MEMBERS Attach to One Chip and the Attached Device Becomes the Terminal — POS, Kiosk and Kitchen Screen at Once
One server stood up beside the payment terminal already in the shop, with a tablet, a PC and a kitchen screen attached. No app was built for any of the three, and each became a kiosk, a POS and a kitchen display. The card authorisation path was not touched by a single line. Full code, run log, and the three screens exactly as rendered.
MEMBERS Boards Hand Over Their Screens — Two Real Devices, Two Transports, One Client
The STM32H723 over USB serial, the ESP32 discovered by mDNS and attached over Wi-Fi TCP. Each board hands over its own screen definition, and pressing a button turns a real LED on. The client code does not differ by a character between the two. No simulator — in this piece alone, verification fails without hardware.
OPEN What You Do Not Expose Protects the App — Every Server Is an App, and What Comes After
A server becoming an app does not mean putting every capability on a screen. What you never turn into a tool is the shape of that app, and its safety. We made that argument in 2026-04 and deferred it with "the next pieces will show you". This time we do not defer — that a capability absent from the tool list really cannot be reached is paid back in execution logs and a real board's answers.
