  "title": "KatoANN: Enabling Near-Exact Vector Search at the Speed of Lossy Scans with CPU Matrix Engines",
  "summary": "The method replaces memory-bound lossy distance scans (or a full-vector refinement pass) in partition-family ANN search with a batched rank-then-refine scan over a single 16-bit SQ16 code, using Intel AMX to reuse fetched codes across queries. Costs include 16-bit storage per vector plus the rank-refine scan logic, and it depends on Intel AMX CPU hardware and on batch query availability to shift the workload from memory-bound to compute-bound. It can fail under low query concurrency, where batching yields little reuse, on hardware without AMX, or on workloads where SQ16 high-byte ranking misidentifies survivors and recall degrades.",
  "rationale": "The technique is relevant to retrieval-heavy RAG pipelines but requires specific Intel AMX CPUs and batched query traffic that the reader's 24 GB GPU setup does not provide, so it warrants monitoring rather than adoption or testing now.",
