special rare techs prerequisites ?

[AlknicTeos]

I'm playing a pretty nomal 2.2.3. game, but with no starting gateways, but L-gates. And then there is

Spoiler

    modifier = {
            factor = 0
            NOR = {
                OR = {
                    has_seen_any_bypass = gateway
                    has_seen_any_bypass = lgate
                }
                any_relation = {
                    is_country_type = default
                    has_communications = ROOT
                    has_technology = tech_gateway_activation
                }
            }
        }

from tech_gateway_activation. and in the last 60 years ( ~ 2400 now ) or so the tech never came, I have already quite high physics repeatable techs, but no gateways yet.

Also what are the prerequisites for nanite world transformation ?
there is in the transform pre :

Spoiler

terraform_link = {
    from = pc_gray_goo
                                                                to = pc_continental
    condition = { has_technology = "tech_climate_restoration" }
    energy = 1000
    duration = 360
    potential = { from = { has_modifier = terraforming_candidate } }
    effect = { from = { remove_modifier = terraforming_candidate } }
}

how will those nanite worlds gain the terraforming_candidate?

edit : ah, I've read somewhere else that only grey tempest outcome brings colonizeable planets .... I guess I will change this

Gateway technology requires knowing an existing disabled gateway somewhere. Lgates dont trigger it.
As for nanite worlds, they only become terraformable based on an event with the lgates. Its completely random so sometimes you just wont be able to terraforn them.
