Locks the wire format between /opt/cni/bin/flock and flock-agent. ADD returns a CNI Result, DEL returns success/error, CHECK returns success/error. Connection-per-RPC, newline-delimited JSON. - pkg/cni/rpc.go: shared Op + Request + Response + framed encode/decode. - pkg/cni/rpc_client.go: net.Dial + EncodeRequest + DecodeResponse; rpcSocket overridable for tests. - pkg/cni/plugin.go: real implementations of CmdAdd/Del/Check that call through, mapping agent errors to types.Error. - pkg/agent/rpc.go: rpcServer with swappable AddHandler/DelHandler/ CheckHandler (defaults: not-implemented for ADD; idempotent-no-op for DEL/CHECK so kubelet teardown of a never-ADDed pod doesn't fail). - pkg/agent/server.go: replaces the M1 accept-and-close placeholder with rpcServer.serve(ctx, listener); listener closes on ctx cancel. Tests cover: Request/Response JSON roundtrip, end-to-end client → unix-socket → fake server, agent error → CNI types.Error mapping. ADD remains "not implemented" until netlink + IPAM wire-up — the agent returns an error and kubelet will fail pod sandbox creation IF a node were configured to use this CNI. host001's CNI plane is still 100% Calico, so this changes nothing observable on the cluster.
