Research direction

Start by reproducing the ONNX optimizer failure with a model larger than 700 MB and confirm where protobuf's 2 GB limit is encountered. Trace the optimizer's model-loading and serialization entry points; done means the issue's failure is understood and a supported path for processing the model is identified and verified.
