Erdős Problem #319 remains OPEN. Statement: What is the size of the largest $A\subseteq\{1, \dots, N\}$ such that there is a function $\delta : A \to \{-1, 1\}$ such that $$ \sum_{n\in A} \frac{\delta n}{n} = 0 $$ and $$ \sum_{n\in A'}\frac{\delta n}{n} \neq 0 $$ for all non-empty $A'\subsetneq A$. Topics: number theory, unit fractions. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: possible.

vpr_84e3d3e66829514dfinding.noteSEMANTIC-EDGE DRAFT -> Erdos #317 (vf_68df117a797f45cf) [related, confidence 0.6]: Both concern signed sums of reciprocals (delta_k in {-1,0,1} or {-1,1}) approximating/avoiding values; 319 asks for the largest such set while 317 asks for a uniform smallness constant, sharing the signed-reciprocal framework. -- LLM-drafted (20-agent extraction, 2026-06); NOT adjudicated. Accept or reject via `vela proposals accept/reject` under reviewer authority.
