# Sprint SPRINT_20260107_005_001_LB - CycloneDX 1.7 Evidence Models
> **Parent:** [SPRINT_20260107_005_000_INDEX](./SPRINT_20260107_005_000_INDEX_cyclonedx17_native_fields.md)
> **Status:** DONE
> **Last Updated:** 2026-01-08
## Objective
Implement native CycloneDX 1.7 evidence field population in the Scanner SBOM generation pipeline, replacing custom `stellaops:evidence[n]` properties with spec-compliant `component.evidence.*` structures.
## Working Directory
- `src/Scanner/__Libraries/StellaOps.Scanner.Emit/`
- `src/Scanner/__Tests/StellaOps.Scanner.Emit.Tests/`
## Prerequisites
- None (foundation sprint)
## Dependencies
| Dependency | Package | Usage |
|------------|---------|-------|
| CycloneDX | `CycloneDX.Models` | Evidence model classes |
| Scanner Core | `StellaOps.Scanner.Core` | Component evidence data |
---
## Current Implementation
Evidence is stored as custom properties in `CycloneDxComposer.cs`:
```csharp
// CURRENT: Custom property storage (lines 400-414)
for (var index = 0; index < component.Evidence.Length; index++)
{
var evidence = component.Evidence[index];
properties.Add(new Property
{
Name = $"stellaops:evidence[{index}]",
Value = $"{evidence.Kind}:{evidence.Value}@{evidence.Source}",
});
}
```
## Target Implementation
Use native CycloneDX 1.7 evidence fields:
```csharp
// TARGET: Native evidence field population
var cdxComponent = new Component
{
Evidence = new Evidence
{
Identity = BuildIdentityEvidence(component),
Occurrences = BuildOccurrences(component),
Licenses = BuildLicenseEvidence(component),
Copyright = BuildCopyrightEvidence(component),
}
};
```

# Sprint SPRINT_20260107_006_003_BE - AdvisoryAI Chat Interface
> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
> **Status:** TODO
> **Last Updated:** 2026-01-07
## Objective
Implement a conversational chat interface for AdvisoryAI, enabling multi-turn dialogue while maintaining grounded responses with object links. The model can propose actions, but execution is gated by policy-aware automation.
## Working Directory
- `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/`
- `src/AdvisoryAI/StellaOps.AdvisoryAI.WebService/Endpoints/`
- `src/Web/StellaOps.Web/src/app/features/advisory-ai/`
## Prerequisites
- Existing: AdvisoryAI grounded responses
- Existing: Guardrail pipeline
---
## Advisory Vision
> "**Grounded answers only**: model responses must cite **internal object links** (SBOM IDs, DSSE URIs, call-graph nodes).
> **Guardrails**: model can propose actions, but execution is gated by **Policy-aware Automation**."
## Example User Flows
**Flow 1: Integration Question**
```
User: "How do I integrate GitLab?"
AdvisoryAI:
Here's how to integrate GitLab with StellaOps:
**Steps:**
1. Create GitLab application (Admin → Applications)
2. Configure OIDC claims: `groups`, `email`
3. Add webhook secret to StellaOps Authority
**One-click setup:**
[Generate Integration Manifest] ← Button
**References:**
- Authority keys: [auth:keys/gitlab-oidc ↗]
- Webhook URL: `https://stellaops.example.com/webhooks/gitlab`
- Required scopes: [docs:scopes/ci-webhook ↗]
```
**Flow 2: Exploitability Question**
```
User: "Is CVE-2023-44487 exploitable here?"
AdvisoryAI:
**Verdict:** ⚠️ AFFECTED (reachable)
**Evidence:**
- Reachability: [reach:api-gateway:grpc.Server ↗] → 95% confident
- Runtime: 1,247 hits in last 24h [runtime:api-gateway:traces ↗]
- EPSS: 0.97 (top 1% exploitability)
**Recommendation:** Upgrade to patched version or apply WAF rule.
**Actions:**
[Approve] [Quarantine] [Defer with VEX]
```

**Blocker:** This task requires modifying `FindingWorkflowService` in the Findings module to add hook points after `AcceptRiskAsync`, `TargetFixAsync`, and other decision methods. The working directory for this sprint is `src/OpsMemory/`, modifying Findings would require cross-module coordination. Recommend:
1. Create a separate sprint task in Findings module to add `IDecisionHook` interface
2. Register OpsMemoryHook implementation via DI
3. Fire-and-forget call from `FindingWorkflowService` to all registered hooks

# Sprint SPRINT_20260107_006_005_BE - Reproduce Button Implementation
> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
> **Status:** TODO
> **Last Updated:** 2026-01-07
## Objective
Complete the Reproduce button implementation, enabling auditors to trigger deterministic replay using the same feed hashes, rules, and seeds to recreate any verdict. This is the key differentiator: "auditors rerun your exact decision graph; rivals hand over PDFs."
## Working Directory
- `src/Timeline/StellaOps.Timeline.WebService/Endpoints/`
- `src/Replay/StellaOps.Replay.Core/`
- `src/Web/StellaOps.Web/src/app/shared/components/reproduce/`
## Prerequisites
- Existing: `ITimelineReplayOrchestrator` interface (defined)
- Existing: `ReplayEndpoints.cs` (stubbed)
- Existing: Timeline module with HLC ordering
---
## Advisory Vision
> "**Reproduce** button: spins deterministic replay using the same feed hashes, rules, and seeds to recreate the verdict."
## Current State
The replay interface is defined but endpoints are stubbed:
- `ITimelineReplayOrchestrator` - interface exists
- `ReplayOperation` model - defined
- `ReplayEndpoints` - has TODO markers
## Target State
Fully functional Reproduce button:
1. User clicks "Reproduce" on any verdict
2. System queues replay job with input manifests
3. Replay engine recreates verdict with same inputs
4. UI shows progress and comparison result
5. Determinism verification: original digest vs replay digest

