2026-05-11T08:03:00Z mediaingredientmech-agentic-curation LLM CLASSIFIED_DEFINED_MEDIUM UNMAPPED Classified as a named MRS medium formulation and left unmapped rather than identity-mapping to a single component or generic medium parent.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/MRS_Medium-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended ontology decision:** retain the record as `UNMAPPED`. Use the label-only candidate **“de Man–Rogosa–Sharpe medium”** until a stable resource is verified to represent the formulation itself. Do **not** use `skos:exactMatch` to a generic culture-medium parent. With no verified target CURIE, the safest action is **no SSSOM row**. If a project requires non-identity class grounding, a ver 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.
