# VEX Trust Column in Findings and Triage Lists

## Module
Web

## Status
VERIFIED

## Description
New sortable Trust column added to findings-list and triage-list grids. Shows a VexTrustChipComponent with color-coded confidence level (high/medium/low/unknown) and a VexTrustPopoverComponent on hover with detailed breakdown of issuer trust, statement quality, and coverage scores. Includes Storybook stories for design documentation.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/shared/components/vex-trust-chip/`
- **Components**:
  - `vex-trust-chip` (`src/Web/StellaOps.Web/src/app/shared/components/vex-trust-chip/vex-trust-chip.component.ts`)
  - `vex-trust-popover` (`src/Web/StellaOps.Web/src/app/shared/components/vex-trust-popover/vex-trust-popover.component.ts`)
- **Integration surfaces**:
  - Findings list: `src/Web/StellaOps.Web/src/app/features/findings/findings-list.component.ts`
  - Findings template: `src/Web/StellaOps.Web/src/app/features/findings/findings-list.component.html`
  - Triage list: `src/Web/StellaOps.Web/src/app/features/triage/components/triage-list/triage-list.component.ts`
  - Triage model contract: `src/Web/StellaOps.Web/src/app/features/triage/services/vulnerability-list.service.ts`
- **Behavior coverage**:
  - `src/Web/StellaOps.Web/src/tests/triage/vex-trust-column-in-findings-and-triage-lists.behavior.spec.ts`
- **Source**: SPRINT_1227_0004_0002_FE_trust_column.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 triage list loads with findings/items to review
  - [ ] Verify triaging actions (accept, dismiss, override) update item status
  - [ ] Verify keyboard shortcuts work for rapid triage navigation
- **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/vex-trust-column-in-findings-and-triage-lists/run-001/`
- Date (UTC): 2026-02-11
- Tier 0: PASS (path map corrected to include findings-list and triage-list trust integrations; symbols verified).
- Tier 1: PASS (`npm run test` focused + regression include suite: 39 files / 179 tests; `npm run build` passed with baseline warnings only).
- Tier 2: PASS (findings/triage trust rendering, trust sort semantics with deterministic tie-breaks, and hover/click trust popover interactions verified via Angular behavior harness).