## Design Notes
### Visual Design
The playbook suggestion component should:

# Sprint 20260107_007_SIGNER_test_stabilization · Signer Test Stabilization
## Topic & Scope
- Stabilize Signer module tests by fixing failing KeyManagement, Fulcio, and negative-request cases.
- Preserve deterministic validation behavior for PoE, DSSE payloads, and certificate time parsing.
- Owning directory: `src/Signer`; evidence: passing `StellaOps.Signer.Tests` and updated test fixtures.
- **Working directory:** `src/Signer`.
## Dependencies & Concurrency
- No upstream sprints required.
- Parallel work in other modules is safe; no shared contracts modified.
## Documentation Prerequisites
- `docs/modules/signer/architecture.md`
- `docs/modules/signer/guides/keyless-signing.md`
- `docs/modules/platform/architecture-overview.md`
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |

| 3 | SIGNER-TEST-003 | DONE | SIGNER-TEST-001 | Signer Guild | Update Signer negative request tests to include PoE where required and keep deep predicate handling deterministic. |
| 4 | SIGNER-TEST-004 | DONE | SIGNER-TEST-002, SIGNER-TEST-003 | Signer Guild | Run Signer tests and record remaining failures. |

| 2026-01-08 | Sprint created; tests failing in Signer module. | Planning |
| 2026-01-08 | Completed SIGNER-TEST-001/002/003; started SIGNER-TEST-004. | Codex |
| 2026-01-08 | Completed SIGNER-TEST-004; Signer tests pass after key rotation and chain validation fixes. | Codex |
## Decisions & Risks
- Validate PoE before payload validation; negative tests must include PoE to reach deeper validation paths.
## Next Checkpoints
- 2026-01-09 · Signer test stabilization check-in (Signer Guild).

---
## Lattice Transition Rules
Implement the following state transition matrix in `ReachabilityLattice`:
| Current State | Evidence | New State | Confidence Delta |
|---------------|----------|-----------|------------------|
| Unknown | Static path found | StaticReachable | +0.30 |
| Unknown | Static no path | StaticUnreachable | +0.40 |
| StaticReachable | Runtime observed | RuntimeObserved | +0.30 |
| StaticReachable | Runtime window expired, no observation | RuntimeUnobserved | +0.20 |
| StaticUnreachable | Runtime observed (unexpected) | Contested | -0.20 |
| RuntimeObserved | Second source confirms | ConfirmedReachable | +0.20 |
| RuntimeUnobserved | Second source confirms | ConfirmedUnreachable | +0.20 |
| Any | Conflicting evidence | Contested | set to 0.20 |
---
## Confidence Calculation
```csharp
public sealed class ConfidenceCalculator
{
private static readonly ImmutableDictionary<LatticeState, double> BaseConfidence =
new Dictionary<LatticeState, double>
{
[LatticeState.Unknown] = 0.00,
[LatticeState.StaticReachable] = 0.30,
[LatticeState.StaticUnreachable] = 0.40,
[LatticeState.RuntimeObserved] = 0.70,
[LatticeState.RuntimeUnobserved] = 0.60,
[LatticeState.ConfirmedReachable] = 0.90,
[LatticeState.ConfirmedUnreachable] = 0.95,
[LatticeState.Contested] = 0.20
}.ToImmutableDictionary();
public double Calculate(
LatticeState state,
StaticEvidence? staticEvidence,
RuntimeEvidence? runtimeEvidence)
{
var baseScore = BaseConfidence[state];
// Apply modifiers based on evidence quality
if (staticEvidence is not null)
{
// Shorter paths = higher confidence
baseScore += Math.Min(0.1, 0.02 * (10 - staticEvidence.ShortestPathLength));
// No guards = higher confidence
if (staticEvidence.Guards.IsEmpty)
baseScore += 0.05;
}
if (runtimeEvidence is not null)
{
// More observations = higher confidence
baseScore += Math.Min(0.1, Math.Log10(runtimeEvidence.HitCount + 1) * 0.02);
// Longer observation window = higher confidence
baseScore += Math.Min(0.05, runtimeEvidence.ObservationWindowDays * 0.005);
}
return Math.Clamp(baseScore, 0.0, 1.0);
}
}
```
---
## Evidence URI Scheme
Implement `stella://` URI construction:
```csharp
public sealed class EvidenceUriBuilder
{
public string BuildReachGraphUri(string digest)
=> $"stella://reachgraph/{digest}";
public string BuildReachGraphSliceUri(string digest, string symbolId)
=> $"stella://reachgraph/{digest}/slice?symbol={Uri.EscapeDataString(symbolId)}";
public string BuildRuntimeFactsUri(string tenantId, string artifactDigest)
=> $"stella://signals/runtime/{tenantId}/{artifactDigest}";
public string BuildRuntimeFactsUri(string tenantId, string artifactDigest, string symbolId)
=> $"stella://signals/runtime/{tenantId}/{artifactDigest}?symbol={Uri.EscapeDataString(symbolId)}";
public string BuildCveMappingUri(string cveId)
=> $"stella://cvemap/{Uri.EscapeDataString(cveId)}";
public string BuildAttestationUri(string digest)
=> $"stella://attestation/{digest}";
}
```
---
## Integration Requirements
### ReachGraph Adapter
Query `IReachGraphSliceService` for:
- Symbol presence in graph
- Path count from entrypoints
- Shortest path length
- Guard conditions on edges
### Signals Adapter
Query `IRuntimeFactsService` for:
- Symbol observation records
- Hit counts
- First/last seen timestamps
- Context information (container, route)
---
## Determinism Requirements
1. **Canonical content digest:** SHA-256 of canonical JSON (RFC 8785)
2. **Stable ordering:** Sort evidence URIs lexicographically
3. **Time injection:** Use `TimeProvider` for `ComputedAt`
4. **Culture invariance:** `InvariantCulture` for all string operations
---
## Testing Requirements
### Unit Tests
| Test Class | Coverage |
|------------|----------|
| `ReachabilityLatticeTests` | All state transitions |
| `ConfidenceCalculatorTests` | All confidence scenarios |
| `EvidenceUriBuildTests` | URI construction, escaping |
| `HybridReachabilityResultTests` | Serialization, determinism |
### Integration Tests
| Test Class | Coverage |
|------------|----------|
| `ReachGraphAdapterTests` | ReachGraph mock integration |
| `SignalsAdapterTests` | Signals mock integration |
| `ReachabilityIndexTests` | End-to-end query flow |
### Property Tests
| Property | Description |
|----------|-------------|
| Lattice monotonicity | State transitions never decrease evidence strength (except Contested) |
| Confidence bounds | Always 0.0-1.0 |
| Determinism | Same inputs = same ContentDigest |

