Peer-First Conversational AI
Crisis-Prevention Co-Pilot

The LLM doesn't try to be the help. It routes the right signal to the right person at the right time.

Reference architecture proven on company-owned production infrastructure today. Portable to Azure Government Cloud upon Phase I award.

8-Layer Reference Architecture

Every component has a direct peer in Azure. The Phase I lift is a deploy-config change — not a re-architecture. Crisis flag → peer-first → VCL fallback is a single deterministic state machine, independent of LLM model selection.

Responsible

Mandatory human-in-the-loop. No LLM output bypasses the escalation rule.

Traceable

Every classification ships with framework citation (C-SSRS, Joiner ITS) and reasoning.

Governable

Escalation rule is data, not a code path inferred from model output.

Section 03 · Check-in

How are you, really?

No login. No identity binding. Text is hashed before anything is written down.
