  "title": "Beyond the Final Embedding: Retrieving Memories from Token-Level Evidence",
  "summary": "The method replaces single-vector query-memory similarity with sparse token-level matching over the contextual token representations already produced by the embedding model, aggregated and combined with whole-memory similarity, optionally refined by a low-rank query adapter trained while the encoder and stored representations stay fixed. The training-free variant costs only token-level index storage and per-query matching latency, but storing token representations for all memories is substantially larger than one vector per memory, and the adapter variant adds a supervised training step with labeled data. It can fail when query-token matches fire on irrelevant memories (raising false positives), when token index size or scoring latency exceeds the memory retrieval budget, and when gains on the eight reported benchmarks do not transfer to the reader's memory distribution.",
  "rationale": "The training-free variant is cheap to prototype on constrained infrastructure since it reuses existing embedding-model outputs, but the storage and latency overhead of token-level indexes plus the need to validate retrieval gains on the reader's own memory workload make workload-specific testing necessary before adoption.",
