Bound HP15 marine-snow graph to assay-specific aggregation and TEP evidence #1880

Finding

CommunityMech:000259: the 2011 rolling-tank aggregation effect does not establish a universal HP15 requirement. The 2014 climate-perturbation study reports no bacterial effect on total TEP, aggregate volume or the aggregate-size/sinking relationship. More TEP did not mean more aggregation. TEP is not itself a demonstrated directed feeding event; carbon-export interpretation is not niche partitioning. Preserve measured chemotaxis-mutant attachment impairment while qualifying its mediation of aggregation. Chitin-fibre caption evidence does not establish chemical identity of all TEP.

Three whole canonical records read. Fresh primary abstracts and DOI metadata for nine source identities; complete extracted main bodies for the 2014 climate, HP15 genome and 2020 partitioning papers; full extracted 2011 aggregation, 2017 recognition and 2017 consortium PDFs. Selected figures visually inspected. The 2018 diel main body was read from existing curator text, not independently retrieved full text. Chemotaxis is bounded to the abstract; MEPS full PDF returned HTTP 401 and was not bypassed. No new publication bodies or cache changes.

All-state issue title/body dedup and ignored/hidden-inclusive local searches were recorded. Nine matching existing issues were read; historical PR comments were not exhaustively searched.
