Bound Lac Pavin graph to depth-associated genomic potential #1550

kb/communities/Lac_Pavin_Stratified_Lake_Community.yaml, PMID:36694212: genome-resolved metagenomics supports depth-associated metabolic potential, not measured flux or carbon fixation causing the methane-cycle and CPR/DPANN distributions. Oxygen co-varies with other geochemistry; CPR gene content has weak depth differentiation. RuBisCO II/III and III variants suggest nucleotide-associated CO2 incorporation, not complete Calvin-cycle autotrophy.

Repair all three existing nodes, drop both common-gradient arrows, qualify computational evidence and incomplete canonical participant coverage. Preserve positive genetic-potential observations. Add every-node/arrow decisions, history, tests and regenerated page. Close only after protected-main merge.

Source-based self-adversarial review, not independent approval. No new nodes/arrows or paid Edison submission.
