Not a list of things it is bad at. Seven places where the map simply ends — each one the direct shadow of a mechanism you have already watched work.
The pattern
A bigger model shifts none of these lines. Each one is answered by adding a mechanism from the outside — a lookup, a store, a check, a person.
So what
You can now predict where it will fail before you watch it fail — which is the whole difference between being impressed by it and being able to use it.
