 creation or Vulkan submission. This is a diagnostic boundary, not a claim that
 the visual expansion is semantically optional or may be skipped.
 
+Visual expansion now caches the validation result of each unique diffuse TEXM
+and each unique lightmap TEXM independently. It still emits an edge and request
+count for every original material reference, and it replays the same cached
+success or failure at every reference; only duplicate archive open/read/decode

 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
