+them — Pi, OpenCode, Codex, Claude Code, and Claude Managed Agents all drive the same
+core, so a deployment isn't tied to any single vendor.
+
+The first four run the agent loop in-process. Claude Managed Agents runs it as a
+hosted session on Anthropic's servers, which makes QM's brain/hands split physical:
+the brain (harness) is a managed service, and the hands are your sandbox. Tool calls
+come back to QM to run in your sandbox, with your credentials, under the same command
+policy and approvals as the other harnesses.
+
+The hosted Claude brain has stronger resiliency and performance than in-process
+Claude Code. Conversation state lives with the session, so an agent that is mid-task
+during a redeploy of QM survives with its conversation intact, and a turn sends just
+one new message. Claude works with the native bash toolset it knows best, and every
+session has a live trace in the Claude console, which makes debugging an agent much
+easier.
