Investigated the user-reported divergence (a solid-red cone in the 0x0007 dungeon
that retail doesn't draw). Narrowed by elimination:
- geometry, not VFX (survives particles-off)
- object 0x70007055 / Setup 0x020019F0, physState=0x1C — NOT NoDraw/Hidden
- its distinguishing texture 0x06006D65 (DXT1 256x128) DECODES tan/opaque offline,
identical to a neighbour decoration (0x020019EE / tex 0x06006D63) that renders fine
- not a per-instance tint (hook dropped)
=> the red is introduced at runtime in the WB bindless texture-array upload/sampling
path (a #105-class "samples undefined until flushed" / layer-handle misassignment),
possibly lighting. Both WB-render-migration and sky/lighting are FROZEN phases, so the
fix awaits explicit sign-off. Full diagnosis + reusable diagnostic approach in the issue.
