Didn't read through everything or have the ability to playtest, but everything I am seeing looks super cool.
I also am a massive fan of d100 systems and degrees of success and failure, so I might be a bit biased, and the whole theme seems to be a weird mix of mech's and magic which has a lot of potential to have really interesting world building stuff going on/ and or it is taking inspiration from WH40K and the "magic" is just lost tech.
Either way, I like what you have.
