3707): make the shortfall scan whole-document on both sides

Second HIGH in this area, and the diagnosis is the useful part: I closed the
first one by making the two sides agree, but I did it by NARROWING the token
side to the `## Tests` span while the parse side stayed whole-document. Rows
outside that section are still parsed and surfaced when visible, so when a fence
straddled one it fell through both sides of the comparison — no item, no gap,
file never entered the results at all. A `## Regression Tests` section, or a
second `## Tests` (collectSection takes the first), audited as totally clean
while origin/next surfaced those rows.

Both sides are whole-document now. Symmetry is the property that matters here;
every attempt to be clever about which scope to compare has produced one of
these, twice at HIGH severity.

That reinstates a known over-report, deliberately: a `### N.`-shaped line inside
a closed fence in a `## Notes` section — the ordinary way to document the row
format — counts as a suppressed row and raises a gap on a file with nothing
missing. Noisy, but visible and fail-safe, against two silent false-cleans on
the other side of the trade. This issue exists to eliminate false cleans, so the
trade goes that way, and the reasoning is written at the site so it does not get
optimized back.

Three existing tests encoded the retired scoping and are replaced rather than
worked around: two now assert the accepted over-report, and one asserting a
4-space row is "not counted" was already contradicted by widening the counter to
any indentation — refusing to PARSE a 4-space heading is right, refusing to
COUNT it reopened the hole the counter exists to close.

Also in this commit, from the same review round: the inner-delimiter sweep tested
a column-0-anchored pattern, so an INDENTED delimiter inside a neutralized block
was still promoted to structure and lost a row; it is indent-tolerant now.

A refinement was identified and deliberately not taken — keying the
documentation-sample exemption on the fence info string rather than on section
scope. It is content-based and symmetric, so it would not reintroduce the
asymmetry, but it belongs in its own change rather than riding this one.

* docs(#3707): correct two claims in the over-report justification

Both from review, both comment-only, and both matter because they would
mislead the next person into "fixing" something correct.

The over-report note called the triggering shape "the ordinary way to document
the row format". It is narrower than that: the scan requires literal digits, so
the conventional placeholder `### N. Name` does not trigger it at all — only a
sample written with real numbers does, and no phase UAT file in-tree has one,
only the shipped template, which selectPhaseUatFiles never scans. A maintainer
who tested the documented placeholder form would find no over-report and could
reasonably conclude the pin was stale. That is now stated, and it also makes the
trade look better than I claimed: the real-world frequency is lower.

The attribution guard is described as structural rather than positional. It is
positional in one respect: the walk stops at the nearest column-0 line, so a
block scalar nested inside a `## Gaps` bullet is transparent to it and a
heading-shaped line in that value gets counted. Same accepted over-report,
reached by a path the comment did not mention — recorded so it is not later
mistaken for a new defect.

* fix(#3707): a complete status no longer switches off the parse-gap detector

The security review named this as the last silent-clean path in the change, and
its phrase is the right one: a self-declared kill switch over the very detector
this issue built. A file whose frontmatter said `status: complete` was omitted
unconditionally, so one containing a fence-straddled `result: blocked` computed
headingsSeen = 1 — the detector fired — and then emitted no entry at all. The
audit reported nothing.

The predicate is now status-independent: a file is surfaced when blocks were
seen but yielded nothing, whatever it claims about itself. A terminal status is
an assertion by the author, and an assertion is exactly what must not be allowed
to suppress the signal that would contradict it. What does not change is the
thing the status is actually for — a complete file with nothing to parse, and a
complete file whose rows all parse and all pass, both stay silent, verified
through the real CLI.

I replaced a control test of mine, and it is worth saying why that is not a
weakening: its name was already false. "A zero-item file with a complete status
is still omitted" used a fixture with a `### 1.` block carrying no `result:`
line, so headingsSeen was 1 — it was never a zero-item file, it was the kill
switch itself, pinned. The intent it claimed is now covered by two stricter
tests, one for a file with no blocks and one for a file where every row parses
and passes, each asserting both that no entry exists and that no items are
counted, where the old test asserted only the former.

