Explore the convx project at /Users/pascal/Code/business/convx to understand:
1. How the web interface is structured (look at src/convx_ai/web/, web/, src/convx_ai/server.py)
2. How it's currently packaged (pyproject.toml, any build config)
3. How static assets are being served or bundled
4. Any existing tests for the web interface

Look at the key files and return a comprehensive summary of what you find.

## Comprehensive Web Interface Summary for convx

### 1. Web Interface Architecture

The convx project has a **React + TypeScript frontend** that integrates with a **Python HTTP server backend**:

#### Frontend Location
- **Source code**: `/Users/pascal/Code/business/convx/web/` (development)
- **Built assets**: `/Users/pascal/Code/business/convx/src/convx_ai/web/` (production)
- **Structure**:
  - `web/src/main.tsx` - React entry point
  - `web/src/App.tsx` - Main app component (tabbed interface with Explore/Stats tabs)
  - `web/src/components/` - Reusable UI components:
    - `explore/` - Session browsing components (SessionList, SessionPreview, SessionFilters, SessionCommandPalette)
    - `stats/` - Analytics visualization components (StackedChart, ExpandedChart, StackedSourceChart)
    - `ui/` - Base UI primitives (tabs, badge, input, scroll-area)
  - `web/src/lib/api.ts` - API client for backend communication

#### Backend Server
- **File**: `/Users/pascal/Code/business/convx/src/convx_ai/server.py` (225 lines)
- **Class**: `ConvxHandler` (extends `BaseHTTPRequestHandler`)
- **Purpose**: Minimal stdlib HTTP server using Python's `http.server` module
- **Features**:
  - Serves static files from `convx_ai.web` package via `importlib.resources`
  - SPA fallback: unknown routes serve `index.html`
  - Exposes REST API endpoints:
    - `/api/sessions` - List all sessions
    - `/api/sessions/{key}/content` - Get markdown content
    - `/api/sessions/{key}/json` - Get raw JSON session data
    - `/api/search?q=query` - Full-text search
    - `/api/stats` - Retrieve statistics data
  - CORS headers enabled for all responses
  - Single-threaded `ThreadingHTTPServer` with daemon threads
  - Automatic port discovery via `find_free_port()`

#### CLI Integration
- **File**: `/Users/pascal/Code/business/convx/src/convx_ai/cli.py`
- **Command**: `explore` command (lines 255-305)
- **Features**:
  - `--output-path` - Directory containing exported conversations
  - `--api-only` - Start API without static files (for dev with Vite)
  - `--port` - Custom port (0 = auto-select)
  - Default port 7331 in API-only mode
  - Auto-opens browser with `webbrowser.open()`
  - Runs server in daemon thread

### 2. Build Configuration

#### Vite Configuration
- **File**: `/Users/pascal/Code/business/convx/web/vite.config.ts`
- **Key settings**:
  - Output directory: `../src/convx_ai/web` (builds directly into Python package)
  - Empty output directory on build
  - Proxy configuration for dev mode (`/api` → `http://localhost:${CONVX_API_PORT}` or default 7331)
  - React plugin enabled
  - Path alias: `@` → `./src`

#### Build Steps
```bash
npm run build   # Runs: tsc -b && vite build
npm run dev     # Starts Vite dev server with proxy
npm run preview # Preview production build
```

#### Package.json Dependencies
- **React ecosystem**: React 18.3.1, React DOM, React Markdown
- **UI libraries**: Radix UI (dialog, dropdown, label, popover, scroll-area, separator, slot, tabs, tooltip)
- **Styling**: Tailwind CSS 3.4.17, Autoprefixer
- **Charting**: Recharts 2.15.0 (for stats visualizations)
- **Icons**: Lucide React 0.474.0
- **Utilities**: clsx, class-variance-authority, tailwind-merge, cmdk (command palette)
- **TypeScript**: 5.7.3

#### Styling Setup
- **Tailwind config**: Full customization with CSS variables for theming
- **PostCSS**: Configured with Tailwind + Autoprefixer
- **CSS variables**: Define dark mode, colors, borders, radius
- **Typography plugin**: For markdown rendering (`@tailwindcss/typography`)
- **Tailwind globals**: Applied via `index.css` with `@tailwind` directives

