StructBench checkpoints: notch_beam_2d_impact
Blessed reference checkpoints of the StructBench benchmark notch_beam_2d_impact, published with code release v0.4.0 (ADR-0074 clause 8). Each folder holds what running and checking the model needs: the registered checkpoint, the resolved config.json, the normalisation statistics when the model uses them, the metrics-<split>.json of the scored splits, and a SHA256SUMS covering those files. The results registry that reads these numbers is the benchmark's landing page, docs/benchmarks/notch_beam_2d_impact.md.

Use
Download a folder and evaluate it with the StructBench CLI, which rebuilds the simulator from the folder's own config.json (the evaluation overwrites the downloaded metrics-<split>.json; keep a copy to compare):
hf download StructBench/notch-beam-2d-impact --revision v0.4.0 --local-dir bundles
structbench-train --mode rollout --out bundles/<bundle> --data-root <canonical cases>
Verify a file against SHA256SUMS before trusting it. Code and benchmark definitions: https://github.com/qilinli/StructBench (Apache-2.0).
