What the check does, and where it stops.
Why it matters
One insecure script on a secure page undoes the security of the whole page.
What a failure looks like
A failure is a finding in your result. The check is scored, so it can lower your score, and the Full Report gives every finding its severity and a fix. If the check cannot finish, it is recorded as unknown: it carries no penalty, and it is never a pass.
Where its limits are
Cannot see what a page adds later with JavaScript.
ReliabilityModerate: confirm before acting
