## Requirements

```json
{
  "python": "Python/C++ toolchain compatible with pinned OMPL 2.0.2",
  "packages": [
    "OMPL 2.0.2 pinned source",
    "CMake/compiler and optional Python bindings/dependencies per selected demo"
  ],
  "display": "Build the selected native demo target or install matching Python bindings. Planning demos need their state-space/validity assumptions and optional meshes/data; a solution path is not automatically a controller.",
  "execution_domain": "computation-or-simulation",
  "source_imports": [
    "fstream",
    "ompl/base/StateSpace.h",
    "ompl/base/objectives/VFMechanicalWorkOptimizationObjective.h",
    "ompl/base/objectives/VFUpstreamCriterionOptimizationObjective.h",
    "ompl/base/spaces/RealVectorStateSpace.h",
    "ompl/geometric/SimpleSetup.h",
    "ompl/geometric/planners/rrt/RRTstar.h",
    "ompl/geometric/planners/rrt/TRRT.h",
    "ompl/geometric/planners/rrt/VFRRT.h"
  ]
}
```

## Invocation

```json
{
  "entrypoint": "Native main: demos/VFRRT/VectorFieldConservative.cpp; build the target declared by the pinned upstream build files",
  "notes": "Build the selected native demo target or install matching Python bindings. Planning demos need their state-space/validity assumptions and optional meshes/data; a solution path is not automatically a controller. 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.
