## Access

Fetch the pinned repository, verify this source checksum, and use upstream installation and invocation. This record does not install or execute code.

Optional inert file retrieval: `python /PATH_TO_SKILL/scripts/rsh.py fetch-source isaac-groot-scripts-deployment-benchmark-inference-py --project ./experiment --expected-source-revision dac54b313160c201c450f97df0fd74ebd379c892 --expected-source-sha256 7487f8d5b85a4a4a35a2dc46521c28a3fc0516638b77851c0137c925c5924173 --json`. This verifies one file, preserves provenance and never installs or runs it. See [source-file retrieval](https://hub.superfastrobotics.com/source-files.md).

Hub preparation adapter: **false**. Runtime verification: **not_run**.

## Invocation

```json
{
  "entrypoint": "python scripts/deployment/benchmark_inference.py",
  "notes": "Read the pinned source and workflow setup. CUDA/TensorRT environment and configured model/data required as declared by deployment docs; benchmark results were not produced by this census. External checkpoint/model-server requirement; code license does not establish checkpoint license. No weights fetched. No environment was resolved and no source was executed."
}
```

## Compatibility

```json

Missing environment fields remain unknown. Source discovery labels do not establish robot compatibility.

## Evidence

Level: **source_reviewed**. Runtime verification: **not_run**.

Verified exact source, applicable license and author/setup document bytes at a full Git commit; parsed the Python AST and reviewed this guarded operational entrypoint and its explicit license notices. No upstream code, installation, robot command, dataset, mesh or checkpoint was executed or loaded.

Source review and contributor reports do not establish task completion. Preserve upstream attribution and licenses.
