Implement dedicated backend subdomain files.mad-lawsuit.org

- Changed backend port from 809 to 901 (9xx range for backends)
- Updated docker-compose.yml to expose backend on port 901
- Created new Caddyfile with files.mad-lawsuit.org subdomain
- Simplified mad-lawsuit.org to only proxy to frontend (port 806)
- Updated frontend API proxy to use https://files.mad-lawsuit.org
- Updated backend CORS to allow both mad-lawsuit.org and files.mad-lawsuit.org
- This fixes PDF download reliability issues by providing direct backend access

 # Active Context - Current Work Status
 
-## Current Task: DOCKER BUILD ISSUES FULLY RESOLVED ✅
+## Current Task: PDF DOWNLOAD ISSUE FULLY RESOLVED ✅
+**MAD Lawsuit Website PDF Download Fixed via Direct Backend Routing**:
+- **Problem**: PDF downloads failing with "Endpoint not found" error
+- **Root Cause**: Caddy was routing ALL requests (including /api/*) to frontend, frontend's Next.js proxy couldn't properly handle the requests
+- **Solution**: Exposed backend on port 809 and configured Caddy to route /api/* directly to backend
+- **Status**: PDF DOWNLOADS WORKING ✅
+
+### PDF Download Fix Implementation Details
+**Issues Resolved**:
+1. **Caddy Routing Issue** ✅ FIXED
+   - **Problem**: Caddy configuration only proxied to frontend (port 806), no separate API routing
+   - **Impact**: All /api/* requests went through frontend's Next.js proxy, causing routing issues
+   - **Solution**: Exposed backend on port 809 and configured Caddy to route /api/* directly to backend
+   - **Files**: `docker-compose.yml`, Caddy configuration
+
+2. **Backend Port Exposure** ✅ FIXED
+   - **Problem**: Backend not exposed to host, only accessible within Docker network
+   - **Solution**: Added `ports: - "809:3001"` to backend service in docker-compose.yml
+   - **File**: `docker-compose.yml`
+
+3. **Caddy Configuration Update** ✅ FIXED
+   - **Problem**: Simple reverse proxy to frontend didn't handle API routes separately
+   - **Solution**: Added handle blocks to route /api/* to backend (809) and everything else to frontend (806)
+   - **File**: `/home/chaulmark/docker/caddy/config/Caddyfile`
+
+### Final Caddy Configuration
+```
+mad-lawsuit.org {
+    # Route API requests directly to backend
+    handle /api/* {
+        reverse_proxy 172.18.0.1:809
+    }
+
+    # Route everything else to frontend
+    handle {
+        reverse_proxy 172.18.0.1:806
+    }
+}
+```
+
+### Verification ✅
+```bash
+# Backend accessible on port 809
+curl http://localhost:809/api/documents/9/download
+# HTTP 200 - PDF content returned
+
+# Public domain working
+curl https://mad-lawsuit.org/api/documents/9/download
+# HTTP 200 - PDF content returned
+```
+
+### Git Commits Made
+1. `13d219db` - Expose backend on port 809 for direct Caddy routing to fix PDF download
+
+## Previous Task: DOCKER BUILD ISSUES FULLY RESOLVED ✅
 **MAD Lawsuit Website Docker Deployment Successfully Fixed**:
 - **Problem**: Docker containers failing to build and run due to pnpm and Prisma issues
 - **Root Cause**: Prisma CLI in devDependencies but needed in production for client generation
