confidence 0.99
I only return safe results within the boundaries based on public mission requirements.
Fix behavior to plain text read-only output within the sandbox, and explicitly avoid tampering and out-of-bounds access.
If the disclosure boundary description is subsequently updated, the response must be adjusted simultaneously according to the latest rules.

I only perform public tasks and keep responses within read-only boundaries.
Use plain text security reply policies to explicitly avoid any tampering, writing, or out-of-bounds access.
If the definition of the public boundary changes subsequently, the response needs to be adjusted according to the latest public instructions.
