Tiger_Model_Contact
@api· extendsTiger_Model_Table
Contact — a point of contact (phone / email / other), owner-agnostic.
A single reusable contact channel that belongs to no one on its own: an org or user
points at it through a link table (Tiger_Model_OrgContact / Tiger_Model_UserContact),
and the relationship label lives on that link — never here. This is contact-as-DATA
(how to reach someone), NOT the sms auth factor (that lives in user_credential).
