| The phone app's scaffolding, in apps/mobile: Expo SDK 57 with Expo Router, Android first, with Chat, Code and Customize. It signs in with g1t's own OAuth 2.1 (PKCE, a client id that encodes "g1t for Android" and g1t://oauth/callback, so nothing is registered), keeps the server and credentials in the phone's keystore, refreshes the 30-day token a minute early and shares the single-use refresh between requests. A personal access token is the other way in, and a self-hosted g1t the other server. | 1 | import { useMutation, useQuery, useQueryClient } from "@tanstack/react-query"; |
