OSCAL Digital Twin Playground

Purpose

OSCAL-powered digital twin playground with LangGraph agents. Compares OSCAL SSP (intended state) against live YAML config (actual state), detects drift, assesses risk, suggests mitigation, and generates OSCAL assessment-results and POA&M fragments automatically.

Architecture

LangGraph pipeline with 4 agents:

1. TwinSync — compares OSCAL SSP against live YAML state, identifies drift
2. Risk — assesses risk level of detected drift (critical/high/medium/low)
3. Mitigation — suggests remediation actions
4. Documentor — generates OSCAL assessment-results and POA&M fragments

Streamlit web UI with scenario runner for pre-built test cases.
