(approximation based on node size and pin type) ... +} +``` + +**Why This Works**: +1. Pin renderers store exact pivot position during rendering +2. Position is stored in screen space +3. Convert to relative offset from node origin +4. Apply offset to current/target node position +5. Result: pixel-perfect link connection + +### Link Direction + +Link direction is determined by pin type and position: + +```cpp +static ImVec2 GetPinDirection(Pin* pin) +{ + // Use pin renderer data if available + if (pin->HasPositionData) { + // Calculate from pin position relative to node center + ImVec2 nodePos = ed::GetNodePosition(pin->Node->ID); + ImVec2 nodeSize = ed::GetNodeSize(pin->Node->ID); + ImVec2 nodeCenter = nodePos + nodeSize * 0.5f; + ImVec2 pinPos = pin->LastPivotPosition; + + ImVec2 dir = pinPos - nodeCenter; + float len = sqrtf(dir.x * dir.x + dir.y * dir.y); + return len > 0.0f ?

`pathfinding.h` +- [ ] Define `NodeContext` structure in `pathfinding.h` +- [ ] Define `RoutingContext` structure in `pathfinding.h` +- [ ] Add `RoutingStrategy` enum in `pathfinding.h` +- [ ] Update includes if needed (may need node/pin type definitions) + +### Phase 2: Extract Helper Functions (Medium Risk) +- [ ] Extract geometry helpers (`IsSameBlock`, `NodesOverlapX`, etc.) +- [ ] Extract clearance calculation helpers +- [ ] Extract obstacle detection helpers +- [ ] Test each helper function independently +- [ ] Update existing code to use helpers where possible + +### Phase 3: Extract Routing Strategy Functions (High Risk) +- [ ] Extract `RouteSameBlock` (lines ~161-200 in current code) +- [ ] Extract `RouteZShape` (lines ~213-637 in current code) + - [ ] Handle simple Z-shape case + - [ ] Handle Z-shape with obstacle routing + - [ ] Handle Z-shape above/below block variants +- [ ] Extract `RouteUShape` (lines ~641-787 in current code) + - [ ] Handle U-shape above blocks + - [ ] Handle U-shape below blocks + - [ ] Handle side routing variants +- [ ] Extract `RouteHorizontalFlow` (lines ~790-847 in current code) +- [ ] Extract `RouteLShape` (lines ~848-855 in current code) +- [ ] Extract `RouteAroundObstacles` (complex routing logic) +- [ ] Test each routing function with existing test cases + +### Phase 4: Implement Strategy Selection (Medium Risk) +- [ ] Implement `SelectStrategy` function + - [ ] Handle same-block detection + - [ ] Handle vertical flow (down to up) + - [ ] Handle horizontal flow + - [ ] Handle generic cases +- [ ] Implement main `GenerateWaypoints` dispatcher +- [ ] Test strategy selection logic + +### Phase 5: Add Enhanced Context Support (Future Enhancement) +- [ ] Modify calling code to pass `Node*` and `Pin*` objects instead of just positions +- [ ] Populate `PinContext` with actual pin metadata (type, kind, etc.) +- [ ] Populate `NodeContext` with actual node metadata (type, block type, etc.) +- [ ] Use metadata to make smarter routing decisions +- [ ] Example: Use pin type to determine if special routing is needed + +### Phase 6: Backward Compatibility & Testing (Low Risk) +- [ ] Keep old function signature as convenience overload +- [ ] Test all existing call sites still work +- [ ] Run regression tests +- [ ] Update any documentation + +## File Organization + +``` +pathfinding.h + - Context structures (PinContext, NodeContext, RoutingContext) + - RoutingStrategy enum + - Function declarations + +pathfinding.cpp + - Helper functions + - Strategy selection (SelectStrategy) + - Routing strategy implementations + - Main GenerateWaypoints dispatcher + - Backward compatibility overload +``` + +## Testing Strategy + +1. **Unit Tests for Helpers**: Test each helper function with known inputs +2. **Integration Tests**: Test each routing strategy with sample scenarios +3. **Regression Tests**: Verify existing call sites produce same results +4. **Visual Tests**: Manually verify routing looks correct in the UI + +## Benefits + +1. **Maintainability**: Each routing strategy is isolated and easy to modify +2. **Testability**: Small functions are easier to unit test +3. **Extensibility**: Adding new routing strategies is straightforward +4. **Readability**: Clear separation of concerns, easier to understand +5. **Context Awareness**: Can make smarter decisions with full node/pin context +6. **Performance**: Potential for optimization within individual strategies + +## Migration Notes + +- Keep old function signature for backward compatibility +- Gradually migrate call sites to use context objects +- All existing code should continue to work during transition + +## Open Questions + +1. **Node/Pin Type Dependencies**: Do we need to include full `Node*` and `Pin*` pointers, or just metadata? + - Answer: Start with metadata, can add pointers later if needed + +2. **Obstacle Collection**: Should obstacles be part of context or passed separately? + - Answer: Part of context for consistency + +3. **Error Handling**: How should we handle invalid contexts (e.g., invalid bounds)? + - Answer: Return empty waypoint list and log warning + +4. **Constants**: Should clearance constants stay in namespace or move to context? + - Answer: Keep in namespace Constants for now, can be made configurable later + diff --git
