Adds backend/scripts/seed_phase9_qa_fixtures.py — creates 4 ai_sessions plus matching session_suggested_fixes that pre-bake the four backend states the AI orchestrator must produce to mount the five conditional Phase 9 components: A. no template, no draft → ChatTabStrip + ScriptBuilderTab B. ai_drafted_script set → InlineNoTemplateDialog C. script_template_id set → TemplateMatchPanel D. applied_at + status=proposed → EscalateInterceptDialog (verify state) Background: a Phase 9 QA pass against a regular session left these five components unreached because the AI didn't emit SUGGEST_FIX in time/at all. Seeding directly bypasses the AI and lets QA exercise each surface deterministically. UUIDs are deterministic (uuid5 over a fixed namespace) so re-runs upsert. Pass --reset to wipe and recreate. Each session gets two synthetic conversation messages so the chat header's canAct gate (messages.length >= 2) opens up Resolve/Escalate. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
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
