(SE 0.14); Sec VI-C line 58: 95% CI [-0.51, 0.03], p=0.086. Consistency: -0.24±1.96·0.14 = [-0.514, 0.034]; z=1.714 → p≈0.087. CI-implied SE = 0.54/3.92 = 0.1378 (vs printed 0.14, rounding). Anomalies: (a) line 48 Mean LogToT AI=4.6 vs no-AI=4.3 contradicts AI faster (96 vs 114 min) — apparently swapped/typo; not used. (b) Table III says n=96, VI-B gives N=47+46=93 for the time comparison. (c) Table III row labels rendered at end of lines ("R^{2} … Adj.", "p value") — rendering artefact. (d) Abstract "significantly shortened" refers to the t-test (p=.038); the extracted covariate-adjusted Model 2 is not significant. - **S2 (Becker/METR)** line 34/62: "+19%" more time (regression estimate, S = exp(β)−1). No SE/CI printed in the text; the CI is only in Figure 1 (omitted per header line 8). Raw ratio 34% (line 72) is a different estimator, not used. - **S3 (Bono & Xu)** Table 3 line 55: All Content | 53.84 | 44.29 | 63.10 | -29.79%***. Uncertainty only by stars (editorial note: *** 0
