This interface computes the harmonic signal from primes using variable σ to detect destructive interference along the critical line ℜ(s) = 0.5.
For each detected local minimum, the tool reports the amplitude depth (σ-dependent, since σ weights each
prime's contribution) and the phase spread of the underlying components at that t (computed as
std(-(t·log p) mod 2π) across the primes used). Note that this phase formula does not depend
on σ at all — σ only rescales amplitudes, it does not change relative phase — so phase spread cannot be
used to argue that one σ shows "more genuine" interference than another. What differs between σ values is
simply which t-points cross the depth threshold, since the amplitude envelope changes with σ.
These are raw computed values, not a classification of interference "type."
