## Versioning System

### Version Format

**Format:** `MAJOR.MINOR.PATCH` (Semantic Versioning)

- **MAJOR**: Breaking changes, major feature additions, architecture changes
- **MINOR**: New features, new modules, significant enhancements
- **PATCH**: Bug fixes, small improvements, documentation updates

**Current Version:** `1.0.0`

### Version Tracking

**Location:** 
- Root `CHANGELOG.md` - Main version history
- Each documentation file header - Last updated date

**Version Update Rules:**
- **MAJOR**: Only updated when user confirms major release
- **MINOR**: Updated when user confirms new feature is complete
- **PATCH**: Updated when user confirms bug fix is complete

### Version Update Process

1. **Code Change Made**: Developer/AI makes code changes
2. **User Confirmation**: User confirms fix/feature is complete
3. **Version Update**: Update version in CHANGELOG.md
4. **Changelog Entry**: Add entry to CHANGELOG.md
5. **Documentation Update**: Update relevant documentation files if needed

**IMPORTANT**: Never update version or changelog without user confirmation that the change is complete and working.

## Changelog Management

### Changelog Location

**File:** `/CHANGELOG.md` (root directory)

### Changelog Structure

```markdown
## [Version] - YYYY-MM-DD

### Added
- New features, modules, or capabilities

### Documentation Update Checklist

- [ ] Identify which documentation file(s) need updating
- [ ] Update the relevant section(s)
- [ ] Update "Last Updated" date in file header
- [ ] Add changelog entry (after user confirmation)
- [ ] Verify all links still work
- [ ] Ensure consistency across all documentation

### Documentation Standards

1. **No Code Snippets**: Documentation focuses on workflows, features, and architecture
2. **Complete Coverage**: All features and workflows must be documented
3. **Accurate State**: Documentation must reflect current system state
4. **Clear Structure**: Use consistent headings and formatting
5. **Cross-References**: Link related sections and documents

## DRY Principles & Standards

### DRY (Don't Repeat Yourself) Philosophy

**Core Principle**: Use existing, predefined, standardized components, utilities, functions, and configurations instead of creating parallel systems or duplicating code.

### Frontend DRY Standards

#### Components

**MUST USE Existing Components:**
- **Templates**: Use 4 universal templates (DashboardTemplate, TablePageTemplate, FormPageTemplate, SystemPageTemplate)
- **UI Components**: Use components from `/frontend/src/components/`
- **Common Components**: Use ScrollToTop, GlobalErrorDisplay, LoadingStateMonitor
- **Form Components**: Use existing form components with props and configs

**DO NOT:**
- Create new templates when existing ones can be used
- Duplicate component logic
- Create parallel component systems
- Hardcode UI elements that can use config-driven approach

#### Configuration-Driven Development

**MUST USE Configuration Files:**
- **Page Configs**: `/frontend/src/config/pages/` - Define page structure
- **Snippet Configs**: `/frontend/src/config/snippets/` - Define reusable snippets
- **Route Configs**: `/frontend/src/config/routes.config.ts` - Define routes
- **API Configs**: Use existing API client patterns

**DO NOT:**
- Hardcode page structures
- Create pages without config files
- Duplicate configuration patterns

#### State Management

**MUST USE Existing Stores:**
- **Zustand Stores**: Use stores from `/frontend/src/stores/`
  - Auth Store, Site Store, Sector Store
  - Planner Store, Writer Store, Billing Store
  - Settings Store, Page Size Store, Column Visibility Store
- **React Contexts**: Use contexts from `/frontend/src/contexts/`
  - Theme Context, Sidebar Context, Header Metrics Context, Toast Context

**DO NOT:**
- Create new stores for existing functionality
- Duplicate state management logic
- Create parallel state systems

#### Utilities & Helpers

**MUST USE Existing Utilities:**
- **API Client**: Use `/frontend/src/services/api.ts` patterns
- **Hooks**: Use custom hooks from `/frontend/src/hooks/`
- **Utils**: Use utility functions from `/frontend/src/utils/`
- **Constants**: Use constants from `/frontend/src/constants/`

**DO NOT:**
- Create duplicate utility functions
- Implement API calls without using existing patterns
- Create new helper functions when existing ones work

#### CSS & Styling

**MUST USE:**
- **Tailwind CSS**: Use Tailwind utility classes
- **Existing Styles**: Use predefined styles and classes
- **Component Styles**: Use component-level styles from existing components
- **Theme System**: Use theme context for dark/light mode

**DO NOT:**
- Create custom CSS when Tailwind classes exist
- Duplicate styling patterns
- Create parallel style systems
- Hardcode colors or spacing values

### Backend DRY Standards

#### Base Classes

**MUST USE Existing Base Classes:**
- **AccountModelViewSet**: For account-isolated models
- **SiteSectorModelViewSet**: For site/sector-scoped models
- **AccountBaseModel**: For account-isolated models
- **SiteSectorBaseModel**: For site/sector-scoped models

**DO NOT:**
- Create new base classes when existing ones work
- Duplicate filtering logic
- Create parallel isolation systems

#### AI Framework

**MUST USE AI Framework:**
- **BaseAIFunction**: Inherit from this for all AI functions
- **AIEngine**: Use for executing AI functions
- **AICore**: Use for AI API calls
- **PromptRegistry**: Use for prompt management
- **run_ai_task**: Use this Celery task entry point

**DO NOT:**
- Create new AI function patterns
- Duplicate AI execution logic
- Create parallel AI systems

#### Utilities & Services

**MUST USE Existing Services:**
- **CreditService**: For credit management
- **Content Normalizer**: For content processing
- **AI Functions**: Use existing 5 AI functions
- **Middleware**: Use AccountContextMiddleware, ResourceTrackerMiddleware

**DO NOT:**
- Create duplicate service logic
- Implement credit management without CreditService
- Create parallel utility systems

### DRY Violation Detection

**Red Flags:**
- Creating new components when similar ones exist
- Duplicating API call patterns
- Creating new state management when stores exist
- Hardcoding values that should be config-driven
- Creating parallel systems for existing functionality

**Action Required:**
- Check existing components, utilities, and patterns first
- Refactor to use existing systems
- Update documentation if new patterns are truly needed
