	/// This test checks that a block that is valid from both a gossip and consensus perspective but that equivocates late is rejected when using `broadcast_validation=consensus_and_equivocation`.

	/// This test is unique in that we can't actually test the HTTP API directly, but instead have to hook into the `publish_blocks` code manually. This is in order to handle the late equivocation case.
