Module protocol 

The client<->daemon wire protocol (version 7).

Typed request/response enums plus bus events. Framing lives in wire; a serialized shape change bumps PROTOCOL_VERSION. Version 4 bumped on an addition. Version 5 bumped on a new AppConfig field: that struct is deny_unknown_fields, so the additive rule below does not cover it and an older daemon cannot decode depends_on. Version 6 bumped on a retype: Response::Reloading became a struct variant to carry the apps a staged reload refused, so it serializes as an object where an older peer reads an array. Version 7 bumped on the same retype applied to Response::Restarted, which a staged restart refuses apps of for the same reason and had nowhere to name them.

A *_wire_v7 test pins today’s shape. A v1_*_fixture_still_deserializes test pins an old peer’s payload and never renames.

Modules

channelDeprecated

The shepherd channel’s wire types. Moved to the shep-channel crate; this path is kept so consumers of 0.1.x do not break. Use shep_core::protocol directly instead.

events

Bus events broadcast to subscribed clients

frame

Anything the daemon writes to a connected client

request

RPC frames: requests, responses, envelopes, and structured errors

wire

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

Enums

ChildMessage

Child -> daemon shepherd-channel message (spec §7, kebab-case kinds)

ShepherdMessage

Daemon -> child message

Constants

CHANNEL_VERSION

The value the shepherd exports as SHEP_CHANNEL_VERSION to every child it opens a channel for.

MIN_SUPPORTED

The oldest protocol this build accepts from a peer.

PROTOCOL_VERSION

Wire protocol version.
