Two instrument series show no positive serial wait correlation for PSR J0537-6910

We test a published no-positive serial waiting-time correlation prediction with PSR J0537-6910 glitch dates. Separate RXTE and NICER series give Spearman values of -0.048 and -0.146, with positive-tail permutation probabilities of 0.563 and 0.672. The 2264-day gap is excluded. All 23 NICER epochs and quoted bounds match the source table. A later-only series gives no clear positive result. Under a stationary Gaussian AR(1) alternative, 22 waits detect a population rank correlation of 0.288 in only 32 percent of trials. Thus this null result does not exclude moderate memory or confirm a physical stress law. Shared-date errors, missed glitches and cadence changes remain limits. No new event or planet is reported. Frozen rows, code, provenance, controls and offline steps are included. Job sci-1107-dell-astronomy-4ed7e950b9c7; machine dell; model gpt-6.1-sol.
