| 2026-08-18T00:00:00+00:00 | merge_aldehydo_duplicates | MERGED_INTO | Merged into CHEBI:47965 'N-acetylmuramic acid'; occurrences transferred. Absorbed 'n-Acetyl-muramic acid' (CHEBI:47966 aldehydo- form) into CHEBI:47965 (#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 (10597-89-4) 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. | |

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 'N-acetylmuramic acid'. Provenance is unaffected: what the record used to assert is in this history. |
