+# Phase 08 Plan 01: Permission Data Models and Mapping Layer Summary
+
+RiskLevel enum, PermissionLevelMapping static helper with 11 standard SharePoint role mappings, SimplifiedPermissionEntry wrapper preserving PermissionEntry immutability, and PermissionSummaryBuilder for grouped risk-level counts.
+
+## Tasks Completed
+
+### Task 1: Create RiskLevel enum and PermissionLevelMapping helper
+- **Commit:** f1390ea
+- **Files:** RiskLevel.cs, PermissionLevelMapping.cs
+- Created 4-value RiskLevel enum (High, Medium, Low, ReadOnly)
+- PermissionLevelMapping maps 11 standard SharePoint roles to plain-language labels
+- Case-insensitive dictionary lookup with Medium fallback for unknown roles
+- GetMapping, GetMappings, GetHighestRisk, GetSimplifiedLabels methods
+
+### Task 2: Create SimplifiedPermissionEntry wrapper and PermissionSummary model
+- **Commit:** 6609f2a
+- **Files:** SimplifiedPermissionEntry.cs, PermissionSummary.cs
+- SimplifiedPermissionEntry wraps PermissionEntry via Inner property
+- Computed SimplifiedLabels, RiskLevel, and Mappings at construction time
+- All 9 passthrough properties for DataGrid binding compatibility
+- Static WrapAll factory method for bulk conversion
+- PermissionSummary record with Label, RiskLevel, Count, DistinctUsers
+- PermissionSummaryBuilder.Build returns all 4 risk levels for consistent UI binding
+
+## Deviations from Plan
+
+None - plan executed exactly as written.
+
+## Verification Results
+
+- dotnet build succeeded with 0 errors, 0 warnings
+- RiskLevel.cs has High, Medium, Low, ReadOnly values
+- PermissionLevelMapping has 11 known role mappings
+- SimplifiedPermissionEntry wraps PermissionEntry without modifying it
+- PermissionSummaryBuilder.Build returns 4 summary entries
+- PermissionEntry.cs confirmed unmodified (git diff empty)
+
+## Self-Check: PASSED
+
+All 4 created files exist on disk. Both task commits (f1390ea, 6609f2a) verified in git log.
