fix(698): review round 2 — close a PRE-EXISTING SIGPIPE inversion, narrow the bot allow-list, correct two overclaims
Cross-family adversarial review returned BLOCKED with 3 Blockers + 2 Highs. Two
were verified independently before acting on them.

BLOCKER 1 (pre-existing on main, not introduced here). `producer | grep -q…`
inverts under `set -o pipefail`: grep exits at its first match, the producer takes
SIGPIPE and exits 141 once the list exceeds the pipe buffer, so a MATCH is reported
as a FAILED pipeline. Reproduced at 1901 paths / ~171KB, inside the enumerator's
2000-file cap:
  * `A.cs` + 1900 docs paths  -> docs_only=yes, status 141 (a C# PR exempted)
  * `.gitea/…` + 1900 docs    -> the PROTECTED guard MISSES entirely
The second reaches a green required status on a PR rewriting the gate, with no
retarget, no bot account and no forged status. This construct shipped with the
original docs-only check (review-verdict.yml:257 on main), so it was live. Fixed in
both the enforced gate and the advisory hook by using here-strings, which have no
writer to signal. New record `ci.grep-q-pipefail-inversion`.

BLOCKER 2 (mine). `web/package.json` / `web/package-lock.json` are removed from
BOT_MANIFESTS. renovate.json enables only nuget/github-actions/dockerfile, so npm is
unmanaged here and the entry bought nothing — while package.json `scripts` are
EXECUTED by CI (npm ci, npm run build). It widened an exemption onto a
code-execution path for no benefit.

BLOCKER 3 + HIGH (documentation was wrong, code unchanged). The claim that `edited`
made the retarget residual "non-durable" is retracted: runs are not serialized, so a
stale run can post `success` after the reclassifying run posts `pending`. The ABA
transition is narrowed and observable, NOT closed. Likewise the provenance check
asks "posted by a user credential", not "posted by a reviewer" — ETV_STATUS_AUTH is
basic auth, so a #697 forgery gets a non-null creator AND an attacker-chosen
description and is preserved as human. Both now stated at full strength.

TESTS. 4 large-input cases crossing the pipe buffer, each paired with a large-input
POSITIVE control so "large lists now fail closed" (a deadlock) cannot pass as a fix.
Verified by mutation: reverting the here-strings turns all three negatives red while
the control stays green. Two of my own weak tests fixed — the "base advances" case
called head_moves_to(SHA) with the already-current sha (a duplicate positive control,
now a structural assertion that the comparator is .base.ref and never .base.sha), and
the arity test counted five arguments without checking the fifth was the base.

The whole class was invisible because every previous test used a handful of short
paths: a guard whose behaviour depends on a buffer threshold needs a test that
crosses it.

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

"Why do we do X this way" / challenging a convention Catalog-first: docs/decisions/README.md (active rows) → follow the row's link to docs/decisions/records/<area>/<topic>.md for full rationale. docs/decisions/archive/<area>/ only for "what did the rule used to be."

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".

Also present in docs/

  • docs/domain-model.md — what the app IS: entity glossary, channel→playout→schedule/block concept map, where each concept is edited in the SPA.
  • docs/api-conventions.md — checklist for adding/changing a /api/* endpoint (controllers, DTOs, error mapping, auth, OpenAPI regen, tests).
  • docs/spa-conventions.md — playbook for adding a screen to the ChicoryTV React SPA.
  • docs/e2e-local.md (+ scripts/e2e-local.sh) — how to run a live local instance for manual or Playwright-MCP verification.
  • docs/testing.md — testing map: what each *.Tests project / web suite covers, golden-file nets, the timezone-independence rule, how to run subsets, the per-PR verification gate.
  • docs/blazor-route-parity.md — historical record of the completed #91 phase (b) cutover: the Blazor Server UI is removed and every legacy route now 302-redirects to its SPA equivalent (or falls through to the catch-all → /app). Read it for the full legacy→SPA route inventory.
  • 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."
  • docs/ci-cd.md — build/test/release pipeline, versioning, dependency management.
  • docs/rest-api.md — REST API design doc for ersatztv#2 (goals, conventions, per-slice plan). Largely superseded day-to-day by docs/api-conventions.md; read this for the original rationale.
  • docs/mcp.md — the ErsatzTV.Mcp stdio JSON-RPC MCP server (#58): how it wraps /api/v1 as read + cautious-write tools, its config/env vars, auth, security posture, and the tool catalog.
  • docs/channels.md — Channel entity field reference.
  • docs/m3u-xmltv.md — M3U/XMLTV generation overview (ChannelPlaylist, GetChannelGuideHandler).
  • docs/fork-strategy.md — divergence policy vs upstream ErsatzTV.
  • docs/design-sync.md — Claude Design ↔ repo screen workflow (#92).
  • docs/endpoint-index.md — generated REST endpoint index (method/path/operationId/summary per OpenAPI tag). Do not edit by hand; regenerated by scripts/generate-endpoint-index.py / scripts/update-openapi.sh.
  • docs/handoffs/chicorytv-issue-queue.md — static session kickoff prompt + workflow lore. 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.
  • docs/tracker-retrofit-triage-237.md — audit trail for the #524 triage of ersatztv#237's 111 comments (method, per-comment classification, totals). Evidence for the docs.tracker-comment-retrofit decision; read it only when triaging another over-cap tracker.
  • docs/handoffs/rest-api.md — original handoff prompt for kicking off the REST API work (#2).
