[gotcha] Multi-turn 'Crescendo' attacks bypassing single-turn input filters

Implement stateful safety checks that evaluate the accumulated context and intent across turns, not just the latest user message. Monitor for gradual context shifts.

Journey Context:
Developers deploy input classifiers that reject obviously malicious prompts. Attackers bypass this by breaking the malicious request into a series of benign, seemingly unrelated questions. Each turn is safe in isolation, but the LLM gradually commits to the malicious persona or goal. Single-turn filters are fundamentally blind to the accumulated context that nudges the model over the safety guardrails.
