Ofer Shaal 003d21b30e docs(bet4): pre-register LB-B&B IVF vs plain-IVF nprobe gate (FROZEN) ... Closes the BET 4 caveat left open by ADR-201: the region-pruning IVF kernel was only run against ACORN (BET 2), never against its natural incumbent, plain IVF nprobe, on unfiltered ANN. Frozen gate: WIN = >=2x member-scan reduction at matched recall@10 (R=0.95) AND wall-clock win across nclusters in {64,256,1024}; KILL = <1.5x or wall-clock reverses. Two controls: exact-vs-exact pruning-fraction probe + low-d (PCA-8) soundness control. Honest prior: NO-GO lean (128-d concentration makes the triangle-inequality bound loose) — the IVF-level companion to ADR-199. Branch off clean main; B&B kernel rebuilt self-contained (BET 2's lives only on #536).		2026-06-05 00:25:29 -04:00