Everything else is byte-identical: 61 regression cases and the non-complete
equivalents of all four shapes produce exactly the same output as before, with
the delta confined to the two cells this change is meant to move.

* fix(#3707): close the moved kill switch, and keep the archive out of the live gate

Both reviewers independently found that closing the kill switch on one surface
left it standing on the other. cmdAuditUat dropped the terminal-status guard,
but buildUatRows in planning-inspect kept it — and its comment justified that by
claiming to mirror a guard cmdAuditUat no longer had. One byte-identical file
with `status: complete` and a fence-straddled `result: blocked` reported
parse_gap through audit-uat while planning-inspect published
`uat.scope: "complete"` with no diagnostic at all. That is the repo's own
generative-fix-divergence class, and no test pinned that arm, which is why it
survived. The clause and the false comment are gone and the arm now has tests.

Removing it exposed a MAJOR the security pass had not reached: archived phase
dirs are deliberately not milestone-filtered and archived UAT files are
`complete` by definition, so status-independence newly admitted the entire
project archive. One live pending row plus four signed-off milestones produced
parse_gap_files 4 — and since progress.md gates Verification Debt on that
counter, a mature project would have warned on every run, forever, about closed
history no user action can clear. Warning fatigue that buries the next real gap
is the feature defeating itself.

So the counter is split rather than suppressed: `parse_gap_files` counts live
phases only and remains the gate, `archived_parse_gap_files` carries the rest,
and every archived entry stays in `results` with its parse_gap and its
milestone. Nothing became silent; the live signal stayed actionable. Both
workflows report the archived bucket as closed history rather than as something
to act on.

The scope cascade is also decoupled, on the security reviewer's advice that it
is load-bearing here rather than a follow-up: `uat.scope` still reports
TRUNCATED honestly so no completeness is claimed over an unread row, while the
accepted fence-shortfall over-report no longer flips the aggregate fold that
withholds a phase's percentage. A genuinely unreadable file degrades as before.

Also corrects a frequency claim of mine: "no phase UAT file in-tree triggers
this" was true over a sample of zero, since the only UAT file in the tree is the
shipped template. The comment now says the shape is uncommon, which is what I
can actually support.

* fix(#3707): state that the live/archived split does not extend to outstanding_debt

Review MINOR: the split's rationale read as though it governed every counter, but
`summary.total_items` was never split — so a single archived `result: pending` row
re-trips the same Verification Debt warning the split exists to stop. The asymmetry
is deliberate: an archived parse gap is a row nobody can read, so the warning can
never be cleared, whereas an archived pending row is legible work someone can still
pay down by retesting. Debt that can be settled stays counted. The prose now says so
at the point of the claim, instead of leaving the next reader to file it as a miss.

Also rewrites the changeset, which described only the secondary fixes and omitted all
three defects the issue actually reports: `result: issue` dropped, any wrapped or
block-scalar `expected:` never matched at all, and the phase vanishing outright.

* fix(#3707): count every parse gap, dropping the live/archived split

The split had two regressions, both reproduced through the real CLI, and its
premise was false.

uat.cts carries #2766's rationale ~190 lines above the code I added: 'Outstanding
UAT items do not stop mattering when a milestone closes: a deferred human-UAT
scenario or a skipped live-stack test is exactly what gets archived still-open.'
So 'archived UAT files are complete by definition' was never true, and the split
rested on it.

Regression 1: archived-ness was inferred from path shape alone. A phase in the
CURRENT milestone, status in_progress, filed under .planning/milestones/v1.1-phases/
was classified archived and demoted out of the gate — live work reported as closed
history that needs no action.

Regression 2: the split was one-sided. total_items has no archived split, so an
archived outstanding row that PARSES gates Verification Debt while the identical
row that fails to parse was informational. The parse failure was what buried the
debt — the exact bug class this issue exists to fix, re-created one surface over.

parse_gap_files counts every parse_gap entry again, archived or not, so it agrees
with total_items on what archived means. The pre-existing archived_milestone field
and archived-phase scanning are untouched. Regression tests added for both cases.

