mjasin 93133a49b6 feat(intelligence): implement global hybrid search engine and monetization logic
- Created IUserLibraryStore and IVectorSearchStore abstractions to decouple relational DB and Qdrant gRPC logic from Application Layer
- Implemented MediatR GetGlobalIntelligenceQuery with value-first teaser RAG monetization logic
- Registered new request and response DTOs in AppJsonContext for Native AOT source-generated serialization
- Bound RagMonetizationOptions via IOptions pattern in appsettings.json configuration
- Added POST /api/intelligence endpoint on server and implemented GetGlobalIntelligenceAsync in WASM client service
- Refactored Intelligence.razor to consume the backend-driven global hybrid search Q&A engine

📖 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 Description field propagates cleanly from the Ebook entity through Mapster to LastReadBookDto and UserProfileDto.
  • 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.cs utilizing 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 KnowledgeService which 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

🗄️ Database Migrations

Automatic database migrations at startup (MigrateAsync()) have been disabled to ensure compatibility with Native AOT compilation and prevent locking issues in multi-instance environments.

To apply database migrations locally, run the EF Core migration command from the solution root:

dotnet ef database update --project src/NexusReader.Infrastructure --startup-project src/NexusReader.Web
