## 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": [
    "chrono",
    "cinttypes",
    "example_interfaces/action/fibonacci.hpp",
    "functional",
    "future",
    "memory",

    "rclcpp_action/rclcpp_action.hpp",
    "string"
  ]
}
```

## Invocation

```json
{
  "entrypoint": "Native main: rclcpp/actions/minimal_action_client/member_functions.cpp; build the target declared by the pinned upstream build files",
  "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.

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