ContactPair

Set the physics World's contactSelection to authored to use its enabled ContactPair entities as the complete ordered list of collision candidates. Each pair holds normal Zero references to bodyA, bodyB and world. solverOrder sets order; entity ID breaks ties. Reversed pairs are distinct and may both be present, as in the native character solver. Identical directed duplicates and self-pairs are rejected. An empty authored list generates no contacts.

Collision enabled flags, static/static suppression and collisionGroup still apply. This selects candidates only; native geometry and material handling determine the actual contacts. Default automatic selection remains unchanged.
