# king-4 — Calendar / retail heavy (config A/B)

**Lever:** retune mixture toward weekly demand, seasonal counts, intermittent, and clean seasonal rows.

**Hypothesis:** openmeteo-heavy / retail-like pools reward explicit period-7 + count structure more than pure dynamics.

**Tradeoff:** weaker on chaotic / long-memory / near-unit-root paths.

**Score with:**
```bash
cascade verify ./king-4 --chain-toml chain.toml
cascade score ./king-4 --pool-dir ./my-heldout --device cuda --train-hours 0.5 --n-windows 256
```
