+# A/B Deploy Diff Panel
+
+## Module
+Web
+
+## Status
+VERIFIED
+
+## Description
+Deploy diff UI provides deterministic A/B SBOM comparison with policy-hit context, loading/error states, and inline release action controls.
+
+## Implementation Details
+- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/deploy-diff/`
+- **Route module**: `src/Web/StellaOps.Web/src/app/features/deploy-diff/deploy-diff.routes.ts`
+- **Core files**:
+  - `src/Web/StellaOps.Web/src/app/features/deploy-diff/pages/deploy-diff.page.ts`
+  - `src/Web/StellaOps.Web/src/app/features/deploy-diff/components/deploy-diff-panel/deploy-diff-panel.component.ts`
+  - `src/Web/StellaOps.Web/src/app/features/deploy-diff/services/deploy-diff.service.ts`
+- **Focused tests**:
+  - `src/Web/StellaOps.Web/src/tests/deploy_diff/deploy-diff-panel.component.spec.ts`
+
+## Follow-up Notes
+- Tier 2 verification is integration-harness based because deploy-diff route wiring exists in feature module but is not mounted in the primary shell route map.
+
+## Verification
+- Date: 2026-02-10
+- Run artifacts: `docs/qa/feature-checks/runs/web/a-b-deploy-diff-panel/run-001/`
