BLACKVALLEY DEFENSE MISSION-SYSTEM ACCESS BOUNDARY BRIEF Version: 1.0.0 Release date: 2026-08-18 Release state: Public sample AUTHENTICATION ANSWERS ONE QUESTION Authentication establishes who a principal is according to an identity provider. It does not by itself establish authority over a mission object, field, query, action, workflow, or export. APPLICATION ENTITLEMENT REMAINS COARSE A portal can determine whether an authenticated principal may see or launch an application. The launched application still evaluates its own policy against the requested operation and current context. - Keep tokens and sessions scoped to their own application hosts. - Never pass reusable credentials through URLs. - Do not translate an identity-provider role into implicit mission authority. - Fail closed when identity, policy, or required context is unavailable. INTEGRATION CONSEQUENCE Explicit boundaries create more visible interfaces, but they limit blast radius and keep each mission application responsible for its own data, authorization decisions, exports, and audit trail. This is a public reference brief. It does not describe private topology, credentials, entitlements, providers, or deployment state.
