Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See
https://orgmode.org/manual/Feedback.html#Feedback
Your bug report will be posted to the Org mailing list.
------------------------------------------------------------------------
It follows a possible org chunk that reproduce the phantom newlines that
are created while trying to move a headline from a state where there
are no newlines between the headers.

Could you please provide more information?
Which headline should I move to reproduce the problem?
I tried to move headlines randomly in the attached file (your example)
but I do not see any newlines created.

Thanks!
Unfortunately, I am unable to reproduce.
I started from the latest main branch of Org
(https://git.savannah.gnu.org/cgit/emacs/org-mode.git/) running
make repro
Then, opening a new org file and following the steps.

Note that I moved point _before_ headline d as indicated by @, not like
you described in words.
