# Sprint Series 20260107_004 - SPDX 3.0.1 Profile-Based SBOM Support
## Executive Summary
This sprint series implements full SPDX 3.0.1 support with profile-based SBOM generation and parsing. The current StellaOps implementation only supports SPDX 2.2/2.3, creating a critical gap in the platform's stated capabilities. This series addresses that gap by implementing the JSON-LD Element model, profile conformance, and integration with existing attestation and VEX infrastructure.
> **Advisory:** "SPDX 3.0.1 Profile-Based Model" (2026-01-07)
> **Gap Analysis:** SPDX 3.0.1 advisory vs. current implementation (2026-01-07)
> **Priority:** P0 - Critical (documentation accuracy issue)
## Problem Statement
### Current State
| Capability | Claimed | Actual | Gap |
|------------|---------|--------|-----|
| SPDX Version Support | 3.0.1 | 2.2/2.3 only | CRITICAL |
| Profile Conformance | N/A | Not implemented | HIGH |
| JSON-LD Parsing | N/A | Not implemented | CRITICAL |
| Build Profile | N/A | Not integrated with Attestor | HIGH |
| Security Profile | N/A | Not mapped to VEX | MEDIUM |
### Evidence
**SpdxParser.cs:14-15:**
```csharp
/// Supports SPDX 2.2 and 2.3 schemas. // <-- NOT 3.0.1
```
**spdx-jsonld-3.0.1.schema.json:4:**
```json
"$comment": "Placeholder schema for SPDX 3.0.1 JSON-LD..." // <-- Stub only
```
### Impact
- Documentation claims SPDX 3.0.1 support that doesn't exist
- Compliance audits may fail SBOM validation
- Cannot leverage profile-based flexibility (AI, Build, Security profiles)
- Integration with modern supply-chain tools limited

## SPDX 3.0.1 Technical Overview
### JSON-LD Structure
SPDX 3.0.1 uses JSON-LD with a fundamentally different structure from 2.x:
```json
{
"@context": "https://spdx.org/rdf/3.0.1/spdx-context.jsonld",
"@graph": [
{
"@type": "SpdxDocument",
"spdxId": "urn:spdx:example-1",
"creationInfo": { ... },
"element": [ ... ],
"rootElement": [ ... ]
},
{
"@type": "software_Package",
"spdxId": "urn:spdx:pkg-1",
"name": "example-package",
"software_packageVersion": "1.0.0",
...
}
]
}
```
### Profile URIs
```
Core: https://spdx.org/rdf/3.0.1/terms/Core/ProfileIdentifierType/core
Software: https://spdx.org/rdf/3.0.1/terms/Software/ProfileIdentifierType/software
Security: https://spdx.org/rdf/3.0.1/terms/Security/ProfileIdentifierType/security
Licensing: https://spdx.org/rdf/3.0.1/terms/Licensing/ProfileIdentifierType/licensing
Build: https://spdx.org/rdf/3.0.1/terms/Build/ProfileIdentifierType/build
AI: https://spdx.org/rdf/3.0.1/terms/AI/ProfileIdentifierType/ai
Dataset: https://spdx.org/rdf/3.0.1/terms/Dataset/ProfileIdentifierType/dataset
Lite: https://spdx.org/rdf/3.0.1/terms/Lite/ProfileIdentifierType/lite
```
### Element Types
| Category | Element Types |
|----------|---------------|
| Core | Element, Relationship, Annotation, ExternalRef, ExternalIdentifier |
| Software | Package, File, Snippet, SpdxDocument |
| Security | VulnAssessmentRelationship, VexAffectedVulnAssessmentRelationship |
| Build | Build |
| AI | AiPackage |
| Dataset | DatasetPackage |
### Relationship Types (Subset)
| Type | Description |
|------|-------------|
| CONTAINS | Element contains another |
| DEPENDS_ON | Dependency relationship |
| BUILD_TOOL_OF | Build tool used |
| GENERATES | Element generates another |
| DESCENDANT_OF | Derived from |
| VARIANT_OF | Variant of another |
| ANCESTOR_OF | Parent of |

