Bootstrap checksum-pinned ARM64 Node before Mac checkout, upload a dedicated installable native debug APK, collect AGP test output before UTP uninstall and reject stale/missing screenshots. Add five screenshot-output regressions and enforce native shipping-source invariants. Workflow lint, 10 runner and 8 JUnit verifier regressions pass; remote execution is not yet verified.
Verify the production manifest, system-only trust, development APK signature and unsigned release outputs before collecting local artifacts. Record source identity and hashes outside Git. Exercised successfully against the built APKs and AAB; collection must follow a clean-source build.
