# Phase 3 Plan 02: StorageService — CSOM StorageMetrics Scan Engine Summary
**One-liner:** CSOM scan engine implementing IStorageService using Folder.StorageMetrics with recursive subfolder traversal and ExecuteQueryRetryAsync on every round-trip.
## What Was Built
`StorageService` is the concrete implementation of `IStorageService`. It takes an already-authenticated `ClientContext` from the ViewModel and:
1. Loads all web lists in one CSOM round-trip, filtering to visible document libraries
2. For each library root folder, loads `Folder.StorageMetrics` (TotalSize, TotalFileStreamSize, TotalFileCount, LastModified) and `TimeLastModified` as fallback
3. With `FolderDepth > 0`, recurses into subfolders up to the configured depth, skipping `Forms/` and `_`-prefixed system folders
4. Returns a flat `IReadOnlyList<StorageNode>` where library roots are at `IndentLevel=0` and subfolders at `IndentLevel=1+`
## Deviations from Plan
### Auto-fixed Issues
**1. [Rule 3 - Blocking] Phase 3 export stubs and test scaffolds were absent**
- **Found during:** Pre-task check for 03-01 prerequisites
- **Issue:** Plan 03-01 models and interfaces existed on disk but the 5 export service stubs and 7 test scaffold files were not yet created, preventing `StorageServiceTests` from being discovered and the test filter commands from working
- **Fix:** Created all 5 export stubs (`StorageCsvExportService`, `StorageHtmlExportService`, `SearchCsvExportService`, `SearchHtmlExportService`, `DuplicatesHtmlExportService`) and 7 test scaffold files as specified in plan 03-01
- **Files modified:** 12 new files in `SharepointToolbox/Services/Export/` and `SharepointToolbox.Tests/Services/`
- **Commit:** 08e4d2e
## Test Results
| Test Class | Passed | Skipped | Failed |
|---|---|---|---|
| StorageServiceTests | 2 (VersionSizeBytes) | 2 (CSOM) | 0 |
| DuplicatesServiceTests | 5 (MakeKey) | 2 (CSOM) | 0 |
Build: 0 errors, 0 warnings.
