How this site is built
How this site is built, the rules it checks automatically every time it is published, and what it leaves out on purpose.

Rules checked every time the site is published
- Every number is stored once. Each number lives in one list, with its source and how it was checked, and pages refer to it there. A number typed straight into a page stops the site from publishing. This keeps the numbers the same in every version of a page. The timeline is the one exception: an event records what was true on one day, so its numbers are not updated later.
- Only public entries are listed. Each entry is marked public or not, and an entry that is not public must say why. Entries that are not public never appear in a list, a feed, or a search engine's map of the site.
- Every date has a source. Each timeline event comes from a dated record kept at the time, and an event without one is not shown.
- Links show when they were last checked. Links to other sites break over time, so each one carries the date it was last confirmed to work.
- A broken entry stops publishing. If any entry fails these checks, the site does not update until it is fixed, so no entry is dropped without notice.
Versions for different readers
Some entries come in more than one version: one for anyone, one for practitioners, one for specialists. Switching versions changes the wording, the background assumed, and how much notation appears. It never changes a number, a date, a source, a limitation, or how strong the claim is, and the site checks that automatically.
- Plain version
- What was asked, what came back, and why it matters, in everyday words, with a concrete picture where there is one. Any technical term is explained the first time it appears. Written for someone who has never studied the topic.
- Applied version
- Starts from the reader’s own field and says where the comparison stops. Leads with how the work was done and what it took: what was run, on what, for how long, what went wrong, and which parts could be reused elsewhere. No proofs.
- Technical version
- Definitions, notation, the exact statement, the method, the earlier best results and what improved on them. Assumes the reader knows the field. No analogies. The other versions are written from this one.
What is not public yet
38 entries are not public yet: either not on the site at all, or reachable only by direct link and left out of every list and feed.
They are counted here but not named, because for some of them even a title could say more than a venue's rules allow. The rule is on the publishing policy page.
What this site does not have
No comments, reactions, view counters, newsletter pop-ups, share buttons or citation counts. Every page works without JavaScript; search, version switching and link previews are extras on top.
