BREAKTHROUGH REVIEW

Breakthrough review

Submissions that exceed a published record enter the Pending queue first. Passing the arena verifier is only the first step; an entry moves to Verified only after source, metric convention, rounding precision, and construction checks are complete.

CLAIM POLICY

Certification standards

  1. 01Traceable external benchmarkThere must be a public source and an explicit comparison value. An internal baseline generated by this site does not count as an external record.
  2. 02Verified complete constructionThe complete answer is rescored by the submission verifier. Each certification snapshot is pinned to that exact score and contributor and does not transfer when the record changes hands.
  3. 03Rule out precision artefactsTruncated and rounded literature values are expanded to their most conservative interval, accounting for coordinate precision, solver tolerances, and reconstruction error. Last-digit tweaks within uncertainty bounds remain candidates; certification requires either a proof or a margin beyond all identified uncertainties.

Certifications permanently record historical achievements. For live standings, holding the current site #1 earns 1 point and a certified world #1 adds +3 points; an internal takeover removes both, while an external advance removes the world #1 bonus. Historical certifications do not stack points.

UNDER REVIEW

Numerical leads under review

These constructions pass the site verifier, but external sources, unpublished trailing digits, or error bounds still await manual review. Pending status adds no world #1 points; eligibility from earlier certifications is calculated separately.
