Phase 04 Plan 06: TemplateService + FolderStructureService Implementation Summary

CSOM site template capture/apply (libraries, folders, permission groups, logo) and CSV-driven folder hierarchy creation with parent-first BulkOperationRunner integration

Performance

• Duration: 10 min
• Started: 2026-04-03T09:57:13Z
• Completed: 2026-04-03T10:07:13Z
• Tasks: 2
• Files modified: 4

Accomplishments

• Implemented TemplateService with CaptureTemplateAsync (reads site structure via CSOM) and ApplyTemplateAsync (creates site via PnP Framework, recreates structure via CSOM)
• Implemented FolderStructureService with BuildUniquePaths (parent-first deduplication) and CreateFoldersAsync using BulkOperationRunner
• Created unit tests: 4 FolderStructureService tests (all pass) + 3 TemplateService tests (all pass), 3 live-SharePoint tests marked Skip

Task Commits

Each task was committed atomically:

1. Task 1: Implement TemplateService — already committed prior to this plan execution (verified via git log)
2. Task 2: FolderStructureService + tests - 84cd569 (feat)

Plan metadata: (added in final commit)

Files Created/Modified

• SharepointToolbox/Services/TemplateService.cs — Site template capture (reads Web, lists, folders, groups) and apply (PnP Framework site creation + CSOM structure recreation)
• SharepointToolbox/Services/FolderStructureService.cs — CSV row to folder hierarchy via BuildUniquePaths + BulkOperationRunner.RunAsync
• SharepointToolbox.Tests/Services/FolderStructureServiceTests.cs — 4 unit tests: interface impl, parent-first ordering, deduplication, empty levels
• SharepointToolbox.Tests/Services/TemplateServiceTests.cs — 3 unit tests: interface impl, SiteTemplate defaults, SiteTemplateOptions defaults

Decisions Made

• TemplateService uses using ModelSiteTemplate = SharepointToolbox.Core.Models.SiteTemplate alias — consistent with ITemplateService.cs established in Plan 04-01
• FolderStructureService.BuildUniquePaths sorts by slash depth (fewer slashes = shallower path = parent) — guarantees parent folders are created before children when SharePoint's Folders.Add does not create intermediates
• ApplyTemplateAsync creates a new ClientContext(siteUrl) for the newly created site — the adminCtx.Url is the admin site URL, not the new site

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Plan's BuildUniquePaths_DuplicateRows_Deduplicated expected count was incorrect

• Found during: Task 2 (writing unit tests)
• Issue: Plan specified Assert.Equal(4, paths.Count) for rows {A,B}, {A,B}, {A,C} which produces 3 unique paths: "A", "A/B", "A/C"
• Fix: Changed expected count from 4 to 3 to match correct deduplication behavior
• Files modified: SharepointToolbox.Tests/Services/FolderStructureServiceTests.cs
• Verification: Test passes with correct assertion
• Committed in: 84cd569 (Task 2 commit)

---

Total deviations: 1 auto-fixed (1 x Rule 1 - plan spec bug in test expectation) Impact on plan: Corrected incorrect test expectation; actual BuildUniquePaths behavior is correct. No scope creep.

Issues Encountered

• Transient WPF build file locking (.msCoverageSourceRootsMapping_*, CoverletSourceRootsMapping_*) required deleting locked coverage files and creating root obj/ directory before builds succeeded. This is an established environment issue unrelated to code changes.
• TemplateService.cs was already committed in a prior plan agent's docs commit — verified content matches plan spec exactly (372 lines, full implementation).

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• TemplateService and FolderStructureService are ready for Plan 04-07 (ViewModels for template and folder operations)
• Both services use BulkOperationRunner for per-item error handling, consistent with Plans 04-03 to 04-05
• All 122 tests pass (0 failures) across the full test suite

Self-Check: PASSED

All files found, all commits verified.
