# VEX Proof Object Schema Reference
Version: 1.0 (stellaops.vex-proof.v1)
Last Updated: 2026-01-03
## Overview
VEX Proof Objects provide a cryptographically verifiable audit trail of how VEX consensus verdicts are computed. Every VEX resolution in StellaOps produces a proof object that documents the inputs, merge process, and decision rationale.
## JSON Schema
```json

"$schema": "http://json-schema.org/draft-07/schema#",
"title": "VEX Proof Object",
"type": "object",

## Digest Computation
The proof digest is computed using RFC 8785 canonical JSON serialization:
1. Serialize proof object to canonical JSON (sorted keys, minimal escaping)
2. Compute SHA-256 hash of canonical JSON bytes
3. Encode as hexadecimal
```json
{
"digest": {
"algorithm": "sha256",
"value": "a1b2c3d4..."
}
}
```

# SPRINT_20260102_001_BE_binary_delta_signatures.md
## Sprint Overview
| Field | Value |
|-------|-------|
| **Sprint ID** | SPRINT_20260102_001_BE |
| **Title** | Binary Delta Signatures for Patch Detection |
| **Working Directory** | `src/BinaryIndex/` |
| **Duration** | 4-6 weeks |
| **Dependencies** | None (foundational sprint) |
| **Advisory Source** | `docs/product-advisories/30-Dec-2025 - Binary Diff Signatures for Patch Detection.md` |
## Problem Statement
Vulnerability scanners today rely on version string comparison to determine if a package is vulnerable. But Linux distributions (RHEL, Debian, Ubuntu, SUSE, Alpine) routinely **backport** security fixes into older versions without bumping the upstream version number.
**Example:** OpenSSL 1.0.1e on RHEL 6 has Heartbleed patched, but upstream says `1.0.1e < 1.0.1g` (the fix version), so scanners flag it as vulnerable. This is **wrong**.
**Solution:** Examine the compiled binary itself. Hash the normalized code of affected functions. Compare against known "patched" and "vulnerable" signatures. This provides **cryptographic proof** the fix is present.
## Technical Design
### Disassembly Engine Selection
**Chosen: B2R2** (fully managed .NET, MIT license)
Rationale:
- **Purely managed (.NET)** - no P/Invoke, runs anywhere .NET runs
- **Multi-format** - ELF, PE, Mach-O (covers Linux, Windows, macOS)
- **Multi-ISA** - x86-64, ARM64 (covers server + Apple Silicon + ARM servers)
- **MIT license** - compatible with AGPL-3.0
- **Lifting capability** - can convert to IR for semantic normalization
- **Performance** - Second fastest after Iced in benchmarks
NuGet: `B2R2.FrontEnd.API` (targets net9.0, compatible with net10.0)
### Architecture

# Sprint Completion Summary - 2026-01-03
## SPRINT_20260103_001_FE - Filter Presets & Patch Map Explorer
**Status:** ✅ COMPLETE (All 11 tasks)
### Overview
Implemented two UX polish features for the vulnerability explorer:
1. **Filter Preset Pills** - Always-visible filter chips with URL synchronization for shareable filter states
2. **Patch Map Explorer** - Interactive heatmap showing vendor backport coverage across fleet
### Key Deliverables
#### Filter Presets (4 tasks)
- Extended `TriageFilters` with noise-gating fields (runtimeExecuted, environment, backportProved, semverMismatch)
- Created 7 standard presets: actionable, prod-runtime, backport-verified, critical-only, needs-review, vex-applied, all-findings
- `FilterUrlSyncService` for bidirectional URL synchronization
- `FilterPresetPillsComponent` with horizontal scrolling and copy URL
#### Patch Coverage Backend (3 tasks)
- Added 3 interface methods to `IDeltaSignatureRepository`
- Implemented PostgreSQL aggregation queries with CTEs
- Created `PatchCoverageController` with 3 REST endpoints:
- `GET /api/v1/stats/patch-coverage` - Aggregated coverage by CVE
- `GET /api/v1/stats/patch-coverage/{cveId}/details` - Function-level breakdown
