## Problem Design and implement a `WorkspaceManager` that supports multiple tenants. Each workspace has members with roles: `owner`, `admin`, `member`, `viewer`. Operations have different permission requirements. Implement the core class. ```python class WorkspaceManager: def create_workspace(self, owner_id: str, name: str) -> str: ... def invite_member(self, actor_id: str, workspace_id: str, user_id: str, role: str) -> bool: ... def update_role(self, actor_id: str, workspace_id: str, target_id: str, new_role: str) -> bool: ... def remove_member(self, actor_id: str, workspace_id: str, target_id: str) -> bool: ... def get_members(self, actor_id: str, workspace_id: str) -> list[dict]: ... ``` **Permission rules:** - Only `owner`/`admin` can invite or remove members - Only `owner` can change roles of `admin` - `viewer` cannot see member list details ## Follow-ups 1. How do you prevent privilege escalation (e.g., an admin promoting themselves to owner)? 2. What happens if an owner leaves — how do you enforce at least one owner per workspace? 3. How would you audit all permission changes for compliance? 4. Extend this to support workspace-level resource quotas (e.g., max 50 projects per workspace).
