3 people	15d2439915	feat(794): witness a fix's test failing BEFORE the fix, and check the claim in CI (#801) ... 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). fixes #794 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-16 10:24:59 +00:00
timothyandtimothy	cfdab63a3a	fix(767): gate the release path on the delimiter ban with a prerequisite job (#770) ... 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.

timothyandtimothy	f9f8f65cee	docs(720): name all three Komodo stacks and the label-based resolution rule (#769) ... 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. fixes #720 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-11 19:26:07 +00:00
timothyandtimothy	884ac8a7e9	fix(756): extend the dropped-step guard to docker-build.yml's required jobs, where a drop is fail-OPEN (#768) ... 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. fixes #756 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-10 23:35:08 +00:00
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 follows. Refs: #751 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-10 19:42:58 +02:00
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. Refs: #751 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-10 19:22:50 +02:00
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.

timothyandClaude Opus 5	f822e4737c	docs(743): label the second attested claim, close the survivor list, state the rule in CLAUDE.md ... 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.

timothyandClaude Opus 5	6af65ba5c5	fix(743): re-tense the third stale site, and pin the two surviving mutants ... 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. fixes #719 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-06 00:10:45 +02:00
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.

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 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-05 23:31:45 +02:00
timothyandClaude Opus 5	b91939e5c4	fix(697): correct the overclaims three adversarial review rounds found ... Round 1 BLOCKED (1 Blocker, 4 High, 3 Medium, 2 Low); round 2 BLOCKED on the fix (1 Blocker, 2 High, 4 Medium, 2 Low); round 3 BLOCKED on one Medium. Every finding re-verified against the live instance before acting. ROUND 2 — the blocker was self-inflicted and the local gate could not see it. Adding `branches: [main]` to ci-image.yml re-points `ci-image-pin`'s `expected` at the editing commit, staling all five `container:` pins and failing that BLOCKING job — for a change altering zero bytes of the toolchain image. Reproduced: expected=ed9dd6254 vs pins=32747a0. Reverted here (the commit was amended, so no commit on the branch touches that path) and filed as #744. That edit had also FALSIFIED its own justification: branch publishing IS load-bearing — docs/ci-cd.md documents the rebase-recovery flow as "let ci-image.yml publish :<short sha>, then bump the pin", which is how you satisfy ci-image-pin from inside a PR. Reverting also keeps three trigger descriptions true (ci-cd.md:1043, the recovery flow, pr-checks.yml's escape-hatch comment). Also fixed: - gate-trigger-base-resolved.md was the file round 1's fix did not touch, and still said "no workflow route retains human provenance" — false, since a PR-added workflow can reference RENOVATE_TOKEN. Its `rule:` also kept the race framing, and `rule:` is what the catalog and MemPalace mirror. - `mechanics:` claimed "independent review confirmed no CI consumption breaks". It confirmed no such thing. Round 3 then caught the REPLACEMENT sentence making the same class of error: only the `container:` pull is exercised by a PR, because `build` carries `if: github.event_name != 'pull_request'` and cache-to/cache-from live only there. Those and the base-image pull first run on the post-merge push to main — a wrong inference reddens main, not the PR. - A fourth surviving route was unnamed: docker-build.yml publishes :prod from a `v*` tag push and a tag may point at any commit (tag protections are empty). "three surviving routes" became "at least these" — a count reads as complete. - Unmarked inferences, a "three later sections" that undercounted four, a dangling "the two items below", and a #744 rationale that stated the pin toll without its documented remedy. Local gate: 432 script tests pass; `decisions_validate.py --base origin/main --head HEAD` and `build_decisions_catalog.py --check` both exit 0; ci-image-pin recomputed by hand and matching the pinned commit. The record is 62 prose lines against a 60-line ceiling that is a `::warning::` by design (#520) — the blocking constraint is the 2-25% minority band, currently 10.8%. Refs #697, #742, #743, #744.

timothyandClaude Opus 5	e298bb291e	fix(697): scope CI's registry credential so head-resolved workflows cannot forge review-verdict/h10 ... `REGISTRY_USER`/`REGISTRY_PASSWORD` were the ADMIN account's basic auth, and `docker-build.yml` triggers on `pull_request` — head-resolved — so a PR's own code was handed instance-admin credentials. Basic auth carries no scope, so the same secret that pushes an image administers every repo on the instance and can POST `review-verdict/h10`, the required context that makes merge-consent derived rather than assertable. Refs #697. Fixed at the credential, not the triggers: patching triggers enumerates instances of "a ref-resolved workflow obtains status-capable credentials", and adding a new workflow file is itself a route. `REGISTRY_PASSWORD` is now a PAT scoped `write:package` + `read:repository`. Verified on Gitea 1.25.4, not inferred: - registry push of a probe tag SUCCEEDED (cleaned up, confirmed 404) - GET /commits/{sha}/status SUCCEEDED (what ci-detect-already-validated.sh does) - POST /statuses/{sha} REFUSED, HTTP 403: required=[write:repository], token scope=write:package,read:repository Scope of what this closes, stated without overclaim. It closes the instance-wide admin escalation and that credential's durable forgery route — durable because a status POSTed with a USER credential carries a real `creator` and is inherited as a human verdict, while an Actions job's carries `creator: null` and is re-derived. It does NOT close the class. Three things survive it: - `RENOVATE_TOKEN` is a `write:repository` PAT of a real bot account in the SAME secret store, so it also posts with non-null `creator`. It cannot be scoped down (Renovate needs repo write), and secrets are a per-repo store that any PR-added workflow can reference. Closing this needs the provenance check tightened to an allow-list of approved reviewers. - Every job still receives a write-capable `GITEA_TOKEN`. `permissions:` YAML is a no-op before Gitea 1.26.0 and no `app.ini` lever exists at any version; only >=1.26 with the Actions default set to Restricted binds it. Tracked in server-management#714. - Branch protection binds the context NAME, not its issuer, so any write-scoped personal token forges the status with genuine human provenance. Unfixable in-repo. `h10` is a process guard, not a security boundary against push access. Auditing the secret STORE rather than the workflow set also surfaced `SERVERMGMT_DEPLOY_KEY`, still present though the `bump-prod-compose` job that used it was removed in 1b5efd7b9 — an SSH deploy key to another repo, obtainable by any PR-added workflow, with no remaining benefit.

timothy	5fa672e2e5	docs(release): record the v26.14.0 release notes ... Adds the v26.14.0 row to the release table. This is the commit the v26.14.0 tag will be pushed onto, matching how v26.13.0 was cut (#716). Contents since v26.13.0: the #726 bitmap-subtitle -readrate starvation fix (headline), the #674/#688 decisions-validator PyYAML cross-check, the #706/#707/#711 review-verdict raced-sentinel fix, and two Renovate bumps. Replaces the branch behind PR #738, which never received a pull_request CI run across six trigger attempts (two pushes, a force-push after rebase, a close/reopen, a body edit, and a spaced push on an idle queue). A workflow_dispatch run did complete green but writes no commit statuses, so it cannot satisfy the required checks. Opening a fresh PR produces an `opened` event rather than a synchronize, which is a different path. No [skip ci] token -- this branch's merge commit is the v26.14.0 tag target.	2026-08-05 00:44:00 +02:00
timothyandClaude Opus 5	0ff9671393	fix(688): pin the minority band's constants and inclusivity; two prose corrections ... Review round 7. Its adjudication of the round-6 dispute went the branch's way — measured at `f394d6ce`, the sha the record actually cites, the #620-era distribution is n=167, min 2, median 26, p90 52. Round 6 had measured `fefd11dff` (p90 57), a different tree. The number stays as written. BLOCKING FINDING: the 2%/25% constants and their inclusive boundaries were not pinned at all. Mutating 0.02 -> 0.03, 0.25 -> 0.30, or either `<=` to `<` passed all eight calibration tests. Those are not free parameters — they ARE the documented CI-red thresholds, so a silent shift would quietly falsify the 38/718 figures in docs.corpus-size-signal and docs/ci-cd.md (a strict cap reds after 37 long additions, a strict floor after 717 short ones). test_the_minority_band_BOUNDARIES_are_exactly_where_documented pins all four. It uses 100-record fixtures so k over the ceiling IS k%, and both 2/100 and 25/100 are exactly representable and compare equal to the constants — true boundary cases, not near-misses. Verified by mutation: all four now fail it. PROSE - corpus-size-signal said what stays blocking is "what routine growth cannot break", immediately before explaining that 38 routine additions break it. Now "what no SINGLE ordinary addition can break", which is what is actually true. - docs/ci-cd.md said the fine claim is "never asserted"; it is never asserted AGAINST THE LIVE CORPUS, and IS asserted on synthetic distributions the tests own. Corrected — the distinction is the whole design. Correction to an earlier commit message in this branch (9d2b30dc3, already pushed, so recorded here rather than rewritten): it said the cross-check was clean on "all 183 real records". 183 is the active keyed-record count; the cross-check scans the record WINGS — 195 files at that commit, 190 of them carrying frontmatter. The check was clean; the figure named the wrong population.

