Meta's Crawler Goes Live Oct 30. Your Real Deadline Is Oct 29.

After the deadline, monitor logs for the meta-externalagent user-agent to distinguish between Meta AI citation, link preview, and training crawlers.
Regularly review and update rules to avoid drift and ensure compliance with Meta's contractual obligations.
