 // e.g. a certificate for google.com that chains up to a root CA not expected by
 // Chrome for that origin, such as DigiNotar (compromised in July 2011), or
 // other pinning errors such as a blacklisted cert in the chain, or
 // (when opted in) other certificate validation errors like an expired
 // cert. The report from the user will include the hostname being accessed,
 // the full certificate chain (in PEM format), and the
 // timestamp of when the client tried to access the site. A response is
 // generated by the frontend and logged, including validation and error checking
 // done on the client's input data.
