CALL NUMBER: resilience_and_reliability_engineering_patterns.circuit_breaker DEFINITION: pattern preventing cascading failures by stopping calls to failing service; trips open on threshold violations

Invoke this skill to understand circuit_breaker down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from resilience_and_reliability_engineering_patterns

• cascading_failure (d1): failure propagation from one component to others; circuit breakers and bulkheads prevent this

CONSUMERS (what needs this)

circuit_breaker_half_open_limit, circuit_breaker_state_closed, circuit_breaker_state_half_open, circuit_breaker_state_open

Projected from the resilience and reliability engineering patterns KB (118 concepts / 34 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.

(leaf — this is an actual skill.)
