+# API Actions and Failure Points
+
+Comprehensive diagrams showing all actions that can be performed on projects, studies, and checklists, including all failure points and error conditions.
+
+## Overview
+
+This document visualizes the complete API surface for the three main entities in CoRATES:
+
+- **Projects**: Backend API routes + Y.js sync operations
+- **Studies**: Y.js operations + PDF management via backend API
+- **Checklists**: Y.js operations only
+
+Each diagram shows:
+
+- All CRUD operations
+- Permission and validation checks
+- External dependencies (D1, R2, Durable Objects)
+- All failure points with error codes
+- Network and sync failures
+
+---
+
+## Project Actions
+
+Projects are managed through both HTTP API endpoints and Y.js synchronization. The backend API handles CRUD operations and member management, while Y.js syncs metadata and member changes to Durable Objects.
