This chapter headed "LilyPond Scheme Interfaces" would be most useful to the tyro since it would help to get information into and
out of music streams.

However it is missing from the 2.18.2 documentation which relates to the 2.16.2 release.

Inside the 2.18.2 source download there is a file scheme-tutorial.itely which refers to the 2.17.11 unstable version. This is
somewhat different from the above but still has no chapter "LilyPond Scheme Interfaces"

Is there an intention to provide this chapter or is it a low priority for the experts?

 I think it would be very useful, I don't know of anybody actively working on it.  Speaking as somebody who could contribute to this section, I wouldn't know where to begin!

One issue here is that there is much to work on in LilyPond and a rather small pool of contributors.

Still battling on to fathom a way to recover key signature details for mods to enharmonic.ly - currently pondering
key-signature-interface.cc

As far as I can tell, enharmonic.ly is not a file in the distribution--where are you getting this?  From other threads of yours which include the code, it seems you are referring to the snippet  http://lilypond.org/doc/v2.18/Documentation/snippets/pitches#pitches-transposing-pitches-with-minimum-accidentals-_0028_0022smart_0022-transpose_0029

As far as your quandary, what are you trying to do?  Maybe I or someone else can provide some insight.

Best,
