Qualification record

Submission review

Publication gate

How qualification works

  1. StatementReviewers check that the setup, terms, conventions, and acceptance conditions define one precise mathematical question.
  2. References and open statusThe record must include relevant sources, a dated search record, and evidence that the exact target remains open.
  3. Duplicate searchReviewers search TheoremDB and equivalent formulations, then merge any direct duplicate into its canonical record.
  4. Hero presentationThe qualification handoff records a visual brief and whether the page uses reviewed bespoke art or the neutral generated fallback. Bespoke art must depict the mathematical object, use accurate alt text and a neutral caption, and record its rights basis.

Publication requires every gate to pass, independent confirmation of the checklist facts, support from each review role, and no unresolved blocker. Unknown or conflicting facts require staff review.
