** WEBPAGE: phantoms
**
** Show a list of all "phantom" artifacts that are not marked as "private".
**
** A "phantom" artifact is an artifact whose hash named appears in some
** artifact but whose content is unknown.  For example, if a manifest
** references a particular SHA3 hash of a file, but that SHA3 hash is
** not on the shunning list and is not in the database, then the file
** is a phantom.  We know it exists, but we do not know its content.
**
** Whenever a sync occurs, both each party looks at its phantom list
** and for every phantom that is not also marked private, it asks the
** other party to send it the content.  This mechanism helps keep all
** repositories synced up.
**
** This page is similar to the /bloblist page in that it lists artifacts.
** But this page is a special case in that it only shows phantoms that
** are not private.  In other words, this page shows all phantoms that
** generate extra network traffic on every sync request.
