Codex lets host applications plug in their own agent controllers through ThreadManager
GitHub·low signal
Codex PR #47808, merged 24 September, adds `ThreadManager::with_agent_control_factory`, so a host can supply its own agent controller for new and cold-resumed threads. Local control stays the default. Startup fails if the factory errors or the controller's identity doesn't match the session. Follow-up PR #47820 adds integration coverage, which points to Codex being embedded as a runtime inside other orchestrators.
