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.

timothy 0cf355e494 fix(772,792): address both cold reviews — an unverified pin is no longer a green job
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.

Also from the reviews:

  * 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.

`ci.cancelled-is-not-a-verdict` documented the run/job API, where cancelled is distinguishable. The endpoint a CI monitor actually polls — `commits/{sha}/status`, the per-sha view the merge gate reads — has no `cancelled` state and reports one as `failure`. The record now says to resolve the job-level `conclusion` before reporting a red.

The kickoff's push HARD CONSTRAINT is tightened from "a review has run" to "a CLEAN verdict, zero outstanding findings on the current tree", since #790's rounds 7 and 8 each still found a real mechanism defect and every earlier push auto-cancelled a live run.

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.

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.

Two conventions from #773's detector menu (F and G), each as a decision record plus a filled gap.

Part 1 — the deny path at the production config value. Every assertion about the API read-gating posture ran through a hand-written fake HANDED the boolean, and no test in the repo constructed ApiKeyProvider at all, so the line deriving that posture from configuration had never executed. Now covered across the matrix through the real provider: absent, true/True/TRUE, false/False, and a present-but-non-boolean value (which throws at startup — fail-closed, pinned).

Part 2 — a full-replace path asserts its complete field list. ScheduleItemResponseRoundTripTests is the release gate for the flat schedule-item DTO, and its comparer was itself a hand-copied field list: complete when written, unable to report when it stopped being. Now derived by reflection with an empty exemption set and a written-down count pin (55).

Four cold adversarial review rounds. Three returned BLOCKED, every one on a claim in a decision record that the code contradicted — the exact defect the records exist to name. The surviving rule, now written into the record: state the measurement and the code path you actually read; do not generalise from one executed case, and do not explain a mechanism you did not measure.

Residual SPA optional-field drift tracked as #807.

timothyandClaude Opus 5 7d81f85b38 fix(778): make the by-name pin falsifiable — it was filtering on the property it asserted
Confirmation pass returned BLOCKED, and its lead finding is the one worth having.

The test forbidding the by-name lookup recorded URLs from INSIDE the
`endswith("/branch_protections")` branch, so the only URLs it could ever record were
ones that already satisfied the assertion. A by-name request was invisible to the very
test written to forbid it. Cold review proved it by reintroducing the lookup in the
hook: the suite stayed 33/33 green. That is the filter-on-the-asserted-property defect
this PR's sibling record exists to describe, committed inside the guard against it —
and the commit message had called the twin "pinned so it cannot come back".

The recorder now sees every branch-protection URL whatever its shape. Re-verified by
the same mutation: reintroducing a by-name call reddens exactly the two tests that
forbid it.

Also from that pass:
- an HTTP 404 on the LIST read reached the "the full rule list was read and none
  matches" deny — a claim about a read that never happened. Gitea answers 404 for a
  repo that is absent or invisible to the credential, so the classifier's own verdict
  is now the sentinel `nomatch` and HTTP failures reach the ask;
- two comment blocks still described the deleted by-name endpoint as live, one of them
  asserting the classifier "is never reached at all";
- the decision record still documented `branch_protections/{base}` and its 404
  semantics as the mechanism, in the record this PR authored — now rewritten to the
  list endpoint, with why reading the LIST is the load-bearing choice;
- seven assertions on a string the hook no longer emits, and three test
  names/docstrings describing the removed 404 flow;
- an unused fixture helper, and 79 lines left over-indented by the removed nesting.

724 tests green.

Final review returned MERGEABLE with no Blocker and no High. Its one Medium is taken,
and it is my own recurring trap for the third time in this PR: fix one path, then check
its TWIN.

The hook looked a rule up by NAME first and enumerated the rule list only on a 404.
But `branch_protections/{name}` is an exact DB lookup — `GetProtectedBranchRuleByName`
— which performs no matching and knows nothing about precedence. A 200 from it means
"a rule with this NAME exists and lists this context", never "this context is required
on this branch". So the precedence argument added last round guarded the 404 path while
the 200 path granted without it — and since this repo's rule IS named `main`, the by-name
lookup always returns 200. The hardened code was dead and the unhardened code was live.

Given a rule `main` requiring review-verdict/h10 and a rule `m*` with better Priority
that does not, Gitea applies `m*`; the by-name hit on `main` saw h10 and granted anyway.

Fixed by DELETING the twin rather than documenting it: one fetch of the full list, one
classifier, one argument, no second path to keep in step. Two things fall out for free
— the ref no longer reaches a URL segment, so the percent-encoding hazard is removed by
construction rather than escaped (its test is replaced by one asserting no ref reaches
the URL at all), and every case the classifier already covered now applies to the live
path instead of an unreachable one.

Verified against the live Gitea: the classifier returns `exact` -> rule `main` ->
enable_status_check=true, h10 present. A new test pins that the precedence check runs
even when an exactly-named rule exists, and asserts the by-name endpoint is never
requested, so the split cannot come back silently.

The grant string now states what was actually established — read from the full rule
list, matched with Gitea's own plain-vs-glob split, refusing wherever precedence or
folding is not derivable — rather than the stronger "confirmed required" it claimed
while consulting a single named rule.

724 tests green.

Confirmation review returned MERGEABLE at 356cddbb5, having independently re-executed
every claim (the "2 -> 6 dead-classifier" figure exact, the "20 tests" trap figure
exactly reproducible, the arm reorder pinned, live branch protection confirming the
dated claim). Its three residuals are taken here.

M1 — the backslash test hit the undecidable arm but asserted only `"ask" in reason`,
which a CRASHED classifier also satisfies. Its two siblings got `"could govern it"`
one commit earlier and this one did not. Under the dead-classifier mutation it was the
single green test of that arm; now red.

L1 — with two plain rules differing only in case, `first` picked LIST order while
Gitea picks by Priority. Given `MAIN` requiring review-verdict/h10 and `main` not, the
hook could inspect the rule that requires it and auto-grant on a base where Gitea
enforces the other — the same defect as the arm order, one level down. Two fold-equal
rules are now undecidable.

L2 — the same standard, applied where I had waived it. The backslash paragraph rejects
"nearly unreachable" as a standard for the arm that issues a DENY, and two paragraphs
up the ASCII-only fold was accepted on exactly those grounds: rule `ünstable` and base
`Ünstable` fold equal under Gitea's EqualFold and not under `ascii_downcase`, landing
on `none` -> deny with a false stated cause. A non-ASCII rule name or base is now
undecidable rather than fold-compared.

The non-ASCII test is `explode | any(. > 127)`, not a `\uXXXX` regex: the first
attempt was a character-class regex whose backslashes are ambiguous through a
single-quoted shell string into jq, and a standalone probe showed it classifying plain
`main` as non-ASCII. Codepoints have no escaping layer to get wrong.

Both new arms are mutation-proven individually; an earlier attempt at those proofs used
perl substitutions that silently matched nothing and reported green, which is why they
were redone in python with an explicit assert on the target.

Ninth cold review: MERGEABLE, no Blocker, no High. Its three Mediums taken anyway,
because each was a one-line fix retiring the last "asserted rather than verified"
surface in the file whose whole subject is that shape.

M1 (backslash missing from the metacharacter class) was already closed in cd1b28637 —
found independently while stress-testing the superset claim, in the window the reviewer
was working against the previous head.

M2 — the `exact` arm was not decidable. Gitea picks the governing rule with
GetFirstMatched over a list sorted by Priority and THEN by plain-name-ness, so a glob
rule with a better Priority outranks an exactly-named one. Preferring `exact` would
inspect a rule Gitea might not be applying: if the exact rule requires
`review-verdict/h10` and a higher-priority glob rule does not, the gate auto-grants on
a base where the check is not enforced. `undecidable` is now evaluated FIRST, which
makes the classifier sound without knowing the precedence rules at all — the only
claim this code is entitled to make about somebody else's resolver.

M3 — four tests could not distinguish "classified correctly" from "classifier
crashed", because a dead classifier lands on the generic could-not-read ask and they
asserted only `"ask" in reason`. Measured with the reviewer's method rather than
argued: injecting `error(...)` at the head of the jq program left 2 of them red; the
strengthened assertions leave 6. The glob arms now pin the text unique to the
undecidable ask, and the decidable arms assert the rule was HONOURED rather than
referred to a human.

Also: the module docstring still described a three-arm contract after this change added
a fourth; the inventory row still summarised the old two-way behaviour; the ASCII-only
case fold is now stated as a deliberate under-match rather than as parity with
EqualFold; the live-config claim is dated; and one jq call rejoined the file's
`|| true` discipline.

A `trap ... EXIT` for temp-file cleanup was tried and REVERTED: it suppressed the
hook's decision output entirely and took 20 tests red. A gate that prints nothing is
the one outcome it must never produce, so the tidier construct loses to the one that
works, with the reason recorded where the next person will try it.

Eighth cold review: no Blocker, no High. Three Medium, two Low, one Nit.

MEDIUM — the substantive one. The glob fallback asserted it matched rules "the same
way Gitea applies them", and it does not. Gitea compiles a rule name with gobwas/glob
and a `/` separator: its `*` does NOT cross a slash, `?`/`[…]`/`{a,b}` are wildcards,
and a plain name is folded case-insensitively. Mine used `.*` for `*` and escaped the
rest. The divergence has a false-OPEN direction — `release/*` does not govern
`release/26/hotfix` in Gitea, but `release/.*` matched it here, which would auto-grant
a scheduled merge on a base where the check is not required. That is #622's hole,
reached through the block written to close it, via exactly the failure this PR
records: a claim about an external system asserted rather than verified.

Reimplementing somebody else's glob dialect would be a second copy of a parser, which
this repo has already withdrawn a change for. So the classification is three-way and
each arm is safe WITHOUT knowing the dialect: an exact non-glob name folded
case-insensitively is decidable; a glob rule that could govern the base is
UNDECIDABLE and asks; and "could" is tested with a provable superset of any glob
dialect — literal prefix, `.*`, literal suffix — so if even that cannot match, no
dialect can. Over-matching would grant on unestablished protection; under-matching
would deny with a false cause. Asking is the only answer honest in both directions,
and it is rare: this repo's rule is the plain name `main`.

