1 In Stellaris 4.0 gestalts can produces trade so Commercial Spire should be allowed to gestalts. 2 Corporate having additional bonus with Commercial Spire could be replaced by Corporate having access to Commercial Spire level 2.

1. The dot folder is generated by IDEA which I use for coding, it is unnecessary to delete
2. There will be an new ground megastructure being an upgrade of Great Temple (temp name, an alternative of heaven colossal for spiritualists)
3. I don't think gestalt having business is a good idea, instead I added Logistics Centre for gestalts to produce trade
4. I just added Universal Finance Multi-Area as upgrade of commercial spire, but yes it could be limited to corporations only

Thank you for correcting my misnumbering. For 3: In Stellaris 4.0.6 the trade building for gestalts is named Logistics Hub so the name Logistics Centre fit. The 2 only issues I can think about are first that making a separate megastructure give you more work and second that if the planet change owner from individualistic to gestalt or reverse without conversion mechanism then the megastructure is useless for the new owner.

2 Actually the Administration Axis is too powefull for a level 1 mega in my opinion. 5 I suggest to look at bonus on job output, for balance and consistency. Maybe Heaven Colossal from +0 to +2, Mining Pivot from +3.5 to +3, Advanced Forge from +3 to +2, War Headquarter from +0 to +2.

2 Thank you for taking into account my suggestion. In d_heaven_colossal you can: replace planet_entertainers_unity_produces_add by planet_jobs_unity_produces_add so it affect bureaucrats in addition to entertainers; replace 2 by @plnmg_unity_add so it use mod constant.
