+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+NoteFlow Client is a **Tauri + React desktop application** for intelligent meeting note-taking. It communicates with a Python gRPC backend for audio streaming, transcription, speaker diarization, and AI-powered summarization.
+
+The client consists of:
+- **React/TypeScript frontend** (`src/`) — UI components, hooks, contexts, and API layer
+- **Rust/Tauri backend** (`src-tauri/`) — Native IPC commands, gRPC client, audio capture/playback, encryption
+
+---
+
+## Development Commands
+
+```bash
+# Install dependencies
+npm install
+
+# Development (web only)
+npm run dev
+
+# Desktop development (requires Rust toolchain)
+npm run tauri:dev
+
+# Build
+npm run build
+npm run tauri:build
+```
+
+### Testing
+
+```bash
+# Unit tests (Vitest)
+npm run test              # Run once
+npm run test:watch        # Watch mode
+
+# Run specific test file
+npx vitest run src/hooks/use-audio-devices.test.ts
+
+# Rust tests
+npm run test:rs           # Equivalent: cd src-tauri && cargo test
+
+# E2E tests (Playwright)
+npm run test:e2e
+
+# Native E2E tests (WebdriverIO)
+npm run test:native
+
+# All tests
+npm run test:all
+```
+
+### Quality Checks
+
+```bash
+# TypeScript type checking
+npm run type-check
+
+# Linting (outputs to ../.hygeine/)
+npm run lint              # Biome + ESLint
+npm run lint:fix          # Auto-fix
+
+# Formatting
+npm run format            # Biome format
+npm run format:check      # Check only
+
+# Quality tests (code quality enforcement)
+npm run test:quality
+
+# Rust code quality
+npm run quality:rs
+```
+
+---
+
+## Architecture
+
+### TypeScript Layer
+
+```
+src/
+├── api/                  # Backend communication layer
+│   ├── interface.ts      # API interface definition (NoteFlowAdapter)
+│   ├── tauri-adapter.ts  # Production: Tauri IPC → Rust → gRPC
+│   ├── mock-adapter.ts   # Development: Simulated data
+│   ├── cached/           # Cached adapter implementations by domain
+│   └── types/            # API type definitions (core, enums, features)
+├── hooks/                # Custom React hooks
+├── contexts/             # React contexts (connection, workspace, project)
+├── components/           # React components (ui/ contains shadcn/ui)
+├── pages/                # Route pages
+└── lib/                  # Utilities and helpers
+    ├── config/           # Configuration (server, defaults)
+    ├── cache/            # Client-side caching
+    └── preferences.ts    # User preferences management
+```
+
+**Key Patterns:**
+- API abstraction via `NoteFlowAdapter` interface allows swapping implementations
+- `TauriAdapter` uses `invoke()` to call Rust commands which handle gRPC
+- React Query (`@tanstack/react-query`) for server state management
+- Contexts for global state: `ConnectionContext`, `WorkspaceContext`, `ProjectContext`
+
+### Rust Layer
+
+```
+src-tauri/src/
+├── commands/             # Tauri IPC command handlers
+│   ├── recording/        # Audio capture, device selection
+│   ├── playback/         # Audio playback control
+│   ├── triggers/         # Recording triggers (audio activity, calendar)
+│   └── *.rs              # Domain commands (meeting, summary, etc.)
+├── grpc/                 # gRPC client
+│   ├── client/           # Domain-specific gRPC clients
+│   ├── types/            # Rust type definitions
+│   ├── streaming/        # Audio streaming management
+│   └── noteflow.rs       # Generated protobuf types
+├── audio/                # Audio capture/playback
+├── crypto/               # AES-GCM encryption
+├── state/                # Runtime state management
+├── config.rs             # Configuration
+└── lib.rs                # Command registration
+```
+
+**Key Patterns:**
+- Commands are registered in `lib.rs` via `app_invoke_handler!` macro
+- State is managed through `AppState` with thread-safe `Arc` wrappers
+- gRPC calls use `tonic` client; streaming handled by `StreamManager`
+- Audio capture uses `cpal`, playback uses `rodio`
+
+### TypeScript ↔ Rust Bridge
+
+The `TauriAdapter` calls Rust commands via Tauri's `invoke()`:
+
+```typescript
+// TypeScript (src/api/tauri-adapter.ts)
+const result = await invoke<MeetingResult>('create_meeting', { request });
+
+// Rust (src-tauri/src/commands/meeting.rs)
+#[tauri::command]
+pub async fn create_meeting(
+    state: State<'_, AppState>,
+    request: CreateMeetingRequest,
+) -> Result<Meeting, String> { ... }
+```
+
+---
+
+## Code Reuse (CRITICAL)
+
+**BEFORE writing ANY new code, you MUST search for existing implementations.**
+
+This is not optional. Redundant code creates maintenance burden, inconsistency, and bugs.
