requires:
  - phase: 10-branding-data-foundation
    provides: IBrandingService, BrandingService, ProfileService, LogoData, GraphClientFactory
provides:
  - UpdateProfileAsync on ProfileService for persisting profile changes
  - ImportLogoFromBytesAsync on IBrandingService for raw byte validation
  - BrowseMspLogoCommand and ClearMspLogoCommand on SettingsViewModel
  - BrowseClientLogoCommand, ClearClientLogoCommand, AutoPullClientLogoCommand on ProfileManagementViewModel

key-decisions:
  - "GraphClientFactory is not mockable (non-virtual) — tests use real instance without calling CreateClientAsync"
  - "ImportLogoAsync refactored to delegate to ImportLogoFromBytesAsync — eliminates code duplication"
  - "Type alias AppGraphClientFactory used to disambiguate from Microsoft.Graph.GraphClientFactory"

patterns-established:
  - "Logo command pattern: browse → ImportLogoAsync → persist; clear → null + persist"
  - "Auto-pull pattern: Graph API org branding → ImportLogoFromBytesAsync → persist to profile"

# Plan 11-04: Logo Management Commands + Service Extensions Summary

**MSP and client logo browse/clear/auto-pull commands on ViewModels, with ProfileService.UpdateProfileAsync and BrandingService.ImportLogoFromBytesAsync**

## Performance

- **Duration:** ~12 min
- **Tasks:** 2
- **Files modified:** 8

## Accomplishments
- ProfileService.UpdateProfileAsync persists profile changes (find-by-name, replace, save)
- BrandingService.ImportLogoFromBytesAsync validates raw bytes via magic byte detection, reuses compression logic
- ImportLogoAsync now delegates to ImportLogoFromBytesAsync (no duplication)
- SettingsViewModel exposes BrowseMspLogoCommand, ClearMspLogoCommand, MspLogoPreview property
- ProfileManagementViewModel exposes BrowseClientLogoCommand, ClearClientLogoCommand, AutoPullClientLogoCommand
- Auto-pull fetches squareLogo from Entra branding API, handles 404 gracefully
- All commands gated on SelectedProfile != null (CanExecute)

## Task Commits

1. **Task 1: UpdateProfileAsync + ImportLogoFromBytesAsync** - `9e850b0` (feat)
2. **Task 2: Logo management commands on ViewModels** - `b02b75e` (feat)

## Files Created/Modified
- `SharepointToolbox/Services/ProfileService.cs` - Added UpdateProfileAsync
- `SharepointToolbox/Services/IBrandingService.cs` - Added ImportLogoFromBytesAsync
- `SharepointToolbox/Services/BrandingService.cs` - Implemented ImportLogoFromBytesAsync, refactored ImportLogoAsync
- `SharepointToolbox/ViewModels/Tabs/SettingsViewModel.cs` - Added IBrandingService injection, MSP logo commands
- `SharepointToolbox/ViewModels/ProfileManagementViewModel.cs` - Added branding/graph injection, client logo commands
- `SharepointToolbox.Tests/ViewModels/SettingsViewModelLogoTests.cs` - 4 tests for MSP logo commands
- `SharepointToolbox.Tests/ViewModels/ProfileManagementViewModelLogoTests.cs` - 7 tests for client logo commands

## Decisions Made
- GraphClientFactory cannot be mocked with Moq (non-virtual methods) — used real instance in tests, auto-pull not tested E2E
- Used type alias `AppGraphClientFactory` to avoid conflict with Microsoft.Graph.GraphClientFactory

## Deviations from Plan
None - plan executed as specified.

## Issues Encountered
- Agent hit permission wall during test file creation; completed manually by orchestrator.

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- SettingsViewModel and ProfileManagementViewModel ready for Phase 12 UI integration
- All logo management commands exercisable without View