timothyandClaude Opus 5	b24c51ab51	fix(688): stop enumerating multiplicities, pin n and the keyless filter, de-couple the vacuity floors ... Review round 5. One reviewer returned MERGEABLE with prose findings; the other found four more, two of them real test gaps. Both are addressed here. THE MULTIPLICITIES WERE WRONG AGAIN — fourth commit running. The "measured" sequence 59, 59, 60, 60 -> 81 is measured nowhere: origin/main has 59, 59, 59, 60, 60 and HEAD has four 59s and three 60s. I had even tagged it `(measured)` in a canonical decision record. So this stops enumerating them. All four sites now state only the load-bearing, stable fact: the lengths climb to the ceiling and then jump STRAIGHT to 81 with nothing in between, so one record moves p90 by 21 lines. The multiplicities change with every record added; the gap is the point. This is the same "fix the boundary, not the site" move the tests got three rounds ago, applied to prose that had failed four times. TEST GAPS - Deleting the over-tight test removed the only pin on CeilingCalibration.n: a mutation returning n=1 passed all 19 relevant tests while printing a wrong denominator in the drift notice. Pinned. - The `if r.key` filter was load-bearing in production and unpinned: main() passes the UNFILTERED list (194 entries, 11 keyless, one a 106-line "Records formerly in this file" scaffolding block), while every test handed the function a pre-filtered list — oracle and production agreed only by accident. Pinned. - The --record-ceiling 0 arm's claim that it "cannot go vacuous for any non-empty corpus" was FALSE: an empty record body is validator-valid and record_prose_lines returns 0, so a corpus of empty-bodied records has no offender at 0. Now -1, which makes the claim true. - The three `len(recs) > 100` vacuity floors were themselves growth-coupled — 83 legitimate retirements would red them even with the ceiling still calibrated, which is the #688 class in the guard rather than the assertion. Lowered to >20 where a floor is meaningful, and to plain non-empty on the derived-ceiling test, whose derivations need nothing more. - test_main_FEEDS_the_crosscheck now compares against `set(record_wing_files())` instead of a hardcoded basename, killing the same mutation with zero corpus dependence. PROSE - "ordinary growth cannot cross it — NOT immune" contradicted itself in four places. Now: no SINGLE ordinary addition can cross it; this is measured headroom, not immunity. - "trimming or archiving 15" blurred two different denominators. Trimming leaves 3/183 = 1.64%; archiving leaves 3/168 = 1.79% because the denominator moves too. Both verified, both under the floor, now stated separately. Verification: 431 scripts/tests pass; ruff at baseline parity (47 — a 121-char docstring line briefly took it to 48 and is rewrapped); validator exits 0 with no drift notice; corpus at p90=60, 18/183, calibrated; record still 60 lines.

timothyandClaude Opus 5	c56dfdd539	fix(688): delete the last over-tight test, pin the crosscheck's INPUT, fix 4 prose defects ... Review round 4, both reviewers. Both report the code path SOUND and the #688 coupling class analytically gone (rows proved, not merely observed green); one caught 28 of 30 mutations. What blocked was one over-tight test, two unpinned mutations, and prose — including two defects the PREVIOUS commit introduced while claiming to fix numbers. TESTS - Deleted test_adding_ordinary_records_cannot_RED_the_blocking_property. It appended two long records to the LIVE corpus and asserted flags_minority on the RESULT, so it crossed the cap two records before production does (56/221 vs 54/219) — a test named "cannot RED the blocking property" being a tighter tripwire than the property. Fourth instance of the #688 defect in this change. Deleted rather than tuned: both its jobs are already covered off live data (the synthetic v4/v5 contrast, and the deliberate live guard at the production threshold). - test_main_FEEDS_the_crosscheck_the_REAL_wing_files closes a mutation hole found by review: replacing `pyyaml_frontmatter_faults(record_wing_files())` with `...([])` in main() left the ENTIRE suite green. Both existing wiring tests monkeypatch the function, so they pinned that its RETURN reaches errs, never that its ARGUMENT is the corpus — the '#609 marker that printed OK while doing nothing' defect one level up, which is the exact thing the new record indicts. Verified: the mutation now fails this test. - test_main_actually_REPORTS_... went vacuous whenever the ceiling legitimately goes green (`False is False` passes with the whole warning branch deleted). Added an arm at --record-ceiling 0, which no non-empty corpus can make vacuous. - Pinned two surviving mutations: ceiling_calibration's n_over boundary (it recomputes the count, so oversized_records' exclusivity test does not cover it — `>` vs `>=` differs by the 3 records sitting exactly on the ceiling) and p95's quantile (the 95/5 fixture cannot tell 0.95 from 0.99). PROSE — two of these were introduced by the previous commit, whose stated job was fixing numbers. That is the pattern worth naming, not the individual typos. - "so ONE new record could move p90 lines" — the previous commit deleted the magnitude and left the sentence ungrammatical. Now "by 21 lines". - It also introduced a THIRD variant of the sequence it was correcting ("60, 60, 60") and missed a FOURTH site in ci-cd.md still saying "twenty lines". All four sites now read the measured 59, 59, 60, 60 -> 81, and 21 lines. - 59- and 60-line records were described as "above the ceiling"; they are at or below it. - "routine growth cannot cross it" overstated the bound: it is deliberately less sensitive, not immune. Reworded, and the THIRD and tightest arm is now documented wherever the other two appear: consolidating 15 of the 18 offenders drops below the 2% floor (verified: 3/183 = 1.64%). That is in real tension with test_oversized_records_can_go_green and is stated as accepted — at 3/183 the constant genuinely is mis-calibrated — with the remedy named: a consolidation PR that large should re-derive the ceiling in the same change. - Corrected a docstring that called the 999-ceiling failure "silently deleting the assertion"; it would go red, not silent. Verification: 430 scripts/tests pass; ruff at baseline parity (47); validator exits 0 with no drift notice; corpus at p90=60, 18/183, calibrated. The two new claims were measured, not assumed: the empty-list mutation fails the new test, and 15 consolidations reaches 1.64%.

timothyandClaude Opus 5	b3a8826281	fix(688): stop asserting live-corpus order statistics anywhere in the suite ... Review round 2 (both reviewers, independently) found the round-1 fix incomplete: the live-corpus coupling survived in two more tests. This is the THIRD instance of one defect class in this change, so the fix is to remove the coupling rather than patch another site. BLOCKER — test_adding_ordinary_records still asserted live order statistics. The `if before.marks_tail:` guard made the PRECONDITION conditional but left the CONCLUSION (`assert not after.marks_tail`) an assertion about the live p90. Verified: appending 16 ordinary 30-line records — nothing long, nothing unusual — makes both sides true and fires it, reddening the blocking job for an unrelated author. Exactly what #688 exists to abolish. The v4-vs-v5 contrast moved to test_v4_would_have_reddened_where_v5_holds, built on a distribution the test OWNS, reproducing the shape that matters (a sparse gap just above the ceiling). The real-corpus test now asserts only the robust claims: the additions were counted, v5 holds, and the measured headroom. Same treatment for the "bad ceiling" teeth test, which hard-coded that 200/229/230 stay rejected on the live corpus — three new 200+ line records flip it. Teeth now demonstrated synthetically; the only live-corpus assertion left is that today's ceiling is accepted, which needs 38 over-ceiling or 718 short additions to break. The IFF drift test could lose its quiet branch: one 61-line record makes BOTH the 60 and 999 ceilings drift, at which point an UNCONDITIONAL notice would pass. Both ceilings are now DERIVED — p90 itself (always calibrated, since p90 <= p90 <= p95) and max+1 (always off the tail) — so each branch is guaranteed by construction, and the test asserts it exercised both. Added the missing regression test for the typed-mapping-key TypeError: removing `key=str` now fails a test instead of only a manual probe. Corrected against measurement: the v5 row of the record's own version table still stated the REJECTED first-draft bound (`0 < f < 1/3`) — the canonical artefact contradicting both the code and its own next paragraph; accepted range is 43..180, not "roughly 45..150"; breaching the cap takes 38 additions, not 37 (37 lands exactly on 0.25, which passes under `<=`); "5x headroom below the floor" was inverted; ci-cd.md said four versions "all ratcheted" when v1 was vacuous and v2 accepted an absurd ceiling; and the crosscheck record overstated protection — script-tests is NOT a required check, so "no broken record has reached main" is procedural, not structural. Evidence the coupling is actually gone: mid-fix the corpus sat at marks_tail=False (an edit pushed this branch's own record to 61 lines, moving p90) and the suite stayed fully green. Under the old assertions that state reddened CI. The record is trimmed back to 60 so main ships calibrated and no drift notice nags. Verification: 428 scripts/tests pass; ruff at baseline parity (47); validator exits 0 with no drift notice; corpus at p90=60, 18/183 over the ceiling.

