It seems to me you reviewed the text, its much clear now (I read it at publishing and got stuck half way by confusion)
It amazes me how far you go and how masterfully you make use of word associations.
Suggestion: mystery clocks. I have seen that at Daydreamer RPG (the one spun from FU): the clock exists, but you dont know when it will trigger (it calls them Hidden Springs). How would you go about it? Daydreamer implements it by automatic trigger at 3 "no, and..." iirc. I have a feeling you can iterate on top of this proposal.
I have been re-reading the blog posts because I am getting ready to try to play again soon, and after digging many systems, yours strikes me as the cleanest on play advice, which is something I struggle still today.
And answering the last thoughts: I think you should at least mention the palace and major systems when you are already introducing complex mnemonics such as these in this post
