# Proof-Driven Moats: Architecture Specification
|
||||
|
||||
**Version:** 1.0.0
|
||||
**Status:** Design
|
||||
**Owner:** Platform Architecture
|
||||
**Last Updated:** 2025-12-23
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document specifies the architecture for **Proof-Driven Moats**, a dual capability that establishes StellaOps as best-in-class for vulnerability assessment accuracy:
|
||||
|
||||
1. **Patch-Aware Backport Detector**: Automated detection of distro backports with cryptographic proof, eliminating false positives from version-string mismatches.
|
||||
|
||||
2. **Regional Crypto & Offline Audit Packs**: Jurisdiction-compliant attestation bundles with multi-profile signing (eIDAS, FIPS, GOST, SM, PQC).
|
||||
|
||||
---
|
||||
|
||||
## 1. Strategic Goals
|
||||
|
||||
### 1.1 Business Objectives
|
||||
|
||||
- **Eliminate backport false positives** without human intervention
|
||||
- **Provide cryptographic proof** for every vulnerability verdict
|
||||
- **Enable global deployment** with regional crypto compliance
|
||||
- **Support air-gapped environments** with sealed audit packs
|
||||
- **Establish competitive moat** through binary-level analysis
|
||||
|
||||
### 1.2 Technical Objectives
|
||||
|
||||
- **Deterministic, reproducible proofs** with canonical hashing
|
||||
- **Pluggable crypto profiles** for jurisdiction compliance
|
||||
- **Four-tier backport detection**: distro feeds → changelog → patches → binary
|
||||
- **Offline-first design** with embedded trust anchors
|
||||
- **PostgreSQL-backed storage** with efficient querying

## 3. Backport Detector Architecture
|
||||
|
||||
### 3.1 Four-Tier Detection System
|
||||
|
||||

|
||||

|
||||
|
||||
Tier 2: Source Changelog Parsing (NEW)
|
||||
├─ debian/changelog CVE mentions
|
||||
├─ RPM %changelog CVE mentions
|
||||

||||
Confidence: 0.85-0.95
|
||||
```
|
||||
|
||||
### 3.2 Decision Algorithm
|
||||
|
||||
```python
|
||||
def decide_cve_status(cve_id, package, installed_version, evidences):
|
||||
"""Deterministic, ordered decision algorithm with proof generation."""
|
||||
|

