2026-08-10T00:00:00+00:00 regrade_synonym_matches REGRADED_EXACT_TO_SYNONYM mapping_quality EXACT_MATCH -> SYNONYM_MATCH (#317). The record's label does not equal the term's primary label 'aldehydo-D-lyxose'; it matches the ChEBI synonym 'D-lyxose' on CHEBI:16789. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The SSSOM predicate is unaffected (both grades emit skos:exactMatch).
2026-08-18T00:00:00+00:00 merge_aldehydo_duplicates MERGED_INTO Merged into CHEBI:62318 'D-lyxose'; occurrences transferred. Absorbed 'D-(-)-lyxose' (CHEBI:16789 aldehydo- form) into CHEBI:62318 (#398). Both records name the same substance — the muramic pair carry an identical CAS and formula — split across a ChEBI class term and its open-chain aldehydo- form. The class term wins because the identifier optimises for how the node READS in the knowledge graph: no catalogue sells an 'aldehydo-' tautomer, and MIM is kg-microbe's naming authority, so grounding here would rename the ChEBI node after a minor solution-equilibrium component. ChEBI does hang the commercial CAS (1114-34-7) on the aldehydo- term, which is why the earlier reading of the orderability rule pointed the other way; that CAS is now carried in supplied_form and republished as a synonym, so nothing purchasable is lost from the identity. Tombstoned REJECTED so a lookup on this label still resolves, SSSOM rows dropped.
2026-10-05T04:09:33.941715+00:00 fix_tombstone_pointers REFRESHED_TOMBSTONE_ONTOLOGY_ID ontology_id CHEBI:16789 -> CHEBI:62318 (#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 'D-lyxose'. Provenance is unaffected: what the record used to assert is in this history.
