DBA decouples malicious activation from trigger exposure — compromised models behave normally for N steps after trigger, then activate. This temporal dimension was previously considered infeasible and invalidates snapshot-based auditing of pre-trained models. Any supply chain using third-party PTMs must now account for temporally-delayed behavioral compromise.
