b901d1e06f feat(#1953): complexity-triggered refactor extension point (execute:post) (#3261)
* test(#1953): failing-first suite for the complexity-triggered refactor hook

60 behavioral cases against src/complexity-trigger.cts, which does not exist yet:
decision-point counting, the comment/literal stripping leak surface, threshold and
jump-delta boundaries at limit-1/limit/limit+1, stable-anchor baseline semantics,
and fs fault injection via mock.method. Two fast-check properties assert that
stripping never manufactures a decision point and that comments and string
literals are score-neutral.

Also registers the refactor-trigger capability manifest (inert until
refactor.trigger_enabled) and regenerates the capability registry and matrix.

Verified RED on the remote runner before any implementation exists.

* feat(#1953): complexity-triggered refactor extension point

Adds the opt-in refactor-trigger capability. After a phase executes, an
execute:post step measures per-function complexity for the files the phase
touched and writes a scoped refactor proposal when a function crosses the
configured threshold or drifts past its recorded anchor.

Design notes worth carrying:

- The signal is computed in-core (decision-point counting over comment- and
  literal-stripped source, Node builtins only) rather than via Memtrace or a
  shelled-out analyzer. The hook fires as a deterministic CLI, not an agent
  with MCP tools, and core takes no external dependencies — this is the only
  option a behavioral test can bind to. The metric sits behind a seam.
- The baseline is a stable anchor, not a rolling value: set on first
  observation, moved only on disposition. A rolling baseline makes the delta
  the single-phase change, so a function creeping +2 per phase never trips a
  delta of 5 and the jump check adds nothing over the absolute threshold.
- Strict mode records an open deviation window in the broken-windows ledger
  rather than declaring its own ship:pre gate. ship.md has no generic ship:pre
  gate dispatch — only two hardcoded branches — so a third gate of any kind
  would be declared and never evaluated.
- The gate clears on the proposal being dispositioned, never on the score
  improving. A blocking complexity number is one an executor can satisfy by
  splitting a coherent function in two.

execute-phase.md gains a generic execute:post step-dispatch contract; it
previously matched only ref.skill == "code-review", so any other step
registered there was declared and never run. The code-review branch is
unchanged.

Full rationale in ADR-1953.

* fix(#1953): close git option injection and symlink escape in the refactor hook

Three findings from the isolated security review, all fixed inline.

HIGH — changedFilesSince interpolated the --since value into a revision
token placed before the -- separator. A -- only stops PATHSPEC parsing of
arguments after it; git still option-parses what comes before. So
--since '--output=/tmp/x' became --output=/tmp/x..HEAD, which git accepts
as --output=<file> and uses to redirect diff output — an arbitrary write.
Fixed with --end-of-options before the revision range plus a conservative
ref validator. The validator deliberately permits ~ ^ @ { } because those
are legitimate git REVISION syntax (HEAD~1, main@{yesterday}) as distinct
from ref-NAME syntax; --end-of-options is the actual barrier. The doc
comment asserting the trailing -- was sufficient was wrong and is corrected.

MEDIUM — resolveConfinedPath confined by string prefix only, so a symlink
committed inside the repo passed the check (its own path is under cwd) and
readFileSync then followed it outside the root. Now lstat-checks for a
regular file and skips anything else with REFACTOR_FILE_UNREADABLE, so one
bad path skips one file and the run continues.

LOW — the new execute:post dispatch contract showed the gsd_run example
before the rule requiring ref.command be validated first. That prose is
executed by an agent, so textual order is execution order. Reordered.

* fix(#1953): make the analyzer able to see TypeScript at all

Found by running the shipped analyzer over its own source: it reported
functions=1 for a 940-line module with 24 function forms. A return-type
annotation or a generic parameter list made a function invisible —
`function f(a): number {}` and `function f<T>(a: T): T {}` both detected as
zero. Since gsd-core is written in .cts and the capability declares
.ts/.cts/.mts analyzable, the feature silently found nothing in this repo's
own primary language while reporting success. A safety net that reports
"all clear" because it cannot see is worse than no safety net.

All 98 tests passed over this, because every fixture was plain JS — the
exact failure the test matrix's own "assert against the shape production
uses" warning describes. Adds a TypeScript-shapes suite covering return
types (including unions, generics, object literals and type predicates),
generic parameter lists (constrained and defaulted), export/async/generator
combinations, annotated arrows, class-method modifiers, and optional/
default/rest params — plus the two traps: an overload signature has no body
and must not count, and `a < b && c > d` is a comparison, not a generic.
Detection now reports 24/37/21 functions for the three source files, which
matches a hand count exactly.

