when flying kitten stand where baritone try to build baritone get stuck but kitten not real so baritone should be able to place block anyways

literally unfixable

proxy should put a digital signature (ECDSA) in the nametag of the cat, attesting to the current timestamp (must be within 5 seconds), and the name and color of the cat, proving to baritone that the cat is an ethereal projection of the mind, and not actually a feline that a block could collide with in the server's point of view.

oh and the cat's entity ID is signed too

entity id is negative i think that good enough 👍

no, consider the following attack vector:

server anticheat sends a negative entity ID to test if you are using baritone. this succeeds, and the player is banned.

this would not happen in my proposed solution, because only the correct proxy server can create a digital signature that bypasses baritone's checks
