An object at a deleted key is not always the one the delete meant: a
rename copy can land before its filer entry is visible, and a rewrite
can upload over it. When the event recorded no remote stamp, or the
live stat cannot confirm the recorded etag, the delete now keeps the
object instead of treating it as a late upload.
