 * Reports SSL assertions whose source, property, comparison or boolean target the

 *
 * Assertions written as plain object literals bypass SslAssertionBuilder and are
 * type-legal, because the fields are declared as plain strings. The backend rejects an
 * unknown source, an unknown property or an operator not allowed for the property with
 * a 400; a boolean or numeric property whose target is not of that type is accepted at
 * deploy but never matches at evaluation, so it is reported too.
