+
+# Phase 10 Context: Branding Data Foundation
+
+## Decided Areas (from prior research + STATE.md)
+
+These are locked — do not re-litigate during planning or execution.
+
+| Decision | Value |
+|---|---|
+| Logo storage format | Base64 strings in JSON (not file paths) |
+| MSP logo location | `BrandingSettings.cs` model → `branding.json` |
+| Client logo location | On `TenantProfile` model (per-tenant) |
+| File path after import | Discarded — only base64 persists |
+| SVG support | Rejected (XSS risk) — PNG/JPG only |
+| User directory service | New `GraphUserDirectoryService`, separate from `GraphUserSearchService` |
+| Directory auto-load | No — explicit "Load Directory" button required |
+| New NuGet packages | None — existing stack covers everything |
+| Export service signature | Optional `ReportBranding? branding = null` parameter on existing export methods |
+
+## Discussed Areas
+
+### 1. Logo Metadata Model
+
+**Decision:** Store base64 + MIME type as separate fields in a shared `LogoData` record.
+
+- Shared model: `LogoData { string Base64, string MimeType }` — used by both MSP logo (in `BrandingSettings`) and client logo (on `TenantProfile`)
+- `MimeType` is `"image/png"` or `"image/jpeg"`, determined at import time from magic bytes
+- No other metadata stored — no original filename, dimensions, or import date
+- Export services concatenate `data:{MimeType};base64,{Base64}` for HTML `<img>` tags
+- WPF preview converts `Base64` bytes to `BitmapImage` directly
+
+### 2. Logo Validation & Compression
+
+**Decision:** Validate format via magic bytes, auto-compress oversized files silently.
+
+- **Format detection:** Read file header magic bytes only — ignore file extension entirely
+  - PNG signature: `89 50 4E 47` (first 4 bytes)
+  - JPEG signature: `FF D8 FF` (first 3 bytes)
+  - Anything else → reject with specific error message (e.g., "File format is BMP, only PNG and JPG are accepted")
+- **Size handling:** If file exceeds 512 KB, auto-compress silently (no user notification)
+  - Strategy: resize dimensions (e.g., max 300px width/height) + reduce quality
+  - Keep original format — PNG stays PNG, JPEG stays JPEG (no format conversion)
+  - Compress until under 512 KB
+- **Dimension limits:** None — the 512 KB cap and compression handle naturally
+- **Validation errors:** Specific messages for format rejection (format-related only, since size is auto-handled)
+
+### 3. Profile Deletion & Duplication Behavior
+
+**Decision:** Warn about logo loss on deletion; do NOT copy logo on duplication.
+
+- **Deletion:** When deleting a tenant profile that has a client logo, the confirmation message explicitly mentions it: "This will also remove its client logo." The logo is embedded in the profile JSON, so deletion is automatic — no orphaned files.
+- **Duplication:** Duplicating a tenant profile copies connection fields (Name, TenantUrl, ClientId) but starts with a blank client logo. The user must re-import or auto-pull for the new profile. Rationale: duplicated profiles are typically for different tenants, so the logo shouldn't carry over.
+
+## Deferred Ideas (out of scope for Phase 10)
+
+- Logo preview in Settings UI (Phase 12)
+- Auto-pull client logo from Entra branding API (Phase 11/12)
+- Report header layout with logos side-by-side (Phase 11)
+- "Load Directory" button placement decision (Phase 14)
+- Session-scoped directory cache (UDIR-F01, deferred)
+
+## code_context
+
+| Asset | Path | Reuse |
+|---|---|---|
+| TenantProfile model | `SharepointToolbox/Core/Models/TenantProfile.cs` | Extend with `LogoData? ClientLogo` property |
+| AppSettings model | `SharepointToolbox/Core/Models/AppSettings.cs` | Reference for BrandingSettings pattern |
+| SettingsRepository | `SharepointToolbox/Infrastructure/Persistence/SettingsRepository.cs` | Clone pattern for BrandingRepository (write-then-replace + SemaphoreSlim) |
+| ProfileRepository | `SharepointToolbox/Infrastructure/Persistence/ProfileRepository.cs` | Already handles TenantProfile persistence — will serialize new logo field |
+| GraphUserSearchService | `SharepointToolbox/Services/GraphUserSearchService.cs` | Reference for Graph SDK usage, auth, and query patterns |
+| GraphClientFactory | `SharepointToolbox/Infrastructure/Auth/GraphClientFactory.cs` | Provides `GraphServiceClient` for new directory service |
+| DI registration | `SharepointToolbox/App.xaml.cs` (lines 73-163) | Register new BrandingRepository, BrandingService, GraphUserDirectoryService |
+| Profile deletion UI | `SharepointToolbox/ViewModels/ProfileManagementViewModel.cs` | Update deletion confirmation message to mention logo |

+# Milestone Audit: SharePoint Toolbox v2 — v1 Release
+
+**Audited:** 2026-04-07
+**Milestone:** v1 (5 phases, 42 requirements)
+**Verdict:** PASSED — all requirements satisfied, all phases integrated, build and tests green
+
+---
+
+## Phase Verification Summary
+
+| Phase | Status | Score | Verification |
+|-------|--------|-------|-------------|
+| 01 — Foundation | PASSED | 11/11 | 01-VERIFICATION.md |
+| 02 — Permissions | HUMAN_NEEDED | 7/7 automated | 02-VERIFICATION.md (2 human items pending) |
+| 03 — Storage & File Ops | **MISSING** | No VERIFICATION.md | Summaries exist for all 8 plans; integration checker confirmed all wiring |
+| 04 — Bulk Ops & Provisioning | HUMAN_NEEDED | 12/12 automated | 04-VERIFICATION.md (7 human items pending) |
+| 05 — Distribution & Hardening | HUMAN_NEEDED | 6/6 automated | 05-VERIFICATION.md (2 human items pending) |
+
+### Gap: Phase 03 Missing Verification
+
+Phase 03 has no `03-VERIFICATION.md` file. All 8 plan summaries exist and confirm code was delivered. The integration checker independently verified:
+- All 3 Phase 3 service interfaces (IStorageService, ISearchService, IDuplicatesService) registered in DI
+- All 5 export services registered and wired to ViewModels
+- All 4 Phase 3 tabs (Storage, Search, Duplicates + exports) wired in MainWindow
+- 13 Phase 3 requirements (STOR-01–05, SRCH-01–04, DUPL-01–03) covered
+
+**Recommendation:** Run a retroactive phase verification for Phase 03 or accept integration checker evidence as sufficient.
+
+---
+
+## Requirements Coverage
+
+All 42 v1 requirements are marked complete in REQUIREMENTS.md with phase traceability:
+
+| Category | IDs | Count | Status |
+|----------|-----|-------|--------|
+| Foundation | FOUND-01 to FOUND-12 | 12 | All SATISFIED |
+| Permissions | PERM-01 to PERM-07 | 7 | All SATISFIED |
+| Storage | STOR-01 to STOR-05 | 5 | All SATISFIED |
+| File Search | SRCH-01 to SRCH-04 | 4 | All SATISFIED |
+| Duplicates | DUPL-01 to DUPL-03 | 3 | All SATISFIED |
+| Templates | TMPL-01 to TMPL-04 | 4 | All SATISFIED |
+| Folder Structure | FOLD-01 to FOLD-02 | 2 | All SATISFIED |
+| Bulk Operations | BULK-01 to BULK-05 | 5 | All SATISFIED |
+| **Total** | | **42** | **42/42 mapped and complete** |
+
+**Orphaned requirements:** None
+**Unmapped requirements:** None
+
+---
+
+## Cross-Phase Integration
+
+Integration checker ran full verification. Results:
+
+| Check | Status |
+|-------|--------|
+| DI wiring (all 5 phases) | PASS — all services registered in App.xaml.cs |
+| MainWindow tabs (10 tabs) | PASS — all declared and wired from DI |
+| FeatureViewModelBase inheritance (10 VMs) | PASS |
+| SessionManager usage (9 ViewModels + SiteListService) | PASS |
+| ExecuteQueryRetryHelper (9 CSOM services, 40+ call sites) | PASS |
+| SharePointPaginationHelper (2 services using list enumeration) | PASS |
+| TranslationSource localization (15 XAML files, 170 bindings) | PASS |
+| TenantSwitchedMessage propagation | PASS |
+| Export chain completeness (all features) | PASS |
+| Build | PASS — 0 warnings, 0 errors |
+| Tests | PASS — 134 passed, 22 skipped (live CSOM), 0 failed |
+| EN/FR key parity | PASS — 199/199 keys |
+
+**Orphaned code:** `FeatureTabBase.xaml` — Phase 1 placeholder, now superseded by full tab views. Harmless dead code.
+
+---
+
+## Tech Debt & Deferred Items
+
+### From Phase Verifications
+
+| Item | Source | Severity | Description |
+|------|--------|----------|-------------|
+| Hardcoded export button text | Phase 2 | Info | `PermissionsView.xaml` uses `Content="Export CSV"` / `"Export HTML"` instead of `rad.csv.perms` / `rad.html.perms` localization keys. French users see English button labels. |
+| Missing Designer.cs property | Phase 2 | Info | `Strings.Designer.cs` lacks `tab_permissions` typed accessor. Runtime binding via `TranslationSource` works fine. |
+| No invalid-row highlighting | Phase 4 | Warning | `BulkMembersView.xaml`, `BulkSitesView.xaml`, `FolderStructureView.xaml` show IsValid as text column but lack `RowStyle` + `DataTrigger` for visual red highlighting on invalid rows. |
+| FeatureTabBase dead code | Phase 1→all | Info | `Views/Controls/FeatureTabBase.xaml` is no longer imported by any tab view after all phases replaced stubs. |
+| Cancel test locale mismatch | Phase 3 (03-08) | Info | `FeatureViewModelBaseTests.CancelCommand_DuringOperation_SetsStatusMessageToCancelled` asserts `.Contains("cancel")` but app returns French string "Opération annulée". Pre-existing; deferred. |
+
+### Deferred v2 Requirements
+
+These are explicitly out of scope for v1 and tracked in REQUIREMENTS.md:
+- UACC-01/02: User access audit across sites
+- SIMP-01/02/03: Simplified plain-language permission reports
+- VIZZ-01/02/03: Storage metrics graphs (pie/bar chart)
+
+---
+
+## Human Verification Backlog
+
+11 items across 3 phases require human confirmation (runtime UI/locale checks that cannot be automated):
+
+### Phase 2 (2 items)
+1. Full Permissions tab UI visual checkpoint (layout, disabled states, French locale)
+2. Export button localization decision (accept hardcoded English or bind to resx keys)
+
+### Phase 4 (7 items)
+1. Application launches with all 10 tabs visible
+2. Bulk Members — Load Example populates DataGrid with 7 rows
+3. Bulk Sites — semicolon CSV auto-detection works
+4. Invalid row display in DataGrid (IsValid=False, Errors column)
+5. Confirmation dialog appears before bulk operations
+6. Transfer tab — two-step browse flow (SitePickerDialog → FolderBrowserDialog)
+7. Templates tab — 5 capture checkboxes visible and checked by default
+
+### Phase 5 (2 items)
+1. Clean-machine EXE launch (no .NET runtime installed)
+2. French locale runtime rendering (diacritics display correctly in all tabs)
+
+---
+
+## Build & Test Summary
+
+| Metric | Value |
+|--------|-------|
+| Build | 0 errors, 0 warnings |
+| Tests passed | 134 |
+| Tests skipped | 22 (live CSOM — expected) |
+| Tests failed | 0 |
+| EN locale keys | 199 |
+| FR locale keys | 199 |
+| Published EXE | 200.9 MB self-contained |
+| Phases complete | 5/5 |
+| Requirements satisfied | 42/42 |
+
+---
+
+## Verdict
+
+**PASSED** — The milestone has achieved its definition of done:
+
+1. All 42 v1 requirements are implemented with real code and verified by phase-level checks
+2. All cross-phase integration points are wired (DI, messaging, shared infrastructure)
+3. Build compiles cleanly with zero warnings
+4. 134 automated tests pass with zero failures
+5. Self-contained 200.9 MB EXE produced successfully
+6. Full EN/FR locale parity (199 keys each)
+
+**Remaining actions before shipping:**
+- [ ] Complete 11 human verification items (UI visual checks, clean-machine launch)
+- [ ] Decide on Phase 03 retroactive verification (or accept integration check as sufficient)
+- [ ] Address 3 Warning-level tech debt items (invalid-row highlighting in bulk DataGrids)
+- [ ] Optionally clean up FeatureTabBase dead code and fix cancel test locale mismatch

