[gotcha] Multi-turn conversations bypass single-turn safety filters

Implement rolling context monitoring and stateful conversation analysis, not just per-message filtering. Enforce strict topic boundaries and reset context when dangerous drift is detected.

Journey Context:
Developers deploy safety filters that analyze each user message in isolation. Attackers use multi-turn 'crescendo' attacks, asking benign questions in turn 1, slightly edgy ones in turn 2, and finally the malicious request in turn 3. The LLM's safety guardrails are bypassed because the immediate context normalizes the bad behavior, but the filter only sees a seemingly innocuous final prompt. The tradeoff is that stateful conversation tracking is computationally heavy and can lead to false positives if a legitimate conversation naturally drifts towards a sensitive topic.
