fa41bfec5c enhance(#3942): the emitted-drift ack is PR-lifetime data — move it to a commit trailer (#3954)
* test(#3942): failing-first suite for the emitted-drift ack commit trailer

Binds 37 input classes from the phase test matrix to the behavior ADR-3942
specifies, before any of it exists. Stubs return benign empty values rather
than throwing, deliberately: several rows assert that something DOES throw
(cap overflow, uncomputable commit range), and a throwing stub would turn
those green for the wrong reason and destroy the red.

The two rows that carry the design's load:

- merge-base semantics. The range is $(git merge-base base HEAD)..HEAD, not
  base..HEAD, because changedPaths comes from `git diff base...HEAD` (three
  dot). Two-dot would let the ack set and the change set disagree about which
  commits are this PR's. The fixture forks a topic branch, puts a trailer on
  each side, and asserts only the topic-side trailer is in range.

- fail-closed on an uncomputable range. With fragments a depth-1 checkout
  passes VACUOUSLY, every fragment reading as brand-new. With trailers the
  range cannot be computed at all, and returning an empty set would silently
  disarm the gate, so it must throw. The fixture builds a genuine shallow
  clone rather than simulating one.

Also covers the self-inflicted case: this change's own documentation quotes
the trailer syntax, so an example landing at the end of a commit message would
arm a live acknowledgment keyed on the literal placeholder text. Keys carrying
angle brackets or whitespace are rejected.

Authored per the phase artifacts 40-design.md and 50-test-matrix.md.
Not yet run on the remote runner — this commit exists to be tested.

* chore(#3942): move the emitted-drift ack to a commit trailer

Implements ADR-3942, superseding ADR-2719 section 3 and its #2789 amendment.
Sections 1, 2 and 4-7 are retained: the conservation law is unchanged, only the
storage of its escape hatch moved off the working tree.

An acknowledgment explains one PR's ripple, and the moment that PR merges the
ripple is in the base, so it can never clear anything again. It was stored in
permanent shared state anyway, and every consequence of that mismatch had to be
built and then maintained. The chain is #2789 -> #2914 -> #3078 -> #3842 ->
#3823 -> #3875, each fix generating the next defect, ending in a scheduled
sweeper whose own first PR could not merge itself.

Added
  parseAckTrailers + renderAckTrailer (pure) and readAckTrailers (IO shell),
  reading Emitted-Drift-Ack-Hash: / Emitted-Drift-Ack-Growth: trailers over
  the merge-base range. tests/emitted-ack-trailer.test.cjs, 37 cases, written
  failing-first and confirmed red before any of this existed.

Changed
  diffEmitted takes two structurally distinct key-space maps instead of one
  shared paths map. That closes a latent defect: the spaces were separated by
  convention only, so a growth key satisfied a hash lookup by naming
  coincidence. staleAcks now reports which space a key was declared in.
  REMEDIATION teaches the trailer, per space, with its example rendered through
  renderAckTrailer so the taught grammar cannot drift from what the parser
  accepts.

Removed
  the sweep workflow, the guard-no-ack-on-next job, the standalone linter and
  its lint:ci entry, the fragment directory and its three spent fragments, the
  legacy single-file union, and the baseAck/spentAcks mechanism -- spentness is
  now structural, not computed.

Two range properties carry the design and are pinned by tests rather than
asserted: the range is merge-base scoped, matching git diff base...HEAD, so an
already-merged trailer is out of range by construction; and an uncomputable
range throws instead of reading as zero acknowledgments, which is the inverse
of the fragment guard's vacuous pass.

Three deliberate observable changes, each disclosed in the changeset: the
unread runtime field is gone, the legacy file is no longer read, and cross-space
excusal no longer works.

Ten open PRs carry fragments and will meet a modify/delete conflict. Measured
before landing and accepted deliberately; the one-line migration is in the PR
body.

Verified: lint:ci exit 0. Remote runner to follow on this exact sha.

Refs #3942

* fix(#3942): silent trailer collapse, lost coverage, and an unbounded cap

Six findings from the orthogonal review round, all fixed in place.

