| 2026-08-13T00:00:00+00:00 | merge_cas_conflict_duplicates | MERGED_INTO | Merged into CHEBI:17306 'Maltose'; occurrences transferred. Was on CHEBI:18167 ('alpha-maltose'); differs from the winning record only in the case of its first letter, and was grounded to the alpha anomer while the winner holds the anomer-agnostic term its CAS 69-79-4 points at. Tombstoned REJECTED, SSSOM rows dropped (#320). | |
| 2026-08-15T00:00:00+00:00 | fix_tombstone_pointers | REFRESHED_TOMBSTONE_ONTOLOGY_ID | ontology_id CHEBI:18167 -> CHEBI:17306 (#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 'Maltose'. Provenance is unaffected: what the record used to assert is in this history. | |
| 2026-09-09T00:00:00+00:00 | fix_kg_microbe_node_id_drift | CORRECTED | kg_microbe_node_id CHEBI:18167 -> CHEBI:17306 (#554). The compatibility node id lagged a same-prefix identifier correction; the downstream node id must match the curated identifier unless a record intentionally crosses CURIE prefixes. |
