My mentioning of "ls-tree" is only about what needs to be done at the
conceptual level. In practice, assuming that notes trees have mostly the
same fan-out structure, you would run "diff-tree -r" of (base,ours) and
(base,theirs) pair _without_ anything fancy like rename detection, and
pick out pieces (one tree may have ab/cdx{36} while the other tree may
have abcd/x{36} that are notes about the same object---you treat this as
if it is a partial ls-tree output that pertains only to the different
parts, and make canonical "list of annotated objects" by removing '/'.
All of this is very specific to merging "notes" and normal "merge" does
not even want to know about it; I don't think you can avoid doing this
yourself without touching "merge" if you want to merge "notes" correctly.

Got it. Brilliant, and obvious, really, when I think about it...

Agreed. From your feedback, I now have a much clearer picture on how to
proceed. Thanks! :)
Have fun!
