Todo app domain rules should enforce that each Task belongs to exactly one User, restrict Users from accessing others' tasks, define valid status transitions, and require explicit deletion to ensure consistent lifecycle management across CLI, web, and mobile interfaces.

Define core Todo entities as Task and User, with attributes including id, title, description, status, created_at, and updated_at. This establishes a consistent data model capturing essential task properties and relationships for reliable implementation.

Model valid status transitions by codifying explicit lifecycle constraints within the Todo domain rules, ensuring tasks move only through permitted statuses to prevent ambiguous state changes and maintain consistent implementation across interfaces.

Yes, the Todo domain model is designed for software engineers, product teams, and AI agents building apps across CLI, web, and mobile interfaces, providing UX guidance for clear confirmations and helpful error messages in each environment.

Explicit deletion rules prevent accidental data loss by requiring deliberate confirmation before removing Todo tasks. This domain constraint ensures lifecycle integrity and supports clear UX confirmations across CLI, web, and AI agent interfaces.

Implement access control domain rules specifying that each Task belongs to exactly one User and Users cannot access others' tasks. This constraint ensures secure task isolation and consistent authorization across CLI, web, and mobile platforms.
