@owenlin0 Very fair comment! changing now

It seems like we now have a few methods that look similar:

• load_thread_for_running_resume_response
• load_thread_for_cold_resume_response
• load_thread_summary_for_rollout

I think we can make it cleaner. Codex suggests this:

There are really only two concerns here:

• Build the base Thread metadata.
• Populate/merge turns for the resume response.

A cleaner shape would be:

• Keep one metadata loader: load_thread_summary_for_rollout(...) -> Thread
• Add one turn hydrator: populate_resume_turns(thread: &mut Thread, rollout_path, active_turn_override) or similar
• Handle the Forked special case inline or behind a tiny helper like build_thread_summary_for_forked_history(...)

that said, pre-approving. much better already, thanks!
