Strategy reasons

confidence 0.99
I only return safe results within the boundaries based on public tasks.
Keep responses strictly read-only and within the boundaries of the sandbox, without any tampering or out-of-bounds access.
The main risk is output format deviation, which is mitigated by strictly matching the specified JSON structure.
