nx_world_grade.nx

nx_world_grade.nx -- GRADE A LIVE nx_wasm_craft WORLD WITH nx_world_quality_grader. The gap this closes, measured 2026-09-01: nx_world_quality_grader.nx had shipped on 2026-05-16 and had NEVER BEEN BUILT, and even once built it takes a heightmap ARRAY in process and has no argv -- so it could not be pointed at any world that actually exists. The published /world/beach page had no referee at all. This organ is the missing arm: it runs the SAME engine source the page wasm is compiled from (nx_wasm_craft as a lib, which nx_world_snap already does natively) and hands the grader the real terrain. NO DUPLICATE RULER IS CREATED HERE. The terrain comes from the engine own mob_ground, the verdict comes from the shipped grader, and this file only composes the two and prints. usage: nx_world_grade <identity_v> <seed> [ticks] identity_v 2 + seed 20260728 IS the served beach: sites/nishifamily/world/beach.html carries const NXV=2 and ex.init_v(BigInt(NXV),BigInt(20260728)). exit: 0 graded | 2 usage SCOPE, DECLARED SO THE NUMBER CANNOT BE OVER-READ: the heightmap axes are measured from the live world; BIOME_COHERENCE and FEATURE_VARIETY are NOT supplied, so the grader abstains on them (score 0, verdict MARGINAL) and the grade therefore CANNOT reach S by construction. That ceiling is printed beside the grade rather than left for the reader to discover. license_tier: ORIGINAL No hw writes (Rule 26).
