The narrow conductor-local primitive large-sieve input #

The full-cutoff primitive large sieve bounds a retained conductor block by the same L + Q² constant as the full block. That statement cannot create the R⁻¹ diagonal needed after deleting conductors d ≤ R. This file therefore freezes the missing analytic input at the square-ledger level, before any unsquared high mean is formed.

Coefficient energy of one primitive prefix row.

    The precise missing analytic strengthening of the primitive prefix-maximal large sieve. It is a square-ledger statement for an arbitrary coefficient row. In particular it neither mentions nor assumes a Vaughan high mean.

    The L/R diagonal is the only new information relative to the existing full-cutoff theorem; the lane is unchanged.

      Square-ledger extraction. Once the actual row geometry supplies L * energy ≤ N² and energy ≤ N, the local primitive large sieve gives the required N/√R + Q√N scale.
