S3's far cap sat up to 8.2 m above the near roof and read as floating pieces. The far render cap now projects onto the owning strate's upper boundary (density unchanged), on a global XY lattice, LOD4 16-voxel grid + LOD5-8 128-voxel. Cap agreement 0.05 cm (100 cm control detected), 2520/2520 upward rays hit roof on the owner walk. Far recipe v2; LOD0-3 hashes equal S2/S3. Tile p95 flat; cold clipmap +4.4%. Far-cliff fluting left open (coarse MC step). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01MmSoF64BbRFmk9C3p1VsBJ
