+# Production-Safe Mode System - Implementation Complete
+
+## ✅ What Was Built
+
+### 1. **Realm vs Mode Separation**
+- **Realm** = Authority + Policy Boundary (enforced server-side)
+- **Mode** = Presentation + App Surface (user preference)
+
+### 2. **Single Source of Truth: App Registry**
+File: `shared/app-registry.ts`
+
+- **Canonical app dictionary** (`appsById`) - no duplication
+- **Mode manifests** - select app subsets per mode
+- **Capability system** - 9 capabilities (credential_verification, commerce, social, etc.)
+- **Policy metadata** per app:
+  - `requiresRealm`: "foundation" | "corporation" | "either"
+  - `requiresCapabilities`: array of required capabilities
+  - `navVisibleIn`: which modes show this app
+  - `routes`: all routes for route guarding
+
+### 3. **Database Schema**
+New tables in `migrations/0003_mode_system.sql`:
+
+```sql
+aethex_user_mode_preference
+  - user_id (unique)
+  - mode ("foundation" | "corporation")
+  - created_at, updated_at
+
+aethex_workspace_policy
+  - workspace_id (unique)
+  - enforced_realm (if set, users cannot switch)
+  - allowed_modes (json array)
+  - commerce_enabled, social_enabled, messaging_enabled
+  - created_at, updated_at
+```
+
+### 4. **Client-Side Protection**
+
+#### Route Guard (`client/src/hooks/use-route-guard.ts`)
+- Monitors location changes
+- Checks `canAccessRoute(path, realm, mode)`
+- Redirects with toast notification if access denied
+- Prevents manual URL navigation to restricted apps
+
+#### Mode Hook (`client/src/hooks/use-mode.ts`)
+- Fetches user mode preference from API
+- Fetches workspace policy
+- Respects `enforced_realm` (disables mode switching)
+- Updates mode preference via API
+
+### 5. **Server-Side Protection**
+
+#### Capability Guard Middleware (`server/capability-guard.ts`)
+- Maps endpoints to required capabilities
+- Checks `x-user-realm` header
+- Enforces realm requirements
+- Enforces capability requirements
+- Returns 403 with detailed error if access denied
+
+**Protected Endpoints:**
+```typescript
+/api/hub/messaging        → corporation, ["social", "messaging"]
+/api/hub/marketplace      → corporation, ["commerce", "marketplace"]
+/api/hub/projects         → corporation, ["social"]
+/api/hub/analytics        → corporation, ["analytics"]
+/api/hub/file-manager     → corporation, ["file_storage"]
+/api/os/entitlements/*    → ["credential_verification"]
+/api/os/link/*            → ["identity_linking"]
+```
+
+#### Mode API Endpoints (`server/routes.ts`)
+```
+GET  /api/user/mode-preference  → Get user mode
+PUT  /api/user/mode-preference  → Update user mode
+GET  /api/workspace/policy      → Get workspace policy
+```
+
+### 6. **App Distribution**
+
+#### Foundation Mode (7 apps)
+- Achievements (credential verification)
+- Passport (identity profile)
+- Curriculum (learning paths)
+- Events (programs and cohorts)
+- Lab (development environment)
+- Network (directory of verified builders)
+- OS Link (identity linking)
+
+#### Corporation Mode (15 apps)
+- All Foundation apps +
+- Messaging (direct messaging)
+- Marketplace (access to courses, tools, services)
+- Projects (portfolio showcase)
+- Code Gallery (code sharing)
+- Notifications (activity feed)
+- Analytics (engagement metrics)
+- File Manager (cloud storage)
+- Settings (preferences)
+
+### 7. **Key Design Decisions**
+
+#### ✅ Network App Clarified
+- **Foundation**: Directory of issuers/program cohorts + verified builders
+- **No DMs, no public feeds, no monetization hooks**
+- Remains in Foundation mode as a directory-only feature
+
+#### ✅ Marketplace Reworded
+- Changed from "Buy and sell credentials" (dangerous)
+- To "Access courses, tools, and services" (safe)
+- Credentials are **earned/issued**, not purchased
+- What's sold: course seats, audits, software licenses, service engagements
+
+#### ✅ OS Kernel Clearly Separated
+- Scope badge: "Kernel"
+- Accessible from both modes
+- Visually distinct (cyan accent)
+- Infrastructure layer, not a third mode
+

+
+## 🔒 Security Model
+
+### Multi-Layer Defense
+
+1. **Client Route Guard** → Prevents UI navigation
+2. **App Visibility Filter** → Hides unavailable apps
+3. **Server Capability Guard** → Blocks API calls
+4. **Workspace Policy** → Organizational enforcement
+
+### Enforcement Chain
+
+```
+User → Client checks mode → Server checks realm → Database checks capability → Action allowed/denied
+```
+
+---
+
+## 📊 Mode Comparison
+
+| Feature | Foundation | Corporation |
+|---------|-----------|-------------|
+| **Apps** | 7 core + OS | 7 core + 8 Hub + OS |
+| **Focus** | Credentials | Community + Commerce |
+| **Messaging** | ❌ | ✅ |
+| **Marketplace** | ❌ | ✅ |
+| **Projects** | ❌ | ✅ |
+| **File Storage** | ❌ | ✅ |
+| **Analytics** | ❌ | ✅ |
+| **Color** | Cyan/Blue | Purple/Pink |
+| **Label** | "AeThex Foundation" | "AeThex Hub" |
+
+---
+
+## 🚀 What's Enforced
+
+✅ **Route Access** - Manual URL navigation blocked  
+✅ **API Access** - Hub endpoints check realm + capabilities  
+✅ **App Visibility** - Only allowed apps shown in UI  
+✅ **Workspace Policy** - Organizations can lock users into Foundation  
+✅ **Capability Mapping** - Every Hub feature requires explicit capabilities  
+
+---
+
+## 🔄 Migration Status
+
+```bash
+✅ 0001_new_apps_expansion.sql  (10 Hub tables)
+✅ 0002_os_kernel.sql            (7 OS kernel tables)
+✅ 0003_mode_system.sql          (2 mode governance tables)
+
+Total: 19 tables deployed
+```
+
+---
+
+## 🧪 Testing
+
+Start dev server:
+```bash
+npm run dev
+```
+
+Visit `http://localhost:5000` and:
+1. Toggle between Foundation/Corporation modes
+2. Try accessing Hub apps in Foundation mode (should be blocked)
+3. Check browser console for access denied messages
+4. Try direct URL navigation to `/hub/messaging` in Foundation mode
+
+---
+
+## 📝 Result
+
+**Mode is now enforceable governance, not cosmetic theming.**
+
+Foundation becomes a credentialing/education console that feels institutional. Corporation becomes a full platform with commerce + community. OS Kernel remains shared infrastructure accessible to both.
+
+The distinction is now **enforceable at every layer**: UI visibility, client routing, server API access, and workspace policy.
