FAQ
- What is Pillar 8?
- Pillar 8 is ARIA's Verifiable-AI pillar: every generated response is grounded against an authoritative knowledge source and citations are emitted inline. Ungrounded output is blocked, not shipped.
- How does grounding work?
- The grounding engine retrieves candidate passages from the tenant knowledge base, scores each claim against them via a peer-review model, and attaches citation markers. Claims without supporting evidence trigger an ethics-gate refusal.
- Can I export the grounding evidence?
- Yes. Every response produces a downloadable attribution PDF containing the exact source passages, confidence per claim, and the peer-review verdict.
- Is Pillar 8 exposed over MCP?
- Yes. MCP tool #20 'verify_claim' and tool #21 'attribution_report' let external agents verify ARIA output programmatically.
