2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/N-Z-Case-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** N-Z-Case is a **commercial/legacy hydrolyzed-casein preparation used as a complex nitrogen source in culture media**, not a single chemical, salt, hydrate, buffer, complete medium, or chemically defined formulation. A 1962 methods section identifies the punctuation-normalized label **“NZ Case”** as hydrolyzed casein supplied by **Sheffield** and uses it at 0.2% in a 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.
