| 2026-08-13T00:00:00+00:00 | merge_minted_hydrate_duplicates | MERGED_FROM | Absorbed 'Sodium acetate·3H2O' (#321), which differs from this record only in notation the merge pass does not recognise as the same substance, so it escaped dedup and was grounded to the anhydrous parent. It had just been minted 'kgmicrobe.compound:sodium_acetate3h2o' on the false premise that ChEBI has no term for this hydrate — ChEBI label search for the trihydrate of the minted-off parent. Occurrences 6/6 + 2/2 -> 8/8. Raw label kept as a RAW_TEXT synonym. | |

The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).