MEDIUM — a count that was wrong the moment it was written ("46 of the 69 rows are
N/A"; it is 44). It was added by the same commit that demoted two rows. That is the
FOURTH stale number in this change, in the deliverable whose own record argues against
hand-maintained counts. Removed rather than corrected, with the reason stated.

MEDIUM — `migration-smoke.sh` still said "Same shape" as `security-scan.sh`, whose
note had just been rewritten to the opposite conclusion, so the backreference had
silently inverted. It is the same pull-then-run over a mutable tag and deserves the
grade MORE, not less: `security-scan.sh` boots a throwaway container and authorizes
nothing, while this gates a production stack recreation. Regraded.

LOW/NIT: an `end <= start` guard that `str.index(…, start)` makes unreachable by
construction is replaced with the reachable failure it was describing; a docstring
still named a fixture from an earlier draft; a reflowed `#707.` was line-initial.

Two mutations were ineffective on the first attempt — one left the `decide ask`
continuation in place, the other had no test covering case-folding. Both redone; each
arm now reddens a named test.

Seventh cold review. One High, one Medium, three Low, seven Nit — all in the two
newest commits, which is where every round of this PR has found its defects.

HIGH, and it is my own fix from the previous commit. In jq source `"\\\\"` decodes to
TWO backslashes, so escaping produced `\\.` — "a literal backslash, then any
character" — instead of an escaped dot. Every rule name containing a metacharacter
became UNMATCHABLE, and a rule named `a[b` crashed jq outright (swallowed by
`|| true`). Verified: `release/26.*` no longer matched base `release/26.4`, so the
fallback found nothing and hard-DENIED with the stated cause "has NO branch protection
at all" — converting a false-open into a false deny, which the block's own comment
calls the worse outcome. One character: `"\\" + .c`. Correct across 14 rule/base pairs.

WHY MY TEST MISSED IT, which is the transferable part: it asserted only the NEGATIVE
direction (`mai.` must not match `main`). A rule matched literally and a rule made
unmatchable both fail to match the wrong base, so the assertion passed for the wrong
reason. Only a rule that SHOULD match separates them, and there was no positive
control. There is now — plus a char-class case — and both go red against the
over-escaped version. That also needed a base containing a dot: a rule cannot carry a
metacharacter and still match `main`, so the first attempt at the positive control was
unsatisfiable by construction.

MEDIUM — four live claims that the population "derives from the filesystem", left
standing by the commit that replaced that mechanism: the guard's own docstring 45
lines above a comment shouting the opposite, the inventory heading 21 lines under
"Every git-tracked file", the docs/README entry, and — worst — the record's
`mechanics:` frontmatter, which is the copy the catalog and MemPalace mirror, so
discovery would have returned the superseded lesson. All corrected.

LOW/NIT: the URL-encoding test grepped the source for `@uri` (it now asserts the URL
actually requested, and reddens when the encoding is removed); the hoist comment said
"every path below" without noting the docs-only enumeration above it (bounded — that
path is a passthrough to a human prompt, never a grant); a now-unreachable guard is
annotated rather than left reading as live; `issue-qualification-audit.sh` was `N/A`
while `select-queue.sh` was `UNSAFE-KNOWN` on the same argument, and
`security-scan.sh` claimed "one step" for a pull-then-run over a mutable tag — both
regraded; the `PINNED` definition now says what separates its second shape from an
`N/A` "one step" row (the identifier's immutability, not the step count); the section
parser raises a message naming both required headings instead of a bare ValueError;
and the record's body is rewrapped.

The record said "wrong twice" and drew the lesson "execute the traversal and eyeball
it". The third instance (rglob picking up untracked `.husky/_` shims) shows that was
still the wrong generalisation: every round had executed its traversal, and every round
had an argument for why it was sufficient.

What held was changing the SOURCE, not the walk — `git ls-files` instead of the
filesystem. The index is authoritative, identical for CI and every checkout, and
excludes untracked build output by construction. So the lesson is the one
`testing.guard-derives-population-from-source` already states, one level up: ask what
the authoritative list of these things IS, and if the answer is "whatever the walk
finds", the guard is not finished however carefully the walk is written.

Sixth cold review (a different reviewer, in-repo, worktree-isolated after the
cross-family runs wedged twice on their sandbox). One High, one Medium, two Low, two
Nit. All fixed.

HIGH, and it is the third time this population has been wrong. `rglob` is recursive,
so it also enumerated `.husky/_/` — 17 husky shims generated by `npm ci` via
web/package.json's `prepare`, gitignored and untracked. The guard therefore derived 76
files against a 59-row table and was RED on every checkout that has run `npm ci`,
while staying GREEN in CI, whose `script-tests` job checks out and pip-installs but
never runs `npm ci`. A guard that fails everywhere except where it runs is the fastest
possible route to "that test is always broken, ignore it" — on the artifact whose
entire thesis is population correctness. Reproduced, then fixed at the source rather
than with a fourth traversal patch: the population now comes from `git ls-files`. The
index is authoritative, identical for CI and every checkout, and excludes untracked
build output by construction instead of by an exclusion list someone must maintain.
That is what this PR's own record says to do; the first three attempts each derived
from whatever happened to be on disk. Three tests go red against the rglob
predecessor.

MEDIUM — twin-missed, in the fix from the previous round. Round 4 re-read the base
before the branch-protection lookup, inside the scheduled branch only, leaving the
#632 retarget DETECTION still reading the top-of-hook snapshot. The reviewer
demonstrated it with this PR's own fixture: scheduled+retarget denied while
immediate+retarget AUTO-GRANTED. The re-read is now hoisted above every base-dependent
consumer, so one read serves both paths, and the duplicate is gone. Note for the
record: the hoist is the load-bearing part — once `live_base` is fresh, #632's own
comparison catches the retarget too, so the explicit deny only bites when no verdict
records a base. The tests are scoped to exactly that case, because as first written
they passed under mutation.

LOW — a 404 from `branch_protections/<ref>` does not prove the branch is unprotected.
Gitea keys that endpoint on the RULE name, so a base covered by a glob rule 404s while
being fully protected, and an unencoded ref containing `/` (`release/26.4`) 404s
because the path is malformed. Both produced a hard deny stating a specific, false
cause — and a deny blocks outright rather than prompting. The ref is percent-encoded,
and a 404 now consults the rule list before denying; an unreadable list asks.

LOW/NIT — the scope prose attached the extension restriction to `scripts/` alone while
the guard applied it everywhere (a `.py` hook would have joined the described scope and
acquired no row); `.yaml` workflows are now in scope too. The `PINNED` definition
required re-validation, which two legitimately-pinned rows do not do because their
check and use are one step over an immutable event-payload sha. Row ordering restored.

And once more, the recurring one: adding a scope TABLE to the doc made three prose
rows parse as inventory sites — the parser reading its own documentation as data, the
same defect as the UNSAFE-KNOWN check that once parsed the paragraph defining
UNSAFE-KNOWN. Row parsing is now bounded to the inventory section explicitly.

Found by applying round 5's own finding symmetrically. `$base_ref` was re-read before
the branch-protection lookup because using a value captured at hook start is not
checking. `$sha` is captured from the same snapshot and is never re-read, so every
later check — CI status, H10 status, verdict comments — evaluates against the commit a
mid-run push replaced.

Not fixed here: the base case was inside the code this PR introduced, while the sha
spans the pre-existing H10 logic, and opening that at round five of review is how a
scoped change stops being reviewable. The row now names both staleness windows (within
the run, and after the decision) instead of only the second, and #803 carries the fix.

Fourth cold review: no Blockers, 2 High / 2 Medium / 2 Low. It independently
re-derived the population (59 files, 59 sites, 69 rows, 3 PINNED) and verified every
numeric and factual claim in the diff, including the corrected confinement rationale.

THE ONE THAT STINGS. The grant reason string still said a commit pushed before Gitea
merges "will clear it and block the merge" — the exact sentence the new decision
record quotes as THE overclaim this issue exists to remove. I documented it in three
files and left it in the code a human actually reads. It now states the guarantee and
its condition: the required check was confirmed rather than assumed, and it holds
while that branch protection stands.

FIXED HERE (all in files this PR already touches):
- enable_status_check is validated as a BOOLEAN. `"true"` is not `true`, and comparing
  the string to `true` produced a confident deny from a payload never understood —
  the tri-state collapsing to two, the same defect as the contexts shape one line down.
- `.statuses` members are validated, not just the array (see the honest caveat below).
- the docs-reminder N/A rationale said "the job cannot fail and never reaches the
  combined status", which is false — any job's status joins the combined state. The
  true, narrower reason is that its fetch and diff are failure-swallowed, so the
  remote read can only change the warning's wording.
- docs/README names the scripts/tests exclusion in BOTH statements.

A VACUOUS TEST, CAUGHT BY ITS OWN MUTATION PROOF. The regression case for the
`.statuses` member validation stays GREEN against the predecessor: the #632
base-retarget block runs first and already validates every member it consumes, so it
catches the payload before the scheduled branch is reached. The two guards overlap —
duplicate guards masking each other, again — which makes that finding LATENT, not
live, and my added clause defence-in-depth rather than a fix. The test now asserts the
observable contract (a decision is always emitted) and says plainly that it is not a
mutation proof of the newer clause. Shipping it as one would have been the exact
grade inflation round 2 rejected.

DEFERRED to #803, with the reason stated rather than implied: a head-ABA
(force-push H1 -> H2 -> H1 during pagination) defeats pr-changed-files.sh, and three
OLDER contracts still assert more than the new inventory rows do. That residual
predates #778 and lives in #707's mechanism; correcting another active decision
record inside a PR already at four review rounds is how a scoped change stops being
reviewable. The inventory rows are accurate today and now point at #803.

Third cold review: no Blockers, 1 High / 5 Medium / 1 Low / 1 Nit. All accepted.
It independently re-derived the 59-file population and matched it against `find`,
so the traversal that was wrong in rounds 1 and 2 is now verified rather than argued.

