# Verdict "Why" Summary Bullets Component

## Module
Web

## Status
VERIFIED

## Description
Component displaying 3-5 bullet-point explanations of verdict drivers for a given delta verdict, enabling quick PM understanding of why a release was marked Routine/Review/Block.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/verdicts/`
- **Components**:
  - `policy-breadcrumb` (`src/Web/StellaOps.Web/src/app/features/verdicts/components/policy-breadcrumb/policy-breadcrumb.component.ts`)
    - deterministic `summaryBullets` derivation with fallback semantics and max-5 cap
    - `trackBySummaryBullet(...)` for stable bullet rendering
- **Behavior coverage**:
  - `src/Web/StellaOps.Web/src/tests/verdicts/verdict-why-summary-bullets-component.behavior.spec.ts`
- **Source**: SPRINT_20251226_004_FE_risk_dashboard.md and QA summary-bullets implementation hardening in Sprint `SPRINT_20260211_029_FE_web_feature_verification_batch40`.

## E2E Test Plan
- **Setup**:
  - [ ] Log in with a user that has appropriate permissions
  - [ ] Navigate to `/triage/artifacts/:artifactId`
  - [ ] 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/verdict-why-summary-bullets-component/run-001/`
- Date (UTC): 2026-02-11
- Tier 0: PASS (source/symbol verification; implemented missing why-summary bullet rendering, deterministic ordering/track keys, and supported behavior harness).
- Tier 1: PASS (`npm run test` focused + regression include suite: 33 files / 152 tests; `npm run build` passed with baseline warnings).
- Tier 2: PASS (deterministic summary ordering, fallback behavior, and 5-bullet cap validated via Angular behavior harness).