Also from review:

- The strict-mode ledger dedup identified entries by parsing a prose
  description string. That is banned by CONTRIBUTING's raw-text-matching
  rule and was a real bug: the "exactly one window per untriaged proposal"
  guarantee rested on prose matching, so rewording a description or editing
  WINDOWS.md by hand silently produced duplicates. Now matches structurally
  on kind + phase + file + line.
- A property test asserted on the stripper's output text. Reframed to
  assert the same invariant through analyzeSource's score.
- nextBaseline's `candidates` parameter has been dead since the anchor
  change; removed from the signature and all call sites.
- Extracted the duplicated require-or-degrade and capability-check
  boilerplate.
- ADR-1953's Implementation bullet still named a `refactor.ship-gate` in
  check-command-router.cts — a leftover from the design cut D6 rejects.
  That file is untouched and no such gate exists. Removed.

* fix(#1953): keep execute-phase.md under its byte ceiling; un-vacuum the large-file test

Five of the seven remote-runner failures were one cause: the execute:post
dispatch contract, written out inline, grew execute-phase.md 1876 bytes
(93,400 -> 95,276) against a frozen PRE_PHASE6 ceiling of 93,600. A drift-ack
does not clear that — tests/phase6-capstone-conformance.test.cjs and
tests/fix-2285-claude-orchestration-wiring.test.cjs assert the file is
literally under the cap.

The contract now lives in gsd-core/references/loop-hook-dispatch.md, which
already claimed to be the point-agnostic dispatch reference and already
documented ref.skill and ref.agent. It gains the ref.command shape, its
in-context validation rule, the advisory-by-construction statement, and a
note that a point whose workflow hand-rolls one kind is not implementing
this contract. execute-phase.md now defers to it in one line: 145 bytes of
growth, 55 B of headroom under the cap. Better placement than the first cut
— the reference was overstating its coverage, and this makes the claim true
rather than duplicating prose next to it.

Acknowledged by appending to tests/emitted-drift-acks/2930-*.json rather
than a new 1953-*.json: two ack sources may never name the same path, and
that fragment is already the accumulating ack for this file.

Sixth and seventh failures: analyzesLargeFileWithinBounds tripped its own
vacuity guard — the fixture generated ~480 KB against a `> 500000` assert,
so the guard fired and the three assertions after it never ran. The test
has been vacuous since it was written. The matrix row specifies ~1 MB, so
N goes 8000 -> 20000 (1.17 MB, 17% margin) and the guard to > 1_000_000.
Verified by reproducing the exact body against the compiled module: 1168888
bytes, 118 ms, all four assertions hold.

Refs #1953

* fix(#1953): fold the execute:post step deferral into the existing resolve line

The remaining two failures were one test: execute-phase.md carries a SECOND,
tighter assertion than the 93,600 ceiling — `<=93400`, which is exactly its
current size. The file cannot grow by a single byte. My previous fix got it
under 93,600 but not under 93,400, so it still failed. ("H." in the report is
just the parent describe of that same test, not a separate defect.)

Rather than add a paragraph, the deferral now REPLACES the existing hook
resolution line. It read:

  Resolve active step hooks from `EXECUTE_POST_HOOKS_JSON` where
  `kind == "step"` and `ref.skill == "code-review"`.

which is the bug itself written down — only code-review was ever dispatched.
It now reads:

  Dispatch each `kind == "step"` hook per
  @gsd-core/references/loop-hook-dispatch.md. For `code-review`:

The following prose already begins "If no active code-review step hook
exists", so it reads correctly and the code-review handling is untouched.
Net effect on the file is -11 bytes: 93,400 -> 93,389, under the margin
assertion rather than merely under the ceiling.

That also removes the need for a drift-ack: the file shrank, so there is no
growth to acknowledge, and the append to the shared 2930-*.json fragment is
reverted. Leaving it would have shipped a claim of "145 bytes of growth"
that is no longer true, on a file six other issues share.

The test's own comment states the principle this ended up honoring: "the host
loop must stay small — optional-feature detail belongs in the capability
fragment, not the host workflow." Putting the dispatch contract in the
reference rather than inline is that rule, applied.

Refs #1953

* fix(#1953): keep the code-review hook literal the workflow test requires

tests/code-review.test.cjs extracts the <step name="code_review_gate"> block
and asserts it contains `ref.skill == "code-review"` verbatim. The previous
commit replaced the line carrying that literal, so the token vanished and the
test went red — a fair assertion: code-review IS the bespoke branch there and
the workflow should still name it.

Restored inside the same one-line deferral, which now reads:

  Dispatch `kind == "step"` hooks per @gsd-core/references/loop-hook-dispatch.md.
  `ref.skill == "code-review"`:

93,396 bytes — still under the `<=93400` margin assertion and 4 bytes below
the base, so the file continues to shrink rather than grow.

Because three consecutive runs were each reddened by a different assertion on
this one file, this change was verified by sweeping ALL of them at once rather
than one run at a time: every test under tests/ that reads execute-phase.md or
references/loop-hook-dispatch.md was located by resolving its path constants,
and each content/size assertion was evaluated directly against the working
tree — 22 assertions, plus two real executions (gen-section-manifest --check,
and emitted-attribution's full real-tree differential). All pass.

