LIVENESS_UNIFACE_DEFAULT_ENABLED is defined in config but never read by any runtime/production code path — only referenced in a test. No runtime effect (prod sets the backend explicitly).
Evidence: app/core/config.py:337 (definition); only other ref is tests/unit/infrastructure/test_liveness_runtime_wiring.py.
Fix: either wire the flag into the combined-mode backend default selection, or remove it.
