timothyandClaude Opus 5	168fe21088	fix(849): round 3 — replace every unknown state, and prove the clauses that claim to ... Two more cold reviews — cross-family (Codex/GPT-5.6) and a cold Claude reviewer that ran the mutants itself — converged on two separate things: a remaining class of paths that still left an unknown state standing, and, more importantly, that several clauses this branch claimed as fixes SURVIVED mutation of the exact text they name. ## Behaviour 1. The reconciliation witness matches the CURRENT row's `id`, not merely a row with the sentinel's description. Description alone is satisfied by an OLDER identical sentinel — which is what a fixed point produces — so a read carrying only the earlier row cleared the sentinel while the verdict buried under the current one ended up below the fresh mark. Falls back to the description where the server omits `id`. 2. The two OBSERVED-mutation arms mark a head that carries a row this run declined, instead of only abstaining. They are still right not to post their CLASSIFICATION — computed against a base or head the PR may no longer have — but a declined row must not stay authoritative for the whole window until a successor finishes, and for a PR's FIRST push no successor is queued at all. Scoped to `pre_state` being non-empty, so the common path stays quiet. 3. `replace_unknown_state` RETURNS a status. Its first version ended the failure arm with a successful `echo`, so it reported 0 after both POSTs failed and the fence caller's `exit 0` reported an abstention that had not happened. 4. An `id` difference counts only when BOTH reads supplied one. A response that omits `id` beside one that includes it otherwise reads as a replacement, and this guard's reaction is to abstain — over a row the classification had already declined. 5. Every element and every consumed field of the combined response is type-checked before extraction, and a schema failure routes to the replacement. `.statuses` being an array was checked; its ELEMENTS were not, so one scalar made `select(.context == $c)` hard-error and `set -e` took the step down before any path could mark the head. 6. The path-predicate failure replaces rather than merely exiting, for the same reason. 7. `$UNVERIFIED_DESC` says "Status write", not "Exemption write". It is now written on paths that grant no exemption at all, and it is the operator-facing text of a required check. 8. The no-op-repair skip keeps the human `::error::`. Skipping the WRITE is right — the head already carries the strongest marker — but that message is the only place a reviewer is told their verdict was buried. `raced_why` is a sentence now, not the token `human`. ## Proof The cold reviewer measured three of the six round-2 claims surviving mutation of their own clause, one against the verbatim predecessor from the previous commit. Nine proofs added: the no-mark downgrade's SCOPE (not just the description it writes), the page-2 refusals, the untrusted-fence write, the row-`id` comparison, the repair floor, the no-op skip, both `$own` exclusions, the write-result return, and the both-ids-present rule. Two of those needed the test double to grow: the combined-status stub emitted no `id` at all, so the `ex_id` clause had never once run with a non-empty value; and POSTs always succeeded, so both write helpers' failure arms were unreachable. The `$own` exclusions and the no-op skip are OUTCOME-redundant — mutating either alone leaves the post sequence unchanged, which is how duplicate guards hide each other. Their proofs assert the LOG, because what the exclusions alone decide is whether the job reports a race against its own row. One clause is left deliberately unproven and named as such in the record and the guard inventory rather than counted: the path-predicate failure branch has no fixture that can reach it. ## Also Round 2 left two comment paragraphs duplicated verbatim and a block header narrower than its block; both fixed. Stale prose corrected in the workflow ("dies WITHOUT posting", "post-write verification never runs for it", "this block only runs after a `success`"), `docs/ci-cd.md` ("the fence never re-counts", "the history is read twice" — it is three now), `ci.exemption-provenance` and `docs/guard-inventory.md`. refs #849 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019T79beF1Ufid3dXju4yqkF	2026-08-30 05:13:28 +02:00
timothyandClaude Opus 5	957a328f33	fix(849): round 2 — the uncertainty paths that still resolved toward success ... Two independent cold reviews (Codex/GPT-5.6 cross-family, and a cold Claude reviewer in its own worktree) converged on the same class: paths where "this job cannot establish what is on the head" still resolved by leaving the head alone, which protects a real verdict and leaves a forged one. Behaviour: 1. The four page-2 completeness refusals now replace the unknown state too. They were excluded on the reasoning that the probe fires when NO row for this context was on page 1, so there is no green of any provenance to leave standing — self-contradictory, since the only reason page 2 is read is that the row may be beyond page 1, which the probe's own message says. Accepted cost, stated in the record: a head with more CONTEXTS than the 50-row cap stalls every run; measured 2026-08-29, this repo puts 8 on a `main` head, and that case already stalled with an ABSENT check. 2. The no-mark downgrade covers every re-derivable write, not only `success`. Restricting it analysed the wrong PR: the damaging case is one that IS exemptible and got the generic `pending` only from a transient enumeration failure. That description carries no marker, nothing verifies it without a mark, and the next run re-derives it into the exemption with the human row below its own mark — route 2's damage through route 1's condition. `$REPAIR_DESC` stays exempt, being stronger and not re-derivable. 3. The fence branch that cannot trust its retarget count while holding a derived `success` writes the sentinel instead of abstaining. It is reached only after the classification DECLINED to inherit the row the head carries, so posting nothing left that row current; the message said the context "stays absent", true only of a head that had none. 4. Reconciliation needs a WITNESS: it may clear only over a complete history containing the sentinel's own row. `ex_unverified` means the combined endpoint just returned that row and `/statuses/{sha}` keeps one per POST, so a complete-but-empty history contradicts a write that demonstrably happened — and `page_statuses` accepts an empty page 1 as complete, which is what made it reachable. Both reviewers reproduced the clear-then-exempt outcome. The shipped positive test used exactly that impossible fixture, so it was pinning the defect; it now seeds the sentinel row, and an impossible-empty negative plus a witness mutation proof were added. 5. The mid-run "did this row change" comparison now includes the row ID. The two sentinels are byte-identical by design, so a mid-run replacement of one by another was invisible to a state/creator/description triple. Measured 2026-08-29 (Gitea 1.27.1, head 736649b3): the COMBINED endpoint carries `id` on every row, ids 14..30 ascending — the job had only ever read ids from `/statuses/{sha}`. Where a server omits it both sides are empty and the comparison degrades to the pre-existing text test. 6. The repair has a FLOOR — it may never write a description weaker than the one this run decided — and is skipped when it would rewrite what is already there. Widening the gate to every write meant a transient post-write read could rewrite a correct `$REPAIR_DESC` carry-forward with the machine-clearable sentinel, reversing the ordering rule the classification chain states. Writing the sentinel and failing the job are separate decisions, which is why `replace_unknown_state` and `replace_unknown_and_die` are two functions: the read refusals were already non-zero exits on `main` and stay red; the fence branch exited 0 there and still does, because an unreadable timeline is an ordinary hiccup and reddening every one is noise this file elsewhere refuses to add. Prose corrected where it now overclaimed: "the green never stands" after the post-POST re-check is wrong — it is live between the POST and the repair, so the check makes a permanent green TRANSIENT; "a later run reconciles this automatically" is wrong in the one case where the replacement costs anything, since finding a masked verdict UPGRADES to the human-only sentinel; and the mutation-proof framing claimed every mutant restores the exact predecessor, when two do, one restores the shape #742 withdrew, and the rest disarm clauses that have no predecessor. The quiet-timeline positive control now counts timeline walks, because a single POST is also what a skipped re-check produces. refs #849 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019T79beF1Ufid3dXju4yqkF	2026-08-30 05:13:28 +02:00
timothyandClaude Opus 5	e30702111f	fix(849): verify every write, and mark a head nothing could verify ... The gate's post-write verification had five routes that all ended the same way — an exemption `success`, or a generic `pending` a later run turns into one, standing over a human `failure`. Two of these were attempted inside #742 and withdrawn, and the withdrawal is what shaped this change. That attempt withheld the exemption by writing a GENERIC `pending`, which is exactly what a later run re-derives into `success` — it moved which run posted the forged green rather than stopping it — and it had no retry path, because this workflow triggers only on `pull_request_target` types, so a transient failure on a PR's last event stalled an exempt PR until a human nudged it. The fix therefore needs two properties at once: sticky, so a later run cannot re-derive it, and reconcilable, so a blip does not cost a head its exemption permanently. Neither the repair sentinel nor a generic `pending` has both, which is why there is now a second sentinel rather than a reuse of the first. What changed: 1. No high-water mark => the exemption is WITHHELD before the POST and the head is marked with the new `UNVERIFIED_DESC` sentinel. Withholding before the write rather than posting and repairing matters because the defect is known in advance: publishing a green to take it back opens a window branch protection, and an already-scheduled auto-merge, can see. 2. Post-write verification runs after EVERY write, not only `success`. A generic `pending` masks a rejection landing in its own write window just as well, and carries no marker, so the next run re-derives it with the human's row now below THAT run's mark. 3. `.description` is type-tested before `startswith`. `(.description // "")` does not replace a NUMBER, so `startswith` hard-errors on one, killing the whole count — the genuine verdict beside the malformed row is lost with it. 4. The retarget count is re-taken AFTER the POST on the exemption path, closing the PERMANENT forged green `ci.verdict-write-retarget-fence` listed as its residual 1. The retarget axis only: a push after the POST moves the head, so the status no longer gates that PR, while a retarget changes the effective diff with the sha unchanged. 5. An unreadable combined-status read retries once and then REPLACES the unknown state instead of declining to write. Declining protects a real verdict and leaves a FORGED one — an off-list `success` is the row #742 exists to revoke, revocation happens by re-deriving it, and the job then went red on a status branch protection does not read. One defect this introduced and fixed on the way: widening the post-write gate to every write made the job match its OWN row, because the machine-sentinel arm selects on a null creator. A run taking the carry-forward path POSTed `$REPAIR_DESC`, then found "a sentinel above the mark", then repaired to the identical description. `--arg own "$desc"` excludes it, by description rather than by id — the id of the row just written is not knowable there. Reconciliation is what bounds the stall: a later run pages `/statuses/{sha}` in full and either finds a `Review-verdict:` row underneath the sentinel — an established fact, so it upgrades to the repair sentinel, clearable only by a human — or finds none and clears it. It is sound because the two endpoints disagree: a masked verdict is invisible on the combined endpoint (latest row per context, which is the sentinel) and still present in the per-POST history. Tests: each fix is paired with a `test_MUTATION_…` proof that restores the exact predecessor text through a new `_run_classify(mutate=…)` knob, whose count assertion is the binding — a clause that has since moved substitutes zero times and fails loudly rather than measuring the unmutated body. Two CHAINED tests feed run N's real output into run N+1, because both sentinels are fixed points and a single hop cannot assert a fixed point: the raced-`pending` repair must survive the run that would otherwise grant the exemption, and the unverified sentinel must not decay while it cannot be reconciled. Docs: new record `ci.verdict-unverified-write-sentinel`; the now-false guarantee prose in `ci.verdict-write-retarget-fence` (its `rule:` frontmatter, the "resolves it" opener, "the fence above closes", the truncating-block claim and residual 1), `ci.exemption-provenance`, `docs/ci-cd.md`, `docs/remote-state-inventory.md` and `CLAUDE.md` corrected by concept rather than by phrase, per the scope boundary recorded on the issue. fixes #849 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_019T79beF1Ufid3dXju4yqkF	2026-08-30 05:13:28 +02:00
3 people	5d955000f3	fix(845): the verdict writer checks that the gate will honour what it just posted (#889) ... `review-verdict.yml` inherits an existing `review-verdict/h10=success` only from a status whose `.creator.login` is on its `H10_REVIEWERS` allow-list (#742). `post-review-verdict.sh` wrote those verdicts with whatever account owned the credential in the environment and never asked whose it was. Two coupled values, nothing asserting the coupling, and the failure was the silent kind: the status is written, the tool reports success, and the next `pull_request_target` event re-derives it and posts over it. The PR stalls with no visible cause. The writer now READS ITS OWN STATUS BACK, identifies that write by state and description, and refuses — before the verdict comment, so the surviving half-state is the documented `ask` one — unless the recorded creator is allow-listed. Measured after the write rather than probed before it: that tests what Gitea recorded as the author, which is the value the gate reads, and needs no scope beyond the repo access the POST already required. Membership is required for a `success` ONLY, mirroring the gate's own asymmetry: a `failure` is inherited from any attributable account, so requiring it there would refuse a verdict the gate honours and leave an off-list reviewer no supported way to record a rejection. The allow-list is DERIVED from the gate's own literal by the new `scripts/lib/h10-reviewers.sh` — one declaration, not two plus a parity test. It is a parse rather than a shared declaration both sides source because the gate runs against a checkout of the PR's BASE sha: a PR whose base predates such a file would not have it, and a missing `source` under `set -euo pipefail` kills the job, which posts no `review-verdict/h10` at all and blocks every merge including its own repair (#743). `scripts/post-review-verdict.sh` moves BEHAVIOUR-ONLY -> MUTATION in the guard inventory, which the manifest's own note called "the most valuable upgrade on this list". The declared clause lives in the GATE: rewriting `H10_REVIEWERS` while the posting account stays fixed reddens the accept path only if the writer reads the list live AND the comparison gates the outcome. Two defects were caught by probing the live instance rather than re-reading the code. Reading `.state` instead of `.status` per row would have refused EVERY verdict — a repo-wide deadlock, shipped green, because the test shim replayed the POST payload as the read-back body and so agreed with the parser by construction. Then a `(.status // .state)` fallback added as defensiveness recreated #845 exactly: the writer would accept a shape the gate cannot read and report success. Nine independent cold review rounds, all worktree-isolated, one cross-family (GPT-5.6 via Codex). Round 8 caught the most important one: a `set -u` "correction" made mid-branch had inverted a TRUE statement in live merge-gate code, because the probe used a plain `$UNSET` while the validator uses `${#arr[@]}` — different shapes, different behaviour. Withdrawn wholesale; both libraries are byte-identical to `main` again. Verification: full `scripts/tests` suite green (1278 passed, 2 skipped); the declared mutation executes every run and reddens its named proof with the manifest's `expect` string; every clause disarmed individually and confirmed to redden its own named test; live probes against Gitea 1.27.1 for the row shape, the description round-trip, the paging order and the required-check list. Docs: `ci.exemption-provenance` records the coupling as asserted rather than as a tracked residual, plus `docs/ci-cd.md`, `CLAUDE.md`, `docs/guard-inventory.md`, `docs/remote-state-inventory.md`, `ci.script-tests-job` and the `script-tests` population comment in `pr-checks.yml`. Deferred: the refused-verdict residual (a non-inheritable status left standing with no comment) is the `ask` half-state `release.verdict-writes-status-before-comment` designates as safe; a second corrective write is the sticky-sentinel mechanism #849 is separately designing. fixes #845 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-30 02:43:08 +00:00
3 people	94a3d13495	fix(836): never pass --depth to a checkout that may already be complete (#884) ... `git fetch --depth=N` grafts a complete clone shallow. `scripts/ci-detect-docs-only.sh` applied a depth chosen for its three `fetch-depth: 2` consumers to `build`'s `fetch-depth: 0` checkout, so the `git describe --tags` in the next step found no reachable tag and a `|| echo v0.0.0` fallback turned that into a version: every `:latest` image shipped `InformationalVersion 0.0.0-<sha>` from 2026-07-17 (#416) until now. Both fetch sites now go through `fetch_ref`, which passes `--depth` only when the checkout is already shallow. `Compute version and tags` fails the job instead of defaulting, so no `:latest` is published rather than a mislabelled one; releases are unaffected because the tag path never calls `describe`. Ships a guard that drives the real script over real `file://` clones with a negative control, a declared clause mutation, and a decision record `ci.fetch-depth-never-grafts-a-complete-clone`. fixes #836 Co-Authored-By: Claude Opus 5 (1M context) &lt;noreply@anthropic.com&gt; Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-29 23:55:29 +00:00
timothyandtimothy	e8f80c42ce	fix(820): derive where Complete&lt;T&gt; is APPLIED, not just what it means (#883) ... `Complete<T>` (#807) makes SPA full-replace bodies fail typecheck when a builder omits a schema member. Nothing checked it was APPLIED: `completeRequest.guard.test.ts` proves the type's semantics and would stay green with every annotation deleted, and `test_optional_request_members.py`'s COVERED disposition — "the builder is annotated `Complete<T>`" — was a claim about another language's source that nothing verified. Adds `completeAnnotationScan.ts` (compiler-API scanners) + `completeAnnotations.guard.test.ts`, with a synthetic-source fixture suite. Two derived populations: the `Complete<…>` annotations (SPA AST ∩ git index) and the droppable schemas (parsed from the generated `v1.d.ts`, a pass-through of the OpenAPI `required` array). It asserts a production annotation per schema dispositioned as needing one, NO annotation on the server-computed and load-bearing-omission schemas, that every `Complete<X>` resolves to a generated schema rather than a hand-written mirror, and set equality between droppable schemas and the reviewed dispositions. `test_complete_annotation_dispositions.py` cross-checks that table against the authoritative Python one and ships a declared, harness-executed mutation. Found one live defect: `playouts.ts` declared two request types as hand-written mirrors SHADOWING generated schemas of the same name, so their `Complete<>` was checking a local copy rather than the contract — the #754 mechanism wearing the annotation meant to prevent it. Eight review rounds, seven BLOCKED, two independent cold reviewers. A wrapper-signature scanner was built and REMOVED: every blocker traced to that one mechanism (obligation on the wrong population; reachability mistaken for protection, since `Complete<T>` is shallow; body discovery keyed on a parameter name, then parameter-vs-local; and finally `export function` → `export const` blinding the scanner and its cross-check together). Five defects from one mechanism, so the mechanism went rather than a sixth patch. Residuals stated in §4b, the guard-inventory row and the record: per-SCHEMA not per-site or per-wrapper; token presence not liveness; the phantom direction unchecked (#777); a second `setupFiles` entry could discharge; and plugin-level population integrity borrowed from the sibling guard. fixes #820 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-29 22:06:38 +00:00

