| 2026-04-05T19:51:09.441784+00:00 | fetch_cas_rn_from_pubchem | ADDED_CAS_RN | MAPPED | Added CAS-RN:50-81-7 from PubChem API via name lookup (Ascorbic acid) |
| 2026-05-01T07:35:32.268686+00:00 | auto_classify_ingredient_type | AUTO_CLASSIFY_INGREDIENT_TYPE | set ingredient_type=SINGLE_INGREDIENT (CHEBI primary) | |

| 2026-05-29T23:35:36.110191+00:00 | extract_roles_from_synonyms | ANNOTATED | Added media role: VITAMIN_SOURCE (confidence: 1.00) | |
| 2026-06-09T05:23:46.726544+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Ascorbic acid' -> 'ascorbic acid': synced to canonical CHEBI label (preferred_term 'Ascorbic acid' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): VITAMIN_SOURCE -> nutritional_roles.VITAMIN_SOURCE | |
| 2026-08-27T03:16:39.518369+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 42/42 -> 65/65 (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).

| 2026-08-30T04:48:06.233536+00:00 | claude_culturemech_alias_backfill | ADDED_SYNONYMS | Added 1 CultureMech recipe surface form(s) that folded onto this record's published label but were absent from MIM's label index, so CultureMech could not resolve them: 'Ascorbic acid (Sigma)' (x1 CultureMech mentions).
