The six plain-bool lock flags (Plex, Trakt, Emby/Jellyfin/Plex collections, troubleshooting playback) used a non-atomic check-then-set, so two concurrent Lock* callers could both win. Convert them to int flags mutated only via Interlocked.CompareExchange, so the caller that wins the 0->1 transition is the sole owner and the only one that fires the change event. The three ConcurrentDictionary-backed kinds (Library/Playout/RemoteMediaSource) were already atomic; drop their redundant ContainsKey pre-checks. Define the ownership contract (tokenless single-owner discipline, no interface change) on IEntityLocker and in docs/decisions.md: a true from Lock* confers ownership of exactly one release; Unlock* on an unlocked slot returns false, fires no event, and logs a warning (the double-release / non-owner tripwire). Adds EntityLockerTests (real locker, parallel-caller races) proving exactly one winner per kind, one-releaser-per-slot, and event-fires-once-per-transition. Ref #231. Scan-lifecycle call-site fixes that consume this contract land in the same PR (#232); the BuildPlayout/subtitle finally-gating is #234.

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:
CLAUDE.md(repo root) — project intro: architecture, layout, dev commands, conventions.docs/contributing.md— established code patterns (CQRS/MediatR, LanguageExt, Blazor/ MudBlazor, EF Core dual-provider migrations, FFmpeg pipeline, analyzers, testing). Read before any non-trivial change.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*.Testsproject /websuite covers, golden-file nets, the timezone-independence rule, how to run subsets, the per-PR verification gate.docs/blazor-route-parity.md— the #91 phase (b) tracker: which Blazor routes are redirected, SPA-ready-but-not-redirected, or still Blazor-only (and which issue blocks each).docs/decisions.md— append-only "why" log. Check here before challenging an existing convention.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 bydocs/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 byscripts/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).