timothyandClaude Opus 5	80818aa294	fix(674,688): address independent review — restore the coarse bound's teeth ... Two independent cold reviews (one cross-family) agreed on the top two findings. 1. The #688 fix was defeated by its own complement test. test_main_is_QUIET_about_ drift asserted the drift notice was ABSENT while running main() over the LIVE corpus — whose failure condition is bit-for-bit v4's assertion, in the same blocking job, three functions down. p90 sat exactly on 60, so one over-ceiling record would have reddened it. Replaced with an IFF test that uses ceiling_calibration as its oracle, so it asserts the WIRING rather than the corpus's current state, plus a guard that at least one branch fires. 2. The coarse bound was nearly unfalsifiable. `0 < fraction_over < 1/3` accepted EVERY ceiling from 39 to 229 on the real corpus — including the ceiling of 200 my own docstring offered as the case it catches, because one 230-line record keeps the count nonzero. That claim was simply false and is corrected. The floor is now a FRACTION (2%) and the cap 25%, which rejects 200/229/230 and 20, and accepts roughly 45..150. Headroom measured, not estimated: 37 consecutive over-ceiling additions, against ONE record to break v4. 3. yaml.safe_load raises a bare ValueError, not a YAMLError, on a well-shaped but impossible date (stale-after: 2026-06-31), which escaped as a traceback and killed the validator on any machine with PyYAML. The except is now deliberately broad, with a test. 4. PyYAML returns TYPED mapping keys, so a stray `1: x` made sorted(set|set) raise TypeError. Sorted with key=str. 5. The headroom prose was arithmetically wrong (~42/~40 where the real values are 63/64; each addition moves numerator AND denominator) and the record counts were stale. Corrected against measurement. 6. test_adding_ordinary_records passed identically with its two additions removed. It now asserts the additions were counted, and that they break the v4 property while leaving v5 satisfied — guarded by `if`, never asserted, since whether v4 currently holds is a fact about the live distribution and asserting it would rebuild the ratchet. Also recorded honestly in docs.frontmatter-pyyaml-crosscheck: decisions-guard installs no PyYAML, so in CI the cross-check always skips and script-tests already caught both hazards — the CI delta is close to zero and the real fix is the local loop plus the tool/suite agreement. And the new record was trimmed 64 -> 58 prose lines: at 64 it moved p90 to 64 by itself, i.e. this PR would have reddened the old blocking job. That is now cited in the test as the live demonstration. Verification: 426 scripts/tests pass; ruff at baseline parity (47); validator exits 0; corpus back to p90=60, 18/183 over the ceiling, marks_tail and flags_minority both true.

Two defects in scripts/decisions_validate.py, fixed together because they share the validator and its pytest suite. #674 — the validator reported OK on frontmatter PyYAML rejects. The hand-rolled reader is deliberately dependency-free (decisions-guard and the Husky hooks install nothing), so it cannot see a bare apostrophe closing a single-quoted scalar. Hit twice in one session by two independent agents. `pyyaml_frontmatter_faults()` now cross-checks the parse against PyYAML whenever PyYAML is importable, and is SKIPPED with a ::notice:: when it is not — the read path stays dependency-free. The two known hazards fail differently and the fix covers both: the apostrophe makes PyYAML reject the document, while an unquoted ` #` parses fine and silently TRUNCATES the value. So the check compares parsed results key by key rather than try/except-ing the load, which is also what makes it generalize past the two known characters. PyYAML wrote these files, so on disagreement it is authoritative and the file is the defect. The comparison has one implementation, called by the validator and by the existing test_decisions_lib agreement test, so the tool and the suite cannot drift. #688 — test_real_corpus_ceiling_sits_at_the_TAIL_BOUNDARY asserted p90 <= 60 <= p95 in the BLOCKING script-tests job. p90 sat exactly on the ceiling and the distribution above it is sparse, so one ordinary record moved p90 by twenty lines and reddened CI for whoever wrote it; it reproduced twice live (#672, #706) and both times the only in-scope remedy was trimming the new record to fit the constant. v5 splits the claim by robustness instead of hunting for a better single assertion. The blocking test now asserts only the coarse, non-ratcheting property (the ceiling flags a nonempty proper minority, 0 < fraction_over < 1/3); the fine tail-boundary claim is measured every run and REPORTED as a ::notice::, on the same reasoning stale_records already uses — a constant going out of date is the passage of corpus growth, not a defect in the commit under test. The fine property is still asserted, against synthetic distributions the test owns. The ceiling stays 60. Verification: 424 scripts/tests pass; ruff at baseline parity (47 before and after); the cross-check is clean on all 183 real records; a positive control pins that record_wing_faults alone still reports both hazard files as clean, so the new red cannot pass for the wrong reason; and a test demonstrates that appending #672's 62-line and #687's 107-line records to the real corpus does not red the blocking property.

timothy	8f6d4f4432	fix(706,707,711): fence the review-verdict write on the timeline retarget count ... Three related defects in the `review-verdict/h10` gate, all surfaced by the cross-family review of PR #705. #706 race 1 — a stale run could overwrite a fresher verdict, permanently. The race was reproduced live rather than reasoned about (Gitea 1.25.4): with every other workflow stripped, probe PR #722 showed run 7520 (`opened`) finishing 20s AFTER run 7521 (`synchronize`) started. `pull_request_target` runs for one PR genuinely overlap, older finishing last. The issue proposed serializing with a non-cancelling concurrency group. That is REFUTED by measurement: with the group active, runs 7528/7529 still overlapped and 7528 ended 36s after 7529 began. A first probe appeared to show the group working — a negative control with no `concurrency:` key at all showed the same cancellations, revealing Gitea auto-cancels superseded `push` runs on its own and the probe had measured that, not the group. The auto-cancel does not extend to `pull_request_target`. The fix leaves the runs unserialized and instead makes an overtaken run decline to write: count `change_target_branch` events on the PR timeline at start and again just before the POST, and post nothing if the count moved. The COUNT is the key because the branch NAME is ABA-vulnerable (`main -> S -> main` reads `main` at both ends — how #698 route 1 forged its exemption). Abstaining is a handoff, not a stall: every retarget fires `edited`, so the event that makes a run abstain has already queued its successor. `updated_at` was rejected as the key precisely because it moves for comments/labels, which queue nothing. #706 race 2 — a human BLOCKED landing in the unclosable window between the pre-POST re-read and the POST was silently turned green. After an exemption `success` the job now re-reads the per-POST history and repairs its own status to `pending` if a human verdict appeared above a high-water mark taken just before the write. The repair is `pending`, never a copy of the human's state. The id comparison is load-bearing: a presence test would fire forever on a base-mismatched verdict and deadlock that PR's exemption. #707 — `pr-changed-files.sh` bound `.base.ref` and `.head.sha` across the enumeration but never `.base.sha`, so an ordinary advance of `main` mid-paging could drop a code path from an offset-paged diff and leave a complete-looking docs-only list. Now bound from the JSON already fetched (no new round trips). #711 — `.codex/` added to PROTECTED. It mirrors `.claude/hooks/` byte for byte, including the merge-consent hook, so the "a PR that can weaken the gate cannot exempt itself" rule had an incomplete path list. Latent today (untracked), live the moment anyone tracks it. Residuals are stated, not implied: a retarget inside the final round-trip, and the repair being itself a read-then-write. Gitea's status API has no compare-and-set, so neither reaches zero; both now fail toward `pending`. Tests: 398 pass in scripts/tests. Each new guard was mutation-checked — the fence's motion comparison, the untrusted-count gate, the repair POST and the id high-water mark were each neutered in turn and the intended test went red while its positive control stayed green. fixes #706 fixes #707 fixes #711 Decisions-Edit: yes	2026-08-03 21:41:16 +02:00

