Research direction

Start by running examples/auto_deploy/build_and_run_ad.py with the three configuration files named in the reproduction command, including world_size_8.yaml and num_hidden_layers_5.yaml. Trace the init_cache pass for openai/gpt-oss-120b on an H100 and determine why initialization does not complete; done means the command passes instead of freezing for over 30 minutes.
