 - 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.
 - Added a pure mobile vault configuration model that keeps vault storage app-local, distinguishes local-only vs remote-backed sync, and derives the required Git auth path from the parsed remote.
+- Extracted the mobile editor surface behind `MobileEditorAdapter` with a tested document projection so TenTap can replace the placeholder surface without changing shell navigation.
 
 ## 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.
