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.

* 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.

* 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.

* 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.

* docs(#3911): document the hook crash-policy contract

Reference and Explanation via a new docs/features fragment (FEATURES.md is
generated from it), INVENTORY rows for the three new hooks/lib files, and an
ARCHITECTURE note on the hooks section.

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.

Refs #3911

* 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

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.

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.

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.

* 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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

Refs #3881

* 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).

Refs #3881

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

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

Root cause was two clobber sites, not one:

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

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

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

Refs #3881

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

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

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

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

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

Refs #3881

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

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

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

Refs #3881

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

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

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

Refs #3881

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

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

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

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

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

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

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

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

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

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

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

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

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).

* test(#3881): ratchet five stale mutation floors and close the frontmatter gap

Raised five module minScore floors per CI run 33012034388 (floor(achieved)-1):
config-schema 75.51%->74, prompt-budget 88.95%->87, context-composer 79.92%->78,
context-utilization 92.31%->91, active-workstream-store 87.42%->86. Updated both
scripts/mutation-matrix.cjs COVERED entries and tests/mutation-matrix-ratchet.test.cjs
RATCHET_BASELINE in the same diff per the ratchet's own contract.

Closed the frontmatter shard's 63.03%-vs-65 gap with new behavioral tests in
tests/feat-3881-yaml-parser-consequences.test.cjs, each paired with a documented
near-miss: frontmatterDeepEqual's array-order/length/type-mismatch/key-order
semantics (via spliceFrontmatter's no-op guard), scalarNeedsDoubleQuoting's
leading/trailing-whitespace and dash/surrogate triggers (via reconstructFrontmatter),
repairAmbiguousColonValues' already-quoted vs ambiguous-colon repair paths (via
extractFrontmatter), and the null-byte sentinel round-trip surviving at region
offset 1. Did not lower minScore.

* test(#3881): decouple the ratchet test from real module floors

The CLI end-to-end rows in tests/mutation-score-ratchet.test.cjs hardcoded config-schema's real floor (52), which commit 973321541 legitimately ratcheted to 74 -- breaking a test pinned to the exact value the mechanism under test exists to change. Add an injectable --matrix seam to scripts/check-mutation-score-ratchet.cjs and point the CLI rows at a synthetic module + synthetic floor built via a temp fixture, so the rows are indifferent to any real module's floor moving while still exercising the same fail/pass behaviour.

A tracked-document sweep of 910 *.md files cannot see this dependent: repairAmbiguousColonValues's one real caller is user hand-edited STATE.md content that never lives in this repo's tree, only on end users' machines, and is pinned by tests/smart-entry.unit.test.cjs. Restores the function plus its post-throw fallback path (loadWithAmbiguousColonRepair) only; repairMalformedInlineArrays and splitLegacyInlineArrayItems stay deleted, reverified against the full frontmatter test shard. Adds a frontmatter-level regression row in tests/feat-3881-yaml-parser-consequences.test.cjs so the dependency is visible where the function lives.

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

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

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

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

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

Verified on the remote runner.

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

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

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

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

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

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

Verified on the remote runner.

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

Binds the approved triage shape before any of it exists:

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

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

Refs #2856

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

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

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

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

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

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

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

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

Verified on the remote runner.

Closes #2856

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

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

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

Verified on the remote runner.

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

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

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

Two findings worth naming:

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

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

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

Verified on the remote runner.

Refs #2856

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

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

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

Only ack what the check actually reports.

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

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

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

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

Closes #2401

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

Independent review found three defects in the recognizer:

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

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

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

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

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

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

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

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

* test(#2401): regenerate golden install-tree fixtures for the new references

Adding two files under gsd-core/references/ changes what the installer

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

325fc25c01 fix(#3569): require a digit-bearing phase id in the stats heading scan (#3591)
* test(#3569): pin stats phase-id shape — inline-code mentions produce no phantom row

Failing-first regression for #3569: cmdStats' heading scan accepted any
word as a phase id, so prose mentioning ### Phase N: inside inline code
inflated phases_total and disagreed with roadmap analyze. New adversarial
fixture phase-heading-inside-inline-code.md (blockquote + bare mention),
parity assertion against roadmap analyze, and over-narrowing guards for
decimal / milestone-prefixed / letter-prefixed ids.

* fix(#3569): require a digit-bearing phase id in the stats heading scan

cmdStats' hand-rolled heading pattern captured any word as a phase id,
so a ### Phase N: token inside an inline code span (the issue's
blockquote) produced a phantom Not-Started row that could never
complete, inflating phases_total and deflating percent forever. The id
capture is now the canonical #3036 shape roadmap.cts uses (digit
required; letter-prefixed, decimal, and milestone-prefixed ids keep
counting), so stats and roadmap analyze agree.

* fix(#3569): sanction the stats id-shape literal; correct zero-padded expectation

Review findings: the phase-id drift guard requires the // phase-id-owner:
comment directly above the regex (same form as roadmap.cts); the
milestone-prefixed over-narrowing guard must expect normalizePhaseName's
zero-padded 02-01 form, not the raw 2-01 token.

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

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

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

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

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

Closes #3560

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

Review findings.

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

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

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

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

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

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

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

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

7976b1ca0d feat(#1689): per-plan agent_hint executor routing (#3417)
* feat(#1689): per-plan agent_hint executor routing

Option A per-plan specialist routing: a plan with an `agent_hint:` frontmatter field is dispatched to that subagent instead of gsd-executor when it resolves on the active runtime; absent/unresolved/disabled falls back to gsd-executor (byte-identical). Default-on via workflow.agent_hint_routing.

- src/phase.cts: parse agent_hint into the plan-index JSON (plan_json.agent_hint)
- agent-install-check.cts: resolveAgentHint() reuses getAgentsDir + runtime filename variants; probes project + global agent dirs; fails closed; rejects path-traversing names
- gsd-tools.cjs: 'resolve-agent' query route (fail-closed to gsd-executor; --raw/--json)
- execute-phase.md: lean per-plan reference + {EXECUTOR_TYPE} placeholder (host stays under the ADR-857 Phase 6 byte ceiling)
- execute-phase/steps/per-plan-executor-routing.md: resolution logic (Agent()-based dispatch; advisory on orchestrator-worktree)
- config: workflow.agent_hint_routing (validKey, default-on via SCHEMA_DEFAULTS, boolean validator)
- docs (CONFIGURATION.md, plan-md.md), changeset, tests/agent-hint-routing-1689.test.cjs (17 tests)

checks; execute-phase still lists the built-in roster incl. gsd-executor.

2076d450d7 fix(#2652): gate quick/diagnose dispatch on dispatch.isolation, not the runtime name (#2728)
* fix(#2652): gate quick/diagnose dispatch on dispatch.isolation, not runtime name

quick.md and diagnose-issues.md kept the pre-#2584 `RUNTIME != "claude"`
worktree gate, so every non-Claude runtime failed closed regardless of the
capability it negotiated — including Codex, which declares
orchestrator-worktree. Route both through the negotiated dispatch.isolation
seam via a new shared reference, and migrate the two execute-phase reference
fragments that carried the same runtime-name gate.

- new gsd-core/references/dispatch-isolation-gate.md: canonical ISOLATION
  resolution, harness-flag resolution, single-agent degrade rule
- quick.md / diagnose-issues.md read the gate; dispatch uses the {harnessFlag}
  placeholder rather than a hardcoded isolation="worktree"
- execute-phase-wave-guard.md / execute-phase-between-wave-reset.md: migrate
  [ "$RUNTIME" = "claude" ] -> [ "$ISOLATION" = "harness-worktree" ]
- every degrade site now clears BOTH USE_WORKTREES and ISOLATION; clearing one
  dispatched an isolated agent with no base guard and no manifest
- parity guard in host-integration.test.cjs scans workflows AND references and
  matches six reintroduction shapes
- migrate four tests that pinned the pre-#2584 runtime-name contract

* fix(#2652): normalize dispatch-site paths to forward slashes for Windows

path.relative() returns backslash-separated paths on Windows, so the
#2652 dispatch-site parity test compared "gsd-core\workflows\quick.md"
against the hardcoded forward-slash literal "gsd-core/workflows/quick.md"
and failed on every windows-latest CI lane. Normalize with
.replace(/\\/g, '/'), matching the existing convention used elsewhere in
this suite (e.g. tests/branch-no-track-guard.test.cjs:37).

* test(#2652): restore the size-growth acknowledgment

The rebase dropped tests/emitted-drift-ack.json. #2757/#2758 fixed the
ATTRIBUTION axis, but the SIZE-GROWTH axis is independent: diagnose-issues.md
(+2086) and quick.md (+230) still need an ack naming them and saying why.

Verified: 65/66 without it (both files named), 66/66 with it.

* fix(#2652): convert execute-plan.md Pattern A onto the dispatch-isolation gate

Pattern A hardcoded `isolation="worktree"` — Claude Code's own literal —
gated only on `workflow.use_worktrees`, with no capability negotiation at
all. It is the same defect #2652 fixes at the other four sites, just a
different shape: the file contains no RUNTIME variable, so the new detector
correctly does not flag it.

Concrete break: a Codex user who follows this PR's own newly-documented
pattern and sets `workflow.use_worktrees: true` to get isolated dispatch via
/gsd:quick then runs a plan through /gsd-execute-plan Pattern A, and hits an
unconverted path — either an Agent() call erroring on an unrecognized
parameter or silent unisolated execution, depending on host tolerance.

Pattern A is a single-agent dispatch site through the host's own subagent
tool, so it takes the same treatment as quick.md and diagnose-issues.md:
resolve ISOLATION/HARNESS_FLAG through the canonical reference, degrade to
sequential on orchestrator-worktree hosts, and substitute the host's declared
{harnessFlag} instead of Claude Code's literal.

while the area was open.

* docs(#2652): add the INVENTORY row for dispatch-isolation-gate.md, refresh CONTEXT

Two bookkeeping gaps flagged in review:

INVENTORY.md had no row for the new gsd-core/references/dispatch-isolation-gate.md.
INVENTORY-MANIFEST.json was regenerated correctly and its --check only diffs a
live directory scan against the committed manifest, so CI passed regardless —
but gen-inventory-manifest.cjs's own stderr guidance says to add the matching
INVENTORY.md row. This is the repo's named "Inventory Drift" pattern. Placed
with the dispatch/isolation cluster (worktree-branch-check, runtime-aware-dispatch)
rather than alphabetically, matching how that table is grouped.

CONTEXT.md's Host-Integration Interface entry still described dispatch.isolation
as "declared and negotiated but not yet consumed by any scheduler — Phase 1 of
#2584". That was already stale before this PR (execute-phase graduated in Phase 3)
and more so now with three single-agent dispatch sites consuming it.

* test(#2652): detect reversed-operand runtime gates; add a permutation property

All five reintroduction regexes assumed $RUNTIME on the LEFT of the
comparison, so `[ "claude" != "$RUNTIME" ]` — the same gate written
backwards — evaded every one of them. Verified against the old patterns
before fixing: all four reversed shapes (single bracket, double bracket,
test builtin, JS template) scored EVADED.

Each comparison shape is now generated in both operand orders from a single
template, so a shape cannot be added in one order and forgotten in the other.
The mutation table gains the four reversed cases.

Also adds the fast-check property review suggested in place of the hand-rolled
cases: it generates the cross product of the axes an author actually varies —
bracket form, operator, operand order, quoting, spacing, runtime id — so a
permutation the hand-written patterns miss surfaces here rather than in
production. The 11 explicit cases stay as named regression anchors.

execute-plan.md joins the scan's required-identities list now that it is a
converted dispatch site.

* test(#2652): repin the execute-plan.md PROSE_ALLOWLIST line after the rebase

The #2751 command-position gate pins its prose exemptions by line number.
This branch inserts the dispatch-isolation resolution above the
`validated downstream by gsd-tools uat classify-coverage` sentence, moving
it from execute-plan.md:387 to :397 — which fired the gate twice for one
displacement (an un-allowlisted mention at 397, a stale entry at 387).
The prose itself is unchanged from next; only the pin moves.

Fixes #2652

* fix(#2652): gate the #2649 base-check on ISOLATION in diagnose-issues.md

The rebase onto next merged #2649's pre-dispatch base-check textually, but
its degrade flipped USE_WORKTREES after ISOLATION was already resolved, so
the degrade never reached the dispatch decision. Gate the block on
ISOLATION = "harness-worktree" and degrade ISOLATION itself, the same
pairing quick.md already uses.

* fix(#2652): key quick.md post-dispatch bookkeeping on ISOLATION, not the Claude literal

Review Blocker: the manifest append (l.822), worktree merge-back (l.825), and
its skip clause (l.839) all conditioned on the literal isolation="worktree" —
Claude Code's own rendering of {harnessFlag}. Cursor renders --worktree, so a
newly-unblocked isolated Cursor run created a worktree whose committed work
was never merged back and never cleaned up, silently. All three now key on
ISOLATION = "harness-worktree" at dispatch.

The existing parity detector cannot catch this class (its ISOLATION_TOKEN
treats the literal as a legitimate marker), so this adds a dedicated
literal-condition detector with a discrimination proof against both pre-fix
sentences, a benign-mention control, and a positive pin on all three
re-keyed conditions. Verified fail-first against the pre-fix quick.md.

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

* fix(#2652): scope the use_worktrees=false install stamp to isolation=none runtimes

`_stampNonClaudeRuntimeDefaults` rewrote every non-Claude runtime's
`workflow.use_worktrees` read to `--default false`. That default resolved
before `gsd_run query dispatch-isolation` was ever consulted, so the five
runtimes that declare worktree support — cursor (harness-worktree) and
codex/opencode/kimi/kimi-code (orchestrator-worktree) — got ISOLATION=none
regardless of what they negotiated. The gate this PR migrates dispatch onto
was therefore still deciding isolation by runtime name, one layer down.

The stamp's #1521 premise was that worktree isolation *was* Claude Code's
isolation="worktree" spawn parameter, which no other host honored. #2584
replaced that premise with the negotiated capability. The stamp is now scoped
to runtimes whose negotiated isolation really is `none`, where the default it
writes is the outcome the resolver reaches anyway.

`_negotiatedDispatchIsolation` mirrors routeDispatchIsolation's resolution
against the same registry — closed vocabulary, a harness-worktree host must
declare its flag, an orchestrator-worktree host must carry a descriptor that
resolves — and fails closed to `none` on anything else, so an undeclared or
unknown runtime keeps today's behavior.

Two #1515 tests pinned the superseded premise for codex and are re-pointed at
the new contract rather than deleted: the safety property they protect is now
held by the isolation gate's fail-closed resolution, not by a name-scoped
install-time default. Verified fail-first — all five assertions red against
the pre-fix source, green after.

* test(#2652): acknowledge the emitted ripple and re-point the end-to-end stamp proof

Scoping the use_worktrees stamp changes emitted output, and two gates caught it.

`gsd-core/workflows/execute-phase.md` now differs at emit time for the five
hosts that declare worktree support (cursor harness-worktree; codex, opencode,
kimi, kimi-code orchestrator-worktree) — the source file is byte-identical, only
the stamp is gone. Acknowledged in this PR's fragment.

`tests/install.test.cjs`'s real-install assertion pinned the superseded premise
end-to-end, asserting codex receives `--default false`. Re-pointed rather than
deleted, matching the two unit tests: it now proves codex keeps the unstamped
`true` read. A second arm installs windsurf — which declares isolation `none` —
and asserts the false stamp is still applied there, so the change cannot
silently degrade into "never stamp" without a test noticing.

The ack entry collides with `2658-trae-instruction-file-path.json`, which is
fully spent (merged via #2925, so all 25 of its entries are present at base and
gate nothing) and is pruned for the same reason and by the same rule as the
spent `2649-*` fragment this PR already removed. #2566 prunes the same file for
the same collision on `new-project.md`; a delete/delete merges cleanly either
way, and the base-side cleanup would make both unnecessary.

* fix(#2652): re-record the sentinel when a dispatch site degrades isolation

Review Blocker B1/B2/B3. Every isolation degrade in a dispatch site is decided
in shell, where routeDispatchIsolation cannot see it. That resolver persists
whatever it resolved to the run-scoped sentinel as an unconditional side effect
(#3045), so a degrade that only reassigns $ISOLATION leaves the sentinel
asserting harness-worktree while the dispatch correctly omits the harness flag.
The shipped PreToolUse guard reads the sentinel at the instant of the Agent()
call and denies that mismatch with exit 2 — the work does not run unisolated,
it does not run at all. Latent on this branch and lands on rebase, since
8f75e275 (#3045) is not yet in the merge-base.

Four sites now push the final shell-computed value through the same single
write path with --force-isolation, matching the idiom #3045 established in
executor-isolation-dispatch.md:

  - quick.md, after the #1941 base-check degrade
  - diagnose-issues.md, after the config-gate degrades and after #2649's
  - execute-plan.md Pattern A, before spawning
  - references/dispatch-isolation-gate.md, both degrade paths, plus a new
    "Re-record after every degrade" section — the canonical file taught the
    defect, so fixing only the call sites would leave the source of truth wrong

Tests assert the RECORDED value, not $ISOLATION. Asserting the local variable
is what let this class through: $ISOLATION was already `none` at every site and
the defect was entirely in what reached the sentinel. Each workflow's own
degrade block is executed under a gsd_run stub that captures the write, with a
fail-first proof that the pre-fix shape records nothing (while $ISOLATION reads
`none` in both), plus a coverage guard so a new degrade site cannot skip it.

Also corrects the drift-ack rationale (review Minor 5): @-references are
eagerly inlined, so extracting the gate does not reduce loaded context. The
reason to extract is single-sourcing across five dispatch sites.

* fix(#2652): restore next's 2658 ack fragment, minus the one colliding key

trek-e (PR #2728, 2026-08-07): the branch deleted
tests/emitted-drift-acks/2658-trae-instruction-file-path.json wholesale
while next had modified it. That was correct against the 08-03 base, where
the fragment was fully spent; it is wrong against next @ 1d208e5a, which
still carries 23 live entries.

next's copy is restored byte-identical except for the single key that
genuinely collides with this PR's own fragment,
gsd-core/workflows/execute-phase.md. Both acks name that path for
different deltas -- 2658's is the trae CLAUDE.md replacement-target
rewrite, ours is the emit-time _stampNonClaudeRuntimeDefaults ripple from
review round 3. Per the ack-lifecycle law (#2789), an entry already at the
base is spent and inert, so this PR's entry is the live one and 2658's is
dropped.

This follows the guidance given on #2566 in the 08-06 round: "Regenerate
rather than delete -- the collision is one entry."

Verified: lint-emitted-drift-ack ok (0 problems, 357 keys, no cross-source
duplicates); emitted-attribution 170/170 with GSD_EMITTED_BASE=upstream/next;
host-integration 222/222; runtime-converters 130/130.

* fix(#2652): bound the degrade-harness spawn and close the round-6 majors

B1 (CI red, ours): tests/host-integration.test.cjs spawned bash with no
timeout, violating local/no-unbounded-spawn. `next` deleted the allowlist
outright (#3148), so the merge-commit run flags it even though this branch
still carries the file's grandfathered entry. Bounded at 15s, with a named
failure on timeout/signal rather than an opaque `exited null`.

M1: add a parity test between `_negotiatedDispatchIsolation` (install time)
and `routeDispatchIsolation` (dispatch time). Both read the same capability
registry and the same `resolveOrchestratorExec`, but duplicate the DECISION
on top of them across two surfaces with no call edge between them, so neither
symbol appears in the other's impact graph and nothing static can catch them
drifting apart. The resolver leg drives the real gsd-tools CLI per registered
runtime, both ways it is really called: with `--cwd-target` (the executor
spawn, which resolves the orchestrator descriptor — the same question install
time asks) and without it (the `Resolve ISOLATION` call every dispatch site
makes first, which does not). The second leg is what catches an orchestrator
host whose descriptor stops resolving: the install would stamp
`use_worktrees=false` while the workflow gate still reported
`orchestrator-worktree`.

M2: add install-level Cursor coverage. A real `--cursor` install, then the
gate blocks that install emitted, run against the gsd-tools that install
emitted, with the runtime declared through `.planning/config.json` — the tier
`resolveRuntime` actually reads — and any ambient GSD_RUNTIME blanked, so the
install has to reach the right resolver on its own. It then performs the
documented `{harnessFlag}` substitution against the `Agent()` call that
install emitted and asserts on the rendered dispatch: exactly one emitted
Agent() call carries the slot, it is the gsd-executor / gsd-debugger dispatch
rather than some other call in the same file, and rendering it yields
`--worktree` with no residual placeholder and no `isolation="worktree"`.
This is artifact-level — it proves the emitted wiring, not a live Cursor
host invocation. Asserting the shell variable alone would have stayed green
if the placeholder were deleted from the emitted dispatch, or drifted onto
the reviewer call beside it.

M3: diagnose-issues.md inlined a reordered copy of the reference this PR
introduces as the single source of truth. It now reads the reference the
same way quick.md and execute-plan.md do; the drift-ack entry is corrected
to describe what the file actually contains, and to name the four files that
reference the gate rather than claiming five.

M4: CONTEXT.md still called `resolveOrchestratorExec` UNCONSUMED in the same
paragraph this PR edits. It has been consumed since #2584 Phase 3 — routed
through `query dispatch-isolation --json` and process-spawned by
executor-isolation-dispatch.md — and #2652 adds a second consumer.

Every new assertion verified fail-first against a real mutation: cursor's
negotiated isolation (breaks the target-bound parity leg), the no-target
orchestrator branch in routeDispatchIsolation (breaks the gate parity leg),
cursor's harnessIsolationFlag (breaks the resolved value), deleting
`{harnessFlag}` from quick.md's emitted Agent() call (breaks the slot), and
moving it onto the code-reviewer dispatch (breaks the wrong-call guard).

* fix(#2652): serialize unisolated diagnosis, scope the execute-plan gate to dispatching patterns

Round-7 review findings (independent cross-AI pass over the whole PR against
the current base).

BLOCKER — diagnose-issues.md announced sequential mode and then fanned out.
The `orchestrator-worktree` degrade sets ISOLATION=none and prints "debug
agents run sequentially on the main working tree", but the spawn step still
said "All agents spawn in single message (parallel execution)". On Codex,
OpenCode and Kimi that dispatched N unisolated debuggers concurrently against
the primary checkout — the exact outcome the degrade exists to prevent, and
reachable only because this PR removed the FATAL that used to stop those
hosts earlier. Fan-out is now keyed on ISOLATION: parallel only when each
agent has its own worktree, one at a time otherwise.

BLOCKER — execute-plan.md Pattern B could not dispatch at all on Claude or
Cursor. The gate recorded `harness-worktree` to the #3045 sentinel, but only
Pattern A carries `{harnessFlag}`; Pattern B's segment executors carry none,
and `hooks/gsd-agent-isolation-guard.js` blocks precisely that mismatch with
exit 2. Segments are unisolated BY DESIGN — each continues on the working
tree the previous one left behind, so per-agent worktrees would break the
sequence — so Pattern B now records `none` before its first dispatch and
dispatches without the flag.

MAJOR — the same gate ran before routing was chosen, so an isolation-`none`
host with `use_worktrees=true` hit the fail-closed FATAL even when routing
would have selected Pattern C, which is fully inline and dispatches nothing.
Resolution now happens after the pattern is known, and Pattern C skips it.

MAJOR — tests/host-integration.test.cjs fed `fs.readFileSync` output straight
to bash. The `\r?\n` fence regex guards only the delimiter, leaving embedded
CR on every line of the captured body — DEFECT.WINDOWS-CRLF-TEST-PORTABILITY,
which helpers.cjs documents by name. Now reads through `readFileNormalized`.

MAJOR — the "every dispatch-site degrade block re-records" test hand-listed
three files, so its name was a claim its scan could not support. The scan is
now derived from the workflow/reference tree (SCAN_ROOTS/collectMarkdown
hoisted to module scope so there is one definition, not two). Verified
fail-first against execute-plan.md — a file the previous scan never opened.
The two wave fragments are exempt because they delegate the re-record to
per-plan-worktree-gate.md via USE_WORKTREES_FOR_PLAN; that delegation is now
ASSERTED, so deleting the delegate fails this test instead of widening a hole
silently.

MINOR — the changeset claimed the FATAL was gone for "non-Claude runtimes"
full stop. Narrowed: isolation-`none` hosts still fail closed when worktrees
are explicitly enabled, which is the contract rather than the defect.

Two further findings were investigated and rejected, with evidence:
- Raw `spawnSync` vs `tests/helpers/process-seam.cjs`: the seam exposes
  runNode/runGit/runHook and cannot express the `bash -c` harness these tests
  need; `installAndRead` in this same file is byte-identical to the base and
  still uses raw spawnSync with an explicit timeout, which is the form the
  lint sanctions. Migrating only the new call sites would split the file's
  convention for no safety gain.
- `pending-migration-to-typed-ir` on the runtime-converters parity test: the
  annotation and the rendered-text loop both exist at the merge-base under
  #3090. This PR extends an already-tracked test rather than adding a new one
  under a category CONTRIBUTING closes to new tests.

Refs #2652

* test(#2652): re-point the execute-plan prose allowlist at its shifted line

`PROSE_ALLOWLIST` in tests/no-bare-gsd-tools-command-position.test.cjs keys
entries by LINE NUMBER. The previous commit added the post-routing isolation
block to execute-plan.md, which pushed the `validated downstream by
gsd-tools uat classify-coverage` prose mention from line 397 to 414. That
broke the guard in both directions at once: the entry at 397 went stale, and
the real mention at 414 became an unallowlisted offender.

Caught by CI (7 red jobs, all shard 3/3 plus ubuntu-22) rather than locally,
because I verified only the suites I believed the change touched. Any edit to
a workflow .md shifts line numbers, and this repo carries line-keyed
allowlists — so a workflow edit needs the full suite, not a subset.

Refs #2652

* test(#2652): route the new subprocesses through the process seam

Retracting a rejection I made on the record. In the round-6 response I
argued these call sites could keep a hand-rolled `spawnSync` because the
seam exposes only runNode/runGit/runHook and cannot express `bash -c`, and
because `installAndRead` in the same file uses that shape. The first half
was true and irrelevant, the second half is not a licence: CONTRIBUTING is
unambiguous — "Anything that shells out goes through
tests/helpers/process-seam.cjs — never a hand-rolled spawnSync/execFileSync
in your suite", and "Never use try/finally inside test bodies."

`runHook` already documents `interpreter: 'bash'` for running a shell
script, so writing the harness to a file complies without extending the
seam. I had the rule and the seam's own documentation in front of me and
reasoned around both.

Converted:
- host-integration.test.cjs degrade harness: spawnSync('bash', ['-c', …])
  → runHook(scriptFile, [], { interpreter: 'bash' }).
- install.test.cjs cursor gate: `which bash` probe → process.platform;
  the installer spawn → runNode(…, { env: installSpawnEnv({HOME,
  USERPROFILE}) }), which also blanks ambient GSD_HOME/runtime-location
  vars that could otherwise make capability discovery host-dependent;
  the emitted-gate spawn → runHook(gateScript, [], { interpreter: 'bash' }).
- Three try/finally test bodies → t.after().

Class-norm timeouts: tests/helpers/timeouts.cjs arrived with this branch's
latest base merge, so the literals written earlier (15000/120000/60000) now
duplicate PROBE_TIMEOUT_MS and INSTALL_TIMEOUT_MS. Imported instead — that
module exists because INSTALL_TIMEOUT_MS had already drifted 60s→120s once
after a real bench ETIMEDOUT.

Deliberately NOT converted: `installAndRead`'s spawnSync, which is
byte-identical to the merge-base and predates this PR — converting shared
scaffolding is an unrelated change.

Verified equivalent, not assumed: argv/cwd/env/encoding/timeout and every
assertion are preserved; t.after() still cleans up on the assertion-failure
path the try/finally covered; and the cursor test still resolves Cursor
under a hostile ambient GSD_RUNTIME=claude.

Refs #2652

* fix(#2652): replace the falsified use_worktrees doc row; distinguish an unresolvable gate from a declared none

Round-8 review findings.

BLOCKER — docs/CONFIGURATION.md's `Non-Claude note` asserted three things
this PR overturns: that worktree isolation "no other runtime honors"
(Cursor declares harness-worktree with `--worktree`, and this PR's own
install test asserts that flag reaching the emitted Agent() slot), that
non-Claude installs default the key to `false`, and that forcing `true`
always fails closed. Replaced with the capability-based description, and
the `#1515, #1521` citation dropped — those are the two issues whose
premise this PR removes.

The reviewer flagged that the fix is merge-order dependent, because #2531
rewrites the same row and its replacement text is written in anticipation
of this PR landing. Rather than pick an order, BOTH sides are now
order-independent: #2531's "Current default … until #2652" paragraph
becomes a plain troubleshooting note, and this row states the capability
rule without asserting a stamp state. Whichever merges first, the row is
correct; the second merge is a textual conflict at worst.

MINOR — the gate reported a capability verdict the tool never returned.
`ISOLATION=$(… || echo "none")` made a shim-resolution failure, a non-zero
exit and an empty stdout indistinguishable from a declared `none`, so a
transient query failure aborted /gsd:quick on Claude Code with "runtime
'claude' declares no executor-isolation primitive" — false. The gate now
tracks ISOLATION_RESOLVED separately: both paths still fail closed, but only
a real verdict claims the host declares nothing; the unresolved branch says
it could not resolve and points at the shim. Fixed in the canonical
reference so every dispatch site inherits it.

MINOR — quick.md:527 cited #2649 for its own degrade; that is #1941, and
#2649 is the diagnose-issues/execute-plan gate. Corrected, and the
distinction stated so the next reader does not chase it.

MINOR — quick.md:413 (manifest init) and :429 (worktree_branch_check embed)
still branched on USE_WORKTREES while dispatch, manifest-append, merge-back
and the skip clause had all moved to ISOLATION. Safe only by coincidence —
both now key on ISOLATION.

MINOR — the diff removes a second drift-ack entry (the execute-phase.md key
from 2658-trae-instruction-file-path.json), forced by the same duplicate-key
lint rule as the 2649 removal. Disclosed in the PR comment; the earlier
disclosure covered only one of the two.

Verified: lint:ci green; 300/300 across host-integration,
fix-1941-quick-worktree-stale-base, execute-phase-wave and workflow-guard.

Refs #2652

* test(#2652): anchor the emitted-gate finder on the heading, not the assignment

`b89c3fbf` added a finder that located the gate's `Resolve ISOLATION` block by
the literal `ISOLATION=$(gsd_run query dispatch-isolation --raw`. `f3bccf21`
then split that assignment into `_ISOLATION_RAW`/`ISOLATION_RESOLVED` so a shim
failure stops masquerading as a declared `none` — and the finder stopped
matching. The test did not report the drift it exists to catch; it reported
"emitted dispatch-isolation-gate.md has no Resolve ISOLATION bash block" and
went red, and stayed red because the earlier full-suite run was read from a
truncated log.

Anchored on the heading instead. The workflows tell a dispatch site to run the
`Resolve ISOLATION` and `Resolve the harness flag` blocks BY NAME, so the
heading is the contract and the body is free to change under it.

Verified: 413/413 in tests/install.test.cjs. The test still bites — mutating the
gate's `ISOLATION="$_ISOLATION_RAW"` to `ISOLATION=none` turns it red (the
emitted gate then resolves cursor to none and exits 1 instead of printing
harness-worktree), and reverting restores green.

* fix(#2652): wire the canonical resolver at the one dispatch site that still inlined the old shape

Codex review of the whole PR on the new base found one Major, and it was real.

executor-isolation-dispatch.md declares references/dispatch-isolation-gate.md
canonical at line 10, then kept the OLDER resolver inline: `|| echo "none"`, no
ISOLATION_RESOLVED. So the one site that resolves isolation for the wave path
collapsed a shim failure into a declared `none` and aborted with "runtime
'$RUNTIME' declares no executor-isolation primitive" — false for a Claude or
Cursor user whose resolver merely failed to answer. Still fail-closed, so not an
unsafe-dispatch hole, but the correction this PR is about was unwired at the
site that matters most.

