Ontology mapping

Primary identifier: UNMAPPED_0179
Notes: Imported from CultureBotHT (compounds_to_cas.csv (no CAS-RN)). No CAS-RN or CHEBI mapping available; curator review needed. Reviewed on 2026-05-11 as a specific cobamide variant; not identity-mapped to generic cobamide or cobalamin.

2026-05-11T08:12:15Z	mediaingredientmech-agentic-curation LLM	REVIEWED_COBAMIDE_VARIANT	UNMAPPED	Classified as a single cobamide-family ingredient and left unmapped because no exact local ontology identity for the 5-methylbenzimidazolyl lower-ligand variant was verified.
2026-06-17T00:00:00+00:00	deep-research-ingredient-edison LLM	RESEARCHED_IDENTITY	UNMAPPED	Edison/PaperQA3 deep research: discrete cobamide variant (lower ligand = 5-methylbenzimidazole; "5-MeBza-Cba"); no stable CHEBI/CAS, and mapping to cobalamin would be chemically incorrect at the lower-ligand level. Kept UNMAPPED.
2026-08-06T00:00:00+00:00	edison_literature_identity LLM	ANNOTATED		Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/5-methylbenzimidazolyl_Cobamide-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: ## Executive recommendation — Retain `UNMAPPED`. The label denotes a chemically meaningful, discrete cobamide variant defined by a 5-methylbenzimidazole lower ligand, but it does not specify the variable upper axial ligand. No exact stable ontology CURIE, CAS Registry Number, or unique source-backed formula was verified. Therefore, create no SSSOM identity row at present. In particular 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.
