[gotcha] Single-turn safety filters bypassed by many-shot context priming

Cap the number of few-shot examples or conversational turns allowed in a single context window, or implement context window monitoring for repetitive Q&A patterns that precede a malicious query.

Journey Context:
Safety filters are often trained on single malicious requests. If an attacker pads the prompt with dozens of benign Q&A pairs \(many-shot\), the LLM enters a pattern-completion mode. The sheer volume of benign examples dilutes the safety training, causing the model to answer the final malicious query just to complete the pattern. Limiting context length or detecting this repetitive priming is necessary.
