DATABASE_MATCH
via Edison LITERATURE (PaperQA3) + local CHEBI verification
MES monohydrate. The report quotes a peer-reviewed materials section naming 2-(N-morpholino)ethanesulfonic acid monohydrate with CAS RN 145224-94-8 and recommends adding exactly that number. No hydrate-specific ontology term exists: CHEBI:39005 is the ANHYDROUS acid, a different substance by formula weight, so it is the narrowMatch parent rather than the identity.

| 2026-05-11T09:28:19Z | mediaingredientmech-agentic-curation LLM | REVIEWED_HYDRATE_AMBIGUITY | UNMAPPED | Classified as a single MES hydrate-like buffer ingredient and left unmapped because no exact local ontology identity for the hydrate form was verified. |
| 2026-08-06T00:00:00+00:00 | edison_literature_identity LLM | ANNOTATED | Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/MES_Hydrat-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: - **Recommended status:** `UNMAPPED` CURIEs discussed: CHEBI:39010. 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. | |
| 2026-08-07T00:00:00+00:00 | edison_cas_enrichment LLM | ADDED_CAS_RN | Added cas_rn 145224-94-8 (2-(N-morpholino)ethanesulfonic acid monohydrate) from Edison literature research: the report's own recommendation is to "Add the source-backed preferred name, exact monohydrate synonyms, CAS RN 145224-94-8, and hydrate-state annotation", citing a peer-reviewed materials section that names the monohydrate and associates it with that number. Enrichment only — the mapping status is unchanged, because a CAS identifies a substance without supplying an ontology term. Applied only because the report AFFIRMS the number for this record's own substance: the same scan pulled CAS numbers out of five other reports that forbid them outright (HBO3, α-D-Glucose monohydrate, Larchwood xylan, Sigmacell alpha Type 50, dextran Mw ~1,270), because a CAS printed in a rejected-candidate row looks identical to one in a conclusion. | |
