Kappa is used as the condition number in most of the article, except in the section "The Resisting Oracle", where kappa is used for a parameter which appears to not be the condition number of a matrix in this article (rather a limiting value).

This might be oddly specific and nitpicky, but as I read that section, I saw this

which prompted me to assume $\kappa$ is the condition number of $f^n$, before noticing the kappa buried in this (which I am reading a little less closely due to it being a natural analogue of the prior example)

Especially since, in that last term, the important part is the $| w |^2$ while $\kappa$ is (presumably?) an arbitrary parameter.

This could easily be fixed by using a different letter to indicate novelty, or by saying "where $\kappa$ is a fixed constant not depending on $n$."

I was on the fence about this. I think this bug report is enough to push me over the edge to using kappa bar instead. Thanks!
