check / check (push) Waiting to run
The receiver, resubmit and replay handlers now parse the request and make one call. Engine.StoreEvent stores an event with a pending delivery for each active target and the totals in one transaction, then queues them; Engine.CreateReplay does the same for one replay delivery. The handlers take *delivery.Engine, so the Notifier interface and its bridge are gone. Archives and CircuitBreakers stay because the handler tests fake them. The tests that read a queued task moved to the engine's tests; the handler tests use an engine that is never started. Model: opus-5-5