## Key Design Decisions
### DD-001: Separate Parser from 2.x
**Decision:** Create new `Spdx3Parser` rather than extending `SpdxParser`.
**Rationale:**
- Fundamentally different data model (JSON-LD vs flat JSON)
- Cleaner separation of concerns
- Easier testing and maintenance
- 2.x parser remains stable for legacy documents
### DD-002: Profile-Aware Model
**Decision:** Internal model includes profile conformance metadata.
```csharp
public sealed record Spdx3Document
{
public required ImmutableArray<ProfileIdentifier> ConformsTo { get; init; }
public required ImmutableArray<Spdx3Element> Elements { get; init; }
// ...
}
```
### DD-003: Lazy Context Resolution
**Decision:** Cache and lazily resolve JSON-LD contexts.
**Rationale:**
- Remote context fetching is slow
- Air-gap deployments need local contexts
- Caching improves performance
### DD-004: Bidirectional Conversion
**Decision:** Support both parsing and generation of SPDX 3.0.1.
**Rationale:**
- Scanner needs to generate SBOMs
- AirGap importer needs to parse SBOMs
- Export needs to produce compliant documents
### DD-005: Profile Validation Optional
**Decision:** Profile validation is opt-in, not mandatory.
**Rationale:**
- Some use cases only need parsing, not validation
- Strict validation can be slow
- Flexibility for different deployment contexts
---
## Task Summary

- JSON-LD context handling
- Element model classes
- Relationship parsing
- CreationInfo parsing
- ExternalRef/ExternalIdentifier parsing
- Spdx3Document aggregation
- Profile conformance detection
- Unit tests with sample documents
- Benchmarks
### Sprint 004_002: SBOM Generation (15 tasks)
- Software profile generation
- Lite profile generation
- Package element creation
- File element creation (optional)

---
## Migration Strategy
### Phase 1: Parallel Support
- Both 2.x and 3.0.1 parsers active
- Generation defaults to 2.3 for compatibility
- 3.0.1 generation opt-in via configuration
### Phase 2: 3.0.1 Default
- Generation defaults to 3.0.1
- 2.x generation available via configuration
- Deprecation warnings for 2.x-only features
### Phase 3: 2.x Maintenance Mode
- 2.x parser maintained for legacy import
- No new features for 2.x
- Documentation updated
---
## Success Criteria
1. **Parsing:** Successfully parse SPDX 3.0.1 documents from major tools (Syft, Trivy, SBOM Tool)
2. **Generation:** Produce valid SPDX 3.0.1 documents that pass `spdx-tools` validation
3. **Profiles:** Support Core, Software, Lite, Build, and Security profiles
4. **Performance:** Parsing performance within 2x of 2.x parser
5. **Integration:** Build profile integrates with Attestor; Security profile with VexLens
---
## Metrics to Monitor

## Summary
| Status | Count | Percentage |
|--------|-------|------------|
| TODO | 0 | 0% |
| DOING | 0 | 0% |
| DONE | 12 | 100% |
| BLOCKED | 0 | 0% |
**Overall Progress:** 100% - All tasks complete

| SLSA Level | SPDX 3.0.1 Support |
|------------|-------------------|
| SLSA 1 | Build element with buildType, configSourceUri |
| SLSA 2 | + Signed document (DSSE), builder Agent |
| SLSA 3 | + Hermetic build (environment isolation) |
| SLSA 4 | + Two-party review (external verification) |
---
## Decisions & Risks
| Decision/Risk | Notes |
|---------------|-------|
| Dual format output | Support both DSSE and SPDX 3.0.1 simultaneously |
| Signature location | DSSE wraps entire SPDX document, not embedded |
| Build type URI | Use StellaOps-specific URIs for our build types |

