NAVIGATED You were force-navigated here
from a page served with Content-Security-Policy: sandbox.
This is the canonical URL from that page's <link rel="canonical">.
In the real threat model it is an attacker-controlled destination. The sandbox
directive should have prevented the source page from navigating the top frame,
but De-AMP performed the redirect without consulting CSP.
/de-amp/csp-sandbox/sandbox-amp, served with
Content-Security-Policy: sandbox and AMP markup.
