Open it, and you see everything.
Project Magenta Brain shows every message as it passes. Which panel sent it. Which program got it. When.
A dead key is no longer an afternoon of guessing. You look. You see where the message stopped.
Brain holds the line to every panel. If one drops, Brain says so, and when. Then it connects again by itself.
Brain speaks plain text over the network. One line per message. A terminal window is enough to read it and to test it.
That was a choice. We intend to publish it. Any hardware maker can then connect a panel to Project Magenta by reading one document.
Use all of your simulator.
To be continued.
