Motivation + +**Background:** + +Flame currently supports TLS/mTLS for transport-layer security (RFE234), encrypting all communication between components (clients, session manager, executor manager). However, TLS alone does not provide **application-level authentication or authorization**—any client with network access and valid TLS certificates can access any session or application in the cluster. + +Current security gaps: + +1. **No Identity**: Flame cannot identify WHO is making requests beyond TLS certificate validation +2. **No Multi-tenancy**: All sessions, applications, and executors exist in a flat namespace—any client can access any resource +3. **No Authorization**: No way to restrict which clients can access which resources +4. **No Cache Isolation**: Flame instances accessing the Object Cache cannot be distinguished from external clients + +**Target:** + +Implement workspace-based multi-tenancy with mTLS-based authentication to ensure: + +1. **Workspaces**: Logical isolation boundaries for all Flame objects (applications, sessions, executors) +2. **Identity via mTLS**: Client certificates provide cryptographic identity (Subject/CN) +3. **Authorization**: Map certificate subjects to permitted workspaces +4. **Internal Access**: Flame components (executor manager, session manager) can access cache with elevated privileges +5. **Backward Compatibility**: Default `system` workspace maintains current behavior for single-tenant deployments + +## 2. Function Specification + +### 2.1 Workspace Concept + +A **Workspace** is a logical isolation boundary that groups related resources.
