The closest I'v seen to what you describe is the Call-A.P.P.L.E.
"All About Applesoft" volume, and though it has useful descriptions
of the functions of many Applesoft entry points, it is not a thorough
dissection of the ROM.

It focuses more on entry points that are likely to be used in a M/L
extension to Applesoft than on the "housekeeping" routines.

It is a good complement to a ROM disassembly, however.

$D6A5 is the start of the LIST routine in the ROM.  That would
be a good place to start looking.
