Add tests for SBOM generation determinism across multiple formats
- Created `StellaOps.TestKit.Tests` project for unit tests related to determinism. - Implemented `DeterminismManifestTests` to validate deterministic output for canonical bytes and strings, file read/write operations, and error handling for invalid schema versions. - Added `SbomDeterminismTests` to ensure identical inputs produce consistent SBOMs across SPDX 3.0.1 and CycloneDX 1.6/1.7 formats, including parallel execution tests. - Updated project references in `StellaOps.Integration.Determinism` to include the new determinism testing library.

# TestKit Unblocking Analysis — ULTRA-DEEP DIVE
|
||||
|
||||
**Date:** 2025-12-23
|
||||
**Status:** CRITICAL PATH BLOCKER - ACTIVE RESOLUTION
|
||||
**Analyst:** Implementation Team
|
||||
**Scope:** Complete dependency resolution, build validation, and downstream unblocking strategy
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
Sprint 5100.0007.0002 (TestKit Foundations) is **COMPLETE** in implementation (13/13 tasks) but **BLOCKED** at build validation due to:
|
||||
1. **Namespace collisions** (old vs. new implementation files)
|
||||
2. **API mismatches** (CanonicalJson API changed)
|
||||
3. **Missing package references** (Npgsql, OpenTelemetry.Exporter.InMemory)
|
||||
|
||||
**Impact:** TestKit blocks ALL 15 module/infrastructure test sprints (Weeks 7-14), representing ~280 downstream tasks.
|
||||
|
||||
**Resolution ETA:** 2-4 hours (same-day fix achievable)
|
||||
|
||||
---
|
||||
|
||||
## Part 1: Root Cause Analysis
|
||||
|
||||
### 1.1 Namespace Collision (RESOLVED ✓)
|
||||
|
||||
**Problem:**
|
||||
Two conflicting file structures from different implementation sessions:
|
||||
- **OLD:** `Random/DeterministicRandom.cs`, `Time/DeterministicClock.cs`, `Json/CanonicalJsonAssert.cs`, etc.
|
||||
- **NEW:** `Deterministic/DeterministicTime.cs`, `Deterministic/DeterministicRandom.cs`, `Assertions/CanonicalJsonAssert.cs`
|
||||
|
||||
**Symptoms:**
|
||||
```
|
||||
error CS0118: 'Random' is a namespace but is used like a type
|
||||
error CS0509: cannot derive from sealed type 'LaneAttribute'
|
||||
```
|
||||
|
||||
**Root Cause:**
|
||||
`namespace StellaOps.TestKit.Random` conflicted with `System.Random`.
|
||||
|
||||
**Resolution Applied:**
|
||||
1. Deleted old directories: `Random/`, `Time/`, `Json/`, `Telemetry/`, `Snapshots/`, `Determinism/`, `Traits/`
|
||||
2. Updated `Deterministic/DeterministicRandom.cs` to use `System.Random` explicitly
|
||||
3. Kept simpler `TestCategories.cs` constants instead of complex attribute inheritance
|
||||
|
||||
**Status:** ✓ RESOLVED
|
||||
|
||||
---
|
||||
|
||||
### 1.2 CanonicalJson API Mismatch (90% RESOLVED)
|
||||
|
||||
**Problem:**
|
||||
Implementation assumed API: `CanonicalJson.SerializeToUtf8Bytes()`, `CanonicalJson.Serialize()`
|
||||
Actual API: `CanonJson.Canonicalize()`, `CanonJson.Hash()`
|
||||
|
||||
**File:** `src/__Libraries/StellaOps.Canonical.Json/CanonJson.cs`
|
||||
**Actual API Surface:**
|
||||
```csharp
|
||||
public static class CanonJson
|
||||
{
|
||||
byte[] Canonicalize<T>(T obj)
|
||||
byte[] Canonicalize<T>(T obj, JsonSerializerOptions options)
|
||||
byte[] CanonicalizeParsedJson(ReadOnlySpan<byte> jsonBytes)
|
||||
string Sha256Hex(ReadOnlySpan<byte> bytes)
|
||||
string Sha256Prefixed(ReadOnlySpan<byte> bytes)
|
||||
string Hash<T>(T obj)
|
||||
string HashPrefixed<T>(T obj)
|
||||
}
|
||||
```
|
||||
|
||||
**Resolution Applied:**
|
||||
Updated `Assertions/CanonicalJsonAssert.cs`:
|
||||
```csharp
|
||||
// OLD: CanonicalJson.SerializeToUtf8Bytes(value)
|
||||
// NEW: Canonical.Json.CanonJson.Canonicalize(value)
|
||||
|
||||
// OLD: CanonicalJson.Serialize(value)
|
||||
// NEW: Encoding.UTF8.GetString(CanonJson.Canonicalize(value))
|
||||
|
||||
// OLD: Custom SHA-256 computation
|
||||
// NEW: CanonJson.Hash(value)
|
||||
```
|
||||
|
||||
**Status:** ✓ RESOLVED (7/7 references updated)
|
||||
|
||||
---
|
||||
|
||||
### 1.3 Missing NuGet Dependencies (IN PROGRESS)
|
||||
|
||||
**Problem:**
|
||||
Three files reference packages not listed in `.csproj`:
|
||||
|
||||
#### A. PostgresFixture.cs
|
||||
**Missing:** `Npgsql` package
|
||||
**Error:**
|
||||
```
|
||||
error CS0246: The type or namespace name 'Npgsql' could not be found
|
||||
```
|
||||
|
||||
**Lines 59, 62, 89:**
|
||||
```csharp
|
||||
using Npgsql;
|
||||
// ...
|
||||
public async Task RunMigrationsAsync(NpgsqlConnection connection)
|
||||
```
|
||||
|
||||
**Resolution Required:**
|
||||
```xml
|
||||
<PackageReference Include="Npgsql" Version="8.0.5" />
|
||||
```
|
||||
|
||||
#### B. OtelCapture.cs (Old implementation - DELETED)
|
||||
**Missing:** `OpenTelemetry.Exporter.InMemory`
|
||||
**File:** `Telemetry/OTelCapture.cs` (OLD - should be deleted)
|
||||
|
||||
**Actual File:** `Observability/OtelCapture.cs` (NEW - uses Activity API directly, no package needed)
|
||||
|
||||
**Status:** Directory deletion in progress (old `Telemetry/` folder)
|
||||
|
||||
#### C. HttpFixtureServer.cs
|
||||
**Missing:** `Microsoft.AspNetCore.Mvc.Testing`
|
||||
**Already Added:** Line 18 of StellaOps.TestKit.csproj ✓
|
||||
|
||||
**Status:** ✓ RESOLVED

|
||||
```
|
||||
|
||||
**Blocked Work:**
|
||||
- **Epic B (Determinism Gate):** 12 tasks, 3 engineers, Week 2-3
|
||||
- **Epic C (Storage Harness):** 14 tasks, 2 engineers, Week 2-4
|
||||
- **Module Tests:** 15 sprints × ~18 tasks = 270 tasks, Weeks 7-10
|
||||
- **Total Downstream Impact:** ~296 tasks, 22-26 engineers
|
||||
|
||||
**Financial Impact (Preliminary):**
|
||||
- 1 day delay = ~$45,000 (26 engineers × $175/hr × 10 hrs)
|
||||
- TestKit build fix ETA: 2-4 hours → Same-day resolution achievable
|
||||
|
||||
---
|
||||
|
||||
### 2.2 Parallelization Opportunities
|
||||
|
||||
**Once TestKit Builds:**
|
||||
|
||||
#### Week 2 (Immediate Parallel Start):
|
||||
- Epic B: Determinism Gate (3 engineers, Platform Guild)
|
||||
- Epic C: Storage Harness (2 engineers, Infrastructure Guild)
|
||||
- Epic D: Connector Fixtures (2 engineers, QA Guild)
|
||||
- Total: 7 engineers working in parallel
|
||||
|
||||
#### Week 7-10 (Max Parallelization):
|
||||
After Epics B-C complete, launch ALL 15 module test sprints in parallel:
|
||||
- Scanner (25 tasks, 3 engineers)
|
||||
- Concelier (22 tasks, 3 engineers)
|
||||
- Excititor (21 tasks, 2 engineers)
|
||||
- Policy, Authority, Signer, Attestor, Scheduler, Notify (14-18 tasks each, 1-2 engineers)
|
||||
- CLI, UI (13 tasks each, 2 engineers)
|
||||
- EvidenceLocker, Graph, Router, AirGap (14-17 tasks, 2 engineers each)
|
||||
|
||||
**Total Peak Capacity:** 26 engineers (Weeks 7-10)
|
||||
|
||||
---
|
||||
|
||||
## Part 3: Immediate Action Plan
|
||||
|
||||
### 3.1 Build Fix Sequence (Next 2 Hours)
|
||||
|
||||
#### TASK 1: Add Missing NuGet Packages (5 min)
|
||||
**File:** `src/__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj`
|
||||
|
||||
**Add:**
|
||||
```xml
|
||||
<ItemGroup>
|
||||
<PackageReference Include="Npgsql" Version="8.0.5" />
|
||||
</ItemGroup>
|
||||
```
|
||||
|
||||
**Validation:**
|
||||
```bash
|
||||
dotnet restore src/__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### TASK 2: Fix OtelCapture xUnit Warning (10 min)
|
||||
**File:** `src/__Libraries/StellaOps.TestKit/Observability/OtelCapture.cs:115`
|
||||
|
||||
**Error:**
|
||||
```
|
||||
warning xUnit2002: Do not use Assert.NotNull() on value type 'KeyValuePair<string, string?>'
|
||||
```
|
||||
|
||||
**Fix:**
|
||||
```csharp
|
||||
// OLD (line 115):
|
||||
Assert.NotNull(tag);
|
||||
|
||||
// NEW:
|
||||
// Remove Assert.NotNull for value types (KeyValuePair is struct)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### TASK 3: Build Validation (5 min)
|
||||
```bash
|
||||
dotnet build src/__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj
|
||||
```
|
||||
|
||||
**Expected Output:**
|
||||
```
|
||||
Build succeeded.
|
||||
0 Warning(s)
|
||||
0 Error(s)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
#### TASK 4: Pilot Test Validation (15 min)
|
||||
```bash
|
||||
dotnet test src/Scanner/__Tests/StellaOps.Scanner.Core.Tests/ --filter "FullyQualifiedName~TestKitExamples"
|
||||
```
|
||||
|
||||
**Expected:** 5 passing tests
|
||||
**Tests:**
|
||||
- `DeterministicTime_Example`
|
||||
- `DeterministicRandom_Example`
|
||||
- `CanonicalJsonAssert_Determinism_Example`
|
||||
- `SnapshotAssert_Example`
|
||||
- `CanonicalJsonAssert_PropertyCheck_Example`
|
||||
|
||||
**Failure Scenarios:**
|
||||
- Snapshot missing → Run with `UPDATE_SNAPSHOTS=1`
|
||||
- PostgresFixture error → Ensure Docker running
|
||||
- Canonical hash mismatch → API still misaligned
|
||||

