Pushed daily from the trading box, so each commit is a timestamped record of what was known when — the leak-free substrate behind the paper's replay experiments (`docs/EXPERIMENTS.md` in the [harness repository](https://github.com/PredictionMarketTrader/openthomas)). | file | what | lines / bytes | |---|---|---| | `data/nwp-guidance-and-settlements.jsonl` | as-of daily extremes from seven public NWP models (Open-Meteo previous-runs API) at leads 0-5, plus official settlements (ACIS / NWS CLI) | 29,022 | | `data/own-models.jsonl` | station-day extremes from OpenThomas' own GraphCast / Pangu inference runs, with issue timestamps | 5,600 | | `data/gencast-spread.json` | per station-day ensemble spread of the latest GenCast run (sigma multiplier input) | 3,296 | | `data/graphcast-tempseries.json` | coarse global 2m-temperature daily series from the latest GraphCast run | 112,989 | | `data/baseline-nbm.jsonl` | as-of NBM daily max/min per station (IEM MOS archive), the official-guidance baseline | 2,800 | | `data/baseline-gfsmos.jsonl` | as-of GFS MOS daily max/min per station (IEM MOS archive) | 2,800 | ## Frozen replay datasets and experiment results `replay/` holds the frozen decision-time rows (one JSONL per window, digest in the filename) and the experiment results scored on them. A row carries the settlement station and day, the baseline probability at the snapshot, the Kalshi bid/ask at that snapshot, and the outcome — never anything the agent could not have known at decision time. -

`lead` is days ahead: lead 1 for target day *d* is what the model published on *d − 1*. - NBM / GFS MOS baselines use the *d − 1* 12Z run, read from the IEM MOS archive as issued. - Own-model rows carry `issued_at`; the run that produced them is identified by that timestamp and the model name. *Paper trading. Nothing here is financial advice.*