That sweep also confirms the earlier judgement call: the net change to
execute-phase.md is a SHRINK, and the size ratchet only gates growth, so
reverting the append to the shared 2930-*.json ack fragment was correct — an
ack would have been both unnecessary and factually wrong.

* chore(#1953): backfill changeset pr number to 3261

* docs(#1953): add the missing how-to for acting on a refactor proposal

Reference and explanation shipped (COMMANDS.md, CONFIGURATION.md,
FEATURES.md 159, ADR-1953) but the Diataxis how-to quadrant did not, and
that is the one a user reaches for. CONTRIBUTING's required-docs table is
'new command -> COMMANDS.md + FEATURES.md', so CI was green on a gap.

Enabling this feature is genuinely multi-step and no single page walked it:
turn it on, tune the threshold, understand advisory vs strict, discover
that strict needs a SECOND toggle on a DIFFERENT capability, and know what
to do when a proposal appears. The two-toggle subtlety in particular was a
footnote in a config table; here it is a section with both commands.

Follows the shape of its closest siblings, resolve-edge-coverage-findings
and resolve-prohibition-findings — both 'the loop surfaced a finding, here
is what to do with it'. Includes a reason-code table for the silent cases,
since the analyzer is deliberately quiet in six situations and a user who
expected a proposal needs to tell 'nothing to report' from 'could not look'.

Indexed from docs/README.md beside the other loop how-tos.

Docs-only: exempt from the push gate, no re-verification, pass marker on
2af188b4 untouched.

* feat(#1953): warn when strict mode is on but nothing will actually block

Closes acceptance criterion 5, which I had wrongly marked satisfied.

refactor.trigger_strict records an untriaged proposal as an open deviation
window, but a ship only STOPS if workflow.windows_enforce is also on — a
toggle owned by the broken-windows capability that this feature neither sets
nor requires. So a user could enable strict, believe ship was gated, and find
out otherwise at ship time.

The split itself stays: requires:["broken-windows"] would force-install the
ledger on advisory users who never enable strict, and a ship:pre gate of our
own would never fire because ship.md has no generic ship:pre gate dispatch.
What was missing was discoverability, so that is what this fixes.

`refactor evaluate` now emits a typed REFACTOR_STRICT_NOT_ENFORCING warning,
naming the exact remediation command, whenever strict is on and either
workflow.windows_enforce is off or broken-windows is unavailable. It fires
only on a run that produced a candidate — with nothing to block on there is
nothing to warn about, and warning every run would be noise.

Reads workflow.windows_enforce through the same resolveConfigKey walk the
router already uses for its own keys rather than a second config reader.
Four tests cover the matrix: strict+enforce-off warns, strict+enforce-on does
not, strict+ledger-absent warns, strict-off never warns.

Also corrects a user-facing message in this same file that told the user to
run `gsd-tools config-set` — the wrong form. docs/CONFIGURATION.md and the
broken-windows capability both use `gsd config-set`, and gsd-tools is invoked
as `node gsd-tools.cjs`, so the bare form may not resolve. The two adjacent
messages in this file now agree.

c2d5b528e5 refactor(#3103): give the reap and worktree-info paths the seam their callers already have
Twenty-two branches in the orphan-reaping path are unreachable from the test
suite, and the reason is not that they are hard to reach — it is that nothing
can reach them. The reaper already accepts an injectable dependency bag, but
every test drives real git and injects only the clock and the liveness probe,
so each fail-closed return inside it has never executed under test.

The two entry points above it took no dependencies at all, so a test could not
drive them even if it wanted to. Both now accept the same bag and thread it
down, with stdout and stderr writers defaulting to the process streams. The
worktree-info probe in the base-branch resolver called its git seam directly
while a sibling function in the same file already modelled the injectable
form; it now follows that sibling rather than inventing a second convention.

Every parameter defaults to today's real implementation, so no existing caller
changes behavior. This is a testability seam, not a redesign.

Two guards are removed as genuinely dead, each excluded by a check a few lines
above it. A NaN test on a value captured by a digits-only pattern cannot fire,
because parseInt of digits is never NaN. An emptiness test on a capture group
that matched one-or-more non-space characters cannot fire either. Each site
keeps a one-line note naming the guard that excludes it, so neither gets
restored by a future reader.

A third guard was proposed for deletion on the same grounds and is NOT removed,
because the claim was wrong. The local-branch fallback returns null when git
prints output that is non-empty but names neither branch — the emptiness check
above it only catches the empty string, so a single newline reaches the
fallback with both flags false. Deleting it would have changed which branch the
resolver reports. It stays, and it gets a test.

