How this list is built
The finished page will be generated from the actual shipped artifacts so it cannot drift from reality:
- PHP dependencies via
composer licenses. - JavaScript dependencies from the application importmap.
- Bundled system components — Apache, Postfix, Dovecot, PowerDNS, MariaDB, FrankenPHP/Caddy, Valkey — from the package manifests.
