 ## RECENT CHANGES (This Session)
 
+**Job Scheduler Race Condition Fix (Dec 8, 2025):**
+- ✅ **In-Memory Deduplication** - Added `HashSet<Guid>` to track LayerIds scheduled within the same batch
+- ✅ **Prevents Duplicate Jobs** - Fixed race condition where same layer could be scheduled multiple times during single "Run All Jobs" operation
+- ✅ **Two-Level Protection** - In-memory check (HashSet) runs before database check for O(1) performance
+- ✅ **Applied to Both Methods** - Fixed both ScheduleImportJobsAsync and ScheduleProcessJobsAsync
+- ✅ **Better Logging** - Added debug log message "Job already scheduled in this batch" for transparency
+- Root cause: When multiple layers had same ID in query results or import plugins created new layers during scheduling loop, database check couldn't detect duplicates added in same batch before SaveChangesAsync()
+- Solution: Track scheduled LayerIds in HashSet during loop iteration to prevent within-batch duplicates
+- Files modified: [JobSchedulerService.cs](DiunaBI.Infrastructure/Services/JobSchedulerService.cs)
+- Status: Race condition resolved, duplicate job creation prevented
+
+---
+
+**Blazor Server Reconnection UI Customization (Dec 8, 2025):**
+- ✅ **Custom Reconnection Modal** - Replaced default Blazor "Rejoin failed..." dialog with custom-styled modal
+- ✅ **Theme-Matched Styling** - Changed loader and button colors from blue to app's primary red (#e7163d) matching navbar
+- ✅ **Timer with Elapsed Seconds** - Added real-time timer showing elapsed reconnection time (0s, 1s, 2s...)
+- ✅ **CSS Classes Integration** - Used Blazor's built-in `.components-reconnect-show/failed/rejected` classes for state management
+- ✅ **MutationObserver Timer** - JavaScript watches for CSS class changes to start/stop elapsed time counter
+- ✅ **Professional Design** - Modal backdrop blur, spinner animation, red reload button with hover effects
+- Files modified: [App.razor](DiunaBI.UI.Web/Components/App.razor), [app.css](DiunaBI.UI.Web/wwwroot/app.css)
+- Files created: [reconnect.js](DiunaBI.UI.Web/wwwroot/js/reconnect.js)
+- Status: Blazor reconnection UI now matches app theme with timer indicator
+
+**Jobs List Sorting and Multi-Select Filtering (Dec 8, 2025):**
+- ✅ **Fixed Job Sorting** - Changed from single CreatedAt DESC to Priority ASC → JobType → CreatedAt DESC
+- ✅ **Multi-Select Status Filter** - Replaced single status dropdown with multi-select supporting multiple JobStatus values
+- ✅ **Auto-Refresh on Filter Change** - Filters now automatically trigger data reload without requiring manual button click
+- ✅ **API Updates** - JobsController GetAll endpoint accepts `List<JobStatus>? statuses` instead of single status
+- ✅ **JobService Updates** - Sends status values as integers in query string for multi-select support
+- Files modified: [JobsController.cs](DiunaBI.API/Controllers/JobsController.cs), [JobService.cs](DiunaBI.UI.Shared/Services/JobService.cs), [Index.razor](DiunaBI.UI.Shared/Pages/Jobs/Index.razor), [Index.razor.cs](DiunaBI.UI.Shared/Pages/Jobs/Index.razor.cs)
+- Status: Jobs list now sortable by priority/type/date with working multi-select filters
+
+**User Timezone Support (Dec 8, 2025):**
+- ✅ **DateTimeHelper Service** - Created JS Interop service to detect user's browser timezone
+- ✅ **UTC to Local Conversion** - All date displays now show user's local timezone instead of UTC
+- ✅ **Database Consistency** - Database continues to store UTC (correct), conversion only for display
+- ✅ **Updated Pages** - Applied timezone conversion to all date fields in:
+  - Jobs Index and Details pages
+  - Layers Details page (CreatedAt, ModifiedAt, record history)
+  - DataInbox Index page
+- ✅ **Service Registration** - Registered DateTimeHelper as scoped service in DI container
+- Files created: [DateTimeHelper.cs](DiunaBI.UI.Shared/Services/DateTimeHelper.cs)
