See PHI1419. In Applications → (Pick Something), if an application policy is set to "Custom Policy", the policy is not linked. This should be linked to a policy dialog.
See downstream https://phabricator.wikimedia.org/T231734. Currently, if you can not view an object, we may disclose an abnormal amount of information about certain policies, including "Members of Projects: ..." policies. Instead, this form of the dialog (where you do not have permission to view the object) should be less revealing so that it does not leak information like Members of projects: Security, File Uploads, SVG File Handling.
See downstream https://phabricator.wikimedia.org/T211498. Probably mostly see also T6802. This is the opposite case: when you can view an object, the policy dialog is not very helpful about explaining custom policies. At a minimum, they should be linked; better would for them to be inlined.
See T8808, which is probably adjacent and trivial.
