Session Persistence & Output Replay
Session persistence keeps work alive; output replay lets you see what happened while you were away.

Session persistence keeps your work alive. Output replay ensures you can see what happened while you were away. Together, they turn long-running work into something you can trust.
Why replay matters
When a task runs for minutes or hours, missing output is not a small inconvenience. It breaks debugging, forces reruns, and makes results unreliable.
Output replay fixes the blind spot: you disconnect, reconnect later, and still see the critical output you missed.
What persistence means
Persistence is more than "the tab stayed open." It means:
- Sessions resume with the same state.
- Output is replayed across disconnects.
- Context stays intact across long gaps.
What to look for
- Bounded replay (recent output retained without turning into a log system).
- Stable session identity to attach to the same run.
- Resume-first design instead of "refresh to recover."
