fix(651): make the stated invariant true on Playlists; pin the predicate's endpoints
The review's headline finding was in my prose, not my code: spa-conventions and the round-8
commit both claimed an unbindable id "surfaces as 'no selection' with Save disabled" and that
regressions "assert zero writes are reachable". True on RerunCollections and FillerPresets.
False on PlaylistsScreen in all three respects — `draftFromItem` nulled the id but KEPT
`selectedName`, so the row read "Cool Movie" over a null draft; Save had no selection check;
and clicking it did issue the PUT with `mediaItemId: null`. Only the server's
`ReplacePlaylistItemsHandler` 422 stood there, and the DB would have persisted it
(`PlaylistItemConfiguration` marks all four FKs `IsRequired(false)`).

Rather than weaken the claim, made it true: a dropped id now clears its label, and Save is
gated on every item having a selection, with a visible count as the reason.

`playlistGroupId` was the same class on the same screen — seeded from the wire into
`AddPlaylistDialog`, re-parsed with a bare `Number()`, and POSTed as an entity reference — so
"every path by which an id from the wire becomes editor state" was not literally true. Now
filtered from the group options and normalized on submit.

Added `selectionId.test.ts`. The predicate had become the single point of failure for eleven
call sites across three screens while being exercised only indirectly; nothing pinned the
inclusive endpoints, so a `>` for `>=` slip passed the entire suite. Verified by mutating
each comparison. Also documented why `0` and negatives are accepted — the contract is
bindability, not existence — because every other id check in this repo uses `id > 0` and the
next reader would otherwise "fix" the inconsistency.

Two of my assertions were vacuous, the eighth of that shape on this branch: one clicked a
button it had just asserted disabled (a restatement of `toBeDisabled()`), and one asserted a
POST count on a path that never attempted a save. The first is deleted; the second now
actually attempts the write, which makes it fail against the unguarded parent.

Corrected claim: all five round-8 regressions do fail against their parent, but on their
load-bearing assertions (`getByText('A selection is required')`,
`queryByText('Bogus Collection')`) — not on the write-count ones, which were passengers.

Follow-up filed as #677 (ScheduleItemInspector's unguarded ingresses; list-backed pickers
dropping malformed options silently).

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".

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).
