## Requirements

```json
{
  "python": "Python/C++ versions supported by pinned Drake v1.58.0",
  "packages": [
    "Drake v1.58.0 / pydrake from the matching release",
    "Bazel/C++ toolchain for native examples and optional LCM/Meshcat components"
  ],
  "display": "Native examples require matching Bazel targets and model data; Python examples may need Meshcat/LCM. Some examples communicate over LCM; inspect configuration before hardware use.",
  "execution_domain": "simulation-or-hardware",
  "source_imports": [
    "argparse",
    "gymnasium",
    "pydrake.common",

    "warnings"
  ]
}
```

## Invocation

```json
{
  "entrypoint": "python bindings/pydrake/examples/gym/play_cart_pole.py",
  "notes": "Native examples require matching Bazel targets and model data; Python examples may need Meshcat/LCM. Some examples communicate over LCM; inspect configuration before hardware use. No Hub preparation adapter or measured runtime success is claimed."
}

## Evidence

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

Fetched and SHA-256 checked this immutable source; statically parsed Python or located native main; verified pinned license bytes and checked explicit per-file license identifiers. No upstream code executed.

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