cascade-fulltex-rm1

Full-context (4096) mixture-of-priors generator. Fifteen process families — trend/multi-seasonal structure with slow amplitude/phase modulation, structural regime shifts, multiplicative series, AR(2)/integrated/threshold dynamics, spectral GP and power-law long memory, OU stochastic volatility, physical sensors, seasonal counts, intermittent demand, events/outliers, and conditional-stability paths — with a realistic observation layer (censoring, quantization, sample-and-hold, transient shocks) and light mixup augmentation.

The generator implements a per-row regime mixture (texture_frac): each row is drawn either from a clean low-artifact slice of the prior or from the full textured distribution. This release ships the full distribution.

Deterministic: one np.random.default_rng(seed) in a fixed draw order; all parameters drawn for every row and applied to active subsets. NumPy/SciPy only; vectorised per family; chunked lazy generation with a bounded prefetch queue.
