Always-On Dev Environment vs Ephemeral Workspaces
Always-on dev environments keep state across time; ephemeral workspaces reset and force rework.

An always-on dev environment keeps state across time. Ephemeral workspaces reset and force you to rebuild context every time you come back.
The core difference
- Always-on: the session keeps running, output continues, and you resume later.
- Ephemeral: the session ends, output disappears, and you start over.
Why ephemeral resets are expensive
- you repeat setup steps,
- you rerun long tasks,
- you lose confidence in what actually finished.
The continuity-first choice
If your work spans hours or days, an always-on environment is the only model that keeps momentum intact.