## Normalization Rules
### General Rules
1. **Lowercase everything** (case-insensitive matching)
2. **Strip whitespace** (leading/trailing, collapse internal)
3. **Normalize separators:** `/` and `::` become `.`
4. **Simplify signatures:** Full type names to simple names
### .NET Normalization
```csharp
// Input: "System.Void StellaOps.Scanner.Core.SbomGenerator::GenerateAsync(System.Threading.CancellationToken)"
// Output:
// Namespace: "stellaops.scanner.core"
// Type: "sbomgenerator"
// Method: "generateasync"
// Signature: "(cancellationtoken)"
public class DotNetSymbolNormalizer : ISymbolNormalizer
{
public CanonicalSymbol Normalize(RawSymbol raw)
{
// Parse: [ReturnType] Namespace.Type::Method(Params)
var match = Regex.Match(raw.Value,
@"^(?:[\w.]+\s+)?(?<ns>[\w.]+)\.(?<type>\w+)::(?<method>\w+)\((?<params>[^)]*)\)$");
if (!match.Success)
throw new SymbolParseException($"Cannot parse .NET symbol: {raw.Value}");
var ns = match.Groups["ns"].Value.ToLowerInvariant();
var type = match.Groups["type"].Value.ToLowerInvariant();
var method = match.Groups["method"].Value.ToLowerInvariant();
var signature = SimplifySignature(match.Groups["params"].Value);
return BuildCanonical(ns, type, method, signature, raw);
}
private static string SimplifySignature(string fullParams)
{
// "System.Threading.CancellationToken, System.String" -> "(cancellationtoken, string)"
var parts = fullParams.Split(',')
.Select(p => p.Trim().Split('.').Last().ToLowerInvariant())
.Where(p => !string.IsNullOrEmpty(p));
return $"({string.Join(", ", parts)})";
}
}
```
### Java Normalization
```csharp
// Input: "org/apache/log4j/core/lookup/JndiLookup.lookup(Ljava/lang/String;)Ljava/lang/String;"
// Output:
// Namespace: "org.apache.log4j.core.lookup"
// Type: "jndilookup"
// Method: "lookup"
// Signature: "(string)"
public class JavaSymbolNormalizer : ISymbolNormalizer
{
public CanonicalSymbol Normalize(RawSymbol raw)
{
// Parse: package/Class.method(descriptor)returnType
var match = Regex.Match(raw.Value,
@"^(?<pkg>[\w/]+)/(?<class>\w+)\.(?<method>\w+)\((?<desc>[^)]*)\)");
if (!match.Success)
throw new SymbolParseException($"Cannot parse Java symbol: {raw.Value}");
var ns = match.Groups["pkg"].Value.Replace('/', '.').ToLowerInvariant();
var type = match.Groups["class"].Value.ToLowerInvariant();
var method = match.Groups["method"].Value.ToLowerInvariant();
var signature = ParseJvmDescriptor(match.Groups["desc"].Value);
return BuildCanonical(ns, type, method, signature, raw);
}
private static string ParseJvmDescriptor(string descriptor)
{
// "Ljava/lang/String;" -> "string"
// "[B" -> "byte[]"
var types = new List<string>();
var i = 0;
while (i < descriptor.Length)
{
var (type, consumed) = ParseOneType(descriptor, i);
types.Add(type);
i += consumed;
}
return $"({string.Join(", ", types)})";
}
}
```
### Native Normalization (C++ Demangling)
```csharp
// Input: "_ZN4llvm12DenseMapBaseI..."
// Output: Demangled then normalized
public class NativeSymbolNormalizer : ISymbolNormalizer
{
private readonly IDemangleService _demangler;
public CanonicalSymbol Normalize(RawSymbol raw)
{
var demangled = raw.Value.StartsWith("_Z")
? _demangler.Demangle(raw.Value)
: raw.Value;
// Parse demangled: "llvm::DenseMapBase<...>::operator[](KeyType const&)"
// Simplified: strip templates, extract namespace::class::method
var simplified = StripTemplates(demangled);
var parts = simplified.Split(new[] { "::" }, StringSplitOptions.RemoveEmptyEntries);
// Last part is method(params), rest is namespace
var methodPart = parts.Last();
var nsParts = parts.Take(parts.Length - 1);
var (method, signature) = ParseMethodAndSignature(methodPart);
var ns = string.Join(".", nsParts).ToLowerInvariant();
var type = nsParts.LastOrDefault()?.ToLowerInvariant() ?? "_";
return BuildCanonical(ns, type, method, signature, raw);
}
}
```
---
## Matching Algorithm
### Exact Match
```csharp
if (a.CanonicalId == b.CanonicalId)
return SymbolMatchResult.Exact(1.0);
```
### Fuzzy Match
When exact match fails, apply fuzzy matching with configurable tolerance:
```csharp
public SymbolMatchResult Match(CanonicalSymbol a, CanonicalSymbol b, SymbolMatchOptions options)
{
// 1. Exact match
if (a.CanonicalId == b.CanonicalId)
return SymbolMatchResult.Exact(confidence: 1.0);
// 2. Namespace + Type + Method match (signature may differ due to overloads)
if (a.Namespace == b.Namespace && a.Type == b.Type && a.Method == b.Method)
{
var sigSimilarity = ComputeSignatureSimilarity(a.Signature, b.Signature);
if (sigSimilarity >= options.SignatureThreshold)
return SymbolMatchResult.Fuzzy(confidence: 0.8 + sigSimilarity * 0.15);
}
// 3. Method name match with namespace similarity
if (a.Method == b.Method)
{
var nsSimilarity = ComputeNamespaceSimilarity(a.Namespace, b.Namespace);
var typeSimilarity = ComputeLevenshteinSimilarity(a.Type, b.Type);
if (nsSimilarity >= options.NamespaceThreshold && typeSimilarity >= options.TypeThreshold)
return SymbolMatchResult.Fuzzy(confidence: 0.5 + nsSimilarity * 0.2 + typeSimilarity * 0.2);
}
// 4. No match
return SymbolMatchResult.NoMatch();
}
```

