This interface computes the harmonic signal from primes using variable σ to detect destructive interference along the critical line ℜ(s) = 0.5.
Minima of the harmonic amplitude function can appear for different values of σ. However, only at σ = 0.5 do these minima result from true destructive interference – that is, complete phase cancellation of oscillatory components. This phenomenon reflects a harmonic equilibrium where component vectors align in opposite phases, producing structured cancellation that corresponds to Riemann zeta zeros.
In contrast, deeper minima observed at other σ values (e.g., σ = 0.4) arise from asymmetric suppression, not equilibrium. These are not caused by full interference, but by dominance of certain frequency components. The interpreter distinguishes these by labeling only σ = 0.5 as "destructive interference (critical line)", and others as "partial interference" or "constructive accumulation".
Interpret amplitude with respect to phase structure, not numeric depth alone.
