For as long as we are around, Montioch will never enter Invasion! It goes quite a bit beyond simply guarding HR 2204; take a look at the systems nearby:
That entire group of systems nearby is marked for eviction, which will guard Montioch itself as well as freeing from attack HR 2204, HIP 29596, Muruidooges, Vogulu, Bi Dhorora—and Omumba, as it happens! I had not considered restoring all inhabited systems specifically, but that
would follow as a result of a sensible continuation; HIP 29226 is the main bridge system above, which cannot be helped because HIP 30439 has a Matrix (and indeed has over 100000 strength), but Col 285 Sector PM-B b14-0 above leads up to HIP 30502 and Vasupari, all quite Matrix-free and can be cleared gradually without any Alerts fighting back.
Operation Redacted established that Titans are dormant, we used that information to make a M. Leigong district, and just as soon as we finished there a Col 285 Sector VN-Z b14-0 was cleared over at M. Hadad! The 10000 for keeping HIP 29226 clear is a bit more steep, but there are many more systems on our side of that bridge, and I think we have a real opportunity to carve a wide arc of space.