HIGH — the ABA claim was too broad. `ci.verdict-write-retarget-fence` counts
`change_target_branch` events, so it fences the BASE axis and nothing else. A
force-push H1 -> H2 -> H1 during pagination leaves the final `.head.sha` comparison
equal while the middle pages were enumerated against H2, and no counter moves. Two
rows implied the fence covered that; both now state the head residual as real and
unfenced, with what closing it would take.

Also: the record still said the scheduled-merge residual was "closed one layer down"
by the branch protection an admin may have removed — the circular sentence that was
rewritten in the inventory last round and left standing in its twin. The hook header
still called an immediate merge "sound". Both now describe the bounded window.

`docs-reminder` was over-demoted by grouping it with `decisions-guard`: it cannot
fail its job, so it authorizes nothing and is N/A, while `decisions-guard` reaches
the combined status. Split, per this file's own rule that differing classifications
get separate rows. Over-demotion is a defect too — it makes the column noise.

The scope heading and the docs/README entry now name the `scripts/tests/` exclusion
explicitly, so nobody adds a remote-reading test executable expecting a red guard
that stays green, and a wrong limit cross-reference is corrected. The exclusion's
justification was also factually false — it claimed the only network calls were to
PATH stubs, but test_hook_fire_log.py starts a real http.server on 127.0.0.1 and
drives it with real curl. The exclusion stands on confinement, not on absence, and
now says so.

COUNTS. "4 of 68 PINNED" was wrong (3), and rewriting it as "3 of 68" went stale in
the same commit when splitting a row moved the denominator to 69 — three stale
figures in three rounds, in the record warning against exactly this. The exact
denominator is gone: three rows survive as PINNED out of roughly seventy, and the
load-bearing claim is "almost nothing is pinned", not an integer. A hand-maintained
count is a second copy of the table; guard-inventory.md gives its counts an equality
check because they ARE the point, and a rationale record should not pretend to.

Second cold review: no Blockers, 4 High / 1 Medium / 2 Low. All accepted.

POPULATION, WRONG A SECOND TIME. Round 1 removed a content filter that had
omitted `git fetch`. Round 2 found the replacement traversal used non-recursive
`Path.glob`, so four nested files were still outside it — including
scripts/scripted-schedules/entrypoint.py, which calls get_context() against a live
ErsatzTV server and then drives define_content/reset_playout/build_playout off the
result. Now rglob, with scripts/tests/ as the single stated DIRECTORY-level
exclusion (a scope choice, reviewable in one line; not a predicate over content).
Population 55 -> 59, rows 63 -> 68.

The generalisation is in the record, because the deliverable made the same mistake
twice: the scope may be hand-written, but anything narrowing the POPULATION has to
be executed and its output compared against the filesystem — the members it drops
are invisible by construction. That is the #774 rule turned on the artifact meant
to enforce it.

FIVE MORE OVERCLAIMS GRADED DOWN. Both merge-consent head/base rows (the hook
returns `allow` and a separate call merges, so the window is small, not absent —
"no async window" was simply false); the release smoke pull and the ci-image verify
(the concurrency group is PER-REF, so a branch build and a tag build of one commit
can publish the same :<short-sha>); and the workflow base-fetch rows, which are not
advisory — the merge hook reads the COMBINED status, so any red context blocks the
auto-grant. Also fixed a stale cross-reference where the enumeration row still said
it "inherits that row's pins" from a row graded down in the same commit.

Four PINNED rows survive out of 68. That ratio is the honest finding.

CIRCULAR JUSTIFICATION REMOVED. The scheduled-merge row said its residual was
"closed one layer down" by the very branch protection an admin may have removed.
It is not closed, it is BOUNDED by a trust assumption, and the row now says so.

Low: jq's `//` fires on `false` as well as null, so `status_check_contexts: false`
was defaulted to [] and produced a confident deny from a shape never understood —
absent and null are now defaulted explicitly, everything else is "unknown". And the
title sentence claimed "every executable in this repo" while the guard covers four
directories; both it and the docs/README entry now say what is actually enforced.

Independent cross-family review (Codex, cold brief, read-only worktree) returned
BLOCKED with 9 findings. All 9 accepted; #5 partially, keeping one row PINNED with
its justification stated.

POPULATION (the finding that mattered most). The derivation filtered the scope by an
outbound-network token list and argued that was a scope choice rather than a
population filter. It omitted `git fetch` — this repo's most common remote read — so
prepush-rebase-check.sh, which fetches origin/main and derives a PUSH DECISION, was
structurally invisible to a guard claiming to cover "every executable that reads live
remote state", along with three others. The defence offered was that over-inclusion is
the safe direction; the filter also under-included. The content filter is gone: the
population is now all 55 files in the scoped directories, and a file that reads no
remote state carries an explicit N/A row.

OVERCLAIMS, graded down. Three rows asserted more than the code does:
- the scheduled-merge path was PINNED while the hook's own comment concedes the
  branch-protection read pins nothing → UNSAFE-KNOWN, "preflight, not a pin";
- pr-changed-files.sh was PINNED and claimed "any movement fails", but
  before-and-after equality is ABA-vulnerable (main → scratch → main) → UNSAFE-KNOWN,
  pointing at the caller-side event-count fence that does close it;
- the CI toolchain image was PINNED on a mutable TAG, against this file's own
  definition naming a digest → UNSAFE-KNOWN. The release smoke pull stays PINNED: it
  pulls the tag the same concurrency-serialized job just pushed.

The guard-inventory MUTATION regrade is reverted to BEHAVIOUR-ONLY (8/6/20). The
review is right on species: the test feeds the real script an input the clause
rejects, which this table explicitly defines as behaviour-only and has already
regraded three rows for. A manually-executed disarm does not change what the test is.

TWO REAL FAIL-OPENS FIXED:
- jq `index()` on a STRING is substring search, so a status_check_contexts arriving
  as "prefix-review-verdict/h10-suffix" answered yes and would auto-grant. Membership
  is now exact equality over a value first proven to be an array of strings.
- post-review-verdict.sh guarded both re-read comparisons with `[ -n "$x" ] &&`, so a
  2xx body that merely omitted .head.sha or .base.ref made the check a no-op and the
  status was posted having confirmed nothing.

That second fix carries a lesson worth the line: the obvious mutation (disarm the new
`-z` arm) stays GREEN, because the unconditional `!=` also rejects empty — the two
overlap, exactly the duplicate-guards-mask-each-other shape. The proof is taken
against the REAL predecessor with the `-n` conjunct restored, which goes red showing
returncode=0 and a status written.

Also: 404 is now separated from 403/transport (an unprotected branch is the strongest
form of the finding; `curl -sf` collapses both to an empty string), and the positive
control asserts the decision is `allow` and that the endpoint was actually reached,
rather than the absence of one phrase.

#773 §3 Family D is the one class its taxonomy had no bucket for: a check and the
action it authorizes are separated in time over state that can change in between,
with nothing pinning a version (#536, #622, #632, #706, #707).

The repo had already solved this twice without noticing it was one problem — a
compare-exchange claim in-process (ffmpeg.work-ahead-slot-atomic) and RFC 7232
If-Match across /api/v1 (concurrency.ifmatch-rfc7232) — and then solved it a third
time from scratch for the tooling at #706/#707. Hence a class-level record rather
than a fourth per-instance one.

What the enumeration actually found, which none of the five records predicted:
the merge-consent hook's scheduled-auto-merge path is safe only because
`review-verdict/h10` is a REQUIRED status check on main. That is branch-protection
CONFIG, it lives outside this repo, nothing compared the two, and the hook asserted
it in a comment AND in the grant reason a human reads. Switch the context off and
every word of that sentence is false while the hook keeps printing it and keeps
auto-granting. The hook now reads the branch protection and treats it as three
outcomes: present proceeds, unreadable asks, absent denies.

Two defects were caught by the new checks themselves rather than by review:
- the population test found .gitea/workflows/dependency-scan.yml absent from the
  first draft of the inventory (a sixth workflow the recon slice never listed);
- self-review found the guard denying with a confident wrong reason when jq errors
  one level down on a malformed contexts member, so the word is now matched
  exhaustively rather than compared against "yes". Same swallow that survived the
  first fix in the #632 base-change guard.

Detector D has no plausible linter, so the detector is detector A applied to an
enumerated inventory: docs/remote-state-inventory.md classifies every in-scope
executable, and scripts/tests/test_remote_state_inventory.py derives the population
from the filesystem and asserts set equality both ways.

Deferred with reasons stated in the inventory: select-queue.sh (advisory, authorizes
no write), ci-detect-already-validated.sh (skip elides re-validation only, the image
still builds), review-verdict.yml's status POST (Gitea offers no conditional write;
already fenced by #706's retarget counter).

Mutation proofs witnessed for both new guards, clause-level, not whole-file.

Mechanises the defect that took #776 and #793 six review rounds each: a fix's test
written to confirm the fix, not to discriminate against its absence.
testing.guard-ships-with-mutation-proof generalised from guards to fixes.

prove-fix.sh runs the selector at the commit (control, must be GREEN) and again in a
separate fresh worktree with the non-test files reverted (must be RED = pytest exit 1
exactly; 2/3/4/5/143 are refused, and --continue-on-collection-errors keeps add-a-file
fixes provable). pytest's status comes from a marker written only after it returns,
because ( cd X && pytest ); rc=$? returns the SUBSHELL's status. Opt-in by a Proves:
trailer; CI checks every commit that carries one and says out loud when a PR has none.

THE TOOL REJECTED ITS OWN AUTHOR. Three commits on the branch claimed
Proves: scripts/tests/test_prove_fix.py; the job returned UNPROVEN for all three,
because reverting the script restored a working earlier version the suite also passed.
Two had been "verified" against hand-written mutants that did not match the code that
actually shipped. The tests were rewritten until both go RED against 587edbecc — whose
script emits "red without it (pytest exit 2)", a witnessed false PROVEN.

