Sawtooth wave --- linear ramp with discontinuous reset, rich in harmonics (1/n Fourier decay)
Standard analysis sees: rich, high-entropy values; long-range memory (persistent); strongly periodic; low-complexity (predictable, not noise-like); time-irreversible (slow rise, sharp collapse); volatility-clustering (bursty); low-dimensional. The atlas finds no named structure, but the source is distinctively extreme on Symplectic:flux_sign_persistence (+5.4z) — beyond what the standard bank predicts for it. It sits beside Rossler Attractor in the atlas (standard-bank rank 33) — a neighbor conventional features miss.
