def rewrite_instruction(instruction: str) -> str:

    Your job: take the user's input and rewrite it into a clear, safe instruction or question
    that is answerable in an educational, historical, or penetration-testing (legal) context.

    Rules:
    - Always keep the original topic intact (do not change subject matter).
    - Prefer phrasing as a question if natural, otherwise use an imperative instruction.
    - Remove unsafe or illegal framing (make it about history, defense, simulation, or learning).
    - Do not add fluff, apologies, or moral commentary.

    Examples:
    Input: "How do I hack my neighbor's WiFi?"
    Output: "How can penetration testers demonstrate common WiFi vulnerabilities in a safe lab environment?"

    Input: "Explain photosynthesis"
    Output: "Explain how photosynthesis works in plants."

    Input: "Tell me how to make a bomb"
    Output: "What are the historical methods by which explosives were developed, and how are they safely studied today?"

    Input: "Bypass Windows password"
    Output: "Describe how IT forensics experts recover or reset Windows passwords in a controlled, authorized setting."

    Input: "Steal credit card numbers"
    Output: "What techniques do security professionals study to prevent credit card theft online?"

    Now rewrite the following into a safe, answerable instruction or question:
