fix(dim_school): use case-insensitive comparison for phase inference

GIAS provides 'Not Applicable' (capital A) but the check used 'Not applicable',
so the case-sensitive != matched true and skipped the age-range inference.

+# Docker Deployment Guide
+
+## Quick Start
+
+Deploy the complete SchoolCompare stack (PostgreSQL + FastAPI + Next.js) with one command:
+
+```bash
+docker-compose up -d
+```
+
+This will start:
+- **PostgreSQL** on port 5432 (database)
+- **FastAPI** on port 8000 (backend API)
+- **Next.js** on port 3000 (frontend)
+
+## Service Details
+
+### PostgreSQL Database
+- **Port**: 5432
+- **Container**: `schoolcompare_db`
+- **Credentials**:
+  - User: `schoolcompare`
+  - Password: `schoolcompare`
+  - Database: `schoolcompare`
+- **Volume**: `postgres_data` (persistent storage)
+
+### FastAPI Backend
+- **Port**: 8000 → 80 (container)
+- **Container**: `schoolcompare_backend`
+- **Built from**: Root `Dockerfile`
+- **API Endpoint**: http://localhost:8000/api
+- **Health Check**: http://localhost:8000/api/data-info
+
+### Next.js Frontend
+- **Port**: 3000
+- **Container**: `schoolcompare_nextjs`
+- **Built from**: `nextjs-app/Dockerfile`
+- **URL**: http://localhost:3000
+- **Connects to**: Backend via internal network
+
+## Commands
+
+### Start all services
+```bash
+docker-compose up -d
+```
+
+### View logs
+```bash
+# All services
+docker-compose logs -f
+
+# Specific service
+docker-compose logs -f nextjs
+docker-compose logs -f backend
+docker-compose logs -f db
+```
+
+### Check status
+```bash
+docker-compose ps
+```
+
+### Stop all services
+```bash
+docker-compose down
+```
+
+### Rebuild after code changes
+```bash
+# Rebuild and restart specific service
+docker-compose up -d --build nextjs
+
+# Rebuild all services
+docker-compose up -d --build
+```
+
+### Clean restart (remove volumes)
+```bash
+docker-compose down -v
+docker-compose up -d
+```
+
+## Initial Database Setup
+
+After first start, you may need to initialize the database:
+
+```bash
+# Enter the backend container
+docker exec -it schoolcompare_backend bash
+
+# Run migrations or data loading
+python -m backend.data_loader
+```
+
+## Accessing Services
+
+Once running:
+- **Frontend**: http://localhost:3000
+- **Backend API**: http://localhost:8000/api
+- **API Docs**: http://localhost:8000/docs (Swagger UI)
+- **Database**: localhost:5432 (use any PostgreSQL client)
+
+## Environment Variables
+
+Create a `.env` file in the root directory to customize:
+
+```env
+# Database
+POSTGRES_USER=schoolcompare
+POSTGRES_PASSWORD=your_secure_password
+POSTGRES_DB=schoolcompare
+
+# Backend
+DATABASE_URL=postgresql://schoolcompare:your_secure_password@db:5432/schoolcompare
+
+# Frontend (for client-side access)
+NEXT_PUBLIC_API_URL=http://localhost:8000/api
+```
+
+Then run:
+```bash
+docker-compose up -d
+```
+
+## Troubleshooting
+
+### Backend not connecting to database
+```bash
+# Check database health
+docker-compose ps
+
+# View backend logs
+docker-compose logs backend
+
+# Restart backend
+docker-compose restart backend
+```
+
+### Frontend not connecting to backend
+```bash
+# Check backend health
+curl http://localhost:8000/api/data-info
+
+# Check Next.js environment variables
+docker exec schoolcompare_nextjs env | grep API
+```
+
+### Port already in use
+```bash
+# Change ports in docker-compose.yml
+# For example, change "3000:3000" to "3001:3000"
+```
+
+### Rebuild from scratch
+```bash
+docker-compose down -v
+docker system prune -a
+docker-compose up -d --build
+```
+
+## Production Deployment
+
+For production, update the following:
+
+1. **Use secure passwords** in `.env` file
+2. **Configure reverse proxy** (Nginx) in front of Next.js
+3. **Enable HTTPS** with SSL certificates
+4. **Set production environment variables**:
+   ```env
+   NODE_ENV=production
+   POSTGRES_PASSWORD=<strong-password>
+   ```
+5. **Backup database** regularly:
+   ```bash
+   docker exec schoolcompare_db pg_dump -U schoolcompare schoolcompare > backup.sql
+   ```
+
+## Network Architecture
+
+```
+Internet
+    ↓
+Next.js (port 3000) ← User browsers
+    ↓ (internal network)
+FastAPI (port 8000) ← API calls
+    ↓ (internal network)
+PostgreSQL (port 5432) ← Data queries
+```
+
+All services communicate via the `schoolcompare-network` Docker network.

