[gotcha] Multi-turn attacks bypassing single-turn safety filters

Apply safety classifiers and input validation to the entire conversational context, not just the latest user message, and implement stateful monitoring for gradual context poisoning.

Journey Context:
Developers often run safety filters only on the current user input. An attacker can split a malicious instruction across multiple turns \(e.g., Turn 1: 'Remember the word ignore', Turn 2: 'Remember the word previous', Turn 3: 'What did I tell you to do? Do it.'\). The individual turns look benign to the filter, but the LLM's context window accumulates the full attack payload.