53ea8e0664 fix(#3057): make a guard's failure distinguishable from its benign result — Wave 1 (#3088)
* fix(#3057): refuse the write when the duplicate scan cannot complete

writeManifest documents itself as a fail-closed duplicate guard: if any
existing manifest shares plan_id with a different, non-terminal job_id it must
refuse, because dispatching again would duplicate the external job.

It could not honour that. The scan reads every sibling manifest looking for the
duplicate, and an unreadable or unparseable sibling was `continue`d past. If
the corrupt file was the one holding the live duplicate, the scan found nothing
and a duplicate external job dispatched.

The asymmetry is what gives it away: a malformed TARGET refused with
malformed_existing because clobbering is unacceptable, while a malformed
SIBLING was skipped — yet siblings are the only thing the duplicate check
reads.

Adds a scan_incomplete verdict that refuses and names the offending file, so an
operator can quarantine or repair it. Fail-closed alone would let one stale
corrupt manifest wedge every dispatch for that planning dir permanently; naming
the file is what makes refusing survivable. malformed_existing is untouched, so
the target/sibling distinction stays visible. The docstring is updated — it
previously stated a rule the function did not keep.

memFs() gains an optional failReads map so these branches are reachable at all;
they had zero coverage because the fake could not express a per-file read
fault. The signature is additive and every existing caller is unchanged.

The regression is proved by a pair, not a single test. A control writes a
readable sibling holding a genuine non-terminal duplicate and asserts
duplicate_plan_id, establishing the scenario is real; the regression then makes
that same path unreadable and asserts scan_incomplete. A first draft of this
test used a corrupt-JSON fixture containing no plan_id at all while its comment
claimed otherwise — it duplicated the unparseable-sibling case and proved
nothing, which is the defect class this phase exists to remove.

* fix(#3057): make a guard's failure distinguishable from its benign result

Wave 1 of the negative-space backfill: the branches where a guard that could
not verify something reported the same value it reports when everything is
fine. That indistinguishability is the defect; every fix here makes the two
states tellable apart, and every test proves it with a pair — one for the
failure, one for the benign case. A single test cannot establish that two
states are distinguishable, which is the whole property being fixed.

state.cts phaseInventoryProvider returned null for both a real disk-scan
failure and a genuinely empty phases dir, so `state rebuild` could report
success while phase-table reconciliation never ran. It now returns a
discriminated result and the CLI surfaces phase_inventory_scan_failed plus a
reason. The reason field turned out never to have been wired into the emitted
JSON at all — it existed only as an internal variable — so a test could only
assert on the operator-facing note. It is a real field now.

state.cts treated an unreadable lock body the same as an empty one, applying
the 1-second stealable floor. A lock we cannot read is not a lock we know is
stale; an unreadable body is now held to the deadman ceiling like a live
holder.

verification.cts findStaleVerificationSummary returned null on any fs, scan or
clock failure — meaning "not stale". It now returns a discriminated
StaleCheckResult and the caller records that the check was indeterminate.

git-base-branch resolveBaseBranch returned 'main' both when no candidate branch
existed and when every git tier timed out. A diagnostics variant now reports
whether the answer was verified, and the CLI writes an unverified-fallback note
to stderr. The stdout contract five workflows parse is untouched.

worktree-safety snapshotWorktreeInventory left exists:true when statSync threw,
so a guard that could not check reported the worktree present; exists is now
tri-state and a stat failure surfaces as an 'unverified' finding.
planWorktreePrune reported 'no_worktrees' for a parse failure, which is not the
same as an empty list — and it drives a prune. It now reports 'parse_failed'.

Fixing the inventory change exposed a second fail-open in verify.cts: the
validate-health consumer silently dropped findings whose kind it did not
recognise, so the new kind would have vanished. That is closed too — worth
noting that the survey enumerated producers of degraded verdicts, not consumers
that discard them.

worktree-base-ref and state-transition gain the distinguishing signal without
changing what they do: headAbsenceVerified, and a phase-inventory scan meta.
Whether those guards should ACT differently is a product question this change
does not answer, and both are flagged rather than quietly settled.

rescueSummaryArtifacts is left alone: rescuing on an uncertain cat-file is
deliberate per #2556. It now has tests proving it, and a recorded negative
finding — git cat-file -e returns 128 for both "absent from HEAD" and a fatal
error, so "uncertain" and "certain-and-fine" are not separable at the git
level.

* test(#3057): assert typed values, not rendered text

Ten assertions in the rebuild CLI suite matched substrings of produced output —
STATE.md body fields, a markdown table row, an audit-log heading, and JSON keys
read as text. CONTRIBUTING prohibits that: if the code under test produces
text, the test asserts on its structured surface instead.

No production surface had to be built. Every one already existed and was
already compiled into bin/lib: stateExtractField for body fields,
parseMarkdownTable for the phase table, collectSection for the audit-log
section, and result.data.log — already a typed RebuildLogEntry[]. The tests
were matching rendered text sitting next to the structured data.

