+# Phase 19 Plan 01: Extract Node and Annotation Types Summary
+
+**Extracted node and annotation types from index.ts into focused domain modules with re-exports preserving backward compatibility**
+
+## Performance
+
+- **Duration:** 8 min
+- **Started:** 2026-01-13T20:38:00Z
+- **Completed:** 2026-01-13T20:46:00Z
+- **Tasks:** 3
+- **Files modified:** 3 (2 created, 1 modified)
+
+## Accomplishments
+
+- Created src/types/annotation.ts with BaseNodeData, shape types, AnnotationNodeData, and tool types (95 lines)
+- Created src/types/nodes.ts with NodeType, NodeStatus, all *NodeData types, WorkflowNode, HandleType (180 lines)
+- Updated src/types/index.ts to re-export from domain files, reduced from 365 to 126 lines (-239 lines)
+- Maintained full backward compatibility for all import sites
+- All 1142 tests pass
+
+## Task Commits
+
+Tasks were combined into a single atomic commit due to circular type dependencies:
+
+1. **Tasks 1-3: Extract types to domain files** - `f178b72` (feat)
+
+## Files Created/Modified
+
+- `src/types/annotation.ts` - BaseNodeData, ShapeType, all *Shape types, AnnotationShape, AnnotationNodeData, ToolType, ToolOptions
+- `src/types/nodes.ts` - NodeType, NodeStatus, all *NodeData types (ImageInput, Prompt, NanoBanana, GenerateVideo, LLMGenerate, SplitGrid, Output), WorkflowNodeData union, WorkflowNode, HandleType, ModelInputDef, history item types
+- `src/types/index.ts` - Re-exports from annotation.ts and nodes.ts, keeps model types, edge types, API types, config types, group types, provider types
+
+## Decisions Made
+
+- **BaseNodeData in annotation.ts:** To avoid circular dependencies (nodes.ts imports AnnotationNodeData from annotation.ts), BaseNodeData is defined in annotation.ts as the base module with no imports
+- **Single atomic commit:** Tasks 1-3 are tightly coupled (nodes.ts imports from both annotation.ts and index.ts) - separating them would break compilation
+- **Remaining types in index.ts:** Model types (AspectRatio, Resolution, ModelType), LLM types, Edge types, API types, Config types, Group types, Provider types remain in index.ts for Plan 2
+
+## Deviations from Plan
+
+None - plan executed exactly as written
+
+## Issues Encountered
+
+- Pre-existing TypeScript errors in test files (missing mock properties for React Flow node types) - not related to this refactoring, tests still pass via Vitest
+
+## Next Phase Readiness
+
+- Pattern established for Plan 19-02 (extract provider, workflow, API, and model types)
+- Ready to continue Phase 19 with remaining type extractions