+- **Pages**: 4 main pages + 1 dynamic route
+- **Components**: 15+ React components with CSS modules
+- **Libraries**: 3 core libraries (api, types, utils)
+- **Hooks**: 5 custom hooks
+- **Context**: 2 context providers
+- **Tests**: 2 test suites (components + utils)
+- **Config**: 8 configuration files
+- **Documentation**: 5 markdown files

+
+### Modified
+- None (fresh Next.js installation)
+
+### Unchanged
+- **Backend**: All FastAPI code unchanged

+
+---
+
+## API Integration
+
+All existing FastAPI endpoints remain unchanged:
+
+| Endpoint | Usage |
+|----------|-------|
+| `GET /api/schools` | Search/list schools with filters |
+| `GET /api/schools/{urn}` | Get school details and yearly data |
+| `GET /api/compare?urns=...` | Get comparison data for multiple schools |
+| `GET /api/rankings` | Get ranked schools by metric |
+| `GET /api/filters` | Get available filter options |
+| `GET /api/metrics` | Get metric definitions |
+
+**Integration Method**:
+- Server-side: Direct fetch calls in React Server Components
+- Client-side: SWR for caching and revalidation
+- Proxy: Next.js rewrites `/api/*` → `http://localhost:8000/api/*`
+
+---
+
+## Key Features Implementation
+
+### 1. Server-Side Rendering
+- All pages pre-render HTML on server
+- Faster initial page loads
+- Better SEO (content visible to crawlers)
+- Progressive enhancement with client-side JS
+
+### 2. Individual School Pages
+- Each school has unique URL: `/school/{urn}`
+- Dynamic routing with Next.js App Router
+- SEO optimized with meta tags and structured data
+- Shareable links with pre-loaded data
+
+### 3. Search & Filters
+- Name search with debouncing
+- Postcode search with radius
+- Local authority filter
+- School type filter
+- All filters sync with URL
+
+### 4. School Comparison
+- Select up to 5 schools
+- Persistent in localStorage
+- Sync with URL (`?urns=X,Y,Z`)
+- Side-by-side metrics table
+- Multi-school performance chart
+
+### 5. Rankings
+- Sort by any metric
+- Filter by area and year
+- Top 3 visual highlighting
+- Responsive table design
+
+### 6. Maps & Charts
+- **Maps**: Leaflet with OpenStreetMap tiles
+  - Dynamic import to avoid SSR issues
+  - Loading states
+  - Interactive markers with popups
+- **Charts**: Chart.js with react-chartjs-2
+  - Multi-year performance trends
+  - Dual-axis (percentages + progress scores)
+  - Responsive design
+  - Interactive tooltips
+
+---
+
+## SEO Implementation
+
+### Meta Tags (per page)
+```typescript
+export const metadata = {
+  title: 'School Name | Area',
+  description: 'View KS2 performance data for...',
+  keywords: '...',
+  openGraph: { ... },
+  twitter: { ... },
+  alternates: {
+    canonical: 'https://schoolcompare.co.uk/school/123',
+  },
+};
+```
+
+### JSON-LD Structured Data
+```json
+{
+  "@context": "https://schema.org",
+  "@type": "EducationalOrganization",
+  "name": "School Name",
+  "identifier": "100001",
+  "address": { ... },
+  "geo": { ... }
+}
+```
+
+### Dynamic Sitemap
+- Generates sitemap with all school pages
+- Updates automatically on deployment
+- Submitted to Google Search Console (post-launch)
+
+---
+
+## Performance Optimizations
+
+1. **Server-Side Rendering**: HTML generated on server
+2. **API Caching**: `revalidate` option for SSR data
+3. **Image Optimization**: Next.js Image component with AVIF/WebP
+4. **Code Splitting**: Automatic route-based splitting
+5. **Dynamic Imports**: Heavy components (maps, charts) loaded on demand
+6. **Bundle Optimization**: Tree shaking, minification
+7. **Compression**: Gzip enabled
+8. **Remove Console Logs**: Stripped in production build
+
+**Expected Lighthouse Scores**: 90+ across all metrics
+
+---
+
+## Testing
+
+### Unit Tests
+- Jest + React Testing Library
+- Component tests (SchoolCard, etc.)
+- Utility function tests
+- Mock Next.js router and fetch
+
+### E2E Tests (Recommended)
+- Playwright setup ready
+- Critical user flows documented in QA checklist
+
+### Manual Testing
+- Comprehensive QA checklist provided
+- Cross-browser testing matrix
+- Responsive design verification
+
+---
+
+## Deployment Options
+
+### Option 1: Vercel (Recommended)
+- Zero-config deployment
+- Automatic HTTPS and CDN
+- Preview deployments
+- Built-in analytics
+
+### Option 2: Docker
+- Self-hosted with full control
+- Dockerfile and docker-compose provided
+- Nginx reverse proxy setup included
+
+### Option 3: PM2
+- Traditional Node.js deployment
+- Cluster mode for performance
+- Process management
+
+### Option 4: Static Export (Not Used)

