Corrections

Every number has a source. Each card names the file it comes from and its as-of date. Numbers are shown as the source disclosed them.

Checked before publishing. Each night's data is checked before the site is rebuilt. A fund scheme whose file fails a check (weights that do not add up, impossible quantities, a wrong ISIN) is held back from every page until it passes; the status page lists each one with the reason. If a check fails for a whole data set, nothing is published and the previous day's site stays up.

Report a wrong number. Every card has a "Report a wrong number" link, which opens an email to hello@fund-tracker-aax.pages.dev with the page named. Say which figure looks wrong and, if you can, where you saw the right one.

What happens next. The figure is checked against the source file. If our reading was wrong, the parser is fixed, the stored months are read again from the source and the corrected pages go live with the next nightly build. If the source itself is wrong, the figure stays as disclosed and the case is noted on the status page. Corrections are made in place; the source file and its date stay on the card.