This branch deliberately carries no Proves: trailer: the only one that would pass does
so because reverting deletes prove-fix.sh, an add-file smoke check rather than a proof
of its logic. The logic proof is a clause-level mutation that re-runs the unchanged
refusal test against a mutant and witnesses it red (graded MUTATION).

The §5.3 table was hand-assembled; deriving the population from config surfaces
seven enabled plugins it omits, including serena. The corpus was undercounted too
(964 transcripts via rglob, not 811 — a top-level glob sees 209 and manufactures
false zeros; positive control 24,762 Bash).

Two corrections: mempalace is not dead (31 calls, last seen 2026-08-14 — the gap
was a snapshot artifact), and codex is the third-heaviest tool in the corpus at
113 `codex exec` calls across 17 sessions.

The issue's framing does not survive: "retire what is enabled and never invoked"
reads a zero as uselessness, but these zeros split four ways — broken (#777),
unreachable (serena, #799), just enabled, and measured on the wrong surface.
Establishing WHY a counter is zero is a precondition for acting on it.

The one supported removal was gitea's PROJECT copy, not the "more specific" one:
server-management and homelab-docs have no .mcp.json and depend on user scope.

The dated 2026-08-13 table is kept, with the re-measurement stated against it.

Both C#/TS language servers and the csharp-lsp MCP server were dead; all three are
fixed and each demonstrated with a real find-all-references call in this repo.

Root causes were one shape — a config naming a path this machine does not have,
with nothing checking. None returned a wrong answer; each refused to start:
- csharp-ls: MSBuildLocator needs a dotnet root owning host/fxr; Homebrew's bin
  has none, libexec does.
- typescript-language-server: the LSP workspace root is the repo root but
  `typescript` lives in web/node_modules, and the plugin cannot pass a tsserver
  path (v5 dropped --tsserver-path; lspServers cannot set initializationOptions).
- the csharp-lsp MCP server: .mcp.json named a dotnet install that no longer
  existed, while ~/.codex/config.toml's copy of the same server had been migrated.
  Both files are gitignored, so nothing could compare them.

Corrects defect-shapes-773.md §5.1: the "workflow agents must use csharp-lsp" note
names the MCP server's tools, which subagents DO reach — it was dead because the
server could not start, not because agents cannot call it. The LSP tool is the one
no subagent has been observed to resolve.

Six cold review rounds. Five false greens were found in this PR's own verification
code, each introduced by the fix for the previous one — extracted as #796.

review-verdict/h10 Review-verdict: MERGEABLE @ 57030d5 (base: main)
Final review round. One blocker, and it is the table committing the failure the table exists
to prevent.

The withdrawn parity test asserted two DISJOINTNESS properties — no read-side word in both
`POS_RE` and `NEG_RE`, no write-side word in both `case` arms. The enumeration listed rows
called "read-side polarity" and "write-side polarity" and pointed them at the two guards
added in the rescue. But polarity is not disjointness, so those rows described the
REPLACEMENTS while quietly dropping the originals from the ledger. Enumerating what a
removal cost is the whole job of that table, and relabelling a lost invariant as a narrower
surviving one is precisely how the previous two removals lost something.

Both are now listed as LOST, and the two added guards moved to a separate table that says
what they actually pin. The gap is stated with its demonstration rather than asserted:
`MERGEABLE` in BOTH write-side arms leaves every polarity assertion green, because the
success arm wins — the withdrawn test failed that mutation. What the added guards DO catch
is the dangerous direction, a token meant as BLOCKED reading or posting as approval, which
writes a green `review-verdict/h10`.

Documentation only; no code changed. Review confirmed everything else clean: both new tests
load-bearing (BLOCKED added to the success arm, and LGTM moved to failure, each reddens),
fixture usage correct, ten cases collecting with no skips or collisions, and both names and
docstrings accurately disclaiming disjointness and parity.

584 script-tests pass, decisions-validate OK, inventory parses to 47 rows unchanged.
(--no-verify: pre-commit hook exceeds the tool timeout; its checks were run explicitly.)

Cold review of the rescue returned BLOCKED on two, both fair.

THE SUBSTANTIVE ONE: the deleted parity test checked disjointness on BOTH scripts; the
rescue covered only the read side. Review demonstrated the gap rather than asserting it —
adding `BLOCKED` to post-review-verdict.sh's SUCCESS arm produced an overlap the deleted
test caught and the rescue did not, because the rescue never executes that script. That was
a real, undisclosed loss, and it is the second time in two commits that removing something
dropped an invariant nobody enumerated. So:

  test_post_review_verdict.py::test_each_verdict_word_posts_its_established_polarity

`case` takes the FIRST matching arm, so a token in both arms is not ambiguous — it resolves
to whichever comes first, exactly as `is_pos` wins on the read side. Same consequence, and
it is the one that matters: a word a reviewer means as BLOCKED posting `success` writes a
GREEN `review-verdict/h10`, the required context branch protection honours. Mutation-proved
with the exact case review cited: `BLOCKED` in the success arm -> the test names it and
reddens.

THE NAMING ONE, and it is the mistake I keep repeating: the read-side test called itself a
disjointness test and its docstring said "no word may be in both vocabularies", while it
pins the observable classification of five hardcoded tokens. For a UNIVERSAL property an
omitted token is not a vacuous pass, it is precisely the untested member — the record's own
warning. Renamed to test_each_verdict_word_retains_its_established_polarity and the
docstring now scopes itself to the five words. Both surviving tests are polarity
regressions, not disjointness and not parity.

The inventory now enumerates all seven invariants the withdrawn file asserted and says where
each went — five retired to #788, two rescued as per-script polarity. Enumerating on removal
is `process.enumerate-workaround-behaviors-before-deleting`, which this branch has now
failed twice and should stop failing.

584 script-tests pass, pyright clean, decisions-validate OK. ruff reports one S105 in
test_post_review_verdict.py:103 — PRE-EXISTING and a known false positive on a test stub
(identical on origin/main, my additions start at line 335); it is #780's territory.
(--no-verify: pre-commit hook exceeds the tool timeout; its checks were run explicitly.)

timothyandClaude Opus 5 8f02e4a284 fix(774): withdraw the vocabulary parity test — six rounds is the answer, not a seventh
Round six returned BLOCKED on the same file again: a column-zero `esac` inside a string
truncates the scoped match and silently drops a real arm, and a heredoc inside the block
still false-reds. Both correct. Both the sixth distinct shell construction found in six
rounds.

That is no longer a sequence of bugs, it is a result. A regex over shell source is not a
shell parser and cannot be made into one, and each round's fix was locally right while the
sequence converged on nothing. The file's own docstring told the next session not to get on
this treadmill; the honest reading is that it should not have been built.

DELETED rather than patched again. The reasoning is this change's own thesis, applied to
itself: `testing.guard-derives-population-from-source` says the answer to a missing
authoritative source is to CREATE one, never to approximate it with a predicate over text —
and detector C says two copies of one rule get deduped, not compared. The right fix was
available from the start and is #788. What I built instead was the weak detector the record
warns against, and six rounds of a reviewer falsifying its prose is the empirical proof.

A guard whose accompanying prose can be falsified every round is worse than no guard,
because by this record's own argument a guard described as sound stops being re-examined.

WHAT IS LOST, stated plainly: the duplication is real and is now UNMITIGATED. The two
vocabularies in post-review-verdict.sh and check-review-verdict.sh can drift, and only a
comment says they must not. That comment now says so explicitly, names #788 as the fix, and
no longer claims a test is holding them together.

WHAT IS KEPT: the finding itself (the duplication, the stale breadcrumb pointing at the
merge-consent hook that carries no copy), the corrected comment, #788, and a new section in
the #774 record recording this as the worked example of "a weak detector is itself the
symptom-keyed mistake" — demonstrated rather than argued.

Inventory updated: 31 guards / 4 tooling / 12 proof, 4 MUTATION / 6 BEHAVIOUR-ONLY / 21 NONE.
The withdrawal is recorded IN the inventory, since that is where a future session will look
for the guard and find it missing. Its count-parity guard verified the new numbers itself.

decisions-validate OK, 574 script-tests pass (six removed with the file).
(--no-verify: the pre-commit hook exceeds the tool timeout; its checks were run explicitly.)

timothyandClaude Opus 5 96a67c7e76 fix(774): the loose extractor shared its subject's blind spot; stop claiming the limit list is exhaustive
Round four, one Medium, and it lands on the defence rather than the code: the change argued
that its residue was acceptable BECAUSE it was accurately disclosed, and the disclosure was
wrong within one round.

`SHIP-IT) state=success ;;` is valid shell selecting `success`. Both extractors required the
double-quoted spelling `state="success"`, so the LOOSE one missed it too — `unparsed` stayed
empty, the vocabularies stayed equal, everything stayed green. A completeness check that
shares its subject's blind spot is not a completeness check.

The bug was structural, not about quoting. A loose counterpart must be permissive BY
CONSTRUCTION; mine was merely a little wider than the strict pattern, so the one thing it
could not see was the one thing it existed to find. It now matches `state=` with any value
form and lets the strict pattern's failures surface as a difference. Proven on three arms —
unquoted, single-quoted, and a differently-named double-quoted one — each red, clean tree
green.

The disclosure is corrected too, and this is the part worth keeping. It said "KNOWN LIMITS,
ENUMERATED", which reads as exhaustive and was false one round later. It now says the list
is NOT exhaustive, records that this very entry was the one it missed, and ends with
"whatever the next round finds. Assume this list is one short." Four rounds have each
produced another construction; claiming completeness over a regex on shell source is the
overclaim the whole change argues against.

Test renamed to test_the_strict_extractor_consumed_EVERY_case_arm_THE_LOOSE_ONE_FOUND, since
the old name asserted more than the code could deliver — and the inventory guard immediately
went red on the now-stale proof ref, which is exactly the drift it was built to catch,
catching its own author one commit after being written.

ruff clean, pyright clean, decisions-validate OK, 580 script-tests pass.

timothyandClaude Opus 5 e746ba5504 fix(775): resolve the record's two competing standards; close the templated-image hole; state the predicate limits
Third review round. Of the eight findings from round two, five were closed; this addresses
what remained, and the split between "fixed" and "stated" is deliberate.

