# Sprint 20251229_004_E2E_replayable_verdict <20> Replayable Verdict E2E
## Topic & Scope
- Build end-to-end replayable verdict tests that validate deterministic scanning and DSSE attestation flows.
- Capture golden bundles for repeatable replay and drift detection validation.
- Extend CLI verification to consume bundles in offline mode.
- **Working directory:** src/__Tests/E2E. Evidence: E2E test suite, golden bundle fixtures, and CLI verification updates.
## Dependencies & Concurrency
- Depends on ReplayManifest v2 schema, EvidenceLocker bundles, and Signer integration.
- Some tasks remain blocked until VerdictBuilder replay/diff APIs are finalized.
## Documentation Prerequisites
- docs/modules/replay/architecture.md
- docs/replay/DETERMINISTIC_REPLAY.md
- docs/modules/scanner/architecture.md
## Delivery Tracker
| # | Task ID | Status | Key dependency / next step | Owners | Task Definition |
| --- | --- | --- | --- | --- | --- |
| 1 | E2E-001 | DONE | Fixture harness | QA <20> E2E | Create golden bundle fixture with minimal SBOM, advisories, VEX, policy. |
| 2 | E2E-002 | BLOCKED | Pipeline integration | QA <20> E2E | Implement full pipeline E2E test across Scanner/VexLens/VerdictBuilder. |
| 3 | E2E-003 | BLOCKED | Verdict replay API | QA <20> E2E | Implement replay verification test using VerdictBuilder.ReplayAsync. |
| 4 | E2E-004 | BLOCKED | Verdict diff API | QA <20> E2E | Implement delta verdict test using VerdictBuilder.DiffAsync. |
| 5 | E2E-005 | BLOCKED | Signer service | QA <20> E2E | Implement DSSE signature verification in E2E harness. |
| 6 | E2E-006 | BLOCKED | Offline harness | QA <20> E2E | Implement air-gap replay test infrastructure. |
| 7 | E2E-007 | DONE | CLI verification | QA <20> CLI | Add stella verify --bundle command with hash validation. |
| 8 | E2E-008 | BLOCKED | CI runners | QA <20> E2E | Add cross-platform replay test in CI. |
## Execution Log
| Date (UTC) | Update | Owner |
| --- | --- | --- |
| 2025-12-29 | Sprint renamed to SPRINT_20251229_004_E2E_replayable_verdict.md and normalized to standard template; legacy content retained in appendix. | Planning |
## Decisions & Risks
- Risk: blocked E2E tasks delay replay validation; mitigation is to stage mocks until VerdictBuilder APIs land.
- Risk: offline replay is hard to emulate in CI; mitigation is a dedicated air-gap harness.
## Next Checkpoints
- TBD: VerdictBuilder replay/diff API readiness review.

## Sprint Overview
| Field | Value |
|-------|-------|
| **IMPLID** | 20251229 |
| **BATCHID** | 004 |
| **MODULEID** | E2E |
| **Topic** | End-to-End Replayable Verdict Tests |
| **Working Directory** | `src/__Tests/E2E/` |
| **Status** | DONE (partial - foundation complete, service integration pending) |
## Context
The advisory proposes a scripted E2E path:
```
image → Scanner → Feedser → VexLens → signed verdict (DSSE) → UI delta view
```
With capture of an artifacts bundle enabling byte-for-byte replay.
Existing infrastructure:
- `ReplayManifest` v2 schema exists
- Scanner `RecordModeService` captures replay bundles
- `PolicySimulationInputLock` for pinning
- EvidenceLocker with Merkle tree builder
Gap: No E2E test that validates the full pipeline with replay verification.
## Related Documentation
- `docs/modules/replay/architecture.md`
- `docs/replay/DETERMINISTIC_REPLAY.md`
- `docs/modules/scanner/architecture.md` (Appendix A.0 - Replay/Record mode)
- Sprint `SPRINT_20251229_001_001_BE_cgs_infrastructure`
## Prerequisites
- [ ] Read ReplayManifest v2 schema
- [ ] Understand Scanner RecordModeService
- [ ] Review EvidenceLocker bundle format

- Deliver parsing, normalization, and AOC-compliant mapping into observations and linksets.
- Provide integration tests and documentation updates for the new connector.
- **Working directory:** src/Concelier. Evidence: connector project, tests, and architecture doc update.
## Dependencies & Concurrency
- Depends on confirmed Astra advisory feed format and AOC guardrails.
- Can run in parallel with other Concelier connector work if shared normalization stays stable.
## Documentation Prerequisites
- docs/modules/concelier/architecture.md
- docs/modules/platform/architecture-overview.md
- docs/modules/airgap/architecture.md

## Decisions & Risks
- ✅ RESOLVED: feed format uncertainty - OVAL XML format confirmed via research (2025-12-29)
- Risk: AOC guardrail violations; mitigate by aligning with existing connector patterns.
- ✅ RESOLVED: Authentication not required - public OVAL repositories (2025-12-29)
- ✅ RESOLVED: Version comparison uses existing DebianVersionComparer (2025-12-29)
## Next Checkpoints
- TBD: Astra feed format confirmation.

