Register map(s) for this device, with a note of how far each has been checked. Addresses are 0-based, as on the wire. Scale and byte order are confirmed only at the hardware-verified rung.
Round-trips through a real Modbus stack with no overlapping addresses and a word-order-sensitive codec — the map is internally coherent and wire-decodable. Does NOT prove byte-order or scaling match a real device: the emulator is seeded from the map's own types, so a uniformly wrong byte-order still round-trips. Only hardware-verified confirms byte-order/scale on the wire.

⚠ The device provides no facility to revert the baud rate remotely. Once written, the device will lose communication until the client baud rate matches the new configuration. — Starkest reads only; we never write a control register.

Each rung states what it proved and what it did not. Gray until proven; green is earned by hardware only.
