Drivers (connections)
The Studio Drivers surface does CRUD on connection resources.
Two binding models
- Catalog — connection holds the endpoint; tag has
behavior.connectionId+behavior.point. The compiler produces a fullTagSourceviaresolve_connections. Connection does not enter the snapshot. - Inline —
behavior.source(host + point together). Cannot be used with the catalog.
