+# Authentication System Documentation
+
+## Overview
+
+Black Canyon Tickets uses a unified authentication system built on top of Supabase Auth with server-side rendering (SSR) support. All authentication functionality is centralized in a single module (`src/lib/auth-unified.ts`) to ensure consistency and maintainability.
+
+## Architecture
+
+### Core Module: `auth-unified.ts`
+
+The unified auth module is the single source of truth for all authentication in the application. It provides:
+
+- 🔐 **Session-based authentication** using Supabase cookies
+- 🎭 **Role-based access control** (User, Admin, Super Admin)
+- 🏢 **Organization-based access control**
+- 🛡️ **Security logging and rate limiting**
+- 📝 **Type-safe authentication context**
+- 🐳 **Docker-friendly cookie handling**
+
+### Key Features
+
+1. **Universal Compatibility**: Works with both `Request` objects (API routes) and `AstroCookies` (Astro pages)
+2. **SSR Support**: Full server-side rendering support with proper cookie handling
+3. **Bearer Token Fallback**: Supports Authorization header for API clients
+4. **Security Hardening**: Built-in CSRF protection, rate limiting, and security logging
+5. **Type Safety**: Full TypeScript support with proper types
+
+## Usage Guide
+
+### Basic Authentication Check
+
+```typescript
+// In Astro pages (.astro files)
+import { verifyAuth } from '../lib/auth-unified';
+
+// Check if user is authenticated (returns null if not)
+const auth = await verifyAuth(Astro.cookies);
+
+// In API routes (.ts files)
+const auth = await verifyAuth(request);
+```
+
+### Requiring Authentication
+
+```typescript
+// Throws AuthError if not authenticated
+const auth = await requireAuth(Astro.cookies);
+
+// The auth object contains:
+// - user: Supabase user object
+// - session: Session information
+// - isAdmin: boolean
+// - isSuperAdmin: boolean
+// - organizationId: string | null
+```
+
+### Role-Based Access Control
+
+```typescript
+// Require admin access
+const auth = await requireAdmin(Astro.cookies);
+
+// Require super admin access
+const auth = await requireSuperAdmin(Astro.cookies);
+
+// Check organization access
+const auth = await requireOrganizationAccess(Astro.cookies, organizationId);
+```
+
+### Protected Page Pattern
+
+```typescript
+---
+import Layout from '../layouts/Layout.astro';
+import { verifyAuth } from '../lib/auth-unified';
+
+export const prerender = false; // Enable SSR
+
+const auth = await verifyAuth(Astro.cookies);
+if (!auth) {
+  return Astro.redirect('/login');
+}
+---
+
+<Layout title="Protected Page">
+  <h1>Welcome, {auth.user.email}!</h1>
+</Layout>
+```
+
+### Protected API Route Pattern
+
+```typescript
+import type { APIRoute } from 'astro';
+import { requireAuth, createAuthResponse } from '../lib/auth-unified';
+
+export const GET: APIRoute = async ({ request }) => {
+  try {
+    const auth = await requireAuth(request);
+    
+    // Your protected logic here
+    const data = { userId: auth.user.id };
+    
+    return createAuthResponse(data);
+  } catch (error) {
+    return createAuthResponse(
+      { error: error.message },
+      error.statusCode || 401
+    );
+  }
+};
+```
+
+### Using the Middleware Pattern
+
+```typescript
+import { withAuth } from '../lib/auth-unified';
+
+// Wrap your handler with authentication
+export const GET: APIRoute = async ({ request }) => {
+  return withAuth(request, async (auth) => {
+    // This code only runs if authenticated
+    return new Response(JSON.stringify({
+      message: `Hello ${auth.user.email}`
+    }));
+  });
+};
+```
+
+## Authentication Flow
+
+1. **Login**: User submits credentials → `/api/auth/login` → Supabase sets cookies → Redirect to dashboard
+2. **Session Check**: Every request → `verifyAuth()` checks cookies → Returns auth context or null
+3. **Protected Routes**: Page/API checks auth → Redirects to login or returns 401 if not authenticated
+4. **Logout**: Clear session → `/api/auth/logout` → Supabase clears cookies → Redirect to login
+
+## Error Handling
+
+The auth system uses a custom `AuthError` class with specific error codes:
+
+```typescript