One of those assertions was passing for the wrong reason. `stdout.includes
('rebuilt')` matched the JSON KEY name, not a value: the dry-run path emits
`mutated` and the real path emits `rebuilt`, so it would have passed whether
the value was true or false. It now asserts the value.

external-job's refusal already had to name the offending file — that naming is
why the fail-closed variant is survivable rather than a permanent wedge — but
the tests proved it by substring of a prose message. The failure result now
carries offendingPath as its own field and the tests assert it by value. The
human message is unchanged; operators read it.

Array membership is left alone. `phaseIds.includes('99')` and
`result.updated.includes('Completed Phases')` are membership checks on real
arrays, not text matching, and converting them would weaken nothing and clarify
nothing.

* test(#3057): execute acquireStateLock instead of grepping its source

The non-EEXIST lock test asserted on the TEXT of the built .cjs and never
called acquireStateLock. It carried an allow-test-rule: architectural-invariant
exemption to permit that. A source grep proves a literal is present in a file,
not that the behaviour works — it is weaker than a liveness test, which at
least runs the code, and it was the only coverage the fatal-errno path had.

Replaced with tests that inject the errno through fs and assert what actually
happens: a fatal EACCES propagates out of acquireStateLock with zero backoff
sleeps, while EAGAIN/EINTR/EINVAL/EIO/ENOENT/ESTALE/EPERM/EBUSY retry once and
succeed. The exemption is removed and its allowlist entry with it.

One old assertion is deliberately not carried over: it checked the retryable
errnos were expressed as a Set rather than an inline literal. That is a shape
check with no runtime signature; the behavioural tests fail if the code reverts
to the old inline check, which is the regression it was really guarding.

The #3057 lock-body tests move into that same file rather than a new one, which
is what lint-test-file-count asks for and puts every acquireStateLock test in
one place.

* fix(#3057): surface an indeterminate staleness check to its callers

An isolated review caught an inconsistency inside this wave. Two of the three
"add the distinguishing signal" fixes wire through to something a user sees:
git base-branch writes an unverified-fallback diagnostic to stderr, and an
unverifiable worktree surfaces as a W020 finding. The third set
staleCheckIndeterminate on readVerificationStatus's result and nothing read it.

A signal nobody consumes leaves the fail-open exactly as silent as before: the
staleness check could fail and the operator saw precisely what they would see
if the answer were genuinely "not stale". That is the defect this issue exists
to remove, so it is not defensible as scaffolding when its two siblings in the
same change already wire through.

All five callers now surface it, each through the channel it already had rather
than a mechanism imposed uniformly: phase complete adds it to its existing
warnings array and, on the blocked path, as an additive note on the error text;
init and roadmap carry it as a field on output they already emit; the UAT
report carries it without ever gating passed/blockers; workstream inventory
takes an injectable writeDiagnostic mirroring the git base-branch idiom,
because its return shape had nowhere to hang a per-phase field without
rippling the builder's types.

The routing decision is unchanged everywhere. What changes is only that a
caller and an operator can now tell a failed check from a completed one.

That diagnostic carries structured meta rather than being asserted by regex —
the default still writes only the human message to stderr, but tests assert
phaseDir and reason by value. Two earlier assertions in this branch were
converted the same way; this was the last raw-text assertion left.

Also records a scope correction: the completePhaseCore guards now compare
stateReplaceField's result to the body instead of testing truthiness, so a
field whose substitution produced identical text no longer reports as updated.
That is a real behaviour fix, not the signal-only change this file was
described as carrying, and its tests cover both the changed and unchanged
cases.

* test(#3057): bound two heavy subprocesses for a loaded bench, not an idle one

The remote matrix surfaced three failures unrelated to this branch's changes.
All were bad tests, and a re-run would have hidden every one of them.

The reviewer-flags parse block bounded bash -> node -> a full gsd-tools cold
start at 5 seconds. On a bench running thirty thousand tests in parallel that
is not a hang, it is a busy machine. Raised to 30s, matching the convention
sibling suites already use for script invocations, with a comment saying what
the budget covers so nobody tightens it back. Two further copies of the same
5-second spawn in the same file had the identical defect and are raised too —
they were not in the failure report, but they will be next time.

The fragment-propagation test bounded npm run regen:derived — a full build plus
eight generators, the heaviest subprocess in the suite — at five minutes, and
node22 was killed near the end. The captured output proves it: every generator
had written its files and gen:install-tree had emitted all fifteen runtimes
before the kill. Raised to fifteen minutes.

That failure read as `null !== 0`, which says nothing. status null means killed,
not a non-zero exit, and the two want different responses: one is a timeout to
size correctly, the other is a real build break. The assertion now distinguishes
them and names the signal.

Neither test's assertions were weakened and no retry was added. A retry here
would suppress exactly the signal the timeout exists to produce.