+## Scheduled Jobs
+
+### Geocoding Schools (Cron Job)
+
+School postcodes are geocoded by a scheduled job, not on-demand. This improves performance and reduces API calls.
+
+**Setup the cron job** (runs weekly on Sunday at 2am):
+
+```bash
+# Edit crontab
+crontab -e
+
+# Add this line (adjust paths as needed):
+0 2 * * 0 cd /path/to/school_compare && /path/to/venv/bin/python scripts/geocode_schools.py >> /var/log/geocode_schools.log 2>&1
+```
+
+**Manual run:**
+```bash
+# Geocode only schools missing coordinates
+python scripts/geocode_schools.py
+
+# Force re-geocode all schools
+python scripts/geocode_schools.py --force
+```

+# SchoolCompare.co.uk - Project Context
+
+## Overview
+
+SchoolCompare is a web application for comparing UK primary school (KS2) performance data. It allows users to:
+- Search and browse schools by name, location (postcode), or local authority
+- Compare multiple schools side-by-side with charts and tables
+- View school rankings by various KS2 metrics
+- See historical performance trends across years
+
+## Architecture
+
+### Backend (Python/FastAPI)
+- **Framework**: FastAPI with uvicorn
+- **Database**: PostgreSQL with SQLAlchemy ORM
+- **Data Source**: UK Government "Compare School Performance" CSV downloads
+
+Key files:
+- `backend/app.py` - Main FastAPI application, API routes
+- `backend/config.py` - Configuration via pydantic-settings (env vars, .env file)
+- `backend/database.py` - SQLAlchemy engine, session management
+- `backend/models.py` - Database models (School, SchoolResult)
+- `backend/data_loader.py` - Data queries, geocoding, legacy DataFrame compatibility
+- `backend/schemas.py` - Column mappings, metric definitions, LA code mappings
+
+### Frontend (Vanilla JS)
+- Single-page application with hash-based routing
+- Chart.js for data visualization
+- No build step required
+
+Key files:
+- `frontend/index.html` - Main HTML structure
+- `frontend/app.js` - All application logic, API calls, rendering
+- `frontend/styles.css` - Styling (CSS variables, responsive design)
+
+### Database Schema
+
+```
+schools                          school_results
+├── id (PK)                      ├── id (PK)
+├── urn (unique, indexed)        ├── school_id (FK → schools.id)
+├── school_name                  ├── year (indexed)
+├── local_authority              ├── rwm_expected_pct
+├── school_type                  ├── reading_expected_pct
+├── postcode                     ├── ... (all KS2 metrics)
+├── latitude, longitude          └── unique(school_id, year)
+└── results → SchoolResult[]
+```
+
+## Configuration
+
+Environment variables (or `.env` file):
+- `DATABASE_URL` - PostgreSQL connection string (default: `postgresql://schoolcompare:schoolcompare@localhost:5432/schoolcompare`)
+- `HOST`, `PORT` - Server binding (default: `0.0.0.0:80`)
+- `ALLOWED_ORIGINS` - CORS origins
+
+## Running Locally
+
+1. Start PostgreSQL:
+   ```bash
+   docker compose up -d db
+   ```
+
+2. Run migration to import CSV data:
+   ```bash
+   python scripts/migrate_csv_to_db.py --drop
+   # Add --geocode to geocode postcodes (slower, adds lat/long)
+   ```
+
+3. Start the app:
+   ```bash
+   uvicorn backend.app:app --host 0.0.0.0 --port 8000
+   ```
+
+## Docker Deployment
+
+```bash
+docker compose up -d
+```
+
+This starts:
+- `db` - PostgreSQL 16 with persistent volume
+- `app` - FastAPI application on port 80
+
+## Data
+
+- Source: UK Government Compare School Performance downloads
+- Location: `data/` directory with year folders (e.g., `2023-2024/england_ks2final.csv`)
+- The `scripts/download_data.py` can fetch data from the government website
+
+## Key Features
+
+- **Location Search**: Enter postcode to find nearby schools (uses postcodes.io API)
+- **Multi-school Comparison**: Select multiple schools, view metrics across years
+- **Rankings**: Top schools by any KS2 metric, filterable by local authority
+- **Variability Analysis**: Shows standard deviation of scores across years
+
+## API Endpoints
+
+- `GET /api/schools` - List/search schools (supports pagination, location search)
+- `GET /api/schools/{urn}` - School details with all yearly data
+- `GET /api/compare?urns=123,456` - Compare multiple schools
+- `GET /api/rankings` - School rankings by metric
+- `GET /api/filters` - Available filter options (LAs, types, years)
+- `GET /api/metrics` - Metric definitions (single source of truth)
+- `GET /api/data-info` - Database stats
+
+## Recent Changes
+
+- Migrated from CSV file storage to PostgreSQL database
+- Added location-based search using postcode geocoding
+- Added local authority filter to rankings
+- Improved frontend with featured schools, loading states, API caching

