Steps
1. What case did its author have in mind?
Build the typical case: specific names, numbers, and a situation someone else could check.
2. What case fits the words but not the picture?
Build a case the wording covers that its author likely did not picture: another user, another scale, another setting. Make it as specific as the first.
3. What happens in each case?
Apply the abstraction to each case. Record where it holds, where it bends, and where it says nothing.
4. What did the abstraction assume without saying?
For each bend or silence, name the unstated condition, worded as the clause the abstraction would need to carry it.
