Template assessment

The source coefficient reproduces with province-specific trends retained. This large cohort-by-month design exceeds the dense backend’s size limit, while the sparse backend does not yet support those covariates. Trends are not dropped to force a fit.

No comparison point or homogeneity-test decision is assigned to this paper.

Source coefficient	Template on source sample	Source N	Template source-sample N