+try {
+  const auth = await requireAuth(request);
+} catch (error) {
+  if (error instanceof AuthError) {
+    switch (error.code) {
+      case 'NO_SESSION':
+        // User not logged in
+        break;
+      case 'NO_PERMISSION':
+        // User lacks required role
+        break;
+      case 'EXPIRED':
+        // Session expired
+        break;
+    }
+  }
+}
+```
+
+## Security Features
+
+### CSRF Protection
+
+```typescript
+// Generate token for forms
+const csrfToken = generateCSRFToken();
+
+// Verify token on submission
+if (!verifyCSRFToken(request, sessionToken)) {
+  throw new Error('Invalid CSRF token');
+}
+```
+
+### Rate Limiting
+
+```typescript
+// Check rate limit (10 requests per minute by default)
+const identifier = `login:${email}`;
+if (!checkRateLimit(identifier, 5, 60000)) {
+  throw new Error('Too many attempts');
+}
+```
+
+### Security Logging
+
+All authentication events are automatically logged:
+- Failed login attempts
+- Successful authentications
+- Permission denied events
+- Rate limit violations
+
+## Testing
+
+Visit `/auth-test-unified` to test the authentication system. This page shows:
+- Current authentication status
+- Session information
+- Request headers and cookies
+- Links to test protected routes
+
+## Migration Guide
+
+### From Old Auth System
+
+1. **Update imports**:
+   ```typescript
+   // Old
+   import { verifyAuth } from '../lib/auth';
+   
+   // New (but old path still works via proxy)
+   import { verifyAuth } from '../lib/auth-unified';
+   ```
+
+2. **Use Astro.cookies instead of Astro.request**:
+   ```typescript
+   // Old
+   const auth = await verifyAuth(Astro.request);
+   
+   // New (better SSR support)
+   const auth = await verifyAuth(Astro.cookies);
+   ```
+
+3. **Handle new error types**:
+   ```typescript
+   // Old
+   if (!auth) throw new Error('Not authenticated');
+   
+   // New
+   import { AuthError } from '../lib/auth-unified';
+   if (!auth) throw new AuthError('Not authenticated', 'NO_SESSION');
+   ```
+
+## Docker Considerations
+
+The unified auth system is designed to work seamlessly in Docker environments:
+
+1. **Cookie Domain**: Automatically handles cookie domain settings
+2. **Secure Cookies**: Uses secure cookies in production
+3. **Proxy Support**: Correctly reads IP addresses behind proxies
+
+## Environment Variables
+
+```bash
+# Required for auth to work
+PUBLIC_SUPABASE_URL=https://your-project.supabase.co
+PUBLIC_SUPABASE_ANON_KEY=your-anon-key
+SUPABASE_SERVICE_ROLE_KEY=your-service-key
+
+# Optional for enhanced security
+COOKIE_DOMAIN=.yourdomain.com  # For subdomain support
+NODE_ENV=production            # Enables secure cookies
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **"No session found" after login**
+   - Check cookie settings in browser
+   - Verify Supabase URL and keys are correct
+   - Ensure cookies are not blocked
+
+2. **Dashboard flashing before redirect**
+   - Ensure using `Astro.cookies` not `Astro.request`
+   - Verify `prerender = false` is set
+   - Check server-side auth is enabled
+
+3. **Auth works locally but not in Docker**
+   - Check `COOKIE_DOMAIN` environment variable
+   - Verify proxy headers are being forwarded
+   - Ensure secure cookie settings match environment
+
+### Debug Mode
+
+Enable debug logging in development:
+
+```typescript
+// In your page or API route
+import { authDebug } from '../lib/auth-unified';
+
+authDebug.logCookies(request);
+authDebug.logSession(session);
+```
+
+## Best Practices
+
+1. **Always use the unified auth module** - Don't create separate auth implementations
+2. **Use `Astro.cookies` for pages** - Better SSR support than `Astro.request`
+3. **Handle errors gracefully** - Show user-friendly messages, not technical errors
+4. **Test auth flows regularly** - Use `/auth-test-unified` to verify functionality
+5. **Keep sessions secure** - Use HTTPS in production, set proper cookie flags
+
+## Future Enhancements
+
+- [ ] Refresh token rotation
+- [ ] Remember me functionality
+- [ ] Two-factor authentication
+- [ ] Session activity tracking
+- [ ] IP-based session validation
