# 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
- Primary shell route map now mounts `/deploy/diff` via `src/Web/StellaOps.Web/src/app/app.routes.ts`, enabling strict end-user Tier 2 replay.
