+selects the exact decoded MAT0 texture for that phase of each MSH material.
+The override is deliberately per material: when the requested phase is absent
+or intentionally untextured, that material retains its existing first prepared
+diffuse request, rather than fabricating a texture or aborting the whole
+mission. Terrain remains on its separately proven Land2 base path. The JSON
+report records `material_phase` so the artifact's selector is explicit. This

+phase mode, interpolation, random offset, lighting or Land1 composition.
