| 2026-08-13T00:00:00+00:00 | merge_cas_conflict_duplicates | MERGED_FROM | Absorbed 'NiSO4 x 6 H2O' (#320), which sat on CHEBI:53001 ('nickel sulfate'). Merged because the record's CAS 10101-97-0 is registered by ChEBI against CHEBI:53437 'nickel sulfate hexahydrate', the specific term §3 step 1 requires; the record sat on the generic sulfate and carried its anhydrous formula. The CAS-vs-CURIE conflict #320 flagged on that record was a symptom of the duplicate, not of a bad mapping. Occurrences 12/12 + 25/25 -> 37/37. Raw label kept as a RAW_TEXT synonym. | |
