WHY IT NEEDS A POLICY

Why pwndbg_patch needs a policy

In debugger contexts, 'patch' typically means modifying binary memory or instructions at runtime (e.g., patching bytes in a process). This is a Write/Execute-level operation as it modifies the state of a running process or binary. Given the server context of exploit development and reverse engineering, patching likely overwrites memory or binary content.