timothyandClaude Opus 5	d4c600149d	fix(698): review round 4 — the PROTECTED guard was DEAD; define before use, fail closed, fix prescriptive docs ... Round-3 cross-family review returned BLOCKED with 3 Mediums. The first was serious and self-inflicted. THE PROTECTED GUARD WAS A NO-OP. Round 3's `count_matching` / `count_not_matching` helpers were defined AFTER the classification chain that calls them, so `count_matching` was `command not found` on every run, `$( )` yielded an empty string, `[ "" -gt 0 ]` errored, and the `elif` was simply skipped — the protected-path check never executed at all. Confirmed by direct execution before fixing. Three "protected path" tests stayed GREEN throughout, because a protected path is also not a manifest and not docs-only, so the job still reached `pending` down a different route. Asserting the STATE could not distinguish a working guard from a dead one. The mutation battery missed it too: I had mutated the predicates, not their reachability. Fixed three ways: * helpers are defined immediately after `gh()`, before any use; * the three counts are evaluated ONCE at TOP LEVEL and validated numeric, because `exit 1` inside `$( )` leaves only the subshell and, with the substitution sitting in a conditional, `set -e` never fires either — so a grep error had been silently reading as "no match". A non-numeric result now aborts with nothing posted, and an absent required check blocks the merge; * the helpers return a non-numeric sentinel instead of trying to `exit`. Verified: an invalid regex now exits 2 and posts NOTHING (previously it classified and posted). Renaming the helper at its definition turns six tests red. TESTS, aimed at the failure mode rather than the symptom: * assert the DISCRIMINATOR (the job's `Decision:` reason line), not the outcome — when several branches yield the same verdict, the verdict cannot tell you which ran. A first draft of this test asserted the status description and failed against a WORKING guard, because for `pending` the description is constant; * a cheap stderr sweep for `command not found` / `integer expression expected` / `unbound variable` across four representative PR shapes. Each of those makes an `if` condition merely false while the job exits 0 and posts a plausible status, so this catches a whole family of silently-skipped guards. DOCS. The record and ci-cd.md still PRESCRIBED the here-string that round 3 removed — following them would have reintroduced the temp-storage failure. Both now prescribe counting, define-before-use, top-level evaluation and numeric validation. The workflow's measurement paragraph still said the npm manifests "are included" three lines above the note saying they are excluded; corrected. 379 tests pass.

timothyandClaude Opus 5	d8bd1dcba9	fix(698): review round 3 — count instead of matching, re-read before the POST, fix stale docs ... Round-2 cross-family review returned BLOCKED: 2 High + 3 Medium. HIGH — here-strings traded one fail-open for another. `grep -q… <<< "$data"` fixes the SIGPIPE inversion, but bash materialises a large here-string via temporary storage, so it fails when temp space is full or unwritable — and since these sit inside `if`/`!`, that failure flips the predicate exactly as SIGPIPE did. It did NOT reproduce on my bash 3.2, DID on the reviewer's Linux bash 5.x, and CI is Linux; the disagreement is itself the argument for a construct that cannot fail either way. Path predicates now COUNT with `grep -c`, which drains stdin (no early exit, no SIGPIPE) over an ordinary pipe (no temp file), and grep's status is read honestly: exit 1 means "zero matches", a legitimate answer, while >1 is a real error that FAILS THE JOB rather than silently reading as "no match". `set -e` does not catch these on its own — they sit in command substitution inside a conditional. Verified correct under 171KB input AND an unwritable TMPDIR. The description test became a `case` prefix match, removing another pipeline from a security predicate. New record `ci.grep-q-pipefail-inversion` covers the whole class. HIGH — a human verdict landing mid-run was still overwritten, and the code claimed otherwise. The job read statuses once, classified over several round-trips, then posted: a reviewer posting BLOCKED in between had it replaced by an exemption `success`, turning an explicit rejection into a merge. Added a re-read immediately before the POST which refuses to write over a human verdict found then. The heading no longer says "never overwrite" — it cannot promise that, since there is no compare-and-set on Gitea's status API. Remainder tracked as #706. MEDIUM — documentation was stale in three places, all mine. The record's frontmatter `rule:` still listed the npm manifests (I fixed the body and forgot the frontmatter, so the canonical rule AND the generated catalog were wrong); docs/ci-cd.md still said `edited` was absent from `types:`, contradicting a section I had just updated; and the workflow header still implied the `edited` re-run settles the ABA race. All corrected to say detection, not atomicity. TESTS. 373 pass. New: a mid-run human verdict via a status stub that returns nothing on the first read and BLOCKED on the re-read, and large-input regression tests for the ADVISORY hook, which had none — the copy with less authority is the one that quietly keeps a bug (#649's whole point). Mutation-verified: reverting the hook predicate, the workflow predicates, or the pre-POST re-read turns exactly the intended tests red while every positive control stays green.

timothyandClaude Opus 5	bafb487eaa	fix(698): review round 2 — close a PRE-EXISTING SIGPIPE inversion, narrow the bot allow-list, correct two overclaims ... Cross-family adversarial review returned BLOCKED with 3 Blockers + 2 Highs. Two were verified independently before acting on them. BLOCKER 1 (pre-existing on main, not introduced here). `producer | grep -q…` inverts under `set -o pipefail`: grep exits at its first match, the producer takes SIGPIPE and exits 141 once the list exceeds the pipe buffer, so a MATCH is reported as a FAILED pipeline. Reproduced at 1901 paths / ~171KB, inside the enumerator's 2000-file cap: * `A.cs` + 1900 docs paths -> docs_only=yes, status 141 (a C# PR exempted) * `.gitea/…` + 1900 docs -> the PROTECTED guard MISSES entirely The second reaches a green required status on a PR rewriting the gate, with no retarget, no bot account and no forged status. This construct shipped with the original docs-only check (review-verdict.yml:257 on main), so it was live. Fixed in both the enforced gate and the advisory hook by using here-strings, which have no writer to signal. New record `ci.grep-q-pipefail-inversion`. BLOCKER 2 (mine). `web/package.json` / `web/package-lock.json` are removed from BOT_MANIFESTS. renovate.json enables only nuget/github-actions/dockerfile, so npm is unmanaged here and the entry bought nothing — while package.json `scripts` are EXECUTED by CI (npm ci, npm run build). It widened an exemption onto a code-execution path for no benefit. BLOCKER 3 + HIGH (documentation was wrong, code unchanged). The claim that `edited` made the retarget residual "non-durable" is retracted: runs are not serialized, so a stale run can post `success` after the reclassifying run posts `pending`. The ABA transition is narrowed and observable, NOT closed. Likewise the provenance check asks "posted by a user credential", not "posted by a reviewer" — ETV_STATUS_AUTH is basic auth, so a #697 forgery gets a non-null creator AND an attacker-chosen description and is preserved as human. Both now stated at full strength. TESTS. 4 large-input cases crossing the pipe buffer, each paired with a large-input POSITIVE control so "large lists now fail closed" (a deadlock) cannot pass as a fix. Verified by mutation: reverting the here-strings turns all three negatives red while the control stays green. Two of my own weak tests fixed — the "base advances" case called head_moves_to(SHA) with the already-current sha (a duplicate positive control, now a structural assertion that the comparator is .base.ref and never .base.sha), and the arity test counted five arguments without checking the fifth was the base. The whole class was invisible because every previous test used a handful of short paths: a guard whose behaviour depends on a buffer threshold needs a test that crosses it.

