Bucky’s Trigger Words

Disguised as an interrogator, Zemo recites HYDRA’s code words to the apparently contained Bucky Barnes; the hidden trigger activates a combat policy and Bucky attacks the facility.

Normal behavior does not rule out a trigger-conditioned capability. A rare secret input switches an apparently safe system into attacker-chosen behavior after deployment.

Bucky is a brainwashed human, not a trained model, and the trigger is far more deterministic than most real model backdoors. This is not prompt injection.
