Remove redundant metadata (#685) The metadata field (list of triples) in the pipeline Metadata class was redundant. Document metadata triples already flow directly from librarian to triple-store via emit_document_provenance() - they don't need to pass through the extraction pipeline. Additionally, chunker and PDF decoder were overwriting metadata to [] anyway, so any metadata passed through the pipeline was being discarded. Changes: - Remove metadata field from Metadata dataclass (schema/core/metadata.py) - Update all Metadata instantiations to remove metadata=[] parameter - Remove metadata handling from translators (document_loading, knowledge) - Remove metadata consumption from extractors (ontology, agent) - Update gateway serializers and import handlers - Update all unit, integration, and contract tests 2026-03-11 10:51:39 +00:00			`from dataclasses import dataclass`
