The only reason I could see for the mines was to force an enemy into a limited number of options if they wanted to capture the station.
Then again, a superdense minefield such as the one seen (with non-exploding mine types for proximity action) would indeed be a plausible response to the threat defined onscreen: that of invisible Klingon ships.
Defenses might exist against weapons launched from standoff ranges (considering nobody bothers to fire standoff weapons any longer!), but cloakship attacks are shown to be proximal, and the minefield would quite nicely protect this single installation from such.
The station was described as a forward operating base for S31. Can a FOB be a headquarters? I always believed FOB were outposts on the front lines with the headquarters being located further back.
This episode casts no doubt on that definition - we get no hint that Section 31 headquarters would have been compromised by these events, say. So it seems the four Admirals were lured into this location on some pretext, perhaps by Control itself, perhaps by the entity that had taken over Control via Airiam via the Probe via... whatever the origin.
Everybody else aboard would probably have to be dead, too, as if they were okay with the killing of the admirals, they would probably have taken care of that themselves, with more efficient means than locking out 90% of the base and suffocating them there. But if Control's orders are obeyed without question, perhaps most folks were ordered to go elsewhere? The station does have an apparent hangar box at the bottom, perhaps large enough to house one of those trademark spyships even; certainly there'd be capacity for sending folks on faux errands or evacuation.
Regarding "logic extremists," I would tend to think that's more a general characterization of those who espouse taking logic to the most extreme of conclusions and accordingly radical of actions—which seems apt for an admiral running an operation like Section 31—than a moniker specific to a particular terrorist sect, or supremacist/secessionist political party, or other organized group. It's probably roughly equivalent to "religious fundamentalist"—logic being very much akin to a religion among Vulcans.
Indeed. And even if logic extremists are actually a more narrowly defined political party, all the arguments about diversity within that group would still hold. The party might officially promote action but just as officially denounce those who practice specific sorts of action. OTOH, even people in leadership positions in the military would be unlikely to be able to actually pursue a political agenda there...
