You really should've included Rough Beasts of Empire and Zero Sum Game (in that order) in your DS9-R reading list, because they're officially part of that series despite being published under the Typhon Pact miniseries header.
"Officially" is putting it too strongly, especially since, IIRC, the author of RBoE has said he doesn't consider it a DS9 novel (only 1/3 of it deals with Sisko, the rest with Spock and the Romulans). It would be more meaningful to say that both books contribute materially to the ongoing DS9 continuity.
ZSG includes the 'The saga of Deep Space Nine will continue' tag on its final page, which, as far as I am aware, is only attached to novels which are officially part of the DS9-R's primary core continuity. RBoE's place could be argued, but I personally consider it to be an official part of the DS9-R core continuity, and based my statement on that.