3 people	90f96c14a5	fix(803,664): fence the HEAD alias on the PR timeline's pull_push count (#873) ... A force-push H1 -> H2 -> H1 spanning `pr-changed-files.sh`'s paging leaves its final `.head.sha` comparison equal while the middle pages came from H2, so a mixed file list could produce a docs-only exemption `success` no single head ever justified. The base alias had been fenced since #706 by a monotonic `change_target_branch` count; the head axis had nothing, and three contracts asserted otherwise. `count_retargets` becomes `count_pr_mutations`: one timeline walk, two tallies, one shared trust flag, a separate fence arm and diagnostic per axis. The advisory hook re-reads `.head.sha` at the same hoist and off the same response as the base re-read. All three overclaiming contracts are corrected, plus four paraphrases the first sweep missed. Measured, not assumed: Gitea 1.27.1 still serves no `files` on `compare/{base}...{head}`; every push is a `pull_push` event and its count cannot alias; PR #761 really went `8798a1d -> 830a407 -> 8798a1d`; and Gitea creates the push comment BEFORE emitting the synchronize notification, so a run cannot abstain on its own trigger. Two pre-existing fail-opens in the shared walk were found by review and fixed: an empty ARRAY first page was trusted on any page while the `null` arm required `page > 1`, and no row was validated before `.type` was selected on. NOT closed, and documented rather than overclaimed: the walk's `null` terminator is defeatable, because Gitea pages before it filters (#870).

