# Proof Ledger View (Merkle Tree Scan History)
## Module
Web
## Status
VERIFIED
## Description
Interactive proof ledger displaying scan proof history with Merkle tree visualization, proof bundle download, and a Score Replay Dashboard for triggering and monitoring deterministic score replay operations with before/after comparison.
## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/features/proofs/`
- **Components**:
- `proof-ledger-view` (`src/Web/StellaOps.Web/src/app/features/proofs/proof-ledger-view.component.ts`)
- **Services**:
- `manifest-api` (`src/Web/StellaOps.Web/src/app/core/api/proof.client.ts`)
- `proof-bundle-api` (`src/Web/StellaOps.Web/src/app/core/api/proof.client.ts`)
- **Models**:
- `src/Web/StellaOps.Web/src/app/core/api/proof.models.ts`
- **Source**: Feature matrix scan
## E2E Test Plan
- **Setup**:
- [ ] Log in with a user that has appropriate permissions
- [ ] Navigate to `/proofs/:subjectDigest`
- [ ] 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/proof-ledger-view/run-001/`