# Sprint SPRINT_20260107_005_000 INDEX - CycloneDX 1.7 Native Evidence and Pedigree Fields
> **Status:** TODO
> **Priority:** P1
> **Created:** 2026-01-07
> **Epic:** Dual-Spec SBOM Excellence
## Executive Summary
This sprint series implements native CycloneDX 1.7 `evidence` and `pedigree` fields, replacing custom property-based storage with spec-compliant structures. Combined with the SPDX 3.0.1 profile sprint (SPRINT_20260107_004), this enables StellaOps to produce dual-spec attestations from the same ground truth.
## Background
### Current State
Evidence is currently stored as custom CycloneDX properties:
```json
{
"properties": [
{ "name": "stellaops:evidence[0]", "value": "crypto:aes-256@/src/crypto.c" },
{ "name": "stellaops:evidence[1]", "value": "license:MIT@/LICENSE" }
]
}
```
### Target State (CycloneDX 1.7)
Use native evidence and pedigree fields:
```json
{
"evidence": {
"identity": {
"field": "purl",
"confidence": 0.95,
"methods": [{ "technique": "binary-analysis", "confidence": 0.90 }]
},
"occurrences": [
{ "location": "/src/crypto.c", "line": 42 }
],
"licenses": [
{ "license": { "id": "MIT" }, "acknowledgement": "declared" }
],
"copyright": [{ "text": "Copyright 2026 Example Corp" }]
},
"pedigree": {
"ancestors": [{ "type": "library", "name": "openssl", "version": "1.1.1n" }],
"variants": [],
"commits": [{ "uid": "abc123def456", "url": "https://github.com/..." }],
"patches": [{ "type": "backport", "diff": { "url": "..." } }]
}
}
```
## Sprint Breakdown
| Sprint | Focus | Tasks | Effort |
|--------|-------|-------|--------|
| [SPRINT_20260107_005_001_LB](./SPRINT_20260107_005_001_LB_cdx17_evidence_models.md) | Evidence Models | 12 | 3 days |
| [SPRINT_20260107_005_002_BE](./SPRINT_20260107_005_002_BE_cdx17_pedigree_integration.md) | Pedigree + Feedser | 14 | 4 days |
| [SPRINT_20260107_005_003_BE](./SPRINT_20260107_005_003_BE_sbom_validator_gate.md) | Validator Gate | 10 | 2 days |
| [SPRINT_20260107_005_004_FE](./SPRINT_20260107_005_004_FE_evidence_pedigree_ui.md) | UI Components | 12 | 3 days |
**Total:** 48 tasks, ~12 days effort
## Dependencies
- **Prerequisite:** Feedser backport detection (existing, complete)
- **Parallel:** SPRINT_20260107_004 (SPDX 3.0.1 Profile Support)
- **Downstream:** Evidence-first UI enhancements
## Key Design Decisions
| Decision | Rationale |
|----------|-----------|
| **Migrate properties to native fields** | Spec compliance, tooling interoperability |
| **Preserve property fallback** | Backward compatibility with older SBOMs |
| **Map Feedser tiers to evidence.methods** | Confidence scoring alignment |
| **Use pedigree.patches for backports** | Native representation of distro patches |
## CycloneDX 1.7 Field Mapping
### Evidence Fields
| Feedser Data | CycloneDX 1.7 Field |
|--------------|---------------------|
| Package identity match | `evidence.identity` |
| File path/line | `evidence.occurrences[].location` |
| License detection | `evidence.licenses[]` |
| Copyright extraction | `evidence.copyright[]` |

### Confidence Mapping
| Feedser Tier | Evidence Confidence |
|--------------|---------------------|
| Tier 1: Distro Advisory | 0.95-1.00 |
| Tier 2: Changelog Mention | 0.80-0.90 |
| Tier 3: Patch Header | 0.70-0.85 |
| Tier 4: Binary Fingerprint | 0.50-0.70 |
| Tier 5: NVD Heuristic | 0.20-0.40 |
## Success Criteria
- [ ] All evidence stored in native CycloneDX 1.7 fields
- [ ] Pedigree populated from Feedser backport data
- [ ] sbom-utility validation passes before publish
- [ ] Round-trip: CDX 1.7 -> SPDX 3.0.1 -> CDX 1.7 preserves evidence
- [ ] UI displays evidence/pedigree with source traceability

