Scale to zero, really.

Idle endpoints suspend after 5 minutes. Pay storage only — no per-hour compute floor. The OG noble-gas idea.

Wake on first packet.

First connect after create is 10–30s. Reconnects after suspend are fast enough that ORMs never see a timeout.

Branch

Copy-on-write per branch.

Branches are pointers, not copies. Spin one up, run a destructive migration, throw it away. Free below the delta.
