Since IIRC dauntless dosent make tinker, it likely isnt one. Tinker rating seems exclusively for advanced technology, other powers that create stuff may get sorted elsewhere.
Agreed. My thoughts here are that, since ratings are given based on posed problems, and common threads in solutions, (generally at least, I've always felt that characters in Worm have a bad habit of conflating the ratings as threats that are posed and the ratings as underlying mechanics) I'd argue that Tinker as a core rating isn't just about the tech and versatile empowerment aspect, it's also about the logistical issues Tinkers face.
You cut of a Tinker's supply chain, you hurt them in the middle and long run as their ability to build new devices and maintain their existing tech fades. Thus we might say that calling someone a Tinker implies not only that they're going to self empower and pull out bullshit, but also that their ability to pull out all those toys is somewhat dependent upon their supply lines.
Contrast your self-empowering Trumps like Eidolon, Grue, Glaistig Uaine, and Dauntless on the other hand, who have that same massive versatility, but lack the supply line issues. Two out of those four get more powerful over time and need resources to do so, (capes and
time, respectively) but you can't really take power
away from either of them like you can via damaging a Tinker's workshop. At least, not easily. Everything they have they can keep on their own bodies and once they have the resources in question, that's more or less
it.

On a separate line of thought, I'll note that ratings don't seem to have a hard cap at 12. It's been a
while but, IIRC, it's stated somewhere in canon or WoG that Sleeper is a Stranger 14 and I also recall WoG to the generally effect of what I'm saying. (Do you own research before quoting me though, it's been a bit.)
My
personal interpretation of the matter would be that every five ratings or so denotes the scale on which a character naturally operates (with some ability to move up in scale of operations from that baseline with time, favorable situation, or effort) plus some granularity between them. My intuition says that 1-5 would be near-normal human and street level stuff; 6-9 would be street/city-district, going on city/region; 10-15 would be city/region going on country/continent; and so on. So in this framework, endbringers are generally ~10 rated because they play merry havoc with a city or immediate region casually and can mess with a whole country or continent if circumstances go well for them and poorly for everyone else. (except Khonsu of course, but movers in general don't perfectly fit within this framework)

All that said, I'l like to make the motion that Sabrina's rating is a dual Shaker/Trump. Shaker for the 100m core effect range, Trump for the self-empowerment over time (including the ability to better self-empower as gaining more and more grief allows for more versatile and exotic effects.) No solid number because that
too increases as she gains more and more grief. (At any given moment there's a solid number but, well, it grows as more and more power the more she uses her powers causes her to bootstrap hilariously.) And the slash for dual rating because both sides of that are very deeply linked.
