- File mode: Search API KQL pagination matching SearchService pattern
- Folder mode: CAML FSObjType=1 via SharePointPaginationHelper.GetAllItemsAsync
- MakeKey composite key (name+size+dates+counts) matches DuplicatesServiceTests scaffold
- Groups only items with count >= 2, ordered by group size then name
- ExtractLibraryFromPath derives library name from path relative to site URL
- SelectProperties added per-item (StringCollection has no AddRange)
- KQL builder for extension, date, creator, editor, library filters
- Pagination via StartRow += 500, stops at MaxStartRow or MaxResults
- Filters _vti_history/ version history paths from results
- Client-side Regex filter on file name and title
- ValidateKqlLength enforces 4096-char SharePoint limit
- SelectProperties added one-by-one (StringCollection has no AddRange)
- Replace string.Empty stub with full BuildHtml implementation
- Self-contained HTML with inline CSS and JS — no external dependencies
- toggle(i) JS function with collapsible subfolder rows (sf-{i} IDs)
- _togIdx counter reset at start of each BuildHtml call (per PS pattern)
- RenderNode/RenderChildNode for recursive tree rendering
- FormatSize helper: B/KB/MB/GB adaptive display
- HtmlEncode via System.Net.WebUtility
- Add explicit System.IO using (required in WPF project)
- Add StorageService implementing IStorageService
- Load Folder.StorageMetrics, TimeLastModified, Name, ServerRelativeUrl in one CSOM round-trip per folder
- CollectStorageAsync returns one StorageNode per document library at IndentLevel=0
- With FolderDepth>0, CollectSubfoldersAsync recurses into child folders
- All CSOM calls use ExecuteQueryRetryHelper.ExecuteQueryRetryAsync (3 call sites)
- System/hidden lists skipped (Hidden=true or BaseType != DocumentLibrary)
- Forms/ and _-prefixed system folders skipped during subfolder recursion
- ct.ThrowIfCancellationRequested() called at top of every recursive step
- Stats cards: Total Entries, Unique Permission Sets, Distinct Users/Groups
- Type badges: site-coll (blue), site (green), list (amber), folder (gray)
- Unique/Inherited badges based on HasUniquePermissions flag
- User pills with external-user CSS class for #EXT# logins
- Inline JS filterTable() function for client-side row filtering
- WriteAsync uses UTF-8 without BOM for HTML
- All 3 HtmlExportServiceTests pass
[Rule 3 - Blocking] CsvExportService/HtmlExportService stubs added so export test
files compile. [Rule 1 - Bug] PermissionsService: removed Principal.Email (not on
Principal, only on User) and changed folder param from Folder to ListItem (SecurableObject).
- Added 15 keys to Strings.resx with English values (grp.scan.opts, chk.scan.folders, chk.recursive, lbl.folder.depth, chk.max.depth, chk.inherited.perms, grp.export.fmt, rad.csv.perms, rad.html.perms, btn.gen.perms, btn.open.perms, btn.view.sites, perm.site.url, perm.or.select, perm.sites.selected)
- Added same 15 keys to Strings.fr.resx with genuine French translations (no English fallback)
- Added 15 static properties to Strings.Designer.cs following dot-to-underscore naming pattern
- SiteInfo record added to Core/Models
- ISiteListService interface with GetSitesAsync signature
- SiteListService derives admin URL via Regex, connects via SessionManager
- Filters to Active sites only, excludes OneDrive personal (-my.sharepoint.com)
- Access denied ServerException wrapped as InvalidOperationException with actionable message
- DeriveAdminUrl marked internal static for unit testability
- InternalsVisibleTo added to AssemblyInfo.cs to expose internal to test project
- 2 DeriveAdminUrl tests pass; full suite: 53 pass, 4 skip, 0 fail
- Create Views/Tabs/SettingsView.xaml (UserControl with language ComboBox en/fr, DataFolder TextBox and Browse button using TranslationSource)
- Create Views/Tabs/SettingsView.xaml.cs (DI constructor injection of SettingsViewModel, LoadAsync on Loaded)
- Update MainWindow.xaml to add xmlns:views namespace and clear placeholder TextBlock from SettingsTabItem
- Register SettingsView as Transient in DI; resolve and set as SettingsTabItem.Content from MainWindow constructor
- All 42 unit tests pass, 0 build errors
- Create Views/Dialogs/ProfileManagementDialog.xaml (modal Window with Name/TenantUrl/ClientId fields and TranslationSource bindings)
- Create Views/Dialogs/ProfileManagementDialog.xaml.cs (DI constructor injection, LoadAsync on Loaded)
- Add OpenProfileManagementDialog factory delegate to MainWindowViewModel
- Wire ManageProfilesCommand to open dialog via factory, reload profiles after close
- Register ProfileManagementDialog as Transient in DI (App.xaml.cs)
- Inject IServiceProvider into MainWindow constructor for DI-resolved dialog factory
- SessionManager owns all ClientContexts; callers must not store references
- IsAuthenticated(tenantUrl) returns false before auth, true after GetOrCreateContextAsync
- ClearSessionAsync disposes ClientContext and removes state (idempotent for unknown tenants)
- GetOrCreateContextAsync validates null/empty TenantUrl and ClientId (ArgumentException)
- MsalClientFactory.GetCacheHelper() added — exposes helper for PnP tokenCacheCallback wiring
- 8 unit tests pass, 1 interactive-login test skipped (integration-only)
- LoggingIntegrationTests: verifies Serilog writes rolling log file with correct content
- LogPanelSink structural smoke test: confirms type implements ILogEventSink
- App.xaml.cs: added comment for LogPanelSink DI registration deferred to plan 01-06
- SharePointPaginationHelper: async iterator with ListItemCollectionPosition loop (bypasses 5k limit); RowLimit=2000; [EnumeratorCancellation] for correct WithCancellation support
- ExecuteQueryRetryHelper: exponential backoff on 429/503/throttle; surfaces retry events via IProgress<OperationProgress>; max 5 retries
- LogPanelSink: custom Serilog ILogEventSink writing color-coded entries to RichTextBox via Dispatcher.InvokeAsync for thread safety
