Mesh Collider Not Working in Unity? Convex, Falling Through & the Rigidbody Error

Mesh collider falling through the floor, a doorway that turned into a solid wall, or the "Concave Mesh Colliders are not supported when used with dynamic Rigidbody" error? Shown with real Unity 6.5 footage: what convex and non-convex mean to PhysX, why a convex hull fills holes (and the 255 triangle limit), tunnelling with Discrete vs Continuous Dynamic collision detection, and why compound colliders are usually the best answer for moving objects.
