    Method and Limitations

    Static analysis only. CITT reviewed the code of this build without running the app, so runtime behavior was not observed. The findings below describe the analyzed build and may not reflect server-side controls or later versions. CITT makes no determination about compliance with any law or platform policy; it reports what the artifacts contain and cites the published guidance so a reader can compare.
