Nav2 costmap cannot load a layer plugin. Missing package or wrong plugin name in parameters.

generic

92% success Install the missing Nav2 costmap plugin package
```
sudo apt install ros-humble-nav2-costmap-2d
```
90% success Verify plugin names in nav2_params.yaml match installed plugins
```
plugin_names: ['static_layer', 'obstacle_layer', 'inflation_layer']
```

85% success Check plugin type string matches exactly with ros2 plugin list

ros2 pkg prefix nav2_costmap_2d && cat install/nav2_costmap_2d/share/nav2_costmap_2d/plugins.xml

Common approaches that don't work:

Write a custom costmap layer from scratch 82% fail
Standard layers (obstacle, inflation, voxel) cover 90% of use cases; custom layers are complex
Remove the layer from configuration and navigate without it 92% fail
Removing obstacle layer means robot cannot see obstacles; will collide
