| 2026-09-21T21:33:25.379198+00:00 | mim_semantic_review_20260921 LLM | MERGED_INTO | REJECTED | Merged into CHEBI:4735 (EDTA). The source explicitly names EDTA; the parenthetical function does not turn the substance into the generic class of chelators. Original fields remain only on this excluded tombstone. Evidence: https://www.ebi.ac.uk/chebi/CHEBI:4735 |
| 2026-10-05T04:09:33.941715+00:00 | fix_tombstone_pointers | REPOINTED_TOMBSTONE_IDENTIFIER | identifier NCIT:C360 -> CHEBI:4735 (#799). This record was merged into 'EDTA' but kept its own old identifier, so a downstream lookup on this label resolved to nothing live. The target is the one named in this record's own MERGED_INTO entry; the chain was followed to the first live record. A tombstone exists to keep the loser resolvable. | |
| 2026-10-05T04:09:33.941715+00:00 | fix_tombstone_pointers | REFRESHED_TOMBSTONE_ONTOLOGY_ID | ontology_id NCIT:C360 -> CHEBI:4735 (#799). 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 'EDTA'. Provenance is unaffected: what the record used to assert is in this history. |
