What we got wrong
We check other people's numbers, so ours had better be right. When they are not, this page says so — what the mistake was, when we found it, and what we changed. Nothing gets quietly edited away.
Two things we promise. We fix an error as soon as we know about it, and we leave the record of it here rather than pretending the page always read this way. If a mistake changed what a reader would conclude, we say that too.
Corrections so far
None yet — and that is a statement about how new this is, not about how careful we are. The first deep-dive went up in August 2026. A piece has to have been standing a while before a correction to it means anything.
When there is something here, it will say what the mistake was, when we found it, and what changed. Nothing gets quietly edited away.
