The problem is that I don't know where to locate the bug. The
difference appears to be that \voices creates a \context Staff wrapper
around the parallel construct. I suspect that the idea is to help with
continuing voices, like if you compare the outputs of
{ << { \voiceOne e'2~ \oneVoice } \new Voice { \voiceTwo c'2 } >> e'2 }
{ \voices "",2 << { \voiceOne e'2~ \oneVoice } \\ c'2 >> e'2 }
The second clearly looks more sensible, but if you look closely, there
still isn't a tie, so the voice does not actually continue in this
situation. So this situation still is not helped in any manner, and the
one thing \voices has over unadorned << \\ >> is that it takes named
contexts.
Clearly this discrepancy is worth removing; I just don't know right now
why it exists in the first place. I must have been thinking something.™
Now independent from the two constructs differing by a \context Staff
wrapper (added in voicify-music in scm/music-functions.scm).
What is additionally puzzling is that either change is accomplished by
voicify-music, so why is one use affected and the other not? Or does
this happen when voicify-music is applied multiple times (the second
time during scorification)?
All this appears mostly unrelated to \tuplet tripping over one but not
the other incantation.

Looks like a bug, so please file a report.

Says who? Are you saying that your proposed variant is wrong as it does
not differ in that regard?

I don't know, but what I meant to say is that this use of \tuplet
outside of \voices or a split into multiple voices seems to me to be
"undefined behavior" ("unspecified"?).

How is

improper while
\tuplet 3/2 << { \voiceOne d''4 c'' es'' \oneVoice }

Re: Where is my tuplet bracket?
Dear David,
This seems like an improper/unintended use of \tuplet. I would have used
\scaleDurations instead.
However, if you slightly modify the mwe as shown below, the tuplet
bracket is shown.
Thanks,
