hive-host-sock

Wire types for the host admin socket (/run/hyperhive/host.sock) — the host-control protocol spoken between the hivectl operator CLI and the hive-c0re daemon.

Why it's its own crate

Re-homed out of hive-sh4re so a standalone hivectl depends on just this protocol crate instead of the whole daemon-shared crate. hivectl drives the full hive (spawn / kill / destroy / rebuild / deploy) over this socket without linking hive-c0re; keeping the request/response shapes here is what makes that thin dependency possible.

Shape

Serde-derived request/response enums for the host admin protocol. The larger shared payload types some variants reference (Approval, AgentStatusRow) stay in hive-sh4re — this crate is only the protocol envelope, no server or client implementation.

Its own jobs module is the exception: the job-queue vocabulary hivectl needs (Source, State, PermPayload, NodeId) is protocol-local. The typed DagView/NodeView projection that used to live there is gone — the queue is served as a generic graph (hive-jobq-wire), not as a second hand-written view.

See docs/boundary.md (host admin socket access) for the trust model around who may connect to the socket, and hive-priv-sock for the sibling split on the privileged-helper socket.