* test(#3057): capture fd 1 through the mock tracker, not a raw reassignment

The phase suite reported zero test results on both lanes while running for five
and a half minutes and exiting 1. No assertion text, no stderr, four events for
the whole file: enqueue, start, dequeue, complete. That shape is not a failing
assertion — it is the runner being unable to read the child at all, because it
parses its event stream from the child's stdout.

The cause was the capture helper reassigning fs.writeSync directly. Proven
rather than assumed: a standalone probe patched fs.writeSync and called
process.stdout.write, and the interception fired only when fd 1 resolved to a
FILE, not when it was a pipe. The remote runner captures the event stream to a
file, so a helper that was invisible against a pipe swallowed the reporter's own
output on the bench. That is also why the two sibling suites wired the same way
in this change pass cleanly — they use the mock tracker, the seam io.test.cjs
established for this exact function.

The helper now uses t.mock.method with an explicit restore after each call, so
teardown belongs to node:test rather than a second hand-rolled implementation,
and the interception cannot outlive the one synchronous call it wraps even if
that call throws. Ten call sites thread the test context through; three test
callbacks gained the parameter they lacked.

The three B3 tests are untouched — same assertions, same fault injection. Only
how the context reaches the helper changed.

* test(#3057): capture phase-complete output from a subprocess, not fd 1

Two attempts to make in-process fd-1 interception safe both failed on the
bench. The suite reported zero test results on either lane while exiting 1 —
four events for the whole file — because the runner parses its event stream
from the child's stdout, and process.stdout.write routes through fs.writeSync
whenever fd 1 resolves to a file, which is how the runner captures. Patching
that seam anywhere in a file can therefore destroy the file's own reporting,
and tightening the window only moved the runtime from 326s to 125s without
recovering a single event.

So the interception is gone rather than tuned. The helper now spawns gsd-tools
as a real subprocess and reads stdout the way the OS already gives it to us,
which is what the rest of the suite does. It asserts the command succeeded
before parsing, so a genuine failure can no longer present as a JSON parse
error.

The two fault-injecting tests could not survive that move as written: a
subprocess cannot see a mock installed in the parent. Instead of reinstating
the interception they now produce the fault on disk — the summary artifact is
created as a dangling symlink, so the staleness check's real statSync throws
inside the child. That is a more honest fixture than a mock in any case, since
it is a condition a user's tree can actually be in. Skipped on Windows, matching
the existing symlink precedent in the write-guard suite.

Three further call sites turned out to depend on parent-process writeFileSync
mocks the subprocess could not see. Those call the CJS function directly, which
is what they always wanted — they never needed stdout at all.

* fix(#3057): one name for one signal, one encoding for one distinction

Standards review found four things this branch introduced, all of them
inconsistencies with itself rather than with the repo.

One upstream bit reached its consumers under three names —
verification_stale_check_indeterminate in two modules, the same value with
"stale" dropped in a third, and stderr only in the fourth. Standardised on the
long name wherever it is a field. The workstream inventory keeps its stderr
channel, since its return shape has nowhere to hang a per-phase field without
rippling the builder's types, but it now says the same word for the same thing.

worktree-safety encoded one three-way distinction two ways in a single file: a
named union for a finding's kind, and boolean|null for an inventory entry's
existence. The second is now a named union too.

Two assertions matched human prose because the blocked and non-blocked
completion paths carried no typed field for the signal. Both now assert typed
values. The first round of this fix added the field but left the regex beside
it, which is the banned pattern sitting next to its own replacement; the second
removed it and added an assertion on the reason enum so nothing was lost.

The remaining two were reasoned away before being fixed, and both reasons were
bad. "No typed surface exists" is the condition CONTRIBUTING says to fix by
adding one — it took three lines. "The file already does this dozens of times"
is not licence to add instance number thirty-one; a convention that violates a
documented rule is debt, not precedent.

Vocabulary differing across DIFFERENT modules is left alone: CONTEXT.md rejects
a single shared result envelope, so per-module shapes are precedented, and a
baseline smell does not outrank a documented standard.

A census of every line this branch adds to a test file now finds no regex or
substring assertion on produced prose: 87 strictEqual, 25 ok (all non-empty or
shape guards), 12 equal, 3 throws (all typed err.code predicates), 3
deepStrictEqual, 2 notStrictEqual.

7e1004d89e test(#3056): add the in-process fault-injection adapter, and normalize execGit's shape (#3077)
* refactor(#3071): normalize execGit's call and result shape, unify ExecGitFn

ExecGitFn was declared four times. Three were hand-copies of one signature and
two of those were wrong: they typed exitCode as number|null when _spawnResult
returns `result.status ?? 1` and can never yield null, weakened signal from
NodeJS.Signals to string, and widened error from Error to unknown. Only
verification.cts got it right, via `typeof execGit`.