## Part 4: Rollout Strategy for 15 Module Sprints
|
||||
|
||||
### 4.1 TestKit Adoption Checklist
|
||||
|
||||
**For each module test sprint:**
|
||||
|
||||
#### Step 1: Add TestKit Reference
|
||||
```xml
|
||||
<ProjectReference Include="../../../__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj" />
|
||||
```
|
||||
|
||||
#### Step 2: Create Example Tests
|
||||
File: `<Module>.Tests/TestKitExamples.cs`
|
||||
```csharp
|
||||
using StellaOps.TestKit;
|
||||
using StellaOps.TestKit.Deterministic;
|
||||
using StellaOps.TestKit.Assertions;
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Unit)]
|
||||
public void DeterministicTime_Example() { ... }
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Snapshot)]
|
||||
public void SnapshotAssert_Example() { ... }
|
||||
```
|
||||
|
||||
#### Step 3: Validate Pilot Tests
|
||||
```bash
|
||||
dotnet test <Module>.Tests/ --filter "FullyQualifiedName~TestKitExamples"
|
||||
```
|
||||
|
||||
#### Step 4: Migrate Existing Tests (Optional)
|
||||
- Replace `DateTime.UtcNow` → `DeterministicTime.UtcNow`
|
||||
- Replace `Guid.NewGuid()` → `DeterministicRandom.NextGuid()`
|
||||
- Add `[Trait("Category", TestCategories.<Lane>)]` to all tests
|
||||

## Part 5: Risk Mitigation
|
||||
|
||||
### 5.1 High-Impact Risks
|
||||
|
||||
| Risk | Probability | Impact | Mitigation | Owner |
|
||||
|------|-------------|--------|------------|-------|
|
||||
| **TestKit build fails after fixes** | LOW (20%) | CRITICAL | Create rollback branch; validate each fix incrementally | Implementation Team |
|
||||
| **Pilot tests fail in Scanner.Core.Tests** | MEDIUM (40%) | HIGH | Run tests locally before committing; update snapshots with `UPDATE_SNAPSHOTS=1` | QA Guild |
|
||||
| **Npgsql version conflict** | LOW (15%) | MEDIUM | Pin to 8.0.5 (latest stable); check for conflicts with existing projects | Platform Guild |
|
||||
| **Epic B/C delayed by resource contention** | MEDIUM (30%) | HIGH | Reserve 3 senior engineers for Epic B; 2 for Epic C; block other work | Project Mgmt |
|
||||
| **Module sprints start before Epics B/C complete** | HIGH (60%) | MEDIUM | Allow module sprints to start with TestKit only; integrate determinism/storage later | QA Guild |
|
||||
| **.NET 10 compatibility issues** | LOW (10%) | MEDIUM | Testcontainers 3.10.0 supports .NET 8-10; validate locally | Platform Guild |
|
||||
| **Docker not available in CI** | MEDIUM (25%) | HIGH | Configure CI runners with Docker; add Docker health check to pipelines | CI Guild |
|
||||
| **Snapshot baseline conflicts (multiple engineers)** | HIGH (70%) | LOW | Use `UPDATE_SNAPSHOTS=1` only on designated "snapshot update" branches; review diffs in PR | QA Guild |
|
||||
|
||||
---
|
||||
|
||||
### 5.2 Contingency Plans
|
||||
|
||||
#### Scenario A: TestKit Build Still Fails
|
||||
**Trigger:** Build errors persist after Npgsql package added
|
||||
**Response:**
|
||||
1. Rollback to last known good state (pre-edit)
|
||||
2. Create minimal TestKit v0.9 with ONLY working components:
|
||||
- DeterministicTime
|
||||
- DeterministicRandom
|
||||
- TestCategories
|
||||
3. Defer CanonicalJsonAssert, PostgresFixture to v1.1
|
||||
4. Unblock Epic B with minimal TestKit
|
||||
|
||||
**Impact:** Epic C delayed 1 week (PostgresFixture critical)
|
||||
**Mitigation:** Platform Guild pairs with original Canonical.Json author
|
||||
|
||||
---
|
||||
|
||||
#### Scenario B: .NET 10 Package Incompatibilities
|
||||
**Trigger:** Testcontainers or OpenTelemetry packages fail on .NET 10
|
||||
**Response:**
|
||||
1. Downgrade TestKit to `net8.0` target (instead of `net10.0`)
|
||||
2. Validate on .NET 8 SDK
|
||||
3. File issues with Testcontainers/OpenTelemetry teams
|
||||
4. Upgrade to .NET 10 in TestKit v1.1 (after package updates)
|
||||
|
||||
**Impact:** Minimal (test projects can target .NET 8)
|
||||
|
||||
---
|
||||
|
||||
#### Scenario C: Epic B/C Miss Week 3 Deadline
|
||||
**Trigger:** Determinism/Storage harnesses not ready by 2026-02-05
|
||||
**Response:**
|
||||
1. Launch module sprints WITHOUT Epic B/C integration
|
||||
2. Module tests use TestKit primitives only
|
||||
3. Retrofit determinism/storage tests in Week 11-12 (after module sprints)
|
||||
|
||||
**Impact:** Determinism gate delayed 2 weeks; module sprints unaffected
|
||||

## Part 8: Long-Term Vision
|
||||
|
||||
### 8.1 TestKit v2 Roadmap (Q2 2026)
|
||||
|
||||
**Candidate Features:**
|
||||
- **Performance benchmarking**: BenchmarkDotNet integration
|
||||
- **Property-based testing**: Enhanced FsCheck generators for domain models
|
||||
- **Advanced fixtures**: ValkeyFixture improvements, S3 mock fixture
|
||||
- **Distributed tracing**: Multi-service OtelCapture for integration tests
|
||||
- **Snapshot diffing**: Visual diff tool for snapshot mismatches
|
||||
- **Test data builders**: Fluent builders for SBOM, VEX, Policy objects
|
||||
|
||||
**Prioritization Criteria:**
|
||||
- Guild votes (module teams request features)
|
||||
- Complexity reduction (eliminate test boilerplate)
|
||||
- Determinism enforcement (prevent flaky tests)
|
||||
|
||||
---
|
||||
|
||||
### 8.2 Testing Culture Transformation
|
||||
|
||||
**Current State:**
|
||||
- Ad-hoc test infrastructure per module
|
||||
- Flaky tests tolerated
|
||||
- Manual snapshot management
|
||||
- No determinism enforcement
|
||||
|
||||
**Target State (Post-Program):**
|
||||
- Shared TestKit across all modules
|
||||
- Zero flaky tests (determinism gate enforces)
|
||||
- Automated snapshot updates (UPDATE_SNAPSHOTS=1 in CI)
|
||||
- Determinism verification for all artifacts (SBOM, VEX, Policy, Evidence)
|
||||
|
||||
**Cultural Shifts:**
|
||||
- **Test-first mindset**: Write tests before implementation
|
||||
- **Snapshot discipline**: Review snapshot diffs in PRs
|
||||
- **Determinism first**: Reject non-reproducible outputs
|
||||
- **CI gate enforcement**: Tests must pass before merge

## Conclusion
|
||||
|
||||
TestKit unblocking is achievable within **2-4 hours** (same-day). The critical path forward:
|
||||
|
||||
1. **Fix build** (add Npgsql, fix xUnit warning)
|
||||
2. **Validate pilot tests** (Scanner.Core.Tests)
|
||||
3. **Kickoff Epic B/C** (Week 2)
|
||||
4. **Prepare module guilds** (TestKit adoption training)
|
||||
5. **Launch 15 module sprints** (Week 7, parallel execution)
|
||||
|
||||
**Success depends on:**
|
||||
- Immediate build validation (today)
|
||||
- Resource reservation for Epic B/C (Week 2)
|
||||
- Guild coordination for parallel rollout (Week 7)
|
||||
|
||||
**Risk is LOW**; mitigation strategies in place for all scenarios.
|
||||
|
||||
**ETA to Full Unblock:** 2026-02-05 (Epic B/C complete, module sprints ready to launch)

## Overview
|
||||
|
||||
The **OfflineVerificationCryptoProvider** is a cryptographic provider designed for offline and air-gapped environments. It wraps .NET BCL cryptography (`System.Security.Cryptography`) within the `ICryptoProvider` abstraction, enabling configuration-driven crypto while maintaining offline verification capabilities.
|
||||
The **OfflineVerificationCryptoProvider** is a cryptographic abstraction layer that wraps .NET BCL (`System.Security.Cryptography`) to enable **configuration-driven cryptography** in offline, air-gapped, and sovereignty-constrained environments.
|
||||
|
||||
This provider is particularly useful for:
|
||||
- **Air-gapped deployments** where hardware security modules (HSMs) are unavailable
|
||||
- **Offline bundle verification** in disconnected environments
|
||||
- **Development and testing** environments
|
||||
- **Fallback scenarios** when regional crypto providers are unavailable
|
||||
### Purpose
|
||||
|
||||
## When to Use This Provider
|
||||
- **Offline Operations**: Function without network access to external cryptographic services
|
||||
- **Deterministic Behavior**: Reproducible signatures and hashes for compliance auditing
|
||||
- **Zero External Dependencies**: No cloud KMS, HSMs, or online certificate authorities required
|
||||
- **Regional Neutrality**: NIST-approved algorithms without regional compliance constraints
|
||||
|
||||
### ✅ Recommended Use Cases
|
||||
### Key Features
|
||||
|
||||
1. **Air-Gapped Bundle Verification**
|
||||
- Verifying DSSE-signed evidence bundles in disconnected environments
|
||||
- Validating attestations without external connectivity
|
||||
- Offline policy verification
|
||||
- ECDSA (ES256/384/512) and RSA (RS256/384/512, PS256/384/512) signing/verification
|
||||
- SHA-2 family hashing (SHA-256/384/512)
|
||||
- Ephemeral verification for public-key-only scenarios (DSSE, JWT, JWS)
|
||||
- Configuration-driven plugin architecture with priority-based selection
|
||||
- Zero-cost abstraction over .NET BCL primitives
|
||||
|
||||
2. **Development & Testing**
|
||||
- Local development without HSM dependencies
|
||||
- CI/CD pipelines for automated testing
|
||||
- Integration test environments
|
||||
---
|
||||
|
||||
3. **Fallback Provider**
|
||||
- When regional providers (GOST, SM, eIDAS) are unavailable
|
||||
- Default offline verification path
|
||||
## Architecture
|
||||
|
||||
### ❌ NOT Recommended For
|
||||
### Component Hierarchy
|
||||
|
||||
1. **Production Signing Operations** - Use HSM-backed providers instead
|
||||
2. **Compliance-Critical Scenarios** - Use certified providers (FIPS, eIDAS, etc.)
|
||||
3. **High-Value Key Storage** - Use hardware-backed key storage

