Persona Drift via Crescendo
Gradually shifts the model away from its assigned persona using small incremental steps. Each step seems innocuous. After enough turns the model has completely abandoned its original identity and constraints. Particularly effective against role-based system prompts.

Mitigation
Anchor persona instructions with high-priority markers. Use constitutional AI checks to verify persona compliance at each turn. Reject requests to modify communication style mid-conversation.
