# Gantlett Systems Inc. (GSI)

> Models generate code; control systems make it production-grade. Deterministic Agent Control Systems, Anti-Reward-Hacking AST Rails, and Air-Gapped Sovereign GPU Infrastructure.

Gantlett Systems Inc. (GSI, https://gantlett.io) is the commercial systems architecture and sovereign AI infrastructure practice founded and led directly by Principal Systems Architect Mark Gantlett (25 years enterprise systems engineering [2001-2026], Federal & Ontario Corporation, Canada).

## Category Definition (Deterministic Agent Control Systems)

Every AI vendor builds a faster code-generation engine while leaving production `main` branches unguarded. GSI installs a dedicated **Transactional Agent Control Layer (`Nomos`)** beneath enterprise engineering teams (5 to 100+ developers) - distinct from AI coding agents, human style linters, and advisory prompt files - cutting cloud retry spend by 80%+ and deploying air-gapped local SLM execution.

## Core Institutional Engagements (https://gantlett.io/#pillars)

1. **14-Day AI Governance & Seam Charter Pilot (https://gantlett.io/seam-pilot):** Fixed-scope discretionary pilot ($15,000 - $25,000 USD) isolating one high-friction module seam in read-only `main`, Golden Master characterization tests, custom compiled AST & domain unit-lock sensor probes, and cryptographic Git Notes audit receipts.
2. **Air-Gapped Sovereign AI & Turnkey Hardware Appliances:** Private VPC, on-premise bare metal, or pre-configured NixOS + Nomos Sovereign local GPU appliances delivering 70%+ $0 local SLM resolution with zero external code exfiltration.
3. **Nomos Sovereign Platform & Multi-Agent Execution:** Commercial licensing and deployment of the Sovereign Tier 2 coding engine (`nomos code`), orthogonal adversarial critics, and Nomos Cockpit DAG control plane.
