> -know what information can be retried.
+Each endpoint advertises a different max_idle_timeout, but the effective value
+is determined by taking the minimum of the two advertised values. By announcing
+a max_idle_timeout, endpoints commit to initiating an immediate close
+({{immediate-close}}) if it abandons a connection prior to the effective value.
+
+An endpoint restarts any timer it maintains when a packet from its peer is
+received and processed successfully.  The timer is also restarted when sending
+a packet containing frames other than ACK or PADDING (an ack-eliciting packet;
+see {{QUIC-RECOVERY}}), but only if no other ack-eliciting packets have been
+sent since last receiving a packet.  Restarting when sending packets ensures
+that connections do not prematurely time out when initiating new activity.
+
+An endpoint that sends packets near the end of the idle timeout period
+risks having those packets discarded if its peer enters the draining state
+before the packets arrive.  If a peer could time out within an Probe Timeout

I'm not introducing this text, it just moved, hence the different PR, which is editorial.
