Okay, i hate arguing already, and i'll promise i'll be more clear next time.
But this
After checking that the circuitry of her Hand of Glory - actually just the paw of some roadkill, modern electronics make human ingredients obsolete - and checking the code on her Infrared-camera (decayed as usual) and the containment of a aluminum-silver dodecahedron, Jennifer grabs a taser and a raincoat and waits for the next bus.
is where i mention her doing the preparations.
To explain my intent there:
Magic in Shadowrun isn't tied to specific invocations, gestures etc. - those are pretty much based off the users own idea how magic works. That's why we have all those different magical traditions.
Jennifers magic is based around the idea that doing the right kind of calculation will allow you to access other dimensions. And electronics are very good at doing calculations, so she makes heavy use of them.
So to her, all she's doing is checking circuitry she's already prepared - for some reason that she can't yet fully explain off (in-character), the circuitry doesn't work properly if she doesn't do that.
Out-of-character, that's because the lynchpin doesn't matter as long as it's non-living (and not an active focus or such). You could take a pebble and smear some finger paint on it and it would work just as well as Jennifers carefully crafted nanocircuitry. Nor does the Lynchpin get destroyed, and it works just as well on artificial items than on natural ones because you're just anchoring a spell to it, instead of actually enchanting the object.
Hence, "checking on" means "prepare Alchemical Preparation" - again, i am sorry for not making this more clear in the IC-post.
I promise i will make it more clear when she is preparing Alchemical preparations. For now, i'd like to ask you to let her keep them, because they represent most of her active abilities.
