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.
Add an ephemeral HTTPS proxy and standards-shaped RS256/S256-PKCE test IdP around the unmodified upstream checkout. Require unlocked devices and nonempty, failure-free JUnit evidence. The extended API 35 suite passes all seven cases, including native Blob/file transfer, session recreation, outage recovery, isolated OIDC and back navigation; eight evidence-verifier regressions also pass. API 37 and real-provider/device validation remain release gates.
