Suppose $n$ points in $\mathbb{R}^2$ determine a convex polygon and the set of distances between them is $\{u_1,\ldots,u_t\}$ . Suppose $u_i$ appears as the distance between $f(u_i)$ many pairs of points. Then $\sum_i f(u_i)^2 \ll n^3.$

For every finite planar point set P, the sum over its distinct determined distances of the unordered-pair distance multiplicities equals P.card.choose 2

Decision performer: Accept the exact current Erdős 94 assertion in the compact v3 lineage after independent scoped checks of occurrence mapping and correction scope. Preserve the correction and all nonclaims without changing the scientific assertion.
Result performer: This proves only the elementary sum_multiplicity identity, not the cubic Erdős 94 theorem or either other variant.