|

# Step 1: Check Tier 1 (distro feeds)
|
||||
for feed_evidence in evidences.filter(tier=1).sort_by_confidence():

||||

|
||||

||||
if cve_id in changelog_evidence.cve_mentions:
|
||||
if version_compare(installed_version, changelog_evidence.version) >= 0:
|
||||
proof.add(changelog_evidence)
|
||||
return VerdictWithProof("FIXED", proof, confidence=changelog_evidence.confidence)
|
||||
|
||||
# Step 3: Check Tier 3 (patches)
|
||||
for patch_evidence in evidences.filter(tier=3).sort_by_confidence():
|
||||
if cve_id in patch_evidence.cve_references:
|
||||
proof.add(patch_evidence)
|
||||
return VerdictWithProof("FIXED", proof, confidence=patch_evidence.confidence)
|
||||
|
||||
# Step 4: Check Tier 4 (binary fingerprints)
|
||||
for binary_evidence in evidences.filter(tier=4):
|
||||
if binary_evidence.fingerprint_match and not binary_evidence.vulnerable_match:
|
||||
proof.add(binary_evidence)
|
||||
return VerdictWithProof("FIXED", proof, confidence=binary_evidence.confidence)
|
||||
|
||||
# Default: vulnerable
|
||||
proof.add_note("No fix evidence found across all tiers")
|
||||
return VerdictWithProof("VULNERABLE", proof, confidence=0.95)
|
||||
```

## 4. Regional Crypto Architecture
|
||||
|
||||
### 4.1 Pluggable Crypto Abstraction
|
||||
|
||||
```csharp
|
||||
// Core abstraction (StellaOps.Cryptography)
|
||||
public interface IContentSigner
|
||||
{
|
||||
string KeyId { get; }
|
||||
SignatureProfile Profile { get; }
|
||||
Task<SignatureResult> SignAsync(ReadOnlyMemory<byte> payload, CancellationToken ct);
|
||||
}
|
||||
|
||||
public interface IContentVerifier
|
||||
{
|
||||
Task<VerificationResult> VerifyAsync(
|
||||
ReadOnlyMemory<byte> payload,
|
||||
Signature signature,
|
||||
CancellationToken ct);
|
||||
}
|
||||
|
||||
public enum SignatureProfile
|
||||
{
|
||||
EdDsa, // Baseline (Ed25519)
|
||||
EcdsaP256, // FIPS 186-4
|
||||
RsaPss, // FIPS 186-4
|
||||
Gost2012, // GOST R 34.10-2012
|
||||
SM2, // GM/T 0003.2-2012
|
||||
Eidas, // ETSI TS 119 312
|
||||
Dilithium, // NIST PQC (optional)
|
||||
Falcon // NIST PQC (optional)
|
||||
}
|
||||
|
||||
// Multi-profile signing
|
||||
public class MultiProfileSigner : IContentSigner
|
||||
{
|
||||
private readonly IReadOnlyList<IContentSigner> _signers;
|
||||
|
||||
public async Task<MultiSignatureResult> SignAllAsync(
|
||||
ReadOnlyMemory<byte> payload,
|
||||
CancellationToken ct)
|
||||
{
|
||||
var signatures = new List<Signature>();
|
||||
foreach (var signer in _signers)
|
||||
{
|
||||
var result = await signer.SignAsync(payload, ct);
|
||||
signatures.Add(result.Signature);
|
||||
}
|
||||
return new MultiSignatureResult(signatures);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4.2 Profile Implementations
|
||||
|
||||
Each profile is a separate NuGet package:
|
||||
|
||||
- `StellaOps.Cryptography.Profiles.EdDsa` - Baseline (libsodium)
|
||||
- `StellaOps.Cryptography.Profiles.Ecdsa` - FIPS (System.Security.Cryptography)
|
||||
- `StellaOps.Cryptography.Profiles.Rsa` - FIPS (System.Security.Cryptography)
|
||||
- `StellaOps.Cryptography.Profiles.Gost` - Russia (BouncyCastle or CryptoPro)
|
||||
- `StellaOps.Cryptography.Profiles.SM` - China (BouncyCastle)
|
||||
- `StellaOps.Cryptography.Profiles.Eidas` - EU (DSS library)
|
||||
- `StellaOps.Cryptography.Profiles.Pqc` - Post-quantum (liboqs)
|
||||
|
||||
### 4.3 Configuration-Driven Selection

|

## 5. ProofBlob Specification
|
||||
|
||||
### 5.1 Data Model
|
||||
|
||||
```csharp
|
||||
// StellaOps.Attestor.ProofChain
|

public sealed record ProofBlob
|

public required string SubjectId { get; init; } // CVE-XXXX-YYYY + PURL
|
||||
public required ProofBlobType Type { get; init; }
|

||||
BinaryFingerprint, // Tier 4
|
||||
VersionComparison, // Supporting evidence
|
||||
BuildCatalog // Build ID mapping
|
||||
}
|
||||
```
|
||||
|
||||
### 5.2 Canonical Hashing
|
||||
|
||||
```csharp
|
||||
public static class ProofHashing
|

{
|
||||
public static string ComputeProofHash(ProofBlob blob)
|
||||
{

||||
// Clone without ProofHash field
|

var normalized = blob with { ProofHash = null };
|
||||
|
||||
// Canonicalize (sorted keys, stable ordering)
|
||||
var canonical = CanonJson.Canonicalize(normalized);
|
||||
|
||||
// SHA-256
|
||||
var hash = SHA256.HashData(canonical);
|
||||
return "sha256:" + Convert.ToHexString(hash).ToLowerInvariant();
|
||||
}
|
||||
|
||||
public static ProofBlob WithHash(ProofBlob blob)
|
||||
{
|
||||
var hash = ComputeProofHash(blob);
|
||||
return blob with { ProofHash = hash };
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 5.3 Storage Schema
|
||||
|
||||
```sql
