Sep 5 06:29 Align the six p2 extension grids with the audited set: 10M-sample measured-D headers, kappa-audited ib16_p2 payload (supersedes the training-header upload) 05:25 Add six high-bpw p2 extension grids ib11_p2..ib16_p2 (5.5-8.0 bpw); supersede sphere-staging-20260904 Aug 30 15:02 Restructure: only 27 self-contained ib*_p*.sf grids (corrected 2026-08-29) Remove legacy *_nopti names, npz search artifacts, and the three nested sf-map folders (maps live in their own sf-map-* repos). Grid bytes are the corrected fp16-CLVQ/header-audit set; header distortion is raw fp16 MSE so kappa = 1 - D/p.
