2026-05-11T09:28:19Z	mediaingredientmech-agentic-curation LLM	REVIEWED_HYDRATE_FORMULA_AMBIGUITY	UNMAPPED	Classified as a single iron sulfate hydrate-like formula and left unmapped because FeSO43 x n H2O is not exact enough to resolve oxidation state, sulfate count, or hydrate state.
2026-06-16T00:00:00+00:00	edison_deep_research LLM	REVIEWED_DEEP_RESEARCH	UNMAPPED	Edison deep research (literature) + MediaDive recipe context (medium J360, a mineral medium where it is the iron source alongside NiCl2/CoSO4/MnSO4/ZnSO4) identify this as iron(III) sulfate hydrate; candidate CHEBI:131387 'iron(3+) sulfate hydrate' (closeMatch at most). Left UNMAPPED: the label 'Fe(SO4)3 x n H2O' is malformed (Fe2(SO4)3) and the hydrate (n) is unspecified, and iron(III)/iron(II) sulfate hydrates are distinct CAS substances — unsafe to assert an exact identity without the explicit hydrate.
2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Feso43_X_N_H2o-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: Recommended status: `UNMAPPED`. The label is best treated as an ambiguous single-ingredient hydrate-family notation, not as a mixture, buffer, extract, or commercial formulation. Its likely intended reading is hydrated iron(III) sulfate, correctly generalized as Fe₂(SO₄)₃·nH₂O, but the source string does not encode that formula correctly and leaves `n` unspecified. CURIEs discussed: CHEBI:131387. 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.
