+**1. Book Shows "Available" After Deletion Until Library Scan**
+- **Issue:** Deleted books remained "available" until the next library scan
+- **Cause:** plex_library deletion used title/author matching, but availability check used ASIN matching
+- **Impact:** Title variations (e.g., "Book Title" vs "Book Title (Unabridged)") caused plex_library records to persist
+- **Fix:** Changed plex_library deletion to use ASIN-based matching (same as availability check)
+- **Result:** Books immediately show as NOT available after deletion, can be re-requested right away
