Summary
Adds ADR-0049 documenting the decision to add semantic (similarity-based) response caching, layered on top of the existing exact-match cache (ADR-0033) and backed by
RagProviderInterface(ADR-0045).Key decisions recorded
SemanticCacheis a standalone component, not aCacheInterfaceimplementation (different lookup model: text similarity vs. string-key equality).ChatResponse/value-object serialization (toArray()/fromArray()) as a prerequisite, since responses are stored in vector-store metadata.Tracking
Implementation tracked under milestone
v0.7.3 - Semantic Cachingin WebFiori/ai: issues #143–#149.Notes
