`docs.no-session-narrative` reaches every durable artifact, but its detector scanned only
`docs/**/*.md` and root markdown, and nothing had ever swept the rest. The issue named four sites
from one grep and called them a floor. Deriving the population instead — a whitespace-joined sweep
over every tracked file outside the detector, for the detector's own phrasings plus the attribution
and review-round class #812 found — gave 453 sites in 108 files at `fb5592971`, and a second pass
for phrasings the first list missed (hyphenated `round-N`, "an earlier version", "the reviewer
proved") added residuals in the same files. Every site was classified with #812's three
dispositions (CUT / SEVER / KEEP with its sub-kind) under the who-benefits test; the per-site
manifests are on the PR. The rejected designs, tested-and-rejected fixtures, measurements and
traps stay; the attribution of who found them and the round in which they were found go.

The detector's population grows to `.claude/`, `.gitea/`, `.husky/` and `scripts/` regardless
of extension, minus the detector and its own test (whose fixtures ARE the phrasings) and minus
`scripts/tests/fixtures/` (test data, including decision-record copies — the same reasoning as
the records' own exemption, and what keeps the record's depth measurement true), and `--all`
lists tracked REGULAR files only — a symlink's content is its target and a gitlink has none. The #812
argument for leaving `docs/superpowers/**` in the population runs the other way here: `--diff`
sees only ADDED lines, and 287 of the 453 sites were under 30 days old — this corpus is where
narrative is being added, so the advisory nudge has reach. Density agrees: 56 line-mode hits over
the 113 regular files the predicate admits, against 9 over 66 docs files before #812. `web/` and C# stay out on the same
measurement (3 of 74 PATTERNS-matching sites, ~4,600 files). The predicate did not grow: PATTERNS
matched 74 of 453 sites, and widening the word list to the attribution class is the treadmill
the withdrawn parity test ran on. The population oracle is restated over segments with the new
arms, the synthetic cross product gains the process heads and non-markdown extensions, a fixture
witnesses that a tracked symlink is neither scanned nor counted, a `.py.bak` axis separates a
by-name exemption from a `startswith` over the same tuple, and eight mutants (drop the process
arm, drop the by-name exemption, exempt by `startswith`, drop or add a prefix, drop the fixtures
exemption, list only markdown, drop the symlink filter, test the mode per row instead of per
path) each
redden it. A pre-existing silent drop in `--diff` goes with it: git tab-terminates a `+++`
filename that contains a space, and the kept tab made `is_scanned_path` refuse the file with no
notice — fixed, with a positive control and its own mutant.

Code is unchanged by construction, measured per file type against `origin/main`: Python modules
are AST-equal with docstrings stripped, except `#` lines inside the embedded fixture programs
(string literals) of three test modules; workflows differ only in `#` lines inside `run:` block
scalars; shell, C#, TypeScript and jq are equal with comment lines stripped. The stated
exceptions: the detector and its test, 26 vitest titles that carried review-round or severity
labels or a reviewer attribution (call sites whose title changed — every changed title line
walked back to its `it(` / `it.each(...)(` anchor, so a `' + '` concatenation counts once), two
registry note strings and the mutation manifest's prose fields. scripts/tests: 1565 passed.
Web: lint, typecheck, 1319 tests green. Closes #876.

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

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

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

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

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

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

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

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.

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

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 0c5938dd60 fix(774): the wiring check counted a MENTION, reproducing inside the fix the defect it closed
Self-audit before re-review, and it found one. `wired_hook_files()` was added to stop hook
EXISTENCE standing in for hook WIRING — but it substring-matched the filename against the
whole husky text, and `.husky/pre-commit:7` reads

    # CI where a base ref exists). Fail-open shim — see .claude/hooks/decisions-guard.sh.

one line above the real invocation. Delete line 8, keep line 7, and the hook still reads as
wired. That is mention-for-invocation, which is the exact substitution the function exists
to prevent, one line inside the fix for it. Comment lines are now stripped from the husky
hooks first; settings.json needs no stripping because JSON has no comments.

Proven both ways: with the invocation removed and the comment left, the guard names
decisions-guard.sh as unwired; clean tree stays green.

Also verified rather than assumed, since a fix round is where adjacent defects live:
  - a stale SELF-referencing proof ref is still caught (the self-reference escape hatch
    skips only the PROOF-row classification check, not the def-existence check);
  - a reworded summary is LOUD, not vacuous — an unparsed summary fails with a message
    saying so, rather than silently checking nothing.

ruff clean, pyright clean (0 errors) on the three new files. Deliberately NOT ruff-format-ed:
the pre-existing scripts/tests corpus is not formatted either, so reformatting only these
three would diverge them from every sibling and bake in a format derived from an
un-versioned config on one machine — which is the divergence #780 exists to settle.

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.
