Sixth commit in the session-expiration-policy series. The kill-all-
sessions endpoint folded into scope after the §4.11 design pass.
- POST /accounts/me/security/revoke-sessions, owner-only.
- Body: {"scope": "all" | "others"}. Default "all" includes the caller's
own refresh token. "others" preserves the caller's sessions so an
owner can sign everyone else out without logging themselves out.
- Single SQL UPDATE through users.account_id -> refresh_tokens, with
revoked_at IS NULL preserved as the gate so already-revoked rows
don't get double-stamped (the idempotency property).
- Caller's access token is not touched — it dies on its 5-minute timer.
Frontend handles "scope=all" UX by clearing localStorage and
redirecting after the response (commit 8).
- Affected users' next /auth/refresh hits the existing atomic-revoke
zero-rows path -> invalid_refresh_token (plain logout, no banner).
- Writes one account.sessions_revoked_bulk audit event with
{scope, revoked_count}.
Tests added in test_session_policy.py (6 cases):
- #17 scope=all kills caller's own session; their refresh -> 401
invalid_refresh_token.
- #18 scope=others preserves caller's session; their refresh succeeds,
member's refresh -> 401 invalid_refresh_token.
- #19 account-scoped: test_admin in a different account is unaffected
when test_user's owner runs revoke-all (revoked_count=1, not 2).
- #20 engineer-role member -> 403.
- #21 emits exactly one audit row with the expected payload.
- #22 idempotent: second immediate POST returns revoked_count=0.
22/22 in test_session_policy.

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
