decisions:
|

- "RiskLevel enum uses ordinal ordering (High=0) so Min() gives highest risk"
|
|
- "Unknown/custom roles default to Medium risk (conservative — forces admin review)"
|
|
- "SimplifiedPermissionEntry is a class (not record) to support passthrough properties for DataGrid binding"
|
|
- "PermissionSummaryBuilder always returns all 4 risk levels even with count 0 for consistent UI layout"

# 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)
|
