# 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.

|
||||
|
||||
## Recommended Implementation Batches
|
||||
|
||||
### Batch 001: Core Wiring (P0 - Do First)
|
||||
Wire existing components to produce VEX claims from binary matches.
|
||||
|
||||
| Sprint | Topic | Effort |
|
||||
|--------|-------|--------|
|
||||
| SPRINT_1227_0001_0001 | Binary→VEX claim generator | Medium |
|
||||
| SPRINT_1227_0001_0002 | Resolution API + cache | Medium |
|
||||
|
||||
**Outcome:** Auto-flip CVEs to "Not Affected (patched)" when fingerprint matches fixed binary.
|
||||
|
||||
### Batch 002: Corpus Seeding (P1 - High Value)
|
||||
Enable function-level CVE attribution via reproducible builds.
|
||||
|
||||
| Sprint | Topic | Effort |
|
||||
|--------|-------|--------|
|
||||
| SPRINT_1227_0002_0001 | Reproducible builders + function fingerprints | High |
|
||||
|
||||
**Outcome:** "This function was patched in DSA-5343-1" with proof.
|
||||
|
||||
### Batch 003: User Experience (P2 - Enhancement)
|
||||
Surface resolution evidence in UI.
|
||||
|
||||
| Sprint | Topic | Effort |
|
||||
|--------|-------|--------|
|
||||
| SPRINT_1227_0003_0001 | Backport resolution UI panel | Medium |
|
||||
|
||||
**Outcome:** Users see "Fixed (backport: DSA-5343-1)" with drill-down.

|
||||
|
||||
## 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

|-------|-------|
|

| **Sprint ID** | SPRINT_1227_0001_0001 |
|
||||
| **Batch** | 001 - Core Wiring |
|
||||
| **Module** | LB (Library) |
|
||||
| **Topic** | Binary-to-VEX claim auto-generation |
|

| **Priority** | P0 - Critical Path |
|
||||
| **Estimated Effort** | Medium |
|
||||
| **Dependencies** | BinaryIndex.FixIndex, Excititor.Core |

|
||||
|
||||
## 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`
|
||||
|
||||
Test cases:
|
||||
- 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
|
||||
- DSSE envelope structure validation
|
||||

3. [ ] Observation ID is deterministic for same inputs
|
||||
4. [ ] DSSE envelope generated when `SignWithDsse = true`
|
||||
5. [ ] Batch processing handles 1000+ matches efficiently
|
||||
6. [ ] All status mappings produce correct VEX semantics
|
||||
7. [ ] Unit test coverage > 90%

|
||||
|
||||
## 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 |

| **Batch** | 001 - Core Wiring |
|
||||
| **Module** | BE (Backend) |
|

| **Topic** | Resolution API endpoint + Valkey cache |
|

|
||||
|
||||
## 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
|
||||
|
||||

|
||||
|
||||

|
||||
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 |

|
||||
|
||||
---
|
||||
|
||||
## 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)

**Normalization Requirements:**
|
||||
- Strip `__DATE__`, `__TIME__` macros
|
||||
- Normalize build paths (`/build/` prefix)
|
||||
- Reproducible ar/tar ordering
|
||||
- Fixed locale (`C.UTF-8`)
|
||||
- Pinned toolchain versions per distro release

