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. fixes #269 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