timothyandtimothy	4b3f6f6c90	fix(786,789): workflows declare their own per-job metadata; guard populations derive from it (#872) ... Closes #786 and #789, bundled because working either alone would build the artifact the other removes. Every job in all six tracked workflows declares `env.CI_JOB_ROLE` (guard/report-only/none); the `docker-build.yml` jobs also declare `env.CI_EXECUTION_CLASS` (toolchain/bare-runner). Both guard populations derive from those markers; the `TOOLCHAIN_JOBS`/`BARE_RUNNER_JOBS` literals are deleted. A missing or unrecognised marker is a hard failure in both checkers. #789's literal had a real justification — set equality between two DERIVED sets is blind to a member leaving both at once — so the marker is the anchor that replaces it, and the cost (proximity to the `container:` block) is paid by a THIRD derivation from each job's own steps, which is also the only check that sees the failure #789 filed: a .NET step moved into a bare-runner job, where no set changes. The residual is disclosed: drop the block, flip the marker AND hide the tool behind a script and all three go blind, bounded by the failure mode being a loud missing-binary crash. #786's guard jobs join a machine-checked population: a new `test_workflow_job_guards.py` asserts set equality both ways against a new "Workflow-job guards" table, and the four jobs with no dropped-step guard each carry a recorded decision. Two issue claims were refuted by measurement: #789's "editing docker-build.yml re-points the pin" (the pathspec is `docker/ci` only) and #786's job count (17, not 15). Four cold adversarial review rounds across two model families; rounds 1-3 BLOCKED, all findings fixed and each fix demonstrated by reproducing the reviewer's own test. The recurring defect class was prose drifting from code, including a mechanism claim in the decision record that execution refuted.

timothyandtimothy	e11d577193	docs(796): verification code is code under test, and the proof it was claiming an exemption from (#871) ... Records `testing.verification-code-needs-its-own-proof`: the proof obligation follows the VERDICT rather than the file, so it binds harnesses, wrappers, timeouts and checkers — not only the files the guard population derives. The issue asked for a stated position on whether non-guard checker scripts get mutation proofs. The position as first written claimed `scripts/mcp_smoke.py` "cannot participate" because driving it needs the gitignored `.mcp.json` and a cold-built language server. Cold review refuted that by execution: it takes its config path and server name as positional arguments. The record had failed its own headline rule on the one claim its decision rested on, so this ships the proof instead of the exemption. - `scripts/tests/test_mcp_smoke.py` — a hermetic stub JSON-RPC responder and six cases pinning the defects the checker has already had, with the positive control as a fixture the refusal tests depend on, so a node-id or `-k` selection cannot skip it. - A declared clause in `mutation_manifest.py` targeting the unguessable request id, using the `guard=test / target=script` shape that already exists for `mutation_harness_lib.py`. Witnessed red: `id_init = 1` makes the pre-answer accepted at `initialize` (rc 9 -> 10), and only that test moves. `mcp_smoke.py` still gets no inventory row — one is rejected as a phantom (measured). The row goes to the test file, which joins the derived population automatically. Five cold-review rounds, four BLOCKED. Round 2 caught a `ruff format` red that would have failed `script-tests`. Rounds 3-5 found only hand-maintained counts and uniqueness claims in prose, three of them created by the previous round's fix; that class was deleted rather than corrected again, per this record's own stop-and-subtract rule.

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

Trap recorded: the PR API reports `mergeable: true` while such a merge is refused. Left explicitly dated with reasons: push-supersession auto-cancel, `pull_request_target` overlap, `--depth=1` no-merge-base, and the scope-enum/`reqRepoWriter`/403 items.

timothyandClaude Opus 5	462118d98d	fix(763): round 9 — assert the repair's reason positively, not by absence ... A sixth cold review found everything in round 8 clean except one line, and it is the rule this branch keeps rediscovering: the test pinned the new `raced_why` only by asserting the ABSENCE of the borrowed wording. Measured — replacing the string with `zzz` left the suite green while an operator would get `::error::… — zzz.` beside a sticky sentinel. The sibling test 330 lines away states the rule and follows it; this one did not. Now asserted positively, with the em-dash and full stop discriminating the `::error::` reason from the `::warning::` text that continues ", which cannot be true". The `zzz` mutation reddens it. Three nits from the same review, all verified by execution rather than reading: - the earlier fixture's row was excluded by the strict `> $since` because the mark became its OWN id, not because it sat below the mark. - the predecessor comment said `main` "warned only on `null`". True of the two EMPTY shapes being contrasted; an empty body and a non-array object warned as well. Scoped. - `docs/ci-cd.md` and the record described the `::error::` as a two-way split (found vs unverifiable). Round 8's whole argument is that a complete read returning an IMPOSSIBLE answer is a third case, not a variety of the second — which is the operator-facing point, since it decides whether to go looking for an API failure that never happened. Both now say three. The review re-verified, by comment-stripped diff, that round 8 changed no executable line beyond the `raced_why` string and the if/elif restructure, and independently reproduced both inertness measurements and the `origin/main` predecessor behaviour.

timothyandClaude Opus 5	4164efbc3e	fix(763): round 8 — a fixture must pose the scenario it narrates ... A fifth cold review confirmed the gate's behaviour is correct and proof-backed, and blocked on three non-behavioural items. All three fixed; none touches the shipped logic. MEDIUM — the round-7 fixture narrated a raced human verdict it did not construct. `null-page1-after-post` appended the row unconditionally, so it also joined the PRE-write read and lifted the high-water mark above itself; removing it changed nothing. The reviewer's suggested fix was to gate the append on the post-write read. Measured after gating: still inert, because page 1 answers `null` before any row reaches the wire. So the row is gone rather than gated, and the prose now describes what the fixture actually poses: a response asserting an empty history for a sha this job wrote to must not be accepted as proof that nothing raced. Whether a verdict really raced is not modelled and does not need to be — the response is not evidence either way. A row the test cannot observe is decoration that reads as coverage, which is the same class this branch has now been blocked on five times. LOW — the comment claimed the predecessor "at least produced a `::warning::`". Half false, measured against `origin/main`: its `jq -e 'type == "array"'` gate ACCEPTED `[]` silently and warned only on `null`. What is actually new is that the paged walk reports such a read as a SUCCESS. LOW — when the empty clause fired it set `ph_ok=no`, so the log said "could not be read completely" beside a walk that completed on a validated terminator. The answer was impossible, not unreadable, and an operator holding a sticky sentinel needs to know which. It now carries its own `raced_why`, asserted by the test. Both clauses mutation-proved: disarming the empty check, and reverting to the borrowed wording, each redden the named test.

timothyandClaude Opus 5	e6f04cc739	fix(763): round 7 — reject an empty post-write history, and the fourth overclaim ... A fourth cold review returned NOT-MERGEABLE on two Mediums. Both fixed, plus its three Lows. MEDIUM, and a defect this branch introduced. Tolerating a `null`/`[]` page 1 as "complete, zero rows" is correct for the PRE-write caller — a head nothing has posted to genuinely has no statuses — and impossible for the POST-write one, which has just written a row to that sha. The body is well-formed, so nothing retries it, and the walk reports success: `raced=0` concluded from a list that cannot be real, on the one path whose failure direction is toward SUCCESS. Worse than the code it replaced, which at least emitted a `::warning::` — a logged fail-open had become an unlogged one. Reviewer measured both directions. The post-write caller now rejects an empty result itself; the walk stays caller-agnostic because the pre-write caller genuinely needs the empty answer. This is NOT the withdrawn currency witness: that asked whether ANY row sat above the mark, which an unrelated newer row satisfied while the rejection stayed hidden, and it fired on schema-valid staleness. This asks only whether the list is EMPTY — a state no unrelated row can produce and no ordering can disguise. It carries neither defect. Proved by fixture; disarming it reddens the named test, and the previously-uncovered `null`-at-page-1 clause is now covered too. MEDIUM — the fourth overclaim of the same class, in the decision record body: "Uncertainty must fail closed at both ends … Both repair now." The page-2 probe was DELETED, not converted; it repairs nothing. It also contradicted the record's own `rule:` ("the two directions are NOT symmetric") and the bullet directly beneath it. Round 5 retracted this wording in `docs/ci-cd.md` only — the sweep was by subject, not by the retracted words. Also fixed: - the record presented "an empty FIRST page is legitimate" as a property of the walk; it is a property of the pre-write caller. - `docs/ci-cd.md` called the numeric-only id comparisons a fix for mark inflation; they are a TYPE guard, closing the string half. A corrupt but genuinely numeric id still inflates the mark — not attacker-controllable, since ids are server-assigned, and now stated rather than implied. - `test_a_partial_mark_is_SAFE...`'s self-guard promised to detect that the fallback ran; it keys on a warning emitted by a different condition, so deleting the fallback left it green. Its sibling is what reddens; the message now says what it actually pins. - the order-faithful fixture appended the job's own POST after the reversal, serving the NEWEST row on the OLDEST page — the opposite of DESC, in the one fixture that exists to be ordering-faithful. - "twice per walk" for the wasted sleep; it is once per walk, twice per run. - a dead counter read in the DESC mode. Rebased onto b16ec15d6 (the other session's #781/#799 docs work; no file overlap, no conflicts).

