-### Two Emby Profiles — Why Both Exist

-**emby-fallback** (every 30 minutes, Emby stays running):
-- Syncs: users.db, library.db, authentication.db, config/
-- Skips: \*.wal, \*.shm, transcodes/, logs/, cache/
-- Why: WAL files are written while Emby runs — copying them would produce a corrupt database on HOST2
-- Result: HOST2 is always within 30 minutes of HOST1 on watch state and user activity
+### The `emby` Profile and Watch-State Sync
 
 **emby** (Sunday 2:30am, both Emby instances stopped):
 - Syncs: everything except transcodes, logs, cache, crash files

 - Why: WAL is checkpointed on clean shutdown — safe to copy everything
 - Result: HOST2 gets a gold-standard Emby state once per week
 
-The two profiles work together. emby-fallback keeps HOST2 current for immediate fallback.
-emby gives HOST2 full fidelity once per week. Neither alone is sufficient.
+Between weekly mirrors, Emby **watch/resume state** is kept current by
+`Media/play_state_sync.sh`, which reads and writes play state over the Emby API every
+30 minutes (CRITICAL_MAINTENANCE_SCRIPTS) — so HOST2 never falls more than one cycle
+behind on what's been watched. This replaced the old `emby-fallback` dirty-rsync profile:
+copying Emby's live SQLite databases mid-write risked landing a half-written WAL file on
+HOST2, and an API-level sync sidesteps the database-consistency problem entirely.
