NOT.2:4.5 - Construct and read the cases that challenge the rule

Build the intended expression from the declared parts. Recover its grouping, resolve the references and identify the component boundaries. Then perform the required operation with the supplied interpretation.

Use a contrasting case that could reveal a mistaken rule. Depending on the chosen construction, change the grouping, reuse a name inside another scope, exchange two ports or introduce a shared component. Select the challenge because its interpretation can change the result.

If two readers still recover different arrangements that matter to the work, locate the point of divergence. Add or repair the corresponding delimiter, reference rule or connection convention. If both arrangements express the intended equivalence, make that equivalence part of the scheme instead of forcing one arbitrary drawing.
