Possibly you have a setting configured that affects the behavior of
Git via the MinGW-w64 runtime, such that calling mkdir() ends up
calling NtSetInformationFile() to set the FileCaseSensitiveInformation
for the directory.

It is a mount option for MSYS or cygwin controlled parts of the file system. posix=1 switches case sensitivity on, posix=0 switches it off. MSYS or cygwin are then make caseSensitiveInfo "inheritated" by setting this flag for all newly created directories. This is a feature of the latest cygwin-dll. It might not be seen on older variants.

Does the mkdir command in Git bash create a case-sensitive directory?
It doesn't for me. I have to manually enable case sensitivity via
`chattr +C`.

What do you get for `which git` and `git --version`?

     $ which git
     /mingw64/bin/git

     $ git --version
     git version 2.41.0.windows.1

the same:
$ which git
/mingw64/bin/git

$ git --version
git version 2.41.0.windows.1

And in cmd.exe:
+>where git
C:\Program Files\Git\bin\git.exe

+>git --version
git version 2.41.0.windows.1

$ fsutil file queryCaseSensitiveInfo .

The MSYS2 environment includes lsattr and chattr commands, with the
case-sensitive flag mapped to "C". It's probably more convenient than
typing `fsutil file queryCaseSensitiveInfo` or `fsutil file
setCaseSensitiveInfo`.

     $ lsattr -d test
     ------------ test
     $ chattr +C test
     $ lsattr -d test
     -----------C test

True. But if you frequently change between environments fsutil is the command working in cmd.exe as in git-shell.

core.ignorecase is not regarded in any way. It does not mater if it is
set or not.

Git tests the case-sensitivity of the target directory to configure
core.ignorecase when cloning a repo. If it's case insensitive, then
core.ignorecase is enabled. This overrides the global value. AFAIK,
the ignorecase setting is unrelated to actually setting the case
sensitivity of created directories; it just affects how Git behaves on
a case-insensitive filesystem.
