Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Session timeout Choose session timeout when the authenticated session has already expired or been terminated and the next valid path is sign-in, reauthentication, restart, or safe task restoration. The timeout state is driven by server or identity-provider session validity, not by a cosmetic client-only overlay. Supports inactivity timeout, overall timeout, termination, and reauthentication reset behavior.
Session timeout warning Choose session timeout warning when the session is approaching an inactivity, absolute, device-lock, or reauthentication boundary that can interrupt authenticated work. The warning is driven by the authoritative session or identity state, not only a local countdown. NIST documents inactivity timeout, overall timeout, and reauthentication reset behavior.
