    "mujoco-mjx (follow pinned tutorial install cells)",
    "jax and accelerator-compatible jaxlib",
    "notebook dependencies listed in source_imports"
  ],
  "display": "The upstream notebook requires a GPU-accelerated Colab runtime and JAX/MJX setup. Inspect notebook install cells before running.",
  "source_imports": [
    "IPython.display",

## Invocation

```json
{
  "entrypoint": "Notebook: mjx/tutorial.ipynb",
  "notes": "Inspect source arguments and local paths first. Run from the pinned upstream checkout as documented; examples may open a window, run continuously, or expect existing data. No success-rate or task-completion guarantee is attached."
}
```

## Compatibility

```json
[]
```

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

## Evidence

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

Fetched the exact source file, parsed Python/imports or located its native main/notebook cells, and inspected the repository license.

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