# Snapshot Merge Preview with K4 Lattice Visualization and Determinism Verification
|
|
|
|
## Module
|
|
Web
|
|
|
|
## Status
|
|
IMPLEMENTED
|
|
|
|
## Description
|
|
Snapshot management UI with merge preview showing per-CVE source contributions with trust scores, K4 lattice visualization, merge traces, missing evidence indicators, REPLAY.yaml format for deterministic replay, and verify-determinism component. (Merged with Snapshot Merge Preview from Phase 2 AirGap section.)
|
|
|
|
## Implementation Details
|
|
- **Feature directory**: `src/Web/StellaOps.Web/src/app/shared/components/lattice-diagram/`
|
|
- **Components**:
|
|
- `lattice-diagram` (`src/Web/StellaOps.Web/src/app/shared/components/lattice-diagram/lattice-diagram.component.ts`)
|
|
- **Source**: Feature matrix scan
|
|
|
|
## 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 visualization renders correctly with sample data
|
|
- [ ] Verify interactive elements (hover tooltips, click-to-drill-down) work
|
|
- [ ] Verify the visualization handles empty/minimal data gracefully
|
|
- **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)
