Implement unified API standard v1.0 across backend and frontend, enhancing error handling, response formatting, and monitoring capabilities. Refactor viewsets for consistent CRUD operations and introduce API Monitor for endpoint health checks. Update migrations to ensure database integrity and remove obsolete constraints and fields. Comprehensive test suite created to validate new standards and functionality.

+## [1.1.0] - 2025-01-XX
+
+### Added
+
+#### Unified API Standard v1.0
+- **Response Format Standardization**
+  - All endpoints return unified format: `{success: true/false, data: {...}, message: "...", errors: {...}}`
+  - Paginated responses include `success`, `count`, `next`, `previous`, `results`
+  - Error responses include `success: false`, `error`, `errors`, `request_id`
+  - Response helper functions: `success_response()`, `error_response()`, `paginated_response()`
+
+- **Custom Exception Handler**
+  - Centralized exception handling in `backend/igny8_core/api/exception_handlers.py`
+  - All exceptions wrapped in unified format
+  - Proper HTTP status code mapping (400, 401, 403, 404, 409, 422, 429, 500)
+  - Debug information included in development mode
+
+- **Custom Pagination**
+  - `CustomPageNumberPagination` class with unified format support
+  - Default page size: 10, max: 100
+  - Dynamic page size via `page_size` query parameter
+  - Includes `success` field in paginated responses
+
+- **Base ViewSets**
+  - `AccountModelViewSet` - Handles account isolation and unified CRUD responses
+  - `SiteSectorModelViewSet` - Extends account isolation with site/sector filtering
+  - All CRUD operations (create, retrieve, update, destroy) return unified format
+
+- **Rate Limiting**
+  - `DebugScopedRateThrottle` with debug bypass for development
+  - Scoped rate limits per module (planner, writer, system, billing, auth)
+  - AI function rate limits (10/min for expensive operations)
+  - Bypass for aws-admin accounts and admin/developer roles
+  - Rate limit headers: `X-Throttle-Limit`, `X-Throttle-Remaining`, `X-Throttle-Reset`
+
+- **Request ID Tracking**
+  - `RequestIDMiddleware` generates unique UUID for each request
+  - Request ID included in all error responses
+  - Request ID in response headers: `X-Request-ID`
+  - Used for log correlation and debugging
+
+- **API Monitor**
+  - New page: `/settings/api-monitor` for endpoint health monitoring
+  - Monitors API status (HTTP response) and data status (page population)
+  - Endpoint groups: Core Health, Auth, Planner, Writer, System, Billing, CRUD Operations
+  - Sorting by status (errors first, then warnings, then healthy)
+  - Real-time endpoint health checks with configurable refresh interval
+  - Only accessible to aws-admin accounts
+
+- **Sidebar API Status Indicator**
+  - Visual indicator circles for each endpoint group
+  - Color-coded status (green = healthy, yellow = warning)
+  - Abbreviations: CO, AU, PM, WM, PC, WC, SY
+  - Only visible and active for aws-admin accounts on API monitor page
+  - Prevents console errors on other pages
+
