Access to child page but not parent

[DrQuincy]

I just wanted to check this is okay before I roll it out. I'm pretty sure it is but I wanted to be sure.

Let's say you have:

• Parent page [template=parent]
  • Child page [template=child]

In the back end site tree if I want Child page to be viewable and editable by the current user but I don't want Parent page to show in the site tree. If I remove all view permissions for template=parent but allow for template=child, will they still be able to view Child page and edit it (if I supply them with the direct link)? 

I stupidly asked AI this question and it's adamant permissions are inherited regardless so if you can't view a parent there's no way at all to view the child. 🤔