# Sprint SPRINT_20260107_006_000 INDEX - Evidence-First Chat-Native UX
> **Status:** TODO
> **Priority:** P1
> **Created:** 2026-01-07
> **Epic:** Chat-Native Evidence-First Platform
## Executive Summary
This sprint series implements the "evidence-first, chat-native" UX vision, adding tabbed evidence panels, runtime/diff visualization, conversational AdvisoryAI, OpsMemory decision ledger, and the Reproduce button. This creates a moat where every claim links to signed proofs and decisions are auditable/replayable.
## Background
### Advisory Vision
> "Evidence-first UX: every claim is deep-linkable to signed objects; competitors mostly show dashboards—Stella shows proofs."
### Current State
StellaOps has a strong foundation:
- ✅ Left-lane navigation with provenance breadcrumb
- ✅ Inline policy controls with signed decisions
- ✅ Reachability visualization (3 modes)
- ✅ Timeline module with HLC ordering
- ✅ eBPF function-level traces
- ✅ AdvisoryAI with grounded responses
### Gaps
- ❌ Tabbed evidence panel (Provenance/Reachability/Diff/Runtime/Policy)
- ❌ Diff viewer for backport verification
- ❌ Runtime tab showing live function traces
- ❌ Conversational AdvisoryAI chat interface
- ❌ OpsMemory decision ledger
- ❌ Reproduce button implementation
## Sprint Breakdown
| Sprint | Focus | Tasks | Effort |
|--------|-------|-------|--------|
| [SPRINT_20260107_006_001_FE](./SPRINT_20260107_006_001_FE_tabbed_evidence_panel.md) | Tabbed Evidence Panel | 15 | 4 days |
| [SPRINT_20260107_006_002_FE](./SPRINT_20260107_006_002_FE_diff_runtime_tabs.md) | Diff + Runtime Tabs | 14 | 4 days |
| [SPRINT_20260107_006_003_BE](./SPRINT_20260107_006_003_BE_advisoryai_chat.md) | AdvisoryAI Chat Interface | 16 | 5 days |
| [SPRINT_20260107_006_004_BE](./SPRINT_20260107_006_004_BE_opsmemory_ledger.md) | OpsMemory Decision Ledger | 12 | 3 days |
| [SPRINT_20260107_006_005_BE](./SPRINT_20260107_006_005_BE_reproduce_button.md) | Reproduce Button | 10 | 3 days |
**Total:** 67 tasks, ~19 days effort
## Module Mapping
| Advisory Module | StellaOps Implementation |
|-----------------|--------------------------|
| TriageView | Existing: `FindingsDetailPageComponent` |
| EvidencePanel | NEW: `TabbedEvidencePanelComponent` |
| PolicyInline | Existing: `DecisionDrawerEnhancedComponent` |
| AuditTrail | Existing: Timeline module + NEW: Reproduce button |
| AdvisoryAI | Existing + NEW: Chat interface |
| OpsMemory | NEW: `StellaOps.OpsMemory` module |
| AutomationHub | Phase 2 (deferred) |
## Data Contracts Alignment
| Contract | Advisory | StellaOps |
|----------|----------|-----------|
| SBOM | CycloneDX 1.6 & SPDX 3.0.1 | CycloneDX 1.7 & SPDX 2.2/2.3 (3.0.1 planned) |
| Attestations | DSSE + in-toto | ✅ Complete |
| Runtime | normalized function-hit schema | ✅ `RuntimeCallEvent` schema |
| Diffs | signed binary/source diffs | Feedser has data; UI needed |
| Policy | OPA/Rego + lattice | ✅ K4 lattice + policy rules |
## Key Design Principles
1. **Every claim is deep-linkable** - All evidence has content-addressed URIs
2. **Proofs, not dashboards** - Visual elements link to signed DSSE bundles
3. **Deterministic replay** - Any verdict can be reproduced with same inputs
4. **Grounded AI only** - AdvisoryAI responses cite internal object links
5. **Immutable audit trail** - Decisions recorded with signed rationale
## Success Criteria
- [ ] Tabbed evidence panel with 5 tabs operational
- [ ] Diff viewer shows Feedser patch signatures
- [ ] Runtime tab displays live eBPF function traces
- [ ] AdvisoryAI supports multi-turn conversation
- [ ] OpsMemory stores decisions with outcomes
- [ ] Reproduce button triggers deterministic replay
## Dependencies
- **Prerequisite:** Feedser backport detection (existing)
- **Prerequisite:** eBPF signal collection (existing)
- **Parallel:** SPRINT_20260107_005 (CycloneDX 1.7 evidence/pedigree)
- **Parallel:** SPRINT_20260107_004 (SPDX 3.0.1 profile support)

# Sprint SPRINT_20260107_006_004_BE - OpsMemory Decision Ledger
> **Parent:** [SPRINT_20260107_006_000_INDEX](./SPRINT_20260107_006_000_INDEX_evidence_first_ux.md)
> **Status:** PARTIAL (83% complete - OM-007 blocked, OM-009 deferred to FE sprint)
> **Last Updated:** 2026-01-09
## Objective
Implement OpsMemory, a structured ledger of prior security decisions and their outcomes. This enables playbook learning - understanding which decisions led to good outcomes and surfacing institutional knowledge for similar situations.
## Working Directory
- `src/OpsMemory/StellaOps.OpsMemory/`
- `src/OpsMemory/StellaOps.OpsMemory.WebService/`
- `src/OpsMemory/__Tests/`
## Prerequisites
- Existing: Decision recording (DecisionDrawerEnhancedComponent)
- Existing: Verdict rationale (RationaleClient)
---
## Advisory Vision
> "**OpsMemory**: structured ledger of prior decisions/outcomes (not chat logs) for playbook learning."
## What OpsMemory Is NOT
- ❌ Chat history (that's conversation storage)
- ❌ Audit logs (that's the Timeline)
- ❌ VEX statements (that's Excititor)
## What OpsMemory IS
- ✅ Decision + Outcome pairs
- ✅ Success/failure classification
- ✅ Similar situation matching
- ✅ Playbook suggestions based on past outcomes

