Phase 03 Plan 03: Storage Export Services — CSV and Collapsible-Tree HTML Summary

StorageCsvExportService (UTF-8 BOM flat CSV) and StorageHtmlExportService (self-contained collapsible-tree HTML) replace stubs — 6 tests pass

Performance

• Duration: 2 min
• Started: 2026-04-02T13:29:04Z
• Completed: 2026-04-02T13:30:43Z
• Tasks: 2
• Files modified: 2

Accomplishments

• StorageCsvExportService.BuildCsv produces UTF-8 BOM CSV with header row: Library, Site, Files, Total Size (MB), Version Size (MB), Last Modified using RFC 4180 quoting
• StorageHtmlExportService.BuildHtml produces self-contained HTML with inline CSS/JS, toggle(i) function, and collapsible subfolder rows (sf-{i} IDs), ported from PS Export-StorageToHTML
• All 6 tests pass (3 CSV + 3 HTML)

Task Commits

1. Task 1: Implement StorageCsvExportService - 94ff181 (feat)
2. Task 2: Implement StorageHtmlExportService - eafaa15 (feat)

Files Created/Modified

• SharepointToolbox/Services/Export/StorageCsvExportService.cs - Full BuildCsv implementation replacing string.Empty stub
• SharepointToolbox/Services/Export/StorageHtmlExportService.cs - Full BuildHtml implementation with collapsible tree rendering

Decisions Made

• Explicit System.IO using added to both files — WPF project does not include System.IO in implicit usings; this is an established project pattern from Phase 1

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Added explicit System.IO using to StorageCsvExportService

• Found during: Task 1 (StorageCsvExportService implementation)
• Issue: CS0103 — File not found; WPF project lacks System.IO in implicit usings
• Fix: Added using System.IO; at top of file
• Files modified: SharepointToolbox/Services/Export/StorageCsvExportService.cs
• Verification: Build succeeded, 3 CSV tests pass
• Committed in: 94ff181 (Task 1 commit)

2. [Rule 3 - Blocking] Added explicit System.IO using to StorageHtmlExportService

• Found during: Task 2 (StorageHtmlExportService implementation)
• Issue: Same CS0103 pattern — File.WriteAllTextAsync requires System.IO
• Fix: Added using System.IO; preemptively before compilation
• Files modified: SharepointToolbox/Services/Export/StorageHtmlExportService.cs
• Verification: Build succeeded, 3 HTML tests pass
• Committed in: eafaa15 (Task 2 commit)

---

Total deviations: 2 auto-fixed (2 blocking — same root cause: WPF project implicit usings) Impact on plan: Both fixes necessary for compilation. No scope creep. Consistent with established project pattern.

Issues Encountered

The -x flag passed in the plan's dotnet test command is not a valid MSBuild switch. Omitting it works correctly — documented for future plans.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• StorageCsvExportService and StorageHtmlExportService ready for use by StorageViewModel (Plan 03-07)
• Both services have WriteAsync variants for file-system output
• No blockers for Wave 2 parallel execution (03-04, 03-06 can proceed independently)

Self-Check: PASSED

All files and commits verified present.
