CALL NUMBER: resilience_and_reliability_engineering_patterns.cache_invalidation DEFINITION: removing stale cached entries; must be timely to prevent serving incorrect data

Invoke this skill to understand cache_invalidation 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

• cache_stampede (d1): concurrent cache misses causing thundering herd on backend; mitigated by probabilistic early expiration

CONSUMERS (what needs this)

cache_aside

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.)