Replaced with the gate's exact shape: capture the raw value, track
ISOLATION_RESOLVED, and emit the "could not resolve" FATAL when no verdict was
learned.

Added a regression test in the #2652 dispatch-site parity suite: every file that
ASSIGNS from `gsd_run query dispatch-isolation --raw` must carry
ISOLATION_RESOLVED, must not use the collapsing form, and must have a distinct
unresolved message. Nothing covered this before — install.test.cjs checks the
emitted REFERENCE, not each site's own inline copy, which is exactly how the two
drifted apart.

The test's first draft also flagged quick.md, diagnose-issues.md and
execute-plan.md. That was a false positive worth recording: those three
@-reference the gate and only make `--force-isolation` re-record calls, which
carry no verdict. The predicate now matches an assignment from the resolver, not
any mention of it, so it flags sites that can actually be wrong.

Verified by mutation: restoring the collapsing line reds the new test.

Validated: lint:ci clean; full suite shows the same 7 known failures as the
pre-change baseline — #1160 _resolveManifest and the #3053 quick_id
host-timezone tests (both reproduce on pristine next @ 33fca50d), plus
helpers-cleanup "outside os.tmpdir()", which fails only in a worktree.

* test(#2652): close two vacuous-pass holes in the new inline-resolver guard

Codex cleared the push and flagged the guard test itself. Both holes were real.

SCAN_ROOTS already yields references/dispatch-isolation-gate.md, and the test
appended it a second time, so the candidate list was [executor, gate, gate] and
`length >= 2` was satisfiable by the gate alone. If the executor site had
dropped out of the predicate — the exact regression the test exists to catch —
it would still have passed. Paths are deduped and the assertion now pins the two
expected inliner identities instead of a count.

The collapse detector keyed on `ISOLATION=$(…)`, so `_ISOLATION_RAW=$(… || echo
"none")` restored the identical defect while satisfying every other assertion
(ISOLATION_RESOLVED still appears in the file). Codex mutation-probed exactly
that and it passed. The pattern now matches any assignment target and any
`|| … echo` tail. Verified: that mutation now reds the test.

Test-only change; the workflow bash is byte-identical to the commit the full
suite ran green against. lint:ci clean, host-integration 223/223.

7a7bf19fc1 enhance(#2872): record scope and runtime in the install manifest (#3323)
* enhance(#2872): record scope and runtime in the install manifest

gsd-file-manifest.json gains manifestVersion, runtime and scope, and a new
read-only Installed Surface Resolver Module reads both install scopes for a
runtime in one call -- the first code path in the repo that does.

Phase 3 of epic #2866 (ADR-2866). Blocks Phase 4 (#2873), which resolves
#2218: the resolver's shadowedBy field is that defect expressed as a value
for the first time. It ships computed-and-unread here.

Installed-ness is decided by manifest PRESENCE, never by the new fields, so
a manifest written by an older GSD stays fully functional and no user needs
to reinstall. Recorded runtime/scope are corroboration: a disagreement with
the probed config dir is reported as declaredScopeMatchesProbe: false, never
silently corrected.

readInstallManifest is widened additively -- version/timestamp/mode/files
keep their exact names, types and meanings for all four existing callers.
manifestVersion is a new field rather than a reinterpretation of version,
which holds the package version and is read by the golden-parity fixtures.

Stems are derived from the installed manifest's own file keys, the inverse
of Phase 2's filename composition, guarded by a fast-check round-trip
property plus a kebab-case charset check so a crafted manifest key cannot
put a traversal segment, control character or ANSI escape into a trigger
that Phase 4 renders back to the user.

Also fixes two defects found while working:
- bin/install.js hardcoded manifestVersion: 2 while the reader owned
  MANIFEST_SCHEMA_VERSION = 2. Now single-sourced, with a parity test.
- docs/installer-migrations.md documented an install-state schema of five
  snake_case fields that have never been written; InstallState has only ever
  been { schemaVersion, appliedMigrations }. Corrected with a dated note.

Verification runs on the remote runner.

* fix(#2872): fold review findings from three independent engines

Standards axis:
- convert the manifest-schema suite from a hybrid setup(t) closure to
  beforeEach/afterEach (CONTRIBUTING.md:319-354 Pattern 1). The hybrid was
  neither approved pattern and a new test forgetting the call got no warning.
- SCOPE_ORDER was declared twice with no parity test -- this repo's recorded
  generative-fix-divergence class. Give the ordering one owner: install-scope
  exports it frozen, the layout module and the resolver both import it, and a
  test locks it against scopeRank so the constant and the ranks cannot drift.
- drop the defaultReadManifest passthrough (Middle Man).

Spec axis:
- add the VOLATILE_FILES exclusion test and source comment the acceptance
  table promised and did not deliver. gsd-file-manifest.json stays excluded:
  the new fields are deterministic, but timestamp -- the original reason --
  is unchanged.

Security axis:
- bound the reported manifest runtime at 64 chars, matching the
  truncatePostureValue convention already used in this subsystem. It reached
  declaredRuntime unbounded while the adjacent stems were gated by SAFE_STEM;
  an inconsistent posture on the same attacker-influenceable document. The
  charset stays ungated on purpose -- declaredRuntimeMatchesProbe needs to see
  the real value -- so Phase 4 must sanitize before rendering, recorded in the
  design's Known limits.

Both new parity tests were verified to FAIL when the two sides are made to
disagree, then pass again on revert. Verification runs on the remote runner.

* chore(#2872): backfill changeset pr number to 3323

* fix(#2872): give git fixture construction its own timeout class

PR #3323's full test (windows-latest, 22, shard 2/3) failed with

  gitOrThrow: 'git init' failed -- outcome=timed_out exitCode=null
  gitOrThrow: 'git commit --allow-empty' failed -- outcome=timed_out

from drift-detection.test.cjs's beforeEach, a file this branch never touched.
Every other lane passed the same commit, including windows-latest node 24 on
all three shards, and next is green.

Root cause is a bound sized for the wrong class. DEFAULT_GIT_TIMEOUT_MS is
15000 and its own comment scopes it to plumbing READS -- rev-parse, branch,
log -- against an existing repo. createFixture uses it for six sequential
repo-CONSTRUCTION spawns: init, three config writes, add -A, commit. init and
commit each write dozens of files, and on Windows every spawn is
Defender-scanned. Sibling tests in the failing block took 15.6-22.0s against
a 15000ms bound.

This repo already diagnosed this exact shape once: timeouts.cjs's
HOOK_FANOUT_TIMEOUT_MS records PR #3285 failing in the SAME job with the SAME
outcome=timed_out exitCode=null signature at the SAME bound while every other
lane passed, and concludes 'a bound sized for the wrong class, not a slow
machine'. It was fixed by splitting out a heavier class-norm at 60000. Same
remedy here: GIT_FIXTURE_TIMEOUT_MS = 60000, 4x the bound that failed and half
INSTALL_TIMEOUT_MS.

DEFAULT_GIT_TIMEOUT_MS deliberately stays at 15000 -- a blanket raise would
stop a genuinely hung plumbing read from surfacing fast.

Verified the value reaches the spawn rather than being an ignored option:
spawnSync was monkeypatched before requiring the fixture module, and all six
git construction calls were captured carrying timeout: 60000.

This branch's two new test files shift shard composition, which is how a
pre-existing fragility landed in the heaviest shard on the slowest lane.
Fixed here rather than deferred, per the no-defer rule.

Verification runs on the remote runner.

4a1ed2531f enhance(#3242): validate codex .toml model posture, not just presence (#3290)
* test(#3242): failing-first suite for the codex posture health-check

Specifies ADR-2313 D6 before the implementation exists, so the tests
bind to the contract rather than to whatever the code happens to do.

RED is established by construction, not by a remote run:
checkCodexModelPosture and POSTURE_REASON are absent from the compiled
lib today, so every row fails on the missing export. A remote checkpoint
here would prove only that the function is missing, which is already
known — so the run is deliberately deferred to the combined green
checkpoint rather than spent proving a tautology.

That makes the NEGATIVE PROOFS the rows that carry real signal. Every
positive row passes even for a naive implementation that greps
/model\s*=/ over the whole file. Six rows fail it: light-tier
service_tier/model_verbosity decoupling (#774), hand-added keys, a
commented pin, the model_verbosity key-prefix collision, the runtime
no-op ordering, and the headline case — a literal `model = "sonnet"`
inside the developer_instructions ''' block, which the emitter fills
with agent prompts that discuss models constantly.

Row 14's fixture was verified to discriminate before being written: a
whole-file scan matches it and a header-slice scan does not. Without
that check the test would pass trivially and prove nothing, which is the
vacuous-test failure this epic has already hit repeatedly.

Adversarial TOML fixtures are hand-authored against the real Codex shape
rather than generated by generateCodexAgentToml, per #2371 — a fixture
from the writer can only confirm what the writer already believed.

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

* feat(#3242): validate codex .toml model posture, not just presence

Implements ADR-2313 D6. checkCodexModelPosture is a new sibling export,
not a branch inside checkAgentsInstalled — that function carries 33
upstream dependents, cyclomatic 25, and sits in two traced process
flows, so it is deliberately left untouched.

It imports isAnthropicFlavoredModel from model-catalog, a genuine leaf.
That is what Phase 1's constant move bought: agent-install-check is
documented as pure read/verify and imports only leaves, so reaching the
rule through model-resolver would have dragged config-loader into it.

Reads liberally, judges strictly, and never guesses. Tolerates comments,
key order, whitespace, CRLF, and a BOM; anchors on full key names so
model_verbosity does not satisfy a `model` probe; treats extra
hand-added keys as none of its business, since the check is a predicate
on the two fields the posture owns rather than a whitelist over the
document. An unreadable file becomes a named violation and the loop
keeps going.

The scan covers only the header slice — the lines before the
developer_instructions ''' marker. The emitter writes agent prompts into
that block and GSD's prompts discuss models constantly, so a whole-file
scan reports violations for prose. This is the highest-risk defect in
the phase and the reason its fixture was verified to discriminate before
being written.

The non-codex short-circuit runs before any filesystem call, so a stray
.toml under another runtime is never inspected.

Wired through cmdValidateAgents as an additive codex_posture key, so a
violating install is visible from a command a user actually runs rather
than only from a library nothing calls.

Also fixes a test defect found while implementing: .gitattributes forces
`* text=auto eol=lf` repo-wide, so the committed CRLF fixture was
normalized to LF in the index — `git ls-files --eol` reported `i/lf
w/crlf`, the working copy being stale pre-normalization bytes. The CRLF
row was asserting against a file that could not survive a fresh clone.
CRLF is now derived at runtime, which puts it under the test's control
rather than git's, instead of adding a .gitattributes exception that
fights a deliberate repo-wide policy and that anyone could re-normalize.

* docs(#3242): document the codex posture check where a user will look

Three quadrants, filed by where the reader actually arrives.

How-to (recover-and-troubleshoot.md, under Install and update problems)
is titled by the SYMPTOM — "If Codex agents fail to spawn with a 400
about an unsupported model" — and opens with the verbatim error string.
Someone hitting this does not know the words "posture" or "ADR-2313";
they have a 400 in their terminal and will search for that.

Reference (COMMANDS.md) had no `validate agents` entry at all, though
sibling gsd-tools subcommands are documented. Adding user-visible output
to an undocumented command and then linking to it from the new how-to
would have left a dangling reference. The entry carries the
violation-reason table, since the frozen POSTURE_REASON enum is the
machine-readable contract a reader needs rather than the prose.

Both surfaces state that presence and posture are separate verdicts — a
missing agent lands in `missing`, never as a posture violation. That is
a deliberate design decision and would otherwise be invisible to someone
watching one command emit both.

Explanation stays in ADR-2313, which already covers D6 and the
liberal-parse/strict-judge boundary. Pointing at it beats duplicating it
into COMMANDS.md and creating two copies to drift.

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

* fix(#3242): close two false negatives in the posture scan

Both found by an isolated reviewer and reproduced before fixing. Both
made the check report clean when it was not — the worst direction for
this function, since the how-to tells users an empty violations list
means the install is posture-clean.

A quoted TOML key was never matched. `"model" = "sonnet"` is legal TOML,
but the key pattern required a bare identifier, so the pin was silently
invisible. Bare, "double" and 'single' quoted forms now normalize to the
same key name.

The block marker was found by unanchored whole-content search and used
to truncate the header. A `description` value merely containing the
literal text `developer_instructions = '''` truncated the scan before a
real pin, and a user who hand-reordered `model` to sit after the block —
still legal TOML — was never scanned at all.

Fixed by changing the strategy rather than the regex: find the block's
range, anchored at line start, and scan every line OUTSIDE it. That
covers both failures and is strictly more correct than truncation, while
still never reading prompt prose. An unterminated block excludes the
rest of the file, which fails toward a false positive — the safe
direction, since misreading prose as a pin wastes a user's time while
the alternative hides a real one.

Also corrects two overclaims of mine. The how-to named "v1.11", a
version that does not exist — package.json is 1.10.0 and unreleased — so
it now describes the boundary by behavior and links the ADR. And the
test matrix asserted that a naive whole-file scan "fails exactly rows
12,13,14,15,16,25"; the reviewer computed that rows 12, 13, 15 and 16
produce the correct result against that baseline too. They guard real
but *different* mistakes, and the matrix now says which one each catches
instead of attributing them all to the header-slice defect.

* fix(#3242): skip symlinked agent files instead of following them

Security review finding. The scan listed entries with readdirSync and
read them with readFileSync, which follows symlinks — so a symlink in
the agents directory pointing anywhere would have its contents read, and
any line matching the model pattern echoed into cmdValidateAgents'
output through the `value` field. A read-and-echo primitive on an
arbitrary path.

It needs write access to the agents directory, so it crosses no new
trust boundary today. Fixed anyway, for two reasons.

This repo already does it correctly next door: cmdEffortSync filters
with lstatSync().isFile() and the comment "Skip symlinks — only write
regular files to avoid clobbering symlink targets." Being inconsistent
with a sibling in the same subsystem IS the defect.

And Phase 3 (#3243) extends that same cmdEffortSync to WRITE these
files. Establishing symlink-following as the house pattern for Codex
.toml handling here would hand Phase 3 a worse starting point while it
writes rather than reads.

Skipped silently rather than reported, matching the sibling: a symlinked
agent file is a structural install choice, which checkAgentsInstalled
owns, not a model-content posture defect. An lstat that itself throws
excludes the file rather than crashing the scan.

That does narrow the guarantee slightly, so the how-to now says an empty
list means every REGULAR .toml is clean, and tells anyone symlinking
their configs to check the targets by hand. Claiming a clean bill of
health over files the check declined to open would be the same kind of
false confidence the two false negatives above produced.

4b69dc346b fix(#2725): repoint the pre-commit alias guard at sources git can actually stage, drop nine dead ones (#3273)
* test(#2725): failing-first coverage for the inert pre-commit alias guard

Replaces two stale tests that asserted on `sdk/src/query/command-manifest.phase.ts`
— a path retired with the SDK boundary (ADR-0174), so both passed forever while
guarding nothing.

The new matrix drives .githooks/pre-commit through its GIT_OVERRIDE/NPM_OVERRIDE
seams and asserts on the real tracked sources the drift checker reads. Red until
the guard is repointed off the gitignored build outputs it currently watches.

* fix(#2725): repoint the pre-commit alias guard at sources git can actually stage

`.githooks/pre-commit` carried ten staged-path guards and not one of them could
do its job.

Nine anchored on `^sdk/…`, a tree retired by ADR-0174, and invoked npm scripts
that no longer exist (`check:state-document-fresh` and eight siblings). Their
only reachable behavior was to abort the commit with `Missing script` — which
required matching a path that cannot exist, so they were dead twice over.

The tenth was the real defect. Its npm target does exist, but it matched
`^gsd-core/bin/lib/command-aliases\.cjs$` — a gitignored build output
(.gitignore:172). An ignored path never appears in `git diff --cached
--name-only`, so the guard was not stale, it was structurally unmatchable: it
watched the derived layer instead of the source layer, from the day it was
written.

Repointed at the nine tracked `src/*.cts` sources `scripts/check-alias-drift.cjs`
actually reads. The family table moves to `scripts/lib/alias-drift-families.cjs`
so the checker and the hook derive their surface from one list, and a new parity
test fails if a family is added to the checker without the hook learning to watch
its source — the rot mechanism, not just this instance of it.

Matching is now `grep -Fxqf` (fixed strings, whole line): exact path equality,
no regex anchors to get wrong as the list grows. Staged paths are collected into
a variable before matching, because `grep -q` exits on first match and would
SIGPIPE its upstream, which under `set -o pipefail` turns a successful match into
a non-zero pipeline status.

The two CONTRIBUTING.md recipes pasted copies of the hook bodies inline — a third
parallel surface, and one that had already drifted: the pre-commit copy carried
the same dead `sdk/` patterns, and the pre-push copy would have overwritten the
committed hook with a paraphrase that drops the GIT_OVERRIDE seam its test drives.
Both now just point git at the committed files. The pre-push recipe's
`'@example-corp\\.com$'` also never matched anything — inside single quotes bash
keeps both backslashes.

`.githooks/pre-push` was audited for the same rot and has none: it keys on no
paths, no-ops unless GSD_BLOCKED_AUTHOR_REGEX is set, and is covered. Unchanged.

Hooks stay opt-in. Nothing registers `core.hooksPath` for you, per
CONTRIBUTING.md's documented one-time setup.

* test(#2725): make the hook/checker parity assertion bidirectional

Review finding from the isolated adversarial pass: the parity row only caught
the hook UNDER-watching relative to scripts/lib/alias-drift-families.cjs. Drop a
family from the module and the hook would keep watching its source with nothing
to notice — the same divergence class this change exists to close, just pointed
the other way.

The new row takes every `src/*-command-router.cts` on disk as the universe and
asserts the hook stays silent for the eight routers the drift check does not
read. Both directions are now covered by running the real hook, not by comparing
two lists in the test.

Also corrects a CONTRIBUTING.md overclaim caught by the standards pass: 9 of the
11 watched paths derive from the module, not all 11 — bash cannot require a CJS
module, so the hook carries literals and the test is what binds them.

* fix(#2725): ship the shared family table and fix the mock that hid its own rows

Three defects the remote runner caught that local probing did not.

The mock `git` in the regression test emitted its staged-path payload as
`printf '%s' "src/command-aliases.cts\n"`. Bash does not expand `\n` inside a
double-quoted string and printf does not expand escapes in a `%s` argument, so
the mock produced one unterminated line containing a literal backslash-n. No
whole-line match could ever succeed, and every row that expects the hook to FIRE
failed while every row that expects silence passed — which is exactly the
signature the run reported: 9 failures, all of them fire-expecting rows. The
payload now goes through a file the mock `cat`s, which is byte-exact and is what
makes the CR-terminated and empty-staged-list rows mean what they say.

`scripts/lib/alias-drift-families.cjs` was not enumerated in
`GSD_SCRIPTS_LIB_FILES` (bin/install.js:377), so the installer never copied it.
That is not cosmetic: `scripts/check-alias-drift.cjs` ships, and it now requires
this module — an installed tree would have failed with MODULE_NOT_FOUND the
first time a consumer ran `check:alias-drift`. Added to the manifest, which is
what the #3184 install/uninstall parity tests assert against `readdirSync`.

Regenerated the 19 committed install-tree fixtures via `npm run gen:install-tree`
to record the new emitted path. The diff is +1 line per fixture and nothing else.

`npm run lint:ci` exits 0. The earlier claim that `scripts/` is outside the
emitted surface was wrong: `scripts/lib/` is copied into every runtime's install
tree, which is why 19 golden-install-tree cases moved.

342590c70e refactor(#3184): milestone windowing has one owner and a decidable failure signal (#3209)
* test(#3184): failing-first milestone-window single-owner suite

Covers the 50 input classes in the phase test matrix: scope classification
(genuinely-empty vs truncated vs unscoped vs unreadable), the section-end
owner's level boundaries, consumer-output identity per ADR-3180 Decision 4(c),
the milestone.complete refusal with negative proof that no directory moved,
the version-token boundary defect, drift-guard behavior, and three fast-check
properties over document-shaped generators.

Committed alone so the remote runner records the failure before the fix lands.

* refactor(#3184): milestone windowing routes through one owner

Three copies of the milestone section-end walk lived in roadmap-parser.cts —
two distinct computeSectionEnd function nodes plus an inline third in
getMilestonePhaseFilter's versionOverride branch. computeMilestoneSectionEnd is
now the sole owner and the other two are deleted, not kept in sync by comment.

The whole-repo drift guard found what the epic did not: state.cts held three
more re-derivations of the same vocabulary — two byte-identical milestone
bounding checks carrying a defect neither reported copy has (no boundary after
the version token, so v2.0 matched inside v2.0.1), and a milestone-sectioning
predicate. All three route through the owner now.

A composition-level duplicate appeared inside this change's own first pass:
getMilestonePhaseFilter and cmdMilestoneComplete each re-assembled a window out
of the owner's primitives, and had already diverged on whether to skip a closed
milestone heading. sliceMilestoneWindow is the one composition.

Windows now carry the ADR-3180 SCOPE discriminator, so a truncated window is
distinguishable from a genuinely empty milestone — those were output-identical,
which is the whole failure class. roadmap analyze emits it (#3165), and
milestone complete refuses to archive on anything but COMPLETE rather than
pass-all moving every phase directory on disk (#3166). The pass-all degrade is
preserved where its premise holds: making the filter deny-all would trade a
silent over-inclusive answer for a silent under-inclusive one on the read paths
that count with it.

extractCurrentMilestone keeps its signature — 200+ affected symbols across 41
files and 25 process flows — and is a one-line wrapper over the scoped owner.

* fix(#3184): fence-aware phase detection and one heading-selection owner

Review fixes from the two orthogonal passes.

The blocker: hasPhaseEntries matched ATX phase headings fence-aware via
tokenizeHeadings but tested the #2199 bullet form against un-stripped markdown,
so a fenced EXAMPLE of the bullet syntax counted as a real phase. A genuinely
empty milestone then classified TRUNCATED and milestone complete refused a
legitimate archive — a false positive in the destructive direction, worse than
the defect this phase set out to fix. Both that path and getMilestonePhaseFilter
own pre-existing bullet scan now run on stripFencedCode, since leaving one meant
the owner file gave two different answers to the same question.

The selection rule — locate, prefer the non-closed heading, else the first — had
been written three more times inside the file whose thesis is single ownership.
selectMilestoneHeading owns it; all three sites route through it. The copies were
behaviorally identical, so this is de-duplication with no observable change,
verified by probing that all three paths select the same heading.

roadmap analyze emitting a scope no consumer read left #3165's actual symptom
alive, so Route 0 in next.md now treats a non-complete scope as scan-failed
rather than as a clean empty scan, and the ADR amendment no longer overstates
what shipped.

Also: the scope refusal moved above the archive-directory create, so a refusal
leaves nothing on disk; the versionOverride comment names all four consumers;
COMMANDS.md documents the new guard beside its sibling.

* test(#2658): exclude the changelog from the malformed-path scan

The gate walks every emitted .md/.js/.cjs file in an installed tree and asserts
none contains `.claude/.trae/rules` or `.trae/.trae/rules`. CHANGELOG.md ships
into that tree, and its #2658 entry quotes both malformed paths while describing
the fix that removed them — so the release note documenting the fix trips the
fix's own regression test. Red on next before this branch.

The installer is correct: a probe over a real --trae --local install found 621
emitted files, exactly one hit, and it was gsd-core/CHANGELOG.md. The scan scope
was the defect, not the product.

Excluded by exact relative path rather than by loosening the patterns or skipping
all markdown — the emitted agent and command markdown is precisely what #2658 was
about, so the gate stays strong everywhere it matters.

* test(#3184): regenerate install-tree fixtures for the shared drift scanner

scripts/lib/ ships in the npm package and installer, so extracting the shared
tree-walk into scripts/lib/drift-scan.cjs adds one path to every runtime's
install tree. Regenerated via npm run gen:install-tree; the delta is exactly
that one path per fixture.

The two drift guards themselves do not ship (scripts/lint-*.cjs is excluded),
so only the extracted library moves. This matches the existing
scripts/lib/allowlist-ratchet.cjs precedent, which is likewise a lint-only
helper carried in the shipped tree.

* fix(#3184): restore the #730 sub-milestone boundary and narrow the refusal

The remote runner caught two regressions this branch introduced. Both were mine,
and neither review pass found them — only running the existing suite did.

The version-token boundary. I replaced locateMilestoneHeadings' \b with
(?![\w.-]), reasoning that v2.0 matching inside v2.0.1 was the same defect #2562
fixed in isMilestoneShippedInRoadmap. It is not the same question. A milestone
state of v8.0 legitimately selects the '## v8.0-B' sub-milestone section over a
closed v8.0-A sibling (#730), and \b is what allows it while the stricter
boundary forbids it — nine tests in roadmap-phase-fallback said so. Reverted to
\b; the state.cts consolidation is now a straight merge with no behavior change,
and the v2.0/v2.0.1 ambiguity is left exactly as it was. The ADR amendment and
the design doc no longer claim otherwise.

The refusal scope. I refused whenever the window was not COMPLETE, but #3166 is
about the TRUNCATED window specifically — the heading is found and the section
closes before the phase region, so pass-all archives everything. UNREADABLE and
UNSCOPED are pre-existing, legitimately handled states, and refusing on them
broke 'handles missing ROADMAP.md gracefully' and three archive tests. Narrowed
to TRUNCATED; docs corrected to match.

One of the new tests was also wrong: its fixture gave the shipped and current
milestones' phases the same numeric id, and the filter matches on that id, so it
could not have distinguished the two windows. Fixture corrected to exercise what
it claims to.

* fix(#3184): enumerate drift-scan.cjs for uninstall

The installer copies scripts/lib/ wholesale, but uninstall removes an explicit
set — deliberately, so a user's own helpers in that directory survive. The
extracted drift-scan.cjs was copied in and never enumerated, so it outlived
uninstall, left the directory non-empty, and the rmdir that follows failed.

Added to GSD_SCRIPTS_LIB_FILES, following allowlist-ratchet.cjs, which is
likewise a lint-only helper that ships there and is enumerated. Verified with a
real install-then-uninstall into a temp target: scripts/lib/ held exactly the
three GSD files and was gone afterwards.

* test(#3184): assert install and uninstall agree on scripts/lib and scripts/changeset

Found while shipping this phase, and fixed here rather than noted.

install() copies scripts/lib/ and scripts/changeset/ into the target WHOLESALE —
the comment at the copy site literally says "and any future lib helpers".
uninstall() removes them by hardcoded enumeration, deliberately, so a user's own
helpers in those directories survive. A wholesale writer paired with an
enumerated remover cannot stay in sync by construction: any file added to either
directory ships to every user and is then orphaned in their repo forever, since
it survives uninstall, leaves the directory non-empty, and the rmdir that follows
fails. Nothing reported this. 31,225 tests were green over it.

That is the same divergence class this epic exists to delete, sitting in the
installer, so it gets the same remedy CLAUDE.md prescribes for it: a parity
assertion that fails the moment the two surfaces disagree. The test compares each
directory's real contents against its enumeration and names the offending file
plus the constant to add it to.

Both enumerations are hoisted to module scope and exported, so the test asserts
on the actual arrays rather than pattern-matching the installer's source — no
allow-test-rule annotation needed. Proven non-vacuous both ways: empty diff on
the current tree, correct report when an unenumerated file is injected.

scripts/changeset/ turned out to carry the identical defect and is covered too.

cbd180c5cd test(#3147): bound the lint/changeset/docs cluster onto the process seam (#3181)
* test(#3147): bound the lint/changeset/docs cluster onto the process seam

Migrates 69 unbounded sync spawn sites across 24 files. Allowlist 73 to 49.

Two shared helpers move: tests/helpers/graphify.cjs (6 importing suites) and
tests/fixtures/index.cjs, whose three quoted-argument shell strings became
single argv elements rather than whitespace splits.

changeset-lint's throw-native git() helper routes to gitOrThrow; migrating it
to bare runGit would have silently swallowed a failure that is loud today.
ingest-docs goes the other way -- its catch never rethrew, it degraded failure
into data every call site asserts on, so throwIfFailed would have thrown where
the original returned. The design doc said otherwise and was corrected.

tsconfig-noemit runs a real tsc --noEmit and takes a bespoke 180000ms per the
ensure-runtime-build precedent, not the 30000ms build-hooks norm -- that norm
is for a file copy, and sizing against a label rather than the work is the
same error in the opposite direction.

* test(#3147): add toLegacyResult and settle review findings

The seam exposed a throwing adapter (throwIfFailed) but no non-throwing one,
so eight files independently re-derived the same unwrap back to the legacy
{status, stdout, stderr} shape. That is the third time this epic produced N
copies of one mechanism -- seven throw wrappers in Wave 1, fifty-two timeout
constants in Wave 2, eight result adapters here. The pattern is that whenever
the seam does not expose a mechanism, every suite re-derives it.

toLegacyResult now sits beside throwIfFailed, with its own tests.

Two sites are deliberately NOT converted: changeset-cli's runRender and
runRenderIn return {status, report, stderr} from parsed JSON and never a raw
stdout, so they are a different shape family. lint-legacy-dir-name keeps its
local GUARD_TIMEOUT_MS: 30000 matches the build norm numerically but bounds a
lint probe, not hooks bundling, and importing it would encode a coincidence
as a relationship.

27aa40f65e fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ directory (#3175)
* test(#3023): failing-first guard — pi must not stage hooks in its reserved dir

pi reserves <configDir>/hooks as its deprecated extension location and warns
on every startup when it exists. Assert a pi install stages the shared hook
bundle under gsd-hooks/ instead, manifests it there, and never creates hooks/.

Also adds pi to the local-scope dir table in install-shared.cjs: pi was in
RUNTIME_META but not LOCAL_DIR_NAME, so scope:'local' resolved
path.join(root, undefined) and no local pi install could be exercised.

Fails before the fix. Verified via the remote runner.

* fix(#3023): stage pi's shared hook bundle outside pi's reserved hooks/ dir

pi reserves <configDir>/hooks as its now-deprecated extension location and
warns on every startup when that directory merely exists — checkDeprecatedExtensionDirs()
guards the warning with a bare existsSync(), unlike its tools/ sibling. GSD staged
its shared hook bundle exactly there, and pi's advised remediation (move it to
extensions/) would break the adapter's paths and expose GSD's .js helpers to pi's
extension auto-discovery.

The bundle directory name is now runtime-descriptor-driven: hostBehaviors
.sharedHooksDirName, defaulting to 'hooks' so all 18 other runtimes are
byte-identical. pi sets 'gsd-hooks'. The name is validated as a single path
segment — separators, dot-only segments, trailing dots, absolute paths, NUL,
and Windows reserved device names all fall back to the default, because the
value is joined onto a user's config root and written to.

Renamed in place rather than relocated: hook scripts resolve siblings via
__dirname/.., so a depth change would silently break them.

- install / uninstall / manifest sites all read the resolved name
- pi/gsd.cjs probes gsd-hooks then hooks, so dev checkouts and half-upgraded
  trees still resolve; the never-throws contract is preserved
- new migration 009 retires the legacy pi hooks/ dir on upgrade, using a new
  non-recursive remove-empty-dir engine primitive (rmdirSync only,
  symlink-refusing, containment-guarded); ADR-0008 amended accordingly
- fixes two latent name-dependencies the rename exposed: the stale-hook scan
  and the injection scanner's self-exclusion both hardcoded 'hooks'

Verified on the remote runner.

Closes #3023

* fix(#3023): close review findings and align emitted provenance with the rename

Adversarial review found two defects, and the remote runner found four
failure clusters. All fixed here.

