The 2026 bundle was collected only after the contest closed on 2026-08-10, so no statement is mirrored while a contest is running.

One eleventh-edition entry (第三届 C4) has no full-text link and is recorded as missing. Statements are collected two ways. Eleven statements are PDFs from the CMS: 2015 (one combined paper), 2016, 2019 and 2020 A/B/C, plus the separately announced 2020 Nandu special problem. From 2021 the contest runs on the organiser's BdRace platform (www.tipdm.org:10010), whose public API serves each problem as rich text; 21 problems across eight editions of the challenge and skills tracks are snapshotted from it, but the platform cuts 20 of those bodies off with a row of dots or an invitation to fetch the rest from a WeChat account, so only the 2023 challenge A statement meets the complete-statement bar and reaches the library. 2017 and 2018 are absent entirely because those detail pages now redirect to the site root. Every data set is hosted on pan.baidu.com rather than an organiser domain, so none is mirrored."

Eight editions are collected, the fifth (2017) through the twelfth (2026) -- everything the current official site lists; earlier editions predate it. Award-winning papers are published as printed volumes and on CNKI, not on the site. The site serves plain HTTP only; its TLS port is closed, hence plain_http_only."
