[gotcha] Multi-turn jailbreaks bypass per-message safety filters by escalating across the conversation

Moderate the full conversation history, not the latest message. Maintain a safety state across turns, detect topic drift, and trigger review when benign scaffolding repeatedly moves toward harmful outputs.

Journey Context:
Single-turn classifiers and input guardrails assume each prompt is independent. Crescendo-style attacks start innocuously and progressively steer the model, exploiting the fact that refusal is usually evaluated locally. The same attack delivered in one turn is blocked; spread across ten turns it succeeds. Per-message filtering gives a false sense of security.
