+;; Fetches new envelopes from signal-cli via SSE or JSON-RPC
 ;; and stores them in the local database: incoming messages, messages
 ;; sent from other linked devices (sync), delivery/read receipts, and
-;; typing indicators.  `noise-receive-start-polling' polls on a timer.
+;; typing indicators.  `noise-receive-start-sse' connects to the SSE
