# Layer 6 — Connector & Integration Layer

> Connector registry, base connector telemetry, production connector partition, beta/demo connectors, and external ERP/CRM systems.

The registry-driven external connectivity surface of the [[pages/concepts/suitecentral-code-architecture|seven-layer code architecture]]. A canonical connector registry is the single source of truth for what ships and how it is wired: the production partition (NetSuite, Salesforce, Business Central, HubSpot, ShipStation — production-credential-tested, with Oracle at beta), plus demo-mode and stub connectors, all clearly labeled by source-level status declarations that CI audits against the code. Connectors in this layer are **purely executors, not decision-makers** — writes are gated upstream in [[pages/architecture/core-application-services|Layer 3]] and validated by [[pages/architecture/governance-safety|Layer 5]] before a connector ever executes them.

## Questions this layer answers

- Which connectors are production, beta, demo, or stub?
- What is the connector registry source of truth?
