 **Data-access rule:** models consume `public/` files only. `hidden/` exists for local scoring on the dev seed, never as model input. Eval seeds (added later) ship public-only; their truth stays with the maintainer.
 
-A `reference/` tree holds the four reference models' submission-format predictions (`reference/<model>/<cell_slug>/`, one directory per corner of the instruments × text grid); their scores and descriptions live in the GitHub repo's `submissions/` directory, and the estimator code is in its `baselines/` directory. A completed datasheet is at `DATASHEET.md`.
