timothyandClaude Opus 5 090a29db3d fix(887): two defects the FIX introduced, found by attacking it rather than reading it
Both were measured, not reasoned, and both are the shape this repo keeps recording — the
fix round introducing an adjacent defect, and a unit test using a simpler input shape
than the real file has.

`npm test -- --run && echo ok || true` reported NO suppression. `&&`/`||` chain across a
whole list, so when the suite fails the `&&` right-hand side is skipped and the `||`
right-hand side runs: the list exits 0 and the suite's failure is swallowed even though
the `||` is not adjacent to it. The detector looked only at the separator IMMEDIATELY
after the suite segment. It is now scoped to the `;`-delimited list, which also catches a
backgrounded `npm test &` (status never awaited) and `( npm test ) || true`. A `;` ends
the list and resets, so `npm test; other || true` stays clean — that `||` is about the
other command.

`--exclude 2 > log` reported `['--exclude']`, losing the filter's own value: stripping
redirections as a PRE-PASS let the file-descriptor rule claim the `2` before the flag
could. Redirections are now consumed inside the walk, after flag values are taken.

The mutant battery grew from 17 to 24 and is 0-missed. The `docs/guard-inventory.md` row
now states the count and, explicitly, the grading: exactly ONE of the 24 is declared in
`mutation_manifest.py` and re-executed every suite; the other 23 were witnessed by hand
and are NOT standing. That is the same footing `pageSizeCallSites.guard.test.ts` states
for its nine, and saying so is the difference between evidence for the reach and a claim
of a per-run proof.

timothyandClaude Opus 5 a4df8f7958 fix(887): the gate must be REAL, not merely present — two cold reviews' findings
Both independent reviews (Codex GPT-5.6 cross-family, and a cold Opus agent in an
isolated worktree) returned BLOCKED. Both independently confirmed the CI path itself is
sound — neither found a route that publishes an image on which the suite never ran — so
every finding is about the guard's reach, plus one factual error in the prose.

THE STRUCTURAL ONE. The guard asserted a `needs:` edge EXISTS, never that it is load
bearing. Since this change deletes the in-image run, that edge is the only remaining
layer, so `continue-on-error: true`, `if: false`, a job-level `if:`, `npm test … || true`,
a pipe into `tee`, and `set +e` each certified a publish over a red suite with every
assertion green. `test_the_gating_suite_run_is_NOT_ADVISORY` closes all six.

A filter written into `web/package.json`'s script body was invisible at the call site:
`"test": "vitest --exclude x"` with a workflow saying `npm test -- --run` is a filtered
gating run reading as clean — the removed defect, one level down. `vitest_scripts()` now
derives each script's own narrowing arguments and `suite_args` prepends them.

PARSER REACH, every case measured rather than argued. `shlex.split` yields `lint&&npm` as
one token, so unspaced `&&` and `;` re-adds were invisible; `shlex` in punctuation_chars
mode splits them. Added: `sh -c` payload expansion, `npm --prefix`/`npx -p` flag skipping,
`xargs`, heredoc bodies as DATA (a `cat > f <<'EOF' … npm test … EOF` block counted as a
real run), `ADD`/JSON-form/no-trailing-slash `COPY` in `carries_spa_source`, and
redirections no longer read as spec filters. `--root` and `--config` moved to the
narrowing set: both change which specs vitest collects.

A FACTUAL ERROR, in five places including the mutation `expect`: "the build context is
`web/` + `design-system/`, so there is no `.git`". The context is the repository root
(`context: .`) and `.dockerignore` does not exclude `.git`. The true statement is about
the STAGE, which copies only those two directories. The conclusion survives — bookworm
slim has no git binary either — but a reader who checked would have found `.git` in the
context and concluded the note was stale.

ONE FINDING WAS MINE, from the mutant battery rather than from either review, and it is
the reason the battery exists: `failure_suppressions` tokenised the whole multi-line
`run:` body at once. A newline is not a shell separator, so a realistic two-line step —
the `ci-step-ran.sh` marker line, then the suite — merged into ONE segment whose head was
the marker script, and three suppression mutants passed while my single-line unit test
was green. It now works per logical line, and the regression test uses the two-line shape.

17 mutants, 0 missed, each caught by the intended assertion; baseline green. The
`docs/guard-inventory.md` residual list is rewritten as MEASURED reach — the previous one
was wrong rather than merely short, which cold review rightly called worse than silence.

timothyandClaude Opus 5 febaad77d7 fix(887): the image build builds the SPA and does not test it
`docker/Dockerfile`'s web-build stage is gitless twice over — the build context is
`web/` + `design-system/` so there is no `.git`, and `node:22-bookworm-slim` ships no
git binary. Members of the SPA suite need one or the other, so running the suite there
required naming the ones that cannot run. That list was a population nothing derived:
#883 added a third member without updating the hand-written pair of `--exclude`s, and
because `Build & push image (amd64)` is `if: github.event_name != 'pull_request'` the
resulting red was unreachable on a PR. It landed on `main` and on the `v*` tag path
instead — every image build failed, `:latest` stopped being republished, and a release
cut would have failed at the image build.

Adding a third `--exclude` re-arms the trap, so the list is removed rather than
extended: the stage now lints, typechecks and BUILDS the SPA, and the suite runs once,
unfiltered, in `docker-build.yml`'s `test` job on a real checkout. `build` carries
`needs: [test, migrations, scan]`, so no image is published past a red suite.

`scripts/tests/test_image_build_delegates_the_spa_suite.py` holds both halves — the
negative one alone would be satisfied by deleting the `needs:` edge. Three populations,
all derived: tracked Dockerfiles and workflows from the git index, and which npm scripts
ARE the suite from `web/package.json` (so `test` is in and the Playwright `test:ui-e2e`
is out, with no exemption list). Publishing jobs come from the `docker/build-push-action`
step and the Dockerfile each builds from that step's own `file:` input, which is why
`ci-image.yml` is out of scope by derivation rather than by an entry that would outlive
its reason.

Four mutants witnessed red, each by the intended test: a filtered suite run put back
into the Dockerfile, the `needs:` edge deleted, and the gating run narrowed in both the
block and the single-line `run:` step forms.

#859 was filed as a wrong STATED CAUSE. It was masking a live false-open in the merge gate.

Gitea reports a GLOB branch-protection rule with an EMPTY `branch_name` — the canonical
name lives only in `rule_name`. Measured 2026-08-30 on a scratch repo against 1.27.1.
jq's `//` fires on null and false but NOT on `""`, so `(.branch_name // .rule_name // "")`
resolved every glob rule to the empty string — a name with no metacharacters — and the
glob test, the entire basis of the classifier's undecidable-first ordering, never saw it.

Measured on the predecessor: glob `m*` (not requiring review-verdict/h10) beside plain
`main` (requiring it) resolved to `exact` on `main` and AUTO-GRANTED a scheduled merge,
while Gitea — ordering by Priority then plain-name-ness — may be applying `m*`. That is
#622's hole, reached through the ordering written to close it. Mirror case: a glob alone
resolved to `none` and DENIED about a rule that provably governs the base.

A name is now a non-empty string. Each field resolves to a NAME, a SKIP (absent/null/
empty — fall through), or POISON (present, wrong type — poisons whichever field carries
it). A rule with no usable name is a distinct `unreadable` verdict with its own operator
cause, instead of feeding `none`, whose whole authority is "the full rule list was read
and none matches". The short-circuit is STRUCTURAL: jq binds `as` eagerly, so the flat
form still evaluated `offs`/`nonascii` on the bad name and died before reaching the arm
meant to prevent that.

Also #859: `branch_protections` is fetched ONCE per run, not twice. The round trip is the
smaller half — it is mutable config, so two reads can disagree and the two arms then
decide about different repo states with neither able to notice.

#858: `verdict_script` resolves from `$repo_root`, not `$CLAUDE_PROJECT_DIR`. And the
finding that mattered more — `ETV_HOOK_FIRE_LIB` is `. `-SOURCED, so it is CODE running
before stdin is read and before `decide` exists. A first draft exempted it as "telemetry,
not a predicate"; cold review refuted that by execution: a decoy hook-fire-log.sh in an
env-var-named tree printing an allow and exiting 0 GRANTS THE MERGE, bypassing every
check. Classify a path by how it is CONSUMED, never by what it is called. This hook's copy
is self-located; the other twelve are #891 (high/security), which records the reachable
case — husky launches the prepush hooks by RELATIVE path, so the two roots diverge there.

check-required-contexts.sh gains an array-type gate (a JSON object previously printed
`nomatch`, a positive claim about server config from a body it cannot consume).

Verification: 1377 passed / 2 skipped; 11 declared mutants, 11 detected, disjoint
reddened sets; classifier executed across jq 1.8.2 and 1.6 with identical results; both
env-var tests ship a negative control, because the passing outcome is also what an inert
decoy produces.

Four cold review rounds plus a bounded prose check. Every round found defects the
previous round's fixes introduced — a type conflation that re-opened the auto-grant, a
comment asserting the opposite of the line its own commit changed, and a corrected
sentence whose identical twin survived in the same diff.

Docs: new record `process.hook-resolves-inputs-from-repo-root`; both inline sites cite it
rather than arguing it twice. docs/remote-state-inventory.md's row for the second read
updated. Follow-ups filed: #891 (the other 12 hooks), #895 ("all N tests green" claims).

`count_pr_mutations` treated an empty page past page 1 as proof it had reached the end of the PR
timeline. Gitea does not mean that: `ListIssueCommentsAndTimeline` applies the LIMIT/OFFSET in
`FindComments` at the DATABASE level and filters AFTERWARDS, dropping `CommentTypeCode` rows and
inaccessible cross-references into a nil slice that serializes as bare `null`. A page of 50 inline
review comments is byte-identical to a page past the end while later pages still hold events, and
rows are ASCENDING, so the events a fence looks for are the furthest from page 1. Fifty comments,
which a PR author can create on their own PR, truncated both walks at the same place: both counts
agreed, the sha comparison agreed, and an ABA force-push yielded an exemption `success` over a diff
no single head justified.

The walk no longer infers the end from an empty page BEFORE its cap. Such a page is skipped; the
loop reads every page to its 20-page cap and trusts the counts only when the LAST page came back
empty. An empty FIRST page and any unreadable shape still end the walk untrusted.

NARROWED, NOT CLOSED, and the docs say so in one unit: the page-20 terminator is still trusted for
the same unprovable reason, so the defeat now costs a timeline of over 1000 rows rather than ~100,
with the same 50-row filtered block pinned to offsets 950..999.

Measured at Gitea 1.27.1, ruling out the cheaper fixes: `X-Total-Count` on this endpoint is the
post-filter length of the PAGE, not a total (`?limit=1` returns 1 on a 14-row timeline), while
`/activities/feeds` returns a true total; `limit` clamps to 50; the only query params are `since`,
`before`, `page`, `limit`, so the paged and serialized sets cannot be made to agree.

Also: each page bounded `--connect-timeout 5 --max-time 15` and retried once, mirroring
`page_statuses`, because the walk went from ~2 requests to a fixed 20 and the third call site runs
after the exemption `success` is posted. Costs stated rather than hidden — worst case 40 requests
and 20 sleeps, wall-clock pessimum 620s per walk, and the suite roughly doubled (202s -> 474s).

