- Immersion tracking: `src/core/services/immersion-tracker/`
Includes stats storage/query schema such as `imm_videos`, `imm_media_art`, and `imm_youtube_videos` for per-video and YouTube-specific library metadata.
Library-entry identity aliases and merge recommendations are persisted alongside this schema; the stats HTTP and SPA layers only expose and present those domain decisions.
`delete-maintenance-scheduler.ts` coalesces and serializes stats deletes; expensive deletion and summary rebuilds run in `delete-maintenance-worker-thread.ts` while the tracker queues playback writes. Each batch uses one transaction, lexical update, rollup refresh, and lifetime rebuild.
`delete-maintenance-scheduler.ts` coalesces and serializes stats deletes; the expensive work runs in `delete-maintenance-worker-thread.ts` while the tracker queues playback writes. Each batch uses one transaction, lexical update, rollup refresh, and incremental lifetime subtraction (`planLifetimeRemovals`/`applyLifetimeRemovals` in `lifetime.ts`). Merges, moves, AniList reassignments, and `stats cleanup -l` use `repairLifetimeSummariesFromMedia` (recompute from the per-video media ledger). The full lifetime rebuild survives only as the empty-table bootstrap; anywhere else it would collapse lifetime totals to the session retention window.
