m_Waypoints/m_Speed/m_Loop/m_Resolution are what a scene file describes; asset::AssetManager::ResolveAssets (via asset::Resolver<PathFollow>) builds m_Path — a math::CatmullRomSpline through m_Waypoints, sampled at m_Resolution arc-length steps per segment — the first time it sees a non-empty m_Waypoints with no path built yet, same deferred-resolve shape as Sprite::m_Texture/Animation::m_Clip. m_Traveled/m_Finished are plain runtime state for whatever advances an entity along m_Path each frame.
