Common problems and fixes
Generated emails collide with a unique constraint.
Enable “Guarantee unique” on the email field, which appends a counter rather than relying on chance.
Dates fall outside my test range.
Each date field has explicit start and end bounds — set them rather than using the default ten-year window.
