The J stands for Jacobian, ref Jacobian Matrix, Jacobian "Lens"

>ok so everything except this message is "vibe coded". when reading the anthropic paper, i had a few ideas about behaviors of this "jspace" i was curious about. i asked fable to brainstorm with me and also let it suggest more experiments that would be interesting. then i let it run experiments autonomously (almost) on our cluster. i'm not an expert in this domain and the experiment design as well as my ideas probably don't make total sense for someone who is.

How can anyone trust anything at all here?
