wip(step2f): coherent field -- flakes, speckle, grid, roof fixed; 3 crumbs + 636 ms left; last edits UNCOMPILED

Stopped by low memory (another app at 14 GB; processes failed with 0xC0000142).
r6 (compiled and measured, owner playing during the run), step 2e -> step 2f r6:
  crumbs < 1 m^3 (max per profile)   2,898 -> 3        FAIL (0,0,0,0,2,1,3,2)
  flakes (shard share / p95 angle)   40.7% / 84.2 deg -> 2.1% / 33.1 deg   pass
  lattice-scale detail energy        0.832 -> 0.016    pass
  grid signature (autocorrelation)   0.666 -> 0.349    pass
  min solid share / roof openings    2.7%, 26,657 -> 79.2%, 0   pass
  worst profile ring time            642.8 -> 636.3 ms FAIL (6 workers, 259^3)
Step 2e measured 642.8 ms here vs 570 ms idle earlier: the game was costing ~12% during this run.
Brick proofs + audit, seams + injected seam, 1 vs 6 worker determinism pass. After r6, feature
probabilities were lowered to remove the last crumbs: NOT compiled, NOT measured. TraversalSeeds,
in-game captures and the LOD-rejection figure for 2e are still to do. Reject screenshots included.
