Protocols

The Hex ↔ Main protocol describes the intended shared I²C transport, chain enumeration, semantic commands, and the questions that must be answered before firmware can interoperate.

There is no finalized wire protocol. The examples establish vocabulary and responsibilities; they do not allocate opcodes, byte offsets, or compatibility guarantees.

Future formal message contracts belong alongside this page. The separate game API and WebSocket interface is described at the software architecture level until its hosting and application design are defined.
