| 2026-08-18T00:00:00+00:00 | merge_aldehydo_duplicates | MERGED_FROM | 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. Occurrences 1/1 + 10/10 -> 11/11. | |
| 2026-08-18T00:00:00+00:00 | merge_aldehydo_duplicates | FOLDED_MERGED_SYNONYMS | Folded 3 synonym(s) from 'n-Acetyl-muramic acid': ['(R)-2-acetamido-3-O-(1-carboxyethyl)-2-deoxy-D-glucose', '2-acetamido-3-O-[(1R)-1-carboxyethyl]-2-deoxy-aldehydo-D-glucose', 'aldehydo-N-acetylmuramic acid']. The merge kept the loser's LABEL but left its own synonyms on the tombstone. They still resolved via label_index, which publishes REJECTED rows, but the tombstone's SSSOM row was dropped — so they no longer reached KGX. These are real chemical names (D-Lyx, D-lyxo-pentose, the systematic forms), not notation noise. | |
