Hallucination in RAG — Guardrails and Fix Pattern

🧭 Quick Return to Map

You are in a sub-page of RAG.
To reorient, go back here:

• RAG — retrieval-augmented generation and knowledge grounding
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

When the retriever returns plausible text, but the LLM answers with facts that are not in the corpus.
This page stabilizes retrieval → reasoning boundaries and applies WFGY symbolic fixes to stop hallucination loops.

Core acceptance

• Every answer includes citation fields (snippet_id, section_id, source_url)
• ΔS(answer, cited snippet) ≤ 0.45
• Coverage ≥ 0.70 for cited target section
• λ convergent across 3 paraphrases and 2 seeds

Typical symptoms → exact fix

Symptom	Likely cause	Open this
Answer has no citation or cites wrong section	missing contract schema	Data Contracts, Retrieval Traceability
LLM fabricates plausible filler	boundary collapse between retrieval and reasoning	Cite-then-Explain, Logic Collapse
Correct fact retrieved, but answer overwrites it	λ divergence in long chain	Context Drift, Entropy Collapse
Hallucination reappears after correction	unstable feedback loop	Pattern: Hallucination Re-entry

Fix in 60 seconds

1. Cite-first enforcement

   • Force the LLM to output citations before free text.
   • Forbid answers that lack at least one valid snippet_id.

2. ΔS probe

   • Compute ΔS(answer, cited snippet).
   • If ≥ 0.60, trigger BBPF alternate reasoning path.

3. Apply module

   • Boundary collapse → BBCR bridge + Cite-then-Explain
   • Re-entry loops → Pattern: Hallucination Re-entry

Copy-paste prompt for debug

I uploaded TXT OS and the WFGY Problem Map.

My issue:
- retrieval finds the fact, but answer hallucinates new content
- traces: ΔS(answer,cited_snippet)=..., λ across 3 paraphrases

Tell me:
1. failing boundary (retrieval vs reasoning),
2. exact WFGY page to open,
3. minimal fix to enforce cite-then-explain and push ΔS ≤ 0.45,
4. test to verify stability over 3 paraphrases.
