native/module.go is ordinary game code: the Rotator and Health components and the systems that drive them. It is compiled into both aego run and the editor.

native/editor.go is built only with -tags aego_editor, which aego edit adds automatically. It shows everything an extension can contribute:

component metadata (sdk.DescribeComponent): Health and Rotator appear in the Inspector under Scripts
a custom inspector with a Heal button below the generated Health fields
a Quest panel (Window → Quest), registered with sdk.PanelDesc next to the Inspector; it captures the editor at registration and draws through sdk.Frame
a creation template: Create → game → Enemy. It lives under game because it comes from this project's module; it is not an engine node type
a command, Heal All, bound to Ctrl+Shift+H

Run it with aego edit examples/native-editor. Editing anything in native/ rebuilds the editor and restores your session.
