Theorem · version 2
There exists such that for every N there are n ≥ N and a set of n distinct Euclidean planar points with at least unordered unit-distance pairs.
An asymptotic construction, not a statement about every size or an explicit value of δ.

Complete formal proof reported externally
The finite-set definition counts ordered off-diagonal distance-one pairs and divides by two. The formal theorem uses EuclideanSpace ℝ (Fin 2), not the product sup norm, and proves arbitrarily large sizes. It does not specify δ = 0.014.

The manuscript credits an internal OpenAI model with the original argument; subsequent human editing and external mathematical checking are separate roles.
The companion paper provides a human-digested argument and background for the exponent gain, including the classical upper bound.
