+### If the result carries a `workspace_handle`, you can read the files

+Some agents (SWE-AF) mirror the workspace they are building in, so you can open
+the actual files instead of reasoning from the summary — including uncommitted
+edits and untracked files that no git push would carry. You do not ask whether
+this is available and there is nothing to configure: the handle is in the result

 ## Hard rules
 
 - Every call goes through the control plane — never POST to an agent's own port.
+  The one exception is a `workspace_handle`: its `ssh://` endpoint is a furrow
+  transport, not the agent's HTTP port, and the per-run token in the handle is
+  what authorizes it. Reading files there is not an agent call.