## Golden Corpus
Create test corpus with known symbol pairs:
```json
// test-corpus/symbol-pairs.json
{
"pairs": [
{
"id": "log4j-jndi-lookup",
"symbols": [
{
"source": "JavaAsm",

}
},
{

# SPRINT 009_003: CVE-Symbol Mapping Service
> **Epic:** Hybrid Reachability and VEX Integration
> **Module:** BE (Backend)
> **Status:** DOING (Core complete, extractors pending)
> **Working Directory:** `src/__Libraries/StellaOps.Reachability.Core/CveMapping/`
> **Dependencies:** SPRINT_20260109_009_002
---
## Objective
Implement a service that maps CVE identifiers to vulnerable symbols, enabling the reachability system to answer "which functions are vulnerable for CVE-X?". Mappings are derived from patch analysis, OSV database enrichment, and manual curation.
---
## Prerequisites
Before starting:
- [ ] Complete SPRINT_20260109_009_002 (Symbol Canonicalization)
- [ ] Read `docs/modules/reachability/architecture.md`
- [ ] Read Feedser backport detection docs
- [ ] Understand OSV schema and API
---
## Problem Statement
To determine if a CVE is reachable, we need to know which specific symbols (functions/methods) are vulnerable:
| Challenge | Impact |
|-----------|--------|
| CVE descriptions are prose, not structured | Cannot automatically map CVE to code |
| Patches touch many files | Need to identify vulnerable functions, not all changed code |
| Multiple fix approaches exist | Same CVE may have different vulnerable symbols per version |
| OSV lacks function-level detail | Only provides affected version ranges |
**Solution:** Multi-source mapping with confidence scoring.

## Patch Analysis Algorithm
### Git Diff Extraction
```csharp
public class GitDiffExtractor : IPatchSymbolExtractor
{
public async Task<PatchAnalysisResult> ExtractAsync(

