Overview

Handles inflow: new jobs at enqueue time (perform_async/perform_in, push_bulk). Blackhole aborts the push; park rewrites the queue so the job lands in the worker-less parking queue.

No per-job log or metric here — during a flood that would emit millions of lines. Observability is the Web tab’s live aggregates + operator-action logs only (see docs/routing-how-it-works.md).
