-## What is not proved (from Section 7)
-
-- Instantiation at ℂ: connecting the ring-generic proof to Mathlib's complex numbers and matrix exponential.
-- A noise bound relating device error rates to sector leakage.
-- A truncated-oscillator encoding of genuine φ⁴, where the quartic is not an identity.
-- A Lean checker wired into CI, so every emitted certificate is checked on commit.
