Struct memVectorStore

core/services/routing/router/embedding_cache_test.go:58–62

memVectorStore is an in-memory KNN store with exact-vector hits, used to exercise the cache layer without a real local-store backend. Similarity is 1.0 for an exact match (after vector quantisation), 0.5 for "close" (configured via the second-arg suffix), 0.0 otherwise.
