Some questions about the lore

So I'm planning to join the Black Library's open submission, and I want to write a script about a tech-priest (Dominus or Manipulus) rise an automatan (maybe Thanatar Calix), but before I start, there's something I want to understand first:

  1. In Mechanicum's the Death of innocence, it saids "only a very few foundry can sense the danager and cut down the connection (with the Olympia)". My question is: can I forsee that there's actually a few automata foundries are safe? I mean, you can still call less than 10 foundries (including the main characters' in Mechanicum) over 10000+ as "very few", so...(⁠•⁠‿⁠•⁠)

  2. How does the servo-cannon from the new Guardsman's KT actually work?it's not AI for sure, but there's no tech-priest controlling that cannon, so...how (⁠ㆁ⁠ω⁠ㆁ⁠)

  3. We know that almost all Admech's tech-priest are insist on collect data (especially STC), but will they still do experiment related to technology?let's say "Oh, I find a STC to build a plasma gun, let's try if it can be bigger to plug into a Dunecrawler" is it possible (⁠ㆁ⁠ω⁠ㆁ⁠)?

I hope the lore-wise priesthood brothers could solve these questions, thanks (⁠・⁠∀⁠・⁠)
