Neverblender is installed + enabled in this machine's Blender 4.0.2 config and confirmed working headless via the flake. Add generator/export_mdl.py: assembles each tile as a Neverblender-native model (AuroraBase dummy/tile, trimesh, single aabb walkmesh) in its own scene and calls scene.nvb_mdlexport to emit real ASCII <resref>.mdl + <resref>.wok for all 40 tiles. Walkmesh surfacemats via create_wok_materials() slot order (walkable Stone=4, Nonwalk=7) -> verified correct per tile (CP1 all 4, CN1 all 7, BR_1/CE_S mixed). flake.nix: add `export` app (nix run .#export -- <blend> <outdir> [CODE...]). AGENTS.md: record the Neverblender node/surfacemat facts and the kit's tools; note the slot-index (not material-name) surfacemat gotcha.
