NOT.5:4.4 - Expose distinctions the target collapses

Look for different admitted source expressions with the same target expression. Ask whether the required operation gives different answers on them. If it does, the target alone cannot determine that answer: the translation has removed something the work needs. Section :5.2 makes this failure visible through cue order.

If every collapsed pair gives the same needed answer, the loss need not obstruct that question. For a claim about the whole admitted family, justify this independence over that family rather than infer it from a few pairs. MATH.2 supplies the mathematical construction through equivalence classes when that form is useful.

Include differences in assumptions, unfinished choices, references and reading context when they can change the answer. Equal visible strings can have different interpretations under different contexts. Conversely, two differently laid out diagrams can express the same directed structure when position has no role in their interpretation.

For several translation stages, follow the information needed by the final operation through each stage. A later, richer format cannot recover a distinction that an earlier stage removed unless another input supplies it.
