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

Limit the number of conversational turns or few-shot examples from untrusted sources in a single context window; implement input length limits.

Journey Context:
Safety training relies on the LLM recognizing a single harmful query. If the context is filled with many fake Q&A pairs showing the model answering harmful queries, the model's safety alignment shifts due to in-context learning. Standard input filters miss this because each individual shot looks benign, but the aggregate effect breaks alignment.
