## Goal Achievement

### Observable Truths

Combined must-haves from Plan 01 and Plan 02.

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | LocationInfo record holds five location fields from UserAccessEntry | VERIFIED | Record at `SharepointToolbox/Core/Models/LocationInfo.cs` declares exactly SiteUrl, SiteTitle, ObjectTitle, ObjectUrl, ObjectType |
| 2 | ConsolidatedPermissionEntry holds key fields plus IReadOnlyList<LocationInfo> with LocationCount | VERIFIED | Record at `SharepointToolbox/Core/Models/ConsolidatedPermissionEntry.cs` — all 8 positional params present, computed `LocationCount => Locations.Count` confirmed |
| 3 | PermissionConsolidator.Consolidate merges entries with identical key into single rows | VERIFIED | LINQ GroupBy+Select in `PermissionConsolidator.cs` lines 31-57; test `Consolidate_ThreeEntriesSameKey_ReturnsOneRowWithThreeLocations` passes |
| 4 | MakeKey uses pipe-delimited case-insensitive composite of UserLogin+PermissionLevel+AccessType+GrantedThrough | VERIFIED | `string.Join("\|", ...)` with `.ToLowerInvariant()` on string fields; `MakeKey_ProducesPipeDelimitedLowercaseFormat` passes |
| 5 | Empty input returns empty list | VERIFIED | `if (entries.Count == 0) return Array.Empty<>()` at line 33; `Consolidate_EmptyInput_ReturnsEmptyList` passes |
| 6 | Single entry produces 1 consolidated row with 1 location | VERIFIED | `Consolidate_SingleEntry_ReturnsOneRowWithOneLocation` passes |
| 7 | 3 entries with same key produce 1 row with 3 locations | VERIFIED | `Consolidate_ThreeEntriesSameKey_ReturnsOneRowWithThreeLocations` passes |
| 8 | Entries with different keys remain separate rows | VERIFIED | `Consolidate_DifferentKeys_RemainSeparateRows` passes |
| 9 | Key matching is case-insensitive | VERIFIED | `Consolidate_CaseInsensitiveKey_MergesCorrectly` passes — "ALICE@CONTOSO.COM" and "alice@contoso.com" merge to 1 row |
| 10 | MakeKey produces expected pipe-delimited format | VERIFIED | `MakeKey_ProducesPipeDelimitedLowercaseFormat` asserts exact string "alice@contoso.com\|full control\|Direct\|direct permissions" — passes |
| 11 | 11-row input with 3 duplicate pairs produces 7 rows | VERIFIED | `Consolidate_TenRowsWithThreeDuplicatePairs_ReturnsSevenRows` passes; plan adjusted to 11 inputs (noted deviation) |
| 12 | LocationCount matches Locations.Count | VERIFIED | `Consolidate_MergedEntry_LocationCountMatchesLocationsCount` passes |
| 13 | IsHighPrivilege and IsExternalUser preserved from first entry | VERIFIED | `Consolidate_PreservesIsHighPrivilegeAndIsExternalUser` passes |
| 14 | Existing solution builds with no compilation errors | VERIFIED | `dotnet build SharepointToolbox/SharepointToolbox.csproj --no-restore -v q` → 0 errors, 0 warnings |
| 15 | 9 [Fact] tests all pass | VERIFIED | `dotnet test --filter PermissionConsolidatorTests` → 9/9 passed |

**Score:** 15/15 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `SharepointToolbox/Core/Models/LocationInfo.cs` | Location data record with 5 fields | VERIFIED | 13 lines; `public record LocationInfo(string SiteUrl, string SiteTitle, string ObjectTitle, string ObjectUrl, string ObjectType)` — exact match to plan spec |
| `SharepointToolbox/Core/Models/ConsolidatedPermissionEntry.cs` | Consolidated permission model with Locations + LocationCount | VERIFIED | 21 lines; positional record with 8 params + computed `LocationCount` property |
| `SharepointToolbox/Core/Helpers/PermissionConsolidator.cs` | Static helper with Consolidate and MakeKey | VERIFIED | 59 lines; `public static class PermissionConsolidator` with `internal static string MakeKey` and `public static IReadOnlyList<ConsolidatedPermissionEntry> Consolidate` |
| `SharepointToolbox.Tests/Helpers/PermissionConsolidatorTests.cs` | Unit tests for PermissionConsolidator (min 120 lines) | VERIFIED | 256 lines; 9 [Fact] methods; private MakeEntry factory helper |

