Package cluster composes a machine's local runtime with remote runtimes for its peers (spec 022).

Package fake is an in-memory runtime.Runtime for fast, deterministic unit tests (backlog AO-014: "Interface is mockable — a FakeRuntime powers fast unit tests").

Package gateway is an optional runtime.Runtime decorator (backlog AO-042) that puts spend caps, tracing, and failover in front of any underlying runtime — the role agentgateway/plano play in front of providers.

Package meshjoin hosts the spec-024 enrollment endpoints on the hub daemon:

Package native is Fort's NativeRuntime (backlog AO-014): it spawns agent CLIs itself — no Multica — normalizes their stdout into runtime.RunEvents, injects stdin for Signal (human-in-the-loop), and tracks exit codes.

Package node exposes a Fort's local runtime over HTTP so another Fort — the control plane — can dispatch runs to this machine (spec 022).

Package relay maintains fort serve's outbound tunnel to the 028 gateway: one WebSocket to the broker, per-client-session Noise IK handshakes (exec/relay/secure), and sealed HTTP/SSE service against an injected http.Handler — the transport never imports ui (seam: it moves bytes).

Package remote dispatches runs to another Fort over HTTP (spec 022).
