| 2026-08-20T00:00:00+00:00 | merge_identifier_collisions | MERGED_FROM | Absorbed 'Calcium Chloride' (#414). Both records held CHEBI:3312 while both were live, which MIM's own rule forbids — for a mapped record the identifier IS the ontology CURIE, so two live records on it assert that two ingredients are one thing. They are one thing: formula versus name for the same anhydrous salt; identical CAS 10043-52-4 and formula Ca.2Cl. Neither label mentions hydration, so this is not the hydrate/anhydrous trap that rules out the CuSO4 and FeSO4 families. 'CaCl2' wins as the label media actually use (502 occurrences against 15); the other survives as a RAW_TEXT synonym, so label_index still answers for it. | |
