Feature Specification: Service Launchpad

1. Overview & Vision

The Launchpad is the "Desktop" of the Agentic Enterprise OS. It provides a centralized, personalized interface for discovering and launching all authorized applications within the VENI-AI ecosystem, ensuring seamless navigation between federated modules.

2. Personas & Stakeholders

Persona	Goal
End User	Quick access to work tools without re-authentication.
System Admin	Register and manage the availability of satellite modules.

3. User Stories

• As a user, I want to see only the apps I have permission to use so my workspace remains clean.
• As a developer, I want to register a new remote app so it appears instantly on the user's dashboard.

4. Functional Requirements (FR)

• REQ-LP-001: Dynamic discovery of registered satellite modules.
• REQ-LP-002: Permission-based app visibility (RBAC).
• REQ-LP-003: Micro-frontend lifecycle management (Mount/Unmount).
• REQ-LP-004: App categories and search/filter.

5. Non-Functional Requirements (NFR)

• Load Time: Launchpad metadata retrieval < 200ms.
• Resilience: Shell must stay functional even if one remote app is down.

6. Business Logic & Rules

• Discovery: Apps are loaded via a public registry endpoint.
• Isolation: Each app runs in a scoped container to prevent CSS/JS pollution.
• State Preservation: The Shell persists the "last used app" for the next session.

7. User Interface (UI/UX)

• Grid-based dashboard with rich app icons and metadata.
• Left-rail sidebar for global navigation.
• "App Loading" skeletons and error boundaries for remote failures.

8. Information Architecture

• Primary entry point after login.
• Hierarchical grouping: Core Apps (Drive, HRM) vs. Extended Apps (Auto Report).

9. Data Model & Persistence

• Table: apps (Registry).
• Table: user_app_preferences (Personalization).

10. API & Service Layer

• GET /api/config/apps
• POST /api/admin/apps

11. Integration Patterns

• Module Federation: Dynamic loading of remote entry files.
• Shared Dependencies: React and common UI kits shared between Host and Remote.

12. Security & Permissions

• Visibility: Controlled by apps:read scope.
• Integrity: Remote entry URLs must be served over HTTPS with valid certificates.

13. Error Handling & Resilience

• Error boundaries catch "Module Not Found" errors.
• Fallback UI when a remote application fails to mount.

14. Performance & Scalability

• Parallel loading of app metadata.
• Pre-fetching of the next app's assets (planned).

15. Globalization & i18n

• Support for localized App Display Names and Descriptions.

16. Accessibility (a11y)

• Keyboard navigation (Tab index) for app cards.
• Screen reader announcements for app status changes.

17. Observability & Analytics

• Tracking of "App Launch" events to measure module popularity.
• Monitoring of "App Failure" rates for DevOps alerts.

18. Testing & Quality

• Cypress tests for cross-module navigation.
• Visual regression testing for the dashboard layout.

19. Constraints & Assumptions

• Assumes remote apps follow the standard ShellEntry contract.

20. Future Enhancements

• User-defined app shortcuts and favorites.
• Widget system for the dashboard (e.g., "Recent Files" from Drive).