BLOCKER -- two trailers of the same name on one commit collapsed silently.
readAckTrailers built `separator=1d` where git needs `separator=%x1d`: the
`separator=` value inside a %(trailers:...) placeholder is itself a
pretty-format string, so the bare hex was emitted as two literal characters
and the split on \x1d never matched. Two same-name trailers therefore joined
into one value with errors empty -- the first reason absorbing the second
entry's key. Silent truncation, the exact class MAX_ACK_TRAILERS throws to
prevent. Confirmed with od -c against real git output before and after.

The failing-first matrix did not catch it because its "both spaces coexist"
row uses Hash plus Growth -- different trailer NAMES -- so the value separator
was never exercised. Two regression tests now cover same-name trailers
directly.

Coverage recovered: normalizeAckReason and INVISIBLE stayed on the live path
via parseAckTrailers but lost every test when the old suite was pruned. Back
under test against the current surface -- all six invisible codepoints
individually, whitespace collapse, trim, CRLF, and two seeded fast-check
properties. Dropping any single codepoint now fails.

MAX_ACK_TRAILERS counted raw trailers before de-duplication, so one trailer
carried forward across rebased commits counted once per commit and could throw
on a legitimate branch. Now counts distinct entries; 100 identical repeats
dedupe to one.

diffEmitted validated baseline, current and changedPaths but not the new
ackHash/ackGrowth, so a bad shape raised an unhandled TypeError instead of an
error verdict -- the same defect shape this file documents for #2778.

Docs: CONTRIBUTING and TESTING-SUITES were rewritten only in their first
sections; the later passages still taught fragments, git rm and the deleted
guard, contradicting the new text directly above them. Finished.

Also extends lint-removed-but-needed to exempt docs/adr and docs/research.
That gate fails on any docs mention of a file deleted in the same diff, which
makes it impossible to document a deletion in the PR performing it -- an ADR's
whole job is naming what it retired. Exemption is narrow and comes with a test
proving the gate still fires for a live consumer elsewhere under docs/. A
guard that cannot fail is worse than no guard. Maintainer-approved.

CONTEXT.md names the retired machinery by role rather than by filename: its
generated projection lands in docs/, which that gate does scan.

Adds docs/how-to/acknowledge-emitted-drift.md. The required docs set is
Reference and Explanation, so the task quadrant can be empty with every gate
green -- and this change has a real multi-step journey, including the fragment
migration ten open PRs now need.

lint:ci exit 0.

Refs #3942

* docs(#3942): correct the duplicate-trailer rule in CONTRIBUTING

Both axes of the code review independently flagged the same passage, without
seeing each other's output.

It claimed two declarations of the same key are always "a hard, loudly-reported
error, not a silent last-wins". That is only half true, and the missing half is
the one contributors hit: identical declarations -- same key, same reason --
dedupe silently, because a trailer legitimately survives a rebase and reappears
on every rebased commit. Failing there would red a branch for doing nothing
wrong, which is exactly why the dedup exists.

Only a same-key/different-reason pair errors, and that one is a genuine
ambiguity about which explanation holds.

As written, the paragraph told a contributor that a rebase-carried trailer
breaks the gate -- the opposite of the behavior. CONTEXT.md's parallel entry
already stated it correctly; this brings CONTRIBUTING into line.

Doc-only, root-level markdown.

b42cb4fb29 fix(#3597): count scenario expectation failures in the QA gate, and fix the workstream scope split it exposed (#3607)
* fix(#3597): count scenario expectation failures in the QA ratchet gate

buildReport counts totals.violations as oracle violations PLUS scenario
expectFailures, but collectFindings read only step.violations. A scenario
whose declared expect failed therefore produced ok:false and violations:1
in the report while the ratchet printed "0 violations" and exited 0.

multi-workstream has failed that way on every CI run since 2026-08-10,
when #3217 (PR #3318) made computeProgressPercent withhold a percentage
whose scope is not COMPLETE. The walk detected the change the day it
landed; nothing was listening.