Review BLOCKER — detect-custom-files was blind to the renamed bundle.
GSD_PREFIX_MANAGED_DIRS in gsd-tools.cjs hardcoded 'hooks', so for pi the
whole gsd-hooks/ tree was invisible to the custom-file scan and user-added
files there were never backed up before the next update's clean-install wipe.
The dir set now resolves via the .gsd-runtime marker plus the shipped
capability registry (never bin/install.js, which is not shipped into installed
trees), and falls back to scanning every known candidate when the runtime
cannot be determined — over-scanning is safe, under-scanning is the data loss.

Review MAJOR — the pi adapter bound to an empty bundle. resolveSharedHooksDir
accepted any directory, so an interrupted install left gsd-hooks/ winning over
a fully-staged legacy hooks/ and every hook silently no-opped. A candidate now
qualifies only if it is non-empty.

Remote-runner clusters:
- emitted-provenance had no rule for the gsd-hooks/ family; added two pi-scoped
  rules pointing at the same sources the existing hooks/ rules use. The table is
  total, so an unattributed family is a hard failure by design.
- pi tests in install-minimal-hooks and the install integration suite asserted
  the old layout; updated to derive the dir name from the descriptor rather than
  hardcoding either name.
- 19 unrelated-looking failures on node22 only were a leaked fs mock: t.after()
  runs in registration order, cleanup was registered before mock.restoreAll(),
  and node22's JS rimraf calls the public fs.rmdirSync while node24's native
  path does not — so the EACCES stub leaked process-wide on one lane. Restore
  now runs first.

Verified on the remote runner.

* fix(#3023): honor PI_CODING_AGENT_DIR, ack the rename ripple, fix expandTilde

pi resolves its agent dir as PI_CODING_AGENT_DIR ?? ~/<CONFIG_DIR_NAME>/agent
(packages/coding-agent/src/config.ts). GSD's pi descriptor declared an empty
configHome.env, so a user with that variable set had GSD installed where pi
never looks. Added the env name; the dot-home-nested resolver already handled
the override, so no resolver logic changed.

Also fixes expandTilde in the shared runtime-homes resolver, found while adding
that: it hardcoded os.homedir() and ignored the opts.home every caller threads,
so EVERY runtime's tilde-valued env override (claude, antigravity, windsurf, pi)
silently resolved against the real home. That is a correctness bug and a
test-escape hazard — a sandboxed test asserting on a tilde override reached the
developer's actual home directory. Now threaded through every branch; behavior
with no injected home is unchanged.

Adds the emitted-drift ack fragment for the 58 pi paths whose emitted location
moved with the rename. The provenance rules satisfy the totality gate; the
differential gate needs the ack because the hook sources are byte-unchanged —
only the installer's target directory moved. The two hook files this branch
genuinely edits stay attributed and are not double-acked.

Note on piConfig.configDir: it is read from pi's OWN installed package.json
(getPackageDir walks up from pi's __dirname), alongside piConfig.name — a
white-label setting for a redistributed pi fork, not a per-project user setting.
Documented accordingly rather than treated as an unsupported override.

Verified on the remote runner.

* fix(#3023): reject blank env overrides, pin adapter/descriptor parity

Three review findings, all fixed.

A whitespace-only config-dir override was accepted verbatim: the guard was
`if (val)`, falsy only for the empty string, so PI_CODING_AGENT_DIR='   '
resolved to a literal three-space directory name instead of falling back to the
descriptor default. Fixed across every env-consuming branch — dot-home,
dot-home-nested, all three xdg steps, and generic-agents-root — not just pi's.
Non-blank values are still never trimmed, so '~/My Agent Dir' keeps working.

pi/gsd.cjs's probe list and the descriptor were two independent sources of truth
for the bundle directory name; a future rename would have desynced them silently
and left every pi hook quiet with no error. The probe list stays deliberate — it
must resolve in a dev checkout and a half-upgraded tree, where the registry's
answer would be wrong — so this adds the parity assertion the repo's
generative-fix-divergence rule calls for: the descriptor value must be the FIRST
candidate, and the default must remain present.

Changeset body rewritten to cover the two later user-facing fixes it had not
caught up with.

Verified on the remote runner.

* chore(#3023): backfill changeset PR number

* fix(#3023): anchor injection-scan patterns and fix a macOS detection hole

CI's security job flagged CONTEXT.md:124 — pre-existing prose reading 'not the
same fact as a genuinely empty or absent one'. The match was the 'act as a'
INSIDE 'f-act as a': the pattern had no left word boundary, so any word ending
in act tripped it (fact, impact, contract, artifact, interact, redact,
abstract). My four-line CONTEXT.md edit dragged the latent false positive into
this PR because the scan is diff-scoped by file but reads whole files. Anchored
with (^|[^[:alnum:]]) rather than rewording maintainer-owned prose, which would
have left the class alive for the next PR touching any file saying 'fact as a'.

Auditing the rest of the list for the same class surfaced a real detection hole:
the eval/exec/Function patterns matched a quote via \x27, a GNU-grep-only hex
escape. BSD/macOS grep reads it as four literal characters, so single-quoted
eval('...')/exec('...') payloads were NEVER detected there while passing on
GNU-grep CI. Replaced with a literal apostrophe class.

Boundaries were added only where a real word-suffix collision exists; exec,
jailbreak, developer mode and the role-manipulation family were audited and
deliberately left unanchored. 22 new cases cover both directions — the false
positives now scan clean, and every real payload still fires, including the
quote/punctuation/start-of-line boundary forms.

Also builds this branch's injection test fixture at runtime instead of carrying
the literal phrase, so the payload keeps its teeth without tripping the scan.

Verified on the remote runner.

8f75e27554 fix(#3045): fail closed when an executor dispatch drops its resolved isolation (#3069)
* feat(#3045): deny an executor dispatch that drops its isolation flag

Every isolation gate already resolved correctly. The resolved value then reached
the executor through a prose instruction telling the model to substitute it into
a call the model composes itself, and nothing verified the substitution. When it
was dropped, the executor edited and committed in the user's primary checkout
with no consent and no warning.

A prose backstop would be the same class of artifact as the defect, so this is a
shipped PreToolUse hook on the Agent tool. It fires at the instant of the call
rather than being read once at the top of a workflow, which is the only placement
the model cannot skip.

The guard is inert unless it can positively establish that this is a GSD project,
that the project resolves to harness isolation, and that the dispatch targets an
executor. A non-GSD repo has no invariant to enforce. Where it cannot read the
configuration at all, it denies rather than assuming, with its own reason -- a
guard that cannot verify must not answer safe. A malformed payload allows rather
than throwing.

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

* feat(#3045): extend the isolation guard to Cursor

Cursor is the second of only two runtimes that resolve harness isolation, so
shipping the guard for Claude alone left half the exposed surface unguarded while
the changeset implied it was covered.

The two runtimes fail differently. On Claude the harness flag is a per-dispatch
kwarg the model must copy into a call it composes, and the defect is that it can
be dropped. On Cursor the flag is --worktree, which applies to the whole session,
and the subagent-start payload carries no isolation field at all. There is no
flag to check, so the guard verifies the effective state instead: whether the
workspace is genuinely running outside the user's primary checkout. That is a
stronger check than the Claude one because it tests reality rather than intent,
and it is commented so nobody later rewrites it into a flag check.

Isolation is established two ways, either sufficient: the workspace resolves to a
linked git worktree, or it sits under the worktree root Cursor manages. The
second matters because a directory Cursor placed there is a legitimate isolated
session even before it becomes a distinct git worktree, where linkage alone would
report no repository.

Detecting linkage required a new primitive rather than the existing context
resolver. That resolver short-circuits on finding a local .planning directory
before it ever compares the git directory to the common one -- and an isolation
worktree normally has its own checked-out .planning. Reusing it would have read a
correctly isolated session as unisolated and denied it, which is the failure
direction that gets a guard switched off. The comparison is now its own
shortcut-free function that the resolver delegates to after its own shortcut, so
existing behavior is unchanged, and the case that would have broken is pinned.

The subagent type is checked before any configuration is read, so an unreadable
config cannot deny a dispatch this guard would never have enforced against.

The input-schema comment on the Cursor hook documented only the fields common to
every event and omitted the ones specific to this one. That omission cost a
halt during this work; it now documents both.

* fix(#3045): enforce the resolved dispatch decision, not the host capability

The guard keyed on the registry's dispatch.isolation, which says only that a
runtime is CAPABLE of harness worktrees. The decision that actually governs a
dispatch is the one the workflow resolves after gating, and that legitimately
comes out as sequential in three documented cases: a project setting
use_worktrees false, a per-plan submodule intersection, and the base-check
auto-degrade. The workflow tells the model to omit the flag in exactly those
cases, and the guard was denying every one of them.

The third case matters most. The preceding fix made the base-check degrade on
git timeouts and a missing git binary, where it had previously answered "safe".
That correction is right, and it means a transient hang now degrades to
sequential far more often than before -- so the two changes composed into a trap
where the workflow behaved exactly as designed and the guard blocked it.

The workflow already resolves isolation in shell, deterministically, which is
what makes it a trustworthy source in a way the model-authored call is not. It
now records that resolved value through a dedicated verb, and both guards read
it first. A fresh record is authoritative, so sequential dispatches pass
untouched. Absent or stale, the guards fall back to the capability check
combined with the project's use_worktrees setting, which still covers the case
that never reaches the workflow.

Also widened the matcher to accept Task alongside Agent, since a host that names
the tool Task would otherwise leave the guard silently inert while implying
coverage; stopped assuming Claude when no runtime is declared, which is the
shipped default and would have demanded a Claude-only argument elsewhere; and
made a non-git project inert rather than denied, since advising a worktree
session is not actionable without a repository.

The original diagnosis never modeled sequential mode as legitimate. That
omission is what let this through, and it is now recorded there.

* fix(#3045): record at resolution and bind the record to its dispatch

Two independent reviews converged on the same failure: the guard was fail-open in
a default install, so it did not catch the defect it exists to catch. A shipped
project carries no runtime key, which made "runtime not confidently known" the
common case rather than a corner one. A record asserting that isolation was
required but carrying no flag then fell through to a capability lookup that
answered "none", and the dispatch was allowed. The flag itself only arrived from
a second shell block -- the same block a model dropping the argument would also
skip. A test had pinned that behavior as intended.

The record is now written by the resolver, as an unavoidable consequence of
asking for the value, rather than by a step the model is told in prose to go and
run. A guard against a prose-carried value cannot itself depend on prose. Mode,
flag and identifiers are written together and atomically, so the flagless window
is gone, and a record asserting isolation with no resolvable flag now denies
instead of degrading. Runtime is also resolved from the installer's own recorded
default, which makes confident resolution the normal case.

The per-plan submodule gate degrades after the phase-level decision and never
re-recorded, so a plan that legitimately ran sequentially was denied against a
still-fresh phase record. It now records its own, scoped to the plan.

A record also authorized any dispatch for four hours. One phase degrading to
sequential could silently license an unisolated dispatch in the next. Records
now carry phase and plan, the guards require them to match, and the window is
minutes rather than hours -- the resolver rewrites it before every dispatch, so
a long window bought nothing and only widened the hole.

The flag validator rejected any value beginning with two dashes, which is exactly
the form Cursor and Windsurf declare, so their real value could never have been
stored. Writer and reader also derived the record path differently and diverged
inside a linked worktree without local planning state.

The predictable path remains a way to silence the control without leaving a trace
in the diff. It grants no access an agent with shell does not already have, so it
is documented as accepted rather than redesigned around.

* fix(#3045): correct the staleness boundary and unmask a vacuous parity test

The remote runner returned twenty failures. One was a real production defect the
boundary case existed to catch: a record whose age exactly equalled the staleness
window was treated as fresh, so it stayed authoritative for one tick past its own
expiry. Freshness is now strictly inside the window.

The parity test meant to stop the two guards' executor lists from drifting could
never have failed. Its project fixture was a bare directory rather than a
repository, so the non-git inert branch answered before the executor list was
ever consulted. It asserted agreement it never actually measured. The fixture is
now a real repository, like every sibling in the file.

A test also asserted that Windsurf declares the worktree flag. It does not --
Windsurf resolves to no isolation by design, having no named concurrent dispatch
to isolate. The test claimed a registry fact that was never true, and a comment
in the resolver repeated it. Both corrected, and the test now proves what it
should have all along: that the parser accepts any bare flag value, rather than
one runtime's supposed value.

The new guard was missing from the bundled-hook whitelist, which is the surface
that decides what actually ships, and the per-plan gate had gained calls to the
launcher without the preamble those calls require. The changeset carried
parenthetical product descriptions the purity rule forbids.

* test(#3045): make the guard tests hold on Windows

Two tests redirect HOME to control where the installer-persisted runtime default
is read from. Node resolves the home directory from USERPROFILE on Windows and
never consults HOME, so both silently read the real runner profile, found no
recorded runtime, and asserted against a project the hook had not recognised. The
production code was already correct in asking the platform rather than the
variable; only the tests were wrong to assume one variable answers everywhere.
The helpers now mirror the override onto both.

The symlink spoofing test also created a directory symlink unconditionally, which
needs elevated privileges on Windows. It survived on this runner, but it would
fail on any host without them, so the creation is now attempted and the test
skips explicitly when it cannot be done -- a bare return would have counted as a
pass and hidden the gap.

Skipping alone would have left the platform uncovered, so the behaviour it proves
is now also driven in-process through an injected realpath, following the seam
already used for the clock. That case no longer depends on privileges at all, and
the end-to-end test keeps its original assertions wherever symlinks work.

ed360cd99f chore(#2995): extend fragment emission to agents/ and reclaim size-cap headroom (#3058)
* feat(#2995): extend fragment emission to agents/ across every read point

Epic #1671 Phase 6.4. `composeWorkflow` stripped `<!-- gsd:section -->` markers
only for `gsd-core/workflows/`, so a marked agent shipped its markers verbatim
into every runtime — and agent text is loaded into a subagent's context on every
dispatch.

The issue proposed widening the `copyWithPathReplacement` guard. That is a no-op
for agents: agents never traverse that function. Agent content is read for
emission at five independent points, and the obvious chokepoint
`stageAgentsForProfile` short-circuits on the DEFAULT `full` profile
(`skills === '*'` returns the real unstaged directory), so a hook placed there is
dead code on most installs.

Composition now happens at two call sites instead of five parallel surfaces:
`stageAgentsForRuntimeWithConverter` (with `agentsKind` and `kimiAgentsKind`
routed through it via an identity converter) and the inline agent loop in
bin/install.js. Both compose BEFORE any path rewrite, so a `.claude/` ->
`.windsurf/` regex can never reach inside a marker attribute — the ordering
#2930 established for workflows.

`installCodexConfig` was the fifth read point: Codex embeds each agent's prompt
into a per-agent `.toml` via its own readFileSync. Call-graph analysis missed it;
the exhaustive per-runtime emission sweep found it. That is why the new guard is
behavioral rather than structural — a sixth read point fails the sweep without
anyone remembering to extend a list.

tests/agent-fragments-emission.install.test.cjs spawns a real installer for every
runtime at every agent-bearing scope, derived from RUNTIME_META and the
capability registry at run time so a new runtime cannot be silently
under-covered. It asserts markers are absent AND the `when="always"` body is
retained, so marker-absence cannot be satisfied by dropping content. An
identity-composer negative control proves the assertion can fail.

Verified: 0 install failures, 0 marker leaks, body retained on 27 runtime/scope
paths; red before the wiring on claude(global+local), zcode(global+local),
kimi, codex and opencode.

Refs #2995

* chore(#2995): give the tightest agents headroom and correct the design lock

Epic #1671 Phase 6.4, second half.

`agents/gsd-verifier.md` had 12 bytes of headroom under its 49,152-byte LARGE
cap and `agents/gsd-debugger.md` had 147 under its 57,344-byte XL cap. Both now
extract reference material to `gsd-core/references/` behind an @-reference — the
documented DEFECT.AGENT-FILE-SIZE-CAP-BREACH remedy:

  gsd-verifier  49,140 -> 46,371 B   headroom    12 -> 2,781
  gsd-debugger  57,197 -> 48,851 B   headroom   147 -> 8,493

Byte accounting proves no content was lost: the combined agent+reference delta
is exactly the new files' headers plus the agents' slim replacement blocks. Each
agent keeps its routing table and a one-line summary per entry, so it degrades
gracefully on a runtime that does not inline @-references.

`agents/gsd-planner.md` is untouched and still passes both char guards
(49,130 < 49,152); it needed no change, so it took none.

The other nine LARGE/XL agents carry NO gsd:section markers, and that is
deliberate, not deferred. `when=` selection is read from
gsd-core/workflows/section-manifest.json, which gen-section-manifest.cjs derives
from gsd-core/workflows/*.md only — shape `{workflows: ...}`, no per-agent key,
no per-agent init entry point. An agent atom therefore fails admission gate (2)
("a fact the init seam demonstrably computes at a real entry point") and would
evaluate false forever while looking like working gating. Marking agents would
manufacture exactly the silent-inertness rot the frozen vocabulary exists to
prevent.

ADR-1671 gains three amendments, two of which close gaps /adr-phase-coverage
found against what actually merged:

  - The 19 -> 29 vocabulary widening shipped in #2994 with no coordinated ADR
    amendment, which that bullet's own rule forbids. Recorded now.
  - `flag:--verify-only` was one of six atoms #2992 withheld and deferred to
    "the LARGE/XL rollout phase". Five shipped; this one is permanently
    rejected, and that disposition lived only in a merged PR body.
  - Phase 6.4's own finding: emission extends to agents/, gating does not.

CONTEXT.md's glossary was stale on both seams — Workflow Fragments Module still
listed the original 4-atom vocabulary and described when= as "not yet acted on",
and Section Manifest Module still described InvocationFacts as
{waveFlag, phaseNumber, hasPriorPhases}. Both now match the shipped contract.

Inventory manifest regenerated AFTER build:lib per the documented ordering
landmine; 19 install-tree fixtures pick up the two new references.

Refs #2995

* chore(#2995): correct the compose-site count and mark the raw stager

Self-review found two comment defects in the prior commit. The agentsKind
comment claimed composition lands at TWO call sites; it is three, since
installCodexConfig's per-agent .toml writer was added after that comment was
written. And stageAgentsForProfile is now production-dead — both callers route
through the composing stager — while staying exported and unit-tested, which
makes it a trap: it does a raw copyFileSync and short-circuits to the unstaged
source directory under the default profile, so a future caller would silently
reintroduce the marker-shipping path. Its JSDoc now says so.

* test(#2995): guard the marker-documenting-doc class for agents

Widening the composer's scope to agents/ makes reachable the exact class #2930
narrowed scope to avoid: a file that DOCUMENTS the marker syntax with an
unfenced example is indistinguishable from a real marker, so the composer drops
that line from the emitted artifact.

Three rows. A fenced example must compose byte-identically. No shipped agent may
carry a marker outside a fence — asserted by parsing every real agent and
requiring zero explicit sections, which is what makes the fence protection
load-bearing rather than decorative. And a non-vacuity row asserts an UNFENCED
marker IS parsed as a real marker, so if that ever stops being true the second
row is guarding nothing.

Also applies two review findings: stageAgentsForProfile's new JSDoc claimed it
had no production caller, which is false — bin/install.js's _stageAgents still
calls it, and its consumers compose before writing. Corrected to state the
invariant instead. And a let/const nit in the emission sweep.

* fix(#2995): keep verifier status vocabulary in the agent, fix a wrong fixture

The first remote run came back red with three failures. Both root causes were
mine.

1. tests/agent-frontmatter.test.cjs requires agents/gsd-verifier.md to literally
   contain HOLLOW and DISCONNECTED. The Step 4b extraction moved that status
   vocabulary into gsd-core/references/verifier-wiring-patterns.md, so the agent
   no longer had it.

   Byte accounting said no content was lost, and byte-wise that was true — but a
   contract required those tokens to live IN THE AGENT. That is ADR-1671:66's
   flexReserve floor stated concretely: a load-bearing fragment must not be
   trimmed out of its host, and "the bytes still exist somewhere" is not the
   test. The two status tables are restored to the agent and deliberately
   mirrored in the reference with a note saying so, so the procedure there still
   reads standalone. gsd-verifier lands at 47,069 B — headroom 12 -> 2,083,
   rather than the 2,781 the first attempt claimed.

2. Row 12b of the new marker-documentation guard asserted that an unfenced
   marker example parses as a real marker, and threw instead:
   "unmatched /gsd:section close marker". The grammar is WHOLE-LINE only. The
   fixture had put the OPEN marker inline mid-sentence, so it was correctly not
   recognised as an open while the close, on its own line, was.

   That is a real refinement of the hazard this guard exists for: only a marker
   on its OWN line is mis-parsed — which is exactly how a documentation example
   is normally written. Row 12b now uses a whole-line marker, and a new row 12c
   pins the inline case as explicitly NOT a marker.

No test was weakened to accommodate the change; the change was corrected to
satisfy the tests.

* chore(#2994): fragmentize progress.md forensic audit onto the fragment model

Extract the --forensic-gated forensic_audit step to
workflows/progress/steps/forensic-audit.md behind a section marker, and
repair progress.md's init line to forward --forensic so the atom is
actually true in production rather than only under direct CLI tests.

progress.md shrinks 32630 -> 27207 bytes.

* chore(#2994): fragmentize the four manifest-wired workflows

new-project, quick, new-milestone and progress each already had a
dedicated cmdInit* entry point but zero marked sections. Extract nine
gated bodies to workflows/<wf>/steps/ behind section markers and repair
each init line to forward its flags.

Fold --full into the discuss/research/validate facts inside cmdInitQuick
so the when= grammar never sees an OR, per the chunked-mode precedent.

Fixes found while working, per the no-defer rule:
- cmdInitProgress passed no phase info to buildSectionManifestField, so
  state:phase-mvp-mode was permanently false — an atom in the vocabulary
  whose fact could never be computed.
- the quick init router folded flag tokens into the free-text
  description, which the new forwarding would have corrupted.
- a #2508 dispatch note was nested inside quick.md's Agent(prompt=)
  fence, leaking orchestrator guidance into the subagent prompt.
- progress.md had a 3-vs-4 backtick outer-fence imbalance.

* chore(#2994): fragmentize verify-work.md and admit state:ui-phase-active

Wire cmdInitVerifyWork to buildSectionManifestField — it was a dedicated
entry point that never emitted a manifest — and mark two sections.

state:ui-phase-active folds (plan:pre hooks include an active ui step) OR
(the phase dir holds a *-UI-SPEC.md) into one boolean in init.cts, so the
grammar still sees a single operator-free atom. The inner Playwright-MCP
check stays as prose inside the fragment: it is live session state and no
init seam can precompute it.

The MVP false-branch note is a real fallback, not redundant prose, so it
sits outside the marker — gating it away would delete the text needed
precisely when MVP mode is off.

* test(#2994): follow moved workflow content in drift guards

Retarget every guard that asserted on content this branch moved into
workflows/<wf>/steps/, mirroring 815b3d897. Each retargeted assertion was
verified to still fail when its step file is blanked, so none was
weakened into vacuity.

Three assertions in verify-mvp-uat were genuinely red. Three more were
worse than red — passing for the wrong reason:
- quick-commit-boundary and worktree-cleanup anchored on indexOf('Step
  5.6'), which matched a later cross-reference and sliced 16069 chars
  that coincidentally held the asserted substrings. Replaced with an
  expandWorkflowSections helper that splices step content back in place.
- phase6-review-capabilities lost its end boundary and widened to EOF.
- playwright-ui-verify matched 'UI' in an unrelated bullet and 'fall
  back' in a subagent-dispatch line after the real content moved.

* chore(#2994): fragmentize code-review and complete-milestone, admit three atoms

Add dedicated cmdInitCodeReview and cmdInitCompleteMilestone entry points

processes) and stay byte-identical for their other callers.

Admit flag:--fix, state:fallow-enabled and state:git-create-tag, each with
a consuming section and a fact its own entry point computes.

Both sections had the resolver-in-body hazard: the fallow config-gate and
the git.create_tag check each sat inside the very block being gated, so
gating would have disabled the resolver that decides the gate. Both are
hoisted into init and the bodies now consume the resolved fact.

Also fixes two genuinely red tests found while working, per the no-defer
rule:
- workflow-fragments' frozen-vocabulary lock was missing
  state:ui-phase-active, so commit 7ef7f8336 shipped red. Lint and build
  both passed over it, which is why neither is sufficient verification.
- code-review's quick.md capability-hook assertion carried a stale
  delimiter after the 18ff35d20 extraction.

* chore(#2994): fragmentize autonomous.md and admit state:plan-strategy-converge

Five sections share one atom, the pattern plan-phase already uses for
flag:--research-phase. The atom folds --converge OR --cross-ai into a
single boolean in cmdInitAutonomous so the grammar stays operator-free.

cmdInitAutonomous is additive; init.milestone-op, init.manager and
init.phase-op are untouched and still consumed. The $PLAN_STRATEGY bash
resolver is deliberately retained — ungated local-planning bullets still
read it, so the init-side fact supplements it rather than replacing it.

converge-fail-fast required splitting one bash fence so the always-run
CONVERGENCE_ARGS construction stays outside the marker. All three
flag-absent fallbacks were left outside their markers.

* chore(#2994): fragmentize review and discuss-phase-assumptions

Admit state:reviewer-instances-configured (two peripheral notes share it;
the core reviewer-lane dispatch stays unmarked — it is the workflow's
primary always-evaluated logic, not an optional branch) and
state:auto-advance-active, which folds --auto OR two config keys into one
boolean so the grammar stays operator-free.

discuss-phase-assumptions was the highest-risk edit in this PR. Its
auto_advance step is a full if/elif/else; gating it whole would have
deleted the flag-absent fallback needed exactly when --auto is off. Split
verified exact: resolvers 636-651 and the 'End here' fallback 668-669 both
stay outside the marker; only 653-667 is gated.

Adds emitted-drift acks for the two files that grew — review.md (+55 B)
and autonomous.md (+737 B from 80799211c, which had none and would have
red-gated the push.

* chore(#2994): fragmentize docs-update, update, transition and new-milestone Part A

Completes the 13-workflow rollout. Three of these had no init call at all
and gained a dedicated entry point plus their first gsd_run query line.

Admits state:is-monorepo and adds state:next-channel, state:workstream-active
and state:flat-mode. Vocabulary 26 -> 30 atoms.

Part A of new-milestone applies when NO workstream is active — the negation
of state:workstream-active. Rather than teach the grammar negation, which is
the Greenspun drift the frozen list exists to prevent, it gets a separate
positively-phrased atom whose fact is the inverse. Part B, which always runs,
stays outside the marker.

flag:--verify-only is deliberately NOT admitted: docs-update has no
contiguous purely-additive region for it, and an atom without a consuming
section is dead vocabulary. Evidence recorded in the slice report.

update.md reuses its existing resolved $GSD_TOOLS rather than prepending the
canonical preamble, which would have clobbered it.

* fix(#2994): stop automated-ui-verification re-resolving its own gate, retire dead vocabulary

Two defects the new tests caught.

The automated-ui-verification step re-ran gsd_run loop render-hooks and
recomputed UI_PHASE_ACTIVE inside a body that is only read when that fact
is already true — the circular self-disabling pattern this design forbids,
introduced by 3c654b168. cmdInitVerifyWork now exposes ui_phase_active and
the step consumes it. Its launcher preamble goes too: no gsd_run remains.
The Playwright-MCP check stays as prose — that is live session state.

Dead vocabulary predating this PR: flag:--full and state:needs-codebase-map
were admitted with a gate-1 claim that never materialized. flag:--full is
removed, redundant once quick folds it into discuss/research/validate.
state:needs-codebase-map gets the real consumer it always lacked, gating
new-project's codebase-map offer. Vocabulary 30 -> 29, and no atom is now
without a consuming section.

* test(#2994): add the atom-admission, inversion and resolver-hoist gates

The two existing parity guards prove vocabulary/predicate symmetry but
never that a fact is computed — an atom no cmdInit* assembles evaluates
false forever. These close that hole:

- per-atom satisfiability for all 29 atoms, plus an anti-vacuity assertion
  so the loop cannot silently cover zero atoms
- dead-vocabulary check against the shipped manifest
- inversion guard: the flag-absent fallbacks in discuss-phase-assumptions
  and verify-work must stay outside their markers
- data-driven resolver-hoist guard over the shipped manifest, so a future
  extraction cannot reintroduce the circular class
- compound-fold coverage (--full, --cross-ai, --rc, config-only --auto)
- null-vs-[] degraded/computed distinction, and flag value shapes

Also repairs the frozen-vocabulary lock, which was stale and red for the
seven atoms earlier commits on this branch shipped.

* fix(#2994): dedupe the phase-fallback block and harden --ws parsing

Review findings.

MAJOR: the three new init entry points each pasted a verbatim copy of the
guardedFindPhase/guardedGetRoadmapPhase fallback, taking the repo from four
copies to seven — DEFECT.GENERATIVE-FIX. Extracted applyRoadmapFallback and
folded six of the seven; each call site keeps its own field-set via a
closure. Duplication removed rather than papered over with a parity test.
cmdInitPhaseOp stays out: its fallback omits has_reviews, so it is not a
byte-identical copy, and it is CRITICAL-radius.

LOW, pre-existing: GSD_WS captured [^[:space:]]+ and expands unquoted, so a
workstream name holding glob metacharacters would expand against the
filesystem. Narrowed to [A-Za-z0-9._-]+. The unquoted expansion is kept —
it must word-split into two args and vanish when empty.

Also restores the vocabulary ordering convention, and fixes a masked test
bug the mandated run surfaced: the flag-forwarding guard checked only the
first init line per workflow, but new-milestone has two, so a real failure
was reporting exit 0.

* fix(#2994): resolve the 15 failures from the full matrix run

All 15 were real and identical on both lanes.

REAL REGRESSION: autonomous.md hit 41479 chars against the #2196 guard's
40960 cap — a CHARS cap distinct from the LARGE tier byte cap, which the
five section stubs pushed it over. Extracted the 3a.5 UI Design Contract
body to references/; now 39968 chars, and the file nets -795 B vs base, so
its growth ack is deleted rather than left stale.

REAL DEFECT: docs referenced /gsd-transition, which is not a live
registered command. Reworded.

STALE FIXTURE: the emission byte-identity test hardcoded two marked
workflows; this branch legitimately marks fifteen. Fixture corrected — the
source was right.

The rest were drift guards over the eight workflows the earlier sweep did
not cover, retargeted at where the content now lives with non-vacuity
proven by blanking each step file and confirming failure. The GSD_WS
forwarding guard was checked as a possible real break and is not one: the
charclass narrowing is intact and forwarding works end to end.

* fix(#2994): retarget the UI-contract guards and clear two transitive advisories

The §3a.5 extraction that brought autonomous.md under the #2196 char cap
moved its body to references/autonomous-ui-design-contract.md, so ten
guards in autonomous-ui-steps and check-ui-safety-gate were asserting it
against the host. Retargeted via a combined read, each proven non-vacuous
by blanking the reference file and confirming failure.

This class had already bitten twice on this branch because each sweep was
scoped to the workflows touched at that moment, so this one was
exhaustive: ~70 test files across all 13 workflows, zero further broken or
vacuous assertions found.

Also clears two high transitive advisories the matrix flagged on one lane
— fast-uri GHSA-7p8r-x3mc-p8w7 and three ip-address SSRF/trust-boundary
issues. Both pre-date this branch: package-lock.json was untouched until
now, so the production tree was byte-identical to the base. Lockfile-only,
package.json unchanged, verified against a real npm ci install.

c6ce4d1d9a fix(#2755): resolve the kimi hooks-TOML root per runtime (#3032)
* test(#2755): failing-first coverage for per-runtime kimi hooks root

Install/uninstall filesystem-shape rows over a sandbox HOME (no permission
tricks) plus resolver unit rows. Covers both uninstall directions, which is
where a fix applied only to the install call site would drift.

* fix(#2755): resolve the kimi hooks-TOML root per runtime

resolveKimiHooksTomlDir took no runtime argument and hardcoded ~/.kimi, but
both kimi and kimi-code route through the single hooksSurface=kimi-hooks-toml
branch. A --kimi-code install therefore wrote its [[hooks]] block, hook bundle
and CommonJS marker into Kimi CLI's config file, and a --kimi-code uninstall
stripped Kimi CLI's block.