Seven tests, each mutation-witnessed red; three reproduce the defeat against the shipped predecessor.
Two independent cold reviews plus a re-review of the fix: no Blocker or High in the code. Their real
finding was prose claiming the hole was closed, and cost arithmetic wrong twice. One reviewer claim
was refuted by execution.

review-verdict/h10 Review-verdict: MERGEABLE @ d4b36ac (base: main)
The round-9 cross-family review found no Blockers and no Highs, and independently confirmed
the clause deletion it was asked to check. What it did find is that round 9 removed FIFTEEN
test definitions and added four — a net loss of eleven — where the commit message claimed
two. Verified against the parent: 227 definitions before, 216 after.

The cause is mechanical and worth naming, because it produces a green suite: the round-9
edits replaced whole source RANGES (`s[:start] + new + s[end:]`) whose end anchor was the
next test rather than the end of the one being rewritten, so everything in between went with
it. The suite then passed because the tests were GONE, not because the code was right — the
exact shape this issue exists to prevent, reproduced in its own test file.

Among the casualties were round 4's proofs for two earlier BLOCKERS:

- `test_a_generic_PENDING_with_no_mark_also_becomes_the_sentinel` and its mutation, which
  pin the no-mark downgrade covering every re-derivable write rather than only `success`;
- `test_a_MALFORMED_creator_FIELD_...` and its mutation, which pin a wrong-typed field
  taking the fault route rather than reading as absent and licensing a re-derive.

Also lost: both `$own`-exclusion proofs, the no-op-repair skip proof, the id-asymmetry pair
(the reviewer's named example), and two write-failure propagation proofs.

All 13 unintended deletions are restored verbatim from the parent commit and ALL PASS against
round 9's code, so nothing had regressed — the harm was the missing evidence, not the
behaviour. The two deletions that WERE intended stay deleted: a test superseded by
`..._still_refuses`, and the positive control round 9 inverted.

Prose: the comment above the unreadable-element guard still argued a malformed neighbour is
safe noise once the target row was found, eleven lines above code that now refuses
unconditionally — two adjacent blocks giving opposite accounts of one rule, and the stale one
licenses reinstating the Blocker.

The round-8 cross-family review found two more Blockers. Both are cases where a principle
this branch had already established was applied in one place and not the adjacent one.

## Sentinel text is not sentinel state

`ex_repair` and `ex_unverified` were set from the DESCRIPTION alone. A `success` carrying
`$REPAIR_DESC` verbatim — from a machine or an off-list account — therefore read as a
sentinel: the mid-run guard exited on it, and the mark's already-there test matched it and
returned without POSTing. A green stood on an unreviewed head, on a first-push event with no
successor guaranteed.

This is the same reasoning that removed the "this job's own output" exclusion one round
earlier: a description is not provenance. It is not state either. Both sentinels this job
writes are `pending` by construction, so requiring it costs nothing.

## An unreadable neighbour cannot be shown to be unrelated

Round 8 refused only when NO readable target row was found, reasoning that a malformed row
beside a good one is noise. An element whose `.context` cannot be read cannot be shown to be
a DIFFERENT context — so it may be a mangled rendering of this head's own rejection, and the
one-row-per-context invariant that would rule that out is exactly what a schema-corrupt
response has already broken. The branch's own POSITIVE CONTROL encoded the failing case: a
scalar beside an off-list `success`, which this branch re-derived and greened where
`origin/main` errored on the scalar and posted nothing. That test is inverted, not adjusted.

The cost is a stall on any head carrying a malformed element — the correct direction for a
required check, since it withholds a green rather than granting one.

## Two clauses deleted rather than proved

Chasing a proof for the mark's repair promotion showed its three clauses were MUTUALLY
REDUNDANT: each alone produces the outcome, so no single-clause mutation could show harm.
Tracing why revealed that two are unreachable as a sole cause — a repair sentinel at the
first read sets `ex_repair`, which forces `desc="$REPAIR_DESC"`, and one arriving mid-run is
caught by the sentinel guard unless this run is itself writing that string. So they are
redundant rather than unprovable, and they are gone. One clause, one mechanism, one proof.

timothyandClaude Opus 5 691a14d039 fix(849): round 8 — a green main does not post, and two round-7 fixes that overshot
The first cross-family review in five rounds (Codex/GPT-5.6, once its quota reset). It found
a Blocker four same-family rounds had missed, and REVERSED two of round 7's fixes — which is
the more useful result, because both were made in response to a review and both overshot in
the direction the finding pointed.

## The Blocker: dropping unreadable elements became "no verdict exists"

Round 3 added `select(type == "object")` so a malformed NEIGHBOUR could not kill the step.
When it drops EVERY element, `first // {}` yields `{}`, all `ex_*` read empty, and the job
concludes no verdict exists — so a docs-only PR walks straight to the exemption. Measured:
`{"total_count":1,"statuses":[7]}` posts `Exempt: docs-only change` here and posted NOTHING
on `origin/main`, which raised jq error 5 and aborted under `set -e` before any write. An
input on which this branch greens a head that `main` fails closed on, and if that scalar is a
mangled rendering of the head's human `failure`, the rejection is what gets greened.

The asymmetry is now the rule: a malformed row BESIDE one we did read is noise; a malformed
row where we found NOTHING is the only evidence there was. The absence conclusion has to be
earned over a list with no unreadable elements in it.

## Two round-7 fixes that overshot

- **The arms judged both snapshots.** Round 6's review said they judged `$pre_*` while the
  POST replaces `$ex_*`; I made both veto, which is the mirror defect — an opening row since
  REPLACED by a machine `success` still vetoed, so the arm left that success gating the head.
  They judge the current row alone now. The opening snapshot keeps exactly one job: it can
  make the write STRONGER, never suppress it.
- **The "this job's own output" exclusion keyed on the DESCRIPTION.** A description is not
  provenance. Any workflow with `code: write` can POST a `creator: null` row and any
  repository writer can POST one with a creator, either wearing this job's text — so masking
  a human `failure` with a lookalike `pending` bought an abstention, and the successor
  re-derived it as ordinary machine output with the rejection below its own mark. Removed;
  the attempt is recorded because it is the tempting one, and there is no issuer field that
  could make it safe.

## A guard that could not be reached, folded into the one that can

The repair veto turned out unreachable: an `$ex_desc` of `$REPAIR_DESC` with a different
`$desc` is caught by the mid-run sentinel guard long before an arm runs, and when `$desc` IS
`$REPAIR_DESC` the promotion writes the same string. Rather than keep a guard no fixture can
reach — or delete it on the strength of a check three hundred lines away — the invariant is
enforced where it is local and provable: the mark carries the strongest description any
snapshot shows, then declines to write what is already there.

`ci.exemption-provenance` still called the post-final-count window a PERMANENT forged green
in its `rule:` frontmatter and body; the post-POST re-count made it transient two rounds ago.

timothyandClaude Opus 5 72cca9a280 fix(849): round 7 — the arms judged the wrong snapshot, and two comments that invited a bug
A fourth cold review of the tip. No Blockers, no High: it enumerated every POST site and
every exit and could not construct an input where this branch writes a `success` that
`origin/main` would not.

## The arms judged the wrong snapshot

`mark_declined_row_if_any`'s three refusals all read `$pre_*` — the FIRST read — while the
POST replaces whatever row is CURRENT. So a reviewer's verdict arriving between the two
reads slipped past every refusal written to protect it: the base mismatch clears
`ex_attributable` so the mid-run abstain declines, `pre_creator` is empty so the allow-list
loop declines, and the arm marks a row nobody evaluated. Executed trace, control and case.
Both snapshots are consulted now, and either one vetoes.

Recovery was not free, which is why it mattered: the next run's reconciliation counts that
`Review-verdict:` row as buried and upgrades to the human-only sentinel — exactly the cost
the refusal exists to avoid.

The arm also marked this job's OWN ordinary machine `pending`. Every PR past its first run
carries one, so "kept off the commonest path in this job" was true only of a head with no
status at all. Scoped on the DESCRIPTION rather than on `creator: null`, which would also
exclude a machine `success` from another workflow — the row this marking exists for.

## Two comments that invited a bug

- One still described the round-4 REGRESSION as the intended behaviour ("a malformed row
  reads as no creator, hence re-derived"), two lines below the block recording that it was
  fixed. Adjacent comments giving contradictory accounts of one line, and the stale one
  licenses reinstating it.
- The fault token's justification said "no Gitea status field contains a NUL". The token is
  SOH (0x01). That is not pedantry: `$'\000…'` is the EMPTY STRING in bash, so an editor
  correcting the code to match the comment would make every legitimately-absent field
  compare equal to the token and send every clean head down the fail-closed route — the gate
  would stall every PR.

## Docs

The record quoted a predicate that no longer exists (`[ "$ex_desc" != "$pre_desc" ]`, now
`$row_replaced`); `docs/ci-cd.md` stated the reconciliation witness unconditionally when the
code degrades to a description match where the server omits `id`; one of the six unproven
clauses carried a wrong `because` (the conclusion holds via `(.id | numbers) // -1` over a
validated array, not via the schema-fault route, which governs a different endpoint's row);
and the record's own counts read as a contradiction cold — 20 surviving MUTANTS collapse
onto 6 distinct CLAUSES, several clauses admitting more than one disarming edit. The
run-by-run provenance moved to the issue, where `docs.no-session-narrative` says it belongs.

Two existing mutation proofs lost their binding to the reworded clauses and failed loudly
rather than measuring the unmutated body, which is what that count assertion is for. Rebound.

timothyandClaude Opus 5 bbaf1d76f8 fix(849): round 5+6 — the survivors a mutation SWEEP found, and the six that cannot be reached
Codex was unavailable for this round (usage quota), so the cross-family reviewer was
replaced by a same-family agent doing one mechanical job: enumerate every security-bearing
clause the diff adds, disarm each, and run the WHOLE suite per mutant. 60 mutants, 40 red,
20 survivors — a yield no per-finding review in this series came close to, because a review
looks at what the diff says it does and a sweep looks at what the tests actually pin.

## Proved (nine)

- the description type test in the RECONCILIATION `buried` filter — exact twin of the
  post-write one, which had a proof; without it a numeric description hard-errors
  `startswith`, the count comes back unusable, and the genuine verdict on the next row is
  lost with it;
- the `.status` / `.description` / `.id` type tests, parametrised over all four consumed
  fields so a fifth cannot be added without a case (`.creator`'s was the only one proved);
- both retry loops — the combined read and `repair_status_to`'s second POST. Against a stub
  that fails EVERY attempt a retrying reader and a one-shot reader are indistinguishable,
  which is how a retry ships unexercised; the fixtures now fail only the first attempt;
- the mid-run guard's self-exemption, which is what stops a sentinel-writing run abstaining
  on the row it was about to replace with an equivalent one;
- both repair-write failure paths (the repair and the post-POST replacement), reachable only
  with a stub that lets the FIRST post through and fails the rest — with every post failing
  the job dies on its own classification write and never reaches them;
- the two `state=pending` updates after a repair. The first is load-bearing beyond tidiness:
  without it a repaired head re-enters the post-POST check and, on a retarget it then
  observes, replaces `$REPAIR_DESC` with the weaker reconcilable sentinel — the same ordering
  inversion the floor beside it exists to prevent, reached by another route.

