Corrections
When a number here changed
Every entry below is a time a published measurement on this site was replaced, and the reason it was replaced.
This log is not maintained by hand, which is the only reason it is worth reading. There is no code path in this product that edits a stored score. A correction is always a new analysis recorded alongside the old one, so this page is a direct read of what actually happened rather than a summary somebody remembered to write. A change we forgot to disclose is not possible; a change we failed to explain well is.
No analysis has been revised yet. This page will fill itself.
What counts as a correction
Two things, and they are different. A re-score happens when we change how the analysis works: the version is bumped and the affected archive is measured again, so a quality improvement is comparable across old and new articles instead of being a silent shift mid-corpus. A fix happens when one article was read wrong. Both appear here, and the reason says which.
Errors in civic reference data — a wrong helpline, an outdated officeholder — are corrected through a different route, because those are facts rather than measurements. Report one here.
