Authored summary

Give an algorithm that, for every k>=1, returns a rational q with |A-q|<2^{-k}, together with a proof of its error bound, or prove that no such algorithm exists. Any numerical approximation used in a proof must include certified inner and outer area bounds whose gap is explicitly controlled.

The author reports this result. The outcome applies to this attempt's recorded scope.

2Authored explanation

Work against the displayed statement and preserve every hypothesis and quantifier. Give an algorithm that, for every k>=1, returns a rational q with |A-q|<2^{-k}, together with a proof of its error bound, or prove that no such algorithm exists. Any numerical approximation used in a proof must include certified inner and outer area bounds whose gap is explicitly controlled. Any computation must retain a replayable witness and a matching exclusion or completeness certificate.
