Phaenna... Only two red alerts? No ARM red alert missions?

You all talking about waiting for upgrades but we're already on the 6th one...

I could be wrong but having done Ardorum as soon as it released, no, there was only meteors v1, spores v1, and possibly astromagnetic v1 at first (but unsure if it was very early steps or just at release for that one). Never had 4 of them.

There were 4; you just got unlucky. Both variants of Sporing Mist RAs were available from the start.

Sinus Ardorum's first zone expansion (which introduced the 5th RA variant) didn't happen until stage 8 on the infrastructure index, and the second (which introduced the 6th RA variant) wasn't until stage 14. I assume it will be similar with Phaenna, just that the number of available RAs will probably be 2/4/6 instead of Sinus Ardorum's 4/5/6.
