# Unknowns Tracking UI

## Module
Web

## Status
VERIFIED

## Description
Unknowns tracking UI with component list showing confidence scores, identification candidates, manual resolution workflow, fingerprint matching, and SBOM completeness impact analysis.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/unknowns-tracking/`
- **Routes**: `unknowns.routes.ts`
- **Components**:
  - `determinization-review` (`src/Web/StellaOps.Web/src/app/features/unknowns-tracking/determinization-review.component.ts`)
  - `grey-queue-dashboard` (`src/Web/StellaOps.Web/src/app/features/unknowns-tracking/grey-queue-dashboard.component.ts`)
  - `unknown-detail` (`src/Web/StellaOps.Web/src/app/features/unknowns-tracking/unknown-detail.component.ts`)
  - `unknowns-dashboard` (`src/Web/StellaOps.Web/src/app/features/unknowns-tracking/unknowns-dashboard.component.ts`)
- **Source**: SPRINT_20251229_033_FE_unknowns_tracking_ui

## E2E Test Plan
- **Setup**:
  - [ ] Log in with a user that has appropriate permissions
  - [ ] Navigate to `/analyze/unknowns`
  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
- **Core verification**:
  - [ ] Verify the component renders correctly with sample data
  - [ ] Verify interactive elements respond to user input
  - [ ] Verify data is fetched and displayed from the correct API endpoints
- **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)
## Verification
- Run ID: docs/qa/feature-checks/runs/web/unknowns-tracking-ui/run-001/
- Date (UTC): 2026-02-11
- Tier 0: PASS (source/symbol verification for feature contracts and behavior harness references).
- Tier 1: PASS (focused behavior suite: 4 files / 16 tests; npm run build passed with known baseline warnings).
- Tier 2: PASS (feature-specific behavioral validation via Angular test harness interactions and deterministic assertions).