 ## What This Is
 
-A full C#/WPF rewrite of an existing PowerShell-based SharePoint Online administration and auditing tool. The app lets IT administrators manage permissions, analyze storage, search files, detect duplicates, manage site templates, and perform bulk operations across SharePoint Online and Teams sites. It's a local desktop tool used by MSPs and IT teams managing multiple client tenants.
+A C#/WPF desktop application for IT administrators and MSPs to audit and manage SharePoint Online permissions, storage, files, and sites across multiple client tenants. Replaces a 6,400-line monolithic PowerShell script with a structured 10,071-line MVVM application shipping as a single self-contained EXE.
 
 ## Core Value
 
 Administrators can audit and manage SharePoint/Teams permissions and storage across multiple client tenants from a single, reliable desktop application.
 
+## Current State
+
+**Shipped:** v2.2 Report Branding & User Directory (2026-04-09)
+**Status:** Active — v2.3 Tenant Management & Report Enhancements
+
+## Current Milestone: v2.3 Tenant Management & Report Enhancements
+
+**Goal:** Streamline tenant onboarding with automated app registration, add self-healing ownership for access-denied sites, and enhance report output with group expansion and entry consolidation.

+- [ ] Automated app registration on target tenant with guided fallback
+- [ ] App removal from target tenant
+- [ ] Auto-take ownership of sites on access denied (global toggle)
+- [ ] Expand groups in HTML reports
+- [ ] Report consolidation toggle (merge duplicate entries)
 
 ### Out of Scope
 
-- Cross-platform support (Mac/Linux) — Windows-only desktop tool, MAUI/Avalonia not justified
+- Cross-platform support (Mac/Linux) — WPF is Windows-only; not justified for current user base
 - SQLite or database storage — JSON sufficient for config, profiles, and templates
 - Web-based UI — must remain a local desktop application
 - Cloud/SaaS deployment — local tool by design
 - Mobile support — desktop admin tool
+- Real-time monitoring / alerts — requires background service, beyond scope
+- Automated remediation (auto-revoke) — liability risk
+- Content migration between tenants — separate product category
 
 ## Context
 
-- **Existing codebase:** 6,400-line monolithic PowerShell script (`Sharepoint_ToolBox.ps1`) with WinForms UI
+- **v1.0 shipped** with full feature parity: permissions, storage, search, duplicates, bulk operations, templates, folder provisioning
-- **Current features to port:** Permissions reports, storage metrics, site templates, file search, duplicate detection, bulk operations (transfer, site creation, member addition), folder structure creation, localization (EN/FR)
+- **v1.1 shipped** with enhanced reports: user access audit, simplified permissions, storage charts, global site selection
-- **SharePoint integration:** Currently uses PnP.PowerShell module; C# rewrite will use PnP Framework / Microsoft Graph SDK
+- **v2.2 shipped** with report branding (logos in HTML exports) and user directory browse mode
-- **Authentication:** Currently interactive Azure AD OAuth via PnP; new version needs multi-tenant session caching
+- **Localization:** 230+ EN/FR keys, full parity verified
-- **Known issues in current app:** 38 silent catch blocks, 27 error suppressions, resource cleanup issues, UI freezes on large datasets, no operation cancellation
+- **Architecture:** 140+ C# files + 17 XAML files across Core/Infrastructure/Services/ViewModels/Views layers
-- **Localization:** English and French supported, key-based translation system
-- **Report exports:** CSV and interactive HTML reports with embedded JS for sorting/filtering
 
 ## Constraints
 
 - **Platform:** Windows desktop only — WPF requires Windows
-- **Distribution:** Self-contained EXE (~150MB) — no .NET runtime dependency for end users
+- **Distribution:** Self-contained EXE (~200 MB) — no .NET runtime dependency
-- **Auth method:** Interactive browser-based Azure AD login (no client secrets or certificates stored)
+- **Auth method:** Interactive browser-based Azure AD login (no client secrets stored)
-- **Data storage:** JSON files for profiles, settings, templates — same format as current app for migration
+- **Data storage:** JSON files for profiles, settings, templates
-- **SharePoint API:** PnP Framework / Microsoft Graph SDK for C# (replaces PnP.PowerShell)
+- **SharePoint API:** PnP Framework / Microsoft Graph SDK
 - **Local only:** No telemetry, no cloud services, no external dependencies at runtime

 ## Out of Scope
 
 | Feature | Reason |
 |---------|--------|
-| Cross-platform (Mac/Linux) | WPF is Windows-only; not justified for current user base |
+| Auto-revoke permissions | Liability risk — read-only auditing tool, not remediation |
-| Real-time monitoring / alerts | Requires background service, webhooks — turns desktop tool into a service |
+| Real-time ownership monitoring | Requires background service, beyond scope of desktop tool |
-| Automated remediation (auto-revoke) | Liability risk; one wrong rule destroys client access |
+| Group expansion in CSV reports | CSV format doesn't support expandable sections; consolidation covers the dedup need |
-| SQLite / database storage | Breaks single-EXE distribution; JSON sufficient |
+| Custom permission scope selection for app registration | Fixed scope set covers all Toolbox features; custom scopes add complexity without value |
-| Cloud sync / shared profiles | Requires server infrastructure — out of scope for local tool |
-| AI-powered recommendations | Competes with Microsoft's own Copilot roadmap |
-| Content migration between tenants | Separate product category (ShareGate territory) |
-| Mobile app | Desktop admin tool |
-| OAuth with client secrets/certificates | Interactive login only — no stored credentials |
-| Version history management | Deep separate problem; surface totals in storage metrics only |

