+# DAK Framework Integration Summary
+
+## Overview
+
+This document summarizes the integration of the WHO SMART Guidelines DAK Logical Model framework (from PR #1111) into the User Scenarios functionality.
+
+## Integration Completed
+
+### Date: October 16, 2025
+
+### Components Integrated
+
+1. **UserScenariosManager.js** - Fully integrated with DAK framework
+2. **dakIntegrationService.js** - New bridge service created
+3. **dakFrameworkService.js** - Updated to use DAK framework for persona loading
+
+## Key Changes
+
+### 1. New Service: `dakIntegrationService.js`
+
+**Purpose**: Bridges React components with @sgex/dak-core Component Objects
+
+**Key Methods**:
+- `initialize(owner, repo, branch)` - Creates DAKObject for repository
+- `loadUserScenarios()` - Loads scenarios via UserScenarioComponent
+- `loadPersonas()` - Loads personas via GenericPersonaComponent
+- `saveUserScenario(data)` - Saves scenario with automatic dak.json update
+- `validateUserScenario(data)` - Validates scenario data
+
+**Benefits**:
+- Clean separation between React and DAK framework
+- Automatic dak.json management
+- Source resolution (canonical, URL, inline)
+- Built-in validation
+
+### 2. Updated: `dakFrameworkService.js`
+
+**Changes**:
+- Now uses `dakIntegrationService` for persona loading
+- Maintains backwards compatible fallback (`getActorsLegacy`)
+- Automatic cache invalidation on data changes
+
+**Migration Path**:
+```javascript
+// Old way
+const actors = await loadActorsFromGitHub(owner, repo, branch);
+
+// New way
+const actors = await dakFrameworkService.getActors(owner, repo, branch);
+// Internally uses dakIntegrationService → GenericPersonaComponent
+```
+
+### 3. Refactored: `UserScenariosManager.js`
+
+**Old Approach**:
+- Direct file manipulation with githubService
+- Manual dak.json updates
+- Custom parsing logic
+
+**New Approach**:
+- Uses `dakIntegrationService.loadUserScenarios()`
+- Uses `dakIntegrationService.saveUserScenario()`
+- Automatic dak.json management
+- Built-in validation and source resolution
+
+**Code Example**:
+```javascript
+// Initialize DAK framework
+await dakIntegrationService.initialize(owner, repo, branch);
+
+// Load scenarios
+const scenarios = await dakIntegrationService.loadUserScenarios();
+
+// Save scenario
+await dakIntegrationService.saveUserScenario({
+  id: 'Anc-registration-001',
+  title: 'ANC Registration Scenario',
+  markdown: content,
+  actors: ['Healthcare-worker', 'Pregnant-woman'],
+  description: 'User scenario for ANC registration'
+});
+// Automatically saves markdown file + updates dak.json
+```

+
+### Save Flow
+
+1. **User clicks Save** in UserScenariosManager
+2. **Component calls** `dakIntegrationService.saveUserScenario(data)`
+3. **Integration service**:
+   - Gets UserScenarioComponent from DAKObject
+   - Calls `component.save(data, options)`
+4. **UserScenarioComponent**:
+   - Serializes data to markdown format
+   - Calls `stagingGroundIntegration.saveComponentArtifact()`
+   - Creates/updates source in dak.json
+   - Calls `stagingGroundIntegration.saveDakJson()`
+5. **StagingGroundIntegrationService**:
+   - Saves markdown file to staging ground
+   - Updates dak.json with source reference
+   - Saves dak.json to staging ground
+6. **Result**: Both files staged for commit
+
+### Load Flow
+
+1. **Component mounts** and calls `dakIntegrationService.loadUserScenarios()`
+2. **Integration service**:
+   - Gets UserScenarioComponent from DAKObject
+   - Calls `component.getSources()` to get dak.json sources
+   - Resolves each source via `component.resolveSource(source)`
+3. **UserScenarioComponent**:
+   - For each source, determines location (staging ground or repository)
+   - Loads content via `stagingGroundIntegration.loadComponentArtifact()`
+   - Parses content to data structure
