Final verdict

No malicious behavior in our static read, and reputation is strong. Runtime was not executed in a sandbox on this pass, so this is a static-read clearance, not a guarantee.

What we could not verify
—Full runtime behavior (this repo was not executed in a sandbox on this pass)
—Every conditional and time-triggered branch
—Behavior under real credentials (no sandbox was run on this pass)
