Browser-rendered windowed desktop for microcontrollers: the firmware describes apps, windows and widgets (retained tree) and a web app draws and operates them over WebUSB / Web Serial; plus a stdout/stderr log capture ring
Point-to-point UDP datagram transport for ESP-IDF v6.0.x. One socket, one peer, one stream: a 12-byte header with sequence number and session, strict validation of every received datagram, zero-copy send and receive, and a receive timeout that never ends early. No tasks, no callbacks, no buffering, no retransmission: it reports loss and restarts, you decide.