+
+### Mandatory Search Process
+
+1. **Search existing modules first:**
+   - `src/lib/` — Utilities, helpers, formatters
+   - `src/hooks/` — React hooks (don't recreate existing hooks)
+   - `src/api/` — API utilities and types
+   - `src-tauri/src/commands/` — Rust command utilities
+   - `src-tauri/src/grpc/` — gRPC client utilities
+
+2. **Use symbolic search:**
+   ```bash
+   # Find existing functions by name pattern
+   grep -r "function_name" src/
+   cargo grep "fn function_name" src-tauri/
+   ```
+
+3. **Check imports in similar files** — they reveal available utilities
+
+4. **Only create new code if:**
+   - No existing implementation exists
+   - Existing code cannot be reasonably extended
+   - You have explicit approval for new abstractions
+
+### Anti-Patterns (FORBIDDEN)
+
+| Anti-Pattern | Correct Approach |
+|--------------|------------------|
+| New wrapper around existing function | Use existing function directly |
+| Duplicate utility in different module | Import from canonical location |
+| "Quick" helper that duplicates logic | Find and reuse existing helper |
+| New hook when existing hook suffices | Extend or compose existing hooks |
+
+### Examples
+
+**BAD:** Creating `query_capture_config()` when `resolve_input_device()` + `select_input_config()` already exist
+
+**GOOD:** Using existing functions directly:
+```rust
+use device::{resolve_input_device, select_input_config};
+let device = resolve_input_device(device_id)?;
+let config = select_input_config(&device, rate, channels)?;
+```
+
+**BAD:** Writing new formatting helpers in a component
+
+**GOOD:** Checking `src/lib/format.ts` first and adding there if truly needed
+
+---
+
+## Code Quality Standards
+
+### TypeScript
+
+**Linting:** Biome with strict rules
+- `noExplicitAny: error` — No `any` types
+- `noNonNullAssertion: error` — No `!` assertions
+- `noUnusedImports: error`, `noUnusedVariables: error`
+- `useConst: error`, `useImportType: error`
+
+**Type Safety:**
+- Strict TypeScript mode enabled
+- No `@ts-ignore` or `@ts-nocheck` comments
+- No `as any` or `as unknown` assertions
+
+### Rust
+
+**Clippy Configuration** (`src-tauri/clippy.toml`):
+- `cognitive-complexity-threshold: 25`
+- `too-many-lines-threshold: 100`
+- `too-many-arguments-threshold: 7`
+
+**Quality Script** (`npm run quality:rs`):
+- Magic number detection
+- Long function detection (>90 lines)
+- Deep nesting detection (>7 levels)
+- `unwrap()` usage detection
+- Module size limits (>500 lines flagged)
+
+### Logging (CRITICAL)
+
+**NEVER use `console.log`, `console.error`, `console.warn`, or `console.debug` directly.**
+
+Always use the `clientlog` system via `src/lib/debug.ts` or `src/lib/client-logs.ts`:
+
+```typescript
+// For debug logging (controlled by DEBUG flag)
+import { debug } from '@/lib/debug';
+const log = debug('MyComponent');
+log('Something happened', { detail: 'value' });
+
+// For error logging (always outputs)
+import { errorLog } from '@/lib/debug';
+const logError = errorLog('MyComponent');
+logError('Something failed', error);
+
+// For direct clientlog access
+import { addClientLog } from '@/lib/client-logs';
+addClientLog({
+  level: 'info',
+  source: 'app',
+  message: 'Event occurred',
+  details: 'Additional context',
+});
+```
+
+**Why:**
+- `clientlog` persists logs to localStorage for later viewing in Analytics
+- Logs are structured with level, source, timestamp, and metadata
+- Debug logs can be toggled at runtime via `DEBUG=true` in localStorage
+- Console logging is ephemeral and not accessible to users
+
+**Log Levels:** `debug` | `info` | `warning` | `error`
+
