I'm… surprised your draft proposal is, at the very least, neat-looking. Dry science tone is nice. I'm not in the right mind to give an in-depth critique, or, god save, Live2Die, but I think your Usage is more Special Containment Procedures than actual instructions for the object. Slap a couple of test experiments the CI wants done on the Engine on the Usage portion. Expand on Victor Strate's concept with more physics theorems, or add something else to the object for that.
Next, remove these words:
"All excess electric power is to be stored in specially designated batteries": Focused too much on a trivial matter. Remove.
"Only Sigma or Delta class personnel may enter the device": Just a bit of lore correction. Sigma only.
"nigh indestructable": Chamber cannot be damaged, or something like that would be better.
"and are to leave all personal effects outside the cell:" Another trivial thing. Remove that.
"drawer that fills with an unidentified blue powder." that is filled with… dunno, find something neat to describe the powder. Unidentified powder, without the color, can work… I guess.
"Physics Engine version 7.0! The latest model by Farrell and Son. Energy Co! Bringing the future to us! ( Mac model)" No. I've seen many strange objects being hand-waved as simply 'strange for us, normal for alternate / anomalous people' appliances. They usually don't add anything to the article anymore. Replace with something dry, like a Windows XP reboot / set-up<idk> text.
I can see you're still writing, so I will update as you ask.
