$$ Retail cdb trace v2 — find what records the collision when retail blocks the door.
$$ v1 had SPHEREPATH::set_collide which never fired (0 hits despite retail BLOCKING).
$$ Switching to the COLLISIONINFO family.
$$
$$ BP1: CPhysicsObj::FindObjCollisions (entry count)
$$ BP2: COLLISIONINFO::set_collision_normal (the "I got blocked" record)
$$ BP3: COLLISIONINFO::set_sliding_normal (slide-along response)
$$ BP4: COLLISIONINFO::add_object (which entity caused the collision)
$$