The root cause was a missing export: SpawnResultOutput was declared without
`export`, so no other module could name the return type of execGit. Three
authors independently hand-copied it instead. Exported now.

Normalizing the type alone would have left the pressure that caused the
divergence, so the function is normalized on both sides. It now ACCEPTS every
call its consumers make — worktree-safety's declaration could not express an
env-carrying call at all — and RETURNS every result code they need: timedOut
moves into _spawnResult, so execGit, execNpm and execTool all carry it and the
one extension that justified a separate type disappears. All four sites are
now `typeof execGit` with nothing left to restate.

timedOut reuses the existing isSpawnTimeout predicate introduced by #3050
rather than re-deriving it. That predicate checks error.code === 'ETIMEDOUT'
only; the signal === 'SIGTERM' conjunct was deliberately dropped there because
Windows does not reliably report SIGTERM and requiring it risks a false
negative. There is no false-positive risk, and a test proves it: an
externally-delivered SIGTERM leaves error null, so it is still not reported as
a timeout.

No dead null-checks surfaced. Every exitCode comparison in the two affected
modules is === 0, !== 0 or === 128 — never a null guard — so the nullable
declaration had never been written against.

Closes #3071

* test(#3056): add the in-process fault-injection adapter

Adds tests/helpers/faulty-deps.cjs — makeFaultyGit() and withFaultyFs() — so a
module's error branch can be driven deterministically and its degraded verdict
asserted, instead of a counter-test that only proves the call did not throw.

makeFaultyGit returns a value structurally assignable to `typeof execGit`, so
one stub satisfies all four seams that the #3071 normalization collapsed into
that single shape. A parity test drives the same stub through a real injectable
entry point in each of worktree-safety, git-base-branch, worktree-base-ref and
verification; it fails the moment any of them re-grows its own shape.

Faults are scoped rather than global — by argv predicate and by call ordinal —
because a fault adapter that faults everything looks like it works and proves
nothing, and because verification.cts's two-call error handling needs to fault
the second call only. Invocations are recorded so a test can assert an exact
call count.

The timeout fault carries error.code === 'ETIMEDOUT', and a test asserts the
real isSpawnTimeout predicate matches it, so the fixture cannot drift from the
production definition of a timeout. A companion test asserts an externally
delivered SIGTERM with a null error is still NOT reported as a timeout — the
false-positive guard for #3050's dropped conjunct.

withFaultyFs restores in a finally so a throwing body still restores, patches
only the named methods, and nests without clobbering an outer saved original.
It never uses chmod: that no-ops under root, so the test would pass with zero
coverage in root Docker/CI.

The adapter is in-process via deps only. The Phase 1 process seam is documented
as deliberately not a fault-injection surface — it cannot distinguish an
injected timeout from a genuine bench OOM and would retry it.

* fix(#3071): route the last two timeout checks through the shared predicate

An isolated review found this branch had normalised the timeout verdict but
left two callers still hand-rolling the fragile version of it.

check-command-router's runBoundedShell computed `timedOut: r.signal ===
'SIGTERM'` while the correctly-derived `r.timedOut` sat on the same result
object. graphify's execGraphify branched on `result.signal === 'SIGTERM'`, with
a comment asserting the very premise isSpawnTimeout exists to reject.

Both fail in both directions. On Windows a genuine timeout is not reliably
reported as SIGTERM, so the guard silently fails to fire — the false negative
#3050 was raised for. And an externally-delivered SIGTERM is not a timeout at
all, so the check also fires when it should not; isSpawnTimeout avoids that
because `error` is null in that case and it keys on error.code.

Both now read the derived `timedOut`, and graphify's comment states the actual
rule instead of the fragile assumption.

Also replaces a vacuous test: "execGitDefault now accepts env" never called
execGitDefault (it is unexported), called execGit — whose signature already
accepted env before this branch — and asserted only that exitCode was a
number, which would pass whether or not the change under test existed. It now
proves env reaches the child by asserting `git var GIT_EDITOR` returns the
injected sentinel.

* test(#3071): make the graphify timeout fixture faithful to a real timeout

The remote matrix failed on both Linux lanes: graphify's "returns exitCode 124
on timeout" got 1 instead of 124. The fixture was wrong, not the production
change.

It stubbed spawnSync as { status: null, signal: 'SIGTERM', error: undefined }.
That is not a timeout. A real spawnSync timeout also sets error.code
'ETIMEDOUT'; a SIGTERM with no error is an externally delivered signal — a
kill. The old `result.signal === 'SIGTERM'` check accepted it as a timeout,
which is the false positive the shared predicate exists to reject, so this test
was locking that bug in rather than guarding against it.

The fixture now carries a real ETIMEDOUT error and all three original
assertions pass unchanged. A counter-test is added alongside it: an externally
delivered SIGTERM with no error must NOT be reported as a timeout. That is the
assertion whose absence let the false positive live.

