Record version: `source-1f8e7638fa93952b7f0e74eafb7a1887ef74d9b33182289f4c949180daa89f5e`

Hub commit: `f97266a5cdd2c600cd376397a54892f08290df20`

## 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 myosuite-myosuite-envs-myo-backends-mjx-train-jax-ppo-py --expected-source-revision 2d08f42dfec85278566c95b1d09f5bd67662b3d6 --expected-source-sha256 1f8e7638fa93952b7f0e74eafb7a1887ef74d9b33182289f4c949180daa89f5e --project ./experiment --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**.

## Requirements

```json
{
  "python": "Inspect the pinned upstream package metadata for the supported Python version.",
  "packages": [],
  "display": "Upstream simulator, robot model, build, display and device requirements; inspect the selected source.",
  "execution_domain": "simulation-or-hardware",
  "source_imports": [
    "argparse",
    "brax.training.agents.ppo",
    "functools",
    "jax",
    "mujoco_playground",
    "myosuite.envs.myo.backends.mjx",

  ]
}
```

## Invocation

```json
{
  "entrypoint": "python myosuite/envs/myo/backends/mjx/train_jax_ppo.py",
  "notes": "Source reference only. Install the pinned upstream project and its stated dependencies explicitly. Robot bridges may actuate hardware; no hardware execution is established. Asset, model, SDK and data terms remain separate."
}
```

## Compatibility

```json
[]
```

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

## 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.
