Filling tank with multiplicative partial drains: x grows at constant rate to saturation K, at Poisson rate drains to x*Uniform(0, 0.5). Random drain magnitude mirrors Forest Fire's variable fire-cluster sizes. Positive control for slow-build + sudden-drop phenotype with non-uniform drop magnitudes
Standard analysis sees: left-skewed; long-range memory (persistent); low-complexity (predictable, not noise-like); time-irreversible (slow rise, sharp collapse); low-dimensional. The atlas finds no named structure, but the source is distinctively extreme on S² × ℝ (Thurston):height_drift (+4.0z) — beyond what the standard bank predicts for it. It sits beside Stochastic Resetting Walk in the atlas (standard-bank rank 41) — a neighbor conventional features miss.
