Source assessment
Proved
Analytic tenfold theorem reported complete in Lean
The project records a Lean build on 9 September and a Comparator replay on 12 September. These are external reports, not OpenMath executions.

Formal declaration
Analytic tenfold Schiffer and Pompeiu counterexample
Scope
An analytic tenfold counterexample
Research activity
Compare the two evidence routes
The analytic witness has frozen numerical input data and a certificate; the bifurcation construction has a separate C² formal theorem.
Neither external project has been executed by OpenMath.
History
The analytic certificate receives a public Lean replay
Question
Schiffer and Pompeiu conjectures

The full statement includes real-analytic Jordan boundary, tenfold dihedral symmetry, the published frequency interval, a real analytic classical Schiffer field and Pompeiu failure. The formal proof checks its own coarser exact numerical bounds using the same dyadic centre as the interval certificate.
