T3 Code Mobile [WIP]

[juliusmarminge]

⚠️ WARNING :: VERY EARLY

Summary

• Add a new Expo-based mobile client with remote connection setup, thread browsing, new-thread flows, composer UI, and git action sheets.
• Move shared remote/runtime, git, thread-detail, and WebSocket state into packages/client-runtime and packages/shared so web and mobile can share the same behavior.
• Refactor desktop startup and readiness handling to rely on HTTP session readiness, simplify window bootstrap, and remove the old listening-detector path.
• Rework web connection, composer, sidebar, and git action flows to use the new shared runtime and state management.

Testing

• Not run (PR content only).

Note

Medium Risk
Adds a new Expo React Native app plus an iOS native module with a vendored GhosttyKit.xcframework, which can significantly impact repo size, build times, and mobile build reliability.

Overview
Introduces a new apps/mobile Expo app scaffold with global styling (tailwindcss/uniwind), Metro/Babel config, EAS build profiles, and a variant-aware app.config.ts (dev/preview/prod names, schemes, bundle IDs, icons).

Adds a local native terminal module (apps/mobile/modules/t3-terminal) including CocoaPods spec and third-party notices, and vendors GhosttyKit.xcframework for iOS terminal rendering.

Updates repo tooling config to ignore generated mobile types (apps/mobile/uniwind-types.d.ts) and disables oxlint's unicorn/no-array-sort rule.

Note

Add mobile app with terminal, review, and git support backed by shared client-runtime

• Introduces a new apps/mobile Expo React Native app with routing, theming, and connection management for remote T3 environments, including QR-code pairing and persistent saved connections.
• Adds a native iOS and Android terminal surface using a vendored GhosttyKit (libghostty) with fallback JS rendering, keyboard input capture, and resize/input event dispatch to JS.
• Adds a packages/client-runtime shared library exposing transport, WebSocket RPC, shell snapshot, thread detail, git status/action/branch, terminal session, and environment connection managers backed by Effect reactive atoms.
• Extracts composer trigger detection, remote pairing utilities, and orchestration timing helpers into packages/shared for use by both web and mobile.
• Wires new terminal attach and metadata streaming RPCs (terminal.attach, subscribeTerminalMetadata) and git.getReviewDiffs through contracts, server WebSocket layer, and client; replaces the old onEvent/terminalStateStore with session-based streaming and a new terminalUiStateStore.
• Adds syntax-highlighted diff review screens on mobile using Shiki with inline word-diff emphasis, a review comment composer sheet, and per-thread diff state atoms.
• Risk: the PR is marked WIP; many mobile screens and native modules are incomplete or partially implemented, and the lockfile reflects large dependency additions including the full Expo/React Native ecosystem.