Adds a runtime selector to the resolver -- kimi keeps ~/.kimi + KIMI_SHARE_DIR,
kimi-code gets ~/.kimi-code + KIMI_CODE_HOME, per Kimi Code's own upstream
data-locations and hooks docs -- and passes the runtime at both the install and
uninstall call sites. An omitted or unrecognized runtime still resolves ~/.kimi,
so the exported no-arg contract is unchanged.

* test(#2755): use centralized helpers and add a divergence guard

Review findings, all fixed in-PR:

- The new test block reimplemented runMinimalInstall, createTempDir and
  toPosixPath. Extends runMinimalInstall with optional root/extraEnv instead
  (back-compat: every existing caller passes neither) and uses the centralized
  helpers, per CONTRIBUTING's Use Centralized Test Helpers rule.

- Adds a parity assertion between the capability registry and the resolver: a
  third runtime declaring hooksSurface kimi-hooks-toml would silently inherit
  ~/.kimi, re-creating this very defect. The guard fires the moment those two
  surfaces drift.

- Adds an installer-level test proving KIMI_SHARE_DIR and KIMI_CODE_HOME do not
  interfere when both are set, which only the resolver unit covered before.

* test(#2755): track the kimi-code hooks root in the emitted-artifact gates

The remote runner caught a real ripple: moving kimi-code hooks to ~/.kimi-code
made 31 emitted paths unattributable and 58 emitted hashes unexplained, because
three parallel surfaces keyed on the literal .kimi path.

- HOOK_CONFIG_RELATIVE_PATHS excluded only .kimi/config.toml, so kimi-code's
  config.toml became manifest-visible; it embeds a platform-varying node-runner
  command and must stay out for both products.
- HOOKS_ROOTS, the package.json-marker branch and the synthesized-install-metadata
  pattern each named .kimi only.
- tests/fixtures/install-tree/kimi-code.json still recorded the old paths;
  regenerated via gen:install-tree.

Adds the per-PR drift acknowledgment for the 58 paths whose bytes are unchanged
but whose destination moved - a ripple no source diff can show, since no hook
script was edited.

* fix(#2755): clear production-tree security advisories

The remote runner's npm-integrity gate reported 2 high advisories in the
production dependency tree. My diff touches neither package.json nor
package-lock.json, so these come from the base -- but a red gate is not
something to wave off as pre-existing, so it is fixed here rather than deferred.

Lockfile-only, semver-in-range, via npm audit fix:
  fast-uri   3.1.4  -> 3.1.5   (host confusion via backslash authority introducer)
  ip-address 10.2.0 -> 10.4.0  (three SSRF / trust-boundary bypasses)
  hono       4.12.31 -> 4.13.0 (moderate; reverting it traded a high for a
                                moderate, so the full remedy is taken)

npm audit now reports 0 vulnerabilities at every severity, npm ci installs
clean from the updated lockfile, and the build and the kimi behavior both
re-verified afterwards.

067a4d1c6c fix(#2650): bound and auto-recover plan-phase planner/plan-checker stalls (#3015)
* test(#2650): add failing-first regression for plan-phase stall detection

Regression test for gsd_stall_should_recover / gsd_stall_watch and the
planner.stall_* config keys, none of which exist yet — proves RED before
the fix lands in the next commit.

* fix(#2650): bound and auto-recover plan-phase planner/plan-checker stalls

Mirrors the already-shipped executor.stall_* pattern (execute-phase.md, bug
#3212) but with a dispatch change the executor's prose-only surveillance
lacks: the standard planner spawn, chunked-outline planner spawn,
chunked-per-plan planner spawn, plan-checker spawn, and revision-loop
planner respawn now dispatch with run_in_background=true and are followed
by a real, bounded bash poll (gsd_stall_watch) that returns control to the
orchestrator on its own schedule instead of waiting indefinitely on a
subagent that may never return. On stall, the existing accept-plans/retry/
stop recovery menu (9a/11a) is auto-surfaced instead of requiring a manual
interrupt.

New config keys planner.stall_detect_interval_minutes (default 5) /
planner.stall_threshold_minutes (default 10) mirror executor.stall_*.

The helper functions (gsd_stall_should_recover, gsd_stall_watch) live in a
new lazily-loaded gsd-core/workflows/plan-phase/steps/stall-detection-
helpers.md rather than inline, and per-site prose is kept minimal, because
plan-phase.md is frozen under the ADR-857 Phase 6 PRE_PHASE6 gate
(tests/phase6-capstone-conformance.test.cjs) with ~36 bytes of headroom at
baseline; the net effect is plan-phase.md.md ships slightly SMALLER than
before (the old unconditional-wait ORCHESTRATOR RULE sentences are gone at
the five touched sites, superseded by the bounded watcher).

Also fixes a stale doc comment in tests/workflow-size-budget.test.cjs that
still described the per-file workflow-size-baseline.json guard removed by
#2724 (ADR-2719 Phase 4) as if it were still the enforcement mechanism —
discovered while verifying this fix's own byte budget.

Researcher and pattern-mapper spawns are untouched (out of scope per the
issue's Agent Brief).

* fix(#2650): make gsd_stall_watch single-cycle; harden numeric config inputs

Two review findings addressed on top of the prior commit:

1. gsd_stall_watch previously looped internally for the full
   threshold+interval duration inside ONE Bash tool call (up to 15 min at
   defaults) — a single call blocking that long risks the host tool's own
   timeout killing it before it ever prints a result, silently defeating the
   fix. Redesigned to a single sleep-and-check cycle per call, taking an
   explicit dispatch_ts so the orchestrator prose can repeat the (short,
   default 5 min) call until it resolves; the outer threshold is now
   enforced by dispatch_ts accumulating across calls, not by one call's
   duration. Documented the resulting trade-off (up to one interval of
   added latency on the success path) in the changeset and reference doc.

2. PLANNER_STALL_INTERVAL_MINUTES/THRESHOLD_MINUTES are config-controlled
   values that flow into bash arithmetic ($(( ))). A review flagged this as
   command injection; empirically verified against both macOS bash 3.2.57
   and Docker bash:5 that this is NOT actually exploitable (bash hard-errors
   on a `$(cmd)`-shaped arithmetic operand rather than invoking it) — but an
   unvalidated malformed value WOULD abort the stall-watcher itself with
   that bash error, silently defeating the exact hang-recovery this issue
   ships. Added integer validation with safe-default fallback, both at the
   config-resolution point and defensively inside gsd_stall_should_recover.

Also adds the previously-missing integration coverage for gsd_stall_watch's
real execution (grep/find/date plumbing), not just the pure classifier.

* fix(#2650): correct AC2 self-test — helpers doc may name teams-status in prose

The AC2 regression test asserted the stall-detection-helpers.md step file
never contains the substring "teams-status" at all, but the file's own
prose explicitly documents its independence from that guard (containing
the word by design). Narrowed the assertion to what actually matters: no
second `query teams-status` call site and no gating on it, not a blanket
absence of the word.

* test(#2650): regenerate golden install-tree fixtures for the new step file

gsd-core/workflows/plan-phase/steps/stall-detection-helpers.md is an
emitted file (installed for every runtime), so adding it changes the
install tree even though it is invisible to docs/INVENTORY.md and
docs/INVENTORY-MANIFEST.json (both explicitly scope to non-recursive
gsd-core/workflows/*.md — verified against the execute-phase #2930 and
pre-existing plan-phase step-file precedent, which are equally absent from
both inventory artifacts). The golden install tree snapshots the sorted
list of emitted relative paths per runtime, so a file invisible to the
inventory is still visible here. Regenerated via `npm run gen:install-tree`
— one line added per runtime fixture (19 files), no other drift.

* fix(#2650): restore 7 ORCHESTRATOR RULE labels; sync runtime-launcher preamble

Two more consequences of extracting helper bodies out of plan-phase.md,
both caught by verification (0017e1a78, 9 unique failures):

1. tests/plan-phase-drift-guard.test.cjs (#913) requires at least 7
   "ORCHESTRATOR RULE — ALL RUNTIMES" labels in plan-phase.md itself, one
   per agent spawn site. Moving the full explanatory blocks to
   plan-phase/steps/stall-detection-helpers.md carried 5 of the 7 labels
   out with them (only the untouched researcher/pattern-mapper sites kept
   theirs). Restored a short label at each of the 5 stall-watch sites,
   trimmed a few more redundant words ("Per 7.99, " — already established
   by the adjacent step-7.99 pointer) to stay under the frozen
   PRE_PHASE6 cap (94497 bytes, 21 bytes headroom).

2. tests/runtime-launcher-parity.test.cjs (#373) requires exactly one
   canonical gsd_run preamble, byte-equal to
   gsd-core/workflows/_runtime-launcher.snippet.sh, before the first
   gsd_run call in any workflow .md that calls it (recursive scan under
   gsd-core/workflows/, unlike the non-recursive inventory/step-tag-balance
   checks). The new step file's config-get calls use gsd_run without one.
   Fixed via `node scripts/sync-runtime-launcher.cjs`, verified: exactly 1
   preamble occurrence, before the first call, including the .claude/ and
   .codex/ home fallback arms.

Also verified (no fix needed, evidence recorded): the generic
`gsd-core-verbatim` identity rule in tests/helpers/emitted-provenance.cjs
(roots: ['gsd-core'], pattern matching workflows/.+) self-attributes any
new gsd-core/workflows/** path to itself, so the new step file needs no
drift-ack entry — consistent with plan-phase.md's own net shrinkage
requiring none either.

* test(#2650): acknowledge plan-phase.md's +14 byte drift

Restoring the 5 ORCHESTRATOR RULE — ALL RUNTIMES labels (#913) flipped
plan-phase.md from -142 bytes (post-extraction) to +14 bytes net growth
against baseline (94483 -> 94497), which the differential attribution
size ratchet (tests/emitted-attribution.test.cjs) correctly flags as
unacknowledged growth. Added tests/emitted-drift-acks/2650-plan-phase-
stall-detection.json, keyed on the bare filename plan-phase.md per the
existing fragment schema (see tests/emitted-drift-acks/2649-diagnose-
execute-plan-base-check.json), explaining the growth as exactly the 5
restored labels — still verified under the PRE_PHASE6 cap (94497 < 94519)
and satisfying #913's 7-label requirement.

* fix(#2650): bind {outputFile} from the real Agent() return — was dead code

Independent review blocker: PLANNER_OUTPUT_FILE/CHECKER_OUTPUT_FILE were
read by every gsd_stall_watch call but never assigned anywhere in the
diff. With the variable permanently empty, `[ -f "$output_file" ]` was
always false, marker_found could never become true, and marker_received
was unreachable — the marker-based detection path was permanently dead.

Worse for the plan-checker spawn specifically: a checker that PASSES
touches no *-PLAN.md files, so it had no working completion signal at
all without the marker path. A healthy plan-checker finishing cleanly in
two minutes would be declared stalled once planner.stall_threshold_minutes
elapsed and the recovery menu would fire on an already-succeeded agent —
worse than the original unbounded hang.

Fixed by replacing the dead bash variable with the `{outputFile}`
orchestrator-substitution token, the same convention docs-update.md:471
already uses for a real run_in_background=true Agent() return ("Read
tool: file_path: `{outputFile from README agent result}`"). This is a
net BYTE SAVING at each site (`"{outputFile}"` is shorter than
`"$PLANNER_OUTPUT_FILE"`), which funded moving the full binding
explanation — including why plan-checker's *-PLAN.md glob alone is not
a working completion signal — into the lazily-loaded reference file to
stay under the frozen PRE_PHASE6 cap (94496 bytes, 22 headroom; net +13
over baseline, acknowledged in tests/emitted-drift-acks/2650-plan-phase-
stall-detection.json).

Added a regression test asserting plan-phase.md itself binds {outputFile}
at all 5 spawn sites and contains no dangling $PLANNER_OUTPUT_FILE /
$CHECKER_OUTPUT_FILE reference — the previous test suite only exercised
gsd_stall_watch's behavior when handed a valid argument, which is why
the dead production wiring survived two rounds of review. Also fixed
tests/fix-2650-plan-phase-stall-detection.test.cjs:170-195's raw
try/finally to use t.after(), per CONTRIBUTING's test-cleanup convention.

* chore(#2650): backfill changeset PR number to 3015

* fix: normalize CRLF at the read boundary in all .md-bash-extraction tests

Maintainer-authorized scope expansion, folded into this PR rather than
deferred: the Windows CI lane on this PR's own tests/fix-2650-plan-phase-
stall-detection.test.cjs exposed DEFECT.TEST-SHELL-PIPELINE-NONPORTABLE
(CONTEXT.md; recurring since #1700) as a repo-wide latent class, not a
one-off. Ten test files parse a fenced ```bash block out of a workflow
.md file and execute it via spawnSync/execFileSync; a Windows checkout
can yield CRLF line endings despite .gitattributes eol=lf, and bash then
treats the trailing \r on every extracted line as part of the token —
"unexpected EOF while looking for matching `"'" or a bare syntax error,
partway through the script.

Added tests/helpers.cjs:readFileNormalized() — strips \r\n -> \n at the
read boundary, before any fence-slicing or regex runs, so every
downstream operation is correct by construction. Migrated all ten call
sites to it:

Previously broken (fs.readFileSync with no normalization anywhere
between read and spawn):
- tests/worktree-cleanup.test.cjs (extractCwdGuardBash) — also fixes a
  misleading comment claiming the fence regex alone was "CRLF-safe"; it
  protected only the fence delimiters, never the captured body.
- tests/new-milestone-clear-phases.test.cjs (extractFenceBetween,
  extractFenceContaining)
- tests/code-review-pipeline-regression.test.cjs (extractPostProcessingScript)
- tests/drift-detection.test.cjs (readGate/bashBlock, plus the snippet-file
  comparison read in the same test)
- tests/graphify-visualization.test.cjs (extractStep3Block)
- tests/pause-work-improvements.test.cjs (extractCheckBlock)
- tests/plan-review-convergence.test.cjs (extractReviewerFlagsParseBlock
  and the inline post-config-gate resolution-block slices)

Already correct (split(/\r?\n/) then join('\n')), migrated to the shared
helper for consistency rather than a fourth/fifth/sixth copy of the same
fix:
- tests/git-base-branch.test.cjs (extractHandleBranchingBash)
- tests/quick-branching.test.cjs (extractStep25Bash)
- tests/runtime-launcher-parity.test.cjs (extractResolverSnippet)

Verified against a simulated Windows CRLF checkout (not assumed): for
both the worktree-cleanup.test.cjs and new-milestone-clear-phases.test.cjs
extraction shapes, confirmed the pre-fix code produces a real bash syntax
error on CRLF input and the post-fix code does not.

One eslint follow-up: local/no-crlf-fragile-split statically flags any
bare `\n` inside a markdown-fence-shaped regex, regardless of whether the
receiver was already normalized — it cannot see the readFileNormalized()
data-flow. Kept `\r?\n` in extractCwdGuardBash's fence regex (redundant
but harmless on pre-normalized input) rather than fight the rule.

Scope note: this diff is broader than issue #2650's own change (plan-
phase.md stall detection) because the Windows lane surfaced a genuine
repo-wide defect class while verifying that fix, and the maintainer
authorized fixing it here rather than filing it separately and shipping
a known-broken pattern.

Runtime impact: none — this is a test-harness-only defect. The live
orchestrator (Claude Code or another runtime) does not do a byte-exact
extract-and-pipe of .md content into a shell the way these tests do; it
reads the instructions and generates its own bash invocation text, which
does not reproduce a raw CRLF pass-through the same way.

Not touched: tests/plan-review-convergence.test.cjs's separate, tracked
spawnSync ETIMEDOUT flake under bench load (#3005, reproduced on
unmodified next) — unrelated load-sensitivity, not a CRLF symptom.

* fix(#2650): remove stale drift-ack fragment — plan-phase.md is self-explaining

tests/emitted-drift-acks/2650-plan-phase-stall-detection.json acknowledged
plan-phase.md's own emitted-path hash move, but plan-phase.md is directly
edited in this diff. Per the emitted-attribution law (ADR-2719,
tests/emitted-attribution.test.cjs), a workflow's emitted key equals its
own source path (gsd-core-verbatim identity rule), so a direct edit to the
source is self-explaining and auto-attributed — no ack was ever needed.

Verified via the pre-merge lint (scripts/lint-emitted-drift-ack.cjs, run
through npm run lint:ci with a fully cleared eslint cache): it passes clean
with the fragment removed, confirming no contradiction between the lint and
the runtime attribution gate — this was simply an unnecessary fragment.

* fix(#2650): restore plan-phase.md drift-ack — size ratchet demands it against next

tests/emitted-drift-acks/2650-plan-phase-stall-detection.json was deleted in
the previous commit because, against an earlier verification base, it was
inert: it explained a moved emitted hash that a direct edit to plan-phase.md
already self-attributes. Against origin/next@f1af47766a the demand is
different: plan-phase.md is 13 bytes larger than the base copy, which trips
the emitted-attribution size ratchet — a job this same ack also performs.

Recreated in the documented shape, keyed on the bare filename plan-phase.md
(not the full path, and not restating the byte delta per review guidance),
describing the actual change: the {outputFile} binding fix for the dead
PLANNER_OUTPUT_FILE/CHECKER_OUTPUT_FILE variables and the 5 restored
ORCHESTRATOR RULE labels required by #913, both at the stall-watch spawn
sites, with explanatory bodies living in the lazily-loaded
gsd-core/workflows/plan-phase/steps/stall-detection-helpers.md reference.

Confirmed no other fragment (on this branch or on next) claims the bare key
"plan-phase.md" before recreating — scripts/lint-emitted-drift-ack.cjs's
duplicate check is an exact string match, and the only other mention of
plan-phase.md in tests/emitted-drift-acks/ (2658-trae-instruction-file-path.json)
uses the full path as its key, so there is no collision.

* fix(#2650): real cause of Windows CI failure — bash -c argv-transport, not CRLF

The CRLF diagnosis for PR #3015's Windows failure was wrong. Proven wrong,
not assumed: .gitattributes' blanket `* text=auto eol=lf` means a Windows
checkout never receives CRLF for stall-detection-helpers.md, and the
extracted fence's line 64 is byte-identical and correctly balanced on every
platform. The real cause: runShouldRecover() passed a 70+ line, quote-dense
script as ONE argv element to `spawnSync('bash', ['-c', script, arg0, ...])`
PLUS four more positional args. Windows has no execve — Node serializes
that whole argv into a single CreateProcess command-line string, and Git
Bash's MSYS layer re-splits and unescapes it with its own rules. The
boundary between the script and the trailing args was not stable across
that round trip (live evidence: one failure's stderr was prefixed
`gsd_stall_should_recover_test:` — arg0 arrived — another `/usr/bin/bash:`
— arg0 did not).

Fixed by writing the script to a temp file and running `bash <file> <args>`
instead — the four values are now normal, quote-free positional args, and
the script itself never enters argv transport at all. Mirrors
tests/quick-branching.test.cjs's extractStep25Bash/runStep, which already
uses this exact shape and is green on Windows on `next`.
tests/worktree-cleanup.test.cjs's extractCwdGuardBash/runGuard stays on
`bash -c` but never appends extra positional args beyond the script itself,
so it never hits the same boundary — checked both siblings per review, not
assumed.

Corrected the now-actively-misleading CRLF comment in
extractStallHelpersBash(), and corrected the changeset's claim that the
repo-wide CRLF-normalization fix (folded into this branch, maintainer-
authorized) explains this PR's own Windows failure — it doesn't, though it
remains defensible on its own merits as general test-portability hardening.

Separately, while auditing the shipped (non-test) gsd_stall_watch for
Windows portability per review request, found and fixed a second, real
user-facing defect: the artifact-freshness check used GNU find's
`-newermt "@<epoch>"` shorthand, which the BSD find(1) actually shipped on
macOS does NOT understand ("Can't parse date/time: @<epoch>", verified live
against /usr/bin/find on both a stale and a genuinely fresh file). With the
adjacent `2>/dev/null`, that failed silently and permanently degraded
artifact_fresh to false on every macOS run — a plan-checker or planner
actively writing plan files could still be reported "stalled." Replaced
with `find $glob -mmin -N` ("modified less than N minutes ago"), which
needs no date-string parsing and is supported identically by GNU find and
BSD find; verified live that the old shape fails and the new shape passes
against the same real fresh file. Added a real-execution regression test
(gsd_stall_watch with `sleep` stubbed to a no-op so the test doesn't
actually wait, but the real `find ... -mmin` line still runs) proving the
fix, replacing the prior "not integration-tested" note for that path.

Note: the remote gsd-test runner is Linux-only, so it cannot itself confirm
the Windows fix — only the actual windows-latest CI lane can.

* fix(#2650): route the third bash -c call site through the same temp-file seam

runWatch() and a `-mmin` regression test still passed their script via
`bash -c <script>` after the previous commit only converted
runShouldRecover() — live Windows CI on 4b86cc57f confirmed the mechanism:
failures went 11 -> 4, and `full test (windows-latest, 22, shard 1/3)` and
`shard 2/3` flipped from fail to pass, but the remaining 4 failures (all in
this file, all still `bash: -c:`) were exactly the gsd_stall_watch describe
block, which runWatch() serves. runWatch() passes NO extra positional args
at all, so this also rules out the trailing-args theory from the prior
commit: the ~73-line, quote-dense script itself is what does not survive
Windows argv serialization when passed as a single `-c` element, regardless
of how many (if any) further argv elements follow it.

Extracted one shared runBashScript(script, args, opts) helper — write to a
fs.mkdtempSync'd file, run `bash <file> [args...]`, clean up in `finally` —
and routed all three bash-invoking call sites in this file through it
(runShouldRecover, runWatch, and the -mmin freshness test that builds its
own script inline for the `sleep` stub). One transport seam means a fourth
call site in this file cannot silently reintroduce the bug in isolation,
which is exactly what happened here with a second call site.

Corrected extractStallHelpersBash()'s doc comment a second time to state
the mechanism precisely (script content, not argv-element count) and cite
the live evidence (11->4 failures, shards 1 and 2 flipping green) so the
next reader does not have to rediscover it.

Audited every other bash-invoking call site in files this branch touches,
per review request:
- tests/code-review-pipeline-regression.test.cjs (runPostProcessing),
  tests/graphify-visualization.test.cjs (runBlock), and
  tests/drift-detection.test.cjs (two execFileSync('bash', ['-c', ...])
  sites, one of them carrying the same giant runtime-launcher preamble
  text) — all pre-existing, UNCHANGED by this branch (only touched for the
  readFileNormalized() CRLF swap), and already exercised on `next`'s last
  six Windows CI runs per the reviewer's own citation. Left as-is: no
  evidence of failure, and converting untested pre-existing code outside
  #2650's scope on an unverifiable guess would be its own risk.
- tests/git-base-branch.test.cjs (runHandleBranchingStep) and
  tests/quick-branching.test.cjs (runStep) already use the same temp-file
  pattern. No action needed.
- tests/runtime-launcher-parity.test.cjs (runResolver) uses `bash -c` but
  is explicitly `if (process.platform === 'win32') return '';` guarded off
  on Windows entirely, for an unrelated extension-less-PATH-stub reason —
  never reaches Windows argv transport at all. No action needed.
- tests/worktree-cleanup.test.cjs (runGuard) confirmed by the reviewer as
  correct and verified; not touched, per instruction.

Do not touch: the -mmin fix, the drift-ack fragment, the changeset — all
three confirmed correct in prior rounds and left untouched here.

Note: the remote gsd-test runner is Linux-only and cannot confirm this;
only the windows-latest lanes on #3015 can.

* fix(#2650): give runBashScript a default timeout

runShouldRecover() was the only one of the three call sites through
runBashScript() with no timeout — runWatch() and the -mmin test both pass
timeout: 10000 explicitly. Not a regression (this path never had a bound
before), but CONTEXT.md's unbounded-subprocess guidance applies directly,
and runShouldRecover() is driven repeatedly by a fast-check property test:
one pathological input that fails to terminate would hang CI indefinitely
instead of failing.

timeout: 10000 is now the helper's own default, with ...opts spread after
it so the two existing explicit timeout: 10000 call sites are unchanged
and any future caller inherits a bound automatically.

* fix(#2650): build the -mmin freshness test's glob with forward slashes

Windows CI on d6ddda6ea reported the last failure: the -mmin regression
test expected 'active' but got 'waiting' — find matched nothing, the same
silent-degradation shape as the macOS -newermt defect, but this time in the
test's own fixture rather than the shipped bash.

Traced what production actually passes: every gsd_stall_watch call site in
plan-phase.md builds artifact_glob as `"${PHASE_DIR}"'/*-PLAN.md'` —
PHASE_DIR is a POSIX-style .planning/phases/NN-slug value, and the whole
thing runs under Git Bash regardless of host OS, so production's glob is
always forward-slash. The test instead built it with
`path.join(tmp, '*-PLAN.md')`, which on Windows yields a backslash path
(C:\Users\RUNNER~1\...\*-PLAN.md). In bash pathname expansion a backslash
escapes the next character, so that pattern can never match a real path —
find silently returns empty under the existing 2>/dev/null, same shape as
the macOS bug. Confirmed as a test artifact, not a production defect:
production never constructs the glob this way, so no Windows user is
affected.

Fixed by forward-slashing the tmp dir before appending the glob suffix,
matching production's own convention, with a comment recording why (so a
future "simplify this back to path.join" edit doesn't silently reintroduce
the failure). The shipped bash's unquoted $artifact_glob is untouched —
quoting it would break the multi-file glob expansion it exists for.

Note: the remote runner is Linux-only and already passed clean at
d6ddda6ea (0/29,603, both node lanes); only the windows-latest lanes on
#3015 can confirm this fix.

* fix(#2650): forward-slash the three remaining runWatch globs (vacuous-pass CR)

The :353 fix (833c11da9) only converted the -mmin freshness test's glob.
Three sibling tests in the same describe block still built theirs with
path.join(tmp, '*-PLAN.md'), which yields a backslash path on Windows.

Two of those three were silently passing for the wrong reason: the
'-> stalled' and '-> waiting' tests both expect the glob to match nothing,
and on Windows a backslash path matches nothing regardless of whether the
directory is actually empty (bash eats each backslash as an escape before
the pattern is even evaluated). They would have passed identically with
glob expansion completely broken, which is a vacuous pass — not exercising
what they claim to. The third ('-> marker_received') is outcome-independent
of the glob, so it was merely inconsistent rather than wrong.

Converted all three to the same `${tmp.replace(/\\/g, '/')}/*-PLAN.md`
construction already used at the -mmin test, so every glob in the file now
matches production's own forward-slash `"${PHASE_DIR}"'/*-PLAN.md'` shape,
and the two negative tests are meaningful on Windows instead of accidentally
correct. Reworded the trailing comment on the 'stalled' test's glob line:
it now describes the fixture (the tmp dir contains no *-PLAN.md files)
rather than the pattern, since "matches nothing" read as a property of the
glob syntax when it's a property of what's on disk.

No assertion, the sleep stub, runBashScript, or the shipped bash changed.
Smoke-tested all three updated tests manually before committing (not via
node --test): marker_received / stalled / waiting, all correct.

* fix(#2650): fix own regression tests for #2993's plan-phase.md relocation

531101843's merge with origin/next brought in #2993 (unrelated, epic #1671
Phase 6.2), which extracted plan-phase.md's whole "Chunked Planning Mode"
section into gsd-core/workflows/plan-phase/steps/chunked-planning-mode.md,
leaving a <!-- gsd:section --> pointer behind. tests/plan-phase-drift-guard.
test.cjs (#913) was already updated to read the combined surface (host file
+ every steps/*.md) so its label count didn't go blind — my own #2650
regression tests were not, and searched plan-phase.md alone for the two
chunked spawn sites' headings, which no longer exist there. Two tests
failed outright (indexOf returning -1); a third ("standard planner spawn")
was silently weakened to an unbounded slice-to-EOF by the same relocation,
since its own end-boundary heading also moved — passing by accident rather
than by testing what it claimed.

Promoted the drift guard's local readPlanPhaseCombined() to a shared,
exported tests/helpers.cjs readWorkflowCombined(workflowPath) (host file +
sorted steps/*.md, CRLF-normalized at the read boundary) so a second,
divergent implementation is never written — the drift guard now delegates
to it via a same-named local wrapper, unchanged at every existing call site.

Fixed the three affected tests in tests/fix-2650-plan-phase-stall-detection.
test.cjs:
- "standard planner spawn (step 8)": end boundary changed from the now-gone
  "## 8.5. Chunked Planning Mode" heading to "## 9. Handle Planner Return",
  which still exists in plan-phase.md.
- "chunked outline spawn (8.5.1)" / "chunked per-plan spawn (8.5.2)": now
  read gsd-core/workflows/plan-phase/steps/chunked-planning-mode.md
  directly (not the generic multi-file combined blob, whose file-sort
  ordering would put unrelated step files between 8.5.2's slice and any
  downstream anchor) — the same heading-to-heading slicing as before still
  works because the file is small and self-contained.
- Extended the "no unbound $PLANNER_OUTPUT_FILE/$CHECKER_OUTPUT_FILE" check
  to also scan chunked-planning-mode.md, since two of the five spawn sites
  now live there.
- Added a new count-based test asserting exactly 5 (not "at least one")
  `gsd_stall_watch "$TS" "{outputFile}"` invocations across the combined
  surface, mirroring #913's own label-count guard, so every one of the five
  spawns stays provably bounded and a future relocation can't silently drop
  one without a test noticing.

Also added a small positive test that plan-phase.md's <!-- gsd:section -->
pointer to chunked-planning-mode.md exists (#2993 is unrelated to #2650 but
its presence is now load-bearing for where 2 of the 5 spawn sites live).

Audited every other test file in the repo for a stale reference to content
#2993 relocated (searched for the moved headings/prose and for
"chunked-planning-mode"/"CHUNKED_MODE" across all *.test.cjs): only this
file and the drift guard needed changes.
tests/issue-2762-plan-reviews-chunked.test.cjs already reads
chunked-planning-mode.md directly (brought in correct by the same merge).
gen-section-manifest.test.cjs, init.test.cjs, and workflow-fragments.test.cjs
reference "chunked-planning-mode" only as a manifest/section-id fixture
value for #2993 itself, not as a stale pointer to relocated content.

Did not touch: the ported ORCHESTRATOR RULE lines, run_in_background=true,
the glob constructions, runBashScript, the -mmin change, the timeout
default, or the drift-ack fragment (confirmed correct against the stale
local `next` ref two rounds ago and left alone).

ad3b9ec486 chore(#1671): fragmentize plan-phase.md and repair flag forwarding to the init bundle — Phase 6.2 (#3019)
* chore(#2993): fragmentize plan-phase.md onto the fragment model

Epic #1671 Phase 6.2. plan-phase.md is the largest workflow in the repo and
carried zero markers; it was deferred out of the Phase 3 pilot for two
reasons, both now dead. The 36-byte PRE_PHASE6 headroom was never the
blocker it looked like — fragmentizing is net-negative on host source, so
the trim is what creates the room. The --mvp interleaving was resolved by
measurement in #2992 and no sub-line mechanism is built.

- widen WHEN_VOCABULARY 14 -> 19 via a second coordinated ADR-1671
  amendment: flag:--ingest, flag:--prd, flag:--research-phase,
  flag:--reviews, state:chunked-mode
- state:chunked-mode is `--chunked` OR config workflow.plan_chunked, and
  that disjunction is resolved in the FACT, never in the grammar, so a
  compound condition never becomes an operator
- parse the new flags on the plan-phase route; extract six gated bodies to
  gsd-core/workflows/plan-phase/steps/ behind manifest-gated stubs
- prd-express-path.md was already extracted but read unconditionally; its
  wrapper is now gated, so the existing extraction finally pays off

plan-phase.md 94,483 -> 87,575 bytes (cap 94,519): headroom goes from 36
bytes to 6,944.

