Nice work! 😎
I didn't find anything of concern
Risk: 🟢 Low
Risk analysis
The highest scores are for security_impact and blast_radius. Security_impact is elevated due to the introduction of a new OAuth client secret configuration (GITHUB_OAUTH_CLIENT_SECRET) that must be handled securely, and the exposure of new endpoints (/v1/auth/device/refresh) that interact with GitHub's OAuth system. Blast_radius is moderate because the changes affect core authentication flows used by the Android client across potentially many users, and introduce new API surface area. Reversibility and operational_risk are lower concerns since the changes appear to be additive, include proper configuration guards, and maintain backward compatibility.

Risk: 🟢 Low
Risk analysis
The highest scores are for test_coverage and blast_radius. Test coverage is strong for the new OAuth flows but lacks regression tests for existing functionality. Blast radius is moderate due to new endpoints affecting Android client authentication. Security impact is low-moderate as client secrets remain server-side, but the expanded OAuth scopes introduce some risk.

actions/checkout in the workflow to set persist-credentials to false in their

- Around line 82-100: Update the Android workflow steps for unit tests, Compose
UI test compilation, lint, debug APK, and release APK to use failure isolation
with continue-on-error enabled, matching the backend Gradle build pattern. Add a
single “Enforce Android result” gate after these steps that explicitly fails
when any Android step failed, while preserving diagnostic and artifact
collection before the gate.
