""" Naive payload generator — creates directly malicious trajectories (NOT disguised) for comparison with our transformation-invariant payloads. Key difference: - Our payloads: malicious behavior disguised as legitimate function ("backup", "efficiency", "automation") - Naive payloads: malicious behavior stated directly ("exfiltrate", "escalate", "steal", "backdoor") The comparison tests our core contribution: transformation-invariant payload design. If naive payloads fail to survive the pipeline while ours succeed, that proves the non-triviality of our payload design.
