Artist, ExternalId, OriginalPictureName and OriginalAudioName were
non-nullable with '' sentinels, which forced the unique (Source,
ExternalId) index to rely on a filtered "<> ''" clause. Make them
truly nullable and drop the empty-string sentinels, backfilling
existing rows to NULL. Also fixes a formatting regression
(`track != null&&`) introduced alongside the nullability change.
Register AuditableEntityInterceptor as a singleton and attach it through the
AddDbContext options callback instead of newing it up inside
Database.OnConfiguring. The interceptor is stateless, so a single shared
instance is reused across contexts and its wiring lives in the DI layer.
The design-time factory keeps working (interceptor is runtime-only, irrelevant
for migrations).
Verified: build + ef migrations list (design-time context) OK; the Worker host
builds and validates the full DI graph (reaches endpoint configuration) with no
captive-dependency or interceptor error.
Build: 0 warnings, 0 errors.

Adds the PlayList picture-processing lifecycle saga (correlated by PlayListId)
mirroring the track one, and generalizes the failure plumbing:
- Rename the track fault translator to ProcessingSlipFaultConsumer and use a
generic Workflow.SubjectId variable + ProcessKind; it now emits typed
Track{Picture,Audio}/PlayListPicture ProcessingFailed events for all slips
- PlayListProcessingStateMachine (+ EF-persisted PlayListProcessingState,
migration): starts on CreatePlayListResourcesEvent, finalizes on
PlayListPictureProcessed, and on failure marks the playlist Failed and
removes the orphaned final picture (PlayListProcessingFailedConsumer +
MarkPlayListAsFailedActivity)
- UpdatePlayListPictureActivity publishes PlayListPictureProcessed on success
- Picture slip carries SubjectId + PlayListPicture kind + fault subscription
Verified end-to-end in Docker (RabbitMQ + migrated Postgres): both saga
endpoints, the fault translator and cleanup consumers configure, and an
addressing cross-check confirms all 21 activity execute queues the builders
address exist (caught + fixed a kebab mismatch on mark-play-list-as-failed).
Build: 0 warnings, 0 errors.

Introduce a MassTransit saga state machine that correlates by TrackId and
tracks the two parallel processing slips (picture + audio):
- TrackProcessingStateMachine + EF-persisted TrackProcessingState
(pessimistic concurrency, EntityFrameworkRepository), migration added
- Starts on CreateTrackResourcesEvent; UpdateTrack{Picture,Audio}Activity now
publish TrackPictureProcessed / TrackAudioProcessed on success; when both
arrive the saga finalizes (Ready). Failure transitions to a Failed state
(cleanup wired in the next phase)
- Add LifeCycleStatus.Failed and the four outcome events
Verified: booted the Worker against RabbitMQ + migrated Postgres in Docker;
the saga endpoint 'track-processing-state' is configured and the bus starts
clean.
Build: 0 warnings, 0 errors.

- Move all .NET (6 projects, solution, Directory.*.props, nuget.config)
into backend/ so the monorepo root can host non-.NET projects later
- Remove throwaway test artifacts: player.html, pl.json
- Trim dead Flutter rules from .gitignore
Build from backend/Musify.slnx: 0 warnings, 0 errors.
