Notes

1.1 adds inference-only long-period normalisation; this checkpoint is retrained on a corpus with GIFT-Eval-overlapping Chronos datasets removed. Training data per card: chronos_datasets (minus GIFT-Eval overlaps), GIFT-Eval Pretrain subset, synthetic data. Used in Toto 2.0 Family-and-Friends ensemble. The NX-AI/TiRex repo itself was not re-released as 1.1 (no such commit).