+# Retrospective
+
+## Milestone: v1.0 — MVP
+
+**Shipped:** 2026-04-07
+**Phases:** 5 | **Plans:** 36 | **Commits:** 164 | **LOC:** 10,071
+
+### What Was Built
+- Complete C#/WPF rewrite replacing 6,400-line PowerShell monolith
+- 10 feature tabs: Permissions, Storage, Search, Duplicates, Transfer, Bulk Members, Bulk Sites, Folder Structure, Templates, Settings
+- Multi-tenant MSAL authentication with per-tenant token caching
+- CSV and interactive HTML export across all scan features
+- Bulk operations with continue-on-error, per-item reporting, retry, and cancellation
+- Self-contained 200 MB EXE with full EN/FR localization (199 keys)
+
+### What Worked
+- **Wave 0 scaffold pattern**: Creating models, interfaces, and test stubs before implementation gave every phase testable targets from day 1
+- **FeatureViewModelBase contract**: Establishing the async/cancel/progress pattern in Phase 1 meant Phases 2-4 had zero friction adding new features
+- **BulkOperationRunner abstraction**: One shared helper gave consistent error semantics across 4 different bulk operations
+- **Phase dependency ordering**: Foundation → Permissions → Storage → Bulk → Hardening prevented rework
+- **Atomic commits per task**: Each plan produced clear, reviewable commit history
+
+### What Was Inefficient
+- **Phase 03 missing verification**: The only phase without a VERIFICATION.md — caught during milestone audit, but should have been produced during execution
+- **Stale audit notes**: Phase 2 verification reported export buttons as hardcoded English, but they were actually already localized by the time of the audit — suggests verification reads code at a point-in-time snapshot that may not reflect later fixes
+- **Cancel test locale mismatch**: The French locale test failure was flagged in Phase 3 plan 08 summary but deferred until post-milestone cleanup — should have been fixed inline
+
+### Patterns Established
+- Write-then-replace JSON persistence with SemaphoreSlim for thread safety
+- TranslationSource singleton with PropertyChanged(string.Empty) for runtime culture switching
+- ExecuteQueryRetryHelper for throttle-aware CSOM calls (429/503 detection)
+- SharePointPaginationHelper with ListItemCollectionPosition for 5,000+ item lists
+- CsvValidationService with auto-delimiter detection (comma/semicolon) and BOM handling
+- DataGrid RowStyle DataTrigger for invalid-row visual highlighting
+
+### Key Lessons
+- Establish shared infrastructure patterns (auth, retry, pagination, progress) in Phase 1 — every subsequent phase benefits
+- Test scaffolds (Wave 0) eliminate the "no tests until the end" anti-pattern
+- Phase verifications should be mandatory during execution, not optional — catching Phase 03's gap at audit time is late
+- Localization tests (key parity + diacritic spot-checks) are cheap and catch real bugs

 ## Phase Details
 
-### Phase 1: Foundation
+### Phase 15: Consolidation Data Model
-**Goal**: The application shell runs, users can authenticate to multiple tenants and switch between them without re-logging in, all long-running operations are cancellable and report progress, all errors surface visibly, and the infrastructure patterns that prevent the existing app's 10 known pitfalls are in place before any feature work begins.
+**Goal**: The data shape and merge logic for report consolidation exist and are fully testable in isolation before any UI touches them
-**Depends on**: Nothing (first phase)
+**Depends on**: Nothing (no API calls, no UI dependencies)
-**Requirements**: FOUND-01, FOUND-02, FOUND-03, FOUND-04, FOUND-05, FOUND-06, FOUND-07, FOUND-08, FOUND-09, FOUND-10, FOUND-12
+**Requirements**: RPT-04
 **Success Criteria** (what must be TRUE):
-  1. User can create, rename, delete, and switch between tenant profiles via the UI — each profile stores tenant URL, client ID, and display name in a JSON file
+  1. A `ConsolidatedPermissionEntry` model exists that represents a single user's merged access across multiple locations with identical access levels
-  2. User can authenticate to a tenant via interactive browser login and the session persists across tenant switches without re-entering credentials (MSAL token cache per tenant)
+  2. A `PermissionConsolidator` service accepts a flat list of permission rows and returns a consolidated list where duplicate user+level rows are merged
-  3. User can see real-time progress on any long-running operation and cancel it mid-execution with a button — the operation stops cleanly with no silent continuation
+  3. Consolidation logic has unit test coverage — a known 10-row input with 3 duplicate pairs produces the expected 7-row output
-  4. When any operation fails, the user sees an actionable error message in the UI — no operation fails silently or swallows an exception
+  4. Existing HTML export services compile and produce identical output when consolidation is not applied (opt-in, defaults off)
-  5. UI language switches between English and French dynamically without restarting the application
+**Plans:** 2/2 plans complete
-**Plans**: 8 plans
-
 Plans:
-- [ ] 01-01-PLAN.md — Solution scaffold: WPF project + xUnit test project with Generic Host entry point
+- [x] 15-01-PLAN.md — Models (LocationInfo, ConsolidatedPermissionEntry) + PermissionConsolidator service
-- [ ] 01-02-PLAN.md — Core layer: models, messages, pagination helper, retry helper, LogPanelSink
+- [x] 15-02-PLAN.md — Unit tests (10 test cases) + full solution build verification
-- [ ] 01-03-PLAN.md — Persistence layer: ProfileRepository + SettingsRepository + services + unit tests
-- [ ] 01-04-PLAN.md — Auth layer: MsalClientFactory + SessionManager + unit tests
-- [ ] 01-05-PLAN.md — Localization + Serilog: TranslationSource, EN/FR resx, integration tests
-- [ ] 01-06-PLAN.md — ViewModels + WPF shell: FeatureViewModelBase, MainWindow XAML, global exception handlers
-- [ ] 01-07-PLAN.md — UI dialogs: ProfileManagementDialog + SettingsView wired into shell
-- [ ] 01-08-PLAN.md — Checkpoint: full test suite + visual verification of running application
 
-### Phase 2: Permissions
+### Phase 16: Report Consolidation Toggle
-**Goal**: Users can scan SharePoint permissions on one or many sites and export the results as both a raw CSV and a sortable, filterable HTML report — with no silent failures on large libraries and full control over scan scope.
+**Goal**: Users can choose to merge duplicate permission entries per export through a toggle in the export settings dialog
-**Depends on**: Phase 1
+**Depends on**: Phase 15
-**Requirements**: PERM-01, PERM-02, PERM-03, PERM-04, PERM-05, PERM-06, PERM-07
+**Requirements**: RPT-03
 **Success Criteria** (what must be TRUE):
-  1. User can select one site or multiple sites and run a permissions scan that returns owners, members, guests, external users, and broken inheritance items
+  1. A consolidation toggle is visible in the export settings dialog (or export options panel) and defaults to OFF
-  2. User can choose configurable scan depth and whether to include or exclude inherited permissions before running
+  2. When the toggle is OFF, the exported HTML report is byte-for-byte identical to the pre-v2.3 output
-  3. User can export the permissions results to a CSV file with all raw permission data
+  3. When the toggle is ON, the exported HTML report merges rows for the same user with identical access levels into a single row showing all affected locations
-  4. User can export the permissions results to an interactive HTML report where rows are sortable, filterable, and groupable by user
+  4. The toggle state is remembered for the session (does not reset between exports within the same session)
-  5. Scanning a library with more than 5,000 items completes successfully — the tool paginates automatically and does not silently truncate or fail
+**Plans:** 2/2 plans complete
-**Plans**: 7 plans
-
 Plans:
-- [x] 02-01-PLAN.md — Wave 0: test scaffolds (PermissionsService, ViewModel, classification, CSV, HTML export tests) + PermissionEntryHelper
+- [ ] 16-01-PLAN.md — ViewModel properties + XAML Export Options GroupBox + localization + CSV consolidation
-- [x] 02-02-PLAN.md — Core models + PermissionsService scan engine (PermissionEntry, ScanOptions, IPermissionsService, PermissionsService)
+- [ ] 16-02-PLAN.md — HTML consolidated rendering with expandable location sub-lists + full test verification
-- [x] 02-03-PLAN.md — SiteListService: tenant admin site listing for multi-site picker (ISiteListService, SiteListService, SiteInfo)
-- [x] 02-04-PLAN.md — Export services: CsvExportService (with row merging) + HtmlExportService (self-contained HTML)
-- [x] 02-05-PLAN.md — Localization: 15 Phase 2 EN/FR keys in Strings.resx, Strings.fr.resx, Strings.Designer.cs
-- [x] 02-06-PLAN.md — PermissionsViewModel + SitePickerDialog (XAML + code-behind)
-- [x] 02-07-PLAN.md — DI wiring + PermissionsView XAML + MainWindow tab replacement + visual checkpoint
 
-### Phase 3: Storage and File Operations
+### Phase 17: Group Expansion in HTML Reports
-**Goal**: Users can view and export storage metrics per site and library, search for files across sites using multiple criteria, and detect duplicate files and folders — all with consistent export options and no silent failures on large datasets.
+**Goal**: Users can expand SharePoint group entries in HTML reports to see the group's members, including members of nested groups
-**Depends on**: Phase 2
+**Depends on**: Phase 16
-**Requirements**: STOR-01, STOR-02, STOR-03, STOR-04, STOR-05, SRCH-01, SRCH-02, SRCH-03, SRCH-04, DUPL-01, DUPL-02, DUPL-03
+**Requirements**: RPT-01, RPT-02
 **Success Criteria** (what must be TRUE):
-  1. User can view storage consumption per library and per site (with configurable folder depth), including total size, version size, item count, and last modified date
+  1. SharePoint group rows in the HTML report render as expandable — clicking a group name reveals its member list inline
-  2. User can export storage metrics to CSV and to an interactive HTML with a collapsible tree view
+  2. Member resolution includes transitive membership: nested groups are recursively resolved so every leaf user is shown
-  3. User can search for files across sites using at least extension, name/regex, date range, creator, and editor as criteria — with a configurable result cap up to 50,000 items
+  3. Group expansion is triggered at export time via Graph API — the permission scan itself is unchanged
-  4. User can export file search results to CSV and to an interactive sortable/filterable HTML
+  4. When Graph cannot resolve a group's members (throttled or insufficient scope), the report shows the group row with a "members unavailable" label rather than failing the export
-  5. User can scan for duplicate files (by name, size, creation date, modification date) and duplicate folders (by name, subfolder count, file count) and export the results to an HTML with grouped display
+**Plans:** 2/2 plans complete
-**Plans**: 8 plans
-
 Plans:
-- [ ] 03-01-PLAN.md — Wave 0: test scaffolds + models (StorageNode, SearchResult, DuplicateGroup/Item, options) + interfaces (IStorageService, ISearchService, IDuplicatesService) + export stubs
+- [ ] 17-01-PLAN.md — ResolvedMember model + ISharePointGroupResolver service (CSOM + Graph transitive resolution) + DI registration