// 1. Fetch diff from git host (GitHub/GitLab/Gitea)
var diff = await FetchDiffAsync(commitUrl, ct);
// 2. Parse unified diff format
var hunks = UnifiedDiffParser.Parse(diff);
// 3. For each hunk, identify changed functions
var changedFunctions = new List<ExtractedFunction>();
foreach (var hunk in hunks)
{
var functions = await DetectFunctionsInHunk(hunk, ct);
changedFunctions.AddRange(functions);
}
// 4. Filter to security-relevant functions
var securityFunctions = FilterSecurityRelevant(changedFunctions);
// 5. Canonicalize symbols
var symbols = securityFunctions

// - Functions that were deleted/modified (not added)
// - Functions with security-related names
// - Functions in security-sensitive files

f.ChangeType is ChangeType.Deleted or ChangeType.Modified &&

# SPRINT 009_004: Runtime Agent Framework
> **Epic:** Hybrid Reachability and VEX Integration
> **Module:** BE (Backend)
> **Status:** DOING (Core framework complete, API/persistence TODO)
> **Working Directory:** `src/Signals/StellaOps.Signals.RuntimeAgent/`
> **Dependencies:** SPRINT_20260109_009_002
---
## Objective
Implement a pluggable runtime agent framework that collects method-level execution traces from running applications. The MVP focuses on .NET EventPipe collection, with extension points for Java, native, and script runtimes.
---
## Prerequisites
Before starting:
- [ ] Complete SPRINT_20260109_009_002 (Symbol Canonicalization)
- [ ] Read `docs/modules/signals/architecture.md`
- [ ] Understand .NET EventPipe/DiagnosticsClient APIs
- [ ] Review existing `RuntimeFactEvent` contract
---
## Problem Statement
To determine runtime reachability, we need to observe which methods actually execute:
| Challenge | Impact |
|-----------|--------|
| Many collection technologies (ETW, eBPF, profilers) | Need abstraction layer |
| High overhead from full instrumentation | Need sampling/low-overhead modes |
| Symbol formats differ from static analysis | Need normalization pipeline |
| Container/Kubernetes environments | Need agent deployment strategy |
**Solution:** Pluggable agent framework with configurable posture levels.

# SPRINT 009_005: VEX Decision Integration
> **Epic:** Hybrid Reachability and VEX Integration
> **Module:** BE (Backend)
> **Status:** DOING (Most features already exist, needs Reachability.Core integration)
> **Working Directory:** `src/Policy/StellaOps.Policy.Engine/Vex/`
> **Dependencies:** SPRINT_20260109_009_001, SPRINT_20260109_009_003
---
## Objective
Enhance the VEX decision emission pipeline to incorporate hybrid reachability evidence, producing OpenVEX documents with the `x-stellaops-evidence` extension that provides full audit trail for reachability-based verdicts.
---
## Prerequisites
Before starting:
- [ ] Complete SPRINT_20260109_009_001 (Reachability Core)
- [ ] Complete SPRINT_20260109_009_003 (CVE-Symbol Mapping)
- [ ] Read `docs/modules/vex-lens/architecture.md`
- [ ] Read existing `IVexDecisionEmitter` implementation
- [ ] Understand OpenVEX specification
---
## Problem Statement
Current VEX emission lacks reachability evidence:
| Current State | Gap |
|---------------|-----|
| VEX status based on vendor statements | No code-level evidence |
| Justifications are manual | Not derived from analysis |
| No confidence scores | All verdicts equal weight |
| No audit trail | Cannot verify decision |
**Solution:** Reachability-aware VEX emitter with evidence extension.

## Integration with Existing Panel
Update `tabbed-evidence-panel.component.ts` to include reachability tab:
```typescript
// In tabbed-evidence-panel.component.ts
import { ReachabilityTabComponent } from './reachability-tab.component';
@Component({
// ...
imports: [
// ... existing imports
ReachabilityTabComponent
],
template: `
<!-- ... existing template ... -->
<!-- Add Reachability tab -->
<button
role="tab"
[attr.aria-selected]="activeTab() === 'reachability'"
(click)="setActiveTab('reachability')"
>
Reachability
@if (reachabilityState(); as state) {
<app-lattice-state-badge [state]="state" [compact]="true" />
}
</button>
<!-- Tab content -->
@if (activeTab() === 'reachability') {
<app-reachability-tab
[findingId]="findingId()"
[artifactDigest]="artifactDigest()"
[cveId]="cveId()"
/>
}
`
})
export class TabbedEvidencePanelComponent {
// Add reachability state signal
readonly reachabilityState = signal<LatticeState | null>(null);
}
```

# SPRINT INDEX: GitHub Code Scanning Integration
> **Epic:** Platform Integrations
> **Batch:** 010
> **Status:** Planning
> **Created:** 09-Jan-2026
---
## Overview
This sprint batch implements complete GitHub Code Scanning integration via SARIF 2.1.0, enabling StellaOps Scanner findings to appear natively in GitHub's Security tab.
### Business Value
- **Zero Custom UI:** GitHub renders findings, annotations, and PR decorations
- **Native Integration:** Findings appear alongside Dependabot/CodeQL alerts
- **Alert Management:** GitHub's existing dismiss/reopen workflow
- **PR Blocking:** Branch protection rules can gate on scan results
- **Enterprise Ready:** GitHub.com + GitHub Enterprise Server support

