## Requirements

```json
{
  "python": "ROS 2 Jazzy Python 3 / C++ supported toolchain",
  "packages": [
    "ROS 2 Jazzy",
    "rclpy/rclcpp and example package dependencies from package.xml"
  ],
  "display": "Build with colcon and source the ROS 2 overlay. These are action/executor/sensing building blocks, not completed robot manipulation tasks.",
  "execution_domain": "middleware",
  "source_imports": [
    "example_interfaces.action",
    "rclpy",
    "rclpy.action",
    "rclpy.callback_groups",

```

## Invocation

```json
{
  "entrypoint": "python rclpy/actions/minimal_action_server/examples_rclpy_minimal_action_server/server.py",
  "notes": "Build with colcon and source the ROS 2 overlay. These are action/executor/sensing building blocks, not completed robot manipulation tasks. No Hub preparation adapter or measured runtime success is claimed."
}
```

## Compatibility

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.