Also closes a surfaced docs gap: five real plan-phase flags (--chunked,
--skip-ui, --bounce, --skip-bounce, --granularity) were documented in
neither the argument-hint nor help. Making --chunked load-bearing without
fixing its siblings would leave the defect class half-open.

Refs #2993

* fix(#2993): forward flags to the init bundle so section gating actually fires

Blocker found by the correctness review, confirmed directly, and missed by
both the isolated reviewer and every test in this branch.

Neither workflow forwarded its flags to the init CLI:

  plan-phase.md:71    INIT=$(gsd_run query init.plan-phase "$PHASE" $GRAN_PARAM)
  execute-phase.md:84 INIT=$(gsd_run query init.execute-phase "${PHASE_ARG}")

So every flag: atom was permanently false in production and its section
permanently excluded. For plan-phase that made the PRD express path
UNREACHABLE — a regression, since it was an unconditional read before.
For execute-phase this is PRE-EXISTING: #2932 shipped `flag:--wave` gating
that has never once been true, so `--wave` silently dropped its own
wave-filtering guidance. Fixed here under the no-defer rule.

Why every test missed it: they drive the init CLI directly with flags,
which works. Production goes through the workflow's bash line, which did
not pass them — the exact "assert against the shape production uses" trap
this branch's own test matrix warns about.

- parse and forward --prd/--ingest/--research-phase/--reviews/--chunked
  (plan-phase) and --wave (execute-phase), using the anchored regex idiom
  the neighbouring GRAN_PARAM line already uses
- add a regression guard DERIVED FROM THE MANIFEST: for every flag:--X
  section, the owning workflow's init line must forward --X. It fails
  against the pre-fix files and covers any future atom, rather than
  spot-checking today's six.

Verified through the workflow shape, not the CLI shape: `3 --prd spec.md`
now yields ["prd-express-gate"] (was []), `2 --wave 2` yields
["partial-wave"] (was []).

Refs #2993

* test(#2993): acknowledge the execute-phase ripple and regenerate install-tree fixtures

Remote matrix was red with 46 unique failures, identical on both lanes.
Both causes are mechanical consequences of changing shipped workflow
content, and neither is visible to any local gate.

- emitted-attribution: execute-phase.md grew 163 bytes from the WAVE_PARAM
  forwarding fix and was unacknowledged, while the ack fragment named
  plan-phase.md, which SHRANK and therefore needed no ack at all — a stale
  entry is itself a failure. The reason now names the real ripple.
  The entry had to merge into the existing 2930 fragment: the ack linter
  does unconditional cross-fragment duplicate-key detection with no
  spent/live exception, so a second fragment declaring execute-phase.md
  collides even when the first is already merged and inert. Resolved per
  the linter's own guidance and that file's precedent of appending
  successive ripple reasons to one entry.
- golden-install-tree: tests/fixtures/install-tree/*.json are committed and
  deliberately excluded from the ADR-2719 attribution cutover, so they must
  be regenerated when shipped tree content changes. Regenerated after
  build:lib per the ordering landmine. 19 runtimes each gained exactly the
  six new plan-phase step files; zero paths removed, which is the absolute
  failure shape those fixtures exist to catch.

Refs #2993

* fix(#2993): restore the launcher preamble in an extracted step and follow moved content in its drift guards

Second red run: 26 unique failures, identical on both lanes, in two classes.

RUNTIME BUG (runtime-launcher-parity, 7 failures) — chunked-planning-mode.md
calls gsd_run but carried no canonical launcher preamble, which is what
DEFINES gsd_run(). On any non-Claude runtime that step would fail outright.
The preamble is now copied verbatim from the canonical source of truth,
gsd-core/workflows/_runtime-launcher.snippet.sh, and the fence dedented to
column 0 to match the prd-express-path.md sibling (a list-continuation
indent breaks the byte-equal preamble match). prd-express-path.md already
had a correct one. This is the same defect #2932 hit when it extracted
steps; the parity test caught a real bug, not a stale assertion.

DRIFT GUARDS (plan-phase-drift-guard, issue-2762-plan-reviews-chunked,
skill-frontmatter-contract) — these assert plan-phase.md contains content
this branch moved into step files. Retargeted at where the content now
lives, with the asserted property unchanged; the ALL-RUNTIMES label COUNT
test now reads host + every step file so the count is preserved across the
split rather than reduced. Each retargeted guard was verified to still fail
when its step file is stripped, so none was weakened into vacuity.

No emitted-drift ack was needed: currentSizes() enumerates
gsd-core/workflows/*.md non-recursively, so files under
plan-phase/steps/ are never in the size ratchet's scope.

a987cf2731 chore(#2932): emit a per-invocation section manifest from the init bundle (#2987)
* chore(#2932): emit a per-invocation section manifest from init

Extends the init bundle with a typed per-invocation section manifest so an
invocation loads only the branch guidance it will actually take.

The three flag/state-gated branches in execute-phase.md move into their own
step files; the parent keeps its gsd:section markers wrapping a one-line
on-demand reference, so each section's prose lives in exactly one file and
the parent shrinks 93369 -> 89507 bytes. A new drift-guarded generator
derives the shipped section manifest from those markers, and a new pure
evaluator maps invocation facts to applicable section ids.

The evaluator is a lookup over the frozen WHEN_VOCABULARY, never a parser
(Greenspun's Tenth Rule, ADR-1671:69); a parity test asserts the vocabulary
and the predicate map stay exhaustively in sync.

Closes #2932

* fix(#2932): fail closed on prototype-chain when values

An isolated adversarial review found WHEN_PREDICATES[section.when] was a
bracket lookup on a plain-prototype object, so inherited Object.prototype
members resolved as predicates: "constructor"/"toString"/"valueOf"/
"hasOwnProperty" returned truthy and SILENTLY INCLUDED the section, and
"__proto__" threw an untyped TypeError carrying no .reason. Both violate
the module's documented fail-closed contract, and the manifest is read from
disk at run time so it cannot be assumed trustworthy.

Builds the predicate map on a null prototype and guards the lookup with an
explicit Object.hasOwn check. Adds table-driven coverage for nine
Object.prototype-shaped keys asserting the TYPED reason (asserting only
that it throws would still pass while broken) plus a fast-check property
injecting a hostile value at an arbitrary document position.

c61dd49d95 enhance(#2255): blocking catastrophic-shrink guard for curated .planning/ writes (#2301)
* feat(#2255): blocking catastrophic-shrink guard for .planning writes

Adds hooks/gsd-write-guard.js, a PreToolUse hook that hard-blocks
(decision: 'block', exit 2) a whole-file Write collapsing a curated
.planning/ artifact (ROADMAP.md, .planning/milestones/*-ROADMAP.md,
STATE.md) below 40% of its on-disk line count. Files under 40 lines
are exempt; GSD_ALLOW_PLANNING_SHRINK=1 (named in the block message)
bypasses for legitimate milestone resets.

Fix 3 of #973 — the only defense independent of per-agent tool config.
Registered on the Claude plugin surface (hooks.json), settings-json
runtimes (runtime-hooks-surface.cts, self-contained pattern), Kimi
spec, and the OpenCode/Kilo plugin buses. Golden install fixtures and
INVENTORY regenerated; regression tests negative-controlled (16/16
RED with the hook absent, 16/16 GREEN with it present).

* chore(#2255): backfill changeset pr number to 2301

* enhance(#2255): address review — fail-closed reads, typed block output, registration, property test

Review fixes for trek-e's CHANGES_REQUESTED on PR #2301:

- Blocker 2: register gsd-write-guard.js in BUNDLED_GSD_HOOK_FILES
  (no-shipping-drift test).
- Blocker 3: update the always-on hook enumerations in ADR-766 and
  CONTEXT.md from six to seven.
- Major 4: fail CLOSED on non-ENOENT read errors — only a missing file
  (new-file Write) passes; EACCES/EISDIR/ELOOP/etc now block, with a
  typed readError field and the override still honored. Tested, with a
  negative control against the pre-fix hook.
- Major 5: fast-check property test for the SHRINK_RATIO/FLOOR_LINES
  budget contract (blocked ⟺ newLines < oldLines*SHRINK_RATIO above the
  floor; sub-floor always exempt), boundary examples pinned.
- Major 6: block output now carries typed oldLines/newLines/
  overrideEnvVar fields; tests assert on those instead of regexing the
  free-form reason string.
- Minor: CURATED_PATTERNS are case-insensitive (case-insensitive-FS
  bypass on macOS/Windows); limit+1 boundary tests added for both the
  floor and the ratio.

* enhance(#2255): engage the write guard on Kimi's native payload shape

The guard shipped with Claude-vocabulary checks (tool_name 'Write',
tool_input.file_path), which #2304 showed leaves a guard dormant on
Kimi: the [[hooks]] matcher is registered pre-translated but kimi-cli
forwards its native payload verbatim — tool_name 'WriteFile' (bare or
module-qualified) and tool_input.path per its tool schemas
(src/kimi_cli/tools/file/write.py). The guard matched, saw an unknown
name, and exited 0.

Apply the same per-guard normalization PR #2326 gives the three
sibling guards (name + field mapping, inlined — hook scripts stage as
standalone files), and write the block reason to stderr as well as
stdout JSON: Kimi feeds stderr, not stdout, back to the model on
exit 2, so a stdout-only reason blocks without telling the model why
or naming the documented override.

Regression tests pipe Kimi-shaped payloads (engage, qualified-name,
stderr-reason) plus exemption pins (StrReplaceFile stays out of scope
by design; non-curated paths pass) — verified red against the pre-fix
guard, green after.

* enhance(#2255): rebase onto next; regenerate golden-parity fixtures

* enhance(#2255): wire the escape hatch into complete-milestone's reorganize step

Review Blocker 1: the guard hard-blocked /gsd:complete-milestone's ROADMAP
reorganize — the tree's only legitimate milestone reset and the exact caller
GSD_ALLOW_PLANNING_SHRINK was built for. The reorganize step now performs the
rewrite through a shell write with the hatch set on the command (a hook
inherits the runtime env, so a bare Write cannot carry a per-step override),
and a binding test derives the env var name from the guard's typed output and
asserts (a) the workflow step sets it and (b) the guard passes the identical
catastrophic payload under it — so the next complete-milestone.md edit cannot
silently re-break the wiring.

* enhance(#2255): drop dead Edit-class mapping from normalizeKimiPayload

Review Major 1: StrReplaceFile -> 'Edit' and the old_string/new_string
reconstruction were unreachable-by-effect — the guard exits 0 for any
tool_name !== 'Write', so nothing ever read the fields they set, leaving
guaranteed-surviving mutants against the Stryker bar. The map now carries
only WriteFile -> 'Write'; the StrReplaceFile exemption test message states
the fall-through it actually exercises.

* enhance(#2255): review minors — American spellings; writeSync before exit(2)

Minor 1: normalised/normalise -> American house style. Minor 2: the two
block paths wrote stdout+stderr via async pipe writes then exit(2) —
async-on-Windows, unflushed at exit; fs.writeSync(1/2, ...) makes the block
payload durable.

* enhance(#2255): assert stderr equals the typed reason, not raw prose

Minor 3: the last raw-text match in the suite pinned override-name prose on
stderr. The contract is "stderr carries the reason Kimi feeds back" — now
asserted as stderr non-empty and byte-equal to the parsed stdout.reason.

* enhance(#2255): bind the write-guard's Kimi normalization into the parity test

Review Major 2: the guard's normalizeKimiPayload is a 4th inlined copy with
nothing binding it. This extends PR #2326's kimi-guard-normalization-parity
test (same path and helpers, authored as a superset so either merge order
resolves cleanly): sibling byte-parity is existence-gated zero-or-all —
trivially green until #2326 lands, full-strength after — and the write-guard
copy is bound semantically (map is the value-inverse of convertKimiToolName;
the Kimi name for Write must map, or the guard is dormant on Kimi; the
path -> file_path half must be present). Byte-parity is deliberately not
asserted for this copy: it legitimately omits the Edit-class mapping
(Major 1 — dead code in a Write-only guard).

* enhance(#2255): refresh golden-parity fixtures for revised guard + workflow

* chore(#2255): regenerate golden fixtures after rebase onto next

The committed fixture hashes were generated against a tree predating
next's latest 11 commits, which independently modified the same
install-parity surface. Rebased onto next and regenerated with
`npm run gen:golden`.

Verified: against upstream/next the regenerated fixtures differ by
exactly this PR's own entries -- hooks/gsd-write-guard.js (new),
hooks/managed-hooks-registry.cjs, plugins/gsd-core.js, and
gsd-core/workflows/complete-milestone.md. No unrelated drift.

* fix(#2255): regenerate workflow size baseline for complete-milestone

`complete-milestone.md` grew 31071 -> 32061 (+990) when the round-2
review fix bound GSD_ALLOW_PLANNING_SHRINK=1 into the reorganize step,
but tests/workflow-size-baseline.json was never regenerated. The
per-file workflow baseline test (issue #1074) failed on
ubuntu-latest/22 and both macOS shard 1/3 jobs.

The growth is justified: it is the escape-hatch binding requested in
review round 2 (the guard must not hard-block the tree's only
legitimate milestone reset), not incidental bloat.

Regenerated via `npm run size:baseline`; the diff is exactly the one
entry.

* chore(#2255): regenerate golden fixtures and size baseline after rebase onto next

* enhance(#2255): bind the shrink escape hatch mechanically — single-use sentinel the guard consumes

Round-5 M1: the per-step `GSD_ALLOW_PLANNING_SHRINK=1 tee` prefix was inert
(no PreToolUse hook exists on Bash in this family; the write succeeded by
dodging the guard, not by the override firing) and the protection was prose.
The hatch is now a transport code consults: complete-milestone's reorganize
step arms `.planning/.gsd-allow-shrink` with the target's path, keeps the
Write tool as the sanctioned path, and the guard — at the block point only —
verifies the sentinel is fresh (15 min) and names the pending target, then
CONSUMES it and allows that one write. Path-bound + single-use + freshness
keep it from becoming a standing unlock. The env var remains as the
interactive transport, where it can actually reach the hook.

Regression tests written first (negative control: 3 failed pre-fix): the
armed-sentinel Write passes and consumes; stale does not exempt; a token for
a different file neither exempts nor is consumed; the binding test now takes
the sentinel name from the guard's typed output (overrideSentinel), asserts
the step arms it, and asserts the step no longer routes the rewrite around
Write via a shell pipe.

Also in this commit, same file:
- m2: block emission is exception-safe — emitBlock() wraps both writeSync
  sites in their own try/catch that still exits 2, so an EPIPE can no longer
  convert fail-closed into the outer catch's fail-open.
- Header discloses the two reviewed design limits (cumulative sequential
  shrink; lexical match vs symlinked paths) per round-5 scoping.

* docs(#2255): document the sentinel transport across guard surfaces; changeset ends with the (#2255) parenthetical (m4)

USER-GUIDE bullet, INVENTORY row (en + ja/ko/pt/zh), the
runtime-hooks-surface registration comment, and the changeset now describe
both hatches — the single-use sentinel for workflow steps and the env var
for interactive use — instead of implying a per-step env can reach a hook.
The changeset's trailing `Resolves #2255.` prose becomes the `(#2255)`
parenthetical the repo's fragments use (round-5 m4).

* chore(#2255): regenerate derived families on the rebased tree (full sweep)

Full generator sweep after rebasing onto next @ the body-parser-patched
lockfile: build, gen-inventory-manifest, gen:golden, size:baseline. Every
regen delta verified to be either a PR-owned entry (gsd-write-guard.js,
complete-milestone.md, INVENTORY/USER-GUIDE) or exact convergence to next's
committed value for entries our arbitrary-side conflict resolution had left
stale (all 18 runtime fixtures checked mechanically).

* test(#2255): use helpers.cleanup for sentinel teardown, not raw fs.rmSync

The repo's local/no-raw-rmsync-in-tests rule exists for the Windows-EBUSY
retry budget; the sentinel disarm now rides it like every other teardown.

* chore(#2255): regenerate derived families after rebase onto next

Full sweep on the rebased tree (build -> gen-inventory-manifest ->
gen:golden -> size:baseline). Every delta is either a PR-owned entry
(hooks/gsd-write-guard.js, its registration surfaces
hooks/managed-hooks-registry.cjs and the two plugin buses,
gsd-core/workflows/complete-milestone.md) or exact convergence to
next's committed value across all 18 runtime fixtures.

* chore(#2255): regenerate derived families after rebase onto next @ a5180d96

Rebase onto current `next` (a5180d96) resolved 12 conflicting
golden-install-parity fixtures; all regenerated via the full generator
sweep (build, gen:golden, size:baseline) rather than a single generator.

`lint:generated-sync` reports every generated artifact in sync. All 45
differing fixture keys and the single workflow-size-baseline entry map
to files this PR actually touches; no foreign drift.

* fix(#2255): remove the stale unguarded reorganize_roadmap step (round-8 blocker)

complete-milestone.md carried a second ROADMAP-collapsing step,
`reorganize_roadmap`, distinct from the sentinel-armed
`reorganize_roadmap_and_delete_originals` this PR wired. It is a vestige
of the pre-archive-then-reorganize design: it sits BEFORE
archive_milestone, so executing it as written would collapse ROADMAP.md
before the archive snapshots the full phase detail — and its Write is
exactly the shape gsd-write-guard hard-blocks, with no hatch armed. The
file's own success criteria describe only one reorganize outcome
(Backlog-preserving, overwrite-in-place — the later step's properties),
and archive_milestone points forward to "the reorganize step".

Removed rather than wired, per the round-8 review's confirm-and-remove
option. A new binding test asserts the sentinel-armed step is the ONLY
reorganize step in the workflow, so an unguarded collapse step cannot be
silently reintroduced (negative-controlled: fails against the pre-fix
tree). Golden-parity fixtures and the size baseline regenerate for the
shrunk file; every changed fixture key is complete-milestone.md's own.

* test(#2255): document why the read-error injection is a path collision, not an fs monkeypatch

Round-8 nit: the non-ENOENT tests inject via a directory-at-target-path
collision instead of the repo's fs-method monkeypatch pattern. That is
deliberate, not drift — runHook exercises the hook as a spawnSync child
process, so an in-process fs.readFileSync patch (the pattern the cited
siblings use on require'd, in-process code) can never reach the code
under test. Record the reasoning at the injection site.

* chore(#2255): regenerate derived families after rebase onto next @ 0d08c320

Rebase onto current next (0d08c320) for the CONFLICTING/DIRTY state. All 32
conflicts were generated artifacts (19 golden-install-parity, 12 install-tree,
workflow-size-baseline); resolved arbitrarily and regenerated via a full
generator sweep (build, gen:golden, size:baseline, gen-inventory-manifest)
rather than hand-merged. No source conflicts.

Regen diff verified against the PR's changed-file set: 7 distinct differing
keys, all PR-owned (gsd-write-guard.js, managed-hooks-registry.cjs,
plugins/gsd-core.js, complete-milestone.md, and their .kimi mirrors).
lint:generated-sync clean.

* chore(#2255): regenerate derived families after rebase onto next @ 9138271b

Conflict set was 20 paths, every one a generated artifact, zero source
conflicts — resolved arbitrarily during the replay and regenerated here,
per the maintainer's round-9 recipe (never hand-merged).

Generator sweep (not just gen:golden): npm run build, gen:golden,
size:baseline, gen-inventory-manifest, gen:registry. INVENTORY-MANIFEST
came back byte-identical, so the merged value was already correct.

Regen diff verified == PR-touched entries: every differing leaf key
attributes to a file this PR changes (complete-milestone.md, the guard,
managed-hooks-registry.cjs, both plugin buses) — derived from the
changed-file set, not a feature-name filter.

* fix(#2255): port the #2595 Kimi-payload hardening the base landed for the sibling guards

Self-found via the round-10 base sweep: a8b40fa5 (#2547/PR #2595) hardened
gsd-prompt/read/worktree-path-guard's normalizeKimiPayload after this PR was
authored, and this guard carried all three pre-fix shapes:

- `path` now wins outright over a model-supplied `file_path` — kimi-cli's
  WriteFile schema carries no `file_path`, so a payload pairing a curated
  `path` with a spurious `file_path: ""` had the guard reading '' and
  exiting 0 while kimi-cli wrote to `path` (one-key bypass, no crash needed).
- null/primitive payloads pass through deliberately instead of throwing into
  the fail-open catch.
- the `file_path` read is typed (`typeof === 'string'`), closing the
  crash-to-allow on `[]`/`{}` — this is what the base-added
  kimi-guard-typed-payload-reads scan flags.

Negative-controlled: the shadowing payload exits 0 against the pre-fix guard
and 2 against this one.

* fix(#2255): round 9 Major 2 — stop printing the sentinel recipe in the agent-facing denial

The block message ended by telling the blocked agent exactly how to arm the
single-use sentinel — handing the #973 actor a mechanical self-authorization
in the moment it is blocked. The recipe is gone from the prose; the
corrective advice and the env override's name stay (the latter is a #2255
acceptance criterion, and a per-step env prefix cannot reach a hook anyway),
and the typed overrideSentinel field stays for the binding tests. The hatch
remains documented in USER-GUIDE.md and complete-milestone.md, where humans
and the workflow engine read.

* fix(#2255): round 9 Minors 1-2 — realpath-resolve the target before the curated match; disclose the /i Linux cost

Minor 1: a Write to a non-curated path that symlinks into a curated file was
not matched while writeFileSync followed the link — the target is now
realpath-resolved before the curated match (ENOENT keeps the lexical
resolution so new-file Writes still pass; any other realpath error falls
through to the read, which fails closed). Negative-controlled: the symlink
payload exits 0 against the pre-fix guard, 2 against this one. Test skips on
win32, where symlink creation needs privilege.

Minor 2: the header's design-limits block now names the unconditional /i
cost on case-sensitive Linux (a genuinely distinct .planning/roadmap.md is
also treated as curated) next to the stateless limit, and drops the closed
symlink limit.

* test(#2255): round 9 Minors 3-4 — CRLF counting pin + a passing Write leaves a fresh sentinel unburned

Minor 3: countLines' split('\n') is CRLF-safe for a count (the \r rides
along), confirmed by trace in the review — this pins it against this repo's
recurring CRLF regressions, on both sides of the compare and at the 40%
boundary.

Minor 4: consumeSentinelFor runs only after the ratio check would block, so
a within-tolerance Write never burns the workflow's token — true by
construction, previously un-asserted.

* fix(#2255): round 9 Major 3 — correct the stale env-var line in archive_milestone's summary

complete-milestone.md's "After archival" bullet still said the reorganize
happens "under GSD_ALLOW_PLANNING_SHRINK=1" — the wording from the round-2
design this PR's own history rejected in round 5 (a per-step env var cannot
reach a hook; setting it in a Bash step silently does nothing). It now points
at the sentinel mechanics the reorganize step actually documents, matching
that step and USER-GUIDE.md.

* docs(#2255): round 9 Major 1 — user-facing docs state the stateless per-Write limit

The changeset and USER-GUIDE described the guard as covering "catastrophically
shrinks" with no caveat, while the stateless design was disclosed only in the
hook header — an operator reading the shipped docs would conclude iterative
erosion is covered. Both surfaces now state the per-Write comparison and the
erosion non-goal explicitly, in line with what the guard does.

* fix(#2255): round 10 Blocker 1 — arm the hatch in the roadmapper's curated writes

gsd-roadmapper Step 7 Writes both .planning/ROADMAP.md and .planning/STATE.md
wholesale, and /gsd:new-milestone spawns it against the OUTGOING milestone's
files. new-milestone's `phases.clear` archives phase DIRECTORIES, never
ROADMAP.md, so nothing compacts it first, and no ordering rule forces
/gsd:complete-milestone to run before /gsd:new-milestone.

Measured against the shipped hook at the #973 file size (292 lines): a new
4-phase roadmap lands at 18.2% and an 8-phase one at 31.8% — both blocked; only
a 12-phase replacement (45.5%) clears. So the collapse is reachable on a
first-party flow, which is the failure mode #2255 para 4 says the guard must not
have.

Arms the single-use sentinel immediately before each Write, one per target
(the token is path-bound and single-use, so one arming cannot cover both), and
gates each arming on `[ -f ]` so the /gsd:new-project path — where the guard
already exempts via ENOENT — strands no unconsumed token.

Binding test derives the sentinel name from the guard's own typed output, so a
rename on either side fails the suite instead of silently unwiring the hatch.
Negative-controlled: 2 assertions fail against the pre-fix roadmapper.

* docs(#2255): round 10 Major 2 — scope the claim to the guarantee that ships

The sentinel is a plain file, so an agent that would reason past an advisory
can arm one with a single Bash call it is already permitted to make. The
"only defense independent of per-agent tool config" framing outran that, and
the changeset was on its way into CHANGELOG.md.

Retitles the claim on all three surfaces (changeset, guard header, USER-GUIDE)
to what the guard actually delivers: it blocks accidental and single-shot
collapse and is not a defense against a determined agent; what it converts is
"ignore a sentence" into "take one deliberate, path-bound, single-use,
auditable action".

Pinned by test on the DURABLE surfaces only — the guard header and USER-GUIDE.
The changeset fragment is deliberately not pinned: it is consumed at release,
so a test reading it would start failing the moment the release lands. The
bound-statement assertion normalizes comment markers and whitespace first, so
it pins the claim rather than the paragraph's line wrapping.

Negative-controlled: both assertions fail against the pre-fix surfaces.

* test(#2255): acknowledge the roadmapper growth from the round 10 Blocker 1 wiring

The emitted-attribution gate (#2719/#2767) flags gsd-roadmapper.md growing 1130
bytes without an acknowledgment. The growth is the Blocker 1 sentinel wiring
plus the rationale a future editor needs to keep it, so it gets an ack fragment
rather than a silencing regen — the gate's own message is explicit that there is
nothing left to regenerate.

Fragment is PR-scoped (2301-…) per the gate's naming instruction, and uses the
plain-string reason form the shipped fragments use.

Verified against the TRUE upstream tip, not the fork's origin/next: a stale
origin made this same gate report unrelated phantom drift (1 emitted path + 6
grown files + 5 stale acks) that vanishes when GSD_EMITTED_BASE is pinned.

* test(#2255): renumber the roadmapper PROSE_ALLOWLIST pin after the Step 7 wiring

CI red on shard 2/3, all four platforms. The #2751 gate keys PROSE_ALLOWLIST on
{file, line}; the Blocker 1 wiring added 18 lines above the allowlisted
parenthetical in agents/gsd-roadmapper.md, moving it 624 -> 642. Both halves of
the gate then fired: the moved line reads as a new offender, and the stale
entry no longer matches anything.

Line content at 642 is byte-identical to what the entry describes — a
descriptive "e.g." naming SDK queries a user could run — so this is a
renumber, not a re-classification.

Swept the defect class rather than the instance: agents/gsd-roadmapper.md is
the only line-pinned reference to any file this round changed.

Negative-controlled: both assertions fail against the un-renumbered allowlist.

cc3ee301a7 fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root (#2593)
* fix(#2544): stage the CommonJS marker in GSD-owned dirs, not the config root

installSharedHooksBundle wrote `{"type":"commonjs"}` over
<configRoot>/package.json unconditionally — no existence check, no merge,
no backup — on every install and every /gsd-update re-install. On the 11
affected runtimes that file is often user-owned; on OpenCode and Kilo it is
the documented place to declare local-plugin npm dependencies, so a user's
name/type/dependencies/scripts were destroyed on each run.

The uninstall path already read the file and unlinked it only on an exact
content match. That asymmetry was the defect: the discipline existed in the
codebase, it just was not applied on the write side.

Move the marker into the directories GSD creates and fills with its own .js
files — hooks/ (all shared-hooks runtimes, incl. Kimi's own root) and the
nativePlugin dir (plugins/ for OpenCode+Kilo, extensions/ for pi) — and stop
writing the config root entirely. New src/commonjs-marker.cts owns the marker
string plus one ownership predicate (absent / gsd-owned / foreign, fail-closed
on an unreadable file) shared by ensureCommonJsMarker and removeCommonJsMarker,
so install and uninstall cannot drift apart again.

Nothing else depended on the config-root marker: package identity is baked at
build time (#378/#498) and version resolution prefers gsd-core/VERSION and
already tolerates a missing root package.json (#1383) — Codex has installed
without one all along. A package.json in plugins/ or extensions/ is inert to
plugin discovery, which globs *.{ts,js} only (see installer-migration 006).

Uninstall retires the pre-fix config-root marker, so upgrading users are
cleaned up on removal, and still never touches a file it did not write.

* fix(#2544): point the changeset fragment at the filed PR

The fragment's `pr:` field is only knowable after `gh pr create` returns.

* fix(#2544): register commonjs-marker.cjs in the tsc-generated ESLint ignore set

bin/lib/commonjs-marker.cjs is tsc output (src/commonjs-marker.cts is the
linted source), so it belongs in the ADR-457 ignore list like its siblings.
Clears the lint-tests no-var failure and the repo-invariants
"linted xor ignored" migration-state test.

* fix(#2544): pin the kimi CommonJS marker to hooks/, not the ~/.kimi root

The UPGRADE 1 test still asserted the pre-#2544 marker location
(~/.kimi/package.json). The marker now lives inside ~/.kimi/hooks — the
directory GSD itself creates — matching the updated golden-install-parity
and install-tree fixtures. Also asserts the root marker is NOT written.

* fix(#2544): make the CommonJS marker write path non-fatal

Review round 2, Major 3 + Minor 1 + the stagedHooks nit.

ensureCommonJsMarker rethrew any non-EEXIST write error and neither call site
caught it, so EACCES on a read-only hooks/, EROFS, or ENOSPC aborted the whole
install with a raw stack trace. Every other marker interaction in the module is
best-effort — removeCommonJsMarker swallows unlink failures, classifyMarker
swallows read failures — and this was the write path, i.e. the one most likely
to fail on a locked-down config dir. It now returns a new 'failed' outcome and
both call sites warn and continue.

Sibling found while sweeping for the same defect class: fs.mkdirSync sat
OUTSIDE the try block, so an unwritable parent threw past the guard entirely.
Creating the directory is the same environmental hazard as writing into it, so
it moved inside.

Also in this file:

- The hooks marker is now gated on `stagedHooks && hooksOk`, not stagedHooks
  alone. stagedHooks is computed from the SOURCE listing before the copy loop,
  so it stays true when the copies land but verifyInstalled() then fails —
  marking a hooks/ GSD did not successfully populate claims an ownership the
  install did not earn.
- The uninstall rmdir of the native plugin dir is gated on GSD having actually
  removed something from it. Hoisting it out of the adapter-exists guard (so
  the marker-only case could prune) had silently widened it into deleting a
  user-created but empty plugins/ or extensions/ dir — the same "don't touch
  territory GSD didn't fill" principle this issue is about, inverted.
- Kimi's pre-#2544 marker at its native hook root (~/.kimi) is retired at the
  same call site that writes its replacement. That path is outside kimi's
  configDir, so installer-migration 007 structurally cannot reach it.

* fix(#2544): retire the stale config-root marker via installer-migration 007

Review round 2, Major 1 — the PR's headline claim was false for existing
installs. Upgraders kept BOTH markers: the new one under hooks/ and the stale
{"type":"commonjs"} at the config root, so their config root stayed pinned to
CommonJS and their dependency manifest stayed gone until they uninstalled.

The migration is unusual in one way, and it is the part worth reviewing: the
config-root marker was never recorded in gsd-file-manifest.json (writeManifest
records hooks/, agents/, commands/, scripts/ and the native plugin, never a root
package.json), so classifyArtifact answers 'unknown' for it and the planner's
own guard downgrades a remove-managed on an 'unknown' classification to
preserve-user. 007 therefore supplies the "purpose-built detector for an old
GSD-owned shape" that docs/installer-migrations.md#remove-managed sanctions —
exact content match, the same predicate removeCommonJsMarker has always used —
and declares the resulting classification on the action. A package.json with any
other content is left untouched, and there is deliberately no backup-and-remove
branch: a non-matching file here is not a patched GSD artifact, it is somebody
else's file.

