 183/-- **DECOHERENCE FROM BIT ONE-STATEMENT THEOREM.**
 184
 185    Under the BIT-coupling decoherence model:
 186    (1) the canonical BIT carrier sits in the `(8.0, 8.1)` band;
 187    (2) substrate decoherence times follow `T₂(k) = T₂_0 / φ^k`;
 188    (3) cross-class ratios are exact `φ`-powers `φ^(k_b - k_a)`. -/
