             id: 3
           phid: PHID-PLCY-e4v2fnbyuibi4supl5tn
          rules: [{"action":"allow","rule":"PhabricatorPolicyRuleAdministrators","value":null},{"action":"allow","rule":"PhabricatorPolicyRuleProjects","value":["PHID-PROJ-cwovm5gn2ilubjehcdgd"]},{"action":"allow","rule":"PhabricatorPolicyRuleLunarPhase","value":"new"}]
