Structure does not appear during smooth use. It appears during breakdown.
You won’t see the structure unless something goes wrong. It is revealed when action fails.

Failure reveals the real dependencies of the system.
A thing is not best understood as an isolated object with fixed properties, but as a structured space of possible human concerns and actions.
Breakdown reveals that structure, but concern and action define it in the first place.
For anything, you can try to map a space of possible concerns and actions
what concerns are primary?
what actions are possible?
what actions are blocked?
what matters if this fails?
what kinds of breakdown become visible from each concern?
