 - Wrapped the mobile root in `GestureHandlerRootView`.
 - Added a tested compact gesture mapper and `SwipeSurface` wrapper so phone panels can transition through swipe gestures while keeping panel behavior in the reducer.
 - Re-tested the iPad simulator path; the app now launches in Expo Go on `iPad Pro 13-inch (M4)`.
+- Added a pure mobile Git remote parser that codifies the auth choice: GitHub remotes use the GitHub OAuth App path, arbitrary Git remotes use the SSH-key path.
 
 ## Next Action
 
 Continue Phase 2 with the next mobile shell slice:
 
 1. Dismiss or suppress Expo Go's first-run tools modal during simulator QA so screenshots capture the app without the overlay.
-2. Add the storage/auth abstraction skeleton behind the mobile vault repository.
+2. Connect parsed Git remotes to a mobile vault configuration model.
 3. Begin the TenTap editor spike behind a `MobileEditorAdapter` once the shell/storage boundary is stable.