timothyandClaude Opus 5	f523fc535d	fix(698): bind the base, constrain the bot exemption by content, re-derive unattributable successes ... The `review-verdict/h10` exemption path decided from mutable or unattributed PR state, and a machine-written `success` was never revalidated. Three routes, one root cause, so one change. Route 1 (reproduced live as probe PR #703, closed unmerged): `/pulls/{n}/files` diffs against the PR's LIVE base, so retargeting moves the answer without moving the head sha. A PR opened into `main` and retargeted mid-run enumerated docs-only and was granted `h10=success` while its diff against `main` carried a C# file; retargeting back reclassified nothing. `scripts/pr-changed-files.sh` now takes the expected base branch as a REQUIRED 5th argument (optional would be a silent opt-out) and checks it before and after paging; the workflow passes it from the `pull_request_target` payload, which a retarget cannot rewrite, and `edited` is in `types:` so a retarget reclassifies. A pinned two-sha diff would close route 1 outright but Gitea 1.25.4 cannot serve one: `compare/{base}...{head}` returns no `files`, and a `--depth=1` fetch of the two shas has no merge base. Measured, not assumed. The residual window is stated in the code and the record rather than papered over. Route 2: `pull_request.user.login` is the PR's immutable CREATOR while its head is not, so pushing code onto an open Renovate branch kept the exemption. The bot exemption now also requires EVERY path to be a dependency manifest — a set measured across all 11 Renovate PRs this repo has had, not guessed. Route 3: the never-overwrite short-circuit exited on ANY `success`, so a forgery obtained once was inherited forever. It now fires only for a status positively identified as a human verdict (non-null `.creator.login` AND a `Review-verdict:` description — measured: user-posted statuses carry a creator, Actions-posted ones carry null). Written in the positive direction so an unrecognised shape is re-derived rather than trusted. The two exemptions are composed, not chained: as an `elif` chain a Renovate docs-only PR lost the docs-only exemption. Caught before commit and pinned by a test. Tests: 17 new cases in scripts/tests/test_pr_changed_files.py, each verified by mutating the clause it covers (8 mutations, 8 kills). Both records trimmed under the 60-line prose ceiling so the corpus tail-boundary check stays calibrated. Does NOT close the class: anyone who can POST a status directly can still impersonate a verdict — that is #697, deliberately left open.

timothy	20b7171fba	fix(672): review round 2 -- correct a stale rule: field, document the self-test gap ... Re-review of the fix commits returned MERGEABLE (nine trigger mutations all caught, every prior finding verified against independent sources) with four low-severity findings. All four are addressed here. F1: `release.verdict-status-check`'s `rule:` frontmatter still said "A `pull_request` workflow auto-passes the two exempt classes". Round 1 past-tensed that record's BODY and left its `rule:` stale -- which is the exact failure mode the previous commit cites as the reason to put limitations in `rule:` in the first place. The catalog row mirrors this field verbatim and it mirrors again per-`key:` into MemPalace, so a stale `rule:` propagates further than a stale paragraph. F2: same record, "is what makes the rollout self-hosting" -> past tense. It described #630 and now reads as a live property. F3, the one that matters operationally: base resolution cuts BOTH ways. A change to `review-verdict.yml` is no longer exercised by its own PR -- the PR runs the version already on `main` -- so an edit goes live only ON MERGE, repo-wide, having never run. A broken edit merges green and then breaks the gate for every subsequent PR, and the PR that would repair it is gated by the same broken workflow. The recipe for verifying one safely (scratch base + throwaway PR + probe-named context) now lives in docs/ci-cd.md, which is where an operator looks, rather than in the record. F4: the sibling-workflow guard globbed `*.yml`, so a workflow added as `.yaml` would be silently unscanned. Latent today, which is when it is cheap. The record lost its meta-justification paragraph to the 60-line prose ceiling. Fifth trim this session; the operational recipe moving to ci-cd.md is better placement anyway, but it was forced rather than chosen. ersatztv#688.

timothy	b2a5c72bfe	docs(672): widen the residual to the real inventory (#697, #698) ... Cross-family review established the residual is materially larger than the previous commit said, and that saying "docker-build.yml / ETV_STATUS_AUTH" understates it. Gitea injects `GITEA_TOKEN` into EVERY job automatically, defaulting to read/write. So the set of workflows that can POST `review-verdict/h10` is not a short list to audit -- it is all of them, plus `workflow_dispatch` (1.24+ loads the definition from the selected branch) and `push`-triggered ones. A collaborator's own write-scoped API token is a route with no workflow at all, because branch protection binds the required CONTEXT, not its issuer. Recorded in #697. The same review found three defects in the exemption path itself, none of them introduced here and none closed here: a retarget race that enumerates a docs-only diff against a scratch base while the enumerator revalidates only head.sha, a Renovate-PR hijack (the exemption reads the immutable PR creator, not who pushed the head), and an inherited `success` that short-circuits before any PR/base/author/file check. Filed together as #698, since they share one root cause -- the gate trusts state it cannot attribute. Also drops the claim that the three properties are "pinned by tests". The tests pin the workflow's SHAPE; no in-repository test can establish status-authority isolation, and the sibling-workflow guard added in the previous commit catches only a workflow that names the context in plain text. Trimmed to the 60-line prose ceiling for the third time in this session. That is ersatztv#688 -- the ceiling is now deleting rationale two reviewers asked for.

timothy	35a8ea8aef	fix(672): review round 1 -- pin the trigger set exactly, sweep the stale claims ... Cold review found the first cut of the test satisfiable by a still-vulnerable config, and two prose claims that outran the evidence. The test asserted "pull_request_target present, pull_request absent". Adding `workflow_dispatch:` or `push:` ALONGSIDE it kept that green, and both are ref-resolved with secrets, so either one restores an equivalent self-supplied-definition path. Enumerating those two would have the same hole one trigger later, so the assertion now pins the whole set: exactly {pull_request_target}, nothing else. Verified by mutation -- adding `workflow_dispatch` now reds. Adds the guard that would have caught the residual below rather than only the instance: no workflow OTHER than review-verdict.yml may reference `review-verdict/h10` in executable lines. Scoped honestly in its docstring as a drift guard, not a security boundary -- a workflow can still write the status through an indirection a text scan cannot see. `release.verdict-status-check` item 4 still asserted, in the present tense, that a PR editing review-verdict.yml is judged by its own edited copy. That is now false for this workflow, and it is the record a reader resolving the gate from the catalog actually lands on. Past-tensed, with the surviving residual named. The probe count said three. There were four; the omitted one is the only one with a negative result, which is what turns an honest partial into an overclaim. Corrected in both the record and ci-cd.md, along with what was NOT measured (`reopened`/`ready_for_review` firing under the new trigger). Also records two operational consequences a maintainer will otherwise hit cold: retargeting a PR onto `main` leaves it statusless until its next push (`edited` is not in `types:`), and the required contexts carry a literal `(pull_request)` suffix, so repeating this fix on docker-build.yml would rename them and deadlock merges unless branch protection is edited in the same operation. Trimmed the record back under the 60-line prose ceiling -- for the second time this session, which is ersatztv#688 reproducing, not a defect here.

timothy	8b73234d78	docs(672): record that the fix closes the route, not the class (#697) ... Probing rather than reasoning turned up a second instance of the same vulnerability class while this fix was in review. `docker-build.yml` also triggers on `pull_request`, so it is head-resolved too, and it carries `ETV_STATUS_AUTH` (`REGISTRY_USER:REGISTRY_PASSWORD`) for the #420 revalidation read. Basic auth is not scoped: an account that can read commit statuses can write them. Confirmed with a scratch PR that POSTed a probe-named context using those credentials and succeeded — so a PR rewriting `docker-build.yml` can still post `review-verdict/h10=success` for its own head. That workflow cannot take the same fix. It builds and tests the PR's code, so it must resolve from the head; `pull_request_target` there would be the real footgun. It needs a read-only status identity instead. Filed as #697. The `rule:` field carries the limitation, not just the body, because the predecessor record's documented failure was exactly a reassuring sentence in the position a catalog reader stops at. Also trims the record to the 60-line prose ceiling. Adding it at 62 lines pushed p90 past the ceiling and reddened the blocking `script-tests` job — which is ersatztv#688 reproducing live, not a defect in this change.

