Where it stands

  1. OpenedOct 21, 2026
  2. Exploring0 routes
  3. Computing0 jobs
  4. Verified0 routes passing
  5. Adopted0 merged

Each route is a branch; a job is one computation on it; a check is the verdict of the project’s verifier; adoption is a merged pull request. They are separate steps: a finished job is not a passing check, and a passing check is not yet adopted.

Placeholder. This problem is here so the problem panel can be tried out. Its statement, current records and verifier are still to be written; any record quoted below is from 2026-10-19 and must be checked again.

Problem

Long-tail open problems from erdosproblems.com and open implications between equational laws, worked on together with teorth/erdosproblems and teorth/equational_theories. A counterexample is a finite structure checked exactly; a proof is a Lean 4 file that compiles without sorry or new axioms. Each open statement is a sub-issue; the list is still to be chosen with those projects.
