about

nx_worldgen_tuner.nx -- TEAM-OWNED verdict-targeted knob tuner (operator 2026-06-10 "build the team's capabilities to handle your callouts"). The refine loop auto-files a verdict row NAMING a weak axis; this organ picks that assignment up MECHANICALLY: read knowledge/status/worldgen_best.conf (preset, density, axis) coordinate-descend the generator's exposed knobs (river_depth, rill_depth, rill_radius, detail_amp) score = (worst-of-seeds grade, named-axis value) lexicographic bank winner -> knowledge/status/worldgen_knobs.conf (+ /tmp copy) on banked-knobs CHANGE -> auto-file one arc=PROCGEN pm row nx_worldgen_refine consumes the banked knobs each beat, so the tuned metric IS the gate metric. Verdict -> assignment -> tune -> re-verdict: the loop is closed with the 8-axis grader as referee, no LLM anywhere. TUNER lines -> stdout + /tmp/nishi_worldgen_tuner.log. Exit 0 = tuned (banked best >= starting score), 1 = regression refused. license_tier: ORIGINAL
