+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Chad is a voice/video chat desktop app built with **Tauri 2 + Nuxt 4 (SPA) + mediasoup-client**. It uses an SFU (Selective Forwarding Unit) architecture for WebRTC media — each peer sends to the server, which forwards selectively to others.
+
+## Commands
+
+| Command | Description |
+|---------|-------------|
+| `yarn dev` | Start dev server (binds to all interfaces via `--host`) |
+| `yarn generate` | Generate static site to `.output/public` |
+| `yarn build` | Build for production |
+| `yarn preview` | Preview production build |
+| `npx eslint .` | Lint the project |
+| `npx eslint --fix .` | Lint and auto-fix |
+
+**Tauri desktop build**: `yarn tauri build` (runs `yarn generate` first automatically).
+
+Package manager is **Yarn 4.12.0**. No test framework is configured.
+
+## Architecture
+
+### Composable-Based State (No Pinia/Vuex)
+
+All state is managed through Vue composables using `@vueuse/core`'s `createGlobalState` and `createSharedComposable`. Nuxt auto-imports all composables from `app/composables/`.
+
+**Dependency graph** (arrows = "depends on"):
+
+```
+useAuth (foundation — user session)
+  └→ useSignaling (Socket.IO connection to /webrtc namespace)
+       └→ useClients (connected peer list)
+            └→ useMediasoup (transports, producers, consumers)
+                 ├← usePreferences (device IDs, audio effects, hotkeys)
+                 │    └← useDevices (enumerates hardware via getUserMedia)
+                 └← useSfx (Howler.js sound effects)
+
+useApp (top-level orchestrator — mute/unmute, video/share toggles)
+  └→ depends on useClients, useMediasoup, useSignaling, useSfx
+```
+
+### Composable Tiers
+
+**Global state** (`createGlobalState` — single instance, persists for app lifetime):
+- `useApp` — ready state, input/output mute, video/share toggles, version info
+- `useAuth` — `me` ref, login/register/logout
+- `useClients` — `clients[]` array, add/remove/update peers
+- `usePreferences` — device selections, audio effects, hotkeys (localStorage + server sync)
+- `useUpdater` — Tauri app update checks
+- `useFullscreenVideo` — fullscreen video element control
+
+**Shared** (`createSharedComposable` — single instance, disposed when last consumer unmounts):
+- `useMediasoup` — mediasoup Device, transports, producers, consumers, speaking state
+- `useSignaling` — Socket.IO client, connect/disconnect
+- `useSfx` — sound effect playback via Howler.js
+
+**Per-instance** (new instance per call):
+- `useClient(socketId)` — per-peer volume/mute (localStorage), filtered consumers/producers
+- `useAudioContext(audioTrack)` — Web Audio API gain node for per-client volume
+- `useDevices` — media device enumeration
+
+### Initialization Flow
+
+1. **Middleware** (global, ordered by filename prefix):
+   - `00.updater` — Tauri update check, redirects to `/updater` if available
+   - `01.auth` — validates session via `GET /me`, redirects guests to `/login`
+   - `02.user-preferences` — loads server-synced preferences for authenticated users
+2. **Plugins**: build info logging, Tauri hotkey registration
+3. **Layout** (`default.vue`): calls `useApp()` which triggers `useSignaling().connect()`
+4. **Socket authenticated** → mediasoup Device created → transports created → `join()` → mic enabled
+
+### mediasoup Integration
+
+**Producer types** (tracked in `appData.source`):
+- Microphone: `kind='audio'`, `source='mic-video'`
+- Camera: `kind='video'`, `source='mic-video'`
+- Screen share: `kind='video'`, `source='share'`
+
+**Consumer filtering** uses `kind` + `appData.source` to distinguish audio/video/share streams.
+
+Transports use `emitWithAck()` on the Socket.IO connection for all signaling (create, connect, produce, join, pause/resume/close).
+
+### API & Networking
+
+- **REST API**: `shared/chad-api.ts` — `$fetch` instance with `credentials: 'include'`, base URL from `__API_BASE_URL__` build-time define
+- **WebSocket**: Socket.IO to `/webrtc` namespace for signaling
+- **Vite proxy**: `/api` → production API server (for dev)
+
+### Shared Types
+
+`shared/types.ts` defines `ChadClient`, `Consumer`, `Producer`, `AppData`, `UpdatedClient` — used by both composables and components.
+
+## Code Conventions
+
+- **ESLint**: `@antfu/eslint-config` with formatters enabled
+- **Vue SFC block order**: `<template>`, `<script>`, `<style>` (enforced by ESLint)
+- **`console.log` allowed** (no-console is off)
+- **PrimeVue components** are prefixed: `PrimeButton`, `PrimeCard`, etc.
+- **Icons**: `lucide-vue-next` + `primeicons`
+- **Styling**: Tailwind CSS 4 + PrimeVue Aura theme (Zinc palette, dark-first)
+- **Reactivity**: mediasoup objects wrapped with `markRaw()` to prevent deep reactivity; `triggerRef()` used for manual reactivity triggers on the clients array
+
+## Build-Time Defines
+
+Set via `.env` or environment variables:
+- `API_BASE_URL` — backend API base (default: `http://localhost:4000/chad`)
+- `COMMIT_SHA` — git commit hash (default: `'local'`)
+
+## Tauri
+
+- App identifier: `xyz.koptilnya.chad`
+- Windows-only NSIS installer (`bundle.targets: ["nsis"]`)
+- Plugins: global-shortcut, process, updater, single-instance, log
+- Frontend dist: `.output/public` (from `yarn generate`)
+- `@tauri-apps/plugin-*` packages provide JS bindings; use `window.__TAURI__` check or the `useTauri()` composable for Tauri detection
