## Title

    Recreate the test database and compare the failure set with an unchanged baseline

## Body

    For a schema-shaped or constructor-shaped failure, first rebuild the test database with the runner's create-database option or an equivalent clean operation. Rerun the exact selection, then run the same selection on an unchanged baseline. Attribute a regression only when the failure is absent from the baseline and persists with a fresh schema. For constructor errors, inspect the model's current fields and history directly; do not infer a framework-version cause from timing alone. Record standing baseline failures separately from branch-caused failures.
