### Files Modified

**1. config/bootstrap.php** (NEW)
- Central path configuration
- Defines APP_ROOT, PUBLIC_ROOT, DATABASE_PATH, etc.
- Helper functions: view(), getDatabase()
- Environment detection (dev vs production)
- Error handling configuration

**2. public/*.php** (3 files updated)
- index.php: Uses bootstrap, updated require paths
- search.php: Uses bootstrap, updated require paths
- memoire.php: Uses bootstrap, updated require paths
- All now use view() helper for header/footer

**3. public/admin/*.php** (7 files updated)
- add.php, edit.php, formulaire.php, import.php
- index.php, publish.php, thanks.php
- All updated to use ../../ paths for lib access
- Bootstrap added where needed

**4. justfile** (Updated)
- Dev server: `php -S 127.0.0.1:8000 -t public/`
- Deploy: Now deploys to `/var/www/posterg/`
- Database deploy: Updated paths to `/var/www/posterg/`
- Nginx deploy: Checks for correct DocumentRoot

**5. nginx/posterg.conf** (Updated)
- DocumentRoot: `/var/www/html` → `/var/www/posterg/public`
- Admin location: `/formulaire/` → `/admin/`

**6. .gitignore** (Updated)
- Added var/ directory patterns
- Keeps .gitkeep files, ignores contents

### Security Improvements

**Before:**
- ❌ All files in DocumentRoot (/var/www/html/)
- ❌ Database accessible at /storage/test.db
- ❌ Config files accessible
- ❌ Dev server exposed everything
- ❌ Relied on nginx deny rules

**After:**
- ✅ Only public/ in DocumentRoot
- ✅ Database physically outside web root
- ✅ Config files physically private
- ✅ Dev server matches production security
- ✅ Physical separation = secure by default

## 🧪 Testing

### Local Development
```bash
# Start dev server
just serve

# Test in browser:
# - http://localhost:8000/ → Should work
# - http://localhost:8000/admin/ → Should work
# - http://localhost:8000/storage/test.db → Should 404 ✅
# - http://localhost:8000/config/ → Should 404 ✅
# - http://localhost:8000/../storage/test.db → Should 404 ✅
```

### Security Verification
```bash
# These should all return 404:
curl http://localhost:8000/storage/test.db
curl http://localhost:8000/config/bootstrap.php
curl http://localhost:8000/vendor/autoload.php
curl http://localhost:8000/../storage/test.db
curl http://localhost:8000/lib/Database.php
```

### Production Deployment

**BEFORE deploying to production:**

1. **Update nginx config on server:**
   ```bash
   # Edit /etc/nginx/sites-available/posterg
   # Change: root /var/www/html;
   # To:     root /var/www/posterg/public;
   ```

2. **Create new directory on server:**
   ```bash
   ssh posterg "sudo mkdir -p /var/www/posterg"
   ```

3. **Deploy application:**
   ```bash
   just deploy
   ```

4. **Deploy nginx config:**
   ```bash
   just deploy-nginx
   # Then on server:
   ssh posterg
   sudo bash /tmp/deploy-production.sh
   sudo systemctl reload nginx
   ```

5. **Verify:**
   ```bash
   just server-status
   curl -I https://posterg.erg.be/
   curl -I https://posterg.erg.be/admin/
   curl -I https://posterg.erg.be/storage/test.db  # Must 404!
   ```

## 📝 Path Reference

### From public/*.php files:
```php
<?php
require_once __DIR__ . '/../config/bootstrap.php';  // Bootstrap
require_once LIB_ROOT . '/Database.php';             // Library
$db = getDatabase();                                  // Database
view('header.php', ['pageTitle' => 'Title']);        // Template
```

### From public/admin/*.php files:
```php
<?php
require_once __DIR__ . '/../../config/bootstrap.php';  // Bootstrap
require_once LIB_ROOT . '/Database.php';               // Library
```

### Available Constants (from bootstrap):
- `APP_ROOT` - /path/to/posterg-website
- `PUBLIC_ROOT` - /path/to/posterg-website/public
- `CONFIG_ROOT` - /path/to/posterg-website/config
- `DATABASE_ROOT` - /path/to/posterg-website/database
- `DATABASE_PATH` - /path/to/posterg-website/storage/test.db
- `RESOURCES_ROOT` - /path/to/posterg-website/resources
- `LIB_ROOT` - /path/to/posterg-website/lib
- `VAR_ROOT` - /path/to/posterg-website/var
- `CACHE_ROOT` - /path/to/posterg-website/var/cache
- `LOGS_ROOT` - /path/to/posterg-website/var/logs
- `VIEWS_ROOT` - /path/to/posterg-website/resources/views
