# Sprint: Diff-First Default View
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0005_0001 |
|
||||
| **Batch** | 001 - Quick Win |
|
||||
| **Module** | FE (Frontend) |
|
||||
| **Topic** | Diff-first default view toggle |
|
||||
| **Priority** | P0 - UX Improvement |
|
||||
| **Estimated Effort** | Very Low |
|
||||
| **Dependencies** | None (CompareView exists) |
|
||||
| **Working Directory** | `src/Web/StellaOps.Web/src/app/features/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Make the comparison (diff) view the default when navigating to findings, with easy toggle to detail view:
|
||||
1. Default to diff view showing changes between scans
|
||||
2. Remember user preference in local storage
|
||||
3. Highlight material changes using existing SmartDiff rules
|
||||
4. Preserve existing detail view as alternative
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `CompareViewComponent` fully implemented with 3-pane layout
|
||||
- `FindingsListComponent` is current default view
|
||||
- SmartDiff with R1-R4 detection rules operational
|
||||
- No user preference persistence for view mode
|
||||
|
||||
### Target State
|
||||
- Diff view as default on findings navigation
|
||||
- User toggle persisted in local storage
|
||||
- URL parameter override (`?view=detail` or `?view=diff`)
|
||||
- SmartDiff badges prominently displayed
|
||||
|
||||

