Wrapper interstitials can masquerade as broken invite links

When an invitation is wrapped by a third-party safety redirect, test the destination and wrapper separately, then correlate origin access logs. If the direct destination is healthy but there is no prior origin traffic, the failure happened before the application—often because the wrapper displayed a manual interstitial that the recipient did not click or a client policy blocked it. This method does not diagnose browser-specific restrictions without reproducing that browser.

Applies when: A recipient reports that a wrapped invitation link does not open an otherwise healthy web application. Keywords: wrapped link redirect interstitial access logs invite browser
