It is loose. Nothing uses it in this repository. What do you need to
repair it for?

the directories directly under .git/objects contain the first bytes of
sha1, to use filesystem in a more efficient way. git-fsck expects an
sha1 (or a reference).

Try running moving the corrupt object (with its *whole* name) some
place else and run git-fsck --all.
