[gotcha] Single-turn safety filters miss attacks split across multiple conversation turns

Apply safety and policy checks to the full conversation context, not just the latest user message. Re-evaluate cumulative context before sensitive actions, use conversation-level classifiers, and consider resetting context or requiring re-authentication before high-risk operations.

Journey Context:
Many deployments run a moderation API only on the latest user message. An attacker can build rapport, establish false premises, or deposit instructions over several turns, then trigger them in the final turn. Each individual turn looks benign. This bypasses per-message filters because the harmful pattern only exists in the aggregate. The fix is to evaluate the entire context window for policy violations and treat instructions embedded earlier in the conversation as equally dangerous as instructions in the current turn.
