2026-05-11T08:14:56Z mediaingredientmech-agentic-curation LLM REVIEWED_POLYMER UNMAPPED Classified as a single polymer ingredient and left unmapped because the surface form lacks CAS/stereochemistry support for safe merge to the existing poly(3-hydroxybutyric acid) mapped record.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Poly-ß-hydroxybutyric_acid-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** an ambiguous legacy polymer label, most likely intended to denote **polyhydroxybutyrate (PHB), P(3HB), or poly(3-hydroxybutyrate)**. Reviews use PHB, P(3HB), and poly(3-hydroxybutyrate) for a bacterial intracellular storage homopolyester and distinguish it from the broader polyhydroxyalkanoate family. However, the submitted form does not explicitly state the hydroxy 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.
