How an error is handled
When an error affects a published result, the affected function or figure is paused first, then the issue is reproduced, then the correction is verified against the source before anything is republished. Where a material change alters what a page previously told you, the change is explained rather than quietly applied.
Review dates mean review
A source review date is not renewed because a scheduled job ran. Rechecking that a URL still resolves does not confirm that the measurements on it are unchanged, and the two are not recorded as the same thing. A date printed on a page means someone opened the source and read it on that date.
What counts as a correction here
A dimension that does not match the page it was quoted from. A stated requirement attributed to the wrong party, such as a seller’s figure described as the maker’s. A calculation that does not reproduce from the figures shown. A record published on a source that should not have supported it. All four have happened on this site. In one case a product record was taken down entirely because its published width could not be traced to the page it was attributed to. In another, a single mis-paraphrased figure had reached two guides, a drawing and a trust page, and was corrected everywhere it appeared rather than only where it was first noticed.
What is not a correction
A maker changing its own published figure is not an error here. It is re-checked, the record carries the new figure and a new date, and the old one stops being quoted — recorded as a re-check rather than as a correction, because nothing was wrong when it was written. Nor is disagreement about which product is better a correction, since this site does not rank products or recommend one over another.
