Module codec 

Length-prefixed frame codec for reading and writing protocol messages.

Wire format: [len: u32 BE][id: u32 BE][flags: u8][CBOR(v, t, p)]

The correlation ID and flags sit in a fixed-position binary header so that relay intermediaries can route frames without CBOR parsing.

Constants

MAX_FRAME_SIZE

Maximum allowed frame size (4 MiB).
