Correct anode recipient and qualify CO2-return arrow in biophotovoltaic graph #1859

Finding

CommunityMech:000211. Anode electron transfer is not pairwise feeding of Synechococcus by Shewanella. Preserve the demonstrated D-lactate-to-anode path and separately observed cyanobacterial growth benefit. The existing reverse arrow has a device-separation description; replace it with explicitly hypothetical CO2 recycling proposed in Figure1, not proven mediation or electron return to cyanobacteria. Device separation is an abiotic compatibility intervention, not colonization facilitation. Distinguish temporal, spatial and replenished spatial-temporal formats; more-than-40-day operation includes medium replenishment and LB supplementation and is not an unsupplemented batch phenotype.

Evidence And Scope

https://pubmed.ncbi.nlm.nih.gov/31537786/
Whole three canonical records and all ten nodes/six existing arrows reviewed. Independently retrieved primary abstract for Halomonas; primary main text/captions for Shewanella, PHA, DNT and multi-omics; nitrate-study abstract and relevant coculture Results/Discussion. Exact read spans and limitations will accompany the decision ledger. No raw data or separate supplement/figure-pixel audit.

Fresh all-state issue title/body dedup and ignored/hidden-inclusive local searches performed. Read matching #1093/#258/#1851/#1669/#1606/#1605/#837/#836/#835 and related #529; no duplicate exact finding in that bounded scope. PRs/comments and all local historical reports were not exhaustively read.
