Identity Model

The public memory API supports these identity fields:

• tenant_id
• user_id
• agent_id
• session_id
• scope

Recommended rules:

• tenant_id / user_id / agent_id / session_id are hard isolation boundaries
• scope is a soft visibility label defined by the upstream business layer
• do not rely on agent_id alone in multi-user systems

Recommended Usage

• single-user app: keep one user_id, leave tenant_id empty or defaulted
• multi-user app: always pass user_id explicitly
• multi-agent system: use different agent_id values per agent
• shared business space: use scope such as private, shared, or team:*
