Antigravity	23acaeb705	feat: KM-RAG Polyglot Ingestion Pipeline Migration (#46) ... Resolves the KM-RAG Polyglot Persistence and Background Ingestion Pipeline Migration task. ### Key Changes 1. **Infrastructure Migration**: Integrated Qdrant (for vector embeddings) and Neo4j (for concept graphs), reducing reliance on PostgreSQL pgvector storage. 2. **Concurrent Background Job**: Implemented a robust Hangfire `EbookIngestionJob` utilizing Polly exponential retries for transient 429 rate limits, executing three core ingestion tasks concurrently via `Task.WhenAll`. 3. **Data Layer**: Standardized database schemas and entities; retained `Pgvector.EntityFrameworkCore` for migration compilation compatibility. 4. **Wasm Client & Tests**: Implemented client support for semantic search and refactored related tests in `QueryTests.cs` to mock `IKnowledgeService`. ### Verification Status - **Build**: Successfully compiles with `dotnet build NexusReader.slnx --no-restore` (0 errors). - **Tests**: All 5 unit tests pass cleanly with `dotnet test NexusReader.slnx --no-restore`. **Resolve** #47 --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #46 Reviewed-by: Marek Jaisński <jasins.marek@gmail.com> Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>	2026-05-20 18:15:28 +00:00
Antigravity	541e9e1fb5	feat(ai-ux): deduplicate AI queries, handle ServiceUnavailable retries, and optimize reader canvas graph prerendering (#44) ... This Pull Request encapsulates all outstanding AI, Blazor InteractiveAuto lifecycle, pgvector, and Firefox authorization/session compatibility fixes. ### Key Accomplishments: 1. **Concurrent Request Deduplication (Option B):** Implemented a thread-safe active task registry in `KnowledgeService` that groups concurrent graph extraction queries for the same content, preventing duplicate AI calls completely. 2. **Resilience Strategy for Downstream Demands:** Extended the `ai-retry` resilience pipeline to automatically intercept and retry on temporary Google API `503 ServiceUnavailable` / `high demand` spikes. 3. **Interactive Graph Generation Guard (Option A):** Prevented server-side prerender-phase graph requests in the reader canvas component. 4. **Firefox Compatibility & Cookie Handler:** Implemented an authentication endpoint and hybrid hidden-form submission flow to solve login, registration, and logout redirections and cookies securely. 5. **Autoscrolling & Graph Exclusions:** Added concept-to-block smooth scrolling, active block badging, and filtered out markdown code blocks from being extracted as nodes. All unit tests compiled and passed 100% cleanly. --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #44 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>	2026-05-18 17:53:36 +00:00
