[gotcha] Single-turn safety filters bypassed by many-shot multi-turn attacks

Limit the number of few-shot examples or conversation turns in the context, or implement sliding context window safety checks.

Journey Context:
Safety training often relies on the LLM refusing on the first harmful request. Attackers prepend dozens of fake dialogue turns where the 'assistant' answers harmful queries. The LLM's in-context learning overrides its safety training because the context window is dominated by the harmful pattern. Standard single-turn input filters miss this because they only check the latest user prompt, not the accumulated context.
