2026-05-11T07:59:07Z mediaingredientmech-agentic-curation LLM REVIEWED_EDTA_COMPLEX UNMAPPED Classified as a single manganese(II)-EDTA complex and left unmapped because no exact local ontology term for Mn(II)-EDTA was verified; generic EDTA or manganese mappings would not preserve complex identity.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/MnII_x_EDTA-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: **Recommended interpretation:** a **1:1 manganese(II)–ethylenediaminetetraacetate coordination entity**, conventionally called **Mn(II)-EDTA** or **Mn-EDTA**. It is not generic EDTA, free Mn²⁺, MnSO₄, or an arbitrary manganese chelate. Structural/solution literature represents the complex as `[Mn(EDTA)]²⁻` and, when inner-sphere water is shown explicitly, `[Mn(EDTA)(H2O)]²⁻`; the latter establishe 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.
