Stateless vs Stateful Dev Environments
Stateless dev environments reset often; stateful environments preserve sessions, output, and context.

A stateless dev environment assumes you can recreate state on demand. A stateful environment assumes you should not have to.
Stateless (what most tools do)
- sessions die with the tab,
- output disappears after disconnects,
- "re-run everything" is the recovery plan.
Stateful (what you actually need)
- sessions persist across time,
- output is replayed on reconnect,
- context compounds instead of resetting.
Why it matters
Statefulness is the difference between demo workflows and real work. Long-running tasks, deep debugging, and multi-day projects all require a stateful environment.