-### Phase 4: Bulk Operations and Provisioning
+### Phase 18: Auto-Take Ownership
-**Goal**: Users can execute bulk write operations (member additions, site creation, file transfer) with per-item error reporting and cancellation, capture site structures as reusable templates, apply templates to create new sites, and provision folder structures from CSV — all without silent partial failures.
+**Goal**: Users can enable automatic site collection admin elevation so that access-denied sites during scans no longer block audit progress
-**Depends on**: Phase 3
+**Depends on**: Phase 15
-**Requirements**: BULK-01, BULK-02, BULK-03, BULK-04, BULK-05, TMPL-01, TMPL-02, TMPL-03, TMPL-04, FOLD-01, FOLD-02
+**Requirements**: OWN-01, OWN-02
 **Success Criteria** (what must be TRUE):
-  1. User can transfer files and folders between sites with real-time progress tracking and can cancel mid-operation — transferred items are confirmed and failures are reported per-item
+  1. A global "Auto-take ownership on access denied" toggle exists in application settings and defaults to OFF
-  2. User can add members to groups in bulk from a CSV file — each row that fails is reported individually, not silently skipped
+  2. When the toggle is OFF, access-denied sites produce the same error behavior as before v2.3 (no regression)
-  3. User can create multiple sites in bulk from a CSV file with per-site error reporting and mid-operation cancellation
+  3. When the toggle is ON and a scan hits access denied on a site, the app automatically calls `Tenant.SetSiteAdmin` to elevate ownership and retries the site without interrupting the scan
-  4. User can capture an existing site's structure (libraries, folders, permission groups, logo, settings) as a named template stored in JSON, then apply that template to create a new Communication or Teams site
+  4. The scan result for an auto-elevated site is visually distinguishable from a normally-scanned site (e.g., a flag or icon in the results)
-  5. User can manage saved templates (create, rename, delete) and create folder structures on a target site from a CSV template
+**Plans:** 2/2 plans complete
-**Plans**: 10 plans

-### Phase 5: Distribution and Hardening
+### Phase 19: App Registration & Removal
-**Goal**: The application ships as a single self-contained EXE that runs on a machine with no .NET runtime installed, all previously identified reliability constraints are verified end-to-end (5,000-item pagination, JSON corruption recovery, throttling retry, cancellation), and the French locale is complete and tested.
+**Goal**: Users can register and remove the Toolbox's Azure AD application on a target tenant directly from the profile dialog, with a guided fallback when permissions are insufficient
-**Depends on**: Phase 4
+**Depends on**: Phase 18
-**Requirements**: FOUND-11
+**Requirements**: APPREG-01, APPREG-02, APPREG-03, APPREG-04, APPREG-05, APPREG-06
 **Success Criteria** (what must be TRUE):
-  1. Running the published EXE on a clean machine with no .NET runtime installed launches the application and all features function correctly
+  1. A "Register App" action is available in the profile create/edit dialog and is the recommended path for new tenant onboarding
-  2. The application recovers gracefully when a SharePoint API call is throttled (429/503) — the user sees a retry progress message and the operation eventually completes or surfaces a clear failure
+  2. Before attempting registration, the app checks for Global Admin role and surfaces a clear message if the signed-in user lacks the required permissions, then presents step-by-step manual registration instructions as a fallback
-  3. The French locale is complete for all UI strings — no English fallback text appears when the language is set to French
+  3. Registration creates the Azure AD application, service principal, and grants all required API permissions in a single atomic operation — if any step fails, all partial changes are rolled back and the user sees a specific error explaining what failed and why
-  4. A scan against a library with more than 5,000 items returns complete, correct results with no silent truncation verified against a known dataset
+  4. A "Remove App" action in the profile dialog removes the Azure AD application registration from the target tenant
-**Plans**: 3 plans
+  5. After removal, all cached MSAL tokens and session state for that tenant are cleared, and subsequent operations require re-authentication
-
+**Plans:** 2/2 plans complete

 ## Accumulated Context
 
 ### Decisions
 
 Decisions are logged in PROJECT.md Key Decisions table.
-Recent decisions affecting current work:
 
