| 2026-04-05T19:53:31.193170+00:00 | fetch_cas_rn_from_pubchem | ADDED_CAS_RN | MAPPED | Added CAS-RN:7783-28-0 from PubChem API via name lookup ((NH4)2HPO4) |
| 2026-04-18T00:00:00+00:00 | cbclaw_kg_microbe_sweep LLM | ADDED_SYNONYMS | MAPPED | Added 5 synonyms from kg-microbe P4.4 enrichment: 2-O-(4-deoxy-alpha-L-threo-hex-4-enopyranosyluronic acid)-alpha-L-rhamnopyranose, 2-O-(4-deoxy-beta-L-threo-hex-4-enopyranuronosyl)-alpha-L-rhamnopyranose, 6-deoxy-2-O-(4-deoxy-alpha-L-threo-hex-4-enopyranosyluronic acid)-alpha-L-mannopyranose, 6-deoxy-2-O-(4-deoxy-beta-L-threo-hex-4-enopyranuronosyl)-alpha-L-mannopyranose, 6-deoxy-alpha-L-mannopyranos-2-O-yl 4-deoxy-beta-L-threo-hex-4-enopyranuronic acid |
| 2026-04-19T01:05:11.460485+00:00 | cbclaw_sssom_review_fix | CORRECTED_ONTOLOGY_ID | MAPPED | Corrected ontology_id CHEBI:62476 -> CHEBI:63051 (old label: '(NH4)2HPO4', new label: 'diammonium hydrogen phosphate'). Reason: Previous CHEBI:62476 was a sugar — unrelated. Stripped 5 kg_microbe-sourced synonyms that were contaminated by the wrong CHEBI. |

| 2026-08-27T03:16:39.519583+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 27/27 -> 35/35 (media_count/total_occurrences), derived from distinct CultureMech recipe ids in the #337 occurrence table. The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).

Source: culturemech:output/ingredient_occurrences.tsv. | |
| 2026-09-10T04:48:50Z | mediaingredientmech-agentic-curation LLM | CORRECTED | MAPPED | Removed stale CultureMech note text from synonyms: Original amount: (NH4)2HPO4(Fisher A686). The resolvable vendor form remains as (NH4)2HPO4(Fisher A686). |
