"""Sovereignty enforcement tests.

These tests implement the acceptance criteria from issue #94:
  [p0] Cut cloud inheritance from active harness config and cron

Every test in this file catches a specific way that cloud
dependency can creep back into the active config. If any test
fails, Timmy is phoning home.

These tests are designed to be run in CI and to BLOCK any commit
that reintroduces cloud defaults.
