# Scanner Integration for Binary Analysis

## Module
BinaryIndex

## Status
IMPLEMENTED

## Description
Binary vulnerability analysis integrated into the scanner worker pipeline with patch verification and build provenance reproducibility verification.

## Implementation Details
- **Modules**: `src/BinaryIndex/`, `src/Scanner/`
- **Key Classes**:
  - `BinaryVulnerabilityService` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Persistence/Services/BinaryVulnerabilityService.cs`) - core binary vulnerability detection service used by scanner pipeline; queries `ICorpusQueryService` for function matches
  - `CachedBinaryVulnerabilityService` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Cache/CachedBinaryVulnerabilityService.cs`) - cached decorator with `LookupByDeltaSignatureAsync` for scanner integration
  - `ResolutionService` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Core/Resolution/ResolutionService.cs`) - resolves whether a CVE is fixed based on binary-level evidence
  - `ReproducibleBuildJob` (`src/BinaryIndex/StellaOps.BinaryIndex.Worker/Jobs/ReproducibleBuildJob.cs`) - worker job for build provenance verification
  - `EnsembleDecisionEngine` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Ensemble/EnsembleDecisionEngine.cs`) - multi-tier matching for scanner-detected vulnerabilities
- **Integration Points**: Scanner pipeline calls `IBinaryVulnerabilityService` to enrich findings with binary-level patch verification

## E2E Test Plan
- [ ] Trigger a scanner scan on a container with known binaries and verify binary analysis runs automatically
- [ ] Verify scanner findings are enriched with binary-level patch status (Fixed, Vulnerable, Unknown)
- [ ] Verify `CachedBinaryVulnerabilityService` caches scanner lookups for performance
- [ ] Verify build provenance verification runs as a background worker job
- [ ] Verify ensemble decision engine produces consistent results when called from scanner pipeline
- [ ] Verify binary analysis results are included in scanner output findings