## Declared unreachable (six), enumerated rather than counted

The path-predicate failure branch; the empty-`row` refusal; page 2's non-numeric length; the
`$witness` normalisation; and the two unusable-count arms. Each is defence in depth behind a
filter that makes its input well-formed for every case a fixture can pose — the same standing
exception the post-write unusable-count arm already carried.

That set has gone two -> five -> six across three rounds as the sweep widened. Naming them is
the point: an inventory that undercounts reads as a checked claim and talks the next reader
out of verifying, which is the same defect as inventing coverage — and this branch has
already had to correct that twice.

timothyandClaude Opus 5 28e82fcb59 fix(849): round 4 — a regression round 3 introduced, and the clauses it left unproven
A third cold review, which ran the mutants itself, found one measured direction regression
against `origin/main`, one ordering inversion, and four clauses this branch claims as
fixes that survived mutation of their own text.

## The regression

Round 3 type-tested the four consumed fields of the existing `h10` row and resolved a
failure to `""`. For `.creator` that means "no creator" — unattributable — which is a
LICENCE TO RE-DERIVE. Measured, same fixture, both bodies: a head carrying
`h10=failure` with `"creator": 7` posts `Exempt: docs-only change` here and posted NOTHING
on `main`, which died on `.creator.login` before any write. Fail-closed became fail-open.

The rationale that produced it came from #763, whose site is the POST-WRITE filter: there,
dying leaves a green already published, so dropping the row is the safe direction. Here the
alternative is dying BEFORE any write. The deferral rationale did not transfer — which is
the shape this repo has a record for.

A wrong TYPE is now distinguished from a legitimately ABSENT value: `null` is the machine
creator, an unset description and every field of the `{}` no-verdict row; anything else is
unknown state and takes the route an unreadable ELEMENT already took.

## The ordering inversion

`mark_declined_row_if_any` was scoped to "the head carries any row", so it fired on a head
carrying `$REPAIR_DESC` and replaced the human-only marker with the machine-clearable one —
inverting the ordering the SAME commit added a floor to protect at the repair site. One
mechanism, three writers, and only two had the rule.

It also buried a verdict an ALLOW-LISTED reviewer wrote for another base. "Declined" is
decided against this event's `$BASE_REF`, so such a row is still the right answer for the
base it names and the successor run for that base short-circuits on it; burying it costs a
manual re-post on an ordinary retarget-onto-the-reviewed-base flow. Membership is tested on
the raw creator, not on `ex_human`, which the base check has already cleared — the question
is who wrote the row, not whether it governs this diff.

## The unproven clauses

Four claims survived mutation, including the headline one. The witness fixture had been
designed AROUND its own discriminator — its comment said a seed with an unrelated id "would
make this run carry the sentinel forward … and the guard under test would never be reached",
which is a description of the test not reaching it. Eleven proofs added, covering the
witness-by-id, the head arm's own call site (two callers of one helper, one fixture), the
mark helper's result propagation, and the round-4 behaviour above.

`raced_why`'s human value is a named constant now: it is the one such value that is also a
PREDICATE, compared twice, and a drift in either copy silently downgrades the human
`::error::` — the only message that tells a reviewer their verdict was buried.

## Docs

The renamed sentinel literal in two places; three documents still asserting the fence
"writes NOTHING"; the record's `mechanics:` still describing round 2's witness; the
replacement-site list, which had grown by four; a residual pointing "below" at something
above it; and `CLAUDE.md`'s "closed", which is stronger than the record it points at — that
record lists six residuals including both endpoints failing at once. The proof inventory is
stated as an invariant (every clause with a predecessor is mutated back to it) rather than a
count that rots.

timothyandClaude Opus 5 168fe21088 fix(849): round 3 — replace every unknown state, and prove the clauses that claim to
Two more cold reviews — cross-family (Codex/GPT-5.6) and a cold Claude reviewer that ran
the mutants itself — converged on two separate things: a remaining class of paths that
still left an unknown state standing, and, more importantly, that several clauses this
branch claimed as fixes SURVIVED mutation of the exact text they name.

## Behaviour

1. The reconciliation witness matches the CURRENT row's `id`, not merely a row with the
   sentinel's description. Description alone is satisfied by an OLDER identical sentinel —
   which is what a fixed point produces — so a read carrying only the earlier row cleared
   the sentinel while the verdict buried under the current one ended up below the fresh
   mark. Falls back to the description where the server omits `id`.
2. The two OBSERVED-mutation arms mark a head that carries a row this run declined, instead
   of only abstaining. They are still right not to post their CLASSIFICATION — computed
   against a base or head the PR may no longer have — but a declined row must not stay
   authoritative for the whole window until a successor finishes, and for a PR's FIRST push
   no successor is queued at all. Scoped to `pre_state` being non-empty, so the common path
   stays quiet.
3. `replace_unknown_state` RETURNS a status. Its first version ended the failure arm with a
   successful `echo`, so it reported 0 after both POSTs failed and the fence caller's
   `exit 0` reported an abstention that had not happened.
4. An `id` difference counts only when BOTH reads supplied one. A response that omits `id`
   beside one that includes it otherwise reads as a replacement, and this guard's reaction
   is to abstain — over a row the classification had already declined.
5. Every element and every consumed field of the combined response is type-checked before
   extraction, and a schema failure routes to the replacement. `.statuses` being an array
   was checked; its ELEMENTS were not, so one scalar made `select(.context == $c)`
   hard-error and `set -e` took the step down before any path could mark the head.
6. The path-predicate failure replaces rather than merely exiting, for the same reason.
7. `$UNVERIFIED_DESC` says "Status write", not "Exemption write". It is now written on paths
   that grant no exemption at all, and it is the operator-facing text of a required check.
8. The no-op-repair skip keeps the human `::error::`. Skipping the WRITE is right — the head
   already carries the strongest marker — but that message is the only place a reviewer is
   told their verdict was buried. `raced_why` is a sentence now, not the token `human`.

## Proof

The cold reviewer measured three of the six round-2 claims surviving mutation of their own
clause, one against the verbatim predecessor from the previous commit. Nine proofs added:
the no-mark downgrade's SCOPE (not just the description it writes), the page-2 refusals, the
untrusted-fence write, the row-`id` comparison, the repair floor, the no-op skip, both `$own`
exclusions, the write-result return, and the both-ids-present rule.

Two of those needed the test double to grow: the combined-status stub emitted no `id` at
all, so the `ex_id` clause had never once run with a non-empty value; and POSTs always
succeeded, so both write helpers' failure arms were unreachable.

The `$own` exclusions and the no-op skip are OUTCOME-redundant — mutating either alone leaves
the post sequence unchanged, which is how duplicate guards hide each other. Their proofs
assert the LOG, because what the exclusions alone decide is whether the job reports a race
against its own row. One clause is left deliberately unproven and named as such in the record
and the guard inventory rather than counted: the path-predicate failure branch has no fixture
that can reach it.

## Also

Round 2 left two comment paragraphs duplicated verbatim and a block header narrower than its
block; both fixed. Stale prose corrected in the workflow ("dies WITHOUT posting", "post-write
verification never runs for it", "this block only runs after a `success`"), `docs/ci-cd.md`
("the fence never re-counts", "the history is read twice" — it is three now),
`ci.exemption-provenance` and `docs/guard-inventory.md`.

timothyandClaude Opus 5 957a328f33 fix(849): round 2 — the uncertainty paths that still resolved toward success
Two independent cold reviews (Codex/GPT-5.6 cross-family, and a cold Claude reviewer in
its own worktree) converged on the same class: paths where "this job cannot establish
what is on the head" still resolved by leaving the head alone, which protects a real
verdict and leaves a forged one.

Behaviour:

1. The four page-2 completeness refusals now replace the unknown state too. They were
   excluded on the reasoning that the probe fires when NO row for this context was on page
   1, so there is no green of any provenance to leave standing — self-contradictory, since
   the only reason page 2 is read is that the row may be beyond page 1, which the probe's
   own message says. Accepted cost, stated in the record: a head with more CONTEXTS than
   the 50-row cap stalls every run; measured 2026-08-29, this repo puts 8 on a `main` head,
   and that case already stalled with an ABSENT check.
2. The no-mark downgrade covers every re-derivable write, not only `success`. Restricting
   it analysed the wrong PR: the damaging case is one that IS exemptible and got the
   generic `pending` only from a transient enumeration failure. That description carries no
   marker, nothing verifies it without a mark, and the next run re-derives it into the
   exemption with the human row below its own mark — route 2's damage through route 1's
   condition. `$REPAIR_DESC` stays exempt, being stronger and not re-derivable.
3. The fence branch that cannot trust its retarget count while holding a derived `success`
   writes the sentinel instead of abstaining. It is reached only after the classification
   DECLINED to inherit the row the head carries, so posting nothing left that row current;
   the message said the context "stays absent", true only of a head that had none.
4. Reconciliation needs a WITNESS: it may clear only over a complete history containing the
   sentinel's own row. `ex_unverified` means the combined endpoint just returned that row
   and `/statuses/{sha}` keeps one per POST, so a complete-but-empty history contradicts a
   write that demonstrably happened — and `page_statuses` accepts an empty page 1 as
   complete, which is what made it reachable. Both reviewers reproduced the clear-then-exempt
   outcome. The shipped positive test used exactly that impossible fixture, so it was
   pinning the defect; it now seeds the sentinel row, and an impossible-empty negative plus
   a witness mutation proof were added.
5. The mid-run "did this row change" comparison now includes the row ID. The two sentinels
   are byte-identical by design, so a mid-run replacement of one by another was invisible to
   a state/creator/description triple. Measured 2026-08-29 (Gitea 1.27.1, head 736649b3):
   the COMBINED endpoint carries `id` on every row, ids 14..30 ascending — the job had only
   ever read ids from `/statuses/{sha}`. Where a server omits it both sides are empty and
   the comparison degrades to the pre-existing text test.
6. The repair has a FLOOR — it may never write a description weaker than the one this run
   decided — and is skipped when it would rewrite what is already there. Widening the gate
   to every write meant a transient post-write read could rewrite a correct `$REPAIR_DESC`
   carry-forward with the machine-clearable sentinel, reversing the ordering rule the
   classification chain states.

Writing the sentinel and failing the job are separate decisions, which is why
`replace_unknown_state` and `replace_unknown_and_die` are two functions: the read refusals
were already non-zero exits on `main` and stay red; the fence branch exited 0 there and
still does, because an unreadable timeline is an ordinary hiccup and reddening every one is
noise this file elsewhere refuses to add.

Prose corrected where it now overclaimed: "the green never stands" after the post-POST
re-check is wrong — it is live between the POST and the repair, so the check makes a
permanent green TRANSIENT; "a later run reconciles this automatically" is wrong in the one
case where the replacement costs anything, since finding a masked verdict UPGRADES to the
human-only sentinel; and the mutation-proof framing claimed every mutant restores the exact
predecessor, when two do, one restores the shape #742 withdrew, and the rest disarm clauses
that have no predecessor. The quiet-timeline positive control now counts timeline walks,
because a single POST is also what a skipped re-check produces.

timothyandClaude Opus 5 e30702111f fix(849): verify every write, and mark a head nothing could verify
The gate's post-write verification had five routes that all ended the same way — an
exemption `success`, or a generic `pending` a later run turns into one, standing over a
human `failure`.

