nx_indoorgen_lib.nx -- GR6 INDOOR ROOMS BY CONSTRAINT SOLVE (the Infinigen 2.0 expansion, /compare/graphics watch contract ig_room_solve, operator 2026-08-17 "properly emitting in the infinigen way"). COMPOSES the incumbent solver (nx_part_solver_lib, the Infinigen-Indoors transfer) -- one solver in the estate; this file only DECLARES rooms and consumes solutions. Shape: an ARCHETYPE (cottage / hut / stonecot) is data rows here; ig_room_solve(arch,variant,salt) builds a declarative constraint set in memory (envelope + pairwise noclip + door clearance + wall-hug bands + mate face rows), runs ps_solve, then QUANTIZES the solved placements to voxel cells and enforces the pre-declared ACCEPT RULE: solved AND quantized-disjoint AND door-approach-free AND all-inside. A set that cannot satisfy is REFUSED (return 0, nothing emitted) -- never overlapped furniture. Variants differ by hashed initial placements (different local optima of the SAME constraints -- the Infinigen pattern: one program, seeded variation). The world engine consumes only the emitted DATA TABLE (nx_indoorgen_data.nx, written by the nx_indoorgen CLI): the wasm worlds never run the solver, so the solver's mmap arena never meets the wasm memory bound. license_tier: ORIGINAL
