fix(778): round 3 — fix the overclaim I left in the code, and defer the pre-existing ones to #803
Fourth cold review: no Blockers, 2 High / 2 Medium / 2 Low. It independently
re-derived the population (59 files, 59 sites, 69 rows, 3 PINNED) and verified every
numeric and factual claim in the diff, including the corrected confinement rationale.

THE ONE THAT STINGS. The grant reason string still said a commit pushed before Gitea
merges "will clear it and block the merge" — the exact sentence the new decision
record quotes as THE overclaim this issue exists to remove. I documented it in three
files and left it in the code a human actually reads. It now states the guarantee and
its condition: the required check was confirmed rather than assumed, and it holds
while that branch protection stands.

FIXED HERE (all in files this PR already touches):
- enable_status_check is validated as a BOOLEAN. `"true"` is not `true`, and comparing
  the string to `true` produced a confident deny from a payload never understood —
  the tri-state collapsing to two, the same defect as the contexts shape one line down.
- `.statuses` members are validated, not just the array (see the honest caveat below).
- the docs-reminder N/A rationale said "the job cannot fail and never reaches the
  combined status", which is false — any job's status joins the combined state. The
  true, narrower reason is that its fetch and diff are failure-swallowed, so the
  remote read can only change the warning's wording.
- docs/README names the scripts/tests exclusion in BOTH statements.

A VACUOUS TEST, CAUGHT BY ITS OWN MUTATION PROOF. The regression case for the
`.statuses` member validation stays GREEN against the predecessor: the #632
base-retarget block runs first and already validates every member it consumes, so it
catches the payload before the scheduled branch is reached. The two guards overlap —
duplicate guards masking each other, again — which makes that finding LATENT, not
live, and my added clause defence-in-depth rather than a fix. The test now asserts the
observable contract (a decision is always emitted) and says plainly that it is not a
mutation proof of the newer clause. Shipping it as one would have been the exact
grade inflation round 2 rejected.

DEFERRED to #803, with the reason stated rather than implied: a head-ABA
(force-push H1 -> H2 -> H1 during pagination) defeats pr-changed-files.sh, and three
OLDER contracts still assert more than the new inventory rows do. That residual
predates #778 and lives in #707's mechanism; correcting another active decision
record inside a PR already at four review rounds is how a scoped change stops being
reviewable. The inventory rows are accurate today and now point at #803.

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

Signal Read
Session startup / "what's next" (no issue named) docs/handoffs/chicorytv-issue-queue.md (standing kickoff — two concurrent tracks: orientation ‖ scripts/select-queue.sh 5)
Named-issue pickup Skip queue selection; go straight to focused retrieval — see "Knowledge retrieval" below, then the issue body
Adding/changing a /api/* endpoint docs/api-conventions.md checklist + docs/endpoint-index.md
Adding a ChicoryTV SPA screen docs/spa-conventions.md
Scheduling / playout engine work docs/domain-model.md + decisions catalog rows keyed sched.* (docs/decisions/README.md)
Concurrency / optimistic-locking work docs/api-conventions.md §7a/b/c + docs/decisions/optimistic-concurrency.md
Auth / security-surface work docs/decisions/api-auth-security.md
CI / release pipeline work docs/ci-cd.md + docs/decisions/release-ci-governance.md
Proposing a new guard / CI check / regression test convention docs/defect-shapes-773.md §4 (detector menu + the classes where no detector is plausible), then the two rules every guard must satisfy: docs/decisions/records/testing/guard-derives-population-from-source.md and …/guard-ships-with-mutation-proof.md
Adding / changing / deleting a guard file docs/guard-inventory.md — every guard's row is machine-checked by scripts/tests/test_guard_inventory.py, so a new guard must acquire a row before the suite goes green
Writing code that reads live Gitea/remote state and then acts on it docs/decisions/records/process/check-and-use-pins-a-version.md, then docs/remote-state-inventory.md — a new executable under scripts/ (excluding scripts/tests/), .claude/hooks/, .husky/ or .gitea/workflows/ must acquire a row there before scripts/tests/test_remote_state_inventory.py goes green
Finding every site that references a symbol (multi-site fix/sweep) docs/local-lsp-tooling.md — which surface answers, and why a delegated agent must be pointed at the csharp-lsp MCP tools rather than the LSP tool
Live local run / Playwright-MCP verification docs/e2e-local.md + scripts/e2e-local.sh
Adding/changing a UI-E2E browser flow docs/e2e-local.md → "UI-E2E harness" + scripts/e2e-ui.sh
What does a test suite cover docs/testing.md
Legacy Blazor route lookup docs/blazor-route-parity.md (historical #91 phase (b) inventory)
"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/local-lsp-tooling.md — the code-intelligence surfaces (the LSP tool's three servers and the csharp-lsp MCP server): how each is configured, which one a subagent can actually reach, the traps (a cold server answers the first query with a confidently partial result), and scripts/check-local-lsp.sh to verify the preconditions. Read before briefing an agent to find every site referencing a symbol.
  • 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/defect-shapes-773.md — root-cause analysis of the recurring defect shapes across the whole closed-issue corpus (#773): the measured class ranking, the four families they consolidate into, the cheapest mechanical detector per class, the classes where no detector is plausible, and an audit of which configured hooks/MCP servers/LSPs are actually invoked. Read it before proposing a new guard or CI check — §4 is the detector menu, and it argues against enumerating cases one incident at a time.
  • docs/remote-state-inventory.md — every executable in scripts/ (excluding scripts/tests/), .claude/hooks/, .husky/ and .gitea/workflows/ that reads live remote state and acts on that read, classified PINNED / CAS / UNSAFE-KNOWN / N/A with the window and what bounds it. Code outside those directories — C#/TypeScript guards, web/, and the test suites themselves — is out of scope, and the doc states that rather than implying coverage. The population is derived from the filesystem and compared for set equality by scripts/tests/test_remote_state_inventory.py, so a new script that talks to a remote service cannot ship unclassified. Read it with process.check-and-use-pins-a-version; it is that record's detector, since the class has no plausible linter (docs/defect-shapes-773.md §4 detector D).
  • docs/guard-inventory.md — every executable guard file, what it blocks, whether it is a GUARD or TOOLING, and whether it ships a mutation proof (MUTATION / BEHAVIOUR-ONLY / NONE) with a file::function ref. The population is derived from the filesystem and the workflow/hook call sites and compared for set equality by scripts/tests/test_guard_inventory.py, so a new guard cannot ship unclassified and a renamed test cannot leave a row claiming coverage it has lost. Guards implemented inline in workflow YAML are deliberately outside that population — the doc states the limit rather than implying coverage.
  • 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).