* fix(#3707): correct the changeset clause left behind by the split revert

The changeset was rewritten before the split was removed, so its final clause
still claimed archived parse gaps are counted separately because signed-off
history is not work anyone can act on. There is one counter now, and that premise
is the one uat.cts refutes and the revert was made over. This text lands in
CHANGELOG.md verbatim, so it would have shipped a description of behavior the
code does not have.

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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

Refs #3873

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

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

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

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

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).

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.

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.

- 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.

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

* 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

* 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.

8442d984b9 fix(#3809): route runtime-loaded markdown through the gsd_run launcher (#3815)
* test(#3809): generalize dead-ref guard into a rule table (failing first)

The #2020 guard hardcoded `sdk/(src|dist|handlers)/` — the three dead paths
that had caused that storm. That proved those three paths were gone and said
nothing about the class, so #3809 reproduced the identical Windows find.exe
storm under a different token and the guard could not see it.

Replaces the single regex with a rule table over the same runtime-loaded
markdown surface, adds `commands/` to the scan set (previously uncovered),
and adds rule B: the runtime shim filename must never appear in command
position, because it is not a PATH command and an agent that meets it falls
back to locating the file.

Rule B's matcher is deliberately lenient — the launcher's own resolver
assignment, `node <path>/<shim>` calls, bare paths, and prose that names the
file all stay unflagged, each pinned by a negative-space row.

This commit is expected to FAIL: 50 offenders across 23 files remain in the
tree. The remediation lands next.

Refs #3809

* fix(#3809): route every workflow call through the gsd_run launcher

50 places across 23 runtime-loaded workflow, agent, reference, and command
files instructed the agent to run the runtime shim by filename. That filename
is not on PATH under any name -- package.json ships gsd-core, gsd-tools,
gsd_run and gsd-mcp-server -- so the call exited 127, the file-shaped token
sent the agent looking for the file, and on Git Bash for Windows the resulting
`find /` walked the entire drive (7268 CPU-seconds in the report) until
somebody killed it by hand.

CONTEXT.md -> Runtime Launcher Module already makes gsd_run the single entry
point: "Canonical space-safe shell preamble (`gsd_run`) used by every workflow
bash block to invoke the GSD runtime CLI." These sites predate that rule --
they trace to 0e6907050 (docs(#195): migrate workflow markdown off gsd-sdk
query), which swapped one non-PATH token for another.

Two further instances of the same class surfaced during remediation and are
fixed here rather than left for later:

  - references/model-profiles.md prescribed `node <shim> effort sync` with no
    path at all; node resolves a bare filename against cwd, so it fails the
    same way.
  - references/universal-anti-patterns.md rule 25 instructed every agent to
    "use <shim>" when shelling out. That rule did not contain the defect, it
    prescribed it repo-wide.

Five "(or legacy <shim>)" parentheticals left dangling by the substitution are
removed; after the rewrite they offered the non-resolving form as an
alternative.

The guard from the previous commit now passes. Its node-prefix exemption was
tightened to require a path separator, which is what exposed model-profiles.

Fixes #3809

* fix(#3809): key the guard on the CLI's whole verb roster, not observed usage

Review found the first cut of rule B repeating the very mistake it exists to
prevent. Its verb set held query, commit and effort -- the verbs that happened
to appear in the tree -- so it could not see `<shim> phase add`,
`<shim> state load`, `<shim> verify ...` or twenty-odd other real single-word
subcommands. A guard that only recognises yesterday's offenders is not a guard.

The set is now the CLI's full advertised roster, unioned from the usage banner
and HOST_COMMAND_ROUTERS (which carries verification, planning, uat, stats,
todo and windows, all absent from the banner).

Widening it immediately caught a live offender the first pass had missed:
references/planning-config.md prescribed `node <shim> worktree set-baseref`
with no path. Fixed here.

