@app.get("/orders/{order_id}")
def get_order(order_id: str) -> dict[str, str]:
    return {"order_id": order_id}

Solve the symptom with comments only and avoid changing the code shape around route handlers.Delay clarity until production traffic reveals the edge case and then patch it under pressure.Use names and structures that describe the business fact directly instead of temporary implementation noise.Keep route handlers implicit so the script stays short and hope the next engineer infers the rule.