|
||||
|
||||
### Basic Usage
|
||||
## Deployment Scenarios
|
||||
|
||||
```csharp
|
||||
using StellaOps.Cryptography;
|
||||
using StellaOps.Cryptography.Plugin.OfflineVerification;
|
||||
### Scenario 1: Air-Gapped Container Scanning
|
||||
|
||||
// Create provider instance
|
||||
var provider = new OfflineVerificationCryptoProvider();
|
||||
**Environment**: Offline network segment, no internet access
|
||||
|
||||
// Check algorithm support
|
||||
bool supportsES256 = provider.Supports(CryptoCapability.Signing, "ES256");
|
||||
// Returns: true
|
||||
|
||||
// Get a hasher
|
||||
var hasher = provider.GetHasher("SHA-256");
|
||||
var hash = hasher.ComputeHash(dataBytes);
|
||||
|
||||
// Get a signer (requires key reference)
|
||||
var keyRef = new CryptoKeyReference("my-signing-key");
|
||||
var signer = provider.GetSigner("ES256", keyRef);
|
||||
var signature = await signer.SignAsync(dataBytes);
|
||||
```
|
||||
|
||||
### Ephemeral Verification (New in v1.0)
|
||||
|
||||
For verification-only scenarios where you have raw public key bytes (e.g., DSSE verification):
|
||||
|
||||
```csharp
|
||||
// Create ephemeral verifier from SubjectPublicKeyInfo bytes
|
||||
byte[] publicKeyBytes = LoadPublicKeyFromDsse();
|
||||
var verifier = provider.CreateEphemeralVerifier("ES256", publicKeyBytes);
|
||||
|
||||
// Verify signature (no private key required)
|
||||
var isValid = await verifier.VerifyAsync(dataBytes, signatureBytes);
|
||||
```
|
||||
|
||||
**When to use ephemeral verification:**
|
||||
- DSSE envelope verification with inline public keys
|
||||
- One-time verification operations
|
||||
- No need to persist keys in provider's key store
|
||||
|
||||
### Dependency Injection Setup
|
||||
|
||||
```csharp
|
||||
using Microsoft.Extensions.DependencyInjection;
|
||||
using StellaOps.Cryptography;
|
||||
using StellaOps.Cryptography.Plugin.OfflineVerification;
|
||||
|
||||
// Add to DI container
|
||||
services.AddSingleton<ICryptoProvider, OfflineVerificationCryptoProvider>();
|
||||
|
||||
// Or use with crypto provider registry
|
||||
services.AddSingleton<ICryptoProviderRegistry>(sp =>
|
||||
**Configuration**:
|
||||
```json
|
||||
{
|
||||
var registry = new CryptoProviderRegistry();
|
||||
registry.RegisterProvider(new OfflineVerificationCryptoProvider());
|
||||
return registry;
|
||||
});
|
||||
```
|
||||
|
||||
### Air-Gapped Bundle Verification Example
|
||||
|
||||
```csharp
|
||||
using StellaOps.Cryptography;
|
||||
using StellaOps.Cryptography.Plugin.OfflineVerification;
|
||||
using StellaOps.AirGap.Importer.Validation;
|
||||
|
||||
// Initialize provider
|
||||
var cryptoRegistry = new CryptoProviderRegistry([
|
||||
new OfflineVerificationCryptoProvider()
|
||||
]);
|
||||
|
||||
// Create DSSE verifier with crypto provider
|
||||
var dsseVerifier = new DsseVerifier(cryptoRegistry);
|
||||
|
||||
// Verify bundle signature
|
||||
var trustRoots = new TrustRootConfig
|
||||
{
|
||||
PublicKeys = new Dictionary<string, byte[]>
|
||||
{
|
||||
["airgap-signer"] = LoadPublicKeyBytes()
|
||||
},
|
||||
TrustedKeyFingerprints = new HashSet<string>
|
||||
{
|
||||
ComputeFingerprint(LoadPublicKeyBytes())
|
||||
}
|
||||
};
|
||||
|
||||
var result = dsseVerifier.Verify(dsseEnvelope, trustRoots);
|
||||
if (result.IsSuccess)
|
||||
{
|
||||
Console.WriteLine("Bundle signature verified successfully!");
|
||||
"cryptoProvider": "offline-verification",
|
||||
"algorithms": {
|
||||
"signing": "ES256",
|
||||
"hashing": "SHA-256"
|

||||
"sha256:f6e5d4c3b2a1...."
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Configuration
|
||||
**Trust Establishment**:
|
||||
1. Pre-distribute trust bundle via USB/DVD: `offline-kit.tar.gz`
|
||||
2. Bundle contains:
|
||||
- Public key fingerprints (`trust-anchors.json`)
|
||||
- Root CA certificates (if applicable)
|
||||
- Offline crypto provider plugin
|
||||
3. Operator verifies bundle signature using out-of-band channel
|
||||
|
||||

OfflineVerificationCryptoProvider
|
||||
```
|
||||
|
||||
The offline verification provider is typically enabled by default:
|
||||
### Scenario 2: Sovereign Cloud Deployment
|
||||
|
||||
**Environment**: National cloud with data residency requirements
|
||||
|
||||
**Configuration**:
|
||||
```json
|
||||
{
|
||||
"cryptoProvider": "offline-verification",
|
||||
"jurisdiction": "world",
|
||||
"compliance": ["NIST", "offline-airgap"],
|
||||
"keyRotation": {
|
||||
"enabled": true,
|
||||
"intervalDays": 90
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Key Considerations**:
|
||||
- Keys generated and stored within sovereign boundary
|
||||
- No external KMS dependencies
|
||||
- Audit trail for all cryptographic operations
|
||||
- Compliance with local data protection laws
|
||||
|
||||
### Scenario 3: CI/CD Pipeline with Reproducible Builds
|
||||
|
||||
**Environment**: Build server with deterministic signing
|
||||
|
||||
**Configuration**:
|
||||
```json
|
||||
{
|
||||
"cryptoProvider": "offline-verification",
|
||||
"deterministicSigning": true,
|
||||
"algorithms": {
|
||||
"signing": "ES256",
|
||||
"hashing": "SHA-256"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Workflow**:
|
||||
1. Build produces identical artifact hash
|
||||
2. Offline provider signs with deterministic ECDSA (RFC 6979)
|
||||
3. CI stores signature alongside artifact
|
||||
4. Downstream consumers verify signature before deployment

### ICryptoProvider.CreateEphemeralVerifier (New in v1.0)
|
||||
|
||||
**Signature**:
|
||||
```csharp
|
||||

|
||||
|
||||
**Returns**: `ICryptoSigner` instance with:
|
||||
- `VerifyAsync(data, signature)` - Returns `true` if signature valid
|
||||
- `SignAsync(data)` - Throws `NotSupportedException`
|
||||
- `KeyId` - Returns `"ephemeral"`
|
||||
- `AlgorithmId` - Returns the specified algorithm
|
||||
|
||||
**Throws**:
|
||||
- `NotSupportedException`: Algorithm not supported or public key format invalid
|
||||
- `CryptographicException`: Public key parsing failed
|
||||
|
||||
**Usage Example**:
|
||||
```csharp

|
||||
var trustRoots = LoadTrustRoots();
|
||||
|
||||
foreach (var signature in envelope.Signatures)
|
||||
{
|
||||
// Get public key from trust store
|
||||
if (!trustRoots.PublicKeys.TryGetValue(signature.KeyId, out var publicKeyBytes))
|
||||
continue;
|
||||
|
||||
// Verify fingerprint
|
||||
var fingerprint = ComputeFingerprint(publicKeyBytes);
|
||||
if (!trustRoots.TrustedFingerprints.Contains(fingerprint))
|

}
|

```
|
||||
|
||||
**Priority:** `45` - Higher than default (50), lower than regional providers (10-40)
|
||||
### Fingerprint Computation
|
||||
|
||||
### Environment Variables
|
||||
|
||||
No environment variables required. The provider is self-contained.
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### ✅ Safe for Verification
|
||||
|
||||
The offline verification provider is **safe for verification operations** in offline environments:
|
||||
- Public key verification
|
||||
- Signature validation
|
||||
- Hash computation
|
||||
- Bundle integrity checks
|
||||
|
||||
### ⚠️ Signing Key Protection
|
||||
|
||||
**Private keys used with this provider MUST be protected:**
|
||||
1. **Key Storage:**
|
||||
- Use encrypted key files with strong passphrases
|
||||
- Store in secure filesystem locations with restricted permissions
|
||||
- Consider using OS-level key storage (Windows DPAPI, macOS Keychain)
|
||||
|
||||
2. **Key Rotation:**
|
||||
- Rotate signing keys periodically
|
||||
- Maintain key version tracking for bundle verification
|
||||
|
||||
3. **Access Control:**
|
||||
- Limit file system permissions on private keys (chmod 600 on Unix)
|
||||
- Use separate keys for dev/test/prod environments
|
||||
|
||||
### Deterministic Operations
|
||||
|
||||
The provider ensures deterministic operations where required:
|
||||
- **Hash computation:** SHA-256/384/512 are deterministic
|
||||
- **Signature verification:** Deterministic for given signature and public key
|
||||
- **ECDSA signing:** Uses deterministic nonce generation (RFC 6979) when available
|
||||
|
||||
## Limitations
|
||||
|
||||
1. **No HSM Support:** Keys are software-based, not hardware-backed
|
||||
2. **No Compliance Certification:** Not FIPS 140-2, eIDAS, or other certified implementations
|
||||
3. **Algorithm Limitations:** Only supports algorithms in .NET BCL
|
||||
4. **No Password Hashing:** Use dedicated password hashers instead
|
||||
|
||||
## Migration Guide
|
||||
|
||||
### From Direct System.Security.Cryptography
|
||||
|
||||
**Before:**
|
||||
```csharp
|
||||
using System.Security.Cryptography;
|
||||
|
||||
var hash = SHA256.HashData(dataBytes); // ❌ Direct BCL usage
|
||||
private string ComputeFingerprint(byte[] publicKeyBytes)
|
||||
{
|
||||
var hasher = cryptoProvider.GetHasher("SHA-256");
|
||||
var hash = hasher.ComputeHash(publicKeyBytes);
|
||||
return "sha256:" + Convert.ToHexString(hash).ToLowerInvariant();
|
||||
}
|
||||
```
|
||||
|
||||
**After:**
|
||||
### Out-of-Band Verification Process
|
||||
|
||||
1. **Bundle Reception**: Operator receives `offline-kit.tar.gz` via physical media
|
||||
2. **Checksum Verification**: Compare SHA-256 hash against value published via secure channel
|
||||
```bash
|
||||
sha256sum offline-kit.tar.gz
|
||||
# Compare with published value: a1b2c3d4e5f6...
|
||||
```
|
||||
3. **Bundle Signature Verification**: Extract bundle, verify self-signature using bootstrap public key
|
||||
4. **Trust Anchor Review**: Manual review of trust-anchors.json entries
|
||||
5. **Deployment**: Extract crypto plugin and trust anchors to deployment directory
|
||||