- `GET /api/v1/stats/patch-coverage/{cveId}/matches` - Paginated affected images
#### Patch Map Frontend (4 tasks)
- Created `patch-coverage.models.ts` and `patch-coverage.client.ts`
- Created `PatchMapComponent` with heatmap, details, and matches views
- Added route `/analyze/patch-map` and navigation entry
- Linked from `binary-evidence-panel` header
### Files Created
| Location | Files |
|----------|-------|
| Frontend | `filter-preset.models.ts`, `filter-preset-pills.component.ts`, `filter-url-sync.service.ts`, `patch-coverage.models.ts`, `patch-coverage.client.ts`, `patch-map.component.ts` |
| Backend | `PatchCoverageController.cs` |
### Files Modified
| File | Change |
|------|--------|
| `evidence-subgraph.models.ts` | Added noise-gating fields |
| `app.routes.ts` | Added patch-map route |
| `navigation.config.ts` | Added Patch Map nav entry |
| `binary-evidence-panel.component.ts` | Added Patch Map link |
| `IDeltaSignatureRepository.cs` | Added 3 methods + 6 DTOs |
| `DeltaSignatureRepository.cs` | Implemented aggregation queries |
| `BinaryIndex.WebService.csproj` | Added Persistence project reference |
### Decisions
- CSS Grid for heatmap (accessibility compliance)
- Severity-based color coding (critical=red, high=orange, medium=yellow, low=blue, safe=green)
### Build Status
- Backend: ✅ Builds successfully (0 errors)
- Frontend: ⚠️ Pre-existing errors in other components (not sprint-related)

# Sprint 20260103_001_FE_preset_pills_patch_map - Filter Presets & Patch Map Explorer
## Topic & Scope
- Implement two UX polish features identified from product advisory feedback:
1. **Filter Preset Pills**: Always-visible filter chips above triage results with URL synchronization for shareable filter states
2. **Patch Map Explorer**: Interactive heatmap showing vendor backport coverage across fleet with drill-down to function-level and affected images
- **Working directory:** `src/Web/StellaOps.Web` (Frontend), `src/BinaryIndex` (Backend)
## Dependencies & Concurrency
- Extends existing `TriageFilters` model in vuln-explorer feature
- Requires delta signature data in BinaryIndex for patch coverage queries
- Can run independently of other sprints
## Documentation Prerequisites
- `docs/modules/binary-index/architecture.md`
- `docs/modules/vuln-explorer/architecture.md`

# VexLens Testing Strategy
## Overview
This document describes the testing strategy for VexLens module, covering determinism verification, regression testing, and golden corpus validation.
## Test Categories
### 1. Unit Tests (`Category=Unit`)
Standard unit tests for individual components:
- **Location:** `src/VexLens/StellaOps.VexLens/__Tests/StellaOps.VexLens.Tests/`
- **Coverage:** Models, builders, serializers, individual consensus components
- **Run frequency:** Every PR, every commit
### 2. Determinism Tests (`Category=Determinism`)
Tests that verify VexLens produces identical outputs for identical inputs:
- **Location:** `src/VexLens/StellaOps.VexLens/__Tests/StellaOps.VexLens.Tests/Determinism/`
- **Key tests:**
- `VexProofShuffleDeterminismTests` - Verifies statement order doesn't affect consensus
- `VexLensPipelineDeterminismTests` - E2E pipeline structural determinism
- **Run frequency:** Nightly regression suite
- **Requirements:** Fixed `TimeProvider` injection for reproducible timestamps
#### Known Limitations
The `VexProofBuilder.GenerateProofId()` method currently uses `Guid.NewGuid()` which introduces non-determinism in the ProofId (and consequently the Digest). This is tracked as risk R-003 and violates AGENTS.md Rule 8.2 (Inject TimeProvider / ID generators). Until `IGuidGenerator` injection is added, determinism tests validate structural determinism rather than byte-identical outputs.