timothyandClaude Opus 5	89db6022d9	fix(763): round 6 — measure the partial-mark fallback under the REAL ordering ... A fourth cold review (Opus, isolated worktree, tests/double/docs focus) reported no correctness bugs in shipped behaviour but two coverage defects on exactly the two things this change advertises. Both are closed. The partial-mark fallback's safety is a claim ABOUT THE ORDERING — page 1 holds the newest rows, so a walk that fails later still saw the true maximum. The fixture pinning it served ASCENDING ids, i.e. the arrangement the design calls unsafe, and passed anyway because the raced row's id sat above even the partial mark. It could not distinguish safe from unsafe. The stub now HONOURS the sort parameter: order-faithful modes serve DESC by default and ASC when the request asks. The new fixture holds a PRE-EXISTING base-mismatched verdict at id 7055 among 60 rows. Under DESC the salvaged mark is 7059 and that row is below it — the exemption correctly stands. Under ASC the mark would be 7049 and that untouched row tests as NEWER, a sticky repair on a head nothing raced. So re-adding `sort=highestindex` now reddens by BEHAVIOUR, not only by the structural assertion added in round 5. Measured: re-adding it reds both tests. Most modes stay ordering-blind on purpose and now say so: they test walk COMPLETENESS, which is order-independent, and insertion order is what lets a fixture place a row beyond page 1. Also fixed: - `null` is accepted as an empty page. An array-only gate is the exact shape of #751 — `count_retargets` had one, the timeline really did return `null` past the end, and the fence withheld EVERY exemption from the day it shipped. The same narrowing here is worse, because this walk's failure is the STICKY sentinel: every exempt PR would need a hand-posted verdict, per head. Tolerating `null` cannot misread `[]`. Proved by fixture. - the fail-closed comment said "past the 1000-row page cap"; the bound is 950, as the walk's own comment and both docs already said. - the docs claimed "only a read returning no rows at all abandons the mark". False: a VALIDATED empty history yields a mark of 0 and is not abandoned — that is the normal first run. What abandons it is a read that both FAILED and returned nothing. Corrected in ci-cd.md and the record `rule:`. - a comment pointed at the page-2 probe "a few lines further down"; it was deleted, so the deixis pointed at nothing. - the stub claimed its logical-read counter "is only reached on a SUCCESSFUL page-1 serve" — measured false; it counts page-1 requests, retries included. - five `(round N)` markers removed. A round number is session chronology and does not parse for a reader who never saw it (`docs.no-session-narrative`); an issue number does. The four that remain predate this change. Verification: `scripts/tests` 1096 passed, 2 skipped. Thirteen executed mutations across rounds 2-6. The reviewer independently re-ran the earlier matrix and confirmed it, with one correction carried here: two of those mutations redden MORE than their named test, so "each reddening exactly its named test" was wrong — they redden at least it. refs #763 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-28 17:34:08 +02:00
timothyandClaude Opus 5	53ee44cbc1	fix(763): round 5 — correct the overstated motivation, and fix the string-id twin ... A third cold review (Opus, isolated worktree) returned NOT MERGEABLE with one High and three Medium. All are addressed. HIGH — the stated motivation was wrong, and self-contradictory once round 4 landed. Under the server default (`created_unix DESC`) page 1 holds the NEWEST rows and ids are monotonic with `created_at`, so page 1 already carried the true maximum id AND every row newer than the mark — the only rows the post-write check selects on. A single-page read therefore missed a raced verdict only if more than 50 rows were created INSIDE the write window, not merely on "a head with more than 50 rows", which the issue, the comments and the docs all asserted. Reviewer executed an order-faithful DESC stub: a page-1-only reader repairs identically to the full walk. What actually removed #761's stall is retiring #751's page-2 probe, not the paging. The walk still earns its place, for a reason now stated instead of the false one: it stops the gate's one fail-toward-SUCCESS path depending on an undocumented ordering the server honours only coarsely (page 1 came back `114,112,113,111,110`). That measurement was deleted in commit 1 and is restored, since round 4's safety argument rests on exactly it. MEDIUM/real defect — the string-id TWIN, live on `main` and one expression away from the fix already made: `select((.id? // 0) > $since)`. jq orders strings above every number, so a PRE-EXISTING row with `"id": "3"` reads as newer than any mark, is counted as having raced the write, and gets the sticky sentinel plus a false "was overwritten" on EVERY later run — a permanent per-sha stall no re-trigger clears. Now numeric-only, with a test. Also fixed: a non-empty history carrying no numeric id was collapsed to a mark of 0 (making every pre-existing row look newer); it is now reported unusable and the check is skipped. `sleep` no longer fires after the final attempt. Three unpinned clauses now have tests, each proved by an executed mutation: - the page cap is a refusal, not a terminator (1050-row fixture) - the `::error::` found-vs-unverifiable distinction (forcing `raced_why=human` reddened nothing before) - the walk requests no sort order — a structural guard on round 4's withdrawal, which nothing mechanical protected. It reads request LINES, not comments, since the withdrawal note names the parameter to explain it. Honest scoping, not new code: the test double is ordering-blind, so the paging tests prove WALK COMPLETENESS, not that a real raced verdict would otherwise be missed — under DESC it would not be. The stub comment and the docstrings now say so rather than implying the stronger claim. Docs: `ci-cd.md` and the record's `rule:` carry the corrected reachability, the DESC dependency of the partial-mark fallback, and both rejected alternatives stated as rejected alternatives rather than as draft chronology (`docs.no-session-narrative`).

timothyandClaude Opus 5	007d2fd3df	fix(763): round 2+3 — close the fail-opens the paging change introduced ... Two independent cold reviews (Codex GPT-5.6 cross-family, and an isolated Opus agent) converged on the same blocker, which is fixed here along with everything else they found. BLOCKER — the mark walk turned a fail-closed case into a fail-open. The high-water mark gates the post-write race check entirely: `max_id_before=-1` skips it. Before paging, only a failure of the single page-1 request could reach that. Requiring a COMPLETE walk newly routed a page-2 hiccup, an over-cap history, or one malformed id on a later page into the same hole, so a human rejection racing the write was left green where `main` repaired. A partial list now still yields a mark: it can only be LOWER than the true maximum, which makes the check more eager, never blinder. Only a read returning no rows at all abandons it — the pre-existing #849 gap, unchanged and now asserted by a test so it stays visible. WITHDRAWN — the "currency witness". It produced two defects from one mechanism, which is the signal to remove rather than patch twice: counting ANY row above the mark does not witness this job's write, so a stale-but-valid snapshot carrying an unrelated newer row passed while hiding a rejection; and a schema-valid stale read is not retried, so one such response turned a transient anomaly into a permanent sentinel. The hazard has no mechanism here either — Gitea is a single instance with no read replicas. Removing it restores the pre-change exposure on that path, a non-regression. Also fixed, each a fail-open with a fixture and an executed mutation: - `.creator` is type-tested before indexing. `.creator.login` on a non-object exits jq 5 and `set -e` took the step down after the green was posted and before the repair. Reproduced by both reviewers. - the mark is the max over NUMERIC ids only. jq orders strings above every number, so one `"id": "99999"` passed the numeric gate and inflated the mark until nothing looked newer. - an unusable `raced` count now repairs instead of "not acting on it". - `sort=highestindex` (ASC, measured) so a row inserted mid-walk appends at the end rather than at position 0 on a page already read. An unknown sort value silently falls back to DESC, so this is insurance, not load-bearing, and the comment says so. - `ph_ok`/`ph_rows` renamed off `read_existing_verdict`'s `st_ok`. No live bug, but a name collision in a 1400-line step. Tests the reviews showed were missing, each proved by an executed mutation: - verdict beyond a SHORT page (a deliberately unfaithful truncated response — against a faithful double a short page is always the last, so the rule "terminate only on an EMPTY page" was unobservable) - pre-write paging failure still yields a usable mark - pre-write read returning nothing abandons the mark and says so - a TRANSIENT page failure is retried (the retry was unproven code: every other error mode fails on every attempt, so disarming it reddened nothing) - a string id cannot inflate the mark - a malformed `creator` row does not kill the job Stub corrections, both the same class as the earlier `[]`-vs-`null` gap: it served one flat list (so paging was unobservable) and computed its own-post id with `max()` over mixed str/int, which raised TypeError and made the string-id test pass because the DOUBLE crashed rather than because the mark was right. Mutation matrix, all executed, each reddening exactly its named test: retry disarmed; numeric-max reverted; partial-mark fallback removed; short-page terminates; page-1-only walk; post-write fail-closed flipped open; jq type-guard reverted. The unusable-count arm is unreachable by any fixture and is annotated as such rather than claimed as proved.

