Resolves #52 This Pull Request introduces the **NexusSearchBox** search feature with premium unified styling, implements a robust **dynamic Qdrant collection auto-provisioning and batch-vector ingestion pipeline**, integrates a unified **Serilog logging infrastructure** for the Blazor Hybrid environment (MAUI), and resolves the **401 Unauthorized API header propagation error** inside mobile builds. ### 🚀 Key Implementations #### 1. Premium `NexusSearchBox` & Semantic Search UI * **NexusSearchBox Component:** Created an elegant search-as-you-type search box with smooth key navigation, quick-clearing, and seamless dynamic styling. * **Unified Aesthetics:** Refactored the search box isolated styling to align perfectly with the dashboard's design system using glassmorphism, `--nexus-neon` token gradients, and smooth pulse/fade animations. * **Semantic Search Integration:** Integrated semantic search query dispatching (`SearchLibrarySemanticallyQuery`) and wired up navigation seamlessly through the updated `ReaderNavigationService`. * **Tests Hardening:** Added/adapted query assertions in `QueryTests.cs` to guarantee safe parameterization and error boundary mapping. #### 2. Qdrant Collection Provisioning & Vector Ingestion * **Dynamic Auto-Provisioning:** Implemented dynamic checking and lazy-creation of the `knowledge_units` collection using 768 dimensions and Cosine distance. * **High-Performance Ingestion:** Optimized `ProcessKnowledgeUnitsAsync` with high-performance batch embedding generation using `_embeddingGenerator` and deterministic MD5 GUIDs for stable, duplicate-free upsertion. * **Database Cache Clear Sync:** Integrated Qdrant collection deletion in `ClearCacheAsync` to ensure absolute consistency between the PostgreSQL database cache and vector database indices. #### 3. Cross-Platform MAUI Logging (Serilog Infrastructure) * **Serilog Integration:** Configured cross-platform Serilog routing in `SerilogConfiguration.cs`, streaming diagnostic logs safely across native platforms and the Blazor Webview container. * **Interop Bridge:** Built `BlazorLoggingBridge.cs` to capture web console messages and pipe them directly to the native host logger. * **Demo Interface:** Added an interactive `SerilogDemo.razor` sandbox under Pages. #### 4. Resolving 401 Load Errors (Authentication Handler Flow) * **Authentication Header Handler:** Implemented the `MobileAuthenticationHeaderHandler` to correctly extract, validate, and inject bearer JWT tokens into outbound API requests. * **Configuration-based API Host:** Structured standard API URI routing to use clean configuration bindings in `appsettings.json`. --- ### 🧪 Verification & Build Status * Run `dotnet build` from the solution root: Successfully compiled the full multi-targeted solution (`Liczba błędów: 0`). * All unit and integration tests successfully executed and verified (`dotnet test`). --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Co-authored-by: Marek Jaisński <jasins.marek@gmail.com> Reviewed-on: #51 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
📖 Nexus Reader
Nexus Reader is a state-of-the-art, cross-platform Blazor .NET 10 immersive e-book reader, powered by Native AOT, Clean Architecture, CQRS, and interactive D3.js Relationship Graphs built on vector-based AI semantics.
✨ Features & Architecture Highlights
📁 Ingestion & Description persistence
- Extracted and persistent book descriptions from EPUB package metadata during book ingestion.
- The
Descriptionfield propagates cleanly from theEbookentity through Mapster toLastReadBookDtoandUserProfileDto.
🔗 Deep-Link Routing
- Implemented deep-link route activation:
/reader/{bookId}?chapter=N. - Allows instant resume of reading session coordinates and loads the specific chapter chapter directly via URL query parameters.
🛡️ Downstream AI Resilience
- Standard resilience engine in
DependencyInjection.csutilizing the Polly package (ai-retry). - Automatically intercepts, handles, and retries on both rate-limits (
429 Too Many Requests) and downstream capacity overloads (503 ServiceUnavailable/high demand).
⚙️ Concurrent Request Deduplication
- Multi-client InteractiveAuto Blazor circuit synchronization is backed by a thread-safe active task registry in
KnowledgeServicewhich ensures that identical concurrent requests await a single shared task instance, eliminating redundant LLM queries.
🛠️ Build & Verification Gate
Ensure the dotnet workload matches the active SDK, and compile the full solution utilizing:
dotnet build NexusReader.slnx --no-restore
Run test suite:
dotnet test --no-restore
