Pangu-Weather 1-hour ONNX (private catalogue package)
Real published Pangu-Weather 1-hour checkpoint, packaged without weight modification. The model is stateless and maps global 0.25° upper-air and surface fields to a one-hour forecast.

Graph contract
input: float32[5,13,721,1440], variables Z/Q/T/U/V and pressure levels 1000..50 hPa.input_surface: float32[4,721,1440], variables MSLP/U10/V10/T2M.output: float32[5,13,721,1440], one-hour upper-air forecast.output_surface: float32[4,721,1440], one-hour surface forecast.
inference_metadata.yaml is the hashless canonical workflow-SSA contract. Graph hash and source integrity are recorded separately in graph_report.json and provenance.json.

Run the saved deterministic request
pip install 'onnxruntime-gpu==1.28.0' 'numpy==2.3.3'
python run.py --request request.npz --output reproduced_output.npz --provider cuda
The checked-in output.npz was produced from request.npz on NVIDIA H200 using CUDAExecutionProvider. The request is a deterministic physically scaled baseline, not an observed ERA5 analysis. Exact timing and sampled forecast values are in runtime_output.json.
Annotated inference metadata
Review inference_metadata.annotated.yaml for inline explanations of this package's workflow, tensor/state/cache contracts, and fail-closed omissions. inference_metadata.yaml remains the canonical machine-authored contract; automated validation confirms both files parse to the same metadata object.
