@react-native-firebase/messaging
native-seam only — the published @react-native-firebase/messaging JS runs unchanged against a NativeRNFBTurboMessaging seam read from the installed 26.4.0 iOS sources, modeled on the arm64 iOS simulator (never registered for remote notifications). Detox pushes with a gcm.message_id route through the notification bus to onMessage, onNotificationOpenedApp and getInitialNotification like RNFBMessaging+UNUserNotificationCenter. The opened event and one-shot initial notification are read from that native source but have no paired tap proof: on the iOS 27 scene life cycle Detox cannot deliver a tap response to RNFB (a launch tap is dispatched before RNFB installs its center delegate, and a background tap waits for an app delegate applicationDidBecomeActive that never comes). Estimates were reviewed against the installed native source by a second model.72%
