  "deviation_evidence": "Recorded before this track's software-reference run and before any dry run, from the paper and the research probe: Table I does not state how its standard errors were computed, and the research note (research-papers.md section 3.13, 2026-10-14) already reported the cluster-by-id (here equal to HC1) error of this regression on this extract as 1.9512, which rounds to 2.0 against the printed 1.9. The printed cell is recorded and non-required on T1; the reference keeps HC1. Found in a dry run (20261015T073042Z-suite-paper_repro-scripted-7a58d8, T1): the coefficient on this extract is 21.2839 (tool and reference agree), which misses the printed 21.2 by more than half a unit of its last decimal; the Mixtape prints 21.28 from the same extract, so the causaldata extract is not the authors' exact file (a data_version difference on top of the SE convention). Tolerance and reference call unchanged. At the B-join review the kind was relabelled data_version (it was se_convention, which did not describe the value miss); the printed value stays non-required on T1 because of this post-run finding, which the page shows as found in a run.",

Table notes: 'Standard errors are in parentheses'; the sample keeps elections with the Democrat vote share at time t strictly between 48 and 52 percent; sample size 915. Data check made before any estimate: in the causaldata extract, rows with 0.48 < lagdemvoteshare < 0.52 number 915, as printed, with no missing outcome or treatment, no share exactly at 0.48, 0.50 or 0.52, lagdemocrat equal to (lagdemvoteshare > 0.5) on every row of the window, and id unique within the window."
