| 2026-08-13T00:00:00+00:00 | fix_hydrate_collapse | MERGED_FROM | Absorbed 'CoCl2 x 6 H2O', which sat on the anhydrous term CHEBI:35696 (#321/#334). Same substance in formula notation — a form the merge pass does not recognise, so it escaped dedup and was then grounded to the nearest lexical match. Occurrences 123/123 + 2265/50 -> 2388/173. Raw label kept as a RAW_TEXT synonym. | |
