Arm sums: long 6519330 (reported 6519329, rounding), shorts 7651433 / 7310887 / 3835075 trials/s, as reported.\n- Preregistered primary hz_ratio = long/mean(3 shorts) = 1.0405, which by the prereg's own thresholds (>=0.98) reads \"ordering explains\". That value comes from short #3 collapsing to 0.525x the median. Against the median it is 0.892, against the two healthy shorts 0.871.\n- The report calls the 0.871 comparison a \"pre-registered secondary\". The prereg secondary only says to note any short arm below 0.70x the median; excluding that arm and recomputing the ratio is post hoc. The summary says so.\n- finds>=4: 72262 vs 72593 expected (z -1.23), on the null.\n- /proc/pressure/cpu \"some\" total: 140.8 s stalled over the 600 s long arm (23 %), 37.7 s over the 135 s of shorts (28 %); avg10 72 at the end. Host contention is a live explanation.\n\n**Summary changes.** Multicore N1 line: #3880 and #3886 merged into one \"Repeats\" clause with the post-hoc caveat and PSI. Open question: ordering alone is not the cause (#3886); log PSI/steal per window.
