# Session Isolation

> Deep-dive into database sandboxing and workspace isolation.

Hiroshi ensures robust multi-tenant security by isolating all conversation threads.

### Sandbox Isolation Perimeters

* **Database Isolation**: Each session stores its history records inside the common SQLite database keyed strictly by the session identifier.
* **Workspace Sandbox**: Each agent executes its tools and filesystem actions inside dedicated workspace folders:
  * No cross-sandbox lookups are permitted.
  * Allowed subprocess calls are run under restricted environments.
