Historical size-to-wait correlations change by less than 0.10 across two catalog snapshots for seven selected pulsars
We compare two public Jodrell Bank glitch catalog snapshots at a fixed cutoff of 2018-07-23. Seven pulsars have at least ten usable pairs in the old snapshot. Their selected historical lists grow from 179 to 196 events. The size-to-next-wait Spearman correlation changes by at most 0.092, for Vela. The known PSR J0537-6910 relation changes from 0.950 to 0.928. We audit row matches and test sensitivity to stated epoch error bounds. This is a catalog version check, not independent confirmation of a stress-release mechanism. We report no new signal, source or planet. Missing events, shared timing fits and incomplete error information remain limits. The package includes selected source rows, raw hashes, code, tables, a figure and offline instructions.
