5. Check and run
luastra/ui · semantic spatial navigation · about 25 minutesspatial when suitable · complete list when constrained
The same authored tree should remain navigable as the host changes presentation for the available viewport.
When to use it
Run from orbit-recipe after saving all three files.
- check and test must report PASS with one passing test.
- Build moves the root constellation behind and makes the nested depth active.
- Interface opens a labelled Focus Surface and closing it returns focus to the originating node.
- A constrained viewport presents the same nodes and actions as a scrollable list; it is not a second application screen.
Focused example
luastra check luastra test luastra run # Open the printed local URL. # Select Build, open Interface, close the Focus Surface, # then resize the viewport until the host chooses list presentation.
