ControlReply.number

number : let number: Int property [source] ¶ property [source] ¶ number: The number tmux stamped on this reply's block.

tmux numbers a command when it runs it, from one counter shared by every client, so a connection's own replies advance without being contiguous. A block that does not advance is a protocol violation rather than a reply, which is what keeps ordering proven rather than assumed.
