- SpecRenderer: Add localNodes state with applyNodeChanges for smooth node dragging
- SpecRenderer: Fix getDefaultNodeData() - extractor uses 'custom_function' type with function definition
- SpecRenderer: Fix constraint default - use constraint_type instead of type
- CanvasView: Show config panel INSTEAD of chat when node selected (not blocked)
- NodeConfigPanelV2: Enable showHeader for code editor toolbar (Generate/Snippets/Validate/Test buttons)
- NodeConfigPanelV2: Pass studyId to IntrospectionPanel
- IntrospectionPanel: Accept studyId prop and use correct API endpoint
- optimization.py: Search multiple directories for model files including 1_setup/model/
Backend:
- Add POST /generate-extractor for AI code generation via Claude CLI
- Add POST /generate-extractor/stream for SSE streaming generation
- Add POST /validate-extractor with enhanced syntax checking
- Add POST /check-dependencies for import analysis
- Add POST /test-extractor for live OP2 file testing
- Add ClaudeCodeSession service for managing CLI sessions
Frontend:
- Add lib/api/claude.ts with typed API functions
- Enhance CodeEditorPanel with:
- Streaming generation with live preview
- Code snippets library (6 templates: displacement, stress, frequency, mass, energy, reaction)
- Test button for live OP2 validation
- Cancel button for stopping generation
- Dependency warnings display
- Integrate streaming and testing into NodeConfigPanelV2
Uses Claude CLI (--print mode) to leverage Pro/Max subscription without API costs.
Phase 1 - Foundation:
- Add NodeConfigPanelV2 using useSpecStore for AtomizerSpec v2.0 mode
- Deprecate AtomizerCanvas and useCanvasStore with migration docs
- Add VITE_USE_LEGACY_CANVAS env var for emergency fallback
- Enhance NodePalette with collapse support, filtering, exports
- Add drag-drop support to SpecRenderer with default node data
- Setup test infrastructure (Vitest + Playwright configs)
- Add useSpecStore unit tests (15 tests)
Phase 2 - File Structure & Model:
- Create FileStructurePanel with tree view of study files
- Add ModelNodeV2 with collapsible file dependencies
- Add tabbed left sidebar (Components/Files tabs)
- Add GET /api/files/structure/{study_id} backend endpoint
- Auto-expand 1_setup folders in file tree
- Show model file introspection with solver type and expressions
Technical:
- All TypeScript checks pass
- All 15 unit tests pass
- Production build successful
