Events and comparison sources

An event counts once when any of its official reports enters the collection. Each provider is counted separately. Later backfills preserve the month-end score.

Figures cover the sampled events only, compared with independent publications at the end of each month (UTC).

Available archives vary by source. Changes to undated documentation pages are reviewed before they may appear in the feed.

Primary sources feed the editorial selection. Baidu, Naver and Yandex remain available by filter and in search.

The method

Facts. With context.

  1. Collect

    Critical sources are checked hourly; all sources are checked nightly. One record keeps the original title, published date and sources for each event. Undated documentation changes are held for review. The French and English RSS feeds support WebSub to notify compatible subscribers after publication.

  2. Classify

    A yellow square marks a change that may affect a TSEP check, access rule, diagnosis or deadline. Recurring publications and events remain background information. A yellow triangle identifies background news; a dashed circle means classification is pending. Translations are editorial.

  3. Review for TSEP

    Each month, the review connects announcements to relevant TSEP controls. For each item reviewed, the team decides whether the protocol already covers it, a change needs consideration, or monitoring should continue or close.

Impact explains practical consequences after human review in the displayed language. View adds a distinct editorial position: it is public only after personal approval, with the author’s name and reviewed language. AI-assisted proposals remain in the private workspace.