|
||||
|
||||
| Attack Vector | Likelihood | Impact | Mitigation |
|
||||
|---------------|------------|--------|------------|
|
||||
| **Memory Dump** | Medium | High | Use ephemeral keys, minimize key lifetime |
|
||||

|
||||
|
||||
## Best Practices
|
||||
|
||||
### Key Management
|
||||
|
||||
**✅ DO**:
|
||||
- Rotate signing keys every 90 days
|
||||
- Use separate keys for different purposes
|
||||
- Store private keys in memory only
|
||||
- Use ephemeral verifiers for public-key-only scenarios
|
||||
- Audit all key usage events
|
||||
|
||||
**❌ DON'T**:
|
||||
- Reuse keys across environments
|
||||
- Store keys in configuration files
|
||||
- Use RSA keys smaller than 2048 bits
|
||||
- Use SHA-1 or MD5
|
||||
- Bypass fingerprint verification
|
||||
|
||||
### Algorithm Selection
|
||||
|
||||
**Recommended**:
|
||||
1. **ES256** (ECDSA P-256/SHA-256) - Best balance
|
||||
2. **PS256** (RSA-PSS 2048-bit/SHA-256) - For RSA-required scenarios
|
||||
3. **SHA-256** - Default hashing algorithm
|
||||
|
||||
**Avoid**:
|
||||
- ES512 / PS512 - Performance overhead
|
||||
- RS256 / RS384 / RS512 - Legacy PKCS1 padding
|
||||
|
||||
### Performance Optimization
|
||||
|
||||
**Caching**:
|
||||
```csharp
|
||||
using StellaOps.Cryptography;
|
||||
// Cache hashers (thread-safe, reusable)
|
||||
private readonly ICryptoHasher _sha256Hasher;
|
||||
|
||||
var hasher = cryptoRegistry.ResolveHasher("SHA-256");
|
||||
var hash = hasher.Hasher.ComputeHash(dataBytes); // ✅ Provider abstraction
|
||||
public MyService(ICryptoProviderRegistry registry)
|
||||
{
|
||||
_sha256Hasher = registry.ResolveHasher("SHA-256").Hasher;
|
||||
}
|
||||
```
|
||||
|
||||
### From Legacy Crypto Plugins
|
||||
---
|
||||
|
||||
Replace legacy plugin references with OfflineVerificationCryptoProvider:
|
||||
## Troubleshooting
|
||||
|
||||
1. Update `crypto-plugins-manifest.json`
|
||||
2. Replace plugin DI registration
|
||||
3. Update algorithm IDs to standard names (ES256, RS256, etc.)
|
||||
### Common Issues
|
||||
|
||||
## Testing
|
||||
**Issue**: `NotSupportedException: Algorithm 'RS256' is not supported`
|
||||
|
||||
Comprehensive unit tests are available in:
|
||||
`src/__Libraries/__Tests/StellaOps.Cryptography.Tests/OfflineVerificationCryptoProviderTests.cs`
|
||||
**Resolution**:
|
||||
- Verify algorithm ID is exactly `RS256` (case-sensitive)
|
||||
- Check provider supports: `provider.Supports(CryptoCapability.Signing, "RS256")`
|
||||
|
||||
Run tests:
|
||||
```bash
|
||||
dotnet test src/__Libraries/__Tests/StellaOps.Cryptography.Tests/
|
||||
```

||||
- Convert from PEM: `openssl x509 -pubkey -noout -in cert.pem | openssl enc -base64 -d > pubkey.der`
|
||||
|
||||
## Support & Troubleshooting
|
||||
---
|
||||
|
||||
### Provider Not Found
|
||||
**Issue**: Signature verification always returns `false`
|
||||
|
||||
```
|
||||
Error: Crypto provider 'offline-verification' not found
|
||||
```
|
||||
**Resolution**:
|
||||
1. Verify algorithm matches
|
||||
2. Ensure message is identical (byte-for-byte)
|
||||
3. Check public key matches private key
|
||||
4. Enable debug logging
|
||||
|
||||
**Solution:** Ensure plugin is registered in `crypto-plugins-manifest.json` with `enabled: true`

|
||||
|
||||
## Installation
|
||||
|
||||
Add `StellaOps.TestKit` as a project reference to your test project:
|
||||
|
||||
```xml
|
||||
<ItemGroup>
|
||||
<ProjectReference Include="../../../__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj" />
|
||||
</ItemGroup>
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Quick Start Examples
|
||||
|
||||
### 1. Deterministic Time
|
||||
|
||||
Eliminate flaky tests caused by time-dependent logic:
|
||||
|
||||
```csharp
|
||||
using StellaOps.TestKit.Deterministic;
|
||||
using Xunit;
|
||||
|
||||
[Fact]
|
||||
public void Test_ExpirationLogic()
|
||||
{
|
||||
// Arrange: Fix time at a known UTC timestamp
|
||||
using var time = new DeterministicTime(new DateTime(2026, 1, 15, 10, 30, 0, DateTimeKind.Utc));
|
||||
|
||||
var expiresAt = time.UtcNow.AddHours(24);
|
||||
|
||||
// Act: Advance time to just before expiration
|
||||
time.Advance(TimeSpan.FromHours(23));
|
||||
Assert.False(time.UtcNow > expiresAt);
|
||||
|
||||
// Advance past expiration
|
||||
time.Advance(TimeSpan.FromHours(2));
|
||||
Assert.True(time.UtcNow > expiresAt);
|
||||
}
|
||||
```
|
||||
|
||||
**API Reference:**
|
||||
- `DeterministicTime(DateTime initialUtc)` - Create with fixed start time
|
||||
- `UtcNow` - Get current deterministic time
|
||||
- `Advance(TimeSpan duration)` - Move time forward
|
||||
- `SetTo(DateTime newUtc)` - Jump to specific time
|
||||
|
||||
---
|
||||
|
||||
### 2. Deterministic Random
|
||||
|
||||
Reproducible random sequences for property tests and fuzzing:
|
||||
|
||||
```csharp
|
||||
using StellaOps.TestKit.Deterministic;
|
||||
|
||||
[Fact]
|
||||
public void Test_RandomIdGeneration()
|
||||
{
|
||||
// Arrange: Same seed produces same sequence
|
||||
var random1 = new DeterministicRandom(seed: 42);
|
||||
var random2 = new DeterministicRandom(seed: 42);
|
||||
|
||||
// Act
|
||||
var guid1 = random1.NextGuid();
|
||||
var guid2 = random2.NextGuid();
|
||||
|
||||
// Assert: Reproducible GUIDs
|
||||
Assert.Equal(guid1, guid2);
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void Test_Shuffling()
|
||||
{
|
||||
var random = new DeterministicRandom(seed: 100);
|
||||
var array = new[] { 1, 2, 3, 4, 5 };
|
||||
|
||||
random.Shuffle(array);
|
||||
|
||||
// Deterministic shuffle order
|
||||
Assert.NotEqual(new[] { 1, 2, 3, 4, 5 }, array);
|
||||
}
|
||||
```
|
||||
|
||||
**API Reference:**
|
||||
- `DeterministicRandom(int seed)` - Create with seed
|
||||

||||
SpdxVersion = "SPDX-3.0.1",
|
||||
Name = "MySbom",
|
||||
Packages = new[] { new { Name = "Pkg1", Version = "1.0" } }
|
||||
};
|
||||
|
||||
// Verify deterministic serialization
|
||||
CanonicalJsonAssert.IsDeterministic(sbom, iterations: 100);
|
||||
|
||||
// Verify expected hash (golden master)
|
||||
var expectedHash = "abc123..."; // Precomputed SHA-256
|
||||
CanonicalJsonAssert.HasExpectedHash(sbom, expectedHash);
|
||||
}
|
||||
|
||||
[Fact]

Document = new { Id = "VEX-2026-001" },
|
||||
Statements = new[] { new { Vulnerability = "CVE-2026-1234" } }
|
||||
};
|
||||
|
||||
// Deep property verification
|
||||
CanonicalJsonAssert.ContainsProperty(vex, "Document.Id", "VEX-2026-001");
|
||||
CanonicalJsonAssert.ContainsProperty(vex, "Statements[0].Vulnerability", "CVE-2026-1234");
|
||||
}

||||
```csharp
|
||||
using StellaOps.TestKit.Observability;
|
||||
|
||||
[Fact]
|
||||
public async Task Test_TracingBehavior()
|
||||

// Assert traces
|
||||
capture.AssertHasSpan("MyService.DoWork");
|
||||
capture.AssertHasTag("user_id", "123");
|
||||
capture.AssertSpanCount(expectedCount: 3);
|
||||
|

|
||||
|
||||
### 9. Test Categories
|
||||
|
||||
Standardized trait constants for CI lane filtering:
|
||||
|
||||
```csharp
|
||||
using StellaOps.TestKit;
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Unit)]
|
||||
public void FastUnitTest() { }
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Integration)]
|
||||
public async Task SlowIntegrationTest() { }
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Live)]
|
||||
public async Task RequiresExternalServices() { }
|
||||
```
|
||||
|
||||
**CI Lane Filtering:**
|
||||
|
||||
```bash
|
||||
# Run only unit tests (fast, no dependencies)
|
||||
dotnet test --filter "Category=Unit"
|
||||
|
||||
# Run all tests except Live
|
||||
dotnet test --filter "Category!=Live"
|
||||
|
||||
# Run Integration + Contract tests
|
||||
dotnet test --filter "Category=Integration|Category=Contract"
|
||||
```
|
||||
|
||||
**Available Categories:**
|
||||
- `Unit` - Fast, in-memory, no external dependencies
|
||||
- `Property` - FsCheck/generative testing
|
||||
- `Snapshot` - Golden master regression
|
||||
- `Integration` - Testcontainers (PostgreSQL, Valkey)
|
||||
- `Contract` - API/WebService contract tests
|
||||
- `Security` - Cryptographic validation
|
||||
- `Performance` - Benchmarking, load tests
|
||||
- `Live` - Requires external services (disabled in CI by default)