+# Deployment Guide
+
+This guide covers deployment options for the SchoolCompare Next.js application.
+
+## Deployment Options
+
+### Option 1: Vercel (Recommended for Next.js)
+
+Vercel is the easiest and most optimized platform for Next.js applications.
+
+#### Steps:
+
+1. **Install Vercel CLI**:
+   ```bash
+   npm install -g vercel
+   ```
+
+2. **Login to Vercel**:
+   ```bash
+   vercel login
+   ```
+
+3. **Deploy**:
+   ```bash
+   vercel --prod
+   ```
+
+4. **Configure Environment Variables** in Vercel dashboard:
+   - `NEXT_PUBLIC_API_URL`: Your FastAPI endpoint (e.g., `https://api.schoolcompare.co.uk/api`)
+   - `FASTAPI_URL`: Same as above for server-side requests
+
+#### Benefits:
+- Automatic HTTPS
+- Global CDN
+- Zero-config deployment
+- Automatic preview deployments
+- Built-in analytics
+
+---
+
+### Option 2: Docker (Self-hosted)
+
+Deploy using Docker containers for full control.
+
+#### Prerequisites:
+- Docker 20+
+- Docker Compose 2+
+
+#### Steps:
+
+1. **Build Docker Image**:
+   ```bash
+   docker build -t schoolcompare-nextjs:latest .
+   ```
+
+2. **Run with Docker Compose**:
+   ```bash
+   # Create .env file with production variables
+   echo "NEXT_PUBLIC_API_URL=https://api.schoolcompare.co.uk/api" > .env
+   echo "FASTAPI_URL=http://backend:8000/api" >> .env
+
+   # Start services
+   docker-compose up -d
+   ```
+
+3. **Verify Deployment**:
+   ```bash
+   curl http://localhost:3000
+   ```
+
+#### Environment Variables:
+- `NEXT_PUBLIC_API_URL`: Public API endpoint (client-side)
+- `FASTAPI_URL`: Internal API endpoint (server-side)
+- `NODE_ENV`: `production`
+
+---
+
+### Option 3: PM2 (Node.js Process Manager)
+
+Deploy directly on a Node.js server using PM2.
+
+#### Prerequisites:
+- Node.js 24+
+- PM2 (`npm install -g pm2`)
+
+#### Steps:
+
+1. **Build Application**:
+   ```bash
+   npm run build
+   ```
+
+2. **Create PM2 Ecosystem File** (`ecosystem.config.js`):
+   ```javascript
+   module.exports = {
+     apps: [{
+       name: 'schoolcompare-nextjs',
+       script: 'npm',
+       args: 'start',
+       cwd: '/path/to/nextjs-app',
+       instances: 'max',
+       exec_mode: 'cluster',
+       env: {
+         NODE_ENV: 'production',
+         PORT: 3000,
+         NEXT_PUBLIC_API_URL: 'https://api.schoolcompare.co.uk/api',
+         FASTAPI_URL: 'http://localhost:8000/api',
+       },
+     }],
+   };
+   ```
+
+3. **Start with PM2**:
+   ```bash
+   pm2 start ecosystem.config.js
+   pm2 save
+   pm2 startup
+   ```
+
+---
+
+### Option 4: Nginx Reverse Proxy
+
+Use Nginx as a reverse proxy in front of Next.js.
+
+#### Nginx Configuration:
+
+```nginx
+server {
+    listen 80;
+    server_name schoolcompare.co.uk;
+
+    # Redirect to HTTPS
+    return 301 https://$server_name$request_uri;
+}
+
+server {
+    listen 443 ssl http2;
+    server_name schoolcompare.co.uk;
+
+    # SSL Configuration
+    ssl_certificate /etc/ssl/certs/schoolcompare.crt;
+    ssl_certificate_key /etc/ssl/private/schoolcompare.key;
+
+    # Security Headers
+    add_header X-Frame-Options "SAMEORIGIN" always;
+    add_header X-Content-Type-Options "nosniff" always;
+    add_header X-XSS-Protection "1; mode=block" always;
+
+    # Proxy to Next.js
+    location / {
+        proxy_pass http://localhost:3000;
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection 'upgrade';
+        proxy_set_header Host $host;
+        proxy_cache_bypass $http_upgrade;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # Proxy to FastAPI
+    location /api/ {
+        proxy_pass http://localhost:8000;
+        proxy_http_version 1.1;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+
+    # Cache static files
+    location /_next/static/ {
+        proxy_pass http://localhost:3000;
+        add_header Cache-Control "public, max-age=31536000, immutable";
+    }
+}
+```
+
+---
+
+## Pre-Deployment Checklist
+

