# Changelog
## [Unreleased]
### Changed
- **Download Models Progress**: `haiku-rag download-models` now shows real-time progress with Rich progress bars for Ollama model downloads
- **Refactored Download Models**: Moved core download logic to `HaikuRAG.download_models()` async generator that yields `DownloadProgress` events, separating business logic from UI
## [0.20.0] - 2025-11-28
### Added
- **Format Parameter for Text Conversion**: New `format` parameter for `convert()` and `create_document()` to specify content type
- Supports `"md"` (default) for markdown and `"html"` for HTML content
- HTML format preserves document structure (headings, lists, sections) in DoclingDocument
- Enables proper parsing of HTML content that was previously treated as plain text
- Document content is stored as markdown export for consistent display (original preserved in `docling_document_json`)
- Wix evaluation dataset now uses `html_content` with `format="html"` for better document structure
- **DoclingDocument Storage**: Full DoclingDocument JSON is now stored with each document, enabling rich context and visual grounding
- Documents store the complete DoclingDocument structure (JSON) and schema version
- Chunks store metadata with JSON pointer references (`doc_item_refs`), semantic labels, section headings, and page numbers

- **Enhanced Search Results**: `search()` and `expand_context()` now return full provenance information
- `SearchResult` includes `page_numbers`, `headings`, `labels`, and `doc_item_refs`
- QA and research agents use provenance for better citations (page numbers, section headings)
- **Type-Aware Context Expansion**: `expand_context()` now uses document structure for intelligent expansion
- Structural content (tables, code blocks, lists) expands to complete structures regardless of chunking
- Text content uses radius-based expansion via `text_context_radius` setting
- `max_context_items` and `max_context_chars` settings control expansion limits
- `SearchResult.format_for_agent()` method formats expanded results with metadata for LLM consumption
- **Visual Grounding**: View page images with highlighted bounding boxes for chunks
- Inspector modal with keyboard navigation between pages
- CLI command: `haiku-rag visualize <chunk_id>`
- Requires `textual-image` dependency and terminal with image support
- **Processing Primitives**: New methods for custom document processing pipelines
- `convert()` - Convert files, URLs, or text to DoclingDocument
- `chunk()` - Chunk a DoclingDocument into Chunk objects

- **Automatic Chunk Embedding**: `import_document()` and `update_document()` automatically embed chunks that don't have embeddings
- Pass chunks with or without embeddings - missing embeddings are generated
- Chunks with pre-computed embeddings are stored as-is
- **Visual Grounding**: View page images with highlighted bounding boxes for chunks
- Inspector modal with keyboard navigation between pages
- CLI command: `haiku-rag visualize <chunk_id>`
- Requires `textual-image` dependency and terminal with image support
- **Type-Aware Context Expansion**: `expand_context()` now uses document structure for intelligent expansion

- **Format Parameter for Text Conversion**: New `format` parameter for `convert()` and `create_document()` to specify content type
- Supports `"md"` (default) for markdown and `"html"` for HTML content
- HTML format preserves document structure (headings, lists, sections) in DoclingDocument
- Enables proper parsing of HTML content that was previously treated as plain text
- **Inspector Context Modal**: Press `c` in the inspector to view expanded context for the selected chunk
### Changed
- **Rebuild Performance**: Batched database writes during `rebuild` command reduce LanceDB versions by ~98%
- All rebuild modes (FULL, RECHUNK, EMBED_ONLY) now batch writes across documents
- Eliminates redundant per-document chunk deletions and vacuum calls
- Significantly reduces storage overhead and improves rebuild speed for large databases
- **BREAKING: Config Renamed**: `context_chunk_radius` renamed to `text_context_radius`
- **BREAKING: `create_document()` API**: Removed `chunks` parameter
- `create_document()` now always processes content (converts, chunks, embeds)
- Use `import_document()` for pre-processed documents with custom chunks
@ -68,14 +52,20 @@
- `content` and `docling_document_json` are mutually exclusive
- **BREAKING: Chunker Interface**: `DocumentChunker.chunk()` now returns `list[Chunk]` instead of `list[str]`
- Chunks include structured metadata (doc_item_refs, labels, headings, page_numbers)
- **Chunk Text Storage**: Chunks store raw text; headings prepended only at embedding time
- Stored chunk content stays clean without duplicate heading prefixes
- Local and serve chunkers now produce identical output
- **BREAKING: Config Renamed**: `context_chunk_radius` renamed to `text_context_radius`
- **Rebuild Performance**: Batched database writes during `rebuild` command reduce LanceDB versions by ~98%
- All rebuild modes (FULL, RECHUNK, EMBED_ONLY) now batch writes across documents
- Eliminates redundant per-document chunk deletions and vacuum calls
- Significantly reduces storage overhead and improves rebuild speed for large databases
- **Embedding Architecture**: Moved embedding generation from `ChunkRepository` to client layer
- Repository is now a pure persistence layer
- Client handles embedding via `_ensure_chunks_embedded()`
- **Chunk Text Storage**: Chunks store raw text; headings prepended only at embedding time
- Stored chunk content stays clean without duplicate heading prefixes
- Local and serve chunkers now produce identical output
- **Citation Models**: Introduced `RawSearchAnswer` for LLM output, `SearchAnswer` with resolved citations
- **Page Image Generation**: Always enabled for local docling converter (required for visual grounding)
- **Download Models Progress**: `haiku-rag download-models` now shows real-time progress with Rich progress bars for Ollama model downloads
