**SECTION 4: `/provision`**, the heart of your ISP automation engine.
This is where service activation, vendor routing, event streaming, firmware pushes, and config backups all come together.

Each file is labeled and complete.


This includes:

- `provision.php` (universal provisioning engine)
- `service_activation.php`
- `event_stream.php`
- `firmware_push.php`
- `config_backup.php`
