- `h8536_emulator_rx_probe.py "04 00 00 80 00"`: append the checksum, inject the host frame through SCI1 RX, and summarize responses.
- `h8536_emulator_rx_probe.py --uart-timing --uart-baud 38400 "04 00 00 80 00"`: inject all six host bytes with 8N1 wire spacing of about 260 us per byte, letting RXI/TXI/timers interleave; if the ROM has not cleared `RDRF` before the next byte, the SCI model raises `ORER`.
- `h8536_emulator_rx_probe.py --preset connect-lcd`: replay the current CONNECT LCD activation candidates.
- `h8536_emulator_rx_divergence.py --default-frames --uart-timing --wait-heartbeats 2 --summary-only`: run the focused RX divergence trace for the bench mismatch. It flags whether a frame reached cmd0 `BC69`, cmd1 `BCD7`, retry echo, command-7 replay, autonomous `BAF2` report output, or the TX/RX overlap-collapse path.
- `scripts\serial_table_dump.py --port COM5 --relay-port COM6 --start 0x000 --count 0x200 --log captures\table-read.txt`: read-only command-1 sweep of the firmware-exposed serial table state for EEPROM/shadow inference.
