# Connectivity

# Connectivity & Connector Architecture

## Purpose

Connect SpineWorkspace to systems where business data and actual operational state exist, feeding the Business Context Spine.

## The Tier-0 Principle

> **Business Context is the semantic foundation of SpineWorkspace.** Connectors feed the Business Context Spine, which IS the organization's memory. Without Business Context, connectors have nothing to serve.

## Connector classes

```text theme={null}
OAuth / Unified API
MCP
REST / GraphQL API
Webhook
Event
File / Document
Custom Provider
External Agent
```

## Architecture

```text theme={null}
Source System
 ↓
Connector
 ↓
Loader / Event Handler
 ↓
Normalizer
 ↓
Business Context Spine
```

For writes:

```text theme={null}
SpineWorkspace
 ↓
Capability
 ↓
Governance
 ↓
Execution Binding
 ↓
Connector
 ↓
Source System
```

## Provider authentication vs IntegrateWise authentication

* IntegrateWise auth establishes tenant/workspace/capability/governance access.
* Provider auth establishes consent to external-system data/actions.

## Connector invariant

Frontend must not directly import provider SDKs or call provider APIs.

Frontend calls stable platform contracts.
Platform resolves connector/provider implementation.
