+// TestBroadcastSelfJoinParticipantCarriesSelfInviter pins the fix for "joined a broadcast channel but
+// no dialog appears". A broadcast join emits no service message; the official client materializes the
+// chat-list entry by generating a LOCAL "you joined this channel" service message, which it only does
+// when channel->inviter is a valid user — set from channels.getParticipant(self).inviter_id. Real TG
+// returns inviter_id == user_id (self) for a self-join. telesrv previously left InviterUserID==0, so
+// the client never generated the joined message and the channel stayed out of the list.
