  "summary": "Pure-reference catalog of cache-coherence patterns across the request path. Defines the five-tier cache stack (browser → CDN → reverse-proxy → application → data store), the per-tier cache-writing patterns (cache-aside, write-through, write-back, write-around, refresh-ahead), and the canonical invalidation strategies (TTL-only, event-driven purge, surrogate keys, version-tagged URLs, soft purge), plus an anti-pattern table and a worked multi-tenant coherence-test example. Deep detail - the RFC 9111 Cache-Control / Vary / ETag directive tables and the cross-tier coherence + per-tier test surface - lives in references/. Use for pattern selection, Cache-Control header design, and coherence audits; use a cache-key-collision check when the question is whether two requests in an existing system collide on a concrete key scheme. Consumed by redis-cache-tests, cdn-cache-purge-tests, varnish-test-vtc-syntax, browser-cache-control-tests, and the cache-key-collision check.",
