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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
