On definitive failure of the picture or audio slip, the saga now reaches a
Failed state and recovers end-to-end:
- Picture/audio track slips carry TrackId + ProcessKind variables and a
subscription to a fault translator (TrackProcessingSlipFaultConsumer) that
turns RoutingSlipFaulted into a typed Track{Picture,Audio}ProcessingFailed
- The saga stores the final object keys from the start event and, on failure,
transitions to Failed and publishes TrackProcessingFailed
- TrackProcessingFailedConsumer runs a cleanup slip that removes the orphaned
final picture/audio copies and marks the track LifeCycleStatus=Failed
(MarkTrackAsFailedActivity) — the track stays as a visible, recoverable record
- Migration for the new saga columns
Verified: Worker boots against RabbitMQ + Postgres in Docker; the new
endpoints (fault translator, failed consumer, mark-track-as-failed) configure
and the bus starts clean.
Build: 0 warnings, 0 errors.
