For current architecture, see [CANONICAL_PLATFORM_ARCHITECTURE.md](../architecture/CANONICAL_PLATFORM_ARCHITECTURE.md).\n\n## Overview\n\n**Continuity Bridge** is the unified ecosystem platform built on the **One Single Connector** architecture. It seamlessly integrates authentication, authorization, multi-provider support, and the Spine central nervous system into a cohesive platform.\n\n## What Was Built\n\n### 1. Complete Provider-Agnostic Architecture\n\n**Four Provider Layers:**\n1. **Authentication**: Supabase Auth ✓ | Clerk ✓\n2. **Database**: Supabase PostgreSQL ✓ | Cloudflare D1 ✓\n3. **AI Models**: Claude ✓ | GPT ✓ | Groq ✓\n4. **Agent Orchestration**: Vercel AI ✓ | LangChain ✓\n\n**Result:** 24 supported combinations, zero vendor lock-in, zero code changes to switch providers.\n\n### 2. One Single Connector (Central Nervous System)\n\n**Architecture:**\n```\nApplications\n    ↓\nuseConnector() hooks\n    ↓\ngetConnector() singleton\n    ↓\nconnector.getService('auth|db|ai|agent')\n    ↓\nService Factories (provider instances)\n    ↓\nSpine API (health, lifecycle, signals)\n    ↓\nMCP Pool (20+ external service bridges)\n```\n\n**Capabilities:**\n- Single entry point for entire ecosystem\n- Unified lifecycle management\n- Real-time health monitoring\n- Heartbeat to Spine (30-second intervals)\n- Bridged connection to 20+ external services\n\n### 3. Auth ↔ Connector Integration (Continuity Bridge Flow)\n\n**User Journey:**\n```\n1. IDENTITY\n   User logs in → Clerk or Supabase authenticates\n\n2. AUTHORIZATION  \n   System checks role → Loads permissions → Creates auth context\n\n3. APPROVAL\n   Modal appears → User reviews → Approves connection\n\n4. CONNECTION\n   One Connector initializes → Connects to Spine → Bridges activated\n\n5. OPERATION\n   Full ecosystem available → All services through One Connector\n```\n\n**Components:**\n- `ConnectorApprovalService` - Orchestrates flow\n- `ConnectorApprovalModal` - Beautiful UI\n- `useConnectorApproval` hook - React integration\n- `AuthConnectorProvider` - Automatic flow wrapper\n\n### 4. MCP Pool Configuration\n\n**Connected Services:**\n- **IntegrateWise Platform**: Knowledge, Memory, Spine, Signals, Proposals, Books\n- **Development**: GitHub, Figma, Notion, Playwright, VS Code\n- **Infrastructure**: Cloudflare (Workers, D1, KV), AWS (DynamoDB, Lambda), Firebase\n- **Services**: Supabase, Stripe, Slack\n- **Knowledge**: AWS KB, Cloudflare Docs, Context7, HuggingFace\n\n## Complete File Structure\n\n```\napps/web/lib/\n├── connector/                          (One Connector -
