 acceptance result is claimed for the corrected projection yet.
 
+The load trace now splits base root expansion (`Graph`) from MSH/WEAR/MAT0/TEXM
+visual-dependency expansion (`GraphVisuals`) and enters `Assets` immediately
+before actual asset preparation. A controlled 60-second GOG first-root run of

 The same source-axis proof now applies to `TerrainWorld`: its `Land.msh` surface
 height query and `Land.map` areal/grid lookup use XY ground coordinates, return
 source Z height, and leave raycasts as full 3D intersections. The Part 1 and
