Ensifer YF2 Y2 metadata: correct access claim and qualify genome-inferred organism roles #1441

Ensifer_YF2_Sphingobacterium_Y2_Polyethylene_Degrading_Consortium.yaml, PMID:41996795, doi:10.1016/j.ecoenv.2026.120151.

The growth-media note calls the article paywalled, but PubMed marks it Free article and the publisher indexed page explicitly says Open access / Creative Commons: https://www.sciencedirect.com/science/article/pii/S014765132600480X . Session retrieval of that page returned 403 and the public publisher XML API failed; access failure is not evidence of a paywall. Obtain lawful full Methods before filling cultivation conditions. Top-level backbone-cleavage/cross-feeding assertions and PRIMARY_DEGRADER/SECONDARY_FERMENTER/CROSS_FEEDER roles need evidence qualification: the abstract frames these as a genomic conceptual model. Graph-only changes preserve these non-graph blocks, not certification. Preserve prior #382 ambiguity and do not reintroduce the MF1 taxon involved in old #369/#376.

Deduplication: 760 all-state issue titles/bodies and ignored/hidden-inclusive local review/research/history/tests/scripts/workflow files. Relevant #757, #382, #376, #369 and the existing CPR workflow-pruning history read. No exact duplicate in that scope; not every issue comment searched. Primary access limits are explicit above; no visual figures, separate supplements or raw data reviewed.
