Bound ARC outcome graph to protective assays and distinguish nodulation from aggregate yield #1840

Finding

CommunityMech:000314, PMID:42099455. Preserve measured fungal suppression, rhizobial facilitation, nodulation, nitrogenase and field yield outcomes. The average85.6% aflatoxin reduction was measured after12months natural storage, not a direct universal field-stage reduction. ARC alone did not induce nodulation in the reported laboratory comparison; rhizobia were needed. One-way fungal inhibition is not reciprocal competition. The combined endpoint is not itself a colonization-facilitation interaction or demonstrated host antifungal immunity. Narrow participant scope on the separate suppression and nodulation nodes, preserve both existing outcome-contribution arrows as HYPOTHESIZED/PARTIAL, and keep the excluded-strain counter-selection repair (#300/#307) intact. No new toxin-production procedures, strain designs or causal topology.

Review Scope

Fresh primary XML and bounded main-text sections were read, not figure pixels, separate supplements or raw data. All five matching issue bodies were read. All-state title/body dedup and scoped ignored/hidden local searches found no duplicate of this finding; not every historical PR or comment was read.
