## Critical Blockers Fixed - Remove playbackState.addError() which broke audio_service permanently - Move error handling from audio_handler to song_list where UI context exists - Display error in SnackBar instead of destroying playback stream - Add escapeChar parameter to LIKE queries for correct wildcard handling - Fixes broken search for titles with _ or % characters - Add dismissScanError() method to allow closing error banner - Previously banner couldn't be dismissed (missing notifyListeners()) ## Improvements - Remove dead livePaths list, use companions.isNotEmpty instead - Add initial progress update to show total files when scan starts - Add tooltip to now_playing_screen Zurück button - Add proper error handling in song_list with async/await ## Testing - Add regression test for CRITICAL-1: empty scan doesn't delete songs - Add regression test for CRITICAL-2: tombstoned files restore on re-scan - All 11 tests pass Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