Two of these were attempted inside #742 and withdrawn, and the withdrawal is what shaped
this change. That attempt withheld the exemption by writing a GENERIC `pending`, which is
exactly what a later run re-derives into `success` — it moved which run posted the forged
green rather than stopping it — and it had no retry path, because this workflow triggers
only on `pull_request_target` types, so a transient failure on a PR's last event stalled an
exempt PR until a human nudged it. The fix therefore needs two properties at once: sticky,
so a later run cannot re-derive it, and reconcilable, so a blip does not cost a head its
exemption permanently. Neither the repair sentinel nor a generic `pending` has both, which
is why there is now a second sentinel rather than a reuse of the first.

What changed:

1. No high-water mark => the exemption is WITHHELD before the POST and the head is marked
   with the new `UNVERIFIED_DESC` sentinel. Withholding before the write rather than
   posting and repairing matters because the defect is known in advance: publishing a green
   to take it back opens a window branch protection, and an already-scheduled auto-merge,
   can see.
2. Post-write verification runs after EVERY write, not only `success`. A generic `pending`
   masks a rejection landing in its own write window just as well, and carries no marker,
   so the next run re-derives it with the human's row now below THAT run's mark.
3. `.description` is type-tested before `startswith`. `(.description // "")` does not
   replace a NUMBER, so `startswith` hard-errors on one, killing the whole count — the
   genuine verdict beside the malformed row is lost with it.
4. The retarget count is re-taken AFTER the POST on the exemption path, closing the
   PERMANENT forged green `ci.verdict-write-retarget-fence` listed as its residual 1. The
   retarget axis only: a push after the POST moves the head, so the status no longer gates
   that PR, while a retarget changes the effective diff with the sha unchanged.
5. An unreadable combined-status read retries once and then REPLACES the unknown state
   instead of declining to write. Declining protects a real verdict and leaves a FORGED one
   — an off-list `success` is the row #742 exists to revoke, revocation happens by
   re-deriving it, and the job then went red on a status branch protection does not read.

One defect this introduced and fixed on the way: widening the post-write gate to every
write made the job match its OWN row, because the machine-sentinel arm selects on a null
creator. A run taking the carry-forward path POSTed `$REPAIR_DESC`, then found "a sentinel
above the mark", then repaired to the identical description. `--arg own "$desc"` excludes
it, by description rather than by id — the id of the row just written is not knowable
there.

Reconciliation is what bounds the stall: a later run pages `/statuses/{sha}` in full and
either finds a `Review-verdict:` row underneath the sentinel — an established fact, so it
upgrades to the repair sentinel, clearable only by a human — or finds none and clears it.
It is sound because the two endpoints disagree: a masked verdict is invisible on the
combined endpoint (latest row per context, which is the sentinel) and still present in the
per-POST history.

Tests: each fix is paired with a `test_MUTATION_…` proof that restores the exact
predecessor text through a new `_run_classify(mutate=…)` knob, whose count assertion is the
binding — a clause that has since moved substitutes zero times and fails loudly rather than
measuring the unmutated body. Two CHAINED tests feed run N's real output into run N+1,
because both sentinels are fixed points and a single hop cannot assert a fixed point: the
raced-`pending` repair must survive the run that would otherwise grant the exemption, and
the unverified sentinel must not decay while it cannot be reconciled.

Docs: new record `ci.verdict-unverified-write-sentinel`; the now-false guarantee prose in
`ci.verdict-write-retarget-fence` (its `rule:` frontmatter, the "resolves it" opener, "the
fence above closes", the truncating-block claim and residual 1), `ci.exemption-provenance`,
`docs/ci-cd.md`, `docs/remote-state-inventory.md` and `CLAUDE.md` corrected by concept
rather than by phrase, per the scope boundary recorded on the issue.

`review-verdict.yml` inherits an existing `review-verdict/h10=success` only from a status whose
`.creator.login` is on its `H10_REVIEWERS` allow-list (#742). `post-review-verdict.sh` wrote those
verdicts with whatever account owned the credential in the environment and never asked whose it was.
Two coupled values, nothing asserting the coupling, and the failure was the silent kind: the status
is written, the tool reports success, and the next `pull_request_target` event re-derives it and
posts over it. The PR stalls with no visible cause.

The writer now READS ITS OWN STATUS BACK, identifies that write by state and description, and
refuses — before the verdict comment, so the surviving half-state is the documented `ask` one —
unless the recorded creator is allow-listed. Measured after the write rather than probed before it:
that tests what Gitea recorded as the author, which is the value the gate reads, and needs no scope
beyond the repo access the POST already required.

Membership is required for a `success` ONLY, mirroring the gate's own asymmetry: a `failure` is
inherited from any attributable account, so requiring it there would refuse a verdict the gate
honours and leave an off-list reviewer no supported way to record a rejection.

The allow-list is DERIVED from the gate's own literal by the new `scripts/lib/h10-reviewers.sh` —
one declaration, not two plus a parity test. It is a parse rather than a shared declaration both
sides source because the gate runs against a checkout of the PR's BASE sha: a PR whose base predates
such a file would not have it, and a missing `source` under `set -euo pipefail` kills the job, which
posts no `review-verdict/h10` at all and blocks every merge including its own repair (#743).

`scripts/post-review-verdict.sh` moves BEHAVIOUR-ONLY -> MUTATION in the guard inventory, which the
manifest's own note called "the most valuable upgrade on this list". The declared clause lives in the
GATE: rewriting `H10_REVIEWERS` while the posting account stays fixed reddens the accept path only if
the writer reads the list live AND the comparison gates the outcome.

Two defects were caught by probing the live instance rather than re-reading the code. Reading `.state`
instead of `.status` per row would have refused EVERY verdict — a repo-wide deadlock, shipped green,
because the test shim replayed the POST payload as the read-back body and so agreed with the parser
by construction. Then a `(.status // .state)` fallback added as defensiveness recreated #845 exactly:
the writer would accept a shape the gate cannot read and report success.

Nine independent cold review rounds, all worktree-isolated, one cross-family (GPT-5.6 via Codex).
Round 8 caught the most important one: a `set -u` "correction" made mid-branch had inverted a TRUE
statement in live merge-gate code, because the probe used a plain `$UNSET` while the validator uses
`${#arr[@]}` — different shapes, different behaviour. Withdrawn wholesale; both libraries are
byte-identical to `main` again.

Verification: full `scripts/tests` suite green (1278 passed, 2 skipped); the declared mutation
executes every run and reddens its named proof with the manifest's `expect` string; every clause
disarmed individually and confirmed to redden its own named test; live probes against Gitea 1.27.1
for the row shape, the description round-trip, the paging order and the required-check list.

Docs: `ci.exemption-provenance` records the coupling as asserted rather than as a tracked residual,
plus `docs/ci-cd.md`, `CLAUDE.md`, `docs/guard-inventory.md`, `docs/remote-state-inventory.md`,
`ci.script-tests-job` and the `script-tests` population comment in `pr-checks.yml`.

Deferred: the refused-verdict residual (a non-inheritable status left standing with no comment) is
the `ask` half-state `release.verdict-writes-status-before-comment` designates as safe; a second
corrective write is the sticky-sentinel mechanism #849 is separately designing.

Both fetch sites now go through `fetch_ref`, which passes `--depth` only when the checkout is already shallow. `Compute version and tags` fails the job instead of defaulting, so no `:latest` is published rather than a mislabelled one; releases are unaffected because the tag path never calls `describe`.

`Complete<T>` (#807) makes SPA full-replace bodies fail typecheck when a builder omits a schema member. Nothing checked it was APPLIED: `completeRequest.guard.test.ts` proves the type's semantics and would stay green with every annotation deleted, and `test_optional_request_members.py`'s COVERED disposition — "the builder is annotated `Complete<T>`" — was a claim about another language's source that nothing verified.

Adds `completeAnnotationScan.ts` (compiler-API scanners) + `completeAnnotations.guard.test.ts`, with a synthetic-source fixture suite. Two derived populations: the `Complete<…>` annotations (SPA AST ∩ git index) and the droppable schemas (parsed from the generated `v1.d.ts`, a pass-through of the OpenAPI `required` array). It asserts a production annotation per schema dispositioned as needing one, NO annotation on the server-computed and load-bearing-omission schemas, that every `Complete<X>` resolves to a generated schema rather than a hand-written mirror, and set equality between droppable schemas and the reviewed dispositions. `test_complete_annotation_dispositions.py` cross-checks that table against the authoritative Python one and ships a declared, harness-executed mutation.

Found one live defect: `playouts.ts` declared two request types as hand-written mirrors SHADOWING generated schemas of the same name, so their `Complete<>` was checking a local copy rather than the contract — the #754 mechanism wearing the annotation meant to prevent it.

Eight review rounds, seven BLOCKED, two independent cold reviewers. A wrapper-signature scanner was built and REMOVED: every blocker traced to that one mechanism (obligation on the wrong population; reachability mistaken for protection, since `Complete<T>` is shallow; body discovery keyed on a parameter name, then parameter-vs-local; and finally `export function` → `export const` blinding the scanner and its cross-check together). Five defects from one mechanism, so the mechanism went rather than a sixth patch.

Residuals stated in §4b, the guard-inventory row and the record: per-SCHEMA not per-site or per-wrapper; token presence not liveness; the phantom direction unchecked (#777); a second `setupFiles` entry could discharge; and plugin-level population integrity borrowed from the sibling guard.

A force-push H1 -> H2 -> H1 spanning `pr-changed-files.sh`'s paging leaves its final
`.head.sha` comparison equal while the middle pages came from H2, so a mixed file list
could produce a docs-only exemption `success` no single head ever justified. The base
alias had been fenced since #706 by a monotonic `change_target_branch` count; the head
axis had nothing, and three contracts asserted otherwise.

`count_retargets` becomes `count_pr_mutations`: one timeline walk, two tallies, one shared
trust flag, a separate fence arm and diagnostic per axis. The advisory hook re-reads
`.head.sha` at the same hoist and off the same response as the base re-read. All three
overclaiming contracts are corrected, plus four paraphrases the first sweep missed.

Measured, not assumed: Gitea 1.27.1 still serves no `files` on `compare/{base}...{head}`;
every push is a `pull_push` event and its count cannot alias; PR #761 really went
`8798a1d -> 830a407 -> 8798a1d`; and Gitea creates the push comment BEFORE emitting the
synchronize notification, so a run cannot abstain on its own trigger.

Two pre-existing fail-opens in the shared walk were found by review and fixed: an empty
ARRAY first page was trusted on any page while the `null` arm required `page > 1`, and no
row was validated before `.type` was selected on.

NOT closed, and documented rather than overclaimed: the walk's `null` terminator is
defeatable, because Gitea pages before it filters (#870). The fence closes the ABA on a
timeline with no truncating block, not the ABA outright.

Closes #786 and #789, bundled because working either alone would build the artifact the other removes.

Every job in all six tracked workflows declares `env.CI_JOB_ROLE` (guard/report-only/none); the
`docker-build.yml` jobs also declare `env.CI_EXECUTION_CLASS` (toolchain/bare-runner). Both guard
populations derive from those markers; the `TOOLCHAIN_JOBS`/`BARE_RUNNER_JOBS` literals are deleted.
A missing or unrecognised marker is a hard failure in both checkers.

