Locks in Decision 2 (Opaque + ClipMap → opaque indirect; AlphaBlend + Additive + InvAlpha → transparent indirect). Catches future refactors that drift the partition — silent visual regression otherwise (groups rendered in the wrong pass with the wrong blend state). Adds public static IsOpaquePublic shim on WbDrawDispatcher; the underlying IsOpaque stays private. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
