Node Catalog

This section indexes all control-graph nodes and SQL agent subgraph nodes. Each node has a dedicated reference page with inputs, outputs, contracts, and limitations.

For pipeline-level wiring, see ../pipeline.md. For subgraph wiring and lifecycle, see ../subgraphs/sql_agent.md.

Control graph nodes (main pipeline)

• CuratedMatcherNode (only when curated answers are configured)
• DatasourceResolverNode
• DecomposerNode
• EngineAggregatorNode
• AnswerSynthesizerNode

SQL agent subgraph nodes

• SchemaRetrieverNode
• ASTPlannerNode
• LogicalValidatorNode
• GeneratorNode
• ExecutorNode
• RefinerNode
