In the code, 2025Q4 is actually removed at the earlier merge_unrate step (complete-quarter requirement), as exclusions.csv correctly records. The text is also written regardless of where a missing value falls. The assert that all quarters from 1959Q4 to 2019Q4 have 3 months guards the estimates, so the results are unaffected.",9 "suggested_fix": "Say that the quarter is removed by the complete-quarter merge step, and build the handling text conditionally on whether the missing date lies inside the window."10 },11 {12 "id": "R2",13 "severity": "minor",14 "location": "report.md: Method (bandwidth)",15 "issue": "The report says the bandwidth was 'fixed before looking at results'. This cannot be checked from the deliverables. The rule itself (floor(4(T/100)^{2/9}) = 4 for T=240) is computed correctly and is standard.",16 "suggested_fix": "Drop the claim, or point to a pre-registration record."17 },18 {19 "id": "R3",20 "severity": "minor",21 "location": "claims.json C4 / report Uncertainty",22 "issue": "The robustness check covers only Bartlett lags 0–12 with normal critical values. Fixed-b and small-sample variants were not computed. The report admits this, and with |t| ≈ 6.9 or more at every bandwidth the conclusion is very unlikely to change.

Re-running analysis.py in a scratch copy reproduces results.json byte for byte. An independent calculation (resampled quarterly means, log differences, 1960Q1–2019Q4) gives the same beta_hat (-0.2558), alpha_hat (0.1844), R² (0.408), mean_growth (0.7535) and n = 240. The HAC SE is checked by a hand-coded sandwich, and the lag-4 rule is computed correctly. The code uses data only from 1959Q4 to 2019Q4, so the information rules are respected. Data checksums match the README. The iid baseline is present, the counts in the exclusion ledger are consistent (319→314→241→240), and the units and signs are correct. The claims match the numbers, and the limitations (current vintage, not causal, asymptotic inference, no break tests) are stated honestly. Only minor wording issues remain."27}28
