The sandbox doesn't get discarded. It gets a domain.

Your agent spends three hours building the app: dependencies installed, database seeded, daemon configured, tests green. On an ephemeral sandbox platform, the next step is extraction: export the artifacts, rebuild the environment somewhere permanent, deploy, and discover which of the three hours didn't survive the move.

On Hoody, there is no move. The container the agent worked in has been serving HTTP since the moment it was created. The app the agent just finished is already answering at the container's URL. Point a domain at it, and the sandbox is production.

The gap between "the agent got it working" and "it's live" used to be a migration. Now it's DNS.
