 ## Installation
 
 **Recommended:** [uv](https://docs.astral.sh/uv/) installs fast, locks dependencies reproducibly, and matches how this repo is developed and tested (especially useful with heavy ML stacks like torch and transformers).

+* **Shared panel processing**: Forecasters reuse a common panel path for multi-series inputs (Chronos, TimesFM, Tafsut, and others), reducing redundant work and improving multi-model orchestration throughput.

 * **T0 beta support**: The shared [`T0`](../api/models/foundation/models.md#foundationforecast.models.t0.T0) wrapper now works with [`theforecastingcompany/t0-beta`](https://huggingface.co/theforecastingcompany/t0-beta) (~256M). Register it in gift-eval `models.yaml`; GIFT-Eval CI still replicates `t0-alpha` until leaderboard results exist for beta.

 ### Fixes
 
+* **FlowState frequency aliases**: Normalize pandas-inferred aliases (`h`, `6h`, `15min`, `MS`) before calling granite-tsfm `get_fixed_factor`, so hourly and month-start series work when `freq` is omitted.
+
 * **T0 / gift-eval CI**: Bump `tfc-t0` to `>=0.5.0` and call `T0Forecaster.predict(quantile_levels=...)` instead of the removed `quantiles=` kwarg. Fixes gift-eval Modal runs after PyPI resolved `tfc-t0` 0.5.0 alongside the t0-beta release.
