Memory retrieval stops reading only whole-sentence vectors: reusing a frozen encoder's token states lifts Qwen3-4B average Recall@10 from 62.5 to 75.7
Memory retrieval no longer compares only whole-memory vectors: sparse matching over token states a frozen encoder already computes, fused with whole-memory similarity, raises average Recall@10 on Qwen3-Embedding-4B from 62.5 to 75.7 without additional training.
