Module agent 

Agent lifecycle: everything between a configuration and a running robot — sockets, candidate discovery, certificate, QUIC endpoint, the session Engine, signaling, and the maintenance that keeps all of it alive (port-mapping lease renewal, certificate rotation, network-change re-gather).

seydd and seyd-ffi are both hosts of this type. A host supplies media (push_video, push_message), consumes AgentEvent, and owns nothing of the lifecycle itself — which is what keeps the daemon and the SDK from drifting apart. Anything a host does differently (where frames come from, where commands go, how the publisher is told to reconfigure) stays in the host; anything that must be identical everywhere lives here.

Structs

Agent

A running robot agent. Cheap to clone; every clone refers to the same agent.

AgentConfig

How a robot is configured, independent of where that configuration came from — seydd.toml, a C seyd_config, or a test.

Enums

AgentEvent

What a running agent tells its host. The engine’s own events pass through unchanged; the rest describe the lifecycle the host no longer runs itself.
