[Feature Request] Document how HyperGraphRAG covers WFGY’s 16 RAG failure modes

[onestardao]

Hi HyperGraphRAG team,

thank you for open-sourcing this project.
The idea of using hypergraphs to structure retrieval and reasoning is one of the most interesting directions I’ve seen in RAG.

I’m the author of WFGY and the 16-mode RAG Failure ProblemMap:

• WFGY main repo: https://github.com/onestardao/WFGY
• 16-mode ProblemMap (RAG failure map): https://github.com/onestardao/WFGY/blob/main/ProblemMap/README.md

The ProblemMap has already been picked up by:

• Harvard MIMS Lab – ToolUniverse (as a robustness / RAG debugging entry)
• Univ. of Innsbruck – Rankify (RAG toolkit, using WFGY as a troubleshooting reference)
• QCRI LLM Lab – Multimodal RAG Survey (lists WFGY ProblemMap as a resource for RAG failure modes)

Why this might fit HyperGraphRAG

From your README and examples, HyperGraphRAG directly addresses some of the hardest RAG failure modes:

• No.1 hallucination & chunk drift – via structured neighborhood retrieval and graph constraints
• No.3 long reasoning chains – via explicit path traversal instead of opaque attention hops
• No.5 semantic ≠ embedding – by using graph structure to disambiguate similar embeddings
• No.8 debugging is a black box – graph structure makes the retrieval path inspectable

I think many users would benefit from understanding “which failure modes does HyperGraphRAG help with, and how?” in a more explicit way.

Proposal: tiny doc addition + optional appendix table

Would you consider a docs PR that adds:

1. A short section like:

RAG failure modes addressed by HyperGraphRAG
HyperGraphRAG can be seen as a structured fix for several common RAG failures (as catalogued by the WFGY 16-mode ProblemMap).
For example, it mitigates No.1 hallucination & chunk drift, No.3 long reasoning chains, No.5 semantic ≠ embedding, and No.8 debugging as a black box.
See: https://github.com/onestardao/WFGY/blob/main/ProblemMap/README.md

2. An optional appendix table (in the docs) with two columns:
   • ProblemMap mode (No.1–No.16)
   • whether / how HyperGraphRAG alleviates it (and which ones remain out-of-scope)

This would be completely documentation-only and would not change any code or experiments.

Why I think this helps your users

HyperGraphRAG is clearly more complex than vanilla “vector-store + reranker” RAG stacks.
Giving users a failure-mode lens can make it much easier to justify the extra complexity:

• “We adopt HyperGraphRAG because it directly targets ProblemMap modes 1,3,5,8.”

I can prepare the initial wording and table in a PR so you can adjust anything that feels off or overstated.

If this is not aligned with your plans, feel free to close – I mainly wanted to offer the ProblemMap as a structured vocabulary to explain the strengths and limits of HyperGraphRAG.
