 - `executable_path` is mandatory and must name the real Raspberry Pi binary.
 - The producer appends `tty:<tty_path>` automatically; do not put `tty:` in
   `radar.kamil_adc.args`.
+- The producer derives the sweep point count from the Kamil ADC TTY stream.
+  `radar.sweep.start_hz` and `stop_hz` define the synthetic frequency axis;
+  `radar.sweep.points` is not a Kamil ADC setting.
 - The laser-control driver is vendored under `python_app.hardware_full.laser_control`.
 - `laser_control` and `kamil_adc` are treated as one hardware configuration.
