From 6765f9f497e170153f573e5a19931efa47938ad6 Mon Sep 17 00:00:00 2001 From: Mykola Pereyma Date: Thu, 11 Jun 2026 09:49:17 -0700 Subject: [PATCH 1/8] feat(core): add core module with types, providers, and ABCs Introduce graphrag_toolkit.core as the foundation layer replacing LlamaIndex internal types: - Node, Document, NodeRef, NodeWithScore, QueryBundle (Pydantic models) - LLMProvider ABC + BedrockLLMProvider (boto3 converse API) - EmbeddingProvider ABC + BedrockEmbeddingProvider (boto3 invoke_model) - PromptTemplate, ChatPromptTemplate - Retriever, Extractor, Transform, PostProcessor, QueryEngine ABCs - Pipeline runner, CallbackRegistry - Compatibility aliases (TextNode=Node, BaseNode=Node) All new code with comprehensive unit tests.

test fixtures to core types Replace LlamaIndex imports in top-level files and test suite: - config.py: LLMType/EmbeddingType use core providers - lexical_graph_index.py: custom SentenceSplitter as default chunker - lexical_graph_query_engine.py: core Response/QueryBundle types - LLMCache: wraps BedrockLLMProvider - Test fixtures: use core.types instead of llama_index.core.schema -
