HA + independent Lean evidence · Research, not Alpha admission

SN002 — norm separation

Full irrationality (IR072/G121) remains open. Stable: 432. Alpha v35: 4,318. This checkpoint changes neither catalogue.

Exact named statement

∀ x. ∀ y. ∀ z. ∀ n. ∀ m. ∀ k. x · x + y · y = m + (x · y + y · x) → z · z + n · n = k + (z · n + n · z) → ¬(x = y ∧ z = n) → ∃ i. m + S i = 2 · k ∨ 2 · k + S i = m

signed norm integer gap not full IR032

None of these finite arithmetic statements closes an IR campaign parent. The analytic identification, interpolation and final positive irrationality certificate remain open.
