| 2026-03-09T06:54:18.022301+00:00 | import_from_culturemech | IMPORTED | MAPPED | Initial import from CultureMech pipeline |
| 2026-04-05T19:52:11.703461+00:00 | fetch_cas_rn_from_pubchem | ADDED_CAS_RN | MAPPED | Added CAS-RN:219-452-7 from PubChem API via name lookup (Fucose) |
| 2026-04-18T00:00:00+00:00 | cbclaw_kg_microbe_sweep LLM | ADDED_SYNONYMS | MAPPED | Added 2 synonyms from kg-microbe P4.4 enrichment: 6-Deoxygalactose, Fuc |

| 2026-05-30T00:34:39.428633+00:00 | infer_roles_from_chebi_ancestry | ANNOTATED | Added media role: CARBON_SOURCE (confidence: 0.70) | |
| 2026-06-09T05:23:46.766808+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Fucose' -> 'fucose': synced to canonical CHEBI label (preferred_term 'Fucose' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): CARBON_SOURCE -> nutritional_roles.CARBON_SOURCE | |
| 2026-08-06T00:00:00+00:00 | issue_114_cas_audit LLM | CORRECTED | cas_rn 219-452-7 -> 7724-73-4. 219-452-7 is an EC/EINECS registry number (format NNN-NNN-N), not a CAS-RN — the same class of fetch_cas_rn_from_pubchem mis-assignment as Beef extract's 103-47-9 (=CHES) in #114. The replacement is this record's own CHEBI term CHEBI:33984's CAS dbxref, and that term's label matches the substance, so it is evidence rather than inference. The EC number is recorded here rather than discarded: it was correct information in the wrong field. | |
| 2026-08-27T03:16:39.518909+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 1/1 -> 2/2 (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).
