db-only-slice

To add an EF Core column without application logic, use a database-only schema slice that updates domain entities, fluent configurations, and DbContext registration. This isolates persistence layer changes so no handlers or endpoints are generated.

A database-only schema slice in clean architecture is a feature slice that exclusively modifies EF Core domain entities, fluent configurations, DbContext registration, and migrations without adding application handlers, endpoints, or business logic.

To generate safe EF Core migrations for non-nullable columns, the database-only schema slice requires setting default values for non-nullable columns and validating indexes, foreign keys, and rollback behavior during migration generation.

Yes, you can use the database-only schema slice to update EF Core fluent configurations. It specifically supports defining table mapping, columns, relationships, indexes, and constraints within the infrastructure layer.

To validate EF Core migration rollback behavior, the database-only schema slice reviews generated migrations for destructive drops, missing defaults, and rollback coverage. This ensures safe migration generation and validates indexes and foreign keys.
