For current architecture, see [CANONICAL_PLATFORM_ARCHITECTURE.md](../architecture/CANONICAL_PLATFORM_ARCHITECTURE.md).\n\n**Date:** June 27, 2026 \n**Status:** COMPLETE & DEPLOYED \n**Version:** v1.0 \n\n---\n\n## What Was Delivered\n\n### 1. Projection Manifest (435 lines)\n**File:** `apps/web/lib/projection-manifest.ts`\n\nDefines what each frontend can do.\n\nThree complete, production-ready projections:\n- **Customer Success** (45% platform, 8 capabilities)\n- **Executive Dashboard** (25% platform, 5 capabilities)\n- **Developer Console** (40% platform, 8 capabilities)\n\nEach projection includes:\n- Navigation structure\n- Widget definitions\n- Command definitions\n- Required capabilities\n- Permission requirements\n\n### 2. Gateway SDK (266 lines)\n**File:** `apps/web/lib/gateway-sdk.ts`\n\nThe ONLY way the frontend talks to the backend.\n\nType-safe client for:\n- Entity360 (entity context)\n- Memory (adaptive memory)\n- Twin (AI/chat capabilities)\n- Signals (risk detection)\n- Insights (AI recommendations)\n- Predictions (forecasts)\n- Handoff (multi-agent coordination)\n- Stream (real-time data)\n- MCP (200+ data sources)\n- Health (system monitoring)\n\nFeatures:\n- Full TypeScript support\n- Error handling\n- Session token management\n- Singleton pattern\n\n### 3. Design System (375 lines)\n**File:** `apps/web/lib/design-system.ts`\n\nCentralizes all design decisions.\n\nIncludes:\n- **Typography:** Sizes, weights, line heights\n- **Spacing:** Base scale, gaps, padding presets\n- **Colors:** Semantic design tokens\n- **Components:** Button, card, input, badge variants\n- **Interactions:** Transitions, animations, focus/hover states\n- **Hierarchy:** L1-L6 visual levels\n- **Layout:** Containers, grid, flexbox patterns\n- **Shadows:** Depth levels\n- **Breakpoints:** Responsive design\n\n### 4. Documentation (580 lines)\n**File:** `THREE_PILLARS_ARCHITECTURE.md`\n\nComplete guide with:\n- Architecture philosophy\n- Three pillar explanations\n- Code examples\n- Integration patterns\n- Adding new products\n- Benefits analysis\n- Migration guide\n\n### 5. Index File (69 lines)\n**File:** `apps/web/lib/index.ts`\n\nCentralized exports:\n```typescript\nexport { CUSTOMER_SUCCESS_PROJECTION, ... } from './projection-manifest'\nexport { getGateway, initializeGateway, ... } from './gateway-sdk'\nexport { designSystem, typography, ... } from './design-system'\n```\n\n---\n\n## Architecture Pattern\n\n```\nFrontend Component\n ↓\nImports three things:\n ├── Projection Manifest (What can I do?)\n ├── Gateway SDK (How do I talk to backend?)\n └── Design System (How do I look?)\n ↓\nComponent renders UI with structure, data, and styling\n```\n\n---\n\n## Key Principles\n\n1. **Projection Manifest** defines product experience\n - What navigation exists\n - What widgets are available\n - What commands are executable\n - What capabilities are required\n\n2. **Gateway SDK** provides backend access\n - Only way to call backend\n - Type-safe\n - Centralized error handling\n - Authentication aware\n\n3. **Design System** standardizes styling\n - Semantic color tokens\n - Centralized typography\n - Consistent spacing\n - Unified component patterns\n\n---\n\n## Usage Example\n\n```typescript\nimport {\n CUSTOMER_SUCCESS_PROJECTION,\n getGateway,\n designSystem,\n} from '@/lib'\n\n const projection = CUSTOMER_SUCCESS_PROJECTION\n const gateway = getGateway()\n\n // Render navigation from projection\n return (\n
\n \n\n \n {\n gateway.getEntity('customer-123').then(data => {\n setCustomer(data)\n })\n }, [])\n\n \n
