Bound Oak Ridge field selection and redox potential to their actual assays #1652

CommunityMech:000136; PMID30523276/22988623. Preserve controlled isolate tolerance and its supported inference to field enrichment, without universal genus resistance or nitrate-selective toxicity. Correct uranyl versus free uranium(6+) grounding, remove niche-partitioning/cross-feeding overclaims and the tolerance-to-redox-guild arrow that joins different studies without flux evidence. Main tolerance paper read completely; field clone paper remains abstract bounded (normal publisher403 respected). Preserve field-community scope and prior650/258. Close only after protected-main merge.
