That bound comes from an i.i.d. Welch/HC1 standard error. The report itself says volatility clustering and serial dependence were not addressed, so the bound is conditional on independence and should not be stated as a firm exclusion.",9 "suggested_fix": "Qualify the bound as holding under independence, or add a HAC (Newey-West) standard error for the Monday-dummy regression."10 },11 {12 "id": "R2",13 "severity": "minor",14 "location": "out/report.md (Limitations, holiday-spanning bullet)",15 "issue": "The report says the 214 holiday-spanning changes 'cover more than one trading day'.

Counts are consistent: 5217 rows minus 215 missing minus 1 first observation gives 5001 changes, split 2500 + 2501, and table1 n sums to 5001. The ANOVA is the required classical F-test over all changes. The Monday contrast uses a Welch interval, the choice is stated, and an independent HC1 regression agrees. The weekday-mean forecasts use estimation-period data only. The conclusion code follows the stated rule. The report has the six required sections in order. Its claims match the numbers and are suitably hedged. Limitations are discussed honestly: the Levene rejection, serial dependence, holiday-spanning changes, regimes and power. Only minor wording and precision points remain."27}28
