Compare a fixed list of ten security-relevant response headers across two releas
Compare a fixed list of ten security-relevant response headers across two releases and name the specific reverts. Reports a header removed, added or changed, and separately a reduced Strict-Transport-Security max-age, dropped includeSubDomains, a newly permitted unsafe-inline or unsafe-eval, and a Content-Security-Policy that moved from enforcing to report-only so it no longer blocks anything. Observable differences only, not an assessment of whether either configuration is adequate.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
