Map the exact transcode lifecycle before Phase 5.2 code changes begin.
No functional code changes.
Key findings documented:
- _activeTranscodingJobs: process-local, not persisted across pod restarts
- playSessionId: caller-supplied nullable string; three HA failure modes
- DeleteTranscodeFileTask: age-only cleanup, unsafe for shared NFS storage
- _activeLiveStreamSessions: process-local ConcurrentDictionary, cannot be
inherited by a takeover pod without durable store rehydration
- NFSv3 confirmed (nfsvers=3). Close-to-open consistency advisory; recovery
must skip the last incomplete segment and restart one segment earlier
- Minimum recovery state: 10 fields including server-generated sessionId,
ownerPod, manifestPath, lastCompletedSegmentIndex, lastHeartbeatUtc
Closes Phase 5 Issue 5.1.1
