Security is architecture, not a feature.

Each organization operates in a logically isolated environment. Data, workflows, memory and configurations do not cross organizational boundaries without explicit, governed permission. Isolation is the default state — not something that must be configured.

Components, AI agents, integrations and user roles operate with the minimum level of access required for their defined function. Elevated access requires explicit authorization through the governance model that Core enforces.

Operational actions, data access events and system interactions are logged across the ecosystem. This provides the traceability needed for governance, audit and incident investigation without requiring separate logging infrastructure for each component.

Operational policies — access rules, automation permissions, data handling requirements, escalation paths — are defined centrally through Elysium Core and applied consistently across all components. Policy changes propagate through the system rather than requiring configuration updates in each component separately.

Organizational memory and operational data are protected by the governance model. Private organizational data does not leave its organizational context without explicit authorization. The memory promotion model ensures that knowledge does not carry private data to higher layers when being shared.

External system connections through Nexus are subject to governance policies before data enters the operating environment. Incoming data is normalized and policy-checked. Outbound data flows through the same governance boundary.
