+## Key Features
 
-* **Parallel Enrichment:** Utilizes a configurable multithreading to process multiple document chunks simultaneously across local LLM slots for high-speed ingestion.
-* **Deep Context Retrieval:** Unlike standard RAG, this system retrieves relevant chunks and then "peeks" at the full source file to provide the LLM with broader narrative context.
-* **Local-First:** Designed to run entirely on your hardware using **LM Studio**, keeping your campaign secrets private.

-## 🏗️ Architecture
-
-1. **Ingestion:** Scans `DATA_DIR` for `.md` files.
-2. **Chunking:** Splits documents into 800-character segments with overlap.
-3. **Enrichment:** A DSPy `IngestionAgent` analyzes each chunk to extract:
-    * **Synopsis:** A one-sentence summary.
-    * **Tags:** Plot points, item names, or themes.
-    * **Entities:** Specific NPCs, Locations, or Factions.
-4. **Vector Store:** Chunks and metadata are embedded using `text-embedding-qwen3` and stored in a local **Turso** database.
-5. **Interactive RAG:** A terminal loop that uses **ReAct (Reasoning and Acting)** to answer queries based on retrieved context.