+**Log Sources:** `app` | `api` | `sync` | `auth` | `system`
+
+### Test Quality Enforcement
+
+The `src/test/code-quality.test.ts` suite enforces:
+- No repeated string literals across files
+- No duplicate utility implementations
+- No TODO/FIXME comments
+- No commented-out code
+- No magic numbers
+- No hardcoded colors or API endpoints
+- No `any` types or type assertions
+- File size limits (500 lines max, with exceptions)
+- Centralized helpers (format/parse/convert utilities)
+
+---
+
+## Key Integration Points
+
+### Adding a New Tauri Command
+
+1. **Rust**: Add command in `src-tauri/src/commands/*.rs`
+2. **Rust**: Register in `src-tauri/src/lib.rs` → `app_invoke_handler!`
+3. **TypeScript**: Add to `src/api/tauri-adapter.ts`
+4. **TypeScript**: Add to `src/api/interface.ts` (if new method)
+5. **TypeScript**: Add types to `src/api/types/`
+
+### Adding a New API Method
+
+1. Update `interface.ts` with method signature
+2. Implement in `tauri-adapter.ts` (production)
+3. Implement in `mock-adapter.ts` (development/testing)
+4. Add cached version in `cached/*.ts` if caching needed
+
+### gRPC Schema Changes
+
+When the backend proto changes:
+1. Rebuild Tauri: `npm run tauri:build` (triggers `build.rs` to regenerate `noteflow.rs`)
+2. Update Rust types in `src-tauri/src/grpc/types/`
+3. Update TypeScript types in `src/api/types/`
+4. Update adapters as needed
+
+---
+
+## Testing Patterns
+
+- Tests use Vitest with jsdom environment
+- `@testing-library/react` for component testing
+- Tauri plugins are mocked in `src/test/mocks/`
+- `src/test/setup.ts` configures jest-dom matchers
+
+```bash
+# Run single test file
+npx vitest run src/hooks/use-audio-devices.test.ts
+
+# Run tests matching pattern
+npx vitest run -t "should handle"
+
+# Run with coverage
+npx vitest run --coverage
+```
+
+---
+
+## Configuration Files
+
+| File | Purpose |
+|------|---------|
+| `biome.json` | Linting and formatting rules |
+| `tsconfig.json` | TypeScript configuration |
+| `vitest.config.ts` | Test runner configuration |
+| `src-tauri/Cargo.toml` | Rust dependencies |
+| `src-tauri/clippy.toml` | Rust linting thresholds |
+| `src-tauri/tauri.conf.json` | Tauri app configuration |

+# Native E2E Testing with WebdriverIO
+
+This directory contains end-to-end tests that run against the actual Tauri desktop application using WebdriverIO and tauri-driver.
+
+## Prerequisites
+
+### 1. Install tauri-driver
+
+```bash
+cargo install tauri-driver
+```
+
+This installs the WebDriver server that bridges WebdriverIO to Tauri's WebView.
+
+> Note: tauri-driver does not support macOS. Use the Appium mac2 harness described below.
+
+### 2. (Windows only) Install msedgedriver
+
+Tauri on Windows uses WebView2 (Edge-based), which requires Microsoft Edge WebDriver:
+
+1. Check your Edge version: `edge://version`
+2. Download matching driver from: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/
+3. Extract `msedgedriver.exe` and either:
+   - Add its location to your PATH
+   - Set `MSEDGEDRIVER_PATH` environment variable
+   - Place it in your home directory (`C:\Users\YourName\`)
+
+### 3. Install npm dependencies
+
+```bash
+cd client
+npm install
+```
+
+### 4. Build the Tauri app
+
+```bash
+npm run tauri:build
+```
+
+The tests require a built binary. Debug builds also work:
+
+```bash
+cd src-tauri && cargo build
+```
+
+## Running Tests
+
+### Run all native tests
+
+```bash
+npm run test:native
+```
+
+### Build and test in one command
+
+```bash
+npm run test:native:build
+```
+
+## macOS Native Testing (Appium mac2)
+
+Tauri does not ship a macOS WebDriver server, so native macOS tests use Appium.