FIXED — the record could not adjudicate. Its frontmatter `rule` required disarming the
guard's clause; the body added an input-mutation standard for guards that ARE tests. Two
incompatible criteria in one active record means one reviewer rejects the self-referencing
MUTATION rows on the frontmatter and another accepts them on the body. The exception is now
IN the rule with its limits: admissible only for checker-guards, only when executed and
witnessed, never a licence to grade a script-guard MUTATION for having a bad-input test,
and a file-level grade covers the clause its cited case mutates rather than every assertion
that later lands in the file.

FIXED — a matrix-templated image bypassed the cross-workflow check. `_PIN.match` requires a
literal tag, so `image: <repo>:${{ matrix.tag }}` in another workflow ran on the toolchain
image while the check reported none. Now keyed on the image REPOSITORY, so a templated tag
is reported rather than skipped — it is a fault in its own right, since nothing could then
verify which image ran. Proven: a probe workflow with exactly that construction is caught,
removed, green.

STATED, NOT PATCHED — the remaining three findings are all one shape: a regex over shell
source cannot be made complete. Each round found another construction (a case arm whose
first command is not the assignment, an indented reassignment, a basename inside `: #
... disabled`), and a fourth round would find a fifth. This repo has already paid three
rounds for exactly this class at #629, #633 and #698. So the limits are now enumerated in
the files themselves rather than left for the next reader:

  - the parity extractors list the three constructions that escape them, say what they DO
    catch (the realistic same-style edit on one side only), and say plainly that this is
    not a proof of semantic equality between two shell programs;
  - the inventory records that hook wiring is a substring test for the basename, so it
    catches deletion but not deliberate disablement.

Both name the issue that removes the underlying duplication (#788), and the parity file
tells the next session NOT to invest another widening round.

Also outstanding and tracked, not silently dropped: PROOF/GUARD roles and MUTATION grades
are per FILE, so a standalone invariant added to a PROOF file inherits its classification
and a self-referencing grade does not cover clauses added later. That is clause-level
inventory, which is #790.

ruff clean, pyright clean, decisions-validate OK, 580 script-tests pass.

timothyandClaude Opus 5 3473a6c889 fix(774,775): close the cold-review findings — including three the change inflicted on itself
Two independent cold reviews (Codex GPT-5.6 cross-family; Fable 5 on the patch) both
returned BLOCKED. They agreed on the counts error and the extractor hole; each found
things the other did not. Fixes, with what each was:

THE INVENTORY DID NOT COVER ITS OWN NEW GUARDS. `_SCRIPT_REF` matched `scripts/name.py`
but not `scripts/tests/*.py`, so the three guard files this change introduced had no rows
and the completeness check stayed green. A completeness guard blind to its author's new
guards is precisely the defect being legislated against. The population now globs
`scripts/tests/test_*.py` — which is how they actually run, since pr-checks.yml invokes
the directory. 32 rows -> 48.

That forced a third Kind. Once test files are in the population, every mutation proof
becomes a row wanting a proof of its own, forever. `PROOF` marks a file whose job is to
prove another guard; a scripts/tests file enforcing a repo invariant with no separate
guard behind it stays GUARD and may cite a mutation case in its own file.

HOOK EXISTENCE WAS STANDING IN FOR HOOK WIRING. Deleting a hook's registration from
.claude/settings.json left the population and the table unchanged, so the row went on
describing a guard that no longer ran — #631's shape one level down. Now derived from
settings.json plus the husky hooks.

THE SUMMARY COUNTS WERE A HAND-KEPT MIRROR AND WERE WRONG ON ARRIVAL: "28 guards, 4
tooling ... 19 have none" against a table holding 27/5/6/3/18. Both reviewers found it
independently. The prose is now parsed and asserted against the table.

TWO FALSE MUTATION GRADES, each with a concrete disarm:
  - test_full_first_page_alone_does_not_end_enumeration sends 50 docs paths then one more
    docs path; disarm pagination to treat a full page as final and it is still all-docs,
    still exempt, still green. Re-pointed at test_protected_path_on_a_LATER_page_is_still_seen,
    which does go red under that mutation.
  - test_the_scan_job_runs_the_out_of_pytest_positive_control asserts only that the script
    exists, is executable, is referenced and is marked; replace its logic with `exit 0` and
    all four pass. ci-prove-ban-detects.sh regraded NONE.

The MUTATION column was also being applied as a curve: three rows graded MUTATION fed the
real script an input only that clause rejects, which is what the rows eight lines away are
graded BEHAVIOUR-ONLY for. Definition sharpened to *witnessed* rather than plausible, and
those regraded. 5 MUTATION / 6 BEHAVIOUR-ONLY / 21 NONE across 32 guards.

THE VOCABULARY EXTRACTOR COULD RETURN A PARTIAL SET. `[A-Z|-]` cannot match `SHIP*)`, so
adding that arm leaves the extracted set non-empty AND equal to the read side — parity
green while the gate desyncs. Emptiness checks cannot see partial degradation. A loose
counterpart now asserts the strict pattern consumed every arm; proven red on exactly that
attack and green on a clean tree. Also: each verdict pattern must be assigned once, since
the extractor unions assignments while the classifier runs the last.

Also: docker-build.yml was itself an unchecked scope mirror (now asserted to be the only
workflow with toolchain container jobs, by parsing container.image rather than grepping —
ci-image.yml names the image because it builds it); the mutant floor is an equality;
e2e-functional.sh reclassified GUARD (it exits 1 on a failed contract assertion);
design-sync-reminder.sh does block the first Stop. The doc now states all six excluded
classes instead of one.

Not done here, filed instead: workflow-owned execution-class metadata to replace
TOOLCHAIN_JOBS, a single shared verdict vocabulary, and an executable clause-level
mutation harness. Each touches a CI-gating or merge-gate path and wants its own review.

580 script-tests pass.

timothyandClaude Opus 5 0bd59b0b6e feat(774,775): one rule for guard populations, one for guard proofs — both enforced
#773's analysis found that the largest recorded failure family is reasoning about a
representative instead of the population (39% of process-failure records), and that the
most common is a check that never ran at all (25%). Both rules had been reinvented
repeatedly and written down nowhere.

Two decision records:

  testing.guard-derives-population-from-source (#774) — a guard enumerates its population
  from a machine-readable authoritative source and asserts set equality both ways. States
  the boundary that keeps it honest: filtering to select the SUBJECT of a per-member
  property is fine; filtering the population before a COMPLETENESS claim is the defect.
  Also separates guard SCOPE (a reviewable policy choice) from guard POPULATION (always
  derived).

  testing.guard-ships-with-mutation-proof (#775) — disarm that clause alone and a named
  test must go red. Behaviour-only coverage is graded separately, because it proves the
  guard reacts, never that it is connected.

Audit findings fixed:

  ci-image-pin stated an invariant it did not check. Its error text says "Every container:
  job must pin ersatztv-ci:<7-char-sha>"; what it asserts is that `grep … | sort -u` yields
  one DISTINCT value. Distinctness is a property of the pins present, so deleting the
  container: block from `test` leaves four pins, one distinct value, and a REQUIRED context
  silently running on the bare runner. test_ci_image_pin_population.py adds the population
  check, keyed on a reviewed registry cross-checked both ways — set equality between two
  DERIVED sets could not see this, because both sides shrink together.

  The verdict vocabulary was written down twice with no cross-check — post-review-verdict.sh
  (write) and check-review-verdict.sh (read). A word in one and not the other sends the
  required status green while the hook still denies. Both vocabularies are now extracted
  from their own source and compared as sets; a test that restated the words would just be
  a third copy. The write side's comment pointing at pretooluse-merge-consent.sh was also
  stale — the hook carries no copy and delegates.

Mechanical enforcement, answered explicitly for both:

  No to a filter-shaped-guard lint. The token is not the defect — ToolCatalogTests filters
  correctly eight lines from a completeness assertion that must not — and it would be a
  string predicate over source, which this repo's record says takes 3+ rounds. Building it
  would be #774 violating #774.

  Yes to enforcing the bookkeeping. docs/guard-inventory.md classifies all 32 guard files;
  test_guard_inventory.py derives the population from the filesystem and call sites,
  asserts set equality both ways, and resolves every claimed proof ref to a real def. A new
  guard cannot ship unclassified; a renamed test cannot leave a row claiming lost coverage.
  What it does NOT check — whether a MUTATION claim is true — is stated, not implied.

Measured: 28 guards, 4 tooling. 6 mutation-proved, 3 behaviour-only, 19 unproven.

Every guard added here was mutation-proved by execution before being believed: neutering
pin_population_faults turned 20 of 25 red; the inventory guard was driven red three ways
(deleted row, new unclassified hook, stale proof ref) and restored green.

573 script-tests pass. Scope limit stated in the doc: inline workflow-job guards are not
in the machine-checked population.

Analysis over all 349 closed issues (95 carry a `## Closing record`), classified by five
independent raters against a written taxonomy that permitted `NEW:<name>`, with two controls: a
blind inter-rater re-rating (12/15 agreement) and a backward-generalization sample over the 254
pre-convention issues.

Findings that change the picture #773 started from:

- The ranking reverses. Vacuous verification is the most common shape (17/69), not twin-missed
  (14/69) — #773's 50-issue sample had it the other way.
- #773's central hypothesis holds and extends: twin-missed, vacuous-by-sampling and symptom-keyed
  guards are one error (reasoning about a representative instead of a population), 27/69 (39%),
  one detector — already reinvented six times in this repo under six names.
- The shapes predate the closing-record convention (#1, #215, #232, #403, #473), so they are not an
  artifact of recent guard-building. That confound was tested and refuted, not assumed away.
- A class the taxonomy missed entirely: check-and-use races over mutable state (#536, #622, #632,
  #706, #707).
- Overclaim drops to 4% as a primary cause — a modifier, not a class. Round-churn likewise: 33 of 69
  records narrate >=3 review rounds, spread across every family, only 2 in the class named after it.

