#5035 "Sessions: lifetime applied, role and is_active re-read per request, logout is a POST, failed logins throttled". - steward/core/proxy.py: trusted_value / is_https / client_ip read X-Forwarded-Proto and -For only as far as the trusted proxy hops (Settings → General, default 1, 0 = trust none). - The session cookie is Secure, and HSTS is sent, only on requests that arrived over HTTPS by that rule; plain-HTTP and LAN use are unchanged and nothing redirects. - A login lasts Settings → General's session lifetime from when it began (session.permanent + a login_at stamp checked every request — the cookie's own age slides on every response). A deleted or deactivated user is logged out on their next request; a role change applies at once. - Logout is a POST (a form in the sidebar); GET /logout is gone. - Failed logins pause an address after login.max_failures within login.lockout_minutes (Settings → General; defaults 5 in 15 min), keyed by address so nobody can lock a user out by name. Failures are audited as auth.login_failed with the address. - to_access_cfg projects the new settings into app.config at startup and on save, beside the existing projections. - Integration tests seed real users and a login_at, since every request now re-reads the session's user.
