Noise dynamics and calibrated cycles
Connect finite GKSL dynamics and jump-time Gram matrices to phase averaging, asymptotic checking times, repeated-cycle error budgets, invariant truncations and numerical Choi calculations. Place calibrated-cycle data beside the dynamical and channel-composition inputs it uses.
