The wg interface would not send packets, but there was no indication of why. I've been trying to debug this (intermittently) since May. Someone on the OpenWRT mailing list today suggested that a lack of entropy might be the problem. Adding "haveged " fixed the problem and the interface now seems to work just fine. It would be *very* helpful if wireguard reported in the system log that it can't come up due to a lack of entropy. Thanks.