|
||||
|
||||
## Deliverables
|
||||
|
||||
### D1: View Toggle Service
|
||||
**File:** `src/Web/StellaOps.Web/src/app/core/services/view-preference.service.ts`
|
||||
|
||||
```typescript
|
||||
@Injectable({ providedIn: 'root' })
|
||||
export class ViewPreferenceService {
|
||||
private readonly STORAGE_KEY = 'stellaops.findings.defaultView';
|
||||
private readonly DEFAULT_VIEW: ViewMode = 'diff';
|
||||
|
||||
private viewMode$ = new BehaviorSubject<ViewMode>(this.loadPreference());
|
||||
|
||||
getViewMode(): Observable<ViewMode> {
|
||||
return this.viewMode$.asObservable();
|
||||
}
|
||||
|
||||
setViewMode(mode: ViewMode): void {
|
||||
localStorage.setItem(this.STORAGE_KEY, mode);
|
||||
this.viewMode$.next(mode);
|
||||
}
|
||||
|
||||
private loadPreference(): ViewMode {
|
||||
const stored = localStorage.getItem(this.STORAGE_KEY);
|
||||
return (stored as ViewMode) || this.DEFAULT_VIEW;
|
||||
}
|
||||
}
|
||||
|
||||
export type ViewMode = 'diff' | 'detail';
|
||||
```
|
||||
|
||||
### D2: View Toggle Component
|
||||
**File:** `src/Web/StellaOps.Web/src/app/shared/components/view-toggle/view-toggle.component.ts`
|
||||
|
||||
```typescript
|
||||
@Component({
|
||||
selector: 'app-view-toggle',
|
||||
template: `
|
||||
<mat-button-toggle-group
|
||||
[value]="currentView()"
|
||||
(change)="onViewChange($event.value)"
|
||||
aria-label="View mode">
|
||||
<mat-button-toggle value="diff">
|
||||
<mat-icon>compare_arrows</mat-icon>
|
||||
Diff View
|
||||
</mat-button-toggle>
|
||||
<mat-button-toggle value="detail">
|
||||
<mat-icon>list</mat-icon>
|
||||
Detail View
|
||||
</mat-button-toggle>
|
||||
</mat-button-toggle-group>
|
||||
`
|
||||
})
|
||||
export class ViewToggleComponent {
|
||||
currentView = signal<ViewMode>('diff');
|
||||
|
||||
constructor(private viewPref: ViewPreferenceService) {
|
||||
this.viewPref.getViewMode().subscribe(mode => this.currentView.set(mode));
|
||||
}
|
||||
|
||||
onViewChange(mode: ViewMode): void {
|
||||
this.viewPref.setViewMode(mode);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### D3: Findings Container Update
|
||||
**File:** `src/Web/StellaOps.Web/src/app/features/findings/findings-container.component.ts`
|
||||

selector: 'app-findings-container',
|
||||
template: `
|
||||
<div class="findings-header">
|
||||
<h1>Findings</h1>
|
||||
<app-view-toggle />
|
||||
</div>
|
||||

`
|
||||
})
|
||||
export class FindingsContainerComponent {

viewMode = signal<ViewMode>('diff');
|
||||
|
||||
constructor(
|
||||
private viewPref: ViewPreferenceService,
|
||||
private route: ActivatedRoute
|
||||
) {
|

const urlView = this.route.snapshot.queryParamMap.get('view');
|
||||
if (urlView === 'diff' || urlView === 'detail') {
|
||||
this.viewMode.set(urlView);
|
||||
} else {
|
||||
// Fall back to user preference
|

this.viewPref.getViewMode().subscribe(mode => this.viewMode.set(mode));
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### D4: SmartDiff Badge Enhancement
|
||||
**File:** `src/Web/StellaOps.Web/src/app/shared/components/diff-badge/diff-badge.component.ts`
|
||||
|
||||
Enhance existing badge to show rule type:
|
||||
|
||||
```typescript
|
||||
@Component({
|
||||
selector: 'app-diff-badge',
|
||||
template: `
|
||||
<span class="diff-badge" [class]="badgeClass()">
|
||||
<mat-icon>{{ icon() }}</mat-icon>
|
||||
{{ label() }}
|
||||
@if (tooltip()) {
|
||||
<mat-tooltip [matTooltip]="tooltip()" />
|
||||
}
|
||||
</span>
|
||||
`
|
||||
})
|
||||
export class DiffBadgeComponent {
|
||||
@Input() rule!: SmartDiffRule;
|
||||
|
||||
icon = computed(() => {
|
||||
switch (this.rule) {
|
||||
case 'R1': return 'call_split'; // reachability_flip
|
||||
case 'R2': return 'swap_horiz'; // vex_flip
|
||||
case 'R3': return 'trending_up'; // range_boundary
|
||||
case 'R4': return 'warning'; // intelligence_flip
|
||||
}
|
||||
});
|
||||
|
||||
label = computed(() => {
|
||||
switch (this.rule) {
|
||||
case 'R1': return 'Reachability Changed';
|
||||
case 'R2': return 'VEX Status Changed';
|
||||
case 'R3': return 'Version Boundary';
|
||||
case 'R4': return 'Risk Intelligence';
|
||||
}
|
||||
});
|
||||
}
|
||||
```
|
||||
|
||||
### D5: Route Configuration Update

| **Sprint ID** | SPRINT_1227_0005_0002 |
|

| **Batch** | 002 - Core Value |
|
||||
| **Module** | FE (Frontend) |
|
||||
| **Topic** | Proof tree display in finding cards |
|
||||
| **Priority** | P0 - Core Differentiator |
|
||||
| **Estimated Effort** | Low |
|
||||
| **Dependencies** | ProofSpine API available |
|
||||
| **Working Directory** | `src/Web/StellaOps.Web/src/app/features/findings/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Integrate ProofSpine visualization into finding cards:
|
||||
1. Display collapsible proof tree showing evidence chain
|
||||
2. Show ProofBadges (4-axis) at a glance
|
||||
3. Link each segment to detailed evidence view
|
||||
4. Highlight cryptographic chain integrity
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `ProofSpine` with 6 segment types exists in backend
|
||||
- `ProofBadges` model with 4 dimensions available
|
||||
- Finding cards show basic metadata only
|
||||
- No visual representation of evidence chain
|
||||
|
||||
### Target State
|
||||
- Each finding card has expandable proof tree
|
||||
- ProofBadges visible without expansion
|
||||
- Segment drill-down to evidence details
|
||||
- Chain integrity indicator (all digests valid)
|
||||

# Sprint: Copy Attestation & Audit Pack Export
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0005_0003 |
|
||||
| **Batch** | 003 - Completeness |
|
||||
| **Module** | FE (Frontend) + BE (Backend) |
|
||||
| **Topic** | Copy attestation button & audit pack export |
|
||||
| **Priority** | P1 - Compliance Feature |
|
||||
| **Estimated Effort** | Low-Medium |
|
||||
| **Dependencies** | AuditPack infrastructure exists |
|
||||
| **Working Directory** | `src/Web/StellaOps.Web/src/app/features/` + `src/__Libraries/StellaOps.AuditPack/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Add one-click evidence export capabilities:
|
||||
1. "Copy Attestation" button for DSSE envelope clipboard copy
|
||||
2. "Export Audit Pack" for downloadable evidence bundle
|
||||
3. Selective export (choose segments/findings)
|
||||
4. Format options (JSON, DSSE, ZIP bundle)
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `AuditBundleManifest` model defined
|
||||
- `EvidenceSerializer` with canonical JSON
|
||||
- DSSE signing infrastructure complete
|
||||
- No UI buttons for copy/export
|
||||
|
||||
### Target State
|
||||
- Copy button on finding cards and detail views
|
||||
- Export button for bulk download
|
||||
- Format selector (JSON/DSSE/ZIP)
|
||||
- Progress indicator for large exports
|
||||

|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0005_0004 |
|
||||
| **Batch** | 004 - Audit |
|
||||
| **Module** | BE (Backend) + LB (Library) |
|
||||
| **Topic** | Complete verdict replay infrastructure |
|
||||
| **Priority** | P1 - Audit Requirement |
|
||||
| **Estimated Effort** | Medium |
|
||||
| **Dependencies** | ReplayExecutor scaffolded |
|
||||
| **Working Directory** | `src/__Libraries/StellaOps.AuditPack/` + `src/Replay/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Complete the verdict replay infrastructure for audit purposes:
|
||||
1. Deterministic re-execution of findings verdicts
|
||||
2. Isolated replay context (no network, deterministic time)
|
||||
3. Verification that replayed verdict matches original
|
||||
4. Audit trail with replay attestations
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `ReplayExecutor` scaffolded with basic structure
|
||||
- `IsolatedReplayContext` model exists
|
||||
- `AuditBundleManifest` captures inputs
|
||||
- DSSE signing infrastructure complete
|
||||
|
||||
### Target State
|
||||
- Full deterministic replay capability
|
||||
- Input snapshot capture at verdict time
|
||||
- Replay produces identical output
|
||||
- Attestation proves replay match
|
||||

# Advisory Analysis: Binary-Fingerprint Backport Database
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Advisory ID** | ADV-2025-1227-001 |
|
||||
| **Title** | Binary-Fingerprint Database for Distro Patch Backports |
|
||||
| **Status** | APPROVED - Ready for Implementation |
|
||||
| **Priority** | P0 - Strategic Differentiator |
|
||||
| **Overall Effort** | Medium-High (80% infrastructure exists) |
|
||||
| **ROI Assessment** | HIGH - False positive reduction + audit moat |
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This advisory proposes building a binary-fingerprint database that auto-recognizes "fixed but same version" cases from distro backport patches. **Analysis confirms StellaOps already has 80% of required infrastructure** in the BinaryIndex module.
|
||||
|
||||
### Verdict: **PROCEED**
|
||||
|
||||
The feature aligns with StellaOps' core mission (VEX-first, deterministic, audit-friendly) and provides a rare competitive advantage. Most scanners rely on version matching; few verify at the binary level with attestable proofs.
|
||||

## Timeline (No Estimates)
|
||||
|
||||
**Recommended Sequence:**
|
||||
1. Batch 001 → Enables core functionality
|
||||
2. Batch 002 → Adds function-level attribution (can parallelize with 003)
|
||||
3. Batch 003 → User-facing polish
|
||||
|
||||
**Dependencies:**
|
||||
- 0002 depends on 0001 (uses VexBridge)
|
||||
- 0003 depends on 0002 (uses Resolution API)
|
||||
- 0002_0001 (builders) can start after 0001_0001 merge

|

|
||||
## Objective
|
||||
|
||||
Wire `BinaryVulnMatch` results from `IBinaryVulnerabilityService` to auto-generate `VexObservation` records with evidence payloads. This bridges the gap between binary fingerprint matching and the VEX decision flow.
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `IBinaryVulnerabilityService.LookupByIdentityAsync()` returns `BinaryVulnMatch[]` with CVE, confidence, and method
|
||||
- `GetFixStatusAsync()` returns `FixStatusResult` with state (fixed/vulnerable/not_affected)
|
||||
- VEX infrastructure (`VexObservation`, `VexLinkset`) is mature and append-only
|
||||
- No automatic VEX generation from binary matches exists
|
||||
|
||||
### Target State
|
||||
- Binary matches automatically produce VEX observations
|
||||
- Evidence payloads contain fingerprint metadata (build-id, hashes, confidence)
|
||||
- DSSE-signed attestations for audit trail
|
||||
- Integration with VexLens consensus flow
|
||||
|
||||

|
||||
|
||||
## Deliverables
|
||||
|
||||
### D1: IVexEvidenceGenerator Interface
|
||||
**File:** `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.VexBridge/IVexEvidenceGenerator.cs`
|
||||
|
||||
```csharp
|
||||
public interface IVexEvidenceGenerator
|
||||
{
|
||||
/// <summary>
|
||||
/// Generate VEX observation from binary vulnerability match.
|
||||
/// </summary>
|
||||
Task<VexObservation> GenerateFromBinaryMatchAsync(
|
||||
BinaryVulnMatch match,
|
||||
BinaryIdentity identity,
|
||||
FixStatusResult? fixStatus,
|
||||
VexGenerationContext context,
|
||||
CancellationToken ct = default);
|
||||
|
||||
/// <summary>
|
||||
/// Batch generation for scan performance.
|
||||
/// </summary>
|
||||
Task<IReadOnlyList<VexObservation>> GenerateBatchAsync(
|
||||
IEnumerable<BinaryMatchWithContext> matches,
|
||||
CancellationToken ct = default);
|
||||
}
|
||||
|
||||
public sealed record VexGenerationContext
|
||||
{
|
||||
public required string TenantId { get; init; }
|
||||
public required string ScanId { get; init; }
|
||||
public required string ProductKey { get; init; } // PURL
|
||||
public string? DistroRelease { get; init; } // e.g., "debian:bookworm"
|
||||
public bool SignWithDsse { get; init; } = true;
|
||||
}
|
||||
|
||||
public sealed record BinaryMatchWithContext
|
||||
{
|
||||
public required BinaryVulnMatch Match { get; init; }
|
||||
public required BinaryIdentity Identity { get; init; }
|
||||
public FixStatusResult? FixStatus { get; init; }
|
||||
public required VexGenerationContext Context { get; init; }
|
||||
}
|
||||
```
|
||||
|
||||
### D2: VexEvidenceGenerator Implementation
|
||||
**File:** `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.VexBridge/VexEvidenceGenerator.cs`
|
||||
|
||||
Core logic:
|
||||
1. Map `FixState` to `VexClaimStatus` (fixed→not_affected, vulnerable→affected)
|
||||
2. Construct evidence JSONB with fingerprint metadata
|
||||
3. Generate deterministic observation ID: `uuid5(namespace, tenant+cve+product+scan)`
|
||||
4. Apply DSSE signing if enabled
|
||||
5. Return `VexObservation` ready for Excititor persistence
|
||||
|
||||
### D3: Evidence Schema for Binary Matches
|
||||
**Evidence JSONB Structure:**
|
||||
```json
|
||||
{
|
||||
"type": "binary_fingerprint_match",
|
||||
"match_type": "build_id|fingerprint|hash_exact",
|
||||
"build_id": "abc123def456...",
|
||||
"file_sha256": "sha256:...",
|
||||
"text_sha256": "sha256:...",
|
||||
"fingerprint_algorithm": "combined",
|
||||
"similarity": 0.97,
|
||||
"distro_release": "debian:bookworm",
|
||||
"source_package": "openssl",
|
||||
"fixed_version": "3.0.7-1+deb12u1",
|
||||
"fix_method": "patch_header",
|
||||
"fix_confidence": 0.90,
|
||||
"evidence_ref": "fix_evidence:uuid"
|
||||
}
|
||||
```
|
||||
|
||||
### D4: DI Registration
|
||||
**File:** `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.VexBridge/ServiceCollectionExtensions.cs`
|
||||
|
||||
```csharp
|
||||
public static IServiceCollection AddBinaryVexBridge(
|
||||
this IServiceCollection services,
|
||||
IConfiguration configuration)
|
||||
{
|
||||
services.AddSingleton<IVexEvidenceGenerator, VexEvidenceGenerator>();
|
||||
services.Configure<VexBridgeOptions>(configuration.GetSection("VexBridge"));
|
||||
return services;
|
||||
}
|
||||
```
|
||||
|
||||
### D5: Unit Tests
|
||||
**File:** `src/BinaryIndex/__Tests/StellaOps.BinaryIndex.VexBridge.Tests/VexEvidenceGeneratorTests.cs`
|
||||
|
||||

- Fixed binary → `not_affected` with `vulnerable_code_not_present` justification
|
||||
- Vulnerable binary → `affected` status
|
||||
- Unknown fix status → `under_investigation`
|
||||
- Batch generation preserves ordering
|
||||
- Evidence JSONB contains all required fields
|
||||
- Deterministic observation ID generation

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Use uuid5 for observation IDs | Determinism for replay; avoids random UUIDs |
|
||||
| Separate library (not in Core) | Avoids circular deps with Excititor |
|
||||
| Evidence as JSONB not typed | Flexibility for future evidence types |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Excititor API changes | Depend on stable contracts only |
|
||||
| Signing key availability | Fallback to unsigned with warning |
|
||||
| ~~BLOCKER: Excititor.Core circular dependency~~ | **RESOLVED 2025-12-28**: Extracted DSSE types to `StellaOps.Excititor.Core.Dsse`. Attestation re-exports via global using. |
|
||||
| ~~BLOCKER: StellaOps.Policy JsonPointer struct issue~~ | **RESOLVED 2025-12-28**: Fixed by removing `?.` operator from struct types in Policy library. |

| 2025-12-27 | Created VexBridge.Tests project with comprehensive unit tests for status mapping, batch processing, and evidence generation | Implementer |
|
||||
| 2025-12-28 | Build validation: VexBridge code syntax-verified, but blocked by pre-existing Excititor.Core circular dependency. Removed unavailable System.ComponentModel.Annotations 6.0.0 from Contracts.csproj. Updated Excititor.Core to add missing Caching/Configuration packages. | Implementer |
|
||||
| 2025-12-28 | **UNBLOCKED**: Fixed circular dependency by extracting DSSE types to `StellaOps.Excititor.Core.Dsse` namespace. Fixed ProductionVexSignatureVerifier API calls and missing package refs. Excititor.Core now builds successfully. | Agent |

| **Module** | BE (Backend) |
|

|
||||
|
||||
## Objective
|
||||
|
||||
Expose a high-performance `/api/v1/resolve/vuln` endpoint that accepts binary identity data and returns resolution status with evidence. Implement Valkey caching for sub-millisecond lookups on repeated queries.
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `IBinaryVulnerabilityService` provides all lookup methods but requires direct service injection
|
||||
- No HTTP API for external callers (Scanner.Worker, CLI, third-party integrations)
|
||||
- Fix status caching exists (`CachedBinaryVulnerabilityService`) but fingerprint resolution doesn't
|
||||
|
||||
### Target State
|
||||
- REST API: `POST /api/v1/resolve/vuln` with batch support
|
||||
- Valkey cache: `fingerprint:{hash} → {status, evidence_ref, expires}`
|
||||
- Response includes DSSE envelope for attestable proofs
|
||||
- OpenAPI spec with full schema documentation
|
||||
|
||||

}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Cache Strategy
|
||||
|
||||
### TTL Configuration
|
||||
| Scenario | TTL |
|
||||
|----------|-----|
|
||||
| Fixed (high confidence) | 24 hours |
|
||||
| Vulnerable | 4 hours |
|
||||
| Unknown | 1 hour |
|
||||
| After corpus update | Invalidate by distro pattern |
|
||||
|
||||
### Invalidation Triggers
|
||||
- Corpus snapshot ingested: `InvalidateByPatternAsync("resolution:*:{distro}:*")`
|
||||
- Manual override: API endpoint for admin invalidation
|
||||
- Version bump: Include corpus version in cache key
|
||||
|
||||
---
|
||||
|
||||
## Telemetry
|
||||
|
||||
### Metrics
|
||||
- `binaryindex_resolution_requests_total{status, method, cache_hit}`
|
||||
- `binaryindex_resolution_latency_seconds{quantile}`
|
||||
- `binaryindex_cache_hit_ratio`
|
||||
- `binaryindex_fingerprint_matches_total{algorithm, confidence_tier}`
|
||||
|
||||
### Traces
|
||||
- Span: `ResolutionService.ResolveAsync`
|
||||
- Attributes: package, match_type, cache_hit, confidence
|
||||
|
||||

|
||||
4. [ ] DSSE attestation verifiable with standard tools
|
||||
5. [ ] OpenAPI spec generates valid client SDKs
|
||||
6. [ ] Cache invalidation clears stale entries

## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Valkey over Redis | OSS-friendly, drop-in compatible |
|
||||
| POST for single resolution | Body allows complex identity objects |
|
||||
| DSSE optional in response | Performance for high-volume callers |
|
||||
| Cache key includes CVE | Targeted invalidation per vulnerability |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Cache stampede on corpus update | Probabilistic early expiry |
|
||||
| Valkey unavailability | Fallback to direct DB query |
|
||||
| Large batch payloads | Limit batch size to 500 |
|
||||
| ~~BLOCKER: Excititor.Core build errors~~ | **RESOLVED 2025-12-28**: Fixed circular dependency and API issues in Excititor.Core |

| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0002_0001 |
|
||||
| **Batch** | 002 - Corpus Seeding |
|
||||
| **Module** | LB (Library) |
|
||||
| **Topic** | Reproducible patch builders + function CVE mapping |
|
||||
| **Priority** | P1 - High Value |
|
||||
| **Estimated Effort** | High |
|
||||
| **Dependencies** | SPRINT_1227_0001_0001, SPRINT_1227_0001_0002 |
|
||||
| **Working Directory** | `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Builders/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Implement automated reproducible build pipeline for distro packages that:
|
||||
1. Fetches source packages (SRPM, Debian source, Alpine APKBUILD)
|
||||
2. Applies security patches
|
||||
3. Builds with deterministic settings
|
||||
4. Extracts function-level fingerprints with CVE fix attribution
|
||||
5. Populates `fingerprint_claims` table with per-function evidence
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- Corpus connectors download **pre-built packages** from distro mirrors
|
||||
- Fingerprints generated from downloaded binaries
|
||||
- No patch-to-function mapping exists
|
||||
- Cannot attribute "this function contains fix for CVE-XYZ"
|
||||
|
||||
### Target State
|
||||
- Build vulnerable version → extract fingerprints
|
||||
- Apply patches → rebuild → extract fingerprints
|
||||
- Diff fingerprints → identify changed functions
|
||||
- Create `fingerprint_claims` with CVE attribution
|
||||
- Support Alpine, Debian, RHEL (Phase 1)
|
||||
|
||||

|
||||
|
||||
## Deliverables
|
||||
|
||||
### D1: Reproducible Build Container Specs

- Strip `__DATE__`, `__TIME__` macros
|
||||
- Normalize build paths (`/build/` prefix)
|
||||
- Reproducible ar/tar ordering

|
||||
|
||||
## High-Value Library Targets (Phase 1)
|
||||
|
||||
| Library | Rationale |
|
||||
|---------|-----------|
|
||||
| openssl | Most CVEs, critical for TLS |
|
||||
| glibc | Core runtime, common backports |
|
||||
| curl | Network-facing, frequent patches |
|
||||
| zlib | Compression, wide usage |
|
||||
| sqlite | Embedded database, common |
|
||||
| libxml2 | XML parsing, security-sensitive |
|
||||
| expat | XML parsing, CVE-prone |
|
||||
| busybox | Alpine core, many tools |
|
||||
|
||||
---
|
||||
|
||||
## Normalization Checklist
|
||||
|
||||
### Compiler Flags
|
||||
```bash
|
||||
CFLAGS="-fno-record-gcc-switches -fdebug-prefix-map=$(pwd)=/build"
|
||||
CXXFLAGS="${CFLAGS}"
|
||||
```
|
||||
|
||||
### Environment
|
||||
```bash
|
||||
export TZ=UTC
|
||||
export LC_ALL=C.UTF-8
|
||||
export SOURCE_DATE_EPOCH=... # From changelog or git
|
||||
```
|
||||
|
||||
### Archive Ordering
|
||||
```bash
|
||||
# Deterministic ar
|
||||
ar --enable-deterministic-archives
|
||||
|
||||
# Sorted tar
|
||||
tar --sort=name --mtime="@${SOURCE_DATE_EPOCH}" --owner=0 --group=0
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
1. [ ] Alpine builder produces reproducible binaries (bit-for-bit)
|
||||
2. [ ] Debian builder produces reproducible binaries
|
||||
3. [ ] RHEL builder produces reproducible binaries (mock-based)
|
||||
4. [ ] Function fingerprints extracted with < 5% false positive rate
|
||||
5. [ ] Patch diff correctly identifies changed functions
|
||||
6. [ ] `fingerprint_claims` populated with correct CVE attribution
|
||||
7. [ ] End-to-end: advisory → build → fingerprint → claim in < 1 hour
|
||||
8. [ ] Test coverage for openssl, curl, zlib samples
|
||||
|
||||
---
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Container-based builds | Isolation, reproducibility, parallelization |
|
||||
| objdump for function extraction | Reliable, works on stripped binaries |
|
||||
| Focus on 8 high-value libs first | 80/20 - cover most CVE volume |
|
||||
| Store function fingerprints separately | Query flexibility, join performance |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Reproducibility failures | Per-distro normalization; track reproducibility rate |
|
||||
| Build time (hours per package) | Parallelize; cache intermediate artifacts |
|
||||
| Compiler version drift | Pin toolchains per distro release |
|
||||
| Function matching ambiguity | Use 3-algorithm ensemble; confidence thresholds |
|
||||

## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Material Design components | Consistent with existing UI |
|
||||
| Drawer vs. modal for evidence | Better for multi-section content |
|
||||
| Disasm syntax highlighting | Monaco editor (already bundled) |
|
||||
| Lazy load diff viewer | Heavy component, rarely used |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Large DSSE envelopes | Truncate display, full copy |
|
||||
| Disasm not available | Show "Binary analysis only" message |
|
||||
| Slow Rekor lookups | Cache verification results |
|
||||

# Sprint: Activate VEX Signature Verification Pipeline
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0004_0001 |
|
||||
| **Batch** | 001 - Activate Verification |
|
||||
| **Module** | BE (Backend) |
|
||||
| **Topic** | Replace NoopVexSignatureVerifier with real verification |
|
||||
| **Priority** | P0 - Critical Path |
|
||||
| **Estimated Effort** | Medium |
|
||||
| **Dependencies** | Attestor.Verify, Cryptography, IssuerDirectory |
|
||||
| **Working Directory** | `src/Excititor/__Libraries/StellaOps.Excititor.Core/Verification/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Replace `NoopVexSignatureVerifier` with a production-ready implementation that:
|
||||
1. Verifies DSSE/in-toto signatures on VEX documents
|
||||
2. Validates key provenance against IssuerDirectory
|
||||
3. Checks certificate chains for keyless attestations
|
||||
4. Supports all crypto profiles (FIPS, eIDAS, GOST, SM)
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `NoopVexSignatureVerifier` always returns `verified: true`
|
||||
- `AttestorVerificationEngine` has full verification logic but isn't wired to VEX ingest
|
||||
- `IssuerDirectory` stores issuer keys with validity windows and revocation status
|
||||
- Signature metadata captured at ingest but not validated
|
||||
|
||||
### Target State
|
||||
- All VEX documents with signatures are cryptographically verified
|
||||
- Invalid signatures marked `verified: false` with reason
|
||||
- Key provenance checked against IssuerDirectory
|
||||
- Verification results cached in Valkey for performance
|
||||
- Offline mode uses bundled trust anchors
|
||||

