Bound probiotic co-culture growth and supernatant cross-feeding inference #1628

Multispecies_Probiotic_MV_Luteolin_Consortium: full PMID42604006 supports increased co-culture viable counts and growth stimulation by partner cell-free supernatant. The Methods state plate counting without a member-resolved co-culture enumeration procedure; aggregate counts do not establish no antagonism toward every member. Retain positive growth and soluble-factor evidence, mark molecular cross-feeding PARTIAL and retain the existing MsrA causality gap. No new topology in this repair.
