HA + independent Lean evidence · Research, not Alpha admission

P04-C12 — p04 c12

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

Exact named statement

1 = 1 ∧ (1 = 1 · 1 ∧ 2 · 1 = 2 · 1 · 1) ∧ (2 · S (2 · 1) = S (2 · 1) · (2 · 1) ∧ (2 · (2 · (2 · S (2 · 1))) = 2 · (2 · 1) · (2 · S (2 · 1)) ∧ 2 · (2 · (2 · S (2 · S (2 · S (2 · 1))))) = S (2 · (2 · 1)) · (2 · (2 · (2 · S (2 · 1))))))

Checked statement containment

These exact targets occur inside this certificate. These links summarize containment, not direct dependency arrows; the downloadable bundle records every private lemma and ordered edge.

Scope

complete exact subconjunction child

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