### 3. Static Assets and Packaging

#### Built Assets Structure
```
src/convx_ai/web/
├── index.html                           # Entry point (452 bytes)
└── assets/
    ├── index-CEqwe3J-.js               # Bundled JS (229 lines)
    └── index-DFUd2Md4.css              # Bundled CSS (1 line - minified)
```

#### Asset Serving
- **Method**: `importlib.resources` (Python 3.9+)
- **Location**: Assets are included in the installed package
- **Fallback**: If static file not found, serves `index.html` (SPA routing)
- **MIME type detection**: Uses Python's `mimetypes` module
- **No build configuration in pyproject.toml**: Relies on default hatchling behavior to include all files under `src/convx_ai/`

#### Static File Server Implementation
- Assets loaded at runtime via `files("convx_ai.web")` in `_handle_static()`
- Supports safe path traversal (filters `.` and `..` segments)
- Returns appropriate content types
- Handles missing files with 404 or SPA fallback

### 4. Frontend Features

#### App Component (`App.tsx`)
- **Tabbed interface**: "Explore" and "Stats" tabs
- **Explore tab**: Two-column layout
  - Left: Session list with search/filtering
  - Right: Session preview with markdown rendering
- **Stats tab**: Three visualizations
  - Volume by source (stacked area chart)
  - Word volume by project (stacked area chart)
  - Project share over time (percentage chart)
- **Keyboard shortcuts**:
  - `Cmd/Ctrl + K` - Open command palette
  - `/` - Focus search box

#### Components
- **SessionList** - Filterable session browser with source badges (Claude=orange, Codex=green, Cursor=blue)
- **SessionPreview** - Markdown renderer with JSON metadata fallback
- **SessionCommandPalette** - Quick search/navigation
- **SessionFilters** - Filter by source, date range, project
- **Chart components** - Recharts-based visualizations with date/project series data

#### API Client (`lib/api.ts`)
- Typed interfaces: `Session`, `SessionMessage`, `SessionData`, `StatsData`
- Endpoints use relative base URL (`""`) for same-origin requests
- Error handling with descriptive messages
- Detects when API returns HTML instead of JSON (helpful error message)

### 5. Testing

#### Current Test Coverage
- `/Users/pascal/Code/business/convx/tests/test_stats.py` (331 lines) - Comprehensive stats module tests
- Tests for: word counting, date parsing, project extraction, series computation
- No web interface-specific tests found (no test file for `server.py` or frontend)

#### Test Configuration
- **pytest**: Located in `pyproject.toml`
- **Test paths**: `tests/`
- **Python path**: `src/`

### 6. Development Workflow

#### Development Mode
```bash
cd web
npm run dev              # Starts Vite on port 5173 with API proxy
# In another terminal:
cd ..
uv run convx explore --api-only --port 7331
```

#### Production Mode
```bash
cd web
npm run build           # Builds to src/convx_ai/web/
cd ..
uv run convx explore    # Serves static files from package
```

#### Key Distinction
- **Development**: Vite dev server + proxied API backend
- **Production**: Embedded static assets served by Python HTTP server

### 7. Integration Points

#### Session Data Flow
1. **Backend searches/indexes** sessions (using `search.py`, `stats.py`)
2. **API endpoint** returns session metadata or content
3. **Frontend fetches** via `lib/api.ts`
4. **React components** render using Tailwind CSS
5. **Markdown content** rendered via `react-markdown`

#### Configuration
- **API port discovery**: Automatic in production, configurable via `--port`
- **Vite proxy**: Uses `CONVX_API_PORT` env var (defaults to 7331)
- **Index requirement**: Requires `.convx/index.json` to exist before serving

### Summary of Key Findings

This is a modern **full-stack web application** with:
- **Frontend**: React 18 + TypeScript + Tailwind CSS + Recharts
- **Backend**: Python stdlib HTTP server (no frameworks like Flask/FastAPI)
- **Build**: Vite with single-step asset bundling into Python package
- **Packaging**: Assets embedded via `importlib.resources`, no separate manifest needed
- **Architecture**: SPA with REST API backend, auto-discovery of ports, no external dependencies for serving
- **No existing web tests**: The project has stats/integration tests but lacks dedicated web server or frontend tests
