Function clear_event 

async fn clear_event(services: &Services, event_id: &EventId) -> ClearSummary

Drops every stored verdict gating one event’s re-evaluation.

The cached policy decision, the retry backoff, and the soft-fail marker each hold the next delivery back, so recovery has to clear all three. Dropping the backoff is what opens the gate, and it follows the policy decision, so an interrupted run never re-evaluates against a stale verdict.
