Omar SobhandClaude Fable 5.1	44caeb8110	embedded3 PERF-3 P1-3 (f): the mask build's whole-grid scans as parallel per-entry maps (cell classification with the anchor as the smallest fluid index, the three face-kind tables, the merging scan's small flags, the centroid-shift table per face) — slab flag ny 62 CSV byte-identical, device moving/cg green; ny 124 rebuild block 2,680 → 2,569 ms per step (build_mask 409 → 309) ...

Omar SobhandClaude Fable 5.1	5a376630a7	embedded3 PERF-3 P1-3 (c)(d)(e): the moving path's host mirror persists between steps and only the arrays the rebuild reads come down (u, v, w, p, the previous velocities) and only those it writes go up (u, v, w, p — the correction stays on the device; the first form re-uploaded a stale one and the byte gate caught it); the operator assembly in parallel by plane with the predicates lifted off the solver; the fine export's casts as parallel maps — slab flag ny 62 CSV byte-identical, device moving/cg green; ny 124 rebuild block 3,386 → 2,680 ms per step ...
