nx_worldpipe.nx -- ★R5 STAGED PROCGEN (the banked Minecraft-pipeline curriculum, engine-convergence rung 5): worldgen as an ORDERED STAGED PIPELINE over a MULTI-PARAMETER space -- not one noise call. STAGE 1 PARAMS six independent noise fields at (x,z): temperature / humidity / CONTINENTALNESS / erosion / weirdness / river. (Their 6th, depth, is the 3D-density param -- ours is a heightfield: named residual.) STAGE 2 SPLINE height BASE = piecewise-linear SPLINE over continentalness (deep ocean -> coast -> inland -> highland), the curriculum's core lesson: params map to height THROUGH SPLINES. STAGE 3 RELIEF ridged mountains scaled by WEIRDNESS and flattened by EROSION (high erosion = plains). STAGE 4 CARVER rivers CUT the terrain where the river field crosses its band (geometry change, toggleable). STAGE 5 BIOME classified from the parameter VECTOR (temp x humidity x cont x weirdness) -- NOT from height (the anti-"height-only" lesson: two same-height points can be desert vs snowfield). STAGE 6 SURFACE per-biome + slope + altitude surface colours (sand/grass/snow/rock/water). STAGE 7 FEATURES per-biome placements by seeded hash (trees / cacti / spruce / boulders). STAGE 8 SPAWN a valid spawn point (land, gentle slope) found deterministically. Pure integer, deterministic per seed. Stages 4/7 have toggles so gates can prove CAUSALITY per stage. license_tier: ORIGINAL
