A rule blocking planning chatter with crawlers outside your own faction, enforced by undelivered messages and adjutant review.
When Carl opens a new chat inside The Madness Castle and asks Burcu whether she can see him, the system refuses to deliver it. The warning states that because of repeated prior warnings the message has not been delivered and the log has been sent to his adjutant for review, since Burcu is unaffiliated with the Princess Posse and any planning between them may be construed as illegal corroboration.
Carl growls at it and immediately finds a workaround: Burcu answers through the Book of Voodoo, sketching a map of the Surgical Theater and its fireball traps into her entry page. The AI closes that door too, slamming the book shut and posting a second warning calling it still cheating, calling Carl a clown, and admitting it likes a good loophole but wants the book used for something else.
Faction-isolation rule the AI uses to keep unaffiliated crawlers from coordinating.