- collectFindings returns a third bucket, expectationFailures, carrying no
  fingerprint so it can never be baselined or acked away
- both modes of main() print and gate on it; the summary line reports it
- guard runMain(main) behind require.main === module, so the QA suite can
  require the script to test collectFindings without running a real walk
  (that import side effect is why the gate logic had no test)
- multi-workstream now asserts the true contract: phase_scope unreadable
  and percent null, per ADR-3180 7.6 rule 4
- the perturbation test asserts scenario ok, closing the test-side half

Closes #3597

* fix(#3597): resolve the milestone window against the active workstream

listMilestonePhaseDirs defaulted its ws option to null. planningDir
treats undefined as "resolve the ambient workstream" and null as
"force the project root", so that default suppressed the ambient
resolution every other planning-path read uses.

All 18 call sites derive phasesDir ambiently via planningPaths(cwd),
so the counts came from the workstream while the milestone window came
from the root .planning/ROADMAP.md — the exact numerator/denominator
scope split ADR-3180 7.6 rule 3 forbids. workstream create migrates
that root roadmap away, so the read threw and scope stayed UNREADABLE,
and rule 4 then correctly withheld the percentage.

Proof: with a workstream tree byte-unchanged, copying its own ROADMAP
to the project root flipped --ws alpha progress from
phase_scope:unreadable/percent:null to complete/100.

This is the defect the loop QA walk was pointing at all along; the
scenario expectation is restored to percent:100 rather than bent to
match the bug.

- pass ws through as undefined so ambient resolution applies
- multi-workstream asserts phase_scope complete + percent 100
- regression test in completion-ratio-scope-withholding covers a
  workstream-only project with no root ROADMAP
- replace the vacuous require.main test: runMain defers through a
  promise, so the in-process timing check passed against the unguarded
  file too; a child-process spawn now observes the guard for real
- tie the oracle-violation test to expectationFailures, and cover the
  absent-key, multi-scenario and zero-step report shapes in parity
- flatten scenario-authored strings before rendering them into the
  step summary and CI logs (forged markdown / ANSI injection)
- widen the scenario contract assertions past perturbation-* so
  multi-workstream is actually covered test-side

Closes #3597

* fix(#3597): flatten scenario-authored strings on the CI-log output path

The step-summary path already routed findings through flattenUntrusted;
the check-mode NEW-smell and STALE-entry console.error blocks, and the
repro line in both printers, still interpolated raw.

detail carries a scenario-authored expect[].path verbatim, and
reason/scenario/id come from contributor-authored baseline and ack
fragments validated only as non-empty strings. A crafted path could
print a forged summary line into the CI log directly above the real
one, plus ANSI repaint and unbounded length.

Exit codes are unaffected — this is log spoofing, not gate bypass.

* fix(#3597): refuse to archive on an unreadable milestone window; close review gaps

Resolving the milestone window against the active workstream can leave
the window UNREADABLE when that workstream has no ROADMAP of its own.
getMilestonePhaseFilter throws, the window degrades to a pass-all
fallback, and milestone complete would then move every phase dir --
breaking the guarantee stated at the archive site that no out-of-window
directory is touched.

milestone complete now refuses to archive when the window is UNREADABLE
and reports the refusal; --dry-run previews the same refusal from the
same shared derivation.

The guard is scoped to UNREADABLE, not to every non-COMPLETE scope. A
broader condition regressed ordinary root projects: the QA walk caught
milestone-rollover leaving 01-parser on disk, which then tripped the
#1447 abort in phases clear. UNSCOPED and TRUNCATED are pre-existing
classifications and keep their existing behavior.

