BUILT.md gains "Macros: the compiler dlopens the program": the image format and why nothing aggregate crosses to C, quasiquote before the walk and why that is load-bearing, the distinction between a quasiquoted call and a real one, the two different non-termination failures, -linkall and the session-path argument that forced it, the three cost numbers, and what unless proves and what it does not. "Why there is no interpreter" gains its consequence: compile-and-dlopen is a mechanism now rather than an absence. NEXT.md loses the whole expander design and its handoff, which are done, and keeps six things that are not: four special forms left, with why when and dotimes are the hard two -- the prelude uses them 29 and 12 times, so moving either makes the prelude depend on the macro the macro module has to compile the prelude to get; that a macro has no way to say why something is wrong, which is the biggest gap and the reason unless went before cond; macros not imported; a prelude macro not being able to call a macro; nested quasiquote; and gensym's counter per module. One claim corrected rather than left standing: the packages section said the topological package order exists for the expander. The expander does not read it, because macros are not imported. The order is right and correct and nothing uses it yet.
