feat: Phase 5 - Visual Workflow Editor (Option B)
Backend (Mini-Backend 1-2h):
- Migration 016: ai_prompts.graph_data JSONB column
- workflow_executor: graph_data parameter support (backward-compatible)
- prompt_executor: execute_workflow_prompt uses graph_data
Frontend (Main effort 25-35h):
- WorkflowCanvas: React Flow wrapper component
- 5 Custom Nodes: Start, End, Analysis, Logic, Join
- 4 Config Panels: QuestionAugmentation, LogicExpression, Fallback, Join
- workflowValidation: Structural + logical validation
- workflowSerializer: Canvas ↔ JSONB conversion
- WorkflowEditorPage: Main orchestration (420 LOC)
- Route: /workflow-editor/:id
- CSS: workflowEditor.css (300 LOC)
Architecture:
- Option B: ai_prompts.type='workflow' (not separate table)
- panels/ subdirectory for clean separation
- WorkflowCanvas reusable component
- User GUI identical (Workflows = Prompts)
- Backward-compatible (type='pipeline' unchanged)
Version: v0.9m → v0.9n (Phase 5 complete)
Module: workflow 0.5.0 → 0.6.0
