# Evidence Re-Index Tooling (CLI)

## Module
EvidenceLocker

## Status
IMPLEMENTED

## Description
CLI commands for evidence store maintenance including reindexing (`stella evidence reindex`), chain-of-custody verification (`stella evidence verify-continuity`), and evidence migration between storage backends.

## Implementation Details
- **Modules**: `src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Reindexing/`, `src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Core/Reindexing/`
- **Key Classes**:
  - `EvidenceReindexService` (`src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Reindexing/EvidenceReindexService.cs`) - rebuilds evidence indexes from object store contents
  - `EvidenceBundleRepository` (`src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Repositories/EvidenceBundleRepository.cs`) - repository layer for re-indexed bundles
  - `StorageKeyGenerator` (`src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Storage/StorageKeyGenerator.cs`) - generates consistent storage keys for evidence items
  - `FileSystemEvidenceObjectStore` (`src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Storage/FileSystemEvidenceObjectStore.cs`) - filesystem storage backend
  - `S3EvidenceObjectStore` (`src/EvidenceLocker/StellaOps.EvidenceLocker/StellaOps.EvidenceLocker.Infrastructure/Storage/S3EvidenceObjectStore.cs`) - S3 storage backend for migration
- **Interfaces**: `IEvidenceReindexService`
- **Source**: SPRINT_20260112_018_EVIDENCE_reindex_tooling.md

## E2E Test Plan
- [ ] Run `EvidenceReindexService` and verify it rebuilds the evidence index from object store contents
- [ ] Verify reindexing preserves all evidence bundle metadata and content-addressed IDs
- [ ] Verify chain-of-custody verification detects a gap in the evidence timeline
- [ ] Migrate evidence from `FileSystemEvidenceObjectStore` to `S3EvidenceObjectStore` and verify all bundles are accessible
- [ ] Verify `StorageKeyGenerator` produces consistent keys before and after reindexing
- [ ] Verify reindexing handles corrupt or missing files gracefully with error reporting
