Implements custom step creation forms and backend persistence: Task B.8 - StepForm Component: - Comprehensive form for creating custom steps - Step type selection (decision/action/solution) with descriptions - Required fields: title, instructions (markdown supported) - Optional fields: help text, commands (dynamic array), category, tags - Visibility control (private/team/public) - Save to library checkbox - Full validation with error display - Dynamic command management (add/remove, label + command) - Tag input with Enter key support Task B.9 - CustomStepModal: - Tabbed modal interface - Tab 1: "Type My Own" - embeds StepForm - Tab 2: "Browse Library" - embeds StepLibraryBrowser - Handles both saved steps (API) and drafts (no save) - Loading states during step creation - Error handling with user feedback - Returns Step or CustomStepDraft to parent Task B.10 - Backend Custom Steps Support: - Database migration: add custom_steps JSONB column to sessions - Updated Session model with custom_steps field - Updated SessionResponse schema with custom_steps - Updated SessionUpdate schema to accept custom_steps - Migration ready to run: 4cdb5cba1aff Task B.13 - Session Types Updates: - Added CustomStep and CustomStepDraft interfaces - Updated Session interface with custom_steps field - Updated SessionUpdate interface - Exported step types from types/index.ts - Full TypeScript support for custom step integration Remaining tasks: B.11 (TreeNavigationPage integration), B.12 (Export) Build tested successfully.

Troubleshooting Decision Tree - Backend API
FastAPI backend for the Troubleshooting Decision Tree application.
Quick Start
1. Set up Python environment
cd backend
python -m venv venv
# Windows
venv\Scripts\activate
# macOS/Linux
source venv/bin/activate
pip install -r requirements.txt
2. Start PostgreSQL database
Using Docker:
docker-compose up -d
Or install PostgreSQL locally and create a database:
CREATE DATABASE decision_tree;
3. Configure environment
Copy the example env file and update as needed:
cp .env.example .env
4. Run database migrations
alembic upgrade head
5. Start the server
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
The API will be available at:
- API: http://localhost:8000
- Docs: http://localhost:8000/api/docs
- ReDoc: http://localhost:8000/api/redoc
