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.

docs/ — task-signal map

Purpose: route a fresh contributor/agent to the minimal set of docs for the task at hand, instead of a mandatory front-to-back read. Update this doc in the same PR that adds, removes, or retitles a doc below, or that changes which sections a task signal points to.

Start here, always

  • CLAUDE.md (repo root) — project intro: architecture, layout, dev commands, conventions, Task Completion Protocol.
  • docs/contributing.md — established code patterns (CQRS/MediatR, LanguageExt, the ChicoryTV SPA, EF Core dual-provider migrations, FFmpeg pipeline, analyzers, testing). Read before any non-trivial change.

Task signal → minimal sections

Knowledge retrieval (MemPalace + catalog + Gitea)

These four rules are the seam agreed with server-management#642 (the Gitea→MemPalace exporter). They apply whether the question comes up via MemPalace, a grep, or a stale comment:

  1. Current conventions/decisions → catalog-first. Start at docs/decisions/README.md; discover via the ErsatzTV-Decisions wing (active) / ErsatzTV-Decisions-Archive (superseded/retired). Resolve by topic/key, never by chasing a file path.
  2. Issue history → evidence, not authority. The Gitea-ErsatzTV wing is historical narrative that may be stale; it never overrides current Markdown.
  3. The breadcrumb rule (the crux behavior change). A file path named inside a historical issue comment (e.g. "grep docs/decisions.md 2026-07-17", "see …") is a breadcrumb, not a live pointer. Find the current rule via the catalog / active wing by concept; do not treat the named path as current. (Why it's safe: still-current → in the active wing, breadcrumb resolves; superseded → the active wing returns the successor and a literal follow lands on a record that announces its own status: superseded; retired → the active wing returns nothing, which is itself the signal. The validator-enforced move-to-archive/ is what prevents the catastrophic "superseded rule read as current" case.)
  4. Fallback when MemPalace is stale/down: docs/decisions/README.md catalog, then rg '^`key: <dotted.key>`' docs/decisions/. MemPalace is never authority nor sole fallback.

MemPalace is candidate discovery only — every passage is verified against its cited Markdown/Gitea source before use. Never derive live queue state from MemPalace, #237, or historical comments; queue state is live Gitea state, retrieved via scripts/select-queue.sh (see docs/handoffs/chicorytv-issue-queue.md). Full retrieval contract (altitude/precedence, staleness bounds, what's mined per issue): docs/handoffs/chicorytv-issue-queue.md → "Knowledge retrieval".

  • docs/decisions/records/<area>/<topic>.md — one active decision record per file, YAML frontmatter (key/title/status/since/supersedes/superseded-by, plus optional stale-after/sources — ersatztv#603), rationale prose in the body. The filename is the key, so one-active-record-per-key is a filesystem property (ersatztv#610). docs/decisions.md and the topic files remain as the lifecycle-schema narrative plus a "Records formerly in this file" index, which is what keeps older date-based pointers resolvable. Generated active view: docs/decisions/README.md (catalog / task router) — start there. Superseded/retired records live in docs/decisions/archive/ and are read only for history, never for "what is the current rule."

Queue state is live Gitea state, retrieved each session via scripts/select-queue.sh — see that file's standing kickoff for the two concurrent tracks (orientation ‖ selection). ersatztv#237 is a closed, archival historical tracker (superseded by startup.parallel-orientation in docs/decisions.md) — not a live pointer.
