:: %sane: sanity checker for the landscape suite of applications
::
:: Userspace currently uses certain identifiers as foreign keys, and
:: expects those foreign keys to exist in a number of locations.
::
:: These foreign key relationships are prone to breaking during OTAs
:: and there are enough of them that they rarely get tested for
:: manually. %sane is a gall app that will check the validity of
:: these relationships, and fix them if asked.
::
:: Sane has a companion thread, -sane, which should be run instead
:: of attempting :sane %fix directly from the dojo.
::
:: Pokes:
:: %fix - Find issues and fix them
:: %check - Find issues and print them
::
:: Currently validates:
:: - Entries in {contact,metadata,group} stores are in sync with
:: their hooks
:: - Each group has its associated metadata and contacts
:: - Each graph is being synced
