# Validation

Validated on Python 3.13.5 against the supplied `langgraph 1.2.16` and `langchain-core 1.6.11` source archives.

- 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.
- The orchestration is a real compiled `langgraph.graph.StateGraph`.
- Validated graph nodes: `START`, `retrieve`, `assess`, `generate`, `abstain`, `END`.

The sandbox cannot resolve PyPI. For framework-source validation only, a test harness supplied minimal compatibility modules for unavailable peripheral tracing/checkpoint/SDK dependencies. Those test shims are not part of this repository; the graph builder/executor under test is the supplied LangGraph source.