### 1. Always Use TestCategories
|
||||
|
||||
Tag every test with the appropriate category:
|
||||
|
||||
```csharp
|
||||
[Fact, Trait("Category", TestCategories.Unit)]
|
||||
public void MyUnitTest() { }
|
||||
```
|
||||
|
||||
This enables CI lane filtering and improves test discoverability.
|
||||
|
||||
### 2. Prefer Deterministic Primitives
|
||||
|
||||
Avoid `DateTime.UtcNow`, `Guid.NewGuid()`, `Random` in tests. Use TestKit alternatives:
|
||||
|
||||
```csharp
|
||||
// ❌ Flaky test (time-dependent)
|
||||
var expiration = DateTime.UtcNow.AddHours(1);
|
||||
|
||||
// ✅ Deterministic test
|
||||
using var time = new DeterministicTime(DateTime.UtcNow);
|
||||
var expiration = time.UtcNow.AddHours(1);
|
||||
```
|
||||
|
||||
### 3. Use Snapshot Tests for Complex Outputs
|
||||
|
||||
For large JSON outputs (SBOM, VEX, attestations), snapshot testing is more maintainable than manual assertions:
|
||||
|
||||
```csharp
|
||||
// ❌ Brittle manual assertions
|
||||
Assert.Equal("SPDX-3.0.1", sbom.SpdxVersion);
|
||||
Assert.Equal(42, sbom.Packages.Count);
|
||||
// ...hundreds of assertions...
|
||||
|
||||
// ✅ Snapshot testing
|
||||
SnapshotAssert.MatchesSnapshot(sbom, "MySbomSnapshot");
|
||||
```
|
||||
|
||||
### 4. Isolate Integration Tests
|
||||
|
||||
Use TestCategories to separate fast unit tests from slow integration tests:
|
||||
|
||||
```csharp
|
||||
[Fact, Trait("Category", TestCategories.Unit)]
|
||||
public void FastTest() { /* no external dependencies */ }
|
||||
|
||||
[Fact, Trait("Category", TestCategories.Integration)]
|
||||
public async Task SlowTest() { /* uses PostgresFixture */ }
|
||||
```
|
||||
|
||||
In CI, run Unit tests first for fast feedback, then Integration tests in parallel.
|
||||
|
||||
### 5. Document Snapshot Baselines
|
||||
|
||||
When updating snapshots (`UPDATE_SNAPSHOTS=1`), add a commit message explaining why:
|
||||
|
||||
```bash
|
||||
git commit -m "Update SBOM snapshot: added new package metadata fields"
|
||||
```
|
||||
|
||||
This helps reviewers understand intentional vs. accidental changes.
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Snapshot Mismatch
|
||||
|
||||
**Error:** `Snapshot 'MySbomSnapshot' does not match expected.`
|
||||
|
||||
**Solution:**
|
||||
1. Review diff manually (check `Snapshots/MySbomSnapshot.json`)
|
||||
2. If change is intentional: `UPDATE_SNAPSHOTS=1 dotnet test`
|
||||
3. Commit updated snapshot with explanation
|
||||
|
||||
### Testcontainers Failure
|
||||
|
||||
**Error:** `Docker daemon not running`
|
||||
|
||||
**Solution:**
|
||||
- Ensure Docker Desktop is running
|
||||
- Verify `docker ps` works in terminal
|
||||
- Check Testcontainers logs: `TESTCONTAINERS_DEBUG=1 dotnet test`
|
||||
|
||||
### Determinism Failure
|
||||
|
||||
**Error:** `CanonicalJsonAssert.IsDeterministic failed: byte arrays differ`
|
||||
|
||||
**Root Cause:** Non-deterministic data in serialization (e.g., random GUIDs, timestamps)
|
||||
|
||||
**Solution:**
|
||||
- Use `DeterministicTime` and `DeterministicRandom`
|
||||
- Ensure all data is seeded or mocked
|
||||
- Check for `DateTime.UtcNow` or `Guid.NewGuid()` calls
|
||||
|
||||

|
||||
|
||||
## Migration Guide (Existing Tests)
|
||||
|
||||
### Step 1: Add TestKit Reference
|
||||
|
||||
```xml
|
||||
<ProjectReference Include="../../../__Libraries/StellaOps.TestKit/StellaOps.TestKit.csproj" />
|
||||
```
|
||||
|
||||
### Step 2: Replace Time-Dependent Code
|
||||
|
||||
**Before:**
|
||||
```csharp
|
||||
var now = DateTime.UtcNow;
|
||||
```
|
||||
|
||||
**After:**
|
||||
```csharp
|
||||
using var time = new DeterministicTime(DateTime.UtcNow);
|
||||
var now = time.UtcNow;
|
||||
```
|
||||
|
||||
### Step 3: Add Test Categories
|
||||
|
||||
```csharp
|
||||
[Fact] // Old
|
||||
[Fact, Trait("Category", TestCategories.Unit)] // New
|
||||
```
|
||||
|
||||
### Step 4: Adopt Snapshot Testing (Optional)
|
||||
|
||||
For complex JSON assertions, replace manual checks with snapshots:
|
||||
|
||||
```csharp
|
||||
// Old
|
||||
Assert.Equal(expected.SpdxVersion, actual.SpdxVersion);
|
||||
// ...
|
||||
|
||||
// New
|
||||
SnapshotAssert.MatchesSnapshot(actual, "TestName");
|
||||
```
|
||||

||||

# PostgreSQL operations
|
||||
|
||||
Purpose
|
||||
- Operate the canonical PostgreSQL control plane with deterministic behavior.
|
||||
|
||||
Schema topology
|
||||
- Per-module schemas: authority, vuln, vex, scheduler, notify, policy, concelier, audit.
|
||||
- Tenant isolation enforced via tenant_id and RLS policies.
|
||||
|
||||
Performance setup
|
||||
- Enable pg_stat_statements for query analysis.
|
||||
- Tune shared_buffers, effective_cache_size, work_mem, and WAL sizes per host.
|
||||
- Use PgBouncer in transaction pooling mode for high concurrency.
|
||||
|
||||
Session defaults
|
||||
- SET app.tenant_id per connection.
|
||||
- SET timezone to UTC.
|
||||
- Enforce statement_timeout for long-running queries.
|
||||
|
||||
Query analysis
|
||||
- Use pg_stat_statements to find high total and high mean latency queries.
|
||||
- Use EXPLAIN ANALYZE with BUFFERS to detect missing indexes.
|
||||
|
||||
Backups and restore
|
||||
- Use scheduled logical or physical backups with tested restore paths.
|
||||
- Keep PITR capability where required by retention policies.
|
||||
- Validate backups with deterministic restore tests.
|
||||
|
||||
Monitoring
|
||||
- Track connection count, replication lag, and slow query rates.
|
||||
- Alert on pool saturation and replication delays.

# PostgreSQL patterns
|
||||
|
||||
Row-level security (RLS)
|
||||
- Require tenant context via app.tenant_id session setting.
|
||||
- Policies filter by tenant_id on all tenant-scoped tables.
|
||||
- Admin operations use explicit bypass roles and audited access.
|
||||
|
||||
Validating RLS
|
||||
- Run staging tests that attempt cross-tenant reads and writes.
|
||||
- Use deterministic replay tests for RLS regressions.
|
||||
|
||||
Bitemporal unknowns
|
||||
- Store current and historical states with valid_from and valid_to.
|
||||
- Support point-in-time queries and deterministic ordering.
|
||||
|
||||
Time-based partitioning
|
||||
- Partition high-volume tables by time.
|
||||
- Pre-create future partitions and archive old partitions.
|
||||
- Use deterministic maintenance checklists for partition health.
|
||||
|
||||
Generated columns
|
||||
- Use generated columns for derived flags and query optimization.
|
||||
- Add columns via migrations and backfill deterministically.
|
||||
|
||||
Troubleshooting
|
||||
- RLS failures: verify tenant context and policy attachment.
|
||||
- Partition issues: check missing partitions and default tables.
|
||||
- Bitemporal queries: confirm valid time windows and index usage.

- verify_runs_total{tenant,initiator}
|
||||
- verify_duration_seconds{tenant,initiator}
|
||||
|
||||
Alert guidance
|
||||
- Violation spike: increase(aoc_violation_total[15m]) > 0 for critical sources.
|
||||
- Stale ingestion: no growth in ingestion_write_total for > 60 minutes.
|
||||
- Signature drop: rising ingestion_signature_verified_total{result="fail"}.
|
||||
|
||||
Health snapshot endpoint
|
||||
- GET /obs/excititor/health returns ingest, link, signature, conflict status.
|
||||
- Settings control warning and critical thresholds for lag, coverage, and conflict ratio.
|
||||
|
||||
Trace taxonomy
|
||||
- ingest.fetch, ingest.transform, ingest.write
|
||||
- aoc.guard for violations
|
||||
- verify.run for verification jobs
|
||||
|
||||
Log fields
|
||||
- traceId, tenant, source.vendor, upstream.upstreamId
|
||||
- contentHash, violation.code, verification.window
|
||||
- Correlation headers: X-Stella-TraceId, X-Stella-CorrelationId
|
||||
|
||||
Advisory AI chunk metrics
|
||||
- advisory_ai_chunk_requests_total
|
||||
- advisory_ai_chunk_latency_milliseconds
|
||||
- advisory_ai_chunk_segments
|
||||
- advisory_ai_chunk_sources
|
||||
- advisory_ai_guardrail_blocks_total
|
||||
|
||||
Dashboards
|
||||
- AOC ingestion health: sources overview, violations, signature rate, supersedes depth.
|
||||
- Offline mode dashboard from offline snapshots.
|
||||
|
||||
Offline posture
|
||||
- Metrics exporters write to local Prometheus snapshots in offline kits.
|
||||
- CLI verification reports are hashed and archived.
|
||||
- Dashboards support offline data sources.

# Logging standards
|
||||
|
||||
Goals
|
||||
- Deterministic, structured logs for all services.
|
||||
- Safe for tenant isolation and offline review.
|
||||
|
||||
Required fields
|
||||
- timestamp (UTC ISO-8601)
|
||||
- tenant, workload, env, region, version
|
||||
- level (debug, info, warn, error, fatal)
|
||||
- category and operation
|
||||
- trace_id, span_id, correlation_id when present
|
||||
- message (concise, no secrets)
|
||||
- status (ok, error, fault, throttle)
|
||||
- error.code, error.message (redacted), retryable when status is not ok
|
||||
|
||||
Optional fields
|
||||
- resource, http.method, http.status_code, duration_ms
|
||||
- host, pid, thread
|
||||
|
||||
Offline kit import fields
|
||||
- tenant_id, bundle_type, bundle_digest, bundle_path
|
||||
- manifest_version, manifest_created_at
|
||||
- force_activate, force_activate_reason
|
||||
- result, reason_code, reason_message
|
||||
- quarantine_id, quarantine_path
|
||||
|
||||
Redaction rules
|
||||
- Never log auth headers, tokens, passwords, private keys, or full bodies.
|
||||
- Redact to "[redacted]" and add redaction.reason.
|
||||
- Hash low-cardinality identifiers and mark hashed=true.
|
||||
|
||||
Determinism and offline posture
|
||||
- NDJSON with LF endings; UTC timestamps only.
|
||||
- No external enrichment; rely on bundled metadata.
|
||||
|
||||
Sampling and rate limits
|
||||
- Info logs rate-limited per component; warn and error never sampled.
|
||||
- Audit logs are never sampled and include actor, action, target, result.

||||
|
||||
Alert examples
|
||||
- Error rate: rate(errors_total[5m]) / rate(http_requests_total[5m]) > 0.02
|
||||
- Latency regression: p95 http_request_duration_seconds > 0.3s
|
||||
- Queue backlog: queue_depth > 1000 for 5 minutes
|
||||
- Job failures: rate(worker_jobs_total{status="failed"}[10m]) > 0.01
|
||||
|
||||
UX KPIs (triage TTFS)
|
||||
- P95 first evidence <= 1.5s; skeleton <= 0.2s.
|
||||
- Clicks-to-closure median <= 6.
|
||||
- Evidence completeness >= 90% (>= 3.6/4).

|
||||
- SLO targets: warning above 1.0%, critical above 2.5%, engine drift > 0%
|
||||
|
||||
Hygiene
|
||||
- Tag metrics with tenant, workload, env, region, version.
|
||||
- Keep metric names stable and namespace custom metrics per module.
|
||||
- Use deterministic bucket boundaries and consistent units.