## Fingerprint Strategy
### Primary Fingerprint (stellaops/v1)
```
SHA-256(ruleId + "|" + componentPurl + "|" + vulnId + "|" + artifactDigest)
```
### Partial Fingerprints
For GitHub fallback when source unavailable:
- `primaryLocationLineHash`: SHA-256 of trimmed line content
### Implementation
```csharp
public class FingerprintGenerator : IFingerprintGenerator
{
public string GeneratePrimary(Finding finding, FingerprintStrategy strategy)
{
var input = strategy switch
{
FingerprintStrategy.Standard => string.Join("|",
GetRuleId(finding),
finding.ComponentPurl ?? "",
finding.VulnerabilityId ?? "",
finding.ArtifactDigest ?? ""),
_ => throw new ArgumentOutOfRangeException(nameof(strategy))
};
return ComputeSha256(input);
}
private static string GetRuleId(Finding finding)
{
return finding.Type switch
{
FindingType.Vulnerability => GetVulnRuleId(finding.Severity),
FindingType.Secret => "STELLA-SEC-001",
FindingType.SupplyChain => "STELLA-SC-001",
FindingType.BinaryHardening => "STELLA-BIN-001",
_ => "STELLA-UNKNOWN"
};
}
private static string GetVulnRuleId(Severity severity) => severity switch
{
Severity.Critical => "STELLA-VULN-001",
Severity.High => "STELLA-VULN-002",
Severity.Medium => "STELLA-VULN-003",
Severity.Low => "STELLA-VULN-004",
_ => "STELLA-VULN-004"
};
}
```
---
## Severity Mapping
```csharp
public static class SeverityMapper
{
public static SarifLevel MapToSarifLevel(
Severity severity,
ReachabilityState? reachability = null)
{
// Reachable vulnerabilities escalate to error
if (reachability is ReachabilityState.RuntimeObserved
or ReachabilityState.ConfirmedReachable)
{
if (severity >= Severity.Medium)
return SarifLevel.Error;
}
return severity switch
{
Severity.Critical => SarifLevel.Error,
Severity.High => SarifLevel.Error,
Severity.Medium => SarifLevel.Warning,
Severity.Low => SarifLevel.Note,
Severity.Info => SarifLevel.Note,
_ => SarifLevel.None
};
}
public static string GetSecuritySeverity(double cvssScore)
{
// GitHub uses security-severity for ordering
return cvssScore.ToString("F1", CultureInfo.InvariantCulture);
}
}
```
---
## StellaOps Properties Extension
SARIF `properties` bag for StellaOps-specific data:
```json
{
"properties": {
"stellaops.finding.id": "f47ac10b-58cc-4372-a567-0e02b2c3d479",
"stellaops.component.purl": "pkg:maven/org.apache.logging.log4j/log4j-core@2.14.1",
"stellaops.vulnerability.cve": "CVE-2021-44228",
"stellaops.vulnerability.cvss": 10.0,
"stellaops.vulnerability.severity": "critical",
"stellaops.vulnerability.epss": 0.975,
"stellaops.vulnerability.kev": true,
"stellaops.reachability.state": "RuntimeObserved",
"stellaops.reachability.confidence": 0.92,
"stellaops.vex.status": "affected",
"stellaops.evidence.uris": [
"stella://reachgraph/blake3:abc123"
]
}
}
```
---
## API Endpoint
```csharp
public static class SarifExportEndpoints
{
public static void MapSarifEndpoints(this IEndpointRouteBuilder app)
{
var group = app.MapGroup("/v1/scans/{scanId}/exports")
.RequireAuthorization("scanner:read");
group.MapGet("/sarif", ExportSarif)
.WithName("ExportScanSarif")
.Produces<string>(StatusCodes.Status200OK, "application/sarif+json");
}
private static async Task<IResult> ExportSarif(
Guid scanId,
[FromQuery] string? minSeverity,
[FromQuery] bool pretty = false,
[FromQuery] bool includeReachability = true,
ISarifExportService sarifService,
IFindingsService findingsService,
CancellationToken ct)
{
var findings = await findingsService.GetByScanIdAsync(scanId, ct);
var options = new SarifExportOptions
{
ToolVersion = GetToolVersion(),
MinimumSeverity = ParseSeverity(minSeverity),
IncludeReachability = includeReachability,
IndentedJson = pretty
};
var json = await sarifService.ExportToJsonAsync(findings, options, ct);
return Results.Content(json, "application/sarif+json");
}
}
```
---
## Determinism Requirements
1. **Sorted results:** By (ruleId, location.uri, location.region.startLine, fingerprint)
2. **Sorted rules:** By rule ID
3. **Sorted properties:** Keys sorted lexicographically
4. **No nulls:** Omit null properties
5. **Immutable collections:** Use `ImmutableArray`, `ImmutableDictionary`
6. **Time injection:** `TimeProvider` for timestamps

