Fixed the readout: the effect packets are 3-4 edge TEXTURED quads (0x2c/0x42/ 0x0d edges + z + texz/texu/texv planes -- NO Gouraud colour, confirming the scene is textured). Two bugs in the first pass: (1) 0x2c edges were treated as 'accept both sides', turning every quad into a full-plane fill; (2) only 2-edge packets were caught, dropping ~3/4 of the geometry. render_battle.py applies the render_wide30 polygon-winding rule (inside = all-edges>=0 OR all<0) -> 78 polygons of 141 setups. Result (flat-per-polygon + depth): a geometrically coherent first-person scene -- sky at far depth, a ground plane ramping smoothly from horizon to foreground, a clean horizon line, upright structures. The perspective is consistent; this is real scene geometry, not the muddy u/v wedges of the first attempt. Surfaces still need texels (TXDN/M3) for their skin.