timothyandClaude Opus 5	4368cc8cbe	fix(763): page both /statuses/{sha} reads to a validated terminator ... `review-verdict.yml` read the per-POST status history twice with a single `?limit=100` request. `limit` clamps to the server-wide `MAX_RESPONSE_ITEMS` (measured 50), so on a head carrying more rows than the clamp both reads saw a partial list. The high-water mark was only page 1's maximum, and — the direction that matters — a raced human verdict beyond page 1 was invisible to the post-write race check, leaving a forged green over a rejection. Both reads now walk to a validated empty page (`[]` on this endpoint, measured 2026-08-28 against PR #761's 114-row head: pages 1-2 return 50, page 3 returns 14, page 4 is `[]`), never terminating on a short page, under a 20-page cap and retrying each page once. Correctness does not depend on the cap value. This retires #751's page-2 "assume raced" probe, which repaired every head that outgrew one page. It fired on Renovate PR #761: an `::error::` claimed a human verdict had been overwritten on a head carrying none, and the sticky sentinel then refused re-exemption on every later run. Two properties replace it. Uncertainty now fails closed at both ends — the unreadable-history branch warned and left the exemption green while the page-2 probe repaired on the same uncertainty, one check disagreeing with itself; this is affordable only because paging removed the common trigger. And the post-write read must witness the job's own write: reaching a validated empty page proves the walk finished, not that it saw a current list, so at least one row above the pre-write mark must exist because the job just posted one. The `::error::` now distinguishes a verdict actually found from an unverifiable read. The sentinel description stays generic — the classification recognises it as a fixed point, so its wording is load-bearing. The stub gained faithful paging (50-row slices, `[]` past the end, one snapshot per logical read so a counter mode cannot describe two different histories across pages) and, separately, modelling of the job's own POST appearing in the history — which it had never done, so in its world every ordinary run looked like a head nothing had been posted to. `own-write-invisible` withholds exactly that detail as the negative control for the currency witness. Mutation-proved by execution, one clause at a time: - walk reads page 1 only -> RUNNING_PAST_PAGE_1_is_PAGED_and_the_exemption_ STANDS, raced_verdict_on_PAGE_2_is_detected_and_repaired and both UNREADABLE history tests go red - currency-witness zero branch deleted -> CANNOT_SEE_OUR_OWN_WRITE red - fail-closed flipped to fail-open -> both UNREADABLE history tests red Verification: `scripts/tests` 1085 passed, 2 skipped; decisions_validate and build_decisions_catalog --check both exit 0. fixes #763 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-28 17:34:07 +02:00

Closes the push route into ci-image.yml (#744) and ships the persist-credentials guard that was waiting on it (#835). ci-image.yml's push trigger had no branches: filter and was path-scoped to docker/ci/** AND to the workflow file itself. Gitea resolves a push workflow's definition from the pushed ref, so any branch push touching those paths ran that branch's own YAML on a docker-capable runner holding the credential that writes ersatztv:prod and the ersatztv-ci:<sha> five container: jobs execute. Be precise about what the filter buys: it is loaded from the pushed ref like the rest of the file, so a branch that deletes it re-enables the route. This closes the DRIVE-BY case - publication as a side effect of an ordinary push - and is not a boundary against a writer who intends to run their own YAML. The wider class is #853. The self-reference left both paths: and ci-image-pin's expected in the same change - a decided tradeoff with both prices stated, not a necessity. Branch publishing moves to workflow_dispatch, probed live: run 2340 on this branch published ersatztv-ci:43b1e45 and left :latest unchanged.

timothyandtimothy	d68ce42fcb	fix(742): inherit an h10 verdict only from an allow-listed reviewer (#850) ... `review-verdict.yml` decided whether an existing `review-verdict/h10` was worth INHERITING by testing `.creator.login != null` — satisfied by any account's credential, including the `renovate` bot's `RENOVATE_TOKEN`, a `write:repository` PAT that cannot be scoped down the way #697 scoped the registry credential. The test is now membership in `H10_REVIEWERS="timothy"`, a literal in the base-resolved definition. The design that survived 11 cold review rounds: * `read_existing_verdict` carries TWO flags. `ex_human` (attributable AND allow-listed) gates INHERITANCE; `ex_attributable` gates the last-moment re-read, which asks the opposite question and must stay broad. Narrowing both — the first draft — makes the job post its exemption over a mid-run rejection, and the post-write repair does not cover that. * The two calls no longer compute an identical predicate, so "changed" is made explicit: the state/creator/description triple from the first read is snapshotted and compared. * The allow-list governs an inherited `success` ONLY. An existing `failure` inherits on attributability alone, because inheriting a rejection can only withhold an exemption while re-deriving one can turn it green on an exempt PR. A symmetric rule was a measured fail-open. * The post-write raced check stays broad — not because narrowing would let a rejection go green (a real reviewer is on the list by construction), but for the misconfiguration case. Two mechanisms were WITHDRAWN rather than patched a third time, and both withdrawals are recorded in `ci.exemption-provenance` so they are not re-attempted: a `::warning::` annotation that produced three defects in three rounds, and a post-write fix whose generic `pending` would have been re-derived anyway and which had no retry trigger. Verified: the inheritance predicate driven against the LIVE Gitea API on a probe-named context, both allow-list directions; every clause mutation-proven against the shipped file; `scripts/tests` 1012 passed, 2 skipped. Follow-ups filed: #845 (post-review-verdict.sh does not check its own account is allow-listed) and #849 (post-write verification: three routes leaving an exemption `success` over a human `failure`, plus the retarget fence's post-POST gap, plus the prose sweep that lands with the behaviour). fixes #742 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-27 02:52:02 +00:00
timothyandtimothy	469d19852c	fix(788): one declarative H10 verdict vocabulary, derived by both sides (#846) ... The verdict words lived in two hand-written shell copies — the `case` arms of post-review-verdict.sh (write) and the POS_RE/NEG_RE regexes of check-review-verdict.sh (read) — held together by nothing but a comment that had already gone stale. scripts/lib/review-verdict-vocabulary.sh now declares them once and both sides derive; neither script enumerates a verdict word any more. Only the WORD SET moved. The grammar stays in check-review-verdict.sh, where every #629 false-open actually lived. No parity test: #774 shipped one and withdrew it after six rounds, because a regex over shell source is not a shell parser. The proof is behavioural and graded MUTATION — the harness restores the pre-#788 hardcoded POS_RE each run and requires it to redden. Enforcement is a DATA dependency, not a control-flow gate. Review round 1 found a real fail-open in the first commit: `${#arr[@]}` is nounset-safe only for a declared-empty array, and under `set -u` that error inside a function called as `if ! validate` skips BOTH branches — so on the reader (deliberately no `set -e`) an explicit BLOCKED @ head classified `positive`, exit 0. Validation now sets a sentinel on its last line and the derived views refuse without it. Six cold review rounds; rounds 2-6 found no fail-open across differential fuzzing (4788 / 2612 / 7560 payloads, zero divergences from origin/main's grammar), sentinel forgery, environment poisoning, declare -p evasion on bash 5.3 and 3.2, path/symlink resolution and probe TOCTOU.

timothy	8c72a5de9e	docs(772): correct the twins of two claims this branch already fixed ... Both remaining review findings were the same shape as the one before them, and it is the shape this repo keeps recording: a claim corrected in one place, its copy left standing somewhere else in the tree. * `docs/ci-cd.md` said "gates nothing" in the small-lane paragraph while the section 1441 lines below said the opposite. A red preflight lands in the PR's combined status, which the merge gate reads (#598) — what it does not do is SKIP the jobs it diagnoses, and that is now the sentence in both places. * Two docstrings in the preflight's test file still described the disarmed script as warning and exiting 0. Built the mutant and ran it: it emits an error and exits 1. The exit code separates nothing now that an unverifiable answer fails too — the DIAGNOSTIC is what the mutation destroys, which is what `mutation_manifest.py` already said and the prose next to it contradicted. Nits from the same pass: the admin-cron URL is quoted (`?` globs in zsh, the operator's shell); the retry assertion's message quoted a threshold it does not use; the arm table omitted the malformed-credential shape the code and tests both have; `buildx inspect` no longer `--bootstrap`s a builder just to read its name, and an empty capture no longer produces a noisy `buildx use ""`. Swept the tree for the shape rather than the two reported lines: the surviving "exits 0" and "could-not-tell" hits are other subsystems, or the concept named as a concept. refs #772	2026-08-23 00:23:44 +02:00
timothy	30640bb780	fix(772,792): close the fix-round review — the doc still described the semantics the fix reversed ... The re-review's one HIGH was mine and was the obvious one to miss: the previous commit changed the preflight so an unverifiable answer FAILS, and left a `docs/ci-cd.md` paragraph two screens away still saying "anything else is reported as could-not-tell". That paragraph is the one an operator reads when the job goes red, and it would have talked them into reinstating the defect. Replaced with the full arm table, including the two rows the first draft got wrong and why. * "gates nothing" was false in the way this repo has recorded before (#598): the merge-consent hook reads the COMBINED status, so a red preflight blocks the merge like any other red job. It does not SKIP the jobs it diagnoses; that is the accurate claim, in ci-cd.md and in the remote-state row. * The production retry defaults were evaluated by nothing — every test overrode both knobs. A test now drops the overrides and measures three attempts and a real pause, so editing the default to 1/0 (which would falsify the "a blip does not redden a PR" argument) goes red. * `journalctl -u gitea | grep ExecuteCleanupRules` is not a reproduction: that identifier reaches the log only through slow-query warnings, so an empty grep on a healthy host reads as "the rule never ran" — the inverse. Replaced with the admin cron API, which answers deterministically. * The recovery recipe's `docker buildx use default` needs the containerd image store to `--push` (both named hosts have it, checked today) and mutated the operator's builder selection without restoring it. * The stub's comment claimed both halves of real curl's transport failure mattered; only the exit status is observable, because `|| resp=""` discards what curl printed. * The empty-half credential refusal echoed the username; it needs no value at all. The 401/403 arm aborts the remaining pins while 404 continues — deliberate, now stated. * `curl -u "$VAR"` puts a credential in argv, and this job runs container-free on a shared host. NOT fixed here: it is the shape all five `scripts/` callers already use, so fixing one site leaves the class and splits the codebase.

