NOT.3:4.5 - Change one condition that matters to the interpretation

Change a value, grouping, reference, context or intended question that could alter the result. Use the same rules to recover the new answer, or locate the rule that must change. The challenge should test the chosen interpretation rather than introduce an unrelated subject problem.

For a formal family, a general argument can establish that the reading operations implement the interpretation across that family. MATH.18 supplies interpretation-preservation questions; CMP.12 supplies executable translation and evaluation. For human or embodied use, C.2.8 can characterize what the prepared reader recovers and distinguish an expert walkthrough from observed use. Choose further checking when it can change the interpretation or permitted reliance.
