Bound SC2 maize biocontrol mechanisms to separate measured assays #1582

Maize_SC2_RootRot_Biocontrol_SynCom; PMID:42039819. Keep three observed endpoints: PDA inhibition, 14-day B73 height/fresh root mass under Pythium challenge, and Salkowski/CAS outputs. Neither competition, host immune activation nor reciprocal mutualism was isolated. Qualify suppression-to-growth mediation; auxin and siderophore assays are separate from plants and do not establish their necessity for protection. Report Salkowski estimates using an IAA calibration and CAS activity, not molecularly resolved siderophores or traced host delivery. Preserve external maize/Pythium participants (#888), incidental metal context (#887), and removal of the design pseudo-interaction (#889). Close only after protected-main merge.
