- datalog_session.dart: DatalogSession model with toMap/fromMap, duration helpers - datalog_db.dart: SQLite schema (sessions + frames tables), batch insertFrames, getSessions, getFrames, deleteSession, closeSession - datalog_recorder.dart: listens to raw frame stream, buffers PendingFrames, flushes to DB every 500ms via Timer, finalises session on stop() - datalog_player.dart: loads StoredFrames from DB, replays at original timing adjusted by speed multiplier (0.25x–8x), play/pause/stop/seek, onProgress cb - datalog_provider.dart: datalogDbProvider, datalogRecorderProvider, datalogPlayerProvider singletons; RecordingNotifier (idle/recording state); sessionListProvider FutureProvider; PlaybackNotifier with full playback state - pubspec.yaml: added path ^1.9.0 dependency
