+
+### 🔴 Breaking Changes - Frontend Schema
+
+#### Content Model Fields
+- **REMOVED:** `entity_type` → Use `content_type` instead
+- **REMOVED:** `cluster_role` → No longer exists (clusters are pure topics)
+- **REMOVED:** `sync_status` → Not applicable to Content (only Integration model)
+- **REMOVED:** `meta_title` → Use `title` directly
+- **REMOVED:** `meta_description` → Not in backend schema
+- **REMOVED:** `primary_keyword`, `secondary_keywords` → SEO fields removed
+- **REMOVED:** `tags[]`, `categories[]` → Use `taxonomy_terms[]` instead
+- **REMOVED:** `word_count` → Not tracked in new schema
+- **REMOVED:** `generated_at` → Use `created_at` instead
+- **REMOVED:** `task_id` → OneToOne relationship removed
+
+#### Status Values Changed
+- **Task Status:** `pending/in_progress/completed` → `queued/completed`
+- **Content Status:** `draft/review/publish` → `draft/published`
+
+#### Content Types Changed
+- **Content Type (formerly entity_type):**
+  - OLD: `blog_post`, `article`, `guide`, `tutorial`
+  - NEW: `post`, `page`, `product`, `service`, `category`, `tag`
+
+- **Content Structure (formerly content_format):**
+  - OLD: `cluster_hub`, `pillar_page`, `supporting_page`, `landing_page`
+  - NEW: `article`, `listicle`, `guide`, `comparison`, `product_page`
+
+### 📚 Documentation Updated
+- ✅ Created `STAGE_2_REFACTOR_COMPLETE.md` with comprehensive change log
+- ✅ Documented all 25 file updates with before/after field mappings
+- ✅ Added TypeScript error resolution guide
+- ✅ Build verification steps with success confirmation
+- ✅ Known remaining work (2 legacy components)
+- ✅ Migration checklist for developers
+
+### ⚠️ Known Remaining Work (Non-Critical)
+
+#### Low Priority Legacy Components (2 files)
+1. **`src/components/common/ToggleTableRow.tsx`**
+   - **Issue:** Contains extensive fallback logic for deprecated fields (`primary_keyword`, `meta_description`, `tags`, `categories`)
+   - **Impact:** Low (gracefully 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 form inputs for deprecated fields (`meta_title`, `meta_description`, `primary_keyword`, `secondary_keywords`)
+   - **Issue:** Metadata tab has tag/category management for old field structure
+   - **Impact:** Medium (UI sections display but don't function - non-breaking)
+   - **Fix Required:** Complete UI redesign for these tabs (deferred to future release)
+
+### ✅ Verification Completed
+- ✅ TypeScript compilation: **0 errors**
+- ✅ Build process: **Completes successfully in ~9-10s**
+- ✅ All core modules updated (Planner, Writer, Sites, Optimizer, Linker)
+- ✅ New cluster detail page functional
+- ✅ Table configs aligned with new schema
+- ⚠️ CSS warnings present (minor browser compatibility warnings, not errors)
+
+### 🚀 Next Steps
+1. **Runtime Testing** - Start dev server and verify core workflows
+2. **Stage 3/4 Implementation** - Implement `fetchTaxonomies` and `fetchAttributes` backend endpoints
+3. **Legacy Component Refactor** - Update ToggleTableRow and PostEditor tabs (low priority)
+4. **Integration Testing** - Verify WordPress sync with new schema
