Editor-only brick API (<= 8^3 points per call, TunnelNetwork/Underwater op-stack routes, 1.16% scalar fallback). Exact: 0 Q16/sign disagreements on the full 259^3 ring and the five-seed probe set, same hash on 1 and 6 workers, reach shrink still caught (18,107 Q16 / 735 sign). Speed: 69.19 s wall, 17.6 us/sample vs live 7.04 s, 1.65 us/sample. Stack sampler (inclusive): BuildChunkCache 93.5%, PropagateSdfOverBox 92.5%, BuildActiveOpList 92.6% -- each brick rebuilds the cache windows and active-op lists; EvalBlock itself is 3.6%. Live path attribution (inclusive, 68,934 stacks): op-stack RoomGraph EvalBlock 54.4%, SDF and spatial candidate scans ~28%, tunnel core 18.4%, passage floor segment 15.0%, structural posts 14.6%, noise octaves 2.6%, disturbances 0.6%, diff layer 0.3%.