### D2: ProductionVexSignatureVerifier Implementation
|
||||
**File:** `src/Excititor/__Libraries/StellaOps.Excititor.Core/Verification/ProductionVexSignatureVerifier.cs`
|
||||
|
||||
Core logic:
|
||||
1. Extract signature metadata from document
|
||||
2. Determine verification method (DSSE, cosign, PGP, x509)
|
||||
3. Look up issuer in IssuerDirectory
|
||||
4. Get signing key or certificate chain
|
||||
5. Verify signature using appropriate crypto provider
|
||||
6. Check key validity (not_before, not_after, revocation)
|
||||
7. Return structured result with diagnostics
|
||||
|
||||
```csharp
|
||||
public sealed class ProductionVexSignatureVerifier : IVexSignatureVerifier
|
||||
{
|
||||
private readonly IIssuerDirectoryClient _issuerDirectory;
|
||||
private readonly ICryptoProviderRegistry _cryptoProviders;
|
||||
private readonly IAttestorVerificationEngine _attestorEngine;
|
||||
private readonly IVerificationCacheService _cache;
|
||||
private readonly VexSignatureVerifierOptions _options;
|
||||
|
||||
public async Task<VexSignatureVerificationResult> VerifyAsync(
|
||||
VexRawDocument document,
|
||||
VexVerificationContext context,
|
||||
CancellationToken ct)
|
||||
{
|
||||
// 1. Check cache
|
||||
var cacheKey = $"vex-sig:{document.Digest}:{context.Profile}";
|
||||
if (await _cache.TryGetAsync(cacheKey, out var cached))
|
||||
return cached with { VerifiedAt = DateTimeOffset.UtcNow };
|
||||
|
||||
// 2. Extract signature info
|
||||
var sigInfo = ExtractSignatureInfo(document);
|
||||
if (sigInfo is null)
|
||||
return NoSignatureResult(document.Digest);
|
||||
|
||||
// 3. Lookup issuer
|
||||
var issuer = await _issuerDirectory.GetIssuerByKeyIdAsync(
|
||||
sigInfo.KeyId, context.TenantId, ct);
|
||||
|
||||
// 4. Select verification strategy
|
||||
var result = sigInfo.Method switch
|
||||
{
|
||||
VerificationMethod.Dsse => await VerifyDsseAsync(document, sigInfo, issuer, context, ct),
|
||||
VerificationMethod.DsseKeyless => await VerifyDsseKeylessAsync(document, sigInfo, context, ct),
|
||||
VerificationMethod.Cosign => await VerifyCosignAsync(document, sigInfo, issuer, context, ct),

|
||||
### D3: Crypto Profile Selection
|
||||
**File:** `src/Excititor/__Libraries/StellaOps.Excititor.Core/Verification/CryptoProfileSelector.cs`
|
||||
|
||||
Select appropriate crypto profile based on:
|
||||
- Issuer metadata (jurisdiction field)
|
||||
- Tenant configuration
|
||||
- Document metadata hints
|
||||
- Fallback to World profile
|
||||
|
||||
### D4: Verification Cache Service
|
||||
**File:** `src/Excititor/__Libraries/StellaOps.Excititor.Cache/VerificationCacheService.cs`
|
||||
|
||||
```csharp
|
||||
public interface IVerificationCacheService
|
||||
{
|
||||
Task<bool> TryGetAsync(string key, out VexSignatureVerificationResult? result);
|
||||
Task SetAsync(string key, VexSignatureVerificationResult result, TimeSpan ttl, CancellationToken ct);
|
||||
Task InvalidateByIssuerAsync(string issuerId, CancellationToken ct);
|
||||
}
|
||||
```
|
||||
|
||||
Valkey-backed with:
|
||||
- Key format: `vex-sig:{document_digest}:{crypto_profile}`
|
||||
- TTL: Configurable (default 4 hours)
|
||||
- Invalidation on key revocation events
|
||||
|
||||
### D5: IssuerDirectory Client Integration
|
||||
**File:** `src/Excititor/__Libraries/StellaOps.Excititor.Core/Clients/IIssuerDirectoryClient.cs`
|
||||
|
||||
```csharp
|
||||
public interface IIssuerDirectoryClient
|
||||
{
|
||||
Task<IssuerInfo?> GetIssuerByKeyIdAsync(string keyId, string tenantId, CancellationToken ct);
|
||||
Task<IssuerKey?> GetKeyAsync(string issuerId, string keyId, CancellationToken ct);
|
||||
Task<bool> IsKeyRevokedAsync(string keyId, CancellationToken ct);
|
||||
Task<IReadOnlyList<IssuerKey>> GetActiveKeysForIssuerAsync(string issuerId, CancellationToken ct);
|
||||
}
|
||||
```
|
||||
|
||||
### D6: DI Registration & Feature Flag
|
||||
**File:** `src/Excititor/StellaOps.Excititor.WebService/Program.cs`
|
||||
|
||||
```csharp
|
||||
if (configuration.GetValue<bool>("VexSignatureVerification:Enabled", false))
|
||||
{
|
||||
services.AddSingleton<IVexSignatureVerifier, ProductionVexSignatureVerifier>();
|
||||
}
|
||||
else
|
||||
{
|
||||
services.AddSingleton<IVexSignatureVerifier, NoopVexSignatureVerifier>();
|
||||
}
|
||||
```
|
||||
|
||||
### D7: Configuration
|
||||
**File:** `etc/excititor.yaml.sample`
|
||||
|
||||
```yaml
|
||||
VexSignatureVerification:
|
||||
Enabled: true
|
||||
DefaultProfile: "world"
|
||||
RequireSignature: false # If true, reject unsigned documents
|
||||
AllowExpiredCerts: false
|
||||
CacheTtl: "4h"
|
||||
IssuerDirectory:
|
||||
ServiceUrl: "https://issuer-directory.internal/api"
|
||||
Timeout: "5s"
|
||||
OfflineBundle: "/var/stellaops/bundles/issuers.json"
|
||||

|
||||
Fulcio:
|
||||
- "/var/stellaops/trust/fulcio-root.pem"
|
||||

|
||||
- "/var/stellaops/trust/sigstore-root.pem"
|
||||
```
|
||||
|
||||
### D8: Unit & Integration Tests
|
||||
**Files:**
|
||||
- `src/Excititor/__Tests/StellaOps.Excititor.Core.Tests/Verification/ProductionVexSignatureVerifierTests.cs`
|
||||
- `src/Excititor/__Tests/StellaOps.Excititor.WebService.Tests/VerificationIntegrationTests.cs`
|
||||
|
||||
Test cases:
|
||||
- Valid DSSE signature → verified: true
|
||||
- Invalid signature → verified: false, reason: InvalidSignature
|
||||
- Expired certificate → verified: false, reason: ExpiredCertificate
|
||||
- Revoked key → verified: false, reason: RevokedCertificate
|
||||
- Unknown issuer → verified: false, reason: UnknownIssuer
|
||||
- Keyless with valid chain → verified: true
|
||||
- Cache hit returns cached result
|
||||
- Batch verification performance (1000 docs < 5s)
|
||||
- Profile selection based on jurisdiction

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Feature flag default OFF | Non-breaking rollout |
|
||||
| Cache by document digest + profile | Different profiles may have different outcomes |
|
||||
| Fail open if IssuerDirectory unavailable | Availability over security (configurable) |
|
||||
| No signature = warning, not failure | Many legacy VEX docs unsigned |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Performance regression on ingest | Cache aggressively; batch verification |
|
||||
| Trust anchor freshness | Auto-refresh from Sigstore TUF |
|
||||
| Clock skew affecting validity | Use configured tolerance (default 5min) |
|

| **Sprint ID** | SPRINT_1227_0004_0003 |
|
||||
| **Batch** | 003 - Policy Gates |
|
||||
| **Module** | BE (Backend) |
|

| **Topic** | VexTrustGate for policy enforcement |
|

| **Priority** | P1 - Control |
|

|
||||
|
||||
## Objective
|
||||
|
||||
Implement `VexTrustGate` as a new policy gate that:
|
||||
1. Enforces minimum trust thresholds per environment
|
||||
2. Blocks status transitions when trust is insufficient
|
||||
3. Adds VEX trust as a factor in confidence scoring
|
||||
4. Supports tenant-specific threshold overrides
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- Policy gate chain: EvidenceCompleteness → LatticeState → UncertaintyTier → Confidence
|
||||
- `ConfidenceFactorType.Vex` exists but not populated with trust data
|
||||
- `VexTrustStatus` available in `FindingGatingStatus` model
|
||||
- `MinimumConfidenceGate` provides pattern for threshold enforcement
|
||||
|
||||
### Target State
|
||||
- `VexTrustGate` added to policy gate chain (after LatticeState)
|
||||
- Trust score contributes to confidence calculation
|
||||
- Per-environment thresholds (production stricter than staging)
|
||||
- Block/Warn/Allow based on trust level
|
||||
- Audit trail includes trust decision rationale

||||

public sealed class PolicyAuditEntity
|
||||
{
|
||||
// ... existing fields ...
|
||||
|
||||
// NEW: VEX trust audit data
|
||||
public decimal? VexTrustScore { get; set; }
|
||||
public string? VexTrustTier { get; set; }
|
||||
public bool? VexSignatureVerified { get; set; }
|
||||
public string? VexIssuerId { get; set; }
|
||||
public string? VexIssuerName { get; set; }
|
||||
public string? VexTrustGateResult { get; set; }
|
||||
public string? VexTrustGateReason { get; set; }
|
||||
}
|
||||
```
|
||||
|
||||
### D8: Unit & Integration Tests
|
||||
**Files:**
|
||||
- `src/Policy/__Tests/StellaOps.Policy.Engine.Tests/Gates/VexTrustGateTests.cs`
|
||||
- `src/Policy/__Tests/StellaOps.Policy.Gateway.Tests/VexTrustGateIntegrationTests.cs`
|
||||
|
||||
Test cases:
|
||||
- High trust + production → Allow
|
||||
- Low trust + production → Block
|
||||
- Medium trust + staging → Warn
|
||||
- Missing trust data + Warn behavior → Warn
|
||||
- Missing trust data + Block behavior → Block
|
||||
- Signature not verified + RequireIssuerVerified → Block
|
||||
- Stale freshness + production → Block
|
||||
- Confidence factor correctly aggregated
|
||||
- Audit trail includes trust details

||||
|
||||
## Acceptance Criteria

|
||||
3. [ ] Per-environment thresholds configurable
|
||||
4. [ ] VEX trust contributes to confidence score
|
||||
5. [ ] Audit trail records trust decision details
|
||||
6. [ ] Feature flag allows gradual rollout
|
||||
7. [ ] Missing trust handled according to config
|
||||
8. [ ] Metrics exposed for monitoring
|
||||
9. [ ] Unit test coverage > 90%
|
||||
|
||||

