zed relationship read virtualcard parent creditcard:cc_9MSTeIVLW0C6aHtiQSolob --insecure

def user{}
def account {
    relation owner: user
    permission read = owner
}
definition creditcard {
   relation parent: account
   relation owner: user
   relation viewer: user

   permission read = owner + viewer + parent->read
   permission destroy = owner
}

definition virtualcard {
   relation parent: creditcard
   relation recipient: user
   relation viewer: user

   permission read = recipient + viewer + approver + parent->read
   permission spend = recipient
   permission requestupdate = recipient
}
