Noisy Sine (SNR 3 dB)

What It Is

Sine wave in Gaussian noise at SNR=3 dB (signal power ~2x noise) --- near the perceptual boundary where periodicity is barely detectable, transitional between C1 waveform and C5 noise regimes

Interpretation

Standard analysis sees: high-complexity (noise-like). The atlas finds no named structure, but the source is distinctively extreme on Boltzmann:spectral_gap_J (-2.5z) — beyond what the standard bank predicts for it.
