Show Content Security Policy at app startup

I am trying to setup the CSP and Ember is doing something funny, difficult to describe what. I am rightly configuring one part, and it is failing in another part. Or suddenly, livereload is blocked. Or it says that script-src is not defined, and falls back to default-src, which is fine, if it weren't a lie. I know ember-cli-content-security-policy is processing the CSP to allow for livereload and whatnot, but I do not know when/how this is done. I want to verify that the CSP I configure is surviving ember-cli processing, because after one hour of debugging I do not trust it anymore.

Long story short: I want to see the CSP at startup of my app, right when the versions are shown. I do not want to see the CSP that I have configured, but the one that Ember is using, which might or might not be the same: this is exactly what I want to find out.

How can I tell Ember "show me the CSP that you are using"?
