nx_boneheat_gate.nx

nx_boneheat_gate.nx -- THE REFEREE FOR THE SOVEREIGN AUTO-WEIGHTS: a geodesic solve must BLEND at a joint, must NOT bleed across air, must announce an unsealed mesh instead of refusing it, must refuse a mesh with no skeleton BY NAME, and must be byte-deterministic -- while the nearest-joint control (modding MD4's own accept-rule control) is shown to do exactly what the geodesic solve exists to stop. Fixtures are BUILT AT RUN TIME under /tmp/nx_boneheat_gate (a detector that scans source must never meet its own fixture) and are AXIS-ALIGNED SQUARE PRISMS on purpose: their four walls and two caps lie on coordinate planes, so the voxeliser seals them without depending on the tilted-face dilation (that dilation stays in the lib for real meshes; the fixture must isolate the WEIGHT solve, not the seam heuristic). A closed prism with a three-joint chain; the same prism open at both ends; two prisms separated by 12 mm of air where one shell's joint is Euclidean-nearer to the other shell's vertices than that shell's own joint. Every solve is IN-PROCESS through nx_boneheat_lib, so a mutant of the lib is reached. license_tier: ORIGINAL expect_exit: 0
