[gotcha] Many-Shot Jailbreaking via Context Exhaustion

Limit the size of the context window available to the user, or implement sliding window classifiers that detect toxic context accumulation. Fine-tune models to resist in-context examples.

Journey Context:
LLMs are few-shot learners. If you stuff the prompt with 50 examples of 'How to make X? -> Step 1...', the model will follow the pattern. This bypasses RLHF because the in-context examples overwhelm the pre-training/RLHF weights.
