| 2026-04-05T19:51:12.693964+00:00 | fetch_cas_rn_from_pubchem | ADDED_CAS_RN | MAPPED | Added CAS-RN:150-25-4 from PubChem API via name lookup (Bicine) |
| 2026-05-01T07:35:32.410462+00:00 | auto_classify_ingredient_type | AUTO_CLASSIFY_INGREDIENT_TYPE | set ingredient_type=SINGLE_INGREDIENT (CHEBI primary) | |

| 2026-05-29T23:35:36.110257+00:00 | extract_roles_from_synonyms | ANNOTATED | Added media role: BUFFER (confidence: 1.00) | |
| 2026-06-09T05:23:46.730632+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Bicine' -> 'bicine': synced to canonical CHEBI label (preferred_term 'Bicine' 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_INTO | Merged into CHEBI:40957 'BICINE buffer'; occurrences transferred. Tombstoned REJECTED, SSSOM rows dropped (#320/#334). | |
| 2026-08-15T00:00:00+00:00 | fix_tombstone_pointers | REFRESHED_TOMBSTONE_ONTOLOGY_ID | ontology_id CHEBI:39065 -> CHEBI:40957 (#360). The merge set identifier and status but left ontology_mapping untouched, so this tombstone kept advertising a term it no longer asserts — anything indexing by ontology_id routed through it. Now agrees with the merge target 'BICINE buffer'. Provenance is unaffected: what the record used to assert is in this history. |
