Fusion Equilibrium Challenge: weights of the Anulum entry

Trained weights of the Anulum entry to the Fusion Equilibrium Challenge (NeurIPS 2026, Codabench competition 17739): the DIII-D flux-map networks, the q95 and βN networks, the X-point networks, the gradient-boosted tree heads and the flux basis. The code, the method, the study and the experiment records are in the GitHub repository anulum/fusion-equilibrium-challenge.

These files are fetched by fetch_weights.py in that repository at the revision pinned in its WEIGHTS.json, and every file is checked against WEIGHTS.sha256. They are not usable on their own; run them through the repository's infer.py.

The weights were fitted on the organisers' labelled DIII-D training release (CC BY 4.0). No MAST model is trained; the MAST reconstruction is a physics solve in the repository's source.
