fort_cache_purge is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Wordpress, apply this rule, and every fort_cache_purge call is checked against it from then on.
