The data hash matches data/README.md. Independent checks confirm the counts: 5217 rows, 215 empty, 5001 changes split 2500/2501, and the -51 bp extreme on 2009-03-18. The code follows the TASK rules. Empty rows are dropped before differencing, and each change is dated to the weekday of t. Weekday forecast means come from changes dated on or before 2009-12-31 only. The joint test is the classical equal-variance f_oneway on all changes, and the Monday interval is a Welch interval, as the report states. All required keys are present. The conclusion code follows the prescribed rule (ANOVA p=0.90). The out-of-sample comparison against the zero-change baseline is reported, including the slight deterioration and a DM-type test (p=0.058). The table, figure and report sections meet the spec. The claims match the numbers and carry fitting caveats. The limitations are honest: Levene rejects equal variances, the mandated test is kept anyway, and the report notes multi-day post-holiday changes, the single split, and limited power below about 0.4 bp. Only minor wording issues remain."27}28
