about

nx_procgen_scene_gate.nx -- Gx/PROCGEN: a COMPOSED procedural nature scene + paired GROUND-TRUTH SEGMENTATION label map (the Infinigen / digital-twin shape). Unifies the generators: 1D-FBM rolling-hill horizon + sky gradient + seed-placed procedural trees (trunk + canopy) + one canon-proportioned human, all in one frame; a parallel buffer emits a flat-coloured per-pixel CLASS map (sky/ground/tree/human) = the label an ML/twin pipeline consumes. Integer/sovereign/asset-free, seed-diverse. HONEST: stylised, not photoreal -- it proves COMPOSITION + LABELS (two named GAP axes), not fidelity. D001 MIGRATION 2026-09-02 (procgen PG19): hand-rolled PASS/FAIL prints, a fails counter and sys_exit(1) replaced by gv_check per tooth and gv_verdict, so the exit code IS the verdict; measurements, thresholds and the PNGs are unchanged. license_tier: ORIGINAL expect_exit: 0
