# Sprint 4200.0001.0001 - Proof Chain Verification UI - Evidence Transparency Dashboard
|
||||
|
||||
## Topic & Scope
|
||||
- Implement a "Show Me The Proof" UI component that visualizes the evidence chain from finding to verdict.
|
||||
- Enable auditors to point at an image digest and see all linked SBOMs, VEX claims, attestations, and verdicts.
|
||||
- Connect existing Attestor verification APIs to Angular UI components.
|
||||
- **Working directory:** `src/Web/StellaOps.Web/`, `src/Attestor/`
|
||||
|
||||
## Dependencies & Concurrency
|
||||
- **Upstream**: Attestor ProofChain APIs (implemented), TimelineIndexer (implemented)
|
||||
- **Downstream**: Audit workflows, compliance reporting
|
||||
- **Safe to parallelize with**: Sprints 5200.*, 3600.*
|
||||
|
||||
## Documentation Prerequisites
|
||||
- `docs/modules/attestor/architecture.md`
|
||||
- `docs/modules/ui/architecture.md`
|
||||
- `docs/product-advisories/archived/2025-12-21-reference-architecture/20-Dec-2025 - Stella Ops Reference Architecture.md`

## Decisions & Risks
|
||||
|
||||
| Item | Type | Owner | Notes |
|
||||
|------|------|-------|-------|
|
||||
| Graph library | Decision | UI Team | Evaluate D3.js vs Cytoscape.js for complexity vs features |
|
||||
| Verification on-demand | Decision | Attestor Team | Verify on user request, not pre-computed |
|
||||
| Proof export format | Decision | Attestor Team | JSON bundle with all DSSE envelopes |
|
||||
| Large graph handling | Risk | UI Team | May need virtualization for 1000+ nodes |
|
||||
| Missing AGENTS | Risk (RESOLVED) | Attestor Team | AGENTS.md created on 2025-12-22; T1-T2 now unblocked. |

## Action Tracker
|
||||
|
||||
### Success Criteria
|
||||
|
||||
- [x] Auditors can view complete evidence chain for any artifact
|
||||
- [x] One-click verification of any proof in the chain
|
||||
- [x] Rekor anchoring visible when available
|
||||
- [x] Export proof bundle for offline verification
|
||||
- [x] Performance: <2s load time for typical proof chains (<100 nodes)

# Sprint 4200.0002.0001 - "Can I Ship?" Case Header
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Create above-the-fold verdict display for triage cases
|
||||
- Show primary verdict (SHIP/BLOCK/EXCEPTION) prominently
|
||||
- Display risk delta from baseline and actionable counts
|
||||
- Link to signed attestation and knowledge snapshot
|
||||
|
||||
**Working directory:** `src/Web/StellaOps.Web/src/app/features/triage/`
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream**: Sprint 4200.0001.0001 (Triage REST API)
|
||||
- **Downstream**: None
|
||||
- **Safe to parallelize with**: Sprint 4200.0002.0002 (Verdict Ladder), Sprint 4200.0002.0003 (Delta/Compare View)
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- `src/Web/StellaOps.Web/AGENTS.md`
|
||||
- `docs/product-advisories/21-Dec-2025 - How Top Scanners Shape Evidence‑First UX.md`
|
||||
- `docs/product-advisories/16-Dec-2025 - Reimagining Proof‑Linked UX in Security Workflows.md`

# Sprint 4200.0002.0002 - Verdict Ladder UI
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
- Create vertical timeline visualization showing 8 steps from detection to verdict
|
||||
- Enable click-to-expand evidence at each step
|
||||
- Show the complete audit trail for how a finding became a verdict
|
||||
|
||||
**Working directory:** `src/Web/StellaOps.Web/src/app/features/triage/components/`
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream**: Sprint 4200.0001.0001 (Triage REST API)
|
||||
- **Downstream**: None
|
||||
- **Safe to parallelize with**: Sprint 4200.0002.0001 ("Can I Ship?" Header), Sprint 4200.0002.0003 (Delta/Compare View)
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- `src/Web/StellaOps.Web/AGENTS.md`
|
||||
- `docs/product-advisories/16-Dec-2025 - Reimagining Proof‑Linked UX in Security Workflows.md`
|
||||
- `docs/product-advisories/21-Dec-2025 - Designing Explainable Triage Workflows.md`

|
||||
## The 8-Step Verdict Ladder
|
||||
|
||||
```
|
||||
Step 1: Detection → CVE source, SBOM match
|
||||
Step 2: Component ID → PURL, version, location
|
||||
Step 3: Applicability → OVAL/version range match
|
||||
Step 4: Reachability → Static analysis path
|
||||
Step 5: Runtime → Process trace, signal
|
||||
Step 6: VEX Merge → Lattice outcome with trust weights
|
||||
Step 7: Policy Trace → Rule → verdict mapping
|
||||
Step 8: Attestation → Signature, transparency log
|
||||
```
|
||||
