Set Justification with Status + +When testing `not_affected` status, pass justification to `WithFinalStatus`: + +```csharp +.WithFinalStatus(VexStatus.NotAffected, VexJustification.VulnerableCodeNotPresent) +``` + +### 4. Use Correct Types + +The `AddStatement` method requires proper types: +- `VexProofIssuer` - Not a string +- `VexProofWeight` with `VexProofWeightFactors` - Not a decimal + +```csharp +builder.AddStatement( + id: "stmt-001", + source: "vendor-csaf", + issuer: new VexProofIssuer("Vendor", IssuerCategory.Vendor, TrustTier.Authoritative), + status: VexStatus.Fixed, + justification: null, + weight: new VexProofWeight(0.95m, new VexProofWeightFactors(0.95m, 1.0m, 0.9m, 1.0m, 0.8m)), + timestamp: _fixedTime, + signatureVerified: true); +``` + +### 5.