#789's literal had a real justification — set equality between two DERIVED sets is blind to a member
leaving both at once — so the marker is the anchor that replaces it, and the cost (proximity to the
`container:` block) is paid by a THIRD derivation from each job's own steps, which is also the only
check that sees the failure #789 filed: a .NET step moved into a bare-runner job, where no set
changes. The residual is disclosed: drop the block, flip the marker AND hide the tool behind a
script and all three go blind, bounded by the failure mode being a loud missing-binary crash.

#786's guard jobs join a machine-checked population: a new `test_workflow_job_guards.py` asserts set
equality both ways against a new "Workflow-job guards" table, and the four jobs with no dropped-step
guard each carry a recorded decision.

Two issue claims were refuted by measurement: #789's "editing docker-build.yml re-points the pin"
(the pathspec is `docker/ci` only) and #786's job count (17, not 15).

Four cold adversarial review rounds across two model families; rounds 1-3 BLOCKED, all findings
fixed and each fix demonstrated by reproducing the reviewer's own test. The recurring defect class
was prose drifting from code, including a mechanism claim in the decision record that execution
refuted. All five mutation proofs redden when their shipped detector is disarmed.

New decision record: `testing.workflow-declares-its-own-job-metadata`.

Records `testing.verification-code-needs-its-own-proof`: the proof obligation follows the
VERDICT rather than the file, so it binds harnesses, wrappers, timeouts and checkers — not
only the files the guard population derives.

The issue asked for a stated position on whether non-guard checker scripts get mutation
proofs. The position as first written claimed `scripts/mcp_smoke.py` "cannot participate"
because driving it needs the gitignored `.mcp.json` and a cold-built language server. Cold
review refuted that by execution: it takes its config path and server name as positional
arguments. The record had failed its own headline rule on the one claim its decision rested
on, so this ships the proof instead of the exemption.

- `scripts/tests/test_mcp_smoke.py` — a hermetic stub JSON-RPC responder and six cases
  pinning the defects the checker has already had, with the positive control as a fixture
  the refusal tests depend on, so a node-id or `-k` selection cannot skip it.
- A declared clause in `mutation_manifest.py` targeting the unguessable request id, using
  the `guard=test / target=script` shape that already exists for `mutation_harness_lib.py`.
  Witnessed red: `id_init = 1` makes the pre-answer accepted at `initialize` (rc 9 -> 10),
  and only that test moves.

`mcp_smoke.py` still gets no inventory row — one is rejected as a phantom (measured). The
row goes to the test file, which joins the derived population automatically.

Five cold-review rounds, four BLOCKED. Round 2 caught a `ruff format` red that would have
failed `script-tests`. Rounds 3-5 found only hand-maintained counts and uniqueness claims in
prose, three of them created by the previous round's fix; that class was deleted rather than
corrected again, per this record's own stop-and-subtract rule.

Docs updated in the same PR: `docs/README.md` task-signal map and `docs/guard-inventory.md`
(row, summary counts, scope-limit item 6).

CI's `Script lint and tests` job went red. Cause: I never ran ruff locally,
which this repo's Python convention requires after any .py change.

  - E741 twice: `l` as a comprehension variable in the sort-order guard.
  - `ruff format --check`: the file was correctly formatted on `main`; my edits
    broke it. One of them left a docstring line at column 0, which `ruff format`
    then "corrected" by over-indenting the rest of the paragraph — repaired at
    the source rather than accepting that rewrite.

Verified the way CI does: local ruff is the pinned 0.12.11, and both
`ruff check` and `ruff format --check` run under bash over the full tracked
population (`git ls-files -z '*.py' '*.pyi' '*.ipynb'`, 46 files) are clean.
The population is counted, not assumed — an empty glob would pass vacuously,
which is the failure `scripts/tests` guards against elsewhere.

`scripts/tests` 1097 passed, 2 skipped after the reformat.

Population derived from `git ls-files`, not the issue's 9-key list (~21 claim sites).

Re-confirmed unchanged on 1.27.1: the distinct `skipped` commit-status state; `compare` serving
no `files`; no agent-side cancel route (REST route + swagger only); `branches: [main]` suppressing
the run off a non-main base.

Newly measured on four throwaway scratch bases, `main`'s rule never PATCHed: an absent required
context blocks an ORDINARY merge without needing `block_admin_merge_override` (that field governs
the FORCE path only), and `enable_bypass_allowlist` with an empty list is NOT a substitute for it.
Trap recorded: the PR API reports `mergeable: true` while such a merge is refused.

Left explicitly dated with reasons: push-supersession auto-cancel, `pull_request_target` overlap,
`--depth=1` no-merge-base, and the scope-enum/`reqRepoWriter`/403 items. Not a corpus sweep, and
`ci.actions-credential-scoping` now says so. `review-verdict.yml` untouched — #763 holds that file.

Five adversarial review rounds (21/12/9/6/2). Caveat: all same-model-family; Codex was rate-limited.

A sixth cold review found everything in round 8 clean except one line, and it
is the rule this branch keeps rediscovering: the test pinned the new
`raced_why` only by asserting the ABSENCE of the borrowed wording. Measured —
replacing the string with `zzz` left the suite green while an operator would
get `::error::… — zzz.` beside a sticky sentinel. The sibling test 330 lines
away states the rule and follows it; this one did not.

Now asserted positively, with the em-dash and full stop discriminating the
`::error::` reason from the `::warning::` text that continues ", which cannot
be true". The `zzz` mutation reddens it.

Three nits from the same review, all verified by execution rather than reading:
  - the earlier fixture's row was excluded by the strict `> $since` because the
    mark became its OWN id, not because it sat below the mark.
  - the predecessor comment said `main` "warned only on `null`". True of the two
    EMPTY shapes being contrasted; an empty body and a non-array object warned
    as well. Scoped.
  - `docs/ci-cd.md` and the record described the `::error::` as a two-way split
    (found vs unverifiable). Round 8's whole argument is that a complete read
    returning an IMPOSSIBLE answer is a third case, not a variety of the second
    — which is the operator-facing point, since it decides whether to go looking
    for an API failure that never happened. Both now say three.

The review re-verified, by comment-stripped diff, that round 8 changed no
executable line beyond the `raced_why` string and the if/elif restructure, and
independently reproduced both inertness measurements and the `origin/main`
predecessor behaviour.

Verification: `scripts/tests` 1097 passed, 2 skipped; decisions_validate and
build_decisions_catalog --check exit 0.

timothyandClaude Opus 5 4164efbc3e fix(763): round 8 — a fixture must pose the scenario it narrates
A fifth cold review confirmed the gate's behaviour is correct and proof-backed,
and blocked on three non-behavioural items. All three fixed; none touches the
shipped logic.

MEDIUM — the round-7 fixture narrated a raced human verdict it did not
construct. `null-page1-after-post` appended the row unconditionally, so it also
joined the PRE-write read and lifted the high-water mark above itself; removing
it changed nothing. The reviewer's suggested fix was to gate the append on the
post-write read. Measured after gating: still inert, because page 1 answers
`null` before any row reaches the wire.

So the row is gone rather than gated, and the prose now describes what the
fixture actually poses: a response asserting an empty history for a sha this job
wrote to must not be accepted as proof that nothing raced. Whether a verdict
really raced is not modelled and does not need to be — the response is not
evidence either way. A row the test cannot observe is decoration that reads as
coverage, which is the same class this branch has now been blocked on five
times.

LOW — the comment claimed the predecessor "at least produced a `::warning::`".
Half false, measured against `origin/main`: its `jq -e 'type == "array"'` gate
ACCEPTED `[]` silently and warned only on `null`. What is actually new is that
the paged walk reports such a read as a SUCCESS.

LOW — when the empty clause fired it set `ph_ok=no`, so the log said "could not
be read completely" beside a walk that completed on a validated terminator. The
answer was impossible, not unreadable, and an operator holding a sticky sentinel
needs to know which. It now carries its own `raced_why`, asserted by the test.

Both clauses mutation-proved: disarming the empty check, and reverting to the
borrowed wording, each redden the named test.

Verification: `scripts/tests` 1097 passed, 2 skipped; decisions_validate and
build_decisions_catalog --check exit 0.

timothyandClaude Opus 5 e6f04cc739 fix(763): round 7 — reject an empty post-write history, and the fourth overclaim
A fourth cold review returned NOT-MERGEABLE on two Mediums. Both fixed, plus
its three Lows.

MEDIUM, and a defect this branch introduced. Tolerating a `null`/`[]` page 1 as
"complete, zero rows" is correct for the PRE-write caller — a head nothing has
posted to genuinely has no statuses — and impossible for the POST-write one,
which has just written a row to that sha. The body is well-formed, so nothing
retries it, and the walk reports success: `raced=0` concluded from a list that
cannot be real, on the one path whose failure direction is toward SUCCESS.
Worse than the code it replaced, which at least emitted a `::warning::` — a
logged fail-open had become an unlogged one. Reviewer measured both directions.

The post-write caller now rejects an empty result itself; the walk stays
caller-agnostic because the pre-write caller genuinely needs the empty answer.
This is NOT the withdrawn currency witness: that asked whether ANY row sat above
the mark, which an unrelated newer row satisfied while the rejection stayed
hidden, and it fired on schema-valid staleness. This asks only whether the list
is EMPTY — a state no unrelated row can produce and no ordering can disguise.
It carries neither defect. Proved by fixture; disarming it reddens the named
test, and the previously-uncovered `null`-at-page-1 clause is now covered too.

MEDIUM — the fourth overclaim of the same class, in the decision record body:
"Uncertainty must fail closed at both ends … Both repair now." The page-2 probe
was DELETED, not converted; it repairs nothing. It also contradicted the
record's own `rule:` ("the two directions are NOT symmetric") and the bullet
directly beneath it. Round 5 retracted this wording in `docs/ci-cd.md` only —
the sweep was by subject, not by the retracted words.

Also fixed:
  - the record presented "an empty FIRST page is legitimate" as a property of
    the walk; it is a property of the pre-write caller.
  - `docs/ci-cd.md` called the numeric-only id comparisons a fix for mark
    inflation; they are a TYPE guard, closing the string half. A corrupt but
    genuinely numeric id still inflates the mark — not attacker-controllable,
    since ids are server-assigned, and now stated rather than implied.
  - `test_a_partial_mark_is_SAFE...`'s self-guard promised to detect that the
    fallback ran; it keys on a warning emitted by a different condition, so
    deleting the fallback left it green. Its sibling is what reddens; the
    message now says what it actually pins.
  - the order-faithful fixture appended the job's own POST after the reversal,
    serving the NEWEST row on the OLDEST page — the opposite of DESC, in the one
    fixture that exists to be ordering-faithful.
  - "twice per walk" for the wasted sleep; it is once per walk, twice per run.
  - a dead counter read in the DESC mode.

Rebased onto b16ec15d6 (the other session's #781/#799 docs work; no file
overlap, no conflicts).

