The counts reconcile: 2140 rows read, minus 40 exact duplicates gives 2100, minus 300 origin-2022 rows with no outcome gives 1800 firm-years from 300 firms. The ledger arithmetic is consistent on every row. rating_2025, which leaks future information, is correctly excluded from the model and from analytic.csv. The predictors match the estimand, standard errors are clustered by firm, and the baseline default rate is reported. The claims match the numbers and are suitably hedged (association, not causation; synthetic data). The two issues found are minor and concern documentation only."20}21
