Overview

Runtime, per-job-class parking/blackhole mechanism for Sidekiq incident response.

Two modes per job class (see lib/sidekiq/CONTEXT.md and docs/routing-how-it-works.md):

- park (default, reversible): divert jobs to a worker-less parking queue.
- blackhole: drop jobs entirely (only for classes safe to lose).

State lives in a single Redis hash; the hot path reads a whole-hash snapshot refreshed at most once per cache_ttl_seconds, so per-job cost is an in-memory lookup rather than a Redis round-trip.