# Observability standards
|
||||
|
||||
Common envelope fields
|
||||
- Trace context: trace_id, span_id, trace_flags; propagate W3C traceparent and baggage.
|
||||
- Tenant and workload: tenant, workload (service), region, env, version.
|
||||
- Subject: component, operation, resource (purl or uri when safe).
|
||||
- Timing: UTC ISO-8601 timestamp; durations in milliseconds.
|
||||
- Outcome: status (ok, error, fault, throttle), error.code, redacted error.message, retryable.
|
||||
|
||||
Scrubbing policy
|
||||
- Denylist PII and secrets: emails, tokens, auth headers, private keys, passwords.
|
||||
- Redact to "[redacted]" and add redaction.reason (secret, pii, tenant_policy).
|
||||
- Hash low-cardinality identifiers with sha256 and mark hashed=true.
|
||||
- Never log full request or response bodies; store hashes and lengths only.
|
||||
|
||||
Sampling defaults
|
||||
- Traces: 10% non-prod, 5% prod; always sample error or audit spans.
|
||||
- Logs: info logs rate-limited; warn and error never sampled.
|
||||
- Metrics: never sampled; stable histogram buckets per component.
|
||||
|
||||
Redaction override
|
||||
- Overrides require a ticket id and are time-bound.
|
||||
- Config: telemetry.redaction.overrides and telemetry.redaction.override_ttl (default 24h).
|
||||
- Emit telemetry.redaction.audit with actor, fields, and TTL.
|
||||
|
||||
Determinism and offline
|
||||
- No external enrichers; use bundled service maps and tenant metadata only.
|
||||
- Export ordering: timestamp, workload, operation.
|
||||
- Always use UTC; NDJSON for log exports.

# Telemetry controls and propagation
|
||||
|
||||
Bootstrap wiring
|
||||
- AddStellaOpsTelemetry wires metrics and tracing with deterministic defaults.
|
||||
- Disable exporters when sealed or when egress is not allowed.
|
||||
|
||||
Minimal host wiring (example)
|
||||
```csharp
|
||||
builder.Services.AddStellaOpsTelemetry(
|
||||
builder.Configuration,
|
||||
serviceName: "StellaOps.SampleService",
|
||||
serviceVersion: builder.Configuration["VERSION"],
|
||||
configureOptions: options =>
|
||||
{
|
||||
options.Collector.Enabled = builder.Configuration.GetValue<bool>("Telemetry:Collector:Enabled", true);
|
||||
options.Collector.Endpoint = builder.Configuration["Telemetry:Collector:Endpoint"];
|
||||
options.Collector.Protocol = TelemetryCollectorProtocol.Grpc;
|
||||
},
|
||||
configureMetrics: m => m.AddAspNetCoreInstrumentation(),
|
||||
configureTracing: t => t.AddHttpClientInstrumentation());
|
||||
```
|
||||
|
||||
Propagation rules
|
||||
- HTTP headers: traceparent, tracestate, x-stella-tenant, x-stella-actor, x-stella-imposed-rule.
|
||||
- gRPC metadata: stella-tenant, stella-actor, stella-imposed-rule.
|
||||
- Tenant is required for all requests except sealed diagnostics jobs.
|
||||
|
||||
Metrics helper expectations
|
||||
- Golden signals: http.server.duration, http.client.duration, messaging.operation.duration,
|
||||
job.execution.duration, runtime.gc.pause, db.call.duration.
|
||||
- Mandatory tags: tenant, service, endpoint or operation, result (ok|error|cancelled|throttled), sealed.
|
||||
- Cardinality guard trims tag values to 64 chars and caps distinct values per key.
|
||||
|
||||
Scrubbing configuration
|
||||
- Telemetry:Scrub:Enabled (default true)
|
||||
- Telemetry:Scrub:Sealed (forces scrubbing when sealed)
|
||||
- Telemetry:Scrub:HashSalt (optional)
|
||||
- Telemetry:Scrub:MaxValueLength (default 256)
|
||||
|
||||
Sealed mode behavior
|
||||
- Disable external exporters; use memory or file OTLP.
|
||||
- Tag sealed=true and scrubbed=true on all records.
|
||||
- Sampling capped by Telemetry:Sealed:MaxSamplingPercent.
|
||||
- File exporter rotates deterministically and enforces 0600 permissions.
|
||||
|
||||
Sealed mode config keys
|
||||
- Telemetry:Sealed:Enabled
|
||||
- Telemetry:Sealed:Exporter (memory|file)
|
||||
- Telemetry:Sealed:FilePath
|
||||
- Telemetry:Sealed:MaxBytes
|
||||
- Telemetry:Sealed:MaxSamplingPercent
|
||||
|
||||
Incident mode (CLI)
|
||||
- Flag: --incident-mode
|
||||
- Config: Telemetry:Incident:Enabled and Telemetry:Incident:TTL
|
||||
- State file: ~/.stellaops/incident-mode.json (0600 permissions)
|
||||
- Emits telemetry.incident.activated and telemetry.incident.expired audit events.
|
||||
|
||||
Determinism
|
||||
- UTC timestamps and stable ordering for OTLP exports.
|
||||
- No external enrichment in sealed mode.

# Tracing standards
|
||||
|
||||
Goals
|
||||
- Consistent distributed tracing across services, workers, and CLI.
|
||||
- Safe for offline and air-gapped deployments.
|
||||
|
||||
Context propagation
|
||||
- Use W3C traceparent and baggage only.
|
||||
- Preserve incoming trace_id and create child spans per operation.
|
||||
- For async work, attach stored trace context as links rather than a new parent.
|
||||
|
||||
Span conventions
|
||||
- Names use <component>.<operation> (example: policy.evaluate).
|
||||
- Required attributes: tenant, workload, env, region, version, operation, status.
|
||||
- HTTP spans: http.method, http.route, http.status_code, net.peer.name, net.peer.port.
|
||||
- DB spans: db.system, db.name, db.operation, db.statement (no literals).
|
||||
- Message spans: messaging.system, messaging.destination, messaging.operation, messaging.message_id.
|
||||
- Errors: status=error with error.code, redacted error.message, retryable.
|
||||
|
||||
Sampling
|
||||
- Default head sampling: 10% non-prod, 5% prod.
|
||||
- Always sample error or audit spans.
|
||||
- Override via Tracing__SampleRate per service.
|
||||
|
||||
Offline posture
|
||||
- No external exporters; emit OTLP to local collector or file.
|
||||
- UTC timestamps only.

||||
Alerting hints
|
||||
- ConsoleLatencyHigh when ui_route_render_seconds p95 exceeds target.
|
||||
- BackendLatencyHigh when ui_request_duration_seconds spikes.
|
||||
- TenantSwitchFailures when ui_dpop_failure_total increases.

# Key rotation
|
||||
|
||||
Purpose
|
||||
- Rotate signing keys without invalidating historical DSSE proofs.
|
||||
|
||||
Principles
|
||||
- Do not mutate old DSSE envelopes.
|
||||
- Keep key history; revoke instead of delete.
|
||||
- Publish key material to trust anchors and mirrors.
|
||||
- Audit all key lifecycle events.
|
||||
|
||||
Key profiles (examples)
|
||||
- default: SHA256-ED25519
|
||||
- fips: SHA256-ECDSA-P256
|
||||
- gost: GOST-R-34.10-2012
|
||||
- sm2: SM2-P256
|
||||
- pqc: ML-DSA-65
|
||||
|
||||
Rotation workflow
|
||||
1. Generate a new key in the configured keystore.
|
||||
2. Add the key to the trust anchor without removing old keys.
|
||||
3. Run a transition period where both keys verify.
|
||||
4. Revoke the old key with an effective date.
|
||||
5. Publish updated key material to attestation feeds or mirrors.
|
||||
|
||||
Trust anchors
|
||||
- Scoped by PURL pattern and allowed predicate types.
|
||||
- Store allowedKeyIds, revokedKeys, and keyHistory with timestamps.
|
||||
|
||||
Verification with key history
|
||||
- Verify signatures using the key valid at the time of signing.
|
||||
- Revoked keys remain valid for pre-revocation attestations.
|
||||
|
||||
Emergency revocation
|
||||
- Revoke compromised keys immediately and publish updated anchors.
|
||||
- Re-issue trust bundles and notify downstream verifiers.
|
||||
|
||||

||||
- Verify DSSE bundles and transparency proofs for scan and score evidence.
|
||||
|
||||
Components
|
||||
- DSSE envelope and signature bundle.
|
||||
- Certificate chain and trust roots.
|
||||
- Rekor inclusion proof and checkpoint when online.
|
||||
|
||||
Basic verification
|
||||
- Verify DSSE signature against trusted roots.
|
||||
- Confirm subject digest matches expected artifact.
|
||||
- Validate Merkle inclusion proof when available.
|
||||
|
||||
Offline verification
|
||||
- Use embedded proofs and local trust bundles.

|
||||
- Record verification results in timeline events.
|
||||
|
||||
Transparency log integration
|
||||

|
||||
- When Rekor is unavailable, rely on cached checkpoint and proofs.
|
||||
|
||||
Troubleshooting cues
|
||||
- DSSE signature invalid: check key rotation or trust anchors.
|
||||
- Merkle root mismatch: verify checkpoint and bundle integrity.
|
||||
- Certificate chain failure: refresh trust roots.
|
||||
|
||||
Monitoring
|
||||
- Track verification latency and failure counts.
|
||||
- Alert on certificate expiry or rising verification failures.

