+/**
+ * Tests backwards compatibility support from Helium-1 to Helium.
+ *
+ * In Helium-1, the 3-phase commit support was moved from the ThreePhaseCommitCohort actor to the
+ * Shard. As a consequence, a new transactionId field was added to the CanCommitTransaction,
+ * CommitTransaction and AbortTransaction messages. With a base Helium version node, these messages
+ * would be sans transactionId so this test verifies the Shard handles that properly.
