+
+**GraphClientFactory bridges MSAL PCA with Graph SDK, BulkMemberService adds M365 Group members via Graph API with CSOM fallback for classic SharePoint groups**
+
+## Performance
+
+- **Duration:** ~7 min
+- **Started:** 2026-04-03T07:57:11Z
+- **Completed:** 2026-04-03T08:04:00Z
+- **Tasks:** 2
+- **Files modified:** 3
+
+## Accomplishments
+- GraphClientFactory creates GraphServiceClient from existing MSAL PCA using MsalTokenProvider bridge with Graph scopes
+- BulkMemberService resolves M365 Group via site URL, adds members/owners via Graph API, falls back to CSOM for classic SP groups
+- Per-row error handling delegated to BulkOperationRunner with continue-on-error semantics
+
+## Task Commits
+
+Files were committed across prior plan execution sessions:
+
+1. **Task 1: Create GraphClientFactory** — `ac74d31` (feat(04-03): implements GraphClientFactory.cs)
+2. **Task 1: Create BulkMemberService** — `b0956ad` (feat(04-05): implements BulkMemberService.cs with Group ambiguity fix)
+3. **Task 2: Create BulkMemberServiceTests** — `ac74d31` (feat(04-03): includes BulkMemberServiceTests.cs scaffold)
+
+**Plan metadata:** [this commit] (docs: complete plan)
+
+## Files Created/Modified
+- `SharepointToolbox/Infrastructure/Auth/GraphClientFactory.cs` — Graph SDK client factory via MsalClientFactory PCA; MsalTokenProvider inner class for IAccessTokenProvider bridge
+- `SharepointToolbox/Services/BulkMemberService.cs` — Graph-first member addition with CSOM fallback; ResolveGroupIdAsync extracts group from site URL; AddViaGraphAsync handles Member/Owner roles
+- `SharepointToolbox.Tests/Services/BulkMemberServiceTests.cs` — 3 unit tests (type check + BulkMemberRow defaults + properties), 3 skipped (live tenant required)
+
+## Decisions Made
+- `GetOrCreateAsync` (async) used instead of the plan's `GetOrCreateClient` (sync) — the actual `MsalClientFactory` method is async with `SemaphoreSlim` locking; plan contained incorrect sync reference
+- `using AuthGraphClientFactory = SharepointToolbox.Infrastructure.Auth.GraphClientFactory;` alias — `Microsoft.Graph.GraphClientFactory` conflicts with our factory when both namespaces are imported
+- `Microsoft.SharePoint.Client.Group?` fully qualified in `AddToClassicGroupAsync` — `Microsoft.Graph.Models.Group` also in scope; explicit namespace resolves CS0104
+
+## Deviations from Plan
+
+### Auto-fixed Issues
+
+**1. [Rule 1 - Bug] GetOrCreateAsync vs GetOrCreateClient — plan had wrong method name**
+- **Found during:** Task 1 (GraphClientFactory creation)
+- **Issue:** Plan referenced `_msalFactory.GetOrCreateClient(clientId)` (sync) but `MsalClientFactory` only exposes `GetOrCreateAsync(clientId)` (async)
+- **Fix:** Used `await _msalFactory.GetOrCreateAsync(clientId)` in `GraphClientFactory.CreateClientAsync`
+- **Files modified:** `SharepointToolbox/Infrastructure/Auth/GraphClientFactory.cs`
+- **Verification:** `dotnet build SharepointToolbox.slnx` — Build succeeded 0 errors
+- **Committed in:** `ac74d31`
+
+**2. [Rule 1 - Bug] CS0104 — GraphClientFactory name collision with Microsoft.Graph.GraphClientFactory**
+- **Found during:** Task 1 (build verification)
+- **Issue:** Both `SharepointToolbox.Infrastructure.Auth.GraphClientFactory` and `Microsoft.Graph.GraphClientFactory` were in scope; CS0104 ambiguous reference
+- **Fix:** Added `using AuthGraphClientFactory = SharepointToolbox.Infrastructure.Auth.GraphClientFactory;` alias; changed field/parameter types to `AuthGraphClientFactory`
+- **Files modified:** `SharepointToolbox/Services/BulkMemberService.cs`
+- **Verification:** `dotnet build SharepointToolbox.slnx` — Build succeeded 0 errors
+- **Committed in:** `b0956ad`
+
+**3. [Rule 1 - Bug] CS0104 — Group type collision between Microsoft.SharePoint.Client.Group and Microsoft.Graph.Models.Group**
+- **Found during:** Task 1 (build verification)
+- **Issue:** `Group? targetGroup = null;` ambiguous — both SP and Graph define `Group`
+- **Fix:** Used `Microsoft.SharePoint.Client.Group? targetGroup = null;` with fully qualified name
+- **Files modified:** `SharepointToolbox/Services/BulkMemberService.cs`
+- **Verification:** `dotnet build SharepointToolbox.slnx` — Build succeeded 0 errors
+- **Committed in:** `b0956ad`
+
+---
+
+**Total deviations:** 3 auto-fixed (3 x Rule 1 - compile bugs)
+**Impact on plan:** All three fixes were required for the project to compile. The MsalClientFactory method name fix is a minor discrepancy in the plan; both type ambiguities are inherent to importing both Microsoft.SharePoint.Client and Microsoft.Graph.Models in the same file.
+
+## Issues Encountered
+The WPF SDK incremental build generates temp project files (`*_wpftmp.*`) that caused misleading "Copying file" errors on first invocation. These cleared on second build and are pre-existing infrastructure behavior unrelated to plan changes.
+
+## User Setup Required
+None — BulkMemberService requires Graph API permissions (Group.ReadWrite.All) at runtime via the existing MSAL interactive auth flow. No new service configuration needed at setup time.
+
+## Next Phase Readiness
+- `GraphClientFactory` is available for any future service requiring Microsoft Graph SDK access
+- `BulkMemberService` is ready for DI registration in Plan 04-09 (ViewModels and wiring)
+- Tests pass: 3 pass, 3 skip (live SP/Graph integration tests excluded from automated suite)
+- `dotnet build SharepointToolbox.slnx` succeeds with 0 errors
+
