Field notes
The chamber is a 128 × 128 cell world with controls to pause, advance a step, add energy, and choose presets including Lone glider, Living garden, Parallel pair, and Random field. Learning is off by default; the optional Q-learning caretaker explores light and mutation settings from mass-change feedback and may accelerate collapse. Saves stay on the device, and the research section links benchmark logs, CSV data, and a protocol.
