Phase 11 Plan 01: ReportBranding Model and BrandingHtmlHelper Summary

ReportBranding DTO and BrandingHtmlHelper static class producing flex-layout data-URI branding header HTML for all 5 HTML export services

Performance

• Duration: ~15 min
• Started: 2026-04-08T12:31:52Z
• Completed: 2026-04-08T12:46:00Z
• Tasks: 1 (TDD: RED → GREEN)
• Files modified: 4

Accomplishments

• Created ReportBranding positional record bundling nullable MspLogo and ClientLogo LogoData properties
• Created BrandingHtmlHelper static class with BuildBrandingHeader covering all 4 logo states: null branding, both null, single logo, both logos
• Wrote 8 unit tests (TDD) asserting HTML structure: data-URI format, flex layout, max-height/max-width, spacer presence/absence
• Added InternalsVisibleTo to project file enabling tests to access internal BrandingHtmlHelper

Task Commits

Each task was committed atomically:

1. Task 1: Create ReportBranding record and BrandingHtmlHelper with tests - 212c439 (feat)

Plan metadata: (final metadata commit — see below)

Note: TDD task completed in single commit (RED confirmed via build error, GREEN verified with all 8 tests passing)

Files Created/Modified

• SharepointToolbox/Core/Models/ReportBranding.cs - Positional record with MspLogo and ClientLogo nullable LogoData properties
• SharepointToolbox/Services/Export/BrandingHtmlHelper.cs - Internal static class generating flex branding header HTML fragment
• SharepointToolbox.Tests/Services/Export/BrandingHtmlHelperTests.cs - 8 unit tests covering all logo combination states
• SharepointToolbox/SharepointToolbox.csproj - Added InternalsVisibleTo for SharepointToolbox.Tests

Decisions Made

• Used AssemblyAttribute ItemGroup in .csproj instead of AssemblyInfo.cs for InternalsVisibleTo — consistent with modern SDK-style project approach
• BrandingHtmlHelper stays internal — it is purely an implementation detail of the export services layer, not a public API

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• ReportBranding and BrandingHtmlHelper are ready for Plan 02 which adds optional branding parameters to all 5 HTML export services
• All 8 unit tests pass; build succeeds with 0 warnings
