Sharp interval: P̃₊ (even, real) vs cos(2πy), and P̃₋ (odd, imaginary) vs −sin(2πy)
P̃₊ even (Re)
cos(2πy)
P̃₋ odd (Im)
−sin(2πy)
Stage M2 — Lee–Oliver–Pozdnyakov (arXiv:2307.00256), Theorem 1.1. The Gauss-sum-normalized average χ(p)/τ(χ) over primitive even/odd characters, ordered by prime conductor, converges to an exact density: sharp interval → cos(2πy) (even) / −i·sin(2πy) (odd). Zero external data — characters, Gauss sums, and primes are all computed from scratch. Renders emitted JSON only.