Also drops the "a hyphen or a dot means subcommand" heuristic, which was
unsound for prose -- it flagged `built-in` and `v1.2`. Detection now keys
entirely on the roster, testing the first dot-segment so that phase.add and
state.patch still match while prose does not. Both false positives are pinned
as negative-space rows.

Guard verified against the pre-fix tree at origin/next: 52 offenders across 25
files, and 0 after this branch's remediation.

* fix(#3809): derive the verb roster from the router; repair launcher parity

Standards review caught the guard repeating the defect it exists to prevent.
Its verb list was a hand-copied literal -- and worse, transcribed from an
INSTALLED older binary, so it was missing 22 verbs this tree actually ships
(websearch, windows, state-snapshot, context-predicates and the dispatch-*
family among them). gsd-tools.cjs already carries three hand-maintained
rosters whose drift is a named defect pinned by the parity test in
tests/commands.test.cjs; a hand-copied fourth was that same defect wearing a
guard's clothes.

The roster is now derived from HOST_COMMAND_ROUTERS + TOP_LEVEL_USAGE, lazily
and memoised, with `query` supplemented explicitly -- it dispatches through
the routing hub ahead of the host-router table, so it appears in neither
export, yet 45 of the 50 offenders used it. A parity test pins the derivation.

Two regressions this branch introduced, both caught by the remote runner:

  - runtime-launcher-parity: rewriting a comment in gsd-research-synthesizer.md
    put a `gsd_run` token at line 65 while the canonical preamble sits at 158,
    breaking "exactly ONE preamble, before the first gsd_run call". The comment
    is descriptive and needs no command token at all; it now names none.
  - The #2751 guard's PROSE_ALLOWLIST entry for that same line went stale once
    the line stopped carrying a bare mention. Pruned, exactly as that guard's
    own stale-entry test instructs.

Also corrects git-planning-commit.md, where the first pass rewrote only the
trailing "legacy" clause and left the sentence reading backwards.

Note the #2751 guard and this one are complementary, not duplicates: its regex
requires whitespace immediately after `gsd-tools`, so it cannot match the
`.cjs` form, and this one only matches the `.cjs` form.

Refs #3809

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

* fix(#2751): extend the bare-command guard to references/ and commands/

The #2751 guard has only ever scanned agents/ and gsd-core/workflows/. Two
runtime-loaded directories were never in its scan set, and 47 bare
`gsd-tools <verb>` calls had accumulated there unseen -- the same defect that
guard exists to catch, in the rooms it never entered.

  - gsd-core/references/: 37 calls, all rewritten to gsd_run. references are
    fragments inlined into a parent that defines the launcher, which is why 21
    of the 22 files already using gsd_run carry no local preamble.
  - commands/gsd/: 10 operative calls rewritten. The remaining 10 are
    descriptive prose ("resolved inside the workflow via ...") and are
    allowlisted with reasons, bringing PROSE_ALLOWLIST to 15.

commands/ also came under launcher propagation. sync-runtime-launcher.cjs
walked only WORKFLOWS_DIR and AGENTS_DIR, so every preamble under commands/
was a hand-pasted copy nothing propagated and no test checked -- graphify.md
had accumulated five. It now walks COMMANDS_DIR too, which collapses those
five to the canonical one-per-file, and runtime-launcher-parity gains a
(B-commands) arm mirroring (B-agents) exactly so the placement stays honest.

The parity arm keys on shell blocks, so commands/gsd/workstreams.md and
config.md -- which name gsd_run only in inline backtick prose -- are exempt,
as they should be. gsd_run is itself a shipped npm bin, so those inline
instructions resolve from PATH exactly as the gsd-tools form they replace did.

skills/ is deliberately NOT added to either guard's scan set: it is generated
from commands/ and pinned by lint:generated-sync, so guarding the source
guards both, and scanning the mirror would double-report every future
offender. Regenerated here.

* test(#3809): acknowledge the one emitted file this change grows

The emitted-attribution gate failed on the previous sha: gsd-research-synthesizer.md
grew 3 bytes (13847 -> 13850) with no acknowledgment. The substitution SHRANK the
other 19 emitted files, which is why the growth arm was not expected to fire at all.