+   - Returns resolved data
+4. **Integration service**: Returns array of scenario objects to component
+
+## Benefits of Integration
+
+### 1. Standards Compliance
+- ✅ Uses official WHO SMART Guidelines DAK logical model
+- ✅ Follows established patterns from PR #1111
+- ✅ Compatible with other DAK Component editors
+
+### 2. Automatic dak.json Management
+- ✅ No manual JSON manipulation needed
+- ✅ Automatic source creation/update on save
+- ✅ Consistent dak.json structure across all components
+
+### 3. Source Resolution
+- ✅ Supports canonical URIs
+- ✅ Supports absolute and relative URLs
+- ✅ Supports inline instance data
+- ✅ Automatic resolution prioritizes staging ground
+
+### 4. Validation
+- ✅ Built-in validation through Component Objects
+- ✅ Consistent validation rules
+- ✅ Extensible validation framework
+
+### 5. Staging Ground Integration
+- ✅ Seamless integration via StagingGroundIntegrationService
+- ✅ All changes staged before commit
+- ✅ Draft changes visible immediately
+
+### 6. Backwards Compatibility
+- ✅ Legacy fallback methods maintained
+- ✅ Gradual migration path for other components
+- ✅ Existing code continues to work
+
+## Migration Guide for Other Components
+
+### Step 1: Initialize DAK Integration
+
+```javascript
+import dakIntegrationService from '../services/dakIntegrationService';
+
+useEffect(() => {
+  const init = async () => {
+    await dakIntegrationService.initialize(owner, repo, branch);
+  };
+  init();
+}, [owner, repo, branch]);
+```
+
+### Step 2: Replace Direct File Access
+
+**Before**:
+```javascript
+const response = await githubService.octokit.rest.repos.getContent({
+  owner, repo, path: 'input/file.md', ref: branch
+});
+const content = atob(response.data.content);
+```
+
+**After**:
+```javascript
+const component = dakIntegrationService.getDAKObject().userScenarios;
+const scenarios = await component.retrieveAll();
+```
+
+### Step 3: Replace Manual dak.json Updates
+
+**Before**:
+```javascript
+// Load dak.json
+const dakResponse = await githubService.octokit.rest.repos.getContent(...);
+let dakData = JSON.parse(atob(dakResponse.data.content));
+
+// Update manually
+dakData.userScenarios.push(newScenario);
+
+// Save manually
+stagingGroundService.updateFile('dak.json', JSON.stringify(dakData));
+```
+
+**After**:
+```javascript
+// Just save - dak.json is automatically updated
+await dakIntegrationService.saveUserScenario(scenarioData);
+```
+
+## Testing Recommendations
+
+### 1. Unit Tests
+- Test dakIntegrationService methods
+- Test source resolution
+- Test validation logic
+
+### 2. Integration Tests
+- Test complete save flow
+- Test load flow with staging ground data
+- Test dak.json auto-update
+
+### 3. E2E Tests
+- Test creating new scenario
+- Test editing existing scenario
+- Test persona variable substitution
+- Verify dak.json structure
+
+### 4. Manual Testing Checklist
+- [ ] Create new user scenario
+- [ ] Edit existing user scenario
+- [ ] Use persona variable dropdown
+- [ ] Toggle edit/preview modes
+- [ ] Save changes to staging ground
+- [ ] Verify dak.json is updated correctly
+- [ ] Check staging ground shows both markdown and dak.json
+- [ ] Reload page and verify scenario loads correctly
+- [ ] Test with staged changes in staging ground
+- [ ] Test ID validation
+
+## Future Enhancements
+
+### Planned
+1. Update PersonaViewer to use DAK framework
+2. Add validation UI indicators
+3. Implement source resolution UI (show canonical/URL/inline)
+4. Add scenario templates
+5. Enhanced persona variable autocomplete
+
+### Considerations
+1. Consider extracting bridge pattern to reusable hook (`useDakComponent`)
+2. Consider adding React Context for DAKObject (ComponentObjectProvider)
+3. Consider adding optimistic UI updates
+4. Consider adding undo/redo support
