+### `exec` timeouts
+
+`exec` is long-running: the client sends no timeout by default, so the call waits for the command to exit. Pass `timeout` (seconds) to cap how long the client waits. When the timeout elapses, the SDK raises `SandboxTimeoutError` and does not retry, since the command may still be running server-side.
+
+```python
+from porter_sandbox import SandboxTimeoutError
+
+try:
+    result = sandbox.exec(["sleep", "120"], timeout=30.0)
+except SandboxTimeoutError:
+    print("exec exceeded 30s; the command may still be running in the sandbox")
+```
+
+The client-wide `timeout` on `Porter` still applies to every other request (30 seconds by default).
+
 ## Volumes
 
 Volumes are persistent storage that can be mounted into sandboxes.
