Power payment for the same large-common-modulus mask #
Here T is the upper beta endpoint. The saving depends on a positive lower
power bound for both lengths, not just on the common-modulus threshold.
The original progression sum and its zero mode keep exactly the same mask.

The original and zero-mode terms are paid together on an arbitrary submask of the large common-modulus condition. The threshold is uniform in all changing data. The positive beta order is removed in the dyadic API.
