Smart Router

For each planned step, the Smart Router queries the discovery layer for candidates that advertise the required capability, then scores each one on:

- 25% relevance (capability match weight, learned per mission_type), - 20% historical success rate, - 15% verification pass rate, - 10% freshness (recency of the last successful call), - 10% latency score (lower p95 wins), - 10% policy fit (1 − provider risk, scaled by certification), - 5% receipt trust (vendor signs receipts → boost), - −5% normalized cost (cheaper relative to peers wins a small premium).

The winner's score reasons are surfaced to the audit log and the UI: the route explanation enumerates "Acme Search chosen — certified provider; verification pass rate 94%; fast (p95 1200ms). Alternatives considered: Cheap Search (score 0.65, $0.04)."

• Mission Engine— The orchestration layer that walks a Mission through plan → quote → policy → execute → verify → complete with durable state transitions.
• Provider Quality Score— A computed [0,1] score per provider, derived from real execution data over a 30-day rolling window.
