Durable Orchestration Control Plane

Rules and deliveries are separate durable facts

workflow_event_subscriptions stores the declared relationship between a typed source event and a target workflow. workflow_event_deliveries stores each concrete activation attempt. Keeping policy separate from its effects makes the system explainable: an operator can see whether a rule did not match, a delivery is waiting, a worker holds a lease, a retry is scheduled, or a target run was actually requested.

Capability is a pre-dispatch contract

Every adapter projects a versioned RuntimeCapabilityManifest. The runtime evaluates namespaced capabilities and configuration-sensitive requirements — including allOf/anyOf alternatives — before dispatch. An agent therefore receives a typed, actionable capability mismatch instead of repeatedly attempting an operation its runtime cannot perform.
