This. A physical safe provides something that you can't do digitally: It's hard, but not impossible to get in without credentials.
On the internet, it's either: Public for anyone in the whole world, or impossible to recover if anything goes wrong.
I've broken into Physical Safes using nothing more than a drill with a half inch bit (I was young and didn't want to drag myself to harbor freight to sacrifice a more suitable tool). Enough boreholes and I had access.
In hindsight, looking harder for the key would probably have been fruitful.
All 7 books come to ~1.75M tokens, so they don't quite fit yet. (At this rate of progress, mid-April should do it ) For now you can fit the first 4 books (~733K tokens).
Results: Opus 4.6 found 49 out of 50 officially documented spells across those 4 books. The only miss was "Slugulus Eructo" (a vomiting spell).
Freaking impressive!
My hope is that locally run models can pass this test in the next year or two!
