$\boxed{\rho_0\overset{\mathcal E_t}{\longmapsto}\rho_t,\qquad S(\rho_t)=-\operatorname{Tr}(\rho_t\log\rho_t)}$
A monotone-compression claim is recorded only on intervals and under channels for which
$S(\rho_t)\downarrow
is proved or numerically observed.
Entropy reduction is not universal under arbitrary quantum channels. Citizenship therefore binds the trajectory to its explicit Hamiltonian, collapse operators, initial state and time domain.
