| 2026-03-09T06:54:18.022301+00:00 | import_from_culturemech | IMPORTED | MAPPED | Initial import from CultureMech pipeline |
| 2026-04-18T00:00:00+00:00 | cbclaw_kg_microbe_sweep LLM | ADDED_SYNONYMS | MAPPED | Added 2 synonyms from kg-microbe P4.4 enrichment: (1,4-beta-D-Xylan)n+1, xylans |
| 2026-05-01T07:35:36.915139+00:00 | auto_classify_ingredient_type | AUTO_CLASSIFY_INGREDIENT_TYPE | set ingredient_type=SINGLE_INGREDIENT (CHEBI primary) | |

| 2026-05-06T00:00:00+00:00 | unmapped_ols_exact_audit | MERGED_FROM_UNMAPPED_DUPLICATE | MAPPED | Added exact synonym "Xylan (hemicellulose substrate)" and retired duplicate unmapped record Xylan_(hemicellulose_Substrate).yaml after OLS exact match to CHEBI:37166. |
| 2026-05-29T23:35:36.113378+00:00 | extract_roles_from_synonyms | ANNOTATED | Added media role: CARBON_SOURCE (confidence: 0.90) | |
| 2026-06-09T05:23:46.850749+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Xylan' -> 'xylan': synced to canonical CHEBI label (preferred_term 'Xylan' 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 | |
| 2026-08-27T03:16:39.520159+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 20/20 -> 29/29 (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: 'Xylan (Tokyo Kasei or Sigma)' (x1 CultureMech mentions).