timothy	0cf355e494	fix(772,792): address both cold reviews — an unverified pin is no longer a green job ... Two independent reviewers (one cross-family) converged on the same defect, and it was the important one: the preflight WARNED and exited 0 on every answer that was not 200 or 404, so a missing `curl`, a moved registry or a DNS change would have left it green forever — "the check could not run" presenting as "the pin is fine", in a script whose own header disclaimed exactly that. Unknown answers are now retried (3x, 5s) and then FAIL, with wording kept distinct from the deleted case because the two send an operator to different places. Also from the reviews: * An absent secret does not arrive as an unset variable. `${{ secrets.X }}:${{ secrets.Y }}` interpolates to ":", a perfectly non-empty and perfectly useless credential, and the tests covered only the unset shape. Both halves are now required, and the parametrised test drives the production shape. * HTTP 200 is not a manifest. A proxy or a login page answers 200 too, so the body is fetched and matched for `schemaVersion` (a shell `case`, so no jq dependency and no pipeline that can inject). * The curl stub ignored `-u` and answered 200 regardless, so deleting the real `-u` would have left the suite green while the live registry rejected every request. It now 401s an unauthenticated read, as the registry does. * The mutation's declared diagnostic changed with the script: now that unknown fails too, the exit code no longer separates "deleted" from "could not check", so the proof turns on the message and `expect` says so. * docs/ci-cd.md: `scan` is no longer the only `docker-build.yml` job on the small lane, so the tag-push exclusivity claim and the lane membership were both false. Fixed. * "Immutable" was overstated: `ci-image.yml` tags `rev-parse --short HEAD`, so a dispatch or a weekly no-cache run at the same HEAD republishes that tag from a rebuilt image. Stated, along with what the rebuild recovery does NOT restore (mutable bases and apt, so equivalent rather than bit-identical). * The recovery recipe left you in a worktree checked out at the pin commit — where the verify script does not exist, and where the workflow carries the pre-bump pin. It now keeps `$repo`, returns, and removes the worktree. It also needed BuildKit's `http = true` caveat: the container driver does not inherit the daemon's insecure-registries. * The root cause carries its evidentiary limit and its reproduction commands, and says what to conclude if a pin vanishes after server-management#842 lands (refuted, not re-applied). * The `ci.required-job-step-execution-markers` carve-out named one container-free job; there are two now, and the membership is what rots. * The decision record's `''` YAML escapes leaked into rendered prose; "status, no comment -> ask" is qualified (a prior positive verdict for the SAME head still satisfies condition (c)); "exits 1" is "exits non-zero" (usage exits 2, jq its own status, signals 128+n). refs #772 refs #792 Decisions-Edit: yes	2026-08-22 23:25:26 +02:00
timothy	5ba442c11c	fix(772,792): name the missing toolchain image, and stop a refusal leaving a verdict comment ... #772 — the pinned CI toolchain image can be deleted out from under us, and when it was (2026-08-11..13) all five `container:` jobs died at image pull, both required contexts included, with the cause buried in each job's log. Root cause is registry-side and is now established rather than guessed: an owner-level Gitea package cleanup rule (keep_count 15, remove_days 1, remove_pattern `.*`, keep_pattern no 7-hex sha can match) deletes a sha tag once 15 newer versions exist, and `ExecuteCleanupRules` ran nightly through the window. The `ersatztv` package carries the same rule's fingerprint exactly — every sha tag older than the 15-slot window is gone, every keep_pattern tag back to 26.3.1 survives. Version deletes leave no audit row, so the specific run cannot be replayed; that limit is stated where the claim is made. The durable fix belongs to the registry's repo: server-management#842. What lands here is what a consumer of someone else's registry can do: * `toolchain-preflight`, a container-free job (a job consuming the image could not run to report it missing) resolving every pin against the registry and failing with a message that names the tag and the recovery. Not a `needs:` of the jobs it diagnoses — gating five jobs behind a checkout and one curl taxes every green run to speed up a rare red one, and they already fail fast. * Only HTTP 404 means gone. Everything else is could-not-tell, and rejected credentials fail rather than pass as unknown — "the check could not run" must never present as "the pin is fine". * A recovery path that does not need CI: rebuild the SAME tag from the commit it names and push it. The push half was verified against this registry on 2026-08-22 with a throwaway package (created, resolved 200, deleted). #792 — the reported defect was the exit code, and re-measuring says that premise is false: every no-status path already exits 1, and eight refusal modes now assert it against the real predecessor, where they pass. The observed 0 came from the invocation, not the script. What WAS broken is the half-state the issue describes second: the comment was written before the status, so every refusal left `Review-verdict: MERGEABLE @ <head>` on a PR with no gating status behind it. The two writes are now ordered status-then-comment, which makes the only reachable half-state the safe one — a status with no comment leaves the merge hook's condition (c) with nothing to classify, which is an `ask`. The refusals themselves are untouched. Ordering rather than compensating deletion: an orphaned-comment cleanup needs a Gitea call, and these refusals are usually caused by Gitea being unreachable. Proof for the ordering is the split against origin/main's script: the 8 orphan/ordering tests go red there, the 8 exit-code tests stay green. fixes #772 fixes #792 Refs: server-management#842 Decisions-Edit: yes	2026-08-22 22:52:56 +02:00
timothyandtimothy	29d7a06e65	fix(806): guard populations over FILES derive from the git index, not a filesystem walk (#818) ... `testing.guard-derives-population-from-source` (#774) was silent on the commonest population in our own guards — files in a directory — and every one answered with a filesystem walk. A walk is not authoritative: it reports build output, generated shims and editor droppings, and differs per machine. #778 measured the cost by getting the same population wrong three times in one PR. CONVERTED (a completeness claim over tracked files): `test_guard_inventory.py`, `test_hook_fire_log.py`, `test_ci_image_pin_population.py` (which also gained `*.yaml`), `test_remote_state_inventory.py` (folded onto the shared derivation), and `test_pr_changed_files.py` (not on the issue's list — found by sweeping the whole repo). ASSESSED AND RECORDED, not silently skipped: `_repo_copy` takes its file list from the index for hermeticity though it makes no completeness claim; `test_ci_dropped_step_guard.py` has no filesystem population at all; the decisions corpus is recorded as unexamined rather than cleared; and the SPA page-size guard is deferred to #819 with its obstacle documented. This is not "replace every glob". `scripts/tests/tracked_files.py` is the single derivation. `test_guard_populations_derive_from_git.py` proves it in two measured complements: exhaustive removal catches a hardcoded `.exists()` admit and memoisation; the call log catches an append-only source that yields nothing on this machine — #778's shape — which removal cannot see because it has nothing to remove. Twelve rounds of independent cold review, alternating model families in isolated worktrees. The production derivations were confirmed sound every round; every blocking finding after the first was in the proofs or in prose claims about them. Counts over growing populations were removed rather than corrected, after three drifted. fixes #806 Co-authored-by: Timothy <timothy@noreply.gitea.tblindustries.be>	2026-08-22 16:07:58 +00:00

Nine cold cross-family review rounds.

