Field notes

The project turns a message into a traceable Brainfuck execution: Alice’s input enters a framed message, the server program processes it, and Bob’s side displays the result. The interface exposes eight working memory values and a 4,199-instruction .bf program, with replay controls ranging from jump-ahead playback to single read/write steps. The page also offers client and server source files and a complete project-and-tests download.