## API Endpoints
### GitHub Integration Endpoints
```csharp
public static class GitHubCodeScanningEndpoints
{
public static void MapGitHubEndpoints(this IEndpointRouteBuilder app)
{
var group = app.MapGroup("/v1/integrations/github")
.RequireAuthorization("integrations:write");
// Upload scan to GitHub
group.MapPost("/repos/{owner}/{repo}/upload-sarif", UploadSarif)
.WithName("UploadSarifToGitHub");
// Get upload status
group.MapGet("/repos/{owner}/{repo}/sarifs/{sarifId}/status", GetUploadStatus)
.WithName("GetSarifUploadStatus");
// List alerts
group.MapGet("/repos/{owner}/{repo}/alerts", ListAlerts)
.RequireAuthorization("integrations:read")
.WithName("ListCodeScanningAlerts");
}
}
```
---
## GitHub Enterprise Support
Extend existing GHES support in connector:
```csharp
public class GitHubCodeScanningClient
{
private readonly string _apiBase;
public GitHubCodeScanningClient(GitHubConnectorOptions options)
{
_apiBase = options.IsEnterprise
? $"https://{options.Hostname}/api/v3"
: "https://api.github.com";
}
}
```
---
## Error Handling
### Retry Policy
```csharp
services.AddHttpClient<IGitHubCodeScanningClient, GitHubCodeScanningClient>()
.AddPolicyHandler(GetRetryPolicy())
.AddPolicyHandler(GetRateLimitPolicy());
static IAsyncPolicy<HttpResponseMessage> GetRetryPolicy()
{
return HttpPolicyExtensions
.HandleTransientHttpError()
.OrResult(r => r.StatusCode == HttpStatusCode.TooManyRequests)
.WaitAndRetryAsync(3, retryAttempt =>
TimeSpan.FromSeconds(Math.Pow(2, retryAttempt)));
}
```
### Rate Limit Handling
```csharp
private async Task HandleRateLimitAsync(HttpResponseMessage response, CancellationToken ct)
{
if (response.StatusCode == HttpStatusCode.Forbidden)
{
if (response.Headers.TryGetValues("X-RateLimit-Remaining", out var remaining))
{
if (int.TryParse(remaining.FirstOrDefault(), out var rem) && rem == 0)
{
if (response.Headers.TryGetValues("X-RateLimit-Reset", out var reset))
{
var resetTime = DateTimeOffset.FromUnixTimeSeconds(
long.Parse(reset.First()));
var delay = resetTime - DateTimeOffset.UtcNow;
if (delay > TimeSpan.Zero && delay < TimeSpan.FromMinutes(5))
{
_logger.LogWarning("Rate limited, waiting {Delay}", delay);
await Task.Delay(delay, ct);
}
}
}
}
}
}
```

# SPRINT INDEX: AI Moats - Defensible AI-Native Security Platform
> **Epic:** Evidence-First AI with Cryptographic Trust
> **Batch:** 011
> **Status:** Planning
> **Created:** 09-Jan-2026
> **Source Advisory:** `docs/product/advisories/08-Jan-2026 - AI moats.md`
---
## Executive Summary
This sprint batch transforms StellaOps from "security platform with AI features" to "AI-native security platform with defensible moats." The key insight: **AI outputs must become first-class artifacts in the attestation chain**, not ephemeral chat responses.
### Strategic Differentiation
| Competitor Approach | StellaOps Approach |
|--------------------|--------------------|
| Chat-only AI | AI outputs as signed artifacts |
| Generic RAG | Security-specific grounding with evidence links |
| Role-based permissions | K4 lattice policy gates |
| Ephemeral conversations | Auditable Runs with deterministic replay |
| Learning from chat logs | Learning from verified decision outcomes |
### Business Value
- **Trust by construction:** Every AI claim cryptographically linked to evidence
- **Compliance-ready:** Full audit trail for AI-assisted decisions
- **Institutional learning:** Outcomes feed back into decision support
- **Reproducibility:** AI sessions can be replayed for verification
- **Air-gap compatible:** All features work offline

## Objective
Create cryptographically signed attestations for AI outputs, making every AI-generated claim, explanation, and recommendation a verifiable artifact in the same trust chain as SBOMs and VEX statements.
### Why This Matters
| Without AI Attestations | With AI Attestations |
|------------------------|---------------------|
| "The AI said it's safe" | Signed claim with evidence URIs |
| Ephemeral chat history | Immutable attestation in ledger |
| Cannot prove AI reasoning | Deterministic replay possible |
| Audit gap for AI decisions | Full provenance chain |

## Configuration
```yaml
AdvisoryAI:
Attestation:
Enabled: true
SigningKeyId: "ai-attestation-key"
StoreUnsigned: false # Only store signed attestations
PromptTemplates:
Path: "/etc/stellaops/prompt-templates/"
AutoRegister: true
```
---
## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Per-claim vs per-turn attestations | Per-claim provides finer granularity but more storage |
| Signing key rotation | Need key rotation strategy |
| Attestation storage growth | Retention policy needed |
| Determinism with LLM variations | Content digest may vary; attestation captures what was said |

## Objective
Connect OpsMemory (institutional decision memory) to AdvisoryAI Chat, enabling the AI to surface relevant past decisions and automatically record new decisions with outcomes.
### Why This Matters
| Current State | Target State |
|---------------|--------------|
| OpsMemory isolated from Chat | Past decisions surface in chat context |
| Decisions recorded manually | Decisions auto-recorded from chat actions |
| No feedback loop | Outcomes improve future suggestions |
| Generic suggestions | Security-specific similarity matching |