timothyandClaude Opus 5	7347a08979	fix(778): the 200-not-an-array arm had the same lying reason, one branch earlier ... Local review returned MERGEABLE — no Blocker, High or Medium, both sentinels verified pinned by mutation, no regressions. Its one Low is taken rather than deferred, because it is a one-line fix and because deferring it would leave exactly the shape this PR exists to document. A 200 whose body is NOT an array never reaches the classifier: the array gate diverts it, `bp_code` stays 200, and the generic ask then reported "HTTP '200' — Gitea unreachable, or these credentials lack the repo-admin scope" about a read that plainly succeeded. That is the identical defect the previous commit fixed for the throw-inside-the-classifier arm, one branch earlier — fixed where it was noticed, left in its twin. The previous commit's message even generalised the pattern ("a sentinel that doubles as an HTTP code makes a decision state a cause that did not happen") while covering only one of the two arms it applies to. The test is now parametrised over all three shapes that reach an unusable 200 — UNPARSEABLE-RULES, GARBAGE, EMPTY — and reverting the new sentinel reddens the two that the first fix missed. Also finishes the de-indent the previous commit claimed: that comment block went from 19 leading spaces to 6 while its siblings use 2, so the claim was true of the direction and not of the result. 729 tests green. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 22:50:23 +02:00
timothyandClaude Opus 5	3f0af38509	fix(778): pin the nomatch sentinel — it shipped unpinned, exactly like the guard before it ... Local review of the previous commit returned BLOCKED. Both findings taken; nothing pushed to CI while this was iterating. MEDIUM — the `nomatch` fix was entirely unpinned. Reverting both sites to `bp_code=404` left the suite 33/33 green, because no fixture ever emitted an HTTP 404 on the LIST read: the codes exercised were 000, 403, 500 and 200, and the old `NOT-FOUND` mode had been repurposed to return 200 with `[]`. So the defect that commit describes could be reintroduced silently — in a PR whose subject is unfalsifiable guards, one round after being blocked for precisely that shape. There is now a `LIST-404` fixture and a test; reverting the sentinel reddens two tests. The same class, one arm over and found while fixing it: a 200 whose `branch_name` is a number makes the classifier throw (`//` fires only on null/false), and that was mapped to `bp_code=000`, reporting "HTTP '000' — Gitea unreachable" about a read that plainly succeeded. It gets its own `unreadable-rules` sentinel and message, with a fixture and a test — reverting it reddens. The pattern across both: a sentinel that doubles as an HTTP code makes a decision state a cause that did not happen. The decision was safe each time; only the reason lied. MEDIUM — four comments still described 404-as-a-finding as live, contradicting the hook comment added in the same commit. The worst said a 404 means "this branch is entirely unprotected" in a test whose fixture now returns 200 with `[]`, which would have talked the next reader into re-adding the deny. Renamed that mode `EMPTY-LIST` so it says what it is. Also: the hook quoted a reason string it no longer emits; a stray over-indented line survived the de-indent; `bp_called` was write-only after its reader was removed. 727 tests green. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 22:09:16 +02:00
timothyandClaude Opus 5	7d81f85b38	fix(778): make the by-name pin falsifiable — it was filtering on the property it asserted ... Confirmation pass returned BLOCKED, and its lead finding is the one worth having. The test forbidding the by-name lookup recorded URLs from INSIDE the `endswith("/branch_protections")` branch, so the only URLs it could ever record were ones that already satisfied the assertion. A by-name request was invisible to the very test written to forbid it. Cold review proved it by reintroducing the lookup in the hook: the suite stayed 33/33 green. That is the filter-on-the-asserted-property defect this PR's sibling record exists to describe, committed inside the guard against it — and the commit message had called the twin "pinned so it cannot come back". The recorder now sees every branch-protection URL whatever its shape. Re-verified by the same mutation: reintroducing a by-name call reddens exactly the two tests that forbid it. Also from that pass: - an HTTP 404 on the LIST read reached the "the full rule list was read and none matches" deny — a claim about a read that never happened. Gitea answers 404 for a repo that is absent or invisible to the credential, so the classifier's own verdict is now the sentinel `nomatch` and HTTP failures reach the ask; - two comment blocks still described the deleted by-name endpoint as live, one of them asserting the classifier "is never reached at all"; - the decision record still documented `branch_protections/{base}` and its 404 semantics as the mechanism, in the record this PR authored — now rewritten to the list endpoint, with why reading the LIST is the load-bearing choice; - seven assertions on a string the hook no longer emits, and three test names/docstrings describing the removed 404 flow; - an unused fixture helper, and 79 lines left over-indented by the removed nesting. 724 tests green. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 21:29:09 +02:00
timothyandClaude Opus 5	f3863c3720	fix(778): delete the by-name lookup — the precedence check was guarding the dead path ... Final review returned MERGEABLE with no Blocker and no High. Its one Medium is taken, and it is my own recurring trap for the third time in this PR: fix one path, then check its TWIN. The hook looked a rule up by NAME first and enumerated the rule list only on a 404. But `branch_protections/{name}` is an exact DB lookup — `GetProtectedBranchRuleByName` — which performs no matching and knows nothing about precedence. A 200 from it means "a rule with this NAME exists and lists this context", never "this context is required on this branch". So the precedence argument added last round guarded the 404 path while the 200 path granted without it — and since this repo's rule IS named `main`, the by-name lookup always returns 200. The hardened code was dead and the unhardened code was live. Given a rule `main` requiring review-verdict/h10 and a rule `m*` with better Priority that does not, Gitea applies `m*`; the by-name hit on `main` saw h10 and granted anyway. Fixed by DELETING the twin rather than documenting it: one fetch of the full list, one classifier, one argument, no second path to keep in step. Two things fall out for free — the ref no longer reaches a URL segment, so the percent-encoding hazard is removed by construction rather than escaped (its test is replaced by one asserting no ref reaches the URL at all), and every case the classifier already covered now applies to the live path instead of an unreachable one. Verified against the live Gitea: the classifier returns `exact` -> rule `main` -> enable_status_check=true, h10 present. A new test pins that the precedence check runs even when an exactly-named rule exists, and asserts the by-name endpoint is never requested, so the split cannot come back silently. The grant string now states what was actually established — read from the full rule list, matched with Gitea's own plain-vs-glob split, refusing wherever precedence or folding is not derivable — rather than the stronger "confirmed required" it claimed while consulting a single named rule. 724 tests green. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 21:07:09 +02:00
timothyandClaude Opus 5	c7bea972d6	fix(778): close the last three residuals — ambiguous exact rules, non-ASCII folds, one unpinned test ... Confirmation review returned MERGEABLE at 356cddbb5, having independently re-executed every claim (the "2 -> 6 dead-classifier" figure exact, the "20 tests" trap figure exactly reproducible, the arm reorder pinned, live branch protection confirming the dated claim). Its three residuals are taken here. M1 — the backslash test hit the undecidable arm but asserted only `"ask" in reason`, which a CRASHED classifier also satisfies. Its two siblings got `"could govern it"` one commit earlier and this one did not. Under the dead-classifier mutation it was the single green test of that arm; now red. L1 — with two plain rules differing only in case, `first` picked LIST order while Gitea picks by Priority. Given `MAIN` requiring review-verdict/h10 and `main` not, the hook could inspect the rule that requires it and auto-grant on a base where Gitea enforces the other — the same defect as the arm order, one level down. Two fold-equal rules are now undecidable. L2 — the same standard, applied where I had waived it. The backslash paragraph rejects "nearly unreachable" as a standard for the arm that issues a DENY, and two paragraphs up the ASCII-only fold was accepted on exactly those grounds: rule `ünstable` and base `Ünstable` fold equal under Gitea's EqualFold and not under `ascii_downcase`, landing on `none` -> deny with a false stated cause. A non-ASCII rule name or base is now undecidable rather than fold-compared. The non-ASCII test is `explode | any(. > 127)`, not a `\uXXXX` regex: the first attempt was a character-class regex whose backslashes are ambiguous through a single-quoted shell string into jq, and a standalone probe showed it classifying plain `main` as non-ASCII. Codepoints have no escaping layer to get wrong. Both new arms are mutation-proven individually; an earlier attempt at those proofs used perl substitutions that silently matched nothing and reported green, which is why they were redone in python with an explicit assert on the target. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 20:23:32 +02:00
timothyandClaude Opus 5	356cddbb59	fix(778): pin the arm order, and correct a wrong explanation I had just written ... Two self-found defects while pre-empting the confirmation round's own questions. THE REORDER WAS UNPINNED. Swapping the classifier arms back to exact-first left all 29 tests green, so the previous commit's central change was invisible to the suite — an unproven change shipping under a green run. The missing fixture is the one that distinguishes the orders: a list holding BOTH an exactly-named rule that requires `review-verdict/h10` AND a glob rule that could also govern the base and does not. Exact-first inspects the rule that requires h10 and auto-grants; undecidable-first asks. Now mutation-proven in both directions. I HAD MISDIAGNOSED THE TRAP, and asserted the wrong cause in a comment. A three-line repro disproves "an EXIT trap suppresses output" — it does not. The real mechanism is that this file already owns its EXIT trap: `scripts/hook-fire-log.sh` installs `trap 'etv_hook_fire_end "$?"' EXIT` (#776), and in capture mode that handler is what REPLAYS the decision JSON to stdout. A second `trap ... EXIT` silently replaces it, so the decision is captured and never emitted. The trap slot is a single shared resource and the sourced library claimed it first. That second one is the shape this whole PR is about, committed against my own work: an explanation that fits the symptom, is written down as fact, and is wrong. It would have told the next person the construct is unusable rather than that the slot is taken. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 19:54:47 +02:00
timothyandClaude Opus 5	d8ff6fa229	fix(778): ask before trusting an exact rule, and make the tests tell classified from crashed ... Ninth cold review: MERGEABLE, no Blocker, no High. Its three Mediums taken anyway, because each was a one-line fix retiring the last "asserted rather than verified" surface in the file whose whole subject is that shape. M1 (backslash missing from the metacharacter class) was already closed in cd1b28637 — found independently while stress-testing the superset claim, in the window the reviewer was working against the previous head. M2 — the `exact` arm was not decidable. Gitea picks the governing rule with GetFirstMatched over a list sorted by Priority and THEN by plain-name-ness, so a glob rule with a better Priority outranks an exactly-named one. Preferring `exact` would inspect a rule Gitea might not be applying: if the exact rule requires `review-verdict/h10` and a higher-priority glob rule does not, the gate auto-grants on a base where the check is not enforced. `undecidable` is now evaluated FIRST, which makes the classifier sound without knowing the precedence rules at all — the only claim this code is entitled to make about somebody else's resolver. M3 — four tests could not distinguish "classified correctly" from "classifier crashed", because a dead classifier lands on the generic could-not-read ask and they asserted only `"ask" in reason`. Measured with the reviewer's method rather than argued: injecting `error(...)` at the head of the jq program left 2 of them red; the strengthened assertions leave 6. The glob arms now pin the text unique to the undecidable ask, and the decidable arms assert the rule was HONOURED rather than referred to a human. Also: the module docstring still described a three-arm contract after this change added a fourth; the inventory row still summarised the old two-way behaviour; the ASCII-only case fold is now stated as a deliberate under-match rather than as parity with EqualFold; the live-config claim is dated; and one jq call rejoined the file's `|| true` discipline. A `trap ... EXIT` for temp-file cleanup was tried and REVERTED: it suppressed the hook's decision output entirely and took 20 tests red. A gate that prints nothing is the one outcome it must never produce, so the tidier construct loses to the one that works, with the reason recorded where the next person will try it. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 19:47:06 +02:00
timothyandClaude Opus 5	cd1b286378	fix(778): backslash is a metacharacter too, or the none arm's proof does not hold ... Self-found while stress-testing the superset claim I introduced one commit earlier — the crux the new classifier's safety rests on. `none` authorises a DENY on the stated grounds that nothing can possibly govern this base, so its premise must hold unconditionally, not usually. The superset was "literal prefix + .* + literal suffix", which is sound for every glob dialect EXCEPT one case: gobwas/glob reads `\{` as a LITERAL brace, so a rule `a\{b` governs the base `a{b`, while a superset treating `\` as an ordinary character builds `a\.*b`, misses, and denies a base that is in fact protected. Verified before and after: with `\` outside the metacharacter class the classifier answered `none` for that pair; with it inside, `undecidable` -> ask. 18 adversarial rule/base pairs (brace alternation, negated and ranged classes, `**`, leading and trailing metacharacters, unicode, empty alternation) all answer `undecidable`, never `none`, so no dialect-matching case falls through the deny arm. Git ref rules make this nearly unreachable — a branch name may not contain `*`, `?`, `[` or `\` — but `{` IS legal in one, and "nearly unreachable" is not the standard for the arm that issues a deny. Checked with `git check-ref-format` rather than assumed. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 18:59:36 +02:00
timothyandClaude Opus 5	456042ee51	fix(778): stop claiming parity with Gitea's glob matcher — classify, or ask ... Eighth cold review: no Blocker, no High. Three Medium, two Low, one Nit. MEDIUM — the substantive one. The glob fallback asserted it matched rules "the same way Gitea applies them", and it does not. Gitea compiles a rule name with gobwas/glob and a `/` separator: its `*` does NOT cross a slash, `?`/`[…]`/`{a,b}` are wildcards, and a plain name is folded case-insensitively. Mine used `.*` for `*` and escaped the rest. The divergence has a false-OPEN direction — `release/*` does not govern `release/26/hotfix` in Gitea, but `release/.*` matched it here, which would auto-grant a scheduled merge on a base where the check is not required. That is #622's hole, reached through the block written to close it, via exactly the failure this PR records: a claim about an external system asserted rather than verified. Reimplementing somebody else's glob dialect would be a second copy of a parser, which this repo has already withdrawn a change for. So the classification is three-way and each arm is safe WITHOUT knowing the dialect: an exact non-glob name folded case-insensitively is decidable; a glob rule that could govern the base is UNDECIDABLE and asks; and "could" is tested with a provable superset of any glob dialect — literal prefix, `.*`, literal suffix — so if even that cannot match, no dialect can. Over-matching would grant on unestablished protection; under-matching would deny with a false cause. Asking is the only answer honest in both directions, and it is rare: this repo's rule is the plain name `main`. MEDIUM — a count that was wrong the moment it was written ("46 of the 69 rows are N/A"; it is 44). It was added by the same commit that demoted two rows. That is the FOURTH stale number in this change, in the deliverable whose own record argues against hand-maintained counts. Removed rather than corrected, with the reason stated. MEDIUM — `migration-smoke.sh` still said "Same shape" as `security-scan.sh`, whose note had just been rewritten to the opposite conclusion, so the backreference had silently inverted. It is the same pull-then-run over a mutable tag and deserves the grade MORE, not less: `security-scan.sh` boots a throwaway container and authorizes nothing, while this gates a production stack recreation. Regraded. LOW/NIT: an `end <= start` guard that `str.index(…, start)` makes unreachable by construction is replaced with the reachable failure it was describing; a docstring still named a fixture from an earlier draft; a reflowed `#707.` was line-initial. Two mutations were ineffective on the first attempt — one left the `decide ask` continuation in place, the other had no test covering case-folding. Both redone; each arm now reddens a named test.

