Qualify Z123 inferred division of labor and preserve measured LDPE outcomes #1639

CommunityMech:000342; PMID:42641428. Genomics plus proteomics suggest differentiation; the current SUPPORT and NICHE_PARTITIONING annotations overstate established resource partitioning. Qualify this inference without recasting proteomics as only gene content. Preserve 30-day weight/molecular-weight losses, GC-MS context and recombinant-enzyme evidence. No strain assignment, polymer-carbon assimilation/mineralization or full-dose matched synergy is established by the accessible abstract. Keep missing outcome-node work separate. Close only after protected-main merge.
