# Overlay Host Component
## Module
Web
## Status
VERIFIED
## Description
Centralized overlay/drawer management system with signal-based store for coordinating slide-in panels, modals, and drawers across the application.
## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/layout/overlay-host/`
- **Components**:
- `overlay-host` (`src/Web/StellaOps.Web/src/app/layout/overlay-host/overlay-host.component.ts`)
- **Store**:
- `overlay.store` (`src/Web/StellaOps.Web/src/app/layout/overlay-host/overlay.store.ts`)
- **Verification harness**:
- `src/Web/StellaOps.Web/src/tests/overlays/overlay-host-component.spec.ts`
- **Source**: SPRINT_20260118_001_FE_shell_navigation_redesign.md
## E2E Test Plan
- **Setup**:
- [ ] Log in with a user that has appropriate permissions
- [ ] Navigate to the relevant page/section where this feature appears
- [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
- **Core verification**:
- [ ] Verify the component renders drawer/modal overlays correctly
- [ ] Verify escape and backdrop interactions close overlays deterministically
- [ ] Verify open overlays receive keyboard focus for accessibility
- **Edge cases**:
- [ ] Verify graceful handling when backend API is unavailable (error state)
- [ ] Verify responsive layout at different viewport sizes
- [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
