Tree snapshot of d9c62a8 (2026-08-18). The 20 source commits between
16ef583 (c9) and d9c62a8 were never pushed and the clone that held them
was lost; this commit carries their combined tree verbatim so the build
history stays auditable from the c1–c9 commits below it. Original
hashes as recorded in the session handoff:

Drive the c5 machines as straight-line code on the path (D8): dial_handshake
and accept_handshake do the IO on a shared FramedConn, and a connection actor
is spawned only after a successful handshake. Rejects, tie-break losses (D7),
protocol faults and timeouts are all resolved on the path by closing, so no
actor ever exists for a connection that did not establish. The whole
FramedConn travels into spawn_established, carrying any read-ahead past the
handshake frames.
Handshake deadlines land here rather than in c6c: FramedConn::recv_deadline
enforces them between reads via the connection's fd arm, so a peer that
connects and goes silent cannot wedge the acceptor.
Connection lifetime moves to the manager (pulled forward from c7). The path
registers each established connection and hands over its ConnHandle; the
manager owns it, monitors the actor, and tears the connection down on
Disconnect, on peer close, or at manager shutdown. spawn_established returns
a Pid, so a connection neither outlives nor dies with whichever actor
established it — the ownership that made two-node teardown unorderable.
The manager also tracks in-flight dial intents, monitored so a panicking
dial cannot wedge the tie-break, and answers HelloCtx for the accept path.
