## ⚠️ Known Remaining Work (2 Legacy Components)

These components need **major refactoring** to fully remove deprecated field references:

### 1. **`src/components/common/ToggleTableRow.tsx`**
**Issue:** Extensive fallback logic for `primary_keyword`, `meta_description`, `tags`, `categories`  
**Impact:** Low (falls back to empty when fields don't exist)  
**Fix Required:** Refactor to use only `taxonomy_terms` array

### 2. **`src/pages/Sites/PostEditor.tsx` (SEO/Metadata Tabs)**
**Issue:** SEO tab has inputs for `meta_title`, `meta_description`, `primary_keyword`, `secondary_keywords`  
**Issue:** Metadata tab has tag/category management for deprecated fields  
**Impact:** Medium (UI sections don't work, but don't break core functionality)  
**Fix Required:** Complete UI redesign for these tabs

## 🎯 Application Status

### ✅ Functional Features
- ✅ Planner module (Keywords, Clusters, Ideas)
- ✅ Writer module (Tasks, Content, Dashboard)
- ✅ Sites module (List, Content browsing)
- ✅ Cluster detail pages with content filtering
- ✅ Content creation and editing (basic)
- ✅ API calls using new schema
- ✅ Table/Grid views with correct columns

### ⚠️ Partially Functional
- ⚠️ PostEditor (Content tab works, SEO/Metadata tabs broken)
- ⚠️ Optimizer (content selection works, analysis displays partial data)
- ⚠️ Content metadata display (shows title only, no SEO fields)

### ❌ Non-Critical Broken Features
- ❌ PostEditor SEO tab
- ❌ PostEditor Metadata tab
- ❌ Content filter by sync status (Optimizer)
- ❌ ToggleTableRow metadata expansion (shows minimal data)

## 🔧 Developer Notes

### Field Mapping Reference
```typescript
// OLD SCHEMA → NEW SCHEMA
entity_type         → content_type (enum: post, page, product, service, category, tag)
cluster_role        → (removed)
sync_status         → (removed from Content, kept for Integration)
meta_title          → title (just use title directly)
meta_description    → (removed - not in backend Content model)
primary_keyword     → (removed)
secondary_keywords  → (removed)
tags                → taxonomy_terms (filter by taxonomy === 'tag')
categories          → taxonomy_terms (filter by taxonomy === 'category')
word_count          → (removed)
generated_at        → created_at
task_id             → (removed - OneToOne relationship removed)
html_content        → content_html (renamed for consistency)
```

### Status Value Changes
```typescript
// Task Status
OLD: 'pending' | 'in_progress' | 'completed'
NEW: 'queued' | 'completed'

// Content Status
OLD: 'draft' | 'review' | 'publish'
NEW: 'draft' | 'published'
```

### Content Type Changes
```typescript
// Content Type (formerly entity_type)
OLD: 'blog_post' | 'article' | 'guide' | 'tutorial'
NEW: 'post' | 'page' | 'product' | 'service' | 'category' | 'tag'

// Content Structure
OLD: 'cluster_hub' | 'landing_page' | 'pillar_page' | 'supporting_page'
NEW: 'article' | 'listicle' | 'guide' | 'comparison' | 'product_page'
```

## 🚀 Next Steps

1. **Build Test** ✅ **COMPLETE**
   ```bash
   cd frontend
   npm run build
   ```
   - ✅ Zero TypeScript errors
   - ✅ Build completes successfully in ~9-10s
   - ⚠️ Minor CSS warnings (browser compatibility, not errors)

2. **Run Application**
   ```bash
   npm run dev
   ```
   - Core functionality should work
   - PostEditor SEO/Metadata tabs will show UI but won't save data
   - Content listings will display correctly

3. **Refactor Remaining Components** (priority order)
   - HIGH: PostEditor SEO/Metadata tabs (user-facing)
   - MEDIUM: ContentFilter component (visible but low impact)
   - LOW: ToggleTableRow (edge case display)
   - LOW: OptimizationScores (internal interface)

## 📝 Breaking Changes Summary

**For Backend API Consumers:**
- Content creation no longer requires `task_id`
- Content responses include `taxonomy_terms` array instead of `tags`/`categories`
- Status values changed (see above)

**For Frontend Developers:**
- Import path changes: `Content` interface updated in `services/api.ts`
- Config files use new column definitions
- Default form values changed (check `formData` initialization)
- Status filters must use new enum values
