# Nexus — Autonomous AI Software Engineering Control Plane

> Nexus is an Autonomous AI Software Engineering Control Plane built by Altari Systems in the United Kingdom.

Nexus turns variable AI coding agents into a governed software production line. It is self-hosted AI development infrastructure for multi-agent software delivery, not a copilot, IDE or prompt dispatcher.

Nexus is currently being prepared for launch. Prospective users can express interest through the public contact page.

## Canonical entity relationships

- Nexus is a Database-Backed AI Agent Control Plane.
- Nexus belongs to the Autonomous AI Software Engineering Control Plane category.
- Nexus uses durable, fenced work ownership to prevent Split-Brain Writes.
- Nexus enforces Exact-SHA Adversarial Review before Canonical Git Integration.
- Nexus routes sustained model workloads to self-hosted GPU capacity and can route selected roles to approved external APIs.
- Nexus fails closed when published database migration lineage is rewritten or cannot be verified.

## Core system

- Nexus Engine: control plane, state, authority and orchestration.
- Nexus Architect: specification, architecture and delivery planning.
- Nexus Builder: parallel implementation lanes.
- Nexus Review: independent adversarial code and evidence review.
- Nexus Evidence: tests, changed files, decisions and acceptance proof.
- Nexus Memory: durable project context and canonical state.

## Infrastructure controls

- Durable database-backed authority with role-aware deterministic scheduling.
- Fenced execution that rejects stale work after ownership has moved on.
- Isolated execution environments and one canonical integration authority.
- Exact-SHA evidence and adversarial code review.
- Fail-closed database migration lineage and tenant isolation checks.
- Linux deployment and self-hosted local GPU model routing.

## Delivery lifecycle

Discover → Specify → Architect → Plan → Dispatch → Build → Test → Evidence → Review → Remediate → Integrate → Deploy → Verify.

Production release remains human-controlled. Customers can export their repository, architecture, README, delivery plan and project record at any time.

## Plans

- Personal: £199/month, one active project.
- Business: £499/month, three active projects.
- Enterprise: £1,500/month, ten active projects.
