Z-12 should go to both sender and recipient.

Hello. Based on the feedback I received from you, I compiled the Nostr diagram into one page.
There are quite a lot of elements, so I'll just show you the line drawings for now. (I plan to add color once the contents are finalized)
In this illustration, the ostrich was not included in the cast. Instead, machines and robots are used to represent the internal workings of clients and relay servers. I also researched and added Zap while getting advice from various people.
What do you think of this diagram?

Thank you for your advice. Z-11 and Z-12 are certainly as you say.
I think rather not. The receiver is not involved at all (except for publishing a zappable pubkey to a common relay). This is the nice thing about Bitcoin in general, isn’t it?
