I have no dog in this fight, but simply claiming a count of tests get you anything is like saying your code coverage is 100% - it sounds really good until you think about what 5000 unreviewed tests actually... do.
If I go by the contributor numbers on Github, I see Claude has committed something on the order of 300,000 lines of code. I don't think it's reasonable to review that much code, even in weeks worth of time.
I haven’t needed to do such a thing in a while, but my “rule” for explaining how unreasonable is to say “if I only glanced at each line of code for 1 second, without bothering to understand the details, it would take me 3 and a half full 24hr days non stop to simply look at”. So it’s definitely more than 1 work week because presumably other stuff is going to need to get done in that time too. Actually understanding it is going to be at least a multiple of that, and probably the multiple is ~30x.
