2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/B-glucan_from_yeast-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: Recommended interpretation: a source-defined polysaccharide family/preparation, not a single chemical, salt, hydrate, buffer, or uniquely specified commercial formulation. The normalized label should be “β-glucan from yeast” or “yeast β-glucan.” In the common Saccharomyces cerevisiae context, the material is dominated by β-(1→3)-D-glucan chains together with β-(1→6)-linked branch CURIEs discussed: MESH:D001812. Recorded as provenance only — no grounding applied from this run. Edison's recommendations are deliberately conservative, and a plausible identifier promoted by a mechanism that never decided anything is what #203 and #263 exist to undo. Any CURIE above is a curator's to accept or reject.
