Result:
FAILED tests/test_nutricoach_v150_v15_safety.py::test_external_authority_transition_restores_predecessor_after_failure

Exact production failure:
gateway/platforms/task26_runtime_authority.py:126
ValueError: runtime authority pin is stale

Meaning:
The post-promotion rollback restored the predecessor credential bytes but did
not append a compensating predecessor QUALIFY event or regenerate the pin for
the final external registry/ledger heads.

Result:
PASSED tests/test_nutricoach_v150_v15_safety.py::test_external_authority_transition_restores_predecessor_after_failure

Verified:
- post-promotion rollback appends predecessor QUALIFY at N+2;
- the final predecessor pin matches the final paired heads and event count;
- production loader authorizes predecessor and rejects successor;
- successor runtime and credentials are absent after rollback.