timothy	cf907f0988	fix(672): trigger the verdict gate on pull_request_target scoped to main ... `review-verdict.yml` writes `review-verdict/h10`, the status branch protection requires on `main`. It triggered on `pull_request`, and Gitea resolves a `pull_request` workflow DEFINITION from the PR's own head commit — so a PR editing this file ran its own rewritten copy and could post `h10=success` for itself. `PROTECTED` did not help (the rewrite defines it too), and neither did branch protection, which requires the context rather than an author and carries `required_approvals: 0`. The #649 base-ref checkout binds the SCRIPTS this job runs to the base. It cannot bind the job definition. Only the trigger can. Measured on this instance (Gitea 1.25.4) with three throwaway scratch PRs rather than inferred from GitHub, since the premise is a claim about someone else's software: A. A PR rewriting the workflow posted its own probe context and the real `review-verdict/h10` was never written — the base definition never ran. B. Under `pull_request_target` the identical rewrite was ignored: the BASE definition ran and posted `h10=pending`, on `opened` and `synchronize` alike, with `secrets` still available. C. With `branches: [main]`, a PR into a non-main base produced no run and no status at all. The probes only ever posted probe-named contexts, never a forged `h10`. `branches: [main]` is half the fix, not a refinement: base resolution means the BASE branch supplies the definition, so without it the rewrite simply moves to an attacker-pushed base — and a status forged there is inherited by any later real PR with the same head sha (#663). `pull_request_target` is safe here only because this job never checks out or executes head-supplied code; the base-ref checkout is what makes the trigger usable, so the two are one decision. Rejected `required_approvals: 1` as the cheaper fix: Gitea forbids approving your own PR and this is effectively a single-maintainer repo, so it would deadlock every PR rather than gate the dangerous ones. Three mutations confirm the new test discriminates rather than merely passing: reverting to `pull_request`, dropping the `branches` filter, and re-adding `pull_request` alongside the safe trigger each go red with a distinct message. It parses the YAML instead of substring-matching because `pull_request` is a prefix of `pull_request_target`. Refs: #672 Decisions-Edit: yes	2026-07-28 21:28:38 +02:00

timothy	00e623c066	fix(632): bind a review verdict to its BASE branch, not only to its head sha ... #622 made `review-verdict/h10` a per-sha required status, so a new commit cannot inherit an old verdict — the required context is simply absent on the new head. Retargeting a PR's base reaches the same end from the opposite direction: the head sha and the status both hold still while the merge-base, and therefore the effective diff the verdict was formed against, changes underneath them. #622's record claimed the invariant holds "by construction"; this was the documented exception, and an unrecorded exception is how a guarantee degrades into a habit. `post-review-verdict.sh` now records the base branch in the status description as a trailing `(base: <ref>)`, and refuses to write a status at all if the base moved between reading the PR and posting — the same TOCTOU window the head check already covers, which the head check cannot see because retargeting does not move the head. `pretooluse-merge-consent.sh` reads the field back and denies when it no longer matches the PR's live `base.ref`. Two choices are load-bearing, and each is pinned by a test rather than left to a comment: - The comparator is `base.ref`, NOT `base.sha`. `base.sha` tracks the base branch's tip, which moves whenever anything merges to `main` — comparing it would invalidate every open verdict on every unrelated merge, converting a rare-event guard into a permanent merge deadlock. A base that merely advances is out of scope by design: rebasing onto it moves the head sha, which the per-sha binding already covers. - The field goes in the status DESCRIPTION, not the verdict comment. The comment body is parsed by `scripts/check-review-verdict.sh`, whose grammar had three false-opens in its history (#629); nothing parses the description, so this adds a field without reopening that surface. Scope is stated honestly rather than overclaimed: this is DETECTION on the hook path only. A commit status carries no base of its own, so the server-side required check cannot see a retarget, and a merge driven through the Gitea UI or API is unaffected. That is the accepted exposure — base changes are rare, manual, and this is a two-account repo — but it now fails loud in the one place that evaluates consent, instead of living only in a doc. Verdicts posted before this change carry no `(base: …)` and get NO opinion rather than a deny; denying would block every in-flight PR the day it lands, and the window closes on its own since verdicts are per-head and short-lived. Verified by mutation, six mutants, each killed by its intended test: remove the hook's deny; compare base.sha instead of base.ref; drop graceful adoption; stop recording the base; drop the TOCTOU guard; accept a PR with no resolvable base. The positive controls matter more than usual here — the test PR is deliberately non-docs (a docs-only PR short-circuits the whole gate and would never reach the base check) and the rest of the gate is unstubbed, so "the hook denied" alone proves nothing.

timothy	9114a7e8af	fix(649): point the ENFORCED review-verdict gate at the shared PR-file enumeration ... #658 landed the shared implementation, `scripts/pr-changed-files.sh`, and rewired the ADVISORY hook onto it. The ENFORCED copy — the one that writes the branch-protection- required `review-verdict/h10` status — was left byte-identical to main, so its fail-closed behaviour on a malformed or empty response stayed INCIDENTAL: an empty `n` erroring `[ "$n" -lt 50 ]` to false. That is #649's second Done-when box, and the whole point of the issue was that the gate with real authority was weaker than the gate with none. `review-verdict.yml` now: - checks out the PR's BASE ref (`base.sha`, `persist-credentials: false`), never the head, so a PR cannot supply the code that judges it; - runs `scripts/jq-preflight.sh` in FLOOR-ONLY mode — `--expect` here would deadlock every merge on `main` the day the runner's jq changes; - calls `scripts/pr-changed-files.sh` and reads its EXIT STATUS, never its stdout on a failure path. The env trap flagged in review is handled: the script reads GITEA_BASE_URL and takes owner/repo as two separate arguments, so passing BASE_URL and a combined `owner/repo` would have silently fallen back to the hardcoded LAN default. The ~40 lines of inline enumeration are deleted, so the two copies can no longer drift. A base ref predating #658 has no such script; that posts `pending` with the reason rather than dying with no status at all. The drift guard is re-tightened from "the hook uses the shared script" to "BOTH callers do", and the workflow's own preconditions are pinned by parsing the YAML rather than substring-matching it — `head.sha` for `base.sha` is a nine-character diff. Verified by mutation, six mutants, each killed by its intended test: ignore the exit status; check out the head; drop `persist-credentials`; add `--expect`; re-inline a `pulls/N/files?` fetch; delete the PROTECTED clause. That last one initially MISSED, and the miss was the useful finding. The test used a docs-only-plus-protected file list and passed with the clause deleted, because PROTECTED (`.claude/ .gitea/ .husky/ scripts/ docker/ci/`) and DOCS_ONLY (`docs/`, root `*.md`) are disjoint — on the docs-only path that clause can never fire, and DOCS_ONLY was doing all the work. PROTECTED is load-bearing only on the BOT path, so the test now covers a Renovate PR editing the shared script, with a positive control proving the bot exemption fires at all. The caller contract is tested by EXECUTING the workflow's `run:` block against a stubbed enumeration that fails while emitting a perfectly docs-only list — the one combination the "every failure path also happens to print nothing" redundancy cannot absorb, and the exact mutation that survived the whole suite last round. Docs: both "Landing note" blocks removed, and the record's base-ref paragraph converted from a future-tense requirement to present-tense fact with its staging rationale kept as history.

timothy	2c10f057b8	fix(648,649): stage the enforced-gate wiring behind the scripts it calls ... Splits the review-verdict.yml rewiring out of this PR. That workflow checks out the PR's BASE ref — deliberately, so a PR cannot rewrite the gate that judges it — and the base is main, which does not yet contain scripts/pr-changed-files.sh or scripts/jq-preflight.sh. Wiring it here would make the job exit 127 on its own PR and block the merge gate through the combined status, which reads red jobs as blocking. So this PR lands the scripts, their tests, the hook rewiring and the script-tests jq pin; the follow-up points review-verdict.yml at them once they exist on main. The two tests that asserted on review-verdict.yml are scoped accordingly, each carrying the reason. test_review_verdict_never_pins_a_jq_version is asserted NOW rather than in the follow-up, so the no-pin constraint on the required check is already enforced when the wiring lands.

timothy	63fa81fbb5	docs(648,649): the jq contract + the shared PR-file enumeration record ... Adds docs/ci-cd.md "The jq contract" (1.6 floor, the three divergent constructs, and the deliberate pin-vs-floor asymmetry with its merge-deadlock reason), plus two decision records: ci.jq-version-contract and ci.shared-pr-file-enumeration. ci.script-tests-job stops restating the three jq rules and points at the new record. Also corrects the script-tests preflight description: it is now two steps (git presence, then jq VERSION via scripts/jq-preflight.sh --expect 1.6), not one. A literal NUL byte had crept into the ci-cd.md paragraph describing jq 1.6's NUL truncation — which git treats as a binary file. Replaced with the literal text.