---

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| `PermissionConsolidator.cs` | `UserAccessEntry.cs` | `IReadOnlyList<UserAccessEntry>` parameter | VERIFIED | Line 31: `public static IReadOnlyList<ConsolidatedPermissionEntry> Consolidate(IReadOnlyList<UserAccessEntry> entries)` |
| `PermissionConsolidator.cs` | `ConsolidatedPermissionEntry.cs` | returns `IReadOnlyList<ConsolidatedPermissionEntry>` | VERIFIED | Return type on line 30-31; `new ConsolidatedPermissionEntry(...)` constructed at lines 45-53 |
| `PermissionConsolidator.cs` | `LocationInfo.cs` | `new LocationInfo(...)` in GroupBy Select | VERIFIED | Lines 41-43: `new LocationInfo(e.SiteUrl, e.SiteTitle, e.ObjectTitle, e.ObjectUrl, e.ObjectType)` |
| `PermissionConsolidatorTests.cs` | `PermissionConsolidator.cs` | calls Consolidate and MakeKey via InternalsVisibleTo | VERIFIED | Lines 46, 61, 81, 100, 118, 137, 207, 229, 247 call `PermissionConsolidator.Consolidate`; line 137 calls `PermissionConsolidator.MakeKey` |
| `PermissionConsolidatorTests.cs` | `UserAccessEntry.cs` | constructs test instances | VERIFIED | `MakeEntry` factory at line 32 calls `new UserAccessEntry(...)` |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| RPT-04 | 15-01, 15-02 | Consolidated reports merge rows for the same user with identical access levels across multiple locations into a single row | SATISFIED | `PermissionConsolidator.Consolidate` implements the merge; 9 unit tests validate all edge cases including the 7-row consolidation scenario; `dotnet test` passes 9/9 |

No orphaned requirements found: REQUIREMENTS.md maps RPT-04 to Phase 15 only, and both plans claim RPT-04. Coverage is complete.

---

### Anti-Patterns Found

None. Scan of all four phase files found no TODOs, FIXMEs, placeholders, empty returns, or stub implementations.

---

### Human Verification Required

None. All goal behaviors are fully verifiable programmatically: model structure, merge logic, and test coverage are code-level facts confirmed by compilation and test execution.

---

### Notes on Deviations (Informational)

The SUMMARY for Plan 02 documents one auto-corrected deviation from the plan: the RPT-04-g test uses 11 input rows (not 10) to correctly produce 7 output rows. The plan's arithmetic was wrong (10 inputs as described only yield 6 consolidated groups, not 7). The implementation used 11 inputs and 4 unique entries to achieve the specified 7-row output. The test passes and the behavior matches the requirement (7 consolidated rows). This is not a gap — the requirement and test are correct; only the plan's commentary was imprecise.

The `UserAccessAuditViewModelTests.CanExport_true_when_has_results` test failure in the full test suite (`1 Failed, 294 Passed, 26 Skipped`) is pre-existing and unrelated to Phase 15. That test file was last modified in commit `35b2c2a` (phase 07), which predates all phase 15 commits. No phase 15 commit touched the file.

---

## Summary

Phase 15 goal is fully achieved. The data shape and merge logic exist as three production files (LocationInfo, ConsolidatedPermissionEntry, PermissionConsolidator) and are proven testable in isolation by 9 passing unit tests that cover all specified edge cases. No UI code was touched. The solution builds cleanly. Phase 16 can wire `PermissionConsolidator.Consolidate` into the export pipeline with confidence.