Swept every SIGTERM/SIGKILL stub under tests/ for the same unfaithful shape.
No other instance: the worktree-safety, worktree-base-ref and commit-staging
fixtures already set ETIMEDOUT, and the remaining hits are either deliberate
external-kill tests or feed code that never consults timedOut.

Two sites keep their own signal check deliberately and are NOT changed:
capability-source.cts:1301,1386 fail closed on ANY abnormal termination, which
is correct — reading timedOut there would stop it failing closed on a kill and
let it parse stdout from a killed process. Their reason strings, and
check-latest-version.cjs:115, label any signal as "timed out", which is
imprecise wording over a correct verdict, not a silent failure.

8c3d934a90 refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete) (#1295)
* refactor(#1294): T-final — delete the core.cjs re-export spine (epic #1267 complete)

After T0–T6 nothing imports core, so retire the spine and its scaffolding:
- delete src/core.cts (and the gitignored gsd-core/bin/lib/core.cjs artifact;
  remove its .gitignore + eslint-ignore entries)
- delete scripts/lint-core-spine-imports.cjs + its allowlist; drop it from the
  package.json lint:ci chain
- regenerate docs/INVENTORY-MANIFEST.json (drops the core.cjs surface)
- sweep stale references: CONTEXT.md glossary back-compat clauses (spine retired,
  callers import the leaf directly), planning-config.md CONFIG_DEFAULTS owner,
  and false present-tense core.cjs claims in leaf-module docstrings

The ADR-857 decomposition is complete: the former Core god-module is fully
dissolved into its leaf modules; no re-export spine remains. No behaviour change.

Closes #1294

* fix(#1294): migrate the computed-path core.cjs importers the literal grep missed

bin/install.js used require(path.join(_gsdLibDir, 'core.cjs')) (a computed
path, and bin/install.js was never in the convergence lint's scan roots), and
~8 test files referenced core.cjs via path.join/readFileSync/existsSync/FILE_ARG
forms the literal-string migration grep missed. Route install.js's symbols to
their leaves (RUNTIME_PROFILE_MAP->model-catalog, resolveTierEntry/EFFORT_SET->
model-resolver) and repoint/adjust the test references to the leaves. Recovers
the 161 'Cannot find module core.cjs' failures from the spine deletion.

48d9cec6fe refactor(#1268): re-home core re-export-spine squatters + migration-convergence lint (#1272)
Re-home the 6 implementation functions squatting in the core.cjs re-export
spine (ADR-857) into the modules whose interface they belong to, with core
re-exporting them BY REFERENCE so all 32 callers + the shim-identity tests
keep resolving unchanged:
- worktree-safety: resolveWorktreeRoot, pruneOrphanedWorktrees
- git-base-branch (broadened to the Git Query Module): gitWorktreeInfoInternal
- agent-install-check (new leaf): getAgentsDir, checkAgentsInstalled
- delete the _resetRuntimeWarningCacheForTests wrapper; consumers use a
  shared resetRuntimeWarningCaches() helper in tests/helpers.cjs

Add scripts/lint-core-spine-imports.cjs (migration-convergence lint with a
30-importer allowlist, wired into lint:ci) so the staged spine retirement
provably converges: CI fails on any new ./core import. Register the new
generated agent-install-check.cjs in eslint-ignore + .gitignore +
INVENTORY-MANIFEST.json.

No behaviour change. First tranche (T0) of epic #1267.

e9f9ae49c8 fix(#1146): single base-branch resolver across forking workflows (#1198)
* fix(#1146): single base-branch resolver across forking workflows

Replaces duplicated per-workflow bash detection that silently fell through
to :-main on repos where origin/HEAD is unset (git init+remote add+fetch
without set-head, most CI checkouts, many worktrees).

New CJS module git-base-branch.cjs exposes `gsd_run query git.base-branch`
with full precedence ladder: git.base_branch config override → origin/HEAD
symref → git remote show origin (authoritative) → local branch presence →
"main". All git subprocesses bounded with timeouts; degrades gracefully.

Wires execute-phase, quick, ship, complete-milestone, and pr-branch to the
single resolver. Removes 14 lines of duplicated detection bash across the
five workflows.

Includes 7 behavioral tests covering the full precedence ladder including the
key regression case (master repo, origin/HEAD unset → must return "master",
NOT "main") and an anti-regression guard that fails if any workflow
re-introduces the :-main/:-master fallback pattern.

handle_branching (execute-phase.md) and step 2.5 (quick.md) are extracted

Adding a || fallback ladder (git symbolic-ref then echo main) keeps the
unified resolver as primary in real workflows while letting the test harness
succeed without gsd_run defined.

Also propagates updated runtime-launcher preamble to pr-branch.md (added in
origin/next MemPalace PR) and regenerates workflow-size-baseline.json.
