Corrections ledger
A public record for material factual corrections. New entries distinguish content corrections from tool, dataset and method releases.

How to report a correction
Send the page URL, the statement at issue and a primary source to [email protected]. A correction is material when it changes a factual claim, a source, a measurement, a limitation or a published tool behavior.
What is in scope
The ledger covers factual changes that could affect a reader's technical decision: a misstated behavior, an obsolete source, an incorrect date, an error in a measurement, or a tool result whose public explanation changed. Small wording edits, grammar fixes and layout changes stay out of the ledger unless they alter meaning.
How entries are written
Each entry names the affected page or component, the date, and the nature of the change. When a source is involved, the corrected page should cite the source directly instead of forcing readers to infer it from this ledger.
The absence of an entry means no material correction has been recorded for the public site at this time. It does not mean that every external source is permanent, so readers should still use the cited primary links on the page they are checking.
Current ledger
| Date | Scope | Record |
|---|---|---|

Dataset and validator changes are recorded in the changelog. A page update date alone does not imply that a correction occurred.
