-## UART log replay
-
-Use the `UART Replay` button (or `Dosya > UART Log Replay...`) to feed a recorded
-UART `.log`/`.txt` file back through the same parser used by the live serial port.
-Choose the raw GPS update interval (default `200 ms`) and sensor/fused update
-interval (default `50 ms`) in the replay dialog. Press `Replay Durdur` to stop.
-
-Recorder timestamps are optional and do not control replay speed. The replayer
-removes a leading timestamp when present, identifies `source=gps` as raw GPS and
-`source=imu_corrected` or `[FUSION]` as fused/sensor output, then synthesizes the
-two update timelines while retaining the original UART line order. Other UART
-diagnostic lines are forwarded with the surrounding location update.
