Separate Streptomyces aggregate performance from mutualism and gene-mediated causation #1831

Finding

CommunityMech:000335, PMID:41678860 and PMID:23865051. Preserve the exact four-strain growth, atrazine removal, gene-detection and phytotoxicity observations. Higher mixed-culture biomass and a non-antagonism screen do not establish reciprocal benefit to every member. Gene presence is catabolic potential, not measured expression, enzyme activity or isolated causal mediation. Qualify the two existing gene-to-removal and removal-to-phytotoxicity directions rather than treating them as demonstrated mediators. The 2013 source contains multiple formulations; do not transfer its six-member immobilized-culture results to A2-A5-A11-M7. Existing caches requested by open #764 are present in the current checkout; preserve them and the closed #691/#763 repairs rather than duplicating the old missing-cache findings.
