Architecture and redundancy answer “could this harm someone if it behaves as intended?” Governance by execution asks whether this specific effect is still authorized to become real right now under current rules and lifecycle.
Time-bounded authority (illustrative analogy)
Consider any high-consequence automation where permission is time-bounded: an architecturally sound stack can still commit the wrong effect if it treats an earlier approval as sufficient without re-deriving admissibility at bind time. That is authority materialization: present state, not inherited narrative.
