The probe answers one protected endpoint and pings Werk once an hour, so the status stays fresh. Werk sees:
- WordPress and PHP versions, the active theme and the plugin list
- the last lines of the error log and the health of WP-Cron
- the size of the uploads folder and the free disk space
The probe reads this data. It writes nothing to your site, with three exceptions: the Werk AI connection, calendar drafts and Werk test sessions.
