Phase 03 Plan 05: Search and Duplicate Export Services Summary

SearchCsvExportService (UTF-8 BOM CSV), SearchHtmlExportService (sortable/filterable HTML), and DuplicatesHtmlExportService (grouped card HTML) — all 9 export tests pass

Performance

• Duration: 4 min
• Started: 2026-04-02T13:34:47Z
• Completed: 2026-04-02T13:38:47Z
• Tasks: 2
• Files modified: 3

Accomplishments

• SearchCsvExportService: UTF-8 BOM CSV with proper 8-column header and RFC 4180 CSV escaping
• SearchHtmlExportService: self-contained HTML with click-to-sort columns and live filter input, ported from PS Export-SearchToHTML
• DuplicatesHtmlExportService: collapsible group cards with item count badges and path tables, ported from PS Export-DuplicatesToHTML

Task Commits

Each task was committed atomically:

1. Task 1: SearchCsvExportService + SearchHtmlExportService - e174a18 (feat, part of 03-07 session)
2. Task 2: DuplicatesHtmlExportService - fc1ba00 (feat)

Plan metadata: (see final docs commit)

Files Created/Modified

• SharepointToolbox/Services/Export/SearchCsvExportService.cs - UTF-8 BOM CSV exporter for SearchResult list (SRCH-03)
• SharepointToolbox/Services/Export/SearchHtmlExportService.cs - Sortable/filterable HTML exporter for SearchResult list (SRCH-04)
• SharepointToolbox/Services/Export/DuplicatesHtmlExportService.cs - Grouped card HTML exporter for DuplicateGroup list (DUPL-03)

Decisions Made

• SearchCsvExportService uses UTF8Encoding(encoderShouldEmitUTF8Identifier: true) for Excel compatibility — consistent with Phase 2 CsvExportService pattern
• Result count in SearchHtmlExportService is rendered as a C# interpolated string at generation time rather than a JS variable — avoids conflict between C# $$""" interpolation and JS template literal syntax
• DuplicatesHtmlExportService uses badge-dup (red) for all groups — DUPL-03 requires showing copies count; ok/diff distinction was removed from final spec

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Fixed implicit File class resolution in WPF project

• Found during: Task 1 (SearchCsvExportService and SearchHtmlExportService)
• Issue: File.WriteAllTextAsync fails to compile — WPF project does not include System.IO in implicit usings (established project pattern documented in STATE.md decisions)
• Fix: Changed File.WriteAllTextAsync to System.IO.File.WriteAllTextAsync in both services
• Files modified: SearchCsvExportService.cs, SearchHtmlExportService.cs
• Verification: Test project builds successfully; 6/6 SearchExportServiceTests pass
• Committed in: e174a18 (Task 1 commit, part of 03-07 session)

---

Total deviations: 1 auto-fixed (Rule 1 — known WPF project pattern) Impact on plan: Necessary correctness fix. No scope creep.

Issues Encountered

• Task 1 (SearchCsvExportService + SearchHtmlExportService) was already committed in the prior feat(03-07) session — the plan was executed out of order. Task 2 (DuplicatesHtmlExportService) was the only remaining work in this session.
• WPF temp project (_wpftmp.csproj) showed pre-existing errors for StorageView and ClientRuntimeContext.Url during build attempts — these are pre-existing blockers from plan 03-07 state (StorageView untracked, not in scope for this plan). Used dotnet build SharepointToolbox.Tests/ directly to avoid them.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• All 3 export services are fully implemented and tested (9/9 tests pass)
• SearchViewModel and DuplicatesViewModel (plan 03-08) can now wire export commands to these services
• StorageView.xaml is untracked (created in 03-07 session) — needs to be committed before plan 03-08 runs
