fsck UNREF FILE

After my OpenBSD 7.2 box lost power, bootup halted when rc ran fsck
which reported problems with inodes. At the root prompt, I ran fsck and
answered 'y' to each prompt. Now, in normal mode, running fsck reports a
few unreferenced files, auto-answers "no" to its "CLEAR?" prompt, and
continues.

$ sudo fsck

Why does fsck say "NO WRITE" for each partition? Is this why it
auto-answers "no" to the "CLEAR?" question?