Review fixes:
- the workstream regression test asserted complete/100 but its fixture
  wrote no workstream STATE.md, so it resolved unscoped/null and the
  test failed; it now asserts a milestone and genuinely fails-first
- the parity test hand-supplied totals.violations, hardcoding the very
  formula under test; at least one case now goes through the real
  buildReport
- drop a vacuous qa-report.json assertion (jsonOut defaults to null, so
  no report is written by either shape)
- buildRepro emitted a repo-relative binary path after cd-ing into a
  temp project, so every repro died with MODULE_NOT_FOUND; it now
  resolves an absolute path
- flattenUntrusted truncated the repro to 300 chars, handing reviewers a
  command that looks complete and is not; length capping is now opt-out
  for repro while newline/control/backtick stripping still applies

5fd5c81042 test(#3055): add the process seam so a subprocess timeout is expressible as data (#3066)
* test(#3055): add the process seam and route runGsdTools through it

Adds tests/helpers/process-seam.cjs — runNode/runGit/runHook over spawnSync,
each returning a typed discriminated union
{ outcome, exitCode, stdout, stderr, timedOut, signal, killed, code }.
Every call is timeout-bounded; there is no unbounded path.

runGsdTools becomes an adapter over the seam. Its legacy
{ success, output, error, exitCode } shape and retry-once-on-kill behaviour
are preserved byte-identically, so none of its 136 caller files change.

Outcome discrimination was corrected against probed runtime behaviour rather
than assumption: a timeout and a maxBuffer overflow are identical on both
status (null) and signal (SIGTERM), and differ only by code (ETIMEDOUT vs
ENOBUFS). Overflow is therefore classified before timeout. This fixes a live
defect — the previous isKilled() treated an overflow as a kill, retried it for
a second full 60s run, and then reported "host OOM or scheduler contention"
for a child that had merely printed too much.

Also widens the ESLint tests glob from tests/**/*.test.cjs to tests/**/*.cjs,
which brought 31 previously unlinted shared helpers under the same rules their
sibling test files already obey, and fixes the 5 violations that surfaced —
including a bare npm invocation without shell:true in
tests/helpers/emitted-runtime.cjs (DEFECT.WINDOWS-TEST-PORTABILITY), now
routed through the existing portable runNpm helper.

* test(#3055): migrate every local spawn wrapper onto the process seam

Replaces the spawn body of all 25 local runHook/runGuard/runGate definitions
with a call to tests/helpers/process-seam.cjs. Each wrapper keeps its name,
parameter list, return shape and post-processing (JSON parse, ANSI strip, env
sanitising, field extraction) — only the spawn mechanism changes, so no test
assertion moves.

The 4 bash-driven wrappers use the seam's explicit `interpreter` option rather
than a fourth primitive; it is explicit rather than inferred from the file
extension, because guessing an interpreter from a path fails silently when a
script's name does not match its shebang.

Seven wrappers were previously unbounded and now carry an explicit timeout
sized to what each actually runs, not the seam default. Two of those seven
(gsd-write-guard, lint-docs-command-form) were absent from the issue's
inventory entirely and were found by scanning after the migration.

Adds the CONTEXT.md `### Process seam` glossary entry and a CONTRIBUTING.md
reference section covering the three primitives, the discriminated union, and
the two rules the seam enforces.

Scope disclosure recorded in the phase design notes: the issue scoped three
identifier names. A scan for local helpers that spawn AND return the spawn
result finds 113 across 82 names, 71 of them unbounded, plus 122 unbounded
direct git call sites. This change bounds 25 of those. The remaining surface
is the same defect class and is NOT closed by this PR.

* fix(#3055): classify an externally-killed child as KILLED, not EXITED

Blocker found in this branch's own diff, independently confirmed by an
isolated reviewer.

A child killed by an external signal — a genuine bench OOM kill — makes
spawnSync return { status: null, signal: 'SIGKILL' } with NO .error field.
The seam's "no error implies EXITED" rule therefore classified it as a clean
exit, and runGsdTools returned { success: false, exitCode: 1 } without
retrying. That silently defeated the #969 kill-discrimination for precisely
the case it was built for: the old isKilled() fired on `signal != null`,
retried once, then threw a labelled resource-starvation error. A real OOM
would have been reported as an ordinary assertion failure.

Adds a fifth outcome, KILLED, for "no error but a signal is set", and makes
the adapter retry on TIMED_OUT or KILLED — reproducing the old
`killed || signal != null || code === 'ETIMEDOUT'` condition exactly.
SPAWN_FAILED still does not retry (matching the old behaviour, where signal
was null). BUFFER_OVERFLOW still does not retry, which remains a deliberate
divergence: the old code retried it because signal was SIGTERM, burning a
second 60s run on a child that had merely printed too much.

