# Changelog

All notable changes to Library Desk will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [1.3.2] - 2025-12-22

### Changed

- **Consolidated Ollama model configuration** - All LLM operations now use single `OLLAMA_MODEL` environment variable
  - Removed separate `reranker_model` setting
  - HybridRAG re-ranking, consolidation analysis, and wiki page writing all use the same model
  - Improves VRAM efficiency by keeping one model hot
- Added `OLLAMA_EMBEDDING_MODEL` environment variable for embedding model (previously overloaded `OLLAMA_MODEL`)
- Updated WikiPageWriter to accept settings instead of hardcoded model name

## [1.3.1] - 2025-12-16

### Fixed

- Smart create endpoint missing `content_extractor` dependency causing 500 errors on `POST /wiki/pages/smart-create`

## [1.3.0] - 2025-12-15

### Changed

- **Two-Stage RRF Architecture** - Major refactor to level the playing field between wiki and web results
  - Stage 1: Vector and graph results merged into single "wiki" ranking using mini-RRF
  - Stage 2: Final RRF between wiki (single source) and web (single source)
  - Wiki pages no longer get 2x advantage from appearing in both vector and graph searches
  - Multi-source confirmation still determines wiki internal ranking

- **Skip synonyms in graph search** - LLM-generated synonyms (e.g., "author") no longer match unrelated graph entities (e.g., "author2000")
  - Vector search still uses synonyms for semantic similarity
  - Graph search uses only core keywords for exact entity matching

### Added

- `VECTOR_SIMILARITY_THRESHOLD` config setting (default: 0.7) to filter weak vector matches
- Deduplication in graph search to prevent same document appearing multiple times

### Fixed

- Graph search duplicate entity bug where same document could appear twice if entity linked multiple times

## [1.2.1] - 2025-12-15

### Fixed

- HybridRAG router missing `content_extractor` dependency causing 500 errors on `/query/hybrid` endpoint

## [1.2.0] - 2025-12-15

### Added

- **RAG Search Endpoint** (`POST /rag/search`)
  - Web, news, and image search via SearXNG
  - Full content extraction using Trafilatura (F1 score 0.958)
  - Redis caching with configurable TTL
  - Markdown sources summary for LLM consumption
  - Returns both extracted content and original snippets

- **Content Extraction Endpoints** (`/content/*`)
  - `POST /content/extract` - Extract content from a single URL
  - `POST /content/extract/batch` - Batch extraction (up to 20 URLs)
  - Reusable ContentExtractor client for use across the codebase

- **HybridRAG Content Extraction Enhancement**
  - Web search results now include full extracted content via Trafilatura
  - Falls back to original snippets if extraction fails
  - Improves context quality for LLM re-ranking and consumption

### Changed

- Added new configuration options:
  - `SEARCH_CACHE_TTL` - Search cache TTL in seconds (default: 300)
  - `SEARCH_TIMEOUT` - SearXNG timeout (default: 10s)
  - `CONTENT_EXTRACTION_TIMEOUT` - Per-URL extraction timeout (default: 5s)
  - `CONTENT_MAX_LENGTH` - Max extracted content length (default: 2000)
  - `SEARCH_DEFAULT_LIMIT` - Default search results (default: 10)

### Dependencies

## [1.1.0] - 2025-12-11

### Added

- **Smart Page Creation Endpoint** (`POST /wiki/pages/smart-create`)
  - Combines HybridRAG research with LLM content generation
  - Searches existing wiki, knowledge graph, and web for topic context
  - Uses WikiPageWriter to synthesize findings into structured wiki content
  - Auto-generates page path from topic if not provided
  - Returns research summary with source counts

- **Bidirectional Entity Linking**
  - New shared utility (`entity_linking_utils.py`) for reusable entity linking
  - Forward links: Links entities mentioned in new pages to existing entity pages
  - Backward links: Updates existing pages that mention the new entity
  - Runs automatically in background after smart page creation

- **Version Management**
  - Added `pyproject.toml` with project metadata and version
  - Version is now read from `pyproject.toml` (single source of truth)
  - Health check endpoint returns current version
  - FastAPI docs show current version

### Changed

- Updated `config.py` to read version from `pyproject.toml`
- Updated `main.py` to use centralized version
