      We require that config.transactions and TransactionParticipant have consistent state after every command (or the session is invalidated) so that subsequent users of TransactionParticipant know whether the session needs to be reloaded from disk. We will always update config.transactions before updating the in-memory state in TransactionParticipant. If we throw an exception before updating the in-memory state, we must invalidate the session. Audit all abort, commit, and prepare codepaths to ensure they follow this pattern