+
+### Prerequisites (macOS)
+
+1. Install Appium 2:
+
+```bash
+npm install -g appium
+```
+
+2. Install the mac2 driver:
+
+```bash
+appium driver install mac2
+```
+
+3. Install Xcode and Command Line Tools, then accept the license:
+
+```bash
+sudo xcodebuild -license accept
+```
+
+If needed, point CLI tools to Xcode:
+
+```bash
+sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
+```
+
+4. Enable Developer Mode (System Settings → Privacy & Security → Developer Mode).
+
+You can also enable dev tools access via CLI:
+
+```bash
+sudo /usr/sbin/DevToolsSecurity -enable
+sudo dseditgroup -o edit -a "$(whoami)" -t user _developer
+```
+
+Log out and back in after enabling Developer Mode.
+
+5. Enable Automation Mode (required by XCTest UI automation):
+
+```bash
+sudo automationmodetool enable-automationmode-without-authentication
+```
+
+Approve the system prompt when it appears.
+
+6. Grant Accessibility permissions:
+
+- Terminal (or your shell app)
+- Xcode Helper (`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Xcode/Agents/Xcode Helper.app`)
+
+7. Build the Tauri app bundle:
+
+```bash
+npm run tauri:build
+```
+
+8. Start Appium:
+
+```bash
+appium --base-path / --log-level error
+```
+
+### Run macOS native tests
+
+```bash
+npm run test:native:mac
+```
+
+## Test Structure
+
+```
+e2e-native/
+├── fixtures.ts       # Test helpers and utilities
+├── app.spec.ts       # Core app tests
+├── screenshots/      # Failure screenshots
+└── README.md         # This file
+```
+
+## Writing Tests
+
+Tests use WebdriverIO's Mocha framework:
+
+```typescript
+import { waitForAppReady, navigateTo, invokeCommand } from './fixtures';
+
+describe('Feature', () => {
+  before(async () => {
+    await waitForAppReady();
+  });
+
+  it('should do something', async () => {
+    await navigateTo('/settings');
+
+    // Direct Tauri IPC
+    const result = await invokeCommand('get_preferences');
+    expect(result).toBeDefined();
+  });
+});
+```

+| `waitForAppReady()` | Wait for React app to mount |
+| `navigateTo(path)` | Navigate to a route |
+| `isTauriAvailable()` | Check if Tauri IPC works |
+| `invokeCommand(cmd, args)` | Call Tauri command directly |
+| `waitForLoadingComplete()` | Wait for spinners to clear |
+| `clickButton(text)` | Click button by text |
+| `fillInput(selector, value)` | Fill an input field |
+| `waitForToast(pattern)` | Wait for toast notification |
+| `takeScreenshot(name)` | Save screenshot |
+
+## Comparison: Playwright vs WebdriverIO Native
+
+| Aspect | Playwright (e2e/) | WebdriverIO (e2e-native/) |
+|--------|-------------------|---------------------------|
+| Target | Web dev server | Built Tauri app |
+| IPC | Mock adapter | Real Rust commands |
+| Audio | Not available | Real device access |
+| Speed | Fast | Slower (app launch) |
+| CI | Easy | Needs Windows runner |
+
+## Troubleshooting
+
+### "Tauri binary not found"
+
+Build the app first:
+
+```bash
+npm run tauri:build
+```
+
+### "Connection refused" on port 4444
+
+Ensure tauri-driver is installed and no other WebDriver is running on port 4444.
+
+### "EPERM" or "Operation not permitted" on localhost ports
+
+Grant Local Network access to your terminal (or the app running tests) in
+System Settings → Privacy & Security → Local Network. Also check that no firewall
+or network filter blocks `127.0.0.1:4723`.
+
+### Tests hang on Windows
+
+Check Windows Firewall isn't blocking tauri-driver.exe.
+
+### WebView2 not found
+
+Install Microsoft Edge WebView2 Runtime from: https://developer.microsoft.com/en-us/microsoft-edge/webview2/