Verification: `scripts/tests` 1097 passed, 2 skipped; fifteen executed mutations
across rounds 2-7; decisions_validate and build_decisions_catalog --check exit 0.

timothyandClaude Opus 5 89db6022d9 fix(763): round 6 — measure the partial-mark fallback under the REAL ordering
A fourth cold review (Opus, isolated worktree, tests/double/docs focus)
reported no correctness bugs in shipped behaviour but two coverage defects on
exactly the two things this change advertises. Both are closed.

The partial-mark fallback's safety is a claim ABOUT THE ORDERING — page 1 holds
the newest rows, so a walk that fails later still saw the true maximum. The
fixture pinning it served ASCENDING ids, i.e. the arrangement the design calls
unsafe, and passed anyway because the raced row's id sat above even the partial
mark. It could not distinguish safe from unsafe.

The stub now HONOURS the sort parameter: order-faithful modes serve DESC by
default and ASC when the request asks. The new fixture holds a PRE-EXISTING
base-mismatched verdict at id 7055 among 60 rows. Under DESC the salvaged mark
is 7059 and that row is below it — the exemption correctly stands. Under ASC
the mark would be 7049 and that untouched row tests as NEWER, a sticky repair
on a head nothing raced. So re-adding `sort=highestindex` now reddens by
BEHAVIOUR, not only by the structural assertion added in round 5. Measured:
re-adding it reds both tests.

Most modes stay ordering-blind on purpose and now say so: they test walk
COMPLETENESS, which is order-independent, and insertion order is what lets a
fixture place a row beyond page 1.

Also fixed:
  - `null` is accepted as an empty page. An array-only gate is the exact shape
    of #751 — `count_retargets` had one, the timeline really did return `null`
    past the end, and the fence withheld EVERY exemption from the day it
    shipped. The same narrowing here is worse, because this walk's failure is
    the STICKY sentinel: every exempt PR would need a hand-posted verdict, per
    head. Tolerating `null` cannot misread `[]`. Proved by fixture.
  - the fail-closed comment said "past the 1000-row page cap"; the bound is 950,
    as the walk's own comment and both docs already said.
  - the docs claimed "only a read returning no rows at all abandons the mark".
    False: a VALIDATED empty history yields a mark of 0 and is not abandoned —
    that is the normal first run. What abandons it is a read that both FAILED
    and returned nothing. Corrected in ci-cd.md and the record `rule:`.
  - a comment pointed at the page-2 probe "a few lines further down"; it was
    deleted, so the deixis pointed at nothing.
  - the stub claimed its logical-read counter "is only reached on a SUCCESSFUL
    page-1 serve" — measured false; it counts page-1 requests, retries included.
  - five `(round N)` markers removed. A round number is session chronology and
    does not parse for a reader who never saw it (`docs.no-session-narrative`);
    an issue number does. The four that remain predate this change.

Verification: `scripts/tests` 1096 passed, 2 skipped. Thirteen executed
mutations across rounds 2-6. The reviewer independently re-ran the earlier
matrix and confirmed it, with one correction carried here: two of those
mutations redden MORE than their named test, so "each reddening exactly its
named test" was wrong — they redden at least it.

timothyandClaude Opus 5 53ee44cbc1 fix(763): round 5 — correct the overstated motivation, and fix the string-id twin
A third cold review (Opus, isolated worktree) returned NOT MERGEABLE with one
High and three Medium. All are addressed.

HIGH — the stated motivation was wrong, and self-contradictory once round 4
landed. Under the server default (`created_unix DESC`) page 1 holds the NEWEST
rows and ids are monotonic with `created_at`, so page 1 already carried the
true maximum id AND every row newer than the mark — the only rows the
post-write check selects on. A single-page read therefore missed a raced
verdict only if more than 50 rows were created INSIDE the write window, not
merely on "a head with more than 50 rows", which the issue, the comments and
the docs all asserted. Reviewer executed an order-faithful DESC stub: a
page-1-only reader repairs identically to the full walk.

What actually removed #761's stall is retiring #751's page-2 probe, not the
paging. The walk still earns its place, for a reason now stated instead of the
false one: it stops the gate's one fail-toward-SUCCESS path depending on an
undocumented ordering the server honours only coarsely (page 1 came back
`114,112,113,111,110`). That measurement was deleted in commit 1 and is
restored, since round 4's safety argument rests on exactly it.

MEDIUM/real defect — the string-id TWIN, live on `main` and one expression
away from the fix already made: `select((.id? // 0) > $since)`. jq orders
strings above every number, so a PRE-EXISTING row with `"id": "3"` reads as
newer than any mark, is counted as having raced the write, and gets the sticky
sentinel plus a false "was overwritten" on EVERY later run — a permanent
per-sha stall no re-trigger clears. Now numeric-only, with a test.

Also fixed: a non-empty history carrying no numeric id was collapsed to a mark
of 0 (making every pre-existing row look newer); it is now reported unusable
and the check is skipped. `sleep` no longer fires after the final attempt.

Three unpinned clauses now have tests, each proved by an executed mutation:
  - the page cap is a refusal, not a terminator (1050-row fixture)
  - the `::error::` found-vs-unverifiable distinction (forcing `raced_why=human`
    reddened nothing before)
  - the walk requests no sort order — a structural guard on round 4's
    withdrawal, which nothing mechanical protected. It reads request LINES, not
    comments, since the withdrawal note names the parameter to explain it.

Honest scoping, not new code: the test double is ordering-blind, so the paging
tests prove WALK COMPLETENESS, not that a real raced verdict would otherwise be
missed — under DESC it would not be. The stub comment and the docstrings now
say so rather than implying the stronger claim.

Docs: `ci-cd.md` and the record's `rule:` carry the corrected reachability, the
DESC dependency of the partial-mark fallback, and both rejected alternatives
stated as rejected alternatives rather than as draft chronology
(`docs.no-session-narrative`).

Verification: `scripts/tests` 1094 passed, 2 skipped; eleven executed
mutations across rounds 2-5, each reddening exactly its named test;
decisions_validate and build_decisions_catalog --check exit 0.

timothyandClaude Opus 5 007d2fd3df fix(763): round 2+3 — close the fail-opens the paging change introduced
Two independent cold reviews (Codex GPT-5.6 cross-family, and an isolated
Opus agent) converged on the same blocker, which is fixed here along with
everything else they found.

BLOCKER — the mark walk turned a fail-closed case into a fail-open. The
high-water mark gates the post-write race check entirely: `max_id_before=-1`
skips it. Before paging, only a failure of the single page-1 request could
reach that. Requiring a COMPLETE walk newly routed a page-2 hiccup, an
over-cap history, or one malformed id on a later page into the same hole, so
a human rejection racing the write was left green where `main` repaired.
A partial list now still yields a mark: it can only be LOWER than the true
maximum, which makes the check more eager, never blinder. Only a read
returning no rows at all abandons it — the pre-existing #849 gap, unchanged
and now asserted by a test so it stays visible.

WITHDRAWN — the "currency witness". It produced two defects from one
mechanism, which is the signal to remove rather than patch twice: counting
ANY row above the mark does not witness this job's write, so a stale-but-valid
snapshot carrying an unrelated newer row passed while hiding a rejection; and
a schema-valid stale read is not retried, so one such response turned a
transient anomaly into a permanent sentinel. The hazard has no mechanism here
either — Gitea is a single instance with no read replicas. Removing it
restores the pre-change exposure on that path, a non-regression.

Also fixed, each a fail-open with a fixture and an executed mutation:
  - `.creator` is type-tested before indexing. `.creator.login` on a non-object
    exits jq 5 and `set -e` took the step down after the green was posted and
    before the repair. Reproduced by both reviewers.
  - the mark is the max over NUMERIC ids only. jq orders strings above every
    number, so one `"id": "99999"` passed the numeric gate and inflated the
    mark until nothing looked newer.
  - an unusable `raced` count now repairs instead of "not acting on it".
  - `sort=highestindex` (ASC, measured) so a row inserted mid-walk appends at
    the end rather than at position 0 on a page already read. An unknown sort
    value silently falls back to DESC, so this is insurance, not load-bearing,
    and the comment says so.
  - `ph_ok`/`ph_rows` renamed off `read_existing_verdict`'s `st_ok`. No live
    bug, but a name collision in a 1400-line step.

Tests the reviews showed were missing, each proved by an executed mutation:
  - verdict beyond a SHORT page (a deliberately unfaithful truncated response
    — against a faithful double a short page is always the last, so the rule
    "terminate only on an EMPTY page" was unobservable)
  - pre-write paging failure still yields a usable mark
  - pre-write read returning nothing abandons the mark and says so
  - a TRANSIENT page failure is retried (the retry was unproven code: every
    other error mode fails on every attempt, so disarming it reddened nothing)
  - a string id cannot inflate the mark
  - a malformed `creator` row does not kill the job

Stub corrections, both the same class as the earlier `[]`-vs-`null` gap: it
served one flat list (so paging was unobservable) and computed its own-post id
with `max()` over mixed str/int, which raised TypeError and made the string-id
test pass because the DOUBLE crashed rather than because the mark was right.

Mutation matrix, all executed, each reddening exactly its named test: retry
disarmed; numeric-max reverted; partial-mark fallback removed; short-page
terminates; page-1-only walk; post-write fail-closed flipped open; jq
type-guard reverted. The unusable-count arm is unreachable by any fixture and
is annotated as such rather than claimed as proved.

Verification: `scripts/tests` 1090 passed, 2 skipped; decisions_validate and
build_decisions_catalog --check both exit 0; terminator, clamp, sort order and
id monotonicity all re-measured live on Gitea 1.27.1.

timothyandClaude Opus 5 4368cc8cbe fix(763): page both /statuses/{sha} reads to a validated terminator
`review-verdict.yml` read the per-POST status history twice with a single
`?limit=100` request. `limit` clamps to the server-wide `MAX_RESPONSE_ITEMS`
(measured 50), so on a head carrying more rows than the clamp both reads saw a
partial list. The high-water mark was only page 1's maximum, and — the direction
that matters — a raced human verdict beyond page 1 was invisible to the
post-write race check, leaving a forged green over a rejection.

Both reads now walk to a validated empty page (`[]` on this endpoint, measured
2026-08-28 against PR #761's 114-row head: pages 1-2 return 50, page 3 returns
14, page 4 is `[]`), never terminating on a short page, under a 20-page cap and
retrying each page once. Correctness does not depend on the cap value.

This retires #751's page-2 "assume raced" probe, which repaired every head that
outgrew one page. It fired on Renovate PR #761: an `::error::` claimed a human
verdict had been overwritten on a head carrying none, and the sticky sentinel
then refused re-exemption on every later run.

Two properties replace it. Uncertainty now fails closed at both ends — the
unreadable-history branch warned and left the exemption green while the page-2
probe repaired on the same uncertainty, one check disagreeing with itself; this
is affordable only because paging removed the common trigger. And the post-write
read must witness the job's own write: reaching a validated empty page proves the
walk finished, not that it saw a current list, so at least one row above the
pre-write mark must exist because the job just posted one.

The `::error::` now distinguishes a verdict actually found from an unverifiable
read. The sentinel description stays generic — the classification recognises it
as a fixed point, so its wording is load-bearing.

The stub gained faithful paging (50-row slices, `[]` past the end, one snapshot
per logical read so a counter mode cannot describe two different histories across
pages) and, separately, modelling of the job's own POST appearing in the history
— which it had never done, so in its world every ordinary run looked like a head
nothing had been posted to. `own-write-invisible` withholds exactly that detail
as the negative control for the currency witness.

