To be honest, this release has surprised me with its quality. I've taken a moment to play through it a couple weeks back and I genuinely enjoyed it. Now, it's time for some sort of feedback, even if a very late one.
From the gameplay standpoint, most things are really solid. You've got decent writing going, both missions are paced pretty well, and aren't exceedingly difficult. They technically seem to be tied together pretty well. Beyond that, I haven't encountered any major bugs preventing me from progressing. I've enjoyed playing this.
Also you have brought in a couple of pretty novel, if rather minor, design decisions: using the perspective of two separate pilots and needing to scan the enemy destroyer's subsystems before commencing another destroyer to engage. These I haven't seen used in the community much and they work pretty well here. Although in your future campaigns please use these sparingly, they won't bring much positive quality if overused.
There's still a couple things you might like to polish up in the missions to make them as good as they can be. In the first mission, I have also experienced an issue with debriefing - I got both the positive outcome and AWOL debriefings after landing on the Cyrene. I believe it might be related to the "Protect Alba" directive that never actually becomes complete. Also, in my experience, the defense of the Alba gets a bit tough near the end, as the amount of enemies incoming at the same time increases about that time, but it's manageable.
In the second mission, I've noticed that the player craft is invulnerable since the start, which would be a really quick fix to do. Also, given how massive of a threat are the Orion's beams, I think the mission should tell the player to strike the beam cannons on Psamtik's side as soon as the scanning is done. I nearly lost the destroyer before I've noticed just how much damage can the Orion put out in a short period of time.
Also a word of comfort: while I'm not versed in the GitHub situation, remember that this community doesn't ban people just because some might find them annoying, or for poor quality mods, or for anything that isn't really harmful to anyone. If it did, I would have been kicked off months ago.

I may have a tiny suggestion too, actually: you could try using a
single, about one second long fade-out to black when the player is landing on the Cyrene in the first mission. While it's a purely cosmetic thing, I think it could make the ending of this mission one tiny bit smoother and easier on players' eyes.
That said, carry on and good luck! I'm interested in seeing more campaigns like these.