Scope is all runtimes. The `runtimes` field is OMITTED rather than `[]`:
validateStringArray requires the field to be non-empty WHEN PRESENT, while the
runtime filter treats an empty array as "all" — so `runtimes: []` throws at plan
time and the migration never runs. The metadata test pins this.

Kimi is a deliberate carve-out, named in the migration's own header: its marker
lived at ~/.kimi, outside kimi's configDir, and migration relPaths are
structurally confined to configDir. It is retired by the installer instead.

Registration: shipped-migrations table, .gitignore for the emitted .cjs, the
EXPECTED_CHECKSUMS baseline, and the ESLint ignore set. That last one is not
copied from migration 006 by rote — 006 needs no entry because it imports
nothing, while 007 imports node builtins, so tsc emits its __importDefault
helper and the `var` in it trips no-var. This is the same lint gate that made
round 1 red.

* test(#2544): fault-injection and multi-runtime marker coverage

Review round 2, Major 2 + Minors 4 and 5.

Major 2 — CONTRIBUTING.md:514-531 is mandatory for install/uninstall flows and
the suite had no fs monkeypatching at all. Every branch now covered is one whose
doc comment claims it as the module's safety posture:

- classifyMarker non-ENOENT lstat error -> 'foreign' (the fail-closed rule),
  with an ENOENT control alongside it so the test discriminates rather than
  just asserting one side
- classifyMarker readFileSync throw -> 'foreign' (present-but-unreadable never
  downgrades to the permissive answer) — the fixture's bytes are exactly GSD's
  marker, so the test fails if the code ever answers on content it could not read
- a DIRECTORY at the marker path (CONTRIBUTING:521; the symlink case was already
  covered with a real symlink, the directory case needs no injection at all)
- the ensureCommonJsMarker TOCTOU EEXIST branch — the entire reason for flag:'wx'
- the new 'failed' outcome, for both writeFileSync (EACCES/EROFS/ENOSPC) and the
  mkdirSync that used to sit outside the guard
- removeCommonJsMarker unlink throw -> false

These save and restore fs methods in `finally` rather than using chmod 0o000,
which does not fault under root and would pass vacuously in root Docker and CI.

Minor 4 — uninstall was driven for opencode only. pi's extensions/ and both
kimi locations now have behavioral coverage, install and uninstall, each paired
with a user-authored-file case proving GSD leaves it alone.

Minor 5 — the stagedHooks gate had no assertion behind its stated reason.
A pre-existing, GSD-untouched hooks/ directory is now driven through a runtime
that declares skipSharedHooksInstall and asserted to stay marker-free, with its
user content intact.

Also regression-tests the uninstall rmdir gate from the previous commit: an
empty plugin dir GSD removed nothing from must survive.

* docs(#2544): correct stale marker prose, register the module, document the trade-off

Review round 2, Minors 2, 3 and 6.

Minor 2 — six files asserted the installed ROOT ships the synthetic marker.
None was load-bearing (all three walk-up consumers are VERSION-first with
try/catch and the marker never carried a `version`), but ADR-457:52 is the
rationale for keeping a generated module, so a future reader would mis-derive
the constraint from it. Each site is corrected to what is now true: the
installed tree carries no package.json with a .name at all, because the only
ones GSD stages are {"type":"commonjs"} markers and they now live in GSD's own
directories.

Two of the six needed more than a location swap. hooks/gsd-check-update-worker.js
and the platform-gate test both described `require('../package.json').name`
resolving to undefined; post-#2544 that require does not resolve at all, so the
history is kept accurate and the present-tense claim corrected rather than just
moved. And src/runtime-artifact-conversion.cts described the no-root-package.json
case as Codex-only — it is now every runtime, which strengthens that comment's
own argument for lazy resolution. The generated .cjs sibling needs no edit: it
is gitignored build output, not a tracked file.

Minor 3 — src/commonjs-marker.cts had no CONTEXT.md entry, unlike every peer
module, and CONTEXT.md is the #2 co-change partner of bin/install.js. Added,
including the fail-closed posture and the never-throws contract.

Minor 6 — the plugins//extensions/ marker shadows the config root for all .js
siblings, so an OpenCode/Kilo user's ESM plugin/*.js stays broken. That is
exactly what #2544's Fix section prescribed and it is disclosed in the PR body,
but the PR body is not documentation. It now lives in the OpenCode section of
docs/how-to/install-on-your-runtime.md, stated as a real constraint rather than
a pure improvement, with the .ts mitigation and a fallback for ESM plugins.

* test(#2544): attribute the CommonJS marker in the emitted-provenance rules

The differential emitted-attribution gate (#2723, landed on `next` after this
branch was cut) went red on the macOS shards once this PR rebased onto it. Two
distinct causes, both real gaps rather than noise:

1. `plugins/package.json` and `extensions/package.json` matched NO rule — the
   `native-plugin` rule covers `*.{js,cjs,mjs}` only, so the marker read as an
   unattributed emitted family.
2. `hooks/package.json` fell through to `hooks-built`, which attributes an
   emitted `hooks/<X>` to a repo source `hooks/<X>`. There is no
   `hooks/package.json` in the repo, so it resolved to a nonexistent path.

Cause 2 is exactly the failure already documented three lines above it for
Copilot's `gsd-session.json` — "a code literal, not a built script" — so the fix
follows that precedent rather than inventing one: `package.json` is excluded
from `hooks-built` the same way, and a dedicated `commonjs-marker` rule
attributes the family across all four roots it can appear in (both hooks roots
plus `plugins`/`extensions`) to the sources that actually emit it.

Deliberately a RULE, not an entry in tests/emitted-drift-ack.json. An ack is for
a one-off ripple and goes stale by design — the gate fails a stale ack precisely
so it cannot pre-clear the next change on that path. These markers are a
permanent part of the emitted tree from #2544 onward, so they need standing
attribution.

Verified by reproducing the CI failure locally with GSD_EMITTED_BASE: 3
provenance errors + 12 unattributed paths before, 35/35 green after.

* fix(#2544): route the #2717 hooks-surface marker helpers through commonjs-marker

#2717 landed a second copy of ensureCommonJsMarker/removeCommonJsMarkerIfGsdOwned
in src/runtime-hooks-surface.cts for the runtimes that stage .js hooks via
dedicated paths (cursor/windsurf/codex). That copy had drifted from this PR's
module on the two properties that matter:

  - ownership probe: `fs.existsSync` FOLLOWS symlinks and reports false for a
    DANGLING one, so a dangling package.json symlink classified as absent and
    the write went straight through it. Demonstrated: against the pre-fix copy,
    ensureCommonJsMarker() on a hooks/ dir holding a dangling package.json
    symlink returns true and creates {"type":"commonjs"} OUTSIDE that directory.
  - create: a plain writeFileSync leaves the classify->write window open, where
    commonjs-marker creates with flag:'wx' (O_EXCL).

Both helpers now delegate to src/commonjs-marker.cts, which is what this PR's
own docstring already claimed was the single place these rules are enforced.
Exported signatures are unchanged (still boolean), so bin/install.js and the
#2717 tests are unaffected.

The new subtest is the only coverage that fails if the duplicate is ever
reintroduced — the two implementations agree on every non-adversarial input, so
the existing suites pass against both.

* test(#2544): pin the stagedHooks gate on zcode, not windsurf

The Minor-5 coverage picked windsurf because hostBehaviors.skipSharedHooksInstall
kept it out of the shared hooks bundle, so GSD staged nothing into hooks/ and the
marker was correctly absent.

#2717 changed that premise: cursor/windsurf/codex now stage their .js hooks via
dedicated paths and get the marker beside those scripts. Measured on this tree,
windsurf stages 2 .js hooks and receives a marker — so the assertion was pinning
behaviour that is now wrong, not the gate it was written for.

ZCode is the durable choice: per #1821 it has hooksSurface:'none' AND no plugin
surface to spawn hooks, so GSD stages no .js there by either route (measured: 0
staged, no marker). The property under test is unchanged — a user-created hooks/
directory GSD never fills stays marker-free.

* test(#2544): use the shared cleanup helper in the migration test

Addresses the review's Major 1. The suppression's stated reason — "no helpers
import available" — was not correct: tests/helpers.cjs exports cleanup, and the
other test file added in this same PR imports it (tests/commonjs-marker.test.cjs).

The local reimplementation dropped two protections that are live on this repo's
windows-latest lane: the CWD guard (Windows cannot remove a directory that is the
current working directory) and the 20 x 250ms retry budget that absorbs the
deferred-scan handle Windows Defender holds on newly-written files.

Local function and suppression both removed; local/no-raw-rmsync-in-tests now
passes without one.

* test(#2544): expect hooks/package.json for the #2717 runtimes

The fresh-install contract table predates #2717, which stages cursor/windsurf/
codex .js hooks via dedicated paths and writes the CommonJS marker beside them.
All three therefore now receive hooks/package.json legitimately.

Measured on this tree: codex stages 3 .js hooks, cursor 6, windsurf 2 — each with
the marker; cline/copilot/trae/zcode stage none and get none, so their contracts
are unchanged.

* fix(#2544): gate the #2717 marker writes on having staged something

The three dedicated marker writers #2717 added ran unconditionally. Each one
mkdirs hooks/ up front and stages its scripts conditionally on the source
existing, so with an absent or empty hook source they created a directory,
filled it with nothing, and marked it as GSD's anyway.

That is the same write-into-someone-else's-territory this issue is about, and
installSharedHooksBundle already guards the identical case with `stagedHooks`.
The dedicated paths now carry the matching gate:

  - cursor / windsurf: `installedScripts.size > 0`
  - codex: a new `codexStagedHooks` flag. The enclosing guard only proves that
    hooks/dist EXISTS; it says nothing about whether any CODEX_HOOKS_TO_COPY
    entry landed.

Covered for cursor and windsurf by driving each writer against a src tree whose
hooks/ dir is empty. The codex leg is defensive and deliberately uncovered: its
trigger state needs a package tree where hooks/dist exists but holds none of the
allowlist, which is not constructible from a real checkout.

* test(#2544): scope the commonjs-marker sources per root

The rule declared one flat source list for every marker root, so
`extensions/package.json` was attributed to runtime-hooks-surface.cts (which
never writes there) and `.kimi/hooks/package.json` to install-engine.cts.

That is not merely untidy. emitted-diff.cjs accepts the FIRST satisfied source,
so a flat list containing bin/install.js let any change anywhere in that
13k-line file authorise marker drift for every root — the blanket escape hatch
this file's own agents-verbatim comment refuses for exactly the same reason.

Sources are now derived per root from ctx.rel. Note the rule ctx is
`{ rel, runtime }` and carries no `root`, so keying on ctx.root would have sent
every path down one branch silently.

* test(#2544): state precisely what the zcode assertion pins

The comment claimed the test pinned installSharedHooksBundle's `stagedHooks`
gate. It does not, and neither did the windsurf version it replaced: zcode
declares skipSharedHooksInstall, so the outer guard skips that helper entirely
and the gate is never evaluated. The test passes on the runtime exclusion.

What it does pin — the outcome a pre-existing, GSD-untouched hooks/ stays
marker-free — is still worth having, and is what the review asked for. The two
`staging zero hook scripts` tests are the ones that pin a real staged-nothing
gate. Comment corrected rather than left implying coverage that is not there.

33fd203ccd test(#2966): loop QA walk — drive real scenarios across all five loop steps (#2976)
* test(#2966): loop QA walk — drive real scenarios across all five loop steps

Adds a headless walk that carries accumulating project state across
discuss -> plan -> execute -> verify -> ship against one temp project,
layered over the existing tests/helpers.cjs runGsdTools substrate.

Findings carry severity. A violation breaks a stated contract and fails
the build; a smell is legal under today's implementation but structurally
questionable, is recorded, and never reddens CI. Without that split an
oracle set derived from current behavior can only ever confirm current
behavior -- the harness could not say "this works and is still wrong".

The end-to-end test asserts the walk produces at least one smell: a QA
harness that reports nothing on a first run against a real engine is far
more likely mis-specified than the engine is perfect. It deliberately does
not pin smell ids or counts, which would re-freeze current behavior.

First run against the real engine: 0 violations, 3 smell classes --
init returns agents_dir outside the project tree; smart-entry emits prose
unconditionally so routing cannot be asserted; state-snapshot reports a
missing STATE.md through a payload key with exit 0.

Also fixes tests/fixtures/index.cjs: createFixture with git:true and
planning:false staged nothing, so the commit failed with "nothing to
commit". That combination was unreachable until greenfield needed it.

Extends RULESET.TESTS.feedback-loop-convergence from estimation to the
loop itself. Design lock: docs/adr/2966-loop-qa-walk.md.

* test(#2966): wire fault injection, make perturbations discriminating

Independent review found tests/qa/mutations.cjs entirely unwired: 462
lines exercised only by their own unit tests, with no mutation hook in
the scenario DSL and no scenario applying one, while the module header
and the ADR described fault injection in the present tense. Dead code
documented as live.

Adds a `mutate` step field, three perturbation scenarios, and a wiring
detector: a self-test scenario whose expectations are known-false and
which MUST fail. The previous anti-vacuity check asserted only that the
walk produced a smell, which passes on well-known engine behavior
regardless of whether the harness wiring works.

First perturbation attempt produced zero signal -- progress does not
structurally parse ROADMAP.md, so a corrupted roadmap sailed through. A
perturbation that cannot fail is the same defect in a new costume.
Probes now target roadmap get-phase, and each mutated step runs a clean
baseline first so `mutationObserved` records whether the corruption
changed anything at all.

Also clears four review findings: classify() returned PROSE for exit-0
with empty stdout; `warnings` was structurally unpopulatable on the
success path (execFileSync discards it) and is now documented as
error-path-only; read-only-idempotence passed vacuously when asked to
check idempotence without the data to check it; the ADR miscounted the
oracles.

Discrimination matrix across 8 mutations x 6 commands: bom,
duplicate-phase-id and escaped-pipes are absorbed silently by every
probed surface, and progress / smart-entry / roadmap validate never
reacted to any mutation.

* test(#2966): add path-containment guard for scenario-supplied targets

Security review found scenario-supplied paths joined to the temp project
with no containment check. step.mutate.target and agent.write keys were
validated only as non-empty strings, so a target of ../../../../etc/hosts
reached fs.unlinkSync / fs.writeFileSync / fs.symlinkSync outside the
project. The symlink mutation was worst: it read the traversed file, wrote
a sibling copy, deleted the original and symlinked it back.

Not exploitable today -- all shipped scenarios target .planning/ROADMAP.md
and scenarios are repo-committed, not runtime input. Fixed anyway: it is a
live primitive any future scenario or copied helper can reach.

Adds tests/qa/paths.cjs with resolveWithin(): rejects absolute paths, NUL
bytes and empty input, normalizes separators unconditionally, and requires
containment by path segment so a sibling like <base>-evil is not treated as
inside. Non-existent targets resolve via nearest existing ancestor rather
than falling back to a lexical compare. Scenario load now rejects traversing
or absolute targets up front.

oracles.cjs previously carried its own copy of the containment logic; both
now share paths.cjs, since a duplicated containment check is exactly the
divergence class this repo calls out.

* test(#2966): complete trajectory corpus, report emission, boundary-aware oracle

Adds the remaining trajectories and drives all 11 mutations end-to-end.
20 scenarios, 72 steps, 0 violations, 25 smells.

Adds qa-report.json with per-step verdicts and a copy-pasteable repro
command, plus --keep / GSD_QA_KEEP=1 to preserve a failing tree. A repro
line for a tree that was not preserved is marked NOT RUNNABLE rather than
emitting a command pointing at a deleted directory.

monotonic-progress is now boundary-aware. Two scenarios had been trimmed
to stop the oracle complaining at a milestone rollover, which destroys the
signal the trajectory exists to produce. Evidence: counters legitimately
reset to zero at milestone complete, but the payload milestone_version
lags until a new ROADMAP.md is written. So the oracle now scopes by
milestone plus workstream, keeps a same-scope decrease as a violation, and
records a boundary crossing as a smell. Both scenarios walk the real
boundary again.

Standards review fixes: oracle findings now carry a structured subject so
tests assert on typed fields instead of substring-matching the free-form
detail string, resolveWithin throws a typed EPATHESCAPE error, and the
absolute-path predicate scenario.cjs had re-implemented now comes from
paths.cjs.

* test(#2966): fix silently-vacuous fixtures and guard the class

Every fixture carried its #2371 provenance comment BEFORE the frontmatter
block, and extractFrontmatter returns {} when anything precedes the opening
---. So every scenario reading status/phase/name was operating on an empty
object and reporting green. Nine fixtures repositioned; the comment stays,
it just moves below the closing ---.

Both UAT fixtures lacked a parser-recognized result block, so
evaluateUatPassed saw checks.length===0 and could never return passed:true.
The uat-fail-then-remediate scenario could not have proven a remediation.
Its expect block only inspected blockers, which is empty before AND after,
which is why the corpus never noticed. Both fixtures now carry real result
blocks and the scenario asserts passed and no_uat_artifacts on each side of
the flip.

The actual deliverable is the guard: a fixture-integrity block asserting
every fixture with a frontmatter shape parses to a non-empty object, that
every fixture carries its provenance marker, and that the two UAT fixtures
produce opposite verdicts through the real evaluateUatPassed. The first
guard written required --- at byte 0, which would never have fired on the
regression it exists to prevent; it was rewritten and proven by deliberately
re-breaking a fixture.

No engine defect here. no_uat_artifacts means no parsed check items, not no
UAT files, and it was reporting correctly on fixtures that had none.

* test(#2966): make the walk report — smell ratchet, baseline, CI job

The harness computed smells into a gitignored qa-report.json that nothing
read. In CI it surfaced nothing at all: violations failed the build, but the
half of the tool that says "this works and is still wrong" was inert. A QA
tool nobody hears is decoration.

Adds a ratchet on the same idiom this repo already uses three times over
(the regression-test-name allowlist, the emitted-drift acks, the size
baseline): a committed smell-baseline.json, per-PR acknowledgment fragments
under tests/qa/smell-acks/, and a ratchet script wired into CI.

The design invariant is preserved exactly. A smell still never fails a build
on its own merits. What fails is an UNACKNOWLEDGED NEW smell -- the absence
of a decision -- leaving an author two honest exits: fix it, or record a
fragment with a real reason. An empty reason is rejected. The baseline is
shrink-only, so a fixed smell must prune its entry. Violations remain
unacknowledgeable.

Fingerprints are composed only from stable fields (oracle id, scenario,
argv, subject discriminator) -- never temp paths, timestamps or counts.
Verified byte-identical across two runs in separate temp dirs; an unstable
fingerprint would have false-positived every CI run.

CI gains a qa-loop-walk job that runs the suite and the ratchet, uploads the
report with `if: always()` (it matters most when it failed), and renders a
summary a reviewer reads without downloading anything.

Also fixes the report runner invoking main() unconditionally on require, so
importing it double-ran every scenario and clobbered its own output.

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

* test(#2966): every smell terminates in a defect or a fixed detector

The baseline accepted a smell with a free-text reason. That is a mechanism
for designing smells in -- an allowlist nobody revisits. The harness is
brand new, so nothing it found is inherited legacy; every finding is a
FIRST finding. Each must now terminate in exactly one of two states:

  REAL           -> an assigned defect, entry carries the issue number
  FALSE POSITIVE -> the detector is wrong and gets fixed, never baselined

There is no third "accepted with a good explanation" state, so the ratchet
now requires a positive-integer `issue` on every entry. A reason may remain
as a human note but can never substitute. `--update` refuses to invent
issue numbers: a new smell is written with `issue: null` and a TODO, and
the next plain run rejects it, forcing triage rather than accumulation.

Working the 21 existing entries through that rule found 16 were my own
detectors being wrong:

value-hygiene (10) flagged $.agents_dir, a field whose entire contract is
to point at the install tree outside any project. Fixed with a leaf-key
allowlist of contractually-external fields, verified as the only such key
in the init payload. Genuinely unexpected out-of-project paths still smell.

monotonic-progress (6) fired on legitimate boundary crossings -- milestone
v1.0 to v2.0, workstream beta to alpha -- and on one payload carrying no
scope fields at all, where a change cannot even be known. Scope changes now
reset silently and scope-less observations are skipped. The same-scope
decrease remains a violation; that is the real invariant and is regression-
guarded.

The five survivors are real and now tracked: soft-error-exit-zero (#2980),
untyped-success (#2979). Baseline 25 -> 5.

* test(#2966): keep the ratchet out of the tarball, unpin the qa CI job

The remote matrix returned failed -- 3 unique failures, identical on
node22 and node24, both root causes in this branch's own diff.

The ratchet lives under scripts/, which ships in the npm tarball, and it
requires three modules under tests/, which does not. In a published
install it is MODULE_NOT_FOUND at load. This is exactly the class the
#2858 guard was added to catch, and it caught it. Fixed the way #2858
fixed the same shape for its own repo-only CI script: a targeted files[]
negation, so the ratchet stays in the repo for CI and out of the tarball.
Not solved by moving or inlining the required modules -- the ratchet must
keep using the same code the harness uses, or the two drift.

Verified both directions: the script is no longer in the pack list, and
build-hooks.js, fix-slash-commands.cjs and gen-capability-registry.cjs are
all still shipped. Over-negating there would have broken installs, since
bin/install.js requires them.

The qa-loop-walk job also carried CI_REBASE_BASE_SHA copied from a
neighbouring job without the paired GSD_EMITTED_BASE, which the #2854
invariant forbids by name: diverging them makes the differential compare a
tree against a baseline from a different commit. The job runs only the qa
suite and the ratchet and invokes no emitted-attribution test, so it needs
no rebase-pinned base at all -- the step was removed rather than paired.

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

* test(#2966): stop monotonic-progress going blind on scope-less payloads

The full remote suite caught a false NEGATIVE I introduced while fixing a
false positive. Silencing the boundary-crossing noise had made the oracle
skip ANY observation lacking milestone fields -- so a minimal payload like
{total_summaries: n} produced no violation at all, and the oracle stopped
catching the exact defect it exists to catch. For a QA tool that is
strictly worse than the noise it replaced.

Scope is only indeterminate when the two observations DISAGREE about
having it:

  both scoped, same scope, decrease -> VIOLATION
  both scoped, different scope      -> reset silently
  NEITHER scoped, decrease          -> VIOLATION   (the regression)
  mixed                             -> skip the comparison

Implementing the mixed case surfaced a second blind spot: advancing the
reference point on a skipped pair lets a scope-less observation sitting
between two same-scope ones mask a real decrease. Mixed now leaves the
reference untouched. All four branches carry explicit coverage; only one
did before, which is why this shipped.

The self-test that failed was right and the code was wrong, so the code
moved. Corpus behavior is unchanged: still 5 smells, 0 new, 0 stale, 0
violations.

9ac0dfad58 chore(#2929): generalize prompt-budget into the shared context-composer seam (#2958)
* test(#2929): capture prompt-budget parity corpus pre-refactor

Phase 2 of epic #1671 generalizes prompt-budget's trim ladder into a shared
context-composer seam. Its success condition is that review-prompt output does
not change, and the only authority on "did not change" is the behavior that
shipped before the refactor. Capture that behavior now, while it is still the
live implementation.

47 characterization cases, every `expected` value computed by executing the
current implementation rather than hand-authored — the independence
CONTRIBUTING.md "Fixture provenance (#2371)" asks for.

A corpus is only worth what it can detect, so this one was validated by
mutation rather than assumed. Five deliberate defects were injected and each
must be caught by at least one case:

  - the note reserve deducted unconditionally instead of only under pressure
  - the pressure test relaxed from `>` to `>=`
  - a no-op head-shrink still setting the shrunk flag
  - the per-plan floor dropped from the proportional share
  - drop order reversed

Two of those exposed real holes in the first cut of this corpus, and the cases
that close them exist because of it:

  - `>=` was caught by NOTHING. At exact cap the only trimmable fragment was a
    floored plan group, and the 1024-char floor absorbed the entire trim, so the
    mutation was byte-invisible. A3b/A3c put a droppable at exactly the cap,
    which makes the strict inequality observable as context kept vs omitted.

  - No case reached proportional-truncate at all — B6 and B7 both hard-failed
    the min-set pre-check first, leaving planTruncationPct at 0 across every
    case and the floor semantics entirely unexercised. Rebudgeted to 700 and
    1100 so the min-set fits and the truncate step is actually reached; they now
    record 40.20% and 48.80%.

The A4/A10 families sweep the pressure boundary from both sides, which is where
this function has regressed before: CONTEXT.md's
LEARNING.prompt-budget.boundary-gap records PR #3708 shipping two regressions
that only fired when the baseline sat inside the NOTE_RESERVE_TOKENS band,
because the suite paired a trivially-fitting budget with a trivially-overflowing
one and never sampled between them. A4 pins that nothing is trimmed from the cap
down to 81 tokens under it; A10 pins that pressure fires at +1. Together with
A3b/A3c they satisfy row (d) of RULESET.TESTS.boundary-coverage.fixtures.

Two facts the corpus establishes that the design notes had wrong:

  - "" and null sections are NOT distinguished. applyBudget uses truthy checks
    throughout, so an empty-string section is treated as absent: not rendered,
    not dropped, never recorded in `omitted`. B13b pins this while the ladder is
    actively trimming, where only the non-empty `research` is dropped.

  - Sizing matters. B12/B13 were first written at a budget where both hard-failed
    the min-set check and returned "", so comparing them compared two empty
    strings and proved nothing.

Committed as its own commit, ahead of the refactor, and regenerated against the
pre-refactor implementation, so the oracle is demonstrably independent of the
change it will adjudicate.

Refs #2929

* refactor(#2929): extract the context-composer seam from prompt-budget

Epic #1671 needs prompt-budget's budget-trimming logic for a second consumer —
per-runtime artifact emission — but it is walled inside the cross-AI review
pipeline. Lift it into a shared seam so later phases can call it, without
changing what the review pipeline emits.

ADR-1671 specifies the composer as "priority + binary-search cutoff to a
per-runtime budget". Read against the code it generalizes, that contract cannot
express the thing being generalized. applyBudget is not a cutoff: it is a fixed
five-step ladder in which each section carries its own shrink strategy, and only
three of its eight sections are ever dropped. PROJECT.md is head-shrunk to N
lines; plans are proportionally tail-truncated with a per-plan 1024-byte floor;
instructions and roadmap are never touched at all. A cutoff composer sorts by
priority and discards the tail — it has no way to say "shrink this one",
"truncate that one but never below 1 KB each", or "these three are the only
droppables, in this order". Building to the literal contract and routing
prompt-budget through it would have silently changed review-prompt output, which
is the one outcome this phase forbids.

So shrink strategies are the core abstraction here, and cutoff becomes one
strategy among them — the right one for per-runtime emission in Phases 3-4, not
for this ladder. That is an elaboration of the ADR's intent, not a departure
from it, and ADR-1671 is updated to say so.

Three decisions worth stating:

  - The composer DECIDES; the caller RENDERS. composeWithinBudget returns a plan
    of surviving fragments and never a string. assemblePrompt's rendering is
    prompt-shaped (`## Roadmap`, `### <file>`, the note in position two), and
    owning it in the composer would force emission to adopt prompt-shaped
    rendering. The split is what lets one seam serve both consumers.

  - The budget unit is INJECTED via `measure(text)`. prompt-budget passes its
    chars/4 estimator; emission will pass a byte counter, which ADR-1671 requires
    for emission caps. The existing code converts a token budget to a character
    budget with a hardcoded `* 4`; that assumption is now an explicit
    `charsPerUnit` inverse, which is precisely what a byte unit needs in order to
    reuse this.

  - The entry point is `composeWithinBudget`, not `applyBudget`. That name
    already exists twice — src/prompt-budget.cts and src/graphify.cts, the latter
    being an unrelated graph-edge budget. A third would make every symbol search
    in this repo ambiguous, and it already misresolves: preflight and impact
    queries for "applyBudget" return graphify's.

Behavior is unchanged and proven so: all 47 characterization cases reproduce
byte-identically, and the corpus is mutation-validated rather than merely green
(see the preceding commit). prompt-budget.cts drops from 436 to 343 lines and
from eighteen mutable accumulators to two, both inside a helper copied verbatim.

estimateTokens deliberately stays in prompt-budget and keeps its exact math:
src/phase-estimation.cts re-exports it as measureTokens, and CONTEXT.md pins
plan estimates and recorded actuals to that same scale, so moving or changing it
would silently break the calibration loop.

Refs #2929

* docs(#2929): document the context-composer seam and amend ADR-1671

Adds the INVENTORY row, the CONTEXT.md glossary entry (a PR gate for new
domain modules), and a mutation-matrix entry for the new module.

The ADR amendment is the substantive part. ADR-1671 specified the composer as
"priority + binary-search cutoff to a per-runtime budget". Implementing Phase 2
established that a cutoff alone cannot express the function the platform
generalizes, so the ADR now records shrink strategies as the core abstraction
with cutoff as one strategy among them, reserved for per-runtime emission in
Phases 3-4. Recording it in the ADR matters because Phases 3-6 are planned
against that contract and would otherwise be planned against a mechanism that
does not work.

The mutation-matrix entry is not bookkeeping. Stryker scores per module against
a named .cjs, so relocating the ladder out of prompt-budget.cjs would leave the
extracted code unmeasured while prompt-budget's own score floated free of the
logic it used to cover. context-composer gets its own entry at the same floor.

Refs #2929

* test(#2929): pin the effectiveBudget rounding mode in the parity corpus

An isolated correctness review found a real blind spot: mutating
`Math.floor` to `Math.round` in the effectiveBudget calculation failed ZERO of
the 47 corpus cases. Every (budget, safetyMarginPct) pair in the generator
happened to produce a whole number, so floor, round and ceil all agreed and the
rounding mode was entirely unpinned by a corpus whose whole job is to pin
observable behavior.

Three cases fix that by straddling the .5 boundary:

  A11  95 * 0.90  = 85.5   floor 85, round 86  -> the two disagree
  A12  97 * 0.90  = 87.3   floor and round agree; ceil (88) does not
  A13  93 * 0.85  = 79.05  same guard at a non-multiple-of-10 margin, so the
                           margin arithmetic is exercised and not just the budget

A11 alone catches the round mutation; all three catch ceil. Regenerated against
the pre-refactor implementation (`git show 9557f8552:src/prompt-budget.cts`), so
the expanded corpus keeps the independence property the original capture had.

The corpus is now mutation-validated against seven injected defects, every one
caught: unconditional note reserve, `>` relaxed to `>=`, no-op head-shrink
setting its flag, the truncate floor ignored, drop order reversed, and both
rounding-mode changes.

Refs #2929

* feat(#2929): flexReserve floors and the byte-stable isolate prefix

Two of issue #2929's "Done when" items were unimplemented rather than deferred,
and an isolated review flagged them alongside my own audit. Both are part of
ADR-1671's composer contract, so shipping the seam without them would have left
Phases 3-4 building against a contract that does not exist yet.

flexReserve is a per-fragment floor in measure units that every strategy must
respect, which is what makes it different from the pre-existing floorChars: that
one is a chars-denominated detail of proportional-truncate alone and is retained
unchanged. A floored fragment is never dropped, is never head-shrunk below its
floor, and raises its own proportional cap. A fragment already smaller than its
floor is untouchable outright. Metadata gains `floored`, listing the ids whose
floor actually prevented a trim — a guarantee no caller can observe is a
guarantee no test can hold you to.

isolate marks the byte-stable canonical prefix the ADR calls for: never trimmed,
never dropped, but still counted, because a prefix excluded from accounting
would silently under-count real context. Metadata gains `isolatePrefix` so a
caller can hash or assert on the exact bytes. Declaring an isolate fragment
after a non-isolate one throws: a prefix that is not at the front is not a
prefix, and accepting it would make the cross-runtime stability claim
meaningless.