Mutation-proved by execution, one clause at a time:
  - walk reads page 1 only -> RUNNING_PAST_PAGE_1_is_PAGED_and_the_exemption_
    STANDS, raced_verdict_on_PAGE_2_is_detected_and_repaired and both UNREADABLE
    history tests go red
  - currency-witness zero branch deleted -> CANNOT_SEE_OUR_OWN_WRITE red
  - fail-closed flipped to fail-open -> both UNREADABLE history tests red

Verification: `scripts/tests` 1085 passed, 2 skipped; decisions_validate and
build_decisions_catalog --check both exit 0.

Closes the push route into ci-image.yml (#744) and ships the persist-credentials guard that was waiting on it (#835).

ci-image.yml's push trigger had no branches: filter and was path-scoped to docker/ci/** AND to the workflow file itself. Gitea resolves a push workflow's definition from the pushed ref, so any branch push touching those paths ran that branch's own YAML on a docker-capable runner holding the credential that writes ersatztv:prod and the ersatztv-ci:<sha> five container: jobs execute.

Be precise about what the filter buys: it is loaded from the pushed ref like the rest of the file, so a branch that deletes it re-enables the route. This closes the DRIVE-BY case - publication as a side effect of an ordinary push - and is not a boundary against a writer who intends to run their own YAML. The wider class is #853.

The self-reference left both paths: and ci-image-pin's expected in the same change - a decided tradeoff with both prices stated, not a necessity. Branch publishing moves to workflow_dispatch, probed live: run 2340 on this branch published ersatztv-ci:43b1e45 and left :latest unchanged.

With both mechanical blockers gone, ci-image.yml's checkout takes persist-credentials: false (16 of 16) and scripts/tests/test_workflow_persist_credentials.py holds the convention with NO exemption list - git-index population, declared clause mutation re-run every suite, guard-inventory rows.

`review-verdict.yml` decided whether an existing `review-verdict/h10` was worth INHERITING by
testing `.creator.login != null` — satisfied by any account's credential, including the `renovate`
bot's `RENOVATE_TOKEN`, a `write:repository` PAT that cannot be scoped down the way #697 scoped the
registry credential. The test is now membership in `H10_REVIEWERS="timothy"`, a literal in the
base-resolved definition.

The design that survived 11 cold review rounds:

* `read_existing_verdict` carries TWO flags. `ex_human` (attributable AND allow-listed) gates
  INHERITANCE; `ex_attributable` gates the last-moment re-read, which asks the opposite question and
  must stay broad. Narrowing both — the first draft — makes the job post its exemption over a
  mid-run rejection, and the post-write repair does not cover that.
* The two calls no longer compute an identical predicate, so "changed" is made explicit: the
  state/creator/description triple from the first read is snapshotted and compared.
* The allow-list governs an inherited `success` ONLY. An existing `failure` inherits on
  attributability alone, because inheriting a rejection can only withhold an exemption while
  re-deriving one can turn it green on an exempt PR. A symmetric rule was a measured fail-open.
* The post-write raced check stays broad — not because narrowing would let a rejection go green
  (a real reviewer is on the list by construction), but for the misconfiguration case.

Two mechanisms were WITHDRAWN rather than patched a third time, and both withdrawals are recorded
in `ci.exemption-provenance` so they are not re-attempted: a `::warning::` annotation that produced
three defects in three rounds, and a post-write fix whose generic `pending` would have been
re-derived anyway and which had no retry trigger.

Verified: the inheritance predicate driven against the LIVE Gitea API on a probe-named context,
both allow-list directions; every clause mutation-proven against the shipped file; `scripts/tests`
1012 passed, 2 skipped.

Follow-ups filed: #845 (post-review-verdict.sh does not check its own account is allow-listed) and
#849 (post-write verification: three routes leaving an exemption `success` over a human `failure`,
plus the retarget fence's post-POST gap, plus the prose sweep that lands with the behaviour).

The verdict words lived in two hand-written shell copies — the `case` arms of
post-review-verdict.sh (write) and the POS_RE/NEG_RE regexes of
check-review-verdict.sh (read) — held together by nothing but a comment that had
already gone stale. scripts/lib/review-verdict-vocabulary.sh now declares them
once and both sides derive; neither script enumerates a verdict word any more.

Only the WORD SET moved. The grammar stays in check-review-verdict.sh, where
every #629 false-open actually lived.

No parity test: #774 shipped one and withdrew it after six rounds, because a
regex over shell source is not a shell parser. The proof is behavioural and
graded MUTATION — the harness restores the pre-#788 hardcoded POS_RE each run and
requires it to redden.

Enforcement is a DATA dependency, not a control-flow gate. Review round 1 found a
real fail-open in the first commit: `${#arr[@]}` is nounset-safe only for a
declared-empty array, and under `set -u` that error inside a function called as
`if ! validate` skips BOTH branches — so on the reader (deliberately no `set -e`)
an explicit BLOCKED @ head classified `positive`, exit 0. Validation now sets a
sentinel on its last line and the derived views refuse without it.

Six cold review rounds; rounds 2-6 found no fail-open across differential fuzzing
(4788 / 2612 / 7560 payloads, zero divergences from origin/main's grammar),
sentinel forgery, environment poisoning, declare -p evasion on bash 5.3 and 3.2,
path/symlink resolution and probe TOCTOU. Every malformation fails closed: reader
exit 2, writer exit 1 with nothing posted.

Also corrected: CLAUDE.md and release.review-verdict-gate both enumerated the
vocabulary without LGTM, a word the code has accepted since #629.

timothy 8c72a5de9e docs(772): correct the twins of two claims this branch already fixed
Both remaining review findings were the same shape as the one before them, and it is the
shape this repo keeps recording: a claim corrected in one place, its copy left standing
somewhere else in the tree.

  * `docs/ci-cd.md` said "gates nothing" in the small-lane paragraph while the section 1441
    lines below said the opposite. A red preflight lands in the PR's combined status, which
    the merge gate reads (#598) — what it does not do is SKIP the jobs it diagnoses, and
    that is now the sentence in both places.
  * Two docstrings in the preflight's test file still described the disarmed script as
    warning and exiting 0. Built the mutant and ran it: it emits an error and exits 1. The
    exit code separates nothing now that an unverifiable answer fails too — the DIAGNOSTIC
    is what the mutation destroys, which is what `mutation_manifest.py` already said and
    the prose next to it contradicted.

Nits from the same pass: the admin-cron URL is quoted (`?` globs in zsh, the operator's
shell); the retry assertion's message quoted a threshold it does not use; the arm table
omitted the malformed-credential shape the code and tests both have; `buildx inspect` no
longer `--bootstrap`s a builder just to read its name, and an empty capture no longer
produces a noisy `buildx use ""`.

Swept the tree for the shape rather than the two reported lines: the surviving "exits 0"
and "could-not-tell" hits are other subsystems, or the concept named as a concept.

timothy 30640bb780 fix(772,792): close the fix-round review — the doc still described the semantics the fix reversed
The re-review's one HIGH was mine and was the obvious one to miss: the previous commit changed
the preflight so an unverifiable answer FAILS, and left a `docs/ci-cd.md` paragraph two
screens away still saying "anything else is reported as could-not-tell". That paragraph is
the one an operator reads when the job goes red, and it would have talked them into
reinstating the defect. Replaced with the full arm table, including the two rows the first
draft got wrong and why.

  * "gates nothing" was false in the way this repo has recorded before (#598): the
    merge-consent hook reads the COMBINED status, so a red preflight blocks the merge like
    any other red job. It does not SKIP the jobs it diagnoses; that is the accurate claim,
    in ci-cd.md and in the remote-state row.
  * The production retry defaults were evaluated by nothing — every test overrode both
    knobs. A test now drops the overrides and measures three attempts and a real pause, so
    editing the default to 1/0 (which would falsify the "a blip does not redden a PR"
    argument) goes red.
  * `journalctl -u gitea | grep ExecuteCleanupRules` is not a reproduction: that identifier
    reaches the log only through slow-query warnings, so an empty grep on a healthy host
    reads as "the rule never ran" — the inverse. Replaced with the admin cron API, which
    answers deterministically.
  * The recovery recipe's `docker buildx use default` needs the containerd image store to
    `--push` (both named hosts have it, checked today) and mutated the operator's builder
    selection without restoring it.
  * The stub's comment claimed both halves of real curl's transport failure mattered; only
    the exit status is observable, because `|| resp=""` discards what curl printed.
  * The empty-half credential refusal echoed the username; it needs no value at all. The
    401/403 arm aborts the remaining pins while 404 continues — deliberate, now stated.
  * `curl -u "$VAR"` puts a credential in argv, and this job runs container-free on a shared
    host. NOT fixed here: it is the shape all five `scripts/` callers already use, so fixing
    one site leaves the class and splits the codebase. Filed as #821 and named at the site.

Two independent reviewers (one cross-family) converged on the same defect, and it was the
important one: the preflight WARNED and exited 0 on every answer that was not 200 or 404,
so a missing `curl`, a moved registry or a DNS change would have left it green forever —
"the check could not run" presenting as "the pin is fine", in a script whose own header
disclaimed exactly that. Unknown answers are now retried (3x, 5s) and then FAIL, with
wording kept distinct from the deleted case because the two send an operator to different
places.

  * An absent secret does not arrive as an unset variable. `${{ secrets.X }}:${{ secrets.Y }}`
    interpolates to ":", a perfectly non-empty and perfectly useless credential, and the
    tests covered only the unset shape. Both halves are now required, and the parametrised
    test drives the production shape.
  * HTTP 200 is not a manifest. A proxy or a login page answers 200 too, so the body is
    fetched and matched for `schemaVersion` (a shell `case`, so no jq dependency and no
    pipeline that can inject).
  * The curl stub ignored `-u` and answered 200 regardless, so deleting the real `-u` would
    have left the suite green while the live registry rejected every request. It now 401s an
    unauthenticated read, as the registry does.
  * The mutation's declared diagnostic changed with the script: now that unknown fails too,
    the exit code no longer separates "deleted" from "could not check", so the proof turns on
    the message and `expect` says so.
  * docs/ci-cd.md: `scan` is no longer the only `docker-build.yml` job on the small lane, so
    the tag-push exclusivity claim and the lane membership were both false. Fixed.
  * "Immutable" was overstated: `ci-image.yml` tags `rev-parse --short HEAD`, so a dispatch or
    a weekly no-cache run at the same HEAD republishes that tag from a rebuilt image. Stated,
    along with what the rebuild recovery does NOT restore (mutable bases and apt, so equivalent
    rather than bit-identical).
  * The recovery recipe left you in a worktree checked out at the pin commit — where the
    verify script does not exist, and where the workflow carries the pre-bump pin. It now
    keeps `$repo`, returns, and removes the worktree. It also needed BuildKit's `http = true`
    caveat: the container driver does not inherit the daemon's insecure-registries.
  * The root cause carries its evidentiary limit and its reproduction commands, and says what
    to conclude if a pin vanishes after server-management#842 lands (refuted, not re-applied).
  * The `ci.required-job-step-execution-markers` carve-out named one container-free job; there
    are two now, and the membership is what rots.
  * The decision record's `''` YAML escapes leaked into rendered prose; "status, no comment ->
    ask" is qualified (a prior positive verdict for the SAME head still satisfies condition
    (c)); "exits 1" is "exits non-zero" (usage exits 2, jq its own status, signals 128+n).

timothy 5ba442c11c fix(772,792): name the missing toolchain image, and stop a refusal leaving a verdict comment
#772 — the pinned CI toolchain image can be deleted out from under us, and when it was
(2026-08-11..13) all five `container:` jobs died at image pull, both required contexts
included, with the cause buried in each job's log. Root cause is registry-side and is now
established rather than guessed: an owner-level Gitea package cleanup rule (keep_count 15,
remove_days 1, remove_pattern `.*`, keep_pattern no 7-hex sha can match) deletes a sha tag
once 15 newer versions exist, and `ExecuteCleanupRules` ran nightly through the window. The
`ersatztv` package carries the same rule's fingerprint exactly — every sha tag older than
the 15-slot window is gone, every keep_pattern tag back to 26.3.1 survives. Version deletes
leave no audit row, so the specific run cannot be replayed; that limit is stated where the
claim is made. The durable fix belongs to the registry's repo: server-management#842.

