Fold the handshake timer lifecycle (msg1 retransmit + timeout/stale reap) through the per-peer machine, re-expressed onto the XX handshake surface. - Route peer-machine removal through remove_peer_machine so each link's timer store is dropped together with its machine (choke-point). - Home the msg1-retransmit decision on the machine-armed retransmit timer; advance the resend counter only on send success and relocate the operator-visible resend count onto the machine. - Reap outbound handshake timeouts via a presence-scan over the machine HandshakeTimeout timer, reading the threshold from config each tick so the reap stays neutral for any handshake_timeout_secs. Cancel both dial-armed handshake timers on outbound promote so a promoted machine carries no stale timer entry. Preserve the guard that suppresses a msg1 resend at a peer already promoted via the inbound cross-connection path. The XX inbound HandshakeTimeout presence-scan is neutral only because the inbound establish path sends msg2 inline and never dispatches the inbound machine event, so no inbound leg ever populates a HandshakeTimeout timer. A future change that drives inbound establish through the machine must re-verify the reap equivalence for inbound legs.
