Many applied vision systems pass training and fail in deployment because they treat perception as a one-shot prediction problem. A detector may work in clean frames, then lose identity under smoke, glare, vibration, partial occlusion, sensor dropout, malicious interference, or a road map that has simply become stale.
Anti-interference reliable action reframes the task: the system must know when its representation is dirty, cross-check multiple evidence channels, preserve identity continuity, replay failed claims, and enter a bounded recovery loop before acting with false confidence.
