The user fills it in at their own pace, then re-invokes you. ### Phases (used to structure questions) **Phase 1: Feature Understanding** — What is the feature? What triggers it? Inputs/outputs? Entities? **Phase 2: Entity Relationships & Aggregate Boundaries** — Which entity is the aggregate root? What invariants does it enforce? Which entities are independent? The aggregate root determines: 1. Which validation methods live on the domain model (e.g., `project.CanReceiveNotification()`) 2. Which app service methods must load the parent before operating on children 3. Which contract tests must cover "parent in invalid state → child operation rejected" If the user says "it's just a simple CRUD entity with no parent constraints", that entity is its own aggregate root — document it as such and move on.
