+
+**All code comments must be in English**, regardless of the user's language. This ensures:
+
+- Consistent codebase for international collaboration
+- Better compatibility with AI tools
+- Easier code review and maintenance
+
+```typescript
+// ✅ GOOD: English comments
+function calculateTotal(items: Item[]): number {
+  // Sum up all item prices
+  return items.reduce((sum, item) => sum + item.price, 0);
+}
+
+// ❌ BAD: Non-English comments
+function calculateTotal(items: Item[]): number {
+  // Additionner tous les prix des articles
+  return items.reduce((sum, item) => sum + item.price, 0);
+}
+```
+
+This rule applies to:
+
+- Inline comments
+- Function/class documentation (JSDoc)
+- Block comments explaining logic
+- TODO/FIXME notes
+- Commit messages (covered in Git Workflow section)
+
+**Exception**: User-facing strings in UI components may be in any language (they will be localized later).

+# TASK-009: Template System Refactoring
+
+**Status**: 📋 Planned  
+**Priority**: Medium  
+**Complexity**: Medium  
+**Estimated Effort**: 2-3 days
+
+## Context
+
+The current project template system has several issues:
+
+- Path resolution fails in webpack bundles (`__dirname` doesn't work correctly)
+- No proper template provider for local/bundled templates
+- Template loading depends on external URLs or fragile file paths
+- New projects currently use a programmatic workaround (minimal project.json generation)
+
+## Current Temporary Solution
+
+As of January 2026, new projects are created programmatically in `LocalProjectsModel.ts`:
+
+```typescript
+// Create a minimal Hello World project programmatically
+const minimalProject = {
+  name: name,
+  components: [
+    /* basic App component with Text node */
+  ],
+  settings: {},
+  metadata: {
+    /* ... */
+  }
+};
+```
+
+This works but is not ideal for:
+
+- Creating rich starter templates
+- Allowing custom/community templates
+- Supporting multiple bundled templates (e.g., "Hello World", "Dashboard", "E-commerce")
+
+## Goals
+
+### Primary Goals
+
+1. **Robust Template Loading**: Support templates in both development and production
+2. **Local Templates**: Bundle templates with the editor that work reliably
+3. **Template Gallery**: Support multiple built-in templates
+4. **Custom Templates**: Allow users to create and share templates
+
+### Secondary Goals
+
+1. Template versioning and migration
+2. Template metadata (screenshots, descriptions, categories)
+3. Template validation before project creation
+4. Template marketplace integration (future)
+
+## Proposed Architecture
+
+### 1. Template Storage Options
+
+**Option A: Embedded Templates (Recommended)**
+
+- Store templates as JSON structures in TypeScript files
+- Import and use directly (no file I/O)
+- Bundle with webpack automatically
+- Example:
+
+```typescript
+export const helloWorldTemplate: ProjectTemplate = {
+  name: 'Hello World',
+  components: [
+    /* ... */
+  ],
+  settings: {
+    /* ... */
+  }
+};
+```
+
+**Option B: Asset-Based Templates**
+
+- Store templates in `packages/noodl-editor/assets/templates/`
+- Copy to build output during webpack build
+- Use proper asset loading (webpack copy plugin)
+- Access via runtime asset path resolution
+
+**Option C: Hybrid Approach**
+
+- Small templates: embedded in code
+- Large templates: assets with proper bundling
+- Choose based on template size/complexity
+
+### 2. Template Provider Architecture
+
+```typescript
+interface ProjectTemplate {
+  id: string;
+  name: string;
+  description: string;
+  category: string;
+  version: string;
+  thumbnail?: string;
+
+  // Template content
+  components: ComponentDefinition[];
+  settings: ProjectSettings;
+  metadata?: Record<string, unknown>;
+}
+
+interface TemplateProvider {
+  name: string;
+  list(): Promise<ProjectTemplate[]>;
+  get(id: string): Promise<ProjectTemplate>;
+  canHandle(id: string): boolean;
+}
+
+class EmbeddedTemplateProvider implements TemplateProvider {
+  // Returns templates bundled with the editor
+}
+
+class RemoteTemplateProvider implements TemplateProvider {
+  // Fetches templates from Noodl docs/CDN
+}
+
+class LocalFileTemplateProvider implements TemplateProvider {
