# Unified Triage Canvas with Rich Evidence

## Module
Web

## Status
VERIFIED

## Description
A full triage workspace combining reachability evidence graphs, witness call paths, and proof tree visualizations in a single canvas for evidence-rich triage decisions.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/triage/components/triage-canvas/`
- **Components**:
  - `triage-canvas` (`src/Web/StellaOps.Web/src/app/features/triage/components/triage-canvas/triage-canvas.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 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/unified-triage-canvas-with-rich-evidence/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).