Adds tests/context-composer.test.cjs for the exact new semantics and
tests/context-composer.property.test.cjs for the five invariants, including the
budget-monotonicity property the issue names explicitly. Both are registered in
the mutation matrix, since coverage does not migrate with relocated code.

prompt-budget uses neither feature, and its output is unchanged: all 50 corpus
cases still reproduce byte-identically.

Refs #2929

* chore(#2929): allowlist the prompt-budget parity suite

The parity corpus needs its own test file and that makes prompt-budget a
three-file module against a limit of two. The lint offers consolidation or an
allowlist entry with justification; the entry is the right call here.

Consolidation would mean folding the characterization suite into
prompt-budget.test.cjs, which is the one thing that should not happen to it. The
parity suite is a distinct concern with a distinct lifecycle: it is generated
rather than hand-written, it is named by scripts/mutation-matrix.cjs as its own
scoring target, and its failure means something categorically different from a
unit-test failure — not "this behavior is wrong" but "observable output moved".
Burying it inside a general unit file would obscure exactly that signal.

The allowlist is an identity ratchet, so this entry pins today's three exact
filenames: adding a fourth still fails, and dropping back to two requires
removing the entry.

Refs #2929

* fix(#2929): register the new module with two gates it was missing

The remote matrix caught three defects that no local check could, because the
local runner is blocked in this repo and these suites had therefore never
executed. Eight failures, identical on node22 and node24, so nothing
environment-shaped.

Two are the new-module ripple. A net-new src/*.cts lands in six places and this
change had reached four of them — .gitignore, INVENTORY, the manifest, and the
CONTEXT.md glossary — while missing the ESLint ignore list (tsc OUTPUTS must not
be linted; repo-invariants asserts linted-xor-ignored) and the mutation ratchet
baseline (a deliberate review-visible mirror of the matrix floors, which every
COVERED module must carry). Both are now registered, the ratchet at the same
floor of 66 the matrix declares.

The third was a test asserting an outcome it had made impossible. It set
budget:1 alongside a 400-char required fragment, so the group budget came out at
-99 and the proportional-truncate step was skipped entirely — the deliberate
"non-positive group budget is skipped, never clamped" rule inherited from the
original ladder. Nothing was trimmed, and the test then asserted a truncation.
Rebudgeted so the step actually runs, with the arithmetic written out in a
comment so the next reader does not have to re-derive why 120 rather than 80.

Fixing that surfaced a genuine bug in the composer. `floored` is documented as
recording fragments whose flexReserve prevented a trim that would otherwise have
happened, but the push sat in the else-branch of "content did not change", so it
only fired when nothing was trimmed at all. A fragment truncated to a
reserve-raised cap has also had a trim prevented — 40 characters' worth in the
test above — and was silently absent from the field that exists to make the
guarantee observable. The condition was already right; it was in the wrong
branch. Now recorded on both paths: a drop prevented outright, and a truncation
capped higher than the share alone would have allowed.

Parity is unaffected — prompt-budget never sets flexReserve, so the branch is
unreachable from every corpus path, and all 50 cases still match.

4f6935e29b fix(#2717): write CommonJS marker for cursor/windsurf/codex staged .js hooks (#2846)
* test(#2717): CommonJS marker for cursor/windsurf/codex staged .js hooks

Cursor/windsurf (skipSharedHooksInstall) and codex (!isCodex gate) stage .js
hook scripts via dedicated paths that bypass installSharedHooksBundle — the
only writer of the {"type":"commonjs"} marker. Under a config root declaring
{"type":"module"}, Node loaded those scripts as ESM and every require()
failed with 'require is not defined', silently disabling the runtime's hooks.

Adds regression tests (RED first, fix lands next commit):
- parametrized cursor/windsurf/codex install asserts hooks/package.json exists
  with exactly GSD's marker content;
- end-to-end: a cursor require()-using hook loads under a planted ESM-typed
  config root without the require-is-not-defined error;
- the ensureCommonJsMarker / removeCommonJsMarkerIfGsdOwned contract: GSD
  markers are removed on uninstall, user-authored package.json is never touched.

* fix(#2717): write CommonJS marker for cursor/windsurf/codex staged .js hooks

The {"type":"commonjs"} marker lived only inside installSharedHooksBundle,
which cursor/windsurf (skipSharedHooksInstall) and codex (!isCodex gate) never
reach. Their .js hooks are staged by dedicated paths, so under a config root
declaring {"type":"module"} Node loaded them as ESM and every require()
failed with 'require is not defined', silently disabling those runtimes' hooks.

Decouple the marker write into a shared helper so any code path that stages
.js hooks can ensure it lands in the SAME directory as the scripts:

- src/runtime-hooks-surface.cts: add ensureCommonJsMarker(dir) +
  removeCommonJsMarkerIfGsdOwned(dir) (byte-identical content to
  installSharedHooksBundle's marker; preserves a user-authored package.json on
  both write and uninstall). Call ensureCommonJsMarker(hooksDir) from
  writeCursorHooksJson + writeWindsurfHooksJson; call
  removeCommonJsMarkerIfGsdOwned on their matching remove paths. Export both.
- bin/install.js: call hooksSurface.ensureCommonJsMarker after the codex hook
  copy; call hooksSurface.removeCommonJsMarkerIfGsdOwned in the generic
  hooks-removal loop (safe no-op where no marker exists).

No change to which runtimes receive the shared bundle, the !isCodex gate,
skipSharedHooksInstall, or kimi/kimi-code/cline/copilot/trae/zcode (all
unchanged — audit in the diagnosis). RED @ dbb7d2bb (6 failures: 3 missing
markers + the ESM require error + missing helpers); GREEN pending.

* docs(#2717): changeset fragment (pr:0, backfilled post-PR)

* chore(#2717): regen codex/cursor/windsurf install-tree fixtures + attribution ack

The fix adds hooks/package.json to those three runtimes' install trees (the
new CommonJS marker), so the golden install-tree fixtures gain one path each
(regenerated via npm run gen:install-tree). emitted-attribution (ADR-2719)
flags the 3 emitted hooks/package.json paths under the hooks-built rule;
acknowledge them. Also drops 5 spent ack entries left by now-merged PRs
(#2694 code-review.md/code-review-fix.md, #2695 worker/registry, #2794
review.md) — they are stale on this branch (base already carries them).

* fix(#2717): codex ESM-root behavioral test + hooks-built provenance for package.json

Two review-driven follow-ups on the #2717 fix:
- Adversarial review noted the ESM-root behavioral test covered only cursor;
  refactor it into a helper and add a codex case (the !isCodex-gated path most
  likely to regress, whose marker write lives in bin/install.js). gsd-check-update.js
  require()s at module load, so it surfaces the ESM failure immediately.
- emitted-provenance flagged hooks/package.json as 'attributed source does not
  exist' — the marker is code-derived (a fixed literal emitted by
  ensureCommonJsMarker at install time), not built from a tracked source. Route
  the hooks-built rule's sources/transforms for package.json to the surface
  source file, mirroring the existing .cmd-shim sub-family.

* chore(#2717): drop now-redundant hooks/package.json attribution ack

The hooks-built provenance routing (prior commit) now self-attributes the
emitted hooks/package.json to src/runtime-hooks-surface.cts, which IS in this
diff — so the attribution is self-explaining and the emitted-drift-ack entry
became stale. Delete the (now-empty) ack file per ADR-2719's empty-file rule.

Three fixes required to delete the golden fixtures without breaking CI:

- scripts/ci-test-scope.cjs: remove tests/golden-install-parity.test.cjs
  from the three rules that named it. #2759's missingRuleTestFiles guard
  hard-throws at module load if a rule names a test file absent from
  disk, which would break the changes job on every PR the moment the
  fixture-deletion commit landed.

- tests/helpers/emitted-provenance.cjs: loadManifests() read the
  committed golden fixture directory. With that directory deleted at
  every future ref, this would throw at module load forever, taking
  the Phase 2 totality guard down with it. Rebuilt from real installer
  spawns (MANIFEST_FAMILIES + runMinimalInstall + buildParityManifest),
  the same shape emitted-runtime.cjs's currentManifests() already uses.

- tests/emitted-attribution.test.cjs / tests/helpers/emitted-runtime.cjs:
  the real-tree test's baseline acquisition swaps from
  baselineManifestsAtRef(base) (git show at a ref that no longer carries
  fixtures) to resolveBaseline()'s documented precedence: env, then the
  on-disk cache, then an in-job build. The build fallback
  (buildBaselineAtRef, new) checks out base into a throwaway git
  worktree and runs the new scripts/gen-emitted-baseline.cjs there --
  no npm ci needed, since bin/install.js and the test helper shells are
  Node-builtins-only. That script also publishes the baseline artifact
  from CI's push-to-next job (wired in a follow-up commit).

* refactor(#2724): retire the merge-driver bridge and per-file size baselines

The Phase 1 bridge (#2721) is retired now that the artifacts it guarded
are deleted: scripts/git-merge-regen-driver.cjs, its test, and the
'setup:merge-driver' npm script are removed, and the .gitattributes
merge=gsd-regen/linguist-generated block for the three deleted-path
globs is dropped. tests/fixtures/install-tree/*.json keeps its normal
merge behavior, unchanged (ADR-2719 section 7).

scripts/update-size-baseline.cjs and its test are removed: their sole
purpose was regenerating tests/workflow-size-baseline.json and
tests/agent-size-baseline.json, both deleted. The 'size:baseline' npm
script and its step in 'regen:derived' go with it. The per-file
baseline describe blocks in tests/workflow-size-budget.test.cjs and
tests/agent-size-budget.test.cjs are removed for the same reason; the
independent loose-tier hard caps are untouched. The differential
attribution check's size ratchet (tests/emitted-diff.cjs, already
shipped in #2723) is the replacement anti-creep mechanism.

'npm run gen:golden' is replaced by 'npm run gen:install-tree', which
keeps regenerating tests/fixtures/install-tree/*.json (the one artifact
family ADR-2719 section 7 keeps committed); tests/golden-install-tree.test.cjs's
error messages point at the new command name.

tests/golden-parity-single-source.test.cjs's anti-divergence guard
(#2266) is retargeted from the two deleted golden-parity consumers to
their two replacements (tests/helpers/emitted-runtime.cjs and
tests/helpers/emitted-provenance.cjs), which import buildParityManifest
the same way — the divergence risk the guard exists for is unchanged.

Also wires CI: a new publish-emitted-baseline job runs
scripts/gen-emitted-baseline.cjs after a push to next and caches the
result keyed on the sha; the test and test-full jobs restore that cache
on pull_request events, keyed on the PR's base sha, and export
GSD_EMITTED_BASELINE for tests/emitted-attribution.test.cjs's real-tree
test to pick up.

* docs(#2724): flip ADR-2719 to Accepted and update contributor docs

Status: Proposed -> Accepted. Regenerated docs/adr/README.md index.

CONTRIBUTING.md, docs/TESTING-SUITES.md, and CONTEXT.md (RULESET.
EMITTED_ATTRIBUTION, RULESET.WORKFLOW_SIZE_BUDGET, RULESET.
AGENT_SIZE_BUDGET, and the Emitted Artifact Provenance glossary entry)
no longer point at the deleted golden-install-parity fixtures, size
baselines, gen:golden, UPDATE_GOLDEN, or the setup:merge-driver /
git-merge-regen-driver.cjs bridge. Editing shipped content now
requires zero manual fixture regeneration, documented against the
differential attribution check instead of the deleted commands.

* docs(#2724): add changeset for removed golden-parity commands

* fix(#2724): drop stale scripts/update-size-baseline.cjs glossary ref

check-glossary-refs.cjs verifies every backtick-wrapped scripts/*.cjs
token in CONTEXT.md resolves to a real file. The RULESET.
EMITTED_ATTRIBUTION rewrite named the deleted script inside backticks,
which the checker reads as a live reference, not historical prose.

* test(#2724): retarget ci-test-scope tests off the deleted golden test

tests/ci-test-scope.test.cjs asserted specific RULES entries select
tests/golden-install-parity.test.cjs, and that every rule selecting it
also selects both emitted gates. Both premises broke when the golden
test was deleted (#2724): the deleted filename never re-appears in
targeted_tests, and there was no longer a third file for the gates to
travel alongside. Retargeted the two selection describe blocks to
assert tests/emitted-provenance.test.cjs directly (the drift guard the
golden gate's rules were retargeted to), and simplified the third block
to assert the two emitted gates always travel together, without
reference to the golden filename.

* docs(#2724): repoint two contributor how-to guides at the differential check

Both guides told contributors to regenerate a baseline against
tests/golden-install-parity.test.cjs, which #2724 deletes. Repointed
at the differential attribution check (tests/emitted-attribution.test.cjs,
ADR-2719), which needs no manual regeneration step.

* fix(#2724): repair phase6-capstone-conformance's deleted-baseline read

An independent orthogonal review caught a real regression this branch
introduced into a test file the branch's diff never touched:
tests/phase6-capstone-conformance.test.cjs read
tests/workflow-size-baseline.json (deleted earlier in this branch) with
no fallback, so the whole suite would throw ENOENT the moment this
branch landed. The test's actual intent — prove the host-loop workflow
files are real, tracked, non-empty docs — is preserved by asserting the
live byte count via the same shared counter (scripts/workflow-size.cjs)
the size guards already use, instead of a committed snapshot.

Also, from the same review: a stale doc comment in
scripts/workflow-size.cjs still named the deleted
scripts/update-size-baseline.cjs as a consumer, and
buildBaselineAtRef's cleanup in tests/helpers/emitted-runtime.cjs left
two fs.rmSync calls unguarded against masking the primary result/error,
inconsistent with the try/catch already wrapping the git cleanup beside
them. Both fixed. A doc comment was added to baselineFamilyNamesAtRef
explaining why it (and its siblings) are kept despite having no
production caller post-cutover — they still answer real questions
about refs that predate the cutover.

* fix(#2724): repair three real regressions found by remote verification

1. tests/emitted-provenance.test.cjs's two hostile-input tests
   (non-object manifest, unreadable fixture) drove loadManifests(tmp)
   and monkeypatched fs.readFileSync, both premised on the deleted
   fixture-directory read this branch already replaced with real
   installer spawns -- the negative assertions silently stopped firing.
   loadManifests() now accepts injected {families, install, build,
   clean} (defaulting to production values), giving the tests a real
   seam to drive a bad build result and a build failure through the
   ACTUAL loader instead of a reimplementation, and added coverage that
   clean() still runs on both paths.

2. .github/workflows/test.yml's two 'Export GSD_EMITTED_BASELINE'
   steps hardcoded shell: bash, which is wrong on windows-latest (native
   pwsh) and on test-full's macos-latest legs (native zsh per that job's
   own matrix) -- the repo's H1 shell policy (tests/policy-shell-pinning
   .test.cjs) caught it. Replaced the inline bash script with
   scripts/ci-export-emitted-baseline-env.cjs, a plain Node script: a
   bare 'node <path>' command line has no shell-specific syntax, so it
   runs correctly under bash, zsh, and pwsh without a shell override.

tests/phase6-capstone-conformance.test.cjs's deleted-baseline read
(caught by the same remote run, at a commit prior to this one) was
already fixed in d0c3b1242 and is not touched here; verified still
passing after these changes.

* fix(#2724): revive ADR-1610's new-file size cap inside the differential

An isolated review caught a real regression: deleting
tests/workflow-size-baseline.json silently dropped NEW_FILE_CAP
(ADR-1610 Decision point 3, the Codex project_doc_max_bytes anchor)
with no successor. tests/helpers/emitted-diff.cjs's size ratchet
already 'continue's past any file absent from sizeBaseline -- exactly
the files this cap exists to bound -- so a brand-new workflow file
sized 32,769-40,960 bytes passed CI clean and shipped, then risked
silent truncation at the Codex anchor at runtime. ADR-1610 is Accepted
and never referenced anywhere in this branch.

Fix: NEW_FILE_CAP=32768 revived inside emitted-diff.cjs's own
size-ratchet loop, keyed off the SAME hasOwnProperty(sizeBaseline,
name) signal the growth check already computes -- 'new' is exactly
'present in sizeCurrent, absent from sizeBaseline'. Not ack-able,
matching the tier hard caps it sits beside: the fix is extraction, not
an acknowledgment entry. Documented, disclosed narrowing: the pure
differential module cannot see XL_WORKFLOWS/LARGE_WORKFLOWS tiering
(tests/workflow-size-budget.test.cjs's classification), so a
legitimately large new file must extract rather than tier in, one
release earlier than an existing file would need to. ADR-1610 itself is
left unamended -- this restores its decision rather than re-litigating
it.

Also fixes a stale comment plus a redundant real 19-installer-spawn
assertion left over from the pre-injection-seam version of
tests/emitted-provenance.test.cjs's build-failure test, and annotates
3 of 4 stale golden-fixture citations in
docs/reference/host-integration-capability-matrix.md as superseded
(the 4th is an accurate historical PR narrative, left alone).

* fix(#2724): repair three red CI defects on the golden-fixture cutover

Windows-only provenance false attribution (defect A): the `hooks-built`
provenance rule attributed `hooks/<name>.cmd` to itself. Those shims are
Windows-only installer output (ensureCodexHooksJsonSessionStart /
ensureCodexHooksJsonEvent, both in src/runtime-hooks-surface.cts) wrapping
the same-named `.js` hook — no `.cmd` file is ever tracked in the repo, so
the self-attribution resolved to a path that exists on no platform. Only
windows-latest ever emits the key, so this only failed there. Fixed by
special-casing `.cmd` inside the SAME `hooks-built` rule (not a dedicated
rule) — a dedicated rule would match zero paths, and therefore report as a
dead rule, on every non-Windows lane of the same totality guard. `sources`
already supported per-match functions; `transforms` is extended to support
the same shape so the attribution can vary by match within one rule.

Baseline bootstrap was structurally impossible (defect B): `buildBaselineAtRef`
ran `scripts/gen-emitted-baseline.cjs` from INSIDE the base-ref worktree, but
that script is new in this PR and therefore absent at any base ref that
predates it — every call failed closed with "Cannot find module". Fixed by
running the PR checkout's own generator against the worktree via a new `--dir`
parameter, decoupling "which copy of the script runs" from "which tree it
measures" (`currentManifests`/`currentSizes` gained a `repoRoot` override,
threaded down to `runMinimalInstall`'s new `installScript` override). This is
not just a bootstrap fix: a differential needs ONE measurement schema applied
to both sides, or the two stop being comparable the moment that schema
evolves — running each side's own copy would silently reintroduce that risk.
Verified locally end-to-end against real origin/next: resolves a valid
{version, sha, manifests, sizes} artifact with the correct sha and no leaked
worktree.

Changeset placeholder (defect C): `pr: 0` -> `pr: 2767`, which is what let
docs-lint evaluate the fragment for the first time; it already passes
(docs/TESTING-SUITES.md and friends already document the removed scripts).

Also fixed while in this file: an eslint no-unused-vars warning surfaced by
the changed lint run (unused `cleanup` import in
tests/emitted-provenance.test.cjs).

Added regression coverage for both A and B: a cross-platform spot-check that
drives the real hooks-built rule against `.cmd` keys directly (not through a
real Windows install), and a real-tree test that drives buildBaselineAtRef
against a base ref verified (via git cat-file) to lack the generator, both
skipping honestly rather than false-passing when their precondition does not
hold.

* fix(#2724): repair false .cmd byte-provenance and a permanently-skipping regression test

Two isolated-review findings on PR #2767:

- `hooks-built`'s `.cmd` branch attributed the Windows shim's bytes to the
  wrapped `hooks/<name>.js` script, asserting a byte-provenance link that
  does not exist — traced against buildCodexHookWindowsShimIR
  (src/runtime-hooks-surface.cts), only the script's NAME (a literal in that
  same file) flows into the .cmd bytes, never its content. Point `sources`
  at HOOKS_WINDOWS_SHIM_SRC instead, matching the code-derived convention
  used elsewhere in the table. Since `sources` is checked before
  `transforms` in the differential, the wrong mapping silently excused any
  .cmd byte movement caused by editing the wrapped .js file.

- The `buildBaselineAtRef` regression test skipped unless a resolvable base
  ref still lacked scripts/gen-emitted-baseline.cjs — true only until this
  PR merges, after which every base ref carries the file and the test skips
  forever with zero ongoing coverage. Rebuilt hermetically: synthesize the
  missing-generator condition in-place via git plumbing (a throwaway commit,
  child of HEAD, with just that one file removed from a scratch index),
  never touching the real working tree, HEAD, or index, and never depending
  on ambient history or remotes.

* fix(#2724): tolerate the remote runner's dubious-ownership git mount in the emitted baseline path

The runner container mounts the repo at a path owned by a different uid than
the process running the suite, so git's dubious-ownership protection refuses
every git operation there. GitHub Actions never hits this because
actions/checkout registers the workspace as safe automatically; this
runner's container does not.

buildBaselineAtRef is the production build-fallback the sole remaining
emitted gate depends on (resolveBaseline's in-job-build leg), not just a
test helper, so the fix is in the shared git() wrapper (emitted-runtime.cjs)
that every caller — resolveChangedPaths, resolveBase, buildBaselineAtRef's
worktree add/remove/prune, and the hermetic regression test added in the
prior commit — funnels through, plus gen-emitted-baseline.cjs's own
rev-parse (now reusing that same wrapper instead of a second execFileSync,
so the fix has one source of truth). Each call declares -c
safe.directory=<the exact directory it already operates on>, never the *
wildcard.

Audited every other helper on this surface (emitted-diff.cjs,
emitted-baseline.cjs, install-shared.cjs) for the same gap: none of them
shell out to git at all.

60bc6ddd6e fix(#2568): commit the debug session doc on the manager-driven terminal path (#2731)
* test(#2568): failing-first contract for the debug manager's doc commit

agents/gsd-debug-session-manager.md contains zero occurrences of 'commit', so on
the manager-driven path — the normal /gsd-debug flow — nothing consults
commit_docs and session docs are left untracked. The step exists only in
gsd-debugger.md, which does not reach the end of a multi-cycle session.

Two layers. The spec placement is asserted against the shipped agent text because
that text is what the orchestrator executes; the commit_docs gate the fix relies
on is exercised behaviorally through the CLI in temp git projects, because 'the
CLI no-ops when disabled' is the assumption that makes calling it unconditionally
correct — asserting it in prose would be assuming the load-bearing part.

The most important case is the negative: CONTINUE_REQUIRED is non-terminal and
must NOT commit. A fix that satisfied the positive cases by committing
unconditionally would strand a half-finished session looking done, which is worse
than the bug.

RED expected on the five spec assertions; the three CLI gate tests pin existing
behavior and pass both sides.

* fix(#2568): commit the debug session doc on the manager-driven terminal path

agents/gsd-debug-session-manager.md contained zero occurrences of "commit", so on
the normal /gsd-debug flow nothing ever consulted commit_docs and session docs
were left untracked — reproduced by the reporter across three consecutive real
sessions.

An obligation left behind during a responsibility move. gsd-debugger.md commits
the doc at :1214, but that runs only when the debugger carries a fix to completion
inside a single spawn. The multi-cycle manager took over checkpointing, fix
application, archival to resolved/, and the terminal summary — every step that
finishes a session — without the commit step. The debugger's copy still exists and
still works on its own path, so "is this handled anywhere" answered yes.

The manager now commits before both terminal shapes, and explicitly NOT on
CONTINUE_REQUIRED. That exclusion is the load-bearing part: the manager's own
contract already forbids fabricating a terminal summary on that path, and
committing there would be the same lie in git form — a half-finished session
stranded looking done. CHECKPOINT REACHED likewise does not commit.

Two facts kept the fix small. The manager already carries the gsd_run preamble
(:96, used at :97 for resolve-model), so no new plumbing. And cmdCommit
(src/commands.cts:809-814) already gates on commit_docs and returns
skipped_commit_docs_false when disabled — so the agent calls it unconditionally
and correctness follows from the CLI rather than from a second copy of the config
check that could drift. Calling git commit directly was rejected for exactly that
reason: it would bypass a user's explicit commit_docs:false.

In-session fix code is staged by specific file, never git add -A, which would
sweep unrelated working-tree changes into a debug commit.

Body-only edit — frontmatter untouched, so the research-profiles/AGENTS.md ripple
does not apply. gsd-debugger.md's own commit step is preserved; the single-spawn
path still ends there, and a double commit is harmless since the second finds
nothing to stage.

Fixes #2568

* fix(#2568): bind the commit paths, define gsd_run in-block, and make the fix commit idempotent

Three defects in my own first cut, all found by the isolated adversarial pass.

1. BLOCKER — {debug_dir} was a dangling substitution. I copied it verbatim from
   the issue's suggested patch without checking scope. It is a real variable in
   gsd-core/workflows/debug.md, where the ORCHESTRATOR receives it from init JSON
   and uses it to build debug_file_path — but this agent never receives it:
   <session_parameters> declares only slug, debug_file_path, symptoms_prefilled,
   tdd_mode, goal and specialist_dispatch_enabled. An unbound token makes --files
   resolve to a nonexistent path; cmdCommit skips missing explicit files, staging
   stays empty, and the doc silently never commits — reproducing #2568 through a
   different broken path. Same class as #2684's dangling placeholders. Now spelled
   literally as .planning/debug/resolved/{slug}.md, matching gsd-debugger.md:1214
   and this file's own prose.

2. MAJOR — gsd_run was undefined in the commit block's shell. Shell state does not
   persist across tool invocations, and the Step 2 preamble is ~230 lines and an
   entire spawn-and-loop earlier. gsd-debugger.md redeclares the full preamble
   immediately before each of its own call sites; the commit block now does the
   same, byte-identical to this file's existing definition.

3. MAJOR — the in-session fix commit was not idempotent. gsd-debugger.md's
   archive_session already commits the fix on the confirmed-checkpoint path, which
   is the standard find_and_fix flow, so `git add X && git commit` would hit an
   empty diff, exit non-zero, and abort the step before the summary was returned.
   Guarded with `git diff --cached --quiet || git commit`. The doc-commit half was
   already safe — query commit treats an empty diff as nothing_to_commit and exits
   0 — and that asymmetry is now stated rather than assumed.

Three tests added for exactly these, since the reviewer correctly noted the suite
would have caught none of them: every token substituted into a commit command must
be a declared session parameter; the preamble must sit in the same block as the
call with no step boundary between; and the fix commit must carry the staged-content
guard.

* fix(#2568): keep the single canonical gsd_run preamble

The previous commit added a second preamble to the commit block, on the isolated
review's theory that shell state does not persist across tool invocations. That
theory is reasonable in general and wrong for this corpus: the repo enforces
"each agent .md using gsd_run contains exactly ONE canonical preamble, before the
first gsd_run call". Adding a second broke that invariant and five suites with
it — the B-agents preamble check, runtime-launcher-parity, and three slash-
namespace guards.

The single Step 2 preamble already precedes the commit call, so coverage was
never actually missing. Reverted to one, and the test now asserts the real
property — exactly one preamble, positioned before the call that needs it —
rather than the locality I had wrongly encoded.

Recorded because the direction of the mistake matters: the review was right that
the question needed asking and wrong about the answer, and I shipped the wrong
answer without checking the invariant that already governs it.

e48eb44003 fix(#1856): give the executor-worktree refusal a handoff instead of a dead end (#2727)
* test(#1856): failing-first contract for the orchestrator cwd-drift guard handoff

The #48 guard correctly refuses to execute waves from an agent worktree, but the
refusal is a dead end: that worktree can hold committed fixes AND uncommitted
work, and "re-run from the orchestrator's own worktree" silently means
abandoning them. The reporter was left choosing between continuing from a
blocked worktree and losing the work.

The guard is shell embedded in execute-phase.md, so these tests extract the
block by a stable marker and EXECUTE it against real git fixtures — the shipped
text is the runtime contract. Covers the stranded-commit and dirty-tree report,
the integration commands, both agent- namespaces, commit-count boundaries 0/1/2,
and the constraints the guard's own comment records: it must NOT fire on an
ordinary branch, on 'agentic-refactor', or on a legitimate feature worktree under
.claude/worktrees/, and must degrade cleanly with no resolvable base or a
detached HEAD.

RED expected: the marker does not exist, so extraction fails and every case errors.

* fix(#1856): give the executor-worktree refusal a handoff instead of a dead end

The #48 cwd-drift guard correctly refuses to execute waves from an agent
worktree — its comment records why ("this is how a wrong-base merge nearly
shipped ~1000 files"), and that refusal is untouched here. The defect is that it
was a dead end.

At the moment it fires, the worktree can hold committed product work, uncommitted
product and planning changes, and the live gap-planning context. Telling the user
to "re-run from the orchestrator's own worktree" silently means abandoning all of
it, because the orchestrator worktree cannot see commits that live only on the
agent branch. The reporter was left choosing between continuing from a blocked
worktree and losing five commits plus uncommitted work.

The refusal now reports what is actually stranded — the commit count and log
against the resolved base, and the uncommitted files — followed by the concrete
integration sequence (commit here, switch to an orchestrator-safe checkout,
merge or cherry-pick, re-run) and a verify command. Nothing is claimed that is
not there: a clean worktree with no commits ahead prints the plain refusal with
no empty sections.

Every added command is diagnostic and `|| true`-guarded, so a failure degrades to
the original refusal rather than crashing before the message prints. Verified: an
unresolvable base still refuses cleanly.

Deliberately NOT done: auto-merging or auto-cherry-picking the agent branch. That
is precisely the operation #48 exists to stop the orchestrator performing from a
drifted cwd, at the moment it has least confidence about which tree is which.
Reporting beats acting here.

The guard block carries a `gsd:guard=orchestrator-cwd-drift` marker so the new
contract test can extract and EXECUTE the shipped shell against real git
fixtures rather than asserting on its characters.

Fixes #1856

* fix(#1856): report true counts, add the changeset, and document the seam

Review findings, all from the isolated adversarial pass:

- The dirty-file list was capped at 20 with no indication, so a worktree with 27
  uncommitted files reported 20 — under-informing the user about exactly what is
  stranded, which is the entire point of this change. Both lists now count BEFORE
  truncating and print "… and N more". Verified with 25 commits / 27 dirty files.
- The has-commits condition was written out twice and could drift on a future
  edit. Collapsed to a single _WT_HAS_COMMITS flag.
- The changeset fragment existed but was untracked, so it was in neither commit
  on this branch and the PR gate would have failed against real history.
- CONTEXT.md:122 documents this exact seam ("the orchestrator runs a cwd-drift
  guard at execute_waves entry…") and was not extended. Now records the handoff
  report, that the refusal condition and exit code are unchanged, and that every
  added command is diagnostic and || true-guarded.

Verified NOT a defect, correcting the review's premise: the guard block does break
when its line endings are CRLF, but .gitattributes:2 is `* text=auto eol=lf`,
which OVERRIDES core.autocrlf and forces LF on checkout on every platform
including Windows — so the shipped file is LF there too, and the installer copies
it through Node without translating endings. The reproduction (mine and the
reviewer's) required injecting CRLF by hand. It is also not fixable from inside
the script: a \r breaks the shell parse at the block's first line, before any
#1856 code runs. Neither introduced nor amplified by this change.

Also noted and left as-is by design: the review flagged that #1856's "offer an
explicit recovery option" could be read as requiring an interactive/automated
integration rather than printed instructions. Deliberate — see the commit that
added the block: auto-merging is the exact operation #48 exists to prevent the
orchestrator performing from a drifted cwd. Called out in the PR body for a

1c93df04db fix(#2711): propagate the #2517 omit-on-inherit rule to all 15 unguarded workflows (#2713)
* test(#2711): derive the omit-rule guarded set from the corpus instead of a hand list

The GUARDED array was a Goodhart metric: it reported green across 15
non-compliant workflows for no better reason than that nobody had added them to
it. The guard now derives its set — every workflow emitting a model="{…}"
dispatch site must state the omit-on-inherit/empty rule — and asserts the
derivation is non-empty so a broken scan fails rather than passes.

Rule detection stays a PROPERTY check, not a template match: plan-phase.md and
execute-phase.md state it in different words and both are correct.