What lands here is what a consumer of someone else's registry can do:

  * `toolchain-preflight`, a container-free job (a job consuming the image could not run to
    report it missing) resolving every pin against the registry and failing with a message
    that names the tag and the recovery. Not a `needs:` of the jobs it diagnoses — gating
    five jobs behind a checkout and one curl taxes every green run to speed up a rare red
    one, and they already fail fast.
  * Only HTTP 404 means gone. Everything else is could-not-tell, and rejected credentials
    fail rather than pass as unknown — "the check could not run" must never present as
    "the pin is fine".
  * A recovery path that does not need CI: rebuild the SAME tag from the commit it names
    and push it. The push half was verified against this registry on 2026-08-22 with a
    throwaway package (created, resolved 200, deleted).

#792 — the reported defect was the exit code, and re-measuring says that premise is false:
every no-status path already exits 1, and eight refusal modes now assert it against the real
predecessor, where they pass. The observed 0 came from the invocation, not the script. What
WAS broken is the half-state the issue describes second: the comment was written before the
status, so every refusal left `Review-verdict: MERGEABLE @ <head>` on a PR with no gating
status behind it. The two writes are now ordered status-then-comment, which makes the only
reachable half-state the safe one — a status with no comment leaves the merge hook's
condition (c) with nothing to classify, which is an `ask`. The refusals themselves are
untouched. Ordering rather than compensating deletion: an orphaned-comment cleanup needs a
Gitea call, and these refusals are usually caused by Gitea being unreachable.

Proof for the ordering is the split against origin/main's script: the 8 orphan/ordering
tests go red there, the 8 exit-code tests stay green.

`testing.guard-derives-population-from-source` (#774) was silent on the commonest
population in our own guards — files in a directory — and every one answered with a
filesystem walk. A walk is not authoritative: it reports build output, generated
shims and editor droppings, and differs per machine. #778 measured the cost by
getting the same population wrong three times in one PR.

CONVERTED (a completeness claim over tracked files): `test_guard_inventory.py`,
`test_hook_fire_log.py`, `test_ci_image_pin_population.py` (which also gained
`*.yaml`), `test_remote_state_inventory.py` (folded onto the shared derivation), and
`test_pr_changed_files.py` (not on the issue's list — found by sweeping the whole
repo).

ASSESSED AND RECORDED, not silently skipped: `_repo_copy` takes its file list from
the index for hermeticity though it makes no completeness claim;
`test_ci_dropped_step_guard.py` has no filesystem population at all; the decisions
corpus is recorded as unexamined rather than cleared; and the SPA page-size guard is
deferred to #819 with its obstacle documented. This is not "replace every glob".

`scripts/tests/tracked_files.py` is the single derivation.
`test_guard_populations_derive_from_git.py` proves it in two measured complements:
exhaustive removal catches a hardcoded `.exists()` admit and memoisation; the call
log catches an append-only source that yields nothing on this machine — #778's
shape — which removal cannot see because it has nothing to remove.

Twelve rounds of independent cold review, alternating model families in isolated
worktrees. The production derivations were confirmed sound every round; every
blocking finding after the first was in the proofs or in prose claims about them.
Counts over growing populations were removed rather than corrected, after three
drifted.

Every `MUTATION` row of `docs/guard-inventory.md` now carries a DECLARED clause mutation that is applied to an isolated copy of the repository on every suite run, with the row's own named test required to go red carrying a declared diagnostic. Manifest and MUTATION rows are compared for set equality both directions; the other 22 guards each carry a stated reason, compared the same way.

Measured rather than assumed: 12 of 13 guards admit a single-clause mutation; `instrumentation_faults` does not, and that entry carries the surviving finer mutation, re-run every suite.

Nine cold cross-family review rounds. Rounds 1, 2, 7 and 8 each found real mechanism defects — two mutations that measured nothing, an incomplete git-environment sanitisation, a reset that restored its own mutant, and a proof of that fix which was not itself isolated. All fixed and witnessed red.

#780 and #784 were green separately and red together: the gate landed on a base
that predated scripts/check-doc-narrative.py, so nothing ever ran ruff over it.

- RUF100 x2 on `# noqa: BLE001` — BLE is not in this repo's select, so those
  directives suppress nothing. Enabling BLE instead was measured and rejected: 6
  further sites in decisions_validate.py, whose broad catches are deliberate. The
  non-enabled code is dropped; S110 and both comments stay.
- scripts/tests/test_check_doc_narrative.py was not ruff-formatted.

Verified with the shipped invocation: 35 files, all checks passed, all formatted;
suite 807 passed / 2 skipped.

Python lint here was a property of the operator's laptop: the global instructions
say to run ruff, no workflow ran it, and with no committed config ruff fell back
to whichever ~/.config/ruff/ruff.toml the machine happened to have.

- ruff.toml at the root, pinned ruff==0.12.11 in the script-tests job.
- Both lint steps pass an EXPLICIT population from `git ls-files` with
  `--no-force-exclude`, never `ruff check .` — an `exclude` empties a
  discovery-based run into a GREEN one (top level empties both commands, [lint]
  empties check, [format] empties format --check), and `ruff check .` over zero
  files exits 0 with only a stderr warning. Guarded by an empty-population arm.
- Tree clean: 74 findings at 706674272, 57 fixed in code, 17 per-site noqa with
  reasons inline. S105 deliberately per-site, not a directory blanket. RUF100
  selected so a suppression that suppresses nothing is itself a finding.
- pyright stays ungated; reasoning in the record.

Both steps witnessed red on the runner against the shipped bodies: run 2173 job
9176 (ruff check) and run 2170 job 9163 (ruff format --check).

Docs: new record ci.python-lint-ruff-config-committed, ci.script-tests-job
cross-ref, docs/ci-cd.md (also correcting a stale ~190-tests/~10s figure to the
measured 773 tests / ~4.5 min), docs/defect-shapes-773.md §5.2 resolved.

Closes the remaining three entries on #785's ranked list with clause-level mutation proofs, each
witnessed red against the real subject in place:

* the `pretooluse-worktree-guard.sh` + `posttooluse-worktree-marker.sh` PAIR — four clauses,
  including the cross-file seam (a clause in the marker hook, asserted against the guard's
  decision) that could not exist while the halves were tested apart;
* `.husky/pre-push:11`'s `unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE` — git exports `GIT_DIR` to
  `pre-push` only from a worktree, which `process.shared-tree-readonly` makes the mandated way to
  work here, so the guarded case is the normal one;
* `scripts/build_decisions_catalog.py --check` — including the `__main__` wiring, which can print
  "is stale" on stderr and still exit 0.

Nine ways the catalog guard can stop gating are detected, judged by executing the step's whole
`run` script rather than by matching lines out of it. Two channels are undecidable outside the
runner and are stated as uncovered rather than guessed at.

Inventory regraded to 12 MUTATION / 6 BEHAVIOUR-ONLY / 16 NONE, with a stated reason for every
remaining NONE row, verified member-for-member against the derived set.

Five cold review rounds; findings closed include production-hook-fire-log corruption, a
tautological assertion, a guard asserting on its helper rather than on the effect, and two false
greens in the workflow extractor. Follow-up: #809.

review-verdict/h10 Review-verdict: MERGEABLE @ 7347a08 (base: main)
Local review returned MERGEABLE — no Blocker, High or Medium, both sentinels verified
pinned by mutation, no regressions. Its one Low is taken rather than deferred, because
it is a one-line fix and because deferring it would leave exactly the shape this PR
exists to document.

A 200 whose body is NOT an array never reaches the classifier: the array gate diverts
it, `bp_code` stays 200, and the generic ask then reported "HTTP '200' — Gitea
unreachable, or these credentials lack the repo-admin scope" about a read that plainly
succeeded. That is the identical defect the previous commit fixed for the
throw-inside-the-classifier arm, one branch earlier — fixed where it was noticed, left
in its twin.

The previous commit's message even generalised the pattern ("a sentinel that doubles as
an HTTP code makes a decision state a cause that did not happen") while covering only
one of the two arms it applies to. The test is now parametrised over all three shapes
that reach an unusable 200 — UNPARSEABLE-RULES, GARBAGE, EMPTY — and reverting the new
sentinel reddens the two that the first fix missed.

Also finishes the de-indent the previous commit claimed: that comment block went from
19 leading spaces to 6 while its siblings use 2, so the claim was true of the direction
and not of the result.

729 tests green.

timothyandClaude Opus 5 3f0af38509 fix(778): pin the nomatch sentinel — it shipped unpinned, exactly like the guard before it
Local review of the previous commit returned BLOCKED. Both findings taken; nothing
pushed to CI while this was iterating.

MEDIUM — the `nomatch` fix was entirely unpinned. Reverting both sites to `bp_code=404`
left the suite 33/33 green, because no fixture ever emitted an HTTP 404 on the LIST
read: the codes exercised were 000, 403, 500 and 200, and the old `NOT-FOUND` mode had
been repurposed to return 200 with `[]`. So the defect that commit describes could be
reintroduced silently — in a PR whose subject is unfalsifiable guards, one round after
being blocked for precisely that shape. There is now a `LIST-404` fixture and a test;
reverting the sentinel reddens two tests.

The same class, one arm over and found while fixing it: a 200 whose `branch_name` is a
number makes the classifier throw (`//` fires only on null/false), and that was mapped
to `bp_code=000`, reporting "HTTP '000' — Gitea unreachable" about a read that plainly
succeeded. It gets its own `unreadable-rules` sentinel and message, with a fixture and
a test — reverting it reddens.

The pattern across both: a sentinel that doubles as an HTTP code makes a decision state
a cause that did not happen. The decision was safe each time; only the reason lied.

MEDIUM — four comments still described 404-as-a-finding as live, contradicting the hook
comment added in the same commit. The worst said a 404 means "this branch is entirely
unprotected" in a test whose fixture now returns 200 with `[]`, which would have talked
the next reader into re-adding the deny. Renamed that mode `EMPTY-LIST` so it says what
it is.

Also: the hook quoted a reason string it no longer emits; a stray over-indented line
survived the de-indent; `bp_called` was write-only after its reader was removed.

727 tests green.