+- Files modified: [ServiceCollectionExtensions.cs](DiunaBI.UI.Shared/Extensions/ServiceCollectionExtensions.cs), [Jobs/Index.razor.cs](DiunaBI.UI.Shared/Pages/Jobs/Index.razor.cs), [Jobs/Details.razor](DiunaBI.UI.Shared/Pages/Jobs/Details.razor), [Layers/Details.razor](DiunaBI.UI.Shared/Pages/Layers/Details.razor), [Layers/Details.razor.cs](DiunaBI.UI.Shared/Pages/Layers/Details.razor.cs), [DataInbox/Index.razor.cs](DiunaBI.UI.Shared/Pages/DataInbox/Index.razor.cs)
+- Status: All dates display in user's local timezone with format "yyyy-MM-dd HH:mm:ss"
+
+**QueueJob Model Cleanup and AutoImport User (Dec 8, 2025):**
+- ✅ **Removed Duplicate Fields** - Removed CreatedAtUtc and ModifiedAtUtc from QueueJob (were duplicates of CreatedAt/ModifiedAt)
+- ✅ **Added ModifiedAt Field** - Was missing, now tracks job modification timestamp
+- ✅ **AutoImport User ID** - Created User.AutoImportUserId constant: `f392209e-123e-4651-a5a4-0b1d6cf9ff9d`
+- ✅ **System Operations** - All system-created/modified jobs now use AutoImportUserId for CreatedById and ModifiedById
+- ✅ **Database Migration** - Created migration: RemoveQueueJobDuplicateUTCFields
+- Files modified: [QueueJob.cs](DiunaBI.Domain/Entities/QueueJob.cs), [User.cs](DiunaBI.Domain/Entities/User.cs), [JobWorkerService.cs](DiunaBI.Infrastructure/Services/JobWorkerService.cs), [JobSchedulerService.cs](DiunaBI.Infrastructure/Services/JobSchedulerService.cs), [AppDbContext.cs](DiunaBI.Infrastructure/Data/AppDbContext.cs), [JobsController.cs](DiunaBI.API/Controllers/JobsController.cs)
+- Files created: [20251208205202_RemoveQueueJobDuplicateUTCFields.cs](DiunaBI.Infrastructure/Migrations/20251208205202_RemoveQueueJobDuplicateUTCFields.cs)
+- Status: QueueJob model cleaned up, all automated operations tracked with AutoImport user ID
+
+**Job Scheduling UI with JWT Authorization (Dec 8, 2025):**
+- ✅ **New JWT Endpoints** - Created UI-specific endpoints at `/jobs/ui/schedule/*` with JWT authorization (parallel to API key endpoints)
+- ✅ **Three Scheduling Options** - MudMenu dropdown in Jobs Index with:
+  - Run All Jobs - schedules all import and process jobs
+  - Run All Imports - schedules import jobs only
+  - Run All Processes - schedules process jobs only
+- ✅ **JobService Methods** - Added three scheduling methods returning (success, jobsCreated, message) tuples
+- ✅ **Auto-Refresh** - Jobs list automatically reloads after scheduling with success/failure notifications
+- ✅ **Dual Authorization** - Existing `/jobs/schedule/{apiKey}` endpoints for automation, new `/jobs/ui/schedule` endpoints for UI users
+- Files modified: [JobsController.cs](DiunaBI.API/Controllers/JobsController.cs), [JobService.cs](DiunaBI.UI.Shared/Services/JobService.cs), [Index.razor](DiunaBI.UI.Shared/Pages/Jobs/Index.razor), [Index.razor.cs](DiunaBI.UI.Shared/Pages/Jobs/Index.razor.cs)
+- Status: UI users can now schedule jobs directly from Jobs page using JWT authentication
+
+---
+
+**API Key Authorization Fix for Cron Jobs (Dec 6, 2025):**
+- ✅ **Fixed 401 Unauthorized on API Key Endpoints** - Cron jobs calling `/jobs/schedule` endpoints were getting rejected despite valid API keys
+- ✅ **Added [AllowAnonymous] Attribute** - Bypasses controller-level `[Authorize]` to allow `[ApiKeyAuth]` filter to handle authorization
+- ✅ **Three Endpoints Fixed** - Applied fix to all job scheduling endpoints:
+  - `POST /jobs/schedule` - Schedule all jobs (imports + processes)
+  - `POST /jobs/schedule/imports` - Schedule import jobs only
+  - `POST /jobs/schedule/processes` - Schedule process jobs only
+- Root cause: Controller-level `[Authorize]` attribute required JWT Bearer auth for all endpoints, blocking API key authentication
+- Solution: Add `[AllowAnonymous]` to allow `[ApiKeyAuth]` filter to validate X-API-Key header
+- Files modified: [JobsController.cs](DiunaBI.API/Controllers/JobsController.cs)
+- Status: Cron jobs can now authenticate with API key via X-API-Key header
+
+**SignalR Authentication Token Flow Fix (Dec 6, 2025):**
+- ✅ **TokenProvider Population** - Fixed `TokenProvider.Token` never being set with JWT, causing 401 Unauthorized on SignalR connections
+- ✅ **AuthService Token Management** - Injected `TokenProvider` into `AuthService` and set token in 3 key places:
