Michael Chihlas 9ec208f6e7 feat(deps): add require_active_subscription guard with allowlist
Mounts on Pro routers (trees, sessions, scripts, FlowPilot, etc.) and
returns 402 with structured detail when an account's subscription is
missing or locked. Allowlist bypasses billing/account/auth flows so
users can recover from a lapsed subscription.

Conftest now seeds a default Pro/active Subscription on test_user and
test_admin (delete-then-insert because the register endpoint already
creates a free/active sub by default). Two existing tests adapted to
the new seeded plan; tenant-isolation tests seed Subscription rows for
the accounts they create directly.

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:
