# cascade eval pool — lagged public reveal

Daily snapshots of the **held-out evaluation pool** used by the
[cascade](https://github.com/TensorLink-AI/cascade) subnet, built from the
[tsbench-forge](https://github.com/tensorlink-dev/TSBench-Forge) live catalog of
real public time series across the 7 GIFT-Eval domains.

**Each snapshot is revealed 24h AFTER it was used for scoring** (`as_of` is a
closed UTC day). Because the pool rotates daily, a released snapshot is always
for a round that is already scored — it lets anyone **reproduce the leaderboard**
without exposing the round currently in play.

## Layout

```
snapshots/<YYYY-MM-DD>/          one folder per revealed day (as_of)
  <series_id>.npy                float32, freshest context_length + horizon points
  metadata.json                  {series_id: {freq, seasonal_period, domain, source}}
  provenance.json                build config (context_length, horizon, builder_version)
```

Scoring is identity-agnostic: MASE uses `seasonal_period`, CRPS/WQL use the
values + a model's quantiles, and the KOTH cluster-bootstrap groups windows by
`source`. Re-cut windows of `context_length + horizon`, forecast the horizon,
and the metrics reproduce byte-for-byte.
