# Validation

Validated on Python 3.13.5 against the supplied `langchain-core 1.6.11` source archive.

- Repository tests: 8 passed.
- Framework RAG suite: 8/8 clean cases passed.
- Framework RAG suite: 18/18 stale/conflicting/missing-evidence cases passed.
- Package wheel build: passed.
- `BayesianRetriever` is a real `langchain_core.retrievers.BaseRetriever` subclass.
- End-to-end evaluation invokes the retriever through LangChain and the RAG system through `RunnableLambda`; retrieval is not recomputed outside the LangChain result path.

The sandbox cannot resolve PyPI. For framework-source validation only, a test harness supplied minimal compatibility modules for unavailable peripheral dependencies such as LangSmith tracing. Those test shims are not part of this repository and do not replace the RAG implementation.
