cybermaggedon cd5580be59 Extract-time provenance (#661) ... 1. Shared Provenance Module - URI generators, namespace constants, triple builders, vocabulary bootstrap 2. Librarian - Emits document metadata to graph on processing initiation (vocabulary bootstrap + PROV-O triples) 3. PDF Extractor - Saves pages as child documents, emits parent-child provenance edges, forwards page IDs 4. Chunker - Saves chunks as child documents, emits provenance edges, forwards chunk ID + content 5. Knowledge Extractors (both definitions and relationships): - Link entities to chunks via SUBJECT_OF (not top-level document) - Removed duplicate metadata emission (now handled by librarian) - Get chunk_doc_id and chunk_uri from incoming Chunk message 6. Embedding Provenance: - EntityContext schema has chunk_id field - EntityEmbeddings schema has chunk_id field - Definitions extractor sets chunk_id when creating EntityContext - Graph embeddings processor passes chunk_id through to EntityEmbeddings Provenance Flow: Document → Page (PDF) → Chunk → Extracted Facts/Embeddings ↓ ↓ ↓ ↓ librarian librarian librarian (chunk_id reference) + graph + graph + graph Each artifact is stored in librarian with parent-child linking, and PROV-O edges are emitted to the knowledge graph for full traceability from any extracted fact back to its source document.
