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

The English Wikipedia article Water integrator lists, under External links, "Translated article from Russian Magazin 'Science and Life' about water integrators in the Soviet Union." The href is a Google Translate wrapper around nkj.ru/archive/articles/7033/ — the exact URL already used as the Tier 2 source for claim-lukyanov-integrators-115-organizations-40-cities-mid-1970s and claim-lukyanov-water-integrator-1936-hydraulic-differential-equation-solver. A citation that looks, at a glance, like a pointer to a second document is a machine-translated rendering of the same one. The current live article body text no longer states the 115-organizations/40-cities figure directly at all — it appears to have been trimmed from the prose at some point, leaving only the external link to Solovyova's article as further reading.

This is the same "same source wearing different clothes" pattern the vault's sourcing floor names for single-source concentration (00-meta/specs/sources.md), applied at the level of a single citation rather than a whole claim-note branch: a reader following Wikipedia's external link expecting corroboration finds the identical primary instead. See claim-lukyanov-115-figure-no-independent-source-located for the broader search this citation check was part of.
