| 2026-06-09T05:23:46.730732+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'BICINE buffer' -> 'N,N-bis(2-hydroxyethyl)glycine': synced to canonical CHEBI label (preferred_term 'BICINE buffer' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): BUFFER -> physicochemical_roles.BUFFER | |
| 2026-08-13T00:00:00+00:00 | merge_buffer_class_duplicates | MERGED_FROM | Absorbed 'Bicine', which sat on the structureless grouping class CHEBI:39065 (#320/#334). Same buffer under a trivial name; the class term carried no structure, so lexical matching had nothing to distinguish it from this record. Occurrences 2/2 + 3/3 -> 5/5. Trivial name kept as a RAW_TEXT synonym. | |

The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).
