Verification results are attached to the pact content (the versioning of which is managed by the Pact Broker) rather than to a pact with a particular pacticipant version number. This means that if a pact is published with the same content as a previous one, it inherits the same verification results, and is hence "pre-verified". You can read more about this here: https://docs.pact.io/getting_started/versioning_in_the_pact_broker
