nx_worldgen_refine.nx -- TEAM-OWNED worldgen quality gate + AUTO-REFINE loop (operator 2026-06-10: "s class exceed instead of our crummy proc gen -- build the team to do the work"; operator 2026-05-16: "build an iterative loop ... i dont want to have to manually check if you generate good maps"). The loop nobody has to babysit: nx_procgen_landscape(seed, preset, w, h, density) -- current generator -> nx_world_quality_grade (8 axes, Q14, sealed F..S, refine_axis) -> hill-climb the exposed knobs (preset x density x seed batch) -> bank the BEST params to /tmp/nishi_worldgen_best.conf (data-driven; the voxel build reads params, never hardcodes them -- Cardinal 11) HONEST BASELINE FIRST: the first sweep grades the CURRENT generator as-is. "Crummy" becomes a NUMBER with named failing axes; every later rung (composed primitives: causal rivers, erosion, constraint placement per the procgen cardinals) must MOVE that number through this same gate. Note the grader's own posture: Minecraft/No-Man's-Sky/Houdini have NO mathematical world-quality verdict -- this instrument is itself the EXCEED axis; S-class = the generator earns NX_GRADE_S under it. WORLDGEN lines -> stdout + /tmp/nishi_worldgen_gate.log. Exit: 0 if best grade >= floor (argv[1], default C=2), else 1. license_tier: ORIGINAL
