AA98-F03 Workbench Startup and Composition

Parent

• Epic: DevOps/Epics/AA98-E01-Workbench-and-Shell.md
• Vision: DevOps/Vision.md

Goal

Establish the startup composition path for the shell so the application opens reliably, wires the first services through dependency injection, and can evolve toward a component-based workbench.

Scope

• Define shell startup responsibilities.
• Wire the first shell-related services into dependency injection.
• Define how the main window and workbench parts are composed.
• Prepare a clean path for later component registration.

Included

• Application startup flow
• Shell service registration
• Main window creation and initialization
• Composition boundaries between shell, editor, and future components

Excluded for Now

• Dynamic plugin discovery
• Advanced module lifecycle management
• External provider loading
• Full component marketplace or package scenarios

Success Indicators

• The application starts consistently into the intended workbench.
• Shell composition remains understandable and testable.
• Later components can be integrated through defined composition seams.

Candidate Backlog Items

• Define startup sequence for shell initialization
• Register shell services and view models with dependency injection
• Separate shell composition from editor-specific composition
• Prepare extension points for future component registration

Assumptions

• Early composition should remain explicit and local to the application startup path.
• Component extensibility should begin with internal extension points before external plugins are considered.

Open Questions

• Which shell services belong in the application layer versus the UI layer?
• When should component discovery move from explicit registration to a more flexible model?

Status

• Proposed
