The remaining SonarCloud S5443 (publicly-writable directory) findings were the hard-coded /tmp screenshot paths in revoke_background_sync_access, which became "new code" once the surrounding function was edited. Replace every /tmp literal in the file with tempfile.gettempdir() (which S5443 accepts), eliminating the findings consistently rather than per-line.
