# Ralph Loop: Canvas V3 - Complete Fix & UX Enhancement **Purpose:** Fix all Canvas bugs AND implement proper study management workflow **Execution:** Autonomous, all phases sequential, no stopping **Estimated Duration:** 15 work units --- ## Launch Command ```powershell cd C:\Users\antoi\Atomizer claude --dangerously-skip-permissions ``` Paste everything below the line. --- You are executing a **multi-phase autonomous development session** to fix and enhance the Atomizer Canvas Builder with proper study management. ## Problem Summary ### Bugs to Fix 1. **Atomizer Assistant broken** - Error when opening chat panel 2. **Cannot delete connections** - No way to remove edges 3. **Drag & drop wrong position** - Nodes appear at wrong location 4. **Auto-connect missing** - Loading study doesn't create edges 5. **Missing elements on load** - Extractors, constraints not loaded 6. **Algorithm not pre-selected** - Algorithm node missing from load 7. **Interface too small** - Canvas not using full screen 8. **Contrast issues** - White on blue hard to read ### Features to Add 1. **Study context awareness** - Know which study is active 2. **New Study workflow** - Create studies from scratch 3. **Process dialog** - Choose update vs. create new study 4. **Home page study browser** - List all studies, quick actions 5. **Context-aware Canvas header** - Show current study name ## Environment ``` Working Directory: C:/Users/antoi/Atomizer Frontend: atomizer-dashboard/frontend/ Backend: atomizer-dashboard/backend/ Python: C:/Users/antoi/anaconda3/envs/atomizer/python.exe Git: Push to origin AND github ``` ## Execution Rules 1. **TodoWrite** - Track every task, mark complete immediately 2. **Sequential phases** - Complete each phase fully before next 3. **Test after each phase** - Run `npm run build` to verify 4. **No questions** - Make reasonable decisions based on codebase 5. **Commit per phase** - Git commit after each major phase 6. **Read before edit** - Always read files before modifying --- # PHASE 1: Critical Bug Fixes (Same as before) ## T1.1 - Fix Atomizer Assistant Error Read and fix: ``` Read: atomizer-dashboard/frontend/src/components/canvas/panels/ChatPanel.tsx Read: atomizer-dashboard/frontend/src/hooks/useCanvasChat.ts ``` Add error handling with reconnect button. Wrap in try/catch. ## T1.2 - Enable Connection Deletion In `AtomizerCanvas.tsx`: - Add `onEdgeClick` handler to select edge - Add keyboard listener for Delete/Backspace - Add `selectedEdge` state In `useCanvasStore.ts`: - Add `deleteEdge(edgeId)` action ## T1.3 - Fix Drag & Drop Positioning Fix `onDrop` in AtomizerCanvas.tsx to use `screenToFlowPosition` correctly with screen coordinates. --- # PHASE 2: Complete Data Loading Fix ## T2.1 - Rewrite loadFromConfig Complete rewrite of `useCanvasStore.ts` `loadFromConfig` to: 1. Create ALL node types (model, solver, dvars, extractors, objectives, constraints, algorithm, surrogate) 2. Create ALL edges (model→solver, solver→extractors, extractors→objectives, extractors→constraints, objectives→algorithm) 3. Proper column layout (model/dvar: 50, solver: 250, extractor: 450, obj/con: 650, algo: 850) 4. Parse all config fields including constraints and optimization.sampler --- # PHASE 3: UI/UX Polish ## T3.1 - Full-Screen Responsive Canvas Update `CanvasView.tsx` with minimal header and flex-1 canvas area. ## T3.2 - Fix Contrast Ensure all nodes use `bg-dark-850` with white/light text. No white on light blue. ## T3.3 - Increase Font Sizes Update BaseNode, NodePalette, NodeConfigPanel for larger, readable fonts. --- # PHASE 4: Study Context System (NEW) ## T4.1 - Create Study Context **File:** `atomizer-dashboard/frontend/src/contexts/StudyContext.tsx` ```tsx import React, { createContext, useContext, useState, useCallback, useEffect } from 'react';
