No install-time, import-time, or runtime behavior indicative of credential theft, remote code execution, silent relay, backdoor, or dropper activity was observed in this package version. No lifecycle hooks performing network I/O, no.pth file side effects, and no top-level module code reading installer secrets or contacting non-first-party destinations were identified.
