| ## Provenance |
|
|
| - Trained on `data/processed/dk1_panel_{train, val}.parquet` (FX-corrected 2026-05-16) |
| - Seeds: `[13, 42, 137, 1729, 31415]` (frozen project-wide) |
| - Train cutoff: 2025-02-28 UTC |
| - Val window: 2025-03-04 β 2025-04-30 UTC (post-EAM regime) |
| - Per-seed artifacts at `models/forecaster/b2_ewma/seed-<n>/`: |
| - `model.pt` / `model.npz` β weights |
| - `stats.pkl` β train-stat normalization (mean/std/target stats) |
| - `val_preds.npz` β quantile predictions on val |
| - `metrics.json` β pinball / coverage / ACI numbers |
| - `aci_state.json` β final ACI state (Ξ±_t, buffer) |
