MANUAL_CURATION
via MIM curation (#288)
A named multi-component preparation. Searched CHEBI, NCIT, MeSH, FOODON and ENVO by label and synonym: no term denotes it, and none could -- a preparation is not a substance. Takes the STOCK_SOLUTION convention: a kgmicrobe.ingredient: mint with no parent, because a multi-component mix does not narrow to any single compound (#288).

| 2026-08-07T03:02:00.533175+00:00 | issue_288_dedupe LLM | MERGED_INTO | REJECTED | Merged into kgmicrobe.ingredient:na-phosphate_buffer 'Na-phosphate buffer'; occurrences transferred. Tombstoned REJECTED, SSSOM rows dropped. Same preparation under two spellings differing only in punctuation ('Na-Phosphate-Buffer' vs 'Na-phosphate buffer'). Both were minted by the #288 batch, which compared labels against already-minted records but not against each other -- so it created two identifiers for one thing. |
| 2026-08-15T00:00:00+00:00 | fix_tombstone_pointers | REPOINTED_TOMBSTONE_IDENTIFIER | identifier kgmicrobe.ingredient:na-phosphate-buffer -> kgmicrobe.ingredient:na-phosphate_buffer (#360). This record was merged into 'Na-phosphate buffer' 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. | |
| 2026-08-15T00:00:00+00:00 | fix_tombstone_pointers | REFRESHED_TOMBSTONE_ONTOLOGY_ID | ontology_id kgmicrobe.ingredient:na-phosphate-buffer -> kgmicrobe.ingredient:na-phosphate_buffer (#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 'Na-phosphate buffer'. Provenance is unaffected: what the record used to assert is in this history. |
