📝 Walkthrough

Walkthrough

The changes document the native passkey adapter for sign-in factors and session reverification. They add typed test coverage to verify that __internal_getPublicCredentials forwards distinct request options for sign-in and reverification. A mobile package patch changeset is included.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 04cc6

The Expo passkey second-factor support is otherwise localized, but its release metadata is incomplete, which may prevent the feature from being versioned and published correctly. Merge should wait for the changeset to be completed or explicitly waived.
