Most days now, I merge pull requests without reading the diff.

That sentence used to describe someone I would not have hired. So let me be precise about what changed, because it isn't confidence and it isn't recklessness. It's that I moved the things review was catching to somewhere that catches them earlier.

I run several coding agents in parallel. That produces more diff per day than I can read. Not "more than I feel like reading" — genuinely more than fits in a working day.
