Proposition: The 3/4 null does not apply to this larger class

If ${\mathfrak{N}}_{2,1,\mathcal{U}}$ permits the code of Theorem thm:quantumattainment and contains no compulsory intermediate disturbance, then

Thus the classical $3/4$ bound cannot be reused as an environmental-memory exclusion bound for that class.

Proof. A one-value classical environment is trivial. The winning Markovian qubit process belongs to the null.