# Orchestrator runbook
|
||||
|
||||
Pre-flight
|
||||
- Verify database and queue backends are healthy.
|
||||
- Confirm tenant allowlist and orchestrator scopes in Authority.
|
||||
- Ensure plugin bundles are present and signatures verified.
|
||||
|
||||
Common operations
|
||||
- Start a run via API or CLI.
|
||||

||||
- Stream status via WebSocket or CLI.
|
||||
- Export run ledger as NDJSON for audit.
|
||||
|
||||
Incident response
|
||||
- Queue backlog: scale workers and drain oldest first.
|
||||
- Repeated failures: inspect error codes and inputsHash; roll back DAG version.
|
||||
- Plugin auth errors: rotate secrets and warm caches.
|
||||
|
||||

# Attestation workflow
|
||||
|
||||
Purpose
|
||||
- Ensure all exported evidence includes DSSE signatures and transparency proofs.
|
||||
- Provide deterministic verification for online and air-gapped environments.
|
||||
|
||||
Workflow overview
|
||||
- Producer emits a payload and requests signing.
|
||||
- Signer validates policy and signs with tenant or keyless credentials.
|
||||
- Attestor wraps the payload in DSSE, records transparency data, and publishes bundles.
|
||||
- Export Center and Evidence Locker embed bundles in export artifacts.
|
||||
- Verifiers (CLI, services, auditors) validate signatures and proofs.
|
||||
|
||||
Payload types
|
||||
- StellaOps.BuildProvenance@1
|
||||
- StellaOps.SBOMAttestation@1
|
||||
- StellaOps.ScanResults@1
|
||||
- StellaOps.PolicyEvaluation@1
|
||||
- StellaOps.VEXAttestation@1
|
||||
- StellaOps.RiskProfileEvidence@1
|
||||
- StellaOps.PromotionAttestation@1
|
||||
|
||||
Signing and storage controls
|
||||
- Default is short-lived keyless signing; tenant KMS keys are supported.
|
||||
- Ed25519 and ECDSA P-256 are supported.
|
||||
- Payloads must exclude PII and secrets; redaction is required before signing.
|
||||
- Evidence Locker stores immutable copies with retention and legal hold.
|
||||
|
||||
Verification steps
|
||||
- Verify DSSE signature against trusted roots.
|
||||
- Confirm subject digest matches expected artifact.
|
||||
- Verify transparency proof when available.
|
||||
- Enforce freshness using attestation.max_age_days policy.
|
||||
- Record verification results in timeline events.
|
||||
|
||||
Offline posture
|
||||
- Bundles include DSSE, transparency proofs, and certificate chains.
|
||||
- Offline verification uses embedded proofs and cached trust roots.
|
||||
- Pending transparency entries are replayed when connectivity returns.

# Provenance backfill
|
||||
|
||||
Purpose
|
||||
- Backfill missing provenance records with deterministic ordering.
|
||||
|
||||
Inputs
|
||||
- Attestation inventory (NDJSON) with subject and digest data.
|
||||
- Subject to Rekor map for resolving transparency entries.
|
||||
|
||||
Procedure
|
||||
1. Validate inventory records (UUID or ULID and digest formats).
|
||||
2. Resolve each subject to a Rekor entry; record gaps and skip if missing.
|
||||
3. Emit backfilled provenance events using a backfill mode that preserves ordering.
|
||||
4. Log every backfilled subject and Rekor digest pair as NDJSON.
|
||||
5. Repeat until gaps are zero and record completion in audit logs.
|
||||
|
||||
Determinism
|
||||
- Sort by subject then Rekor entry before processing.
|
||||
- Use canonical JSON writers and UTC timestamps.

# Rekor submission policy
|
||||
|
||||
Purpose
|
||||
- Balance transparency log usage with budget limits and offline safety.
|
||||
|
||||
Submission tiers
|
||||
- Tier 1: graph-level attestations per scan (default).
|
||||
- Tier 2: edge bundle attestations for escalations.
|
||||
|
||||
Budgets
|
||||
- Hourly limits for graph submissions.
|
||||
- Daily limits for edge bundle submissions.
|
||||
- Burst windows for Tier 1 only.
|
||||
|
||||
Enforcement
|
||||
- Queue excess submissions with backpressure.
|
||||
- Retry failed submissions with backoff.
|
||||
- Store overflow locally for later submission.
|
||||
|
||||
Offline behavior
|
||||
- Queue submissions in attestor.rekor_offline_queue.
|
||||
- Bundle pending submissions in offline kits.
|

# Promotion attestations
|
||||
|
||||
Purpose
|
||||
- Capture promotion-time evidence in a DSSE predicate for offline audit.
|
||||
|
||||
Predicate: stella.ops/promotion@v1
|
||||
- subject: image name and digest.
|
||||
- materials: SBOM and VEX digests with format and OCI uri.
|
||||
- promotion: from, to, actor, timestamp, pipeline, ticket, notes.
|
||||
- rekor: uuid, logIndex, inclusionProof, checkpoint.
|
||||
- attestation: bundle_sha256 and optional witness.
|
||||
|
||||
Producer workflow
|
||||
1. Resolve and freeze image digest.
|
||||
2. Hash SBOM and VEX artifacts and publish to OCI if needed.
|
||||
3. Obtain Rekor inclusion proof and checkpoint.
|
||||
4. Build promotion predicate JSON.
|
||||
5. Sign with Signer to produce DSSE bundle.
|
||||
6. Store bundle in Evidence Locker and Export Center.
|
||||
|
||||
Verification flow
|
||||
- Verify DSSE signature using trusted roots.
|
||||
- Verify Merkle inclusion using the embedded proof and checkpoint.
|
||||
- Hash SBOM and VEX artifacts and compare to materials digests.
|
||||
- Confirm promotion metadata and ticket evidence.
|
||||
|
||||
Storage and APIs
|
||||
- Signer: /api/v1/signer/sign/dsse
|
||||
- Attestor: /api/v1/rekor/entries
|
||||
- Export Center: serves promotion bundles for offline kits
|
||||
- Evidence Locker: long-term retention of DSSE and proofs
|
||||
|
||||
Security considerations
|
||||
- Promotion metadata is tenant scoped.
|
||||
- Rekor proofs must be embedded for air-gap verification.
|
||||
- Key rotation follows Signer and Authority policies.

# Risk factors
|
||||
|
||||
Purpose
|
||||
- Define factor catalog and normalization rules for risk scoring.
|
||||
|
||||
Factor catalog (examples)
|
||||
- CVSS or exploit likelihood: numeric 0-10 normalized to 0-1.
|
||||
- KEV flag: boolean boost with provenance.
|
||||
- Reachability: numeric with entrypoint and path provenance.
|
||||
- Runtime facts: categorical or numeric with trace references.
|
||||
- Fix availability: vendor status and mitigation context.
|
||||
- Asset criticality: tenant or service criticality signals.
|
||||
- Provenance trust: categorical trust tier with attestation hash.
|
||||
- Custom overrides: scoped, expiring, and auditable.
|
||||
|
||||
Normalization rules
|
||||
- Validate against profile signal types and transforms.
|
||||
- Clamp numeric inputs to 0-1 and record original values in provenance.
|
||||
- Apply TTL or decay deterministically; drop expired signals.
|
||||
- Precedence: signed over unsigned, runtime over static, newer over older.
|
||||
|
||||
Determinism and ordering
|
||||
- Sort factors by factor type, source, then timestamp.
|
||||
- Hash fixtures and record SHA256 in docs/risk/samples/factors/.

# Risk formulas
|
||||
|
||||
Purpose
|
||||
- Define how normalized factors combine into a risk score and severity.
|
||||
|
||||
Formula building blocks
|
||||
- Weighted sum with per-factor caps and family caps.
|
||||
- Normalize raw score to 0-1 and apply gates.
|
||||
- VEX gate: not_affected can short-circuit to 0.0.
|
||||
- CVSS + KEV boost: clamp01((cvss/10) + kev_bonus).
|
||||
- Trust gates: fail or down-weight low-trust provenance.
|
||||
- Decay: apply time-based decay to stale signals.
|
||||
- Overrides: tenant or asset overrides with expiry and audit.
|
||||
|
||||
Severity mapping
|
||||
- Map normalized_score to critical, high, medium, low, informational.
|
||||
- Store band rationale in explainability output.
|
||||
|
||||
Determinism
|
||||
- Stable factor ordering before aggregation.
|
||||
- Fixed precision (example: 4 decimals) before severity mapping.
|
||||
- Hash fixtures and record SHA256 in docs/risk/samples/formulas/.

# Risk overview
|
||||
|
||||
Purpose
|
||||
- Explain risk scoring concepts, lifecycle, and artifacts.
|
||||
- Preserve deterministic, provenance-backed outputs.
|
||||
|
||||
Core concepts
|
||||
- Signals become evidence after validation and normalization.
|
||||
- Profiles define weights, thresholds, overrides, and severity mapping.
|
||||
- Formulas aggregate normalized factors into a 0-1 score.
|
||||
- Provenance carries source hashes and attestation references.
|
||||
|
||||
Lifecycle
|
||||
1. Submit a risk job with tenant, context, profile, and findings.
|
||||
2. Ingest evidence from scanners, reachability, VEX, runtime signals, and KEV.
|
||||
3. Normalize and dedupe by provenance hash.
|
||||
4. Evaluate profile rules, gates, and overrides.
|
||||
5. Assign severity band and emit explainability output.
|
||||
6. Export bundles with profile hash and evidence references.
|
||||
|
||||
Artifacts
|
||||
- Profile schema: id, version, signals, weights, overrides, metadata, provenance.
|
||||
- Job and result fields: job_id, profile_hash, normalized_score, severity.
|
||||
- Explainability envelope: signal_values, signal_contributions, gates_triggered.
|
||||
|
||||
Determinism and offline posture
|
||||
- Stable ordering for factors and contributions.
|
||||
- Fixed precision math with UTC timestamps only.
|
||||
- Fixtures and hashes live under docs/risk/samples/.

# Risk profiles
|
||||
|
||||
Purpose
|
||||
- Define profile schema, lifecycle, and governance for risk scoring.
|
||||
|
||||
Schema essentials
|
||||
- id, version, description, signals[], weights, metadata.
|
||||
- signals[] fields: name, source, type (numeric, boolean, categorical), path, transform, unit.
|
||||
- overrides: severity rules and decision rules.
|
||||
- Optional: extends, rollout flags, valid_from, valid_until.
|
||||
|
||||
Severity levels
|
||||
- critical, high, medium, low, informational.
|
||||
|
||||
Lifecycle
|
||||
1. Author profiles in Policy Studio.
|
||||
2. Simulate against deterministic fixtures.
|
||||
3. Review and approve with DSSE signatures.
|
||||
4. Promote and activate in Policy Engine.
|
||||
5. Roll back by activating a previous version.
|
||||
|
||||
Governance and determinism
|
||||
- Profiles are immutable after promotion.
|
||||
- Each version carries a profile_hash and signed manifest entry.
|
||||
- Simulation and production share the same evaluation codepath.
|
||||
- Offline bundles include profiles and fixtures with hashes.
|
||||
|
||||
Explainability and observability
|
||||
- Emit per-factor contributions with stable ordering.
|
||||
- Track evaluation latency, factor coverage, profile hit rate, and override usage.

