Separate Lotus SC3 host preference, priority effects and invasion association #1557

kb/communities/Lotus_LjSC3.yaml, PMID:34312531. Full primary Methods/Results identify SC3 experiment L as four weeks initial colonization followed by two weeks after reciprocal challenge. Early arrivals retain higher proportions; cognate-root invasion is greater and strain host-preference/invasiveness indices correlate. Neither that correlation nor the standing-community assay context establishes the two current directed arrows. Preserve all three observations with living-host evidence, relative-abundance and root/rhizosphere limits, and no selective niche-preemption or host-feedback mechanism claim. Do not conflate SC1 exudate experiments, SC2 comparisons, individual nodule isolates and SC3. Exact canonical strain roster requires reconciliation. Close only after protected-main merge.