+  // Loads templates from user's filesystem (for custom templates)
+}
+```
+
+### 3. Template Manager
+
+```typescript
+class TemplateManager {
+  private providers: TemplateProvider[];
+
+  async listTemplates(filter?: TemplateFilter): Promise<ProjectTemplate[]> {
+    // Aggregates from all providers
+  }
+
+  async getTemplate(id: string): Promise<ProjectTemplate> {
+    // Finds the right provider and fetches template
+  }
+
+  async createProjectFromTemplate(template: ProjectTemplate, projectPath: string, projectName: string): Promise<void> {
+    // Creates project structure from template
+  }
+}
+```
+
+## Implementation Plan
+
+### Phase 1: Foundation (1 day)
+
+- [ ] Define `ProjectTemplate` interface
+- [ ] Create `TemplateProvider` interface
+- [ ] Implement `EmbeddedTemplateProvider`
+- [ ] Create `TemplateManager` class
+
+### Phase 2: Built-in Templates (1 day)
+
+- [ ] Convert current Hello World to embedded template
+- [ ] Add "Blank" template (truly empty)
+- [ ] Add "Dashboard" template (with nav + pages)
+- [ ] Add template metadata and thumbnails
+
+### Phase 3: Integration (0.5 days)
+
+- [ ] Update `LocalProjectsModel` to use `TemplateManager`
+- [ ] Remove programmatic project creation workaround
+- [ ] Update project creation UI to show template gallery
+- [ ] Add template preview/selection dialog
+
+### Phase 4: Advanced Features (0.5 days)
+
+- [ ] Implement template validation
+- [ ] Add template export functionality (for users to create templates)
+- [ ] Support template variables/parameters
+- [ ] Add template upgrade/migration system
+
+## Files to Modify
+
+### New Files
+
+- `packages/noodl-editor/src/editor/src/models/template/ProjectTemplate.ts`
+- `packages/noodl-editor/src/editor/src/models/template/TemplateProvider.ts`
+- `packages/noodl-editor/src/editor/src/models/template/TemplateManager.ts`
+- `packages/noodl-editor/src/editor/src/models/template/providers/EmbeddedTemplateProvider.ts`
+- `packages/noodl-editor/src/editor/src/models/template/templates/` (folder for template definitions)
+  - `hello-world.ts`
+  - `blank.ts`
+  - `dashboard.ts`
+
+### Existing Files to Update
+
+- `packages/noodl-editor/src/editor/src/utils/LocalProjectsModel.ts`
+  - Replace programmatic project creation with template system
+- `packages/noodl-editor/src/editor/src/pages/ProjectsPage/ProjectsPage.tsx`
+  - Add template selection UI
+- `packages/noodl-editor/src/editor/src/utils/forge/` (might be refactored or replaced)
+
+## Testing Strategy
+
+### Unit Tests
+
+- Template provider loading
+- Template validation
+- Project creation from template
+- Template merging/variables
+
+### Integration Tests
+
+- Create project from each bundled template
+- Verify all templates load correctly
+- Test template provider fallback
+
+### Manual Tests
+
+- Create projects from templates in dev mode
+- Create projects from templates in production build
+- Verify all components and nodes are created correctly
+- Test custom template import/export
+
+## Success Criteria
+
+- [ ] New projects can be created from bundled templates reliably
+- [ ] Templates work identically in dev and production
+- [ ] At least 3 high-quality bundled templates available
+- [ ] Template system is extensible for future templates
+- [ ] No file path resolution issues
+- [ ] User can export their project as a template
+- [ ] Documentation for creating custom templates
+
+## Future Enhancements
+
+- **Template Marketplace**: Browse and download community templates
+- **Template Packages**: Include external dependencies/modules
+- **Template Generator**: AI-powered template creation
+- **Template Forking**: Modify and save as new template
+- **Template Versioning**: Update templates without breaking existing projects
+
+## References
+
+- Current implementation: `packages/noodl-editor/src/editor/src/utils/LocalProjectsModel.ts` (lines 295-360)
+- Failed attempt: `packages/noodl-editor/src/editor/src/utils/forge/template/providers/local-template-provider.ts`
+- Template registry: `packages/noodl-editor/src/editor/src/utils/forge/index.ts`
+
+## Related Tasks
+
+- None yet (this is the first comprehensive template system task)
