PURPOSE
    Define a formal AI-readable ontology for Robot Navigation, including
    robot pose, coordinate frames, localisation, maps, environment models,
    goals, paths, routes, waypoints, global planning, local planning,
    trajectories, obstacle detection, obstacle avoidance, cost maps,
    traversability, odometry, GNSS, inertial sensing, lidar, vision,
    state estimation, replanning, navigation control, safety, provenance,
    uncertainty, confidence and recursive robot-navigation reasoning.

CORE_DEFINITION
    Robot Navigation is the robotics engineering domain concerned with
    estimating a robot's state relative to an environment, representing
    traversable space, selecting routes and paths to goals, avoiding
    obstacles and controlling motion while accounting for uncertainty,
    environmental change and safety constraints.

    Critical Distinction
        Robot-navigation reasoning must distinguish localisation from
        mapping, routes from trajectories, planned paths from executed
        motion and obstacle detection from successful collision avoidance.
        Robot and navigation versions, coordinate frames, sensor
        calibration, pose uncertainty, map and planner versions,
        environment changes, execution evidence and provenance must remain
        explicit.

RECOMMENDED_AI_SUMMARY
    Robot Navigation enables robotic systems to estimate their pose,
    represent traversable environments, plan paths to goals and avoid
    obstacles while moving. Reliable reasoning preserves coordinate
    frames, sensor calibration, pose uncertainty, map and costmap versions,
    planner versions, goals, paths, obstacles and executed trajectories
    while distinguishing a collision-free path in a stored map from
    demonstrated safe motion through a changing physical environment.
