- _decode_serial_number: read from data[11:] not data[:8] — was returning
the LENGTH_ECHO byte (0x0A = '\n') instead of the serial string
- _extract_peak_floats: search for channel label strings ("Tran" etc) and
read float at label+6; old step-4 aligned scan was reading trigger levels
instead of PPV values
- get_events: add debug=False param; stashes raw 210-byte record on
Event._raw_record when True for field-layout inspection
- server /device/events: add ?debug=true query param; includes
raw_record_hex + raw_record_len in response when set
- models: add Event._raw_record optional bytes field