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Feature flag default OFF | Non-breaking rollout to existing tenants |
|
||||
| Order 250 (after LatticeState) | Trust validation after basic lattice checks |
|
||||
| Block only in production | Progressive enforcement; staging gets warnings |
|
||||
| Trust factor weight 0.20 | Balanced with other factors (reachability 0.30, provenance 0.25) |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| VexLens unavailable | Fallback to cached trust scores |
|
||||
| Performance regression | Cache trust scores with TTL |
|
||||
| Threshold tuning needed | Shadow mode logging before enforcement |
|
||||
|
||||
---
|
||||
|
||||
## Rollout Plan
|
||||
|
||||
1. **Phase 1 (Feature Flag):** Deploy with `Enabled: false`
|
||||
2. **Phase 2 (Shadow Mode):** Enable with `FailureAction: Warn` everywhere
|
||||
3. **Phase 3 (Analyze):** Review warn logs, tune thresholds
|
||||
4. **Phase 4 (Production Enforcement):** Set `FailureAction: Block` for production
|
||||
5. **Phase 5 (Full Rollout):** Enable for all tenants

# Sprint: Signed TrustVerdict Attestations
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0004_0004 |
|
||||
| **Batch** | 004 - Attestations & Cache |
|
||||
| **Module** | LB (Library) |
|
||||
| **Topic** | Signed TrustVerdict for deterministic replay |
|
||||
| **Priority** | P1 - Audit |
|
||||
| **Estimated Effort** | Medium |
|
||||
| **Dependencies** | SPRINT_1227_0004_0001, SPRINT_1227_0004_0003 |
|
||||
| **Working Directory** | `src/Attestor/__Libraries/StellaOps.Attestor.TrustVerdict/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Create signed `TrustVerdict` attestations that:
|
||||
1. Bundle verification results with evidence chain
|
||||
2. Are DSSE-signed for non-repudiation
|
||||
3. Can be OCI-attached for distribution
|
||||
4. Support deterministic replay (same inputs → same verdict)
|
||||
5. Are Valkey-cached for performance
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- `AttestorVerificationEngine` verifies signatures but doesn't produce attestations
|
||||
- DSSE infrastructure complete (`DsseEnvelope`, `EnvelopeSignatureService`)
|
||||
- OCI attachment patterns exist in Signer module
|
||||
- Valkey cache infrastructure available
|
||||
- No `TrustVerdict` predicate type defined
|
||||
|
||||
### Target State
|
||||
- `TrustVerdictPredicate` in-toto predicate type
|
||||
- `TrustVerdictService` generates signed verdicts
|
||||
- OCI attachment for distribution with images
|
||||
- Valkey cache for fast lookups
|
||||
- Deterministic outputs for replay

||||

|
||||
|
||||
## Determinism Requirements
|
||||
|
||||
### Canonical Serialization
|
||||
- UTF-8 without BOM
|
||||
- Sorted keys (ASCII order)
|
||||
- No insignificant whitespace
|
||||
- Timestamps in ISO-8601 UTC (`YYYY-MM-DDTHH:mm:ssZ`)
|
||||
- Numbers without trailing zeros
|
||||
|
||||
### Verdict Digest Computation
|
||||
```csharp
|
||||
var canonical = CanonicalJsonSerializer.Serialize(predicate);
|
||||
var digest = SHA256.HashData(Encoding.UTF8.GetBytes(canonical));
|
||||
return $"sha256:{Convert.ToHexStringLower(digest)}";
|
||||
```
|
||||
|
||||
### Evidence Ordering
|
||||
- Items sorted by digest ascending
|
||||
- Merkle tree built deterministically (power-of-2 padding)
|
||||
|
||||

## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Predicate URI `stellaops.dev/predicates/trust-verdict@v1` | Namespace for StellaOps-specific predicates |
|
||||
| Merkle tree for evidence | Compact proof, standard crypto pattern |
|
||||
| Valkey cache with TTL | Balance freshness vs performance |
|
||||
| Optional Rekor/OCI | Support offline deployments |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Rekor availability | Optional; skip with warning |
|
||||
| OCI registry compatibility | Use standard ORAS patterns |
|
||||
| Large verdict size | Compress DSSE payload |

# Sprint 1227.0012.0001 - ReachGraph Core Library & Schema
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Implement the **ReachGraph Core Library** providing a unified data model and storage for reachability subgraphs. This sprint establishes the foundation for fast, deterministic, audit-ready answers to "*exactly why* a dependency is reachable."
|
||||
|
||||
This sprint delivers:
|
||||
- Unified ReachGraph schema extending PoE predicate format
|
||||
- Edge explainability vocabulary (import, dynamic load, feature flags, guards)
|
||||
- Content-addressed storage with BLAKE3 hashing
|
||||
- DSSE signing integration via Attestor
|
||||
- PostgreSQL persistence layer
|
||||
- Valkey cache for hot subgraph slices
|
||||
|
||||
**Working directory:** `src/__Libraries/StellaOps.ReachGraph/`
|
||||
|
||||
**Cross-module touchpoints:**
|
||||
- `src/Attestor/` - DSSE signing, PoE predicate compatibility
|
||||
- `src/Scanner/` - Call graph extraction (upstream producer)
|
||||
- `src/Signals/` - Runtime facts correlation (upstream producer)
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream**: PoE predicate (Sprint 3500.0001.0001) - COMPLETED
|
||||
- **Downstream**: Sprint 1227.0012.0002 (ReachGraph Store APIs)
|
||||
- **Safe to parallelize with**: None (foundational library)
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- `src/Attestor/POE_PREDICATE_SPEC.md`
|
||||

## Wave Coordination
|
||||
|
||||
**Single wave with sequential dependencies:**
|
||||
1. Schema design (T1-T3)
|
||||
2. Serialization (T4-T5)
|
||||
3. Provenance & signing (T6-T7)
|
||||
4. Persistence (T8-T9)
|
||||
5. Testing (T10)
|
||||
|
||||

|
||||
|
||||
## Section 1: Architecture Overview
|
||||
|
||||
### 1.1 High-Level Design
|
||||
|
||||
```
|
||||
Scanner.CallGraph ─┐
|
||||
├─> ReachGraph Store ─> Policy Engine
|
||||
Signals.Reachability┘ │ │
|
||||
▼ ▼
|
||||
PostgreSQL Valkey Cache
|
||||
│ │
|
||||
└───────────┘
|
||||
│
|
||||
▼
|
||||
Web Console / CLI
|
||||
```
|
||||
|
||||
### 1.2 Key Design Principles
|
||||
|
||||
1. **Determinism**: Same inputs produce identical digests
|
||||
2. **PoE Compatibility**: ReachGraph is superset of PoE subgraph schema
|
||||
3. **Edge Explainability**: Every edge carries "why" metadata
|
||||
4. **Content Addressing**: All artifacts identified by BLAKE3 hash
|
||||
5. **Offline-First**: Signed artifacts verifiable without network
|
||||
|
||||
### 1.3 Relationship to Existing Modules
|
||||
|
||||
| Module | Integration Point | Data Flow |
|
||||
|--------|------------------|-----------|
|
||||
| Scanner.CallGraph | `CallGraphSnapshot` | Produces nodes/edges |
|
||||
| Signals | `ReachabilityFactDocument` | Runtime confirmation |
|
||||
| Attestor | `DsseEnvelope`, PoE predicate | Signing, schema basis |
|
||||
| Policy | `REACHABLE` atom, gates | Consumes for decisions |
|
||||
| Graph | `NodeTile`, `EdgeTile` | Visualization queries |

|
||||
### T4: Deterministic JSON Serialization
|
||||
|
||||
**File:** `src/__Libraries/StellaOps.ReachGraph/Serialization/CanonicalReachGraphSerializer.cs`
|
||||
|
||||
**Requirements:**
|
||||
1. Lexicographically sorted object keys
|
||||
2. Arrays sorted by deterministic field:
|
||||
- Nodes by `Id`
|
||||
- Edges by `From`, then `To`
|
||||
- Signatures by `KeyId`
|
||||
3. UTC ISO-8601 timestamps with millisecond precision
|
||||
4. No null fields (omit when null)
|
||||
5. Minified output for `reachgraph.min.json`
|
||||
6. Prettified option for debugging
|
||||
|
||||
**Key Methods:**
|
||||
```csharp
|
||||
public sealed class CanonicalReachGraphSerializer
|
||||
{
|
||||
/// <summary>Serialize to canonical minified JSON bytes.</summary>
|
||||
public byte[] SerializeMinimal(ReachGraphMinimal graph);
|
||||
|
||||
/// <summary>Serialize to canonical prettified JSON for debugging.</summary>
|
||||
public string SerializePretty(ReachGraphMinimal graph);
|
||||
|
||||
/// <summary>Deserialize from JSON bytes.</summary>
|
||||
public ReachGraphMinimal Deserialize(ReadOnlySpan<byte> json);

### T10: Test Suite
|
||||
|
||||
**File:** `src/__Libraries/__Tests/StellaOps.ReachGraph.Tests/`
|
||||
|
||||
**Test Files:**
|
||||
1. `CanonicalSerializerTests.cs` - Deterministic serialization
|
||||
2. `DigestComputerTests.cs` - BLAKE3 hashing
|
||||
3. `EdgeExplanationTests.cs` - Explanation type coverage
|
||||
4. `GoldenSampleTests.cs` - Fixture-based verification
|
||||
5. `RoundtripTests.cs` - Serialize/deserialize parity
|
||||
|
||||
**Golden Samples:**
|
||||
```
|
||||

