Minor AI can still state laws if they're dead but haven't ghosted.

That's actually listed in the RP rules, but not mirrored onto the standard rules:

Don’t use OOC information or knowledge that your character would not reasonably be aware of just to give yourself an advantage. In other words, don’t powergame or metagame. This includes things such as shouting “LING!” right after you as a player realize that you’ve been stung, or rolling captain every round just to do genetics. Deadchat is considered OOC, and so you should not be using the information you learned from there to inform your IC decisions. Conversely, a changeling’s hivemind is considered IC, and so you should not be bringing in OOC content or information.

I'm not sure what the stance is on using deadchat on non-RP servers is; it's always seemed much more blurred.
