What happens on activation

When WPLM activates it:

1. Creates 15 database tables (all prefixed wp_wplm_).
2. Generates cryptographic secrets:
   • Ed25519 signing keypair (public key exposed via REST; private key stored off-autoload)
   • AES-256-GCM encryption key for stored license strings
   • HMAC-SHA256 fingerprint anonymization secret
   • Webhook signing secret
3. Seeds default settings.
4. Registers WP-Cron events for renewal processing, zombie culling, and webhook retries.

Uninstallation

Deactivating the plugin pauses cron jobs but leaves data intact. To remove all data, go to Settings → Tools and enable Remove all data on uninstall before deleting the plugin.