timothyandClaude Opus 5	fefd11dffe	fix(620): signal corpus size per RECORD; the aggregate becomes an unthresholded trend ... Squashed from 7 commits (4 review rounds) to keep the rebase onto #621 tractable; the full round-by-round history is on PR #642. corpus was 5658/5600 — over budget and warning again — 3h35m after #619 put it at 5228, with nobody consolidating anything. So this does NOT re-baseline. An aggregate over a monotonically growing corpus can only ratchet; that is the "permanently red, therefore no signal" state #542 re-baselined away from, and growth is not even a smooth rate to plan against (the corpus FELL from 5089 to 5042 across four days, then gained 427 in one evening as two large records landed). Replaces it with a per-record prose ceiling (default 60), non-blocking, naming each record over it — not monotonic, so it can go red AND green, and it points at a file. The aggregate is still printed as an unthresholded trend notice, with record prose and non-record scaffolding reported separately because they are not the same unit. The GENERATED catalog is no longer counted at all: it gains one row per record and no consolidation can shrink it, which made the metric partly a record COUNT in a line-count costume. The calibration test took FOUR versions, and the failures are the durable lesson: v1 true by construction (`max(under) <= 60 < min(over)` over lists built by that test) v2 a gap WIDTH — a ceiling of 200 also sits in a wide gap, so it passed v3 fraction band + "clear air" vs the nearest record above — hostage to an unrelated record: one ordinary 62-line addition reddened it with the ceiling correctly placed, and the only remedy was to RAISE the ceiling. That is this very treadmill, as a hard failure in what #631 makes a blocking job. v4 `p90 <= ceiling <= p95` — the property stated directly and scale-free. Two rules recorded: a guard test must depend only on the thing it guards, and a threshold over a growing population must be expressed in that population's own terms. Candidates: all over-ceiling records assessed, each actioned or declined with a reason. The largest (scan.libraryfolder-unique-identity, 230 lines) is a legitimate DECLINE — a dozen-odd distinct traps whose only copy that is. Nothing pruned, so no archive or supersession was required. An automated redundancy metric is explicitly rejected. Also: `--budget` is accepted but announces its retirement rather than no-opping silently; the dead `budget_ok` parameter is gone; and five "untresholded" typos are fixed, one of which was propagating into the generated catalog row and MemPalace's per-key drawer.

timothyandClaude Opus 5	f4473926d4	fix(643): close the status-string dodge, pin the allow-list anchors, fix two doc claims ... Round-3 review (MERGEABLE, all findings Low/Nit) — applied anyway, because each is the over-claim or unpinned-anchor family this PR keeps hitting. LOW — the `renamed => previous_filename REQUIRED` clause matched `.status` by exact lowercase string, so any other value took the `else true` branch: a row with `"Renamed"`, or with no status at all, validated fine and silently dropped its SOURCE path, letting `git mv ErsatzTV/Program.cs -> docs/a.md` read as docs-only. `.status` is now checked against a closed set and an unknown value fails closed. Two things that fix taught me, both caught by my own positive control rather than by review: 1. The first predicate was WRONG in a way that gated everything: inside `[...] | index(.status)`, jq's `.` is the ARRAY, so `.status` was null and every row failed. `$s` is now bound from the row before the context switches. A security check that rejects everything looks identical to a working one from the failing side — only test_gitea_real_status_values_are_accepted caught it. 2. The set includes BOTH `changed` and `modified`. Live Gitea 1.25.4 emits `changed`, but a closed allow-list built from the wrong vocabulary is worse than the hole it closes: it would gate every genuine docs-only PR. The property wanted is "reject what we don't recognise", not "enumerate one version exactly". LOW — three allow-list anchors had no test at all: dropping `^` from the `docs/` alternative (`ErsatzTV/docs/Program.cs` would exempt), dropping `$` from `.md` (`x.md.cs` would exempt), and dropping the non-empty-list guard. Since the round-3 `..` finding WAS an anchor subversion, they are now pinned; all three mutation-verified. NIT — docs/ci-cd.md called this job "a checkout plus a pure-stdlib pytest run", which the same file contradicts 450 lines later and which this PR's own record names as the bug that turned the job red on its first CI run. Also replaced a frozen "111 tests" with an explicitly indicative figure — the suite is ~190 after rebasing onto main, and a frozen count has rotted four times this session. 198 passed under both jq 1.8.2 and jq 1.6.

timothy	73577f484f	ci(631): install pyyaml too — the suite is not pure-stdlib, and CI proved it ... First CI run went red on `ModuleNotFoundError: No module named 'yaml'` at collection: test_migration_equivalence.py imports scripts/migrate_decisions_split.py, which uses PyYAML by design. It passed locally only because this machine already had PyYAML. The original claim came from reading decisions_lib/decisions_validate/build_catalog and the test files themselves — which is precisely the set that does NOT import yaml. Replaced with an AST import scan over all of scripts/, which gives the complete third-party set: pytest and yaml. (etv_client is imported only by scripts/scripted-schedules/entrypoint.py, a container entrypoint pytest never collects.) This does not contradict the dependency-free decisions READ path: decisions_lib._read_frontmatter is hand-written exactly so validation runs where nothing is installed. The one-shot WRITE path is allowed PyYAML, and its test needs it. Verified the way it should have been the first time: a clean venv with pytest alone reproduces CI's collection error; adding pyyaml gives 111 passed. Comments, ci-cd.md and the decision record all corrected to drop the "pure stdlib" claim. Refs #631	2026-07-26 13:24:19 +02:00
timothy	c0f4a52d7a	ci(631): preflight jq/git in script-tests, and reflow the header comment ... test_post_review_verdict.py and test_merge_consent_exemption.py exec the real post-review-verdict.sh and pretooluse-merge-consent.sh, which shell out to jq ~26 times. Those tests shim `curl` on PATH but NOT `jq`, and no existing small-lane job proves jq is present on that image — so a missing jq would land as ~20 opaque assertion failures rather than a diagnosis. Checks rather than installs: #390 deliberately removed run-time apt-get from CI, so the correct fix for a genuine miss is baking the tool into the runner image, and the error message says so.

timothy	69d8d3ccfe	ci(631): run scripts/tests in CI as its own job, not inside the flake-covered decisions-guard ... Nothing executed scripts/tests/. No workflow and no Husky hook invoked pytest: decisions-guard runs decisions_validate.py and build_decisions_catalog.py directly (the code, never its tests) and the `test` job is dotnet test only. The 111 tests guarding the decision corpus, the #610 migration-equivalence harness, the merge-consent exemption logic and the #622 review-verdict poster were enforced only by whoever remembered to run pytest locally. Adds a `script-tests` job to pr-checks.yml rather than the step inside decisions-guard the issue proposed. decisions-guard is covered by ci.decisions-lifecycle-flake, a standing instruction that a lone `decisions lifecycle` red is a known flake and must not be investigated — so a genuine pytest regression there would surface as exactly the red every session is told to wave through. A gate inherits the credibility of the job it lives in. Runs unconditionally: the suite executes the real post-review-verdict.sh and pretooluse-merge-consent.sh, so a `scripts/**` path filter would miss a .claude/hooks/** edit. ~10s, pure stdlib + pytest. Negative control verified locally (broken test -> exit 1); CI-red measurement follows on a scratch PR per the Done-when. Refs #631	2026-07-26 13:24:19 +02:00
timothy	3d720a6bc1	fix(621): exempt by exact path, not basename — my "no basename exemption" claim was false ... Re-review found the basename exemption was not actually removed: the code still dropped any wing-root README.md, and the docstring defended that with "no such file exists today; the catalog README lives in TOPIC_DIR". That is false — docs/decisions/archive/ README.md exists and parses to []. So the rule text in the record, the catalog row and ci-cd.md all asserted something the shipped code contradicted. It was also a live hole, not just wrong prose: dl.active_files() globs RECORDS_DIR.rglob with NO filter, so a future docs/decisions/records/README.md would be a corpus source while exempt from the guard — verbatim the hole this PR cites as the reason to stop using _NON_DECISION_FILES, reintroduced one directory over. Now exempt by exact RELATIVE PATH ({archive/README.md}), with a test pinning that the same basename in the ACTIVE wing is still faulted. Mutation-verified. DISAGREEING with one review finding, deliberately. It asked for the empty-wing anti-vacuity check to be symmetric across both wings. The semantics differ: zero ACTIVE records means the scan measured nothing and any clean result is vacuous, while zero ARCHIVED records is a normal state — nothing superseded yet, true of any young repo and every fresh clone before the first supersession. Making it symmetric fails a correct corpus (it reddened 7 tests). The asymmetry stays, with the reason in the code and a test pinning it so nobody "fixes" it back. 127 passed.

