Remove workflow and coincidence arrows from the sequential SynCom-Chlorella slurry graph #1844

Finding

CommunityMech:000285, PMID:41794300. Construction and duration of stable operation are experimental context, not separate biological interactions causing the reported outcomes. Preserve the 60-day pollutant-removal endpoints, algal biomass/protein response versus BG11 and Rubisco/glutamine-synthetase transcriptional response. Remove the two workflow nodes and three remaining arrows that restate stability, shared treatment or co-occurrence. Removal does not establish cross-feeding, algal benefit does not establish neutral bacterial fitness, and transcript abundance does not establish enzymatic flux. Preserve the prior October2 graph repair; bacterial membership remains a separate existing #183 gap.

Primary Source And Review Scope

https://www.sciencedirect.com/science/article/pii/S0960852426004360
Four whole records and their existing graph evidence were read. Source coverage is indexed publisher abstracts/previews, plus the independently retrieved Chlorella EuropePMC abstract. The MetG2 Introduction and bounded section previews were read, not the full article. Direct publisher requests returned HTTP403; the public Crossref-advertised API links for the two CC-licensed articles returned HTTP400. No access bypass, whole-paper/supplement/figure-pixel certification or raw-data reanalysis.

All four matching issue bodies were read. Fresh all-state title/body dedup and scoped ignored/hidden local searches found no duplicate of this finding; PRs/comments were not exhaustively searched. Existing #1091/#1093 concern cache infrastructure, #184 scouting dedup, and #183 has a separate membership/access scope.
