class PactBroker::Matrix::PactNotVerifiedByRequiredProviderVersion
The pact for the required consumer verison has been verified by the provider, but not by the required provider version (this row is not included in the matrix, and it's absence must be inferred) Update: because the left outer join now returns a row with blank verification details, this scenario is now indistingishable from PactNotEverVerifiedByProvider
TODO: merge these two classes when it's verified that they are duplicates.