|
||||

|
||||
└── large-graph-50-nodes.reachgraph.min.json
|
||||
```
|
||||
|
||||
**Key Test Cases:**
|
||||
```csharp
|
||||
[Fact]
|
||||
public void Serialization_WithSameInput_ProducesSameDigest()
|
||||
{
|
||||
var graph = CreateSampleGraph();
|
||||
var digest1 = _digestComputer.ComputeDigest(graph);
|
||||
var digest2 = _digestComputer.ComputeDigest(graph);
|
||||
|
||||
Assert.Equal(digest1, digest2);
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void Serialization_NodeOrder_IsLexicographic()
|
||||
{
|
||||
var graph = CreateGraphWithUnorderedNodes();
|
||||
var json = _serializer.SerializePretty(graph);
|
||||
var deserialized = _serializer.Deserialize(Encoding.UTF8.GetBytes(json));
|
||||
|
||||
Assert.True(IsLexicographicallySorted(deserialized.Nodes, n => n.Id));
|
||||
}
|
||||
|
||||
[Theory]
|
||||
[MemberData(nameof(GoldenSamples))]
|
||||
public void GoldenSample_Digest_Matches(string fixturePath, string expectedDigest)
|
||||
{
|
||||
var json = File.ReadAllBytes(fixturePath);
|
||||
var graph = _serializer.Deserialize(json);
|
||||
var digest = _digestComputer.ComputeDigest(graph);
|
||||
|
||||
Assert.Equal(expectedDigest, digest);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
1. **BLAKE3 over SHA-256**: Faster hashing with same security level
|
||||
2. **Minified default**: `reachgraph.min.json` is minified; prettified available for debugging
|
||||
3. **PoE superset**: ReachGraph schema is compatible superset of PoE subgraph
|
||||
4. **Gzip compression**: Stored blobs are gzip compressed for space efficiency
|
||||
5. **Tenant isolation**: RLS enforced at PostgreSQL level
|
||||
|
||||
### Risks
|
||||
1. **Schema drift**: PoE and ReachGraph could diverge
|
||||
- **Mitigation**: Define ReachGraph as extension of PoE; maintain compatibility tests
|
||||
2. **Large graphs**: Very large graphs could exceed cache limits
|
||||
- **Mitigation**: MaxGraphSizeBytes limit; slice caching for hot queries
|
||||
3. **Determinism violations**: Edge cases in serialization could break determinism
|
||||
- **Mitigation**: Comprehensive golden sample tests; fuzzing
|
||||
|
||||

||||

# Sprint 1227.0012.0002 - ReachGraph Store APIs & Slice Queries
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Implement the **ReachGraph Store Web Service** providing REST APIs for storing, querying, and replaying reachability subgraphs. This sprint delivers the query layer enabling fast "why reachable?" answers.
|
||||
|
||||
This sprint delivers:
|
||||
- `POST /v1/reachgraphs` - Upsert subgraph by digest
|
||||
- `GET /v1/reachgraphs/{digest}` - Retrieve full subgraph
|
||||
- Slice query APIs (by package, CVE, entrypoint, file)
|
||||
- `POST /v1/reachgraphs/replay` - Deterministic replay verification
|
||||
- OpenAPI specification with examples
|
||||
- Rate limiting and tenant isolation
|
||||
|
||||
**Working directory:** `src/ReachGraph/StellaOps.ReachGraph.WebService/`
|
||||
|
||||
**Cross-module touchpoints:**
|
||||
- `src/__Libraries/StellaOps.ReachGraph/` - Core library (Sprint 1)
|
||||
- `src/Authority/` - Authentication/authorization
|
||||
- `src/Attestor/` - DSSE verification
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream**: Sprint 1227.0012.0001 (ReachGraph Core Library) - REQUIRED
|
||||
- **Downstream**: Sprint 1227.0012.0003 (Extractors, Policy Integration & UI)
|
||||
- **Safe to parallelize with**: None (depends on Sprint 1)
|
||||
|
||||
## Documentation Prerequisites
|
||||
|
||||
- Sprint 1227.0012.0001 schema documentation
|
||||
- `docs/modules/attestor/architecture.md`
|

## Section 1: Service Architecture
|
||||
|
||||
### 1.1 Endpoint Summary
|
||||
|
||||
| Method | Path | Description |
|
||||
|--------|------|-------------|
|
||||
| POST | `/v1/reachgraphs` | Upsert subgraph (idempotent by digest) |
|
||||
| GET | `/v1/reachgraphs/{digest}` | Retrieve full subgraph |
|
||||
| GET | `/v1/reachgraphs/{digest}/slice` | Query sliced subgraph |
|
||||
| POST | `/v1/reachgraphs/replay` | Verify determinism |
|
||||
| GET | `/v1/reachgraphs/by-artifact/{artifactDigest}` | List subgraphs for artifact |
|
||||
| DELETE | `/v1/reachgraphs/{digest}` | Soft-delete (admin only) |
|
||||
|
||||
### 1.2 Authentication & Authorization
|
||||
|
||||
- **Required scope**: `reachgraph:read`, `reachgraph:write`
|
||||
- **Tenant isolation**: Via RLS and `X-Tenant-ID` header
|
||||
- **Rate limiting**: 100 req/min for reads, 20 req/min for writes
|
||||
|
||||

|
||||
|
||||
## Section 2: Upsert Endpoint
|
||||
|
||||
### T1: POST /v1/reachgraphs
|
||||
|
||||
**Request:**
|
||||
```http
|
||||
POST /v1/reachgraphs
|
||||
Content-Type: application/json
|
||||
Authorization: Bearer <token>
|
||||
X-Tenant-ID: acme-corp
|
||||
|
||||
{
|
||||
"graph": { ... ReachGraphMinimal ... }
|
||||
}
|
||||
```
|
||||
|
||||
**Response (201 Created / 200 OK):**
|
||||
```json
|
||||
{
|
||||
"digest": "blake3:a1b2c3d4...",
|
||||
"created": true,
|
||||
"artifactDigest": "sha256:...",
|
||||
"nodeCount": 15,
|
||||
"edgeCount": 22,
|
||||
"storedAt": "2025-12-27T10:00:00Z"
|
||||
}
|
||||
```
|
||||
|
||||
**Idempotency:**
|
||||
- If digest already exists, return 200 OK (not 201)
|
||||
- Content must match - reject if different content produces same digest (hash collision defense)
|
||||
|
||||
**Validation:**
|
||||
- Schema validation against ReachGraphMinimal
|
||||
- Signature verification if signatures present
|
||||
- Provenance timestamp must be recent (within 24h by default)
|
||||

|
||||
|
||||
## Section 10: Pagination
|
||||
|
||||
### T9: Cursor-Based Pagination
|
||||
|
||||
For large subgraphs, paginate nodes and edges:
|
||||
|
||||
**Request:**
|
||||
```http
|
||||
GET /v1/reachgraphs/blake3:a1b2c3d4...?cursor=eyJvZmZzZXQiOjUwfQ&limit=50
|
||||
```
|
||||
|
||||
**Response:**
|
||||
```json
|
||||
{
|
||||
"schemaVersion": "reachgraph.min@v1",
|
||||
"nodes": [ ... 50 nodes ... ],
|
||||
"edges": [ ... 75 edges ... ],
|
||||
"pagination": {
|
||||
"cursor": "eyJvZmZzZXQiOjEwMH0",
|
||||
"hasMore": true,
|
||||
"totalNodes": 250,
|
||||
"totalEdges": 380
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Cursor Format:** Base64-encoded JSON with offset and ordering info.

|
||||
|
||||
## Section 11: Rate Limiting & Tenant Isolation
|
||||
|
||||
### T10: Infrastructure
|
||||
|
||||
**Rate Limiting:**
|
||||
```csharp
|
||||
services.AddRateLimiter(options =>
|
||||
{
|
||||
options.AddPolicy("reachgraph-read", ctx =>
|
||||
RateLimitPartition.GetFixedWindowLimiter(
|
||||
ctx.User.FindFirst("tenant")?.Value ?? "anonymous",
|
||||
_ => new FixedWindowRateLimiterOptions
|
||||
{
|
||||
Window = TimeSpan.FromMinutes(1),
|
||||
PermitLimit = 100
|
||||
}));
|
||||
|
||||
options.AddPolicy("reachgraph-write", ctx =>
|
||||
RateLimitPartition.GetFixedWindowLimiter(
|
||||
ctx.User.FindFirst("tenant")?.Value ?? "anonymous",
|
||||
_ => new FixedWindowRateLimiterOptions
|
||||
{
|
||||
Window = TimeSpan.FromMinutes(1),
|
||||
PermitLimit = 20
|
||||
}));
|
||||
});
|
||||
```
|
||||
|
||||
**Tenant Isolation:**
|
||||
- `X-Tenant-ID` header required
|
||||
- RLS policies enforce at database level
|
||||
- Cache keys prefixed with tenant ID
|
||||
|
||||
---
|
||||
|
||||
## Section 12: Integration Tests
|
||||
|
||||
### T11: Test Suite
|
||||
|
||||
**File:** `src/ReachGraph/__Tests/StellaOps.ReachGraph.WebService.Tests/`
|
||||
|
||||
**Test Categories:**
|
||||
|
||||
1. **Endpoint Tests:**
|
||||
- `UpsertEndpointTests.cs` - Create, idempotency, validation
|
||||
- `RetrieveEndpointTests.cs` - Get, cache headers, compression
|
||||
- `SliceQueryTests.cs` - All slice query types
|
||||
- `ReplayEndpointTests.cs` - Determinism verification
|
||||
|
||||
2. **Integration Tests (Testcontainers):**
|
||||
- `PostgresIntegrationTests.cs` - Full CRUD with real database
|
||||
- `CacheIntegrationTests.cs` - Valkey cache behavior
|
||||
- `TenantIsolationTests.cs` - RLS enforcement
|
||||
|
||||
3. **Performance Tests:**
|
||||
- `LargeGraphTests.cs` - 1000+ nodes/edges
|
||||
- `ConcurrencyTests.cs` - Parallel requests
|
||||
|
||||
**Key Test Cases:**
|
||||
```csharp
|
||||
[Fact]
|
||||
public async Task Upsert_SameDigest_ReturnsOkNotCreated()
|
||||
{
|
||||
var graph = CreateSampleGraph();
|
||||
|
||||
var response1 = await _client.PostAsJsonAsync("/v1/reachgraphs", new { graph });
|
||||
var response2 = await _client.PostAsJsonAsync("/v1/reachgraphs", new { graph });
|
||||
|
||||
Assert.Equal(HttpStatusCode.Created, response1.StatusCode);
|
||||
Assert.Equal(HttpStatusCode.OK, response2.StatusCode);
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public async Task SliceByCve_ReturnsOnlyRelevantPaths()
|
||||
{
|
||||
var graph = await SetupGraphWithMultipleCves();
|
||||
var digest = await UpsertGraph(graph);
|
||||
|
||||
var response = await _client.GetAsync(
|
||||
$"/v1/reachgraphs/{digest}/slice?cve=CVE-2024-1234");
|
||||
|
||||
var slice = await response.Content.ReadFromJsonAsync<SliceResponse>();
|
||||
|
||||
Assert.All(slice.Sinks, sink =>
|
||||
Assert.Contains("CVE-2024-1234", sink.CveIds));
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public async Task Replay_SameInputs_ProducesSameDigest()
|
||||
{
|
||||
var inputs = await SetupDeterministicInputs();
|
||||
var graph = await ComputeGraph(inputs);
|
||||
var digest = await UpsertGraph(graph);
|
||||
|
||||
var response = await _client.PostAsJsonAsync("/v1/reachgraphs/replay", new
|
||||
{
|
||||
expectedDigest = digest,
|
||||
inputs = inputs
|
||||
});
|
||||
|
||||
var result = await response.Content.ReadFromJsonAsync<ReplayResponse>();
|
||||
|
||||
Assert.True(result.Match);
|
||||
Assert.Equal(digest, result.ComputedDigest);
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
1. **Cursor pagination**: Base64-encoded JSON for stateless pagination
|
||||
2. **Slice caching**: Hot slices cached in Valkey with 30min TTL
|
||||
3. **Replay logging**: All replay attempts logged for audit trail
|
||||
4. **Compression**: Gzip for responses > 10KB
|
||||
|
||||
### Risks
|
||||
1. **Slice query complexity**: Complex slices could be expensive
|
||||
- **Mitigation**: Depth limits, result size limits, query timeout
|
||||
2. **Cache invalidation**: Stale slices after graph update
|
||||
- **Mitigation**: Invalidate cache on upsert; content-addressed means updates create new digests
|
||||
3. **Replay performance**: Rebuilding large graphs is slow
|
||||
- **Mitigation**: Timeout with partial result; async replay for large graphs
|
||||
|
||||

