## Security Features (Fail-Closed)

All User API endpoints are now protected by a central gatekeeper. If an endpoint is not explicitly mapped in the security registry, it is **denied by default** with a 403 Forbidden response.

### 🛡️ Mandatory Authorization

- **Self-profile updates**: Requires valid session and ownership.
- **Admin actions**: Requires `isAdmin: true` flag in session roles.
- **Role Escalation Protection**: Users are prevented from modifying their own roles.

## Test Helpers

### Mock Event Creation

All User API tests use a standardized `createMockEvent` helper that injects mandatory `roles` and `tenantId` into the request locals.

```
function createMockEvent(pathname: string, method: string = "GET"): RequestEvent {
  return {
    url: new URL(pathname, "http://localhost"),
    request: new Request("http://localhost" + pathname, { method }),
    locals: {
      tenantId: "test-tenant",
      roles: [{ name: "admin", isAdmin: true, permissions: [] }],
    },
  } as unknown as RequestEvent;
}
```
