At 2025-04-30 the naive squared errors are 10.89 (h=1) and 21.16 (h=2), against 1.89 and 4.07 for the AR(1); the 2025-12-31 origin adds more. At h=1 the AR(1) is worse at 3 of 8 origins, including 2025-01-31 (8.03 vs 6.76). The report gives the 5/8 count but never says that one or two origins drive most of the 26%/38% gain.",9 "suggested_fix": "State that the improvement is driven mostly by the 2025Q1 swing (origins 2025-04-30 and 2025-12-31).

All required keys are present, and forecasts.csv has the expected 32 rows. The information rules are respected: each origin uses only its own vintage file, current_vintage.csv is used only for the revision statistic, and actuals come from first_release.csv with a check that each was published after its origin. The naive forecast follows the specification. Counts, exclusions, the revision statistic (0.5625, checked by hand) and the DM summaries are consistent. The claims are hedged appropriately: the gain is described as not significant at 5%, with n=8. The remaining issues are minor wording and robustness points."27}28
