theorem Phenomena.Questions.Exhaustivity.termType_exhaustivity_data_consistent : (termTypeExamples.all fun (d : TermTypeExhDatum) => d.termType.exhaustive == d.exhaustive) = true

Data consistency: for each concrete datum, if the term type predicts exhaustivity then the datum confirms it, and if the term type is non-exhaustive then so is the datum.

This is a per-datum verification over our @cite{groenendijk-stokhof-1984} examples, not a universal claim (arbitrary TermTypeExhDatum values can violate any pattern).