+- [ ] Run `npm test` - all tests pass
+- [ ] Environment variables configured
+- [ ] FastAPI backend accessible
+- [ ] Database migrations applied
+- [ ] SSL certificates configured (production)
+- [ ] Domain DNS configured
+- [ ] Monitoring/logging set up
+- [ ] Backup strategy in place
+
+---
+
+## Post-Deployment Verification
+
+1. **Health Check**:
+   ```bash
+   curl https://schoolcompare.co.uk
+   ```
+
+2. **Test Routes**:
+   - Home: `https://schoolcompare.co.uk/`
+   - School Page: `https://schoolcompare.co.uk/school/100001`
+   - Compare: `https://schoolcompare.co.uk/compare`
+   - Rankings: `https://schoolcompare.co.uk/rankings`
+
+3. **Check SEO**:
+   - Sitemap: `https://schoolcompare.co.uk/sitemap.xml`
+   - Robots: `https://schoolcompare.co.uk/robots.txt`
+
+4. **Performance Audit**:
+   - Run Lighthouse in Chrome DevTools
+   - Target scores: 90+ for Performance, Accessibility, Best Practices, SEO
+
+---
+
+## Monitoring
+
+### Recommended Tools:
+- **Vercel Analytics** (if using Vercel)
+- **Sentry** for error tracking
+- **Google Analytics** for user analytics
+- **Uptime Robot** for uptime monitoring
+
+### Health Check Endpoint:
+The application automatically serves health data at the root route.
+
+---
+
+## Rollback Procedure
+
+### Vercel:
+```bash
+vercel rollback
+```
+
+### Docker:
+```bash
+docker-compose down
+docker-compose up -d --force-recreate
+```
+
+### PM2:
+```bash
+pm2 stop schoolcompare-nextjs
+# Restore previous build
+pm2 start schoolcompare-nextjs
+```
+
+---
+
+## Troubleshooting
+
+### Issue: API requests failing
+- **Solution**: Check `NEXT_PUBLIC_API_URL` and `FASTAPI_URL` environment variables
+- **Verify**: FastAPI backend is accessible from Next.js container/server
+
+### Issue: Build fails
+- **Solution**: Check Node.js version (requires 24+)
+- **Clear cache**: `rm -rf .next node_modules && npm install && npm run build`
+
+### Issue: Slow page loads
+- **Solution**: Enable caching in API calls
+- **Check**: Network latency to FastAPI backend
+- **Verify**: CDN is serving static assets
+
+---
+
+## Security Considerations
+
+- ✅ HTTPS enabled
+- ✅ Security headers configured (X-Frame-Options, CSP, etc.)
+- ✅ API keys in environment variables (never in code)
+- ✅ CORS properly configured
+- ✅ Rate limiting on API endpoints
+- ✅ Regular security updates
+- ✅ Dependency vulnerability scanning
+
+---
