Feantari: The PoH rewrite should be fine. If it breaks down in play we might have to modify it, but I'm not seeing anything too significant at the onset.
Reaver: Regarding the lightning on a chain: First of all, the artifact needs a repair rating, so say 2. Secondly, you annotated that it needs repair every 6 turns. If you mean ticks, that means it's a fire and forget weapon, but I'm not sure that's where you were going. If you do want a f-a-f weapon, I'd recommend you change attunement to something trivial, 1m, and have a per use cost of 3m(per action, not per attack). Gives you a +5L damage strike, rate 4, that's unblockable without the use of charms. Magitech being magical, they wouldn't completely short out on a single hit. But if each time it hits a magical device it causes one increment of use, then you wind up with an ablative magitech killer. But it isn't terribly effective as a weapon, due to that f-a-f problem. That puts it on the two dot level. (Pro: Unblockable, grinds apart magitech, damage and rate on par with a Reaper Diaklave, less attunement cost, con: one flurry and you're done.)
Or did you mean 6 scenes of use requires repair? Then it becomes a thoroughly competent combat weapon, pushing the rating up to 3. That also falls in line with the suggested attunement cost and artifact level. The Magitech killing ability would remain as above.
Regarding AICA: What mechanical effects do you want her to have? In general, if she has human sentience and attributes, she's a base artifact level 2 with superior durability, magical material construction, and loyalty counterbalancing the increased repair rating. Beyond that, if you want her to have the effects of a Charm, Say Craftsman Needs No Tools, she gets bumped to level three, and possibly level four depending on what charms, how many of them, and what her essence requirements are. For artifact level five, she could have the passive effects of CNNT, Words as Workshop Method, and count as two supernatural aids, giving a bonus of an automatic success but counting against maxima. However she would require a Level 2 hearthstone of which no other effect is given and 1 mote per day, OR twenty motes per day. That would also giver her stats on par with an Exalt, and a repair rating of four. You'd also need to know those charms, so it makes a difference when you're picking what you learn.
Now as to fitting her into the game, that is absolutely no problem. In general I like PC allies and encourage you to put her to work doing the things you aren't going to want to roleplay yourself. (If you guys want to do some B&E, put her on watch or something similar, as well as her intended function as a crafting aid.)
gather818: The sheet looked fine, but it's gone now. Do technomancy and make it live again.
Other people: For those of you who expressed interest but have posted no characters, please do. There's still plenty of room.
