How Long-Running Dev Sessions Actually Work

Long-running dev sessions only work when the environment is built to survive time. Otherwise, the session resets and the work becomes untrustworthy.

The short answer

A long-running session requires:

• session persistence (the work keeps running),
• output replay (you can see what happened),
• resume without re-run (state stays intact).

What breaks in typical setups

• connection drops end the session,
• output is lost while you are away,
• the only recovery path is a restart.

The continuity-first fix

Treat the environment as always-on and resume-first. The session is the asset, not the socket.
