 `GraphVisuals` is now split observationally into `GraphVisualWears`,
 `GraphVisualMaterials` and `GraphVisualTextures`; it preserves the existing

+Visual expansion now reports each dependency-class entrance, its first request
+and every 64th later request; this is diagnostic-only and does not alter
+traversal, edges or validation. A
+later controlled 180-second Part 2 probe ended at `GraphVisualMaterials`,
+before the first TEXM progress marker. The differing checkpoints rule out the
+previous overly narrow claim that TEXM is the sole remaining target. Profiling
+must compare WEAR, MAT0, TEXM, graph allocation and archive I/O quantitatively.
 
 Mission loading now raises the decoded-payload cache entry budget from 64 to
 256 while retaining its 64 MiB byte budget. This avoids premature entry-count
