Summary
dist_of_disj_compact_pos: requireE.NonemptyandF.Nonempty. WithE = ∅,set_dist E F = sInf ∅ = 0, contradicting> 0.UnsignedMeasurable.aeEqual/aeLimit/comp_cts: add everywhere-nonnegativity hypotheses (Unsigned g,Unsigned f,Unsigned φ).UnsignedMeasurablerequires global nonnegativity, but the old statements only gave it a.e. or not at all (e.g.φ = · - 1).Root cause
Issue #517: statements were false as formalized because hypotheses were too weak for the conclusion types.
