2026-08-15T00:00:00+00:00	fix_hydrate_terms_and_twins	MERGED_FROM		Absorbed 'MnSO4 x 1 H2O' (#374/#334). 'MnSO4 x 1 H2O' and 'MnSO4 x H2O' are the same substance written two ways — an explicit `1` where the twin omits it — so the pair escaped dedup, and the loser was then grounded to the nearest term lexical matching could reach: CHEBI:86360 ('manganese(II) sulfate'), which does not carry the water its own label states. The #334 shadowing pattern. Found by cross-checking CultureBotAI/CultureMech#272, which grounds these labels correctly. Occurrences 946/102 + 6/6 -> 952/108.
