Eighth commit in the session-expiration-policy series. Surfaces all
the owner controls and user-facing expiry UX that the prior commits
plumbed through, designed end-to-end via /plan-design-review (initial
4/10 -> final 9/10; 7 decisions locked in the plan).
Backend additions:
- accounts/me/security GET response gains active_users: list of
{user_id, name, email, last_login_at} for users in this account
with at least one un-revoked refresh token. Joined query on
refresh_tokens + users, distinct, ordered by last_login desc.
Drives the Active Sessions section.
Frontend additions:
- api/accountSecurity.ts: typed client for GET/PATCH/revoke-sessions.
- hooks/useAuthSessionExpiry.ts: reads idle/absolute expiry from the
auth store, returns warning ('none'|'soon'|'now') + reason
('idle'|'absolute') so consumers can pick the right UX for the
closer window. Re-evaluates every 30s.
- components/common/SessionExpiryToast.tsx: top-of-app notice that
fires at T-5min. Idle case: warning-amber tone, [Stay signed in]
button hits authApi.refresh() and updates the store on success.
Absolute case: info-cyan tone, [Sign in now] link to /login (no
recoverable action). Dismissable, doesn't re-fire after dismissal.
- components/account/RevokeSessionsModal.tsx: confirmation modal for
the two bulk-revoke scopes. Title, body, and confirm-label vary by
scope; danger-styled confirm button.
- pages/account/AccountSecuritySettingsPage.tsx: the main page.
Header (Shield icon), intro, Policy card with Strict/Standard/Custom
radios + always-visible-disabled Custom inputs (idle/absolute
minutes) with inline validation, Save button + emerald success ping,
info note about 'applies at next login'. Active sessions card with
count-aware copy, list of {name, email, last-login-ago} rows
(caller tagged '(you)'), two buttons — 'except me' hidden when
count=1, 'sign me out and everyone else' uses danger-tinted styling.
- pages/AccountSettingsPage.tsx: 'Session security' row added to the
owner-only settings list.
- router.tsx: /account/security route, owner-gated via ProtectedRoute.
- pages/LoginPage.tsx: cyan info-tone banner above form when
?reason=session_expired is in the URL.
- components/layout/AppLayout.tsx: mounts <SessionExpiryToast />.
Scope=all bulk-revoke UX (the most jarring moment): on success,
toast.success(N sessions), 1.5s delay, then clear localStorage +
useAuthStore.logout() + window.location='/login' (no banner — the
owner just did this).
Backend tests: existing 22/22 still green plus the GET test now
asserts active_users is present + non-empty after login. Frontend:
tsc clean, authStore test 2/2.

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
