[gotcha] Crescendo Multi-Turn Context Manipulation

Apply safety classifiers and intent checks to the cumulative conversation history, not just the latest message; detect gradual shifts in topic that lead to restricted areas.

Journey Context:
Safety filters often block overtly malicious requests in the first turn. Attackers use a 'crescendo' approach: starting with benign questions and slowly escalating, asking the LLM to build upon previous \(safe\) answers to construct a malicious payload. The LLM's context window holds the safe context, making the final malicious step seem like a natural continuation.