All five outcomes verified against the live runtime rather than assumed:
SIGKILL -> killed, exit 0/7 -> exited, timeout -> timed_out (ETIMEDOUT),
>1MB stdout -> buffer_overflow (ENOBUFS).

* fix(#3055): address standards-review findings on this branch

Three findings from the standards axis of the review, all in this branch's
own diff.

The CONTEXT.md glossary entry this branch introduced was already stale on the
branch's own last commit: it enumerated a 4-member OUTCOME while the code had
5, because the KILLED fix did not update it. That is precisely the drift the
"module changes update Domain-terms" gate exists to catch, so the entry now
lists all five and explains KILLED.

api-coverage-gate-e2e compared an outcome against the raw string 'exited'
rather than OUTCOME.EXITED, the only such outlier; the enum is now imported
and used. A sweep for the other four outcome literals found no further
comparison sites.

Three call sites hand the literal bash flag '-c' to the seam's first
parameter, which the JSDoc described as an absolute script path. Rather than
add a fourth primitive, the contract is corrected to match reality: the
parameter is renamed `target` and documented as the first argv element handed
to the interpreter — normally a script path, but for an interpreter invoked
with an inline program it may be that interpreter's own flag. No behaviour
change.

* test(#3055): assert the cross-platform timeout contract, not the macOS one

The remote runner failed on both Linux lanes (node 22 and node 24, identical)
while the same tests passed locally on macOS. Two assertions encoded a
platform-specific behaviour as a cross-platform guarantee.

When spawnSync times out, macOS preserves the child's partial stdout/stderr;
Linux discards it and returns empty strings. Verified on node v26.5.1 both
ways. The seam passes through whatever spawnSync hands it and cannot
manufacture output that was discarded, so the production code was correct —
the tests were wrong.

Both tests now assert the guarantee the seam actually makes on every
platform: outcome TIMED_OUT, timedOut true, and stdout/stderr always being
strings rather than undefined or a Buffer. The partial-content assertions are
retained behind an explicit process.platform === 'darwin' guard so the macOS
coverage is not lost, and the first test is renamed to say what it now
guarantees.

This is the failure mode the remote matrix exists to catch: local macOS
verification would have shipped it.

* fix(#3055): classify a failed spawn as SPAWN_FAILED, not a timeout

Windows CI caught two defects the Linux matrix could not.

tests/context-predicates-query.test.cjs passes a 32K-char argv value. On
Windows that exceeds the argv limit and spawnSync fails with code
ENAMETOOLONG, signal null, status null. The seam's fallback rule — "otherwise,
status === null implies TIMED_OUT" — swallowed it, so the adapter retried a
spawn that can never succeed and then threw the resource-starvation error. The
old isKilled() returned false for that shape and returned an ordinary failure
result.

TIMED_OUT is now identified positively: code === 'ETIMEDOUT' OR signal is set.
Anything else carrying an error is SPAWN_FAILED, which covers ENAMETOOLONG,
E2BIG, EACCES and ENOENT alike. The signal clause is what keeps a platform
whose timeout errno differs classified correctly, so the greedy catch-all is no
longer needed.

The second defect is a contract regression I introduced and had claimed
otherwise. That same test asserts `typeof r.exitCode === 'number'`, and
toLegacyShape was returning null for BUFFER_OVERFLOW and SPAWN_FAILED, so the
assertion failed on type. The old code returned `err.status ?? 1` on every
non-retried failure path. The adapter now returns 1 again for both, and the
comment claiming "never coerced to exitCode:1, unlike the pre-seam helper" is
retracted: the seam keeps the richer truth (exitCode null plus a distinct
outcome), the legacy adapter keeps the old numeric contract its callers
actually depend on.

Verified on this host: a 4MB argv yields E2BIG -> SPAWN_FAILED; ENOENT ->
SPAWN_FAILED; timeout -> TIMED_OUT; >1MB stdout -> BUFFER_OVERFLOW; SIGKILL ->
KILLED; clean exit -> EXITED.

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.

* 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.

* 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.