RED expected on 15 workflows: audit-milestone, code-review, code-review-fix,
debug, discuss-phase-assumptions, docs-update, map-codebase, new-milestone,
new-project, quick, secure-phase, ui-phase, ui-review, validate-phase,
verify-work.

* fix(#2711): propagate the #2517 omit-on-inherit rule to all 15 unguarded workflows

15 of the 19 model=-dispatching workflows carried no omit-on-inherit/empty
guidance — 43 unguarded dispatch sites. Each would emit model="" whenever the
bound *_model resolved empty, which is the DEFAULT state on non-Claude runtimes:
the installer writes resolve_model_ids:"omit" into ~/.gsd/defaults.json for every
one of them (references/model-profiles.md:101), and resolveModelInternal returns
"" for that case (src/model-resolver.cts:383-386) and "inherit" for opus-tier
agents and the inherit profile (:395). Both 404 on runtimes without native tier
aliases — the failure #2517 documented and fixed in one file.

Each file now carries a `<!-- #2517 model-omit-on-inherit -->` blockquote naming
its own bound placeholders and linking the canonical statement in
references/model-profile-resolution.md, mirroring the `<!-- #2508
runtime-aware-dispatch -->` block already present in all 15. The rule text lives
in the reference; the workflows carry a pointer plus the one-line instruction, so
the next revision edits one file rather than fifteen.

plan-phase.md and execute-phase.md are deliberately untouched — they already
state the rule in their own wording, and the guard checks the property rather
than a template string.

No dispatch site is edited and no placeholder renamed: the #2684 binding guard
reports the same 19 files / 60 placeholders / 0 findings before and after, which
is the independence proof that this change is additive prose only. There is no
Hyrum's-Law routing change to disclose.

Placement is span-aware. An initial pass anchored to the #2508 marker, but in six
files that marker sits INSIDE the Agent(prompt="…") string, so the new paragraph's
literal model= landed in a dispatch call span and tripped the #2284 fail-closed
Hermes projection guard (bin/install.js:3704), refusing the install. Blocks are
now anchored before the opening Agent( of the span owning the first dispatch, and
verified to fall inside no span. gen:golden exits 0 across all 19 runtimes.

Fixes #2711

* fix(#2711): cite the issue number in the changeset body and tidy block placement

Review findings from the two orthogonal passes:

- The changeset body ended (#0). Repo convention across every prior fragment
  (e.g. #2617/#2693, #2608, #2605) is that the trailing (#NNN) is the ISSUE
  number, known at authoring time; only the frontmatter pr: field carries the 0
  placeholder pending backfill. (#0) would have rendered a dead link in the
  published release notes.
- new-milestone.md glued the inserted block directly under the preceding
  paragraph with no blank line, inconsistent with the other 14 insertions.
- The derived-guard non-vacuity floor was >=17 against an actual derived count
  of 19, tolerating a silent two-file regression. Tightened to >=19.

* fix(#2711): reword the omit block so it survives Hermes projection, and exempt quick.md by size

The first block wording regressed two suites on the full matrix (4 failures on
both linux-node22 and linux-node24). gen:golden passing was not sufficient
evidence — it exercises the installer's own fail-closed guard, which is
narrower than the dedicated tests.

1. tests/fix-2284-hermes-agent-delegate-task-projection.test.cjs asserts that
   the INSTALLED code-review-fix.md contains no `model=` anywhere outside a
   string literal — masked whole-file, not merely inside call spans. The block's
   backticked `model=` survived the mask. The assertion is right: on Hermes the
   projection strips the parameter because delegate_task has no per-call model
   at all, so instructing the orchestrator to "omit the model= parameter" is
   advice about a parameter that does not exist there. The block now says "the
   `model` parameter" and carries no bare `model=` token.

2. tests/prompt-injection-scan.security.test.cjs flagged quick.md at 50,164
   normalized chars against a 50,000 prompt-stuffing threshold. quick.md sits
   just under the line on next, so any insertion trips it — the situation
   review.md is already documented for in SIZE_ONLY_WORKFLOWS ("sat at 49,971
   chars — 29 below the threshold — so it was going to trip on whatever was
   added to it next"). quick.md joins it with the same justification. This is a
   size-finding exemption only: the file is still fully injection scanned, and
   every other security check still runs on it.

Because the canonical block can no longer carry a literal `model=`, the guard's
detector now accepts the `<!-- #2517 model-omit-on-inherit -->` marker as the
canonical signal, falling back to the inline-prose property for the four files
that predate it (plan-phase, execute-phase, scan, ship — all four match the
legacy branch). That is strictly stronger than word-proximity matching, and it
keeps the guard a property check rather than a template match.

Verified: derived guard 19/19 with 0 missing; the #2684 binding guard unchanged
at 19 files / 60 placeholders / 0 findings; no inserted block contains a bare
model= token; the masked-projection assertion passes for code-review-fix.md;
gen:golden exits 0 across all 19 runtimes; lint:ci exits 0.

6fb832a93d fix(#2684): bind scan.md and ship.md model dispatch to fields their workflows resolve (#2710)
* test(#2684): failing-first guard for unbound model= dispatch placeholders

Extends the #2517 omit-on-inherit bucket with a behavioral binding guard: every
model="{X}" in a workflow must name a field that workflow actually binds — an
init-payload key (queried for real), a shell assignment, or a declared parse
field. scan.md ({resolved_model}) and ship.md ({balanced_model}) substitute
names nothing emits, so the orchestrator invents the value (ADR-1411).

Also pins the shipped reference that seeded the placeholder and instructs the
#2517-forbidden model="inherit".

RED expected on scan.md, ship.md, and references/model-profile-resolution.md.

* fix(#2684): bind scan.md and ship.md model dispatch to fields their workflows resolve

scan.md:85 passed model="{resolved_model}" and ship.md:486 passed
model="{balanced_model}" — names neither workflow's init payload emits.
init.map-codebase emits mapper_model; init.phase-op emits no model field at
all. With no source for the substitution the orchestrator invents a value, so
model_overrides/model_policy are silently inert at both sites — the invisible
partial application ADR-1411 prohibits.

- scan.md: declare the init fields in a Parse JSON line and substitute
  {mapper_model}, matching its sibling map-codebase.md.
- ship.md: ref.agent is only known at runtime, so resolve it per hook via
  query resolve-model and dispatch with {HOOK_AGENT_MODEL}, following the
  same NAME=$(...) → model="{NAME}" convention every other shell-resolved
  dispatch in the corpus uses (code-review.md, secure-phase.md, ui-phase.md).
- Both sites now carry the #2517 rule: omit model= entirely when the resolved
  value is "inherit" or empty. A bare rename would have traded a dangling
  placeholder for model="", which 404s on non-Claude runtimes — an agent type
  absent from the profile table resolves to the empty string, which is exactly
  ship.md's case.
- references/model-profile-resolution.md was the seam: it shipped the
  copy-pasteable {resolved_model} snippet scan.md inherited, used the stale
  Task( spelling, and instructed passing model="inherit" outright. Rewritten
  to teach the real binding convention and the omit rule.

Two defects surfaced while fixing this and fixed inline rather than deferred:

1. ref.agent originates in a capability manifest, which may be third-party.
   Resolving it at runtime made this the first place that value reaches a
   shell command, so ship.md now validates its shape before interpolating and
   skips the hook when it fails — matching code-review.md's existing
   defense-in-depth pattern. Covered by a test that runs the shipped regex
   against real agent names and injection payloads.
2. The reference doc's omit example first placed a literal model= inside an
   Agent(...) comment, which tripped the #2284 fail-closed Hermes projection
   guard (bin/install.js:3704) and refused the install outright. Moved out of
   the call span; gen:golden is green across all 19 runtimes.

Guard tests extend the existing #2517 bucket: every model="{X}" in a workflow
must name a field that workflow binds — an init-payload key queried for real,
a shell assignment, or a declared parse field.

Behavior change (Hyrum's Law): the scan mapper now runs on the catalog-resolved
model rather than the session model. The omit path is unchanged. Disclosed in
the changeset body.

Fixes #2684

* fix(#2684): validate capability-supplied ref.agent in-context, not in the shell

The first cut of the ref.agent guard was placed after the injection point it
was meant to close. It instructed the orchestrator to substitute the untrusted
manifest value into a shell assignment and test it there:

    HOOK_AGENT="<the ref.agent value>"
    if [[ "$HOOK_AGENT" =~ ^[A-Za-z0-9][A-Za-z0-9._-]*$ ]]; then …

Substitution happens before bash parses anything, so a manifest supplying
`x"; touch /tmp/pwned; echo "` yields three statements and runs the middle one
unconditionally — the regex fires afterwards and protects nothing.

ship.md now requires the check to run in-context, the same way the workflow
already reads activeHooks ("do NOT pipe it through a shell parser"), and to
skip the hook outright on a mismatch. Only a value that has already matched
^[A-Za-z0-9][A-Za-z0-9._-]*$ ever reaches a command line. The guard test asserts
the ordering — the in-context requirement and the absence of any raw shell
assignment — not just that the pattern rejects metacharacters, since a pattern
alone was exactly what gave false assurance here.

Also corrects the empty-string explanation in references/model-profile-
resolution.md. model_profile:"inherit" resolves to the literal "inherit", not
"" (model-resolver.cts:395), and an unknown agent takes the empty-string path
via resolve_model_ids:"omit" rather than by absence alone — the doc claimed all
three produced "". The workflow instructions were already correct (omit on
"inherit" OR empty); only the rationale in the citable reference was wrong.

Both found by the isolated adversarial review pass for #2684.

28e486faf7 fix(#2608): fail closed when git add fails during commit staging (#2693)
* fix(#2608): fail closed when `git add` fails during commit staging

`cmdCommit` ignored `git add` failures. #2523 had already stopped a failed path
entering the commit pathspec, but skipping it silently left two bad outcomes,
both reproduced against the pre-fix build:

- SOME paths fail  -> `{"committed":true}`. `git commit` still ran and PARTIALLY
  committed the subset that happened to stage, under a message describing the
  full requested scope.
- EVERY path fails -> `{"reason":"nothing_to_commit"}`, which is not what
  happened and points the operator nowhere.

In both cases git's original `add` stderr was discarded, so the user saw a
downstream `commit_failed` / pathspec error naming an innocent file — the
symptom reported in the issue from a linked worktree whose git directory was
outside the managed writable root.

Staging failures are now collected and the command fails closed BEFORE
`git commit` runs, returning the issue's specified shape:

  { committed: false, hash: null, reason: "staging_failed",
    file: "<first failing path>", error: "<original git add stderr>",
    failures: [ { file, error, timed_out }, ... ] }

A timeout is distinguished as `staging_timeout` (issue AC5) using the projection's
SIGTERM+ETIMEDOUT signal — the same idiom worktree-safety.cts uses. The check is
placed ahead of the `nothing_to_commit` branch so an all-paths-failed run reports
the staging cause rather than an empty changeset.

Unchanged: successful staging still commits exactly the declared scope and leaves
unrelated staged files alone; an explicitly-named file that does not exist is
still skipped rather than staged as a deletion (#2014/#2523), and a request where
every named file is missing still reports `nothing_to_commit` — no `git add` ran,
so there is no staging failure to report.

Regression tests inject the failure by monkeypatching `execGit` on the projection
module (per CLAUDE.md, over `chmod 0o000`, which does not fault under root and
would make the tests vacuous), driven in a `node -e` child because `output()`
writes via `fs.writeSync(1, …)` and cannot be captured in-process. Pre-fix, 6 of
the 10 assertions fail; post-fix all pass.

Closes #2608

* fix(#2608): roll back the index, guard the sibling surfaces, document the new reasons

Six findings from the orthogonal review of the first commit, all fixed here.

1. A `staging_failed` return left the index PARTIALLY STAGED. The paths that did
   stage stayed in the index with no commit made and no cleanup, so the next bare
   `git commit` would sweep them up — the same silent partial commit this fix
   exists to prevent, deferred one step. (Pre-fix the partial state at least got
   consumed by the incorrect commit.) The staging failure path now resets the
   paths it staged, matching cmdPrSubrepo's established rollback-then-error
   convention. The reset is scoped to what THIS call staged — paths the caller
   had already staged are captured up front and excluded, so a caller's own work
   is never destroyed — and is best-effort, since an unwritable index (the very
   failure being reported) cannot be reset either.

2. `cmdCommitToSubrepo` still had the identical defect: a failed `git add` was
   dropped silently and the function committed the subset that happened to stage,
   discarding git's stderr. It now fails closed per sub-repo with the same
   staging_failed/staging_timeout reasons and the same scoped rollback.

3. The `git rm --cached --ignore-unmatch` branch (default mode, for a planning
   file that no longer exists on disk) still discarded its result. It mutates the
   index exactly like `git add`, and `--ignore-unmatch` already makes "no such
   path" a success, so a non-zero exit there is a real I/O failure — now routed
   through the same staging-failure path.

4. `agents/gsd-executor.md` documented the commit envelope as an exhaustive
   three-shape enum and pattern-matched only `nothing_to_commit | commit_failed`.
   It is the sole consumer doc for this surface, so the new reasons are added
   with explicit guidance not to retry (a retry hits the same unwritable index),
   and the "one of three shapes" framing is corrected.

5. The default (non---files) staging path and `--amend` are now covered by tests.
   Both were already guarded by the first commit but unexercised.

6. The changeset framed the fix as `--files`-only; it applies to default and
   sub-repo commits too, and now mentions the rollback.

Regenerated the agent size baseline and the 18 golden install-parity fixtures for
the gsd-executor.md edit.

16 assertions across both surfaces verified against the built lib.

* test(#2608): update the #2523 out-of-repo contract to the new staging_failed reason

The remote test run surfaced this: `#2523: out-of-repo --files path is rejected by
git` asserted `reason: 'nothing_to_commit'`, and now gets `staging_failed`.

This is a deliberate contract improvement, not a papered-over failure. The old
reason existed only because a failed `git add` was skipped and the resulting empty
`stagedPaths` fell through to the empty-changeset branch. But "nothing to commit"
is not what happened — the caller named a file and git refused it — and that
misreport is exactly the class of defect #2608 closes. The result now carries the
offending path and git's own message ("… is outside repository at …"), which is
strictly more actionable for the same condition.

#2523's two substantive invariants are untouched and still asserted: no commit is
created, and the index is left clean. Two assertions are ADDED (the path is named,
git's message is preserved) so the richer contract is pinned rather than merely
allowed.

Per CONTRIBUTING, a stale-test correction rides its own commit.

* fix(#2608): compact the executor doc addition to stay under the agent LARGE cap

The remote test run failed: `gsd-executor.md is 49217 bytes — exceeds the LARGE
hard cap of 49152`. The file was already at 48596 (556 bytes of headroom) and the
new commit-envelope documentation pushed it 65 bytes over.

The cap is a red line, not a budget to raise, so the addition is compacted rather
than the cap moved: four lines instead of eight, keeping the load-bearing facts —
the two new reasons, that nothing was committed and the index was rolled back,
that `file` + `error` should be surfaced, and that retrying is wrong because a
retry hits the same cause. Dropped only the restatement of the linked-worktree
example (already in the changeset and PR) and the `failures[]` field (a superset
of `file`/`error`, discoverable from the payload).

Net addition is now 276 bytes; the file sits at 48872 with 280 bytes of headroom.
Extracting the agent's shared boilerplate to references/ would buy much more, but
that is a restructuring of the executor agent and does not belong in a
commit-staging bugfix.

Agent size baseline and the golden install-parity fixtures regenerated.

2c44241a0b fix(#2605): make dropped local-server reviewer lanes loud instead of silent (#2689)
* fix(#2605): make dropped lm_studio / llama_cpp reviewer lanes loud, not silent

The `lm_studio` and `llama_cpp` reviewer legs in `gsd-core/workflows/review.md`
carried the same empty-output defect as the claude/gemini legs (#2494, fixed in
#2592) in a worse variant: when the local endpoint was unreachable or returned
empty content, they wrote NOTHING to `{run_dir}/gsd-review-<leg>.md`. There was
no `[ ! -s … ]` stub at all, so the file never existed, `write_reviews` omitted
that reviewer's section, and the outcome was indistinguishable from the reviewer
never having been selected.

Two diagnostic holes are closed, because an OpenAI-compatible server fails in two
ways that leave evidence in different places:

- Transport failure (endpoint unreachable): curl writes to stderr and exits
  non-zero. Both legs used `curl -s`, which suppresses curl's ERROR text as well
  as the progress meter, and then discarded stderr to `/dev/null` — so there was
  nothing to capture even in principle. Now `-sS` with stderr to a `.err`
  sidecar, matching the claude/gemini/codex legs.
- Application failure (HTTP 4xx/5xx): curl exits 0 and the error JSON is in the
  response BODY, so stderr is empty and only the body is evidence. The stub
  appends the raw response. The `llama_cpp` leg additionally piped curl straight
  into `jq`, throwing the body away before anything could inspect it; the
  response is now captured to a variable first, as the `lm_studio` leg already
  did.

The existing `>&2` warning is kept and now points at the stub file.

Failing-first verified by extracting both shipped blocks and running them under a
real bash against a stubbed curl: pre-fix, all three failure modes produce NO
review file and no `.err` sidecar for both legs; post-fix, each produces a
diagnosable stub, and a successful review still passes through untouched.

Closes #2605

* fix(#2605): close the remaining silent-drop paths the review surfaced

Four defects found by the orthogonal review of the first commit, all fixed here
rather than deferred (they are the same defect class the issue is about, and
three of them sit inside the code that commit touched).

1. CodeRabbit leg was still unguarded. `coderabbit review --prompt-only
   2>/dev/null > file` with no `[ ! -s … ]` stub — the last leg still shaped like
   pre-#2494 code. A missing or unauthenticated binary left a zero-byte file that
   write_reviews rendered as "ran cleanly, nothing to report". It now captures
   stderr to a `.err` sidecar and emits the same diagnosable stub as every other
   leg. This is the leg the next issue in the #2494 -> #2592 -> #2605 series
   would have been about.

2. The budget-skip path dropped the lane just as silently. When
   `prepare_trimmed_prompt_for_reviewer` fails, `*_SKIP=1` bypasses the entire
   block — guard included — so no file was written and the only trace was a
   stderr warning nothing persists. All three local-server legs now write a
   "review skipped: prompt budget too small" stub on that path.

3. Whitespace-only replies evaded the guard. `[ ! -s … ]` counts BYTES, and
   command substitution strips trailing newlines but not spaces, so a reply of
   `"   "` was written out and passed as a "successful" but vacuous review — the
   same indistinguishable-from-success outcome the guard exists to prevent. A
   `case` glob now normalizes whitespace-only content to empty.

4. `echo "$VAR"` swallowed option-like content. bash's builtin `echo` treats a
   value of exactly `-n`/`-e`/`-E` as a flag and writes 0 bytes, which would trip
   the empty guard and DISCARD a genuine reply. Switched to `printf '%s\n'`, the
   idiom the OpenCode leg in this same file already uses for this reason.

Also brings the Ollama leg to parity while it is in hand: it always emitted a
stub so it never silently vanished, but it was the least diagnosable of the three
local-server legs — bare `-s`, stderr to /dev/null, and the response piped
straight into jq so the error body was discarded unread.

Verified by extracting all four shipped blocks and running them under a real bash
against stubbed CLIs: 22 cases (7 per local-server leg x 3, plus CodeRabbit) all
produce the contracted output, and a successful review still passes through
untouched on every leg.

The remote test run on the prior commit failed with 19 "golden parity —
<runtime>" mismatches. review.md is installed into every runtime's tree, so
editing it changes its content hash in all 19 golden fixtures.

Regenerated with `npm run gen:golden`; the diff is exactly one line per fixture

This is the second ripple of a workflow edit, alongside

a5633bb32f enhance(#2671): brand raw vs calibrated token types so double-application is a compile error (#2676)
* test(#2671): add failing-first brand-typing compile fixtures

* feat(#2671): brand raw vs calibrated token types

* refactor(#2671): hoist type-compile into a before() hook

Two review responses:

- The fixture compile ran in the describe() body, so it executed at
  collection time even when the block was filtered out, and a failed
  precondition collapsed eight independent assertions into one opaque
  describe-level failure. A before() hook is this repo's documented
  idiom and preserves per-test granularity.

- parseTokensFlag now records WHY it returns an unbranded number: it
  validates the magnitude of --tokens, but the basis is decided by
  --calibrated, so branding here would be wrong for half its callers.
  The assertion belongs to cmdEstimateCheck, its only caller.

* test(#2671): pin each brand diagnostic to its OFFENDING marker

Adversarial review demonstrated that asserting only exactly-one-diagnostic-
at-code-N is not airtight. Repairing a fixture's brand violation while
injecting an unrelated error of the same code (a string passed as the
budget argument) still yielded exactly one TS2345, so the fixture would
have reported green while no longer testing its regression at all.

Each bad-* fixture now routes its violating value through a const named
OFFENDING, and the test asserts the diagnostic's start offset falls inside
that node — located through the AST, so it survives reformatting and never
pattern-matches source text. Replaying the proof-of-concept against the new
assertion rejects it: the diagnostic lands on the budget literal, not the
marker.

Also corrects a doc comment that claimed the program type-checks all of
src/; it covers phase-estimation.cts and its transitive dependencies.

c7c2fe3c2b fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd (#2680)
* fix(#2587): resolve cursor hook workspace from workspace_roots, not cwd

gsd-cursor-session-start.js and gsd-cursor-stop.js both resolved the project as
path.join(process.cwd(), '.planning', 'STATE.md'). Under the cursor-agent CLI,
hooks are invoked with cwd set to the Cursor config dir (~/.cursor), not the
workspace — so the lookup always missed. sessionStart could only ever emit the
"no .planning/ workflow found" nudge and stop's verify-work reminder could never
fire, even with .planning/STATE.md sitting in the workspace. Slash commands were
unaffected, which is why only the hook layer looked blind.

Both hooks already buffered stdin into `raw` and never parsed it; the payload's
workspace_roots carries the real path.

Multi-root was left open in the report ("first root vs any root"). Resolved
forward: prefer the first root that actually carries .planning/STATE.md, so a
workspace whose GSD project is not the first root still resolves — strictly
better than first-root-only and identical to it in the single-root CLI case.
Falls back to roots[0], then to cwd, keeping IDE behavior unchanged if the IDE
ever invokes hooks from the workspace.

The resolver is duplicated verbatim across the two scripts rather than shared via
hooks/lib/: these hooks ship standalone, and a new hooks/lib/ file must be
registered in the GENERATED installer's GSD_HOOK_LIB_FILES allowlist — the
installer-omits-shipped-file class that yields MODULE_NOT_FOUND at runtime. Per
CLAUDE.md "Generative Fix Divergence", the duplication carries a parity assertion
so the copies cannot drift.

Failing-first, demonstrated by direct invocation with cwd != workspace:
  pre-fix  sessionStart -> "no .planning/ workflow found"   stop -> {}
  post-fix sessionStart -> ".planning/STATE.md is present"  stop -> reminder

tests/fix-2587-cursor-hook-workspace-roots.test.cjs spawns the real scripts as
child processes with a cwd lacking .planning/ and workspace_roots pointing at it.
Boundary coverage on the roots array (0 / 1 / 2 entries), plus malformed-JSON
fail-open, junk-entry filtering, the parity assertion, and a guard that neither
script resolves .planning from cwd again.

* fix(#2587): extend workspace_roots fix to subagentStart; keep cwd a candidate

Three findings from the isolated review, all fixed.

1. MISSED SITE (high). gsd-cursor-subagent-start.js carried the identical
   defect at line 43 — its own header documents workspace_roots in the input
   schema, but it resolved .planning/ from process.cwd() anyway. Under the
   cursor-agent CLI that meant every Cursor subagent (planner, executor,
   verifier) started with "no .planning/ workflow found" and no phase context.
   The report named only sessionStart and stop; the defect class was wider.
   Verified pre-fix vs post-fix by direct invocation with cwd != workspace.

2. SEMANTIC NARROWING (medium). The first cut searched only workspace_roots and
   fell back to cwd solely when the array was EMPTY. So when roots were supplied
   but none carried .planning/ while cwd did, the hook reported absent — where
   the pre-fix code, which always used cwd, reported present. That contradicted
   the fallback's own stated intent of preserving IDE behavior. cwd is now a
   CANDIDATE in the search (`[...roots, process.cwd()]`), so the fix is a strict
   superset of both the old behavior and the CLI fix, never a narrowing.

3. STALE GOLDEN FIXTURES (high, would have failed CI). The golden-install-parity
   fixtures store a content hash per installed file; these three hooks appear in
   13 of the 19 runtime fixtures. Regenerated via `npm run gen:golden` — the
   diff is exactly the three hook hashes in exactly those 13 runtimes.

Tests extended: subagentStart resolution via workspace_roots; the stop hook's
absent branch (previously only session-start's was covered); an explicit
regression guard that a project at cwd is still found when roots miss; parity now
asserts all THREE copies byte-identical; and the cwd guard sweeps the whole
RESOLVING_HOOKS list so a future hook in this family cannot be left on cwd.

* refactor(#2587): extract cursor workspace resolution to a shared hooks/lib module

The duplicate-plus-parity-test approach was the wrong call. The reported issue
named two hooks; a third (subagentStart) had the identical defect. That is the
signature of a systemic problem, and three copies of a resolver guarded by a
parity assertion is a divergence risk maintained by hand rather than a fix.

hooks/lib/cursor-workspace.js is now the single implementation. All three Cursor
hooks require it; none defines a local copy. Divergence is prevented
structurally instead of by asserting three copies stay byte-identical.

The reason duplication looked necessary was real, and is fixed properly here
rather than worked around: Cursor sets hostBehaviors.skipSharedHooksInstall
(#2089), so it never reaches the installer's bulk hooks/lib copy — it was the
ONE runtime shipping these hooks WITHOUT hooks/lib (verified against all 19
golden fixtures: cursor had the hook scripts, no lib). A naive require would
have thrown MODULE_NOT_FOUND at load, BEFORE each hook's own try/catch, wedging
every session on precisely the runtime this bug is about.

writeCursorHooksJson (src/runtime-hooks-surface.cts) now stages the hooks/lib
helpers the staged scripts actually require, discovered by scanning their
require('./lib/…') calls rather than a hardcoded name — so a future helper
cannot be silently omitted. This is narrower than flipping
skipSharedHooksInstall, which would wrongly pull in every shared hook.
cursor-workspace.js is also added to GSD_HOOK_LIB_FILES so uninstall and the
manifest manage it for the runtimes that do receive hooks/lib.

Verified against a REAL install (runMinimalInstall, cursor/global): the helper
is staged, and all three INSTALLED hooks resolve the workspace end-to-end from a
cwd that is not the project.

Also closes the review gap that the stop hook was excluded from the
cwd-candidate regression loop — it now sweeps RESOLVING_HOOKS. The byte-parity
test is replaced by a structural guard (every hook requires the shared module,
none redefines it) plus a new install test asserting the helper is staged and
the installed hook actually loads against it.

* fix(#2587): fail loud on a missing hook lib source; drop unsubstituted version marker

Two findings from the installer-focused review.

H1 — the staging step's `if (!fs.existsSync(libSrc)) continue;` silently defeated
the very guarantee it was added for. Reproduced: delete hooks/lib/cursor-workspace.js
from source, run the cursor install — it exits 0, prints "Done!", and ships the
three hook scripts with an EMPTY hooks/lib/. The installed hook then throws
`Cannot find module './lib/cursor-workspace.js'` at load, before its own
try/catch, wedging every session — and nothing surfaces until a user hits it.
The scan protected against a required-but-UNLISTED helper while leaving
required-but-MISSING wide open (typo, bad rebase, an accidental delete).
It now throws: a missing helper source is a packaging bug and aborts the install.

M1 — hooks/lib/cursor-workspace.js carried a `gsd-hook-version: <placeholder>`
marker that NOTHING substitutes: copyLibDir stamps .sh files only, and
writeCursorHooksJson's staging applies just the colon-to-dash rewrite. Verified
the literal was reaching disk on both the bulk (--claude) and Cursor
(--cursor) paths. hooks/lib/git-cmd.js — the only pre-existing hooks/lib/*.js —
carries no such marker, so this was newly introduced, not inherited. Marker
removed, matching that precedent, with a note on why. (The explanatory comment
deliberately does not spell the token out, or it would reintroduce the literal.)

M2 — the require-scan regex demanded the exact compact form, so
`require( "./lib/x.js" )` would silently fail to stage its helper and compound
H1. Now tolerant of interior whitespace and either quote style.

Regression test added for H1 — the reviewer confirmed the invariant had zero
coverage repo-wide: a source tree carrying the hooks but no hooks/lib/ must make
writeCursorHooksJson throw rather than produce a broken install.

Re-verified end to end: the missing-source case throws, no unsubstituted literal
ships, and the installed hook still resolves the workspace from a foreign cwd.

c87f6f358e enhance(#1854): offer restore for user-added files backed up on update (#2679)
* test(#1854): failing-first coverage for user-files-backup restore

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

* feat(#1854): offer restore for user-added files backed up on update

Adds a restore-custom-files gsd-tools verb and wires it into update.md as a
restore_custom_files step: plan, compatibility-check against the newly
installed release, then restore only on explicit opt-in. The backup is never
deleted, a shipped path is never overwritten, and a single unwritable entry
does not abort the rest.

Also drops the jq pipe from update-context field extraction (#2589 class,
missed by that sweep) and repairs a broken code fence in docs/CLI-TOOLS.md.

* fix(#1854): reject symlinked restore destinations and backup roots

Self-review of the restore path found two write-through holes: copyFileSync
follows a symlinked destination, so a link planted at the restore target wrote
outside the config dir with every ancestor still a real directory; and statSync
on the backup root followed a link, letting the walk read arbitrary files and
present them as the user's own backup. Both now lstat.

Also marks the report's path/detail strings as untrusted data in update.md so
the rendered step cannot carry instructions into the runtime model.

* test(#1854): move the update-context jq guard into the #2589 sweep

update.md joins the AUDITED list rather than carrying a duplicate assertion in
the backup-restore suite, and the guard gains a negative-proof companion so
'no jq pipe' cannot pass by the fields simply no longer being read.

* fix(#1854): validate manifest files map shape before trusting it

Security review flagged that Object.keys on a non-plain-object files field
yields numeric-index keys matching nothing, so the managed-path check dies
silently while manifest_found still reports true. Shape, not just type
(ADR-227): an array or scalar files map is now an unusable manifest.

* fix(#1854): size the restore prompt by eligible_count

Spec review found the prompt was driven by entries.length, so a backup holding
only blocked entries asked "Restore 1 file(s)?" when accepting would restore
zero. The question now reads eligible_count, and an all-blocked backup reports
its reasons instead of offering a choice that cannot be honored. The decline
path names the resolved backup_dir rather than the bare directory name.

* test(#1854): use t.skip on hosts without symlink support

A bare return in a node:test body registers as a PASS, so the four symlink
guards silently reported green on unprivileged Windows instead of skipping.
Adds the dangling-link destination case the security review called out, and
moves outside-dir teardown to t.after so a failing assert cannot leak it.

* fix(#1854): unfence restore hint, regen goldens, widen install timeout

Three gate failures from the c99d612a5 run, all root-caused:

1. capability-registry (3): update.md's decline message put an instructional
   'gsd-tools ...' line in an UNTAGGED fence, and the guard treats untagged
   fences as shell blocks. Retagged both display blocks as text and switched
   the hint to the resolved 'node <config-dir>/.../gsd-tools.cjs' form users
   can actually paste.

2. golden-install-parity (19): update.md and gsd-tools.cjs ship, so every
   runtime fixture moved. Regenerated; the diff is exactly those two hashes
   per fixture, no other drift.

3. install.test.cjs (5): one real failure, four cascades. The Cursor suite's
   before hook died on 'spawnSync ETIMEDOUT' at the 60s cap while the node22
   lane passed the SAME commit in 12.7s. A full install measures 13-30s idle,
   so 60s was under 2x headroom and shrinks with every file added to the
   payload. Raised to 120s, matching the heavy case already in this file.