## Context
This sprint implements the Astra Linux advisory connector - the **only major gap** identified in the cross-distro vulnerability intelligence analysis. All other distro connectors (RedHat, SUSE, Ubuntu, Debian, Alpine) are already implemented.
**Gap Analysis Summary:**
- RedHat CSAF connector: ✅ 100% complete
- SUSE CSAF connector: ✅ 100% complete
- Ubuntu USN connector: ✅ 100% complete
- Debian DSA connector: ✅ 100% complete
- Alpine SecDB connector: ✅ 100% complete
- **Astra Linux connector: ❌ 0% (this sprint)**
**Astra Linux Context:**
- Russian domestic Linux distribution based on Debian
- FSTEC certified (Russian security certification)
- Advisory source: `https://astra.group/security/` or equivalent CSAF endpoint
- Version comparator: Uses dpkg EVR (inherits from Debian)
- Target markets: Russian government, defense, critical infrastructure
## Related Documentation
- `docs/modules/concelier/architecture.md`
- `src/Concelier/__Connectors/StellaOps.Concelier.Connector.Debian/` (base pattern)
- `src/Concelier/__Connectors/StellaOps.Concelier.Connector.RedHat/` (CSAF pattern)
- Existing version comparator: `src/__Libraries/StellaOps.VersionComparison/Comparers/DebianVersionComparer.cs`
## Prerequisites
- [ ] Identify Astra Linux official advisory feed URL/format
- [ ] Confirm whether Astra uses CSAF 2.0 or custom format
- [ ] Review Debian connector implementation patterns
- [ ] Understand AOC (Aggregation-Only Contract) constraints

### Interface Implementation
```csharp
// Location: src/Concelier/__Connectors/StellaOps.Concelier.Connector.Astra/AstraAdvisorySource.cs
public sealed class AstraAdvisorySource : IAdvisorySource
{
public string SourceId => "astra";
public string DisplayName => "Astra Linux Security";
public DistroFamily DistroFamily => DistroFamily.Debian; // Based on Debian
private readonly IAstraClient _client;
private readonly AstraAdvisoryParser _parser;
private readonly ILogger<AstraAdvisorySource> _logger;
public async IAsyncEnumerable<AdvisoryObservation> FetchAsync(
FetchOptions options,
[EnumeratorCancellation] CancellationToken ct)
{
// Fetch from Astra advisory endpoint
var advisories = await _client.GetAdvisoriesAsync(options.Since, ct);
foreach (var advisory in advisories)
{
ct.ThrowIfCancellationRequested();
var parsed = _parser.Parse(advisory);
foreach (var observation in MapToObservations(parsed))
{
yield return observation;
}
}
}
public async ValueTask<AdvisoryObservation?> GetByIdAsync(
string advisoryId,
CancellationToken ct)
{
var advisory = await _client.GetAdvisoryAsync(advisoryId, ct);
if (advisory == null) return null;
var parsed = _parser.Parse(advisory);
return MapToObservations(parsed).FirstOrDefault();
}
private IEnumerable<AdvisoryObservation> MapToObservations(AstraAdvisory advisory)
{
foreach (var cve in advisory.Cves)
{
foreach (var pkg in advisory.AffectedPackages)
{
yield return new AdvisoryObservation
{
SourceId = SourceId,
AdvisoryId = advisory.Id,
Cve = cve,
PackageName = _normalizer.Normalize(pkg.Name),
AffectedVersions = pkg.AffectedVersions,
FixedVersion = pkg.FixedVersion,
Severity = advisory.Severity,
TrustVector = _trustConfig.DefaultVector,
ObservedAt = DateTimeOffset.UtcNow,
RawPayload = advisory.RawJson
};
}
}
}
}
```
### Version Matcher (Debian EVR Inheritance)
```csharp
// Location: src/Concelier/__Connectors/StellaOps.Concelier.Connector.Astra/AstraVersionMatcher.cs
public sealed class AstraVersionMatcher : IVersionMatcher
{
private readonly DebianVersionComparer _debianComparer;
public AstraVersionMatcher()
{
// Astra uses dpkg EVR format (epoch:version-release)
_debianComparer = new DebianVersionComparer();
}
public bool IsAffected(string installedVersion, VersionConstraint constraint)
{
// Delegate to Debian EVR comparison
return constraint.Type switch
{
ConstraintType.LessThan =>
_debianComparer.Compare(installedVersion, constraint.Version) < 0,
ConstraintType.LessThanOrEqual =>
_debianComparer.Compare(installedVersion, constraint.Version) <= 0,
ConstraintType.Equal =>
_debianComparer.Compare(installedVersion, constraint.Version) == 0,
ConstraintType.Range =>
IsInRange(installedVersion, constraint),
_ => false
};
}
public bool IsFixed(string installedVersion, string? fixedVersion)
{
if (fixedVersion == null) return false;
return _debianComparer.Compare(installedVersion, fixedVersion) >= 0;
}
}
```
### Trust Configuration
```csharp
// Location: src/Concelier/__Connectors/StellaOps.Concelier.Connector.Astra/AstraTrustConfig.cs
public sealed class AstraTrustConfig
{
// Tier 1 - Official distro advisory source
public TrustVector DefaultVector => new(
Provenance: 0.95m, // Official FSTEC-certified source
Coverage: 0.90m, // Comprehensive for Astra packages
Replayability: 0.85m // Deterministic advisory format
);
public static readonly TrustVector MinimumAcceptable = new(
Provenance: 0.70m,
Coverage: 0.60m,
Replayability: 0.50m
);
}
```
### Connector Configuration
```yaml
# etc/connectors/astra.yaml
connector:
id: astra
display_name: Astra Linux Security
enabled: true
source:
base_url: https://astra.group/security/csaf/ # Or actual endpoint
format: csaf # or custom
auth:
type: none # or api_key if required
rate_limit:
requests_per_minute: 60
trust:
provenance: 0.95
coverage: 0.90
replayability: 0.85
offline:
bundle_path: /var/lib/stellaops/feeds/astra/
update_frequency: daily
```
