+### Documentation Accuracy & Launch Preparation
+
+This release focuses on ensuring 100% documentation accuracy and establishing maintainability standards for launch.

+---
+
+### 🔧 API Documentation Fixes
+
+**Problem Resolved:**
+- Swagger UI (`/api/docs/`) and ReDoc (`/api/redoc/`) were returning 500 errors
+- Root cause: Serializer field mismatches in `settings_serializers.py`
+
+**Fixes Applied:**
+- `AccountSettingsSerializer`: Changed `config` → `value` to match model
+- `ModuleSettingsSerializer`: Removed non-existent `config` field
+
+**Verified:**
+- Schema endpoint returns valid OpenAPI YAML
+- Both documentation UIs now accessible
+
+---
+
+### 📚 Root-Level Documentation
+
+**New Files Created:**
+| File | Purpose |
+|------|---------|
+| `/INDEX.md` | Quick-start documentation index |
+| `/DESIGN-GUIDE.md` | Mandatory UI/UX standards |
+| `/.cursorrules` | Development rules & standards |
+
+---
+
+### 📊 Documentation Audit Results
+
+**Codebase Metrics Verified:**
+- Routes: 100 (documented in PAGES.md)
+- Models: 52+ (documented in MODELS.md)
+- Zustand Stores: 11 (documented in STORES.md)
+- Celery Tasks: 25+ (documented per module)
+
+**Files Cleaned:**
+- `docs/30-FRONTEND/PAGES.md`: Removed duplicate content, rebuilt from scratch
+
+---
+
+### 📋 Maintainability Standards
