Node plus actions should offer a short continuation menu while handle dragging remains a full exploration surface. This records the product rule in a dedicated PRD and implements a static priority filter inside the existing connection menu instead of introducing a separate ranking layer.
Constraint: Test server flow uses the connection drop menu for both drag-created nodes and node plus quick-add actions
Rejected: Split quick-add into a separate menu component | duplicated option compatibility logic and increased drift risk
Confidence: high
Scope-risk: narrow
Directive: Keep quick-add filtering downstream of compatibility filtering so suggestions never create invalid handle connections
Tested: npm run test:run -- src/components/__tests__/ConnectionDropMenu.test.tsx src/components/__tests__/WorkflowCanvas.test.tsx
Tested: npm run test:run
Tested: npm run build
Not-tested: npm run lint; current next lint script is not supported by the installed Next CLI
