API coverage

No visual proof cases have been published for this package yet. The registry summary below describes what the compat layer implements.

Working

upstream GoogleSignin, GoogleSigninButton, statusCodes, and helper predicates run unchanged; configure, hasPlayServices, hasPreviousSignIn, getCurrentUser, addScopes, signInSilently no-saved response, getTokens signed-out rejection, clearCachedAccessToken, signOut/revokeAccess, and codegen native button press render through the RNGoogleSignin seam

Missing

real Google OAuth popup/redirect flow, token exchange, keychain-backed current user persistence, successful scope grants, One Tap / web credential support, and upstream iOS new-arch module provider registration in the RN oracle app
