Module wire 

Frame encoding shared by daemon and client Frame encoding: u32 length prefix + JSON payload

One codec constructor + encode/decode helpers shared by daemon and client so framing parameters can never drift between the two.

Enums

WireError

Error type returned from encode_frame and decode_frame

Constants

MAX_FRAME_BYTES

Hard ceiling per frame; larger is a protocol violation

Functions

codec

Builds the shared length-delimited codec (u32 BE prefix, 16 MiB cap)

decode_frame

Deserializes one frame payload

encode_frame

Serializes one value to a frame payload

reply_id

If frame is a reply, the id it answers; None for anything else, including an event and a frame that is not JSON at all.