The 3 bytes are unavoidable. Line 65 is a descriptive comment inside a fenced block;
naming any command there puts a gsd_run token ahead of the file's canonical preamble
at line 158, which runtime-launcher-parity's (B-agents) arm correctly rejects. So the
comment names no command and says where the config is actually loaded instead, which
reads longer than the token it replaced.

Acks only the path the gate reported, per the fragment rules.

* revert(#2751): drop the commands/ half — three contracts pin it in place

The remote runner refuted the commands/ extension outright. Reverting it and
keeping the references/ conversion, which passed.

What broke, all of it caused by bringing commands/ under launcher propagation:

  - graphify.md's five per-block preambles are LOAD-BEARING, not accumulated
    drift. tests/graphify-visualization.test.cjs extracts individual Step-3
    shell chains and executes them standalone, so each fenced block needs its
    own definition of gsd_run. Collapsing them to the canonical one-per-file
    produced `bash: gsd_run: command not found`, exit 127, across four tests.
    The "define once per file" contract holds for workflows and agents because
    nothing extracts their blocks in isolation; commands/ is not like that.
  - explore.md broke "the preamble that DEFINES gsd_run must appear before the
    first USE of gsd_run anywhere in the file".
  - tests/gsd-tools-path-refs.test.cjs (#1766) ASSERTS that
    commands/gsd/workstreams.md contains the literal string
    `gsd-tools query workstream.list`. Rewriting it to gsd_run contradicts a
    test that pins the opposite, so the two guards disagree about that file by
    construction.

So commands/ is not a scan-set widening. It needs those contracts reconciled
first, and that is its own change. SCAN_DIRS keeps gsd-core/references/ and
drops commands/, the ten commands/ allowlist entries go with it (back to 5),
and the reasoning is recorded in the guard itself so the next person does not
rediscover it by burning a matrix run.

commands/gsd/import.md keeps its #3809 fix — that one is the .cjs form this
PR exists to remove, and it is untouched by any of the above.

* revert(#3809): restore explore.md's Step 1 preamble placement

Running the launcher sync script processed workflows/ and agents/ too, not
just the commands/ directory the run was aimed at, and it MOVED
gsd-core/workflows/explore.md's preamble from Step 1 down to Step 3.

The script inserts into the first bash block that USES gsd_run. explore.md's
Step 1 block only DEFINES it, and that placement is deliberate -- the file
says so on the line above: "Placed in Step 1 rather than Step 3 so declining
the research offer cannot leave Step 5's commit call unbootstrapped."
tests/explore-command.test.cjs pins it.

explore.md carried no #3809 offender, so reverting it costs this fix nothing.
This was collateral from invoking the sync script at all, not from the
COMMANDS_DIR change, which is why the earlier commands/ revert did not catch it.

* fix(#3809): drop the hand-rolled regex escaper CodeQL flagged

CodeQL raised js/incomplete-sanitization (HIGH) on the guard's pattern build:
`SHIM.replace(/\./g, '\\.')` escapes the dot and nothing else, so it does not
escape backslashes. It blocked PR #3815.

The repo already bans this shape -- local/no-adhoc-regex-escape exists exactly
to stop hand-rolled escapers, with the canonical one in src/pattern.cts. Rather
than reach for that helper, the pattern now carries no escaping logic at all:
SHIM is a compile-time constant whose only metacharacter is the dot, so the
regex source is spelled out literally. The generated source string is
byte-identical to what the replace() produced, verified before and after --
0 offenders on this tree, 52 against origin/next, unchanged.

A drift pin asserts SHIM_PATTERN still matches SHIM exactly, and that the dot
is escaped rather than acting as a wildcard, so the two cannot separate.

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.

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.

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

   still claimed interactive runs unconditionally present a
   checkpoint:human-verify. CONTEXT.md and docs/AGENTS.md were updated in 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).

* 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.

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

* 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.

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

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

Two of these pin defects that exist on next today:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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.
