[Copilot]

Code Review Analysis for PR #1323: Frontend Block Search Feature

Based on comprehensive analysis of the PR files, review comments, and codebase, here are the critical issues and improvements needed:

Critical Issues (Must Fix)

• Fix IBlockSearchResult type - remove never fields causing unconstructable type
• Prevent keyboard handler from hijacking Ctrl/Cmd+F in input fields
• Fix infinite loop performance issue in BlockSearchPanel rendering
• Replace direct DOM manipulation with React state for block highlighting

Code Quality Issues (Should Fix)

• Rename getBlockType function for consistency (was determineType)
• Complete EntityType.BLOCK_SEARCH integration in service layers
• Remove duplicate BlockType enums to prevent type drift
• Replace custom ErrorState with MUI Alert/Snackbar components

Performance & UX Improvements (Nice to Have)

• Add debouncing to search requests to reduce API calls
• Improve accessibility with proper aria-labels and semantics
• Fix scroll/layout issues with search panel
• Add proper loading and error states

Testing & Validation

• Validate TypeScript compilation with fixed types
• Test keyboard navigation and accessibility
• Verify search functionality with both scopes
• Test block focusing and highlighting behavior

Files to Modify

• frontend/src/types/block.types.ts - Fix type definition
• frontend/src/components/visual-editor/v2/Diagrams.tsx - Fix keyboard handler
• frontend/src/components/visual-editor/BlockSearchPanel.tsx - Fix render loop
• frontend/src/components/visual-editor/hooks/useVisualEditor.tsx - Replace DOM manipulation
• frontend/src/utils/block.utils.ts - Function naming consistency