+  - `ValidateWithBackendAsync()` - on fresh Google login
+  - `CheckAuthenticationAsync()` - on session restore from localStorage
+  - `ClearAuthenticationAsync()` - clear token on logout
+- ✅ **SignalR Initialization Timing** - Moved SignalR initialization from `MainLayout.OnInitializedAsync` to after authentication completes
+- ✅ **Event-Driven Architecture** - `MainLayout` now subscribes to `AuthenticationStateChanged` event to initialize SignalR when user authenticates
+- ✅ **Session Restore Support** - `CheckAuthenticationAsync()` now fires `AuthenticationStateChanged` event to initialize SignalR on page refresh
+- Root cause: SignalR was initialized before authentication, so JWT token was empty during connection setup
+- Solution: Initialize SignalR only after token is available via event subscription
+- Files modified: [AuthService.cs](DiunaBI.UI.Shared/Services/AuthService.cs), [MainLayout.razor](DiunaBI.UI.Shared/Components/Layout/MainLayout.razor)
+- Status: SignalR authentication working for both fresh login and restored sessions
+
+**SignalR Authentication DI Fix (Dec 6, 2025):**
+- ✅ **TokenProvider Registration** - Added missing `TokenProvider` service registration in DI container
+- ✅ **EntityChangeHubService Scope Fix** - Changed from singleton to scoped to support user-specific JWT tokens
+- ✅ **Bug Fix** - Resolved `InvalidOperationException` preventing app from starting after SignalR authentication was added
+- Root cause: Singleton service (`EntityChangeHubService`) cannot depend on scoped service (`TokenProvider`) in DI
+- Solution: Made `EntityChangeHubService` scoped so each user session has its own authenticated SignalR connection
+- Files modified: [ServiceCollectionExtensions.cs](DiunaBI.UI.Shared/Extensions/ServiceCollectionExtensions.cs)
+
+---
+
+**Security Audit & Hardening (Dec 5, 2025):**
+- ✅ **JWT Token Validation** - Enabled issuer/audience validation in [Program.cs](DiunaBI.API/Program.cs), fixed config key mismatch in [JwtTokenService.cs](DiunaBI.API/Services/JwtTokenService.cs)
+- ✅ **API Key Security** - Created [ApiKeyAuthAttribute.cs](DiunaBI.API/Attributes/ApiKeyAuthAttribute.cs) with X-API-Key header auth, constant-time comparison
+- ✅ **Job Endpoints** - Migrated 3 job scheduling endpoints in [JobsController.cs](DiunaBI.API/Controllers/JobsController.cs) from URL-based to header-based API keys
+- ✅ **Stack Trace Exposure** - Fixed 20 instances across 3 controllers ([JobsController.cs](DiunaBI.API/Controllers/JobsController.cs), [LayersController.cs](DiunaBI.API/Controllers/LayersController.cs), [DataInboxController.cs](DiunaBI.API/Controllers/DataInboxController.cs)) - now returns generic error messages
+- ✅ **SignalR Authentication** - Added [Authorize] to [EntityChangeHub.cs](DiunaBI.API/Hubs/EntityChangeHub.cs), configured JWT token in [EntityChangeHubService.cs](DiunaBI.UI.Shared/Services/EntityChangeHubService.cs)
+- ✅ **Rate Limiting** - Implemented ASP.NET Core rate limiting: 100 req/min general, 10 req/min auth in [Program.cs](DiunaBI.API/Program.cs)
+- ✅ **Security Headers** - Added XSS, clickjacking, MIME sniffing protection middleware in [Program.cs](DiunaBI.API/Program.cs)
+- ✅ **Input Validation** - Added pagination limits (1-1000) to GetAll endpoints in 3 controllers
+- ✅ **User Enumeration** - Fixed generic auth error in [GoogleAuthService.cs](DiunaBI.API/Services/GoogleAuthService.cs)
+- ✅ **Sensitive Data Logging** - Made conditional on development only in [Program.cs](DiunaBI.API/Program.cs)
+- ✅ **Base64 Size Limit** - Added 10MB limit to DataInbox in [DataInboxController.cs](DiunaBI.API/Controllers/DataInboxController.cs)
+- Files modified: 12 files (API: Program.cs, 4 controllers, 3 services, 1 hub, 1 new attribute; UI: EntityChangeHubService.cs, ServiceCollectionExtensions.cs)
+- Security status: 5/5 CRITICAL fixed, 3/3 HIGH fixed, 4/4 MEDIUM fixed
+
 **Seq Removal - Logging Cleanup (Dec 5, 2025):**
 - ✅ Removed Seq logging sink to eliminate commercial licensing concerns
 - ✅ Removed `Serilog.Sinks.Seq` NuGet package from DiunaBI.API.csproj
