 The per-IP connection and `SEND` limits of §10 have no analogue. Reticulum gives a server no stable handle on an initiator that does not identify itself, and that is the point: a sender is absent from the wire format by construction (§5.2), and a transport that reintroduced a durable sender identifier would undo it.

+- A server MUST NOT require Reticulum link identification for any operation. It proves a Reticulum identity rather than a smolmail one, and a durable one is exactly the handle this section says a server must not have.
 - A server SHOULD limit requests and bytes per link, and cap concurrent links. Reticulum enforces neither.
 - A server SHOULD keep a global `SEND` ceiling in place of the per-peer one.
 - The per-accept-token `SEND` limit of §10 is unchanged and becomes the main defence. It never needed a peer identity: a token is issued by the mailbox owner (§5.8), which is exactly the handle this transport still has.

-# Smol Mail over WebSocket annex
+# smolmail over WebSocket annex
 
 This annex is not part of the protocol. It adds no version, no section, no address form and no label, and a server that ignores it is fully conformant. It records one convention for carrying the transport of §4 through a WebSocket, so that browsers, which cannot open TCP sockets, and clients on networks that pass only port 443 can reach a mailbox, and so that independent implementations of that carriage agree. The keywords below bind only an implementation that claims to follow this annex. Section references are to [SPEC.md](SPEC.md).