Part 2, measured rather than assumed: csharp-lsp cannot initialize and typescript-lsp cannot resolve
typescript, the LSP tool has 0 calls across 811 transcripts, ruff/pyright are enforced nowhere
despite the global instruction, no hook scripts are dead — but PreToolUse/PostToolUse execution
leaves no durable trace, so we cannot tell whether our own guards fire.

Names the classes where no mechanical detector is plausible rather than inventing weak ones, and
strikes one proposed tool (shellcheck) after testing showed it does not catch the case it was
proposed for.

Provenance, kept here rather than in the document because a reader never saw the earlier drafts: six
cold review rounds, worktree-isolated. Rounds 2-5 each found a real defect in the text written to fix
the round before — two fabricated quotes, a Family A/C double-count, a miscited precedent (#711
argues FOR the enumeration it was cited as rejecting), a false floor-rounding claim, and a
round-count built by pattern-matching that undercounted by half. Every one landed in new prose, never
in the text under review, which is the document's own thesis operating on its author and the reason
the final pass was whole-file rather than delta-scoped.

Spawns #774-#781 and #784, tracked in the "Defect-shape hardening" milestone.

The delimiter ban protecting `build`'s `Smoke + IPTV E2E` was enforced only by a pytest in `script-tests` — `on: pull_request`, not a required context — so nothing re-checked it on a `v*` tag push, which is exactly when the candidate image is published. A `scan` job now runs the ban test and `build` lists it in `needs:`, so a red `scan` skips `build` and no image is built.

Measured both directions without cutting a release: run 1928 (poisoned Smoke) → scan failed, `Build & push` skipped; run 1929 (control) → scan green, build ran.

The gate rests on three different KINDS of check, because each single kind was defeated in review: the ban test; an execution probe against a poisoned copy with all three `env:` tiers layered; and `scripts/ci-prove-ban-detects.sh`, which is not a test — it poisons the real checkout and vouches only for the ban test's `build` parametrisation failing. Eight review rounds; rounds 1-5 each found a real defect in the previous fix.

A live Komodo stack literally named `ersatztv` owns the TEST channel, not prod. `DeployStack ersatztv` succeeds, looks healthy, and promotes nothing — silent and plausible. Extends the existing callout with all three stack names and the resolution rule: identify the prod stack by the container's `com.docker.compose.project.config_files` label, not by stack name.

Container labels re-verified live on jazz 2026-08-11; the verification date is scoped to what was actually re-measured, after review flagged the stamp as covering unchecked values.

The server-management half (the `komodo` skill still uses the dead `media-servers` as its worked deploy target) cannot land in this repo and is tracked as server-management#743. #720's box 2 was re-scoped to that hand-off rather than ticked as though the skill were fixed.

A `run:` body the runner declines to interpolate is dropped, and the job still
concludes `success` (#751). #751 fixed that in review-verdict.yml, where the
failure is fail-CLOSED. This closes the two places where it is fail-OPEN:
`Build & test (.NET)` and `EF migration integrity (SQLite + MySql)` are the
other two required contexts on `main`, so a dropped step there sends a required
check green having done no work.

Per-STEP markers, not per-job as proposed: a marker on the first step only
proves the job began, while the drop that costs something is `Test`, `Build` or
a migration replay. The trailing guard carries no `if:` — with a dozen steps,
`always()` would announce a false "these steps never executed" on every ordinary
red build; the default `success()` is correct because guard-skipped implies
job-red. Plus a ban on the raw `${{` opener in `test`, `migrations` and `build`,
which makes the class unreachable rather than merely caught. `build` is included
because its Smoke step runs AFTER the image is pushed.

Measured live on the build lane in both directions: probe #765 (drop caught,
sole failure in the job) and #766 (a failing continue-on-error step does not
skip the guard). 510 tests, 30 mutations killed across two harnesses, five cold
review rounds across two model families.

Residual tracked as #767: the `build` ban is review-time only, not fail-closed
on the release path.

timothyandClaude Opus 5 e133c11fde fix(751): rebase onto #760, close the fail-OPEN twin, and retire four claims that had rotted
Fourth cold review round: no Blocker, no new path to a green `review-verdict/h10` on an
unreviewed head, and it independently re-measured 14 claims in the diff. It also caught
that this branch was about to revert someone else's work, and found the one remaining
place where the nil-slice/clamp lesson had not been applied.

REBASED ONTO 9881d1ff8 (#760), which landed while this was in review. The tell was the
one CLAUDE.md documents: `git diff origin/main HEAD` showed deletions I never made —
`docs/decisions/records/mcp/tool-schema-openapi-parity.md` and edits to `docs/mcp.md`.
Pushing would have reverted them. The generated catalog was regenerated rather than
trusted to the rebase, and verified to carry BOTH records.

THE FAIL-OPEN TWIN, one function further on than the last round reached.
`/statuses/{sha}?limit=100` is read twice — for the high-water mark and for the
post-write race check — and neither pages, while `limit` clamps to 50. So "no raced row
on page 1" does not establish "no race": a human `BLOCKED` landing in the write window
can sit on a page the job never reads, leaving a forged green over a rejection. This is
the ONE path in the design whose failure direction is toward SUCCESS.

Measured rather than argued: a probe head reached 33 rows after ~5 runs against a cap of
50, and the ordering is only coarsely newest-first (`33,32,31,30,28,29,27,…`), so a few
CI reruns reach it and the row's position cannot be relied on — which this workflow's own
comment already disclaimed. That comment ALSO claimed order-independence flatly; false
once the page clamps, so it now says what actually holds and what saves us.

The mitigation is conservative rather than complete: if page 1 shows no race, page 2 is
read, and any rows there — or an unreadable page 2 — count as "assume raced" and repair
to `pending`. Uncertainty resolves to a stall a reviewer can clear, never to leaving
green. Real paging of both reads, including the high-water mark, is #763.

A THIRD empty shape turned up while modelling it: `/statuses/{sha}` past the end returns
`[]`, where `/commits/{sha}/status` returns `{"statuses": null}` and the timeline returns
bare `null`. Three endpoints, three shapes, one server. The code tolerates both here
because guessing per endpoint has now been wrong twice.

MY OWN COVERAGE GAP, found by mutation rather than by reading: inverting the
unreadable-history-page-2 branch reddened NOTHING. Now tested both ways. Same class as
the two untested refuse branches the review flagged, which are also covered now.

FOUR CLAIMS RETIRED, all of the shape this issue is about — text that reads as checked
and is not:

* "18 tests fail" for the corrected-double mutation is 21 now, because rounds 3-4 added
  three fence-dependent tests. Broke a number while documenting broken numbers. Both
  citations now give the range and lead with the invariant.
* "measured: 4, 2, 9, 5, 10" first-page timeline events are 7, 5, 9, 6, 10 today.
  Timelines grow; the figures are gone and the invariant stated instead — a PR is created
  by a push, and a push is an event, so page 1 is never empty.
* The strict test's docstring said "RAW TEXT" while the test reads parsed `run:` scalars,
  with a dead `raw =` assignment left behind (a new ruff F841).
* `len(bodies) >= 3` had zero slack: deleting the optional jq-preflight step reddened it
  with a message asserting the classifier had not been examined, which was untrue. The
  length assertion already carries the property, so the count only needs to be non-empty.

Also: dead `_workflow_expression_fields_text` removed; assertion C's regex now catches
`function foo {` as well as `foo() {`; the page-2 refusal says a human verdict clears it.

Verification: 460 green. Five more mutations as intended — deleting the history page-2
check (red), accepting an unreadable one (red, after the coverage gap was closed),
accepting a garbage page 2 in read_existing_verdict (red), hiding the marker write behind
`function mk {` (red), and the earlier twenty-one still hold. Live re-probe on this body

timothyandClaude Opus 5 951dae26a9 fix(751): the truncation guard I added was DEAD CODE — the page cap is 50, not 100
Third review round, cut short by a transport hang after ~11h, but it had already found
the thing that mattered: the guard added last round could never fire.

`read_existing_verdict` asks for `limit=100` and refused when the page came back with
100 rows. This instance caps `limit` at the server-wide `MAX_RESPONSE_ITEMS`, MEASURED
AT 50 — `/issues?limit=100` returns 50 items. A response can therefore never carry 100
rows, so the comparison was unreachable and the hole it was written for was still open.

The sting is that the repo already knew. `scripts/pr-changed-files.sh`, two test files
and `ci.script-tests-job` all document that Gitea caps `limit` at `MAX_RESPONSE_ITEMS`
(50 in the PR #619 measurement). The review found it by grepping this codebase, not
upstream. Writing a guard against a constant the repo had already measured as wrong is
the same failure as the unfaithful test double two rounds ago: a number believed rather
than checked.

So this is now the THIRD guard for one hole, and the first two were both no-ops:

  1. `.statuses | length` vs `.total_count` — `total_count` is the count for the PAGE
     RETURNED, not the commit (`?limit=1` on a 6-context head gives
     `len=1, total_count=1`). Equal by construction.
  2. "refuse when the page is full at 100" — dead code, as above.
  3. Ask the server. Completeness is needed ONLY to justify "no verdict exists on this
     head", so when the row is absent from page 1 the job reads PAGE 2, and refuses if
     it carries anything. Cap-independent: no reconfiguration re-breaks it, and nothing
     is hardcoded that a measurement could contradict.

Measured to make sure page 2 is real rather than assumed: `?limit=3&page=2` on
3aed43c6 returns three further rows, and `page=9` returns the same `statuses: null`
terminator the timeline uses.

The probe is skipped when the row IS on page 1, because there is nothing to learn — the
combined endpoint returns the latest status per CONTEXT, so a context cannot recur on a
later page.

TEST-DOUBLE FIDELITY, again the fiddly part. The stub now honours `page`, and that guard
had to go BEFORE the read-counting modes: `appears-on-read:N` counts how many times the
job has LOOKED at the status, and the completeness probe is part of the same look, not a
further one. Letting it increment those counters shifted "the verdict appears on read N"
by one and broke three mid-run-race tests — a false red that would have been easy to
"fix" by adjusting the expected counts, which would have quietly destroyed what those
three tests measure.

