mind-copying

This chapter appears to be a set of notes and reflections rather than a traditional narrative segment, focusing on speculative ideas about copying a character named Pham and the analysis of an entity called the Old One in terms of its coupling and size. It also references the Slow Zone as a 'cradle of thought' and hints at a scene where Ravna attempts to help Pham recover from a psychological state. The chapter title 'Gray Code' is noted but its significance remains unclear within this context.
