timothyandClaude Opus 4.8 bad19f8d26 fix(473): review fixes — only a redirected 404 fails closed
Adversarial review of PR #479 found the stated fail-open contract was not
what the code measured, plus four smaller gaps. All fixed here as a
follow-up commit (no amend/force-push).

High — a 404 from ErsatzTV's OWN endpoint was treated as "media gone".
/media/{provider}/... is served by InternalController, which returns
NotFound when the media source is unconfigured or momentarily missing
(a media-source edit that deletes+reinserts connections, a restore, a
partially-configured server). Probing for "any 404" therefore failed
CLOSED for every item on that source -- exactly the case the fail-open
contract exists to prevent. A media-server 404 always arrives after a
redirect, so an un-redirected 404 is now treated as available.

Medium — the new switch label was untested and its benefit overstated.
maybeDuration/finish are computed before the switch, so `default:`
already sized the error card to the next playout item; the label only
changes the caption. The handler test asserted call counts only, so
deleting the label still passed. It now asserts the error message, and
removing the label fails the test (verified).

Medium — Plex/Emby branches changed but had no coverage. Added an Emby
handler test asserting the probe is called with the emby URL.

Low — caller cancellation was swallowed and pinned as desired behaviour.
A shutdown / client disconnect is a genuine signal, not a probe failure;
it now propagates, and only the probe's own 2s timeout fails open.

Low — the response stream was disposed unread, aborting the connection
instead of returning it to the pool. The one requested byte is drained.

Nit — fully-qualified RangeHeaderValue replaced with a using.

docs/decisions.md corrected where it overstated: the switch label's role,
the "fixes the class for all three media servers" claim (external-JSON
channels bypass ValidatePlayoutItemPath entirely -- filed as #480), and
the unmeasured latency assertion. Deferred HEAD-instead-of-GET recorded
with its reason rather than silently dropped.

docs/ — reading order

Purpose: index of docs/ so a fresh contributor/agent knows what to read and in what order. Update this doc in the same PR that adds, removes, or retitles a doc below.

Read in this order at session start:

  1. CLAUDE.md (repo root) — project intro: architecture, layout, dev commands, conventions.
  2. 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.
  3. docs/domain-model.md — what the app IS: entity glossary, channel→playout→schedule/block concept map, where each concept is edited in the SPA.
  4. docs/api-conventions.md — checklist for adding/changing a /api/* endpoint (controllers, DTOs, error mapping, auth, OpenAPI regen, tests).
  5. docs/spa-conventions.md — playbook for adding a screen to the ChicoryTV React SPA.
  6. docs/e2e-local.md (+ scripts/e2e-local.sh) — how to run a live local instance for manual or Playwright-MCP verification.
  7. 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.
  8. 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.
  9. docs/decisions.md — append-only "why" log. Check here before challenging an existing convention. Start from its Index, which links the four topic files under docs/decisions/ (large same-topic clusters) and lists the remaining in-file entries.
  10. docs/ci-cd.md — build/test/release pipeline, versioning, dependency management.

Also present in docs/:

  • 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/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 (goal, arc, what's in flight/next) lives in the pinned Gitea tracker ersatztv#237 — read that, not this file, for current state (protocol: decisions.md 2026-07-11).
  • docs/handoffs/rest-api.md — original handoff prompt for kicking off the REST API work (#2).
