I'm not sure why files in DL_DIR would symlink to the local
(pre)mirrors instead of making an independent copy? Mirrors can indeed
move or disappear altogether.
Can you look into where the symlinking happens, and whether that can
be modified or configured differently (maybe also the git history for
that code)?
Current code is here:
https://git.openembedded.org/bitbake/tree/lib/bb/fetch2/__init__.py#n1096
It is created during handle the (pre)mirrors in do_fetch. And the
history long time ago:
https://git.openembedded.org/bitbake/commit/?id=83f9445081595630488a5d3e170d282a13836c98
About if we can change to independent copy, I need to do more research,
welcome to provide me some
background and notes.

When there are tarballs in local mirrorfile://, do_fetch will
create symlink under DL_DIR, eg:
pseudo-prebuilt-2.33.tar.xz ->
/project/path/to/localmirrorA/pseudo-prebuilt-2.33.tar.xz
after user update path from localmirrorA to localmirrorB, because
do_fetch don't depends on PREMIRRORS/MIRRORS, do_fetch will not
be rerun, so the symlink will not update to:
pseudo-prebuilt-2.33.tar.xz ->
/project/path/to/localmirrorB/pseudo-prebuilt-2.33.tar.xz
then, do_upack will failed since the tarball cannot be found.

Changing PREMIRRORS or MIRRORS should not change the output of the
task, ever, so do_fetch shouldn't depend upon them.
The failure case I met is like this:
I have a project with PREMIRRORS setting, and the tarballs are under it.
PREMIRRORS:append ="file:///project/path/to/localmirrorA"
after first bitbake pseudo-native, there will a symlink under DL_DIR:
pseudo-prebuilt-2.33.tar.xz ->
/project/path/to/localmirrorA/pseudo-prebuilt-2.33.tar.xz
Then, Since all the tarballs are moved to /project/path/to/localmirrorB
I changed PREMIRRORS:append ="file:///project/path/to/localmirrorB"
Then bitbake pseudo-native again, do_fetch will not rerun since no
signature change.
do_unpack rerun since one dependency change, it will try to unpack
${DL_DIR}/pseudo-prebuilt-2.33.tar.xz,
but since do_fetch not rerun, ${DL_DIR}/pseudo-prebuilt-2.33.tar.xz
still point to localmirrorA, but localmirrorA not exist
since localmirrorB replace it. Then will cause do_unpck failure:
NOTE: Unpacking /build/downloads/pseudo-prebuilt-2.33.tar.xz to
/build/tmp-glibc/work/x86_64-linux/pseudo-native/1.9.0+git xz:
/build/downloads/pseudo-prebuilt-2.33.tar.xz: No such file or directory
So this is why I want to add this depends, and want to make do_fetch
rerun and resymlink to /project/path/to/localmirrorB
