The session records the sequence of the Connect that started its generation. A
Connect repeats exactly when the session is connected and carries that
sequence; anything else ends the generation, forgets the peer and accepts a new
one. AcceptConnect answers both, ConnectRepeats is the predicate for servers
that keep one session per peer, and AnswerRepeatedConnect is private. Server
mode admits a Connect from a new endpoint and the session decides; the listener
no longer compares payloads (the payload stays application evidence).
CreateConnect on a session that has had a peer starts a new generation. An
Accept counts only while the Connect is pending and only if it names it. The
watermark is seeded by the Connect or Accept alone; reliable data before that
is neither remembered, acknowledged nor delivered. The default initial sequence
is random in [1, 2^31) in every options type. An ICMP connection reset no
longer sets DisconnectReason: nothing ended. The interop peer flushes before it
disconnects.
