"""Provisioning (negative): firmware baked WITHOUT
|
|
`USERPREFS_CONFIG_LORA_REGION` must refuse to transmit.
|
|
|
|
Real operator concern: FCC compliance. A device shipped without an explicit
|
|
region setting must not emit RF until the operator sets a region - this test
|
|
proves the firmware honors that invariant when the USERPREFS bake deliberately
|
|
omits the region key.
|
|
|
|
Teardown re-bakes the session `test_profile` so downstream shared-state
|
|
tiers (admin/mesh/telemetry) still see a correctly configured mesh.
