 errors now distinguish credential/code rejection from session-cookie problems and
 a successful retry clears the old error. Both secure/default-cookie test modes
 are in CI; see `login-troubleshooting.md` and the latest validation section.
+The fix is source `4b483c2`; local 13 JVM, both 7-test cookie modes, 6 ordinary
+native UI tests, lint and all packages pass. Gitea build job 1071/run 666 (#11)
+passed and published the actual 0.2.1/code-3 APK; downloaded, verified and installed/
+launched on `emulator-5554`. Exact link/checksum are in `validation.md`.
+That CI-signed debug APK is now installed on the local emulator. Its certificate
+differs from the local Gradle debug key: before another local device-test run,
+remove only this synthetic preview package or use a fresh AVD. An install failure
+with zero tests must not be reported as a passing instrumentation run.
