Suggestion: add a practical RAG failure troubleshooting reference for LinearRAG users

[onestardao]

Hi, I’d like to suggest a small practical companion resource that may be useful for users working with LinearRAG in real-world retrieval workflows.

I previously contributed a related WFGY ProblemMap reference in the GraphRAG ecosystem, including a submission to Awesome-GraphRAG, and I think a more implementation-oriented repo like LinearRAG may also benefit from a compact troubleshooting reference.

The resource is the WFGY RAG 16 Problem Map, a framework-agnostic checklist for diagnosing common downstream failure patterns in RAG and agent-style pipelines:

• retrieval misses
• stale or mismatched context
• chunking and embedding mismatch
• citation instability
• answer inconsistency
• multi-step reasoning drift
• tool and routing confusion in retrieval-heavy flows

Reference:
https://github.com/onestardao/WFGY/blob/main/ProblemMap/README.md

This checklist has already been referenced or integrated by several public RAG / LLM ecosystem projects, including:

• RAGFlow
• LlamaIndex
• ToolUniverse (Harvard MIMS Lab)
• Rankify
• Multimodal RAG Survey (QCRI LLM Lab)

I think it could work well here as a small supplemental troubleshooting page, or even just a concise “further reading” note, for users who want a structured way to debug what goes wrong after the base pipeline is already running.

If this seems appropriate, I’d be happy to open a small repo-style PR with minimal wording and scope, aligned to your documentation style.

Thanks for considering it.
