Verify before changing more
When a route or tool behaves unexpectedly, inspect the resolved profile before adding another provider or changing unrelated settings:
fabric status --deep
fabric doctor
The status output is the better starting point for runtime questions; the configuration file alone may not show defaults, profile selection, or the effective provider route.
