# Binary Proof Verification Pipeline

## Module
BinaryIndex

## Status
IMPLEMENTED

## Description
Full binary proof verification with ground truth sources (buildinfo, debuginfod, reproducible builds), validation, and golden set testing.

## Implementation Details
- **Modules**: `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.GroundTruth.Reproducible/`, `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Validation/`, `src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Validation.Abstractions/`
- **Key Classes**:
  - `ValidationHarnessService` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.GroundTruth.Reproducible/ValidationHarnessService.cs`) - orchestrates reproducible-build-based validation runs
  - `ValidationHarness` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Validation/ValidationHarness.cs`) - main validation harness with matcher adapter factory integration
  - `KpiRegressionService` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.GroundTruth.Reproducible/Services/KpiRegressionService.cs`) - KPI regression detection across validation runs
  - `GroundTruthProvenanceResolver` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.DeltaSig/Provenance/GroundTruthProvenanceResolver.cs`) - resolves symbol provenance from ground truth sources
- **Interfaces**: `IValidationHarness` (`src/BinaryIndex/__Libraries/StellaOps.BinaryIndex.Validation.Abstractions/IValidationHarness.cs`), `IKpiRegressionService`, `ISymbolProvenanceResolver`
- **Registration**: `ServiceCollectionExtensions.AddCorpusBundleExport/Import` for bundle exchange

## E2E Test Plan
- [ ] Run a validation harness against a known binary pair and verify proof correctness
- [ ] Verify ground truth resolution from buildinfo sources produces correct provenance data
- [ ] Verify KPI regression service detects accuracy drops between validation runs
- [ ] Verify golden set validation produces deterministic, reproducible results
- [ ] Verify corpus bundle export/import round-trips correctly
- [ ] Verify validation run attestor generates valid attestation predicates with corpus snapshot IDs