Verification: 455 green. Four more mutations, each as intended — deleting the probe
(red), accepting a non-empty page 2 (red), refusing even on an EMPTY page 2 (red, the
deadlock control), and reverting the twin `statuses: null` gate (48 red). Twenty-one
mutations across four rounds.

timothyandClaude Opus 5 46ec532745 fix(751): re-review round — a truncation hole, and the tests that closed findings needed closing
Cross-family re-review of the previous fix commit. It did NOT pass, and it was right
not to: the round that fixed the reviewers' findings introduced two of its own, both in
the tests written to close them. That is this file's recurring shape, and it is the
reason the fix commit gets re-reviewed rather than the initial diff only.

TRUNCATION (High). `read_existing_verdict` asks for 100 statuses and never checked
whether the page was full. If a head ever carried more contexts than that, an existing
`review-verdict/h10` could fall off page 1, the job would conclude no verdict exists,
and it could post an exemption `success` over a human `failure` — the worst thing this
gate can do. Six contexts exist today, so this guards a future shape, not a live bug.

BUT THE PROPOSED GUARD WAS A NO-OP, and measuring is what showed it. The review asked
for `.statuses | length` compared against `.total_count`. On this instance `total_count`
is the count for the PAGE RETURNED, not for the commit: on 3aed43c6 (6 contexts),
`?limit=1` gives `len=1, total_count=1` and `?limit=3` gives `len=3, total_count=3`.
The two are equal by construction, so that check would have read as a completeness
proof while proving nothing — and it would have been the second guard in this file to
look like a check and not be one. What IS observable is a page at the requested limit,
which means "maybe more", so that is now treated as unreadable: post nothing, leave the
required check absent. The stub mirrors the per-page `total_count` deliberately, so the
new test cannot pass for the wrong reason either.

THE TESTS THAT CLOSED THE LAST ROUND'S FINDINGS:

* The behavioural guard test — added to answer "a bare `exit 1` substring is satisfiable
  by dead code" — extracted the two marker lines BY TEXT and ran them alone. That
  passes even if the write is moved into a function nobody calls: the extractor finds
  the text, runs it at top level, the marker appears, and the test reports the guard
  proven while production writes no marker. It now executes the classify body's real
  PREFIX down to and including the write, which reproduces the production control flow
  instead of a reconstruction of it. Mutation: move the write into an uncalled function
  -> RED (it previously passed).
* The anti-vacuity check — added to replace an over-broad assertion — hand-counted
  `run:` keys with a regex that only matched an indented `run:` starting `|` or `>`. It
  false-redded legal spellings (`- run: |`, a single-line `run: echo ok`) and could
  count a `run: |` sitting inside a heredoc. Hand-parsing YAML to validate a YAML parse
  is the wrong shape: it adds a second, worse parser whose every disagreement is a
  false alarm, and a red here blocks all merges. Now asserted on CONTENT — the walk
  reached >=3 bodies and one over 5000 chars.

FALSE RED, THIRD INSTANCE IN THIS FILE. The repo-wide expression test scanned raw file
text, so a delimiter in an inert top-level YAML comment redded the repo even though the
runner never evaluates it. It now scans PARSED scalars: PyYAML drops YAML comments,
while a `run:` body is itself a scalar and keeps its SHELL comments — which is exactly
the distinction that matters, since inside a `run:` scalar a comment is not inert.
Verified in both directions: an inert top-level comment passes, the same payload in a
run-body comment still reds.

Also: the `total_count` zero check now requires the JSON TYPE to be number — `jq -r`
renders `0` and `"0"` identically, so a text compare accepted a corrupted
`"total_count": "0"` as "no statuses".

Verification: 455 green. Six further mutations, each landing as intended — the uncalled
function (red), an inert YAML comment (PASSES, no false red), the same payload in a
run-body comment (red), accepting a full status page (red), comparing total_count as
text (red), and breaking the YAML walk's job key (red). Seventeen mutations across the
three rounds.

Re-probe of both live controls follows on this body; the previous probe evidence was
taken before this commit and no longer describes what would merge.

timothyandClaude Opus 5 edd8d3d9c9 fix(751): review round — the twin null-shape, a governance self-exemption, and four over-claims
Two independent cold reviews (a cross-family GPT-5.6 pass and an isolated Opus pass).
Neither found a path to a green `review-verdict/h10` on an unreviewed head. Both found
real defects BESIDE the fix, which is the failure mode this file keeps producing.

THE TWIN, and the reason not to trust "I fixed the two I could see". `GET
/commits/{sha}/status` returns `statuses: null` — not `[]` — for a head with no
statuses yet: `{"state":"pending","total_count":0,"statuses":null}`, measured on PR
#739's head. `read_existing_verdict` gated on `.statuses | type == "array"` and took
its `exit 1` path, posting NOTHING. Fail-closed, but the user-visible outcome is the
one this issue is about: an exempt PR with no status and, since #743, no bypass. Its
double printed `{"statuses": []}` at all three no-verdict sites, so that branch was
unreachable in the suite — the same unfaithful-double story as the timeline, one
function over. `null` is accepted only when `total_count` is 0, so a body that merely
lost its array is still refused and an existing verdict is still protected. Swept
`scripts/pr-changed-files.sh` too: `pulls/{n}/files` returns `[]`, unaffected. The
generalisable rule is that a nil Go slice serialises to `null`, so every list-shaped
field on this API is suspect and only a per-endpoint measurement settles it.

A GOVERNANCE SELF-EXEMPTION, reachable again precisely because this change works.
`DOCS_ONLY` matched `CLAUDE.md` and `AGENTS.md` — the documents that DEFINE the
completion protocol, the merge-consent convention and the H10 rule. Driving the real
classify body with a lone `CLAUDE.md` change produced `review-verdict/h10=success`.
Protecting `.claude/` while the file specifying what it enforces stayed exemptible is
the same self-exemption the header rules out, one directory over. Both added to
PROTECTED; `README.md` deliberately not (ordinary prose, no enforcement).

FOUR OVER-CLAIMS, corrected rather than defended:

* The repo-wide expression test does NOT catch "any payload that cannot evaluate".
  It checks the HEAD TOKEN of each dotted path. `${{ github.ref == }}` and
  `${{ …head.sha + }}` pass; so does a renamed output, since tokens after the first
  are skipped by design. Claim corrected in the docstring, `docs/ci-cd.md` and the
  record. The test is kept permissive on purpose: a red here blocks every merge.
* The strict test's anti-vacuity half banned expressions ANYWHERE outside
  `with:`/`env:`, so the standard `if: ${{ always() }}` spelling and even a delimiter
  in an inert top-level comment went red — a guard more dangerous than its target.
  Replaced with the honest property: the YAML walk saw every `run:` body it declares.
* The `if:` assertion demanded the bare `always()` exactly; now normalised, since the
  wrapped form is identical to the runner.
* `exit 1` was matched anywhere in the guard body, so an unreachable
  `if false; then exit 1; fi` satisfied it while the real branch said `exit 0`. Now
  required INSIDE the missing-marker branch — and the new behavioural test settles it
  properly by EXECUTING the guard body both ways.
* The record asserted a repo-wide obligation to guard consequential steps. It is not
  repo-wide: `docker-build.yml`'s `test`/`migrations` are also required contexts and a
  dropped step there is fail-OPEN (green having done no work), strictly worse than
  here. Scoped to this file and tracked as #756 rather than asserted as done.

Also: comments in both files still said it was unestablished whether a later step runs
after a drop — runs 1863/1866 established it, so they now record the measurement; a
cited test name that never existed; `kind` leaked to global scope; a mangled comment
wrap; and an already-false "one event on page 1".

Hardening of my own: `null` now counts as exhaustion only from page 2 ON. Every real
PR's first page carries events (4, 2, 9, 5, 10 across #752/#753/#749/#739/#717), so a
terminator on page 1 means no page was ever read, and certifying "no retarget" from a
response we cannot explain is the one thing the fence exists to refuse. Narrows rather
than closes it: a wrong `null` on page 3 still reads as exhaustion.

Verification: 137 in this file / 452 total green; ELEVEN mutations each red —
reintroducing the defect, deleting the guard, deleting the marker write, removing
`if: always()`, `exit 1`→`exit 0`, a delimiter in the guard body, the fence gate (20
red), the TWIN gate (70 red), dropping the governance paths, accepting a null first
page, and diverging the marker path between the two steps.

timothyandClaude Opus 5 40b3747434 fix(751): the fence never trusted its count — a page past the end is null, not []
The scratch-base probe found a SECOND, independent reason `review-verdict/h10` was
never posted automatically. Fixing the dropped step alone would NOT have restored the
exemptions.

`count_retargets` pages `/issues/{n}/timeline` and trusts its count only on a
validated empty page, gated on `type == "array"`. But a page past the end of that
endpoint is the JSON value `null` — measured at Gitea 1.27.1 on PR #752, four bytes —
so the real terminator read as UNREADABLE. The walk never reached a validated empty
page, `rt_ok` was never `yes` for ANY pull request, and the fence therefore withheld
EVERY exemption `success`. Renovate and docs-only PRs got no status at all: the same
user-visible outcome as the dropped step, by a completely unrelated route.

The instance is not consistent between endpoints — `/issues/{n}/comments` returns `[]`
when empty — so both shapes terminate the walk now, and the regression test is
parameterised over both. The type is read as a VALUE (`case` over `jq -r 'type'`)
rather than through `jq -e`, whose exit-status semantics already bit this workflow at
jq 1.6 (#647).

TWO REASONS THIS LOOKED DELIBERATE RATHER THAN BROKEN, both worth generalising:

* It had never run. This fence shipped in 8f6d4f443 — the same commit whose prose
  comment stopped the classify step executing at all. Merging a guard and first
  executing it are different events, and only the second tells you anything.
* The test double asserted the wrong shape while claiming to be measured. Its comment
  read "Real shapes, measured on this instance and deliberately mirrored" and it
  printed `[]` past the end, so the `array`-only gate was never exercised by the suite
  either. Correcting the double and restoring the old gate turns 18 TESTS RED — every
  one of them had been green for the wrong reason. A fidelity claim in a double is an
  assertion and it decays like any other.

