+# Evidence Presentation UX (Panels, Drawers, Rail, Export Center)
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Comprehensive evidence presentation: tabbed panels across triage/findings/SBOM/policy views with reachability, binary diff, provenance, policy, and attestation chain tabs. Per-finding evidence drawer, right-rail proof pane with witness path call traces, DSSE badges, confidence meters. Evidence export center with audit bundle creation. TTE metrics tracking.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/shared/components/evidence-drawer/`
+- **Components**:
+  - `evidence-drawer` (`src/Web/StellaOps.Web/src/app/shared/components/evidence-drawer/evidence-drawer.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 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: docs/qa/feature-checks/runs/web/evidence-presentation-ux/run-001/
+- Tier 0 (source): pass (	ier0-source-check.json)
+- Tier 1 (build/tests): pass (	ier1-build-check.json)
+- Tier 2 (behavior): pass (	ier2-e2e-check.json)
+- Verified on (UTC): 2026-02-10
+
+## Recheck (run-003)
+- Date (UTC): 2026-02-11T06:44:05Z
+- Status: VERIFIED (strict Tier 2 UI replay)
+- Tier 2 evidence: `docs/qa/feature-checks/runs/web/evidence-presentation-ux/run-003/tier2-ui-check.json`
+- Notes: Strict evidence-center drawer flow now verifies signed/verified presentation states and contents-section interaction from an end-user route.
