## 1. Qualify Declared Sign Data without an Existence Claim

Use only the supplied exact rational endpoints and declared signs in {-1,0,1}. Normalize rational results to reduced fractions with positive denominators, omitting /1 for integers. Sign data and width-halving do not establish root existence or convergence to a root; a separate theorem and its hypotheses would be required. left=0/1, right=4/1, left sign=1, right sign=1; require left<right. Give (left,right,left sign,right sign,at least one endpoint sign is zero or the endpoint signs are opposite?).

View answer and explanation(0, 4, 1, 1, No)

Check only the declared sign-bracket predicate. Opposite signs alone do not establish root existence without an appropriate additional theorem. This explicit finite/exact slice is neither a general theorem nor a judgment about a person. The exact result, retaining the requested order, is (0, 4, 1, 1, No).
