+# 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.
