The native service and the Flutter player each ran their own 5%-to- target fade-in, and both could drive audible volume at the handoff, producing a jump or ramp reset. The Dart ramp now starts exactly once from the handoff-confirmation path: the player still pre-starts at 5%, and _confirmarAudioFlutterListo() starts the ramp in a finally block so it runs whether the native confirmation succeeds or fails — the alarm can never stay stuck at 5% if the native side is already gone. Work unit 3/3 of alarm-volume-ramp-restore (fade-in dedup).