### 3. Regression Tests (`Category=Regression`)
Tests that validate known scenarios produce expected verdicts:
- **Location:** `src/VexLens/StellaOps.VexLens/__Tests/StellaOps.VexLens.Tests/Regression/`
- **Key tests:**
- Fixed package verdict validation
- Not_affected with justification
- Conflict resolution via lattice precedence
- Backport scenario handling
- Under_investigation status preservation
- Signature verification confidence bonus
- Same-issuer temporal precedence
- **Run frequency:** Nightly regression suite
### 4. Golden Corpus Tests (`Category=Golden`)
Tests using curated real-world backport scenarios:
- **Location:** `src/VexLens/StellaOps.VexLens/__Tests/StellaOps.VexLens.Tests/GoldenCorpus/`
- **Data location:** `src/__Tests/__Datasets/GoldenBackports/`
- **Coverage:** 20 backport cases across 8 distributions (Debian, Ubuntu, RHEL, SUSE, CentOS, Alpine, Fedora, Rocky/Alma, Amazon Linux, Oracle Linux)
- **Run frequency:** Nightly regression suite
## Test Infrastructure
### Golden Corpus Structure
```
src/__Tests/__Datasets/GoldenBackports/
├── index.json # Corpus index with case metadata
├── CVE-YYYY-XXXXX-distro-package/
│ └── case.json # Individual test case
└── ...
```
### Case Schema
```json
{
"id": "case identifier",
"cve": "CVE-YYYY-XXXXX",
"distro": {
"name": "debian|rhel|...",
"version": "7|8|...",
"family": "debian|rpm|..."
},
"package": {
"name": "package-name",
"binary": "binary-name",
"vulnerableEvr": "vulnerable EVR",
"patchedEvr": "patched EVR"
},
"upstream": {
"vulnerableRange": "SemVer constraint",
"fixedVersion": "upstream fix version"
},
"expectedVerdict": {
"status": "fixed|not_affected|affected",
"reason": "backport_detected|...",
"upstreamWouldSay": "affected|..."
},
"evidence": {
"advisoryUrl": "URL to advisory",
"patchCommit": "optional commit hash",
"notes": "explanation"
}
}
```
### Test Runner Components
1. **GoldenCorpusLoader** - Loads and filters corpus cases
2. **GoldenCorpusTestRunner** - Executes evaluator against corpus
3. **GoldenCorpusTests** - xUnit test class for corpus validation
## CI Integration
### Nightly Regression (`.gitea/workflows/nightly-regression.yml`)
Test categories run nightly:
- Unit
- Architecture
- Contract
- Integration
- Security
- Golden
- **Determinism**
- **Regression**
### PR Gating
Quick tests run on every PR:
- Unit tests only
- Build determinism check
## Test Best Practices
### 1. Use FakeTimeProvider
Always inject `Microsoft.Extensions.Time.Testing.FakeTimeProvider` to ensure deterministic timestamps:
```csharp
private readonly FakeTimeProvider _timeProvider;
private readonly DateTimeOffset _fixedTime = new(2026, 1, 3, 12, 0, 0, TimeSpan.Zero);
public MyTests()
{
_timeProvider = new FakeTimeProvider(_fixedTime);
}
```
### 2. Set Confidence Explicitly
The `VexProofBuilder` calculates confidence from explicit weight values. For predictable test assertions, set all confidence-affecting properties:
```csharp
builder
.WithWeightSpread(0.95m)
.WithConditionCoverage(1.0m)
.WithSignatureBonus(0.10m)
.WithFreshnessBonus(0.05m);
```
### 3. Set Justification with Status
When testing `not_affected` status, pass justification to `WithFinalStatus`:
```csharp
.WithFinalStatus(VexStatus.NotAffected, VexJustification.VulnerableCodeNotPresent)
```
### 4. Use Correct Types
The `AddStatement` method requires proper types:
- `VexProofIssuer` - Not a string
- `VexProofWeight` with `VexProofWeightFactors` - Not a decimal
```csharp
builder.AddStatement(
id: "stmt-001",
source: "vendor-csaf",
issuer: new VexProofIssuer("Vendor", IssuerCategory.Vendor, TrustTier.Authoritative),
status: VexStatus.Fixed,
justification: null,
weight: new VexProofWeight(0.95m, new VexProofWeightFactors(0.95m, 1.0m, 0.9m, 1.0m, 0.8m)),
timestamp: _fixedTime,
signatureVerified: true);
```
### 5. IssuerCategory and TrustTier Values
Valid `IssuerCategory` values:
- `Unknown`, `Vendor`, `Distributor`, `Community`, `Internal`, `Aggregator`
Valid `TrustTier` values:
- `Authoritative`, `Trusted`, `Untrusted`, `Unknown`
## Future Improvements
1. **Inject IGuidGenerator** - Enable full digest determinism (R-003)
2. **Expand golden corpus** - Add more edge cases and distributions
3. **Property-based testing** - Use FsCheck for fuzzing VEX inputs
4. **Mutation testing** - Use Stryker.NET to validate test coverage quality

# AdvisoryAI Hosting Agent Charter
## Mission
- Provide hosting extensions and DI registration for AdvisoryAI services.
