| # king-1 — Forecast quality (process realism) | |
| **Lever:** better synthetic prior → lower geomean on held-out pool. | |
| **Code base:** t_smo_v5-style generator (NumPy/SciPy). | |
| **Key ideas:** | |
| - `weekly_demand` (~8%) for retail/load calendar structure | |
| - ARIMA-style correlated increments in `_integrated` | |
| - RBF/RQ spectral GP on 2L circulant embedding (no wrap artifact) | |
| - Prefix-causal measurement artifacts | |
| - Forecastable pulse timing | |
| **Score with:** | |
| ```bash | |
| cascade verify ./king-1 --chain-toml chain.toml | |
| cascade score ./king-1 --pool-dir ./my-heldout --device cuda --train-hours 0.5 --n-windows 256 | |
| ``` | |