-- Foundation: Use PnP.Framework 1.18.0 (not PnP.Core SDK) — PnP Provisioning Engine lives only in PnP.Framework
+**v2.3 notable constraints:**
-- Foundation: Use MsalCacheHelper for per-tenant token cache serialization — scope IPublicClientApplication per ClientId
+- Phase 19 has the highest blast radius (Entra changes) — must be last
-- Foundation: Never set PublishTrimmed=true — PnP.Framework and MSAL use reflection; accept ~150-200 MB EXE
+- Phase 15 is zero-API-call foundation; unblocks Phase 16 (consolidation) and Phase 18 (ownership) independently
-- Foundation: Establish AsyncRelayCommand + IProgress<T> + CancellationToken patterns before any feature work — retrofitting is the most expensive WPF refactor
+- Group expansion (Phase 17) calls Graph at export time, not at scan time — scan pipeline unchanged
-- [Phase 01-foundation]: Upgraded MSAL from 4.83.1 to 4.83.3 — Extensions.Msal 4.83.3 requires MSAL >= 4.83.3; minor patch with no behavioral difference
+- Auto-take ownership uses PnP `Tenant.SetSiteAdmin` — requires Tenant Admin scope
-- [Phase 01-foundation]: Test project targets net10.0-windows with UseWPF=true — required to reference WPF main project; net10.0 is framework-incompatible
+- App registration must be atomic with rollback; partial Entra state is worse than no state
-- [Phase 01-foundation]: Solution uses .slnx format (new .NET 10 XML solution) — dotnet new sln creates .slnx by default in .NET 10 SDK
+- [Phase 15]: MakeKey declared internal for test access via InternalsVisibleTo without exposing as public API
-- [Phase 01-foundation]: TenantProfile is a plain mutable class (not record) — System.Text.Json requires settable properties; field names Name/TenantUrl/ClientId match JSON schema exactly
+- [Phase 15]: LINQ GroupBy+Select for consolidation merge instead of mutable dictionary — consistent with functional codebase style
-- [Phase 01-foundation]: SharePointPaginationHelper uses [EnumeratorCancellation] on ct — required for correct WithCancellation() forwarding in async iterators
+- [Phase 15-consolidation-data-model]: RPT-04-g test data uses 11 rows (not 10) to produce 7 consolidated rows — plan description had a counting error; 4 unique rows + 3 merged groups = 7
-- [Phase 01-foundation]: Explicit System.IO using required in WPF project — WPF temp build project does not include System.IO in implicit usings; all persistence classes need explicit import
+- [Phase 16-01]: Consolidated branch uses early-return pattern inside WriteSingleFileAsync to leave existing code path untouched
-- [Phase 01-foundation]: SettingsService validates only 'en' and 'fr' language codes — throws ArgumentException for unsupported codes
+- [Phase 16-01]: PermissionsViewModel gets MergePermissions as no-op placeholder reserved for future use
-- [Phase 01-foundation]: LoadAsync on corrupt JSON throws InvalidDataException (not silent empty) — explicit failure protects against silent data loss
+- [Phase 16-report-consolidation-toggle]: BuildConsolidatedHtml is a private method via early-return in BuildHtml — existing code path completely untouched
-- [Phase 01-foundation]: Strings.Designer.cs maintained manually — ResXFileCodeGenerator is VS-only, not run by dotnet build; only ResourceManager accessor needed
+- [Phase 16-report-consolidation-toggle]: Separate locIdx counter for location groups (loc0, loc1...) distinct from grpIdx for user groups (ugrp0...) prevents ID collision
-- [Phase 01-foundation]: EmbeddedResource uses Update not Include in SDK-style project — SDK auto-includes all .resx; Include causes NETSDK1022 duplicate error
+- [Phase 17]: Static helpers IsAadGroup/ExtractAadGroupId/StripClaims declared internal to enable unit testing via InternalsVisibleTo without polluting public API
-- [Phase 01-foundation]: MsalClientFactory stores MsalCacheHelper per clientId and exposes GetCacheHelper() — PnP creates its own internal PCA so tokenCacheCallback is the bridge for shared persistent cache
+- [Phase 17]: Graph client created lazily on first AAD group encountered to avoid unnecessary auth overhead for groups with no nested AAD members
-- [Phase 01-foundation]: SessionManager is the single holder of ClientContext instances — callers must not store returned contexts
+- [Phase 17]: groupMembers optional param in HtmlExportService — null produces identical pre-Phase-17 output; ISharePointGroupResolver injected as optional last param in PermissionsViewModel; resolution failure degrades gracefully with LogWarning
-- [Phase 01-foundation]: CacheDirectory is a constructor parameter (no-arg defaults to AppData) — enables test isolation without real filesystem writes
+- [Phase 18-auto-take-ownership]: OwnershipElevationService uses Tenant.SetSiteAdmin from PnP.Framework
-- [Phase 01-foundation]: Interactive login test marked Skip in unit suite — browser/WAM MSAL flow cannot run in automated CI
+- [Phase 18-auto-take-ownership]: WasAutoElevated last positional param with default=false preserves all existing PermissionEntry callsites
-- [Phase 01-foundation]: ObservableRecipient lambda receivers need explicit cast to FeatureViewModelBase for virtual dispatch
+- [Phase 18-auto-take-ownership]: AutoTakeOwnership ViewModel setter uses fire-and-forget pattern matching DataFolder
-- [Phase 01-foundation]: FeatureViewModelBase declared as abstract partial class — CommunityToolkit.Mvvm source generator requires partial keyword
+- [Phase 18-auto-take-ownership]: Toggle read before scan loop (not in exception filter) — await in when clause unsupported; pre-read bool preserves semantics
-- [Phase 01-foundation]: OpenFolderDialog (Microsoft.Win32) used in WPF instead of FolderBrowserDialog (System.Windows.Forms)
+- [Phase 18-auto-take-ownership]: WasAutoElevated DataTrigger last in RowStyle.Triggers — amber wins over RiskLevel color
-- [Phase 01-foundation]: LogPanel exposed via GetLogPanel() method — x:Name generates field in XAML partial class, property with same name causes CS0102
+- [Phase 19-app-registration-removal]: AppRegistrationService uses AppGraphClientFactory alias to disambiguate from Microsoft.Graph.GraphClientFactory
-- [Phase 01-foundation]: ProfileManagementViewModel dialog factory pattern — ViewModel exposes Func<Window>? OpenProfileManagementDialog set by View layer; avoids Window/DI coupling in ViewModel
+- [Phase 19-app-registration-removal]: BuildRequiredResourceAccess declared internal to enable direct unit testing without live Graph calls
-- [Phase 01-foundation]: IServiceProvider injected into MainWindow constructor — resolves DI-registered ProfileManagementDialog and SettingsView at runtime
+- [Phase 19-app-registration-removal]: SharePoint AllSites.FullControl GUID marked LOW confidence — must be verified against live tenant
-- [Phase 01-foundation]: ProfileManagementDialog and SettingsView registered as Transient — fresh instance with fresh ViewModel per dialog open or tab init
+- [Phase 19-app-registration-removal]: ProfileManagementViewModel constructor gains IAppRegistrationService as last param — existing logo tests updated to 5-param
-- [Phase 01-foundation]: Solution file is .slnx (not .sln) — dotnet build/test commands must use SharepointToolbox.slnx
+- [Phase 19-app-registration-removal]: TranslationSource.Instance used directly in ViewModel for status strings (consistent with runtime locale switching)
-- [Phase 01-foundation]: 45 tests total: 44 pass, 1 skip (interactive MSAL GetOrCreateContextAsync_CreatesContext — browser/WAM flow excluded from automated suite)
+- [Phase 19-app-registration-removal]: BooleanToVisibilityConverter declared in Window.Resources (WPF built-in, no custom converter needed)
-- [Phase 02-permissions]: DeriveAdminUrl is internal static — enables direct unit testing of admin URL regex without live tenant
-- [Phase 02-permissions]: InternalsVisibleTo added to AssemblyInfo.cs — required for test project to access internal DeriveAdminUrl; plan omitted this assembly attribute
-- [Phase 02-permissions]: Export service stubs created in Plan 02-01 so test project compiles before Plan 03 implementation
-- [Phase 02-permissions]: Principal.Email removed from CSOM load expression — Email only exists on User subtype, not Principal base class
-- [Phase 02-permissions]: Folder is not a SecurableObject in CSOM — ListItem used for permission extraction — Required by CSOM type system; Folder inherits from ClientObject not SecurableObject
-- [Phase 02-permissions]: Principal.Email excluded from CSOM Include — email not needed for PermissionEntry — Principal base type has no Email property; only User subtype does; avoids CS1061
-- [Phase 02-permissions]: CsvExportService uses UTF-8 with BOM for Excel compatibility; HtmlExportService uses UTF-8 without BOM
-- [Phase 02-permissions]: ISessionManager interface extracted from concrete SessionManager — required for Moq-based unit testing of PermissionsViewModel
-- [Phase 02-permissions]: PermissionsView code-behind wires Func<TenantProfile, SitePickerDialog> factory via DI — avoids Window coupling in ViewModel, keeps ViewModel testable
-- [Phase 02-permissions]: ISessionManager -> SessionManager DI registration was missing from App.xaml.cs — added in plan 02-07 (auto-detected Rule 3 blocker)
-- [Phase 02-permissions]: MainWindow.xaml uses x:Name on Permissions TabItem; MainWindow.xaml.cs sets Content at runtime from DI — same pattern as SettingsView
-- [Phase 03-storage]: Storage display uses flat DataGrid with IndentLevel -> Margin IValueConverter (not WPF TreeView) — better UI virtualization for large sites
-- [Phase 03-storage]: StorageNode.VersionSizeBytes is a derived property (TotalSizeBytes - FileStreamSizeBytes, Math.Max 0) — not stored separately
-- [Phase 03-storage]: SearchService uses KeywordQuery + SearchExecutor (Microsoft.SharePoint.Client.Search.Query) — transitive dep of PnP.Framework; no new NuGet package
-- [Phase 03-storage]: Search pagination: StartRow += 500, hard cap StartRow <= 50,000 (SharePoint Search boundary) = 50,000 max results
-- [Phase 03-storage]: DuplicatesService uses CAML FSObjType=1 (not FileSystemObjectType) for folder queries — wrong name returns zero results silently
-- [Phase 03-storage]: Duplicate detection uses composite key grouping (name+size+dates), no content hashing — matches PS reference and DUPL-01/02/03 requirements exactly
-- [Phase 03-storage]: Phase 3 export services are separate classes from Phase 2 (StorageCsvExportService, SearchCsvExportService, etc.) — different schemas
-- [Phase 03-storage]: StorageNode.VersionSizeBytes is a derived property (Math.Max(0, TotalSizeBytes - FileStreamSizeBytes)) — not stored separately
-- [Phase 03-storage]: MakeKey composite key logic tested inline in DuplicatesServiceTests before Plan 03-04 creates the real class — avoids skipping all duplicate logic tests
-- [Phase 03-storage]: Export service stubs return string.Empty until implemented — compile-only skeletons for Plans 03-03 and 03-05
-- [Phase 03-storage 03-02]: StorageService.LastModified uses StorageMetrics.LastModified with fallback to Folder.TimeLastModified — StorageMetrics.LastModified may be DateTime.MinValue for empty libraries
-- [Phase 03-storage 03-02]: System folder filter uses Forms/ and _-prefix heuristic — matches SharePoint standard hidden folder naming convention
-- [Phase 03-storage]: Explicit System.IO using required in StorageCsvExportService and StorageHtmlExportService — WPF project does not include System.IO in implicit usings (established project pattern)
-- [Phase 03-storage 03-04]: SearchService uses SelectProperties.Add per-item loop — StringCollection has no AddRange(string[]) overload in this SDK version
-- [Phase 03-storage 03-04]: DuplicatesService.MakeKey internal static method matches inline test helper in DuplicatesServiceTests exactly — deliberate design to ensure test parity
-- [Phase 03-storage 03-04]: DuplicatesService file mode re-implements pagination inline — avoids coupling between services with different result models (DuplicateItem vs SearchResult)
-- [Phase 03-storage]: ClientContext.Url is read-only in CSOM — site URL override done via new TenantProfile with site URL for GetOrCreateContextAsync
-- [Phase 03-storage]: IndentConverter/BytesConverter/InverseBoolConverter registered in App.xaml Application.Resources — accessible to all views without per-UserControl declaration
-- [Phase 03-storage]: SearchCsvExportService uses UTF-8 BOM for Excel compatibility — consistent with Phase 2 CsvExportService pattern
-- [Phase 03-storage]: DuplicatesHtmlExportService always uses badge-dup (red) for all groups — ok/diff distinction removed from final DUPL-03 spec
-- [Phase 03]: SearchViewModel and DuplicatesViewModel use TenantProfile site URL override pattern — ctx.Url is read-only in CSOM (established pattern from StorageViewModel)
-- [Phase 03]: DuplicateRow flat DTO wraps DuplicateItem with GroupName and GroupSize for DataGrid display
-- [Phase 04-bulk-operations-and-provisioning]: ITemplateService uses ModelSiteTemplate alias — SiteTemplate is ambiguous between SharepointToolbox.Core.Models and Microsoft.SharePoint.Client; resolved with using alias
-- [Phase 04-bulk-operations-and-provisioning]: ICsvValidationService and BulkResultCsvExportService require explicit System.IO using — WPF project does not include System.IO in implicit usings (established project pattern)
-- [Phase 04-bulk-operations-and-provisioning]: BulkSiteService uses Core.Helpers.ExecuteQueryRetryHelper not Infrastructure.Auth — plan had wrong using; correct namespace is Core.Helpers (established pattern from Phase 2/3 services)
-- [Phase 04-bulk-operations-and-provisioning]: Design-time MSBuild compile used for build verification — dotnet build WinFX BAML step fails in bash shell; C# compilation verified via dotnet msbuild -t:Compile -p:DesignTimeBuild=true with 0 errors; DLL-based test run confirms 4 pass / 3 skip
-- [Phase 04-bulk-operations-and-provisioning]: CsvValidationService uses DetectDelimiter=true — handles both comma and semicolon CSV files without format-specific code paths
-- [Phase 04-bulk-operations-and-provisioning]: TemplateRepository uses same atomic write pattern as SettingsRepository (tmp + File.Move + round-trip JSON validation)
-- [Phase 04-bulk-operations-and-provisioning 04-04]: GraphClientFactory uses GetOrCreateAsync (async) — MsalClientFactory only exposes async method with SemaphoreSlim locking; plan had incorrect sync reference GetOrCreateClient
-- [Phase 04-bulk-operations-and-provisioning 04-04]: AuthGraphClientFactory alias resolves CS0104 — Microsoft.Graph.GraphClientFactory conflicts with SharepointToolbox.Infrastructure.Auth.GraphClientFactory when both namespaces imported
-- [Phase 04-bulk-operations-and-provisioning 04-04]: Microsoft.SharePoint.Client.Group? fully qualified in AddToClassicGroupAsync — Microsoft.Graph.Models.Group also in scope in BulkMemberService; explicit namespace resolves ambiguity
-- [Phase 04-bulk-operations-and-provisioning]: TemplateService uses ModelSiteTemplate alias — consistent with ITemplateService; CSOM SiteTemplate and Core.Models.SiteTemplate are both in scope
-- [Phase 04-bulk-operations-and-provisioning]: FolderStructureService.BuildUniquePaths sorts by slash count for parent-first ordering — ensures intermediate folders exist before children when using Folders.Add
-- [Phase 04-bulk-operations-and-provisioning]: TemplateService.ApplyTemplateAsync creates new ClientContext for new site URL — adminCtx.Url points to admin site, new site needs separate context
-- [Phase 04-bulk-operations-and-provisioning]: FolderBrowserDialog uses Core.Helpers.ExecuteQueryRetryHelper (not Infrastructure.Auth) — consistent with established project namespace pattern
-- [Phase 04-bulk-operations-and-provisioning]: Example CSV files placed in Resources/ and registered as EmbeddedResource — accessible via Assembly.GetManifestResourceStream without file system dependency
-- [Phase 04-bulk-operations-and-provisioning]: SitePickerDialog.SelectedUrls.FirstOrDefault() used for single-site transfer selection — avoids new dialog variant while reusing existing dialog
-- [Phase 04-bulk-operations-and-provisioning]: EnumBoolConverter added for RadioButton-to-enum binding (TransferMode); ConverterParameter=EnumValueName pattern established for future ViewModels
-- [Phase 04-bulk-operations-and-provisioning 04-09]: BulkMembersViewModel passes _currentProfile.ClientId to AddMembersAsync — IBulkMemberService interface requires clientId for Graph API authentication; plan code omitted this parameter
-- [Phase 04-bulk-operations-and-provisioning 04-09]: Duplicate standalone converter files (EnumBoolConverter.cs etc.) removed — already defined in IndentConverter.cs which is the established project pattern for all converters
-- [Phase 04-bulk-operations-and-provisioning]: TemplatesView uses RenameInputDialog (custom WPF Window) instead of Microsoft.VisualBasic.Interaction.InputBox — avoids additional framework dependency
-- [Phase 04-bulk-operations-and-provisioning]: All value converters (EnumBoolConverter, StringToVisibilityConverter, ListToStringConverter) added to IndentConverter.cs — consistent co-location pattern
-- [Phase 05-distribution-and-hardening]: PublishSingleFile PropertyGroup is conditional on '' == 'true' — regular dotnet build and dotnet test are unaffected
-- [Phase 05-distribution-and-hardening]: IncludeNativeLibrariesForSelfExtract=true required — PnP.Framework has native binaries that must bundle into the EXE
-- [Phase 05-distribution-and-hardening]: IsThrottleException only checks top-level Message (not InnerException) — documented via nested-throttle test asserting false
-- [Phase 05-distribution-and-hardening]: FR diacritics already present in Strings.fr.resx — FrStrings_ContainExpectedDiacritics test passes immediately (no diacritic repair needed for those 5 keys)
 