- Wire configuration, options validation, and infrastructure components.
## Responsibilities
- Maintain `ServiceCollectionExtensions` for clean DI registration.
- Keep options classes (`AdvisoryAiServiceOptions`, `AdvisoryAiGuardrailOptions`) well-documented and validated.
- Ensure file-system-based implementations (queue, cache, output store) remain deterministic and offline-safe.
- Coordinate with guardrail phrase loading and metric wiring.
## Required Reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/advisory-ai/architecture.md
- src/AdvisoryAI/AGENTS.md (parent module charter)
- docs/policy/assistant-parameters.md (guardrail and ops knobs)
## Working Directory & Scope
- Primary: src/AdvisoryAI/StellaOps.AdvisoryAI.Hosting/
- Dependencies: StellaOps.AdvisoryAI core library for contracts and abstractions.
- Shared libraries allowed only when referenced by this project.
## Key Components
- `ServiceCollectionExtensions` — DI registration entry point for WebService and Worker hosts.
- `AdvisoryAiServiceOptions` — main configuration container with nested queue/storage/inference/guardrail options.
- `AdvisoryAiServiceOptionsValidator` — startup validation ensuring required config is present.
- `FileSystemAdvisoryTaskQueue` — file-based task queue for offline-capable environments.
- `FileSystemAdvisoryPlanCache` — file-based plan caching with hash keys.
- `FileSystemAdvisoryOutputStore` — content-addressed output storage.
- `GuardrailPhraseLoader` — loads guardrail phrases from configuration or files.
- `AdvisoryAiMetrics` — meter and counter definitions.
## Testing Expectations
- Unit tests in `__Tests/StellaOps.AdvisoryAI.Tests` cover hosting registration paths.
- Test options validation for missing/invalid config scenarios.
- Verify file-system implementations with deterministic (seeded) data; no wall-clock timing.
- Integration tests should use in-memory or temp directories to avoid flakiness.
## Working Agreement
- Determinism: stable ordering, content-addressed caches, UTC ISO-8601 timestamps.
- Offline-friendly: no hardcoded external endpoints; respect BYO trust roots.
- Observability: structured logs with event ids; expose counters via `AdvisoryAiMetrics`.
- Configuration: prefer `IOptions<T>` with data annotations; validate on startup.
- Update sprint status in docs/implplan/SPRINT_*.md when starting/completing work.
- Mirror decisions in sprint Decisions & Risks section.

# AdvisoryAI Worker Agent Charter
## Mission
- Execute queued advisory tasks asynchronously as a background service.
- Process advisory plans, orchestrate pipeline execution, and record metrics.
## Responsibilities
- Maintain `AdvisoryTaskWorker` background service for queue consumption.
- Coordinate plan creation/caching and pipeline execution.
- Track metrics for plan creation, execution latency, and cache hit rates.
- Handle graceful shutdown and task cancellation.
## Required Reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/advisory-ai/architecture.md
- docs/modules/advisory-ai/orchestration-pipeline.md
- src/AdvisoryAI/AGENTS.md (parent module charter)
- docs/policy/assistant-parameters.md (guardrail and ops knobs)
## Working Directory & Scope
- Primary: src/AdvisoryAI/StellaOps.AdvisoryAI.Worker/
- Dependencies: StellaOps.AdvisoryAI, StellaOps.AdvisoryAI.Hosting
- Coordinates with: WebService (queues tasks), core orchestrator (executes plans)
## Key Components
- `Program.cs` — Host builder setup with AdvisoryAI core and hosted service registration.
- `Services/AdvisoryTaskWorker.cs` — BackgroundService that:
- Dequeues tasks from `IAdvisoryTaskQueue`
- Checks `IAdvisoryPlanCache` for existing plans
- Creates new plans via `IAdvisoryPipelineOrchestrator`
- Executes plans via `IAdvisoryPipelineExecutor`
- Records metrics via `AdvisoryPipelineMetrics`
- Uses injected `TimeProvider` for deterministic timing
## Processing Flow
1. Dequeue message from `IAdvisoryTaskQueue`
2. Check plan cache by `PlanCacheKey` (unless `ForceRefresh`)
3. If cache miss, create plan via orchestrator and cache it
4. Execute plan via executor
5. Record metrics and log completion
6. Loop until cancellation
## Testing Expectations
- Unit tests in `__Tests/StellaOps.AdvisoryAI.Tests` cover worker logic.
