What common mistake do developers make with Idempotent seed strategies, why does the mistake cause problems, and what is the safer approach? One recurring problem with idempotent seed strategies is applying it without understanding the boundary it protects. Putting environment-specific secrets or irreversible production cleanup logic into a seeder that developers may run accidentally. In addition, Seeders that can safely be re-run are easier to use in deployment and local setup workflows. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
