  "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.",

```

## Invocation

```json
{
  "entrypoint": "python examples/conveyor_belt/conveyor_belt.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.
