Question 1

What is the difference between Constitutional AI and RAG?

Accepted Answer

RAG (Retrieval-Augmented Generation) grounds AI responses in retrieved documents but cannot deterministically prevent unsafe outputs. Constitutional AI constrains what the system can output through mathematical rules โ€” in the RCT Ecosystem, the FDIA equation's Architect gate (A=0โ’F=0) ensures output is blocked unconditionally when required. RAG is about knowledge quality; Constitutional AI is about behavioral guarantees.

Question 2

Can you use RAG and Constitutional AI together?

Accepted Answer

Yes. The RCT Ecosystem combines both approaches. RAG provides factual grounding through RCTDB retrieval, while Constitutional AI (FDIA framework) provides deterministic safety constraints. Together, they achieve a 0.3% hallucination rate โ€” compared to ~3โ€“5% for RAG alone and ~12โ€“15% for unguarded LLMs.

Question 3

Does RAG prevent hallucinations?

Accepted Answer

RAG reduces hallucination by grounding responses in retrieved documents, but it does not deterministically prevent them. A model can still ignore retrieved context or confabulate. RAG-only systems typically achieve 3โ€“5% hallucination rates. Constitutional AI adds mathematical safety constraints on top of retrieval to reduce this further.

Question 4

What is a constitutional AI kill switch?

Accepted Answer

In the RCT Ecosystem, the FDIA Architect variable (A) acts as a constitutional kill switch. When A=0, the system mathematically guarantees F=0 โ€” no output is produced regardless of what any LLM would generate. This is implemented as a hard gate in core/kernel/fdia.py, not a soft preference.

Question 5

How does Constitutional AI provide a PDPA audit trail?

Accepted Answer

Every RCT Ecosystem query writes its full provenance chain to RCTDB โ€” an 8-dimensional memory schema that records the query hash, FDIA scores (D, I, A, F), model chain, consensus result, and provenance trail. This automatically generates the audit evidence required for PDPA Section 33 (right to explanation) and Section 34 (right to object).
