Crate wist_api 

Cross-process agent-seam messages for the wist control plane (gateway ↔ agentd).

A seam is a runtime coupling point between two independently deployed processes ({route, request body, response body, owner, compat, api_version}). This crate owns the wire messages of the agent-facing seams so gateway and agentd use a single definition instead of keeping a copy each. (The center-facing seams — gateway/register, gateway/status, … — are generated into wist-control, not owned here.)

Each module is one seam topic and maps to a route: enrollment (agent/enroll, agent/credentials:renew), status (agent/status), uplink (agent/uplink:poll), work (agent/work:*), action_plan (agent/action-plan), action_result (agent/action-results), facts (agent/facts), discovery_policies (agent/discovery-policies:poll).

Seam messages reference domain types that are shared by more than one seam (HostProfile, CredentialBundle, AgentIdentity, …). Those live in wist-contracts — the common base of every participant — and are re-exported here so callers can pull a whole seam from one place. wist-contracts keeps data-plane / internal objects only.
