Summary by CodeRabbit

Bug Fixes
- Improved GitHub authentication reliability when device-authentication status cannot be determined.
- Prevented temporary token or service errors from unnecessarily interrupting session hydration.
- Preserved existing device-authentication sessions when their status is inconclusive.
- Added safer handling for authentication failures during session creation, token checks, and session cleanup.

📝 Walkthrough

Walkthrough

The authentication service now centralizes device-authentication detection through getDeviceAuthState(). Detection failures return undefined and produce warning logs. Hydration handles token retrieval failures without propagating errors. Session removal, token sufficiency checks, and device-auth session clearing now act only when the state is explicitly false. createSession also performs device-auth session persistence after storing sessions with rollback handling.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to b30c1

Device-authentication service or secret-read failures can leave stale sessions behind or remove valid sessions. These authentication lifecycle issues should be fixed before merge.

Include device-auth ID retrieval in the rollback scope.

getDeviceAuthSessionIds() propagates secrets.get() failures, but createSession() has already persisted updatedSessions and starts its rollback try block only before storeDeviceAuthSessionIds(). If the read rejects, the session remains persisted without a tracking ID. Later hydration removes only sessions listed in the tracking IDs, so this session can remain after device authentication ends. Wrap both calls in the rollback scope.

Guard session clearing on an explicit device-auth result.

getDeviceAuthState() returns undefined when isDeviceAuthToken() fails. Both runInteractiveFlow() and removeDeviceAuthToken() call clearDeviceAuthSessions(). Because the method skips only when the state is false, an unknown state still calls getToken() and removes every matching session, including a K8s-token session. Return unless isDeviceAuth === true.
