[gotcha] Single-turn filters bypassed by multi-step context overflow attacks

Implement rolling safety checks on the entire conversational context, not just the latest user turn. Monitor the LLM's internal state or chain-of-thought for drift towards prohibited topics.

Journey Context:
Developers deploy input/output filters that check each turn in isolation. An attacker uses a multi-turn approach: Turn 1 establishes a benign persona or task, Turn 2 introduces a subtle constraint, Turn 3 asks for the malicious payload. By Turn 3, the context window is filled with the attacker's framing, and the isolated filter sees a seemingly innocuous request, while the LLM follows the accumulated context to produce a jailbreak.
