Interesting Marks On Prokofiev Editions

[flyusx]

Hey all,
I've noticed some interesting marks on some of my Prokofiev editions from Compozitor SpB that I can't seem to decipher. In the three instances, they appear as ∨ right beside notes or rests, which causes me to think it might not be a misengraving. I've attached images below. Here are their locations:

Sonata №2, Mvmt 1, Measure 206 in the treble clef. 2nd Edition (2021)
Sonata №5, at the very end of Mvmt II before 'pp' in the treble clef and a sextuplet of 64th notes. Same edition as above.
Vision Fugitives №6, Measure 2 (excluding the upbeat). Cover says 2018, inner cover says 2002-2005.

I have different Soviet edition, and it is there as well.
This sign means martele - play non-legato and abrupt sharply in the end IMHO. If the note is alone, you can say it is like a long staccato (for the full note duration). If this is a last note in a slur it means abrupt it sharply.

I don't actually know the answer, but looking at the context my instincts say it's a breath mark (breath marks are usually a comma, but can also look like in your example).

[kosulin]

In addition to what I wrote above, you might want to listen to how Richter plays Visions Fugitives #6. He definitely knows how to play Prokofiev.

Interesting. I do see breath marks in my music. Is there necessarily a difference between the two?

I listened to all three occurrances online. The wedge mark appears after a ritenuto, so I don't really know how a breath mark would factor in (logically, a ritenuto extending over several bars would suggest a pause more than a breath?), and both Richter and Berman play into the ritenuto. As for the one in the fifth sonata, I didn't hear much of a breath between the second to last and last sixteenth note in the left hand; the eighth note prior was much more pronounced.
I couldn't hear much of an extra pause with regards to the Vision Fugitives.

Is the general consensus that it's not a misprint?

[kosulin]

I am positive that this is not misprint, this is martelle.
So you play it not as powerfully as martellatto, but abrupt sharply. He placed it over rests to mark exactly where its sharp detachment applies to IMO.
One of his style specifics which Soviets named  "Prokofiev's hammerism".

I am positive that this is not misprint, this is martelle.

Given that the mark is not attached to a note in any of the OP's examples, this seems unlikely.