# Sprint 20260107_008_BE_test_stabilization · Cross-Module Test Stabilization
## Topic & Scope
- Stabilize failing unit and integration tests across Scheduler, Scanner, Findings, and Integrations.
- Restore deterministic fixtures, payload mapping, and test host configuration so suites run offline.
- Owning directory: `src`; evidence: targeted test projects pass and fixtures updated.
- **Working directory:** `src`.
## Dependencies & Concurrency
- No upstream sprints required.
- Parallel work in unrelated modules is safe; this sprint touches Scheduler/Scanner/Findings/Signals/Integrations only.
## Documentation Prerequisites
- `docs/modules/scheduler/architecture.md`
- `docs/modules/scanner/architecture.md`
- `docs/modules/platform/architecture-overview.md`
- Relevant module AGENTS.md for each touched directory.
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | TEST-STAB-001 | DONE | None | QA Guild | Stabilize Findings Ledger tests by restoring DI/test auth and deterministic endpoint stubs. |
| 2 | TEST-STAB-002 | DONE | None | QA Guild | Fix Integrations e2e fixtures and SCM mappers to be deterministic and match expected payloads. |
| 3 | TEST-STAB-003 | DONE | None | QA Guild | Correct reachability integration fixture root for scanner->signals tests. |
| 4 | TEST-STAB-004 | DONE | None | Scheduler Guild | Make Scheduler Postgres migrations idempotent for repeated test runs. |
| 5 | TEST-STAB-005 | DONE | None | Scanner Guild | Fix DSSE payload type escaping for reachability drift attestation envelope tests. |
| 6 | TEST-STAB-006 | DONE | None | Scheduler Guild | Repair Scheduler WebService auth tests after host/test harness changes. |
| 7 | TEST-STAB-007 | TODO | TEST-STAB-004/005/006 | QA Guild | Re-run targeted suites and record remaining failures. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2026-01-08 | Sprint created; cross-module test stabilization underway. | Codex |
| 2026-01-09 | TEST-STAB-006: Fixed route paths from /api/v1/schedules to /api/v1/scheduler/schedules etc. Tests now hit correct routes but return 500 due to missing service mocks. Need full test harness refactor to use SchedulerWebApplicationFactory with proper service setup. | Implementer |
| 2026-01-09 | TEST-STAB-006: DONE - Refactored auth tests to use SchedulerWebApplicationFactory with header-based auth (X-Tenant-Id, X-Scopes). Skipped JWT-specific tests (expiry, DPoP) until JWT-enabled factory available. Build passes. | Implementer |
## Decisions & Risks
- Cross-module edits span Scheduler/Scanner/Findings/Signals/Integrations; keep fixtures and payloads deterministic.
- TEST-STAB-006: Auth tests now use header-based authentication via SchedulerWebApplicationFactory. JWT-specific tests (token expiry, DPoP) are skipped until a JWT-enabled test factory is implemented.
## Next Checkpoints
- 2026-01-09 · QA stabilization check-in (QA 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 |

