>>No need to necessarily subsume the "Adapt" chapter into the "Compose" chapter.
It's still a merging of the two chapters, which affects diagrams and any number of pages. My feeling is that we are in the eleventh hour in the production of the first version of the handbook, and we can't make large changes to the structure. I am in favor of the doing something closely along what you've proposed in the second edition (though I might flatten the indentation a little, but the essence would be there).
>>Suggestion: rename page to "Quality" to be consistent with equivalent section in previous chapter (done).
I've made some changes to be more inclusive of different mediums, because it was originally written for writing only.