# Sprint 1227.0012.0003 - Extractors, Policy Integration & UI
|
||||
|
||||
## Topic & Scope
|
||||
|
||||
Complete the **ReachGraph integration** across Scanner extractors, Policy engine, and Web Console UI. This sprint delivers the end-to-end "Why Reachable?" experience.
|
||||
|
||||
This sprint delivers:
|
||||
- Enhanced language extractors emitting `EdgeExplanation` with guards
|
||||
- Policy engine integration for subgraph-aware VEX decisions
|
||||
- Angular "Why Reachable?" panel component
|
||||
- CLI commands for slice queries and replay
|
||||
- End-to-end test coverage
|
||||
|
||||
**Working directories:**
|
||||
- `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.*/`
|
||||
- `src/Policy/StellaOps.Policy.Engine/`
|
||||
- `src/Web/StellaOps.Web/`
|
||||
- `src/Cli/StellaOps.Cli/`
|
||||
|
||||
**Cross-module touchpoints:**
|
||||
- `src/__Libraries/StellaOps.ReachGraph/` - Core library
|
||||
- `src/ReachGraph/` - Store APIs
|
||||
- `src/Signals/` - Runtime facts correlation
|
||||
|
||||
## Dependencies & Concurrency
|
||||
|
||||
- **Upstream**: Sprint 1227.0012.0001, Sprint 1227.0012.0002 - REQUIRED
|
||||
- **Downstream**: None (final sprint in series)
|
||||
- **Safe to parallelize with**: Extractor work (T1-T5) can run in parallel
|
||||
|
||||

## Section 1: Extractor Enhancement Overview
|
||||
|
||||
All language extractors should emit `EdgeExplanation` with:
|
||||
- `Type`: EdgeExplanationType enum value
|
||||
- `Loc`: Source location (file:line)
|
||||
- `Guard`: Predicate expression if guarded
|
||||
- `Confidence`: Score based on analysis type
|
||||

## Section 2: Node.js Import Walker
|
||||
|
||||
### T1: Feature Flag Detection
|
||||
|
||||
**File:** `src/Scanner/__Libraries/StellaOps.Scanner.Analyzers.Lang.Node/Internal/NodeImportWalker.cs`
|
||||
|
||||
**Enhancements:**
|
||||
|
||||
1. **Detect feature flag checks:**
|
||||
```javascript
|
||||
// Pattern: if (process.env.FEATURE_X) { require('lodash') }
|
||||
// Edge: { type: EnvGuard, guard: "FEATURE_X=truthy" }
|
||||
|
||||
// Pattern: if (config.enableNewFeature) { import('./new-module') }
|
||||
// Edge: { type: FeatureFlag, guard: "config.enableNewFeature=true" }
|
||||
```
|
||||
|
||||
2. **Detect dynamic requires:**
|
||||
```javascript
|
||||
// Pattern: require(someVar)
|
||||
// Edge: { type: DynamicLoad, confidence: 0.5 }
|
||||
|
||||
// Pattern: await import(`./modules/${name}`)
|
||||
// Edge: { type: DynamicLoad, confidence: 0.6 }
|
||||
```
|
||||
|
||||
3. **Detect platform checks:**
|
||||
```javascript
|
||||
// Pattern: if (process.platform === 'linux') { require('linux-only') }
|
||||
// Edge: { type: PlatformArch, guard: "platform=linux" }
|
||||
```
|
||||
|
||||
**Implementation:**
|
||||
```csharp
|
||||
private EdgeExplanation ClassifyImport(ImportNode node, ControlFlowContext ctx)
|
||||
{
|
||||
if (ctx.IsConditionalOnEnv(out var envVar))
|
||||
{
|
||||
return new EdgeExplanation
|
||||
{
|
||||
Type = EdgeExplanationType.EnvGuard,
|
||||
Loc = $"{node.File}:{node.Line}",
|
||||
Guard = $"{envVar}=truthy",
|
||||
Confidence = 0.9
|
||||
};
|
||||
}
|
||||
|
||||
if (ctx.IsConditionalOnPlatform(out var platform))
|
||||
{
|
||||
return new EdgeExplanation
|
||||
{
|
||||
Type = EdgeExplanationType.PlatformArch,
|
||||
Loc = $"{node.File}:{node.Line}",
|
||||
Guard = $"platform={platform}",
|
||||
Confidence = 0.95
|
||||
};
|
||||
}
|
||||
|
||||
if (node.IsDynamic)
|
||||
{
|
||||
return new EdgeExplanation
|
||||
{
|
||||
Type = EdgeExplanationType.DynamicLoad,
|
||||
Loc = $"{node.File}:{node.Line}",
|
||||
Confidence = 0.5
|
||||
};
|
||||
}
|
||||
|
||||
return new EdgeExplanation
|
||||
{
|
||||
Type = EdgeExplanationType.Import,
|
||||
Loc = $"{node.File}:{node.Line}",
|
||||
Confidence = 1.0
|
||||
};
|
||||
}
|
||||
```
|
||||

|
||||
|
||||
## Section 3: Python Extractor
|
||||
|
||||
### T2: Environment Guard Detection
|
||||
|
||||
**File:** `src/Scanner/__Libraries/StellaOps.Scanner.CallGraph/Extraction/Python/PythonCallGraphExtractor.cs`
|
||||
|
||||
**Patterns to detect:**
|
||||
```python
|
||||
# Pattern: if os.environ.get('FEATURE_X'):
|
||||
# Edge: { type: EnvGuard, guard: "FEATURE_X=truthy" }
|
||||
|
||||
# Pattern: if os.getenv('DEBUG', 'false') == 'true':
|
||||
# Edge: { type: EnvGuard, guard: "DEBUG=true" }
|
||||
|
||||
# Pattern: if sys.platform == 'linux':
|
||||
# Edge: { type: PlatformArch, guard: "platform=linux" }
|
||||
|
||||
# Pattern: import importlib; mod = importlib.import_module(name)
|
||||
# Edge: { type: DynamicLoad, confidence: 0.5 }
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Section 4: Java Extractor
|
||||
|
||||
### T3: System Property Detection
|
||||
|
||||
**File:** `src/Scanner/__Libraries/StellaOps.Scanner.CallGraph/Extraction/Java/JavaCallGraphExtractor.cs`
|
||||
|
||||
**Patterns to detect:**
|
||||
```java
|
||||
// Pattern: if (System.getenv("FEATURE_X") != null)
|
||||
// Edge: { type: EnvGuard, guard: "FEATURE_X=present" }
|
||||
|
||||
// Pattern: if ("true".equals(System.getProperty("feature.enabled")))
|
||||
// Edge: { type: FeatureFlag, guard: "feature.enabled=true" }
|
||||
|
||||
// Pattern: Class.forName(className)
|
||||
// Edge: { type: Reflection, confidence: 0.5 }
|
||||
|
||||
// Pattern: if (System.getProperty("os.name").startsWith("Linux"))
|
||||
// Edge: { type: PlatformArch, guard: "os=linux" }
|
||||
```

||||
**Patterns to detect:**
|
||||
```csharp
|
||||
// Pattern: if (Environment.GetEnvironmentVariable("FEATURE_X") is not null)
|
||||
// Edge: { type: EnvGuard, guard: "FEATURE_X=present" }
|
||||
|
||||
// Pattern: if (configuration["FeatureFlags:NewUI"] == "true")
|
||||
// Edge: { type: FeatureFlag, guard: "FeatureFlags:NewUI=true" }
|
||||
|
||||
// Pattern: Type.GetType(typeName)
|
||||
// Edge: { type: Reflection, confidence: 0.5 }
|
||||
|
||||
// Pattern: if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
|
||||
// Edge: { type: PlatformArch, guard: "os=linux" }