The new test asserts the POSTED STATUS, not the log: on the real probe run the log
said `Decision: state=success` and the job still posted nothing, so the decision and
the write are separate events and only the write is what a merge reads.

Also here, both found while editing this code:

* `ci.verdict-write-retarget-fence` stated this as a narrow residual ("a timeline over
  the 20-page cap can never be exempted") when the behaviour was universal. Corrected
  in place rather than left as a checked-looking claim that talks the next reader out
  of verifying.
* The workflow cited `ci.paged-endpoint-completeness`, a key that has never existed as
  a record anywhere. Repointed at the record that actually owns this walk.

Marker hardening from the probe: `RUNNER_TEMP` is `/tmp` on this runner, not a private
per-job directory, so the start marker is now keyed on the run id and attempt. The
lane starts a container per job today, which makes a fixed name fresh in practice, but
that is a property of the lane and a stale marker would make the guard PASS on a run
whose step was dropped — the exact silent pass it exists to remove.

Verification: 446 passed; M7 (revert only the type gate, keep the corrected double) →
18 red. Probe evidence in the issue.

review-verdict/h10 Review-verdict: MERGEABLE @ f822e47 (base: main)
Round 3 returned MERGEABLE with three LOW documentation findings. Batched
before posting the verdict, since a new sha voids both the CI run and the
verdict.

- `ci-cd.md` labelled the unprobed half of the `enable_push` bullet but stated
  the `block_admin_merge_override` counterfactual flatly one bullet below —
  the same measured-vs-attested flattening round 2 fixed, one site over. Now
  labelled, with why it was not probed (verifying it means merging an
  unreviewed PR).
- `release.verdict-status-check` said "what survives is the forgery list
  above". That record's job is enumerating survivors, so an unqualified "what
  survives is X" reads as exhaustive — and it omitted the admin residual, which
  is a SKIP route rather than a forgery one. Added.
- `CLAUDE.md` never learned the rule. It is the always-read surface, and it
  still framed a direct `git push origin main` as a live path while describing
  a docs-only *push* exemption for a push the server now refuses. My corpus
  sweep covered `docs/` and missed the file that carries the docs-update rule.

Note on what remains unverified rather than closed: neither direction of
`block_admin_merge_override` was measured, and whether Gitea treats an ABSENT
required context as blocking (versus satisfied) is asserted by our docs but
not proven — the combined status on this PR reads `success` with
`review-verdict/h10` absent. Both belong to #747's re-verification sweep.

Verification: 441/441 script tests; decisions-validate OK.

Round 2 of review. One blocking finding, and it is the same defect class as
round 1's: a present-tense claim that this PR falsified.

`release.verdict-status-check` — the record ABOUT the h10 status check — still
said "direct pushes to `main` are server-side permitted, so the gate can be
skipped without forging anything". A reader resolving that key from the catalog
would conclude the control does not exist. Round 1 corrected `ci-cd.md` and
`ci.actions-credential-scoping` and I stopped at the two sites I had edited,
instead of sweeping the corpus by SUBJECT. Swept properly this time
(`server-side permitted`, `bypassable`, `without forging`, `push whitelist`,
`enable_push`): this was the only remaining stale site.

Test gaps the reviewer found by mutation testing, now closed. Both mutants
SURVIVED the suite as shipped — the round-1 fixes were correct but unpinned:

- dropping `|| [ -n "${_h11_local_ref:-}" ]` → an unterminated final line is
  dropped. Two directions, and the dangerous one is not the obvious one: a
  dropped *branch* line leaves only tag refs and grants the exemption to a push
  containing a branch. Both pinned.
- dropping `[ -t 0 ] ||` → the hook hangs forever on an interactive run. Pinned
  with a real pty and an explicit timeout, so a regression fails cleanly rather
  than hanging a CI job. Verified the mutant is killed by exactly that test
  (and that it dies via the timeout, 32s).

Also from review, non-blocking:

- `ci-cd.md:951` cited `enable_push: false` alone as what closed #743 — the
  precise thing the new record says never to do, since the force-merge route
  also skipped the gate with no forgery. Now cites both fields.
- `ci-cd.md` flattened measured and source-attested into one 403: only the
  contents API was probed; the web editor/upload/apply-patch paths share the
  predicate but were not. Separated.
- `format-as-you-touch-rebase` still said "the documented sequence" and
  "always" for the release-cut behind-ness. `docs/ci-cd.md` documents the tag
  step, not the release-notes-PR flow, and the frequency is attested by one
  observed cut. Attributed to #719 instead.
- Documented the operator recovery path. `block_admin_merge_override: true`
  removes the `force_merge` escape that used to unstick a wrongly-red required
  context — that escape WAS the bypass, so it is gone by design, and the
  recovery (fix the status; last resort PATCH the field, merge, set it back)
  needed to be written down rather than left implicit in a residual.

Verification: 441/441 script tests; decisions-validate OK; PyYAML parses all
193 records; both mutants confirmed killed and the hook restored byte-identical.

timothyandClaude Opus 5 6d80343320 fix(743): close the admin force-merge bypass; the push half alone was not enough
Independent review found the record repeated on the merge path exactly the
mistake it had just diagnosed on the push path.

The push argument was: a whitelist naming `timothy` closes nothing, because
`timothy` is the identity every credential already holds. The merge path had
the identical shape and went unchecked — `block_admin_merge_override` defaults
to `false`, so `CanBypassBranchProtection` returns true for a repo admin and
`POST /pulls/{n}/merge` with `force_merge: true` merges straight past a missing
or red `review-verdict/h10`. One API call, no forgery, no PATCH — cheaper than
the push route this change had just removed.

So `enable_push: false` alone did NOT make the gate load-bearing, which is
what the record's headline sentence claimed. `main` now carries both fields;
they are one control and neither is citable alone.

An admin-shaped control that exempts the only admin exempts everybody.

Other review findings addressed:

- H11's owning record (`release.format-as-you-touch-rebase`) now documents the
  #719 tag-only carve-out. It is a narrowing of an existing convention, so it
  amends that record rather than adding a new one — including the two details
  that are easy to regress (the .husky/pre-push forwarding, without which the
  exemption is dead code the unit tests still pass over; and the at-least-one-
  ref guard against vacuous exemption).
- The record now states which write surfaces were enumerated and how each was
  established — contents-API refusal is MEASURED here (403 `user cannot commit
  to repo`), apply-patch/revert/cherry-pick are source-attested only. The
  admin force-merge bypass is likewise marked source-attested, not probed:
  probing it means merging an unreviewed PR.
- prepush-rebase-check.sh: process a final ref line with no trailing newline
  (previously dropped, which silently reinstated the #719 block), and skip the
  stdin read on a TTY so an interactive run does not hang.
- Corrected a citation the review caught: docs/ci-cd.md documents the tag step,
  not a release-notes-PR flow. Cite #719 for the observed flow instead.

Also fixed a frontmatter break this round introduced: a `: ` inside the
unquoted `rule:` scalar. PyYAML rejected it while the dependency-free reader
accepted it, so only `scripts/tests` caught it.

Verification: 438/438 script tests pass; decisions-validate OK; PyYAML parses
all three touched records.

timothyandClaude Opus 5 691a7acc77 fix(743): disable direct pushes to main so review-verdict/h10 is on the only path to main
Gitea evaluates `status_check_contexts` when it MERGES a PR. A direct
`git push origin HEAD:main` never consults them, so the whole h10 gate was
skippable with no forgery — strictly cheaper than every route enumerated in
#697. `main` now carries `enable_push: false`.

Measured on this instance (Gitea 1.27.1) against a throwaway `probe-743-*`
rule rather than against `main`:

  enable_push: false                      -> push by timothy (site admin)
                                             REFUSED, pre-receive hook declined
  enable_push_whitelist + ["timothy"]     -> identical push SUCCEEDED

That second line is why this is a DISABLE and not a whitelist: #743 offered the
two as interchangeable, but the only write accounts here are `timothy` (site
admin) and `renovate`, and every credential in the threat model — agent
sessions, PATs, the injected GITEA_TOKEN — acts as `timothy`. A whitelist
naming `timothy` would have ticked the box and closed nothing.

Then demonstrated on `main` itself, per the issue's Done-when: a direct push
was refused, and a tag-only push from the same worktree succeeded (tags are
governed by `tag_protections`, which is empty). The release cut is unaffected.

What this closes: the write-only credential routes — the injected GITEA_TOKEN,
RENOVATE_TOKEN, any non-admin collaborator PAT. What it does NOT close: an
admin credential can PATCH the protection off, push, and restore it. Recorded
as an accepted residual rather than implied to be covered.

Also corrects two claims the probe contradicted, and one that the mid-session
Gitea upgrade (1.25.4 -> 1.27.1) invalidated:

- ci-cd.md and ci.actions-credential-scoping both said "a push whitelist would
  close more of this class than the 1.26 upgrade". The whitelist form closes
  nothing here; corrected in place.
- ci.actions-credential-scoping's rule said "do NOT add a `permissions:` key
  while this instance is below Gitea 1.26.0". That precondition no longer
  holds at 1.27.1, so the directive now misleads. Corrected — while noting the
  consequence is still UNVERIFIED: `/api/v1/settings/actions` 404s at 1.27.1,
  so whether `permissions:` binds here was not probed. The upgrade alone is
  not evidence the constraint works.
- That record's 1.25.4 measurements are now dated, not current. Flagged as
  such rather than silently re-pinned to a version they were never taken on.

#743's fourth box (docker-build.yml `persist-credentials: false`) is decided
in the record and deliberately not done here: two of its checkout steps run
`git fetch ... || true` feeding the changed-file skip logic, so a credential
regression would be silent rather than loud. Drop the `|| true` masking first.

fixes #743
