Description
Summary
Introduces a lean
GraphSchemaExtractionOutputmodel for schema-from-text structured output (response_format) instead ofGraphSchema, then converts toGraphSchemaviaGraphSchema.from_extraction_outputso the rest of the pipeline is unchanged.Details

Smaller provider JSON schemas (no root
additional_*, fewer defs) and clearer separation between schema extraction LLM structure output format and runtime pipeline configGraphSchema.It will now be much easier to separate concerns between these two previous roles of