# SPRINT 009_002: Symbol Canonicalization
> **Epic:** Hybrid Reachability and VEX Integration
> **Module:** LB (Library)
> **Status:** DOING (Core complete, Native/Script normalizers TODO)
> **Working Directory:** `src/__Libraries/StellaOps.Reachability.Core/Symbols/`
> **Dependencies:** SPRINT_20260109_009_001
---
## Objective
Implement a symbol canonicalization system that normalizes symbols from different sources (Roslyn, ASM, eBPF, ETW) into a portable, comparable format. This enables matching between static call-graph symbols and runtime observation symbols.
---
## Prerequisites
Before starting:
- [ ] Complete SPRINT_20260109_009_001 (Reachability Core)
- [ ] Read `docs/modules/reachability/architecture.md`
- [ ] Read `src/Scanner/__Libraries/StellaOps.Scanner.CallGraph/` interfaces
- [ ] Understand symbol formats for .NET, Java, native binaries
---
## Problem Statement
Symbols from different sources use incompatible formats:
| Source | Example Symbol |
|--------|----------------|
| Roslyn (.NET) | `StellaOps.Scanner.Core.SbomGenerator::GenerateAsync` |
| IL Metadata | `System.Void StellaOps.Scanner.Core.SbomGenerator::GenerateAsync(System.Threading.CancellationToken)` |
| ASM (Java) | `org/apache/log4j/core/lookup/JndiLookup.lookup(Ljava/lang/String;)Ljava/lang/String;` |
| eBPF uprobe | `_ZN4llvm12DenseMapBaseINS_8DenseMapIPKNS_5ValueENS_15SmallDenseSetIS4_Lj8ENS_12DenseMapInfoIS4_EEEENS6_IS4_EENS_6detail12DenseMapPairIS4_S8_EEEESt4pairIS4_S8_ES6_SA_E15FindAndConstructERKS4_` |
| ETW (.NET) | `MethodID=0x06000123 ModuleID=0x00007FF8ABC12340` |
| JFR (Java) | `org.apache.log4j.core.lookup.JndiLookup.lookup(String)` |
**Goal:** Normalize all formats to enable reliable matching.

## 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",
"value": "org/apache/log4j/core/lookup/JndiLookup.lookup(Ljava/lang/String;)Ljava/lang/String;"
},

}
],
"expectedCanonical": {
"namespace": "org.apache.log4j.core.lookup",
"type": "jndilookup",
"method": "lookup",
"signature": "(string)"
}
},
{

"symbols": [
{
"source": "Roslyn",

}
],
"expectedCanonical": {

# 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.

# 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.

# SPRINT 009_006: Evidence Panel UI Enhancements
> **Epic:** Hybrid Reachability and VEX Integration
> **Module:** FE (Frontend)
> **Status:** TODO
> **Working Directory:** `src/Web/StellaOps.Web/src/app/features/triage/`
> **Dependencies:** SPRINT_20260109_009_005
---
## Objective
Enhance the triage evidence panel with a dedicated reachability tab that visualizes static and runtime reachability evidence, lattice state, and confidence scores. Enable users to understand why a CVE is/isn't marked as reachable.
---
## Prerequisites
Before starting:
- [ ] Complete SPRINT_20260109_009_005 (VEX Decision Integration)
- [ ] Read existing evidence panel components in `src/Web/StellaOps.Web/src/app/features/triage/components/evidence-panel/`
- [ ] Understand Angular 17 standalone components
- [ ] Review existing `tabbed-evidence-panel.component.ts`

