about

nx_indoor_gate.nx -- ★R8: INDOOR scenes (room + constraint-solved furniture layout). T1 a furnished room builds + renders (shell + furniture; interior renders, walls/floor fill the frame) T2 ★CONSTRAINT VALIDITY: the placed furniture has ZERO overlapping pairs (collision-free layout) + in-bounds T3 SEED VARIETY: different seeds -> different valid layouts (layout signature differs, both collision-free) T4 determinism + interior render knowledge/nx_indoor.png (3 furnished rooms) license_tier: ORIGINAL expect_exit: 0
