way at the end is your answer: \accidentalStyle forget

I am working on a psalm set to written-out Anglican chant, for which I

I understand from reading previous threads that \bar commands simply
add the visual appearance of a bar line. On the back end, as I gather,
LilyPond does not treat a \bar event as a measure demarcation for the
purposes of accidentals.
This is causing problems in my score, as noted in the below MWE.
Ideally, I’d like to use the choral-cautionary accidental style, but
with LilyPond treating every barline as the end of a measure.
For now, I have to use a bunch of exclamation marks and question marks
to control accidental appearances manually. Is there a better way?
My best idea right now is to “temporarily re-enable timing and use
\partial to create a tiny measure” (see the documentation
<https://lilypond.org/doc/v2.24/Documentation/notation/displaying-rhythms#unmetered-music>).
But I’d prefer a solution that doesn’t require me to clutter up my
code every time I come across some accidentals. Another option: In
this message
<https://lists.gnu.org/archive/html/lilypond-user/2013-03/msg01162.html>,
Harm suggested \once \accidentalStyle forget. That works, except that
I’d have to remember to do it in all places like the downbeat of
“measure” 2. And it doesn’t include the smart parentheses of the
-cautionary styles.