|
||||
|
||||
## 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 |
|
||||

# Sprint: Backport-Aware Resolution UI Integration
|
||||
|
||||
| Field | Value |
|
||||
|-------|-------|
|
||||
| **Sprint ID** | SPRINT_1227_0003_0001 |
|
||||
| **Batch** | 003 - User Experience |
|
||||
| **Module** | FE (Frontend) |
|
||||
| **Topic** | Backport resolution UI panel + proof visualization |
|
||||
| **Priority** | P2 - Enhancement |
|
||||
| **Estimated Effort** | Medium |
|
||||
| **Dependencies** | SPRINT_1227_0001_0001, SPRINT_1227_0001_0002 |
|
||||
| **Working Directory** | `src/Web/StellaOps.Web/` |
|
||||
|
||||
---
|
||||
|
||||
## Objective
|
||||
|
||||
Surface binary fingerprint resolution results in the vulnerability details UI with:
|
||||
1. "Backport-aware resolution" status chip
|
||||
2. Evidence drill-down (advisory ID, patch hash, matched fingerprints)
|
||||
3. Function-level diff visualization
|
||||
4. Proof attestation viewer
|
||||
|
||||
---
|
||||
|
||||
## Background
|
||||
|
||||
### Current State
|
||||
- Vulnerability details panel shows package, CVE, severity
|
||||
- VEX status displayed as simple badge
|
||||
- No visibility into resolution method or evidence
|
||||
- No function-level proof visualization
|
||||
|
||||
### Target State
|
||||
- Resolution source indicator (version match vs. binary fingerprint)
|
||||
- "Show why" toggle revealing evidence tree
|
||||
- Function diff viewer for changed methods
|
||||
- DSSE attestation verification link
|
||||
- Clear distinction: "Fixed (backport detected)" vs. "Fixed (version match)"
|
||||
|
||||
---
|
||||
|
||||
## Deliverables
|
||||
|
||||
### D1: Resolution Status Chip Component
|
||||
**File:** `src/Web/StellaOps.Web/src/app/shared/components/resolution-chip/resolution-chip.component.ts`
|
||||
|
||||
```typescript
|
||||
@Component({
|
||||
selector: 'so-resolution-chip',
|
||||
templateUrl: './resolution-chip.component.html',
|
||||
styleUrls: ['./resolution-chip.component.scss']
|
||||
})
|
||||
export class ResolutionChipComponent {
|
||||
@Input() resolution: VulnResolutionSummary;
|
||||
|
||||
get chipColor(): string {
|
||||
switch (this.resolution.status) {
|
||||
case 'Fixed': return 'success';
|
||||
case 'Vulnerable': return 'danger';
|
||||
case 'NotAffected': return 'info';
|
||||
default: return 'warning';
|
||||
}
|
||||
}
|
||||
|
||||
get chipLabel(): string {
|
||||
if (this.resolution.matchType === 'fingerprint') {
|
||||
return `Fixed (backport: ${this.resolution.distroAdvisoryId})`;
|
||||
}
|
||||
return this.resolution.status;
|
||||
}
|
||||
|
||||
get hasEvidence(): boolean {
|
||||
return !!this.resolution.evidence;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Template:**
|
||||
```html
|
||||
<mat-chip [ngClass]="chipColor" [matTooltip]="tooltipText">
|
||||
<mat-icon *ngIf="resolution.matchType === 'fingerprint'">fingerprint</mat-icon>
|
||||
<mat-icon *ngIf="resolution.matchType === 'build_id'">verified</mat-icon>
|
||||
{{ chipLabel }}
|
||||
<button mat-icon-button *ngIf="hasEvidence" (click)="showEvidence()">
|
||||
<mat-icon>info_outline</mat-icon>
|
||||
</button>
|
||||
</mat-chip>
|
||||
```
|
||||
|
||||
### D2: Evidence Drawer Component
|
||||
**File:** `src/Web/StellaOps.Web/src/app/findings/components/evidence-drawer/evidence-drawer.component.ts`
|
||||
|
||||
Slide-out panel showing:
|
||||
1. Match method (Build-ID / Fingerprint / Hash)
|
||||
2. Confidence score with visual gauge
|
||||
3. Distro advisory reference (link to DSA/RHSA)
|
||||
4. Patch commit (link to upstream)
|
||||
5. Matched function list
|
||||
6. DSSE attestation (copyable)
|
||||
|
||||
### D3: Function Diff Viewer
|
||||
**File:** `src/Web/StellaOps.Web/src/app/findings/components/function-diff/function-diff.component.ts`
|
||||
|
||||
For function-level evidence:
|
||||
- Side-by-side comparison: vulnerable ↔ patched
|
||||
- Syntax highlighting for disassembly (x86-64, ARM64)
|
||||
- Changed lines highlighted
|
||||

|
||||
- Show payload type, signer key ID
|
||||
- Verify signature status (call backend `/verify`)
|
||||
- Link to Rekor transparency log (if indexed)
|
||||
- Copy-to-clipboard for full envelope
|
||||
|
||||
### D5: API Integration Service

@Injectable({ providedIn: 'root' })
|
||||
export class ResolutionService {
|
||||
constructor(private http: HttpClient) {}
|
||||
|
||||
resolveVulnerability(request: VulnResolutionRequest): Observable<VulnResolutionResponse> {
|
||||
return this.http.post<VulnResolutionResponse>('/api/v1/resolve/vuln', request);
|
||||
}
|
||||
|

verifyAttestation(dsseEnvelope: string): Observable<AttestationVerifyResult> {
|
||||
return this.http.post<AttestationVerifyResult>('/api/v1/attestations/verify', {
|
||||
envelope: dsseEnvelope
|
||||
});
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### D6: Finding Detail Page Integration

## 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 |
|
||||
