Synthetic demo • AI-assisted. Fictional discussion exercise with simulated dates. No real purchase, customer review, patient, expert identity or experimental result is represented.
Different numerals have different optical centres. A comparison mixes two dates and unequal magnification. How can the evidence be improved? This is an explicitly synthetic discussion case for reviewing evidence and documenting uncertainty; it does not describe a real purchase, patient or experiment.
Record format: question; response; source or method; limitation. Add a dated correction only if wording or evidence changes. WATCH-13912.