- Test with mocked queue, cache, orchestrator, and executor.
- Verify cancellation handling and graceful shutdown.
- Test cache hit/miss scenarios and ForceRefresh behavior.
- Use FakeTimeProvider for deterministic timing tests.
## Working Agreement
- Determinism: use injected TimeProvider, stable plan caching keys, ordered execution.
- Offline-friendly: worker must handle unavailable inference gracefully.
- Observability: structured logs with activity tracing, expose pipeline metrics.
- Configuration: bind from appsettings.json and environment variables (ADVISORYAI__ prefix).
- Queue/cache: respect bounded capacities and TTLs configured via options.
- Update sprint status in docs/implplan/SPRINT_*.md when starting/completing work.
- Mirror decisions in sprint Decisions & Risks section.

- Enable creation and consumption of offline knowledge snapshot bundles.
## Responsibilities
- Maintain bundle format schemas and models (`BundleManifest`, `KnowledgeSnapshotManifest`).
- Implement bundle building (`BundleBuilder`), loading (`BundleLoader`), and reading/writing (`SnapshotBundleReader/Writer`).
- Provide manifest signing (`SnapshotManifestSigner`) with DSSE/TUF verification support.
- Implement import targets for Concelier advisories, Excititor VEX, and policy registry.
- Ensure bundle operations are deterministic and verifiable.
## Required Reading
- docs/README.md
- docs/07_HIGH_LEVEL_ARCHITECTURE.md
- docs/modules/platform/architecture-overview.md
- docs/modules/airgap/architecture.md
- src/AirGap/AGENTS.md (parent module charter)
- docs/24_OFFLINE_KIT.md
## Working Directory & Scope
- Primary: src/AirGap/__Libraries/StellaOps.AirGap.Bundle/
- Dependencies: StellaOps.AirGap.Persistence, StellaOps.Cryptography
- Coordinates with: AirGap.Importer (consumes bundles), AirGap.Controller (seal state)
## Key Components
### Models/
- `BundleManifest.cs` — Top-level bundle metadata and entry list
- `KnowledgeSnapshotManifest.cs` — Snapshot-specific manifest with digest references
### Services/
- `BundleBuilder.cs` — Creates bundles from source data with manifest generation
- `BundleLoader.cs` — Loads and validates existing bundles
- `SnapshotBundleReader.cs` — Streaming reader for bundle contents
- `SnapshotBundleWriter.cs` — Streaming writer for bundle creation
- `SnapshotManifestSigner.cs` — DSSE signing of manifests
- `TimeAnchorService.cs` — Time anchor integration for staleness tracking
- `KnowledgeSnapshotImporter.cs` — Orchestrates snapshot import
### Import Targets/
- `ConcelierAdvisoryImportTarget.cs` — Advisory data import
- `ExcititorVexImportTarget.cs` — VEX statement import
- `PolicyRegistryImportTarget.cs` — Policy bundle import
### Extractors/
- Archive extraction utilities for bundle contents
### Schemas/
- JSON schema definitions for bundle formats
### Validation/
- Bundle format and content validators
### Serialization/
- Bundle serialization/deserialization helpers
## Testing Expectations
- Unit tests in `__Libraries/__Tests/StellaOps.AirGap.Bundle.Tests/`
- Test bundle round-trips (build -> serialize -> load -> verify)
- Verify manifest signing and verification with test keys
- Test import targets with fixture data
- Ensure deterministic ordering in manifests and archives
- Test extraction with malformed/tampered data for security
## Working Agreement
- Determinism: stable manifest ordering, content-addressed digests, reproducible archives.
- Offline-friendly: no network calls; all data comes from local bundle files.
- Security: mandatory signature verification; reject tampered bundles.
- Schema stability: bundle format changes require versioning and migration support.
- Observability: structured logs for bundle operations, import metrics.
- Update sprint status in docs/implplan/SPRINT_*.md when starting/completing work.
- Mirror decisions in sprint Decisions & Risks section.