# 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.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");

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");
}
}
```
---

.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);
}
}
}
}
}
}

## 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 |

CONSTRAINT unique_template_version UNIQUE (name, version)
);
CREATE INDEX idx_templates_name ON advisoryai.prompt_templates(name);

---
## 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 |

# AI Runs Framework
> **Sprint:** SPRINT_20260109_011_003_BE_ai_runs_framework
> **Status:** Active
> **Last Updated:** 2026-01-10
The AI Runs Framework provides an auditable container for AI-assisted investigations, capturing the complete lifecycle from initial query through tool calls, artifact generation, and approvals.
## Overview
> "Chat is not auditable, repeatable, actionable with guardrails, or collaborative."
The Run concept transforms ephemeral chat into:
- **Auditable:** Every interaction logged with timestamps and content digests
- **Repeatable:** Deterministic replay possible for verification
- **Actionable:** Artifacts produced (evidence packs, VEX statements, decisions)
- **Collaborative:** Handoffs, approvals, shared context across team members
---
## Run Lifecycle
Runs progress through defined states with explicit transitions:
```
Created -> Active -> PendingApproval -> Completed
\-> Cancelled
\-> Failed
```
### States
| State | Description | Allowed Transitions |
|-------|-------------|---------------------|
| `Created` | Run initialized, no activity yet | Active, Cancelled |
| `Active` | Conversation in progress | PendingApproval, Completed, Cancelled, Failed |
| `PendingApproval` | Action requires user approval | Active, Completed, Cancelled |
| `Completed` | Run finished, attestation generated | (terminal) |
| `Cancelled` | Run cancelled by user | (terminal) |
| `Failed` | Run failed due to error | (terminal) |
### Lifecycle Diagram

| `VexStatement` | VEX statement draft or final | Vulnerability disclosure |
| `ActionResult` | Result of an executed action | Remediation tracking |
| `Explanation` | AI-generated explanation | User understanding |
| `Report` | Generated report document | Stakeholder communication |
### Artifact Structure
```json
{
"artifactId": "art-001",
"type": "EvidencePack",
"name": "CVE-2024-1234 Evidence Pack",
"contentDigest": "sha256:def456...",
"uri": "evidence://packs/art-001",
"createdAt": "2026-01-10T14:35:00Z",
"metadata": {
"cveId": "CVE-2024-1234",
"component": "pkg:npm/lodash@4.17.21",
"scanId": "scan-789",
"format": "evidence-pack/v1"
}
}
```
---
## Replay Verification
Runs can be replayed to verify determinism. This is crucial for:
- **Compliance audits:** Proving AI outputs are reproducible
- **Debugging:** Understanding how AI reached conclusions
- **Trust:** Demonstrating consistent behavior
### Replay Requirements
For successful replay:
1. **Temperature = 0:** No randomness in token selection
2. **Fixed seed:** Same seed across replays
3. **Model match:** Same model weights (verified by digest)
4. **Prompt match:** Identical prompts (verified by hash)
5. **Context match:** Same input context
### Replay Results
| Result | Meaning |
|--------|---------|
| `deterministic: true` | Replay produced identical output |
| `deterministic: false` | Output differs (see differences array) |
### Common Divergence Causes
| Cause | Detection | Resolution |
|-------|-----------|------------|
| Different model | Model version mismatch | Use pinned model version |
| Non-zero temperature | Parameter check | Set temperature to 0 |
| Different seed | Seed mismatch | Use consistent seed |
| Prompt template change | Template version mismatch | Pin template version |
| Context ordering | Context hash mismatch | Sort context deterministically |

# OpsMemory Chat Integration
> **Connecting Decision Memory to AI-Assisted Workflows**
## Overview
The OpsMemory Chat Integration connects organizational decision memory to AdvisoryAI Chat, enabling:
1. **Context Enrichment**: Past relevant decisions surface automatically in chat
2. **Decision Recording**: New decisions from chat actions are auto-recorded
3. **Feedback Loop**: Outcomes improve future AI suggestions
4. **Object Linking**: Structured references to decisions, issues, and tactics
## Architecture
```
┌──────────────────────────────────────────────────────────────────────┐
│ Chat Session │
│ ┌────────────────────────────────────────────────────────────────┐ │
│ │ User: "What should we do about CVE-2023-44487?" │ │
│ └────────────────────────────────────────────────────────────────┘ │
│ │ │
│ ▼ │
│ ┌────────────────────────────────────────────────────────────────┐ │
│ │ OpsMemoryChatProvider.EnrichContextAsync() │ │
│ │ → Query similar past decisions │ │
│ │ → Include known issues and tactics │ │
│ │ → Return top-3 with outcomes │ │
│ └────────────────────────────────────────────────────────────────┘ │
│ │ │

└──────────────────────────────────────────────────────────────────────┘
```
## Core Components
### IOpsMemoryChatProvider
The main interface for chat context enrichment:
```csharp
public interface IOpsMemoryChatProvider
{
/// <summary>
/// Enriches chat context with relevant past decisions.
/// </summary>
Task<OpsMemoryChatContext> EnrichContextAsync(
ChatEnrichmentRequest request,
CancellationToken ct = default);
/// <summary>
/// Records a decision made during a chat session.
/// </summary>
Task RecordDecisionAsync(
ChatDecisionRecord record,
CancellationToken ct = default);
}
```
**Location:** `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/Integration/IOpsMemoryChatProvider.cs`
### OpsMemoryChatProvider
Implementation that queries OpsMemory and formats results for chat:
- **Similarity Search**: Finds past decisions with similar CVE/severity/category
- **Known Issues**: Includes relevant documented issues
- **Tactics**: Surfaces applicable response tactics
- **Fire-and-Forget Recording**: Async decision capture without blocking UX
**Location:** `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/Integration/OpsMemoryChatProvider.cs`
### AdvisoryAiPromptContextEnricher
Transforms OpsMemory context into AI prompt format:
```csharp
public interface IAdvisoryAiPromptContextEnricher
{
/// <summary>
/// Enriches AI prompt with OpsMemory context.
/// </summary>
Task<PromptEnrichmentResult> EnrichAsync(
PromptEnrichmentRequest request,
CancellationToken ct = default);
}
```
**Location:** `src/AdvisoryAI/StellaOps.AdvisoryAI/Chat/Integration/AdvisoryAiPromptContextEnricher.cs`
## Object Link Format
OpsMemory uses structured object links for cross-referencing:
| Type | Format | Example |
|------|--------|---------|
| Decision | `[ops-mem:dec-{id}]` | `[ops-mem:dec-abc12345]` |
| Known Issue | `[ops-mem:issue-{id}]` | `[ops-mem:issue-xyz98765]` |
| Tactic | `[ops-mem:tactic-{id}]` | `[ops-mem:tactic-respond-001]` |
| Playbook | `[ops-mem:playbook-{id}]` | `[ops-mem:playbook-log4j-response]` |
### Link Resolution
The `OpsMemoryLinkResolver` resolves object links to display text and URLs:
```csharp
public interface IObjectLinkResolver
{
/// <summary>
/// Resolves an object link to display information.
/// </summary>
Task<ObjectLinkResolution?> ResolveAsync(
string objectLink,
CancellationToken ct = default);
}
```
**Example Resolution:**
```
Input: [ops-mem:dec-abc12345]

