• No source independent of O. Solovyova's 2000 account corroborates the Lukyanov '115 organizations / 40 cities' deployment figure

• Two English-language derivative accounts of the Lukyanov integrator drop the '40 cities' detail and diverge to 'used up to the 1990s,' consistent with transmission drift rather than independent knowledge

• English Wikipedia's citation for the Lukyanov water integrator resolves to a Google-Translate wrapper around the same nkj.ru document already cited as this vault's Tier 2 source

• Does a second independent source corroborate the '115 organizations in 40 cities' Lukyanov-integrator deployment figure (mid-1970s) and the early-1980s digital-displacement point?
