2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Poly_hexamethylene_carbonate-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: Recommended interpretation: the raw label denotes poly(hexamethylene carbonate), an aliphatic homopolycarbonate whose ideal constitutional repeat unit is `–O–(CH2)6–O–C(=O)–`. It is a polymeric single ingredient, not a hydrate, salt, buffer, extract, culture-medium family, or inherently a commercial mixture. No ontology CURIE was proposed. 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.
