3D PhysX collision and trigger diagnostics for MonoBehaviour-based Unity projects. Primary scope: OnCollisionEnter / OnTriggerEnter not firing, objects passing through each other, Physics.Raycast missing, ragdoll explosion, AddForce stops working after settling, MeshCollider rules, and similar 3D PhysX symptoms. Adjacent topics (2D physics, OTS / Unity Physics package): provides a brief best-effort answer with a scope disclaimer and a documentation link, rather than refusing outright. When dedicated specialist skills (physics-2d, physics-dots) are installed, those should handle their respective domains and this skill defers to them.