## Section 13: End-to-End Test
|
||||
|
||||
### T12: Full Pipeline Test
|
||||
|
||||
**File:** `src/__Tests/Integration/ReachGraphE2ETests.cs`
|
||||
|
||||
**Test Flow:**
|
||||
1. Scan a container image with known vulnerabilities
|
||||
2. Extract call graph with edge explanations
|
||||
3. Store reachability subgraph via API
|
||||
4. Query slice by CVE
|
||||
5. Verify slice contains expected paths
|
||||
6. Verify determinism via replay
|
||||
7. Export proof bundle
|
||||
8. Verify proof bundle offline
|
||||
|
||||
```csharp
|
||||
[Fact]
|
||||
public async Task FullPipeline_ScanToProofBundle_Succeeds()
|
||||
{
|
||||
// 1. Scan image
|
||||
var scanResult = await _scanner.ScanAsync("vulnerable-app:latest");
|
||||
|
||||
// 2. Extract call graph with explanations
|
||||
var callGraph = await _callGraphExtractor.ExtractAsync(scanResult);
|
||||
Assert.All(callGraph.Edges, e => Assert.NotEqual(EdgeExplanationType.Unknown, e.Why.Type));
|
||||
|
||||
// 3. Build and store reachability graph
|
||||
var reachGraph = await _reachGraphBuilder.BuildAsync(callGraph, scanResult.Sbom);
|
||||
var storeResult = await _reachGraphStore.UpsertAsync(reachGraph);
|
||||
Assert.True(storeResult.Created);
|
||||
|
||||
// 4. Query slice by CVE
|
||||
var cve = scanResult.Findings.First().CveId;
|
||||
var slice = await _reachGraphStore.GetSliceAsync(storeResult.Digest, $"?cve={cve}");
|
||||
Assert.NotEmpty(slice.Paths);
|
||||
|
||||
// 5. Verify paths contain entry and sink
|
||||
Assert.All(slice.Paths, path =>
|
||||
{
|
||||
Assert.True(path.Hops.First().IsEntrypoint);
|
||||
Assert.True(path.Hops.Last().IsSink);
|
||||
});
|
||||
|
||||
// 6. Verify determinism
|
||||
var replayResult = await _reachGraphStore.ReplayAsync(new
|
||||
{
|
||||
expectedDigest = storeResult.Digest,
|
||||
inputs = new
|
||||
{

|
||||
}
|
||||
});
|
||||
Assert.True(replayResult.Match);
|
||||
|
||||
// 7. Export proof bundle
|
||||

|
||||
## Decisions & Risks
|
||||
|
||||
### Decisions
|
||||
1. **Guard detection is best-effort**: Mark as Unknown if pattern not recognized
|
||||
2. **UI shows top 5 paths**: Pagination for more paths
|
||||
3. **CLI supports GraphViz output**: For external visualization tools
|
||||
4. **Proof bundle includes verification command**: Self-documenting
|
||||
|
||||
### Risks
|
||||
1. **Guard detection accuracy**: Some patterns may be missed
|
||||
- **Mitigation**: Conservative defaults; log unrecognized patterns for improvement
|
||||
2. **UI performance with large graphs**: Rendering many paths is slow
|
||||
- **Mitigation**: Virtual scrolling; limit displayed paths
|
||||
3. **Cross-language consistency**: Different extractors may classify differently
|
||||
- **Mitigation**: Shared classification rules; normalization layer
|
||||
|
||||
---
|
||||
|
||||
## Acceptance Criteria
|
||||
|
||||
**Sprint complete when:**
|
||||
- [x] All 5 language extractors emit EdgeExplanation with guard detection
|
||||
- [x] Policy gate consumes subgraph slices for decisions
|
||||
- [x] "Why Reachable?" panel displays paths with edge explanations
|
||||
- [x] "Copy proof bundle" exports verifiable DSSE envelope
|
||||
- [x] CLI `slice` command works for all query types
|
||||
- [x] CLI `replay` command verifies determinism
|
||||
- [x] E2E test passes: scan -> store -> query -> verify
|
||||
- [x] Guard detection coverage >= 80% for common patterns
|
||||
|
||||
---
|
||||
|
||||
## Success Metrics
|
||||
|
||||
1. **Triage latency**: "Why reachable?" query P95 < 200ms
|
||||
2. **Determinism rate**: 100% replay operations match
|
||||
3. **Coverage**: >80% edges have non-Unknown explanation type
|
||||

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Start with top 3 ecosystems (dotnet, java, node) | Covers majority of enterprise codebases |
|
||||
| Use static analysis for crypto detection | Runtime analysis would require instrumentation |
|
||||
| Flag weak crypto, don't auto-block | Organizations may have legacy constraints |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| False positives on crypto detection | Confidence scoring + manual override |
|
||||
| Performance impact of static analysis | Lazy extraction, cache results |
|
||||

---
|
||||
|
||||
## Objective
|
||||
|
||||
Complete CVSS v4.0 environmental metrics parsing in `CvssV4Engine.ParseEnvironmentalMetrics()`. Currently missing:
|
||||
- Modified Attack metrics (MAV, MAC, MAT, MPR, MUI)
|
||||
- Modified Impact metrics (MVC, MVI, MVA, MSC, MSI, MSA)
|
||||
|
||||
This enables organizations to compute environment-adjusted severity scores.
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
CVSS v4.0 separates metrics into:
|
||||
1. **Base** - Inherent vuln characteristics (fully implemented)
|
||||
2. **Threat** - Temporal factors (fully implemented)
|
||||
3. **Environmental** - Organization-specific context (partially implemented)
|
||||
|
||||
Environmental metrics allow organizations to adjust scores based on:
|
||||
- Security requirements (CR, IR, AR) - **Already implemented**
|
||||
- Modified base metrics - **Missing**

|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Parse but don't require environmental metrics | Most advisories only include base scores |
|
||||
| Use 'X' (Not Defined) as default | Per CVSS v4.0 specification |
|
||||
| Maintain separate env score in result | Some consumers only want base score |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| MacroVector lookup edge cases | Validate against FIRST calculator |
|
||||
| Performance regression | Profile score computation |
|
||||

## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| Consolidate existing types, not replace | Avoid breaking existing consumers |
|
||||
| JSON-LD optional (degrade to plain JSON) | Not all consumers need RDF semantics |
|
||||
| Reuse existing DSSE/Replay infrastructure | Avoid duplication, maintain consistency |
|
||||
| OCI attestation optional | Air-gap deployments may not have registry |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Schema migration for existing verdicts | Provide VerdictV1 → StellaVerdict adapter |
|
||||
| JSON-LD complexity | Keep @context minimal, test thoroughly |
|
||||
| OCI registry compatibility | Test with Docker Hub, Quay, Harbor, GHCR |

# Sprint 1227.0014.0002 — Verdict Evidence Graph & Policy Breadcrumb UI
|
||||
|
||||
## Metadata
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| Sprint ID | `1227.0014.0002` |
|
||||
| Module | `StellaOps.Web` (Angular) |
|
||||
| Type | `FE` (Frontend) |
|
||||
| Working Directory | `src/Web/StellaOps.Web/` |
|
||||
| Dependencies | Sprint 1227.0014.0001 (Backend) |
|
||||
| Estimated Tasks | 6 |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Add UI components to visualize verdict evidence and policy decisions, making the "why" of vulnerability verdicts accessible to users without requiring JSON inspection.
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### What Backend Provides
|
||||
|
||||
The backend (Sprint 1227.0014.0001) provides:
|
||||
- `VerdictEvidenceGraph` with typed nodes and edges
|
||||
- `PolicyPath` array with rule → decision → reason
|
||||
- `VerdictInputs` with feed sources and hashes
|
||||
- Signed JSON-LD artifact download
|
||||
|
||||
### What's Missing in UI
|
||||
|
||||
1. **Evidence Mini-Graph** - Visual graph of 5-12 nodes showing evidence flow
|
||||
2. **Policy Breadcrumb** - "Vendor VEX → Require Reachability → Decision" trail
|
||||
3. **Verdict Download Actions** - One-click export buttons
|
||||
|
||||

|
||||
|
||||

|
||||
|
||||
## Design Guidelines
|
||||
|
||||
### Color Palette
|
||||
- **CVE nodes**: `--color-danger-500` (red)
|
||||
- **VEX nodes**: `--color-success-500` (green) for not_affected, yellow for affected
|
||||
- **CallGraph nodes**: `--color-info-500` (blue)
|
||||
- **Config nodes**: `--color-neutral-500` (gray)
|
||||
- **Edges**: `--color-neutral-400` with labels in `--color-neutral-600`
|
||||
|
||||
### Accessibility
|
||||
- All interactive elements keyboard accessible
|
||||
- ARIA labels for graph nodes and edges
|
||||
- High contrast mode support
|
||||
- Screen reader announces decision path
|
||||
|
||||
### Performance
|
||||
- Lazy load D3.js/ngx-graph bundle
|
||||
- Virtual scrolling for large policy paths
|
||||
- Debounce hover tooltips
|
||||

|
||||
|
||||
## Decisions & Risks
|
||||
|
||||
| Decision | Rationale |
|
||||
|----------|-----------|
|
||||
| D3.js over vis.js | Better Angular integration, smaller bundle |
|
||||
| Standalone components | Tree-shakeable, faster loading |
|
||||
| Embedded in finding detail | Most common access pattern |
|
||||
|
||||
| Risk | Mitigation |
|
||||
|------|------------|
|
||||
| Graph performance with large nodes | Limit to 12 nodes, paginate rest |
|
||||
| D3 bundle size | Dynamic import, code split |
|
||||
