# Guardian QS — MARSSIM Nuclear Decommissioning Platform
> Updated: April 2026 | https://kojie.works/llms.txt

## What Is Guardian QS?

Guardian QS is the only purpose-built MARSSIM Final Status Survey (FSS) management platform for nuclear decommissioning licensees. Built by CPWE AI, founded by James "Kojie" Collins.

Guardian QS manages the full NRC license termination workflow under 10 CFR 20.1402 and NUREG-1575 (MARSSIM, Rev. 1):

- **Survey Unit Management** — Class 1/2/3 classification, radionuclide assignment, DCGL_EW tracking, WRS/Sign Test pass/fail status
- **MARSSIM Statistical Testing** — Automated Wilcoxon Rank Sum (WRS) with mid-rank tie correction and SOF auto-aggregation; Sign Test fallback for Class 2/3; per NUREG-1575 §9.3.3
- **Kojie Tools Intelligence Panel** — Embedded in every survey unit: deep links to pre-filled calculators (N_min, Scan MDC, WRS, DCGL), nuclide-to-supply-chain vendor mapping (Cs-137 → Decon Chemical + RAM Transport; Co-60 → Waste Container; etc.), and remediation resources on FAIL
- **4-Agent AI Consensus** — NRC regulatory interpretation, margin analysis, and next-step recommendations from 4 independent AI agents with consensus scoring
- **Supply Chain Intelligence** — Vendor qualification across 10 supply chain categories: RAM transport, instrument suppliers, decon chemical, waste containers, engineering services, subcontractors, HVAC, electrical, construction
- **Crypto-Signed Audit Trail** — Every data change timestamped and hash-signed for NRC defensibility
- **NRC-Ready FSS Report Generation** — NUREG-1575 Appendix H format with all 11 RAI prevention checks
- **RWP / Work Permit Management** — Radiological Work Permit issuance, control levels, dose tracking
- **Photo Documentation** — Field photos with AI-powered deficiency detection and MARSSIM annotation
