--- phase: 11-html-export-branding plan: 02 subsystem: export tags: [html-export, branding, csharp, tdd, dotnet] # Dependency graph requires: - phase: 11-01 provides: ReportBranding record and BrandingHtmlHelper.BuildBrandingHeader static method provides: - HtmlExportService with optional ReportBranding? branding parameter on BuildHtml and WriteAsync - SearchHtmlExportService with optional ReportBranding? branding parameter - StorageHtmlExportService with optional ReportBranding? branding parameter (both overloads) - DuplicatesHtmlExportService with optional ReportBranding? branding parameter - UserAccessHtmlExportService with optional ReportBranding? branding parameter - 7 new branding tests across all 5 export test files affects: - 11-03 (ViewModels assemble ReportBranding and pass to export services) # Tech tracking tech-stack: added: [] patterns: - "Optional nullable parameter after CancellationToken ct in WriteAsync for backward compat" - "Raw string literal split at body/h1 boundary to inject branding header between them" - "sb.Append (not AppendLine) for branding header — BrandingHtmlHelper already appends newlines" key-files: created: [] modified: - SharepointToolbox/Services/Export/HtmlExportService.cs - SharepointToolbox/Services/Export/SearchHtmlExportService.cs - SharepointToolbox/Services/Export/StorageHtmlExportService.cs - SharepointToolbox/Services/Export/DuplicatesHtmlExportService.cs - SharepointToolbox/Services/Export/UserAccessHtmlExportService.cs - SharepointToolbox.Tests/Services/Export/HtmlExportServiceTests.cs - SharepointToolbox.Tests/Services/Export/SearchExportServiceTests.cs - SharepointToolbox.Tests/Services/Export/StorageHtmlExportServiceTests.cs - SharepointToolbox.Tests/Services/Export/DuplicatesHtmlExportServiceTests.cs - SharepointToolbox.Tests/Services/Export/UserAccessHtmlExportServiceTests.cs key-decisions: - "branding parameter placed AFTER CancellationToken ct in WriteAsync signatures — existing positional callers unaffected" - "Raw string literals in SearchHtmlExportService, StorageHtmlExportService, DuplicatesHtmlExportService split at body/h1 boundary for injection" - "MakeBranding helper added locally to each test class rather than a shared base class — test files stay self-contained" # Metrics duration: 4min completed: 2026-04-08 --- # Phase 11 Plan 02: HTML Export Branding Injection Summary **Optional ReportBranding parameter wired into all 5 HTML export services; branding header injected between body and h1 via BrandingHtmlHelper; 7 new tests confirm injection and null-safety** ## Performance - **Duration:** ~4 min - **Started:** 2026-04-08T12:41:44Z - **Completed:** 2026-04-08T12:46:00Z - **Tasks:** 2 (Task 1: implementation, Task 2: TDD tests) - **Files modified:** 10 ## Accomplishments - Added `ReportBranding? branding = null` as last parameter to `BuildHtml` on all 5 export services - Added `ReportBranding? branding = null` after `CancellationToken ct` on all `WriteAsync` overloads (9 overloads total) - Inserted `sb.Append(BrandingHtmlHelper.BuildBrandingHeader(branding));` between `` and `

` in every exporter - Split raw string literals in 3 services (SearchHtml, StorageHtml, Duplicates) at the body/h1 boundary to enable injection - StorageHtmlExportService `_togIdx` reset logic left untouched (per plan pitfall guidance) - HtmlExportService both overloads updated (PermissionEntry and SimplifiedPermissionEntry) - StorageHtmlExportService both overloads updated (nodes-only and nodes+fileTypeMetrics) - Added `MakeBranding` helper to all 5 test classes; wrote 7 new tests (3 in HtmlExportServiceTests, 1 each in the other 4) - All 45 export tests pass; full suite: 247 passed / 0 failed / 26 skipped (skips are pre-existing integration tests) ## Task Commits Each task was committed atomically: 1. Task 1: Add branding parameter to all 5 HTML export services - `2233fb8` (feat) 2. Task 2: Extend export tests to verify branding injection - `d8b6616` (feat) ## Files Created/Modified - `SharepointToolbox/Services/Export/HtmlExportService.cs` - branding param + injection (2 BuildHtml, 2 WriteAsync) - `SharepointToolbox/Services/Export/SearchHtmlExportService.cs` - branding param + injection via raw string split - `SharepointToolbox/Services/Export/StorageHtmlExportService.cs` - branding param + injection (2 BuildHtml, 2 WriteAsync) - `SharepointToolbox/Services/Export/DuplicatesHtmlExportService.cs` - branding param + injection via raw string split - `SharepointToolbox/Services/Export/UserAccessHtmlExportService.cs` - branding param + injection - `SharepointToolbox.Tests/Services/Export/HtmlExportServiceTests.cs` - 3 new branding tests - `SharepointToolbox.Tests/Services/Export/SearchExportServiceTests.cs` - 1 new branding test - `SharepointToolbox.Tests/Services/Export/StorageHtmlExportServiceTests.cs` - 1 new branding test - `SharepointToolbox.Tests/Services/Export/DuplicatesHtmlExportServiceTests.cs` - 1 new branding test - `SharepointToolbox.Tests/Services/Export/UserAccessHtmlExportServiceTests.cs` - 1 new branding test ## Decisions Made - Placed `branding` AFTER `CancellationToken ct` in WriteAsync — avoids breaking any existing positional callers that pass ct by position - Used `sb.Append` (not `sb.AppendLine`) when inserting branding header — BrandingHtmlHelper already ends its output with a newline, so no double blank line - Raw string literals split at body/h1 boundary by closing the first literal after `` then re-opening for `

` — avoids string concatenation or interpolation awkwardness inside raw string blocks ## Deviations from Plan None - plan executed exactly as written. ## Issues Encountered None. ## User Setup Required None. ## Next Phase Readiness - All 5 HTML export services now accept `ReportBranding? branding = null` — Plan 11-03 ViewModels can assemble `ReportBranding` from `IBrandingService` and `TenantProfile` and pass it to any of these services - All existing callers compile unchanged (zero-regression confirmed by full test suite) - Build passes with 0 warnings --- Phase: 11-html-export-branding Completed: 2026-04-08
