[[claim-lukyanov-integrators-115-organizations-40-cities-mid-1970s]] rests
entirely on one 2000 *Наука и жизнь* (*Science and Life*) article by O.
Solovyova, a Polytechnic Museum researcher — Tier 2, but a single source for a
specific quantitative claim (115 organizations, 40 cities, mid-1970s; digital
displacement specifically dated to "the early 1980s"). Per the sourcing floor,
quantitative claims need Tier 1–2 *and* no single unrefereed/single-outlet
source should carry a load-bearing number alone if a second one can be found.

**What would answer it:**

- The Polytechnic Museum's own primary page on the artifact — "Гидрогенераторы
  В. С. Лукьянова" by the same author, O. V. Solovyova — was located via the
  Wayback Machine
  (https://web.archive.org/web/20120328115234/http://rus.polymus.ru/?h=relics&rel_id=9&mid=&aid=9&aid_prev=9)
  but could not be read this session: the archived page is windows-1251
  encoded and rendered as mojibake by this session's extraction pipeline. A
  correctly-encoded re-fetch is the most likely single fix and would either
  corroborate (same author, same institution, closer to primary) or reveal
  this is the *same* underlying claim restated, not independent confirmation.
- The 2018 IEEE conference paper (Minina & Platonova, DOI
  10.1109/ENT.2018.00019, "Lukyanov's Hydraulic Integrator and Moor's
  Hydrocal") — bibliographic existence confirmed, full text unread (paywalled
  / JS-gated this session). If read, check whether it independently states a
  deployment count or displacement date.
- Any Soviet-era engineering-history source (a factory or ministry record for
  the Ryazan calculating-machine plant, or a period trade publication) giving
  an independent count of installations.

Kept open; the parent claim-note stays `seedling` and flagged
`[unverified-quant]` until one of these resolves it, or until a session
determines no second source exists and the figure should be marked as
irreducibly single-sourced rather than actively pending.

**2026-08-20 progress:** a follow-up capture re-fetched the nkj.ru primary
and searched broadly (Russian and English) for a second source. Result:
negative. Six pages carrying the figure were located — a Habr retelling, two
English hobbyist/history sites, Wikipedia's own external-link trail, and
several Russian aggregator mirrors (not individually fetched) — and every one
traced verbatim or near-verbatim to the same Solovyova sentence; none cited
an archival, statistical, or production record as origin. See
[[claim-lukyanov-115-figure-no-independent-source-located]] and its siblings.
Of the three candidate routes above, two remain unresolved: the Polytechnic
Museum's primary page is still unreadable (re-attempted this session with a
second, different fetch tool — same mojibake result, now pointing at the
Wayback snapshot's own encoding rather than any one tool's pipeline), and the
2018 Minina & Platonova IEEE paper remains paywalled/unread. Left **open**
rather than answered: the search was broad but not exhaustive (a genuine
institutional/archival record could still surface), and the two unresolved
routes are real, if currently blocked, paths to a positive answer.
