nx_explode3d_gate.nx

nx_explode3d_gate.nx -- teeth for R2: the 3D exploded-view engine DRIVEN BY THE REAL STEP ASSEMBLY. Parses banked as1-oc-214.stp (nx_step_parse R1a) -> DFS the occurrence tree -> one 3D part per leaf instance (box/prism STAND-INS by product name; real face tessellation = R1b) -> nx_explode3d staged radial explode -> nx_meshrender frames -> ANIMATED APNG knowledge/nx_explode_as1.apng (assemble<->explode loop = the explodeview signature). T1 part count == INDEPENDENT occurrence-expansion count (two different computations agree) · T2 mean pairwise part distance strictly MONOTONIC in t · T3 exploded >= 2x assembled spread · T4 pose determinism (same t -> same bytes) · T5 staged depth (depth-3 parts travel further than depth-1) · T6 renders non-vacuous + assembled differs from exploded · T7 APNG written (signature + size). expect_exit: 0 license_tier: ORIGINAL
