   • Added BuildVerifyBundleCommand() method

4. CliExitCodes.cs (updated)

   • FileNotFound = 7
   • GeneralError = 8
   • NotImplemented = 9

CLI Usage

# Basic verification
stella verify bundle --bundle ./bundle-0001

# Skip verdict replay (hash validation only)
stella verify bundle --bundle ./bundle-0001 --skip-replay

# JSON output for CI/CD
stella verify bundle --bundle ./bundle-0001 --output json

# Exit codes:
# 0 = PASS
# 7 = File not found
# 8 = Validation failed
# 9 = Not implemented (tar.gz)

Features Implemented

• ✅ Loads bundle manifest
• ✅ Validates all input file hashes (SBOM, feeds, VEX, policy)
• ✅ Computes directory hashes (sorted file concatenation)
• ⏳ Replays verdict (stubbed - VerdictBuilder integration pending)
• ⏳ Verifies DSSE signatures (stubbed - Signer integration pending)
• ✅ Reports violations with clear messages
• ✅ Outputs PASS/FAIL with exit codes

Integration Points (Pending)

• VerdictBuilder service (for verdict replay)
• Signer service (for DSSE signature verification)
• Tar.gz extraction (requires System.Formats.Tar)

Technical Highlights

SOLID Principles Applied

• Single Responsibility: Each component focused on one task
• Open/Closed: Extensible via configuration and plugin system
• Liskov Substitution: Reuses DebianVersionComparer interface
• Interface Segregation: Minimal coupling, clear interfaces
• Dependency Injection: Service provider pattern throughout

Determinism Guarantees

• SHA-256 hash pinning for all inputs
• Stable sorting (file path order)
• UTC ISO-8601 timestamps
• Canonical JSON serialization
• No system-specific paths or UUIDs

Code Quality

• Comprehensive XML documentation
• Copyright headers on all files
• Sprint references in file headers
• Clear error messages
• Input validation at boundaries

Next Steps

Immediate (Next Sprint)

1. Implement OVAL XML Parser (ASTRA-004)

   • Create OVAL schema models
   • Parse XML using System.Xml.Linq
   • Extract vulnerability definitions
   • Test with real Astra OVAL samples

2. Implement DTO to Advisory Mapping (ASTRA-008)

   • Map OVAL definitions to Advisory model
   • Apply trust vectors
   • Generate provenance metadata

3. Add Integration Tests (ASTRA-010)

   • Mock OVAL XML responses
   • Golden file validation
   • Version comparison edge cases

Future

• E2E Service Integration - Wire VerdictBuilder and Signer
• Cross-Platform CI - Ubuntu/Alpine/Debian runners
• Performance - OVAL parsing benchmarks
• Bundle Variants - Create test bundles for different scenarios
