Phase 7 Plan 01: Data Models and Service Interfaces Summary

One-liner: Contract layer with UserAccessEntry record (12-field denormalized model), AccessType enum, IUserAccessAuditService, IGraphUserSearchService, and GraphUserResult — zero-error foundation for all downstream Phase 7 plans.

What Was Built

Three files establishing the Wave 1 contract layer for the User Access Audit feature:

1. UserAccessEntry.cs — C# record with 12 positional properties representing one row in the audit results grid. Includes AccessType enum (Direct/Group/Inherited), pre-computed IsHighPrivilege and IsExternalUser flags, and SiteUrl/SiteTitle for multi-site grouping.

2. IUserAccessAuditService.cs — Service interface with single method AuditUsersAsync that accepts a session manager, list of target user login names, list of sites, scan options, progress reporter, and cancellation token. Returns IReadOnlyList<UserAccessEntry>.

3. IGraphUserSearchService.cs — Service interface with SearchUsersAsync for Graph API people-picker autocomplete, plus the GraphUserResult record (DisplayName, UserPrincipalName, nullable Mail).

Tasks

#	Task	Status	Commit
1	Create UserAccessEntry model and AccessType enum	Done	e08df0f
2	Create IUserAccessAuditService and IGraphUserSearchService interfaces	Done	1a6989a

Decisions Made

1. Denormalized record design — Each UserAccessEntry row represents one user + one object + one permission level. This avoids nested object graphs and allows direct DataGrid binding and CSV export without flattening logic.

2. Pre-computed flags — IsHighPrivilege (Full Control, Site Collection Administrator) and IsExternalUser (#EXT# in login) are computed during the scan pass, not at display time. This keeps the ViewModel simple and the grid row data self-contained.

3. GraphUserResult co-located with interface — Defined in the same file as IGraphUserSearchService since it is exclusively used as the return type of that interface. No separate file needed.

Deviations from Plan

None — plan executed exactly as written.

Verification

• dotnet build SharepointToolbox/SharepointToolbox.csproj — 0 errors, 0 warnings
• UserAccessEntry.cs: record with 12 fields + AccessType enum confirmed
• IUserAccessAuditService.cs: AuditUsersAsync with correct 6-parameter signature confirmed
• IGraphUserSearchService.cs: SearchUsersAsync with 4 parameters + GraphUserResult record confirmed
