Bound findings

Erdős Problem #321 remains OPEN. Statement: Let $R(N)$ be the size of the largest $A\subseteq\{1, ..., N\}$ such that all sums $\sum_{n\in S} \frac{1}{n}$ are distinct for $S\subseteq A$. What is $R(N)$? Topics: number theory, unit fractions. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: A384927, A391592.

SEMANTIC-EDGE DRAFT -> Erdos #319 (vf_d3d947902c6331cb) [related, confidence 0.55]: Both ask for the largest A in {1,...,N} with a distinctness/signed-sum condition on subset reciprocal sums, the same extremal subset-sum-of-reciprocals setup. -- LLM-drafted (20-agent extraction, 2026-06); NOT adjudicated. Accept or reject via `vela proposals accept/reject` under reviewer authority.
