Every database on this site says it is checked and refreshed on a schedule. This page is the receipt: the 105 records verified against their organisers' own pages, or newly added, in the 30 days to 6 Aug 2026. A record only earns a verified date when the deadline or submission window we list literally appears on the organiser's page that day. Records we cannot confirm keep a "to confirm" note instead; nothing is guessed at.
A deterministic script fetches each record's cited source page and requires the listed deadline or submission window to appear on it, character for character, before the record gets a verified date. When a page shows a different date, the record is corrected to match the page. When a URL dies, the record is flagged for human review rather than silently dropped. The provenance notes for each dataset live in the repository beside the data.
