theorem AVenhance.Infra.Section4.iterate_smallness_of_budget_enlargement {e d D : ℝ} (hd : 0 < d) (hdD : d ≤ D) (h : e ≤ (4 * D ^ 3)⁻¹) :
e ≤ (4 * d ^ 3)⁻¹

Source smallness persists when the universal budget constant is enlarged.

theorem AVenhance.Infra.Section4.iterate_source_frequency_eq {e : ℝ} (he : 0 < e) (γ D : ℝ) :
D * e ^ (-1 - γ / 2) = D / e ^ (1 + γ / 2)

Normalize the source frequency to the length scale in the downstream statements.
