Approval Queue
A human-in-loop checkpoint that fires when policy returns requires_approval. Mission halts in awaiting_approval until granted or denied.
The Policy Engine has three possible decisions: allow, deny, requires_approval. The third path triggers the Approval Queue: an Approval row is written, the mission moves to awaiting_approval, and execution halts.
Approval rules are configurable per policy: typical ones are "human review if mission_cost_gt $10", "human review if vendor_risk_gt 0.6", "human review if data_sensitivity_gte confidential". An admin grants or denies via POST /v1/missions/{id}/approvals/{id}; granted approvals let the mission resume, denied ones terminate it.
