📒 Problem #5 · High Vector Similarity, Wrong Meaning

Classic RAG scores chunks by cosine similarity—close vectors ≠ correct logic.
Result: “looks relevant” chunks that derail answers. WFGY replaces surface matching with semantic residue checks.

🤔 Why Cosine Match Misleads

Weakness	Practical Failure
Embedding ≠ Understanding	Cosine overlap captures phrasing, not intent
Keywords ≠ Intent	Ambiguous terms bring unrelated chunks
No Semantic Guard	System never validates logical fit

⚠️ Example Mis‑Retrieval

User: “How do I cancel my subscription after the free trial?”
Retrieved chunk: “Subscriptions renew monthly or yearly, depending on plan.”
→ High cosine, zero help → hallucinated answer.

🛡️ WFGY Fix · BBMC Residue Minimization

B = I - G + m·c²      # minimize ‖B‖

Symbol	Meaning
I	Input semantic vector
G	Ground‑truth anchor (intent)
B	Semantic residue (error)

Large ‖B‖ → chunk is semantically off → WFGY rejects or asks for context.

🔍 Key Defenses

Layer	Action
BBMC	Computes residue; filters divergent chunks
ΔS Threshold	Rejects high semantic tension (ΔS > 0.6)
BBAM	Down‑weights misleading high‑attention tokens
Tree Anchor	Confirms chunk aligns with prior logic path

✍️ Quick Repro (1 min)

1️⃣  Start
> Start

2️⃣  Paste misleading chunk
> "Plans include yearly renewal."

3️⃣  Ask
> "How do I cancel a free trial?"

WFGY:
• ΔS high → chunk rejected  
• Prompts for trial‑specific info instead of hallucinating

🔬 Sample Output

Surface overlap detected, but content lacks trial‑cancellation detail.  
Add a policy chunk on trial termination or rephrase the query.
