| 2026-08-20T00:00:00+00:00 | merge_identifier_collisions | MERGED_FROM | Absorbed 'MgCl2x 6 H2O' from CHEBI:6636 (#414). the identical label with one space missing, yet grounded to different terms: the 2,285-occurrence spelling sits on magnesium dichloride HEXAHYDRATE and the 7-occurrence spelling on the ANHYDROUS salt. The label says '6 H2O' either way, so the anhydrous grounding is simply wrong. Merging both fixes that grounding and clears CHEBI:6636's collision, leaving only 'MgCl2' on the anhydrous term where it belongs. | |
