I think the cause was when I moved to an SSD in this laptop and
created the filesystems on the new disk by hand.

This is exactly the case.  What's confusing is the inconsistent use
of the '/usr' (unmounted) and '/usr' (mounted) modes depending on
circumstance.  ie, non-root can cd and ls to '/usr' (mounted), but
not '/usr' (unmounted), but can't resolve a relative symlink in
that path.
