Session Persistence & Output Replay

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."
