UI work to fill SBOM sourcing management gap. UI planning remaining functionality exposure. Work on CI/Tests stabilization

Introduces CGS determinism test runs to CI workflows for Windows, macOS, Linux, Alpine, and Debian, fulfilling CGS-008 cross-platform requirements. Updates local-ci scripts to support new smoke steps, test timeouts, progress intervals, and project slicing for improved test isolation and diagnostics.

# E2E Replayable Verdict Tests
Sprint: `SPRINT_20251229_004_005_E2E`
## Overview
End-to-end tests validating the complete reproducible verdict pipeline:
```
Image → Scanner → Feedser → VexLens → Verdict Builder → DSSE Signing → UI Delta View
```
With capture of artifacts bundle enabling byte-for-byte replay.
## Test Structure
### Golden Bundles
Located in `src/__Tests/fixtures/e2e/bundle-XXXX/`:
```
bundle-0001/
├── manifest.json # ReplayManifest v2
├── inputs/
│ ├── sbom.cdx.json # Canonical SBOM
│ ├── feeds/
│ │ └── osv-snapshot.json # Pinned feed subset
│ ├── vex/
│ │ └── vendor.openvex.json
│ └── policy/
│ └── rules.yaml
├── outputs/
│ ├── verdict.json # Expected verdict
│ └── verdict.dsse.json # DSSE envelope (when signing enabled)
├── attestation/
│ ├── test-keypair.pem # Test signing key
│ └── public-key.pem
└── meta.json # Bundle metadata
```
### Test Categories
| Test | Status | Purpose |
|------|--------|---------|
| E2E-001 | ✅ DONE | Golden bundle creation and loading |
| E2E-002 | ⏳ SKIPPED | Full pipeline test (requires service integration) |
| E2E-003 | ⏳ SKIPPED | Replay verification test |
| E2E-004 | ⏳ SKIPPED | Delta verdict test |
| E2E-005 | ⏳ SKIPPED | DSSE signature verification |
| E2E-006 | ⏳ SKIPPED | Offline/air-gap replay test |
| E2E-007 | ✅ DONE | CLI `stella verify --bundle` command |
| E2E-008 | ⏳ SKIPPED | Cross-platform replay test |
## Running Tests
### All E2E Tests
```bash
dotnet test src/__Tests/E2E/ReplayableVerdict/ \
--filter "Category=E2E"
```
### Determinism Tests Only
```bash
dotnet test src/__Tests/E2E/ReplayableVerdict/ \
--filter "Category=Determinism"
```
### Individual Test
```bash
dotnet test src/__Tests/E2E/ReplayableVerdict/ \
--filter "FullyQualifiedName~Bundle_LoadsSuccessfully"
```
## Current Status
### ✅ Completed
- Golden bundle structure created (`bundle-0001`)
- Minimal test inputs:
- SBOM: Alpine 3.19 with 5 packages
- Feeds: 2 synthetic OSV advisories
- VEX: 1 OpenVEX statement
- Policy: Basic rules with scoring
- Manifest schema (ReplayManifest v2)
- Bundle loader implementation
- 8 test cases defined (3 passing, 5 skipped pending integration)
### ⏳ Pending Integration
The following tests are **skipped** pending service integration:
1. **Full Pipeline Test (E2E-002)**
- Requires: Scanner, VexLens, VerdictBuilder services
- Blocks: End-to-end verdict generation
2. **Replay Verification (E2E-003)**
- Requires: VerdictBuilder.ReplayAsync()
- Blocks: Determinism validation
3. **Delta Verdict (E2E-004)**
- Requires: VerdictBuilder.DiffAsync() + bundle-0002
- Blocks: Version comparison testing
4. **DSSE Signing (E2E-005)**
- Requires: Signer service integration
- Blocks: Attestation verification
5. **Offline Replay (E2E-006)**
- Requires: Network isolation test infrastructure
- Blocks: Air-gap validation
6. **Cross-Platform (E2E-008)**
- Requires: Multi-platform CI runners
- Blocks: Platform-independent determinism
### ✅ Completed: E2E-007 CLI Verify Command
**Implementation:**
The `stella verify bundle` command has been implemented in:
- `src/Cli/StellaOps.Cli/Commands/CommandHandlers.VerifyBundle.cs` (handler)
- `src/Cli/StellaOps.Cli/Commands/VerifyCommandGroup.cs` (command registration)