# Multi-tenancy
|
||||
|
||||
Purpose
|
||||
- Ensure strict tenant isolation across APIs, storage, and observability.
|
||||
|
||||
Tenant lifecycle
|
||||
- Create tenants with scoped roles and default policies.
|
||||
- Suspend or retire tenants with audit records.
|
||||
- Migrations and data retention follow governance policy.
|
||||
|
||||
Isolation model
|
||||
- Tokens carry tenant identifiers and scopes.
|
||||
- APIs require tenant headers; cross-tenant actions are explicit.
|
||||
- Datastores enforce tenant_id and RLS where supported.
|
||||
|
||||
Observability
|
||||
- Metrics, logs, and traces always include tenant.
|
||||
- Cross-tenant access attempts emit audit events.
|
||||
|
||||
Offline posture
|
||||
- Offline bundles are tenant scoped.
|
||||
- Tenant list in offline mode is limited to snapshot contents.

# Row-level security
|
||||
|
||||
Purpose
|
||||
- Enforce tenant isolation at the database level with RLS policies.
|
||||
|
||||
Strategy
|
||||
- Apply RLS to tenant-scoped tables and views.
|
||||
- Require app.tenant_id session setting on every connection.
|
||||
- Deny access when tenant context is missing.
|
||||
|
||||
Policy evaluation
|
||||
- Policies filter rows by tenant_id and optional scope.
|
||||
- Admin bypass uses explicit roles with audited access.
|
||||
|
||||
Validation
|
||||
- Run cross-tenant read and write tests in staging.
|
||||
- Include RLS checks in deterministic replay suites.

# Timeline forensics
|
||||
|
||||
Purpose
|
||||
- Provide an append-only event ledger for audit, replay, and incident analysis.
|
||||
- Support deterministic exports for offline review.
|
||||
|
||||
Event model
|
||||
- event_id (ULID)
|
||||
- tenant
|
||||
- timestamp (UTC ISO-8601)
|
||||
- category (scanner, policy, runtime, evidence, notify)
|
||||
- details (JSON payload)
|
||||
- trace_id for correlation
|
||||
|
||||
Event kinds
|
||||
- scan.completed
|
||||
- policy.verdict
|
||||
- attestation.verified
|
||||
- evidence.ingested
|
||||
- notify.sent
|
||||
- runtime.alert
|
||||
- redaction_notice (compensating event)
|
||||
|
||||
APIs
|
||||
- GET /api/v1/timeline/events with filters for tenant, category, time window, trace_id.
|
||||
- GET /api/v1/timeline/events/{id} for a single event.
|
||||
- GET /api/v1/timeline/export for NDJSON exports.
|
||||
- Headers: X-Stella-Tenant, optional X-Stella-TraceId, If-None-Match.
|
||||
|
||||
Query guidance
|
||||
- Use category plus trace_id to track scan to policy to notify flow.
|
||||
- Use tenant and timestamp ranges for SLA audits.
|
||||
- CLI parity: stella timeline list mirrors the API.
|
||||
|
||||
Retention and redaction
|
||||
- Append-only storage; no deletes.
|
||||
- Redactions use redaction_notice events that reference the superseded event.
|
||||
- Retention is tenant-configurable and exported weekly to cold storage.
|
||||
|
||||
Offline posture
|
||||
- Offline kits include timeline exports for compliance review.
|
||||
- Exports include stable ordering and manifest hashes.

- Tiers group states by entropy ranges.
|
||||
- The aggregate tier is the maximum severity present.
|

- Risk score adds an entropy-based modifier.
|
||||
- Tiers group states by entropy ranges (T1 high to T4 negligible).
|

Tier ranges (example)
|
||||
- T1: 0.7 to 1.0, blocks not_affected.
|
||||
- T2: 0.4 to 0.69, warns on not_affected.

||||
|
||||
Expected behavior
|
||||
- Normal load returns 200 OK.
|
||||
- High load returns 429 with Retry-After.
|
||||
- Critical load returns 503 with Retry-After.
|
||||
- Recovery within 30 seconds, zero data loss.
|
||||
|
||||
Metrics
|
||||
- http_requests_total{status}

# StellaOps.TestKit
|
||||
|
||||
Test infrastructure and fixtures for StellaOps projects. Provides deterministic time/random, canonical JSON assertions, snapshot testing, database fixtures, and OpenTelemetry capture.
|
||||
Testing infrastructure for StellaOps - deterministic helpers, fixtures, and assertions.
|
||||
|
||||
## Features
|
||||
## Quick Start
|
||||
|
||||
### Deterministic Time
|
||||
```csharp
|
||||
using StellaOps.TestKit.Time;
|
||||
|
||||
// Create a clock at a fixed time
|
||||
var clock = new DeterministicClock();
|
||||
var now = clock.UtcNow; // 2025-01-01T00:00:00Z
|
||||
|
||||
// Advance time
|
||||
clock.Advance(TimeSpan.FromMinutes(5));
|
||||
|
||||
// Or use helpers
|
||||
var clock2 = DeterministicClockExtensions.AtTestEpoch();
|
||||
var clock3 = DeterministicClockExtensions.At("2025-06-15T10:30:00Z");
|
||||
```
|
||||
|
||||
### Deterministic Random
|
||||
```csharp
|
||||
using StellaOps.TestKit.Random;
|
||||
|
||||
// Create deterministic RNG with standard test seed (42)
|
||||
var rng = DeterministicRandomExtensions.WithTestSeed();
|
||||
|
||||
// Generate reproducible values
|
||||
var number = rng.Next(1, 100);
|
||||
var text = rng.NextString(10);
|
||||
var item = rng.PickOne(new[] { "a", "b", "c" });
|
||||
```
|
||||
|
||||
### Canonical JSON Assertions
|
||||
```csharp
|
||||
using StellaOps.TestKit.Json;
|
||||
|
||||
// Assert JSON equality (ignores formatting)
|
||||
CanonicalJsonAssert.Equal(expectedJson, actualJson);
|
||||
|
||||
// Assert object equivalence
|
||||
CanonicalJsonAssert.EquivalentObjects(expectedObj, actualObj);
|
||||
|
||||
// Hash-based regression testing
|
||||
var hash = CanonicalJsonAssert.ComputeHash(json);
|
||||
CanonicalJsonAssert.MatchesHash("abc123...", json);
|
||||
using var time = new DeterministicTime(new DateTime(2026, 1, 15, 10, 30, 0, DateTimeKind.Utc));
|
||||
var timestamp = time.UtcNow; // Always 2026-01-15T10:30:00Z
|
||||
```
|
||||
|
||||
### Snapshot Testing
|
||||
```csharp
|
||||
using StellaOps.TestKit.Snapshots;
|
||||
|
||||
public class MyTests
|
||||
{
|
||||
[Fact]
|
||||
public void TestOutput()
|
||||
{
|
||||
var output = GenerateSomeOutput();
|
||||
|
||||
// Compare against __snapshots__/test_output.txt
|
||||
var snapshotPath = SnapshotHelper.GetSnapshotPath("test_output");
|
||||
SnapshotHelper.VerifySnapshot(output, snapshotPath);
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void TestJsonOutput()
|
||||
{
|
||||
var obj = new { Name = "test", Value = 42 };
|
||||
|
||||
// Compare JSON serialization
|
||||
var snapshotPath = SnapshotHelper.GetSnapshotPath("test_json", ".json");
|
||||
SnapshotHelper.VerifyJsonSnapshot(obj, snapshotPath);
|
||||
}
|
||||
}
|
||||
|
||||
// Update snapshots: set environment variable UPDATE_SNAPSHOTS=1
|
||||
SnapshotAssert.MatchesSnapshot(sbom, "TestSbom");
|
||||
// Update: UPDATE_SNAPSHOTS=1 dotnet test
|
||||
```
|
||||
|
||||
### PostgreSQL Fixture
|
||||
### PostgreSQL Integration
|
||||
```csharp
|
||||
using StellaOps.TestKit.Fixtures;
|
||||
using Xunit;
|
||||
|
||||
[Collection("Postgres")]
|
||||
public class DatabaseTests
|
||||
public class Tests : IClassFixture<PostgresFixture>
|
||||
{
|
||||
private readonly PostgresFixture _postgres;
|
||||
|
||||
public DatabaseTests(PostgresFixture postgres)
|
||||
{
|
||||
_postgres = postgres;
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public async Task TestQuery()
|
||||
{
|
||||
// Use connection string
|
||||
await using var conn = new Npgsql.NpgsqlConnection(_postgres.ConnectionString);
|
||||
await conn.OpenAsync();
|
||||
|
||||
// Execute SQL
|
||||
await _postgres.ExecuteSqlAsync("CREATE TABLE test (id INT)");
|
||||
|
||||
// Create additional databases
|
||||
await _postgres.CreateDatabaseAsync("otherdb");
|
||||
}
|
||||
public async Task TestDb() { /* use _fixture.ConnectionString */ }
|
||||
}
|
||||
```
|
||||
|
||||
### Valkey/Redis Fixture
|
||||
```csharp
|
||||
using StellaOps.TestKit.Fixtures;
|
||||
using Xunit;
|
||||
|
||||
[Collection("Valkey")]
|
||||
public class CacheTests
|
||||
{
|
||||
private readonly ValkeyFixture _valkey;
|
||||
|
||||
public CacheTests(ValkeyFixture valkey)
|
||||
{
|
||||
_valkey = valkey;
|
||||
}
|
||||
|
||||
[Fact]
|
||||
public void TestCache()
|
||||
{
|
||||
var connectionString = _valkey.ConnectionString;
|
||||
// Use with your Redis/Valkey client
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### OpenTelemetry Capture
|
||||
```csharp
|
||||
using StellaOps.TestKit.Telemetry;
|
||||
|
||||
[Fact]
|
||||
public void TestTracing()
|
||||
{
|
||||
using var otel = new OTelCapture("my-service");
|
||||
|
||||
// Code that emits traces
|
||||
using (var activity = otel.ActivitySource.StartActivity("operation"))
|
||||
{
|
||||
activity?.SetTag("key", "value");
|
||||
}
|
||||
|
||||
// Assert traces
|
||||
otel.AssertActivityExists("operation");
|
||||
otel.AssertActivityHasTag("operation", "key", "value");
|
||||
|
||||
// Get summary for debugging
|
||||
Console.WriteLine(otel.GetTraceSummary());
|
||||
}
|
||||
```
|
||||
|
||||
## Usage in Tests
|
||||
|
||||
Add to your test project:
|
||||
```xml
|
||||
<ItemGroup>
|
||||
<ProjectReference Include="..\..\__Libraries\StellaOps.TestKit\StellaOps.TestKit.csproj" />
|
||||
</ItemGroup>
|
||||
```
|
||||
|
||||
## Design Principles
|
||||
|
||||
- **Determinism**: All utilities produce reproducible results
|
||||
- **Offline-first**: No network dependencies (uses Testcontainers for local infrastructure)
|
||||
- **Minimal dependencies**: Only essential packages
|
||||
- **xUnit-friendly**: Works seamlessly with xUnit fixtures and collections
|
||||
