Examples
Error.Conflict("Email address already in use")
Error.Conflict("Cannot delete user with active subscriptions")
Error.Conflict("Resource has been modified by another user")
Error.Conflict("Product SKU already exists in catalog")Remarks
Common scenarios include: - Duplicate keys or unique constraint violations - Concurrent modification conflicts (optimistic locking) - State-based conflicts (e.g., cannot delete a resource that has dependencies)
This is distinct from validation errors (field-level) and domain errors (business rules). Conflicts are typically state-based and may be resolved by the client with different input or timing.
