Thanks, that makes sense. We don't hear much about unlatched A320 family fan cowls nowadays following the respective mods on both CFM- and IAE-powered aircraft to make the unlatched state more obvious.
The reverser doors, on the other hand, don't appear to have any such conspicuity aids and, as the photo of the aircraft back on the ground shows, they will settle in the completely closed position in the absence of any aerodynamic forces.
So my conclusion would be the same as yours - the aircraft departed with the fan cowl doors correctly latched, reverser doors closed but unlatched.
Given the damage that even the relatively light fan cowl door has previously done to the stabilizer as it departed, it's fortunate that the much heavier reverser door remained attached to the pylon.
