# Migration Contract Checks

Schema changes need tests at both the storage layer and any command that reports migration state.

## Steps

1. Add a migration test that checks the new table or column.
2. Add a repository test that proves the data survives reopening.
3. Update CLI or audit expectations that list migration versions.
