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

Given a target plasma boundary, find closed coil curves, a few dozen Fourier coefficients each, whose Biot–Savart field is tangent to the boundary while length, curvature and coil spacing stay buildable. Scoring follows Princeton’s SIMSOPT and the ConStellaration benchmark; the target and the weights are still to be fixed.
