# `.htaccess` → nginx migration
> **Problem:** `public/admin/.htaccess` contained Apache-specific security
> directives that nginx **silently ignores**. None of the rules were active
> in production.
> **Status:** Migrated into `nginx/posterg.conf`

## Rules migrated into `nginx/posterg.conf`
| Apache `.htaccess` rule | nginx equivalent | Location |
|---|---|---|
| `Header always set X-Frame-Options "SAMEORIGIN"` | `add_header X-Frame-Options "SAMEORIGIN" always;` | main `server` block (already present) |
| `Header always set X-Content-Type-Options "nosniff"` | `add_header X-Content-Type-Options "nosniff" always;` | main `server` block (already present) |
| `Header always set X-XSS-Protection "1; mode=block"` | **Intentionally omitted** — deprecated & counterproductive; see `SECURITY_HEADERS.md` | — |
| `Header always set Referrer-Policy "strict-origin-when-cross-origin"` | `add_header Referrer-Policy "strict-origin-when-cross-origin" always;` | main `server` block (already present) |
| `Header always set Content-Security-Policy "..."` | `add_header Content-Security-Policy "..." always;` | `/admin/` location block (**added**) |
| `Options -Indexes` | `autoindex off;` | `/admin/` location block (**added**; nginx default is off, explicit for clarity) |
| `<FilesMatch "^\."> Require all denied` | `location ~ /\.(?!well-known).*` deny | main `server` block (already present) |
| `<FilesMatch "(composer\.(json\|lock)\|error\.log)$"> Require all denied` | `location ~* \.(md\|txt\|sql\|sh\|json\|gitignore)$` deny + `location ~* \.log$` deny | main `server` block (`log` rule **added**) |
| `php_flag display_errors Off` | Handled by `config/bootstrap.php` (`ini_set('display_errors', '0')`) | PHP |
| `php_flag log_errors On` | Handled by `config/bootstrap.php` (`ini_set('log_errors', '1')`) | PHP |
| `php_value error_log error.log` | Handled by `config/bootstrap.php`; should use absolute path (item #9) | PHP |

## Status of `public/admin/.htaccess`
The file is now **dead code** on this nginx server. It has been left in place
(harmless) so it would still work if the project were ever tested behind Apache
(e.g., `php -S` built-in server doesn't read it either). All security rules it
previously attempted to set are now enforced by nginx directly.
