Separate Ogataea growth rescue from inferred sulfur exchange and endpoint bias #1653

CommunityMech:000450; PMID42318495. Preserve measured complementation and controlled initial-ratio effects. Single-strain supplementation supports asymmetric nutrient requirements, not measured met10-to-str3 homocysteine flux; paper explicitly calls for tracer/metabolomics. Correct implication that every ratio grows well or necessarily increases met10 fraction. FY31/FY34 are population-tracking strains, not automatically all screening genotypes. Preserve1151 canonical strain identities,1149 medium conditions and1150 dangling-outcome removal. Full primary main text read. Close only after protected-main merge.
