37 source/integration tests, 23 real Android SDK verifier cases, SDK-valid padded APK CLI/MCP oracle and serial static checks passed. Hosted real-apk-signature passed. CI27pass7fail2skip7cancel; exact-main controls reproduce17source and14targeted existing-main assertions. NativeWindows/Mac/Node22 baseline gaps and canceled shards are documented.