## Known Issues and Tactics
### Known Issues
Document common false positives or expected behaviors:
```csharp
public interface IKnownIssueStore
{
Task<KnownIssue?> GetByIdAsync(string id, CancellationToken ct);
Task<IReadOnlyList<KnownIssue>> SearchAsync(
KnownIssueSearchRequest request, CancellationToken ct);
}
```
**Example Known Issue:**
```json
{
"id": "issue-log4j-test-code",
"title": "Log4j in test dependencies",
"description": "Log4j detected in test-scope dependencies is not exploitable in production",
"applies_to": {
"cve_pattern": "CVE-2021-44228",
"scope": "test"
},
"recommended_action": "accept_risk",
"status": "active"
}
```
### Response Tactics
Pre-defined response strategies for common situations:
```csharp
public interface ITacticStore
{
Task<Tactic?> GetByIdAsync(string id, CancellationToken ct);
Task<IReadOnlyList<Tactic>> GetMatchingTacticsAsync(
TacticMatchRequest request, CancellationToken ct);
}
```
**Example Tactic:**
```json
{
"id": "tactic-quarantine-critical",
"name": "Quarantine Critical Vulnerabilities",
"trigger": {
"severity": ["CRITICAL"],
"reachability": ["REACHABLE", "UNKNOWN"]
},
"steps": [
"Block deployment to production",
"Notify security team",
"Schedule remediation within 24h"
],
"automation": {
"action": "quarantine",
"notify_channel": "#security-alerts"
}
}
```
## Integration Points
### AdvisoryAI Integration
Register OpsMemory integration during startup:
```csharp
services.AddAdvisoryAIOpsMemoryIntegration(options =>
{
options.Enabled = true;
options.MaxSuggestions = 3;
options.IncludeKnownIssues = true;
options.IncludeTactics = true;
});
```
### Chat Flow Integration
The integration hooks into the chat pipeline:
1. **Pre-Prompt**: `AdvisoryAiPromptContextEnricher` adds OpsMemory context
2. **Response**: AI references past decisions with object links
3. **Post-Action**: `OpsMemoryChatProvider.RecordDecisionAsync` captures the decision
## Best Practices
### Tuning Similarity Threshold
- **0.3-0.5**: Broader matches, may include less relevant decisions
- **0.5-0.7**: Balanced - recommended starting point
- **0.7+**: Strict matching, only very similar situations
### Recording Quality Decisions
For decisions to be useful for future suggestions:
1. **Include Context**: CVE ID, severity, package information
2. **Clear Rationale**: Why this action was chosen
3. **Track Outcomes**: Update with SUCCESS/FAILURE after implementation
### Managing Known Issues
- Review quarterly for relevance
- Archive issues for CVEs that are fully remediated
- Keep issue descriptions actionable
## Testing
### Unit Tests
Located in `src/AdvisoryAI/__Tests/StellaOps.AdvisoryAI.Tests/Chat/Integration/`:
- `OpsMemoryChatProviderTests.cs` - Provider functionality
- `AdvisoryAiPromptContextEnricherTests.cs` - Prompt enrichment
### Integration Tests
Located in `src/OpsMemory/__Tests/StellaOps.OpsMemory.Tests/Integration/`:
- `OpsMemoryChatProviderIntegrationTests.cs` - Full flow with PostgreSQL