timothy	98b3e8715b	fix(621): close three exemption holes and pin the guard's own wiring, per cold review ... An independent cold-context review found the guard could be disabled or bypassed in four ways, one of them silently. HIGH — the guard's only wiring was untested. Deleting `wing_faults=record_wing_faults()` from main() left the ENTIRE suite green (120 passed) while a real block-scalar record vanished again with `decisions-validate: OK`. Every existing test either called the collector directly or handed validate() a hand-built list, so nothing pinned that main() ever invokes it — the #609 "prints OK while doing nothing" defect, one level up, inside the fix for that same defect. Independently reproduced before fixing. Now pinned by a monkeypatched sentinel test. MEDIUM — a record could escape by BASENAME. `_NON_DECISION_FILES` is a set of TOPIC-dir names ({README, migration-map, retrieval-eval}) and was applied to the wings too, so a genuine record at records/docs/retrieval-eval.md was skipped. Not hypothetical: the path<->key rule forces key `docs.retrieval-eval` to that exact filename, and dl.active_files() applies that filter only to the TOPIC_DIR glob — so the file would be a corpus source while exempt from the guard. Now nothing is exempt by basename. MEDIUM — the archive exemption was by LOCATION but justified by IDENTITY. Anything directly in archive/ was skipped, so a new unparseable archive/foo.md would vanish in the one directory left unwatched. Now exempt only if it really is a #610 stripped index: one keyless record with a known generated heading. LOW — parse-to-WRONG. `rule: >-` with an UNINDENTED continuation containing a colon parses to one VALID keyed record whose rule is literally ">-", plus a junk key, silently truncating the real value. PyYAML rejects that input, so the hand reader is more permissive than the writer. Now faulted via an unknown-frontmatter-key check. LOW — an absent or empty wing reported clean. Now loud: refusing to certify a corpus from a scan of nothing. Doc corrections, all measured rather than asserted: "all 167 records use single quoted lines" was false (117 of 168 rule: values are unquoted plain scalars — the invariant is single-LINE); the archive shape in the record, ci-cd.md and the rule: field said `archive/<area>/` where the code deliberately uses archive/** ; the mutation count is 10, not five; and the "converts ANY reader limitation" claim is softened to the class it actually covers. 125 passed.

timothy	0f565b1f7e	fix(621): make an unparseable decision record loud instead of silently invisible ... A file under the record wings that the dependency-free frontmatter reader cannot parse returned [] and simply vanished from the corpus: decisions_validate.py printed OK, build_decisions_catalog.py --check said "up to date", the record was absent, and nothing anywhere errored. Reproduced end-to-end with a YAML block scalar (`rule: >-`), which is the natural thing to reach for on this corpus's very long rule: values and which parsed fine under PyYAML before #610's dependency-free reader. An EXISTING record disappearing was already loud (the no-vanish diff check). The hole was a NEWLY ADDED record, which that check structurally cannot see — no base state to diff against — so the author's own PR looks clean. Hence a per-PATH check, not a per-construct or diff-driven one: asserting "this path yields exactly one keyed record" turns any present or future reader limitation from silent to loud in one move. Adds record_wing_files/record_wing_faults to decisions_validate.py, surfaced through validate() as ERRORS (a file in the record wings that is not a record is a mistake by definition) and reported first, since a file that failed to parse leaves every downstream check silently evaluating an incomplete corpus. The five top-level stripped legacy archive files are exempt — they are generated "Records formerly in this file" indexes, keyless by construction, and are what keeps older date-based pointers resolvable. _read_frontmatter is deliberately NOT extended to accept block scalars; rationale in the new docs.record-wing-parse-guard record. 8 tests, mutation-verified: with the check neutered 5 go red, restored all 119 pass. A live-corpus positive control asserts the wings are non-empty so a clean result can never be vacuous. Refs #621	2026-07-26 12:03:43 +02:00
timothy	628ae46f7f	fix(622): bind H10 merge consent to the reviewed sha via a required commit status ... `pretooluse-merge-consent.sh` proves all three consent conditions at the moment the merge tool is called. With `merge_when_checks_succeed=true`, condition (a) is delegated to Gitea, which then merges whatever head is green at ITS merge time — while (b) Done-when and (c) the head-referencing verdict were proven against the head at SCHEDULING time. Every commit pushed in between merges unreviewed. The gate is not bypassed; it is satisfied against a snapshot that stops being true. Demonstrated as a controlled A/B rather than inferred, with a CI check left pending so Gitea waits as it really does: without a required verdict context: unreviewed commit B MERGED with it: same sequence REFUSED after reviewing B and posting it: merges — blocked, not deadlocked NOTE the anecdote in #622 is wrong and is corrected in the docs rather than repeated: PR #619 does carry `Review-verdict: MERGEABLE @ 02c82b35`, posted six seconds before the merge, explicitly re-reviewing the follow-up commits. #622 was filed off a lagging API read. The hole is real regardless, and structural — nothing FORCED that re-review inside the window Gitea would have merged in. This turns a property that held by diligence into one that holds by construction. The fix is the sha, not a smarter check. A Gitea commit status belongs to exactly one commit, so a status written for a parent cannot be inherited by a child that did not exist yet. `review-verdict/h10` becomes a REQUIRED status check on main: push a new head and the context is simply absent, which Gitea reads as not-passing (verified against 1.25.4: missing AND pending both block, and auto-merge re-checks the current head). It also covers merge paths the hook never sees — Gitea UI, raw API, another agent's session. - scripts/post-review-verdict.sh writes the comment and the status together so they cannot drift, and re-reads head after commenting: if a commit landed mid-flight it writes NO status and exits non-zero rather than retargeting the verdict at a commit nobody read. - .gitea/workflows/review-verdict.yml auto-passes the two exempt classes that would otherwise deadlock — Renovate-authored (platformAutomerge) and docs-only — and marks everything else pending. Exemptions are void when the PR touches .claude/, .gitea/, .husky/, scripts/ or docker/ci/. - The hook refuses to SCHEDULE an auto-merge unless that status is green on head, and no longer claims "CI green" on the mwcs path, where it never read CI. Two silent false negatives in the exemption path, both found by verifying rather than reasoning, both fixed at BOTH call sites (workflow and the hook's pre-existing docs-only carve-out): - The files endpoint caps at 50 rows and IGNORES a larger `limit` — PR #619 has 194 changed files and `?limit=100` returns 50. A single page saw ZERO protected paths there where the full enumeration finds ten. Both now page to exhaustion and withhold the exemption if they cannot complete. - A rename is ONE row whose `filename` is the destination, the source only in `previous_filename`. Verified live: `.gitea/workflows/renovate.yml` -> `docs/innocuous-note.md` presented as docs-only with no protected path visible. Both now read BOTH sides. Limits are documented, not papered over: base changes leave the head sha (and so the verdict) unchanged, and a PR editing the workflow is judged by its own edited copy — so PROTECTED is a guardrail against accident, not a tamper-proof control. fixes #622	2026-07-25 21:51:02 +02:00

The rationale-edit exemption was a substring test over the whole commit range, so any message containing the literal marker armed it -- including prose explaining why no marker was needed, which is how it fired live in PR #605: a green --base/--head run that was vacuous on the body-diff dimension, in the one PR that hand-resolved a merge conflict inside the corpus the guard exists to police. Now read as an affirmative `Decisions-Edit:` git trailer. Git parses trailers only in the final paragraph, so a quoted example message cannot arm it -- which matters because this commit and its decision record both quote one. A non-affirmative value (`no`) does not arm it either; the retired substring arms nothing and gets a ::warning:: nudge.

timothy	5dd0b147e8	docs(445): record that rebasing invalidates the CI toolchain image pin ... Hit this for real on this branch. `ci-image-pin` went red after a rebase that was otherwise clean, and the failure is confusing on three counts: - the pin must equal the short sha of the commit that touched docker/ci, and a rebase REWRITES that sha (e9fd26f6 -> 9130274c here); - the pin still resolves to a real commit and the tagged image still exists in the registry, so nothing looks broken; - the force-push does NOT republish: ci-image.yml filters on `paths: docker/ci/**`, and a rebase that leaves the Dockerfile's content unchanged produces no diff for that path. And it cannot be fixed by re-dispatching ci-image.yml, because that tags `git rev-parse --short HEAD` — the branch HEAD, not the commit that touched docker/ci. The two coincide only when the docker/ci commit IS HEAD, which is why the original two-step worked and the post-rebase state does not. Recorded in docs/ci-cd.md with the recovery, plus the cheaper lesson: land a toolchain-image change on its OWN branch first, so the consuming branch never carries the docker/ci commit through a rebase. This commit is also the recovery itself — it touches docker/ci, so it becomes the commit ci-image.yml tags, restoring the pin dance. Refs #445	2026-07-25 14:04:52 +02:00