timothyandClaude Opus 5	7db4101b24	fix(778): the escape emitted TWO backslashes, turning a false-open into a false DENY ... Seventh cold review. One High, one Medium, three Low, seven Nit — all in the two newest commits, which is where every round of this PR has found its defects. HIGH, and it is my own fix from the previous commit. In jq source `"\\\\"` decodes to TWO backslashes, so escaping produced `\\.` — "a literal backslash, then any character" — instead of an escaped dot. Every rule name containing a metacharacter became UNMATCHABLE, and a rule named `a[b` crashed jq outright (swallowed by `|| true`). Verified: `release/26.*` no longer matched base `release/26.4`, so the fallback found nothing and hard-DENIED with the stated cause "has NO branch protection at all" — converting a false-open into a false deny, which the block's own comment calls the worse outcome. One character: `"\\" + .c`. Correct across 14 rule/base pairs. WHY MY TEST MISSED IT, which is the transferable part: it asserted only the NEGATIVE direction (`mai.` must not match `main`). A rule matched literally and a rule made unmatchable both fail to match the wrong base, so the assertion passed for the wrong reason. Only a rule that SHOULD match separates them, and there was no positive control. There is now — plus a char-class case — and both go red against the over-escaped version. That also needed a base containing a dot: a rule cannot carry a metacharacter and still match `main`, so the first attempt at the positive control was unsatisfiable by construction. MEDIUM — four live claims that the population "derives from the filesystem", left standing by the commit that replaced that mechanism: the guard's own docstring 45 lines above a comment shouting the opposite, the inventory heading 21 lines under "Every git-tracked file", the docs/README entry, and — worst — the record's `mechanics:` frontmatter, which is the copy the catalog and MemPalace mirror, so discovery would have returned the superseded lesson. All corrected. LOW/NIT: the URL-encoding test grepped the source for `@uri` (it now asserts the URL actually requested, and reddens when the encoding is removed); the hoist comment said "every path below" without noting the docs-only enumeration above it (bounded — that path is a passthrough to a human prompt, never a grant); a now-unreachable guard is annotated rather than left reading as live; `issue-qualification-audit.sh` was `N/A` while `select-queue.sh` was `UNSAFE-KNOWN` on the same argument, and `security-scan.sh` claimed "one step" for a pull-then-run over a mutable tag — both regraded; the `PINNED` definition now says what separates its second shape from an `N/A` "one step" row (the identifier's immutability, not the step count); the section parser raises a message naming both required headings instead of a bare ValueError; and the record's body is rewrapped.

timothyandClaude Opus 5	01de6cbd8b	fix(778): * is the only wildcard — a rule name's regex metacharacters were live ... Found by attacking my own glob fallback from the previous commit before the reviewer got to it, which is the round where this PR's defects have landed every time. The 404 fallback matched a branch-protection rule by substituting `*` into a raw regex, leaving every other metacharacter active. Verified directly: a rule named `main.x` matched the base `mainax`, and `a+b` matched `aab`. The direction is the one that matters — a spurious match to some OTHER rule that happens to require `review-verdict/h10` reports this base as protected when nothing governs it, so a consent gate answers yes on evidence about a different branch. Each literal segment is now escaped before the pattern is assembled, so the wildcard survives and nothing else does. Verified across 11 rule/base pairs: metacharacters are literal, `*` still spans, exact and non-matches unaffected. The regression test needed two goes to stop being vacuous, both times for the same reason the rest of this PR keeps hitting: the stub never 404'd for the new mode, so the run denied earlier via the by-name lookup and never reached the fallback at all. It now goes red against the unescaped predecessor. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 18:01:42 +02:00
timothyandClaude Opus 5	4261f76dd2	fix(778): derive the population from git, not the disk — the guard was red on every dev checkout ... Sixth cold review (a different reviewer, in-repo, worktree-isolated after the cross-family runs wedged twice on their sandbox). One High, one Medium, two Low, two Nit. All fixed. HIGH, and it is the third time this population has been wrong. `rglob` is recursive, so it also enumerated `.husky/_/` — 17 husky shims generated by `npm ci` via web/package.json's `prepare`, gitignored and untracked. The guard therefore derived 76 files against a 59-row table and was RED on every checkout that has run `npm ci`, while staying GREEN in CI, whose `script-tests` job checks out and pip-installs but never runs `npm ci`. A guard that fails everywhere except where it runs is the fastest possible route to "that test is always broken, ignore it" — on the artifact whose entire thesis is population correctness. Reproduced, then fixed at the source rather than with a fourth traversal patch: the population now comes from `git ls-files`. The index is authoritative, identical for CI and every checkout, and excludes untracked build output by construction instead of by an exclusion list someone must maintain. That is what this PR's own record says to do; the first three attempts each derived from whatever happened to be on disk. Three tests go red against the rglob predecessor. MEDIUM — twin-missed, in the fix from the previous round. Round 4 re-read the base before the branch-protection lookup, inside the scheduled branch only, leaving the #632 retarget DETECTION still reading the top-of-hook snapshot. The reviewer demonstrated it with this PR's own fixture: scheduled+retarget denied while immediate+retarget AUTO-GRANTED. The re-read is now hoisted above every base-dependent consumer, so one read serves both paths, and the duplicate is gone. Note for the record: the hoist is the load-bearing part — once `live_base` is fresh, #632's own comparison catches the retarget too, so the explicit deny only bites when no verdict records a base. The tests are scoped to exactly that case, because as first written they passed under mutation. LOW — a 404 from `branch_protections/<ref>` does not prove the branch is unprotected. Gitea keys that endpoint on the RULE name, so a base covered by a glob rule 404s while being fully protected, and an unencoded ref containing `/` (`release/26.4`) 404s because the path is malformed. Both produced a hard deny stating a specific, false cause — and a deny blocks outright rather than prompting. The ref is percent-encoded, and a 404 now consults the rule list before denying; an unreadable list asks. LOW/NIT — the scope prose attached the extension restriction to `scripts/` alone while the guard applied it everywhere (a `.py` hook would have joined the described scope and acquired no row); `.yaml` workflows are now in scope too. The `PINNED` definition required re-validation, which two legitimately-pinned rows do not do because their check and use are one step over an immutable event-payload sha. Row ordering restored. And once more, the recurring one: adding a scope TABLE to the doc made three prose rows parse as inventory sites — the parser reading its own documentation as data, the same defect as the UNSAFE-KNOWN check that once parsed the paragraph defining UNSAFE-KNOWN. Row parsing is now bounded to the inventory section explicitly. refs #778 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-08-19 17:53:25 +02:00
