## Requirements

```json
{
  "python": "upstream-defined",
  "packages": [
    "pybullet (build matching the pinned upstream source)"
  ],
  "display": "Most examples connect to a PyBullet GUI or shared-memory server. Upstream pybullet_data models and adjacent helper files may be required.",
  "source_imports": [
    "pybullet",
    "pybullet_data"
  ]
}
```

## Invocation

```json
{
  "entrypoint": "python examples/pybullet/examples/jacobian.py",
  "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.
