What is Idempotent seed strategies in Laravel, and what role does it play in a real application? In Laravel, idempotent seed strategies should be understood as part of a larger application architecture rather than as an isolated API call. Seeders that can safely be re-run are easier to use in deployment and local setup workflows. A strong understanding includes its purpose, the layer where it belongs, the data or request flow it affects, and the situations where another mechanism may be more appropriate. Practical context: Seeders provide intentional data-loading workflows while model factories generate realistic model records for development and testing. The specific focus here is idempotent seed strategies: Seeders that can safely be re-run are easier to use in deployment and local setup workflows. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