 ### Pending Todos
 
-None yet.
+None.
 
 ### Blockers/Concerns
 
-- Phase 4 planning: PnP Provisioning Engine behavior for Teams-connected modern sites — edge cases need validation spike before planning
+None.
-- Phase 5: User access export (v2 requirement UACC-01/02) depends on Phase 2 PermissionsService — confirm scope before Phase 5 planning

+
+## Current Focus
+
+hypothesis: ROOT CAUSE CONFIRMED — two bugs in SiteListService.GetSitesAsync
+test: code reading confirmed via PnP source
+expecting: fixing both issues will resolve the error
+next_action: apply fix to SiteListService.cs
+
+## Symptoms
+
+expected: After connecting to a SharePoint tenant (https://contoso.sharepoint.com format), clicking "Select Sites" opens SitePickerDialog and loads the list of tenant sites.
+actual: SitePickerDialog opens but shows error "Must specify valid information for parsing in the string" instead of loading sites.
+errors: "Must specify valid information for parsing in the string" — this is an ArgumentException thrown by CSOM when it tries to parse an empty string as a site URL cursor
+reproduction: 1) Launch app 2) Add profile with valid tenant URL 3) Connect 4) Authenticate 5) Click Select Sites 6) Error appears in StatusText
+started: First time testing this flow after Phase 6 wiring was added.
+
+## Eliminated
+
+- hypothesis: Error comes from PnP's AuthenticationManager.GetContextAsync URI parsing
+  evidence: GetContextAsync line 1090 does new Uri(siteUrl) which is valid for "https://contoso-admin.sharepoint.com"
+  timestamp: 2026-04-07
+
+- hypothesis: Error from MSAL constructing auth URL with empty component
+  evidence: MSAL uses organizations authority or tenant-specific, both valid; no empty strings involved
+  timestamp: 2026-04-07
+
+- hypothesis: UriFormatException from new Uri("") in our own code
+  evidence: No Uri.Parse or new Uri() calls in SiteListService or SessionManager
+  timestamp: 2026-04-07
+
+## Evidence
+
+- timestamp: 2026-04-07
+  checked: PnP Framework 1.18.0 GetContextAsync source (line 1090)
+  found: Calls new Uri(siteUrl) — valid for admin URL
+  implication: Error not from GetContextAsync itself
+
+- timestamp: 2026-04-07
+  checked: PnP TenantExtensions.GetSiteCollections source
+  found: Uses GetSitePropertiesFromSharePointByFilters with StartIndex = null (for first page); OLD commented-out approach used GetSitePropertiesFromSharePoint(null, includeDetail) — note: null, not ""
+  implication: SiteListService passes "" which is wrong — should be null for first page
+
+- timestamp: 2026-04-07
+  checked: Error message "Must specify valid information for parsing in the string"
+  found: This is ArgumentException thrown by Enum.Parse or string cursor parsing when given "" (empty string); CSOM's GetSitePropertiesFromSharePoint internally parses the startIndex string as a URL/cursor; passing "" triggers parse failure
+  implication: Direct cause of exception confirmed
+
+- timestamp: 2026-04-07
+  checked: How PnP creates admin context from regular context
+  found: PnP uses clientContext.Clone(adminSiteUrl) — clones existing authenticated context to admin URL without triggering new auth flow
+  implication: SiteListService creates a SECOND AuthenticationManager and triggers second interactive login unnecessarily; should use Clone instead
+
+## Resolution
+
+root_cause: |
+  SiteListService.GetSitesAsync has two bugs:
+  
+  BUG 1 (direct cause of error): Line 50 calls tenant.GetSitePropertiesFromSharePoint("", true)
+  with empty string "". CSOM expects null for the first page (no previous cursor), not "".
+  Passing "" causes CSOM to attempt parsing it as a URL cursor, throwing
+  ArgumentException: "Must specify valid information for parsing in the string."
+  
+  BUG 2 (design problem): GetSitesAsync creates a separate TenantProfile for the admin URL
+  and calls SessionManager.GetOrCreateContextAsync(adminProfile) which creates a NEW
+  AuthenticationManager with interactive login. This triggers a SECOND browser auth flow
+  just to access the admin URL. The correct approach is to clone the existing authenticated
+  context to the admin URL using clientContext.Clone(adminUrl), which reuses the same tokens.
+
+fix: |
+  1. Replace GetOrCreateContextAsync(adminProfile) with GetOrCreateContextAsync(profile) to 
+     get the regular context, then clone it to the admin URL.
+  2. Replace GetSitePropertiesFromSharePointByFilters with proper pagination (StartIndex=null).
+  
+  The admin URL context is obtained via: adminCtx = ctx.Clone(adminUrl)
+  The site listing uses: GetSitePropertiesFromSharePointByFilters with proper filter object.
+
+verification: |
+  Build succeeds (0 errors). 144 tests pass, 0 failures.
+  Fix addresses both root causes:
+  1. No longer calls GetOrCreateContextAsync with admin profile — uses Clone() instead
+  2. Uses GetSitePropertiesFromSharePointByFilters (modern API) instead of GetSitePropertiesFromSharePoint("")

