2026-04-05T19:53:43.688169+00:00	fetch_cas_rn_from_pubchem	ADDED_CAS_RN	MAPPED	Added CAS-RN:85-87-0 from PubChem API via name lookup (Pyridoxamine)
2026-04-09T00:32:50.689620+00:00	enrich_mim_cas_rn_batch	CAS_RN_ADDED	MAPPED	Added CAS-RN 85-87-0 from PubChem (via CHEBI:16410)
2026-04-18T00:00:00+00:00	cbclaw_kg_microbe_sweep LLM	ADDED_SYNONYMS	MAPPED	Added 1 synonyms from kg-microbe P4.4 enrichment: 4-(AMINOMETHYL)-5-(HYDROXYMETHYL)-2-METHYLPYRIDIN-3-OL
2026-04-19T07:39:23.955331+00:00	audit_mim_merge	MERGED_FROM_DUPLICATES	MAPPED	Absorbed 1 duplicate MIM record(s) into this one: Pyridoxamine_2.yaml. Synonyms, curation_history, and occurrence counts were unioned/summed; winner selected by highest occurrence count with preferred_term readability tie-break.
2026-05-01T07:35:35.965540+00:00	auto_classify_ingredient_type	AUTO_CLASSIFY_INGREDIENT_TYPE		set ingredient_type=SINGLE_INGREDIENT (CHEBI primary)