**System Prompt Addition:**
```
## Previous Similar Decisions
Based on your organization's decision history, here are relevant past decisions:
{{#each similarDecisions}}
### {{cveId}} ({{similarity}}% similar)
- **Decision:** {{action}}
- **Outcome:** {{outcome}}
- **Rationale:** {{rationale}}

## Objective
Implement the "Run" concept - an auditable container for AI interactions that captures the complete lifecycle from initial query through tool calls, artifact generation, and approvals.
### Why This Matters (from ADVISORY-AI-000)
> "Chat is not auditable, repeatable, actionable with guardrails, or collaborative."
The Run concept transforms ephemeral chat into:
- **Auditable:** Every interaction logged with timestamps
- **Repeatable:** Deterministic replay possible
- **Actionable:** Artifacts produced (not just text)
- **Collaborative:** Handoffs, approvals, shared context
---
## Working Directory
- `src/AdvisoryAI/StellaOps.AdvisoryAI/Runs/` (new)
- `src/AdvisoryAI/StellaOps.AdvisoryAI.WebService/Endpoints/RunEndpoints.cs` (new)
- `src/Web/StellaOps.Web/src/app/features/advisory-ai/runs/` (new)
- `src/__Libraries/__Tests/StellaOps.AdvisoryAI.Tests/Runs/` (new)
---
## Prerequisites
- Existing: `ConversationService` - Chat infrastructure
- Existing: `ActionProposalParser` - Action extraction
- Existing: `GroundingValidator` - Evidence validation
- Required: AI Attestations (011_001) for Run attestation

Enabled: true
AutoCreate: true # Auto-create from first conversation turn
RetentionDays: 90
AttestOnComplete: true
ReplayEnabled: true
Timeline:
MaxEventsPerRun: 1000
ContentDigestAlgorithm: sha256
```
---
## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Auto-create vs explicit | Auto-create reduces friction but may create many short-lived Runs |
| Timeline event storage | Append-only for audit; may grow large |
| Replay determinism | LLM responses vary; capture digest, not expect exact match |
| Run retention | Need retention policy to manage storage |
---
## Execution Log

> **Parent:** [SPRINT_20260109_011_000_INDEX](./SPRINT_20260109_011_000_INDEX_ai_moats.md)
> **Status:** TODO

## Objective
Connect AI-proposed actions to the Policy Engine's K4 lattice for governance-aware automation. Move beyond simple role checks to VEX-aware policy gates with approval workflows.
### Why This Matters (from ADVISORY-AI-002)
> "The main blocker to 'AI that acts' is governance: wrong environment, insufficient permission, missing approvals, non-idempotent actions, unclear accountability."
Current state: ActionProposalParser checks roles.
Target state: Full policy evaluation with:
- K4 lattice integration for VEX-aware decisions
- Approval workflows for high-risk actions
- Idempotency tracking
- Action audit ledger
---
## Working Directory
- `src/AdvisoryAI/StellaOps.AdvisoryAI/Actions/` (new subdirectory)
- `src/Policy/StellaOps.Policy.Engine/Actions/` (integration)
- `src/__Libraries/__Tests/StellaOps.AdvisoryAI.Tests/Actions/` (new)
---
## Prerequisites
- Existing: `ActionProposalParser` - Action extraction
- Existing: `Policy.Engine` - K4 lattice logic
- Existing: `Policy.ReviewWorkflowService` - Approval workflows
- Required: AI Runs (011_003) for action attachment

# Sprint SPRINT_20260109_011_005_LB - Evidence Pack Artifacts
> **Parent:** [SPRINT_20260109_011_000_INDEX](./SPRINT_20260109_011_000_INDEX_ai_moats.md)
> **Status:** TODO
> **Created:** 09-Jan-2026
> **Module:** LB (Library) + BE (Backend)
> **Depends On:** SPRINT_20260109_011_001_LB (AI Attestations), SPRINT_20260109_011_003_BE (AI Runs)
---
## Objective
Create the Evidence Pack as a first-class artifact - a shareable, DSSE-signed bundle of evidence supporting an AI recommendation or security decision.
### Why This Matters (from ADVISORY-AI-001)
> "An answer without evidence is a liability. LLMs are persuasive even when wrong."
Evidence Packs transform ephemeral AI responses into:
- **Shareable:** Export for audit, compliance, incident response
- **Verifiable:** DSSE-signed with content digests
- **Linked:** All evidence URIs resolvable
- **Complete:** Contains everything needed to verify a claim
---
## Working Directory
- `src/__Libraries/StellaOps.Evidence.Pack/` (new)
- `src/AdvisoryAI/StellaOps.AdvisoryAI/Evidence/` (integration)
- `src/Web/StellaOps.Web/src/app/features/evidence-pack/` (new)
- `src/__Libraries/__Tests/StellaOps.Evidence.Pack.Tests/` (new)
---
## Prerequisites
- Existing: `EvidenceLocker` - Evidence storage
- Existing: `GroundingValidator` - Evidence extraction from AI responses
- Required: AI Attestations (011_001) for signing
- Required: AI Runs (011_003) for attachment