+# Milestone Audit: SharePoint Toolbox v2 — v1 Release
+
+**Audited:** 2026-04-07
+**Milestone:** v1 (5 phases, 42 requirements)
+**Verdict:** PASSED — all requirements satisfied, all phases integrated, build and tests green
+
+---
+
+## Phase Verification Summary
+
+| Phase | Status | Score | Verification |
+|-------|--------|-------|-------------|
+| 01 — Foundation | PASSED | 11/11 | 01-VERIFICATION.md |
+| 02 — Permissions | HUMAN_NEEDED | 7/7 automated | 02-VERIFICATION.md (2 human items pending) |
+| 03 — Storage & File Ops | **MISSING** | No VERIFICATION.md | Summaries exist for all 8 plans; integration checker confirmed all wiring |
+| 04 — Bulk Ops & Provisioning | HUMAN_NEEDED | 12/12 automated | 04-VERIFICATION.md (7 human items pending) |
+| 05 — Distribution & Hardening | HUMAN_NEEDED | 6/6 automated | 05-VERIFICATION.md (2 human items pending) |
+
+### Gap: Phase 03 Missing Verification
+
+Phase 03 has no `03-VERIFICATION.md` file. All 8 plan summaries exist and confirm code was delivered. The integration checker independently verified:
+- All 3 Phase 3 service interfaces (IStorageService, ISearchService, IDuplicatesService) registered in DI
+- All 5 export services registered and wired to ViewModels
+- All 4 Phase 3 tabs (Storage, Search, Duplicates + exports) wired in MainWindow
+- 13 Phase 3 requirements (STOR-01–05, SRCH-01–04, DUPL-01–03) covered
+
+**Recommendation:** Run a retroactive phase verification for Phase 03 or accept integration checker evidence as sufficient.

+## Cross-Phase Integration
+
+Integration checker ran full verification. Results:
+
+| Check | Status |
+|-------|--------|
+| DI wiring (all 5 phases) | PASS — all services registered in App.xaml.cs |
+| MainWindow tabs (10 tabs) | PASS — all declared and wired from DI |
+| FeatureViewModelBase inheritance (10 VMs) | PASS |
+| SessionManager usage (9 ViewModels + SiteListService) | PASS |
+| ExecuteQueryRetryHelper (9 CSOM services, 40+ call sites) | PASS |
+| SharePointPaginationHelper (2 services using list enumeration) | PASS |
+| TranslationSource localization (15 XAML files, 170 bindings) | PASS |
+| TenantSwitchedMessage propagation | PASS |
+| Export chain completeness (all features) | PASS |
+| Build | PASS — 0 warnings, 0 errors |
+| Tests | PASS — 134 passed, 22 skipped (live CSOM), 0 failed |
+| EN/FR key parity | PASS — 199/199 keys |
+
+**Orphaned code:** `FeatureTabBase.xaml` — Phase 1 placeholder, now superseded by full tab views. Harmless dead code.
+
+---
+
+## Tech Debt & Deferred Items
+
+### From Phase Verifications
+
+| Item | Source | Severity | Description |
+|------|--------|----------|-------------|
+| Hardcoded export button text | Phase 2 | Info | `PermissionsView.xaml` uses `Content="Export CSV"` / `"Export HTML"` instead of `rad.csv.perms` / `rad.html.perms` localization keys. French users see English button labels. |
+| Missing Designer.cs property | Phase 2 | Info | `Strings.Designer.cs` lacks `tab_permissions` typed accessor. Runtime binding via `TranslationSource` works fine. |
+| No invalid-row highlighting | Phase 4 | Warning | `BulkMembersView.xaml`, `BulkSitesView.xaml`, `FolderStructureView.xaml` show IsValid as text column but lack `RowStyle` + `DataTrigger` for visual red highlighting on invalid rows. |
+| FeatureTabBase dead code | Phase 1→all | Info | `Views/Controls/FeatureTabBase.xaml` is no longer imported by any tab view after all phases replaced stubs. |
+| Cancel test locale mismatch | Phase 3 (03-08) | Info | `FeatureViewModelBaseTests.CancelCommand_DuringOperation_SetsStatusMessageToCancelled` asserts `.Contains("cancel")` but app returns French string "Opération annulée". Pre-existing; deferred. |
+
+### Deferred v2 Requirements
+
+These are explicitly out of scope for v1 and tracked in REQUIREMENTS.md:
+- UACC-01/02: User access audit across sites
+- SIMP-01/02/03: Simplified plain-language permission reports
+- VIZZ-01/02/03: Storage metrics graphs (pie/bar chart)
+
+---
+
+## Human Verification Backlog
+
+11 items across 3 phases require human confirmation (runtime UI/locale checks that cannot be automated):
+
+### Phase 2 (2 items)
+1. Full Permissions tab UI visual checkpoint (layout, disabled states, French locale)
+2. Export button localization decision (accept hardcoded English or bind to resx keys)
+
+### Phase 4 (7 items)
+1. Application launches with all 10 tabs visible
+2. Bulk Members — Load Example populates DataGrid with 7 rows
+3. Bulk Sites — semicolon CSV auto-detection works
+4. Invalid row display in DataGrid (IsValid=False, Errors column)
+5. Confirmation dialog appears before bulk operations
+6. Transfer tab — two-step browse flow (SitePickerDialog → FolderBrowserDialog)
+7. Templates tab — 5 capture checkboxes visible and checked by default
+
+### Phase 5 (2 items)
+1. Clean-machine EXE launch (no .NET runtime installed)
+2. French locale runtime rendering (diacritics display correctly in all tabs)
+
+---
+
+## Build & Test Summary
+
+| Metric | Value |
+|--------|-------|
+| Build | 0 errors, 0 warnings |
+| Tests passed | 134 |
+| Tests skipped | 22 (live CSOM — expected) |
+| Tests failed | 0 |
+| EN locale keys | 199 |
+| FR locale keys | 199 |
+| Published EXE | 200.9 MB self-contained |
+| Phases complete | 5/5 |
+| Requirements satisfied | 42/42 |
+
+---
+
+## Verdict
+
+**PASSED** — The milestone has achieved its definition of done:
+
+1. All 42 v1 requirements are implemented with real code and verified by phase-level checks
+2. All cross-phase integration points are wired (DI, messaging, shared infrastructure)
+3. Build compiles cleanly with zero warnings
+4. 134 automated tests pass with zero failures
+5. Self-contained 200.9 MB EXE produced successfully
+6. Full EN/FR locale parity (199 keys each)
+
+**Remaining actions before shipping:**
+- [ ] Complete 11 human verification items (UI visual checks, clean-machine launch)
+- [ ] Decide on Phase 03 retroactive verification (or accept integration check as sufficient)
+- [ ] Address 3 Warning-level tech debt items (invalid-row highlighting in bulk DataGrids)
+- [ ] Optionally clean up FeatureTabBase dead code and fix cancel test locale mismatch

+## Out of Scope
+
+| Feature | Reason |
+|---------|--------|
+| Cross-platform (Mac/Linux) | WPF is Windows-only; not justified for current user base |
+| Real-time monitoring / alerts | Requires background service, webhooks — turns desktop tool into a service |
+| Automated remediation (auto-revoke) | Liability risk; one wrong rule destroys client access |
+| SQLite / database storage | Breaks single-EXE distribution; JSON sufficient |
+| Cloud sync / shared profiles | Requires server infrastructure — out of scope for local tool |
+| AI-powered recommendations | Competes with Microsoft's own Copilot roadmap |
+| Content migration between tenants | Separate product category (ShareGate territory) |
+| Mobile app | Desktop admin tool |
+| OAuth with client secrets/certificates | Interactive login only — no stored credentials |
+| Version history management | Deep separate problem; surface totals in storage metrics only |

