Phase O Task 46 needs internal validation of the full self-serve flow against the prod backend before flipping SELF_SERVE_ENABLED public. This adds the per-email allowlist that bypasses the global flag for specific authenticated users. - INTERNAL_TESTER_EMAILS: comma-separated list, parsed by a Pydantic field_validator into a normalized lowercase list. Settings.is_internal_tester and Settings.is_self_serve_active_for centralize the allowlist + global-flag check; both endpoints below call the latter. - New get_current_user_optional dep — best-effort auth that returns None on missing/invalid token instead of 401. Used by /config/public so the same endpoint serves anonymous public callers and authenticated allowlist members. - /config/public now accepts optional auth and returns self_serve_enabled=True for authenticated allowlist members even when the global flag is off. Anonymous callers always see the global flag. - /auth/register replaces the SELF_SERVE_ENABLED check with the helper so a registering email on the allowlist can join without an invite code. Non-allowlist emails still 400 when self-serve is off. - docker-compose.dev.yml passes SELF_SERVE_ENABLED + INTERNAL_TESTER_EMAILS through; backend/.env.example documents both. Tests cover: allowlisted authenticated user sees true, non-allowlisted authenticated user sees the global flag, anonymous calls ignore the allowlist, allowlisted email registers without invite code, non-allowlisted email still blocked.

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