- `src/Cli/__Tests/StellaOps.Cli.Tests/Commands/VerifyBundleCommandTests.cs` (tests)
**Usage:**
```bash
stella verify bundle --bundle <path-to-bundle-directory>
stella verify bundle --bundle <path-to-bundle.tar.gz> # Not yet supported
stella verify bundle --bundle ./bundle-0001 --skip-replay # Skip verdict replay
stella verify bundle --bundle ./bundle-0001 --output json # JSON output
```
**Features:**
1. ✅ Loads bundle manifest
2. ✅ Validates input hashes (SBOM, feeds, VEX, policy)
3. ⏳ Replays verdict (stubbed - requires VerdictBuilder integration)
4. ✅ Compares to expected hash
5. ⏳ Verifies DSSE signature (stubbed - requires Signer integration)
6. ✅ Outputs PASS/FAIL with violations
**Exit Codes:**
- `0` - PASS: All validations passed
- `7` - File not found (bundle or manifest)
- `8` - FAIL: Validation violations detected
- `9` - Not implemented (tar.gz extraction)
## Integration Roadmap
### Phase 1: Service Integration (Week 1-2)
1. Integrate Scanner service
2. Integrate VexLens consensus
3. Integrate VerdictBuilder
4. Enable E2E-002 (Full Pipeline)
### Phase 2: Replay Functionality (Week 3)
1. Implement VerdictBuilder.ReplayAsync()
2. Enable E2E-003 (Replay Verification)
3. Create bundle-0002 for delta testing
4. Enable E2E-004 (Delta Verdict)
### Phase 3: Signing & Attestation (Week 4)
1. Integrate Signer service
2. Generate test keypair
3. Enable E2E-005 (DSSE Signing)
4. Implement CLI verify command (E2E-007)
### Phase 4: Advanced Validation (Week 5)
1. Setup network isolation for E2E-006
2. Configure multi-platform CI for E2E-008
3. Add performance benchmarks
4. Add chaos testing variants
## Bundle Management
### Creating a New Bundle
```bash
# 1. Create bundle directory
mkdir -p src/__Tests/fixtures/e2e/bundle-XXXX
# 2. Use Fixture Harvester
cd src/__Tests/Tools/FixtureHarvester
dotnet run harvest --type e2e --id bundle-XXXX
# 3. Add inputs (SBOM, feeds, VEX, policy)
# Place files in bundle-XXXX/inputs/
# 4. Run pipeline to generate outputs
stella scan --record --bundle bundle-XXXX
# 5. Compute hashes and update manifest
dotnet run validate --bundle bundle-XXXX
# 6. Freeze bundle (commit to git)
git add src/__Tests/fixtures/e2e/bundle-XXXX
git commit -m "Add E2E bundle: bundle-XXXX"
```
### Validating Bundles
```bash
# Validate all bundles
dotnet run --project src/__Tests/Tools/FixtureHarvester \
validate --path src/__Tests/fixtures/e2e
# CI validation
.gitea/workflows/e2e-replay.yml
```
## Determinism Guarantees
### Input Stability
- All inputs pinned with SHA-256 hashes
- Feed snapshots frozen at capture time
- Policy files versioned
- SBOM canonical format (sorted, normalized)
### Output Reproducibility
- Verdict hash computed from canonical JSON
- UTC timestamps in ISO-8601 format
- Stable sorting (CVEs, packages, findings)
- No system-specific paths or UUIDs
### Cross-Platform Compatibility
- Tests run on: Ubuntu 22.04, Alpine 3.19, Debian Bookworm
- Verdict hash must match across all platforms
- File path normalization (forward slashes)
- Line ending normalization (LF only)
## Troubleshooting
### Bundle Load Failures
```bash
# Check manifest syntax
cat src/__Tests/fixtures/e2e/bundle-0001/manifest.json | jq .
# Verify file paths
ls src/__Tests/fixtures/e2e/bundle-0001/inputs/
# Validate hashes
sha256sum src/__Tests/fixtures/e2e/bundle-0001/inputs/sbom.cdx.json
```
### Hash Mismatches
```bash
# Recompute hashes
dotnet run --project src/__Tests/Tools/FixtureHarvester \
validate --path src/__Tests/fixtures/e2e
# Compare expected vs actual
diff -u expected.json actual.json | jq .
```
### Skipped Tests
Skipped tests indicate missing service integration. Follow integration roadmap to enable.
