Added ChannelId to PlayoutNameViewModel and all 6 construction sites
(Mapper, GetPlayoutByIdHandler, and the Update{,Scripted,ExternalJson,Sequential}
PlayoutHandler commands), plus the list DTO PlayoutListItemResponseModel and the
PlayoutController list projection. Regenerated OpenAPI (v1.json) and the TS client
(v1.d.ts); endpoint-index.md unchanged (no endpoint/operation delta). Simplified
PlayoutsScreen resetSelectedChannel to key directly on selectedSummary.channelId
instead of resolving via channelStates. Updated controller + SPA tests.

Task 3 of ersatztv#71 (reshuffle-playout). Appends Seed as the last
positional field on PlayoutNameViewModel, threading it through the
Mapper list projection, GetPlayoutByIdHandler detail projection, and
the four Update*PlayoutHandler VM constructions, then exposing it on
PlayoutListItemResponseModel/PlayoutResponseModel via the controller's
ToResponse/ToListItemResponse mappers.
ChannelControllerTests.MakePlayout was an additional construction site
not listed in the task brief (positional-record break); updated to
append 0 for Seed alongside the brief's ErsatzTV.Tests changes.

Complete the #253 optimistic-concurrency contract's cross-editor ETag
rotation tail. The non-If-Match config siblings mutated editor-visible
state without bumping Version, so a concurrent editor of the same root
never invalidated. Now the Collection Add*/Remove handlers bump
Collection.Version, and UpdateCollection / UpdatePlayout / the three
ScheduleFile writers (which already force-wrote past a concurrent bump)
now bump too — all via SaveChangesForcingVersion (no If-Match → force
write, never 412/500).
No-op idempotence (Fable-caught trap): these gate reindex/BuildPlayout
fan-out on SaveChanges()>0, so an unconditional bump would fire spurious
rebuilds on an idempotent re-add / same-value re-submit. Each now
short-circuits a genuine no-op before the bump — Add handlers by an
explicit membership check (also fixing a latent duplicate-CollectionItem
insert), scalar writers by ChangeTracker.HasChanges().
Corrects #269's framing: the Add*ToCollection family is not
repository-mediated (IMediaCollectionRepository is read-only); each
handler writes via its own dbContext, so the scanner's separate
membership path is unaffected (a background scan does not rotate the
editor ETag).
Tests: CollectionEtagRotationTests + PlayoutScheduleFileEtagRotationTests
(rotation, no-op-without-bump-or-rebuild, force-write-past-concurrent-bump),
no-op guard proven non-vacuous by inverting the membership check.
Docs: api-conventions §7a + decisions.md. No new status codes / no
OpenAPI change (these endpoints take no If-Match, never 412).
The #265 RFC-7232 If-Match parser refinement is a separate PR.

Adversarial review caught a HIGH the fan-out introduced: activating Version as an
IsConcurrencyToken on Playout/Collection makes EF append `WHERE Version=@orig` to
EVERY root UPDATE, so a non-If-Match writer that saves via plain SaveChangesAsync
now throws DbUpdateConcurrencyException → 500 when a replace-all editor bumps the
row between its load and save. Realistic two-tab trigger (edit playout settings while
editing its alt-schedules; edit a collection's name while reordering) — a new crash,
previously silent last-write-wins.
Fix: shared ConcurrencyExtensions.SaveChangesForcingVersion — on a concurrency
failure it adopts the stored token as original+current (client-wins merge scoped to
the token, never reverting the concurrent bump) and retries, i.e. Phase-1 force-write
semantics for a missing If-Match. Applied to the exposed UPDATE writers:
UpdatePlayout, Update{Sequential,Scripted,ExternalJson}Playout, UpdateOnDemandCheckpoint,
UpdateCollection. Non-vacuous test proves the write lands and the bump survives.
Deletes + repo-mediated Add* writers (rarer / join-rows-only) re-scoped onto #269.

Backend mutation-hardening cluster from the 2026-07-11 mutation-safety audit
sweep (adversarial-reviewer #22/#23), the parallel-safe backend-isolated slice.
audit#22 F4 — standardize post-commit enqueues on CancellationToken.None:
20 command handlers under MediaCollections/, ProgramSchedules/, Playouts/,
Channels/ threaded the request cancellationToken into work that runs AFTER
SaveChangesAsync commits (WriteAsync rebuild/refresh enqueues, mediator.Publish,
reindex, cache Refresh, and post-commit lookups that gate an enqueue). A late
client-disconnect then turns an already-durable commit into a thrown request AND
drops the side effect. Generalizes the #251 deco-handler fix. Excludes
BuildPlayoutHandler (worker/background token, not a client-disconnect token),
the config/FFmpeg multi-upsert handlers (partial-commit case, separate
follow-up), and response-projection reloads (correctly keep the request token).
audit#22 F2 — DeleteChannelHandler/DeletePlayoutHandler now delete the channel
guide {number}.xml through IFileSystem.File.Delete (observable under
MockFileSystem) and BEFORE the commit (a post-commit delete orphans the xml on a
crash; the xml is regenerable on demand, so pre-commit delete is the safe order).
audit#23 F4 — ReplacePlayoutAlternateScheduleItemsHandler rejects an empty item
list in the handler (not only the controller pre-guard) so a direct caller can't
trip the Max()-on-empty crash.
Docs: api-conventions.md §7a (post-commit token convention + boundaries),
decisions.md entry (rationale, sweep scope, #253 PR2-4 coordination note).
Tests: guide-cache-delete-through-FS for both delete handlers, empty-list guard.

Adds per-playout REST for classic-playout alternate schedules and
block-playout templates, plus the default-deco read-side deferred from S3:
- GET/PUT /api/playouts/{id}/alternate-schedules (Classic only; 422 otherwise)
- GET/PUT /api/playouts/{id}/templates (Block only; 422 otherwise)
- PlayoutResponseModel gains decoId/decoName (GetPlayoutById includes Deco)
PUT assigns Index from array order (top = highest priority, last = catch-all
default), mirroring the Blazor editors. Alternate-schedule PUT requires a
non-empty list and existing ProgramScheduleIds; template PUT requires existing
TemplateIds and any supplied DecoTemplateId. Regenerates the OpenAPI spec.
