Copied from my comment on GitLab:
It seems that the programming error re: dynamics actually obscured some
other problems I encountered in my project. I had assumed that there was
only one fault at play here, but there's more to it than I thought.
MIDI ends late if \fine followed by a pitch.
\version "2.23.10"\score { \unfoldRepeats \repeat segno 2 { c'1
\volta 2 \fine 2 2 } \layout { } \midi { }}
This produces correct sheet music but the MIDI file contains 4 notes
(ending one note *after* the \fine). No errors are logged. Changing the
second bar from 2 2 to r1 causes the MIDI output to behave as expected,
ending after the 2nd C without an extraneous rest.
Beaming and \fine
There's something funky going on with beaming: changing the 2nd bar from 2 2 to
8[ 8] 4 2 returns a couple of errors, but claims to compile successfully
and returns expected sheet music. Again, the MIDI output erroneously
includes the first note after the \fine on the 2nd repeat.

Multi-measure rests
This one is very strange.
\version "2.23.10"\score { \unfoldRepeats \repeat segno 2 { c'1
\volta 2 \fine R1 } \layout { } \midi { }}
Errors in the log during MIDI processing, but the output seems correct
(MIDI file ends after \fine instead of including extraneous rest).
