+# Phase 7 Plan 06: Export Services Summary
+
+**Two self-contained export services for User Access Audit: per-user CSV files with summary headers and a single interactive HTML report with dual-view toggle (by-user/by-site), collapsible groups, sortable columns, risk highlighting, and color-coded access type badges.**
+
+## Performance
+
+- **Duration:** ~2 min
+- **Started:** 2026-04-07T10:39:04Z
+- **Completed:** 2026-04-07T10:41:05Z
+- **Tasks:** 2
+- **Files modified:** 2
+
+## Accomplishments
+
+- UserAccessCsvExportService: BuildCsv (per-user with summary block), WriteAsync (one file per user), WriteSingleFileAsync (combined for SaveFileDialog) — RFC 4180 escaping, UTF-8+BOM
+- UserAccessHtmlExportService: self-contained HTML with stats cards, per-user summary cards, dual-view toggle (By User / By Site), collapsible group headers, sortable columns (per-group), text filter scoped to active view
+- Risk highlighting: high-privilege rows bold + warning icon, high-privilege user cards with red left border, external user guest badge (orange pill)
+
+## Task Commits
+
+1. **Task 1: Implement UserAccessCsvExportService** - `9f891aa` (feat)
+2. **Task 2: Implement UserAccessHtmlExportService** - `3146a04` (feat)
+
+**Plan metadata:** (docs commit pending)
+
+## Files Created/Modified
+
+- `SharepointToolbox/Services/Export/UserAccessCsvExportService.cs` — Per-user and combined CSV export with summary headers
+- `SharepointToolbox/Services/Export/UserAccessHtmlExportService.cs` — Interactive HTML report with dual-view toggle, collapsible groups, inline CSS/JS
+
+## Decisions Made
+
+1. **Two CSV write modes** — WriteAsync writes one file per user to a directory (batch export); WriteSingleFileAsync writes all users to one file (for ViewModel's SaveFileDialog flow, simpler UX).
+
+2. **Group-scoped sort** — sortTable() collects and re-inserts rows within each group individually, so sorting by "Permission Level" in the by-user view keeps each user's rows together.
+
+3. **Filter hides empty group headers** — filterTable() tracks which groups have at least one visible row, then hides group headers for empty groups to avoid orphaned section labels.
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Issues Encountered
+
+None.
+
+## User Setup Required
+
+None - no external service configuration required.
+
+## Next Phase Readiness
+
+- Both export services ready for wiring into the UserAccessAuditViewModel export commands (07-04)
+- CSV: ViewModel calls WriteSingleFileAsync(entries, filePath, ct) after SaveFileDialog
+- HTML: ViewModel calls WriteAsync(entries, filePath, ct) after SaveFileDialog
+- Both services are stateless and constructable without DI parameters
