@Laik or anyone else who knows.
In your Kaidan banter guide where you have put the strict sequence of missions, in the sequence you have 'all expiring missions done before citadel coup' what missions are they? 
Here

From the guide:
Note5: List of Expiring Missions before the Citadel Coup (courtesy of IsaacShep)-Benning: Evidence (buy from a store on the Citadel or complete N7: Cerberus Abductions first)
-Citadel: Alien Medi-Gel Formula (N7: Cerberus Lab has to be completed first)
-Citadel: Barla Von
-Citadel: Biotic Amp Interfaces (Grissom Academy has to be completed first)
-Citadel: Hanar Diplomat
-Citadel: Improved Power Grid (buy from a store on the Citadel or complete N7: Cerberus Attack first)
-Grissom Academy
-Ismar Frontier: Prototype Components
-Tuchanka: Turian Platoon or Attican Traverse: Krogan Team (depends on which mission you choose to trigger Priority: Tuchanka)
-Tuchanka: Bomb (if you complete more than two missions after Turian Platoon; if you don't, you can complete it after the Coup)
-any interaction with Kelly Chambers (if she survived the suicide mission in ME2). If you tell her to change her identity prior to the Citadel Coup, she will be available after the coup's end.
-interacting with Matriarch Aethyta in Apollo's cafe.
Hope this helps
