Helped: Model being more critical in analysis.
I just used Sonnet 4 to analyze our quite big mono repo for additional test cases, and I feel the output is much more useful than 3.7. It's more critical overall, which is highly appreciated as I often had to threaten 3.7 into not being too kind to me.