+# Roadmap: SharePoint Toolbox v2
+
+## Overview
+
+A full C#/WPF rewrite of a 6,400-line PowerShell-based SharePoint Online administration tool. The
+project delivers a self-contained Windows desktop application that lets MSP administrators audit
+and manage permissions, storage, and site provisioning across multiple client tenants from a single
+tool. Foundation infrastructure (multi-tenant auth, async patterns, error handling, DI) must be
+solid before any feature work begins — all 10 identified pitfalls in the existing codebase map
+entirely to Phase 1. Subsequent phases deliver complete, verifiable feature areas in dependency
+order: permissions first (validates auth and pagination), then storage and search (reuse those
+patterns), then bulk and provisioning operations (highest write-risk features last), then
+hardening and packaging.
+
+## Phases
+
+**Phase Numbering:**
+- Integer phases (1, 2, 3): Planned milestone work
+- Decimal phases (2.1, 2.2): Urgent insertions (marked with INSERTED)
+
+Decimal phases appear between their surrounding integers in numeric order.
+
+- [x] **Phase 1: Foundation** - WPF shell, multi-tenant auth, DI, async patterns, error handling, logging, localization, JSON persistence (completed 2026-04-02)
+- [x] **Phase 2: Permissions** - Permissions scan (single and multi-site), CSV and HTML report export
+- [x] **Phase 3: Storage and File Operations** - Storage metrics, file search, and duplicate detection (completed 2026-04-02)
+- [x] **Phase 4: Bulk Operations and Provisioning** - Bulk member/site/transfer operations, site templates, folder structure provisioning (completed 2026-04-03)
+- [x] **Phase 5: Distribution and Hardening** - Self-contained EXE packaging, end-to-end validation, FR locale completeness (completed 2026-04-03)
+
+## Phase Details
+
+### Phase 1: Foundation
+**Goal**: The application shell runs, users can authenticate to multiple tenants and switch between them without re-logging in, all long-running operations are cancellable and report progress, all errors surface visibly, and the infrastructure patterns that prevent the existing app's 10 known pitfalls are in place before any feature work begins.
+**Depends on**: Nothing (first phase)
+**Requirements**: FOUND-01, FOUND-02, FOUND-03, FOUND-04, FOUND-05, FOUND-06, FOUND-07, FOUND-08, FOUND-09, FOUND-10, FOUND-12
+**Success Criteria** (what must be TRUE):
+  1. User can create, rename, delete, and switch between tenant profiles via the UI — each profile stores tenant URL, client ID, and display name in a JSON file
+  2. User can authenticate to a tenant via interactive browser login and the session persists across tenant switches without re-entering credentials (MSAL token cache per tenant)
+  3. User can see real-time progress on any long-running operation and cancel it mid-execution with a button — the operation stops cleanly with no silent continuation
+  4. When any operation fails, the user sees an actionable error message in the UI — no operation fails silently or swallows an exception
+  5. UI language switches between English and French dynamically without restarting the application

+
+### Phase 2: Permissions
+**Goal**: Users can scan SharePoint permissions on one or many sites and export the results as both a raw CSV and a sortable, filterable HTML report — with no silent failures on large libraries and full control over scan scope.
+**Depends on**: Phase 1
+**Requirements**: PERM-01, PERM-02, PERM-03, PERM-04, PERM-05, PERM-06, PERM-07
+**Success Criteria** (what must be TRUE):
+  1. User can select one site or multiple sites and run a permissions scan that returns owners, members, guests, external users, and broken inheritance items
+  2. User can choose configurable scan depth and whether to include or exclude inherited permissions before running
+  3. User can export the permissions results to a CSV file with all raw permission data
+  4. User can export the permissions results to an interactive HTML report where rows are sortable, filterable, and groupable by user
+  5. Scanning a library with more than 5,000 items completes successfully — the tool paginates automatically and does not silently truncate or fail
+**Plans**: 7 plans
+
+Plans:
+- [x] 02-01-PLAN.md — Wave 0: test scaffolds (PermissionsService, ViewModel, classification, CSV, HTML export tests) + PermissionEntryHelper
+- [x] 02-02-PLAN.md — Core models + PermissionsService scan engine (PermissionEntry, ScanOptions, IPermissionsService, PermissionsService)
+- [x] 02-03-PLAN.md — SiteListService: tenant admin site listing for multi-site picker (ISiteListService, SiteListService, SiteInfo)
+- [x] 02-04-PLAN.md — Export services: CsvExportService (with row merging) + HtmlExportService (self-contained HTML)
+- [x] 02-05-PLAN.md — Localization: 15 Phase 2 EN/FR keys in Strings.resx, Strings.fr.resx, Strings.Designer.cs
+- [x] 02-06-PLAN.md — PermissionsViewModel + SitePickerDialog (XAML + code-behind)
+- [x] 02-07-PLAN.md — DI wiring + PermissionsView XAML + MainWindow tab replacement + visual checkpoint
+
+### Phase 3: Storage and File Operations
+**Goal**: Users can view and export storage metrics per site and library, search for files across sites using multiple criteria, and detect duplicate files and folders — all with consistent export options and no silent failures on large datasets.
+**Depends on**: Phase 2
+**Requirements**: STOR-01, STOR-02, STOR-03, STOR-04, STOR-05, SRCH-01, SRCH-02, SRCH-03, SRCH-04, DUPL-01, DUPL-02, DUPL-03
+**Success Criteria** (what must be TRUE):
+  1. User can view storage consumption per library and per site (with configurable folder depth), including total size, version size, item count, and last modified date
+  2. User can export storage metrics to CSV and to an interactive HTML with a collapsible tree view
+  3. User can search for files across sites using at least extension, name/regex, date range, creator, and editor as criteria — with a configurable result cap up to 50,000 items
+  4. User can export file search results to CSV and to an interactive sortable/filterable HTML
+  5. User can scan for duplicate files (by name, size, creation date, modification date) and duplicate folders (by name, subfolder count, file count) and export the results to an HTML with grouped display
+**Plans**: 8 plans
+
+Plans:
+- [ ] 03-01-PLAN.md — Wave 0: test scaffolds + models (StorageNode, SearchResult, DuplicateGroup/Item, options) + interfaces (IStorageService, ISearchService, IDuplicatesService) + export stubs
+- [ ] 03-02-PLAN.md — StorageService: CSOM StorageMetrics scan engine (recursive folder tree, library-level aggregation)
+- [ ] 03-03-PLAN.md — Storage export services: StorageCsvExportService + StorageHtmlExportService (collapsible tree HTML)
+- [ ] 03-04-PLAN.md — SearchService (KQL pagination, client-side Regex) + DuplicatesService (composite key grouping, CAML folder scan)
+- [ ] 03-05-PLAN.md — Search and Duplicate export services: SearchCsvExportService + SearchHtmlExportService + DuplicatesHtmlExportService
+- [ ] 03-06-PLAN.md — Localization: all Phase 3 EN/FR keys for Storage, File Search, and Duplicates tabs
+- [ ] 03-07-PLAN.md — StorageViewModel + StorageView XAML + DI wiring (Storage tab replaces FeatureTabBase stub)
+- [ ] 03-08-PLAN.md — SearchViewModel + SearchView + DuplicatesViewModel + DuplicatesView + DI wiring + visual checkpoint
+
+### Phase 4: Bulk Operations and Provisioning
+**Goal**: Users can execute bulk write operations (member additions, site creation, file transfer) with per-item error reporting and cancellation, capture site structures as reusable templates, apply templates to create new sites, and provision folder structures from CSV — all without silent partial failures.
+**Depends on**: Phase 3
+**Requirements**: BULK-01, BULK-02, BULK-03, BULK-04, BULK-05, TMPL-01, TMPL-02, TMPL-03, TMPL-04, FOLD-01, FOLD-02
+**Success Criteria** (what must be TRUE):
+  1. User can transfer files and folders between sites with real-time progress tracking and can cancel mid-operation — transferred items are confirmed and failures are reported per-item
+  2. User can add members to groups in bulk from a CSV file — each row that fails is reported individually, not silently skipped
+  3. User can create multiple sites in bulk from a CSV file with per-site error reporting and mid-operation cancellation
+  4. User can capture an existing site's structure (libraries, folders, permission groups, logo, settings) as a named template stored in JSON, then apply that template to create a new Communication or Teams site
+  5. User can manage saved templates (create, rename, delete) and create folder structures on a target site from a CSV template
+**Plans**: 10 plans
+
+Plans:
+- [ ] 04-01-PLAN.md — Dependencies + core models + interfaces + BulkOperationRunner + test scaffolds
+- [ ] 04-02-PLAN.md — CsvValidationService + TemplateRepository with unit tests
+- [ ] 04-03-PLAN.md — FileTransferService (CSOM MoveCopyUtil, conflict policies)
+- [ ] 04-04-PLAN.md — BulkMemberService (Graph SDK batch + CSOM fallback)
+- [ ] 04-05-PLAN.md — BulkSiteService (PnP Framework site creation)
+- [ ] 04-06-PLAN.md — TemplateService + FolderStructureService
+- [ ] 04-07-PLAN.md — Localization + shared dialogs + example CSV resources
+- [ ] 04-08-PLAN.md — TransferViewModel + TransferView
+- [ ] 04-09-PLAN.md — BulkMembersViewModel + BulkSitesViewModel + FolderStructureViewModel + Views
+- [ ] 04-10-PLAN.md — TemplatesViewModel + TemplatesView + DI registration + MainWindow wiring + visual checkpoint
+
+### Phase 5: Distribution and Hardening
+**Goal**: The application ships as a single self-contained EXE that runs on a machine with no .NET runtime installed, all previously identified reliability constraints are verified end-to-end (5,000-item pagination, JSON corruption recovery, throttling retry, cancellation), and the French locale is complete and tested.
+**Depends on**: Phase 4
+**Requirements**: FOUND-11
+**Success Criteria** (what must be TRUE):
+  1. Running the published EXE on a clean machine with no .NET runtime installed launches the application and all features function correctly
+  2. The application recovers gracefully when a SharePoint API call is throttled (429/503) — the user sees a retry progress message and the operation eventually completes or surfaces a clear failure
+  3. The French locale is complete for all UI strings — no English fallback text appears when the language is set to French
+  4. A scan against a library with more than 5,000 items returns complete, correct results with no silent truncation verified against a known dataset
+**Plans**: 3 plans
+
+Plans:
+- [ ] 05-01-PLAN.md — Helper visibility changes + retry/pagination/locale unit tests
+- [ ] 05-02-PLAN.md — FR diacritic corrections + self-contained publish configuration
+- [ ] 05-03-PLAN.md — Full test suite verification + publish smoke test + human checkpoint
