2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/S6_Medium-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: Recommended interpretation: “S6 medium” is a named culture-medium formulation, not a single chemical, salt/hydrate, buffer molecule, extract, or generic medium-component family. The strongest retrievable lineage is its use as an *S6 liquid medium for Bacillus subtilis***, with the formulation attributed to Fujita and Freese (1981). A later paper explicitly distinguishes S6 from tryptose 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.
